Conformity
Kinds of Conformity Selected AbstractsUsing the Conformity to Masculine Norms Inventory to work with men in a clinical settingJOURNAL OF CLINICAL PSYCHOLOGY, Issue 6 2005James R. Mahalik Given that gender roles are increasingly viewed as salient in clinical work with men, this article describes a process of exploring masculine gender roles with male clients in therapy by using the Conformity to Masculine Norms Inventory (CMNI). Specifically, this article (a) discusses how men's degree of conformity to masculine norms may be connected to a variety of benefits and costs, (b) describes the CMNI as a tool that can be used to explore men's degree of conformity to masculine norms, (c) describes a process by which to use the CMNI to explore the relevance of men's masculine selves to their presenting concerns, and (d) illustrates the process with a case example. As such, the paper is intended to provide a systematic procedure for clinicians working with men who want to explore the benefits and costs that both conformity, and nonconformity, to specific masculinity norms brings for male clients. © 2005 Wiley Periodicals, Inc.

[source] Intermediate Preferences and Behavioral Conformity in Large GamesJOURNAL OF PUBLIC ECONOMIC THEORY, Issue 1 2009GUILHERME CARMONA Motivated by Wooders, Cartwright, and Selten (2006), we consider games with a continuum of players and intermediate preferences. We show that any such game has a Nash equilibrium that induces a partition of the set of attributes into a bounded number of convex sets with the following property: all players with an attribute in the interior of the same element of the partition play the same action. We then use this result to show that all sufficiently large, equicontinuous games with intermediate preferences have an approximate equilibrium with the same property. Our result on behavior conformity for large finite game generalizes Theorem 3 of Wooders et al. (2006) by allowing both a wider class of preferences and a more general attribute space.

Patton The deposition, erosion and deformation of growth strata associated with an actively growing monocline are modelled using mechanically based numerical experiments. The results demonstrate that the nature of the growth-stratal record depends on (1) the interaction between the base-level rate of change and the rate of change of the accommodation space created due to structural relief across the limbs of the monocline; and (2) the progressive folding of the growth strata. With base-level elevation initially coincident with the upper surface of the pre-tectonic units, constant rates of base-level change create three growth-stratal preservation states. If the base level rises, a growth-sediment wedge covers both limbs of the monocline, with thinner sediment thicknesses on the upthrown limb, forming an on-structure wedge. If the base level falls at a rate less than the rate of accommodation space creation due to structural relief, growth-strata pinch out onto the dipping limb of the monocline, forming an off-structure wedge. If the base level falls at a rate greater than the rate of accommodation space generation due to structural relief, no syntectonic deposition occurs and pre-tectonic units on both sides of the monocline are eroded. Syntectonic unconformities develop within the growth-sediment packages when the rate of accommodation space generation changes during the course of the experiment. The bedding angularity across the unconformities is greatest in the region of the dipping limb of the monocline; off structure, the bedding across the correlative event becomes parallel, forming correlative conformities or disconformities. [source] Patterns of Compliance with the German Corporate Governance CodeCORPORATE GOVERNANCE, Issue 4 2008Till Talaulicar ABSTRACT Manuscript Type: Empirical Research Question/Issue: This study investigates whether the form of compliance with the recommendations of the German Corporate Governance Code (GCGC) appears to be idiosyncratic to a specific company or features similarities across firms. The major aim of this research is thus to explore the ability of a classification of compliance patterns to account for the similarities and differences between firms regarding their conformity with the GCGC. Research Findings/Insights: Based on seven dimensions of code compliance, cluster analysis is used to identify discrete groups of companies with similar patterns of code observance. We determine eight patterns of compliance which are characterized by distinct forms of code conformity. Theoretical Academic Implications: The identified cluster solution does not merely reflect the number of rejected code recommendations. Rather, companies with very similar rates of overall compliance with the GCGC are assigned to different clusters because they feature, at the same time, different patterns of code conformity. These findings imply that governance prediction and governance performance studies have to overcome overly aggregated measures of code compliance which only incorporate the number of rejected code recommendations. Practitioner/Policy Implications: This study provides evidence to practitioners and policy makers that firms can be classified regarding their compliance with the code recommendations. In-depth analyses of the identified patterns of compliance furthermore reveal that some patterns may