Growth Characteristics, Physiological and Metabolic Responses of Teak (Tectona Grandis Linn. f.) Clones Differing in Rejuvenation Capacity Subjected to Drought Stress
Authors: Husen Azamal
Published: October 2017

Four-year old clones (FG1 and FG11) of teak (Tectona grandis Linn. f.), differing in rejuvenation capacity were grown in glazed earthenware pots. Drought treatments were imposed by withholding water for 20 days and rewatered to the field capacity daily for 5 days and the possible role of biochemical alteration and antioxidant metabolism in conferring photosynthetic capacity was determine by measuring photosynthetic traits, cellular damage and assaying activities of the superoxide dismutase (SOD) and peroxidase (PER) enzymes. Growth, relative water content (RWC), net photosynthetic rate (Pn), stomatal conductance (gs), chlorophyll fluorescence (Fv/Fm) and chlorophyll a, b, total chlorophyll and soluble protein content decreased significantly with increasing drought treatments from 5 to 20 days. Droughtinduced stress significantly increased the carotenoids content, relative electrolyte leakage and malondialdehyde (MDA) content, and, at the same time, accumulated free proline, free amino acid and soluble sugars in both clones. After re-watered to the field capacity daily for 5 days, both clones were shown significant recovery in the studied parameters. As compared with the FG11, the FG1 clone was more tolerant to drought as indicated by higher level of antioxidant enzyme activities as well as lower MDA content and electrolyte leakage. Similarly, drought stress caused less pronounced inhibition of Pn in FG1 than in FG11 clone. After re-hydration, the recovery was relatively quicker in FG1 than in FG11 clone. FG1 clone showed significant recovery in maximum quantum yield or photochemical efficiency of PSII (Fv/Fm) after 5 days of re-watering. The FG11 compared to the FG1, the former clone was less tolerant to drought than the latter. These results demonstrated that the different physiological strategies including antioxidative enzymes employed by the FG1 and FG11 clones of T. grandis to protect photosynthetic apparatus and alleviate drought stress. Furthermore, this study also provides ideas for teak improvement programmes and may be useful in breeding or genetic engineering for their tolerance to drought stress.
Differences Between Georgian and French Wild Cherry Populations and Consequence for Wild Cherry Breeding Programmes
Authors: Santi F. , Dufour J.
Published: October 2017

For the first time, the diversity of wild cherry in Caucasia was sampled: 5 populations of Georgia, together with 11 French populations. 23 alleles from 7 isozyme loci were scored, among them 6 new alleles in Georgia. Though the total number of alleles was higher in Georgia (A = 2.4) than in France (A = 2.0), the diversity was higher in France (He= 0.324) than in Georgia (He= 0.284). A higher level of differentiation was found in France (Fst= 0.094) than in Georgia (Fst= 0.057), and the total Fstwas even higher (0.108). Mean pairwise distances inside the French group, the Georgian group and between the two groups were 0.054, 0.037 and 0.094, respectively. The Pearson’s correlation coefficient between genetic and geographical distances was 0.58 (p = 0.014) between France and Georgia, which indicated a moderate pattern of isolation by distance. The number of migrants after correction of size was high among the French populations (Nm= 7.6) and even higher among the four nearby Georgian populations (Nm= 32), but it was very low between the pooled French populations and the pooled Georgian populations (Nm= 0.33). Georgia in Caucasia, as an extreme country in the distribution area, can be considered as a source of neutral gene diversity for wild cherry, and thus may also be one for adaptative gene diversity we could use to increase the genetic base of our western country wild cherry breeding populations.

Authors: Rweyongeza Deogratias M. , Yeh Francis C. , Dhir N. K.
Published: October 2017

