Eucalyptus camaldulensis has potential for timber, energy, pulp and cellulose production in Brazil due to its ability to adapt to a variety of environmental conditions. The use of improved seeds, selected for economic growth traits, is necessary to increase productivity of commercial stands. Seed seedlings orchards (SSO) are one option for improved seed production. However, pollen contamination from unimproved populations, as well as non-random mating in the SSO, can decrease the predicted genetic gains in selected populations. Thus, we investigate the mating system, pollen flow and dispersal patterns in an E. camaldulensis SSO and progeny test (PT), established with seedlings collected in the SSO, using seven microsatellite loci. All trees in the SSO were mapped, sampled, and genotyped. For the PT, we sampled, genotyped, and measured the total height of seedlings from 25 families. We detected 10 % inbreeding in the PT, resulting mainly from selfing. Furthermore, we found a correlated mating rate of 18.5 % in the SSO, indicating that within the PT there are some full-sibs. Using paternity analysis, we found 14.7 % pollen contamination and a pattern of pollen dispersal between near neighbor trees in the SSO. We found 9.5 % of inbreeding depression for seedlings height. Due to pollen contamination and nonrandom mating in the SSO, the actual genetic gains for growth traits in the PT are probably lower than the predicted genetic gains. We discuss some management strategies in the SSO that can be used to increase genetic gains in commercial reforestation established using seeds collected from the SSO
Large deformation finite element analysis of undrained pile installation
Authors: Konkol Jakub , Bałachowski Lech
Published: November 2016

In this paper, a numerical undrained analysis of pile jacking into the subsoil using Abaqus software suit has been presented. Two different approaches, including traditional Finite Element Method (FEM) and Arbitrary Lagrangian–Eulerian (ALE) formulation, were tested. In the first method, the soil was modelled as a two-phase medium and effective stress analysis was performed. In the second one (ALE), a single-phase medium was assumed and total stress analysis was carried out. The fitting between effective stress parameters and total stress parameters has been presented and both solutions have been compared. The results, discussion and verification of numerical analyzes have been introduced. Possible applications and limitations of large deformation modelling techniques have been explained.
Magneto-rotatory compressible couple-stress fluid heated from below in porous medium
Authors: Mehta Chander Bhan
Published: November 2016

The study is aimed at analysing thermal convection in a compressible couple stress fluid in a porous medium in the presence of rotation and magnetic field. After linearizing the relevant equations, the perturbation equations are analysed in terms of normal modes. A dispersion relation governing the effects of rotation, magnetic field, couple stress parameter and medium permeability have been examined. For a stationary convection, the rotation postpones the onset of convection in a couple stress fluid heated from below in a porous medium in the presence of a magnetic field. Whereas, the magnetic field and couple stress postpones and hastens the onset of convection in the presence of rotation and the medium permeability hastens and postpones the onset of convection with conditions on Taylor number. Further the oscillatory modes are introduced due to the presence of rotation and the magnetic field which were non-existent in their absence, and hence the principle of exchange stands valid. The sufficient conditions for nonexistence of over stability are also obtained.
Effect of increasing mining rate on longwall coal mining – Western donbass case study
Authors: Sdvyzhkova Olena , Patyńska Renata
Published: November 2016

This paper presents the problems associated with the rapid change of the rock stress-strain state in terms of increasing the rate of coal mining. Parameters of the roof collapse are determined depending on the rate of a longwall advancing under conditions of poor rocks. Statistical data are processed to obtain a general trend concerning the mining rate impact on the roof collapse. The statistical strength theory is applied to explain the increase in mined-out space and the size of hanging roof behind a coal face. Numerical simulation is carried out to determine a critical size of mined-out space that provokes a roof collapse. The area of yielded rocks is outlined using the criterion developed taking into account the rate of longwall advancing. A general regularity is obtained to determine the roof collapse parameters. The developed technics gives a possibility to predict the moment of general roof collapse at the initial stage of longwalling to prevent the negative effect of the rapid stress redistribution provoking joints propagation and intensive gas release. The estimation of the rock stress-strain state considering the rate of mining operations can be useful for tasks related to a new technology implementation. The statistical strength theory and failure criterion applied together provides adequate planning of mining activities and the assessment of natural hazards.

Published: November 2016

Hip osteoarthritis (OA) is a degenerative, progressive musculoskeletal system disease in adult individuals. Both genders demonstrate a similar prevalence at 11.5% for men and 11.6% for women. During the initial stage of hip OA, conservative treatments may significantly decrease pain, provide functional improvement and enhance health related quality of life (HRQoL).

The aims of the study were to evaluate the quality of life of patients with hip osteoarthritis and to estimate the impact of a comprehensive rehabilitation intervention on their HRQoL.

