Consumer Evaluation of the Quality of Online Health Information: Systematic Literature Review of Relevant Criteria and Indicators (Preprint)
Authors: Sun Yalin , Zhang Yan , Gwizdka Jacek , Trace Ciaran B.
Published: October 2018

BACKGROUND

As the quality of online health information remains questionable, there is a pressing need to understand how consumers evaluate this information. Past reviews identified content-, source-, and individual-related factors that influence consumer judgment in this area. However, systematic knowledge concerning the evaluation process, that is, why and how these factors influence the evaluation behavior, is lacking.

OBJECTIVE

This review aims (1) to identify criteria (rules that reflect notions of value and worth) that consumers use to evaluate the quality of online health information and the indicators (properties of information objects to which criteria are applied to form judgments) they use to support the evaluation in order to achieve a better understanding of the process of information quality evaluation and (2) to explicate the relationship between indicators and criteria to provide clear guidelines for designers of consumer health information systems.

METHODS

A systematic literature search was performed in seven digital reference databases including Medicine, Psychology, Communication, and Library and Information Science to identify empirical studies that report how consumers directly and explicitly describe their evaluation of online health information quality. Thirty-seven articles met the inclusion criteria. A qualitative content analysis was performed to identify quality evaluation criteria, indicators, and their relationships.

RESULTS

We identified 25 criteria and 165 indicators. The most widely reported criteria used by consumers were trustworthiness, expertise, and objectivity. The indicators were related to source, content, and design. Among them, 114 were positive indicators (entailing positive quality judgments), 35 were negative indicators (entailing negative judgments), and 16 indicators had both positive and negative quality influence, depending on contextual factors (eg, source and individual differences) and criteria applied. The most widely reported indicators were site owners/sponsors; consensus among multiple sources; characteristics of writing and language; advertisements; content authorship; and interface design.

CONCLUSIONS

Consumer evaluation of online health information is a complex cost-benefit analysis process that involves the use of a wide range of criteria and a much wider range of quality indicators. There are commonalities in the use of criteria across user groups and source types, but the differences are hard to ignore. Evidently, consumers’ health information evaluation can be characterized as highly subjective and contextualized, and sometimes, misinformed. These findings invite more research into how different user groups evaluate different types of online sources and a personalized approach to educate users about evaluating online health information quality.

Published: October 2018

BACKGROUND

With the availability and capabilities of varied technologically enhanced learning activities, the blended learning approach has become increasingly popular in interprofessional education. The combined use of different technologically enhanced learning activities has not been fully examined, particularly to determine the effects of instructional sequences for effective learning outcomes.

OBJECTIVE

The objective of this study was to investigate whether the instructional sequences of a blended learning approach can improve students’ learning outcomes on interprofessional competencies.

METHODS

A randomized controlled study was conducted with 40 interprofessional health care teams. These teams undertook three technologically enhanced learning activities—Web-based instruction (WI), virtual reality (VR), and simulation exercise (SE)—after random assignment to three groups based on three different instructional sequences (WI-VR-SE, WI-SE-VR, and SE-WI-VR). Pretests and posttests were conducted to evaluate the students’ learning outcomes on interprofessional competencies.

RESULTS

A total of 198 participants from the three groups completed the questionnaires. All three groups reported significant improvement in their levels of self-efficacy (P<.05) and attitudes (P<.001) toward interprofessional team care about 1 month after the interprofessional learning activity. Although no significant difference was found (P=.06) between the WI-VR-SE and WI-SE-VR groups in the self-efficacy posttests, participants in the SE-WI-VR group reported significantly lower (P<.05) posttest scores than those in the WI-SE-VR group. The majority of the participants (137/198, 69.1%) selected the instructional sequence “WI-VR-SE” as their top preference.

