Radiative transfer in moving media II. Solution of the radiative transfer equation in axial symmetry
A new method for the formal solution of the 2D radiative transfer equation in
axial symmetry in the presence of arbitrary velocity fields is presented. The
combination of long and short characteristics methods is used to solve the
radiative transfer equation. We include the velocity field in detail using the
Local Lorentz Transformation. This allows us to obtain a significantly better
description of the photospheric region, where the gradient of the global
velocity is too small for the Sobolev approximation to be valid. Sample test
calculations for the case of a stellar wind and a rotating atmosphere are
presented.Comment: 11 pages, 19 figures. accepted by Astronomy and Astrophysic
Perspectives on the police profession: an international investigation
Purpose
– The purpose of this paper is to clarify the diversity of professional perspectives on police culture in an international context.
Design/methodology/approach
– In a first step the authors developed a standardized instrument of 45 occupational features for comparative analysis of police professional views. This set was inductively created from 3,441 descriptors of the police profession from a highly diverse sample of 166 police officers across eight European countries. Using this standardized instrument, Q-methodological interviews with another 100 police officers in six European countries were conducted.
Findings
– The authors identified five perspectives on the police profession suggesting disparities in officers’ outlooks and understanding of their occupation. Yet, the findings also outline considerable overlaps in specific features considered important or unimportant across perspectives.
Research limitations/implications
– The study emphasizes that police culture needs to be described beyond the logic of distinct dimensions in well-established typologies. Considering specific features of the police profession determines which aspects police officers agree on across organizational and national contexts and which aspects are unique.
Practical implications
– The feature-based approach provides concrete pointers for the planning and implementation of (inter)national and inter-organizational collaborations as well as organizational change.
Originality/value
– This study suggests an alternative approach to investigate police culture. It further offers a new perspective on police culture that transcends context-specific boundaries
Short stature : investigation and detection of growth-hormone-deficience
Este artigo discute as definições de baixa estatura e descreve caracterĂsticas clĂnicas e laboratoriais de suas principais causas, enfatizando principalmente o diagnĂłstico da deficiĂŞncia de hormĂ´nio de crescimento atravĂ©s da medida de IGF-1 e da interpretação de testes de estĂmulo do GH. Sugere um fluxograma diagnĂłstico a ser utilizado na avaliação de crianças com baixa estatura.This paper discuss the definition of short stature and describes clinical and biochemical characteristics of the most important associated disturbances, specially the growth hormone deficiency. For this diagnosis, we emphasize the application the IGF-1 measure and the GH-clonidine stimulation test. In conclusion, we suggest a standard protocol evaluation for use in the routine evaluation of the children with short stature
Knowledge sharing practices and issues in policing contexts: a systematic review of the literature.
The effective sharing of knowledge both within and between police organizations is arguably becoming increasingly vital for success and has driven research in a disparate range of fields. This paper therefore presents the results of an integrative systematic literature review of research into knowledge sharing within and between police organizations across Europe. The 39 papers analysed
were drawn from English-language studies published between 2000 and 2013, complemented by additional searches for non-English language papers in nine European countries. Analyses showed that past research has focused on intra-organizational knowledge sharing, with a particular spotlight on criminal intelligence and technology. Barriers / enablers of knowledge sharing were grouped into
knowledge management strategy/legislation, technology, culture and loss of knowledge themes. Research recommendations include exploring the role of leadership and examination of police knowledge sharing across regional, institutional and international boundaries. Practical recommendations include having procedural clarity in systems, policies for sharing knowledge and developing
the relevant knowledge, skills and motivation of police personnel through appropriate training.
