Authors: Queiroz Luziana Nunes , Morais Ione Rodrigues , Aloufa Magdi Ahmed
Published: February 2019

Este artigo problematiza a relação entre expansão urbana e vulnerabilidade socioeconômica, tendo como referência a Cidade de Caicó (Brasil) e como recorte temporal a década de 1980 aos dias atuais. Nessa investida, analisou-se a expansão urbana de Caicó, por fases de ocorrência, considerando as variáveis população, economia e espacialização citadina e calculou-se os índices e níveis de vulnerabilidade socioeconômica da cidade, por zonas geográficas e bairros, a partir dos quais foi produzida cartografia relativa a essa temática. Metodologicamente, recorreu-se a pesquisa bibliográfica e documental. Assim, a cartografia da vulnerabilidade socioeconômica de Caicó, por zonas geográficas e bairros, revela que os índices e níveis relativos a este fenômeno não apresentam grandes variações, situando-se entre médio e muito baixo; todavia é na Zona Oeste é a que apresenta maior vulnerabilidade econômica, sendo o Bairro João Paulo II o que detém o mais elevado índice na cidade. Outrossim, também se constata que, embora o IVSB médio tenha sido registrado em bairros de formação antiga, sua ocorrência se mostra mais contundente entre os bairros de formação recente. Nesse sentido, é possível inferir que, no caso da Cidade de Caicó, a vulnerabilidade socioeconômica está associada ao processo de expansão urbana, visto que este fenômeno se torna mais presente em bairros de formação recente, em geral situados na periferia das cidades, onde se concentram populações de menor poder aquisitivo e as políticas públicas são mais negligenciadas.

As áreas naturais urbanas proveem benefícios significativos para o bem-estar humano. Quando a importância dessas áreas é em grande parte reconhecida pelo conhecimento científico, incentivos legais como as Reservas Particulares de Patrimônio Natural Municipal (RPPNM) são uma prova prática de uma tendência de medidas para conservar estes valores. O presente artigo é uma revisão bibliográfica que explora a documentação de seis temas relacionados a estes benefícios considerados emergentes nas políticas públicas urbanas. Os resultados desta análise apontam o reconhecimento geral dos benefícios para o bem-estar humano mediante índices, mas também deixa clara uma necessidade da consideração dos benefícios no planejamento de cidades resilientes e mais biodiversas.

Introduction. This paper discusses the role of self-relevant information in individuals’ representations of the self. Self-relevant information is defined here as a type of social information that contains such data about an individual as other people’s opinions, judgements, and attitudes about that person. Critical assessment of the existing knowledge on the relationship between self-relevant information and individuals’ representations of the self shows its insufficiency, especially concerning Russian samples. This paper: (a) considers various concepts of individuals’ perception of self-relevant information, (b) focuses on the known properties of self-relevant information, and (c) describes the procedure and results of an empirical study of the relationship between self-relevant information and individuals’ representations of the self.
Methods. The authors undertook a socio-psychological experiment that employed standardized self-reports and interviews as the means for data collection. Content analysis and repeated measures ANOVA were the data processing methods. The sample consisted of 129 individual participants with a mean age of 19.3 years, 49 % of whom were men.
Results. The respondents perceived social information as self-relevant if it contained a) direct or indirect reference to them; b) information important for their actions and meeting their needs; and c) references to social objects associated with them. The study showed that self-relevant information affects individuals’ self-appraisal and the accuracy of their representations of the self. Negative self-relevant information encourages individuals to seek new social information and to verify it by social comparison.
Discussion. This study, carried out on the Russian sample, enriches our knowledge of individuals’ perception of self-relevant information and our understanding of how self-relevant information may lead to distorting individuals’ representations of the self. The findings offer some criteria for distinguishing self-relevant information from the irrelevant one. The results can be used to further study social identity transformations among participants of Internet communities and to assess threats of online communications in different age groups.

