Valoración y uso de la plataforma Blackboard Collaborate en una universidad a distancia: estudio de caso sobre las prácticas declaradas de docentes del Grado de Psicología
Authors: Villalon Ruth , Luna María , Garcia-Barrera Alba
Published: February 2022

Los métodos de comunicación síncrona en los entornos virtuales de aprendizaje son una realidad cada vez más presente en la universidad. Sin embargo, aún no conocemos de forma sistemática cómo los profesores conciben estas tecnologías en la práctica. Este estudio tiene por objetivo explorar la práctica declarada de profesores de enseñanza superior con la plataforma Blackboard Collaborate. Con tal fin, se entrevistó individualmente a ocho docentes del Departamento de Psicología de una universidad a distancia. Se indagó acerca de su uso real, uso ideal y su valoración global de la plataforma. Los resultados indican que las profesoras emplean la plataforma Blackboard Collaborate con distintos objetivos y en diversos formatos, pero que en las prácticas más habituales prima más la transmisión de información que la construcción de conocimiento. Según el profesorado, el uso ideal de la videoconferencia implicaría aumentar el número de sesiones, fomentar la participación del alumnado, incrementar su dominio del contenido y cambiar el rol de docentes y discentes. A la hora de valorar la herramienta, las participantes tienen como marco de referencia la enseñanza cara a cara y apuntan en relación a ésta varias ventajas, pero también ciertas limitaciones. No obstante, su valoración global de Blackboard Collaborate es positiva. A partir de estos resultados se plantean implicaciones para la formación de los docentes y para el diseño de futuras investigaciones en estos entornos virtuales síncronos.

Uso de las Metodologías de Aprendizaje Colaborativo con TIC: Un análisis desde las creencias del profesorado
Authors: Acosta Corporan Rosalba , Martín García Antonio Víctor , Hernández Martín Azucena
Published: February 2022

El objetivo principal de este estudio es analizar las creencias de profesores de enseñanza media o bachillerato de la República Dominicana sobre la metodología basada en el aprendizaje colaborativo mediado por las TIC (CSCL). Se obtuvo una muestra de 542 docentes a los que se aplicó un cuestionario adaptado, compuesto por 33 ítems que miden diferentes aspectos relacionados con el proceso de enseñanza y aprendizaje en entornos de uso de CSCL. Los resultados ponen de manifiesto una alta valoración positiva sobre esta metodología por parte de los docentes, especialmente para mejorar su desarrollo profesional. No perciben, sin embargo, tantos beneficios al emplearla con los estudiantes, ya sea en la mejora del aprendizaje o del proceso de enseñanza en general. También se observan algunas diferencias entre los grupos en función básicamente de la variable años de experiencia docente. La sensibilización del profesorado sobre las ventajas de la metodología CSCL es una asignatura pendiente para la mejora de la calidad educativa; y ello exige el impulso de debates internos en las instituciones escolares por parte de las administraciones educativas, de modo que se promueva el uso de esta metodología en los procesos de enseñanza y aprendizaje y en el desarrollo profesional docente.
How to assess A meaningful technology-integrated tool for the reflective educators
Authors: Paiano Anna Paola , Annacontini Giuseppe
Published: February 2022

In this paper we intend to present a tool for self-assess, support and improve reflective thinking in the educators towards the use of digital storytelling. First, we present an overview on the theoretical framework for conceptualizing a reflective educator, who needs to have a conscious approach on the practice and inquiries on the ethical consideration and important outcomes of eductional practice, with self-reflection, deep analysis of personal beliefs, and expectations on men and women and potential in general, and on learning. Educators’ expectations are self-generating, and often hard to be changed. Moreover, educators stay trapped in unexamined rulings, judgements, interpretations, conventions, potentials and hopes. Second, we describe the process of constructing a DST for approaching to the reflective practice infusing personal beliefs and values into a professional identity. Third, we describe the process of constructing the rubric, its elements, indicators and levels to value the product every storyteller made. We conclude with the self-assessment tool we want to propose in our on-going research project.

