Nonlinear Predictive Models for Multiple Mediation Analysis: With an Application to Explore Ethnic Disparities in Anxiety and Depression Among Cancer Survivors

Mediation analysis allows the examination of effects of a third variable (mediator/confounder) in the causal pathway between an exposure and an outcome. The general multiple mediation analysis method (MMA), proposed by Yu et al., improves traditional methods (e.g., estimation of natural and controlled direct effects) to enable consideration of multiple mediators/confounders simultaneously and the use of linear and nonlinear predictive models for estimating mediation/confounding effects. Previous studies find that compared with non-Hispanic cancer survivors, Hispanic survivors are more likely to endure anxiety and depression after cancer diagnoses. In this paper, we applied MMA on MY-Health study to identify mediators/confounders and quantify the indirect effect of each identified mediator/confounder in explaining ethnic disparities in anxiety and depression among cancer survivors who enrolled in the study. We considered a number of socio-demographic variables, tumor characteristics, and treatment factors as potential mediators/confounders and found that most of the ethnic differences in anxiety or depression between Hispanic and non-Hispanic white cancer survivors were explained by younger diagnosis age, lower education level, lower proportions of employment, less likely of being born in the USA, less insurance, and less social support among Hispanic patients.     

Psychometric Models of Small Group Collaborations

The social combination theory of group problem solving is used to extend existing psychometric models to collaborative settings. A model for pairwise group work is proposed, the implications of the model for assessment design are considered, and its estimation is addressed. The results are illustrated with an empirical example in which dyads work together on a twelfth-grade level mathematics assessment. In conclusion, attention is given to avenues of research that seem most fruitful for advancing current initiatives concerning the assessment of collaboration, teamwork, and related constructs.     

Does ‘Ought’ Imply ‘Might’? How (not) to Resolve the Conflict between Act and Motive Utilitarianism

Utilitarianism has often been understood as a theory that concerns itself first and foremost with the rightness of actions; but many other things (e.g., moral rules, motives, laws, etc.) are also properly subject to moral evaluation, and utilitarians have long understood that the theory must be able to provide an account of these as well. In a landmark article from 1976, Robert Adams argues that traditional act utilitarianism faces a particular problem in this regard. He argues that a on a sensible utilitarian account of the rightness of an agent’s motives, right motives will sometimes conflict with right actions, leaving the theory internally incoherent. The puzzle Adams raises has received a good deal of attention but few proposed solutions. Fred Feldman, however, has offered a solution that seems to be gaining adherents. In this paper I argue that Feldman’s approach cannot succeed. At bottom, it relies on a version of the principle that ‘ought’ implies ‘can’—and subsequently an account of an agent’s alternatives—that is far too restrictive to be plausible. Despite the failure of this solution, however, I argue that the conflict Adams develops is not as theoretically troubling as he suggests. While traditional act utilitarianism may fail for other reasons, it will not fail due to the conflict between acts and motives.     

Moods,Colored Lenses,and Emotional Disconnection: a Comment on Gallegos

In “Moods Are Not Colored Lenses: Perceptualism and the Phenomenology of Moods” (2017) Francisco Gallegos presents a challenge to popular view about the phenomenology of being in a mood that he calls “perceptualism”. In this essay, I offer a partial defense of perceptualism about moods and argue that perceptualism and Gallegos’s preferred Heideggerian alternative need not be viewed as in opposition to one another.     

<Emphasis Type="Bold">W</Emphasis><Emphasis Type="Bold">ang</Emphasis><Emphasis Type="Bold">Fuzhi’s Criticism of Buddhism and Its Limitations</Emphasis>

Wang Fuzhi’s 王夫之 remarks on Buddhism have not been given sufficient attention despite increasing research on him. The few works on this topic either focus on just one aspect of his view of Buddhism or fail to disclose the purpose and uniqueness of his attack of it. This essay analyzes his view of Buddhism comprehensively, in particular his insight into the paradox of Buddhist universal love and his rejection of Buddhist retribution and reincarnation from Confucian righteousness and qi 氣-monism. In addition, it also explores the reason, context, and limitations of his criticism, that is, his reaction to the popular approach of “understanding Confucian classics through learning Buddhism” in the late Ming 明, his response to Zongmi’s 宗密 criticism of Confucian cosmology and human nature, and his misunderstanding of some Buddhist concepts. Yet his criticism is still illuminating to our understanding of the interaction of Confucianism with Buddhism and other religions.     

