Published: June 2020

Shipment of container has become a phenomenon in the world of logistics it is seen as more efficient and effective means of transportation. Changes in shipment patterns from break bulk cargo to containers also occur in the port of Perawang along with the construction of bridges in Siak Sri Indrapura so that large vessels can no longer enter and carry out loading and unloading activities at the Perawang port, and this has resulted in companies having to invest in mechanical equipment because ships that enters the perawang private jetty is no longer supported by the crane on the ship.

Based on data owned by PT. Indah Kiat Perawang container shipments continue to increase from year to year but not accompanied by an increase in the number of labor. This study aims to see the effect of Container Shipment, Mechanical Equipment Investment and Labor Wages on Labor Demand at perawang port. This study uses secondary data with data from 12 semesters from 2013 to 2018. With independent variables namely Container Shipment, Investment and Wages. The analysis technique used is multiple regression. The results of the research shows that container shipment and investment has no significant effect on labor demand, whilts wages has a significant and negative effect on labor demand

Constructing Foreign Policy vis-à-vis the Migration Crisis
Authors: Tabosa Clarissa
Published: June 2020

The study examines contemporary discourses in two small CentralEuropean states, Slovakia and the Czech Republic. The aim is to analyzehow key domestic political players discursively construct foreign policy vis-à-vis the migration crisis. Securitization, a concept developed by theCopenhagen School, serves as an analytical framework for revealing thekinds of discourse being produced in the two countries. The analysis of thediscourse of the Prime Ministers from 2015 to 2018, indicates that in theCzech Republic and Slovakia foreign policy is being constructed around theissue of Europeanness (belongingness) and accommodation in the core-periphery spectrum. The article shows that the construction of externalthreats is done in different security sectors in each country, but in both itseems to promote the in-group coherence needed to affirm theirbelongingness to Europe, and it no longer happens on grounds of ethnicallydefined nations, but on grounds of the broader idea of civilizational Europe.
Estonian Identity Construction Between Nation Branding and Building

Published: June 2020

Whilst most accounts of nation branding emphasize the economic anddiplomatic relevance of the phenomenon, this article examines the wayEstonia has been proposing a nation “branding + building” strategy.Drawing from an empirical study of 1) evolving campaigns of EnterpriseEstonia; 2) the leverage of the national e-Residency program in attractingforeign investment; and 3) tourist and marketing strategies based on therevisiting of ‘Estonian’ culinary tradition, we look at the way officialnarratives have been claiming, with the help of nation branding elements,that the country has quickly de-Sovietized and that there is a newunderstanding of the Estonian nation and “Estonianness”. This is intendedto eventually prompt a reflection on the relationship between nation-building and nation branding, which can, in some circumstances, overlapand influence identity construction at the domestic and international level.
Julien Chaisse (ed.): China's International Investment Strategy: Bilateral, Regional, and Global Law and Policy
Authors: Svoboda Ondřej
Published: June 2020

The phenomenal story of China’s ‘unprecedented disposition to engage theinternational legal order’ has been primarily told and examined by politicalscientists and economists. Since China adopted its ‘open door’ policy in1978, which altered its development strategy from self-su!ciency to activeparticipation in the world market and aimed at attracting foreigninvestment to fuel its economic development, the underlying policy formobilizing inward foreign direct investment (IFDI) remains unchanged todate. With the 1997 launch of the ‘Going Global’ policy, an outward focusregarding foreign investment has been added, to circumvent trade barriersand improve the competitiveness of Chinese firms, typically its state-ownedenterprises (SOEs). In order to accommodate inward and outward FDI,China’s participation in the international investment regime hasunderpinned its efforts to join multi-lateral investment-related legalinstruments and conclude international investment agreements (IIAs).China began by selectively concluding bilateral investment treaties (BITs)with developed countries (major capital exporting states to China at thattime), signing its first BIT with Sweden in 1982. Despite being a latecomer,over time China’s experience and practice with the international investmentregime have allowed it to evolve towards liberalizing its IIAs regime andbalancing the duties and benefits associated with IIAs. The book spans abroad spectrum of China’s contemporary international investment law andpolicy: domestic foreign investment law and reforms, tax policy, bilateralinvestment treaties, free trade agreements, G20 initiatives, the ‘One BeltOne Road’ initiative, international dispute resolution, and inter-regimecoordination.
Factors that Shape the Demand for International Football Games Across Different Age Groups
Authors: Bergmann Andreas , Schreyer Dominik
Published: June 2020

