Practical private-key fully homomorphic encryption in rings
Authors: Gribov Alexey , Kahrobaei Delaram , Shpilrain Vladimir
Published: April 2018

We describe a practical fully homomorphic encryption (FHE) scheme based on homomorphisms between rings and show that it enables very efficient computation on encrypted data.
Our encryption though is private-key; public information is only used to operate on encrypted data without decrypting it.
Still, we show that our method allows for a third party search on encrypted data.
Influence of veneer thickness, mat formation and resin content on some properties of novel poplar scrimbers
Authors: Zhang Yahui , Qi Yue , Huang Yuxiang , Yu Yanglun , Liang Yanjun , Yu Wenji
Published: April 2018

Thick poplar veneers (4–8 mm) have been finely fluffed to manufacture novel scrimbers by two paving ways, namely by random and laminated mat formations. The following properties of the scrimbers were evaluated: modulus of rupture (MOR) via static bending, modulus of elasticity (MOE), compression strength (CS), shear strength (SS), water absorption rate, thickness swelling rate (TSR) and width swelling rate. The results show that utilization of fluffed thicker veneers reduced the mechanical properties to a certain extent. The TSR of the scrimber was first improved and then weakened by increasing the thickness of the veneers. The scrimber prepared from 6-mm-thick veneers showed the best waterproof performance. The random and laminated mat formations affected the surface texture significantly but the mechanical properties and dimensional stability to a lesser extent. With increasing resin content, the waterproof performance of the scrimbers was improved, which was not otherwise expected. The mechanical properties remained essentially unchanged except for the shear strength.
Numerical Simulation for Shale Gas Flow in Complex Fracture System of Fractured Horizontal Well
Authors: Yuan Yingzhong , Yan Wende , Chen Fengbo , Li Jiqiang , Xiao Qianhua , Huang Xiaoliang
Published: April 2018

Complex fracture systems including natural fractures and hydraulic fractures exist in shale gas reservoir with fractured horizontal well development. The flow of shale gas is a multi-scale flow process from microscopic nanometer pores to macroscopic large fractures. Due to the complexity of seepage mechanism and fracture parameters, it is difficult to realize fine numerical simulation for fractured horizontal wells in shale gas reservoirs. Mechanisms of adsorption–desorption on the surface of shale pores, slippage and Knudsen diffusion in the nanometer pores, Darcy and non-Darcy seepage in the matrix block and fractures are considered comprehensively in this paper. Through fine description of the complex fracture systems after horizontal well fracturing in shale gas reservoir, the problems of conventional corner point grids which are inflexible, directional, difficult to geometrically discretize arbitrarily oriented fractures are overcome. Discrete fracture network model based on unstructured perpendicular bisection grids is built in the numerical simulation. The results indicate that the discrete fracture network model can accurately describe fracture parameters including length, azimuth and density, and that the influences of fracture parameters on development effect of fractured horizontal well can be finely simulated. Cumulative production rate of shale gas is positively related to fracture half-length, fracture segments and fracture conductivity. When total fracture length is constant, fracturing effect is better if single fracture half-length or penetration ratio is relatively large and fracturing segments are moderate. Research results provide theoretical support for optimal design of fractured horizontal well in shale gas reservoir.
Assyrians Abroad: Expanding Borders Through Mobile Identities in the Middle Bronze Age
Authors: Highcock Nancy
Published: April 2018

