Published: May 2022

Today, economic development and development are extremely important. With the increasing need for energy in both the world and Turkish economy, the importance of ensuring the sustainability of the energy resources used and the security of energy supply is also increasing. Implementation of a sustainable energy system; It includes important factors such as efficient energy use together with sufficient, economical, safe and environmentally compatible energy supply. Energy is one of the main factors to consider in discussions of sustainable development. The main dimensions of sustainability in energy production are environmental protection and the economically and socially sustainable supply of energy resources in a way that is reliable, sufficient and financially accessible in the long run. For this reason, it is important for Turkey to identify sustainable energy problems and determine the right energy policy. In this study, the determination of sustainable energy problems and the problems of determining the right energy security policy in manufacturing enterprises in Samsun province in Turkey were made with multi-criteria decision making methods. As a result of this research, the most ideal energy security policy was “Resource Sharing” in the selection created by using the degrees of sustainable energy related problems in manufacturing enterprises. On the other hand, the most ideal energy security alternatives were realized as Resource Sharing (A4)>> Source Distribution (A3)>> Resource Diversification (A1)>> Price Security (A2), respectively.

Authors: Cai Jianyu , Yu Zehui , He Junda , Li Jian
Published: May 2022

The Pd-Co-Ti catalyst was successfully prepared by the method of impregnation-precipitation-ball milling. The structure and redox properties of Pd-Co-Ti catalyst was investigated by N22 desorption, X-ray powder diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and H22-TPR. The results show that the Pd-Co-Ti catalyst has a large specific surface area and a rich pore structure, and there are Co33O44 and anatase TiO22 crystals in the catalyst. The synergistic effect of Pd and Co improves the redox ability of Pd-Co-Ti catalyst. The catalyst is used to treat CO in the flue gas of rolling mills. It runs for 168 hours at a space velocity of 30,000 cm33/(g⋅⋅h) and a temperature of 280∘∘C, and the CO removal rate is basically maintained at more than 90%. The ratio of inlet CO content and O22 content affects the catalyst CO removal efficiency. When the ratio is greater than 0.5, the CO removal efficiency has a downward trend. The results of this study are of great significance to the practical application of CO oxidation technology.

Published: May 2022

The objective of this work was to evaluate the soil physical attributes and their relationship to soybean productivity under no-tillage system. The study was conducted in a Oxisol, based on randomized blocks design, with the treatments: no-tillage for 10 years (0 tractor traffic) and five tractor-traffic intensities (2, 4, 6, 8, and 12 passes), with five repetitions. An increase of macroporosity up to 10% under soil bulk density ranging from 1.51 to 1.56 mg.m-3 and soil penetration resistance between 1.5 to 2.0 MPa, on the 0.00-0.10 m layer benefited the soybean productivity. The number of pods per plant, grain number per plant, stem diameter, and soybean productivity is higher in Oxisol, under intermediate compression. Soil bulk density and soil penetration resistance showed to be sensitive an indicators of soil physical quality, with more relation to soybean grain productivity.

Semi-analytical model for the analysis of a magnetically biased 1D subwavelength graphene-strip-grating
Authors: Ben Rhouma Maha , Guizal Brahim , Bonnet Pierre , Paladian Françoise , Edee Kofi
Published: May 2022

We propose a simple semi analytical model that allows to compute the transmittance and reflectance of a one dimensional subwavelength graphene strip grating under an external static magnetic field. In this model graphene is treated as an anisotropic layer with atomic thickness and a frequency dependent complex permittivity tensor. The model is based on an effective medium approach (EMA) and a rigorous phase correction. The scattering matrix approach is also used to take into account the different resonant phenomena occurring in the structure. The approach is validated against the Polynomial Modal Method (PMM) through numerical examples.
A mechanistic model of snakebite as a zoonosis: Envenoming incidence is driven by snake ecology, socioeconomics and its impacts on snakes

Published: May 2022

Snakebite is the only WHO-listed, not infectious neglected tropical disease (NTD), although its eco-epidemiology is similar to that of zoonotic infections: envenoming occurs after a vertebrate host contacts a human. Accordingly, snakebite risk represents the interaction between snake and human factors, but their quantification has been limited by data availability. Models of infectious disease transmission are instrumental for the mitigation of NTDs and zoonoses. Here, we represented snake-human interactions with disease transmission models to approximate geospatial estimates of snakebite incidence in Sri Lanka, a global hotspot. Snakebites and envenomings are described by the product of snake and human abundance, mirroring directly transmitted zoonoses. We found that human-snake contact rates vary according to land cover (surrogate of occupation and socioeconomic status), the impacts of humans and climate on snake abundance, and by snake species. Our findings show that modelling snakebite as zoonosis provides a mechanistic eco-epidemiological basis to understand snakebites, and the possible implications of global environmental and demographic change for the burden of snakebite.

