High precision control technique for constant current regulation in primary‐side regulation systems
Authors: Wang Zeyu , Lai Xinquan , He Huisen
Published: November 2014

A constant current control technique for a primary‐side control system is proposed to realise high precision output current regulation. With the novel ring detect and demagnetisation portion control technique, the ending time of demagnetisation can be accurately determined and the portion of demagnetisation in a switching period remains precisely the same. The simulation results show that with this control technique, the variation of output current is less than ±1.5% of the target value.
Design, analysis and implementation of a buck–boost DC/DC converter
Authors: Ajami Ali , Ardi Hossein , Farakhor Amir
Published: November 2014

A novel buck–boost converter is presented in this study. This converter is based on Cuk converter. Therefore it inherits all the advantages of Cuk converter such as low output voltage ripple and minimal radio frequency interference. In addition, some implementation problems of KY converters are solved. The proposed converter has higher voltage gain in step‐up mode in comparison with Cuk converter. Moreover, this converter expands the continuous conduction mode (CCM) operational region. In the suggested topology, the gate of the switch is referenced to ground, so this converter does not need a floating gate drive. Simulation results of the suggested converter are presented in different operational conditions. To verify the operation of the proposed converter, experimental results are provided using a hardware prototype that operates in both CCM and discontinuous conduction mode.
Hybrid power electronic controller for combined operation of constant power and maximum power point tracking for single‐phase grid‐tied photovoltaic systems
Authors: Dharmaian Retnam Binu Ben Jose , Nanjappa Gounder Ammasai Gounden , Ammasai Gounden Vasanth
Published: November 2014

This study presents a hybrid technique that offers constant power operation for single‐phase grid‐tied photovoltaic (PV) systems while performing maximum power point tracking function. A boost converter and a line commutated inverter (LCI) have been used for interfacing PV array with utility grid. Fixed firing angle of the LCI keeps the dc‐link voltage constant and the boost converter extracts maximum power from the solar PV array by simply adjusting the duty ratio of the boost converter. A low‐capacity battery bank connected at the dc link is used to deliver constant power to grid. Harmonic filter is eliminated as the system inherently delivers quality supply with reduced current harmonics. PIC microcontrollers have been programmed for generating pulses to the inverter and the boost converter. The system has been simulated in MATLAB/Simulink and the simulation results are presented. The parameters of a PV panel rated for 100 W, 21.5 V and 6.83 A have been used for the simulation. Experiments have been conducted on the 21.5 V, 6.83 A PV panel for obtaining a constant power of 80 W with varying irradiation and the results correlate with the simulation study.
Sensorless control of single voltage source converter‐based doubly fed induction generator for variable speed wind energy conversion system
Authors: Swami Naidu N. Krishna , Singh Bhim
Published: November 2014

This study deals with the analysis, design and control of single voltage source converter (VSC)‐based grid connected doubly fed induction generator (DFIG) for wind energy conversion system (WECS) with maximum power point tracking capability. This proposed system uses stator flux‐based model reference adaptive system algorithm for the sensorless rotor position estimation. In this proposed topology, grid side converter is replaced by a battery energy storage system (BESS) in the dc link. The designs of all the components such as BESS, VSC and wind turbine are explained in detail. This proposed topology is implemented using a digital signal processor. This developed WECS is tested extensively in sub‐synchronous, synchronous and super‐synchronous speeds regions and test results are presented in all these cases. The performance of this proposed topology is demonstrated for the dynamics in wind speed by the experimental verification. A comparative study of proposed single VSC‐based WECS system is made with the conventional double VSC‐based DFIG.

