Simulation Game Outcomes: A Multilevel Examination of Knowledge Sharing Norms, Transactive Memory Systems, and Individual Learning Goal Orientations
Authors: Super Janice Francis , Betts Teresa K. , Keller Heath , Humphreys Joy Roach
Published: August 2020

Background. Because computer-based simulation games are widely used in university classrooms, it is important to investigate factors which can lead to effective student team performance and positive individual outcomes.

Aim. This correlational study aimed to examine the effects of knowledge sharing norms, transactive memory systems, and individual learning goal orientations on game outcomes.

Method. The setting for this study was an undergraduate logistics and supply chain class. The class uses a serious simulation game which is designed to realistically mimic the business transactions within an enterprise resource planning system (ERP). Cross-sectional surveys captured individual learning goal orientations. After multiple rounds of simulation game play, subsequent surveys captured student reactions, perceptions of knowledge sharing behaviors, and transactive memory systems.

Results. Two sets of analyses were conducted using a sample of 100 undergraduates performing in 42 teams. At the group-level, OLS regression results suggest that, while there was no effect on objective team performance, knowledge sharing norms enhanced perceptions of team performance, and this effect was mediated through the development of transactive memory systems. For individual-level outcomes, multilevel results suggest that knowledge sharing norms were positively related to satisfaction with the team, but not satisfaction with the task. However, transactive memory systems were positively related both satisfaction with the team and satisfaction with the task. Individual learning goal orientation was positively related to satisfaction with the task but not satisfaction with the team.

Conclusion. Our findings suggest that learning goal orientations and norms for knowledge sharing are linked to positive outcomes of team-based simulation game learning activities. Because learning goal orientations are malleable and norms for knowledge sharing can be encouraged, these factors are within the influence of the instructor. As such, they should be nurtured and developed through the active encouragement of experimentation, exploration, and communication between team members.

Authors: Kang Lin-Ju , Hsu Yu-Wei , Hwang Ai-Wen
Published: August 2020

The Chinese version of the Family-Professional Partnership Scale (FPPS-C) measures satisfaction with mutually established parent-professional partnerships. This study aimed to evaluate the measurement properties of the FPPS-C Family and Professional Versions. The participants comprised 167 parents who had a child enrolled in an early intervention program, and 200 early intervention professionals in Taiwan. Structural validity, internal consistency, test–retest reliability, and construct validity were examined. The Family Version denoted a single-dimensional scale with high internal consistency (α = .99) and adequate test–retest reliability (intraclass correlation coefficient [ICC] = 0.54). The Professional Version showed a three-factor structure with moderate to adequate internal consistency (α = .64–.90) and test–retest reliabilities (ICC = 0.60–0.77). Construct validity was evidenced through positive associations between parental and professional perceptions on partnerships and to family-centered service provision. The FPPS-C is a reliable and valid measure, and the study findings can influence research initiatives and practices that aim to ameliorate the provision of family-centered services by early intervention programs.
Variation Among Surgeons Regarding the Use of Preoperative Antibiotics in Percutaneous Pinning Procedures of the Upper Extremity in the Pediatric Population
Authors: Case Alexandria L. , Ty Jennifer M. , Chu Alice , Ho Christine A. , Bauer Andrea S. , Abzug Joshua M.
Published: August 2020

