Repression and Protest Structural Models and Strategic Interactions

The recent wave of upheavals and revolts in Northern Africa and the Middle East goes back to an old question often raised by theories of collective action: does repression act as a negative or positive incentive for further mobilization? Through a review of the vast literature devoted to this question, this article aims to go beyond theoretical and methodological dead-ends. The article moves on to non-Western settings in order to better understand, via a macro-sociological and dynamic approach, the causal effects between mobilizations and repression. It pleads for a meso- and micro-level approach to this issue: an approach that puts analytical emphasis both on protest organizations and on individual activists' careers.

Global alcohol exposure estimates by country, territory and region for 2005--a contribution to the Comparative Risk Assessment for the 2010 Global Burden of Disease Study.

AIMS: This study aimed to estimate the prevalence of life-time abstainers, former drinkers and current drinkers, adult per-capita consumption of alcohol and pattern of drinking scores, by country and Global Burden of Disease region for 2005, and to forecast these indicators for 2010. DESIGN: Statistical modelling based on survey data and routine statistics. SETTING AND PARTICIPANTS: A total of 241 countries and territories. MEASUREMENTS: Per-capita consumption data were obtained with the help of the World Health Organization's Global Information System on Alcohol and Health. Drinking status data were obtained from Gender, Alcohol and Culture: An International Study, the STEPwise approach to Surveillance study, the World Health Survey/Multi-Country Study and other surveys. Consumption and drinking status data were triangulated to estimate alcohol consumption across multiple categories. FINDINGS: In 2005 adult per-capita annual consumption of alcohol was 6.1 litres, with 1.7 litres stemming from unrecorded consumption; 17.1 litres of alcohol were consumed per drinker, 45.8% of all adults were life-time abstainers, 13.6% were former drinkers and 40.6% were current drinkers. Life-time abstention was most prevalent in North Africa/Middle East and South Asia. Eastern Europe and Southern sub-Saharan Africa had the most detrimental pattern of drinking scores, while drinkers in Europe (Eastern and Central) and sub-Saharan Africa (Southern and West) consumed the most alcohol. CONCLUSIONS: Just over 40% of the world's adult population consumes alcohol and the average consumption per drinker is 17.1 litres per year. However, the prevalence of abstention, level of alcohol consumption and patterns of drinking vary widely across regions of the world.

Geographic variation in the frequency of isolation and fluconazole and voriconazole susceptibilities of Candida glabrata: an assessment from the ARTEMIS DISK Global Antifungal Surveillance Program.

Geographic differences in frequency and azole resistance among Candida glabrata may impact empiric antifungal therapy choice. We examined geographic variation in isolation and azole susceptibility of C. glabrata. We examined 23 305 clinical isolates of C. glabrata during ARTEMIS DISK global surveillance. Susceptibility testing to fluconazole and voriconazole was assessed by disk diffusion, and the results were grouped by geographic location: North America (NA) (2470 isolates), Latin America (LA) (2039), Europe (EU) (12 439), Africa and the Middle East (AME) (728), and Asia-Pacific (AP) (5629). Overall, C. glabrata accounted for 11.6% of 201 653 isolates of Candida and varied as a proportion of all Candida isolated from 7.4% in LA to 21.1% in NA. Decreased susceptibility (S) to fluconazole was observed in all geographic regions and ranged from 62.8% in AME to 76.7% in LA. Variation in fluconazole susceptibility was observed within each region: AP (range, 50-100% S), AME (48-86.9%), EU (44.8-88%), LA (43-92%), and NA (74.5-91.6%). Voriconazole was more active than fluconazole (range, 82.3-84.2% S) with similar regional variation. Among 22 sentinel sites participating in ARTEMIS from 2001 through 2007 (84 140 total isolates, 8163 C. glabrata), the frequency of C. glabrata isolation increased in 14 sites and the frequency of fluconazole resistance (R) increased in 11 sites over the 7-year period of study. The sites with the highest cumulative rates of fluconazole R were in Poland (22% R), the Czech Republic (27% R), Venezuela (27% R), and Greece (33% R). C. glabrata was most often isolated from blood, normally sterile body fluids and urine. There is substantial geographic and institutional variation in both frequency of isolation and azole resistance among C. glabrata. Prompt species identification and fluconazole susceptibility testing are necessary to optimize therapy for invasive candidiasis.

ClubMed? Cyclical fluctuations in the Mediterranean basin

We investigate macroeconomic fluctuations in the Mediterranean basin, their similarities and convergence. A model with four indicators, roughly covering theWest, the East and the Middle East and the North Africa portions of theMediterranean, characterizes well the historical experience since the early 1980.Idiosyncratic causes still dominate domestic cyclical fluctuations in many countries. Convergence and divergence coexist are local and transitory. The cyclicaloutlook for the next few years is rosier for the East than for the West.

Spatial variation in the temporal change of male and female melanic ornamentation in the barn owl.

