Investigation of the computer experiences and attitudes of pre-service mathematics teachers: new evidence from Turkey

This study aimed to investigate the experiences of pre-service mathematics (PSM) teachers with computers and their attitudes toward them. The Computer Attitude Scale, Computer Competency Survey, and Computer Use Information Form were administered to 180 Turkish PSM teachers. Results revealed that most PSM teachers used computers at home and at Internet cafes, and that their competency was generally intermediate and upper level. The study concludes that PSM teachers' attitudes about computers differ according to their years of study, computer ownership, level of computer competency, frequency of computer use, computer experience, and whether they had attended a computer-aided instruction course. However, computer attitudes were not affected by gender.     

Internet access and use among homeless and indigent drug users in Long Beach, California.

There has been a growing interest in using the Internet to access a variety of populations for prevention education and health care. It is not clear that this is viable for homeless and other marginalized populations. The purpose of this study was to describe Internet access and use among a sample of homeless and indigent drug users. A brief questionnaire was developed to assess computer ownership, use, email, and Internet access and use. Participants were recruited through a community-based human immunodeficiency virus (HIV) prevention program. 265 participants completed the questionnaire. While 55% had ever used a computer in their lifetime, only 25% had ever owned a computer, 24% had ever had their own email account, 33% had access to a working computer in the last 30 days, 10% had sent or received email in the last 30 days, and 19% had surfed or accessed information on the Internet in the last 30 days. Logistic regression predicting lifetime use of a computer showed predictive factors of having completed high school (Odds Ratio [OR] = 4.5; 95% Confidence Interval [CI] = 2.41, 8.38) and number of days used amphetamines in the last 30 days, per 5 days of use (OR = 1.64; 95% CI = 1.18, 2.27). Inversely related were age, per 5 years of age (OR = 0.78; 95% CI = 0.65, 0.93) and number of days used marijuana in the last 30 days, per 5 days of use (OR = 0.97; 95% CI = 0.76, 0.99). Very low access and usage suggest that Internet-based public health education models be reexamined for this population. The association with amphetamine use may indicate a facilitating effect of amphetamine by heightening awareness and increasing wakefulness.     

Internet use and attitudes towards illicit internet use behavior in a sample of Russian college students.

This study assessed Internet use and attitudes toward illicit use of the Internet in a sample of Russian college students. A sample comprised of 198 students was recruited from a university in Moscow. Each participant completed a survey assessing demographic characteristics, Internet use, and attitudes towards engaging in illicit behaviors over the Internet. About half of the students reported that they used the Internet at least several times a year, with 8% reporting daily use of the Internet. Among Internet users, most reported having Internet access either at home or at a friends' home, and 16 % reported having Internet access from work, school, or a computer center. Among Internet users, the main purpose was for school-related activities (60%), followed by e-mail (55%), entertainment (50%), chatting (24%), and searching for pornography (6%). Although most students thought it was inappropriate to read someone else's e-mail, use someone else's password or credit card information without their permission, or break into someone's computer, many students did endorse those illicit behaviors. Over a fifth of the students reported that they knew hackers. Forty three percent of students agreed that people make too much fuss about watching videos, movies or downloading music on the Internet without paying. Males were more likely than females to report using the Internet for entertainment purposes (p = 0.006) and were more likely to agree that it was okay to break into someone's computer (p = 0.04). The results of this study suggest that these Russian college students predominately use the Internet to help with their schoolwork, to communicate with others, and for entertainment. These results also suggest that interventions may be useful to change attitudes endorsing illicit uses of the Internet.     

Internet accessibility and usage among urban adolescents in Southern California: implications for web-based health research.

