Although the cost-effective integration of diverse smart object technologies like radio-frequency identification (RFID), real-time locating systems (RTLS), and wireless sensor networks (WSN) into existing enterprise infrastructures is very important for companies, integration aspects are ignored by researches frequently. Furthermore it could be observed, that existing commercial middleware products aiming at integration ignore the trend of consolidation between diverse smart object technologies by focusing on passive RFID only. This paper introduces the concept of an integration platform for diverse smart object technologies together with an abstract software architecture. The functionalities that such a platform should provide are derived from the requirements of real world applications and aim at drastically reduced integration costs.
This paper examines the effects of a professional development programme on the attitudes towards the teaching and learning of teachers in the Anglophone part of Cameroon. The development programme combines a multiplier system with school-based in-service training. The research compares the effects that the training had on the attitudes of three groups of teachers in a control group design: (1) teach- ers participating in the in-service training, subdivided into (1a) teachers trained as multipliers and (1b) teachers trained by the multipliers, and
(2) teachers who did not participate in the training. The study featured a quantitative control group design (n = 292) and is intended to contribute to the discussion on the sustainable effects of in-service teacher training in low-income countries. The data collection was conducted in 13 secondary schools in Cameroon. The results suggest that the programme had effects on the teachers’ attitudes and classroom practices.
Abstract – Study 01
Research about parent effects on family behavior focuses on intergenerational transmission: whether children show the same family behavior as their parents. This potentially overemphasizes similarity and obscures heterogeneity in parent effects on family behavior. In this study we make two contributions. First, instead of focusing on isolated focal events, we conceptualize parents’ and their children’s family formation holistically as the process of union formation and childbearing between age 15 and age 40. We then discuss mechanisms likely to shape these intergenerational patterns. Second, beyond estimating average transmission effects, we innovatively apply multichannel sequence analysis to dyadic sequence data on middle class American families from the Longitudinal Study of Generations (LSOG, N=461 parent-child dyads). The results show three salient intergenerational family formation patterns among this population: a strong transmission, a moderated transmission, and an intergenerational contrast pattern. We examine what determines parents’ and children’s likelihood to sort into a specific intergenerational pattern. For middle class American families, educational upward mobility is a strong predictor of moderated intergenerational transmission, whereas parent-child conflict increases the likelihood of intergenerational contrast in family formation. We conclude that intergenerational patterns of family formation are generated at the intersection of macro structural change and family internal psychological dynamics

Sibling studies have been widely used to analyze the impact of family background on socioeconomic and, to a lesser extent, demographic outcomes. We contribute to this literature with a novel research design that combines sibling comparisons and sequence analysis to analyze longitudinal family formation trajectories of siblings and unrelated persons. This allows us to scrutinize in a more rigorous way, whether there is sibling similarity in family formation trajectories and if siblings’ shared background characteristics, such as parental education and early childhood family structure can account for similarity in family formation. We use Finnish register data from 1987 until 2007 to construct longitudinal family formation trajectories in young adulthood for siblings and unrelated dyads (N=14,257 dyads). Findings show that siblings’ family formation is moderately but significantly more similar than for unrelated dyads, also after controlling for crucial parental background characteristics. Shared parental background characteristics add surprisingly little to account for sibling similarity in family formation. Instead, gender and the respondents’ own education are more decisive forces in the stratification of family formation. Yet family internal dynamics seem to reinforce this stratification, such that siblings have a higher probability to experience similar family formation patterns. Particularly patterns that go along with economic disadvantage are concentrated within families. This is in line with a growing body of research highlighting the importance of family structure in the reproduction of social inequality.
Abstract – Study 03
This study investigated the association between childhood living arrangements and early family formation in Germany. Drawing on persisting socio-environmental differences between East and West Germany the author addressed the question whether the association of childhood family structure and the early transition to adulthood varies in different societal contexts. In line with research from other countries, the analysis based on data from the German Family Panel (pairfam/DemoDiff; N = 3643) showed that children from non-traditional family structures experience important demographic transitions faster than children who have been raised by both biological parents. In addition to this rather ubiquitous association, the study revealed considerable context-specific differences, which point to the long-term consequences of the post-war separation of East and West Germany. First, although increasing in relevance, family structure was less predictive for early family formation in East Germany. Second, the results indicated that the link between childhood family structure and the reproduction of social inequality, which has been found in many studies from the US, could only be replicated for West Germany. In East Germany, educational attainment did not mediate the effect of childhood living arrangements on early family formation, nor was it associated with an increased probability of ever having lived in an alternative family structure.
This study demonstrates the existence in Seville of lusterware production centers that operated under the authority of the Abbadid princes over several decades
during the second half of the eleventh century. Deliberately
situated within the Taifa period, this material clearly bears the direct influences of the various luxury ceramics produced in both the Western and Eastern regions of the Islamic realm, a phenomenon not unheard
of in the history of islamic ceramics. The fragments included in this grouping possess decorativ and technical features that have allowed for a distinct characterization
of this type of lustetware. Research conducted thus far
has found these types represented mainly in the southern
regions of the Iberian Peninsula.
