Identidad y gestión del cambio en la industria de la moda
Authors: García Barriga María 
Published: June 2023

Las teorías existentes sobre las dinámicas de la moda giran en torno a la decadencia y la desaparición de unos productos y al nacimiento de otros nuevos (Rogers, 1962), pero ¿esto sucede de verdad?, ¿los productos de moda y su mensaje desaparecen por completo cuando se cumple su ciclo de vida? o ¿encajan estos modelos dentro de la realidad actual orientada a la economía circular y al progreso de la inteligencia artificial? La moda no sólo puede entenderse como un mensaje visual (Barthes,1983) en forma color y textura que comunica la identidad, verdadera o falsa, de quien la porta; sino que, como campo interdisciplinar y poliédrico que es (Kaiser, 2012) puede filtrarse desde una perspectiva de negocio como un “río que nunca deja de ﬂuir” (Stone, 2008) a la orilla de un ecosistema de mercado cuyas marcas desarrollan identidades individuales (Aaker, 1997) que representan a una identidad colectiva o social (Simmel, 1971) para construir y mantener su valor a través de un objeto visual en la mente del consumidor. A diferencia de otras disciplinas, la identidad de las marcas de moda se compone de un sistema de atributos en constante transformación (Collins y Porras, 1994) y, por eso, el cambio coherente y consistente en los atributos de identificación y diferenciación (Saviolo, 2000) de una marca ha de gestionarse en movimiento, no a través de un sistema estático anclado a un tiempo y a un espacio concretos (Kapferer, 2008), basado en la obsolescencia programada de las prendas de ropa (Rogers, 1962), como el que hemos conocido hasta ahora. Esta reﬂexión teórica tiene como objetivo profundizar en el modo en el que estamos enfocando el ciclo de vida del producto en las firmas de moda y es una “llamada a la acción”, tal y como proponen los doctores Wanik y Bazaki, (2023) sobre la necesidad de nuevos modelos de difusión de las innovaciones y desarrollo de producto en la industria de la moda.

Published: June 2023

This research aims to study the adaptation of a flexible working system and what supports team productivity in pandemic-changing situations. It uses qualitative research by performing in-depth interviews and focuses on the interviews of eight managers of four supporting functions: IT, Finance, HR, and Legal, in three leading companies in Indonesia The finding in this research shows the companies have experienced and still adapting to formulate a new working system. To support team productivity in the new working system, several factors need to be addressed, such as: facilities and technical support, the adaptation of SOP and job function, supervisor control, company and team agility, improved communication, work environment, and self-motivation. The new working system is expected to bring impact: improve productivity, cost reduction, environmental improvement, and employee well being. Further quantitative research is recommended to validate the factors supporting a flexible working system that influence team productivity and the expected impact. This study is expected to help management or organization to a better understanding of factors supporting the adaptation of the flexible working system needed to maintain team productivity in this changing situation. To the best of our knowledge, this research is the first to study the adaptation of a flexible working system and what factors are needed to support team productivity in pandemic-changing situations.
Trend and homogeneity test analysis for rainfall over a 121-year time period in the desert district of Western Rajasthan, India
Authors: Singh Hajari , Choudhary M. P. 
Published: June 2023

Abstract

The Thar Desert receives very scarce and scanty rainfall; hence, water is given the top priority and importance in daily life. During the past decades, there has been a variation in the trend of the rainfall, climate, and other atmospheric conditions in the Jaisalmer district. An analytical study has been carried out to investigate this changing environmental phenomenon. Sixteen grids have been selected to study the trend and magnitude of the slope for rainfall using the MMK (Modified Mann–Kendall) test and Sen's Slope estimator. Pettitt's test, SNHT (Standard Normal Homogeneity Test), and Buishand's test have been used to find trend change year in 121-year time series of rainfall. Mean annual rainfall for all grids shows positive values of Kendall's tau and Sen's Slope, which indicate that trend interpretation is rising, and test interpretation is increasing. Most of the results obtained from grids show the year ‘1992’ as the trend-changing year. A significant rise in mean annual rainfall has been noticed after the change of year in the study area. This type of study has not been conducted earlier in the region to identify the rainfall trend and change of year of trend. This study will help policymakers to take necessary action.

Published: June 2023

Abstract

In the ballasted flocculation, high-speed sedimentation of suspensions is achieved using a microsand as a ballast material and a polymer flocculant combined with microflocs made of polyaluminum chloride (PAC) as an inorganic coagulant. In this study, three turbid water samples containing kaolin clay (kaolin concentration: 20, 200, and 500 mg/L) were treated by coagulation–sedimentation and ballasted flocculation. The effects of pH and PAC dosage, which are the controlling parameters for coagulation, and the microsand (silica sand) and polymer dosages, which are the controlling parameters for ballasted treatment, on the treatment efficiency and floc settling velocity were examined. The floc settling velocity under the optimum conditions was 17 times higher than that of the conventional coagulation–sedimentation process using PAC. The turbidity was 0.54 turbidity unit (TU) (TU as the kaolin standard), and its removal efficiency was 99.7%. Furthermore, turbid water samples with different kaolin concentrations (20 and 500 mg/L) were treated via the ballasted flocculation. In this study, fundamental information on the optimization of each dosage condition of coagulant, ballast, and polymer and pH condition in ballasted flocculation was obtained, and the removal mechanisms under optimal, underoptimistic and overoptimistic conditions were proposed.

