SERVICE INNOVATIONS AND FIRM PERFORMANCE IN THE HOSPITALITY INDUSTRY: EVIDENCE FROM TOURISM DRIVEN ECONOMY
Authors: Stojčić Nebojša , Vojvodić Katija , Butigan Nikola
Published: September 2019

Purpose – The purpose of this paper is to identify the impact of service innovations on firm
performance in the hospitality industry in Croatia during the 2012-2014 period.
Methodology – The study uses data from the most recent round of Community Innovation Survey,
a confidential dataset compiled by Eurostat on innovation activities of firms in the EU member
states. With means of the nearest neighbour matching treatment analysis it first explores the
determinants behind the ability of firms to introduce service innovations before it explores whether
firms that introduce service innovations outperform their rivals.
Findings – The results of investigation suggest that service innovations emerge predominantly
through transfer of knowledge and skills between organizations, through intra-firm channels and
other spillover mechanisms. In addition, there is little evidence of internal organizational and
marketing innovations as drivers of innovation in services.
Contribution –Rising importance of services in world economy suggests that service innovations
are important for firm performance and competitiveness. To the best of our knowledge, there has
been no attempt to address determinants of innovation in general and service innovations in
particular in the hospitality industry in Croatia, whose economy largely depends on tourism, in
post crisis period. To this end, our study makes genuine contribution to the existing literature that
can translate into concrete policy recommendations.

Authors: Turkalj Davorin , Biloš Antun , Deželjin Renata
Published: September 2019

The growing interest of foreign tourists in Croatia's tourism offerings could be attributed to the
Croatian National Tourist Board (CNTB) increased promotional efforts, with special emphasis on
digital ones. Based on the data provided, the authors’ aim is to determine the state and potential of
utilizing online channels to enhance their effectiveness in online promotion. The data analyzed in
this paper enable the authors to suggest trends concerning the choice of digital platforms for
communication and intensity of further investments. Quantitative secondary data used and
analyzed in this paper are collected from the official CNTB website and also official annual
reports. The paper focuses on the period between 2014 and 2016, due to the introduction of
Croatian Strategic Tourist Marketing Plan 2014-2020 in 2014. The authors examine digital
promotion investments of the CNTB as well as the choice of individual digital communication
channels. The data presented in this paper enable authors to conclude if certain online promotion
investments were justified and to establish the number of visits that happened consequently. By
analyzing these data, it is possible to predict and advise a further increase in the latest forms of
digital promotion which would lead to better customer understanding of Croatia’s diverse tourism
offerings. Authors also recognize the rising importance of mobile presence when it comes to the
promotion of tourism products, services, and destinations.

Authors: Šuljić Petrc Alenka , Mikinac Krešimir , Edmonds Ivana
Published: September 2019

The purpose of this research is to analyse the current quality of menu translations in restaurants in
the Kvarner Region and to define the role of menus as a sales tool which can effectively influence
on restaurant's image and profit. The aim of this research is to answer the question of how quality
translated menus can help and contribute to better business and achieving customer satisfaction.
In this research the existing theories and models of translation strategies were analyzed, among
which a model for translation strategies that would be applicable to the Kvarner's restaurants. The
research also used analytical methods based on sources obtained through a desk research,
qualitative and quantitative methods to gather an in-depth understanding of how the existent
restaurant menus are translated, while analyzing their quality and finding the possibility of eventual
improvement.
The conclusion is that the menu’s aims consider communication and sales purposes, as well as
achieving customer satisfaction. According to these objectives, the improvement of restaurant
menu translations in foreign languages is needed. Quality translated menus are also a reflection of
restaurant’s image since they still serve the purpose of a business card that with its design, print,
size, food, and facility information represent a symbol of restaurant’s identity and theme.
The main contribution of the paper is the analysis of menu translations and present strategies for
translating which influence service quality and customer satisfaction. The research findings are an
important contribution to future research of menu translations and restaurant offer in the Kvarner
Region's restaurants.

