Questions from Newbies—Facilitating Communication and Professional Development: A Case Study

Abstract

For new collection managers, it may be intimidating to ask questions about processes that seem to be common knowledge for their more experienced colleagues. To help with this issue, the Collections & Research Strategy department at North Carolina State University Libraries uses a shared document where new collection managers can log questions as they arise. The questions are shared at regular Collections Interest Group meetings and often generate interesting discussions that librarians both new and experienced can benefit from. This case study will provide an overview of the structure of the document, how it is used, and the types of questions that get asked.     

Modelling columnarity of pyramidal cells in the human cerebral cortex

For modelling the location of pyramidal cells in the human cerebral cortex, we suggest a hierarchical point process in that exhibits anisotropy in the form of cylinders extending along the z-axis. The model consists first of a generalised shot noise Cox process for the xy-coordinates, providing cylindrical clusters, and next of a Markov random field model for the z-coordinates conditioned on the xy-coordinates, providing either repulsion, aggregation or both within specified areas of interaction. Several cases of these hierarchical point processes are fitted to two pyramidal cell data sets, and of these a final model allowing for both repulsion and attraction between the points seem adequate. We discuss how the final model relates to the so-called minicolumn hypothesis in neuroscience.     

Please wait until I am done! Longitudinal effects of work interruptions on employee well-being

ABSTRACT

Work interruptions are contemporary job stressors that occur frequently in the workplace. Theories on work interruptions and the stressor–strain relationship over time suggest that work interruptions should have a lagged negative effect on well-being. However, we argue that continued changes in work interruptions may also be important for employees’ well-being. We investigated the mid- and long-term effects of work interruptions on employee job satisfaction and psychosomatic complaints across two studies (Study 1: N?=?415, four waves over five years; Study 2: N?=?663, five waves over eight months). Using latent growth modelling, we predicted job satisfaction and psychosomatic complaints with respect to the level of, and changes in, interruptions. Controlling for initial well-being, we found that the mean levels (intercepts) of work interruptions had negative effects on later well-being in Study 1, but not in Study 2. However, increases in interruptions over time (slopes) predicted later well-being consistently. An analysis on reversed effects revealed that only the initial level of psychosomatic complaints positively predicted work interruptions. The studies underscore not only the importance of interruptions for well-being over time in general, but also the particular importance of exposure to increases in interruptions.     

THE IMPACT OF SKILL ON UNION MEMBERSHIP:

A worker's occupation and industry position in the economy primarily determine gender differences in union membership. However, the data reveal that these economic structural factors are not alone responsible. A specific strategy for rethinking the problem examines bargaining power; skill has been identified as a central factor in worker power. Feminists maintain that gender mediates manual skill's effect on union membership. Logistic regression techniques that test for gender interaction effects support the feminist perspective. Manual skill produces lower rates of union membership for women than men with comparable skills.

Student Debates in Policy Courses

This article examines the use of student debates to promote substantive knowledge and policy practice skills. The authors present a pedagogical rationale for student debates, describe the incorporation of debates into a child welfare policy course, and report the results of an evaluation. Students demonstrated significantly greater increases in self-reported knowledge of course topics when they participated in debates than when they observed debates or learned through standard forms of instruction. The majority of students reported satisfaction with the debates, reported that participation improved their policy skills and knowledge, and rated the educational value of debates higher than traditional assignments.     

Phase II trial design with growth modulation index as the primary endpoint

Molecularly targeted, genomic‐driven, and immunotherapy‐based clinical trials continue to be advanced for the treatment of relapse or refractory cancer patients, where the growth modulation index (GMI) is often considered a primary endpoint of treatment efficacy. However, there little literature is available that considers the trial design with GMI as the primary endpoint. In this article, we derived a sample size formula for the score test under a log‐linear model of the GMI. Study designs using the derived sample size formula are illustrated under a bivariate exponential model, the Weibull frailty model, and the generalized treatment effect size. The proposed designs provide sound statistical methods for a single‐arm phase II trial with GMI as the primary endpoint.     

Children's and Adolescents' Decisions about Sharing Money with Others

Two hundred and ninety-four participants aged between 7 and 17 years of age were asked to share out money between themselves and another, imaginary group. Individual responses were recorded as well as responses after discussion in a group with two other participants. The distribution task took place in two different experimental conditions that either gave participants a free choice about how much to offer to the other group or involved making a strategic offer to avoid the other group rejecting an offer and losing all the money. From 10 years of age onwards, when allowed to choose freely how much to share, boys made progressively less generous offers than girls whereas girls' offers remained the same with age. However, when inter-group strategic constraints were present, there were few gender differences from 10 years of age. The order in which games were presented was a powerful influence on the offers that participants made.     

Die Zukunft der Coachingforschung

The article presents a brief summary of the current state of research findings regarding both effectiveness (outcome) and factors contributing to the outcome (process) of coaching. The findings are presented along the dimensions outlined in Greif??s (2008) ??structural model of coaching effects?? as well as Kirkpatrick??s (1994) four-level evaluation taxonomy. The current state of research is critically analyzed and challenges for future research are outlined. It is suggested that coaching research needs to draw on both psychotherapy research and training evaluation in order to do justice to the process nature of coaching and its embeddedness in the organizational context. Promising research scenarios, namely the collaboration between academic research groups and professional coaching associations, and selected research approaches are described.
