Mental health is an important basic condition for college students to become adults. Educators gradually attach importance to strengthening the mental health education of college students. This paper makes a detailed analysis and research on college students’ mental health, expounds the development and application of clustering analysis algorithm, applies the distance formula and clustering criterion function commonly used in clustering analysis, and makes a specific description of some classic algorithms of clustering analysis. Based on expounding the advantages and disadvantages of (...) fast-clustering analysis algorithm and hierarchical clustering analysis algorithm, this paper introduces the concept of the two-step clustering algorithm, discusses the algorithm flow of clustering model in detail, and gives the algorithm flow chart. The main work of this paper is to analyze the clustering algorithm of students’ mental health database formed by mental health assessment tool test, establish a data mining model, mine the database, analyze the state characteristics of different college students’ mental health, and provide corresponding solutions. In order to meet the needs of the psychological management system based on the clustering analysis method, the clustering analysis algorithm is used to cluster the data. Based on the original database, this paper establishes the methods of selecting, cleaning, and transforming the data of students’ psychological archives. Finally, it expounds on the application of data mining in students’ psychological management system and summarizes and prospects the implementation of the system. (shrink)

In this essay I review four recent monographs on Chinese American history: Xiao-huang Yin's Chinese American Literature since the 1850s, Madeline Hsu's Dreaming of Gold, Dream of Home: Transnationalism and Migration Between the United States and South China, Young Chen's Chinese San Francisco 1850-1943: A Trans-Pacific Community, and Xiaojian Zhao's Remaking Chinese America: Immigration, Family, and Community, 1940-1965. Based on both English- and Chinese-language sources, the authors of these four books explore migration processes and the social origins of Chinese (...) immigrants from an international perspective and they reinterpret the cultural values of immigrants as fundamentally open, engaged, and cosmopolitan. Moreover, they characterize the Chinese American community as a dynamic, fluid, and flexible global network and place Chinese America in a larger historical context beyond that of a single nation. They have seriously challenged the American-centered and nation-based research paradigm and promoted a more transnational, transcultural, and multilingual approach to the history of Asian American experience.

Calibration errors are inevitable and should not be ignored during the estimation of item parameters. Items with calibration error can affect the measurement results of tests. One of the purposes of the current study is to investigate the impacts of the calibration errors during the estimation of item parameters on the measurement accuracy, average test length, and test efficiency for variable-length cognitive diagnostic computerized adaptive testing. The other purpose is to examine the methods for reducing the adverse effects of calibration (...) errors. Simulation results show that calibration error has negative effect on the measurement accuracy for the deterministic input, noisy “and” gate model, and the reduced reparameterized unified model; the average test lengths is shorter, and the test efficiency is overestimated for items with calibration errors; the compensatory reparameterized unified model is less affected by the calibration errors, and the classification accuracy, average test length, and test efficiency are slightly stable in the CRUM framework; methods such as improving the quality of items, using large calibration sample to calibrate the parameters of items, as well as using cross-validation method can reduce the adverse effects of calibration errors on CD-CAT.

Media guidelines on safe suicide-related reporting are within the suicide prevention armamentarium. However, implementation issues beleaguer real-world practice. This study evaluated the perspectives of the Malaysian media community, persons with lived experience of suicidal behavior, and mental health professionals on suicide-related reporting in terms of the impact, strategies, challenges, and the implementation of guidelines on safe reporting. Three focus group discussions of purposively sampled Malaysian media practitioners, PLE, and MHP were audio-recorded, transcribed, coded and thematically analyzed. Inclusion criteria were: English (...) fluency, no clinical depression or suicidal ideation, no recent previous suicide attempts or suicide bereavement. Three major themes emerged: Unsafe Reporting; Impact; and Safe Reporting. Most described current reporting as unsafe by being potentially triggering to media users and may contribute to contagion effect. Positive impacts identified included raised awareness toward suicide and its prevention. Unsafe reporting was attributed to inadequate awareness, knowledge, and guidance, lack of empathy and accountability, job-related factors, popularity-seeking, lack of monitoring and governance, and information source with unsafe content. Majority agreed on how suicide stories should be framed to produce a safe report. The media community diverged on how detailed a suicide story should be. Safe reporting challenges included difficulties in balancing beneficial versus harmful details, social media ubiquity and its citizen reporters. Participants suggested these safe reporting strategies: stakeholder engagement, educational approaches, improving governance and surveillance, and guidelines revision. Most acknowledged the relevance of guidelines but were unaware of the existence of local guidelines. Implementation challenges included the dilemma in balancing media industry needs vis-à-vis safe reporting requirements, stakeholder engagement difficulties and social media regulation. There is poor awareness regarding safe suicide-related reporting across all groups. PLE and MHP were negatively impacted by current unsafe messaging which aggravated trauma and grief reactions. Postvention support gaps for mental health professionals were highlighted. Safe reporting promotion strategies should include stakeholder engagement to increase awareness on minimizing Werther and maximizing Papageno effects. Strategic re-examination and dissemination of local media guidelines to address new media issues, and effective surveillance mechanisms, are crucial in sustainable improvement of safe reporting practices.

