Competition for land is increasing as demand for multiple land uses and ecosystem services rises. Land regulation of the principles of landscape ecology is necessary to develop more sustainable approaches to land use planning. The research evaluated the present land patterns and determined best practices for its regulation of Dongwang Township in Quyang County, located in the Taihang Mountain area of Hebei Province, China. The research used the landscape ecology theory to construct an index system for landscape pattern analysis based (...) on the GIS and Fragstats 3.3 software. In this study, we examined the specific reasons that landscape ecology is superior to traditional methods in land consolidation planning and design, which is conducive to the comprehensive development of land ecological benefits. Landscape ecological planning can effectively reduce landscape fragmentation and improve intensive management. The result found that the descending order of the Shannon index was current landscape, landscape ecological planning, and traditional planning. Landscape ecological planning could protect the natural diversity than traditional planning. Landscape ecological planning enables the creation of long corridors, with higher densities and connectivity and lower average corridor widths than traditional planning. Besides, it can improve ecological service function values in the study area to varying degrees, thus discouraging residents from limiting themselves to grain production. This research has great potential to improve the visibility of ecosystem services in local land use planning and, thus, to improve the ecological functioning of future landscapes. (shrink)

ABSTRACTThree experiments examined how people reason about what is possible or necessary when a conditional is true. Participants were asked to indicate whether it was necessary, possible or impossible for a specific instance to conform to one of the truth-table cases, given the truth of the conditional. It was found that most participants, inconsistently, judged the pq case as necessary but the ¬pq or ¬p¬q cases as possible. Logically, these two kinds of judgments are contradictory. Moreover, a true conditional doesn’t (...) imply that a specific instance under the conditional must be pq. Therefore, people demonstrate a necessity illusion for pq cases which contradicts their commitment to the possibility of ¬pq or ¬p¬q cases. Existing accounts of conditionals are unable to explain the contradiction and the necessity illusion. We propose an inference dissociation account and explore the theoretical implications of this necessity illusion. (shrink)

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.

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)

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.

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.

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)

The spatial organization of the genome is intimately linked to its biological function, yet our understanding of higher order genomic structure is coarse, fragmented and incomplete. In the nucleus of eukaryotic cells, interphase chromosomes occupy distinct.

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.

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)

This paper proposes an extended version of the interventionist account for causal inference in the practical context of biological mechanism research. This paper studies the details of biological mechanism researchers’ practices of assessing the evidential legitimacy of experimental data, arguing why quantity and variety are two important criteria for this assessment. Because of the nature of biological mechanism research, the epistemic values of these two criteria result from the independence both between the causation of data generation and the causation in (...) question and between different interventions, not techniques. The former independence ensures that the interventions in the causation in question are not affected by the causation that is responsible for data generation. The latter independence ensures the reliability of the final mechanisms not only in the empirical but also the formal aspects. This paper first explores how the researchers use quantity to check the effectiveness of interventions, where they at the same time determine the validity of the difference-making revealed by the results of interventions. Then, this paper draws a distinction between experimental interventions and experimental techniques, so that the reliability of mechanisms, as supported by the variety of evidence, can be safely ensured in the probabilistic sense. The latter process is where the researchers establish evidence of the mechanisms connecting the events of interest. By using case studies, this paper proposes to use ‘intervention’ as the fruitful connecting point of literature between evidence and mechanisms. (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)

Gender roles are anti-dichotomous and malleable social constructs that should theoretically be constructed independently from biological sex. However, it is unclear whether and how the factor of sex is related to neural mechanisms involved in social constructions of gender roles. Thus, the present study aimed to investigate sex specificity in gender role constructions and the corresponding underlying neural mechanisms. We measured gender role orientation using the Bem Sex-Role Inventory, used a voxel-based global brain connectivity method based on resting-state functional magnetic (...) resonance imaging to characterize the within-network connectivity in the brain reward network, and analyzed how the integration of the reward network is related to gender role scores between sex groups. An omnibus analysis of voxel-wise global brain connectivity values within a two-level linear mixed model revealed that in female participants, femininity scores were positively associated with integration in the posterior orbitofrontal cortex and subcallosal cortex, whereas masculinity scores were positively associated with integration in the frontal pole. By contrast, in male participants, masculinity was negatively correlated with integration in the nucleus accumbens and subcallosal cortex. For the first time, the present study revealed the sex-specific neural mechanisms underlying distinct gender roles, which elucidates the process of gender construction from the perspective of the interaction between reward sensitivity and social reinforcement.