Published: February 2019

Introduction. This paper examines professionally important qualities of thermal power plants operational employees with various levels of professionalism when solving professional tasks in standard and emergency situations.
Methods. The sample size was 134 operational employees, 123 of whom were men and 11 – women; the mean age was 37 years. The level of professionalism was determined by expert assessments of their professional knowledge, skills, abilities, and problem-solving performance – qualities that the authors deemed to be important for ensuring high work performance. The study used: (a) the Prognoz technique for examination of neuro-mental stability; (b) the questionnaire for measuring the Level of Subjective Control (LSC) by Golynkina, Bazhin, and Etkind; (c) the test questionnaire for Studying Volitional Self-Regulation by Eidman and Zver'kov; (d) the Wonderlic Personnel Test (WPT) in Buzin’s modification; (e) the Spielberg–Hanin test; and (f) and the Kirton Adaptation-Innovation Inventory (KAI). Statistical data analyses included the t-test for independent samples, the Kruskal-Wallis H test, analysis of contingency tables, and factor analysis.
Results and Discussion. The results of expert assessment enabled authors to distinguish among three groups of specialists with different levels of professionalism; these were ‘pre-professionals’, ‘professionals’, and ‘super-professionals’. Super-professionals demonstrate high effectiveness, high level of professional knowledge, abilities, and skills, good and satisfactory levels of neuro-mental stability, increased indices of responsibility in various activities, volitional self-regulation, persistence, intellectual capacities, innovative cognitive style, and low level of personal and situational anxiety. Factor analysis revealed subsystems of professionally important qualities in the three groups. Responsibility, volitional qualities, and cognitive styles undergo qualitative changes in the process of the professionalism development. At a high level of professionalism, the qualities of responsibility, volitional qualities, and innovative cognitive style provide operational employees with professional and personal reliability and help them cope with anxiety in stressful situations.

Introduction. This paper (a) presents the study of psychological differences in manifestations of aggressive attitudes and personal characteristics among representatives of various ethnic groups living in South Russia and (b) concentrates on genetic differences in the COMT Val158Met polymorphism within the study sample. This is the first study that (a) has assessed manifestations of aggressive attitudes and personal characteristics in healthy representatives of various ethnic groups with different COMT genotypes and (b) has offered normative data for the Wagner Hand Test obtained from an investigation in a sample of South Russian individual participants.
Methods. The study used the following techniques: (a) the Spielberger–Hanin anxiety test, (b) the questionnaire of formal-dynamic characteristics of personality by Rusalov, and (c) the Wagner Hand Test (in Kurbatova’s modification). Genetic analysis included the method for DNA extraction from buccal epithelial cells and the polymerase chain reaction (PCR) method. The psychological study involved university students (n = 163; mean age, 18.9 years); the psychogenetic study involved residents of Crimea (n = 76; 57 women and 19 men).
Results. The representatives of Russian and Tatar ethnic groups with the Met/Met COMT genotype had significantly higher total scores of aggression and direction, higher level of trait anxiety, and low motor ergicity. Tatar girls from the Val/Val COMT genotype group had high scores in the exhibitionism scale. The Val/Met COMT genotype in Russian girls was associated with manifestations of tension (anxiety) and ‘pathology’ as a total index of ‘personal maladjustment’ and the ‘tendency to escape from reality’.
Discussion. The obtained results can be applied to the practice of individualized socio-pedagogical impacts on representatives of various ethnic groups with the genotypes associated with maladaptive personality traits.
The Role of MAPK's Signaling in Mediating ApoE4-Driven Pathology In Vivo
Authors: Salomon-Zimri Shiran , Koren Amit , Angel Ariel , Ben-Zur Tali , Offen Daniel , Michaelson Daniel M.
Published: February 2019

Background:

Alzheimer's Disease (AD) is associated with impairments in key brain Mitogen-
Activated Protein Kinase (MAPK) signaling cascades including the p38, c-Jun N-terminal kinase
(JNK), ERK and Akt pathways. Apolipoprotein E4 (ApoE4) is the most prevalent genetic risk factor of
AD.

Objectives:

To investigate the extent to which the MAPK signaling pathway plays a role in mediating
the pathological effects of apoE4 and can be reversed by experimental manipulations.
Methods: Measurements of total level and activation of MAPK signaling pathway factors, obtained utilizing
immunoblot assay of hippocampal tissues from naïve and viral-treated apoE3 and apoE4 targeted
replacement mice.

