Back to Gondwanaland: can ancient vicariance explain (some) Indian Ocean disjunct plant distributions?

Oceans, or other wide expanses of inhospitable environment, interrupt present day distributions of many plant groups. Using molecular dating techniques, generally incorporating fossil evidence, we can estimate when such distributions originated. Numerous dating analyses have recently precipitated a paradigm shift in the general explanations for the phenomenon, away from older geological causes, such as continental drift, in favour of more recent, long-distance dispersal (LDD). For example, the 'Gondwanan vicariance' scenario has been dismissed in various studies of Indian Ocean disjunct distributions. We used the gentian tribe Exaceae to reassess this scenario using molecular dating with minimum (fossil), maximum (geological), secondary (from wider analyses) and hypothesis-driven age constraints. Our results indicate that ancient vicariance cannot be ruled out as an explanation for the early origins of Exaceae across Africa, Madagascar and the Indian subcontinent unless a strong assumption is made about the maximum age of Gentianales. However, both the Gondwanan scenario and the available evidence suggest that there were also several, more recent, intercontinental dispersals during the diversification of the group.

A Descriptive Study of Gambling Among Emerging Adult Males in French-Speaking Switzerland.

The aims were twofold: to examine the gambling habits of emerging adult males in the French-speaking regions of Switzerland and to what extent these habits predict problem gambling within this population. We also evaluated problem gambling rates and provided data concerning variables such as gambling location, level of information about problem gambling and awareness of treatment centers. 606 Swiss male conscripts, aged 18-22 years, completed a self-report questionnaire. This was administered during their army recruitment day in 2012. Problem gambling was assessed through the Problem Gambling Severity Index (PGSI) (Ferris and Wynne 2001). 78.5% of the respondents were lifetime gamblers, 56.1% were past-year gamblers. Four out of ten past-year gamblers played in private spaces and in back rooms. The PGSI indicated that 10.8% of past-year gamblers presented with moderate gambling problems, whilst 1.4% appeared to be problem gamblers. The majority of respondents had never received information about problem gambling. Moreover, they were unaware of the existence of treatment centers for problem gambling in their region. PGSI scores were significantly predicted by the variety of games played. Problem gambling rates among young men appear to be higher than those of the general Swiss population. This confirms that emerging adult males are a particularly vulnerable population with regards to gambling addiction. The implications of this are considered for youth gambling-prevention programs.

Representations of work and worker in the three generations of knowledge management. Critical Discourse Analysis of selected texts.

The thesis studies the representations of different elements of contemporary work as present in Knowledge Management (KM). KM is approached as management discourse that is seen to affect and influence managerial practices in organizations. As representatives of KM discourse four journal articles are analyzed, using the methodology of Critical Discourse Analysis and the framework of Critical Management Studies, with a special emphasis on the question of structure and agency. The results of the analysis reveal that structural elements such as information technology and organizational structures are strongly present in the most influential KM representations, making their improvement also a desirable course of action for managers. In contrast agentic properties are not in a central role, they are subjugated to structural constraints of varying kind and degree. The thesis claims that one such constraint is KM discourse itself, influencing managerial and organizational choices and decision making. The thesis concludes that the way human beings are represented, studied and treated in management studies such as KM needs to be re-examined. Pro gradu-tutkielmassa analysoidaan työhön ja sen tekijään liittyviä representaatioita Tietojohtamisen kirjallisuudessa. Tietojohtamista tarkastellaan liikkeenjohdollisena diskurssina, jolla nähdään olevan vaikutus organisaatioiden päätöksentekoon ja toimintaan. Tutkielmassa analysoidaan neljä Tietojohtamisen tieteellistä artikkelia, käyttäen metodina kriittistä diskurssianalyysiä. Tutkielman viitekehyksenä on kriittinen liikkeenjohdon tutkimus. Lisäksi työssä pohditaan kysymystä rakenteen ja toimijan välisestä vuorovaikutuksesta. Tutkielman analyysi paljastaa, että tietojohtamisen vaikutusvaltaisimmat representaatiot painottavat rakenteellisia tekijöitä, kuten informaatioteknologiaa ja organisaatiorakenteita. Tämän seurauksena mm. panostukset em. tekijöihin nähdään organisaatioissa toivottavana toimintana. Vastaavasti representaatiot jotka painottavat yksilöitä ja toimintaa ovat em. tekijöille alisteisessa asemassa. Tapaa, jolla yksilöitä kuvataan ja käsitellään Tietojohtamisen diskurssissa, tulisikin laajentaa ja monipuolistaa.

