As part of a research project on antisocial behaviour of Cypriotyouth we postulated the hypothesis that the individual’s overall psychological adjustment(comprised and represented by the Total Composite Test Score and the scores on the seven scalesof the Personality Assessment Questionnaire – PAQ), can predict antisocial behaviour in formof racistic tendencies in a given population. We tested 1,185 Greek Cypriots (aged 15-23 years)using PART’s Personality Assessment Questionnaire (PAQ) and other especially developedquestionnaires. Here we present the findings of the initial stages of our research, namely theanalysis of the responses of the Greek Cypriot sample on the Adult-PAQ scales. The majority ofthe Greek Cypriot respondents were found to be in the zone of good emotional and behaviouralfunctioning. These findings, paired with the results of the Cyprus Child PARQ for high perceivedacceptance and low rejection in childhood (Demetriou and Christodoulides, 2006) seem toconfirm Rohner’s postulates in the Parental Acceptance Rejection personality sub theory. http://ktisis.cut.ac.cy/handle/10488/4814 Title: An experimental investigation of the performance boundaries of a solar water heating system<br/><br/>Authors: Michaelides, Ioannis M.; Eleftheriou, Polyvios C.<br/><br/>Abstract: This paper presents the performance characteristics of a solar water heating system consisting of a 3 m2 flat plate collector and a 68 L tank, from readings taken over a period of 2 years under real weather conditions. It focuses on the characteristics and the behavior of the system, its response to solar radiation and hot water flow rate through the collector under no load conditions and in the evaluation of the errors associated with the system performance measurements. The system behavior proved to be linear with small relative standard deviations (less than 15%) within the values of the calculated errors and also relatively insensitive to solar radiation fluctuations ranging from 800 to 1100 W/m2. Flow rate variations from 0.07 and up to 0.25 L/s did not produce any noticeable effects on the energy collected in the storage tank of the system under investigation. The calculated absolute errors in the system instantaneous efficiency ranged from 34% for low flow and up to 20% for the high flows. http://ktisis.cut.ac.cy/handle/10488/4799 Title: Wastewater reuse in coastal areas – Nutrient flow evaluation<br/><br/>Authors: Kathijotes, Nicholas<br/><br/>Abstract: Weather changes and population increase on coastal zones clearly dictate higher demand for water which; in arid and semi arid regions is considered as a limited resource, with almost all groundwater resources under heavy pressure. Future demands will not be met by traditional water resources like surface and ground water. In order to handle increased water demand, the treated wastewater originating from municipal wastewater treatment plants has to be developed and offered to farmers for agricultural irrigation. Most of marine pollution arises from land-based activities such as urban development and sewage disposal, manufacturing, transport, energy production, and especially from tourism supporting agricultural activities. These inputs are a potential risk to ground water and the marine environment that need to be investigated. Nutrient effects on soils are then amplified, by investigating areas irrigated by wastewater and nearby sites irrigated with groundwater. Profile samples were taken in a field irrigated with treated wastewater, and in a nearby field irrigated with fresh farm water from the site for over ten years. All other variables like, crop types, irrigation modes and quantities, weather conditions were the same. Results suggest that, even though there is an increased nutrient input, no serious effects result through wastewater reuse and problems detected are manageable and may be handled with proper techniques. The aims of this investigation is to determine the distribution patterns of nutrients into the soil profile resulting from wastewater reuse .These nutrients eventually may end up into the groundwater creating quality degradation (eutrophication) of this resource as well as to the immediate marine environment. Results show an increase of nutrient values resulting from wastewater reuse at almost all experimental levels, but these increases are considered as manageable if proper care is exercised. http://ktisis.cut.ac.cy/handle/10488/4798 Title: Protection of Marine Environment in Developing Countries- Management of Nutrient Inputs<br/><br/>Authors: Kathijotes, Nicholas<br/><br/>Abstract: The management and treatment of sludge in developing countries, from on-site sanitation systems has neither been addressed by problem holders nor by researchers. All septic tanks need to be desludged regularly in order to maintain a certain level of treatment efficiency and minimize ecological and eventual marine pollution incidences. Practices followed in developing countries are discussed and lessons learned are emphasized for promoting sustainable community development. Stakeholder identification and participation and their cooperation through the process, as well as new regulations on service provision and management procedures are addressed in this study.
