Abstract. Human actions induce and modify droughts. Yet, there remain scientific gaps regarding how anthropogenic dynamics and hydrological processes are intrinsically entangled in drought evolution. This poses the challenge of developing ways to evaluate human behavior and its pattern of co-evolution with the hydrological cycle, mainly related to water use and landscape modifications. We propose that prospect theory explains the emergence of drought impacts, such as crop losses and water shortage, if they are considered as failed welfare expectations (“prospects”) due to water shortage. This behavioral economic theory is dominantly applied to explain decision-making processes under uncertainty. We argue that it can also contribute to explaining socio-hydrological phenomena such as reservoir effects. This new approach can contribute to bridging natural and social sciences perspectives for more integrated drought management that takes into account the local context

Published: June 2023

Abstract. This study provides the first inter-comparison of different state-of-the-art approaches and frameworks that share a commonality in their utilization of satellite remote sensing data to quantify irrigation at a regional scale. The compared approaches vary in their reliance on either soil moisture or evapotranspiration data, or their joint utilization of both. The two compared frameworks either combine satellite and rainfed hydrological models in a baseline framework or use soil water balance modeling in a soil moisture-based inversion framework. The inter-comparison is conducted over the lower Ebro catchment in Spain where observed irrigation amounts are available for benchmarking. Our results showed that within the baseline framework, the joint approach using both soil moisture and ET remote sensing data, only differed by +17 mm from the irrigation benchmark (922 mm) during the main irrigation season over two years, and by +41 mm and -228 mm for approaches relying solely on soil moisture and ET, respectively. A comparison of the different frameworks showed that the main advantage of the more complex baseline framework was the consistency between soil moisture and ET components within the hydrological model, which made it unlikely that either one ended up representing all irrigation water use. However, the simplicity of the soil moisture-based inversion framework, coupled with its direct conversion of soil moisture changes into actual water volumes, effectively addresses the key challenges inherent in the baseline framework, which are associated with uncertainties related to an unknown remote sensing observation depth and the static depth of the soil layers in a conceptual model. The performance of the baseline framework came closest to the irrigation benchmark and was able to account for the precipitation input, which resulted in more plausible temporal distributions of irrigation than what was expected from the benchmark observations.
Child as method: A device to read the geopolitics of childhood
Authors: Burman Erica
Published: June 2023

Child as method is an analytical approach addressing socio-political practices focusing on the positioning accorded the child/children that highlights the necessary intersections between political economies of childhood with geopolitical dynamics, while countering normalized and hegemonic functions (of abstraction and individualization) typically enacted by figurations of the child/childhood. It is presented as a creative transformation of Chen’s (2010) Asia as method, engaging Mezzadra and Neilson’s (2013) Border as method as well as feminist, specifically intersectionality, theory. The status of ‘method’ in child as method, is considered, alongside its potential contribution to childhood studies and social theory as a psychosocial counter to dominant technologies attending childhood.

Published: June 2023

The use of Information and Communication Technology (ICT) is the primary goal of the construction of a smart city, with the end goal being a more efficient management of urban resources such as electricity, public transportation, roadways, and wastewater management systems along with judicious use of resources and infrastructure. It is necessary for the technologies to make a contribution to the building of an inclusive society that has a high level of civic involvement and transparency. Therefore, it is vital to investigate the behavior of people, their motivation, incentives and the elements that impact the desire to use and the use of the communication technologies for the purpose of resolving day-to-day responsibilities and problems. We used the UTAUT model in addition to the structural equation modelling based on partial least squares (PLS-SEM). In the UTAUT model, these major contributors are Behavioral Intention and Use Behavior. The findings of this research will enable the authorities of Saudi Arabia to facilitate all of the processes of putting the smart city concept into action by increasing the population's involvement in the use of applications along with cybersecurity framework in all as-pects of day-to-day life.

Published: June 2023

The production of confectionery products is one of the most in-demand industries. Due to this, various assortments of confectionery products and production technologies have expanded. Following modern requirements, the product's appearance, taste, aroma, and nutritional value should be appropriate. Accordingly, to create a new range of gingerbread products, chickpea and bean flour, and sugar beet powder as a sugar substitute were introduced into the recipe: 10%, 15%, and 20% of the wheat flour in the original recipe were replaced by chickpea flour and bean flour; also, 30 and 60 g of the 125 g of sugar in the recipe was replaced by beet powder. A fully factorial experimental design was created to perform the work. According to this plan, control and 8 research samples of gingerbread were cooked and prepared. Organoleptic and physicochemical analysis of these finished products was performed. Sample No. 6, the sample with 5% chickpea flour, 10% bean flour, and 30 g of sugar beet powder, had the best organoleptic indicators. It is evenly light golden in colour, smooth in shape, undamaged, and well cooked. The taste and smell are sweet and are not inferior to the control sample in all parameters. Moisture content, water absorption properties, ash, acidity, fat, vitamins, toxic elements, and microbiological indicators were determined from the physicochemical parameters. Analysing the research results, gingerbread product No. 6 was the optimal regimen, because it contained a high amount of mineral elements and vitamins, and no toxic elements or microbiological indicators were found. In addition, the density and water absorption were relatively close to the control sample.