Published: May 2022

The spread of African swine fever (ASF) in Eurasia has forced a return to the development of live vaccines based on naturally or experimentally attenuated strains of the virus including those resulting from genetic manipulations. This process includes evaluation of the immunomodulating properties of the vaccines. In this report we provide our assessment of two tests for immunobiological evaluation of a candidate live vaccine against ASF from the attenuated ASF virus (ASFV) strain KK-202: (i) investigation of the effect of the attenuated ASFV strain KK-202 on the protectiveness of the vaccine ASFV strain FK-32/135 and a vaccine against classical swine fever (CSF) from the strain LK-VNIIVViM; (ii) determination of the phagocytic activity of blood neutrophils in pigs inoculated with ASFV strains differing in virulence. A simultaneous or sequential inoculation of attenuated strain KK-202 (seroimmunotype II) and vaccine strain FK-32/135 (seroimmunotype IV) into pigs resulted in the loss of protection against the virulent strain France-32 (seroimmunotype IV). Following the simultaneous or sequential inoculations of the ASFV strain KK-202 and the CSF virus (CSFV) vaccine produced from the strain LK-VNIIVViM, the neutralizing antibody titers against the CSFV observed in the experimental groups (after vaccination and after the challenge infection with the virulent CSFV strain Shimen) were not different from those found in animals of the control group. The phagocytic activity of blood neutrophils was shown to increase from 30% in the norm to 50%–94% depending on the virulence of the ASFV strains inoculated into pigs. The results of this work demonstrate the ability of the attenuated ASFV strains to modulate the development of the cellular link of protective immunity without negative impact on the humoral immune response. The informative value of the described immunobiological tests in vivo and in vitro seems to be a more preferable alternative in comparison to the commonly used in vitro tests, which do not always correlate with the development of protection against ASF.

Published: May 2022

In the field of adolescent gambling prevention, there is a lack of intervention studies reporting and assessing training courses for the intervention providers. The present work fills this gap by realizing a dissemination study inside the PRIZE program aimed at modifying a set of cognitive protective factors and affective risk factors. The purpose of this work was twofold: To develop and evaluate a training course with the intervention providers (Study 1), and to assess the short- and long-term effects of the intervention itself (Study 2). The training course was delivered to 44 health professionals (32 females, Mage = 39.34 years). Results showed a significant increase of correct knowledge about gambling and a significant reduction of their susceptibility to probabilistic reasoning biases. Participants also actually learnt the main competencies to conduct the educational activities, they were satisfied for the training course received, and they felt high levels of self-efficacy. The intervention was implemented with 1894 high school students (61% males; Mage = 15.68 years). In the short term, we found a significant increase of adolescents’ correct gambling knowledge, random events knowledge, and probabilistic reasoning ability, and a significant decrease of superstitious thinking, monetary positive outcome expectation, and gambling-related erroneous thoughts and fallacious behavioral choices. In the long-term, a significant decrease of gambling frequency, gambling versatility, and gambling problem severity was obtained. Overall, this work highlights the importance to train prevention program providers in order to optimize the effectiveness of large-scale gambling intervention programs towards adolescents.

Published: May 2022

Leadership plays a significant role in the performance of individuals and organizations. This paper investigates the impact of leadership styles on the innovative performance of female leaders in Pakistani Universities using a survey approach. This paper aimed to (a) discover a leadership style practiced by females and (b) discover the relationship between leadership style and the innovative performance of female leaders. Several female leaders, including faculty members, heads of departments, deans, coordinators, and directors, from public and private universities of Punjab (a province of Pakistan), were involved in this study. A sample of one hundred female leaders was selected using a multistage sampling method. In the first stage, five public and five private sector universities were selected through a simple random method. In the second stage, ten female leaders (five from each of the social science and basic science departments) were selected from each university through a purposive sampling method. The researchers adopted a reliable instrument to collect the survey data. The collected data were analyzed using SPSS (Version 26). Mean scores and Pearson correlation coefficients were used to discover the relationship between various variables. The investigation revealed that most female leaders practice the transactional leadership style in their universities. This study also discovered a moderate positive relationship between both leadership styles, namely transactional and transformational, and innovative performance. The study recommends that various workshops and seminars may be conducted to increase the practices of both leadership styles to enhance innovation in Pakistani Universities.
Analyzing a sport for development program’s logic model by using key actors’ perceptions: The case of Pour 3 Points organization in Montreal
Authors: Gadais Tegwen , Bardocz-Bencsik Mariann
Published: May 2022

