Physical activity intention and attendance behaviour in Finnish youth with cerebral palsy – results from a physical activity intervention: an application of the theory of planned behaviour
Authors: Ruiz Alfredo , Ng Kwok , Rintala Pauli , Kaseva Kaisa , Finni Taija
Published: December 2021

Physical activity is associated with better health in individuals with cerebral palsy (CP). Numerous physical activity interventions have been designed to promote physical activity among youth with CP. No previous studies have explored the factors contributing to the intention to participate and predicting attendance behaviour for these interventions. Using theory of planned behaviour (TPB), this study explored the prediction of physical activity intention and attendance behaviour in a physical activity intervention aiming to promote physical activity in a sample of young individuals with CP. Males with CP aged 9–21 years were asked to complete measures of attitude, subjective norms, perceived behavioural control and, intentions towards a physical activity intervention. Participants had no cognitive impairments to understand and follow instructions, were categorised into Gross Motor Function Classification System I–III, did not receive any specific lower limbs’ medical treatment, or did not participate in a strength training program for lower limbs within 6 months before the study. Subjective norms were found to be the only significant predictor of intention, accounting for 83% of variance in intention. Intention and perceived behaviour control were found to be a nonsignificant predictor of attendance behaviour in youth with CP. The results show that TPB is a relevant tool in the prediction of intention towards a physical activity intervention in Finnish youth with CP.

Authors: Song Eun-Ju , Lee Eun-Jung , Kwon Hae-Yeon
Published: December 2021

The purpose of this study was to investigate the static and dynamic balance and body activities after administering a trunk stability exercise program using a sling for children with spastic cerebral palsy of Gross Motor Function Classification System (GMFCS) levels III–IV. This study was conducted based on a quasi-experimental study design. Six of the study participants were assigned to the control group and six were assigned to the experimental group using simple random sampling. Both groups underwent a double-blind clinical trial study in which exercise therapy was performed for 40 min twice a week for 8 weeks. The experimental group underwent the sling exercise program and the control group underwent neuro-developmental treatment. The results showed that static and dynamic balance were significantly different before and after intervention in both the experimental and control groups (P<0.05), and there was also a statistically significant difference between the two groups (P<0.05). Gross motor function and activities of daily life showed significant improvement before and after intervention in the experimental group (P<0.05), but there was no statistically significant difference in the control group (P<0.05). There was a statistically significant difference between the two groups (P<0.05). Therefore, the sling exercise program can be used as an effective treatment for improving balance and physical activity in children with cerebral palsy of GMFCS levels III–IV who have difficulty walking. In addition, such exercise will have a positive impact on the independence of such children and help them to participate in social activities.
Effect of treadmill exercise combined with bone marrow stromal cell transplantation on atrophy-related signaling pathway in the denervated soleus muscle
Authors: Cho Yeong-Hyun , Seo Tae-Beom
Published: December 2021

The purpose of this study was to investigate whether combination of low-intensity exercise with bone marrow stromal cell (BMSC) transplantation could regulate protein kinas B (Akt)- mammalian target of rapamycin (mTOR) and Wnt3a-β-catenin signaling pathways for prevention of soleus muscle atrophy after sciatic nerve injury (SNI). The experimental rats divided into 5 groups (n= 10): normal control group, SNI+sedentary group (SED), SNI+low-intensity treadmill exercise group (TEX), SNI+BMSC transplantation group (BMSC), SNI+TEX+BMSC transplantation group (TEX+BMSC). Sciatic nerve crush injury was applied into the middle of thigh twice for 1 min and 30 sec at interval. Low-intensity treadmill exercise was comprised of walking at a speed of 4 to 8 m/min for 30 min once a day. cultured BMSC at a density of 5× 106 in 50-μL phosphate-buffered saline was injected into the distal portion of the injured sciatic nerves. TEX+BMSC group dramatically upregulated expression levels of growth-associated protein-43 in the injured sciatic nerve at 2 weeks postinjury. Also, although Akt and mTOR signaling pathway significantly increased in TEX and BMSC groups than SED group, TEX+BMSC group showed more potent increment on this signaling in soleus muscle after SNI. Lastly, Wnt3a and the nuclear translocation of β-catenin and nuclear factor-kappa B in soleus were increased by SNI, but TEX+BMSC group significantly downregulated activity of this signaling pathway in the nuclear cell lysate of soleus muscle. Present findings provide new information that combination of low-intensity treadmill exercise might be effective therapeutic approach on restriction of soleus muscle atrophy after peripheral nerve injury.

