A note on a first application of clustering procedures to fleet material condition measurements

The objective of this paper is to provide an independent evaluation of the nature and interpretation of ships' physical condition data generated by the USN Board of Inspection and Survey (INSURV). The substantive context is the classification of ships in terms of material condition and/or readiness based on scores pertaining to individual line elements within each ship. In order to account for multi-dimensional measures of each ship, clustering procedures are employed to evaluate existing ship classification systems and to indicate other possibilities.     

Middle Powers And The Demand For Military Expenditures

This paper identifies and classifies middle power nations through the use of broad political science definitions, the demand for military expenditures models and gross domestic product (GDP) per capita. The latter is used as a simple quantifiable measure of relative and potential military power. The paper also develops and utilizes a threat variable that is applicable to middle power nations. The panel data analysis shows that the middle power nations react to threat variables that proxy global instability utilize foreign aid as a complementary policy tool along with military expenditures, and face significant trade-offs between military and non-military government spending.     

White hull or white elephant? Soft power and the Chinese hospital ship,the Peace Ark

Although soft power is now seen as an indispensable foreign policy tool, its efficacy has rarely been put to a rigorous empirical test. Using data from HARMONIOUS MISSIONs 2010, 2011 and 2013, this article seeks to examine the degree to which the soft power engagement missions of the Chinese hospital ship, the Peace Ark, has advanced Chinese interests. Although any conclusions drawn must be considered preliminary, as so little time has passed between the ship's visits and the current analysis, this research indicates that these missions’ impact on advancing Chinese interests was at best limited. Although observations from a single set of cases are unlikely to settle the debate between soft power advocates and detractors, it is hoped that this research will serve as a catalyst to further empirically based research on this topic.     

Beyond the state: reconceptualising African security in the 21st century

Confronted with myriad security challenges, African states and the much-vaunted peace and security architecture of the African Union (AU) has proven not to be up to the challenge. Indeed, this is implicitly acknowledged by the AU itself if one considers the creation of such security structures as the African Mission in Somalia (AMISOM), which exists outside its peace and security architecture. This paper argues for a radical rethink of security structures on the African continent – one in which state structures of security coexist with newer forms of security actors, including private military companies (PMCs), community movements and the business sector. Whilst this shift in security actors is already happening on the ground, policymakers need to embrace this new reality.     

Lower confidence limits for the impact probability within a circle in the normal case

Lower confidence limits are derived for the impact probability within a circle of fixed radius. The bivariate normal distribution with zero means, unequal variances, and zero correlation is the probability model for impacts. A new representation of the impact probability function is offered. This presentation is valid also for the dependent case, where the eigenvalues of the covariance matrix replace the variances. When the ratio of variances is known the lower confidence limits are uniformly most accurate (UMA). A few alternative approaches are compared by simulation when the ratio of variances is unknown.     

Combating Islamist radicalisation in South Africa

Is radical Islamism spreading in South Africa? The answer has to be an emphatic ‘yes’. When discussing issues of radicalisation in Africa, commentators often examine the case of Somalia's al-Shabaab or al-Qaeda's North African franchise, al-Qaeda in the Islamic Maghreb (AQIM). Very little attention is paid to radicalisation amongst South Africa's Muslim population. Yet, there is growing evidence that South Africa has come to play an important role in global jihadi networks, from the provision of safehouses and identity documents to the movement of funds and the existence of paramilitary camps for local and foreign jihadis. This paper aims to briefly examine radicalisation and its attendant sources in the country, as well as seeking ways to combat it utilising lessons learned from other countries. ‘Institutional socialisation’ by means of the sources of radicalisation, as well as the concept of what could be termed ‘the democratisation of jihad’ are discussed. The author also proposes ways to combat radicalisation in South Africa utilising lessons learned from other countries, concluding that issues of radicalisation and deradicalisation have to be dealt with on the part of both government and the South African Muslim community.     

ACCRUAL BUDGETING AND DEFENCE FUNDING: THEORY AND SIMULATIONS

This paper explores the impact of moving to accrual budgeting on resources allocation in defence. Standard defence budgeting and investment models are used to assess the theoretical implications of accrual budgeting. In addition, a number of simulations are conducted to assess the long-term implications of moving to accrual accounting and budgeting. The result of the simulations shows that changes to deployed operations and other operational shocks will have manageable impacts on readiness but systematic shocks associated with defence unit prices, procurement policies and defence specific inflation will put considerable strain on the defence department's flexibility.
