Systematic sampling of communities gives rise to large contingency tables summing up possible changes in the assemblages' structure. Such tables are generally analysed by multivariate statistical methods, which are ill-suited for simultaneously analysing rare and common species (Field et al., 1982). In order to separately process species belonging to either of these categories, we propose a statistical method to select common species in a sequence of ecological surveys. It is based on a precise definition of rarity, and depends on a (...) rarity parameter. In this work, this parameter will be optimised so that the sub-table of common species captures the essential features of the complete table as well as possible. In this way we analysed the spatio-temporal evolution of macrobenthic communities from the Algiers harbour to study the pollution influence during a year. The examination of the communities' structuring was done through Principal Components Analysis (PCA) of the species proportions table. Environmental variables were simultaneously sampled. We show that the data structure can be explained by about 25% of the total number of present species. Two environmental gradients were brought to the fore inside the harbour, the first one representing pollution, and the second one representing hydrological instabilities. (shrink)

Linguistic predictions may be generated from and evaluated against a representation of events and referents described in the discourse. Compatible with this idea, recent work shows that predictions about novel noun phrases include their definiteness. In the current follow-up study, we ask whether people engage similar prediction-related processes for definite and indefinite referents. This question is relevant for linguistic theories that imply a processing difference between definite and indefinite noun phrases, typically because definiteness is thought to require a uniquely identifiable (...) referent in the discourse. We addressed this question in an event-related potential (ERP) study (N = 48) with preregistration of data acquisition, preprocessing, and Bayesian analysis. Participants read Dutch mini-stories with a definite or indefinite novel noun phrase (e.g., “het/een huis,” the/a house), wherein (in)definiteness of the article was either expected or unexpected and the noun was always strongly expected. Unexpected articles elicited enhanced N400s, but unexpectedly indefinite articles also elicited a positive ERP effect at frontal channels compared to expectedly indefinite articles. We tentatively link this effect to an antiuniqueness violation, which may force people to introduce a new referent over and above the already anticipated one. Interestingly, expectedly definite nouns elicited larger N400s than unexpectedly definite nouns (replicating a previous surprising finding) and indefinite nouns. Although the exact nature of these noun effects remains unknown, expectedly definite nouns may have triggered the strongest semantic activation because they alone refer to specific and concrete referents. In sum, results from both the articles and nouns clearly demonstrate that definiteness marking has a rapid effect on processing, counter to recent claims regarding definiteness processing. (shrink)

The dynamics of the "Etang de Berre", a brackish lagoon situated close to the French Mediterranean sea coast, is strongly disturbed by freshwater inputs coming from an hydroelectric power station. The system dynamics has been described as a sequence of daily typical states from a set of physicochemical variables such as temperature, salinity and dissolved oxygen rates collected over three years by an automatic sampling station. Each daily pattern summarizes the evolution, hour by hour of the physicochemical variables. This article (...) presents results of forecasts of the states of the system subjected to the simultaneous effects of meteorological conditions and freshwater releases. We recall the main step of the classification tree method used to build up the predictive model (Classification and Regression Trees, Breiman et al., 1984) and we propose a transfer procedure in order to test the stability of the model. Results obtained on the Etang de Berre data set allow us to describe and predict the effects of the environmental variables on the system dynamics with a margin of error. The transfer procedure applied after the tree building process gives a maximum gain in prediction accuracy of about 15%. (shrink)

Biobanks are currently archiving human materials for medical research at a hitherto unprecedented rate. These valuable resources will be essential for developing ‘personalized’ medicines and for a better understanding of disease susceptibilities. However, for such scientific advances to benefit everyone, it is crucial that biobanks recruit donations from all sections of the community. Unfortunately, other initiatives, such as transplant programmes, have clearly demonstrated that ethnic minorities are under-represented. Here we suggest that this issue deserves serious consideration to avoid biobanks evolving (...) into ethnically biased archives which unwittingly promote race-specific research. Specifically, this necessitates research ethics committees engaging in a re-assessment of the relative merits of individual personal sovereignty and the common good. (shrink)

Spatial and temporal heterogeneity are often described as important factors having a strong impact on biodiversity. The effect of heterogeneity is in most cases analyzed by the response of biotic interactions such as competition of predation. It may also modify intrinsic population properties such as growth rate. Most of the studies are theoretic since it is often difficult to manipulate spatial heterogeneity in practice. Despite the large number of studies dealing with this topics, it is still difficult to understand how (...) the heterogeneity affects populations dynamics. On the basis of a very simple model, this paper aims to explicitly provide a simple mechanism which can explain why spatial heterogeneity may be a favorable factor for production. We consider a two patch model and a logistic growth is assumed on each patch. A general condition on the migration rates and the local subpopulation growth rates is provided under which the total carrying capacity is higher than the sum of the local carrying capacities, which is not intuitive. As we illustrate, this result is robust under stochastic perturbations. (shrink)

