Kinds of Examination Terms modified by Examination Selected AbstractsTHE ESTABLISHMENT OF A POLICE GANG UNIT: AN EXAMINATION OF ORGANIZATIONAL AND ENVIRONMENTAL FACTORS,CRIMINOLOGY, Issue 1 2001CHARLES M. KATZ Although researchers have begun to document the programs and activities performed by police gang units, little research has examined why police gang units are created and why they have responded to local gang problems in the way they have over the past 10 years. Using a multimethodological research design, the present study examines the factors that shaped a Midwestern police department's response to its community's gang problem. The results from the present study lend support for the institutional perspective. The data suggest that the gang unit was created as a consequence of pressures placed on the police department from various powerful elements within the community and that, once created, the unit's response was largely driven by its need to achieve and maintain organizational legitimacy. [source] A CROSS-CULTURAL EXAMINATION OF THE LINK BETWEEN CORPORAL PUNISHMENT AND ADOLESCENT ANTISOCIAL BEHAVIOR,CRIMINOLOGY, Issue 1 2000RONALD L. SIMONS Several studies with older children have reported a positive relationship between parental use of corporal punishment and child conduct problems. This has lead some social scientists to conclude that physical discipline fosters antisocial behavior. In an attempt to avoid the methodological difficulties that have plagued past research on this issue, the present study used a proportional measure of corporal punishment, controlled for earlier behavior problems and other dimensions of parenting, and tested for interaction and curvilinear effects. The analyses were performed using a sample of Iowa families that displayed moderate use of corporal punishment and a Taiwanese sample that demonstrated more frequent and severe use of physical discipline, especially by fathers. For both samples, level of parental warmth/control (i.e., support, monitoring, and inductive reasoning) was the strongest predictor of adolescent conduct problems. There was little evidence of a relationship between corporal punishment and conduct problems for the Iowa sample. For the Taiwanese families, corporal punishment was unrelated to conduct problems when mothers were high on warmth/control, but positively associated with conduct problems when they were low on warmtwcontrol, An interaction between corporal punishment and warmth/Wcontro1 was found for Taiwanese fathers as well. For these fathers, there was also evidence of a curvilinear relationship, with the association between corporal punishment and conduct problems becoming much stronger at extreme levels of corporal punishment. Overall, the results are consistent with the hypothesis that it is when parents engage in severe forms of corporal punishment, or administer physical discipline in the absence of parental warmth and involvement, that children feel angry and unjustly treated, defy parental authority, and engage in antisocial behavior. [source] SCHISTOSOMIASIS JAPONICA IDENTIFIED BY LAPAROSCOPIC AND COLONOSCOPIC EXAMINATIONDIGESTIVE ENDOSCOPY, Issue 2 2010Keiko Hosho A 45-year-old Philippine woman who came from Mindanao Island was admitted to our hospital with a complaint of epigastric discomfort. Abdominal ultrasonography and computed tomography demonstrated a network pattern and linear calcification in the liver. Laparoscopic examination showed numerous yellowish, small speckles over the liver surface. The liver surface was separated into many small blocks by groove-like depressions, demonstrating a so-called tortoise shell pattern. Conventional colonoscopy and narrow-band imaging showed irregular areas of yellowish mucosa, and diminished vascular network and increased irregular microvessels extending from the descending colon to the rectum. Liver biopsy showed many Schistosoma japonicum eggs in Glisson's capsule and colon biopsy showed many S. japonicum eggs in the submucosal layer. These findings established a diagnosis of schistosomiasis japonica. The present case is imported schistosomiasis japonica. Even though new cases have not occurred recently in Japan, we should remain aware of schistosomiasis japonica for patients who came from foreign epidemic areas. [source] EXAMINATION OF RESPIRATORY AND CIRCULATORY DYNAMICS DURING EXAMINATION USING A THIN GASTROINTESTINAL ENDOSCOPE IN ADVANCED-AGE SUBJECTSDIGESTIVE ENDOSCOPY, Issue 2 2007Miyako Niki Background:, Endoscopic examination influences cardiovascular hemodynamics. Upper gastrointestinal examinations are currently performed with a thin endoscope. In the present study, respiratory and circulatory dynamics and autonomic nervous activity using a thin endoscope (XP260) or a standard endoscope (XQ240) were investigated. Methods:, The subjects were 25 healthy adults aged less than 60 years (middle-aged group) and 15 healthy adults aged 60 years or older (advanced-age group). Percutaneous oxygen saturation, tonometric blood pressure, heart rate, and autonomic nervous activity were evaluated before the