Selected AbstractsSubnational political opportunity structures and the success of the radical right: Evidence from the March 2004 regional elections in FranceEUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 6 2007ELINA KESTILÄ The concept of ,political opportunity structure' refers to the degree of openness of a particular political system and the external institutional or socio-economic constraints and opportunities that it sets for political parties. Comparative analysis across subnational units is conducted where the 94 departments of mainland France are the units of analysis. The significance of electoral institutions (district magnitude), party competition (effective number of parties), electoral behaviour (turnout) and socioeconomic conditions (immigration and unemployment) on the ability of the FN to gather votes across the departments is assessed by means of multiple regression. The empirical results show that the subnational political opportunity structures have been of great importance for the FN. Some four out of the five independent variables are statistically significant and explain a great deal of the variance in the two dependent variables (electoral support for FN list and index of electoral success). Turnout and district magnitude are negatively correlated with the electoral fortunes of the FN, while unemployment and the effective number of party lists are positively correlated with the success of the FN in the regional elections. The variable that indicates the share of non-European immigrants does not provide additional explanatory power in a statistically significant way. [source] LINEAGES WITH LONG DURATIONS ARE OLD AND MORPHOLOGICALLY AVERAGE: AN ANALYSIS USING MULTIPLE DATASETSEVOLUTION, Issue 4 2007Lee Hsiang Liow Lineage persistence is as central to biology as evolutionary change. Important questions regarding persistence include: why do some lineages outlive their relatives, neither becoming extinct nor evolving into separate lineages? Do these long-duration lineages have distinctive ecological or morphological traits that correlate with their geologic durations and potentially aid their survival? In this paper, I test the hypothesis that lineages (species and higher taxa) with longer geologic durations have morphologies that are more average than expected by chance alone. I evaluate this hypothesis for both individual lineages with longer durations and groups of lineages with longer durations, using more than 60 published datasets of animals with adequate fossil records. Analyses presented here show that groups of lineages with longer durations fall empirically into one of three theoretically possible scenarios, namely: (1) the morphology of groups of longer duration lineages is closer to the grand average of their inclusive group, that is, their relative morphological distance is smaller than expected by chance alone, when compared with rarified samples of their shorter duration relatives (a negative group morpho-duration distribution); (2) the relative morphological distance of groups of longer duration lineages is no different from rarified samples of their shorter duration relatives (a null group morpho-duration distribution); and (3) the relative morphological distance of groups of longer duration lineages is greater than expected when compared with rarified samples of their shorter duration relatives (a positive group morpho-duration distribution). Datasets exhibiting negative group morpho-duration distributions predominate. However, lineages with higher ranks in the Linnean hierarchy demonstrate positive morpho-duration distributions more frequently. The relative morphological distance of individual longer duration lineages is no different from that of rarified samples of their shorter duration relatives (a null individual morpho-duration distribution) for the majority of datasets studied. Contrary to the common idea that very persistent lineages are special or unique in some significant way, both the results from analyses of long-duration lineages as groups and individuals show that they are morphologically average. Persistent lineages often arise early in a group's history, even though there is no prior expectation for this tendency in datasets of extinct groups. The implications of these results for diversification histories and niche preemption are discussed. [source] Anticipating Tax Changes: Evidence from the Finnish Corporate Income Tax Reform of 2005,FISCAL STUDIES, Issue 2 2008Seppo Kari H25; H32 Abstract Using register-based panel data covering all Finnish firms from 1999 to 2004, we examine how corporations anticipated the 2005 dividend tax increase via changes in their dividend and investment policies. The Finnish capital and corporate income tax reform of 2005 creates a useful opportunity to measure this behaviour, since it involves exogenous variation in the tax treatment of different types of firms. The estimation results reveal that those firms that anticipated a dividend tax hike increased their dividend payouts in a statistically significant way. This increase was not accompanied by a reduction in investment activities, but rather was associated with increased indebtedness in non-listed firms. The results also suggest that the timing of dividend distributions probably offsets much of the potential for increased dividend tax revenue following the reform. [source] Innovation and Regional Growth in the Enlarged Europe: The Role of Local Innovative Capabilities, Peripherality, and EducationGROWTH AND CHANGE, Issue 4 2005RICCARDO CRESCENZI ABSTRACT In this paper, a formal model for the relationship between innovation and growth in European Union regions is developed drawing upon the theoretical contribution of the systems of innovation approach. The model combines the analytical approach of the regional growth models with the insights of the systemic approach. The cross-sectional analysis, covering all the Enlarged Europe (EU-25) regions (for which data are available), shows that regional innovative activities (for which a specific measure is developed) play a significant role in determining differential regional growth patterns. Furthermore, the model sheds light on how geographical accessibility and human capital accumulation, by shaping the regional system of innovation, interact (in a statistically significant way) with local innovative activities, thus allowing them to be more (or less) effectively translated into economic growth. The paper shows that an increase in innovative effort is not necessarily likely to produce the same effect in all EU-25 regions. Indeed, the empirical analysis suggests that in order to allow innovative efforts in peripheral regions to be as productive as in core areas, they need to be complemented by huge investments in human capital. [source] Human genome variation and pharmacogenetics,HUMAN MUTATION, Issue 4 2008Bruce Gottlieb Abstract A recent HGVS-sponsored symposium has examined, for the first time, the possible effects of the discovery of very large and widespread amounts of human genome variation on the emerging fields of pharmacogenetics and pharmacogenomics. This article discusses the effects of the resultant paradigm shifts and raises a number of important questions that need to be considered in order to truly advance the field in a meaningful and significant way.