Introduction

More work is needed on measuring the impact of Sport for Development (SFD) organization and on the managerial structures and processes for change. The purpose of the current study was to analyze the logic model (LM) of a SFD program in Canada that provides training for high school coaches in low socioeconomic communities in Montreal.

Methods

Key actors (i.e., coaches, program administrators, school directors, and sport coordinators; N = 22) were interviewed about their perceptions of the different components of the organization’s LM, namely the program’s context, the initial problem it addressed, its needs, objectives, input, output, and impacts.

Findings

Findings reveal the participants perceived the program as being successful by all key actors. Participants had similar understandings regarding the targeted problem and context, but their views differed regarding their understanding of the program’s activities. In addition, the key actors addressed issues of the structure and impacts of the SFD program and made suggestions to improve the program, including clarifying its objectives, reinforcing internal communication, and building stronger partnerships with the partner schools.

Conclusions

Findings from the present study provide recommendations to help improve the organization’s LM. In addition, these findings can help researchers and SFD administrators reinforce essential organizational program structures and activities for better management, evaluation, and improved impact on communities.
Dietary intake and its associated factors among in-school adolescents in Ghana
Authors: Hormenu Thomas
Published: May 2022

Introduction

Early-life nutrition related experiences may fuel the emergence of obesity and type 2 diabetes in adolescence. The adoption of unhealthy dietary practices early in life is an indicator of adverse cardiometabolic health in adulthood. In-school adolescents’ dietary practices in Ghana have not been explored extensively despite increasing levels of obesity in adolescents. This study sought to examine dietary practices, socio-demographic disparities and the factors influencing dietary choices among in-school adolescents in Ghana.

Methods

A school-based, cross-sectional study was conducted in the Central region of Ghana in 2017. Using multistage sampling procedures, a total of 1,311 in-school adolescents were selected for the study. A modified version of the generic Global School Health Survey questionnaire on dietary practices was adapted and used for data collection. Percentage and frequency counts were used to report on the dietary practices, while Chi-square was used to determine socio-demographic variations in the dietary practices. Binary logistic regression was used to compute the influence of socio-demographic characteristics of respondents on the prevalence of healthy dietary behavior among in-school adolescents.

Results

The study revealed the prevalence of healthy dietary practices (49.9%, n = 654) among in-school adolescents in the region. The study also found increased frequency in consumption of soft drinks (93%, n = 1220) and toffees/sweets (90%, n = 1183) among in-school adolescents. However, low intake of breakfast (57%, n = 749) was observed among the adolescents. Significant disparities were observed in relation to gender, age, parental communication, academic performance and geographical location in the dietary practices of in-school adolescents. Furthermore, gender (OR = 1.36, P = 0.007), academic performance (OR = 2.19, P = 0.001) and geographical location (OR = 1.79, P = 0.001) were found to be significantly associated with dietary practices among in-school adolescents in the region.

Conclusions

There was low consumption of fruits and vegetables among adolescents. Fruits and vegetables consumption was associated with gender, academic performance and geographical location, and these may be a reflection that knowledge on healthy food choices and availability are important factors influencing dietary choices among in-school adolescents. School health policy interventions aimed at improving nutritional status among adolescents and enhanced fruit and vegetable consumption in the country should take into account the potential benefit of increasing availability of fruits and vegetables in schools, while reducing access to sweets and soft drinks in the schools and communities.

Published: May 2022

Objective

To assess whether there is an association between veterinary specialty and the quality of life of residents in AVMA-Recognized Veterinary Specialty Organizations™using the WHOQOL-BREF instrument.

