The Status of Clinical Supervision in Therapeutic Recreation in 2020: A Follow-Up Study
Authors: Anderson Lynn , Page Jason , Zahl Melissa
Published: February 2022

Despite increasing attention among allied professions, clinical supervision within therapeutic recreation remains an under-researched topic. This has left the field with limited knowledge regarding the status of clinical supervision received by recreation therapists. Just one study has examined clinical supervision in RT (Jones & Anderson, 2004) and found that most recreation therapists were not receiving or giving clinical supervision. The purpose of this study was to gain a current understanding of the status of clinical supervision in TR/RT. An online survey yielded a response of 954 recreation therapists. Results indicated that most in TR/RT are not receiving or giving clinical supervision, which has worsened in the last 17 years. The majority of respondents indicated that they had not received training in clinical supervision, noted many barriers to supervision, and a need for training. Recommendations to increase access to clinical supervision as well as needs for future research are identified.

Assessing competence in teacher education: Development of university students’ problem-solving skills
Authors: Harangus Katalin
Published: February 2022

In our research, we examined the development of complex problem-solving skills among 1st-year teachers training undergraduate students in engineering at Sapientia Hungarian University of Transylvania (N = 73). The research aimed to determine whether knowledge transfer works among students in interpreting life-like, specific problems. A worksheet was used as a measuring tool. In compiling it, we applied the concept that tasks include computer-transferable algorithms (such as cryptography process, parallel computing, and constraints), and their solution does not require any special IT knowledge, only structured and logical thinking. The research reports on the extent to which teacher training students have acquired knowledge and problem-solving strategies related to certain disciplines. The obtained data shed light on the fact that the lack of an interdisciplinary approach hinders the recognition of the connections between the different fields of education.

Aching to be Understood: Vocational Rehabilitation Implications for Emerging Adults in Chronic Pain
Authors: Hunter Tameeka , Koch Lynn , Lusk Smith Stephanie , Hall Andrea Hampton
Published: February 2022

Background

Emerging adults, the developmental period ranging from the late teens through the 20s, experience chronic pain at an estimated rate of 7.6%–14.3% and report greater pain interference (i.e., pain that disrupts daily life activities) than middle-aged or older adults. Chronic pain can interfere with the completion of developmental tasks associated with biological, psychological, occupational, and social changes necessary to move from emerging adulthood into young adulthood. For these reasons, the impact of chronic pain may be more detrimental for emerging adults than for middle-aged and older adults.

Objective

To investigate the unique characteristics and vocational rehabilitation needs of emerging adults with chronic pain and to identify and implement policies, practices, and interventions that facilitate the achievement of vocational rehabilitation consumer’s self-determined goals.

Methods

The authors reviewed the literature on (a) common conditions that cause chronic pain in emerging adults, (b) the populations most at risk of experiencing chronic pain in emerging adulthood, (c) psychosocial aspects of chronic pain for this population, (d) vocational impact of chronic pain on emerging adults, and (e) the use of the disability centrality model to guide assessment and planning.

Conclusion

This literature review examines best practices related to vocational rehabilitation and emerging adults living with chronic pain. Comprehensive recommendations are provided that inform all phases of the vocational rehabilitation planning process, including services related to outreach and eligibility, counseling and guidance, physical and mental restoration, post-secondary education, job development and placement, and accommodation planning.

Published: February 2022

En la actualidad el turismo es considerado la mayor industria de servicios y uno de los principales ingresos económicos en muchos países. A lo largo de los años, han ido apareciendo nuevas tendencias turísticas que se diferencian por los distintos intereses de los viajeros. Una de estas tendencias es el enoturismo, el cual está enfocado en zonas de producción vitivinícola donde las bodegas dan a conocer sus productos. Una de las ciudades con más producción de vid en nuestro país es Lima y en ella podemos ubicar el distrito de Santa Cruz de Flores, que forma parte de la provincia de Cañete. Este distrito es conocido como la capital del vino por la gran producción que tiene de este producto, pero cuenta con una carente infraestructura para el enoturismo. Ante esta problemática se plantea hacer un Complejo Enoturístico en Santa Cruz de Flores el cual se enfoca en brindar un equipamiento turístico al distrito y de esta manera ayudar en la economía de los pobladores. El proyecto parte de una bodega vitivinícola y se complementa con un alojamiento y espacios públicos relacionados a la recreación, relajación y gastronomía. El proyecto se emplaza en un terreno natural que se encuentra rodeado de cerros y de campos agrícolas, lo que permite darle al usuario una experiencia más completa. Para el desarrollo del complejo se ha dado énfasis a cuatro criterios arquitectónicos que además fueron parte en la toma de partido: Adaptación al entorno, relación con la naturaleza, espacios intermedios y composición lineal.
El Protocolo Adicional al Acuerdo Marco y el ecosistema emprendedor como factores determinantes en las exportaciones de las startups Fintech peruanas en el marco de la Alianza del Pacífico durante el periodo de 2014- 2019
Authors:   , Abanto Delgado Maria Alessandra , Rojas Ponce Diana Milagros
Published: February 2022

