Empowerment of Women in The Informal Sector to Increase Household Income : Case Study in Sleman
Authors: Susianti Susianti
Published: June 2019

This study aims to identify and analyze women's empowerment in the informal sector. The involvement of women in earning a living shows the role of women increasingly evident in economic allocation. This is an opportunity for women to carry out production activities in the midst of economic conditions that are less supportive for subsistence economic groups. Various types of informal economic activities are carried out by women while considering the allocation of time for families and routine household work. One of the informal economic activities that many women do is a household stall business. Problems that are still found in the household stall business are related to its market share which has limited demand. In this case, turnover of stalls also depends on the increase in consumption or the amount that can be spent by the surrounding community. Without an increase in the income of the business community, it is difficult to expect an increase in purchasing power and consumption levels even though this household stall is one source of women's income to help sustain household life. This research is quantitative with a purposive sampling method for sampling. The research was conducted in Sleman, DI Yogyakarta. From the multiple linear regression analysis with the OLS method used shows that from the variables of capital, education, age and working hours of women working in the informal sector in Sleman, the variables of work capital and education have positive and significant coefficients. Meanwhile, the results of descriptive analysis show that the main reasons and motivations that encourage women to work in the informal sector in Sleman, DI. Yogyakarta are to increase household income to meet their needs.

FATORES DE RISCO E ASPECTOS FISIOPATOLÓGICOS ENVOLVIDOS NA NEFROPATIA DA HANSENÍASE: UMA REVISÃO INTEGRATIVA
Authors: Holanda Dias Joice , Lins Braga Kassandra , Lívia Fonseca Moreira de Medeiros Renata
Published: June 2019

Objetivo: analisar na literatura científica as possíveis causas do acometimento renal na Hanseníase, partindo da seguinte questão norteadora: quais os principais fatores de risco e seus respectivos papéis na fisiopatologia da nefropatia da hanseníase? Método: trata-se de uma revisão integrativa da literatura realizada no ano de 2018. Para a sua produção, foram consultadas as bases de dados: Biblioteca Virtual em Saúde (BVS), Publicações Médicas (PubMed), Medline e biblioteca virtual Scientific Eletronic Library online (SCIELO), assim como foram empregados operadores booleanos e os Descritores em Ciência da Saúde (DECS): hanseníase, nefropatia, doença, rim e glomerulonefrite, em diferentes combinações. Resultados: a busca foi conduzida nas bases de dados selecionadas, com a pesquisa do descritor Hanseníase, isoladamente, e depois associado aos demais descritores. Em seguida, foram aplicados os filtros conforme os critérios de inclusão, sendo encontrados 42 artigos. Após exclusão das repetições e leitura dos resumos, foi possível identificar 5 estudos que convergiam para responder a questão norteadora levantada inicialmente. A análise dos artigos demonstra uma predominância de relatos de caso sobre pacientes com hanseníase que apresentaram rápido declínio da função renal. Tais casos são considerados raros na medicina, fato que pode ser explicado pela dificuldade em reconhecer os fatores de risco e obter o diagnóstico. Conclusões: Pacientes com hanseníase e fatores predisponentes para injúria renal, devem ter a função renal avaliada precocemente para diagnosticar lesões do parênquima. Como as manifestações clínicas costumam aparecer tardiamente, é preciso lançar mão de parâmetros laboratoriais sensíveis, e conforme mais estudos forem publicados a respeito da proteína quimiotática de monócitos urinários tipo 1 (MCP-1), esse biomarcador poderá contribuir para o diagnóstico e intervenção terapêutica no momento oportuno, evitando a perda da função renal do paciente.

The phytogenic effect of different-aged black saxaul plants on the productivity of wormwood-ephemeral vegetation under the conditions of Karnabchul
Authors: SHavkat Rashidovich Ubaydullayev , Farmon Murtozevich Mamatov
Published: June 2019

The aim of the study is to determine the effect of different-age black saxaul plants on the productivity of wormwood-ephemeral vegetation through the study of the phytogenic field of this ephemeroid species. The phytogenic field of black saxaul has been studied by the phytomer method in the desert Karnabchul. The study showed that its influence in the minimum phytogenic field on the productivity of wormwood-ephemeral vegetation is negative, in the external part of the phytogenic field on bluegrass and forbs is positive, and on wormwood and sedge remains negative. The highest productivity indices are observed in them between the outer and inner and outer parts of the phytogenic field of the middle-aged generative plants of the edificator.
Statistical Analysis of Interplanetary Magnetic Field Path Lengths from Solar Energetic Electron Events Observed by WIND
Authors: Zhao Lulu , Li Gang , Zhang Ming , Wang Linghua , Moradi Ashraf , Effenberger Frederic
Published: June 2019