This was a prospective, observational study of 50 consecutive patients with hip osteoarthritis who were referred to an outpatient rehabilitation intervention. To assess their HRQoL before and after rehabilitation, we used the SF-36 and the Lequesne index for hip OA.

The mean age was 61.7±8.3 years, and 56% of the patients were women. After rehabilitation, the SF-36 RE and RP subscales and the Lequesne pain subscale showed the most significant improvement, although all of the SF-36 and Lequesne domains showed significant improvement. Before rehabilitation, the Lequesne ADL subscale was most correlated with the SF-36 PF subscale (rho=−0.908). After rehabilitation, the total Lequesne score was highly correlated with the SF-36 PF subscale (rho=−0.895). Age, education and the duration of disease were significantly correlated with all of the Lequesne subscales before and after rehabilitation.

This study showed that patients with hip osteoarthritis had a substantially low HRQoL, but all health dimensions showed statistically significant improvements after outpatient rehabilitation intervention.
Vitamin D Deficiency and its Importance - A Global Problem of Today, Realistic or Not?
Authors: Milovanović Olivera Z.
Published: November 2016

Vitamin D, also known as the “sun vitamin” in the literature, has been examined for many years and still arouses researchers’ interest due to the pleiotropic effects achieved in the human body. Because of the influence on mineral homeostasis, the initially observed effects of vitamin D on the prevention and treatment of rickets, have now been extended to a large number of diseases with different aetiologies such as cardiovascular, autoimmune, endocrine, infectious, neurological, malignant and other diseases. Due to the large number of experimental studies in animals and humans, we have exact information about the role of vitamin D in many of these conditions. Reaching an adequate level of 25(OH)D in the human body is a basic requirement for the realization of these effects; 25(OH)D is a metabolic product that reflects the vitamin D status but that does not have any biological activity. The biological activities of vitamin D can occur only after the formation of a second metabolic product, 1,25(OH)2D, in the kidneys. The three main sources of acquiring vitamin D are through food, skin and supplementation. Food is not a rich source of vitamin D; it is clear that the most important influences to achieve an optimal vitamin D status in the human body are vitamin D synthesis at the skin and adequate supplementation intake. An alarming fact is that vitamin D deficiency is detected in an increasing number of people from one day to another in the general world population and that this condition has pandemic dimensions. Introducing the beneficial effects and sources of vitamin D to the general population and to medical experts with adequate supplementation regime can decrease the number of people who are vitamin D deficient.

Published: November 2016

Mining is unsurprisingly considered a high-risk occupation because it involves continuous hard labour under highly demanding and stressful conditions. Many of these work stressors can impair individuals’ well-being in both a physiological and psychological sense. The aims of this study were to assess the prevalence of burnout and depressive symptoms and to evaluate aspects of proactive coping among underground coal miners in Serbia. The study involved 46 male underground coal miners. Burnout was measured with the Copenhagen Burnout Inventory, depression was assessed with the Patient Health Questionnaire-9, and level of proactive coping was measured with the Proactive Coping Inventory. The results showed a low level of burnout syndrome among the underground coal miners (12.46±4.879). Depression was slightly above the minimum (1.2±2.094), and the majority of the participants had no symptoms of depression (93.5%). Overall, the underground coal miners’ ability to proactively cope with work stress was very good (42.17±6.567). This is in contrast to the findings of the few previous international studies and is a good basis for further research using a larger sample in Serbia.

Abuse in younger populations has been an issue of growing concern globally since youth already face various life situations that can heighten the occurrence of depression and anxiety disorders. The aim of this study was to determine the prevalence of physical and psychological abuse and its correlation with depressive and anxiety symptoms among students.

This research was conducted as an epidemiological study of a sample of 1,940 university students using a standardized questionnaire by the World Health Organization. The survey, in addition to questions related to the abuse of youth, also included the Beck Depression Inventory and Beck Anxiety Inventory.

Based on the results of this study, psychological abuse had a prevalence of 17.1%, while the prevalence of physical abuse was approximately 1.8%. Depressive symptoms were significantly related to physical (p<0.001) and psychological abuse (p<0.005), and anxiety symptoms were also significantly related to both physical (p=0.003) and psychological abuse (p<0.005).

The results of this study indicated the importance of the early detection of abuse and depressive and anxiety symptoms among university students, which is essential for mental health promotion and the prevention of mental disorders.

