Old age protection of flexible workers in Belgium Old age protection of flexible workers in Belgium This article investigates to what extent the Belgian pension system is adapted to the proliferation of a-typical forms of employment. Are there any differences between the old age protection of flexible and non-flexible workers? What are the effects of flexible employment on participation in the three pension pillars and on the level of pension benefits? To answer these questions, the article pursues a double research strategy: an analysis of Belgian legislation and relevant collective labour agreements is complemented with a statistical analysis on the Panel Study of Belgian Households (PSBH). The analyses show that part-time employment results in a lower pension, while other forms of temporal flexibility such as temporary leave arrangements and temporary unemployment do not. In the second pillar we find that contractual and transitional flexible workers are discriminated. Finally, the results indicate that flexible workers do not compensate for lower pension protection through increased participation in the third pension pillar. Our findings suggest that a re-assessment of the system of ‘assimilated’ periods is required, as well as the development of a system of coordinated regulation for the three pension pillars.

Functional and structural damages of tubulointerstitium are caused by proteinuria. The aim of this study was to assess the influence of different proteinuria levels on Na+, K+, Cl tubular transport. We examined 50 patients (24 males, 26 females), mean age 46.50 ? 13.08 years, with mean creati-nine clearence of 87.29 ? 31.17 mL/min. They were separated in three groups depending on proteinuria value. The first group with proteinuria less than 0.3 g/24h included 19 persons (7 males, 12 females), mean age 45.12 ? 13.28 years, with mean creatinine clearance of 94.27 ? 34.70 mL/min. The second group of 18 patients (8 males, 10 females), mean age 45.39 ? 12.64 years had proteinuria of 0.3-3,0 g/24h and mean creatinine clearance of 90.07 ? 31.89 mL/min. The third group had proteinuria level higher than 3.0g/24h and mean creatinine clearance of 73.25 ? 20.44 mL/min. It included 13 patients (9 males, 4 females), mean age 50.08 ? 13.73 years. As a parameter of proteinuria influence on tubular transport of Na+, K+ and Cl-, fractional excretion of these electrolytes, was studied. Student's T test, Mann Whitney U test and c2 test were used for statistical analysis. No statistically significant influence of proteinuria was found on Na+, K+ and Cl tubular transport.

State Responses

What explains state responses to the refugees they receive? This book identifies two puzzling patterns: states open their borders to some refugee groups while blocking others (discrimination), and a number of countries have given the United Nations (UN) control of asylum procedures and refugee camps on their territory (delegation). To explain this selective exercise of sovereignty, the book develops a two-part theoretical framework in which policymakers in refugee-receiving countries weigh international and domestic concerns. Internationally, leaders use refugees to reassure allies and exert pressure on rivals. Domestically, policymakers have incentives to favor those refugee groups with whom they share an ethnic identity. When these international and domestic incentives conflict, shifting responsibility to the UN allows policymakers to placate both refugee-sending countries and domestic constituencies. The book then carries out a “three-stage, multi-level” research design in which each successive step corroborates and elaborates the findings of the preceding stage. The first stage involves statistical analysis of asylum admissions worldwide. The second stage presents two country case studies: Egypt (a country that is broadly representative of most refugee recipients) and Turkey (an outlier that has limited the geographic application of the Refugee Convention). The third stage zooms in on sub- or within-country dynamics in Kenya (home to one of the largest refugee populations in the world) through content analysis of parliamentary proceedings. Studying state responses to refugees is instructive because it can help explain why states sometimes assert, and at other times cede, their sovereignty in the face of refugee rights.

The resistance of Chinese asters to <I>Fusarium</I> wilt was tested by artificially inoculating the root systems. A mixture of <I>Fusarium</I> isolates was prepared with a concentration of about 10<sup>4</sup>–10<sup>9</sup> propagules per litre of the pathogen. 63 cultivars of both domestic and foreign origin were evaluated in the 1<sup>st</sup> year, 95 in the 2<sup>nd</sup> year and 89 in the 3<sup>rd</sup> year. Clear, statistically valid differences in mortality, both with experiments involving artificial inoculations and considering natural infections, make it possible to divide aster varieties into three groups based in their resistance to infections. The first set can be described as resistant. This includes the Matsumoto, Einf. Madeleine and Americká kráska series, and several others. The second set can be described as being moderately resistant. This includes the Chryzantémokvěté and Standy series, and the cultivars Matsumoto Pink, Princes Armida and Jitka. The third set can be described as sensitive. This includes the Průhonický trpaslík, Jehlicovité and Pastel series and several others. A statistical analysis of the results shows that the Einf. Madeleine series of cultivars is the most resistant to <I>Fusarium</I> wilt. This series is phenotypically similar to the original botanical species. Resistance was evaluated by recording the differences in mortality rates between artificially-inoculated plants and non-inoculated group (controls).