We calculate the interplanetary magnetic field path lengths traveled by electrons in solar electron events detected by the WIND 3DP instrument from 1994 to 2016. The velocity dispersion analysis method is applied for electrons at energies of ∼27–310 keV. Previous velocity dispersion analyses employ the onset times, which are often affected by instrumental effects and the pre-existing background flux, leading to large uncertainties. We propose a new method here. Instead of using the peak or onset time, we apply the velocity dispersion analysis to the times that correspond to the rising phase of the fluxes that are a fraction, η, of the peak flux. We perform statistical analysis on selected events whose calculated path lengths have uncertainties smaller than 0.1 au. The mean and standard deviation, (μ, σ), of the calculated path lengths corresponding to η = 3/4, 1/2, and 1/3 of the peak flux is (1.17 au, 0.17 au), (1.11 au, 0.14 au), and (1.06 au, 0.15 au). The distribution of the calculated path lengths is also well fitted by a Gaussian distribution for the η = 3/4 and 1/3 cases. These results suggest that in these electron events the interplanetary magnetic field topology is close to the nominal Parker spiral, with little field line meandering. Our results have important implications for particles’ perpendicular diffusion.
Effects of Coronal Density and Magnetic Field Distributions on a Global Solar EUV Wave

Published: June 2019

We investigate a global extreme-ultraviolet (EUV) wave associated with a coronal mass ejection (CME)-driven shock on 2017 September 10. The EUV wave is transmitted by north- and south-polar coronal holes (CHs), which is observed by the Solar Dynamics Observatory (SDO) and Solar Terrestrial Relations Observatory A (STEREO-A) from opposite sides of the Sun. We obtain key findings on how the EUV wave interacts with multiple coronal structures, and its connection with the CME-driven shock: (1) the transmitted EUV wave is still connected with the shock that is incurvated to the Sun, after the shock has reached the opposite side of the eruption; (2) the south CH transmitted EUV wave is accelerated inside an on-disk, low-density region with closed magnetic fields, which implies that an EUV wave can be accelerated in both open and closed magnetic field regions; (3) part of the primary EUV wavefront turns around a bright point (BP) with a bipolar magnetic structure when it approaches a dim, low-density filament channel near the BP; (4) the primary EUV wave is diffused and apparently halted near the boundaries of remote active regions (ARs) that are far from the eruption, and no obvious AR related secondary waves are detected; (5) the EUV wave extends to an unprecedented scale of ∼360° in latitudes, which is attributed to the polar CH transmission. These results provide insights into the effects of coronal density and magnetic field distributions on the evolution of an EUV wave, and into the connection between the EUV wave and the associated CME-driven shock.
GeV Observations of the Extended Pulsar Wind Nebulae Constrain the Pulsar Interpretations of the Cosmic-Ray Positron Excess
Authors: Xi Shao-Qiang , Liu Ruo-Yu , Huang Zhi-Qiu , Fang Kun , Wang Xiang-Yu
Published: June 2019

It has long been suggested that nearby pulsars within ∼1 kpc are the leading candidate of the 10–500 GeV cosmic-ray positron excess measured by PAMELA and other experiments. The recent measurement of the surface brightness profile of TeV nebulae surrounding Geminga and PSR B0656+14 by the High-Altitude Water Cherenkov Observatory (HAWC) suggests inefficient diffusion of particles from the sources, giving rise to a debate on the pulsar interpretation of the cosmic-ray positron excess. Here we argue that GeV observations provide more direct constraints on the positron density in the TeV nebulae in the energy range of 10–500 GeV and hence on the origin of the observed positron excess. Motivated by this, we search for GeV emission from the TeV nebulae with the Fermi Large Area Telescope (LAT). No spatially extended GeV emission is detected from these two TeV nebulae in the framework of two-zone diffusion spatial templates, suggesting a relatively low density of GeV electrons/positrons in the TeV nebulae. A joint modeling of the data from HAWC and Fermi-LAT disfavors Geminga and PSR B0656+14 as the dominant sources of the positron excess at ∼50–500 GeV for the usual Kolmogorov-type diffusion, while for an energy-independent diffusion, a dominant part of the positron excess contributed by them cannot be ruled out by the current data.
Modeling the Protoplanetary Disks of Two Brown Dwarfs in the Taurus Molecular Cloud