The World Wide Web (WWW) poses a distinct capability to offer interventions tailored to the individual's characteristics. To fine tune the tailoring process, studies are needed to explore how Internet accessibility and usage are related to demographic, psychosocial, behavioral, and other health related characteristics. This study was based on a cross-sectional survey conducted on 2373 7th grade students of various ethnic groups in Southern California. Measures of Internet use included Internet use at school or at home, Email use, chat-room use, and Internet favoring. Logistic regressions were conducted to assess the associations between Internet uses with selected demographic, psychosocial, behavioral variables and self-reported health statuses. The proportion of students who could access the Internet at school or home was 90% and 40%, separately. Nearly all (99%) of the respondents could access the Internet either at school or at home. Higher SES and Asian ethnicity were associated with higher internet use. Among those who could access the Internet and after adjusting for the selected demographic and psychosocial variables, depression was positively related with chat-room use and using the Internet longer than 1 hour per day at home, and hostility was positively related with Internet favoring (All ORs = 1.2 for +1 STD, p < 0.05). Less parental monitoring and more unsupervised time were positively related to email use, chat-room use, and at home Internet use (ORs for +1 STD ranged from 1.2 to 2.0, all p < 0.05), but not related to at school Internet use. Substance use was positively related to email use, chat-room use, and at home Internet use (OR for "used" vs. "not used" ranged from 1.2 to 4.0, p < 0.05). Self-reported health problems were associated with higher levels of Internet use at home but lower levels of Internet use at school. More physical activity was related to more email use (OR = 1.3 for +1 STD), chat room use (OR = 1.2 for +1 STD), and at school ever Internet use (OR = 1.2 for +1 STD, all p < 0.05). Body mass index was not related to any of the Internet use-related measures. In this ethnically diverse sample of Southern California 7(th) grade students, 99% could access the Internet at school and/or at home. This suggests that the Internet is already a potential venue for large scale health communication studies. Adolescents with more psychosocial risk factors or detrimental health behaviors were more likely to use the Internet. Therefore, if used properly, Internet interventions could effectively address the high risk populations. Additional research is needed to gain a more complete understanding of the positive and negative consequences of Internet use among adolescents.     

Technological advancements and Internet sexuality: does private access to the Internet influence online sexual behavior?

The aim of this study was to investigate whether demographic characteristics and sexual behavior online and offline were associated with private, respectively, nonprivate access to the Internet in a Web sample of people who use the Internet for sexual purposes. A total of 1,913 respondents completed an online questionnaire about Internet sexuality, and 1,614 reported using the Internet for sexual purposes. The majority of these respondents reported having access to an Internet-connected computer no one else had access to (62 percent women and 70 percent men). The results showed that it is possible to differentiate between those who have access to an Internet-connected computer no one else has access to and those who have shared access to an Internet-connected computer. Not only did they differ in demographic characteristics, but also in the sexual activities they engaged in on the Internet. Different patterns were found for women and men. For example, men who had private access to Internet-connected computers were more likely than those who had shared access to seek information about sexual issues. Thus, having access to Internet computers no one else has access to may promote sexual knowledge and health for men. The results of this study along with the technological development implies that in future research, attention should be paid to where and how people access the Internet in relation to online behavior in general and online sexual behavior in particular.     

Social Interaction During Computer-based Activities: Comparisons by Number of Sessions, Gender, School-level, Gender Composition of the Group, and Computer-child Ratio

This study assessed the quality of social interactions that occur in group-based computer learning contexts. Gender comparisons of interactions were examined across 3 sessions with 116 preschoolers (M age?=?4.9 years) and 108 fifth and sixth-grade (M age?=?11.7 years) Canadian children from southwestern Ontario, when children had access to one computer per child (parallel computer) or one computer per group (integrated computer), and when they worked with same-gender or mixed-gender peers. Preschoolers engaged in more collaborative behaviors in mixed-gender than same-gender groups, while elementary children engaged in collaborative behaviors more often in integrated than parallel computer conditions. In mixed-gender groups, boys were more likely than girls to dominate the computer in elementary school while girls were more likely than boys to dominate the computer in preschool.     

我国运动员退役意识与心理状态的定量分析

基于运动员退役过程理论,对我国运动员的退役意识和生活心理状态进行定量分析,旨在探索运动员在退役过程中的意识与心理状态变化。通过对789名运动员（现役运动员540人,退役运动员249人）的退役意识和生活心理状态调查,结果发现运动员的退役意识主要反映在运动员角色和退役准备的认知方面,当运动员角色的认知下降时,退役准备的认知会上升;在生活心理状态的评估方面,有退役想法的运动员要比无退役想法的运动员差;现役运动员的心理状态与退役运动员的心理状态在表现形式上不一样,主要表现为现役运动员反映了较高的生活焦虑,而退役运动员反映了较高的孤独感;分析进一步发现,运动员在退役过程中普遍感到缺乏社会支持。基于以上这些发现,研究从社会心理学角度,讨论了我国运动员退役的意识与心理现状     

