Radiative impacts of Californian marine low clouds on North Pacific climate
Authors: Miyamoto Ayumu , Nakamura Hisashi , Xie Shang-Ping , Miyasaka Takafumi , Kosaka Yu
Published: March 2023

The northeastern Pacific climate system is featured by an extensive
low-cloud deck off California on the southeastern flank of the
subtropical high that accompanies intense northeasterly trades and
relatively low sea surface temperatures (SSTs). This study investigates
climatic impacts of the low-cloud deck by turning low-cloud radiative
forcing on and off only within the subtropical northeastern Pacific in a
coupled atmosphere-ocean model. The low-cloud radiative forcing causes a
local SST decrease of up to 3ºC on an annual average, with the response
extending southwestward through the wind-evaporation-SST (WES) feedback.
The SST decrease peaks in summer under the seasonally enhanced
insolation and the seasonally shallow ocean mixed layer. The lowered SST
suppresses deep-convective precipitation that would otherwise occur in
the absence of the low-cloud deck. The resultant anomalous diabatic
cooling induces a surface anticyclonic response in summer and autumn as
a baroclinic Matsuno-Gill pattern. On its equatorward flank, the
enhanced trade winds further cool SST as the WES feedback, leading to
the southwest propagation of the coupled response. The enhanced trades
accompany the intensified upper-tropospheric westerlies, strengthening
the vertical wind shear that, together with the lowered SST, acts to
shield Hawaii from powerful hurricanes. On the basin scale, the
anticyclonic surface wind response accelerates the North Pacific
subtropical ocean gyre to speed up the Kuroshio by as much as 30%. SST
thereby increases along the Kuroshio and its extension, intensifying
upward turbulent heat fluxes from the ocean to increase precipitation.
Examination of steel compatibility with additive manufacturing and repair via laser directed energy deposition

Published: March 2023

High strength steels are a vital material for aerospace applications but are also prone to damage from fatigue, corrosion, and wear. Additive manufacturing (AM) processes such as laser directed energy deposition (L-DED) offer a means for repairing both the geometry and structure of damaged steels; however, significant variation in tensile properties have been reported following repair. While previous studies have tried to improve performance through postdeposition heat treatment, such practices may not be possible for commercial parts due to risks of distortion and thermal damage to the substrate. Instead, this investigation analyses the role of the intrinsic heat treatment effect on as-deposited tensile properties through a detailed review of both AM and AM repair literature. By assessing a wide variety of high strength steels, the links between conventional heat treatment parameters and steel performance in AM are established, and the role of steel composition understood. This review is supported by additional AM and L-DED repaired samples, with consistent parameters used between steels to ensure similar thermal histories, and eliminate potential discrepancies seen between AM machines. The results demonstrate the effect of intrinsic heat treatment on martensitic and precipitation hardening steels, the role of residual heat and heat extraction through the substrate, and flag potential issues faced by steels at risk of temper embrittlement. Taken together, these findings provide a clear vision for the advancement of AM repair and the optimization of mechanical performance.

Published: March 2023

The packaging that is widely used is plastic packaging, but this material has a weakness that is difficult to decompose and isn’t biodegradable, therefore edible film can be an alternative primary packaging for food products. The material used consists of gelatine made from duck feet with the addition of various concentrations of glycerol.  Duck feet is an underutilized portion of the animal's anatomy, yet they contain collagen, which has the potential to be the raw material for gelatine and edible films. The study was undertaken utilizing duck feet as a source of raw material, which was subsequently processed into gelatine for use in the production of edible films using different glycerol treatments. The treatments comprised of glycerol concentrations of P1 = 10%, P2 = 20%, P3 = 30%, P4 = 40%, P5 = 50%, and P6 = 60%. The findings indicated that the application of glycerol significantly affected the films' solubility, water absorption, and tensile strength (P<0.05), but didn’t significantly affect the elongation of edible films. (P>0.05). The optimal concentration of glycerol for edible film in this study was obtained by using 20% glycerol, with a physical characteristic value of 40.25% solubility, 24.23% water absorption, tensile strength is 0.57 MPa, and elongation is 90%.

