621.31 - Abstract
State-of-the-art Density Functional Theory calculations are employed in the investigation of a number of processes occurring at the anode and cathode of Alkaline Fuel Cells for a variety of electrocatalyst materials. In the case of the methanol oxidation reaction, at the anode, the investigation is carried out with a view to quantitatively resolving the nature of the surface adsorbate on Pt(211) and is executed in combination with a cluster-continuum model approach, the principal adsorbate is found to be a methanol-OH complex. At the cathode, the oxygen reduction reaction is studied for the purpose of obtaining complete mechanistic understanding in the free energy landscape, thereby enabling the elucidation of the potential-determining step and, furthermore, the theoretical prediction of the onset potential. The oxygen reduction reaction is thus studied upon a range of cobalt oxide surfaces, and for a variety of Pt-WC catalysts, in addition to pure Pt(111}. The results obtained show good agreement with experiment, where appropriate. Furthermore, they highlight the need for detailed mechanistic studies in order to predict and explain experimental results since simplified, single-descriptor, approaches may sometimes result in misleading predictions.

Medicine - Abstract
BackgroundOne in 10 people in the United Kingdom will need a total knee replacement (TKR) during their lifetime. Access to this life-changing operation has recently been restricted based on body mass index (BMI) due to belief that high BMI may lead to poorer outcomes. We investigated the associations between BMI and revision surgery, mortality, and pain/function using what we believe to be the world's largest joint replacement registry.Methods and findingsWe analysed 493,710 TKRs in the National Joint Registry (NJR) for England, Wales, Northern Ireland, and the Isle of Man from 2005 to 2016 to investigate 90-day mortality and 10-year cumulative revision. Hospital Episodes Statistics (HES) and Patient Reported Outcome Measures (PROMs) databases were linked to the NJR to investigate change in Oxford Knee Score (OKS) 6 months postoperatively. After adjustment for age, sex, American Society of Anaesthesiologists (ASA) grade, indication for operation, year of primary TKR, and fixation type, patients with high BMI were more likely to undergo revision surgery within 10 years compared to those with "normal" BMI (obese class II hazard ratio (HR) 1.21, 95% CI: 1.10, 1.32 (p < 0.001) and obese class III HR 1.13, 95% CI: 1.02, 1.26 (p = 0.026)). All BMI classes had revision estimates within the recognised 10-year benchmark of 5%. Overweight and obese class I patients had lower mortality than patients with "normal" BMI (HR 0.76, 95% CI: 0.65, 0.90 (p = 0.001) and HR 0.69, 95% CI: 0.58, 0.82 (p < 0.001)). All BMI categories saw absolute increases in OKS after 6 months (range 18-20 points). The relative improvement in OKS was lower in overweight and obese patients than those with "normal" BMI, but the difference was below the minimal detectable change (MDC; 4 points). The main limitations were missing BMI particularly in the early years of data collection and a potential selection bias effect of surgeons selecting the fitter patients with raised BMI for surgery.ConclusionsGiven revision estimates in all BMI groups below the recognised threshold, no evidence of increased mortality, and difference in change in OKS below the MDC, this large national registry shows no evidence of poorer outcomes in patients with high BMI. This study does not support rationing of TKR based on increased BMI.