Control and Anticipation of Social Interruptions: Reduced Stress and Improved Task Performance1

Social interruptions are frequent occurrences that often have distressing consequences for employees, yet little research has gauged their effect on individuals. Participants were exposed to 2 social interruptions as they engaged in a computer task with an accepted performance goal. Participants who were able to anticipate social interruptions performed significantly better than did those who could not anticipate them. Participants who had the opportunity to prevent interruptions reported significantly less stress than those who did not have this opportunity. This reduction in stress resulted even when participants did not take advantage of this opportunity. Implications for job performance and job satisfaction are discussed. Organizational strategies for how leaders can help employees manage social interruptions are suggested.     

Effects of cancer rehabilitation on problem-solving, anxiety and depression: a RCT comparing physical and cognitive-behavioural training versus physical training

We tested the effects on problem-solving, anxiety and depression of 12-week group-based self-management cancer rehabilitation, combining comprehensive physical training (PT) and cognitive-behavioural problem-solving training (CBT), compared with PT. We expected that PT + CBT would outperform PT in improvements in problem-solving (Social Problem-Solving Inventory-Revised (SPSI-R)), anxiety and depression (Hospital Anxiety and Depression Scale (HADS)), and that more anxious and/or depressed participants would benefit most from adding CBT to PT. Cancer survivors (aged 48.8 ± 10.9 years, all cancer types, medical treatment completed) were randomly assigned to PT + CBT (n = 76) or PT (n = 71). Measurement occasions were: before and post-rehabilitation (12 weeks), 3- and 9-month follow-up. A non-randomised usual care comparison group (UCC) (n = 62) was measured at baseline and after 12 weeks. Longitudinal intention-to-treat analyses showed no differential pattern in change between PT + CBT and PT. Post-rehabilitation, participants in PT and PT + CBT reported within-group improvements in problem-solving (negative problem orientation; p < 0.01), anxiety (p < 0.001) and depression (p < 0.001), which were maintained at 3- and 9-month follow-up (p < 0.05). Compared with UCC post-rehabilitation, PT and PT + CBT only improved in anxiety (p < 0.05). CBT did not add to the effects of PT and had no extra benefits for higher distressed participants. PT was feasible and sufficient for durably reducing cancer survivors' anxiety.     

Lessons learned: the effect of prior technology use on Web-based interventions.

This study examined the role of regular prior technology use in treatment response to an online family problem-solving (OFPS) intervention and an Internet resource intervention (IRI) for pediatric traumatic brain injury (TBI). Participants were 150 individuals in 40 families of children with TBI randomly assigned to OFPS intervention or an IRI. All families received free computers and Internet access to TBI resources. OFPS families received Web-based sessions and therapist-guided synchronous videoconferences focusing on problem solving, communication skills, and behavior management. All participants completed measures of depression, anxiety, and computer usage. OFPS participants rated treatment satisfaction, therapeutic alliance, and Web site and technology comfort. With the OFPS intervention, depression and anxiety improved significantly more among technology using parents (n = 14) than nontechnology users (n = 6). Technology users reported increasing comfort with technology over time, and this change was predictive of depression at followup. Satisfaction and ease-of-use ratings did not differ by technology usage. Lack of regular prior home computer usage and nonadherence were predictive of anxiety at followup. The IRI was not globally effective. However, controlling for prior depression, age, and technology at work, there was a significant effect of technology at home for depression. Families with technology experience at home (n = 11) reported significantly greater improvements in depression than families without prior technology experience at home (n = 8). Although Web-based OFPS was effective in improving caregiver functioning, individuals with limited computer experience may benefit less from an online intervention due to increased nonadherence.     