CONCLUSIONS

This study shows that the instructional sequence of a blended learning approach can have a significant impact on students’ learning outcomes. The learning of concepts from WI followed by problem-solving activity in the SE was found to be a more effective learning sequence than the reverse sequence. We recommend that future studies focus on scaffolding students’ learning when planning instructional sequences for technologically enhanced learning activities within blended learning environments.
Patient Rounds With Video-Consulted Relatives: Qualitative Study on Possibilities and Barriers From the Perspective of Healthcare Providers (Preprint)
Authors: Østervang Christina , Vestergaard Lene Vedel , Dieperink Karin Brochstedt , Danbjørg Dorthe Boe
Published: October 2018

BACKGROUND

In cancer settings, relatives are often seen as a resource as they are able to support the patient and remember information during hospitalization. However, geographic distance to hospitals, work, and family obligations are reasons that may cause difficulties for relatives’ physical participation during hospitalization. This provided inspiration to uncover the possibility of telehealth care in connection with enabling participation by relatives during patient rounds. Telehealth is used advantageously in health care systems but is also at risk of failing during the implementation process because of, for instance, health care professionals’ resistance to change. Research on the implications for health care professionals in involving relatives’ participation through virtual presence during patient rounds is limited.

OBJECTIVE

This study aimed to investigate health care professionals’ experiences in using and implementing technology to involve relatives during video-consulted patient rounds.

METHODS

The design was a qualitative approach. Methods used were focus group interviews, short open interviews, and field observations of health care professionals working at a cancer department. The text material was analyzed using interpretative phenomenological analysis.

RESULTS

Field observational studies were conducted for 15 days, yielding 75 hours of observation. A total of 14 sessions of video-consulted patient rounds were observed and 15 pages of field notes written, along with 8 short open interviews with physicians, nurses, and staff from management. Moreover, 2 focus group interviews with 9 health care professionals were conducted. Health care professionals experienced the use of technology as a way to facilitate involvement of the patient’s relatives, without them being physically present. Moreover, it raised questions about whether this way of conducting patient rounds could address the needs of both the patients and the relatives. Time, culture, and change of work routines were found to be the major barriers when implementing new technology involving relatives.

CONCLUSIONS

This study identified a double change by introducing both new technology and virtual participation by relatives at the same time. The change had consequences on health care professionals’ work routines with regard to work load, culture, and organization because of the complexity in health care systems.

Published: October 2018

BACKGROUND

Cardiac rehabilitation is recommended by the European Society of Cardiology (ESC) after the initial coronary event for patients with acute coronary syndrome. However, attendance to CR programs and especially maintenance programs after out-patient CR are less than 50%. A possible approach to increase adherence and attendance to maintenance CR programs is telerehabilitation. In its most comprehensive format, telerehabilitation includes telemonitoring (i.e. remote monitoring), tele coaching (i.e. coaching from a distance by email/SMS/telephone), social interaction, and e-learning. The specific role and value of e-learning in telerehabilitation for CAD patients were hardly assessed.

OBJECTIVE

The objective of this study was to create a platform with information and educational videos presented by doctors, nurses, physiotherapists and other care actors. The aim of this study is to investigate the proportion of patients who enter an e-learning platform and whether sociodemographic and medical factors influence cardiac-based e-learning usage.

METHODS

Patients diagnosed with a coronary artery disease were included in a multi-center randomized controlled trial (N = 985). All patients obtained conventional cardiac care, while 508 patients received in addition to standard care a one-month access to an e-learning platform with tailored educational information. This information consisted out of 20 main video units, all with content relevant in secondary prevention for ischemic heart disease. All platform data such as the number of log-ins per patient, total time on the platform, type and number of videos viewed, were logged.

RESULTS

508 patients (82.87% male; aged 62±9 years) were included in the intervention group of this study while 264 (51.97%) participants entered the platform. Median of platform consultation was 2 [1-3] during the one-month period and patients spent 22.50 [5.22-49.56] min watching 7.5 [3-14] video units. Both multiple as single logistic regression showed that in-center CR participation (p=.01) and educational attainment (p=.02) significantly affect the chance that a patient entered the e-learning platform. Furthermore, a significant influence of age (p = .05) was found on time spent watching videos.

CONCLUSIONS

The results indicate the interest in the use of an e-learning platform for providing additional medical specific information about coronary diseases. However, there are substantial differences in usage among patients.

Published: October 2018

BACKGROUND

Numerous free and low-cost mobile apps for the care management of kidney disease have become available in recent years. Although these appear to be promising tools, they have not been evaluated comparatively based on standard mobile app metrics, and thus, limited evidence is available regarding their efficacy. This study systematically cataloged and assessed mobile apps designed to assist medication compliance and nutrition tracking that are useful to the chronic kidney disease (CKD) and the end-stage renal disease (ESRD) patients who are on dialysis.