Authors: Kuznetsov A. S. , Sadofev S. , Schäfer P. , Kalusniak S. , Henneberger F.
Published: November 2014

Single crystalline thin films of Er2O3, demonstrating efficient 1.5 μm luminescence of Er3+ at room temperature were grown on Al2O3 substrate by molecular beam epitaxy. The absorption coefficient at 1.536 μm was found to reach 270 cm−1 translating in a maximal possible gain of 1390 dBcm−1. In conjunction with the 10% higher refractive index as compared to Al2O3, this opens the possibility to use Er2O3:sapphire films as short-length waveguide amplifiers in telecommunication.

Elasmobranchs represent important components of marine ecosystems, but they can be vulnerable to overexploitation. This has driven investigations into the population genetic structure of large-bodied pelagic sharks, but relatively little is known of population structure in smaller demersal taxa, which are perhaps more representative of the biodiversity of the group. This study explores spatial population genetic structure of the small-spotted catshark (Scyliorhinus canicula), across European seas. The results show significant genetic differences among most of the Mediterranean sample collections, but no significant structure among Atlantic shelf areas. The data suggest the Mediterranean populations are likely to have persisted in a stable and structured environment during Pleistocene sea-level changes. Conversely, the Northeast Atlantic populations would have experienced major changes in habitat availability during glacial cycles, driving patterns of population reduction and expansion. The data also provide evidence of male-biased dispersal and female philopatry over large spatial scales, implying complex sex-determined differences in the behaviour of elasmobranchs. On the basis of this evidence, we suggest that patterns of connectivity are determined by trends of past habitat stability that provides opportunity for local adaptation in species exhibiting philopatric behaviour, implying that resilience of populations to fisheries and other stressors may differ across the range of species.

Published: November 2014

Identification of the genomic regions that regulate transcription remains an important open problem. We have recently shown that global run-on and sequencing (GRO-seq) with enrichment for 5'-capped RNAs reveals patterns of divergent transcription that accurately mark active transcriptional regulatory elements (TREs), including enhancers and promoters. Here, we demonstrate that active TREs can be identified with comparable accuracy by applying sensitive machine-learning methods to standard GRO-seq and PRO-seq data, allowing TREs to be assayed together with transcription levels, elongation rates, and other transcriptional features, in a single experiment. Our method, calleddiscriminativeRegulatoryElement detection fromGRO-seq (dREG), summarizes GRO-seq read counts at multiple scales and uses support vector regression to predict active TREs. The predicted TREs are strongly enriched for marks associated with functional elements, including H3K27ac, transcription factor binding sites, eQTLs, and GWAS-associated SNPs. Using dREG, we survey TREs in eight cell types and provide new insights into global patterns of TRE assembly and function.

Authors: Immonen Marika , Wu Jinhua , Juan Yan Hui , Chen Peifeng , Xiong Xu Jian , Rapala‐Virtanen Tarja
Published: November 2014

Purpose

The purpose of this paper is to study fabrication of optical‐PCBs on panel scale boards in a conventional modern PCB process environment. It evaluates impacts on board design and manufacturing with the developed optical board verifiers outlining challenges and requirements for manufacturing low‐loss waveguide structures and optical building blocks. The study aims to expand the current knowledge in the field by adding results obtained by utilizing industrial production infrastructure and developed scalable manufacturing processes to fabricate optical‐PCBs and board assemblies in high‐volumes and low‐cost manner.

Design/methodology/approach

Impacts on board design and manufacturing were studied with the developed optical technology verifiers. One verifier is optical‐PCB with embedded waveguides, integrated i/o couplers and optical vias. Another verifier is large size PCB with optical layer. A system‐level optical board assembly with 12.5 Gb/s Tx/Rx devices on surface mounted ball grid array (BGA) modules is designed for optical link analysis. Fabricated optical structures on verifiers are evaluated of their physical characteristics utilizing optical, SEM, LSCM analysis methods. Performance testing is conducted using standard optical transmission measurement methods and equipment.

Findings

The paper provides empirical results about fabrication of multimode optical waveguides with conventional PCB process equipment. Results suggest that current coating and imaging equipments are capable of producing optical waveguide patterns with high resolution and size accuracy. However, fabricators would require larger process window and defect tolerance for processing optical materials to obtain low‐loss waveguides with sufficient yields.

