Status of the Elderly and Emergence of Old Age Homes in India
Authors: Menezes Sunita , Thomas Tissy Mariam 
Published: January 2018

There has been a rapid ageing of the earth's population and in a few decades, Asia could become the oldest region in the world. In India, due to the reorganization of the family system, the traditional joint family system is on the decline. Due to the emergence of the nuclear family and the high cost of living, family members who previously cared for the elderly need to find employment outside the home. A rapid increase in nuclear families and an exceptional increase in the number of ‘older adults’ in the country have compelled them to live in old age homes. Literature has accentuated the difficulties and apprehensions experienced by older adults during the ageing process and the need for old age homes in order to create an environment that fosters a meaningful existence for them in their twilight years. India's old age homes are trying to uphold the needs, desires and values of older adults. There is a lack of studies that attempt to give older adults a chance to communicate their experiences in a care home. Older adults are an invaluable resource for younger generations and change is needed in society's attitude towards ageing. This review can help psychologists, social workers and caregivers gain insight into the needs of older adults in terms of mental wellbeing, economic and social security and elder abuse and create awareness among the people.

Authors: Al-Marshoudi Ahmed Salim 
Published: January 2018

Oman, which is located on the Southern East of Arabian Peninsula, classified as holding a semi-arid climate with an average annual rainfall of 100 mm. Therefore, agricultural production in Oman is fully dependent in irrigation. More than one third is supplied by the ancient aflaj (sing. Falaj), which provide 680 x 106 m3 of water per year and irrigate of an area of 26,500 ha. There is two commonly known definition of the aflaj; the locally defined from the classic Arabic root as to divide the water among its shareholders. In addition, the modern technical definition as trenches and tunnels, which are dug in the ground, to convey the accumulated rainfall water table to the irrigated area in the villages. This study explore some of the existing institutional arrangements found within Falajdaris, at the waliyat (city) of Nizwalocated in the Dakhillya governmental, Sultanate of Oman. This study uses mainly face-To-face interviews with local administrative falaj agents to explore and discuss the most operated mechanized of the institutional arrangements. The study concluded that there is strong relationship between FalajDaris institutional arrangements development and physical water variability. Int. J. Soc. Sc. Manage. Vol. 5, Issue-1: 31-42
Medium-Term Outcome and CT Assessment of Lateral Foraminotomy at the Lumbosacral Junction in Dogs with Degenerative Lumbosacral Stenosis
Authors: Hartman Angela , Bridges Janis , Jones Boyd , Mayhew Joe , Worth Andrew 
Published: January 2018

Objective This article aims to report the medium-term clinical outcome and assess persistence of enlargement of the lumbosacral lateral intervertebral neurovascular foramen using computed tomography (CT) volumetric analysis in dogs following lateral foraminotomy.
Materials Six dogs that underwent lumbosacral lateral foraminotomy on one or both sides were evaluated with CT prior to, immediately postoperatively (n = 2) and at 12 to 44 months of follow-up. Five out of six dogs had successful clinical outcomes with alleviation of pain and increased levels of activity, according to subjective assessment. Immediate postoperative CT volumetric analysis of the lateral intervertebral neurovascular foramina in two dogs indicated a 650 to 800% increase in volume in extension achieved by foraminotomy (four foramens). At subsequent follow-up, bone regrowth had occurred with reduction in foraminal volume, though in both dogs foraminal volume remained higher than preoperative values. Follow-up CT at a median of 24 months postoperatively indicated a mean 335% increase in volume of the lumbosacral lateral intervertebral neurovascular foramina in extension compared with the preoperative foraminal volume. The follow-up volume was substantially greater than the presurgical volume in four out of six dogs.
Clinical Significance In this limited case series, lateral foraminotomy achieved persistent enlargement of the lumbosacral lateral intervertebral neurovascular foramen in the medium term, but osseous regrowth at the site was demonstrated which may limit the effectiveness of lateral foraminotomy in the longer term. One of two working dogs had recurrent clinical signs that necessitated further surgery.

