Greater Complexity (greater + complexity)
Selected AbstractsFocus group composition: a comparison between natural and constructed groupsAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2001Julie Leask Objective: To provide insight into the effects of focus group composition. Method: In an early phase of an ongoing study of parental reception to messages about childhood immunisation, we conducted four focus groups; two with participants who had never met before (constructed groups) and two with participants who were part of a preestablished first-time mothers' group (natural groups). Results: Marked differences were noted in the group dynamics, depth of interaction and diversity between groups. Discussions with constructed groups were animated, enthusiastic, expressed more divergent views and articulated greater complexities of the topic. Discussions with natural groups were generally flatter and less enthusiastic, displaying a higher level of apparent conformity to conventional wisdom. The need to protect other participants from potentially disturbing information about vaccination was expressed across groups but acted to censor natural groups, where participants knew more of each others' sensitivities. Implications: Insight into the factors contributing to such differences may enhance understanding of the contexts in which constructed groups are more appropriate. The processes of social censorship may be of primary interest to the researcher. However, where it is paramount to elicit a range of opinions about a potentially controversial topic, we suggest that natural groups in the delicate stage of norming be avoided. The peculiarities of each individual research circumstance are best explored in pilot studies. [source] Social Welfare and the Selection of the Optimum Hog Slaughter Weight in QuebecCANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 3 2003Peter D. Goldsmith What is the optimum slaughter weight? It depends from whose perspective. A dynamic systems model is built to analyze the welfare impact of alternative animal genetics, feeding program, feed quality and slaughter weight on producers, processors and the environment. The unique systems approach analyzes eight possible welfare rules and a corresponding harm function to assess animal performance within a multistakeholder context. The model results show there are significant tradeoff problems among producers, processors and the environment. The model highlights how the definition of animal performance needs to be revisited, as it has different meaning to different stakeholders in society. While performance historically was synonymous with production efficiency, with new social and political concerns, this interpretation is not universal. The model demonstrates greater complexities by broadening the set of affected parties. Quel est lepoids d'abattage optimal? Cela dépend du point de vue adopté. Une modélisation à base de systèmes dynamiques est construite afin d'analyser l'impact de méthodes alternatives en matière de génétique animale, de programme alimentaire, de qualité de l'aliment et du poids à l'abattage, sur les producteurs, les transformateurs et sur l'environnement. L'approche unique par systèmes analyse huit règles possibles concernant le bien-être social ainsi qu'une fonction correspondante aux nuisances associées pour mesurer la performance animale dans le contexte où plusieurs parties prenantes sont présentes. Les résultats du modèle mettent en avant des problèmes de compromis significatifs parmi les producteurs, les transformateurs et pour l'environnement. Le modèle souligne combien la définition de la performance animale a besoin d'être revue et corrigée étant donnée que les différentes parties concernées dans la société la perçoivent différemment. Alors que, historiquement, performance était synonyme d'efficacité de la production, avec les nouvelles préoccupations sociales et politiques, la définition de « performance » n'est plus universelle. Le modèle présenté ici illustre une plus grande complexité en augmentant l'ensemble des parties concernées. [source] Leaf Processing by Wild Chimpanzees: Physically Defended Leaves Reveal Complex Manual SkillsETHOLOGY, Issue 8 2002Nadia Corp The manual processing of eight species of leaf was investigated in the M-group chimpanzees of Mahale Mountains National Park, Tanzania. Leaf species varied in the extent to which physical defences made consumption difficult. In all, 96 distinct techniques for leaf processing were identified, but two species with defended leaves (Ficus asperifolia and F. exasperata) required 2.5 as many techniques as did any of the six undefended species. Moreover, chimpanzees made more multiple leaf detachments, and made more subsequent modifications of the leaves, when dealing with the leaves of these two Ficus species, compared with the undefended leaf species. This greater complexity was associated with evidence of flexible, hierarchical organization of the process: iteration of modules consisting of several processing elements, facultative omission of modules, or substitutions of alternative modules. Comparison with data from mountain gorillas is made, and