Reward-Based Crowdfunding Campaigns: Informational Value and Access to Venture Capital
Authors: Roma Paolo , Gal-Or Esther , Chen Rachel R.
Published: April 2018

We consider an entrepreneur who designs a reward-based crowdfunding campaign when the campaign provides a signal about the future demand for the product and subsequent venture capital is needed. We find that both the informativeness of the campaign and considerations related to gaining access to venture capital funding affect the entrepreneur’s choice of campaign instruments, as well as her decision of whether to run a campaign. In particular, entrepreneurs should launch the campaign either when it is highly informative or when it is not informative at all. For relatively low levels of informativeness, but not so low that the venture capitalist (VC) completely ignores the campaign outcome in his funding decision, our study suggests that the entrepreneur might forgo the opportunity of acquiring information via crowdfunding because the benefits of crowdfunding are insufficient to offset the risk of campaign failure. We also find that the preference of entrepreneurs in favor of crowdfunding is stronger than that of VCs. For backers, we point out that in addition to the risk inherent in new product development, they should be cognizant of the risk that successful campaigns do not guarantee subsequent VC funding. As the use of crowdfunding platforms becomes more prevalent for entrepreneurial projects, our study offers a deeper understanding of the dual role of reward-based crowdfunding in terms of acquiring demand information and raising capital for early-stage start-ups.

Closing a Supplier’s Energy Efficiency Gap Through Assessment Assistance and Procurement Commitment
Authors: Nguyen Jason , Donohue Karen , Mehrotra Mili
Published: April 2018

This paper analyzes the energy efficiency (EE) investment decisions of a capital-constrained manufacturer that competes with an alternative supplier for the business of a large industrial buyer. Through a series of game-theoretic models, we characterize when it is beneficial for the buyer to offer EE instruments, including assessment assistance and procurement commitment, and how these instruments interact with third-party assessment assistance to affect the supplier’s EE investment level. We find that assessment assistance helps reduce the EE gap but procurement commitment is required to eliminate it. We also find that the availability of third-party assessment assistance reduces the buyer’s incentive to offer both of its instruments, a scenario that potentially lowers the supplier’s EE investment level. Our findings provide insights for buyers and policy makers interested in improving supply-chain EE.

Occurrence of Fibrous Chrysotile and Tremolite in the Çankiri and Ankara Regions, Central Anatolia, Turkey
Authors: Külah Tacit , Kadir Selahattin , Erkoyun Hülya , Huggett Jennifer , Atabey Eşref
Published: April 2018

Numerous occurrences of asbestos minerals, notably chrysotile and tremolite, are to be found on fracture surfaces in thrust fault deformation zones of Cretaceous dunite-harzburgite and pyroxenite in the Çankırı and Ankara regions, central Anatolia, Turkey. Consequently, potential exists for the development of regional malignant mesothelioma. The means of serpentinization, such as reaction of seawater during accretion of the upper ophiolitic mantle crust in a subduction zone and/or following uplift of ophiolitic units and the influence of hydrothermal/meteoric fluids along fractures, were investigated. Cretaceous dunite-harzburgite and localized pyroxenite rocks are mainly composed of serpentinized olivine and pyroxene associated with opaque minerals and Fe-(oxyhydr)oxide phases. Smectite, chlorite, illite, kaolinite, hydromagnesite, goethite, quartz, and opal-CT are also present. Chrysotile and localized tremolite occur either as a mesh, a suboriented to oriented long-fiber bundle, or as fiber-filling millimetric micro-vein textures on relicts of olivine and pyroxene (enstatite, augite). The chrysotile and tremolite have non-pseudomorphic textures developed under high pressure and temperature. The textures suggest authigenic formation of chrysotile and tremolite via a dissolution and precipitation mechanism. Additionally, spherical structures of opal-CT and locally platy hydromagnesite crystals either enclose or are developed within chrysotile/tremolite fiber bundles. The leaching of MgO, Fe2O3, Al2O3, Ni, Cr, and Nb, an increase in the LREE/HREE ratio, and negative Eu anomalies in the dunite-harzburgite and pyroxenite, and asbestos samples suggest that the chrysotile and tremolite were derived from the serpentinization of olivine and pyroxene. The chrysotile and tremolite were developed along fractures by hydrothermal fluid alteration during accretion and/or following the uplift of ophiolitic units of the region under high pressure and temperature conditions. This interpretation is also supported by isotope data and the calculated formation temperature of 170–555°C for chrysotile and tremolite. The average structural formulae for chrysotile and tremolite are (NanK0.03)(Mg5.54Fe0.09Al0.05Ca0.01Mn0.001) (Si3.96Al0.03)O10(OH)8 and (Na0.17K0.07)(Ca1.59Mg0.19Mn0.002)(Mg4.72Fe0.28)(Si7.86Al0.1Fe0.06)O22(OH)2, respectively.
Quantitative X-Ray Powder Diffraction and the Illite Polytype Analysis Method for Direct Fault Rock Dating: A Comparison of Analytical Techniques
Authors: Boles Austin , Schleicher Anja M. , Solum John , van der Pluijm Ben
Published: April 2018