examination. After the endoscopic procedure, a questionnaire survey regarding examination-related stress was conducted. Results:, In the questionnaire survey, the proportion of subjects who answered ,very stress free' in the thin endoscope group was significantly higher than that in the standard endoscope group. The low frequency power of blood pressure variability (LFBP), an indicator of sympathetic nervous activity, was significantly lower during the thin endoscopic procedure than during the standard endoscopic procedure. Moreover, the ratio of low frequency power to high frequency power of heart rate variability (LFRR/HFRR), an indicator of sympathetic nervous activity, was significantly lower during thin endoscopic procedure than during the standard endoscopic procedure. The maximum rates of change in the LFBP and HFRR powers in the advanced-age group using thin and standard endoscopic procedures were significantly lower than in the middle-aged group. Conclusions:, The findings, although not in cross-over study, suggest that a thin endoscope has a less marked influence on circulatory kinetics. Gastrointestinal endoscopic examinations using a thin endoscope might reduce complications related to endoscopic screening examinations in advanced-age subjects. [source] MIND IS PRIMARILY A VERB: AN EXAMINATION OF MISTAKEN SIMILARITIES BETWEEN JOHN DEWEY AND HERBERT SPENCEREDUCATIONAL THEORY, Issue 3 2008Robin L. ZebrowskiArticle first published online: 20 AUG 200 However, one must look beyond the surface similarities of Dewey and Spencer and recognize the drastically divergent views that each held on those very foundational notions upon which each built his educational program. In this essay, Robin Zebrowksi examines the theories of evolution, the directionality of organism and environment interaction, the agency of the individual, and the conceptualizations of progress in the respective works of Dewey and Spencer. Their underlying beliefs about the world and how it operates show that their philosophies cannot be reconciled. The educational theories that follow from these discrepancies, Zebrowski concludes, have incompatible and distinct implications for the classroom. [source] A CRITICAL EXAMINATION OF THE SUITABILITY AND LIMITATIONS OF PSYCHOLOGICAL TESTS IN FAMILY COURTFAMILY COURT REVIEW, Issue 2 2007Steven K. Erickson Psychologists are frequently consulted by the courts to provide forensic evaluations in a variety of family court proceedings. As part of their evaluations, psychologists often use psychological tests to assess parents, guardians, and children. These tests can have profound effects on how psychologists arrive at their opinions and are often cited in their reports to the court. However, psychological tests vary substantially in their suitability for these purposes. Most projective tests in particular appear to possess little scientific merit for evaluations within family court proceedings. Despite these serious limitations, expert testimony derived from evaluations using both projective and objective tests is often admitted uncontested. This article reviews the psychometric properties of psychological tests that are widely used in family court proceedings, cautions against their unfettered use, and calls upon attorneys to inform themselves of the limitations of evaluations that incorporate these tests. [source] AN EXAMINATION OF THE CONTENT OF COMMUNITY FINANCIAL REPORTS IN QUEENSLAND LOCAL GOVERNMENT AUTHORITIESFINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 4 2008Trevor Stanley Annual reports, including general purpose financial statements, have been adopted as a key mechanism by which public sector entities discharge their accountability. However, there is concern about the complexity of public sector general purpose financial statements and consequently their effectiveness as an accountability mechanism. In Australia, the Queensland government has moved to address this issue in local government authorities by introducing a Community Financial Report as a means of simplifying the financial statements. A feature of this initiative was the lack of prescription given to local government authorities in the preparation of this report. This paper examines the form and content included in Community Financial Reports and also uses a disclosure index to determine the level of disclosure in the reports. The results of this research show that the form and content of the Community Financial Reports varied considerably. There was no definitive style, with each report being unique. The disclosure index revealed low levels of disclosure by local government authorities in the first year of the report as well as a lack of analysis of the Statements of Financial Performance, Position and Cash Flows. As well, there was a significant difference in the disclosures made by rural local government authorities compared with urban local government authorities. The results of this research will be of interest to local government authorities and local government regulators as they aim to provide useful, understandable information for stakeholders.

