Will God Make Me Rich? An Investigation into the Relationship between Membership in Charismatic Churches, Wealth, and Women’s Empowerment in Ghana

In recent decades, there has been an explosion in the growth of Pentecostal churches in Ghana, many of which preach that belief in God will translate into material wealth for both men and women. While some have argued that women in these churches are likely to be more empowered due to female leadership and focus on the individual, others have argued that this may not translate to the typical congregant’s experience. After all, members of the Pentecostal church subscribe to the belief that wives should “submit to their husbands” (Biblia n.d.). In this study, I used the 2014 Demographic Health Survey to directly test whether women who identify as Pentecostal/Charismatic/Evangelical have a higher level of empowerment as measured by autonomy in decision making. I found that they exhibit significantly less decision-making power than other Christian women in making big household purchases and on their own healthcare. This exists both before and after controlling for wealth. Thus, the notion that Pentecostal women are more empowered than other Christians appears to be misguided

Reducing behaviour problems in young people through social competence programmes

There is a relatively strong relationship between the concepts of behavioural problems and social competence, in that social competence is regarded as one of the most important protective factors in the prevention of behavioural problems. This paper argues that the concept of social competence should include social skills, social practice and empathic understanding. It identifies the components that form part of an effective social competence programme, including enhancing an understanding of social situations, increasing the generation of adequate social skills, improving the management of provocations which may lead to uncontrolled anger, and developing empathic understanding. The evidence also suggests that effective social competence programmes for children and young people should be multi modal and consist of mixed groups of pupils with and without difficulties. The paper concludes with a brief description of Aggression Replacement Training as an example of a programme which follows the recommended guidelines.peer-reviewe

Food Stamps and Food Insecurity: What Can Be Learned in the Presence of Non-Classical Measurement Error?

Policymakers have been puzzled to observe that food stamp households appear more likely to be food insecure than observationally similar eligible nonparticipating households. We reexamine this issue allowing for nonclassical reporting errors in food stamp participation and food insecurity. Extending the literature on partially identified parameters, we introduce a nonparametric framework that makes transparent what can be known about conditional probabilities when a binary outcome and conditioning variable are both subject to nonclassical measurement error. We find that the food insecurity paradox hinges on strong assumptions about the reliability of the data that are not supported by the previous food stamp participation literature.

Thermal imaging on simulated faults during frictional sliding

Heating during frictional sliding is a major component of the energy budget of earthquakes and represents a potential weakening mechanism. It is therefore important to investigate how heat dissipates during sliding on simulated faults. We present results from laboratory friction experiments where a halite (NaCl) slider held under constant load is dragged across a coarse substrate. Surface evolution and frictional resistance are recorded. Heat emission at the sliding surface is monitored using an infra-red camera. We demonstrate a link between plastic deformations of halite and enhanced heating characterized by transient localized heat spots. When sand 'gouge' is added to the interface, heating is more diffuse. Importantly, when strong asperities concentrate deformation, significantly more heat is produced locally. In natural faults such regions could be nucleation patches for melt production and hence potentially initiate weakening during earthquakes at much smaller sliding velocities or shear stress than previously thought

Normalisation Control in Deep Inference via Atomic Flows

We introduce `atomic flows': they are graphs obtained from derivations by tracing atom occurrences and forgetting the logical structure. We study simple manipulations of atomic flows that correspond to complex reductions on derivations. This allows us to prove, for propositional logic, a new and very general normalisation theorem, which contains cut elimination as a special case. We operate in deep inference, which is more general than other syntactic paradigms, and where normalisation is more difficult to control. We argue that atomic flows are a significant technical advance for normalisation theory, because 1) the technique they support is largely independent of syntax; 2) indeed, it is largely independent of logical inference rules; 3) they constitute a powerful geometric formalism, which is more intuitive than syntax

Zero-G Workstation Design

Zero-g workstations were designed throughout manned spaceflight, based on different criteria and requirements for different programs. The history of design of these workstations is presented along with a thorough evaluation of selected Skylab workstations (the best zero-g experience available on the subject). The results were applied to on-going and future programs, with special emphasis on the correlation of neutral body posture in zero-g to workstation design. Where selected samples of shuttle orbiter workstations are shown as currently designed and compared to experience gained during prior programs in terms of man machine interface design, the evaluations were done in a generic sense to show the methods of applying evaluative techniques

Squares of matrix-product codes

The component-wise or Schur product $C*C'$ of two linear error-correcting codes $C$ and $C'$ over certain finite field is the linear code spanned by all component-wise products of a codeword in $C$ with a codeword in $C'$. When $C=C'$, we call the product the square of $C$ and denote it $C^{*2}$. Motivated by several applications of squares of linear codes in the area of cryptography, in this paper we study squares of so-called matrix-product codes, a general construction that allows to obtain new longer codes from several ``constituent'' codes. We show that in many cases we can relate the square of a matrix-product code to the squares and products of their constituent codes, which allow us to give bounds or even determine its minimum distance. We consider the well-known $(u,u+v)$-construction, or Plotkin sum (which is a special case of a matrix-product code) and determine which parameters we can obtain when the constituent codes are certain cyclic codes. In addition, we use the same techniques to study the squares of other matrix-product codes, for example when the defining matrix is Vandermonde (where the minimum distance is in a certain sense maximal with respect to matrix-product codes).This work is supported by the Danish Council for IndependentResearch: grant DFF-4002-00367, theSpanish Ministry of Economy/FEDER: grant RYC-2016-20208 (AEI/FSE/UE), the Spanish Ministry of Science/FEDER: grant PGC2018-096446-B-C21, and Junta de CyL (Spain): grant VA166G

FINANCIAL RISK IN COTTON PRODUCTION

Risk analysis continues to emphasize price and yield variability as the principal components of the decision-maker's risk environment. This research demonstrates the relative importance of financial risk for a representative cotton farm in Arizona. For highly leveraged operations, financial risk may account for 70 percent of the total risk faced by the producer. Implications for future risk analysis are discussed in light of these findings.Crop Production/Industries, Risk and Uncertainty,
