[source] Anatomy of Autonomy: Assessing the Organizational Capacity and External Environment of the Autonomous Region in Muslim MindanaoASIAN POLITICS AND POLICY, Issue 2 2009Benedict S. Jimenez Decentralization and autonomy can potentially increase public sector efficiency, effectiveness, and accountability, as well as fulfill a conflict-mitigating role. There is no guarantee, however, that decentralization, once implemented, would automatically produce the expected benefits. Using the case of the Autonomous Region in Muslim Mindanao (ARMM) in the Philippines, this article explores the importance of organizational capacity and the cultural, political, and social conditions in the region to explain the performance of the autonomous government. The article concludes that for autonomy to work, the administrative and institutional capacity of the regional government should be revitalized and the current politico-administrative structure redesigned to accommodate local customs and practices and facilitate a consultative and collegial local governance arrangement. [source] Determinants of Antenatal Care Utilization in Three Rural Areas of VietnamPUBLIC HEALTH NURSING, Issue 4 2007Lieu Thi Thuy Trinh ABSTRACT Objective: To identify factors associated with any use of antenatal care (ANC), gestational age at entry to ANC, number of visits, and overall ANC utilization in the three provinces of Long an, Ben tre, and Quang ngai. Data: The Vietnam-Australia Primary Health Care Project conducted cross-sectional surveys in 1998,1999. Data from 1,335 eligible women were available for analysis. Methods: Explanatory variables were selected using the Andersen Health Seeking Behavior Model and analyzed using multivariate regression techniques. Results: External environment, predisposing characteristics, and need, which existed before contact with ANC providers, were most related to using any ANC and gestational age at entry to ANC. However, ANC services provided to women and personal health care during pregnancy, which could have resulted from initial contact with ANC providers, were most related to continuation of ANC visits and overall ANC utilization. Significant variability in the use of ANC existed between provinces and between subsets of women in each province. Conclusion: To have more women who attend ANC and attend early, promotion should be targeted at high-risk groups of women. However, to improve the number of ANC visits and overall utilization, the quality of ANC services should be improved. [source] The Proportion and Social Capital of Outside Directors and Their Impacts on Firm Value: evidence from KoreaCORPORATE GOVERNANCE, Issue 6 2007Yangmin Kim This study examines the effects of outside directors' proportion and their social capital on firm value using a sample of 473 large, publicly traded Korean companies from 1998 through 2003. Outside director proportion, which is defined as the ratio of outside directors to the total number of directors of a company, is regarded as a proxy of board independence. Outside director social capital, which is defined as the degree to which outside board members have outside contacts in the external environment, is regarded as a proxy of board's ability to extract valuable resources or information from the environment. It is hypothesised that both the proportion of outside directors to the total directors and outside director social capital will be positively associated with firm value. This study reports strong GLS evidence of the relationship between outside director social capital and firm value but no significant relationship between outside director proportion and firm value. [source] The Implementation of Innovation by a Multinational Operating in Two Different Environments: A Comparative StudyCREATIVITY AND INNOVATION MANAGEMENT, Issue 2 2002Mohamed Zain The aim of the paper is to examine the innovation initiatives and processes followed by two subsidiaries of a German multinational company operating in Europe and Asia and to compare the innovativeness of their operations in these two locations. The study examined the innovation processes followed by the two subsidiary firms operating in Germany and Malaysia, the actual problems faced by them, the critical success factors involved in the implementation, and the work climates of the firms. Interestingly, it was found that both firms followed similar innovation processes. Nevertheless, different types of problems and critical success factors were applicable to both firms. The results showed that the Malaysian subsidiary faced more behavioural problems while the German subsidiary encountered more technical problems. Further, the study showed that a lack of knowledge was the common problem faced equally by both firms. The study demonstrated that the German subsidiary had better working climate compared to its counterpart in Malaysia. Finally, the German subsidiary was found to be more innovation,active than the Malaysian subsidiary as it introduced more types of innovation, interacted with more types of entity in the external environment and introduced more types of training. [source] Exploring the Link between Dominant Logic and Company PerformanceCREATIVITY AND INNOVATION MANAGEMENT, Issue 2 2000Georg Von Krogh To revitalize the discussion on dominant logic our paper aims to establish the forgotten link between dominant logic and firm performance. To do so, the concept is enhanced