Media History - Essay ExampleAs the report declargons the mention of bill should not be construed as a mirror of the past in totality for various reasons, and there are various points that anyone studying history in media or any other field should be aware about when trying to unveil its the two meanings. One of the matters concerning history is that there are epistemological as well as philosophical assumptions that many historiographers make with regards to the proper way in which history should be done. One of those assumptions is where we are meant to trust that history can correspond with reality in the past by reading its contents. The misconception that history is a true reflection of the past is indeed cost noting in media studies out of knowledge that the history presented to us entails many life philosophies in its construction.According to the research findings history is always made for someone and thus it has a purpose as opposed to the past, which remains just as t he past. It is through this understanding that one learning media history is suitable to know that every historian gives an account concerning something with the chief intent that someone in later time will get to read or go through their documentation unlike the past. In addition, history is ideological and not innocent as it appears unlike the past in that, its construction encompasses a historians moral judgment concerning the wrong and the good as well as depending on how they perceive the world.

Marketing Mix Recommendations - Essay ExampleHygiene is one of the important factors within the food industry and consumers give highest priority to it. consequently it is highly recommended that the partnership should only sell hygienic and fresh foods. The pricing should be done on the basis of cost plus pricing manner and commercialise penetration strategy can be followed to grab more market theatrical role. Regarding the promotional aspect, the company can effectively use television and report advertisement as both the media have mass reach. Finally regarding the distribution, the company can appoint distributors and target food marts to distribute and sell their carrefours. Memorandum visualize 18th October, 2012. Subject Organic Food for the family Unit To The Big Boss From Consumer Research Department To maintain sustainability of a business, it is extremely important to keep patronise on the present market share. However after a certain point of time it becomes esse ntial to focus on the ways by which market share can be increased. Greater market share helps in change magnitude the brand recognition. There are some interesting facts about increasing market share. Increasing market share is important only when the company is earning more profits. However it does not have any importance when the market share has increased but the company is losing money. Now in the context of project, Mintel can increase the market share for organic foods and drinks market by considering modifications in their selling mix. Hence following are the recommendations to Mintel for the primary rationale of attaining more market share. Product Recommendation For an organization to get success in the market tell it is imperative to give highest priority to its product stagey (Mcgrath 1-5). Similarly for food industry product is the ultimate element for which a customer pays to the company. Study reveals that among 2000 mountain, 30 % of the respondents are highly con cerned about the safety of foods. Hence for Mintel product strategy should be considered as the central business strategy. Also the product strategy of an organic food company plays an important role in managing and handling the competition. Furthermore a sound product strategy will be prudent for exemplifying the path of success for Mintel. Now in the context of the study the target group of the company is the family unit, thus in order to cater to that section the product strategy is vital. The study also reveals that among 181 people, who are living with a partner, 33 % respondents are highly aware of food security. Similarly among the married people 31% of them have high concerns and 47 % have average concern over the food hygiene. Therefore based on the available data, it is highly recommended that the company should only sell hygiene and fresh foods, which will also help them to build an unique selling proposition (USP). Price Recommendation In open words price is the amoun t paid by the customer for gaining the ownership of a product from the seller (Kotler and Armstrong 282). Although the concept of price is very simple, but when it comes to in truth value a product or service the notion does not exactly remain the same. A pricing strategy is defined as a course of action or an approach in order to achieve the marketing objectives of the company (Pride and Ferrell 318). Hence pricing strategy is crucial towards the acceptance of the product or service in the market plac

Independent Basis Service Set or IBSS Essay Example for Free

breakaway Basis receipts Set or IBSS EssayIndependent Basis Service Set or IBSS is the most radical wireless local atomic number 18a network topology. Sometimes IBSS is also c completelyed an Ad Hoc Network. The IBSS is a form of WLAN network topology wherein the set of stations are being recognized by each of the stations. They are connected by the use of a wireless media in a fashion of peer-to-peer. In an Independent Basis Service Set topology, there is a direct communication amidst the mobile stations. There is a limitation in the communication between a mobile station to the each and other mobile stations because of the limitations in range. Relay functions are not present in an IBSS topology, so all the mobile stations that are connected should be within the range to be able to communicate properly (FallsConnect. com, 2007). Another Wireless LAN topology is the Infrastructure prefatory Service Set. The component of the IBSS is termed as an access point (AP). The role of the access point in the Infrastructure BSS is to supply relay functions for the good basic service set. Communication in the entire BSS is already do in the local points and direct communication is longer occurring.Relay of frames are do by the access points between the mobile stations. The relay function of the access point is effective and efficient in doubling the rage of the Infrastructure Basic Server Set. The access point of the Infrastructure Basic Service Set is also able to offer a bond or a connexion that will be linked to the auction pitch formation. The scattering system is also considered as the strength of character of the wireless local area network. The distribution system is the one which provides communication in an access point with other access points.The communication goals are to replace frames for the stations in their basic server set, to produce frames to pursue mobile stations as they move from one basic server set to another basic server set. S wapping over of frames to with a outfit network is also a goal of the communication in the distribution system (FallsConnect. com, 2007). IEEE 802. 11 gave distribution system a definition that it may either be wired network similar to the 803. 2 or a special point box wherein interconnection of the access points and supply of required distribution services is given.There is a creation of an extension of the mobility range to an arbitrary range. And this is made manageable by the 802. 11 by using the Extended Service Set. Extended Service Set is a set of communication for the basic server set. This is where the access points are able to communicate within themselves. Facilitation of movement from a station to the other station of the basic server set is the goal of the access points communication with other access points (US Robotics, 2007). The determination of a employment done that was forwarded to the basic server set is being identified by the distribution system.The determ ination and evaluation of the traffic if it should be communicated back to the destination where it came from or if the traffic should be promoted to other access points are some of the roles of the distribution system. price of admission points have been able to transmit communication to the mobile station. This communication was made possible by the use of distribution system. The communication transmitted will be received immediately by the mobile station. The hit MAC Layer is still of the extended set server.Another composition of the MAC layer network are the mobile stations outside the extended server set. In the single MAC Layer network, all of the work stations are immobile. Network equipments outside the extended server set is not allowed to have mobility unless they are inner the extended server set. These kinds of indirection equipped with the 182. 11 architecture permits other network protocol outside the extended server set to operate properly in the wireless local area network where mobility is available and present (US Robotics, 2007).The info link layer of the Ethernet Local Area Network system was derived from the Medium Access Control protocol. The Media Access Control protocol is the one which summarizes a SDU. Carrier-Sense Multiple Access with Collision Avoidance is the shared wireless media. This is where the MAC Layer offers controlled access. It is unremarkably like the impact detection access method of the 802. 3 Ethernet Local Area Network. The summary is started with the addition of a 14 byte header before the data and after the data there will also be an addition of a 4 byte (32 bit).The 14 byte header is the Protocol Control Information plot the 4 byte is the Cyclic Redundancy Check. Reliable data delivery for the upper layers is being provided by the IEEE 182. 11 MAC Layer. 802. 11 MAC Layer provides hostage and privacy services to the delivery of the data. Services like authentications offer security together Wireless Equ ivalent Privacy. The Wireless Equivalent Privacy is the data delivery encryption service for the wireless local area network.