Recent work by both archaeologists and Assyriologists has characterized the main Assyrian settlement at Kaneš/Kültepe not as “colony” at all but as a place in which Assyrians fully integrated themselves into Anatolian society to create a hybridized community or “middle ground.” This paper builds upon their work by examining the ways in which Assyrians participated in such an intercultural society whilst still maintaining the bounded social category of “Assyrian.” Through the reconstruction of their civic institutions and social traditions abroad, Assyrian merchants were able to expand their mental topography of what constituted “Assyrian-ness” from northern Mesopotamia across central Anatolia. This phenomenon is framed within wider discussions of mobile societies and the Old Assyrian textual record to illustrate that a community identity founded upon the mother city of Assur and its cultural conventions continued to thrive across various political and cultural borders. Treaties and letters demonstrate that these borders were well defined and maintained by the Assyrians themselves, but concurrently, that the driving forces behind a trader’s life on the road also meant for such borders to be expanded and reconstituted. Analyzing the Old Assyrian mercantile phenomenon through the vector of mobility enables us to better understand the ways in which the Old Assyrian merchants maintained a cohesive social identity and bounded community whilst working and living in “foreign” territories. Mobility is not an inherently disintegrating force, but shape the common cultural and political institutions which act as fibers binding communities together across great distances.
Role of atrial natriuretic peptide in controlling diabetic nephropathy in rats
Authors: Singh Lakhwinder , Arya Atul , Gupta Sumeet
Published: April 2018

Background

Diabetes is a downregulator of atrial natriuretic peptide (ANP), resulting in reduced nitric oxide level and low expression of endothelial nitric oxide synthase by which nitric oxide level get reduced. In the present study, we examined the role of ANP in reduced nitric oxide level, which may be responsible in controlling diabetic nephropathy in rats.

Methods

Serum nitrite/nitrate ratio, blood urea nitrogen, protein in urine, urinary output, serum creatinine, serum cholesterol, kidney weight, kidney hypertrophy, renal cortical collagen content, thiobarbituric acid level, and antioxidant enzymatic activities were assessed.

Results

Treatment with lisinopril (1 mg/kg) significantly attenuated diabetes-induced elevated glucose level, cholesterol level, and protein in urine concentration. Whereas ANP at low dose (5 μg/kg) has no effect on elevated markers of diabetic nephropathy, treatment with intermediate (10 μg/kg) and high-dose ANP (20 μg/kg) significantly attenuated the diabetes-induced increased blood urea nitrogen, protein in urine, urinary output, creatinine, cholesterol, kidney weight, kidney hypertrophy, renal collagen content, and thiobarbituric acid level and reduced endogenous antioxidant enzymatic activities. High dose of ANP was more effective in attenuating the diabetes-induced nephropathy, renal oxidative stress, and antioxidant enzyme activity as compared with the treatment with low-dose ANP (5 μg/kg), intermediate-dose ANP (10 μg/kg), or lisinopril (1 mg/kg, employed as standard agent). Administration of erythro-9-(2-hydroxy-3-nonyl)adenine, a phosphodiesterase-2 inhibitor (3 mg/kg), in combination with high-dose ANP significantly attenuated high-dose ANP induced ameliorative effects in diabetic nephropathy.

Conclusions

Taken together, these results indicate that diabetes-induced oxidative stress and lipid alterations may be responsible for the induction of nephropathy in diabetic rats. ANP at intermediate and high doses have prevented the development of diabetes-induced nephropathy by reducing the cholesterol level, protein in urine concentration, and renal oxidative stress and by increasing the nitrite/nitrate ratio, certainly providing the direct nephroprotective action.

Authors: Tijani Stephanie Abiola , Olaleye Samuel B. , Farombi Ebenezer O.
Published: April 2018

Background

Oxidative stress and free radical-mediated processes have been implicated in the pathogenesis of indomethacin-induced gastric ulcer. This study investigated the ability of the methanol extract of Chasmanthera dependens to protect the gastric mucosal from oxidative damage induced by oral administration of indomethacin in rats.

Methods

The C. dependens stems were chopped into pieces, air-dried, and pulverized into powder. One kilogram of the powder was macerated in 1 L of methanol for 72 h. The mixture was filtered and evaporated using rotatory evaporator to obtain the extract of C. dependens. Adult male rats were divided into eight groups of six animals per group and were pretreated orally with the methanol extract of C. dependens (200, 400, and 800 mg/kg) or cimetidine (CIM), a standard drug (50 mg/kg), for 7 days. Gastric ulcer was induced orally with indomethacin. Ulcerogenic parameters, oxidative stress indices, and histopathological examination of the stomach were assessed to monitor the gastroprotective potential of C. dependens stem.

