Role of the Internet in Solving the Last Mile Problem in Medicine (Preprint)
Authors: Hesse Bradford William
Published: September 2019

UNSTRUCTURED

Internet-augmented medicine has a strong role to play in ensuring that all populations benefit equally from discoveries in the medical sciences. Yet, data from the Centers for Disease Control and Prevention collected from 1999 to 2014 suggested that during the first phase of internet diffusion, progress against mortality has stalled, and in some cases, receded in rural areas that are traditionally underserved by medical and broadband resources. This problem of failing to extend the benefits of extant medical knowledge equitably to all populations regardless of geography can be framed as the “last mile problem in health care.” In theory, the internet should help solve the last mile problem by making the best knowledge in the world available to everyone worldwide at a low cost and no delay. In practice, the antiquated supply chains of industrial age medicine have been slow to yield to the accelerative forces of evolving internet capacity. This failure is exacerbated by the expanding digital divide, preventing residents of isolated, geographically distant communities from taking full advantage of the digital health revolution. The result, according to the Federal Communications Commission’s (FCC’s) Connect2Health Task Force, is the unanticipated emergence of “double burden counties,” ie, counties for which the mortality burden is high while broadband access is low. The good news is that a convergence of trends in internet-enabled health care is putting medicine within striking distance of solving the last mile problem both in the United States and globally. Specific trends to monitor over the next 25 years include (1) using community-driven approaches to bridge the digital divide, (2) addressing structural disconnects in care through P4 Medicine, (3) meeting patients at “point-of-need,” (4) ensuring that no one is left behind through population management, and (5) self-correcting cybernetically through the learning health care system.

The pretransplant risk assessment for patients with ESKD who are undergoing evaluation for kidney transplant is complex and multifaceted. When considering cardiovascular disease in particular, many factors should be considered. Given the increasing incidence of kidney transplantation and the growing body of evidence addressing ESKD-specific cardiovascular risk profiles, there is an important need for a consolidated, evidence-based model that considers the unique cardiovascular challenges that these patients face. Cardiovascular physiology is altered in these patients by abrupt shifts in volume status, altered calcium-phosphate metabolism, high-output states (in the setting of arteriovenous fistulization), and adverse geometric and electrical remodeling, to name a few. Here, we present a contemporary review by addressing cardiomyopathy/heart failure, pulmonary hypertension, valvular dysfunction, and arrhythmia/sudden cardiac death within the ESKD population.
Barriers to Effective Prevocational education implementation in Jordanian Schools as Perceived by Teachers
Authors: Jawarneh Tariq Yousef
Published: September 2019

The main goal of this qualitative study was to explore perceptions and opinions of a group of in-service Prevocational Education (PVE) teachers to derive barriers to effective PVE implementation at the middle basic stage in Jordanian schools. The population and sample (n=35 of the study consisted of all teachers responsible for the delivery of PVE at the middle basic stage of the "North Mazar" educational directorate in the northern region in Jordan. The population and sample of the study were conveniently selected. The instrument used in this study was an interview schedule and technique used in analyzing data obtained from open-ended face-to-face interviews was that suggested by Merriam (2009) regarding qualitative data. Frequencies, percentages in addition to examples of sample quotes representing teachers' responses were provided. The results revealed that PVE lack attractiveness for pupils, parents, teachers, and principals and consequently they hold negative attitudes towards this practical provision. The results revealed four categories of barriers: (1), Barriers pertaining to perceptions and attitudes (2) barriers pertaining to economic factors, (3) barriers pertaining to administrative factors, (4) Barriers pertaining to human factors. Discussions of such barriers were provided, and concluding reflections and recommendations were presented.