Methods

This cross-sectional study used an online survey and data collection service for administration of the survey to veterinary residents during April 2021 to June 2021. Veterinary residents were contacted through their respective AVMA-Recognized Veterinary Specialty Organization™and through social media. Overall quality of life along with the domains of Physical Health, Psychological Health, Social Relationships, and Environment were measured using the WHOQOL-BREF instrument. Additionally, data on the demographics of participants were collected and investigated as potential confounders. Mean standardized scores (0 to 100) were compared among the specialties using the general linear model.

Results

792 residents from 21 veterinary specialties were included in the analysis. The results showed that overall quality of life and all four domains varied significantly among specialties after adjusting for significant demographic variables (allPs < 0.001). The mean standardized overall quality of life score was 54.3, ranging from 31.8 in Emergency and Critical Care to 56.3 in Laboratory Animal. The mean standardized quality of life scores were lowest for Psychological Health (50.3), followed by Social Relationships (55.0), Environment (61.4), and Physical Health (62.6). Residents in Emergency and Critical Care had the lowest adjusted average scores in all quality of life domains. Residents in Internal Medicine, Anesthesia and Analgesia, and Surgeons had lower quality of life scores across several domains when compared to other specialties.

Clinical relevance

This study provides insight into the mental health and general well-being of veterinary residents. The results can assist veterinary specialty organizations, universities, and mentors in developing appropriate supporting programs for residents. The results can also assist residents in recognizing and more efficiently caring for their individual mental health and well-being.
Sensitivity to gait improvement after levodopa intake in Parkinson’s disease: A comparison study among synthetic kinematic indices

Published: May 2022

The synthetic indices are widely used to describe balance and stability during gait. Some of these are employed to describe the gait features in Parkinson’s disease (PD). However, the results are sometimes inconsistent, and the same indices are rarely used to compare the individuals affected by PD before and after levodopa intake (OFF and ON condition, respectively). Our aim was to investigate which synthetic measure among Harmonic Ratio, Jerk Ratio, Golden Ratio and Trunk Displacement Index is representative of gait stability and harmony, and which of these are more sensitive to the variations between OFF and ON condition. We found that all indices, except the Jerk Ratio, significantly improve after levodopa. Only the improvement of the Trunk Displacement Index showed a direct correlation with the motor improvement measured through the clinical scale UPDRS-III (Unified Parkinson’s Disease Rating Scale–part III). In conclusion, we suggest that the synthetic indices can be useful to detect motor changes induced by, but not all of them clearly correlate with the clinical changes achieved with the levodopa administration. In our analysis, only the Trunk Displacement Index was able to show a clear relationship with the PD clinical motor improvement.
Runkolukusarjamallit ovat aikansa lapsia – onko eri-ikäisrakenteisiin metsiin soveltuvia parametrisia malleja tai menetelmiä?
Authors: Siipilehto Jouni
Published: May 2022

Metsätaloudessa on viime aikoina esiintynyt kasvavaa painetta metsien jatkuvan kasvatuksen vaihtoehtoon niin luonnon monimuotoisuuden, maiseman kuin hiilensidonnankin kannalta. Poiminta­hakkuisiin perustuvassa eri-ikäismetsätaloudessa optimaalinen runkolukusarja on laskeva. Tällaiset puuston rakenteet ovat käytännössä harvinaisia, koska metsätalous on viimeisten vuosikymmenien aikana suurelta osin perustunut alaharvennettujen tasaikäisrakenteisten metsien kasvatukseen. Tässä työssä tarkasteltiin Suomessa laadittuja läpimittajakaumamalleja alkaen ensimmäisestä, vuonna 1980 laaditusta Beta-jakaumamallista vuonna 2013 esiteltyyn Weibull-jakauman parametrien palautusmenetelmään. Tarkastelluista SB-jakaumamalleista yksi vaihtoehto oli laadittu Virossa. Kiinnostuksen kohteena oli, löytyykö kyseisistä parametrisistä jakaumamalleista tai menetelmistä eri-ikäisrakenteisten metsien runkolukusarjaan sopivia vaihtoehtoja. Vanhimpien jakaumamallien tuottamat runkolukusarjat eivät juuri muuttuneet ennustettavan metsikön rakenteen muuttuessa eri-ikäisrakenteisesta metsästä tasaikäisrakanteiseen viljelymetsään. SB-jakauman ennustemallit olivat kaikkein herkimpiä lähtöpuuston rakenteen muutoksille. Kuitenkin parametrien palautusmenetelmät olivat ennustemalleja luotettavampia, ja palautettu Weibull-jakauma oli yhteensopivin niin eri-ikäisrakenteisen kuin viljelykuusikonkin runkolukusarjojen kanssa.

