Policing, rule of law, state capacity and sustainable peace in Timor-Leste

This paper sets out to demonstrate the link between development, state capacity and peace, employing Timor-Leste as the case study. It employs the association between state capacity and development to illustrate where if state capacity is lacking or functions improperly there is likely to be a low level of state legitimacy. This in turn manifests as lack of respect for or failure of rule of law, developing as generalised lawlessness and anti-state activity and eventually manifesting as intra-state or civil conflict. In particular, policing is seen as a critical component in state legitimacy, being the 'front line' of the judicial system from which legitimacy ultimately derives. This issue is particularly critical in states emerging from traditional legal and judicial structures, but which have not yet articulated into 'rational-legal' structures. Ipso facto, key state institutions, such as the judicial system and police are required to function well, while these are alone not enough to guarantee peace, they are significant contributors to and guarantors of peace.

The effect of resistance training on functional capacity and quality of life in individuals with high and low number of metabolic risk factors

OBJECTIVE—There are limited data on the effects of resistance training on the capacity to perform activities of daily living (ADLs) and quality of life (QoL) for individuals with a high number of metabolic risk factors (HiMF). In this study, we examined the effect of resistance training on the capacity to perform ADLs and QoL in individuals with HiMF and compared any benefits with individuals with a low number of metabolic risk factors (LoMF).

RESEARCH DESIGN AND METHODS—Fifty-five untrained individuals, aged 50.8 ± 6.5 years, were randomized to four groups: HiMF training (HiMFT), HiMF control, LoMF training (LoMFT), and LoMF control. At baseline and after 10 weeks of resistance training, participants underwent anthropometric measurements and assessments of aerobic power (Vo2peak), muscle strength, capacity to perform ADLs, and a self-perceived QoL questionnaire. A repeated-measures ANOVA was used to examine the effect of training over time among groups.

RESULTS—Training increased lean body mass in both HiMFT (P = 0.03) and LoMFT (P = 0.03) groups. Total fat content and Vo2peak improved in the LoMFT group only. Muscle strength improved in both training groups (P < 0.01). Time to complete ADLs was reduced by 8.8% in the LoMFT group (P < 0.01) and 9.7% in the HiMF group (P < 0.01). Only the HiMFT group reported improvement in QoL.

CONCLUSIONS— Resistance training improved muscle strength and the capacity to perform ADLs in individuals with HiMF and LoMF. Resistance training improved QoL for the HiMF group, and this result was independent of changes in body fat content or aerobic power. Longer training regimens may be needed to improve QoL in individuals with LoMF.

Functional capacity and quality of life in middle-age men and women with high and low number of metabolic risk factors

It is not clear if men and women with high numbers of risk factors (HiMF) for metabolic syndrome (MetS) have impaired capacities to perform activities of daily living (ADL's) and lower quality of life (QoL) in the absence of symptomatic heart disease. Our results indicate that in women there is a correlation between the number of risk factors and the capacity to perform ADL's and QoL. This was not evident for men. These findings may partly explain why women tend to consult healthcare practitioners earlier in the disease process than men.

Reduced exercise tolerance in CHF may be related to factors other than impaired skeletal muscle oxidative capacity

Background : We sought to determine whether skeletal muscle oxidative capacity, fiber type proportions, and fiber size, capillary density or muscle mass might explain the impaired exercise tolerance in chronic heart failure (CHF). Previous studies are equivocal regarding the maladaptations that occur in the skeletal muscle of patients with CHF and their role in the observed exercise intolerance.

Methods and results : Total body O₂ uptake (VO_2peak) was determined in 14 CHF patients and 8 healthy sedentary similar-age controls. Muscle samples were analyzed for mitochondrial adenosine triphosphate (ATP) production rate (MAPR), oxidative and glycolytic enzyme activity, fiber size and type, and capillary density. CHF patients demonstrated a lower VO_2peak (15.1±1.1 versus 28.1±2.3 mL·kg⁻¹·min⁻¹, P<.001) and capillary to fiber ratio (1.09±0.05 versus 1.40±0.04; P<.001) when compared with controls. However, there was no difference in capillary density (capillaries per square millimeter) across any of the fiber types. Measurements of MAPR and oxidative enzyme activity suggested no difference in muscle oxidative capacity between the groups.

Conclusions : Neither reductions in muscle oxidative capacity nor capillary density appear to be the cause of exercise limitation in this cohort of patients. Therefore, we hypothesize that the low VO_2peak observed in CHF patients may be the result of fiber atrophy and possibly impaired activation of oxidative phosphorylation.

Client leadership capacity on international projects : exploring the client's complex decision-making environment through a critical cultural political economy lens

The global construction environment offers stakeholders a range of opportunities but is characterised by a high level of risks and uncertainty. Internationalisation is a relatively new field of research in the AEC sector and past research has largely focused on explaining the behaviour of the industry itself. To date there has been little research investigating the client's leadership role. Much effort has been placed on positioning clients towards overall industry performance improvement, however, with little emphasis on the client's capacity to undertake their role. Clients establish the decision-making environment through key early critical decisions including procurement strategy and team membership. To a large extent they establish a unique culture that project team members need to work within and make decisions, which is the social and cultural embedding of the economic activities on projects. This theoretical paper is positioned within a PhD study which undertakes a cultural political economy perspective to investigate the client's central role in setting the boundaries within which decisions affecting budgets, quality, design, project organisational structure and team membership throughout the project lifecycle come to be made. A conceptual model for client leadership on international projects is developed based upon two contextual indicators which seeks to describe and explain the economic decisions clients make, which are deeply embedded in social relationships, shared meanings and cultural norms and the associated power and influence clients have on the political economy of international design and construction practice. This paper also seeks to develop a research question for future empirical testing.

MoO3 nanoparticles dispersed uniformly in carbon matrix : a high capacity composite anode for Li-ion batteries

A MoO₃-carbon nanocomposite was synthesized from a mixture of MoO₃ and graphite by a controlled ball milling procedure. The as-prepared product consists of nanosized MoO₃ particles (2-180 nm) homogeneously distributed in carbon matrix. The nanocomposite acts as a high capacity anode material for lithium-ion batteries and exhibits good cyclic behavior. Its initial capacity exceeds the theoretical capacity of 745 mA h g^-1 in a mixture of MoO₃ and graphite (1:1 by weight), and the stable capacity of 700 mA h g^-1 (94% of the theoretical capacity) is still retained after 120 cycles. The electrode performance is linked with the unique nanoarchitecture of the composite and is compared with the performance of MoO₃-based anode materials reported in the literature previously (nanoparticles, ball milled powders, and carbon-coated nanobelts). The high value of capacity and good cyclic stability of MoO₃-carbon nanocomposite are attractive in respect to those of the reported MoO₃ electrodes.
