A dimensão performativa do gesto na prática docente

O presente estudo, de carater ensaistico, discorre, desde um ponto de vista filosofico, sobre o sentido do gesto em geral e na pratica educativa. A analise procede da diferenciacao do sentido do gesto do mero gesto motor em relacao aos gestos figurado ou expressivo a partir da qual se depreende a acepcao propria de gesto a investigacao. Infere-se que a dimensao performativa e, portanto, expressiva do gesto permite criar um espaco de experimentacao e construcao do saber qualitativamente distinto do ordinario, nao regulado por fins de ordem meramente biologica, cognitiva ou instrumental. Essa perspectiva compreende o gesto desde sua dimensao performativa como ato estetico. Descrevem-se e analisam-se os conteudos, os objetos, as condicoes e os efeitos do elemento estetico em face de uma pratica docente performativa. A investigacao e amparada pelas intuicoes de Osman Lins, Walter Benjamin, Hans Ulrich Gumbrecht, Jean Galard, Baldine Saint Girons, entre outros.
Health Care Institutions, Communication, and Physicians' Experience of Managed Care

This study uses the institutional theory of organizational communication (ITOC) to explain physicians' reactions to managed care. ITOC posits that enduring beliefs and practices both transcend and shape particular organizations and organizing. The authors find that physicians' institutional beliefs moderated the negative relationship between managed care medical practice and satisfaction. ITOC also posits that the negotiation of institutional, environmental, organizational, and individual factors occurs through communication. Controlling for these factors, communication with managed care representatives remains significantly and positively related to satisfaction. The results provide support for ITOC and macro approaches to organizational communication research and offer insights for the management of professionals in general and physicians in particular.
Differential Post-Exercise Blood Pressure Responses between Blacks and Caucasians

Post-exercise hypotension (PEH) is widely observed in Caucasians (CA) and is associated with histamine receptors 1- and 2- (H1R and H2R) mediated post-exercise vasodilation. However, it appears that blacks (BL) may not exhibit PEH following aerobic exercise. Hence, this study sought to determine the extent to which BL develop PEH, and the contribution of histamine receptors to PEH (or lack thereof) in this population. Forty-nine (22 BL, 27 CA) young and healthy subjects completed the study. Subjects were randomly assigned to take either a combined H1R and H2R antagonist (fexofenadine and ranitidine) or a control placebo. Supine blood pressure (BP), cardiac output and peripheral vascular resistance measurements were obtained at baseline, as well as at 30 min, 60 min and 90 min after 45 min of treadmill exercise at 70% heart rate reserve. Exercise increased diastolic BP in young BL but not in CA. Post-exercise diastolic BP was also elevated in BL after exercise with histamine receptor blockade. Moreover, H1R and H2R blockade elicited differential responses in stroke volume between BL and CA at rest, and the difference remained following exercise. Our findings show differential BP responses following exercise in BL and CA, and a potential role of histamine receptors in mediating basal and post-exercise stroke volume in BL. The heightened BP and vascular responses to exercise stimulus is consistent with the greater CVD risk in BL.
Sex differences in nutrient‐dependent reproductive ageing

Evolutionary theories of aging predict that fitness‐related traits, including reproductive performance, will senesce because the strength of selection declines with age. Sexual selection theory predicts, however, that male reproductive performance (especially sexual advertisement) will increase with age. In both bodies of theory, diet should mediate age‐dependent changes in reproductive performance. In this study, we show that the sexes exhibit dramatic, qualitative differences in age‐dependent reproductive performance trajectories and patterns of reproductive ageing in the cricket Teleogryllus commodus. In females, fecundity peaked early in adulthood and then declined. In contrast, male sexual advertisement increased across the natural lifespan and only declined well beyond the maximum field lifespan. These sex differences were robust to deviations from sex‐specific dietary requirements. Our results demonstrate that sexual selection can be at least as important as sex‐dependent mortality in shaping the signal of reproductive ageing.
Relationship between Religious Attitude and Happiness among Professional Employees

This article is part of a larger project, which investigated the relationship between religious attitude and subjective well being among Iranian and Indian professional employees. The present article focused on feeling of happiness among Iranian population. The sample consists 1491 employees of which 744 were males and 747 were female. Religious attitude was measured by using Rajmanickam’s Religious Attitude Scale and happiness was measure with The Oxford Happiness Questionnaire by Hills & Argyle. The main findings of the present study were that all the subscales of and total religious attitude were found to be highly correlated with Happiness. Higher the religious attitude, higher was the happiness. Further correlations revealed that higher the happiness more was future life and spirits and spirit world and lastly, happiness though significantly related, less correlated with formal religion aspect of religious attitude.
Memo–RhoA–mDia1 signaling controls microtubules, the actin network, and adhesion site formation in migrating cells

