We agree with de Jong et al.'s argument that business historians should make their methods more explicit and welcome a more general debate about the most appropriate methods for business historical research. But rather than advocating one ‘new business history’, we argue that contemporary debates about methodology in business history need greater appreciation for the diversity of approaches that have developed in the last decade. And while the hypothesis-testing framework prevalent in the mainstream social sciences favoured by de Jong et al. should have its place among these methodologies, we identify a number of additional streams of research that can legitimately claim to have contributed novel methodological insights by broadening the range of interpretative and qualitative approaches to business history. Thus, we reject privileging a single method, whatever it may be, and argue instead in favour of recognising the plurality of methods being developed and used by business historians – both within their own field and as a basis for interactions with others.

Diagnostic information on children is typically elicited from both children and their parents. The aims of the present paper were to: (1) compare prevalence estimates according to maternal reports, paternal reports and direct interviews of children [major depressive disorder (MDD), anxiety and attention-deficit and disruptive behavioural disorders]; (2) assess mother-child, father-child and inter-parental agreement for these disorders; (3) determine the association between several child, parent and familial characteristics and the degree of diagnostic agreement or the likelihood of parental reporting; (4) determine the predictive validity of diagnostic information provided by parents and children. Analyses were based on 235 mother-offspring, 189 father-offspring and 128 mother-father pairs. Diagnostic assessment included the Kiddie-schedule for Affective Disorders and Schizophrenia (K-SADS) (offspring) and the Diagnostic Interview for Genetic Studies (DIGS) (parents and offspring at follow-up) interviews. Parental reports were collected using the Family History - Research Diagnostic Criteria (FH-RDC). Analyses revealed: (1) prevalence estimates for internalizing disorders were generally lower according to parental information than according to the K-SADS; (2) mother-child and father-child agreement was poor and within similar ranges; (3) parents with a history of MDD or attention deficit hyperactivity disorder (ADHD) reported these disorders in their children more frequently; (4) in a sub-sample followed-up into adulthood, diagnoses of MDD, separation anxiety and conduct disorder at baseline concurred with the corresponding lifetime diagnosis at age 19 according to the child rather than according to the parents. In conclusion, our findings support large discrepancies of diagnostic information provided by parents and children with generally lower reporting of internalizing disorders by parents, and differential reporting of depression and ADHD by parental disease status. Follow-up data also supports the validity of information provided by adolescent offspring.

The study of family history in Parkinson's disease (PD) has resulted in considerable debate over the role of genetic factors in the development of PD. Despite this, family history is consistently identified as an independent risk factor for PD. A multifactorial disease process in which genetic, environmental and lifestyle factors culminate in overall risk seems most likely. This article reviews existing studies of familial aggregation in PD. Recent insights into rare genetic causes of PD have affirmed the importance of ongoing family history research. Future efforts should emphasise well-designed family studies with extensive, non-exclusive phenotyping and ideally long-term follow-up. © 2006 Elsevier Ltd. All rights reserved.

This article seeks to exemplify the extent to which oral life history research can enrich existing historiographies of English Religious Education (RE). Findings are reported from interviews undertaken with a sample of key informants involved in designing and/or implementing significant curriculum changes in RE in the 1960s and 1970s. The interviews provided insights into personal narratives and biographies that have been marginal to, or excluded from, the historical record. Thematic analysis of the oral life histories opened a window into the world of RE, specifically in relation to professional identity and practice, curriculum development, and professional organizations, thereby exposing the operational dynamics of RE at an (inter-)personal and organizational level. The findings are framed by a series of methodological reflections. Overall, oral life histories are shown to be capable of revealing that which was previously hidden and which can be confirmed and contrasted with knowledge gleaned from primary documentary sources.

Questa tesi mira a presentare una panoramica, anche sperimentale con dati editi ed inediti, della ricostruzione delle life histories umane mediante metodi istologici e biogeochimici applicati allo smalto dentale delle dentizioni decidue. La tesi si concentra sulle metodologie biogeochimiche ad alta risoluzione spaziale che consentono di ottenere livelli temporali di dettaglio senza precedenti (da stagionali fino a sub-settimanali), quando combinate con l'analisi istomorfometrica dei tessuti dentali mineralizzati. La presente ricerca si concentra sulla creazione di modelli consistenti di variazione delle concentrazioni di elementi in traccia (con particolare riferimento a stronzio e bario) lungo la giunzione smalto dentinale, ottenuti tramite LA-ICPMS (Laser Ablation Inductively Coupled Mass Spectrometry), in funzione dei cambiamenti nella dieta (allattamento, svezzamento) nel primo anno di età di individui a storia nutrizionale nota (utilizzando denti decidui naturalmente esfoliati). In una prospettiva bioarcheologica, i risultati delle indagini sulla dieta altamente risolte nel tempo e interpretate con modelli come quelli proposti si correlano direttamente alle life histories individuali e consentono una analisi più sfumata e completa del comportamento umano nel passato, fornendo informazioni essenziali per la comprensione degli adattamenti bioculturali e aprendo finestre conoscitive su aspetti quali il rapporto madre-progenie, la gravidanza, l’allattamento, lo stress infantile, la dieta sia della progenie che della madre, la mobilità ad alta risoluzione e molti altri aspetti della vita delle popolazioni del passato che lo studio del DNA antico e della morfologia scheletrica non possono fornire. Dove il DNA antico tace, lo studio avanzato delle life histories parla.
