Cooperative security management for broadband network environments
Authors: Cruz Tiago , Simões Paulo , Monteiro Edmundo , Bastos Fernando , Laranjeira Alexandre 
Published: July 2015

AbstractFrom an internet service provider's (ISP) perspective, modern broadband access networks pose significant and ever increasing challenges in terms of security management. The growing number of permanently connected home networks, with a myriad of poorly managed devices, imposes significant security risks not only to the domestic customers, unable to defend themselves from security attacks, but also to the ISP and third‐parties potentially targeted by large‐scale distributed botnet attacks fed by swarms of zombie domestic personal computers. In this context, the traditional delimitation of customer and ISP perimeters is no longer effective. Home networks became too complex and vulnerable to be autonomously managed by the average customer, and the scale and sophistication of distributed security attacks make it more and more difficult for the ISP to properly manage security without intervening outside the boundaries of its own network. Considering this state of affairs, we propose an alternative architecture for security management. This architecture increases the level of integration and cooperation between the domains of the ISP infrastructure and the home network. At the same time, it potentially improves the scalability and granularity of traditional intrusion detection and prevention mechanisms. Copyright © 2015 John Wiley & Sons, Ltd.

The Boreal Plains Ecozone (BPE) in Western Canada is expected to be an area of maximum ecological sensitivity in the 21st century. Successful climate adaptation and sustainable forest management require a better understanding of the interactions between hydrology, climate, and vegetation. This paper provides a perspective on the changing water cycle in the BPE from an interdisciplinary team of researchers, seeking to identify the critical knowledge gaps. Our review suggests the BPE will likely become drier and undergo more frequent disturbance and shifts in vegetation. The forest will contract to the north, though the southern boundary of the ecotone will remain in place. We expect detrimental impacts on carbon sequestration, water quality, wildlife, and water supplies. Ecosystem interactions are complex, and many processes are affected differently by warming and drying, thus the degree and direction of change is often uncertain. However, in the short term at least, human activities are the dominant source of change and are unpredictable but likely decisive. Current climate, hydrological, and ecological monitoring in the BPE are limited and inadequate to understand and predict the complex responses of the BPE to human activities and climate change. This paper provides a case study of how hydrological processes critically determine ecosystem functioning, and how our ability to predict system response is limited by our ability to predict changing hydrology.

The Role of Neighborhood in the Development of Aggression in Urban African American Youth: A Multilevel Analysis
Authors: Romero Edna , Richards Maryse H. , Harrison Patrick R. , Garbarino James , Mozley Michaela 
Published: July 2015

AbstractThe purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low‐income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.
Antioxidant Activities and Phenolic Compositions of Wheat Germ as Affected by the Roasting Process

Published: July 2015

AbstractWheat germ is a good source for wheat germ oil, and it is a by‐product with highly concentrated nutrients from the wheat flour‐milling industries. In the present study, raw wheat germ was firstly heat‐treated at 180 °C for 20 min in a fluidized bed dryer, and further roasted at 180 °C for different periods of time. Roasting influence on total phenolic content (TPC), antioxidant activities, and phenolic compositions of wheat germ were evaluated. The roasting process significantly increased the TPC and antioxidant activities including free radical scavenging against DPPH and ABTS radicals, FRAP, and ORAC. In particular, the wheat germ roasted at 180 °C for 20 min showed higher antioxidant activity than those roasted at 180 °C for 5 and 10 min. Three major phenolic acids, namely, ferulic, chlorogenic, and caffeic acid, and four main flavonoids, namely, schaftoside and its isomers or adduct of sinapic acid were identified by HPLC. In general, the content of individual phenolic compounds decreased with prolongation of the roasting time except for ferulic acid. The results suggest that the antioxidant activities of wheat germ can be enhanced by roasting, and the enhancement effect might be partially attributed to the formation of Maillard reaction products (MRP).