A lo largo del tiempo, las finanzas siempre se han caracterizado por sostenerse en la tecnología. En los últimos años, luego de la crisis financiera del 2008, en 2014 se hizo visible la aparición de nuevas tecnologías en los mercados que han permitido el desarrollo de startups Fintech de manera acelerada, especialmente en países desarrollados de Europa, América del Norte y Asia. Las startups Fintech son emprendimientos disruptivos cuyos servicios están basados en herramientas tecnológicas que permiten transformar a las personas en usuarios netamente digitales. En el Perú, la aparición de startups Fintech tiene algunos años en el mercado, pero se ha visto una mayor fuerza en el crecimiento de esta industria debido a la participación de entidades del sector público y privado dentro del ecosistema emprendedor, y dentro de la región, el bloque regional que ha logrado fomentar avances en la regulación de esta industria es la Alianza del Pacífico. Dentro de este contexto, la presente investigación tiene como objetivo principal determinar si la firma del Protocolo Adicional al Acuerdo Marco de la Alianza del Pacífico y el ecosistema emprendedor peruano han sido factores que han influido en la exportación de startups Fintech peruanas durante el período 2014-2019. Para tal fin, en la investigación se aplicaron técnicas cualitativas basadas en entrevistas a emprendedores, expertos y funcionarios públicos relacionados a la industria Fintech. De esta manera, con el resultado del análisis se concluyó que los factores mencionados no fueron determinantes para la exportación de las startups Fintech peruanas. En contraste, se identificó que las capacidades del emprendedor peruano junto a una efectiva red de contactos y con un modelo de negocio innovador y disruptivo, permitieron que startups Fintech peruanas logren internacionalizarse rápidamente en países de la región durante el periodo de tiempo delimitado. Finalmente, cabe resaltar que, a la fecha, este tipo de emprendimientos enfocados en ofrecer servicios financieros disruptivos aún mantiene un bajo porcentaje de participación en la oferta exportadora de servicios.

Published: February 2022

Sarkasme adalah penggunaan kata-kata pedas untuk menyakiti hati orang lain, berupa cemoohan atau ejekan kasar. Kata sarkasme diturunkan dari kata Yunani sarkasmos yang berarti “merobek-robek daging seperti anjing”, “menggigit bibir karena marah”, atau ”berbicara dengan kepahitan”. Sarkasme dapat bersifat ironis, atau tidak, tetapi yang pasti adalah bahwa gaya bahasa ini selalu akan menyakiti hati dan kurang enak didengar. Pada penelitian ini akan dibuat model klasifikasi untuk memprediksi sarkasme pada judul berita berbahasa inggris dikarenakan judul berita menggunakan kata baku dan tidak ada salah pengejaan kata, menjadikan judul berita sebuah dataset yang tepat untuk dilakukan deteksi sarkasme. Algoritme Bidirectional Long Short-Term Memory (BiLSTM) yang merupakan salah satu algoritme deep learning digunakan pada penelitian untuk membuat model klasifikasi. Model ini lalu dibandingkan dengan model algoritme Long Short-Term Memory (LSTM) untuk memvalidasi keunggulan dari algoritme BiLSTM daripada algoritme LSTM dasar. Didapatkan akurasi validasi dari model sebesar 82,55%, precision validasi sebesar 82,36%, recall validasi sebesar 79,53%, dan f1 score validasi sebesar 80,92%.

