Published: July 2020

El artículo analiza las percepciones de los estudiantes de Educación Secundaria Obligatoria (ESO) y Bachillerato sobre el uso de las Tecnologías de la Información y la Comunicación (TIC) en la enseñanza de la historia. La muestra participante fue de 467 estudiantes de Institutos de Educación Secundaria de la Región de Murcia. Este estudio forma parte de un proyecto de investigación de mayor envergadura, relativo a enseñanza de la historia e implantación de metodologías y recursos innovadores. Del cuestionario estructurado para la recogida de información, se han seleccionado los ítems relativos al uso de las TIC y a la visión de los discentes. Los resultados arrojan una persistencia del modelo tradicional de enseñanza, que no prioriza metodologías cooperativas y de indagación, en el cual las TIC siguen teniendo un papel subsidiario. Se conciben como un complemento, más esporádico aún en Bachillerato que en ESO. Las conclusiones determinan que mientras se siga enseñando historia con una visión factual y memorística es difícil formar ciudadanos críticos, con destrezas a la hora de construir su propio aprendizaje. Aunque el alumnado sea nativo digital será difícil que usen los recursos digitales para adquirir habilidades o valores, pues sigue priorizándose la transmisión pasiva de discursos cerrados.
The article analyzes the perceptions of students of Compulsory Secondary Education (ESO) and Baccalaureate about the use of Information and Communication Technologies (ICTs) in the teaching of history. The sample used was 467 students from public High Schools of the Region of Murcia and was part of a larger research, related to the teaching of history and the implementation of innovative methodologies and resources. The items related to the use of ICTs and their vision among students have been selected. The results show a persistence of the traditional teaching model, which does not prioritize cooperative and inquiry methodologies, in which ICTs continue to have a subsidiary role. They are a complement, more sporadic even in Baccalaureate than in ESO. While continuing to teach history with a factual and memorial vision, it is difficult to train critical citizens, with skills when it comes to building their own learning. Even if they are digital natives, it will be difficult for them to use digital resources to acquire skills or values, since passive transmission of closed speeches continues to be prioritized.

Can Total Joint Arthroplasty Be Safely Performed in Patients with Chronic Kidney Disease?
Authors: Sun Kai , Fan Meng , Jaing Wenxue 
Published: July 2020

Background
Patients suffering from chronic kidney disease are at greater risk of perioperative and postoperative complications. There is no systematic review study demonstrating whether total joint arthroplasty can be safely performed in patients with chronic kidney disease.

Methods
A literature search was performed in the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and Cochrane Library databases for information from the earliest date of data collection to September of 2018. Studies comparing the perioperative and postoperative outcomes of no–chronic kidney dysfunction (CKD) patients with those of CKD patients were included. Statistical heterogeneity was quantitatively evaluated by means of the χ2 test, with significance set at P < .10 or I2 > 50%.

Results
Three articles consisting of 38,209 patients were included (35,363 no-CKD patients and 2,846 CKD patients). The results showed that CKD was related to a greater increase in postoperative infection rate, deep vein thrombosis, readmission, and mortality (P < .1). No differences in length of surgery, length of stay, pulmonary embolism, or revision were observed (P > .10).

Conclusions
Compared with no-CKD patients, CKD patients demonstrated an increased risk of perioperative and postoperative complications.
The Infinite Playground
Authors: De Koven Bernard , Gramazio Holly 
Published: July 2020

A play-centered invitation to experience the power and delight unlocked by imagination.
Bernard De Koven (1941–2018) was a pioneering designer of games and theorist of fun. He studied games long before the field of game studies existed. For De Koven, games could not be reduced to artifacts and rules; they were about a sense of transcendent fun. This book, his last, is about the imagination: the imagination as a playground, a possibility space, and a gateway to wonder. The Infinite Playground extends a play-centered invitation to experience the power and delight unlocked by imagination. It offers a curriculum for playful learning.
De Koven guides the readers through a series of observations and techniques, interspersed with games. He begins with the fundamentals of play, and proceeds through the private imagination, the shared imagination, and imagining the world—observing, “the things we imagine can become the world.” Along the way, he reminisces about playing ping-pong with basketball great Bill Russell; begins the instructions for a game called Reception Line with “Mill around”; and introduces blathering games—Blather, Group Blather, Singing Blather, and The Blather Chorale—that allow the player's consciousness to meander freely.
Delivered during the last months of his life, The Infinite Playground has been painstakingly cowritten with Holly Gramazio, who worked together with coeditors Celia Pearce and Eric Zimmerman to complete the project as Bernie De Koven's illness made it impossible for him to continue writing. Other prominent game scholars and designers influenced by De Koven, including Katie Salen Tekinbaş, Jesper Juul, Frank Lantz, and members of Bernie's own family, contribute short interstitial essays.

