Various Perspectives (various + perspective)
Selected AbstractsValidity in action research: a discussion on theoretical and practice issues encountered whilst using observation to collect dataJOURNAL OF ADVANCED NURSING, Issue 3 2001Christopher Turnock MSc MPhil DANS DPSN RN Validity in action research: a discussion on theoretical and practice issues encountered whilst using observation to collect data Aim.,The paper contributes to an understanding of validity in action research methodology by examining issues arising from our attempts to describe the role of an observer in an action research study. Background.,Our experiences in observing patient care in intensive care settings are used to illuminate discussion on the nature of validity in action research. Content.,The paper examines the nature of validity in action research methodology before briefly describing a study that included observing intensive care staff providing patient care. Various perspectives on observation as a research method are critically examined. These include observer role, level of participation, use of cover, structure and timing of observation. Validity in action research underpins the discussion in the paper. Conclusion.,We conclude that it may not always be possible to categorize the role of the observer within existing definitions. It may be better to summarize the actual observer role as a way of illustrating validity so that the reader can judge the validity of the findings from an action research study. [source] Taking It to the Extreme: The Effect of Coalition Cabinets on Foreign PolicyFOREIGN POLICY ANALYSIS, Issue 1 2008Juliet Kaarbo Institutional constraints have been offered by some scholars as an explanation for why multiparty coalitions should be more peaceful than single-party cabinets. Yet others see the same institutional setting as a prescription for more aggressive behavior. Recent research has investigated these conflicting expectations, but with mixed results. We examine the theoretical bases for these alternative expectations about the effects of coalition politics on foreign policy. We find that previous research is limited theoretically by confounding institutional effects with policy positions, and empirically by analyzing only international conflict data. We address these limitations by examining cases of foreign policy behavior using the World Event/Interaction Survey (WEIS) dataset. Consistent with our observation that institutional constraints have been confounded with policy positions, we find that coalitions are neither more aggressive nor more peaceful, but do engage in more extreme foreign policy behaviors. These findings are discussed with regard to various perspectives on the role of institutions in shaping foreign policy behavior.

[source] Toward an Integrative Theory of Counterproductive Workplace Behavior: A Causal Reasoning PerspectiveINTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1-2 2002Mark J. Martinko Over the past decade, there has been an increase in attention to counterproductive workplace behaviors including violence, stealing, dishonesty, volitional absenteeism, drug and alcohol abuse, and aggression, many of which have been addressed in this special issue. Accompanying the attention to these specific types of behaviors has been a proliferation of theories developed to explain, understand, and manage counterproductive behavior. While these theories have addressed many apparently divergent types of behaviors, many similarities exist between and among these various perspectives. In this article, we integrate these various perspectives into a causal reasoning framework, proposing that individuals' attributions about the causal dimensions of workplace events are a primary factor motivating both the emotions and behaviors that result in counterproductive workplace behaviors. [source] The musculotendinous system of an anguilliform swimmer: Muscles, myosepta, dermis, and their interconnections in Anguilla rostrataJOURNAL OF MORPHOLOGY, Issue 1 2008Nicole Danos Abstract Eel locomotion is considered typical of the anguilliform swimming mode of elongate fishes and has received substantial attention from various perspectives such as swimming kinematics, hydrodynamics, muscle physiology, and computational modeling. In contrast to the extensive knowledge of swimming mechanics, there is limited knowledge of the internal body morphology, including the body components that contribute to this function. In this study, we conduct a morphological analysis of the collagenous connective tissue system, i.e., the myosepta and skin, and of the red muscle fibers that sustain steady swimming, focusing on the interconnections between these systems, such as the muscle-tendon and myosepta-skin connections. Our aim is twofold: (1) to identify the morphological features that distinguish this anguilliform swimmer from subcarangiform and carangiform swimmers, and (2) to reveal possible pathways of muscular force transmission by the connective tissue in eels. To detect gradual morphological changes along the trunk we investigated anterior (0.4L), midbody (0.6L), and posterior body positions (0.75L) using microdissections, histology, and three-dimensional reconstructions. We find that eel myosepta have a mediolaterally oriented tendon in each the epaxial and hypaxial regions (epineural or epipleural tendon) and two longitudinally oriented tendons (myorhabdoid and lateral). The latter two are relatively short (4.5,5% of body length) and remain uniform along a rostrocaudal gradient. The skin and its connections were additionally analyzed using scanning electron microscopy (SEM). The stratum compactum of the dermis consists of ,30 layers of highly ordered collagen fibers of alternating caudodorsal and caudoventral direction, with fiber angles of 60.51 ± 7.05° (n = 30) and 57.58 ± 6.92° (n = 30), respectively. Myosepta insert into the collagenous dermis via fiber bundles that pass through the loose connective tissue of the stratum spongiosum of the dermis and either weave into the layers of the stratum compactum (weaving fiber bundles) or traverse the stratum compactum (transverse fiber bundles). These fiber bundles are evenly distributed along the insertion line of the myoseptum. Red muscles insert into lateral and myorhabdoid myoseptal tendons but not into the horizontal septum or dermis. Thus, red muscle forces might be distributed along these tendons but will only be delivered indirectly into the dermis and horizontal septum. The myosepta-dermis connections, however, appear to be too slack for efficient force transmission and collagenous connections between the myosepta and the horizontal septum are at obtuse angles, a morphology that appears inadequate for efficient force transmission. Though the main modes of undulatory locomotion (anguilliform, subcarangiform, and carangiform) have recently been shown to be very similar with respect to their midline kinematics, we are able to distinguish two morphological classes with respect to the shape and tendon architecture of myosepta. Eels are similar to subcarangiform swimmers (e.g., trout) but are substantially different from carangiform swimmers (e.g., mackerel). This information, in addition to data from kinematic and hydrodynamic studies of swimming, shows that features other than midline kinematics (e.g., wake patterns, muscle activation patterns, and morphology) might be better for describing the different swimming modes of fishes.