indicate less well substantiated deviations from the code and partly even decouplings of the declared compliance practices. [source] Purity, Soul Food, and Sunni Islam: Explorations at the Intersection of Consumption and ResistanceCULTURAL ANTHROPOLOGY, Issue 2 2004Carolyn Rouse ABSTRACT Contemporary African American followers of Sunni Islam are self-consciously articulating a form of eating that they see as liberating them from the heritage of slavery, while also bringing them into conformity with Islamic notions of purity. In so doing, they participate in arguments about the meaning of "soul food," the relation between "Western" materialism and "Eastern" spirituality, and bodily health and its relation to mental liberation. Debates within the African American Muslim community show us how an older anthropological concern with food taboos can be opened up to history and to the experience of the past reinterpreted in terms of the struggles of the present. [source] Post-conflict Statebuilding and State Legitimacy: From Negative to Positive Peace?DEVELOPMENT AND CHANGE, Issue 4 2008David Roberts ABSTRACT This article is concerned with the potential that statebuilding interventions have to institutionalize social justice, in addition to their more immediate ,negative' peace mandates, and the impact this might have, both on local state legitimacy and the character of the ,peace' that might follow. Much recent scholarship has stressed the legitimacy of a state's behaviour in relation to conformity to global governance norms or democratic ,best practice'. Less evident is a discussion of the extent to which post-conflict polities are able to engender the societal legitimacy central to political stability. As long as this level of legitimacy is absent (and it is hard to generate), civil society is likely to remain distant from the state, and peace and stability may remain elusive. A solution to this may be to apply existing international legislation centred in the UN and the ILO to compel international organizations and national states to deliver basic needs security through their institutions. This has the effect of stimulating local-level state legitimacy while simultaneously formalizing social justice and positive peacebuilding. [source] Non-linearities, Business Cycles and Exchange RatesECONOMIC NOTES, Issue 3 2008Menzie D. Chinn This paper conjoins the disparate empirical literatures on exchange rate models and monetary policy models, with special reference to the importance of output, inflation gaps and exchange rate targets. It focuses in on the dollar/euro exchange rate, and the differential results arising from using alternative measures of the output gap for the US and for the Euro area. A comparison of ,in-sample' prediction against alternative models of exchange rates is also conducted. In addition to predictive power, I also assess the various models' plausibility as economic explanations for exchange rate movements, based on the conformity of coefficient estimates with priors. Taylor rule fundamentals appear to do as well, or better, than other models at the 1-year horizon. [source] Applying species-sensitivity distributions in ecological risk assessment: Assumptions of distribution type and sufficient numbers of species,ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 2 2000Michael C. Newman Abstract Species-sensitivity distribution methods assemble single-species toxicity data to predict hazardous concentrations (HCps) affecting a certain percentage (p) of species in a community. The fit of the lognormal model and required number of individual species values were evaluated with 30 published data sets. The increasingly common assumption that a lognormal model best fits these data was not supported. Fifteen data sets failed a formal test of conformity to a lognormal distribution; other distributions often provided better fit to the data than the lognormal distribution. An alternate bootstrap method provided accurate estimates of HCp without the assumption of a specific distribution. Approximate sample sizes producing HC5 estimates with minimal variance ranged from 15 to 55, and had a median of 30 species-sensitivity values. These sample sizes are higher than those suggested in recent regulatory documents. A bootstrap method is recommended that predicts with 95% confidence the concentration affecting 5% or fewer species. [source] Inter- and intrapersonal processes underlying authoritarianism: The role of social conformity and personal need for structureEUROPEAN JOURNAL OF PERSONALITY, Issue 7 2009Philipp Jugert Abstract Several personality constructs have been theorised to underlie right-wing authoritarianism (RWA). In samples from New Zealand and Germany (Ns,=,218, 259), we tested whether these constructs can account for specific variance in RWA. In both samples, social conformity and personal need for structure were independent predictors of RWA. In Sample 2, where also openness to experience was measured, social conformity and personal need for structure fully mediated the impact of the higher-order factor of openness on RWA. Our results contribute to the integration of current approaches to the personality basis of authoritarianism and suggest that two distinct personality processes contribute to RWA: An interpersonal process related to social conformity and an intrapersonal process related to rigid cognitive style.