Authors: Vasconcelos Sandra , Balula Ana
Published: September 2019

Purpose – As tourism has become a prominent industry, there has been a growing demand for
skilled professionals, who are able to adapt to technology-laden markets. In this setting, digital
development and communication take on an important role, making it necessary to reshape the
way tourism education is approached, focusing on the skills required of today’s graduates. English
is currently the most important global language and it is ranked as a crucial skill for tourism
workers. The main goal of this study is to collect, analyse and cross-reference evidence as to the
development of language and digital competences in Tourism Education and how they are
leveraging digital transformation.
Methodology –The methodology used was based on a literature review focusing on digital
technology in the scope of English for Specific Purposes (ESP). The data retrieved was analysed
as to outline key concepts and best practices within tourism education.
Findings – As the market requires tourism graduates to possess transversal skills, being fluent in
English is decisive. Research shows that tourism students need more exposure to technical jargon
and quality resources, as there are still significant gaps when it comes to using specific terminology
and vocabulary. With technology playing a pivotal role, it is important that tourism education
keeps up with current technological developments and changes.
Contribution – Tourism professionals should be proficient English users, capable of interacting,
understanding and communicating relevant information. Leveraged by digital technology, this
study makes a contribution towards the on-going discussion on the need to reshape tourism
education and update the curricula.

Authors: Veideman Triin
Published: September 2019

Purpose –The number of tourism choices is growing exponentially and quality is one of the most
important sources of competitive advantage for a destination, playing a critical role in attracting
both new and repeat arrivals. The purpose of this study is to explore the relationship between
implemented quality certification and online customer satisfaction. Destination Management
Organizations (DMOs) initiate quality certifications to regulate the market and help customers
make their purchase decisions. However, it is still unclear if there is a link between the certificates
awarded to an enterprise and the satisfaction of its customers. Small and medium tourism
enterprises (SMTEs) are used as a case study, applying distinctive focus compared to prior studies
concentrating on large hotels.
Methodology – An empirical analysis is carried out comparing 66 quality certified SMTEs with
169 non-certified SMTEs using secondary data derived from various online platforms.
Findings – Quality certification is an effective tool to achieve customer satisfaction as the findings
indicate that quality certified SMTEs receive higher online scores and increase the number of
online reviews after implementing the certification.
Contribution – This study contributes to the limited literature on quality management in tourism
sector investigating the connection between quality certification and online customer satisfaction.
The results from this research are presentable as guidelines for destination managers to advance
quality certification offered for SMTEs. In a market situation where digital technology is rapidly
changing the business environment for tourism sector.

Authors: Fedorak Graham T. , D’Astous Jacques L. , Nielson Alexandra N. , MacWilliams Bruce A. , Heflin John A.
Published: September 2019

Background:

With the exception of Mehta’s 2005 report on her experience treating early-onset scoliosis with serial casting, all subsequent studies have had limited follow-up. This current study sought to assess the results of serial casting at a minimum 5-year follow-up and to identify the predictors of the sustained resolution of scoliosis.

Methods:

This study is a retrospective review of children treated for idiopathic early-onset scoliosis with serial casting at a children’s hospital between 2001 and 2013 with a minimum 5-year follow-up. A Cobb angle of ≤15° and a decrease in the Cobb angle of >20° at the most recent follow-up were separately assessed. The differences between groups based on these criteria were tested with Student t tests with alpha = 0.05.

Results:

Fifty-four children were treated during the study period; of these, 38 had at least 5 years of follow-up and comprised the study sample. The mean follow-up (and standard deviation) was 8 ± 2 years (range, 5 to 13 years). The mean patient age at the time of the first cast was 24 ± 15.1 months (range, 9 to 63 months), with a mean Cobb angle of 56.2° ± 20.1° (range, 22° to 109°). Forty-nine percent of children had scoliosis of ≤15° at the time of the most recent follow-up, and 73% of children were improved by at least 20°. Children with ≤15° scoliosis, compared with children with >15° scoliosis, had significantly lower initial Cobb angle (48.2° compared with 63.7°; p = 0.016), supine traction Cobb angle (22.5° compared with 33.2°; p = 0.048), first-in-cast Cobb angle (24.1° compared with 37.6°; p = 0.01), and first-in-cast rib-vertebral angle difference (12.8° compared with 26.2°; p < 0.01). Age at the time of the first cast, initial rib-vertebral angle difference, flexibility, and body mass index were not significantly different (p > 0.05) between the groups. Three children who initially achieved scoliosis of ≤15° after casting substantially relapsed.