Methods:

Measurements of total level and activation of MAPK signaling pathway factors, obtained utilizing
immunoblot assay of hippocampal tissues from naïve and viral-treated apoE3 and apoE4 targeted
replacement mice.

Results:

ApoE4 mice showed robust activation of the stress related p38 and JNK pathways and a corresponding
decrease in Akt activity, which is coupled to activation of GSK3β and tau hyperphosphorylation.
There was no effect on the ERK pathway. We have previously shown that the apoE4-
related pathology, namely; accumulation of Aβ, hyper-phosphorylated tau, synaptic impairments and
decreased VEGF levels can be reversed by up-regulation of VEGF level utilizing a VEGF-expressing
adeno-associated virus. Utilizing this approach, we assessed the extent to which the AD-hallmark and
synaptic pathologies of apoE4 are related to the corresponding MAPK signaling effects. This revealed
that the reversal of the apoE4-driven pathology via VEGF treatment was associated with a reversal of
the p38 and Akt related effects.

Conclusion:

Taken together, these results suggest that the p38 and Akt pathways play a role in mediating
the AD-related pathological effects of apoE4 in the hippocampus.

Published: February 2019

Objectives: There is a body of evidence that neurodegenerative disease entities are directly
correlated with the perturbations on the molecular level. Hence, the ER stress-mediated Unfolded Protein
Response (UPR) is activated resulting in PERK-dependent phosphorylation of the Eukaryotic initiation
factor 2 (eIF2α). Thus, the levels of ATF4 and CHOP proteins are significantly increased, which
subsequently switches the pro-adaptive branch of the UPR into the pro-apoptotic directly leading to neuronal
loss and initiation of the neurodegenerative process. The aim of the presented study was the
evaluation of the biological activity of highly specific, small-molecule inhibitors of the PERKdependent
UPR signaling pathway.

Methods:

The study was conducted on rat astrocytic DI TNC1 cell line. The level of p-eIF2α was measured
by Western blot technique, the cytotoxicity of the investigated compound was assessed by the MTT
assay and using the FITC-conjugated Annexin V (Annexin V-FITC) to indicate apoptosis and propidium
iodide (PI) to indicate necrosis. The effect of tested compound on cell cycle progression was measured
by flow cytometry, where the PI-labelled nuclei were analysed for DNA content.

Results:

As a result one of the investigated compound LDN-0060609 triggers a significant inhibition of
the eIF2α phosphorylation in DI TNC1 cell line. Moreover, we showed that compound LDN-0060609 is
non-cytotoxic and has no effect on cell cycle progression.

Conclusion:

In conclusion, LDN-0060609 may constitute a novel, targeted treatment approach against
neurodegenerative diseases, including Alzheimer’s disease (AD), where pathogenesis and progression
are closely associated with the overactivation of the PERK-dependent UPR signaling pathway.
Distinctive Effects of Aerobic and Resistance Exercise Modes on Neurocognitive and Biochemical Changes in Individuals with Mild Cognitive Impairment
Authors: Tsai Chia-Liang , Pai Ming-Chyi , Ukropec Jozef , Ukropcová Barbara
Published: February 2019

Background:

Decreased levels of the neuroprotective growth factors, low-grade inflammation, and reduced neurocognitive functions during aging are associated with neurodegenerative diseases, such as Alzheimer’s disease. Physical exercise modifies these disadvantageous phenomena while a sedentary lifestyle promotes them.

Purpose:

The purposes of the present study included investigating whether both aerobic and resistance exercise produce divergent effects on the neuroprotective growth factors, inflammatory cytokines, and neurocognitive performance, and further exploring whether changes in the levels of these molecular biomarkers are associated with alterations in neurocognitive performance.

Methods:

Fifty-five older adults with amnestic MCI (aMCI) were recruited and randomly assigned to an aerobic exercise (AE) group, a resistance exercise (RE) group, or a control group. The assessment included neurocognitive measures [e.g., behavior and event-related potential (ERP)] during a task-switching paradigm, as well as circulating neuroprotective growth factors (e.g., BDNF, IGF-1, VEGF, and FGF-2) and inflammatory cytokine (e.g., TNF-α, IL-1β, IL-6, IL-8, and IL-15) levels at baseline and after either a 16-week aerobic or resistance exercise intervention program or a control period.

