Critical Newborn Screens in Double Heterozygotes of Inborn Errors of Metabolism—A Clinical Report and Recommendations
Authors: Langley Katherine , Chisholm Elizabeth , Spangler Brooke , Strovel Erin , Macdonald Jennifer , Vergano Samantha
Published: November 2016

The practice of newborn screening has been in place in the USA since the 1960s, with individual states initially screening for different numbers of disorders. In the early 2000s many efforts were made to standardize the various disorders being screened. Currently, there are at least 34 disorders that each state is mandated to include on their screening panel. Of those 34 disorders, the majority are inborn errors of metabolism (IEM) which include urea cycle disorders (UCD), citrullinemia (CIT) and argininosuccinic aciduria (ASA), as well as a number of fatty acid oxidation disorders. We present here four cases of infants who had critical newborn screens (NBS) in the Commonwealth of Virginia and underwent genetic testing because their clinical presentation and follow-up laboratory studies were not consistent with the disorder that was flagged by NBS. These newborns were found to be carriers for two different IEMs (in three cases) or compound heterozygotes (in one case). Currently no guidelines exist with respect to the appropriate way to manage these children who may or may not be symptomatic in the newborn period. We propose some general recommendations for management based on our experience with these four probands, and discuss the necessity for further conversation and collaboration between physicians encountering these not-so-infrequent presentations.
Adjustable Bézier Curves with Simple Geometric Continuity Conditions
Authors: Yan Lanlan
Published: November 2016

This paper aims to simplify the continuity conditions of Bézier curves. For this purpose, a special family of Bézier curves with three parameters, to be called adjustable Bézier curves, is constructed. They have the same structure as the quartic Bézier curves. The newly constructed curves possess some of the basic properties of Bézier curves, such as the convex hull property, symmetry, geometric invariance, etc., and they have shape adjustability. Moreover, under the geometric continuity of order 1 ( G 1 ) conditions of the usual Bézier curves, the adjustable Bézier curves can reach geometric continuity of order k ( G k ); here, k is one of the parameters of the newly constructed curves. The recursive evaluation algorithm of the new curves is provided. We also discuss how to construct the adjustable Bézier curves with a given tangent polygon. Numerical examples illustrate the correctness and validity of the proposed method.
Solving a Fabrication Lot-Size and Shipping Frequency Problem with an Outsourcing Policy and Random Scrap
Authors: Chiu Yuan-Shyi , Liang Gang-Ming , Chiu Singa
Published: November 2016

Operating in unstable and competitive globalized markets, management of today’s transnational enterprises continually searches for different alternatives to maintain product quality, streamline production activities, and reduce overall operating costs, particularly in their internal supply chain system. With the aim of revealing and offering insight information to support managerial decision making, this study explores the optimal replenishment lot-size and shipping frequency problem for an intra-supply chain system with a partial outsourcing policy and random scrap. In this study, the demand of a product is partially outsourced and partially fabricated by the production units, to release the workload of machine and smooth production schedule. During the fabrication process, a portion of random scrap items is produced, and finished products are distributed to sales locations using a multiple-shipment policy. The objective is to simultaneously determine an optimal fabrication lot-size and shipping frequency decisions that minimize the overall expected costs for such an intra-supply chain system. Mathematical modeling and optimization methods are used to solve the problem. Moreover, through the use of a numerical example and sensitivity analyses, various important insights with regard to the joint effects of the partial outsourcing policy and random scrap on the optimal solutions are revealed to support managerial decision making.

Published: November 2016

Tyrosinase is the rate-limiting enzyme critical for melanin synthesis and controls pigmentation in the skin. The inhibition of tyrosinase is currently the most common approach for the development of skin-whitening cosmetics. Gagunin D (GD), a highly oxygenated diterpenoid isolated from the marine sponge Phorbas sp., has exhibited cytotoxicity toward human leukemia cells. However, the effect of GD on normal cells and the molecular mechanisms remain to be elucidated. In the present study, we identified for the first time the anti-melanogenic activity of GD and its precise underlying mechanisms in mouse melan-a cells. GD significantly inhibited melanin synthesis in the melan-a cells and a reconstructed human skin model. Further analysis revealed that GD suppressed the expression of tyrosinase and increased the rate of tyrosinase degradation. GD also inhibited tyrosinase enzymatic activity. In addition, GD effectively suppressed the expression of proteins associated with melanosome transfer. These findings suggest that GD is a potential candidate for cosmetic formulations due to its multi-functional properties.
Transdermal Permeation and Anti-Inflammation Activities of Novel Sinomenine Derivatives
Authors: Zhao Zi-Jian , Zhao Chang , Xiao Jing , Wang Jian-Cheng
Published: November 2016

