Le JCR facteur d’impact (IF) et le SCImago Journal Rank Indicator (SJR) des revues françaises : une étude comparative

One of the major functions of academic journals is to contribute to the evaluation of research activities and scientists. Invented more than 50 years ago, the ISI impact factor (IF) became the most important indicator of the quality of journals, in spite of well-known problems and critics such as the over-representation of English-language journals. This is a specific problem for French publishers and scientists; publishing in French is not valorising. Since 2007, the new SCImago Journal Rank Indicator (SJR) offers an alternative to the IF. SJR applies the Google algorithm (PageRank) to the journals of the SCOPUS bibliographic database that indexes more journals than ISI Web of Science. The goal of our study is to compare the two indicators for French academic journals, with three questions: Which is the coverage of French journals by ISI and SCOPUS (title number, scientific disciplines)? Which are the differences of the two indicators IF and SJR for the ranking of French journals? How do they cover the French academic journal publishing market (representativity)? The results of our study of 368 French journals with IF and/or SJR are in favour of the usage of the new indicator, at least as a complement to the IF. (1) Coverage: 166 journals are indexed by ISI (45%), 345 journals are indexed by SCOPUS (94%), 143 journals are indexed by both (39%). 82% of the journals are from STM, 18% are from SS&H. In particular, SCOPUS covers much better the medical and pharmacological sciences. (2) Ranking: The correlation of IF and SJR for the 143 journals with both indicators is high (0.76). The IF better differentiates the journals than the SJR indicator (155 vs. 89 rankings). On the other side, because of the larger source database, more French titles become visible on an international level through SJR than through IF. (3) Representativity: The SJR is more interesting and representative of the French academic journal publishing market than the IF (19% vs. 9%), especially for STM titles (38% vs. 19%), much less for SS&H titles (6% vs. 2%). Nevertheless, ISI (Web of Science) and SCOPUS index journals from only a small part of the French academic publishers (10%–20%). Again, SCOPUS is more representative than the ISI dababase (17% of the publishers vs. 10%). Methodological problems and perspective of a multidimensional evaluation are discussed. Our study compares the ISI impact factor (IF) with the new SJR for 368 French academic journals with IF and/or SJR. The results: The SJR coverage is better than of the IF (94% vs. 45%), especially in medical sciences. The correlation of IF and SJR for journals with both indicators is high (0.76). The IF better differentiates the journals than the SJR indicator (155 vs. 89 rankings). The SJR coverage is more representative of the French academic journal publishing market than ISI/IF (19% vs. 9%), especially for STM titles (38% vs. 19%), less for SS&H titles (6% vs. 2%).     

Attachement père-cadet et qualité des relations fraternelles cadet-aîné

The aim of this study is to establish a link between the father-child attachment and the quality of the sibling relationships for school-age children, by taking into account the theoretical and methodological evolution of this specific attachment. Fifty-seven fathers answered the Questionnaire of Opening up to the World [Défi jeunesse, 8 (2002) 6–12], which defines the father-child attachment (or activation) on two axes: the stimulation (social, cognitive and emotional) and the paternal control exercised over the child. The Questionnaire “Sibling Relationships in Young Children” [Troupel, O., 2006. Attachement fraternel, styles de relations et des interactions de tutelle au sein des fratries de jeunes enfants : effet modulateur de la représentation des relations fraternelles de l’aîné. Thèse de doctorat nouveau régime, université de Toulouse–Le-Mirail] gives insight into the quality of sibships. Children, with a secure attachment to their father, demonstrate a higher level of cooperation with their elder sibling than the other children, in particular those which receive excessive control and little stimulation from their fathers. The hypothesis that the stimulation of the second-born child by the father on the peer side is directly linked to the quality of the sibships is not confirmed. Other results on father-child attachment and sibships are discussed.     

Le vieillissement cognitif et l’hypothèse de l’exercice mental révisée

Although intuitively plausible, the evidence relevant to the mental exercise hypothesis is currently mixed. One of the main controversial issues concerning the investigation of this hypothesis has to do with how cognitive stimulation is assessed. The mental exercise hypothesis was here tested with a subjective and self-reported measure of cognitive stimulation. Overall, results have supported that a greater engagement in cognitively stimulating activities was associated with higher levels of cognitive functioning. However, the rate of cognitive decline with advancing age was not reduced for people who were more mentally active. Of great interest, the subjective measure of cognitive engagement have supported that cognitive demands assessed by participants on activities varied as a function of participants’ cognitive resources: lower cognitive resources were associated with lower perceived cognitive demands.     

Reliability Beyond Theory and Into Practice

The critical reactions of Bentler (2009, doi:), Green and Yang (2009a, doi:; 2009b, doi:), and Revelle and Zinbarg (2009, doi:) to Sijtsma’s (2009, doi:) paper on Cronbach’s alpha are addressed. The dissemination of psychometric knowledge among substantive researchers is discussed.     

