Prospective longitudinal data collection is an important way for researchers and evaluators to assess change. In school-based settings, for low-risk and/or likely-beneficial interventions or surveys, data quality and ethical standards are both arguably stronger when using a waiver of parental consent—but doing so often requires the use of anonymous data collection methods. The standard solution to this problem has been the use of a self-generated identification code. However, such codes often incorporate personalized elements (e.g., birth month, middle initial) that, even when meeting the technical standard for anonymity, may raise concerns among both youth participants and their parents, potentially altering willingness to participate, response quality, or generating outrage. There may be value, therefore, in developing a self-generated identification code and matching approach that not only is technically anonymous but also appears anonymous to a research-naive individual. This article provides a proof of concept for a novel matching approach for school-based longitudinal data collection that potentially accomplishes this goal.

Abstract Background Pigmentary keratitis (PK) is commonly recognised in Pugs, but its aetiology is not completely understood. The aim of this study was to determine the prevalence and associated features of PK in Pugs in the United Kingdom (UK). Results A total of 210 Pugs (420 eyes) were recruited from 12 UK dog shows and social events. The median age of Pugs recruited was 2.50 years (range 0.25–16.25 years). Pigmentary keratitis was detected in 369/420 (87.8%) eyes and in at least one eye 193/210 (91.9%) Pugs, of which 17/193 (8.8%) were affected unilaterally and 176/193 (91.2%) bilaterally. Pigmentary keratitis was typically mild to moderate (46.3 and 49.9% of eyes, respectively). Detection of PK was significantly associated with increased age (P = 0.002) and the presence of medial entropion of the lower eyelid (MELE) (P = 0.001). Severity of PK was significantly associated with the grade of MELE (P < 0.001). There was also a correlation between the presence of limbal pigment and PK (P = 0.036) that warrants further study. Conclusions This study estimated a high disease prevalence of PK in UK Pugs, and demonstrated significant associations with age and the presence of MELE. These associations, which have not been previously reported, offer an insight into the underlying pathophysiology of this condition in Pugs. The results encourage further population research, such as prospective longitudinal studies. These findings also support the development of clinical and breeding strategies based on the reduction of MELE and, possibly, limbal pigment.

This chapter focuses on formally representing life cycle semantics of part-whole relations in conceptual data models by utilizing the temporal modality. The authors approach this by resorting to the temporal conceptual data modeling language ERVT and extend it with the novel notion of status relations. This enables a precise axiomatization of the constraints for essential parts and wholes compared to mandatory parts and wholes, as well as introduction of temporally suspended part-whole relations. To facilitate usage in the conceptual stage, a set of closed questions and decision diagram are proposed. The longterm objectives are to ascertain which type of shareability and which lifetime aspects are possible for part-whole relations, investigate the formal semantics for sharability, and how to model these kind of differences in conceptual data models.

This paper outlines briefly the historical development of ideas related to longitudinal studies and their advantages over cross-sectional studies. Then it points out a few complicating factors that arise with the analysis of longitudinal data and highlights some of the approaches adopted to manage those complicating factors and illustrated in the papers included in this Special Issue. The overall aim is to promote a better understanding of the information that longitudinal data provide and of the suitable techniques needed to analyze such data.

AbstractMaternal depression is associated with adverse child outcomes including antisocial behaviour (ASB). Prospective longitudinal studies have focused on the timing and cumulative exposure to maternal depression to further delineate the association and mechanisms of effect. The objective of this systematic review was to synthesise and evaluate the findings of longitudinal studies of maternal depression and offspring antisocial behaviour. Three databases were searched (Psychinfo, Web of Science, and Medline). Twenty of 5936 studies met inclusion criteria. Study quality was assessed using the Critical Appraisal Skills Programme criteria [Critical Appraisal Skills Programme (2017) CASP (cohort observation checklist). https://casp-uk.net/wpcontent/uploads/2018/01/CASP-Cohort-Study-Checklist.pdf]. Results of individual studies were highly varied, using diverse analytical approaches and not all studies explored the independent effects of different episodes. Only three studies examined hypothesised mechanisms. Prenatal, postnatal, and later episodes of depression were all predictive of antisocial outcomes. One particular time period of depression exposure did not emerge as more predictive of offspring ASB than another. However, measures of maternal depression after the perinatal period were limited and typically included a one-off assessment of mothers’ depressive symptoms that was concurrent to the assessment of offspring ASB. When cumulative exposure to maternal depression and specific timing effects were measured within the same study it was cumulative exposure that conferred the greatest risk for offspring ASB—particularly when this exposure began during the perinatal period. Findings are discussed in terms of limitations in the literature and highlight the need for future research to examine the biological and environmental mechanisms that underpin associations between maternal depression and offspring antisocial behaviour during different stages of development.
