This article considers some implications of the new health consciousness and movements--holistic health and self-care--for the definition of and solution to problems related to "health." Healthism represents a particular way of viewing the health problem, and is characteristic of the new health consciousness and movements. It can best be understood as a form of medicalization, meaning that it still retains key medical notions. Like medicine, healthism situates the problem of health and disease at the level of the individual. Solutions are formulated at that level as well. To the extent that healthism shapes popular beliefs, we will continue to have a non-political, and therefore, ultimately ineffective conception and strategy of health promotion. Further, by elevating health to a super value, a metaphor for all that is good in life, healthism reinforces the privatization of the struggle for generalized well-being.

Resumo A pandemia e a inerente alteração de comportamentos, a par da parca previsibilidade, geraram maior ansiedade na população. Nesse sentido, este trabalho teve como objetivo analisar se os níveis de depressão, ansiedade e estresse em estudantes universitários se alteraram no período pandêmico (2020) comparativamente a períodos anteriores/normais. O estudo foi constituído por dois grupos, sendo a amostra 1 constituída por 460 sujeitos com idade média de 20,14 anos, e a amostra 2 por 159 sujeitos com idade média de 20,40 anos. Todos preencheram um questionário sociodemográfico e as escalas de ansiedade, depressão e estresse. Os estudantes que integraram o estudo no período pandêmico apresentaram níveis significativamente mais elevados de depressão, ansiedade e estresse comparativamente aos que integraram o estudo no período normal. Os resultados sugerem um impacto psicológico negativo da pandemia nos estudantes. Importa continuar a explorar as implicações da pandemia na saúde mental dos estudantes, para que se possam prevenir e minorar os seus efeitos.

Over the last decade, the number of studies reporting the use of electrospray ionization mass spectrometry (ESI-MS) in combination with collision cells (or other activation methods) to promote fragmentation of synthetic and natural products for structural elucidation purposes has considerably increased. However, the lack of a systematic compilation of the gas-phase fragmentation reactions subjected to ESI-MS/MS conditions still represents a challenge and has led to many misunderstood results in the literature. This review article exploits the most common fragmentation reactions for ions generated by ESI in positive and negative modes using collision cells in an effort to stimulate the use of this technique by non-specialists, undergraduate students and researchers in related areas.

Xylella fastidiosa is a xylem-dwelling, insect-transmitted, gamma-proteobacterium that causes diseases in many plants, including grapevine, citrus, periwinkle, almond, oleander, and coffee. X. fastidiosa has an unusually broad host range, has an extensive geographical distribution throughout the American continent, and induces diverse disease phenotypes. Previous molecular analyses indicated three distinct groups of X. fastidiosa isolates that were expected to be genetically divergent. Here we report the genome sequence of X. fastidiosa (Temecula strain), isolated from a naturally infected grapevine with Pierce's disease (PD) in a wine-grape-growing region of California. Comparative analyses with a previously sequenced X. fastidiosa strain responsible for citrus variegated chlorosis (CVC) revealed that 98% of the PD X. fastidiosa Temecula genes are shared with the CVC X. fastidiosa strain 9a5c genes. Furthermore, the average amino acid identity of the open reading frames in the strains is 95.7%. Genomic differences are limited to phage-associated chromosomal rearrangements and deletions that also account for the strain-specific genes present in each genome. Genomic islands, one in each genome, were identified, and their presence in other X. fastidiosa strains was analyzed. We conclude that these two organisms have identical metabolic functions and are likely to use a common set of genes in plant colonization and pathogenesis, permitting convergence of functional genomic strategies.

AI research is growing rapidly raising various ethical issues related to safety, risks, and other effects widely discussed in the literature. We believe that in order to adequately address those issues and engage in a productive normative discussion it is necessary to examine key concepts and categories. One such category is anthropomorphism. It is a well-known fact that AI's functionalities and innovations are often anthropomorphized (i.e., described and conceived as characterized by human traits). The general public's anthropomorphic attitudes and some of their ethical consequences (particularly in the context of social robots and their interaction with humans) have been widely discussed in the literature. However, how anthropomorphism permeates AI research itself (i.e., in the very language of computer scientists, designers, and programmers), and what the epistemological and ethical consequences of this might be have received less attention. In this paper we explore this issue. We first set the methodological/theoretical stage, making a distinction between a normative and a conceptual approach to the issues. Next, after a brief analysis of anthropomorphism and its manifestations in the public, we explore its presence within AI research with a particular focus on brain-inspired AI. Finally, on the basis of our analysis, we identify some potential epistemological and ethical consequences of the use of anthropomorphic language and discourse within the AI research community, thus reinforcing the need of complementing the practical with a conceptual analysis.

