This paper provides an explanation for the observed persistence in income inequality across households in terms limited parental altruism. We postulate that the degree of parental altruism is ‘limited’ by the financial status of the parent. A poor parent not only has less ability, but also has less concern about children’s welfare. This generates a non-linearity in the human capital formation f...

Today business environment is highly dependent on complex technologies, and information is considered an important asset. Organizations are therefore required to protect their information infrastructure and follow an inclusive risk management approach. One way to achieve this is by aligning the information security investment decisions with respect to organizational strategy. A large number of ...

Measuring security controls across multiple layers of defense requires realistic data sets and repeatable experiments. However, data sets that are collected from real users often cannot be freely exchanged due to privacy and regulatory concerns. Synthetic datasets, which can be shared, have in the past had critical flaws or at best been one time collections of data focusing on a single layer or...

We re-assess the question of a systematic time delay between the formation of the progenitor and its explosion in a type Ia supernova (SN Ia) using the Hubble Higher-z Supernova Search sample (Strolger et al. 2004). While the previous analysis indicated a significant time delay, with a most likely value of 3.4 Gyr, effectively ruling out all previously proposed progenitor models, our analysis s...

[Context and motivation] To remedy the lack of security expertise, industrial security risk assessment methods come with catalogues of threats and security controls. [Question/problem] We investigate in both qualitative and quantitative terms whether the use of catalogues of threats and security controls has an effect on the actual and perceived effectiveness of a security risk assessment metho...

In this article we argue that current theories on socioemotional development during infancy need 5 to be reconceptualized in order to account for cross-cultural variation in caregiver–infant interaction. In line with the cultural-historical internalization theory of emotional development (Holodynski & Friedlmeier, 2006) and the ecocultural model of development (Keller & Kärtner, in press), we a...

Does private tutoring increase parental choice and improve student achievement, or does it exacerbate social inequalities and impose heavy costs on households, possibly without improving student outcomes? Private tutoring is now a major component of the education sector in many developing countries, yet education policy too seldom acknowledges or makes use of it. This survey of the literature e...

E-learning is emerging as a way of using technology to re-create a one-on-one learning environment for numerous participants at a time and has become prevalent in the higher education arena. In addition to traditional forms of cheating, many universities currently deal with issues of students in traditional classrooms who engage in technology-facilitated cheating. This paper recognizes the soci...

Knowledge Management (KM) has been recognized as a critical management strategy in generating competitive advantage for the organization. In order to protect organizational knowledge stored in or transferred through company’s Knowledge Management Systems (KMS), information security controls have to be incorporated into these systems. However, overly strict controls may adversely impact the perc...

Parental education is one of the main determinants of educational attainment. In research it is often measured using the education level of one parent, usually the father’s. This research investigates how well father’s education explains the variation in educational attainment for males and females, and compares this to models using mother’s education and those using both parents’ education. Th...