Published: June 2019

Measuring the properties of protoplanetary disks around brown dwarfs (BDs) is central to understanding the formation of BDs and their planetary companions. We present modeling of CFHT Tau 4 and 2M0444, two BDs with protoplanetary disks in the Taurus Molecular Cloud. By combining modeling of the spectral energy distributions and Atacama Large Millimeter/submillimeter Array images, we obtain disk radii and masses for these objects; these parameters can be used to constrain BD formation and planet formation, respectively. We find that the disk around CFHT Tau 4 has a total mass of 0.42 M
Jup and a radius of 80 au; we find 2M0444's disk to have a mass of 2.05 M
Jup and a radius of 100 au. These radii are more consistent with those predicted by theoretical simulations of BD formation via undisturbed condensation from a mass reservoir than with those predicted by ejection from the formation region. Furthermore, the disk mass of 2M0444 suggests that planet formation may be possible in this disk, although the disk of CFHT Tau 4 is likely not massive enough to form planets. The disk properties measured here provide constraints to theoretical models of BD formation and the formation of their planetary companions.

Published: June 2019

Nanotechnology has been widely exploited in recent years in various applications. Different sectors of medicine and treatment have also focused on the use of nanoproducts. One of the areas of interest in the treatment measures is the interaction between nanomaterials and immune system components. Engineered nanomaterials can stimulate the inhibition or enhancement of immune responses and prevent the detection ability of the immune system. Changes in immune function, in addition to the benefits, may also lead to some damage. Therefore, adequate assessment of the novel nanomaterials seems to be necessary before practical use in treatment. However, there is little information on the toxicological and biological effects of nanomaterials, especially on the potential ways of contacting and handling nanomaterials in the body and the body response to these materials. Extensive variation and different properties of nanomaterials have made it much more difficult to access their toxicological effects to the present. The present study aims to raise knowledge about the potential benefits and risks of using the nanomaterials on the immune system to design and safely employ these compounds in therapeutic purposes.

Published: June 2019

BACKGROUND: Thrombus aspiration for ST-segment elevation myocardial infarction (STEMI) may improve myocardial perfusion. However, these favourable results called into a question by data indicating not only a lack of efficacy but a risk of potentially deleterious complications.AIM: To assess the effect of thrombus aspiration during the primary percutaneous coronary intervention (PPCI) on procedural angiographic results, stent characteristics, and major adverse cardiac and cerebrovascular events (MACCE).METHODS: All consecutive STEMI patients candidate for PPCI and admitted to Critical Care Department, Cairo University hospitals, managed either by thrombectomy before primary PCI (if thrombus score ≥ 3) or conventional PPCI, Six hundred seven subjects were enrolled in the study divided into Group with thrombectomy before PPCI (107 subjects, 18%), and group with Conventional PCI (500 subjects, 82%). ST-segment resolution, peak CK-MB, TIMI score, thrombus score, and MBG were assessed; stent number, diameter, length and stented segment were reported and follow up MACCE was reported (in hospital and 1-year post-intervention).RESULTS: Mean values for peak CKMB were less in thrombectomy group (228 ± 174 I/U vs 269 ± 186 I/U, p = 0.04), ST segment resolution ≥ 70% occurred in {63 subjects (58.9%) vs 233 (46.6%), p = 0.001} in thrombectomy vs conventional group respectively. TIMI score pre procedure was zero in (102 subjects (95%) vs 402 (80.4%), p = 0.001), while TIMI III post procedure was reported in (100 subjects (93.4%) vs 437 (87%), p = 0.06), MBG mean values were (2.4 ± 0.6 vs 2.0 ± 1, p = 0.001), thrombus score was higher in thrombectomy group (4.6 ± 0.4 vs 0.8 ± 1.7, p = 0.001) in thrombectomy vs conventional group respectively .Direct stenting was { 34 patients (31%) vs 102 patients (20%), p = 0.05} , mean stent diameter (2.7 ± 1.3 mm vs 3.5 ± 1.3 mm, p = 0.3), mean stent length was (19.9 mm ± 10 versus 22.7 mm ± 8 in p 0.01). mean stent number was (1.0 ± 0.5 vs 1.2 ± 0.6, p = 0.001), mean stented segment was (22.5 ± 13.5 vs 28.5 ± 15.2 mm, p = 0.001) in thrombectomy vs conventional group respectively. MACCE in hospital were reported in {9 subjects (8.4%) vs 70 (14%), p = 0.07)}. Follow up MACCE after 1 year reported in {6 subjects (5.6 %) vs 80 (16 %), p 0.= 4} in thrombectomy vs conventional group respectively.CONCLUSION: Thrombus aspiration before primary PCI (in a selected group with thrombus score ≥ 3) improves myocardial perfusion, suggested by better ST-segment resolution, TIMI flow, less peak CKMB and MBG, associated with a higher rate of direct stenting, shorter stent length, stented segments and less number of stents. Although thrombus aspiration was done in more risky patients (higher thrombus score) MACCE (in hospital and 1 year follow up) showed no statistical difference.
A citation-based map of concepts in invasion biology
Authors: Enders Martin , Havemann Frank , Jeschke Jonathan M.
Published: June 2019