[source] Cultural Districts, Property Rights and Sustainable Economic GrowthINTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 1 2002Walter Santagata The purpose of this article is to analyse the economic properties as well as the institutions governing the start-up and evolution of cultural districts. The first part of the article reviews the relationships between culture, viewed as an idiosyncratic good, and the theory of industrial districts. The second part comprises a critical discussion of four models of cultural districts: the industrial cultural district (mainly based on positive externalities, localized culture and traditions in ,arts and crafts'); the institutional cultural district (chiefly relying on the assignment of property rights); the museums cultural district (based on network externalities and the search for optimal size); and the metropolitan cultural district (based on communication technologies, performing arts and electronic trade). The assignment of intellectual property rights to local idiosyncratic cultural goods seems to be the most significant way to differentiate among cultural districts. The final section discusses a possible convergence of all district models towards the institutional district, based on the creation of a system of property rights as a means to protect localized production. Cet article tente d'analyser les propriétés économiques et les institutions qui régissent la création et l'évolution de districts culturels. La première partie étudie les relations entre la culture , vue comme un bien idiosyncrasique , et la théorie des districts industriels. La deuxième partie est un débat critique sur quatre modèles de districts culturels: le district culturel industriel (basé essentiellement sur des externalités positives, des cultures et traditions artisanales locales), le district culturel institutionnel (s'appuyant principalement sur l'attribution de droits de propriété), le district culturel des musées (fondé sur des effets d'entraînement en réseau et la recherche d'une taille optimale), et le district culturel métropolitain (basé sur les technologies de communication, des représentations artistiques et le commerce électronique). L'attribution de droits de propriété intellectuelle sur des biens culturels idiosyncrasiques locaux semble être la meilleure manière de différencier les districts culturels. La dernière partie de l'article examine une convergence possible de tous les modèles de district vers le district institutionnel, en s'appuyant sur la création d'un système de droits de propriété comme moyen de protection d'une production locale. [source] Influence of the length of the plasticating system on selected characteristics of an autothermal extrusion processADVANCES IN POLYMER TECHNOLOGY, Issue 1 2005Janusz W. Sikora Abstract The presented paper aims to determine the influence of the length of the plasticating system on the course of an autothermal extrusion process. Three special screws were used, of the relationship of the length of the operating part to diameter of the screw L/D = 20, 25, and 30, with a tip for intensive shearing and mixing, assigned for polyethylene processing, and five screw rotation frequencies were applied. The conducted research consisted of the measurement, during the extrusion, of the factors studied directly and in the calculation, and on their basis, the values characterizing this process. It is stated that the change of the length of the plasticating system in a significant way influences the dependences determining polymer flow rate, temperature and pressure of the processed polymer, extrusion velocity, specific energy consumption, and energy efficiency of the extruder; that is, the whole characteristic of an autothermal extrusion process. © 2005 Wiley Periodicals, Inc.

Straetmans We apply extreme value analysis to US sectoral stock indices in order to assess whether tail risk measures like value-at-risk and extremal linkages were significantly altered by 9/11. We test whether semi-parametric quantile estimates of ,downside risk' and ,upward potential' have increased after 9/11. The same methodology allows one to estimate probabilities of joint booms and busts for pairs of sectoral indices or for a sectoral index and a market portfolio. The latter probabilities measure the sectoral response to macro shocks during periods of financial stress (so-called ,tail-,s'). Taking 9/11 as the sample midpoint we find that tail-,s often increase in a statistically and economically significant way. This might be due to perceived risk of new terrorist attacks.