We introduce a two-valued and a three-valued truth-valuational substitutional semantics for the Quantified Argument Calculus (Quarc). We then prove that the 2-valid arguments are identical to the 3-valid ones with strict-to-tolerant validity. Next, we introduce a Lemmon-style Natural Deduction system and prove the completeness of Quarc on both two- and three-valued versions, adapting Lindenbaum’s Lemma to truth-valuational semantics. We proceed to investigate the relations of three-valued Quarc and the Predicate Calculus (PC). Adding a logical predicate T to Quarc, true of (...) all singular arguments, allows us to represent PC quantification in Quarc and translate PC into Quarc, preserving validity. Introducing a weak existential quantifier into PC allows us to translate Quarc into PC, also preserving validity. However, unlike the translated systems, neither extended system can have a sound and complete proof system with Cut, supporting the claim that these are basically different calculi. (shrink)

While business ethics has generated a great deal of research internationally over the last few decades, academic reviews of the business ethics literature remain limited. Moreover, there has been little attempt to date to analyze this literature specifically in the Greater China region, which has been experiencing rapid socioeconomic growth and dynamic evolution of business ethics in recent decades. This paper addresses this research gap by undertaking a comprehensive and critical appraisal of the business ethics literature on Greater China. In (...) particular, it maps out the existing research findings, identifies limitations in methodology, and suggests future directions for business ethics research in this region. The findings indicate that the scholarly interests cover 24 research themes, including corporate social responsibility and social performance; ethical beliefs, judgment, values, decision-making, and culture; workplace ethics and behavior; marketing ethics and consumer behavior; and sustainability. This review reveals a growing imbalance between empirical and conceptual/theoretical studies on business ethics. In addition, the published works covered in this review heavily rely on survey method and convenience sampling, with a predominant focus on a single individual level of analysis. Importantly, this study identifies four directions for future research: contextualized theoretical development, addressing multilevel research, developing research design tailored to the Chinese context, and ensuring more diversified and rigorous data collection.

Integrating stakeholder agency theory with the instrumental corporate social responsibility (CSR) literature, this study explores how award-winning CEOs consider personal interests and balance competing stakeholder demands when they decide between external and internal CSR, or CSR focus. Using a difference-in-differences research design, we find that after winning a prestigious media award, CEOs engage in more external CSR, which is more visible to the public, and less internal CSR, which is less likely to attract public attention. We find that such an (...) influence on CSR focus is more salient for award-winning CEOs with lower stock ownership (i.e. a stronger self-serving motivation) than for CEOs with higher stock ownership. Furthermore, we explore the role of stakeholder salience in modifying award-winning CEOs’ decisions about CSR focus. When external stakeholder salience is higher (e.g. higher media coverage), award-winning CEOs' manipulation of CSR focus by increasing external CSR and decreasing internal CSR is more salient. However, such effects can be dampened when internal stakeholder salience is higher (e.g. higher human capital intensity). Our study contributes to the instrumental CSR literature by demonstrating the underlying processes and boundary conditions of how awards affect CEOs' balance of stakeholder salience. (shrink)

This study develops an internal–external institutional framework that explains why firms act in socially responsible ways in the emerging country context of China. Utilizing a mixed method of in-depth interviews and a survey study of 225 Chinese firms, the author found that internal institutional factors, including ethical corporate culture and top management commitment, and external institutional factors, including globalization pressure, political embeddedness, and normative social pressure, will affect the likelihood of firms to act in socially responsible ways. In particular, implicit (...) ethical corporate culture plays a key role in predicting different aspects of corporate social responsibility, while external institutional mechanisms mainly predict market-oriented CSR initiatives. This study contributes to the research on CSR antecedents by showing that in the emerging economy of China, CSR toward nonmarket stakeholders is more closely intertwined with corporate tradition and values, while legitimacy-seeking CSR activities are still limitedly rewarded.

