General intelligence is largely based on two distinguishable mental abilities: crystallized intelligence (gC) and fluid reasoning ability (gF). The target article authors' P-FIT model emphasizes a network of regions throughout the brain as the neural basis for fluid reasoning and/or working memory. However, it provides little significant insight into the neural basis of gC, or how or why gC is more stable than gF across the life span.

Cancer chemotherapy has been the most common cancer treatment. However, it has side effects that kill both tumor cells and immune cells, which can ravage the patient’s immune system. Chemotherapy should be administered depending on the patient’s immunity as well as the level of cancer cells. Thus, we need to design an efficient treatment protocol. In this work, we study a feedback control problem of tumor-immune system to design an optimal chemotherapy strategy. For this, we first propose a mathematical model (...) of tumor-immune interactions and conduct stability analysis of two equilibria. Next, the feedback control is found by solving the Hamilton–Jacobi–Bellman equation. Here, we use an upwind finite-difference method for a numerical approximate solution of the HJB equation. Numerical simulations show that the feedback control can help determine the treatment protocol of chemotherapy for tumor and immune cells depending on the side effects. (shrink)

Simion and Kelp explain the trustworthiness of an AI based on that AI’s disposition to meet its obligations. Roughly speaking, according to Simion and Kelp, an AI is trustworthy regarding its task if and only if that AI is obliged to complete the task and its disposition to complete the task is strong enough. Furthermore, an AI is obliged to complete a task in the case where the task is the AI’s etiological function or design function. This account has a (...) strength in that it can provide a unificatory rationale for the trustworthy-making properties of AIs. According to this account, being explainable, being safe, and being transparent are the trustworthy-making properties of an AI because an AI can fulfill its etiological or design functions in the case where it is explainable, safe, and transparent. This paper shows that though Simion and Kelp’s account has a strength, this account is not satisfactory for two reasons. The first reason is that an AI’s trustworthiness is not determined just by the AI’s disposition to meet obligations, and the second reason is that it is difficult to explain how an AI’s etiological function and design function have to do with that AI’s obligations. To provide a full-fledged account, Simion and Kelp should dismiss these concerns. (shrink)

While investigating the value of achievements, Dunkle claims that lucky achievements are possible. For instance, if a person does great works, then it is possible that the works have the status of achievements, even if luck plays a crucial role in doing the great works. Rather than examining Dunkle’s claim, this paper proceeds discussion under the assumption that lucky achievements are possible. In particular, based on this assumption, this paper suggests a new approach to the nature of achievement named the (...) Comparative Value Approach. According to the comparative value approach, a product can have the status of an achievement if the product is valuable in an achievement-relevant domain, and in that domain the product is valuable more than most other items which either have been achieved or can be achieved by others. This paper shows that the comparative value approach successfully explains the cases of achievements, including the cases of lucky achievements. Besides this reason, this paper provides three more reasons to show that the comparative value approach is a feasible view of achievements. The comparative value approach can accommodate the fact that there are various kinds of achievements; the approach can explain the relation between the nature of achievement and the achievement-value of a product; and the approach can show why in determining the status of a product it matters that for average people achieving a similar kind of product is sufficiently difficult. Based on these four reasons, this paper concludes that the comparative value approach is a plausible understanding of achievements. (shrink)

Some goals have special significance to agents. For instance, an agent could find her life worth living because she is pursuing her current goal, and the agent could also think that her previous life has no value because she did not pursue the current goal. If an agent’s current goal has special importance to the agent, then in terms of prudence the agent’s decision to obtain her current goal could be permissible even in the case where achieving her previous goal (...) brings out larger advantages. A widely endorsed thesis of prudence (i.e. the temporal neutrality thesis) does not successfully explain this phenomenon of goal achievement. Furthermore, the present-aim thesis and the harmony thesis also fail in explaining why an agent has prudential reason to prioritize her current goal. This paper introduces a new thesis of prudence, according to which an agent’s caring is significant in deciding whether the agent’s actions are prudentially permissible. In particular, after introducing this thesis named the care thesis, I argue that the care thesis can explain why an agent has reason to prioritize her current goal if the agent finds her life worth living due to her current goal. It is permissible that an agent obtains her current goal rather than previous goal because achieving her current goal benefits the agent’s cared one (i.e. the self who pursues her current goal).