HALVORSEN Background: To shed light on the values and considerations that affect the decision-making processes and the decisions to limit intensive care treatment. Method: Qualitative methodology with participant observation and in-depth interviews, with an emphasis on eliciting the underlying rationale of the clinicians' actions and choices when limiting treatment. Results: Informants perceived over-treatment in intensive care medicine as a dilemma. One explanation was that the decision-making base was somewhat uncertain, complex and difficult. The informants claimed that those responsible for taking decisions from the admitting ward prolonged futile treatment because they may bear guilt or responsibility for something that had gone wrong during the course of treatment. The assessments of the patient's situation made by physicians from the admitting ward were often more organ-oriented and the expectations were less realistic than those of clinicians in the intensive care unit who frequently had a more balanced and overall perspective. Aspects such as the personality and the speciality of those involved, the culture of the unit and the degree of interdisciplinary cooperation were important issues in the decision-making processes. Conclusion: Under-communicated considerations jeopardise the principle of equal treatment. If intensive care patients are to be ensured equal treatment, strategies for interdisciplinary, transparent and appropriate decision-making processes must be developed in which open and hidden values are rendered visible, power structures disclosed, employees respected and the various perspectives of the treatment given their legitimate place. [source] Understanding information related fields: A conceptual frameworkJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 13 2007Ping Zhang Many scientific fields share common interests for research and education. Yet, very often, these fields do not communicate to each other and are unaware of the work in other fields. Understanding the commonalities and differences among related fields can broaden our understanding of the interested phenomena from various perspectives, better utilize resources, enhance collaboration, and eventually move the related fields forward together. In this article, we present a conceptual framework, namely the Information-Model or I-model, to describe various aspects of information related fields. We consider this a timely effort in light of the evolutions of several information related fields and a set of questions related to the identities of these fields. It is especially timely in defining the newly formed Information Field from a community of twenty some information schools. We posit that the information related fields are built on a number of other fields but with their own unique foci and concerns. That is, core components from other fundamental fields interact and integrate with each other to form dynamic and interesting information related fields that all have to do with information, technology, people, and organization/society. The conceptual framework can have a number of uses. Besides providing a unified view of these related fields, it can be used to examine old case studies, recent research projects, educational programs and curricula concerns, as well as to illustrate the commonalities and differences with the information related fields. [source] Blowing hot and cold on project managementPROJECT MANAGEMENT JOURNAL, Issue 3 2010Christophe N. Bredillet Abstract The purpose of this article is to suggest a possible "meta" approach of the project management field,the unit of analysis,respectful of the various perspectives in existence, while providing an integrative ontological and epistemological framework. In order to do so, I first suggest what could be perceived as being the state of the field and its main constituting "school of thoughts." Then I open the debate on what could be the ontological and epistemological perspectives enabling us to better take into account the diversity we face in considering the richness of the field. Based on these developments, I propose to address project management as a complex integrative knowledge field, which eventually will lead us to consider "modeling,developing specific convention,to do ingeniously" as acting and learning mode in the management of projects. [source] Integrated strategies for assessment of metabolite exposure in humans during drug development: analytical challenges and clinical development considerationsBIOPHARMACEUTICS AND DRUG DISPOSITION, Issue 4 2009Mingshe Zhu Abstract Monitoring the exposure of a drug and its metabolites in humans and preclinical species during drug development is required to ensure that the safety of drug-related components in humans are adequately assessed in the standard toxicology studies. Recently published FDA guidance on metabolites in safety testing (MIST) has generated broad discussion from various perspectives. Most of the opinions and experiences shared among the scientific community are scientifically sound and practical. There are various approaches to assess the metabolite exposure margin between toxicology species and humans: either by direct or indirect comparison or by qualitative or quantitative comparison. The choice of when and how to pursuit metabolite assessment is based on the overall development strategy of the compound. Therefore, it is important to understand the utility and limitations of analytical instruments in order to apply an appropriate analytical tool to address specific questions posed at different stages of drug development. The urgency of metabolite monitoring depends on the intrinsic nature of the compound, therapeutic intent and objective of the clinical development. The strategy for assessing metabolite exposure in humans should be a holistic approach considering clinical situations and cumulative knowledge of the metabolism of the drug in order to appropriately address metabolite safety in humans. A one-size-fits-all approach is rarely the best use of resources. Copyright © 2009 John Wiley & Sons, Ltd. [source] Checking the Map: Critiquing Joanne Martin's Metatheory of Organizational Culture and Its Uses in Communication ResearchCOMMUNICATION THEORY, Issue 3 2006Bryan C. Taylor Joanne Martin's scholarship has significantly influenced the study of organizational culture by communication scholars. Martin's recent metatheory seeks to "map" the "terrain" of perspectives commonly used to study organizational culture and argues for the use of multiple perspectives to produce more fruitful research. While acknowledging the benefits of this metatheory, we critique 2 of its problematic elements. Both arise from Martin's claims about the phenomena of organizational culture and the various perspectives through which they might be known. The first problem involves Martin's decoupling of ontology and epistemology, as well as her subsequent oscillation between 2 conflicting clusters of "onto-epistemological" claims. Partly as a result, Martin also overemphasizes the ideational dimensions of organizational culture, thereby inhibiting analysis of its production in and through communication. These problems may negatively affect how communication scholars conceptualize organizational cultural phenomena and analyze data. To mitigate these problems, we offer 2 readings derived from social constructionism, poststructuralism, and critical realism. These readings aid communication scholars in successfully using Martin's metatheory. We conclude by considering the implications of this critique for the development of metatheory in communication.