Rice (Oryza sativa) is a grain that comes in third place among all grains after corn and wheat. 80 percent of Indonesians eat rice as a staple diet, especially in Southeast Asian countries, but the International Rice Research Institute (IRRI) reports that farmers lose 37 percent of their rice crops each year owing to pests and illnesses. Based on this study, it is critical to investigate the detection of rice pests and illnesses. Using the Convolution Neural Network (CNN) technique, an automatic classification system to identify and predict plant illnesses has been developed. A study titled Classification of Rice Leaf Diseases was undertaken by the author. The CNN Algorithm is being used to help farmers learn how to combat rice leaf diseases. Bacterial leaf blight, Rice blast, and Rice tungro virus were among the rice leaf types classified in this study. There are 6000 datasets in all, with 80% of them being training data, 10% being validation data, and 10% being testing data. The accuracy of the results obtained for epochs 25, 50, 75, and 100 varies. The best training accuracy results come from epoch 100, which has a 98% accuracy rate, and testing using a confusion matrix has a 98% accuracy rate. In diagnosing rice leaf diseases, the Convolutional Neural Network (CNN) algorithm delivers great accuracy.

Skin cancer is one of the most commonly diagnosed cancers worldwide, especially in the white population. One of the most dangerous skin diseases is melanoma cancer. Melanoma is a skin cancer that can develop in melanocytes, the skin pigment cells that produce melanin. Melanin is what absorbs ultraviolet rays and protects the skin from damage. Melanoma is a type of skin cancer that is rare and very dangerous, many laypeople have not been able to distinguish between ordinary moles and melanoma. Therefore, a study on the classification of melanoma skin cancer was carried out using the CNN method, where CNN was able to classify melanoma images. In CNN itself there is an architectural model, while the architecture used in this research is using conv2d layer, max pooling, flatten, dense, dropout, and using ReLu activation. The image size used in this architecture is 128x128, at the 50th epoch, an accuracy rate of 92.64% is obtained. It is hoped that this research can help the community in distinguishing normal moles and melanoma cancer.
Understanding Structural, Governance and Regulatory Incentives for Improved Utility Performance: The Case of Kenya and its Kenya Power
Authors: Twesigye Peter
Published: February 2022

The power sectors in most African countries face an enduring problem of utility performance – electricity utilities have failed to deliver adequate, reliable and competitively priced electricity to support economic growth and improve the welfare of their populations. Despite more than two decades of power sector re-forms, outcomes have been varied and often disappointing. Using a case study de-sign, we explore the five key enduring power challenges. The research utilizes a more powerful analytical framework that combines power sector reform theory and principal-agent theoretical lens to explore the experience of power sector reforms in Kenya and provides a deeper understanding of drivers of utility performance and reform impacts. Empirical findings show that the structural, governance and regulatory reforms that previously created incentives for improved utility performance are increasingly threatened by political influence. Kenya Power’s financial viability has deteriorated in recent years and the regulator has been undermined. One of our major conclusions is that when the relationship between the principal (government) and agent (utility) is well understood and the agent is properly incentivized, performance improvements are possible. However, when the government undermines or muddies those incentives through conflicting political interventions, performance improvements can be reversed.

Background: It has been demonstrated that pressotherapy used post-exercise (Po-E) can influence training performance, recovery, and physiological properties. This study examined the effec-tiveness of pressotherapy on these parameters. Methods: The systematic review and meta-analysis were performed according to PRISMA guidelines. A literature search of MEDLINE, PubMed, EBSCO, Web of Science, SPORTDiscus and ClinicalTrials has been done up to March 2021. Inclusion criteria were: randomized control trials (RCTs) or cross-over studies, mean participant age be-tween 18-65 yrs., ≥ 1 exercise mechanical pressotherapy intervention. The risk of bias was assessed by the Cochrane risk-of-bias tool for RCT (RoB 2.0). Results: 12 studies comprised of 322 partici-pants have been selected. The mean sample size was n = 25. Pressotherapy significantly reduce muscle soreness(Standard Mean Difference;SMD= -0.33; CI = -0.49, -0.18; p < 0.0001; I2 = 7%). Pres-sotherapy did not significantly affect jump height (SMD = -0.04; CI =-0.36, -0.29; p = 0.82). Presso-therapy did not significantly affect creatine kinase level 24-96h after DOMS induction (SMD = 0.41; CI = -0.07, 0.89; p = 0.09; I2 = 63%). Conclusions: Only moderate benefits of using pressotherapy as a recovery intervention have been observed. Results varied between the type of exercise and used protocol. Pressotherapy should only be applied as an additional component of a more compre-hensive recovery strategy. Study PROSPERO registration number- CRD42020189382.
Anomalous Ca-Content Dependence of Dielectric Property of Charge Ordered Pr1-xCaxMnO3 as a Signature of Charge-Ordered Phase Modulation
Authors: Mondal Partha Sarathi , Singh Ankit Kumar
Published: February 2022

