L’ambivalence dans la décision d’acheter des produits de luxe : le cas des millennials
Authors: Ladwein Richard , Sánchez Andrea 
Published: February 2019

Le luxe est associé à l’excès mais aussi à la beauté et au plaisir. Il éveille souvent des réactions à la fois favorables et défavorables parmi les consommateurs, en particulier chez les jeunes ou millennials . Cette catégorie de la population, généralement négligée dans les études sur le luxe, représente pourtant un levier potentiel de croissance pour les marques de luxe. Par ailleurs, ce segment représente l’avenir dans le sens où il sera au cœur du marché du luxe des adultes de demain. Les enjeux sont donc importants. Ce segment des millennials pourrait en effet éprouver des sentiments d’ambivalence face à la décision d’acheter des produits de luxe et cela pourrait influencer son intention de faire des achats et de les reporter. L’impact de l’ambivalence sur ces variables est mal connu dans la littérature en marketing. En effet, les études sur les attitudes envers les produits et marques de luxe utilisent des échelles qui mesurent les attitudes favorables ou défavorables mais qui ne permettent pas aux consommateurs d’exprimer leur ambivalence. Afin d’expliquer comment l’ambivalence influe sur la décision d’acheter des produits de luxe, nous avons mené une enquête par questionnaire auprès de 143 étudiants français. Les résultats montrent que l’ambivalence a un double effet sur les intentions de ce nouveau segment de consommateurs : elle atténue l’intention d’achat par le biais de l’attitude, et favorise le report d’achat par le biais de la recherche d’informations.
Xénophon et les grâces du pouvoir
Authors: Azoulay Vincent 
Published: February 2019

Profondément déçu par les institutions civiques de son temps, Xénophon est à la recherche, dans ses écrits, d'hommes exceptionnels dont le pouvoir pourrait résister aux assauts du temps et assurer la sérénité des notables. Cette quête d'un chef idéal, souvent mélancolique, parfois désabusée, donne à l'œuvre de Xénophon l'un de ses fils directeurs : l'auteur élabore une construction intellectuelle complexe qui privilégie le charisme de l'homme providentiel sur les formes de domination légales ou traditionnelles. Dans l'oeuvre de Xénophon, le charisme ne relève pas d'une séduction ineffable, mais se construit autour de procédures et de techniques qui se laissent saisir à travers le concept protéiforme de charis - la grâce. Une telle notion, dont les connotations touchent à la sphère du don et de l'échange comme à celle de l'éclat et du charme, permet d'analyser ces pratiques en les resituant dans l'épaisseur de leur contexte social et culturel.

Un tel parti-pris rend possible une approche transversale de l'autorité, dans la tradition d'une anthropologie politique raisonnée. Avec la charis comme fil d'Ariane, le pouvoir d'un commandant d'armée ou celui d'un roi puissant peut être utilement comparé à l'autorité du chef d'oikos sur sa maisonnée, voire à l'ascendant de Socrate sur ses disciples : aux yeux de Xénophon, l'ensemble de ces pouvoirs repose sur les mêmes fondements « charismatiques ». Le politique ainsi conçu, loin de se limiter à des principes abstraits, s'élargit dès lors à l'étude des pratiques sociales et culturelles pour ouvrir, en définitive, sur une histoire des émotions. Ainsi voit le jour une réflexion non institutionnelle sur l'autorité et ses mécanismes.
Le complexe de Zeus
Authors: Bonnard Jean-Baptiste 
Published: February 2019

Les Grecs paraissent avoir conçu le monde idéal sans femmes. Pour résoudre la contradiction entre l’utopie d’un monde exclusivement masculin et la nécessaire présence des femmes pour perpétuer l’espèce, ils ont produit au moins deux types de discours relatifs à la paternité : des mythes donnant à voir un rêve, celui d’une paternité exclusive qui évincerait les femmes de leur pouvoir de reproduction ; des théories biologiques depuis les Présocratiques jusqu’à Aristote, qui, tout en admettant, à des degrés divers et sous des modalités variables, la participation des femmes au processus de génération, déprécient cependant la maternité au profit de la paternité. Ces deux formes de représentations mettent en évidence le phantasme de pouvoir se reproduire seul, ce que l’on peut appeler le complexe de Zeus, tant ce dieu semble en avoir été particulièrement investi. Ce complexe, dans lequel s’exprime une volonté de puissance par le déni de la maternité, manifeste que les Grecs ont pensé la paternité sous la catégorie du pouvoir.
Perceptions of sacrifice, workplace friendship and career concerns as explanatory mechanisms of employees’ organisational commitment
Authors: Coetzee Melinde , Ferreira Nadia , Potgieter Ingrid 
Published: February 2019