Illite polytypes are used to elucidate the geological record of formations, such as the timing and provenance of deformations in geological structures and fluids, so the ability to characterize and identify them quantitatively is key. The purpose of the present study was to compare three X-ray powder diffraction (Q-XRPD) methods for illite polytype quantification for practical application to directly date clay-rich fault rocks and constrain the provenance of deformation-related fluids in clay-rich brittle rocks of the upper crust. The methods compared were WILDFIRE© (WF) modeling, End-member Standards Matching (STD), and Rietveld whole-pattern matching (BGMN®). Each technique was applied to a suite of synthetic mixtures of known composition as well as to a sample of natural clay gouge (i.e. the soft material between a vein wall and the solid vein). The analytical uncertainties achieved for these synthetic samples using WF modeling, STD, and Rietveld methods were ±4–5%, ±1%, and ±6%, respectively, with the caveat that the end-member clay mineral used for matching was the same mineral sample used in the test mixture. Various particle size fractions of the gouge were additionally investigated using transmission electron microscopy (TEM) to determine polytypes and laser particle size analysis to determine grain size distributions. The three analytical techniques produced similar 40Ar/39Ar authigenesis ages after unmixing, which indicated that any of the methods can be used to directly date the formation of fault-related authigenic illite. Descriptions were included for pre-calculated WF illite polytype diffractogram libraries, model endmembers were fitted to experimental data using a least-squares algorithm, and mixing spreadsheet programs were used to match end-member natural reference samples.
Behavioral Interventions for Inappropriate Sexual Behavior in Individuals With Developmental Disabilities and Acquired Brain Injury: A Review
Authors: Clay Casey J. , Bloom Sarah E. , Lambert Joseph M.
Published: April 2018

Inappropriate sexual behavior (ISB) is a common, but understudied, issue for individuals diagnosed with developmental disabilities (DD), intellectual disability (ID), and/or acquired brain injuries (ABI). We conducted a systematic review to identify, analyze, and synthesize published behavior-analytic approaches to intervention for ISB in DD, ID, or ABI populations. Twenty-three studies employing single-subject research methodology were identified and evaluated using quality indicators described by Horner et al. (2005). Results of our analysis suggest insufficient evidence exists to consider any specific response-suppression technique an overarching treatment for decreasing ISB using the Horner et al. criteria. However, broadly speaking, behavior analytic approaches have been highly effective. Practitioners should consider function-based intervention and draw from studies identified as having strong supporting evidence.

Published: April 2018

The desert rose (Adenium obesum) has been highlighted in the internal market, however there are not many studies related to its demands regarding its nutrition and substrates. The aim of this study was to evaluate the effect of different fertilizations and its interactions with different substrates in the initial growth of the desert rose. The seedlings of desert rose with 60 days have been potted transplanted with a capacity of 0.415 L, filled with two kinds of substrates: sand + coconut fiber and sand + composted pine powder. Four different fertilization managements have been done: without fertilization, application of the Hoagland & Arnon nutrient solution; application of NH3 NO4 at 590 g L-1 of nitrogen (N); and the application of the Hoagland & Arnon nutrient solution modified through the addition of NH3 NO4 , increasing the concentration of N to 800 g L-1. The solutions have been applied biweekly adding 50 mL per pot. The experiment has been entirely randomized in a 2x4 factorial design, with 10 repetitions. After 150 days from the beginning of the fertilizations the phytometrical parameters evaluated were: height of the shoot; diameter of the basal caudex; number of shoots; dry mass of the roots, caudex and leaves; and determination of the levels and accumulation of macronutrients in the shoot, and the pH and electrical conductivity of the substrates. The evaluated data have been submitted to an analysis of variance and the Tukey test compared through the test at 5% of error probability. For all the evaluated parameters, when the composted pine mixture was used, the seedlings showed a higher development compared to coconut fiber mixture. The seedlings had a better performance with the modified Hoagland solution for height, number of shoots, caudex diameter and leaf dry mass in both substrates. The use of the sand + pine powder (1:1 v v-1) and the fertilization with Hoagland & Arnon solution combined with the NH3 NO4 solution provided a better initial growth on the desert rose.

