description: Le projet européen ROADMAP vise à accompagner les transitions vers une utilisation prudente et responsable des antibiotiques en élevage. Il mobilise les sciences sociales et l’économie au côté des sciences animales et vétérinaires. Cet article présente les résultats du diagnostic réalisé dans ce cadre en 2020, à partir d’entretiens auprès (i) de 10 vétérinaires ou responsables qualité de cinq organisations de producteurs (OP), d’un transformateur et d’un distributeur, puis (ii) de 18 éleveurs dont la moitié en filière sans antibiotiques (SA). The European project ROADMAP promotes transitions for prudent and responsible antimicrobial use in livestock farming. Besides animal and veterinary sciences, it uses social sciences and economics to analyse the structure of food and drug supply chains, as well as the practices, knowledge and behaviours of stakeholders involved in managing the health of farmed animals. This article presents results of the assessment carried out in this project in 2020, based on interviews with (i) 10 veterinarians or quality managers from five producer organizations (PO), a processor and a retailer, and then (ii) 18 pig farmers, half of them in an antibiotic (AB)-free scheme

description: Benzene is the simplest organic, aromatic hydrocarbon and parent compound of numerous important aromatic compounds. Benzene is a colourless liquid with a characteristic odour and is primarily used in the production of polystyrene. Benzene was first discovered by the English scientist Michael Faraday in 1825 in illuminating gas. In 1834 German chemist Eilhardt Mitscherlich heated benzoic acid with lime and produced benzene. In 1845 German chemist A.W. von Hofmann isolated benzene from coal tar. The structure of benzene has been of interest since its discovery. German chemists Joseph Loschmidt in 1861 and August Kekule von Stradonitz in 1866 independently proposed a cyclic arrangement of six carbons with alternating single and double bonds. Kekule subsequently modified his structural formula to one in which oscillation of the double bonds gave two equivalent structures in rapid equilibrium. In 1931 American chemist Linus Pauling suggested that benzene had a single structure, which was a resonance hybrid of the two Kekule structures.

description: A basic concept to calculate physical features of non-ideal plasmas, such as optical properties, is the spectral function which is linked to the self-energy. We calculate the spectral function for a non-relativistic hydrogen plasma in $GW$-approximation. In order to go beyond $GW$ approximation, we include self-energy and vertex correction to the polarization function in lowest order. Partial compensation is observed. The relation of our approach to $GW$ and $GWΓ$ calculations in other fields, such as the band-structure calculations in semiconductor physics, is discussed. From the spectral function we derive the absorption coefficient due to inverse bremsstrahlung via the polarization function. As a result, a significant reduction of the absorption as compared to the Bethe-Heitler formula for bremsstrahlung is obtained.

description: Discovering alternate methods to treat cancer has been the focus of several investigations. The preventive benefits of β-glucan against liver damage, toxicity, and alteration in antinuclear antibody (ANA), alpha-fetoprotein (AFP), and anti-double strand DNA antibody (anti-dsDNA) caused by Ehrlich ascites carcinoma (EAC) are investigated in this study. A total of 40 mice weighing between 20-25 g, were divided randomly into four groups: the control group, the β-glucan group (200 mg/kg bw/day for two weeks), the EAC group, and the EAC+β-glucan group. The most recent research demonstrated that EAC damaged the liver and increased serum levels of AFP, anti-dsDNA, alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP). However, compared to the control, serum total proteins and albumin levels considerably decreased. EAC therapy with β-glucan enhanced liver structure and function. As a result, it is possible that suggests that β-glucan can help prevent and treat liver toxicity.
​Processing of sub- and supra-second intervals in the primate brain results from the calibration of multiple neuronal oscillators via sensory, motor, and feedback processes
Creators: name: Gupta, Daya
Publisher: name: F1000Research
Year: 2015