An increasing body of institutional research has examined organizations’ response to conflicting institutional logics, but few studies have looked into how cross-sector organizational actors experiencing institutional complexity strategize their response mechanisms to create value in the context of corporate social responsibility (CSR). We conduct a comparative case study of nine social partnerships between multinational companies (MNCs) and nonprofits in China. We identify a partnership logic among the value-creating partnerships where partners guided by an either/and mindset take joint ownership of the (...) social or sustainability issue/cause and integrate it into their core set of activities and goals. By contrast, the less successful partnerships guided by an either/or mindset pursue a substitution logic in which the issue and project are kept separate and marginalized from core activities and goals. We contribute to an understanding of the value creation of cross-sector social partnerships by revealing the institutional embeddedness of such partnerships and deriving a process model of collaborative value creation through institutional works in social partnerships.

This study investigates the antecedents and mechanisms of consumers’ adoption of a public bicycle-sharing scheme as a form of shared sustainable consumption. Drawing on marketing ethics and sustainability literature, it argues that cultural and consumption values drive or deter the adoption of PBSS through the mediating mechanism of ethical evaluation. This study tests its hypotheses using a sample of 755 consumers from one of the largest PBSS programs in China. The results confirm the significance of collectivism, man–nature orientation, materialism, and (...) face-consciousness as key determinants of the adoption of PBSS. Interestingly, these values play mixed roles in influencing PBSS adoption. It also finds that such values and beliefs need to be effectively translated into ethical evaluations of PBSS adoption, and need to be addressed in the specific social context. Thus, ethical evaluation constitutes a cognitive strategy that allows consumers to justify and defend their adoption of sustainability practices. The results suggest that a desirable sustainability program needs to not only cater to the cultural and psychological motivations of consumers, but also reflect the social norms and social context in which the sustainability practices and consumers are embedded.

Nowadays, emotions are among the most significant issues in the route of learning a language that should be taken into consideration. Consistent with the fundamental function of positive psychology and also the theory of broaden-and-build, enjoyment in language learning especially the foreign language is among those positive emotions that encourage EFL learners to develop their perspective to achieve. Efforts to apprehend and develop the academic achievement of EFL learners have also progressively concentrated on self-regulation as it boosts learners’ enjoyment, hope, (...) pride, self-control, and learning. Besides, in line with the investigations of these positive emotions, principles of PP, the present review makes every effort for the interplay and its effects in language learning. It is pertinent to state that the present review of studies can benefit academic organizations, professional development centers, policymakers in the academic community to consider the role of emotions, namely positive ones and their positive impact on language learning.

This study examines whether customer firms’ unethical behavior distorts suppliers’ investment decisions. Using litigation and restatement to measure unethical behavior, we find that suppliers with customers engaged in frauds tend to invest more during the cheating period, compared to unaffected suppliers. In cross-sectional analyses, we examine the moderating effect of suppliers’ reliance on customer information and peer information. Results show that more industry peers’ voluntary disclosures and analyst coverage, lower sales volatility, and lower relationship-specific investments mitigate the distortion effect on (...) suppliers. Suppliers’ overinvestments caused by customers’ misreporting also lead to the suppliers’ inferior future performance and subsequent negative market reaction, and the severity of customers’ misreporting influences the magnitude of suppliers’ investment distortions. These results are robust in a dynamic difference-in-difference specification, an SEC enforcement sample, and a sample that excludes observations for suppliers and customers in the same industry. This paper contributes to the ethics literature by emphasizing the importance of creditable supply-chain information transfer to investment decisions and clarifying the nontrivial influence of principal customers in the supply-chain network.

Distinct from nominal metaphors, predicate metaphors entail metaphorical abstraction from concrete verbs, which generally involve more action and stronger motor simulation than nouns. It remains unclear whether and how the concrete, embodied aspects of verbs are connected with abstract, disembodied thinking in the brains of L2 learners. Since English predicate metaphors are unfamiliar to Chinese L2 learners, the study of embodiment effect on English predicate metaphor processing may provide new evidence for embodied cognition and categorization models that remain controversial, and (...) offer practical insights into L2 metaphor processing and pedagogy. Hence, we aim to investigate whether the embodiment of verbs, via the activation of sensorimotor information, influences two groups of L2 learners during their comprehension of conventional and novel predicate metaphors. The results show a significant effect of embodiment: a stronger facilitation for novel predicate metaphors in both higher-level and lower-level groups, and a weaker facilitation for conventional predicate metaphors in the lower-level group. The findings demonstrate preliminary evidence for a graded effect of embodiment on predicate metaphors processing, modulated by L2 proficiency and metaphor novelty. The study supports a hybrid view of embodied cognition and reveals that sensorimotor aspects of verbs may be the intermediate entity involved in the indirect categorization. (shrink)