There have been many discussions on problems of logic over the past several years. While the problem of the nature of the law of contradiction, one of the laws of formal logic, has received particular attention by everyone, the question has not been posed very precisely in the arguments. Actually, the question is not whether the movement, change, and development of things can be reflected in consciousness by use of the methods of formal logic, or in distinguishing the effectiveness of (...) the law of contradiction in disputation, proofs, or theoretical systems from its effectiveness in the general process of cognition, when applied to phenomena. If the development of reality cannot at all be reflected by the use of the logical tools of formal logic, what use do they have? No one denies that formal logic does not suffice as a method of cognition. If, in disputations and proofs, or in the establishment of theoretical systems, one relies only on the logical tools of formal logic, this is also not enough. The scope of applicability of the laws of formal logic, as laws that are studied by a concrete science, is necessarily limited. It is impossible for them to be all-powerful; it is of course impossible, relying on the law of contradiction, to know and grasp the contradictions in reality — the unity and conflict of opposites. All disputations and proofs, and the establishment of theoretical systems, are, in fact, efforts to know real objects, efforts of the subjective to grasp the objective. In principle, the use of formal logic in disputations and proofs and in the establishment of theoretical systems, and its use in knowing an object, should be no different. What, then, is the question? The question should be posed as follows: can thought contravene the law of contradiction? (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)

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.

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)

Receptor‐mediated stimulation induces massive actin polymerization and cyto‐skeletal reorganization. The activity of a potent actin‐modulating protein, gelsolin, is regulated both by Ca2+ and polyphos‐phoinositides, and it may have a pivotal role in restructuring the actin cytoskeleton in response to agonist stimulation. Structure‐function analysis of gelsolin has (1) indicated that its NH2‐terminal half is primarily responsible for modulating actin filament length and polymerization; and (2) elucidated mechanisms by which Ca2+ and phospholipids may regulate such functions. Gelsolin is functionally and structurally similar (...) to villin, another Ca2+‐activated actin‐severing protein found in microvilli, suggesting that gelsolin may be a prototype of this family of actin‐modulating proteins. A molecular variant of gelsolin is secreted and may be involved in the clearance of actin filaments released during tissue damage. The two forms of gelsolin are encoded by a single gene, and distinct messages are derived by alternative message splicing. (shrink)

We find that agency problems are embedded in firm's excess and abnormal equity investments that are mainly dictated by controlling shareholder's motives and ethical choices manifested in ownership and board structure. The excess equity investment is gauged with respect to industry average. The abnormal equity investment is specifically referred to the number of nominal investment companies that are fully controlled by the controlling owners while subject to little governance. Our empirical evidences of 345 Taiwanese non-financial listed firms show that firm's (...) excess and abnormal equity investments are negatively correlated with controlling shareholder's cash flow rights while are positively correlated with the control-cash flow deviation, and board affiliation. The results are supportive of the positive incentive hypothesis and the negative entrenchment hypothesis put forth by La Porta et al. (2002, Journal of Finance 57, 1147-1171) and Claessen et al. (2002, Journal of Finance 57, 2741-2742). The negative relation between equity investment and firm's value further supports the agency postulation that corporate excess and abnormal equity investments represent a leeway for controlling shareholder to exploit wealth of minority shareholders. This study potentially contributes to the literature of business ethics by portraying an empirically testable linkage from controlling owner's ethical choices to his actions and therefore firm's value.