We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11- year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30 replications, 58 open-pollinated families and single-tree plots. Individual tree heritability (hi
2) was 0.78 and 0.54 for 18 (H18) and 36 (H36)-week total height, respectively. The corresponding heritabilities for family means (hf
2) were 0.91 and 0.82. For root collar diameter, hi 2 were respectively, 0.61 and 0.22 at 24 and 54 weeks from germination. The corresponding hf
2 were 0.87 and 0.55. Heritability for bud flushing ranged from 0.13 to 0.46 (hi
2) and 0.44 to 0.83 (hf 2). The genetic correlation (ra) between H18 and H36 was 0.70 and that of D24 and D54 was 0.89, indicating a substantial change in family ranking in one growing season. The type B genetic correlation for H18 with field heights ranged from 0.22 to 0.30. Type B genetic correlations of field height with all other seedling traits were very low and largely negative. It can be concluded that: (1) age-age correlation of seedling height can be expected to decline drastically even in a stable environment of the greenhouse, (2) heritability for growth potential is meaningful when estimated on cumulative growth not on individual annual growth increments that are susceptible to short-term environmental variation, (3) dates of bud flushing did not influence variation in height and root collar diameter, and (4) field growth potential is better predicted by greenhouse growth potential than other morphological and shoot phenological traits.
Clonal Variation in Acorn Production and its Effect on the Effective Population Size in a Quercus acutissima Seed Orchard
Authors: Kang K. S. , Kim C. S. , El-Kassaby Y. A.
Published: October 2017

Acorn production was surveyed for eight consecutive years (2000-2007) in a 94-clone Sawtooth oak (Quercus acutissima) seed orchard established in 1992. Acorn production commenced in 2000 and peaked in 2005 and was characterized by a 3-4 years interval. Sixty out of the orchard’s 94 clones were consistent producers across the study period. Acorn production’s Pearson productmoment and Spearman rank correlation coefficients were significant and consistently positive over the eight years study period. Parental cumulative reproductive output, represented by parental balance curves, slightly varied among mast years and showed steady improvement (less distortion) over years. Effective population size (Np) was high in moderate and good acorn production years; however, departure from clonal equal contribution was observed throughout the study period. Parental effective population size was estimated under various scenarios of male fecundity (pollen production is: 1) proportional to clone size, 2) equal to female contribution, and 3) equal across all clones) resulted in high Np and low group co-ancestry under equal male fecundity scenario while moderate Np size and group co-ancestry were observed when male fecundity was assumed to be proportional to clone size (i.e., ramet number).
Karyotype Analysis of Alnus Mill. (Betulaceae) Species Originating From Northeastern Asia

Published: October 2017

Alnus Mill. (alder) is an ecologically valuable tree genus. It is essential to study its genetic makeup in order to use alder trees to their full potential. Five specimens from four Alnus species (A. mandshurica, A. pendula, A. sibirica, and A. sieboldiana), found in northeastern Asia, were subjected to karyotype analysis. The analysis showed that these tree samples could be divided into three categories based on chromosome numbers or ploidy levels: viz., 2n = (4x) = 28, 2n = (8x) = 56 and 2n = (16x) = 112. The differences in chromosome number and karyotype parameters among Alnus species and even within the same species possibly resulted from natural polyploidization. Comparing the chromosome numbers of Alnus species in China with those in Japan showed that there appear to be only two categories in China, whereas there are up to five categories in Japan. The earliest fossil records of Alnus pollen were also discovered in Japan. We conclude that the center origin of Alnus spp. is Japan rather than China.

Published: October 2017

Realized genetic gain trials for coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) at five different sites with four different spacings were assessed at age 12 to compare early gain predictions in growth from small plot progeny test designs to those obtained from large block designs. Seedlings from three genetic levels, i.e., local wild-stand controls (WS), a mid-gain seedlot (MG), and a top-cross seedlot (TC) were planted in 12 × 12 tree plots with two replications at spacings of 1.6 m, 2.3 m, 2.9 m and 4.0 m. Two replications of a “single-tree plot” design at 2.9 m spacing for the three genetic levels (30 trees per genetic level) were also established, to allow for more detailed comparisons between single-tree and multiple-tree plot means. Although these trials are still relatively young, trees in the closest spacing had the highest levels of mortality with the TC trees having the highest rate of survival. Height gains in the block trials ranged from 10.4% to 16.1% for MG and TC trees, respectively, and were relatively close to the predicted values; however, volume (individual tree and volume/ha) gains exceeded expectations. Effects of genetic entry on height at age 12 were highly significant, while spacing, genetic entry by spacing, and genetic entry by test site interactions were not significant. We also compared height growth over the first 12 years to growth estimated from the “Bruce height growth model” for Douglas-fir and found that on four of the five test sites our MG and TC seedlings follow the expected height growth trajectories.