Results

Indomethacin caused severe gastric mucosa damage and significant reduction in the gastric mucosa antioxidant system with concomitant increase in the level of lipid peroxidation. Pretreatment with the methanol extract of C. dependens or CIM significantly reduced the formation of ulcer at the different doses administered. Similarly, pretreatments with the extract or CIM improved the antioxidant system, decreased acid output, lipid peroxidation, and improved the architecture of the gastric mucosa in ulcerated rats.

Conclusions

The results show the gastroprotective effect of the methanolic extract of C. dependens, which may be attributed to its antioxidant properties.

Published: April 2018

The Rio Grande Valley (RGV) has been impacted by various hurricanes throughout history. While Hurricane evacuation has been studied extensively in other contexts, there is limited systematic research on the warning and response to a large-scale severe weather event in South Texas. This study attempts to understand the evacuation decision-making behavior of Southern residents in the event of a Hurricane making landfall over the Rio Grande Valley. The study uses an online survey questionnaire with 1060 participants: 275 students attending the University of Texas-Rio Grande Valley and the remaining 785 are members of the community. Throughout the course of the study, information was gathered about selected elements: demographic characteristics, living conditions, the following and awareness of authority recommendations, decision maker roles, reasons for not wanting to leave a disaster-prone area facing an emergency, perception of a safe place, and expected help from both, governments and non-governmental organizations (NGOs) during evacuation that could impact residents’ evacuation decision. Findings reveal there are a number of individuals who will remain in their place of residence, even in the deadliest of hurricane Category 5. The study provides complex factors influencing the nature of evacuation decision-making of individuals who are Hispanics living in a unique geographical location of RGV.

Published: April 2018

Diabetes Mellitus (DM) is one of the biggest healthcare and financial problems worldwide. The disease is strongly associated with microvascular and macrovascular complications, causing co-existing diseases like Diabetic Retinopathy, Diabetic Neuropathy and Diabetic Nephropathy. Annual healthcare expenditures for diabetes treatment and complications prevention cost 727 billion USD in year 2017.

Diabetes Mellitus, Diabetic Retinopathy and Diabetic Retinal Neuropathy are closely related diseases - originating from incorrectly controlled glycemia, blood pressure and lipid levels in the course of increasing resistance of the body tissues to insulin.

Irrespectively of thorough programs for Diabetes Mellitus prevention and treatment, Diabetic Retinopathy management requires targeted treatment strategies for both microvasculopathy and retinal neurodegeneration, to delay disease severity course and risk of blindness.

The study and conclusions in this article are based on web-available data and officially published articles related to the diabetes mellitus and associated diseases – Diabetic Retinopathy and Diabetic Retinal Neuropathy. The articles have been reviewed and analyzed to assess mutual relations between the discussed diseases.

Published: April 2018

Introduction. In women with diabetes, the changes that accompany menopause may further diminish glycemic control. Little is known about how hormone replacement therapy (HRT) affects glucose metabolism in diabetes. The aim of this study was to examine whether HbA1C levels are influenced by current HRT among postmenopausal women with type 2 diabetes.

Methods. A total of 40 postmenopausal women with type 2 diabetes were enrolled. All of them fulfilled the criteria of natural menopause, with intact uterus, low estrogen levels (E2) and high follicle-stimulating hormone (FSH) levels. Half of them (20 women) were assigned to take HRT (DM-HRT group). The other half (20 women) were assigned to the control group, those who did not take HRT (DM-non HRT group). HRT consisted of 17 β-estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg. Fasting plasma glycemia, insulinemia and HbA1C were followed in both groups throughout 12 months.

Results. The mean age was 49 years (SD±3,3) and 48,5 (SD±3.1), respectively. HRT was associated with statistically significant decrease in serum fasting glucose, HbA1C and insulinemia levels in the DM-HRT group. There was no significant reduction in glucose levels and HbA1C together with no significant increase in insulinemia levels in the DM non-HRT group throughout 12 months.

Conclusion. HRT was associated with statistically significant decrease of plasma glucose levels and HbA1C level. Larger clinical trials are necessary to understand whether HRT may improve glycemic control in women with diabetes, especially when it is given shortly after entering menopause.