Dépistage du risque d'allergie et prévention en maternité : enquête des pratiques AllerNaiss [Screening for the risk of allergy and prevention in French maternity units: A survey].

Allergy has been on the rise for half a century and concerns nearly 30% of children; it has now become a real public health problem. The guidelines on prevention of allergy set up by the French Society of Paediatrics (SFP) and the European Society of Paediatric Allergology and Clinical Immunology (ESPACI) are based on screening children at risk through a systematic search of the family history and recommend, for children at risk, exclusive breastfeeding whenever possible or otherwise utilization of hypoallergenic infant formula, which has demonstrated efficacy. The AllerNaiss practice survey assessed the modes of screening and prevention of allergy in French maternity units in 2012. The SFP guidelines are known by 82% of the maternity units that took part in the survey, and the ESPACI guidelines by 55% of them. A screening strategy is in place in 59% of the participating maternity wards, based on local consensus for 36% of them, 13% of the units having a written screening procedure. Screening is based on the search for a history of allergy in first-degree relatives (99%) during pregnancy (51%), in the delivery room (50%), and after delivery (89%). A mode of prevention of the risk of allergy exists in 62% of the maternity units, most often in writing (49%). A hypoallergenic infant formula is prescribed for non-breastfed children in 90% of the units. The survey shows that there is a real need for formalization of allergy risk screening and prevention of allergy in newborns in French maternity units.

Evolving characteristics and outcome of secondary acute promyelocytic leukemia (APL): A prospective analysis by the French-Belgian-Swiss APL group.

BACKGROUND: Reports of patients with secondary acute promyelocytic leukemia (APL) have increased in recent years, particularly for those who received treatment with mitoxantrone, and retrospective studies have suggested that their characteristics and outcomes were similar to those of patients with de novo APL. METHODS: The authors investigated patients with de novo and secondary APL who were included in the ongoing APL-2006 trial. Patients with secondary APL who were included in that trial also were compared with a previous retrospective cohort of patients with secondary APL. RESULTS: In the APL-2006 trial, 42 of 280 patients (15%) had secondary APL. Compared with the retrospective cohort, patients with secondary APL in the APL-2006 trial had a lower incidence of prior breast carcinoma (35.7% vs 57%; P = .03) and a higher incidence of prior prostate carcinoma (26.2% vs 4.7%; P < .001). Treatment of the primary tumor in the APL-2006 trial less frequently included combined radiochemotherapy (28.6% vs 47.2%; P = .044) and no mitoxantrone (0% vs 46.7%; P = .016) but more frequently included anthracyclines (53.3% vs 38.3%; P = .015). In the APL-2006 trial, patients who had secondary APL, compared with those who had de novo APL, were older (mean, 60.2 years vs 48.7 years, respectively; P < .0001) but had a similar complete response rate (97.6% vs 90.3%, respectively), cumulative incidence of relapse (0% vs 1.8%, respectively), and overall survival (92.3% vs 90.9%, respectively) at 18 months. CONCLUSIONS: Although the incidence of secondary APL appears to be stable over time, evolving strategies for the treatment of primary cancers have reduced its occurrence among breast cancer patients but have increased its incidence among patients with prostate cancer. The current results confirm prospectively that patients with secondary APL have characteristics and outcomes similar to those of patients with de novo APL.

Meaning in life and perceived quality of life in Switzerland: results of a representative survey in the German, French and Italian regions.