Authors: Sangrà Boladeres Toni , López Rodríguez José Antonio , Iannitelli Muscolo Silvia
Published: February 2022

En este artículo se plantean las bases conceptuales y metodológicas de la asignatura de Rol e Identidad del Grado de Trabajo Social de la Universidad de Barcelona. El objetivo principal del artículo es realizar un paseo reflexivo conceptual, en torno a la propuesta pedagógica y teórica de la asignatura, que pueda ser de interés tanto para los y las estudiantes de Trabajo Social como para los y las profesionales. Por ello, el artículo está configurado de forma ensayística, para favorecer la argumentación y la exposición teórico-reflexiva derivada de las experiencias, conocimientos y aprendizajes de los y las docentes que han formado parte de esta asignatura. Este recorrido teórico de la asignatura se aborda desde dos dimensiones: la dimensión ontológica del contenido del plan docente y la dimensión epistemológica de la metodología educativa. De este modo, se refleja la necesidad de los y las estudiantes de Trabajo Social de compenetrarse con la complejidad para la comprensión de su realidad personal y profesional, y sitúa la narrativa (auto)biográfica como la estrategia que permite al estudiante pensar, pensarse y (re)pensarse como sujeto, y al mismo tiempo (re)construir esta complejidad.
Mujeres transformando el espacio público de Sant Roc.
Authors: Prat Bau Núria , Simó Gil Núria
Published: February 2022

Se presenta un estudio de caso único sobre una experiencia de Trabajo Social comunitario focalizado en la mejora del espacio público desarrollado por “Dones i Barri en xarxa”, un grupo de mujeres organizadas en un barrio periférico multicultural cuyo tejido social es débil, y con un uso intensivo y conflictivo del espacio público. Esta práctica acompañada por una trabajadora social tiene el encargo de apoyar un proceso de fortalecimiento colectivo para activar la participación vecinal. Para ello, se aplican técnicas vinculadas a las metodologías de Investigación-Acción-Participativa como, por ejemplo, el mapeo colectivo y la encuesta participativa; las metodologías artísticas colaborativas, con técnicas de arte público efímero y “arpilleras”. Y las metodologías de educación popular como los círculos de aprendizaje colectivo y las líneas histórico-temporales. En este texto se describen estas técnicas que en diferentes grados, modos e intensidades permiten un desarrollo integrado, dinámico y fluido entre la dimensión educativa, social y política para un Trabajo Social comunitario emancipador. Los resultados indican que los principales aportes de estas técnicas son: 1. Un enfoque educativo que proporciona autoconfianza y una mayor centralidad en ellas mismas. 2. Una mayor organización social del grupo, que favorece el co-liderazgo y la apropiación de la acción-reflexión, que les permite transitar de la indignación a la construcción de un proyecto de acción colectivo 3. Aumenta la visibilidad pública de las mujeres favoreciendo un posicionamiento político más situado que impacta tanto en sus redes cercanas, como en el rol comunitario del compromiso vecinal con el barrio.
Quantitative endoscopic photoacoustic tomography using a convolutional neural network
Authors: Zheng Sun , Meng Qi , Wang Xin-Yu
Published: February 2022

Endoscopic photoacoustic tomography (EPAT) is a catheter-based hybrid imaging modality capable of providing structural and functional information of biological luminal structures, such as coronary arterial vessels and the digestive tract. The recovery of the optical properties of the imaged tissue from acoustic measurements achieved by optical inversion is essential for implementing quantitative EPAT (qEPAT). In this paper, a convolutional neural network (CNN) based on deep gradient descent is developed for qEPAT. The network enables the reconstruction of images representing the spatially varying absorption coefficient in cross-sections of the tubular structures from limited measurement data. The forward operator reflecting the mapping from the absorption coefficient to the optical deposition due to pulsed irradiation is embedded into the network training. The network parameters are optimized layer by layer through the deep gradient descent mechanism using the numerically simulated data. The operation processes of the forward operator and its adjoint operator are separated from the network training. The trained network outputs an image representing the distribution of absorption coefficients by inputting an image that represents the optical deposition. The method has been tested with computer-generated phantoms mimicking coronary arterial vessels containing various tissue types. Results suggest that the structural similarity of the images reconstructed by our method is increased by about 10% in comparison with the non-learning method based on error minimization in the case of the same measuring view.
The health benefits of volunteering at a free, weekly, 5 km event in the UK: A cross-sectional study of volunteers at parkrun
Authors: Haake Steve , Quirk Helen , Bullas Alice
Published: February 2022

