Political Speech in the Armed Forces: Shouting Fire in a Crowded Cyberspace

A staple of the American version of democracy is civilian control of the military: we are uncomfortable with politicization of the Armed Forces, and military and other federal laws restrict the political expression of servicemembers (“SMs”) in the Armed Forces, whether they are active- duty members or National Guard or Reserves serving on active duty. These restrictions, while well-intentioned to prevent actual or apparent political partisanship or bias within the military, have the undesired effect of deterring SMs from otherwise healthy political expression. With the advent of the internet and proliferation of social media use, questions regarding SM status and identification with the military complicate the political participation of citizen-soldiers. The presence of over-reaching restrictions on political expression and lack of clear guidance dictating what political expression SMs can and cannot make in online forums have several effects. First, this framework of acceptable political discourse contributes to a breakdown of the ‘citizen-soldier’ ideal that is peculiar to the American conception of military service in a democracy. Second, this framework tends to deprive SMs of their personal and political autonomy in a manner that tends to reduce them to a position of vassalage. Third, this reinforces the ‘tyranny of majority opinion’ that John Stuart Mill presciently warned of at a time when militaries were professionalizing. Lastly, this framework contributes to the isolation of the military from general society by removing military voices from the ‘marketplace of ideas,’ thereby depriving the public discourse of a crucial segment of the American population. While partisan political expression in online forums is a relatively new phenomenon, it is merely an extension of every citizen’s right to engage in public debate, and to the extent that SMs are prohibited or deterred from political expression through legal restrictions rather than professional and ethical norms, their right to exercise the duties of citizenship is infringed, to their detriment and that of the body politic

Strategy, operations, and profitability: The role of resource orchestration

Purpose – Developing and implementing strategies to maximize profitability is a fundamental challenge facing manufacturers. The complexity of orchestrating resources in practice has been overlooked in the operations field and it is now necessary to go beyond the direct effects of individual resources and uncover different resource configurations that maximize profitability. Design/methodology/approach – Drawing on a sample of US manufacturing firms, multiple regression analysis (MRA) and fuzzy-set Qualitative Comparative Analysis (fsQCA) are performed to examine the effects of resource orchestration on firm profitability over time. By comparing the findings between analyses, the study represents a move away from examining the net effects of resource levers on performance alone. Findings – The findings characterize the resource conditions for manufacturers’ high performance, and also for absence of high performance. Pension and retirement expense is a core resource condition with R&D and SG&A as consistent peripheral conditions for profitability. Moreover, although workforce size was found to have a significant negative effect under MRA, this plays a role in manufacturers’ performance as a peripheral resource condition under fsQCA. Originality/value – Accounting for different resource deployment configurations, this study deepens knowledge of resource orchestration and presents findings that enable manufacturers to maximize profitability. An empirical contribution is offered by the introduction of a new method for examining manufacturing strategy configurations: fsQCA

The role of stripe orientation in target capture success.

INTRODUCTION: 'Motion dazzle' refers to the hypothesis that high contrast patterns such as stripes and zigzags may have evolved in a wide range of animals as they make it difficult to judge the trajectory of an animal in motion. Despite recent research into this idea, it is still unclear to what extent stripes interfere with motion judgement and if effects are seen, what visual processes might underlie them. We use human participants performing a touch screen task in which they attempt to 'catch' moving targets in order to determine whether stripe orientation affects capture success, as previous research has suggested that different stripe orientations may be processed differently by the visual system. We also ask whether increasing the number of targets presented in a trial can affect capture success, as previous research has suggested that motion dazzle effects may be larger in groups. RESULTS: When single targets were presented sequentially within each trial, we find that perpendicular and oblique striped targets are captured at a similar rate to uniform grey targets, but parallel striped targets are significantly easier to capture. However, when multiple targets are present simultaneously during a trial we find that striped targets are captured in fewer attempts and more quickly than grey targets. CONCLUSIONS: Our results suggest that there may be differences in capture success based on target pattern orientation, perhaps suggesting that different visual mechanisms are involved in processing of parallel stripes compared to perpendicular/oblique stripes. However, these results do not seem to generalise to trials with multiple targets, and contrary to previous predictions, striped targets appear to be easier to capture when multiple targets are present compared to being presented individually. These results suggest that the different orientations of stripes seen on animals in nature (such as in fish and snakes) may serve different purposes, and that it is unclear whether motion dazzle effects may have greater benefits for animals living in groups.We thank the subjects who volunteered to take part in these experiments.AEH was supported by a BBSRC CASE studentship and MS was supported by a Biotechnology and Biological Sciences Research Council (BBSRC) David Phillips Research Fellowship (BB/G022887/1).This is the final version of the article.

A Bayesian localised conditional auto-regressive model for estimating the health effects of air pollution

Estimation of the long-term health effects of air pollution is a challenging task, especially when modeling spatial small-area disease incidence data in an ecological study design. The challenge comes from the unobserved underlying spatial autocorrelation structure in these data, which is accounted for using random effects modeled by a globally smooth conditional autoregressive model. These smooth random effects confound the effects of air pollution, which are also globally smooth. To avoid this collinearity a Bayesian localized conditional autoregressive model is developed for the random effects. This localized model is flexible spatially, in the sense that it is not only able to model areas of spatial smoothness, but also it is able to capture step changes in the random effects surface. This methodological development allows us to improve the estimation performance of the covariate effects, compared to using traditional conditional auto-regressive models. These results are established using a simulation study, and are then illustrated with our motivating study on air pollution and respiratory ill health in Greater Glasgow, Scotland in 2011. The model shows substantial health effects of particulate matter air pollution and nitrogen dioxide, whose effects have been consistently attenuated by the currently available globally smooth models

From Citywide to Neighborhood-Based: Two Decades of Learning, Prioritization, and Strategic Action to Build the Skillman Foundation’s Youth-Development Systems

· This article explores the Skillman Foundation’s shift in its approach to fulfilling its mission to improve the lives of children and youth and to making grants – moving from a traditional grantmaker to a place-based investor and change-maker. · Three aspects of Skillman’s approach have directly shaped the evolution of its youth-development investments: recognizing Detroit’s economic, social, political, and environmental challenges; articulating overarching goals to provide direction and setting priorities for the scope and focus of its programmatic work; and using rapid learning to inform strategic decisions and social-innovation practices designed to tackle deeply entrenched problems. · This article reflects on the foundation’s evolution over two decades of learning, prioritization, and strategic action in its efforts to build and sustain outcome-focused youth-development systems

Partial differential equation models for invasive species spread in the presence of spatial heterogeneity

Models of invasive species spread often assume that landscapes are spatially homogeneous; thus simplifying analysis but potentially reducing accuracy. We extend a recently developed partial differential equation model for invasive conifer spread to account for spatial heterogeneity in parameter values and introduce a method to obtain key outputs (e.g. spread rates) from computational simulations. Simulations produce patterns of spatial spread remarkably similar to observed patterns in grassland ecosystems invaded by exotic conifers, validating our spatially explicit strategy. We find that incorporating spatial variation in different parameters does not significantly affect the evolution of invasions (which are characterised by a long quiescent period followed by rapid evolution towards to a constant rate of invasion) but that distributional assumptions can have a significant impact on the spread rate of invasions. Our work demonstrates that spatial variation in site-suitability or other parameters can have a significant impact on invasionsComment: 13 pages, 18 figure