Invasion biology has been quickly expanding in the last decades so that it is now metaphorically flooded with publications, concepts, and hypotheses. Among experts, there is no clear consensus about the relationships between invasion concepts, and almost no one seems to have a good overview of the literature anymore. Similar observations can be made for other research fields. Science needs new navigation tools so that researchers within and outside of a research field as well as science journalists, students, teachers, practitioners, policy-makers, and others interested in the field can more easily understand its key ideas. Such navigation tools could, for example, be maps of the major concepts and hypotheses of a research field. Applying a bibliometric method, we created such maps for invasion biology. We analysed research papers of the last two decades citing at least two of 35 common invasion hypotheses. Co-citation analysis yields four distinct clusters of hypotheses. These clusters can describe the main directions in invasion biology and explain basic driving forces behind biological invasions. The method we outline here for invasion biology can be easily applied for other research fields.
Ontologies and databases on thermophysical properties of nuclear reactor materials
Authors: Chusov Igor A. , Kirillov Pavel L. , Pronyaev Vladimir G. , Obysov Nikolay A. , Novikov Grigoriy E.
Published: June 2019

The study is dedicated to the information technologies for storage, systematization and distribution of thermophysical data for nuclear power engineering. The general trend existing in the areas involving wide use of scientific data is the shifting from conventional databases to the development of a consolidated infrastructure capable of overcoming sharply growing volumes of scientific data with continuously increasing complexity of the data structure due to the expansion of the range of materials. The above infrastructure ensures interoperability, including data exchange and dissemination. The general principle of data management for thermophysical properties of the nuclear reactor materials based on the subject-oriented ReactorThermoOntology (RTO) is suggested in the present paper. The ontology includes a unified glossary of all concepts, expanded through logical connections and axioms. The suggested RTO ontology combines the terms typical for reactor materials, their characteristics, as well as all types of information entities determining textual, mathematical and computer structures. In the coded form, the ontology becomes the control add-in capable to integrate heterogeneous data. Its most important feature is the possibility of its permanent expansion, which is necessary with introduction of new materials and terms related to them, e.g. nanostructures characteristics. Beside the ontology, description of the reactor materials, the possible scenarios for the use of the ontology during the phases of design, operation and integration of autonomous resources, primarily databases, are examined in the paper. The use of Big Data technology with diverse variations of logical structures of the data is suggested as the most efficient tool for data integration. Joint use of the technologies which before were applied separately, such as exchange standard in the form of the structured text documents, data control based on the ontology and platform for the work with big data, allows the conversion of multiple existing primary resources (databases, files, archives, etc.) to the standard JSON text format for the subsequent semantic integration.
Use of mathematical modeling to extend the scope of application for the procedure of measuring the mass of 235U in solid radioactive waste
Authors: Rykov Nikita S. , Bezhunov Gennady M. , Gorbachev Vyacheslav M.
Published: June 2019

The known dependence of absolute efficiency on energy and space for particular measurement conditions is used to determine the mass (activity) of 235U in solid radioactive waste by gamma-spectrometric method. The ISOCS system makes it possible to avoid laborious and time-consuming calibration measurements using standard samples to obtain the absolute efficiency curve due to using the so-called characterized detector having a file with a set of efficiencies for various measurement geometries.