Conclusions:

At a minimum follow-up of 5 years, the initial Cobb angle, first-cast Cobb angle, rib-vertebral angle difference, and traction Cobb angle were all predictive of sustained scoliosis of ≤15°. However, with continued growth, relapse of scoliosis was seen in 3 patients.

The Association Between Race/Ethnicity and Revision Following ACL Reconstruction in a Universally Insured Cohort
Authors: Navarro Ronald A. , Prentice Heather A. , Inacio Maria C.S. , Wyatt Ronald , Maletis Gregory B.
Published: September 2019

Background:

There have been few large studies involving multiethnic cohorts of patients treated with anterior cruciate ligament reconstruction (ACLR), and therefore, little is known about the role that race/ethnicity may play in the differential risk of undergoing revision surgery following primary ACLR. The purpose of this study was to evaluate whether differences exist by race/ethnicity in the risk of undergoing the elective procedure of aseptic revision in a universally insured cohort of patients who had undergone ACLR.

Methods:

This was a retrospective cohort study conducted using our integrated health-care system’s ACLR registry and including primary ACLRs from 2008 to 2015. Race/ethnicity was categorized into the following 4 groups: non-Hispanic white, black, Hispanic, and Asian. Multivariable Cox proportional-hazard models were used to evaluate the association between race/ethnicity and revision risk while adjusting for age, sex, highest educational attainment, annual household income, graft type, and geographic region in which the ACLR was performed.

Results:

Of the 27,258 included patients,13,567 (49.8%) were white, 7,713 (28.3%) were Hispanic, 3,725 (13.7%) were Asian, and 2,253 (8.3%) were black. Asian patients (hazard ratio [HR] = 0.72; 95% confidence interval [CI] = 0.57 to 0.90) and Hispanic patients (HR = 0.83; 95% CI = 0.70 to 0.98) had a lower risk of undergoing revision surgery than did white patients. Within the first 3.5 years postoperatively, we did not observe a difference in revision risk when black patients were compared with white patients (HR = 0.86; 95% CI = 0.64 to 1.14); after 3.5 years postoperatively, black patients had a lower risk of undergoing revision (HR = 0.23; 95% CI = 0.08 to 0.63).

Conclusions:

In a large, universally insured ACLR cohort with equal access to care, we observed Asian, Hispanic, and black patients to have a similar or lower risk of undergoing elective revision compared with white patients. These findings emphasize the need for additional investigation into barriers to equal access to care. Because of the sensitivity and complexity of race/ethnicity with surgical outcomes, continued assessment into the reasons for the differences observed, as well as any differences in other clinical outcomes, is warranted.

Peripheral Nociception Is Associated with Voluntary Activation Deficits and Quadriceps Weakness Following Total Knee Arthroplasty
Authors: Loyd Brian J. , Stackhouse Scott K. , Hogan Craig , Dayton Michael R. , Stevens-Lapsley Jennifer E. , Kittelson Andrew J.
Published: September 2019

Background:

Quadriceps weakness is a hallmark of total knee arthroplasty and is driven by reduced voluntary muscle activation following the surgical procedure. The mechanisms underlying postoperative activation deficits are not well established, although nociception has been implicated via both spinal reflex and supraspinal pathways. The purpose of this study was to assess the role of nociception in postoperative recovery of strength and activation.

Methods:

A total of 53 participants were assessed prior to total knee arthroplasty and at 6 weeks postoperatively. Quadriceps strength was measured by maximum voluntary isometric contraction, and activation was measured by the doublet interpolation technique. The pressure-pain threshold was used to measure local sensitization (at the knee joint) and systemic sensitization (at the forearm). Changes in outcomes (strength and activation) were regressed against pressure-pain threshold measurements. Mediation analyses were planned for significant associations to investigate whether deficits in voluntary activation were implicated on a causal pathway between pressure-pain threshold measures and postoperative strength loss.

Results:

Knee pressure-pain threshold measures were significantly associated with reduced voluntary quadriceps activation (beta = −0.04; p = 0.009) and diminished quadriceps strength after total knee arthroplasty (beta = −0.07; p = 0.001). There was also a mediation effect of voluntary activation on the relationship between the knee pressure-pain threshold and quadriceps strength. After correcting for multiple comparisons, relationships between the forearm pressure-pain threshold and strength and activation did not reach significance.