Magnetic transmission gear finite element simulation with iron pole hysteresis
Authors: Filippini Mattia , Alotto Piergiorgio , Glehn Gregor , Hameyer Kay
Published: April 2018

Ferromagnetic poles in a magnetic transmission gear require particular attention during their design process. Usually, during the numerical simulation of these devices the effects of hysteresis for loss estimation are neglected and considered only during post-processing calculations. Since the literature lacks hysteresis models, this paper adopts a homogenized hysteretic model able to include eddy current and hysteresis losses in 2D laminated materials for iron poles. In this article the results related to the hysteresis in a magnetic gear are presented and compared to the non-hysteretic approach.
Mathematical model for thermal and entropy analysis of thermal solar collectors by using Maxwell nanofluids with slip conditions, thermal radiation and variable thermal conductivity
Authors: Aziz Asim , Jamshed Wasim , Aziz Taha
Published: April 2018

In the present research a simplified mathematical model for the solar thermal collectors is considered in the form of non-uniform unsteady stretching surface. The non-Newtonian Maxwell nanofluid model is utilized for the working fluid along with slip and convective boundary conditions and comprehensive analysis of entropy generation in the system is also observed. The effect of thermal radiation and variable thermal conductivity are also included in the present model. The mathematical formulation is carried out through a boundary layer approach and the numerical computations are carried out for Cu-water and TiO2-water nanofluids. Results are presented for the velocity, temperature and entropy generation profiles, skin friction coefficient and Nusselt number. The discussion is concluded on the effect of various governing parameters on the motion, temperature variation, entropy generation, velocity gradient and the rate of heat transfer at the boundary.
Feynman diagrams and rooted maps
Authors: Prunotto Andrea , Alberico Wanda Maria , Czerski Piotr
Published: April 2018

The rooted maps theory, a branch of the theory of homology, is shown to be a powerful tool for investigating the topological properties of Feynman diagrams, related to the single particle propagator in the quantum many-body systems. The numerical correspondence between the number of this class of Feynman diagrams as a function of perturbative order and the number of rooted maps as a function of the number of edges is studied. A graphical procedure to associate Feynman diagrams and rooted maps is then stated. Finally, starting from rooted maps principles, an original definition of the genus of a Feynman diagram, which totally differs from the usual one, is given.

Published: April 2018

In this paper exact solutions corresponding to the rotational flow of a fractional Oldroyd-B fluid, in an annulus, are determined by applying integral transforms. The fluid starts moving aftert= 0+when pipes start rotating about their axis. The final solutions are presented in the form of usual Bessel and hypergeometric functions, true for initial and boundary conditions. The limiting cases for the solutions for ordinary Oldroyd-B, fractional Maxwell and Maxwell and Newtonian fluids are obtained. Moreover, the solution is obtained for the fluid when one pipe is rotating and the other one is at rest. At the end of this paper some characteristics of fluid motion, the effect of the physical parameters on the flow and a correlation between different fluid models are discussed. Finally, graphical representations confirm the above affirmation.
Influence of Temperature on the Volume Change Behavior of Saturated Sand
Authors: Liu Hong , Liu Hanlong , Xiao Yang , McCartney John S.
Published: April 2018

The effect of temperature on the volume change of sand is rarely reported but may be relevant to the performance of energy geostructures. This study involves an investigation of the thermal volume change behavior of saturated, dense sand through a series of temperature-controlled, isotropic hollow cylinder triaxial compression tests. Variables measured during a heating stage include the volume of water expelled from the sand specimen, the temperatures at the top, bottom, and inside of the specimen, and the axial and volumetric strains. The volumes were used along with thermo-elastic relationships for the pore water and soil skeleton to infer the axial and volumetric strains during drained heating. It was observed that the thermally induced axial and volumetric strains were negative, reflecting expansion. The pore water was observed to flow out of the sand specimen during heating, reflecting differential thermal expansion of the pore water and sand particles. The thermal volume changes were observed to be independent of the mean effective stress, as the dense sand specimens were all in normally consolidated conditions. Three linear equations incorporating the effects of temperature on the volume change behavior of dense sand were proposed and match well with the experimental data. The experimental approach proposed in this study can be used in the future to evaluate the role of sand density and stress state on the parameters of these equations.

