Effect of Pollination Method on Changes in Physical and Chemical Characteristics of Date Fruit During Development
Authors: EIMardi M.O. , Esechie H. , Al-Kharousi L.M. , Abdelbasit K.M.
Published: June 2017

Date palms were pollinated by hand, hand duster and motorized duster. Pollen for the hand and motorized dusters was diluted with wheat flour each at 1:5, 1:7, 1:9 and 1:14 ratios. Fruit samples were collected during ‘Hababook’, ‘Kimri’, ‘Bisir’, ‘Rutab’, and ‘Tamr’ stages. Chemical and physical characteristics were determined in the laboratory. The motorized duster produced lower fruit set than the hand duster. No significant effect of pollination method on yield was observed. None of the physical or chemical differences that appeared during the same stage of fi'uit development proved to be an indicator of maturity. During ‘Kimri’, more fiuits with higher pectin (late maturing) were produced by the motorized duster than those produced by hand pollination and hand duster. But the motorized duster produced fi'uits with larger volume (i.e. ‘Rutab’ and ‘Tarnr’) than those of hand pollination. However, the reduction in acidity between ‘Bisir’ and ‘Rutab’ and in volume between ‘Rutab’ and ‘Tamr’ clearly indicated early maturity of the hand-pollinated fruits. The reduction in acidity between ‘Rutab’ and ‘Tamr’ indicated that hand-pollinated fruits ripen at a slower rate than the fruits of mechanized pollination at any of the pollen to flour ratios. The latter case could be attributed to the conversion of the acids to the dark pigmentation of ‘Tamr’. The lowest pollen : flour ratio (1:14) produced the lowest yield, moderate Fruit set and highest dry matter, whereas the highest ratio (1:5) produced a lower sucrose and dry matter and higher yield.

Authors: Alahmed A.M. , Kheir S.M.
Published: June 2017

The life cycle of Hyalomma dromedarii Koch (Acari:Ixodidae) on rabbits at 25 and 32ºC was compared at 85% R.H. At these temperatures, it behaved as a two-host tick and completed its life cycle in 108-146 and 80-115 days, respectively. The preoviposition, incubation and moulting periods varied significantly and were influenced by temperature. The survival periods of different developmental stages of Hyalomma dromedarii at 25ºC, 32, 38, 43, and 48ºC at 85% R.H. were investigated. The eggs, engorged nymphs and engorged females died at 38ºC, and the unfed larvae died at 43ºC. The longevity of the unfed adults decreased from 90-120 days at 25ºC to7-15 days at 43ºC. They died at 48ºC. These results suggest that the survival periods of eggs, engorged nymphs and engorged females were significantly decreased with an increase in temperature. They were more susceptible to high temperature than unfed adults. The role of unfed adult in the continuity of the life cycle of the tick throughout the year is discussed.

Authors: Abdullah G. R. , Al-Khateeb A.A. , Serage M.
Published: June 2017

Micropropagation techniques were set up for Gardenia jasminoides c.v. veitchi. Many plantlets were obtained by culturing shoot cuttings in MS nutrient media, 30 g/L Sucrose, 7 g/L Agar Agar, and different concentrations of BAP and IAA. The best concentration was 1mg /L BAP with 0.5 mg/L IAA. This concentration gave the best sprout growth suitable for rooting in primary and secondary culture by reculturing the stuck cutting every 6 weeks and for many times. We also obtained a high rooting percentage up to 98 % of natural rooting in rooting media different from propagation media by reducing mineral salt concentration to half, Sucrose to 20gm/L, and 2gm/L active charcoal, and 1mg/L IAA. Plantlets were transferred to greenhous and subjected for hardening. This technique gave 22 plantlets from one cutting in one year.