Authors: Zhang Jinshan , Cai Jing , Liu Shulan , Zhang Xianmei
Published: April 2018

Objective

To investigate the diagnostic value of dual-energy lung perfusion imaging (DEPI) using a dual-source CT system for the pulmonary embolism (PE).

Methods

50 patients in high acute PE prevalence were enrolled to accept the DEPI (lung perfusion image and CTA image of pulmonary artery acquired through the Dual Energy software) and emergent DSA angiography (golden diagnostic criterion).

Results

Patients using CT had significantly reduced examination duration and dosage of contrast agent than those using DSA examination, (P < 0.05). In total, 260 pulmonary arteries and 1020 pulmonary segments were examined through CTA, in which embolisms were identified in 50 lobes of lung, 108 pulmonary segments and 82 sub-segments. Reduction or lack of perfusion was identified through DEPI in 48 lobes of lung (concordance rate of 96.0%), 103 pulmonary segments (concordance rate of 95.4%) and 78 subsegments (concordance rate of 95.1%). The comparison of embolism quantity and morphological characteristics of pulmonary artery between CTA images and DEPI images showed no statistically significant difference.

Conclusion

Better application value can be achieved in the diagnosis of pulmonary embolism by dual-energy lung perfusion imaging using a dual-source CT system.
Report formatting in laboratory medicine – a call for harmony
Authors: Jones Graham R.D. , Legg Michael
Published: April 2018

The results of medical laboratory testing are only useful if they lead to appropriate actions by medical practitioners and/or patients. An underappreciated component of the medical testing process is the transfer of the information from the laboratory report into the reader’s brain. The format of laboratory reports can be determined by the testing laboratory, which may issue a formatted report, or by electronic systems receiving information from laboratories and controlling the report format. As doctors can receive information from many laboratories, interpreting information from reports in a safe and rapid manner is facilitated by having similar report layouts and formats. Using Australia as an example, there is a wide variation in report formats in spite of a body of work to define standards for reporting. In addition to standardising of report formats, consideration needs to be given to optimisation of report formatting to facilitate rapid and unambiguous reading of the report and also interpretation of the data. Innovative report formats have been developed by some laboratories; however, wide adoption has not followed. The need to balance uniformity of reporting with appropriate innovation is a challenge for safe reporting of laboratory results. This paper discusses the current status and opportunity for improvement in safety and efficiency of the reading of laboratory reports, using current practise and developments in Australia as examples.

Authors: Aleksova Lyubka , Ali Metin M. , Chakarov Djevdet I. , Yozgyur Zeynep M.
Published: April 2018

Aim: To compare the level of intra-operative identification of external branch of the superior laryngeal nerve (EBSLN) through classical conventional clinical methods of prevention against those applying intraoperative neuromonitoring (IONM).

Materials and methods: The study included 102 patients with interventions on the thyroid gland performed in the surgical clinics of St George University Hospital and the Department of Special Surgery of Plovdiv Medical University. All operative procedures were performed by the standard technique of capsular dissection and IONM.

Results: Of all 102 thyroid procedures 87 (85.3%) patients underwent total thyroidectomy and 15 (14.7%) had unilateral thyroid lobectomy. One hundred fifty-five (82.01%) out of 189 expected EBSLN were identified and investigated intraoperatively when trying to identify visually EBSLN by the so called classical (conventional) methods of prevention. With the use of IONM, 181 (96.76%) EBSLN were correctly identified. Compared to the preliminary results of visual identification - 155/189 (82.01%) EBSLN, the degree of identification of EBSLN through IONM reached 96.76% which is a statistically significant difference (P <0.05)

Conclusion: The use of IONM during thyroid resection significantly improves the degree of identification of EBSLN compared to conventional means of prevention. Routine use of IONM in surgical interventions on the thyroid gland will be beneficial for more secure identification and prevention of EBSLN.

