TAA Properly Defined
Authors: Brown Robert A.
Published: June 2018

Tactical Asset Allocation (TAA) has generally been misspecified, oversold, and subsequently underdelivered. Nevertheless, TAA offers a series of highly attractive investment attributes when adviser/client expectations are properly set and the strategy is appropriately positioned as a portion of a comprehensive investor solution. This article’s objective is three-fold. First, to identify the attractive investment attributes of TAA relative to passive buy & hold. Second, to quantify or parameterize these relative advantages so that users can better assess the relevance of TAA for their own specific needs. Third, this article’s last objective is to describe the give-ups or tradeoffs associated with TAA, so that it can be properly understood, communicated, and therefore applied to the correct portion of an investor’s aggregate portfolio.
Can Capital Structure Affect the Financial Performance of Banks in Turkey?
Authors: Tuncay Merve
Published: June 2018

The aim of this study is to investigate the determinants of banks’ financial performance in terms of the capital structure. Annual financial statements of 11 banks traded in Borsa Istanbul are employed for the period of 2006-2016. Return on assets, return on equity and earnings per share are chosen for financial performance measures. The independent variables related to the capital structure are capital adequacy, equity-to-asset, and financial leverage ratios. In addition, macroeconomic variables and bank-specific variables are also considered as control variables for the analysis. The data are analyzed by the panel data regression analysis as it provides more informative finding and less multicollinearity among variables than time series and cross-sectional analyzes.

The Hausman test results indicate that the random effects model is appropriate for the whole dependent variables. According to the findings; while equity-to-asset ratio affects return on assets positively, amongst the control variables specific to firms, firm size, asset quality and asset growth variables have significant effects on return on assets. It is found no significant effect of independent variables on return on equity, however, it is seen that asset quality has a negative and significant effect. Inflation and interest rates have a significant effect on both variables. Finally, it is seen that equity-to-asset ratio has a positive and significant effect on earnings per share. Only the effect of asset quality on earnings per share is found to be significant among the control variables. Findings of the study are consistent with the previous studies. In addition, the M&M views are not supported by the findings related to return on assets and earnings per share but the return on equity.
Evolution Framework of the Classical Economics of Urbanization
Authors: Wu Yin
Published: June 2018

The urbanization is a process, but also a period of history; in theory, the classical economists had paid attention to the importance of urbanization on economic growth, also to examine those confusion in the growth and development of urbanization which facing the "dust, mud, swamp, jungle". What kind of urbanization need we pursuit? Petty, Smith, Marx, Marshall, Lewis, Yang Xiaokai and Harvey respectively researched from the different perspective of the development of urbanization in their view, this paper will be integrated into urbanization of the classical school of Architecture, and in time for the " longitude", the division of labor is the "latitude", depicts the main theory clues of urbanization by classical field which these scholars have analyzed. Overall, the urbanization problems encountered in the world today, which the classical economists have more or less analyzed or even if forecast and put forward appropriate solutions. It is very different from the study on the urbanization in the Neo-classical school who focus on technical analysis, the classical school of economists pay more attention to the analysis of the history of urbanization, class analysis and case analysis, they are very good at deep into the various contradictions and problems of urbanization development in the countries, to explore the cause, process and development trend of urbanization. They are extremely important wealth for policy makers and scholars who will research later on urbanization. It need timely summary of precipitation and learn from the discussion of the essence.
Implications of Tax Havens on Government Revenue
Authors: Karikari Nana Kwasi
Published: June 2018

The contribution of government expenditure to the level of economic growth cannot be underestimated. Unfortunately, resources for the governmental expenditure, though limited, find their way out of the coffers. This paper tries to elaborate on the adverse effect of the existence of tax havens on government expenditure that seeks to promote economic growth in developing countries. Literature indicates that high tax rates are a fundamental reason for the proliferation of government developmental funds-taxes, being syphoned to tax havens. Corrupt officials in government are also deemed to aid the intended government tax in reaching tax havens. In the end, international integration of tax bodies within governments and economies may lead to the strengthening of tax laws and downward review of tax rates can make tax obligations conducive and compelling, for economic growth.
The Dynamic Relationship between Oil Prices and Exchange Rates
Authors: Sakaki Hamid
Published: June 2018

