Medical emergencies on international flights are not uncommon. In these situations the question often arises whether physicians are obliged to render first aid and whether omission leads to legal consequences. The general obligation to aid those in need applies to everyone, not only to physicians. Evading this duty makes liable to prosecution for omittance of defence of a third person in line with Art. 128 of the Swiss Penal Code, punishable by custodial sentence up to three years or an equivalent punitive fine. Vocational and professional law extend the duty to aid for physicians to urgent cases. Although resulting from the performance of a legal obligation, malpractice occurred in the course of first aid can lead to claims for compensation - even from foreign patients, and that according to their own domestic law.

Considering that endemic hunger is a consequence of poverty, and that food is arguably the most basic of all human needs, this book chapter shows one of the more prominent examples of rules and policy fragmentation but also one of the most blatant global governance problems. The three monotheistic religions Judaism, Christians and Islam are surprisingly unanimous about God’s prescriptions on hunger or, put theologically, on what can be said, or should be said, about the interpretations and traditions which, taken together, form the respective and differentiated traditions, identities and views of these beliefs on how to deal with poverty and hunger. A clear social ethos, in the form of global needs satisfaction, runs through both Jewish and Christian texts, and the Qur’an (Zakat). It confirms the value inversion between the world of the mighty and that of the hungry. The message is clear: because salvation is available only through the grace of God, those who have must give to those who have not. This is not charity: it is an inversion of values which can not be addressed by spending 0.7% of your GDP on ODA, and the implication of this sense of redistributive justice is that social offenders will be subject to the Last Judgement. Interestingly, these religious scriptures found their way directly into the human rights treaties adopted by the United Nations and ratified by the parliaments, as a legal base for the duty to protect, to respect and to remedy. On the other side the contradiction with international trade law is all the more flagrant, and it has a direct bearing on poverty: systematic surplus food dumping is still allowed under WTO rules, despite the declared objective ‘to establish a fair and market-oriented agricultural trading system’. A way forward would be a kind of ‘bottom up’ approach by focusing on extreme cases of food insecurity caused by food dumping, or by export restrictions where a direct effect of food insecurity in other countries can be established. Also, international financing institutions need to review their policies and lending priorities. The same goes for the bilateral investment treaties and a possible ‘public interest’ clause, at least in respect of agricultural land acquisitions in vulnerable countries. The bottom line is this: WTO rules cannot entail a right to violate other, equally binding treaty obligations when its membership as a whole claims to contribute to the Millennium Development Goals and pledges to eradicate extreme poverty and hunger.

Energy is of primary concern in wireless sensor networks (WSNs). Low power transmission makes the wireless links unreliable, which leads to frequent topology changes. Resulting packet retransmissions aggravate the energy consumption. Beaconless routing approaches, such as opportunistic routing (OR) choose packet forwarders after data transmissions, and are promising to support dynamic features of WSNs. This paper proposes SCAD - Sensor Context-aware Adaptive Duty-cycled beaconless OR for WSNs. SCAD is a cross-layer routing solution and it brings the concept of beaconless OR into WSNs. SCAD selects packet forwarders based on multiple types of network contexts. To achieve a balance between performance and energy efficiency, SCAD adapts duty-cycles of sensors based on real-time traffic loads and energy drain rates. We implemented SCAD in TinyOS running on top of Tmote Sky sensor motes. Real-world evaluations show that SCAD outperforms other protocols in terms of both throughput and network lifetime.

Low quality of wireless links leads to perpetual transmission failures in lossy wireless environments. To mitigate this problem, opportunistic routing (OR) has been proposed to improve the throughput of wireless multihop ad-hoc networks by taking advantage of the broadcast nature of wireless channels. However, OR can not be directly applied to wireless sensor networks (WSNs) due to some intrinsic design features of WSNs. In this paper, we present a new OR solution for WSNs with suitable adaptations to their characteristics. Our protocol, called SCAD-Sensor Context-aware Adaptive Duty-cycled beaconless opportunistic routing protocol is a cross-layer routing approach and it selects packet forwarders based on multiple sensor context information. To reach a balance between performance and energy-efficiency, SCAD adapts the duty-cycles of sensors according to real-time traffic loads and energy drain rates. We compare SCAD against other protocols through extensive simulations. Evaluation results show that SCAD outperforms other protocols in highly dynamic scenarios.