is consistent with similar cognitive architecture in the two species. We consider that, not only is hierarchical organization currently associated with mechanical difficulty in food processing, but that over evolutionary time-scales difficulties in food processing may have selected for cognitive advance. [source] Digital algorithm for distance relay including grounding impedance at fault placeEUROPEAN TRANSACTIONS ON ELECTRICAL POWER, Issue 4 2002Z. M. Radojevi The influence of the fault place grounding impedance in algorithms for ground faults distance relay is not usually taken into account. The fault place grounding impedance depends on design characteristics of the ground wire and towers footing resistance. This paper shows a possibility of taking into account the fault place grounding impedance in the algorithm for the ground fault distance relay. The algorithm taking into consideration the fault place grounding impedance has better accuracy and only slightly greater complexity. [source] Citizenship and Female Catholic Militancy in 1920s SpainGENDER & HISTORY, Issue 3 2007Inmaculada Blasco Herranz The aim of this article is to offer a new interpretation of the role of women in the Catholic movement in 1920s Spain. It responds to historical analyses that view this mobilisation as the product of clerical manipulation and that consider its feminist aspects to be flawed. The new interpretation presented here is based on a notion of citizenship understood as both a process and as a form of identity construction, and which was configured historically as a result of the incorporation of modern ideas of women, the nation and religion. As a result, this analysis examines the relationship between Catholicism and modernity in greater complexity than the dichotomous views frequently encountered in Spanish historiography. [source] Community mental health nursing: Keeping pace with care delivery?INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 3 2008Julie Henderson ABSTRACT:, The National Mental Health Strategy has been associated with the movement of service delivery into the community, creating greater demand for community services. The literature suggests that the closure of psychiatric beds and earlier discharge from inpatient services, have contributed to an intensification of the workload of community mental health nurses. This paper reports findings from the first stage of an action research project to develop a workload equalization tool for community mental health nurses. The study presents data from focus groups conducted with South Australian community mental health nurses to identify issues that impact upon their workload. Four themes were identified, relating to staffing and workforce issues, clients' characteristics or needs, regional issues, and the impact of the health-care system. The data show that the workload of community mental health nurses is increased by the greater complexity of needs of community mental health clients. Service change has also resulted in poor integration between inpatient and community services and tension between generic case management and specialist roles resulting in nurses undertaking tasks for other case managers. These issues, along with difficulties in recruiting and retaining staff, have led to the intensification of community mental health work and a crisis response to care with less time for targeted interventions. [source] Comparing academic and community-based hospitalists,JOURNAL OF HOSPITAL MEDICINE, Issue 6 2010David Malkenson BS Abstract In 2006, hospitalist programs were formally introduced at both an academic and community hospital in the same city providing an opportunity to study the similarities and differences in workflows in these two settings. The data were collected using a time-flow methodology allowing the two workflows to be compared quantitatively. The results showed that the hospitalists in the two settings devoted similar proportions of their workday to the task categories studied. Most of the time was spent providing indirect patient care followed by direct patient care, travel, personal, and other. However, after adjusting for patient volumes, the data revealed that academic hospitalists spent significantly more time per patient providing indirect patient care (Academic: 54.7 ± 11.1 min/patient, Community: 41.9 ± 9.8 min/patient, p < 0.001). Additionally, we found that nearly half of the hospitalists' time at both settings was spent multitasking. Although we found subtle workflow differences between the academic and community programs, their similarities were more striking as well as greater than their differences. We attribute these small differences to the higher case mix index at the academic program as well greater complexity and additional communication hand-offs inherent to a tertiary academic medical center. It appears that hospitalists, irrespective of their work environment, spend far more time documenting, communicating and coordinating care than they do at the bedside raising the question, is this is a necessary feature of the hospitalist care model or should hospitalists restructure their workflow to improve outcomes?

