Mapping journalism cultures across nations : a comparative study of 18 countries

This article reports key findings from a comparative survey of the role perceptions, epistemological orientations and ethical views of 1800 journalists from 18 countries. The results show that detachment, non-involvement, providing political information and monitoring the government are considered essential journalistic functions around the globe. Impartiality, the reliability and factualness of information, as well as adherence to universal ethical principles are also valued worldwide, though their perceived importance varies across countries. Various aspects of interventionism, objectivism and the importance of separating facts from opinion, on the other hand, seem to play out differently around the globe. Western journalists are generally less supportive of any active promotion of particular values, ideas and social change, and they adhere more to universal principles in their ethical decisions. Journalists from non-western contexts, on the other hand, tend to be more interventionist in their role perceptions and more flexible in their ethical views.

Contraintes et conditions d’émergence de l’engagement des jeunes en situation de marginalité

Cette recherche doctorale vise à comprendre et interpréter les conditions d’émergence d’un engagement chez des jeunes en situation de marginalité. Des études ont montré que cette situation peut-être un frein important à l’engagement, en raison d’un manque de ressources personnelles, organisationnelles, ou culturelles. Généralement, on a tendance à insister sur le fait que « les jeunes » ne veulent plus militer. Pourtant, d’importantes actions collectives (mouvements étudiants ou communautaires) ou initiatives citoyennes personnelles (écriture de blogues ou signature de pétitions) viennent contredire cette affirmation. En fait, certaines prises de position, dans la sphère privée notamment, échappent à toute analyse classique et sont prises pour un non-engagement, de l’individualisme voire de l’apathie. À partir d’une approche qualitative, exploratoire et interprétative, le dispositif méthodologique de cette thèse privilégie l’observation participante et les entretiens de groupe afin de recueillir le point de vue des jeunes et d’observer un certain nombre d’actions collectives. C’est par le truchement d’organismes communautaires de jeunesse (OCJ) montréalais qu’une centaine de jeunes ont été rencontrés, de septembre 2010 à décembre 2011. L’analyse itérative du corpus de données s’est inspirée des principes de la théorisation ancrée (grounded theory). Un premier niveau d’analyse descriptive a permis de mettre en exergue les contraintes et les conditions d’émergence de l’engagement ainsi que les performances des jeunes en situation de marginalité. Les différentes formes d’engagement ont ensuite été explorées puis mises en perspective dans différents espaces : « original », « intermédiaire » et « négatif ». L’espace original correspond, dans cette thèse, aux moyens d’actions traditionnels (vote, militantisme politique). Nos résultats montrent que le positionnement des jeunes dans ce cadre est très tranché. En fait, non seulement ces modes d’actions émergent rarement mais, s’ils existent, sont le plus souvent soutenus par des intervenants. Dans un autre espace, les jeunes développent parfois des postures particulières, plus radicales ou, au contraire, des postures de retrait, de non-engagement. Cela se rapporte à ce qu’il conviendrait d’appeler l’espace négatif. Dans ce cas, les contraintes de la situation de marginalité poussent certains jeunes à mettre à distance l’engagement et à se situer aux marges des espaces de participation. L’opposition à toutes formes traditionnelles d’engagement amène des jeunes à envisager des moyens d’action plus radicaux que l’on peut également circonscrire dans cet espace négatif. On trouve au final une tout autre dynamique selon laquelle des jeunes prennent position au sein de ce que l’on a appelé l’espace intermédiaire. Les territoires et les modes d’action sont alors aussi éclectiques que la rue, l’entourage personnel, ou la création artistique underground. Si les rapports à l’engagement des jeunes rencontrés sont complexes, parfois ambivalents, ils révèlent toutefois la recherche d’une alternative, la construction de modes d’action particuliers. Une analyse dynamique des contraintes et des conditions d’émergence de l’engagement des jeunes en difficulté montre que leurs prises de position dépassent la simple dialectique engagement/non-engagement. Ainsi, ce que l’on pourrait appeler un « alter-engagement » se dessine à travers les prises de position de ces jeunes, particulièrement au sein de l’espace intermédiaire. Ce concept est développé pour mettre en évidence les formes d’engagement plus intimes, plus communautaires ou plus artistiques. L’alter-engagement se définit alors comme une forme de prise de position critique, impolitique, en réaction à la fois à l’engagement traditionnel, à une posture de retrait et à une posture plus radicale.

