Why primary prevention is important,and how to promote resilience: CADCA

Last week's annual leadership meeting of Community Anti‐Drug Coalitions of America (CADCA) focused, as it always does, on primary prevention. This is defined as preventing the use of drugs (including alcohol), mainly in youth. There were more than 3,200 attendees, 500 of whom were middle and high schoolers drawn from the coalitions funded by the Drug‐Free Communities (DFC) program, with CADCA member organizations benefiting from training in how to use this funding.     

Grading with norm-referenced or criterion-referenced measurements: To curve or not to curve,that is the question

Assigning grades is an integral and everyday part of social work education. However, social work educators, especially those teaching the academically-based as opposed to practice-based courses, must decide whether to use norm-referenced or criterion-referenced measurements to grade exams and other assignments. Norm-referenced measurement is commonly called grading on a curve in higher education. While grading on the curve is not obsolete in academia, I have eliminated it in my courses. New and perhaps experienced social work educators may benefit from a review of both grading methods. This article examines both sides of a grading issue relevant to the wider context of higher education and, therefore, relevant to social work education. Grading with norm-referenced or criterion-referenced measurements is reviewed along with issues related to both types of grading. I will describe why I grade with criterion-referenced measurement and why I believe it is a better choice for social work education.     

Action,Technology, and the Homogenisation of Place: Why Climate Change is Antithetical to Political Action

According to Hannah Arendt, the concept of ‘political action’ is a fundamental component of the human condition because it encapsulates how the uniqueness of each human being intersects to create unpredictable political initiatives and effects. Recently, despite being one of the most daunting political challenges ever faced by humanity, there has been a noted collective action failure, or inaction, concerning the global threat of anthropogenic climate change. Why? This article seeks to explain this political inaction in a new way: by examining the metaphysical role that technology plays in disclosing the climate as a thinkable and global object. After applying the philosophy of Martin Heidegger to the complex mathematical general circulation models (GCMs) used by the Intergovernmental Panel on Climate Change (IPCC), this article details how the metaphysics underlying GCMs manifests the perceivable world by ‘enframing’ it, or by implicitly representing subjects, objects, and Nature itself, as a predictable, calculable, and orderable relation of static forces. When this metaphysical and mathematical uniformity constructs the climate as a calculable object that is globalised through the IPCC, it is ultimately found to be contradictory to the distinctness and unpredictability necessary for distinct human action to occur. Paradoxically, therefore, political action is argued to be metaphysically antithetical to the technologically enframed science, politics, and discourse, of global climate change itself. The importance of distinct and plural human places, when filtered through GCMs, becomes subsumed by the climate as a homogenous, calculative, and politically inactive, global object.     

Medical ethics and the civil rights movement. Why informed consent is too little, too late.

Medical ethics is viewed as one phase of the human rights movement begun by blacks in the 1950s and then continued by feminists, consumerists, and bioethicists.     

Imperial contradictions: is the Valley a watershed,region, or cyborg?

Is California's Imperial Valley a watershed? If so, at what level and by what topographic logic? Is it a region? If so, at what level and by what geographic logic? Are its boundaries natural, political, or multivalent on different scales? In short, this essay looks at the special (re)production of environmental conditions within a cyborg world. Here, the Valley is comprised of (a) Colorado River water; (2) migratory waterfowl; (3) the accidentally manufactured, but intentionally seeded food chain of the Salton Sea (3) the San Andreas Fault, (4) Mexican field labor; (5) public universities extension services; (6) global markets and supply chains; (7) international biotechnology, chemical and seed conglomerates, and (8) state and federal regulation of water rights, regulations and markets. The Valley is a cyborg, a historical entity comprised interdependently of nature, technoscience and humanity. This, characterization, however, raises problems with conceptions of the massive losses of migratory waterfowl from avian cholera at the Salton Sea, the agroecological devastation caused by the unintentional introduction of the Silver Leaf whitefly, and the “wastage” of constrained water rights as environmental crises of nature. The articulation of a cyborg perspective sees the environmental conditions of the Valley as the product of relations comprised of uneven and indeterminate ecological process, technoscientific trajectories, and human practices. Extending the cyborg's integration of nature, technology and social agency, a relational reading of James O’Connor's second contradiction of capitalism thesis is developed. O’Connor's political ecology and Haraway material semiotics, while broadly operating at different levels of analysis, prove surprisingly resonant.     

Why Extended Time on Newstart is Unsuitable for Aboriginal and Torres Strait Islander Australians Living with a Disability

ABSTRACT

Many Australians living with a disability find themselves recipients of Newstart Allowance when applying for the Disability Support Pension (DSP). Newstart Allowance is designed as a short-term payment for people looking for work, with a lower fortnightly payment and limited medical and transport subsidies compared to the DSP. This paper describes the financial challenges of living with a disability while on Newstart Allowance. With a focus on the experiences of Aboriginal and Torres Strait Islander (Indigenous) Australians from two regional towns, qualitative semistructured interviews and focus groups documented experiences of 39 community members and 21 medical and nonmedical service providers supporting clients living with a disability on Newstart Allowance. Four themes were identified: (i) living with severe financial hardship, (ii) challenges complying with the DSP application, (iii) being financially penalised for not complying with Newstart Allowance conditions, and (iv) supporting community members to manage severe financial stress. Although people living with a disability on Newstart were experiencing severe hardship and poverty, there was limited participation of Centrelink-employed social workers within their described experiences with Centrelink. We argue that social workers can work to humanise human service settings and potentially help to mitigate these financial challenges.

