Fostering 'habits of reflection, independent study and free inquiry': an analysis of the short-lived phenomenon of General/Liberal Studies in English vocational education and training

In 1957, 12 years after the end of World War II, the Ministry of Education issued Circular 323 to promote the development of an element of ‘liberal studies’ in courses offered by technical and further education (FE) colleges in England. This was perceived to be in some ways a peculiar or uncharacteristic development. However, it lasted over 20 years, during which time most students on courses in FE colleges participated in what were termed General or Liberal Studies classes that complemented and/or contrasted with the technical content of their vocational programmes. By the end of the 1970s, these classes had changed in character, moving away from the concept of a ‘liberal education’ towards a prescribed diet of ‘communication studies’. The steady decline in apprenticeship numbers from the late 1960s onwards accelerated in the late 1970s, resulting in a new type of student (the state-funded ‘trainee’) into colleges whose curriculum would be prescribed by the Manpower Services Commission. This paper examines the Ministry’s thinking and charts the rise and fall of a curriculum phenomenon that became immortalised in the ‘Wilt’ novels of Tom Sharpe. The paper argues that the Ministry of Education’s concerns half a century ago are still relevant now, particularly as fresh calls are being made to raise the leaving age from compulsory education to 18, and in light of attempts in England to develop new vocational diplomas for full-time students in schools and colleges.

Utility, Caller, and Patient Profile of a Novel Chemotherapy Telephone Helpline Service Within a Regional Cancer Centre in Northern Ireland

Background: The telephone is an accepted and useful means of communication for the management of patient care. The Chemotherapy Telephone Helpline (CTH) service, located in a large inner-city Trust within the United Kingdom, is a unique nurse-led service within Northern Ireland.

Objective: The objective of the study was to investigate the utility, caller, and patient profile of a novel CTH.

Methods: This was a retrospective study of telephone contacts during 2007 to the CTH. Calls were categorized by caller and patient characteristics, reason for call, and subsequent action.

Results: A total of 7498 calls were made to the CTH during 2007. Of these, 25.6% occurred outside 8AM-4PM. Callers included patients (45.8%), lay carers (31%), and health care professionals (20.5%); 35.2% of calls concerned patients with polysymptomatic problems; 36.8% of calls led directly to patients being medically assessed.

Conclusions: The utility of the CTH service confirms the need of this nurse-led service. This service facilitates access to specialist advice and support for patients, their families, and allied health care professionals.

Implications for Practice: The international significance of these findings for practice includes its demonstration of the multifaceted symptom experience of patients receiving chemotherapy and highlights the importance of rapid access to specialist cancer services for patients and their lay and professional carers. In addition, it demonstrates the capacity of helplines to identify gaps in professional skills and training.

Telephone survey evaluation of the educational impact of a distance learning course

The educational impact of a distance learning (DL) course entitled ''Health Screening for Health Promotion, was investigated using a telephone questionnaire survey. An introduction to the DL course was distributed to all community pharmacists in England (16,400); the main body of the course, on which pharmacists were examined, was distributed free of charge to all pharmacists who requested it (1,485). Pharmacists participating in the survey (868) were organized by random selection into groups and stratified according to age, sex and postcode. A matched control group was randomly drawn from those pharmacists who had not participated in the course. The DL course improved pharmacists' knowledge about health screening/health promotion issues (e.g., mean score of 66 percent achieved by a group who had completed the course; 51 percent achieved by the control group; P<0.001). Factors influencing score achieved included sex and year of registration. Males performed better than females (P<0.008) while performance decreased with number of years on the register (P<0.001).

Rôle des récepteurs Toll-like et de la protéine adaptatrice MyD88 dans la régulation de l’hepcidine et le développement des hyposidérémies associées à l’inflammation

