Patterns of genetic and phenotypic variation in Iris haynei and I. atrofusca (Iris sect. Oncocyclus = the royal irises) along an ecogeographical grad…

2002

Iris haynei and I. atrofusca are two closely related narrow endemics distributed vicariously along an ecogeographical north-south gradient in Israel and the West Bank. To obtain baseline information of the taxonomic status, conservation and population history of these taxa, we investigated patterns of phenotypic variation and the partitioning of genetic variation within and among populations using dominant random amplified polymorphic DNA (RAPD) markers. Multivariate (principal components analysis) and taxonomic distance analyses based on morphometric traits from eight populations revealed no unambiguous separation into two distinct groups. Results of genetic analyses for nine populations d…

Social antecedents of the role stress and career-enhancing strategies of newcomers to organizations: A longitudinal study

2003

Newcomers experience uncertainty and stress following entry into an organization. Two features of socialization are important for reducing their stress: socialization tactics and relations with superiors and co-workers. The present study tests a structural equation model, including, first, the effects over time of initial institutional socialization tactics and, second, the association between social relations at the workplace on newcomers’ role stress and career-enhancing strategies, two years later, among a large (N=661) international sample of job and organization stayers. Using LISREL 8.3 the results indicate a good fit between the model and data on several fit indices. Institutional so…

Affinities of European Upper Palaeolithic Homo sapiens and later human evolution

1992

Abstract We investigate the evolutionary affinities of European Upper Palaeolithic populations, using cranial measurements and multivariate techniques. Results indicate that cranial morphology of these populations accords with long-term phyletic trends within Pleistocene hominids. The data indicate an interpretation of differential velocities of change, and results do not support the view that Neanderthals contributed to recent populations.

Les paradoxes de l'emploi féminin sur le pourtour méditérranéen

2012

Cette invitation originale à un voyage sur le pourtour de la Méditerranée permet de mieux appréhender les raisons de la colère des jeunes. L'analyse comparative dans quatorze pays révèle les paradoxes de l'emploi féminin dans des contextes sociaux, démographiques, culturels et économiques, plus ou moins distants, à la lumière de données statistiques les plus récentes. Ces contrées reflètent une image pessimiste : en écho d'une segmentation du marché du travail, le chômage frappe particulièrement la jeunesse, les itinéraires des jeunes femmes ressemblent à un dédale d'incertitudes et de contradictions. Pourtant, certains pays leur offrent davantage d'opportunités.

The stability of sense of coherence: comparing two age groups in a 5-year follow-up study

2003

In the original theoretical formulation, Antonovsky (1987a) proposed that sense of coherence is a developmental construct that becomes stabilized at the age of 30. The present 5-year follow-up study was designed to test this hypothesis by investigating the differences in stability in sense of coherence among two age groups the younger group of which consisted of individuals under and the older group of individuals over 30 years of age. The participants were Finnish technical designers (N=352) of whom 40% (n=141) comprised the younger age group (25–29 years) and 60% (n=211) the older age group (35–40 years). The 13-item Orientation to Life Questionnaire (Antonovsky, 1987a) was used to measur…

Jaffa shared and shattered: contrived coexistence in Israel/Palestine, by Daniel Monterescu

2019

Jaffa means “the beautiful (city)”. Being perhaps the oldest harbour town in the world (or at least one of the oldest), this town and her beauty has always fascinated people. A beautiful old city i...

Transcription of genes in the biosynthetic pathway for fumonisin mycotoxins is epigenetically and differentially regulated in the fungal maize pathog…

2012

ABSTRACT When the fungal pathogen Gibberella moniliformis (anamorph, Fusarium verticillioides ) colonizes maize and maize-based products, it produces class B fumonisin (FB) mycotoxins, which are a significant threat to human and animal health. FB biosynthetic enzymes and accessory proteins are encoded by a set of clustered and cotranscribed genes collectively named FUM, whose molecular regulation is beginning to be unraveled by researchers. FB accumulation correlates with the amount of transcripts from the key FUM genes, FUM1 , FUM21 , and FUM8 . In fungi in general, gene expression is often partially controlled at the chromatin level in secondary metabolism; when this is the case, the deac…

Endocrine disrupter compounds removal in wastewater using microalgae: Degradation kinetics assessment

2018

[EN] This paper describes a study carried out to determine the removal kinetics of four micropollutants (4-tert-octylphenol (OP), technical-nonylphenol (t-NP), 4-nonylphenol (4-NP) and bisphenol-A (BPA)) usually found in wastewater streams. The kinetic experiments were carried out in batch reactors containing the effluent of an Anaerobic Membrane BioReactor (AnMBR) in the presence of light, oxygen and microalgae. As the degradation process of the studied micropollutants obeyed a pseudo-first-order kinetics, the second-order kinetics for each micropollutant was then calculated. The second order rate constants for the hydroxyl radical (k.(OH)) ranged from 7.0.10(+10) to 6.6.10(+12) L.mol(-1).…

Chitin synthetase activity in Candida albicans: subcellular distribution in yeast cells and protoplasts

1991

Chitin synthetase activity was detected in a partly zymogenic form in cell-free homogenates obtained from C. albicans yeast cells and protoplasts of the same type of cells. By isopycnic centrifugation on sucrose gradients of the cell-free homogenates two fractions with chitin synthetase activity were obtained: one was associated with the plasma membrane (labelled with [ 3 H]concanavalin A (con A) and buoyant density 1·195 g ml −1 ) in a partly active state, and the second was in the cytoplasm, where the enzyme was in a particulate fully zymogenic form, lacking affinity to con A. The buoyant density of the enzyme found in this location depended on the method of cell breakage. Lysis of partly…
