The Family Rule Concept in the Theory of Family Therapy: Part II**

In the second part of this paper the author traces the processes by which it is possible to learn rule conforming behaviours without necessarily being able to formulate the rule or see any point in the rule; the rule is followed blindly. In following a rule blindly a person may nevertheless be engaged in a practice which has a systemic function; he argues that when we positively connote symptomatic behaviours in the process of making paradoxical systemic interventions, we should avoid any suggestion that the family members are acting deliberately with the goal of “helping” in mind.     

eHealth recruitment challenges

Little is known about effective eHealth recruitment methods. This paper presents recruitment challenges associated with enrolling African-American girls aged 8–10 years in an eHealth obesity prevention program, their effect on the recruitment plan, and potential implications for eHealth research.Although the initial recruitment strategy was literature-informed, it failed to enroll the desired number of girls within a reasonable time period. Therefore, the recruitment strategy was reformulated to incorporate principles of social marketing and traditional marketing techniques. The resulting plan included both targeted, highly specific strategies (e.g., selected churches), and more broad-based approaches (e.g., media exposure, mass mailings, radio advertisements).The revised plan enabled recruitment goals to be attained. Media appeared to be particularly effective at reaching the intended audience. Future research should identify the most effective recruitment strategies for reaching potential eHealth audiences.     

Data entry workers perceptions and satisfaction response to the "stop and stretch" software program

Cumulative Trauma Disorder (CTD) is a collection of chronic musculoskeletal disorders caused by frequent, sustained, and repetitive movements, most notably by computer usage at the workplace. A computer based break reminder program (Stop and Stretch) has been developed and installed to prevent CTDs caused by prolonged computer usage at the workplace. We investigated users' opinions to the Stop and Stretch program at their work place. 19 computer users were recruited as the subjects of the study. We conducted a survey after all the subjects used the Stop and Stretch program for one month. Among the nineteen subjects, 52.5% or 10 noticed a difference of symptoms after using the program; 63.3% or 12 thought the program had positive effect on their productivity; 100% or all 19 thought the program was easy to follow; 100% or all 19 thought it was helpful; 94.7% or18 were satisfied with the program; and the same value would recommend the program to others. When grouped into those who had prior experience with using stretch and exercise as part of their work routine15 subjects had no prior experience; and 14 participants within that group were satisfied or very satisfied with the program; 93.3% or 14 would recommend it to co-workers; and over half of those 15 thought the program is easy to use. The study provided insight to the response to using "stretch break software" and provided indicators of satisfaction with the Stop and Stretch program and that the program had sufficient usability and acceptance within a workplace setting which might be applied in other work settings similar to these.     

The opportunity to contribute: disability and the digital entrepreneur

ABSTRACT

A range of scholarly work in communications, informatics, and media studies has identified ‘entrepreneurs’ as central to an emerging paradigm of digital labor. Drawing on data from a multi-year research project in the virtual world Second Life, I explore disability experiences of entrepreneurism, focusing on intersections of creativity, risk, and inclusion. Since its founding in 2003, Second Life has witnessed significant disability participation. Many such residents engage in forms of entrepreneurship that destabilize dominant understandings of digital labor. Most make little or no profit; some labor at a loss. Something is being articulated through languages and practices of entrepreneurship, something that challenges the ableist paradigms that still deeply structure both digital socialities and conceptions of labor.

Disability is typically assumed to be incompatible with work, an assumption often reinforced by policies that withdraw benefits from disabled persons whose income exceeds a meagre threshold. Responses to such exclusion appear when disabled persons in Second Life frame ‘entrepreneur’ as a selfhood characterized by creativity and contribution, not just initiative and risk. In navigating structural barriers with regard to income and access, including affordances of the virtual world itself, they implicitly contest reconfigurations of personhood under neoliberalism, where the laboring self becomes framed not as a worker earning an hourly wage, but as a business with the ‘ability’ to sell services. This reveals how digital technology reworks the interplay of selfhood, work, and value – but in ways that remain culturally specific and embedded in forms of inequality.     

Choices and rights: eugenics, genetics and disability equality

Pre-natal screening is a highly contentious ethical and political issue. The paper discusses aspects of the debate, and focuses on the context in which reproductive decisions are taken and the lack of a disabled voice in genetic policy. Eugenic aspects of the practice of genetics, particularly surrounding the role of professionals and the notion of consent, are explored. The paper concludes with recommendations on a disability equality approach to genetics and obstetrics.     

Evaluation of Alternative Cohort-Component Models for Local Area Population Forecasts

It is generally accepted by demographers that cohort-component projection models which incorporate directional migration are conceptually preferable to those using net migration. Yet net migration cohort-component models, and other simplified variations, remain in common use by both academics and practitioners because of their simplicity and low data requirements. While many arguments have been presented in favour of using one or other type of model, surprisingly little analysis has been undertaken to assess which tend to give the most accurate forecasts. This paper evaluates five cohort-component models which differ in the way they handle migration, four of which are well known, with one—a composite net migration model—being proposed here for the first time. The paper evaluates the performance of these five models in their unconstrained form, and then in a constrained form in which age–sex-specific forecasts are constrained to independent total populations from an extrapolative model shown to produce accurate forecasts in earlier research. Retrospective forecasts for 67 local government areas of New South Wales were produced for the period 1991–2011 and then compared to population estimates. Assessments of both total and age-specific population forecasts were made. The results demonstrate the superior performance of the forecasts constrained to total populations from the extrapolative model, with the constrained bi-regional model giving the lowest errors. The findings should be of use to practitioners in selecting appropriate models for local area population forecasts.