Research limitations/implications

Because of the limited amount of design variants in production verifiers evaluated in this paper, some impacts like effect of base material, board construction, optical layer location and beam coupling solution were not evaluated. Likewise, impacts on long‐term stability and cost were not addressed. These factors however require further investigation to address technical feasibility of optical PCBs technology prior commercial high volume production.

Practical implications

The paper includes implications for the development of a fabrication methods and testing procedures for optical polymer waveguide layers on PCBs.

Originality/value

This paper fulfils need to provide results on design, fabrication and characterization of optical PCBs and backplanes from industrial fabricator's perspective. The paper provides input for end‐user and developers to evaluate technical performance, robustness, and maturity of building blocks and supply chain to support polymer waveguide based technology for intra‐system optical links.
Initial studies to optimise the sonochemical surface modification of a high Tg laminate
Authors: Mkhlef Bilal , Cobley Andy , Paniwnyk Larysa , Mason Tim
Published: November 2014

Purpose

The purpose of this paper is to develop an optimised sonochemical surface modification process which could be operated at low temperature and which uses non‐hazardous chemistry with short treatment times. A range of sonochemical parameters such as ultrasonic intensity/power and process temperature were investigated.

Design/methodology/approach

A 20 kHz ultrasonic probe was used as the ultrasonic source. Ultrasound was applied through deionised water (DI) to sonochemically surface modify a high Tg epoxy laminate material (Isola 370 HR). The efficiency of the sonochemical surface modification process was determined by weight loss, roughness, adhesion and scanning electron microscopy (SEM).

Findings

This study has confirmed that ultrasound has the ability to surface modify a high Tg epoxy substrate material (Isola 370 HR). Weight loss and roughness values were increased by using an optimised ultrasonic process compared to control samples which were processed under “silent” conditions. Adhesion testing showed an improvement in the adhesion level between the surface and the subsequently electroless plated copper.

Originality/value

Surface modification of high Tg materials generally utilizes wet chemical methods. These processes involve using hazardous chemicals, high temperatures, require high volumes of water for rinsing and need relatively long immersion times. This research has shown that by optimising ultrasonic parameters, surface modification can be brought about in deionised water (DI) at low temperature.
Algorithm‐based, drive design for a ventricular assist device
Authors: Pohlmann André , Leßmann Marc , Hameyer Kay
Published: November 2014

Purpose

The purpose of this paper is to describe a design process for a drive of a ventricular assist device (VAD) under the consideration of constraints given by the application. In this case, these constraints are the possibility to implant the VAD system, providing a sufficient perfusion of the human body and cutting down development costs.

Design/methodology/approach

In the described approach an optimization algorithm is integrated in the initial stage of the design process for a drive system.

Findings

During simulations the optimum drive design under the implantation constraints of the given VAD system is found. The key constraints of this design, which are torque, axial force and losses, are validated during initial test bench measurements of a drive prototype.

Practical implications

The described design process enables an optimum drive design from the beginning of a VAD development. This reduces the time to initial and chronic in vivo test, which are required to be approved for the market later. Therefore, this approach cuts development and device costs. Additionally, this design process can be transferred for the design of other drive concepts and applications.

Originality/value

The developed and proved method in this paper enables a competitive and reliable drive design.

Authors: Arnautovski‐Toševa Vesna , El Khamlichi Drissi Khalil , Kerroum Kamal
Published: November 2014

Purpose

The purpose of this paper is to present a frequency domain analysis of high frequency behaviour of an indoor Powerline communications (PLC) circuit in the presence of a plaster board/concrete wall structure. The main purpose of this analysis is to investigate the influence of the wall structure on the current distribution and the radiated electric field due to PLC signals in range from 3 MHz to 30 MHz.

