Sex risk behaviors and substance use are intertwined. Many men continue to engage in high-risk sexual behaviors even when enrolled in substance use disorder (SUD) treatment. We hypothesized that changes in sex risk behaviors would coincide with changes in drug/alcohol use severity among men in SUD treatment. During an HIV risk-reduction trial, men in methadone maintenance and outpatient drug-free treatment (N = 359) completed assessments at baseline and six months after. We assessed changes in sex risk and substance use severity, using the Addiction Severity Index–Lite (ASI-Lite), controlling for treatment condition. In multinomial logistic regressions, decreased alcohol severity was significantly associated with decreases in reported sex partners, and increased alcohol severity was significantly associated with increases in reported sex partners. Increasing drug use severity was significantly associated with maintaining and initiating sex with a high-risk partner, while decreasing alcohol use severity was significantly associated with discontinuing sex under the influence. However, changes in drug/alcohol use severity were not associated with changes in unprotected sex. Substance use reductions may decrease HIV risk behaviors among male substance users. Our findings highlight the importance of integrating interventions in SUD treatment settings that address the intersection of sex risk behaviors and substance use.  相似文献

Pregnancy among adolescents/young adults continues at epidemic levels despite widespread concern regarding its social and psychological consequences. Cognitive psychologists point out that active decisions and behaviors such as those involved in effective contraception are facilitated or inhibited by any of a number of relevant attitudes and beliefs. The present investigation examined several such cognitive variables. Specifically, the following hypotheses were tested: Among adolescents/young adults, the use of effective contraception would be positively related to (a) the number of known cases of unwanted pregnancy of which subjects were directly aware, and (b) sexual guilt. A sample of 147 sexually active single college students aged 18–19 provided information relevant to these hypotheses. Analyses indicated that contraceptive behavior was unrelated to the number of unwanted pregnancies of which subjects were aware, but was substantially and significantly associated with sexual guilt, even when the possibility of pregnancy was precluded. The nature and implications of these findings are explored.  相似文献

A group's awareness of its own particular ‘identity (racial, cultural, ethnic, etc.) is heightened when it competes with other groups for power, privilege and resources. It is especially when a group (be it a dominant or subordinate group) perceives its culture threatened that it mobilizes its resources, articulates its beliefs and organizes its followers to assure its cultural survival. When its protective efforts are blocked or stymied, the group is transformed into what Smelser terms a ‘value‐oriented movement’. It becomes a culture under siege, and its development closely follows those characteristics and stages of collective behaviour that Smelser identifies. Continued stress or threats to a siege culture also lead to the transformation of the group's beliefs into what Rokeach identifies as a ‘closed belief system,’ characterized by dogmatic beliefs and, among its members, highly rigid and intolerant forms of behaviour. Where a group's racial beliefs are threatened, the group is readily transformed into a siege culture. This is evident especially in three historical/contemporary cases: White Southerners in the U.S., Afrikaners in South Africa, and White Rhodesians. Their cultural/racial beliefs (based on White superiority and White supremacy) threatened, the three groups became value‐oriented movements, their transformation and characteristics (closely paralleling each other) easily identified in terms of the analyses of Smelser and Rokeach.  相似文献

This study seeks to explore transnational communication among migrants of the Irish diaspora through an examination of the Orange Order's networks. It draws upon rare local and district records and press accounts to explain the migratory links and social worlds of Orange emigrants from Ulster. The substance of the study echoes the findings of Canadian historians who have much richer records than exist in the public domain in Britain. It demonstrates how Orangemen in Ireland came to recognise the diasporic dimension of their movement, and how members used the Order to negotiate some of the pathways of migration that were an important feature of their lives, and in the lives of the working class more generally. The essay generally seeks to demonstrate that the Orange Order acted as a network of friendship, camaraderie and support for emigrants and immigrants in the British World in the late nineteenth and early twentieth centuries.  相似文献

