CRISPR‐Cas technology accelerates development of fast, accurate, and portable diagnostic tools, typified by recent applications in COVID‐19 diagnosis. Parasitic helminths cause devastating diseases afflicting 1.5 billion people globally, representing a significant public health and economic burden, especially in developing countries. Currently available diagnostic tests for worm infection are neither sufficiently sensitive nor field‐friendly for use in low‐endemic or resource‐poor settings, leading to underestimation of true prevalence rates. Mass drug administration programs are unsustainable long‐term, and diagnostic tools – required to be (...) rapid, specific, sensitive, cost‐effective, and user‐friendly without specialized equipment and expertise – are urgently needed for rapid mapping of helminthic diseases and monitoring control programs. We describe the key features of the CRISPR‐Cas12/13 system and emphasise its potential for the development of effective tools for the diagnosis of parasitic and other neglected tropical diseases (NTDs), a key recommendation of the NTDs 2021–2030 roadmap released by the World Health Organization.

Relevant research shows teachers’ “psychological power” plays a more essential role in promoting their professional development compared with the powers provided by various external factors, and it is therefore held that exploring college English teachers’ individual psychological power is of great significance. To this end, this study investigated college English teachers’ psychological empowerment via the development and validation of CETPE’s scale. Based on our literature review on psychological empowerment and analysis of teachers professional development’s status quo, we made a working (...) definition of CETPE as a system involving perception of their occupation, sense of competence, experiencing of autonomy, judgment of their impact and understanding of their status. In our study, firstly the literature review and the interview with 17 college English teachers were adopted to conceptualize the dimensions of CETPE, and an exploratory factor analysis of data was conducted from 227 college English teachers and then the subsequent confirmatory factor analysis of data collected from another sample of 1030 generated 15 items belonging to five factors. The findings reveal that CETPE is systematically composed of teachers’ positive perception and experience of work meaningfulness, teaching autonomy, occupational competence, professional impact and social status. This study provides a new path for teachers’ professional development via strengthening their intrinsic driving force and thus helps improve the college English teaching effects. (shrink)

In this paper, we mainly investigate the existence of states based on the Glivenko theorem in bounded semihoops, which are building blocks for the algebraic semantics for relevant fuzzy logics. First, we extend algebraic formulations of the Glivenko theorem to bounded semihoops and give some characterizations of Glivenko semihoops and regular semihoops. The category of regular semihoops is a reflective subcategory of the category of Glivenko semihoops. Moreover, by means of the negative translation term, we characterize the Glivenko variety. Then (...) we show that the regular semihoop of regular elements of a free algebra in the variety of Glivenko semihoops is free in the corresponding variety of regular semihoops. Similar results are derived for the semihoop of dense elements of free Glivenko semihoops. Finally, we give a purely algebraic method to check the existence of states on Glivenko semihoops. In particular, we prove that a bounded semihoop has Bosbach states if and only if it has a divisible filter, and a bounded semihoop has Riečan states if and only if it has a semi-divisible filter.

With the idea of analyzing awareness as potential for knowledge, we propose a novel semantics for awareness logic. Expressivities of languages with different combinations of modalities for this semantics are investigated. We explore the properties of our semantics and compare our model with Fagin & Halpern model and the model by Heifetz et al. in partitional settings. A series of equivalence results are established from the comparison. Finally, we provide two axiomatizations for implicit knowledge and explicit knowledge, respectively, and prove (...) soundness and completeness for them. (shrink)

Many viruses evolved mechanisms for capping the 5′‐ends of their plus‐strand RNAs as a means of hijacking the eukaryotic messenger RNA (mRNA) splicing/translation machinery. Although capping is critical for replication, the RNAs of these viruses have other essential functions including their requirement to be packaged as either genomes or pre‐genomes into progeny viruses. Recent studies indicate that human immunodeficiency virus type‐1 (HIV‐1) RNAs are segregated between splicing/translation and packaging functions by a mechanism that involves structural sequestration of the 5′‐cap. Here, (...) we examined studies reported for other viruses and retrotransposons that require both selective packaging of their RNAs and 5′‐RNA capping for host‐mediated translation. Our findings suggest that viruses and retrotransposons have evolved multiple mechanisms to control 5′‐cap accessibility, consistent with the hypothesis that removal or sequestration of the 5′ cap enables packageable RNAs to avoid capture by the cellular RNA processing and translation machinery.