Because the magnitude of selection can vary between sexes and in space and time, sexually antagonistic selection is difficult to demonstrate. In a Swiss population of barn owls (Tyto alba), a heritable eumelanic colour trait (size of black spots on ventral feathers) was positively selected with respect to yearling survival only in females. It remains unclear whether the absence of negative selection in males is typical in this species. To tackle this issue indirectly, we measured the size of black spots in 1733 skin specimens collected by museums from 1816 to 2001 in seven European countries and in the Middle-East. The temporal change in spot size was sex- and country-specific. In males, spots became smaller particularly in three countries (Middle-East, Italy and Switzerland). In females, the size of spots increased significantly in two countries (UK and Spain) and decreased in two others (Germany and Switzerland). Because migration and phenotypic plasticity cannot explain these results, selection is the most likely cause. The weaker temporal change in spot size in females than males may be because of the combined effect of strong genetic correlation between the sexes and stronger negative selection in males than positive selection in females. We thus suggest that in the barn owl, spot size (or genetically correlated traits) is sexually antagonistically selected and that its pattern of selection may account for the maintenance of its variation and sexual dimorphism.

Testimonios arqueológicos del Oriente Próximo reflejados en el Séfer-Masa'ot de Benjamín de Tudela (Siria-Palestina, Mesopotamia y Egipto)

Benjamín de Tudela (en hebreo Biniamín ben rabbí Yonah mi- Tudela) es, sin duda, un navarro universal. Judío de la aljama tudelana, se ignora la fecha de su nacimiento (acaso hacia 1130). Hijo de rabino y viajero infatigable, sólo sabemos de este personaje lo poco que de él se menciona en su famoso Libro de Viajes o Séfer-masa`ot, fruto de sus vivas experiencias -las más de las veces directas- exquisitamente plasmadas en su relación de viaje, redactadas en hebreo. Conocedor del romance navarro vernáculo de la época, sabía hebreo - su lengua de instrucción y cultivo literario- y árabe, entendiendo acaso el griego y el latín.

Methicillin-susceptible Staphylococcus aureus endocarditis isolates are associated with clonal complex 30 genotype and a distinct repertoire of enterotoxins and adhesins.

BACKGROUND: Using multinational collections of methicillin-susceptible Staphylococcus aureus (MSSA) isolates from infective endocarditis (IE) and soft tissue infections (STIs), we sought to (1) validate the finding that S. aureus in clonal complex (CC) 30 is associated with hematogenous complications and (2) test the hypothesis that specific genetic characteristics in S. aureus are associated with infection severity. METHODS: IE and STI isolates from 2 cohorts were frequency matched by geographic origin. Isolates underwent spa typing to infer CC and multiplex polymerase chain reaction for presence of virulence genes. RESULTS: 114 isolate pairs were genotyped. IE isolates were more likely to be CC30 (19.5% vs 6.2%; P = .005) and to contain 3 adhesins (clfB, cna, map/eap; P < .0001 for all) and 5 enterotoxins (tst, sea, sed, see, and sei; P ≤ .005 for all). CC30 isolates were more likely to contain cna, tst, sea, see, seg, and chp (P < .05 for all). CONCLUSIONS: MSSA IE isolates were significantly more likely to be CC30 and to possess a distinct repertoire of virulence genes than MSSA STI isolates from the same region. The genetic basis of this association requires further study.

The future of terrestrial mammals in the Mediterranean basin under climate change.

The Mediterranean basin is considered a hotspot of biological diversity with a long history of modification of natural ecosystems by human activities, and is one of the regions that will face extensive changes in climate. For 181 terrestrial mammals (68% of all Mediterranean mammals), we used an ensemble forecasting approach to model the future (approx. 2100) potential distribution under climate change considering five climate change model outputs for two climate scenarios. Overall, a substantial number of Mediterranean mammals will be severely threatened by future climate change, particularly endemic species. Moreover, we found important changes in potential species richness owing to climate change, with some areas (e.g. montane region in central Italy) gaining species, while most of the region will be losing species (mainly Spain and North Africa). Existing protected areas (PAs) will probably be strongly influenced by climate change, with most PAs in Africa, the Middle East and Spain losing a substantial number of species, and those PAs gaining species (e.g. central Italy and southern France) will experience a substantial shift in species composition.