Published: October 2017

The development of molecular markers unambiguously distinguishing groups at different taxonomic levels has numerous forensic applications. The identification of tropical timber is of particular interest in this context. We describe the development of SCAR (Sequence Characterized Amplified Region) markers for forensic applications taking the example of two closely related species of the tropical tree family Shorea (Dipterocarpaceae). Two AFLP (Amplified Fragment Length Polymorphism) fragments have been described earlier showing strong differentiation between S. leprosula and S. parvifolia. The AFLP markers were isolated from a gel, re-amplified, cloned and sequenced. Primer sets were designed from these sequences and AFLP fragments were converted into SCAR markers. The SCAR markers and PCR-RFLP markers of the chloroplast region trnLF digested with HinfI were used to screen in total 557 samples of S. parvifolia and S. leprosula from nineteen widely separated populations in Indonesia. Complete genetic differentiation between species was observed based on the putatively nuclear SCAR marker and the PCR-RFLP of the cpDNA region. We found a good agreement between leaf morphological variation and species identification based on both marker types and no indication for interspecific hybridization.

Myeloma multiplex is a malignant disease of bone marrow plasma cells. It is usually confined to the bone marrow, but in rare cases, patients can develop extramedullary disease. The involvement of lymph nodes is rare and can be a diagnostic challenge. Here, we describe a 36-year-old male patient who presented with abdominal pain and discomfort initially. An abdominal ultrasound followed by computed tomography (CT) revealed retroperitoneal and mesenteric lymph node enlargement. Biopsies of the abdominal lymph node and infiltrated colon showed a plasma cell infiltrate positive for CD79α, CD38, CD138, kappa light chain and VEGF2. Multiple myeloma with extramedullary localization was diagnosed. After six cycles of chemotherapy consisting of doxorubicin, dexamethasone and thalidomide followed by autologous haematopoietic cell transplantation, the patient achieved complete remission. Specifically, a CT scan after therapy showed enlarged lymph nodes in the abdomen, but PET CT scans did not detect any metabolically active foci. Thee years after the completion of therapy, the patient remains in remission. This case illustrates a rare presentation of extramedullary myeloma involving the abdominal lymph nodes, which could have been potentially mistaken for a lymphoid malignancy.

Published: October 2017

Discovery of the metallopharmaceutical cisplatin and its use in antitumour therapy has initiated the rational design and screening of metal-based anticancer agents as potential chemotherapeutics. In addition to the achievements of cisplatin and its therapeutic analogues, there are significant drawbacks to its use: resistance and toxicity. Over the past four decades, numerous transition metal complexes have been synthesized and investigated in vitro and in vivo. The most studied metals among these complexes are platinum and ruthenium. The key features of these investigations is to find novel metal complexes that could potentially exert less toxicity and equal or higher antitumour potency and to overcome other pharmacological deficiencies. Ru complexes have a different mode of action than cisplatin does, some of which are under clinical trials for treating metastatic or cisplatin-resistant tumours. This review consists of the current knowledge, published and unpublished, related to the toxicity of metallopharmaceuticals, and special attention is given to platinum [Pt(II) and Pt(IV)] and ruthenium [Ru(II) and Ru(III)] complexes.

Published: October 2017

Spontaneous subcapsular renal hematoma (SSRH) emerged as a complication of acute pyelonephritis (APN) is an extremely rare condition. We showed a patient aged 63 years hospitalized due to languor, febrility, abdominal pain accompanied by nausea and vomiting. Ultrasound (US) examination of the abdomen and multidetector computed tomography (MDCT) showed the presence of subcapsular hematoma of the left kidney with calculus in the initial part of the left ureter. Laboratory tests registered a positive inflammation syndrome, anemia and an increase in nitrogen compounds. Based on laboratory results, clinical presentation and imaging techniques it has been found that it is APN with spontaneous subcapsular hematoma. After application of non-surgical treatment which included antibiotic therapy with percutaneous drainage of hematoma, a good clinical response with regression of subjective symptoms and hematoma was obtained. On repeated US and MDCT after 18 months no pathological changes in the kidneys were registered. Spontaneous subcapsular hematoma extremely rare occurs as a result of APN associated with calculosis. The use of non-surgical treatment, which includes appropriate antibiotic therapy with percutaneous drainage of hematoma would represent a method of first choice.
Channel surfing uncovers a dual‐use transporter
Authors: Minor Daniel L
Published: October 2017

Beyond their roles in generating nerve impulses, ion channels are important for many facets of cell biology, including swelling and osmotic stress responses. Sabirov and colleagues now report that the prostaglandin transporter SLCO2A1 is a central component of the ubiquitous Maxi‐Cl anion channel. These findings add to a growing number of transporters displaying ion channel activity and not only provide a molecular handle for future Maxi‐Cl physiological and biophysical studies, but also underscore general questions about the principles that underlie such transporter/channel dual‐use behavior.

Razvoj talijanske estetike nakon Crocea
Authors: Roščić Vani
Published: October 2017

Filozofska promišljanja neoidealističkog usmjerenja Benedetta Crocea i Giovanni Gentila imala su u prvoj polovici dvadesetog stoljeća vrlo snažan utjecaj ne samo na talijansku kulturu nego i na promišljanje estetičkih pitanja u Hrvatskoj. Nakon Drugog svjetskog rata u Italiji više ne postoji snažan utjecaj samo jednog filozofskog pravca, nego se talijanska estetika otvara prema pragmatizmu, fenomenologiji, egzistencijalizmu, personalizmu i hermeneutici, no rasprave hrvatske estetike s ostalim talijanskim autorima nisu nastavljene s jednakim intenzitetom. U obradi filozofske misli izabranih autora usmjerit ćemo se prema onim estetičkim pitanjima koja izviru iz različitih polemika suvremenih talijanskih estetičara s Croceovom estetikom, a pokušavaju dati adekvatan odgovor estetike na odnos suvremenog društva prema lijepom i umjetnosti.
Učenje kroz prizmu socijalnog konstruktivizma

Published: October 2017

U današnjim shvaćanjima čovjekovog razvoja i učenja sve više se ističe značaj kontekstualnih, posebice socijalnih utjecaja, kao i njihovog dinamičnog međudjelovanja na pojedinca i, obrnuto, pojedinca na njih. Dinamična su-konstrukcija navedenih odnosa izgrađuje pojedinca, pri čemu je on aktivan akter dinamike promjena do kojih dolazi kod njega, ali i u njegovoj okolini. Znanja, sposobnosti, kompetencije konstruiraju se temeljem čovjekovog postojećeg iskustva te konteksta u kojem se učenje događa. Temeljne promjene u učenju i poučavanju su prijelaz na otvoreni sustav znanja i usmjerenje na sâme procese učenja. Učenje i poučavanje se otvaraju te se promatraju u daleko širem materijalnom, socijalnom, kulturnom kontekstu od onog uskog nastavnog. Sveto zahtijeva redefiniranje kurikuluma, kreiranje poticajnog okruženja učenja i poučavanja, ali i promijenjeni opći pristup u obrazovanju nastavnika.U radu se kratko iznose aktualne konstruktivističke interpretacije učenja i konteksta u kojem se ono odvija. Poseban naglasak stavlja se na socijalni konstruktivizam, zajednice prakse/učenja i informalne oblike učenja. Daje se pregled izmijenjene perspektive o učenju kroz niz od sedam principa te, u konačnici, refleksije teorije socijalnog konstruktivizma na praksu školskog učenja i poučavanja.

Rad promišlja i prikazuje interakciju globalizacije i kulture kao sustava značenja koji reguliraju društveni život, odnosno na općoj razini skicira i analizira neke teze glede odnosa kulture i globalizacije. Globalizacija je društvena, ekonomska, politička i kulturna činjenica suvremenog društva, totalni fenomen. Ona je sveprisutna pojava današnje epohe i ostavlja upečatljive tragove svoje nazočnosti u svim prostorima u kojima se odvija. Osnovni aspekti globalizacije su ekonomski i politički odnosi koji se razvijaju između zemalja i regija i sve više čine okvir nekoj vrsti kulturnoga međusobnog približavanja u kojemu izvjestan broj istih vrijednosti prolazi krozviše zemalja s tendencijom prema kulturnoj jednakosti.Globalizacijski proces uključuje sve veći broj kulturnih elemenata, proširuje prostorne, kvantitativne i kvalitativne dimenzije kulture, a uključivanjem sve većega broja ljudi potiče aktivno djelovanje kulture. U prošlosti i danas dodiri kultura su se skladno prožimali, ali i iskazivali dramatične i često konfliktne oblike. Istinsko življenje trebalo bi biti međusobno razumijevanje i poštovanje, sporazumijevanje i ravnopravna suradnja jer smisao čovjeka ogleda se u humanosti.