Compared with traditional technological innovation modes, green technology innovation is more targeted for low carbon development and critical support for countries worldwide to combat climate change. The impact of green technology innovation on carbon emissions is considered in terms of fixed effect and mediating effect models through industrial structure upgrading. For this purpose, the sample dataset of 30 provincial administrative areas in China from 2008 to 2020 is employed. The results demonstrate that green technology innovation exerts significantly inhibitory effects on (...) carbon emissions, whose conclusion still holds after removing municipalities and replacing the dependent variable. Industrial structure upgrading is vital for green technology innovation to diminish carbon emissions. There is significant regional heterogeneity in the effects of green technology innovation on carbon emissions, i.e., the direct and indirect impact of green technology innovation on carbon emission reduction is significant in the eastern-central area, but its effect is insignificant in the western region. Therefore, it is essential to realize carbon emission reduction by further bolstering green technology innovation and accelerating industrial structure upgrading to fulfill the synergy of technology and structure.

In this article, we examine the empirical association between firm value and CSR engagement for firms in sinful industries, such as tobacco, gambling, and alcohol, as well as industries involved with emerging environmental, social, or ethical issues, i.e., weapon, oil, cement, and biotech. We develop and test three hypotheses, the window-dressing hypothesis, the value-enhancement hypothesis, and the value-irrelevance hypothesis. Using an extesive US sample from 1995 to 2009, we find that CSR engagement of firms in controversial industries positively affects firm (...) value after controlling for various firm characteristics. To address the potential endogeneity problem, we further estimate a system of equations and change regression and continue to find a positive relation between CSR engagement and firm value. Our findings support the value-enhancement hypothesis and are consistent with the premise that the top management of US firms in controversial industries, in general, considers social responsibility important even though their products are harmful to human being, society, or environment.

We empirically examine the impact of corporate social responsibility (CSR) on CEO compensation using a large sample of the US firms from 1996 to 2010. We develop and test two hypotheses, the overinvestment hypothesis based on agency theory and the conflict–resolution hypothesis based on stakeholder theory. We find that the lag of CSR adversely affects both total compensation and cash compensation, after controlling for various firm and board characteristics. Our estimates show that an interquartile increase in CSR is followed by (...) a 4.35% (2.78%) decrease in total (cash) compensation. We also find an inverse association between lagged employee relations and CEO compensation. Our results are robust to the correction for endogeneity using instrumental variable approach. Taken together, our results support the conflict–resolution hypothesis, but not the CSR overinvestment argument. (shrink)

Responsible risk management is central to banking ethics. With the 1999 publication of the Basel Committee's proposal, Basel II, for a New Capital Accord to replace the 1988 agreement, Basel I, an attempt has been made to address the problem of correlating banks' risk management with their capital requirements. The Basel II framework, finalised in June 2004, is designed to improve risk management by using models based on past performance to help set the amount of capital banks are required to (...) hold by regulators, with the purpose of improving the efficiency of capital allocation. The objectives of this study are to investigate how banks generally, but particularly those located in China, could improve their risk management systems and what the implications of these new regulations are for them. Three relevant propositions were formulated, namely, Basel II will improve risk management; Basel II will improve capital allocation efficiency; and compliance with advanced risk management systems is biased in favour of the large banks. Evidence was assembled with which to evaluate these three propositions by gathering relevant primary data by means of a representative survey of Chinese banking executives involved in risk management. The findings strongly support the first two of the above propositions and partly support the third proposition. (shrink)

Despite increasing interest being given to dysfunctional customer behavior in multiple service sectors, it is unclear how and why different types of dysfunctional customer behavior affect frontline employees’ emotional labor during the service interactions. Drawing upon the conservation of resources theory, we propose a conceptual model in which verbal abuse, disproportionate demand, and illegitimate complaint differentially influence frontline employees’ emotional labor strategies. Further, the boundary conditions of these relationships are considered by introducing perceived organizational support and customer orientation as moderators. (...) Using survey data from 436 frontline employees of five call centers in China, hypotheses were tested through a hierarchical regression analysis. The results indicated that verbal abuse and illegitimate complaint exerted positive effects on surface acting. Particularly, these positive effects were weaker when frontline employees perceived organizational support was high. Also, verbal abuse’s positive effect on surface acting was weaker when frontline employees’ customer orientation was high. Customer’s verbal abuse, disproportionate demand, and illegitimate complaint negatively influenced frontline employees’ deep acting. The negative effect of disproportionate demand on deep acting was weaker when perceived organizational support was high. However, when frontline employees’ customer orientation was high, the negative effects of disproportionate demand and illegitimate complaints on deep acting were weaker. (shrink)