[source] Differentiation between and within groups: the influence of individualist and collectivist group normsEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 6 2006Jolanda Jetten The power of individualist and collectivist group norms to influence intergroup and inter-individual differentiation was examined in three studies. Study 1 revealed that intergroup differentiation was lower when group norms prescribed individualism than when they prescribed collectivism. However, inter-individual differentiation was higher when group norms endorsed individualism than when they promoted collectivism. In Studies 2 and 3 we found evidence for the moderating effect of group salience on the relationship between norms and differentiation. Specifically, the effect that individualist group norms reduced intergroup differentiation but enhanced inter-individual differentiation was more pronounced when group salience was high rather than low. This finding demonstrates that conformity to a group norm prescribing individualism influences the manner in which positive differentiation is expressed. The discussion focuses on the caveats of introducing individualist group norms when attempting to reduce intergroup differentiation. Copyright © 2006 John Wiley & Sons, Ltd. [source] Automatic effects of deviancy cues on creative cognitionEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 3 2005Jens Förster Three experiments test the existence of an automatic deviancy-creativity link. Using a lexical decision task, in Experiment 1 we found a semantic link between deviancy and creativity words in that decision times for creativity-related words were enhanced after subliminal deviancy priming. In Experiment 2, participants were led to think about either a punk or an engineer and afterwards were administered creative insight and analytical reasoning problems. According to a pretest, punks and engineers were judged as differing in uniqueness but not in creativity. Participants given ,punk' priming solved more creative insight problems and fewer analytical reasoning problems than those given ,engineer' priming. In Experiment 3, participants were incidentally exposed to abstract artworks symbolically expressing either the concept of conformity or deviancy and were subsequently asked to solve a creative generation task. Exposure to the artwork representing deviancy led to generation of more creative solutions than exposure to that representing conformity. Copyright © 2005 John Wiley & Sons, Ltd. [source] Perceiving ingroup members who use stereotypes: implicit conformity and similarityEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 2 2003Luigi Castelli Previous studies have shown that people subtly conform more to ingroup members who use stereotype-consistent rather than stereotype-inconsistent information when describing an outgroup member (Castelli, Vanzetto, Sherman, & Arcuri, 2001). In the present article, we will address two important issues. First, we will examine whether this subtle conformity toward stereotypers is related to individuals' prejudice level (Study 1). Second, we will examine one of the processes that underlie the perception of ingroup members who use stereotype-consistent information, hypothesizing that individuals implicitly feel more similar to such sources than to ingroup members who use stereotype-inconsistent information (Study 2). Both hypotheses were confirmed and results are discussed in terms of the distinction between implicit and explicit attitudes and their implications in the maintenance of social stereotypes.