This paper investigates the motives for first participating in parkrun and its impact for those who volunteered compared to those who did not volunteer. A cross-sectional survey was emailed to parkrun registrants, resulting in 60,680 survey returns from parkrun participants who self-identified as volunteers only (n = 681), runners/walkers who volunteered (n = 21,928) or runners/walkers who did not volunteer (38,071). Two survey questions were analysed in this paper: (1) their motives for first participating in parkrun as a volunteer or runner/walker; and (2) the perceived impact on their health and wellbeing. More than half of respondents were female and were predominantly from a white ethnic background. Compared to runners/walkers who volunteered, those who volunteered exclusively were older, more likely to be retired and more likely to be inactive at registration. Exclusive volunteers were motivated by wanting to give something back to the community (45.8%), to feel part of a community (26.1%), to help people (24.5%) or because they were unable to run (21.1%). Runners/walkers who volunteered were more likely to volunteer because they felt obliged to (49.3%). A large proportion of exclusive volunteers reported improvements to connections with others such as feeling part of a community (83.5%), the number of new people met (85.2%) and time spent with friends (45.2%). While mental and physical health were ranked low by volunteers as a motive (4.7% and 2.7% respectively), improvements were reported by 54.5 and 29.3% respectively. The data shows that volunteering at parkrun without participating as a runner or walker can deliver some of the components of the Five Ways to Wellbeing advocated by the NHS. The characteristics of parkrun (free, regular, local, accessible and optional) make it a viable social prescribing offer that can be used as a model for other community events seeking to attract volunteers.

By assessing plant species composition and distribution in biodiversity hotspots influenced by environmental gradients, we greatly advance our understanding of the local plant community and how environmental factors are affecting these communities. This is a proxy for determining how climate change influences plant communities in mountainous regions ("space-for-time" substitution). We evaluated plant species composition and distribution, and how and which environmental variables drive the plant communities in moist temperate zone of Manoor valley of Northwestern Himalaya, Pakistan. During four consecutive years (2015–2018), we sampled 30 sampling sites, measuring 21 environmental variables, and recording all plant species present in an altitudinal variable range of 1932–3168 m.a.s.l. We used different multivariate analyses to identify potential plant communities, and to evaluate the relative importance of each environmental variable in the species composition and distribution. Finally, we also evaluated diversity patterns, by comparing diversity indices and beta diversity processes. We found that (i) the moist temperate zone in this region can be divided in four different major plant communities; (ii) each plant community has a specific set of environmental drivers; (iii) there is a significant variation in plant species composition between communities, in which six species contributed most to the plant composition dissimilarity; (iv) there is a significant difference of the four diversity indices between communities; and (v) community structure is twice more influenced by the spatial turnover of species than by the species loss. Overall, we showed that altitudinal gradients offer an important range of different environmental variables, highlighting the existence of micro-climates that drive the structure and composition of plant species in each micro-region. Each plant community along the altitudinal gradient is influenced by a set of environmental variables, which lead to the presence of indicator species in each micro-region.

Published: February 2022

Broccoli (Brassica oleracea var. italica) is an important B. oleracea cultivar, with high economic and agronomic value. However, comparative genome analyses are still needed to clarify variation among cultivars and phylogenetic relationships within the family Brassicaceae. Herein, the complete chloroplast (cp) genome of broccoli was generated by Illumina sequencing platform to provide basic information for genetic studies and to establish phylogenetic relationships within Brassicaceae. The whole genome was 153,364 bp, including two inverted repeat (IR) regions of 26,197 bp each, separated by a small single copy (SSC) region of 17,834 bp and a large single copy (LSC) region of 83,136 bp. The total GC content of the entire chloroplast genome accounts for 36%, while the GC content in each region of SSC,LSC, and IR accounts for 29.1%, 34.15% and 42.35%, respectively. The genome harbored 133 genes, including 88 protein-coding genes, 37 tRNAs, and 8 rRNAs, with 17 duplicates in IRs. The most abundant amino acid was leucine and the least abundant was cysteine. Codon usage analyses revealed a bias for A/T-ending codons. A total of 35 repeat sequences and 92 simple sequence repeats were detected, and the SC-IR boundary regions were variable between the seven cp genomes. A phylogenetic analysis suggested that broccoli is closely related to Brassica oleracea var. italica MH388764.1, Brassica oleracea var. italica MH388765.1, and Brassica oleracea NC_0441167.1. Our results are expected to be useful for further species identification, population genetics analyses, and biological research on broccoli.
Screening and functional prediction of differentially expressed genes in walnut endocarp during hardening period based on deep neural network under agricultural internet of things