Published: May 2022

Currently, tools to predict the aboveground and belowground biomass (AGB and BGB) of woody species in Guinean savannas (and the data to calibrate them) are still lacking. Multispecies allometric equations calibrated from direct measurements can provide accurate estimates of plant biomass in local ecosystems and can be used to extrapolate local estimates of carbon stocks to the biome scale. We developed multispecies models to estimate AGB and BGB of trees and multi-stemmed shrubs in a Guinean savanna of CÃ´te dâIvoire. The five dominant species of the area were included in the study. We sampled a total of 100 trees and 90 shrubs destructively by harvesting their biometric data (basal stem diameter , total stem height , stump area , as well as total number of stems for shrubs), and then measured their dry AGB and BGB. We fitted log-log linear models to predict AGB and BGB from the biometric measurements. The most relevant model for predicting AGB in trees was fitted as follows: AGB = 0.0471 () (with AGB in kg and in g cm m). This model had a bias of 19%, while a reference model for comparison (fitted from tree measurements in a similar savanna ecosystem, Ifo et al. 2018) overestimated the AGB of trees of our test savannas by 132%. The BGB of trees was also better predicted from ÏDb2H as follows: BGB = 0.0125 () (BGB in kg and in g cm m), with 6% bias, while the reference model had about 3% bias. In shrubs, AGB and BGB were better predicted from together with the total number of stems (). The best fitted allometric equation for predicting AGB in shrubs was as follows: AGB = 0.0191 () . This model had about 1.5% bias, while the reference model overestimated the AGB of shrubs of Lamto savannas by about 79%. The equation for predicting BGB of shrubs is: BGB = 0.0228 () that overestimated the BGB of the shrubs of Lamto savannas with about 3% bias, while the reference model underestimated the BGB by about 14%. The reference model misses an important feature of fire-prone savannas, namely the strong imbalance of the BGB/AGB ratio between trees and multi-stemmed shrubs, which our models predict. The allometric equations we developed here are therefore relevant for C stocks inventories in trees and shrubs communities of Guinean savannas.DbHSSnÏDb2H0.915ÏDb2Hâ1ÏDb2H0.6899ÏDb2Hâ1ÏDb2HnÏDb2H0.6227n0.9271ÏDb2H0.7205n0.992

Published: May 2022

Objective: The study investigated our institutional learning curve for the ROSA ONE spine system (ROSA) based on ROSA usage time.Methods: ROSA was designed to provide high accuracy for spinal pedicle screw placement through a built-in tracking technique. This study was conducted from November 2018 to January 2021. The time taken to complete each step of the robotic workflow was recorded. Patient demographics, comorbidities, surgical indications, and number of screw placements were examined in subgroup analysis. The Curve Fitting-General package (a part of NCSS 2021 software) was used to fit a mathematical model to the learning curve. Patient demographics, imaging data, and surgical time were reviewed retrospectively.Results: A total of 167 patients who had undergone surgery were included. The mean total ROSA usage time was 107.1 ± 27.3 minutes. The estimated learning rate was 90.4%, and the largest slope change occurred close to the time of the 20th surgery. The observed overall learning trend in the 4-screw group could be attributed to screw planning. The presence of scoliosis (p = 0.73) or spondylolisthesis (p = 0.70) did not significantly influence the mean total time (TT) for all patients; however, the mean TT differed significantly (p < 0.01) among subgroups stratified by body mass index, screw number placement, and thoracic spine involvement.Conclusion: To the best of our knowledge, this is the first study to examine the learning curve for the various crucial steps of ROSA-guided pedicle screw placement. The indicative learning curve involved 20 patients who had undergone surgery.

