Approach to Define a Non Functional Requirements Elicitation Guide Using a Customer Language
Venue: SEKE

Non functional requirements (NFR) have a crucial role in the software development process because they correspond to the characteristics and restrictions on which the s oftware must running and represent factors that influence the ti me and cost of software development. Nevertheless, many organizations do not perform these requirements elicitation properly. This paper presents an approach to creating a NFR elicitation guide focused on customer language. To create the approach was performed a systematic review which identified and analyzed rel ated works. Also a survey was conducted which helped to know the current situation of NFR elicitation in software development organizations and obtained suggestions for composition of the NFR elicitation guide. Finally, the results of appl ying the proposed approach presents evidence that the use of the process is feasible and produces better quality requirement s.
Robust sound source mapping using three layered selective audio rays for mobile robots
Venue: 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

This paper investigates sound source mapping in a real environment using a mobile robot. Our approach is based on audio ray tracing which integrates occupancy grids and sound source localization using a laser range finder and a microphone array. Previous audio ray tracing approaches rely on all observed rays and grids. As such observation errors caused by sound reflection, sound occlusion, wall occlusion, sounds at misdetected grids, etc. can significantly degrade the ability to locate sound sources in a map. A three layered selective audio ray tracing mechanism is proposed in this work. The first layer conducts frame based unreliable ray rejection (sensory rejection) considering sound reflection and wall occlusion. The second layer introduces triangulation and audio tracing to detect falsely detected sound sources, rejecting audio rays associated to these misdetected sounds sources (short term rejection) A third layer is tasked with rejecting rays using the whole history (long term rejection) to disambiguate sound occlusion. Experimental results under various situations are presented, which proves the effectiveness of our method.
The effect of pomegranate juice (no added sugar) consumption on fast blood sugar, lipid profile, antioxidant factors in Type 2 diabetes

Diabetes mellitus is one of the prevalence metabolic disorders in the worldwide. Studies have shown that fruits, vegetables and drinks that are rich in phenolic and antioxidants components may reduce cardiovascular and diabetes diseases. One of these fruits is Pomegranate that is rich in phelavonoid. Therefore, this study was designed to determine pomegranate juice effect on fast blood sugar, lipid profile, anthropometry, total antioxidant capacity and blood pressure in diabetic patients.  In the present study, 50 patients with diabetes aged 30 50 were recruited into the study and randomly assigned into 2 groups:1) intervention group (n=25) that fed 240cc pomegranate juice daily, 2) control group (n=25) that fed 240cc water daily. Weight, hip circumstance, waist circumstance, lipid profile (HDL C, LDL C, TG, TC) glucose, HbA1C, GPX, total antioxidant capacity, systolic and diastolic blood pressure were measured at the baseline and end of 8 weeks.  Insulin resistance, systolic and diastolic blood pressure, body weight, hip circumstance, waist circumstance decreased significantly and GPX increased in intervention group whereas pomegranate juice had no significant effect on glucose, HbA1C, lipid profile and total antioxidant capacity.  These findings indicate that beneficial effect of pomegranate juice on insulin resistance, systolic and diastolic blood pressure, body weight, hip circumstance, waist circumstance, GPX.

Translational failure of anti inflammatory compounds for myocardial infarction: a meta analysis of large animal models.
Venue: Cardiovascular research

Numerous anti inflammatory drugs have been tested in large animal studies of myocardial infarction (MI) Despite positive results, translation of anti inflammatory strategies into clinical practice has proved to be difficult. Critical disparities between preclinical and clinical study design that influence efficacy may partly be responsible for this translational failure. The aim of the present systematic review was to better understand which factors underlie the failure of transition towards the clinic.  Meta analysis and regression of large animal studies were performed to identify sources that influenced effect size of anti inflammatory compounds in large animal models of MI. We included 183 studies, containing 3331 large animals. Infarct size (IS) as a ratio of the area at risk (12.7% 95% confidence interval, CI 11.1 14.4% P 0.001) and IS as a ratio of the left ventricle (3.9% 95% CI 3.1 4.7% P 0.001) were reduced in treatment compared with control groups. Effect size was higher when outcome was assessed early after MI (P 0.013) and where studies included only male animals (P 0.001) Mortality in treated animals was higher in studies that blinded the investigator during the experiment (P 0.041) and depended on the type of drug used (P 0.001)  As expected, treatment with anti inflammatory drugs leads to smaller infarct size in large animal MI models. Timing of outcome assessment, sex, and study quality are significantly associated with outcome and may explain part of the translational failure in clinical settings. Effect size depends on the type of drug used, enabling identification of compounds for future clinical testing.
Dynamics of H2 adsorbed in porous materials as revealed by computational analysis of inelastic neutron scattering spectra.
Venue: Physical chemistry chemical physics PCCP

