The influence of pre-departure training on expatriate adjustment: an empirical investigation with portuguese international assignees

This chapter examines the cross-cultural influence of training on the adjustment of international assignees. We focus on the pre-departure training (PDT) before an international assignment. It is an important topic because in the globalized world of today more and more expatriations are needed. The absence of PDT may generate the failure of the expatriation experience. Companies may neglect PDT due to cost reduction practices and ignorance of the need for it. Data were collected through semi-structured interviews to 42 Portuguese international assignees and 18 organizational representatives from nine Portuguese companies. The results suggest that companies should develop PDT programs, particularly when the cultural distance to the host country is bigger and when there is no previous experience of expatriation to that country in the company. The study is original because it details in depth the methods of PDT, its problems, and consequences. Some limitations linked to the research design and detailed in the conclusion should be overcome in future studies.

Privatization in an international mixed duopoly with environmental taxes

We study the effects of environmental and trade policies in an international duopoly serving two countries, with pollution abatement. This analysis is done in both mixed and privatized markets. The model has two stages: First, governments choose environmental taxes and import tariffs, simultaneously; then, the firms compete in the market by choosing output levels for the domestic market and to export and also abatement levels.

China's space program : a new tool for PRC "soft power" in international relations?

When China launched an anti-satellite (ASAT) weapon in January 2007 to destroy one of its inactive weather satellites, most reactions from academics and U.S. space experts focused on a potential military “space race” between the United States and China. Overlooked, however, is China’s growing role as global competitor on the non-military side of space. China’s space program goes far beyond military counterspace applications and manifests manned space aspirations, including lunar exploration. Its pursuit of both commercial and scientific international space ventures constitutes a small, yet growing, percentage of the global space launch and related satellite service industry. It also highlights China’s willingness to cooperate with nations far away from Asia for political and strategic purposes. These partnerships may constitute a challenge to the United States and enhance China’s “soft power” among key American allies and even in some regions traditionally dominated by U.S. influence (e.g., Latin America and Africa). Thus, an appropriate U.S. response may not lie in a “hard power” counterspace effort but instead in a revival of U.S. space outreach of the past, as well as implementation of more business-friendly export control policies.

The visual image in Epiphanic Short History

The visual image is a fundamental component of epiphany, stressing its immediacy and vividness, corresponding to the enargeia of the traditional ekphrasis and also playing with cultural and social meanings. Morris Beja in his seminal book Epiphany in the Modern Novel, draws our attention to the distinction made by Joyce between the epiphany originated in a common object, in a discourse or gesture and the one arising in “a memorable phase of the mind itself”. This type materializes in the “dream-epiphany” and in the epiphany based in memory. On the other hand, Robert Langbaum in his study of the epiphanic mode, suggests that the category of “visionary epiphany” could account for the modern effect of an internally glowing vision like Blake’s “The Tyger”, which projects the vitality of a real tyger. The short story, whose length renders it a fitting genre for the use of different types of epiphany, has dealt with the impact of the visual image in this technique, to convey different effects and different aesthetic aims. This paper will present some examples of this occurrence in short stories of authors in whose work epiphany is a fundamental concept and literary technique: Walter Pater, Joseph Conrad, K. Mansfield, Clarice Lispector. Pater’s “imaginary portraits” concentrate on “priviledged moments” of the lives of the characters depicting their impressions through pictorial language; Conrad tries to show “moments of awakening” that can be remembered by the eye; Mansfield suggests that epiphany, the “glimpse”, should replace plot as an internal ordering principle of her impressionist short-stories; in C. Lispector the visualization of some situations is so aggressive that it causes nausea and a radical revelation on the protagonist’s.

