Proactive management of extreme prematurity: disagreement between obstetricians and neonatologists

Objective: To verify, in extremely preterm infants, if disagreement between obstetricians and neonatologists regarding proactive management is associated with early death. Study Design: Prospective cohort of 484 infants with 23(0/7) to 26(6/7) weeks, without malformations, born from January 2006 to December 2009 in eight Brazilian hospitals. Pro-active management was defined as indication of >= 1 dose of antenatal steroid or cesarean section (obstetrician) and resuscitation at birth according to the international guidelines (neonatologist). Main outcome was neonatal death in the first 24 h of life. Result: Obstetricians and neonatologists disagreed in 115 (24%) patients: only neonatologists were proactive in 107 of them. Disagreement between professionals increased 2.39 times the chance of death in the first day (95% confidence interval 1.40 to 4.09), adjusted for center and maternal/neonatal clinical conditions. Conclusion: In infants with 23 to 26 weeks of gestation, disagreement between obstetricians and neonatologists, translated as lack of antenatal steroids and/or vaginal delivery, despite resuscitation procedures, increases the odds of death in the first day.

A new species of Almeidea (Galipeinae, Galipeeae, Rutaceae) from Eastern Brazil

A new species of Almeidea (Rutaceae) belonging to the neotropical tribe Galipeeae (subtribe Galipeinae) is described and illustrated. This new species, Almeidea albiflora, is known so far only from a few collections made in small disturbed forest remnants in the vicinity of Cachoeiro de Itapemirim, in the state of Espirito Santo, and by a single collection from northern Rio de Janeiro state, both in the domain of the Atlantic Forest, Eastern Brazil. Diagnostic features, like white petals, sericeous ovary and distal secondary axes as long as the proximal ones are identified. Pollen morphology is also described, and brief discussions of the relationships of the new taxon to other species of Almeidea, as well as comments on its conservation status, are provided.

The ethics of germ line gene manipulation - A five dimensional debate

Contributors to the debate surrounding the ethics of germ line gene manipulation have by and large concentrated their efforts on discussions of the potential risks that are associated with the use of this technology. Many international advisory committees have ruled out the acceptability of germ line gene manipulation at least for the time being. The purpose of this work is to generate much needed discussion on the many other ethical issues concerning the implementation of not only germ line gene manipulation but also other related biotechnologies. In this paper I systematically investigate and analyse the most salient issues put forward by proponents and opponents alike. I argue that if germ line manipulation proves to be a safe and effective procedure, then the principle of beneficence imposes on the medical profession a moral duty to pursue the technology.

The morals of metaphysics: Kant's 'Groundwork' as intellectual paideia

To approach philosophy as a way of working on the self means to begin not with the experience it clarifies and the subject it discovers, but with the acts of self‐transformation it requires and the subjectivity it seeks to fashion. Commenting on the variety of spiritual exercises to be found in the ancient schools, Pierre Hadot remarks that: Some, like Plutarch’s ethismoi, designed to curb curiosity, anger or gossip, were only practices intended to ensure good moral habits. Others, particularly the meditations of the Platonic tradition, demanded a high degree of mental concentration. Some, like the contemplation of nature as practiced in all philosophical schools, turned the soul toward the cosmos, while still others—rare and exceptional—led to a transfiguration of the personality, as in the experiences of Plotinus. We also saw that the emotional tone and notional content of these exercises varied widely from one philosophical school to another: from the mobilization of energy and consent to destiny of the Stoics, to the relaxation and detachment of the Epicureans, to the mental concentration and renunciation of the sensible world among the Platonists.1 While successfully applied to ancient philosophy,2 this approach has not been widely exploited in the history of philosophy more broadly. There is, however, at least one study of medieval metaphysics in these terms,3 and there are some important discussions of early modern Stoicism and Epicureanism.4 And a recent study of Hume shows the fruitfulness of the approach for Enlightenment philosophy.5 It is all the more surprising then that there seems to have been no serious attempt to approach Kant’s moral philosophy in this way.

G-values for scission and crosslinking on γ-radiolysis of Ultem at 303 K

The radiation chemical yields G(S) and G(X) for H-linking and Y-linking models for Ultem have been calculated from molecular weight analysis by gel permeation chromatography. These G-values have been compared with the G-values obtained from analysis of soluble fractions above the gel dose, Which have been reported in previous works. An analysis of the molecular weight data in terms of H-linking and Y-linking mechanisms yielded values of G(S-H) = 1.0 x 10(-3) and G(H) = 6.0 x 10(-3) and G(S-Y) = 1.3 x 10(-2) and G(Y) = 1.8 x 10(-2). The corresponding values obtained from the solubility data were G(SH) = 0.53 x 10(-2), G(H) = 1.39 x 10(-2), G(S-Y) = 4.2 x 10(-2) and G(Y) - 4.6 x 10(-2). The origin of the disagreement between the molecular weight and solubility values is not clear, but it could arise as a result of observed microgel formation below the reported gel dose of 0.13 MGy. Whether the crosslink mechanism proceeds by an H-linking or Y-linking process is also unclear and will require direct observation of the crosslinking structures.