[source] ,We're all individuals': group norms of individualism and collectivism, levels of identification and identity threatEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 2 2002Jolanda Jetten Three studies were conducted to investigate the power of group norms of individualism and collectivism to guide self-definition and group behavior for people with low and high levels of group identification. Study 1 demonstrates that in an individualist culture (North America), those who identify highly with their national identity are more individualist than low identifiers. In contrast, in a collectivist culture (Indonesia) high identifiers are less individualist than low identifiers. Study 2 manipulates group norms of individualism and collectivism, and shows a similar pattern on a self-stereotyping measure: High identifiers are more likely to incorporate salient group norms prescribing individualism or collectivism into their self-concept than low identifiers. Study 3 replicates this effect and shows that high identifiers conform more strongly to group norms, and self-stereotype themselves in line with the salient norm than low identifiers when their group is threatened. Hence, the findings suggest that when there is a group norm of individualism, high identifiers may show individualist behavior as a result of conformity to salient group norms. Copyright © 2002 John Wiley & Sons, Ltd. [source] Leadership Style and International Norm Violation: The Case of the Iraq WarFOREIGN POLICY ANALYSIS, Issue 1 2007VAUGHN P. SHANNON We examine the topic of decision making and norm violation in international politics. While constructivists emphasize norm conformity due to global social pressures, and realists emphasize the ease of norm violation due to self-interest and the lack of a world enforcer, we argue that these approaches fail to explain variation in normative behavior in foreign policy. We suggest that normative behavior is mitigated importantly by leaders' beliefs and decision-making styles. Leaders who view the international environment in state-centric, Hobbesian terms and are less sensitive to the political context are more likely to violate international norms than leaders who view world politics in more benign terms and are more sensitive to contextual pressures. We test these expectations by correlating key leadership traits of Bush Administration officials with their positions regarding the normatively suspect invasion of Iraq in 2003. The findings suggest that need for power, belief in ability to control events, ingroup bias, and especially distrust may be important predictors of one's willingness to violate international norms. We discuss the implications of our results for the prospect for international society to regulate force, and call for a third wave of constructivism wedded to its ideational ally of political psychology. [source] The Decline of Inner Suburbs: The New Suburban Gothic in the United StatesGEOGRAPHY COMPASS (ELECTRONIC), Issue 3 2007John Rennie Short In this article, we critically examine transformation and decline in US suburbs. We identify four distinct, chronological phases of development: suburban utopias, suburban conformity, suburban diversity, and suburban dichotomy. An element of this new suburban dichotomy is what we term suburban gothic. We theorize that the forces of an aging housing stock, land-use planning, and deindustrialization contribute to the divergent realities of US suburbs. [source] What determines conformity to Bergmann's rule?GLOBAL ECOLOGY, Issue 6 2007Shai Meiri ABSTRACT Aim, Bergmann's rule, the tendency of body size within species in bird and mammal populations to be positively correlated with latitude, is among the best known biogeographical generalizations. The factors behind such clines, however, are not well understood. Here we use a large data base of 79 mammalian carnivore species to examine the factors affecting latitudinal size clines. Location, Worldwide. Methods, We measured the skulls and teeth of carnivores in natural history museums, and calculated the amount of variation in size explained by latitude, supplementing our measurements with published data. We examined the effects of a number of variables on the tendency to show latitudinal clines. Results, We found that geographical range and latitudinal extent are strongly related to size clines. Minimum temperatures across the range, net primary productivity and habitat diversity also have some, albeit much less, influence. Main conclusions, We suggest that species with large geographical ranges are likely to encounter significant heterogeneity in those factors that influence body size, and are thus likely to exhibit size clines. However, the key factors that determine body size may not always operate along a latitudinal (or other geographical) cline, but be spatially linked to patches in the species range. One such important factor is likely to be food availability, which we show is a strong predictor of size in the brown bear (Ursus arctos) but is not associated with a latitudinal cline. We argue that the spatial distribution of key resources within the species range constitutes a significant predictor of carnivore body size. [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] Religion, Power