AFRICAN STUDIES IN CHINA IN THE 21ST CENTURY: A HISTORIOGRAPHICAL SURVEY
Authors: Anshan Li
Published: November 2017

Com o rápido desenvolvimento das relações China-África, africanistas fora da China têm mostrado grande interesse no engajamento acadêmico China-África. Um dos aspectos importantes é o que tem sido feito na China em relação aos estudos africanos. Apesar do comércio da China com a África tenha aumentado de 10,5 bilhões de dólares em 2000 para 220 bilhões em 2014, os estudos africanos na China não tiveram tanta sorte quanto o comércio. Entretanto, o desenvolvimento dramático dessa relação tem dado novas oportunidades e desafios aos africanistas chineses. Este artigo vai elucidar o que os africanistas chineses têm estudado no período de 2000-2015. Por quais temas eles têm se interessado? Quais são as conquistas e fraquezas? O artigo foi dividido em quatro partes: foco e novos interesses, conquistas, novos acadêmicos, referências e considerações.

A Review and the Conservation Implications of Aquatic Behaviour and Drowning in Jumping Mice (Dipodidae: Zapodinae)
Authors: Frey Jennifer K.
Published: October 2017

Jumping mice (Dipodidae: Zapodinae) have a generalized terrestrial quadrupedal locomotion with specializations for saltatory and scansorial locomotion. I reviewed first-hand accounts of aquatic behaviour in the literature and confirmed that jumping mice are semi-aquatic, using both primitive quadrupedal paddling on the surface as well as the more derived simultaneous bipedal pelvic paddling while swimming underwater. Although proficient swimmers, jumping mice are also prone to drowning, especially in human-made pools. Management of populations of jumping mice with conservation concern should consider potential hazards faced by jumping mice in an aquatic environment.
Short-term Change in Forest Metrics at Grand Portage National Monument, Minnesota
Authors: Sanders Suzanne , Kirschbaum Jessica
Published: October 2017

Forest health monitoring programs can provide routine feedback of key indices and periodic updates of ecosystem health. A forest monitoring program was initiated at Grand Portage National Monument in 2007 with plots resampled in 2014. Grand Portage National Monument is within the southern boreal forest and the suitable habitat for most of its common overstorey species is expected to shift northward and out of the park as climate change progresses. We assessed short-term change in forest health on 20 plots by specifically evaluating change in overstorey density and basal area, forest community composition, and White-tailed deer (Odocoileus virginianus) browsing impacts on the herbaceous layer. Pooled across all overstorey species, both density and basal area increased between sampling events, but neither differed among habitats. For individual species of interest, responses were varied, although balsam Fir (Abies balsamea) increased in both density and basal area over the seven years. The frequency of quadrats supporting at least one preferred browse species did not differ between sampling years although this was greater in upland plots (81%) compared with wet mesic sites (66%). The effect of sampling year on species’ richness depended on habitat. In 2007, richness was higher in upland plots, although in 2014, richness was higher in wet mesic plots. Pooled across both sampling years, modified floristic quality index was greater in wet mesic plots. Our work demonstrates the increasing dominance of A. balsamea at Grand Portage National Monument and that notable differences in forest metrics can be observed over relatively short times.
Context-sensitive constraints for access control of business processes
Authors: Milosavljevic Gordana , Sladic Goran , Milosavljevic Branko , Zaric Miroslav , Gostojic Stevan , Slivka Jelena
Published: October 2017

Workflow management systems (WfMS) are used to automate and facilitate business processes of an enterprise. To simplify the administration, it is a common practice in many WfMS solutions to allocate a role to perform each activity of the process and then assign one or more users to each role. Typically, access control for WfMS is role-based with a support of constraints on users and roles. However, merely using role and constraints concepts can hardly satisfy modern access control requirements of a contemporary enterprise. Permissions should not solely depend on common static and dynamic principles, but they must be influenced by the context in which the access is requested. In this paper, we focus on the definition and enforcement of the context-sensitive constraints for workflow systems. We extended the common role-based constraints listed in literature with context-sensitive information and workflow specific components. Also, we propose a mechanism for enforcing such constraints within WfMS.
Managing software requirements changes through change specification and classification
Authors: Jayatilleke Shalinka , Lai Richard , Reed Karl
Published: October 2017