In many cases, the establishment of standard samples with parameters covering the 235U mass measurement range in the variation intervals of influencing factors, including density, non-uniformity, isotopic composition, geometry, etc., is very expensive and, most often, not feasible. With regard for this, a computational and experimental approach is used based on results obtained by Monte Carlo method using the MCNP code with variation of the key influencing parameters in a broad range.

Calculations were performed for detector-recorded spectra of gamma quanta from casks containing waste differing in the density of the cask content (the density was calculated with regard for the uranium contained in waste) – from 0.016 to 1 g/cm3, in the mass of uranium in waste – from 0.64 g to 2 kg, and in the matrix material – graphite, cellulose, quartz, cellulose with 20 % of iron dust.

Applicability boundaries have been defined for the developed procedure to measure uranium-containing waste in terms of the material matrix (~ 2.2 %) and its density (~ 10 %) and the contribution of the uranium mass uncertainty in the cask (5 % for nonporous matrices, 10 % for porous matrices) to the obtained result has been estimated.
Villes espagnoles et austérité : une histoire de longue durée
Authors: Vaz Céline
Published: June 2019

Cet article vise à interroger la nouveauté de l’« urbanisme d’austérité » dans le cas des pays d’Europe du Sud et, précisément, de l’Espagne, en replaçant cette notion dans l’histoire plus globale et de plus long terme de l’État social et de l’autonomie des gouvernements locaux espagnols. Il s’agit aussi de montrer que la privatisation croissante de la production des espaces urbains et de la gestion urbaine, mise en relation dans les analyses récentes avec la réduction des dépenses publiques, n’est pas un phénomène neuf en Espagne. Le rôle des acteurs de marché dans la production de la ville, présenté comme un élément saillant des politiques d’austérité actuelles, caractérise la situation de l’Espagne durant la dictature franquiste (1939-1975).
Plateformes locatives en ligne et rente urbaine à Turin : les classes moyennes face à l’austérité
Authors: Semi Giovanni , Tonetta Marta
Published: June 2019

Le secteur du logement constitue une entrée pertinente pour comprendre le contexte actuel de diffusion de l’austérité. C’est particulièrement vrai pour les pays du sud de l’Europe et notamment l’Italie, qui conservent des caractéristiques spécifiques en matière de logement et de welfare. Cet article explore les nouveaux usages de la propriété qui se développent pour faire face à l’austérité, et notamment la diffusion des locations de courte durée sur les plateformes en ligne (Airbnb et similaires). Après un cadrage sur les spécificités de la ville de Turin, notre cas d’étude, on se focalisera sur le quartier populaire de Aurora, au Nord du centre-ville, et sur la géographie locale des locations temporaires. Il s’agira d’étudier les diverses formes de rente urbaine qui s’élaborent dans les pratiques quotidiennes en contexte d’austérité, en particulier au sein des classes moyennes. L’analyse des entretiens permet d’interpréter ces comportements comme des stratégies de contournement du quotidien de la crise. La conclusion porte sur les implications à long terme de ces pratiques, en particulier pour ce qui concerne la structure urbaine et la reproduction des inégalités sociales, tout en suggérant de nouvelles pistes de recherche.
Que reste-t-il du barrio dans une métropole contemporaine ? Habiter et s’approprier deux quartiers de Buenos Aires en mutation, Villa Urquiza et Villa del Parque
Authors: Martinet Gilles
Published: June 2019

Villa Urquiza et Villa del Parque, barrios (quartiers) du péricentre de la ville de Buenos Aires lotis au mitan du vingtième siècle, sont des espaces résidentiels occupés principalement par les classes moyennes. Comme beaucoup d’autres barrios, ils furent longtemps caractérisés par leur vie sociale et économique locale, ainsi que par leur morphologie où prédominaient de façon quasi absolue les maisons individuelles. Depuis le milieu des années 2000, ces espaces connaissent une intense activité immobilière, qui a modifié radicalement leur physionomie, par la généralisation des immeubles d’habitation dans plusieurs zones. Les évolutions architecturales de ces espaces sont intimement liées aux mutations de la production de la ville, comme aux pratiques et représentations des leurs habitant.e.s. Les mobilités quotidiennes dans la métropole se font plus nombreuses et sinueuses, participant à l’émergence d’archipels de lieux – structurés par les pratiques différenciées des habitant.e.s – qui bouleversent la façon d'habiter le barrio et la ville. Plus profondément encore, ce sont les modalités d'appropriation du quartier qui se sont radicalement transformées : des pratiques aux représentations, les habitant.e.s semblent n'avoir plus véritablement prise sur la production des espaces où elles et ils résident.
Opérations de contextualisation et écriture de l’histoire littéraire : l’exemple de quelques écrits du XVII e siècle
Authors: Giavarini Laurence
Published: June 2019