Background: Preoperative antibiotics may not be necessary, given the very low infection rates associated with percutaneous pinning (PP) procedures of the upper extremity (UE). The purpose of this study was to determine the patterns and variation surrounding the use of preoperative antibiotics when performing PP procedures of the child’s UE. Methods: A survey was sent to all members of Pediatric Orthopedic Society of North America to assess the use and opinions regarding preoperative antibiotics for PP procedures of the UE. Queries included the surgeon’s current practice and thoughts regarding the need for preoperative antibiotics based on the anatomical location of the procedure. Results: Eight-one percent of the 295 respondents routinely order preoperative antibiotics for all PP procedures of the UE; however, only 60% felt that all patients must receive preoperative antibiotics. The requirement for preoperative antibiotics varied based on the anatomical location—81% for shoulder, 70% for elbow, 66% for wrist, and 62% for hand/finger. Canadian surgeons were significantly less likely to believe that preoperative antibiotics must be used in all UE cases, all shoulder cases, and all elbow cases (all Ps = .04). Conclusion: The vast majority (81%) of surgeons surveyed routinely prescribe antibiotics for PP procedures of the UE despite the fact that 40% of surgeons felt that antibiotics were not necessary for all procedures. As the PP procedure is performed more distally on the UE, fewer surgeons feel preoperative antibiotics are necessary. Future studies assessing infection rates with and without the use of preoperative antibiotics are necessary to determine the true need for these medications.

Published: August 2020

Characteristics that contribute to successful redesign and launch of principal preparation programs may be understood collectively as the capacity of those programs. A model of capacity for redesign of principal preparation programs should strike a balance between the technical and professional aspects of teaching and leadership and the cultural and relational aspects of organizations. We surveyed a national sample of program directors and interviewed a purposive sample of those in the midst of redesigning their programs to arrive at a framework of the tools and raw materials programs need to meet the new demands of principal preparation.
Suicidal and non-suicidal self-injurious behaviour in patients with bipolar disorder and comorbid attention deficit hyperactivity disorder after initiation of central stimulant treatment: a mirror-image study based on the LiSIE retrospective cohort
Authors: Öhlund Louise , Ott Michael , Lundqvist Robert , Sandlund Mikael , Salander Renberg Ellinor , Werneke Ursula
Published: August 2020

Background:

Currently, our understanding regarding treatment of adult attention deficit hyperactivity disorder (ADHD) co-occurring with bipolar disorder (BD) remains limited. The aim of this study was to evaluate the impact of central stimulant (CS) treatment on suicidal and non-suicidal self-injurious behaviour in patients with a pre-existing diagnosis of BD or schizoaffective disorder (SZD). Specifically, we tested the hypothesis that CS treatment significantly decreased the number of suicide attempts and non-suicidal self-injury events.

Methods:

A mirror-image study in patients with a dual diagnosis of BD or SZD and ADHD, comparing suicide attempts and non-suicidal self-injury events within 6 months and 2 years before and after CS initiation. This study was part of a retrospective cohort study (LiSIE) into effects and side-effects of lithium for maintenance treatment of BD as compared with other mood stabilisers.

Results:

Of 1564 eligible patients, 206 patients met the inclusion criteria. Within the 6 months after CS initiation, suicide attempts and non-suicidal self-injury events decreased significantly, both in terms of numbers of patients having such events ( p = 0.013) and numbers of events experienced ( p = 0.004). These effects were preserved 2 years after CS initiation.

Conclusions:

CS treatment may reduce the risk of suicide attempts and non-suicidal self-injury events in patients with a dual diagnosis of BD or SZD and ADHD. Based on our findings, clinicians should not withhold CS treatment from patients with concomitant ADHD for fear of deterioration of the underlying BD. However, to minimise the risk of manic episodes concomitant mood stabiliser treatment and close monitoring remains warranted.
Exploring new teachers conceptualizations of critical simulations in world history, American history, and economics learning experiences
Authors: Magill Kevin Russel , Shanks Neil
Published: August 2020

In this study we examine early career social studies teachers’ use and understanding of critical simulations. We began work with participants as teacher candidates in their pre-service programs and formally studied them as they began their in-service teaching. We were particularly interested in teacher efforts to use simulation to facilitate a more critical disciplinary consciousness. Data indicate that participant teachers utilized simulations to: enhance students’ ability to critically engage with social studies content, facilitate more democratic dialogue, and critique normalized systems of power. We do not suggest that simulations in and of themselves are “critical,” rather, we argue they can be an effective means of providing a safe environment for considering the complexities of certain issues in social studies. Furthermore, we argue critical social studies teachers and teacher educators can be purposeful in their use of simulation to avoid enshrining the status quo. Finally simulations can help critical teachers illuminate oppression and facilitate a more humanizing vision within the social studies if they possess critical consciousness, strong pedagogical content knowledge and a command of the method.