and Parliament: Rothschild and Bradlaugh RevisitedHISTORY, Issue 305 2007DENNIS GRUBE The British parliament in the nineteenth century reflected the increasingly democratic stability of the British state in a century that saw numerous convulsions on the European continent. It embodied the majesty of British law, the idea that all adult males who dwelt in Britain shared the universal rights of a true-born Englishman, including the right to speak on the affairs of the nation. The repeated attempts of the Jewish Baron Lionel de Rothschild and the atheist Charles Bradlaugh to take their seats after having been lawfully elected to parliament showed, however, that barriers remained against those who were in some way considered ,un-British'. The debates that the perseverance of both men engendered inside the parliament reveal how strongly the conservative British establishment clung on to what it considered to be the Protestant national character. To make British laws, one had to be British in more than citizenship. In essence, it was a debate about British national identity in an increasingly ,liberal' world. The eventual inclusion of both Rothschild and Bradlaugh marked a further shift away from religious conformity as a measure of ,Britishness' as the century drew to a close. [source] Experimental Tests of Normative Group Influence and Representation Effects in Computer-Mediated CommunicationHUMAN COMMUNICATION RESEARCH, Issue 3 2002When Interacting Via Computers Differs From Interacting With Computers Two experiments addressed the questions of if and how normative social influence operates in anonymous computer-mediated communication (CMC) and human-computer interaction (HCI). In Experiment 1, a 2 (public response vs. private response) × 2 (one interactant vs. four interactants) × 3 (textbox vs. stick figure vs. animated character) mixed-design experiment (N = 72), we investigated how conformity pressure operates in a simulated CMC setting. Each participant was asked to make a decision in hypothetical social dilemmas after being presented with a unanimous opinion by other (ostensible) participants. The experiment examined how the visual representation of interaction partners on the screen moderates this social influence process. Group conformity effects were shown to be more salient when the participant's responses were allegedly seen by others, compared to when the responses were given in private. In addition, participants attributed greater competence, social attractiveness, and trustworthiness to partners represented by anthropomorphic characters than those represented by textboxes or stick figures. Experiment 2 replicated Experiment 1, replacing interaction with a computer(s) rather than (ostensible) people, to create an interaction setting in which no normative pressure was expected to occur. The perception of interaction partner (human vs. computer) moderated the group conformity effect such that people expressed greater public agreement with human partners than with computers. No such difference was found for the private expression of opinion. As expected, the number of computer agents did not affect participants' opinions whether the responses were given in private or in public, while visual representation had a significant impact on both conformity measures and source perception variables. [source] Propagation of longest-edge mesh patterns in local adaptive refinementINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING, Issue 7 2008J. P. Suárez Abstract We examine the propagation of local adaptive mesh refinement (AMR) under a longest edge conformity scheme. Supporting numerical studies are included and discussed. Of specific interest is the statistical behaviour of the propagation zone in AMR of simplicial meshes. To this end three propagation metrics are used: the total number of original triangles in the propagation paths emanating from any target element, the longest individual edge path, and the extent of secondary refinement due to the conformity.

A simple and efficient approach to ensuring conformity of the approximations across element interfaces is described. Hierarchic bases of arbitrary polynomial order are presented. It is shown how these may be used to construct finite element approximations of arbitrary, non-uniform, local order approximation on unstructured meshes of curvilinear tetrahedral elements.

[source] Intensity-modulated radiotherapy with an integrated boost to the macroscopic tumor volume in the treatment of high-grade gliomasINTERNATIONAL JOURNAL OF CANCER, Issue 6 2001Christoph Thilmann M.D. Abstract Integrated boost radiotherapy (IBRT) delivers a higher fraction size to the gross tumor volume and a conventional fraction size to the surrounding tissue of microscopic spread. We compared stereotactic conformal radiotherapy (SCRT) and intensity-modulated radiotherapy (IMRT) with regard to their suitability for IBRT in the treatment of high-grade gliomas. In 20 patients treated with conventional radiotherapy, an additional treatment plan for IBRT [planning target volume (PTV1) defined as contrast-enhancing lesion plus margin due to setup errors 75 Gy, PTV2 defined as edema plus margin due to microscopic spread and setup error 60 Gy] with 7 