Vivências anímicas e percepção subjetiva de qualidade de vida: perspectiva de servidores públicos nos âmbitos da saúde e da educação

This study was qualitative in nature and aimed to investigate the possible interference of spiritual experiences with the subjective perception of quality of life. The perspectives of civil servants in education and health services were compared. The study was developed through bibliographic and exploratory research, and the instrument used for data collection for the exploratory research was the WHOQOL-bref, which was applied in two stages: before and after experiences with spiritual activities. The purposive sample used in this study was composed of civil servants working in health and education administrative sectors of the Brazilian Unified Health System and a State University, respectively, with the intention of broadening the understanding about the perception of quality of life in civil servants from different sectors. The exploratory research of the study was carried out in three stages. The first was a two-phase data collection, before and after experiences with spiritual activities offered to civil servants who worked in the health care field, as well as the analysis of the results of this step. The second stage was the collection of data before and after experiences with spiritual activities offered to civil servants who worked in the administrative sector of education in a public university, besides the analysis of the results of this step. The third stage consisted of a comparison of the results obtained in the preceding two steps. The data resulting from the use of the research instrument for both samples were analyzed via Thematic Content Analysis. A questionnaire containing 26 questions based on four main themes was used. The first two questions were related to perceived quality of life and health satisfaction and they were not part of the specific domains. The other 24 questions were divided between the four themes: physical domain, psychological domain, domain of social relations, and environmental domain. The results...

Interview W.T. "Dub" Massey

In his April 27th, 1981 interview with Phil O’Quinn, W.T. Massey recollects his involvement in the Civil Rights Movement as one of the Friendship 9 protestors and non-violent activists. Massey retells the preparation and events leading up to the sit-in at McCrory’s lunch counter. Massey also shares the negative effects he experienced with his involvement as an activist and leader in the Civil Rights Movement, in particular, his arrest from the McCrory’s sit-in. Massey concludes his interview with advice and hope for the black community. This interview was conducted for inclusion into the Louise Pettus Archives and Special Collections Oral History Program.

ESSAYS ON INTERNATIONAL RESEARCH AND DEVELOPMENT SPILLOVERS

The dissertation consists of three essays on international research and development spillovers. In the first essay, I investigate the degree to which differences in institutional arrangements among Sub-Saharan African countries determine the extent of benefits they derive from foreign research and development spillovers. In particular, I compare the international research and development spillovers for English common law and French civil law Sub-Saharan African countries. I show that differences in the legal origin of the company law or commercial codes in these countries may reflect the extent of barriers they place in the paths of firms that engage in the investment process. To tests this hypothesis, I constructed foreign R&D spillovers variable using imports as weights and employed the endogenous growth framework to estimate elasticities of productivity with respect to foreign R&D spillovers for a sample of 17 English common law and French Civil law Sub-Saharan African countries over the period 1980-2004. My results find support for the hypothesis. In particular, foreign R&D spillovers were higher in the English common law countries than in the French civil law countries. In the second essay, I examine the question of whether technical cooperation grants and overseas development assistance grants induce R&D knowledge spillovers in Sub-Saharan African countries. I test this hypothesis using data for 11 Sub-Saharan African countries over the period 1980-2004. I constructed foreign R&D spillovers using the technical cooperation grants and overseas development assistance grants as weights and employed the endogenous growth framework to provide quantitative estimates of foreign R&D spillover effects in 11 Sub-Saharan African countries. I find that technical cooperation grants and overseas development assistance grants are major mechanisms through which returns to R&D investments in G7 countries flows to Sub-Saharan African countries. However, their influence has declined over the years. Finally, the third essay tests the hypothesis that the relationship between a country's exporters and their foreign purchasing agents may lead to the exchange of ideas and thereby improve the manufacturing process and productivity in the exporting country. I test this hypothesis using disaggregated export data from OECD countries. The foreign R&D capital stock in this essay was constructed as exports weighted average of domestic R&D capital stock. I find empirical support for the hypothesis. In particular, capital goods exports generate more learning effects and therefore best explain productivity in OECD countries than non-capital goods exports.

Questões controvertidas sobre a responsabilidade do sócio e do ex-sócio no processo do trabalho

O presente estudo objetiva traçar um panorama atual sobre a responsabilidade subsidiária dos sócios nas hipóteses em que, em fase de execução no processo do trabalho, os bens da pessoa jurídica sejam insuficientes para satisfação dos créditos. A matéria propriamente dita nada tem de nova, remontando aos primeiros decretos que regulamentavam as sociedades por quotas de responsabilidade limitada, passando pelo Código Civil de 1916 e de 2002. Todavia, o estudo procurará demonstrar que, aos poucos, foi sendo abandonada a exigência de comprovação dos amplos poderes de mando e gestão do sócio, ou seu exercício abusivo, assim como foi aumentando simultaneamente a preocupação com a figura dos ex-sócios, objeto de investigação especial no presente trabalho. O artigo sustentará a tese de que essa maior liberdade na interpretação da responsabilidade de sócios e ex-sócios se deve, sobretudo, (a) à promiscuidade patrimonial verificada entre pessoas jurídicas e pessoas naturais, na sociedade brasileira, (b) às altíssimas taxas de encerramento das pessoas jurídicas logo no primeiro ou no segundo ano de existência e (c) à elevada rotatividade de sócios nos estatutos da empresa.