Dans cet article, on pose que la désignation d’un écrit comme littéraire est une opération de classement dans la littérature, un geste de contextualisation déterminé par les fins et les objectifs propres de l’histoire littéraire. Ce type de contextualisation a priori empêche de saisir les actions par lesquelles les écrits ont été situés en leur temps ou plus tard, dans la littérature. Penser l’historicité de la littérature, ce ne peut être à l’inverse qu’historiciser les gestes de contextualisation ou d’autocontextualisation qui ont permis de recevoir des écrits comme « littéraires ». Quelques exemples d’écrits du xvii e  siècle, canonisés ou non, permettent d’examiner quelques aspects du problème de méthode ainsi posé.

A survey of trainers on the use of swimming and other water-based exercise for Thoroughbred racehorses in Australia
Authors: Steel C. , Morrice-West A.
Published: June 2019

We aimed to determine the extent of use of water-based exercise and to describe swimming training practices in Thoroughbred racehorses in Victoria, Australia. A convenience sample of 118 trainers were interviewed, information relating to swimming protocols, perceived benefits and contra-indications, and use of other water-based exercise recorded and descriptive data analyses performed. Water-based exercise was used by 85.6% (n=101) trainers: 82.2% (n=97) swimming, 25.4% (n=30) using a water walker, 13.6% (n=16) incorporating ridden trotting (‘surging’) exercise in chest deep water, and 1.7% (n=2) using an underwater treadmill. Common reasons (and trainer %) for swimming were training variety and mental ‘freshness’ (62.9%), part of the exercise regime on ‘slow’ days (61.9%) and fitness benefits (60.8%). These horses swam a median of 50-90 m (ranging from a minimum of 40-180 m to a maximum of 40-450 m), continuously or as intervals, after track work, once or twice daily a median 3 days/week (range 0.5-7). Swimming for 50 (range 40-120 m) to 90 m (range 40-200 m) before track work 7 days/week (range 3-7) was used by 43 of the 97 trainers (44.3%) to manage horses prone to exertional rhabdomyolysis. Swimming was used to replace fast work by three trainers who swam horses with limb injuries up to 270-450 m. Common reasons (and % trainers) for not swimming individual horses were demeanour/distress (73.2%), previous swim colic (35.1%) or exercise induced pulmonary haemorrhage (35.1%) although only five trainers had ever seen epistaxis after swimming exercise. Swimming is widely used in training Thoroughbred horses in Australia yet trainer opinions particularly on fitness benefits, contra-indications and protocols vary widely and need to be scientifically validated. Diversifying training activities is a common strategy for managing racehorses in training, yet a better understanding of the best use of swimming and other cross-training options is needed so that evidence-based recommendations can be made.
Motivations for choosing brick-and-mortar stores between urban commerce and shopping centers: the case of Logroño retail

Published: June 2019

The aim of this work is to identify the reasons behind the choice of brick-and-mortar stores to make purchases and provide new evidence of the role that such establishments play in the omnichannel environment. An empirical study carried out in the city of Logroño (Spain) shows that utilitarian and hedonic motives are intertwined and differ according to age. Young people opt for shopping centers and the range of products and services they have to offer. Adults and elderly customers associate personal attention with shops located in the city center. The fundamental conclusion of the present work is that the establishments located in shopping centers and urban centers can coexist, each developing their own strengths. Both types of establishments provide interesting benefits for consumers who, in certain situations, opt for brick-and-mortar stores and value the offline shopping experience.
The relationship between SCM and business strategy. A Delphi study in Latin America
Authors: Arredondo Carlos Raúl , Alfaro Tanco José Antonio
Published: June 2019