Sinomenine is extracted from Sinomenii caulis (a traditional Chinese medicine), and it is used as the active ingredient in rheumatic arthritis treatments. It has been used in clinical applications for decades. However, there are some disadvantages, including low activity in transdermal permeation and a high dosage being clinically required. To overcome these defects, sinomenine was used as a primer, and structural modification was performed. In our study, eight new compounds were screened out by transdermal permeation in vitro and anti-inflammatory response in vitro and in vivo. Compound 1a exhibited the most potent transdermal permeation and anti-inflammatory activity. Based on these results, further development of this compound may be warranted.
An Exploratory Investigation of Endotoxin Levels in Novice Long Distance Triathletes, and the Effects of a Multi-Strain Probiotic/Prebiotic, Antioxidant Intervention
Authors: Roberts Justin , Suckling Craig , Peedle Georgia , Murphy Joseph , Dawkins Tony , Roberts Michael
Published: November 2016

Gastrointestinal (GI) ischemia during exercise is associated with luminal permeability and increased systemic lipopolysaccharides (LPS). This study aimed to assess the impact of a multistrain pro/prebiotic/antioxidant intervention on endotoxin unit levels and GI permeability in recreational athletes. Thirty healthy participants (25 males, 5 females) were randomly assigned either a multistrain pro/prebiotic/antioxidant (LAB4ANTI; 30 billion CFU·day−1 containing 10 billion CFU·day−1 Lactobacillus acidophilus CUL-60 (NCIMB 30157), 10 billion CFU·day−1 Lactobacillus acidophillus CUL-21 (NCIMB 30156), 9.5 billion CFU·day−1 Bifidobacterium bifidum CUL-20 (NCIMB 30172) and 0.5 billion CFU·day−1 Bifidobacterium animalis subspecies lactis CUL-34 (NCIMB 30153)/55.8 mg·day−1 fructooligosaccharides/ 400 mg·day−1 α-lipoic acid, 600 mg·day−1 N-acetyl-carnitine); matched pro/prebiotic (LAB4) or placebo (PL) for 12 weeks preceding a long-distance triathlon. Plasma endotoxin units (via Limulus amebocyte lysate chromogenic quantification) and GI permeability (via 5 h urinary lactulose (L): mannitol (M) recovery) were assessed at baseline, pre-race and six days post-race. Endotoxin unit levels were not significantly different between groups at baseline (LAB4ANTI: 8.20 ± 1.60 pg·mL−1; LAB4: 8.92 ± 1.20 pg·mL−1; PL: 9.72 ± 2.42 pg·mL−1). The use of a 12-week LAB4ANTI intervention significantly reduced endotoxin units both pre-race (4.37 ± 0.51 pg·mL−1) and six days post-race (5.18 ± 0.57 pg·mL−1; p = 0.03, ηp2 = 0.35), but only six days post-race with LAB4 (5.01 ± 0.28 pg·mL−1; p = 0.01, ηp2 = 0.43). In contrast, endotoxin units remained unchanged with PL. L:M significantly increased from 0.01 ± 0.01 at baseline to 0.06 ± 0.01 with PL only (p = 0.004, ηp2 = 0.51). Mean race times (h:min:s) were not statistically different between groups despite faster times with both pro/prebiotoic groups (LAB4ANTI: 13:17:07 ± 0:34:48; LAB4: 12:47:13 ± 0:25:06; PL: 14:12:51 ± 0:29:54; p > 0.05). Combined multistrain pro/prebiotic use may reduce endotoxin unit levels, with LAB4ANTI potentially conferring an additive effect via combined GI modulation and antioxidant protection.
Arabidopsis Regenerating Protoplast: A Powerful Model System for Combining the Proteomics of Cell Wall Proteins and the Visualization of Cell Wall Dynamics
Authors: Yokoyama Ryusuke , Kuki Hiroaki , Kuroha Takeshi , Nishitani Kazuhiko
Published: November 2016

The development of a range of sub-proteomic approaches to the plant cell wall has identified many of the cell wall proteins. However, it remains difficult to elucidate the precise biological role of each protein and the cell wall dynamics driven by their actions. The plant protoplast provides an excellent means not only for characterizing cell wall proteins, but also for visualizing the dynamics of cell wall regeneration, during which cell wall proteins are secreted. It therefore offers a unique opportunity to investigate the de novo construction process of the cell wall. This review deals with sub-proteomic approaches to the plant cell wall through the use of protoplasts, a methodology that will provide the basis for further exploration of cell wall proteins and cell wall dynamics.
Evaluation of the Quality of NDVI3g Dataset against Collection 6 MODIS NDVI in Central Europe between 2000 and 2013
Authors: Kern Anikó , Marjanović Hrvoje , Barcza Zoltán
Published: November 2016