Published: June 2017

In recent years much concern has been given to toxic heavy metals, which enter the human food chain. Application of inorganic fertilizers is considered one of the potential routes of such entry, in this work 74 samples of commercial fertilizers marketed in the Kingdom of Saudi Arabia were analyzed for their heavy metal concentrations. Fertilizer samples included 20 samples of phosphatic fertilizers [monoammonium phosphate (MAP), diammonium phosphate (DAP) and triple superphosphate (TSP)], 11 samples of liquid fertilizers. 31 samples of water-soluble multiple nutrient fertilizers (WSMF) and 12 samples of solid multiple nutrient fertilizers (SMNF). Concentrations of heavy metals varied according to the type of fertilizer and the tested metal; Cr levels were the highest and Co was the lowest. Results revealed that Cd ranged from < l to 36.8 mg.kg-1, with a median of 33.2 mg.kg-1 for the phosphatic fertilizers, 9.5 mg.kg-1 for the liquid fertilizers, 19.7 for the SMNF, and 2.9 mg.kg-1 for the WSMF. The median values of Pb, Ni, Co and Cr in the phosphatic fertilizers were 14.3, 72.1, 1 1.8 and 249.3 mg.kg-1, respectively. However, the corresponding median values of these elements, in the liquid fertilizers, were 9.9, 15.6, 11.2 and 64.0 mg.kg-1 and 15.3, 43.0, 12.5 and 170.7 mg.kg-1 in the SMNF. The median contents of three heavy metals in the WSMF samples were 9.8 mg.kg-1 for Pb, 5.6 mg.kg-1 for Co. and 7.4 mg.kg-1 for Ni. The Cd. Co. Cr and Ni concentrations were lower than the tolerance limits for heavy metal addition (Cd 100 mg.kg-1, Cr, 100 mg.kg-1 and Ni, 50 mg.kg-1), and they were in a range similar to those found internationally. It is estimated that the application of an average dose of 80 kg P ha-1 annually in Saudi Arabia, contributes 13 g of Cd ha-1 to the soil.
Effect of Anoxia on Respiration Rate (Fermentative Index) and Ethanol Production of Onion Bulbs (Allium cepa L.)
Authors: Benkeblia N. , Shiomi N.
Published: June 2017

The physiological behavior, including carbon dioxide production, fermentative index (FI) and ethanolic production of onion bulbs kept under total anoxia (l00% N2) was investigated. During the first 24 hours, carbon dioxide production increased from 0.01 to 1.56 kPa Co2, and the average rate of the increase in CO2; production between 0 and 24 hours was 0.09 kPa/h. The Q10, of the fermentative index was l.9. Ethanol produced by onion bulbs kept under anoxia during 6 hours was temperature dependent, and was 0.563 and 0.760 pmol kg-1h-1 at 10 and 20°C respectively, while at 4°C the quantity produced was not detected. It is concluded that onion seems to be less tolerant to anoxia than other vegetables such as artichoke, cauliflower, tomato, potato and asparagus.
A universidade do significado: reflexões sobre as relações entre a Universidade Católica e Cultura a partir do Concílio Vaticano II
Authors: Nascimento Fernando Luís do
Published: June 2017

Inspirado pela Constituição Pastoral do Concílio Vaticano II Gaudium et Spes, o presente artigo considera como a universidade católica pode contribuir para um fecundo diálogo acerca das relações entre os pungentes avanços culturais das últimas décadas e a busca de sentido para a vida do homem contemporâneo. A hipótese do texto é que os conceitos de plano de vida e identidade narrativa hauridos das filosofia de Alasdair MacIntyre e Paul Ricoeur podem fornecer subsídios filosóficos importantes para uma reflexão sobre a integração saudável dos bem vindos progressos culturais, científicos e tecnológicos em um arcabouço de significado que privilegia a pessoa e a sociedade humana em todas suas dimensões.
Por uma economia mais solidária e sustentável em prol da vida humana menos egoísta
Authors: Gonçalves Dimas Alcides , Gonçalves Juliano Vieira
Published: June 2017

Insistimos na frase outrora posta na Carta da Terra de que o destino comum nos obriga a procurar um novo início, mesmo sabendo que, para a maioria da massa trabalhadora, a suposta verdade construída em prol do bem-estar social não se verifica. Tanto assim o é que ainda se observam os movimentos contrários às diferenças salariais entre homens e mulheres, à precarização das leis sociais do trabalho, ao desemprego estrutural para os jovens e uma completa desregulamentação trabalhista, de caráter global. Isso tudo por conta de alguns homens que, em sua ganância de querer, a todo instante, priorizar a maximização do lucro e de se escorar na racionalidade instrumental cega e, no desprezo pela multidimensionalidade do ser humano, acabam por fomentar a desigualdade desmedida dentro de sua própria espécie. Este artigo surge sim, para a preservação de nossa condição mais afetuosa que, até que enfim, tenta tornar-se ciente das consequências da sustentabilidade, podendo, assim, extrapolar para a dimensão do complemento imprescindível à causa da economia solidária, o tal “desenvolvimento sustentável”. Ambos os conceitos estão atrelados ao pensamento da necessidade urgente de subordinar o desenvolvimento econômico ao sistema da natureza, sempre limitado e permanentemente vinculado ao homem, enquanto ser humano e ser social. Não se deve mais desprezar a multidimensionalidade da criatura humana, reduzindo-a a mera ferramenta econômica a serviço do grande capital. Cá se fala um pouco da luta de classes, das relações de gênero, do jovem no mundo do trabalho, da segurança alimentar, da participação política, da cultura e, principalmente, do tipo de desenvolvimento econômico pleiteado em territórios, em sua maioria, locais (ainda). Tudo vale, desde que carregado de um forte componente de afetividade, de cuidados mútuos e de interação humana, muito além do já tão cravado aspecto econômico. E, felizmente, (pouco a pouco, como o próprio movimento cooperativista) bem menos egoísta.Palavras-chave: Afetividade. Economia solidária. Desenvolvimento local. Multidimensionalidade humana. Precarização do trabalho. Sustentabilidade.