O envolvimento do departamento de compras no processo de contratação de serviços profissionais

A teoria sobre a atividade de Compras argumenta que as empresas deveriam delegar para esta área a atividade de adquirir insumos e serviços. O objetivo é obter competitividade sem perder a qualidade, através da competência e especialidade desta área. Em muitas empresas, esta área não é envolvida em todas as situações de processos de contratação. Poucos artigos e trabalhos publicados estudam a relação do cliente interno com o Departamento de Compras. Esta tese de doutorado tem como objetivo identificar os problemas que interferem no envolvimento do departamento de Compras, em processos de aquisição de serviços profissionais. A Teoria da Agência é utilizada como suporte teórico, por ser uma relação de um Principal, o cliente interno, e um Agente, o departamento de Compras. As hipóteses testadas verificaram se o envolvimento do Departamento de Compras difere por categoria de Compras e se tem relação com as premissas da Teoria da Agência. A pesquisa quantitativa teve 519 respostas de empresas nacionais e multinacionais no Brasil, de diversos setores da Economia. (367 de clientes internos e 152 de profissionais de Compras). Escalas utilizadas em trabalhos anteriores foram validadas, e os dados foram analisados a partir dos resultados da Análise de variância e de Regressão múltipla. O questionário foi disponibilizado na internet para os clientes internos do Departamento de Compras, com objetivo de focar nas razões do não envolvimento do departamento. Os resultados indicam que, na percepção dos clientes internos o envolvimento do departamento de Compras difere por tipo de serviço profissional. A relação entre as dimensões de envolvimento com as premissas da Teoria da Agência foi confirmada. As respostas recebidas dos profissionais de Compras confirmam que as percepções sobre o envolvimento do departamento de Compras diferem, ao comparar com as respostas dos clientes internos. A contribuição teórica foi de utilizar a Teoria da agência para estudos de problemas na cadeia de suprimentos, além da validação das escalas e a produção de pesquisa especificamente em categorias não relacionadas à produção. No campo gerencial, os resultados obtidos explicam a relação existente entre as quatro dimensões do envolvimento e a Teoria da Agência e são apresentadas as diferenças do envolvimento pela categoria a ser contratada.

The reporting quality of randomized controlled trials in orthodontics.

OBJECTIVES Accurate trial reporting facilitates evaluation and better use of study results. The objective of this article is to investigate the quality of reporting of randomized controlled trials (RCTs) in leading orthodontic journals, and to explore potential predictors of improved reporting. METHODS The 50 most recent issues of 4 leading orthodontic journals until November 2013 were electronically searched. Reporting quality assessment was conducted using the modified CONSORT statement checklist. The relationship between potential predictors and the modified CONSORT score was assessed using linear regression modeling. RESULTS 128 RCTs were identified with a mean modified CONSORT score of 68.97% (SD = 11.09). The Journal of Orthodontics (JO) ranked first in terms of completeness of reporting (modified CONSORT score 76.21%, SD = 10.1), followed by American Journal of Orthodontics and Dentofacial Orthopedics (AJODO) (73.05%, SD = 10.1). Journal of publication (AJODO: β = 10.08, 95% CI: 5.78, 14.38; JO: β = 16.82, 95% CI: 11.70, 21.94; EJO: β = 7.21, 95% CI: 2.69, 11.72 compared to Angle), year of publication (β = 0.98, 95% CI: 0.28, 1.67 for each additional year), region of authorship (Europe: β = 5.19, 95% CI: 1.30, 9.09 compared to Asia/other), statistical significance (significant: β = 3.10, 95% CI: 0.11, 6.10 compared to non-significant) and methodologist involvement (involvement: β = 5.60, 95% CI: 1.66, 9.54 compared to non-involvement) were all significant predictors of improved modified CONSORT scores in the multivariable model. Additionally, median overall Jadad score was 2 (IQR = 2) across journals, with JO (median = 3, IQR = 1) and AJODO (median = 3, IQR = 2) presenting the highest score values. CONCLUSION The reporting quality of RCTs published in leading orthodontic journals is considered suboptimal in various CONSORT areas. This may have a bearing in trial result interpretation and use in clinical decision making and evidence- based orthodontic treatment interventions.

