Makalede; Eröz’ün (...) tespitleri ile araştırmacının tespitleri karşılaştırmalı bir şekilde ele alınmıştır. Böylelikle iki çalışma arasındaki uzun süre zarfı göz önüne alınarak, Siverek Karakeçililerinin yaşadığı değişim ve dönüşüm değerlendirilmiştir. Çalışma bu yönüyle özgünlük arz etmektedir. (shrink)

From the perspective of the integrative model of organizational trust, this study proposes a multi-level model for whether, how, and when differentiated empowering leadership influences followers’ trust in leaders and their work outcomes. Drawing on a sample of 372 followers from 97 teams in China, it was found that the negative effect of differentiated empowering leadership on followers’ trust in leaders became salient when followers’ Chinese traditionality was low. Moreover, followers’ trust in leaders mediated the effect of differentiated empowering leadership (...) and Chinese traditionality on followers’ in-role performance, extra-role performance, and counterproductive work behaviors toward the organization. These findings have implications for managerial theory and practice in the domains of trust and differentiated empowering leadership. (shrink)

Before World War II, Taiwan became the second-largest coca leaf production base in Asia, second only to Java, contributing to Japan's position as the world's largest exporter of cocaine. While Japan's opium empire has been the subject of extensive academic inquiry, its coca empire has received far less attention. This article explores Taiwan's role in Japan's dual empire of opium and coca, focusing on the environmental and historical factors that enabled the island to rapidly expand coca production. It finds that, (...) in addition to Taiwan's favorable climate for coca cultivation, the island's long-established tea industry provided mature techniques for harvesting and drying the coca leaves. Furthermore, the sugar company supplied the necessary equipment and capital for the extraction of cocaine, becoming a key resource in the industry's development. Learning from the limitations of the opium monopoly—where raw materials were increasingly constrained by international markets—the colonial government sought to promote self-sufficiency in coca production. This strategy not only ensured a stable supply of raw materials but also allowed the coca industry to balance for the declining incomes from opium as international controls tightened. From all angles, the coca industry met Japan's expectations as a “promising drug.”. (shrink)

People can discriminate the synchrony between audio-visual scenes. However, the sensitivity of audio-visual synchrony perception can be affected by many factors. Using a simultaneity judgment task, the present study investigated whether the synchrony perception of complex audio-visual stimuli was affected by audio-visual causality and stimulus reliability. In Experiment 1, the results showed that audio-visual causality could increase one's sensitivity to audio-visual onset asynchrony (AVOA) of both action stimuli and speech stimuli. Moreover, participants were more tolerant of AVOA of speech stimuli (...) than that of action stimuli in the high causality condition, whereas no significant difference between these two kinds of stimuli was found in the low causality condition. In Experiment 2, the speech stimuli were manipulated with either high or low stimulus reliability. The results revealed a significant interaction between audio-visual causality and stimulus reliability. Under the low causality condition, the percentage of “synchronous” responses of audio-visual intact stimuli was significantly higher than that of visual_intact/auditory_blurred stimuli and audio-visual blurred stimuli. In contrast, no significant difference among all levels of stimulus reliability was observed under the high causality condition. Our study supported the synergistic effect of top-down processing and bottom-up processing in audio-visual synchrony perception. (shrink)

Integrating affective events theory, work-family compensation, and moral balance theory, the present study proposes a model that examines how and when abusive supervisory behavior is related to employees’ deviant behavior toward their supervisor. Using a diary method that involved two surveys per day over two weeks, we found support for our model based on 707 daily observations from 130 employees. Specifically, anger toward one’s supervisor mediated the relationship between abusive supervisory behavior and deviant behavior toward one’s supervisor. In addition, the (...) degree to which employees engaged in deviant behavior toward their supervisor depended on their prior-day deviant behavior toward their family. When employees engaged in lower prior-day deviant behavior toward their family, anger toward their supervisor was positively related to subsequent deviant behavior toward their supervisor. In contrast, when employees had higher prior-day deviant behavior toward their family, the relationship between anger toward their supervisor and deviant behavior toward their supervisor was weaker. We conclude by discussing the implications of our findings for research on abusive supervision, work-family interface, and moral balance theory. (shrink)

This work explored the mediating effects of affective commitment on transformational leadership and job performance and job insecurity on transformational leadership and affective commitment. Meanwhile, the inter-relationships between the four verified the mediating effect of affective commitment, including job insecurity. The results were as follows: transformational leadership and job performance were positively related. Transformational leadership was proportional to an emotional commitment. The affective commitment had a positive impact on job performance. Transformational leadership indirectly positively affected job performance through the intermediary (...) effect of affective commitment. Transformational leadership regulated affective commitment through job insecurity. The more job security employees have, the higher the impact of transformational leadership on affective commitment; the lower the contrary. (shrink)

