Head Cocoons

ABSTRACT

Listening with the aid of headphones was at the heart of the early radio culture of the 1920s. After those years, however, earphones became the exception as loudspeakers became the norm. For quite some time thereafter, the wiring of hearing was limited to the use of monaural earbuds in situations where the use of loudspeakers would have disturbed others. In West Germany, the binaural headphone started to make a comeback in the late 1960s due to the growing fragmentation of family life along with the widening range of electronic leisure possibilities and the rise of hi-fi culture. It was only at the end of the twentieth century, however, that binaural headphone listening emerged as the dominant culture of listening and caught up with the burgeoning mobile urban life style.

Taking the case of West Germany, this article asks: What is the impact of ear-wiring on social life? And, what new kinds of perception result from headphone listening? It traces how the use of earphones turned from being a static “technique of listening” into a mobile “technique of acoustic privatization.” Ultimately, this article interprets today's portable headphones as “head cocoons” that enable mobile listeners to actively carve out sonic privacy while on the move.

Trust and Sexual Interaction: The Significance of the Internet on the Sex life and Sexual Risk Behaviors Of Gay and Bisexual Men in Spain

ABSTRACT

This study provides an understanding of the significance of the use of the Internet to find sexual partners, its impact on sexual life, and how it is linked to unprotected sex among gay and bisexual men. A grounded approach was used to analyze interviews with 31 men (aged 19 to 46 years) from Madrid, Barcelona, and Bilbao/San Sebastián, Spain. The results reveal that the Internet is impacting the form and style of life of many men, and particularly their experience of sexuality. Many men regard their sexual experiences with casual partners met through the Internet as unsatisfactory or frustrating. The men provided several reasons behind the search for sexual partners via the Internet: Some interviewees sought to channel needs other than the sexual (company, affection, stable partner). Trust and assumptions built into the virtual interaction become a key to understanding why some men have unprotected sex with partners met on the Internet.     

Predictors of HIV Sexual Risk Behavior Among Men Who Have Sex with Men,Men Who Have Sex with Men and Women,and Transgender Women

ABSTRACT

Men who have sex with men, men who have sex with men and women, and transgender women are at high risk for HIV infection. This study seeks to clarify which known HIV risk factors (partner type, sex location, serodiscordance, multiple sex partners, substance use during sex) contribute to engagement in high-risk (unprotected receptive anal) sex in each population. Data collected from June 2005 through June 2008 indicate all three populations display different HIV sexual risk profiles. The data suggest that HIV-prevention interventions should be individually tailored to address the specific needs of these three highly vulnerable and impacted populations.     

Why Wait ‘til Marriage? The Determinants of Premarital Sex among Adolescents in a Country in Sub-Saharan Africa: Botswana

The purpose of the study was to describe the premarital sexual behaviors of Botswana adolescents and examine the factors associated with premarital sex intentions. An anonymous self-reported questionnaire was administered to 1,054 pupils ages 10 to 18 years in school and out of school. The findings indicate that the theory of planned behavior provides a model for developing interventions to reduce the risk behavior in regard to HIV/AIDS through premarital sex. The findings in the study indicate factors that influence adolescent intentions to engage in premarital sexual intercourse and the need to address these when designing effective interventions.     

Links between informal caregiving and volunteering in Sweden: a 17-year perspective

This article analyses informal caregiving and volunteering in organizations over 17 years in Sweden, with a focus on links between these two forms of unpaid activities. The discussion is based on results from a national survey that was repeated four times in the period 1992–2009. Links were found between the different types of activities. In all four studies a substantial group of the population was involved both in informal caregiving and volunteering. This group of ‘active citizens’ are commonly also engaged in informal social networks. This ‘double active’ group had increased over time and they provide a substantial amount of hours of involvement. Patterns outlined in this article demonstrate that unpaid activities represent a multifaceted phenomenon, and that the boundaries between informal caregiving and volunteering as forms of engagement may be more fluid than has previously been acknowledged. The results challenge the literature in which informal caregiving is viewed as a major obstacle to volunteering. At the same time, however, informal caregiving in general was found to be increasing. There might be reasons to be cautious about the possible risk that too much pressure on citizens for informal caregiving might jeopardize the type of double involvement that is outlined in this article.     

The Role of Hawaiian Elders in Substance Abuse Treatment Among Asian/Pacific Islander Women

SUMMARY

The elders of a culture are often the designated transmitters of long-standing values and ways that define the unique essence of a people. Küpuna (elders) teachings are especially important to Native Hawaiians who have experienced the cumulative effects of cultural imperialism, which has taken their lands, discouraged use of their language and cultural ways, damaged their identity as a people and destroyed their sovereignty.

Modern day cultural imperialism, which universalizes the dominant group's experience and culture, renders minority groups as invisible while marginalizing them (Young, 1990). The chronic stress of this insidious form of oppression can translate into physical, mental health problems which lead to decreased life expectancy (McEwen, 1998; Schulkin, Gold & McEwen, 1998). Statistics on Hawaiians and other Asian/Pacific Islanders in Hawaiì indicate these groups have high rates of health problems and increasing rates of substance abuse (Office of Hawaiian Affairs, 1998).

This article describes the roles and Hawaiian practices of küpuna who acted as facilitators in the healing of Asian/Pacific Islander pregnant and postpartum women who participated in a culturally based substance abuse treatment program (CBSATP). The findings of a qualitative study, which examined the effectiveness of küpuna in these roles and their implications for practice are discussed.     

The Social Life of Homelessness: Myths and Social Standing

There are two groups of people, the Insiders and the Outsiders. Insiders have access to a network of social transactions that enable them to tap into resources and information that lead to employment, housing, and other opportunities for upward mobility. These processes are often informal, and sometimes exclusive. The social networks that Outsiders have pertain largely to the acquisition of a meal or a night’s shelter. They do not have access to the better-endowed social networks of Insiders, and are therefore not privy to the informational and resources exchange that takes place therein. This translates into fewer job interviews, fewer housing applications, etc. Finally, this means that when an Outsider experiences a stressor (i.e., the flu, eviction, unemployment), it can take on crisis proportions leading ultimately to homelessness. However dim the prospects of Outsiders are, there are specific corrective processes, which can be implemented.     

Counseling Strategies with Gay and Lesbian Youth

Counseling needs of gay and lesbian youth have not been adequately researched. Identification of these issues has only been underway for adequately researched. Identification of these issues has only been underway for approximately ten years, as service providers and researchers turned their attention to this population. Factors, which contribute to a presenting clinical picture, include stigmatization, hiding and isolation, a sense of being different, lack of family support, harassment, and violence. Each of these areas is discussed, integrating case vignettes and research findings.