Konsep Wasatiyah Dalam Hukum Islam Perspektif Hasbi Ash-Shiddeqy
Authors: Ongku Hsb Mara
Published: March 2023

Wasatiyah memiliki makna yang sepadan dengan tawassuth berarti tengah, i’tidal berarti adil tawazun berarti berimbang di dalam Al-Qur’an sendiri terdapat kalimat ummatan wasathan  yang menjadi konsep muslim sebagai umat pertengahan, tidak berat sebelah atau tidak ekstrim ke kanan dan ke kiri tetapi berada di tengah begitu juga dalam hukum Islam wataknya bersifat wasatiyah yang berarti dalam menerapkan hukum harus bersikap adil, dan seimbang. Pembahasan wasatiyah Islam sebenarnya bukanlah hal yang baru bagi bangsa Indonesia tetapi ini merupakan warisan dari para pendahulu bangsa sudah meletakaan dasar-dasar beragama yang toleran, inklusif, karena sejatinya ajaran Islam itu sendiri sangat moderat. Metode  penelitian yang digunakan adalah deskriptif-analitis dengan jenis library research (penelitian pustaka). Hasil penelitian ini menyebutkan bahwa menurut Hasbi Ash-Shiddieqy hukum Islam menempuh jalan tengah, jalan yang imbang tidak terlalu berat ke kanan mementingkan kejiwaan tidak berat ke kiri seperti antara suami dan istri seorang suami tidak boleh  berat sebelah seperti membuat istrinya terkatung-katung (terlantar) ditalak tidak, dipergaulipun tidak, kemudian tidak boleh hanya memihak kepada salah seorang istri apabila istrinya lebih dari satu sehingga menyebabkan timbulnya kekecewaan pada istri yang lain. Hakikat konsep wasatiyah dalam hukum Islam memberikan keselarasan dan keseimbangan hukum Islam selalu berdasarkan kepantasan dan kecukupan seperti hukum kafarat yang membatalkan sumpah,  kafaratnya sesuai kebiasaan dengan memberi makan sepuluh orang miskin dan makanan yang pantas dan secukupnya.

A Latent Profile Analysis of Academic Coping Strategies: Associations with Self-determination, (dis)Engagement, and Well-being
Authors:   Korea Univ. Institute of Educational Research, Moon Jooyeon , Lee Eunju
Published: March 2023

This study was conducted to examine how adaptive and maladaptive academic coping strategies are combined and how different combinations are associated with predictors and outcomes, respectively. A latent profile analysis was applied to the data of 611 adolescents, with five types of regulation on the self-determination continuum as predictors and (dis)engagement and well-being as outcomes. The results were as follows. First, five distinct profiles of coping strategies were identified: low, adaptive, high-adaptive, average, and high-maladaptive profiles. Second, the more students were autonomously motivated, the more they were likely to belong to the adaptive, high-adaptive profiles. In contrast, the lower quality motivation they reported, the less they were likely to belong to the two profiles characterized by high level of adaptive coping strategies. Finally, there were significant differences in (dis)engagement and well-being between the five profiles. The high-adaptive, adaptive, high-maladaptive, average and low profiles were shown to be high on engagement in a descending order. Both low and high-maladaptive profiles displayed the highest disengagement, whereas both adaptive and high-adaptive profiles displayed the lowest disengagement. The adaptive and high-adaptive profiles were higher in well-being than the other three profiles. These findings provide a full understanding of coping strategies adolescents use in the face of academic difficulties and suggest practical implications on targeted interventions to facilitate their reliance on adaptive coping strategies.

This research aims to determine the effectiveness of the Project-based 6E (engagement, exploration, explanation, elaboration, extension and evaluation) Learning Model. The researchers created the model by combining the basic features of project-based learning with an understanding of the learning cycle. The pre-test/post-test semi-experimental design, in which no control group is included, was used in the study. The study group in the research consisted of junior students studying at the Turkish Teaching and English Language Teaching departments of the Faculty of Education, Düzce University, in the fall semester of the academic year 2020–2021. The experimental process was structured according to the Project-based 6E Learning Model. Two different types of data, namely, qualitative and quantitative, were collected to determine the effectiveness of the experimental process. It was concluded that the students found the model efficient, effective and attractive. The model positively changed students’ perceptions of values and values education. It was also seen that the model enables students to realise their values, review and question the values, reinforce them, complete their deficiencies and gain new values. Due to the effect of the learning model, students positively experienced significant changes in their teaching perception.
Challenges in virtual team communication in the context of virtual exchange experience
Authors: Ala-Kortesmaa Sanna , Muñoz Candice
Published: March 2023