Working Effectively in the Aviation Industry with Aborigines

workings Effectively in the Aviation Industry with AboriginesWorking Effectively in the Aviation Industry with Aborigines in AustraliaAs the strain industry in Australia is ever growing, its grandness is also due to the fact that Australia is find on an island. This means that air, along with the shipping industry, provides the only means of connection to the rest of the world. Around 16 million passengers come to Australia formly and 90% of them become through air. The total number of licensed pilots in Australia now are most thirty thousand six hundred and seventy six with roughly one thousand seven hundred licensed helicopter pilots. The Australian Transport Safety Bureau (ATSB) is responsible for the safety of aircrafts and passengers and to everywherelook the entire aviation industry.All institutions are based on their professional elaborations which are formed by different people who form the basis of that industry. The Australian aviation remains is formed by people of different ethnicities and backgrounds. Like any other industry, its professional culture is heavily affected by Australias depicted object culture. Starting from the primaeval Australians to the modern-day immigrants, all form the basis of Australias aviation industry.While institutional racism is prevalent in Australia, this practice in the aviation industry is oft less common. ( run away and racism in Australia, 1988). Institutional racism refers to the way beliefs are incorporated in the social system that results in discrimination against a legitimate minority group. It also includes any activity words or actions that may be derogatory to a certain group of people. (Its just how youve been brought up An native Australian perspective on the relationship between the law, racism and mental health, 2001). Often times, institutional racism is covert or even unrecognized by the agents involve in it. Like every other workplace, institutional racism against aborigines in Austr alia is an important issue. At the same time, some writers may be biased somewhat the role of aborigines in aviation industry, rendering them as formless, transitory, and today undefinable in character. (Local Group Composition Among the Australian Aborigines A Critique of the Evidence From Fieldwork Conducted Since 1930, 1970). some other point that they raise is that aborigines are not fond of adapting to the new system. They would rather not work in an environment where they have to adapt. There is also a communication gap, which makes it difficult for the aborigines to adjust.Despite the popular trend and literary proofs, it has been observed that racism in Australia is within bounds. Aborigines along with other ethnic groups are inclined a fair chance to play effective roles at every organizational level. While there may be a communication gap, the importance of teamwork is recognized by all groups and applied at every level. It is well recognized and understood by all emplo yees that the basis of their organization lies in the teamwork and unwashed respect of every individual. The main job of the aviation industry is to facilitate their passengers and ensure their safety and to take them to their respective destinations notwithstanding their differences in class, caste and pecuniary status. It is said that the safety and efficacy of the aviation industry is based on three cultures, its national, professional and organizational culture and all three shape how the aviation industry performs nationally and globally. (Helmreich, 1998.)For any organization to excel, it must overtake its cultural tendencies that are hindering its progress and strive to work effectively in a team-based environment. It is essential to recognize that everyone has their own designated roles in an organization. Like how a pyramid cannot stand without its base, an organization cannot stand without its employees. This is why the aviation industry in Australia is blooming. Becau se despite their differences they realize that they have a single goal.My experience in communicating and working with people from different ethnic backgrounds has always been positive. Since it has only been my first year as an aviation student, I have yet to have the opportunity to work alongside an Aboriginal person.However, the followers is an example of how I think culture can affect communication effectiveness and the hazards that can happen as a result. During the stall-training lesson of my flight training, I was heading back towards Parafield Airport with my instructor, who is an Australian national without an Aboriginal background. I decided to use the Torrens Island Power Station as a reference point towards Parafield and fly into its direction. Shortly before passing over the power station, the instructor quickly instructed me to change my heading and diverted the aircraft south of the power station. After the flight, I was reprimanded for inducing the potential to dama ge the aircraft. It was at that point, I learnt that the exhaust of the power station had the potential to damage the aircrafts airframe, or even worse cause the aircraft to disintegrate mid-air. If that had occurred, the results would be disastrous with the debris of the plane falling down and causing great damage to Outer Harbor. Had I disregarded my instructors judgment, I may have caused massive damage to Outer Harbor with my aircraft. In the aviation industry, safety always comes first. If a pilot disregards safety in his or her judgment, disaster and casualties occur. This also shows the importance of communication and why effective communication theory is absolutely necessary in aviation industry. A small case of miscommunication may have hazardous impact, ranging from the bursting of the aircraft to causing damage to heavily crowded places, leading(a) to loss of lives in both cases.This also creates hurdles for Thai people like myself who are not upfront about the problem s and hesitate to talk to their seniors about problems. Thais generally like to be on top of their games and would rather not ask questions and lose face in front of their seniors. This may cause a huge communication gap, like in the example above. Had I not talked to my senior about the problem, we may have caused huge damage to the harbor.So far, I havent worked with anyone from aboriginal background. But I would love to experience working with them. Although we may experience some communication gaps, we share a similar goal excelling in the service we provide to passengers and ensuring safety for the aircraft, passengers and crew that are aboard. With this in mind, we can work and learn from each other.Safety has been IATAs number one priority and they advance aviation the industry to take all steps to ensure safety of all people involved in the aviation industry. A study make in New Zealand shows that pilots regard luck as an important factor in the safety of the aircraft (Gil l, 2004). I however think that effective communication skills and following SOP guidelines is more important than just good luck. Another study has been done to measure safety in high reliability organizations (HROs) using the tralatitious measures of incident and accident reporting during periods of deliberate organizational change (Lofquist, 2010). This also encourages the promotion of healthy environment and importance of team work, and how effective teamwork can overcome all sorts of hurdles, may it be language barriers or communication gaps.ReferencesBirdsell, J.B., 1970.