BACKGROUND: The concept of meaning in life (MIL) has become a central one in recent years, particularly in psycho-oncology and palliative care. The Schedule for Meaning in Life Evaluation (SMILE) has been developed to allow individuals to choose the life areas that they consider to be important for their own MIL. This approach relates to the "World Health Organisation" definition of quality of life (QOL) as an individual's perception of his own position. The aims of this study were (i) to assess MIL in a representative sample of the Swiss population according to the three linguistic regions and (ii) to evaluate whether MIL constitutes a significant determinant of the perceived QOL. METHODS: A telephone survey of the Swiss population, performed by a professional survey company, was conducted between November and December 2013. The interview included the SMILE, perceived QOL (0-10) and health status (1-5), and various sociodemographic variables. In the SMILE, an index of weighting (IOW, 20-100), an index of satisfaction (IOS, 0-100), and a total SMILE index (IOWS, 0-100) are calculated from the areas mentioned by the participants as providing MIL. RESULTS: Among the 6671 telephonic contacts realized, 1015 (15 %) participants completed the survey: 405 French, 400 German and 210 Italian participants. "Family" (80.2 %), "occupation/work" (51 %), and "social relations" (43.3 %) were the most cited MIL-relevant categories. Italian participants listed "health" more frequently than German and French participants (50.4 % vs 31.5 % and 24.8 % respectively, χ(2) = 12.229, p = .002). Age, gender, education, employment, and marital status significantly influenced either the MIL scores or the MIL-relevant categories. Linear regression analyses indicate that 24.3 % of the QOL variance (p = .000) is explained by health status (B = .609, IC = .490-.728, p = .000), MIL (B = .034, IC = .028-.041, p = .000) and socioeconomic status (F = 11.01, p = .000). CONCLUSION: The major finding of our analysis highlights the positive and significant influence of MIL on the perceived QOL in a representative sample of a general, multilingual and multicultural population. This result indicates that the existential dimension is not only determinant for QOL in some critical life events, as shown e.g. in psycho-oncology and palliative care, but also in everyday life.

Apartar y girar los ojos en los textos latinos

This article presents some of the conclusions drawn from our research on eye gestures in Latin texts. This investigation is part of a broader study on gestures in Ancient Rome. We have established a classification of eye gestures that comprises two major categories based on the nature of the gestures: gestures that involve eyelid movements and those that consist of iris movements. This paper focuses on two gestures which belong to this second category: staring and rolling the eyes. We analyse the way these gestures were made, how they were referred to by Roman writers and the meanings that may be inferred from their use in literary texts.

Perceptions of Alzheimer's Disease in the French Population : Evolutions between 2008 and 2013 and Associated Factors in 2013

Abstract: Background. The negative image surrounding AD has a substantial impact on caregiving and on those affected by the disease. Opinion surveys was created as part of the 2008-2012 Alzheimer Plan in France, which included two surveys in general population, at the beginning and at the end. Objective. To evaluate changes of the French population in perceptions, knowledge and beliefs since 5 years and to analyze dimensions with sociodemographics criteria and proximity with AD. Methods. After selection by quota sampling, 2013 French people aged 18 years and over were interviewed by phone in 2008 and 2509 in 2013. Chi-squared tests were carried out to measure the changes between two periods and multivariate logistics regressions were used to assess perceptions. Results. People who cited AD as one of the three most serious diseases increased in 2013 (33.6% versus 26.7% in 2008; p < 0.001). There was no significant change as regards the fear, the sense of being informed and the feeling of embarrassment. Opinions "there are treatments available to improve the wellbeing of patients" and "it is normal to suffer memory loss as you get older" decreased in 2013. Close family carers had a greater sense of the seriousness, a higher risk perception, a better sense of being informed and a greater ease in the presence of a person with AD. Conclusions. The results serve as indicators of the effects of the Alzheimer Plan on French society and testify to the rather weak impact of the Plan on public opinion.
