Partnered intimate activities in early adolescence: findings from the UK Millennium Cohort Study
Full text linkPurpose:
Little is known about potential influences on emerging partnered intimate behaviors in early adolescence. We investigate (1) the prevalence of partnered intimate activities and (2) associations with social relationships, parental monitoring and supervision, health behaviors, and psychosocial well-being.
Methods:
We used population-based data from the UK's Millennium Cohort Study on 11,079 participants aged 14 years. Partnered intimate activities were grouped into three categories: “light” (handholding, kissing, and cuddling); “moderate” (touching and fondling under clothes); and “heavy” (oral sex and sexual intercourse). Multinomial logistic regression models were used.
Results:
Thirty percent of study participants reported not engaging in partnered intimate activity. Fifty-eight percent reported “light,” 7.5 percent “moderate,” and 3.2 percent “heavy” activity. Associated with increased likelihood (adjusted relative risk ratios [RRRs]) of intimate activities were confiding worries in a friend (light RRR = 2.13, moderate RRR = 3.42, heavy RRR=5.32), low parental monitoring—staying out late or overnight (late: light RRR = 1.62, moderate RRR = 2.44, heavy RRR = 2.32; overnight: light RRR = 1.57, moderate RRR = 1.94, heavy RRR = 3.38), health-damaging behaviors (per unit increase: light RRR = 1.91, moderate RRR = 3.15, heavy RRR = 5.03), and depressive symptoms (per scale point increase light RRR = 1.03, moderate RRR = 1.09, heavy RRR = 1.11). Confiding in a parent was associated with lower likelihood of intimate activity (light RRR = .82, moderate RRR = .65, heavy RRR = .65).
Conclusions:
Partnered intimate activity of some form is commonplace among 14-year-olds in the United Kingdom. Given the short- and long-term implications of adolescent sexual development and well-being, improving our understanding of influences could help identify opportunities for interventions with benefits across the lifecourse
Prevalence of masturbation and associated factors in a British national probability survey
No full textA stratified probability sample survey of the British general population, aged 16 to 44 years, was conducted from 1999 to 2001 (N = 11,161) using face-to-face interviewing and computer-assisted self-interviewing. We used these data to estimate the population prevalence of masturbation, and to identify sociodemographic, sexual behavioral, and attitudinal factors associated with reporting this behavior. Seventy-three percent of men and 36.8% of women reported masturbating in the 4 weeks prior to interview (95% confidence interval 71.5%-74.4% and 35.4%-38.2%, respectively). A number of sociodemographic and behavioral factors were associated with reporting masturbation. Among both men and women, reporting masturbation increased with higher levels of education and social class and was more common among those reporting sexual function problems. For women, masturbation was more likely among those who reported more frequent vaginal sex in the last four weeks, a greater repertoire of sexual activity (such as reporting oral and anal sex), and more sexual partners in the last year. In contrast, the prevalence of masturbation was lower among men reporting more frequent vaginal sex. Both men and women reporting same-sex partner(s) were significantly more likely to report masturbation. Masturbation is a common sexual practice with significant variations in reporting between men and women
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
What factors are associated with reporting lacking interest in sex and how do these vary by gender? Findings from the third British national survey of sexual attitudes and lifestyles
Full text linkObjectives: To investigate factors associated with
reporting lacking interest in sex and how these vary by
gender.
Setting: British general population.
Design: Complex survey analyses of data collected
for a cross-sectional probability sample survey,
undertaken 2010–2012, specifically logistic regression
to calculate age-adjusted OR (AOR) to identify
associated factors.
Participants: 4839 men and 6669 women aged 16–74
years who reported ≥1 sexual partner (opposite-sex or
same-sex) in the past year for the third National Survey of
Sexual Attitudes and Lifestyles (Natsal-3).
Main outcome measure Lacking interest in sex for ≥3
months in the past year.
Results: Overall, 15.0% (13.9–16.2) of men and 34.2%
(32.8–35.5) of women reported lacking interest in sex.
This was associated with age and physical and mental
health for both men and women, including self-reported
general health and current depression. Lacking interest
in sex was more prevalent among men and women
reporting sexually transmitted infection diagnoses
(ever), non-volitional sex (ever) and holding sexual
attitudes related to normative expectations about sex.
Some gender similarities in associated relationship and
family-related factors were evident, including partner
having had sexual difficulties in the last year (men: AOR
1.41 (1.07–1.86); women: AOR 1.60 (1.32–1.94)), not
feeling emotionally close to partner during sex (men:
3.74 (1.76–7.93); women: 4.80 (2.99–7.69) and ease of
talking about sex (men: 1.53 (1.23–1.90);women: 2.06
(1.77–2.39)). Among women only, lack of interest in sex
was higher among those in a relationship of >1 year in
duration and those not sharing the same level of interest
(4.57 (3.87–5.38)) or preferences (2.91 (2.22–3.83))
with a partner.
Conclusions: Both gender similarities and differences
were found in factors associated with lacking interest
in sex, with the most marked differences in relation to
some relationship variables. Findings highlight the need to
assess, and if appropriate, treat lacking interest in sex in a
holistic and relationship-specific way
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