Medicine - Abstract
BackgroundNearly 100,000 people underwent total hip replacement (THR) in the United Kingdom in 2018, and most can expect it to last at least 25 years. However, some THRs fail and require revision surgery, which results in worse outcomes for the patient and is costly to the health service. Variation in the survival of THR implants has been observed between units and reducing this unwarranted variation is one focus of the "Getting it Right First Time" (GIRFT) program in the UK. We aimed to investigate whether the statistically improved implant survival of THRs in a high-performing unit is associated with the implants used or other factors at that unit, such as surgical skill.Methods and findingsWe analyzed a national, mandatory, prospective, cohort study (National Joint Registry for England, Wales, Northern Ireland and the Isle of Man [NJR]) of all THRs performed in England and Wales. We included the 664,761 patients with records in the NJR who have received a stemmed primary THR between 1 April 2003 and 31 December 2017 in one of 461 hospitals, with osteoarthritis as the only indication. The exposure was the unit (hospital) in which the THR was implanted. We compared survival of THRs implanted in the "exemplar" unit with THRs implanted anywhere else in the registry. The outcome was revision surgery of any part of the THR construct for any reason. Net failure was calculated using Kaplan-Meier estimates, and adjusted analyses employed flexible parametric survival analysis. The mean age of patients contributing to our analyses was 69.9 years (SD 10.1), and 61.1% were female. Crude analyses including all THRs demonstrated better implant survival at the exemplar unit with an all-cause construct failure of 1.7% (95% CI 1.3-2.3) compared with 2.9% (95% CI 2.8-3.0) in the rest of the country after 13.9 years (log-rank test P < 0.001). The same was seen in analyses adjusted for age, sex, and American Society of Anesthesiology (ASA) score (difference in restricted mean survival time 0.12 years [95% CI 0.07-0.16; P < 0.001]). Adjusted analyses restricted to the same implants as the exemplar unit show no demonstrable difference in restricted mean survival time between groups after 13.9 years (P = 0.34). A limitation is that this study is observational and conclusions regarding causality cannot be inferred. Our outcome is revision surgery, and although important, we recognize it is not the only marker of success of a THR.ConclusionsOur results suggest that the "better than expected" implant survival results of this exemplar center are associated with implant choice. The survival results may be replicated by adopting key treatment decisions, such as implant selection. These decisions are easier to replicate than technical skills or system factors.

Morrison, James L. and Ashley, William C.
- Abstract
This handbook was designed to accompany a three-day workshop for senior administrators in higher education on proactive management techniques in higher education. Proactive management allows for anticipating change and managing uncertainty in place of crisis management or reactive actions. The workshop covered: (1) strategic thinking; (2) outside-in thinking (with examples from the corporate world); (3) how to establish a strategic trend intelligence system (steps include developing a program structure, developing a scanning taxonomy, organizing files electronically, identifying literature sources and data bases, assigning scanners to information resources, training scanners, training abstractors, using scanning newsletters and issue briefs); (4) doing an environmental vulnerability audit (steps include identifying institutional underpinnings, identifying developments that could damage those underpinnings, evaluating the likelihood of impact of these developments, reviewing threat patterns); and (5) issues management: the role of decision (discussing implementation steps, strategy support requirements, selecting strategies, and implementation). Several worksheets for completion during the seminar are included. Also included are over 200 references and the following 5 appendixes: "Environmental Scanning at the Georgia Center for Continuing Education: A Progress Report"; an environmental scanning notebook; an issue of "Lookouts: Newsletter of Environmental Scanning of the Georgia Center for Continuing Education"; a summary of future concerns as scanned by Cardinal Stritch College (Wisconsin) and information on the seminar leaders.

- Abstract
Prasugrel, a potent P2Y
12 receptor inhibitor, is not currently recommended in patients with stroke due to a higher rate of recurrent stroke. Prasugrel was associated with comparable efficacy to clopidogrel in reducing the risk of ischemic stroke in a recent phase III study. The authors provide an overview of the potential role of prasugrel in the management of ischemic stroke. The authors searched PUBMED, MEDLINE, and clinicaltrials.org and recently presented trials at the conferences for clinical trials of prasugrel therapy in patients with stroke and TIA, and important original investigations are reviewed. The recent PRASTRO-trials demonstrated comparable outcomes of lower maintenance dose (3.5 mg daily dose) with clopidogrel in East Asian stroke patients, thus can be a credible option as a P2Y12 receptor inhibitor. It can also be considered as a credible option in other races and ethnicities and in other clinical situations that may require DAPT, such as intracranial or carotid stenting. Since prasugrel is associated with a superior antiplatelet effect and is not influenced by genetic polymorphisms, there is no need for platelet function or genetic testing. More work is needed to establish the safety and efficacy of low-dose prasugrel plus aspirin in comparison with currently used clopidogrel plus aspirin in non-East Asian populations.

