Understanding the transfer of knowledge and skills from training to preventive action using ergonomic work analysis with 11 female VDT users

A qualitative evaluation of 11 VDT users, who participated in a training program for the prevention of musculoskeletal and visual problems, investigated the extent of the application of the taught principles in everyday work. Data were collected over a 2 to 3 day period for each trainee, through an ergonomic work analysis in situ and semi-structured interviews, followed by recommendations, when appropriate, corresponding to the taught principles. A case analysis and a cross analysis of the data provided information about the developed ability for self-analysis of work regarding posture and visual comfort and what influenced it. A model depicting the process of transfer of knowledge and skills, from the training program to preventive action, was abstracted from data analysis. This model allows both the identification of problems in applying taught principles and the means to readjust the training program.     

Notebook computer use with different monitor tilt angle: effects on posture, muscle activity and discomfort of neck pain users

This study aimed to evaluate the posture, muscle activities, and self reported discomforts of neck pain notebook computer users on three monitor tilt conditions: 100°, 115°, and 130°. Six subjects were recruited in this study to completed typing tasks. Results showed subjects have a trend to show the forward head posture in the condition that monitor was set at 100°, and the significant less neck and shoulder discomfort were noted in the condition that monitor was set at 130°. These result suggested neck pain notebook user to set their monitor tilt angle at 130°.     

Adolescents' beliefs about marijuana use: a comparison of regular users, past users and never/occasional users

A questionnaire investigating adolescents' opinions and experiences regarding marijuana use was administered to 163 adolescents and young adults (96 boys and 67 girls) aged 13 to 20 (mean age = 16.8, s.d. = 1.5). Items referred to marijuana and other substances' dangerousness, representations regarding the positive and negative consequences of marijuana use. Responses were compared according to marijuana use status (classified into never/occasional use, current regular use and past regular use). Results show that adolescents' opinions differ according to their experience with marijuana use. Current regular users evaluate marijuana as less dangerous, but alcohol and heroin as more dangerous in comparison with never/occasional and past users. Current and past users are more likely to define marijuana as a medical drug and a plant used in agriculture, and less likely to define it as an illegal drug. Current and past users evaluate marijuana use as a way to cope with stress, to relax to a greater extent than do never/occasional users do. The latter attribute more negative consequences to marijuana use such as diminished driving ability and school performance and a pathway to hard drugs.     

Sexual decision making and safer sex behavior among young female injection drug users and female partners of IDUs

Data from interviews with 94 young women who were injection drug users (IDUs) or partners of IDUs were analyzed to examine associations between self-reported sexual decision making and condom use, contraceptive use, and relationship characteristics. Most women (73-85%) reported participating in decisions about condom use, contraception, and when to have sex. Adjusting for potential covariates, respondents who reported participating in decisions about condom use and when to have sex were 7 and 19 times, respectively, more likely than others to report recently using condoms. Respondents who reported participating in decisions about contraception were 20 times more likely than others to report recently using contraceptives. Longer sexual relationships were associated with decreased likelihood of condom or contraceptive use.     

The connection between working hours and body mass index in the U.S.: a time use analysis

Over recent decades, Americans have transitioned from working in active jobs to working in sedentary jobs, and there have been dramatic increases in hours worked for certain demographic groups. While a body of research documents that time spent working is associated with increased body mass index (BMI), this paper explores possible mechanisms for that relationship using time use data. This paper finds that, for workers in non-strenuous jobs, 10 additional hours spent working are associated with an increase in BMI of 0.424 for women and 0.197 for men, representing an increase of 2.5 and 1.4 pounds, respectively. The paper does not find a relationship between working time and BMI for workers in strenuous jobs. For workers in non-strenuous jobs, the effect of time spent working on BMI becomes smaller after accounting for time spent sleeping for both men and women and time spent in exercise and food preparation for women only; the effect becomes larger after accounting for screen time for both men and women and time spent in secondary eating and commuting for women only. Screen time is the single time use channel associated with the largest differences in the estimated effect of time spent working on BMI for both women and men employed in non-strenuous jobs. After controlling for all time use channels, the effect of hours worked on BMI decreases for women, but increases for men. These findings suggest plausible mechanisms for the association between time spent working and obesity.     

The effect of Video Display Terminal (VDT) mouse use on muscle contractions in the neck and forearm

This study used surface electromyography (EMG) to examine the percent of maximum voluntary contraction (%MVC) of the upper trapezius, the flexors of the wrist/fingers and extensors of the wrist/fingers during Video Display Terminal (VDT) mouse use with the mouse positioned either next to the computer or on a lapdesk. Thirty participants, between the ages of 18 and 40, used a VDT mouse to follow a prescribed pattern for three trials at each location. Although there was a trend towards the lapdesk location producing lower %MVC than the computer location for the trapezius and wrist/finger flexors (lapdesk: trapezius M 4.71%, wrist/finger flexors M 3.53%; computer: trapezius M 5.74%, wrist/finger flexors M 3.94%) a two way ANOVA controlling for sequence and order found no significant difference between the means. There was no trend for the effects of location for the wrist/finger extensors. These results suggest that changing the position of the mouse may not significantly reduce muscle contractions.     

