Understanding physical activity behavior in African American and Caucasian college students: an application of the theory of planned behavior

Only 30% of college students meet the recommended amount of physical activity (PA) for health benefits, and this number is lower for African American students. Moreover, the correlates of PA may vary by ethnicity. OBJECTIVE: In the present study, the authors tested the utility of the theory of planned behavior for explaining PA intentions and behavior in Caucasian and African American students. PARTICIPANTS AND METHODS: Participants were 238 African American (M age = 20.05 years, SD = 2.28) and 197 Caucasian (M age = 19.50 years, SD = 2.28) students who completed a baseline theory of planned behavior questionnaire and a follow-up PA measure 1 week later. RESULTS: Hierarchical regression analyses showed that affective (beta = .23) and instrumental (beta = .28) attitudes and perceived behavioral control (beta = .59) were significantly predictive of intention for the Caucasian students, whereas affective attitude (beta = .18) and perceived behavioral control (beta = .56) were significant for African American students. Furthermore, intention (beta = .33) was the lone significant predictor of PA for Caucasian students, whereas perceived behavioral control (beta = .23) was the significant predictor of PA for African American students. CONCLUSIONS: These data suggest that practitioners may need to consider ethnicity when developing PA interventions for college students based on the theory of planned behavior.     

The Personal Is Scientific,the Scientific Is Political: The Public Paradigm of the Environmental Breast Cancer Movement

This paper introduces the concept of boundary movements to characterize the distinctive growth and strategies of movements involving citizen/science alliances to contend with environmentally related illnesses. This concept is applied to a case study of the environmental breast cancer movement, which has induced changes in treatment options and public perception of breast cancer. Since the early 1990s, a segment of this movement has consistently criticized the traditional paradigms governing research, the epistemology of breast cancer, and popular understandings. Against the traditional focus on genetics, lifestyles, and personal responsibility, this segment's broader messages stress environmental causation and women's participation in science and politics.

Technological change,technostress, and industrial humanism

The need for more humanistic imperatives in the management of technological change must be our mandate for corporate and human excellence. Industrial Humanism is our new management creed. The imperatives of humanism such as identity, integrity, self-actualization, individuality, potentiality, responsibility, autonomy, caring, trust, meaning, self-esteem, and character growth must be enriched as the corporation moves to adopt new technologies. The imperatives of technology based on technical rationality, means-ends chain, and industrial engineering methods for programming the workflow for efficiency contain the potential for job alienation, boredom, and technostress. A new psychological contract that integrates both technical and humanistic imperatives is the challenge for the information society. This is an ethical imperative for managing technological change.     

Using Two Intersubjective Perspectives in Combat Deployment: A Military Mental Health Professional’s Experience

The stress and demands of combat deployment create challenges for a military mental health provider (MMHP) to operate in a helper role in an environment adverse to the helping process. A case is presented featuring the experience of a MMHP while deployed to establish the existence of two types of intersubjective space in a combat environment. Modern attachment theory and interpersonal neurobiology are used as a theoretical framework, and concepts of emotional self-regulation, implicit communication, and attunement are applied to the case. The work of the MMHP is shown within and between the two types of intersubjective space and emphasize the seizing of unexpected clinical moments. The MMHP must remain emotionally regulated to participate in the implicit communicative process and rapidly form a therapeutic relationship. Creative and improvisational methods are demonstrated by the MMHP that challenge rigid adherence to clinical models. Applicability is significant to the specialty field of MMHP’s to improve deployment preparation, clinical skill development, and personal health management. Work with veterans can be enhanced by understanding deployment experiences and recognizing the importance of attunement by regulating affect for both the provider and client.     

Sounding the Holocaust,silencing the city: memorial soundscapes in today’s Berlin

Silence appears frequently in discourses of the Holocaust – as a metaphorical absence, a warning against forgetting, or simply the only appropriate response. But powerful though these meanings are, they often underplay the ambiguity of silence’s signifying power. This article addresses the liminality of silence through an analysis of its richly textured role in the memorial soundscapes of Berlin. Beyond an aural version of erasure, unspeakability, or the space for reflection upon it, I argue that these silent spaces must always be heard as part of their surrounding urban environment, refracting wider spatial practices and dis/order. When conventions are reversed – when the present is silent – the past can resound in surprising and provocative ways, collapsing spatial and temporal borders and escaping the ritualized boundaries of formal commemoration. This is explored through four different memorial situations: the disturbing resonances within the Holocaust Memorial; the transgressive processes of a collective silent walk; Gleis 17 railway memorial’s opening up of heterotopic ‘gaps’ in time; and sounded/silent history in the work of singer Tania Alon. Each of these examples, in different ways, frames a slippage between urban sound and memorial silence, creating a parallel symbolic space that the past and the present can inhabit simultaneously. In its unpredictable fluidity, silence becomes a mobile and subversive force, producing an imaginative space that is ambiguous, affective and deeply meaningful. A closer attention to these different practices of listening disrupts a top-down, strategic discourse of silence as conventionally emblematic of reflection and distance. The contemporary urban soundscape that slips through the silent cracks problematizes the narrative hegemony of memorial itself.
