Previous literature demonstrated that people spontaneously engage in systematic ways of thinking about biology. However, with most studies focusing on the western population, little is known about the universal nature of these cognitive frameworks. The current study used a construal-based survey to systematically test intuitive biology thinking in China. Overall, Chinese 8th graders demonstrated stronger essentialist thinking, weaker anthropocentric thinking, and similar level of teleological thinking compared to the US counterparts.

We herein describe a Ni-catalyzed multicomponent coupling reaction of alkyl halides, isocyanides, and H2O to access alkyl amides. Bench-stable NiCl2(dppp) is competent to initiate this transformation under mild reaction conditions, thus allowing easy operation and adding practical value. Substrate scope studies revealed a broad functional group tolerance and generality of primary and secondary alkyl halides in this protocol. A plausible catalytic cycle via a SET process is proposed based on preliminary experiments and previous literature.

AbstractThe concept of User Experience (UX) dates back to the 1990s, but a shared definition of UX is not available. As design integrates UX, different interpretations thereof can complicate the possibility to build upon previous literature and develop the field autonomously. Indeed, by analysing the literature, UX emerges as a cauldron of related and closely linked concepts. However, it is possible to find recurring attributes that emerge from those definitions, which are ascribable to two foci: the fundamental elements of the interaction (user, system, context) and typologies of experience (ergonomic, cognitive, and emotional). Those are used to build a framework. We have preliminarily investigated how UX is dealt with in design by mapping a sample of UX-related experimental articles published in design journals. We classified UX case studies based on the framework to individuate the UXs that emerge most frequently and the most studied ones in the design field. The two-focus framework allows the mapping of experiments involving UX in design, without highlighting specific favorable combinations. However, comprehensive studies dealing with all elements and UX typologies have not been found.

AbstractThe paper’s intention is to provide the correspondence of the globalization and the diversity in the management in this current trade era. The aim of the article is to understand the leader’s role in diversity management which is rapidly changing the global trade market more clearly. Globalization has a very big influence on the diversity management these days, both directly and indirectly. This study is based on a systematic review of 14 journal articles presented on the concerned topic. It is divided into three main parts: the paper describes benefits of diversity management, leader’s role and the challenges which leaders face while playing the role in the diverse management. In the review, it was found that “diversity” in the workplace is one of the most important factors to run the business or corporation smoothly and workplaces are truly benefitted by the management of the diversity. It works as an “aid to trade” in the performance of the workforce in the corporate culture. Next, we explained the challenges which leaders face and how to avoid those by taking initial steps. The paper ends up by providing discussions, limitations of the previous literature and some suggestions to the future researchers.

Courtyard House

Ludwig Mies van der Rohe's idea of a modern courtyard house is explored in this article considering three aspects: context stimuli, development, and practical applications. In this manner, this article provides significant contributions to the understanding of Mies's courtyard house idea. In fact, so far the stimuli and motivations behind his studies on this house type have been insufficiently explored. This obscurity has facilitated hypotheses such as that some of the courtyard house projects that Mies attributed to himself were not designed by him, but by his students and assistants. This article offers an alternative view of this issue that supports the architect's original claims by clarifying his teaching approach, creative process, and historical context. This article also clarifies the development of Mies's courtyard house idea through several projects that he designed on this theme, including the Courtyard House with Round Skylight (1934), which has been little explored in previous literature. Ultimately, this article examines the practical applications of Mies's courtyard house idea, both as a motif of student exercise and as an architectural solution for low dwellings, showing that this idea has maintained its relevance throughout the decades.

Abstract Language users have preferences for the connectives they choose to express causal relations. These choices may depend on the subjectivity involved in the relation. Dutch connectives illustrate this situation clearly: want (‘since/for’) is preferred typically for expressing subjective relations and omdat (‘because’) for objective ones. While various corpus-based studies have revealed a similar pattern in other languages, little attention has been paid to Spanish from this perspective. Recent corpus-based studies analyzed the connectives porque (‘because’), ya que (‘since’) and puesto que (‘given that’) using two different methods of analysis. Surprisingly, the findings did not coincide with the previous literature on Spanish connectives, and the semantic profile of such connectives in terms of subjectivity remained unclear. The current study again aims to investigate whether these connectives show systematic variation in terms of subjectivity, using crowdsourcing experimentation. Results show that Spanish native speakers prefer puesto que over porque to express subjective relations. However, no statistically significant difference was observed between porque and ya que. This study offers a better understanding of Spanish connectives in terms of subjectivity. Furthermore, it contributes to the assessment of the use of crowdsourcing as a useful and reliable method to elucidate the meaning and use of connectives.

ABSTRACTOne effect of pressure on elements and compounds is to decease their interatomic distances, which can bring about dramatic perturbations in their electronic nature and bonding, which can be reflected in changes in physical and/or chemical properties. One important issue in the actinide series of elements is the effect of pressure on the 5f-electrons. We have probed changes in electronic behavior with pressure by monitoring structure by X-ray diffraction, and have studied several actinide metals and compounds from thorium through einsteinium. These studies have employed angle dispersive diffraction using synchrotron radiation, and energy dispersive techniques via conventional X-ray sources. The 5f-electrons of actinide metals and their alloys are often affected significantly by pressure, while with compounds, the structural changes are often not linked to the involvement of 5 f-electron. We shall present some of our more recent findings from studies of selected actinide metals, alloys and compounds under pressure. A discussion of the results in terms of the changes in electronic configurations and bonding with regard to the element's position in the series is also addressed.

Purpose – The purposes of this study are to identify, classify and prioritize knowledge management (KM) barriers in an Iranian project-based organization (PBO) and to present a conceptual framework for improving attitudes to KM in the Iranian context. Design/methodology/approach – After studying previous literature on the topic, initial barriers of KM in PBOs were extracted. Then, a list of barriers of KM in the aforementioned organizations was finalized by interviewing experts in KM. After that, the barriers were prioritized using a questionnaire. Finally, a conceptual framework for successfully tackling KM barriers was presented. Findings – In this article, barriers of KM in PBOs have been divided into five categories: individual, organizational, technological, contextual, and inter-project. Then a three-layered conceptual framework has been presented which describes how the barriers of KM in PBOs may be removed progressively. Practical implications – The prepared and prioritized list of barriers of KM in PBOs is a stepping stone and a guideline for managers in PBOs which will enable them to identify barriers of KM in their own organizations and resolve them and improve KM in their organizations. It also serves as a useful base for researchers to expand further research concerning barriers of KM in PBOs. Originality/value – This article is probably the first article which has identified barriers of KM via interviews and questionnaires carried out in 50 active PBOs which had a KM section. The article also presents a three-layered framework for lowering barriers of KM, which can be applied step by step after considering the level of importance of each one identified.