Customer Commitment as a Mediating Variable between Corporate Brand Image and Customer Loyalty
Authors: Tu Yu-Te , . Yu-Yi Chang
Published: September 2019

Research has shown that corporate image is an important determinant of customer loyalty. Having a positive corporate brand image helps companies achieve performance goals, such as higher sales, whereas having a poor brand image can be disastrous because it can cause companies to lose customers. A strong brand with high equity will have a large number of committed customers, many of whom will have frequent and ongoing interaction and communication with the company owning the brand. Customer commitment to a brand stems from trust in the brand, shared values with the company owning the brand, and a belief that it would be difficult to find other brands that could provide same value. Customer loyalty also encourages companies to cooperate with their business partners to preserve their investment in the business relationship. Committed customers have a more positive impression of their relationship with the company and indicate strong intentions to remain in the relationship. The researchers conducted a survey among respondents from the automobile sector in Taiwan, and obtained 170 usable responses. The researchers designed the questionnaires to analyze normality, convergent, and discriminant validities by using the structural equation model of PASW 18 and AMOS 18.0. The research found that commitment is a partial mediator between corporate brand image and customer loyalty. Future studies might measure other dimensions to test their mediating effect on customer loyalty, and these studies might use different designs to examine the mediator effect posited by various theories, such as trust added, to explore other determinants of loyalty. Such research can inform decisions made to increase and maintain long-term customer satisfaction.

Authors: Morrison Sarah , . Samuel Sundong
Published: September 2019

The study explored the various causes of conflicts in organizations. The objectives of the study was to find out the nature, types and factors that lead to staff related conflicts in organizations especially tertiary educational institutions. To achieve the objectives, researchers employed the case study approach using Takoradi Polytechnic as the case study. It also involved the use of interview and questionnaire as the data collection instruments for the study. Researchers used the purposive and simple random sampling techniques to select the respondents. A sample size of 276 out of 736 of the population was selected for the study. This constitutes (36%) of the population. The sample was made up of 109 junior staff, 96 senior staff and 71 senior members. These three groups of staff from different departments were randomly and purposively invited to participate in the study. The study would be of immense benefit to management of institutions especially educational institutions since it would inform them of possible conflict that could arise. It would also inform policy formulation and staff training and development programs. It was discovered after the study that there were various conflicts in the organization which could be grouped into intra-personal, interpersonal and inter-group conflicts. These were as a result of the competing for limited resources, power struggle, differences in behavior among others. It recommends the education of staff through workshops and seminars on the differences that leads to conflicts, provision of resources and infrastructure that could mitigate the competition of resources among others.
An inexpensive anemometer using Arduino board
Authors: Avallone Elson , Mioralli Paulo , Natividade Pablo , Palota Paulo , da Costa , Antonio Jonas , Aparecido Verdério
Published: September 2019

In all studies involving wind speed, such as meteorology, wind turbines and
agriculture accurate speed information for decision making is required.
There are several types of anemometers, with medium and high costs, such as
cup, hot wire and pitot tubes, the hot wire being more sensitive and
expensive than others. The device developed in this work is the cup
anemometer, that is easy to build. The great advantage of this device is the
low cost, with an approximate value of US$ 50.00, using simple materials
that are easy to find in commercial stores. The Reed Switch sensor is also
another advantage as it does not require a sophisticated programming, as
well as the open platform Arduino. The use of theoretical aerodynamic drag
coefficients and the presented calculations resulted in values very close to
a commercial anemometer. The coefficient of determination between the cup
Anemometer and the standard sensor of Meteorological Research Institute
IPMet/Brazil is R2=0.9999, indicating strong correlation between the
instruments. As the reference anemometer (IPMet) has high embedded
technology and the prototype is low cost, we conclude that the project has
an attractive cost benefit for possible development and production, reaching
the objective of this work.

The power sector is about to undergo a major disruptive transformation. In
this paper, we have discussed the best possible energy solution for
addressing the challenges of climate change and eradication of energy
poverty. This paper focusses on the decentralized power generation, storage
and distribution through photovoltaics and lithium batteries. It encompasses
the need for local direct current (DC) power through the factors driving
this change. The importance of local DC power in the transportation sector
is also established. Finally, we conclude with data bolstering our argument
towards the paradigm shift in the power network.
Is the Pollution Haven Hypothesis (PHH) valid for Turkey?
Authors: Terzi Harun , Pata Ugur
Published: September 2019

The relationship between FDI inflows and carbon dioxide (CO2) emissions is still one of the most important topics among both environmentalists and economists. In this study, the Toda-Yamamoto augmented Granger causality method is applied to analyze the relationship between FDI inflows and CO2 emissions by employing annual data from 1974 to 2011 to determine whether the pollution haven hypothesis is valid in Turkey. The results of the causality test indicated that FDI inflows and CO2 emissions have a short-run univariate causal relationship, with positive causality moving from CO2 emissions to FDI inflows. One direction effect of CO2 emissions on FDI inflows supports the pollution haven hypothesis in Turkey.