Orientation: Employees’ psychological attachment to their organisation remains an important topic of inquiry for organisations concerned about improving their talent management practices for the purpose of retaining valuable human capital.Research purpose: The aim of the study was to explore the constructs of job-embedded sacrifice, workplace friendship and career concerns as potential underlying explanatory mechanisms of employees’ affective, continuance and normative commitment towards the organisation. Organisational attachment theory was utilised as theoretical framework to study the relations among the variables.Motivation for the study: The notion of job-embedded sacrifice, workplace friendship, career concerns as explanatory mechanisms of employees’ affective, continuance and normative commitment in the South African higher education context is under-researched, and especially from the perspective of organisational attachment theory.Research approach/design and method: A non-probability convenience sample (N = 200) of academic and administrative staff members employed in a South African higher educational institution participated in the study. A cross-sectional, quantitative research design approach was followed. Multiple regression analysis was performed.Main findings: Person–job sacrifice positively predicted affective, continuance and normative commitment. Perceptions of friendship opportunity accounted for the variance in affective commitment. High levels of work–life adjustment career concerns accounted for higher levels of affective and normative commitment.Practical/managerial implications: Addressing the underlying psychological needs espoused by employees’ perceptions of person–job sacrifice, friendship opportunity and work–life adjustment concerns are important to consider in human resource talent management practices. The constructs speak to employees’ sense of employment security which influences their organisational commitment.Contribution/value-add: The study extends organisational attachment theory by offering insight into the role of person–job sacrifice, friendship opportunity in the workplace and work–life adjustment concerns in explaining employees’ organisational commitment. The new insights inform human resource retention practices for academic and administrative staff members in the higher education environment.
Evaluation of remuneration preferences of knowledge workers
Authors: Bussin Mark H.R. , Brigman Natasha 
Published: February 2019

Orientation: This research evaluates the remuneration preferences of knowledge workers as a retention strategy in an integrated international energy and chemical company, using the WorldatWork Total Rewards Model.Research purpose: Organisations may benefit from understanding their employees’ preferential remuneration benefits, in particular, knowledge workers as a scare skill requiring specific retention strategies.Motivation for the study: To understand the remuneration preferences for the retention of a group of knowledge workers within a large organisation based in South Africa. The research is necessary within organisations in South Africa impacted by scarce skills and a need to attract and retain knowledge workers. If remuneration preferences are not considered as part of retention, there is a risk knowledge workers may leave for preferential opportunities.Research approach/design and method: A total of 199 employees from a group of 1229 voluntarily participated in the survey. An electronic-based questionnaire was developed from the WorldatWork rewards model. The results from the surveys were analysed with descriptive statistics and inferential statistics.Main findings: No significance in reward strategies was found for age, level of performance or number of years of service. There was also no significant difference between the knowledge workers number of years of service and their intention to remain with the organisation. There was a significance in gender for benefits, flexibility and performance development preferences.Practical/managerial implications: The development of retention strategies should consider reward preferences of male and female employees.Contribution/value-add: Knowledge workers’ reward preferences do not differ on demographic variables, except gender. This contradicts some literature in the area.
The Misinformed Versus the Misunderstood
Authors: Heo Isaac 
Published: February 2019

The Youth Criminal Justice Act (YCJA) came into effect in 2003 as a response to the overincarceration of youth that occurred under its predecessor, the Young Offender’s Act (YOA). Parliament’s intention was clear in repealing and replacing the YOA in favour of the more restorative YCJA: no longer would custody be considered an appropriate response to youth crime. More than a decade has passed since the introduction of the YCJA, and statistics reveal that it has had incredible success in reducing the rate of overall youth incarceration. What remains problematic, however, is the persistent and prevailing issue of the overincarceration of Indigenous youth.
The purpose of this article is to unpack the complexity of this issue, identify its causes, and to ultimately propose different strategies to help reduce a custodial response to Indigenous youth crime. In achieving this goal, the article will begin with an overview of the YCJA and an exploration of its restorative provisions to argue that the legislation itself is not at fault. The article will then provide current statistics on the overincarceration of Indigenous youth, and subsequently, examine some of the most popular explanations as to why the issue continues to persist. Finally, and perhaps most importantly, the article will conclude by proposing several strategies – such as the implementation of more Aboriginal Youth Courts – to better address the overincarceration of Indigenous youth moving forward.
Runaway Jurors
Authors: Hogg Keith W 
Published: February 2019

This paper considers the impact of out-of-court research by jurors on trial fairness and policies to deter such independent research. Though jurors are barred from considering evidence outside the courtroom, some recent Canadian cases show that independent research occurs nonetheless. Part I of the paper reviews the policy rationales for the ban on juror research. Part II discusses the prevalence of independent research and reviews some recent Canadian cases in which the issue is addressed. Part III considers solutions to the problem including the approaches taken by the UK and throughout the US. The paper concludes by recommending that Canada act pre-emptively to deter independent juror research before resorting to criminal prosecution of so-called "runaway jurors."
A Cognição Histórica Situada e os critérios de avaliação de Manuais Didáticos no Brasil
Authors: Schmidt Maria Auxiliadora 
Published: February 2019

A investigação abrange a análise qualitativa dos critérios para avaliação de manuais de História do Ensino Médio, propostos pelo governo brasileiro no documento Edital de Convocação PNLD 2015 para 2018. Adotou-se a metodologia de investigação qualitativa de estudo no caso e alguns elementos da análise de conteúdo na investigação bibliográfica e documental. A questão fundamental que norteou o percurso da investigação foi verificar se, entre os critérios de avaliação de manuais didáticos brasileiros, foram incorporados elementos relacionados à aprendizagem cuja natureza baseia-se na "cognição histórica situada". No sentido de definir o espectro empírico da investigação foram selecionados, para análise, os critérios utilizados no processo de avaliação dos manuais de História destinados aos alunos do Ensino Médio, cuja faixa etária situa-se, principalmente, entre 15 a 17 anos de idade. A categorização dos dados foi realizada a partir daqueles propostos para a área de Ciências Humanas e, também, mais especificamente, para História. As categorias foram selecionadas tendo como norte o referencial teórico adotado e podem ser sintetizadas em: 1. Orientação temporal; 2. Multiperspectividade; 3. Trabalho com fontes. Observou-se que a lacuna de conceituação do que é “pensamento histórico”, bem como os critérios adotados, indicam mais uma preocupação com aspectos metodológicos e conceituais da área de Ciências Humanas, do que uma delimitação mais explicita de critérios que pudessem balizar uma obra didática cujo objetivo seria aprender a pensar historicamente. Acredita-se que a explicitação de critérios formadores do pensamento histórico poderiam qualificar, de forma mais objetiva, a aprendizagem e, portanto, o ensino de História, em direção a uma literacia histórica, que colocasse o jovem aluno do Ensino Médio como cidadão do mundo e do seu tempo.

Authors: Cilia Tancredi , Bertetta Daniele , Gualeni Paola , Tani Giorgio , Viviani Michele 
Published: February 2019

Additive manufacturing (AM), or three dimensional printing, is a modern way to build objects with possibly a high degree of accuracy and favorable cost/benefit ratio. This approach is widely used by many manufacturing industries and a certain interest for this innovative production technology is also growing in the ship design and production field. To this regard, the experimental activity at the model scale is often necessary for the ship performance assessment in the design phase. In the article, preliminary results of a propeller model for the cavitation tunnel, built with additive technology, are presented, showing the strengths and weaknesses of the printed model. Moreover, as an introductive overview, different AM technologies are briefly described, with the aim to point out potential applicability to ships.

1. Introduction
Additive Manufacturing (AM), also known as 3D printing, is a well-known process to shape objects by layering materials under numerical control until the completion of the work. It represents an innovative approach because it is based on the addition of material instead of carving material from a block (like CNC—Computer Numerical Control, i.e. a manufacturing approach relying on mills, drills, and other numerically controlled tools). AM is deemed as an outstanding flywheel for innovation in the productive world, and the shipbuilding industry seems to have started realizing the advantages of this technology, already largely used, e.g., in the automotive, aerospace, biomedical, and energy industries (Shahi 2016; Satish Prakasha et al. 2018).
In this perspective, an introductive overview of different AM typologies is presented in the article, to possibly understand how it could be used to improve ship design and production. The overview includes the applicable technologies, focusing on the printing process, the materials, and the mechanical properties of the final printed object. A practical example of AM technology application is presented regarding the printing of the blades of a ship's propeller model for experiments in a cavitation tunnel.

Проведен анализ научных публикаций и патентов, посвященных механохимическому синтезу неорганических носителей и катализаторов нефтеперерабатывающих процессов: крекинга, риформинга, гидроочистки и гидрокрекинга. Показано, что введение механической активации в технологический процесс синтеза неорганических носителей и катализаторов, как правило, приводит к повышению каталитической активности и селективности. Рассмотрены особенности механохимического синтеза сложных никель-молибденовых оксидов, которые являются предшественниками сульфидных никель-молибденовых катализаторов гидроочистки. Показано, что в условиях механической активации возможно получение никель-молибденового высокоактивного и термостабильного β-NiMoO4, в составе которого Мо находится в тетраэдрической конформации. Описана разработанная в ИППУ СО РАН технология получения высокодисперсных карбидсодержащих катализаторов с применением метода механической активации. Рассмотрены текстура и морфология синтезированных высокодисперсных массивных карбидсодержащих катализаторов. Показано, что размер активных частиц составляет 2–5 нм. Проведены модельные каталитические испытания и установлено, что карбидсодержащие высокодисперсные катализаторы проявляют высокую каталитическую активность в модельной реакции гидрообессеривания дибензотиофена.

Background music stints creativity: Evidence from compound remote associate tasks
Authors: Threadgold Emma , Marsh John E. , McLatchie Neil , Ball Linden J. 
Published: February 2019

SummaryBackground music has been claimed to enhance people's creativity. In three experiments, we investigated the impact of background music on performance of Compound Remote Associate Tasks (CRATs), which are widely thought to tap creativity. Background music with foreign (unfamiliar) lyrics (Experiment 1), instrumental music without lyrics (Experiment 2), and music with familiar lyrics (Experiment 3) all significantly impaired CRAT performance in comparison with quiet background conditions. Furthermore, Experiment 3 demonstrated that background music impaired CRAT performance regardless of whether the music induced a positive mood or whether participants typically studied in the presence of music. The findings challenge the view that background music enhances creativity and are discussed in terms of an auditory distraction account (interference‐by‐process) and the processing disfluency account.