Published: August 2020

Background

Human T-cell lymphotropic virus (HTLV) remains a major safety concern for blood supplies. Despite many HTLV positive cases being reported in southeastern China, the detection of HTLV has not been prioritized in routine blood screening. Additionally, data on the prevalence of HTLV infection among blood donors is also limited. The objective of this study was to investigate the prevalence of HTLV among blood donors in three Chinese provinces through their representative blood centers, to evaluate the feasibility of chemiluminescence immunoassay (CLIA) for blood screening.

Methods

From November 2018 to March 2019, blood plasma samples were collected from Hebei, Changsha, and Shenzhen blood centers and were screened for the HTLV-1/2 antibody using a CLIA and enzyme-linked immunosorbent assay (ELISA). This was followed by confirmatory tests using INNO-LIA HTLV I/II.

Results

A total of 59,929 blood donations were collected and screened for HTLV-1/2. The reactive rate of CLIA and ELISA among donations in the Shenzhen blood center (0.0943%, 27/28,621) was higher than Hebei (0.0248%, 4/16,144), and Changsha (0.0198%, 3/15,164) (p < 0.05). After confirmation, 3 samples were confirmed as indeterminate for HTLV antibodies, and only one sample from the Shenzhen blood center was confirmed as HTLV-1. The overall prevalence of HTLV-1/2 was 1.67 per 100,000 (1/59,929). The HTLV-infected blood came from a 32-year-old first-time female donor with a high school degree, who belonged to the SHE ethnic minority and was born in the Fujian province.

Conclusions

In summary, the overall prevalence of HTLV-1/2 among blood donors in the three blood centers in China remains relatively low. However, blood donations with positive or indeterminate results for HTLV antibodies reminded us of the importance of HTLV screening among blood donors in China.

Published: August 2020

Background

The 3D8 single chain variable fragment (scFv) is a mini-antibody sequence that exhibits independent nuclease activity against all types of nucleic acids. In this research, crossing a 3D8 scFv G1 transgenic rooster with wild-type hens produced 3D8 scFv G2 transgenic chickens to evaluate suppression of viral transmission.

Result

The transgenic chickens were identified using genomic PCR and immunohistochemistry. To evaluate Newcastle disease virus (NDV) protection conferred by 3D8 scFv expression, transgenic, non-transgenic, and specific pathogen-free (SPF) chickens were challenged with virulent NDV by direct injection or aerosol exposure. The three groups of chickens showed no significant differences (p < 0.05) in mean death time after being directly challenged with NDV; however, in contrast to chickens in the non-transgenic and SPF groups, chickens in the transgenic group survived after aerosol exposure. Although the transgenic chickens did not survive after direct challenge, we found that the chickens expressing the 3D8 scFv survived aerosol exposure to NDV.

Conclusions

Our finding suggest that the 3D8 scFv could be a useful tool to prevent chickens from spreading NDV and control virus transmission.
Immediate effects of cervicothoracic junction mobilization versus thoracic manipulation on the range of motion and pain in mechanical neck pain with cervicothoracic junction dysfunction: a pilot randomized controlled trial
Authors: Joshi Shriya , Balthillaya Ganesh , Neelapala Y. V. Raghava
Published: August 2020

Background

Cervicothoracic (CT) junction hypomobility has been proposed as a contributing factor for neck pain. However, there are limited studies that compared the effect of CT junction mobilization against an effective intervention in neck pain. Thoracic spine manipulation is a nonspecific intervention for neck pain where remote spinal segments are treated based on the concept of regional interdependence. The effectiveness of segment-specific spinal mobilization in the cervical spine has been researched in the last few years, and no definite conclusions could be made from the previous studies. The above reasons warrant the investigation of the effects of a specific CT junction mobilization against a nonspecific thoracic manipulation intervention in neck pain. The present study aims to compare the immediate effects of C7-T1 Maitland mobilization with thoracic manipulation in individuals with mechanical neck pain presenting with CT junction dysfunction specifically.