Software requirements changes are often inevitable due to the changing nature of running a business and operating the Information Technology (IT) system which supports the business. As such, managing software requirements changes is an important part of software development. Past research has shown that failing to manage software requirements changes effectively is a main contributor to project failure. One of the difficulties in managing requirements changes is the lack of effective methods for communicating changes from the business to the IT professionals. In this paper, we present an approach to managing requirements change by improving the change communication and elicitation through a method of change specification and a method of classification. Change specification provides a way such that communication ambiguities can be avoided between business and IT staff. The change classification mechanism identifies the type of the changes to be made and preliminary identification of the actions to be taken. We illustrate the usefulness of the methods by applying them to a case study of course management system.
Dynamics of the real exchange rate in European emerging economies: Evidence from quantile regression
Authors: Mladenovic Zorica , Bodor Sladjana
Published: November 2017

The sustainability of purchasing power parity (PPP) theory is examined within the quantile autoregression model for the monthly data of the euro and the US dollar-based real exchange rate (RER) in selected European economies (the Czech Republic, Hungary, Poland, Romania, Serbia and Turkey). Period from January 2000 to December 2014 is covered. The application of quantile autoregression model is motivated by the necessity of identifying asymmetric behavior of the RER due to the shocks of different size and sign. The empirical results support to some extent the PPP theory for the euro- and US dollar-based RER in Romania, Serbia, and Turkey. The euro-based RER in Hungary and Poland is also identified to confirm the PPP theory. The dynamics of the RER in the Czech Republic cannot be associated with the PPP validity. The persistence of the euro-based RER is estimated to be more prominent after the depreciation shocks of smaller size.
Employment protection and gender wage gap in Europe
Authors: Perugini Cristiano
Published: November 2017

In this paper we investigate gender wage disparities in 25 EU countries before and after the crisis, focusing on the role employment protection legislation played in shaping the gap across the wage distribution. Results of quantile regressions reveal a remarkable cross-country diversity in the size of the gap and confirm the widespread existence of glass-ceiling effects. Stricter rules for temporary contracts mitigate the gender gap, especially at the top of the distribution; stronger protection for permanent workers is found to increase the gap at the bottom of the distribution and to decrease it at the middle and at the top.
Characterising and testing European business cycles asymmetry
Authors: Kovacic Zlatko J. , Vilotic Milos
Published: November 2017

Research background: One of business cycles stylised facts is that contractions are shorter than expansions, but less persistent, more volatile, and therefore asymmetric. Investigating existence and type of business cycles asymmetry is important for analysis of economic policy and statistical modelling. Economic implication of business cycles asymmetry is that economic policy should be different in a period of contractions than in one of expansion. Statistical implication is that linear models of business cycles cannot capture this stylised fact.

Purpose of the article: The article has two objectives: extend the literature on the business cycles asymmetry by testing data from 36 European countries including countries never been analysed before and test robustness of the results to extraction methods and asymmetry tests used.

Methods: Quarterly GDP series from Eurostat database covering period 2000q1?2016q3 were used with two exceptions. In the case of Bosnia and Herzegovina and Montenegro quarterly industrial productions indexes were used. Series were prepared by removing seasonal component using X13-ARIMA procedure. To assess robustness of asymmetry tests results to alternative methods of detrending business cycles were extracted using two filters: Corbae-Ouliaris ideal band filter and double Hodrick-Prescott filter. For testing the deepness and steepness asymmetry of the business cycles three tests were used: Mills, Mira and Sichel tests.

Findings & value added: Weaker evidence of deepness asymmetry was found in Cyprus, Montenegro and Turkey cycles, where all three tests statistics for both filters have a negative sign. However, only for one of the tests in each country the result was statistically significant. For two other countries, Germany and Sweden, four out of six tests indicated deepness asymmetry, but only one of these tests results was statistically significant. Most of the cycles show steepness asymmetry, with the exception of Ireland business cycles, and to a certain extent cycles of Poland, Malta, Montenegro and Spain.

