Impact of Climate Change on Flowering Phenology and Abundance on Mertensia spp.
Authors:   College of Agriculture, University of Sargodha, Pakistan, Saad Umar Muhammad , Hayat Hafiza Mubeen
Published: November 2023

This research article delves into the intricate dance between climate change and two enchanting flower species, Mertensia fusiformis and M. ciliata. These blossoms, with their nodding blue petals and elegant foliage, grace the Great Basin and alpine meadows. However, their delicate beauty conceals a resilient spirit, tested by the relentless forces of climate change. We explore the physiology of these flowers, uncovering the influence of rising temperatures on their flowering patterns. M. fusiformis tends to bloom earlier, adapting to shifting climatic cues. In contrast, M. ciliata shows variations in flower size and coloration. The consequences of climate change ripple through these species' distribution and habitat suitability. Warmer temperatures propel M. fusiformis to higher elevations, where it faces new challenges and competition. M. ciliata experiences habitat loss as alpine treelines ascend, pushing it into crevices and microclimates. These flowers' pollination mechanisms also adapt to changing conditions, with shifts in pollinator behavior and abundance disrupting their age-old partnerships. Conclusively, climate change orchestrates a captivating yet disquieting symphony in the lives of Mertensia fusiformis and M. ciliata. They stand as messengers, urging us to acknowledge the fragility of our ecosystems and take action to preserve the beauty of our planet's flora.

Perlindungan Hukum Bagi Konsumen Pengguna Tenaga Listrik Pascabayar Atas Pengalihan Biaya Secara Sepihak Oleh Pt. Pln (Persero)
Authors: Chusnah Syarifah , Wahjuni Edi , Adonara Firman Floranta
Published: November 2023

Pandemi Covid-19 membuat PT. Perusahaan Listrik Negara (PT. PLN) menerapkan kebijakan pembayaran tagihan listrik pasca bayar dengan sistem perhitungan rata-rata pemakaian 3 bulan terakhir dan membebankan kelebihan daya pada bulan berikutnya. Kebijakan pengalihan biaya ini dilakukan secara sepihak, serta berimbas buruk pada rumah tangga, pengusaha kecil hingga industri besar. PT. PLN berdalih bahwa kebijakan Pembatasan Sosial Berskala Besar (PSBB) membuat pelaku usaha tidak dapat melakukan pemeriksaan KWH meter. Namun dalih tersebut tidak dapat dibenarkan, mengingat pada saat PSBB, sektor layanan dasar tetap berjalan, termasuk sektor layanan listrik. Lebih lanjut, realitas ini dapat dikatakan sebagai bentuk bisnis yang tidak lazim. PT. PLN dianggap telah lalai melaksanakan tugasnya dalam melakukan pencatatan meteran pada pengguna tenaga listrik pasca bayar. Terlebih, PT. PLN tidak memberikan informasi kepada konsumen tentang adanya kebijakan ini. Puncaknya, fenomena ini memberikan ketidakadilan pada konsumen. Topiknya adalah konsumen mengalami kerugian akibat tidak adanya informasi atas pengalihan biaya tenaga listrik pascabayar yang dilakukan PT. PLN (Persero) secara sepihak. Sehingga konsumen mencari upaya penyelesaian sengketa untuk mendapatkan hak-hak sebagai konsumen dan mendapatkan perlindungan hukum.