conceptually and operationalized by developing a framework including firms' conceptualization of the business (external environment) and of themselves (internal environment) and performance. The framework is applied to a longitudinal study of two consumer electronics firms. The empirical evidence shows that differences in dominant logic lead to different strategic reactions to developments in the industry, and thus result in performance differences. [source] What drives cell morphogenesis: A look inside the vertebrate photoreceptorDEVELOPMENTAL DYNAMICS, Issue 9 2009Breandán Kennedy Abstract Vision mediating photoreceptor cells are specialized light-sensitive neurons in the outer layer of the vertebrate retina. The human retina contains approximately 130 million of such photoreceptors, which enable images of the external environment to be captured at high resolution and high sensitivity. Rod and cone photoreceptor subtypes are further specialized for sensing light in low and high illumination, respectively. To enable visual function, these photoreceptors have developed elaborate morphological domains for the detection of light (outer segments), for changing cell shape (inner segments), and for communication with neighboring retinal neurons (synaptic terminals). Furthermore, rod and cone subtypes feature unique morphological variations of these specialized characteristics. Here, we review the major aspects of vertebrate photoreceptor morphology and key genetic mechanisms that drive their formation. These mechanisms are necessary for cell differentiation as well as function. Their defects lead to cell death. Developmental Dynamics 238:2115,2138, 2009. © 2009 Wiley-Liss, Inc. [source] Effects of maternal style on infant behavior in Japanese macaques (Macaca fuscata)DEVELOPMENTAL PSYCHOBIOLOGY, Issue 4 2002Massimo Bardi Abstract We assessed the association of maternal style and infant behavior of group-living Japanese macaques during the first year of infant development. We tested the hypothesis that different mothering styles were correlated with the behavioral repertoire of infants at three different developmental stages. We expected that infants of rejecting mothers would show a higher level of enterprise and that infants of protective mothers would be less interested in the external environment. We found evidence that maternal style affects infant behavior during the early developmental phase, but this influence becomes smaller as the infant grows older and approaches complete independence. Maternal protectiveness appears to have long-lasting effects on infant exploration as infants of protective mothers tended to be less attracted by the external environment. On the other hand, mater- nal rejection appears to have long-lasting effects on infant interaction with other group members as more rejected infants tended to initiate a significantly higher number of contacts with other juveniles and adults. These results suggest that both maternal rejection and maternal protectiveness play an important role in the independence of the offspring, in opposite directions. That is, rejection promotes independence whereas protectiveness delays it. © 2002 Wiley Periodicals, Inc. Dev Psychobiol 41: 364,372, 2002.

Holland Abstract In amphioxus larvae, the club-shaped gland is a tube connecting the pharyngeal lumen with the external environment. The functions of the gland and its fate during the larva-to-juvenile metamorphosis have long been controversial. Here we use a fixative including ruthenium red to preserve extracellular secretions (presumably glycoproteins) in late pre-metamorphic larvae. This procedure reveals reddish, fibrogranular material in the lumen of the club-shaped gland and in the pharynx adjacent to the gland's inner opening. This finding strengthens the idea that secretions of the club-shaped gland are exported to the pharyngeal lumen to help form a mucous trap for capturing food particles entering the mouth. We also use the terminal desoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) assay to study apoptosis in the tissues of metamorphosing larvae. One of the earliest events of metamorphosis is the massive apoptotic destruction of the club-shaped gland. Therefore, despite some previous opinions to the contrary, the cells of the gland do not survive to participate in the genesis of the definitive endostyle or any other post-larval structures. [source] Reliability and repeatability of thermographic examination and the normal thermographic image of the thoracolumbar region in the horseEQUINE VETERINARY JOURNAL, Issue 4 2004B. V. TUNLEY Summary Reasons for performing study: Thermographic imaging is an increasingly used diagnostic tool. When performing thermography, guidelines suggest that horses should be left for 10,20 mins to ,acclimatise' to the thermographic imaging environment, with no experimental data to substantiate this recommendation. In addition, little objective work has been published on the repeatability and reliability of the data obtained. Thermography has been widely used to identify areas of abnormal body surface temperature in horses with back pathology; however, no normal data is available on the thermographic ,map' of the thoracolumbar region with which to compare horses with suspected pathology. Objectives: To i) investigate whether equilibration of the thermographic subject was required and, if so, how long it should take, ii) investigate what