Published: October 2017

The article deals with basic morphological hematological characteristics of the three-year-old European perch ( Perca fluviatilis ) living in artificial conditions (1 m3 water tank). In the research there were used biological, histological and statistical methods. Erythrogramswerecalculated for 1000 erythrocytes; leukograms - for 200 leukocytes. In all samples taken in different periods (spring, summer, autumn, winter) there were registered different stages of erythrocyte development (erythroblasts, oxyphilic normoblasts, polychromatophilic normoblasts). Erythropoiesis activity in tested species was registered in spring (1.89%), in oxyphilic normoblasts (40.8%) in early autumn, when oxygen concentration in the water tank lowered due to high water temperature. In the course of testing in all samples there were registered certain morphological changes in the cells of erythrocyte series, such as poikilocytosis, displacement of the nucleus to the cell periphery, schistocytosis, non-nuclear cells, anisocytosis, oligochromasia, deformation of the nucleus. Poikilocytosis occurred most often. There were found piriform, falciform, rhomboid, polyhedral shaped cells; erythrocytes with outgrowths specific for erythropoiesis suppression were scares. Representatives of the leukocytes were lymphocytes, monocytes and a small number of precursor cells of granulocytes (myelocytes, promyelocytes). The predominant component of leukocyte form perch were represented by lymphocytes. Eosinophil and basophil cells in blood films were little. The number of thrombocytes for 1000 erythrocytes (0.92-1.59 depending on the season) testify sound state of fish species.

Published: November 2017

Thecharacter of coir handsheets prepared with beating and addition of polyamideamine-epichlorohydrin (PAE) was investigated. Pulp coir from soda-anthraquinone pulping was used as raw material for manufacture of coir handsheets. Physical and mechanical properties obtained with different beating level and PAE dosage were measured. The addition of PAE 10% w/w and beating on pulp stock of 3000 rev increased grammage and density at 1.9 and 15.8%, respectively. Instead it decreased thickness by 15.8%. Addition PAE dosage of 10% w/w at 10000 rev improved the density, but decreased the porosity and Cobb60 at 5.8; 10.2; and 19 %, respectively. The highest   dry and wet tensile were obtained at 20 % w/w of PAE. Combination of  beating and addition of PAE on pulp stock formed wet-strength handsheets with range between 28.0 to 34.2%.

Infectious diseases have become one of the leading cause of mortality around the world, including in the Southeast Asia. One of the microbial that cause infection is fungi. Occasionally, deep-seated fungal infection is difficult to detect using conventional diagnosis methods and therefore leads to inaccurate detection. Our previous research was conducted in order to obtain the labeled compound of 99mTc-DTPA-Ketoconazole with a high radiochemical purity (98.40 ± 0.86%). Moreover, the in-vitro assays showed that 99mTc-DTPA-Ketoconazole can potentially bind to Candida albicans. On the other hand, in clinical routine use, diagnostic kit should be safe for the patients. Consequently, this research was conducted to determine the biological safety parameters of 99mTc-DTPA-Ketoconazole on the animal study, including single dose and acute toxicity test, sterility, and apirogenicity test. The results showed that both the single dose at 34.6 μCi and dose until 149 times of the single dose did not stimulate the toxic response to the animals. In addition, the sterility data revealed that there was no microbial growth after 7 days of incubation at 37°C as well as fungal growth after 14 days of incubation at 25°C. Furthermore, the apirogenicity test using rabbits revealed that there was no increase in temperature more than 0.6°C for each animal and not more than 1.5°C of total increase of temperature for all the animals. It is concluded that the 99mTc-DTPA-Ketoconazole is satisfy the requirements of biological safety of a radiopharmaceutical and therefore was acceptable for fungal detection in nuclear medicine.

Published: November 2017

Simulation using Monte Carlo code has been conducted to determine the distribution of absorbed dose to the breast brachytherapy with 131Cs and 103Pd radionuclide sources. Simulations performed on stage I breast cancer with cancer diameter is 2 cm. Sources of radionuclides simulated in the form of seed is modeled with CS-1 which is made by IsoRay 131Cs and seed ADVANTAGETM103Pd which is made by IsoAID, LLC. Seed was planted in breast cancer cells. Calculation of absorbed dose distribution was performed by varying the distance from the seed. Variations of the distance started from a radius of 0.3 cm to 2 cm with a range of 0.1 cm respectively. In this simulation will also be reviewed the value of absorbed dose for healthy cell like breast, sternum, and lung. The relation between the absorbed dose and the distance from the seed can be described in the form of power law. The results of the calculation show that the maximum absorbed dose is in the target site of the cancer cells (5.791 ± 0.002) Gy per 5 MBq of 131Cs and (2.755 ± 0.009) Gy per 5 MBq for 103Pd. The absorbed dose at sternum (1.514 ± 0.011) x 10-4 Gy per 5 MBq of 131Cs and (7.515 ± 0.633) x 10-7 Gy per 5 MBq for 103Pd. While the absorbed dose in the lungs is and (3.615 ± 0.082) x 10-5 Gy per 5 MBq for 131Cs and (3.972 ± 0.591) x 10-8 Gy per 5 MBq for 103Pd.

