Modelling method effects as individual causal effects

Summary.  Method effects often occur when different methods are used for measuring the same construct. We present a new approach for modelling this kind of phenomenon, consisting of a definition of method effects and a first model, the method effect model , that can be used for data analysis. This model may be applied to multitrait–multimethod data or to longitudinal data where the same construct is measured with at least two methods at all occasions. In this new approach, the definition of the method effects is based on the theory of individual causal effects by Neyman and Rubin. Method effects are accordingly conceptualized as the individual effects of applying measurement method j instead of k . They are modelled as latent difference scores in structural equation models. A reference method needs to be chosen against which all other methods are compared. The model fit is invariant to the choice of the reference method. The model allows the estimation of the average of the individual method effects, their variance, their correlation with the traits (and other latent variables) and the correlation of different method effects among each other. Furthermore, since the definition of the method effects is in line with the theory of causality, the method effects may (under certain conditions) be interpreted as causal effects of the method. The method effect model is compared with traditional multitrait–multimethod models. An example illustrates the application of the model to longitudinal data analysing the effect of negatively (such as 'feel bad') as compared with positively formulated items (such as 'feel good') measuring mood states.     

In search for the ideal coopetition partner: an experimental study

Coopetition (collaboration between competitors) has the potential to provide major benefits or losses to participating firms. Entering a partnership with a competitor is a strategic decision with potential long-term consequences rendering the choice of partner of key importance. Existing research has investigated partner’s strategic attributes, but not how the inter-organizational factors between coopetiting firms affect partner selection and on which layers those effects occur. We use a vignette study for reducing this gap, representing the first experimental study on the field of coopetition research. The results from our study from 874 evaluations of potential coopetition partnerships by key informants from Austria, Germany, Liechtenstein and Switzerland offer insights into how the possible partner’s role, resource alignment and the planned activity affect partner selection. The findings suggest that the partner’s role in the markets—i.e. whether it is a direct or an indirect competitor—is critical in partner selection. The planned activity and resource configuration is also found to influence the evaluation of possible coopetition partners. Overall, the results of this first experimental study in coopetition research provide important implications to both theory and practice.

Measuring the Immeasurables: Development and Initial Validation of the Self-Other Four Immeasurables (SOFI) Scale Based on Buddhist Teachings on Loving Kindness,Compassion, Joy,and Equanimity

Multiple measures exist that examine the attentional aspects of meditation practice, but measurement of the compassion component is relatively understudied. This paper describes the development and initial validation of a scale designed to measure application of the four immeasurable qualities at the heart of Buddhist teachings: loving kindness, compassion, joy and acceptance toward both self and others. Our analyses suggest four distinct subscales: positive qualities toward self, positive qualities toward others, negative qualities toward self and negative qualities toward others. Initial examination of reliability and validity showed high internal consistency for the subscales as well as strong concurrent, discriminant, and construct validity. We believe the Self-Other Four Immeasurables (SOFI) scale has broad utility for research on mindfulness, positive psychology, and social psychology.     

Ageing of a giant: a stochastic population forecast for China, 2006–2060

This paper presents a stochastic population forecast for China with a special emphasis on population ageing. The so-called scaled model for error was used to quantify the uncertainty attached to the population predictions. Data scarcity was a major problem in the specification of the expected error of the population forecast. Therefore, the error structures estimated for European countries were used with some modifications, taking into account the large size and heterogeneity of the Chinese population. The stochastic forecast confirms the expectation of extremely rapid population ageing during the first half of the twenty-first century in China. The old age dependency ratio (OADR) will certainly increase. Simply maintaining the current demographic rates (no international migration) would drive the OADR to 0.42 in 2060, four times the current level. Including expected declines in mortality and net outmigration in the projection would increase the median OADR in 2060 to 0.59, with a 80% prediction interval of [0.47, 0.75]. In particular, the oldest-old population will grow much faster than any other age group. This development has major implications for policy-making in China.