Published: June 2017

O conto “Foram as dores que o mataram”, de Dina Salústio, escritora cabo verdiana, traz à lume uma discussão ímpar sobre a realidade de violência a que muitas mulheres estão subjugadas em algumas ilhas de Cabo Verde, mas também em diferentes rincões do mundo. À luz dos estudos e do conceito da Literatura e da Antropologia sobre esta realidade vivenciada por mulheres sofridas, silenciadas, decorrente do machismo e do patriarcado, este ensaio apresenta uma análise sobre violência de gênero que, através da narrativa contemporânea, anuncia um tipo de realidade que se abisma na lente de contato da inscritura africana. Nessa travessia, a artimanha de contar história vem traduzida pelo legado das culturas dos povos insulares.

Tooth impaction: A new variable in difficulty index of third molar extraction
Authors: Jaisaini Mehul Rajesh , Dongol A , Acharya P , Yadav AK
Published: June 2017

Third molar surgery is one of the major events carried out world-wide in a maxillofacial clinic. Preoperative assessment of surgical difficulty is fundamental to planning of extraction of impacted third molars. Various models for this assessment have been proposed but none is universally applicable. Although several studies have identified a plethora of factors associated with extraction difficulty, as measured via a wide variety of proxy variables, still, there are conflicting reports and wide variations of the enumerated factors. Adding to the existing knowledge, through this communication we would like to suggest that tooth impaction should also be considered as a variable of difficult third molar extraction. It requires both surgical expertise and added operating time thus affecting difficulty index.So we suggest tooth impaction should be considered as a difficulty assessment tool and studies be carried out to produce an evidence based database. Health Renaissance 2015;13(2): 180-182
Creole Language and Space: Entertaining Patrick Chamoiseau's Texaco
Authors: Radovic Stanka
Published: June 2017

My essay explores Martinican writer Patrick Chamoiseau's novel Texaco (1992) and its idea of a multilingual collective space where the communal resilience of the former slave population finds its expression in the productive encounter between Creole and French. Chamoiseau's revisionary historical novel counters the official history of colonial dislocation with the celebration of infiltration and squatting through which unauthorized communities, languages and histories demand to be accommodated. The linguistic and spatial assertion of the Creole community suggests that its place depends, to a large extent, on the narrative inscription of its communal experience. The very real economic limitations of the slum community do not amount to a flawed or incomplete sense of identity but trigger, instead, a collective struggle for group identity and collective ownership of space and self through the vibrancy and resourcefulness of multilingual and polyphonic narration.
Lire le relief: distance optique et histoire de la langue vulgaire entre Raymond Queneau et Pascale Casanova
Authors: Wishart James
Published: June 2017

Dans La République mondiale des lettres, Pascale Casanova revient sur l'importance de la formation des langues vulgaires, contre l'hégémonie littéraire du Latin, dans la construction progressive d'un espace mondial de la littérature. Cet article explore la résurgence de cette histoire dans le projet de « néo-français » de Raymond Queneau qui va jusqu’à penser son écriture de façon ironique comme invention d'une nouvelle langue vulgaire sur le modèle de Du Bellay. L'article retrace la dimension multilingue de ce projet exposé dans Bâtons, chiffres et lettres: du démotique grec à la traduction de Joyce par Queneau. Il montre comment l'alexandrin classique de la Petite cosmogonie portative devient paradoxalement une scène de représentation de la langue vulgaire et de ses vestiges. Le poème est le lieu où se déchiffre l'histoire conflictuelle réprimée de la République mondiale des lettres, mais aussi celui d'une expérience virtuelle de la langue, fictivement délestée des normes nationales.
Random Forest Prediction of IPO Underpricing
Authors: Quintana David , Sáez Yago , Isasi Pedro
Published: June 2017