Published: November 2016

Henoch-Schönlein purpura is a type of systemic small vessel vasculitis. The dominant manifestation is the cutaneous component, the illness is self-limiting in nature, and the prognosis and outcome depend mostly on renal manifestations. We analysed the associations among clinical and laboratory parameters with the prognosis and outcome of HSP in children hospitalised at the Paediatrics clinic, Clinical Centre, Kragujevac between January 2011 and January 2012. Children who developed nephritis were older on average and all manifested with arthritis, abdominal complaints, microhaematuria, elevated D-dimer levels in the serum, and significant proteinuria and microalbuminuria (≥ 300 mg/L), and two children had pre-existing allergic conditions. All three children with repeatedly positive proteins in the morning sample urine test had significant proteinuria (≥0,5 g/24 h) and microalbuminuria (≥ 300 mg/L). These children had more bursts of rash and more severe and lasting abdominal pain and arthritis compared to children with normal urine tests. They were therefore treated with glucocorticoids and an angiotensin-converting enzyme inhibitor. The glomerular filtration rate measured by determining creatinine clearance was normal in all patients. These patients were diagnosed with Henoch-Schönlein purpura nephritis, and their condition was regularly monitored. Analysis of this group of patients demonstrated that the average age of 8 years and abdominal complaints were indicative of nephritis development.. Because both of these parameters are easily noted at disease onset, we suggest careful monitoring of disease course in these children.

Published: November 2016

Supracondylar humeral fractures (SCHF) are the most common elbow fractures in children, representing 3% of all paediatric fractures. Treatment options for SCHF in children are based on the Gartland classification. Treatment of non-displaced fractures (type I) is non-operative. Plaster immobilization for 3 to 4 weeks is recommended, depending on the age of the child and fracture healing. Treatments of displaced supracondylar fractures (type II and III) of the humerus in children are still undefined in clinical practice. Because of divided opinions, the aim of this study was to evaluate whether delayed or immediate surgical treatment has an advantage in the treatment of supracondylar fractures in children. This is a prospective – retrospective clinical study. This study included 64 patients from 5 to 15 years old; 47 (73.4%) were boys and 17 (26.6%) were girls. The most common age range (59.4%) in this study was 5-8 years old. All patients were diagnosed with supracondylar fractures at the Institute for Orthopaedic Surgery “Banjica”. We analysed 17 parameters, which were obtained either from direct patient interviews or from their medical history. All patients were divided into two groups with matched characteristics. Group I consisted of 26 patients who had immediate operations. Group II consisted of 38 patients who had delayed operations.

Based on the results of the analysed parameters, consisting primarily of functional results, the absence of subjective symptoms and myositis ossificans one year after surgery suggests that emergency surgical treatment of displaced supracondylar humeral fractures is optimal.

Published: November 2016

Insomnia is a condition of inadequate quality or quantity of sleep that has extremely adverse effects on daytime activities. Th e aim of this study was to compare the quality of life in patients with primary insomnia before and after a 3-week treatment with lorazepam (n=20) and zolpidem (n=21) and to compare the potential differences in dysfunctional beliefs and attitudes regarding patients’ sleep between the two groups. Th e diagnosis of primary insomnia was established using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria, and patients had to complete a specially designed sleep log every day; on scheduled visits, we also administered a Visual Analogue Scale for quality of life and a self-evaluation questionnaire about Dysfunctional Beliefs and Attitudes related to Sleep at the beginning and end of this study. In summary, the examinees in our study had significantly decreased parameters of quality of life, quite lower than expected based on previous findings in this area. However, by the end of the study, quality of life significantly improved with treatment: it improved by approximately 2/3 in the Lorazepam group and more than twice in the Zolpidem group, with a significant difference in favour of Zolpidem (p=0.047). Th is finding is most likely a consequence of its better safety profile and in part its better efficiency in terms of influence on certain domains of sleep itself, as previously discussed. Further specialized studies in this area with larger samples and a more detailed methodology are clearly warranted.

The effect of dehydration on the kinetics of forward electron transfer (ET) has been studied in cyanobacterial photosystem I (PS I) complexes in a trehalose glassy matrix by time-resolved optical and EPR spectroscopies in the 100 fs to 1 ms time domain. The kinetics of the flash-induced absorption changes in the subnanosecond time domain due to primary and secondary charge separation steps were monitored by pump–probe laser spectroscopy with 20-fs low-energy pump pulses centered at 720 nm. The back-reaction kinetics of P700were measured by high-field time-resolved EPR spectroscopy and the forward kinetics ofA1A•−/A1B•−→FX${\rm{A}}_{{\rm{1A}}}^{ \bullet - }/{\rm{A}}_{1{\rm{B}}}^{ \bullet - } \to {{\rm{F}}_{\rm{X}}}$by time-resolved optical spectroscopy at 480 nm. The kinetics of the primary ET reactions to form the primaryP700•+A0•−${\rm{P}}_{700}^{ \bullet + }{\rm{A}}_0^{ \bullet - }$and the secondaryP700•+A1•−${\rm{P}}_{700}^{ \bullet + }{\rm{A}}_1^{ \bullet - }$ion radical pairs were not affected by dehydration in the trehalose matrix, while the yield of theP700•+A1•−${\rm{P}}_{700}^{ \bullet + }{\rm{A}}_1^{ \bullet - }$was decreased by ~20%. Forward ET from the phylloquinone molecules in theA1A•−${\rm{A}}_{1{\rm{A}}}^{ \bullet - }$andA1B•−${\rm{A}}_{1{\rm{B}}}^{ \bullet - }$sites to the iron–sulfur cluster FXslowed from ~220 ns and ~20 ns in solution to ~13 μs and ~80 ns, respectively. However, as shown by EPR spectroscopy, the ~15 μs kinetic phase also contains a small contribution from the recombination betweenA1B•−${\rm{A}}_{1{\rm{B}}}^{ \bullet - }$andP700•+.${\rm{P}}_{700}^{ \bullet + }.$These data reveal that the initial ET reactions from P700to secondary phylloquinone acceptors in the A- and B-branches of cofactors (A1Aand A1B) remain unaffected whereas ET beyond A1Aand A1Bis slowed or prevented by constrained protein dynamics due to the dry trehalose glass matrix.

