The unexpected effect of social status on reproduction: a case study in Joseon Korea from the nineteenth to the twentieth centuries

We examine how parents have made decisions about the number of children they have, given their social status in accordance with residential location (either urban or rural areas) and time (either the pre-modern or modern periods). We use two sets of microdata – Jokbo and Jejeokbu – spanning the early nineteenth to mid-twentieth centuries in Korea. Combining the two data-sets, we use multiple imputation to fill the missing entries of some observations and apply a Poisson regression model on the augmented data. Our empirical results reveal statistically significant evidence that higher socioeconomic status is related to having more children. Additionally, our findings indicate that: (1) all else being constant, among high-status people, rural residents had more children than urban families; (2) for people born between 1800 and 1945, those born closer to the 1940s tended to have fewer children; and (3) during modernization, there was still a significant trend for high-status families to have more children.     

Mighty Morphin’ age progression: how artist,age range,and morphing influences the similarity of forensic age progressions to target individuals

When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.     

Parenthood,child-rearing and fertility in England, 1850–1914

Fertility declines across Europe and the Anglo-world have been explained as the result of reversals of intergenerational flows of wealth. According to this theory, the child was transformed from an economically-useful household asset to an emotionally-valued parental burden. This article is based on a comparative study of changing understandings of parenthood in three provincial English localities between 1850 and 1914. It works from the premise that in order to make sense of reproductive behaviour, it is essential to examine the meanings that men and women attached to childlessness, child-rearing and parenthood.

It is argued that there was not a universal shift that made children into burdens. New understandings of the duties of parenthood did develop, but these were founded on class-, gender- and place-specific interpretations. These encouraged a minority of fathers and mothers to believe that together they had the capacity to improve the lives of their sons and daughters in pioneering ways. Given that husbands and wives had distinct motives for avoiding rearing many children and that the discussion of reproduction was shrouded in silence, the dissemination and use of new ideals of family was crucial in enabling birth control to be thought about respectably within marriage.     

Forensic Facial Comparison: Issues of Admissibility in the Development of Novel Analytical Technique

Much contemporary debate in forensic science concerns validity and admissibility of scientific evidence in court. In this paper, three current approaches to facial identification—image superimposition, photogrammetry, and morphological analysis—are considered with regard to criteria for scientific evidence in the United States, and England, and Wales. The aim of the paper is to assess the extent to which facial image comparison meets criteria of admissibility in these jurisdictions. The method used is a comparative evaluation of the methods of facial image comparison and their underlying premises against the range of admissibility criteria reported in court rulings and relevant judicial and scientific inquiries in the United States and the United Kingdom. While the techniques of facial image comparison are generally accepted within their practitioner communities, they are not tested, and their error rates are unknown. On that basis, the methods of facial image comparison would appear not to meet the anticipated standards. They are, nevertheless, admitted in court in the United States, and England, and Wales. This paper concludes that further research in science and law will be necessary to more definitively establish admissibility of facial image comparison evidence, as it will for other nascent and novel methods that are potentially influential in court proceedings.     

Pronasale Position: An Appraisal of Two Recently Proposed Methods for Predicting Nasal Projection in Facial Reconstruction

This study examines two recently proposed methods for predicting nose projection from the skull, those developed by Stephan et al. (Am J Phys Anthropol 122, 2003, 240) and Rynn et al. (Forensic Sci Med Pathol 6, 2010, 20). A sample of 86 lateral head cephalograms of adult subjects from Central Europe was measured, and the actual and predicted dimensions were compared. Regarding nose projection (the anterior and vertical position of the pronasale), in general, the method of Rynn et al. (Forensic Sci Med Pathol 6, 2010, 20) was found to perform better and with less error variance than the method of Stephan et al. (Am J Phys Anthropol 122, 2003, 240), but the mean difference between the actual and predicted values did not exceed 2.2 mm (6.5% of the actual dimension) in most of the variables tested. The vertical dimensions of the nose were predictable with greater accuracy than the horizontal dimensions. Although the mean error of both methods is not great in practice and thus both methods could be considered to be “accurate,” the real variance of error should not be overlooked.     