Developmental dysplasia of the hip (DDH) describes the abnormal development of a hip in childhood, ranging from complete dislocation of the hip joint to subtle immaturity of a hip that is enlocated and stable within the socket. DDH occurs in around 10 per 1000 live births, though only one per 1000 are completely dislocated. There is variation in treatment pathways for DDH, which differs between hospitals and even between clinicians within the same hospital. The variation is related to the severity of dysplasia that is believed to require treatment, and the techniques used to treat dysplasia.To determine the effectiveness of splinting and the optimal treatment strategy for the non-operative management of DDH in babies under six months of age.We searched CENTRAL, MEDLINE, Embase, seven other electronic databases, and two trials registers up to November 2021. We also checked reference lists, contacted study authors, and handsearched relevant meetings abstracts.Randomised controlled trials (RCTs), including quasi-RCTs, as well as non-RCTs and cohort studies conducted after 1980 were included. Participants were babies with all severities of DDH who were under six months of age. Interventions included dynamic splints, static splints or double nappies (diapers), compared to no splinting or delayed splinting.Two review authors independently selected studies, extracted data and performed risk of bias and GRADE assessments. The primary outcomes were: measurement of acetabular index at years one, two and five, as determined by radiographs (angle): the need for operative intervention to achieve reduction and to address dysplasia; and complications. We also investigated other outcomes highlighted by parents as important, including the bond between parent and child and the ability of mothers to breastfeed.We included six RCTs or quasi-RCTs (576 babies). These were supported by 16 non-RCTs (8237 babies). Five studies had non-commercial funding, three studies stated 'no funding' and 14 studies did not state funding source. The RCTs were generally at unclear risk of bias, although we judged three RCTs to be at high risk of bias for incomplete outcome data. The non-RCTs were of moderate and critical risk of bias. We did not undertake meta-analysis due to methodological and clinical differences between studies; instead, we have summarised the results narratively. Dynamic splinting versus delayed or no splinting Four RCTs and nine non-RCTs compared immediate dynamic splinting and delayed dynamic splinting or no splinting. Of the RCTs, two considered stable hips and one considered unstable (dislocatable) hips and one jointly considered unstable and stable hips. No studies considered only dislocated hips. Two RCTs (265 babies, very low-certainty evidence) reported acetabular index at one year amongst stable or dislocatable hips. Both studies found there may be no evidence of a difference in splinting stable hips at first diagnosis compared to a strategy of active surveillance: one reported a mean difference (MD) of 0.10 (95% confidence interval (CI) -0.74 to 0.94), and the other an MD of 0.20 (95% CI -1.65 to 2.05). Two RCTs of stable hips (181 babies, very low-certainty evidence) reported there may be no evidence of a difference between groups for acetabular index at two years: one study reported an MD of -1.90 (95% CI -4.76 to 0.96), and another study reported an MD of -0.10 (95% CI -1.93 to 1.73), but did not take into account hips from the same child. No study reported data at five years. Four RCTs (434 babies, very low-certainty evidence) reported the need for surgical intervention. Three studies reported that no surgical interventions occurred. In the remaining study, two babies in the dynamic splinting group developed instability and were subsequently treated surgically. This study did not explicitly state if this treatment was to achieve concentric reduction or address residual dysplasia. Three RCTs (390 babies, very low-certainty evidence) reported no complications (avascular necrosis and femoral nerve palsy). Dynamic splinting versus static splinting One RCT and five non-RCTs compared dynamic versus static splinting. The RCT (118 hips) reported no occurrences of avascular necrosis (very low-certainty evidence) and did not report radiological outcomes or need for operative intervention. One quasi-RCT compared double nappies versus delayed or no splinting but reported no outcomes of interest. Other comparisons No RCTs compared static splinting versus delayed or no splinting or staged weaning versus immediate removal.There is a paucity of RCT evidence for splinting for the non-operative management of DDH: we included only six RCTs with 576 babies. Moreover, there was considerable heterogeneity between the studies, precluding meta-analysis. We judged the RCT evidence for all primary outcomes as being of very low certainty, meaning we are very uncertain about the true effects. Results from individual studies provide limited evidence of intervention effects on different severities of DDH. Amongst stable dysplastic hips, there was no evidence to suggest that treatment at any stage expedited the development of the acetabulum. For dislocatable hips, a delay in treatment onset to six weeks does not appear to result in any evidence of a difference in the development of the acetabulum at one year or increased risk of surgery. However, delayed splinting may reduce the number of babies requiring treatment with a harness. No RCTs compared static splinting with delayed or no splinting, staged weaning versus immediate removal or double nappies versus delayed or no splinting. There were few operative interventions or complications amongst the RCTs and the non-randomised studies. There's no apparent signal to indicate a higher frequency of either outcome in either intervention group. Given the frequency of this disease, and the fact that many countries undertake mandatory DDH screening, there is a clear need to develop an evidence-based pathway for treatment. Particular uncertainties requiring future research are the effectiveness of splinting amongst stable dysplastic hips, the optimal timing for the onset of splinting, the optimal type of splint to use and the need for 'weaning of splints'. Only once a robust pathway for treatment is established, can we properly assess the cost-effectiveness of screening interventions for DDH.