[source] EXAMINATION OF DIEL CHANGES IN GLOBAL TRANSCRIPT ACCUMULATION IN SYNECHOCYSTIS (CYANOBACTERIA),JOURNAL OF PHYCOLOGY, Issue 3 2006Rochelle G. Labiosa Phytoplankton in nature must acclimate to a wide range of light conditions resulting from diel light cycles, ocean circulation and mixing, cloud cover, and the variable bio-optical characteristics of the water column. In this study, we used whole-genome cDNA microarrays to investigate the effects of a gradually fluctuating daily light cycle on gene expression in the cyanobacterium Synechocystis sp. strain PCC6803. From these data, we developed a conceptual framework depicting the diel regulation of metabolic pathways in the cell. The framework is focused on potential photoacclimation responses, including the regulation of the photosystems, cell division, and DNA replication. The mRNA abundance of genes involved in many metabolic pathways, and particularly those encoding proteins that function in photosynthesis and DNA replication, changed markedly over the course of the day. The levels of mRNA encoding polypeptides important for the formation of the light-harvesting apparatus, photosystems I and II, and cell division were found in high concentrations during the day. The transcript levels of many genes encoding enzymes involved in anabolic processes also increased considerably during the day. In contrast, transposon transcripts and mRNAs encoding proteins involved in DNA replication, cell wall synthesis, and respiratory activity were not found in high concentrations during the day. Although gradually varying light exposure induced significant changes in transcript accumulation within Synechocystis, the direction of these changes differed between our study and previous studies in which there was an abrupt transition between irradiances.

Daisy Kaplan First page of article [source] A LONGITUDINAL EXAMINATION OF CONCOMITANT CHANGES IN TEAM LEADERSHIP AND CUSTOMER SATISFACTIONPERSONNEL PSYCHOLOGY, Issue 3 2008ALAN G. WALKER For each of three 1-year time periods, we examined the relationship between changes in the team leadership of branch managers (as measured by employee ratings) and concomitant changes in customer satisfaction for branches of a regional bank. Specifically, for the time period 2001,2002, we examined concomitant changes in team leadership and customer service satisfaction with 68 branch managers; between 2002,2003 and 2003,2004 we examined these relationships for 46 and 40 of the remaining 68 branch managers, respectively. We expected that improvements (declines) in team leadership ratings would be accompanied by concomitant changes (i.e., improvement or decline) in customer satisfaction ratings. We found that, in 2 of the 3 time periods we examined, improvements (declines) in team leadership were related to improvements (declines) in customer satisfaction. We interpret these findings using the service climate literature. [source] COLONIALISM AND LONG-RUN GROWTH IN AUSTRALIA: AN EXAMINATION OF INSTITUTIONAL CHANGE IN VICTORIA'S WATER SECTOR DURING THE NINETEENTH CENTURYAUSTRALIAN ECONOMIC HISTORY REVIEW, Issue 3 2008Edwyna Harris colonialism; democracy; economic growth; institutional efficiency; water rights Institutional change in water rights in the nineteenth century Australian colony of Victoria raised institutional efficiency, which contributed to long-run economic growth. High-quality human capital and the extension of voting rights (franchise) were crucial for efficient institutional change in the water sector. Quality human capital (literacy) appeared to increase the rural population's awareness of the economic impact of the existing structure of water rights that may have constrained growth in the agricultural sector and reduced investment incentives. Extension of the franchise allowed the rural population to exert political pressure for enactment of change in water rights, which resulted in efficiency-enhancing policies and efficient institutions. The findings show these two factors were more important than Victoria's British colonial heritage in determining whether growth-enhancing institutional change took place. [source] A FURTHER EXAMINATION OF THE PRICE AND VOLATILITY IMPACT OF STOCK DIVIDENDS AT EX-DATES,AUSTRALIAN ECONOMIC PAPERS, Issue 3 2005BALASINGHAM BALACHANDRAN We examine the price and volatility reaction around stock dividend ex-dates for an Australian sample, over the period January 1992 to December 2000. We find that price reaction around stock dividend ex-dates provides positive abnormal returns both prior, and subsequent, to the abolishment of par value of shares in July 1998. When we partitioned the sample into financial, industrial non-financial and mining firms, the price reaction is found to be positive and significant only for industrial non-financial companies. Volatility of daily returns for periods subsequent to ex-dates is significantly greater than corresponding periods prior to announcement dates, while cumulative raw returns subsequent to ex-dates are significantly lower than periods prior to announcement dates for industrial non-financial companies. The magnitude of the price reaction is statistically significantly related to an increase in the volatility of daily returns and to a reduction in cumulative raw returns subsequent to the ex-dates, for industrial non-financial companies. These findings support buying pressure hypothesis suggested by Dhatt et al. (1994, 1996). [source] Characteristics of Important Stopover Locations for Migrating Birds: Remote Sensing with Radar in the Great Lakes BasinCONSERVATION BIOLOGY, Issue 2 2009DAVID N. BONTER ave terrestre migratoria; migración; radar; sitios de escala temporal; WSR-88D Abstract:,A preliminary stage in developing comprehensive conservation plans involves identifying areas used by the organisms of interest. The areas used by migratory land birds during temporal breaks in migration (stopover periods) have received relatively little research and conservation attention. Methodologies for identifying stopover sites across large geographic areas have been, until recently, unavailable. Advances in weather-radar technology now allow for evaluation of bird migration patterns at large spatial scales. We analyzed radar data (WSR-88D) recorded during spring migration in 2000 and 2001 at 6 sites in the Great Lakes basin (U.S.A.). Our goal was to link areas of high migrant activity with the land-cover types and landscape contexts corresponding to those areas. To characterize the landscapes surrounding stopover locations, we integrated radar and land-cover data within a geographic information system. We compared landscape metrics within 5 km of areas that consistently hosted large numbers of migrants with landscapes surrounding randomly selected areas that were used by relatively few birds during migration. Concentration areas were characterized by 1.2 times more forest cover and 9.3 times more water cover than areas with little migrant activity. We detected a strong negative relationship between activity of migratory birds and agricultural land uses. Examination of individual migration events confirmed the importance of fragments of forested habitat in highly altered landscapes and highlighted large concentrations of birds departing from near-shore terrestrial areas in the Great Lakes basin. We conclude that conservation efforts can be more effectively targeted through intensive analysis of radar imagery. Resumen:,Una etapa preliminar en el desarrollo de planes de conservación integrales implica la identificación de áreas utilizadas por los organismos de interés. Las áreas utilizadas por aves terrestres migratorias durante escalas temporales en la migración (períodos de parada) han recibido relativamente poca atención de investigación y conservación. Hasta hace poco, las metodologías para la identificación de sitios de parada en áreas geográficas extensas han sido escasas. Ahora, los avances en la tecnología de radar meteorológico permiten la evaluación de patrones de migración de aves en escalas espaciales grandes. Analizamos datos de radar (WSR-88D) registrados en seis sitios en la cuenca de los Grandes Lagos (E.U.A.) durante la migración en las primaveras de 2000 y 2001. Nuestra meta fue relacionar áreas con gran actividad migratoria con los tipos de cobertura de suelo y los contextos del paisaje correspondientes a esas áreas. Para caracterizar los paisajes circundantes a las localidades de parada, integramos los datos de radar y de cobertura de suelo a un sistema de información geográfica. Comparamos las medidas del paisaje en un radio de 5 km en las áreas que consistentemente albergaron a grandes números de migrantes con los paisajes circundantes a áreas seleccionadas aleatoriamente y que eran utilizadas por relativamente pocas aves durante la migración. Las áreas de concentración se caracterizaron por tener 1.3 veces más cobertura forestal y 9.3 veces más cobertura de agua que las áreas con poca actividad migratoria. Detectamos una fuerte relación negativa entre la actividad de las aves migratorias y los usos de suelo agrícolas. El examen de eventos migratorios individuales confirmó la importancia de los fragmentos de hábitat boscoso en paisajes muy alterados y resaltó las grandes concentraciones de aves partiendo de áreas terrestres cercanas a la costa en la cuenca de los Grandes Lagos. Concluimos que los esfuerzos de conservación pueden ser abordados más efectivamente mediante el análisis intensivo de imágenes de radar. [source] Conservation Status as a Biodiversity Trend Indicator: Recommendations from a Decade of Listing Species at Risk in British ColumbiaCONSERVATION BIOLOGY, Issue 4 2005JAMES F. QUAYLE especies amenazadas; especies en peligro; estado del ambiente Abstract:,Species conservation status is commonly used as a broad-scale indicator of the state of biological diversity. To learn about its value for tracking trends, we examined provincial lists of terrestrial vertebrate species and subspecies at risk in British Columbia, Canada, for 1992 and 2002 to see whether changes in these lists reflected changes in the status of the taxa they represent. Examination of the case histories of individual species and subspecies showed that 65% of additions and deletions to the British Columbia Red List were the result of improvement in knowledge of species status, changes in assessment procedures, and refinements in taxonomy rather than actual changes in a species' status. Comparison to an alternate set of rank scores provided by NatureServe for taxa that appeared on both 1992 and 2002 British Columbia Red Lists revealed changes in status that were not reflected by movement from the list. Estimates of historical conservation status for species on the 1992 British Columbia Red List demonstrated ambiguity around the natural baseline with regard to tracking changes in list composition over time. We discourage the continued use of indicators based solely on conservation status as a means of tracking biodiversity. Instead we recommend advancing strategic indicators around species at risk based on long-term monitoring data, deliberate and explicitly stated baselines, and consistent methods of conservation ranking. Resumen:,El estatus de conservación de las especies comúnmente es utilizado como un indicador de escala amplia del estado de la diversidad biológica. En un esfuerzo por aprender sobre su valor para el seguimiento de tendencias, examinamos listas provinciales, para 1992 y 2002, de especies y subespecies de vertebrados terrestres en riesgo en Columbia Británica, Canadá, para ver si los cambios en estas listas reflejaban cambios en el estatus de los taxa que representan. El examen de la historia del caso de especies y