Abstract: In recent years, the composition of revenue sources has changed substantially for professional football clubs, thereby leading to a significant dependency on broadcasting income. Accordingly, economists, traditionally more interested in the economic analysis of football stadium attendances, have begun turning their attention to the potential determinants of television audience demand in professional football. Despite this rapidly increasing interest of economists in exploring the determinants of football TV demand, there is, however, little empirical evidence on the stability of such determinants across different age groups. This article addresses this notable research gap. More specifically, analyzing the German TV demand for 174 international football games played by the German national football team between season 2004–2005 and 2016–2017, our exploratory study reveals that the determinants of international football demand are not necessarily robust across all age groups.
The National Football League and Efficient Market Hypothesis: An Analysis of Trends in Thursday Night Football and Post-Bye Week Games
Authors: Sung Yoon Tae
Published: June 2020

Abstract: This study investigates the efficiency of National Football League betting markets from 2002 to 2015 utilizing three rest patterns (Thursday Night Football, post-bye week, and regularly scheduled games). The logistic model indicates that inefficiencies due to the rest patterns occurred in Thursday Night Football and post-bye week games, with bettors expecting high rates of return. The forecast errors also provide evidence that point spreads did not correctly forecast future outcomes. Nevertheless, this deviation from efficiency was not sufficient to make positive returns from Thursday Night Football when teams of record were tested separately. A bias from post-bye week games remained profitable across the studied years, suggesting previously confirmed biases were not temporary. Although further analyses with a larger sample size are needed to confirm whether Thursday Night Football creates a bias consistently, this study suggests that the betting market misses important information about rest intervals and team performance.

Published: June 2020

A significant influence of dietary and nutrition transition is on the food behaviour of populace reflected in higher dependence on processed or catered foods. The traditional home cooked meals have been largely replaced by street or restaurant foods. While the nutritional composition of processed foods is declared on the label, there is no such information available regarding catered foods and the consumer cannot make an informed choice while selecting food at an eatery. With this premise, the present study was undertaken to analyse the nutritional composition of selected meat and vegetables based Indian dishes sourced from three different catering establishments. Similar dishes were also prepared in laboratory and the nutritional value computed using food composition database. The dishes selected were curries made with chicken, mutton, fish, mixed vegetable, Malai kofta (potato and cheese balls in creamy gravy) and Gobi Manchurian (deep fried spiced cauliflower snack). The results revealed that there were wide variations in the energy and fat content of foods sourced from different eateries. In general, the fat content of dishes was very high. In comparison, laboratory prepared items had lesser energy and fat content. The information will help in creating a nutrient database of ready-to-eat foods and help the consumer in selectin of dishes.
A Educação Integral no contexto do Ensino Médio