South-South relations and the English School of International Relations: Chinese and Brazilian ideas and involvement in Sub-Saharan Africa

The rise of large developing countries has led to considerable discussions of re-balancing global relations and giving greater priority to understanding South-South relations. This paper, in exploring the central ideas of Chinese and Brazilian foreign policy and the behavior of these two rising Southern countries toward Sub-Saharan Africa, argues that the English School of International Relations is well suited to understanding the intentions and actions that characterize South-South relations.

AN ELISA SUITABLE FOR THE DETECTION OF RABIES VIRUS ANTIBODIES IN SERUM SAMPLES FROM HUMAN VACCINATED WITH EITHER CELL-CULTURE VACCINE OR SUCKLING-MOUSE-BRAIN VACCINE

An indirect ELISA for determination of post-vaccination rabies antibody was applied. Purified rabies virus was used as antigen to coat plates, and staphylococcal protein A linked with horseradish peroxidase was used for detecting IgG antibody in human sera. Sera from humans, vaccinated with cell-culture vaccine or suckling-mouse-brain vaccine, were examined. ELISA results were compared to those obtained from the virus neutralization test. The mean and standard deviation of OD were determined for 126 negative sera (pre-vaccination) and for 73 sera from vaccinated persons showing antibody titers lower than 0.5 IU/ml. Results were defined as ELISA -positive, -negative or -doubtful. Establishment of a doubtful region reduced the number of sera otherwise classified as positive (false-positive sera). In this way, the sensitivity, specificity and agreement values were respectively 87.5%, 92.4% and 88.5%. No significant differences were observed in these values when the group vaccinated with cell-culture vaccine and the group vaccinated with suckling-mouse-brain vaccine were compared. It was shown that much of the disagreement between the values obtained by neutralization test and ELISA occurred in sera obtained at the beginning of the immunization process, and was probably due to the presence of IgM in the serum samples, detected only by the former test. This ELISA method can be used as a screening test in rabies laboratories regardless of the kind of vaccine used for immunization.

Discussing Chevalier’s data on the efficiency of tariffs for american and french canals in the 1830s

This article revisits Michel Chevalier’s work and discussions of tariffs. Chevalier shifted from Saint-Simonism to economic liberalism during his life in the 19th century. His influence was soon perceived in the political world and economic debates, mainly because of his discussion of tariffs as instruments of efficient transport policies. This work discusses Chevalier’s thoughts on tariffs by revisiting his masterpiece, Le Cours d’Économie Politique. Data Envelopment Analysis (DEA) was conducted to test Chevalier’s hypothesis on the inefficiency of French tariffs. This work showed that Chevalier’s claims on French tariffs are not validated by DEA.

The Future of the Deuteronomistic History

The present debate on the so-called "Deuteronomistic History" has become quite confusing and in recent years more and more scholars are inclined to deny the existence of a Deuteronomistic History as elaborated by Martin Noth or at least to modify this thesis radically. The contributions in this volume reflect the present state of discussion about the Deuteronomistic History. With one exception they have all been presented and discussed in three special sessions dedicated to "Deuteronomism" during the SBL International Meeting in Lausanne (July 1997). Three topics were treated: "The Future of the Deuteronomistic History", "Identity and Literary Strategies of the Deuteronomists", "Deuteronomism and the Hebrew Bible". The contributors are: R. Albertz, A.G. Auld, M. Bauks, W. Dietrich, D. Edelman, F. Garcia Lopez, E.A. Knauf, G. Knoppers, S.K. McKenzie, C. Nihan, T.C. Römer, N.H. Rösel, J. Van Seters and J. Vermeylen. Each contribution offers a valuable entry into one of the most important discussions of Old Testament scholarship at the end of the twentieth century.

On the use of QoS requirements as base of multicast charging

We propose a charging scheme for cost distribution along a multicast tree when cost is the responsibility of the receivers. This scheme focuses on QoS considerations and it does not depend on any specific type of service. The scheme has been designed to be used as a bridge between unicast and multicast services, solving the problem of charging multicast services by means of unicast charging and existing QoS routing mechanisms. We also include a numerical comparison and discussions of the case of non-numerical or relative QoS and on the application to some service examples in order to give a better understanding of the proposal