Le fer est un oligo-élément nécessaire pour le fonctionnement normal de toutes les cellules de l'organisme et joue un rôle essentiel dans de nombreuses fonctions biologiques. Cependant, le niveau de fer dans le corps doit être bien réglé, sinon la carence en fer entraine des divers états pathologiques tels que l'anémie et la diminution de l’immunité. D'autre part, une surcharge en fer potentialise la multiplication des germes, aggrave l’infection et la formation de radicaux libres ayant des effets toxiques sur les cellules et leurs composants, ce qui favorise les maladies cardio-vasculaires, l'inflammation et le cancer. L'hepcidine (HAMP), un régulateur négatif de l'absorption du fer, induit la dégradation de la ferroportine (FPN), le seul exportateur connu de fer ce qui réduit sa libération par les macrophages et inhibe son absorption gastro-intestinale. HAMP est synthétisé principalement par les hépatocytes, mais aussi par les macrophages. Cependant, il y a très peu de données sur la façon dont HAMP est régulé au niveau des macrophages. Plus récemment, nous avons constaté que l’induction de l’hepcidin dans le foie par le polysaccharide (LPS) est dépendante de la voie de signalisation médiée par « Toll-like receptor 4 » (TLR4). Grâce au TLR4, le LPS induit l'activation des macrophages qui sécrètent de nombreuses différentes cytokines inflammatoires, y compris Interleukine 6 (IL-6), responsable de l'expression de HAMP hépatique. Dans le premier chapitre de la présente étude, nous avons étudié la régulation de HAMP dans la lignée cellulaire macrophagique RAW264.7 et dans les macrophages péritonéaux murins stimulés par différents ligands des TLRs. Nous avons constaté que TLR2 et TLR4 par l'intermédiaire de la protéine adaptatrice « myeloid differentiation primary response gene 88 » (MyD88) activent l'expression de HAMP dans les cellules RAW264.7 et les macrophages péritonéaux sauvages murins, tandis que cette expression a été supprimée dans les macrophages isolés des souris TLR2-/-, TLR4-déficiente ou MyD88-/-. En outre, nous avons constaté que la production d'IL-6 par les cellules RAW264.7 stimulées avec du LPS a été renforcée par l’ajout des quantités élevées de fer dans le milieu de culture. Au cours de l’inflammation, le niveau de HAMP est fortement augmenté. Ainsi, lorsque l'inflammation persiste, l’expression de HAMP continue à être activée par des cytokines pro-inflammatoires conduisant à une hyposidérémie. Malgré que cette dernière soit considérée comme une défense de l'hôte pour priver les micro-organismes de fer, celle ci cause un développement d'anémies nommées anémies des maladies chroniques. Ainsi, dans le deuxième chapitre de la présente étude, nous avons étudié l'implication des TLRs et leurs protéines adaptatrices MyD88 et TIR-domain-containing adapter-inducing interferon-β (TRIF) dans le développement des hyposidérémies. En utilisant des souris déficientes en MyD88 et TRIF, nous avons montré que les voies de signalisations MyD88 et TRIF sont essentielles pour l’induction de HAMP par le LPS. Malgré l'absence de HAMP, les souris déficientes ont été capables de développer une hyposidérémie, mais la réponse des souris déficientes en MyD88 a été très légère, ce qui indique l'exigence de cette protéine pour assurer une réponse maximale au LPS. En outre, nous avons constaté que la signalisation MyD88 est nécessaire pour le stockage du fer au niveau de la rate, ainsi que l'induction de lipocaline 2 (LCN2), qui est une protéine impliquée dans la fixation du fer pour limiter la croissance bactérienne. Indépendamment de MyD88 ou TRIF, l'activation de TLR4 et TLR3 a conduit, au niveau de la rate, à une diminution rapide de l’expression de FPN et du « Human hemochromatosis protein » (HFE) qui est une protéine qui limite la séquestration du fer cellulaire à partir de la circulation. Cependant, malgré cette baisse d’expression, le manque de la signalisation MyD88 a altéré de manière significative la réponse hyposidérémique. En établissant le rôle des TLRs et de la protéine adaptatrice MyD88 dans la diminution du taux du fer sérique au cours de la réponse inflammatoire, nous avons remarqué qu’en réponse au surcharge en fer les souris déficientes en MyD88 accumulent de manière significative plus de fer hépatique par rapport aux souris sauvages, et cela indépendamment des TLRs. Ainsi, dans le troisième chapitre de la présente étude, nous avons étudié le phénotype observé chez les souris déficientes en MyD88. Nous avons trouvé que l'expression de HAMP chez ces souris a été plus faible que celle des souris de type sauvage. Pour cela, nous avons exploré la signalisation à travers la voie du « Bone Morphogenetic Proteins 6 » (BMP6) qui est considérée comme étant la voie fondamentale de la régulation de HAMP en réponse aux concentrations du fer intracellulaires et extracellulaires et nous avons trouvé que l'expression protéique de Smad4, un régulateur positif de l'expression de HAMP, est significativement plus faible chez les souris MyD88-/- par rapport aux souris sauvages. En outre, on a montré que MyD88 interagit avec « mothers against decapentaplegic, Drosophila, homolog 4 » (Smad4) et que cette interaction est essentielle pour l’induction de HAMP à travers la voie BMP6. En conclusion, notre étude montre que l'expression de HAMP dans les macrophages est régulée principalement par TLR2 et TLR4 à travers la voie MyD88 et que l'accumulation du fer dans les macrophages peut affecter les niveaux des cytokines pro-inflammatoires. En outre, nos analyses démontrent que le développement d’hyposidérémie en réponse au LPS se produit par l'intermédiaire d’un mécanisme dépendant de MyD88 qui est dissociée de la production de cytokines et de HAMP. En plus, nos recherches montrent que MyD88 est nécessaire pour l'expression de Smad4 et cela pour garantir une réponse optimale à travers la signalisation BMP6, conduisant ainsi à une expression adéquate de HAMP. Enfin, la protéine MyD88 joue un rôle crucial dans, la régulation de HAMP au niveau des macrophages, la diminution du taux du fer sérique en réponse au LPS et le maintien de l'homéostasie du fer.