IMPLICATIONS

• Indigenous Australians living with a disability experience severe disadvantage and poverty while living on Newstart Allowance.

• Social workers must be easily accessible at Centrelink customer service centres and to Newstart Allowance recipients to help coordinate service engagement.

• Newstart Allowance should be increased to ensure recipients can respond to cost of living pressures.

     

More or less guanxi: Trust is 60% network context, 10% individual difference

The strong ties known in China as guanxi can be distinguished by a high level of trust relatively independent of the surrounding social structure. Using network data from a stratified probability sample of 700 entrepreneurs citing 4664 contacts, we study guanxi relative to other relations to learn how much individual differences such as well-being, business differences, political participation and demographic factors matter for the guanxi distinction. Two findings stand out: First, the connection between trust and social network is robust to most differences between individuals, especially business and political differences. Trust variance is 60% network context, and 10% individual differences. Trust increases within a relationship as network closure increases around the relationship, but some relationships mature into guanxi ties within which trust is high and relatively independent of the surrounding social structure. Second, when individual differences matter, they concern social isolation. Guanxi ties are more distinct in the networks around entrepreneurs with small, marginal families, and around those with small, closed networks. Both categories of entrepreneurs are likely to experience difficulties with respect to resource access and doing business with people beyond their network, which may explain why longstanding guanxi ties linked to important events are particularly distinct for these entrepreneurs.     

Marital relationships and purchasing decisions — to buy or not to buy,that is the question

Wives and husbands from 47 households rated their wellbeing in situations, where they imagined either to buy or not to buy a desired product, with their spouse either agreeing or disagreeing with the purchase. The product was female-specific for wives and male-specific for husbands. For 23 households the product was relatively cheap, for 24 households the subjects imagined to desire an expensive commodity. The approach was similar to Kelley and Thibaut's (1978) analysis of interdependence matrices. The data, in general, support the following hypotheses: (a) When the partner objects the purchase, the utility of the product will outweigh the perceived social costs more for husbands than for wives, especially in male-dominated families; (b) the wife's wellbeing with purchase decisions will depend more than her husband's wellbeing upon the partner's agreement, especially in male-dominated families, (c) the husband's wellbeing in conflict (buying a product despite the partner's objection) will be positively related with his dominance and vice versa; (d) mutual appraisal of situations will correspond higher in happy than in unhappy couples.The results are discussed with respect to differences in male and female strategies to cope with authority and social emotions in buying decisions. Shortcomings of economic theories on determinants of family consumer decisions are pointed out.     

Staying with People Who Slap Us Around: Gender,Juggling Responsibilities and Violence in Paid (and Unpaid) Care Work

Little is actually known about women's occupational health, let alone how men and women may experience similar jobs and health risks differently. Drawing on data from a larger study of social service workers, this article examines four areas where gender is pivotal to the new ways of organizing caring labour, including the expansion of unpaid work and the use of personal resources to subsidize agency resources; gender‐neutral violence; gender‐specific violence and the juggling of home and work responsibilities. Collective assumptions and expectations about how men and women should perform care work result in men's partial insulation from the more intense forms of exploitation, stress and violence. This article looks at health risks, not merely as compensable occupational health concerns, but as avoidable products of forms of work organization that draw on notions of the endlessly stretchable capacity of women to provide care work in any context, including a context of violence. Indeed, the logic of women's elastic caring appear crucial to the survival of some agencies and the gender order in these workplaces.     

Water,sediment, and nutrient runoff from urban lawns established on disturbed subsoil or topsoil and managed with inorganic or organic fertilizers

Urban runoff has become an increasingly important environmental concern in recent years. With increasing urbanization, turfgrass area has substantially expanded in North America, and these lawns are often established on subsoil stripped of topsoil. In this study, 24 turfgrass-type tall fescue (Festuca arundinacea) plots were established on subsoil or topsoil, and managed with inorganic fertilizer (Scott’s Turf Builder®), organic fertilizer (Nature’s Touch® with enzymes), or no fertilizer (control). A one-hour simulated rainfall at 8.9 cm/hour was applied to the plots, and the time to runoff initiation and total runoff volume were measured. Runoff water samples were analyzed to quantify the amounts of sediment, N (NH₄-N), P, K, and S losses. The results indicated that runoff initiation time was almost half in subsoil lawns (12.5 min) than in topsoil lawns (23 min). The total runoff volume and sediment loss were significantly larger in subsoil lawns (11,900 ml and 3,700 mg, respectively) than in topsoil lawns (2,200 ml and 900 mg, respectively). Although the N, P, K, and S losses in runoff were low, they were significantly higher from the subsoil-based than topsoil-based lawns, and were higher from inorganic fertilizer treated lawns than those treated with organic fertilizer. These results highlight the significance of topsoil preservation in city planning and urban development with respect to urban run-off and water quality and show distinct benefits of organic lawn management practices over the conventional inorganic practices for maintaining urban water quality.     

