In 2002, moderately high levels of modern and old-fashioned racism were documented in a representative sample of 433 students registered in undergraduate courses at a South African university (Pillay & Collings, 2004). In 2006, this survey was replicated using identical methods of data collection and a sample which was representative of university enrolments for 2006 in terms of gender and race: N = 543, gender = 50% female; race = black (40%), Indian (40%), white (17%), colored (3%). Over the four-year period, there was a significant increase in mean item-scores for old-fashioned racism [M = 1.95 vs. 2.15; F(1,971) = 15.16, p < .01], and this finding was supported by a significant study x race interaction, F(3,971) = 6.33, p < .05. Mean item scores increased significantly over time among Indians (2.11 vs. 2.29) but not among blacks (1.74 vs. 1.76), coloreds (2.01 vs. 2.04), or whites (2.33 vs. 2.35). A significant increase in levels of modern racism over the four-year period [M = 2.74 vs. 3.10; F(1,971) = 8.48, p < .01] was indicated by a significant study x race interaction, F(3,971) = 7.31, p < .05, with mean item scores increasing significantly over time among Indians (2.94 vs. 3.62) and whites (3.00 vs. 3.58) but not among blacks (2.04 vs. 2.06) or coloreds (2.47 vs. 2.49). Together these findings suggest that both overt and covert forms of racism persist, with levels of racism varying as a function of racial group membership.

This chapter assesses the analysis and representation of follow-up data. follow-up refers to the process of monitoring persons over time for occurrence of a (set of) prespecified event(s). Practical data collection is often via look-up in registers or databases. The basic requirements for recordings in a follow-up study include date of entry to the study, date of exit from the study, and the status of the person at the exit date. The chapter then explains the likelihood from a follow-up study and why one can analyse rates using Poisson regression. The likelihood contribution from a single person's follow-up can be subdivided in contributions from subintervals of the follow-up. The chapter details the task of splitting the follow-up time along a time-scale. Finally, it considers time-dependent variables.

Over Time

Background: Human milk contains antibodies against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) following Coronavirus Disease 2019 (COVID-19). These antibodies may serve as protection against COVID-19 in infants. However, the evolution of these human milk antibodies over time is unclear. Research Aim: To elucidate the evolution of immunoglobulin A (IgA) against SARS-CoV-2 in human milk after a SARS-CoV-2 infection. Methods: This longitudinal follow-up study included lactating mothers ( N = 24) who had participated in the COVID MILK study. To assess the evolution of SARS-CoV-2 antibodies, serum and human milk samples were collected 14–143 days after the onset of clinical symptoms related to COVID-19. Enzyme-Linked ImmunoSorbent Assay was used to detect antibodies against the ectodomain of the SARS-CoV-2 spike protein. Results: SARS-CoV-2 antibodies remain present up to 5 months (143 days) in human milk after onset of COVID-19 symptoms. Overall, SARS-CoV-2 IgA in human milk seems to gradually decrease over time. Conclusion: Human milk from SARS-CoV-2 convalescent lactating mothers contains specific IgA antibodies against SARS-CoV-2 spike protein up to at least 5 months post-infection. Passive viral immunity can be transferred via human milk and may serve as protection for infants against COVID-19.

Privacy Risks

The growing use of “smart” toys has made it increasingly important to understand the various privacy implications of their use by children and families. The article is a case study of how the risks to young children’s privacy, posed by the commercial data collection of producers of “smart” toys, were represented in the media. Relying on a content analysis of media coverage in twelve European countries and Australia collected during the Christmas season of 2016/2017, and reporting on a follow-up study in selected countries during the Christmas season of 2017/2018, our article illustrates how the issue of children’s privacy risks was dealt with in a superficial manner, leaving relevant stakeholders without substantive information about the issue; and with minimum representation of children’s voices in the coverage itself.

Follow Up Study

BackgroundThe aim was to give estimates of the incidence of different mental disorders from a Finnish prospective epidemiological follow-up study, the UKKI Study.MethodThe original probability sample consisted of 1000 persons, aged 15–64 years. The baseline survey took place in 1969–71, and follow-up surveys were conducted 5 and 16 years after the baseline survey. The research methods included a personal psychiatric interview and data collection from different registers. The diagnostic system was based on the ICD–8 classification.ResultsThe estimated annual incidence of all mental disorders was close to 15 per 1000 both between baseline and the 5-year follow-up as well as between the 5-year and the 16-year follow-up. During the entire 16-year follow-up period the annual incidence of all disorders was 14 per 1000 in men and 17 per 1000 in women. The annual incidence of neurotic disorders was 10 per 1000 in men and 14 per 1000 in women, and that of psychotic disorders 2 per 1000.ConclusionsIn the literature, there are huge differences in the results concerning incidence of mental disorders. The results of the present study were rather close to those of the Swedish Lundby Study, but nowhere near the results of the American ECA Study.

Over Time

The many social changes that have occurred in South Africa since the first democratic elections in 1994 warrant that careful scrutiny be given to the racial attitudes of South Africa's young adults. Their degree of acceptance of the doctrine of deracialisation and reconciliation represents a hope or a warning about the possibility of a stable future. A follow-up study was thus carried out in order to update data collected in 1995, with the hypothesis that, over time, greater acceptance of other racial groups would be reported. In this follow-up study, the authors examined differences among a new sample of 122 Xhosa-speaking Black, 73 so-called coloured, and 234 English-speaking White young adults. Data were collected using a questionnaire that assessed aspects of these groups' perceptions of themselves (identities) and their attitudes toward other racial groups (their prejudice). Statistical significance was found between groups and over time across measures.