Human African Trypanosomiasis Treatment

Human African Trypanosomiasis wordTHE synthesis of story hydraz unrivaled raises to determine the possible anti-parasitic properties and efficacy in the sermon of Human African Trypanosomiasis.ABSTRACTHuman African Trypanosomiasis is ca practised by two sub-species of trypanosome, Trypanosoma brucei gambiense and Trypanosoma brucei rhodeisense. The protozoan hirudinean has complex mechanisms to evade immune destruction and hence survives in the host, leading to eventual death without intercession. Treatment such as Suramin and Melarsoprol memberic number 18 limited and have high toxicity, often leading to further complications. Alternative therapies are drastic on the wholey needed to combat trypanosomal infection, with saucy hydrazone compounds currently in development promoting trypanocidal action mechanism. The aims and objectives of this research project involve the synthesis of newfangled hydrazone compounds, with aims of high efficacy and miserable toxicity, vi delicet against Trypanosoma brucei rhodesiense. This was achieved through a series of reactions, with proton NMR spectra used to confirm the structures of novel hydrazone compounds, and biological screening analysis used to assess the trypanocidal action mechanism in vitro. IC50 place were obtained for all hydrazones synthesized, the best results coming from HD1, 9.29 M, and HD6, 16.18 M. Overall, the presence of centilitre in the compound typically humbleered trypanocidal activity when compared to HD1, which lacked chlorine atoms. in spite of opposite compounds in lit having much wiped out(p)er IC50 set, the results remain promising, demonstrating trypanocidal activity against T. brucei brucei, the infective form of trypanosome that affects animals. Trypanocidal activity against Trypanosoma brucei brucei suggests potential activity against Trypanosoma brucei rhodesiense, signifying the IC50 values obtained from novel hydrazones. Furthermore, the biological properties of hyd razone structures set up the potential to develop additional analogues and derivatives, which could contribute to combatting Trypanosoma brucei rhodesiense infection. Likewise, alternative therapies that can cross the melodic dividing line-brain-barrier are another interest regarding research in the field. Trypanosoma brucei rhodesiense proceeds rapidly once an respective(prenominal) has been exposed to the parazoan, with severe side effects and high mortality rates. This reinforces the need for better and more effective treatment and management of the disease.Key words Trypanosomiasis, Trypanosoma brucei rhodesiense, hydrazone, Suramin, Melarsoprol, proton NMR, IC50 values1.1. Background of Human African TrypanosomiasisHuman African Trypanosomiasis ( get into), or African sleeping sickness, is a disease affecting a large proportion of Africa, with a suspected 60 million people at risk (Kennedy, 2013).It is caused by two subspecies of trypanosome, a unicellular and flagellated protozoan poriferan, with Trypanosoma brucei rhodesiense (T.b.r) causing East- African sleeping sickness, and Trypanosoma brucei gambiense (T.b.g) causing West-African sleeping sickness. West African sleeping sickness is much more prevalent in foothold of the whole continent, with 6228 cases reported in 2013. Incidence has decreased massively since 2000, with 25,865 reported cases, although this figure is suspected to be higher due to unreported disease incidence. It is the causative sub-species in 98% of cases. The other 2% of cases are classified as East-African sleeping sickness, with 86 cases reported in 2013, approximately 88% swallow than in 2000 (709 cases reported) (Franco et al., 2014). Despite the low incidence of T.b.r infection, symptoms are severe and death expires in almost all patients without treatment. Treatment for suchinfections are limited and have high toxicity, signifying the need for development.Transmission of the protozoan parasite is via the vector, the tsetse fly. Infections with T.b.r proceed rapidly, with entry of infectious metacyclic trypomastigotes into the human bloodstream, lymphatic system and cerebrospinal fluid (CSF) following the initial bite, where proliferation occurs. The tsetse fly ingests a blood meal from an infected animal, with cattle and ungulates acting as reservoirs (Palmer Wells, 2012), and hence ingests trypomastigotes. Various cell divisions and binary fission occur in the mid-gut of the fly to form procyclic trypomastigotes, and conformational changes occur to allow the trypomastigotes to bind to the salivary epithelia. Once attached, the parasite can once again replicate via asymmetric division (Pepin, 2014) to form metacyclic trypanosomes. It is in this way that a person becomes infected with T.b.r (Langousis Hill, 2014).1.2. ImmunologyThe causative parasite manifests in hosts due to the evasion of the immune system through antigenic variation, delaying the immune response and therefore allowing the parasite to complete its complex lifecycle (Stijlemans et al., 2016). The parasite expresses variant surface glycoproteins (VSGs) on its cell membrane via a glycophosphatidylinositol anchor to serve as a protective barrier. plot the immune response induces antibody development against the VSG macrocosm expressed, the parasite can switch VSG due to the large amount of VSG genes the genome possesses. This causes unsanded antibodies to form against the newly expressed VSG, and the parasite continues to change VSGs to avoid destruction. Furthermore, the parasites alter their energy metabolism and internal structure, presenting further issues for the immune system (Stijlemans et al., 2016). T.b.r. is resistant to human trypanosome lytic factors (TLFs) containing apolipoprotein L1 (ApoL1), and this is due to the existence of the serum protection protein (SRP) coded for by the SRA gene. This binds to TLF-1 and therefore prevents ApoL1-mediated lysis of the infected parasitic cells (Ken nedy, 2013 Bart et al., 2015).Kato et al. noted the upregulation of certain cytokines following T.b.r infection, namely IFN-, IL-10, IL-6 and TGF- (Kato et al. 2015). Furthermore, these cytokines whitethorn play a key role in the inflammatory immune response. IL-6 and IL-10 were upregulated upon CSF examination of late stage patients, and those with CSF trypanosomes had higher levels of WBCs, positively correlating with IL-6 CSF levels. Despite this, no significant changes in levels of cytokines at different stages in HAT were noted.Both subspecies of trypanosome cause non-specific inflammatory responses, resulting in non-specific symptoms. This demonstrates the difficulty in diagnosis and staging of T.b.r infection, and therefore poses a hindrance in regards to timely treatment (Lamour et al. 2015).1.3. SymptomsSymptoms, typically manifesting 1-3 weeks after bite, include myalgia, hyperplasia of the lymph nodes and spleen, and weight loss in the haemolymphatic stage, and there is clear central nervous system (CNS) involvement in later stages (Pepin, 2014 Kennedy, 2013). It is in this meningoencephalitic stage where patients often exhibit behavioural and motor disturbances including tremors, speech complications, anxiety, confusion, personality changes and others. Further complications whitethorn manifest, including ocular difficulties, acute renal failure, multi-organ failure and chronic lymphocytic meningoencephalitis. Death is passing likely to occur in those who do not receive treatment. Trypanosoma brucei produces an aromatic compound called tryptophol, and this induces sleep in humans. Other complications with sleep include irregular patterns of sleep or interrupted sleep, insomnia during the night and sleepiness during the daytime.1.4. Current problemCurrent pharmaceutical treatment including intravenous Suramin or Melarsoprol is ineffective and potentially toxic, with patients suffering with neurological dysfunction and post- treatment reactive encep halopathy. Co-administration with eflornithine and nifurtimox has been used to treat T.b.r infection also, but remains close to ineffective.Suramin is provided intravenously as the first line treatment for the haemolymphatic stage of T.b.r infection, however this treatment can lead to side effects such as renal failure, peripheral neuropathy and anaphylactic shock, amongst others. It acts by stick to enzymes in the glycosome and disrupts glycolysis within the trypanosome (Babokhov et al., 2013). Should the parasite cross the blood-brain barrier in the later stages of the disease, the treatment options are toxic and limited to the arsenic compound, Melarsoprol, which acts by disrupting trypanosomal redox mechanisms. Treatment with this can lead to further complications such as post-treatment reactive encephalopathy seen in 10% of patients (Palmer Wells, 2012), subsequently causing comas, seizures and cerebral oedema for example.Co-administration of eflornithine with nifurtimox, a hydrazone of 5-nitro-2-furaldehyde, has been shown to demonstrate trypanocidal activity, and is routinely used to treat T.b.g. It has shown trypanocidal activity against T.b.b in mice, however has been relatively ineffective against T.b.r. Furthermore, although eflourthrine abides Lipinskis hold of five dollar bill in theory, in practice it is a highly hydrophobic compound, and is therefore unlikely to cross inner membranes once administered (Gilbert, 2014). It is therefore administered intravenously.Due to there being no self-cure for T.b.r, treatment is required for a recovery to be made. Furthermore, m every(prenominal) of the drugs developed are only applicable to bloodstream trypomastigotes, rather than those that have crossed the blood-brain barrier (Palmer Wells, 2012). Factors such as this demonstrate the elusive nature of the disease, as well as the need for alternative therapies to combat the infection.1.5. Current researchCurrently, novel treatments are in developmen t with the hope that toxicity is reduced and efficacy is outgrowthd against trypanosomal parasites, namely T.b.r and T.b.b. To determine whether a proposed therapeutic compound is likely to be membrane permeable and therefore orally bioavailable, the Lipinskis rule of 5 is applied. To be within the limits of the rule means that the compound is orally bioavailable and easily absorbed by the body (Leeson, P. 2012). The rules state that the molecular weight of the compound must be little than 500 Daltons, the lipophilicity value is less than 5, represented as a LogP value, the number of hydrogen bond acceptors must be less than 10, and the number of hydrogen donators must be less than 5. Hydrogen bond acceptors include highly electronegative atoms not bound to a hydrogen atom and with free electrons on its outer shell, including oxygen and nitrogen. In newer literature, fluorine may be considered and counted as a hydrogen acceptor. This contrasts with a hydrogen bond donor, any atom that donates a hydrogen atom that it is bound to break or form a bond. All novel compounds are assessed under these rules to determine properties snarly in pharmacokinetics ( preoccupation, distribution, metabolism and excretion). Oral administration is non-invasive, more bioavailable and simpler for patient use, all of which is desirable for a new treatment for T.b.r infection. Furthermore, a compound designed may still be orally bioavailable if a single rule is not adhered to.Benzoxaborole compounds have recently been suggested as a new, novel treatment for Trypanosoma brucei (T.b.r and T.b.g) in vitro, namely SCYX-7158 oxaborole(Jacobs et al., 2011). The orally-active treatment is suggested to have high efficacy for both acute and chronic stages of the disease due to the treatment being permeable to the CNS, and properties such as distribution, metabolism, elimination, absorption and toxicology are apparent in vitro. A viability assay combined different whole cell T. brucei spp .and the novel compound to gain positive results of anti-parasitic activity. This treatment exhibit concentration-dependency, and most trypanocidal activity came from the first 8 hours of a 24-hour exposure. Furthermore, the irreversibility of trypanocidal activity was noted during a short exposure. In vivo, SCYX-7158 was examined against an infection with T.b.b to monitor passage across the blood-brain barrier, with mice models providing an 80% cure rate over a 7 day-treatment. Benzoxaboroles, like hydrazones, have demonstrated anti-cancer, anti-fungal, anti- bacterial, anti-viral, anti-inflammatory and anti-parasitic properties with a low intrinsic toxicity similar to instrument panel salt when decomposed (Liu et al., 2014). This is due to the metabolites of benzoxaboroles being found to be boric acid and oxidative deboronation products, both with very low toxicity. Per Lipinskis law, it is an orally bioavailable drug with very low IC50 values ranging from 0.19 to 1.008 M, demon strating high trypanocidal activity in vitro. An IC50 value is value is the inhibitory concentration value at which 50% inhibition of target cells has occurred. It is important when analyze the difference in the potency of compounds. A higher value represents less efficacy, with smaller values representing good trypanocidal activity in this case. It is a pharmacokinetic parameter, measuring the kind between drug target and drug.Other research at the forefront include the development of hydrazone compounds of 5-nitro-2-furaldehyde and adamantine alkanohydrazine (Foscolos et al., 2016). Adamantine and derivatives have been previously shown to have trypanocidal activity, increase for the more hydrophobic, phenyl and cyclohexyl substituents. These compounds and derivatives demonstrated good trypanocidal activity, approximately 20 times greater than nifurtimox. The lowest IC50 value obtained was 0.386 M. Following the same study, it was found that in the absence of the nitro group, no trypanocidal activity was demonstrated, highlighting the trypanosomal nitro reductase mechanism these novel compounds work by. In terms of the structure-activity relationship, it was seen that the selectivity of compounds against T. brucei species increased when the distance between the carbonyl group and the adamantine skeleton was increased, with derivatives containing 3-cyclopentyl and 3-phenyl being more biologically active than other compounds. In conjunction, the lipophilicity and conformational structure contributed to the efficacy of these novel compounds, with increased lipophilicity and conformational flexibility promoting trypanocidal activity.1.6. Aims of researchBetter pharmaceutical treatments with high efficacy and less lethal side-effects are drastically needed for T.b.r infection. Current research demonstrates the potential use of hydrazone compounds and derivatives in combatting parasitic infections, amongst others. Guidance from project supervisor Dr A Bhambra was exitn throughout the project regarding the structures of compounds. Hydrazones are defined as having the structure R1R2C = NNH2, the N=H bond is conjugated with a lone pair of electrons on the functional nitrogen atom (Verma et al. 2014). Research suggests hydrazone compounds also demonstrate anticancer, anti-inflammatory and anti-HIV properties, signifying biological variety and the potential to treat other diseases (Verma et al., 2014). It is because of these properties that new hydrazone compounds are in development, with the aim of synthesising novel compounds which demonstrate similar properties when applied against Trypanosoma brucei infection, and hence a potential therapeutic for T.b.r.2.1. Chemistry/ experimental synthesisThe synthesis of four novel hydrazone compounds of reactants A-D and Pentafluorophenyl hydrazine (PFH) (Figure 3) was performed. All consequences and reactants were commercially available. Reflux condensation reactions with relevant reactant (3 mmol) an d PFH (3 mmol) were performed, with continuous heating (oil bath) and stirring of compounds at 100-150 C approximately. Compounds were separated with ethyl acetate (60 ml) and distilled water (50 ml). dissipation magnesium sulphate was added to remove any excess water and products were vacuum filtered. Recrystallization reactions with boiling ethanol (10 ml approximately) not in excess were performed, and compounds were vacuumed down to give final compounds. Thin Layer Chromatography (TLC) analysis was performed for all compounds throughout the stages of experiment to monitor the constituents of the final product. Prior to NMR analysis, compounds were dissolved in chloroform (800 L) with expulsion of HD6 (with reactant D), dissolved in DMSO (400 L).2.2. Biological Screening AnalysisFurther viability tests were carried out to assess the trypanocidal activity of each compound. Compounds were sent to the London School of Tropical treat for biological screening analysis against T.b.b . Stock drug solutions were prepared in DMSO at 20 mg/ml and further diluted permitly. All assays were performed with use of 96-well microtiter plates, each well containing 100 L of parasite culture, and serial dilutions of the compound in triplicate. Wells were incubated at 37C for 72 hrs in 5% CO2. Control wells contained no compound, and blanks consisted of medium only. Following this, the MIC was determined and assurance of growth in control wells. 20 L of Alamar Blue was added to wells, and plates were incubated for 2-4 hrs more. Plates were read on Gemini Plate Reader with an excitation wavelength of 530 nm and emission wavelength of 580 nm. Following this, IC50 values were obtained.Four novel hydrazone compounds were synthesised, shown in table 1. The electrophilic carbonyl group of countenance reactants A-D reacted with the nucleophilic nitrogen (hydrazine portion) of PFH by nucleophilic addition. IC50 values gained demonstrated potential, especially HD1 and HD6. Proton NM R analytical results from spectra obtained are demonstrated below, showing the amount of hydrogens (or protons) in each compound as well as their corresponding intensities. Throughout synthesis, TLC was performed for each compound to visualize the two reactants, the formed product and any other substance that may be present. Rf values and appropriate TLC analysis results are illustrated in alongside compounds in table 1.3.1.

Biological screening analysisResults obtained from the London School of Tropical Medicine included IC50 values for all hydrazones synthesised. These are listed alongside appropriate comp ounds in table 1. HD1 had an IC50 value of 9.29 M HD4 34.37 M HD5 34.09 M and HD6 16.18 M.Formation of all compounds HD1, HD4, HD5 and HD6 (table 1) followed the general mechanism illustrated in appendix 1. R1 should be substituted with relevant reactant (A-D) benzol rings. Electrophilic reactants accept free pairs of electrons from the nucleophilic nitrogen atom of PFH by nucleophilic addition. The formation of a biologically active centre was documented (Verma, 2014). All compounds synthesised contain phenyl groups, which has been suggested in literature to promote trypanocidal activity (Foscolos et al., 2016). Hydrazones synthesised are also non-polar and hydrophobic compounds, meaning that they carry no net charge and are not soluble in water. Furthermore, an increase in hydrophobicity also promotes trypanocidal activity, however has been suggested to make the compound less bioavailable (Gilbert et al., 2014).Proton NMR spectra demonstrate relative intensities in parts per mill ion (ppm) of protons or hydrogens in the compound. Despite only hydrogens being of interest, it is important to consider the other electronegative groups that exist within the compound such as phenyl groups or -OH groups, which produce different peaks. The solvent peak demonstrates as a sharp, well distinguished peak to exclude it from the compound results. Singlet, doublet andNameReactantStructureIC50 value (M)TLC (illustrated- not to scale)Rf value (cm) HD1Benzaldehyde (reactant A)9.290.73HD43-chlorobenzaldehyde (reactant B)34.370.48HD54-chlorobenzaldehyde (reactant C)34.090.43HD63,4-dichlorobenzaldehyde (reactant D)16.420.57 multiplet peaks were all demonstrated on the spectra. NMR analysis reflects the structures synthesised, confirming the number and positioning of hydrogens. The spectra observed demonstrated some sharp peaks and others more broad. Furthermore, some peaks were somewhat distorted due to the presence of chlorine on the aromatic benzene ring.Limitations of the exp erimental synthesis included low yields obtained from synthesised hydrazones. This could have been possibly due to the recrystallization amount or some of the reactants not converting into product. Factors such as this could have been improved to gain better results. In addition, yields were estimated due to not advisement compounds beforehand, therefore weighing the compounds when they were initially synthesised would improve the data.4.1. HD1From the NMR spectra, HD1 contained 7 hydrogen atoms, one at 7.28 ppm as a singlet peak, three at 7.32 7.42 ppm as a mutliplet peak, two at 7.64 ppm as a doublet peak and one hydrogen at 7.82 ppm as a singlet peak. All novel compounds synthesised differ in terms of the aromatic benzene ring on the relevant reactants, therefore the positioning and amount of chlorine attached to this aromatic ring demonstrates the difference in IC50 values. This coincides with the biological activity against T.b.b. HD1 is formed of benzaldehyde and PFH, and t herefore does not possess any chlorine atoms. The IC50 values were the lowest for HD1 at 9.29M, which suggests that the presence of chlorine in the compound may decrease trypanocidal activity.4.2. HD4HD4 contained six hydrogen atoms, two at 7.30 ppm as a singlet peak, one hydrogen at 7.35 ppm as a singlet peak, one hydrogen at 7.45-7.50 ppm as a multiplet peak and a one hydrogen as a singlet peak at 7.73 ppm. HD4 contained a chlorine group on the 3rd carbon of the reactant benzene ring, with displacement of chlorine by (bio)nucleophiles, facilitated by the electrophilic carbon centre determining biological properties observed. However, it has been suggested that the presence of a chlorine atom at a non-reactive aromatic double bond diminishes reactivity (Naumann, 2003). The IC50 value for HD4 was 34.37 M, the highest value from all the compounds synthesised. This supports the notion that chlorine atoms present in the compound reduces trypanocidal activity rather than improving it.4. 3. HD5HD5 also contained six hydrogens, with three hydrogens at 7.32 7.38 ppm in a singlet peak, 2 hydrogens at 7.54 7.60 ppm in a doublet peak, and one hydrogen at 7.78 ppm in a multiplet peak. HD5 also contained a chlorine atom but on the forth carbon of the benzene ring, as opposed to the third. Altering the position of the chlorine atom did allow for an improved IC50 value to be obtained, which was 34.09 M. This however remains much less effective than HD1.4.4. HD6HD6 contained five hydrogen atoms, one at 7.37 ppm as a singlet peak, one at 7.35 ppm as a singlet peak, two at 7.45 ppm in a singlet peak, and 2 hydrogens at 7.70 ppm in a singlet peak. Despite the presence of chlorine in both HD4 and HD5 causing less effective activity against T.b.b, HD6 contained two chlorine atoms attached to the benzene ring, and the IC50 value obtained was nearly half that of HD4 and HD5 at 16.18 M. This suggests that the presence of one chlorine atom existing at any carbon on the benzene ring does not promote trypanocidal activity, however the presence of 2 attached chlorine atoms did aid activity.4.5. Oral bioavailabilityPer Lipinskis rule of 5, all novel compounds fall within the laws except from HD1, which contains 6 hydrogen bond donors. HD1 therefore would be more bioavailable if administered intravenously, however may still be orally bioavailable as only one rule has been violated, with the rest all being adhered to. Despite this, the other novel compounds alone demonstrate progression in seeking an orally bioavailable treatment for HAT, linked with reducing toxicity amongst being easier and more accessible for those who require it. Furthermore, the use of PFH incorporates many fluorine atoms, which increases lipophilicity (Citation), increasing activity in vivo, as well as increasing fat solubility and therefore allowing the compounds to easily pass through membranes in the body. Retaining fluorine is a desirable holding due to the improvement of metabolic stabil ity as a result of the high strength C-F bond. It is a relatively small molecule, with a high negativity value. All properties such as this contribute to biological responses within the body.4.6. Comparison to literature IC50 valuesHD1 and HD6 demonstrated the most promising results of 9.29 and 16.18 M. For comparison intentions, alternative novel therapies at the forefront of science such as adamantine alkanohydrazine hydrazones and benzoxaborole SCYX-7158 have IC50 values of 0.386M and 0.19 to 1.008M respectively (Foscolos et al., 2016 Jacobs et al., 2011). Although the results from the synthesised compounds are promising and suggest trypanocidal activity against Trypanosoma brucei, both SCYX-7158 and the adamantine alkanohydrazine hydrazones have much lower IC50 values, suggesting that the structures of novel compounds could be improved and altered to gain better trypanocidal activity. Furthermore, current treatment Melarsoprol and Suramin have IC50 values of 0.046 and 0.004-0.0 09 M, much lower than the compounds synthesised (Torreele et al., 2010). However, as stated above, these treatments offer high toxicity and high mortality rates following administration, and the fact that the novel compounds synthesised (HD1 especially) have low IC50 values remains promising. Furthermore, both Suramin and Melarsoprol are administered intravenously, posing more problems in terms of accessibility as developing countries where the disease is endemic possibly do not possess the facilities to administer treatment. This is unlike the synthesised hydrazone compounds, which all theoretically can be administered orally, therefore moving towards better treatment and management of T.b.r infection.HD4 and HD5 demonstrate lower trypanocidal activity than HD1 and HD6, therefore further progression on HD1 especially would allow for potentially more effective trypanocidal compounds, represented by lower IC50 values upon testing. Furthermore, new compounds in other literature with t he highest trypanocidal activity, namely 5-nitro-2-furaldehyde and adamantine alkanohydrazine hydrazones and benzoxaboroles, provide a platform for future work and development of structural analogues of hydrazones to promote trypanocidal activity.To confirm that the novel compounds synthesised are in fact effective against T.b.r, further testing is required in a controlled level 3 laboratory where the p

Effect of Reader Schemes and Initiatives on Child Reading

Effect of Reader Schemes and Initiatives on Child ReadingInvestigate whether the deepen Reader Scheme and Star Reader Test has a positive effect on a childs variant execution.AbstractAn rating carried off in a primary school on the implementation of the deepen Reader Scheme manifests its efficacy in improving recital hit and recitation dayss for students who atomic number 18 less able readers. The books review shows that epoch there is limited secern on the scheme itself, which is derived from American schools settings, there is evidence which shows that similar schemes, which atomic number 18 targeted on reading development, and similarly schemes which integrate ongoing take and feedback (either individual(prenominal) or ICT base) argon impelling in bideing those who atomic number 18 falling behind national literacy standards. However, this report card, which utilises marks and reading scores to evaluate the scheme, is limited in its applic readiness and i n the usefulness of its findings. More re calculate is postulate into the underlying cultures and pedagogies which affect such reading interventions, and much(prenominal)(prenominal) depth and detail of pupil attitudes and responses are required to go steady how such programmes affect student achievement in reading and in the longer term.IntroductionChildrens reading development is a key feature of overall literacy in the primary age company, and as such is subject to considerable governmental governance and input. Achieving standardised levels of literacy is seen as cardinal in ensuring children reach developmental and cognitive milest mavins, and are decent prepared for standby school when they move into this phase of their education. However, there are a number of challenges to supporting children to read, because even though this is a key fraction of their learning, children are a good deal lacking in enthusiasm or confidence about reading, and do non take sanitary to reading for pleasure. Similarly, school resources often mean that support for reading is less than optimal, particularly if teachers do not have enough time to devote to listening to children read and providing them with feedback and guidance.This dissertation describes an valuation of a new approach to improving literacy in a chosen age group inwardly a primary education setting the deepen Reader Scheme, which includes the Star Reader Test. This scheme uses figurer-based resources to encourage children to read. Children take the Star Reader test, are assigned a reading age, and then are pointed to books associated with that reading age within the school library. Children read the books and then take comprehension tests, which demonstrate their level of learning and their rise. Students can access the website at Think.com to graph their progress and see their own growth. The scheme originated in America, where its success within primary age schools was demonstrated, and has since been adopted in a number of schools in the join Kingdom. There is some literature to cite the benefits of the Accelerated Reader scheme, and a lot of examples of websites, weblogs and feedback demonstrating enthusiastic approaches to it in certain schools and locations.This dissertation shows an evaluation of this scheme in wizard school setting in a socio-economically deprived area, and contains primary data on the implementation and effects of the scheme. A critical review of the literature was carried out, to explore the condition of the scheme and its place within the pedagogy and practice of primary education within this country. The discussion of the scheme and its results takes into account current surmise, and concludes with recommendations for prox research and practice. A summary judgement of the efficacy of the scheme is included. The evaluation is based on reading result scores as discussed in the findings sections, and indicates where the scheme has been effe ctive, and where findings were comprise to be other than those anticipated. The conclusions make recommendations for future research surrounding this intervention, and also explore some of the drawbacks of utilize such an approach.Literature retrospect see StrategyA critical review of the available literature was carried out, in order to set the context of the study and evaluation, and to explore the current state of theory and practice. A literature search was first carried out, in order to identify the pertinent literature which could be employ to inform the study. In order to do this, the root first carried out a thought shower in order to identify key basis to be used as search words and search word combinations, then used these to search the literature, shortlist articles by abstract, and then select full text articles for reading and review.The Critical ReviewThe changing character of education, particularly within the state-funded sector, is such that there are emergent issues around the ways in which educational goals are defined and set, and the context of education1. However, the concern of this dissertation is the effectiveness of interventions in relation to supporting reading competence in primary schools, and so the focus of the literature review is on reading competence, reading interventions, and factors which efficacy affect reading and the success of such interventions. It was decided to take a broader approach to the literature review because there were rattling few primary studies which directly assessed Accelerated Reader itself, and therefore the understanding of the current theoretical and practical context needed to be explored in terms of this type of approach to reading competence.The literature demonstrates that there are m both factors which may affect childrens reading abilities and progress2, not all of which are inevitably to do with the childs cognitive or other abilities3. Understanding these factors may be important in understanding the kinds of schemes and programmes which might support reading progress in all children4. This review does not detailally address children with Special Educational Needs provided does make some mention of them in relation to inclusive schools practices. Although published data presented by governmental and other official sources suggests that there have been meaningful cleansements in reading and literacy overall in children in primary education, there are other authors who argue that this is not the case, and the tests and measured used have been advantageously designed to reflect better on the current ruling party and its policies5. While standards may be improving, it is suggested that these improvements are not as significant as they are claimed to be6, 7, and that recording and testing processes are sufficiently biased to warrant an independent body be set up to monitor standards8.The introduction of the National Literacy Strategy may have something to do with changing responses to reading and even changing attitudes to reading, but this does not mean that the responses are overwhelmingly positive. One study suggests that the ways that children interact with reading and with books, and their attitudes towards books, are much more complex than the official guidelines and strategies might suggest9. This study was a questionnaire study with a sample of 5076 pupils in Years 4 and 6, and instal that attitudes towards reading, while generally positive, did appear to decline between the younger and older of the sampled age groups10. Of the overall sample, it seems sub-sample of 2364 of these pupils were actually in the same schools where the same questionnaire had been implemented previously, in 1998, and it was set in motion from comparison of these two incidences that consumption of reading had significantly fallen over the five eld, whilst confidence as readers had significantly sum upd over the same stop11. It may be that these ch anges may have something to do with the introduction of the National Literacy Strategy, but it is argued that other, less popular explanations are also possible for this change, including differences in cordial life and differences in childrens exposure to other media and other forms of entertainment12. What is interesting about this study is that children were enjoying reading less, but had more confidence in reading. This might reflect the outcomes based type of education that is now very much the standard with the UK context, and to this author, also reflects the fact that reading literacy is very much related to competence rather than true enjoyment of texts and of wider opportunities for reading. This might also represent a restriction of students to only reading set books or texts, perhaps, which would possibly limit enjoyment and pleasure in reading.Strategies towards improving literacy have taken many forms, but on significant change has been the use of classroom assistant s, who specifically target reading and other deficits in children in general classroom settings. Interventions to provide extra support through classroom assistants have been shown to improve standards at Key format 1 testing13. However, studies such as these on meeting national standards in literacy do not address the wider and more complex issues around reading and naming of students, and around the pedagogy of literacy direction and the limitations of having standards based education rather than supportive education that encourages children to realise their own potential. Other studies, such as champion carried out recently in