The prediction of initial returns on initial public offerings (IPOs) is a complex matter. The independent variables identified in the literature mix strong and weak predictors, their explanatory power is limited, and samples include a sizable number of outliers. In this context, we suggest that random forests are a potentially powerful tool. In this paper, we benchmark this algorithm against a set of eight classic machine learning algorithms. The results of this comparison show that random forests outperform the alternatives in terms of mean and median predictive accuracy. The technique also provided the second smallest error variance among the stochastic algorithms. The experimental work also supports the potential of random forests for two practical applications: IPO pricing and IPO trading.
Levels of Organic Pollution Indicators in Groundwater at the Old Landfill and Waste Management Site
Authors: Koda Eugeniusz , Miszkowska Anna , Sieczka Anna
Published: June 2017

The aim of this paper was to assess groundwater quality in a landfill and waste management site, with special regard to levels of organic pollution indicators: chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total organic carbon (TOC). Analysis of specific indicators was conducted for piezometers located in the area of the Radiowo landfill, the composting plant and the facilities adjacent to the landfill. The article discusses the temporal and spatial changes of selected organic pollution indicators. Based on the results of groundwater monitoring, several maps of COD, BOD and TOC areal distribution were provided. Statistical distribution of monitoring data was presented using box-and-whisker plots. Pearson’s correlation coefficients between selected pollution indicators were measured with a significance level set at p < 0.01 and p < 0.05. The strongest correlation was observed between BOD and COD. The maximum BOD/COD ratio was observed at the level of 1.561 before the closure of the vertical barrier, whereas, at present, average values of this ratio are below 0.18. The results indicate significant improvement of groundwater quality in the landfill site after the closure of the vertical barrier. In particular, this refers to BOD values, which decreased even 160 times in the 1998–2016 monitoring period.
Multidisciplinary Aerodynamic Design of a Rotor Blade for an Optimum Rotor Speed Helicopter
Authors: Xie Jiayi , Xie Zhifeng , Zhou Ming , Qiu Jun
Published: June 2017

The aerodynamic design of rotor blades is challenging, and is crucial for the development of helicopter technology. Previous aerodynamic optimizations that focused only on limited design points find it difficult to balance flight performance across the entire flight envelope. This study develops a global optimum envelope (GOE) method for determining blade parameters—blade twist, taper ratio, tip sweep—for optimum rotor speed helicopters (ORS-helicopters), balancing performance improvements in hover and various freestream velocities. The GOE method implements aerodynamic blade design by a bi-level optimization, composed of a global optimization step and a secondary optimization step. Power loss as a measure of rotor performance is chosen as the objective function, referred to as direct power loss (DPL) in this study. A rotorcraft comprehensive code for trim simulation with a prescribed wake method is developed. With the application of the GOE method, a DPL reduction of as high as 16.7% can be achieved in hover, and 24% at high freestream velocity.

Published: June 2017

In order to realize high-performance thermoelectric materials, a way to obtain small grain size is necessary for intensification of the phonon scattering. Here, we use a melt-spinning-spark plasma sintering process for making p-type Bi0.36Sb1.64Te3 thermoelectric materials and evaluate the relation between the process conditions and thermoelectric performance. We vary the Cu wheel rotation speed from 1000 rpm (~13 ms−1) to 4000 rpm (~52 ms−1) during the melt spinning process to change the cooling rate, allowing us to control the characteristic size of nanostructure in melt-spun Bi0.36Sb1.64Te3 ribbons. The higher wheel rotation speed decreases the size of nanostructure, but the grain sizes of sintered pellets are inversely proportional to the nanostructure size after the same sintering condition. As a result, the ZT values of the bulks fabricated from 1000–3000 rpm melt-spun ribbons are comparable each other, while the ZT value of the bulk from the 4000 rpm melt-spun ribbons is rather lower due to reduction of grain boundary phonon scattering. In this work, we can conclude that the smaller nanostructure in the melt spinning process does not always guarantee high-performance thermoelectric bulks, and an adequate following sintering process must be included.
The Synthesis of the Core/Shell Structured Diamond/Akageneite Hybrid Particles with Enhanced Polishing Performance
Authors: Lu Jing , Xu Yongchao , Zhang Dayu , Xu Xipeng
Published: June 2017