Conclusions:

The measures of local nociceptor sensitization were related to reduced strength and activation following total knee arthroplasty. This is consistent with a causal pathway linking increased firing of knee joint nociceptors to reduced activation and reduced strength. Future randomized studies should investigate whether peripherally directed pain therapies reduce pain while also promoting the recovery of quadriceps strength via an improved capacity for voluntary activation.

Published: September 2019

Background: Staphylococcus aureus as a causative agent of hospital-acquired infections, has been considered as the primary concern in biomaterial-related infections (BAIs). Following the purification of polysaccharide intercellular adhesion (PIA) as an efficient macromolecule in biofilm formation in the native condition, recombinant S . epidermidis surface exposed rSesC protein, with the most homology to clumping factor A (ClfA) in S. aureus was cloned and expressed in a prokaryotic host as well. Fourier transform infrared spectrometry (FTIR) and Western blotting procedure analyzed purified PIA and protein, respectively. Then, the immune response was evaluated by measuring total IgG titers. Moreover, the capacity of Anti-biofilm forming activity of arisen antibodies to a biofilm forming S. aureus strains was assessed by semi-quantitative micro-plate procedure. Results: Data showed that the total IgGs was boosted in mice immunized sera. By performing inhibition assay, biofilm inhibitory effect of secreted antibodies to test strain was observed. Arisen antibodies against the mixture significantly were more potent than PIA and rSesC, when comparing them in a biofilm inhibition assay. Conclusion: Immunization of mice with mentioned antigens especially a mixture of them, could eliminate the biofilm formation process in S. aureus . Hopefully, this study corresponds the suggestion that, the immunization of mice with PIA and rSesC candidate vaccine could protect against S. aureus infection.
SURVIVAL REGRESSION MODELS FOR SINGLE EVENTS AND COMPETING RISKS BASED ON PSEUDO-OBSERVATIONS
Authors: Wycinka Ewa , Jurkiewicz Tomasz
Published: September 2019

Survival data is a special type of data that measures the time to an event of interest. The most important feature of survival data is the presence of censored observations. An observation is said to be right-censored if the time of the observation is, for some reason, shorter than the time to the event. If no censoring occurs in the data, standard statistical models can be used to analyse the data. Pseudo-observations can replace censored observations and thereby allow standard statistical models to be used.

In this paper, a pseudo-observation approach was applied to single-event and competing-risks analysis, with special attention paid to the properties of the pseudo-observations. In the empirical part of the study, the use of regression models based on pseudo-observations in credit-risk assessment was investigated. Default, defined as a delay in payment, was considered to be the event of interest, while prepayment of credit was treated as a possible competing risk. Credits that neither default nor are prepaid during the follow-up were censored observations. Typical application characteristics of the credit and creditor were the covariates in the regression model. In a sample of retail credits provided by a Polish financial institution, regression models based on pseudo-observations were built for the single-event and competing-risks approaches. Estimates and discriminatory power of these models were compared to the Cox PH and Fine-Gray models.

Authors: Abu Awwad Raed R. , Abufoudeh Ghassan K. , Bdair Omar M.
Published: September 2019

Based on one parameter exponential record data, we conduct statistical inferences (maximum likelihood estimator and Bayesian estimator) for the suggested model parameter. Our second aim is to predict the future (unobserved) records and to construct their corresponding prediction intervals based on observed set of records. In the estimation and prediction processes, we consider the square error loss and the Kullback-Leibler loss functions. Numerical simulations were conducted to evaluate the Bayesian point predictor for the future records. Finally, data analyses involving the times (in minutes) to breakdown of an insulating fluid between electrodes at voltage 34 kv have been performed to show the performance of the methods thus developed on estimation and prediction.
THE EFFECT OF BINARY DATA TRANSFORMATION IN CATEGORICAL DATA CLUSTERING
Authors: Cibulková Jana , Šulc Zdeněk , Sirota Sergej , Řezanková Hana
Published: September 2019

