Choosing the Right Password Manager

Abstract

This segment of the Sharpest Tool in the Shed column explores three password manager options to consider incorporating into your library. Many libraries and businesses still rely on an Excel spreadsheet to house the myriad log-ins and passwords that staff need to do their daily work. Choosing the right password manager can save staff time and enhance security. This segment draws on research and trial experiences of three popular password managers: 1Password, LastPass, and KeePass.     

The Poisson Birnbaum–Saunders model with long-term survivors

In this paper, we propose a cure rate survival model by assuming that the number of competing causes of the event of interest follows the Poisson distribution and the time to event has the Birnbaum–Saunders (BS) distribution. We define the Poisson BS distribution and provide two useful representations for its density function which facilitate to obtain some mathematical properties. Two closed-form expressions for the moments of the new distribution are given. We estimate the parameters of the model with cure rate using maximum likelihood. For different parameter settings, sample sizes and censoring percentages, several simulations are performed. We derive the appropriate matrices for assessing local influence on the parameter estimates under different perturbation schemes and present some ways to perform a global influence study. We analyse a real data set from the medical area.     

Ethical leadership and group in-role performance: The mediating roles of group conscientiousness and group voice

In this paper, we propose that ethical leadership will lead to higher group in-role performance. Building from and integrating several different research streams, we argue that two key mechanisms for this effect are group conscientiousness (an emergent state) and group voice (a group process). We collected survey data at three points in time from 80 groups of nurses and the groups' leaders. The results provide support for all of our hypotheses. There was a positive relationship between employee ratings of ethical leadership (Time 1) and leader ratings of group in-role performance (Time 3). Group conscientiousness and group voice (Time 2) both partially mediated this relationship. These results contribute to our understanding of leadership and group effectiveness not only by showing that ethical leadership has a positive influence on group in-role performance, but also by identifying specific norms and group-level behaviors that help to account for this relationship.     

Understanding Policy Reform in Colorado's Domestic Violence Offender Treatment Standards

This study examines the perceived conditions leading to Colorado adopting revised Standards for treating domestic violence offenders from the perspective of Kingdon's multiple streams theory. A within‐case analysis of ten semi‐structured interviews explores the Domestic Violence Offender Management Board in Colorado's process for revising Colorado's 2001 Treatment Standards. Findings suggest a benign political stream, supported by technically feasible and value‐accepted policy ideas, feedback and indicators of the problem, promoted a favourable setting for change. At least two policy entrepreneurs championed the decision‐making process. Agenda setting and policy formulation depended on three elements: feedback from existing programmes, indicators of continued difficulty in effectively treating offenders, and the existence of a suitable policy alternative. This study contributes a rare application of multiple streams theory to a criminal justice context in a sub‐national government. Future research should explore whether the presence of a benign political stream influences the development and revision of domestic violence policy in other policy environments.     

Elderly chinese and their family caregivers' perceptions of good care: a qualitative study in shandong, china

This study aims to understand what older Chinese people with chronic illness and their family caregivers perceive to be good care, and to compare perspectives of those living in rural and urban areas. We conducted semistructured interviews with 24 care recipients and 23 caregivers in Shandong, China. Two major themes were identified: (a) filial piety as the standard, and (b) modifying cultural ideals to meet reality. There was overall consistency in perceptions of study participants. Variations between rural and urban elders' perceptions appear to reflect differences in socioeconomic development and institutional structures.     

Of Practicalities and Perspective: What Is Fair in Group Decision Making?

Establishing fair procedures to regulate intragroup disagreements should engender cooperation while inhibiting conflict . Yet what is a "fair" procedure might vary for members of different factions . To understand perceptions of fairness in group decision making , the present research developed and utilized the Fair Group Procedures Scale (FGPS). Exploratory and confirmatory factor analyses revealed a four-factor structure along two dimensions: the means of distributing decision-making power (proportionality to equality) and the normative value of the approach (desirable to undesirable) . Data suggest that deeming a particular decision-making procedure "fair" is predicted by one's majority/minority position within a group . Furthermore , experimental data suggest that social change (i . e ., reversals of majority/minority positions) reduces the discrepancies between factions . Results support the socially constructed nature of fairness and its potential role in intragroup conflict .     

Inferences from logistic regression models in the presence of small samples,rare events,nonlinearity, and multicollinearity with observational data

The logistic regression model has been widely used in the social and natural sciences and results from studies using this model can have significant policy impacts. Thus, confidence in the reliability of inferences drawn from these models is essential. The robustness of such inferences is dependent on sample size. The purpose of this article is to examine the impact of alternative data sets on the mean estimated bias and efficiency of parameter estimation and inference for the logistic regression model with observational data. A number of simulations are conducted examining the impact of sample size, nonlinear predictors, and multicollinearity on substantive inferences (e.g. odds ratios, marginal effects) when using logistic regression models. Findings suggest that small sample size can negatively affect the quality of parameter estimates and inferences in the presence of rare events, multicollinearity, and nonlinear predictor functions, but marginal effects estimates are relatively more robust to sample size.     

An empirical approach to determine a threshold for assessing overdispersion in Poisson and negative binomial models for count data

Overdispersion is a problem encountered in the analysis of count data that can lead to invalid inference if unaddressed. Decision about whether data are overdispersed is often reached by checking whether the ratio of the Pearson chi-square statistic to its degrees of freedom is greater than one; however, there is currently no fixed threshold for declaring the need for statistical intervention. We consider simulated cross-sectional and longitudinal datasets containing varying magnitudes of overdispersion caused by outliers or zero inflation, as well as real datasets, to determine an appropriate threshold value of this statistic which indicates when overdispersion should be addressed.     

Improving Graduation Rates in Drug Court Through Employment and Schooling Opportunities and Medication-Assisted Treatment (MAT)

ABSTRACT

Drug courts have been a key part of the criminal justice system since 1989, and this study contributes to the existing body of research by identifying which participants (n = 248) were most likely to graduate from a drug court in Indiana (United States). Three variables emerged as significant predictors of graduation. First, participants who were employed or were students at the time of admission were nearly 2.5 times more likely to graduate than participants who were not. Second, participants who were using opiates as their primary drug of choice were over 80% less likely to graduate than participants who were using non-opiates as their primary drug of choice. Third, participants who had violations in the first 30 days of the program were nearly 50% less likely to graduate than participants who did not violate in the first 30 days. Offering medication-assisted treatment (MAT), such as methadone, Suboxone, or Vivitrol, to participants who have an opiate use disorder may improve graduation rates for this population. Additionally, graduation rates may also improve by offering more resources to assist participants in gaining and maintaining employment or schooling, and this seems to be especially important within the first month of the program.
