The Role of Language, Parents, and Peers in Ethnic Identity Among Adolescents in Immigrant Families

To construct a model of the influences on ethnic identity among adolescents in immigrant families, we surveyed adolescents and their parents from 81 Armenian families, 47 Vietnamese families, and 88 Mexican families. Adolescents completed measures of ethnic language proficiency, in-group peer social interaction, and ethnic identity. Parents completed a measure of support for cultural maintenance. Across all groups, ethnic language proficiency and in-group peer interaction predicted ethnic identity, and parental cultural maintenance predicted adolescent ethnic language proficiency. However, because of differences among the groups, a separate model was required for each ethnic group. The results suggest both common processes and group differences in the factors that influence ethnic identity.     

Age-at-death estimation based on the study of frontosphenoidal sutures

Determination of age at the time of death based on the observation of cranial sutures has led to numerous studies with sometimes contradictory results. The initial hypothesis being that suture closure is part of an age-related physiological process, the conflicting results have been interpreted by various authors as secondary to the choice of sutures, under the co-existing influence of pathological factors or genetic factors, or even independent of age. Despite these differences, macroscopic methods remain much used in anthropology and in forensic medicine. In our work, we evaluated the value of the degree of closure of the frontosphenoidal suture in estimating age at death of mature subjects, with the secondary objective of establishing a linear regression which could be used in routine practice. The study concerned bone specimens from individuals whose age, sex and medical history were known. Macroscopic observation was carried out on the ectocranial and endocranial sides according to four stages of closure previously defined. 290 sutures were taken from a population of whom two-thirds were men. The method can be repeated and reproduced and the regression established shows the confidence range for average error to be +/-1.5 years. While this result is of interest in terms of precision in prediction for a group of people, the prediction range is too great (+/-23 years) to be applicable to a single individual as part of a forensic procedure.     

Next-Level Friendship

On a hot September night in 1984, I set foot in China for the very first time. After a long wait at Beijing International Airport, I decided, out of sheer despair, to hail a taxi, even though my Chinese was very limited. On the way to the (then) Beijing Institute of Foreign Languages, I started an alarmingly hesitant conversation, more body language than anything, with the driver.     

“Here we give advice for free”: the functioning of plant clinics in Rwanda

Although plant clinics are considered an important mechanism in the service delivery to farmers, not much is known about their functioning in the daily reality of plant doctors and farmer-clients. This article reports on an exploratory study describing the functioning of eight plant clinics in Rwanda. Personal and organisational commitment, publicity, and proactive communication with farmers and local leaders are key factors explaining higher attendance of some clinics. Farmer attendance is under-reported by 40–50%. Data management needs improvement to make clinic records reliable tools for decision-makers. This type of assessment can help improve operations and realise the plant clinics’ potential.     

One-way conversation with Philippe Van Parijs

This essay reacts to Philippe Van Parijs’s arguments in favor of English as the global lingua franca and in favor of the territorial protection of the languages of minority nations. I agree with both arguments. But I see the case for the lingua franca as a matter of convenience rather than justice. And I don’t link territorial protection to the emergence of English, but instead ground it as a fundamental right of national self-determination.