subespecies individuales mostró que 65% de las adiciones y supresiones en la Lista Roja de Columbia Británica fueron el resultado de avances en el conocimiento del estatus de la especie, de cambios en los procedimientos de evaluación y de refinamientos en la taxonomía y no de cambios en el estatus de una especie. La comparación con un conjunto alternativo de valores de clasificación proporcionado por NatureServe para taxa que aparecieron tanto en la Lista Roja de Columbia Británica de 1992 como de 2002 reveló cambios en el estatus que no se reflejaron en movimientos en la lista. Estimaciones del estatus de conservación histórico de especies en la Lista Roja de Columbia Británica de 1992 demostraron ambigüedad alrededor de la línea de base natural en relación con el seguimiento de cambios en el tiempo en la composición de la lista. Desalentamos el uso continuo de indicadores basados solamente en el estatus de conservación como un medio para el seguimiento de biodiversidad. En cambio, recomendamos avanzar con indicadores estratégicos en torno a especies en riesgo con base en datos de monitoreo de largo plazo, en líneas básicas puestas de manifiesto deliberada y explícitamente y en métodos consistentes para la clasificación de la conservación. [source] Application of the New Keystone-Species Concept to Prairie Dogs: How Well Does It Work?CONSERVATION BIOLOGY, Issue 6 2000Natasha B. Kotliar This prompted Power et al. (1996) to refine the definition: keystone species have large effects on community structure or ecosystem function (i.e., high overall importance), and this effect should be large relative to abundance (i.e., high community importance). Using prairie dogs (Cynomys spp.) as an example, I review operational and conceptual difficulties encountered in applying this definition. As applied to prairie dogs, the implicit assumption that overall importance is a linear function of abundance is invalid. In addition, community importance is sensitive to abundance levels, the definition of community, and sampling scale. These problems arise largely from the equation for community importance, as used in conjunction with removal experiments at single abundance levels. I suggest that we shift from the current emphasis on the dualism between keystone and nonkeystone species and instead examine how overall and community importance vary (1) with abundance, (2) across spatial and temporal scales, and (3) under diverse ecological conditions. In addition, I propose that a third criterion be incorporated into the definition: keystone species perform roles not performed by other species or processes. Examination of how these factors vary among populations of keystone species should help identify the factors contributing to, or limiting, keystone-level functions, thereby increasing the usefulness of the keystone-species concept in ecology and conservation. Although the quantitative framework of Power et al. falls short of being fully operational, my conceptual guidelines may improve the usefulness of the keystone-species concept. Careful attention to the factors that limit keystone function will help avoid misplaced emphasis on keystone species at the expense of other species. Resumen: Se ha sugerido que el concepto de especie pilar no sea usado más en ecología y conservación, principalmente debido a que el concepto ha sido pobremente definido. Esto instigó a Power et al. (1996) a refinar la definición: las especies pilar tienen grandes efectos en la estructura de una comunidad o la función de un ecosistema (alta importancia en lo general), y este efecto debe ser grande en relación con la abundancia (alta importancia en la comunidad). Usando los perros de pradera (Cynomys spp) como ejemplo, revisé las dificultades operativas y conceptuales encontradas durante la aplicación de esta definición. Al aplicarse a perros de pradera, la suposición implícita de que la importancia en lo general es una función lineal de la abundancia es inválida. Además, la importancia en la comunidad es sensible a los niveles de abundancia, a la definición de comunidad y a la escala de muestreo. Estos problemas surgen, en gran medida, de la ecuación para la importancia en la comunidad, al ser usada conjuntamente con experimentos de remoción a un solo nivel de abundancia. Sugiero que el énfasis actual en la dualidad sobre especies pilares/no pilares cambie para examinar cómo varía la importancia en lo general y en la comunidad; (1) con la abundancia, (2) a lo largo de escalas espaciales y temporales, y (3) bajo diversas condiciones ecológicas. Además, propongo que sea incorporado un tercer criterio en la definición: las especies pilar llevan a cabo funciones no llevadas a cabo por otras especies o procesos. El análisis de cómo varían estos factores entre poblaciones de especies pilar ayudará a identificar los factores que contribuyen, o limitan las funciones a nivel pilar, incrementando con ello la utilidad del concepto de especie pilar en ecología y conservación. Aunque el marco de trabajo cuantitativo de Power et al. no llega a ser completamente operacional, mis guías conceptuales pueden mejorar la utilidad de este concepto. Una atención especial a los factores que limitan el funcionamiento pilar ayudaría a evitar un énfasis mal ubicado en especies pilar a costa de otras especies. [source] P02 Analysis of coupled patch test reactions to nickel, cobalt and chromateCONTACT DERMATITIS, Issue 3 2004Janice Hegewald Concomitant sensitizations to Nickel, Cobalt and Chromate are often observed among patch test patients. However, the reasons for being sensitized to two or more of these substances are not completely understood. Examination of IVDK (http://www.ivdk.org) patch test results with multivariate procedures has been conducted to further elucidate the mechanisms involved with these sensitizations and potential exposure factors that may