Careers in aging: how job-seekers search for and how employers advertise positions in aging-related markets     

Tina M. Kruger  Leanne J. Clark-Shirley  Marc Aaron Guest 《Educational gerontology》2013,39(7):483-494

Given its rapidly-aging population, the U.S. needs a workforce that is informed about and capable of meeting the diverse needs of older adults. Students pursing gerontology education may feel unsure of career opportunities as they enter a job market with traditionally clearly-defined disciplinary backgrounds. The goal of this study was to explore how people currently employed in an aging-related job searched for positions, and how this compared to phrasing used by employers to advertise job openings across several aging-related fields. A web-based survey was administered to employees in aging-related positions, and a search of four job-seeking websites to collect and analyze aging-related job postings was conducted. Most (63%) currently working in the field of aging reported finding their jobs through referral from a friend/colleague or through job search sites or job boards. Out of 493 relevant job postings identified, only 175 of the postings (35%), preferred or required applicants to have some type of aging-related knowledge, skills, training, or prior experience. There may be consequences to not specifically recruiting applicants with aging-related backgrounds: job seekers with qualifications in aging may look for other positions that expressly call for their specialized skills or knowledge, and quality of services and care may be different when provided by persons without such training.  相似文献   

核心稳定性在人体运动中的作用   总被引：1，自引：0，他引：1  

周瑾 《北京体育大学学报》2008,31(12)

在体育运动中,核心的主要作用是稳定身体、是肌肉发力的基础,这一点日益得到公认。从跑步到投掷等各项体育运动中,稳定的核心是有效发挥人体生物力学功能的关键因素,从而使肌肉发力最大化并最大限度减小关节负荷。我们将核心肌群的功能理解为中枢神经系统预设的程序,这个程序整合局部的、单关节和多个关节上的肌群活动,在保持整体稳定的同时完成体育动作。近端的稳定性是远端灵活性的基础,在这个基础上可以建立从近端向远端的发力模式,并且可以通过肌群的协同作用力在完成远端动作的同时保护远端关节。评估动态核心能力是一项重要任务,其中包括对躯干特定功能和三维运动能力的评估。运动康复训练计划应该包括核心能力的重建,并且应该将核心视为远端肢体运动的基础。  相似文献

A locus of control and social distance comparison of Canadian and West Indian-born students     

Aaron Wolfgang  David S. Weiss 《Int J Intercult Relat》1980,4(3-4)

Three hundred and seventy-nine participants were tested in the West Indies and in Canada, with the Rotter Locus of Control Scale and the Wolfgang Interpersonal Distance Test. The results indicated that West Indian adolescent students were more internally controlled than their Canadian counterparts. Also, overall, West Indian students showed more approach behavior toward significant interpersonal figures than Canadian students. In addition, no correlation was apparent between locus of control and social distance, suggesting that they are separate constructs. Implications of the findings for social adjustment of West Indian immigrants in Canada are discussed.  相似文献   

The formation and evolution of international research alliances in emergent technologies: Research issues     

Sally Davenport  Aaron Miller 《The Journal of High Technology Management Research》2000,11(2):473

Access to knowledge is increasingly the driver underpinning the globalization of research. In emerging industries, such access is often managed through alliance structures between small entrepreneurial organizations. The literature on international alliances, however, is dominated by studies of “Triad” nation partners (United States, Europe and Japan) which are often larger firms, collaborating for market access motives and usually with established technologies. In addition, prior research has concentrated on particular aspects, such as motives for, and initial circumstances of, alliance formation. Analyses of the dynamic aspects in the relationship between alliance partners are more scarce. This article describes a study of an international research alliance in which the technology is in the superconductivity industry (which itself is not conforming to traditional notions of an emergent technology), one partner is from a non-Triad nation and the primary motive for formation was access to knowledge. We argue that this study has revealed gaps in current alliance research and hypothesize how some more socially based and process-related considerations could enhance the debate on knowledge-seeking alliances.  相似文献

Politically correct hiring Will Destroy higher education     

Aaron Wildavsky 《Academic Questions》1994,7(1):77-79

Aaron Wildavsky, a founder and president of the California Association of Scholars, died on September 4, at the much too early age of 63. Professor Wildavsky's life exemplified a total commitment to the university, and his achievements were prodigious. He authored or edited, alone or with colleagues, some three dozen books, and he wrote hundreds of articles. In the thirty years he spent at Berkeley, he was at various times chairman of the Department of Political Science and founding Dean of the Graduate School of Public Policy. He also found time to serve as president of the American Political Science Association and the Policy Studies Association, and to be active in myriad other organizations. When Yale, where he had earned his doctorate in 1959, earlier this year made him an honorary Doctor of Social Science, it stated, “You have improved every institution with which you have been associated.” Aaron Wildavsky was profoundly concerned about the future of the university, the institution that he loved so much and served so well. At the Fourth National Conference of the NAS, held in San Francisco this past April, he expressed his fears about the effect of politically correct faculty hiring practices on the long-range future of education. Academic Questions here reproduces his remarks in the hope—one that, in fact, he shared—that for once his predictions will be proved wrong.  相似文献   

Neural information retrieval: at the end of the early years

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.  相似文献   

Scanning technology selection impacts acceptability and usefulness of image-rich content     

Kristine M. Alpi  James C. Brown  Jr.  Jennifer A. Neel  Carol B. Grindem  Keith E. Linder  James B. Harper 《Journal of the Medical Library Association》2016,104(1):15-23

Objective

Clinical and research usefulness of articles can depend on image quality. This study addressed whether scans of figures in black and white (B&W), grayscale, or color, or portable document format (PDF) to tagged image file format (TIFF) conversions as provided by interlibrary loan or document delivery were viewed as acceptable or useful by radiologists or pathologists.

Methods

Residency coordinators selected eighteen figures from studies from radiology, clinical pathology, and anatomic pathology journals. With original PDF controls, each figure was prepared in three or four experimental conditions: PDF conversion to TIFF, and scans from print in B&W, grayscale, and color. Twelve independent observers indicated whether they could identify the features and whether the image quality was acceptable. They also ranked all the experimental conditions of each figure in terms of usefulness.

Results

Of 982 assessments of 87 anatomic pathology, 83 clinical pathology, and 77 radiology images, 471 (48%) were unidentifiable. Unidentifiability of originals (4%) and conversions (10%) was low. For scans, unidentifiability ranged from 53% for color, to 74% for grayscale, to 97% for B&W. Of 987 responses about acceptability (n=405), 41% were said to be unacceptable, 97% of B&W, 66% of grayscale, 41% of color, and 1% of conversions. Hypothesized order (original, conversion, color, grayscale, B&W) matched 67% of rankings (n=215).

Conclusions

PDF to TIFF conversion provided acceptable content. Color images are rarely useful in grayscale (12%) or B&W (less than 1%). Acceptability of grayscale scans of noncolor originals was 52%. Digital originals are needed for most images. Print images in color or grayscale should be scanned using those modalities.  相似文献