Published: February 2022

The deep neural network is used to establish a neural network model to solve the problems of low accuracy and poor accuracy of traditional algorithms in screening differentially expressed genes and function prediction during the walnut endocarp hardening stage. The paper walnut is used as the research object to analyze the biological information of paper walnut. The changes of lignin deposition during endocarp hardening from 50 days to 90 days are observed by microscope. Then, the Convolutional Neural Network (CNN) and Long and Short-term Memory (LSTM) network model are adopted to construct an expression gene screening and function prediction model. Then, the transcriptome and proteome sequencing and biological information of walnut endocarp samples at 50, 57, 78, and 90 days after flowering are analyzed and taken as the training data set of the CNN + LSTM model. The experimental results demonstrate that the endocarp of paper walnut began to harden at 57 days, and the endocarp tissue on the hardened inner side also began to stain. This indicates that the endocarp hardened laterally from outside to inside. The screening and prediction results show that the CNN + LSTM model’s highest accuracy can reach 0.9264. The Accuracy, Precision, Recall, and F1-score of the CNN + LSTM model are better than the traditional machine learning algorithm. Moreover, the Receiver Operating Curve (ROC) area enclosed by the CNN + LSTM model and coordinate axis is the largest, and the Area Under Curve (AUC) value is 0.9796. The comparison of ROC and AUC proves that the CNN + LSTM model is better than the traditional algorithm for screening differentially expressed genes and function prediction in the walnut endocarp hardening stage. Using deep learning to predict expressed genes’ function accurately can reduce the breeding cost and significantly improve the yield and quality of crops. This research provides scientific guidance for the scientific breeding of paper walnut.

Purpose

Early detection and classification of bone tumors in the proximal femur is crucial for their successful treatment. This study aimed to develop an artificial intelligence (AI) model to classify bone tumors in the proximal femur on plain radiographs.

Methods

Standard anteroposterior hip radiographs were obtained from a single tertiary referral center. A total of 538 femoral images were set for the AI model training, including 94 with malignant, 120 with benign, and 324 without tumors. The image data were pre-processed to be optimized for training of the deep learning model. The state-of-the-art convolutional neural network (CNN) algorithms were applied to pre-processed images to perform three-label classification (benign, malignant, or no tumor) on each femur. The performance of the CNN model was verified using fivefold cross-validation and was compared against that of four human doctors.

Results

The area under the receiver operating characteristic (AUROC) of the best performing CNN model for the three-label classification was 0.953 (95% confidence interval, 0.926–0.980). The diagnostic accuracy of the model (0.853) was significantly higher than that of the four doctors (0.794) (P = 0.001) and also that of each doctor individually (0.811, 0.796, 0.757, and 0.814, respectively) (P<0.05). The mean sensitivity, specificity, precision, and F1 score of the CNN models were 0.822, 0.912, 0.829, and 0.822, respectively, whereas the mean values of four doctors were 0.751, 0.889, 0.762, and 0.797, respectively.

Conclusions

The AI-based model demonstrated high performance in classifying the presence of bone tumors in the proximal femur on plain radiographs. Our findings suggest that AI-based technology can potentially reduce the misdiagnosis of doctors who are not specialists in musculoskeletal oncology.

Activating mutations in EGFR predict benefit from tyrosine kinase inhibitor therapy for patients with advanced non-small cell lung cancer. Directing patients to appropriate therapy depends on accurate and timely EGFR assessment in the molecular pathology laboratory. This article describes the analytical design, performance characteristics, and clinical implementation of an assay for the rapid detection of EGFR L858R and exon 19 deletion mutations. A droplet digital polymerase chain reaction (ddPCR) assay was implemented with probe hydrolysis-dependent signal detection. A mutation-specific probe was used to detect EGFR L858R. A loss of signal design was used to detect EGFR exon 19 deletion mutations. Analytical sensitivity was dependent on DNA input and was as low as 0.01% variant allele fraction for the EGFR L858R assay and 0.1% variant allele fraction for the EGFR exon 19 deletion assay. Correlation of 20 clinical specimens tested by ddPCR and next generation sequencing showed 100% concordance. ddPCR showed 53% clinical sensitivity in the detection of EGFR mutations in plasma cell-free DNA from patients with lung cancer. The median clinical turnaround time was 5 days for ddPCR compared to 13 days for next generation sequencing. The findings show that ddPCR is an accurate and rapid method for detecting EGFR mutations in patients with non-small cell lung cancer.

Authors: Bernardini Giulia , Litterscheid Sarah , Torsello Giovanni Battista , Torsello Giovanni Federico , Beropoulis Efthymios , Özdemir-van Brunschot Denise
Published: February 2022

Objectives

A growing number of abdominal aortic aneurysms with severe angulated neck anatomy is treated by endovascular means. However, contradictory early and late outcomes have been reported. Our review and outcome analysis attempted to evaluate the available literature and provide clinicians with a base for clinical implementation and future research.

Materials and methods

A systematic review of the literature was undertaken to identify the outcomes of endovascular aneurysm repair in patients with severe infrarenal neck angulation (SNA ≥ 60°) vs non-severe neck angulation (NSNA). Outcome measures included perioperative complications, type 1a endoleak, neck-related secondary procedures, stent graft migration, aneurysm rupture, increase (>5mm) in sac diameter, all-cause and aneurysm-related mortality (PROSPERO Nr.: CRD42021233253).