Actin assembly at the cell front drives membrane protrusion and initiates the cell migration cycle. Microtubules (MTs) extend within forward protrusions to sustain cell polarity and promote adhesion site turnover. Memo is an effector of the ErbB2 receptor tyrosine kinase involved in breast carcinoma cell migration. However, its mechanism of action remained unknown. We report in this study that Memo controls ErbB2-regulated MT dynamics by altering the transition frequency between MT growth and shortening phases. Moreover, although Memo-depleted cells can assemble the Rac1-dependent actin meshwork and form lamellipodia, they show defective localization of lamellipodial markers such as alpha-actinin-1 and a reduced number of short-lived adhesion sites underlying the advancing edge of migrating cells. Finally, we demonstrate that Memo is required for the localization of the RhoA guanosine triphosphatase and its effector mDia1 to the plasma membrane and that Memo-RhoA-mDia1 signaling coordinates the organization of the lamellipodial actin network, adhesion site formation, and MT outgrowth within the cell leading edge to sustain cell motility.
Coevolution of Bacteriophage PP01 and Escherichia coli O157:H7 in Continuous Culture

ABSTRACT The interaction between Escherichia coli O157:H7 and its specific bacteriophage PP01 was investigated in chemostat continuous culture. Following the addition of bacteriophage PP01, E. coli O157:H7 cell lysis was observed by over 4 orders of magnitude at a dilution rate of 0.876 h−1 and by 3 orders of magnitude at a lower dilution rate (0.327 h−1). However, the appearance of a series of phage-resistant E. coli isolates, which showed a low efficiency of plating against bacteriophage PP01, led to an increase in the cell concentration in the culture. The colony shape, outer membrane protein expression, and lipopolysaccharide production of each escape mutant were compared. Cessation of major outer membrane protein OmpC production and alteration of lipopolysaccharide composition enabled E. coli O157:H7 to escape PP01 infection. One of the escape mutants of E. coli O157:H7 which formed a mucoid colony (Mu) on Luria-Bertani agar appeared 56 h postincubation at a dilution rate of 0.867 h−1 and persisted until the end of the experiment (∼200 h). Mu mutant cells could coexist with bacteriophage PP01 in batch culture. Concentrations of the Mu cells and bacteriophage PP01 increased together. The appearance of mutant phage, which showed a different host range among the O157:H7 escape mutants than wild-type PP01, was also detected in the chemostat culture. Thus, coevolution of phage and E. coli O157:H7 proceeded as a mutual arms race in chemostat continuous culture.
The Effectiveness of a Multisensory Writing Programme for Improving Cursive Writing Ability in Children with Sensorimotor Difficulties

Children with sensorimotor difficulties experience significant challenges in the ability to write adequately. A single case experimental design with multiple baselines across behaviours was used to evaluate the effectiveness of a multisensory writing programme for improving the cursive writing ability of four children with sensorimotor difficulties. Five distinct letter groups were taught in random order, one group every two weeks. Repeated measurements of writing speed and quality for each letter group were made. Visual analysis indicated that specific letter groups for all of the children changed following intervention. Statistical analysis indicated that quality scores of one child changed significantly while there were no significant changes in overall speed scores. Teacher reports before and following the programme suggest that intervention may have had a positive effect on self-confidence in written output. Further research is needed to evaluate the use of multisensory writing programmes by occupational therapists working with this specific population.
The Role of the Therapeutic Alliance in Psychotherapy and Pharmacotherapy Outcome: Findings in the National Institute of Mental Health Treatment of Depression Collaborative Research Program

The relationship between therapeutic alliance and treatment outcome was examined for depressed outpatients who received interpersonal psychotherapy, cognitive-behavior therapy, imipramine with clinical management, or placebo with clinical management. Clinical raters scored videotapes of early, middle, and late therapy sessions for 225 cases (619 sessions). Outcome was assessed from patients’ and clinical evaluators’ perspectives and from depressive symptomatology. Therapeutic alliance was found to have a significant effect on clinical outcome for both psychotherapies and for active and placebo pharmacotherapy. Ratings of patient contribution to the alliance were significantly related to treatment outcome; ratings of therapist contribution to the alliance and outcome were not significantly linked. These results indicate that the therapeutic alliance is a common factor with significant influence on outcome.
Effect of object orientation on maintainability of software