This paper focuses on hierarchical clustering of categorical data and compares two approaches which can be used for this task. The first one, an extremely common approach, is to perform a binary transformation of the categorical variables into sets of dummy variables and then use the similarity measures suited for binary data. These similarity measures are well examined, and they occur in both commercial and non-commercial software. However, a binary transformation can possibly cause a loss of information in the data or decrease the speed of the computations. The second approach uses similarity measures developed for the categorical data. But these measures are not so well examined as the binary ones and they are not implemented in commercial software. The comparison of these two approaches is performed on generated data sets with categorical variables and the evaluation is done using both the internal and the external evaluation criteria. The purpose of this paper is to show that the binary transformation is not necessary in the process of clustering categorical data since the second approach leads to at least comparably good clustering results as the first approach.
A COMPARATIVE ANALYSIS OF ECONOMIC EFFICIENCY OF MEDIUM-SIZED MANUFACTURING ENTERPRISES IN DISTRICTS OF WIELKOPOLSKA PROVINCE USING THE HYBRID APPROACH WITH METRIC AND INTERVAL-VALUED DATA
Authors: Dehnel Grażyna , Walesiak Marek
Published: September 2019

The article describes a hybrid approach to evaluating economic efficiency of medium-sized manufacturing enterprises (employing from 50 to 249 people) in districts of Wielkopolska province, using metric and interval-valued data. The hybrid approach combines multidimensional scaling with linear ordering. In the first step, multidimensional scaling is applied to obtain a visual representation of objects in a two-dimensional space. In the next step, a set of objects is ordered linearly based on the distance from the pattern (ideal) object. This approach provides new possibilities for interpreting linearly ordered results of a set of objects. Interval-valued variables characterise the objects of interests more accurately than metric data do. Metric data are atomic, i.e. an observation of each variable is expressed as a single real number. In contrast, an observation of each interval-valued variable is expressed as an interval. The analysis was based on data prepared in a two-stage process. First, a data set of observations was obtained for metric variables describing economic efficiency of medium-sized manufacturing enterprises. These unit-level data were aggregated at district level (LAU 1) and turned into two types of data: metric and interval-valued data. In the analysis of interval-valued data, two approaches are used: symbolic-to-classic, symbolic-to-symbolic. The article describes a comparative analysis of results of the assessment of economic efficiency based on metric and interval-valued data (the results of two approaches). The calculations were made with scripts prepared in the R environment.
ECONOMIC GROWTH AND ITS DETERMINANTS: A CROSS-COUNTRY EVIDENCE
Authors: Adepoju Adedayo A. , Ogundunmade Tayo P.
Published: September 2019

Empirical evidence from a panel of 126 countries, over the time period of 2010 to 2014, indicates that economic growth is dependent on various factors. This paper finds that government expenditure control, reduced inflation and increased trade openness are the factors that boost the economic growth of a country. Significant evidence is seen for government consumption, fiscal policy and trade openness. No significant relationship has been observed between exchange rate and economic growth, whereas unemployment influences output for African countries. The cross regional analysis of Asian, European, African, Caribbean, and American countries gives specific determinants for these regions. Economic growth is also analysed in developing, developed, least developed, Muslim and petroleum exporting and emerging countries.

The results of this study validate the dependence of economic growth on various factors. Fiscal balance has shown a consistent positive relationship with economic growth throughout the analyses. Fiscal balance and unemployment rate played their role in the growth of African countries. Inflation rates and increased openness were significant for some regions. Exchange rate did not return significant coefficients for any of the sub-regions. Government consumption, trade openness, policy interest rate and industrial production rate showed significant effect for different regions of the world.
ESTIMATION OF ENERGY INTENSITY IN INDIAN IRON AND STEEL SECTOR: A PANEL DATA ANALYSIS
Authors: Sharma Anukriti , Roy Hiranmoy , Dalei Narendra Nath
Published: September 2019

