Country risk, national cultural differences between partners and survival of international joint ventures in Brazil

This article aims to identify the main and interaction effects of two country-level variables, namely national distance and country risk, on the survival of international joint ventures in emerging markets. Research hypotheses predicting the negative impact of national distance and country risk on survival of international joint ventures are formulated in this article. These research hypotheses are examined in a sample of 234 international joint ventures formed in Brazil between 1973 and 2004. These international joint ventures were subjected to an event history analysis over a period of time ranging from 1973 to 2006. The empirical results show that large national cultural differences between local and foreign partners increase the instability of international joint ventures, whereas the survival of these alliances does not seem to be affected either by the economic and political uncertainty of Brazil. Furthermore, the national distance between local and foreign partners has effects on survival that are variable according to the life cycle of international joint ventures. (C) 2007 Elsevier Ltd.

Effect of Ni on Pt/C and PtSn/C prepared by the Pechini method

Different compositions of Pt, PtNi, PtSn, and PtSnNi electrocatalysts supported on carbon Vulcan XC-72 were prepared through thermal decomposition of polymeric precursors. The nanoparticles were characterized by morphological and structural analyses (XRD, TEM, and EDX). XRD results revealed a face-centered cubic structure for platinum, and there was evidence that Ni and Sn atoms are incorporated into the Pt structure. The electrochemical investigation was carried out in slightly acidic medium (H(2)SO(4) 0.05 mol L(-1)), in the absence and in the presence of ethanol. Addition of Ni to Pt/C and PtSn/C catalysts significantly shifted the onset of ethanol and CO oxidations toward lower potentials, thus enhancing the catalytic activity, especially in the case of the ternary PtSnNi/C composition. Electrolysis of ethanol solutions at 0.4 V us. RHE allowed for determination of acetaldehyde and acetic acid as the reaction products, as detected by HPLC analysis. Due to the high concentration of ethanol employed in the electrolysis experiments (1.0 mol L(-1)), no formation of CO(2) was observed. Copyright (C) 2010, Hydrogen Energy Publications, LLC.

Francoist Primary education: the schoolbook as an instrument of child indoctrination

The Francoist rule, mainly in its first decades, exerted a strong control upon education, which was left in the hands of the Catholic nationalist. Innumerous children`s schoolbooks were published driven by strong patriotic and religious bias. The authors aimed to shape the children`s minds based on the premises that supported the regimen: authority, hierarchy, order, abeyance, fear and devotion to God and the leader Francisco Franco. This paper analyzes the content of the elementary education books and shows how they were important instruments of child indoctrination marked by intolerance. The content and the images of the books contributed to construct an excluding national identity based on a heightened Catholic patriotism, stimulated heroism, martyrdom, child sacrifice, and hatred for the enemies of the religion and of ""mother Spain"".

Sweeping democracy: considerations on the political relations between Janio Quadros and the National Congress

This article examines the relation between President Janio Quadros and the National Congress during the early 1960`s. Based on the analysis of the discourse of these figures, it proposes that Quadros maneuvered to diminish the legitimacy of the Congress in the public opinion, thus disrespecting its constitutional competencies. Consequently, it shows that not only did the Congress structure political mechanisms in an attempt to recover its credibility with society, but also that this dispute and its results had important effects on President Joao Goulart`s administration and even on the 1964 military coup.

Alcohol use disorders in patients with obsessive-compulsive disorder: The importance of appropriate dual-diagnosis

Objective: To evaluate the prevalence and clinical associated factors of alcohol use disorders (AUD) comorbidity in a large clinical sample of patients with obsessive-compulsive disorder (OCD). Methods: A cross-sectional study including 630 DSM-IV OCD patients from seven Brazilian university services, comparing patients with and without AUD comorbidity. The instruments of assessment used were a demographic and clinical questionnaire including evaluation of suicidal thoughts and acts and psychiatric treatment, the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I), the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Brown Assessment of Beliefs Scale, the Beck Depression and Anxiety Inventories and the Clinical Global Impression Scale. Current or past alcohol and other psychoactive substances use, abuse and dependence were assessed using the SCID-I (section E) and corroborated by medical and familial history questionnaires. Results: Forty-seven patients (7.5%) presented AUD comorbidity. Compared to OCD patients without this comorbidity they were more likely to be men, to have received previous psychiatric treatment, to present: lifetime suicidal thoughts and attempts and to have higher scores in the hoarding dimension. They also presented higher comorbidity with generalized anxiety and somatization disorders, and compulsive sexual behavior. Substance use was related to the appearance of the first O.C. symptoms and symptom amelioration. Conclusions: Although uncommon among OCD treatment seeking samples, AUD comorbidity has specific clinical features, such as increased risk for suicidality, which deserve special attention from mental health professionals. Future studies focused on the development of specific interventions for these patients are warranted. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