Using daily data of oil prices and exchange rates of 14 countries for the period January 1999 to November 2014, this study examines the dynamic correlation between oil prices and exchange rates by DCC-GARCH model. The results show the significant negative correlation between oil prices and exchange rates over the period. These results imply that the increase of oil price is coinciding with US dollar depreciation and vice versa.  This correlation strengthens in negative direction during financial crisis period, while it shifts to an upward trend after financial crisis period.
Co-integration Between Globalisation and Economic Growth
Authors: Ferreira Cândida
Published: June 2018

This paper analyses the co-integration relationship between globalisation and economic
growth of 27 more or less developed countries across almost all Continents for the time period
1970–2013. Globalisation is proxied by the overall globalisation index and the sub-indices
representing economic globalisation, social globalisation and political globalisation, all
provided by the Swiss Economic Institute. Economic growth is measured through the natural
logarithm of the real Gross Domestic Product, sourced from the World Development
Indicators which are provided by the World Bank. Co-integration is tested with quantile cointegration regressions. The results obtained clearly confirm the existence of non-linear cointegration relationships between the considered globalisation indices and the real economic
growth.
The Importance of Scientific Research: the Case of Insurance for Climate Change
Authors: Porrini Donatella
Published: June 2018

Climate change is likely to cause extreme weather events in the world with the consequence of an increased number of natural catastrophes. The expected damages pose serious challenges to governments in terms of policy choice and a crucial point is to define the role can be played by insurance sector, particularly as a tool to reduce potential damage, as well as to stimulate mitigation. Scientific research and good knowledge of risk are necessary in guiding policy decisions to manage the risks deriving from climate change. In this direction, the author analyses the fact that risks connected with climate change and the potential contribution of the insurance sector need to be analysed by scientific research in order to plan the correct risk management strategies in the future.
Lease Characteristics, Agency Costs, and Tax Considerations
Authors: Chen Kun-chih , Chi Wuchun , Lobo Gerald , Yong Kevin Ow
Published: June 2018

We examine the determinants that influence managers’ decision as to whether a lease is structured as a financing lease or an operating lease. Specifically, we find that firms with higher marginal tax rates, lower credit ratings, and more severe agency problems are more likely to use both operating leases and financing leases. However, tax considerations and debt capacity have little effect on which of the two types of lease is chosen. More importantly, we find that differences in kinds of agency problemsare reflected in the choice of the type of lease. Our study provides a better understanding of the extent of risks and benefits associated with the use of leased assetsand contributes to the discussion of impending revisions to lease accounting rules by standard-setting bodies.

Continuous- discrete mathematical model for control of growth of a plant population in a given time period under a given budget
Authors: Bhattacharya Dilip Kumar
Published: June 2018

The paper discusses an economically viable way of controlling biomass of a vegetable plant population under the use of fertilizer in a given span of time under a given budget of expenditure. The span of time is divided in some suitable consecutive periods of equal duration P, called cohorts. The treatment is done on the available population of plant at the beginning of each cohort for a suitable time; the continuous dynamics in the change of biomass for this time period is governed by an ordinary differential equation involving total effort exerted in treating the initial population. Taking this improved value at the end of the time period as the initial value, the biomass of the population is allowed to move under its normal continuous dynamics given by Logistic growth equation for the rest of the time of that cohort.  The final concentration of the biomass at the end of the first cohort is obtained by following the above two types of dynamics. This is also considered as the starting biomass for the next cohort. The same process adopted for the first cohort is repeated for calculating the improvement of the biomass in the second cohort and the whole process is repeated till the end of the final cohort is reached. Next an objective function is formed for the given span of time. This measures the net profit in getting improvement in the weight of the biomass less the cost involved in the process of improving the weight of the biomass for the given period of time. As the analysis is done in considering different cohorts at regular intervals of time, so it is a discrete model. As within each cohort, the dynamics takes place continuously, so it is a continuous model too. As a whole, the model is found to be a continuous- discrete model. Hence method of optimal control for continuous-discrete model is used to determine how the treatment at the starting of each cohort be adjusted, depending on the allocated budget, so that the total net profit is maximum.