Published: June 2023

Abstract

Cyanotoxins produced by cyanobacteria are a significant threat to human health. However, their responses to nitrogen (N) supplies could differ between N-fixing and non-N-fixing species, which has been poorly understood. This study aimed to compare the responses of the non-N-fixing Microcystis aeruginosa and N-fixing Nostoc sp. to varying concentrations of nitrate and ammonium. This comparison had been conducted by analyzing chlorophyll-a contents, maximum quantum efficiencies of photosystem II, microcystin production, and related gene expressions. Our findings revealed that nitrate substantially stimulated the growth of both M. aeruginosa and Nostoc sp. with biomass increase by 366.2 ± 56.5 and 93.0 ± 14.0%, respectively, at 16 mg-N/L. In contrast, high ammonium concentrations suppressed their growth. Furthermore, the intracellular concentration of microcystins produced by M. aeruginosa was higher under high nitrate. Extracellular microcystins showed an opposite trend to increases in nitrate and ammonium. Ammonium increases the production and releases microcystin from Nostoc sp. N metabolism genes showed a similar trend with toxin formation genes, which were up-regulated under the high N treatments. This study provides valuable insights into the impacts of N supplies on growths of N- and non-N-fixing cyanobacteria, as well as microcystin production, which helps to develop effective strategies for managing cyanobacterial blooms.

Published: June 2023

The science and methodology of living a physically, physiologically, spiritually, and mentally balanced life is what we call as Ayurveda. It does not merely focus on curing the diseases of the unhealthy people but it also prioritises preservation of good health in already healthy individuals. The lifestyle we have moulded ourselves into after the modern civilization took place has kept us at a bay from having a perfect health, a healthy mind, and a healthy body. When it comes to maintaining good health or even curing the diseases of the patients, first thing we should take care of is the diet. i.e. ‘Ahara’ as we call it in Ayurvedic terminologies. Ayurveda has also coined the term ‘Trayopasthamba’ which literally means the three pillars of human health. It includes- Ahara, Nidra & Bramhacharya.[1] Ahara is the utmost important factor when it comes to leading a disease free, healthy life as per Ayurveda. Today, even modern science cannot deny the impact of diet on human health. A German Philosopher Ludwig Feuerbach coined a famous phrase ‘we are what we eat’ which Ayurveda approves of and supports with many theories. This article focuses on Acharya Sushruta’s perspective of ‘Hita-Ahita Ahara’ along with Pathyatam Ahara and how it directly impacts human health.
Diagnostic Test Accuracy of Deep Learning Prediction Models on COVID-19 Severity: Systematic Review and Meta-Analysis
Authors: Wang Changyu , Liu Siru , Tang Yu , Yang Hao , Liu Jialin 
Published: June 2023

Background
Deep learning (DL) prediction models hold great promise in the triage of COVID-19.

Objective
We aimed to evaluate the diagnostic test accuracy of DL prediction models for assessing and predicting the severity of COVID-19.

Methods
We searched PubMed, Scopus, LitCovid, Embase, Ovid, and the Cochrane Library for studies published from December 1, 2019, to April 30, 2022. Studies that used DL prediction models to assess or predict COVID-19 severity were included, while those without diagnostic test accuracy analysis or severity dichotomies were excluded. QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2), PROBAST (Prediction Model Risk of Bias Assessment Tool), and funnel plots were used to estimate the bias and applicability.

Results
A total of 12 retrospective studies involving 2006 patients reported the cross-sectionally assessed value of DL on COVID-19 severity. The pooled sensitivity and area under the curve were 0.92 (95% CI 0.89-0.94; I2=0.00%) and 0.95 (95% CI 0.92-0.96), respectively. A total of 13 retrospective studies involving 3951 patients reported the longitudinal predictive value of DL for disease severity. The pooled sensitivity and area under the curve were 0.76 (95% CI 0.74-0.79; I2=0.00%) and 0.80 (95% CI 0.76-0.83), respectively.

Conclusions
DL prediction models can help clinicians identify potentially severe cases for early triage. However, high-quality research is lacking.