The understanding of food cue associated neural activations that predict future weight variability may guide the design of effective prevention programs and treatments for overeating and obesity. The current study investigated the association between brain response to different food odors with varied energy density and individual changes of body mass index (BMI) over two years. Twenty-five participants received high-fat (chocolate and peanut), low-fat (bread and peach) food odors and a nonfood odor (rose) while the brain activation was measured using functional (...) magnetic resonance imaging (fMRI). BMIs were calculated with participant’s self-reported body weight and height collected at the time of fMRI scan and again at two years later. Regression analyses revealed significant negative correlations between BMI increase over 2 years and brain activation of the bilateral precuneus and the right posterior cingulate cortex in response to high-fat versus low-fat food odors. In addition, brain activation of the right supplementary motor area in response to food vs non-food odor was negatively correlated to subsequent BMI increase over 2 years. Taken together, the current findings suggest that individual differences in neural responsivity to (high calorie) food odors in brain regions of the default mode and motor control network serve as a neural marker for future BMI change.

In this study, we examine the relation between corporate environmental responsibility and risk in U.S. public firms. We develop and test the risk-reduction, resource-constraint, and cross-industry variation hypotheses. Using an extensive U.S. sample during the 1991–2012 period, we find that for U.S. industries as a whole, CER engagement inversely affects firm risk after controlling for various firm characteristics. The result remains robust when we use firm fixed effect or an alternative measure of CER using principal component analysis or downside risk (...) measures. To address the concern of endogeneity bias, we use a system equations approach and dynamic system generalized methods of moment regressions, and continue to find that environmentally responsible firms experience lower risk. These findings support the risk-reduction hypothesis, but not the resource-constraint hypothesis, along with the notion that the top management in U.S. firms is generally risk averse and that their CER engagement facilitates their risk management efforts. Our cross-industry analysis further reveals that the inverse CER-risk association mainly comes from the manufacturing sector, whereas in the service sector, CER tends to increase firm risk. (shrink)

This study aims to identify the influence of knowledge management practices on the entrepreneurial and organizational performance with the mediating effect of dynamic capabilities and moderating role of opportunity recognition. Data were gathered from 486 entrepreneurs and applied a structural equation model to test the hypotheses. We found that knowledge management practices have a positive and significant influence on dynamic capabilities, as well as have a significant impact on entrepreneurial and organizational performance. Moreover, results indicated that dynamic capabilities partially mediate (...) in the relationship between knowledge management practices on entrepreneurial and organizational performance. Furthermore, the relationship between knowledge management practices with entrepreneurial and organizational performance strengthening by opportunity recognition.

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual‐character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual‐character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of (...) cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual‐character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual‐character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual‐character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual‐character‐like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow‐up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored. (shrink)

This study investigated the role of entrepreneurial passion in recognition of opportunity, developing entrepreneurial self-efficacy, and entrepreneurial intention, in the shaping of entrepreneurial actions in the presence of proactive personality. This study applied partial least squares structural equation modeling to test the hypotheses on a sample of 346 university students from Jiangsu province, China. The output of the study showed that entrepreneurial passion positively and significantly influenced entrepreneurial alertness, entrepreneurial self-efficacy to entrepreneurial intention, and entrepreneurial behavior. The findings also showed (...) that a proactive personality positively and significantly moderated the relationship between entrepreneurial intention and entrepreneurial behavior. (shrink)

Previous studies argue that religious firms are more ethical and thus engage less in accrual earnings management. At odds with the ethical view, we use a sample of Chinese listed firms and show that firms in religious regions use more real earnings management. We postulate that besides ethics, religion also proxies for risk aversion, which motivates firms to substitute accrual earnings management with real earnings management. Consistent with this view, we show that the positive association between religiosity and real earnings (...) management is more pronounced for firms with lower litigation risk and for firms with less reputable auditors. In addition, we use a mediation model introduced by Baron and Kenny :1173–1182, 1986) to show that religiosity affects earnings management through the channel of risk aversion. We conclude that firms choose real earnings management over accrual-based earnings management because of risk aversion, rather than ethical reasons. (shrink)

