A Thurstonian model for the dual pair (4IAX) discrimination method

The Institute for Perception, Richmond, Virginia In the dual pair method, the subject is presented with two stimuli in two pairs: One pair is composed of two samples of the same stimulus; the other pair is composed of two samples of different stimuli, one being the same as that in the identical pair. The task of the judge is to select the most different pair. The psychometric function for the dual pair method is derived and expressed in terms of a singly noncentral beta distribution. A table is provided that connects a measure of the degree of difference, d , to the probability of a correct response. This table assumes an unbiased observer and differencing decision rule. A table is provided to give an estimate of the variance of d¢, the experimental estimate of d. The power of the dual pair method is also investigated, and a formula to determine the sample size required to meet Type I and Type II error specifications is given. The dual pair method appears to be slightly less powerful than the duotrio and the triangular methods. Experimental investigation is needed to explore the dual pair in applied research work.     

SCIENCE MEETS BIBLICAL EXEGESIS IN THE GALILEO AFFAIR

Abstract Although Galileo's venture into theology, as discussed by McMullin, is limited to Galileo's exegesis of Scripture, it can be seen as an important element in a broader role in theology, namely in ecclesiology and in the development of doctrine. From the Council of Trent, the Reformation Council, until today there has been a development in the Church concerning the manner in which Sacred Scripture should be interpreted and as to whether it can be said to be in conflict with our scientific knowledge of nature. Galileo made a significant contribution to this development. With his telescopic observations he was, in fact, undermining the prevailing Aristotelian natural philosophy of his day and was defending the birth of modern science against a mistaken view of Scripture. The Church of his time was not prepared to accept his contribution to this theological development. What does this history have to contribute to the challenges we face today in the interactions between science and religious belief?     

When career paths cease to exist: A qualitative study of career behavior in a crisis economy

Using grounded theory methodology, this study examines the ways young professionals describe their career paths in the aftermath of the 2008 Financial Crisis. We interviewed a sample of 29 Greek women professionals (24 to 32 years old) to examine their career behavior during this recession. Findings reveal prevailing effects of professional identity and profession-consistent learning goals on participants' career behavior. Specifically, those individuals without a strong professional identity or profession-consistent learning goals are more likely to anticipate and engage in career activities unrelated to their professions, a group whom we refer to as Shifters. In contrast,     

Old Testament and Church Ministries in Two Ecumenical Dialogues

Abstract: To understand any church institution as founded by Jesus, one must take account of its relationship to his work of bringing the Old Testament revelation and its institutions to their eschatological realization. A sample of the work of recent ecumenical dialogues (BEM and the international Lutheran– Roman Catholic document on church and justification) shows that their discussions of church institutions have failed to do this adequately. This failure has complicated the efforts at unity to which these dialogues intend to contribute. Attention to the Old Testament roots of church institutions can help ecumenical ecclesiology to focus better on some important issues.     

"One Day I Will Make a Good Parent": On The Relationship Between Overparenting and Young Adults’ Early Parenting Representations

Early parenting representations are likely to affect future parenting, and it is therefore important to investigate their predictors. In this study, we focused on one dimension of early parenting representations, i.e., perceived ability to relate well to children (PARC) in young adults who are not yet parents, and examined whether this was associated with their own parents’ overparenting. In addition, we investigated whether this association was mediated by young adults’ attachment styles and perceived general interpersonal problems. Questionnaires were collected from 96 triads (mothers, fathers, young adults; 50% male) comprising intact families. Overparenting dimensions were not consistently associated with PARC. First, significant associations with PARC were observed only for maternal overparenting. Second, higher levels of maternal anticipatory problem solving were significantly associated with lower levels of PARC, whereas higher levels of maternal advice/affect management were significantly associated with higher levels of PARC. These associations were significantly mediated (partially) by levels of secure attachment style and (completely) by levels of dismissive attachment style. Dimensions of maternal overparenting and their interplay with young adult offspring’s attachment might have a part in the formation of young adults’ early parenting representations. Prevention initiatives could be set up to inform young adults’ parents about the drawbacks of overparenting, and young adults themselves about possible coping mechanisms.     

Passion and Gambling: Investigating the Divergent Affective and Cognitive Consequences of Gambling1

Vallerand et al. (2003) developed a theoretical framework of passion where two types of passions are proposed: obsessive and harmonious passion. Obsessive passion is characterized by an internal pressure that pushes the person to engage in the passionate activity, whereas harmonious passion is characterized by the person's choice to engage in the activity. The goal of the present study was to examine the outcomes of these types of passion toward gambling. A total of 554 participants completed instruments assessing their passion toward gambling, as well as several cognitive and affective outcomes. Results indicated that, in general, harmonious passion was associated with positive outcomes, while obsessive passion was related to negative consequences. Results also showed that casino activities accentuated both positive and negative outcomes by fostering both types of passion toward the gambling activity. Conceptual and practical implications are discussed.