The wide potential of resin acids as bioactive agents gave rise to a growing effort in the search for new applications of the natural forms and semisynthetic agents [1]. From the other hand, chromenes are widespread in natural products and have attracted much attention from a researchers in medicinal chemistry [2]. From the point of view of bioactivity, the hybrid system of 1,2,4-triazol and chromenol is an interesting subject for study [3].To obtain the co-crystalline particles of dehydroabietinic acid and 2-tert-butyl-3-(1H-1,2,4triazol-1-yl)-2H-chromen-2-ol, two different sets of conditions were tried: co-precipitation and the kneading method, which is relatively simple and consists of precisely weighing the acid and chromen 1, stirring and grinding them in the dry phase for a few minutes, followed by the addition of some H2O. The mixture of dehydroabietic acid and 2-tert-butyl-3-(1H-1,2,4-triazol-1-yl)-2H-chromene-2-ol becomes a paste that has been triturated for 1.5 hours and finally resulting product is dried. The antifungal activity of dehydroabietic acid, 2-tert-butyl-3-(1H-1,2,4-triazol-1-yl)-2Hchromene2-ol and microparticulate system was evaluated against different species: Candida albicans, Saccharomyces cerevisiae. Aspergillus fumigatus, A. versicolor, A. ochramensis, Trichoderma viride respectively. All the tested compounds exhibited good antifungal activity which was higher compared to the parent components and reference drugs (ketoconazole and bifonazole).

Authors: Pogrebnoi Vsevolod , Sucman Natalia , Macaev Fliur
Published: November 2023

The abstract presents the synthesis of new spiropyranes from substituted 5-aminoisatin 6 in multicomponent reaction with different carbonyl compounds. It is known that spiropyranes have various activities, which depend from spatial structure and substituents [1]. From the other side, previously mentioned dehydroabietic acid 1 [2] is interesting object to study due to its molecular structure, chemical and biological properties.Initially, our strategy was to obtain the substituted isatine 6 from easily accessible isatine 3. To implement that approach, previously obtained [2] 5-nitroisatine reacted with fivefold excess of ethylene glycol [3] using 10 mol% p-toluenesulfonic acid in boiling toluene to give 4 in good yield. Next, the obtained dioxalane 4 was introduced into the reduction reaction, where the best yield was reached using the fivefold excess of tin (II) chloride [3] as reducing agent. The amidation reaction between 5-aminodioxalane 5 and chloride 2 took place in dry chloroform, using as acceptor the moderate excess Et3N [3]. During the deprotecting essay of dioxalane cycle [3] the best conditions were aqueous acetone (1:3) and 96% sulfuric acid at 350C, leading to desired isatine 6 with 75% yield. The final stage was famous three component reaction [4] between the desired isatine 4, malononitrile and carbonyl compound. The first example [3] started from pyrazoline-2-one, yielded 57% the desired compound 7. Another carbonyl compound – acetoacetic ester gave the compound 8 with 66% yield [3]. But in case of 2,4-pentanedione the reaction haven’t succeeded in different conditions selection (various solvents and long-term boiling).

Authors: Koceva Ana , Kostadinova Dafina , Tabutova Tanya
Published: November 2023

For decades English has been considered a global language used as not only a native language, but as an official language, a second language in many countries and taught as a foreign language worldwide. Herein, English includes numerous varieties, regional and local dialects, professional speech, slangs, jargons etc. The variety of English is an important feature for learners of EFL, especially for future teachers of English. The constant exposure to different types of English through television, movies, online content etc. might hinder the fluency of EFL learners. Therefore, EFL teachers need to help their students and prevent any ambiguities due to the differences between American and British English. In this research, we have analysed the preference of students between British English and American English vocabulary. The analysis includes 60 first year students of English language and literature from the University “Goce Delcev” in North Macedonia and the South-West University in the Republic of Bulgaria. The results provide an insight on both the knowledge and linguistic preference of students between the two standardized English varieties and enable teachers, university professors and English coursebooks authors to determine their approach in class and help students master fluency.