Published: July 2015

Background:Aboriginal and Torres Strait Islander Australians experience stroke and traumatic brain injury (TBI) with much greater frequency than non-Aboriginal Australians. Acquired communication disorders (ACD) can result from these conditions and can significantly impact everyday life. Yet few Aboriginal people access rehabilitation services and little is known about Aboriginal peoples’ experiences of ACD. This paper describes the protocol surrounding a study that aims to explore the extent and impact of ACD in Western Australian Aboriginal populations following stroke or TBI and develop a culturally appropriate screening tool for ACD and accessible and culturally appropriate service delivery models.Method/Design:The 3-year, mixed methods study is being conducted in metropolitan Perth and five regional centres in Western Australia. Situated within an Aboriginal research framework, methods include an analysis of linked routine hospital admission data and retrospective file audits, development of a screening tool for ACD, interviews with people with ACD, their families, and health professionals, and drafting of alternative service delivery models.Discussion:This study will address the extent of ACD in Aboriginal populations and document challenges for Aboriginal people in accessing speech pathology services. Documenting the burden and impact of ACD within a culturally secure framework is a forerunner to developing better ways to address the problems faced by Aboriginal people with ACD and their families. This will in turn increase the likelihood that Aboriginal people with ACD will be diagnosed and referred to professional support to improve their communication, quality of life and functioning within the family and community context.

Published: July 2015

AbstractObjectiveTo determine the effect of triage nurse initiated radiographs using the Ottawa Ankle Rules (OAR) on emergency department (ED) throughput. We hypothesized OAR use would reduce median ED length of stay (LOS) by 25 minutes or more.MethodsA randomized controlled trial was conducted at a tertiary centre ED with an annual census of over 90,000 patients. Adult patients presenting within 10 days of isolated blunt ankle trauma were eligible. Participants were randomly assigned to standard triage or OAR application by 15 explicitly trained triage nurses. Our primary outcome was ED LOS. Secondary outcomes included triage nurses' and patients’ satisfaction. A power calculation indicated 142 patients were required. The Mann-Whitney U test was used to compare the medians between the two groups.ResultsOf 176 patients with blunt ankle injury screened, 146 were enrolled (83.0%); baseline characteristics in the two groups were similar. The median/mean ED LOS in the control and OAR groups were 128/143 minutes and 108/115 minutes respectively (median difference 20 minutes; p=0.003). Agreement in OAR use between emergency physicians and nurses was moderate (kappa 0.46/0.77 for foot/ankle rule components), and satisfaction of both nurses and participants was high.ConclusionTriage nurse initiated radiography using OAR leads to a statistically significant decrease of 20 minutes in the median ED LOS at a tertiary care centre. The overall impact of implementing such a process is likely site-specific, and the decision to do so should involve consideration of the local context.
The Northern Ireland government and the welfare state, 1942–8: the case of health provision
Authors: Privilege John 
Published: July 2015

Abstract

Northern Ireland, the United Kingdom’s only self-governing region, recorded year-on- year the worst statistics on health and poverty. However, it was far from certain that the Unionist government in Belfast would enact the kind of sweeping post-war reform that occurred in England and Wales. The raft of legislation governing health and social care introduced in 1948 was, therefore, the product of conditions and circumstances peculiar to Northern Ireland. The government in Belfast needed to overcome the conservative instincts of Ulster Unionism as well as suspicions regarding Clement Attlee’s Labour administration. Although the process was somewhat blighted by sectarianism, the government of Sir Basil Brooke enacted what amounted to a revolution in health and social care provision.
‘Syphilis is given over to sentimentalists’: the Dublin Medical Press and Circular and the drive to extend the Contagious Diseases Acts
Authors: Daly Ann 
Published: July 2015

Abstract
In 1878, a meeting organised in Dublin by those in favour of repealing the contentious Contagious Diseases Acts ended in chaos and disruption. The acts themselves empowered police and doctors to forcibly detain and examine women (within specified geographical locations) suspected of being infected with venereal disease. The campaign to abolish the acts appeared to lack the widespread support that it had gathered in England, particularly in medical circles, and the disorderliness of the Dublin meeting seemed to confirm this. The Irish medical press, specifically the weekly Dublin Medical Press and Circular (D.M.P.C.) mirrored The Lancet’s vilification of those who sought to abolish the acts. This article examines the D.M.P.C.’s campaign to extend the acts in Ireland and explores its influence within the context of the debate surrounding these controversial acts. Despite prolific representation of leading English medics among those who opposed the acts, the D.M.P.C. did not offer any outspoken testimony for the repeal of the C.D.A.s by an important figure in the Irish medical profession. This article examines the reasons for such a muted response by Irish doctors to the draconian legislation that directly involved the profession.