ABSTRACT: This paper focuses on an issue attracting increasing attention: the possible disadvantage inflicted on non‐Anglophone academics by the dominance of English in scientific publication and academic exchange. We critically review the evidence for linguistic disadvantage, noting some of its limitations, and critique the native/non‐native distinction as a coarse and somewhat unsatisfactory criterion for distinguishing between the advantaged and disadvantaged. In the second part of the paper we report on an empirical survey of the attitudes of Spanish academics at the University of Zaragoza to the possible disadvantage they may experience in publishing in English, and we investigate determinants of these attitudes. Though the survey shows, as expected, that a majority do feel disadvantaged in academic publication relative to Anglophone scholars, it also indicates, we argue, that attitudes are more complex and multidimensional than the literature sometimes suggests. Self‐reported language proficiency emerges as a significant determinant of attitudes. The final part of the paper discusses a number of proposed language planning interventions designed to redress linguistic disadvantage. We argue that some of the more radical of these are flawed or unfeasible and suggest that more modest measures have a greater likelihood of ameliorating the situation.

The plant hormones jasmonic acid and methyl jasmonate, along with their intermediate compounds, produced in the octadecanoid pathway, are important signaling molecules that are collectively called jasmonates. These are widespread in the plant kingdom and play crucial roles in biotic/abiotic stress responses, as well as in processes related to plant growth and development. Recently, it has been shown that jasmonates are also involved in reproductive processes. We present the most recent findings related to the biosynthesis, regulation and signaling mechanisms of jasmonates. Additionally, we discuss the identification of [(+)-7-iso-JA-L-Ile] as the active biological hormonal form of jasmonate; this fills the greatest gap in our knowledge about the signaling mechanism that is responsible for the activation of downstream genes in the jasmonate-signaling cascade. The identification of several Arabidopsis thaliana mutants was crucial to the elucidation of the signaling mechanisms involved in jasmonate-mediated responses. Finally, the involvement of jasmonates in the reproductive process of Nicotiana tabacum L. is briefly discussed, since some of the main enzymes of the jasmonic acid biosynthesis pathway were identified in a stigma/style expressed sequence tag database (TOBEST) of this Solanaceae species.

This chapter outlines a methodology for the interpretation of historical sources, helping to realize their full potential for the study of organization, while overcoming their challenges in terms of distortions created by time, changes in context, and selective production or preservation. Drawing on social scientific methods as well as the practice and reflections of historians, the chapter describes analytical and interpretive process based on three basic elements, illustrating them with exemplars from management research: source criticism to identify possible biases and judge the extent to which a source can be trusted to address the research question; triangulation with additional sources to confirm or question an interpretation and strengthen the overall findings; hermeneutics to relate sources to their original contexts and make their interpretation by a researcher today more robust. The chapter contributes to the creation of a language for describing the use of historical sources in management research.

El paradigma cualitativo de investigación se presenta en la salud como una orientación que profundiza en la subjetividad de los individuos, con quienes interactúa para obtener mayor conocimiento de estos y de los fenómenos y conductas que los atañen.La entrevista se enmarca dentro del quehacer cualitativo como una herramienta eficaz para desentrañar significaciones, las cuales fueron elaboradas por los sujetos mediante sus discursos, relatos y experiencias. De esta manera se aborda al sujeto en su individualidad e intimidad. Por esto, el texto tiene como objetivo establecer una guía práctica y necesaria para la consecución correcta de entrevistas en el área de la investigación cualitativa en salud. Así, también presentan los pasos y técnicas necesarias para lograrlo.

A previous paper of mine, that criticized Suppes' probabilistic theory of causality, was in turn criticized by Deborah Rosen. This paper is a development of my argument and an answer to Rosen. It is argued that the concept of causation is used in contemporary science in a way that presupposes determinism. It is shown that deterministic assumptions are necessary for inferences from generic to individual causal relations and for various kinds of eliminative arguments.

This paper examines the spatial pattern of ill-defined causes of death across Brazilian regions, and its relationship with the evolution of completeness of the deaths registry and changes in the mortality age profile. We make use of the Brazilian Health Informatics Department mortality database and population censuses from 1980 to 2010. We applied demographic methods to evaluate the quality of mortality data for 137 small areas and correct for under-registration of death counts when necessary. The second part of the analysis uses linear regression models to investigate the relationship between, on the one hand, changes in death counts coverage and age profile of mortality, and on the other, changes in the reporting of ill-defined causes of death. The completeness of death counts coverage increases from about 80% in 1980-1991 to over 95% in 2000-2010 at the same time the percentage of ill-defined causes of deaths reduced about 53% in the country. The analysis suggests that the government's efforts to improve data quality are proving successful, and they will allow for a better understanding of the dynamics of health and the mortality transition.

In 1985 Alchourrón, Gärdenfors and Makinson presented their now classic theory (ACM) of theory change (belief revision). In 1988 Adam Grove, generalizing David Lewis's theory of counterfactuals, presented a model theory suitable for the AGM theory. Although AGM and Grove mentioned object languages, neither used them. But recently, Maarten de Rijke has shown how object languages can be brought into the picture. In the present paper we take de Rijke's idea further, addressing the question whether there is a particular doxastic or epistemic logic implicit in AGM.