Published: May 2022

Objective: To evaluate cervical facet joint degeneration using a newly developed classification, investigate its prevalence and relationship with cervical degenerative spondylolisthesis, and clarify its clinical significance in patients with degenerative cervical myelopathy (DCM).Methods: This study included 145 consecutive patients with DCM who underwent surgical treatment. Clinical variables and radiological findings were analyzed. A new 6-grade computed tomography (CT) classification for cervical facet joint degeneration was adapted, and its prevalence was evaluated by categorizing the joints into those at responsible and those at nonresponsible spinal segmental levels. We evaluated the association between rapidly progressive myelopathy and the presence of significant facet joint degeneration or spondylolisthesis at the responsible segmental level.Results: Finally, 140 patients with a mean age of 64.1 ± 12.8 years were analyzed. The prevalence of grade 1, 2, 3, 4, 5A, and 5B classification in all facet joints was 72.0%, 9.5%, 10.9%, 4.3%, 2.9%, and 0.4%, respectively. There was a statistically significant difference in the distribution of CT grades between the joints at the responsible and nonresponsible segmental levels (p < 0.001), with a high prevalence of grade 4 or 5B degeneration at the responsible segmental level, reflecting articular irregularity. There was also a statistically significant relationship between rapidly progressive myelopathy and grade 4 or 5B degeneration at the responsible segmental level (p < 0.001), but not between rapidly progressive myelopathy and spondylolisthesis (p = 0.255).Conclusion: This novel CT classification for facet joints deserves additional evaluation in patients with DCM. Abnormal findings on the articular surfaces might be related to the progression of myelopathy.
Digital Track Map for the VEXA expert system
Authors: Hlubuček Adam
Published: May 2022

This paper aims to summarize possible solutions of a Digital Track Map proposal, designed to become a data source for the VEXA decision-making system. The VEXA project is carried out in cooperation of the Department of Applied Mathematics at the Czech Technical University in Prague – Faculty of Transportation Sciences and the AŽD Praha s. r. o. company.The Digital Track Map is an indispensable data source describing the railway line intended for the VEXA supervised trains operation and its surroundings. Being created in the ArcGIS Pro software environment, the digital map allows individual objects to be visualized and handled as standard GIS features and described by related data stored in a geodatabase.Depending on the object class, the object location can be expressed in different ways. Not only physical location (directly expressible using GIS features) but also functional location (as the objects relate to a particular track) must be considered.
Construction 4.0 in the concept of the railway
Authors: Krupík Pavel
Published: May 2022

The digital and technological innovations that have been developing massively in recent years are often referred to as the 4th Industrial Revolution or Industry 4.0. The construction industry seems to be somewhat on the sidelines. The big topic is BIM (Building Information Modelling), but this is only one component of the contemplated Construction 4.0. Other topics, if not completely neglected, are minimally neglected in the Czech Republic. Yet, and perhaps for this very reason, it is very important to address them.This article looks at the description of the different elements of the Construction 4.0 concept and their possible application in transport, through the overall digitisation of the railways.

Authors: Dhar Prasenjit , Gayan Mithu Anjali
Published: May 2022

The official website of any organisation provides authentic information about it. The current study is a novel attempt to explore international library association websites and assess those websites based on web content evaluation and webometric parameters. Several library websites have been analysed by researchers. However, the same has not been attempted regarding the library association website at the international level. International library associations indexed by American Library association’s website were taken as the sample. Data were collected using a link analysis tool from https://moz.com/ which helps in determining Domain Authority, Page Authority, in-links, and out-links; Google was used for the links. Official websites of the library associations were visited for the website evaluation with a well-structured checklist having 19 criteria. International Association of Law Libraries is found to have the highest simple web impact factor and external web impact factor. In contrast, the Association of Jewish Libraries has the highest internal web impact factor. All the websites examined in this study are hosted under the .org domain. The study revealed that 7 out of 8 (87.5 %) international library association websites’ Domain Authority and Page Authority is below 50. Essential information like customer service, currency, and FAQ are not available on the websites. The results of this study will help the library associations in re-structuring and better maintenance of their website.
Jaime Álvarez Llanos: Política en el Atlántico a principios de siglo XX. Barranquilla: Ediciones Uninorte, 2003, 139 páginas.
Authors: González Arana Roberto
Published: May 2022

El investigador costeño y docente de la Universidad del Norte, Jaime Álvarez Llanos, magíster en Historia de la Universidad Nacional de Colombia y licenciado en Ciencias Sociales de la Universidad del Atlántico, nos presenta una obra sobre una temática muy poco explorada en la historiografía nacional. Los balances más conocidos sobre partidos e historia de movimientos políticos poco han hecho alusión a la historia del departamento del Atlántico, constituyéndose, por tanto, este trabajo, en una obra de especial interés.
Memorias enfrentadas: Centenario Nación y Estado 1910-1921
Authors: Román Romero Raúl
Published: May 2022