Fire-free land use in pre-1492 Amazonian savannas

The nature and scale of pre-Columbian land use and the consequences of the 1492 “Columbian Encounter” (CE) on Amazonia are among the more debated topics in New World archaeology and paleoecology. However, pre-Columbian human impact in Amazonian savannas remains poorly understood. Most paleoecological studies have been conducted in neotropical forest contexts. Of studies done in Amazonian savannas, none has the temporal resolution needed to detect changes induced by either climate or humans before and after A.D. 1492, and only a few closely integrate paleoecological and archaeological data. We report a high-resolution 2,150-y paleoecological record from a French Guianan coastal savanna that forces reconsideration of how pre-Columbian savanna peoples practiced raised-field agriculture and how the CE impacted these societies and environments. Our combined pollen, phytolith, and charcoal analyses reveal unexpectedly low levels of biomass burning associated with pre-A.D. 1492 savanna raised-field agriculture and a sharp increase in fires following the arrival of Europeans. We show that pre-Columbian raised-field farmers limited burning to improve agricultural production, contrasting with extensive use of fire in pre-Columbian tropical forest and Central American savanna environments, as well as in present-day savannas. The charcoal record indicates that extensive fires in the seasonally flooded savannas of French Guiana are a post-Columbian phenomenon, postdating the collapse of indigenous populations. The discovery that pre-Columbian farmers practiced fire-free savanna management calls into question the widely held assumption that pre-Columbian Amazonian farmers pervasively used fire to manage and alter ecosystems and offers fresh perspectives on an emerging alternative approach to savanna land use and conservation that can help reduce carbon emissions.

How acceptable is a referral and telephone-based outcall programme for men diagnosed with cancer? A feasibility study

The objective of this study was to determine the feasibility and acceptability of a referral and outcall programme from a telephone-based information and support service, for men newly diagnosed with colorectal or prostate cancer. A block randomized controlled trial was performed involving 100 newly diagnosed colorectal and prostate cancer patients. Patients were referred to the Cancer Information Support Service (CISS) through clinicians at diagnosis. Clinicians were randomized into one of three conditions. Active referral 1: specialist referral with four CISS outcalls: (1) ≤1 week of diagnosis; (2) at 6 weeks; (3) 3 months; and (4) 6 months post diagnosis. Active referral 2: specialist referral with one CISS outcall ≤1 week of diagnosis. Passive referral: specialist recommended patient contacts CISS, but contact at the patient's initiative. Patients completed research questionnaires at study entry (before CISS contact), then 4 and 7 months post diagnosis. Overall, 96% of participants reported a positive experience with the referral process; 87% reported they were not concerned about receiving the calls; and 84% indicated the timing of the calls was helpful. In conclusion, the referral and outcall programme was achievable and acceptable for men newly diagnosed with colorectal or prostate cancer.

A cluster randomised trial of a telephone-based intervention for parents to increase fruit and vegetable consumption in their 3-to 5-year-old children : study protocol

Background: Inadequate fruit and vegetable consumption in childhood increases the risk of developing chronic disease. Despite this, a substantial proportion of children in developed nations, including Australia, do not consume sufficient quantities of fruits and vegetables. Parents are influential in the development of dietary habits of young children but often lack the necessary knowledge and skills to promote healthy eating in their children. The aim of this study is to assess the efficacy of a telephone-based intervention for parents to increase the fruit and vegetable consumption of their 3- to 5-year-old children.
Methods/Design: The study, conducted in the Hunter region of New South Wales, Australia, employs a cluster randomised controlled trial design. Two hundred parents from 15 randomly selected preschools will be randomised to receive the intervention, which consists of print resources and four weekly 30-minute telephone support calls delivered by trained telephone interviewers. The calls will assist parents to increase the availability and accessibility of fruit and vegetables in the home, create supportive family eating routines and role-model fruit and vegetable consumption. A further two hundred parents will be randomly allocated to the control group and will receive printed nutrition information only. The primary outcome of the trial will be the change in the child's consumption of fruit and vegetables as measured by the fruit and vegetable subscale of the Children's Dietary Questionnaire. Pre-intervention and post-intervention parent surveys will be administered over the telephone. Baseline surveys will occur one to two
weeks prior to intervention delivery, with follow-up data collection calls occurring two, six, 12 and 18 months following baseline data collection.
Discussion: If effective, this telephone-based intervention may represent a promising public health strategy to increase fruit and vegetable consumption in childhood and reduce the risk of subsequent chronic disease.