Results

Six observational studies reporting on 5981 patients (1457 with SNA and 4524 with NSNA) with a weighted mean follow-up period of 1.8 years were included. EVAR in SNA compared with NSNA was associated with a higher rate of type 1a endoleak at 30 days (4.0% vs 1.8%; p< 0.00001), at 1 year (2.8% vs 1.9%; p<0.03), at 2 years (4.9% vs 2.1%; p< 0.0002), at 3 years (5.6% vs 2.6%; p< 0.0001). The rate of neck-related secondary procedures was significantly higher at 1 year (6.6% vs 3.9%; p<0.05) and at 3 years (13.1% vs 9%; p<0.05). Graft migration, aneurysm sack increase, aneurysm rupture and all-cause mortality were not statistically different at mid-term.

Conclusions

The use of EVAR in severely angulated infrarenal aortic necks is associated with a high rate of early and mid-term complications. However, aortic related and all-causes mortality are not higher compared to patients with NSNA. Therefore, EVAR should be cautiously used in patients with SNA.
Factors influencing COVID-19 vaccine uptake among adults in Nigeria
Authors: Adedeji-Adenola Halimat , Olugbake Olubusola A. , Adeosun Shakirat A.
Published: February 2022

Background

Emerging variants of Coronavirus disease 2019 (COVID-19) has claimed over 3000 lives in Nigeria and vaccination remains a means of reducing the death toll. Despite ongoing efforts by the government to ensure COVID-19 vaccination of most residents to attain herd immunity, myths and beliefs have adversely shaped the perception of most Nigerians, challenging the uptake of COVID-19 vaccine. This study aimed to assess the factors influencing the awareness, perception, and willingness to receive COVID-19 vaccine among Nigerian adults.

Methods

A cross-sectional online nationwide study was conducted from April to June 2021 among Nigerian adult population using the snowballing method. Descriptive analysis was used to summarise the data. Univariate and multivariate analysis was used to identify the predictors of COVID-19 uptake among the respondents. A p value <0.05 was considered significant.

Results

A total of 1058 completed forms were analysed and 63.9% were females. The mean age was 40.8 years±12.2 years. Most of the respondents (740; 69.5%) had satisfactory awareness of the vaccination exercise. The media was the main source of information. Health workers reported higher level of awareness (aOR = 1.822, 95% CI: 1.388–2.524, p<0.001). Respondents that are Christians and Muslims had better awareness compared to the unaffiliated (aOR = 6.398, 95% CI: 1.918–21.338, P = 0.003) and (aOR = 7.595, 95% CI: 2.280–25.301, p<0.001) respectively. There is average score for perception statements (566; 53.2%) towards COVID-19 vaccination. Close to half of the respondents (44.2%) found the short period of COVID-19 production worrisome. Majority of the respondents were willing to get the vaccine (856; 80.9%). Those without a prior diagnosis of COVID-19 had a lower willingness to get vaccinated (aOR = 0.210 (95% CI: 0.082–0.536) P = 0.001).

Conclusion

The study revealed a high level of awareness, willingness to receive the vaccine and moderate perception towards the vaccination activities. Influencing factors that significantly affects awareness were religion, occupation, education and prior diagnosis of COVID-19; for perception and willingness—occupation, and prior diagnosis of the COVID-19 were influencing factors.
Major ambulatory surgery among US adults with inflammatory bowel disease, 2017
Authors: Xu Fang , Wheaton Anne G. , Liu Yong , Greenlund Kurt J.
Published: February 2022

Background

Patients with inflammatory bowel disease (IBD) have higher health services use than those without IBD. We investigated patient and hospital characteristics of major ambulatory surgery encounters for Crohn’s disease (CD) or ulcerative colitis (UC) vs non-IBD patients.

Methods

We conducted a cross-sectional study using 2017 Nationwide Ambulatory Surgery Sample.

Major ambulatory surgery encounters among patients aged ≥18 years with CD (n = 20,635) or UC (n = 9,894) were compared to 9.4 million encounters among non-IBD patients. Weighted percentages of patient characteristics (age, sex, median household income, primary payers, patient location, selected comorbidities, discharge destination, type of surgeries) and hospital-related characteristics (hospital size, ownership, location and teaching status, region) were compared by IBD status (CD, UC, and no IBD). Linear regression was used to estimate mean total charges, controlling for these characteristics.