The redemption thesis assumes that how events in a person’s life are related to one another is important in evaluating the person’s welfare throughout life. In particular, according to this thesis of welfare, the fact that a person’s previous hardships contribute to bringing out the same person’s later successes, and the person would regard the hardships as having been worthwhile in light of the successes makes the person’s life better for the person herself. Recently, Ian D. Dunkle provided four objections (...) to the redemption thesis: the intuition concern, the different redemptions argument, the downplaying hardships argument, and the reconciled irreconcilables argument. This paper examines these four objections. In particular, this paper dismisses all the objections showing that the redemption thesis bases on an appealing idea, does not consider the degree of hardship significant in itself, has plausible reasons to evaluate hardships not as serious as people think, and can successfully reconcile its synchronic and diachronic evaluations.

The transnational agrarian movement La Via Campesina (LVC) seeks to reestablish food sovereignty authority within national borders by removing agriculture from the WTO system. The WTO is a membership organization of participating nation-states that have agreed to abide by the rules of the WTO governance regime. Nominally, at least, changes in these governance rules must be approved by the nation-state members. This paper examines the extent to which South Korean affiliate organizations of LVC, the Korean Peasant League and the Korean (...) Women Peasants Association, have been successful in placing food sovereignty issues on the national agri-food policy agenda in South Korea that challenge the WTO’s neoliberal global governance regime for agriculture. In effect, the success of transnational movements like LVC in challenging global institutions may rest on how well their member affiliates are able to play domestic agri-food politics. (shrink)

We empirically analyze the impact of economic uncertainty due to the COVID-19 pandemic on the trading volume of each sector in the S&P 500 index. Wavelet coherence analysis is carried out using economic policy uncertainty data and the trading volume of each sector in the S&P 500 index from July 2004 to September 2020. Furthermore, we apply multifractal detrended fluctuation analysis to the trading volume series of all sectors. The wavelet coherence analysis shows that the COVID-19 pandemic has substantially influenced (...) trading volume in all sectors. However, the impact of the pandemic is different from that during the global financial crisis in some sectors, such as information technology, consumer discretionary, and communication services. Because of the lockdown taken to suppress COVID-19, increased remote working and remote learning are the main reasons for these results. Additionally, according to the MF-DFA analysis, the trading volume of all the sectors has clear multifractal characteristics, and they are all nonpersistent. Specifically, trading volumes of the real estate and materials sector are highly correlated, whereas the trading volumes of industry and information technology sectors are comparatively less correlated.

Since the breakdown of the Bretton Woods system in the early 1970s, the foreign exchange market has become an important focus of both academic and practical research. There are many reasons why FX is important, but one of most important aspects is the determination of foreign investment values. Therefore, FX serves as the backbone of international investments and global trading. Additionally, because fluctuations in FX affect the value of imported and exported goods and services, such fluctuations have an important impact (...) on the economic competitiveness of multinational corporations and countries. Therefore, the volatility of FX rates is a major concern for scholars and practitioners. Forecasting FX volatility is a crucial financial problem that is attracting significant attention based on its diverse implications. Recently, various deep learning models based on artificial neural networks have been widely employed in finance and economics, particularly for forecasting volatility. The main goal of this study was to predict FX volatility effectively using ANN models. To this end, we propose a hybrid model that combines the long short-term memory and autoencoder models. These deep learning models are known to perform well in time-series prediction for forecasting FX volatility. Therefore, we expect that our approach will be suitable for FX volatility prediction because it combines the merits of these two models. Methodologically, we employ the Foreign Exchange Volatility Index as a measure of FX volatility. In particular, the three major FXVIX indices from 2010 to 2019 are considered, and we predict future prices using the proposed hybrid model. Our hybrid model utilizes an LSTM model as an encoder and decoder inside an autoencoder network. Additionally, we investigate FXVIX indices through subperiod analysis to examine how the proposed model’s forecasting performance is influenced by data distributions and outliers. Based on the empirical results, we can conclude that the proposed hybrid method, which we call the autoencoder-LSTM model, outperforms the traditional LSTM method. Additionally, the ability to learn the magnitude of data spread and singularities determines the accuracy of predictions made using deep learning models. In summary, this study established that FX volatility can be accurately predicted using a combination of deep learning models. Our findings have important implications for practitioners. Because forecasting volatility is an essential task for financial decision-making, this study will enable traders and policymakers to hedge or invest efficiently and make policy decisions based on volatility forecasting.