Published: June 2023

Elderly individuals are often affected by osteoporosis and have poor stability after fracture reduction. Moreover, there is still controversy regarding the clinical effects of the treatment for unstable intertrochanteric fractures in the elderly. The Cochrane, Embase, PubMed, and other databases were searched, and a meta-analysis of the literature on the treatment of unstable intertrochanteric fractures of the elderly with InterTan, PFNA, and PFNA-II was conducted. Seven studies were screened, with a total of 1236 patients. Our meta-analysis results show that InterTan is not significantly different from PFNA in terms of operation and fluoroscopy times, but it takes longer than PFNA-II. In terms of postoperative screw cut, pain, femoral shaft fracture, and secondary operations, InterTan is superior to PFNA and PFNA-II. Conversely, in terms of intraoperative blood loss, hospital stay, and postoperative Harris score, there is no significant difference between InterTan and PFNA and PFNA-II. Compared to PFNA and PFNA-II, InterTan internal fixation has advantages in the treatment of unstable intertrochanteric fractures in elderly individuals in terms of screw cutting, femoral shaft fractures, and secondary operations. However, InterTan operation and fluoroscopy times take longer than PFNA and PFNA-II.
ЛІТЕРАТУРНО-ФОЛЬКЛОРНІ КОРЕЛЯЦІЇ В ДИТЯЧИХ ОПОВІДАННЯХ ВОЛОДИМИРА ВИННИЧЕНКА
Authors: КОБЗЕЙ Н. В.
Published: June 2023

У дослідженні проаналізовано дитячі оповідання Володимира Винниченка – українського автора першої половини ХХ століття. Творам для маленьких читачів він присвятив збірку оповідань «Намисто». У ній чи не вперше основну увагу зосередив на психологічному стані персонажів, їх внутрішньому світі, тому дослідники називають її новаторською. Встановлено, що в аналізованих нами творах автор активно використовував фольклорні мотиви, жанри і образи. Це дозволило йому пояснити читачам деякі народні традиції наших предків, показати нерозривність зв’язку між минулим і сучасним, відтворити колорит епохи, яку він описував. Визначено, що для української культури характерні вірування в існування надприродних істот – відьом, бісів, чортів, русалок, домовиків, чаклунів, перевертнів, які можуть допомагати або шкодити людям. Винниченко запозичує із фольклору образ домовика і лісовика. Здійснено глибокий аналіз цих образів на рівні міфології, фольклору та літератури і звернено увагу, що останній (лісовик/Корчун) зазнав у оповіданні найбільшої літературної трансформації. Проведено паралелі із типологічно спорідненими образами у світовій культурі. Відзначено роль казкотерапії. З’ясовано функції фольклорних елементів у творах: навколо них будується композиція оповідань, через відношення до фольклорних образів проявляються характеристики головних персонажів і втілюються в життя ідейноестетичні концепції автора. А у стресових ситуаціях, пов’язаних з їх появою, формується свідомість маленького індивіда. У своїх творах Винниченко надсилає важливі меседжі до всіх батьків: нашим дітям не потрібна гіперопіка, вони хочуть і можуть бути самостійними. Від нас їм потрібне розуміння і виховання. Не останню роль у формуванні життєвої позиції дитини відіграє народна творчість. Не важливо, у «чистому вигляді», чи в літературній інтерпретації. Головне, що у ній зібрані головні життєві настанови: про добро і зло, етику і мораль, цінності та ідеали, без яких дуже важко в сучасному світі.
Group Dominance, System Justification, and Hostile Classism: The Ideological Roots of the Perceived Socioeconomic Humanity Gap That Upholds the Income Gap
Authors: Sainz Mario , Jiménez-Moya Gloria
Published: June 2023

Perceiving low-socioeconomic status (low-SES) groups as less human than high-SES groups contributes to justifying socioeconomic inequality. Despite this issue’s relevance, previous research has not acknowledged the possible causes of this perceived humanity gap (differences in humanity between SES groups). In this project, we focus on analysing the possible influence of hierarchy-enhancing ideological variables on this gap. To do so, in a first correlational study (N = 765), we analyse the extent to which certain ideological variables predict the perceived humanity gap between low- and high-SES groups. Our results indicate that group dominance, system justification, and hostile classism are highly predictive of the humanity gap. In a second correlational study (N = 521) we found that the perceived humanity gap, the tendency to blame low-SES groups and praise high-SES groups for their economic standings, sequentially mediated the relationship among social dominance, system justification, and hostile classism with the support of social change policies. Finally, we manipulated each ideological variable in three equivalent studies (N = 631) to test its influence on the previous pattern of mediational results. The results confirmed the ideological variables’ antecedent roles in the mediation analysis. Finally, we discuss the role of the ideological hierarchy variables in the maintenance of socioeconomic differences through (de)humanisation.
Analysis of New Type of Second-order Fractional Linear Multi-step Method with Improved Stability
Authors: Nasir H.M.
Published: June 2023