Desulfovibrio gigas hydrogenase (EC 1.12.2.1) is a complex enzyme containing one nickel, one 3Fe, and two [Fe4S4] clusters (Teixeira, M., Moura, I., Xavier, A. V., Der Vartanian, D. V., LeGall, J., Peck, H. D., Jr., Huynh, B. H., and Moura, J. J. G. (1983) Eur. J. Biochem. 130, 481-484). This hydrogenase belongs to a class of enzymes that are inactive "as isolated" (the so-called "oxygen-stable hydrogenases") and must go through an activation process in order to express full activity. The state of characterization of the active centers of the enzyme as isolated prompted us to do a detailed analysis of the redox patterns, activation profile, and catalytic redox cycle of the enzyme in the presence of either the natural substrate (H2) or chemical reductants. The effect of natural cofactors, as cytochrome C3, was also studied. Special focus was given to the intermediate redox species generated during the catalytic cycle of the enzyme and to the midpoint redox potentials associated. The available information is discussed in terms of a "working hypothesis" for the mechanism of the [NiFe] hydrogenases from sulfate reducing organisms in the context of activation process and catalytic cycle.

The present study used a temporal bisection task with short (<2 s) and long (>2 s) stimulus durations to investigate the effect on time estimation of several musical parameters associated with emotional changes in affective valence and arousal. In order to manipulate the positive and negative valence of music, Experiments 1 and 2 contrasted the effect of musical structure with pieces played normally and backwards, which were judged to be pleasant and unpleasant, respectively. This effect of valence was combined with a subjective arousal effect by changing the tempo of the musical pieces (fast vs. slow) (Experiment 1) or their instrumentation (orchestral vs. piano pieces). The musical pieces were indeed judged more arousing with a fast than with a slow tempo and with an orchestral than with a piano timbre. In Experiment 3, affective valence was also tested by contrasting the effect of tonal (pleasant) vs. atonal (unpleasant) versions of the same musical pieces. The results showed that the effect of tempo in music, associated with a subjective arousal effect, was the major factor that produced time distortions with time being judged longer for fast than for slow tempi. When the tempo was held constant, no significant effect of timbre on the time judgment was found although the orchestral music was judged to be more arousing than the piano music. Nevertheless, emotional valence did modulate the tempo effect on time perception, the pleasant music being judged shorter than the unpleasant music.

O presente artigo procura analisar a reforma trabalhista sancionada recentemente no Brasil. Para isso, são destacados os seus efeitos sobre a configuração dos elementos centrais da relação de emprego (formas de contratação, jornada, remuneração e proteção social) e sobre a organização sindical. Parte-se da hipótese que a reforma trabalhista em questão ajusta a regulação do trabalho às características do capitalismo contemporâneo, predominando a visão do trabalho como “labor” e não como “opus”. A reforma amplia a liberdade dos empregadores em determinar as condições de contratação, o uso da força de trabalho e a remuneração dos trabalhadores. Ou seja, busca-se imputar o processo de definição das regras da relação de emprego às empresas, restringindo a participação das organizações dos trabalhadores e do Estado. Esse processo acarreta, primeiramente, o aumento da insegurança dos trabalhadores e a perda de direitos, bem como a diminuição da proteção social. A reforma também busca esvaziar as organizações sindicais na qualidade de organizações de classe, visto que passa a prevalecer a visão de organizações mais descentralizadas e articuladas com os interesses das empresas.

This report discuss Problem-Based and Project-Based Learning (PBL) as an approach to meeting the demand for the educational requirements of the next generation engineering graduates. The report is prepared as the final report of the Special Interest Group (SIG) B5 of the Erasmus Thematic Network Project TREE (Teaching and Research in Engineering Education) on ProblemBased and Project-Based Learning. In engineering education there is a shift in emphasis from professional skills to process skills. These skills include problem analysis and problem solving, project management and leadership, analytical skills and critical thinking, dissemination and communication, interdisciplinary competencies, intercultural communication, innovation and creativity, and social abilities. PBL is an instructional method that challenges students to learn to learn, working cooperatively in groups to seek solutions to real world problems. These problems are used to engage students' curiosity and initiate learning the subject matter. PBL prepares students to think critically and analytically, and to find and use appropriate learning resources. PBL is both a curriculum and a process. The curriculum consists of carefully selected and designed problems that demand from the learner acquisition of critical knowledge, problem solving proficiency, self-directed learning strategies, and team participation skills. The process replicates the commonly used systemic approach to resolving problems or meeting challenges that are encountered in life and career. This report gives a survey of PBL and several best practice examples from Europe, and discusses how an institution can change to PBL. The conclusion of this report is that PBL can, regardless of discipline, enhance students' achievement of both professional skills and process skills. Therefore European higher education institutions should consider shifting to PBL. The shift to PBL cannot be accomplished as a sudden change. It should be considered as a strategic change and the necessary measures should be taken for successful completion of change.