Digital Entrepreneurship in Africa
Authors: Friederici Nicolas , Wahome Michel , Graham Mark 
Published: July 2020

The hope and hype about African digital entrepreneurship, contrasted with the reality on the ground in local ecosystems.
In recent years, Africa has seen a digital entrepreneurship boom, with hundreds of millions of dollars poured into tech cities, entrepreneurship trainings, coworking spaces, innovation prizes, and investment funds. Politicians and technologists have offered Silicon Valley–influenced narratives of boundless opportunity and exponential growth, in which internet-enabled entrepreneurship allows Africa to “leapfrog” developmental stages to take a leading role in the digital revolution. This book contrasts these aspirations with empirical research about what is actually happening on the ground. The authors find that although the digital revolution has empowered local entrepreneurs, it does not untether local economies from the continent's structural legacies.
Drawing on a five-year research project, the authors show how entrepreneurs creatively and productively adapt digital technologies to local markets rather than dreaming of global dominance, achieving sustainable businesses by scaling based on relationships and customizing digital platform business models for African infrastructure challenge. The authors examine African entrepreneurial ecosystems; show that African digital entrepreneurs have begun to form a new professional class, becoming part of a relatively exclusive cultural and economic elite; and discuss the impact of Silicon Valley's mythologies and expectations. Finally, they consider the implications of their findings and offer recommendations to policymakers and others.

Published: July 2020

Aims: The research was carried out to evaluate the agronomic performance of corn cultivars in contrasting phosphorus environments in the state of Pará, Brazil.
Study Design: The experimental design was randomized blocks with ten treatments and three replications. The treatments were composed of ten cultivars: AG 1051, AG 8088PRO2, BR 206, BRS 3046, PR 27D28, 2B655PW, AL BANDEIRANTE, ANHEMBI, CATIVERDE 02 and ORION
Place and Duration of Study: In the 2017/18 crop, two competition trials of corn cultivars were carried out at Sítio Vitória, municipality of Santa Maria das Barreiras, state Pará, Brazil.
Methodology: Two competition trials of corn (Zea mays L.) cultivars were carried out under contracting conditions of phosphorus: high P (100 kg ha-1 of P2O5) and low P (50 kg ha-1 of P2O5), using simple superphosphate (18% P2O5) as the source. The agronomic efficiency of phosphorus use was obtained by the difference between grain yield in both levels, divided by the difference between doses. The variables evaluated were: ear height, plant height, ear diameter, number of rows per year, number of grains per rows and grain yield.
Results: The mean grain yield of the cultivars ranged from 5,446 kg ha-1 (low P) to 11,486 kg ha-1 (high P), and the means of all cultivars were higher in high P. The means agronomic efficiency ranged from 25.1 kg kg-1 (AL BANDEIRANTE) to 96.6 kg kg-1 (AG 1051).
Conclusion: The highest phosphorus dose (100 kg ha-1 of P2O5) resulted in higher values in the variables studied. The cultivars that stood out the most, under high and low phosphorus, were AG 8088PRO2, AG 1051 and BRS 3046, the last two being agronomically efficient.

Background: Augmentation of postoperative analgesia with various adjuvants has become a standard in regional anesthesia. There are no studies about dexmedetomidine multiple approaches in supraclavicular brachial plexus block (BPB) was contrasted. We compare perineural dexmedetomidine and intravenous dexmedetomidine Bupivacaine as adjuvant in supraclavicular brachial plexus block.
Materials and Methods: This prospective randomized controlled double-blind study was conducted on 120 patients with age between 20 and 60 years, both sexes, scheduled for elective upper limb surgery. Patients were randomly allocated into 3 groups, 40 patients in each received plain bupivacaine 0.5% (20 ml) in supraclavicular BPB; group I (Control group): add 1 mL normal saline perineural, group II: Bupivacaine with perineural dexmedetomidine (BDP) add 1 μg.kg-1dexmedetomidine perineurally. group III: Bupivacaine with intravenous dexmedetomidine (BDV) add 0.5 μg.kg-1 dexmedetomidine in 50 mL of normal saline administered as infusion over 10 min. Onset and duration of sensory and motor blocks, hemodynamic variables, adverse effects, and duration of analgesia were assessed.
Results: Heart rate and mean arterial pressure was significantly decrease in group III &group II compared to group I were compared by ANOVA (F) test. onset of sensory &motor block was statistically significant shorter in group II compared to group I & III. Duration of sensory &motor block was statistically significant longer in group II compared to group I & III. there was statistically significant decrease VAS in group II were analysed using Kruskal-Wallis test between three groups. There was statistically significant increase RSS in group II & III. The first time of analgesic request was statistically significant prolonged in duration in group II.
Conclusion: Perineural dexmedetomidine (1 µg/ kg) as an adjuvant to bupivacaine is significantly high thanIV dexmedetomidine (0.5 µg/ kg) and bupivacaine alone in supraclavicular BPB as regards to the onset and the duration of sensory block, so Increasingpostoperative analgesia.