Numerous studies have shed some light on the importance of associated factors of collaborative attitudes. However, most previous studies aimed to explore the influence of these factors in isolation. With the strategy of data-driven decision making, the current study applied two data mining methods to elucidate the most significant factors of students' attitudes toward collaboration and group students to draw a concise model, which is beneficial for educators to focus on key factors and make effective interventions at a lower cost. (...) Structural equation model trees and structural equation model forests were applied to the Program for International Student Assessment 2015 dataset. By establishing the most important predictors and the splitting rules, these methods constructed multigroup common factor models of collaborative attitudes. The SEM trees showed that home educational resources, home possessions, mother's education, and gender were the most important predictors among the demographic variables, drawing a 5-group model. Among all the predictors, achievement motivation and sense of belonging at school were the most important, drawing a 6-group model. The SEM forest findings proved the relative importance of these variables. This paper discusses various interpretations of these results and their implications for educators to formulate corresponding interventions. Methodologically, this research provides a data mining approach to discover important information from large-scale educational data, which might be a complementary approach to enhance data-driven decision making in education.

Student–teacher relationships have been examined by many studies. However, an omission still exists, the existing scales are not appropriate for studying STRs in private colleges because of the special character of these schools. This paper presents the development and validation of Private-College Student–Teacher Relationship Scale, the first instrument to evaluate student–teacher relationships in private colleges. The PCSTRS has six dimensions: trust, interaction, intimacy, care, approval, and comfort. In our main study, the validity and reliability of the six-factor PCSTRS model were (...) demonstrated. The result of internal consistency coefficient indicated the high reliability of the scale, and the result of concurrent validity indicated the significant correlational relationships between the PCSTRS with other STR measures. In supplementary study, the PCSTRS was administered to 360 participants to confirm the applicability of PCSTRS and investigate the relation of STRs and students’ traits, performance, and wellbeing, as well as the differences between the private school and the public school in this relation; the analyses revealed that there were significant differences in trust, intimacy, and care between private and public colleges; positive correlations were found between STRs and self-esteem, self-efficacy, academic performance, extracurricular activity involvement, and subjective wellbeing. Present research firstly develops the PCSTRS, examined the reliability and validity, and provides the proposed nomological network among related constructs. (shrink)

The complexity of calcium profiles observed in plant cells has led to the realization that specific patterns of calcium propagation (now termed calcium signatures) encode specific information and relay it to downstream elements (effectors) for translation into corresponding cellular responses in higher plants. The concept of calcium signatures is now well established and the tight control of the temporal and spatial characteristics of cytosolic calcium alterations is considered to be responsible for the specificity of various cellular responses, in particular to (...) environment‐induced stresses. To date, three major classes of plant calcium sensors responsible for drought‐stress signal transduction during soil water deficit have been identified. Valuable pieces of the calcium signal‐specificity puzzle are being put together and are illustrated here for the calcium‐mediated signal‐transduction cascades that operate in the responses of higher plants to soil environmental deficits.

With the change in the location of school education from the classroom to the home during the COVID-19 outbreak, there should be more educational caregiving from children’s parents when children learn online. Parental involvement in children’s online learning including study guide and psychological counseling is the specific content of educational caregiving, which is different from face-to-face learning. More attention should be paid to parental involvement and parents’ satisfaction with the online learning effect. This study therefore conducted a survey on middle (...) school students’ parents to establish a moderating model, exploring the influence of parental involvement on parent satisfaction, and the number of children and parental education level as the moderator variables influencing parental involvement. The results show that there is a significant positive correlation between parental involvement and satisfaction, while the parental education level and the number of children both have a moderating effect on the relationship between parental involvement and parent satisfaction. The moderating effect of the education level of parents shows negative, while the moderating effect of the number of children is positive. An interesting finding is that the number of children has a very low influence on parental involvement. (shrink)

In the paper we construct a new kind of fractional dynamical model, i.e. the fractional relativistic Yamaleev oscillator model, and explore its dynamical behaviors. We will find that the fractional relativistic Yamaleev oscillator model possesses Lie algebraic structure and satisfies generalized Poisson conservation law. We will also give the Poisson conserved quantities of the model. Further, the relation between conserved quantities and integral invariants of the model is studied and it is proved that, by using the Poisson conserved quantities, we (...) can construct integral invariants of the model. Finally, the stability of the manifold of equilibrium states of the fractional relativistic Yamaleev oscillator model is studied. The paper provides a general method, i.e. fractional generalized Hamiltonian method, for constructing a family of fractional dynamical models of an actual dynamical system. (shrink)