The local coordination of the manganese in Li[Co0.98Mn0.02]O2 cathode materials for lithium-ion batteries has been investigated by means of a joint XRD and multi-frequency electron paramagnetic resonance (EPR) characterization approach. EPR showed the manganese being in a tetravalent high-spin Mn4+-oxidation state with

The set of spin-Hamiltonian parameters obtained from the multi-frequency EPR analysis with Larmor frequencies ranging between 9.4 and 406 GHz is transformed into structural information by means of the recently introduced Monte-Carlo Newman-superposition modeling. Based on this analysis, the Mn4+ are shown being incorporated for the Co3+-sites, i.e. acting as donor-type functional centers

Furthermore, the results obtained here suggest that the oxygen octahedron about the Mn4+-ion is slightly distorted as compared to the CoO6 octahedron. Concerning the coordination to next-nearest neighbor ions, part of the manganese resides in manganese-rich domains, whereas the for the remaining centers the Co3+-site is randomly occupied with Co/Mn according to the effective stoichiometry of the compound. Finally, a structural stability range emerges from the Newman-modeling that supports the discussed ability of manganese to act as an structure-stabilizing element in layered oxides.
Familial non-medullary thyroid cancer: unraveling the genetic maze
Authors: Peiling Yang Samantha , Ngeow Joanne
Published: November 2016

Familial non-medullary thyroid cancer (FNMTC) constitutes 3–9% of all thyroid cancers. Out of all FNMTC cases, only 5% in the syndromic form has well-studied driver germline mutations. These associated syndromes include Cowden syndrome, familial adenomatous polyposis, Gardner syndrome, Carney complex type 1, Werner syndrome and DICER1 syndrome. It is important for the clinician to recognize these phenotypes so that genetic counseling and testing can be initiated to enable surveillance for associated malignancies and genetic testing of family members. The susceptibility chromosomal loci and genes of 95% of FNMTC cases remain to be characterized. To date, 4 susceptibility genes have been identified (SRGAP1 gene (12q14), TITF-1/NKX2.1 gene (14q13), FOXE1 gene (9q22.33) and HABP2 gene (10q25.3)), out of which only the FOXE1 and the HABP2 genes have been validated by separate study groups. The causal genes located at the other 7 FNMTC-associated chromosomal loci (TCO (19q13.2), fPTC/ PRN (1q21), FTEN (8p23.1-p22), NMTC1 (2q21), MNG1 (14q32), 6q22, 8q24) have yet to be identified. Increasingly, gene regulatory mechanisms (miRNA and enhancer elements) are recognized to affect gene expression and FNMTC tumorigenesis. With newer sequencing technique, along with functional studies, there has been progress in the understanding of the genetic basis of FNMTC. In our review, we summarize the FNMTC studies to date and provide an update on the recently reported susceptibility genes including novel germline SEC23B variant in Cowden syndrome, SRGAP1 gene, FOXE1 gene and HABP2 genes in non-syndromic FNMTC.

Germline mutations in codon 918 of exon 16 of theRETgene (M918T) are classically associated with multiple endocrine neoplasia type 2B (MEN 2B) with highly aggressive medullary thyroid cancer (MTC), pheochromocytoma and a unique phenotype. The objectives of this study are to describe the rare M918VRETmutation discovered in 8 MTC kindreds from Brazil lacking the MEN 2B phenotype classically observed in M918T patients and to investigate the presence of a founder effect for this germline mutation. Eight apparently sporadic MTC cases were diagnosed with the germline M918VRETmutation. Subsequently, their relatives underwent clinical and genetic assessment (n = 113), and M918V was found in 42 of them. Until today, 20/50 M918V carriers underwent thyroidectomy and all presented MTC/C-cell hyperplasia; the remainder carriers are on clinical follow-up. None of the M918V carriers presented clinical features of MEN 2B. Their clinical presentation was heterogeneous, and the age at tumor diagnosis ranged from 24 to 59 years. Lymph node metastases were present in 12/20 patients, and presumable distant metastases in 2/20; in contrast, we observed a carrier of up to 87 years of age without evidence of MTC. Ethnographic fieldwork and haplotype analyses suggested that the founder mutation first settled in that area fifteen generations ago and originated from Portugal. Our study is the first to demonstrate theRETM918V mutation co-segregating in 8 familial MTC kindreds with validated evidence of a founder effect. We suggest that M918V MTC should be clinically considered an American Thyroid Association (ATA) moderate-risk category.