Fatigue crack growth modelling considering a damage regularization approach
Authors: Sérgio E.R. , Antunes Fernando , Neto Diogo 
Published: June 2023

An integral regularization method was applied to the
Gurson-Tvergaard-Needleman (GTN) damage model to address the plastic
deformation localization at the crack tip. The parameters for the
constitutive model were calibrated with an evolutionary algorithm. The
model was applied to predict ductile fracture of a tensile specimen,
allowing mesh convergence and geometry independence. Fatigue crack
growth was predicted through a node release strategy, obtaining a very
good approximation to the experimental results in the upper part of the
Paris Regime. Mesh independence was verified for medium/high Δ K
levels, but near the threshold regime no mesh independence was obtained
and da/dN was overestimated. The characteristic length for the
non-local model was defined as the reverse plastic zone size, which
indicates that this should be the fatigue process zone. Finally, at the
accelerated regime, final fracture loci predictions agree with the
experimental results, but mesh independence was barely achieved.

Authors: Safitri Ranni Merli 
Published: June 2023

The facts of pre-marital sexual behaviour (PSB) in adolescent are worrying, then if this condition continued so Indonesia would have low quality generation both physically and psychologically. This research addressed to validate pre-marital sexual behaviour scalogram. Validation process is essential because the useful measurement tool will be able to reveal pre-marital sexual behaviour in order to acquire a precise and accurate description of adolescents pre-marital sexual behaviour. Four hundred junior high school students participated in this study. Rasch analysis was applied to validate the scalogram that consisted of 10 items ranging from the most until the least PSB committed by participants, using the R program latent trait modelpackage. The results showed that this scalogram is sensitive to describe PSB in both low level (θ < 0) and high level (θ >2,5).
Achievement goal viewed from parental involvement
Authors: Muttaqin Fuzta Fauzal , Soetjipto Helly Prajitno 
Published: June 2023

Parent involvement is a concept which includes children’s education. Research and theories suggest that parent involvement can predict children’s achievement goal. The aims of this research is to know whether parent involvement can predict the children’s achievement goal. Yogyakarta high-school students (185 males and 379 females) were selected to fill in two questionnaires which assessed both their perceptions of parent involvement and the students’ achievement goals. SEM analyses showed that the model was fit to explain the correlation between parent involvement and achievement goal. Results of this study revealed that parent involvement is a predictor of students’ achievement goals. Parent involvement had an indirect effect on mastery goals and performance goals also in approach and avoidance. Parent involvements’ effect on performance is higher than the effect on mastery. Parent involvements’ effect on approach is higher than the effect on avoidance. Implications of these findings for students’ achievement goal and academic achievement are discussed.
Влияние использования конгруэнтного подхода к визуализации на изучение курса CS2

Published: June 2023

The majority of computer science (CS) educationists agree that learning the Data Structures course (CS2) is very difficult among novices due to its complexity. Consequently, learning the Data Structures course has been associated with a high failure rate. To enable learners understand data structures, algorithms visualizations (AVs) were proposed. Despite the long-term use of AVs in teaching and learning data structures, research shows that such tools have not been as pedagogically effective as expected. This study aimed to evaluate the effectiveness of using a congruent visualization (CV) framework on learning data structures. The framework employs a combination of two congruent program visualization tools, which involve machine-driven and learner-driven approaches. The effectiveness of using the CV framework was evaluated using a combination of experiment, grade analysis, and questionnaire methods. The subjects of the study were 887 first-year undergraduate students from the College of Informatics and Virtual Education (CIVE) of the University of Dodoma in Tanzania, studying the CS 122 Data Structures course. Results show that the use of the CV framework improved both students’ test performance and examination pass rates compared to the traditional approach. Students’ responses from a follow-up survey showed that the use of the CV framework increased students’ motivation and confidence in learning the Data Structures course.
Большинство преподавателей информатики (И) согласны с тем, что изучение курса структур данных и алгоритмов (CS2) является сложным процессом из-за его высокой когнитивной нагрузки. Следовательно, изучение CS2 было связано с высоким уровнем неуспеваемости. Чтобы помочь снизить высокую когнитивную нагрузку, возлагаемую на учащихся изучающих CS2, были предложены алгоритмы визуализации (АВ). Несмотря на длительное использование АВ в преподавании и изучении CS2, исследования показывают, что такие инструменты не были столь педагогически эффективными, как это ожидалось. Это исследование было направлено на изучение влияния использования подхода конгруэнтной визуализации (КВ) в преподавании и изучении CS2. В этом подходе используется комбинация двух совместимых инструментов визуализации программ, которые включают подходы, управляемые машиной, и подходы, управляемые учащимся. Воздействие использования КВ-подхода оценивалось с использованием комбинации экспериментов, анализа документов и методов анкетирования. Объектами исследования стали 887 студентов первого курса бакалавриата Колледжа информатики и виртуального образования (CIVE) Университета Додомы в Танзании, изучающих CS2. Результаты показывают, что использование подхода КВ улучшило как показатели непрерывной оценки учащихся, так и показатели результатов сдачи выпускных экзаменов по сравнению с традиционным подходом. Ответы учащихся на последующий опрос показали, что использование подхода CV повысило мотивацию и уверенность учащихся в обучении CS2.