[only abstract in English; full article and abstract in Lithuanian]

The article discusses mediation in Lithuanian criminal and administrative infringement cases. The challenges of mediation are discussed from the perspective of both the first instance judge and leading scholar in the field of mediation in Lithuania. The article analyzes the practical issues of mediation, questions the legal status of mediation in Lithuanian criminal jurisprudence and shows a good practice of mediation in criminal and administrative infringement cases.Mediation is not the court and does not substitute the court; the final decision is made by the court. Mediation could allow both parties to reach an agreement. However, the victim and the culprit do not always reach for an agreement. It is a beneficial practice in both ways. With the help of a mediator, parties learn how to discuss and hear the other side. It aids in coexisting in non-conflict ways in the future. Foreign experience reveals the most important doubts in the process of mediation that both the victim and the culprit face. The society lacks information on mediation. A high priority should be given for increasing the awareness of the benefits of mediation. Judges represent an authoritative power of the state and should use it in the reconciliation of conflicting parties.Lithuanian criminal justice lacks legislation in the field of mediation; however, mediation is de facto possible if the judge is active. Also, mediators who work at the institutions of probation help to legitimize the institute of mediation.

There has been some great public concern regarding the provision of effective services for delinquent juveniles in order to decrease their untoward behavior and enable them to build further lives without any harm to either themselves or the others. The first results of the effectiveness research of cognitive-behavioral correctional program EQUIP, conducted in United States, where the program was first devised, have shown a great impact of the EQUIP program toward the decrease of delinquent behavior. However, the findings of further investigations in other countries remain controversial.The aim of this study was to measure the impact of the EQUIP program toward the changes of juveniles’ cognitive distortions, social skills and problem behavior at Lithuanian Children Socialization Centers. Quantitative research was conducted to compare the data of the EQUIP and comparison groups before and after the implementation of the EQUIP program. The study involved 124 juveniles (74 males and 50 females) aged 11-17 years. Assuming that the integrity of a correctional program might affect the results of the program’s impact, the following basic components of program integrity (Helmond et al., 2014) where secured while implementing the EQUIP program in Lithuania: 1) Exposure; 2) Adherence; 3) Participant responsiveness; 4) Quality of implementation.The results of the study revealed significant differences of thinking errors, social skills and problem behavior before and after the participation in the EQUIP program, while differences in the abovementioned variables within the comparison group were either absent or insignificant. Based on the results of the study, the intensity of the EQUIP program implementation (5 times per week vs. 4 or less times per week) is an important provision for the increase of the effectiveness of the EQUIP program. Moreover, the age of participants (above 14 years old) is a very important factor to safeguard the changes in cognitive and behavioral variables.It is recommended that further studies on the impact of the EQUIP program are focused on the evaluation of changes of criminal recidivism rates in a long-term perspective as well as criminal attitudes. Moreover, the participation in the EQUIP program should be related to the level of criminal risk, whenever the measure of it is available in Lithuania.

Особливості лісової типології в країнах Альпійсько-Карпатського макрорегіону
Authors: Tretyak P. , Сhernevyy Yu.
Published: April 2018

У загальноєвропейському масштабі тип лісу розуміють як категорію, визначену за складом деревної рослинності та умовами місця росту. Основою лісотипо­ло­гічної класифікації лісової рослинності у гірських країнах Європейського Союзу є природничо-лісова регіоналізація та  рангування типів лісу за висотними ступенями рослинності у горах. Подальша диференціація лісового континууму пов'язується з особливостями геологічного підґрунтя, рівнями родючості ґрунтів, ступенями зволоженості та діапазонами її мінливості. Кожен тип лісу у межах конкретного регіону позначається формулою, що містить послідовний ряд абревіатур наведених категорій, який завершується шифром клімаксового лісового рослинного угруповання. Досягнення лісівничих шкіл сусідніх гірських країн у побудові схем системно-структурної диференціації лісового покриву та класифікацій типів лісу можуть слугувати прототипами, за якими варто було б здійснити комплексне удосконалення лісової типології Українських Карпат.