Se presenta el conflicto entre las ciudades del interior del país y las de la costa Caribe colombiana en el marco de las celebraciones centenarias de la independencia de Colombia, señalando como la conmemoración del 20 Julio de 1910 y 7 de Agosto de 1919 se presentaron como eje fundamental para la construcción de una memoria nacional. De esta manera se demuestra que el intento de implantar una memoria compartida a partir de los procesos históricos y las acciones realizadas desde el centro del país, para que se identificara todo el territorio colombiano, escenificó conflictos con las regiones y las localidades que tenían sus propias memorias. En este sentido presentaré la puesta en escena de unas contramemorias locales que hacen evidente las dificultades para construir una memoria nacional.

AUTONOMIA Y REBELIONES WAYUU EN EL PERIODO REPUBLICANO.
Authors: Paz Reverol Carmen Laura
Published: May 2022

La actitud beligerante de los Wayuu en el siglo XIX es explicado a partir de su organización social y principios consuetudinarios. En este periodo se redefine la respuesta Wayuu. Las rebeliones tienen su particularidad, no son de gran magnitud y circulan los rumores de invasión a la fortaleza de las Guardias de Afuera que no llegaron a concretarse. Hay un mayor reconocimiento de la especificidad social Wayuu por parte de las autoridades, se establecieron alianzas estratégicas con algunos jefes de parcialidad y se reconocieron las leyes consuetudinarias, las recompensas y el regalo ampliaron su función. El carácter autónomo ha dado permanencia en el tiempo a un modo de vida sustentado en una particular cosmovisión.
MARACAIBO Y SU CIRCUITO AGROEXPORTADOR EN EL SIGLO XIX.
Authors: Cardozo Galué Germán
Published: May 2022

La producción y comercialización del café andino venezolano y del norte de Santander, entre otros frutos, hacia el Caribe y el Atlántico hizo del puerto de Maracaibo, a finales del siglo XIX, la primera aduana de Venezuela en cuanto a la importación y exportación de capitales. Esta consolidación del circuito agroexportador marabino fue impulsada y concretada, fundamentalmente, por el establecimiento de varias firmas alemanas desde mediados de siglo. Dada la trascendencia que tuvo este proceso para la vida económica y relaciones socioculturales de la región histórica de la extensa cuenca del Lago de Maracaibo con el nororiente colombiano y el Caribe, en este artículo se reconstruyen las características de la actividad productiva, redes comerciales, desarrollo de la vialidad, medios de transporte y establecimiento de capitales y firmas comerciales regionales, nacionales, caribeñas y europeas en el circuito agroexportador marabino.

Andares sinuanos y habituación etnográfica
Authors: Arocha Jaime
Published: May 2022

En este artículo me refiero a la influencia de los afrosinuanos en mi adiestramiento etnográfico. Me aproximé a ellos cuando aún era estudiante de ingeniería mecánica y formaba parte del Grupo de Acción Comunal de la Universidad de los Andes. Las diversidades que fui descubriendo nutrieron las conversaciones que sostuve con Alicia y Gerardo Reichel-Dolmatoff cuando inauguraban el Departamento de Antropología de esa universidad. La intensidad de esos diálogos no sólo me llevó a cambiar de carrera, sino a optar por el estudio de las causas de la violencia en Colombia como futura tesis doctoral.
TRAS LAS HUELLAS DE LA CANDELARIA EN LOS LITORALES COLOMBIANOS.
Authors: De la Rosa Solano Laura
Published: May 2022

En Colombia la fiesta de la Virgen de la Candelaria es una celebración de gran trascendencia en numerosos pueblos y ciudades, entre los que se encuentran Cartagena y Magangué (Bolívar) y Paimadó (Chocó). Allí, y en otros lugares de los litorales colombianos, la devoción religiosa tiene una característica muy particular: una relación de cercana familiaridad que se establece entre santos y creyentes, la cual se manifiesta en las singulares formas de celebrar las fiestas patronales; poner a bailar a los santos, atribuirles relaciones sentimentales, emborracharlos, celebrar sus días tomando y bailando son expresiones comunes del fervor de los habitantes de ambos litorales. Este artículo presenta un breve recorrido por el origen de la Candelaria en esas tres localidades y algunas descripciones de las celebraciones que allí han tenido lugar en diferentes momentos históricos, lo cual nos permite plantear posibles relaciones culturales entre ambos litorales presentes desde la época colonial y vigente todavía en la actualidad.
“Self-determination is not a sin; it is a human right, a God given right”: Autonomismo y religion bautista en San Andrés Isla.
Authors: Guevara Natalia
Published: May 2022