description: Processing of time intervals by the brain is critical for our interaction with surroundings. Conscious processing of time intervals predicts movements in a vehicular traffic or the temporal delay in finger movements while playing a musical instrument. Processing of time interval also occurs at a subconscious level, which helps to determine the speed of individual muscle contractions, coordinating our movements. To understand how the brain processes various sub- and supra-second intervals, I have proposed inbuilt neuronal oscillators within various circuits in the brain, which helps to form neuronal clock mechanisms. Proposed oscillators include pacemaker neurons, tonic inputs and, synchronized excitation and inhibition of inter-connected neurons. Time is represented within proposed neuronal clock mechanism by intervals, called ‘sensory moment,' between two spikes or spike bursts produced by oscillators. Outputs from oscillators are processed to generate changes in states of next level of circuits, represented by rates of changes in frequency and/or frequency of neuronal activity, which encode time intervals. Inbuilt oscillators are proposed to be calibrated by the (a) feedback processes (b) input of time intervals resulting from rhythmic external sensory stimulation and (c) synchronous effects of feedback processes and evoked sensory activity. The proposed mechanism of calibration also imposes fluctuations on the regular activity of oscillators. Differences with the pacemaker/accumulator model are discussed, which proposes a separate oscillator with a stable frequency. Multiple calibration mechanisms account for redundancies in the timing mechanisms. Furthermore, abnormal feedback processes associated with motor symptoms could be responsible for the impairment of temporal processing  as seen in schizophrenics.

As an application we verify, up to sign, the conjecture about the comparison of the Milnor-Turaev torsion with the complex valued analytic torsion, for odd dimensional manifolds. This is done along the lines of Burghelea, Friedlander and Kappeler's proof of the Cheeger-Müller theorem.

Οι βασικές συνιστώσες του εκπαιδευτικού συστήματος της Αλβανίας μετά το 1991 είναι η αμφισβήτηση του προηγούμενου εκπαιδευτικού κατεστημένου και η υιοθέτηση ευρωπαϊκών προτύπων. Οι μαθητές από την ελληνική μειονότητα φοιτούν σε αλβανικά σχολεία ή σε ιδιωτικά σχολεία. Κύριο χαραχτηριστικό της παιδείας της ελληνικής μειονότητας αποτελεί αναμφίβλοα η μείωση του αριθμού των μαθητών, με συνέπεια πολλά σχολεία να κλείνουν. Η πλειοψηφία του ενεργού πληθυσμού της ελληνικής μειονότητας έχει πλέον μεταναστεύσει στην Ελλάδα λόγω του χαμηλού εισοδήματος και της φτωχής υποστήριξης από την κυβέρνηση.

description: The objective of this study resulted from the modern needs in the European level of human rights, specifically minorities, the greek minority and the current of immigrants that has turned finally in Albania. The basic components of educational system of Albania afterwords 1991, are the contestation previous educational rendered and the adoption of European models. Main characteristic of education of Greek minority constitues indubitably the reduction of number of students and schools, so that a lot of schools close. The majority of economically active population of greek minority live in Greece. This places serious difficulties in the application of new programs of study in Albania.

description: Mycobacterium tuberculosis, a species of pathogenic bacteria in the Mycobacteriaceae family, is the infectious agent that causes tuberculosis (TB), one of the most progressive bacterial pathogens in human history. The pathogen is the first cause of mortality linked to a single pathogen worldwide, especially in poor and developing countries. There are two clinical manifestations of disease caused by this bacterium: pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB). A single nucleotide polymorphism (SNP) in the human caspase recruitment domaincontaining protein 8 (CARD8) gene of TB infection plays a critical role in the disease progression. Combining this SNP with the CARD8 polymorphism increased the effect, indicating a new link between the CARD8 gene and TB infection. The present study was conducted to determine the association between the polymorphism of the CARD8 gene and EPTB infection in humans. The study included patients (males and females) infected with PTB (n = 50), and EPTB (n = 50), as well as 50 healthy individuals as a control group. Blood samples were collected from all the participants and used to isolate DNA. Using a self-designed nested tetra-primer amplification refractory mutation systempolymerase chain reaction (T-ARMS PCR) assay, the genotypes in CARD8 A/T SNPs were identified. The results showed that there were no significant differences between the types of patients themselves and no significant differences between patients and healthy individuals in the results of ARMS-PCR. The findings of the present study revealed a correlation between patients with EPTB and polymorphisms in CARD8 (rs2043211).

description: The established way of interfacing with most computer systems is a mouse and keyboard. Hand gestures are an intuitive and effective touchless way to interact with computer systems. However, hand gesture based systems have seen low adoption among end-users primarily due to numerous technical hurdles in detecting in-air gestures accurately. This paper presents Gestop, a framework developed to bridge this gap. The framework learns to detect gestures from demonstrations, is customizable by end-users and enables users to interact in real-time with computers having only RGB cameras, using gestures.