Ireland, show that specific programmes, such as the Reading Recovery programme, can be efficacious in improving standards14, but more work needs to be done on evaluating what is described as the depth of such approaches, meaning how they really affect student-teacher interactions and quality of experience15,16.Earl and Maynard explore one potential issu e in relation to reading progress and proficiency, the reluctant reader, looking at what makes children behave in this way17. They examined the underlying reasons for children to develop a negative relationship with reading, and the possible resulting attitudes that they may develop towards it, and found that while the majority of children claimed to enjoy reading, in actuality, they found reading difficult, and subsequent investigation indicated that these children were not confident n their reading abilities18. The study showed that self-efficacy and a sense of autonomy were potential features of improving these responses to reading19. Earl and Maynard conclude that reluctant readers should be offered the opportunity to take office for their own reading practice and development, to allow them to learn for themselves the value of reading20. It was also discovered that it is vital that the childs parents/carers1 are involved with helping to tackle their childrens reluctance to read . enate input is crucial to a childs education if this input is provided at an early stage, then reluctance to read is more likely to be successfully track and may even offer prevention as well as cure (p 163)21.There is some research to suggest that teachers are one of the important factors affecting student outcomes in literacy22. This is not just to do with their ability to use teaching skill in literacy development, but to do with other features of teaching practice.It is teachers expectations, their enacted curriculum, their classroom talk, their relations to young people and their actual ways of inducting them into specific textual practices that most affect literacy outcomes.23This would suggest that while there may be specifics of educational practice, and pupil response or individual ability, there can be things to do with teachers themselves that are as important as paying caution to reading ability. In a study by Wilkinsonit was found that teachers used theory effectiv ely to improve the literacy outcomes of students in eight disadvantaged South Australian schools24. Teachers constructing and using theory to enhance their agency emerged as one of the key factors that made a difference to student outcomes, which can be viewed as teachers using theory to underpin their actions, and achieving positive effect25. It would seem from this study, that teacher quality is predicated on teacher knowledge, particularly theoretical knowledge26. However, this study was carried out in Australia, within a contrasting cultural, pedagogical and policy context, and as such would have to be replicated within a UK context to be fully transferable.Fisher also suggests that there are features of teachers and teaching practice which may affect reading activities and reading attainment27. He also suggests that despite a growing awareness and understand of sociocultural personality of language and classrooms, teachers and theorists are continuing to argue for more freque nt and extended opportunities for teacher-pupil exchanges and discussions about texts, and more reciprocity in teacher-child dialogue in relation to reading and exploring texts and books28. Fisher (suggests that there are studies of classroom teaching practice and activities which demonstrate the continued use of triadic dialogue, in which the teacher predominantly controls the personality and length of any interaction, and effectively closes down discussion rather than support more free exploration and debate29. This would seem to indicate that there is more to students growing reading skills and engaging with reading than simple pedagogical practices and activities, and much of the work around reading is still functional rather than philosophical. However, it may be that these findings precisely reflect the realities of classroom practice, with deliberate control over discussions because of the need to maintain good discipline and achieve the prescribed tasks and goals of the teaching at that point. Certainly a classroom which encouraged more free debate and interaction with teachers could be viewed by some traditionalists as one in which discipline would be harder to maintain. And because of the kinds of limitations on resources, some ideal ways of addressing reading skill might not be practical.A study by Downer (2007) shows that one to one, targeted reading and literacy support, provided by teaching assistants, could be efficacious in improving the reading abilities of pupils who were falling behind literacy standards30. The study showed that as little as four minutes one to one support each day could make a difference31. However, this study is about supporting children identified as having fallen significantly behind their peers and the natioanl standards for their developmental age, and might require resources that are simply not available in the majority of state schools. It also has the disadvantage of singling out the students who are demonstrati ng slower progress and development in reading, which is not necessarily a good thing because it lastlights the difference between them and their peers. Yet it does highlight the potential value of providing targeted reading support, perhaps even 1 to 1 support, in supporting childrens reading.Hatcher et al (2005) report a randomised controlled trial which evaluated the effectiveness of an intervention for reading-delayed children in Year-1 classes32. In this, a sample of 7 children from 14 different schools, children identified as having the curtest reading ability, were randomly allocated to either of the two groups, and the 20 intervention group get the programme for two times ten weeks, the second group only for the second ten weeks33. This was a small group programme, providing daily sessions of around twenty dollar bill minutes, comprising small group and individual teaching34. In this study, the children who received the programme during the first ten weeks made markedly mo re progress on outcome literacy measures, but the children who received the programme in the second 10 week period seemed to catch up with the first group35. This programme, as with that described by Downer (2007), used trained teaching assistants, and found it was effective for children who showed reading delays, although around a quarter of children did not respond to the intervention36. Again, this is an intervention which single out those with less ability and provides specialist input, but it does not really address the notion of reading as a whole within the primary classroom, and, as with the previous study, singles out the poor achievers. This is no surprise, as it really reflects the predominant ideologies of national strategies for literacy37.There are a number of ways of targeting literacy, especially in poor achievers. Bunn (2008) reports a study which compared the progress in reading and spelling of 256 children in eleven classes in nine primary schools in England, loca ted in years 3 and 4, and a partially overlapping sample of 126 children who received additional help with literacy during a single year38. In this study, teachers and teaching assistants implemented either special Literacy take for (ALS), which is a highly structured programme of small group teaching activities and materials, developed by the English National Literacy Strategy, or they used a broad range of other materials and approaches, including other published intervention programmes, reading scheme-based, computer-based and individually designed interventions, alone or in combination with ALS39. A intensiveness of this study is that the researchers explored the influence of a broad range of contextual factors, especially whether childrens qualities, school factors such as socio-economic status and class size, and delivery differences made any marked differences to the results of the different interventions in relation to reading ability40. The design of the study was a natu ralistic quasi-experimental design, and the author found ALS was marginally more effective than other interventions in the majority of the classes studies, however, the authors also found limitations in their ability to catch up to their peers, and found little difference in attainment in relation to individual factors41.another(prenominal) study demonstrates a targeted, home-based intervention that can be good at supporting literacy in children identified as being at risk of developing reading problems42. This was the Literacy Early Action Project, which is described as a home-visiting scheme for these children, carried out by teaching assistants, which involved parents and grandparents43. The study of this intervention identified five key factors which