As technology has enabled people across the world to collaborate and create virtual communities, the ability to interact in computer-mediated, cross-cultural environments in a meaningful way has become a necessity. This is particularly true for younger adults who operate in virtual teams during their studies, for instance in virtual exchange projects, and later in their professional life. In this qualitative study, we examined the features and functionality of cross-cultural communication in virtual exchange teams. By analysing three datasets produced by Finnish university and American community college students (n=38) who participated in a virtual exchange, we examined what kinds of challenges emerge in the communication of virtual teams and how students use theories of computer-mediated communication when trying to make sense of those challenges. The results of the reflexive thematic analysis indicated that the challenges in communication of virtual teams stem from cultural and motivational differences. These challenges could be alleviated by increasing the shared work time allocated for social information sharing and for constructing appropriate, team-specific ways to express online social presence and propinquity. The findings highlight the meaningfulness and relationality of virtual team communication and provide insight into motivational factors and the sense of belonging when communication challenges arise.

Published: March 2023

This research aimed to evaluate the potential effects of microbial fertilizer on the growth, yield and quality parameters and fertiliser savings of lettuce and cucumber. The study had control (C), microbial fertilisation (MF), chemical fertilisation (CF), chemical fertilisation + microbial fertilisation (CF + MF), 50% chemical fertilisation + microbial fertilisation (50% CF + MF) and dipping into microbial fertiliser + chemical fertilisation (D + CF) treatments. The highest head length, root collar diameter, soluble solids and leaf number of lettuce were obtained in D+CF. Maximum chlorophyll contents were obtained in CF, CF + MF and D + CF, all of which were higher than the C application. D + CF and CF + MF resulted in the highest total and marketable yields. In cucumber cultivation, although the highest fruit length was obtained in CF, CF + MF, 50% CF + MF and D + CF were only slightly less than CF. The highest fruit diameters were in CF + MF and 50% CF + MF. The chlorophyll contents were significantly more in 50% CF + MF and D + CF than in other applications. The highest first- and second-class yields were in 50% CF + MF and were significantly higher than those in C and CF. Average fruit weight was also higher in all MF applications. It counclud that the alone MF application is not important, so MF has to be used with organic or chemical fertilisers in lettuce and cucumber cultivation.

Published: March 2023

The split sheet used at a recording studio is one of the essential means for any creative artist who understands its implementation benefits from the royalties that the creative work generates as it gets commercial merchandise. However, surprisingly, Ghanaian music producers and practitioners are yet to tap into the full potential of this avenue. This paper investigates the awareness and benefits of the split sheet among Ghanaian music producers and practitioners in the recording industry and the extent to which they have explored it. Using a mixed-methods mode of inquiry for data collection, we sampled music producers and practitioners (n = 218) in Ghana to briefly analyse the moneymaking through split sheets of songs available to music practitioners in Ghana’s recording industry. It was noted that 94.9% of respondents were unaware of the split sheet, while 92.7% did not know the benefit of the split sheet. However, only 4.6% of the respondents had used the split sheet. Subsequently, we conclude that the low awareness of the split sheet among Ghanaian music producers and practitioners compromises the decorum of the business side of creativity in the Ghanaian recording industry. Therefore, we recommend that more intensive education be undertaken to sensitise Ghanaian music producers and practitioners to the benefit of the split sheet in their daily work to enhance revenue generation.

Published: March 2023

Purpose: Given the importance of monitoring and managing land cover, especially in countries with continental proportions, such as Brazil. This research aimed to compare two remote sensing image classifier algorithms.
 
Method/design/approach: The article compared the Gaussian Mixture Model and Random Forest classification algorithms, using Landsat 8 image, which was classified in a supervised way, in the Dezetsaka plugin of QGIS. The analysis of the performance of each model was performed using the Kappa index and Total Accuracy.
 
Results and conclusion: The results showed that the Random Forest algorithm was more efficient than the Gaussian Mixture Model. Taking the Kappa Index (K) and Total Accuracy (po), the models obtained the following performances in the classification of classes: the Random Forest Model (K= 0.94 and po= 96.31) and the Gaussian Mixture Model obtained (K=0.85 and po=90.60).
 
Research implications: The results can support the choice of classification method by researchers and others interested in monitoring land cover.
 
Originality/value: This is a unique proposal, which compares an algorithm based on Machine Learning with another one from the category of probabilistic models. Interesting, since machine learning techniques have been gaining notoriety in several contexts.
Diagnosis of the Sustainability of a Poultry Value Chain From the Perspective of Environmental Management Accounting
Authors: Rodrigues Valquíria Duarte Vieira , Wander Alcido Elenor , Da Rosa Fabricia Silva
Published: March 2023

Purpose: This paper aims to present the diagnosis of the sustainability of a poultry value chain from the perspective of Environmental Management Accounting.
 