Remote sensing provides invaluable insight into the dynamics of vegetation with global coverage and reasonable temporal resolution. Normalized Difference Vegetation Index (NDVI) is widely used to study vegetation greenness, production, phenology and the responses of ecosystems to climate fluctuations. The extended global NDVI3g dataset created by Global Inventory Modeling and Mapping Studies (GIMMS) has an exceptional 32 years temporal coverage. Due to the methodology that was used to create NDVI3g inherent noise and uncertainty is present in the dataset. To evaluate the accuracy and uncertainty of application of NDVI3g at regional scale we used Collection-6 data from the MODerate resolution Imaging Spectroradiometer (MODIS) sensor on board satellite Terra as a reference. After noise filtering, statistical harmonization of the NDVI3g dataset was performed for Central Europe based on MOD13 NDVI. Mean seasonal NDVI profiles, start, end and length of the growing season, magnitude and timing of peak NDVI were calculated from NDVI3g (original, noise filtered and harmonized) and MODIS NDVI and compared with each other. NDVI anomalies were also compared and evaluated using simple climate sensitivity metrics. The results showed that (1) the original NDVI3g has limited applicability in Central Europe, which was also implied by the significant disagreement between the NDVI3g and MODIS NDVI datasets; (2) the harmonization of NDVI3g with MODIS NDVI is promising since the newly created dataset showed improved quality for diverse vegetation metrics. For NDVI anomaly detection NDVI3g showed limited applicability, even after harmonization. Climate–NDVI relationships are not represented well by NDVI3g. The presented results can help researchers to assess the expected quality of the NDVI3g-based studies in Central Europe.

Authors: Shirazi Muhammad , Kim Pilun , Jeon Mansik , Kim Jeehyun
Published: November 2016

We report a wavelength swept laser-based full-field optical coherence tomography for measuring the surfaces and thicknesses of refractive and reflective samples. The system consists of a galvo filter–based wavelength swept laser and a simple Michelson interferometer. Combinations of the reflective and refractive samples are used to demonstrate the performance of the system. By synchronizing the camera with the source, the cross-sectional information of the samples can be seen after each sweep of the swept source. This system can be effective for the thickness measurement of optical thin films as well as for the depth investigation of samples in industrial applications. A resolution target with a glass cover slip and a step height standard target are imaged, showing the cross-sectional and topographical information of the samples.

Published: November 2016

This paper presents a multi-axis force/torque sensor based on simply-supported beam and optoelectronic technology. The sensor’s main advantages are: (1) Low power consumption; (2) low-level noise in comparison with conventional methods of force sensing (e.g., using strain gauges); (3) the ability to be embedded into different mechanical structures; (4) miniaturisation; (5) simple manufacture and customisation to fit a wide-range of robot systems; and (6) low-cost fabrication and assembly of sensor structure. For these reasons, the proposed multi-axis force/torque sensor can be used in a wide range of application areas including medical robotics, manufacturing, and areas involving human–robot interaction. This paper shows the application of our concept of a force/torque sensor to flexible continuum manipulators: A cylindrical MIS (Minimally Invasive Surgery) robot, and includes its design, fabrication, and evaluation tests.
Household Structure and Suburbia Residence in U.S. Metropolitan Areas: Evidence from the American Housing Survey
Authors: Jung Gowoon , Yang Tse-Chuan
Published: November 2016

Suburbs have demographically diversified in terms of race, yet little research has been done on household structures in suburbs. Using the 2011 American Housing Survey and 2009–2013 American Community Survey, this study investigates the distributions of household structures in suburbia and central cities, and the relationship between household structures and residential attainment. The findings of this research include: (1) The distribution of household structures differs between suburbia and central cities. Married-couple households are the most common household type in both central cities and suburbs, but they are more likely to reside in suburbia than in central cities; (2) Household structure is a determinant of residential attainment and the relationship varies by race/ethnicity groups. Among Hispanics and Asians, multigenerational household structure is indicative of central city residence, but this association does not hold for whites and blacks. For multigenerational households, the odds of living in suburbia decreases by almost 40 percent among Hispanics and by almost 50 percent for Asians.
Spatial-Temporal Analysis on Spring Festival Travel Rush in China Based on Multisource Big Data
Authors: Li Jiwei , Ye Qingqing , Deng Xuankai , Liu Yaolin , Liu Yanfang
Published: November 2016

Spring Festival travel rush is a phenomenon in China that population travel intensively surges in a short time around Chinese Spring Festival. This phenomenon, which is a special one in the urbanization process of China, brings a large traffic burden and various kinds of social problems, thereby causing widespread public concern. This study investigates the spatial-temporal characteristics of Spring Festival travel rush in 2015 through time series analysis and complex network analysis based on multisource big travel data derived from Baidu, Tencent, and Qihoo. The main results are as follows: First, big travel data of Baidu and Tencent obtained from location-based services might be more accurate and scientific than that of Qihoo. Second, two travel peaks appeared at five days before and six days after the Spring Festival, respectively, and the travel valley appeared on the Spring Festival. The Spring Festival travel network at the provincial scale did not have small-world and scale-free characteristics. Instead, the travel network showed a multicenter characteristic and a significant geographic clustering characteristic. Moreover, some travel path chains played a leading role in the network. Third, economic and social factors had more influence on the travel network than geographical location factors. The problem of Spring Festival travel rush will not be effectively improved in a short time because of the unbalanced urban-rural development and the unbalanced regional development. However, the development of the modern high-speed transport system and the modern information and communication technology can alleviate problems brought by Spring Festival travel rush. We suggest that a unified real-time traffic platform for Spring Festival travel rush should be established through the government's integration of mobile big data and the official authority data of the transportation department.
An Improved Protocol for the Password Authenticated Association of IEEE 802.15.6 Standard That Alleviates Computational Burden on the Node
Authors: Zhang Jie , Huang Xin , Craig Paul , Marshall Alan , Liu Dawei
Published: November 2016