Orthopedic surgery ,RD701-811 - Abstract
Background and purpose — To further improve the success of joint replacement surgery, attention needs to be paid to variations associated with improved or worsened outcomes. We investigated the association between the type of bone cement used and the risk of revision surgery after primary total hip replacement. Methods — We conducted a prospective study of data from the National Joint Registry for England and Wales between April 1, 2003 and December 31, 2013. 199,205 primary total hip replacements performed for osteoarthritis where bone cement was used were included. A multilevel over-dispersed piecewise Poisson model was used to estimate differences in the rate of revision by bone cement type adjusted for implant type, head size, age, sex, ASA grade, and surgical approach. Results — The rate of revision was higher in DePuy CMW3 medium viscosity with gentamicin (IRR 2.0, 95% CI 1.5–2.7) and DePuy SmartSet high viscosity plain (IRR 2.7, 95% CI 1.1–5.5), and lower in DePuy CMW1 high viscosity plain (IRR 0.44, 95% CI 0.19–0.89) bone cements compared with Heraeus Palacos high viscosity with gentamicin. Revision rates were similar between plain and antibiotic-loaded bone cement. Interpretation — The majority of bone cements performed similarly well, excluding DePuy SmartSet high viscosity and CMW3 high viscosity with gentamicin, which both had higher revision rates. We found no clear differences by viscosity or antibiotic content.

Medicine - Abstract
Objectives For many people with advanced osteoarthritis, total knee replacement (TKR) is an effective treatment for relieving pain and improving function. Features of perioperative care may be associated with the adverse event of chronic pain 6 months or longer after surgery; effects may be direct, for example, through nerve damage or surgical complications, or indirect through adverse events. This systematic review aims to evaluate whether non-surgical perioperative interventions prevent long-term pain after TKR.Methods We conducted a systematic review of perioperative interventions for adults with osteoarthritis receiving primary TKR evaluated in a randomised controlled trial (RCT). We searched The Cochrane Library, MEDLINE, Embase, PsycINFO and CINAHL until February 2018. After screening, two reviewers evaluated articles. Studies at low risk of bias according to the Cochrane tool were included.Interventions Perioperative non-surgical interventions; control receiving no intervention or alternative treatment.Primary and secondary outcome measures Pain or score with pain component assessed at 6 months or longer postoperative.Results 44 RCTs at low risk of bias assessed long-term pain. Intervention heterogeneity precluded meta-analysis and definitive statements on effectiveness. Good-quality research provided generally weak evidence for small reductions in long-term pain with local infiltration analgesia (three studies), ketamine infusion (one study), pregabalin (one study) and supported early discharge (one study) compared with no intervention. For electric muscle stimulation (two studies), anabolic steroids (one study) and walking training (one study) there was a suggestion of more clinically important benefit. No concerns relating to long-term adverse events were reported. For a range of treatments there was no evidence linking them with unfavourable pain outcomes.Conclusions To prevent chronic pain after TKR, several perioperative interventions show benefits and merit further research. Good-quality studies assessing long-term pain after perioperative interventions are feasible and necessary to ensure that patients with osteoarthritis achieve good long-term outcomes after TKR.

31. The Efficacy of Learning Communities in Assisting Developmental Students in Achieving Graduation and Accumulation of Credit Hours in a Southern Metropolitan Community College