Methods

A randomized clinical trial is conducted where participants with complaints of mechanical neck pain and CT junction dysfunction randomly assigned to either C7-T1 level Maitland mobilization group or mid-thoracic (T3-T6) manipulation group (active control group). In both the groups, the post graduate student (SJ) pursuing Master’s in orthopedic physiotherapy delivered the intervention. The outcomes of cervical flexion, extension, side flexion & rotation range of motion (ROM) were measured before & after the intervention with a cervical range of motion (CROM) device. Self-reported pain intensity was measured with the numerical pain rating scale (NPRS). The post-intervention between-group comparison was performed using a one-way ANCOVA test.

Results

Forty-two participants with mean age CT junction group: 35.14 ± 10.13 and Thoracic manipulation group: 38.47 ± 11.47 were recruited for the study. No significant differences in the post-intervention baseline adjusted outcomes of cervical ROM & self-reported pain intensity were identified between the groups after the treatment (p = 0.08, 0.95, 0.01, 0.39, 0.29, 0.27for flexion, extension, bilateral lateral flexion & rotations respectively) & neck pain intensity (p = 0.68). However, within-group, pre, and post comparison showed significant improvements in cervical ROM and pain in both groups.

Conclusion

This preliminary study identified that CT junction mobilization is not superior to thoracic manipulation on the outcomes of cervical ROM and neck pain when level-specific CT junction mobilization was compared with remote mid-thoracic manipulation in individuals with mechanical neck pain and CT junction dysfunction.

Published: August 2020

We analyse social demography, livelihood diversification and land tenure among the Maasai people inhabiting Kenya (three sites) and Tanzania (one site) with contrasting land tenure policies. In Kenya, land was communally owned in the rural Amboseli, fully privatized in the peri-urban Kitengela in Athi-Kaputiei and partially privatized and communally owned in the rural Maasai Mara. In Tanzania, the government owned the land but granted user rights to local villages in rural Simanjiro in Tarangire-Manyara. We interviewed 100 households per site from May to July 2006. There were regional distinctions in social demography, livelihood diversification, hiring herding labour and settlement arrangements, portraying differential transition away from traditional pastoral Maasai society. The transition is most advanced in Kitengela located near Nairobi City, where privatization of land tenure in the 1980s triggered land sub-division, unprecedented land fragmentation and large-scale collapse of the commons, pastoralism and conservation. Land privatization and sub-division in Maasai Mara and Amboseli started in 2000s and were followed similarly by unprecedented fragmentation through fences and accelerated collapse of the commons, pastoralism and conservation, except where wildlife conservancies were later established. We found several differences at the household, regional and national levels. The average age of household heads was lower in Maasai Mara and Amboseli than in Kitengela and Simanjiro. The average number of wives per male household head was lowest in Kitengela, intermediate in Mara and Amboseli and highest in Simanjiro. Correspondingly, the mean number of children per family was lowest in Kitengela, intermediate in Mara and Amboseli and highest in Simanjiro. Household heads were more educated closer to urban centres. Household heads without formal education were thus most common in Amboseli, intermediate in Mara and Simanjiro and fewest in Kitengela. Livelihood diversification was marked in all the sites. Notably, cultivation was widespread and most of those interviewed were interested in crop cultivation. The average number of acres cultivated per household was far higher in Simanjiro than in all the other sites. The mean number of hired herders per household was higher in Kitengela, with the highest number of children enrolled in schools, than in the Mara, Amboseli or Simanjiro. The average number of households per settlement was highest in the Mara, intermediate in Amboseli and Simanjiro and lowest in Kitengela. The marked regional variation in social demography, livelihood diversification and land tenurial arrangements reflects underlying variation in proximity to urban centres, agro-climatological and national developmental and policy environments.