The inelastic scattering of neutrons from adsorbed H2 is an effective and highly sensitive method for obtaining molecular level information on the type and nature of H2 binding sites in porous materials. While these inelastic neutron scattering (INS) spectra of the hindered rotational and translational excitations on the adsorbed H2 contain a significant amount of information, much of this can only be reliably extracted by means of a detailed analysis of the spectra through the utilization of models and theoretical calculations. For instance, the rotational tunneling transitions observed in the INS spectra can be related to a value for the barrier to rotation for the adsorbed H2 with the use of a simple phenomenological model. Since such an analysis is dependent on the model, it is far more desirable to use theoretical methods to compute a potential energy surface (PES) from which the rotational barriers for H2 adsorbed at a particular site can be determined. Rotational energy levels and transitions for the hindered rotor can be obtained by quantum dynamics calculations and compared directly with experiment with an accuracy subject only to the quality of the theoretical PES. In this paper, we review some of the quantum and classical mechanical calculations that have been performed on H2 adsorbed in various porous materials, such as clathrate hydrates, zeolites, and metal organic frameworks (MOFs) The principal aims of these calculations have been the interpretation of the INS spectra for adsorbed H2 along with the extraction of atomic level details of its interaction with the host. We describe calculations of the PES used for two dimensional quantum rotation as well as rigorous five dimensional quantum coupled translation rotation dynamics, and demonstrate that the combination of INS measurements and computational modeling can provide important and detailed insights into the molecular mechanism of H2 adsorption in porous materials.
Unpacking the impacts of the Low Income Housing Tax Credit program on nearby property values

Most existing research on the impacts of the Low Income Housing Tax Credit (LIHTC) on neighbouring property values is limited in terms of providing causal attribution and uncovering nuances in the role of housing market and neighbourhood composition. This article addresses these shortcomings by investigating the impacts of the LIHTC program in Charlotte, North Carolina and Cleveland, Ohio. Levels and trends in housing prices before and after LIHTC developments in neighbourhoods are examined based on parcel level housing sales data from 1996 to 2007. The Adjusted Interrupted Time Series Difference in Differences (AITS DID) model is used to clarify the causal direction of impacts of LIHTC developments. The results show that LIHTC developments have negative impacts in Charlotte, while having upgrading effects in Cleveland. Also, these impacts vary across neighbourhoods' income heterogeneity. Thus, care should be taken when siting LIHTC developments to minimise negative impacts and enhance its use for community revitalisation across different housing market conditions.
Poverty concentration and the Low Income Housing Tax Credit: Effects of siting and tenant composition

New evidence on the effects of growing up in neighborhoods of concentrated poverty has heightened policy interest in understanding the role housing programs may play in shaping the distribution of poverty. In particular, as the nation's largest source of funding for the construction of affordable rental housing, the Low Income Housing Tax Credit (LIHTC) could play a critical role in shaping the distribution of poverty. This paper examines whether the LIHTC affects the concentration of poverty by examining who lives in tax credit developments in different neighborhoods, and how neighborhoods and metropolitan areas change after LIHTC developments are built. Through assessing both the effects of siting and tenant composition, we find little evidence that the LIHTC is increasing the concentration of poverty and we find some evidence that it is reducing poverty rates in high poverty neighborhoods. We also make suggestions for states who want to use LIHTC to do more to deconcentrate poverty.
Impacts of the Low Income Housing Tax Credit Program on Neighborhood Housing Turnover

Although the Low Income Housing Tax Credit (LIHTC) program has grown into the largest subsidized housing program in the United States, we have limited understanding of how these units affect the neighborhoods in which they are located. This article examines impacts of the LIHTC program on neighborhood stability in the cities of Charlotte and Cleveland. We examine housing turnover before and after the introduction of LIHTC developments into the neighborhood, based on housing sales data from 1996 to 2007. Location data on LIHTC units are merged with parcel level sales data from Mecklenburg and Cuyahoga Counties. We estimate an extended Cox hazard model with the difference in difference specification to determine whether LIHTC units are causing increased turnover of neighborhood housing. We also explore impacts on neighborhood stability from LIHTC developments citywide and in neighborhoods stratified by income. We find significant impacts on the stability of LIHTC developments in both cities. Particularly, in higher income submarkets, strong spillover effects were observed in Charlotte. Our results suggest that the stability of neighborhoods may be an important factor when considering the siting of LIHTC developments.
Housing tax reform: Is there a way forward?