Design/methodology/approach

The mathematical model is based on the full‐wave theory formulated by the Mixed Potential Integral Equation (MPIE) for the electric field due to energized thin‐wire conductors in stratified media. The solution for the current and the electric field distribution is obtained by using the Method of Moments.

Findings

Numerical results are obtained of the current distribution along the conductors of the PLC circuit and the radiated electric field in presence of a wall structure. Two cases are analyzed: when the circuitry is placed in the wall; and when the circuitry is placed outside the wall.

Practical implications

The paper presents the mathematical model that may be applied for analysis of indoor PLC circuits placed in presence of wall structures.

Originality/value

In the paper, a full‐wave model of the PLC circuitry in presence of a wall structure is developed, on the basis of MPIE and the Method of Moments.
Estimation of simulated transfer function to discriminate axial displacement and radial deformation of transformer winding
Authors: Karimifard Peyman , Gharehpetian G.B. , Javid Ghanizadeh Ahmad , Tenbohlen Stefan
Published: November 2014

Purpose

The transfer function (TF) method is a reliable tool for the detection of the transformer winding deformation and displacement. One of the most important problems is the discrimination between these mechanical defects using a measured TF. The purpose of this paper is to suggest a new method based on the TF estimation, to detect the type of the mechanical defects in high voltage inhomogeneous winding of a power transformer, i.e. the winding is not homogeneous and has interleaved and inverted disks.

Design/methodology/approach

The methodology of this paper is based on the estimation of the TF and in normal and defected cases can be properly achieved using vector fitting method. To study the mechanical defects, the detailed model of the transformer is in the frequency range of kHz<f.

Findings

In this paper, comparison of Nyquist diagrams of the estimated TF curves result in a new discrimination method between mechanical defects and localization of the deformed section in the transformer winding. The interpretation of the TF changes is based on comparison of the Nyquist diagrams in a selected frequency range.

Originality/value

This paper suggests new discrimination method between mechanical defects and localization of the deformed section in the transformer winding which is based on the TF estimation.
Analysis of QoS for DVB‐RCS‐based IP network
Authors: Jasola Sanjay , Kinshuk
Published: November 2014

Purpose

The internet has been used to transport data in the form of packet. Multimedia applications including voice and video are being sent using the internet. In the past, the internet did not support any kind of sophisticated quality of service (QoS) mechanism. Although the type of service (ToS) field in the internet protocol (IP) header has been present and allowed the differentiated treatment of packets, it was never really used on a large‐scale. IP applications have been mostly used on terrestrial networks so far. This paper aims to describe the architecture of a DVB‐RCS based satellite network supporting interactive and multimedia applications.

Design/methodology/apporach

The use of TCP/IP has made it possible to have two way communication using open standard satellite networks based on digital video broadcast return channel via satellite (DVB‐RCS). The voice and video are sensitive to delay and jitter so bandwidth must be guaranteed while transporting it. With the extensive use of IP for carrying voice and video, there is a need to add QoS functionality in satellite networks. The performance of data transfer using voice and video with reference to QoS parameters in satellite network is analyzed in this paper.

Findings

The results show that satellite networks based on DVB‐RCS can carry voice and video traffic and offer good quality of service in terms of packet loss and jitter but are poor in quality in terms of packet delay.

Originality/value

This paper describes the architecture of a DVB‐RCS based satellite network supporting interactive and multimedia applications.
Risks and benefits of selective (re)presentation of interviewees' talk: some insights from discourse analysis
Authors: MacLeod Nicci J.
Published: November 2014

Purpose

The purpose of this paper is to examine the quality of evidence collected during interview. Current UK national guidance on the interviewing of victims and witnesses recommends a phased approach, allowing the interviewee to deliver their free report before any questioning takes place, and stipulating that during this free report the interviewee should not be interrupted. Interviewers, therefore, often find it necessary during questioning to reactivate parts of the interviewee's free report for further elaboration.