Published: August 2020

Background

Protective mechanical ventilation (MV) aims at limiting global lung deformation and has been associated with better clinical outcomes in acute respiratory distress syndrome (ARDS) patients. In ARDS lungs without MV support, the mechanisms and evolution of lung tissue deformation remain understudied. In this work, we quantify the progression and heterogeneity of regional strain in injured lungs under spontaneous breathing and under MV.

Methods

Lung injury was induced by lung lavage in murine subjects, followed by 3 h of spontaneous breathing (SB-group) or 3 h of lowVtmechanical ventilation (MV-group). Micro-CT images were acquired in all subjects at the beginning and at the end of the ventilation stage following induction of lung injury. Regional strain, strain progression and strain heterogeneity were computed from image-based biomechanical analysis. Three-dimensional regional strain maps were constructed, from which a region-of-interest (ROI) analysis was performed for the regional strain, the strain progression, and the strain heterogeneity.

Results

After 3 h of ventilation, regional strain levels were significantly higher in 43.7% of the ROIs in the SB-group. Significant increase in regional strain was found in 1.2% of the ROIs in the MV-group. Progression of regional strain was found in 100% of the ROIs in the SB-group, whereas the MV-group displayed strain progression in 1.2% of the ROIs. Progression in regional strain heterogeneity was found in 23.4% of the ROIs in the SB-group, while the MV-group resulted in 4.7% of the ROIs showing significant changes. Deformation progression is concurrent with an increase of non-aerated compartment in SB-group (from 13.3% ± 1.6% to 37.5% ± 3.1%), being higher in ventral regions of the lung.

Conclusions

Spontaneous breathing in lung injury promotes regional strain and strain heterogeneity progression. In contrast, lowVtMV prevents regional strain and heterogeneity progression in injured lungs.

Werner Sollors is one of the first scholars of American literature to focus on African American literature before it was thought to constitute a canon in the academy. Unlike many other scholars who shared his focus, he completed his education in postwar Germany. The title of his doctoral dissertation on LeRoi Jones (Amiri Baraka), completed at the Free University of Berlin in 1975, has a still-contemporary ring: “The Quest for a ‘Populist Modernism.’” He taught at Columbia University, received a Guggenheim fellowship, and spent the bulk of his career in the United States. In this interview he discusses his intellectual formation and offers reflections on the development of his field, the evolving institutional culture of the university, and 1970s-era multiculturalism.
Falling through the cracks: a case study of how a timely integrated approach can reverse frailty
Authors: Freer Karen
Published: August 2020

The article ‘Social frailty: the importance of social and environmental factors in predicting frailty in older adults’ published in the British Journal of Community Nursing in 2019 reviewed the concept and models of frailty and how the role of social and environmental circumstances interplay. To better inform interventions within the community, the impact of social isolation and environmental disorder on frailty and the wellbeing of an individual patient are further explored. This paper describes the case of a 76-year-old man, Tommy, who was living with frailty and how an individualised care plan was undertaken, evidencing the positive effects that an integrated approach from health, social care, housing and the voluntary sector can offer. Multifaceted interventions are described, which were used to reverse frailty and change Tommy's future for the better.

Published: August 2020

Mesonychium asteria (Smith) is a cleptoparasitic bee with occurrence restricted to South America. In this study, we provide new information related to the host association and cleptoparasitic behavior of this species in nests of Centris xanthomelaena Moure & Castro. Observations were conducted at the nesting sites of C. xanthomelaena in a Caatinga area of Pernambuco state, Brazil. Females of M. asteria were observed performing overflying in nest aggregations and attacking some nests. We have confirmed the cleptoparasitic association with the emergence of adult M. asteria from the host bee nests, and also by the presence of its larva on the brood cells.