Ashley, William J.
- Abstract
Hinds Community College (HCC) engaged in a study that produced the transitional program. This program was in response to high rates of attrition of the college's freshmen classes because of poor academic performance. This dissertation evaluated the effectiveness of the transitional program's main component-the learning community created by placing students in the LLS 1151 College Life course based on their status as residence hall students. HCC's transitional program is a further elaboration of placement policies that have been a part of the community college landscape for many years. The HCC transitional program incorporates learning communities in combination with HCC's placement policies and provides an element of structure. This research examined the academic progress of a cohort from its inception in the fall semester of 2006 through 4 years until the conclusion of the spring 2010 semester. This examination included a review and analysis of the performance of the transitional program students who were assigned to learning communities as opposed to the performance of developmental students who were not assigned to learning communities (those who commuted). Specifically, the research evaluated how many students completed programs of study out of those who initially enrolled as residential transitional students and out of those who initially enrolled as nonresidential transitional students, how many credit hours the two groups accumulated over a 4-year period, and performance in basic English and mathematics courses. This study used a causal-comparative design that examined a cohort over a 4-year period while at HCC to examine if there were significant differences between those students who were a part of a learning community compared to those students who were not.

- Abstract
Developmental dysplasia of the hip (DDH) describes the abnormal development of a hip in childhood, ranging from complete dislocation of the hip joint to subtle immaturity of a hip that is enlocated and stable within the socket. DDH occurs in around 10 per 1000 live births, though only one per 1000 are completely dislocated. There is variation in treatment pathways for DDH, which differs between hospitals and even between clinicians within the same hospital. The variation is related to the severity of dysplasia that is believed to require treatment, and the techniques used to treat dysplasia. To determine the effectiveness of splinting and the optimal treatment strategy for the non-operative management of DDH in babies under six months of age. We searched CENTRAL, MEDLINE, Embase, seven other electronic databases, and two trials registers up to November 2021. We also checked reference lists, contacted study authors, and handsearched relevant meetings abstracts. Randomised controlled trials (RCTs), including quasi-RCTs, as well as non-RCTs and cohort studies conducted after 1980 were included. Participants were babies with all severities of DDH who were under six months of age. Interventions included dynamic splints, static splints or double nappies (diapers), compared to no splinting or delayed splinting. Two review authors independently selected studies, extracted data and performed risk of bias and GRADE assessments. The primary outcomes were: measurement of acetabular index at years one, two and five, as determined by radiographs (angle): the need for operative intervention to achieve reduction and to address dysplasia; and complications. We also investigated other outcomes highlighted by parents as important, including the bond between parent and child and the ability of mothers to breastfeed. We included six RCTs or quasi-RCTs (576 babies). These were supported by 16 non-RCTs (8237 babies). Five studies had non-commercial funding, three studies stated 'no fundin

- Abstract
This guide is one of three developed to provide guidelines, information, and resources useful in planning and developing postsecondary technician training programs in high technology. It is specifically intended for program planners and developers in the initial stages of planning a new program or specialized option in robotics. (Two companion guides offer a set of generalizable procedures for systematic program development in high technology and curricular information for planning a computer-aided design, computer-aided manufacturing training program.) The first part reviews the problem, objectives, methods, and outcomes of the project. Information is presented in the second part on industry trends in robotic technology, current projects in industry and education, and the need for training. Part 3 presents curriculum planning guidelines and specifications. Lists of technician-level competencies and sample course titles and course descriptions are provided. Other factors that must be considered in developing and implementing a new program are discussed, including special training for application processes, equipment requirements, faculty capabilities, and future trends. Appendixes include a compilation of site visits by project staff, a list of robot manufacturers and postsecondary programs, a bibliography of robotic technical papers, and a paper on robotics training.

- Abstract
This report, one in a series of three publications for vocational program developers and others to use in planning and developing a community-based response to worker dislocation, deals with programs for dislocated workers that have been developed and supported by private sector and local community efforts and resources. Reviewed in the first chapter are various services that are often needed by dislocated workers, including income assistance, outplacement services, out-training, job search skill training, evaluation and assessment services, counseling services, relocation assistance, and retraining services. The second chapter deals with the context, purpose, organizational characteristics, program characteristics, and outcomes of three community-based dislocated worker assistance programs. These programs are Project RENEW: A Manpower Assistance Program for Displaced Workers, the Metropolitan Reemployment Project, and the Dislocated Workers Education Training Program. Examined in the final chapter are six sample preventative, layoff, and postlayoff strategies that have been used by individual companies to alleviate the problems of dislocated workers. Profiles of 35 other displaced worker assistance programs are appended. (MN)

