Just war and military morale: a brief reflection on the correlation between the legality of war and the moral repercussions for members of US and UK forces arising from the questionable legality of the campaign Iraqi Freedom of March 2003
Does it matter to a member of the military whether the military
campaign in which he is taking part is lawful or not? Despite the observation that
the crime of aggression (post Kampala 2010) constitutes a ‘leadership crime par
excellence,’ which limits any (future) criminal responsibility accordingly, the
legality or illegality of any military action under international law can create moral
implications for the common foot soldier and mid-level officer and also have a
tangible impact on the national legal frameworks under which these forces operate.
This short article uses the example of Operation Iraqi Freedom (2003) to discuss the repercussions of a—most likely—illegal military campaign for individual members
of democratic armed forces before the background of the present discussion of NATO led action in Libya
Satellite data relay and platform locating in oceanography. Report of the In Situ Ocean Science Working Group
The present and future use of satellites to locate offshore platforms and relay data from in situ sensors to shore was examined. A system of the ARGOS type will satisfy the increasing demand for oceanographic information through data relay and platform location. The improved ship navigation provided by the Global Positioning System (GPS) will allow direct observation of currents from underway ships. Ocean systems are described and demand estimates on satellite systems are determined. The capabilities of the ARGOS system is assessed, including anticipated demand in the next decade
Befriending and Re-ablement Service: A better alternative in an age of austerity
Purpose: The purpose of this paper is to share the findings of a research evaluation into a Befriending and Re-ablement Service (BARS) which offers a host of positive outcomes such as reduced loneliness and keeping as well as possible for a growing segment of the world’s population. The recent increase in longevity is one of humanity’s great success stories. But ageing comes at a price, and decision takers worry about the stresses and strains of an ageing society.
Design/methodology/approach: Following a literature review, this paper presents the findings of an evaluation of an alternative innovative form of support for older people, namely BARS, that has been developed on Merseyside. Semi- and unstructured interviews were carried out with stakeholders including service users and carers. A cost-benefit analysis is also reported. Finally the theoretical and policy implications of this research are explored.
Findings: Befriending and re-ablement officers is both a socially and economically cost effective means of enhancing independent living among older people, reducing loneliness and isolation that can contribute to ill health. The research shows that funding for the BARS scheme should be sustained and expanded, despite or because of the current era of cutbacks in UK and international service provision.
Originality/value: The paper highlights the value, role and importance of both befriending and re-ablement in a time of acute public and voluntary sector funding pressures. The paper is of value to a range of stakeholder groups such as older people, local and central governments and health care commissioners
Efficient Spin-Orbit Torques in an Antiferromagnetic Insulator with Tilted Easy Plane
Electrical manipulation of spin textures inside antiferromagnets represents a
new opportunity for developing spintronics with superior speed and high device
density. Injecting spin currents into antiferromagnets and realizing efficient
spin-orbit-torque-induced switching is however still challenging due to the
complicated interactions from different sublattices. Meanwhile, because of the
diminishing magnetic susceptibility, the nature and the magnitude of
current-induced magnetic dynamics remain poorly characterized in
antiferromagnets, whereas spurious effects further complicate experimental
interpretations. In this work, by growing a thin film antiferromagnetic
insulator, {\alpha}-Fe2O3, along its non-basal plane orientation, we realize a
configuration where an injected spin current can robustly rotate the N\'eel
vector within the tilted easy plane, with an efficiency comparable to that of
classical ferromagnets. The spin-orbit torque effect stands out among other
competing mechanisms and leads to clear switching dynamics. Thanks to this new
mechanism, in contrast to the usually employed orthogonal switching geometry,
we achieve bipolar antiferromagnetic switching by applying positive and
negative currents along the same channel, a geometry that is more practical for
device applications. By enabling efficient spin-orbit torque control on the
antiferromagnetic ordering, the tilted easy plane geometry introduces a new
platform for quantitatively understanding switching and oscillation dynamics in
antiferromagnets.Comment: 21 pages, 5 figure

Routes To the Renaissance for Pittsfield, MA
The goal of the Master of Regional Planning Studio is to develop a student’s techniques for collecting, analyzing, and synthesizing spatial and non-spatial data and then presenting that collective data in a manner (i.e., report, video, presentation, and charettes) that is understandable to academics, professionals, and the public. Planning Studio allows students to integrate knowledge from coursework and research, and apply such knowledge to resolving representative planning problems. At UMASS Amherst, these problems are found in neighborhood, rural, urban, and/or regional settings.