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)

Through statistical analysis of datasets describing single cell shape following systematic gene depletion, we have found that the morphological landscapes explored by cells are composed of a small number of attractor states. We propose that the topology of these landscapes is in large part determined by cell‐intrinsic factors, such as biophysical constraints on cytoskeletal organization, and reflects different stable signaling and/or transcriptional states. Cell‐extrinsic factors act to determine how cells explore these landscapes, and the topology of the landscapes themselves. Informational (...) stimuli primarily drive transitions between stable states by engaging signaling networks, while mechanical stimuli tune, or even radically alter, the topology of these landscapes. As environments fluctuate, the topology of morphological landscapes explored by cells dynamically adapts to these fluctuations. Finally we hypothesize how complex cellular and tissue morphologies can be generated from a limited number of simple cell shapes. (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.

In a series of pre-registered studies, we explored (a) the difference between people’s intuitions about indeterministic scenarios and their intuitions about deterministic scenarios, (b) the difference between people’s intuitions about indeterministic scenarios and their intuitions about neurodeterministic scenarios (that is, scenarios where the determinism is described at the neurological level), (c) the difference between people’s intuitions about neutral scenarios (e.g., walking a dog in the park) and their intuitions about negatively valenced scenarios (e.g., murdering a stranger), and (d) the difference (...) between people’s intuitions about free will and responsibility in response to first-person scenarios and third-person scenarios. We predicted that once we focused participants’ attention on the two different abilities to do otherwise available to agents in indeterministic and deterministic scenarios, their intuitions would support natural incompatibilism—the view that laypersons judge that free will and moral responsibility are incompatible with determinism. This prediction was borne out by our findings. (shrink)

Self-identity of Individual-subject is evaluative knowledge and factive confirmation on basic of an evaluative knowledge on “who am I”. Crisis of Self-identity of Individual-subject is a extremely stern reality which Individual-subject is confronted with in modern sociality.

We construct Hrushovski–Kazhdan style motivic integration in certain expansions of ACVF. Such an expansion is typically obtained by adding a full section or a cross-section from the RV-sort into the VF-sort and some extra structure in the RV-sort. The construction of integration, that is, the inverse of the lifting map , is rather straightforward. What is a bit surprising is that the kernel of is still generated by one element, exactly as in the case of integration in ACVF. The overall (...) construction is more or less parallel to the main construction of Hrushovski and Kazhdan , as presented in Yin and Yin . As an application, we show uniform rationality of Igusa zeta functions for non-archimedean local fields with unbounded ramification degrees. (shrink)

We present two of the three major steps in the construction of motivic integration, that is, a homomorphism between Grothendieck semigroups that are associated with a first-order theory of algebraically closed valued fields, in the fundamental work of Hrushovski and Kazhdan [8]. We limit our attention to a simple major subclass of V-minimal theories of the form ACV FS, that is, the theory of algebraically closed valued fields of pure characteristic 0 expanded by a -generated substructure S in the language (...) . The main advantage of this subclass is the presence of syntax. It enables us to simplify the arguments with many different technical details while following the major steps of the Hrushovski–Kazhdan theory. (shrink)

This paper discusses the ethical implications of racism and some of the various costs associated with racism occurring at the institutional level. We argue that, in many ways, the laws, social structures, and institutions in Western society have operated to perpetuate the continuation of historical legacies of racial inequities with or without the intention of individuals and groups in society. By merely maintaining existing structures, laws, and social norms, society can impose social, economic, and health costs on racial minorities that (...) impinge on their well-being and human dignity. Based on a review of multidisciplinary research on racism, particularly focusing on healthcare, we demonstrate how institutional racism leads to social and economic inequalities in society. By positing institutional racism as the inherent cause of avoidable disparities in healthcare, this paper draws attention to the ethical significance of racism, which remains a relatively neglected issue in bioethics research.