factors affect time to equilibration, iii) investigate the repeatability and reliability of the technique and iv) generate a topographic thermographic ,map' of the thoracolumbar region. Methods: A total of 52 horses were used. The following investigations were undertaken: thermal imaging validation, i.e. detection of movement around the baseline of an object of constant temperature; factors affecting equilibration; pattern reproducibility during equilibration and over time (n = 25); and imaging of the thoracolumbar region (n = 27). Results: A 1°C change was detected in an object of stable temperature using this detection system, i.e the ,noise' in the system. The average time taken to equilibrate, i.e. reach a plateau temperature, was 39 mins (40.2 in the gluteal region, 36.2 in lateral thoracic region and 40.4 in metacarpophalangeal region). Only 19% of horses reached plateau within 10,20 mins. Of the factors analysed hair length and difference between the external environment and the internal environment where the measurements were being taken both significantly affected time to plateau (P<0.05). However, during equilibration, the thermographic patterns obtained did not change, nor when assessed over a 7 day period. A ,normal' map of the surface temperature of the thoracolumbar region has been produced, demonstrating that the midline is the hottest, with a fall off of 3°C either side of the midline. Conclusions: This study demonstrates that horses may not need time to equilibrate prior to taking thermographic images and that thermographic patterns are reproducible over periods up to 7 days. A topographical thermographic ,map' of the thoracolumbar region has been obtained. Potential relevance: Clinicians can obtain relevant thermographic images without the need for prior equilibration and can compare cases with thoracolumbar pathology to a normal topographic thermographic map. [source] The Emerging Strategic Partnership between India and the EU: A Critical AppraisalEUROPEAN LAW JOURNAL, Issue 6 2007Saponti Baroowa In recent times however, amongst others, the changing external environment, the EU's emerging profile as a global actor and India's growing importance both regionally and globally warranted the need for greater political dialogue and cooperation between the two sides. What followed therefore was the formalisation at the highest level of the EU's political dialogue with India and its institutionalisation into a meaningful summit-level partnership leading to a strategic partnership. Areas of divergence and challenges remain but the opportunities that have surfaced are significant and deserving of attention. This article critically analyses the growing strategic partnership between India and the EU in the light of both these realities. [source] CONCORDANCE OF THE CIRCADIAN CLOCK WITH THE ENVIRONMENT IS NECESSARY TO MAXIMIZE FITNESS IN NATURAL POPULATIONSEVOLUTION, Issue 4 2008Kevin J. Emerson The ubiquity of endogenous, circadian (daily) clocks among eukaryotes has long been held as evidence that they serve an adaptive function, usually cited as the ability to properly time biological events in concordance with the daily cycling of the environment. Herein we test directly whether fitness is a function of the matching of the period of an organism's circadian clock with that of its environment. We find that fitness, measured as the per capita expectation of future offspring, a composite measure of fitness incorporating both survivorship and reproduction, is maximized in environments that are integral multiples of the period of the organism's circadian clock. Hence, we show that organisms require temporal concordance between their internal circadian clocks and their external environment to maximize fitness and thus the long-held assumption is true that, having evolved in a 24-h world, circadian clocks are adaptive. [source] Synergistic regulation of neuropeptide levels by internal and external stimuliEXPERIMENTAL DERMATOLOGY, Issue 9 2004J. Hosoi The skin is the most peripheral organ confronting the external environment. We found that the level of substance P is regulated by both internal and external stimuli. Mock interview induced the acute stress in human assessed by the measurement of serum cortisol. The serum level of substance P increased within 1 h after the mock interview. Interestingly, the increase was suppressed by inhalation of 1,3-dimethoxy-5-methylbenzene. Similar regulation was observed in mice. Furthermore, restraint or the intravenous administration of substance P induced the activation of cutaneous mast cells. Housing under the condition of lower humidity (about 30%) for 24 h caused the increase in the substance P level both in peripheral blood and in the skin. Restraint for 2 h during the housing under the condition of lower humidity increased the substance P level further. The activation of cutaneous mast cells under the dry condition was reported. These data suggest that cutaneous neuropeptide level is regulated by both psychological and environmental mechanisms. The regulation may cause the downregulation of the threshold of the induction of itch and inflammation. [source] Multiyear to daily radon variability from continuous monitoring at the Amram tunnel, southern IsraelGEOPHYSICAL JOURNAL INTERNATIONAL, Issue 2 2010S. M. Barbosa SUMMARY Radon is a naturally occurring radioactive noble gas generated within mineral grains of uranium bearing rocks