Low temperature dielectric property of charge/orbital ordered manganite, Pr1-xCaxMnO3 for 0.40≤x≤0.50 is investigated systematically as a function of Ca-content, x. The Ca-content dependence of dielectric permittivity and dissipation factor exhibit distinct maxima around x=0.45. The overall dielectric response of charge ordered Pr1-xCaxMnO3 is dominated by polarization induced by polaron hopping and exhibits thermally activated relaxation behaviour. The dielectric relaxation behaviour over the investigated temperature range is analysed with the help of small polaron hopping model and as well as variable range hopping model. The estimated polaron parameters also display non-monotonic variation with x and exhibit broad minima between x=0.425-0.45. The observed results suggest that a modulation of checker board type charge ordering pattern in Pr1-xCaxMnO3 is possibly taking place in the Ca-content range of investigation 0.40≤x≤0.50.

Pentingnya pendidikan STEM telah diakui untuk mempersiapkan siswa yang beragam untuk menumbuhkan peluang kerja di STEM di masa depan, dan untuk sebuah bangsa secara keseluruhan untuk inovasi teknologi dan kemakmuran dan keamanan nasional (Li, Schoenfeld, Disessa. 2019). Pendekatan STEM membutuhkan model pembelajaran yang tepat untuk bisa mencapai tujuan pembelajaran. Salah satu model pembelajaran yang dapat digunakan dengan STEM yaitu PjBL (Project Based Learning). Project-Based Learning (PjBL) merupakan model pembelajaran yang mengajarkan konsep dalam kurikulum melalui sebuah proyek yang berpusat pada peserta didik agar dapat bekerja secara otonom, kolaboratif dan melalui tugas-tugas. STEM (Science, Technology, Engineering dan Mathematics) merupakan pembelajaran yang mengintegrasikan konsep-konsep sains, teknologi, engineering dan matematika. Siswa mampu menerapkan pengetahuan STEM secara praktis dan menghasilkan pembelajaran yang bermakna melalui kegiatan PjBL. Menggabungkan PjBL dengan STEM memiliki pengaruh dalam sikap siswa terhadap pengejaran karir masa depan (Tseng,Chang, Lou, Chen. 2013).

Objectives. To report findings from qualitative research that describe sources of hesitancy and barriers to vaccine uptake among lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) populations.

Methods. In March 2021, we conducted focus groups with members of the Los Angeles, California LGBTQIA community to identify barriers to becoming vaccinated. Semistructured interviews were conducted with 32 individuals in 5 focus groups. Thematic analysis was conducted to identify themes.

Results. Historical and ongoing medical trauma, including misgendering, and perceived emotional violence emerged as significant barriers to LGBTQIA individuals becoming vaccinated. Fear of violence was found to be a major barrier among transgender individuals, whereas fear of an unwelcoming vaccination site was a barrier for seniors. Finally, surviving was a higher priority than becoming vaccinated.

Conclusions. Participants reported vaccine hesitancy and barriers that are unique to the life experiences of LGBTQIA individuals; these include medical trauma, violence, stigma, and discrimination. Our findings highlight the need to include LGBTQIA leaders and trusted individuals in the development of vaccination education and the delivery of vaccination services.

Refugee and immigrant populations are extremely vulnerable to the consequences of the COVID-19 pandemic. COVID-19 vaccination is a critical tool in mitigating these consequences, but these same communities often lack access to COVID-19 vaccines. We describe the efforts of a community-based primary care clinic in Clarkston, Georgia to provide access to COVID-19 vaccines in a culturally sensitive manner to address this health disparity and vaccine hesitancy.