Evaluating causal discourse in academic writing
Creators: name: Slater, Tammy Jayne Anne
Publisher: name: University of British Columbia
Year: 2009

description: According to the Canale and Swain model of language evaluation (1979, 1980), discourse can be assessed in an integrative manner using their theoretical framework of communicative competence, yet this framework, which reflects Chomsky's 1965 notion of competence as the knowledge of language rules, offers only a taxonomy of elements without showing how these elements can be integrated. In sharp contrast to this is systemic functional linguistics, which views language as resource. According to Halliday and Martin (1993), speakers of a language use a variety of language features to construct meaning. These authors examined the causal line in scientific writing and established a clear example of the integration of form and function. This qualitative study attempts to discover whether Canale and Swain's framework is able to evaluate texts which demonstrate the integration of form, meaning, and the visual line. To do this, discourse samples were collected from fifty participants who wrote accounts of the water cycle using a visual prompt. Twenty-seven of these accounts were discussed in two small focus groups, and from these twenty-seven, five samples were rated using an assessment instrument based on Canale and Swain, and analyzed using a discourse analysis tool presented in Veel (forthcoming). The following questions were asked: 1. Can readers intuitively detect differences in the quality of descriptions written using a visual prompt, and can they notice the relationship between the discourse and the visual prompt? 2. Can readers using an assessment instrument based on the Canale and Swain theoretical framework assess the quality of descriptions written using a visual prompt, and can they notice the relationship between the discourse and the visual prompt? 3. Can a Hallidayan functional analysis illuminate the quality of the descriptions and address the relationship between the discourse and the visual prompt? The findings raise questions about the assumptions of the Canale and Swain framework as a model for assessing differences in the quality of academic writing, and recommend instead the examination of systemic functional linguistics as a framework for teaching and assessing academic language.

description: A tensegrity tower design to support a given payload for the moon mining operation is proposed in this paper. A non-linear optimization problem for the minimal-mass structure design is posed and solved, subject to the yielding constraints for strings and yielding and buckling constraints for bars in the presence of lunar gravity. The optimization variables for this non-linear problem are structural complexity and pre-stress in the strings. Apart from local failure constraints of yielding and buckling, global buckling is also considered. The structure designed as a deployable tower is a TnD1 tensegrity structure. A case study demonstrates the feasibility and advantage of the tower design. The principles developed in this paper are also applicable for building other structures on the Earth or other planets.

description: In this paper we have considered the problem of parametric sound generation in an acoustic resonator flled with a fluid, taking explicitely into account the influence of the nonlinearly generated second harmonic. A simple model is presented, and its stationary solutions obtained. The main feature of these solutions is the appearance of bistable states of the fundamental field resulting from the coupling to the second harmonic. An experimental setup was designed to check the predictions of the theory. The results are consistent with the predicted values for the mode amplitudes and parametric thresholds. At higher driving values a self-modulation of the amplitudes is observed. We identify this phenomenon with a secondary instability previously reported in the frame of the theoretical model.

description: The aim: determination of correlation dependence of adaptogenic defense reactions in rats in the acute phase of pain stress on laser-puncture exposure to low-intensity IR radiation. Material and methods. Four groups of rats were used in the work: "experimental", which received after the injury a 10-day course of PPBM, and three comparison groups ("intact", "no exposure" and "placebo"). The intensity of lipid peroxidation, specific activity of antioxidant enzymes, protein concentration, malonic dialdehyde content in blood plasma and erythrocytes were determined by spectrophotometric method. Microcirculation indices were evaluated according to the previous series of our studies. Emotional and behavioral reactions were studied in the "open field" test. Results. Normalization of metabolic, microcirculatory and behavioral indices was registered in the experimental group. The correlation coefficients between the microcirculation index and the data of behavioral activity under pain stress were significantly less than the correlation coefficients between oxidative stress and cognitive functions, which confirms the determining role of oxidative metabolism disturbance in the formation of cognitive disorders. Conclusion: the registered adaptation and stress-limiting effect of PPBM in conditions of experimental pain stress allows us to recommend the technology of laser acupuncture for use in complex rehabilitation of patients with pain syndrome.