India is the world’s third largest consumer of primary energy, which includes fossil fuels like coal, oil, etc. The total primary energy consumption in India in 2015 was 107 Mtoe. India’s total final energy consumption was estimated at 527 Mtoe of which the industrial sectors consumed about 30% (185 Mtoe) in 2013. The Iron and Steel sector is one of the most energy-intensive industries, consuming about 25% of the total industrial energy consumption. The energy consumption in Indian Iron and Steel sector is on the declining trend. It declined from 10 GCal/tcs in 1990 to 6.9 GCal/tcs in 2010–11. On average, iron & steel plants spend about 20-40% of the total manufacturing cost to meet their energy demands. In fact, energy cost is considered as a major factor in pricing of the steel. Energy Conservation Act, 2001 (ECA), and the formulation of Bureau of Energy Efficiency are important initiatives taken up by government in order to reduce energy consumption by various sectors in the Indian economy. Another important initiative is launching of first of its kind market-based mechanism, Perform, Achieve and Trade (PAT) mechanism in 2010 particularly targeting the energy consumption by the industrial sector of the economy. Phase-I for PAT ran from 2012–015 including eight most energy-intensive sectors under Indian Industrial sector, with Iron and Steel sector being a prominent sector. The objective of this paper is to empirically estimate the energy intensity of Indian Iron and Steel sector, also accounting for the impact of ECA and PAT Phase-I in dummy variable form. The results indicate that the decline in energy consumption in this sector until 2011 can also be attributed to Energy Conservation Act implemented in the year 2001 along with other factors. This is empirically confirmed by our results that ECA has a significant impact on reduction of energy intensity of the steel firms. PAT does not seem to have a considerable impact on energy intensity alone but in the years where both PAT and ECA are prevalent, i.e. from 2012 to 2015, there seems to be a significant impact of around 0.050 reduction in energy intensity, as accounted by different models in this paper. There is one more observation from the empirical results that profit margin intensity was found to be negatively related to energy intensity implying more profitable firms invest more in energy efficiency.
EXTREME GRADIENT BOOSTING METHOD IN THE PREDICTION OF COMPANY BANKRUPTCY
Authors: Pawełek Barbara
Published: September 2019

Machine learning methods are increasingly being used to predict company bankruptcy. Comparative studies carried out on selected methods to determine their suitability for predicting company bankruptcy have demonstrated high levels of prediction accuracy for the extreme gradient boosting method in this area. This method is resistant to outliers and relieves the researcher from the burden of having to provide missing data. The aim of this study is to assess how the elimination of outliers from data sets affects the accuracy of the extreme gradient boosting method in predicting company bankruptcy. The added value of this study is demonstrated by the application of the extreme gradient boosting method in bankruptcy prediction based on data free from the outliers reported for companies which continue to operate as a going concern. The research was conducted using 64 financial ratios for the companies operating in the industrial processing sector in Poland. The research results indicate that it is possible to increase the detection rate for bankrupt companies by eliminating the outliers reported for companies which continue to operate as a going concern from data sets.

Authors: Dorugade Ashok V.
Published: September 2019

In this article, two-parameter estimators in linear model with multicollinearity are considered. An alternative efficient two-parameter estimator is proposed and its properties are examined. Furthermore, this was compared with the ordinary least squares (OLS) estimator and ordinary ridge regression (ORR) estimators. Also, using the mean squares error criterion the proposed estimator performs more efficiently than OLS estimator, ORR estimator and other reviewed two-parameter estimators. A numerical example and simulation study are finally conducted to illustrate the superiority of the proposed estimator.
Unconstrained and Constrained Predictive Control for the Multivariable Process with Non-minimum Phase
Authors: Zidane Zohra
Published: September 2019

Non-minimum phase Multi-input Multi-Ouput (MIMO) systems are known to be difficult to control. Model Predictive Control (MPC) algorithms are powerful control design methods widely applied to industrial processes. The handling of various input constraints in the MPC problem of ARIMAX non-minimum phase MIMO systems is considered. This approach is applied for control of industrial quadruple tanks. However, there is no easy way to solve the problem of constraints. The methods based on the quadratic programming (QP) technique are used to solve the constrained optimization problem. A comparative study of unconstrained and constrained control system behavior is given. Some illustrative simulation results for a considered system are presented and discussed. Encouraging results are obtained that motivate for further investigations.