Objectives. The study aimed to assess the relationship of tinnitus with hyperacusis with cognitive impairment as indicated by the Montreal Cognitive Assessment (MoCA) tool.Methods. This multicenter cross-sectional study included individuals with chronic tinnitus from the “Unification of Treatments and Interventions for Tinnitus Patients” (UNITI) database. Participants were recruited from four different tertiary clinical centers located in Athens and Granada (Mediterranean group), as well as Berlin and Regensburg (German group). In total, 380 individuals with a diagnosis of non-pulsatile chronic tinnitus (permanent and constant tinnitus lasting more than 6 months) and no evidence of severe cognitive impairment (MoCA score >22) were enrolled. The evaluation utilized the following tools: MoCA, Tinnitus Handicap Inventory (THI), Hyperacusis Questionnaire (GÜF), Patient Health Questionnaire (PHQ-9), and the European School for Interdisciplinary Tinnitus Research Screening Questionnaire.Results. MoCA scores differed between German and Mediterranean individuals (P<0.01), necessitating separate analyses for each group. In both cohorts, MoCA scores were significantly associated with education level, age, hearing threshold at 8 kHz, and THI. Furthermore, a significant correlation was observed between PHQ-9 scores and both THI and GÜF (P<0.01 for both Germans and those from the Mediterranean).Conclusion. Our data suggest an association between tinnitus handicap, high-frequency hearing loss, and mild cognitive impairment. Additionally, PHQ-9 scores were associated with tinnitus and hyperacusis scores, independent of hearing loss thresholds.

Authors: Thompson Paul Wesley
Published: November 2023

COVID-19 has drastically impacted care home residents, families, and staff. However, little is known about the impact of this pandemic on carers from the ethnically minoritised background. The present research explored the experiences of UK’s black carers during COVID-19. A semi-structured interview-based qualitative study was conducted involving black carers from Berkshire, Hampshire, and Oxfordshire. Interviews were conducted online through Microsoft Teams, and a thematic analysis was performed on verbatim transcribed interviews. The present study included 15 participants from three UK counties which have a large number of care homes. The analysis of interviews resulted in the development of seven themes: 1) reactions to COVID, 2) infection control in the work environment, 3) workplace discrimination, 4) impact of COVID on well-being, 5) coping mechanisms and impact of deaths, 6) reflection on challenges, and 7) recommendations to care home managers. In conclusion, the black carers reported a substantial impact on their mental and physical health. They recognized the need for timely information, sufficient and fair availability of PPEs, more support, better communication, and equitable work distribution to maintain their mental and physical health.

Published: November 2023

Efficient utilization of galactose by microorganisms can lead to the production of valuable bio-products and improved metabolic processes. While Bacillus subtilis has inherent pathways for galactose metabolism, there is potential for enhancement via evolutionary strategies. This study aimed to boost galactose utilization in B. subtilis using adaptive laboratory evolution (ALE) and to elucidate the genetic and metabolic changes underlying the observed enhancements. B. subtilis strains were subjected to successive rounds (~ 5000 generations) of ALE under conditions promoting galactose utilization with a higher specific growth rate of 0.319 h-1 compared to wild type (0.03 h-1). Resultant evolved strains, BSGA14 was analyzed for their galactose conversion rates. After genome resequencing, 63 SNPs were identified in BSGA14 strain. Two of them, located in the coding sequences of the genes araR and glcR, were found to be the advantageous mutations after reverse engineering. The strain with these two accumulated mutations, BSGALE4, exhibited similar specific growth rate on galactose to the evolved strain BSGA14 (0.296 h-1). Furthermore, evolved strain showed higher productivity of protease and β-galactosidase in mock soybean biomass medium. ALE proved to be a potent tool for enhancing galactose metabolism in B. subtilis. The findings offer valuable insights into the potential of evolutionary strategies in microbial engineering and pave the way for industrial applications harnessing enhanced galactose conversion.
EDEN: Learning Deterministic Node Position with Equivariant Distance Encoding
Authors: Liu Chang , Yang Yuwen , Ding Yue , Lin Wenqing , Lu Hongtao
Published: November 2023

Despite Graph Neural Networks' (GNNs) achievements in graph representation learning tasks, how to learn the deterministic node position embedding in non-Euclidean graph data is still an open question. Additionally, most existing message-passing-based graph neural networks' expressive power is commonly limited by the 1-Weisfeiler-Lehman (1-WL) graph isomorphism test. Many works have recently proposed different ideas to solve the above two problems separately. However, they cannot guarantee all-level tasks generalization, intense expressiveness, and efficient reasoning on all graph tasks simultaneously.In this work, we connect these lines of inquiry to propose a plug-in Equivariant Distance ENcoding (EDEN). EDEN is derived from a series of interpretable transformations on the graph's distance matrix. We theoretically prove that EDEN is permutation-equivariant for all level graph learning task generalization, and we empirically illustrate that EDEN's expressive power can reach up to the 3-WL test. Extensive experiments on real-world datasets show that combining EDEN with conventional GNNs surpasses recent advanced GNNs and position encodings at the same or lower computational complexity.