description: A recently proposed model of non-autocatalytic reactions in dipeptide reactions leading to spontaneous symmetry breaking and homochirality is examined. The model is governed by activation, polymerization, epimerization and depolymerization of amino acids. Symmetry breaking is primarily a consequence of the fact that the rates of reactions involving homodimers and heterodimers are different, i.e., stereoselective, and on the fact that epimerization can only occur on the N-terminal residue and not on the Cterminal residue. This corresponds to an auto-inductive cyclic process that works only in one sense. It is argued that epimerization mimics both autocatalytic behavior as well as mutual antagonism - both of which were known to be crucial for producing full homochirality.

description: Background: the nucleus pulposus NP pulls on the ruptured annulus fibrosus AF, bulging the intervertebral disc IVD and releasing chemicals that may irritate nerves and cause inflammation and pain. This produces histological changes to the IVD, including less gelatinous NP, cracks and fissures, decreased matrix water content, and proteoglycan composition changes. Aim of study: this study aims to investigate the histopathological changes in the Herniated Disc HD tissue, as well as cartilage histopathology grade and stage assessment. Materials and methods: fourty tissue samples of lumbar HD obtained after the operations were kept in 10% formalin. Then all HD sections were processed, and embedded, after that, 5 μm thick glass mounted sections were stained with Hematoxylin and Eosin and Alcian blue (pH 0.02) and examined microscopically for histopathological changes and grading scoring was also conducted based on cell density, structural alterations of collagen fibers, and proteoglycan degeneration. Results: hemorrhage with fibrin deposition, mucous degeneration around chondrocyte clones and degeneration, increased chondrocyte density, expanded lacunae with degenerated chondrocytes, fiber disorientation, cleft formation, mucoid matrix changes, and inflammatory cell infiltration with fibrocyte prefiltration were the most histopathological changes in HD samples. Along with necrotic chondrocyte increase and tissue fiber alterations. Histological cell density grade indicated different-sized clones. All HD tissues revealed collagen fiber structural alterations, with gradients (52.5%) being most common. All HD samples showed mucous (proteoglycans) degradation, especially in gradients abundantly present and intermediate between 1 and 3 (45% and 42.5%). Conclusions: histopathological changes in intervertebral disc associated with HD infection.

description: Background: previous studies have implicated the INSIG2 rs6726538 single nucleotide polymorphism (SNP) as a potential risk factor for cervical cancer. Our objective was to examine the correlation between this genetic variation and the vulnerability of Iraqi women to cervical cancer. Methods: this case-control study analyzed rs6726538 genotypes and allele frequencies in 109 cervical cancer cases and 109 healthy controls. Logistic regression calculated odds ratios (OR) and 95% confidence intervals (CI). The rs6726538 SNP was genotyped using tetra-primer ARMS-PCR. Results: the AT genotype occurred more frequently in cases than controls (52.2% vs 34%, OR 0.783, 95% CI 0.38-1.25, p = 0.0391). The TT genotype was less common but showed a non-significant decreased cancer risk versus AA (OR 0.336, 95% CI 0.17-0.96, p = 0.0707). The T allele was significantly higher in cases (36.3% vs 20.6% in controls, p = 0.0023), while the A allele was higher in controls (79.4% vs 63.7% in cases, p = 0.05). Conclusion: this preliminary data indicates that the rs6726538 T allele and TT genotype may be associated with increased cervical cancer risk, while the A allele and AA genotype could have a protective effect. However, larger studies are required to validate these initial findings on how this SNP may impact cervical cancer susceptibility.

description: Domain walls, topological defects that define the frontier between regions of different stacking in multilayer graphene, have proved to host exciting physics. The ability of tuning these topological defects in-situ in an electronic transport experiment brings a wealth of possibilities in terms of fundamental understanding of domain walls as well as for electronic applications. Here, we demonstrate through a MEMS (micro-electromechanical system) actuator and magnetoresistance measurements the effect of domain walls in multilayer graphene quantum Hall effect. Reversible and controlled uniaxial strain triggers these topological defects, manifested as new quantum Hall effect plateaus as well as a discrete and reversible modulation of the current across the device. Our findings are supported by theoretical calculations and constitute the first indication of the in-situ tuning of topological defects in multilayer graphene probed through electronic transport, opening the way to the use of reversible topological defects in electronic applications.

