    Microjansky sources at 1.4 GHz

    Get PDF
    We present a deep 1.4 GHz survey made with the Australia Telescope Compact Array (ATCA), having a background RMS of 9 microJy near the image phase centre, up to 25 microJy at the edge of a 50' field of view. Over 770 radio sources brighter than 45 microJy have been catalogued in the field. The differential source counts in the deep field provide tentative support for the growing evidence that the microjansky radio population exhibits significantly higher clustering than found at higher flux density cutoffs. The optical identification rate on CCD images is approximately 50% to R=22.5, and the optical counterparts of the faintest radio sources appear to be mainly single galaxies close to this optical magnitude limit.Comment: 6 pages, 4 figures, accepted by ApJ Letters 4 May 199

    Medication Adherence: To Have is to Hold

    Get PDF
    Nature of the problem: Medication non-adherence is consistently the most frequent cause of mental health decompensation, relapse of mental illness, and hospitalization. The solution to non-adherence remains quite elusive, despite it being relatively easy to identity as the most major obstacle to successful control of mental illness. Method: Eighteen documents published between years 2002-2012 were rated using the AACN’s evidence leveling system. The 18 studies were examined to better understand what is known and not known about the challenge we face in trying to effect recovery and to prevent relapse of mental illness in the United States. Results: Various study designs, diverse interventions and treatment strategies demonstrated limited success in effecting sustained adherence. However, to date, the literature does not show there to be a single, simple, intervention that is effective. The evidence strongly suggests an interdisciplinary approach, using various combinations of interventions is the best strategy, but not a guarantee. A Power Point presentation was used to share the findings of this project with 13 PMHNP students and 2 active, expert PhD, PMHNPs. Nursing implications: Adherence is a complex, multi-determinant, individualized process that is embedded in the core belief of the person. Nursing can use this knowledge to collaboratively work with patients, their families, and other health care team members to devise approaches to facilitate recovery and understanding of the role of medication adherence in recovery maintenance

    The Electrodynamics of Inhomogeneous Rotating Media and the Abraham and Minkowski Tensors II: Applications

    Full text link
    Applications of the covariant theory of drive-forms are considered for a class of perfectly insulating media. The distinction between the notions of "classical photons" in homogeneous bounded and unbounded stationary media and in stationary unbounded magneto-electric media is pointed out in the context of the Abraham, Minkowski and symmetrized Minkowski electromagnetic stress-energy-momentum tensors. Such notions have led to intense debate about the role of these (and other) tensors in describing electromagnetic interactions in moving media. In order to address some of these issues for material subject to the Minkowski constitutive relations, the propagation of harmonic waves through homogeneous and inhomogeneous, isotropic plane-faced slabs at rest is first considered. To motivate the subsequent analysis on accelerating media two classes of electromagnetic modes that solve Maxwell's equations for uniformly rotating homogeneous polarizable media are enumerated. Finally it is shown that, under the influence of an incident monochromatic, circularly polarized, plane electromagnetic wave, the Abraham and symmetrized Minkowski tensors induce different time-averaged torques on a uniformly rotating materially inhomogeneous dielectric cylinder. We suggest that this observation may offer new avenues to explore experimentally the covariant electrodynamics of more general accelerating media.Comment: 29 pages, 4 figures.

    Young Muslim women's experiences of Islam and physical education in Greece and Britain: a comparative study

    Get PDF
    Previous research suggests that Muslim women can experience particular problems when taking physical education (PE) lessons, for example with dress codes, mixed-teaching and exercise during Ramadan; and they can face restrictions in extra-curricular activities for cultural and religious reasons. The area is under-researched and there is little evidence of comparative studies that explore similarities and differences in cross-national experiences, which is the aim of this paper. Two studies conducted in Greece and Britain that explored the views of Muslim women on school experiences of physical education are compared. Both studies focused on diaspora communities, Greek Turkish girls and British Asian women, living in predominantly non-Muslim countries. Growing concerns about global divisions between 'Muslims and the West' make this a particularly pertinent study. Qualitative data were collected by interviews with 24 Greek Muslim women, and 20 British Muslim women. \ud <P> \ud Physical education has national curriculum status and a similar rationale in both countries but with different cultures of formality and tradition, which impacted on pupils' experiences. Data suggested that Greek and British groups held positive views towards physical education but were restricted on their participation in extra-curricular activities. For the British women religious identity and consciousness of Islamic requirements were more evident than for the Greek women. Differences in stages of acculturation, historical and socio-cultural contexts contributed to less problematic encounters with physical education for Greek Muslims who appeared more closely assimilated into the dominant culture

