A cross-national comparison of cultural value orientations of Indian, Polish, Russian and American employees

This study examines the cultural value orientations (VOs) of employees (managerial and non-managerial) working in three categories of organizations (professional, technical and local services) in India, Poland, Russia and the USA. The analysis is conducted at both the national and organizational levels. The paper hypothesizes cultural differences at the country level and cultural similarities among employees working for professional and technical oriented organizations and divergence in the VOs of employees working for local services organizations. It also hypothesizes differences in the VOs of managerial and non-managerial employees in the four countries. The investigation has been conducted with the help of a questionnaire survey of 1,852 respondents. The outcomes of the analysis show that there are both cross-country cultural differences and similarities among the VOs of employees of the four nations. Further, significant cultural convergence emerges in the VOs of employees working for both professional and technical organizations, however, no significant cultural similarities or differences are observed for employees of service-based organizations in the four countries. There are some similarities emerging between managerial employees in the research countries. The research contributes to the fields of cross-cultural management, international management and international human resource management.

Feasibility of a solar panel-powered liquid desiccant cooling system for greenhouses

To investigate the technical feasibility of a novel cooling system for commercial greenhouses, knowledge of the state of the art in greenhouse cooling is required. An extensive literature review was carried out that highlighted the physical processes of greenhouse cooling and showed the limitations of the conventional technology. The proposed cooling system utilises liquid desiccant technology; hence knowledge of liquid desiccant cooling is also a prerequisite before designing such a system. Extensive literature reviews on solar liquid desiccant regenerators and desiccators, which are essential parts of liquid desiccant cooling systems, were carried out to identify their advantages and disadvantages. In response to the findings, a regenerator and a desiccator were designed and constructed in lab. An important factor of liquid desiccant cooling is the choice of liquid desiccant itself. The hygroscopicity of the liquid desiccant affects the performance of the system. Bitterns, which are magnesium-rich brines derived from seawater, are proposed as an alternative liquid desiccant for cooling greenhouses. A thorough experimental and theoretical study was carried out in order to determine the properties of concentrated bitterns. It was concluded that their properties resemble pure magnesium chloride solutions. Therefore, magnesium chloride solution was used in laboratory experiments to assess the performance of the regenerator and the desiccator. To predict the whole system performance, the physical processes of heat and mass transfer were modelled using gPROMS® advanced process modelling software. The model was validated against the experimental results. Consequently it was used to model a commercials-scale greenhouse in several hot coastal areas in the tropics and sub-tropics. These case studies show that the system, when compared to evaporative cooling, achieves 3oC-5.6oC temperature drop inside the greenhouse in hot and humid places (RH>70%) and 2oC-4oC temperature drop in hot and dry places (50%

Remembrance of things past:the lingering impact of history on contemporary Polish-Ukrainian relations

This article investigates the continuing influence of the past on contemporary politics in Poland and Ukraine by examining the impact of the vocal 'informed' segment of public opinion on mutual relations between the two countries. The section 'What history?' examines the question of exactly what understanding of history matters so much in Polish-Ukrainian relations. The following sections examine how history influences the present, what are the contours of public opinion on Polish-Ukrainian relations within each state, and what is the impact of shared history on the contemporary politics of Polish-Ukrainian relations. Finally, the article suggests a potentially generaliseable hypothesis for future research.

Migration and mobility of new Polish migrants in England:narratives of lived experience

This thesis sets out to understand the act of migrating in a period of growing movement of people. It captures the subjective experience of individual migrants, as narrated in the migration stories of 32 “new” Polish migrants in the West Midlands region of England. Since the enlargement of the European Union in 2004, over half a million Poles have arrived and registered to work in the UK, constituting one of the largest migration movements in contemporary Britain and Europe. This influx of predominantly young migrants opened up public and academic debates regarding the social relations between the Polish migrants and the host society, their duration of stay, and the impact on the economy and social services. While a substantial amount of research has now been undertaken on this migration, this thesis highlights some of the significant features of migration to Britain and Europe today, namely its dynamic, fluid, complex and varied character. Through four themes of lived experience of migration, migration and mobility, gender, and return migration, this thesis uncovers and explores the phenomenon of post-2004 EU migration from the perspective of migrants themselves. Migrant stories in this thesis are linked with experiences and meanings of migration, but also migrants’ emotions, perceptions, views and opinions. By exploring individual journeys of migration and deliberating over the determinants and consequences of migration, this thesis asks how the processes of migration and mobility come into play in the everyday lives of migrant people, and how this impacts on questions of identity, home, belonging, gender, as well as return.

