    A more negative implicit evaluation of unhealthy food stimuli and a more positive implicit evaluation of a weight-management goal have been shown to predict lower consumption of unhealthy food. However, the associations between these evaluations, temptation to indulge and consumption of unhealthy food remain unclear. The current study investigated whether temptation would mediate the relationship between implicit food and goal evaluations and consumption (resembling an antecedent-focused route to self-control of eating), or whether those evaluations would moderate the relationship between temptation and consumption (resembling a response-focused route). A sample of 156 women (17–25 years), who tried to manage their weight through healthy eating, completed two implicit association tasks assessing implicit food and goal evaluations, respectively. Intake of four energy-dense snack foods was measured in a task disguised as a taste test, and participants reported the strength of experienced temptation to indulge in the snacks offered. Negative implicit food evaluation was associated with lower snack intake, and temptation mediated this relationship. Implicit goal evaluation was unrelated to both temptation strength and snack consumption. The findings contribute to an understanding of how negative implicit unhealthy food evaluation relates to lower consumption, namely through the mediation of temptation to indulge in those foods

    Externalizing the threat from within: A new direction for researching associations between suicide and psychotic experiences

    A recent suicidal drive hypothesis posits that psychotic experiences (PEs) may serve to externalize internally generated and self-directed threat (i.e., self-injurious/suicidal behavior [SIB]) in order to optimize survival; however, it must first be demonstrated that such internal threat can both precede and inform PEs. The current study conducted the first known bidirectional analysis of SIB and PEs to test whether SIB could be considered as a plausible antecedent for PEs. Prospective data were utilized from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative birth cohort of 2232 twins, that captured SIB (any self-harm or suicidal attempt) and PEs at ages 12 and 18 years. Cross-lagged panel models demonstrated that the association between SIB at age 12 and PEs at age 18 was as strong as the association between PEs at age 12 and SIB at age 18. Indeed, the best representation of the data was a model where these paths were constrained to be equal (OR = 2.48, 95% CI = 1.63–3.79). Clinical interview case notes for those who reported both SIB and PEs at age 18, revealed that PEs were explicitly characterized by SIB/threat/death-related content for 39% of cases. These findings justify further investigation of the suicidal drive hypothesis

    Why do an online Change Laboratory?

    Get PDF
    This technical submission was created collaboratively, by a group of researchers united by shared interests and experiences in conducting research online using the Change Laboratory methodology. Our current contribution seeks to inform and engage colleagues, setting out a collaborative response to a relatively unsophisticated yet reflexive and timely question: Why do an online Change Laboratory? To us, it seems that this question could be interpreted in multiple ways: why should people become involved in an online Change Laboratory, as discrete from an onsite Change Laboratory; why should people become involved in an online Change Laboratory, as discrete from using other online options; or why should people become involved in any type of research-intervention at all. As individual researcher-interventionists, who meet regularly to share our experiences and interests in online Change Laboratories, we also interpret this question in multiple ways, and we hope that our collaborative response reflects our diversity of thought (a closing section of this paper described how we worked in its production). We seek to encourage colleagues to further explore these and other questions about online Change Laboratories, and we call for others to join us in purposeful conversations to advance the methodology

    Beyond 'pivoting': Capitalising on new Knowledge and experience: in Technology and educational ‘pivoting’ in the wake of the Covid-19 pandemic: A collected commentary

    Get PDF
    The present document presents 13 commentaries that address the broad topic of the special issue Technology and educational 'pivoting' in the wake of the Covid-19 pandemic and, in some cases, specific articles from the issue itself. Since the launch of the journal in 2020, we have been explicit about our aspiration that Studies in Technology Enhanced Learning might serve as a vehicle for scholarly conversation (Bligh & Lee, 2020).Victoria I.

    Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

    Get PDF
    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

    Interstate migration of the US poverty population: Immigration “pushes” and welfare magnet “pulls”

    Full text link
    This study evaluates the social and demographic structure of poverty migration during the 1985–90 period based on an analysis of recent census data. Particular attention is given to the roles of two policy-relevant factors that are proposed to be linked to poverty migration. The first of these is the role of immigration from abroad and its effect on the net out-migration of longer-term residents with below-poverty incomes, from States receiving the highest volume of immigrants. Such a response, it is argued, could result from job competition or other economic and social costs associated with immigration. The second involves the poverty population “magnet” effect associated with State welfare benefits (AFDC and Food Stamp payments) which has come under renewed scrutiny in light of the impending reform of the federal welfare program. The impact of both of these factors on interstate poverty migration is evaluated in a broader context that takes cognizance of other sociodemographic subgroups, and State-level attributes that are known to be relevant in explaining internal migration. This research employs an exceptionally rich data base of aggregate migration flows, specially tabulated from the full migration sample of the 1990 US census (based on the “residence 5 years ago” question). It also employs an analysis technique, the nested logit model, which identifies separately the “push” and “pull” effects of immigration, welfare benefits, and other State attributes on the migration process. Our findings are fairly clear. The high volume of immigration to selected US States does affect a selective out-migration of the poverty population, which is stronger for whites, Blacks and other non-Asian minorities as well as the least-educated. These results are consistent with arguments that internal migrants are responding to labor market competition from similarly educated immigrants. Moreover, we found that the impact of immigration occurs primarily as a “push” rather than a reduced “pull.” In contrast, State welfare benefits exert only minimal effects on the interstate migration of the poverty population—either as “pulls” or “pushes,” although some demographic segments of that population are more prone to respond than others. In addition to these findings, our results reveal the strong impact that a State's racial and ethnic composition exerts in both retaining and attracting migrants of like race and ethnic groups. This suggests the potential for a greater cross-state division in the US poverty population, by race and ethnic status.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43484/1/11111_2005_Article_BF02208337.pd

    Visual forms of mediating artefacts:A research-intervention in engineering education

    No full text
    This paper describes a research-intervention to change technology-enhanced learning (TEL), in a setting of engineering education. It examines how participants used visual forms of mediating artefacts, that is, the means by which the group came together, examined and changed their own TEL activity. Engineering education, an arena that is highly dependent on visualisation and the promotion of visual literacy, largely constrains visual representations to instrumentalist and work-related applications, for the mental rehearsal of engineering solutions. This paper instead describes an activity theoretical perspective, where visual representations of social activity became mediating artefacts, sitting between a collective subject (of learners, lecturers and managers in engineering education) and the object of their activity (to change their TEL activity). In the study described, participants identified, curated and engaged with visual forms of mediating artefacts: stimulating their need and potential for change; assisting their questioning of social conditions and knowledge; and mitigating the reversal and regression of their endeavours. The research-intervention used the Change Laboratory methodology, engaging them in collaborative and agentic double-stimulation tasks through a process of expansive learning. The core claim is that visual forms of mediating artefacts played a crucial role in the group’s qualitatively meaningful change to TEL, and in engendering their transformative agency