Aspetti processuali del Regolamento n. 1/2003/Ce

The recent reform in European antitrust enforcement is embodied in Regolation n. 1/2003/ Ce and related Communications. Since 2004 when it came into force, some crytical assessments can already be made. The work starts from some technical analysis of the reform, under a procedural perspective, to assess the proceedings’ real impact on parties’ rights and to criticize its limits. Decentralisation has brought about more complicacies, since community procedural systems are not harmonized, neither in their administrative rules, nor in their civil proceedings, which are all involved in the European antitrust network. Therefore, antitrust proceedings end un as being more jurisdictional in their effects than in their guarentees, which is a flaw to be mended by legislators. National laws shoud be harmonized, community law should be clarified and the system should turn more honestly towards a rationalized jurisdiction-cented mechanism. Otherwise, parties defense rights and the overall efficiency are put into doubt. Italy is a good exemple of how many colmlicacies can outburst from national procedures and national decentralised application. An uncertain pattern of judicial control, together with unclear relationships among the institutions to cooperate in the antitrust network can produce more problems than they aim to solve. As to the private enforcement, Regulation n.1 does not even attempt to give precise regulation to this underdeveloped sector. A continual comparison with U.S. system has brought the Commission to become aware both of the risks and of the advanteges of an increased civil antitrust litigation in fronto of national judges. In order to substain a larger development of this parallel and, presently, difficult way of judicial compensation, it is presently ongoing a consultation among states to find suitable incentives to make private enforcement more appealing and effective. The solution to this lack of private litigation is not to be sought in Regulation n. 1 which calls into action national legislators and proceedures to implement further improvements. As a conclusion, Regulation n. 1 is the outpost of an ambitious community design to create an efficient control mechanism over antitrust violations. It focuses on Commission proceedings, powers and sanctions in order to establish deterrence, then it highlights civil litigation perspectives and it involves directly states into antitrust application. It seems that more could be done to technically shape administrative proceedings in a more jurisdictionally oriented form, then to clarify respective roles and coordination mecanisms in order to prevent difficulties easy to forsee. Some of jurisprudential suggestions have been accepted, but much more is left to be done in the future to improve european antitrust enforcement system.

The binding mode of side chain- and C3-modified epothilones to tubulin

The tubulin-binding mode of C3- and C15-modified analogues of epothilone A (Epo A) was determined by NMR spectroscopy and computational methods and compared with the existing structural models of tubulin-bound natural Epo A. Only minor differences were observed in the conformation of the macrocycle between Epo A and the C3-modified analogues investigated. In particular, 3-deoxy- (compound 2) and 3-deoxy-2,3-didehydro-Epo A (3) were found to adopt similar conformations in the tubulin-binding cleft as Epo A, thus indicating that the 3-OH group is not essential for epothilones to assume their bioactive conformation. None of the available models of the tubulin-epothilone complex is able to fully recapitulate the differences in tubulin-polymerizing activity and microtubule-binding affinity between C20-modified epothilones 6 (C20-propyl), 7 (C20-butyl), and 8 (C20-hydroxypropyl). Based on the results of transferred NOE experiments in the presence of tubulin, the isomeric C15 quinoline-based Epo B analogues 4 and 5 show very similar orientations of the side chain, irrespective of the position of the nitrogen atom in the quinoline ring. The quinoline side chain stacks on the imidazole moiety of beta-His227 with equal efficiency in both cases, thus suggesting that the aromatic side chain moiety in epothilones contributes to tubulin binding through strong van der Waals interactions with the protein rather than hydrogen bonding involving the heteroaromatic nitrogen atom. These conclusions are in line with existing tubulin polymerization and microtubule-binding data for 4, 5, and Epo B.