In 1908, the first and second chapters of Kropotkin’s Mutual Aid were first translated into Chinese by Li Shizeng, greatly influencing Chinese anarchists. Li Shizeng followed Kropotkin’s scientific argument of anarchism and strengthened the viewpoint for praising “public” and suppressing “private”. When translating Kropotkin’s thoughts, Li Shizeng focused on political revolution, glossing over the criticism of the capitalist economy, and barely referenced Kropotkin’s original anarchist communist ideology.

We prove that if an equicharacteristic valued field has a ℤ-group as its value group and admits quantifier elimination in the main sort of the prototypical Denef-Pas style language then it is henselian. In fact the proof of this suggests that a reasonable class of Denef-Pas style languages is natural with respect to henselianity.

Obstetric ultrasound is the well-recognized prenatal test used to visualize and determine the condition of a pregnant woman and her fetus. Apart from the clinical application, some businesses have started promoting the use of fetal ultrasound machines for nonmedical reasons. Non-medical fetal ultrasound (also known as ‘keepsake’ ultrasound) is defined as using ultrasound to view, take a picture, or determine the sex of a fetus without a medical indication. Notwithstanding the guidelines and warnings regarding ultrasound safety issued by governments and (...) professional bodies, the absence of scientifically proven physical harm to fetuses from this procedure seems to provide these businesses with grounds for rapid expansion. However, this argument is too simplistic because current epidemiological evidence is not synchronous with advancing ultrasound technology. As non-medical fetal ultrasound has aroused very significant public attention, a thorough ethical analysis of this topic is essential. Using a multifaceted approach, we analyse the ethical perspective of non-medical fetal ultrasound in terms of the expectant mother, the fetus and health professionals. After applying four major theories of ethics and principles (the precautionary principle; theories of consequentialism and impartiality; duty-based theory; and rights-based theories), we conclude that obstetric ultrasound practice is ethically justifiable only if the indication for its use is based on medical evidence. Non-medical fetal ultrasound can be considered ethically unjustifiable. Nevertheless, the ethical analysis of this issue is time dependent owing to rapid advancements in ultrasound technology and the safety issue. The role of health professionals in ensuring that obstetric ultrasound is an ethically justifiable practice is also discussed. (shrink)

Differences and similarities between modal and amodal completions can only be understood by considering the goals of visual completion: unity, shape, and perceptual quality. Pessoa et al. cannot reject representational accounts of vision because of flaws with isomorphic representations of perceptual quality: representations and processes for perceptual quality (modal completion) and most likely dissociable from those for unity and shape (nonmodal completions).

By summarizing, in a single piece, various current perspectives on addiction, Redish et al. have performed a useful service to the field.

In the course of comparisons and examinations, and after the long-term usage of concepts with similar connotations, the term "modernization" has become universally acknowledged and used in academic circles.

However, in this article I have no intention of discussing modernization itself; rather, I am focusing on the relationships between modernization and nativization and their rule (...) of law.

Zhu Xi’s 朱熹 interpretations systematized the Five Classics; moreover, he elevated the “Four Books” to such a supra-canonical status that these texts along with his commentaries became the core curriculum for civil service examinations from the early 13th century to the 20th century. Inquiring into what was the essential and unique Song 宋 character of Classical scholarship, we will highlight the canonical Ritual Classics because these texts were crucial for centuries, especially during the Han 漢 through Tang 唐 dynasties. We (...) show how Zhu updated ritual practices by focusing on the Yili 儀禮 as the crucial Classic for guidelines on etiquette, and also rebalanced the relation between rituals and moral “principles.” We will explore how Zhu’s systematization of moral principles and ritual did not fully resolve tensions from his major 11th-century philosophical predecessors regarding principles and ritual, as well as the Four Books and the Five Classics. Even if Dai Zhen’s 戴震 criticism of Zhu was somewhat misplaced or overstated, tensions within Zhu’s views provide us a basis for understanding Dai’s attacks and ambivalence among Qing 清 and 20th-century scholars toward Zhu Xi’s philosophy.