Visual and haptic feedback contribute to tuning and online control during object manipulation

The authors employed a virtual environment to investigate how humans use haptic and visual feedback in a simple, rhythmic object-manipulation task. The authors hypothesized that feedback would help participants identify the appropriate resonant frequency and perform online control adjustments. The 1st test was whether sensory feedback is needed at all; the 2nd was whether the motor system combines visual and haptic feedback to improve performance. Task performance was quantified in terms of work performed on the virtual inertia, ability to identify the correct rhythm, and variability of movement. Strict feedforward control was found to be ineffective for this task, even when participants had previous knowledge of the rhythm. Participants (N = 11) performed far better when feedback was available (11 times more work, 2.2 times more precise frequency, 30% less variability; p < .05 for all 3 performance measures). Using sensory feedback, participants were able to rapidly identify 4 different spring-inertia systems without foreknowledge of the corresponding resonant frequencies. They performed over 20% more work with 24% less variability when provided with both visual and haptic feedback than they did with either feedback channel alone (p < .05), providing evidence that they integrated online sensory channels. Whereas feedforward control alone led to poor performance, feedback control led to fast tuning or calibration of control according to the resonant frequency of the object, and to better control of the rhythmic movement itself.     

Experiential differences between voluntary and involuntary job redundancy on depression,job‐search activity,affective employee outcomes and re‐employment quality

The current study used learned helplessness theory and legacy theory to examine experiential differences in voluntary vs. involuntary job redundancy in a baseline study (Study 1) and a 3‐month retest (Study 2). The sample for Study 1 comprised 102 job seekers who had voluntarily taken a job redundancy and 114 job seekers who had been made involuntarily redundant from their last job. Results at Study 1 showed that voluntarily redundant participants experienced lower levels of depression and engaged in more job‐search activity than those who experienced involuntary redundancy. Employees who became re‐employed 3 months later (voluntarily redundant N = 28, involuntarily redundant N = 26) were compared on depression, organizational commitment, perceived job insecurity and perceived re‐employment quality. The involuntarily redundant employees reported higher depression, lower organizational commitment, higher perceived job insecurity and lower perceived re‐employment quality. The voluntarily redundant employees also experienced a significant drop in depression upon re‐employment while the involuntarily redundant employees reported no significant changes to depression scores from baseline. Implications for practice and future research are discussed together with the limitations of the two studies.

Stress-oriented Analysis of Computerized Office Work

Abstract

The stress-oriented job analysis instrument ISTA was applied to a sample of 232 office jobs to analyse the impact of new technologies on the stressor-strain relationship. Scales measuring work content (complexity of work, variety), stressors (time pressure, organizational problems, interruptions, concentration necessities, social stressors), and resources (control at work, control over time) were developed and demonstrated desirable scale characteristics. The results showed positive correlations between stressors and psychological dysfunctioning (psychosomatic complaints, irritation). Computer work was associated with a decrease of work stressors, but also with decreased job content. Work places using different software systems (word processing, specialist, spreadsheet, and graphic programs) manifested different characteristics regarding work content, stressors, and resources. For example, when working with word processors, most stressors occurred at a medium daily computer work time. This indicates that strategies of work design which involve computer and non-computer work have to be used carefully.     

Personality correlates of employees' personal use of work computers.

The advent of the desktop computer has allowed organizations to help their employees become faster and more productive workers. Some employees, however, use their work computers in unproductive ways as well, such as sending personal email and playing computer games. We call this Personal Use of Work Computers (PUWC). Using a work computer for personal reasons deviates from many organizations' norms. In the current study, we surveyed employees at an educational institution and asked them to report how they use their computers at work. These respondents also answered questions related to their sensation seeking, impulsiveness, conscientiousness, and job satisfaction as well as demographic information. We found that people who use their computers in unproductive ways tend to be men, younger, more impulsive, and less conscientious. We also found that those who use their computers for riskier PUWC behaviors (like viewing sexual content) tended to have sensation seeking personalities.     

Effects of a cognitive-behavioural internet program on depression, vulnerability to depression and stigma in adolescent males: a school-based controlled trial