OBJECTIVE

The objective of this study was to comprehensively evaluate mobile apps used for medication compliance and nutrition tracking for possible use by CKD and ESRD patients.

METHODS

A systematic review framework was applied to the search, screening, and assessment of apps identified and downloaded from the iOS and Android app stores. We selected apps using 13 relevant search terms, narrowed down based on a set of inclusion and exclusion criteria, and then used the Mobile App Rating Scale (MARS), a widely adopted app evaluation tool to assess the effectiveness of apps. The internal consistency and interrater reliability were tested using Cronbach alpha and interclass correlation coefficients (ICCs), respectively.

RESULTS

The MARS total score had excellent internal consistency (Cronbach alpha=.90) and a moderate level of interrater reliability (2-way mixed ICC 0.65). Overall, 11 out of the 12 reviewed apps met the minimum acceptable score of 3.0 in MARS rating. The 3 apps with the highest combined scores were My Kidneys, My Health Handbook (MARS=4.68); My Food Coach (MARS=4.48); and National Kidney Foundation Malaysia (MARS=4.20). The study identified 2 general weaknesses in the existing apps: the apps fell short of accommodating advanced interactive features such as providing motivational feedback and promoting family member and caregiver participations in the app utilization.

CONCLUSIONS

The MARS rating system performed well in the app evaluation. The 3 highest ranked apps scored consistently high across the 5 dimensions specified in MARS. These apps were developed in collaboration with reputable organizations and field experts, demonstrating the importance of expert guidance in developing medical apps.

The aims of this study to determine the effect of honey bees (Apis dorsata) to prevent the decrease of femur density in  ovariohysterctomized rats as animal model of osteoporosis by Scanning Electron Microscope (SEM). This study used 20 adult female white rats (Rattus norvegicus) with body weight 300 gr. Divided into 5 groups, negative control group (P0-), not in ovariohysterectomy,  only given aquadest 1.5 ml/day ; Positive control group (P0 +), in ovariohysterectomy,  only given aquadest 1.5 ml/day; Treatment group 1 (P1), in ovariohysterectomy and given honey 1 gram / kg BB + 1.5 ml aquadest; Treatment group 2 (P2), in ovariohysterectomy and given honey 2 grams / kg BB + 1.5 ml aquadest; Treatment group 3 (P3), in ovariohysterectomy and given honey 4 grams / kg BB + 1.5 ml aquadest. After 12 weeks, all rats were sacrified for removal of the femur and performed by SEM. Analysis of SEM showed that mice administered honey with a dose of 4 grams / kg BW (P3) showed bone density approaching negative control treatment (P0-), ie, ovariohysterectomized rats. P3 showed the most less bone porosity than other treatment groups. The largest and most uniformly distributed porosity was shown by the positive control group (P0 +). The best results with the smallest quantity and size of the porosity of femur is in P3 group. In conclusion, honey (Apis dorsata) can prevent the decrease in bone density of the femur by Scanning Electron Microscope (SEM).

Published: October 2018

Background and objectives

Biopsies taken at deceased donor kidney procurement continue to be cited as a leading reason for discard; however, the reproducibility and prognostic capability of these biopsies are controversial.

Design, setting, participants, & measurements

We compiled a retrospective, single-institution, continuous cohort of deceased donor kidney transplants performed from 2006 to 2009. Procurement biopsy information—percentage of glomerulosclerosis, interstitial fibrosis/tubular atrophy, and vascular disease—was obtained from the national transplant database. Using univariable, multivariable, and time-to-event analyses for death-censored graft survival, we compared procurement frozen section biopsy reports with reperfusion paraffin-embedded biopsies read by trained kidney pathologists (n=270). We also examined agreement for sequential procurement biopsies performed on the same kidney (n=116 kidneys).