Del punitivismo carcelario a la matanza sistemática: El avance de los operativos militarizados en la era post-Chávez
Authors: Zubillaga Verónica , Hanson Rebecca 
Published: July 2020

Este ensayo, basado en dos investigaciones cualitativas en curso, plantea que para comprender el aumento reciente de las muertes violentas en Venezuela y específicamente en Caracas en el período post Chávez, tenemos que colocar en el centro del análisis los discursos y las prácticas de un actor privilegiado como lo es el Estado, en un contexto de colapso de los precios petroleros. Se propone que esta inusitada violencia letal puede ser comprendida por el impacto que ha ocasionado, dentro del histórico proceso de militarización de la seguridad ciudadana, un punitivismo carcelario que con el pasar de los años ha venido abriendo el paso y yuxtaponiéndose a una práctica de matanza sistemática extralegal implicada en la extrema violencia policial y militar de operativos militarizados focalizados en los sectores pobres. Esta avanzada militar, se puede decir, forma parte del avance de una necropolítica en el país en tiempos de Revolución Bolivariana post-Chavista.

Published: July 2020

Abstract

Objectives
Overwork has been recognized as a risk factor for cerebrovascular and cardiovascular disease (CCVD). To our best knowledge, Japan is the first country in the world to implement an independent act (the 2014 Act) for the prevention of overwork-related disease, which was promoted through application of preventive measures, such as reductions in working hours. We assessed changes in working hours and overwork-related CCVD before and after introduction of the 2014 Act.

Methods
We calculated the overwork-related CCVD incidence rate and average monthly working hours for 10 industry groups in Japan with data from 2012 to 2018. We applied a causal mediation analysis to estimate the total effect of implementing the 2014 Act on the overwork-related CCVD and the effect mediated by working hours.

Results
An average of 271 for every 48 million employees developed overwork-related CCVD per year. After introducing the 2014 Act, the incidence rate ratio of overwork-related CCVD was 0.881-fold lower (95% CI 0.780-0.995) compared with before the policy change. The 2014 Act contributed to a decrease of 26% (78 cases per year; 95% CI 29-173) of the overwork-related CCVD incidence per year. Approximately 41% (32 cases per year) of this effect could be explained by reduced working hours.

Conclusions
Our study highlights the impact of the 2014 Act in Japan on the reduction in working hours, which further contributes to the reduction in overwork-related CCVD. Policymakers should consider adopting our innovative approach to assess the mediation effect underlying the implementation of new policies.
A moderated mediation analysis of occupational stress, presenteeism, and turnover intention among occupational therapists in Korea
Authors: Chun Byung-Yoon , Song Chiang-Soon 
Published: July 2020

Abstract

Objectives
Presenteeism is undoubtedly a widespread phenomenon in organizations. Research on presenteeism has been conducted for decades in the broader workforce (eg, nurses, doctors, teachers, police officers). Occupational stress and turnover intention in occupational therapy have been extensively studied. However, the effect of presenteeism on the relationship between occupational stress and resultant turnover intention among occupational therapists is unclear. This study aims to explore the mediating effect of presenteeism and moderating effect of perceived organizational support in the relationship between occupational stress and turnover intention among occupational therapists in Korea.

Methods
We conducted an individual and cross-sectional analysis of 257 occupational therapists from various health care institutions in Korea. Data were collected and hypotheses were tested via Process macro. Quantitative analyses were conducted with SPSS 26 and LISREL 8.54.

Results
Occupational stress was strongly related to presenteeism, which in turn predicted turnover intention. Presenteeism played a mediating role between occupational stress and turnover intention. Moreover, occupational therapists’ perception of organizational support acted as an important mechanism through which presenteeism mediated the relationship between occupational stress and turnover intention.

Conclusions
This study highlights the need to maximize employee productivity and retain talent by providing managers with insight into the mechanism of presenteeism in relation to occupational stress and turnover intention among occupational therapists in Korea.