In this study, the synthesis of the core/shell structured diamond/akageneite hybrid particles was performed through one-step isothermal hydrolyzing. The hybrid particle was characterized by X-ray diffraction, field emission scanning electron microscopy, and Fourier transform infrared spectra. The test results overall reveal that the akageneite coating, phase β-FeO(OH), was uniformly coated onto the diamond surface. The polishing performance of the pristine diamond and hybrid particles for the sapphire substrate was evaluated respectively. The experimental results show that the hybrid particles exhibited improved polishing quality and prolonged effective processing time of polishing pad compared with diamond particles without compromising the material remove rate and surface roughness. The improved polishing behavior might be attributed to the β-FeOOH coating, which is conducive to less abrasive shedding and reducing the scratch depth.

Published: June 2017

Microorganisms play an important role in weathering sulfide minerals worldwide and thrive in metal-rich and extremely acidic environments in acid mine drainage (AMD). Advanced molecular methods provide in-depth information on the microbial diversity and community dynamics in the AMD-generating environment. Although the diversity is relatively low and in general inversely correlated with the acidity, a considerable number of microbial species have been detected and described in AMD ecosystems. The acidophilic microbial communities dominated by iron/sulfur-oxidizing microbes vary widely in their composition and structure across diverse environmental gradients. Environmental conditions affect the microbial community assembly via direct and indirect interactions with microbes, resulting in an environmentally dependent biogeographic pattern. This article summarizes the latest studies to provide a better understanding of the microbial biodiversity and community assembly in AMD environments.

It is essential for the marine navigator conducting maneuvers of his ship at sea to know future positions of himself and target ships in a specific time span to effectively solve collision situations. This article presents an algorithm of ship movement trajectory prediction, which, through data fusion, takes into account measurements of the ship’s current position from a number of doubled autonomous devices. This increases the reliability and accuracy of prediction. The algorithm has been implemented in NAVDEC, a navigation decision support system and practically used on board ships.
Volatility Spillover between Water, Energy and Food
Authors: Peri Massimo , Vandone Daniela , Baldi Lucia
Published: June 2017

Water, energy, and food and are strongly interconnected, and the sustainability of the whole world depends on this link. The aim of this article is to analyze the volatility spillovers between indexes representing the financial component of this nexus. We use a multivariate Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model with daily data in which the water variable is proxy by equity index that represents the performance of the industry involved in water business both at the global and local levels. For the food and energy sectors, we use two sub-indexes of the S&P Goldman Sachs (GS)-Commodity Index. Our results highlight the existence of a financial nexus between water, energy, and food that was particularly exacerbated during 2008 crisis. Evidence therefore suggests the need to better investigate the policy options that can be used to reduce price volatility in a framework of the rising relevance of sustainability issues.

Authors: Kendrick Denise , Dhiman Paula , Kellezi Blerina , Coupland Carol , Whitehead Jessica , Beckett Kate , Christie Nicola , Sleney Judith , Barnes Jo , Joseph Stephen , Morriss Richard
Published: June 2017

Background

The benefits of work for physical, psychological, and financial wellbeing are well documented. Return to work (RTW) after unintentional injury is often delayed, and psychological morbidity may contribute to this delay. The impact of psychological morbidity on RTW after a wide range of unintentional injuries in the UK has not been adequately quantified.

Aim

To quantify the role of psychological factors, including anxiety, depression, and post-traumatic distress, on RTW following unintentional injuries.

Design and setting

A longitudinal multicentre prospective study was undertaken in Nottingham, Bristol, Leicester, and Guildford, UK.

Method

Participants (n= 273) were 16–69-year-olds admitted to hospital following unintentional injury, who were in paid employment prior to injury. They were surveyed at baseline, then at 1, 2, 4, and 12 months following injury; demographic data were collected along with injury characteristics, psychological morbidity, and RTW status. Associations between demographic, injury and psychological factors, and RTW between 2 and 12 months after injury were quantified using random effects logistic regression.

Results

The odds of RTW between 2 and 12 months after injury reduced as depression scores early in the recovery period (1 month after injury) increased (odds ratio [OR] 0.87, 95% confidence interval [CI] = 0.79 to 0.95) and as length of hospital stay increased (OR 0.91, 95% CI] = 0.86 to 0.96). For those experiencing threatening life events following injury (OR 0.27, 95% CI = 0.10 to 0.72) and with higher scores on the Crisis Support Scale (OR 0.93, 95% CI] = 0.88 to 0.99), the odds of RTW between 2 and 12 months after injury were lower. Multiple imputation analysis found similar results, but those relating to crisis support did not remain statistically significant.

