Hurricane Isaac: A Longitudinal Analysis of Storm Characteristics and Power Outage Risk

In August 2012, Hurricane Isaac, a Category 1 hurricane at landfall, caused extensive power outages in Louisiana. The storm brought high winds, storm surge, and flooding to Louisiana, and power outages were widespread and prolonged. Hourly power outage data for the state of Louisiana were collected during the storm and analyzed. This analysis included correlation of hourly power outage figures by zip code with storm conditions including wind, rainfall, and storm surge using a nonparametric ensemble data mining approach. Results were analyzed to understand how correlation of power outages with storm conditions differed geographically within the state. This analysis provided insight on how rainfall and storm surge, along with wind, contribute to power outages in hurricanes. By conducting a longitudinal study of outages at the zip code level, we were able to gain insight into the causal drivers of power outages during hurricanes. Our analysis showed that the statistical importance of storm characteristic covariates to power outages varies geographically. For Hurricane Isaac, wind speed, precipitation, and previous outages generally had high importance, whereas storm surge had lower importance, even in zip codes that experienced significant surge. The results of this analysis can inform the development of power outage forecasting models, which often focus strictly on wind‐related covariates. Our study of Hurricane Isaac indicates that inclusion of other covariates, particularly precipitation, may improve model accuracy and robustness across a range of storm conditions and geography.     

The Influence of Parental Financial Socialization on Youth’s Financial Behavior: Evidence from Ghana

How youth manage their money may influence their transitions to adulthood. This may be particularly true for youth in sub-Saharan Africa (SSA), where many youth and young adults lack access to economic opportunities. Parental financial socialization is associated with youth financial knowledge, attitudes, and behavior in research studies conducted mostly in the US, yet little is known about the financial lives of youth living in SSA. Propensity score analysis and robust standard errors with multiple regression were used to examine the relationship between parental financial socialization and youth financial behaviors among a sample of 3,623 youth ages 12–19 and a parent or other adult guardian living in eight out of 10 regions of Ghana. Findings indicated that both parent- and youth-perceived parental financial socialization was a strong and consistent predictor of youth financial behaviors, as was receipt of earned income. Practitioners interested in empowering youth through financial education and inclusion programs might consider how to involve parents and other family members in programs and capitalize on opportunities for youth to have some earned income while they learn how to manage money.     

Ergonomic evaluation of a wheelchair transportation securement system

The Americans with Disabilities Act (ADA) specifies guidelines covering the securement system and environment for wheeled mobility device (WhMD) passengers on the public bus system in the United States, referred to as the wheelchair tiedown and occupant restraint system (WTORS). The misuse or disuse of the WTORS system can be a source of injury for WhMD passengers riding the buses. The purpose of this study was to quantify the risks posed to the bus driver while performing the WTORS procedure using traditional ergonomic analysis methods. Four bus drivers completed the WTORS procedure for a representative passenger seated in three different WhMDs: manual wheelchair (MWC), scooter (SCTR), and power wheelchair (PWC). Potential work-related risks were identified using the four most applicable ergonomic assessment tools: PLIBEL, RULA, REBA, and iLMM. Task evaluation results revealed high levels of risk to be present to drivers during the WTORS procedure. The securement station space design and equipment layout were identified as contributing factors forcing drivers to adopt awkward postures while performing the WTORS task. These risk factors are known contributors to injury and the drivers could opt to improperly secure the passengers to avoid that risk.     

Out of the ashes: the new bachelor of midwifery curriculum at Victoria University

In the past decade, midwifery education has changed significantly in Australia. Previously, a nursing qualification (division 1) was required for entry into midwifery programs and on completion, graduands obtained a postgraduate diploma of midwifery. More recently, bachelor of midwifery programs have also been offered in Australia and currently, a considerable percentage of midwives are prepared for practice in this way. In Victoria, the bachelor of midwifery has been available since 2002, and at this time the third group of graduands are poised to enter the field. Implementation of the bachelor of midwifery program has given rise to many concerns about the development and applicability of this course. Concerns include: complexities of registration with a regulatory board set up primarily for nursing registration; concerns about readiness for practice among bachelor of midwifery graduands; escalating requirements within midwifery courses; and difficulties with meeting course requirements. As this course comes of age in Victoria, it is useful to reflect on some of the challenges encountered along the way. Thus, this paper reports on the journey of one university as it approaches the end of a first year of implementing an independent bachelor of midwifery program, following 5 years involvement as a consortium partner. In particular, it addresses concerns and difficulties encountered during early implementation of the program and then outlines strategies used to improve and strengthen the course. The basic premise of the paper is lessons learnt along the way.     

Civic engagement among student veterans

Abstract

Objective: The purpose of this study was to assess participation rates in civic volunteering among service member and veteran students. Participants: Data for the present cross-sectional study were obtained from the American College Health Association’s (ACHA) 2011–2014 National College Health Assessment II (NCHA). Methods: Demographic characteristics of the study sample were explored by calculating frequencies and percentages by military service status. Research questions were explored with either Fisher’s exact test or maximum likelihood multiple logistic regression. Results: Service member and veteran students were more likely to engage in volunteerism than their non-veteran counterparts. Additionally, student veterans and non-veteran students reported that engagement in volunteer efforts both reduces their feelings of depression and increases their use of mental health services. Conclusion: The findings of this research suggest that the promotion of civic engagement and participation in volunteerism for service member and veteran students on college campuses might contribute to successful reintegration outcomes.     

Navigating Housing Instability and Substance Use: Hidden Tensions Facing Youth in Small Town America

Abstract

Recent scholarship indicates that youth homelessness is a significant problem outside urban areas. However, previous studies have not examined how local contexts shape the experiences of youth who are homeless in rural areas and small towns with high rates of poverty and epidemic drug use. To address this gap, this analysis draws from two components of a large national study of homelessness among youth, using data collected in a small non-urban setting in the Northwest including (1) a subset of 41 (out of 215 nationally) in-depth interviews with youth and (2) a subset of 16 surveys (out of 523 nationally) with service providers. We explored availability of services and how youth navigate housing instability and the service landscape in small communities. We discovered that current or prior addictions sometimes posed risks to the safety of youth and compromised their ability to rely on family supports – a support proving critical in the absence of a formal service infrastructure. Our results suggest that youth experiencing housing instability in the context of high rates of drug use and limited formal services must often choose between meeting competing needs: a place to stay versus sobriety. We discuss the implications for policy, practice, and research.     

Quantifying leader lives: What historiometric approaches can tell us

Historically notable leaders, such as John F. Kennedy, Mohandas Ghandi, and Rupert Murdoch, serve as exemplars in our field of study. Across the domains of military, business, government, ideology, and the arts, these outstanding leaders have markedly impacted the institutions, fields, and broader social structures in which they worked and lived. To understand the unique styles, developmental experiences, and performance contributions of such leaders, a historiometric approach is encouraged. We define this methodological strategy as the study of multiple eminent leaders that requires the translation of historical, qualitative information into quantitative indices of individual differences in leaders. Best practices, limitations, and implications for this technique as an advancement of leadership theory are reviewed.