by alpha decay from radium. The Amram tunnel (A. Bloch Geophysical Observatory) is a particularly suitable location for the investigation of radon variability. Located in the arid environment of the Arava desert, near Elat, the 170 m tunnel that constitutes the observatory enables radon monitoring in a desert environment and under fairly stable environmental conditions. The analysis of the temporal variability of continuous measurements of radon and environmental parameters at the Amram tunnel over a period of several years shows a complex temporal pattern characterized by non-stationary and multiscale features. Radon concentrations exhibit multiyear variability in the form of a increasing trend of ,1000 Bq m,3 yr,1 in the mean and much larger trends up to ,2500 Bq m,3 yr,1 in the maximum radon levels. Radon concentrations also display strong seasonal patterns, with maxima in summer and minima in winter, ranging from 2.5 kBq m,3 in winter to 35 kBq m,3 in summer. Intraseasonal variability is characterized by very large radon anomalies, with sharp increases of more than 20 kBq m,3 relative to the base level, that occur in spring and summer and last for several days. Daily periodic variability with maxima around midnight appears also in spring and summer, being absent in the cold months. Radon variability at seasonal, intraseasonal and daily timescales is associated with the air temperature outside the tunnel, specifically the temperature gradient between the external environment and the more stable environment inside the tunnel where the measurements are performed. [source] Explaining Australian Economic Success: Good Policy or Good Luck?GOVERNANCE, Issue 2 2006HERMAN SCHWARTZ Australia and some European countries experienced economic "miracles" in the 1990s that reversed prior poor export, employment, and fiscal performance. The miracles might provide transferable lessons about economic governance if it were true that economic governance institutions are malleable, and that actors deliberately changed those institutions in ways that contributed to the miracles. This paper analyzes Australian policy responses to see whether remediation should be attributed to pluck (intentional, strategic remediation of dysfunctional institutions to make them conform with the external environment), luck (environmental change that makes formerly dysfunctional institutions suddenly functional), or just being stuck (endogenous or path-dependent change that brings institutions into conformity with the environment). These distinctions help establish whether actors can consciously engineer institutional change that is "off-path." While pluck appears to explain more than either stuck or luck in the Australian case, the analysis suggests that both off-path behavior and policy transfer are probably rare. [source] Engaging the professional: organising call centre agents in IndiaINDUSTRIAL RELATIONS JOURNAL, Issue 3 2009Ernesto Noronha ABSTRACT The extremely challenging external environment poses numerous challenges to union formation among call centre agents in India. Complicating matters is the acquired professional identity of call centre agents. In this scenario, the union organising call centre employees envisaged that partnership with employers was the only possibility acceptable to call centre agents, employer organisations and society at large, enabling them to regain some acceptability and credibility for the heretofore tainted Indian trade union movement. [source] Intestinal dendritic cells: Their role in bacterial recognition, lymphocyte homing, and intestinal inflammationINFLAMMATORY BOWEL DISEASES, Issue 10 2010S.C. Ng PhD Abstract Dendritic cells (DCs) play a key role in discriminating between commensal microorganisms and potentially harmful pathogens and in maintaining the balance between tolerance and active immunity. The regulatory role of DC is of particular importance in the gut where the immune system lies in intimate contact with the highly antigenic external environment. Intestinal DC constantly survey the luminal microenvironment. They act as sentinels, acquiring antigens in peripheral tissues before migrating to secondary lymphoid organs to activate naive T cells. They are also sensors, responding to a spectrum of environmental cues by extensive differentiation or maturation. Recent studies have begun to elucidate mechanisms for functional specializations of DC in the intestine that may include the involvement of retinoic acid and transforming growth factor-,. Specialized CD103+ intestinal DC can promote the differentiation of Foxp3+ regulatory T cells via a retinoic acid-dependent process. Different DC outcomes are, in part, influenced by their exposure to microbial stimuli. Evidence is also emerging of the close interaction between bacteria, epithelial cells, and DC in the maintenance of intestinal immune homeostasis. Here we review recent advances of functionally specialized intestinal DC and their mechanisms of antigen uptake and recognition. We also discuss the interaction of DC with intestinal microbiota and their ability to orchestrate protective immunity and immune tolerance in the host. Lastly, we describe how DC functions are altered in intestinal inflammation and their emerging potential as a therapeutic target in inflammatory bowel disease. (Inflamm Bowel Dis 2010) [source] The determinants of export performance: A review of the research in the literature between 