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

This article provides current Schwartz Values Survey (SVS) data from samples of business managers and professionals across 50 societies that are culturally and socioeconomically diverse. We report the society scores for SVS values dimensions for both individual- and societal-level analyses. At the individual-level, we report on the ten circumplex values sub-dimensions and two sets of values dimensions (collectivism and individualism; openness to change, conservation, self-enhancement, and self-transcendence). At the societal-level, we report on the values dimensions of embeddedness, hierarchy, mastery, affective (...) autonomy, intellectual autonomy, egalitarianism, and harmony. For each society, we report the Cronbach’s α statistics for each values dimension scale to assess their internal consistency (reliability) as well as report interrater agreement (IRA) analyses to assess the acceptability of using aggregated individual level values scores to represent country values. We also examined whether societal development level is related to systematic variation in the measurement and importance of values. Thus, the contributions of our evaluation of the SVS values dimensions are two-fold. First, we identify the SVS dimensions that have cross-culturally internally reliable structures and within-society agreement for business professionals. Second, we report the society cultural values scores developed from the twenty-first century data that can be used as macro-level predictors in multilevel and single-level international business research.

Background Conventional consent practices face ethical challenges in continuously evolving digital health environments due to their static, one-time nature. Dynamic consent offers a promising solution, providing adaptability and flexibility to address these ethical concerns. However, due to the immaturity of the concept and accompanying technology, dynamic consent has not yet been widely used in practice. This study aims to identify the facilitators of and barriers to adopting dynamic consent in real-world scenarios. Methods This scoping review, conducted in December 2022, adhered (...) to the PRISMA Extension for Scoping Reviews guidelines, focusing on dynamic consent within the health domain. A comprehensive search across Web of Science, PubMed, and Scopus yielded 22 selected articles based on predefined inclusion and exclusion criteria. Results The facilitators for the adoption of dynamic consent in digital health ecosystems were the provision of multiple consent modalities, personalized alternatives, continuous communication, and the dissemination of up-to-date information. Nevertheless, several barriers, such as consent fatigue, the digital divide, complexities in system implementation, and privacy and security concerns, needed to be addressed. This study also investigated current technological advancements and suggested considerations for further research aimed at resolving the remaining challenges surrounding dynamic consent. Conclusions Dynamic consent emerges as an ethically advantageous method for digital health ecosystems, driven by its adaptability and support for continuous, two-way communication between data subjects and consumers. Ethical implementation in real-world settings requires the development of a robust technical framework capable of accommodating the diverse needs of stakeholders, thereby ensuring ethical integrity and data privacy in the evolving digital health landscape.

Background: An association between gaming disorder and the symptoms of common mental disorders is unraveled yet. In this preregistered study, we quantitatively synthesized reliability, convergent and discriminant validity of GD scales to examine association between GD and other constructs.Methods: Five representative GD instruments were chosen based on recommendations by the previous systematic review study to conduct correlation meta-analyses and reliability generalization. A systematic literature search was conducted through Pubmed, Proquest, Embase, and Google Scholar to identify studies that reported information on (...) either reliability or correlation with related variables. 2,124 studies were full-text assessed as of October 2020, and 184 were quantitatively synthesized. Conventional Hedges two-level meta-analytic method was utilized.Results: The result of reliability generalization reported a mean coefficient alpha of 0.86 and a mean test-retest estimate of 0.86. Estimated effect sizes of correlation between GD and the variables were as follows: 0.33 with depression, 0.29 with anxiety, 0.30 with aggression, –0.22 with quality of life, 0.29 with loneliness, 0.56 with internet addiction, and 0.40 with game playtime, respectively. The result of moderator analyses, funnel and forest plots, and publication bias analyses were also presented.Discussion and Conclusion: All five GD instruments have good internal consistency and test-retest reliability. Relatively few studies reported the test-retest reliability. The result of correlation meta-analysis revealed that GD scores were only moderately associated with game playtime. Common psychological problems such as depression and anxiety were found to have a slightly smaller association with GD than the gaming behavior. GD scores were strongly correlated with internet addiction. Further studies should adopt a rigorous methodological procedure to unravel the bidirectional relationship between GD and other psychopathologies.Limitations: The current study did not include gray literature. The representativeness of the five tools included in the current study could be questioned. High heterogeneity is another limitation of the study.Systematic Review Registration: [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42020219781]. (shrink)

