OBJECTIVE: The present study describes factors related to fatal abuse in three age groups in the United States Air Force (USAF). METHOD: Records from 32 substantiated cases of fatal child abuse in the USAF were independently reviewed for 60 predefined factors. RESULTS: Males were over-represented in young child victims (between 1 year and 4 years of age) and child victims (between 4 years and 15 years of age) but not in infant victims (between 24 hours and 1 year of age). African-American infant victims and perpetrators were over-represented. Younger victims were more likely to have been previously physically abused by the perpetrator. Perpetrators were predominantly male and the biological fathers of the victims. Infant and young child perpetrators reported childhood abuse histories, while child perpetrators reported the highest frequency of mental health contact. Victims' families reported significant life stressors. Families of young child victims were more likely divorced, separated, or single. Incidents with infants and young children tended to occur without witnesses; incidents with child victims tended to have the victim's sibling(s) and/or mother present. Fatal incidents were more frequent on the weekend, in the home, and initiated by some family disturbance. CONCLUSIONS: Differences among groups in factors related to infant and child homicide across age groups may assist in the development of more tailored abuse prevention efforts and may also guide future investigations.  相似文献

Public anonymity and the connected world     

Tony Doyle  Judy Veranas 《Ethics and Information Technology》2014,16(3):207-218

We defend public anonymity in the light of the threat posed by digital technology. Once people could reasonably assume that they were fairly anonymous when they left the house. They neither drove nor walked around with GPS devices; they paid their highway tolls in cash; they seldom bought on credit; and no cameras marked their strolls in the park or their walks down the street. Times have changed. We begin with a brief discussion of the concept of anonymity. We then argue that public anonymity helps promote privacy in public. Next, we argue that public anonymity is worth protecting insofar as it promotes autonomy. After that we attempt to show how digital technology threatens public anonymity in the context of CCTV and GPS devices. We argue for a significant scaling back of public surveillance. We close with some thoughts on what we take to be the gratuitous costs imposed on those who would attempt to preserve their anonymity in public.  相似文献   

Outside directors on the board and innovative firm performance     

Benjamin Balsmeier  Achim Buchwald  Joel Stiebale 《Research Policy》2014

We investigate how outside directors on supervisory boards influence innovative activities of the firms they advise and monitor. Based on panel data on the largest German companies, the econometric analysis shows a positive influence of external executives on innovative firm performance, measured by patent applications. Differentiating between outside directors from innovative and non-innovative companies reveals that only outside directors from innovative firms increase patenting activities at the firms they advise and monitor. This effect increases with the technological proximity between the appointing firm and the outsider's home firm. Outside directors from non-innovative firms are negatively associated with the appointing firm's innovativeness. The results indicate that external executives with an appropriate professional background can provide valuable specific knowledge and expertise to the board.  相似文献   

The role of the entry-and-stretch phase at the different paces of race in front crawl swimming     

Mathias Samson  Tony Monnet  Anthony Bernard  Patrick Lacouture  Laurent David 《Journal of sports sciences》2015,33(15):1535-1543

The aim of this study was to determine the role played by the entry-and-stretch phase in the coordination of swimming, at the different paces of race. Three national level swimmers (two men and one woman) were recorded, in lateral and bottom views, in three swimming paces: sprint (50 m and 100 m), middle-distance (200 m and 400 m) and long-distance (800 m and 1500 m). Anatomical landmark positions were obtained by manual digitalisation of the videos. Computational fluid dynamics and experimental studies (with a strain gauge balance and particle image velocimetry method) were used to measure and to calculate the external forces applied to the hand and to the forearm and to visualise the flow around the profile. Entry-and-stretch is the phase which varies the most according to the swimming pace. This phase can be decomposed into two sub-phases: one, the extension forward coordinated with the insweep of the opposite arm, and another one, the rotation downward coordinated with the upsweep. Results show that, at the three paces, this phase is not propulsive and could contribute essentially to maintain the horizontal balance of the body.  相似文献   

Instructional leadership in centralised systems: evidence from Greek high-performing secondary schools     

Maria Kaparou  Tony Bush 《School Leadership & Management》2015,35(3):321-345

This paper examines the enactment of instructional leadership (IL) in high-performing secondary schools (HPSS), and the relationship between leadership and learning in raising student outcomes and encouraging teachers’ professional learning in the highly centralised context of Greece. It reports part of a comparative research study focused on whether, and to what extent, IL has been embraced by Greek school leaders. The study is exploratory, using a qualitative multiple case design to examine two HPSS in Athens. The research design involved a qualitative approach using several different methods, including semi-structured interviews with school principals, deputy heads, subject teachers and subject advisers, plus observation of leadership practice and meetings and scrutiny of relevant policy documents. The findings show that IL is conceptualised as an informal collaborative leadership practice, interwoven with the official multi-dimension role of Greek principals and their ‘semi-IL’ role. In the absence of official IL ‘actors’, teachers’ leadership has been expanding.  相似文献   

TESOL professional standards in the “Asian century”: dilemmas facing Australian TESOL teacher education     

Indika Liyanage  Tony Walker  Parlo Singh 《Asia Pacific Journal of Education》2015,35(4):485-497

Australian teacher education programmes that prepare teachers of English to speakers of other languages (TESOL) are confronting the nexus of two facets of globalization: transformations in the Asian region, captured in the notion of the “Asian century”, and shifting conceptions of professionalism in TESOL in non-compulsory education. In booming Asian economies, English language learning is integral to the demand for high-quality education. This has produced increases in TESOL Teacher Education Programme (TTEP) enrolments of both domestic Australian students and international students from Asia. Growth in demand for TTEPs has necessitated that they cater to student diversity, and the intended contexts of practice. This demand has coincided with a concurrent movement towards professional standards for TESOL that, we argue, confronts complexities around quality, accountability, and professional identity and achieving conceptual and contextual coherence. Drawing on discourses of managerialism and performativity, this paper explores tensions between increased student demands for TTEPs, professional standards discourses which are part of the global policy discourses on teacher quality, and the achievement of programmatic conceptual and contextual coherence from the perspective of Australian TTEPs.  相似文献   

The involvement of migrant mothers in their children’s education: cultural capital and transnational class processes     

Taghreed Jamal Al-deen  Joel Windle 《International Studies in Sociology of Education》2015,25(4):278-295

This paper analyses the kinds of capital, practices and investments that are implicated in the participation of migrant mothers in the educational careers of their children, drawing on a Bourdieusian framework. We present findings of a study of Muslim Iraqi mothers with school-aged children in Australia, based on 47 interviews with 25 participants. The study identifies different modes of involvement in children’s education and connects these to mothers’ cultural and social capital. Involvement, and its effectiveness, is analysed through the analytical categories of (i) high capital-high involvement; (ii) low capital-high involvement; and (iii) low capital-minimal direct involvement. The paper contributes to the theorisation of family–school relations in the context of migration, and develops a more nuanced perspective for studying social class positioning and repositioning.  相似文献