Sensory language (SDM) to foster empathy in social work students

Assessment and management of emotional situations are generally discussed in academic studies in the field of social work through verbal interventions, while the art of developing awareness to nonverbal feelings has yet to see widespread use. Sensory experience based on nonverbal communication and body language can highlight complex feelings and problems that the social worker confronts. The aim of this study was to examine the effect of an intervention of sensory body language using a modified Sherborne Developmental Movement (SDM) model, in a course for social work students. The course’s multidimensional process involved cognitive and affective components of understanding and identifying thoughts, feelings, and emotional states of others. The intervention combined art activity and focusing to foster empathy among social work students in the group setting. Twenty social work students attending college in the north of Israel participated in the course, writing reflective diaries throughout the course, which were collected and analyzed. The findings suggest that sensory language and movement through the group experience enhanced social work students’ empathy and their awareness of its importance for practice. Learning to be empathic through nonverbal communication also challenged perceived barriers to empathy such as cultural and language differences.     

“Live in Israel. Live the Dream”: Identity,Belonging, and Contemporary American Jewish Migration to Israel

Most current sociological literature on migration examines international moves to the United States and internal migration. Scant research addresses religious migration out of the United States. Utilizing in-depth, semi-structured interviews, we explore motivations behind recent American Jewish migration to Israel and how Jewish identity plays a role in the decision to move. We find that a combination of religious and cultural factors, Zionism, social networks, and the desire for a new start play a major role in motivating migration to Israel. Jewish identity is a common thread across these motivations. Many participants created a strong bond between their Judaism and Israel, viewing their connection to Israel as a way to belong to a larger community and demonstrate their attachment to Judaism. We discuss the implications for studying religious emigration from the United States that move beyond traditional economic models.     

Examination and visualisation of the simplifying assumption for vine copulas in three dimensions

Vine copulas are a highly flexible class of dependence models, which are based on the decomposition of the density into bivariate building blocks. For applications one usually makes the simplifying assumption that copulas of conditional distributions are independent of the variables on which they are conditioned. However this assumption has been criticised for being too restrictive. We examine both simplified and non‐simplified vine copulas in three dimensions and investigate conceptual differences. We show and compare contour surfaces of three‐dimensional vine copula models, which prove to be much more informative than the contour lines of the bivariate marginals. Our investigation shows that non‐simplified vine copulas can exhibit arbitrarily irregular shapes, whereas simplified vine copulas appear to be smooth extrapolations of their bivariate margins to three dimensions. In addition to a variety of constructed examples, we also investigate a three‐dimensional subset of the well‐known uranium data set and visually detect the fact that a non‐simplified vine copula is necessary to capture its complex dependence structure.     

“We are not strippers”: How Belly Dancers Manage a (Soft) Stigmatized Serious Leisure Activity

Most stigma research examines people who engage in deviant activities or possess visible and permanent discredited attributes, which lead to “hard” or severe consequences. Existing leisure studies focus on the benefits of leisure pursuits. Less attention is paid to the potential costs associated with serious leisure, such as “soft” stigma. The snubs and slight embarrassments resulting from soft stigma may jeopardize the rewards people receive from participating in leisure, such as a sense of identity, self‐worth, and pride. Using interviews with seventy‐four female belly dancers, most of whom belly dance as a form of “serious leisure,” this article examines how dancers manage perceptions that they are erotic dancers. Results show that dancers use an interesting set of stigma management techniques and new forms of some existing management strategies to simultaneously protect themselves and enhance the reputation of the group. Implications for how people negotiate soft stigma associated with serious leisure are discussed.     

Commemorating Narratives of Violence: The Yitzhak Rabin Memorial Day in Israeli Schools

Based on an analysis of ceremonies in thirty Israeli schools, this article focuses on the way in which the Israeli educational system grappled with the problematic narrative of Yitzhak Rabin's assassination, a narrative that challenged the system's basic assumptions about commemorative logic. The challenge was met by playing with the narrative's multiple frames of meaning (protagonist, act, and context). Rabin's image and biography were elevated and nearly sanctified, while the assassination itself was individualized and the context in which it occurred was de-politicized and virtually bypassed. Thus, the commemoration of even a problematic narrative of political violence could be held on school premises, where it could meet the challenge of enhancing unity and proud national identity. Even events that are not heroic, even shameful, and which do not enjoy a consensus can be reframed in a consensual manner.
