This study was a systematic extension of Karmali, Greer, Nuzzulo-Gomez, Ross, and Rivera-Valdes (2005) and Ahearn, Clark, MacDonald, and Chung (2007). We investigated the effects of a tact correction procedure on stereotypic vocalizations in 4 children diagnosed with autism who ranged in age from 6 to 16 years. Participants had limited vocal verbal repertoires and were primarily dependent on prompts for the emission of appropriate vocalizations. A multiple-baseline design across participants was used. Data were collected on instances of stereotypic vocalizations and independent tacts during baseline conditions and on instances of stereotypic vocalizations, independent tacts, and echoic-tacts during intervention. Procedural integrity and social validity data were also obtained. The results indicated a decrease in stereotypic vocalizations for 3 of the 4 participants and a slight increase in appropriate vocal verbal behavior (i.e., tacting) for all participants. The study provides support for the use of tact correction procedures to decrease stereotypic vocalizations and increase appropriate vocalizations in children with autism. 相似文献

The authors examine whether the surge in housing refinance and equity withdrawal generated by the housing boom disproportionately affected older households in terms of decisions on whether to refinance, whether to withdraw equity, and how much to withdraw, and how in turn these decisions affected their household wealth. Using the Federal Reserve's Survey of Consumer Finances, the authors found the highest rates of refinancing and cashing out equity among older (although not necessarily the oldest) households. The authors also found that appreciation in house value, being a baby boomer, and having higher household income were the factors that most increased the probability of refinancing and withdrawing equity. Amounts cashed out were higher among older than among younger households. Ordinary least squares (OLS) estimates showed that amounts withdrawn were increased by price appreciation, financial assets, and income, along with being a "pre-boomer" or "early boomer." Older cohorts displayed larger wealth effects than younger ones, but their withdrawn equity was a smaller percentage of total net worth. A relatively small percentage of respondents' dollars was used for consumption, and most dollars were used for home improvement, other investment, or debt repayment. However, massive equity withdrawal and the subsequent collapse of housing prices have caused housing leverage to soar, putting some homeowners "underwater" and jeopardizing others' retirement preparedness. The ensuing housing finance crisis raises numerous policy issues, from reform of mortgage underwriting, securitization, servicing, and foreclosure procedures, to potential limitations on borrowing against unrealized housing equity gains, to enhanced government transfers for distressed older homeowners, to local and state revenue policy changes. 相似文献

This article seeks to explore the extent to which the military rebuilds or reframes masculinities as a means of meeting the aims of the process of militarization. It focuses on the dimensions of military masculinities that can be distinguished as distinctive in practice. Drawing on Etienne Wenger's notion of communities of practice, this research asks how military men orient themselves in their social and material world, considering the role of practice in the development of military masculinities. A total of 71 semi‐structured interviews were conducted with 53 male and 18 female personnel of various ranks working in the Army, Navy and Royal Air Force. Six focus groups were also carried out (with a total of 10 male and six female participants). Thematic analyses of the narratives indicated that one outcome of militarization is the construction of military masculinities. The military reframes masculinities as a means of meeting the aims of the process of militarization. Dimensions of military masculinities can be distinguished as attributes and qualities and masculinities that are distinctive to the military are constructed through military practice. A strong sense of belonging to the military community of practice is fundamental to the development of military masculinities. In order to feel that one belongs, the recognition and acceptance of others is needed. Those who share the attributes and comply with the practices peculiar to the military achieve this recognition. 相似文献

Self-forgiveness is generally understood to be a mechanism that restores and improves the self. In the current study, we examine the possible deleterious consequences of forgiving the self among gamblers-specifically in regard to gamblers' readiness to change their problematic behavior. At a large Canadian university, 110 young adult gamblers' level of gambling pathology was assessed, along with their readiness to change and self-forgiveness for their gambling. Participants were 33 females and 75 males (2 unspecified) with a mean age of 20.33. Results revealed that level of pathology (at risk vs. problem gamblers) significantly predicted increased readiness to change. Self-forgiveness mediated this relationship, such that level of gambling pathology increased readiness to change to the extent that participants were relatively unforgiving of their gambling. Implications for seeking professional assistance as well as treatment and recovery are discussed. 相似文献

