Body Height Measurements in Images

Abstract:  For any measurement of a person's height in an image, a difference exists between the actual height of the person and the image measurement. In order to gain knowledge about statistical behavior of differences between actual and measured heights it is necessary to make reference recordings, e.g., of test persons under the same recording conditions. To test whether the differences are dependent on camera and further circumstances, an experiment was set up which involved the measurement of 22 test persons using three cameras of varying quality. Reproducibility of measurements per image appears to be strongly dependent on the camera (quality), whereas systematic bias differs with the view point of the camera. Operator dependency of the measurement process is found, so its repetition by different operators is recommended.     

Does Belgium (still) exist? Differences in political culture between Flemings and Walloons

The emergence of two separate political systems in Belgium is the logical consequence of a gradual cultural and social divergence between Flanders and Wallonia. It is particularly in Flanders that Belgian nationhood is being put under pressure by a subnational identity. At the same time, there are still widespread emotional ties to Belgium, albeit stronger in Wallonia than in Flanders, that act as an important counterbalance to both the social and institutional centrifugal forces. Church involvement was traditionally higher in Flanders, but the stronger decline in the latter region has levelled off this difference. In both regions, the impact of pillarisation on voting behaviour is diminishing. As concerns the attitude towards foreigners, Flemings are more concerned about maintaining their own culture, while the Walloons are more concerned about the alleged economic and social threat. Other differences with regard to values exist, but are relatively small from a comparative perspective.     

Why do Adolescents Gather Information or Stick to Parental Norms? Examining Autonomous and Controlled Motives Behind Adolescents’ Identity Style

Self-determination theory (SDT) distinguishes between autonomous and controlled reasons for people’s behavior and essentially states that beneficial effects for individuals’ psychosocial adjustment will accrue when behavior is guided by autonomous (rather than controlled) motives. The present study tested this assumption in the area of adolescents’ identity styles. In a sample of mid-adolescents (N = 247; 53% female), it was found that the motives for using an information-oriented or a normative identity style explained additional variance beyond the identity styles as such in two of the adjustment outcomes examined. Specifically, autonomous motives underlying these two identity styles were positively related to commitment and personal well-being, whereas controlled motives were negatively related to these same adjustment outcomes. Perceived autonomy-supportive parenting was examined as a possible antecedent of the motives behind identity styles. Consistent with hypotheses, it was found that autonomy-supportive parenting was positively related to autonomous motives and negatively to controlled motives underlying identity styles. Implications for future research on the motivational dynamics behind identity development are discussed.     

The Sudanese Woman

The nature of the relationship between (proto-)feminism and (anti-)imperialism is highly contested. A case in point is the work of Olive Schreiner, and the articulation of gender politics with (anti-)imperialism which has been subjected to repeated scrutiny in the last twenty years. One strand of criticism, exemplified by critics like Laura Chrisman, Anne McClintock and Carolyn Burdett, argues that Schreiner generally successfully integrates a (proto-)feminist politics with criticism of imperialism in her writing produced after The Story of an African Farm . However, her first novel is viewed as more problematic in this regard. While acknowledging it as a major early text of the women's movement, such critics see the novel as in large measure endorsing prevailing Victorian ideologies of racial hierarchy. Drawing on the methodology of Sub-altern Studies, Moore-Gilbert proposes a rather different interpretation of The Story of an African Farm . Following the lead of Ranajit Guha and his colleagues, he seeks to trace the impact of (the resistance of) the colonized subaltern on the colonizer's unconscious and how this is reflected in the colonizer's regimes of representation and self-image. He proposes that Waldo can be read 'catachrestically' as a figure of the (partially resistant) colonized who at the manifest level occupy only a marginal role in Schreiner's text. The aim is not to overturn readings of Waldo that see him as an exemplary 'modern', embodying many of the characteristics of western civilization at the time. Rather, the argument is that such a 'catchrestic' reading can co-exist simultaneously with these received interpretations of his role, thus corroborating the perception of the Subaltern Studies historians on the existence of conflicts and contradictions in the colonizer's unconscious that mark the (oppositional) presence of the (historically effaced) subaltern. Against their emphasis, however, Moore-Gilbert suggests that the colonizer's unconscious can also be the seat of 'progressive' drives. And the presence of such drives on Schreiner's novel suggests that its racial politics are more consonant with those of her later work than is commonly assumed.     

Economic Benefits of Rural Feeder Roads: Evidence from Ethiopia

We estimate households’ willingness-to-pay for rural feeder roads in Ethiopia. Using purposefully collected data, we compare the economic behaviour of households by remoteness to estimate the benefits of access to feeder roads. Although we cannot definitively assert a causal relationship, we cautiously estimate that gravel roads have internal rates of return of 12–35 per cent. These results suggest that rural feeder roads may have relatively high rates of return even in unfavourable settings where (a) small-scale farmers have low levels of marketed agricultural surplus, (b) non-farm earning opportunities are negligible, and (c) motorised transport services are not guaranteed.     

Network of Networks: Preliminary Lessons from the Antwerp Port Authority on Crisis Management and Network Governance to Deal with the COVID-19 Pandemic

In this article, the authors describe and illustrate what they call a “network of networks” perspective and map the development of a lead network for the Antwerp Port Authority that governed organizations and networks in the port community before and during the COVID-19 pandemic. They find that setting a collective focus and selective integration are crucial in the creation and reproduction of an effective system to adequately deal with a wicked problem like the COVID-19 pandemic. The findings on crisis management and network governance are used to engage practitioners and public policy planners to revisit the current design and governance of organizational networks within organizational fields that have been hit by the COVID-19 pandemic.     

Technology in policing: Experiences,obstacles and police needs

Increasing efforts are made by police forces all over the world to optimize the use of technology in policing and remove any obstacles as new and existing technologies provide new opportunities for law enforcement, criminal investigation and prosecution. This contribution describes results of research on which technologies are currently used at police forces and other criminal investigation organizations in the Netherlands, their experiences with these technologies and their needs and preferences in this regard. For existing opportunities the prevalence and satisfaction of several technologies in policing, including wiretapping, fingerprints, DNA research, database coupling, data mining and profiling, camera surveillance and network analyses were investigated. For new opportunities the most promising technologies (i.e., promising according to the police forces) were mapped. Furthermore, an inventory was made of the legal, technological and organizational obstacles police forces encounter when using different technologies for purposes like law enforcement, criminal investigation and prosecution.
