Variability of arterial blood pressure and classification of essential hypertension by multivariate statistical analysis.

The subjects included in the present study were 141 hospitalized patients with essential hypertension (EH) and 45 patients with EH complicated with apoplexy and myocardial infarction. Of the former 15 underwent a 24-hour measurement of direct arterial pressure under unrestricted conditions, and 45 were examined for functioning of the carotid sinus reflex. (1) Even among the hospitalized patients with EH, blood pressure (BP) showed large diurnal variations. Falls and spontaneous fluctuations in BP were observed at a time during nocturnal sleep. The lowest BP (the "dale" pressure) observed at that time remained almost unchanged throughout the night (S.D. less than or equal to 6 mmHg) for each patient. Since casual BP varies considerably during a day, other laboratory findings should also be taken into account for evaluation prior to initiating antihypertensive treatment. (2) The 186 patients with EH were classified by multivariate statistical analyses of laboratory findings into 4 clusters (types). Then, a new severity index was made in order to evaluate atherosclerotic and hypertensive changes in each patient. (3) A newly devised carotid sinus stimulator was used to enhance the distensibility of the carotid sinus. A decrease in systolic blood pressure (delta SBP) was observed after stimulation although differences in delta SBP were found between the 4 clusters. There was a positive correlation between delta SBP and the elastic modulus of the common carotid artery (r = 0.55, P less than 0.01). (4) Each cluster was characterized by differences in plasma renin activity and cardiovascular abnormalities. This classification is considered to be useful for the antihypertensive treatment.
firestarter – A Real-Time Fire Simulator

Many obstacles exist in attempting to graphically render physical phenomena that are highly fluid and ostensibly chaotic in nature. Fire is a prime example of such phenomena. Given the unrealizable computational complexity of chemical-atomic modeling, this paper explores how to best apply our current understanding of the physical fire model to balance computational stresses for optimal realism. Special emphasis is given specifically to the constraints imposed by real-time rendering, as opposed to production pipeline rendering, introducing firestarter – a real-time fire simulator developed by the author using OpenGL – which features some unique implementations of previously discussed topics.

The relationship between sexual and emotional promiscuity and infidelity

The main aim of the present study is to relate, for the first time, the sexual and emotional sides of infidelity, that is characterized by any form of close physical or emotional involvement with another person while in a committed relationship with promiscuity, which is typically defined by the search for the maximum sexual pleasure or how easily and often someone falls in love. Another aim was to investigate potential sex differences within both domains. For that, 369 participants (92 males and 277 females) answered to an online questionnaire that collected information about infidelity and promiscuity. More specifically, participants were asked to complete the revised Sociosexual Orientation Inventory (SOI-R), the Emotional Promiscuity (EP) Scale, and the Sexual and Emotional Infidelity (SEI) scale. In addition, some sociodemographic questions, as well as history of infidelity questions, were also asked. The analyses included Pearson correlations, ANOVA and t-tests. Results show that all domains are related, specifically sexual and emotional infidelity with sexual and emotional promiscuity.
LBcast: Load-balanced Broadcast Scheduling for low-duty-cycle Wireless Sensor Networks

Recently, broadcast scheduling for low-duty-cycle WSNs has been extensively studied. However, most of the existing solutions mainly focus on energy efficiency optimization in terms of total energy consumption and very few of them take into account the load balance, which is an important design objective in low-duty-cycle WSNs. In this paper, we propose an energy-efficient broadcasting schedule for low-duty-cycle WSNs, which approximately minimizes the maximum workload of nodes for broadcasting while achieving low total energy consumption. By capturing the spatiotemporal characteristic of broadcasting in low-duty-cycle networks, we first model our scheduling problem as the Directed Minimum Weighted-degree Steiner Tree Problem, which is NP-hard. To solve this problem, we devise the Load-Balanced Broadcasting Schedule (LBcast) algorithm. Further, we introduce how to implement it in a distributed way. Our simulation results reveal that compared with the existing solutions considering the optimization of total energy consumption, LBcast exhibits much better load balance and also achieves low total energy consumption.
Eléments d'évaluation de la qualité du service de transport ferroviaire

Comme on le sait, la norme ISO 9004-2 [1] definit l'installation rationnelle d'un systeme de qualite d'entreprise [2] [3], et se refere en particulier au secteur des services, dans la logique d'une orientation de l'organisation d'entreprise vers la garantie de la qualite, ou, autrement dit, vers la garantie des prestations, en termes d'adequation, d'efficacite et de fiabilite. On souhaite donc aborder dans cet article, sur la base de ces idees directrices, le theme des qualites techniques auxquelles une entreprise de services, en particulier si elle est caracterisee par une proportion elevee de biens materiels, doit satisfaire dans la mesure du possible pour garantir l'adequation entre les prestations proposees et celles qui sont effectivement realisees. L'article portera sur le service de transport ferroviaire et tout specialement sur les contenus de la norme UN19910(4) qui a ete elaboree sur la base de l'experience des secteurs electrique, electronique et des telecommunications, secteurs d'avant-garde en ce qui concerne les aspects cumulatifs de la qualite et de la securite.
Effects of Different Kinds of Exercise in the Gait Parameters of Elderly Women 03 ARTIGO RBME 431