have led to the concomitant sensitizations. Gender, age, occupational dermatitis, and construction work were considered and examined with multivariate logistic regression models with the dependent response variable being concurrent reactions to a metal pair versus no reactions. In addition to the aforementioned anamnestic data, examination of a poly-sensitizations variable (reactions to 1, 2, or 3 standard series allergens other than Nickel, Cobalt or Chromate) provided information regarding general susceptibility to positive patch test reactions. Combined reactions to Cobalt and Chromate were strongly linked to construction work (OR = 11.23 (7.46, 16.90)) and occupational dermatitis. Female patch test patients had a higher odds of a positive patch test reaction to both Nickel and Cobalt (OR = 4.73 (3.81, 5.87)). Sensitization to other, unrelated standard series substances was associated with concurrent reactions to all of the metal pairs. The association between construction work and Cobalt-Chromate reactions corresponds with the hypothesis that cement exposures lead to cobalt-chromate sensitizations. Individual susceptibility to delayed-type sensitizations, as represented by the poly-sensitization variable, also appears to be associated with coupled sensitizations to metals and warrants further examination.

Brazel First page of article [source] Possible common central pathway for resistin and insulin in regulating food intakeACTA PHYSIOLOGICA, Issue 4 2009C. Cifani Abstract Aim:, Adipose tissue has been the object of intense research in the field of obesity and diabetes diseases in the last decade. Examination of adipocyte-secreted peptides led to the identification of a unique polypeptide, resistin (RSTN), which has been suggested as a link between obesity and diabetes. RSTN plays a clearly documented role in blocking insulin (INS)-induced hypoglycaemia. As brain injection of INS affects feeding behaviour, we studied the possible interaction between INS and RSTN in food-deprived rats, measuring effects on food intake. In addition, we examined how RSTN might affect neuropeptide Y (NPY)-induced feeding, as studies have shown that rat RSTN can interfere with the NPY system. Methods:, Overnight food-deprived rats were injected into the third brain ventricle (3V) with either INS (10 or 20 mUI), RSTN (0.1,0.4 nmol/rat), or saline before access to food. Another group of rats was injected into the 3V with RSTN alone, NPY alone or RSTN plus NPY. Their food intake and body weight were measured. Results:, Our results confirm the hypophagic effect of RSTN on food deprivation-induced food intake, and more importantly, show that RSTN neither potentiates nor blocks the effects of INS on food intake, but does reduce the hyperphagic effect of NPY. Conclusion:, The observation that RSTN does not modify feeding INS-induced hypophagia, but does influence NPY-induced feeding, points to the possibility that RSTN may be involved in control of food intake through an NPY-ergic mechanism as INS. [source] Do early therapeutic alliance, motivation, and stages of change predict therapy change for high-risk, psychopathic violent prisoners?CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2010Devon L. L. Polaschek Background,Examination of the extent of offenders' engagement in change, and in rehabilitation programmes, is important to understanding success or failure following rehabilitation. In treatment programmes, the alliance between therapist and offender, and the therapy process itself appear central to progress offenders make that may reduce their criminal risk. But research with offenders seldom has measured therapeutic alliance and clinical writing suggests that it is difficult to form an alliance with those not ready to change their behaviour; especially with higher risk and psychopathic offenders. Aims and Methods,This study outlines the course of the therapeutic alliance in an 8-month treatment programme for high-risk, PCL-psychopathic violent prisoners. It examines relationships between early-treatment therapeutic alliance, therapists' global ratings of motivation to change, and initial stage of change on dynamic risk factors. In addition, it investigates which factors best predict who will complete treatment and change behaviourally during treatment. Conclusion,In this challenging, high-needs client group, early-programme stage of change, therapists' perceptions of motivation, therapeutic alliance and psychopathy did not predict how much change prisoners made. Regardless of initial levels, prisoners whose alliance increased the most over the course of treatment made the most change. Copyright © 2010 John Wiley & Sons, Ltd. [source] Temporal reliability of psychological assessments for patients in a special hospital with severe personality disorder: a preliminary noteCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2005Professor P. Tyrer Background The new programme for assessing those with dangerous and severe personality disorder relies heavily on psychological assessments of personality disorder and risk. Methods The temporal reliability of assessments of psychopathy (PCL-R), risk (HCR-20) and personality was assessed using the International Personality Disorder Examination (IPDE) in 15 randomly selected male prisoners in a high secure hospital carried out at intervals varying between a mean of nine and 19 months after initial assessments by a variety of assessors. Results Using the intra-class correlation coefficient the agreement varied between0.57 (HCR-20), 0.58 (PCL-R) and 0.38-0.70 for IPDE personality disorders, with the best agreement for antisocial personality disorder (0.70). Comment These levels of agreement are consistent with other recent work on temporal reliability of personality instruments but are a little too low for confidence in these measures alone in the assessment process.