Published: August 2020

The present study was developed aiming to evaluate the richness and biogeography of social wasp species in the Brazilian savanna, Cerrado. In order to do so, we gathered data from specialized literature and field samplings performed at Sempre-Vivas National Park, northeastern Minas Gerais state. 18 genera and 137 species were recorded, with 4 endemic species of the Mischocytiarus genus. The results showed that Cerrado houses 40% of Brazilian Polistinae fauna and that Sempre-Vivas National Park is responsible for around 29% of this value, which makes it an important refuge for conservation of social wasps from Cerrado, as well as Mato Grosso state, due to its large number of restricted occurrence and endemic species. Nonetheless, there are Brazilian states and conservation units still lacking information for the taxon, making a bigger sampling effort in the Cerrado biome necessary, as it has been rapidly deteriorating due to human action.

In the proposed structure, we have taken advantage of the air holes surrounding the defect region to optimize the resonance characteristics so as to detect the target gas, which is required for designing miniaturized spectroscopic gas sensors. By fine-tuning the structural parameters of several ring air holes surrounding the defect region, the results show that the sensitivity can be up to 3303 nm/RIU, along with a high

Seroprevalence of brucellosis in sheep and goats in the Arabian Gulf region
Authors: Ebid M. , El Mola A. , Salib F.
Published: August 2020

Background and Aim: Brucellosis is a zoonosis that occurs worldwide. There were more efforts to control brucellosis in all countries. This study was performed to determine the seroprevalence of brucellosis in sheep and goats in some areas in the Arabian Gulf. Materials and Methods: The study analyzed 8500 sera from non-vaccinated sheep and goats. Animals included 6441 sheep (3420 from farms and 3021 from quarantine) and 2059 goats (1580 from farms and 479 from quarantine). Sera were tested using the Rose Bengal Plate Test (RBPT) and confirmed with an indirect enzyme-linked immunosorbent assay (i-ELISA) test. Final confirmation analyzed blood samples from confirmed infected animals (n=30, 23 sheep and seven goats) using polymerase chain reaction (PCR) and culture. Results: The serological examination showed that 62/8500 of animals (0.729%, confidence interval [CI] 95% 0.57-0.94) were seropositive for brucellosis. Thirteen of 5000 (0.26%, CI 95% 0.15-0.45) and 49/3500 (1.4%, CI 95% 1.1-1.8) of animals from farms and quarantine were seropositive, respectively. Out of the 6441, 46 (0.71%) sheep and 16/2059 (0.78%) goats were seropositive. i-ELISA confirmed 41/62 RBPT-positive animals – 41/8500 (0.482%, CI 95% 0.36-0.65). Eight of 5000 of these animals (0.16%, CI 95% 0.08-0.32) and 33/3500 (0.94%, CI 95% 0.67-1.3) were confirmed positive in farms and quarantine, respectively. Thirty of 6441 (0.466%) and 11/2059 (0.534%) cases were positive in sheep and goats, respectively. PCR confirmed 18 of 41 positive animals (0.212% of all sera, CI 95% 0.13-0.34) identified by both RBPT and i-ELISA. Three of 5000 (0.06%, CI 95% 0.019-0.19) and 15/3500 (0.429%, CI 95% 0.26-0.71) from farms and quarantine were confirmed positive. Tissue samples (uterine, supra-mammary, testicular, and accessory glands lymph node) were collected from positive animals, as detected by RBPT and i-ELISA, at culling or slaughtering. Using in vitro culture, 14/30 were confirmed positive – 3/7 from farms (two sheep and one goat) and 11/23 from quarantine (nine sheep and two goats). Biovar 1 was dominant. PCR confirmed 23/30 tissue samples, 4/7 from farms (three sheep and one goat), and 19/23 from quarantine (15 sheep and four goats). Conclusion: The overall brucellosis rate in sheep and goats is 0.48%, with fewer animals from farms testing positive (0.16%) in this area of the Arabian Gulf. The infection appears to be well controlled, and continuous effort is still needed to maintain control and completely eradicate brucellosis. Additional support is needed for testing and slaughterhouse monitoring. In quarantine (imported animals), brucellosis infection in the slaughterhouse (0.94%) could pose a risk for transmission and spread of infection. The effort is needed to monitor this threat, and PCR is a sensitive and time-saving test for brucellosis diagnosis. All 14 confirmed positive samples were Biovar 1 dominant.
“Yo soy aquel…” o la construcción del artista en el poema autorretrato modernista
Authors: Zuluaga Esnedy
Published: August 2020