Results

For kidneys on which more than one procurement biopsy was performed (n=116), category agreement was found in only 64% of cases (κ=0.14). For all kidneys (n=270), correlation between procurement and reperfusion biopsies was poor: overall, biopsies were classified into the same category (optimal versus suboptimal) in only 64% of cases (κ=0.25). This discrepancy was most pronounced when categorizing percentage of glomerulosclerosis, which had 63% agreement (κ=0.15). Interstitial fibrosis/tubular atrophy and vascular disease had agreement rates of 82% (κ=0.13) and 80% (κ=0.15), respectively. Ninety-eight (36%) recipients died, and 56 (21%) allografts failed by the end of follow-up. Reperfusion biopsies were more prognostic than procurement biopsies (hazard ratio for graft failure, 2.02; 95% confidence interval, 1.09 to 3.74 versus hazard ratio for graft failure, 1.30; 95% confidence interval, 0.61 to 2.76), with procurement biopsies not significantly associated with graft failure.

Conclusions

We found that procurement biopsies are poorly reproducible, do not correlate well with paraffin-embedded reperfusion biopsies, and are not significantly associated with transplant outcomes.

Authors: Yu Tiffany M , Dugel Pravin U , Haller Julia A , Kaiser Peter K , Arnold Renée JG
Published: October 2018

Background:
Vitreomacular traction (VMT) treatment options include watchful waiting, vitrectomy and intravitreal ocriplasmin injection (Jetrea
®
). This analysis used results from the recently completed OASIS randomized clinical trial to evaluate the 2-year budget impact of ocriplasmin injection availability for treatment of Stage I or II VMT without epiretinal membrane formation in a modeled US health plan.
Materials & methods:
 VMT prevalence, treatment patterns and disease resolution rates were from literature, a US retinal-specialist survey and the OASIS trial. Medicare payment rates were applied and a national scenario analysis was conducted.
Results:
With ocriplasmin available, vitrectomy use and complications-related costs decreased. Budget impact of ocriplasmin to the health plan was US$143,599 over 2 years or US$0.0060 per-member per-month.
Conclusion:
Ocriplasmin was projected to be minimally cost-additive at US$0.0060 per-member per-month over 2 years.

Published: October 2018

Beef Loin, Strip Loins (IMPS #180; n = 20) with marbling scores between Modest00 and Modest30 at the 12th and 13th rib interface of the M. longissimus thoracis et lumborum (LL) were collected. Each strip loin was fabricated into 6 samples taken perpendicular to the long axis of the LL from the 13th thoracic vertebra to the fifth lumbar vertebra with the cut made on the anterior side of the respective vertebra. A Computer Vision System Cold Camera measured the LL cross-section of each sample location for USDA marbling score, marbling distribution, average marbling fleck size, LL area, LL length (distance medial to lateral), and LL width (distance dorsal to ventral). In the present study, mean LL marbling score decreased (P < 0.05) from the second lumbar vertebrae location to the fifth lumbar vertebrae location. Marbling size and marbling distance were the smallest (P < 0.05) in samples from the 13th thoracic vertebrae location. The LL area and width was largest (P < 0.05) for the samples from the most anterior location and thus decreased (P < 0.05) as the samples became more posterior. Samples from the most posterior end of the strip loin were the longest (P < 0.05) in length. It was observed that marbling score, distribution, and size, as well as, LL area, length, and width vary from anterior to posterior in the strip loin which can have potential marketing implications for food service distributors and retailers.

Adult intelligence capabilities, associated with brain tissue development have reached 50 percent when he was 4 years old. The rapid development of brain tissue occurs when the child is 8 years old and reaches its peak when he is 18 years old. After that, although the improvement of nutrition will not affect cognitive development. This means that developments occurring in the first 4 years are as great as the development that occurred over the next 14 years. The first 4-year period is a critical period for children because it is very influential on the development of the next period until adulthood, while the golden period only comes once. Optimization of early childhood education, ie education of children at the age of 4 years first becomes very important. In fact the importance of early education is still not understood by some people. The direction and guidance of the importance of early education is required. This community service program provides direction and guidance on the importance of early childhood education to communities in kampung Bulak, Pondok Gede - Bekasi.