Childhood obesity: how long should we wait to predict weight?
Authors: Butler Éadaoin M. , Derraik José G.B. , Taylor Rachael W. , Cutfield Wayne S.
Published: April 2018

Obesity is highly prevalent in children under the age of 5 years, although its identification in infants under 2 years remains difficult. Several clinical prediction models have been developed for obesity risk in early childhood, using a number of different predictors. The predictive capacity (sensitivity and specificity) of these models varies greatly, and there is no agreed risk threshold for the prediction of early childhood obesity. Of the existing models, only two have been practically utilized, but neither have been particularly successful. This commentary suggests how future research may successfully utilize existing early childhood obesity prediction models for intervention. We also consider the need for such models, and how targeted obesity intervention may be more effective than population-based intervention.
Difficulty in visual sex identification: a case study on bank voles
Authors: Bartolommei Paola , Bencini Cristina , Bonacchi Andrea , Gasperini Stefania , Manzo Emiliano , Cozzolino Roberto
Published: April 2018

The present study aims at quantifying the error in visual sexing of live-trapped bank voles and evaluating if animal body weight and experience of field workers affected the ability to determine the sex of voles. The error in sex attribution involved 25.6% of non-reproductive individuals, pointing out the need to validate the field sex identification. Body weight of voles did not affect the ability of trappers to visually discriminate the sex of animals. Field workers had similar percentages of error independently of their expertise in vole sexing but they also showed a sex-bias in wrongly sexed individuals.

Authors: Filipce Venko , Caparoski Aleksandar , Kamiloski Tomi
Published: April 2018

Introduction. Subarachnoid hemorrhage is unfortunately the most common manifestation of intracranial aneurysms.

Methods. Very frequently there is a dilemma on whether patient should be operated on early i.e. in the first 72 hours or late i.e. two weeks after the bleeding. Many factors influence this decision, some of them being neurological condition at admission, age of the patient, eventual compressive intracerebral hematoma. We present our experiences in treatment and decision making of these patients as well as the outcome of early versus late surgically treated patients.

Results. Patients were divided in five groups according to the grade of neurological condition on admition. Within each group statistical analysis was conducted to compare early versus late surgery. Results have show difference within each group of patients.

Conclusion. In our study, patients that have been admitted in good clinical condition and operated on early had better outcome than patients operated late.
Constructing analytic solutions on the Tricomi equation
Authors: Ghiasi Emran Khoshrouye , Saleh Reza
Published: April 2018

In this paper, homotopy analysis method (HAM) and variational iteration method (VIM) are utilized to derive the approximate solutions of the Tricomi equation. Afterwards, the HAM is optimized to accelerate the convergence of the series solution by minimizing its square residual error at any order of the approximation. It is found that effect of the optimal values of auxiliary parameter on the convergence of the series solution is not negligible. Furthermore, the present results are found to agree well with those obtained through a closed-form equation available in the literature. To conclude, it is seen that the two are effective to achieve the solution of the partial differential equations.

Published: April 2018

In this study, six different types of polysulfone hollow fiber membranes were fabricated from the same polymeric dope solution by manipulating several important parameters during the spinning process, aiming to find the best membrane supports for the coating layer in the gas separation process. The experimental results showed that upon the polydimethylsiloxane (PDMS) coating process, the gas pair selectivities of all six types of membranes were significantly increased with respect to carbon dioxide (CO2)/methane (CH4) and oxygen (O2)/nitrogen (N2) separation. However, the membrane support spun at higher air gap and lower dope extrusion rate was found to be the best support for PDMS coating owing to its good structural integrity that led to a good balance between gas permeance and gas pair selectivity. Further investigation showed that the use of poly(ether block amide) (Pebax) as coating material did not certainly improve both gas permeance and the selectivity of hollow fiber membranes, although Pebax was previously reported to exhibit better performance than PDMS in flat sheet membranes. One of the main reasons is the difficulty of forming a defect-free Pebax coating layer on the outer surface of hollow fibers owing to the stickiness issue among fibers upon coating. More research is still needed to optimize the Pebax coating solution and its drying process in order to achieve the full potential of such coating material for hollow fiber membranes.

Published: April 2018

The recent recognition that grade 3 (G3) neuroendocrine neoplasms (NENs) can be divided into two different categories according to the histopathological differentiation, that is G3 neuroendocrine tumors (NETs) and G3 neuroendocrine carcinomas (NECs) has generated a lot of interest concerning not only the diagnosis, but also the differential management of such new group of NENs. However, several issues need to be fully clarified in order to put G3 NETs and G3 NECs in the right place. The aim of this review is to focus on those issues that are still undetermined starting from the current knowledge, evaluating the available evidence and the possible clinical implications.
Класифікаційна модель внутрішньозональної різноманітності лісів
Authors: Migunova E.
Published: April 2018

Обґрунтовано розуміння едафічної сітки Крюденера-Погребняка як сполученої класифікації лісів і грунтів у межах однорідних за кліматом регіонів. Вихідним пунктом є виділення зон, у горах – висотних поясів. Подібні за складом типи лісу в різних зонах, наприклад соснові бори, рекомендовано відносити не до однакових, а до аналогічних типів, характеризуючи їх специфіку в різних зонах.

Вивчення грунтів як середовища існування потрібно проводити з наголосом не тільки на їхню генетичну приналежність, оцінювану за будовою верхніх горизонтів, але, насамперед, на їхній мінеральний склад, що проявляється через гранулометричний склад, який визначає рівень забезпеченості грунтів елементами живлення рослин і водно-фізичні властивості.

Більшість високопродуктивних насаджень у різних зонах приурочені до ділянок, які знаходяться на шляхах міграції грунтового стоку, що створює на них своєрідні умови природної гідропоніки. Так, зокрема, Брянський масив приурочений до земель, по яких йде міграція багатого мінеральними сполуками стоку зі Середньоросійської височини в низинне Полісся. Більше того, стійке співіснування лучних степів і дібров в Лісостепу зумовлено тим, що діброви формуються на корінних берегах річок, на яких концентрується грунтовий стік різної інтенсивності з вододілів. Звичайні ґрунтові дослідження не дають змоги виявити наявність такого стоку. Про нього можна судити за помітно більшою зволоженістю грунтів у найбільш посушливі періоди вегетації.

Найбільш важливим є встановлення лісовими типологами факту того, що вся зональна і внутрішньозональна різноманітність природи зумовлена родючістю поверхні Землі, відмінностями в її забезпеченості екологічними ресурсами. Встановлено жорстку зумовленість складу і продуктивності лісових насаджень трьома основними лімітованими екологічними ресурсами клімату і грунтів – теплом, вологою і живленням, які формують в підсумку той чи інший рівень родючості середовища. Взаємно зумовлені лісотипологічні класифікаційні моделі лісів та їх середовища, кліматична – в координатах кількості тепла і атмосферних опадів та едафічна – в координатах вмісту основних елементів живлення рослин і доступної вологи в грунті, дають змогу систематизувати зональну і внутрішньозональну різноманітність не лише лісів, але й природи загалом.

Вангутта (S. vanhouttei (Brio) Zab.), с. верболистої (S. salicifolia L.), жимолості звичайної (Lonicera xуlosteum L.), ж. татарської (L. tatarica L.), бирючини звичайної (Ligustrum vulgare L.), свидини кров’яної (Cornus sanguinea L.) та с. білої (C. alba L.) у зелених насадженнях міста Біла Церква та у лісових культурах Томилівського лісництва ДП «Білоцерківське лісове господарство». Періодично проводили обрізування їх надземної частини. Встановлено, що обрізування крон з періодичністю 15-17 років сприяє збільшенню довговічності кущів досліджуваних видів на 33-35 років і більше. За відсутності таких заходів повне відмирання кущів відбувається у віці 19-20 років. Періодичне обрізування сприяє також підвищенню лісівничих та декоративних властивостей кущів.

Теоретико-методологічні основи оцінювання енергетичного потенціалу деревної біомаси лісів на засадах сталого лісоуправління
Authors: Vasylyshyn R.
Published: April 2018

Опрацьовано термінологічно-поняттєвий інструментарій та теоретико-методологічний базис для розроблення методики оцінювання енергетичного потенціалу деревної біомаси лісів, що відповідає концептуальним засадам сталого розвитку.

Розраховано показники енергоємності основних компонентів деревної біомаси. Для їх встановлення використано якісні характеристики компонентів біомаси та кількісні параметри енергоємності однієї тонни вуглецю, депонованого у фітомасі дерев.

Встановлено, що найвищою енергоємністю характеризується деревина граба звичайного. Найнижчу енергоємність виявлено у компонентів біомаси хвойних деревних видів, які дещо поступаються перед м’яколистяними.

У ході опрацювання методологічних основ оцінювання енергетичного потенціалу деревної біомаси лісів її диференційовано на три основні складові частини: дров’яна стовбурова деревина, лісові деревні відходи та лісопромислові деревні відходи. Для цих складників запропоновано математичні залежності для оцінювання їх загального енергетичного потенціалу.

Для забезпечення оцінювання енергетичного потенціалу деревної біомаси на засадах сталого лісоуправління, запропоновано виокремити п’ять його типів: теоретично можливий, технічно доступний, екологічно безпечний, економічно доцільний та соціально зумовлений. Це дасть змогу гармонійно поєднувати питання екологічної безпеки та економічного розвитку регіонів, а також враховувати соціальні особливості життя місцевих громад.
GIS-based prediction of the foliage browsing insects' outbreaks in the pine stands of the SE "Kreminske FHE"
Authors: Meshkova V. , Borysenko O.
Published: April 2018

To improve the detection and prevention of foliage browsing insects' outbreaks it is very important to reveal the forest plots, which are the most favorable for these pests.

The aim of this research was to predict using GIS technologies the spatial dynamics of foliage browsing insects' outbreaks in the pine stands of the State Enterprise "Kreminske FHE" (Luhansk region).

Forest inventory databases of Production Association "Ukrderzhlisproekt" were analyzed for the SE "Kreminske FHE" as of 2001 and 2011. Rating of forest plots preferences for common pine sawfly (Diprion pini L.) and European pine sawfly (Neodiprion sertifer Geoffr.) considered the type of forest site conditions, age of stand, density of stocking, and the part of pine in the stand composition. If forest plot bordered with clear-cut, then 1 point was added to the general score of the threat.

It was shown, that the area with high threat of European pine sawfly and common pine sawfly outbreaks for 2001–2011 increased in the forest fund of the SE "Kreminske FHE" by 702.8 and 2004.2 hectares respectively. The part of foci area made up 27.5 and 32 % from forest fund area, 42.5 % and 49.5 % from pine stands area for European pine sawfly and common pine sawfly respectively.

The areas of pine sawflies foci increased mainly in result of decrease the stocking density of pine stands and increase the number of plots which border with clear-cuts.

The survey for pine sawflies is recommended to carry out first of all in the plots with high threat of foci appearance.

Este artículo analiza la historia institucional de la Escuela de Oficios Domésticos y el Asilo San José para niños desamparados, dos instituciones creadas por la Beneficencia de Cundinamarca para la atención y educación de la niñez en orfandad y abandono. Este análisis se realiza a partir de los informes de protección infantil dados a la Junta General de Beneficencia por parte del secretario de Asistencia Social y de los directores científicos y administrativos de estos establecimientos durante los años 1938, 1939, 1944 y 1946. El interés se centra en analizar, describir y contextualizar el funcionamiento y la vida cotidiana de estas instituciones.
Intervención del sufrimiento, relaciones y estrés traumático secundario en trabajadores sociales
Authors: Casillas Cárdenas Olga Lidia
Published: April 2018

Este artículo plantea el proceso de intervención como un entramado de relaciones que suscita un intercambio simbólico entre los sujetos atendidos y el trabajador social, presentándose estrés traumático secundario. Se demuestra que las relaciones simbólicas por reciprocidad y donación guardan correspondencia con la problemática social, impacto emocional y vulnerabilidad del sujeto atendido, donde aparecen experiencias de sobreimplicación empática y pérdida de objetivación profesional, deteriorando la salud de los profesionales. Se plantea el modelo de intervención relacional como propuesta para la intervención y gestión de proyectos de prevención en el autocuidado de los profesionales que brindan apoyo emocional.
“Uma crônica sobre os fatos do momento”: o jogo do bicho nas poesias de monólogos interpretados e publicados no Rio de Janeiro entre 1892 e 1894
Authors: De Souza Silvia Cristina Martins
Published: April 2018

De acordo com o historiador Robert Darnton, em sociedades do passado com baixo índice de letramento, as poesias criaram redes de comunicação que funcionavam como crônicas do cotidiano. Partindo deste pressuposto, neste artigo são analisadas as poesias de dois monólogos interpretados e publicados no Rio de Janeiro entre 1892 e 1894, cujo tema é o jogo do bicho. Nosso objetivo é compreender de que forma seus autores delas se utilizaram para inserirem-se num debate mais amplo de crítica ao processo de modernização pelo qual passou o Rio de Janeiro em fins do século XIX, no qual se assistiu à criminalização de certas práticas populares, dentre elas a do jogo do bicho.
Migrantes e fantasmas: imagens e figuras de Benjamin Constant
Authors: Lopes Marcos Felipe de Brum
Published: April 2018

Após o falecimento de Benjamin Constant, em 1891, sua imagem de Fundador da República foi fabricada por parte das elites política e, sobretudo, pelos positivistas brasileiros. Essa imagem heroica materializou-se em figuras que migram de suporte para suporte, em diferentes formatos e tamanhos, do privado ao público. Este texto busca analisar os significados históricos desse processo através do mapeamento das trajetórias das figuras, suas migrações, ressignificações e limites. Defende-se a ideia de que o republicanismo positivista do final do século XIX buscou gerar um observador-cidadão, um indivíduo da crença em imagens seculares e heroicas. Para isso, instrumentalizou a imagem de Benjamin Constant, projetando-o, através de sua morte, no espaço público. Assim, suas figuras são reproduzidas e circulam na imprensa, em monumentos, nas belas artes e no museu que, até hoje, preserva seus documentos e promove sua biografia. Ao final, avalia-se a importância e os limites da retomada da discussão em torno da mobilização de imagens e figuras nacionais em tempos de crise política.
Determinants of total factor productivity in Visegrad Group Nuts-2 regions
Authors: Danska-Borsiak Barbara
Published: April 2018