This essay examines the cultural politics of Artificial Intelligence (AI) in China through the lens of postsocialism, proposing the concept of a ‘postsocialist AI’ that goes beyond the dominant paradigm of neoliberal informationalism. The essay first explores the distinct state-capital nexus in China’s AI development, characterized by paradoxical modes of operation driven by neoliberal motivations, yet also deeply influenced by symbolic lexicons, value systems, and institutional structures rooted in Leninist-Maoist traditions. The complex interplay of state support, local governmental practices, and (...) market investment showcases ongoing negotiations among contradictory political-economic objectives and subject positions that resist simplification into a globally universalized model of neoliberal capitalism. Further, the essay investigates the ontogenesis or sociogenesis of machine learning – the process through which intelligent machines become socialized through interactions with their sociocultural and political contexts. By foregrounding the interactive encounter between distinct modes of machinic intelligence and Chinese modernity experiences, the essay contests the prevailing neoliberal subjectivity in AI studies and seeks to expand the political horizon limited by the hegemonic figure of homo economicus.

Anticipation is a crucial perceptual-cognitive skill in fast-ball sports, and the effect of high anxiety on performance has attracted more attention from sports psychologists. Related studies mainly focus on the effect of anxiety on influencing processing efficiency and attentional control during information processing in sport. Attentional Control Theory has been supported by several studies. However, these studies have been criticized by the low ecological validity of task design, such as neglecting the dynamic process of anticipation, and inadequate performance analysis, such (...) as analyzing response accuracy and time separately. Using temporal occlusion paradigm, we tested ACT in a dynamic anticipation process. Eighteen skilled and eighteen less-skilled table tennis players were required to anticipate the serves of opponents under dynamic task constraints and anxiety conditions. High cognitive state anxiety decreased processing efficiency for both groups whereas performance effectiveness did not differ. In addition, it negatively affected processing efficiency in early anticipation compared with late anticipation tasks, suggesting that high cognitive state anxiety may have a greater impact on top-down attentional control. Our findings provide support for ACT and show that anxiety impairs anticipation efficiency and performance, possibly due to an ineffectively attentional shift from external kinematic cues to internal long-term working memory. Findings also have implications for the adaptation of attentional strategies and anxiolytic training. (shrink)

This paper proposes a minimal logic of fine-grained information dynamics via belief bases. The framework is shown to be able to accommodate explicit belief, implicit belief, awareness of and awareness that, where awareness of agents is not treated as a tacit premise. A sound and complete axiomatization of static logic is established, upon which a series of dynamic operations are defined. It is argued that these dynamics adapt different scenarios. Our logic is minimal because to each agent we only attach (...) two databases, from which a variety of epistemic attitudes are generated. (shrink)

This paper uses an innovative way to screen stocks and analyzes the relationship between corporate environmental responsibility and long-run stock returns. By our definition, an environmentally responsible (green) company gives no environmental concern and shows environmental strength(s). Using 20 years’ data of 1992–2011, we find evidence that environmentally responsible company outperforms, in the 4th to 7th year after the screening year. An equal-weighted environmentally responsible portfolio earned an annual four-factor alpha of 4.06 % in the 4th year, 3.00 % above (...) industry benchmarks, and 3.87 % above characteristic benchmarks. The results are robust to alternative portfolio weighting methodologies, controlling for firm characteristics, and the removal of outliers. Testing using industry-adjusted Tobin’s Q, we find consistent evidence that environmental strength creates firm value. We argue that environmental responsibility is an intangible asset, likely to be undervalued by the market, especially in the long horizon, thereby causing environmentally responsible companies to exhibit long-horizon excess returns.

We propose that local corruption distorts the allocation of government-controlled resources and impairs the contract environment, thereby reducing firms’ use or suppliers’ provision of trade credit. We use a sample of Chinese-listed firms from 2007 to 2020 to examine the role of local corruption in firms’ access to trade credit and find that the level of local corruption is negatively related to firms’ trade credit use. This effect is more pronounced in firms with weak (vs. strong) internal governance, slack (tight) (...) external monitoring and high (low) supplier concentration. The results of path analysis show that local corruption extends short-term bank loans as well as government subsidies and impairs firms’ accounting quality, thereby inhibiting firms’ demand for or suppliers’ provision of trade credit. Moreover, the post-2012 anti-corruption campaign in China plays a significant role in correcting the misallocation of trade credit caused by corruption. The results of this study illuminate the negative external effects of local corruption on trade credit. (shrink)
