Psychometric properties of the French-Canadian version of the Dark Triad Dirty Dozen
No full textThe Dark Triad is a term used to describe a constellation of undesirable personality traits (i.e., Machiavellianism, narcissism, and psychopathy) that have received considerable empirical attention during the past decade. The Dark Triad Dirty Dozen (DTDD) is a concise instrument developed to assess these traits which has shown good psychometric properties. The aim of this study (N = 394) was to translate and validate a French-Canadian adaptation of the Dirty Dozen (DTDD-FC). The DTDD-FC presented (1) good internal consistency and item properties; (2) a bifactor structure (i.e. items loading on each of their respective trait factor as well as with a global factor); (3) conclusive associations with nomological network surrounding each trait (i.e., convergent and discriminant validity coefficients) and social desirability; and (4) sex differences for psychopathy. Overall, the French-Canadian adaptation of the Dirty Dozen seems to be a valid and psychometrically sound measure of the Dark Triad traits, and is comparable to the original English version

A dozen years of Shroud Science Group
No full textFounded in 2002 by Mario Latendresse and coordinated by the author from 2005, the Shroud Science Group on Yahoo! (SSG) is currently a group of 147 scholars mostly from USA, composed of academics, researchers and scholars presenting a remarkable multidisciplinary approach, necessary for Shroud studies.
From 4th of December 2002 to 5th of June 2014, 25763 messages have been exchanged. The SSG analyzed virtually all of the data pertaining to the Turin Shroud (TS), discovering many interesting facts through the various discussions among the members. The most interesting arguments were about the hypothesis of the body image formation and about the flax fabric dating.
The SSG organized an International Conference on the TS and three others have been organized by some of its members who also published more than a dozen papers in international scientific journals and many dozens of papers via conferences, websites, books and other journals. This work describes the most important results published by SSG members
A baker’s dozen of issues facing online academic journal start-ups
No full textThe rapid upsurge in online academic journal creation, publishing, and management has challenged researchers and universities. Much of the recent flurry of activity has happened while guidelines and protocol are being created. This article outlines the nature of the increased publication of these new journals, as well as offers advice in 13 areas that journal editors and boards will face. This article is based on the findings of academics in a wide variety of academic fields, including library science, as well as the author’s own experience as an online journal editor

Author expertise as a function of prior publication count.
No full textExpertise of an author on a given paper is measured by the proportion of subjects (MeSH; a paper typically has a dozen or so terms) on which the author has previously published. Expertise naturally grows with age but never reaches 100% because authors tend to publish on some topics that are new to them.</p
Does the Dark Triad manifest similarly in men and women?: Measurement invariance of the Dirty Dozen across sex
No full textThe Dark Triad is a constellation of three socially undesirable personality traits: narcissism, psychopathy, and Machiavellianism. Previous research has shown that men tend to score higher than women on Dark Triad scales, but the validity of these results is questionable as there is no evidence that the scales used exhibit measurement invariance across sex in the adult population. Here, we report four studies assessing the measurement invariance across sex of a recently developed, concise measure of the Dark Triad, namely Jonason and Webster's (2010) Dirty Dozen (DD). As no validated Italian version of the DD was available, we developed an Italian version and assessed its psychometric properties. Studies 1 to 3 revealed that the Italian DD had adequate psychometric properties, and replicated the three-factor structure and the nomological network of the original version. Study 4 provided evidence of the measurement invariance of the DD across sex, such that men scored higher than women with respect to psychopathy, Machiavellianism, and, to a lesser extent, narcissism. These findings indicate that the DD can be used to provide reliable assessments of sex differences in Dark Triad traits. Furthermore, the results of sex comparisons are consistent with a biosocial approach to social role theory that assumes that being agentic rather than communal is considered desirable for men and undesirable for women
Illustrated C# 2010
No full textThis book presents the C# 2012 language in a uniquely succinct and visual format. Often in programming books, the information can be hidden in a vast sea of words. As a programmer who has over the years used a dozen programming languages, the author understands it can sometimes be difficult to slog through another 1,000-page book of dense text to learn a new language. There are likely many other programmers who feel the same way. To address this situation, this book explains C# 2012 using figures; short, focused code samples; and clear, concise explanations. Figures are of prime importance i
Personality Dark Triad: Portuguese Validation of the Dirty Dozen
No full textIntroductionThe Dark Triad is a term used to describe a constellation of three socially undesirable personality traits: narcissism, psychopathy, and Machiavellianism. Contrary to Altruism (the desire to help others with no personal reward or gain), these traits are harmful to others. Given the increased scientific interest on the dark triad, Jonason and Webster developed a shorter questionnaire to evaluate these three independent-yet-related constructs with only 12 items – Dirty Dozen (D12).ObjectiveTo investigate the psychometric properties of the Portuguese version of the Dirty Dozen.MethodsA community sample composed of 286 university students (69.2% females; mean age = 21.09 ± 2.133; range: 17–33) answered the Portuguese preliminary versions of the Dirty Dozen and of the Altruism dimension from HEXACO-100. To study the temporal stability, 30 participants (66.7% females) answered the D12 again after six weeks.ResultsThe EA Cronbach alpha was “very good” (a = 0.72). Following Kaiser and Cattel Scree Plot criteria, three meaningful factors were extracted which explained variance (EV) was of 54.64%: F1 Machiavellianism (EV 32.07%; a = 0.73), F2 Narcissism (13.665%; a = 0.74), F3 Psychopathy (8.90%; a = 0.64). The test-retest correlation coefficients were high, positive and significant for the total D12 and its dimensions (r > 0.70; P < 0.001). Pearson correlations of D12 total and dimensional scores and Altruism were negative, moderate and significant (r@ − 0.30).ConclusionsThe Portuguese version of Dirty Dozen has good reliability and validity. It could be very useful both in clinical and research contexts, namely in an ongoing project on the relationship between dark triad and perfectionism traits.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec
Structure of Dark Triad Dirty Dozen across eight world regions
No full textThe Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits’ measure—the Dark Triad Dirty Dozen (DTDD)—in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants’ sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD
