APRESENTAÇÃO: FORMAÇÃO DE EDUCADORES: CURRÍCULO, CULTURAS E CONTEXTOS.
Authors: Feldmann Marina Graziela , Masetto Marcos Tarciso
Published: September 2017

Em tempos tão fluídos, revestidos de incertezas e perplexidades, falar sobre a questão de formação de educadores perpassada pela tríade: currículo, culturas e contextos nos convida ao exercício de considerar no debate uma multiplicidade de leituras e escritas na busca de se dar voz aos diferentes sujeitos da e na educação.O presente número da Revista e-Curriculum abre espaço para publicação do presente Dossiê, que traz em seu bojo o entendimento de que as concepções sobre o conhecimento, currículo e os processos formativos acontecem e se produzem na prática dos educadores, inflenciando em uma relação de dialeticidade os sentidos atribuidos pelos sujeitos curriculares às diversas situações expressas no ato educativo.O cenário da formação de educadores na sociedade contemporânea é marcado pelos padrões de reestruturação global capitalista que apresenta mudanças econômicas e culturais, as quais moldam e condicionam políticas e estratégias neoliberais instituindo-se como discurso hegemônico. O entendimento a respeito da globalização e de seus efeitos não é uniforme e a incidência sobre as políticas e práticas da educação se apresenta como variada e conflitante dentro de um escopo já marcado por toda ordem de tensões e lutas.
CURRÍCULO, CULTURAS E CONTEXTOS INTEGRADOS À FORMAÇÃO DE EDUCADORES
Authors: Masetto Marcos Tarciso , Feldmann Marina Graziela , Freitas Silvana Alves
Published: September 2017

Este artigo parte da concepção de currículo que emerge da leitura das diretrizes para os cursos de formação de educadores. Identifica-se essa concepção com a de grade curricular, marcada pela falta de integração entre as disciplinas e os conteúdos, pela desconexão tanto com o micro quanto com o macrocontexto das culturas dos sujeitos curriculares. Diante disso, busca-se mostrar a inexorável relação existente entre formação de educadores, currículo, culturas e contextos para evidenciar os desafios de criar novos caminhos para essa formação. O artigo, com abordagem qualitativa, emprega a análise documental da legislação que institui as diretrizes para os cursos de formação de educadores como a Resolução CNE/CP n. 2/2015 e a Deliberação CEE n. 111/2012, atualizada pela Deliberação CEE n. 154/2017 e a análise bibliográfica referente às teorias sobre o currículo e sua relação com as culturas e os contextos, além do relato da memória de um curso de formação continuada oferecido por um dos autores deste texto sobre a vivência de uma professora de Ciências com uma turma de 6º ano de uma escola pública de São Paulo. Os resultados revelaram que a formação de educadores deve incorporar os diversos contextos da cidade, as culturas dos sujeitos, as contradições, os desafios e as possibilidades em busca da superação da concepção de currículo como “grade curricular”. A partir disso, são evidenciados os desafios para criar novos caminhos de formação de educadores que desenvolvam sujeitos curriculares para participarem da construção do currículo.

A violência e a paternidade na cultura: Tropa de Elite
Authors: Wahba Liliana Liviano , Tancetti Barbara
Published: September 2017

O artigo propõe uma leitura da violência a partir da noção do arquétipo paterno na sociedade ocidental pós-moderna, e, mais especificamente, da manifestação violenta e tirânica do pai tanto em seu aspecto individual como coletivo. O objeto de reflexão é o filme Tropa de Elite (2007). Neste, procura-se evidenciar a vertente cultural da figura paterna, que se manifesta nas instituições responsáveis pela estruturação social e a disseminação de valores culturais. Analisa-se o personagem central, capitão Nascimento, em conflito com o dever corporativo – se seu ambiente violento – e a emergência de uma função paterna na família que requer apropriação renovada do feminino. As novas configurações familiares e culturais realçam o paradoxo da figura paterna na contemporaneidade, que é caracterizada por uma coexistência de valores tradicionais e transformações nas estruturas sociais. Essa leitura promove novas perspectivas para a função paterna, bem como suas manifestações no contexto de violência social.

Badingsanak Banjar-Dayak: Religious Identity and Ethnic Economy in South Kalimantan
Authors: Sugiatno Septian Utut
Published: September 2017

Mujiburrahman, Alfisyah, Ahmad Syadzali. 2015. Badingsanak Banjar-Dayak: Identitas Agama dan  Ekonomi Etnisitas di Kalimantan Selatan. Yogyakarta: CRCS-UGMThe Dayak-Banjar relationship is tied up by the myth of the origins of the kinship (Badingsanak) between the Sandayuhan (origins of the Meratus Dayak people) and Bambang Basiwara (origins of the Banjar), but in its development, this issue attracted the attention of some researchers to uncover the beginning of the relationship between these two ethnic groups. This is described by Mujiburrahman, et al., in the book Badingsanak Banjar-Dayak: Religious Identity and Ethnic Economy in South Kalimantan. According to Alfani Daud (1997: 1-4) as quoted by Mujiburrahman et al., In light of the great similarities between the Banjar and Malay languages, it is possible that the Banjar ancestors were descendants of the ethnic Malay who, in the past thousands of years, immigrated from Sumatra and the surrounding areas in this region. He assumed that Meratus were descendants of earlier Malay immigrants, who were driven away by later Malay immigrants. The latter then became the core group of the Banjar.
Use of poliglecaprone 25 for perineal urethrostomy in cats: 61 cases (2007–2013)
Authors: Frem Daniel L. , Hottinger Heidi A. , Hunter Suzanne L. , Trout Nicholas J.
Published: September 2017

OBJECTIVE To determine frequency of postoperative complications in cats undergoing perineal urethrostomy (PU) in which poliglecaprone 25 was used for closure and identify possible predisposing factors for development of complications.

DESIGN Retrospective case series.

ANIMALS 61 cats that underwent PU.

PROCEDURES Medical records for cats that underwent PU at Gulf Coast Veterinary Specialists between 2007 and 2012 were reviewed. Information regarding signalment, perioperative conditions, surgical procedures, treatments, and postoperative complications were obtained from medical records and by telephone follow-up.

RESULTS 11 of 61 (18%) cats developed minor short-term (ie, ≤ 2 months after surgery) complications, 1 of 61 (1.6%) cats developed a major short-term complication requiring surgical revision, and 16 of 38 (42%) cats developed minor long-term complications. No major long-term complications were identified. Preoperative urinary tract infection was significantly associated with development of minor short-term complications, but use of an indwelling urinary catheter after surgery was not significantly associated with development of postoperative complications.

CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that poliglecaprone 25 may be an acceptable suture for apposition of mucosa to skin in cats undergoing PU. Short- and long-term complication rates and percentage of cats requiring revision surgery were comparable to values reported in previous studies in which slowly absorbable or nonabsorbable sutures were used.

OBJECTIVE To determine the incidence of and risk factors for clinical feline herpesvirus (FHV) infection in zoo-housed cheetahs and determine whether dam infection was associated with offspring infection.

DESIGN Retrospective cohort study.

ANIMALS 144 cheetah cubs born in 6 zoos from 1988 through 2007.

PROCEDURES Data were extracted from the health records of cheetahs and their dams to identify incident cases of clinical FHV infection and estimate incidence from birth to 18 months of age. Univariate and multivariable Cox proportional hazards models, controlling for correlations among cheetahs with the same dam, were used to identify risk factors for incident FHV infection.

RESULTS Cumulative incidence of FHV infection in cheetah cubs was 35% (50/144). No significant association between dam and offspring infection was identified in any model. Factors identified as significant through multivariable analysis varied by age group. For cheetahs up to 3 months of age, the most important predictor of FHV infection was having a dam that had received a preparturition FHV vaccine regimen that included a modified-live virus vaccine versus a dam that had received no preparturition vaccine. Other risk factors included being from a small litter, being born to a primiparous dam, and male sex.

CONCLUSIONS AND CLINICAL RELEVANCE This study provided the first population-level characterization of the incidence of and risk factors for FHV infection in cheetahs, and findings confirmed the importance of this disease. Recognition that clinical FHV infection in the dam was not a significant predictor of disease in cubs and identification of other significant factors have implications for disease management.

Problematic Internet Use– An introduction and current status in Nepal
Authors: Shakya R. , Sharma P.
Published: September 2017

Life has become easier with the advent of internet; however excessive use of internet has created a lot of problems. Problematic internet use has been regarded as a separate clinical entity and the researches on its various aspect is on a rise all around the globe in the last decade. This condition though fairly common in Asian context too; has not seen much of recognition in clinical and research setting in Nepal. Review of the major databases has yielded four original studies in Nepal. These cross sectional studies have made an attempt to highlight the prevalence, co-morbidities and mediators to some extent. However, this doesn’t seem to be enough as compared to the literature base needed in the current scenario. Hence, we emphasize on creating awareness among public, early recognition in clinics by clinicians and further research in tertiary health care levels by researchers about this recently rising public health issue of Problematic Internet Use.

Published: September 2017

Introduction: Depression is widely prevalent among the former opioid addicts in Methadone Maintenance Treatment (MMT). It is important to be aware of its severity as it plays a crucial role in methadone dosage, length of time in treatment and the relapse rate. The co-existence of depression is seen to worsen the prognosis in outcome of MMT.Objective: This study aimed to study the prevalence of the symptoms of depression among MMT clients.Method: This is a descriptive and Cross-Sectional study done in 60 MMT clients attending the out patients clinic in Tribhuwan University Teaching Hospital, Nepal. A structured proforma was constructed obtaining the data regarding age, sex, religion, occupation, marital status, literacy rate and socio-economical status. Depressive symptoms were evaluated using 21-item BDI scale.Result: Depressive symptoms were found in 63.3 % of the patients. 38.3% had mild to moderate depression, 15% had moderate to severe, and 11.7% had severe level of depressive symptoms. The depressive symptoms were most prevalent among females (90%) and age group 40-50 years. The prevalence of depressive symptoms were more in unmarried (82%), unemployed (65%), lower socio-economic class(71%) and completing only secondary level in education (73%).Conclusion: The major risk factors for depression among former opioid users were female gender, unmarried, low education level, unemployment and low socio-economic status.
Case report of cerebral phaeohyphomycosis caused by Fonsecaea monophora
Authors: Stokes William , Fuller Jeff , Meier-Stephenson Vanessa , Remington Leah , Meatherall Bonnie L
Published: September 2017

Cerebral phaeohyphomycosis (CP) is a rare cause of fungal central nervous system (CNS) infection. Among the many fungal genera associated with CP, Fonsecaea is rarely the culprit pathogen. As such, Fonsecaea-associated CP is poorly understood, with few cases reported in the literature. The authors report a case of a progressive brain abscess caused by F. monophora in a 63-year-old man with poorly controlled type 2 diabetes, liver cirrhosis, and recent travel to South Sudan. The patient presented with headache and constitutional symptoms 2 days after returning from South Sudan. Fungal culture of a biopsy from a single left frontal abscess isolated a dematiaceous mould that was identified as F. monophora based on colony morphology and DNA sequence analysis of the ribosomal internal transcribed spacer (ITS) region. Despite treatment with liposomal amphotericin B and voriconazole, the patient clinically deteriorated and died. Dematiaceous fungal brain abscesses are a rare cause of CNS infections. Early diagnosis with tissue biopsy is essential for timely access to appropriate antifungal therapy. Complete surgical resection is associated with improved outcomes.
The rare case of a large complex intraosseous cranial arteriovenous malformation with successful multidisciplinary management
Authors: Al-Smadi Anas , Shokuhfar Tahaamin , Johnston Andrew , Alden Tord D. , Bowman Robin , Shaibani Ali
Published: September 2017

Intraosseous cranial arteriovenous malformations (AVMs) are very rare, challenging entities. The authors report the case of an extracranial parietooccipital vascular lesion. A 12-year-old boy presented with accelerated growth of a right scalp lesion over a few months. Digital subtraction angiography showed a large, right parietooccipital intraosseous AVM with multiple complex arterial feeders. Treatment of these lesions is difficult and can necessitate a multidisciplinary approach. In the featured case, 6 embolization procedures were performed over 1 year, including both transarterial and transvenous approaches, followed by total resection. The authors describe what is thought to be the second case of an AVM originating in the cranial bones and the first case with successful multidisciplinary management.
A novel projection of open geometry into rectangular domain for 3D shape parameterization
Authors: Ćurković Milan , Marinić-Kragić Ivo , Vučina Damir
Published: September 2017

Multi-patch shape models of engineering objects, while adequate for representation purposes, may introduce problems related to cross-partition continuity and changing composition of individual partitions in shape optimization. Single-patch integral parameterizations may consequently be the preferred option in cases where the shape can change significantly.

In absence of any topological preparation, fitting of parametric surfaces to point clouds may be satisfactory for simple shapes. However, complex objects involving concave portions and irregular shapes require additional numerical procedures to obtain adequate structured geometry matrices for fitting which need to preserve the original topology.

The overall goal of this paper is to develop a procedure that efficiently handles difficulties related to single-partition parametric surface models of complex-shaped engineering objects. This aspiration involves obtaining a structured geometry matrix even for irregular and concave shapes and developing a dedicated method of projection into a rectangular domain. The performance of the resulting procedure is verified using real engineering objects of complicated 3D shape. Moreover, cases of numerically generated surfaces representative for changing shape compositions with emerging and/or dissolving edges are also included.
Increasing the effectiveness of procurement decisions: The value of big data in the procurement process
Authors: Moretto Antonella , Ronchi Stefano , Patrucco Andrea S.
Published: September 2017

Big data are a commonly discussed topic, and their value in marketing and sales has been thoroughly investigated. Although some authors have also discussed their relevance to purchasing and supply management, the literature on this topic remains scant. This paper aims to investigate the role of big data in supporting the procurement process and the implementation of procurement practices. The main benefits of such procurement practices for companies are highlighted.

By presenting the results of a focus group of procurement professionals and experts and discussing four exploratory case studies (supported by secondary data analysis), the paper addresses 1) how (and in which format) big data affects different activities in the procurement process and 2) which benefits procurement professionals can expect from adopting big data.

Over the last decade, the use of electronic nicotine delivery systems (ENDS), including the electronic cigarette or e‐cigarette, has grown rapidly. More youth now use ENDS than any tobacco product. This extensive research review shows that there are scientifically sound, sometimes competing arguments about ENDS that are not immediately and/or completely resolvable. However, the preponderance of the scientific evidence to date suggests that current‐generation ENDS products are demonstrably less harmful than combustible tobacco products such as conventional cigarettes in several key ways, including by generating far lower levels of carcinogens and other toxic compounds than combustible products or those that contain tobacco. To place ENDS in context, the authors begin by reviewing the trends in use of major nicotine‐containing products. Because nicotine is the common core—and highly addictive—constituent across all tobacco products, its toxicology is examined. With its long history as the only nicotine product widely accepted as being relatively safe, nicotine‐replacement therapy (NRT) is also examined. A section is also included that examines snus, the most debated potential harm‐reduction product before ENDS. Between discussions of NRT and snus, ENDS are extensively examined: what they are, knowledge about their level of “harm,” their relationship to smoking cessation, the so‐called gateway effect, and dual use/poly‐use.CA Cancer J Clin 2017;67:449‐471.©2017 American Cancer Society.
B4C-Al Composites Fabricated by the Powder Metallurgy Process
Authors: Zhang Ling , Shi Jianmin , Shen Chunlei , Zhou Xiaosong , Peng Shuming , Long Xinggui
Published: September 2017

Due to the large thermal neutron absorption cross section of 10B, B4C-Al composites have been used as neutron absorbing materials in nuclear industries, which can offer not only good neutron shielding performance but also excellent mechanical properties. The distribution of B4C particles affects the mechanical performance and efficiency of the thermal neutron absorption of the composite materials. In this study, 15 wt % B4C-Al and 20 wt % B4C-Al composites were prepared using a powder metallurgy process, i.e., ball milling followed by pressing, sintering, hot-extrusion, and hot-rolling. The yield and tensile strengths of the composites were markedly increased with an increase in the milling energy and the percentages of B4C particles. Microstructure analysis and neutron radiography revealed that the high-energy ball milling induced the homogeneous distribution of B4C particles in the Al matrix and good bonding between the Al matrix and the B4C particles. The load transfer ability and mechanical properties of the composites were consequently improved. The results showed the high-energy ball milling process is an appropriate fabrication procedure to prevent the agglomeration of the reinforcement particles even if the matrix to reinforcement particle size ratio was nearly 10.
The Oval Engravings of Nabara 2 (Ennedi, Chad)
Authors: Menardi Noguera Alessandro
Published: September 2017

By revisiting the Nabara 2 shelter in the southern Ennedi (Chad), some previously unreported paintings and a whole set of unexpected oval engravings were surveyed. These engravings, internally decorated with patterns of lines, some featured by a single longitudinal element or a sort of reticular structure, make Nabara 2 an unparalleled site among the hundreds known in the region. Comparison with similar motifs associated to human depictions found at the western termination of the Ennedi Highland suggests these engravings could be depictions of shields, attributable to the pastoral period.

Published: September 2017

Media convergence has changed relationships between existing technologies, industries, markets, and audiences. Smart cities are seen as the logical outcome of media convergence. Big Data form the basis and the output of smart technologies. In the last twenty years, there has been much discussion on smart cities, big data, and the need for sustainability in technological endeavors. This article combines these by providing an overview of the three subjects about their points of intersection. Identifying these points of intersection will help smart city researchers to better understand where there is need for further development towards better standards of living and increased sustainability. This review will provide directions for further research and provide a brief historical overview of how far research has come in the three intertwined identified areas towards designing, adapting, and managing smarter communities.
Peptidylprolyl Isomerases as In Vivo Carriers for Drugs That Target Various Intracellular Entities
Authors: Galat Andrzej
Published: September 2017

Analyses of sequences and structures of the cyclosporine A (CsA)-binding proteins (cyclophilins) and the immunosuppressive macrolide FK506-binding proteins (FKBPs) have revealed that they exhibit peculiar spatial distributions of charges, their overall hydrophobicity indexes vary within a considerable level whereas their points isoelectric (pIs) are contained from 4 to 11. These two families of peptidylprolyl cis/trans isomerases (PPIases) have several distinct functional attributes such as: (1) high affinity binding to some pharmacologically-useful hydrophobic macrocyclic drugs; (2) diversified binding epitopes to proteins that may induce transient manifolds with altered flexibility and functional fitness; and (3) electrostatic interactions between positively charged segments of PPIases and negatively charged intracellular entities that support their spatial integration. These three attributes enhance binding of PPIase/pharmacophore complexes to diverse intracellular entities, some of which perturb signalization pathways causing immunosuppression and other system-altering phenomena in humans.
On the Importance of Both Dimensional and Discrete Models of Emotion
Authors: Harmon-Jones Eddie , Harmon-Jones Cindy , Summerell Elizabeth
Published: September 2017

We review research on the structure and functions of emotions that has benefitted from a serious consideration of both discrete and dimensional perspectives on emotion. To illustrate this point, we review research that demonstrates: (1) how affective valence within discrete emotions differs as a function of individuals and situations, and how these differences relate to various functions; (2) that anger (and other emotional states) should be considered as a discrete emotion but there are dimensions around and within anger; (3) that similarities exist between approach-related positive and negative discrete emotions and they have unique motivational functions; (4) that discrete emotions and broad dimensions of emotions both have unique functions; and (5) evidence that a “new” discrete emotion with discrete functions exists within a broader emotion family. We hope that this consideration of both discrete and dimensional perspectives on emotion will assist in understanding the functions of emotions.
Co-Production of Ethanol and 1,2-Propanediol via Glycerol Hydrogenolysis Using Ni/Ce–Mg Catalysts: Effects of Catalyst Preparation and Reaction Conditions
Authors: Menchavez Russel , Morra Matthew , He B.
Published: September 2017

Crude glycerol from biodiesel production is a biobased material capable of co-producing biofuels and chemicals. This study aimed to develop a line of Ni catalysts supported on cerium–magnesium (Ce–Mg) to improve the process efficiency of glycerol hydrogenolysis for ethanol and 1,2-propanediol (1,2-PDO). Results showed that catalytic activity was greatly improved by changing the preparation method from impregnation to deposition precipitation (DP), and by adjusting calcination temperatures. Prepared via DP, the catalysts of 25 wt % Ni supported on Ce–Mg (9:1 mol/mol) greatly improved the effectiveness in glycerol conversion while maintaining the selectivities to ethanol and 1,2-PDO. Calcination at 350 °C provided the catalysts better selectivities of 15.61% to ethanol and 67.93% to 1,2-PDO. Increases in reaction temperature and time improved the conversion of glycerol and the selectivity to ethanol, but reduced the selectivity to 1,2-PDO. A lower initial water content led to a higher conversion of glycerol, but lower selectivities to ethanol and 1,2-PDO. Higher hydrogen application affected the glycerol conversion rate positively, but the selectivities to ethanol and 1,2-PDO negatively. A comparison to the commercial Raney® Ni catalyst showed that the Ni/Ce–Mg catalyst developed in this study showed a better potential for the selective co-production of ethanol and 1,2-PDO from glycerol hydrogenolysis.
A Potential Novel Mechanism for Vagus Nerve Stimulator-Related Central Sleep Apnea
Authors: Forde Inga , Mansukhani Meghna , Kolla Bhanu , Kotagal Suresh
Published: September 2017

The treatment of epilepsy with vagus nerve stimulation can inadvertently cause obstructive and central sleep apnea (CSA). The mechanism for CSA seen in patients with a vagus nerve stimulator (VNS) is not fully known. We describe the case of a 13-year-old girl in whom VNS activation induced tachypnea and post-hyperventilation central apnea. Following adjustment of VNS settings, the post-hyperventilation CSA resolved. Polysomnography may assist with management when patients with epilepsy develop sleep disruption after VNS placement.
Pipelined Architecture of Multi-Band Spectral Subtraction Algorithm for Speech Enhancement
Authors: Bahoura Mohammed
Published: September 2017

In this paper, a new pipelined architecture of the multi-band spectral subtraction algorithm has been proposed for real-time speech enhancement. The proposed hardware has been implemented on field programmable gate array (FPGA) device using Xilinx system generator (XSG), high-level programming tool, and Nexys-4 development board. The multi-band algorithm has been developed to reduce the additive colored noise that does not uniformly affect the entire frequency band of useful signal. All the algorithm steps have been successfully implemented on hardware. Pipelining has been employed on this hardware architecture to increase the data throughput. Speech enhancement performances obtained by the hardware architecture are compared to those obtained by MATLAB simulation using simulated and actual noises. The resource utilization, the maximum operating frequency, and power consumption are reported for a low-cost Artix-7 FPGA device.
Impact of Pre-Pregnancy Weight and Gestational Weight Gain on Birth Outcomes by Nativity in the United States: A Systematic Review
Authors: Tabb Karen , Malinga Tumani , Pineros-Leano Maria , Andrade Flavia
Published: September 2017

Background: Disparities in birth outcomes remain a problem in the United States. This study examined whether pre-pregnancy weight and gestational weight gain moderate the association between nativity and birth outcomes in the United States. Methods: We conducted a systematic review using Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. We searched PubMED, CINAHL, PsychInfo, and Cochrane Database of Systematic Reviews for relevant articles published before May 27, 2016. Results: Four articles met the eligibility criteria by adjusting for pre-pregnancy or gestational weight gain when examining birth outcomes by nativity. Results: Results from these studies show statistically significant differences in the risk of delivering low birth weight babies between foreign-born and U.S.-born women. These differences remained after adjusting for pre-pregnancy weight or gestational weight gain. However, results stratified by nativity still vary significantly by race/ethnicity. Conclusion: Few investigations include pre-pregnancy weight and gestational weight gain when examining differences in birth outcomes by nativity. Additional studies are needed to examine possible effect modification of these weight variables on the association between nativity and birth outcomes.
Three Types of Intimate Relationships among Individuals with Chronic Pain and a History of Trauma Exposure
Authors: Van den Berk-Clark Carissa , Weaver Terri , Schneider F.
Published: September 2017

Individuals with chronic pain often have psychiatric disorders, such as depression and posttraumatic stress disorder (PTSD), which can affect their intimate relationship satisfaction and stability. Little is known about the nature of support stemming from chronic pain patients’ intimate relationships, and therefore, this study sought to: (1) use cluster modeling to construct specific intimate relationship groups based on types of support patients receive, and (2) determine if there is a relationship between support type and PTSD, chronic pain, anxiety, and depression. Ward’s method of cluster analysis in Stata was used to create groups based on the level of informational, affirmation, confident, emotional, and fun support received from chronic pain patients’ most intimate relationship. Three types of support were identified: high (type 1, n = 17), high emotional/low instrumental (type 2, n = 9), and unstable (type 3, n = 15). Types 1 and 3 included more family members (Type 1: 100%, Type 2: 93%), than type 2 (77%). Type 2 patients experienced more trauma (Mean = 9.4 ± 1.7 vs. 7.5 ± 0.88 for types 1 and 3) and were significantly more likely to have PTSD (X2 = 7.91, p < 0.05. Patients with low familial support may also benefit from PTSD screening and referral but further study is needed.
Computer Science Papers in Web of Science: A Bibliometric Analysis
Authors: Fiala Dalibor , Tutoky Gabriel
Published: September 2017

In this article we present a bibliometric study of 1.9 million computer science papers published from 1945 to 2014 and indexed in Web of Science. We analyze both the quantity and the impact of these publications according to document types, languages, disciplines, countries, institutions, and publication sources. The most frequent author keywords, cited references, and cited papers as well as the distribution of the number of references and citations per paper and of the age of cited references are also explored. Since conference proceedings play a tremendous role in this scientific field, we investigate the time and place of computer science conferences in terms of the most prolific months and locations. And, last but not least, the production of journal articles and conference papers over the whole time period and the level of collaboration in different computer science disciplines are inspected. One of the main results is the finding that “Artificial Intelligence” is the most productive subfield of computer science, but “Interdisciplinary Applications” has the highest relative impact.

A visuo-haptic augmented reality (VHAR) interface is presented enabling an operator to teleoperate an unmanned aerial vehicle (UAV) equipped with a custom CdZnTe-based spectroscopic gamma-ray detector in outdoor environments. The task is to localize nuclear radiation sources, whose location is unknown to the user, without the close exposure of the operator. The developed detector also enables identification of the localized nuclear sources. The aim of the VHAR interface is to increase the situation awareness of the operator. The user teleoperates the UAV using a 3DOF haptic device that provides an attractive force feedback around the location of the most intense detected radiation source. Moreover, a fixed camera on the ground observes the environment where the UAV is flying. A 3D augmented reality scene is displayed on a computer screen accessible to the operator. Multiple types of graphical overlays are shown, including sensor data acquired by the nuclear radiation detector, a virtual cursor that tracks the UAV and geographical information, such as buildings. Experiments performed in a real environment are reported using an intense nuclear source.
A NEW TIME-DEPENDENT TRADING STRATEGY FOR SECURITIZED REAL ESTATE AND EQUITY INDICES

Published: September 2017

The “buy-and-hold” strategy based on the EMH has been adopted by many investors for long. However, the global financial crisis in 2008 caused more doubt to be cast on EMH. Therefore, many scholars have attempted to create a trading strategy which can outperform the “buy-and-hold” strategy. In this study, we use the Shiryaev-Zhou index to derive a new generalized time-dependent strategy of which the moving-window size can be changed to see how the moving-window size affects the resulting profit of our strategy. We test our strategy on the securitized real estate and general equity indices of six economies, and find the optimal moving-window size for our strategy on each stock index. The results show that when the optimal moving-window size is used, our strategy outperforms the “buy-and-hold” strategy for most cases. Furthermore, during stock market downturns, it’s advisable to adopt our strategy, preferably with larger moving-window sizes, to prevent losses when the stock prices fall rapidly. However, during long periods of booms, it’s better to adhere to the “buy-and-hold” strategy. This implies that we should switch strategies when market fundamentals changes significantly. Property practitioners can also apply this strategy for a better portfolio management to increase their profit.
RIPPLE EFFECT IN REGIONAL HOUSING AND LAND MARKETS IN IRAN: IMPLICATIONS FOR PORTFOLIO DIVERSIFICATION

In recent years, real estate has become a very popular investment choice for Iranian investors due to several interrelated economic and political reasons. The purpose of this study is to find out how real estate investors can gain diversification benefits from investing within the real estate sector across provinces of Iran. We use semi-annual data from selected provinces of Iran over the period of 1993–2014 and apply univariate Lagrange multiplier unit root tests with one and two structural breaks to the ratio of the provincial to national house and residential land prices respectively. We find diversification benefit can be gained by investing in housing markets across provinces because house prices in half of the sample provinces tend to drift away from house prices in the rest of the country. In addition, our results show that it is difficult to create an adequately diversified portfolio in a residential land market because shocks to the residential land prices of provinces ripple out across the nation. These findings should be valuable to domestic and foreign investors who are interested in the Iranian real estate sector, especially after the lifting of several international economic sanctions.

Published: September 2017

LitPOS (Lithuanian Positioning System), the network of permanent reference GNSS stations, became operational in July 2007. It provides data both for real-time and post-processing applications. LitPOS stations cover the whole territory of Lithuania. Total number of LitPOS GNSS stations during 2007–2014 period was 25 (since 2015 – 30 stations). Also LitPOS network includes 3 ASG-EUPOS (Poland) and 6 LATPOS (Latvia) stations. LitPOS network data re-processing was done using Bernese (BSW5.2 update 2016 01 08) software. Software was slightly improved by editing scripts and writing procedures for RINEX files preparation, for downloading other necessary data, and for getting two processing solutions from single BPE (Bernese Process Engine) process (total network and sub-network without Polish and Latvian stations).
Accuracy Assessment of Mobile Laser Scanning Elevation Data in Different Vegetation Areas

Due to the overall development of technology, laser scanning has reached a new level. During the last decade, all the different technologies necessary for mobile laser scanning, have been developed. Due to the fact that mobile laser scanning brings the need to process very large amounts of data, development of computers and software is also very important. The aim of current research was to assess the accuracy of mobile laser scanning elevation data in different vegetation areas and to explore if mobile laser scanning could be used as an alternative to aerial laser scanning. This article only covers the data collecting, processing and accuracy assessment aspects of the research. Data used in current study was collected in summer of 2015, during mobile laser scanning of Põltsamaa-Kärevere section of E263 route (Tallinn-Tartu-Võru-Luhamaa). Three smaller, differently vegetated, sections were picked from the large project to study the accuracy of elevation data. For accuracy assessment, the mobile laser scanning elevation data was compared to the checkpoints measured with GNSS (Global Navigation Satellite Systems) device. Ground profiles were drawn based on mobile laser scanning data. For objective assessment, accuracy of mobile laser scanning elevation data was compared to accuracy of ground profile elevation data and aerial laser scanning elevation data. The study found that the RMSE (Root Mean Square Error) in the I section, which was a field vegetated with 1 metre high crop, was 0,98 metres. RMSE in the II section, which was a pasture with low and sparse vegetation, was 0,23 metres. RMSE in the III section, which contained a bushy ditch and a field behind it, was 0,61 metres. Results show that the accuracy of mobile laser scanning elevation data depends substantially on the density of vegetation in scanned areas and that drawing ground profiles reduced the RMSE of mobile laser scanning elevation data. Results show that the accuracy of mobile laser scanning elevation data depends substantially on the density of vegetation in scanned areas. On this basis it can be concluded, that the most reasonable time to conduct mobile laser scanning would be during a season, when vegetation is the sparsest. It can also be concluded that drawing ground profiles makes mobile laser scanning data more accurate.
Designing Solutions by a Student Centred Approach: Integration of Chemical Process Simulation with Statistical Tools to Improve Distillation Systems
Authors: Joao Isabel M. , Silva Joao M.
Published: September 2017

Projects thematically focused on simulation and statistical techniques for designing and optimizing chemical processes can be helpful in chemical engineering education in order to meet the needs of engineers. We argue for the relevance of the projects to improve a student centred approach and boost higher order thinking skills. This paper addresses the use of Aspen HYSYS by Portuguese chemical engineering master students to model distillation systems together with statistical experimental design techniques in order to optimize the systems highlighting the value of applying problem specific knowledge, simulation tools and sound statistical techniques. The paper summarizes the work developed by the students in order to model steady-state processes, dynamic processes and optimize the distillation systems emphasizing the benefits of the simulation tools and statistical techniques in helping the students learn how to learn. Students strengthened their domain specific knowledge and became motivated to rethink and improve chemical processes in their future chemical engineering profession. We discuss the main advantages of the methodology from the students’ and teachers perspective
Evidencing the Value of Inquiry Based, Constructionist Learning for Student Coders

For the last decade, there has been growing interest in the STEAM approach (essentially combining methods and practices in arts, humanities and social sciences into STEM teaching and research) to develop better research and education, and enable us to produce students who can work most effectively in the current and developing market-place. However, despite this interest, there seems to be little quantitative evidence of the true power of STEAM learning, especially describing how it compares and performs with respect to more established approaches. To address this, we present a comparative, quantitative study of two distinct approaches to teaching programming, one based on STEAM (with an open-ended inquiry-based approach), the other based on a more traditional, non-STEAM approach (where constrained problems are set and solved). Our key results evidence how students exhibit different styles of programming in different types of lessons and, crucially, that students who tend to exhibit more of the style of programming observed in our STEAM lessons also tend to achieve higher grades. We present our claims through a range of visualisations and statistical validations which clearly show the significance of the results, despite the small scale of the study. We believe that this work provides clear evidence for the advantages of STEAM over non-STEAM, and provides a strong theoretical and technological framework for future, larger studies.
Figures de l’étranger à Versailles
Authors: Sabatier Gérard
Published: September 2017

Les programmes décoratifs de Versailles contemporains des premières guerres du roi (1664-1678) se composent de figures de convention tirées de la mythologie, de l’histoire ancienne ou du répertoire allégorique, réitération du décor impérial de celui qui, plus que Roi-Soleil, se voulait Louis-Auguste. Quelques-unes, cependant, sont représentées de façon réaliste. Rompant par leur étrangeté, ce sont les figures de l’étranger. Nations des quatre continents sur les parois de l’escalier des Ambassadeurs, ambassadeurs dans son plafond ou dans les tableaux ovales de la Grande Galerie, ce sont des étrangers révérencieux. Nus (les Turcs) ou en armures « gothiques » (Espagnols, Allemands, Hollandais…), ce sont les ennemis (les Français et le roi sont à la romaine). « À la moderne » elles aussi, trois femmes incarnent les Puissances hostiles à la France. Minoritaires à Versailles, les figures de l’étranger font l’objet d’un traitement adapté à leur fonction et à leur relation avec le roi : déférence, soumission, disqualification.