1998 and 2005INTERNATIONAL JOURNAL OF MANAGEMENT REVIEWS, Issue 4 2008Carlos M.P. Sousa Considerable attention has been paid to the determinants of export performance. However, despite this research effort in identifying and examining the influence of such determinants, the literature is characterized by fragmentation and diversity, hindering theory development and practical advancement in the field. This paper attempts to review and synthesize the knowledge on the subject. As a result, this study reviews and evaluates 52 articles published between 1998 and 2005 to assess the determinants of export performance. The assessment reveals that: (a) more studies have been conducted outside the USA; (b) the majority of the studies focus on manufacturing firms, with relatively few studies examining the service sector; (c) the majority of the export studies continue to focus on small to medium-sized firms; (d) there is a continuous increase in the sample size; (e) despite the problems that may arise from the use of single informants, it seems that none of the studies reviewed here collected data from more than one informant in the firm; (f) an increasing number of studies have been using the export venture as the unit of analysis; (g) the level of statistical sophistication has improved; (h) the use of control and moderating variables in export performance studies has increased; (i) more studies have started to include the external environment in their models, including domestic market characteristics; and (j) market orientation as a key determinant of export performance emerges in this review. Finally, conclusions are drawn, along with some suggestions for further research. [source] Fullerene-Promoted Singlet-Oxygen Photochemical Oxygenations in Glass-Polymer Microstructured ReactorsADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 17 2008Tommaso Carofiglio Abstract In this paper we report the fabrication of thiolene-based microstructured reactors (MRs) that have been specifically designed to include solid-supported reagents within the microchannels network. We propose a convenient solution to realize reversible press-fit, leak-proof interconnects that greatly simplify the MR coupling to the external environment such as capillary tubing, sample reservoirs and pumps. The MRs have been used to carry out the oxidation of ,-terpinene and methionine using [60]fullerene, covalently linked to Tentagel® and silica gel matrices, as a singlet oxygen sensitizer. High conversions have been observed for both substrates although, in the case of ,-terpinene, a partial photodegradation of the endo -peroxide product was detected. Interestingly, in the case of methionine, a quantitative conversion to the corresponding sulfoxides was achieved in about 40 seconds, using low-power, white LED illumination. The reaction time is considerably shorter when compared to the batch procedure that requires, for the same process, about one hour illumination and the use of a 300-W tungsten halogen lamp. [source] Multiple strategies for O2 transport: from simplicity to complexityIUBMB LIFE, Issue 8-9 2007Paolo Ascenzi Abstract O2carriers (extracellular and intracellular as well as monomeric and multimeric) have evolved over the last billion of years, displaying iron and copper reactive centers; very different O2carriers may co-exist in the same organism. Circulating O2carriers, faced to the external environment, are responsible for maintaining an adequate delivery of O2to tissues and organs almost independently of the environmental O2partial pressure. Then, intracellular globins facilitate O2transfer to mitochondria sustaining cellular respiration. Here, molecular aspects of multiple strategies evolved for O2transport and delivery are examined, from the simplest myoglobin to the most complex giant O2carriers and the red blood cell, mostly focusing on the aspects which have been mainly addressed by the so called 'Rome Group'. [source] National and Partisan Contexts of Europeanization: The Case of the French SocialistsJCMS: JOURNAL OF COMMON MARKET STUDIES, Issue 1 2001Alistair Cole This article affirms the usefulness of thinking of Europeanization and European policy change in terms of national, party and European contexts and their interrelationships. Through a case study of the French Socialists in office, the article seeks to establish that national, party and European policy contexts matter in different ways and in varying degrees. National context provides a set of institutions, interests and referential paradigms which help to make sense of a complex external environment. Party provides a distinctive partisan lens and an enduring political community. Europeanization poses a series of direct and indirect policy challenges and opportunities for nation-states and party governments. The article considers national and Europeanized pressures to be more significant than partisan processes. [source] Micro-organisms and dust exposure in an Italian grain millJOURNAL OF APPLIED MICROBIOLOGY, Issue 1 2005C. Dacarro Abstract Aims:, In order to assess possible occupational risk for workers in a grain mill, we evaluated aerial microbiological contamination in different areas of the mill and at different points of the production line. We also measured the concentration of aerodispersed dust particles. Methods and Results:, An assessment of microbiological contamination levels based on a Global Index of Microbial