[source] Speech Watermarking: An Approach for the Forensic Analysis of Digital Telephonic Recordings,JOURNAL OF FORENSIC SCIENCES, Issue 4 2010Marcos Faundez-Zanuy Ph.D Abstract:, In this article, the authors discuss the problem of forensic authentication of digital audio recordings. Although forensic audio has been addressed in several articles, the existing approaches are focused on analog magnetic recordings, which are less prevalent because of the large amount of digital recorders available on the market (optical, solid state, hard disks, etc.). An approach based on digital signal processing that consists of spread spectrum techniques for speech watermarking is presented. This approach presents the advantage that the authentication is based on the signal itself rather than the recording format. Thus, it is valid for usual recording devices in police-controlled telephone intercepts. In addition, our proposal allows for the introduction of relevant information such as the recording date and time and all the relevant data (this is not always possible with classical systems). Our experimental results reveal that the speech watermarking procedure does not interfere in a significant way with the posterior forensic speaker identification. [source] Nitric Oxide Mediates Inhibitory Effect of Interleukin-1, on Estrogen Production in Human Granulosa-Luteal CellsJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2001Hisako Tobai Abstract Objective: To investigate the effect of IL-1, on NO production and steroidogenesis in human granulosa-luteal cells obtained from women undergoing in vitro fertilization procedures. Subjects and Methods:To investigate the effect of IL-1,, granulosa-luteal cells were cultured with various doses of IL-1, (0, 0.05, 0.5, 5, 50, 100 ng/ml), IL-1, (5 ng/ml) with NG -nitro-L-arginine-methyl ester (l-NAME), selective inhibitors of NOS, sodium nitroprusside (SNP), NO donors and Genistain, a tyrosine kinase inhibitor. Results:IL-1, induced a dose-dependent stimulation of NO production and inhibited the production of estradiol in a significant way in a dose-dependent manner. l-NAME significantly decreased NO production and increased the production of estradiol and progesterone. SNP significantly increased NO production and caused decreases in the production of both estradiol and progesterone. Genistain decreased NO production and significantly increased the production of estradiol and progesterone. Inducible NOS (iNOS) messenger RNA was present in granulosa-luteal cells before treatment with IL-1,. Conclusions:IL-1, stimulated NO production, and NO inhibited the production of estradiol. [source] Effect of Er:YAG and Diode lasers on the adhesion of blood components and on the morphology of irradiated root surfacesJOURNAL OF PERIODONTAL RESEARCH, Issue 5 2006Letícia Helena Theodoro Objective:, The aim of this study was to evaluate in vitro, by scanning electron microscopy (SEM), the adhesion of blood components on root surfaces irradiated with Er:YAG (2.94 µm) and GaAlAs Diode (808 nm) lasers and the effects on the morphology of irradiated root surfaces. Methods:, One hundred samples of human teeth were obtained. They were previously planed and scaled with manual instruments and divided into five groups of 20 samples each: G1 (control group) , absence of treatment; G2 , Er:YAG laser (7.6 J/cm2); G3 , Er:YAG laser (12.9 J/cm2); G4 , Diode laser (90 J/cm2) and G5 , Diode laser (108 J/cm2). After these treatments, 10 samples of each group received a blood tissue but the remaining 10 did not. After laboratory treatments, the samples were obtained by SEM, the photomicrographs were analysed by the score of adhesion of blood components and the results were statistically analysed (Kruskall,Wallis and Mann,Whitney test). Results:, In relation to the adhesion of blood components, the study showed no significant differences between the control group and the groups treated with Er:YAG laser (p = 0.9633 and 0.6229). Diode laser radiation was less effective than control group and Er:YAG laser radiation (p < 0.01). Conclusions:, None of the proposed treatments increased the adhesion of blood components in a significant way when compared to the control group. Although the Er:YAG laser did not interfere in the adhesion of blood components, it caused more changes on the root surface, whereas the Diode laser inhibited the adhesion. [source] Development of a robust once-a-day glipizide matrix systemJOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 6 2007Shahla Jamzad The robustness of a new hydroxypropylmethylcellulose (HPMC) based modified release glipizide (10 mg) formulation was studied. The tablet formulations were prepared by dry blending the ingredients and direct compression, incorporating a range of release modifying agents up to ± 20% w/w relative to an optimized formulation. The dissolution was assessed in 900 mL pH 6.8 buffer at 75 rev min,1 paddle speed. Calculated difference and similarity factors (f1 and f2) and results of analysis of variance suggest that the overall release profiles were similar. Compositional changes up to ± 20% w/w and a reduction of drug dose to half did not change the general release pattern of this low dose/pH-dependent drug in a significant way. It is concluded that the drug release from the developed matrix systems is highly dependent on the kinetics of hydration and erosion, and that the proposed compositional changes within ± 20% w/w did not alter this relationship. The particulate systems used were characterized by determining the Carr index, Hausner ratio and the rheological properties using a texture analyser. Results indicate that the release is reproducible and the system has potential for successful scale-up operation, while complying with recommended Food and Drug Administration guidelines "Scale Up and Post Approval Changes". [source] Squamous cell carcinoma of the temporal bone,THE LARYNGOSCOPE, Issue 6 2010Paul W. Gidley MD Abstract Objectives/Hypothesis: To study the survival outcomes of patients with squamous cell carcinoma (SCC) of the temporal bone. A secondary purpose was to evaluate the University of Pittsburgh staging system as a predictor of survival. Study Design: Retrospective review. Methods: We performed a single-institution retrospective review of the medical charts of patients diagnosed with SCC of the temporal bone between 1945 and 2005. We identified the patients' demographic characteristics, presenting symptoms, physical examination findings, tumor histology, disease extent, treatment course, and clinical outcomes. We used the Pittsburgh staging system (2000) to determine the patients' tumor classification and disease state. We then compared the overall and disease-free survival rates between patients with early-stage versus late-stage disease. Results: We identified 124 patients