Abstract
New results on the short-term galactic cosmic-ray (GCR) intensity variation (Forbish decrease) in 2006 December measured by the PAMELA instrument are presented. Forbush decreases are sudden suppressions of the GCR intensities, which are associated with the passage of interplanetary transients such as shocks and interplanetary coronal mass ejections (ICMEs). Most of the past measurements of this phenomenon were carried out with ground-based detectors such as neutron monitors or muon telescopes. These techniques allow only the indirect detection of the overall GCR intensity over an integrated energy range. For the first time, thanks to the unique features of the PAMELA magnetic spectrometer, the Forbush decrease, commencing on 2006 December 14 and following a CME at the Sun on 2006 December 13, was studied in a wide rigidity range (0.4–20 GV) and for different species of GCRs detected directly in space. The daily averaged GCR proton intensity was used to investigate the rigidity dependence of the amplitude and the recovery time of the Forbush decrease. Additionally, for the first time, the temporal variations in the helium and electron intensities during a Forbush decrease were studied. Interestingly, the temporal evolutions of the helium and proton intensities during the Forbush decrease were found to be in good agreement, while the low rigidity electrons (

GV) displayed a faster recovery. This difference in the electron recovery is interpreted as a charge sign dependence introduced by drift motions experienced by the GCRs during their propagation through the heliosphere.

Abstract
We apply the algorithm published by Liang et al. to describe the Double Pulsar system J0737–3039 and extract the sense of rotation of the first born recycled pulsar PSR J0737–3039A. We find that this pulsar is rotating prograde in its orbit. This is the first direct measurement of the sense of rotation of a pulsar with respect to its orbit and a direct confirmation of the rotating lighthouse model for pulsars. This result confirms that the spin angular momentum vector is closely aligned with the orbital angular momentum, suggesting that the kick of the supernova producing the second born pulsar J0737–3039B was small.
Multi-epoch VLBA Imaging of 20 New TeV Blazars: Apparent Jet Speeds
Authors: Piner B. Glenn , Edwards Philip G. 
Published: January 2018

Abstract
We present 88 multi-epoch Very Long Baseline Array (VLBA) images (most at an observing frequency of 8 GHz) of 20 TeV blazars, all of the high-frequency-peaked BL Lac (HBL) class, that have not been previously studied at multiple epochs on the parsec scale. From these 20 sources, we analyze the apparent speeds of 43 jet components that are all detected at four or more epochs. As has been found for other TeV HBLs, the apparent speeds of these components are relatively slow. About two-thirds of the components have an apparent speed that is consistent (within 2σ) with no motion, and some of these components may be stationary patterns whose apparent speed does not relate to the underlying bulk flow speed. In addition, a superluminal tail to the apparent speed distribution of the TeV HBLs is detected for the first time, with eight components in seven sources having a 2σ lower limit on the apparent speed exceeding

. We combine the data from these 20 sources with an additional 18 sources from the literature to analyze the complete apparent speed distribution of all 38 TeV HBLs that have been studied with very long baseline interferometry at multiple epochs. The highest 2σ apparent speed lower limit considering all sources is

. This suggests that bulk Lorentz factors of up to about 4, but probably not much higher, exist in the parsec-scale radio-emitting regions of these sources, consistent with estimates obtained in the radio by other means such as brightness temperatures. This can be reconciled with the high Lorentz factors estimated from the high-energy data if the jet has velocity structures consisting of different emission regions with different Lorentz factors. In particular, we analyze the current apparent speed data for the TeV HBLs in the context of a model with a fast central spine and a slower outer layer.
L’aménagement du territoire et la question de la différence culturelle au Canada. De l’invisibilité à la visibilisation des peuples autochtones
Authors: Hirt Irène , Desbiens Caroline 
Published: January 2018