El presente artículo aborda de manera general los nexos de los pastores y la religión bautista con el movimiento autonomista raizal de la isla de San Andrés. El documento brinda un panorama breve sobre la relación del Estado colombiano con el Archipiélago, la cual incluyó la censura a la lengua inglesa y criolla y a la religión protestante. Así, el artículo establece los orígenes de la participación de las iglesias bautistas en las reivindicaciones a favor de la identidad isleña en la resistencia de los pastores y los fieles protestantes ante las políticas integracionistas nacionales que surgían en el marco de la nación monocultural proclamada en la constitución de 1886. Si bien, a partir de la década de 1960 la resistencia raizal se manifestó en diversos movimientos de carácter secular, a finales de la década de 1990 los pastores retomaron el liderazgo en las demandas por la defensa de la identidad isleña mediante un discurso religioso que se entremezcla con lo político tanto en el espacio de la iglesia como en manifestaciones públicas realizadas en la isla. El artículo propone que el papel de los pastores en el movimiento raizal puede ser comprendido, por una parte, mediante la tradición antiesclavista de la religión bautista a lo largo del Caribe anglófono y, por otra, por la influencia de la iglesia en la vida social isleña como un indicador de respetabilidad, lo cual le permite convocar a la comunidad y ampliar el alcance de las demandas autonomistas del movimiento raizal. Finalmente, el documento plantea que el papel de los pastores como mediadores se enmarca dentro de una tradición más amplia de resolución pacífica del conflicto, expresada en el Caribe mediante la polirritmia, la cual permite la coexistencia de diversas tendencias que no se excluyen mutuamente.
Tardes de rancheria: ¿una cultura imaginada?
Authors: Urrego R Manuela
Published: May 2022

Hoy en día la industria del turismo es una de las mayores generadoras de riquezas a nivel mundial. No es una novedad saber que ha llegado a casi todos los rincones del planeta, satisfaciendo hasta los más extravagantes gustos. Dentro de ese espectro, existe una modalidad llamada Etnoturismo, en la cual los elementos simbólicos de una cultura determinada se transforman en un producto comercial que se ofrece como atracción turística. El siguiente artículo trata de ilustrar por medio de un plan etnoturístico que se realiza en la Guajira Colombiana, las relaciones y los tipos de intercambio que se dan en dicho escenario entre sus participantes, a decir los espectadores o turistas y el espectáculo, en este caso, indígenas Wayúu.

Siguiendo sus pasos: Explorando el activismo sociopolítico de los puertorriqueños en Nueva York desde una perspectiva Afrocéntrica
Authors: Denis-Rosario Milagros
Published: May 2022

Muchos estudios destacan que los puertorriqueños no encajan en la definición racial americana de "negro o blanco", y que debido a esta "singularidad" la experiencia racial puertorriqueña se debe medir de manera diferente. Este trabajo evalúa las actividades de puertorriqueños negros que llegaron y establecieron en Nueva York y quienes a pesar de enfrentar problemas de adaptación, racismo y pobreza persistente, forjaron una identidad la cual resuena con la experiencia y perspectiva de Arturo Schomburg, quien como puertorriqueño negro fue uno de los pioneros de la tradición afrocéntrica. Como historiadora en este artículo reviso la vida y obra de Schomburg y examino su gesta sobre el papel central de África y sus descendientes en la historia del mundo. También reviso la filosofía del historiador surafricano C. Tsehloane Keto, quien postula la centralidad de la historia de África en la interpretación de la experiencia de las personas de ascendencia africana en los Estados Unidos y en todo el mundo. Enmarcado en el contexto del trabajo de Keto y de Schomburg recalco que el proceso de la construcción de la identidad nacionalista cultural puertorriqueña en la ciudad de Nueva York demuestra un aspecto de la identidad "Nuyorican" la cual se caracteriza por una corriente afro-céntrica que va a la par con el movimiento negro afroamericano.