with SCC of the temporal bone. Of these, 71 had incident (untreated) SCC, 26 had recurrent SCC, and 27 had persistent SCC after treatment elsewhere. The 5-year overall survival rate for patients with incident SCC was 38%, and the disease-free survival rate was 60%. The overall survival rate for patients with incident SCC was similar to that for patients with persistent disease and was significantly better than that for patients with recurrent SCC (P = .008). Patients with early-stage tumors (T1 or T2) had longer overall survival than those with late-stage tumors (T3 or T4; P = .004, log-rank). The 5-year overall survival rate was 48% for patients with early-stage disease and 28% for patients with late-stage disease. Furthermore, patients with T1 tumors had significantly longer overall survival than patients with T2 tumors (P = .039) and patients with T3 and T4 tumors (P = .0008). Overall survival (OS) and disease-free interval (DFI) were improved for T2 tumors when radiotherapy was combined with surgery (OS, P = .011; DFI, P = .02). T1 tumors did not benefit in a statistically significant way with combined therapy. T3 and T4 tumors had relatively poor outcomes in spite of combined therapy. Twenty-two patients (31%) experienced a recurrence within 1 year of treatment, whereas only one patient developed recurrence after 1 year. Lymph node metastasis, facial paralysis, or involvement of the carotid artery, jugular foramen, or infratemporal fossa were not significantly associated with overall or disease-free survival. Conclusions: Patients with recurrent SCC of the temporal bone had significantly shorter overall survival and disease-free interval than patients with incident SCC. In addition, patients with early-stage disease (T1 and T2) had significantly longer overall survival and disease-free survival than patients with late-stage tumors. Laryngoscope, 2010 [source] International Promises and Domestic Pragmatism: To What Extent will the Employment Relations Act 1999 Implement International Labour Standards Relating to Freedom of AssociationTHE MODERN LAW REVIEW, Issue 3 2000Tonia Novitz This paper explores the rhetoric and reality surrounding implementation of international labour standards in the Employment Relations Act 1999. It focuses on UK commitments relating to freedom of association and considers whether the new legislation goes any significant way towards their fulfilment. The paper begins by outlining obligations which arise from a state's membership of the International Labour Organisation (ILO) and ratification of ILO Conventions. It then goes on to examine indications that, since the change of government in 1997, there has been a significant shift in UK policy relating to such international obligations. The remainder of the paper examines reforms made by the Employment Relations Act to trade union recognition, protection of strikers from dismissal and prevention of anti-union discrimination. It emerges that the Third Way proposed by the present Labour Government entails a complicated detour from the path of full compliance with ILO standards. [source] The Ecological Future of the North American Bison: Conceiving Long-Term, Large-Scale Conservation of WildlifeCONSERVATION BIOLOGY, Issue 2 2008ERIC W. SANDERSON Bison bison; conservación de especies; Declaración de Vermejo; metas de conservación; representación ecológica Abstract:,Many wide-ranging mammal species have experienced significant declines over the last 200 years; restoring these species will require long-term, large-scale recovery efforts. We highlight 5 attributes of a recent range-wide vision-setting exercise for ecological recovery of the North American bison (Bison bison) that are broadly applicable to other species and restoration targets. The result of the exercise, the "Vermejo Statement" on bison restoration, is explicitly (1) large scale, (2) long term, (3) inclusive, (4) fulfilling of different values, and (5) ambitious. It reads, in part, "Over the next century, the ecological recovery of the North American bison will occur when multiple large herds move freely across extensive landscapes within all major habitats of their historic range, interacting in ecologically significant ways with the fullest possible set of other native species, and inspiring, sustaining and connecting human cultures." We refined the vision into a scorecard that illustrates how individual bison herds can contribute to the vision. We also developed a set of maps and analyzed the current and potential future distributions of bison on the basis of expert assessment. Although more than 500,000 bison exist in North America today, we estimated they occupy <1% of their historical range and in no place express the full range of ecological and social values of previous times. By formulating an inclusive, affirmative, and specific vision through consultation with a wide range of stakeholders, we hope to provide a foundation for conservation of bison, and other wide-ranging species, over the next 100 years. Resumen:,Muchas especies de mamíferos de distribución amplia han experimentado declinaciones significativas durante los últimos 200 años; la restauración de estas especies requerirá esfuerzos de recuperación a largo plazo y a gran escala. Resaltamos 5 atributos de un reciente ejercicio de gran visión para la recuperación ecológica del bisonte de Norte América (Bison bison) que son aplicables en lo general a otras especies y objetivos de restauración. El resultado del ejercicio, la "Declaración de Vermejo", explícitamente es (1) de gran escala, (2) de largo plazo, (3) incluyente, (4) satisfactor de valores diferentes y (5) ambicioso. En parte, establece que "En el próximo siglo, la recuperación ecológica del Bisonte de Norte América ocurrirá cuando múltiples manadas se desplacen libremente en los extensos paisajes de todos los hábitats importantes en su rango de distribución histórica, interactúen de manera significativa ecológicamente con el conjunto más completo de otras especies nativas e inspiren, sostengan y conecten culturas humanas." Refinamos esta visión en una tarjeta de puntuación que ilustra cómo las manadas de bisonte individuales pueden contribuir a la visión. También desarrollamos un conjunto de mapas y analizamos las distribuciones actuales y potencialmente futuras del bisonte con base en la evaluación de expertos. Aunque actualmente existen más de 500,000 bisontes en Norte América, estimamos que ocupan <1% de su distribución histórica y no expresan el rango completo de valores ecológicos y culturales de otros tiempos. Mediante la formulación de una visión incluyente, afirmativa y específica basada en la consulta a una amplia gama de interesados, esperamos proporcionar un fundamento para la conservación del bisonte, y otras especies de distribución amplia, para los próximos 100 años.