Authors: Hurtado Daniel , Contreras–Briceño Felipe , Cancino Jorge , Espinosa-Ramirez Maximiliano , Fernandez Gonzalo , Johnson Vader
Published: November 2023

Ventilatory thresholds (VTs) are key physiological parameters to evaluate physical performance and determine aerobic and anaerobic transitions during exercise. Current assessment of these parameters requires ergospirometry, limiting the evaluation to laboratory or clinical settings. In this work, we introduce a wearable respiratory system that continuously tracks breathing during exercise and estimates VTs during ramp–tests. We validate the respiratory rate and VTs predictions in 17 healthy adults using ergospirometry analysis. In addition, we use the wearable system to evaluate the VTs in 107 recreational athletes through ramp tests outside the laboratory and show that the mean population values agree with previous studies in large groups. We envision that respiratory wearables can be useful in determining aerobic and anaerobic parameters outside clinical setting with promising applications in health telemonitoring and human performance.

Published: November 2023

Purpose
There is still currently a lack of magnetic resonance imaging (MRI) based radiomics analysis in the prognosis model for patients with nasal extranodal natural killer/T-cell lymphoma (ENKTL). We aim to investigate the value of MRI-based radiomics signature in the prognosis for patients with nasal ENKTL.
Methods
159 nasal ENKTL patients were enrolled and divided into a training cohort (n = 81) and a validation cohort (n = 78) randomly. Radiomics features from pretreatment MRI examination were extracted respectively. Then two sample t-test and least absolute shrinkage and selection operator (LASSO) regression were used to select the radiomics signatures and establish the Rad-score. A radiomics nomogram based on the Rad-score and clinical features was constructed to predict overall survival (OS).
Results
The radiomics model that integrated Rad-score and clinical risk factors exhibited a satisfactory prediction performance compared with the Rad-score and clinical models in terms of OS in the training cohort (C-index: 0.849 vs. 0.733 vs. 0.707, AUC: 0.896 vs. 0.767 vs.0.798). For validation, the C-index of the three models was 0.931 vs. 0.824 vs. 0.635 respectively. Moreover, the AUC was 0.839 vs. 0.827 vs. 0.583 respectively. The calibration curves also suggested that the net benefit of radiomics models was higher than that of the Rad-score and clinical models.
Conclusions
The Rad-score was significantly correlated with OS for nasal ENKTL patients. Moreover, the MRI-based radiomics nomogram could be used for risk stratification and provide personalized treatment plans for patients.
WITHDRAWN: Emotion Detection in Arabic Short Text: A Deep-Learning Approach
Authors: Aljwari* Fatima , Zamzami Nuha
Published: November 2023

In modern society, writing down thoughts, ideas, and pleasant experiences has become a widespread way to express feelings. X, formerly known as Twitter, is a rich data source that companies can use to study individuals’ ideas, thoughts, and emotions for a range of useful applications. The analysis of positive and negative feelings is a key focus of NLP research literature, while emotion detection receives relatively little attention. Very few studies to date have examined the classification of emotions in text, particularly Arabic written content. The new study uses deep learning approaches to solve this difficulty and close these existing gaps in the literature. A number of different deep learning models are available and each one has been developed based on a unique feature engineering approach to classify the emotions conveyed in the SemEval-2018 dataset into four groups, namely joy, fear, anger and sadness. The results show that the CNN model that employs Word2vec outperforms the other models, with an accuracy of 80%. Furthermore, it has been found to perform better in Arabic than the most current comparable model, with improvements varying between 12–54.96% for F1 scores to 5–26% for accuracy.