Emergency practitioners' motivations and acceptance of COVID-19 vaccination
Authors: Andrews Nate , Déziel Jackson D
Published: December 2021

Background:

Vaccination against the SARS-CoV-2 virus is an essential contributor to ending the pandemic. Acceptance of the vaccine among emergency medical service (EMS) professionals is largely unknown.

Methods:

A survey was distributed to EMS professionals. Participants responded to questions about their experiences of COVID-19, if they had received a COVID-19 vaccine, and personal reasons behind their decision for having it. Descriptive statistics were calculated, and multivariate logistic regression was used to produce adjusted odds ratios.

Findings:

A total of 1087 survey responses were collected. Among respondents, 65% had received a full COVID-19 vaccine dose and 33% had not. Of those who had not, 81% said they were unlikely or very unlikely to receive a vaccine. Certification level, age and education were statistically significant factors for vaccine acceptance.

Conclusion:

Age, education and certification level are statistically significant factors in COVID-19 vaccine acceptance among EMS professionals. Additional research is needed to identify best practices to combat vaccine hesitancy.
Considerations on out-of-hospital pain assessment of a diverse population
Authors: Alinier Guillaume , Dippenaar Enrico , Gangaram Padarath
Published: December 2021

Nearly all medical emergency calls are related to someone experiencing some form of discomfort—either due to trauma or pain. Initial pain assessment may be undertaken over the telephone by an emergency medical dispatcher, without seeing the patient; however, the next key moment in pain assessment is completed patient-side by the paramedic. This inquiry is detailed and guides the paramedic in the formation of a differential diagnosis and provision of appropriate pain management. The research team recently conducted and published a study on pain assessment which raised concerns on the subjectivity of pain scoring. The work presented was in the context of a very multicultural environment. The aim of this commentary article is to further explore this topic and encourage health professionals to reflect on this aspect of patient assessment.
Do trade certifications alleviate economic and social deprivations of plantation workers? A study of the tea plantation sector in India
Authors: Viswanathan P.K.
Published: December 2021

This paper explores the important question whether trade certifications alleviate the economic and social deprivations of workers in tea plantations in India. Following a critical assessment of the historic deprivations faced by tea plantation workers, the author reviews the potential implications of various certifications adopted by tea plantations in India, including, Fairtrade (FT), RFA, ETP and Trustea. As a case for empirical analysis, the paper specifically examines FT certification and its impacts on tea plantation workers with particular reference to three certified tea estates located in the Nilgiris region in Tamilnadu (South India) and Assam (North-East India). The analysis endorses many of the findings of earlier studies on Fairtrade certification. Yet, it also provides very useful additional insights in terms of explaining why the adoption of certifications, especially FT certification, by tea plantations does not yield the intended outcomes with respect to amelioration of the deprivations suffered by the plantation workers. It reveals that, despite more than two decades of engagement with FT certifications, tea plantations are unable to make significant improvements in the lot of the plantation workers due mainly to the fact that the FT premiums that the tea estates receive are nominal and quite variable across years. It concludes that, given that the domestic consumption demand for tea has been growing in India, it is also crucial to focus on the domestic market through the design and promotion of appropriate certification standards (integrating the finest elements of existing ones) that would contribute towards improving the status as well as working and living conditions of plantation workers. This would also help mitigate the huge disparity in wages and earnings of workers between the south and north Indian states that emerge from the study.
Binocular stereo-microscopy for deforming intact amoeba
Authors: Matsumoto Kenji , Nishigami Yukinori , Nakagaki Toshiyuki
Published: December 2021

A powerful and convenient method for measuring three-dimensional (3D) deformation of moving amoeboid cells will assist the progress of environmental and cytological studies as protists amoebae play a role in the fundamental environmental ecosystem. Here we develop an inexpensive and useful method for measuring 3D deformation of single protists amoeba through binocular microscopy and a newly proposed algorithm of stereo-scopy. From the movies taken from the left and right optical tubes of the binocular microscope, we detect the 3D positions of many intrinsic intracellular vesicles and reconstruct cellular surfaces of amoeboid cells in 3D space. Some observations of sampled behaviors are shown in a single-celled organism of Amoeba proteus. The resultant surface time series is then analyzed to obtain surface velocity, curvature and volume increasing rates of pseudo-pods for characterizing the movements of amoeboid cells. The limitations and errors of this method are also discussed.
Multi-angle excited MOI and image processing strategies specified for detection of orthogonal weld defects
Authors: Wang Congyi , Gao Xiangdong , Ma Nvjie , Liu Qianwen , Liu Guiqian , Zhang Yanxi
Published: December 2021

