The Reliability and Predictive Ability of the Movement Competency Screen in a Military Population

Purpose: Musculoskeletal injuries in the United States Armed Forces impacts operational readiness. Therefore, a reliable, valid screening tool that identifies injury risk and predicts performance is needed. The purpose of this study was to: (1) establish the intra- and inter-rater reliability of the Movement Competency Screen (MCS) using a cohort of United States Naval Academy fourth class Midshipmen, (2) identify if a correlation exists between average total MCS scores and injury rates during training, and (3) identify if a correlation exists between 1/16 average total MCS score and performance on the Physical Readiness Test (PRT). Methods: Five raters independently evaluated 41 digital recordings of subjects who performed the MCS. An intraclass correlation (ICC) of 0.9 (95% CI) was used to determine raters’ reliability and a Spearman’s Correlation Coefficient examined relationships between average initial total MCS score with both (1) injury data and (2) PRT scores. Results: Raters demonstrated good inter-rater reliability (ICC = 0.88, 95% CI: 0.81-0.93), and moderate to good intra-rater reliability (ICC = 0.63-0.89) for total MCS scores. The average total MCS scores did not correlate with the total number of injuries sustained. However, a moderate positive correlation (r = 0.48; p = 0.003) was observed between average total MCS score and overall PRT scores for all subjects. For only female subjects, a very strong correlation was observed between average total MCS score and (1) overall PRT scores (r = 0.83; p = 0.00), (2) increased number of push-ups (r = 0.76; p = 0.001), and (3) slower runtimes (r = – 0.84; p = 0.00). These relationships were non-significant for male subjects. Conclusions: The high reliability reported is similar to Reid et al. 2015. The initial MCS score correlates with PRT performance for female subjects, but not males. However, the MCS score did not predict injury incidence in this cohort. Practical Application: Given the high reliability, the MCS may be a useful screening tool for the U.S. Armed Forces to identify recruits with poor movement competency, likely impacting poor performance on the PRT. Future research will examine the relationship, if present, between total MCS score and injury risk in this cohort

Quinolone signaling in the cell-to-cell communication system of Pseudomonas aeruginosa

Numerous species of bacteria use an elegant regulatory mechanism known as quorum sensing to control the expression of specific genes in a cell-density dependent manner. In Gram-negative bacteria, quorum sensing systems function through a cell-to-cell signal molecule (autoinducer) that consists of a homoserine lactone with a fatty acid side chain. Such is the case in the opportunistic human pathogen Pseudomonas aeruginosa, which contains two quorum sensing systems (las and rhl) that operate via the autoinducers, N-(3-oxododecanoyl)-L-homoserine lactone and N-butyryl-Lhomoserine lactone. The study of these signal molecules has shown that they bind to and activate transcriptional activator proteins that specifically induce numerous P. aeruginosa virulence genes. We report here that P. aeruginosa produces another signal molecule, 2-heptyl-3-hydroxy-4-quinolone, which has been designated as the Pseudomonas quinolone signal. It was found that this unique cell-to-cell signal controlled the expression of lasB, which encodes for the major virulence factor, LasB elastase. We also show that the synthesis and bioactivity of Pseudomonas quinolone signal were mediated by the P. aeruginosa las and rhl quorum sensing systems, respectively. The demonstration that 2-heptyl-3- hydroxy-4-quinolone can function as an intercellular signal sheds light on the role of secondary metabolites and shows that P. aeruginosa cell-to-cell signaling is not restricted to acyl-homoserine lactones.

'A habitual disposition to the good': on reason, virtue and realism

Amidst the crisis of instrumental reason, a number of contemporary political philosophers including Jürgen Habermas have sought to rescue the project of a reasonable humanism from the twin threats of religious fundamentalism and secular naturalism. In his recent work, Habermas defends a post-metaphysical politics that aims to protect rationality against encroachment while also accommodating religious faith within the public sphere. This paper contends that Habermas’ post-metaphysical project fails to provide a robust alternative either to the double challenge of secular naturalism and religious fundamentalism or to the ruthless instrumentalism that underpins capitalism. By contrast with Habermas and also with the ‘new realism’ of contemporary political philosophers such as Raymond Geuss or Bernard Williams, realism in the tradition of Plato and Aristotle can defend reason against instrumental rationality and blind belief by integrating it with habit, feeling and even faith. Such metaphysical–political realism can help develop a politics of virtue that goes beyond communitarian thinking by emphasising plural modes of association (not merely ‘community’), substantive ties of sympathy and the importance of pursuing goodness and mutual flourishing

Academic freedom: in justification of a universal ideal

This paper examines the justification for, and benefits of, academic freedom to academics, students, universities and the world at large. The paper surveys the development of the concept of academic freedom within Europe, more especially the impact of the reforms at the University of Berlin instigated by Wilhelm von Humboldt. Following from this, the paper examines the reasons why the various facets of academic freedom are important and why the principle should continue to be supported

The utilisation of health research in policy-making: Concepts, examples and methods of assessment