Equal reproduction rights? The right to found a family in United Nations’ disability policy since the 1970s

ABSTRACT

With the adoption of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) in 2006, disability as an issue of human rights and international law can no longer be ignored. The history of this convention can be traced back to the 1970s, when disability was framed in United Nations (UN) declarations as a human-rights issue at the global level. One of the recurrent topics of debate during this trajectory was the right of people with disabilities to found a family. This right was far from self-evident and was evaluated very differently by various stakeholders.

This study follows the right to have a family in UN disability policy since the 1970s. The history of the family in relation to disability at the global level has been a neglected field of enquiry compared to other concepts such as gender and race. This study investigates how and why the right to found a family was framed in the Declarations on the Rights of Mentally Disabled Persons (1971) and Disabled Persons (1975), the International Year of Disabled Persons (1981), the International Decade of Disabled Persons (1983 ? 1992), the Standard Rules on the Equalization of Opportunities for Persons with Disabilities (1993) and the UNCRPD in 2006.

The trajectory of the right of people with disabilities to found a family that emerges from these cases shows a change in the 1990s from a social-policy to a human-rights approach towards disability – which reflects a broader trend in global and local histories of human rights. In the case of reproductive rights of people with disabilities this change meant that the emphasis was laid more on providing a legal protection for the individual against the interference of others (so-called negative freedom) than on enhancing the opportunities for disabled people to practice their (positive) freedom.     

Sex,Biological Functions and Social Norms: A Simple Constructivist Theory of Sex

Feminist theory needs a constructivist account of biological sex for at least two reasons. The first is that as long as female and male are the only two sexes that are taken for granted, being cisgender, heterosexual, and preferably a parent will be the norm, and being intersexed, transgender, bi- or homosexual, infertile or voluntarily childless will be deemed failure. The second is the fact that, usually, sex and gender come together in the way that is expected, i.e. the fact that most females are women and most males are men needs to be explained. This paper provides a constructivist theory of sex, which is that the sex categories depend on norms of reproduction. I argue that, because the sex categories are defined according to the two functions or causal roles in reproduction, and biological function is a teleological concept involving purposes, goals, and values, female and male are normative categories. As there are no norms or values in nature, normative categories are social constructions; hence, female and male are not natural but social categories. Once we understand that biological normativity is social, biological norms of heterosexuality, fertility, and so on are no longer incontestable. In addition, as many gender norms also concern reproduction—socially mediated reproduction—this simple theory of sex explains the common confluence of sex and gender.

An accuracy assessment of forensic computerized facial reconstruction employing cone-beam computed tomography from live subjects

The utilization of 3D computerized systems has allowed more effective procedures for forensic facial reconstruction. Three 3D computerized facial reconstructions were produced using skull models from live adult Korean subjects to assess facial morphology prediction accuracy. The 3D skeletal and facial data were recorded from the subjects in an upright position using a cone-beam CT scanner. Shell-to-shell deviation maps were created using 3D surface comparison software, and the deviation errors between the reconstructed and target faces were measured. Results showed that 54%, 65%, and 77% of the three facial reconstruction surfaces had <2.5 mm of error when compared to the relevant target face. The average error for each reconstruction was -0.46 mm (SD = 2.81) for A, -0.31 mm (SD = 2.40) for B, and -0.49 mm (SD = 2.16) for C. The facial features of the reconstructions demonstrated good levels of accuracy compared to the target faces.     

Orthodontic surgery and professional liability: the homozygote twin case

A professional liability lawsuit of an orthodontic case is presented through its medico-legal assessment. The patient underwent an orthodontic treatment combined with several maxillo-facial surgical interventions. Several temporomandibular joint complications followed, plus he was unhappy with aesthetic results and modifications to his facial features. He wanted to verify from a medico-legal point of view the treatment received as he believed something was not done lege artis. The result of the orthodontic assessment was that there were no indications for such surgical interventions, along with other professional negligence: no psychological support given and no indications as to the aesthetic results postsurgery. It was decided to carry out an orthodontic assessment also on his homozygote twin brother, who was discovered to have the same malocclusion. His medico-legal assessment did not substitute the evidence obtained from the deceased, but gave added weight to the final technical conclusion.