SUMMARYTo support tropical maize (Zea maysL.) breeding efforts, the current work aimed to assess harvest index (HI) in modern hybrids and determine the effect of different planting densities on grain yield and HI under well-fertilized (HN) and nitrogen (N) deficient conditions. Harvest index and grain yield of 34 hybrids on average reached 0·42 and 7·06 t/ha (five environments), indicating a large potential for improvement in HI relative to temperate hybrids. Ear weight (r= 0·88), HI (r= 0·78) and shoot dry weight (r= 0·68) were strongly associated with grain yield. In the second experiment, seven hybrids were evaluated at planting densities of 5, 7, 9 and 11 plants/m2under HN (six environments) and N deficient (LN) conditions (four environments) to assess the effect of planting density on grain yield and HI. Grain yield increased by 40·4 and 21·8% under HN and LN conditions when planting density was increased relative to the lowest planting density. Harvest index increased from 0·42 at 5 plants/m2to 0·45 at 11 plants/m2under HN conditions and decreased from 0·44 at 5 plants/m2to 0·42 at 9 plants/m2under LN conditions. Harvest index was maximized at planting densities of 8·33 plants/m2and 5·30 plants/m2under HN and LN conditions, respectively, while grain yield was maximized at 9·93 plants/m2and 7·89/m2. Optimal planting density maximizing both HI and grain yield were higher than planting densities currently used in tropical germplasm. It can be concluded that productivity in tropical maize could be increased both under intensive (+40·4%) and lower-input management (+21·8%) by increasing planting densities above those currently used in smallholder agriculture in Latin America and Sub-Saharan Africa, in environments targeted by the International Maize and Wheat Improvement Center.
Rule-of-law Lineages in Colonial and Early Post-colonial Burma
Authors: CHEESMAN NICK 
Published: July 2015

AbstractThese days the rule of law is often invoked in Burma. Although its contemporary salience is partly a consequence of recent global trends, the rule of law also has lineages in the country's colonial and early post-colonial periods. To examine these lineages, this article distinguishes between its procedural and substantive conceptions. Whereas the latter conception recognizes the subjects of law as freely associating equals, the former is compatible with a range of political practices, including those that are undemocratic. The records of decisions in criminal cases before Burma's superior courts during the period of British domination suggest that some semblance of procedural rule of law did exist, and that it was compatible with the rule of colonial difference. Out of this procedural rule of law a nascent, substantive type emerged during the early years of democratic life in the post-colony, before the onset of military dictatorship. The article concludes that more effort to structure interpretations of the rule of law in history might better enable discussion about the concept's continued relevance.

BackgroundCivilian suicide rates vary by occupation in ways related to occupational stress exposure. Comparable military research finds suicide rates elevated in combat arms occupations. However, no research has evaluated variation in this pattern by deployment history, the indicator of occupation stress widely considered responsible for the recent rise in the military suicide rate.MethodThe joint associations of Army occupation and deployment history in predicting suicides were analysed in an administrative dataset for the 729 337 male enlisted Regular Army soldiers in the US Army between 2004 and 2009.ResultsThere were 496 suicides over the study period (22.4/100 000 person-years). Only two occupational categories, both in combat arms, had significantly elevated suicide rates: infantrymen (37.2/100 000 person-years) and combat engineers (38.2/100 000 person-years). However, the suicide rates in these two categories were significantly lower when currently deployed (30.6/100 000 person-years) than never deployed or previously deployed (41.2–39.1/100 000 person-years), whereas the suicide rate of other soldiers was significantly higher when currently deployed and previously deployed (20.2–22.4/100 000 person-years) than never deployed (14.5/100 000 person-years), resulting in the adjusted suicide rate of infantrymen and combat engineers being most elevated when never deployed [odds ratio (OR) 2.9, 95% confidence interval (CI) 2.1–4.1], less so when previously deployed (OR 1.6, 95% CI 1.1–2.1), and not at all when currently deployed (OR 1.2, 95% CI 0.8–1.8). Adjustment for a differential ‘healthy warrior effect’ cannot explain this variation in the relative suicide rates of never-deployed infantrymen and combat engineers by deployment status.ConclusionsEfforts are needed to elucidate the causal mechanisms underlying this interaction to guide preventive interventions for soldiers at high suicide risk.
Cross-linguistic interactions from second language to first language as the result of individualized narrative language intervention with children with and without language impairment
Authors: PETERSEN DOUGLAS B. , THOMPSEN BRENNA , GUIBERSON MARK M. , SPENCER TRINA D. 
Published: July 2015

