Abstract: This dissertation is concerned mainly with the potential of solar energy in Malta, and its utilization for domestic water heating. It has been laid out in four chapters as follows:
The first chapter is entitled ‘Non Renewable and Renewable Energy Sources’. The non-renewable energy sources are described in detail in the first part – particular attention is given to the fossil fuels oil, coal and natural gas, their supply and consumption, their economic and environmental impacts and their supplies for the future. The information as presented, stresses the need and lays importance on the fact that developed regions of the world can and should conserve liquid fuels so that the developing world will have access to these fuels that are ideally suited for economic development. Another aspect is dealt with is that irrespective of what improvements in energy efficiency can be achieved it is clear that the present sources of energy will ultimately become too expensive to extract, become relatively scarce and therefore eventually would to be replaced by other alternative sources. This chapter includes also a section on energy in Malta with importance given to the electricity generation, particular to the domestic sector.
Discussion on the alternative sources of energy is presented in the second section of this chapter. This section introduces the reader to one important renewable energy source – solar energy. Developing countries like Malta, should lay importance on such an abundant source, firstly to supplement their energy needs and secondly to save on their import fuel bills. Solar energy is being widely advocated as a future energy source and this section discusses mainly the utilization of such a source by passive and active systems.
Before implementing such Passive and Active applications of solar energy as discussed in Chapter I, importance first and foremost has to be given to the location, the prevalent climatic conditions and insolation contribution, since such conditions if favourable could stimulate strongly the potential for the utilization of such solar applications. In fact Chapter II ‘Meteorology and Solar Radiation in Malta’ provides such information on local meteorological conditions such as air temperature, air humidity, winds, sunshine hours, and most importantly the Radiation Climate in the Maltese Islands. Such information as presented shall offer valid assistance for analysing those solar systems active or passive which could be installed for various domestic needs.
Chapter III ‘Solar Flat Plate Collectors and their use for Domestic Solar Water Heating’ is concerned with one particular and important application of solar energy for Malta. This chapter describes the solar water heaters, their basic parts, and technique involved for producing hot water by two important types of solar systems – the Thermosyphon and the Forced Circulation. This chapter includes also information on the Austrian-Maltese Research Centre and its functions.
A method of estimating the useful output of a particular domestic solar water heater, assembled locally and operated by the thermosyphon system is presented in Chapter IV, dealing with the ‘Economic analysis of a Domestic Solar Water Heater’. Obtaining the necessary data on the thermal performance of the system together with data on annual insolation, I could then proceed to the economic evaluation of the solar device by the present worth, annual cost and break-even point methods in comparison to the electric water heater.
Described in this chapter is the theoretical aspects and technique of the method used for cost analyses together with the derivation of the various formulae used. This analysis can be considered as a case study, an application of the principles discussed in the context of conditions predominant in Malta.

Abstract: The main objective of this study is to analyse the performance of the various sectors of economic activity in Gozo offering employment opportunities to the island’s labour force, with a view to forecast the level of employment in the short run. All the leading sectors will thus be examined in terms of employment capacity and their contribution to total employment.
A second objective is concerned with making estimates of the availability of manpower in order to compare manpower requirements with manpower availability. One possible kind of disequilibrium which may result is unemployment.
Forecasting future levels of employment and unemployment requires sets of information according to the method or technique adopted. Unfortunately, relevant information related to the Gozo labour market is very minimal. In fact, no useful official data whatsoever exist that treat Gozo as a separate region except for population estimates and manpower in the agricultural sector.
This study is, therefore, almost entirely based on unpublished data obtained from the Department of Labour and Emigration. However, the department has been collecting data regarding employment in Gozo since September 1978 and the last data available at the time of this research are those for June 1983. The information gathered consists mainly of a breakdown of the Gozo labour force according to the various sectors of industry. Thus, the sample size used throughout this study is a time series consisting of twenty quarterly observations. […]

Abstract: The Members of the House of Representatives are elected by the citizens to represent
them and one of their most important functions is that of ensuring that public funds
are used effectively and efficiently, according to the needs and aspirations of those
they represent. This was the reason behind the creation of the Standing Committee
on Public Accounts and the objective of this study is that of analysing its work in the
last two legislatures in order· to establish how effective and efficient this committee is
in reaching its goals.
The study is divided into three parts. The first part consists of an analysis of the
history and the way the present British Public Accounts Committee functions whilst
the second part tackles the same aspects for its Maltese equivalent. The study will
show that the Maltese Public Accounts Committee was closely modelled on the
British one. The third part of this study is an in-depth analysis of the minutes,
transcripts and related documents of two controversial cases which the Maltese
Public Accounts Committee had to scrutinize.
The study concludes that despite the fact that the Maltese Public Accounts
Committee is reaching its goals, this is not being done in the most efficient and
effective way and recommends changes that would make the Maltese Public
Accounts Committee more effective and efficient

Abstract: This dissertation is a study of
the Public Service Commission as it has
functioned in Malta since 1938. It has
been prepared within the last six months
and consequently it could not have taken
into consideration the proposals contained
in the Malta (Constitution) Order in
Council, 1959 for the new type of Public
Services Commission. The theme of this
paper is therefore the Public Service
Commissions on the eve of these new
developnents.