The Analysis of the Forest Fires in Turkey with Statistical Quality Control Method
Authors: Varol Tugrul , Ertuğrul Mertol , ÖZEL Halil Barış
Published: June 2018

Fire is one of the most serious hazards for forests on earth. Despite each kind of technological development and equipment, fire activity has an increasing trend because of especially climate change and socio-economic reasons. Although fire extinguishing organizations, today, try to suppress this increasing risk with a maximum effort, the big fires in some places cause the enormous areas to get burned.  The fires as big as natural disasters cannot be extinguished most of the time in spite of any efforts or methods when the extreme fire weather conditions come together with inflammable matters and ignition sources.

In this study, the number and area of forest fires in Turkey were investigated through statistical quality control method. Despite the decreasing trend of forest fires in terms of area size, the possibility of large fires always exists in the whole Mediterranean Region due to the socio-economic conditions such as increasing human population, migration and any changes that could affect fire activity in climate conditions. As a result of the study, it is seen that there is an overall increase in the number of fires while the burned area decreases. Out-of-control behaviors in control graphs are not in a continuous trend but sometimes exceed the control limits. This condition is seen to be positive as a trend but also points to the possibility of unexpected annual burned area and the number of fires.
Futebol e televisão: fechem os portões liguem as câmeras - o show vai começar!
Authors: Escher Thiago de Aragão , Reis Heloisa Helena Baldy dos
Published: June 2018

A intenção deste artigo é discutir a tendência da virtualização na assistência das partidas de futebol, pelo exemplo das punições dadas aos torcedores, com partidas com portões fechados porém abertos às câmeras de TV. Como a venda de ingressos não é mais a principal fonte de renda dos clubes, e sim as cotas provenientes das transmissões televisivas, os estádios se mantêm de forma decadente, não observando seus espectadores como possíveis consumidores do espetáculo futebolístico. Enquanto isso, novas formas de telespetacularização são criadas, valorizando as transmissões pela TV que parecem se sobrepor à assistência aos jogos no estádio.

A utilização política dos esportes não é uma novidade. Basta lembrar o período militar brasileiro. Na atualidade, contudo, as transformações da sociedade implicam também em transformações na dimensão política do esporte e da atividade física em geral. Em tempos de globalização, soma-se ao papel, já bem descrito por Norbert Elias, do esporte como descontrole controlado das emoções, outras dimensões simbólicas como por exemplo o culto à competição e ao vencedor, a existência de um pretenso espaço com regras claras e justas, o culto à eterna juventude e um corpo perfeito, e a possibilidade de ascensão social para representantes dos setores mais pobres da sociedade que demonstrem “dons” atléticos.

O futebol é, inegavelmente, parte da vida dos brasileiros. O termo no masculino é literal e intencional, pois ser homem em nossa sociedade parece exigir, entre outras coisas, ao menos que o sujeito tenha um time de futebol para torcer. As mulheres também torcem e jogam, mas sua participação parece ínfima diante da mobilização masculina para esse esporte. De tão culturalmente enraizado, até nos passa a sensação de que eles nasceram assim, com o gene do futebol inscrito em seus pés. Esse “universo da bola” possui um saber público e dinâmico do tipo “zona de rebaixamento; rodadas e classificações; quem sobe e quem desce nas divisões; rodada da semana e seus resultados”, todos com uma lógica própria de funcionamento que demanda uma dedicação muitas vezes incompreensível por nós, mulheres. Uma norma comum parece ser que todo bom torcedor precisa saber narrar, ao menos, um momento marcante do futebol para sua vida: aquela jogada inesquecível, o gol mais emocionante, aquele sabor de “virada” no último minuto do jogo.