Published: November 2016

In special dietary products for people intolerant to gluten, gluten content is not supposed to exceed the regulatory thresholds. Enzyme-linked immunosorbent assays (ELISAs) are routinely used to quantitate gluten in these products. They measure gliadin/gluten with high specificity and sensitivity, but they have some limitations. Quantitative and qualitative variability of the target proteins among wheat cultivars is a factor that may cause inaccurate results. One of the aims of this work was to characterize the protein composition of five wheat cultivars grown in multiple harvest years and their blends by reversed-phase high-performance liquid chromatography (RP-HPLC). The gliadin/gluten content of these wheat flours was also analysed with two commercial ELISA kits. The effect of differences in protein profiles between the flours from an individual cultivar and the blend of five cultivars, harvest years, as well as processing procedures (dough forming and baking) on the results of two ELISA kits was investigated and their relative magnitude was determined. Among the factors investigated, the differences between flours had the greatest impact on gliadin recoveries.
Problems and causes of marginal nutrient availability in winery wastewater treatment
Authors: Bakos V. , Kiss B. , Jobbágy A.
Published: November 2016

Winery wastewater treatment plants generally face severe nutrient deficiency, and therefore conventional technologies and supplementary nutrient dosing strategies may fail. The purpose of the paper is to show how traditional way of dosing N-source for marginal availability to nutrient deficient influents results in poorly settling activated sludge regardless of the application of aerated or non-aerated selectors. External N-source calculated for marginal availability resulted in nutrient deficiency due to the relatively high yield experienced (0.7 g biomass COD/g substrate COD). In the fully aerated system with overall N-deficiency, rapidly increasing overproduction of extracellular polysaccharide was experienced, leading to SVI (Sludge Volume Index) values up to 600 cm3 g−1. In the system with the non-aerated selector, initial nutrient deficiency could only be detected in the second reactor. Since neither overgrowth of floc-forming GAOs (Glycogen Accumulating Organisms) nor denitrification could be experienced, the non-aerated reactor operated as low-DO (Dissolved Oxygen) basin, attributing to the drastic overgrowth of filamentous bacteria leading to SVI values >1000 cm3 g−1. Since dosing external N-source for marginal availability is likely to cause severe biomass separability problems in activated sludge winery wastewater treatment, either pronounced N-overdosing and pre-denitrification or severe nutrient deficiency and GAO cultivation can rather be recommended.
Applying MICP by denitrification in soils: a process analysis

Published: November 2016

The process of microbially induced carbonate precipitation (MICP) by denitrification was investigated in relation to its potential use as a ground improvement method. Liquid batch experiments indicated that the substrate solution had an optimum carbon–nitrogen ratio of 1·6 and confirmed that combining nitrate reduction and calcium carbonate precipitation leads to an efficient conversion, at which the pH is buffered slightly below 7 and the accumulation of toxic intermediate nitrogen compounds is limited. Sand column experiments confirmed that the volume and distribution of the gas phase strongly depend on the stress conditions. The produced gas volume is inversely related to the pore pressure and can be predicted based on a mass balance analysis, assuming conservation of mass and using theoretical laws of physics. At low pore pressure, the gas formed and accumulated at the top of the column, whereas calcium carbonate precipitation occurred mostly at the bottom near the substrate inlet; an excess amount of gas was produced, which vented from the sand columns and induced cracks in the sand at low confining pressures, which negatively affected the sand-stabilising effect of the calcium carbonate minerals.
Rollover instability of precast girders subjected to wind load
Authors: Lee Jong-Han , Kalkan Ilker , Lee Jong-Jae , Cheung Jin-Hwan
Published: November 2016

The use of longer and deeper precast concrete girders has created concern regarding their rollover instability, particularly during construction. Current design and construction specifications do not provide any specific guidelines that can be used to evaluate the rollover instability of a girder. Therefore, analytical and simplified numerical studies were performed to evaluate the critical wind load, lateral displacement and rotational angle that would induce rollover instability of a girder supported on an elastomeric bearing pad. The influence of the length and section properties of the girder on rollover instability was also investigated. The analytical method proposed in this study can be effectively used for evaluating the lateral behaviour and rollover instability of bridge girders and can also provide management values for securing the lateral stability of girders. The paper also provides a worked problem for a long-span typical European girder to determine critical values with application of the proposed method.