Results

Compared with non-IBD patients, IBD patients were more likely to have private insurance, reside in urban areas and higher income zip codes, and undergo surgeries in hospitals that were private not-for-profit, urban teaching, and in the Northeast. Gastrointestinal surgeries were more common among IBD patients. Some comorbidities associated with increased risk of surgical complications were more prevalent among IBD patients. Total charges were 9% lower for CD patients aged <65 years (Median: $16,462 vs $18,106) and 6% higher for UC patients aged ≥65 years (Median: $16,909 vs $15,218) compared to their non-IBD patient counterparts.

Conclusions

Differences in characteristics of major ambulatory surgery encounters by IBD status may identify opportunities for efficient resource allocation and positive surgical outcomes among IBD patients.
PROSPECTS FOR THE TERRITORIAL DEVELOPMENT OF THE REPUBLIC OF TYVA
Authors: Balakina G. F.
Published: February 2022

The article discusses the processes of improving the regional policy of Russia from the policy of equalizing the parameters of socio-economic processes of the regions to the policy of stimulating the implementation of competitive advantages of the regions. The territorial heterogeneity of the Republic of Tyva as an object of regulation is investigated. It is determined that the current division of the territory of the republic into four zones: Central, Western, Eastern and Southern, which differ in terms of output and parameters of social development, remains relevant and determines the differentiation of measures for regulating socio-economic processes. It is concluded that in the conditions of improving regional policy in the republic, it is necessary to develop and implement a conceptual document: a concept, strategy or action plan for regulating territorial development, which allows linking goals and resources, which is strategically important due to the border position of the region. In Tyva, it is necessary to form a purposeful policy of regulating territorial development. The purpose of the territorial policy is proposed to be defined as equalizing the access of residents of the republic to social services, the development of border territories to prevent the outflow of population through the adoption of a set of measures, including the activation of natural resource potential.
COMPREHENSIVE DIAGNOSIS OF THE EMPLOYMENT SITUATION IN THE CONTEXT OF HUMAN RESOURCES SECURITY OF THE ENTERPRISE
Authors: Milyaeva L. G.
Published: February 2022

In the context of a crisis economy, the need for an analysis of the employment of enterprise personnel is significantly updated — the most important socio-economic category, which largely determines the level of competitiveness and personnel safety of the economic entity. The theoretical component of the work is devoted to substantiating the essence of the definition of «employment of enterprise personnel», positioned as a system of social and labor relations within the framework of a specific labor cooperation; accordingly, the methodological component of the work is argumentation, description and illustration on conditional examples of seven key points that form the concept of the study of personnel employment at the current research stage. The central place in the article is given to the presentation of the original author’s methodology for a comprehensive (satisfied-structural) assessment of the situation in the field of employment of enterprise personnel, based on the allocation of complex types of employment and the development of the Employment Matrix, which allows you to diagnose the achieved level of personnel security, identify problematic issues and justify targeted management decisions aimed at their normalization. In conclusion, the distinctive features of the methodology are emphasized (simplicity, visibility of the presentation of results, diversification of use, universal nature), and the legality of its replication in specialized publications is justified.
Contact Geometrical Study for Top Emitting 980 nm InGaAs/GaAsP Vertical-Cavity Surface Emitting Lasers
Authors: Chaqmaqchee Faten A.
Published: February 2022

Geometrical contacts of a double mesa structure with 16 rows ×15 columns arrays of top emitting GaAs based 980 nm vertical cavity surface emitting lasers (VCSELs) are fabricated and characterized. In this paper, 5 strained In0.22Ga0.78As/Ga0.9AsP0.1 quantum wells (QWs) within λ/2 thick cavity have been employed. The top and the bottom epitaxially grown mirrors are based on the linear graded Al0.9Ga0.1As/GaAs distributed Bragg reflectors (DBRs) with 20.5 and 37 periods, respectively. Static parameters including threshold currents, rollover currents, maximum optical output power and wall-plug efficiency are extracted from light out power-current-voltage (LIV) of VCSELs with fixed oxide aperture diameter of ∅~ 6 μm and various mesa2 diameters. In addition, spectral emission for 980 nm VCSELs of oxide aperture between ∅~ 6 and 19 μm and with fixed ∅~ 6 μm and different bias currents are analyzed. The highest optical output power of around 33 dBm is observed at bias current of 0.8 mA for short−reach optical interconnect applications.