SummaryAn international collaborative study involving 20 laboratories was undertaken to evaluate the status of standardization of a commerical recombinant thromboplastin. The results show that the reagent fulfills the WHO requirements for thromboplastin calibration against two International Reference Preparations (IRP) from different species, because there was a linear relationship of log-transformed prothrombin times as measured by the recombinant reagent and the two IRPs in normal individuals and patients stabilized on oral anticoagulants. The regression lines drawn through the patient data points passed through the normal data points in the majority of instances. The average ISI values for three different batches were close to unity. On the average, the ISI value calculated against BCT/253 (human, plain) was slightly smaller than that against RBT/79 (rabbit, plain). The between laboratory precision of calibration (CV = 5-6%) did not change whether BCT/253 or RBT/79 was used, whereas it was substantially improved when the calibrations of batches 2 and 3 were performed against batch 1, arbitrarily taken as standard (CV ≤ 1.7%). Statistical analysis to test for differences between slopes revealed no significant between-batch differences in 16 of 20 laboratories. However slight differences for the third batch (2.8% less than the average ISI value of batches 1 and 2) leave room for further improvement in the standardization of the reagent.

Activity of Monoamine Oxidases in Rat Female Genital Organs During Preimplantation Period of PregnancyOur objectives in the present study were to determine the activity of monoamine oxidases A and B (MAO AB) in rat ovary, oviduct and uterus during preimplantation period of pregnancy. It should help us to clarify and better understand possible involvement of both MAO enzymes in the reproductive process. Pregnant females were killed employing a lethal dose of thiopental on the first (D1), on the third (D3), and on the fifth (D5) days of pregnancy. Rats were perfused transcardially with the PBS to rinse out of the body as much blood as possible. Ovaries, oviducts and uteri were immediately removed and stored until the measurement was done. MAO activity was determined by fluorescent monoamine oxidase detection kit. In the ovaries we have found the highest MAO activity at D3, followed by D1, and the lowest levels were recorded at D5 of pregnancy. In the oviducts, the highest MAO activity was detected again at D3, followed by D5, and by D1 of pregnancy. But statistical analysis did not reveal any difference between individual days of pregnancy nor in the ovaries, neither in uterine tubes. Uteri were the only organs, in which statistically significant differences were detected (p<0.001). The highest activity of MAO was observed at D5, followed by D1, and by D3 of pregnancy. Potential mechanisms responsible for the changed MAO activity in gonads during preimplantation period of pregnancy are proposed.

The geometrical morphometry represents a modern method of statistical analysis of objects’ morphology. The article is dedicated to discussion of opportunities and limitations of geometrical morphometry methods for study of earthenware shapes. The article deals with three examples of geometrical morphometry use for analysis of vessel shapes study in solving research problems of various complexity. Every of these examples differs in amount of known source data on objects of study. In the first example results of analysis of two types of early Byzantine amphorae forms are considered. By dint of geometrical morphometry it became possible to establish legitimacy of these types detachment and to explain that the principal differences between these types consist in the general proportionality of vessels. In the second example 252 shapes of vessels from the Balanovo burial ground of the Bronze Age are analyzed. An attempt is undertaken to detach peculiarities of shapes specific to two culturally different groups of population that left the burial ground. We succeeded in solving the task with the aid of geometrical morphometry in about a half of cases. In the third example an attempt is made to determine earthenware produced by different potters. For that purpose 30 vessels made by 6 professional potters of high skills and 15 vessels made by three potters who had no stable skills of earthenware production were used. In result of geometrical morphometry method application several conditional arrays of vessels have been detached. As it happens, vessels that have virtually nothing in common in their morphology, technology of production and skill level of potters who made the vessels allotted these arrays. Data considered allow making the conclusion that the biggest efficiency of geometrical morphometry application is achieved in search of peculiarities built in general proportionality of earthenware shapes. But an inefficiency of geometrical morphometry method is marked in solution of more complicated tasks related to analysis of detailed peculiarities of vessel outlines. The results obtained put in question possibilities to consider the geometrical morphometry as a sound method of archeological vessel shapes study.
