Determining Process Death Based on Censored Activity Data

This article addresses the problem of estimating the time of apparent death in a binary stochastic process. We show that, when only censored data are available, a fitted logistic regression model may estimate the time of death incorrectly. We improve this estimation by utilizing discrete-event simulation to produce simulated complete time series data. The proposed methodology may be applied to situations where time of death cannot be formally determined and has to be estimated based on prolonged inactivity. As an illustration, we use observed monthly activity patterns from 300 real Open Source Software development projects sampled from Sourceforge.net.     

Social movement schools: sites for consciousness transformation,training, and prefigurative social development

ABSTRACT

We develop the concept of “social movement school’ (SMS), showing how these organizational spaces are deliberately designed for purposes of educating, mentoring, training, and coordinating individuals as effective, committed movement agents. SMSs can also be important sites of prefigurative design and practice for future societal development consistent with movement goals. We motivate the theoretical significance of SMSs based on five perspectives in social movement scholarship: (1) resource mobilization; (2) cultural approaches to repertoires of contention; (3) cognitive perspective; (4) micro-mobilization; and (5) biographical consequences of participation. We then offer a typology to capture primary purposes, and spatial reach within the broad field of SMSs. Within-movement variation is illustrated by focusing on a variety of SMSs in the U.S. civil rights movement; and the cross-movement breadth of the concept is illustrated by highlighting contemporary SMS forms drawn from three very different movements–labor, radical feminism, and mindfulness meditation movements. In the interest of launching a research agenda on SMSs, we end with several key questions that could serve to guide future research. Important theoretical, empirical, and practical considerations suggest that SMSs deserve the attention of scholars and activists alike.     

Stages of change and engagement in a family intervention

Prochaska and DiClemente's stages of change model facilitate understanding of engagement difficulties in psychosocial intervention processes. We assessed the link between stages of family change and intervention dropout in a sample of 141 families with relational conflicts between parents and adolescent children. Each family member's stage of change was defined according to three criteria: seeing the conflict as a relational problem, assuming part of the responsibility for the dysfunctional relationship, and understanding one's own mental and emotional states and those of the other family members involved in the conflict (mentalization). Our dropout rate for the sample was 41.8% and was higher for immigrant families. We found a strong association between engagement and the contemplation stage of change, particularly the mother's. In family conflict interventions, participation of all the family members is essential so as raise awareness of the relational aspects of the conflict and the shared responsibility for the conflict and its resolution.     

Probabilistic Analysis of Dam Accidents Worldwide: Risk Assessment for Dams of Different Purposes in OECD and Non-OECD Countries with Focus on Time Trend Analysis

This study presents probabilistic analysis of dam accidents worldwide in the period 1911–2016. The accidents are classified by the dam purpose and by the country cluster, where they occurred, distinguishing between the countries of the Organization for Economic Cooperation and Development (OECD) and nonmember countries (non-OECD without China). A Bayesian hierarchical approach is used to model distributions of frequency and severity for accidents. This approach treats accident data as a multilevel system with subsets sharing specific characteristics. To model accident probabilities for a particular dam characteristic, this approach samples data from the entire data set, borrowing the strength across data set and enabling to model distributions even for subsets with scarce data. The modelled frequencies and severities are combined in frequency-consequence curves, showing that accidents for all dam purposes are more frequent in non-OECD (without China) and their maximum consequences are larger than in OECD countries. Multipurpose dams also have higher frequencies and maximum consequences than single-purpose dams. In addition, the developed methodology explicitly models time dependence to identify trends in accident frequencies over the analyzed period. Downward trends are found for almost all dam purposes confirming that technological development and implementation of safety measures are likely to have a positive impact on dam safety. The results of the analysis provide insights for dam risk management and decision-making processes by identifying key risk factors related to country groups and dam purposes as well as changes over time.     

Scholarly Communications Training: Professional Development for the Next Generation of Scholars

Abstract

Many campuses are seeing increased needs for support in scholarly communications areas such as open access, research identity management, scholarship metrics, and related topics. This article discusses a professional development program that addresses scholarly communications needs for online and in-person graduate students and faculty at UNC Greensboro (UNCG), through a collaborative, interdepartmental effort that brings together librarians from the departments of Research, Outreach, and Instruction (ROI) and Technical Services. The authors provide a brief overview of the literature related to scholarly communications needs and training in academic libraries and discuss the UNCG program’s inception, modules, format, assessment, and future directions.

Understanding parental leave experiences: connecting the dots with a multiple-methods approach

ABSTRACT

This research note draws selected findings from a multiple-methods study conducted in partnership with a large public-sector employer in Portland, OR to describe the added value of this approach for research translation. We focus on how our study of a newly implemented paid parental leave policy can translate to actionable steps for two important end-users: employers and policymakers. Using administrative records (N?=?579), a countywide employee survey (N?=?137 leave-takers) and focus groups (N?=?35), we describe how each data source contributes important and unique information about how the policy’s implementation affected diverse employees. We find gender differences in how employees changed leave-taking in response to the policy, and describe the critical but nuanced role that supervisors play. Working with employers and policymakers to develop and implement thoughtful policies will help to ensure equitable distribution of the benefits of paid leave policies.     

Work–Family Conflict Moderates the Relationship Between Childbearing and Subjective Well-Being

Many empirical studies find that parents are not as happy as non-parents or that parenthood exerts a negative effect on subjective well-being (SWB). We add to these findings by arguing that there is a key moderating factor that has been overlooked in previous research, i.e. the level of work–family conflict. We hypothesize that the birth of a child means an increase in the level of work–family tension, which may be substantial for some parents and relatively weak for others. To outline such an approach, we estimate fixed-effects models using panel data from the Household, Income and Labor Dynamics in Australia survey. We find that childbearing negatively affects SWB only when parents, mothers in particular, face a substantial work–family conflict, providing thus support for our hypothesis.     

Extending the Pillars of Social Policy Financing to Aged Care

Against the background of a recent resounding rejection of substantial increases in user contributions for funding long-term residential care in Australia, and especially of measures that could require realization of housing assets, this paper examines the scope for extending to long-term care the "pillars" approach to financing of retirement incomes and health care. The two latter areas are funded through pillars of general revenue, private insurance, social insurance by way of compulsory levies, and direct user contributions, whereas long-term care is financed only by a large pillar of general revenue and a smaller pillar of user contributions which are themselves drawn largely from transfer payments. Examination of the various pillars in each area suggests that there is limited scope for extending private insurance and user contributions in long-term care, but that there are several social policy grounds for incorporating a social insurance pillar. However, while discussion of social insurance options is growing in several quarters, the current political climate offers little prospect for the adoption of such a scheme.