The IEEE Std 802.15.6 is an international standard for wireless body area networks (WBANs). It contains many aspects of communications, and also provides security services, since some communications in WBANs can carry sensitive information. In this standard, the password authenticated association is a protocol for two participants to identify each other and establish a new master key based on a pre-shared short password. However, recent research shows that this protocol is vulnerable to several attacks. In this paper, we propose an improved protocol which can resist all of these attacks. Moreover, the improved protocol alleviates computational burden on one side of the two participants, the node, which is usually less powerful compared with the other side, the hub.
Nutritional Stress Causes Heterogeneous Relationships with Multi-Trait FA in Lesser Black-Backed Gull Chicks: An Aviary Experiment
Authors: Gupta Trisha , Santos Cátia , Sotillo Alejandro , De Neve Liesbeth , Stienen Eric , Müller Wendt , Lens Luc
Published: November 2016

Environmental stressors have the potential to induce perturbations in the development of young individuals, leading to aberrant and unstable development. This may manifest as fluctuating asymmetry (FA; small, non-directional changes in the bilateral symmetry of morphological traits). Although widely regarded as a proxy for stress effects, the use of FA as a biomarker is still a topic of much debate. We investigated the applicability of FA as an indicator of nutritional stress (brought about by energetic constraints) by experimental manipulation of the diet composition and quantity during the growth of Lesser Black-backed Gull (Larus fuscus) chicks. FA as an endpoint was measured across the tarsus, wing and 10th primary feather when chicks reached 30 days of age. Although levels of asymmetry were found to increase with stress in the feather, relationships with tarsus and wing FA were mixed and mostly non-significant. Furthermore, we did not find any correlations in unsigned FA between traits, indicating the absence of organism-wide asymmetry. Our study was therefore unable to find unequivocal evidence in support of the application of FA as a reliable estimator of nutritional stress.
Extent of Stream Burial and Relationships to Watershed Area, Topography, and Impervious Surface Area
Authors: Weitzell Roy , Kaushal Sujay , Lynch Loretta , Guinn Steven , Elmore Andrew
Published: November 2016

Stream burial—the routing of streams through culverts, pipes, and concrete lined channels, or simply paving them over—is common during urbanization, and disproportionately affects small, headwater streams. Burial undermines the physical and chemical processes governing life in streams, with consequences for water quality and quantity that may amplify from headwaters to downstream receiving waters. Knowledge of the extent of stream burial is critical for understanding cumulative impacts to stream networks, and for future decision-making allowing for urban development while protecting ecosystem function. We predicted stream burial across the urbanizing Potomac River Basin (USA) for each 10-m stream segment in the basin from medium-resolution impervious cover data and training observations obtained from high-resolution aerial photography in a GIS. Results were analyzed across a range in spatial aggregation, including counties and independent cities, small watersheds, and regular spatial grids. Stream burial was generally correlated with total impervious surface area (ISA), with areas exhibiting ISA above 30% often subject to elevated ratios of stream burial. Recurring patterns in burial predictions related to catchment area and topographic slope were also detected. We discuss these results in the context of physiographic constraints on stream location and urban development, including implications for environmental management of aquatic resources.

Sur une anomalie pigmentaire de la grenouille verte (Rana esculenta) et de quelques autres amphibiens Anoures et Urodèlespar
Authors: Dubois Alain , Vachard Daniel
Published: November 2016

Résumé

L'anomalie N de la Grenouille verte (Rana esculenta ) est une anomalie pigmentaire qui se caractérise comme suit :

— chez l'imago à peine métamorphosé, l'iris de l'un ou des deux yeux est brun foncé, le dos noir-olivâtre, le ventre translucide ;

— par la suite, il peut y avoir soit retour rapide à une pigmentation totalement normale, sauf pour l'iris, soit conservation de la pigmentation anormale, avec apparition de diverses taches : taches blanchâtres, grisâtres ou noirâtres sur le ventre, taches dorées ou jaunes sur le dos.

L'étude de plusieurs de ces Grenouilles aux yeux noirs, ainsi que différents textes, plus ou moins récents, faisant mention de cette anomalie, permettent de formuler l'hypothèse selon laquelle celle-ci serait déterminée par des gènes multiples.

Des anomalies comparables ont déjà été décrites, ou sont décrites par nous, chez d'autres espèces d'Amphibiens Anoures et Urodèles. Les animaux atteints ont l'iris de l'un ou des deux yeux partiellement ou totalement noir ; la coloration du corps est normale dans certains cas, anormale dans d'autres.

Tant qu'elles ne sont pas mieux connues, nous proposons de regrouper ces anomalies pigmentaires sous le nom général d' «anomalie N ».