Faster and parameter-free discord search in quasi-periodic time series

Time series discord has proven to be a useful concept for time-series anomaly identification. To search for discords, various algorithms have been developed. Most of these algorithms rely on pre-building an index (such as a trie) for subsequences. Users of these algorithms are typically required to choose optimal values for word-length and/or alphabet-size parameters of the index, which are not intuitive. In this paper, we propose an algorithm to directly search for the top-K discords, without the requirement of building an index or tuning external parameters. The algorithm exploits quasi-periodicity present in many time series. For quasi-periodic time series, the algorithm gains significant speedup by reducing the number of calls to the distance function.

How calls from carers, friends and family members of someone affected by cancer differ from those made by people diagnosed with cancer; analysis of 4 years of South Australian Cancer Council Helpline data

PURPOSE: The purpose of this study is to determine how people diagnosed with cancer who call the Cancer Council Helpline in South Australia differ from carers/family/friends (caregivers) who call. METHOD: Descriptive, retrospective audit of calls from people who contacted Cancer Council Helpline in South Australia between 16 April 2009 and 16 April 2013 who were diagnosed with cancer (n = 5766) or were the caregivers (n = 5174) of a person with cancer. RESULTS: Caregivers were more likely to be female (p < 0.001); younger in age (p < 0.001); call regarding cancer that was metastasised/widespread/advanced, terminal or at an unknown stage (p < 0.001) and phone requesting general cancer information or emotional support (p < 0.001). This group was more distressed (p < 0.001) but less likely (p = 0.02) to be offered and/or accept referrals to counselling than people diagnosed with cancer who called. Follow-up care was required by 63.5 % of caregivers and 73.1 % of people with cancer according to distress management guidelines; 8.5 and 15.3 %, respectively, accepted referrals to internal services. The most frequently discussed topic for both groups was emotional/psychological concerns. There were no differences in remoteness of residence or call length between groups. CONCLUSIONS: Caregivers represented different demographic groups than people diagnosed with cancer who called this helpline. The two groups phoned for different issues, at different stages of disease progression, displayed different levels of distress and, therefore, may benefit from services being tailored to meet their unique needs. These results also demonstrate the capacity of helplines to complement other health services and confirm that callers to cancer helplines exhibit high levels of distress.

Inter-hospital 'patient expect' calls of clinical handovers for expected patients transferred from rural to metropolitan hospitals: a retrospective clinical audit

Patients requiring inter-hospital air transport across large geographical spaces are at significant risk of adverse outcomes. The aims of this study were to examine the characteristics of clinical handover conducted by telephone and subsequently transcribed in medical records during the inter-hospital transfer of rural patients, and to identify any deficits of this telephone clinical handover. A retrospective audit was conducted of transcribed telephone handovers ('patient expect' calls) occurring with inter-hospital transfers from two rural hospitals to a metropolitan tertiary hospital of all rural patients (n = 127) between January and June 2012. Patient transport between various sites occurred through the Royal Flying Doctor Service. For these hospitals, patient expect calls constituted the only handover record for clinicians during the time of patient transport. Information on patient identification stickers relating to patients' age or gender did not always correspond with details collected during patient expect calls. The name of a clinician at the receiving hospital authorising the transfer was provided in 14 calls (11.1%). It was difficult to determine who made and received calls, and who accepted responsibility for patients at the receiving site. Deterioration in a patient's condition was made in three calls. Actions to be taken after patients' arrival were included in 24 (19%) calls. Planning was restricted to identifying who to contact to review instructions. Inconsistent and overuse of abbreviations was likely to have affected the ability to accurately read back patient information. Crucial information was missing from calls, which may have contributed to delayed and inappropriate delivery of care.