O assédio moral é um fenômeno que atinge a dignidade, a personalidade, a integridade física e psíquica do trabalhador por meio de atos, gestos, palavras e comportamentos degradantes de forma sistemática e prolongada. Neste contexto, buscou-se observar o papel do empregador na aplicação das leis trabalhistas existentes para proteger a saúde dos trabalhadores, apesar de não haver norma específica relacionada ao fenômeno que se reflete fortemente hoje no ambiente laboral, assim como uma possível adoção de uma política de luta contra o assédio nas organizações. Foram analisadas as limitações teóricas e práticas do assédio moral, segundo as fontes doutrinárias e jurisprudenciais, as leis estaduais, municipais e projetos de leis que buscam regular o instituto, bem com a recém publicada lei nº 13.185/2015, que Instituiu o Programa de Combate à Intimidação Sistemática. Igualmente a necessária eficácia dos direitos fundamentais consagrados na Constituição da República, como o princípio da dignidade humana, bem como a norma ordinária trabalhista, a CLT.
Categorias da antijuridicidade: ato ilícito e ato abusivo

Published: October 2017

O presente estudo busca analisar as categorias da antijuridicidade, ou seja, o ato ilícito em sentido estrito, bem como o ato abusivo, que também é chamado de ilícito em sentido amplo. Para tanto, busca-se as definições de ambas as categorias de ato ilícito, e além disso, suas diferenciações. Nesta diretriz, verifica-se que o ato ilícito em sentido estrito, pode-se caracterizar em seu aspecto subjetivo, quer dizer, neste ponto exige-se o elemento culpa para sua configuração. Portanto, há ainda, o ato ilícito não culpável que se fundamenta na teoria objetiva (P.Ú., art. 927, CC), que ocorre independentemente do elemento subjetivo (culpa). Por outra vertente, o ato abusivo (art. 187, CC) – em sentido amplo - se traduz quando o titular de um direito que, ao exercê-lo, excede manifestamente os limites impostos pelo seu fim econômico ou social, pela boa-fé ou pelos bons costumes. A partir daí, busca-se entender os efeitos dos atos ilícitos e suas consequências. Neste aspecto, verifica-se a preferência da tutela preventiva face a tutela repressiva.

Published: October 2017

This paper assesses the impact of peri-urbanisation on housing, environmental quality and residents’ socio-demography in Ibeju-Lekki peri-urban in Lagos, Nigeria. Primary data was collected through administration of 370 questionnaires to household heads in purposively selected sixteen settlements in the study area while secondary data was sourced from spatial images, land use maps and satellite images of the study area. Quantitative data were analysed using descriptive statistics while qualitative data was analysed using time series and satellite image analysis. The result shows a spatial expansion due mainly to increased housing development, a multi-dimensional environmental and socio-cultural challenges that impact negatively on the quality of living and a literate, high-income group dominance in the selected peri-urban settlements in Ibeju-Lekki. The study recommends the creation of a database to capture the pattern of housing development, residents’ socio-economic demography and infrastructure needs for intervention in policy design for sustainable development.
CHARACTERISTICS OF MECHANICALLY FRACTIONATED AGGREGATES OF TWO CONTRASTING SOILS

Published: November 2017

Tillage often decreases physical condition of agricultural land, especially aggregate degradation which causes land and environmental quality decreased. As aggregates disperse into single particles, chemical properties of the soil could change. The objective of this research was to study whether or not mechanical fractionation causes soil dispersion indicating by different chemical properties. Aggregates of two soils, Vertisol and Oxisol, were degraded by using puddler at 3 different energy rates (40, 60, and 150 J kg-1 soil minute-1) and then were separated into 3 different sizes (2000-20, 20-2, <2 um). Therefore, each soil sample would have 15 soil separates at different energy and aggregate size. The result showed that aggregate fractionation especially the fraction size, in general, affected EC, ESP, and CEC but not pH of both soils. The pattern of EC and CEC values seemed to be equal, the highest values were found at the smallest aggregate size (< 2 um). The CEC values of Oxisols did not affected by fractionation, while CEC values of Vertisols increased by decreasing aggregate size, and decreased by increasing energy applied. This indicated that Vertisol is easier to disperse than Oxisol.