non-coplanar beams for IMRT and for SCRT was carried out and compared. The part of the PTV2 irradiated with more than 107% of the prescribed dose was 13.9% for IMRT and 30.9% for SCRT (P < 0.001). Dose coverage of PTV2 (volume above 95% of the prescribed dose) was improved with IMRT (88.4% vs. 75.3% with SCRT, P < 0.001). Dose coverage of PTV1 was slightly higher with SCRT (93.7% vs. 87.5% with IMRT), but the conformity to the boost shape was improved by IMRT [conformity index (COIN95) = 0.85 vs. 0.69 with SCRT]. Simultaneously the brain volume irradiated with > 50 Gy was reduced from 60 to 33 cc (P < 0.001). We conclude that IMRT is suitable for local dose escalation in the enhancing lesion and for delivering a homogeneous dose to the PTV2 outside the PTV1 at the same time. Our encouraging results justify application of IMRT for IBRT in the treatment of high-grade gliomas. For clinical evaluation a phase III study has been initiated. © 2001 Wiley-Liss, Inc. [source] Oxidation of substituted benzaldehydes by quinolinium chlorochromate: A structure and solvent dependent kinetic studyINTERNATIONAL JOURNAL OF CHEMICAL KINETICS, Issue 4 2003G. Fatima Jeyanthi The kinetics of oxidation of several para-substituted benzaldehydes by quinolinium chlorochromate was studied under pseudo-first-order conditions in different (hydrogen bond donor and hydrogen bond acceptor) neat organic solvents. The operation of nonspecific and specific solvent,solvent,solute interactions was explored by correlating the rate data with solvent parameters through correlation analysis. Both electron-releasing and electron-withdrawing substituents enhanced the rate and the Hammett plot showed a break in the reactivity order indicating applicability of dual mechanism. An explanation in conformity with structure and solvent effects on reactivity has been proposed. © 2003 Wiley Periodicals, Inc.

The mechanical effect applied to the laundry in the household washers was not obtained in the LOM by increasing mechanical impact or the number of metal balls. Extended washing time did not improve removal of blood soil in the LOM, although it did increase removal of mayonnaise soil containing chlorophyll. However, in practice a washing time of 60,85 min is relatively long for a laboratory device considering the claimed time-saving nature of these devices. None of the examined parameters affected removal of a red wine soil containing tannins, which was poor in all test combinations both in the household machines and in the laboratory washing machine. Bleaching agent is recommended for removal of this type of soil. In conclusion, conformity between washing results of the laboratory washing machine and the drum-type household washing machines depends on the type of soiled test fabrics and other parameters in the washing process. Removal of blood soil differed most between the household machines and the LOM. [source] Refrigerated transport and environmentINTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 10 2004S. K. Chatzidakis Abstract The regulations and the technical specifications for international carriage of perishable foodstuffs and for the special equipment to be used for such carriage are prescribed in the international ATP Agreement. The refrigerated special equipment has to be checked for quality conformity with the ATP standards, at officially designated national ATP test stations. Some of the alternatively proposed ATP testing procedures for checking of the in-service and second-hand refrigerated transport equipment are incomplete and can give incorrect test results. The consequence is increase in energy consumption and an increased environmental pollution through CO2 emission. This study analyses the ATP testing procedures for in-service equipment, investigates the impact on the environmental and gives some proposals for improvement.

[source] Using a neural network in the software testing processINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 1 2002Meenakshi Vanmali Software testing forms an integral part of the software development life cycle. Since the objective of testing is to ensure the conformity of an application to its specification, a test "oracle" is needed to determine whether a given test case exposes a fault or not. Using an automated oracle to support the activities of human testers can reduce the actual cost of the testing process and the related maintenance costs. In this paper, we present a new concept of using an artificial neural network as an automated oracle for a tested software system. A neural network is trained by the backpropagation algorithm on a set of test cases applied to the original version of the system. The network training is based on the "black-box" approach, since only inputs and outputs of the system are presented to the algorithm. The trained network can be used as an artificial oracle for evaluating the correctness of the output produced by new and possibly faulty versions of the software. We present experimental results of using a two-layer neural network to detect faults within mutated code of a small credit approval application. The results appear to be promising for a wide range of injected faults. ? 