Проведено екоморфічний аналіз фітоценозів на арені р. Дніпро в межах природ-ного заповідника «Дніпровсько-Орільський». Оцінено екологічну специфіку фітоце-нозів, що є основою для розробки екологічно обґрунтованого їх збереження. Визначе-но, що у фітоценозах значну частину складають багаторічники. Проаналізовано це-номорфічну, трофоморфічну та гігроморфічну структуру фітоценозів. Різноманітнішляхи рознесення насіння призводять до формування значного потенціалу дистри-буції рослин у межах та за межами досліджуваного полігону.
Екологізація економіки – основа формування та реалізації концепції сталого розвитку в прикордонних регіонах України і суміжних держав
Authors: Dubovych I.
Published: April 2018

Розглянуто сучасні еколого-економічні проблеми транскордонного співробітництва України і суміжних країн. Проалізовано теоретико-методологічні та практичні основи, спрямовані на реалізацію екологізації економіки та сталого розвитку в прикордонних регіонах України і суміжних країн. Розглянуто важливість і актуальність побудови ефективного транскордонного еколого-економічного співробітництва в Україні. Акцентовано на тому, що в найближчому майбутньому на прилеглих до кордону територіях України і суміжних держав небезпечні тенденції у сфері деградації екологічної системи будуть поглиблюватись. Зазначено, що перехід до сталого розвитку в прикордонних регіонах України та сусідніх країн неможливий без екологізації економіки та екологізації освіти з метою підготовки фахівців для сталого розвитку.
Властивості личкованих деревинно-полімерних матеріалів плоского способу пресування
Authors: Lyutyy P. , Веkhta P. , Ortynska G.
Published: April 2018

Досліджено процес личкування деревинно-полімерних матеріалів (ДПМ) плоского способу пресування. Личкування ДПМ здійснено одночасно з їх пресуванням. Для личкування використано декоративний ламінат високого тиску (HPL) товщиною 0,5 мм. Як клей для приклеювання HPL використано поліетиленову (ПЕ) плівку або вторинний поліетилен низької щільності (ВПЕ). Для порівняння виготовлено личковані ДПМ без використання клею для приклеювання HPL. Встановлено, що тип клею не має істотного впливу на механічні показники ДПМ. Межа міцності під час статичного згинання у разі використання ВПЕ зростає на 14%, а у разі використання ПЕ плівки – на 24%, порівняно із личкованими ДПМ без використання клею для приклеювання HPL. Аналогічні залежності спостережено і для модуля пружності під час статичного згинання. Тип клею для приклеювання HPL також не має визначального впливу на межу міцності під час розтягування перпендикулярно до площини плити. Набрякання за товщиною значно зменшується із використанням клею, особливо це проявляється під час занурення взірців у воду на 24 год. У разі використання ПЕ плівки та ВПЕ отримано практично однакові результати набрякання за товщиною, як за 2, так і за 24 год занурення.
Економічні наслідки всихання ялинників Українських Карпат
Authors: Shparyk Y.
Published: April 2018

Аналіз результатів стаціонарних досліджень 19-ти деревостанів в основних типах лісу ялинників Українських Карпат дав змогу оцінити економічні наслідки їх всихання. Поточні (в найближчі 10 років) наслідки можуть бути як позитивними, так і негативними: збільшення доходу від зростання обсягів заготівлі деревини; зменшення доходу від втрати вар­тості деревини ялини та від зниження повноти ялинників. Довготермінові наслідки передбачають зменшення доходу від втрати вартості деревини внаслідок зміни породного складу ялинових лісостанів на букові; втрати деревини внаслідок зменшення її приросту; збільшення обороту рубки.