Results:

Aerobic and resistance exercise could effectively partially facilitate neurocognitive performance [e.g., accuracy rates (ARs), reaction times during the heterogeneous condition, global switching cost, and ERP P3 amplitude] when the participants performed the task switching paradigm although the ERP P2 components and P3 latency could not be changed. In terms of the circulating molecular biomarkers, the 16-week exercise interventions did not change some parameters (e.g., leptin, VEGF, FGF-2, IL-1β, IL-6, and IL-8). However, the peripheral serum BDNF level was significantly increased, and the levels of insulin, TNF-α, and IL-15 levels were significantly decreased in the AE group, whereas the RE group showed significantly increased IGF-1 levels and decreased IL-15 levels. The relationships between the changes in neurocognitive performance (AR and P3 amplitudes) and the changes in the levels of neurotrophins (BDNF and IGF-1)/inflammatory cytokines (TNF-α) only approached significance.

Conclusion:

These findings suggested that in older adults with aMCI, not only aerobic but also resistance exercise is effective with regard to increasing neurotrophins, reducing some inflammatory cytokines, and facilitating neurocognitive performance. However, the aerobic and resistance exercise modes likely employed divergent molecular mechanisms on neurocognitive facilitation.

Published: February 2019

Far-infrared ray (FIR) is an electromagnetic wave that produces various health benefits
against pathophysiological conditions, such as diabetes mellitus, renocardiovascular disorders,
stress, and depression etc. However, the therapeutic application on the FIR-mediated protective
potentials remains to be further extended. To achieve better understanding on FIR-mediated therapeutic
potentials, we summarized additional findings in the present study that exposure to FIR ameliorates
stressful condition, memory impairments, drug dependence, and mitochondrial dysfunction
in the central nervous system. In this review, we underlined that FIR requires modulations of janus
kinase 2 / signal transducer and activator of transcription 3 (JAK2/STAT3), nuclear factor E2-
related factor 2 (Nrf-2), muscarinic M1 acetylcholine receptor (M1 mAChR), dopamine D1 receptor,
protein kinase C δ gene, and glutathione peroxidase-1 gene for exerting the protective potentials
in response to neuropsychotoxic conditions.

Published: February 2019

Objective: Metastasis phenotype is considered as the main challenge in colon cancer therapeutic
methods. Furthermore, the side effects of conventional colorectal cancer treatment methods have attracted a lot
of attention into natural ingredients. The aim of the study was to assess the molecular mechanism of verbascoside
as natural bio-compound in human HT29 colon cancer cells.

Methods:

HT29 cells were cultured in RPMI-1640 medium containing 10% FBS and 1% penicillin/
streptomycin at 37°C and 5% CO2. HT-29 cells were treated with different concentrations of verbascoside
(10, 20, 30, 40, 50, 70, 100 µg/ml) for 24 hours, then MTT assay was used to calculate 50% inhibitory concentration.
The migration of the colon cancer cells was evaluated by scratch assay. To evaluate involved antiproliferative
mechanism, Rac-1 (Ras-related C3 botulinum toxin substrate 1) and HIF-1α (hypoxia-inducible
factor-1α) related gene expression were evaluated by Real Time PCR.

Results:

The results showed that verbascoside inhibited HT29 colon cancer cell proliferation dose-dependently
and IC50 was evaluated as 50 μg/ml (***P<0.001). The results of wound healing assay demonstrated verbascoside
decreased cell migration in a dose dependent manner. In the IC50 treated HT29 cells metastatic progression
was significantly suppressed as **P<0.01. The results of Real Time PCR showed an attenuating effect of verbascoside
on Rac-1, Zeb-1 (zinc finger E-box binding homeobox 1), Arp2 (Actin-Related Proteins), Pak1 (p21
(RAC1) activated kinase 1), VEGF (Vascular endothelial growth factor) and HIF-1α as Epithelial-Mesenchymal
Transition markers. The down regulation of mRNA levels was Rac-1= 15.38, HIF-1 α = 16.66, Pak-1, Arp-2=
6.25, VEGF=24.39, Zeb-1=35.71 in HT29 cells treated with IC50 concentration of verbascoside.

