Study Approach

ABSTRACTIn recent years South African cities have become home to a large number of undocumented migrant workers. If trade unions do not organise undocumented migrant workers, it opens up such workers to exploitation and maltreatment by employers, thereby creating a split labour market that undermines the entire labour movement. This article focuses on the responses of the national trade union movement in the private security sector to the presence of undocumented workers at the grassroots level. Using a case study approach, we find that the pressures of labour market informalisation in the industry prompt unions to seek to maintain and advance their position from their traditional support base of citizen workers rather than attempt to include new groups. The failure to engage is reinforced by anti-immigrant attitudes which link foreigners with problems in the industry such as low wages and portrays such workers as co-conspirators rather than comrades. While justice and solidarity have always been the foundation of trade unionism in South Africa, the movement is in danger of failing this test if the current situation in terms of the exclusion of undocumented foreign workers persists.

Over the last two decades, in a number of EU Member States labour migration in the construction industry has predominantly taken the form of the posting of workers. This article traces the responses of the German construction union IG BAU to this phenomenon. To this end, it distinguishes between three levels of action: relations with the state, relations with employers and autonomous action. It shows that the union's efforts have concentrated on the first two levels. IG BAU's steps to include migrant workers into its ranks have been taken only cautiously. While the union has achieved a number of successes in terms of regulating the labour market, limits of these policies have become apparent. There are signs that IG BAU has reacted to these limits by developing more inclusive organisational policies, notably by founding the European Migrant Workers Union.

The Relationship

This chapter examines the relationship between migrant workers and trade unions in different host countries. Based on a series of biographic interviews with Estonian migrant workers in Finland and Albanian workers in Italy and Greece, it makes the case that when migrants join unions, it is usually a result of an individual movement out of precarious and sometimes informal work into secure, formal work relations. The availability of such secure jobs for migrants is a result of inclusive national institutions of labour market regulation, and a strong trade union workplace presence. Although in all three countries the migrants were quite passive and instrumentalist in their relations to unions, they nonetheless generally joined when working in unionized contexts, as a way of conforming to workplace norms.

AbstractThis paper deals with a possibility to use the ground-based method of observation in order to solve basic problems connected with the solar corona research. Namely:1.heating of the solar corona2.course of the global cycle in the corona3.rotation of the solar corona and development of active regions.There is stressed a possibility of high-time resolution of the coronal line photometer at Lomnický Peak coronal station, and use of the latter to obtain crucial observations.

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.

The discussion was separated into 3 different topics according to the separation made by the reviewer between the different periods of waves observed in the sun :1) global modes (long period oscillations) with predominantly radial harmonic motion.2) modes with large coherent - wave systems but not necessarily global excitation (300 s oscillation).3) locally excited - short period waves.

Today, in image analysis the broadest possible rationalization and economization have become desirable. Basically, there are two approaches for image analysis: The image analysis through the so-called scanning methods which are usually performed without the human eye and the systems of optical semiautomatic analysis completely relying on the human eye.The new MOP AM 01 opto-manual system (fig.) represents one of the very promising approaches in this field. The instrument consists of an electronic counting and storing unit, which incorporates a microprocessor and a keyboard for choice of measuring parameters, well designed for easy use.Using the MOP AM 01 there are three possibilities of image analysis:the manual point counting,the opto-manual point counting andthe measurement of absolute areas and/or length (size distribution analysis included).To determine a point density for the calculation of the corresponding volume density the intercepts lying within the structure are scanned with the light pen.

Equilibrium Vapor Pressure

In order to observe room temperature hydrated specimens in an electron microscope, the following conditions should be satisfied: The specimen should be surrounded by water vapor as close as possible to the equilibrium vapor pressure corresponding to the temperature of the specimen.The specimen grid should be inserted, focused and photo graphed in the shortest possible time in order to minimize dehydration.The full area of the specimen grid should be visible in order to minimize the number of changes of specimen required.There should be no pressure gradient across the grid so that specimens can be straddled across holes.Leakage of water vapor to the column should be minimized.

Pineal Ultrastructure

There have been many reports which establish a relationship between the pineal and sexual structures, including gonadal hypertrophy after pinealectomy, and gonadal atrophy after injection of pineal homogenates or of melatonin. In order to further delineate this relationship the pineals from 5 groups of female rats were studied by electron microscopy:ControlsPregnant ratsAfter 4 weekly injections of 0.1 mg. estradiol benzoate.After 8 daily injections of 150 mcgm. melatonin (pineal hormone).After 8 daily injections of 3 mg. serotonin (melatonin precursor).No ultrastructural differences were evident between the control, and the pregnancy and melatonin groups. However, the estradiol injected animals exhibited a marked increase in the amount and size of rough endoplasmic reticulum within the pineal cells.
