Mediate evaluation of replicating a Training Program in Nonverbal Communication in Gerontology

OBJECTIVE Replicating the training program in non-verbal communication based on the theoretical framework of interpersonal communication; non-verbal coding, valuing the aging aspects in the perspective of active aging, checking its current relevance through the content assimilation index after 90 days (mediate) of its application. METHOD A descriptive and exploratory field study was conducted in three hospitals under direct administration of the state of São Paulo that caters exclusively to Unified Health System (SUS) patients. The training lasted 12 hours divided in three meetings, applied to 102 health professionals. RESULTS Revealed very satisfactory and satisfactory mediate content assimilation index in 82.9%. CONCLUSION The program replication proved to be relevant and updated the setting of hospital services, while remaining efficient for healthcare professionals.

Factors influencing Intensive Care Units nurses in end-of-life decisions

OBJECTIVETo identify the factors that influence the Intensive Care Unit nurse in the decision-making process in end-of-life situations.METHODEthnographic case study, which used the theoretical framework of medical anthropology. Data were collected through semi-structured interviews with 10 nurses.RESULTSThe inductive thematic analysis enabled us to identify four themes:The cultural context of the Intensive Care Unit: decision-making in situations of end-of-life; Beliefs and subjectivity of care in end-of-life situations; Professional experience and context characteristics of end-of-life care situations; and Humanization practices in end-of-life situations: the patient and family centered care.CONCLUSIONProfessional maturity, the ability to transmit information and the ability to negotiate are directly related to the inclusion of nurses in the decision-making process.

Common law and civil law as pro-market adaptations

We argue that in the development of the Western legal system, cognitive departures are themain determinant of the optimal degree of judicial rule-making. Judicial discretion, seen here as the main distinguishing feature between both legal systems, is introduced in civil law jurisdictions to protect, rather than to limit, freedom of contract against potential judicial backlash. Such protection was unnecessary in common law countries, where free-market relations enjoyed safer judicial ground mainly due to their relatively gradual evolution, their reliance on practitioners as judges, and the earlier development of institutional checks and balances that supported private property rights. In our framework, differences in costs and benefits associated with self-interest and lack of information require a cognitive failure to be active.

Portfolio choice and the effects of liquidity

This paper shows how to introduce liquidity into the well known mean-variance framework of portfolio selection. Either by estimating mean-variance liquidity constrained frontiers or directly estimating optimal portfolios for alternative levels of risk aversion and preference for liquidity, we obtain strong effects of liquidity on optimal portfolio selection. In particular, portfolio performance, measured by the Sharpe ratio relative to the tangency portfolio, varies significantly with liquidity. Moreover, although mean-variance performance becomes clearly worse, the levels of liquidity onoptimal portfolios obtained when there is a positive preference for liquidity are much lower than on those optimal portfolios where investors show no sign of preference for liquidity.

On the cultural transmission of corruption

We provide a cultural explanation to the phenomenon of corruption in the framework of an overlapping generations model with intergenerational transmissionof values. We show that the economy has two steady states with different levels of corruption. The driving force in the equilibrium selection process is the education effort exerted by parents which depends on the distribution of ethics in the population and on expectations about future policies. We propose some policy interventions which via parents' efforts have long-lasting effects on corruption and show the success of intensive education campaigns. Educating the young is a key element in reducing corruption successfully.

A comment on the Nash program and the theory of implementation

The mechanisms in the Nash program for cooperative games are madecompatible with the framework of the theory of implementation. This is donethrough a reinterpretation of the characteristic function that avoids feasibilityproblems, thereby allowing an analysis that focuses exclusively on the payoff space. In this framework, we show that the core is the only majorcooperative solution that is Maskin monotonic. Thus, implementation of mostcooperative solutions must rely on refinements of the Nash equilibrium concept(like most papers in the Nash program do). Finally, the mechanisms in theNash program are adapted into the model.

Employment consequences of restrictive permanent contracts: Evidence from Spanish labor market reforms

Temporary employment contracts allowing unrestricted dismissals wereintroduced in Spain in 1984 and quickly came to account for most new jobs.As a result, temporary employment increased from around 10% in themid-eighties to more than 30% in the early nineties. In 1997, however,the Spanish government attempted to reduce the incidence of temporaryemployment by reducing payroll taxes and dismissal costs for permanentcontracts. In this paper, we use individual data from the Spanish LaborForce Survey to estimate the effects of reduced payroll taxes anddismissal costs on the distribution of employment and worker flows. Weexploit the fact that recent reforms apply only to certain demographicgroups to set up a natural experiment research design that can be usedto study the effects of contract regulations. Our results show that thereduction of payroll taxes and dismissal costs increased the employmentof young workers on permanent contracts, although the effects for youngwomen are not always significant. Results for older workers showinsignificant effects. The results suggest a moderately elastic responseof permanent employment to non-wage labor costs for young men. We alsofind positive effects on the transitions from unemployment and temporaryemployment into permanent employment for young and older workers, althoughthe effects for older workers are not always significant. On the otherhand, transitions from permanent employment to non-employment increasedonly for older men, suggesting that the reform had little effect ondismissals.