2002 John Wiley & Sons, Inc. [source] Evaluating five dedicated automatic devices for haemoglobinopathy diagnostics in multi-ethnic populationsINTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 5 2009P. VAN DELFT Summary We have tested five haemoglobin (Hb) separation apparatuses, dedicated to haemoglobinopathy diagnostics. These are the four high performance liquid chromatography devices: VARIANT IIÔ, HA 8160, G7, Ultra2 and the Capillary Electrophoresis apparatus from Sebia. In the first place, we focussed on the capacity of all apparatuses to detect the most common structural variants relevant for public health, these being HbS, HbC, HbE, HbD-Punjab and HbO-Arab. We then compared how the high HbA2,-thalassaemia carriers were identified. All apparatuses were able to identify carriers of these traits with the expected sensitivity and specificity. With the primary goal of a high degree of conformity in basic diagnostics of haemoglobinopathies, we present the interpretation and the significance of the results on all apparatuses, and we comment on the unavoidable problems and solutions. [source] Promoting acute thrombolysis for ischaemic stroke (PRACTISE)INTERNATIONAL JOURNAL OF STROKE, Issue 2 2007Protocol for a cluster randomised controlled trial to assess the effect of implementation strategies on the rate, effects of thrombolysis for acute ischaemic stroke (ISRCTN 20405426) Rationale Thrombolysis with intravenous rtPA is an effective treatment for patients with ischaemic stroke if given within 3 h from onset. Generally, more than 20% of stroke patients arrive in time to be treated with thrombolysis. Nevertheless, in most hospitals, only 1,8% of all stroke patients are actually treated. Interorganisational, intraorganisational, medical and psychological barriers are hampering broad implementation of thrombolysis for acute ischaemic stroke. Aims To evaluate the effect of a high-intensity implementation strategy for intravenous thrombolysis in acute ischaemic stroke, compared with regular implementation; to identify success factors and obstacles for implementation and to assess its cost-effectiveness, taking into account the costs of implementation. Design The PRACTISE study is a national cluster-randomised-controlled trial. Twelve hospitals have been assigned to the regular or high-intensity intervention by random allocation after pair-wise matching. The high-intensity implementation consists of training sessions in conformity with the Breakthrough model, and a tool kit. All patients who are admitted with acute stroke and onset of symptoms not longer than 24 h are registered. Study outcomes The primary outcome measure is treatment with thrombolysis. Secondary outcomes are admission within 4 h after onset of symptoms, death or disability at 3 months, the rate of haemorrhagic complications in patients treated with thrombolysis, and costs of implementation and stroke care in the acute setting. Tertiary outcomes are derived from detailed criteria for the organisational characteristics, such as door-to-needle time and protocol violations. These can be used to monitor the implementation process and study the effectiveness of specific interventions. Discussion This study will provide important information on the effectiveness and cost-effectiveness of actively implementing an established treatment for acute ischaemic stroke. The multifaceted aspect of the intervention will make it difficult to attribute a difference in the primary outcome measure to a specific aspect of the intervention. However, careful monitoring of intermediate parameters as well as monitoring of accomplished SMART tasks can be expected to provide useful insights into the nature and role of factors associated with implementation of thrombolysis for acute ischaemic stroke, and of effective acute interventions in general. [source] Mechanisms for intergovernmental relations in federationsINTERNATIONAL SOCIAL SCIENCE JOURNAL, Issue 167 2001Brian R. Opeskin Federations employ a large variety of mechanisms for conducting relations between central, regional, and local levels of government. These mechanisms span the executive, legislative, and judicial branches of government within each level. Executive involvement ranges widely in degree of formality, from the making of formal intergovernmental agreements to informal liaison between governmental officers. Executive mechanisms have also evolved for correcting vertical and horizontal fiscal imbalances in federal systems. Legislatures play an important role in giving the force of law to cooperative policies initiated by the executive. These legislative mechanisms include reciprocal schemes, complementary schemes, mirror legislation, and the reference or delegation of powers from one level of government to another. The judiciary, though often undervalued, is significant for its role in establishing the legal framework within which other branches of government conduct their intergovernmental relations, through articulation of powers and competencies. The article concludes that policy makers should exercise care in selecting mechanisms that are appropriate to their task. In particular, regard should be had to the efficiency of each mechanism, and its conformity with federal values and the rule of law. [source] | ||||||||||||||||||||||||||||||||||||||||||||||||||||