Expatriates’ influence on knowledge sharing: an empirical study with International portuguese companies

Despite the abundant literature in knowledge management, few empirical studies have explored knowledge management in connection with international assignees. This phenomenon has a special relevance in the Portuguese context, since (a) there are no empirical studies concerning this issue that involves international Portuguese companies; (b) the national business reality is incipient as far as internationalisation is concerned, and; (c) the organisational and national culture presents characteristics that are distinctive from the most highly studied contexts (e.g., Asia, USA, Scandinavian countries, Spain, France, The Netherlands, Germany, England and Russia). We examine the role of expatriates in transfer and knowledge sharing within the Portuguese companies with operations abroad. We focus specifically on expatriates’ role on knowledge sharing connected to international Portuguese companies and our findings take into account organizational representatives’ and expatriates’ perspectives. Using a comparative case study approach, we examine how three main dimensions influence the role of expatriates in knowledge sharing among headquarters and their subsidiaries (types of international assignment, reasons for using expatriation and international assignment characteristics). Data were collected using semi‐structured interviews to 30 Portuguese repatriates and 14 organizational representatives from seven Portuguese companies. The findings suggest that the reasons that lead Portuguese companies to expatriating employees are connected to: (1) business expansion needs; (2) control of international operations and; (3) transfer and knowledge sharing. Our study also shows that Portuguese companies use international assignments in order to positively respond to the increasingly decaying domestic market in the economic areas in which they operate. Evidence also reveals that expatriation is seen as a strategy to fulfill main organizational objectives through their expatriates (e.g., business internationalization, improvement of the coordination and control level of the units/subsidiaries abroad, replication of aspects of the home base, development and incorporation of new organizational techniques and processes). We also conclude that Portuguese companies have developed an International Human Resources Management strategy, based on an ethnocentric approach, typically associated with companies in early stages of internationalization, i.e., the authority and decision making are centered in the home base. Expatriates have a central role in transmitting culture and technical knowledge from company’s headquarters to the company’s branches. Based on the findings, the article will discuss in detail the main theoretical and managerial implications. Suggestions for further research will also be presented.

Exploring why portuguese companies expatriate, and portuguese expatriates accept international assignments

This study explores (1) the reasons that lead Portuguese companies to use expatriates and (2) the motivations that led the repatriates to accepting an international assignment. Semistructured interviews were carried out on 44 individuals (14 responsible for organizational management of the expatriates and 30 repatriates), in seven international companies based in Portugal, and analysis of the thematic content was conducted for data processing. Results suggest that the reasons that lead Portuguese companies to expatriating employees are connected to business needs and the control of international operations, while individual motivations are linked to personal and professional ambition, the will to serve the company and organizational pressure. We concluded that Portuguese companies, like most European companies, seem to develop a strategy of International Human Resources Management (IHRM) according to an ethnocentric approach, characteristic to companies in early stages of internationalization. Similarly, the main motivations of Portuguese repatriates are identical to those of other expatriates, though the will to serve the company seems to be more valued by Portuguese repatriates than by expatriates from other countries.

International Expectations: ICW - Prelúdio para o CNM

Neste artigo são abordadas as primeiras diligências internacionais para se formar o CNMP, Conselho Nacional das Mulheres Portuguesas. Procurámos identificar as figuras que estiveram envolvidas nesses contactos iniciais, delineando o relacionamento com a Rainha Sr.ª D. Amélia por parte de quem esteve envolvido. Tempo será ainda de apurar as razões do insucesso. Este estudo assinala uma antecipação em cerca de 10 anos no historial do CNMP, relevante pelas pessoas envolvidas, pelas relações com o feminismo internacional, com particular impacto pois sinaliza o sentido em que o mesmo ocorreu. A iniciativa partiu do ICW «International Council of Women» para Portugal, como acontecera antes estando na génese de outros Conselhos congé

Embolização das artérias prostáticas no tratamento da hiperplasia benigna da próstata : estudo anátomo-clínico