Design/methodology/approach

The first section of this paper draws on a collection of police interviews with women reporting rape, and discusses one method by which this is achieved – the indirect quotation of the interviewee by the interviewer – exploring the potential implications for the quality of evidence collected during this type of interview. The second section of the paper draws on the same data set and concerns itself with a particular method by which information provided by an interviewee has its meaning “fixed” by the interviewer.

Findings

It is found that “formulating” is a recurrent practice arising from the need to clarify elements of the account for the benefit of what is termed the “overhearing audience” – in this context, the police scribe, CPS, and potentially the Court. Since the means by which this “fixing” is achieved necessarily involves the foregrounding of elements of the account deemed to be particularly salient at the expense of other elements which may be entirely deleted, formulations are rarely entirely neutral. Their production, therefore, has the potential to exert undue interviewer influence over the negotiated “final version” of interviewees' accounts.

Originality/value

The paper highlights the fact that accurate re‐presentations of interviewees' accounts are a crucial tool in ensuring smooth progression of interviews and that re‐stated speech and formulation often have implications for the quality of evidence collected during significant witness interviews.
PLEM: a Web 2.0 driven Long Tail aggregator and filter for e‐learning
Authors: Amine Chatti Mohamed , Anggraeni  , Jarke Matthias , Specht Marcus , Maillet Katherine
Published: November 2014

Purpose

The personal learning environment driven approach to learning suggests a shift in emphasis from a teacher‐driven knowledge‐push to a learner‐driven knowledge‐pull learning model. One concern with knowledge‐pull approaches is knowledge overload. The concepts of collective intelligence and the Long Tail provide a potential solution to help learners cope with the problem of knowledge overload. The paper aims to address these issues.

Design/methodology/approach

Based on these concepts, the paper proposes a filtering mechanism that taps the collective intelligence to help learners find quality in the Long Tail, thus overcoming the problem of knowledge overload.

Findings

The paper presents theoretical, design, and implementation details of PLEM, a Web 2.0 driven service for personal learning management, which acts as a Long Tail aggregator and filter for learning.

Originality/value

The primary aim of PLEM is to harness the collective intelligence and leverage social filtering methods to rank and recommend learning entities.

The All Wales Learning Disability Strategy: current status and implications for people with mental health needs or severe challenging behaviour
Authors: Felce David , Allen David
Published: November 2014

This paper briefly summarises the main Welsh policy principles that apply to all people with learning disabilities, including those with mental health needs or severe challenging behaviour. We briefly review progress in supporting people with complex behavioural needs, reflect on areas where development in practice has not lived up to policy rhetoric and also examine the consequences of this policy to practice gap. We then describe current barriers to further service development. Finally, we suggest a number of changes that are necessary for the current inadequacies to be resolved.
The Association for Real Change (ARC) commences work on Mental Health in Learning Disability Knowledge Centre
Authors: Grundy David
Published: November 2014

People with learning disabilities are more likely to have mental health problems than the rest of the population (Foundation for People with Learning Disabilities, 2002). However these issues are often not recognised until the situation becomes more difficult or serious. Frontline social care staff are often unaware of the basic things they can do to promote positive mental health and families are unaware of the services that are available to help them. People with learning disabilities and mental health problems also often fall in the gaps between different services. This Knowledge Centre will aim to be somewhere they feel they ‘belong’ and that is for them.
FraX‐E: underdiagnosed, undertreated, under‐researched and misunderstood?