The aim of this research is to identify the factors that influence the implementation of supply chain management (SCM) strategy in Latin America countries. More specifically, we focus on the study of the degree of SCM strategy involvement into the design of business strategy through the analysis of the following aspects: organization culture, incentive programs for managers, internal alignment, and segmentation. These aspects are evaluated at a firm level of analysis in order to understand how the internal organization gives way to a correct SCM implementation. The authors use a Delphi Methodology on a panel of 13 Latin American experts in SCM and logistics in order to validate a set of SCM constructs that represent different aspects of integration and that should be presented as SCM strategy aspects in the definition of the business strategy of the firm. As a result, the differences in the experts’ opinions regarding the proposed constructs clearly indicate that even the constructs have to be included into the SCM strategy, there is still much to be defined in terms of SCM strategy and how SCM participates in the Business Strategy and, thus clear guidelines must be proposed to enable its proper operationalization. To deepen the phenomenon of SCM as a fundamental part of the strategy of the company and thus analyze in detail the conditions that must be taken within the organization for its further operationalization are a still pending innovative approach in the matter. This study permits to develop a useful framework as a guide to involve SCM strategy into business strategy.

Published: June 2019

This research analyzes the influence of robotics on tourism. It is an innovative phenomenon, but one that is expected to be present in most tourism and communication activities. Robotics is beginning to produce results in terms of jobs related to tourism. Robots are incorporated in all types of establishments, especially in hotels, restaurants and museums. The phenomenon is analyzed through a quantitative (implementing data from automatic check-in and check-out machines in Barcelona hotels) and qualitative (in-depth interviews) methodology. The improvements and drawbacks that they can represent are observed, as well as their repercussion on the tourism work environment. It is concluded that the inclusion of robotics in tourism is still in the development phase, but it implies personnel savings and more personalized and interactive attention for the end user. The machines are used more often in hostels and tourist apartments than in hotels.
Teaching as coaching: Experiences with a video-baed flipped classroom combined with project-based approach in technology and physics higher education
Authors: Torio Herena
Published: June 2019

The role of faculty in higher education as knowledge disseminators within the knowledge and digital society can be completely redefined. This paper presents results from a video-based flipped classroom approach combined with a project-oriented learning arrangement. I show that videos combined with a project-based learning setting can be a powerful tool to facilitate the shift from knowledge dissemination to knowledge appropriation. Besides, results show a high level of student's satisfaction and achievement during the course. The competences obtained by the students during the course reach far beyond those possible in a similar course with a traditional teaching approach.
Effect of Core Self-Evaluation on Mental Health Symptoms Among Chinese College Students: The Mediating Roles of Benign and Malicious Envy
Authors: Xiang Yanhui , Zhao Jiaxu , Li Qingyin , Zhang Wenrui , Dong Xia , Zhao Jingjing
Published: June 2019

Core self-evaluation is a universal personality trait. Previous studies have shown that there is a negative correlation between core self-evaluations and mental health symptoms. However, core self-evaluation is also a key variable for eliciting different kinds of envy, and envy has a close relationship with mental health symptoms. At present, little is known about how different kinds of envy affect the relationship between core self-evaluation and mental health symptoms. This study used malicious and benign envy as mediating variables and explored their mediating roles between core self-evaluation and mental health symptoms. We recruited 811 Chinese college students to complete the Core Self-Evaluation Scale, Benign and Malicious Envy Scale, and Symptom Checklist 90 Scale. The results showed that there was a negative correlation between core self-evaluation and mental health symptoms, and malicious and benign envy played roles in mediating it. Because malicious envy and benign envy positively predicted mental health symptoms, and core self-evaluations inhibited mental health symptoms by preventing these two kinds of envy. Moreover, the mediating effect of malicious envy was stronger than that of benign envy.

Published: June 2019

Suicide is a leading cause of death in many nations around the world. Despite increased awareness of depression and suicidality in adolescents, specific groups continue to be affected by this growing health problem. In this article, the authors review literature and statistics surrounding suicide in adolescents and young adults. Specifically, we examine the epidemiology of suicide in adolescents; highlight protective and risk factors and warning signs of adolescent suicide; explore the roles of technology, prevention programming, and screening tools for youth who are at risk; and discuss treatment modalities for this patient population.