Au Canada, l’aménagement a contribué à la dépossession des sociétés autochtones par la création des « réserves » amérindiennes et autres modes de gestion du territoire et des ressources. Cet article propose une approche critique du concept d’aménagement en le considérant comme un dispositif central de contrôle social dans le cadre de l’entreprise coloniale européenne. Il suggère que ces fondements coloniaux de l’aménagement sont actuellement remis en cause au Canada par la mise en œuvre de modèles de gestion partagée du territoire entre Autochtones et non Autochtones. Il démontre toutefois le caractère inégal de ces transformations sociales, en comparant deux situations contrastées au Québec : celle des Cris de l’Est de la Baie James, bénéficiant depuis les années 1970 d’importantes prérogatives en matière d’aménagement sur leurs territoires ancestraux grâce à la signature d’un traité moderne ; et celle d’une partie des Innus, qui, dans l’attente de la ratification d’un tel traité, doivent composer avec les décisions prises par la société majoritaire, relatives à la gestion du territoire et des ressources hors réserve.
Trajectoires d’intégration des villes françaises dans les réseaux économiques et financiers des firmes transnationales étrangères
Authors: Finance Olivier 
Published: January 2018

À l’échelle mondiale, les firmes transnationales sont à l’origine d’inégalités d’intégration substantielles. Il est bien connu qu’elles dirigent notamment leurs investissements avant tout depuis et à destination des pays du Nord. Peu observées à l’échelle des systèmes de villes, leurs stratégies de localisation placent pourtant les villes dans des positions très diverses : certaines se situent en tête de leurs réseaux, certaines se trouvent très intégrées en accueillant de nombreux investissements, d’autres encore en sont quasiment exclues. Nous observons l’inégale intégration des territoires aux réseaux des firmes étrangères en France, à une échelle plus fine que celle permise par la seule considération des statistiques conventionnelles, et ceci dans une perspective dynamique. Alors que les métropoles sont concernées en tout premier lieu par une mondialisation incluante, les villes plus petites sont engagées dans des trajectoires d’intégration très diverses : marginalité, rattrapage, renforcement et déclin. Ceci a pu être révélé par la décomposition des réseaux de filiation des firmes transnationales via une base inédite des établissements sous contrôle étranger dans les aires urbaines françaises et leur comparaison à un recensement des établissements nouvellement créés depuis 2003.
Occupational Therapy in Medicaid Home and Community-Based Services Waivers
Authors: Friedman Carli , VanPuymbrouck Laura 
Published: January 2018

Abstract
OBJECTIVE. Medicaid Home and Community-Based Services (HCBS) 1915(c) waivers are the largest provider of long-term services and supports for people with intellectual and developmental disabilities (IDDs). In this study, we explored how HCBS IDD waivers projected providing occupational therapy services in Fiscal Year (FY) 2015.
METHOD. Medicaid HCBS IDD waivers across the nation gathered from the Centers for Medicare and Medicaid Services were qualitatively and quantitatively analyzed to determine how they projected providing occupational therapy services in terms of service expenditures and utilization.
RESULTS. In FY 2015, $14.13 million of spending was projected for occupational therapy services of 7,500 participants. However, there was large heterogeneity across states and services in terms of total projected spending, spending per participant, and reimbursement rates.
CONCLUSION. Comparisons across states strengthen the profession’s ability to assert the value of its services. These findings can help identify best practices and can advocate for the refinement of state occupational therapy programs.
Eocene to Miocene Out‐of‐Sequence Deformation in the Eastern Tibetan Plateau: Insights From Shortening Structures in the Sichuan Basin

Published: January 2018

AbstractA distinctive NNE trending belt of shortening structures dominates the topography and deformation of the eastern Sichuan Basin, ~300 km east of the Tibetan Plateau. Debate continues as to whether the structures resulted from Cenozoic eastward growth of the Tibetan Plateau. A low‐temperature thermochronology (AFT and AHe) data set from four deep boreholes and adjacent outcrops intersecting a branch of the shortening structures indicates distinctive differential cooling at ~35–28 Ma across the structure, where stratigraphy has been offset vertically by ~0.8–1.3 km. This result forms the first quantitative evidence for the existence of a late Eocene‐Oligocene phase of shortening in the eastern Sichuan Basin, synchronous with the early phase of eastward growth and extrusion of the Tibetan Plateau. Further, a compilation of regional Cenozoic structures reveals a Miocene retreat of deformation from the foreland basin to the hinterland areas. Such a tectonic reorganization indicates that Eocene to Miocene deformation in the eastern Tibetan Plateau is out‐of‐sequence and was probably triggered by enhanced erosion in the eastern Tibetan Plateau.
Elasticity of Corundum at High Pressures and Temperatures: Implications for Pyrope Decomposition and Al‐Content Effect on Elastic Properties of Bridgmanite
Authors: Wang Wenzhong , Wu Zhongqing 
Published: January 2018