Assessment of Blast Loading on Buildings
Authors: Kumar Munish , Roy Amrit Kumar
Published: November 2023

This paper uses a CFD-based technique for simulating vapour cloud explosion. A firm full­ scale CFD model was developed for the building and LPG gas tank. This study also showed how the dispersion and combustion of an average cloud, formed during a spill into a liquefied petroleum gas tank could be simulated. The performance of this simulation allows assessment of the overpressure resulting from the burn of the flammable gas cloud. The objective of this study is therefore to assess different turbulence models against actual experimented measurements to evaluate their suitability in modelling dense vapour dispersion. CFD models showed that controlling variables include release surface area, wind speed, turbulence, and nearby obstructions.
Fluctuation-response relations for integrate-and-fire models with an absolute refractory period
Authors: Puttkammer Friedrich , Lindner Benjamin
Published: November 2023

We study the problem of relating the spontaneous fluctuations of a stochastic inte\-grate-and-fire (IF) model to the response of the instantaneous firing rate to time-dependent stimulation if the IF model is endowed with a non-vanishing refractory period and a finite (stereotypical) spike shape. This seemingly harmless addition to the model is shown to complicate the analysis put forward by Lindner Phys. Rev. Lett. (2022), i.e. the incorporation of the reset into the model equation, the Rice-like averaging of the stochastic differential equation, and the application of the Furutsu-Novikov theorem. We derive a still exact (although more complicated) fluctuation-response relation (FRR) for an IF model with refractory state and a white Gaussian background noise. We also briefly discuss an approximation for the case of a colored Gaussian noise and conclude with a summary and outlook on open problems.
Perspective: There is Plenty of Room for Magnetic Straintronics in the Analog Domain
Authors: Bandyopadhyay Supriyo
Published: November 2023

Magnetic straintronics made its debut more than a decade ago as an extremely energy-efficient paradigm for implementing a digital switch for digital information processing. The switch consists of a slightly elliptical nano-sized magnetostrictive disk in elastic contact with a piezoelectric layer (forming a two-phase multiferroic system). Because of the elliptical shape, the nanomagnet’s magnetization has two stable (mutually antiparallel) orientations along the major axis, which can encode the binary bits 0 and 1. A voltage pulse of sub-ns duration and amplitude few to few tens of mV applied across the piezoelectric generates enough strain in the nanomagnet to switch its magnetization from one stable state to the other by virtue of the inverse magnetostriction (or Villari) effect, with an energy expenditure that is roughly an order of magnitude smaller than what it takes to switch a modern-day electronic transistor. That possibility, along with the fact that such a switch is non-volatile unlike the conventional transistor, generated significant excitement. However, it was later tempered by the realization that straintronic switching is also extremely error-prone, which may preclude many digital applications, particularly in Boolean logic. In this perspective, we offer the view that there is plenty of room for magnetic straintronics in the analog domain, which is much more forgiving of switching errors, and where the excellent energy-efficiency and non-volatility are a boon. Analog straintronics can have intriguing applications in many areas, such as a new genre of aggressively miniaturized electromagnetic antennas that defy the Harrington limit on the radiation efficiency of conventional antennas, analog arithmetic multipliers (and ultimately vector matrix multipliers) for non-volatile deep learning networks with very small footprint and excellent energy-efficiency, and relatively high-power microwave oscillators with output frequency in the X-band. When combined with spintronics, analog straintronics can also implement a new type of spin field effect transistor employing quantum materials such as topological insulators, and they have unusual transfer characteristics which can be exploited for analog tasks such as frequency multiplication using just a single transistor. All this hints at a world of new possibilities in the analog domain that deserves serious attention.