Maintenance is the set of activities performed after the installation of software. It is well-known that, over the life-time of the software, the maintenance costs can far exceed the development costs. In this paper, we describe an experimental study on the effect of object orientation on maintenance. In particular, we focus on how object orientation fares in maintainability when compared to software designed using function-oriented approaches. For the experiment, a testbed was prepared which consisted of three problems, for each of which the requirement specification, a C implementation and a C++ implementation of an object-oriented design were available. Various maintenance exercises were performed on the the two versions of the projects and different metrics were collected. In these experiments, object-oriented software generally fared better for maintainability
Tissue factor expressed in pituitary adenoma cells contributes to the development of vascular events in pituitary adenomas

Tissue factor (TF) was initially identified as an important factor in the initiation of coagulation. TF has recently been found to be expressed highly in certain types of malignant tumors. It has also been reported to be involved in systemic coagulopathy in cancer patients and in the proliferative and invasive activities of tumor cells. Tissue factor pathway inhibitor (TFPI) is a strong biologic inhibitor of TF. To the authors' knowledge, this is the first study of the expression of TF and TFPI in human pituitary adenoma.
The future history of home care and physician house calls in the United States.

Over the last 20 years, home care has experienced significant change. The home care industry developed into big business and a number of innovative models of home care were developed and evaluated. Although physicians perform many fewer house calls than a half-century ago, there has been a recent revival in house-call training, education, and practice. In addition, telemedicine and other technologies hold great promise for the future of home care. However, the future history of home care will depend mostly on the ability of various stakeholders in the health care system to recognize the value of home care and develop and implement the appropriate incentives to encourage its proper place in the U.S. health care system.

Professional Self-Efficacy as a Predictor of Burnout and Engagement: The Role of Challenge and Hindrance Demands

ABSTRACT. The objective of the current study is to analyze the role of professional self-efficacy as a predictor of psychosocial well-being (i.e., burnout and engagement) following the Social Cognitive Theory of Albert Bandura (1997). Structural Equation Modeling was performed in a sample of secondary school teachers (n = 460) and users of Information and Communication Technology (n = 596). Results show empirical support for the predicting role that professional self-efficacy plays in the perception of challenge (i.e., mental overload) and hindrance demands (i.e., role conflict, lack of control, and lack of social support), which are in turn related to burnout (i.e., erosion process) and engagement (i.e., motivational process). Specifically, employees with more professional self-efficacy will perceive more challenge demands and fewer hindrance demands, and this will in turn relate to more engagement and less burnout. A multi-group analysis showed that the research model was invariant across both samples. Theoretical and practical implications are discussed.
Aggregating vulnerability metrics in enterprise networks using attack graphs

Quantifying security risk is an important and yet difficult task in enterprise network security management. While metrics exist for individual software vulnerabilities, there is currently no standard way of aggregating such metrics. We present a model that can be used to aggregate vulnerability metrics in an enterprise network, producing quantitative metrics that measure the likelihood breaches can occur within a given network configuration. A clear semantic model for this aggregation is an important first step toward a comprehensive network security metric model. We utilize existing work in attack graphs and apply probabilistic reasoning to produce an aggregation that has clear semantics and sound computation. We ensure that shared dependencies between attack paths have a proportional effect on the final calculation. We correctly reason over cycles, ensuring that privileges are evaluated without any self-referencing effect. We introduce additional modeling artifacts in our probabilistic graphical model to capture and account for hidden correlations among exploit steps. The paper shows that a clear semantic model for aggregation is critical in interpreting the results, calibrating the metric model, and explaining insights gained from empirical evaluation. Our approach has been rigorously evaluated using a number of network models, as well as data from production systems.
The Dialectics of the Brazilian Military Regime’s Political Trials

O Brasil tem um dos melhores arquivos de processos legais autoritários do mundo. O arquivo Brasil: Nunca Mais contém todos os processos políticos na justiça militar que recorreram ao Supremo Tribunal Militar entre 1964 e 1979, durante o regime militar. Este artigo usa documentos do arquivo para analisar a interação entre a lógica dos promotores, dos juízes, e dos advogados de defesa nos processos. O artigo enfatiza as contradições na área legal do regime militar, as inconsistências da justiça militar ao julgar o “crime” político de expressão de dissidência ou oposição, e a habilidade dos advogados de defesa em suavizar as aplicações mais severas das leis de segurança nacional.
Assessment of Interpersonal Influences on Adolescents: The Parent and Peer Influence Scale