The online healthcare community has attained rapid development in recent years in which users are facilitated to exchange disease information and seek medical treatment. However, users’ motivation of participation in OHCs is still under investigation. Taking the perspective of user perceived value, this paper examined the impacts of different incentive levels including identity incentive, privilege incentive, and material incentive on user perceived value, user engagement, and user loyalty. To test the proposed hypotheses, the study adopted the methods of the between-subjects (...) experiment and questionnaire. Based on the data analysis by ANOVA and structural equation model, the results show there are significant differences in the impacts of different incentive levels on users’ perceived value. Most of the incentive measures exert significant effects on simple user hedonic value and community identity value. Accordingly, the research findings suggest that affective support value and self-health management value demonstrate more importance for user engagement and user loyalty. Therefore, OHCs should try to improve users’ affective support value and self-health management value which are the ultimate aims of the OHCs. Our study sheds some light on profoundly understanding the design of incentive mechanism of OHC and contributes to the research of OHC services. (shrink)

Alcohol use disorder is one of the most common substance use disorders contributing to both behavioral and cognitive impairments in patients with AUD. Recent neuroimaging studies point out that AUD is a typical disorder featured by altered functional connectivity. However, the details about how voxel-wise functional coordination remain unknown. Here, we adopted a newly proposed method named functional connectivity density to depict altered voxel-wise functional coordination in AUD. The novel functional imaging technique, FCD, provides a comprehensive analytical method for brain's (...) “scale-free” networks. We applied resting-state functional MRI toward subjects to obtain their FCD, including global FCD, local FCD, and long-range FCD. Sixty-one patients with AUD and 29 healthy controls were recruited, and patients with AUD were further divided into alcohol-related cognitive impairment group and non-cognitive impairment group. All subjects were asked to stay stationary during the scan in order to calculate the resting-state gFCD, lFCD, and lrFCD values, and further investigate the abnormal connectivity alterations among AUD-NCI, ARCI, and HC. Compared to HC, both AUD groups exhibited significantly altered gFCD in the left inferior occipital lobe, left calcarine, altered lFCD in right lingual, and altered lrFCD in ventromedial frontal gyrus. It is notable that gFCD of the ARCI group was found to be significantly deviated from AUD-NCI and HC in left medial frontal gyrus, which changes probably contributed by the impairment in cognition. In addition, no significant differences in gFCD were found between ARCI and HC in left parahippocampal, while ARCI and HC were profoundly deviated from AUD-NCI, possibly reflecting a compensation of cognition impairment. Further analysis showed that within patients with AUD, gFCD values in left medial frontal gyrus are negatively correlated with MMSE scores, while lFCD values in left inferior occipital lobe are positively related to ADS scores. In conclusion, patients with AUD exhibited significantly altered functional connectivity patterns mainly in several left hemisphere brain regions, while patients with AUD with or without cognitive impairment also demonstrated intergroup FCD differences which correlated with symptom severity, and patients with AUD cognitive impairment would suffer less severe alcohol dependence. This difference in symptom severity probably served as a compensation for cognitive impairment, suggesting a difference in pathological pathways. These findings assisted future AUD studies by providing insight into possible pathological mechanisms. (shrink)

Emerging medical biotechnology typically exhibits a ‘dual-use’ nature, which, while promoting human well-being, concurrently presents potential risks of misuse or abuse, thereby posing significant threats. Globally, including in China, emerging medical biotechnology is developing rapidly. To understand the views and perspectives of Chinese scientists on dual-use concerns, this empirical study conducted semistructured qualitative interviews with researchers (n=14) from various specialties within the Chinese medical field, analysing their perspectives and ethical considerations regarding dual-use concerns. The findings of this study reveal a (...) spectrum of attitudes among interviewees towards the exploration and application of emerging medical biotechnology, ranging from aggressive to conservative. This tension reflects the complexity and challenges of seeking a balance between promoting scientific innovation and maintaining ethical boundaries. Furthermore, while there is a consensus among scientists that the development and application of biotechnology encompass both risks and benefits, their stances on weighing these factors differ, reflecting how risk perception is influenced by professional limitations. Moreover, although scientists recognise the indispensability of both self-regulation and external oversight in practice, they also exhibit misunderstandings in ethical cognition and misinterpretations of regulatory measures. In light of these findings, it is imperative for us to urgently fortify national regulatory mechanisms and the construction of legal and ethical frameworks while also enhancing the ethical awareness and risk assessment capabilities of researchers. These measures are crucial for minimising the potential risks associated with dual use and fostering the sustainable and responsible development of emerging medical biotechnology. (shrink)