- Abstract
Designed primarily as a basic reference to assist researchers and planners in the study of factors related to occupational mobility and skill transfer within and between occupations, this catalog consists of two major sections. Section 1 contains the abstracts of the data bases. These abstracts include selected key variables organized in a standard format and are intended to present the reader with sufficient information to enable him/her to determine if any of the data bases are appropriate to their needs and warrant further examination. The abstract format of the data bases includes the following: data base title, principal investigator, documentation, access, design information, subject variables, and occupational variables. Section 2 contains the abstracts of classification schemes. The classification scheme abstract format is designed to facilitate the use of the classification schemes in organizing information from the data bases to give a variety of new perspectives on occupational mobility and occupational skill transfer. The abstract format for the classification schemes includes the following: scheme title, design information, classification variables, and outcomes/products. Appended are lists of the identified data bases and of data base abstracts by principal investigator, data base worksheet, classification scheme worksheet, and a data base cross reference index. (SH)

Ohio State Univ., Columbus. National Center for Research in Vocational Education. and Ashley, William L.
- Abstract
A study of adaptation to work as both a process and an outcome was conducted. The study was conducted by personal interview that probed adaptation with respect to work's organizational, performance, interpersonal, responsibility, and affective aspects; and by questionnaire using the same aspects. The population studied consisted of persons without a college degree, aged seventeen to thirty, and recently employed at a new job. About one-third were at their first full time job, and two-thirds had received vocational training. Data were analyzed by both descriptive and rigorous methods. The results of the study suggest that, for those who adapt successfully, a hierarchy or sequence of adjustments may be involved which may be explained in terms of the five aspects of work selected as the basis of analysis. The worker initially concentrates on job performance skills, then begins to adapt to co-workers, adapts to the organization, and creates interpersonal relationships with peers. The study's findings point to the importance of employers defining their expectations of new employees with respect to their performance, role in the organization, sources of information, and relations to supervision; the findings also point to the importance of preparing students to have realistic expectations of the workplace. Recommendations include replication of the study using validated adaptation measurement instruments and subjects more representative of the general population. (KC)

- Abstract
This publication reports the proceedings of a national symposium that examined from several perspectives the application of occupational adaptability and transferable skills in preparing individuals for tomorrow's careers. Five presentations made up the symposium. Jerry Short spoke on New and Changing Occupations: Jobs and Skills for Tomorrow and offered strategies for teaching adaptability that could assist individuals in becoming adaptable. Speaking on An Employer's Concern with Occupational Adaptability, Richard Peterson stated that both employers and workers must become aware of the transferability of skills as opposed to job specificity in successfully preparing themselves and others for a lifetime of work. Paul Barton's presentation on The Early Youth Employment Experience examined labor market data to show a relationship between education and work. Application of the concepts of transferable skills and occupational adaptability were examined and questioned. Judy Springer gave a status report on training in Business and Industry. In his presentation on Occupational Adaptability and Transferable Skills: Synthesis and Reaction, George Copa reviewed major issues discussed by the other symposium presenters. (LRA)

42. Identifying Transferable Skills: A Task Classification Approach.

Ohio State Univ., Columbus. National Center for Research in Vocational Education., Ashley, William L., and Ammerman, Harry L.
- Abstract
The feasibility of classifying occupational tasks as a basis for understanding better the occupational transferability of job skills was examined. To show general skill relationships among occupations, 5 classification schemes were applied to 50 selected task statements for each of 12 occupations. Ratings by five reasonably knowledgeable people were obtained for the tasks of each occupation. A comparison of the task ratings was conducted to determine the skill components or aspects of tasks that would appear to be similar and could contribute to transfer capability among occupations. Additional exploration was attempted by obtaining overall job ratings, using each classification scheme, for a subsample of four of the occupations. This permitted an examination of the comparability of task-composition versus whole-job bases for identifying the skill components of an occupation. It was concluded that tasks can be individually classified, that at least some classification schemes produce reasonable rater agreement for a wide assortment of types of tasks, and that such classifications can identify different task characteristics. However, there is cause for hesitancy in suggesting further study in more depth and sophistication, due to the conceptually complex and tedious chore for persons asked to rate occupational tasks. Suggestions are made for future studies. Questionnaires (on human attributes, psychological processes, content domains, action processes, and objects of action) are appended along with summary data.