Peer influence is a common topic of interest for parents, clinicians, and researchers, but results from research on the relative importance of parents’ versus peers’ influence on adolescents and young adults has been contradictory. For example, some research suggests that peer attitudes about school influences future academic aspirations, other research suggests that parents and peers differ on their level of influence based on topic (e.g., parents’ are the primary source of influence about moral issues), and other research suggests that peer-oriented children are a product of parental disregard. A reliable and valid measure of the relative strength of parent versus peer influence could enhance research in this area. As a result, the Parent and Peer Inventory Scale (PPI) was developed, which demonstrates strong reliability as well as face and concurrent validity. The PPI can be used both by researchers to address contradictions in the literature, as well as clinicians seeking to evaluate level of peer influence in a family.
Development of microRNA therapeutics is coming of age

MicroRNAs (miRNAs) play key regulatory roles in diverse biological processes and are frequently dysregulated in human diseases. Thus, miRNAs have emerged as a class of promising targets for therapeutic intervention. Here, we describe the current strategies for therapeutic modulation of miRNAs and provide an update on the development of miRNA‐based therapeutics for the treatment of cancer, cardiovascular disease and hepatitis C virus (HCV) infection.
The Design and Performance of Dynamic and Static Configuration Mechanisms in Component Middleware for Distributed Real-Time and Embedded Systems

QoS-aware component middleware solutions have been shown to be effective in reducing the programming complexity of configuring real-time aspects, with only a small reduction in the run-time performance of those configured aspects. However, many DRE systems (1) must run on real-time platforms that lack key dynamic configuration features, (2) require stringent bounds on system initialization times, (3) have limited storage available at run-time, and yet (4) still require a full range of configuration capabilities for both functional and systemic aspects. Furthermore, there are few studies to date of the design and performance of alternative component middleware configuration mechanisms. This paper makes three contributions to research on QoSaware component middleware for DRE systems. First, it describes the design of static component configuration mechanisms in the Component-Integrated ACE ORB (CIAO), to provide configurability while reducing run-time overhead and footprint, and to avoid features that are not supported by key real-time platforms. Second, this paper presents an empirical comparison of the performance and footprint of dynamic and static configuration mechanisms in CIAO, so that the most suitable configuration mechanisms can be selected according to the specific requirements of each DRE system. Third, it presents an empirical case study that compares CIAO’s static configuration mechanisms to the static configuration mechanisms in PRISM, an avionics domain-specific component middleware solution developed by Boeing.
Heritage-making and political identity

In this essay, I argue that the concept of heritage today, as we have come to understand it through the lens of the politics of recognition and through various tourism-oriented national and global programs of public recognition, contains within itself a number of inherent structural logics — logics which suggest that projects labeled heritage will be pulled in directions which might run counter to the hopes and expectations of those invoking the term. We must, therefore, be cognizant of the fact that at the same moment that heritage discourse enables one mode of conceiving of — and potentially celebrating — historical persons and events, it also disables other forms and modes. We must take seriously what these modes are and what are the implications of their being bracketed. This essay, then, is a call for scholars to consider carefully the fundamental political rationalities at the hearts of our central concepts if we are to understand more fully what is at stake in choosing them.
General Strategy Concepts and the Ecology of Strategy Discourses: A Systemic-Discursive Perspective

Drawing on Wittgenstein, Lyotard and Luhmann the article develops a systemic-discursive perspective on the field of strategy and the respective role of general strategy concepts. The perspective suggests that the field of strategy should not be conceptualized as a unified field but rather as fragmented into a multitude of autonomous discourses. Owing to their autonomy, no transfer of strategy concepts across different discourses is possible. Instead, every single strategy discourse can merely construct its own discourse-specific concepts. Different discourses, however, draw on the same strategy labels, which leads to ‘productive misunderstandings’ (Teubner). On the basis of the particular perspective advanced here, the entire field of strategy is re-described as an ecology of strategy discourses.
6T SRAM design for wide voltage range in 28nm FDSOI

Unique features of the 28nm ultra-thin body and buried oxide (UTBB) FDSOI technology enable the operation of SRAM in a wide voltage range. Minimum operating voltage limitations of a high-density (HD) 6-transistor (6T) SRAM can be overcome by using a single p-well (SPW) bitcell design in FDSOI. Transient simulations of dynamic failure metrics suggest that a HD 6T SPW array with 128 cells per bitline operates down to 0.65V in typical conditions with no assist techniques. In addition, a wide back-bias voltage range enables run-time tradeoffs between the low leakage current in the sleep mode and the short access time in the active mode, making it attractive for high-performance portable applications.