O 'retrato' do hospital da Misericórdia de Vila Viçosa (Portugal) em 1870
Authors: Lobo de Araújo Maria Marta
Published: June 2019

[pt] O nosso estudo analisa o hospital da Misericórdia de Vila Viçosa em 1870 com base na descrição elaborada pelo administrador do concelho nessa data. Os elementos fornecidos procuram conhecer a instituição a que está ligado –a Misericórdia–, e contribuir para uma melhor administração.
Com base nesta fonte é possível conhecer o hospital, bem como a política seguida pela confraria no tocante à saúde. O seu estudo dá a conhecer o funcionamento da instituição, desde os seus espaços aos doentes, apresentando um hospital Municipal de traça quinhentista, embora adaptado às necessidades do século XIX.
Integra ainda as sugestões do administrador do concelho, embora estas não sejam implementadas devido à escassez de receitas com que o hospital se debatia, as quais eram as responsáveis pelo estado de degradação em que alguns dos seus espaços se encontravam, mas sobretudo pelo corte no internamento de doentes e da assistência aos que se curavam em suas casas.
Structure, Microsctructure and Magnetic Properties of Ternary (Fe0.6Al0.4)100-xSix Nanostructured Powders: Effect of Si Addition

Published: June 2019

Nanostructured (Fe0.6Al0.4)100-xSix powders with x= 0, 5, 10, 15 and 20 at.% were elaborated by means of mechanical alloying for a fixed milling time of 72 h. We have investigated the effect of silicon addition on the microstructure and magnetic properties of these ternary alloys. X-ray diffraction experiments reveal that these powders are single-phase disordered solid solutions with body centered cubic crystal structure. The lattice parameter diminishesalmost linearly as the Si content increases. The mean crystallite size,, is around three times smaller for the samples with higher amount of Si (≈ 10 nm) compared with that of the binary alloy (27 nm). Moreover, the volume fraction of grain boundaries (fgb) seems to be higher with increasing the Si content, as well as both dislocation density (ρ) and lattice microstrain (<ε>),that follow alinear trend. The SEM images show that the Si helps in refining the shape and size of the powder particles, leading to a nearly homogeneous small particles.The addition of Si strongly affects the value of the saturation magnetization, Ms, that falls nearly an order of magnitude for the sample with 20 at.% Si, while the coercivity remains almost unchanged. The Mössbauer spectra show the presence of a sextet (ferromagnetic phase) and a singlet or a doublet (non ferromagnetic phase), except for the sample corresponding to x = 10, where only one singlet is observed in the spectrum.
Conductivity of Porous Phosphate-Silicate Glass Synthesized with Non-Ionic Surfactant
Authors: Zhang Xiao Ting , Zhang Fei Peng , Wang Xiao , Yang Liu Shuan
Published: June 2019

Porous, phosphate-silicate glass with high-conductivity and nano-size pores was synthesized through a xero-gel route, using non-ionic surfactant polyethylene glycol monocetyl ether (Brij 56) to control pore size. The influences of Brij 56 concentration on pore size and conductivity under different humidity were studied by measuring conductivity and calculating the volume ratio of adsorbed-water to pore volume. Samples prepared with 0.1 wt% Brij 56 had 5.2 nm pore size, 0.91 volume ratio, and narrower pore size distribution than other samples. The nano-size pores were filled with water, which in pores of 5.2 nm is mostly chemically bonded with the hydroxyl groups on the pore surfaces, resulting in higher conductivity than other samples in high relative humidity (over 55%).

Published: June 2019

Benefit of textile reinforced concrete (TRC) is absent of necessary concrete cover because of the durabulity. It allows creating concrete slabs only about 10 mm thick. Therefore, TRC going to be very popular, and more often used in design and load-bearing structures. Big problem in designing of load-bearing structures are rigid frames. The aim of this paper is clarify behavior of thin concrete rigid frames with carbon textile reinforcement by numerical analysis and influences of carbon reinforcement anchoring to the crack opening. Model was created in Atena Science as 2D model and necessary parameters were determined by experimental tests.

Published: June 2019

The paper deals with the design and development of a new and progressive structural types of footbridges with an external tendon used as a main load bearing member. Main goals of the paper are checking the possibilities of using such structures for many different spatial arrangements and especially identifying the problematic aspects of the design. Using the results of research conducted in previous years, the procedure for finding the optimal shape of the cable was described in detail. For specific examples the process of cable shape optimizations is shown. In the next part the influence of various boundary conditions is discussed. The structures were also checked in terms of ULS and SLS limit states. Particular attention is paid to the buckling analysis of the struts and stress distribution in the deck part. The structures were modeled using FEM software Midas Civil. The models used for basic analysis consist of beam and truss elements. For precise analysis the shell models were used. Finally the dynamic behavior analysis was performed according to SÉTRA methodology. The results and outputs of the research should be used by designers who have to deal with similar structural types and they shall hopefully help to identify the most problematic features.