This study evaluated the effectiveness of a cognitive behaviour therapy Internet program (MoodGYM) for depressive symptoms, attributional style, self-esteem and beliefs about depression, and on depression and depression-vulnerable status in male youth. A total of 78 boys age 15 and 16 years were allocated to either undertake MoodGYM or to standard personal development activities. Outcomes were measured before commencement, post-program and 16 weeks post-program. There were no significant between-group differences in change scores pre- to post- or pre- to follow-up using the intention to treat sample or for participants with post- and/or follow-up data. For boys completing 3 or more modules there were small relative benefits of MoodGYM for depressive symptoms (Effect Size, ES = 0.34), attributional style (ES = 0.17) and self-esteem (ES = 0.16) at post-program, although only the effect for self-esteem was sustained at follow-up. Both groups showed improvement in their beliefs about depression at follow-up, with the control group showing a moderate relative benefit (ES = 0.40). While the numbers are small, there was a reduction in the risk of being depressed in the MoodGYM group of 9% at post-treatment compared with a slightly increased risk for the control group. The risk of being classified as vulnerable to depression reduced by 17% in the MoodGYM group at post-treatment compared with no change in risk for the control group. These reductions in risk for the MoodGYM group were not sustained at follow-up. The limitations of the study highlight several important challenges for MoodGYM and other self-directed Internet cognitive behaviour therapy programs. These include how to ensure enough of the program is received and that people who could potentially benefit access the program and continue to remain engaged with it, and how to enhance the sustainability of any benefits.     

Job apathy and work engagement: Moderating influence of perceived leader integrity and spiritual intelligence in a Nigerian mass transit company

This study explored the direct and interactive roles of job apathy, perceived leader integrity, and spiritual intelligence on work engagement among 206 Nigerian employees of a leading mass transit company (females = 33%; mean age = 35.81years, SD = 5.04; mean organisational tenure = 6.27 years, SD = 2.26). Results following moderated hierarchical multiple regression showed that work engagement was lower with job apathy and higher with perceived leader integrity and employee spiritual intelligence. Moreover, employees with a high perception of leader integrity reported being more work engaged, regardless of feeling apathetic about their job, compared to those with a low perception of leader integrity. Perceived leader integrity and spiritual intelligence are important for work engagement in Nigeria’s transportation sector setting.     

Performance enhancement in a semi-autonomous confined microsociety

Research in a continuously programmed human experimental laboratory has been directed toward identifying, defining, and expanding generalized knowledge concerning motivational factorswithin the structure of human behavioral repertoires that maintain and enhance performance. Participants (in groups of three) engaged in a series of repetitive work activities (e.g., word sorting and rug-hooking) for extended periods each day, while living continuously in a residential laboratory. Other parts of the day were spent either interacting socially with other participants or engaging in individual recreational activities. The percentage of time devoted to the various work tasks provided the basis for selecting one activity that occurred with high frequency and one with low frequency. Performance of the low-frequency activity was then required in order to gain access to the high-frequency activity. Under such contingencies, time devoted to the original low-frequency activity increased greatly, and the participants consistently did more than the required amount of the low-frequency work than was necessary to restore access to the restricted work activity. The theoretical significance of these findings resides in the clear demonstration that a time-based model of value applies as well to the enhancement of work-like performance as it does to voluntarily selected or preferred recreational activities.

组织政治氛围对员工疏离感的影响：自我决定动机的中介作用

验证组织政治氛围对员工疏离感的作用,探讨自我决定动机在二者间的中介作用。研究采用一般政治行为知觉量表、工作内外动机量表和工作疏离感量表对226名企事业单位的员工进行问卷调查。研究表明,组织政治氛围对员工疏离感的个人疏离和社会疏离均具有显著的预测作用;自我决定动机在组织政治氛围与员工的个人疏离感之间起部分中介的作用,但在组织政治氛围与员工的社会疏离感之间的中介作用不显著。这说明我国员工的个人疏离感一部分来自于组织政治氛围对员自我决定动机的削弱,而社会疏离感主要来自于组织政治氛围的直接影响。     

Éléments contextuels associés à l'émission de comportements d'agitation verbale présentés par des personnes âgées institutionnalisées atteintes de démence

This research examines the contexts in which verbal agitation (VA) behaviours occur. The study was conducted with 15 participants suffering from dementia who live in an institution and display agitated behaviours. Participants were subject to observation assisted by a hand-held computer. The frequency and duration of agitation episodes were calculated. The time of day, the location, and the activity engaged in, the presence of other persons and use of physical restraint were noted. A total of 180 observation hours were conducted, with each participant being observed for 12 hours, from 8 a.m. to 8 p.m. The results show that the participants are verbally agitated 10% of the time. VA is manifested when participants are in their rooms (94%), not engaged in a specific activity (81%), alone (80%) and physically restrained (78%). VA occurs mainly after 2 p.m. (73%). Certain contextual characteristics rather than others are associated with greater VA concentrations.