An overview of current clinical issues in separation and placement

This article reviews a wide range of literature and the knowledge base that is necessary for effective treatment of children in foster and adoptive homes. The pitfalls in clinical work with placed children are identified. In addition to the psychological effects of placement on children, there is review of knowledge affecting both foster and adoptive parents. Treatment approaches and tools that are presented in the literature are summarized.     

What can we learn about the female condom online? An analysis of visual representations of the female condom on the Internet

This study used social functional semiotics and the concept of gender display to examine visual representations of the female condom on Google Images. A content analysis of 195 web images identified that almost half of the images were about the appearance theme of the female condom followed by the how-to-use theme. A majority of visuals did not have captions. Humans were present in 64.1% of the images, with a majority of visuals depicting dismembered female body parts rather than a whole person. These and other findings are discussed in regards to theoretical and health message design implications.     

Drug use,prostitution and the prevalence of AIDS: An analysis using census tracts

This paper reports on preliminary efforts to study at the census tract level the reciprocal relationships between AIDS and street crime, particularly prostitution and drug offenses and the prevalence of AIDS. The Los Angeles County Department of Public Health provided the number of reported AIDS cases by census tract. The data on reported crimes and arrests, organized by reporting districts, came primarily from the Los Angeles County Sheriff's Department and the Los Angeles City Police Department. Although this strategy needs replication and extension, the present findings suggest that sexual orientation, drug use and prostitution are useful risk variables at the census track level.     

An analysis of the encoding and decoding of spontaneous and posed smiles: The use of facial electromyography

Twenty subjects judged 80 video segments containing brief episodes of smiling behavior for expression intensity and happiness of the stimulus person. The video records were produced under instructions to (a) pose, (b) experience a happy feeling or (c) to both experience and show a happy feeling. An analysis of the integrated facial electromyogram (EMG), recorded over four muscle regions (zygomaticus major, depressor anguli oris, corrugator supercilii, andmasseter), showed that judgments of happiness and of intensity of expression could be predicted in a multiple regression analysis (multipleR = .64 for perceived happiness and .79 for perceived expression intensity). The perception of happiness was affected by EMG activity in regions other thanzygomaticus major. The use of parameters other than the mean of the integrated EMG, namely variance, skewness, kurtosis and properties of the amplitude distributions across time, provided accurate classification of the elicitation conditions (pose happiness versus experience happiness) in a discriminant analysis. For the discrimination of posed and felt smiles variables describing aspects of facial activity in the temporal domain were more useful than any of the other measures. It is suggested that facial EMG can be a useful tool in the analysis of both the encoding and decoding of expressive behavior. The results indicate the advantage of using multiple-site EMG recordings as well as of using amplitude and temporal characteristics of the facial EMG measures.The research was supported in part by funds associated with the John Sloan Dickey Third Century Professorship (Kleck) and in part by grant BNS-8507600 from the National Science Foundation (Lanzetta). Ursula Hess and Arvid Kappas were supported by stipends from the Deutscher Akademischer Austauschdienst (German Academic Exchange Service).     

The use and abuse of female domestic workers from Sri Lanka in Lebanon

Women who migrate from Sri Lanka to become domestic workers in Lebanon face gender, class, and race discrimination that often results in abuse, yet the predicament of these women is largely ignored by local and international humanitarian and human rights agencies. Public consciousness about the plight of Asian domestic workers in the Persian Gulf region was raised in 1990 when domestic workers were repatriated in the wake of the Gulf War. In Lebanon, nearly half of the work permits granted to foreigners in 1997 were to women from Sri Lanka. This migration began in the 1970s and is sanctioned by the Sri Lanka government because of the economic benefits accruing from wages sent home by these women. Lebanese families procure domestic positions through an employment agency that arranges transportation and entry for the Sri Lankan women. These women, especially minors, often have to bribe Sri Lankan government agents to falsify travel documents. Upon arrival in Lebanon, the women have no support systems or job security. Most employment contracts last 3 years and pay $100/month with no benefits or protection from local labor laws. Domestic workers are made vulnerable by employers who withhold salaries or travel documents. Upon return to Sri Lanka, former domestic workers face social disapproval and marital problems. To redress this situation, the governments of sending and receiving countries must take action to protect female migrant workers, and nongovernmental organizations must publicize the plight of these women and take action to address the abuses they face.     