BackgroundThe COVID-19 pandemic has changed the healthcare landscape drastically. Stricken by sharp surges in morbidity and mortality with resource and manpower shortages confounding their efforts, the medical community has witnessed high rates of burnout and post-traumatic stress amongst themselves. Whilst the prevailing literature has offered glimpses into their professional war, no review thus far has collated the deeply personal reflections of physicians and ascertained how their self-concept, self-esteem and perceived self-worth has altered during this crisis. Without adequate intervention, this may (...) have profound effects on their mental and physical health, personal relationships and professional efficacy.MethodsWith mentions of the coronavirus pervading social media by the millions, this paper set out to collate and thematically analyse social media posts containing first-person physician reflections on how COVID-19 affected their lives and their coping mechanisms. A consistent search strategy was employed and a PRISMA flowchart was used to map out the inclusion/exclusion criteria.ResultsA total of 590 social media posts were screened, 511 evaluated, and 108 included for analysis. Salient themes identified include Disruptions to Personal Psycho-Emotional State, Disruptions to Professional Care Delivery, Concern for Family, Response from Institution, Response from Society and Coping Mechanisms.ConclusionIt is evident that the distress experienced by physicians during this time has been manifold, multi-faceted and dominantly negative. Self-concepts were distorted with weakened self-esteem and perceived self-worth observed. The Ring Theory of Personhood (RToP) was adopted to explain COVID-19’s impact on physician personhood as it considers existential, individual, relational and social concepts of the self. These entwined self-concepts serve as ‘compensatory’ to one another, with coping mechanisms buffering and fortifying the physician’s overall personhood. With healthcare institutions playing a vital role in providing timely and targeted support, it was further proposed that a comprehensive assessment tool based on the RToP could be developed to detect at-risk physicians and evaluate the presence and effectiveness of established support structures.

In lieu of an abstract, here is a brief excerpt of the content:Art as a Political Act:Expression of Cultural Identity, Self-Identity, and Gender by Suk Nam Yun and Yong Soon MinHwa Young Choi Caruso (bio)IntroductionA number of artists of color, including Asian American women, are creating art from the basis of their lived experiences. Within minority groups searching for their cultural identity, establishing self-identity is an important process. For various psychological and sociological reasons, artists seem inspired to seek (...) deeper meaning and a broader participation in cultural work.1 Asian American women artists, in particular, are currently making art as a means of exploring self-identity, cultural identity, and gender issues. Korean/Korean American minority women artists are creating art as a reaction to their cultural upbringing, which questions issues of identity, gender, ethnicity, politics, cultural, and socioeconomic status. These contemporary artists are breaking away from traditional cultural expectations and overcoming social barriers as artists, women, and Koreans/Korean Americans. With the growing public awareness of women's consciousness and sense of self as women in Korea and as an ethnic minority in America, these artists are redefining their identity. Despite the traditional patriarchal Confucian hierarchy; lack of social, institutional, and political support; and stereotypic gender, cultural, and socioeconomic status expectations for women, a few have stepped out of their traditional roles as women and have become successful artists in Korea and America.The artworks of these artists are worthy of investigation because they appear to be a culturally, socially, and politically motivated artistic expression of the complex multifaceted Korean/Korean American life experiences as women and as Korean immigrant members of a cultural (ethnic) minority in American society. Therefore, two main research questions can be posed: [End Page 71]• Given that art can be constructed out of layers of different experiences and influences, to what extent do the dimensions of cultural identity, self-identity, and gender interweave and contribute to the function of art as a political act for Korean/Korean American women artists?• How do Korean/Korean American cultural, social, and female experiences influence the artistic expression of Korean/Korean American women artists?In order to answer these questions, I selected case study methodology2 and adapted elements of interpretive biography,3 and narrative approaches as developed by Wallace and Gruber.4 According to Denzin,5 interpretive biography involves the collection and analysis of personal experiences, life documents, stories, accounts, and narratives that describe turning-point moments in individuals' lives. Denzin argues that personal experiences and personal stories are derived from a larger cultural, ideological, and historical context. The intent of the biographical project is to problematize the social, economic, cultural, structural, and historical forces that shape, distort, and otherwise alter lived experiences.By using narrative case study methods, I explore elements of self-identity formation, cultural identity, gender issues, personal thoughts, artistic expression, meaning of artworks, professional achievement, and life circumstances. I examine each participant's life in the Korean and American historical, cultural, social, and political environments. I interpret participants' outer lives (what they do) and inner lives (feelings, thoughts, inner self) to capture their deep, profound life experiences. I examine salient themes of their art expression and how the role of art and artistic activity is a part of political, cultural, social, and feminist activism. I further investigate their professional activities in order to identify the multiple roles that contribute to personal and professional identity formation.For the purpose of this study, I selected the contemporary Korean woman artist Suk Nam Yun and the contemporary Korean American woman artist Yong Soon Min as primary participants. These two women artists, despite many social and cultural barriers, chose to become artists; feminists; and social, cultural, and political activists; in addition to fulfilling traditional Korean family and domestic roles. Yun and Min are regarded as the leading contemporary Korean/Korean American women artists whose artworks deal with issues of cultural, social, feminist, political, and hybrid identity and art as political activism.Lippard acknowledges that visual images play an increasingly important role in society.6 Art that connects everyday experience with social critique and creative expression becomes a vital means of reflecting upon the nature of society and social existence.7 Artworks can function as...