A formação do professor na modalidade a distância: (des)construindo metanarrativas e metáforas
Authors: Preti Oreste
Published: September 2019

A discussão sobre a formação do professor ganha novos contornos, hoje, ao ser associada à modalidade de educação a distância. Por quê? Inicialmente, nos propomos analisar práticas discursivas hegemônicas de mudanças na ação pedagógica e de (re)significação da mesma em relação à formação do professor, ao gerenciamento da escola e ao uso das novas tecnologias. Neste movimento inserem-se as propostas de formação e treinamento a distância, em expansão acelerada a partir do final da década de 90. O que nos propomos, num segundo momento, é analisar, no percurso da experiência do Núcleo de Educação Aberta e a Distância (Nead) da Universidade Federal de Mato Grosso (UFMT), na formação de professores, algumas "práticas" consideradas como explicativas da sua consolidação, no sentido de (res)significarmos discursos sobre a formação do professor.

Palavras-chave: fomação de professores; educação a distância.

Abstract

The discussion about teachers' training has gained new outlines nowadays, when being associated with distance learning. Why is it so? Initially, we intend to analyze discursive hegemonic practices, which produce changes in pedagogical actions and of (re)signification of it in relation to teacher's training, to the school's management and to the use of new technologies. In this movement, it was included the formation and distance training propositions, which have grown extensively since the end of 90's. What we intend in a second stage is to analyze, on the basis of the experiment of the Open and Distance Education Group of the Federal University of Mato Grosso in teachers' training, some "practices" considered as explanatory of its consolidation, in the sense of (re)signifying discourses about teachers' training.

O “problema” da “cola” sob a ótica das representações
Authors: Rangel Mary
Published: September 2019

A questão da "cola" é polêmica e controversa, seja do ponto de vista didático e de avaliação, seja na perspectiva de valores. Por isso, a "cola" se configura como um problema significativo e instigante de pesquisa. Assim, problematizar a "cola" é repensá-la de modo crítico e fundamentado, que possibilite perceber e analisar os diversos ângulos de sua origem e circunstâncias. Nessa perspectiva, este estudo recorre à teoria de representação social para discutir imagens e conceitos, práticas, instrumentos e, também, alternativas para o problema, com especial atenção às inter-relações entre seus motivos escolares e psicossociais.

Palavras-chave: representação social; cola; ensino; pesquisa.

Abstract

"Cheating on tests" is one of the problems that persist at school scene. Like any everyday problem, it has to be seen not only as a point of difficulty or an obstacle, which leads to the immobilization or frustration, but as a question to be surveyed. The motivation to that survey is based on the argument and proposal of the teacher-researcher and the bond, which is established between teaching and research. Thus, turning "cheating on tests" into a problem is to rethink it on a critical and based way, which enables to perceive and analyze the several sides of its origin and circumstances. In that perspective, that survey goes over to the social representation theory to discuss images, concepts and practices as well as alternatives of that "problem", giving attention to the interrelation between school and psychosocial reasons.

Keywords: social representation; "cheating on tests"; teaching; research.
Media Exposure, Utilization, Satisfaction, and Need for Service Business Information of Consumers in the Digital Economy Era
Authors: Tansiri Ekachat , Devahastin Sirivimol
Published: September 2019