Democratic Transition and Political Patronage

Mr. Korosenyi begins by analysing the particular relationship holding between politics and administration in different countries. Within Europe three major patterns have emerged in the 20th century. Firstly there is the politically neutral British Civil Service, secondly the German and French state bureaucracies, which traditionally are supposed to embody the "common good", and thirdly there is the patronage system of the so-called consociate democracies, e.g. Austria. In general Mr. Korosenyi believes that, though politics do not penetrate into the Hungarian administration to the extent they do in Belgium and Austria, nevertheless, there is a stronger fusion than there is in the traditional British pattern. He is particularly interested in this relationship with regard to its effect on democratic institution building and the stabilisation of the new regime in Hungary, now the old "nomenklatura" system has been abolished. The structure of the Hungarian government was a result of the constitutional amendments of 1989 and 1990. Analysing this period, it becomes clear that for all the political actors who initiated and supported the democratic transition to democracy, the underlying assumption was a radical depoliticisation of the administration in order to maintain its stability. The political leadership of the executive is a cabinet government. The government is structured along ministries, each headed by a politician, i.e. the minister, who is a member of the cabinet. The minister's political secretary is not a cabinet member, but he or she is a politician, usually a member of the parliament. The head of the administration of the ministry is the administrative state secretary, who is a civil servant. He or she usually has four deputies, also civil servants. Naturally it is assumed that there should be a clear separation between politicians and civil servants. However in practice, the borders can be blurred, giving rise to a hybrid known as the "political civil servant". Mr. Korosenyi analyses the different faces of these hybrids. They are civil servants for the following reasons. They need special educational qualifications, working experience, a civil service exam etc., they are not allowed to do anything which is incompatible with their impartial role, and they cannot occupy political office nor may they appear in the name of any political party. On the other hand, the accepted political dimension to their function is revealed by the following facts. The state secretary (a civil servant) may participate in cabinet meetings instead of the minister. The state secretary is employed by the minister. A state secretary or any of their deputies can be dismissed at any time by the minister or the prime minister. In practice then, ministers appoint to these senior administrative positions civil servants whose personal and political loyaties are strong. To the second level of political patronage in ministries belong the ministerial cabinet, press office and public relation office. The ministerial cabinet includes the private advisors and members of the personal staff of the minister. The press office and the PR office, if they exist, are not adjusted to the administrative hierarchy of the ministry, but under the direct control of the minister. In the beginning of the 1990s, such offices were exceptions; in the second half of the 90s they are accepted and to be found in most ministries. Mr. Korosenyi's work, a 92-page manuscript of a book in Hungarian, marks the first piece of literature within the field of political science which analyses the structure of the Hungarian government in the 1990s and the relationship between the political leadership and the public administration.

Silhouettella loricatula (Arachnida, Araneae, Oonopidae): a Haplogyne spider with complex female genitalia

The female genital system of the oonopid Silhouettella loricatula is astonishingly complex. The genital opening is situated medially and leads into an oval receptaculum that is heavily sclerotized except for the ventral half of the posterior wall that appears chitinized only. A large striking sclerite lying in the posterior wall of the uterus externus is attached anteriorly to the receptaculum and continues dorsally into a globular appendix that bears a furrow. The uterus externus shows a peculiar modification in its anterior wall: a paddle-like sclerite with a nail-like posterior process. This sclerite lies opposite to the furrow proceeding in the globular appendix and may serve females to lock the uterus externus by muscle contractions. Massive muscles connect the sclerite with the anterior scutum of the opisthosoma and with two other sclerites that are attached to the receptaculum and serve as attachments for further muscles. Gland cells extend around a pore field of the receptaculum. They produce secretion that encloses spermatozoa in a discrete package (secretory sac) inside the receptaculum. In this way, the mixing of sperm from different males and thus sperm competition may be severely limited or completely prevented. During a copulation in the laboratory the ejection of a secretory sac that most probably contained spermatozoa was observed, indicating sperm dumping in S. loricatula. The ejection of the secretory sac may be caused by female muscle contractions or by male pedipalp movements. The majority of the investigated females have microorganisms in the receptacula that could represent symbionts or infectious agents. The microorganisms can be identified partly as bacteria. They are enclosed in secretion and are always found in the same position inside the receptaculum.

Distally based abductor hallucis muscle flap: anatomic basis and clinical application

Although rarely used, the abductor hallucis muscle has its indications in coverage of small defects at the medial aspect of the hindfoot as a proximally based muscle flap. The authors describe a 69-year-old female patient in whom the abductor hallucis muscle was used as a distally based flap to reconstruct a defect in the forefoot. An anatomic study was undertaken on two cadaveric feet to explore the practicality of the distally based abductor hallucis muscle flap before it was applied clinically. The distally based abductor muscle flap receives its blood supply from minor and major pedicles in a retrograde fashion from both the dorsal arterial network and the deep plantar system, through communicating branches with the medial plantar artery distally. Transposition of the distally based hallucis flap is only advisable in individuals who have no vascular compromise in the lower leg and foot. To the authors' knowledge, this modification has not yet been described in the available literature.