The policy cycle and vernacular globalization: a case study of the creation of Vietnam National University - Hochiminh City

This article examines the policy cycle and vernacular globalization in the context of higher education reform in Vietnam. Through an analysis of the development of the Vietnam National University - Hochiminh City as part of the post-1986 reconstruction of Vietnamese higher education, the article considers the complex interrelationship between globalized policy discourses, national interests and history in Vietnam, and the specific politics of policy implementation within one institution. Vietnam National University - Hochiminh City was created through an amalgamation of a number of smaller universities, and against the backdrop of social and economic restructuring aimed at promoting industrialization and a market orientation within socialist governance. The article reveals the dynamic tension between these local and global influences on higher education policy and practice, and more specifically, the dilemmas associated with top-down policy implementation when a new organization consists of older organizations with powerful provenance and reputations. In so doing the article demonstrates the necessity to globalize policy theory.

The microstructure of mechanically alloyed MoSi2 with Ni and Al additions

The effect of Ni and Al additions on grain boundary silica in mechanically alloyed and hot isostatically pressed (HTPed) MoSi2 was investigated. Mechanical alloying Mo and Si in the absence of Al produced finely dispersed silica within a fine grained structure. Mechanically alloyed and HIPed Mo and Si with Ni and Al partially transformed the silica to crystalline oxide phases, including Al2O3. An improvement in high temperature properties is not expected due to the retention of a grain boundary silica film. Rapid grain growth resulted during HIPing, possibly due to the formation of a Ni/Fe/Al liquid phase.

Electron paramagnetic resonance of Ni(II) doped tris(ethylenediamine)zinc(II) dinitrate

Variable temperature electron paramagnetic resonance spectra of tris(ethylenediamine)zinc(II) dinitrate single crystals doped with NI(II) have been measured. The host crystal undergoes a trigonal to monoclinic phase transition at 146 K. Above the transition temperature the zero field splitting tensor is axially symmetric with D = -0.831 cm(-1) and below it becomes rhombic with D = -0.785 cm(-1), E = -0.088 cm(-1). The low temperature spectrum is characterised by the pattern repeating every 60 degrees when the crystal is rotated about the high temperature c axis. The analysis shows that the Zn(II) site retains a C-2 symmetry axis and that the distortion away from the D-3 site symmetry observed for high temperatures is small, the principal axes being tilted by 2.6 degrees. This implies that the phase transition involves the flipping of the C-C backbone in one of the ethylenediamine ligands of the complex, resulting in a A delta delta delta to Lambda delta delta lambda type conformational change.

Gas-surface interactions in the thermal and sub-thermal regime: A molecular dynamics study

Molecular dynamics simulations are used to study the interaction of low-energy Ar atoms with the Ni(001) surface, Angular scattering distributions, in and out of the plane of incidence, are investigated as a function of incident energy, angles of incidence, crystallographic orientation of the incident beam and surface temperature. The results show a clear transition to the structure scattering regime at around 2 eV. However, at lower energies, two sub-regimes are revealed by the simulations, Far energies up to 250 meV, scattering is mainly diffuse, and significant trapping on the surface is observed, At energies above this level, lobular patterns start to form and trapping decreases with the increase in energy, Generally, there is a weak temperature dependence, but variations in the angle of incidence and/or changes in the crystallographic direction, generate significant changes in the scattering patterns.

A cross-national comparison of Australian and Canadian supervisors' attributional and evaluative responses to subordinate performance

In a program of laboratory and field research over the last decade, the author has replicated and extended the attribution model of leadership (Green & Mitchell, 1979). This paper reports a cross-national test of the model, in which 172 Australian and 144 Canadian work supervisors' recalled their attributional and evaluative responses to high and low levels of subordinate performance. It was expected that the supervisors' responses would conform to the predictions established in the earlier studies, but that there would be key differences across the cultures. In particular, Australians were expected to endorse more internal attributions for subordinate performance than Canadians, and to focus more on individual characteristics in evaluating performance. Results supported the model's robustness and the hypothesised cross-national differences. The implications of these results are discussed in terms of crosscultural research opportunities, and the need to take account of small but potentially important differences in supervisory styles across cultures.