Australian home owners and investors benefit from various tax concessions. Home owner tax concessions are poorly targeted with older, higher income households the main beneficiaries. There could also be efficiency consequences if the tax favoured owner occupied housing sector attracts investment that would otherwise have been employed more productively elsewhere. Investors can use negative gearing to convert ordinary income into capital gains that are taxed leniently. These tax benefits distort the supply of rental housing to the detriment of affordable rental housing opportunities. To address some of these concerns, the paper examines a potential tax reform package that would replace stamp duty by a uniform flat rate land tax. Using Victorian Valuer General property data, we estimate the land tax liabilities that property owners would be asked to pay if a revenue neutral broad based land tax replaced stamp duty on conveyance. We describe these land tax burdens if hypothetically levied in Melbourne as of 2005 2006, and compare the new tax burdens with liabilities under existing stamp duty provisions. The strong efficiency case in favour of such a tax substitution is complemented by empirical findings which suggest that higher income communities shoulder higher land tax burdens.
Microglia in the TBI brain: The good, the bad, and the dysregulated
Venue: Experimental Neurology

As the major cellular component of the innate immune system in the central nervous system (CNS) and the first line of defense whenever injury or disease occurs, microglia play a critical role in neuroinflammation following a traumatic brain injury (TBI) In the injured brain microglia can produce neuroprotective factors, clear cellular debris and orchestrate neurorestorative processes that are beneficial for neurological recovery after TBI. However, microglia can also become dysregulated and can produce high levels of pro inflammatory and cytotoxic mediators that hinder CNS repair and contribute to neuronal dysfunction and cell death. The dual role of microglial activation in promoting beneficial and detrimental effects on neurons may be accounted for by their polarization state and functional responses after injury. In this review article we discuss emerging research on microglial activation phenotypes in the context of acute brain injury, and the potential role of microglia in phenotype specific neurorestorative processes such as neurogenesis, angiogenesis, oligodendrogenesis and regeneration. We also describe some of the known molecular mechanisms that regulate phenotype switching, and highlight new therapeutic approaches that alter microglial activation state balance to enhance long term functional recovery after TBI. An improved understanding of the regulatory mechanisms that control microglial phenotypic shifts may advance our knowledge of post injury recovery and repair, and provide opportunities for the development of novel therapeutic strategies for TBI.
Erythropoietin in traumatic brain injury (EPO TBI) a double blind randomised controlled trial
Venue: The Lancet

Erythropoietin might have neurocytoprotective effects. In this trial, we studied its effect on neurological recovery, mortality, and venous thrombotic events in patients with traumatic brain injury.  Erythropoietin in Traumatic Brain Injury (EPO TBI) was a double blind, placebo controlled trial undertaken in 29 centres (all university affiliated teaching hospitals) in seven countries (Australia, New Zealand, France, Germany, Finland, Ireland, and Saudi Arabia) Within 24 h of brain injury, 606 patients were randomly assigned by a concealed web based computer generated randomisation schedule to erythropoietin (40,000 units subcutaneously) or placebo (0*9% sodium chloride subcutaneously) once per week for a maximum of three doses. Randomisation was stratified by severity of traumatic brain injury (moderate vs severe) and participating site. With the exception of designated site pharmacists, the site dosing nurses at all sites, and the pharmacists at the central pharmacy in France, all study personnel, patients, and patients' relatives were masked to treatment assignment. The primary outcome, assessed at 6 months by modified intention to treat analysis, was improvement in the patients' neurological status, summarised as a reduction in the proportion of patients with an Extended Glasgow Outcome Scale (GOS E) of 1 4 (death, vegetative state, and severe disability) Two equally spaced preplanned interim analyses were done (after 202 and 404 participants were enrolled) This study is registered with ClinicalTrials.gov, number NCT00987454.  Between May 3, 2010, and Nov 1, 2014, 606 patients were enrolled and randomly assigned to erythropoietin (n=308) or placebo (n=298) Ten of these patients (six in the erythropoietin group and four in the placebo group) were lost to follow up at 6 months; therefore, data for the primary outcome analysis was available for 596 patients (302 in the erythropoietin group and 294 in the placebo group) Compared with placebo, erythropoietin did not reduce the proportion of patients with a GOS E level of 1 4 (134 [44% of 302 patients in the erythropoietin group vs 132 [45% of 294 in the placebo group; relative risk [RR] 0*99 [95% CI 0*83 1*18] p=0*90) In terms of safety, erythropoietin did not significantly affect 6 month mortality versus placebo (32 [11% of 305 patients had died at 6 months in the erythropoietin group vs 46 [16% of 297 [16% in the placebo group; RR 0*68 [95% CI 0*44 1*03] p=0*07) or increase the occurrence of deep venous thrombosis of the lower limbs (48 [16% of 305 vs 54 [18% of 298; RR 0*87 [95% CI 0*61 1*24] p=0*44) INTERPRETATION Following moderate or severe traumatic brain injury, erythropoietin did not reduce the number of patients with severe neurological dysfunction (GOS E level 1 4) or increase the incidence of deep venous thrombosis of the lower limbs. The effect of erythropoietin on mortality remains uncertain.
White matter involvement after TBI: Clues to axon and myelin repair capacity
Venue: Experimental Neurology