[source] Contesting the Curriculum: An Examination of Professionalism as Defined and Enacted by Australian History TeachersCURRICULUM INQUIRY, Issue 3 2007FIONA HILFERTY ABSTRACT In this article, I present an analysis of professionalism as defined and enacted by the History Teachers' Association of New South Wales (HTANSW). This analysis was part of a larger doctoral project (2000,2005) in which I employed critical qualitative inquiry to compare and contrast the contribution that two subject teaching associations (science and history) make to the project of teacher professionalism in Australia. My aim for this project was to explore what professionalism means in practice for a unique group of teachers: those who have made an active and fundamental commitment to their subject community by voluntarily serving on the executive committee of their subject-based professional association. In this article, I present findings from the case account of the HTANSW,an organization that operates locally as a professional teacher community and a representative organization for school-based history teachers. This case account details the manoeuvrings of an association that powerfully asserts an expansive role for history teachers as both contributors to, and critical commentators on, curriculum policy. In this article, I conceptualise the actions of this association as an enacted form of teacher professionalism. Drawing on study findings, I explicate my conception of professionalism as an enacted discourse of power and I show how this discourse is enacted in subject-specific ways. [source] How predictive is a cervical smear suggesting glandular neoplasia?CYTOPATHOLOGY, Issue 2 2002M. E. MATHERS How predictive is a cervical smear suggesting glandular neoplasia The prevalence of endocervical adenocarcinoma and its precursors has increased, in part due to increased diagnostic awareness of these lesions. To date, limited information has been published regarding the predictive value of glandular abnormalities in cervical smears. This study details the histological follow up of 418 cervical smears showing glandular abnormality, reported in our department over a six year period from 1993 to 1998. Histological follow up was available for 395 of the 418 smears (94.50%). The overall positive predictive value (PPV) for this group of smears was 72.66% for either significant glandular or squamous pathology (at least low grade cervical glandular intraepithelial neoplasia or CIN2 on follow up biopsy), and 55.70% for significant glandular pathology alone. Examination of subcategories of abnormal glandular smear showed that the PPV increased with the degree of abnormality reported within the smears. [source] Early molecular events in the assembly of the focal adhesion-stress fiber complex during fibroblast spreadingCYTOSKELETON, Issue 3 2004Baruch Zimerman Cell adhesion to the extracellular matrix triggers the formation of integrin-mediated contact and reorganization of the actin cytoskeleton. Examination of nascent adhesions, formed during early stages of fibroblast spreading, reveals a variety of forms of actin-associated matrix adhesions. These include: (1) small (,1 ,m), dot-like, integrin-, vinculin-, paxillin-, and phosphotyrosine-rich structures, with an F-actin core, broadly distributed over the ventral surfaces of the cells; (2) integrin-, vinculin-, and paxillin-containing "doublets" interconnected by short actin bundles; (3) arrays of actin-vinculin complexes. Such structures were formed by freshly plated cells, as well as by cells recovering from latrunculin treatment. Time-lapse video microscopy of such cells, expressing GFP-actin, indicated that long actin cables are formed by an end-to-end lining-up and apparent fusion of short actin bundles. All these structures were prominent during cell spreading, and persisted for up to 30,60 min after plating. Upon longer incubation, they were gradually replaced by stress fibers, associated with focal adhesions at the cell periphery. Direct examination of paxillin and actin reorganization in live cells revealed alignment of paxillin doublets, forming long and highly dynamic actin bundles, undergoing translocation, shortening, splitting, and convergence. The mechanisms underlying the assembly and reorganization of actin-associated focal adhesions and the involvement of mechanical forces in regulating their dynamic properties are discussed.