Nesse contexto procura-se mostrar a velocidade como uma grandeza técnico-tática, perceptiva e informacional, que necessita ser estimulada através de exercícios cada vez mais “complexos e inteligentes”, para poder ser desenvolvida.
Short Version of 'The Brain, Explained': A Response Process Theory of Brain Function
Authors: Rappoport Ari
Published: June 2018

Understanding brain function is one of the most important open problems in science today. At present, there is no concrete theory for how the brain works. Here, a theory is presented that provides a detailed mechanistic biological account of the brain’s capacities. Brain function is managed by a response (R) process that is structurally similar to the immune response, and shows anatomical and molecular specificity. Different R process stages utilize different cortical layers, hippocampus fields, basal ganglia paths, GABAergic interneurons, cerebellum paths, and molecular agents such as dopamine, serotonin and opioids. We show how the R process supports hierarchical action sequences, language and thought. The theory is supported by a large body of experimental evidence in many modalities, and accounts for virtually all of the major facts known about the brain at the system level.
Carapanosins D—F from the Seeds of Andiroba (Carapa guianensis, Meliaceae) and Their Effects on LPS-Activated NO Production
Authors: Inoue Takanobu , Ohmori Shoko , Kikuchi Takashi , Yamada Takeshi , Tanaka Reiko
Published: June 2018

A novel nor-phragmalin-type limonoid, named carapanosin D (1), and two novel mexicanolide-type limonoids, carapanosins E (2) and F (3), were isolated from the seeds oil of Carapa guianensis AUBLET (andiroba), a traditional medicine in Brazil and Latin American countries. Their structures were elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques and HRFABMS. Compounds 1—3 were evaluated for their effects on the production of NO in LPS-activated mouse peritoneal macrophages. The NO inhibitory assay suggested that compound 2 may be valuable as potential inhibitors of macrophage activation.
Gambogenic Acid Triggers Apoptosis of Human Nasopharyngeal Carcinoma CNE-2Z Cells through Activating Volume-Sensitive Outwardly Rectifying Chloride Channels
Authors: Su Jingjing , Xu Ting , Jiang Genling , Liang Mengru , Cheng Hui , Hou Mei , Li Qinglin
Published: June 2018

Nasopharyngeal carcinoma (NPC) has not been thoroughly studied, and the pathogenesis of NPC is unclear. Scientists have neither discovered effective therapies nor achieved a desirable prognosis. Some studies have found that the regulation of intra- and extracellular ion channels hinges directly on cell apoptosis, and treatment with Gambogenic acid (GNA) brings changes to the volume-sensitive outwardly rectifying chloride (VSOR Cl-) current of CNE-2Z cells recorded by the patch clamp method. Nevertheless, rarely have any researchers probed into the relevance between this variation and the anti-tumor mechanism of GNA. This paper is suggested that GNA activates the VSOR Cl- current on the CNE-2Z cell membrane, and the activation of VSOR Cl- currents by GNA in CNE-2Z cells is blocked by the chloride channel blockers DIDS and DCPIB. GNA induces the down-regulation of GRP78 and up-regulation of ATF4 as well as chop proteins, which is evidence for the induction of CNE-2Z cell apoptosis, and this correlates with ER stress. GNA can activate the VSOR Cl- channel and lead to the occurrence of ER stress, thus inducing the apoptosis of CNE-2Z cells and inhibiting the proliferation of CNE-2Z cells.