Retentiojärjestelmän optimointi kartonkikoneella

Diplomityössä tutkittiin kartonkikoneen retentiojärjestelmää ja eri mahdollisuuksia retention ja vedenpoiston tehostamiseen. Tavoitteena oli parantaa etenkin runkokerroksen retentiota ja vedenpoistoa. Työssä testattiin kilpailevan kemikaalitoimittajan mikropartikkelia kartonkikoneella. Lisäksi runkokerroksessa testattiin retentiotärkkelyksen vaikutus kartongin palstaumislujuuteen, suoritettiin käytössä olevan mikropartikkelin annostuksen optimointi sekä testattiin alunan käyttöä retentioainesysteemin tehoaineena. Kirjallisuusosassa tarkasteltiin pinta- ja kolloidikemian perusteita, retentioainejärjestelmiä ja niissä käytettäviä kemikaaleja sekä retentioaineilla tehtävään flokkaukseen vaikuttavia tekijöitä. Laboratoriokokeilla tutkittiin kokeellisessa osassa eri mikropartikkelijärjestelmien toimivuutta kartonkikoneen eri kerroksien massoilla. Toimivimmaksi osoittautuneella mikropartikkelilla suoritettiin pilot-koeajo runkokerroksen massalla. Lisäksi suoritettiin toinen pilot-koeajo, jossa tutkittiin mikropartikkelin vaikutuksia saostuman aiheuttajana. Pilot-koeajoissa saavutettiin samat retentiotasot kuin referenssisysteemillä lähes puolet pienemmällä kemikaalin kulutuksella. Kartongin laatuominaisuuksista huokoisuus, formaatio ja AKD-liiman retentio muuttuivat viiraretention mukaan. Saostumakoeajossa ei todettu retentioaineen vaikuttavan saostumien syntyyn. Täyden mittakaavan koeajossa tarkoituksena oli testata kilpailevan mikropartikkelin toimivuus kartonkikoneella. Koeajossa etsittiin optimaalinen mikropartikkelin annostus eri kerroksiin. Pintakerroksen tuhkaretentio nousi hiukan ja vedenpoisto parani. Runko- ja taustakerroksessa saavutettiin samat retentiotasot sekä vedenpoistot. Samat retentiotasot saavutettiin n. 25 % pienemmällä mikropartikkelin kulutuksella. Kartongin laatuominaisuuksista seurattiin palstautumislujuutta, formaatiota ja AKD-liiman retentoitumista. Kartongin palstautumislujuus heikkeni. Vastaavasti runko- ja taustakerroksen AKD-liiman retentio oli hiukan korkeampi koeajetulla mikropartikkelilla. Formaatiossa ei tapahtunut merkittäviä muutoksia. Jatkokokeet tehtiin kartonkikoneen runkokerroksessa. Kokeissa todettiin retentiotärkkelyksen vaikuttavan kartongin palstautumislujuuteen. Käytössä olevan mikropartikkelin annostelun optimointikokeissa ei saavutettu parannusta retentioon eikä vedenpoistoon. Mikropartikkelilla saavutetaan tietty retentiotaso, jonka jälkeen sillä ei ole enää vaikutusta retentiotasoon. Alunan annostelukokeissa ei alle yksi kg/t annosmäärällä ole vaikutusta retentioon ja vedenpoistoon.

Relationship between diet and reproductive success in the Israeli barn owl

The effect of diet on barn owl (Tyto alba) breeding biology has been well studied in the temperate regions but not in the more arid Middle East. In temperate regions, barn owls are darker colored and mainly prey upon Cricetidae rodents, whereas in arid regions, they are lighter colored and prey to a larger degree upon Muridae rodents. In this study we analyzed the diet and breeding success of 261 barn owl pairs nesting in Israel. The reproductive success of barn owls declined from March to August, and fledged more young when they consumed a larger proportion of social voles (Microtus socialis guentheri). Although the diet of the lighter colored barn owls in Israel comprises more Muridae than that of the darker morphs in temperate regions, in both regions the number of barn owl young increases with an increased proportion of voles in the diet.

Khat (Catha edulis Forsk., Celastraceae) is a flowering perennial shrub with a long history of use and cultivation in East Africa and the Arabian Peninsula. Young khat leaves are traditionally chewed in social gatherings to attain special states of mind, aimed especially at awakeness and enhanced mind focus. Since khat chewing contains amphetamine-like molecules and reponedly causes addiction among users it is banned in most countries, but it is part of social life and legal in some countries. The main phannacoactive compounds present in khat leaves are the phenylpropylamino alkaloids (S) cathinone and (S)-cathine. L-Phenylalan:ine serves as a key biosynthetic precursor of phenylpropylalkaloids. Phenylalanine is converted by a series of not yet fully characterized reactions involving chain-shortening to benzaldehyde, then ligation to decarboxylated pyruvate, oxidation and incorporation of an amino group to yield (S)-cath inone, the most active compound accumulating in young leaves. (S)-Cathinone is subsequently reduced to (S)-cathine, the main compound accumulated in mature leaves, but pharmacologically less active than (S)-cathinone. The pharmacological prospects of khat uses and some personal experiences of one of the authors in khat chewing are described here.

National and Gender Measurement Invariance of the Utrecht-Management of Identity Commitments Scale (U-MICS) : A 10-Nation Study With University Students

The purpose of this study was to examine the psychometric properties of the Utrecht-Management of Identity Commitments Scale (U-MICS), a self-report measure aimed at assessing identity processes of commitment, in-depth exploration, and reconsideration of commitment. We tested its factor structure in university students from a large array of cultural contexts, including 10 nations located in Europe (i.e., Italy, the Netherlands, Poland, Portugal, Romania, and Switzerland), Middle East (i.e., Turkey), and Asia (i.e., China, Japan, and Taiwan). Furthermore, we tested national and gender measurement invariance. Participants were 6,118 (63.2% females) university students aged from 18 to 25 years (Mage = 20.91 years). Results indicated that the three-factor structure of the U-MICS fitted well in the total sample, in each national group, and in gender groups. Furthermore, national and gender measurement invariance were established. Thus, the U-MICS can be fruitfully applied to study identity in university students from various Western and non-Western contexts.