Foster carer stress and satisfaction: An investigation of organisational,psychological and placement factors

The unique demands of the foster carer role are associated with high levels of self-reported stress among foster carers. The current study examines the amount of carer stress that can be attributed to certain role specific challenges and how stress from these challenges varies between carers and placements. As a secondary aim the study examines carer perceptions on current organisational support and training. Participants were sourced from a national fostering agency with branches in the local area. Carers were eligible to participate in the study if they were caring full time for at least one foster child. Eligible carers completed an identical online or paper survey including measures of general stress and parenting stress as well as study specific measures regarding satisfaction with organisational training and support. Results demonstrated that challenging behaviours are the most stressful unique role demand for foster carers and the largest predictor of carer stress levels. Overwhelmingly carers reported a desire for additional training in order to support them in their role. The results support previous research outlining the difficulties faced by foster carers and the need to improve support and training to ensure good placement outcomes including placement stability and reduced carer attrition.     

Sibling birth order,use of statutory measures and patterns of placement for children in public care: Implications for international child protection systems and research

Public care of abused and neglected children is one important element of statutory intervention which aims to address the major global challenge of protecting children from abuse and neglect. Where a child is part of a sibling group, this introduces particular challenges with regard to meeting the needs of all those affected. This paper presents findings from one of the first studies examining birth order effects on statutory intervention patterns for looked-after siblings. The experiences and outcomes of children were compared depending on maternal birth order at the time of data collection. We found strong evidence that the length of time from first referral of a child deemed at risk to first statutory intervention is greater for first-born than for last-born children and first-born children are significantly older than last-born children when they are first placed on statutory measures. The study concludes that first-born siblings may be particularly vulnerable to delayed statutory intervention and the cumulative effects of harm and certain routes to permanence may be less available to them. We argue for increased focus within international child welfare policy and practice on timely and intensive assessment of first-born children, where risk of maltreatment is identified, in order to address potential inequalities of access to protection. A focus on risk introduced by systemic factors within legal and welfare systems in addition to risk introduced by perpetrators of abuse is needed. We also argue for greater research attention to, and more precise measurement of, birth order as a variable in studies of the looked-after population.     

Socioeconomic status and health: a micro-level analysis of exposure and vulnerability to daily stressors

This study examines the interconnections among education--as a proxy for socioeconomic status--stress, and physical and mental healthy by specifying differential exposure and vulnerability models using data from The National Study of Daily Experiences (N = 1,031). These daily diary data allowed assessment of the social distribution of a qualitatively different type of stressor than has previously been examined in sociological stress research--daily stressors, or hassles. Moreover, these data allowed a less biased assessment of stress exposure and a more micro-level examination of the connections between stress and healthy by socioeconomic status. Consistent with the broad literature describing socioeconomic inequalities in physical and mental health, the results of this study indicated that, on any given day, better-educated adults reported fewer physical symptoms and less psychological distress. Although better educated individuals reported more daily stressors, stressors reported by those with less education were more severe. Finally, neither exposure nor vulnerability explained socioeconomic differentials in daily health, but the results clearly indicate that the stressor-health association cannot be considered independent of socioeconomic status.     

Racial and ethnic differences in patterns of adolescent tobacco users: A latent class analysis

BackgroundLittle is known about how tobacco use varies among youth of different racial and ethnic groups and how these patterns are related to levels of nicotine dependence.ObjectivesThis study investigated the tobacco use patterns of White, African American, and Hispanic high school students. We further explored whether tobacco use patterns were associated with levels of nicotine dependence and gender.MethodsData were analyzed from the 2014 National Youth Tobacco Survey (NYTS) of high school students who endorsed at least one form of tobacco use in their lifetime (n = 4691). Three separate latent class analysis (LCA) models were estimated using seven different types of tobacco products as indicators. Also, the level of nicotine dependence was compared with one class to another class in three racial/ethnicity groups.ResultsFour classes of White youth were identified: (1) “Non-user” (67%), (2) “Polytobacco” (6%), (3) “Chewing Tobacco” (8%), and (4) “(E-)Cigarettes” (19%) classes. The “Polytobacco” class had the highest nicotine dependence followed by “Chewing Tobacco,” “(E-)cigarettes,” and “Non-user.” Among African American youth, two tobacco patterns were identified: “Non-user” (91%) and “Cigarette/Cigar” (9%). The “Cigarette/Cigar” class had greater nicotine dependence than the “Non-user” class. Among Hispanic youth, three subgroups were identified: “Non-user” (78%), “(E-)Cigarette/Cigar” (14%), and “Hookah” (18%). “(E)Cigarette/cigar” had the highest nicotine dependence in Hispanic youth followed by the “Hookah” and “Non-users” classes.ConclusionWe found distinct classes of youth tobacco use by race/ethnicity. Although poly-tobacco use was common, White, African American, and Latino youth used different tobacco types, suggesting that racially and ethnically targeted prevention strategies may be indicated.