Much progress needs to be made before the tourism industry achieves high-quality development. Moreover, the upgrading of the tourism industry is the key to the economic transformation and optimization of ethnic minority areas. On the basis of the theory of social reproduction, this article takes “input-process-output” as the logical basis and constructs the tourism industry from eight criteria levels, namely, factor input, innovation input, coordinated development, green development, industrial structure, open development, shared development, and effective development. On the basis of a scientific and comprehensive evaluation index system, this study uses the entropy method and the obstacle model to measure and evaluate the high-quality development level of the tourism industry in western China from 2011 to 2020. The research results show that major public events can have a serious impact on the tourism industry, and the vulnerability of the tourism industry is relatively evident. In addition, the measurement results reveal that advanced industrial structures, openness to the outside world, development quality, driving innovation, improved life quality, labor input, infrastructure, and development efficiency are the main factors restricting the development level of the tourism industry in most provinces in ethnic minority areas. Hence, the study proposes four ways to promote the high-quality development of the tourism industry in these locations. First, a high-level tourism industry structure and large-scale development must be realized simultaneously. Second, open development, green development, and shared development must be vigorously promoted within the tourism industry. Third, the driving role of technological innovation and policy innovation must be emphasized. Fourth, a normalized joint prevention and control mechanism for the tourism industry must be established.
Efficiency and Equilibrium Selection in Arbitrated Bargaining
Authors: Han John J. , Haruvy Ernan
Published: November 2023

We study two variants of an arbitrated bargaining problem where two parties lay proportional claims to an asset, and an arbiter has a final say on allocation. The two variants we study vary by the incentives to the arbiter. In one variant, the arbiter is incentivized proportional to the payoff to the lowest paid claimant and in the other, the arbiter is incentivized proportional to the payoff to the highest paid claimant. While neither incentive scheme alters the set of equilibria, they alter expected payoff in off-equilibrium outcomes, and therefore impact equilibrium selection. Accordingly, the first variant leads to egalitarian claims whereas the second variant leads to greedy claims and subsequently to a high incidence of impasse.

Welsh clausal i and the hierarchical lexicon
Authors: Borsley Robert D.
Published: November 2023

A number of types of Welsh subordinate clause are introduced by what looks like the preposition i `to', `for'. Earlier research has shown that there are three different lexemes here. It is not unusual for a language to have homophonous lexemes, but these lexemes share a variety of properties, and also share properties with the preposition i. The similarities and the differences among these lexemes can be captured if they are grouped together as four different realisations of a single `super-lexeme' within the hierarchical lexicon.
Morphotactic competition in Murrinh-Patha: Rule composition and rule interaction in Information-based Morphology
Authors: Crysmann Berthold
Published: November 2023

Murrinh-Patha, a
polysynthetic Non-Pama-Nyungan language of Australia features
competition of subject and object agreement markers for a particular
position (i.e. slot 2), meaning that certain subject agreement markers
are realised in this position, unless already occupied by overt object
agreement markers. In their typology of variable morphotactics,
Crysmann & Bonami (2016) cite the case of Murrinh-Patha as an instance
of misaligned, conditioned placement. I shall propose a formal account
of this positional competition in Murrinh-Patha within
Information-based Morphology. To this end, I shall generalise the
“pivot” features previously proposed for placement relative to the
stem (Italian; Crysmann & Bonami, 2016) or the edge (Sorani Kurdish;
Bonami & Crysmann, 2013; Salehi & Koenig, 2023) and show how this will
facilitate the treatment of conditioned placement in Murrinh-Patha.
Generation of MRS Abstract Predicates from Paninian USR
Authors: Sukhada Sukhada , Hymavathi Sirisipalli Veera , Paul Soma
Published: November 2023

