Abstract

Objective: To examine the health literacy of college students. Participants: A convenience sample of 245 graduate and undergraduate college students. Methods: During February–April of 2018 participants completed the Short Test of Functional Health Literacy which assessed literacy on two passages describing a thyroid scan, and basic healthcare insurance information. Results: Most college students displayed adequate health literacy (99.2%). The ANOVA analyses revealed college classification was the most significant predictor, followed by ethnicity, sex, and primary language. Age was significantly related to health literacy, when holding college classification constant. Interestingly, college major, healthcare work experience, or having health care credentials were not predictors of health literacy. Conclusion: This group of college students had adequate health literacy skills. However, the results of this study revealed demographic disparities that suggest further study.  相似文献

Skinner (1957) differentiated the roles of the speaker and the listener in a verbal encounter. Although not extensively emphasized, Skinner suggested an individual often behaves verbally even when responding as a listener. Children diagnosed with autism spectrum disorders (ASD) often display the absence of important, and basic verbal repertoires that limit their ability to engage in a variety of social skills or problem-solving skills. Joint control suggests that multiply controlled verbal responding involves functional control of two 2 or more stimuli or verbal operants. This systematic literature review provides a summary of publications specifying the relation and implications of the analysis of joint control and joint control training in the acquisition of multiply controlled, non-speaker behaviors (e.g., selection-based behavior; , sequencing behavior). The synthesis suggests that joint control training presents as a promising analytic tool in guiding interventions to teach complex, multiply controlled verbal and non-verbal repertoires to children diagnosed with autism ASD and/or other developmental disabilities. Recommendations for future research in joint control, as well as the implementation of joint control training, are provided.

ABSTRACT

The shift in the technology landscape has altered the technology ecosystem of adolescents and emerging adults in the 21st century. Yet, with greater use of digital gadgets comes greater mental health risks that technological advancement brings. This study provides a narrative review of contemporary cyber risks faced by adolescents and emerging adults. In particular, this review will cover dangers and effects of cyber-bullying, social media, cyber-dating violence, sextortion, sexting, revenge porn, online dating, catfishing, and scammers, with an emphasis to raise awareness and encourage proactive efforts dedicated to address these social concerns as the digital era continues to evolve.  相似文献

Problem

There is lack of data on the rate of episiotomy in Lebanon and the study’s hospital.

Background

Only a few studies have addressed episiotomy practice in Lebanon and the Middle East and they show varying rates.

Aim

To identify the rate, and change in rate, of episiotomy practice over the years at a teaching hospital in Lebanon and to assess whether maternal age, parity, fetal weight, woman’s hospital admission class, and physician’s gender were associated with episiotomy. We also tested the association between episiotomy and postpartum hemorrhage and/or high degree perineal tears.

Methods

A retrospective observational study was conducted on 1756 records for women having a normal vaginal birth at a single centre from January 2009 to January 2014.

Findings

The rate of episiotomy at the hospital was very high, with 97.4% of women receiving an episiotomy in 2009. A major decrease in the rate was identified with a decline from 97.4% in 2009 to 73.3% in January 2014. Episiotomy was found to be associated with parity, maternal age, and with high degree perineal tears.

Discussion

The episiotomy rate at this centre remains higher than the 10% rate recommended by the World Health Organization, although there has been a significant reduction after a call for restrictive rather than liberal use.

Conclusion

Raising awareness among providers appeared to play a significant role in reducing this rate, although more efforts remain warranted. Other strategies – such as raising awareness of women about potential risks of episiotomy – are also worth exploring.  相似文献

ABSTRACT

There is a substantial literature on how to deliver feedback to change performance. However, to date no research has been conducted on teaching employees how to effectively receive feedback, even though employee behavior during a feedback session could moderate the effects of feedback. Thus, we developed a list of skills that should be exhibited by an employee while receiving verbal feedback. We then evaluated their acquisition after behavioral skills training using a nonconcurrent multiple-baseline design across participants. The results showed that participants were able to acquire and maintain appropriate feedback receiving behavior.  相似文献

ABSTRACT

This paper analyzes the disjunctive temporalities of Occupy Philadelphia’s political constituencies. Drawing on both an ethnographic participant observation study of the Occupy Philadelphia movement and Philadelphia’s neoanarchist political communities, and on recent social scientific theorization of events, the paper argues that contradictory ideas about temporal timescales, momentum, duration, sequences, and rhythms of tactical and strategic action problematized interaction and coordination among movement participants. These points of coordinative disjuncture can be traced back to differences in participants’ ideas about prefigurative politics and strategic temporalities. Limning the temporal expectations and experiences of social movement participants, this paper contributes to the examination of both linkages and disjunctures between eventful temporalities experienced in moments of protest and in social movements with diverse timescales.  相似文献

ABSTRACT

This paper is about the changing imaginations of social work in an increasingly entangled world. It is also about the ways in which literatures shared across time and space encourage us to identify with larger collectivities. My central argument is that if social work is to find a larger vision in the wake of the failure of a range of modern progress narratives, we must engage differently with the challenge posed by multiplying and sometimes conflicting knowledge communities. Thinking with contemporary debates in transdisciplinary critical social theory, I nominate and explore a number of alternative heuristics—‘generational problematic,’ ‘translational space,’ and ‘imagined communities’—in support of future work on the uneven temporal and spatial communities of affiliation that reproduce and change what social work is, or could be, about. I conclude with theoretical suggestions, and some thoughts toward how social work education might better support incoming generations to locate themselves within the broader life-course of the discipline and profession.  相似文献