ABSTRACTThis study investigated the extent to which results of English narrative intervention interacted cross-linguistically with Spanish for 73 bilingual children. We employed a quasi-experimental design, using matched-pairs random assignment for children with typically developing language and a nonrandom block design for children with language impairment. At pretest and posttest we elicited three different English and Spanish narrative retells. We conducted two 25-min, individualized narrative intervention sessions in English with the treatment group, focusing on causal subordination and story grammar. The results indicated that the English narrative intervention was efficacious for both causal subordination and story grammar. They also indicated that the typically developing children had significantly greater cross-linguistic transfer of causal subordination and story grammar than did the children with language impairment.
Uncertainty estimation in robust tracking control of robot manipulators using the Fourier series expansion
Authors: Khorashadizadeh Saeed , Fateh Mohammad Mehdi 
Published: July 2015

SUMMARYThis paper presents a novel control algorithm for electrically driven robot manipulators. The proposed control law is simple and model-free based on the voltage control strategy with the decentralized structure and only joint position feedback. It works for both repetitive and non-repetitive tasks. Recently, some control approaches based on the uncertainty estimation using the Fourier series have been presented. However, the proper value for the fundamental period duration has been left as an open problem. This paper addresses this issue and intuitively shows that in order to perform repetitive tasks; the least common multiple (LCM) of fundamental period durations of the desired trajectories of the joints is a proper value for the fundamental period duration of the Fourier series expansion. Selecting the LCM results in the least tracking error. Moreover, the truncation error is compensated by the proposed control law to make the tracking error as small as possible. Adaptation laws for determining the Fourier series coefficients are derived according to the stability analysis. The case study is an SCARA robot manipulator driven by permanent magnet DC motors. Simulation results and comparisons with a voltage-based controller using adaptive neuro-fuzzy systems show the effectiveness of the proposed control approach in tracking various periodic trajectories. Moreover, the experimental results on a real SCARA robot manipulator verify the successful practical implementation of the proposed controller.
VALUE NEUTRALITY AND THE RANKING OF OPPORTUNITY SETS
Authors: Garnett Michael 
Published: July 2015

Abstract:I argue that a liberal commitment to value neutrality is best honoured by maintaining a pure cardinality component in our rankings of opportunity sets. Two challenges to this claim are considered. The first holds that cardinality rankings areunnecessaryfor neutrality, since what matters from this perspective is thevariety(and not the meresize) of opportunity sets. The second holds that pure cardinality metrics areinsufficientfor neutrality, because opportunities cannot be individuated into countable entities without presupposing some relevantly partisan evaluative perspective. In each case, a clear understanding of the liberal basis for valuing liberty yields a satisfying response.

Published: July 2015

ObjectiveSignificant differences in clinical profile and comorbidity patterns have been observed between “juvenile-onset” and “adult-onset” obsessive-compulsive disorder (OCD). There is little systematic research on onset of OCD after the fourth decade. The current study aims to compare the demographic, clinical, and comorbidity patterns of patients with “juvenile-onset” (<18 years), “adult-onset” (18–39 years), and “late-onset” (≥40 years) OCD.MethodEight hundred two consecutive patients who consulted a specialty OCD clinic at a tertiary care hospital in India were evaluated with the Mini International Neuropsychiatric Interview, the Yale–Brown Obsessive-Compulsive Scale, and the Clinical Global Impression scale.Results37.4%, 57.4%, and 5.2% of patients had juvenile-, adult-, and late-onset OCD, respectively. Late-onset OCD was associated with female gender (χ2=42, p<0.001); negative family history of OCD in first-degree relatives (χ2=20.4, p<0.001); and less aggressive obsessions (χ2=18.16, p<0.001), sexual obsessions (χ2=26.68, p<0.001), pathological doubts (χ2=19.41; p<0.001), and repeating rituals (χ2=44.28; p<0.001). On multinomial logistic regression, late-onset OCD was significantly associated with female gender, collecting compulsions, and less aggressive obsessions, in comparison with adult-onset OCD. In comparison with juvenile-onset, late-onset OCD was significantly associated with female gender, presence of precipitating factors, and less aggressive obsessions, sexual obsessions, and repeating compulsions.ConclusionLate-onset OCD is characterized by female gender, lesser familial loading for OCD, and presence of precipitating factors, suggesting that it may have a distinct pathophysiology compared to juvenile- and adult-onset OCD. Systematic research is required to understand the family-genetic, neuropsychological, and neurobiological correlates of late-onset OCD.
