Differential impact of Web site content: Exploring the influence of source (public relations versus news), modality,and participation on college students’ perceptions

This experiment examined the impact of source, modality, and participation on perceptions of credibility, salience, attitudes, and general Web site evaluation. The data showed no significant differences between online stories coming from either public relations or news sources on any of the study's dependent variables. However, significant differences did emerge for the effects of multimedia and audience engagement.     

Romanian social workers facing the challenges of neo-liberalism

ABSTRACT

With a history of almost 90 years, professional social work in Romania once flourished up until World War II. The Communist Party disbanded the profession in 1968 and it was reinstated after the fall of the Iron Curtain in 1989. Within the context of the socio-economic transition from a centralised to a free-market economy, Romanian social policy and social work have evolved from a Marxist/socialist-type ideology, one that advocates for state intervention, to a libertarian/neo-liberal-type ideology, which promotes both state withdrawal from welfare provision and individuals taking responsibility for their own welfare. These two trends continue to co-exist subject to sometimes divergent forces such as international institutions and internal Romanian social pressures. Using a qualitative approach, we explore how Romanian social workers are adapting to the neo-liberal realities and identify three types of perceived challenges: 1. those related to regulation, 2. linked with collaboration in social work activity and 3. those related to the social worker-client relationship. Under neo-liberal pressures, the social worker's role of agent of social change becomes marginalised in daily practice, leaving little power to influence agency policies that negatively impact clients.     

Changing informal institutions via mimesis: Gender equality in marriage proposals

Marriage equality has exposed how the institution of marriage is changing, but less attention has been given to how informal institutions around heterosexual marriage rituals are affected by a growing demand for gender equality. By applying institutional theory and feminist institutionalism to the context of women proposing to their male partners, this paper observes how shifts in gender norms change heteronormative institutions. Drawing from interviews with women who proposed to men and a virtual ethnography, we describe how reverse proposals can set precedence for emulation of practices or mimetic isomorphism. We therewith contribute to institutional theory in threefold ways. First, we describe how mimetic isomorphism introduces new standards and norms into a highly traditional institution. Second, we show how this integration of new standards and norms serves this patriarchal institution to remain relevant and appear progressive. Finally, we contend that this tension of joining a patriarchal institution but doing so in a subversive manner represents a double bind for women who are encouraged by society to formalize their heteronormative relationships through marriage and yet chastised for initiating this themselves.     

Recall searching with and without recall

We revisit the sequential search problem by Hey (J Econ Behav Organ 8:137–144, 1987). In a 2 \(\times \) 2 factorial design, varying fixed and random cost treatments with and without recall, we address open research questions that were originally stated by Hey (1987). Our results provide clear evidence for Hey’s (1987) conjecture that recall negatively affects performance in sequential search. With experience, however, search behavior with and without recall converges toward the optimal reservation rule. We further find that the utilization of optimal reservation rules is independent from the stochastic nature of the search cost.     

Revisiting the Structure of Subjective Well-Being in Middle-Aged Adults

Subjective well-being is a broad, multifaceted construct comprising general satisfaction with life, satisfaction with life domains (health, family, people, free time, self, housing, work, and finances), positive affect, and negative affect. Drawing on representative data from middle-aged adults (N = 738), the authors used three different structural models to analyze the interrelationships among these facets of subjective well-being. In a top-down model, a single factor representing global subjective well-being explained the correlations found among the more specific facets of subjective well-being and exerted the strongest influence on general satisfaction with life, satisfaction with health, and satisfaction with finances. In a bottom-up model, satisfaction with the latter two domains had the strongest effect on global subjective well-being. The authors discuss the implications of their findings for research on subjective well-being.     

Maximum log-likelihood ratio test for a change in three parameter Weibull distribution

Asymptotic behavior of a log-likelihood ratio statistic for testing a change in a three parameter Weibull distribution is studied. It is shown that if a shape parameter α>2$\alpha >2$ the law of iterated logarithm for maximum-likelihood estimators is still valid and the log-likelihood testing statistic is asymptotically distributed (after an appropriate normalization) according to a Gumbel distribution.     

Women’s mobilisation in the Portuguese revolution: context and framing strategies

This article examines the role of women’s mobilisations related to the 1974 Portuguese revolution. An in-depth analysis of three women’s organisations through archival research and interviews with participants highlights the ways in which they participated in a cycle of contention between 1974 and 1977. Examination of framing strategies demonstrates the effects of political and cultural context. In particular, I demonstrate that movement–party alliances informed and constrained the diagnostic and prognostic frames of women’s movements on feminism and the revolution. Opportunity structures are shown to vary for different organisations within the same cycle of contention. Facing relatively closed opportunities, two of these organisations pursued framing strategies that articulated with the Left-dominated master frame of the cycle in order to carve out spaces for gender-specific demands while rejecting the label of feminism. The third organisation, instead, presented a countercultural frame that alienated the organisation from party and movement allies. Unable to overcome ideological divisions and rivalries, the three organisations perceived each other as competitors, rather than potential allies. While party–movement cooperation contributed to the emergence of a fractionalised women’s movement, it also provided important support structures to aid women’s organisations to mobilise in a cultural and political context that was closed to feminist demands.