Semantic Representations become useful resources for various multilingual NLP applications such as Machine Translation, Multilingual Generation, cross Lingual QA, to name a few. No Semantic Representation, to our knowledge, adopts vivakṣā (Speaker’s intention) as a guiding principle for the representation. This motivates us to develop a new Semantic Representation system – Universal Semantic Representation (USR) – following Indian Grammatical Tradition (IGT) and Paninian grammar. Since USR is designed to be language-independent, we have currently taken up the task of generating English, Hindi, Tamil and Bangla from the USR. For English generation, the USR is mapped to ERG meaning representation (Flickinger, D. 1999) which is couched in Minimal Recursion Semantics (MRS). We use an off-the-shelf ACE generator that uses ERG as a resource-grammar for generating English. While designing the transfer module from USR to ERG-based MRS, we came across various Abstract Predicates (APs) in MRS representation as described in ErgSemantics_Basic (Flickinger et al., 2014). These APs are used to represent the semantic contribution of grammatical constructions or more specialized lexical entries such as compounding or the comparative use of more and so on. This paper presents the strategy for postulating the APs from the information given in USR and then reports the implementation of the transfer module keeping the focus on the postulation of APs. We get around 95% accuracy in postulating APs from USR.
Further evidence for an HPSG-based theory of the semantics of different and the same
Authors: Yatabe Shûichi
Published: November 2023

Yatabe (2021) presents a theory according to which the meaning of a word like different in a sentence like Anna and Bill like different films contains the meaning of a reciprocal pronoun. Since the postulated reciprocal meaning inside the meaning of a word like different requires the presence of a semantic antecedent, the theory entails that the apparent internal reading of a sentence like John saw and reviewed different films, which does not contain a plural DP that could serve as the semantic antecedent of the postulated reciprocal meaning, must be licensed in a way that is entirely different from the way in which the internal reading of a sentence like Anna and Bill like different films is licensed. In the present paper, I adduce additional pieces of evidence for this theory. In order to enhance the plausibility of the proposed theory, I also show how the collective interpretation of reciprocals and the interaction of reciprocals and cumulative interpretation can be accounted for within the theory.
Robust optimization method of emergency resource allocation for risk management in inland waterways
Authors:   Wuhan University of Technology, Wuhan, China, Ma Quandang
Published: November 2023

This study proposes a robust optimization method for waterborne emergency resource allocation in inland waterways that addresses the uncertainties and mismatches between supply and demand. To accomplish this, we integrate the risk evaluation of maritime with a robust optimization model and employ the Entropy Weighted Method (EWM)-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)-Analytic Hierarchy Process (AHP) method to evaluate the risk of various areas. The approach enables exploration of the relationship between maritime risk and emergency resource allocation strategy. The robust optimization method is used to deal with uncertainty and derive the robust counterpart of the proposed model. We establish an emergency resource allocation model that considers both the economy and timeliness of emergency resource allocation. We construct an optimization model and transform it into an easily solvable robust counterpart model. The results demonstrate that the proposed method can adapt to real-world scenarios, and effectively optimize the configuration effect while improving rescue efficiency under reasonable resource allocation. Specifically, the proportion of rescue time saved ranges from 28.52% to 92.60%, and the proportion of total cost saved is 95.82%. Our approach has significant potential to provide a valuable reference for decision-making related to emergency resource allocation in maritime management.
Virtual small business entrepreneurship opportunities
Authors: Lose Thobekani , Eze Ikenna Franklin
Published: November 2023

For small business entrepreneurs in rural areas to survive in the digital contexts, research is essential on the challenges they face and how these challenges can become opportunities for other entrepreneurs. In this study, small business entrepreneurship opportunities at a township in the Eastern Cape were explored. The basis of the study was that entrepreneurship opportunities are embedded in business challenges and entrepreneurs who can provide services or products that address identified challenges can have viable entrepreneurship ventures. The study used two-phased sequential interviews to collect data to address the purpose of the study, which was: to explore the small business entrepreneurship opportunities in the Eastern Cape in the context of digitalisation. In the first interview challenges, faced by 60 entrepreneurs at an identified small business Mall, were recorded, and the most common challenges were noted. After noting the most common challenges and suggestions for possible business opportunities, associated with addressing the challenges, interviews with eight entrepreneurs in the Mall were then undertaken to gather more information. The study found evidence that small business entrepreneurship opportunities existed in areas related to providing essential support services, such as small business education and training, infopreneurship, and digital infrastructure retailing including providing alternative power options, such as solar power for the enterprises. With the high unemployment and high rate of small business failure, the study recommends the effective exploitation of the identified business opportunities to ensure that existing enterprises survive and new ventures also arise.