This paper develops an integrative scheme combining new image acquisition, filtering and enhancement methods specified for orthogonal weld defect detection based on magneto-optical imaging (MOI) technique. For image acquisition, a controllable magnetic system enabling rotation of magnetic angles is invented to accurately collect MO images. Multiple images are acquired, yet few are utilized for further processing in the conventional method based on human subjective preferences, bearing chances that images containing defects are discarded. Therefore, we turn to an automated-filtering system to scrutinize MO images and filter effective images through Bhattacharyya coefficient screening method. This not only elevates efficiency and objectivity but also eliminates missed inspection. For image enhancement, normalization method is used to balance the image intensity, followed by image fusion and edge extraction by a two-dimensional gradient method. Our pre- and post-processing approaches significantly improve accuracy in defect recognition and precision in MO images.

Published: December 2021

Pinpoint damage is the main type of bulk damage in potassium dihydrogen phosphate (KDP) crystals in high-power lasers. Using time-resolved microimaging, we observed the complete dynamic evolution of pinpoint damage in a KDP crystal. We analyzed changes in the patterns of dark zones formed by decreasing probe transmittance in transient images throughout the process. The mechanical properties of stress waves in KDP crystals were further studied by a depolarized shadowgraph experiment and theoretical simulation. The dynamic evolution of mechanical stress waves was observed, and the correlation between mechanical failure due to stress waves and the static characteristic damage morphology was established.
Multiplexed Mach-Zehnder interferometer assisted ring resonator sensor
Authors: Yadav Mukesh , Aksnes Astrid
Published: December 2021

A Mach-Zehnder interferometer assisted ring resonator configuration (MARC)-based multiplexed photonic sensor with a large measurement range is experimentally demonstrated. The presented MARC sensor consists of a balanced Mach-Zehnder interferometer and a ring resonator acting as a sensing component. It produces transmission responses with unique spectral signatures, which depend on the physical angular separation between the through port and the drop port waveguides. These unique spectral signatures enhance the effective free spectral range of ring resonators. Hence MARC sensors with a large measurement range are realized. We experimentally demonstrated that the measurement range from the MARC with 135° angular separation is 8x larger than a standard ring resonator. Moreover, by utilizing the MARC, we distinguished the responses from two and three ring resonators multiplexed together. These results verify proof-of-principle for the MARC-based sensors. This inexpensive compact multipurpose device holds promise for numerous applications.
Parity-time symmetry in monolithically integrated graphene-assisted microresonators
Authors: Wen Hao , Ren Linhao , Shi Lei , Zhang Xinliang
Published: December 2021

Recently, optical systems with parity-time (PT) symmetry have attracted considerable attention due to its remarkable properties and promising applications. However, these systems usually require separate photonic devices or active semiconductor materials. Here, we investigate PT symmetry and exceptional points (EPs) in monolithically integrated graphene-assisted coupled microresonators. Raman effect and graphene cladding are utilized to introduce the balanced gain and loss. We show that PT-symmetry breaking and EPs can be achieved by changing the pump power and the chemical potential. In addition, the intracavity field intensities experience suppression and revival as the graphene-induced loss increases. Due to the unique distribution of optical field, tunable nonreciprocal light transmission is theoretically demonstrated when introducing the gain saturation nonlinearity. The maximum isolation ratio can reach 26 dB through optimizing the relevant parameters. Our proposed scheme is monolithically integrated, CMOS compatible, and exhibits remarkable properties for microscale light field manipulation. These superior features make our scheme has promising applications in optical communication, computing and sensing.
Dank der Schreibschraube zu Einsichten über Schreiben, Coaching und den Deutschschweizer Schreibcoachingmarkt
Authors: Burkhalter Katrin
Published: December 2021

Die Schreibschraube ist eine Metapher. Sie veranschaulicht insbesondere die vorwärtsgerichtete Schlaufenförmigkeit des Schreibprozesses. Sie ist aber auch ein Werkzeug, und zwar in zweierlei Hinsicht: indem sie erstens in einem sich an Scaffolding ausrichtenden Lehr-Lern-Setting als Unterstützung dient, und indem sie zweitens ein epistemisches Werkzeug für mich darstellt, dank dessen Einsatz ich zu neuen Erkenntnissen über Schreiblehre, Schreibcoaching und Schreibberatung sowie deren jeweilige Kontextsensitivität gelange. Im vorliegenden Artikel diskutiere ich, zu welchen Einsichten über den Deutschschweizer Schreibcoachingmarkt ich dank der Schreibschraube gelangt bin.

Die Schreibschraube wurde im Deutsch-als-Erstsprache- sowie im Deutsch-als-Fremdsprache-Setting eingesetzt, und zwar in der Hochschullehre sowie im Coaching. Der Einsatz der Schreibschraube im Rahmen eines Schreibcoachings misslingt vorerst. Dieser Misserfolg führt mich zu Einsichten über Wesen und Grenzen des Schreibcoachings, aber auch darüber, wie sich Schreibcoaching von Schreiblehre und Schreibberatung abgrenzt. Weiter führt es mich zur Einsicht, dass eine sorgfältige Auseinandersetzung mit dem Zieltext von großer Wichtigkeit ist.
Transcending gender dichotomy through art teacher education in Zimbabwe
Authors: Dziwa Dairai Darlington , Postma Louise , Combrink Louisemarié
Published: December 2021

Zimbabwe is a patriarchal society characterized by gender dichotomy and male domination that permeates through social, educational and domestic spheres resulting in numerous challenges for art teacher education students. Expanding critical consciousness within art teacher education programmes is an imperative step towards developing art teachers who are self-aware and reflexive concerning the intersections of gender, art and education. This study investigated how engagement with visual art can provoke a heightened critical awareness about gender bias, stereotyping and equity among Zimbabwean art teacher education students. Sixteen selected art teacher education students (eight males and females) at the Great Zimbabwe University participated in the study. Participants were guided by researcher-constructed prompts for purposes of image making, interpretation and dialogue. Visual discourse analysis of the students’ visual narratives and discourse analysis of focus group transcriptions revealed several themes as well as evidence of critical reflection and expanded critical awareness related to gender issues. Visual and dialogic methods offer promise for critical engagement and reconciliation of tensions surrounding issues of gender amongst art teacher education candidates.
Towards a pedagogy of reconciliation and transformation: A peace education through art initiative in response to 26/11
Authors: De Mousumi
Published: December 2021

The 26/11 Mumbai attacks in India severely impacted the already strained Indo–Pak political relations and fuelled prejudice against the common people of Pakistan. Since the attacks, Indian people have found various expressions of collective memory and ways to commemorate the incident. While these serve as a remembrance of the attack, it also reinforces negative attitudes towards Pakistan and its people, hindering any prospects of peace and reconciliation. This article describes a peace education through art initiative implemented in a high school in Mumbai. It draws from a synergy of theoretical concepts in peace, reconciliation and conflict transformation for its curricular framework that has three inquiry processes: Examine–Envision–Envisage. This article describes the implementation and outcomes of the initiative that support the value of an integrated peace- and reconciliation-focused art education pedagogy aimed at promoting reconciliation in relation to ongoing/intractable conflicts. Furthermore, it highlights the importance of addressing negative emotions inherent in ongoing conflicts and how empathy might contribute towards reducing prejudice towards the ‘Other’.
Race-based mascots: Reflecting on university–community conversations
Authors: Bergmark Jennifer , Danker Stephanie H.
Published: December 2021

Two university art educators engaged in research to explore issues of race and representation through examining the histories of race-based mascots at their two Midwestern US universities. Collaborative inquiry allowed for reflective practice, dialogue and critical listening as part of extended conversations to examine the stereotyping of Indigenous culture and images with students and community members. Issues of race, representation, stereotyping and systemic racism were explored with university art education students, faculty and Myaamia citizens (Miami Tribe of Oklahoma) in a workshop setting. Conversations within the workshop aimed to extend understandings about the cultural and artistic traditions of the Miami Tribe and strengthen cross-institutional and community relationships. Post-workshop analysis of the collaborators’ correspondences was analysed to reveal three themes: relationships and voice, representation and acknowledgement. Reconciliation is discussed as ongoing and mutual effort involving a continuous process of critical reflection, listening and dialogue necessary for building relationships and to learn directly from Indigenous peoples.
El punto cubano como práctica cultural. Claves para su comprensión en la región occidental de Cuba
Authors: Carricaburu Collantes Amaya
Published: December 2021

El punto cubano es un género musical oriundo de Cuba, declarado por la UNESCO Patrimonio Inmaterial de la Humanidad en 2017. En el transcurso del pasado siglo, numerosas investigaciones han puesto el foco en sus características musicales propiamente, dejando a un lado su dimensión de práctica cultural, la cual ha propiciado diversos procesos de preservación y transmisión. Este artículo propone precisamente su valoración como práctica cultural, a partir de la importancia y el papel que diversas expresiones artísticas tienen dentro de este género musical y el carácter comunitario de sus fiestas. Toma como referencia el trabajo previo El punto cubano en Mayabeque. Tendencias de desarrollo (2013-2016) (Carricaburu, 2019). Partiendo de un análisis de los estudios sobre el género, aborda aspectos de su relación con la identidad cultural del cubano y centra su mirada en la propuesta de validación del concepto práctica cultural para este caso, mediante el análisis de las prácticas realizadas en la occidental provincia de Mayabeque. En definitiva, nos planteamos, a partir de un intenso trabajo de investigación de campo y el análisis comparativo de numerosas tonadas campesinas grabadas in situ, evidenciar la práctica estable y continuada del punto cubano en esta provincia.