Practical approach to predict the shear strength of fibre-reinforced clay
Authors: Mirzababaei M. , Mohamed M. , Arulrajah A. , Horpibulsuk S. , Anggraini V.
Published: October 2017

Carpet waste fibres have a higher volume to weight ratio and once discarded into landfills, these fibres occupy a larger volume than other materials of similar weight. This research evaluates the efficiency of two types of carpet waste fibre as sustainable soil reinforcing materials to improve the shear strength of clay. A series of consolidated undrained (CU) triaxial compression tests were carried out to study the shear strength of reinforced clays with 1% to 5% carpet waste fibres. The results indicated that carpet waste fibres significantly improve the effective shear stress ratio and deviator stress of the host soil. Addition of 1%, 3% and 5% carpet fibres could improve the effective shear stress ratio of the unreinforced soil by 17.6%, 53.5% and 70.6%, respectively at an initial effective consolidation stress of 200 kPa. In this study, a nonlinear regression model was developed based on a modified form of the hyperbolic model to predict the relationship between effective shear stress ratio, deviator stress and axial strain of fibre-reinforced soil samples with various fibre contents when subjected to various initial effective consolidation stresses. The proposed model was validated using the published experimental data, with predictions using this model found to be in excellent agreement.
Built environment education for children – museums in focus
Authors: Brković Dodig Marta
Published: October 2017

Museums dedicated to architecture and the built environment, city and local history museums and children's museums are emerging as key sites offering built environment education (BEE) for children. While the practice of BEE in museums is very rich, the research on this topic is difficult to discern. The literature discussing the settings for BEE encompasses a broad range of building and institution types, without specifically focusing on the BEE work of museums. This exploratory pilot study analyses four case studies of museums as contexts for BEE for children, to evaluate the successes and limitations of BEE programmes in museums, complement the existing knowledge and map fruitful avenues for future research. On the basis of interviews with museum staff, this research suggests that BEE activities in museums widen the access for children to BEE, spur children's interest and enthusiasm for BE topics, help children develop relevant BE vocabulary and constitute potent BEE experiences for children. Yet, much further pre- and post-exhibition evaluations on what BEE lessons children exactly learned and what relevant BE skills they developed are needed.

The community colleges came into existence in Denmark in the middle of the 19th century originally with the aim of providing available alternative for the rural adult population excluded from education to be able to catch up with the social and economic challenges of the era. The method and the instituion proved to be a success story both in Denmark and in the following decades first of all in Scandinavia, which has still been going on unbeaten.Attempts to establish educational institutions of similar type were made in Hungary as well between the two world wars but their success was altering significantly. In our lecture we would like to make attempts to reveal some determining factors which made the success of Hungarian community colleges altering in the era, but at the same time to compare all this with the present practice of community colleges examining the question whether the principles, practice and experience of the period between the two world wars may be used in the changed social, ecoonomic, educational/teaching/learning environment during the establishment of an optimal organisational, operational system.According to our observations this approach makes our research up-to-date. Our key issues in the focal point are (comparing the 20ies – 30ies to the practice of today): to what extent the circle of founders, actuators, the composition of the target group, the maintainers, financing, the functions of the organizations, the educational aims, contents, methods, the forms of education changed in the different types of community colleges. We have examined the geographical location, distribution of the institutions, the characteristic features of the settlements and their configuration, accessibility, which may be a sore point in view of the fact that – contrary to the classical Scandinavian community colleges - boarding schools are quite rare types in Hungarian practice. We have used archival sources, analysed specialized literature, done research work, used statistical data and own research results as well.
The possible benefits of using comic books in foreign language education: A classroom study
Authors: Karap Zsuzsanna
Published: October 2017

Comic books are experiencing a steady rise in popularity. Not only are they being investigated as subjects of literary studies and other fields of research (e.g., McCloud, 1993; Wolk, 2007; Darius, 2012), they are also getting recognised as instructional resources to improve literacy skills and maintain motivation (O’English, Matthews, Lindsay, 2006). They also have several advantageous features that support foreign language learning. The present study aimed at investigating some of these (guessing meaning of new words; lowered anxiety; better recall) by the use of comic books in the classroom. Three groups of students were recruited (n=14; 14; 8) in a secondary grammar school, as part of the author’s 11-week-long formal English teaching practice.