Exercise type, intensity and frequency are important factors to produce changes in gait velocity. The aim of this study was to compare the effects of different exercise types in the gait kinematic parameters in elderly women, whereas anthropometry, functional capacity and physical activity level are considered. Fifty-six elderly women were grouped according to their specific physical activity (practice for more than 6 months): dancing (n = 10), strength training (n = 10), aquatic exercise training (n = 12) and walking (n = 11). In addition, an inactive female older group (n = 13), without engagement in regular physical activity for at least 02 months, participated in the study. The physical activity level (Baecke Questionnaire), functional capacity (AAHPERD battery) and the gait kinematic parameters (gait cycle and step length, gait cycle duration and velocity, cadence and single support phases, swing and double support duration) were measured. The results showed that the physical activity level in the control group was different from the one in the other groups (physically active). In relation to functional capacity, only the strength component was different between groups, indicating that the control group differs from the strength training group. Regarding the gait parameters, the control group was statistically different from the group dancing regarding gait cycle and step length. The results of this study indicate that the functional capacity and gait parameters of active and sedentary elderly females present few differences.
A mouse model of pathological small intestinal epithelial cell apoptosis and shedding induced by systemic administration of lipopolysaccharide

SUMMARY The gut barrier, composed of a single layer of intestinal epithelial cells (IECs) held together by tight junctions, prevents the entrance of harmful microorganisms, antigens and toxins from the gut lumen into the blood. Small intestinal homeostasis is normally maintained by the rate of shedding of senescent enterocytes from the villus tip exactly matching the rate of generation of new cells in the crypt. However, in various localized and systemic inflammatory conditions, intestinal homeostasis can be disturbed as a result of increased IEC shedding. Such pathological IEC shedding can cause transient gaps to develop in the epithelial barrier and result in increased intestinal permeability. Although pathological IEC shedding has been implicated in the pathogenesis of conditions such as inflammatory bowel disease, our understanding of the underlying mechanisms remains limited. We have therefore developed a murine model to study this phenomenon, because IEC shedding in this species is morphologically analogous to humans. IEC shedding was induced by systemic lipopolysaccharide (LPS) administration in wild-type C57BL/6 mice, and in mice deficient in TNF-receptor 1 (Tnfr1−/−), Tnfr2 (Tnfr2−/−), nuclear factor kappa B1 (Nfκb1−/−) or Nfĸb2 (Nfĸb2−/−). Apoptosis and cell shedding was quantified using immunohistochemistry for active caspase-3, and gut-to-circulation permeability was assessed by measuring plasma fluorescence following fluorescein-isothiocyanate–dextran gavage. LPS, at doses ≥0.125 mg/kg body weight, induced rapid villus IEC apoptosis, with peak cell shedding occurring at 1.5 hours after treatment. This coincided with significant villus shortening, fluid exudation into the gut lumen and diarrhea. A significant increase in gut-to-circulation permeability was observed at 5 hours. TNFR1 was essential for LPS-induced IEC apoptosis and shedding, and the fate of the IECs was also dependent on NFκB, with signaling via NFκB1 favoring cell survival and via NFκB2 favoring apoptosis. This model will enable investigation of the importance and regulation of pathological IEC apoptosis and cell shedding in various diseases.
Fueling Green Dining Intention: The Self-Completion Theory Perspective

This study aims to examine how self-identity of consumers influences intention to pay a premium to consume green food. Moreover, this research investigates the relationship between recollection of past dining experience and intention to consume green food. The self-completion theory (SCT) is to explain the compensatory effects of the preference to consume green food. Exposure to environmental information demonstrates the effects of priming. Two experiments were conducted to illustrate the effects of priming and recollection of past behavior that harmed the environment of consumers. The results show that after mere exposure to information on green dining, participants preferred to consume green food (priming effects). Similar results were obtained from the experiment where participants were asked to recall their past behaviors that harmed the environment. Asking individuals to recall past behavior proved to be an effective way to motivate patrons of green dining to find a moral equilibrium (compensation effects).
Studying Poverty and Inequality in Poor Countries: Getting to Grips with Structure