This article attempts to estimate the total factor productivity (TFP) for 35 NUTS-2 regions of the Visegrad Group countries and to identify its determinants. The TFP values are estimated on the basis of the Cobb-Douglas production function, with the assumption of regional differences in productivity. The parameters of the productivity function were analysed with panel data, using a fixed effects model.

There are many economic variables that influence the TFP level. Some of them are highly correlated, and therefore the factor analysis was applied to extract the common factors – the latent variables that capture the common variance among those observed variables that have similar patterns of responses. This statistical procedure uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. Each component is interpreted using the contributions of variables to the respective component.

I estimated a dynamic panel data model describing TFP formation by regions. An attempt was made to incorporate the common factors among the model’s explanatory variables. One of them, representing the effects of research activity, proved to be significant.
Rompendo a superfície das formas para adentrar em seu conteúdo: uma proposta pedagógica da Secretaria Municipal de Educação de Curitiba para um ensino religioso voltado para a diversidade
Authors: Jaluska Taciane
Published: April 2018

Atualmente há muita discussão acadêmica a respeito da criação de novos recursos e estratégias para inserir o componente curricular Ensino Religioso em um modelo de educação transformadora. Nesse sentido, a presente pesquisa tem como objetivo apresentar, por meio de uma pesquisa qualitativa-descritiva, as novas propostas pedagógicas da Secretaria Municipal de Curitiba visando uma política para um ensino religioso voltado para a diversidade utilizando-se da arte e dos espaços sagrados para a geração de conhecimento próprio. Os resultados da pesquisa apontam que as visitas permitem não apenas conhecer outras realidades, mas perceber e valorizar a diversidade cultural brasileira, pois a cidadania só se constrói com o reconhecimento e respeito pelas muitas formas de se viver e de se pensar o mundo.
O conto Adão e Eva, de Machado de Assis, numa correlação com a definição de Paul Tillich da Bíblia
Authors: Fuchigami Ivna Maia
Published: April 2018

O presente artigo tem por objeto apontar as possíveis aproximações entre o conto machadiano, Adão e Eva, com o pensamento tillichiano sobre sua definição da Bíblia. Machado de Assis, considerado inadvertidamente como um cético radical ou uma pessoa avessa à Religião, desenvolve suas reflexões religiosas ora de forma explícita ora de forma implícita. Representando artisticamente sua cosmovisão, o escritor extrai do cotidiano temas banais para refletirmos teologicamente, sem colocar deliberadamente as questões em termos propriamente religiosos, mas criando espaços vazios que levam a uma relação texto-leitor em que este é estimulado a interagir com o texto e a fazer pontes entre o dito e o não dito. O teológico em Machado de Assis não se sobrepõe ao literário, mas ambos se expressam de forma literária.Palavras-chave : Machado de Assis; - Paul Tillich; Literatura; Teologia; Religião; Bíblia.
O meu itinerário com o pensamento de Paul Tillich
Authors: Higuet Etienne Alfred
Published: April 2018

Escrito em vista de uma Aula Magna, quando se encerrava um ciclo de vida acadêmica, o texto é um ensaio de autobiografia intelectual, dedicado à convivência do autor com o pensamento de Paul Tillich durante mais de cinquenta anos. Privilegiou-se o pensamento político, em relação com a perspectiva histórica e escatológica, e a análise religiosa da cultura, colocando em segundo plano a reflexão epistemológica e a concepção de Deus. Todos os exemplos foram tirados de textos interpretativos do autor, instaurando quase sempre um diálogo com diversos aspectos da cultura contemporânea, principalmente brasileira. Nas considerações finais foram lembrados os cuidados a serem tomados na atualização de um autor de referência, num tempo e num ambiente diferentes dos seus.
Escola e programa na educação integral: abordagens e singularidades
Authors: Ostler Denise De Almeida
Published: April 2018