Conclusion

Primary care professionals can identify patients at risk of delayed RTW who may benefit from management of psychological morbidity and support to RTW.
Inhibition of Carbonic Anhydrase IX by Ureidosulfonamide Inhibitor U104 Reduces Prostate Cancer Cell Growth, But Does Not Modulate Daunorubicin or Cisplatin Cytotoxicity
Authors: Riemann Anne , Güttler Antje , Haupt Verena , Wichmann Henri , Reime Sarah , Bache Matthias , Vordermark Dirk , Thews Oliver
Published: June 2017

Carbonic anhydrase (CA) IX has emerged as a promising target for cancer therapy. It is highly upregulated in hypoxic regions and mediates pH regulation critical for tumor cell survival as well as extracellular acidification of the tumor microenvironment, which promotes tumor aggressiveness
via various mechanisms, such as augmenting metastatic potential. Therefore, the aim of this study was to analyze the complex interdependency between CA IX and the tumor microenvironment in prostate tumor cells with regard to potential therapeutic implications. CA IX was upregulated by hypoxia
as well as acidosis in prostate cancer cells. This induction did not modulate intracellular pH but led to extracellular acidification. Pharmacological inhibition of CA IX activity by U104 (SLC-0111) resulted in a reduction in tumor cell growth and an increase in apoptotic cell death. Intracellular
pH was reduced under normoxic and even more so under hypoxic conditions when CA IX level was high. However, although intracellular pH regulation was disturbed, targeting CA IX in combination with daunorubicin or cisplatin did not intensify apoptotic tumor cell death. Hence, targeting CA IX
in prostate cancer cells can lead to intracellular pH dysregulation and, consequently, can reduce cellular growth and elevate apoptotic cell death. Attenuation of extracellular acidification by blocking CA IX might additionally impede tumor progression and metastasis. However, no beneficial effect was seen when targeting CA IX in combination with chemotherapeutic drugs.
Studying plant–pollinator interactions facing climate change and changing environments
Authors: Byers Diane L. , Chang Shu‐Mei
Published: June 2017

Plant–pollinator interactions are essential for successful plant reproduction in both natural and agricultural systems. These interactions are negatively impacted by recent large‐scale alterations of the environments, particularly climate change. The responses of plants and pollinators to changing abiotic conditions that vary seasonally and geographically are often uncoordinated, potentially leading to the breakdown of this interaction. The complexity of the responses of plants and pollinators to our changing climate necessitates creative approaches. The six articles in this special issue directly address this need by providing a variety of key methods and reviews of current methodology. The articles include: DNA barcoding methods for use on pollen collected from visiting bees; methods for assessment of plant attraction traits (nectar and review of floral volatiles methods); a field sampling method for ground nesting bees; a review of using spatial and temporal transplants for addressing changing dynamics of plant–pollinator interactions; and a review of approaches used to assess potential shifts in phenology of plants and pollinators. Collectively, these articles illustrate some of the breadth of approaches needed to address the changing dynamics of plant–pollinator interactions.
High-fidelity Simulations of the Near-Earth Object Search Performance of the Large Synoptic Survey Telescope
Authors: Vereš Peter , Chesley Steven R.
Published: June 2017

We perform high-fidelity simulations of a wide-field telescopic survey searching for Near-Earth Objects (NEOs) larger than 140 m, focusing on the observation and detection model, as well as detection efficiency and accuracy. As a test survey, we select the Large Synoptic Survey Telescope (LSST). We use its proposed pointings for a 10-year mission, and model the detection of NEOs in the fields. We discuss individual model parameters for magnitude losses, vignetting, fading, asteroid rotation and colors, fill factor, limiting magnitude, rate of motion, field shape and rotation, and survey patterns. We assess results in terms of the cumulative completeness of the detected population as a function of size and time. Additionally, we examine the sources of modeling uncertainty, and derive the overall NEO population completeness for the baseline LSST survey to be 55 ± 5% for NEOs with absolute magnitude brighter than 22. Including already discovered objects and ongoing surveys, the NEO completeness at the end of the LSST baseline survey should reach ∼77%.
Giant Planets Can Act as Stabilizing Agents on Debris Disks
Authors: Muñoz-Gutiérrez M. A. , Pichardo B. , Peimbert A.
Published: June 2017