This paper describes an alternative to the currently dominant empirical research approaches to poverty in poor countries (econometric analyses of household surveys and 'participatory poverty assessments') based on cutting edge developments in mainstream sociology. Using ideas generated in the ‘critical realist’ tradition I propose that the study of the production, reproduction and reduction of poverty and inequality would be considerably advanced by the use of an ontology that sees all aspects of the world as structured in space and time. The structures which constitute ‘objects’, defined here as people, all other material animate and inanimate ‘things’, and structured social relations of all kinds, give them ‘causal powers’ or capacities to behave in particular ways, and ‘passive powers’ or specific susceptibilities to certain kinds of change. All structures can be usefully analysed from four perspectives: anatomy, physiology, dynamics and history. The paper provides examples of ways in which the structures and dynamics of material things are relevant for poverty and inequality. A fourperspective analysis of the 'structure of being' generates a conceptualisation of human poverty in terms of poverty-driven action, resource failures, personal suffering, unmet needs, and seriously harmful beliefs, all embedded in particular local livelihood and cultural contexts. A four-perspective analysis of social structures is linked to ongoing developments in mainstream sociology. The systematic use of this research approach would considerably increase understanding of poverty and inequality in poor countries. The next step is to use the framework inter-actively with grounded empirical research to develop and use an integrated suite of research instruments and modes of comparative analysis with both qualitative and quantitative aspects.
MODELING INTERNAL ORGANIZATIONAL CHANGE

Organizational change can be usefully conceptualized in terms of both its process and its content. Process refers to how change occurs. Content describes what actually changes in the organization. Theories and analyses of organizational change seek to explain why organizations change as well as what the consequences are of change. Empirical evidence on both questions is fragmentary and occasionally contradictory. Models that consider both process and content show the greatest potential for resolving this situation. Such models can be used to test social science theories as well as to evaluate programs of organizational change promulgated by consultants and practitioners. Basic organizational theory would be enhanced by greater attention to organizational change.
The Coopersmith Self-Esteem Inventory: A Construct Validation Study

The Coopersmith Self-Esteem Inventory (SEI) was examined using a modified version of the Sabers and Whitney model for construct validation. The SEI, Piers-Harris Children's Self-Concept Scale (CSCS), and Children's Social Desirability Scale (CSDS) were administered to 55 males and 50 females enrolled in six intact fifth-grade classes. Each student also received a teacher rating of self-concept using the Coopersmith Behavioral Academic Assessment Scale (BASE). Regression analyses indicated that the SEI has convergent validity with regard to the CSCS (p < .01) and BASE (p < .01), has discriminant validity with regard to the CSDS (p > .05), is sensitive to differences in achievement level (p < .01), and is internally consistent (coefficient alpha = .86). Intra-rater stability for the BASE ranged from . 85 to . 97; average inter-rater agreement was . 86.
The granting of forgiveness in an intergroup context: African and Asian social representations

The model for representing intergroup forgiveness suggested by Neto, Pinto & Mullet (2007a) has been extended through the examination of data from a large sample (n = 1036) of Asian (Cambodians and East Timorese) and African (Angolans, Guineans and Mozambicans) adults who have been personally affected by long-term wars and conflicts in their area. Exploratory and confirmatory factor analyses showed that a nine-factor model could adequately fit the whole set of data. Overall, a large majority of the participants agreed with the view that forgiveness as an intergroup process was conceivable. For a majority of the participants: (a) the aim of the intergroup forgiveness process is reconciliation with the former offender; (b) the process does not need to be strictly conditional on adequate reparation and compensation; (c) it should be democratic — in other words, forgiveness should not be decided solely by politicians, traditional or religious authorities; (d) it belongs to the forgiver—forgiven dyad — in other words, interference from the international community should be minimal; (e) it should be public (and not a negotiation between members of the elite) — forgiveness should be announced to the whole community using broad international languages; and (f) it should be an all-encompassing process, that is, it should encompass all the members of the requesting group, all the members of the forgiving group and all the offences. Le modèle de représentation du pardon intergroupe proposé par Neto, Pinto & Mullet (2007a) a été étendu à travers l’examen d’un échantillon large de données (n = 1036) recueillies en Asie (Cambodge et Timor Oriental) et en Afrique (Angola, Guinée-Bissau et Mozambique) auprès d’adultes ayant directement souffert des guerres et des conflits qui ont longtemps ravagé leurs pays. Des analyses factorielles exploratoires et confirmatoires ont montré qu’un modèle complexe à neuf facteurs pouvait rendre compte des données de manière adéquate. Une large majorité de participants est en accord avec l’idée que le pardon intergroupe est un concept qui a du sens. Pour une majorité de participants: (a) le but du pardon intergroupe est la réconciliation avec l’agresseur; (b) le processus de pardon intergroupe ne doit pas être strictement subordonné à des réparations ou compensations adéquates; (c) ce processus doit être démocratique — c’est-à-dire que le pardon ne doit pas être décidé par les politiciens ou les autorités religieuses ou traditionnelles; (d) ce processus appartient à la dyade pardonnant—pardonné — les interférences de la communauté internationale doivent se trouver réduites au minimum; (e) le processus doit être public et ne pas résulter d’une négociation secrète entre membres de l’élite — le pardon doit être annoncé à toute la communauté dans des langues internationales de grande communication; et (f) ce doit être un processus large englobant tous les membres du groupe demandeur, tous les membres du groupe qui pardonne, et tous les torts commis.
Adaptive geometric trajectory tracking control of quadrotor with finite-time convergence