Published: June 2020

O presente trabalho tem como objetivo refletir sobre como a Educação Integral tem sido implementada no contexto do Ensino Médio Brasileiro. Tem-se como problema de pesquisa a discussão acerca dos principais desafios encontrados para fornecer um ensino, de fato, integral, sem que haja o esgotamento do aluno. Parte-se de hipótese de que não adianta apenas enfocar nas horas em que esse aluno irá permanecer nessa escola. É preciso que todas as capacidades cognitivas sejam trabalhadas para que haja uma formação integral do alunado. Esse é o grande desafio: fazer com que as horas a mais na escola acarretem a formação integral a partir de atividades pedagógicas eficientes. A Educação Integral é uma proposta do governo federal que traz, em seu arcabouço, a possibilidade de oferecer uma educação de qualidade que contemple o educando em sua integralidade. Trata-se de ampliar o tempo e espaço do educando no ambiente escolar e agregar a esse contexto diversos componentes curriculares que possam complementar o conhecimento já adquirido em sala de aula. Todavia, para que os resultados possam ser efetivamente alcançados, é importante que alguns passos sejam dados, como, por exemplo, a reestruturação das escolas e a qualificação docente para lidar com a inclusão destes saberes. Não é uma tarefa fácil, pois requer recursos financeiros para organizar e adequar o espaço para todas as possibilidades educativas, bem como carece do empenho e envolvimento de toda a equipe da escola, principalmente dos docentes, no sentido de apreender o significado da educação integral e colocar em prática as possibilidades de ensino e aprendizagem.

Published: June 2020

A Leishmaniose é uma doença negligenciada causada por protozoários do gênero Leishmania spp., o qual atinge cerca de 1,6 milhão indivíduos a cada ano sendo que 500 mil se apresentam na forma visceral. No Brasil ocorrem cerca de 30.000 novos casos a cada ano. Além disso, o país é responsável por 90% dos casos notificados de Leishmaniose Visceral, sendo essa forma mais grave da doença. Aliado a esses fatos, o tratamento vigente se mostra ineficaz, contribuindo para o estabelecimento de cepas resistentes. Atualmente, o tratamento apresenta diversos efeitos colaterais e danos permanentes à saúde dos pacientes, tal fato têm contribuído para a procura de novos fármacos contra a leishmaniose. A enzima oligopeptidase B (OPB) tem sido estudada como possível alvo terapêutico no desenvolvimento de agentes antiparasitários. Desta forma, o objetivo desse trabalho é construir o modelo tridimensional da enzima Oligopeptidase B de diferentes espécies de Leishmania spp. e compara-las entre si. Para tal, foi utilizado o método de modelagem comparativa. Nesse método foi feita a construção dos modelos das espécies L. brasiliensis, L. donovani, L. infantum, L. mexicana e L. panamensis, utilizando o programa MODELLER. Uma vez com os modelos prontos foram realizados o processo de validação dos mesmos e subsequentemente caracterizados, o qual foi possível constatar um grau de semelhança promissor entre os modelos. Por fim, tais modelos foram submetidos ao método de análise por modos normais, os quais obtiveram um padrão de movimento semelhante, com isso foi possível constatar um movimento em uma região específica de uma alfa-hélice, levando consequentemente a tríade da enzima se mostrar exposta, podendo ser indicativo de um mecanismo de ação. Por fim, espera-se utilizar os modelos construídos para auxiliar no desenvolvimento de uma nova terapia promissora para o tratamento da leishmaniose.

Authors: Barbosa Paulo Henrique de Jesus , Benites Cristiano da Silva
Published: June 2020