[source] Spermatozoal ultrastructure in three Atlantic solenocerid shrimps (Decapoda, Dendrobranchiata)JOURNAL OF MORPHOLOGY, Issue 3 2006Antonio Medina Abstract The spermatozoal ultrastructure in three solenocerid shrimps (Solenocera membranacea, S. africana, and Pleoticus muelleri) from different Atlantic locations was examined with the aim of increasing understanding of the phylogenetic relationships in the Dendrobranchiata. A considerable structural similarity between the sperm of these species and those of penaeid shrimps supports a close affinity between the Penaeidae and Solenoceridae. However, significant differences in the sperm morphology of the previously investigated sicyoniids (namely, a greater complexity of the acrosomal complex) suggest evolutionary separation of the Sicyoniidae from the assemblage Penaeidae-Solenoceridae. Two ultrastructural features distinguish the spermatozoa of the three studied solenocerids from penaeid sperm: 1) separation of the plasma and acrosome membranes at the base of the spike and anterior region of the cap, and 2) asymmetry of the acrosomal cap, which appears to be a synapomorphy of the group. No striking ultrastructural differences were found between the spermatozoa of the closely related species S. membranacea and S. africana, whereas a great number of morphological differences separate the spermatozoa of Pleoticus from those of Solenocera (e.g., shape of the acrosomal cap, structural arrangement of the contents of the whole acrosome vesicle, thickness and distribution of the cytoplasm, and external shape of the spike).

[source] Managed socialization: how smart companies leverage global knowledgeKNOWLEDGE AND PROCESS MANAGEMENT: THE JOURNAL OF CORPORATE TRANSFORMATION, Issue 3 2007Deependra Moitra Driven by economic and market forces, the last 2 decades have witnessed a phenomenal acceleration in the pace of globalization. Today, globalization, and particularly globalization of knowledge work, has emerged as a business necessity. In their quest for competitiveness, more and more companies are leveraging global resources by distributing knowledge work across borders and essentially establishing around-the-clock innovation engines. Yet, managing knowledge,the most valuable resource of the new economy enterprises,remains to be a formidable business challenge to deal with. This challenge assumes even greater complexity in the context of globalization, characterized by distance, language barriers, cultural diversity, and a host of other socio-political factors. Whilst there have been considerable developments in the discipline of knowledge management, much of that does not quite alleviate the struggle companies face in effectively harnessing global knowledge. Specifically, while much progress has been made in managing explicit knowledge, firms find it hard to capture and leverage the tacit knowledge, which holds the key to knowledge-based competition. This paper argues that this inability to capitalize on the tacit knowledge stems from a missing ,social' dimension in the design of knowledge management strategies, which when addressed leads to unleashing the valuable tacit knowledge. Drawing on real-world research spanning 12 leading companies, in this paper we discuss Managed Socialization,the most vital management process for harnessing global knowledge. We argue that only by instituting managed socialization firms can truly succeed in leveraging global knowledge. Toward that, we describe the various elements that constitute managed socialization and based on case studies distil actionable insights that firms can capitalize on to fuel their quest for global dominance.

[source] VERTEBRAL OSTEOLOGY AND COMPLEXITY IN LAGENORHYNCHUS ACUTUS (DELPHINIDAE) WITH COMPARISON TO OTHER DELPHINOID GENERAMARINE MAMMAL SCIENCE, Issue 3 2005Emily A. Buchholtz Abstract The vertebral column of the Atlantic white-sided dolphin, Lagenorhynchus acutus, reflects the radical reorganization of the cetacean column for locomotion in water. Both posterior thoracic and anterior caudal vertebrae have been "lumbarized," and discontinuities occur within the caudal series at the synclinal point and fluke base. Morphology changes subtly as body size increases. Neural process height increases more rapidly, and centrum length more variably, than other vertebral parameters. As a result, large animals have disproportionately tall neural processes, short necks, long mid-body regions, and short flukes. Vertebral columns of large animals also show greater complexity (range, irregularity, and polarization) of centrum length than do those of smaller animals. Comparisons among dolphins reveal that complexity trends with respect to differentiation of parts run counter to the trend with respect to number of parts, a relationship predicted by Williston in 1914. [source] Looking through the eyes of fungi: molecular genetics of photoreceptionMOLECULAR MICROBIOLOGY, Issue 1 2007Alfredo Herrera-Estrella Summary Filamentous fungi respond to a variety of environmental signals. One of them is light, providing critical information