Glucocorticoid treatment is the first choice therapy for adults with minimal change nephrotic syndrome; however, this therapy associates with many adverse effects. Tacrolimus may be an alternative to conventional glucocorticoid therapy. To investigate this possibility, we conducted a prospective, randomized, controlled trial (WHO International Clinical Trials Registry Platform: ChiCTR-TRC-11001454) in eight renal units across China. We randomized enrolled patients with adult–onset minimal change nephrotic syndrome (n=119) to receive glucocorticoid therapy or tacrolimus after intravenous methylprednisolone (0.8 mg/kg per day) for 10 days. Patients received a conventional glucocorticoid regimen or tacrolimus monotherapy, starting with 0.05 mg/kg per day (target trough whole–blood level of 4–8 ng/ml) for 16–20 weeks and subsequently tapering over approximately 18 weeks. Remission occurred in 51 of 53 (96.2%; all complete remission) glucocorticoid-treated patients and 55 of 56 (98.3%; 52 complete and three partial remission) tacrolimus-treated patients (P=0.61 for remission; P=0.68 for complete remission). The groups had similar mean time to remission (P=0.55). Relapse occurred in 49.0% and 45.5% of the glucocorticoid- and tacrolimus-treated patients, respectively (P=0.71), with similar time to relapse (P=0.86). Seven (13.7%) glucocorticoid-treated and four (7.3%) tacrolimus-treated patients suffered frequent relapse (P=0.28); five glucocorticoid-treated and two tacrolimus-treated patients became drug dependent (P=0.26). Adverse events occurred more frequently in the glucocorticoid group (128 versus 81 in the tacrolimus group). Seven adverse events in the glucocorticoid group and two adverse events in the tacrolimus group were serious. Consequently, tacrolimus monotherapy after short–term intravenous methylprednisolone is noninferior to conventional glucocorticoid treatment for adult–onset minimal change nephrotic syndrome in this cohort.
Equilibrium Yield Curves and the Interest Rate Lower Bound
Authors: Nakata Taisuke , Tanaka Hiroatsu
Published: November 2016

We study the term structure of default-free interest rates in a sticky-price model with an occasionally binding effective lower bound (ELB) constraint on interest rates and recursive preferences. The ELB constraint induces state-dependency in the dynamics of term premiums by affecting macroeconomic uncertainty and interest-rate sensitivity to economic activities. In a model calibrated to match key features of the aggregate economy and term structure dynamics in the U.S. above and at the ELB, we find that the ELB constraint typically lowers the absolute size of term premiums at the ELB and increases their volatility around the time of liftoff. The central bank's announcement to keep the policy rate at the ELB for longer than previously expected lowers the expected short rate path, but its effect on term premiums depends on the risk exposure of bonds to the macroeconomy; while the announcement increases term premiums if bonds are a hedge against economic downturns, it decreases them otherwise.
Earnings Management and Corporate Investment Decisions
Authors: Yook Youngsuk , Julio Brandon
Published: November 2016

We investigate the relationship between earnings management and the efficiency of corporate investment decisions. Using discretionary accruals to measure intertemporal transfers of earnings, we show that earnings management exhibits a concave relationship with the investment sensitivity to investment opportunities as measured by Tobin's Q. We find that the association is concentrated among high Q firms. The effect is present among well governed firms, suggesting that better governed firms manage accruals strategically. The concave relationship suggests that the marginal impact of earnings management on investment efficiency decreases with the amount of earnings management. Using cases of misreporting, we document that excessive earnings management does not improve investment efficiency. Taken together, these results support the view that a moderate amount of earnings management helps improve corporate investment decisions while an excessive amount undoes the benefit of earnings management.
Intertextualidade e discurso no teatro de Dea Loher
Authors: Miguel Júlia Mara Moscardini
Published: November 2016

O discurso é composto por várias vozes, premissa anunciada desde os estudos de Bakhtin. Os avanços no campo da intertextualidade permitiram uma especificação maior do termo, abrindo espaço para discussão das várias ocorrências do intertexto na literatura. Na obra da dramaturga contemporânea alemã, Dea Loher, há a recorrência do trabalho com o intertexto, sendo que o presente artigo almeja investigar essas manifestações em duas de suas peças, Olgas Raum e Licht. Loher faz uso de citações, referências e alusões, recortando trechos de outros textos e acoplando-os à sua escrita. Esse jogo de recortar e colar é visível também na estética da dramaturga, que recorre a elementos presentes em outras estéticas teatrais e os adapta em sua obra, dando origem a um estilo original. Representante da vertente política no teatro, Loher proporciona ao leitor a possiblidade de reflexão e, nas duas peças em questão, ela o faz através da desconstrução do discurso canônico, mostrando como os discursos são fabricados e como estão ligados à manutenção do poder. Dessa maneira, o intertexto, a estética híbrida e outros recursos estéticos e linguísticos são orquestrados para abrigar essa temática política que chega até o leitor como questionamentos e indagações.
Murilo Mendes incorpora a poesia
Authors: Infante Ulisses
Published: November 2016

