Relationship between the degree of perineal trauma at vaginal birth and change in haemoglobin concentration

Background

Postpartum anaemia is a problem with high prevalence that significantly affects maternal recovery. Among the causal factors is perineal trauma. However, it is still not known what degree of perineal trauma produces a greater reduction of haemoglobin.

Claudia Jones speaks to “half the world”: gendering Cold War politics in the Daily Worker, 1950–1953

As feminist scholarship has illustrated, historical resurgences of global migration raise questions about the intersections between war politics, persecution of activists, and its gendered implications. Informed by a new historicist approach, this article seeks to contextualize contemporary scholarly conversations on journalism, migration, and feminist studies by conducting a historical analysis of a bi-weekly column entitled “Half the World.” This column was published in the Daily Worker and was written by little-known Caribbean activist and journalist Claudia Jones. A close reading of all printed columns between 1950 and 1953 illustrate that despite Jones’ tendency to reinforce gendered dichotomies of war discourse, where women represented peace and men violence, she also placed women as the creators of a national and transnational movement against US intervention in Korea. Jones’ story, therefore, contributes to previous feminist histories on the role female journalists and activists have played in shaping the relationship between gender, nation, and war politics.     

Children’s Development and Parental Input: Evidence From the UK Millennium Cohort Study

In this study, we use the UK Millennium Cohort Study to estimate a dynamic factor model of child development. Our model follows the children from birth until 7 years of age and allows for both cognitive and noncognitive abilities in children. We find a significant self-productivity effect in both cognitive and noncognitive development, as well as some evidence of dynamic dependence across different abilities. The activities that parents carry out with children at home (parental investment) have a significant effect on children’s development; we find substantial evidence of two distinct latent parental investment variables with differential effects across the two abilities.     

Analyzing Disability in Socially Responsible Companies

The incorporation of People with Disability (PWD) in organizations is a subject taken up by international organizations, such as the European Union and the United Nations, which has had subsequent consequences in Spain with the development of legislation and specific initiatives. In this paper we have considered the concept of disability as part of diversity and, above all, as a fundamental subject of human rights and justice, which has allowed us to include the collective of PWD among the stakeholders of companies. The research on the incorporation of disability as an integral part of the policies of Corporate Social Responsibility (CSR) in companies is very recent, although the term Corporate Social Responsibility and Disability is already used. The main objective of this paper is to analyze the commitment with PWD of Spanish companies considered socially responsible by the sustainability indices used. We have included in four large dimensions (Stakeholders, Visibility, Human Resources and Accessibility) the indicators that have allowed us to analyze the information on PWD published by these companies in their sustainability reports or similar documents accessible through their websites. The results suggest that the companies are more concerned about improving their image towards the exterior than for the commitment with their own employees, which is consistent with the dimension Visibility being where the companies carry out more actions in favor of PWD.     

Note on incidence chromatic number of subquartic graphs

An incidence in a graph G is a pair (v, e) where v is a vertex of G and e is an edge of G incident to v. Two incidences (v, e) and (u, f) are adjacent if at least one of the following holds: \((a) v = u, (b) e = f\), or \((c) vu \in \{e,f\}\). An incidence coloring of G is a coloring of its incidences assigning distinct colors to adjacent incidences. In this note we prove that every subquartic graph admits an incidence coloring with at most seven colors.     

The impact of modular platforms on automobile manufacturing networks

This paper explores the impact on automobile manufacturing networks of adopting modular platforms to replace the standard platforms used to date. Analysis of European manufacturers’ production networks shows that the use of modular architecture improves coordination by increasing manufacturing mobility and thriftiness ability. The changes resulting from this new modular approach also allow manufacturing capacity to be reorganised and overcapacity to be partially eliminated. From the point of view of production systems, the adaptation of manufacturing processes and facilities to this new architecture should aim to increase flexibility by integrating production around a single platform, allowing for different dimensions and for a larger number of models to be produced in a single plant.     

Reference model for implementing ERP systems: an analytical innovation networks perspective

The process for implementing ERP systems is related with the identification of a large range of variables (organisational goals, business rules, business processes, actors, resources and specifics and unique concepts to support these variables). The main agents related to the implementation are the solution supplier, the customer company and the consulting service. If the implementation process is addressed as an organisational innovation, the question is: How to coordinate the ERP implementation resources from an innovation agents network? In order to answer this question, a reference model is proposed for the formation and management of an innovation agent’s network for ERP implementation. The research method is based on a multi-case study for identifying the requirements and to elaborate the reference model applying a modelling method the Enterprise Knowledge Development (EKD). As results, the reference model in an analytical perspective of innovation networks and their drivers, enables to identify, understand and support the process of implementing ERP systems under the EKD models they are: goals; business rules; business processes; actors and resources; concepts; technical components and requirements.     

Subjective well‐being: what do adolescents say?

The aim of this paper is to analyse how 10‐ to 15‐year‐old adolescents define their own perceptions of well‐being and the factors influencing it at their age. Ten focus groups were organized, two from each age group. One group for each age included the students with the lowest scores in subjective well‐being (SWB) and the other included those with the highest, according to their responses to previously administered psychometric scales. The views of the participating adolescents were explored by means of a content analysis. In general, the children mentioned both positive and negative elements of participating in defining what constitutes well‐being. According to these children, well‐being is related to both affects and attitudes, relations with family and friends being key factors in it. Differences in the information provided reveal some variations according to age and SWB score. Children scoring lower in SWB tend to refer more to relationships with friends and basic needs covered, whereas those scoring higher tend to refer more to family relationships and not having problems. The results of this research can contribute to both social policy design and appraisal as they provide an in‐depth understanding of how SWB works at these ages.     

Improving the biomarker diagnostic capacity via functional transformations

The use of the area under the receiver-operating characteristic, ROC, curve (AUC) as an index of diagnostic accuracy is overwhelming in fields such as biomedical science and machine learning. It seems that a larger AUC value has become synonymous with a better performance. The functional transformation of the marker values has been proposed in the specialized literature as a procedure for increasing the AUC and therefore the diagnostic accuracy. However, the classification process is based on some regions (classification subsets) which support the decision made; one subject is classified as positive if its marker is within this region and classified as negative otherwise. In this paper we study the capacity of improving the classification performance of univariate biomarkers via functional transformations and the impact of this transformation on the final classification regions based on a real-world dataset. Particularly, we consider the problem of determining the gender of a subject based on the Mode frequency of his/her voice. The shape of the cumulative distribution function of this characteristic in both the male and the female groups makes the resulting classification problem useful for illustrating the differences between having useful diagnostic rules and obtaining an optimal AUC value. Our point is that improving the AUC by means of a functional transformation can produce classification regions with no practical interpretability. We propose to improve the classification accuracy by making the selection of the classification subsets more flexible while preserving their interpretability. Besides, we provide different graphical approximations which allow us a better understanding of the classification problem.