This mixed method study determined the essential tools and services required for research data management to aid academic researchers in fulfilling emerging funding agency and journal requirements. Focus groups were conducted and a rating exercise was designed to rank potential services. Faculty conducting research at the University of Toronto were recruited; 28 researchers participated in four focus groups from June– August 2016. Two investigators independently coded the transcripts from the focus groups and identified four themes: 1) seamless infrastructure, 2) data security, 3) developing skills and knowledge, and 4) anxiety about releasing data. Researchers require assistance with the secure storage of data and favour tools that are easy to use. Increasing knowledge of best practices in research data management is necessary and can be supported by the library using multiple strategies. These findings help our library identify and prioritize tools and services in order to allocate resources in support of research data management on campus.
POLÍTICA DE FUSÃO DE ENTIDADES HOSPITALARES EM PORTUGAL: AVALIAÇÃO DA PRODUTIVIDADE
Authors: Nunes Alexandre Morais
Published: June 2018

Esta pesquisa desenvolve um exercício de avaliação da produtividade em 18 centros hospitalares, criados através de um processo de fusão de entidades hospitalares decorrido gradualmente entre os anos 2006 e 2011. O objetivo principal deste estudo é verificar se ocorreu, como esperado, uma melhoria na produtividade após a introdução dessa política de fusão. Como metodologia foi aplicado o índice de Malmquist, que mede a produtividade total dos fatores entre dois pontos de dados em termos de escores de funções de distância baseados no uso prévio de um método não paramétrico para estimar as funções de fronteira (no caso a Análise Envoltória de Dados - DEA). Como resultados, se conclui que a constituição de 18 centros hospitalares tem gerado, em termos de efeitos imediatos, uma melhoria da produtividade, porém restringida a partir do ano 2011, por influência do programa de intervenção econômica externa aplicado a Portugal pelo Fundo Monetário Internacional, Banco Central Europeu e Comissão Europeia.

CSR Practice and Asymmetry Information of Indonesian Public Listed Companies
Authors: Usman Berto , Yennita Yennita
Published: June 2018

Our study examines the relationship between Corporate Social Responsibility (CSR) practice and asymmetry information in the Indonesian Stock Exchange. We conjecture that these two concepts are negatively associated. To empirically test their association, we use the availability of CSR report, environmental score, and social score as the surrogate indicators of CSR practice. While, bid/ask spread (BAS) and price volatility (PV) are employed as the proxies of Asymmetry information. Using the quarterly data spans from the second quarter of 2012 to the fourth quarter of 2016, we collect as many as 39 companies that voluntarily disclosed their CSR-related information. To investigate the importance of CSR practice in the truncation of asymmetry information, we use the univariate analysis and multivariate analysis. We find that CSR practice is negatively associated with the asymmetry information. Our results remain consistently after we control for the firm-specific, year, and industry fixed-effect.

Published: June 2018

A caracterização morfométrica de bacias hidrográficas fornece informações importantes para o planejamento da conservação da água e demonstra a susceptibilidade à erosão e a capacidade de uso do solo. O objetivo do estudo foi caracterizar as propriedades morfométricas da bacia do Rio Itajaí (SC), utilizando-se de dados SRTM e ambiente SIG, por meio da obtenção de parâmetros geométricos, de relevo e de rede de drenagem. Os dados evidenciaram que a bacia hidrográfica é de 5.ª ordem e apresenta forma alongada com relevo ondulado. O estudo apontou baixa capacidade e densidade de drenagem, apresentando um padrão dendrítico, com poucas ramificações. A bacia compreende canais transicionais, regulares e irregulares, o que indica media taxa de transporte de sedimentos. A análise dos dados mostrou os atributos da bacia diante da dinâmica ambiental, permitindo inferir que a bacia do Rio Itajaí é pouco sujeita a enchentes. Entretanto existe a necessidade de estudos complementares das suas microbacias para verificar efetivamente o seu potencial quanto à ocorrência de enchentes, inundações ou alagamentos.

