Urban art as platforms for bodily engagement and social encounters: the Modified Social Benches

Abstract

This paper discusses the role of the Modified Social Benches, a series of urban artworks, as platforms for bodily engagement and social encounters in open, outdoor urban spaces. Special attention is given to a couple of salient aspects involving both the design of the artworks and their social appropriation: (a) the different levels of sensory and kinesthetic engagement afforded by the benches, and (b) how these material qualities reflect in the urban space around the benches, lending the artworks a notorious social character. The social and the bodily dimensions are presented as intertwined characteristics of the Modified Social Benches. In order to explore these relationships, the paper highlights a set of key concepts, such as social encounters and affordances, as well as the notions of performance and engagement.     

Extensions of stability selection using subsamples of observations and covariates

We introduce extensions of stability selection, a method to stabilise variable selection methods introduced by Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010). We propose to apply a base selection method repeatedly to random subsamples of observations and subsets of covariates under scrutiny, and to select covariates based on their selection frequency. We analyse the effects and benefits of these extensions. Our analysis generalizes the theoretical results of Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010) from the case of half-samples to subsamples of arbitrary size. We study, in a theoretical manner, the effect of taking random covariate subsets using a simplified score model. Finally we validate these extensions on numerical experiments on both synthetic and real datasets, and compare the obtained results in detail to the original stability selection method.     

Prevalence estimates and correlates of elder abuse in the United States: The National Intimate Partner and Sexual Violence Survey

This study examines the prevalence and correlates of psychological abuse and physical abuse against women and men aged 70 or older. Self-report data from 2,185 respondents in the 2010 National Intimate Partner and Sexual Violence Survey (NISVS) were used to create weighted estimates for past-year experiences of abuse. Correlates were then examined using survey logistic regression models. More than 1 in 10 adults who are 70 years of age or older (14.0%) have experienced some form of abuse in the past year, with 12.1% experiencing psychological abuse and 1.7% experiencing physical abuse. One in five victims (20.8%) were abused by both intimate and nonintimate partners. Health care insecurity was the strongest correlate of past-year abuse. The odds of experiencing abuse were 4.53 times greater for those who experienced health care insecurity than for those who did not. This presents a significant challenge for identifying and helping victims of abuse.     

Drivers of land use change and household determinants of sustainability in smallholder farming systems of Eastern Uganda

Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding of the drivers that have led to changes in land use in these systems and factors that influence the systems’ sustainability is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems in eastern Uganda from 1960 to 2001 in a place-based analysis combined with a comparative analysis of similar low input systems in southern Mali. This study showed that policy-institutional factors next to population growth have driven land use changes in the Teso systems, and that nutrient balances of farm households are useful indicators to identify their sustainability. During the period of analysis, the fraction of land under cultivation increased from 46 to 78%, and communal grazing lands nearly completely disappeared. Cropping diversified over time; cassava overtook cotton and millet in importance, and rice emerged as an alternative cash crop. Impacts of political instability, such as the collapse of cotton marketing and land management institutions, of communal labour arrangements and aggravation of cattle rustling were linked to the changes. Crop productivity in the farming systems is poor and nutrient balances differed between farm types. Balances of N, P and K were all positive for larger farms (LF) that had more cattle and derived a larger proportion of their income from off-farm activities, whereas on the medium farms (MF), small farms with cattle (SF1) and without cattle (SF2) balances were mostly negative. Sustainability of the farming system is driven by livestock, crop production, labour and access to off-farm income. Building private public partnerships around market-oriented crops can be an entry point for encouraging investment in use of external nutrient inputs to boost productivity in such African farming systems. However, intervention strategies should recognise the diversity and heterogeneity between farms to ensure efficient use of these external inputs.

Assessing the impact of measurement error in modeling change in the absence of auxiliary data

Measurement error is well known to cause bias in estimated regression coefficients and a loss of power for detecting associations. Methods commonly used to correct for bias often require auxiliary data. We develop a solution for investigating associations between the change in an imprecisely measured outcome and precisely measured predictors, adjusting for the baseline value of the outcome when auxiliary data are not available. We require the specification of ranges for the reliability or the measurement error variance. The solution allows one to investigate the associations for change and to assess the impact of the measurement error.     

Sustainability reporting patterns of companies listed on the Johannesburg securities exchange

The demand by stakeholders for information about companies’ social and environmental performance has led to sustainability reporting becoming essential. The Global Reporting Initiative (GRI) guidelines are the international reporting standard whereas the Johannesburg Securities Exchange Socially Responsible Investment (JSE SRI) Index guidelines are used in South Africa. Although South Africa is regarded as one of the leaders in sustainability reporting in the world, the JSE SRI Index is still a relatively new standard and its efficiency will only be proved over time. The research on which this paper is based, determined whether reporting patterns exist across specific market sectors of the sustainability reports of companies listed on the JSE in order to establish if the JSE SRI Index guidelines on reporting are efficient. Results indicated that all the selected market sectors reported on the environment, society and governance (ESG) categories as per requirements of the JSE SRI Index. The mining and materials sector reported more in the environment and the society categories than the other sectors, while in the governance category less reporting on indirect impacts by all the sectors was noted. The implication of this is that in general, companies find the JSE SRI Index guidelines on reporting easy to implement. However, less reporting of companies’ indirect impacts on their operating environments could mean that there is still a lack of completeness and transparency from the companies’ reports, which could be as a result of a lack of firmer guidelines by the JSE SRI Index guidelines on reporting of such issues.     

Correlation between pelvic floor strength and physical activity level in healthy men

The male pelvic floor muscles comprise a pair of compound muscle layers referred to as the levator ani. Studies have shown that pelvic floor muscle strength is affected by physical activity. This study aimed to assess male pelvic floor muscle strength through manometry of the external anal sphincter and evaluation of its association with physical activity level, BMI, and rectal pressure in healthy men. To assess physical activity level over the previous week, we used the International Physical Activity Questionnaire 8 (IPAQ). Pelvic floor muscle strength was assessed via anorectal manometry. The results shows a negative correlation between resting pressure and MET, a positive correlation between rectal pressure and resting and maximum pressure. The novel finding of this study is a negative correlation between walking and pelvic floor strength. This study raises new questions about the understanding of the interaction among physical activity, intraabdominal pressure, and pelvic floor strength in the physiology of continence in men.