EORTC-ROG expert opinion: radiotherapy volume and treatment guidelines for neoadjuvant radiation of adenocarcinomas of the gastroesophageal junction and the stomach.

PURPOSE: The Gastro-Intestinal Working Party of the EORTC Radiation Oncology Group (GIWP-ROG) developed guidelines for target volume definition in neoadjuvant radiation of adenocarcinomas of the gastroesophageal junction (GEJ) and the stomach. METHODS AND MATERIALS: Guidelines about the definition of the clinical target volume (CTV) are based on a systematic literature review of the location and frequency of local recurrences and lymph node involvement in adenocarcinomas of the GEJ and the stomach. Therefore, MEDLINE was searched up to August 2008. Guidelines concerning prescription, planning and treatment delivery are based on a consensus between the members of the GIWP-ROG. RESULTS: In order to support a curative resection of GEJ and gastric cancer, an individualized preoperative treatment volume based on tumour location has to include the primary tumour and the draining regional lymph nodes area. Therefore we recommend to use the 2nd English Edition of the Japanese Classification of Gastric Carcinoma of the Japanese Gastric Cancer Association which developed the concept of assigning tumours of the GEJ and the stomach to anatomically defined sub-sites corresponding respectively to a distinct lymphatic spread pattern. CONCLUSION: The GIWP-ROG defined guidelines for preoperative irradiation of adenocarcinomas of the GEJ and the stomach to reduce variability in the framework of future clinical trials.

Mineralogical, petrographic and geochemical characterisation of white and coloured Iberian marbles in the context of the provenancing of some artefacts from Thamusida (Kenitra, Morocco)

A multi-analytical study has been carried out on a collection of white and coloured Iberian marbles. A total of 135 marble specimens were collected in Spain and Portugal from the Betic chain (Alhaurin de la Torre, Mijas, Macael), Ossa Morena (Alconera, Almaden de la Plata and Viana do Alentejo), and the Estremoz Anticline (Bencatel, Borba and Estremoz) areas. X-ray diffractometry and carbon and oxygen stable isotope analysis were carried out on these samples; 38 samples were also investigated by optical and scanning electron microscopy. The results provide a set of diagnostic parameters that allow discriminating the sampled marble quarries. The carbonate minerals composition is distinctive for the Mijas and Alhaurin de la Torre marbles; the isotopic analysis allows discriminating also between these two dolomitic marble quarries. The Ossa Morena and Estremoz Anticline marbles share a similar stable isotope composition; the accessory mineral content, the maximum grain size (MGS) and the fabric are particularly useful in the distinction between them. In the framework of archaeometric provenance studies on Thamusida (Kenitra, Morocco) Roman marble artefacts, a specific comparison between this new Iberian database and archaeological findings has been carried out. The hypothesis of commercial exchanges between the Iberian regions and Roman Morocco is supported by the results of the provenance study, which suggested the Almaden de la Plata and Mijas quarries as possible sources of raw materials for the production of archaeological artefacts.

Synergistic effect of calcitriol and interferon-α on hepatitis C virus replication in vitro

Background and aims: V itamin D is an important modulator o fnumerous c ellular processes, including innate and adaptive immunepathways. A recent large-scale genetic validation study performed withinthe framework of the Swiss Hepatitis C Cohort S tudy has demonstratedan association between t he 1α-hydroxylase promoter single nucleotidepolymorphism CYP27B1-1260 rs10877012 and sustained virologicresponse (SVR) after pegylated interferon-α ( PEG-IFN-α) plus ribavirintreatment of c hronic hepatitis C in patients w ith a p oor-response IL28Bgenotype. This suggests an intrinsic role o f vitamin D signaling in theresponse t o treatment of chronic hepatitis C, especially in patients withlimited sensitivity to IFN-α. In the present study, we investigated theeffect of 1,25-(OH)2 v itamin D3 (calcitriol) alone or in combination withIFN-α on the hepatitis C virus (HCV) life cycle in vitro.Methods: H uh-7.5 cells harboring Con1- or JFH-1-derived HCVreplicons or cell culture-derived HCV were exposed to 0.1-100 nMcalcitriol ± 1 -100 IU/ml IFN-α. The effect on HCV RNA replication andviral particle production was investigated by quantitative r eal-time PCR,immunoblot analyses, and infectivity titration analyses. The expression ofinterferon-stimulated genes (ISGs) and of calcitriol target genes wasassessed by quantitative real-time PCR.Results: Calcitriol had no relevant effect on the viability of Huh-7.5 cells.Calcitriol strongly induced and repressed the expression of the calcitrioltarget genes CYP24A1 and CCNC, respectively, confirming that Huh-7.5cells c an respond to c alcitriol signaling. P hysiological doses of calcitrioldid not significantly a ffect HCV RNA replication or i nfectious particleproduction in vitro, and calcitriol alone h ad no significant effect on theexpression of several ISGs. However, calcitriol in combination with IFN-αsubstantially increased the expression of ISGs compared to IFN-α alone.In addition, calcitriol plus IFN-α s ynergistically inhibited HCV RNAreplication.Conclusions: C alcitriol at physiological concentrations and IFN-α a ctsynergistically on the expression of I SGs and HCV RNA replication i nvitro. Experiments exploring the underlying mechanisms are underway.