Maker Cultures and the Prospects for Technological Action

Supported by easier and cheaper access to tools and expanding communities, maker cultures are pointing towards the ideas of (almost) everyone designing, creating, producing and distributing renewed, new and improved products, machines, things or artefacts. A careful analysis of the assumptions and challenges of maker cultures emphasizes the relevance of what may be called technological action, that is, active and critical interventions regarding the purposes and applications of technologies within ordinary lives, thus countering the deterministic trends of current directions of technology. In such transformative potential, we will explore a set of elements what is and could be technological action through snapshots of maker cultures based on the empirical research conducted in three particular contexts: the Fab Lab Network, Maker Media core outputs and initiatives such as Maker Faires, and the Open Source Hardware Association (OSHWA). Elements such as control and empowerment through material engagement, openness and sharing, and social, cultural, political and ethical values of the common good in topics such as diversity, sustainability and transparency, are critically analysed.     

Condom Use Among South African University Students in the Province of KwaZulu-Natal

South Africa has one of the highest HIV infection rates in the world, with young people particularly affected. Condoms are an effective preventative method against HIV among sexually active adults. This study assessed the level of condom usage among university students in South Africa and their attitudes towards condom usage, negotiation efficacy and confidence in condom usage. It was a cross-sectional study conducted amongst South African university students living at the university residences. Students were randomly selected and required to complete a self-administered questionnaire. The mean age of participants (n?=?441) was 22.7?±?4.3 years. The mean age of sexual debut was 17.7?±?3.0 years with 1.4?±?1.47 (range 0–13) current partners. Less than half of the students used a condom at sexual debut and only 28.5% used condoms during recent sexual activity. Those students who used a condom at first sexual intercourse had marginally more positive attitudes about condom usage than those who did not do so (p?=?0.056). Students with a single current partner had more positive attitudes about condom usage than those with multiple current partners (p?=?0.021). Only 32.5% (n?=?127) of the students were very confident in using condoms. Similarly, only 33.0% (n?=?130) of the participants felt that they could definitely negotiate condom use with their partners. We conclude that condom use among South African students is low and that they lack the confidence to use condoms. We recommend that programmes to step up condom use must also incorporate educational interventions on usage.     

Eknath Easwaran’s Mantram and Passage Meditation as Applied Indian Psychology: Psycho-Spiritual and Health Effects

We review the life and legacy of Eknath Easwaran (1910–1999) from the perspective of modern and Indian Psychology. A Kerala-born professor of English literature, Easwaran in 1959 travelled to the USA where he taught a system of eight spiritual practices known as passage meditation (PM). Its characteristic features include its meditative focus on memorized inspirational passages and using mantram repetition as a primarily “portable” practice throughout the day. The PM method is distinctive in emphasizing the principle, otherwise neglected in the modern psychology of meditation, that “we become what we meditate on”—a principle that possesses a basis in traditional Indian sources that include the Vedas, Puranas, Adi ?a?kara, and Ramakrishna Paramahamsa. Two major programs of empirical research have evaluated Easwaran’s practices, each publishing multiple randomized controlled trials. We summarize findings from (i) studies of the full PM program, and (ii) studies of the Mantram Repetition Program (MRP), based on three of the eight PM points. Randomized evidence links each program to reduced stress, improved mental health, improved mindfulness, and increases in various spiritual measures. We describe ways that PM/MRP empirical research has reflected Indian Psychology perspectives, and suggest that Easwaran’s legacy enriches Indian Psychology with added value in at least three ways: emphasizing the importance of the choice of meditative focus, offering universally framed support for devotional (bhakti) orientations to spirituality, and supplying tools for improving how spiritual diversity is addressed in modern institutions such as health care, schools, and other organizations.     

Preferences for Online Mental Health Services Among Australian and Indian Samples: A Cross-Cultural Comparison

Online mental health services provide a point-of-access to mental healthcare that may otherwise be unavailable or limited, particularly in developing countries. Nevertheless, there is a lack of research into individual differences between those who prefer online mental health services and those who prefer traditional in-person services, and whether these differences vary as a function of culture. This study investigated differences in preferences for online or in-person mental health services on e-health literacy, age, education level, and comfort using the internet in a general community sample recruited from Australia and India. A total of 487 participants (31.6% male; mean age?=?33.55, SD?=?12.20, range 18–78), 297 Australians and 190 Indians, completed an online or paper-and-pencil survey. A significant negative relationship between age and e-health literacy was found with younger ages associated with higher e-health literacy. Furthermore, e-health literacy scores were significantly higher for the Australian sample. Age, e-health literacy, country-of-residence, education level, and comfort in using the internet did not predict mental health service preference. The results suggest that preference for in-person or online mental healthcare is independent of demographic and cultural factors and indicate that online mental health services may be acceptable to Indian health service consumers.