43. Teaching for Transfer: A Perspective. Information Series No. 141.

Ohio State Univ., Columbus. National Center for Research in Vocational Education., Selz, Nina, and Ashley, William L.
- Abstract
Both the process and the antecedents of transfer (transfer of skill or knowledge from prior experiences to new ones) are considered by the authors, who suggest ways that teaching for transfer can be implemented. Three questions relating to transfer are considered: Is the capacity or ability to transfer attended to and developed in education and training programs? Can an individual's ability to transfer be developed and/or strengthened through planned learning experiences? and How do you teach for transfer? In an informal survey of forty teachers, the authors discovered that with the exception of adult education, teachers do not teach for transfer, but rather teach knowledge and skills which they assume the student will be able to transfer. The authors argue that while the aforementioned is important, an essential purpose of education should be to teach for the maximum positive transfer of knowledge and skill information. They indicate that the ability to transfer such learning can be taught, but many educators seem to take the learning process for granted, assuming that the ability to apply previous learnings follows from in-class mastery. Providing practice beyond classroom mastery to application in varying contexts under differing conditions is stressed. (Sixteen practical suggestions for teaching for transfer, presented under awareness, sequencing, practice, and reinforcement are included.) (MEK)

Ohio State Univ., Columbus. National Center for Research in Vocational Education., Ashley, William L., and Kurth, Paula K.
- Abstract
This review presents a summary of the research on displaced worker programs and implications and recommendations for practice that the research supports. Chapter I is an overview of the displaced worker problem. It considers the extent of worker displacement and job loss and summarizes future projections. Chapter II discusses existing programs for displaced workers. These federal programs are described: Job Training Partnership Act programs (including program elements, participation factors, and barriers to program implementation), Trade Adjustment Assistance, and the Employment Service. A section on nonfederal programs focuses on private sector programs, state programs, and community college and vocational-technical school projects. Chapter III offers recommendations as guidelines for actions that educational leaders and program designers can use to strengthen the capacity of educational institutions to serve the needs of adults in job and career transitions. It recommends that (1) educational institutions link with other community agencies; (2) the linkages should include information-sharing mechanisms to facilitate advance notice and early intervention; (3) private industry councils, vocational schools, and colleges should aggressively develop and market displaced worker, retraining, career advancement, and job search programs; and (4) educational institutions should focus on services that they can best provide.

Ohio State Univ., Columbus. National Center for Research in Vocational Education. and Ashley, William L.
- Abstract
A basic position of industry is that it picks up where schools leave off. Training policy within industry is diverse in theory and practice. Companies vary in their approach to training, ranging from highly informal to highly formal. The many new trends in industrial training may be analyzed in four dimensions: in-house education programs, educational and training facilities, degree-granting institutions, and satellite universities. Most employers responding to a National Center for Research in Vocational Education survey on trends in industrial training state that technology dictates the initial outline of training needs. Training was found to occur both in-house and at the customer's site. Popular training trends included teletraining, computer-based training, creative uses of videodiscs, touch-screen data entry techniques, increased use of adult education techniques, interpersonal and similar skills training, and small-group training. Vocational training programs for skilled workers must keep pace with the constantly changing needs of industry, help students develop preemployment qualifications, avoid adopting or clinging to provincial attitudes and practices that are inconsistent with the realities affecting firms hiring vocational graduates, and prepare workers to assume more responsibility for updating themselves as new technological developments and practices affect their occupations.

- Abstract
An investigation of quality indicators in high-technology programs in two-year postsecondary institutions explored three questions: the nature of high technology and its implications for educational practice; the essential components and features of a quality program; and the level of implementation of quality characteristics in exemplary programs. Conducted through surveys of over 140 educators and high technology industry representatives, the study resulted in identifying 46 practices that were judged as indicators of a quality program. A review of program practices reflected a high level of consistency between the perceived importance of these indicators and the extent of their implementation. Across 84 high-technology programs in 13 different technology areas in 25 different states, the following were judged as essential or very important elements: (1) technologically up-to-date faculty, equipment, and curriculum; (2) program content and practices relevant to work needs; (3) close attention to the needs of students; and (4) close cooperation between an educational institution and the related business/industry. (A profile of successful high-technology programs is offered in the report.) As a result of the project, a self-assessment process and supportive materials were developed and made available to the high-technology educational community. In addition to the study instruments, appendixes include a program listing, a table of indicator ratings by program area, and a program self-assessment form for participating faculty. (KC)