Sitting on the fence: Swedish defence policy and the Baltic Sea region. OSW Point of View Number 33, April 2013

Sweden finds itself in the midst of the most heated debates about defence policy and the direction of military reforms since the end of the Cold War, as Stockholm faces the challenge of finding a new military security formula. From the Swedish point of view, the post-Cold War strategic timeout in Europe is coming to an end. The international environment is reverting to a situation in which the use of force among states is no longer an improbable scenario. Stockholm cannot rule out the emergence of crises or conflicts in Northern Europe in the future, which could directly or indirectly affect Sweden. In this context, the transformations of Sweden’s defence policy over the past twenty years have become a problem. Sweden has moved from neutrality, i.e. non-involvement on any side of an armed interstate conflict, to non-alignment, whereby it stays outside military alliances and freely shapes its policies during wartime. It has joined the European Union and co-operates closely with NATO on foreign missions. Its ability to defend its own territory, however, has diminished.

An essential partner in the background. Europe in China's policy during the rule of Xi Jinping. OSW STUDIES 56 2016

Chinese elites do not treat Europe as an equal partner and are convinced that China holds the upper hand over Europe. They see a growing asymmetry in bilateral relations. China’s sense of its own potential is boosted by internal divisions within the European Union. At the same time, Europe is China’s key economic partner and an ‘economic pillar’ supporting China’s growth on the international stage. Beijing strives to maintain Europe’s open attitude towards the Chinese economy, in particular its exports, technology transfer to China, location of investments and diversification of China’s currency reserves. Cooperation with Europe and support from Europe are necessary to enable China to improve its position in the international economic and financial system, mainly in order to legitimise China’s actions in the area of multilateralism and global governance. Similarly, Beijing attaches great importance to maintaining Europe’s non-involvement in two issues: China’s core interests and Chinese-American relations.

Involvement of pituitary gonadotropins, gonadal steroids and breeding season in sex change of protogynous dusky grouper, Epinephelus marginatus (Teleostei: Serranidae), induced by a non-steroidal aromatase inhibitor

Two experiments were performed using the aromatase inhibitor (AI) letrozole (100mg/kg) to promote sex change, from female-to-male, in protogynous dusky grouper. One experiment was performed during the breeding season (spring) and the other at the end of the breeding season (summer). During the spring, AI promoted sex change after 9weeks and the sperm produced was able to fertilize grouper oocytes. During the summer, the sex change was incomplete; intersex individuals were present and sperm was not released by any of the animals. Sex changed gonads had a lamellar architecture; cysts of spermatocytes and spermatozoa in the lumen of the germinal compartment. In the spring, after 4weeks, 11ketotestosterone (11KT) levels were higher in the AI than in control fish, and after 9weeks, coincident with semen release, testosterone levels increased in the AI group, while 11KT returned to the initial levels. Estradiol (E2) levels remained unchanged during the experimental period. Instead of decreasing throughout the period, as in control group, 17 α-OH progesterone levels did not change in the AI-treated fish, resulting in higher values after 9weeks when compared with control fish. fshβ and lhβ gene expression in the AI animals were lower compared with control fish after 9weeks. The use of AI was effective to obtain functional males during the breeding season. The increase in androgens, modulated by gonadotropins, triggered the sex change, enabling the development of male germ cells, whereas a decrease in E2 levels was not required to change sex in dusky grouper. © 2013 Elsevier Inc.

[Non-oculomotor eye involvement in Moebius sequence]

Moebius sequence is a congenital disorder that not only affects the oculomotor system but also the eyes themselves. Ocular involvement might be sight-threatening and needs regular follow-up by an ophthalmologist.

