Salient selves in uncertain futures

We examined possible selves during three distinct periods of uncertainty. Cancer survivors (Study 1a) and survivors’ romantic partners (Study 1b) rated the salience of possible selves in which the cancer did (negative possible self; NPS) and did not (positive possible self; PPS) return. Study 2 mapped PPS and NPS salience throughout the four-month wait for bar exam results. Study 3 experimentally primed possible selves among participants awaiting medical test results. PPS salience correlated positively, and NPS negatively, with indicators of health and well-being, and inducing focus on one’s NPS led to greater negative emotion and worry compared to a PPS induction, but not less positive emotion. These results illustrate the well-being implications of possible selves during periods of uncertainty

A perspective on studying electronic structure of batteries through soft X-ray spectroscopy

Understanding electronic structure is crucial to enhance the battery performance. Soft X-ray spectroscopy (SXS) is one of the most effective methods to provide direct probe of electronic states. Here, spectroscopic measurements of transition metal 3d and oxygen 2p states are simply reviewed. Then, we mainly focus on the perspective of the development direction of modern SXS techniques. Although the true power of recently developed high efficiency mapping of resonant inelastic X-ray scattering (mRIXS) has been apparent for materials and chemistry studies, great challenges remain for mRIXS spectroscopic interpretation, and the understanding of the battery materials on novel redox activities remains elusive

THE CHARACTERISTICS OF ENGLISH ADVERTISEMENTS CREATED BY STUDENTS OF BUSINESS ENGLISH CLASS AT PGRI UNIVERSITY SEMARANG. LEMBAGA PENELITIAN DAN PENGABDIAN PADA MASYARAKAT, UNIVERSITAS PGRI SEMARANG

This study investigates the characteristics of English advertisements created by the students of Business English Class at the University of PGRI Semarang. There were 25 students taken as the sample since they had been trained how to analyse and make English advertisement. At the end of the training session, 60 pictures of educational, tourism, and health products were distributed and the students were asked to create their own advertisement under each picture. There were only 30advertisement texts eligible for further analysis. The analysis was done to its lexical aspects, syntactical features as well as its rhetorical devices. The results show that most of the students were able to make their own advertisement texts but most of the words are verb and noun (90%), simple sentence (93%), and only 2 out of 30 advertisement (6.6%) used rhetorical devices. They need more time to practice writing informative and attractive advertisement text. Thus, for the next class session, it is recommended that the lesson materials in the Business English shouldbe divided into two mainstreams: Business Writing and Business Advertisement and each mainstream should be taught for 7 class sessions. By having such division, the students will have an ample time to do some advertisement-text practices

Does it fit okay? Problems with condom use as a function of self-reported poor fit

This is an open access article - Copyright © 2010 by the BMJ Publishing Group Ltd. All rights reservedOBJECTIVE: To identify associations between men's self-reports of ill-fitting condoms and selected condom use problems, using an event-specific analysis. METHODS: A convenience sample of men was recruited via advertisements in newspapers (two urban and one small town) and a blog on the website of a condom sales company. Men completed a questionnaire posted on the website of The Kinsey Institute for Research in Sex, Gender, and Reproduction. Inclusion criteria were: at least 18 years old, used condoms for penile–vaginal intercourse in the past 3 months and the ability to read English. RESULTS: In controlled, event-specific, analyses of 436 men, those reporting ill-fitting condoms (44.7%) were significantly more likely to report breakage (adjusted odds ratio (AOR 2.6), slippage (AOR 2.7), difficulty reaching orgasm, both for their female partners (AOR 1.9) and for themselves (AOR 2.3). In addition, they were more likely to report irritation of the penis (AOR 5.0) and reduced sexual pleasure, both for their female partner (AOR 1.6) and for themselves (AOR 2.4). Furthermore, they were more likely to report that condoms interfered with erection (AOR 2.0), caused erection loss (AOR 2.3), or became dry during sex (AOR 1.9). Finally, they were more likely to report removing condoms before penile–vaginal sex ended (AOR 2.0). CONCLUSIONS: Men and their female sex partners may benefit from public health efforts designed to promote the improved fit of condoms.Support for this project was provided, in part, by the Rural Center for AIDS/STD Prevention, a joint project of Indiana University, University of Colorado, and the University of Kentucky and by The Kinsey Institute for Research in Sex, Gender, and Reproduction, Indiana University

Is phosphodiesterase type 5 inhibitor use associated with condom breakage?