The objectives of this research were: 1) to study the media exposure, utilization, satisfaction, and need for service business information of consumers in the digital economy era, 2) to examine the relationships between the media exposure, utilization, and satisfaction with service business information of consumers in the digital economy era, and 3) to present the problems, obstacles, and suggestions regarding digital media communication of consumers in the digital economy era. A quantitative survey research method was applied. The sample consisted of 400 consumers in Bangkok, ages 37-50 years, who were exposed to digital media on tourism service businesses, such as websites, Facebook, YouTube, Instagram, blogs, and Line. The research tool was a questionnaire, and the statistics used in data analysis were percentage, mean, and standard deviation. Hypothesis testing was done by using the Pearson product-moment correlation coefficient. The results showed that most respondents were female, ages 37-40 years, worked in private companies, and had an average monthly income of 10,001-20,000 baht. The majority of respondents were exposed to YouTube videos and Facebook pages on restaurant service. Service business information was used to satisfy their personal interests. Regarding satisfaction with business information, YouTube was found to be the most interesting form of digital media, whereas the other forms of digital media needed the right content. The observed problem was outdated and unreliable information. The hypothesis testing showed that media exposure behavior was significantly correlated (at 0.05 level) with the media utilization and satisfaction with service business information of customers in the digital economy era. Based on the results, it is suggested that digital media be used in new media convergence and modern marketing for better control of the accuracy and reliability of data in order to ensure that the creation and development of digital media in the service sector is consistent with the digital economic policy of the national government.
Is Human Capital in Higher Education Ready for Thailand 4.0: A Case Study of SSRUIC Students, Nakorn Pathom Education Center
Authors: Kankaew Kannapat
Published: September 2019

Presently, the Thai government has implemented its so-called Thailand 4.0 policy to move away from the middle-income trap to a value-based economy. Howbeit, human capital development is a crucial part for driving the policy’s success. Hence, this study aims to assess the perception of Thailand 4.0, the factors affecting learning, and the effectiveness of teaching. A mixed method research approach was applied; this comprised researcher administered structured observation in the classroom and in-depth interviews. The AMOS was manipulated for structural equation modeling to test the relationship between exogenous and endogenous variables. The result revealed that 63 per cent of the respondents understand the policy at a fair level. Surprisingly, only 2 per cent were shown to have the highest degree of understanding the policy. Whilst, the top three factors affecting learning are enhancement from family, motives to learn, and passion to be successful in future careers. Whereas, the most preferable methods of learning are lecture, simulation and role-play. In summary, there are myriad methods for educating as well as multiple contexts affecting learning. In particular, the motives, values and culture of learners. As a result, teachers should motivate student more and prepare the teaching approaches that fit the specific learners of within each classroom.
Beyond the Politics of Inclusion: The Policy Environment and the Fate of Children with Disability in the Ghanaian Educational System
Authors: Mantey Efua Esaaba
Published: September 2019

The 1992 constitution of Ghana and other national legislative instruments guarantee and promote free compulsory universal basic education for all Ghanaian children irrespective of their background. This has been the practice for many years. Even though these policies have chalked some successes, especially regarding school attendance and gender parity, there still remains some level of uncertainty as to whether all Ghanaian children, especially those with disabilities, benefit from these policies. Using secondary information available, the paper provides an overview of the existing legislative instruments that seek to promote the adoption of inclusive education policy in Ghana. Evidence from the literature reveals that there are restrictions within the current policy provisions which make inclusive education not possible for children living with disabilities. The paper concludes and recommends that there should be some modifications or new developments of inclusive education to enable the system to accommodate the diverse educational needs of children with disabilities.
Evaluation of the chemical composition and bioactivity of essential oils from Cinnamomum camphora (L.) J.Presl. (Lauraceae), Piper nigrum L. (Piperaceae) and Stemona japonica (Miq.) (Stemonaceae) against Oryzaephilus surinamensis (Linnaeus, 1758) (Coleoptera: Silvanidae)
Authors: Wagan Tufail Ahmed , Li Xiang , Hua Hongxia , Cai Wanlun
Published: September 2019

Oryzaephilus surinamensis is a serious insect pest of many stored products. Repellency and fumigation tests were performed to manage it. Essential oils (EO) from three plants – Cinnamomum camphora, Piper nigrum and Stemona japonica – were tested on Oryzaephilus surinamensis in the laboratory. Repellency was tested on filter paper in Petri dishes at a concentration of 31.4 μg/cm2, and 20 adults (10 days old) were observed for repellency behaviour 12, 24, 48 and 96 hours after the bioassay without any food. Cinnamomum camphora EO was the strongest repellent (83.75 ± 1.83%), followed by the Piper nigrum and Stemona japonica EOs. The eggs were obtained by maintaining 20 individuals (males and females) for 24 h in a 100 mL glass jar containing 5 g of diet feed. To evaluate the effect of EO on the development of larvae and adults, a filter paper disc impregnated with 0.1 mL of EO was placed on the inner side of the lid of the jar containing the eggs and diet feed. After 40 days, the number of adults and larvae in the jar was counted. All three EOs exhibited bioactivity against the development of larvae and adults. A relatively low number of larvae and adults was recorded in Cinnamomum camphora, followed by Stemona japonica and Piper nigrum. Gas chromatography/mass spectrometry was used to identify the major compounds in the EOs. Further studies are recommended to evaluate their bioactivity against different insect pests in stored seeds.