    Developments in Practice X: Radio Frequency Identification (RFID) - An Internet for Physical Objects

    Get PDF
    This paper explores the applications and future commercial impacts of radio frequency identification (RFID) technology. Its objective is to summarize the ways in which organizations and academics are thinking about these technologies and to stimulate strategic thinking about their possible uses and implications. It first provides an overview of this technology and how it works. Then it explores the surprisingly wide variety of current applications of RFID. Next it looks at several classes of potential RFID applications and how these might affect how organizations work. Finally, it examines the cost and implementation considerations of this technology. The paper concludes that RFID is a viable technology with many possible applications. However, only some of the impacts on organizations and society can be anticipated at present

    Characterization of 40-Gbit/s pulses generated using a lithium niobate modulator at 1550 nm using frequency resolved optical gating

    Get PDF
    The characteristics of 40-Gbit/s pulses generated by exploiting the nonlinear characteristics of a Mach-Zender Lithium Niobate modulator are presented. A high spectral resolution frequency resolved optical gating apparatus has been developed to allow for the complete characterization of the intensity and phase of these pulses. The use of these measurements to simplify the design and optimization of an 80-Gbit/s pulse source, based on this 40-Gbit/s source followed by a nonlinear fiber compressor and multiplexer, is also demonstrated

    Employee participation and engagement in working for the environment

    © Emerald Group Publishing Limited. Purpose – The purpose of this paper is to explore the role of specific human resource management (HRM) practices in the implementation of environmental initiatives in terms of their impact on employee attitudes to the organization and to its environmental programme. Design/methodology/approach – The study used a mixed method approach comprising a survey of 675 employees and 16 semi-structured interviews undertaken across two organizations. Findings – Survey data, analysed using path analysis, showed that participation in environmental initiatives is directly associated with higher levels of employee engagement with the organization, higher rating of their organization’s environmental performance, and lower intention to quit. The qualitative study supports the quantitative data, also highlighting other aspects of environmental initiatives that may affect employee attitudes. Research limitations/implications – Future study should either collect longitudinal data or rely on data collected from two waves of data collection. Objective performance data should also be collected in order to better understand the causal effect of HRM on environmental performance. Practical implications – Our findings have implications for the business case for sustainability,  providing some evidence that implementing environmental initiatives with HRM support may not only motivate staff around environmental programmes but may provide wider benefits for organizations in terms of overall job satisfaction and employee retention. Social implications – Successful implementation of environmental management initiatives have both organizational and employee level outcomes. Employees who were more aligned with their organizational environmental objectives were found to be more engaged and less likely to quit. Originality/value – This study provided both quantitative and qualitative empirical evidence to support the importance of integrating the HRM function into the implementation of environmental initiatives

    Governance of environmental risk: New approaches to managing stakeholder involvement

    Full text link
    Disputes concerning industrial legacies such as the disposal of toxic wastes illustrate changing pressures on corporations and governments. Business and governments are now confronted with managing the expectations of a society increasingly aware of the social and environmental impacts and risks associated with economic development and demanding more equitable distribution and democratic management of such risks. The closed managerialist decision-making of the powerful bureaucracies and corporations of the industrial era is informed by traditional management theory which cannot provide a framework for the adequate governance of these risks. Recent socio-political theories have conceptualised some key themes that must be addressed in a more fitting approach to governance. We identify more recent management and governance theory which addresses these themes and develop a process-based approach to governance of environmental disputes that allows for the evolving nature of stakeholder relations in a highly complex multiple stakeholder arena. © 2008 Elsevier Ltd.

    Commuting symmetry operators of the Dirac equation, Killing-Yano and Schouten-Nijenhuis brackets

    Full text link
    In this paper we derive the most general first-order symmetry operator commuting with the Dirac operator in all dimensions and signatures. Such an operator splits into Clifford even and Clifford odd parts which are given in terms of odd Killing-Yano and even closed conformal Killing-Yano inhomogeneous forms respectively. We study commutators of these symmetry operators and give necessary and sufficient conditions under which they remain of the first-order. In this specific setting we can introduce a Killing-Yano bracket, a bilinear operation acting on odd Killing-Yano and even closed conformal Killing-Yano forms, and demonstrate that it is closely related to the Schouten-Nijenhuis bracket. An important non-trivial example of vanishing Killing-Yano brackets is given by Dirac symmetry operators generated from the principal conformal Killing-Yano tensor [hep-th/0612029]. We show that among these operators one can find a complete subset of mutually commuting operators. These operators underlie separability of the Dirac equation in Kerr-NUT-(A)dS spacetimes in all dimensions [arXiv:0711.0078].Comment: 37 pages, no figure