Impact acceleration forces to the head cause traumatic brain injury (TBI) with damage in white matter tracts comprised of long axons traversing the brain. White matter injury after TBI involves both traumatic axonal injury (TAI) and myelin pathology that evolves throughout the post injury time course. The axon response to initial mechanical forces and secondary insults follows the process of Wallerian degeneration, which initiates as a potentially reversible phase of intra axonal damage and proceeds to an irreversible phase of axon fragmentation. Distal to sites of axon disconnection, myelin sheaths remain for prolonged periods, which may activate neuroinflammation and inhibit axon regeneration. In addition to TAI, TBI can cause demyelination of intact axons. These evolving features of axon and myelin pathology also represent opportunities for repair. In experimental TBI, demyelinated axons exhibit remyelination, which can serve to both protect axons and facilitate recovery of function. Myelin remodeling may also contribute to neuroplasticity. Efficient clearance of myelin debris is a potential target to attenuate the progression of chronic pathology. During the early phase of Wallerian degeneration, interventions that prevent the transition from reversible damage to axon disconnection warrant the highest priority, based on the poor regenerative capacity of axons in the CNS. Clinical evaluation of TBI will need to address the challenge of accurately detecting the extent and stage of axon damage. Distinguishing the complex white matter changes associated with axons and myelin is necessary for interpreting advanced neuroimaging approaches and for identifying a broader range of therapeutic opportunities to improve outcome after TBI.
A multi objective model for locating search and rescue boats
Venue: Eur. J. Oper. Res.

We present the Incident Based Boat Allocation Model (IB BAM) a multi objective model designed to allocate search and rescue resources. The decision of where to locate search and rescue boats depends upon a set of criteria that are unique to a given problem such as the density and types of incidents responded in the area of interest, resource capabilities, geographical factors and governments' business rules. Thus, traditional models that incorporate only political decisions are no longer appropriate. IB BAM considers all these criteria and determines optimal boat allocation plans with the objectives of minimizing response time to incidents, fleet operating cost and the mismatch between boats' workload and operation capacity hours.

What Do a Bank's Legal Expenses Reveal About its Internal Controls and Operational Risk?

Excessive (substantially above peer) litigation against a bank is indicative of operational risk because it often suggests failure to maintain a strong system of internal control. We examine the relation between bank performance and weak internal control using legal expense as a proxy. We find that legal expense is a strong determinant of loan losses and stock returns. Bank regulators should require reporting of legal expense on call reports to help identify institutions with weaknesses in internal control. Current reporting creates unnecessary information asymmetries because investors are not well informed about operational risk, leading to mispricing of bank securities.
Pleine conscience et management effet de la mindfulness sur la relation au travail et le style de leadership des managers.

La pleine conscience (mindfulness) est un concept plurimillenaire fondamental dans les traditions meditatives. C'est aujourd'hui un construit psychologique faisant l'objet d'une litterature importante et une technique therapeutique eprouvee, notamment dans la reduction du stress et la prevention de la rechute depressive (Bishop et al. 2004 Brown, Ryan et Creswell, 2007 Grossman et al. 2004) La mindfulness et ses effets sur les pratiques de management font l'objet d'un nombre de recherches limite (Dane, 2010 Good et al. 2016) La these que nous defendons est que la mindfulness est un construit psychologique qui est doublement benefique aux managers d'une part en soutenant un rapport plus equilibre au travail, d'autre part en favorisant l'adoption de comportements de leadership plus positifs et performants (leadership transformationnel, authentique ou servant) Notre recherche mobilise une methode mixte. Une revue systematique de litterature permet de baliser ce champ emergent. Une quasi experimentation sur 7 managers d'une entreprise industrielle, menee pendant 2 ans selon un protocole qualitatif longitudinal, rend compte des evolutions observees en termes de rapport au travail et de style de management. Enfin, un modele utilisant les formes positives de leadership comme mediateurs de la relation mindfulness performance est propose. Deux etudes quantitatives sont menees pour tester le modele. Les donnees defendent la these selon laquelle la mindfulness est une ressource mobilisable pour induire des comportements organisationnels positifs.