L'étude d'un abondant matériel nous a permis d'arriver à l'hypothèse que l'espèce Aphodius mixtus Villa pouvait être considérée comme constituée de trois sous-espèces ; la ssp. nominative occupe toute (?) la chaîne des Alpes, et les deux autres, pécoudi (Hoffm.) m. et balazuci nov. habitent respectivement les Pyrénées et le Massif Central. Ces trois sous-espèces, très voisines, ne peuvent être séparées morphologiquement avec certitude que par l'examen des genitalia mâles, dont la constance justifie une telle conception.
How Tourist Attraction Agglomeration Affects a Regional Tourism Economy
Authors: Zhou Bo , Qu Hailin , Li Ningqiao
Published: November 2016

According to agglomeration theory, tourist attraction agglomeration can enhance the performance of tourism economy in a region. In contrast, industrial organization theory suggests that tourist attraction agglomeration can harm economic performance. This study examines the impact of
tourist attraction agglomeration on a regional tourism economy using empirical evidence. China has experienced a proliferation of tourist attractions in the last 15 years. In 2000, only 590 A-class tourist attractions were part of the tourism market; however, by 2012, the number of A-class
tourist attractions had increased to 6,042, providing a good opportunity for estimating the impact of agglomeration. The study results show a positive relationship between tourist attraction agglomeration and the performance of a regional tourism economy, suggesting that agglomeration theory
holds up in the real world. Some implications for regional tourism planning and tourism development are derived.
The Emergence of “Small-Scale” Sport Events in “Small Island” Developing States: Towards Creating Sustainable Outcomes for Island Communities
Authors: Ziakas Vassilios , Boukas Nikolaos
Published: November 2016

Although academic literature has examined sport events in urban and rural communities, there is limited research on the forces and dynamics that influence the sustainability of sport events in islands. Cyprus represents a small island developing state with an embryonic event industry,
which poses the question whether the emergence of new events can contribute to its sustainable development. The purpose of this study is to examine the impacts of two nascent sport events: the “Limassol Marathon” and the “Tour of Cyprus Cycling Challenge,” focusing
on their prospects for creating strategic outcomes that can contribute to the sustainability and rejuvenation of Cyprus as a tourism destination. The study employed a triangulation research technique through the application of mixed methods, conducting first semistructured interviews with
event organizers, and thereafter a survey examining the perceived experiences of event participants. Findings illustrate the interrelationships of new small-scale events that can amplify their synergistic value by enabling the achievement of multiple purposes. Implications are drawn concerning
the synergistic value of small-scale sport events and the strategic processes for creating a range of sustainable event outcomes.
Resident Valuation of Planned Events: An Event Portfolio Pilot Study
Authors: Gration David , Raciti Maria , Getz Donald , Andersson Tommy D.
Published: November 2016

Residents of the Sunshine Coast region in Queensland, Australia, were surveyed on the subject of planned events in their region with the main aim of determining how and why they value events. It was revealed that residents gained considerable use value from events that they attended
as audience or otherwise participated in, expressed strong support for a range of events (with a preference for community festivals), and overall did not believe that problems or costs were serious. Residents also indicated strong nonuse values (being existence, option,
and bequest values) for events in general. Our findings are positioned within the body of literature concerning impact assessment (specifically, resident perceptions and attitudes towards events), valuation (i.e., the worth of events), and policy and strategy concerning community events
and event tourism.

TORSIONAL DYNAMIC RESPONSE OF A CARBON NANOTUBE EMBEDDED IN VISCO-PASTERNAK’S MEDIUM
Authors: Zenkour Ashraf M.
Published: November 2016

The torsional dynamics of carbon nanotubes embedded in viscoelastic medium are presented by using the nonlocal elasticity theory. The medium is considered as a foundation model which characterized by the linear Winkler’s modulus, Pasternak’s (shear) foundation modulus and the damping coefficient. The governing torsional equation is obtained and solved for nanotubes subjected to various boundary conditions and stated under different loads. The effects of some parameters like nonlocal parameter, nanotube length, Winkler’s modulus, and damping coefficient on the angular displacement of the nanotube are investigated in detail. The angular displacements are very sensitive to all parameters, especially the inclusion of the viscous damping foundation. Present results can be useful in design of future nano composites, nano electromechanical systems like nano position sensors and linear servomotors. Sample angular displacements are tabulated and plotted for sensing the effect of all used parameters and to investigate the visco-Pasternak’s parameters for future comparisons.
MIXING THE SOLAR WIND PROTON AND ELECTRON SCALES: EFFECTS OF ELECTRON TEMPERATURE ANISOTROPY ON THE OBLIQUE PROTON FIREHOSE INSTABILITY
Authors: Maneva Y. , Lazar M. , Viñas A. , Poedts S.
Published: November 2016

