Measurement and structural invariance of the US version of the Birth Satisfaction Scale-Revised (BSS-R) in a large sample

Background

The 10-item Birth Satisfaction Scale-Revised (BSS-R) is being increasingly used internationally. The use of the measure and the concept has gathered traction in the United States following the development of a US version of the tool. A limitation of previous studies of the measurement characteristics of the BSS-R is modest sample size. Unplanned pregnancy is recognised as being associated with a range of negative birth outcomes, but the relationship to birth satisfaction has received little attention, despite the importance of birth satisfaction to a range of postnatal outcomes.

Robust adaptive Lasso for variable selection

The adaptive least absolute shrinkage and selection operator (Lasso) and least absolute deviation (LAD)-Lasso are two attractive shrinkage methods for simultaneous variable selection and regression parameter estimation. While the adaptive Lasso is efficient for small magnitude errors, LAD-Lasso is robust against heavy-tailed errors and severe outliers. In this article, we consider a data-driven convex combination of these two modern procedures to produce a robust adaptive Lasso, which not only enjoys the oracle properties, but synthesizes the advantages of the adaptive Lasso and LAD-Lasso. It fully adapts to different error structures including the infinite variance case and automatically chooses the optimal weight to achieve both robustness and high efficiency. Extensive simulation studies demonstrate a good finite sample performance of the robust adaptive Lasso. Two data sets are analyzed to illustrate the practical use of the procedure.     

Feasibility and Acceptability of Smartphone Assessment in Older Adults with Cognitive and Emotional Difficulties

This feasibility study assessed perceived acceptability, adherence rates, and reasons for nonadherence to smartphone-based ecological momentary assessment (EMA). At two sites, participants (n = 103) ages 65 years or older with diagnosed anxiety or depressive disorder and cognitive concerns responded three times daily to smartphone-based EMA questions assessing clinical outcomes for two 10-day periods. Quantitative and qualitative measures followed both 10-day EMA periods. Overall, 76% of participants completed surveys on ≥ 10 of the 20 assessment days, and 70% of participants completed at least 30% of the total surveys. Reasons for nonadherence included technical, logistical, physiological, and cognitive issues. Smartphone-based EMA is feasible in older adults with cognitive and emotional difficulties. EMA tools should be responsive to the needs and preferences of participants to ensure adequate acceptability and adherence in this population. Our findings can inform the design, development, and implementation of mobile technologies in older adults in research and clinical contexts.     

Voting and the Scottish referendum: perspectives of people with intellectual disabilities and their family and paid carers

Voting is a human right for every citizen yet many people with intellectual disabilities do not vote or have little support to exercise their right to vote. This article explores views on the wider aspects of voting against the backdrop of the Scottish referendum using focus groups involving people with intellectual disabilities (n = 12), family carers (n = 7) and paid carers (n = 5). Findings revealed that people with intellectual disabilities had similar concerns to the general population about the referendum. Regarding voting, all groups identified the need to discuss issues and for practical support and accessible information to ensure informed choices were made when voting.     

Reporting Child Sexual Abuse within Religious Settings: Challenges and Future Directions

The sexual abuse of children within religious settings is an issue that has gained increased popular and professional attention over the past two decades. Various reports have highlighted the scale of such abuse, along with shortcomings in reporting practices. In this article, we outline some contemporary research that sought to understand the psychology that underpins variable reporting practices. In line with this research, we set out two conceptual frameworks that have some potential to help to explain such practices: system justification theory and moral foundations theory. Further, we describe how these frameworks could be adopted in research moving forward in order to make sense of the ways in which members of religious groups respond to allegations of child sexual abuse within their institutions. We close the article by arguing that by gaining a deeper understanding of the psychology underlying reporting practices, it may be possible to communicate more effectively about child sexual abuse within religious institutions, and therefore encourage more widespread reporting of allegations before more children are harmed.

‘We outline some contemporary research that sought to understand the psychology that underpins variable reporting practices’

Key Practitioner Messages

• Those most likely to observe or suspect child abuse in religious settings are themselves likely to participate in such settings.
• The challenge for these ‘onlookers’ is to overcome the psychological dynamics that push against the recognition and reporting of child abuse in religious settings.
• These dynamics can be understood via established psychological theories and frameworks.
• Practitioners concerned with improving reporting practice in these contexts can draw on this work to inform training and intervention strategies.