Published: October 2017

Life long learning is a general paradigm in the 21st century. One of the European Union’s goal is to teach effective individual learning. So giving students the opportunity to learn new learning methods and strategies is really important.I examined the learning habits of students of a primary school in a town (N=137). My first hypothesis is that there is a difference in the use of learning methods between the lower and the upper levels of primary school. However, I found significant differences in five methods, the upper level students evaluated the frequency of the use of these methods with a lower value on average. Based on this result I have concluded that the upper level students use the methods mentioned with little conscience (Ledniczki, 2016). I have also found that students who study for themselves have better grades (Table 2). This has proved my assumption – that there is a connection between effective learning and academic achievement – to be right.

Although there has been a change of paradigm in teaching literature at secondary schools, the traditional, Literary Criticism-based, chronological method is used nowadays. As a consequence, there might not be enough time for modern authors, especially writers and poets after 1945. There is usually no time for teaching the works of Miklós Mészöly, for instance, although they could be integrated into the curriculum based on numerous methods. A proposal is offered for this problem in this study.

Authors: Kalmár Erika Anna
Published: October 2017

Major changes occurred in the Hungarian educational system during the last years. A new career model for teachers has been introduced and in connection with that the promotion and payment system of the teachers have changed. The structure of the maintainers of schools has been reformed and in connection with that the finance for schools has also been reformed. These changes have significantly influenced the Hungarian teachers’ society. In my essay I introduce the reasons behind the changes of the “teacher politics”, the freshly introduced career model, the changes in the structure of the maintainers of the schools, and I touch upon the financial questions of schools. Then I introduce the financial model of a school of a small town.

This study reveals the extent to which PhD students of pedagogy in Hungary are aware of the applicability of Computer Assisted Qualitative Data Analysis, focusing on MAXQDA and it also points out the frequency of its use in their practice. Results were gained by means of structured interviews and their coding was based on deductive and inductive logics. 109 coded units and 34 different codes led to the exploration of the strong points and difficulties of MAXQDA and Computer Assisted Qualitative Data Analysis and the illustration of those pedagogical research areas in which students claimed their use to be relevant.
ANÁLISE DE COMPORTAMENTOS ASSOCIADOS A DISTÚRBIOS NUTRICIONAIS EM ADOLESCENTES NORDESTINOS
Authors: França Marcos Antônio Rodrigues , Aragão Herifrania Tourinho , Jeraldo Veronica de Lourdes Sierpe
Published: October 2017

O objetivo da pesquisa foi analisar comportamentos de adolescentes associando-os à ocorrência de distúrbios nutricionais. Foram entrevistados 694 adolescentes entre 15 e 18 anos, de sete municípios no sul de Sergipe e aplicados dois instrumentos (PAQ-C e HADS), além da avaliação antropométrica. A prevalência de baixo peso nos adolescentes foi de 4% entre os rapazes, que corresponde a 81,3% do total de adolescentes de ambos os gêneros com baixo peso e de 0,9% entre as moças, correspondendo a 18,7% de adolescentes de ambos os gêneros com esse perfil nutricional. Em relação ao sobrepeso, a prevalência entre os rapazes foi 9,0% e, entre as moças foi 11,1%. Foram classificados como ativos fisicamente 13% dos rapazes e 9,88% das moças. Entre as moças a prevalência de ansiedade e de sintomas depressivos foi de 20,68% e 15,1% respectivamente, enquanto que nos rapazes foi de 19,14% e 12,7%. A ansiedade mostrou correlação significativa com o sobrepeso entre os rapazes o mesmo não acontecendo com as moças. No entanto a correlação entre ansiedade e baixo peso se observa significativa somente entre as moças. O estado de depressão mostrou significativa correlação com o baixo peso e o sobrepeso entre os rapazes. Nas moças essa correlação foi significativa com o sobrepeso. Os resultados apontam esses comportamentos como variáveis de risco para o baixo peso e para o sobrepeso em ambos os gêneros e a presença deles podem ser atribuídos às pressões impostas pelas escolhas de planos futuros que o adolescente precisa assumir nessa fase da vida.
INTERAÇÃO MORCEGO-PLANTA: UMA ANÁLISE CIENCIOMÉTRICA DE ESTUDOS NO BRASIL
Authors: Rodrigues Jorge Thais Martinez , Silva Andrew Vinícius Cristaldo da , Ortêncio Filho Henrique
Published: October 2017