Open Road or Blind Alley? Welfare Reform, Mothers, and Children with Disabilities

Welfare reform was examined for 39 Michigan families whose children have significant health or intellectual and behavioral disabilities. As a group, these families received little specialized assistance or services to address their unique needs. Family-cited barriers to self-sufficiency included poorly trained welfare caseworkers, limited public transportation, and inadequate child care. Having an older child was the only discriminating variable between working and non-working mothers. However, working mothers only had temporary positions with no benefits and low pay. All families, whether employed or not, lived below the poverty line.     

Urbanization is not associated with increased abundance or decreased richness of terrestrial animals - dissecting the literature through meta-analysis

The widely accepted consensus is that urbanization increases abundance but reduces species richness of animals. This assumption is the premise for empirical tests and theoretical explanations. We studied the association of urbanization with abundance and species richness of different animal taxa in 20 and 26 published articles reporting abundances and richness, respectively via meta-analysis. Because some articles had multiple estimates, we analyzed 40 and 58 estimates of abundance and richness, respectively. Contrary to conventional wisdom, the overall abundance of terrestrial animals was not higher in urban areas, but instead actually lower, while we failed to confirm the conventional thinking of lower species richness with urbanization. These findings cannot, however, be generalized across all cities and animal species, as conflicting differences were reported among geographical regions, animal taxa. Our results question the conventional wisdom that urbanization generally increases abundances while reducing species richness, and highlights the variability of urbanization effects on diversity among taxa and geographic regions.     

Exercise or physical activity and cognitive function in adults with type 2 diabetes,insulin resistance or impaired glucose tolerance: a systematic review

Background

Diabetes is an important risk factor for cognitive impairment. Although some studies suggest that physical exercise can minimize age-related cognitive declines or improve brain morphology or function, benefits in diabetes or impaired glucose tolerance are unclear. Therefore, our aim was to evaluate the efficacy of exercise or physical activity on cognition in adults with type 2 diabetes, insulin resistance or impaired glucose tolerance.

Methods

An electronic search for studies published from the earliest record until February 2017 was conducted using Medline, EMBASE, SPORTDiscus, CINAHL, and PsycINFO. Any experimental or observational study designs were included, as long as they were conducted in individuals of any age with type 2 diabetes, insulin resistance or impaired glucose tolerance, and they directly examined exercise/physical activity effects on cognitive outcomes or the relationship between changes in cognition and changes in either insulin resistance and glucose homeostasis. Study quality was assessed using the PEDro scale; data on participant and intervention characteristics and outcomes were extracted.

Results

Six studies enrolling 2289 participants met the eligibility criteria. Quality was modest and effect sizes variable and mostly small or negligible. Overall, four of the six studies (67%) reported significant benefits of greater exercise/physical activity participation for some aspects of cognition, but only 26% of cognitive outcomes were significant across all trials. Clinical improvements in insulin resistance/glucose homeostasis were related to improvements in cognitive function in three studies. Overall results were inconsistent, with benefits varying across exercise types and cognitive domains.

Conclusions

Literature does not provide evidence that physical activity or exercise interventions contribute to a better cognitive function in patients with type 2 diabetes or impaired glucose tolerance. Large-scale, long-term, robust randomized controlled trials are required to determine if exercise improves cognition in this high-risk cohort, and to investigate putative mechanistic links between cognition, body composition, metabolism, and inflammation in diabetes and related metabolic syndromes.

     

Ceasing of muscle function with aging: is it the consequence of intrinsic muscle degeneration or a secondary effect of neuronal impairments?

Aging is associated with a significant decline in neuromuscular function leading to an eventual loss of independence and mobility of senescent people. Age-related sarcopenia, characterised by a reduction in muscle mass and strength, is considered one of the most striking features of aging at the level of the skeletal muscle. Morphological alterations in skeletal muscle can be considered as one of the consequences responsible for muscle weakness in the aged population. Beyond 60 years of age, human muscle undergoes a process of continuous denervation and reinnervation, due to an accelerating loss of motor units. It appears evident that phenotypic alterations in muscle depend on the motor drives provided by the nervous system. Because the peripheral nerves, the neuromuscular junction and motor neurons exhibit degenerative features during advanced age, sarcopenia does not seem to intrinsically develop, but is rather a secondary effect of impaired neuronal function. It is therefore recommended that elderly subjects undergo an exercise program that is aimed towards the improvement of coordinative skills and of muscle strength.
