Abstract
Purpose
When deploying a frigate to the Gulf of Aden as a part of the Operation Atalanta, the Norwegian Defence outsourced logistics to a TPL provider. The purpose of this paper is to explore the cooperation between the Defence and the TPL provider during the operation.
Design/methodology/approach
A qualitative design was chosen. Semi‐structured interviews were combined with relevant secondary sources. A theoretical framework formed the basis for the interviews.
Findings
No long‐term history existed between the parties before the cooperation, and no psychological contracts between individuals at tactical levels were made beforehand. Yet the cooperation was a success. It seems that this to a large degree depended on the individuals assigned to the project.
Research limitations/implications
The research highlights the need to address not only how to design physical supply structures but also how to ensure adequate levels of collaborative competence within civil‐military project groups. Further research is needed to investigate how to embed key suppliers in Defence logistics structures and how supply chains for short‐term, limited deployments impact on logistics arrangements for the permanent structure of the Defence.
Practical implications
This research gives the Norwegian Defence valuable knowledge about how to collaborate with commercial logistics providers.
Originality/value
This research highlights challenges when embedding suppliers into military supply chains. This is of importance not just when supplying deployed forces but also when considering supplier integration, e.g. through PPP and PBL.

Abstract
The design of aliasing-free space support hardware for built-in self-testing in very large scale integration circuits and systems is of immense significance, specifically due to the design paradigm shift in recent years from system-on-board to system-on-chip. This paper discusses approach to realizing aliasing-free space compaction hardware targeting particularly embedded cores-based system-on-chips for single stuck-line faults, extending well-known concept from conventional switching theory, viz. that of compatibility relation as used in the minimization of incompletely specified sequential machines. For a pair of response outputs of the circuit under test, the method introduces the notion of fault detection compatibility and conditional fault detection compatibility (conditional upon some other response output pair being simultaneously fault detection compatible) with respect to two-input AND/NAND, OR/NOR and XOR/XNOR logic, respectively. The process is illustrated with design details of space compactors for the International Symposium on Circuits and Systems or ISCAS 85 combinational (and ISCAS 89 full-scan sequential) benchmark circuits using simulation programs ATALANTA and FSIM, attesting to the relevance of the technique from the viewpoint of simplicity, resultant low area overhead and full fault coverage for single stuck-line faults, thereby making it an appropriate choice in commercial design environments.

Abstract
WHEN they decided to modernise their fleet of aeroplanes, the directors of Imperial Airways, Ltd decided on a bold policy of placing orders with two firms to build a series of machines each to their specification without waiting for trials with the first of each type before ordering subsequent aircraft. This decision has been amply justified in the results. The Handley‐Page 42 has shown itself to be one of the most comfortable and sound proof aeroplanes in the world, while the Armstrong‐Whitworth A.W.XV, the first of which has recently appeared, is most attractive in appearance and appears equally so in performance.

Abstract
Realizing aliasing-free space compressor for built-in self-testing of very large scale integration circuits and systems is of immense practical significance, especially due to the design paradigm shift in recent years from system-on-board to system-on-chip. This paper explores and provides new results on extending the scope of a recently developed approach to synthesizing aliasing-free space compaction hardware targeting particularly embedded cores-based system-on-chips for single stuck-line faults. For a pair of response outputs of the circuit under test, the method uses the notion of fault detection compatibility and conditional fault detection compatibility (conditional upon some other response output pair being simultaneously fault detection compatible) with respect to two-input AND/NAND nonlinear logic. The process is illustrated with development details of space compressors for the International Symposium on Circuits and Systems or ISCAS 85 combinational and ISCAS 89 full-scan sequential benchmark circuits (results on full-scan sequential circuits though not included in the paper) using simulation programs ATALANTA and FSIM, showing the relevance of the technique from the viewpoint of simplicity, resultant low area overhead and full fault coverage for single stuck-line faults, thereby making it an ideal choice in actual design environments.

Abstract
THE increasing speed of modern aircraft has brought to the forefront the necessity for making a careful drag analysis of all aircraft in order to separate out the essential drag, that is to say the drag that is unavoidable, from the non‐essential drag. Most designers, we believe, now do this in order to see what progress is being made in the streamlining of their products. By this means we are enabled to see the relative importance of the drag terms and to arrive at a figure of merit. The ideally‐streamline aeroplane, though not at present a precise proposition, is like other ideals unattainable. It is the standard to which designers may aspire, but which they cannot achieve.

Abstract
The design of space-efficient support hardware for built-in self-testing (BIST) is of immense significance in the synthesis of present day very large-scale integration (VLSI) circuits and systems, particularly in the context of design paradigm shift from system-on-board to system-on-chip (SOC). This paper presents an overview of the general problem of designing zero-aliasing or aliasing-free space compression hardware in relation to embedded cores-based SOC for single stuck-line faults in particular, extending the well-known concepts of conventional switching theory, and of incompatibility relation to generate maximal compatibility classes (MCCs) utilizing graph theory concepts, based on optimal generalized sequence mergeability, as developed by the authors in earlier works. The paper briefly presents the mathematical basis of selection criteria for merger of an optimal number of outputs of the module under test (MUT) for realizing maximum compaction ratio in the design, along with extensive simulation results on International Symposium on Circuits and Systems or ISCAS 85 combinational and ISCAS 89 full-scan sequential benchmark circuits, with simulation programs ATALANTA, FSIM, and COMPACTEST.

Abstract
Purpose
The World Food Program provides food aid to areas of the world where food security is poor or non-existent – often failed states. Food can be a weapon in such places and food aid shipments a target for capture. This paper investigates the cost-effectiveness of international efforts to protect World Food Program aid shipments destined for Somalia from seaborne pirates off the Horn of Africa.
Findings
The lessons of history were ignored by those attempting to prevent food aid shipments from falling into the hands of pirates. The international community initially used very expensive naval assets to protect shipments. Over time, in an effort to reduce costs, the strategy and assets used to secure shipments evolved. This slow, cost-reduction-driven evolution of the international community’s anti-piracy efforts off the Horn of Africa has distinct parallels with the evolution of anti-piracy efforts in the eighteenth and nineteenth centuries. One difference between the historic and current anti-piracy strategies is that there does not appear to be an exit strategy for the latter.
Practical implications
Future anti-piracy initiatives might look to previous strategies to avoid the costly experience associated with Somalia-bound food aid shipments.
Social implications
Achieving food security objectives can be a resource-intensive activity in failed states. This paper provides insights into how the resource cost of providing food security can be reduced.

Abstract
This chapter examines Francis Bacon’s influence on Émile Durkheim and demonstrates that Bacon’s theory of mental “idols” has a significant presence in Durkheim’s work. Both Bacon and Durkheim sought to demarcate new methods of inquiry against contemporary contenders. Both were wary of unfettered philosophical abstraction, as well as the pseudo-scientist’s preoccupation with immediately practical results. Thus, it is fitting that Durkheim would explicitly characterize perceived dangers to sociological knowledge in terms of Bacon’s idols – as objective obstacles which habit substitutes for fact in the absence of a sufficiently powerful epistemological mechanism. In preparation against these idols, Durkheim and Bacon offer rhetorically and logically similar remedies of self-imposed discipline and restraint. A close reading of key texts reveals that Durkheim’s references to Bacon capture surprisingly deep similarities, suggesting that Bacon influenced Durkheim to a greater degree than is commonly recognized.