The authors provide some background on the condition and report on recent research and evidence. Three case reports are outlined and the specific behavioural aspects of the syndrome are considered. The authors argue that it is important that the behavioural phenotype for FraX‐E is clearly identified and defined in order to give those with the condition relevant psychological and educational support in the future.
Investigating staff knowledge and attitudes towards working with adults with learning disabilities and mental health difficulties
Authors: Rose Nikki , O'Brien Alex , Rose John
Published: November 2014

This research aimed to investigate staff knowledge and attitudes towards working with adults with both a learning disability and a mental health difficulty. Government policy in the UK suggests a shift in service provision such that the treatment of people with a learning disability who have mental health problems should be undertaken by mainstream mental health services rather than specialist learning disability services.Staff members from both specialist and mainstream services took part in a series of focus groups to discuss their experiences and attitudes about working with this group of people. The transcriptions of the groups were analysed to identify common themes. Findings from the study suggest that staff within mainstream services currently feel that they are inadequately trained to deal with the often complex mental health needs of this group. Conversely, staff in learning disability services expressed concern about losing their specialist skills in generic services.The implications of the themes raised are discussed, particularly in relation to future service provision. Care will need to be taken if service redesign is to be achieved without detriment to service users.
The assessment and treatment of a man with mild learning disability, violent behaviour and chronic low self‐esteem: a case study
Authors: Bishop Amanda , Henry Jayne
Published: November 2014

The following case study describes the assessment, formulation and treatment of a man with mild learning disabilities and a history of violent behaviour. Following several years of offence‐related work, identification of chronic low self‐esteem provided an alternative approach to addressing the risk of violence by treatment based on the cognitive model of low self‐esteem. Global self‐esteem and fear of negative evaluation were assessed at baseline, middle and end of treatment and at one‐month follow‐up. Although scores improved over the course of 23 sessions and were maintained at one‐month follow‐up, the change was minimal and unlikely to be clinically significant. However, the client reported benefits from therapy and there were observable positive behaviour changes. Discharge was facilitated from secure services to supported living in the community. The results from this case study show that, with adaptation, cognitive behavioural therapy for low self‐esteem may successfully be applied to people with mild learning disabilities. Therapy to address issues underlying offending behaviour is often required in addition to offending behaviour programmes in order to reduce risk of re‐offending.
Chaotic dynamics and chaos control in differentiated Bertrand model with heterogeneous players
Authors: Hu Rong , Xia Hong‐shan
Published: November 2014

Purpose

The purpose of this paper is to investigate the chaotic dynamics behaviours and chaos control of differentiated Bertrand model.

Design/methodology/approach

The paper analyzes a nonlinear differentiated Bertrand duopoly game by using the theory of bifurcations of dynamical system, where players have heterogeneous expectations and nonlinear cost function: two types of players are considered – bounded rational and naive expectation. The equilibrium point and local stability of the duopoly game are investigated.

Findings

The paper demonstrates that as some parameters of the game are varied, the stability of Nash equilibrium is lost through period doubling bifurcation. The chaotic features are justified numerically via computing Lyapunov exponents, and sensitive dependence on initial conditions. By using the delay feedback control method, the authors have made the system form chaotic state to stable state.

Originality/value

This paper fulfils an identified need to study the diversity of expectations and how to lead to rich dynamics and complexity.

Authors: Zhang Jun , Liu Zuqiang , Liu Yanjie , Liu Yong
Published: November 2014

Purpose

The purpose of this paper is to apply grey statistical model to identify and classify live fault rupture.

Design/methodology/approach

Based on grey statistical mode, this paper uses eight faults' ripping speed observation data from 1997 to 2001, according to the grey statistics method for analysis, and recognizes active fault rupture situation. Using the conventional methods, namely taking all faults monitoring stations' average dislocation rate to analysis and make judgment, the average results are obtained.

Findings

The results show that the results are closer to reality because the grey statistical evaluation method has considered dislocation rate and other discrete factors.

Practical implications

The method exposed in the paper can be used to monitor and recognize live fault rupture in earthquake prediction.

Originality/value

According to the fault dislocation rate, this paper advances active fault rupture identification and classification method based on grey statistical model.

About 4 per cent (n=4) of the referrals were from the adult learning disability services.