El auge del poema autorretrato en el modernismo alcanzó con “Yo soy aquel…” de Darío el esplendor del “yo artista”. Bajo este dominio del “yo” el poeta empieza a incorporar cada vez más elementos de su cotidianidad artística en el texto. En la medida que se percata de su ensimismamiento en la torre de marfil se dirige al mundo, iniciando el largo encuentro del poeta con la expresión cotidiana desde su estatus de artista registrado decididamente en su obra. Los modernistas fueron los primeros en acercarse a las calles a las que los vanguardistas se entregaron en todo su afán de conquistarlas. Este hecho le permite al poeta modernista convertir su propia persona en motivo central mediante la composición de autorretratos. Este trabajo explora ese “yo artista” a partir de “Yo soy aquel…” como poema paradigmático del modernismo, que se describe en función de su creación, de su capacidad para proponerse en el centro de la construcción poética, de la figura del artista como ese “otro” que se configura en el poema autorretrato y que logra convertirse en el centro de la composición en la que triunfa el “yo poeta” perpetuado en el poema

Los compositores han depositado en sus textos, ideas o emociones y esto ha sido posible al uso de signos como en el lenguaje escrito. Es difícil pensar que las manipulaciones de los materiales musicales no alcanzan significado alguno quedando como un hecho carente de la participación afectiva del compositor. En los tratados de música, muy pocas veces se abre el espacio para dimensionar ampliamente nociones como la de texto musical, signo, estado afectivo, lenguaje y discurso. Por ello, apelo a la fuerza inventiva de la filosofía como disciplina para generar conceptos que proporcionen esquemas de pensamiento útiles para articular saberes provenientes de diferentes disciplinas que me lleven a responder las siguientes cuestiones: ¿De un texto musical, emerge significado alguno? ¿Un texto musical, acaso comunica?

Resumen:

El presente artículo procura, a partir del examen de dos blogs de literatura y crítica en español, rastrear los avatares de la crítica y “las trayectorias de la escritura como proceso” en el cruce entre cultura libresca y era digital. A partir de la lectura de No hay tal lugar de Cristina Rivera Garza (2002 y continúa) y Diario de lecturas de Vicente Luis Mora (2004 y continúa), el artículo rastrea los modos de aparición de la crítica en dos muy importantes blogs en particular, procurando una reflexión en torno a las páginas en línea de los escritores como lugares de intervención, como laboratorios de la propia escritura, como lugar de producción de enunciados provisorios, lugar de construcción de archivos de autor y como obras interactivas. Hacia el final del artículo, se examinan los modos de aparición de la tradición literaria en el presente: la reescritura de textos caros a la tradición de la modernidad, las pervivencias del canon, la vigencia en el siglo XXI de antiguos debates del campo.