Through the interactions between its various versions, The Malcontent charts the linguistic, stylistic, and cultural boundaries of early modern wit as both intrinsic class marker and promiscuous commodity. This duality of wit helps the play negotiate the complexities of its own theatrical genealogy that not only inform the larger context of wit in the period, but also inflect, in significant ways, the play's modern reception. (I.M.) [source] Using Websites to Disseminate Research on Urban SpatialitiesGEOGRAPHY COMPASS (ELECTRONIC), Issue 6 2009Gillian Rose This paper reviews a selection of websites that explore urban geographies. Many sites use the web as a depository for large amounts of research data. However, many are using websites to disseminate research findings, and the paper focuses on these. It suggests that, thus far, there are three significant ways in which urban researchers are exploiting the potentialities of web technologies to interpret urban spaces: by evoking a sense of the complexity of urban spatialities; by inviting site visitors to engage actively and performatively with the research materials; and by emphasising the sensory qualities of urban spaces. The paper discusses how one website in particular invites its visitors to engage with complex, sensory urban spatialities. The paper compares geographers' use of collage and montage as part of this discussion, and ends by reflecting on current work and commenting on its future development. [source] Disruptive information system innovation: the case of internet computingINFORMATION SYSTEMS JOURNAL, Issue 4 2003Kalle Lyytinen Abstract., Information system (IS) innovation can be defined as a novel organizational application of digital computer and information communication technologies (ICT). This paper discusses how modalities of applying ICT technologies in their form and scope exhibit radical breaks, which are introduced herein as ,disruptive IS innovations'. This notion of disruptive IS innovation is developed by drawing upon and extending Swanson's (1994) theory of IS innovation as well as the concept of radical innovation. Disruptive innovations strongly influence the future trajectory of the adoption and use of ICT in organizational contexts and make the trajectory deviate from its expected course. In doing so, these disruptive innovations distinctly define what an IS is and how it is deployed in order to address current and future organizational and managerial prerogatives. Such changes are triggered breakthroughs in the capability of ICT that lead to the revision and expansion of associated cognitive models (frames) of computing. Disruptive IS innovations are those that lead to changes in the application of ICT that are both pervasive and radical. The pervasive nature implies that innovative activity spans all innovation subsets of the quad-core model of IS innovation introduced herein. Innovation types include: IS use and development processes; application architecture and capability; and base technologies. Radical in nature, disruptive is innovations depart in significant ways from existing alternatives and lead to deviation from expected use and diffusion trajectory. This paper demonstrates the importance of a concept of disruptive IS innovation by investigating how changes triggered by internet computing (Lyytinen et al., 1998) meet the conditions of a disruptive IS innovation defined herein. The analysis also affirms both the pervasive and radical nature of internet computing and explains how internet computing has fundamentally transformed the application portfolio, development practices and IS services over time. The analysis demonstrates that, with the concept of disruptive IS innovation, we can fruitfully analyse ,long' waves of ICT evolution , an issue that has largely been overlooked in the IS community. On a theoretical plane, the paper advocates the view that we need to look beyond linear, unidirectional, and atomistic concepts of the diffusion of IS innovations where innovative activity takes places in a linear fashion by oscillating between small technological innovations and small organizational innovations. In contrast, IS innovation can exhibit fundamental discontinuity; we need to theoretically grasp such disruptive moments. The recent influx of innovation, spurred by internet-based technology, offers one such moment. [source] More Difficult to Believe?INTERNATIONAL JOURNAL OF SYSTEMATIC THEOLOGY, Issue 1 2001Luther on Divine Omnipotence This article considers Luther's statement in thesis 21 of the 1545 doctoral disputation of Petrus Hegemon (1545) concerning the difficulty of belief in creatio ex nihilo, and suggests that this difficulty shapes the later Luther's theology in significant ways. The difficulty is reconstructed as a gradual movement into the mystery of the creatio ex nihilo. The first site of difficulty correlates the knowledge of creatures as particulars with the knowledge of the Creator as the source of existence. The move towards a second site is propelled by the question of inevitable death, which Luther answers by moving from material and natural generation to the resurrection and then to the creatio ex nihilo. At the third site, Luther addresses such disturbing questions as the suffering of the righteous, the historical cycle of political power, and the harshness of reprobation. He answers these questions by integrating the symmetrical biblical statements of the annihilatio and the creatio with a theological theory of divine omnipotence. God's hiddenness is understood as God's omnipotence working at the specific locations of self-negation, as well as behind the ebb and flow of historical-political contingency. Faith presses into the hidden mystery, grounded in the certainty that all things are effected by the Creator whose nature is self-giving goodness, and established by the hope that the light of glory