Published: September 2019

Distributional data for 10 species of Peltidae, Lophocateridae, Trogossitidae and Thymalidae recorded from Poland are summarised, and numerous unpublished records are reported. Data on feeding and habitat preferences are analysed. Calitys scabra and Temnoscheila caerulea are probably extinct in Poland. Grynocharis oblonga, Nemozoma elongatum and Tenebroides mauritanicus are relatively common in Poland. Nemozoma caucasicum is currently spreading within Europe and several new records in Poland are reported. Peltis ferruginea, P. grossa, and Thymalus limbatus are restricted to natural forests in Poland, where they are sometimes abundant. We suggest adding Peltis ferruginea and Thymalus limbatus to the Polish Red List of Animals. The opinion that Grynocharis oblonga and Tenebroides mauritanicus are relicts of natural forests does not seem justified.
Idiopathic pulmonary fibrosis in patients with early-stage non-small-cell lung cancer after surgical resection
Authors: Nezka Hribernik , Igor Pozek , Izidor Kern
Published: September 2019

Background

The outcomes of patients with both lung cancer and idiopathic pulmonary fibrosis (IPF) are unfavorable. Therapeutic interventions for lung cancer such as surgery can cause acute exacerbation of IPF (aeIPF). This study aimed to assess the frequency of IPF in a group of patients with early-stage non-small-cell lung cancer (NSCLC) and to report clinical characteristics and outcomes of this cohort of patients.

Patients and methods

This observational cohort retrospective study analyzed 641 pathological records of patients after surgical resection of early-stage non-small-cell lung cancer (NSCLC) at University Clinic Golnik from May 2010 to April 2017. Pathological records of NSCLC with coexisting IPF were reviewed. CT scans and biopsy specimens for this group of patients were analyzed by a thoracic radiologist and pathologist, independently. We searched radiological and pathological features of usual interstitial pneumonia (UIP) pattern in this group of patients. We report the clinical characteristics and outcome of this cohort of patients.

Results

Out of 641 patients with early-stage NSCLC, only 13 (2.0%) had histologically and radiologically proven coexisting UIP/IPF. Squamous cell carcinoma was the most common type of lung cancer (7/13 patients). The majority of tumors were small size (all being pT1 or pT2), stage I–II (11/13 patients), located in the lower lung lobes (11/13 patients). Almost all patients were current or ex-smokers (11/13 patients). There were two pathologically confirmed fatal cases (15.4%) due to aeIPF in the first two months after radical treatment, one after adjuvant radiotherapy and the other after surgery. Out of 13 patients, one patient had a lung cancer relapse.

Conclusions

Frequency of UIP/IPF in surgically treated early stage NSCLC is rather low. Our observational study shows that radical treatment of lung cancer can cause aeIPF with dismal outcome in this group of patients. The standard of care in these mostly elderly patients still remains unresolved.
Relationship between sex hormones levels and 18F-FDG uptake by the ovaries in premenopausal woman
Authors: Kim Tae Hee , Kim Mi Ran , Jung Yongsik , An Young-Sil
Published: September 2019

Background

The study was conducted to evaluate the effect of sex hormones on F-18 fluorodeoxyglucose (18F-FDG) uptake by normal ovaries.

Patients and methods

A total of 197 premenopausal women were included in this study. Based on 18F-FDG positron emission tomography/computed tomography (PET/CT) images obtained from these subjects, the association of ovarian 18F-FDG uptake with levels of sex hormones, including estradiol, progesterone, testosterone, follicle-stimulating hormone, and luteinizing hormone was investigated. We also analysed the relationship between the menstrual cycle and ovarian 18F-FDG uptake.