Market institutions and judicial rulemaking

Assuming that the degree of discretion granted to judges was the main distinguishing feature between common and civil law until the 19th century, we argue that constraining judicial discretion was instrumental in protecting freedom of contract and developing the market order in civil law. We test this hypothesis by analyzing the history of Western law. In England, a unique institutional balance between the Crown and the Parliament guaranteed private property and prompted the gradual evolution towards a legal framework that facilitated market relationships, a process that was supported by the English judiciary. On the Continent, however, legal constraints on the market were suppressed in a top-down fashion by the founders of the liberal state, often against the will of the incumbent judiciary. Constraining judicial discretion there was essential for enforcing freedom of contract and establishing the legal order of the market economy. In line with this evidence, our selection hypothesis casts doubts on the normative interpretation of empirical results that proclaim the superiority of one legal system over another, disregarding the local conditions and institutional interdependencies on which each legal system was grounded.

A note on the Malliavin differentiability of the Heston volatility

We show that the Heston volatility or equivalently the Cox-Ingersoll-Ross process is Malliavin differentiable and give an explicit expression for the derivative. This result assures the applicability of Malliavin calculus in the framework of the Heston stochastic volatility model and the Cox-Ingersoll-Ross model for interest rates.

New perspective on the study of the authority relationship: Integrating individual and societal level research.

The concept of authority crosses many social sciences, but there is a lack of common taxonomy and definitions on this topic. The aims of this review are: (1) to define the basic characteristics of the authority relationship, reaching a definition suitable for the different domains of social psychology and social sciences; (2) to bridge the gap between individual and societal levels of explanation concerning the authority relationship, by proposing an interpretation within the framework of social representations. The authority relationship can be conceived as a negotiation of meanings and it is closely linked to shared value orientation and the attribution of meanings negotiated within a society. We assume that the authority relationship is socially constructed and represents both a shared representation of society and a normative principle of social life. A multidisciplinary approach is adopted, crossing definitions and studies provided in sociology, political science, law and social psychology.

Constant fluctuating asymmetry but not directional asymmetry along the geographic distribution of Drosophila antonietae (Diptera, Drosophilidae)

ABSTRACT The population dynamics of a species tends to change from the core to the periphery of its distribution. Therefore, one could expect peripheral populations to be subject to a higher level of stress than more central populations (the center–periphery hypothesis) and consequently should present a higher level of fluctuating asymmetry. To test these predictions we study asymmetry in wing shape of five populations of Drosophila antonietae collected throughout the distribution of the species using fluctuating asymmetry as a proxy for developmental instability. More specifically, we addressed the following questions: (1) what types of asymmetry occur in populations of D. antonietae? (2) Does the level of fluctuating asymmetry vary among populations? (3) Does peripheral populations have a higher fluctuating asymmetry level than central populations? We used 12 anatomical landmarks to quantify patterns of asymmetry in wing shape in five populations of D. antonietae within the framework of geometric morphometrics. Net asymmetry – a composite measure of directional asymmetry + fluctuating asymmetry – varied significantly among populations. However, once net asymmetry of each population is decomposed into directional asymmetry and fluctuating asymmetry, most of the variation in asymmetry was explained by directional asymmetry alone, suggesting that populations of D. antonietae have the same magnitude of fluctuating asymmetry throughout the geographical distribution of the species. We hypothesize that larval development in rotting cladodes might play an important role in explaining our results. In addition, our study underscores the importance of understanding the interplay between the biology of a species and its geographical patterns of asymmetry.

André spectral sequences for Baues-Wirsching cohomology of categories

We construct spectral sequences in the framework of Baues-Wirsching cohomology and homology for functors between small categories and analyze particular cases including Grothendieck fibrations. We also give applications to more classical cohomology and homology theories including Hochschild-Mitchell cohomology and those studied before by Watts, Roos, Quillen and others
