From Science to Fashion: Photography and the Production of a Surrogate Colony in Weimar Germany

This article examines German colonial cultures in the post-World War I period following Germany’s loss of a colonial empire. Photography had long been embedded in both the practical and ideological production of empire, but after 1918 took on an especially significant role in constructing a ‘surrogate colony’ that kept the colonial idea alive in the absence of direct colonial rule. The dynamics of this surrogate colony are especially evident in the publications of the organised colonial movement. Drawing on these publications, I argue that the colonial movement produced a surrogate colony that was as much about the management of gendered and racialised German populations as it was about propagandising for a return to colonial rule. Photography played a key role in bringing together two areas that underlay this gendered and racialised dynamic: science and commercial culture. I thus begin by tracing the way in which photographic scientific cultures, in particular in the fields of medicine, anthropology, and racial science, shaped the contours of the surrogate colony. These scientific cultures emerged in an unstable relationship with mass commercial photographic cultures, with the article then turning to an exploration of ‘colonial fashion photography’. The foregrounding of clothing and bodies in this photography highlights the complex relationship between scientific and commercial photography, which is shown to be deeply implicated in the production of racialised and gendered forms of embodiment.     

Development and application of software packages in welding engineering

The weldability of some material is analyzed with simple calculating program in this paper, and weldability testing data are shared through database system. The welding procedures are designed with help of expert systems, and the knowledge is shared among welding engineers. Not only the preparing progress of the welding documents is completed with database systems but also the complex decision on the necessity of the qualification test according to the present procedure qualification records (PQRs) and manufacture codes is made. Moreover, the artificial neural network (ANN) technique is proven to be one of the effective ways to predict mechanical properties of welded joints when there are enough tested data to train the models. Finally, the achievements in modeling microstructure of welded joints are introduced, especially in solid transformation and grain growth in both heat-affected zone (HAZ) and welded molten pool.     

The influence of anger,impulsivity, sensation seeking and driver attitudes on risky driving behaviour among post-graduate university students in Durban,South Africa

Introduction

Road traffic accidents (RTAs) constitute a serious global health risk, and evidence suggests that young drivers are significantly overrepresented among those injured or killed in RTAs. This study explores the role of anger, impulsivity, sensation seeking and driver attitudes as correlates for risky driving practices among drivers, drawing comparisons between age and gender.

Method

The study used a cross-sectional survey design, with a sample of 306 post-graduate university students from two universities in Durban, South Africa, who completed the self-administered questionnaire.

Results

The results indicate that drivers with higher driver anger, sensation seeking, urgency, and with a lack of premeditation and perseverance in daily activities were statistically more likely to report riskier driving acts. Males reported significantly more acts of risky driving behaviour (RDB) than females. Driver attitudes significantly predicted self-reported acts of RDB on most indicators. Older drivers (25 years and older) had safer driver attitudes and a lower sense of sensation seeking and urgency in life.

Conclusion

Interventions targeting young drivers, which focus on impeding the manifestation of anger, impulsivity and sensation seeking are recommended. Also, the empirical support for the attitude–behaviour hypothesis evidenced in this study vindicates the development or continuation of interventions that focus on this dynamic.