Results

The highest ovarian 18F-FDG uptake occurred at 2 weeks after the onset of menstruation (median maximum standardized uptake value [SUVmax] = 3.40, median mean SUV [SUVmean] = 2.20), and the lowest ovarian 18F-FDG uptake was observed during the first week of the menstrual cycle (median SUVmax = 1.60, median SUVmean = 1.20). Ovarian 18F-FDG uptake was weakly positively correlated with progesterone levels (rho = 0.28, p < 0.001 for SUVmax, rho = 0.30, p < 0.001 for SUVmean), and this pattern was consistently observed in subjects in the follicular-phase group (rho = 0.29, p = 0.003 for both SUVmax and SUVmean) but not in subjects in the luteal-phase group.

Conclusions

Based on PET images, ovarian glucose metabolism in premenopausal women tended to increase slightly with increasing progesterone concentration.
Multigene expression signatures in early hormone receptor positive HER 2 negative breast cancer
Authors: Ovcaricek Tanja , Takac Iztok , Matos Erika
Published: September 2019

Background

The standard treatment of hormone receptor positive, HER2 negative early breast cancer (BC) is surgery followed by adjuvant systemic therapy either with endocrine therapy alone or with the addition of chemotherapy followed by endocrine therapy. Adjuvant systemic therapy reduces the risk of recurrence and death from BC. Whether an individual patient will benefit from adjuvant chemotherapy is an important clinical decision. Decisions that rely solely on clinical-pathological factors can often lead to overtreatment. Multigene signatures represent an important progress in optimal selection of high risk patients that might benefit from the addition of chemotherapy to adjuvant endocrine therapy.

Conclusions

Several signatures are already commercially available and also accepted by international guidelines. Oncotype DX and MammaPrint have been most extensively validated and supported by level IA evidence.
Dosimetric study for spine stereotactic body radiation therapy: magnetic resonance guided linear accelerator versus volumetric modulated arc therapy
Authors: Yadav Poonam , Musunuru Hima B. , Witt Jacob S. , Bassetti Michael , Bayouth John , Baschnagel Andrew M.
Published: September 2019

Background

Stereotactic body radiation therapy (SBRT) given in 1-5 fractions is an effective treatment for vertebral metastases. Real-time magnetic resonance-guided radiotherapy (MRgRT) improves soft tissue contrast, which translates into accurate delivery of spine SBRT. Here we report on clinical implementation of MRgRT for spine SBRT, the quality of MRgRT plans compared to TrueBeam based volumetric modulated arc therapy (VMAT) plans in the treatment of spine metastases and benefits of MRgRT MR scan.

Patients and methods

Ten metastatic lesions were included in this study for plan comparison. Lesions were spread across thoracic spine and lumbosacral spine. Three fraction spine SBRT plans: 27Gy to planning target volume (PTV) and 30Gy to gross tumor volume (GTV) were generated on the ViewRay MRIdian Linac system and compared to TrueBeamTM STx based VMAT plans. Plans were compared using metrics such as minimum dose, maximum dose, mean dose, ratio of the dose to 50% of the volume (R50), conformity index, homogeneity index and dose to the spinal cord.

Results

MRIdian plans achieved equivalent target coverage and spinal cord dose compared to VMAT plans. The maximum and minimum PTV doses and homogeneity index were equivalent for both planning systems. R50 was lower for MRIdian plans compared to VMAT plans, indicating a lower spread of intermediate doses with MRIdian system (5.16 vs. 6.11, p = 0.03).

Conclusions

MRgRT can deliver high-quality spine SBRT plans comparable to TrueBeam volumetric modulated arc therapy (VMAT) plans.

Özellikle maden sahalarının geniş alanlar kaplaması, ölçümlerinin uzun zaman alması ve maliyetli olması, İHA’lar ile birlikte fotogrametrik görsel işleme yazılılarının kullanımını ihtiyaç haline getirmektedir. Hazırlanan çalışma, örnek bir maden sahasında gerçekleşen hacim, alan ve kabarma faktörü gibi, özellikle açık işletme madenciliğinde planlama ve hesaplamalarda kullanılan bazı verilerin, İHA kullanımı ile hızlı ve güvenilir bir biçimde eldesini konu almaktadır. Çalışma sonucunda, ele alınan sahada klasik metotlarla yapılan hesaplamaları ile İHA’lar ile elde edilen verilerin, uyumlu ve birbirlerine oldukça yakın değerler verdiği saptanmış ve sonuçlar yorumlanmıştır.

