Perceived product instrumentality: the process of scale purification and validation

Perceived product instrumentality (PPI) is a new construct that is proposed as a key process component of a general model of family purchasing behaviour. PPI reflects the degree to which consumers, apprehended as actors of social roles, deem a product to be helpful, facilitative of role performance, compatible with role identity and congruent with the self‐concept. The objective of this paper is threefold: (1) assess the PPI unidimensionality and reliability; (2) purify the PPI scale, and (3) assess its validity. First, a pilot survey was administered to a convenience sample of men and women, who filled in four identical lists of 33 items tapping their attitudes towards durables, and exploratory factor analysis was conducted on each set to explore the overall pattern of the items relationships. Five try‐out pools of different sizes (33, 28, 15, 13 and 9 items) were involved in the analysis. The 15‐item scale was retained. Secondly, a large‐scale survey was administered to 500 couples as part of an extensive research involving comprehensive model testing. Exploratory factor analysis was conducted on the whole sample for reliability and unidimensionality assessment. At times, the analysis is done on men's and women's sub‐samples separately in order to account for eventual differences among both populations. Thirdly, confirmatory factor was conducted, splitting the sample into two random halves: the generation sample and the validation sample. The first half served for the PPI scales purification. In this case, PPI was posited as the latent variable and the scale items were posited as the manifest ones. The second served to validate the PPI theory in a system's framework: PPI was posited as a latent dependent variable while other role orientations variables were posited as latent independent variables.

Double bind: An essay on counselling training

Gerard Egan's problem management and opportunity development model is currently in use training prospective counsellors, social workers, nurses, managers, etc. the skills of helping. This essay attempts, experimentally, to depict in three different ways Egan's work and its relationship to operations of power: (1) from a relatively uncritical stance, (2) from a personal experience stance, and (3) from a social constructionist perspective. The whole piece, taken together, attempts to tackle the issue of theory as practice — to ground/unmask/make present the ways in which we are socialised into a profession and the problems inherent in that process. Two themes run through the work: the double bind created for a student on a counselling course which makes some claim to train around Rogers' core conditions, and which is also assessed/accredited; the connections between theory, training and practices.     

The First-Order Theories of Dedekind Algebras

A Dedekind Algebra is an ordered pair (B,h) where B is a non-empty set and h is an injective unary function on B. Each Dedekind algebra can be decomposed into a family of disjoint, countable subalgebras called configurations of the Dedekind algebra. There are N₀ isomorphism types of configurations. Each Dedekind algebra is associated with a cardinal-valued function on omega called its configuration signature. The configuration signature of a Dedekind algebra counts the number of configurations in the decomposition of the algebra in each isomorphism type.The configuration signature of a Dedekind algebra encodes the structure of that algebra in the sense that two Dedekind algebras are isomorphic iff their configuration signatures are identical. Configuration signatures are used to establish various results in the first-order model theory of Dedekind algebras. These include categoricity results for the first-order theories of Dedekind algebras and existence and uniqueness results for homogeneous, universal and saturated Dedekind algebras. Fundamental to these results is a condition on configuration signatures that is necessary and sufficient for elementary equivalence.     

A Test of Evolutionary and Sociocultural Explanations of Reactions to Sexual Harassment

Although the field of evolutionary psychology has been perceived to generate predictions that are untestable, one potentially falsifiable prediction of the evolutionary approach is that women should be less upset by unwanted sexual advances from high than from low status men. Three experiments tested this hypothesis within a workplace and an academic setting. Across the first two experiments, women and men were actually more upset by perceived sexual harassment from higher than lower status members of the other sex. Results of Study 3 suggested that women only showed this difference when there was a power relationship involved. These results conflict with the evolutionary prediction and support a sociocultural explanation of reactions to sexual harassment; that is, that they are influenced by power differentials.     

Cognitive Induction of Anger and Depression: The Role of Power, Attribution, and Gender

The causes of and contributors to negative emotions have been areas of interest in psychology for decades. Recent work has shown a variety of negative emotions, including anger and depression, to be related. The present study investigated the effects of power, attributional style, and gender on anger and depression using a series of narrative mood inductions presented to 120 undergraduates. Results indicated that participants in the external attribution and low power conditions demonstrated significantly higher levels of postinduction anger than those in other conditions. In addition, the influence of internal attributions on postinduction depression scores approached significance. The effectiveness of the study's mood induction methodology is discussed and suggestions are made for future research.     

Sanctioned social violence: A psychoanalytic view. Part II

This paper is the second in a series of two papers. In Part I, the first paper, the author reviewed the influence on the development of socially sanctioned violence of psychodynamics of group psychology and mass psychology, the regressive pull of ideologies, personality features of social and political leadership, and historical trauma and social crises. In this Part II, the author explores, from a psychoanalytic perspective, the dehumanization processes related to fundamentalist ideologies and terrorism.     

Millennials’ national and global identities as drivers of materialism and consumer ethnocentrism

ABSTRACT

A major effect of globalization is one that occurs on the self-concept. This is especially the case for young consumers, and particularly for millennials. Despite this cohort’s idiosyncrasies, little attention has been paid to the study of their consumer identities, an important aspect of self-concept. The current research addresses this gap by examining the way millennial consumers’ global and national identities help explain two attitudinal outcomes associated with globalization: materialism and consumer ethnocentrism. Data were collected from millennials in two distinct socio-cultural contexts. A key finding suggests that distinct contexts (i.e., collectivist and ethnically homogeneous vs. individualistic and ethnically diverse) exhibit differences in the formation of materialism and consumer ethnocentrism among millennials. Additionally, results indicate that for similar consumer segments, each context’s configuration of millennials shows differences in global and national identities. Implications for future researchers and practitioners are discussed.     

Fruitful Interchange or Polite Chitchat? The Dialogue Between Science and Theology

The demand that epistemic support be explicated as rational compulsion has consistently undermined the dialogue between theology and science. Rational compulsion entails too restrictive a form of epistemic support for most scientific theorizing, let alone interdisciplinary dialogue. This essay presents a less restrictive form of epistemic support, explicated not as rational compulsion but as explanatory power. Once this notion of epistemic support is developed, a genuinely productive interdisciplinary dialogue between theology and science becomes possible. This essay closes by sketching how the Big Bang model from cosmology and the Christian doctrine of Creation can be viewed as supporting each other.     

Preservation Theorems Without Continuum Hypothesis

Many results concerning the equivalence between a syntactic form of formulas and a model theoretic conditions are proven directly without using any form of a continuum hypothesis. In particular, it is demonstrated that any reduced product sentence is equivalent to a Horn sentence. Moreover, in any first order language without equality one now has that a reduced product sentence is equivalent to a Horn sentence and any sentence is equivalent to a Boolean combination of Horn sentences.