Genetic evidence for the involvement of DNA ligase IV in the DNA-PK-dependent pathway of non-homologous end joining in mammalian cells

Cells of vertebrates remove DNA double-strand breaks (DSBs) from their genome predominantly utilizing a fast, DNA-PKcs-dependent form of non-homologous end joining (D-NHEJ). Mutants with inactive DNA-PKcs remove the majority of DNA DSBs utilizing a slow, DNA-PKcs-independent pathway that does not utilize genes of the RAD52 epistasis group, is error-prone and can therefore be classified as a form of NHEJ (termed basic or B-NHEJ). We studied the role of DNA ligase IV in these pathways of NHEJ. Although biochemical studies show physical and functional interactions between the DNA-PKcs/Ku and the DNA ligase IV/Xrcc4 complexes suggesting operation within the same pathway, genetic evidence to support this notion is lacking in mammalian cells. Primary human fibroblasts (180BR) with an inactivating mutation in DNA ligase IV, rejoined DNA DSBs predominantly with slow kinetics similar to those observed in cells deficient in DNA-PKcs, or in wild-type cells treated with wortmannin to inactivate DNA-PK. Treatment of 180BR cells with wortmannin had only a small effect on DNA DSB rejoining and no effect on cell radiosensitivity to killing although it sensitized control cells to 180BR levels. This is consistent with DNA ligase IV functioning as a component of the D-NHEJ, and demonstrates the unperturbed operation of the DNA-PKcs-independent pathway (B-NHEJ) at significantly reduced levels of DNA ligase IV. In vitro, extracts of 180BR cells supported end joining of restriction endonuclease-digested plasmid to the same degree as extracts of control cells when tested at 10 mM Mg2+. At 0.5 mM Mg2+, where only DNA ligase IV is expected to retain activity, low levels of end joining (∼10% of 10 mM) were seen in the control but there was no detectable activity in 180BR cells. Antibodies raised against DNA ligase IV did not measurably inhibit end joining at 10 mM Mg2+ in either cell line. Thus, in contrast to the situation in vivo, end joining in vitro is dominated by pathways with properties similar to B-NHEJ that do not display a strong dependence on DNA ligase IV, with D-NHEJ retaining only a limited contribution. The implications of these observations to studies of NHEJ in vivo and in vitro are discussed.

Direct versus indirect channels: Differentiated loss aversion in a high‐involvement, non‐frequently purchased hedonic product

Purpose – This article aims to investigate whether intermediaries reduce loss aversion in the context of a high-involvement non-frequently purchased hedonic product (tourism packages). Design/methodology/approach – The study incorporates the reference-dependent model into a multinomial logit model with random parameters, which controls for heterogeneity and allows representation of different correlation patterns between non-independent alternatives. Findings – Differentiated loss aversion is found: consumers buying high-involvement non-frequently purchased hedonic products are less loss averse when using an intermediary than when dealing with each provider separately and booking their services independently. This result can be taken as identifying consumer-based added value provided by the intermediaries. Practical implications – Knowing the effect of an increase in their prices is crucial for tourism collective brands (e.g. “sun and sea”, “inland”, “green destinations”, “World Heritage destinations”). This is especially applicable nowadays on account of the fact that many destinations have lowered prices to attract tourists (although, in the future, they will have to put prices back up to their normal levels). The negative effect of raising prices can be absorbed more easily via indirect channels when compared to individual providers, as the influence of loss aversion is lower for the former than the latter. The key implication is that intermediaries can – and should – add value in competition with direct e-tailing. Originality/value – Research on loss aversion in retailing has been prolific, exclusively focused on low-involvement and frequently purchased products without distinguishing the direct or indirect character of the distribution channel. However, less is known about other types of products such as high-involvement non-frequently purchased hedonic products. This article focuses on the latter and analyzes different patterns of loss aversion in direct and indirect channels.

Discrimination or Differential Involvement? A Review of the Research Exploring the Impact of Indigenous Status on Sentencing

Existing court data suggest that adult Indigenous offenders are more likely than non-Indigenous defendants to be sentenced to prison but once imprisoned generally receive shorter terms. Using findings from international and Australian multivariate statistical analyses, this paper reviews the three key hypotheses advanced as plausible explanations for these differences: 1) differential involvement, 2) negative discrimination, 3) positive discrimination. Overall, prior research shows strong support for the differential involvement thesis, some support for positive discrimination and little foundation for negative discrimination in the sentencing of Indigenous defendants. Where discrimination is found, we argue that this may be explained by the lack of a more complete set of control variables in researchers’ multivariate models.