O domínio da linguagem científica é uma competência essencial tanto para a prática da ciência quanto para o seu aprendizado. Neste sentido, aprender ciências requer que os estudantes sejam capazes de estabelecer relações entre avaliar conhecimentos e métodos, avaliar hipóteses e trabalhar com dados dentro da grande estrutura que organiza o conhecimento científico escolar. Partimos da ideia de que a apropriação da linguagem científica e a comunicação verbal só são possíveis por meio de algum gênero textual. Entendemos que é pelo uso da linguagem em seus diversos gêneros textuais e das interações discursivas que professores e estudantes constroem as bases para um ensino cuja proposta vise à alfabetização científica. Assim, objetivou-se nesse trabalho identificar os diferentes gêneros textuais presentes em uma sequência didática investigativa (SDI) voltada ao ensino do conceito de biodiversidade e alguns conceitos de ecologia atrelados. A SDI prioriza a resolução de problemas científicos com o objetivo de promover situações argumentativas e explicativas. Dessa forma, ensinar linguagem no ensino de ciências requer a mobilização de diferentes gêneros textuais para dar suporte ao estudante na construção de significados e no processo alfabetização cientifica.

Resumo Considerando o interesse na temática da arenização no sudoeste do Rio Grande do Sul, Brasil e o estímulo à reflexão, pensa-se que é fundamental expor e discutir os critérios que estruturam o(s) conceito(s) de desertificação, através da análise de como este conceito tem sido apresentado nas pesquisas científicas, nos livros didáticos e na prática universitária. Quando se busca a compreensão da gênese e as bases que forjaram o conceito do processo denominado desertificação, procura-se o balizamento a partir de dois critérios essenciais para o estudo de qualquer processo: o espaço geográfico e o tempo de sua ocorrência. A partir da análise desses dois critérios e das alterações provocadas nas sociedades humanas percebem-se significativas diferenças nos conceitos de desertificação, assim como em relação as propostas de combatê-la. Sendo assim, inicialmente este artigo têm a intenção de incitar a reflexão no que se refere a essas diferenças, trazendo algumas bases referenciais, o uso desses conceitos em livros didáticos de maior uso na rede escolar e a produção dos alunos de pós-graduação do curso de Mestrado em Geografia da UFRGS, na disciplina denominada Desertificação: questão ambiental. Palavras chave: desertificação, arenização, ambiental.Abstract The word desertification has been repeatedly applied to southwestern Rio Grande do Sul, Brasil. This paper questions if this is the right word to use. Below, we review how this word is used in the scientific literature, textbooks and in universities. For all of Geography the meaning of a word must be provided in its both spatial and temporal dimensions. Spatially desertification has been used to arid, semi-arid, semi-wet regions. Examples of this are found in the northeast of Brazil and the Sahel in Africa. The temporal use of desertification is perhaps harder to be as precise, but has been generally used for different time scales. Examples of this are the desertification in a tropical zone of Africa, identified since 1949, the desertification in Brazil identified since 1970 and in others places of the world where the desertification is associated with the global climate change of the Quatemary Period. Key words: desertification, enviromental

Este artigo trás à reflexão os processos sócio-espaciais envolvidos nos atuais projetos de  refuncionalização urbana, destacando as estratégias de preservação do patrimônio histórico edificado e de reintegração de áreas urbanas abandonadas, sobretudo  nos Centros  Históricos consolidados pela industrialização. O gerenciamento político e empresarial dessas áreas tem subvertido o caráter público desses bens e fortalecido a imagem das cidades como mercadorias vendáveis no mercado global.AbstractThis  paper  aims  to  contribute  to  the  reflection  of  the socio-spatial processes  involved in the current projects of urban refuntionalization, enhancing  the strategies for preservation of  the built historical patrimony and the reintegration of  the abandoned urban areas, mainly  in the histoncal centers consolidated by  industries. The political and business management  have subverted  the public character of these goods, and strength the image of cities as goods to be sold in the global market.
Os períodos do espaço