Conclusion:

Colorectal cancer cells induce Rac-1 and HIF-1α overexpression which plays an important role in
the activation and progression of cell motility, angiogenesis and metastasis. Overall results showed that verbascoside
elucidated significant anti-metastatic and anti-invasion activities through suppression of Rac-1, HIF-1α, and
Zeb-1 signaling pathway and it may be a suitable candidate to overwhelm colon cancer metastatic phenotype.
Immunohistochemical Expression of Melatonin Receptor MT1 and Glucose Transporter GLUT1 in Human Breast Cancer
Authors: de Castro Tialfi B. , Mota André L. , Bordin-Junior Newton A. , Neto Dalisio S. , Zuccari Debora A.P.C.
Published: February 2019

Background:

Breast cancer is a heterogeneous disease and is the leading cause of cancer-related
deaths among women. Even after diagnosis, the prognosis cannot be concluded since patients can develop resistance
to therapy, which favors tumor growth, invasion and metastasis. In recent years, research has focused on
identifying significant markers that can be used to determine the prognosis. Melatonin can act through G protein–
coupled MT1 receptor, which controls selected protein kinases, influences the levels of transcription factor
phosphorylation, specific genes expression, proliferation, angiogenesis, cell differentiation, migration, and indirectly
controls the transport of glucose in cancer cells. It is known that glucose enters the cells by glucose transporters,
such as GLUT1 which shows wide tissue distribution and appears to be altered in human breast carcinoma.
High GLUT1 expression is associated with increased malignant potential, invasiveness and poor prognosis
in some cancers including breast cancer.

Objective:

The aim of this study was to evaluate the expression of MT1 receptor and GLUT1 in breast tumors
and correlate with molecular subtypes and prognostic characteristics.

Method:

Protein expression was performed by an immunohistochemical procedure with specific antibodies and
positive and negative controls.

Results:

We found that MT1 high expression was associated with good prognosis subtype (Luminal A), while
GLUT1 high expression was related to poor prognosis subtype (triple-negative). In addition, we found high
expression of MT1 in ER+ and the inverse in GLUT1 expression. GLUT1 is also highly expressed in tumor
≥20mm.

Conclusion:

These results indicate MT1 and GLUT1 as potential targets for breast cancer subtypes and prognosis.
Development of Ductile Truss System Using Double Small Buckling-Restrained Braces: Analytical Study
Authors: Sugihardjo Hidajat , Lesmana Yudha , Prasetya Dwi
Published: February 2019

Introdution:

This paper proposed a Small Buckling-Restrained Brace (SBRB) for the ductile truss moment frames and is called here as the Double Braced Truss Moment Frames (DB-TMF). The braces are located at the edge of the truss girder and are only placed around the building perimeter. The braces work in pair as a weak element (structural fuses) and is expected to effectively absorb the seismic energy. The proposed DB-TMF system is an extended development of the Knee Braced Truss Moment Frames (KB-TMF). The DB-TMF system is expected to carry the whole seismic loads, while the rest of the frame is designed to carry only the gravity loads.

Methods:

To study the performance of the proposed DB-TMF system, non-linear finite element analysis was carried out using the DRAIN-2DX package. From the analysis with various time history records, it was found that the drift ratio of the DB-TMF system is lower than the allowed story drift. The roof-top displacement shows an asymptotic behavior. The shape of the hysteresis curve tends to have a pinching shape. However, the cumulative ductility of the proposed system satisfies the requirements as a hysteretic structure. In the event of an earthquake, only the SBRB and the chords adjacent to the column element are damaged while the rest of the structural elements remain elastic which is expected.