Este trabalho mostra Um Novo Método para Qualificação de Lesões da Mama Baseado na Transformada Ripplet. O câncer de mama é o tipo de câncer mais comum entre as mulheres no mundo e no Brasil, depois do de pele não melanoma. Com os avanços na geração de bancos de dados de tecidos e de estudos histológicos digitalizados, é possível utilizar padrões de tecido histológico com análise de imagem assistida por computador para facilitar a classificação da doença. O objetivo deste trabalho foi investigar um método de extração de descritores de textura, a partir dos coeficientes da transformada Ripplet-II; investigar grupos de descritores, combinando os coeficientes das transformadas com as características estatísticas de segunda ordem; estudar o algoritmo ReliefF na seleção de descritores de textura relevantes para classificação com algoritmo Random Forest; identificar quais as características mais apropriadas para classificar os diferentes tipos de lesões de mama; e analisar os resultados e comparação com outras abordagens presentes na literatura. A metodologia deste trabalho foi a escolha de imagens de bases histológicas de lesões para extração das características; preparo das imagens através dos procedimentos de pré-processamento, para melhorar a relação sinal/ruído dessas lesões; aplicação da transformada Ripplet-II para extração de descritores e suas variações em sub-bandas; extração de características estatísticas de segunda ordem manipuladas nos conjuntos de combinações de grupos de características; execução de algoritmo para seleção de características, eliminando assim ruídos e características não relevantes; aplicação dos classificadores para avaliação dos grupos de descritores. Diante dos resultados encontrados na literatura, para identificação de lesões em imagens histológicas de mama, utilizando outras abordagens, muitas delas complexas, pode-se destacar que este trabalho apresentou resultados promissores com o uso dos coeficientes da Ripplet-II, numa abordagem simples. Conclui-se que o desempenho do método proposto foi melhor utilizando-se as imagens da base UCSB, fato este comprovado também pelos índices obtidos pelos trabalhos existentes na literatura, ou seja, enquanto as análises com as imagens da base UCSB alcançam patamares superiores a 95% de acurácia, com a BreakHis atinge valores em torno de 90%.

Among skin cancers,

melanoma has the highest mortality rate. The heterogeneous genetic melanoma

background leads to a tumor-propagating capacity particularly important in

maintaining therapeutic resistance, and tumor recurrence. The identification of

efficient molecules able to control melanoma progress represents an important

opportunity for new therapeutic strategies, particularly in combination with the

current standard-of-care treatments. In this context,

several studies have reported the antitumor effects of melatonin against

different types of cancer, including melanoma. Here,

we describe the underlying mechanisms associated with melatonin’s activity in

human melanoma cell lines, focusing on cell cycle and cytoskeleton

remodeling. Interestingly, while melatonin induced melanocyte

DNA replication, melanoma cells exhibited cell cycle arrest in the G1-phase.

This phenomenon was associated with cyclin-D1 downregulation or p21

overexpression. The efficacy of melatonin on melanoma cells survival and

proliferation was detected using the clonogenic assay, with a decrease in both

the number and size of colonies. Additionally, melatonin induced a dramatic

cytoskeleton remodeling in all melanoma cell lines, leading to a star-like

morphology or cell swelling. The role of melatonin on melanoma cytoskeleton was

associated with the actin disruption, with thinning and/or broken actin fibers,

and weak and/or loss of paxillin along stress fibers. These data support the

observed findings that melatonin impairs melanoma invasion in skin

reconstructed models. Together, our results suggest that melatonin could be

used to control melanoma growth and support basic and

clinical studies on melatonin as a promising immunometabolic

adjuvant for melanoma therapy.
Melatonin supplementation protects against the benzo(e)pyrene cytotoxicity and optic cup formation disruption in chicken embryos

Published: June 2020

Benzo(e)pyrene is a cytotoxic chemical to the

eyes, while neurohormone melatonin may exhibit protective effects on this

cytotoxicity. In the current study, we have investigated the cytotoxic effects

of benzo(e)pyrene on the chicken embryonic optic cups formation and whether

melatonin supplementation protects chicken embryos against this xenobiotic

toxicity. Fertilized chicken eggs were incubated for 48 h and then, they were

divided into different groups. These groups included basal (without any

treatment), control (distilled water), benzo(e)pyrene, melatonin and

benzo(e)pyrene + melatonin groups, respectively. The 10 µl of distilled water

or same volume of solution containing treatment compounds were injected into

the air sac of the chicken egg. After an additional 18 h of incubation, the

chicken embryos were excised and analyzed. The cytotoxicity was measured by a

colorimetric whole chick embryo trypan blue assay. In embryos from basal,

control and melatonin (0.01, 1 and 100 µM) groups, the frequency of the embryos

with normal optic cups was 100% and had no increase in the embryonic cell death

observed in post excision. In contrast, the frequency of normal optic cups in the