We present and investigate a new type of implicit fractional linear multi-step method of order two for fractional initial value problems. The method is obtained from the second-order superconvergence of the Grünwald-Letnikov approximation of the fractional derivative at a non-integer shift point. The method coincides with the backward difference method of order two for the classical initial value problem when the order of the derivative is one. The weight coefficients of the proposed method are obtained from the Grünwald weights and are hence computationally efficient compared with that of the fractional backward difference formula of order two. The stability properties are analyzed and it is shown that the stability region of the method is larger than that of the fractional Adams-Moulton method of order two and the fractional trapezoidal method. Numerical results and illustrations are presented to justify the analytical theories.

Application of Visual Media Pop-Up Book in English Learning in Elementary School
Authors: Rorimpandey Rinny
Published: June 2023

It is good if English has been introduced since childhood to Indonesian children so that it will not become a frightening specter for them later. In the 2013 curriculum, elementary schools do not have English as a subject, because English has always been a local content subject. However, the obstacle in teaching English is that there are still many elementary school students who are not interested in this subject. The reason is that English is a new language for them and they don't have sufficient vocabulary mastery. Because of that, during English lessons, the teacher teaches only a few students who pay attention, there are many students who play, they feel bored and unenthusiastic when learning English. This was faced by students of the SD GP in Raanan Baru Village, Motoling District, causing them to be unenthusiastic and less creative when it came to English lessons. Therefore, teachers must pay attention to learning models that are appropriate to their goals, not boring but can motivate students and attract their attention, namely choosing learning media can help improve vocabulary mastery. Therefore, in this study, the writer used Visual media pop-up book to improve English vocabulary mastery of the students of SD GP Raanan Baru. The results of this study showed a significant difference, namely the results of the post-test were better than the pre-test as evidenced by the average post-test (T2) score of 71.2 with a standard deviation of 13.5, while the average value of the pre- test (T1) is 30 and the standard deviation is 11.1

Published: June 2023

This study explores the market linkages in a typical agroforestry value chain in Bangladesh, particularly the participation of the micro and subsistence level farming and household-community units in this chain. The study area is Dumuria Upazila which is a 30 square km land area in the outskirt of Khulna which is the third largest city of Bangladesh located in the south-western region of Bangladesh. Agro-products produced in the Dumuria Upazila and then sold in the areas including Dumuria Bazar and Gollamari Bazar which are peri-urban locations of Khulna city. The particular objectives of this study were to identify different value chains of agroforestry products, the relationship of various intermediaries within it, and to explore the impact of agroforestry practices on the socioeconomic condition of the local population. The assessment was performed by using multistage sampling of 80 households using a semi-structured questionnaire, and 30 intermediaries were included on convenience basis for tracing the structure of market linkage and existing problems, in the marketing of agro-products in the study area.  Explored network structures of the value chain have revealed that both the marketing of agroforestry crops and timber, include the intermediaries that have contributed to different forms of value-addition to the original product and produced higher gains for the participants in the value chain. Value chain participants in the point of origin of the products, farmers and households, reported being discriminated in terms of price taking while end-market intermediaries were found to absorb major shares of the total gain originated in the value chain.  The farmers were neutral in terms of satisfaction in case of purchase by the government, while the intermediaries were dissatisfied with the same. Findings of this study contributes in generating understanding the process of value creation, power structure, and gain sharing in the localized natural resources-based value chains.
More than Gold: Embodying the Human Cost of Mining in Maroon Popular Music
Authors: Campbell Corinna
Published: June 2023

Maroons (descendants of Africans who escaped enslavement) have long been locked in an antagonistic relationship with the Surinamese government over gold-mining legislation and its reinforcement. This contentious topic includes complex debates over land rights and conflicting economic and environmental priorities. This article considers how three contemporary Maroon popular musicians have gone beyond stock metaphors about gold to reference local engagements with gold and the gold-mining industry. I introduce the concept, performative figuring, as a strategy whereby a speaker or performer uses their embodied presence to assert their rights and/or self-worth against practices and policies that threaten to undermine them.