No Evidence That Exposure to Materialistic Advertisements Influence Appearance Overvaluation and Financial Success Overvaluation in the Self-concept
Authors: Bossom Isabella R. L. , Tabri Nassim
Published: February 2022

Theory and prior research indicate that placing overriding importance on a life domain (e.g., appearance, financial success, health, work, interpersonal relationships) can negatively influence mental and physical health. In particular, people who overvalue appearance have been shown to engage in maladaptive weight-control behaviours and to have eating disorders. Likewise, people who overvalue financial success have been shown to engage in risky gambling and to have disordered gambling. Although the consequences of overvaluing a life domain are palpable, much less is known about its antecedents, which we examined in the current research. According to the Consumer Culture Impact Model, exposure to sociocultural ideals regarding luxury, wealth, and appearance via advertisements influence appearance overvaluation. We proposed that exposure to such sociocultural ideals should also influence financial success overvaluation. We tested the hypothesis that appearance and financial success overvaluation increase in response to viewing materialistic advertisements. First and second year undergraduate students completed self-report measures of appearance and financial success overvaluation in September 2020 (N = 185). They were re-contacted in March 2021 to complete a consumer decision making task. In the task, participants were randomly assigned to a control condition wherein they viewed and compared several non-materialistic advertisements (e.g., pencils, coffee) or to an experimental condition wherein they viewed and compared materialistic advertisements (e.g., champagne, luxury vacation). Afterwards, all participants completed again the same measures of overvaluation. Unexpectedly, linear regression analyses showed that there were no pre-post changes in appearance and financial success overvaluation from before to after exposure to materialistic (relative to non-materialistic) advertisements. Exploratory Bayesian regression analyses revealed support for the null hypothesis. Findings do not support the Consumer Culture Impact Model. Holding materialistic values are discussed as a potential moderator.
Instrument or Appliance? The RCA Theremin, Gender, Labor, and Domesticity
Authors: Latham Clara
Published: February 2022

This article explores the relationship between domestic music making, technological innovation, and labor through a case study of the marketing of the RCA Theremin in 1929. Shortly after the arrival of Russian inventor Leon Theremin in the United States in 1928, plans to develop the Theremin as a commercial musical instrument for the home quickly took shape, aligning it with other commercialized domestic appliances. But the nature of the labor that the Theremin promised, according to its marketers, was different than the labor afforded by the vacuum cleaner or lightbulb: it promised to perform musical work. The domestic sphere was changing with the introduction of appliances to assist housewives in middle-class American homes. This involved changes in audio culture as well. Many forms of musical listening were moving from a public to a domestic sphere via the introduction of the phonograph and radio. The phonograph afforded housewives the convenience of playing Saint-Saëns in their parlors without the labor of practicing the piano, just as the electric light saved them the effort of attending to oil lamps. Marketing materials for the RCA Theremin promoted the instrument as a labor-saving device, aiming to fulfill the role of the piano in middle-class American homes but eradicating the need for practicing. I argue that this promise implicitly reveals the labor of domestic music making, which, like other forms of domestic labor, has been historically rendered invisible within a capitalistic system that values productive over reproductive labor.

Ideology is knowledge or values, which are generically the basis for a person or citizens to know and choose the basic behavior of the understanding that is believed. Pancasila is the basis of the state and the view of life of the Indonesian people, in everyday life both in the community. This ideological attitude is very important to be implanted and implemented, because the Pancasila ideology contains rules that apply as a guide in dealing with and solving various problems. As a form of implementation of Pancasila's ideological attitude in dealing with news in the era of the Covid-19 pandemic, namely being critical in receiving news, seeking data or truth, by filtering first.

Ideologi merupakan pengetahuan atau nilai-nilai, yang secara generik  sebagai landasan bagi seorang atau pula warga dapat mengetahui dan memilih perilaku dasar dari pemahaman yang diyakini. Pancasila merupakan dasar negara dan pandangan hidup bangsa Indonesia, dalam kehidupan sehari-hari baik di lingkungan masyarakat. Sikap ideologi itu sangat penting untuk ditanamkan dan diimplementasikan, karena ideologi pancasila memuat aturan-aturan yang berlakaku sebagai petunjuk dalam menghadapi dan menyelesaikan berbagai permasalahan. Sebagai salah satu bentuk implementasi sikap ideologi pancasila dalam menghadapi berita di era pandemi Covid-19 yaitu bersikap kritis dalam menerima berita, mencari data atau kebenaran, dengan memfilter terlebih dahulu.