Malhotra ABSTRACT As the field of decision sciences in general and operations management in particular has matured from theory building to theory testing over the past two decades, it has witnessed an explosion in empirical research. Much of this work is anchored in survey-based methodologies in which data are collected from the field in the form of scale items that are then analyzed to measure latent unobservable constructs. It is important to assess the invariance of scales across groups in order to reach valid, scientifically sound conclusions. Because studies have often been conducted in the field of decision sciences with small sample sizes, it further exacerbates the problem of reaching incorrect conclusions. Generalizability theory can more effectively test for measurement equivalence in the presence of small sample sizes than the confirmatory factor analysis (CFA) tests that have been conventionally used for assessing measurement equivalency across groups. Consequently, we introduce and explain the generalizability theory (G-theory) in this article to examine measurement equivalence of 24 manufacturing flexibility dimension scales that have been published in prior literature and also compare and contrast G-theory with CFA. We show that all the manufacturing flexibility scales tested in this study were invariant across the three industry SIC groups from which data were collected. We strongly recommend that G-theory should always be used for determining measurement equivalence in empirical survey-based studies. In addition, because using G-theory alone does not always reveal the complete picture, CFA techniques for establishing measurement equivalence should also be invoked when sample sizes are large enough to do so. Implications of G-theory for practice and its future use in operations management and decision sciences research are also presented.

Rossetti ABSTRACT Aftermarket sales and profits are becoming an increasingly important part of an original equipment manufacturer's (OEM) business model. Because replacement parts often do not require further manufacturing, OEMs act as intermediaries in the aftermarket. As with any intermediary, the OEM must concern itself with suppliers disintermediating its supply chain selling replacement parts directly to the OEM's customers. We frame supply chain disintermediation (SCD) as a principal,agent contracting problem between an OEM buyer and a supplier. Hypotheses relate contract conditions, goal incongruence, supplier capabilities and contract enforcement to SCD. The data are collected from the aerospace industry using a multimethod study, combining an Internet-based survey with archival data. Causal modeling with structural equation modeling (SEM) shows general support for the hypotheses. Particularly, SCD is positively related to buyer,supplier goal incongruence. The agency model offers insights that differ from previous transaction-cost-based models of buyer,supplier relationships. OEM buyers with a lucrative aftermarket should consider aligning goals through incentives rather than relying entirely on economic hostages associated with specific assets.

Syler ABSTRACT The accelerating diffusion of broadband Internet access provides many opportunities for the development of pedagogically robust Web-based instruction (WBI). While the supporting technology infrastructure of broadband disseminates, the attention of academic researchers focuses upon issues such as the drivers of student usage of WBI. Specifically, the research presented herein examined the impact of WBI on a student's aggregate course performance. We hypothesized that learning independence (LI) is a determinate factor in a student's use of WBI. In this study, we employed structural equation modeling techniques to examine the data and assess the direct and indirect effects of LI on WBI usage. The subjects, students in an introductory Computer Information Systems applications course, used a Web-based tutorial program for skills instruction. The findings of this study suggest that WBI usage has a significant impact on a student's course performance. Despite its plausibility, the effect of LI on WBI usage was not significant. However, we did conclude that two of the second order factors of the LI construct have a direct effect on a student's performance in the course. [source] Surgical extrusion of a crown-root fractured immature permanent incisor: 36 month follow-upDENTAL TRAUMATOLOGY, Issue 6 2007Zuhal K Abstract,,, Crown-root fracture is defined as a fracture involving enamel, dentin and pulp and can be classified as either complicated or uncomplicated. The tooth with crown-root fracture presents a lot of problems during coronal restorations and extraction was formerly used in many cases. But loss of a permanent incisor in a young patient may create severe emotional problems and alternative treatment approaches must be considered. This report presents the successful results of a surgical extrusion of a complicated crown-root fractured, immature permanent incisor in a 9-year-old boy. Examination 36 months after the trauma indicated that the treatment had provided functional and esthetic results. [source] Reattachment of subgingivally fractured central incisor with an open apexDENTAL TRAUMATOLOGY, Issue 3 2007Ece Eden Abstract,,, A case report of a 6-year-old girl with a fractured maxillary left central incisor with an open apex is presented. The procedure used to repair the fracture included flap surgery with an intrasulcular incision and endodontic treatment. The patient was called for 3 months regular follow-up to check the root formation. At the end of 32 months just before the root was obturated by guttaperka, she fractured the same tooth. Flap surgery was repeated and the tooth was restored. The root canal was obturated with a root filling paste and guttaperka as the apex was closed. Examination 10 months after treatment revealed good periodontal health, aesthetics and normal function. [source] | ||||||||||||||||||||||||||||||||||||||||||||||