We have explored the evolution of a cold debris disk under the gravitational influence of dwarf-planet-sized objects (DPs), both in the presence and absence of an interior giant planet. Through detailed long-term numerical simulations, we demonstrate that when the giant planet is not present, DPs can stir the eccentricities and inclinations of disk particles, in linear proportion to the total mass of the DPs; on the other hand, when the giant planet is included in the simulations, the stirring is approximately proportional to the mass squared. This creates two regimes: below a disk mass threshold (defined by the total mass of DPs), the giant planet acts as a stabilizing agent of the orbits of cometary nuclei, diminishing the effect of the scatterers; above the threshold, the giant contributes to the dispersion of the particles.

The Herbig Ae star HD 169142 is one of the objects that show complex structure, such as multiple (innermost, middle, and outer) disks, gaps, and unresolved sources. We made N-band (8–13 μm) observations of HD 169142 with the Cooled Mid-Infrared Camera and Spectrometer on the 8.2 m Subaru Telescope. The images are spatially resolved out to an ∼1″ radius in all the observed bands. We made a simple disk model composed of an unresolved central source (representing the innermost disk/halo) and the ring at a radius r ∼ 25 au (corresponding to the inner wall or edge of a middle disk at ∼25–40 au). The radial intensity profile within the central region (≲0.″3 or

au) is well reproduced by the model. Furthermore, we subtracted the model image from the observed one to search for additional structures. In the model-subtracted images, we found an unresolved west source separated by 17.0 ± 2.9 au in the direction of position angle 260° ± 5° from the original emission peak, which is supposed to correspond to the position of the central star, and a bright east arc located at r ∼ 60 au. The west source is different from the L′-band unresolved source recently found in coronagraphic observations. It could be a structure related to planet formation in the disk, such as a circumplanetary disk or clumpy disk structure. The east arc corresponds to the inner wall or edge of the outer disk.
Des « fachos » dans les rues aux « héros » sur le web
Authors: Bouron Samuel
Published: June 2017

Cet article se fonde sur une observation participante au sein du réseau Génération identitaire. Elle comprend une ethnographique du camp de formation qui porte les caractéristiques d’une institution totale. Les participants sont placés dans un jeu de rôle où ils se réinventent en défenseurs d’un territoire supposément en danger face à une menace extérieure. Ils se pensent en héros au sein d’une communauté coupée du monde extérieur. L’entre-soi sur leurs sites web et sur les réseaux sociaux les autorise alors à y prolonger leur identité militante. L’étude met ainsi en évidence l’importance de l’organisation dans la mobilisation sur Internet de ce groupe d’extrême droite.
La rumeur du PizzaGate durant la présidentielle de 2016 aux États-Unis
Authors: Rebillard Franck
Published: June 2017

Au moment de la présidentielle de 2016 aux États-Unis, une rumeur selon laquelle le directeur de campagne d’Hillary Clinton aurait organisé un trafic sexuel d’enfants, dans une pizzeria de Washington, a été colportée sur Internet. Cette rumeur dite du PizzaGate a pris appui sur plusieurs types de documents accessibles en ligne, diversement réinterprétés et réexploités : e-mails de responsables du Parti démocrate exhumés sur Wikileaks, photographies du propriétaire du restaurant piochées sur son compte Instagram, avis de recherche de Scotland Yard lié à un logiciel de reconstitution faciale. Leur analyse permet d’illustrer une composante de la médiatisation du politique en ligne souvent négligée, sa composante documentaire, susceptible de renforcer les discours conspirationnistes et l’agitation politique de façon plus générale.
Crise économique et différenciation territoriale. Les régions et les métropoles dans la décentralisation française
Authors: Pasquier Romain
Published: June 2017

La crise économique a-t-elle recentralisée la décentralisation? L’hypothèse avancée ici est celle d’une poussée des dynamiques de métropolisation et de régionalisation en France sous la conjugaison de processus de convergence commun à l’ensemble de l’Union européenne (UE). Cependant, ces processus de convergence empruntent des sentiers institutionnels et politique distincts selon les régions dessinant une forte différenciation des configurations territoriales. En Bretagne, le modèle régional semble s’imposer progressivement. En Île-de-France, une métropolisation puissante est en voie d’institutionnalisation à l’initiative de l’État tandis qu’en Rhône-Alpes, le fait métropolitain semble concurrencer sinon supplanter une régionalisation à la croisée des chemins.
Devolution in Wales: Between Economic Constraint and Political Opportunity
Authors: Stafford Ian
Published: June 2017