benzo(e)pyrene (0.02 to 1200 µM) groups was significantly reduced (log IC50=

-4.24 ± 0.02, R2= 0.98) with concentration-responsive manner. In

addition, an increase in the embryonic cell death was also observed (log IC50 =

-7.23 ± 0.28; R2 = 0.63). Melatonin treatment dose-responsively inhibited

the benzo(e)pyrene-induced optic cups abnormality by 22.35 ± 4.06, 76.38 ± 3.30

and 100 % at the concentrations of 0.01, 1 and 100 µM, respectively. This same

phenomenon was also observed in benzo(e)pyrene-induced embryonic cell death,

i.e., melatonin suppressed the embryonic cell death by 16.67 ± 4.17, 54.17 ±

4.17 and 100 % with the abovementioned concentrations, respectively. Thus, melatonin

supplementation injected into the chicken eggs protected against the

benzo(e)pyrene embryotoxicity. Different pathways can be involved in melatonin’s

protective effects.
Hydromagnetic Stability Analysis of a Partially Ionized Medium
Authors: Kumar Pardeep , Mohan Hari
Published: June 2020

Rayleigh-Taylor instability of a composite medium with variable density and viscosity is considered by taking into account the frictional effect of collisions of ionized with neutral atoms in the presence of a variable horizontal magnetic field. The criteria determining stability and instability are independent of the effects of viscosity and collisional effects. The magnetic field stabilizes the system which is otherwise unstable in the absence of the magnetic field. The viscosity of the medium has stabilizing as well as destabilizing effect on the growth rates. The collisional frequency has stabilizing effect on the growth rates, but has also destabilizing effect in some region.
Influence of Organic Dye Ligands on the Photocatalytic Reduction of Copper Ions in Aqueous Solution Using UV-Nano TIO2 System
Authors: I. O. Ekwere
Published: June 2020

This study investigates the influence of some organic dyes on the photocatalytic reduction of Cu (II) ions in aqueous solution. The dyes of interest were Eosin red, Eriochrome black T, Bromothymol blue and Malachite green. Slurry photoreactor design, with nano-sized titanium dioxide photocatalysts, and illuminated by a 15 W UV light, was utilized. Results showed that the percentage reduction of Cu (II) ions altered from 44.7% (without dye) to 25.7% (with ER), 60.7% (with EBT), 15.2% (with BTB) and 17.8% (with MG) after 60 minutes reaction time at pH 5. This implies that EBT enhanced Cu (II) ions reduction while the other three dyes inhibited the photoreduction process. The kinetic study indicated that the photo-reduction of Cu (II) ions followed the pseudo-first-order kinetics, with the exception of Cu-MG reduction which gave the best correlation values in zeroth-order plot. Statistical analysis was carried out with the ANOVA, Dunnetts post-hoc and Tukeys post-hoc multiple comparison tests. Tukeys post-hoc multiple comparison test was effected to determine the pair of Cu (II) ions with significant difference in mean values while Dunnetts post-hoc was effected to compare the measured values with the initial values. Photoreduction of Cu (II) ions were considered significant at P< 0.05 and 95% confidence interval.

Interwencyjne aspekty fotografii reporterskiej
Authors: Szcześniak Karolina
Published: June 2020

Cel/teza: Analiza mechanizmów wieloaspektowego przekazu medialnego fotografii reporterskiej w perspektywie interwencyjności. Autorka rozważa znaczenie funkcji interwencyjnej w fotodokumentalnych przedstawieniach wizualnych, w kontekście kontaminacji znaczeń kodów kulturowych i społecznych. Podkreśla, że w medioznawstwie fotografia reporterska może służyć do badania oddziaływania mediów na odbiorców przez emocjonalność, perswazyjność oraz apelatywność. Metody badań: Autorka dekoduje treści fotografii reporterskiej w kontekście znaków metonimicznych i synekdochalnych, które są skorelowane z funkcjonalno-pragmatycznym ujęciem tych przekazów medialnych. Wyniki i wnioski: Interwencyjność fotografii reporterskiej jest zwykle wartością potencjalną, może zwiększać świadomość i odpowiedzialność społeczną. Fotoreportaże o wyraźnej funkcji interwencyjnej spełniają również rolę aktywizującą społecznie odbiorców. Jednak celem prymarnym dziennikarskiej fotografii interwencyjnej pozostaje przede wszystkim naprawa zastanej rzeczywistości i zapobieganie negatywnym zjawiskom społecznym. Wartość poznawcza: Problem interwencyjności medialnych przekazów fotograficznych był rzadko poruszany w badaniach społeczno-kulturowych. Studium poświęcone interwencyjności massmedialnych fotodokumentów wpisuje się w szerszą dyskusję dotyczącą interpretacji kultury wizualnej w kontekście receptywnego rezonansu społecznego.