Oblique zooplankton tows were carried out in the Gerlache Strait from 17 to 22 January 2015 as part of the first Colombian oceanographic expedition to the Antarctic continent, to document the composition and structure of the epipelagic copepod assemblage, taking into account variations at a small spatial scale. The epipelagic environment of the Gerlache Strait was divided into two oceanographic regions during sampling: a stratified northern region and a homogeneous southern region. The epipelagic copepod assemblage comprised 17 species belonging to four orders and 13 families. Adult copepods as well as developmental stages ranging from copepodite II (C2) to copepodite V (C5) from eight different species were recorded in the study area. The dominant species by number was Oithona similis, followed by O. frigida, Ctenocalanus citer, Drescheriella glacialis, and Calanoides acutus. There were significant differences between the epipelagic copepod assemblages present in the northern and southern regions of the Gerlache Strait (Anosim, p = 0.01), with a dissimilarity percentage of 52%. Moreover, Aetideus armatus is reported for the first time in the western sector of the Antarctic Peninsula. The oceanographic conditions and the geomorphological characteristics of the study area modulated the surface circulation pattern, as well as the structure and composition of the primary producers during the study period, determining the spatial variation of the abundance and composition of the epipelagic copepod assemblage in the Gerlache Strait during the 2015 Austral summer.
Pressupostos materialistas em dialética do concreto : para pensar cidades e patrimonialização
Authors: Costa Everaldo Batista da , Araújo Gilvan Charles Cerqueira de , Oliveira Rafael Fabrício de , Rúbio Rúbia De Paula , Freire Janaína Mourão
Published: September 2019

A publicação do presente trabalho dá ênfase à importância do debate teórico-metodológico e epistemológico no contexto geográfico, em um momento de crise paradigmática enaltecedora de um pragmatismo tacanho e faceiro que acomete as ciências em geral. No âmbito geográfico, abundam em revistas nacionais e internacionais publicações destinadas a revelar o que se diz resultados de pesquisas comprometidas com o desvendamento das contradições socioespaciais. Entende-se que muito do que é produzido, sobretudo em teses e dissertações defendidas, depois publicadas, carecem de verdadeiro amadurecimento ou aprofundamento teórico e epistemológico. A crise se dá não diretamente pelo novo tempo da produção acadêmica, o qual se redimensionou de fato, no decorrer das últimas três décadas, dadas as facilidades informacionais de circulação e acesso aos acervos, às fontes e para a elaboração concreta do trabalho; esta crise advém, sim, de um descompromisso intelectivo generalizado com a produção do conhecimento original; crise fomentada pela ideologia numérica ou formal das publicações.
Políticas Públicas no Turismo sob a ótica da Complexidade: reflexões sobre interações entre aspectos públicos e privados
Authors: Vilela Graziele Junia Pereira , Costa Helena Araújo
Published: September 2019

O presente artigo ensaístico tem como tema a complexidade no turismo e em suas políticas públicas, apresentando uma reflexão acerca do modo como elas interagem, em nível municipal, com outras duas variáveis do universo privado: capacidade empresarial dos destinos turísticos e o desempenho econômico dos pequenos negócios da cadeia produtiva do turismo. Nesse sentido, a construção teórica propõe uma reflexão sobre o turismo como fenômeno complexo, a evolução de sua representação enquanto sistema aberto e possíveis interações entre seus componentes. O que permitiu elaborar um mapa mental no qual se evidencia que as políticas públicas partem de um contexto maior, que envolve as conjunturas políticas, econômicas e sociais dos destinos turísticos. Constata-se então uma rede de interações mútuas entre as variáveis analisadas, próprias da complexidade, em que as políticas públicas não apenas influenciam, mas também sofrem influências de características privadas do turismo que ocorre em dado território.