Contamination per cubic metre (GIMC per m3), an Index of Mesophilic Bacterial Contamination, and an Amplification Index is proposed. The indices were obtained from total and fungal counts. The cleaning sector is the most contaminated area of the mill: the mean GIMC per m3 was 17 213·6. In this area, the average microbial contamination was 11·41 times higher than that in the external environment. The highest concentrations of aerodispersed dust (inhalable 2·763 mg m,3; respirable 1·400 mg m,3) were found in the cleaning area. Conclusions:, The proposed microbiological indices and the concentrations of aerodispersed dust particles show that the most hazardous section of the mill is the cleaning area. The large variation in the data does not depend on seasonal factors, but rather on not easily identifiable conditions of the internal environment which facilitate diffusion and/or proliferation of the micro-organisms. Significance and Impact of the Study:, The proposed microbiological contamination indices and the evaluation of the concentration of dust particles allow the identification of critical positions during the production cycle so that suitable measures to prevent the aerial contamination can be taken. [source] Partners in treatment: relational psychoanalysis and harm reduction therapyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 2 2010Debra Rothschild Abstract A relational psychoanalytic harm reduction orientation to the treatment of substance misusers is presented and illustrated with a clinical example. Both harm reduction therapy and relational psychoanalysis rely on a two-person model in which the therapist and client are collaborators in the treatment. In both, substance use is seen in the context of the user's internal psychodynamics and external environment, and there is an emphasis on treating the person as a whole individual whose substance use is one aspect of life, rather than focusing on the substance use itself as was often done in the past. Historically, psychoanalysis and substance abuse treatment were so different from each other that their paths rarely crossed. The introduction of harm reduction therapy to substance abuse and the relational orientation in psychoanalysis have brought the fields closer together such that the valuable contributions that each can make to the other can now be appreciated. © 2010 Wiley Periodicals, Inc.

R. Rodda The oviparous Port Jackson shark Heterodontus portusjacksoni embryo has a long incubation of 10,11 months during which it undergoes major morphological changes. Initially the egg capsule is sealed from the external environment by mucous plugs in either end of the capsule. Four months into incubation, the egg capsule opens to the surrounding sea water. Fifteen stages of development are defined for this species, the first 10 occur within the sealed capsule, the remaining five after capsule opening to hatching. The functional significance of major definitive characters such as circulation within the yolk membrane and embryo, rhythmic lateral movement of the embryo, external gill filaments, heart activity, internal yolk supplies, egg jelly and the significance of the opening of the egg capsule are described. The egg jelly in the sealed capsule functions to mechanically protect the embryo during early development, however, it eventually creates a hypoxic environment to the embryo as the available oxygen is used up. This generates several physiological challenges to the developing embryo. It is able to overcome these problems by morphological changes such as increasing the effective surface area for gaseous exchange with the development of external gill filaments, fins and extensive circulation in both the embryo and attached external yolk sac. These adaptations become limiting as the embryo grows and respiratory needs outweigh the available oxygen. At this time, the mucous plugs dissolve and the capsule becomes open to the external environment. [source] Decision Comprehensiveness and Corporate Entrepreneurship: The Moderating Role of Managerial Uncertainty Preferences and Environmental DynamismJOURNAL OF MANAGEMENT STUDIES, Issue 8 2009Ciaran Heavey abstract Although comprehensiveness is considered among the most salient and enduring strategic decision-making characteristics in organizations, its influence on firm behaviour has remained elusive. As a first step, our study builds and tests a model that specifies the influence of comprehensiveness on the firm's pursuit of corporate entrepreneurship. Our core argument is that while comprehensiveness helps decision-makers gain the knowledge needed to escape the ignorance and overcome doubt associated with this pursuit, this beneficial influence is conditional upon managerial uncertainty preferences, together with the level of dynamism in the external environment. Findings from a large sample study of CEOs from 349 SMEs provide general support for this argument and associated hypotheses. [source] Professional Development of Nursing in Saudi ArabiaJOURNAL OF NURSING SCHOLARSHIP, Issue 3 2001Gail Tumulty Purpose: To describe the development of nursing in Saudi Arabia and to recommend further directions for development of professional nursing in that country. Organizing Construct: A comprehensive needs assessment was performed in 1996 by an onsite consultant to: (a) evaluate the existing nursing system at the ministry, regional, and hospital levels, (b) describe the