Published: June 2018

O comportamento germinativo das espécies florestais nativas tem exigido atenção no meio científico, principalmente na obtenção de informações referentes às condições ideais de germinação e utilização em ambientes de restauração e recuperação de áreas degradadas. Dessa forma, o presente estudo teve como objetivo avaliar o efeito da idade das árvores matrizes de Vernonanthura discolor (Spreng.) H. Rob. (Asteraceae) sobre o poder germinativo e o índice da velocidade de germinação (IVG) de sementes submetidas a diferentes períodos de armazenamento. Foram selecionadas quatro árvores matrizes para a coleta de sementes, das quais duas de aspecto adulto-senil (A1 e A2) e duas de aspecto adulto-jovem (B1 e B2). Foram avaliados o poder germinativo e o IVG com períodos de 30 e 75 dias de armazenamento. Nas sementes armazenadas por 30 dias, o percentual germinativo foi estatisticamente superior para as matrizes A, porém o IVG foi superior nas matrizes B. O experimento apontou que as espécies adulto-senis mostraram melhores condições de germinação, assim como que fatores associados a características fenológicas e maturidade das matrizes podem alterar a taxa germinativa.

DNA-Minor Groove Binding Agents as Anti-Tubercular Probes. Old Tools for a New Challenge?
Authors: Brucoli Federico
Published: June 2018

Tuberculosis, an ancient infectious disease caused by Mycobacterium tuberculosis, ranks as
one of the top ten killers worldwide. The limited number of validated targets and scarce therapeutic options
demand that renewed efforts should be made to identify tuberculosis drugs with novel mechanisms
of action. To this end, mycobacterial DNA might represent a potential target for the development of effective
anti-tubercular compounds. In particular, the minor groove of DNA offers an important recognition
site for small-molecules that can be programmed to bind to this region in a sequence-selective
manner to disrupt mycobacterial transcription factors activity and ultimately cause bacterial cell death.

This review describes the structural features of the DNA-minor groove, the requirements for small
molecules to bind to this site and the remarkable biophysical and antibacterial properties of DNA-minor
groove binding agents, including netropsin, distamycin and their poly-heterocyclic analogues, diamidines,
benzimidazole-containing molecules, duocarmycins and pyrrolo[2,1-c][1,4]benzodiazepines
(PBDs). Furthermore, the ability of selected heterocyclic-polyamides and PBDs to significantly inhibit
the growth of pathogenic, slow-growing M. tuberculosis and other non-pathogenic mycobacterial strains
is highlighted. In summary, DNA-minor groove binding agents may serve as molecular scaffolds for the
design of highly efficient probes to treat M. tuberculosis infections.

The MMIC ED02AH technology have been developed specifically for microwave applications
up to millimeter waves, and for high-speed digital circuits. The use of a single branch of a power
amplifier can produce high distortion. In the present paper, the Linear amplification with nonlinear
components (LINC) method is introduced and applied as a solution to linearize the power amplifier, it can
simultaneously provide high efficiency and high linearity. To validate the proposed approach, the design
and characterization of a 5.25 GHz LINC Power Amplifier on MMIC technology is presented.

Results:

Good results have been achieved, and an improvement of about 37.50 dBc and 59 dBc
respectively is obtained for the Δlower C/I and Δupper C/I at 5.25 GHz.

Conclusion:

As a result of this method, we can reduce the Carrier Power to Third-Order Intermodulation
Distortion Power Ratio. Excellent linearization is obtained almost 37.6 dBc for Δlower C/I and 58.8 dBc
for Δupper C/I.
Characterizing the Digital Health Citizen: Mixed-Methods Study Deriving a New Typology (Preprint)
Authors: Powell John , Deetjen Ulrike
Published: June 2018

BACKGROUND

A key challenge for health systems harnessing digital tools and services is that of digital inclusion. Typically, digital inequalities are conceptualized in relation to unequal access or usage. However, these differences do not fully explain differences in health behavior as a result of health-related internet use.