This paper investigates the trajectory tracking problem for quadrotor with finite-time convergence via geometric approach. Based on a global geometric dynamic description on SE(3), we decompose the finite-time trajectory tracking control into two cascaded tracking loops: the position finite-time tracking control loop and the attitude finite-time tracking control loop. A finite-time controller based on exponential coordinate is proposed via a sliding mode approach, which avoids artificial singularity and redundancy. Further, an adaptive law is utilized to estimate the uncertainties of the mass and inertia matrix. Numerical results are presented to demonstrate the effectiveness of this trajectory tracking strategy.
Student beliefs (or metacognitive knowledge) about SLA reconsidered

In applied linguistics, interest in student beliefs (or metacognitive knowledge) about second language acquisition (SLA) is fairly recent, growing out of the emphasis on learner autonomy and on learner strategies in SLA. The purpose of this paper is to review those few studies that have been published so far, to give an outline of definitions of beliefs and research methodology, and finally to provide alternatives to these, based on recent developments in the social sciences. With a reconsideration of beliefs come reconsiderations of research data and methods.
Emotional labor and conflict in schools: Teacher perceptions of the emotional display rules necessary for negative teacher - student interactions

Teaching requires emotional work. Some days teachers experience positive emotions (joy, pride, hope) in conjunction with students learning new concepts or forming new relationships. Other days teachers experience negative emotions (frustration, annoyance, anger) in response to negative conflict between themselves and their students. The ability to interact with students, navigate emotions and appropriately express or suppress them can be challenging for educators. The emotional labor completed to express or suppress emotions based on job standards and norms (display rules) is explicitly studied in most service industries, but continues to be understudied in education. This paper provides a descriptive analysis of the emotional labor and emotional displays teachers experience during one specific portion of their workday, negative interactions with students. The study also describes teacher perceptions of and the training received for the emotional display rules (EDRs) necessary for such interactions. Study participants included 26 teachers and teaching assistants from one Mid-Atlantic charter school. The educators completed a short demographic survey and a 45-minute in-person interview. Interviews included 15 open-ended questions detailing the descriptions of negative teacher-student interactions, subsequent emotional responses and any relevant training received during pre-service, professional development sessions or through personal research. A review of the findings uncovered patterns in interactions, emotional displays and forms of training. Findings reveal that teachers experience emotional labor during negative teacher-student interactions in the absence of explicit display rules and training. Revealed sources of negative emotions for educators include: the interactions with students and the apparent lack of display rules and necessary emotion training. Teachers emphasized the need for training and explicit display rules. Although there is a wealth of literature on emotional labor, it continues to be an area under studied in education. This paper adds to the current body of literature and includes implications and recommendations for practice and future research in the area of explicit display rules for educators. We must continue to research and define EDRs for educators and provide them with the appropriate pre-service training and professional development in order to help them successfully navigate the challenging emotional labor they experience daily.
Cerebral CT venography.

PURPOSE To produce cerebral venograms with thin-section helical computed tomography (CT) and to assess their diagnostic utility. MATERIALS AND METHODS Thirty-six CT venograms were obtained in 33 patients after intravenous administration of iodinated contrast material. Eighteen patients had suspected dural sinus thrombosis. Twelve patients had tumor adjacent to a major venous structure. Three patients underwent CT venography during CT angiography. RESULTS Superior sagittal, transverse, and straight sinuses were identified on every CT venogram. Other veins were seen with high frequency. Dural sinus thrombosis was diagnosed in seven patients, with magnetic resonance (MR) venographic correlation in five patients. CT venograms were easier to interpret and had fewer artifacts than MR venograms. Relationships of tumor to adjacent cerebral venous structures were well shown on CT venograms. CONCLUSION CT venography yields detailed images of the intracranial venous circulation with consistently high quality. It is a rapid, useful method for diagnosis of dural sinus thrombosis and for preoperative mapping of venous structures in patients with neoplasm.