Os limites traçados na superfície da Terra pelas sociedades constituem objetos históricos. Não há nenhuma dúvida disso com relação às fronteiras, mas o mesmo também ocorre com os pequenos ou grandes conjuntos submetidos à ação da natureza, como os continentes. De modo reciproco, os recortes temporais, os periodos, que colocam ordem nos passados, só têm pertinência num determinado espaço delimitado da sociedade. Para qualquer tipo de periodização é necessário dizer a que local ela se aplica, da mesma forma que para toda delimitação de uma área também é necessário precisar quais são seus marcos cronológicos. É impossível falar de uma era sem área -e vice-versa.AbstractThe limits drawn on the surface ofthe Earth by societies are territorial objects. No doubt for frontiers, but it is the same for big or small unities built by nature such as the continents. On the other hand, the temporal stnictures, the periods which set an order in the pasts, are judicious only for a delimited society. To define a period, we must say at what place it applies to, as we must also speciQ what are the chronological limits of an area. No era without area - and vice versa.
De saberes e de territórios: diversidade e emancipação a partir da experiência Latino-Americano
Authors: Porto-Gonçalves Carlos Walter
Published: October 2018

O artigo problematiza a relação entre saberes e territórios pondo em questão a idéia eurocêntrica de conhecimento universal. Com isso o autor pretende: (1) retirar o caráter unidirecional que os europeus impuseram a essa ideia (eurocentrismo) e (2) afirmarque as diferentes matrizes de racionalidade constituidas a partir de diferentes lugares são passíveis de serem universalizadas, o que nos obriga a considerar os processos por meio dos quais os conhecimentos podem dialogar, se relacionar. Enfim, o que se visa é um diálogo de saberes que supere a colonialidade do saber e do poder.AbstractThis article renders problematic the relation between knowledges and territories, by putting in question the eurocentric idea of universal knowledge. In so doing the author intends: (1) remove the unidirectional character Europeans have impose to this idea (eurocentrism), and (2) arguing that different matrixes of rationality constituted through distinct places are liable to be universalized. This can obligate.us to consider processes through which knowledges can dialogue, construct relationships. Finally, it aims a dialogue of knowledges to overcome the coloniality of knowledge and power.
Campesinidade e território Quilombola no norte do Espírito Santo
Authors: Batista Ferreira Simone Raquel
Published: October 2018

Este trabalho busca analisar as comunidades negras rurais do norte do Espírito Santo a partir das características e práticas camponesas na reapropriação de seu território. Estas práticas de territorialidade retomam antigas origens e saberes, e vêm sendo fortalecidaspela incorporação do direito étnico ao território, ora afirmado pelo Estado por meio de seureconhecimento como "comunidades remanescentes de quilombos". Abstract This work aims to analyse the rural black communities of north Espírito Santo state, in Brazil, from the peasants characteristics and practices in the reappropriation of their territov. These practices of territoriality retake old origins and wisdoms, and they are being stressed through the incorporation of ethnic rights to tenitory, at the same time legitimated by the State through its recognition as "communities remaining of quilombos".

Mercados imobiliários em áreas pobres: singularidades, particularidades e universalidades
Authors: Lacerda Norma
Published: October 2018

As reflexões sobre o mercado imobiliário em áreas pobres induziram questionarmos se as suas normas gerais de funcionamento não estariam obscurecendo as particularidades e as singularidades observadas em cada um dos submercados, especialmente no de locação, em que as relações interpessoais perduram durante todo o período do aluguel. Frente a essa indagação, este texto tem como objetivo verificar a hipótese de que o mercado imobiliário de locação em áreas pobres funciona a partir de normas gerais, mas também de normas dependentes das situações nas quais eles se inserem. O teste dessa hipótese levou a refletir-se sobre a possibilidade de uma leitura econométrica dos preços realizados, bem como sobre a validade de políticas de regularização fundiária de caráter universal.
Bacias hidrográficas interminentes sazonais e potencialidades hidroambientais no nordeste setentrional brasileiro
Authors: Nascimento Flávio Rodrigues do
Published: October 2018

As bacias hidrográficas no Trópico semiárido brasileiro, em grande maioria, drenam terras secas (áridas, semiáridas e subúmidas secas), formando características fisiográficas bem particulares, com dinâmica hidrológica que depende da renovação espaço-temporal das chuvas, a partir basicamente do escoamento superficial, em determinados períodos do ano. Este regime sazonal (intra ou extra-anual) influencia os potenciais hidroambientais da região Nordeste do Brasil. Destacar a influencia das renovações das chuvas no regime hidrológico de bacias intermitentes sazonais dessa região é o objetivo deste artigo. Para tanto, foram consideras as bacias hidrográficas como referencial de análise e planejamento para discussões a cerca de suas potencialidades e limitações hidroambientais, frente aos problemas do Trópico semiárido. Temas como contexto geoambiental e gestão de bacias hidrográficas, Dinâmica hidrológica e condições hidrogeológicas foram tratados no artigo.