Drawing on the conservation of resource theory, we theorized and tested a serial mediation model linking empowering leadership with employee radical creativity through job control and willingness to take risks. We tested our hypotheses using data collected from a time-lagged and multisource survey of 385 employees in 84 research and development teams from 20 different companies. The results demonstrated that empowering leadership had a positive indirect effect on employee radical creativity via job control and willingness to take risks, and the (...) error management climate was found to strengthen this indirect effect. Theoretical and practical implications are also provided in the discussion section. (shrink)

In this paper, we investigate universal and existential quantifiers on NM-algebras. The resulting class of algebras will be called monadic NM-algebras. First, we show that the variety of monadic NM-algebras is algebraic semantics of the monadic NM-predicate logic. Moreover, we discuss the relationship among monadic NM-algebras, modal NM-algebras and rough approximation spaces. Second, we introduce and investigate monadic filters in monadic NM-algebras. Using them, we prove the subdirect representation theorem of monadic NM-algebras, and characterize simple and subdirectly irreducible monadic NM-algebras. (...) Finally, we present the monadic NM-logic and prove its completeness with respect to monadic NM-algebras. These results constitute a crucial first step for providing an algebraic foundation for the monadic NM-predicate logic. (shrink)

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)

Purpose – This study aims to investigate the perceptions, acceptance, usage and access to social media by students and academics in higher education in informatics programs in Malaysia. A conceptual model based on Connectivism and communities of practice learning theory was developed and were used as a basis of mapping the research questions to the design frameworks and the research outcomes. A significant outcome of this study will be the development of a design framework for implementing social media as supporting (...) tools for student engagement and teaching and learning of informatics programs in higher education institutions in Malaysia. Design/methodology/approach – A mixed-method research methodology with a significant survey research component was employed for this research. This methodology focused on collecting and analyzing quantitative and qualitative data to better understand the research problems. For this study, a mixed-method sequential transformative research strategy based on a QUAN-Qual model was used in the data collection process. Mixed-method research methodology is considered to be most appropriate for this study, as it allows the researcher to gather multiple forms of data from diverse audiences such as educators, administrators and students. Findings – The findings show the close matched of the ownership, amount of hours spent online, types of social media technologies used and pattern of usage between informatics and non-informatics students. It also shows that many students and instructors have started to explore and accept the use of SMTs as a tool for engaging with their institution and their peers as well as for teaching and learning purposes. Innovative institutions need to understand the critical success factors and the barriers that restrict the implementation of SMTs within the HEI to take advantage of the opportunities offered by SMTs in higher education. Research limitations/implications – The surveys and interview participant, in part, are self-selecting, so the data collected cannot be claimed to be representative of the population. However, because of the relatively large number of participants, it can be considered that the findings are indicative. Other limitation includes the depth of data that can be collected using this methodology. Practical implications – There is wide range of social media usage in educational settings now being reported, but many issues are still unexamined. Limited studies have been focusing on the educators’ readiness, acceptance or refusal in integrating social media into their courses, the perceived effectiveness of the tools and student outcomes for their learning. The central outcome of this research will be the development of a design framework that will be used as a guide for Malaysian HEIs and informatics academics to engage students using SMTs in creating effective learning communities for informatics programs. Social implications – The framework will have implication for the social interaction and engagement of students with their institution. Originality/value – Very little work has been reported on student and academic engagement, their perspectives and perceived effectiveness of social media usage in higher education, especially in the Malaysia context. Most of the research focused only on the quantitative research with students from universities in the USA and Australia, with an emphasis mainly on student’s perception and acceptance. There are calls for more research to examine how social media is perceived and accepted by students and academics for teaching and learning, especially in Malaysia. (shrink)