National audit of anaesthesia for major abdominal surgery

A postal survey was conducted of all hospitals in Australia known to have a department of anaesthesia and an intensive care or high dependency unit. Each hospital was asked to report the anaesthetic and postoperative analgesic techniques used for the last ten cases of four common major surgical procedures-aorto-femoral bypass, repair of an abdominal aortic aneurysm, hemicolectomy and anterior resection of the rectum. Half of 76 hospitals sent a survey form completed and returned it. Responding hospitals were larger on average, than non-responding ones, but otherwise typical of them in terms of university affiliation and metropolitan versus rural location. For each of the procedures studied the proportion of cases in which epidural block was used intra- or postoperatively varied from 0% to 100%. Depending on the procedure, between 65% and 85% of hospitals used epidural block sometimes, with between 10% and 90% of patients in these hospitals being managed with this technique. There is wide variation in the use of epidural block, intra- and postoperatively, in Australia, variation that is unlikely to be explained by systematic differences between institutions in the patients seen or their suitability for one or other technique. This pattern of practice mirrors the lack of agreement about the proper place for epidural techniques evident in the recent literature. There is a widespread belief among clinicians that this is a question of great importance. Accordingly, we believe that anaesthetists and surgeons share an ethical responsibility to enter suitable patients in an appropriately designed randomized controlled trial in order to resolve this question.

Factors affecting management decisions in rectal cancer in clinical practice: results from a national survey

Management of rectal cancer has become increasingly complex and a multidisciplinary approach is considered of key importance for improving outcomes. A national survey among specialists involved in this multidisciplinary setting was performed. A web-based survey containing 11 questions regarding rectal cancer management was sent to surgeons and medical oncologists registered by their corresponding societies as members. Statistical analysis was performed using the chi-square and Fisher`s exact tests for all categorical variables according to response to individual questions. Multivariate analysis was performed using Cox`s logistic regression. Overall, 418 email recipients responded the survey. Local staging was performed without either magnetic resonance imaging or endorectal ultrasound by 64% of responders. Seventy-two percent considered that final management decision should be made after neoadjuvant chemoradiation therapy. Additionally, 46% considered that an alternative procedure (local excision or observation) was appropriate in a patient with a complete clinical response. Colorectal surgeons were more frequently in favor of longer intervals after completion of chemoradiation therapy (P = 0.001) and of alternative management procedures after a complete clinical response (P = 0.02). After multivariate analysis, the choice of a watch and wait approach after a complete clinical response following neoadjuvant chemoradiation therapy was significantly more frequent among surgeons (OR 3.5, 95% CI 1.8-7.1). Surgeons seem to be more in favor of tailoring management of rectal cancer according to tumor response after neoadjuvant chemoradiation therapy, with longer intervals after chemoradiation therapy, decisions about treatment strategy being made after chemoradiation therapy instead of before, and the use of alternative surgical procedures after a complete clinical response following neoadjuvant therapy.

Effects of oxide promoters on metal dispersion and metal-support interactions in Ni catalysts supported on activated carbon

Various oxide-promoted Ni catalysts supported on activated carbon were prepared, and the effect of promoters on the surface structure and properties of Ni catalysts was studied. Physical adsorption (Na adsorption), thermogravimetric analysis (TGA), temperature-programmed desorption (TPD), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were used to characterize the catalysts. It is found that nickel is fairly uniformly distributed in the pores of the carbon support. Addition of promoters produces a more homogeneous distribution of nickel ion in carbon. However, distributions of promoters in the pores are varying. Addition of promoters increases the dispersion of nickel in carbon. Promoters also change the interaction between the carbon and Ni, resulting in significantly different behaviors of catalysts under various environments. CaO and MgO promoters improve the reactivity of nickel catalysts with O-2 but retard the interaction between nickel oxide and carbon. La2O3 shows some inhibiting effect on the interactions between nickel oxide and oxygen as well as carbon.

Gender equality and participation in housework: A cross-national perspective

This paper examines men's and women's participation in housework in the United States, Sweden, Norway, Canada and Australia. While there has been considerable research into the factors relating to the division of housework between husbands and wives within countries, very little research has examined the way in which housework patterns vary across countries. The results show that women continue to undertake the bulk of domestic labor in all five countries, and that the factors determining men's and women's participation in housework do not vary markedly across countries. This suggests that variations across countries in levels of gender equality at a broader level have only very limited effects on levels of gender equality in the home.