The double adiabatic expansion of the nearly collisionless solar wind plasma creates conditions for the firehose instability to develop and efficiently prevent the further increase of the plasma temperature in the direction parallel to the interplanetary magnetic field. The conditions imposed by the firehose instability have been extensively studied using idealized approaches that ignore the mutual effects of electrons and protons. Recently, more realistic approaches have been proposed that take into account the interplay between electrons and protons,  unveiling new regimes of the parallel oscillatory modes. However, for oblique wave propagation the instability develops distinct branches that grow much faster and may therefore be more efficient than the parallel firehose instability in constraining the temperature anisotropy of the plasma particles. This paper reports for the first time on the effects of electron plasma properties on the oblique proton firehose (PFH) instability and provides a comprehensive vision of the entire unstable wave-vector spectrum, unifying the proton and the smaller electron scales. The plasma β and temperature anisotropy regimes considered here are specific for the solar wind and magnetospheric conditions, and enable the electrons and protons to interact via the excited electromagnetic fluctuations. For the selected parameters, simultaneous electron and PFH instabilities can be observed with a dispersion spectrum of the electron firehose (EFH) extending toward the proton scales. Growth rates of the PFH instability are markedly boosted by the anisotropic electrons, especially in the oblique direction where the EFH growth rates are orders of magnitude higher.
THE ORIGIN OF DOUBLE-PEAKED NARROW LINES IN ACTIVE GALACTIC NUCLEI. II. KINEMATIC CLASSIFICATIONS FOR THE POPULATION AT z < 0.1
Authors: Nevin R. , Comerford J. , Müller-Sánchez F. , Barrows R. , Cooper M.
Published: November 2016

We present optical long-slit observations of the complete sample of 71 Type 2 active galactic nuclei (AGNs) with double-peaked narrow emission lines at z < 0.1 in the Sloan Digital Sky Survey. Double-peaked emission lines are produced by a variety of mechanisms including disk rotation, kiloparsec-scale dual AGNs, and narrow-line region (NLR) kinematics (outflows or inflows). We develop a novel kinematic classification technique to determine the nature of these objects using long-slit spectroscopy alone. We determine that 86% of the double-peaked profiles are produced by moderate-luminosity AGN outflows, 6% are produced by rotation, and 8% are ambiguous. While we are unable to directly identify dual AGNs with long-slit data alone, we explore their potential kinematic classifications with this method. We also find a positive correlation between the NLR size and luminosity of the AGN NLRs (R

DISTANCE-DEPENDENT OFFSETS BETWEEN PARALLAXES FOR NEARBY STARS AND GAIA DR1 PARALLAXES
Authors: Jao (饒惟君) Wei-Chun , Henry Todd J. , Riedel Adric R. , Winters Jennifer G. , Slatten Kenneth J. , Gies Douglas R.
Published: November 2016

We use 612 single stars with previously published trigonometric parallaxes placing them within 25 pc to evaluate parallaxes released in Gaia’s first data release (DR1). We find that the Gaia parallaxes are, on average, 0.24 ± 0.02 mas smaller than the weighted mean trigonometric parallax values for these stars in the solar neighborhood. We also find that the offset changes with distance out to 100 pc, in the sense that the closer the star, the larger the offset. We find no systematic trends in the parallax offsets with stellar V magnitude, V − K color, or proper motion. We do find that the offset is roughly twice as large for stars south of the ecliptic compared to those that are north.
Two new records of palm species for Gabon: Sclerosperma profizianum Valk. & Sunder. and Eremospatha quiquecostulata Becc.

Published: November 2016

Gabon is an important center of biodiversity in Central Africa. The country contains to date 27 species of palms. However, palms are generally poorly collected as these massive plants are hard to press and curate. Thus, our understanding remains incomplete, especially in Central Africa.

We report three new records of two palm species for Gabon: Sclerosperma profizianum Valk. & Sunder. and Eremospatha quiquecostulata Becc.. The former species was collected in southeast Gabon, near Ndindi, while the later was collected in the Massif du Chaillu and Monts de Cristal National Park (Crystal Mountains National Park). The total number of palm species for Gabon is now 29, making it an important centre of palm diversity in Central Africa.

Le dévoilement du corps et le monde antérieur chez Jung et Pauli
Authors: Traversi Bruno
Published: November 2016

La question du corps chez Carl Gustav Jung s’enracine dans sa théorie d’un « monde antérieur », dans lequel la sphère physique et la sphère psychique ne sont pas encore distinctes, et qui est au soubassement de la réalité telle qu’elle se donne à nous ordinairement – théorie qu’il façonne avec Wolfgang Pauli, l’un des pères de la mécanique quantique. Questionner le corps dans une perspective jungienne exige alors de comprendre le développement de ce plan fondamental en notre plan d’existence ordinaire où les sphères physique et psychique sont distinctes et s’opposent. L’accès à ce monde antérieur exige un enfouissement qui permet de mettre au jour des faits d’un nouveau genre pour lesquels les césures entre intériorité et extériorité, entre sujet et objet, ne sont plus valables. En alchimie et dans le yoga, cet enfouissement en soi se double de phénomènes d’extériorisations qui modifient le corps et son environnement. À l’occasion de ces extériorisations se révèle un corps originel capable de refléter et d’explorer les objets de la psyché.
Le mécanisme organique : À propos de la réception de Leibniz par Bourguet
Authors: Duchesneau François
Published: November 2016

