The meaning and computation of causal power: comment on Cheng (1997) and Novick and Cheng (2004)

D. Hume (1739/1987) argued that causality is not observable. P. W. Cheng (1997) claimed to present "a theoretical solution to the problem of causal induction first posed by Hume more than two and a half centuries ago" (p. 398) in the form of the power PC theory (L. R. Novick & P. W. Cheng, 2004). This theory claims that people's goal in causal induction is to estimate causal powers from observable covariation and outlines how this can be done in specific conditions. The authors first demonstrate that if the necessary assumptions were ever met, causal powers would be self-evident to a reasoner--they are either 0 or 1--making the theory unnecessary. The authors further argue that the assumptions the power PC theory requires to compute causal power are unobtainable in the real world and, furthermore, people are aware that requisite assumptions are violated. Therefore, the authors argue that people do not attempt to compute causal power.     

Social identity,attribution, and emotion: Comparisons of Americans,Korean Americans,and Koreans

The social identity of another person, in addition to the social identity of self, can be an important factor affecting the types of attribution judgments and emotions that individuals indicate for the other person. In April 2007, the perpetrator of the shooting incident on the Virginia Tech University campus was identified as a person who emigrated to the USA from Korea at a young age. The current study compared non‐Korean Americans, Korean Americans, Koreans in the USA, and Koreans in Korea in terms of their attributions and emotions concerning the perpetrator and the shooting incident. Participants were asked to indicate (1) the extent to which they attributed the cause of the incident to either American society or the perpetrator, (2) their emotions (e.g., upset), and (3) the extent to which they categorized the perpetrator as an American, a Korean American, or a Korean. The results indicated that non‐Korean Americans were most likely to attribute the cause of the incident to the perpetrator as opposed to American society. Non‐Korean Americans, Korean Americans, and Koreans in the United States had more negative emotions (e.g., unhappy, sad, and upset) about the incident than Koreans in Korea did. The results also indicated that individuals differed in their attributions and emotions depending on how they categorized the perpetrator. For example, categorizing the perpetrator as being a Korean was positively related to Americans’ tendency to hold the perpetrator responsible, while categorizing the perpetrator as being an American was negatively related to the tendency to hold the perpetrator responsible among Koreans in Korea. The findings may imply that social identity theory, intergroup emotion theory, and cultural orientations (e.g., individualism and collectivism) can provide insights into people's reactions to a tragic incident.     

“I didn’t understand their system,and I didn’t know what to do”: Migrant Parents’ Experiences of Mandated Therapy for Their Children

In this phenomenological study, we explored the experiences of migrant parents whose children received mandated therapy in Southern California. Migrants are people who move to a host country either voluntarily as immigrants or involuntarily as refugees. Mandated therapy means that the school or court system required that their children receive services from a mental health provider. Parents often participated by having to take parenting classes and join in some sessions with their children; however, the children were the identified clients. We conducted eight, in-depth interviews with migrant parents. We employed Giorgi and Giorgi’s (Qualitative research in psychology: expanding perspectives in methodology and design. American Psychological Association, Washington, 2003; Qualitative psychology: a practical guide to research methods. Sage, London, 2008) phenomenological psychological research approach to analyze data. Analysis revealed four constituents, which are overarching themes related to the essential structure of the shared phenomenon: (a) migrant parents encountered discrimination and devaluation; (b) migrant parents experienced increased exposure to US culture and the mental health system, which accelerated acculturation; (c) the degree of cultural sensitivity exhibited by providers both positively and negatively influenced participants’ attitudes and perceptions toward mental health services; and (d) migrant parents used their mandated therapy experiences as opportunities to examine their family relationships and to learn new skills and concepts.     

Abnormal diurnal pattern of cortisol secretion in patients after aneurysmal subarachnoid hemorrhage

Substantial evidence suggests that impairment of the hypothalamus?pituitary system can occur following an aneurysmal subarachnoid hemorrhage (aSAH). Given that the diurnal cortisol rhythm is primarily controlled by the hypothalamus?pituitary system, this study examined whether changes in diurnal cortisol rhythm occurred after aSAH. Cortisol concentrations were measured in the saliva samples collected from patients after aSAH and other types of cerebral hemorrhage (non-aSAH) in the post-awakening period and at night (21:00?h), and the cortisol awakening response (CAR) and diurnal cortisol decline were determined. The area under the cortisol curve from immediately after to 45?min after awakening (CARauc) in the aSAH patient group was comparable to that in the non-aSAH or healthy control groups. However, an obvious cortisol peak was not found after the awakening period, and the morning/nighttime cortisol ratio in the aSAH patient group was significantly lower than that in other examined groups due to higher nighttime cortisol concentrations. In aSAH patients, the CARauc and nighttime cortisol concentrations were negatively correlated with the Fisher CT grade. These results indicate that the diurnal cortisol rhythm is not regulated normally after aSAH, and cortisol secretory activity decreases as the volume of subarachnoid bleeding increases. Our findings will be helpful to understand altered hypothalamus?pituitary?adrenal axis function after aSAH.     

Use of the estimated intraclass correlation for correcting differences in effect size by level

In a meta-analysis of intervention or group comparison studies, researchers often encounter the circumstance in which the standardized mean differences (d-effect sizes) are computed at multiple levels (e.g., individual vs. cluster). Cluster-level d-effect sizes may be inflated and, thus, may need to be corrected using the intraclass correlation (ICC) before being combined with individual-level d-effect sizes. The ICC value, however, is seldom reported in primary studies and, thus, may need to be computed from other sources. This article proposes a method for estimating the ICC value from the reported standard deviations within a particular meta-analysis (i.e., estimated ICC) when an appropriate default ICC value (Hedges, 2009b) is unavailable. A series of simulations provided evidence that the proposed method yields an accurate and precise estimated ICC value, which can then be used for correct estimation of a d-effect size. The effects of other pertinent factors (e.g., number of studies) were also examined, followed by discussion of related limitations and future research in this area.     

BETWEEN MT. MORIAH AND MT. GOLGOTHA: How Is Christian Ethics Possible?

In this paper, I explore a new way of understanding Christian ethics by critically interconnecting the theological meanings of the Aqedah (“binding”) narrative of Mt. Moriah and the Passion story of Mt. Golgotha. Through an in‐depth critical‐theological investigation of the relation between these two biblical events, I argue that Christian ethics is possible not so much as a moralization or as a literalistic divine command theory, but rather as a “covenantal‐existential” response to God's will in the impossible love on Mt. Moriah as well as in the Son's willing embrace of God's will on Mt. Golgotha.