This is an open access article - Copyright © 2009 by the BMJ Publishing Group Ltd. All rights reserved.We tested the hypothesis that phosphodiesterase type 5 inhibitor (PDE5i) use would be associated with increased likelihood of condom breakage using an event-specific analysis. A convenience sample of 440 men completed an internetbased questionnaire that assessed variables pertaining to the last time they used condoms for penile-vaginal intercourse (PVI). A bivariate (screening) analysis was performed to identify covariates for a multivariate analysis using logistic regression. Altogether, 5.9% of the men reported breakage and 9.5% reported PDE5i use during the last time a condom was used for PVI. Among men who had used PDE5i during the last condom-protected occasion of PVI, 11.9% reported breakage compared with 5.3% of those not reporting PDE5i use. Adjusting for men’s age, ethnic minority status, marital status, reported duration of PVI and alcohol use at last PVI, those using PDE5i were about four times more likely to also report condom breakage (AOR 4.02; 95% CI 1.20 to 13.48; p=0.04). Of note, duration of PVI was independently associated with breakage (AOR 1.36; CI 1.02 to 1.83; p=0.04). Findings suggest that PDE5i use may potentially be associated with increased odds of condom breakage among some men.Support for this project was provided, in part, by the Rural Center for AIDS/ STD Prevention, a joint project of Indiana University, University of Colorado and the University of Kentucky, and by The Kinsey Institute, Indiana University

If the condom fits, wear it: a qualitative study of young African-American men

This is an open access article - Copyright @ 2004 BMJ Publishing GroupObjective: To extend the current knowledge base pertaining to condom failure among young African-American men by assessing their experiences with male condom use. Methods: Qualitative assessments were conducted with 19 African-American men (aged 18–29 years) who had just been diagnosed with an STI and reported using condoms in the previous 3 months. Results: Five categories were identified from the data. These categories pertained to: (1) the “fit and feel” of condoms; (2) condom brand and size; (3) application problems; (4) availability of condoms and lubricants; and (5) commitment to condom use. Common themes included reasons why men believed condoms would break or slip off during sex. Comfort problems, including tightly fitting condoms and condoms drying out during intercourse, were mentioned frequently. Condom associated erection problems were often described. Many men also noted that condom use reduced the level of sexual satisfaction for their female partners. Men noted that finding the right kind of condom was not always easy and it became apparent during the interviews that men typically did not acquire lubrication to add to condoms. Despite their expressed problems with using condoms, men were, none the less, typically emphatic that condom use is an important part of their protective behaviour against STIs. Conclusion: Men were highly motivated to use condoms; however, they experienced a broad range of problems with condom use. With the exception of losing the sensation of skin to skin contact, the vast majority of these problems may be amenable to behavioural interventions.This study was funded by a grant from the National Institutes of Mental Health (1 R21 MH066682-01A1)

Beyond 2D-grids: a dependence maximization view on image browsing

Ideally, one would like to perform image search using an intuitive and friendly approach. Many existing image search engines, however, present users with sets of images arranged in some default order on the screen, typically the relevance to a query, only. While this certainly has its advantages, arguably, a more flexible and intuitive way would be to sort images into arbitrary structures such as grids, hierarchies, or spheres so that images that are visually or semantically alike are placed together. This paper focuses on designing such a navigation system for image browsers. This is a challenging task because arbitrary layout structure makes it difficult -- if not impossible -- to compute cross-similarities between images and structure coordinates, the main ingredient of traditional layouting approaches. For this reason, we resort to a recently developed machine learning technique: kernelized sorting. It is a general technique for matching pairs of objects from different domains without requiring cross-domain similarity measures and hence elegantly allows sorting images into arbitrary structures. Moreover, we extend it so that some images can be preselected for instance forming the tip of the hierarchy allowing to subsequently navigate through the search results in the lower levels in an intuitive way