Correspondant de Leibniz, philosophe professant à Neuchâtel, Louis Bourguet (1678-1742) se fit l’interprète des vues de Leibniz sur le rapport entre monade et corps organique. Dans ses Lettres philosophiques (1729), il ne se contente pas d’analyser et de critiquer les diverses hypothèses relatives à la génération telles qu’on les soutenait à l’époque, mais il repense à nouveaux frais les arguments en faveur de la préformation et il réinsère la doctrine de l’« organisme » dans un cadre théorique inspiré de la monadologie. Il définit ainsi, sous le vocable de « mécanisme organique », des principes aptes à régir les recherches de philo­sophie expérimentale sur le vivant. Il adapte de diverses façons les thèses leibniziennes et ouvre ainsi la voie à des évolutions marquantes du concept de corps organique au xviii e   siècle.
« Autant de mondes sans connexion » : Leibniz et Lewis sur la compossibilité et l’unité du monde
Authors: Anfray Jean-Pascal
Published: November 2016

La compossibilité chez Leibniz est la relation qui répartit les possibles en mondes distincts. Un problème central consiste à comprendre pour quelle raison tous les possibles ne sont pas compossibles, ou ce qui fonde la pluralité des mondes possibles. On examine ici ce problème en confrontant les thèses de Leibniz au réalisme modal de Lewis. Chez ce dernier, l’appartenance à un même monde est définie par l’existence de relations spatiotemporelles, ce qui exclut la possibilité d’univers-îles, ou mondes sans connexion spatiotemporelle et permet de conclure à l’impossibilité qu’un monde contienne la totalité des possibles. L’interprétation cosmologique de la compossibilité attribue une position semblable à Leibniz. Mais cette interprétation exige de tenir l’harmonie expressive pour une caractéristique nécessaire de tous les mondes, ce qui est incompatible avec un certain nombre d’affirmations de Leibniz.
Dynamica abstracta et dynamica concreta
Authors: Costa Andrea
Published: November 2016

La bipartition entre une dynamica abstracta et une dynamica concreta est récurrente dans la production scientifique leibnizienne en dépit des acquisitions conceptuelles qui – dès la rédaction de la Dynamica de Potentia de 1690 – permettraient de la dépasser. S’appuyant sur l’étude des manuscrits inédits réalisée en vue de la publication de la première édition critique du traité, l’article se propose : 1. d’explorer les raisons de la permanence d’une telle structure à la lumière des travaux logiques et grammaticaux leibniziens sur l’abstrait et le concret – 2. d’offrir au lecteur une contextualisation et une présentation générale de l’œuvre, ainsi qu’un aperçu du nouveau matériau éditorial disponible.
Identifying Critical Factors in Determining Discharge Readiness from Skilled Home Health: An Interprofessional Perspective
Authors: O'Connor Melissa , Moriarty Helene , Madden-Baer Rose , Bowles Kathryn H.
Published: November 2016

A lack of readiness for discharge from skilled home health can result in adverse events among older adults. The purpose of the current study was to explore interprofessional home health clinician perceptions of the factors they consider important to determine readiness for discharge among skilled home health recipients. A qualitative descriptive study was conducted using four focus groups among 32 interprofessional clinicians from one large skilled home health agency and two telephone interviews with home visiting physicians. A semi-structured interview guide was followed. Qualitative content analysis was used for manifest coding and then thematic analysis. Five themes emerged: (a)
patient safety
, (b)
long-term plan is in place
, (c)
reached maximum self-care potential
, (d)
presence of a willing and able caregiver
, and (e)
patient attributes
. The goal of this line of inquiry is to develop an evidence-based home health discharge decision support tool to provide a standardized approach in determining readiness for discharge from skilled home health services.

Ouverture d'une enquête à l'initiative du Procureur sur la situation en Géorgie
Authors: Nollez-Goldbach Raphaëlle
Published: November 2016

Par une décision du 27 janvier 2016, la Chambre préliminaire de la Cour pénale internationale a autorisé la Procureure à ouvrir une enquête sur les crimes de guerre et les crimes contre l'humanité commis en Ossétie du Sud et ses alentours, entre le 1er juillet et le 10 octobre 2008. C'est la troisième fois que le Procureur ouvre une enquête de sa propre initiative. Les deux précédentes situations concernaient le Kenya en 2010 et la Côte d'Ivoire en 2011. Il s'agit surtout de la première situation non-africaine à la CPI. D'où l'importance symbolique non négligeable d'une telle enquête, alors que la CPI a fait l'objet de critiques virulentes pour ne juger depuis sa création que des accusés africains. Cette enquête, qui pourrait mener à la mise en accusation à la fois de ressortissants géorgiens mais aussi russes, constitue un immense défi pour la CPI. La Russie a d'ailleurs annoncé le 16 novembre dernier qu'elle allait retirer sa signature du Traité de Rome instituant la Cour.
Corporate Social Responsibility and Corporate Governance
Authors: López-Fernández Andrée Marie
Published: November 2016