Taking Degrees of Truth Seriously

This is a contribution to the discussion on the role of truth degrees in manyvalued logics from the perspective of abstract algebraic logic. It starts with some thoughts on the so-called Suszko’s Thesis (that every logic is two-valued) and on the conception of semantics that underlies it, which includes the truth-preserving notion of consequence. The alternative usage of truth values in order to define logics that preserve degrees of truth is presented and discussed. Some recent works studying these in the particular cases of Łukasiewicz’s many-valued logics and of logics associated with varieties of residuated lattices are also presented. Finally the extension of this paradigm to other, more general situations is discussed, highlighting the need for philosophical or applied motivations in the selection of the truth degrees, due both to the interpretation of the idea of truth degree and to some mathematical difficulties.     

Threat is a Multidimensional Construct: Exploring the Role of Children’s Threat Appraisals in the Relationship Between Interparental Conflict and Child Adjustment

Past research has emphasised the importance of children’s appraisals of the threat posed by parent conflict for understanding links between interparental conflict and child outcomes. However, little is known about what it is that children actually find threatening about parent conflict. Children (n = 236) aged 10–16 years were recruited to examine the relative contribution of four specific threat subtypes—fear of parent conflict escalating, fear of being drawn into parent conflict, fear of parent conflict resulting in family breakdown, and fear of parent conflict disrupting parent/child attachment relationships—in explaining links between interparental conflict and child internalising adjustment. Results showed that children’s worries about being drawn into parent conflict mediated the relationship between interparental conflict and child internalising adjustment. Fear of interparental conflict disrupting parent/child attachment bonds mediated the relationship between interparental conflict and child internalising problems for girls, but not boys. Results are discussed in terms of the importance of considering multiple dimensions of threat for advancing understanding of the processes underlying the interparental conflict/child adjustment relationship.

Anaïs Nin: A case study of personality disorder and creativity

Anaïs Nin, diarist and author of autobiographical novellas and erotica, and gregarious socialite, was known for her exotic persona and stormy personal life. The concept of personality disorder and the underlying assumption of the buffering capacity that personality affords to stressors are discussed. Against this background, evidence drawn from Nin’s diaries, short stories and two biographies suggests that she conformed to the diagnostic criteria of histrionic personality disorder (HPD), with comorbid borderline and narcissistic features, and numerous Axis I symptoms. The proposed origin of the overall dysfunctional histrionic pattern is attributed to her early developmental history, and the maladaptive cognitive mechanisms of dissociation and repression inferred from her writings and shown to conform to the HPD pattern. Finally, it is argued that while Nin may not have displayed the classic divergent cognitive style thought to underlie the association between schizotypy and creativity, her HPD psychopathology was pivotal in shaping her creative products, most famous of which is her diary.     

An evaluation of recollection and familiarity in Alzheimer’s disease and mild cognitive impairment using receiver operating characteristics

There is a need to investigate exactly how memory breaks down in the course of Alzheimer’s disease (AD). Examining what aspects of memorial processing remain relatively intact early in the disease process will allow us to develop behavioral interventions and possible drug therapies focused on these intact processes. Several recent studies have worked to understand the processes of recollection and familiarity in patients with mild cognitive impairment (MCI) and very mild AD. Although there is general agreement that these patient groups are relatively unable to use recollection to support veridical recognition decisions, there has been some question as to how well these patients can use familiarity. The current study used receiver operating characteristic (ROC) curves and a depth of processing manipulation to understand the effect of MCI and AD on the estimates of recollection and familiarity. Results showed that patients with MCI and AD were impaired in both recollection and familiarity, regardless of the depth of encoding. These results are discussed in relation to disease pathology and in the context of recent conflicting evidence as to whether familiarity remains intact in patients with MCI. The authors highlight differences in stimuli type and task difficulty as possibly modulating the ability of these patients to successfully use familiarity in support of memorial decisions.     

Benefits of physical exercise on executive functions in older people with Parkinson’s disease

The benefits of physical exercise on cognitive functioning have been reported in the literature, but the potential benefits to slow the eventual decline in executive functioning (EF) caused by neurodegeneration from Parkinson’s Disease (PD) have rarely been studied. Thus the objective of this study was to analyze the effects of a multimodal physical exercise program on EF in older people with Parkinson’s disease. The EF of the older people was evaluated by neuropsychological testing, and for confounding variables such as attention, depressive symptoms and anxiety, before and after intervention. The 20 participants were assigned into Control (CG) and Trained (TG) Groups. The TG participated in generalized physical training for 6 months. The ANOVA showed a significant interaction (p < .05) that indicated a beneficial contribution of training on EF. No significant interactions were found in the results for confounding variables between groups and pre- and post-intervention, which supports the beneficial findings of physical exercise training on EF.