Дохід від заготівлі додаткового обсягу деревини внаслідок всихання ялини визначається інтенсивністю всихання та розподілом ялинників за класами віку і досягає максимуму в умовах вологої чистої сусмеречини (7,45 тис. грн/га за рік) з середнім його значенням 5,35 тис. грн/га за рік. Запізніле проведення санітарно-оздоровчих заходів зменшує цей дохід на 30-40%. Поточні збитки від зменшення радіального приросту стовбурів ялини і зменшення повноти ялинників за типами лісу оцінено від 7,91 (С3-См) до 16,24 (С3-бк-яцСм) тис. грн/га за рік.

Довготермінові наслідки всихання помітно менші від поточних з від’ємним балансом за основними типами лісу, з максимумом в умовах вологої буково-смерекової суяличини (0,73 тис. грн/га за рік) та середнім значенням збитків на рівні 0,23 тис. грн/га за рік. З їх урахуванням середній розмір збитків від всихання ялини в основних типах лісу регіону може досягнути 7 тис. грн/га за рік.
The effects of use values, amenities and payments for public goods on farmland prices: Evidence from Poland
Authors: Czyzewski Bazyli , Trojanek Radoslaw , Matuszczak Anna
Published: April 2018

The article contributes to the debate on how land prices are affected by production values, by farming subsidies and by environmental amenities. The authors carried out a comprehensive review of the literature on the actual determinants of land value and made an attempt to classify different approaches to this matter. Then they performed an empirical case study of the drivers of agricultural land values in a leading agricultural region of Poland. The aim of the study is to establish how the use values of land, amenities and policy payments contribute to land values in the Single Area Payment Scheme (SAPS), which operates in Poland. The study is based on a sample of 653 transactions during the years 2010–2013. A hierarchical regression (ML-IGLS method) was used, where the unobserved heterogeneity is attributed to the location-specific factors at different levels of analysis. Results indicate that the policy payments for public goods decapitalise the value of land, whereas the environmental amenities have a relatively strong influence on farmland prices.
Hera and Juno in the Argonautica
Authors: Radová Irena
Published: April 2018

The article deals with the role of the Greek goddess Hera and her Roman counterpart, Iuno, in the poetic treatments of the myth of Argonauts. The focus is put especially on Iuno’s character development in Valerius Flaccus’ adaptation of the myth. Iuno’s character in this work has already been discussed by Werner Schubert in his fundamental study (1991), in which he pointed out the remarkable approximation of Iunofabulosaand Iunocivilis. Referring to this study, the article emphasizes rather the literary development of Iuno’s character. It is shown that Valerius Flaccus portrays the highest goddess not only as a peculiar helper (socia), as suggested by Schubert, but also as a permanent participant in an intertextual dialogue with the epic poems of Homer and Apollonius Rhodius. Valerius Flaccus’ aim here is to invert his literary predecessors’ accounts in a subtle and witted way (as Debra Hershkowitz has already presented).
Fleeting Emotional Unity of French Protestantism in Ephemeral Spaces
Authors: Zwilling Anne-Laure
Published: April 2018

National gatherings are regularly held in French Protestantism. Particularly, the recent years have witnessed the establishment of large national festive gatherings. These meetings aim at bringing people together. For the sake of togetheness as well as for theological reasons, the organizers usually seek to uphold all the trends and currents of French Protestantism. The latter remains, however, characterized by its extreme diversity, which has been increasing in the recent past. During the meetings, these gatherings create some kind of a united Protestant church. It seems, however, that the ephemeral nature of the event is, in fact, what allows unity. The religious unity of French Protestantism has a very paradoxical dimension.

A análise se dá a partir dos documentos legislativos produzidos na Câmara Municipal de Curitiba. Discute questões acerca de patrimonialismo, conservadorismo e fundamentalismo.
Aproximações e diferenciações da Filosofia da Religião e da Teologia em Paul Tillich
Authors: Moraes Junior Manoel Ribeiro de , Py Fábio
Published: April 2018