OBJECTIVE

Our objective was to derive a new typology of health internet users based on their antecedent motivations and enablers, to explain how individuals’ different orientations influence their health behavior.

METHODS

We used a mixed-methods design using (1) qualitative data from 43 semistructured interviews about individuals’ general and health-related internet use, and how this influenced their health perception and their help-seeking decisions, and (2) quantitative data from the Oxford Internet Surveys (OxIS), a household survey of 2150 adults in England about their internet use and other characteristics. We used the interview data to identify constructs that described motivations and enablers affecting how internet use shaped respondents’ health perception and health service use. We then used these constructs to identify variables in OxIS, which provided a quantitative measure of these constructs. We then undertook a hierarchical cluster analysis of these constructs, using the numerical variables, to derive a proposed typology of health information seekers.

RESULTS

Both the qualitative findings and the subsequent cluster analysis suggested the existence of 6 types of individuals, categorized as learners, pragmatists, skeptics, worriers, delegators, and adigitals. Learners had a strong desire to understand health better. They used the internet to make decisions about whether they needed to see a professional and to learn about their and others’ health. Pragmatists primarily used the internet to decide whether seeing a doctor was worthwhile. Skeptics were skeptical of physicians and the medical system and valued the internet for solving health problems that doctors may not be able to deal with. Worriers found it difficult to interpret health information online, described health information seeking online as frightening, and reported a critical attitude toward online health information despite seeking it frequently. Delegators comprised nonusers and users valuing the internet as an information source, but not necessarily wanting or being able to use the internet themselves. Adigitals comprised many nonusers, but also users, who did not see the internet as a useful information tool and presented strong views on its low suitability for health care.

CONCLUSIONS

This research supports a shift in the understanding of the digital divide in health, away from only access and usage issues, toward also conceptualizing an outcomes divide, whereby different types of health behavior result from the differing orientations of internet users accessing online health information. This new typology can be used to inform digital inclusion policies in health systems.
Bovine vitreous gel can reactivate replicative senescence of human dermal fibroblast

The most influential factor in the poor healing of chronic ulcers is replicative senescence of fibroblasts that are unresponsive to TGF-β1 stimulation. Cellular replicative senescence can be induced by cultivating normal human dermal fibroblasts (HDFs) in a serum-starved medium. In addition, increasing microenviroment mechanical forces by hyaluronic acid can ameliorate the TGF-β1 signaling of these senescent cells. One of natural resources of hyaluronic acid is bovine vitreous gel. In order to evaluate the effect of bovine-vitreous gel on replicative senescence of fibroblasts, we used various levels of bovine vitreous gel diluted in Dulbecco’s modified Eagle’s medium to stimulate cellular activities of serum-starved HDFs. Those cellular activities were compared to the control media, standardized hyaluronic acid, and to normal HDFs. Our results show that replicative senescence of HDFs treated with 50% bovine vitreous gel exhibited a significantly higher proliferation index, migration rate, and collagen deposition than those cultured in control media, and they displayed an equal level of cellular activity with the HDFs exposed only to standardized hyaluronic acid. We concluded that bovine vitreous gel can be used to stimulate replicative senescence of HDFs and therefore a potential candidate material to stimulate healing of chronic ulcers.

O presente artigo tem por objetivo relatar a experiência da inserção do psicólogo em um programa de Residência Multiprofissional em Saúde da Mulher. O trabalho se baseou nas atividades das duas primeiras turmas do programa, sendo cada uma composta por 16 residentes das áreas de educação física, enfermagem, farmácia, nutrição e psicologia. Durante o primeiro ano, os residentes atuavam na Atenção Básica e, no segundo ano, na Atenção Secundária e Terciária. A participação da Psicologia nos diferentes campos de abrangência da residência motivou diversos questionamentos sobre o seu papel. Neste contexto destacamos os desafios e as contribuições da participação do Psicólogo na equipe multiprofissional, especialmente quanto no atendimento às especificidades da saúde da mulher. residência multiprofissional; psicologia; saúde da mulher.
Clínica, Música e Tempo: Agenciamentos Possíveis para uma Experiência Afetiva
Authors: Rosa Gessica Carneiro da , Moehlecke Vilene
Published: June 2018