VIOLAÇÕES A DIREITOS HUMANOS POR EMPRESAS TRANSNACIONAIS NA AMÉRICA LATINA: PERSPECTIVAS DE RESPONSABILIZAÇÃO
Authors: Olsen Ana Carolina Lopes , Pamplona Danielle Anne
Published: September 2019

Em virtude da constatação das graves violações de direitos humanos perpetradas por empresas transnacionais, e sua baixa responsividade, o presente estudo buscou identificar e discutir quais os fundamentos e mecanismos que o direito internacional dos direitos humanos oferece para promover a responsabilização civil desses atores privados, com foco na realidade latino-americana. A América Latina tem sido palco da atuação irresponsável de transnacionais em virtude de seu quadro social deficitário e da baixa institucionalidade na proteção dos direitos humanos. Pelo método hipotético-dedutivo, e mediante pesquisa bibliográfica, verificou-se fundamentos para deduzir a vinculação de empresas transnacionais a instrumentos internacionais de proteção aos direitos humanos, o que pode autorizar sua responsabilização perante os Estados em que praticam a violação, ou perante os Estados em que mantém o controle de sua atividade econômica e cadeia produtiva. Uma terceira hipótese, mais controversa, é a aplicação da jurisdição universal, cujo delineamento ainda carece de adesão dos Estados mas já dá sinais de viabilidade, na medida em que se associa a responsabilidade civil à penal internacional.
THE LAW OF PEOPLES: A UTOPIA REALISTA RAWLSIANA E A IDEIA DE JUSTIÇA SOCIAL ENTRE OS POVOS
Authors: Bagetti Zeifert Anna Paula
Published: September 2019

No presente artigo analisamos como o projeto de justiça social rawlsiano, pensado inicialmente para as sociedades nacionais, foi estendido para a Sociedade dos Povos na obra The Law of Peoples. Examinamos como John Rawls resgata e apresenta seus elementos essenciais na proposta de justiça entre os povos, sua preocupação em garantir estabilidade e o mínimo de justiça social no interior das sociedades que integram a Sociedade dos Povos. Ponderamos como seus objetivos se encontram interligados tanto na proposta de justiça política para o interior dos Estados, quanto na relação entre Estados, garantindo a legitimidade das sociedades a partir de uma estrutura básica e de instituições justas. Nesse contexto, nosso objetivo é demonstrar que ao pensar esse processo paralelo de justiça (nacional e internacional), e projetar uma segunda posição original, guia para seus elementos essenciais com vistas a promoção da justiça social entre os povos, Rawls também apresentou os limites da sua realistic utopia e os caminhos para a reconciliação do indivíduo com o mundo social ao qual pertence. O estudo foi desenvolvido com base no método de abordagem hipotético-dedutivo, utilizando uma base teórica presente na filosofia política contemporânea.
A CRIMINALIZAÇÃO E A MARGINALIZAÇÃO DOS MOVIMENTOS SOCIAIS NO BRASIL: O CASO DO COLETIVO FEMINISTA PAGU
Authors: Silva Thiago Henrique Costa , Ataídes Maria Clara Capel de
Published: September 2019

Este trabalho tem como objetivo discutir que, em um Estado democrático de direito, os movimentos sociais constituem instrumentos de resistência e reivindicação, quando enfrentam pautas que a sociedade civil ou outras entidades não teriam meios ou vontade política de abordar. Suas ações se constituem, a partir de seu diálogo com o Estado, em uma forma de ativismo público, e por isso legítima dentro do ordenamento jurídico vigente. Entretanto, o que pode ser depreendido da realidade brasileira é uma criminalização dessas formas de manifestação, de maneira a silenciar e tornar impossível a formulação desses ideais, que, na maioria dos casos, almejam mudanças e avanços políticos e jurídicos. Por fim, de forma a demonstrar a atuação do Estado frente aos movimentos sociais, por meio do método dedutivo, em abordagem qualitativa, analisa-se o caso do coletivo feminista Pagu e a tentativa de imputar a prática de vilipêndio a objetos religiosos, no Estado de Goiás, um exemplo da pauta antidemocrática, conservadora e hegemônica em que a sociedade e as formas políticas brasileira estão envolvidas.
PELA INTRODUÇÃO DE UMA EDUCAÇÃO AMBIENTAL ECOCÊNTRICA: VANTAGENS E DESAFIOS
Authors: Câmara Ana Stela
Published: September 2019

O presente trabalho tem por objetivo identificar vantagens e desafios à implementação de uma educação ambiental ecocêntrica no Brasil. A relevância da análise reside nas evidências de insuficiência dos parâmetros oferecidos pela tradição antropocêntrica dominante em lidar com a preservação ambiental, haja vista o constante aumento da degradação ambiental e da perda de biodiversidade. Acredita-se que a ênfase na perspectiva interrelacional levantada por uma educação ambiental de orientação ecocêntrica possa ser útil para subverter a lógica de exploração desregrada e de proteção fragmentada do meio ambiente e ampliar a percepção do caráter transfronteiriço e intertemporal dos fenômenos ambientais. A metodologia é analítica e descritiva, embasando-se em fontes bibliográficas e documentais. Conclui-se as vantagens de adoção do modelo ecocêntrico são promissoras, porém, que os desafios são muitos, pois a Política Nacional de Educação Ambiental ainda tem baixo nível de implementação em todas as suas esferas e suas ações normalmente não privilegiam a sensibilização para o funcionamento sistêmico do ambiente.