QUANTIFYING UNCERTAINTY IN GENOTYPE CALLS

Genome-wide association studies (GWAS) are used to discover genes underlying complex, heritable disorders for which less powerful study designs have failed in the past. The number of GWAS has skyrocketed recently with findings reported in top journals and the mainstream media. Mircorarrays are the genotype calling technology of choice in GWAS as they permit exploration of more than a million single nucleotide polymorphisms (SNPs)simultaneously. The starting point for the statistical analyses used by GWAS, to determine association between loci and disease, are genotype calls (AA, AB, or BB). However, the raw data, microarray probe intensities, are heavily processed before arriving at these calls. Various sophisticated statistical procedures have been proposed for transforming raw data into genotype calls. We find that variability in microarray output quality across different SNPs, different arrays, and different sample batches has substantial inuence on the accuracy of genotype calls made by existing algorithms. Failure to account for these sources of variability, GWAS run the risk of adversely affecting the quality of reported findings. In this paper we present solutions based on a multi-level mixed model. Software implementation of the method described in this paper is available as free and open source code in the crlmm R/BioConductor.

Cut Out By The Middle Man: The Free Speech Implications Of Social Network Blocking and Banning In The EU

This article examines social network users’ legal defences against content removal under the EU and ECHR frameworks, and their implications for the effective exercise of free speech online. A review of the Terms of Use and content moderation policies of two major social network services, Facebook and Twitter, shows that end users are unlikely to have a contractual defence against content removal. Under the EU and ECHR frameworks, they may demand the observance of free speech principles in state-issued blocking orders and their implementation by intermediaries, but cannot invoke this ‘fair balance’ test against the voluntary removal decisions by the social network service. Drawing on practical examples, this article explores the threat to free speech created by this lack of accountability: Firstly, a shift from legislative regulation and formal injunctions to public-private collaborations allows state authorities to influence these ostensibly voluntary policies, thereby circumventing constitutional safeguards. Secondly, even absent state interference, the commercial incentives of social media cannot be guaranteed to coincide with democratic ideals. In light of the blurring of public and private functions in the regulation of social media expression, this article calls for the increased accountability of the social media services towards end users regarding the observance of free speech principles

AN ECONOMIC ANALYSIS OF THE DEMAND FOR CARE IN A FREE-STANDING EMERGENCY CENTER

Free-standing emergency centers (FECs) represent a new approach to the delivery of health care which are competing for patients with more conventional forms of ambulatory care in many parts of the U.S. Currently, little is known about these centers and their patient populations. The purpose of this study, therefore, was to describe the patients who visited two commonly-owned FECs, and determine the reasons for their visits. An economic model of the demand for FEC care was developed to test its ability to predict the economic and sociodemographic factors of use. Demand analysis of other forms of ambulatory services, such as a regular source of care (RSOC), was also conducted to examine the issues of substitution and complementarity.^ A systematic random sample was chosen from all private patients who used the clinics between July 1 and December 31, 1981. Data were obtained by means of a telephone interview and from clinic records. Five hundred fifty-one patients participated in the study.^ The typical FEC patient was a 26 year old white male with a minimum of a high school education, and a family income exceeding $25,000 a year. He had lived in the area for at least twenty years, and was a professional or a clerical worker. The patients made an average of 1.26 visits to the FECs in 1981. The majority of the visits involved a medical complaint; injuries and preventive care were the next most common reasons for visits.^ The analytic results revealed that time played a relatively important role in the demand for FEC care. As waiting time at the patients' regular source of care increased, the demand for FEC care increased, indicating that the clinic serves as a substitute for the patients' usual means of care. Age and education were inversely related to the demand for FEC care, while those with a RSOC frequented the clinics less than those lacking such a source.^ The patients used the familiar forms of ambulatory care, such as a private physician or an emergency room in a more typical fashion. These visits were directly related to the age and education of the patients, existence of a regular source of care, and disability days, which is a measure of health status. ^

Evaluation of the influence of toll systems on energy consumption and CO2 emissions: A case study of a Spanish highway

This paper studies the energy consumption and subsequent CO2 emissions of road highway transportation under three toll systems in Spain for four categories of vehicles: cars, vans, buses and articulated trucks. The influence of toll systems is tested for a section of AP-41 highway between Toledo and Madrid. One system is free flow, other is traditional stop and go and the last toll system operates with an electronic toll collection (ETC) technology. Energy consumption and CO2 emissions were found to be closely related to vehicle mass, wind exposure, engine efficiency and acceleration rate. These parameters affect, directly or indirectly, the external forces which determine the energy consumption. Reducing the magnitude of these forces through an appropriate toll management is an important way of improving the energy performance of vehicles. The type of toll system used can have a major influence on the energy efficiency of highway transportation and therefore it is necessary to consider free flow.