Esse artigo apresenta um fragmento teórico-conceitual do trabalho de conclusão de curso elaborado a partir de uma experiência de estágio profissional em Psicologia. A forte presença da arte em meio às práticas clínicas suscitou uma série de conexões, produzindo desterritorializações e problematizações de velhas dicotomias, indicando aspectos afetivos, dinâmicos, temporais, de intensidade, nem sempre passíveis de verbalização. Com as contribuições de autores como Regina Benevides, Daniel Stern, Gilles Deleuze e Félix Guattari, as linhas que seguem cartografam os processos de produção subjetiva, evidenciando as ressonâncias entre clínica e música, o modo como a dimensão coletiva se manifesta nos atendimentos ditos individualizados e a possibilidade das experiências afetivas surgirem com a sintonia afetiva entre paciente e estagiária-terapeuta. Ao pesquisarmos com o método cartografia, assumimos a indissociabilidade do fazer e conhecer. Portanto, ainda que seja um recorte conceitual, serão destacadas as vicissitudes da prática do estágio.

Neste artigo, objetivamos relatar a experiência de uma pesquisa participativa, interventiva e cartográfica em saúde mental na atenção básica, problematizando os modos de conhecer e explorando as potencialidades e afetos despertados em campo. Trazemos a trajetória da pesquisa “Qualificação da Saúde Mental na Atenção Básica: análise das práticas de equipes da Região 10-Macrometropolitana/RS a partir do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB)”, discutindo especificamente o processo em um dos municípios envolvidos. Adentramos o campo, descentralizando gestos acadêmicos em contato com os descentramentos da atenção básica. Experimentamos composições nesse nível porta de entrada do sistema de saúde, junto a usuários, trabalhadores e gestores, abrindo-nos aos imprevisíveis que exigem invenção e construção de um comum em meio às comunidades e territórios. Tal perspectiva articula pesquisa e saúde mental na busca por modos clínicos e pesquisantes mais autônomos, singulares e produzidos em conjunto no campo.Palavras-chave: Cartografia; Saúde Mental; Atenção Básica.
DATABASE SYSTEM SUGGESTIONS FOR THE INTERNET OF THINGS (IOT) SYSTEMS
Authors: KALAY Mustafa Utku
Published: June 2018

Internet of
Things (IoT) is an interconnection of different types of information assets in
which data is continuously generated and transmitted over the Internet.
Technologies of the sensor, RFID, GPS, mobile devices, and Internet-enabled
actuators play a significant role in IoT systems. IoT brings out new challenges
in terms of data and information management because it is not easy to collect
and manage a large amount of heterogeneous data that is aggregated at very high
velocity as well as to retrieve and manage the information that is hidden
within this large volume of data. In this
paper, I discuss the main factors affecting the efficiency of data management
in IoT systems, specifically query processing and transaction management. There
are many lessons learned from traditional database systems, distributed
systems, and sensor networks, however, traditional solutions are often
inadequate to meet the needs of applications in such a complex ecosystem,
namely IoT. In traditional database systems, for instance, query operations are
usually local, and execution costs depend on the current processor power and
other resource constraints (i.e. memory). On the other hand, transaction
management mechanisms guarantee the ACID properties in order to provide overall
data integrity. It is apparent that different types of IOT applications that
operate on heterogeneous, streaming, real-time, and geographically distributed
large data will significantly change the well-known aspects of querying and
transaction management. Context-aware querying, distributed querying, MapReduce
computing model and flexible transaction models such as web-based transaction
handling are some of the current issues discussed in this paper. With the succinct yet comprehensive information
presented in this work, I intend to provide a guide for researchers in the IoT
systems, especially in the context of database systems.