will determine more fully the God who is to be honored above all. [source] Skills under threat: the case of HIV/AIDS in the mining industry in ZimbabweJOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 5 2006Caroline N. Matangi Abstract The Zimbabwe mining industry is currently battling to arrest further spread of the HIV/AIDS crisis in workplaces, especially its impact on labour productivity. Labour in the closed community of mines has been greatly susceptible to HIV/AIDS infection. The current AIDS incidence in the mine sites is estimated at a weighted average of 15,per,cent amongst miners, with the largest category of workers,the 30,39 years age group,also constituting the worst affected category. Given the current state of the country's economy and consequently its adverse impact on the lifestyle of miners, the pandemic is expected to increase. This paper builds on the work of the ILO (1995) involving a survey of 18 various firms/institutions. The survey was carried out in Zambia in order to assess the impact of HIV/AIDS on the productive labour force. The survey revealed that many of the firms are experiencing irregular work attendance, ,wasted' training as some of the trained workers are constantly ill or die, high medical bills, funeral costs and reduced productivity and profits. An analysis of data on the main causes of death in 1993 shows that at least 61.8,per,cent of deaths could be attributed to causes that are very closely related to HIV/AIDS complications. Based on points highlighted by respondents and analysis of symptoms suffered, it was observed that HIV/AIDS tended to affect most general workers (36.8,per,cent), followed by the lower management (30.9,per,cent) and the middle management (20.6,per,cent). Comparatively, 11.8,per,cent of the deaths in 1993 belonged to the top management. Although it is hard to appreciate the meaning of the figures without knowledge of the number of people in each category, it nevertheless helps to form a clear picture of the impact of HIV/AIDS on industry. This paper seeks to further investigate the impact of HIV/AIDS on the productive labour force, by focusing on one particular industry,mining,using a blend of research methods to collect the data. This paper examines the impact of HIV/AIDS on the productive labour force and management responses. It forms part of the findings of data gathered in 2001 in the mining industry in Zimbabwe, to examine factors affecting management responses to HIV/AIDS in the mine sites. Zimbabwe is a country with a complex historical legacy of mine labour. This phenomenon can largely be attributed to the production oriented nature of the mining industry. Mines focus mainly on mineral extraction and as a result the bulk of mine workers tend to be production workers whose skills have developed over long periods of time. Production workers on mines have a tradition of long-term employment. This phenomenon has meant that labour in the mines is hard to replace as a result of skills, especially tacit knowledge, acquired over many years. Thus while the recent closure of some gold mines, largely due to low commodity prices, has meant that more miners are available in the labour market, this situation has not necessarily eased the process of replacing labour lost to the HIV/AIDS epidemic, as certain skills are firm specific. Production workers are predominantly male with the bulk falling in the 35,39 years age group. Most mine workers reside in mine villages, a colonial legacy that ensured miners were close to the workplace. The village system is a system of housing labourers, which demonstrates capitalistic methods of controlling labour and minimising costs. Of significance in this study's background is how the village system has come to be viewed as a factor in the spread of HIV/AIDS in the mining communities, because of its ,closed' nature. It is against this complex historical backdrop that the paper turns to examine the impact of the HIV/AIDS pandemic on production workers and management responses to the crisis using the Resource Based View of the Firm model (RBV), one of the theories in the Strategic Human Resource Management (SHRM) tradition. RBV was chosen for this study out of many HRM models that exist, because this theory, in particular, explains why it is advantageous for sites to use their ,unique' firm based resources in order to achieve sustainable competitive advantage. Given this rationale it was, therefore, presumed that this theory would best apply in mines battling with the adverse impact of HIV/AIDS on productivity, especially in the light of the harsh national economic climate, which would likely place limitations on response mechanisms. Further, the issue of firm-specific skills was also taken into consideration as an important factor in the mines, limiting their ability to resort to external solutions. Thus, given these factors, RBV was deemed the most appropriate model. The study finds that the pandemic depresses labour productivity through a number of significant ways: increased rate of HIV/AIDS induced absenteeism gradual labour turnover as a result of AIDS induced morbidity; and consequently declining skills availability, particularly firm-specific skills. Maintaining labour productivity in the face of gradually diminishing skills and indisposed labour will be key to softening the adverse economic consequences of the pandemic in the mines. To reduce the threat to labour productivity, mines must find ways of utilising, to the maximum extent practicable, existing skills. Results indicate that a move towards the utilisation of existing miners is the most favoured response mechanism in most mines. Utilising existing miners enables mines from spending financial resources on avoidable recruitment and training and quite often mechanisation, which may not necessarily be compatible with the old infrastructure in certain mines.