about orientation, or impending stress. Cells of filamentous fungi appear to sense blue light through a unique transcription factor that has a flavin chromophore and activates its targets in a light-dependent manner, the white collar (WC) complex. Fungal photophysiology, though, predicted a greater complexity of responses to the whole visible spectrum. The rapidly growing fungal genome database provides candidates to explain how fungi see not only blue, but also near-UV, green and red light. At the same time, there are surprises in the genomes, including photoreceptors for which there are no obvious photoresponses. Linking these genes and their functions will help understand how a list of only a few biological chromophores accounts for such a diversity of responses. At the same time, deeper mechanistic understanding of how the WC complex functions will lead to fundamental insights at the point where the environment impinges, in this case in the form of photons, on the transcriptional machinery of the cell. [source] Flexibility: A Concept AnalysisNURSING FORUM, Issue 1 2000Michele August-Brady RN Flexibility is a quality that is deemed essential for nursing as the healthcare environment escalates into greater complexity. The word "flexibility" appears in nursing literature addressing the need to prepare for the next millenium, yet the concept of flexibility is rarely defined. Other disciplines, such as engineering, have struggled for years and continue to struggle to achieve conceptual clarity with regard to flexibility. A concept analysis using Rodgers' evolutionary method was undertaken to understand the meaning of flexibility. [source] Does avian species richness in natural patch mosaics follow the forest fragmentation paradigm?ANIMAL CONSERVATION, Issue 1 2007D. C. Pavlacky Jr. Abstract As one approaches the north-eastern limit of pinyon (Pinus spp.) juniper (Juniperus spp.) vegetation on the Colorado Plateau, USA, woodland patches become increasingly disjunct, grading into sagebrush (Artemisia spp.)-dominated landscapes. Patterns of avian species richness in naturally heterogeneous forests may or may not respond to patch discontinuity in the same manner as bird assemblages in fragmented agricultural systems. We used observational data from naturally patchy woodlands and predictions derived from studies of human-modified agricultural forests to estimate the effects of patch area, shape, isolation and distance to contiguous woodland on avian species richness. We predicted that patterns of species richness in naturally patchy juniper woodlands would differ from those observed in fragmented agricultural systems. Our objectives were to (1) estimate the effect of naturally occurring patch structure on avian species richness with respect to habitat affinity and migratory strategy and (2) assess the concordance of the effects to predictions from agricultural forest systems. We used the analogy between populations and communities to estimate species richness, where species are treated as individuals in the application of traditional capture,recapture theory. Information-theoretic model selection showed that overall species richness was explained primarily by the species area relationship. There was some support for a model with greater complexity than the equilibrium theory of island biogeography where the isolation of large patches resulted in greater species richness. Species richness of woodland-dwelling birds was best explained by the equilibrium hypothesis with partial landscape complementation by open-country species in isolated patches. Species richness within specific migratory strategies showed concomitant increases and no shifts in species composition along the patch area gradient. Our results indicate that many patterns of species richness considered to be fragmentation effects may be general consequences of patch discontinuity and are ubiquitous in naturally heterogeneous systems. There was no evidence for the effects of patch shape and distance to contiguous woodland in juniper woodland, suggesting edge effects and dependence upon regional species pools are characteristics of fragmented agricultural systems. Natural patch mosaics may provide benchmarks for evaluating fragmentation effects and managing forests by mimicking natural landscape patterns. [source] Digital Solipsisim and the Paradox of the Great ,Forgetting'ARCHITECTURAL DESIGN, Issue 4 2010Neil Spiller Abstract Neil Spiller counters the main theme of this issue by questioning the dominant focus on production and new technologies in architectural culture, which places a premium on the generation of ,ever more gratuitous complex surfaces and structures'. Could this inward-looking emphasis on process and obsessive love of new technologies be at the expense of the final product? Are we in danger of producing artefacts that lose sight of human expression and poetics in the competitive drive for greater complexity? Are we, in fact, heading towards a great ,forgetting' in which humanity is subtracted from the architectural product? [source] | |||||||||||||||||||