Careers of Managers, Comparison between ICT and Paper Business Sectors

The purpose of this study is to increase understanding of how the managers build their early career in information and communication technology industry (ICT business sector) and pulp- and paper industry (paper business sector). The focus of the study is to explore the importance differing a business sectors have in influencing managerial careers. Business sectors can affect careers in several ways.Sectors have different history and traditions. Also the age structure of ICT personnel differs from the age structure of personnel in the paper industry. Managers in the ICT and paper sector are technically educated but in different disciplines. Differences exist also in ways of recruiting and developing commitment inpersonnel. The target group of this research, middle management engineering personnel, work in Finnish ICT and paper companies. Research data were gathered in April-December 2002 in South-Karelia by interviewing 30 managers and six directors working in three Finnish ICT companies and in three paper companies. The research issue is approached on two levels: the individual level and the organizational level. The managers related their career stories in focused interviews. Directors, representing the organizations, described the generalities of the business sector and gave background information on company policies, human relationshippractices, as well as career and human resource development. Results of the study contribute to research discussions of career, life-span reasoning, socialization and commitment. Career is conceived as a series of positions including everykind of hierarchical mobility and all kinds of positions in work. A manager's career develops in interaction with the organization and it can be seen as involving a socializing process in an organization as a consequence of experiences andchanges in positions. This research contributes to the understanding of the nature of career in the context of two business sectors. Universal career theories,for the most part, do not perceive the importance of business sector in determining career experience. This study concentrates on describing and understanding early careers in two different business areas, elements committing managers to particular business sectors and the actions of companies in that particular sector. While career research began in the middle of 1950s, the theoretical basis of career research seems to be quite fragmented still. However, a dichotomy is consistently presented between traditional, hierarchical career research and boundaryless career thinking. In this research we examine how these old and new career concepts are evidence in the ICT and paper sectors. Careers are changing from formal, hierarchy-based structures to more fluid arrangements. The new boundaryless career concept captures territory from old career thinking. Mobility between employers, networks, and changing hierarchical structures in organizations, as well as personal and family reasons are theorized to bring changes to careers patterns in the future. However, the pace of this change in careers will vary between the ICT and paper business sectors. Findings of this research indicate that business sector has an effect on how managerial careers develop. The environment where career is developed differs between ICT and paper sectors. Careers begin differently in the two environments and the speed of career progression is distinct. ICT careers are built within the business sector whereas paper careers are made inside one company. Also recruiting and socialization practices differ from one sector to the other.

Evolution of the mating system in colonizing plants.

Colonization is likely to be more successful for species with an ability to self-fertilize and thus to establish new populations as single individuals. As a result, self-compatibility should be common among colonizing species. This idea, labelled 'Baker's law', has been influential in discussions of sexual-system and mating-system evolution. However, its generality has been questioned, because models of the evolution of dispersal and the mating system predict an association between high dispersal rates and outcrossing rather than selfing, and because of many apparent counter examples to the law. The contrasting predictions made by models invoking Baker's law versus those for the evolution of the mating system and dispersal urges a reassessment of how we should view both these traits. Here, I review the literature on the evolution of mating and dispersal in colonizing species, with a focus on conceptual issues. I argue for the importance of distinguishing between the selfing or outcrossing rate and a simple ability to self-fertilize, as well as for the need for a more nuanced consideration of dispersal. Colonizing species will be characterized by different phases in their life pattern: dispersal to new habitat, implying an ecological sieve on dispersal traits; establishment and a phase of growth following colonization, implying a sieve on reproductive traits; and a phase of demographic stasis at high density, during which new trait associations can evolve through local adaptation. This dynamic means that the sorting of mating-system and dispersal traits should change over time, making simple predictions difficult.

Social media and public libraries : exploring information activities of library professionals and users

Social media has become a part of many people’s everyday lives. In the library field the adoption of social media has been widespread and discussions of the development of “Library 2.0” began at an early stage. The aim with this thesis is to study the interface between public libraries, social media, and users, focusing on information activities. The main research question is: How is the interface between public libraries and social media perceived and acted upon by its main stakeholders (library professionals and users)? The background of Library 2.0 is strongly associated with the development of the Web and social media, as well as with the public libraries and their user-centered and information technological development. The theoretical framework builds on the research within the area of Library and Information Science concerning information behavior, information practice, and information activities. Earlier research on social media and public libraries is also highlighted in this thesis. The methods survey and content analysis were applied to map the interface between social media and public libraries. A questionnaire was handed out to the users and another questionnaire was sent out to the library professionals. The results were statistically analyzed. In the content analysis public library Facebook pages were studied. All the empirical investigations were conducted in the area of Finland Proper. An integrated analysis of the results deepens the understanding of the key elements of the social media and public library context. These elements are interactivity, information activities, perceptions, and stakeholders. In this context seven information activities were distinguished: reading, seeking, creating, communicating, informing, mediating, and contributing. This thesis contributes to develop the research concerning information activities and draws a realistic picture of the challenges and opportunities in the social media and public library context. It also contributes with knowledge on library professionals and library users, and the existing differences in their perceptions of the interface between libraries and social media.