Murilo Mendes informa em textos autobiográficos que foi um cuidadoso leitor de poemas. Daí resultou o povoamento da memória por um numeroso acervo de imagens e referências, muitas das quais foram distribuídas em vários dos seus poemas. Rastrear a presença dessa matéria alheia na poesia de Murilo é um modo de captar interpretações e possibilidades de expressão percebidas no que assimilou. Também se podem captar os processos de composição poética baseados na ressignificação de imagens e unidades rítmicas incorporadas. O corpus de poemas e textos aqui abordado pretende mostrar como a incorporação – etimologicamente “junção”, “enfeixamento” – do alheio permitiu a Murilo Mendes, entre outras possibilidades, ponderar a figura do poeta na modernidade
The Honey-lips e The Guarany: os romances de José de Alencar em língua inglesa no final do século XIX
Authors: Bezerra Valéria Cristina
Published: November 2016

Nas últimas décadas do século XIX, dois romances de José de Alencar tiveram tradução e circulação em países de língua inglesa. Iraçéma: the honey-lips, em versão de Isabel Burton, foi publicada em 1886 em Londres e contou com recepção crítica em jornais do Reino Unido. The Guarany, traduzido por James William Hawes, saiu em forma seriada no ano de 1893 no jornal Overland Monthly and Out West Magazine, de São Francisco, nos Estados Unidos, país em que Alencar também foi referido pela imprensa local. Este trabalho se propõe a analisar as formas de recepção dessas obras e do nome de José de Alencar no Reino Unido e nos Estados Unidos. Objetiva ainda verificar o papel dos tradutores, editores, críticos e da imprensa na configuração da maneira como esse escritor foi avaliado e dado a ler, buscando considerar, sempre que possível, a relação desses intermediadores com a cultura brasileira. A recepção crítica de Alencar nesses países revela a boa avaliação desse escritor e a tradução de seus romances parece ter respondido a um interesse do público estrangeiro de se ilustrar.

Palavras-chave: José de Alencar. Tradução. Recepção.
Alice in Wonderland: uma tradução literária em imagens por Suzy Lee
Authors: Girão Luis Carlos , Cardoso Elizabeth Da Penha
Published: November 2016

Em 2015, o maior clássico da literatura infanto-juvenil moderna, Alice in Wonderland, celebra seus 150 anos de lançamento. A obra-prima do controverso Lewis Carroll já foi traduzida/retraduzida/adaptada nos mais diversos meios de expressão artística. Em 2002, despontando como um dos nomes revolucionários na contemporânea literatura para crianças e jovens, Suzy Lee publicou sua tradução intersemiótica em livro-imagem (publicação que se utiliza de narrativas pictóricas) para o livro ilustrado original do autor britânico. Em harmonia à ideia de Carroll referente a “um sonho dentro de um sonho”, Lee segue em sua publicação a ideia de “um livro dentro de um livro”, tornando ainda mais clara sua fonte de inspiração para a sua criação/recriação/adaptação. Objetivando realizar uma breve análise comparatista entre as obras literárias de Carroll e Lee, propomos um diálogo entre os pensamentos do linguista Roman Jakobson e os escritos do artista Julio Plaza no que se refere à tradução intersígnica, entre signos do código verbal para o código visual, para as versões de Alice in Wonderland aqui enunciadas. Sugerimos ainda uma aproximação com as ideias de Robert Stam sobre a adaptação literária, no caso da presente proposta, do livro ilustrado para o livro-imagem – narrativa composta por palavras para uma narrativa construída por imagens.
Predicting Abandonment of School-wide Positive Behavioral Interventions and Supports
Authors: Nese Rhonda , McIntosh Kent , Nese Joseph , Hoselton Robert , Bloom Jerry , Johnson Nanci , Richter Mary , Phillips Danielle , Ghemraoui Adam
Published: November 2016

