A systematic review of the relationship between urban agriculture and biodiversity

Urban agriculture is a unique form of agriculture that can provide fresh, local produce for urban residents, and may benefit biodiversity by decreasing the need to expand agriculture into natural areas as well as enhancing biodiversity in urban areas. However, although urban agriculture is also often cited as promoting biodiversity in urban areas, the extent of empirical evidence for such claims has not been studied. Here we systematically review the relationship between urban agriculture and biodiversity in the scientific literature. We strictly define urban agriculture as areas in cities that grow produce specifically for human consumption. We examined 148 papers from 2000 to 2017, of which only 24 studies fit our definition of urban agriculture, and of those, only 18 both involved urban agriculture and measured biodiversity. Of the studies that did measure biodiversity, some showed increases in diversity compared to urban vacant lots, but other showed no difference. Moreover, these studies were mostly focused on plants and invertebrates and were conducted almost exclusively in North America. In order to use the generalization that urban agriculture will have a positive influence on urban biodiversity, more studies will need to be conducted across a wider geographic range worldwide (particularly in developing countries in the tropics) and on a greater diversity of species and taxa (e.g., herpetiles, birds and small mammals). Such studies will likely increase in conservation importance as urban expansion and agricultural demands increase globally.     

Teil-autonome Arbeitsteams oder tayloristische Produktionslinie? Welche Erkenntnisgewinne bieten simulationsbasierte Work Design Trainings

Digitalisation, flexible job markets, new technologies and innovative forms of collaboration constitute increasing challenges for employers and the design of modern work. But how can we deal with these challenges and what do we know about the effect of good versus bad work design? Based on the job demands-resources model (JRM), we present a simulation-based training during which participants experience the effects of different work characteristics. We focus on the moderating effects of job control and job demands: The JRM assumes that job demands and job control interactively affect employee exhaustion and work engagement: Jobs with high control can buffer the strain-enhancing effect of job demands (buffer hypothesis) and increase work engagement (active learning hypothesis). We test these hypotheses in a workplace simulation during which participants have to produce ice-cream. Our results support the buffer hypothesis but not the active learning hypothesis. We discuss the added value of work design simulations for organisations, practitioners, and HR professionals.     

RELATIONAL V-CODE CONDITIONS IN A CHILD AND ADOLESCENT POPULATION DO WARRANT TREATMENT

It is often argued that relational V-code conditions are less serious than classical psychiatric disorders, and that they should therefore receive lower clinical priority or diminished levels of treatment funding. Despite these common assertions, there have been virtually no studies that have used actual case data to evaluate whether such problems are in fact less serious and less worthy of treatment funding. We used actual case data from a universally funded child and family clinic to evaluate these questions. Results showed that both classical diagnoses and relational problems were significantly related to markers of clinical severity. As with previous research, family therapy was not differentially associated with a larger number of treatment sessions.     

Transportation Difficulty of Black and White Rural Older Adults

The purpose of this study was to understand self-reported transportation difficulty among rural older adults. We used data from the UAB Study of Aging (255 Black and 259 White), community-dwelling participants residing in rural areas. We examined the relationship of predisposing characteristics, enabling resources, and measures of need for care with self-reports of transportation difficulty. Blacks reported having more transportation difficulty than Whites (24.7% vs. 11.6%; p ≤ .05). When we introduced other variables, race differences disappeared, but there was a race by income interaction with transportation difficulty. Whites with lower incomes were more likely to have transportation difficulty than Whites with higher incomes. When data from Blacks and Whites were analyzed separately, income was the only variable associated with transportation difficulty among Whites. Among Blacks, income was not related to transportation difficulty but several variables other than income (age, gender, marital status, MMSE scores and depression) were.     

Elvira Lyons — A tribute

When I say “you” and “we” I mean both welfare officers and social workers. We should think of a term which covers both groups for we are all in the business of helping people with social problems.     

Questioning Consilience and Autonomy in Self-Determination Theory: A Critique and Hermeneutic-Phenomenological Alternative

This paper offers a theoretical analysis of Self-Determination Theory (SDT) and its claims regarding human autonomy. Self-determination theorists have advanced a form of self-regulated, engaged behavior (i.e., autonomy), founded upon on a consilient account of human motivation that assumes multiple, hierarchical levels of organization and causation (e.g., biological, psychological, and social). Autonomy, from this perspective, is taken to emerge from underlying biological mechanisms, but also able to exert its own causal effects in the world as a unique psychological phenomenon. We contend that in theorizing this way, self-determination theorists have invoked a mixed discourse of mechanism and autonomy that leaves important questions unanswered, perhaps most importantly those concerning how autonomy as a kind of volition can fit coherently in the mechanistic account of world that they advocate. We then offer an alternative perspective based upon the work of various hermeneutic-phenomenological thinkers in philosophy and psychology. This alternative perspective conceptualizes human phenomena such as autonomy and motivation in agentic terms, emphasizing meaningful participation in possibility-laden contexts of everyday practices.     

INCOME UNCERTAINTY and THE ONSET OF THE GREAT DEPRESSION

Income uncertainty contributes substantially to explaining the fall in consumption that marks the onset of the Great Depression. Consistent estimates of the variance of income measure income uncertainty from 1921-30 and are produced using a linear moment model. This series provides a statistical link between the large erratic swings in income uncertainty after September 1929 and the Great Crash in the stock market. Comparison of the behavior of income uncertainty in the 1920s to the pre-World War I and post-World War II eras suggests that the experience after the Great Crash was historically unique.