Multiple endocrine neoplasia type 1 NM_001370259.2(MEN1):c.466G>C(p.Gly156Arg) is characterized by tumors of various endocrine organs. We report on a rare, growth hormone-releasing hormone (GHRH)-releasing pancreatic tumor in a MEN1 patient with a long-term follow-up after surgery. A 22-year-old male with MEN1 syndrome, primary hyperparathyroidism and an acromegalic habitus was observed to have a pancreatic tumor on abdominal CT scanning, growth hormone (GH) and insulin-like growth factor 1 (IGF1) were elevated and plasma GHRH was exceptionally high. GHRH and GH were measured before the treatment and were followed during the study. During octreotide treatment, IGF1 normalized and the GH curve was near normal. After surgical treatment of primary hyperparathyroidism, a pancreatic tail tumor was enucleated. The tumor cells were positive for GHRH antibody staining. After the operation, acromegaly was cured as judged by laboratory tests. No reactivation of acromegaly has been seen during a 20-year follow-up. In conclusion, an ectopic GHRH-producing, pancreatic endocrine neoplasia may represent a rare manifestation of MEN1 syndrome.

Learning points

Clinical suspicion is in a key position in detecting acromegaly.

Remember genetic disorders with young individuals having primary hyperparathyroidism.

Consider multiple endocrine neoplasia type 1 syndrome when a person has several endocrine neoplasia.

Acromegaly may be of ectopic origin with patients showing no abnormalities in radiological imaging of the pituitary gland.
Effect of combined aluminum-silicon synergistic impregnation and heat treatment on the thermal stability, chemical components, and morphology of wood

Wood is flammable and consumes a lot of energy during processing. To improve this material, wood was pretreated via aluminum sulfate–sodium silicate synergistic impregnation combined with heat treatment. The wood before and after pretreatment was analyzed through the solids weight changes, thermogravimetric and differential thermogravimetric analyses, somke density, scanning electron microscopy, and Fourier-transform infrared spectroscopy. The experimental results showed that the combined treatment could reduce the energy consumption of the heat treatment by catalyzed thermal degradation with aluminum-silicon synergistic impregnation. This procedure improved the thermal stability of the wood. Meanwhile, the combined treatment resolved the problem of increased smoke release caused by the impregnation of aluminum sulfate–sodium silicate modification reagents.

Published: February 2022

Primary care plays an integral role in the management of complex, chronic disease states such as heart failure. However, there is a disconnect between the characteristics of those recruited into clinical trials and those managed in the real world, which means the contribution and consideration of primary care in current guidelines is suboptimal. In this article, the authors explore key issues in the diagnosis and management of heart failure that need to be addressed from a primary care perspective. This article focuses on the issue of heart failure with preserved ejection fraction and the integration of new clinical epidemiology and trial evidence into clinical practice. In response, the authors advocate for dedicated guidelines for the primary care management of heart failure, the development of strategies to facilitate communications between health professionals in acute and community care and a renewed focus on researching optimal models of heart failure care in the community.

Lemon merupakan salah satu buah herbal yang sering digunakan untuk kesehatan manusia. Uji coba ini bertujuan untuk mengetahui respons juvenil ikan kakap putih (Lates calcarifer) terhadap pemberian pakan pelet komersial yang ditambahkan dengan ekstrak buah lemon (Citrus limon). Uji coba menggunakan ikan kakap putih dengan ukuran 10 cm. Masing-masing 50 ekor ikan sehat ditempatkan dalam tiga bak fiber volume 500 L. Setiap kelompok ikan dalam satu bak diberi pakan pelet komersial dengan penambahan A. 100 g ekstrak isi buah lemon/kg pakan, B. 100 g ekstrak isi dan kulit buah lemon/kg pakan, dan C. 100 mL air tawar steril/kg pakan sebagai kontrol. Pakan diberikan dua kali sehari sampai kenyang selama enam minggu pemeliharaan. Pengamatan dilakukan terhadap respons ikan terhadap pakan, pertambahan panjang dan bobot, serta sintasan ikan. Hasil uji coba menunjukkan bahwa ikan kakap putih memiliki respons yang baik terhadap pakan yang diberi penambahan ekstrak buah lemon (A dan B). Hal tersebut ditunjukkan dengan peningkatan panjang dan bobot tubuh ikan kakap putih pada perlakuan A (3,4±0,7 cm dan 17,2±6,7 g) yang sedikit lebih tinggi dibandingkan dengan kontrol C (2,2±0,2 cm dan 16,7±9,2 g) dan perlakuan B (2,3±0,6 cm dan 13,3±6,5 g). Pemberian ekstrak isi dan kulit buah lemon tidak mempengaruhi sintasan ikan (sintasan semua perlakuan 100%). Hasil tersebut menunjukkan bahwa penambahan ekstrak isi buah lemon bermanfaat dalam meningkatkan pertumbuhan ikan kakap putih.