Theoretical framework: The main theoretical basis for the development of the research was the perspective of the Environmental Management Accounting (EMA) system that contributes to the generation of value. This chain will be studied under EMA and thus overcome the barrier for the implementation of an EMA system. When the organization succeeds in implementing it and making it an integral part of the environmental strategy, the EMA provides an efficient approach to environmental, managerial and financial information.
 
Method/design/approach: The methodology used was the case study, the investigation, of an exploratory and quali-quantitative nature. Descriptive and quantitative information about environmental heritage was analysed, such as forest diagnosis, waste generation, water resources, energy and emissions, environmental management and accounting in the various links of the poultry production chain in the state of Goiás.
 
Results and conclusion: The results demonstrate the vertical business strategy and the adoption of a circular business model by the poultry chain. It was possible to confirm that Environmental Management Accounting (EMA) makes it possible to map processes, identify physical and financial aspects, establish ecological control mechanisms, and highlight actions, policies and sustainability programs at the production chain level. It is concluded that to diagnose information of a descriptive and quantitative nature, from the EMA perspective, the level of planning of the integrating company and integrated farms must be considered, which directly impacts the monitoring and continuous evaluation of processes. When applied, the EMA contributes to the knowledge of the performance of the chain.
 
Research implications: The contribution of this study is based on two pillars: i) the methodology applied with data collection from primary sources; and, ii) access to data, which allowed results, until then, not observed in the literature.
 
Originality/value: The contribution of the study lies in the fact that it is a study applied to the production chain, with access to primary and unpublished data, which advances the development and applicability of science in the area and/or practices of socio-environmental management of organizations.

Published: March 2023

Purpose: This study aims to analyze the relationship between consumer engagement with the Beta brand and the purchase intention of ecological products sold by the company.
 
Theoretical framework: It builds on the literature on consumer engagement and behavior and green or ecological products
 
Method/design/approach: In this study, the research was characterized as quantitative, descriptive and explanatory, with data collected through a survey. The study population was made up of consumers and potential consumers of Beta Cosmetics, a company that operates in the beauty market, offering sustainable solid products. A sample composed of consumers who agreed to participate in the survey was used, totaling 107 respondents.
 
Results and conclusion: The results indicate that conscious participation positively affects the purchase intention of these products, and that consumers who regularly buy the products are more engaged, enthusiastic and conscious, and perceive greater value in the products. Meanwhile, consumers who rarely buy the products have high purchase intention, but are more sensitive to the price, as these products are more expensive than traditional products on the market.
 
Research Implications: This study has an impact on practical implications in the practice of ecological products, as it emphasizes that engagement and awareness may not lead to sales. Although consumers perceive value in ecological products, the high price plays an important role in preventing the realization of purchase intentions.
 
Originality/value: The paper provides evidence of the determinants of ecological products purchase intentions. It also shows that developing ideas that will educate, attract and engage consumers might strengthen their purchase intention, specially if combined with a competitive price.

Published: March 2023

Background: Preimplantation genetic testing (PGT) is used to identify a pathogenic variant in embryos created through in vitro fertilization. A "variant of uncertain significance" (VOUS) is a genetic variant discovered through genetic testing but with unknown clinical significance. The primary goal is to gauge geneticists' perspectives on performing PGT-M for VOUS in Saudi Arabia, which results in the development of recommendations from higher authorities regarding the criteria of PGT-M in clinical practice.
Methods: After reviewing the literature, a cross-sectional study was conducted employing questionnaire developed using survey monkey. The reliability of the questionnaire was assessed in terms of internal consistency and Cronbach's alpha-assessed test-retest.
Results: In particular, a total of 96 Saudis and non-Saudis, male and female geneticists, agreed to participate in the study. Out of the 96 geneticists, 56 (59.6%) were female. Most participants were of Saudi origin, with a percentage of (76.6%). The most important finding of this study is that 64% of geneticists opposed performing PGT-M for VOUS. The outcome that 94.5% of geneticists concurred that PGT-M is poorly understood was another noteworthy finding.
Conclusion: Future research with a larger sample size is required for performing PGT-M for VOUS, which will help in developing guidelines for PGT-M in Saudi Arabia.