In the fall of 2015, the City of Pittsfield contracted the MRP Studio to create a vision plan to connect the goal’s of its Master Plan in 2009 to current development regulations that encourage development and redevelopment of an appropriate size, scale and design that meets the short term and long term vision of the community. The vision plan encompasses the following: Spatial and Physical Boundaries of Major Gateway Corridors: Analyze the major gateways and develop tools to make them more welcoming. Permitted Use Table and Definitions: Review, clarify, and consolidate the land-uses listed in the table to assess deficiencies and unclear definitions. Design Guidelines: Create a manual to guide architectural aesthetic standards for new retail developments. Sign Ordinance: Implement a streamlined regulation that improves sign quality. Site Plan Review: Develop thresholds to create clearer processes for review of development projects. Resolution for Split Parcels: Identify all properties that fall within two zoning districts and develop a mitigation tool. Pro Forma and Multi-Family Housing: Develop a financial model that will estimate the construction and maintenance cost of multi-family housing units and make projections for new development’s financial return
Fruit and vegetable consumption is associated with lower prevalence of asymptomatic diverticulosis: a cross-sectional colonoscopy-based study.
BACKGROUND: Previous studies of the relationship between dietary factors and risk of diverticulosis have yielded inconsistent results. We therefore sought to investigate the association between consumption of fruit and vegetables and prevalent diverticulosis.
METHODS: Our study population included participants in the Gastrointestinal Disease and Endoscopy Registry (GIDER), a colonoscopy-based longitudinal cohort at the Massachusetts General Hospital, who provided comprehensive information on dietary intake and lifestyle factors using validated questionnaires prior to colonoscopy. Information on presence and location of diverticula was obtained from the endoscopist at the end of each procedure. We used Poisson regression modeling to calculate the prevalence ratios (PRs) and 95% confidence intervals (CIs).
RESULTS: Among 549 participants with a mean age of 61 years enrolled in GIDER, we confirmed diverticulosis in 245 (44.6%). The prevalence of diverticulosis appeared to decrease with higher consumption of fruit and vegetables (P
CONCLUSION: In a colonoscopy-based longitudinal cohort study, we show that higher consumption of fruit and vegetables is associated with lower risk of prevalent diverticulosis
Overexpression of human wild-type FUS causes progressive motor neuron degeneration in an age- and dose-dependent fashion
Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are relentlessly progressive neurodegenerative disorders with overlapping clinical, genetic and pathological features. Cytoplasmic inclusions of fused in sarcoma (FUS) are the hallmark of several forms of FTLD and ALS patients with mutations in the FUS gene. FUS is a multifunctional, predominantly nuclear, DNA and RNA binding protein. Here, we report that transgenic mice overexpressing wild-type human FUS develop an aggressive phenotype with an early onset tremor followed by progressive hind limb paralysis and death by 12 weeks in homozygous animals. Large motor neurons were lost from the spinal cord accompanied by neurophysiological evidence of denervation and focal muscle atrophy. Surviving motor neurons in the spinal cord had greatly increased cytoplasmic expression of FUS, with globular and skein-like FUS-positive and ubiquitin-negative inclusions associated with astroglial and microglial reactivity. Cytoplasmic FUS inclusions were also detected in the brain of transgenic mice without apparent neuronal loss and little astroglial or microglial activation. Hemizygous FUS overexpressing mice showed no evidence of a motor phenotype or pathology. These findings recapitulate several pathological features seen in human ALS and FTLD patients, and suggest that overexpression of wild-type FUS in vulnerable neurons may be one of the root causes of disease. Furthermore, these mice will provide a new model to study disease mechanism, and test therapies
SARS-CoV-2 positivity in asymptomatic-screened dental patients
Enhanced community surveillance is a key pillar of the public health response to COVID-19. Asymptomatic carriage of SARS-CoV-2 is a potentially significant source of transmission, yet remains relatively poorly understood. Disruption of dental services continues with significantly reduced capacity. Ongoing precautions include pre- and/or at appointment COVID-19 symptom screening and use of enhanced personal protective equipment (PPE). This study aimed to investigate SARS-CoV-2 infection in dental patients to inform community surveillance and improve understanding of risks in the dental setting. Thirty-one dental care centres across Scotland invited asymptomatic screened patients over 5-years-old to participate. Following verbal consent and completion of sociodemographic and symptom history questionnaire, trained dental teams took a combined oropharyngeal and nasal swab sample using standardised VTM-containing testkits. Samples were processed by the Lighthouse Lab and patients informed of their results by SMS/e-mail with appropriate self-isolation guidance in the event of a positive test. All positive cases were successfully followed up by the national contact tracing program. Over a 13-week period (from 3August to 31October2020) n=4,032 patients, largely representative of the population, were tested. Of these n=22 (0.5%; 95%CI 0.5%, 0.8%) tested positive for SARS-CoV-2. The positivity rate increased over the period, commensurate with uptick in community prevalence identified across all national testing monitoring data streams. To the best of our knowledge this is the first report of a COVID-19 testing survey in asymptomatic-screened patients presenting in a dental setting. The positivity rate in this patient group reflects the underlying prevalence in community at the time. These data are a salient reminder, particularly when community infection levels are rising, of the importance of appropriate ongoing Infection Prevention Control and PPE vigilance, which is relevant as healthcare team fatigue increases as the pandemic continues. Dental settings are a valuable location for public health surveillance