Desde los años setenta en Venezuela se ha generado un movimiento de ensambles instrumentales de música venezolana, apegados a la tradición, pero que dan un paso más en composiciones, arreglos y técnicas, siendo difícil poder enmarcarlos en una forma de música específica. A partir de las ideas de música popular y música tradicional, nos acercamos a definir un concepto que nos ayude a entender la propuesta estética de dichas agrupaciones.
LOW RATES OF VITAMIN D SCREENING: CONCERN FOR AGING WITH POOR SKELETAL HEALTH IN THE OLDER MINORITIES
Authors: Rianon N.J. , Murphy K.P. , Dyer C.B. , Selwyn B.J.
Published: December 2021

Background: Regardless of discussion about vitamin D deficiency in minority population, there is a scarcity of information on vitamin D screening practice in older minority patients by their PCPs. Screening for risk factors does improve diagnosis and treatment of compromised skeletal health. Objective: To compare vitamin D screening rates between older patients from Caucasian and other non-Caucasian backgrounds including Blacks and Hispanics who were being treated by their PCPs for osteopenia, osteoporosis or related fractures. Design: Retrospective cross-sectional analysis. Setting: Electronic medical chart review from two urban primary care clinics (family medicine and geriatrics, Houston, TX) between January 2010 and December 2011. Participants: 133 patients 50 years or older who visited primary care clinics for osteopenia, osteoporosis or related fractures. Measurements: an order for 25-hydroxy vitamin D a year before or after an osteoporosis related visit. Results: Regardless of the clinic type, higher percentages of minority patients were not screened for vitamin D. While patients with older age from both groups were more likely to be screened, no single patient characteristic remained significant after adding clinic type to the logistic models. Conclusions: Lower rates of vitamin D screening put older minority patients at higher risk of aging with worsening skeletal health. Perspective and knowledge about vitamin D screening by PCP is recommended for future research to improve vitamin D screening and treatment in minority elderly.

Conclusion: Individuals living independently in their homes who use congregate feeding have reduced risk of malnutrition.
A DESCRIPTIVE STUDY OF THE NUTRITION-RELATED CONCERNS OF CAREGIVERS OF PERSONS WITH DEMENTIA
Authors: Anderson J.G. , Rose K.M. , Taylor A.G.
Published: December 2021

Objective: Family caregivers are the mainstay of caregiving support to persons with dementia, and often care for a family member with dementia for a decade or more prior to institutionalization or death. Malnutrition, including weight loss, is common among older adults with dementia, occurs throughout the disease process, and is associated with institutionalization and death. Nutrition education for caregivers is an important aspect of addressing the care needs of adults with dementia; however, nutrition education research in community-based persons and families experiencing dementia is minimal to non-existent. The need for tailored education resources ranks as highly important among caregivers; however, the nutrition concerns of caregivers in the home have not been identified. The purpose of the current study was to gather descriptive data about the nutrition-related concerns of family caregivers of persons with dementia. Design: A qualitative descriptive design using semi-structured interviews of caregivers of persons with dementia (n = 4) was used to collect the data. Thematic and content analysis was used. Results: Family caregivers experienced nutrition-related concerns and described a need for nutrition education to support the caregiving role. Four themes emerged: (1) meal preparation and food choices; (2) lack of appetite and eating behaviors; (3) making sense of existing nutrition information; (4) searching for reliable nutrition information. A discussion of each theme, including exemplars, is presented, along with suggestions provided by participants regarding how to address existing nutrition education resource needs.Conclusions: Issues surrounding care often are complex and require accurate and tailored information. Findings from the current study provide rich, valuable data regarding the needs of family caregivers with respect to nutrition concerns, allowing for the development, design, testing, and delivery of nutrition education resources and strategies.