L’expérience britannique, et en particulier le cas du Pays de Galles, soulève des doutes quant à un effet « mécanique » de recentralisation induit par la crise économique. À partir d’une série d’entretiens avec 26 personnes-clefs interrogées entre octobre 2012 et juillet 2013 (représentant trois groupes d’acteurs importants, à savoir l’administration décentralisée, les groupes d’intérêt professionnels et les réseaux d’action publique locale, les représentants élus au niveau régional), le papier analyse la question de la décentralisation au Pays de Galles en relation avec les thèmes-clés identifiés dans l’avant-propos : l’expérience de discipline budgétaire en lien avec la crise ; l’impact de l’Union européenne ; la restructuration de l’État et les défis majeurs identifiés par les décideurs régionaux. Le positionnement du Royaume-Uni en dehors de la Zone Euro signifie que le Pays de Galles n’a pas été soumis aux pressions de la convergence « dure », laquelle a imposé de plus en plus de contraintes aux acteurs du niveau subétatique à travers l’Europe. Bien que le Pays de Galles ait fait face à des contraintes économiques et des pressions fiscales accrues, et similaires à la convergence « dure », en raison du programme d’austérité du Gouvernement britannique, il a pu préserver ses services publics locaux à court terme. En outre, la crise économique a agi comme un catalyseur pour ouvrir des fenêtres d’opportunité en vue de développer la décentralisation et favoriser la réforme des services publics. Les décideurs gallois ont essayé de faire un bon usage de la crise et de démontrer que le gouvernement décentralisé était capable de gérer le changement.

Applying Artificial Intelligence to Financial Investing
Authors: Wimmer Hayden , Rada Roy
Published: June 2017

Artificial intelligence techniques have long been applied to financial investing scenarios to determine market inefficiencies, criteria for credit scoring, and bankruptcy prediction, to name a few. While there are many subfields to artificial intelligence this work seeks to identify the most commonly applied AI techniques to financial investing as appears in academic literature. AI techniques, such as knowledge-based, machine learning, and natural language processing, are integrated into systems that simultaneously address data identification, asset valuation, and risk management. Future trends will continue to integrate hybrid artificial intelligence techniques into financial investing, portfolio optimization, and risk management. The remainder of this article summarizes key contributions of applying AI to financial investing as appears in the academic literature.

This chapter seeks to define the various fields that comprise artificial intelligence and look at the history of AI and suggest future research directions.
Automatic Emotion Recognition Based on Non-Contact Gaits Information
Authors: Wang Jingying , Li Baobin , Zhu Changye , Li Shun , Zhu Tingshao
Published: June 2017

Automatic emotion recognition was of great value in many applications, however, to fully display the application value of emotion recognition, more portable, non-intrusive, inexpensive technologies need to be developed. Except face expression and voices, human gaits could reflect the walker's emotional state too. By utilizing 59 participants' gaits data with emotion labels, we train machine learning models that are able to “sense” individual emotion. Experimental results show these models work very well, proved that gait features are effective in characterizing and recognizing emotions.

Architecture as a Tool to Solve Business Planning Problems
Authors: McKee James
Published: June 2017

Businesses are now very large and complex organisations and their analysis provides a great deal of information that in order to be understood, must be well organised and presented. Architecture is a scheme that allows a systematic examination of the entire enterprise and can provide a well-organised presentation of the key components, their interdependencies and the important causal relations. This paper discusses the problems associated with developing an architecture and suggests a framework for developing a reference model to guide the definition of the business architecture.
Social Issues in IT Project Teams
Authors: Leonard Awie C. , Van Zyl D. H.
Published: June 2017

The role and impact of social issues in IT project teams should not be under estimated. With the involvement of virtual project teams, this is even more relevant. One such social issue is the establishment of relationships between members of teams. The establishment and maintenance of social relationships and networks in the IT project environment is a phenomenon all IT professionals are exposed to and in many cases involved in. The question is what impact such social relationships and networks might have on the success or failure of any given IT project? The objective of this chapter is therefore to emphasize the important role social relationships and networks play in the IT project team environment. Furthermore, to illustrate to the management of software project teams how such relationships can have a positive or negative impact on team members. In this regard a climate or culture should be allowed for these relationships to flourish to the benefit of the IT department.