A FUNDAMENTAÇÃO DOS DIREITOS HUMANOS SEGUNDO ALEXY
Authors: Pracucho Davi Marcucci
Published: September 2019

Robert Alexy é conhecido, no Brasil, principalmente em função da sua teoria dos princípios, desenvolvida na interpretação dos direitos fundamentais. Todavia, na sua vasta obra, para além desse campo, o jusfilósofo alemão debruçou-se, outrossim, sobre os direitos humanos. Especificamente, sobre a sua fundamentação, objeto do presente artigo. Partindo da premissa de que, embora a efetivação dos direitos humanos seja crucial, dela não se dissocia o problema da fundamentação – vale dizer: existe uma complementaridade entre a fundamentação e a efetivação dos direitos humanos – procede-se, neste trabalho, a uma leitura da fundamentação dos direitos humanos em Alexy, antes a situando na sua teoria do direito e na filosofia do direito em geral, e objetivando, ao fim, evidenciar, também no pensamento do professor tedesco, aquela relação de complementariedade entre fundamentação e efetivação.

Published: September 2019

In this study, the equilibrium scour depth downstream of the weir (ds-a), the maximum scour depth downstream of the weir (ds-max), the equilibrium scour depth upstream of the weir (dus-a) and the maximum scour depth upstream of the weir (dus-max) were simulated around the submerged weirs using the self-adaptive extreme learning machine (SAELM) model. In other words, the SAELM was utilized for the simulation of the scour depths around submerged weirs for the first time. In addition, Monte Carlo simulations (MCSs) were used to increase the accuracy of the artificial intelligence model. The results of modeling were validated using k-fold cross validation. At first, all effective parameters on the scour depth were determined and five distinct SAELM models were defined. Then, the optimal activation function of the SAELM model was obtained. By analyzing the results of modeling, the best models were identified to estimate ds-a/ht, ds-max/ht, dus-a/ht, and dus-max/ht, and the ratio of the average inflow velocity to the critical velocity (U0/Uc) was determined as the most effective input parameter. In the following, the results of superior models were compared with the artificial neural network (ANN) and support vector machine (SVM). The results showed that SAELM models were more accurate. The uncertainty analysis was performed for these models, some of them were overestimated and others were underestimated. In addition, some equations were presented for equilibrium models for calculation of scour depth around the submerged weirs, which are used by environmental and hydraulic engineers without previous knowledge about the artificial intelligence models. Finally, a partial derivative sensitivity analysis (PDSA) was performed for all input parameters of the superior models.

New Media, Old Artistry: The Adaptation of Yorùbá Folktale Narrative Strategies in Video Films
Authors: Taiwo Adekemi Agnes
Published: September 2019

The argument of this study is that Yorùbá people continue to keep alive and sustain their society’s oral folkloric tradition and verbal art despite the changes undergone by Yorùbá folktales that have passed into written form and other (new) media. Verbal arts educate, reflect and promote culture, as well as, their well-known capacity to instil moral decency in a young audience. This paper explores the adaptation of Yorùbá folkloric form in film. The audience memory is reawakened through the conservation and propagation of folktale into drama form in the film, Ijàpá and Àjàntálá. Ìjàpá (tortoise) is well known for its trickish behaviour and nature while Àjàntálá is also known for his vicious behaviour. Their character was worn into human beings (artiste) to teach society moral lessons. These Yorùbá movies Ìjàpá and Àjàntálá were adapted from Yorùbá folktales to examine issues and themes that are germane to contemporary society. Ìjàpá was produced in 2011 while Àjàntálá was produced in 2015. The theory of intertextuality which is the way books, songs, films are linked or associated to one another is adopted for the research.