Considerações sobre a expansão da indústria de papel e celulose no Brasil a partir do caso da Suzano Papel e Celulose
Authors: Marques Marta Inez Medeiros
Published: October 2018

Este artigo aborda a expansão da indústria de papel e celulose no Brasil observada nas últimas décadas, com especial atenção para: o processo de concentração e centralização do capital que afeta as empresas do setor no período; o papel desempenhado pelo Estado neste processo; e o seu impacto no campo. Para melhor fundamentar a análise e situá-la no nível local, são apresentados aspectos da trajetória recente da Suzano Papel e Celulose e de suas principais estratégias de territorialização. Constatou-se o significativo impacto da mundialização da economia na indústria de papel e celulose, o crescimento da produção nacional - com destaque para a celulose, que triplicou o volume produzido nos últmos 20 anos -, a consolidação de empresas mundiais e a expansão do plantio de eucalipto e do mercado “florestal” em diferentes regiões do país. O estudo baseou-se em levantamento de material documental, cartográfico e em pesquisa direta, além da análise de dados estatísticos oficiais e de entidades de representação do setor de produção de madeira, papel e celulose.
Organizaciones interprofesionales e innovación agrícola: entre lógicas globales y territoriales. El rol de ACSOJA, ASAGIR y PROARROZ en Argentina
Authors: Locher Valentina , Guibert Martine
Published: October 2018

O artigo analisa o papel das organizações inter profissionais (OIP) nos processos de inovação agrícola. Estes jogadores, relativamente recentes na Argentina, são caracterizados por uma integração vertical dos atores da cadeia agroindustrial e eles têm a particularidade de uma manifesta vocação tecnológica. Mostramos, a partir de uma abordagem comparativa, como esses atores assumem diferentes papéis, dependendo das condições que caracterizam a cadeia que eles representam. O referencial teórico combina abordagens institucionalistas sobre diferentes maneiras de coordenar os processos de inovação com abordagens críticas que permitem dar conta de lógicas globais e territoriais que cruzam os processos de inovação das cadeias.Três casos são analisados: ACSOJA (OIP da cadeia da soja), ASAGIR (OIP da cadeia do girassol) e PROARROZ (OIP da cadeia do arroz). Utilizam-se documentos institucionais de organizações e entrevistas conduzidas pessoalmente com atores como fontes de informação.
COMPARTIMENTAÇÃO GEOAMBIENTAL COMO ETAPA METODOLÓGICA PARA DETECÇÃO E PROSPECÇÃO DE ÁREAS SUSCEPTÍVEIS À DESERTIFICAÇÃO (ASDS)
Authors: Rodrigues do Nascimento Flávio , Felipe Farias Juliana
Published: October 2018

A desertificação é resultante da conjugação de fatores climáticos somados às consequências de atividades humanas impactantes, desenvolvidas em ambientes áridos e semiáridos. As áreas desertificadas, com destaque para o Nordeste do Brasil, estão em expansão, comprometendo os recursos naturais em qualidade e quantidade, e o exercício de algumas atividades econômicas. Com base nessa discussão, é necessária a elaboração e a aplicação de medidas preventivas e corretivas para conter o avanço e o estabelecimento da desertificação. A partir dessa necessidade, o artigo apresentado traz uma proposta metodológica para a detecção e a prospecção de áreas susceptíveis a degradação, tendo como recorte de análise a bacia hidrográfica do Médio Jaguaribe, situada no estado do Ceará. Foi realizada a sua compartimentação, destacando os principais aspectos como: condicionantes ambientais e de uso/ocupação, espacializados em mapas temáticos. Os aspectos metodológicos foram ressaltados de maneira detalhada, para demonstrar que a proposta pode ser aplicada em outras áreas/setores. Como principais resultados foi possível destacar que a bacia teste está susceptível a desertificação, principalmente nas áreas dos sertões semiáridos, e que a metodologia proposta é eficaz na detecção de áreas susceptíveis a degradação, podendo ser utilizada em outros setores com adaptações realizadas ao objeto investigado.