During the COVID-19 pandemic, media accounts emerged describing faith-based organizations (FBOs) working alongside health departments to support the COVID-19 response. In May 2021, the Department of Health and Human Services, Centers for Disease Control and Prevention, and the Association of State and Territorial Health Officials (ASTHO) sent an electronic survey to the 59 ASTHO member jurisdictions and four major US cities to assess state and territorial engagement with FBOs. Findings suggest that public health officials in many jurisdictions were able to work effectively with FBOs during the COVID-19 pandemic to provide essential education and mitigation tools to diverse communities.

The effect of climate change on cotton productivity - an empirical investigation in Pakistan
Authors: Arshad Muhammad Umer
Published: February 2022

Pakistan is the primary producer of cotton, which is an indispensable crop worldwide. The agriculture sector depends on the climate and may be susceptible to future climate changes, such as increasing temperature, heavy rainfall, droughts, and floods directly impacting cotton productivity. This study empirically investigates the relationship between climate change variables and non-climate change variables on cotton productivity in Pakistan. An econometric technique, the “autoregressive distributed lag model” (ARDL), was employed on time series data from 1970 to 2018 to explore the existence and nature of the relationship among variables. The findings indicated the presence of co-integration among variables which confirms the long-run relationship among the variables. At the same time, the empirical results revealed that increases in temperature and rainfall positively affected cotton productivity. However, CO2 harms cotton productivity. Moreover, infrastructural changes positively affect cotton productivity in both the long and short run, while labor is negatively related to productivity. The area, fertilizer, and seed consumption showed a significant positive effect on cotton productivity. We employed the dynamic ordinary least squares (OLS), co-integration regression estimation, and the series test to validate the robustness of the finding. The finding of this study urges policymakers to devise a comprehensive policy to mitigate the adverse effect of climate change and upsurge water conservation. Furthermore, it is imperative to adopt environmentally friendly production inputs and modern techniques, which helps to gain sustainable cotton productivity. To conclude, the cotton crop is significantly affected by climate change subject to the region. Although this study analyzed the Pakistan case, the model can be generalized to all the developing countries

Background: There is a considerable gap between care provision and the demand for care for common mental disorders in low-and-middle-income countries. Screening for these disorders, e.g., in primary care, will help to close this gap. However, appropriate norms and threshold values for screeners of common mental disorders are lacking. Methods: We gathered data on frequently used screeners for alcohol use disorders, depression, and anxiety disorders in a representative sample from Suriname, a non-Latin American Caribbean country. Results: We established cut-off values, normsNorms and crosswalk tables were established for the conversion of raw scores into a common metric: T-scores. Furthermore, recommended cut-off values on the T-score metric for severity levels were compared with international cut-off values for raw scores on these screeners. The appropriateness of these cut-offs and the value of converting raw scores into T-scores are discussed. Conclusion: Cut-off values help with screening and early detection of those who are likely to have a common mental health disorder and may require treatment. Conversion to a common metric simplifies the interpretation of test results.

Purpose: The purpose of this study was to investigate the surgical efficacy of crossing the cervicothoracic junction during posterior cervical laminectomy and fusion for the treatment of multilevel cervical ossification of the posterior longitudinal ligament (OPLL).Methods: From October 2009 to October 2017, 46 consecutive patients with multilevel cervical OPLL underwent posterior cervical laminectomy and crossing the cervicothoracic junction fusion were obtained in the study. Their medical records were retrospectively collected. Cervical lordosis and cervical sagittal balance were used to assess radiographic outcomes. Japanese Orthopedic Association (JOA), axial symptom, C5 root palsy, blood loss, and operation time were used to assess clinical outcomes. The mean follow-up period was 20.7± 8.3 months.Results: The operation time was 205.2 ± 39.8 minutes and the intraoperative blood loss was 352.2 ± 143.7 ml. Analysis of the final follow-up data showed significant differences in JOA score (P<0.01), C2-C7 lordosis angle (P<0.01), and C2-C7 SVA (P<0.01). CT confirmed that grafted bone was completely fused in all patients and progression of OPLL was observed in two patients(4.3%) at final follow-up. No adjacent segment disease (ASD) or instrument failure occurred in any patients.Conclusions: Cervical laminectomy and crossing the cervicothoracic junction fusion are effective and safe methods to treat multilevel cervical OPLL. Randomized controlled studies with long-term follow-up are needed to confirm these results.