El presente artículo medita sobre algunos particulares de la evolución que a lo largo de lo de los últimos decenios ha experimentado la grafomanía y con ella la crítica literaria al ser considerada como “fuente secundaria”. Además se pone en relación esta idea de crítica como literatura vicaria con el proceso saturación crítica contemporánea. Movimientos que, sin duda, han desplazado también la posición del crítico hacia zonas de indeterminación complicando el sentido final de la propia crítica literaria y su ubicación errática ya desplazada del eje central de reflexión sobre la literatura en la era digital

Sasak People’s Resistance Against Mataram-Karangasem and Dutch Colonial Rulers: The Role of Tuan Guru Umar Kelayu
Authors: Tohri Ahmad , Habibuddin H. , Rasyad Abdul
Published: August 2020

This article discusses the Sasak people’s resistance against MataramKarangasem and Dutch colonial rulers in the 19th century in Lombok, Indonesia. It particularly focuses on Tuan Guru Umar Kelayu and his central role in the emergence of Sasak people’s resistance which transformed into Sasak physical revolution local and global imperialismcolonialism. Using the historical method, this article collected data through observation, in-depth interviews, and documentation. The data analysis involved the historical methods of heuristics, verification or criticism, interpretation, and historiography. The findings show that Sasak people’s resistance was not only caused by economic factors but also related to other factors such as social, cultural, and religious ones. Tuan Guru Umar Kelayu played a key role in the Sasak people’s resistance in that it was under his leadership and influence that the resistance transformed into a physical struggle against MataramKarangasem and Dutch colonialism as seen in Sakra War and Praya War which were led by his students and friends.

Late-order terms of second order ODEs in terms of pre-factors
Authors: SAY Fatih
Published: August 2020

Factorial over a power approach is one of the fundamental techniques for deriving the late-order terms in the asymptotic approximation of integrals and differential equations. To our knowledge, although many differential equations depending on small or large parameters are addressed thoroughly and intensively by this approach in the literature to date, no explicit formula of the general representation of singularly-perturbed second order inhomogeneous ODEs in the form of this paper has yet been discussed generally in terms of their pre-factors. In this paper, we obtain a leading order asymptotic formula of the general asymptotic expansions suitable for the particular type of ODE by its pre-factors.

A APOLOGÉTICA CATÓLICA: COMBATER A CIÊNCIA MODERNA E (RE)VIVER A MEDIEVALIDADE
Authors: Borges Leonir , Vicençoni Daniel Longhini , Lima Aida Franco de
Published: August 2020

O contexto do nascimento da Ciência Moderna se dá na transição do feudalismo para o capitalismo. Neste período de mudanças, surgem diversos pensadores que se apresentam por caminhos distintos, porém, com o objetivo de se chegar à verdade, contrapondo-se ao pensamento predominante na época: o do catolicismo. Essa contraposição foi possível pela secularização da sociedade. Diante disso, o artigo de cunho bibliográfico apresenta brevemente os novos paradigmas da ciência moderna e, na sequência, a apologética católica frente à ciência moderna, como meio de manter sua hegemonia às formas de pensar e (re)viver a medievalidade

This paper describes the results of the study of the Mokhovsky coal mine undisturbed soils in different horizons of the soil profile. The study was conducted on the Sartakinskoe, Mokhovskoe and Karakanskoe fields. In each field the authors have determined the species composition of phytocenoses and soil types, and studied soil horizons and agrochemical characteristics (particle size and soil composition, humus content, hydrogen index, nutrient content, hydrolytic acidity, the amount of absorbed bases, absorption capacity, etc.). It has been established that the vegetation of the phytocenoses of the studied fields is represented by birch tree trunks with the inclusion of pine, sections of meadow and small fragments of steppe communities, where perennial herbaceous plants play a significant role, which is typical for temperate floras of the northern hemisphere. The results of the analysis of the structural and particle size distribution of the agrochemical characteristics of undisturbed soils in the Mokhovskoe, Sartakinskoe and Karakanskoe fields of the Mokhovsky coal mine indicate that these soils are of agronomic value, therefore it is recommended to remove and store the fertile layer from these sites with a view to their further use in biological reclamation to increase quality, productivity and environmental value of the restored lands in the Kemerovo Region. The fertile soil layer (PRP) and the potentially fertile soil layer (PRSP) from the Mokhovskoye field is recommended for forestry while the Sartakinskoe and Karakanskoe fields for agricultural restoration.