Authors: Passos Rachel Gouveia , Moreira Tales Willyan Fornazier
Published: September 2019

O presente artigo é oriundo das inquietações dos/as autores/as a despeito da interlocução, bem como do debate entre a saúde mental e a questão racial. Objetiva aproximar e relacionar as afinidades existentes entre a luta antimanicomial e a luta antirracista. Aborda sobre a composição do campo da saúde mental e da atenção psicossocial, enfatizando os projetos societários que estão em disputa na Reforma Psiquiátrica e na Luta Antimanicomial, problematizando os caminhos percorridos até o momento. Em seguida estabelece a discussão acerca das bases da formação sócio-histórica brasileira, a qual está assentada no patriarcado, no colonialismo e na ideologia racista, pontuando os resquícios escravocratas presentes na contemporaneidade, contextualizando a situação de segregação/subalternização/violência vivenciada pela população negra até os dias atuais, evidenciando os seus rebatimentos no campo da saúde mental. Finda com reflexões que convocam à necessidade imperativa de radicalização da luta política que vislumbre o horizonte estratégico de outra ordem social.
Uma esquerda marxista fora do lugar:
Authors: Farias Marcio
Published: September 2019

Pretendo neste ensaio apresentar alguns pontos para discussão sobre o impasse que assola a esquerda marxista tradicional brasileira, suas novas formas e a esquerda pós-moderna diante da questão racial. Para tanto, resgato o debate do marxismo como teoria social que não só pode como já nos legou um amplo cabedal teórico sobre o tema, inclusive entre os intelectuais de esquerda no Brasil. No segundo momento, retomo as teses da recepção do marxismo no país, para, porfim, discutir a base teórica da esquerda contemporânea e as dificuldades e desafios para o marxismo brasileiro. Como considerações finais, assinalo a necessidade de um acerto de contas da teoria social marxista com o Brasil, naquilo que se vem produzindo enquanto ciência nas mais variadas áreas de conhecimento e que colocam em questão premissas retomadas e defendidas. Assim, o problema não é de ordem epistemológica e sim de apreensão do dado objeto de análise.

Cristalización y Plastificación de Margarina Industrial para Panificación
Authors: Salas Sotaminga Yolanda , Tapia Ivan , Garzón Marcelo
Published: September 2019

La margarina es una de las materias primas utilizadas en la elaboración del pan, producto de consumo diario para alrededor de 13 millones de habitantes del Ecuador. Tomando en cuenta que la calidad del pan depende de la margarina, y ésta a su vez de las estructuras cristalinas ß’ que proporcionan a la margarina consistencia homogénea, brillo y color, se estudió la influencia de los parámetros de producción estándar en las características de la margarina. Once condiciones de producción con cuatro variables: caudal, temperatura de emulsión, temperatura de enfriamiento y velocidad de cristalización, se investigaron y las diferencias estructurales se analizaron utilizando microscopia de luz polarizada, análisis reológico, análisis calorimétrico diferencial y evaluaciónsensorial. Los parámetros óptimos de producción que influyen directamente en la formación de estructuras cristalinas ß’, fueron: temperatura de enfriamiento de 14°C a 16°C, caudal de emulsión de 1590 Kg/h a 1690 Kg/h, velocidad de cristalización de 220 a 240 rpm. La temperatura de emulsión fue un parámetro que no influyó en la formación de los cristales.
Estudio Comparativo de los Parámetros Cinéticos del Sistema Fe(CN)6 3-/4- en Carbón Vítreo y Diamante Dopado con Boro, Mediante Voltamperometría de Corriente Muestreada y Disco Rotatorio
Authors: Espinoza Montero Patricio J. , Fontana Uribe Bernando A
Published: September 2019

Se llevó a cabo un estudio comparativo de los parámetros cinéticos tanto para la oxidación como para la reducción del sistema redox Fe(CN)6 3-/4- en un electrodo de disco rotatorio de diamante dopado con boro (RDE-BDD, por siglas en inglés) y un electrodo de disco rotatorio de carbón vítreo (RDE-VC, por sus siglas en inglés) mediante voltamperometría lineal y voltamperometría de corriente muestreada, y se compararon ambas técnicas.

Los resultados encontrados muestran que las dos técnicas son complementarias para sistemas cuasi-reversibles. Además, los resultados obtenidos sobre un electrodo de BDD se compararon con datos informados en la literatura reportados mediante voltamperometría cíclica en régimen estacionario. Se demostró la importancia del control de transferencia de masa durante los experimentos de estudio cinético del sistema en estudio.