Neste texto, pretendemos observar partes da trajetória intelectual do teólogo alemão-luterano Paul Tillich, principalmente, as que destacam a relação e diferenciação entre a filosofia da religião e da teologia. Para tanto, devemos nos deter no fragmento de “Tema e Método da Filosofia da Religião”, que é uma parte integrante do livro “Filosofia da Religião” de Paul Tillich (1973), quando percebe a religião acima do pensamento moderno e iluminista, demonstrando que a filosofia deve abrir mão de designar à religião os seus interesses a fim de entendê-la na sua manifestação na cultura. Também, se visa esclarecer a relação entre a Filosofia da Religião e a Metafísica, evitando o mal-entendido que se reconhece no temo “metafísica”, pois, sobre metafísica não se deve entender algo como uma ciência sobre os fundamentos últimos do mundo ôntico, mas como a atividade intelectual independente. Para designar mais ainda a idéia de metafísica, Tillich afirma que este saber não pode ser imaginado vinculado ao lado ou acima das ciências, mas de forma independente.
Conservadorismo x atuação social entre grupos excluídos: observação de algumas relações entre pressupostos teóricos e práticos em três igrejas pentecostais
Authors: Gomes Ronaldo Martins
Published: April 2018

Neste artigo reflete-se sobre a experiência de uma investigação de campo realizada pelo autor, que consistiu na visita e observações de três igrejas pentecostais, cinco cultos em cada uma delas, para compreender e analisar como são os serviços religiosos e alguma de suas particularidades, após se apresentar a função social da religião e o desenvolvimento do pentecostalismo brasileiro. A metodologia utilizada foi uma pequena revisão bibliográfica sobre o tema religião e suas funções sociais, e a pesquisa observacional. Como resultado, evidencia-se uma compreensão sociológica do papel da religião na vida social, sobretudo em um momento marcado pela defesa intransigente de bandeiras conservadoras na política nacional.
A frente parlamentar evangélica e os direitos sexuais e reprodutivos: ameaças à laicidade no Brasil contemporâneo
Authors: Dias Tainah Biela
Published: April 2018

A recente visibilidade da atuação política de parlamentares que compõem a Frente Parlamentar Evangélica (FPE) no Congresso Nacional têm sido fundamental para a compreensão de como se constrói a laicidade brasileira na contemporaneidade, sobretudo a partir do pleito eleitoral de 2010 e especificamente por conta de seu combate à ampliação dos direitos sexuais e reprodutivos. Tendo isto em vista, o intuito deste artigo é demonstrar como as questões de gênero são centrais nos debates sobre laicidade no Brasil, na medida em que entendemos que o respeito à laicidade é fundamental para o aprofundamento da democracia e para a garantia dos direitos das chamadas minorias sexuais e de gênero.
Variação do custo da cesta básica no município de Taboão da Serra/SP
Authors: Bremer Keila Hirle , Santos João Almeida
Published: April 2018

O DIEESE – Departamento Intersindical de Estatística e Estudos Socioeconômicos divulga mensalmente o custo da cesta básica referente a todas as capitais do país. Em algumas cidades que não são abrangidas pela pesquisa, algumas Instituições de ensino, tanto públicas como privadas, realizam a pesquisa e divulgam o resultado.  Como o município de Taboão da Serra, localizado na região metropolitana de São Paulo, não possui esses dados divulgados, o presente artigo teve como objetivo identificar o custo mensal e médio da cesta básica e verificar a variação de preços de cada produto que compõe a cesta no município de Taboão da Serra em São Paulo. Partindo de uma lista com as quantidades e os produtos definidos pelo Decreto Lei 399 de 1938 e algumas atualizações, no período de janeiro a junho de 2016 foram pesquisados sete estabelecimentos comerciais e aplicado questionário para um grupo de universitários, com o objetivo de identificar quais produtos são mais consumidos.  A metodologia da pesquisa envolve a bibliográfica – para definir os principais conceitos e estado em que o tema se encontra; pesquisa de campo – visita aos pontos de vendas escolhidos para levantar os preços dos produtos e pesquisa quantitativa apenas para destacar os valores em tabelas e gráfico para facilitar a análise e interpretação dos resultados. Um dos resultados aponta que no período de janeiro a junho de 2016 o custo mensal médio da cesta básica em Taboão da Serra/SP foi inferior ao custo divulgado para a cidade de São Paulo no mesmo período pelo DIEESE.