Resumo: A hiperplasia benigna da próstata (HBP) tem elevada prevalência nos homens entre os 50 e 79 anos de idade, sendo ubiquitária com o envelhecimento. Devido à significativa morbi-mortalidade associada aos tratamentos médicos e cirúrgicos currentemente disponíveis, são necessárias novas tecnologias para melhorar os resultados e minimizar o desconforto dos doentes. Recentemente, estudos preliminares de experimentação animal e em 3 doentes tratados, sugeriram a embolização arterial prostática selectiva (EAPS) como hipótese terapêutica para a HBP. Decidimos investigar se a EAPS poderia ser um procedimento bem sucedido no tratamento da HBP gravemente sintomática. Para tal realizámos um estudo anátomo-radiológico e clínico em 63 doentes com recurso a uma terapêutica inovadora minimamente invasiva guiada pela imagem. Avaliámos 126 hemipélvis com recurso a Angio-RM, Angio-TC e Angiografia Digital de Subtracção, com o intuito de definir os padrões básicos de bifurcação das artérias ilíacas internas até agora apenas descritos em estudos cadavéricos. Estudámos ainda o suprimento vascular arterial prostático, identificando: 1 as artérias prostáticas; 2 origem e direcção; 3 os ramos intra-prostáticos; 4 anastomoses com outras artérias. Em relação aos resultados anatómicos, identificámos 181 artérias prostáticas, já que em 43.7% das hemipélvis existiam dois pedículos arteriais prostáticos com origens independentes. A origem mais frequente foi a artéria pudenda interna (39.7%), seguida do tronco comum glúteo-pudendo (21%) e da artéria vesical superior (18.2%). Origens menos frequentes foram a artéria obturadora (12.1%), as artérias glúteas inferior (3.9%)ou superior (1.7%), ramos rectais provenientes da artéria mesentérica inferior (1.7%) e a artéria pudenda acessória (1.7%). Identificaram-se anastomoses com as artérias adjacentes em 57.9% dos casos: com a terminação da artéria pudenda interna (41.6%),artérias prostáticas contra-laterais (18.2%) e homo-laterais (11.7%), com ramos rectais (15.6%) e com artérias vesicais (12.9%). Em relação ao estudo clínico tratámos 63 doentes (idades compreendidas entre 52 - 82 anos, média 69.5 anos) com HBP gravemente sintomática refractária à terapêutica médica há mais de 6 meses. Foi possível avaliação após o tratamento em 37 doentes: média de seguimento de 4.7 meses (variando entre 1 e 12 meses). A EAPS unilateral foi possível em todos os doentes, com embolização bilateral em 73% dos casos. A embolização bilateral não foi possível em 27% dos casos devido a tortuosidade, alterações ateroescleróticas e pequeno calibre das artérias ilíacas e/ou prostáticas. Em média houve uma melhoria do International Prostate Symptom Score (IPSS) de 10.8 pontos, da QoL de 1.5 pontos e do Internationl Index of Erectile Function (IIEF) de 2.1 pontos. Houve uma redução média do PSA de 30% (2.4 ng/mL), um aumento do pico de fluxo urinário (Qmax) de 3.1 - 3.85 mL/s e uma redução média do volume prostático de 21% (18.5 mL). Registou-se uma complicação major: pequena área de isquémia da parede vesical tratada cirurgicamente. Em 75% dos doentes tratados obteve-se sucesso clínico com franca melhoria dos sintomas, enquanto 25% dos doentes foram considerados insucesso clínico por se ter registado uma fraca ou ausente melhoria sintomática após a embolização. Os restantes doentes tratados estão sob controlo evolutivo, pararam toda a medicação prostática, sem qualquer caso de disfunção sexual associada com o tratamento. Este trabalho constitui o primeiro estudo anatómico descritivo in vivo das artérias prostáticas, conseguido devido à utilização de técnicas de imagem nunca usadas para este fim. O uso clínico dos dados anatómicos acima referidos permitiu a implementação de técnicas de Radiologia de Intervenção no tratatamento de uma doença de elevada prevalência. ------------------------------- ABSTRACT: Benign prostatic hyperplasia (BPH) has high prevalence in men aged 50–79 years being ubiquitous with aging. Due to significant morbi-mortality associated with currently available medical and surgical treatments, there is the need for innovative technologies to continue to improve outcomes and minimize patient discomfort and morbidity. Recently, prostatic arterial embolization (PAE) was suggested as a treatmentoption for BPH based on preliminary results from animal studies and 3 treated patients. We decided to investigate if PAE might be a successful treatment option for severely symptomatic BPH patients. We performed a clinical and anatomical-radiological study in 63 patients with the use of an inovative image-guided minimally invasive technique. We evaluated 126 pelvic sides using Angio-MR or Angio-CT and Catheter Angiography before embolisation to treat symptomatic BPH. We aimed to define the main branching patterns of the male internal iliac arteries, so far only studied in the cadaver. We also evaluated the prostatic arterial supply, identifying: 1 the prostatic arteries; 2 origin and direction; 3 intra-prostatic branches; 4 anastomoses with surrounding arteries. Regarding the anatomical study we identified 181 prostatic arteries, because in 43.7% of pelvic sides 2 separate prostatic vascular pedicles were found. The most frequent origin was the internal pudendal artery (39.7%) with the common glutealpudendal trunk (21%) and superior vesical arteries (18.2%) the next commonest. Less frequent origins were the obturator artery (12.1%), the inferior (3.9%) or superior (1.7%) gluteal arteries, rectal branches from the inferior mesenteric artery (1.7%) and the accessory pudendal artery (1.7%). There were anastomoses with the surrounding arteries in 57.9% of cases: termination of the internal pudendal artery (41.6%), contralateral prostatic arteries (18.2%), same-side prostatic arteries (11.7%), rectal branches (15.6%), and vesical arteries (12.9%).Regarding the clinical study, we treated 63 patients aged 52–82 years (mean 69.5 years) who presented with symptomatic BPH refractory to medical treatment for at least 6 months. Follow-up evaluation (mean 4.7 months, range 1-12 months) was possible in 37 patients. PAE was achieved in all patients with bilateral embolization in 73%. In 27% PAE was performed unilaterally due to tortuosity, atherosclerotic changes and small size of iliac and prostatic arteries. There was a mean decrease in the IPSS of 10.8 points, a mean improvement in QoL of 1.5 points, and a mean increase in the sexual function score of 2.1 points. There was a mean PSA reduction of 30% (2.4 ng/mL), a Qmax increase of 3.1 to 3.85 mL/sec, and a mean prostate volume decrease of 21% (18.5 mL). There was one major complication: a small area of bladder wall ischemia treated by surgery. Overall, 75% of patients were considered clinical success with major improvement after PAE, while 25% of patients were considered clinical failure with little or no improvement after PAE. All remaining patients are under follow-up, stopped all prostatic medication, and reported no sexual dysfunction. This study is the first one to describe the radiological anatomy of the prostatic arteries, with the use of imaging techniques never used for this purpose before. The clinical use of the anatomical findings allowed the implementation of Interventional Radiology tehniques in the treatment of a disease with a high prevalence.