     

Floral morphology as the main driver of flower-feeding insect occurrences in the Paris region

Through the rapid expansion worldwide of impervious areas and habitat fragmentation, urbanization has strong consequences that must be understood to efficiently manage biodiversity. We studied the effects of urbanization on flower-feeding insects by using data from a citizen science program in the Parisian region. We analysed the occurrence of insects from 46 different families on flowers of different morphologies, using landscape indices in buffer areas from a 100-m to a 4000-m radius around 1194 sampled sites. Our aims were to determine (i) how the proportion of impervious area around sampled sites affected the occurrence of flower-feeding insect families and at which landscape scales impervious area calculations best predicted these occurrences; (ii) the effect of corolla shape variables on insect family occurrences. Twenty-one families were negatively impacted by increasing proportion of impervious areas (urbanophobic) and 3 were positively impacted (urbanophilic). Urbanophobic families were most affected by the proportion of impervious areas when it was estimated within buffers of 200-m to 1400-m radii, depending on the family. Notable losses of urbanophobic families were detected at less than 50% of impervious areas, which highlights the threat to the diversity of flower-feeding insects posed by urban sprawl. Corolla shape variables were the variables most often significantly implicated in the occurrence of insect families. Urbanophobic families were negatively affected by the tubular shape of flowers, and tubular corollas were found more often in urbanized areas. These results suggest that flora management might be a key component for the conservation of insect diversity in cities.     

Language educators’ regard for variation in late modernity: Perceptions of linguistic variation in minority contexts

This article investigates language educators’ regard for linguistic variation in a minority language context. It argues that teachers function as language norm authorities who may influence the linguistic practices and ideologies of students, and that this role takes on added significance in minority language contexts where access to the target language may be limited. Data are presented from a study on the linguistic ideologies of Irish language educators – ‘new speakers’ who acquired the language mainly thorough the education system. Participants’ ideologies on variation in modern spoken Irish were explored using semi‐structured interviews incorporating a speaker evaluation design. Although participants valorise traditional dialectal varieties of Irish, in line with established hierarchies, ideological frameworks are contested so that new ways of using Irish are beginning to gain overt acceptance. The results reveal the manner in which hierarchies of language variation in the Irish language are in flux in our contemporary late‐modern period.     

Imaging convex quadrilateral inclusions in uniform conductors from electrical boundary measurements

We demonstrate simulation-based Bayesian imaging from electrical impedance tomographic data, by summarizing the set of conductance images which could give rise to the data. The forward map from conductance image to data requires the solution of a partial differential equation subject to boundary conditions. We develop the example of recovering an unknown convex polygonal insulating inclusion within an object made of otherwise uniformly conducting material, and illustrate our methods with noisy synthetic data. Sampling is carried out using Markov chain Monte Carlo with the efficiency of the algorithm investigated over a range of noise levels.     

Delay Discounting and Probability Discounting,But Not Response Inhibition,Are Associated With Sexual Risk Taking in Adults

Sexual risk behavior (SRB) is associated with impulsivity, but it is not clear whether different aspects of impulsivity are uniquely related to SRBs in adults. Unmarried adults ages 18 to 30 (N = 296; 41.0% male) recruited from the community reported their frequency of SRBs over the past six months using the Sexual Risk Survey (SRS; Turchik & Garske, 2009) and completed three behavioral measures of impulsivity: insensitivity to delayed consequences (delay discounting [DD]), insensitivity to probabilistic consequences (probability discounting [PD]) and response inhibition (stop signal task [SST]). SRS total scores were significantly related to both DD and PD but not SST. These findings suggest that insensitivity to delayed and probabilistic consequences, but not response inhibition, are meaningfully associated with SRBs in young adults. This may be important for the development of strategies to prevent or reduce sexual risk behaviors.     

CORPORATE TAX POLICY AND INDUSTRY LOCATION WITH FULLY ENDOGENOUS PRODUCTIVITY GROWTH

This paper considers how national corporate tax policy affects productivity growth through adjustments in geographic patterns of industry in a two‐country model of trade. With trade costs and imperfect knowledge spillovers between countries, production concentrates partially and innovation concentrates fully in the country with the lowest tax rate. A rise in the international corporate tax differential accelerates productivity growth through an increase in the production share of the low‐tax country that improves knowledge spillovers from industry to innovation. The paper also investigates the relationship between the corporate tax differential and the level of market entry, and analytically characterizes the effects of changes in tax policy on national welfare.