AbstractThe thermodynamic and elastic properties of corundum at high pressures and temperatures are calculated based on density functional theory within the local density approximation. The calculated results agree well with the available experimental results and provide reliable data up to 80 GPa and 2,500 K. Our results confirm that C14 should be positive at ambient conditions. Elastic moduli of corundum, especially its shear modulus, exhibit noticeable nonlinear dependences with pressure and thereby result in the nonlinear pressure dependences of wave velocities. The decomposition of pyrope into the assemblage of bridgmanite and corundum is also investigated within the generalized gradient approximation. The calculated phase boundary is comparable to experimental results and has a positive Clapeyron slope of +2.1 MPa/K. Pyrope decomposition can result in VP, VS, and density jumps of 12.4%, 20%, and 9.8%, respectively. A small amount of pyrope dissociation can cause a large impendence contrast and may partially account for the observed discontinuities below 660 km at the subduction zone. Combining our calculations with results from the previous study, we suggest that the incorporation of Al into bridgmanite shows no discernable effect on its elastic moduli and wave velocities. This may impede the detection of Al content in bridgmanite through seismological methods.
Local Seismicity of the Rainbow Massif on the Mid‐Atlantic Ridge

Published: January 2018

AbstractThe Rainbow massif, an oceanic core complex located in a nontransform discontinuity on the Mid‐Atlantic Ridge (36°N), is notable for hosting high‐temperature hydrothermal discharge through ultramafic rocks. Here we report results from a 9 month microearthquake survey conducted with a network of 13 ocean bottom seismometers deployed on and around the Rainbow massif as part of the MARINER experiment in 2013–2014. High rates (~300 per day) of low‐magnitude (average ML ~ 0.5) microearthquakes were detected beneath the massif. The hypocenters do not cluster along deeply penetrating fault surfaces and do not exhibit mainshock/aftershock sequences, supporting the hypothesis that the faulting associated with the exhumation of the massif is currently inactive. Instead, the hypocenters demarcate a diffuse zone of continuous, low‐magnitude deformation at relatively shallow (< ~3 km) depths beneath the massif, sandwiched in between the seafloor and seismic reflectors interpreted to be magmatic sills driving hydrothermal convection. Most of the seismicity is located in regions where seismic refraction data indicate serpentinized ultramafic host rock, and although the seismic network we deployed was not capable of constraining the focal mechanism of most events, our analysis suggests that serpentinization may play an important role in microearthquake generation at the Rainbow massif.
Endothelial Cells: Immunological Aspects
Authors: Cheung Kenneth CP , Ward Eleanor J , Fu Hongmei , Marelli‐Berg Federica M 
Published: January 2018

AbstractStrategically located at the interface between blood and the extravascular space, the endothelium is a highly specialised cellular system, which plays a key role in physiological processes such as blood supply, nutrient delivery, metabolic homeostasis and immune cell trafficking, as well as pathological processes such as inflammation. Endothelial cells represent a highly heterogeneous population of cells with the ability to interact with and modulate the function of immune cells. These cells regulate the traffic and functions of leucocytes by expressing adhesion molecules and cytokines in a regulated way. The ability of endothelial cells to compartmentalise memory T‐cell responses via organ‐selective expression of homing receptor ligands and to recruit antigen‐specific T cells into inflammatory sites by displaying cognate major histocompatibility complex–peptide complexes contributes a new dimension to the central role played by endothelium in the regulation of immune responses.Key ConceptsEndothelial cells are not just an inert barrier between the blood and parenchyma.The endothelial cell orchestrates cellular processes key to the inflammatory reaction.A regulated use of different adhesion molecules and chemokines guides tissue‐specific leucocyte extravasation.Especially, microvascular endothelial cells can act as antigen‐presenting cells, leading to T lymphocyte extravasation.Endothelial cells are both targets for and a source of cytokines – soluble polypeptides acting as mediators of communication with leucocytes and other cells.Vasculature senescence plays an active role in promoting an inflammatory response.