Privatization and social welfare in an international mixed Stackelberg duopoly

Competition between public and private firms exists in a range of industries like telecommunications, electricity, natural gas, airlines industries, as weel as services including hospitals, banking and education. Some authors studied mixed oligopolies under Cournot competition (firms move simultaneously) and some others considered Stackelberg models (firms move sequentially). Tomaru [1] analyzed, in a Cournot model, how decision-making upon cost-reducing R&D investment by a domestic public firm is affected by privatization when competing in the domestic market with a foreign firm. He shows that privatization of the domestic public firm lowers productive efficiency and deteriorates domestic social welfare. In this paper, we examine the same question but in a Stackelberg formulation instead of Cournot. The model is a three-stage game. In the first stage, the domestic firm chooses the amount of cost-reducing R&D investment. Then, the firms compete à la Stackelberg. Two cases are considered: (i) The domestic firm is the leader; (ii) The foreign firm is the leader. We show that the results obtained in [1] for Cournot competition are robust in the sence that they are also true when firms move sequentially.

Welfare effects of entry into international markets with licensing

We study the effects of entry of a foreign firm on domestic welfare in the presence of licensing, when the entrant is technologically inferior to the incumbent. We show that foreign entry increases domestic welfare for intermediate (respectively, sufficiently large) technological differences between the firms under licensing with fixed fee (respectively, output royalty).