Study on decomposition rate of accumulating and excluder tree species of calsium (Ca) was conducted in a super wet tropical rain forest in Gadut Mountain Padang West Sumatra. The purposes of the study were : (1) to understand the rate of decomposition of biomass of Ca accumulating and excluder tree species, (2) to understand the effect of slope position (ridge, midle and lower slope) on decomposition rate within the study plot and (3) to understand the amount of nutrient release to soil ecosystem within certain period. The result of this study showed that the higher decompoisition rate among two species was Eugenia sp, as Ca accumlating tree species which grew at lower slope. Six months after decomposition, 1 ton dry biomass of Eugenia sp contributed 6,8 kg N, 0,4 kg P, 4,12 kg K, 38,76 kg Ca, and 2,1 kg Mg in to the soil. This amount might keep an equilibrium of soil nutreint balance to support the forest ecosystem. However, for one ton dry mass of Lithocarpus korthalsii sp as Ca exluder tree species, after 6 months decomposition, contributed 9,4 kg N, 1,1 kg P, 4,61 kg K, 3,76 kg Ca and 0,54 kg Mg. This indicates that Ca acumulating tree species contributed more Ca compared to Ca excluder tree species in this forest ecosystem. Keywords: Accumulating tree sp., exluder tree sp., decomposition rate, super wet and tropical rain forest.

The research was aimed to determine land suitability for manggis (Garcinia mangostana L) as a type of conservative crops in seven regions in District of Lima Puluh Kota. Survey method with purposive random sampling was employed at this study. Soil samples were randomly taken in each region for the physical and chemical analyses in laboratory. Secondary data for climate were obtained at Agriculture Department of the District. Both soil and climate data were arranged and interpreted for manggis growth requirement. The result showed that actual land suitability for each region was classified into S2-S3, with limiting factors were availability of plant nutrients and water, as well as topography. However, by improving soil fertility through OM application as well as soil conservation action, potential land suitability could be increased to be S2-S1 as in Guguk and Bukit Barisan.Keywords: land suitability, soil conservation, manggis

Research on biodiversity of  N-fix bacteria was performed on rhizosphere  of Tithonia diversifolia grown at acid soil Ultisol. This study aimed to determine the biodiversity and populations of N-fix bacteria along with the growth rate of Tithonia and characterized the bacterial isolates obtained from the rhizosphere of this plant. Soil rhizosphere samples were taken from rhizospheres of Tithonia with different criteria of stem diameter i.e Ø <3 cm, and 3 to 6 cm that grown  at Faculty of Agriculture Andalas University experimental station.From these results it can be concluded that the diverse and larger population were  found in Tithonia with 3 to 6 cm stem diameter  an average of 19.7 x 103 cfu per g of soil. N-fix bacterial isolates obtained have a round, slimy, slippery and convex colonies and gram variable. Based on the color of their colonies, N-fix bacterial isolates obtained were classified into 3 groups with the following characteristics: (1) white milk isolates (A1ps, a2ps, B3ps), flourescent white and yellow, have flagella and produce auxin, (2) yellow isolate (B2K and B3K), with yellow flourescent, have flagella and produce auxin, and (3) the clear isolates that could separated into two groups i.e the flourescent group and produce auxin and has flagella isolates (A2b, A3b, and B2b) and non flourescent group, no flagella and does not produce auxin isolates (B1b, B3B). The optimum growth conditions for the all isolates were pH media nearly 7 with 35o C incubation temperature. The translucent isolates (A3b and B3B) have a optimum range pH from 4.36 to 6.17, while isolates with a yellow colonies (B2K) has a range of incubation temperature 25oC to 35oC. However, from the characterization performed could not permit to specify the isolates obtained into species.Key words : Biodiversity, N-fix bacteria, rhizosphere, Tithonia diversifolia