Results and Conclusion:

Based on the performance evaluation of the DB-TMF system, the DB-TMF system is suitable for moderate seismic region and has smaller dimension steel sections compared to the KB-TMF system.
Nanotoxicity Assessment: A Necessity
Authors: Joshi Monica , Prabhakar Bala
Published: February 2019

Rapid growth of nanotechnology in various fields like medicine, diagnostics, biotechnology,
electronics has gifted the world with products having extraordinary benefits. With increasing
use of nanotechnology based products, there is a growing concern about toxicity associated with
nanoparticles. Nano-size attributes unique properties to the material due to the increased surface
area. But toxic effects associated with nanoparticles are also pronounced. Therefore, research in
the field of nanotoxicology is of great importance. Some critical properties of nanoparticles such
as chemical composition, size, shape, surface properties, purity are determinants of nanotoxicity.
Thus, meticulous characterization of nanoparticles prior to toxicity assessment helps in reducing
the toxicity by careful designing of nanoparticles. In vitro assessment of nanotoxicity involves testing
on cultured cells whereas in vivo testing involves use of animal models like mice, rats, aquatic
frogs etc. Use of predictive models like Zebrafish, Drosophila melanogaster for nanotoxicity research
is increased in last few decades. Advanced methods for nanotoxicity assessment involve the
use of electrochemical methods which can also give insights about mechanism of nanotoxicity. As
the literature in this field is dispersed, this review collates various approaches to give a scheme for
nanotoxicity evaluation right from the characterization to toxicity assessment.
Comparing Self-Monitoring Strategies for Weight Loss in a Smartphone App: Randomized Controlled Trial (Preprint)
Authors: Patel Michele L , Hopkins Christina M , Brooks Taylor L , Bennett Gary G
Published: February 2019

BACKGROUND

Self-monitoring of dietary intake is a valuable component of behavioral weight loss treatment; however, it declines quickly, thereby resulting in suboptimal treatment outcomes.

OBJECTIVE

This study aimed to examine a novel behavioral weight loss intervention that aims to attenuate the decline in dietary self-monitoring engagement.

METHODS

GoalTracker was an automated randomized controlled trial. Participants were adults with overweight or obesity (n=105; aged 21-65 years; body mass index, BMI, 25-45 kg/m2) and were randomized to a 12-week stand-alone weight loss intervention using the MyFitnessPal smartphone app for daily self-monitoring of either (1) both weight and diet, with weekly lessons, action plans, and feedback (Simultaneous); (2) weight through week 4, then added diet, with the same behavioral components (Sequential); or (3) only diet (App-Only). All groups received a goal to lose 5% of initial weight by 12 weeks, a tailored calorie goal, and automated in-app reminders. Participants were recruited via online and offline methods. Weight was collected in-person at baseline, 1 month, and 3 months using calibrated scales and via self-report at 6 months. We retrieved objective self-monitoring engagement data from MyFitnessPal using an application programming interface. Engagement was defined as the number of days per week in which tracking occurred, with diet entries counted if ≥800 kcal per day. Other assessment data were collected in-person via online self-report questionnaires.

RESULTS

At baseline, participants (84/100 female) had a mean age (SD) of 42.7 (11.7) years and a BMI of 31.9 (SD 4.5) kg/m2. One-third (33/100) were from racial or ethnic minority groups. During the trial, 5 participants became ineligible. Of the remaining 100 participants, 84% (84/100) and 76% (76/100) completed the 1-month and 3-month visits, respectively. In intent-to-treat analyses, there was no difference in weight change at 3 months between the Sequential arm (mean −2.7 kg, 95% CI −3.9 to −1.5) and either the App-Only arm (−2.4 kg, −3.7 to −1.2; P=.78) or the Simultaneous arm (−2.8 kg, −4.0 to −1.5; P=.72). The median number of days of self-monitoring diet per week was 1.9 (interquartile range [IQR] 0.3-5.5) in Sequential (once began), 5.3 (IQR 1.8-6.7) in Simultaneous, and 2.9 (IQR 1.2-5.2) in App-Only. Weight was tracked 4.8 (IQR 1.9-6.3) days per week in Sequential and 5.1 (IQR 1.8-6.3) days per week in Simultaneous. Engagement in neither diet nor weight tracking differed between arms.

CONCLUSIONS

Regardless of the order in which diet is tracked, using tailored goals and a commercial mobile app can produce clinically significant weight loss. Stand-alone digital health treatments may be a viable option for those looking for a lower intensity approach.