Seefeldt Abstract The work presented here was motivated by the premise that the amorphous state serves as a medium to study cocrystal formation. The molecular mobility inherent to amorphous phases can lead to molecular associations between different components such that a single crystalline phase of multiple components or cocrystal is formed. Cocrystallization pathways and kinetics were investigated from amorphous equimolar phases of carbamazepine and nicotinamide using hot-stage polarized microscopy (HSPM), hot-stage Raman microscopy (HSRM), differential scanning calorimetry (DSC), and X-ray powder diffraction (XRPD). Nonisothermal studies revealed that amorphous phases generate cocrystals and that thermal history affects crystallization pathways in significant ways. Two different pathways to cocrystal formation from the amorphous phase were identified: (1) at low heating rates (3°C/min) a metastable cocrystalline phase initially nucleates and transforms to the more stable cocrystalline phase of CBZ,NCT, and (2) at higher heating rates (10°C/min) individual components crystallize, then melt and the stable cocrystalline phase nucleates and grows from the melt. Isothermal studies above the Tg of the amorphous equimolar phase also confirm the nucleation of a metastable cocrystalline phase from the amorphous state followed by a solid phase mediated transformation to the stable cocrystalline phase. Cocrystallization kinetics were measured by image analysis and by thermal analysis from small samples and are described by the Avrami,Erofeev model. These findings have important implications for the use of amorphous phases in the discovery of cocrystals and to determine the propensity of cocrystallization from process-induced amorphization. © 2007 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 96: 1147,1158, 2007 [source] Beyond the Dilemma of Difference: The Capability Approach to Disability and Special Educational NeedsJOURNAL OF PHILOSOPHY OF EDUCATION, Issue 3 2005Lorella Terzi In her recent pamphlet Special Educational Needs: a new look (2005) Mary Warnock has called for a radical review of special needs education and a substantial reconsideration of the assumptions upon which the current educational framework is based. The latter, she maintains, is hindered by a contradiction between the intention to treat all learners as the same and that of responding adequately to the needs arising from their individual differences. The tension highlighted by Warnock, which is central to the debate in special and inclusive education, is also referred to as the ,dilemma of difference'. This consists in the seemingly unavoidable choice between, on the one hand, identifying children's differences in order to provide for them differentially, with the risk of labelling and dividing, and, on the other, accentuating the ,sameness' and offering common provision, with the risk of not making available what is relevant to, and needed by, individual children. In this paper, I argue that the capability approach developed by Amartya Sen provides an innovative and important perspective for re-examining the dilemma of difference in significant ways. In particular, I maintain that reconceptualising disability and special needs through the capability approach makes possible the overcoming of the tension at the core of the dilemma of difference, whilst at the same time inscribing the debate within an ethical, normative framework based upon justice and equality. [source] Subtle, Pervasive, Harmful: Racist and Sexist Remarks in Public as Hate SpeechJOURNAL OF SOCIAL ISSUES, Issue 2 2002Laura Beth Nielsen Using field observations and 100 in-depth interviews with participants recruited from public places in Northern California, this article documents the experience of being the target of hate speech in public places. Focusing on racist and sexist hate speech (as participants define the phenomenon), I show that there is a range of experiences with hate speech and that it is often quite subtle, leaving all but intended victims unaware that it occurs. These data also show that such interactions occur with regularity and leave targets harmed in significant ways. There can be little doubt that members of traditionally disadvantaged groups face a strikingly different reality on the street than do members of privileged groups. Although the legal status of hate speech remains ambiguous, its harms are not. [source] GENOCIDE AND THE MORAL AGENCY OF ETHNIC GROUPSMETAPHILOSOPHY, Issue 3-4 2006KAREN KOVACH Abstract: Genocide is the deliberate destruction, in whole or in part, of a people. Typically, it is a crime that is committed by a people. In this essay, I propose an analysis of the concept of an ethnic identity group, which is, I argue, the concept of ethnicity at issue in many important discussions of group rights, group acts, and the moral responsibility of group members for the acts of the groups to which they belong. I develop the account of collective agency presupposed by this analysis and explore its implications for assessments of individual moral responsibility for genocide. I argue, further, that among other advantages over culturalist approaches to questions about group rights, the approach that follows from the concept of an ethnic identity group sheds light on the specific moral wrong of genocide. I reply to individualist objections to the idea that ethnic group membership may be morally significant and argue that morally adequate responses to genocide presuppose acknowledgment of the fact that groups act and are acted upon in morally significant ways. [source] Nonprofit association CEOs how their context shapes what, how, and why they learnNONPROFIT MANAGEMENT & LEADERSHIP, Issue 1 2007John J. Sherlock This qualitative study explored the learning experiences of twelve national nonprofit membership association CEOs using a phenomenological research design. While the professional context of an organization's chief executive is considered unique from other