Kommunikation in E-Learning-Veranstaltungen. Erfahrungen der Studierenden und ihre Präferenzen für Online- oder Face-to-Face-Kommunikation

Altogether, 2,196 students from 29 Austrian universities took part in an empirical investigation on learning and communication in e-learning courses. The students completed a questionnaire on their experiences in an actual e-learning course, on their perceived learning achievements, and their enjoyment of the course. Furthermore, they expressed their preferences for online or face-to-face communication. All in all, students were satisfied with their course. They did not prefer one communication setting over another. They preferred online-communication for the distribution of information but advocated face-to-face communication when joint learning and cooperation are important or when socio-emotional relations are to be developed. The results of the study advocate blended-learning designs and give recommendations for which communication purposes online and for which face-to-face settings are more adequate.     

On the independence of history: experience spill-overs between experiments

A central understanding in experimental economics is that subjects’ decisions in the lab are independent of history. We test whether this assumption of between-experiment independence is indeed justified. We analyze experiments with an allocation decision (like a dictator or ultimatum game) and find that participation in previous experiments tends to increase the amount subjects allocate to themselves. Hence, independence between experiments cannot be presumed if subjects participate repeatedly. The finding has implications for the interpretation of previous allocation decision results and deserves attention when running future experiments.

Formulating waste management strategies based on waste management practices of households in Santiago de Cuba, Cuba

Rapid urbanisation, population growth and changes in lifestyles in low- and middle-income countries contribute to increasing the per capita domestic waste generation. This trend leads to deplorable environmental and public health conditions, especially in rapidly expanding cities of low- and middle-income countries lacking appropriate waste management systems, Santiago de Cuba is no exception. To improve solid waste management in the city of Santiago de Cuba, the generation of household waste was studied and individual waste treatment approaches were assessed. The principle of a household level analysis was adopted to enable the development of strategies based on the specific conditions of households, their awareness and needs.In February 2004, a survey covering 1180 households was conducted on issues such as monthly consumed goods, waste generated and its treatment. The waste generated by the households was subsequently assessed by means of a measuring campaign. The measured volume not only comprised the collected waste fraction but also the waste materials treated on-site or recovered and recycled by all the different means available.The paper contains the results of the composition and distribution of the waste generated by the households as a function of socio-demographic data. Furthermore, the paper describes the various household treatment strategies dependent on specific waste material types. Several types of household waste can be differentiated by statistical cluster analysis. These household types are characterised not only by the amount of waste generated but also by socio-economic status and waste treatment practices. The results obtained are used to develop a range of waste management strategies, each relating to a household type and characterised by its generated amount, waste material type and spatial urban distribution. Since the strategies are adapted to the requirements and needs of the households, they are more readily accepted by the population concerned. Such socially anchored strategies will contribute to improving the waste situation in the city of Santiago de Cuba and allow an optimised allocation of local resources.
