The reference section of every library remains an important arm of such library. It contains materials needed for teaching, learning, community development and research. However, studies have shown that most of these materials are rarely consulted by library users, hence, the rationale of the present study which investigated the extent to which reference materials are accessed and utilized by the undergraduates of library and information science (LIS), Taraba State University (TSU), Jalingo. Six research objectives with corresponding research questions were considered and answered. The descriptive survey method was adopted using a total population of 133 final year undergraduates of LIS, TSU, Jalingo. Furthermore, the complete census technique was employed to study the entire population. A fifty-eight (58) items questionnaire was used for data collection. 133 copies were distributed, but 127 (95.5%) copies were returned and found suitable for data analysis. The data analysis was done using descriptive statistics of mean scores and frequency counts. Findings revealed a high extent of accessibility of a good number of reference materials. Few of these materials were reported to be utilized to a high extent leading to a relationship between the extent of accessibility and utilization. However, numerous challenges were identified to be facing the accessibility and utilization of reference materials by the undergraduates. The study concludes that the extent of accessibility determines the extent of utilization which all proved to be high in the library studied. It was, however, among other things, recommended that the management of university libraries should intensify efforts to improve the number and quality of reference materials provided and make them accessible to their users.

In Data Envelopment Analysis (DEA) the situation of inputs vs. outputs is positioned as cause and effect. Effects include desirable (ordinary) outputs and undesirable outputs, e.g. pollutants. This situation is well studied and many applications have been published. In this paper, we introduce a new type of inputs, called Good (Desirable) Inputs. As explained in Introduction, we find several examples of such inputs, e.g. Electric car, Women in office and Test takers of vaccine. We handle this by means of SBM (Slacks-based Measure). Usually, efficiency values of DEA models are in the range (0, 1], while in this model a negative efficiency value may be assigned to inefficient DMUs (decision making units). This is caused by shortages of Good Input values. As an example, we refer to “Women’s Rights Movements” in a country where women’s right is not fully guaranteed. Suppose local governments where men and women are serving as officers. They are inputs to office, while Women are Desirable input and Men are Ordinary input. As outputs, we assume Service as Ordinary output and Claim as Undesirable output. Several extensions of this model are introduced. (a) Variable returns to scale, (b) Weight restrictions, (c) Super-efficiency issue and (d) SBM_Max model.

The subsistence and development of every Institution and organization, to a large extent, depends on the employees’ output. Therefore, it is authoritative for employers to make room for the satisfaction of employees in order to retain their due services. The purpose of the study was to examine the effects of intrinsic and extrinsic motivation on staff retention at Public Universities in Ghana (PUG). Primary data was collected from a total number of eighty (80) respondents comprising junior staff, senior staff, and senior members from PUG using structured questionnaires and interview guide to establish both extrinsic and intrinsic motivational factors that encourage staff retention on their job. Consequently, both quantitative and qualitative data were used. The influence of intrinsic and extrinsic motivation in PUG was characterized and analyzed to generate frequencies and percentages with the help of Microsoft Excel. The research findings showed that salary/wages, promotion, leave and health benefits, job security, accommodation, and transportation were the topmost variables that encourage employees extrinsically to remain on their jobs. There are lots of intrinsic and extrinsic motivational factors in the Public Universities of Ghana. However, the staff does not have intentions to see the downfall of their employer. In order to improve staff motivation at the Public Universities in Ghana, the finding factors have been indicated in the writeup.

We consider a principal (e.g., a ridesharing platform such as Uber or Lyft) who receives two types of jobs (e.g., passengers requesting solo or shared rides) according to a Poisson process. The principal first decides which jobs to admit and then assigns an agent (e.g., driver) to perform them. The agent who is assigned the job has preference between the two types of jobs. The agent can independently decide whether to accept or reject a job which is assigned to them. The principal and the agent receive different rewards from each job thus resulting in incentives misalignment. The research questions are: (1) which job(s) should the principal admit? (2) How much should the principal pay the agent? To answer these questions, we model the agent as an M / M / 1 loss system. Using a Markov decision process and dynamic programming, we find the optimal wage the principal should pay the agent and a threshold admission policy (also known as trunk-reservation or switching-curve policy). Prior literature did not consider two players (agent and principal) with misaligned objectives and each making dynamic decisions. We contribute to the literature by adding another layer of decision making and by introducing server (agent) independence wherein the servers have preferences regarding the type of job they wish to perform.
我们考虑一个委托人(例如，像Uber或Lyft这样的拼车平台)，他根据泊松过程接受两种类型的工作(例如，要求单独或共享乘车的乘客)。主体首先决定接受哪些作业，然后分配一个代理(例如，司机)来执行这些作业。被分配任务的代理在这两种类型的任务之间有偏好。代理可以独立决定是否接受或拒绝分配给它们的任务。委托人和代理人从每项工作中获得不同的报酬，从而导致激励失调。研究问题是:(1)校长应该录取哪些工作?(2)委托人应向代理人支付多少费用?为了回答这些问题，我们将代理建模为M / M / 1损失系统。利用马尔可夫决策过程和动态规划，我们找到了委托人应该支付给代理人的最优工资和阈值准入策略(也称为干线保留或切换曲线策略)。先前的文献没有考虑两个目标不一致的参与者(代理人和委托人)，每个人都做出动态决策。我们通过添加另一层决策和引入服务器(代理)独立性(其中服务器对它们希望执行的作业类型具有偏好)来为文献做出贡献。
