Uncertain Belongings. Absent mourning, burial, and post-mortem repatriations at the external border of the EU in Spain

Since the mid-1980s, migrants from North African and sub-Saharan countries have irregularly crossed the Strait of Gibraltar, in the hope of a better future for themselves and their families. Travelling in small, poorly equipped boats without experienced captains has cost the lives of myriad border crossers. Many of these bodies will never be recovered and the bereaved will never know whether their relatives and friends are alive or not. The bereaved are thus condemned to a state of not knowing and uncertainty. Exploring the junction of death and belonging, I firstly open a discussion about the enigmatic relation between a dead body and a dead person and argue for the importance of the physical presence of the body for mourning. Secondly, I show how the anonymity of dead border crossers and their uncertain belongings are generated, concealed, or rewritten. Following the story of an undertaker, I thirdly examine post-mortem border crossings. Depicting the power relations within identification processes, I outline the ambiguity of the term belonging by emphasising the constitutive significance of personal belongings such as clothes to restore a person’s identity. Reflecting on the ethical relationships which different actors (including the researcher) undertake with the deceased, I aim at gaining a better understanding of the multiple belonging of dead border crossers found on Spanish shores.

From Personal Network to Institution Building: The Lifanyuan and the Formalization of Manchu-Mongol Relations

The Qing emperors, who ruled over China from 1644-1911, managed to bring large parts of Inner Asia under their control and extended the territory of China to an unprecedented degree. This paper maintains that the political technique of patronage with its formalized language, its emphasis on gift exchange and expressions of courtesy is a useful concept for explaining the integration of Inner Asian confederations into the empire. By re-interpreting the obligations of gift exchange, the Qing transformed the network of personal relationships, which had to be reinforced and consolidated permanently into a system with clearly defined rules. In this process of formalization, the Lifanyuan, the Court for the Administration of the Outer Regions, played a key role. While in the early years of the dynasty, it was responsible for collecting and disseminating information concerning the various patronage relationships with Inner Asian leaders, over the course of the 17th and 18th centuries its efforts were directed at standardizing and streamlining the contacts between ethnic minorities and the state. Through the Lifanyuan, the rules and principles of patronage were maintained in a modified form even in the later part of the dynasty, when the Qing exercised control in the outer regions more directly. The paper provides an explanation for the longevity and cohesiveness of the multi-ethnic Qing empire. Based on recently published Manchu and Mongolian language archival material and the Maussian concept of gift exchange the study sheds new light on the changing self-conception of the Qing emperors.

Comparison of 3D kinetic and hydrodynamic models to ROSINA-COPS measurements of the neutral coma of 67P/Churyumov-Gerasimenko

67P/Churyumov-Gerasimenko (67P) is a Jupiter-family comet and the object of investigation of the European Space Agency mission Rosetta. This report presents the first full 3D simulation results of 67P’s neutral gas coma. In this study we include results from a direct simulation Monte Carlo method, a hydrodynamic code, and a purely geometric calculation which computes the total illuminated surface area on the nucleus. All models include the triangulated 3D shape model of 67P as well as realistic illumination and shadowing conditions. The basic concept is the assumption that these illumination conditions on the nucleus are the main driver for the gas activity of the comet. As a consequence, the total production rate of 67P varies as a function of solar insolation. The best agreement between the model and the data is achieved when gas fluxes on the night side are in the range of 7% to 10% of the maximum flux, accounting for contributions from the most volatile components. To validate the output of our numerical simulations we compare the results of all three models to in situ gas number density measurements from the ROSINA COPS instrument. We are able to reproduce the overall features of these local neutral number density measurements of ROSINA COPS for the time period between early August 2014 and January 1 2015 with all three models. Some details in the measurements are not reproduced and warrant further investigation and refinement of the models. However, the overall assumption that illumination conditions on the nucleus are at least an important driver of the gas activity is validated by the models. According to our simulation results we find the total production rate of 67P to be constant between August and November 2014 with a value of about 1 × 10²⁶ molecules s⁻¹.

Ethical considerations for a global concept of sustainable land use

The paper gives an overview of current land husbandry problems in different agro-ecological zones of the world. It then lists four ethical principles, conceived at the global level, needed to achieve sustainable land use (SLU). Finally, it develops guidelines which can be used to facilitate a more effective implementation and realization of SLU. In the year of the UN Conference on Environment and Development (UNCED), such recommendations are important for improving the competence of political and economic decision-makers in taking action at national and international levels.

Sustainable Development Appraisal (SDA): A methodological tool for the participatory assessment of sustainability from local to regional planning levels

The term 'sustainable development' is receiving increasing attention in development co-operation and at the global level. However, practical tools which can help local users and multi-disciplinary teams to work together and apply this general concept at the local to regional levels have' emerged only very recently. This paper describes a tool called 'Sustainable Development Appraisal' (SDA), which is based on the principles of sustainable development, and can be applied by small interdisciplinary teams using a transdisciplinary approach, i.e. in participation with local land users and other stakeholders at various levels of intervention. The SDA has been applied in different parts of the globe. It is receiving considerable attention, and may fulfil most requirements contained in the concept of sustainable development, and yet be practically applicable and useful in the local to regional context. Examples from Eritrea and Ethiopia are used in this paper 'to illustrate the practicability of SDA for development planning and implementation.

Family Influence and Psychological Ownership: The Mediating Effects of Control

The concept of psychological ownership (PO) has been increasingly researched in the last years. However, knowledge about the emergence of PO is still scarce. So far, no study has investigated the development of PO in the context of family firms. We aim to investigate the emergence of PO in that context by drawing on the family´s influence on the business as a decisive factor. We thereby elaborate on the effect of family influence on PO, mediated by non-family managers´ perceived control over the company.