Corporate Social Responsibility (CSR) and corporate governance are two distinct concepts that may seem to be isolated in practice. However, there are many parallels to the extent that the latter may define the engagement of the former. As such, it may be argued that corporate governance is essential to the implementation of CSR. Thus, a question arises, are firms' governance policies conducive to the engagement in corporate social responsibility? This study aims to evaluate the dynamics between corporate social responsibility and corporate governance of multinational firms operating in Mexico. Findings indicate that the practice of disclosing corporate social responsibility is more common than the transparent communication of corporate governance; however, the compliance with corporate governance is consistent with that of corporate social responsibility within the analysed firms.
Fuzzy Sets, Intuitionistic Fuzzy Sets
Authors: Bhowmik Monoranjan , Pal Madhumangal
Published: November 2016

In this chapter, we define four separations of generalized interval-valued intuitionistic fuzzy sets (GIVIFSs). In fact, all interval-valued Intuitionistic fuzzy sets (IVIFSs) are GIVIFSs but all GIVIFSs are not IVIFSs. Also, we studied some properties of the four separated subsets of GIVIFSs.
Gendered Leadership as a Key to Business Success
Authors: Marinakou Evangelia , Giousmpasoglou Charalampos
Published: November 2016

Although there is clear evidence of the importance of women in leadership positions, research still shows that women are still underrepresented in management and leadership roles. The percentage of women directors in Fortune 500 companies has been between 16% and 17% since 2011. This lack of women in senior management positions demonstrates that organizations still fail to notice that leadership nowadays has new requirements. Today's organizations are facing a turbulent constantly changing environment, in an open, social and interdependent economy, which requires specific skills and competencies for leading the change. Hence companies should value women's talent. The purpose of this chapter is to present gender issues in leadership and management with a focus on the Arab context and the position of women in the Middle East (ME). Finally, it discusses the most effective leadership style exhibited by male and female managers in the ME for inclusion in HR practices and strategies for the new millennia workforce. The main concerns are HR practices and examples in the ME.
Insights and Rumination of Human Resource Management Practices in SMEs

This chapter focuses on some specific areas of human resource management (employee relations, psychological contract, recruitment and selection) in a small - scale family owned travel agency. The study conducted via qualitative approach and using interviews and observations. Results show that, in a situation, where a sort of typical family relation exists between the owners/management, external employees are less likely offered any form of preferences; even this person possessed two criteria as qualifications or experiences and innate abilities.
Becoming Responsive Teachers during a Practicum-Based Study Abroad Experience
Authors: Dozier Cheryl L. , Stephens S. Joy
Published: November 2016

This chapter shares the planning, design, and implementation of a unique, intensive practicum based faculty-led study abroad program for preservice candidates in village and town schools in Belize, Central America. This study abroad experience included cultural explorations, school-based writing practicum experiences, and daily seminar sessions. In communities of writers, preservice candidates focused on learning from and with Belize learners and families as they developed as responsive teachers. The authors designed engagements to mentor preservice candidates in strengths based teaching, creating side-by-side writing communities, developing purposeful and intentional instructional language, and learning from students' families. Reflecting on two consecutive trips during the university's winter semester, the authors share insights on re-imagining educational and travel narratives. They also discuss ways they continue to learn from participants as they design future trips.
Instructional Videos as ICT for Teacher Professional Development
Authors: Semich George W. , Copper Jenna
Published: November 2016

Information Communication Technologies have had a major impact in education today. Various ICT tools have been used to produce very favorable outcomes in terms of student learning. One such tool is YouTube which has had a dynamic influence on teaching and learning and is widely used by teachers in the classroom. The focus of this study is to examine how teachers would respond to the use of ICT tools, namely YouTube, as a form of delivery for their own staff development training. In this study, we surveyed teachers to assess their feelings on this form of training. Our findings showed a favorable response to this form of training using YouTube and demonstrated a rationale supported by a list of themes related to their rationale for favoring this choice.
Using the Medicine Wheel for Curriculum Design in Intercultural Communication
Authors: LaFever Marcella
Published: November 2016

In December 2015, the Truth and Reconciliation Commission of Canada released its calls to action for reconciliation related to the oppressive legacy of Indian Residential Schools. Required actions include increased teaching of intercultural competencies and incorporation of indigenous ways of knowing and learning. Intercultural Communication as a discipline has primarily been developed from euro-centric traditions based in three domains of learning referred to as Bloom's taxonomy. Scholars and practitioners have increasingly identified problems in the way that intercultural competency is taught. The decolonization of education is implicated in finding solutions to those problems. Indigenization of education is one such effort. This chapter posits the Medicine Wheel, a teaching/learning framework that has widespread use in indigenous communities, for use in instructing intercultural communication. Bloom's taxonomy of the cognitive, psychomotor, and affective domains, is missing the fourth quadrant of the Medicine Wheel, spiritual. Examples of the spiritual quadrant are offered.
