A comparative study of Twitter utilization in disaster management between public and private organizations

Twitter has become a commonly used platform by both public and private organizations to assist with the dissemination of information related to disaster management. This research makes use of a mixed‐method approach in determining the extent and manner in which Twitter is used to disseminate disaster management information by both public and private organizations. This research found that public organizations are bound by strict regulations resulting in a lower volume and smaller variety of disaster‐related information being disseminated. The nature of an organization and the processes of decision making therein are suggested to influence the ability of an organization to successfully use Twitter as an effective tool for disaster management. Organizations in Thailand currently underutilize Twitter for disaster management, as neither public nor private organizations use Twitter as a multidirectional communication disaster management tool.     

Emotion Dysregulation,Gender, and Intimate Partner Violence Perpetration: An Exploratory Study in College Students

Intimate partner violence (IPV) is a prevalent problem, as it is bidirectional and perpetrated by both men and women. Emotion dysregulation may influence IPV perpetration among men and women. This cross-sectional survey study of 598 college students investigated the associations between two important factors related to IPV perpetration: gender and emotion dysregulation. Findings illustrated an association between emotion dysregulation and IPV perpetration. The bivariate association between physical violence and one facet of emotion dysregulation differed by gender, such that lack of emotional awareness was associated with violence perpetrated by women, but not men; however, this was not supported in multivariate analyses. These preliminary findings suggest that future work should examine how different emotion regulation deficits may increase IPV by gender.     

Binge Drinking,Greek-Life Membership,and First-Year Undergraduates: The “Perfect Storm” for Drugging Victimization

ABSTRACT

Drugging victimization is an understudied phenomenon. This study examines the relationship between the campus party culture and drugging victimization. Campus party culture has been shown to influence risk of other types of victimization, and there is reason to believe it may also influence drugging victimization. Using three behavioral indicators of participation in the campus party culture—binge drinking, Greek life membership, and first-year student status—this study estimates the main effect of each indicator, and their interaction, on undergraduates’ rates of drugging victimization. Estimating a generalized linear model using a large random sample (N = 6,931) from three universities, results show that each party culture variable and their three-way interaction significantly influenced students’ rate of drugging victimization. Sorority members who were first-year students and binge drank at least once in the past month had significantly higher rates of drugging victimization compared to all other groups of students.     

Hegemony,Force Posture,and the Provision of Public Goods: The Once and Future Role of Outside Powers in Securing Persian Gulf Oil

International relations theories emphasize the stabilizing role hegemons play in world politics. But little scholarship has examined the link connecting hegemony to its potentially positive returns in the security realm: force posture. We correct this deficit by developing and testing an argument about the consequences of different hegemonic force postures under varying threat conditions. We present a typology of force posture options and probe their effects through over-time analysis of how major powers have worked to provide one particularly important public good since 1945: access to Persian Gulf oil. Drawing on field work, we also explore the implications of our framework for current and future US force posture in the region. We conclude that hegemonic stability is a very real phenomenon in the Gulf, but it does not require the massive forward deployment of US forces that has characterized the past twenty years of US presence there.     

Characteristics of Bone Injuries Resulting from Knife Wounds Incised with Different Forces

The aim of this research was to experimentally determine the characteristics of incised bone wounds, which are commonly found in defense injuries. A specially constructed pivoting arm device was used to inflict wounds with controlled forces and direction. Five knives were selected to inflict the wounds on porcine forelimbs. Eight incised wounds were made per knife per force. A larger knife and a greater force caused longer and wider bone wounds. Comparisons of individual knives at the two forces produced varying results in the bone wounds. A correlation was seen between the force and the length (r = 0.69), width (r = 0.63), and depth (r = 0.57) of bone wounds. Serrated‐edge and nonserrated knives can be distinguished from the appearance of the wound. The outcomes may be applicable in forensic investigations to ascertain the forces associated with incised wounds and identify the specific knife used.