Using cell phone blocking apps is an effective way to prevent distracted driving. This study used a high-fidelity driving simulator to examine drivers’ behavior while using a cell phone blocking app. Thirty-five participants drove in a simulated network under four scenarios. Participants also completed pre- and post-survey questionnaires. The results support previous investigations regarding interactions with phones while driving. Results showed that drivers deviated from the center of the road, changed lanes significantly more often, and increased their steering velocity when drivers were interacting with a cell phone. The impacts of cell phone blocking apps were similar to the no distraction scenario while driving. This suggests that using cell phone blocking apps is one of the most effective ways to prevent distracted driving. Survey results indicated that only 23% of drivers used cell phone blocking apps before the experiment. However, 88% of the participants had a positive opinion about using these apps and indicated that they would use such apps after the experiment. These findings support the importance of cell phone blocking apps from a policy perspective and highlight the need to educate drivers about distracted driving prevention technologies.

Social Media Influencer in Hospitality: Literature Review and Proposals
Authors: Wang Hao
Published: June 2023

The COVID-19 has had a significant impact on hospitality marketing, and hospitality marketing strategies urgently need to change to meet the current challenges. The epidemic, on the other hand, has caused people to pay more and more attention to social media, which has increased the prominence of social media influencers (SMI) in this industry. In addition, it is becoming increasingly common for many companies to use influencer marketing as a new development strategy. Therefore, in this context, this article reviews the literature on SMI in hospitality and identifies significant thematic research directions. The study finds two primary thematic directions currently being researched by scholars: External Influence Mechanisms of SMI and Intrinsic Properties of SMI. However, there is less research on the thematic directions of "Psychological-related influential factors and consumer outcomes" and "Strategic assessment of SMIs as a marketing tool". Therefore, the author proposes new research ideas for scholars' reference. At the same time, this study puts forward new ideas for developing hospitality marketing in the post-epidemic era.

Effectiveness Analysis of Stock KDJ Indicator Method based on K-means Clustering
Authors: Qin Linhui
Published: June 2023

The application of data mining technology expands various techniques in stock investment. Among them, cluster analysis is one of the common means to study stock technical indicators. There is a problem in the current cluster analysis of stock technical indicators -- the lack of validation of large-scale stock technical indicators data sets. Most of them are suitable for the comprehensive analysis of technical indicators of a single stock or multiple stocks. Aiming at this problem, this paper takes "the validity analysis of the large-scale stock KDJ index set method based on K-means clustering" as the theme. Firstly, the k-means clustering algorithm was used to construct a deep analysis model (KDJ-k-means) for the KDJ index set of the Shenzhen Index component data group. Secondly, the K, D and J index sets of 2697 constituent stocks of Shenzhen Composite Index are analyzed experimentally. Finally, the results of integrated data mining are obtained. The KDJ-k-means model is an optimization scheme based on the KDJ index set using clustering technology, which provides an intuitive and efficient visual application for deep analysis of large-scale stock data groups.

This article discusses the impact of influencer marketing in the Chi-nese market. Due to the rapid growth of online shopping, influencer promotion has become an important marketing method in the Chinese market. The leading social media in China are Douyin, Red Book, and WeChat. And all of this software comes with an online shopping mall component. The presence of Taobao has also made online shopping more convenient. Social media professionals often have their shops on Taobao. We surveyed consumers of all ages across China using a ques-tionnaire and obtained a sample of 241. The questionnaire was de-signed to compare the impact of online marketing and celebrity en-dorsement on consumers in the Chinese market. Our survey showed that Chinese consumers are likelier to choose products promoted by internet celebrities, with female consumers being the majority. And the majority prefer beauty and garment products. Based on the ques-tionnaire analysis, it can be concluded that influencer marketing is more prevalent in the Chinese market. Due to the development of technology, people do not need to go to offline shops to buy products. Online shopping is more convenient for consumers. And influencer promotion just makes up for the lack of online shopping. Influencer demonstrations of products allow consumers to visualize the effec-tiveness of the products and thus feel confident in their purchases. This is also the reason why most consumers choose influencer market-ing.

Financial crisis forecasting (FCP) plays a crucial role in economic phenomena. An accurate forecast of the number and likelihood of failures indicates the growth and strength of a country's economy. Traditionally, several effective FCP methods have been proposed. On the other hand, classification performance, prediction accuracy, and data legitimacy are not good enough for practical applications. In addition, many developed methods perform well for some specific datasets but do not apply to different datasets. Therefore, there is a need to develop an effective prediction model to obtain better classification performance and to adapt to other datasets. In this paper, we improve the data characteristics of the existing methods, including introducing time series variables, macroeconomic indicators interaction terms, etc. Finally, this paper attempts to predict financial crises using logistic regression models. The analysis of the results ensures that the proposed FCP model outperforms other classification models based on different metrics and explores the essential factors affecting financial crises.