Objetivou-se realizar uma análise cienciométrica para verificar a quantidade de produções científicas publicadas em relação à interação morcego/planta no Brasil, compreendido entre os anos de 1994 a 2014. O levantamento dos artigos foi feito através de dois bancos de dados: Thomson Reuters e SCIELO Brasil. Utilizou-se as palavras “Brazil”, “Chiroptera”, “pollination”, “seeds dispersal” e depois, “Brazil”, “bats”, “interaction”, “seed”, “pollination”. Os trabalhos foram agrupados de acordo com o ano de publicação, região do Brasil, bem como artigos, descritivo, teórico ou experimental. De acordo com o levantamento, 65% dos artigos, são considerados descritivos, por possuírem caráter investigativo in situ. Conforme o ano de publicação, dos artigos levantados, houve um crescimento a partir do ano de 2006, uma vez que, de 2006 a 2014, foram obtidos quinze artigos. Em contrapartida, de 1994 a 2005, apenas cinco foram publicados. Os esforços de pesquisas foram encontrados na Região Sudeste. Com o levantamento realizado verificou-se deficiência em estudos sobre o tema. Sendo o Brasil o país com a maior diversidade de fauna e flora no mundo, e as relações entre morcego e planta essenciais para a dinâmica florestal, principalmente na regeneração de áreas desmatadas, é de fundamental importância a realização de novos trabalhos e a divulgação científica dos mesmos para que haja avanços na ciência e melhoria na qualidade ambiental.
GÊNERO: UMA CATEGORIA ÚTIL PARA A HISTÓRIA DA ESCRAVIDÃO NO BRASIL
Authors: Reis Adriana Dantas
Published: October 2017

O Brasil é marcado estruturalmente pela escravidão e pelo patriarcalismo. É muito difícil entender a complexidade da nossa formação sem um olhar de intersecção entre as relações escravistas, de gênero e de cor/raça. Apesar dessa constatação a História Social da escravidão no Brasil, abandonou ou minimizou o conceito de patriarcalismo nas abordagens de suas pesquisas, optando por outros conceitos teóricos, mais sensíveis às culturas e às construções simbólicas dos agentes históricos. Este artigo propõe a retomada do patriarcalismo de Gilberto Freyre e suas possíveis ressignificações a partir do conceito de gênero, trazendo-o para o centro da escravidão. Ou seja, propõe o gênero como estrutural nas relações escravistas e convida as historiadoras e os historiadores da escravidão para os debates, no sentido de que o patriarcalismo/ gênero seja definitivamente, considerado como indispensável para compreender o escravismo.
DA POSSIBILIDADE DE PENHORA DO CAPITAL DE GIRO
Authors: Oliveira Carlos Cristiano Meneguini de , Maldonado Bruno Teixeira
Published: October 2017

Este artigo científico visa estudar a possibilidade de penhora do capital de giro de uma empresa dentro do processo de execução, bem como quais são os procedimentos a serem observados neste caso. Para tanto, serão analisados quais bens compõem o capital de giro empresarial e qual sua importância para a saúde financeira da empresa. Para tanto, este trabalho se apóia em uma pesquisa qualitativa, ou seja, em conhecimentos específicos a respeito da matéria, fruto de pesquisa bibliográfica e de normas aplicáveis ao assunto. Como resultado, concluiu-se que os atos de penhora e expropriação devem evitar a constrição dos ativos circulantes da empresa executada, posto que o mesmo é fundamental para manutenção da atividade empresarial. Ademais, verificou-se que a procedimentalidade adotada pelos tribunais pátrios neste tipo de caso não é pacífica, de modo que se concluiu como mais acertada a constrição em último caso, e somente através dos trâmites legais determinados pelo artigo 655-A, § 3º, e 678 do CPC e arts. 866 e 863 do CPC/2015.
Documentando dilemas. Sobre la relevancia de los casos éticamente ambiguos
Authors: Van de Vall    Renée
Published: October 2017