executive positions, the impact of this context on what and how CEOs learned was unclear. The findings describe association CEO learning as being affected in significant ways by the politically charged context in which the nonprofit association CEO operates with his or her board of directors. Power imbalances with staff and the board make learning through traditional organizational dialogue a less useful learning process for the CEOs. Furthermore, the feelings of isolation and vulnerability that are generated from the nonprofit association CEO context often cause CEOs to use private reflection and dialogue with their spouse as primary learning mechanisms. The study concludes that the association CEO context uniquely and profoundly shapes what, how, and why CEOs learn. Perhaps lacking the financial security of lucrative severance payments, which are often specified in employment contracts of for-profit CEOs, the nonprofit association CEO will often temper his or her actions to avoid personal vulnerability with a politically charged board of directors. [source] The Challenge of New SciencePERFORMANCE IMPROVEMENT QUARTERLY, Issue 2 2007Gordon Rowland A wide range of developments in science in recent years has altered our views of our world and ourselves in significant ways. These views challenge the direction of applied science and technology in many fields, including those associated with learning and performance in organizations. At the same time, they open up opportunities and possibilities. To take advantage, new approaches based on different assumptions are implied. This article summarizes a set of concepts associated with complexity and relates them to work in organizations. The final article of the issue then relates these same concepts to human performance technology. [source] The Bible, Knowledge of God and Dei VerbumTHE HEYTHROP JOURNAL, Issue 2 2001Anthony Baxter How may an inquiring person fittingly look upon the Bible? In what manner can a person's attention to the Bible assist them to knowledge? For a Catholic Christian analysis, what ideas are suitable about the place of the Bible in relations between God and humans, and in appropriation by a person today of whatever divine disclosure or revelation is at hand? This article outlines reflections on these matters. Links are apparent with key points in Vatican II's Dei Verbum. The first of four sections concerns a fundamentalist outlook. Section II has to do with certain limited but significant ways in which a person may look on the Bible: ways similar to ways in which a person may look on other texts. Section III pauses on inquiries into ,deep, inner' matters of life where the person inquiring does not proceed from a perspective of Catholic Christian faith. Section IV surveys a broad range of thoughts that may aptly be endorsed from within a perspective of Catholic Christian faith. The thoughts concern the nature of the situation by which a Catholic Christian person today can advance in knowledge of God: in appropriation of divine disclosure. Ways in which a person may look on the Bible that go beyond those exhibited earlier are now made explicit. (The article fully allows that numerous views held by one or another follower of Jesus who does not adhere to Roman Catholicism may, in respects at stake, harmonize with a Catholic Christian faith-perspective.) [source] Making Trash into Treasure: Struggles for Autonomy on a Brazilian Garbage DumpANTHROPOLOGY OF WORK REVIEW, Issue 2 2008Kathleen Millar Abstract In recent years, the expansion of types of work that fall outside the category of formal waged employment challenge many of our anthropological conceptions of labor, class politics and contemporary capitalism. This paper addresses the need to rethink the meaning of work in the context of neoliberal capitalism by exploring the formation of new worker subjectivities and practices among catadores: informal workers who collect and sell recyclable materials on a garbage dump in Rio de Janeiro, Brazil. Based on ethnographic research conducted among catadores from June through August of 2005 and in January 2007, this paper provides an analysis of the labor conditions, social relations, and forms of political organizing that have emerged on the garbage dump and which differ in significant ways from those found in situations of formal wage labor. Ultimately, this paper argues that while neoliberal capitalism has led to increased unemployment and underemployment among vulnerable populations in cities worldwide, the practices of those struggling to earn a living in urban informal economies are creating new spaces for alternative economic practices, social relations, and class politics today. [source] Pricing Weather Derivatives using a Predicting Power Time Series Process,ASIA-PACIFIC JOURNAL OF FINANCIAL STUDIES, Issue 6 2009Chuang-Chang Chang Abstract This paper extended the Cao-Wei (2004, JFM) model to construct a theoretical model for pricing weather derivatives in two significant ways. One adopted a time series model developed by Campbell and Diebold (2005, JASA) to describe the dynamics of temperature. The advantage of using Campbell and Diebold's time series model to describe the temperature dynamics is that it can not only take the conditional mean of temperature coming from trend, seasonal, and cyclical components but also allow for the conditional variance dynamics. The other purpose of this paper is to use an extended power utility function, instead of Cao and Wei's constant proportional risk aversion (CPRA) utility function. The extended power utility function could exhibit decreasing, constant, and increasing relative risk aversion. Eventually, we find that the prices of weather derivatives can be determined by weather conditions, discount factors, and forward premiums. Additionally, these sources have close relations with some risk aversion parameters. Furthermore, the results are consistent with Cao and Wei's condition under some specific parameter assumptions.