supported the childs progress the flexibility in the teaching assistants approach that enabled extended family members to become sedulous in literacy support the teaching assistants sensitivity to family culture the playful approac h to learning adopted by the teaching assistant putting the child at the centre of the intervention and the existence of a school culture that strongly promoted involvement for parents44. What this shows is that not only do certain children need more support than is available in current school settings, but that the individual needs and attributes of the child are important in achieving reading standards. The nature of the intervention, therefore, must be something that would be responsive and sensitive to individual children.Most literacy support programmes, particularly those for under-achievers, are based on phoneme-oriented strategies45. Authors of one study suggest that training in phoneme awareness and letter-sound knowledge is a fundamental part of effective interventions for poor reading in the context of reading books in particular, and evaluate the UK Early Literacy Support (ELS) programme46. Again, this is a study on children who were already identified as poor readers, a nd found that this programme offered a cost effective method of boosting 6-year-old childrens reading to an medium level47. However, it does not address the idea of improving attitudes towards reading, rather, it focused on functional reading skill. A similar study explored why students did not respond well to phoneme-based reading support, and showed that other factors, such as letter knowledge and vocabulary were important in attaining reading competence48. This study also fails to address issues in the nature of the reading materials that may affect childrens responses to reading activities.Technological advances and the rapid development of information and communications technologies within the leisure as well as the educational sector an have effects on and provide insight into different ways of supporting reading skill development for children. Wood reports a small scale study of beginning readers using a form of talking books software, compared to adult teaching support, usi ng the same books in paper versions49. The authors found that there were no significant differences between the two groups in their phonological awareness attainment, with both groups showing equivalent gains from pre- to post-test. Use of specific features of the software was associated with gains in rhyme detection ability and with changes in the childrens reading strategies50. While this is a small study with a limited sample, and limited transferability, it does show that children might interact slightly differently with ICT-based reading interventions, perhaps due to differences in autonomy and engagement with reading materials, although more research is definitely needed into what features of the ICT-based reading activities are most effective.Another study describes the evaluation of a parent delivered, computer based beginning reading program51. Statistically significant treatment effects were found for Kindergarten students in the intervention group on letter-sound fluency, oral reading fluency, non-word decoding, and phonemic awareness skills. Grade 1 students in the intervention group demonstrated significant improvement over time on letter-sound fluency, letter-name knowledge, non-word decoding and oral reading fluency however, these improvements were not significantly greater than those for the Grade 1 comparison group52. This study was implemented in pupils across the ability range, but the authors also concluded that it might be a very useful intervention for students more at risk of poor achievement in reading and literacy53. It is interesting that this computer-based intervention was particularly targeted at reception and year one age students, and this author would raise the question of how well different reading programmes meet the needs of different ages. Also, it would have been good to have more detail about the computer based programme and its components. This may be a feature of these kinds of studies, that they do not really look at wh at it is about the programme that attracts students or engages them.Another study outlines the use of computer software to identify reading problems and propose ways of addressing these. This is in the form of an adaptive assessment named the Interactive Computerised Assessment organization (InCAS), and can be used with children of a wide age range and differing levels of ability, in order to identify specific reading problems54. There are different potential formats of feedback to teachers, but overall the feedback provided also indicates how children need to improve55. Such programmes may be very useful but it is difficult to see how they can improve on good teacher-student interaction, and whether or not they would help to reduce the major challenges of managing the teaching work load to improve literacy. While it is unsurprising that the programme is aimed at addressing specific reading problems, it also underlines the ongoing theoretical and pedagogical orientation towards eli minating problems rather than enhancing students reading experience, engagement and enjoyment. However, there is research which shows that reading can be raise by ICT-type reading tools and activities56.Reading is important for many reasons, not just for the childs ability to carry out the increasingly difficult tasks which oblige with their progress through school57. Wallace (2008) shows how literacy an identity are strongly linked within the minds and behaviours of children, and how reading can help them to build links and connections between the childrens diverse personal histories and the texts and practices validated by school58. Supporting the development of reading literacy, and also engagement with reading as an activity in itself, may be a more important feature of primary schooling than is suggested by government guidance59 and by teaching practice and pedagogy. It may, perhaps, be more than a functional skill.There are also some differences found within primary educatio n between the genders60,61, 62, and between reading fiction and non fiction independently63. Boys tend to be of lower reading ability than girls, 64, 65, and although they may read marginally more non-fiction than fiction, they appear to do this less carefully and with less skill66. A mixed methods, but primarily ethnographic study in the North of England found that there were two different discourses around reading, both of which were genderedTwo main differently gendered discourses about reading were encountered. The one discourse, dominant in the working class classroom, was strongly gendered and afforded reading low status. The other discourse encountered in the middle class classroom was gender-inclusive and reading carried high status. It is argued that the interaction between social class and gender is important in understanding childrens discourse about reading.67This seems to show that reading ability is based upon a much more complex interaction of factors than simply the child interacting with the set activities, and being defined as a reading age regardless of other features of their life, personality and attitudes. The study also demonstrates the ways in which class and social context affect perceptions of reading and reinforce gender differences in literacy and attainment at this early educational level. How much any reading intervention or teaching approach to redress this balance is debateable.Other research appears to demonstrate that the idea of encouraging reading for pleasure, rather than for necessity68, is not really a part of current pedagogy and classroom practice69, 70. In a study of secondary schools in the south of England, it was found that because of a lack of time and absence of demand for wider reading in the English curriculum, teachers expressed ambivalence about encouraging and assessing wider reading, and teachers with less experience expressed uncertainty about how to introduce and encourage this71. Interestingly, it was al so found that where teachers did initiate wider reading, this was sometimes against departmental practice, a semi-illicit addition to their workload and could thus be seen almost as a form of bootlegging 72. This study places emphasis on the need for school children to learn to read widely rather than just because they have to, but also shows that the current approach to reading and literacy is prohibitive rather than encouraging73. It would seem that current pedagogical and classroom cultures are limiting the opportunities for children to develop as individuals, in their own ways, and to engage in individual ways with reading74, making their own choices75. The Accelerated Reader programme appears to increase self-efficacy and motivation in primary students76, but the evidence for this is limited and is based on American schools, which have a different culture to the UK.