Published: December 2021

Background: The ApoE genotype, atherosclerosis, status of inflammation, oxidative stress and co-morbidity may be detrimental to the elderly. Objectives: To identify biomarkers of aging. Setting: All subjects were Chinese elderly in Shanghai. Subjects: 549 outpatients (489 male, 60 female), divided into ≤74 year-old, 75-84 year-old and the oldest old (≥85 year-old ) groups. Methods: A univariate analysis was used to investigate 5 age-related categorical variables and 26 continuous variables. The related variables were used to find the independent biomarkers of aging by Multivariate logistic regression analyses. Results: The serum values of Glutathione peroxidase, HDL-C and C reactive protein, the number of co-morbidities and fundus atherosclerosis level were the main independent age-associated factors that influenced aging. Compared with ≥85 year-old individuals, ≤74 year-old individuals had fewer co-morbidities [OR, 0.757 (95% CI, 0.636, 0.902)], lower grades of fundus atherosclerosis [Grade 0: OR, 26.059 (95% CI, 4.705, 144.324)] and [Grade I: OR, 8.539 (95% CI, 3.555, 20.513)] and lower serum levels of HDL-C [OR, 0.127 (95% CI, 0.037, 0.433)]. However, 75-84 year-old patients had significantly lower plasma levels of GSH-px [OR, 0.986, (95% CI, 0.972, 1.00)], HDL-C [OR, 0.158 (95% CI, 0.054, 0.457)] and HsCRP [Grade I: OR, 8.516 (95% CI,1.630, 44.484)], [Grade II: OR,7.699 (95% CI,1.544, 38.388)] and [Grade III: OR,7.251 (95% CI,1.346, 39.070)]. Conclusion: The oldest old patients had significantly high anti-oxidant capability and serum HDL-C level. However, these patients also had a significantly high systemic inflammation, number of co-morbidities and grades of fundus atherosclerosis.

Dinâmica dos Territórios Camponeses em Alagoas: a articulação de famílias assentadas para ampliar a Agroecologia em áreas de reforma agrária
Authors: Santana José Ubiratan Rezende , Gervais Ana Maria Dubeux , Mattos Jorge Luiz Schirmer
Published: December 2021

Este artigo analisa o processo de ampliação da Agroecologia em territórios de reforma agrária e as nuances do acesso à terra por famílias camponesas nos assentamentos rurais. Os assentamentos de reforma agrária são constituídos a partir da organização de famílias camponesas, numa busca histórica pelo acesso à terra e pela regularização legal de seus territórios. Essa alteração no regime de uso e posse da terra tem significado o aumento na quantidade e na diversidade de alimentos produzidos nesses agroecossistemas, sobretudo quando há experiências consubstanciadas na Agroecologia, que é considerada uma ciência no campo da complexidade, utilizada como referência pelos movimentos camponeses para orientar a produção de alimentos saudáveis, locais, e com atenção às culturas camponesas e tradicionais. O estudo envolveu dois assentamentos do Estado de Alagoas, Flor do Bosque e Dom Helder Câmara, localizados nos municípios de Messias e de Murici, respectivamente. Os dados analisados foram obtidos do diagnóstico realizado pelo sistema Radis e de registros do diário de campo. Os resultados indicaram que as famílias inseridas na produção de base agroecológica e orgânica são responsáveis por um incremento na diversidade produtiva de 48% no Flor do Bosque e 39% no Dom Helder Câmara, com alimentos produzidos exclusivamente por elas. Identificou-se em ambos os assentamentos a presença de famílias que ainda não detêm a posse legal da terra, mas que produzem de forma agroecológica e orgânica. Tal fato adquire grande relevância, uma vez que isso implica diretamente os desdobramentos da territorialização do campesinato nesses assentamentos.
Drivers of vulnerability to climate change in the southernmost region of Bahia (Brazil)
Authors: Neves Frederico  Monteiro , Alvarez Guineverre , Corrêa Fábio Fernandes , Silva João Batista Lopes
Published: December 2021

The region that comprises the Atlantic Forest is one of the most degraded areas of the planet, being especially vulnerable in climate change scenarios, which project a mean temperature increase between 2ºC and 3ºC by 2070 for the Brazilian Northeast region. This article aims to analyze the main drivers of socio-environmental vulnerability in the Atlantic Forest region that comprises the southernmost identity territory of Bahia (Brazil) and their potential consequences for coping with climate change. To this end, historical data on land use and occupation was spatialized and evaluated, along with socioeconomic indicators and legal environmental adequacy in the municipalities that make up this territory. The results indicate four structural drivers that generate regional vulnerabilities: the persistence of deforestation; the continuous expansion of monoculture areas; the maintenance of low levels of well-being of the population; as well as a picture of legal environmental liabilities. Based on the analysis of these data, strategies are proposed to increase the adaptive capacity to climate change in this region, especially considering the role of municipalities as a central actor in the implementation of adaptation actions by incorporating into their existing planning instruments indicators and strategies that address the multiple current challenges, especially when the federal government seems to be neglecting climate change.
Ambiente, clases sociales y potencia emancipadora: contribuciones para una intervención social contrahegemónica desde los espacios académicos
Authors: Graziano Martín
Published: December 2021