Wyniki i wnioski: W wyniku przeprowadzonych badań ustalono, że blogerzy technologiczni konstruują własną rzetelność w oparciu o wyraźne wyróżnienie treści reklamowych w tworzonych przekazach, zawieranie umów partnerskich i sponsorskich wyłącznie z firmami, które nie dostarczają technologii, autentyzm osobisty oraz pewien stopień zbieżności ich działalności z regułami współczesnego dziennikarstwa. Wartość poznawcza: Przedstawione dociekania stanowić mogą punkt wyjścia dla dalszych analiz poświęconych zmianom w postrzeganiu statusu blogerów i dziennikarzy w środowisku sieciowym, a także przeobrażeniom polskiego rynku medialnego zachodzącym na skutek rozwoju zindywidualizowanej komunikacji masowej.

Published: June 2020

Young adults on college campuses have easy access to information and communications technology (ICT) which they use extensively for study, work, and leisure. The purpose of this study was to investigate the prevalence and extent of problematic Internet use, online gaming behavior, and online gambling behavior (together referred to as dysfunctional online behaviors), and their relationships with depression and quality of life among college students. Two hundred and twenty two valid surveys were used in the data analyses. Five instruments, Beck Depression Inventory-II (BDI-II), the WHO Quality of Life Scale-BREF (WHOQOL-BREF), the Internet Addiction Test (IAT), the Problematic Online Gaming Questionnaire (POGQ), and the Online Gambling Symptom Assessment Scale (OGSAS), were selected to measure the variables being studied. A non-experimental research design was employed to answer one descriptive and two research questions. The results of the analyses indicated that dysfunctional online behaviors predicted a higher level of depression (R2 = .14, p < .05) and a lower level of quality of life (R2 = .20, p < .05). The findings of the current study inform clinical practice and the treatment of dysfunctional online behaviors among college students.

DIÁLOGOS E CONVERGÊNCIAS ENTRE A AGROECOLOGIA E A CULTURA POPULAR CAMPONESA PARA A TRANSIÇÃO AGROECOLÓGICA BRASILEIRA
Authors: Cabral Caio de Meneses , Hernandéz David Gallar , Sanchez Isabel Vara
Published: June 2020

O objetivo deste estudo é apresentar a importância da relação entre a Cultura Popular Camponesa e a Agroecologia para o fortalecimento dos processos de transição agroecológica em distintos territórios e realidades brasileiras. Para isso, buscou-se apresentar experiências camponesas que utilizaram a cultura popular como ferramenta para desenvolver estratégias de resistência frente às distintas ameaças e desafios que enfrentam. O diálogo convergente entre esses dois campos representa a ampliação do fazer agroecológico na medida em que amplia e qualifica seu horizonte de ação, bem como visibiliza e reconhece a participação dos diversos sujeitos. Dessa forma, se por um lado a Agroecologia reconhecendo a Cultura Popular Camponesa tende a qualificar e fortalecer seu processo de transição agroecológica, por outro, em diálogo com a Agroecologia, os camponeses, a partir de sua cultura popular, apontam para um caminho estratégico para reafirmarem sua identidade e fortalecerem suas ações.