Originality/value

– The findings from the descriptive study suggest a significant gap in diagnostic services for adults with ADHD who present with high rates of co-morbidity.
Health Pharma: managing supply chain
Authors: Dastidar Surajit Ghosh , Thakurta Rahul , Sreeram Anusha
Published: November 2014

Subject area

The case deals with the Bullwhip phenomena that can be observed in a supply chain.

Study level/applicability

This case is suitable for all levels of students, undergraduate MBA to Executive MBA classes and practitioners. Assignment questions are designed from the perspective of teaching this case to a business student audience. The case is ideally suited for a supply chain management course and can be introduced to demonstrate the bullwhip effect in an operations management course.

Case overview

Set in May 2011, the case presents the discussions in the meeting summoned by Mr Srinivas, the director (technical) of Health Pharma (not the name of a real organization) in response to the huge losses faced by the organization in the last financial year. The discussions point to the inability of the organization to appropriately forecast demand across the different echelons and also absence of information transparency, leading to the loss. The catastrophe indicated the need to adopt an ERP solution, which was earlier overlooked by Health Pharma management.

Expected learning outcomes

These are an introduction to the concepts of the bullwhip effect and the case presents a managerial solution to the supply chain problem demonstrated.

Supplementary materials

Teaching notes are available for facilitating the instructor to present and discuss the case in a classroom setting.

Bioethical analysis of the Promethean and biophilia global biobusiness
Authors: Dean Parhizgar Kamal , Parhizgar Suzan , Parhizgar Fuzhan
Published: November 2014

In this article our objective is to do a very deep analysis into biobusinesses and bioethics in order to identify holistic views concerning business enterprises in biopharmaceutical and biotechnological industries. We are arguing that biobusinesses and biotechnologies are not error free because in reality bio‐technoscientific discoveries and breakthroughs are not viewed as holistic real “natural logic”. They are “techno‐scientific logic”. Through a biosophical deliberation, if we believe that there is a difference between “natural logic” and “scientific logic”, then we may conclude that there are erroneous thoughts which exist and if existence is based on thinking, then false thoughts are as “real” as any misunderstanding among bio‐techno‐scientists and practitioners may thus end up with global catastrophes. Through a biosophical logic, we may choose both paths of “natural logic” and “scientific logic” in order to arrive in a real consensus conclusion. In addition, in this article we have examined the Promethean biosophical and biophilia perceptions and practices of global biopharmaceutical industries and biotechological businesses concerning bioethics.

NO INDUSTRIAL FIRM large or small can afford to be without personnel skilled in the properties and uses of materials and in the tools and techniques of manufacture. Such personnel are the lifeblood of industry; yet in a large number of firms the need for broad training in these fundamental matters is scarcely recognised, and reliance is placed on processes, techniques and designs which, though they may have served adequately in the past, are unlikely to suffice in the highly industrialised, and increasingly competitive, world of the future. It is only by increasing the scale and quality of the further education and practical training of the recruits to industry that we shall be able to improve the material basis of life in this country, strengthen our economic position in world markets, and fulfil our many obligations abroad.

Interlinguistics — a Branch of Language Study
Authors: Spathaky Ronald
Published: November 2014

A place for auxiliary languages in vocational further education is a long way off, but few would dare to say it will never be won. For the present it is important to know that a language of this type does not necessarily represent one man's guess at what would be an improvement on national languages, but may be a scientific approach to finding a widely comprehensible ‘average’ language. The letter from Poland which the author quotes should present even the most unassuming linguist with few difficulties.
Parental choice—antidote to education's mandarin syndrome
Authors: Boyson Rhodes
Published: November 2014

The rising discontent with the falling standards of schools in our large cities may cause a radical rethink of their method of financing and organisation which could be very salutary indeed. At the moment more and more money is poured into city schools, particularly in London; yet truancy rates rocket, literacy and numeracy decline, and violence and indiscipline are threatened in almost every school. It is very possible that more expenditure, smaller classes, more new buildings and more support services will do nothing to rectify these problems. Indeed all these so‐called ‘improvements’ have existed in parallel with the continued decline of the standards of state city schools.
The Corrosion Story