Los espacios académicos poseen un amplio espectro de intervención en el tejido social en vinculación con colectivos socioambientales, escuelas y otras organizaciones sociales, en un tiempo actual atravesado por la urgencia de una crisis ecológica en ciernes. Argumentaré aquí que la constitución de alianzas contrahegemónicas entre la academia y diversos movimientos sociopolíticos de la clase trabajadora, en particular los movimientos sociales territoriales que agrupan a trabajadoras y trabajadores desocupados o marginados de la economía formal, permiten la intervención a través de la coproducción de conocimiento crítico al sistema y la implementación de prácticas ecosociales prefigurativas ligadas a la acción sociopolítica necesaria y conducente al cambio de sistema. Este tipo de alianzas abona a una práctica científica y académica que persiga el fortalecimiento de potencialidades emancipadoras en organizaciones sociopolíticas autónomas de la clase trabajadora, aspecto cada vez más necesario para revertir las crisis por venir.

Authors: Bravo Maria Laura , Álvarez Ana
Published: December 2021

El cinturón hortícola de La Plata, Buenos Aires, Argentina, constituye el polo de producción de hortalizas para consumo fresco más importante a nivel nacional en cuanto a cantidad producida y a productividad alcanzada. Esta producción abastece el Mercado Central de Buenos Aires, mercados mayoristas del conurbano bonaerense, de Rosario y de Mar del Plata. Las familias productoras que están en procesos de transición agroecológica, definida por técnicas y tecnologías sustentables con el ambiente y el sistema social, han desarrollado experiencias de circuitos cortos de comercialización que permiten acercar a productores y consumidores. El objetivo de este trabajo es compartir avances logrados de manera participativa en la definición de una herramienta que permita garantizar las verduras obtenidas en quintas familiares con manejo agroecológico a través del desarrollo de un Sistema Participativo de Garantía. Esta experiencia se enmarca en el Proyecto Institucional para el desarrollo tecnológico y social “Sistema Participativo de Garantía en la Horticultura Platense: construyendo soberanía alimentaria”, es bienal, acreditado y financiado por la Facultad de Ciencias Agrarias y Forestales de la Universidad Nacional de La Plata; y en el Proyecto de Extensión Universitaria “Sistemas Participativos de garantías. Herramientas construidas para procesos de transición agroecológica”, financiado por dicha universidad.
Acerca de la interpretación lógica/original del problema de marco y algunos subproblemas relacionados
Authors: Silenzi Maria Inés
Published: December 2021

Si bien existe cierto consenso en que el problema de marco es uno de los problemas más controversiales y difíciles de resolver dentro del campo de la filosofía de la mente, aún hoy no se ha logrado consensuar su definición ni solución. Es por esta razón, que nuestro principal objetivo es esclarecer la interpretación del problema de marco original, y algunos problemas que de ésta se derivan. Sostendremos que,  aún esta interpretación, de entre varias, posee varios aspectos y que no puede interpretarse como “un” sólo problema sino más bien como un conjunto de problemas estrechamente relacionados con la misma cuestión.
Perilaku Masyarakat dan Peran Pekerja Sosial dalam Membantu Korban Terdampak Pandemi Corona Virus Diseases (COVID-19)
Authors: Purdananto Fadlilah
Published: December 2021