Methoxamine increased the duration of the repolarization phase of the action potential. However, there were no changes in the other electrophysiological parameters studied. U-73122 markedly blocked all effects of α1-adrenoreceptor stimulation on the parameters of the electrical activity of working cardiomyocytes in 7-, 21-, and 100-day-old rats.

description: A varicocele is the most common rectification cause of male infertility. It is an abnormal dilation of the veins of the pampiniform plexus in the spermatic cord. It is estimated to affect 10-15% of men and adolescents. The aim of the current study was to investigate the immunological parameters, gene expression profiles, and their correlations in varicocele and non-varicocele oligospermic patients compared to healthy controls, providing insights into the molecular mechanisms underlying male infertility. A total of 120 males were involved in this study over the period from October 2023 to January 2024. Blood and semen samples were collected from patients who were diagnosed with varicocele confirmed oligospermia (40 samples) and non-varicocele oligospermic patients (40 samples), in addition to 40 apparently healthy males as control. The level of IL-18 and IL-37 was estimated in the serum of tested groups using Enzyme Linked Immunosorbent Assay (ELISA) technique. The serum levels of the pro-inflammatory cytokine IL-18 were significantly elevated in all patient groups compared with control. Interestingly, the anti-inflammatory cytokine IL-37 was also significantly increased. The gene expression of heat shock protein A2 (HSPA2) was detected using reverse transcriptase polymerase chain reaction (RT-PCR). The fold of gene expression results by RT-PCR technique revealed a significant downregulation of HSPA2 (0.3453 ± 0.311-fold) gene expression in varicocele patients and a 0.154 ± 0.13fold decrease in non-varicocele oligospermia compared with control. However, no significant correlation was found between the expression of HSPA2 and the levels of IL-18 and IL-37.

description: We study the out-of-equilibrium current through an interacting quantum dot modelled as an Anderson impurity contacted by two BCS superconductors held at fixed voltage bias. In order to account for multiple Andreev reflections, we develop a Keldysh Green's function scheme perturbative in the dot's interaction strength. We find an unexpected enhancement of the current due to repulsive interactions for small lead-to-dot couplings.

description: Hexagonal boron nitride (h-BN) is well-established as a requisite support, encapsulant and barrier for 2D material technologies, but also recently as an active material for applications ranging from hyperbolic metasurfaces to room temperature single-photon sources. Cost-effective, scalable and high quality growth techniques for h-BN layers are critically required. We utilise widely-available iron foils for the catalytic chemical vapour deposition (CVD) of h BN and report on the significant role of bulk dissolved species in h-BN CVD, and specifically, the balance between dissolved oxygen and carbon. A simple pre-growth conditioning step of the iron foils enables us to tailor an error-tolerant scalable CVD process to give exceptionally large h-BN monolayer domains. We also develop a facile method for the improved transfer of as-grown h-BN away from the iron surface by means of the controlled humidity oxidation and subsequent rapid etching of a thin interfacial iron oxide; thus, avoiding the impurities from the bulk of the foil. We demonstrate wafer-scale (2 inch) production and utilise this h-BN as a protective layer for graphene towards integrated (opto) electronic device fabrication.

Vortex tilt modulus in Fulde-Ferrell-Larkin-Ovchinnikov state

description: Vortex tilt response in Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) vortex lattice is theoretically examined as a probe reflecting the spatial structure of this state. In the FFLO state with nodal planes perpendicular to the magnetic field in a quasi 2D material under a parallel field, the tilt modulus E_{2} {\it of the nodal planes} decreases as the paramagnetic effect is effectively enhanced, and this reduction of E_{2} in turn reduces the vortex tilt modulus. This reduction of vortex tilt modulus, more remarkable in more anisotropic systems, accompanying the FFLO transition may be an origin of the monotonous reduction of sound velocity detected upon cooling in a ultrasound measurement for CeCoIn5.