O presente artigo traz como tema a “educação integral”, pautando-se em uma discussão sobre as nomenclaturas “escola de tempo integral” e “programa ensino integral” e tendo por objetivo discutir os seus aspectos peculiares e diversidades, bem como refletir a respeito das singularidades e divergências apontadas na construção de uma proposta de “escola de tempo integral”, implantada pela Secretaria de Estado da Educação do Estado de São Paulo, em 2006, e o “programa ensino integral”, efetivado no ano de 2012, em São Paulo, pela mesma Secretaria, uma vez que ambas as propostas contemplam a educação integral. As abordagens aqui expostas fazem parte de um trabalho de pesquisa de doutorado, a partir do estudo desenvolvido sob o título: “O impacto da implantação do programa ensino integral no atendimento a alunos com deficiência: desdobramentos em duas escolas públicas da Baixada Santista”. Para tanto, recorremos a autores como: Ribeiro (1988); Paro (1988); Teixeira (1999)[eg1] ; Guará (2007); Padilha (2010)[eg2] , entre outros, como também à legislação que norteia a “educação integral”. Considerando a importância da “educação integral” para a formação global do indivíduo, cabe-nos não só refletir acerca das diferenças exibidas entre os modelos de ensino, da “escola de tempo integral” e o do “programa ensino integral”, mas salientar ser desnecessária a existência diferenciada de ambas as propostas. [eg1]VEJA A INTRODUÇÃO, POR FAVOR. [eg2]DATAS, É ISSO MESMO?
Presentation of the Dossier

We are pleased to offer our readers a brief about Contributions of the archaeological research and literary approaches of Bible, an effort to honor our commitment to scientific theological production, in this case engaging a science whose unique contribution has enriched and continues to enrich our knowledge of Biblical lands and times, providing us with important comparative material to our own times and circumstances. For this reason, the article chosen to open these considerations is “Brief history of biblical archeology: contribution and american criticism”, by Fábio Augusto Darius and Elder Hosokawa, in which these researchers show the affinities of Biblical archaeology with archaeological science in general, and devote themselves to the ambitious goal of relating, even if briefly, the main names and events of Biblical archaeology from its origin to the present, as well as present important aspects of the American contribution to the research, dissemination, and criticism of Biblical archaeology.

Published: April 2018

Este estudo teve como objetivo principal identificar os fatores que compõem as competências de marketing no varejo. A pesquisa, de natureza descritiva e quantitativa, utilizou como instrumento para a coleta de dados um questionário estruturado, que foi aplicado junto a 199 gestores varejistas pertencentes ao mercado varejista de produtos e serviços. De maneira geral, infere-se que os gestores varejistas consideram a imagem da loja e a qualidade do produto/serviço como sendo as principais competências de marketing de suas empresas, o que resulta em uma atenção efetiva com a imagem da empresa. Por fim, identificou-se quatro fatores que sistematizaram as competências de marketing no varejo: orientação para o mercado, capacidades internas, ambiente de negócios e estrutura/processos. Como contribuições teóricas, destacam-se o agrupamento dos vinte atributos das competências de marketing em quatro fatores e o não analisar especificamente o setor supermercadista. Na prática, estes quatro fatores podem ser utilizados pelos gestores varejistas para definir seus novos planos de marketing e novos investimentos em treinamento e desenvolvimento.

Impact of an Institution-Wide Mentoring Program on a Single-Class Cohort of Pediatric Residents

Published: April 2018

This article was migrated. The article was not marked as recommended. Background: Formal mentorship programs have been shown to improve knowledge and clinical skills acquisition, enhance efficiency, and increase research interest. However, there are few detailed reports of mentoring for pediatric residents specifically. Objective: To describe a formal, institution-wide and longitudinal resident mentoring program and to assess resident perceptions of their satisfaction with their primary (program-matched) mentor and their mentoring needs over time. Methods: The program surveyed all residents annually about their experience (n = 108). We administered an additional survey to a selected class cohort in their 3rd year to assess perceptions of mentor assistance in specific domains. All survey data was de-identified and we used descriptive statistics. Results: The selected class cohort consisted of 36 total residents, 30 of which were categorical. The survey response rate for categorical residents each of the three years was ≥ 90%. The response rate for the additional survey sent in the 3rd year of residency was 57% (17/30). Most residents desired to continue with their assigned mentor throughout residency. Mentorship domains that seemed most important to pediatric residents throughout training included: clinical skills, guidance with scholarly projects, & career planning. Later in training, job search skills, negotiation skills and wellness were seen as important mentorship needs. However, most residents perceived having little active assistance from their mentor related to their scholarly work. Conclusions: An institutional mentorship program with careful formal mentor-mentee matching can be a successful strategy to initiate long-term 1:1 mentor relationships throughout residency training. As mentoring needs change across training years, mentoring programs should consider tailoring mentoring priorities and training to match needs associated with the year of training, in addition to the specific needs of the individual resident.