Pandemi Corona Virus Disease (Covid-19) memiliki dampak yang signifikan ke perubahan perilaku masyarakat. Dampak tersebut memunculkan permasalahan berupa ketidakmampuan masyarakat dalam mengelola rasa curiga, takut, sikap over-protektif. Bila hal itu tidak diselesaikan dengan baik, maka dapat merusak hubungan sosial antar individu. Penelitian ini menggunakan metode deskriptif-analitis, dengan menggunakan teori psikodinamika. Hasil penelitian menunjukkan bahwa pekerja sosial berperan dalam mengubah perilaku masyarakat, sehingga mereka mampu menyelesaikan permasalahan sosial akibat dampak pandemi Covid-19. Peranan pekerja sosial, yakni: pertama, berperan dalam meningkatkan fungsi sosial individu-individu. Hal itu dilakukan pekerja sosial dengan memberikan pertolongan agar individu mampu memahami konflik (kepanikan/keresahan) pikiran-pikiran dan perasaannya. Kedua, pendampingan sosial kepada masyarakat. Hal itu dilakukan pekerja sosial dengan mengedukasi dan membantu mensosialisasikan kegiatan yang bertujuan untuk melakukan pencegahan atau penurunan penyebaran Covid-19.[The Corona Virus Disease (Covid-19) pandemic has a significant impact on changing people's behavior. This impact raises problems in the form of the community's inability to manage suspicion, fear, over-protection. If it is not resolved properly, it can damage social relations between individuals. This research uses descriptive-analytical method, using psychodynamic theory. The results of the study show that social workers play a role in changing people's behavior, so that they are able to solve social problems due to the impact of the Covid-19 pandemic. The role of social workers, namely: first, plays a role in improving the social function of individuals. This is done by social workers by providing assistance so that individuals are able to understand the conflict (panic/anxiety) of their thoughts and feelings. Second, social assistance to the community. This is done by social workers by educating and helping to disseminate activities aimed at preventing or reducing the spread of Covid-19.]
Play-Based Learning With Cantol Method for Developing Early Children's Linguistic Intelligence at Roudhoh Course Depok
Authors: Isnia Azmi Zulfa
Published: December 2021

This study describes the implementation of playing while learning children with the hook method and its implications for language development for early childhood at Roudhoh Depok tutoring. This research is descriptive research with a qualitative approach. The subjects of this study were PAUD students and educators at the Roudhoh Learning Guidance, Depok. Methods of data collection with interviews and documentation. Data analysis uses data analysis techniques from the Miles and Huberman model, consisting of data reduction, data presentation, and concluding. The results showed that the implementation of playing while learning with the hook method is a learning method that is given to introduce letters and how to read without coercion but with games that use visual aids and systems. Not spell, but hooks, which combine two letters (consonants and vowels) read together. The implication for the development of linguistic intelligence in early childhood is that it can produce students who can develop linguistic intelligence according to standards.
A Survey on the Use-Cases and Deployment Efforts Toward Converged Internet of Things (IoT) and Vehicle-to-Everything (V2X) Environments
Authors: Hejazi Hamdan , Bokor László
Published: December 2021

In the past few years, automotive Internet of Things (IoT) solutions have become one of the most significant IoT application areas in the shape of vehicular communication to connect vehicles and such the so-called Internet of Vehicles (IoV) to be used in Intelligent Transportation Systems (ITS) environments. With an increasing level of cooperation, ITS could facilitate smart city operations by providing cooperative intelligent traffic solutions. Modern Cooperative ITS (C-ITS) solutions have started to be implemented in the whole world with various deployment models and significant improvements in the integration of Vehicle-to-Everything (V2X) communication and IoT solutions. To highlight the current V2X technology evolution towards an IoT/IoV era, this paper presents a comprehensive survey about the convergence between IoT and V2X use-cases together with their supporting technologies in the cooperative ITS ecosystem worldwide. We show how IoT could enable advanced V2X applications to get widespread and increase ITS efficiency.

Sayung coast is a area with a growing residential, sea ranching, and industrial area. Those aspects produce create waste that could harm the environment, directly or indirectly. Plankton is a biologic component that is used to indicate the changes of water quality in waters that has been polluted. These goals of this research are to know the water quality in Sayung coast area from the abundance of the plankton,  physical-chemical parameter of the water, and also the status of water saprobity. The samples are taken in July 2017 and April 2018, in Sayung coast waters, Demak. Plankton sampling and water from 5 sampling stasions are considered to represent the diversity of the plankton and water stability. Plankton is sampled using plankton net No.25, then preserved using 70% alcohol + 4% formaldehyde. The abiotic data measureted is nitrate content, temperature, pH, salinity, DO, and turbidity. Data analysis are done using Shannon Weiner’s diversity index (H’), diversty index (e), domination index (C), saprobic index. The result shows that there are 49 species of planktons are found, which are 38 fitoplankton, and 11 zooplankton. The highest group is Bacillariophyta which is 14,24%. The diversty index value of H’ 1,58 – 2,45; therefore the Sayung coast waters is catagorized as stable. The index value of e ranges from 0,64 – 1; index C values ranges from 0,08 – 0,22; and the saprobirity index value is in β-Meso/Polisaprobik to α-Mesosaprobik phase with a very light to very high pollution levels. The physical-chemical parameter analysis of Sayung coast waters in overall is still suitable to support plankton’s life.