During the latter half of the 19th century a number of detailed and interesting scientific experiments were carried out to investigate how various factors influenced the corrosion rate of metals. The three major areas of interest were the influence of scale, galvanism and magnetism.
Groups in Workplace 2000: A Multicultural Perspective
Authors: Proehl Rebecca A.
Published: November 2014

In this article, the author begins with the assumptions that 1) groups are becoming an increasingly popular way of dealing with organizational challenges and problems and 2) organizations are becoming increasingly multicultural in their membership. Dr. Proehl seeks to demonstrate that the traditional ways of working with groups are not effective when the membership is multicultural. To support this contention, she identifies six commonly accepted assumptions about how to develop high performing groups and then challenges each assumption from a crosscultural perspective. The author closes the article by offering suggestions for working effectively with multicultural groups.
Advanced Studies in the Technical Colleges

The Crowther Report — through Industrial Eyes
Authors: Hawkins T.H.
Published: November 2014

CAREFUL READING of the Crowther Report — and not just a quick look at the Summary of Conclusions and Recommendations — fills one with admiration for the magnificent way in which the members of the Central Advisory Council for Education (England) have dealt with their terms of reference. Extended courses and examinations for late leavers in secondary modern schools, day‐release classes, sandwich courses, the no‐man's land for those who leave school at 16 and whose continued education often consists of a series of skirmishes with ill‐rewarding evening classes, the role of technical and comprehensive schools, specialisation in sixth forms — all these and other matters are discussed and the discussions lead to firm conclusions about how they may be improved, together with recommendations about how the required teachers of quality and the necessary buildings should be found.
Crowther, Industry and the County Colleges … 2
Authors: MacLennan A.

At least it can be said that the Minister of Education has made definite decisions. Whether the reasoning behind them can be considered valid is another matter, largely dependent on how aware one can be about the pressure groups influencing Government policy at the highest levels. No date has been fixed for raising the school‐leaving age. School buildings will have to be adequate to meet the needs created before a date can be fixed. Time is required for experiments with extended courses, and to gain experience in curriculum planning and teaching methods. The teaching force would have to be expanded rapidly at a time when it is difficult to recruit sufficient student teachers, when the training course is being extended to three years and when the increased birth rate is causing serious problems of over‐sized classes in under‐staffed schools. The first priority is to be the rapid reduction of over‐sized classes. Crowther considered all these situations and exposed the difficulties adequately, but his committee still decided on recommending the raising of the school‐leaving age in one of three stated years. It would be interesting to know what new evidence or what additional wisdom was brought to bear on the Minister which was not available to Crowther either within his committee or from the assessors who were advising the committee. The need for more part‐time day release has been re‐emphasised. The Minister is to discuss with his colleague the Minister of Labour the possibility of granting adolescents up to the age of 18 the right to have day release for further education. The incentive value of this device to recalcitrant industries, firms and employers cannot be taken too seriously. As a gesture it is not really very exciting. Even the least cynical can hardly imagine a dull, under‐motivated youngster from the home of an unskilled manual worker not himself interested in further education, demanding day release from an unsympathetic employer. The Report itself was more realistic and much more in touch with real situations. More day release for further education is absolutely necessary to obtain the best contribution for economic development from the kind of young person who will be the craftsmen and technicians of the next twenty years. Compulsion on employers may run counter to our traditions and to the way we like to do things, but experience has shown that freedom to release does not have the necessary effect. It is more than naive to pretend that further exhortation will change the attitude of any large section of industry not now concerned with supporting the further education by which it lives. Much of industry will continue to take out of the national pool without putting in, until something stronger is introduced than the right of a boy or girl to claim day release. In some ways the suggestion is so unrealistic that it is difficult to understand what it will mean in practice.