ABSTRACT

This article examines the working-class audience in Soviet Ukraine and the changes in its reading appetites during the 1920s. Under the Soviet nationalities policy of korenizatsiia introduced in 1923, the print-runs of Ukrainian-language literary products increased significantly. Nonetheless, as this article argues, those numerous publications often did not reach Ukrainian readers and if they did, they could hardly satisfy the interest appetites of an ever-growing Ukrainian audience. As the book reviews collected in the second half of the 1920s showed, the worker readers were interested in a certain type of literature – entertaining, easy to comprehend, dealing with contemporary issues and characters – that was not yet available in Ukrainian. Nevertheless, once that literature began to emerge in the late 1920s, the interest in contemporary books in Ukrainian increased. By examining every aspect of reading in Ukrainian – production, dissemination and consumption of the printed word – this article highlights the decisive role of Soviet readership in determining future official Soviet Ukrainian literature. The case of Soviet Ukraine emphasizes regional specifics and introduces an important language component to the Bolshevik reading revolution of the 1920s to early 1930s, largely ignored in the scholarship.  相似文献

Carpal tunnel syndrome (CTS) is a debilitating and expensive health problem. An inexpensive screening method that would differentiate between people who do not have CTS and those that may have CTS would be useful. The screening methodology investigated here had two phases: a structured interview and provocative vibrotactile testing (VT). The control group (n = 36) was composed of asymptomatic college students and faculty, the case group was composed of patients currently visiting an occupational medicine clinic for symptoms consistent with CTS. The case group was subdivided into positive and negative for nerve conduction latency, NCL+ (n = 21) and NCL- (n = 13), respectively. Using a scored, structured interview, 33 of the controls and none of the symptomatic cases were identified as non-CTS. The results from the provocative flexion VT indicated that if the difference between the age corrected baseline and the threshold at 15 minutes is 15 microm or more, the subject was likely to be NCL+ (odds ratio 12.6, 95% CI 3.8 to 41.8). Further research may improve this screening methodology to not only determine whether or not a person has CTS, but also to determine the level of median nerve impingement or damage.  相似文献

One of the major goals of family planning programs worldwide has been to reduce the level of fertility in hopes of slowing the rate of natural increase and promoting social and economic development. Such programs have now been in existence for sufficient lengths of time to have had an impact on fertility levels. In general countries with organized family planning programs, marked declines in fertility levels have been observed. The extent to which such declines may be credited to organized programs has not been rigorously measured because an appropriate research methodology has been lacking. This paper describes one method of directly linking declines in fertility levels to the contraceptive protection experienced by a population. The contribution of organized family planning programs is estimated by decomposing the amount of total contraceptive protection into within-program and outside-program sources.  相似文献

This article reports a survey of two statewide abortion related organizations: Missouri Citizens for Life and the Abortion Rights Alliance (N=524). The two groups differed signficantly on 12 of 18 Rokeach terminal values and on eight of 13 NORC instrumental values. Salvation was the value which most successfully differentiated the two groups. The two groups were used to establish the construct validity of 18 abortion attitude items. Members of the two groups also differed significantly on each of 18 beliefs, indicating that they tend not only to accept assertions made by their own group but also to reject assertions made by the other group. Anti-abortion were more likely than pro-abortion respondents to expect an increase in restrictions on abortion five years from now. Proabortion respondents attributed significantly more pro-abortion sentiment to U.S. adults than did the anti-abortion respondents.The cooperation of Maureen McCarthy, Ann O'Donnell and Kathy Edwards is gratefully acknowledged. This research project benefited greatly from the assistance of Mary Harbourt, Kathy Dunsford, Sherry Kilgore, Barbara Breen, Janice Warneke, Lynn Taylor, Janice Sato, Beth Wellman Granberg, Karen Quiring, and Patricia Shanks. Data collection was funded by a grant from the Graduate Research Council of the University of Missouri—Columbia. The analysis was funded by National Institute of Child Health and Human Development Grant No. 1-HD-82834. Tom Smith of the NORC at the University of Chicago provided the marginals on the abortion items from the 1980 General Social Survey.

Using the 1970 1/1,000 Public Use Sample of the U.S. population, the relationships of the closed and open birth intervals with parity and mother's age, with parity and marital duration, and with children ever born/marital duration and mother's age are analyzed. These findings both replicate and expand on Srinivasan's earlier research on the open interval. The open interval is more sensitive as an index of marital fertility when marital duration and parity are controlled than when mother's age and parity are controlled.  相似文献