Este artículo sostiene que la documentación proporciona un mejor servicio a la conservación de arte contemporáneo cuando no solo recopila y registra información sobre las obras, sino que también recoge los dilemas a los que los conservadores han tenido que enfrentarse al tomar decisiones sobre sus estrategias de conservación. La razón es que, en las últimas dos décadas, una práctica cada vez más reflexiva ha favorecido una situación en la que están emergiendo nuevos paradigmas éticos que sirven para diferentes tipos de trabajos artísticos y sus diferentes lógicas de perpetuación. El artículo propone tres paradigmas diferentes con sus correspondientes casos paradigmáticos, argumentando que solo un método de deliberación ética “caso-a-caso” (ética casuística) servirá para articular una serie de principios y directrices adecuados a los más recientes paradigmas. Para posibilitar esta deliberación, se hace necesario documentar los dilemas éticos en la conservación. Además, la mayoría de los casos resultarán bastante conflictivos, dado que muchas obras de arte consisten en la unión heterogénea de objetos, ideas y prácticas, con sus propias lógicas diferenciadas de perpetuación, mientras otras se mueven entre distintas lógicas, o pasan de una lógica a otra en el transcurso de sus biografías. Por tanto, la documentación de los dilemas continuará siendo necesaria para facilitar un acercamiento casuístico a la hora de tomar decisiones con responsabilidad y desarrollar un cuerpo de experiencia profesional.

Panel Data Models of New Firm Formation in New England
Authors: Parajuli Jitendra , Haynes Kingsley E.
Published: October 2017

This study examines the impact of the determinants of new firm formation in New England at the county level from 1999 to 2009. Based on the Spatial Durbin panel model that accounts for spillover effects, it is found that population density and human capital positively affect single-unit firm births within a county and its neighbors. Population growth rate also exerts a significant positive impact on new firm formation, but most of the effect is from spatial spillovers. On the contrary, the ratio of large to small firm in terms of employment size and unemployment rate negatively influence single-unit firm births both within counties and among neighbors. However, there is no significant impact of local financial capital and personal income growth on new firm formation.

This research was conducted for estimating the knowledge and prevention of nosocomial infection among ward nurses at Federal Medical Centre (FMC), Umuahia Abia state. Four objectives were set, and four questions were formulated. A descriptive survey research method was used for the study. A sample size of one hundred and fifty (150) nurses was drawn from eight wards (medical and surgical), at FMC, Umuahia. A self-developed questionnaire with seventeen (17) structured questions was the instrument of data collection. Data were collected, analyzed, and presented in tables, pie chart, bar chart, histogram, and percentages. The results revealed that the nurses were well knowledgeable about nosocomial infection, although little deficiencies existed in the area of infection control practice and compliance, such as hand washing frequency. This study therefore recommends continuing education/seminar/workshop for all health care givers, to sensitize them with the knowledge and practice of nosocomial infection.
The use of molecular genetic information in genetic improvement programmes for pigs
Authors:   Iowa State University, USA, Dekkers Jack C. M.
Published: October 2017

Genetic improvement of pigs has been achieved by selection of individuals for breeding based on estimated breeding values (EBV), derived using phenotypes for important traits. Ideally, phenotypes on the individual itself and its relatives are utilized in order to obtain the most accurate estimate of the breeding value of the individual. However, there are multiple challenges and limitations associated with these phenotype-based programs. Many of these can be overcome by using molecular information to help predict breeding values and inform selection decisions. This chapter describes how molecular genetic information can be used to enhance selection programs in pigs, what is required to develop such information, and what strategies are available for the use of molecular information in breeding programs. Example cases, challenges and future prospects are also reviewed.
Factors affecting the reproductive efficiency of pigs
Authors:   North Carolina State University, USA, Almond Glen W. , Mahan-Riggs Emily ,   North Carolina State University, USA
Published: October 2017

Solving problems associated with reproductive failure in sow herds can be a challenge. It is critical to meet breeding targets on a routine basis, and to achieve the appropriate farrowing rates and litter sizes. Reproductive failure interferes with the consistent production of pigs, which ultimately results in the suboptimal number of pigs for market. This chapter will highlight some of the factors affecting reproductive efficiency, including gilt development, litter size, control of the weaning to oestrus interval and seasonal infertility. Attention is given to various management strategies which help producers to continue to be profitable.

Published: October 2017

Linking advances in our understanding to sustainable production of pig meat requires a more lateral perspective centred on the primary drivers of sustainability. This chapter considers advances in nutritional requirements and metabolism and how these contribute to sustainable production of pig meat, including the need to maintain sow body condition throughout gestation and lactation and ways of reducing variation in pork production systems. The chapter examines strategic use of metabolic modifiers and the importance of matching nutrient requirements to pig diet specifications and optimising gut health and nutrient utilisation capacity. The chapter provides a useful overview of understanding the interaction between nutrition and pig health.
