Empirical evidence suggests that sibling structure
influences children’s educational outcomes:
While the negative effect of the number of siblings
is quite consistent, there are mixed findings
for birth order and birth spacing. According to the
resource dilution hypothesis, differences between
siblings occur because siblings have to share family
resources. Having a larger number of siblings,
being a later-born child as well as narrow age
gaps between siblings can affect the parental resources
available for each child, which may thus
negatively affect educational outcome. To study
the effects of sibling structure, we use longitudinal
data from the BiKS-8-14 study at the end of
elementary school, focusing on children’s vocabulary
Our results indicate an expected negative effect
for increasing number of siblings particularly
when children originate from families with a lower
educational background. Regarding birth order,
we also find differential effects by parents’ education,
as only children from less educated families
suffer from being a later-born child. No effects
can be identified for children’s birth gaps in
relation to younger siblings as soon as number of
siblings is being considered, whereas longer spacing
between a child and his/her older siblings is
positively related to vocabulary competences.
With respect to possible changes across time, sibling
effects appear to be rather stable at the end of
The relationship between the Bible and Children in Africa is a topic of highest relevance. This book is treating it in two main perspectives which often are intertwined:
| The exegetical perspective “Children in the Bible” is dealing with the concepts of childhood in biblical texts, asking for example: How are children conceived in different texts. What is their status in family, society and church? What is their relation to God? What is the metaphoric use of childhood in biblical soteriology? What is the function and meaning of calling adult persons “children” (of God, or of the Apostle)?
| The contextual perspective “African children of today and the Bible” is dealing with the different life settings African children find themselves in and how the Bible is present in these life settings. Here the questions for example are: What is the status of children in family and society? How are traditional concepts of childhood changing under the conditions of poverty, HIV/AIDS and violence? How are the ideas and ideals of childhood influenced by the Bible? What is the role of the Bible in child-education? Can children’s rights be established with help of the Bible?
This volume of BiAS 17 is collecting the papers presented at the 2012 BiAS meeting in Gaborone, Botswana, with some additional contributions.
Research on expatriates indicates that substantial differences exist within internationally
active employees. Several typologies of expatriates have been suggested to account for this
diverseness. However, empirical evidence on the accuracy of these classification schemes is
scarce. Based on these research efforts, we introduce a data-based taxonomy of internationally
mobile managers. By means of sequence analysis we derive four career patterns from the
curriculi vitae of 202 German managers. These patterns are built on the dimensions mobility
and duration of the stays abroad. We further show that these patterns differ with regard to
various individual and organizational variables. Based on these findings, we argue that
expatriation career management practices and responsibilities need to be differentiated.
It may be fun to perceive illusions, but the understanding of how they work is even
more stimulating and sustainable: They can tell us where the limits and capacity of
our perceptual apparatus are found—they can specify how the constraints of perception
are set. Furthermore, they let us analyze the cognitive sub-processes underlying our
perception. Illusions in a scientific context are not mainly created to reveal the failures of
our perception or the dysfunctions of our apparatus, but instead point to the specific power
of human perception. The main task of human perception is to amplify and strengthen
sensory inputs to be able to perceive, orientate and act very quickly, specifically and
efficiently. The present paper strengthens this line of argument, strongly put forth by
perceptual pioneer Richard L. Gregory (e.g., Gregory, 2009), by discussing specific visual
illusions and how they can help us to understand the magic of perception.
The present study challenges the notion that judgments of artistic quality are based on stable aesthetic standards. We propose that such standards are a delusion and that judgments of artistic quality are the combined result of exposure, elaboration and discourse. We ran two experiments using elaboration tasks based on the Repeated Evaluation Technique (RET) in which different versions of the Mona Lisa had to be elaborated deeply. During the initial task, either the version known from the Louvre or an alternative version owned by the Prado was elaborated; during the second task, both versions were elaborated in a comparative fashion. After both tasks, multiple blends of the two versions had to be evaluated concerning several aesthetic key variables. Judgments of artistic quality of the blends were significantly different depending on the initially elaborated version of the Mona Lisa indicating experience-based aesthetic processing, which contradicts the notion of stable aesthetic standards.