We investigate the cross-correlations of return-volume relationship of the Bitcoin market. In particular, we select eight exchange rates whose trading volume accounts for more than 98% market shares to synthesize Bitcoin indexes. The empirical results based on multifractal detrended cross-correlation analysis reveal that the nonlinear dependencies and power-law cross-correlations in return-volume relationship are found; all cross-correlations are multifractal, and there are antipersistent behaviors of cross-correlation for q=2; the price of small fluctuations is more persistent than that of the volume, while (...) the volume of larger fluctuations is more antipersistent; and the rolling window method shows that the cross-correlations of return-volume are antipersistent in the entire sample period.

This study identifies unique corporate social responsibility (CSR) dimensions and develops a framework to analyze different levels of institutional dynamics in understanding CSR in China. Based on multiple case studies of 16 firms, the article examines the CSR philosophy and approach in China's emerging market. The findings suggest that Chinese CSR understanding is largely grounded in the context of ethical and discretionary actions. This focus is mainly attributed to the dominant role of ethical leadership, governmental dependency, and cultural traditions in (...) Chinese CSR. Moreover, the weakness or the absence of conducive social normative environment and positive peer pressure, and misalignment between CSR and organizational design further contribute to a lack of systemic and institutionalized approach to CSR in China. Our study implies that CSR is still evolving at a preliminary stage in China, and institutional infrastructure and cultural ethics are exerting abiding influence on CSR approach in the emerging economies. The article also suggests the implications for practice and policy making. (shrink)

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.

Background: In China, celebrities, represented by entertainment and sports personalities, are often involved in charitable activities to assist the party-state in solving social problems. Although previous research has addressed the manifestation of prosocial behavior by Chinese celebrities, altruistic engagements have rarely been theorized from the perspective of impression management.Methods: Based on the perspective of impression management, we use the discourse analysis approach to analyze the interview manuscripts of Chinese celebrities in media reports and then summarize the charitable motives and impression (...) management strategies adopted by Chinese celebrities in their self-presentation.Results: Chinese celebrities’ self-presentation of philanthropic motives in the media can be roughly divided into five categories: motivation for empathy-altruism, motivation for social responsibility, motivation to gain prestige, and pursue fame, motivation to reduce negative emotions, and motivation to achieve fulfillment and satisfaction. The philanthropic motives presented in media reports include the impression management processes of celebrities. They adopt a variety of image management strategies to self-present their philanthropic motives, and sometimes several strategies coexist.Conclusion: Our paper helps to expand the existing understanding of the relationship between impression management and philanthropy. The presentation of Chinese celebrities’ philanthropic motivations in the media reflects the uniqueness of China’s political, institutional, and social environment in influencing celebrity philanthropy. As a philanthropic phenomenon with Chinese characteristics, this study could provide some insights into the understanding of celebrities and philanthropy in other cultural contexts. (shrink)

Their central message is that addiction comprises many vulnerabilities rather than a single vulnerability. Such a message may not be new, but it is worth repeating.

ObjectivesTo simulate hemodynamic changes after extraluminal compression in pulsatile tinnitus patients with a prominent transverse-sigmoid sinus junction.MethodsOne patient-specific case was reconstructed based on computed tomography venography images of a PT patient. The compression degree served as a new index in this study. Cases with 10, 20, 30, 40, 50, 60, 70, 80, and 90% of the compression degree of the control subject were constructed. Steady-state computational fluid dynamics were assessed. The wall pressure distribution, wall maximum pressure and flow pattern of (...) the PTSJ were calculated to evaluate hemodynamic differences among all cases.ResultsWith increasing compression, the wall pressure at the compression point and downstream of the PTSJ decreased but increased upstream. When the compression degree exceeded 70%, the upstream pressure increased significantly. Above 50% compression, the blood flow pattern downstream of the sigmoid sinus tended to spiral, especially after 80% compression. Beyond 60% compression, the blood flow pattern under the compression axis became more medial.ConclusionMechanical compression of PTSJ changes wall pressure and blood flow patterns. The degree of compression should be carefully observed to avoid possible complications or reoccurrence. (shrink)
