According to the research literature, services at academic libraries and institutions of higher education do not adequately address the support needed to help autistic students thrive in college. We surveyed academic librarians about library services for autistic students at their libraries to better understand the relevant library services provided for this population. At the institutions surveyed, 37 % (n = 22) of libraries have a person responsible for accessibility issues, and 63 % (n = 37) do not have a person responsible for accessibility. Additionally, we found that 78 % (n = 47) of academic libraries provide services for disabled students and only 22 % do not (n = 13). Most pertinent to our research, 34 % of libraries (n = 20) provide services for autistic students and 66 % (n = 39) do not provide services for autistic students.  相似文献

Academic libraries are facing the need to closely examine the effectiveness of current organizational functions in response to rapid changes in technology and the information environment. The purpose of this study is to explore the functions and issues of the academic library organization in South Korea based on the librarians' perceptions. We conducted a literature review about the changes in the role of academic libraries and organizational functions. In-depth interviews with 19 librarians and a content analysis of those interviews were conducted. As a result, we identified organizational characteristics pertaining to 1) internal functions of the library, such as communication, leadership, motivation, and team system, and 2) external functions, such as collaboration with external administrative departments, and utilization of personal networks. We also discovered mutual relationships among the functions. In particular, leader's support is important to continuously motivate librarians and increase the effectiveness of the team system, resulting in a positive effect on the reputation of the academic library. This study contributes to the academic library literature by comprehensively and empirically exploring functions affecting the services of academic libraries.  相似文献

When leaving initial professional librarian positions to join new organizations, the authors considered several common factors: salaries and benefits, livability of potential cities, and new colleagues. However, thriving early- and mid-career librarians taking the step into different roles must be able to navigate one less commonly discussed aspect of a workplace transition: differing expectations of original research among institutions and according to job classification.When moving from one tenure track position to another, librarians are likely to encounter different formal tenure requirements and support mechanisms at a new institution. Small universities might weigh the successful completion of day-to-day duties more heavily, with less emphasis on research output. Often larger research institutions are the inverse, with a much heavier emphasis on what research is published or presented, and where. Since expectations can be informally relayed and not expressly stated in job postings or during interviews, understanding an employer's idea of what constitutes significant scholarship is often developed over the course of the first year at an organization.This column will discuss the two main characteristics that typically inform expected research output: the type of institution for which the librarian works and the classification of the individual's position. The authors draw on recent experiences assessing different research expectations when changing employers, as well as current research on the topic. Expectations can also change moving from non-research-intensive positions into tenure-track or continuing-status-eligible positions at the same institution, and librarians in these situations often will have to deal with differing expectations around output metrics or impact factors in their research. Successful librarians changing roles will recognize that research expectations are a continuum, and will be able to assess where their current job falls on the library research spectrum. Once readers determine whether their new position requires a low, medium, or high level of scholarship and service, they can then strategize to adapt their existing agenda to meet expectations.Lastly, the column will help early- and mid-career librarians identify and assess the resources and support available to assist them in continuing their research agendas, regardless of positional research and scholarship expectations. Formal mentors, peer researchers in one's professional network, and new colleagues can all help with the stated and informal expectations of research.  相似文献

This paper defines cultural competence and cultural humility in the context of library and information professionals. Though cultural competence has been the standard of late within LIS, cultural humility is an important next step for information professionals to have the ability to work with the changing multiculturally diverse population throughout the world. Through evaluation of work published within the medical and social work fields, cultural humility frameworks are discussed before describing frameworks that are applicable for information professionals. Cultural humility is a lifelong process that requires education and extensive self-reflection and evaluation. Within the paper is a list of actionable questions that professionals can answer throughout their career that look at their perception of self, fellow professionals, and the communities that they serve. Within the appendix is an individual and organizational level assessment that can be completed to assist in reflection on cultural humility by the professional and organization.  相似文献

基于迭代的比特和功率分配机制,提出了一种低复杂度的比特和功率分配算法.与传统的迭代分配算法不同,该算法在每次迭代中只需要比较几个特定的子载波.该方法在保持传统迭代算法性能的前提下极大地减小了迭代分配算法的复杂度.此外,通过选择等功率分配方案作为初始方案加快了算法的收敛速度,进一步降低了算法复杂度.仿真结果表明,提出的改进算法在基本不牺牲系统性能的前提下有效地降低了算法复杂度.  相似文献