description: Benzene is an organic chemical compound. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of chemicals with more complex structure, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Modern bonding models (valence-bond and molecular orbital theories) explain the structure and stability of benzene in terms of delocalization of six of its electrons, where delocalization in this case refers to the attraction of an electron by all six carbons of the ring instead of just one or two of them. This delocalization causes the electrons to be more strongly held, making benzene more stable and less reactive than expected for an unsaturated hydrocarbon. As a result, the hydrogenation of benzene occurs somewhat more slowly than the hydrogenation of alkenes (other organic compounds that contain carbon-carbon double bonds), and benzene is much more difficult to oxidize than alkenes. Most of the reactions of benzene belong to a class called electrophilic aromatic substitution that leave the ring itself intact but replace one of the attached hydrogens. These reactions are versatile and widely used to prepare derivatives of benzene.

description: A hypothesis is proposed about the role of evolutionary relationship of retroelements with transfer RNAs (tRNAs) on their processing to form small non-coding RNAs. This is evidenced by the use of tRNA as primers for reverse transcriptase, origin of SINE2 from tRNA, use of LINE1 enzymes by tRNA for pseudogenes formation. Under the influence of RISC enzymes, tRFs are formed from tRNA, that control gene expression at the epigenetic level. Noncoding RNAs formed from transcripts of retroelements are characterized by similar properties. An assumption has been made about the functioning of a species-specific epigenetic network between such non-coding RNAs formed from retroelements and tRNAs. Decoding such a network may open up the possibility of creating new epigenetic agents for the treatment of human diseases, and will also allow us to determine mechanisms of genetic code emergence in evolution. One of the bases for this network formation may be the distribution and composition of tRNAs and retroelements in the genome. I have provided data on this network mechanisms formation, describing the similar functional properties of tRNAs and retroelements, their influence on the same targets and pathways in the human organism. I suppose that the relationship between tRNAs and retroelements arose as an integral property of living things when life arose in RNA world, where tRNAs were originally used to perform many regulatory catalytic functions, one of which was later transformed into the transfer of amino acids for protein synthesis.

description: This paper develops a category-theoretic approach to uncertainty, informativeness and decision-making problems. It is based on appropriate first order fuzzy logic in which not only logical connectives but also quantifiers have fuzzy interpretation. It is shown that all fundamental concepts of probability and statistics such as joint distribution, conditional distribution, etc., have meaningful analogs in new context. This approach makes it possible to utilize rich conceptual experience of statistics. Connection with underlying fuzzy logic reveals the logical semantics for fuzzy decision making. Decision-making problems within the framework of IT-categories and generalizes Bayesian approach to decision-making with a prior information are considered. It leads to fuzzy Bayesian approach in decision making and provides methods for construction of optimal strategies.

Work smarter not faster: an investigation into English as a second language training for garment workers in a union setting
Creators: name: Trebble, Maggi
Publisher: name: University of British Columbia
Year: 2009

description: This study investigates an English as a second language training program for garment workers initiated by a union, for its members and non-union workers. It is a case study based on one particular English language training in the workplace program, provided as a partnership between a union and the labour studies program of a community college. The research objective of the study was to identify and analyze significant factors related to: (1) the union's perceived need to establish English in the workplace (EWP) classes and the impact of such a program on the union, (2) the perceived need and impact of the classes on the participants, both union and non-union workers and, (3) as a secondary consideration, the impact of the program on the company, the teachers and the college. The issues were examined through an investigation of the perceptions of the union, the participants, the company, the teachers and the college. The study used a qualitative research design and ethnographic and participatory research methods were employed from an insider perspective, to facilitate the gathering of data. Particular attention was paid to the role of the union in providing English as a second language (ESL) classes to garment workers, as this was a unique factor in the delivery of the program. The implications of the study for practice include; recognition of barriers to learning and using English, a knowledge of the culture of the work place and the setting where the classes occur, as well as a knowledge of the other stakeholders involved in the program. The implications for pedagogy include issues related to; the development of appropriate content, teacher education, and the role of the teachers and the college in providing such a program. This study illuminates many critical aspects in the perceptions of union officials, garment workers, the teachers and the company, regarding the need and impact of an English in the workplace training program.
