Size Assessment of the Gray Reef Shark Carcharhinus amblyrhynchos Inferred from Teeth Marks on Human Wounds

An accurate assessment of the biting shark size is paramount for better understanding the agonistic behavior of a species toward humans. The gray reef shark is involved in many accidental bites. Based on the capture of 35 gray sharks, we calculated the algorithm that allows the assessment of the shark size, through the interdental distance (IDD) inferred from teeth marks on human wounds. Our results show a negative allometric relationship and that IDD calculated from imprints perpetrated by the upper jaw are globally similar with those from the lower jaw, in spite of heterodonty. We applied our findings to two cases of accidental bites by this species. Both of the victims had declared that the shark length was “at least 2 m”. Based on our algorithm, the assessment of the shark TL was approx. 180 and 160 cm, respectively, which correspond to an overestimation of ≥20% by the victims.     

In Search of the Holy Grail in Public Service: A Study on the Mediating Effect of Public Service Motivation on Organizational Politics and Outcomes

ABSTRACT

There appears to be a research gap in terms of examining whether PSM will hold fast even in the midst of a politically charged work environment. This article investigates how highly motivated government employees would react to the potentially adverse effects of political perception (POP) on organizational commitment, job satisfaction and workplace stress. The findings indicated that PSM exists among the respondent municipal social workers in the Philippines and that this motivation directly translates to positive outcomes. However, PSM did not have the expected mediating effect which is a departure from the commonly held view about its buffering power and mitigating role.

Effects of Public Service Motivation on Turnover and Job Satisfaction in the U.S. Teacher Labor Market

A substantial body of research has addressed the importance of the match between the person and the organization, or jobs for individuals and organizational outcomes across diverse fields. Despite growing attention to the role of the person–environment (P–E) fit, there are few studies incorporating the characteristics of jobs in the relationship between public service motivation (PSM) and job satisfaction. Drawing on the growing literature concerning PSM and teacher recruitment and retention, this study investigates whether altruistic work values, such as a strong altruistic desire and a preference for correcting social inequity, affect job satisfaction and teacher turnover.     

Work Engagement in the Public Service Context: The Dual Perceptions of Job Characteristics

Interest in work engagement research has increased significantly due to its positive influence on both employee and organizational performance. Studies show how engagement is explained through job characteristics in the Job Demands-Resource model, yet a more nuanced approach has been proposed. In this qualitative study, home caregivers’ perceptions of job characteristics are investigated. Semi-structured interviews and observations reveal three main themes: Optimization, helping others, and emotional work. These show a dual perception of job characteristics consequently influencing the experienced engagement. Using Public Service Motivation literature, these dual perceptions are discussed.     

Public Service Motivation and Job Sector Choice: Evidence from a Developing Country

This article explores the determinants of actual job sector decisions of highly skilled professionals across four different sectors in a developing country, with a particular interest in the relationship with public service motivation (PSM). Unlike most previous cross-sectional studies, it uses a pooled time series of individual antecedents and job characteristics, both before and after the individuals leave the job market to pursue graduate education abroad. The results indicate that there are key differences in terms of the determinants of job sector choices across the four sectors, and that PSM appears to have a differential role on the attraction of individuals to each of those sectors.

Testing an International Measure of Public Service Motivation: Is There Really a Bright or Dark Side?

‘Public service motivation’ (PSM) is usually reported as a bright force although recent debate alludes to a dark side. Variables representing each side are, respectively, job satisfaction and burnout. This study tests for both the bright and potential dark direct effects of PSM and responds to calls to further validate the international PSM instrument developed by Kim et al. ( 2013 ). Using a sample of 455 local council workers in Australia, analysis confirmed that while the measure was robust and generalizable in its structure, none of the dimensions of PSM were found to influence either job satisfaction or burnout. Plausible explanations include contextual factors, nomological concerns with the measurement instrument, and the notion that PSM has a non‐significant influence on either. The implications of these findings are discussed and future research proposed.     

The Personality Assessment Inventory (PAI): Treatment Scales and Interpersonal Characteristics in a Sample of Men Charged with or Convicted of a Sexual Offense*

An individual's interpersonal features are pertinent to treatment within clinical populations. The Personality Assessment Inventory (PAI) contains two scales that assess the interpersonal features of warmth (WRM) and dominance (DOM), as well as two additional measures to assess to treatment prediction, process, and rejection (RXR; TPI). The current study examined associations between these PAI scales in a sample of 92 men who underwent comprehensive evaluations of sexual behavior after being charged with or convicted of a sexual offense. Analyses indicated that RXR was positively associated with WRM and DOM, TPI was negatively associated with WRM, and the two interpersonal scales of WRM and DOM were positively correlated with each other. A significant inverse relationship was found between the two treatment scales RXR and TPI indicating that motivation for treatment may have a limited relationship with the treatment process. WRM significantly predicted scores on the TPI, and both WRM and DOM predicted individual scores on RXR. Higher scores on positive impression management (PIM) were predictive of lower TPI and higher RXR, as individuals with higher stakes cases may score higher on PIM and underreport obstacles within treatment or be unwilling to accept the need for treatment. Overall, findings suggest that interpersonal characteristics identified by the PAI scales may be advantageous in approaching treatment within this population.     

Reluctant policy innovation through profit concession and informality tolerance: A strategic relational view of policy entrepreneurship in China's urban redevelopment

This paper engages with the theoretical perspective of policy entrepreneurship to examine the pattern and process of policy change in the context of China's urban redevelopment. Drawing upon a strategic-relational reinterpretation of policy entrepreneurship, this paper identifies a distinctive form of reluctant policy innovation in the “three old renewals” scheme initiated in Guangzhou where profit concession and informality tolerance were practiced to create a small window of opportunity for the project of urban redevelopment to break ground. The motivation of policy entrepreneurship in the successful urban renewal projects in Guangzhou was heavily contingent upon the geographically important location of the project site and the historically incidence of hosting the 2010 Asian Games, which forced municipal government to become entrepreneurial and innovative in decision making and income redistribution in order to get things done as quickly as possible. The distinct fashion of policy innovation identified in the case of Guangzhou points to the polymorphous and dynamic nature of policy entrepreneurship and advocates a relational treatment of the strategies and motives of policy entrepreneurs embedded in concrete geographical and historical context.