Overcoming Barriers to Mobilizing Collective Intelligence in Research: Qualitative Study of Researchers With Experience of Collective Intelligence (Preprint)
Authors: Nguyen Van Thu , Young Bridget , Ravaud Philippe , Naidoo Nivantha , Benchoufi Mehdi , Boutron Isabelle
Published: February 2019

BACKGROUND

Innovative ways of planning and conducting research have emerged recently, based on the concept of collective intelligence. Collective intelligence is defined as shared intelligence emerging when people are mobilized within or outside an organization to work on a specific task that could result in more innovative outcomes than those when individuals work alone. Crowdsourcing is defined as “the act of taking a job traditionally performed by a designated agent and outsourcing it to an undefined, generally large group of people in the form of an open call.”

OBJECTIVE

This qualitative study aimed to identify the barriers to mobilizing collective intelligence and ways to overcome these barriers and provide good practice advice for planning and conducting collective intelligence projects across different research disciplines.

METHODS

We conducted a multinational online open-ended question survey and semistructured audio-recorded interviews with a purposive sample of researchers who had experience in running collective intelligence projects. The questionnaires had an interactive component, enabling respondents to rate and comment on the advice of their fellow respondents. Data were analyzed thematically, drawing on the framework method.

RESULTS

A total of 82 respondents from various research fields participated in the survey (n=65) or interview (n=17). The main barriers identified were the lack of evidence-based guidelines for implementing collective intelligence, complexity in recruiting and engaging the community, and difficulties in disseminating the results of collective intelligence projects. We drew on respondents’ experience to provide tips and good practice advice for governance, planning, and conducting collective intelligence projects. Respondents particularly suggested establishing a diverse coordination team to plan and manage collective intelligence projects and setting up common rules of governance for participants in projects. In project planning, respondents provided advice on identifying research problems that could be answered by collective intelligence and identifying communities of participants. They shared tips on preparing the task and interface and organizing communication activities to recruit and engage participants.

CONCLUSIONS

Mobilizing collective intelligence through crowdsourcing is an innovative method to increase research efficiency, although there are several barriers to its implementation. We present good practice advice from researchers with experience of collective intelligence across different disciplines to overcome barriers to mobilizing collective intelligence.

Effect of Urbanization on Banking Sector Development in Waemu Countries: Evidence from Panel Quantile Regression
Authors: Seraphin PRAO Yao
Published: February 2019

Urbanization is one of the most significant forces on the planet in the 21st century. In Africa, cities and their inhabitants are at the heart of development processes. Within the African continent, the level of West African urbanization is 41% in 2010 compared to 36% in 2000. According to projections, by 2030, 50% of Africans will live in cities. Urban demand could be an engine of industrial development because the level of urbanization is associated with many positive outcomes, such as technological innovation, economic progress, higher living standards. As a result, urbanization could positively influence banking development. This paper examines the impact of urbanization on financial sector development in a panel of 7 WAEMU countries. Contrary to previous studies that focus on mean effects, it uses quantile regression methodology to examine the effect of urbanization on financial development in those countries that share a common currency. The results point out that urbanization and economic openness is favourable to the financial development of WAEMU countries. The study urges governments to create the necessary conditions for successful urbanization so that it benefits financial development. Economic openness must also be promoted as it is conducive to the financial development of the WAEMU region.

Consideraciones y consecuencias metodológicas en torno a la globalización y la comunicación
Authors: Casas Pérez María De la Luz
Published: February 2019

Dentro de la crisis de los paradigmas, la globalización parece ser el nuevo constructo social que permite entender los fenómenos de organización social. Lo global y, por extensión, la globalización son categorías de análisis cuya base fundamental es económica pero que han venido utilizándose con referencia a distintas manifestaciones de lo social. Este artículo explora aquellas consideraciones metodológicas que deben ser tomadas en cuenta al utilizar la globalización como macrocategoría de trabajo y, por otro lado, las consecuencias de esta última en relación con fenómenos observables específicamente en el campo de la comunicación social. Por otra parte, analiza las nuevas formas de relación que se producen en condiciones de globalidad y en particular el papel de los medios de comunicación en la construcción de las identidades sociales globales, nacionales y culturales.