This study examines predictors of abandonment of evidence-based practices through descriptive analyses of extant state-level training data, fidelity of implementation data, and nationally reported school demographic data across 915 schools in three states implementing school-wide positive behavioral interventions and supports (SWPBIS). Schools included in this study were tracked for a 5-year period after initial training, yet some elected to abandon SWPBIS at various times during implementation. Results showed that a small proportion of schools in the sample abandoned SWPBIS (7%). Logistic regression analysis identified school locale as the only statistically significant predictor of SWPBIS abandonment with schools located in cities being more likely to abandon. Results are discussed in terms of addressing types of schools at greater risk for abandonment and the importance of state-level training and coaching support.
Student Risk Screening Scale for Internalizing and Externalizing Behaviors: Preliminary Cut Scores to Support Data-Informed Decision Making in Middle and High Schools
Authors: Lane Lynne Kathleen , Oakes Wendy Peia , Cantwell Emily Dawn , Schatschneider Christopher , Menzies Holly , Crittenden Meredith , Messenger Mallory
Published: November 2016

We report findings of a convergent validity study examining the internalizing subscale (SRSS-16) of the Student Risk Screening Scale for Internalizing and Externalizing (SRSS-IE) with the internalizing subscale of the Teacher Report Form (TRF; Achenbach, 1991). Participants included 227 sixth- through 12th-grade students from nine schools across two states. Results of logistic regression and receiver operating characteristic curves suggest the following cut scores for the SRSS-16 for middle and high school students: 0–3 (low risk), 4–5 (moderate risk), and 6–18 (high risk) for internalizing behavior patterns, relative to the internalizing subscale of the TRF subscale. We conclude with a discussion of the findings and illustrations of how to use screening scale scores for decision making in a tiered system of supports, offering limitations and future directions for consideration.
A Língua Latina e a precisão conceitual
Authors: Oliveira Thiago Soares de
Published: November 2016

Este trabalho revisional, ligado ao campo terminológico, objetiva recuperar uma discussão fundamental em relação ao uso de termos latinos como forma de manutenção de precisão conceitual em determinados campos do saber como o Direito, por exemplo. Partindo da pesquisa bibliográfica como metodologia capaz de dar conta do escopo traçado, constroi-se o embasamento teórico para a análise de vocábulos e expressões latinos utilizados nas diversas searas do conhecimento especializado, bem como alguns já internalizados ao uso não técnico. Trata-se, pois, de um material analítico introdutório ao estudo dos vocábulos latinos.
Cultura política e processo eleitoral no Brasil
Authors: Piretti Brandão Ramon Taniguchi
Published: November 2016

O presente artigo se consagra a problematizar a cultura política do Brasil. Veremos quais foram as implicações – político-sociais – de uma cultura colonizada e baseada na exploração, escravidão e autoritarismo político. Trataremos historicamente a questão, percorrendo um período que vai do final do século XIX até o final da década de 1990. Evidentemente, devido ao extenso período histórico, nossa proposta gira em torno mais de uma problematização macro-cultural da dinâmica política e suas consequências nos processos eleitorais do que uma problematização específica que pretenda esgotar alguma questão.

Impacto de los ingresos por tasas retributivas en el departamento del Caquetá, Colombia
Authors: Beltrán Chica John Jairo
Published: November 2016

La política fiscal y la tributación ambiental se conciben teniendo en cuenta que el medioambiente es un sistema complejo de mecanismos físicos, biológicos y sociales que de alguna forma son determinantes en las disposiciones legales, políticas, económicas, técnicas y culturales de la sociedad. Al estudiar la experiencia que existe en el campo de la fiscalidad ambiental y la forma como se hace el cobro, son evidentes las ventajas que ofrece el marco institucional en países desarrollados por sus condiciones económicas y sociales, las que permiten el funcionamiento armónico de la sociedad. Para evaluar el sistema de cobro que realiza Corpoamazonia (Corporación para el desarrollo sostenible del sur de la Amazonia), es necesario tener en cuenta el área de jurisdicción que abarca la región sur de la Amazonia colombiana, la cual está comprendida por los departamentos de Amazonas, Caquetá y Putumayo, involucrando 31 municipios y nueve corregimientos departamentales, distribuidos territorialmente y por cuencas hidrográficas, especialmente de los ríos Amazonas, Caquetá y Putumayo.
La Alianza del Pacifico: nueva muestra del regionalismo en América Latina
Authors: Rojas Daniel , Terán José Miguel
Published: November 2016

La Alianza del Pacífico se instituyó como una propuesta de integración profunda entre Chile, Colombia, México y Perú. La pregunta que se plantea en este trabajo es ¿cuál de los enfoques del regionalismo en América Latina es el más idóneo para caracterizar teóricamente la iniciativa de la Alianza del Pacífico? En este sentido, se exponen los conceptos de regionalismo abierto y regionalismo estratégico para caracterizar esta iniciativa, y se resaltan sus límites a partir de evidencia empírica. El trabajo concluye que los conceptos de regionalismo que dan mayor énfasis a las dinámicas comerciales no son suficientes para comprender el funcionamiento y desempeño actual de la Alianza del Pacífico, por lo que se introduce un enfoque analítico complementario, el cual responde a dinámicas globales de largo plazo.