A solar powered liquid-desiccant cooling system for greenhouses

Liquid desiccant systems are of potential interest as a means of cooling greenhouses to temperatures below those achieved by conventional means. However, only very little work has been done on this technology with previous workers focussing on the cooling of human dwellings using expensive desiccants such as lithium salts. In this study we are designing a system for greenhouse cooling based on magnesium chloride desiccant which is an abundant and non-toxic substance. Magnesium chloride is found in seawater, for example, and is a by-product from solar salt works. We have carried out a detailed experimental study of the relevant properties of magnesium rich solutions. In addition we have constructed a test rig that includes the main components of the cooling system, namely a dehumidifier and solar regenerator. The dehumidifier is a cross-flow device that consists of a structured packing made of corrugated cellulose paper sheets with different flute angles and embedded cooling tubes. The regenerator is of the open type with insulated backing and fabric covering to spread the flow of desiccant solution. Alongside these experiments we are developing a mathematical model in gPROMS® that combines and simulates the heat and mass transfer processes in these components. The model can be applied to various geographical locations. Here we report predictions for Havana (Cuba) and Manila (Philippines), where we find that average wet-bulb temperatures can be lowered by 2.2 and 3°C, respectively, during the month of May.

Energy saving and solar electricity in fan-ventilated greenhouses

Greenhouse cultivation is an energy intensive process therefore it is worthwhile to introduce energy saving measures and alternative energy sources. Here we show that there is scope for energy saving in fan ventilated greenhouses. Measurements of electricity usage as a function of fan speed have been performed for two models of 1.25 m diameter greenhouse fans and compared to theoretical values. Reducing the speed can cut the energy usage per volume of air moved by more than 70%. To minimize the capital cost of low-speed operation, a cooled greenhouse has been built in which the fan speed responds to sunlight such that full speed is reached only around noon. The energy saving is about 40% compared to constant speed operation. Direct operation of fans from solar-photovoltaic modules is also viable as shown from experiments with a fan driven by a brushless DC motor. On comparing the Net Present Value costs of the different systems over a 10 year amortization period (with and without a carbon tax to represent environmental costs) we find that sunlight-controlled system saves money under all assumptions about taxation and discount rates. The solar-powered system, however, is only profitable for very low discount rates, due to the high initial capital costs. Nonetheless this system could be of interest for its reliability in developing countries where mains electricity is intermittent. We recommend that greenhouse fan manufacturers improve the availability of energy-saving designs such as those described here.

Polish EU accession in comparative perspective:macroeconomics, finance and the government

This book is a collection of papers that focusses on the macroeconomic and financial aspects of EU accession of its largest new member, Poland, seen in comparative perspective. Two main themes are covered. One relates to empirical estimations, evaluating the effects of integration on fiscal balance, prices, seigniorage wealth and FDI flows. The second theme relates to institutional reform and policy recommendations. Discussion focuses on how transparency and fiscal rules, including those implied by EU accession, may help to reduce the deficit bias in fiscal policy; what is the institutional framework for low inflation and how to make the insurance sector regulation more efficient, including its implications for insurance offer for small and medium-size enterprises. Last but not least, the Irish model of development and the role of the foreign direct investment in it is discussed, including the applicability of the Irish policy in Poland and other new EU member states.

Privatisation, corporate control and employment growth:evidence from a panel of large Polish firms, 1996-2002

Using data on Polish firms this paper examines the relationship between corporate control structures, sales growth and the determinants of employment change. Privatised and de novo firms are the main drivers of employment growth; in the case of de novo firms, it is foreign ownership which underpins the result. Being privatised has a positive impact on employment but this is concentrated within a range of 3–6 years after privatisation. There are no systematic differences in employment response to negative sales growth across the ownership categories. Employment in state firms is less responsive to positive sales growth. From these results we infer that the behaviour of state firms is affected by both insider rent sharing and binding budget constraints.

Privatisation, corporate control and employment growth:evidence from a panel of large Polish firms, 1996-2002

Using panel data on large Polish firms this paper examines the relationship between corporate control structures, sales growth and the determinants of employment change during the period 1996-2002. We find that privatised and de novo firms are the main drivers of employment growth and that, in the case of de novo firms, it is foreign ownership which underpins the result. Interestingly, we find that being privatised has a positive impact on employment growth but that this impact is concentrated within a range of three to six years after privatisation. In contrast with the findings of earlier literature, we find evidence that there are no systematic differences in employment response to negative sales growth across the ownership categories. On the other hand, employment in state firms is less responsive to positive sales growth. From these combined results we infer that the behaviour of state firms is constrained by both insider rent sharing and binding budget constraints. Consistent with this, we find that privatised companies, three to six years post-privatisation, are the firms for whom employment is most responsive to positive sales growth and as such, offer the best hope for rapid labour market expansion.