Dixon and Johnson (Anal Gambl Behav 1: 44–49, 2007) proposed the Gambling Functional Assessment as a tool to identify the consequences maintaining the respondent’s gambling
behavior, but subsequent studies on its psychometric properties suggested that it could use improvement. The present study
investigated the internal consistency of the Gambling Functional Assessment—Revised using the responses of 1,060 undergraduate
students. Temporal reliability was assessed by a second administration of the measure four (n = 87) or twelve (n = 98) weeks after the first administration. Temporal reliability was also compared to the South Oaks Gambling Screen (Lesieur
and Blume in Am J Psychiatry 144: 1184–1188, 1987), which was also administered at both time points. Internal consistency measures were good to excellent, even when potential
non-gamblers were excluded from the analyses. Temporal stability was also very good, with the possible exception of the consequence
of “escape” at 12 weeks. The Gambling Functional Assessment—Revised represents a potentially useful tool for researchers and
therapists interested in why respondents are gambling. 相似文献

A random digit dialing telephone survey was used to interview 8,467 adults in Ontario, Canada. The NODS-CLiP was used to identify
a representative sample of 730 gamblers (54.3% male, mean age 45.3 years) with possible past year gambling problems in order
to explore factors that might affect disordered gamblers’ motivators for seeking gambling-related help. A final sample of
526 gamblers provided useable data on possible reasons for and barriers to seeking help, awareness of services, self-perception
of gambling problems and experience with help-seeking. Financial and relationship issues were the most frequently volunteered
motivators. However, over two-thirds of the respondents could not think of a reason for seeking help. Gamblers who had self-admitted
or more severe problems, who knew how to get help, who were employed and had more education, and who identified possible barriers
to seeking help were more likely to suggest motivators, especially financial ones. More research is recommended on gamblers’
trajectory towards recognition of a gambling problem, the process of overcoming specific barriers to treatment, and the role
of social advantage (e.g., education and employment), in order to devise educational campaigns that will encourage earlier
help-seeking among disordered gamblers. 相似文献

This work studies biomechanical hazards to which the workforce of Instituto Nacional de Metrologia, Qualidade e Tecnologia Industrial (Inmetro) is exposed. It suggests a model for ergonomic evaluation of work, based on the concepts of resilience engineering which take into consideration the institute's ability to manage risk and deal with its consequences. Methodology includes the stages of identification, inventory, analysis, and risk management. Diagnosis of the workplace uses as parameters the minimal criteria stated in Brazilian legislation. The approach has several prospectives and encompasses the points of view of public management, safety engineering, physical therapy and ergonomics-oriented design. The suggested solution integrates all aspects of the problem: biological, psychological, sociological and organizational. Results obtained from a pilot Project allow to build a significant sample of Inmetro's workforce, identifying problems and validating the methodology employed as a tool to be applied to the whole institution. Finally, this work intends to draw risk maps and support goals and methods based on resiliency engineering to assess environmental and ergonomic risk management. 相似文献

The current paper presents the study of organizational stressors survey carried out in a military institute, responsible for researches of high demand on aerospace technology. The study considered the theoretical framework of Organizational Ergonomics, combined with the technical guidelines of Psychology applied to Work Safety. The participatory approach was used on daily work assessment and decision making, aiming the adoption of corrective and preventive measures, considering possible distortions and imbalances between prescribed and actual activities. Thus, it was sought to engage and encourage the participation of the Institute's workers in the reflection/creation of better solutions to daily problems and to achieve productivity, without prejudice in the occupational health and safety. 相似文献