The importance of health research utilisation in policy-making, and of understanding the mechanisms involved, is increasingly recognised. Recent reports calling for more resources to improve health in developing countries, and global pressures for accountability, draw greater attention to research-informed policy-making. Key utilisation issues have been described for at least twenty years, but the growing focus on health research systems creates additional dimensions. The utilisation of health research in policy-making should contribute to policies that may eventually lead to desired outcomes, including health gains. In this article, exploration of these issues is combined with a review of various forms of policy-making. When this is linked to analysis of different types of health research, it assists in building a comprehensive account of the diverse meanings of research utilisation. Previous studies report methods and conceptual frameworks that have been applied, if with varying degrees of success, to record utilisation in policy-making. These studies reveal various examples of research impact within a general picture of underutilisation. Factors potentially enhancing utilisation can be identified by exploration of: priority setting; activities of the health research system at the interface between research and policy-making; and the role of the recipients, or 'receptors', of health research. An interfaces and receptors model provides a framework for analysis. Recommendations about possible methods for assessing health research utilisation follow identification of the purposes of such assessments. Our conclusion is that research utilisation can be better understood, and enhanced, by developing assessment methods informed by conceptual analysis and review of previous studies

Clarifying anti-reflexivity: Conservative opposition to impact science and scientific evidence

The recent study reported by McCright et al (2013 Environ. Res. Lett. 8 044029) extends current research on conservatives' distrust of science by distinguishing between public trust in production versus impact scientists (i.e. those whose work yields new technologies and marketable products versus those assessing the health and environmental impacts of such technologies and products). As expected, they find that conservatives are significantly less trustful of impact scientists but somewhat more trustful of production scientists. In the process they provide support for the Anti-Reflexivity Thesis, a perspective that attributes conservatives' (and Republicans') denial of anthropogenic climate change (ACC) and other environmental problems and attacks on climate/environmental science to their staunch commitment to protecting the current system of economic production. McCright et al's innovative study deserves replication, and their approach should prove useful in accounting for divergent views of ACC. It is also important to keep in mind that anti-reflexivity is an institutional and structural issue, becoming more consequential when it is employed by political elites such as the George W Bush Administration in the US. Institutional anti-reflexivity is further illustrated by the widespread denial of ACC and a range of other problems among current Republican members of the US Congress.Peer reviewedSociolog

Postsecular planning? The idea of municipal spirituality

© 2015 Taylor & Francis. In the contemporary political context, religion is rarely out of the news, usually postulated as a regressive force, battling against modern liberal Western values. However, in everyday life, and specifically with regard to place value, the situation is more complex. This paper addresses the challenge this context and the attendant notion of postsecularism bring to planning practice. It argues that religious and spiritual values can be rearticulated as concepts which add a substantive positive dimension to planning and its conceptualisation and constructions of place. This is done by developing the notion of municipal spirituality, which draws on the theological conceptions of transcendence and the common good to redefine the value of places whose worth cannot easily be made in instrumental terms. In so doing, it challenges the current antagonistic opposition of religious and liberal democratic values, repositioning religious and spiritual concepts in an inclusive way. The idea of municipal spirituality illustrates how planning could have a role in defending and promoting such places. Further, it demonstrates the importance of engaging in agonistic rather than antagonistic debate, rearticulating the criteria on which places can be valued by planning practice

The meta-crisis of secular capitalism

The current global economic crisis concerns the way in which contemporary capitalism has turned to financialisation as a double cure for both a falling rate of profit and a deficiency of demand. Although this turning is by no means unprecedented, policies of financialisation have depressed demand (in part as a result of the long-term stagnation of average wages) while at the same time not proving adequate to restore profits and growth. This paper argues that the current crisis is less the ‘normal’ one that has to do with a constitutive need to balance growth of abstract wealth with demand for concrete commodities. Rather, it marks a meta-crisis of capitalism that is to do with the difficulties of sustaining abstract growth as such. This meta-crisis is the tendency at once to abstract from the real economy of productive activities and to reduce everything to its bare materiality. By contrast with a market economy that binds material value to symbolic meaning, a capitalist economy tends to separate matter from symbol and reduce materiality to calculable numbers representing ‘wealth’. Such a conception of wealth rests on the aggregation of abstract numbers that cuts out all the relational goods and the ‘commons’ on which shared prosperity depends

How to speak of God? Toward a postsecular apologetics

This is an Accepted Manuscript of an article published by Taylor & Francis in Practical Theology on 11/04/2018, available online: https://www.tandfonline.com/doi/full/10.1080/1756073X.2018.1460522Against most expectations religion has not vanished from Western culture. If anything, it exercises a greater fascination than ever before. Broadly, we might think of ourselves as occupying a new, 'postsecular' space between a renewed visibility of religion in public life, and a corresponding acknowledgement of the importance of religious values and actors; and persistent and widespread disillusion and scepticism towards religion, and objections to religion as a source of legitimate public discourse. In a world that is more sensitive than ever to religious belief and practice, yet often struggles to accommodate it into secular discourse, how do religious institutions justify their position in a contested and volatile public square? This article argues that the contemporary postsecular context requires a recovery of the ancient practices of Christian apologetics as a form of public, theological witness to the practical value of faith, articulated in both deed and word