Antecedentes teóricos de la etnometodología y el interaccionismo simbólico
Authors: Rodríguez Dorantes Cecilia
Published: February 2019

En este artículo teórico retrospectivo—producto de una investigación más amplia—, la autora se centra en el estudio y análisis de las potencialidades explicativas de la sociología de la vida cotidiana. En él se pretende ubicar los antecedentes de dos escuelas fundamentales en el estudio del mundo ordinario: la etnometodología y el interaccionismo simbólico. Para ello, la autora organiza su escrito en torno a tres apartados: en el primero se ubican la fenomenología y la filosofía del lenguaje ordinario como las dos grandes vertientes teóricas cuya convergencia dará origen a la etnometodología. En el segundo, se presentan los antecedentes teóricos del interaccionismo simbólico y sus principales postulados. Finalmente, en el tercer apartado se presentan los estudios de la conversación como resultado de las mutuas influencias entre la etnometodología y el interaccionismo simbólico.

La política y el periodismo en el nuevo espacio público
Authors: Ortega Félix
Published: February 2019

El artículo aborda la relevancia del espacio público en la dinámica política actual y del uso que de él hacen los medios masivos de comunicación y la clase política. En un inicio, Félix Ortega nos habla del proceso histórico del espacio público como el medio de relación dialéctica entre las necesidades de la sociedad —lo privado— y la política. Ortega resalta las profundas transformaciones sociopolíticas del Estado moderno, en que el espacio público abandona su papel como mediador entre lo privado y la política, y del Estado democrático, en el cual también se genera un quiebre entre el espacio público y lo político, debido a los medios masivos de comunicación, que fungen como desarticuladores de la sociedad, y a la generación de la imposibilidad de gestión de la política democrática, consecuencia de la saturación de obligaciones dentro del proceso de globalización. En la segunda parte del artículo, el doctor Ortega hace énfasis en la forma en cómo el espacio público es absorbido por el llamado “cuarto poder”, sirviendo como mediador no sólo entre la política y lo social, sino incluso al interior de estos sectores. Aquí se destacan las pragmáticas relaciones de mutua influencia entre la clase política y los periodistas, como representantes de un grupo de interés, estableciendo así nuevas formas de relación social
La reelección parlamentaria inmediata: un reto en la agenda política de México
Authors: Béjar Algazi Luisa
Published: February 2019

El papel que se le asigna a la reelección inmediata de los legisladores en el proyecto de renovación institucional emprendido por México es motivo de hondas discrepancias entre los partidos políticos. Para unos, el fortalecimiento del Poder Legislativo necesariamente pasa por su reestablecimiento en la Constitución. Para otros, las enmiendas que deben realizarse deben ser de corte diverso. Ante este panorama, este escrito se pregunta qué hay detrás de esa figura, cuáles han sido las consecuencias de su prohibición para el país, y qué intereses se encuentran actualmente en juego en el fallo de los legisladores con relación al asunto.

Authors: Toussaint Florence
Published: February 2019

Este artículo elabora una reflexión teórica pertinente en torno al papel de los medios de comunicación en la participación política de los ciudadanos. A partir de una revisión de las principales teorías y tesis acerca de cómo los medios pueden llegar a persuadir al auditorio, de los límites y/o de las distorsiones en tal proceso y de cómo las elecciones se han convertido en un momento ideal para investigar el comportamiento de los sujetos frente a la televisión, este trabajo señala las directrices sobre las cuales se puede abordar el análisis teórico y empírico de este fenómeno.

Schmitt: el pensamiento filosófico de lo político
Authors: Jiménez Ramírez Alejandra
Published: February 2019

En este artículo, la autora retoma la reflexión filosófica de Carl Schmitt referente al concepto de lo político para repensar esta dimensión como espacio en constante y fluctuante construcción. Partiendo de esta premisa, en un primer apartado se realiza un ejercicio de analogía de la discusión del lugar de lo político en Schmitt con la del ser de Heidegger y la de los dioses de Nietzsche. En el segundo apartado se considera la tradición estructuralista de la antropología para hacer una reflexión del carácter mítico de la distinción amigo/enemigo que estructuran en Schmitt el concepto de lo político. El ensayo concluye con un tercer apartado que apela a lo político como instancia desterritorializada, en tanto lo político nos remite a lo simbólico, de ahí que el lugar de lo político sea incluso el no-lugar.