functional interrelationships of a nursing division within the Ministry of Health, and (c) prepare a work plan outlining the program elements that a nursing division could address to foster high-quality health care in the public sector. Methods: The needs assessment was conducted through direct observation, interviews, and review of existing documents in the Ministry of Health and representative hospitals, health centers, and health institutes. Data were collected about six factors as they pertained to the Ministry of Health Nursing Services: (a) key organizational and managerial activities, (b) the external environment, (c) the social system, (d) employees, (e) nursing services and research, and (f) formal organizational arrangements. Findings and Conclusions: The data showed a young country and an equally young nursing profession struggling to meet the needs of a growing population. The highest priority for the advancement of nursing in Saudi Arabia is the creation of a kingdom-wide system of nurse regulation. Pressing needs include regulation of professional standards, licensure of all nurses practicing in the Kingdom, accreditation of educational programs, and formation of a national nurses association. [source] The influence of top management team attention patterns on global strategic posture of firmsJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 7 2005Orly Levy Drawing upon the managerial cognition and the upper echelons perspectives, this study proposes that the cognitive capabilities of top executives significantly affect globalization efforts. Specifically, the study suggests that managerial attention patterns or the cognitive processes of [noticing and constructing meaning] about the environment influence strategic posture of firms. Based on a longitudinal sample of U.S. firms operating in technologically intensive industries, the results indicate that firms were more likely to develop an expansive global strategic posture when their top management paid attention to the external environment and considered a diverse set of elements in this environment. On the other hand, firms led by top management that paid more attention to the internal environment were less likely to be global. Copyright © 2005 John Wiley & Sons, Ltd. [source] Self-assembly of supramolecular polymers into tunable helical structuresJOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 6 2008Ho-Joong Kim Abstract There is growing interest in the design of synthetic molecules that are able to self-assemble into a polymeric chain with compact helical conformations, which is analogous to the folded state of natural proteins. Herein, we highlight supramolecular approach to the formation of helical architectures and their conformational changes driven by external stimuli. Helical organization in synthetic self-assembling systems can be achieved by the various types of noncovalent interactions, which include hydrogen bonding, solvophobic effects, and metal-ligand interactions. Since the external environment can have a large influence on the strength and configuration of noncovalent interactions between the individual components, stimulus-induced alterations in the intramolecular noncovalent interactions can result in dynamic conformational change of the supramolecular helical structure thus, driving significant changes in the properties of the materials. Therefore, these supramolecular helices hold great promise as stimuli-responsive materials. © 2008 Wiley Periodicals, Inc.

Multinational companies (MNCs) are not only single organisations operating in a global environment, but at the same time they are collections of interlinked subsidiaries that operate in a diversity of national environments. This paper investigates conceptually how subsidiaries of MNCs build relationships with internal MNC counterparts and external market and non-market actors as they mature and build resources and capabilities. It shows that, in order to understand the dynamics of public affairs management in MNCs, we need to study the relationships of MNCs and their subsidiaries with a variety of stakeholders in the internal and external environment of the organisation. Copyright © 2004 Henry Stewart Publications [source] Internationalization, Strategic Behavior, and the Small Firm: A Comparative InvestigationJOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 3 2004Christos Kalantaridis Previous research on the internationalization of the small firm explored the relationship between the adoption of a global orientation and strategic thinking. However, there was difference in opinion between those arguing that there is a positive relationship between the two variables and others who contended that small firms may internationalize by adopting a passive or reactive approach to the external environment. Within this context, this study sets out to further the discussion by comparing the experience of small enterprises with their medium and large-scale counterparts. In doing so, it draws upon the findings of survey of 1,000 internationalized enterprises located in the main urban conurbations of England. The results suggest that overall there is little disparity in strategy development among internationalized enterprises of different sizes. However, whereas the incidence of strategic behavior among medium and large businesses increases with the complexity of international operations, this is not the case for small firms.
