Theoretical Interpretation of pH and Salinity Effect on Oil-in-Water Emulsion Stability Based on Interfacial Chemistry and Implications for Produced Water Demulsification
Authors: Miadonye Adango , Amadu Mumuni
Published: August 2023

The petroleum industry produces thousands of barrels of oilfield waters from the initial stage driven by primary production mechanisms to the tertiary stage. These produced waters contain measurable amounts of oil-in-water emulsions, the exact amounts being determined by the chemistry of the crude oil. To meet strict environmental regulations governing the disposal of such produced waters, demulsification to regulatory permissible levels is required. Within the electric double layer theory, coupled with the analytical solutions to the Poisson–Boltzmann Equation, continuum electrostatics approaches can be used to describe the stability and electrokinetic properties of emulsions. In the literature, much of the surface charge density and zeta potential relationship to emulsion stability has been confined to systems with less salinity. In this paper, we have exploited the theoretical foundations of the electric double layer theory to carry out theoretical evaluations of emulsion salinity based on zeta potential and surface charge density calculations. Most importantly, our approaches have enabled us to extend such theoretical calculations to systems of the higher salinity characteristic of oil-in-water emulsions found in oilfield-produced waters, based on crude oil samples from the literature with varying surface chemistry. Moreover, based on the definition of acid crude oils, our choice of samples represents two distinct classes of crude oils. This approach enabled us to evaluate the stability of emulsions associated with these produced oilfield waters in addition to predicting the potential of demulsification using demulsifiers. Given that the salinity range of this study is that encountered with the vast majority of produced oilfield waters, the findings from our theoretical predictions are perfect guides as far as emulsion stability is concerned.
Research on Path Tracking and Yaw Stability Coordination Control Strategy for Four-Wheel Independent Drive Electric Trucks
Authors: Gao Feng , Zhao Fengkui , Zhang Yong
Published: August 2023

Achieving accurate path tracking and vehicle stability control for four-wheel independent drive electric trucks under complex driving conditions, such as high speed and low adhesion, remains a major challenge in current research. Poor coordination control may cause the vehicle to deviate from its intended path and become unstable. To address this issue, this article proposes a coordinated control strategy consisting of a three-layer control framework. In the upper layer controller design, establish a linear quadratic regulator (LQR) path tracking controller to ensure precise steering control by eliminating steady-state errors through feedforward control. The middle layer controller utilizes the fractional order sliding mode control (FOSMC) yaw moment controller to calculate the additional yaw moment based on the steering angle of the upper input, utilizing the error of yaw rate and sideslip angle as the state variable. To collectively optimize the control system, establish a coordinated optimization objective function and utilize the hybrid genetic-particle swarm optimization algorithm (GA-PSO) to optimize the weight coefficient of LQR and sliding mode parameters of FOSMC, effectively improving the performance of the controller. In the lower layer torque distribution controller, use the quadratic programming method to achieve real-time optimal torque distribution based on tire utilization, which improves vehicle stability control. Through simulations conducted under four different working conditions, the proposed control scheme demonstrates a 15.54% to 23.17% improvement in tracking performance and a 10.83% to 23.88% optimization in vehicle driving stability compared to other control methods. This scheme provides a theoretical reference for path tracking and stability control in four-wheel independent drive electric trucks.

Authors: Li Li , Zhang Xiao , Hu Bin , Lei Shun
Published: August 2023

Recycling of coal resources left behind in goafs and the treatment and utilization of solid waste from mines are topical issues faced by the global coal mining industry at present. With the annual reduction of recoverable reserves of coal resources and the dependence on coal resources that are difficult to replace, the problems have become increasingly prominent, seriously limiting the development of coal resources and the implementation of environmental protection work. The mutual influence between the strength of filling materials and the size of loose coal in the CRRM process through numerical simulation experiments, laboratory rock mechanics experiments, and on-site large-scale similar simulation material experiments is explored. It is ultimately believed that selecting a filling material with a 20 cm particle size of loose coal and a 90% proportion of loose coal for 7 days can meet the requirements of the CRRM process, and this conclusion has been verified through on-site engineering scale experiments. The scientific problems faced by various links in the process of filling and replacing abandoned coal in goafs were analyzed, and improvement methods were further proposed; the technical system of filling and replacing abandoned coal was improved, and new directions for the efficient and safe recovery of abandoned coal resources worldwide in the future were developed.

Published: August 2023

With the continuous progress and application of robotics technology, the importance of mobile robots capable of adapting to specialized work environments is gaining prominence. Among them, achieving precise and stable control of AGVs (Automated Guided Vehicles) stands as a paramount task propelling the advancement of mobile robotics. Consequently, this study devises a control system that enables AGVs to attain stable and accurate motion through equipment connection and debugging, kinematic modeling of the four-wheel steering AGV, and a selection and comparative analysis of motion control algorithms. The effectiveness of the Stanley-PID control algorithm in guiding the motion of a four-wheel steering AGV is validated through MATLAB 2021a simulation software. The simulation results illustrate the outstanding stability and precise control capabilities of the Stanley-PID algorithm.
Cognitive Radio Strategy Combined with MODCOD Technique to Mitigate Interference on Low-Orbit Satellite Downlinks
Authors: Araujo Rodolfo , da Silva Luciano , Santos Walter , Souza Marcelo
Published: August 2023

The concept of cognitive radio (CR) as a tool to optimize the obstacle of spectral coexistence has promoted the development of shared satellite–terrestrial wireless networks. Nevertheless, in some applications like Earth Exploration Satellite Services, which demand high spectral efficiency (bps/Hz) for downlink transmissions, spectral coexistence amidst interferences from cellular Base Stations is still challenging. Our research aims to mitigate these interferences on low-orbit satellite downlinks carrying imaging data received from a ground station. In order to fulfill this, we present cognitive radio approaches to enhance spectrum exploitation and introduce the adaptive modulation and coding (MODCOD) technique to increase RF power and spectral efficiencies. Therefore, we propose a combined methodology using CR and adaptive MODCOD (ACM) techniques. Afterwards, we applied the solution by monitoring the signal to interference plus noise ratio and the MODCOD strategy. Finally, we provide a real in situ case study at the Cuiabá ground station located in Brazil’s central area, which receives images from an Earth observation satellite (EOS). In addition to demonstrating the strategy effectiveness in this scenario, we conducted a bench test emulating the interfering wireless communication system. In this sense, we demonstrated the proposed approach, successfully mitigating the harmful effects on the received EOS images.
Nutrition Education Program Assistants: A Leverage Point for Collecting Authentic Program Data
Authors: McFerren Mary , Franz Nancy , Lambur Michael
Published: August 2023

Extension administrators and educators wonder why low-income audiences refrain from participating or underparticipate in educational opportunities. This may be due to a gap between administrator or educator views of program participation barriers versus the lived experience of low-income audiences. Virginia Cooperative Extension worked to bridge this gap in perspectives by using Nutrition Program Assistants as a leverage point for recruiting and gathering authentic data on program participation from low-income individuals. Even though program assistants rarely serve in this role, their connection with low-income clientele and groups that serve them is invaluable for gathering authentic program data.

Landing mechanism tends to rebound and turn over, and the stability time is long when landing on the small celestial body. Its landing performance in different conditions is necessary to be evaluated to guide the landing. Here, landing performance evaluation is realized by simulation. Key factors affecting the landing performance including cardan element damping, foot anchors, retro-rocket thrust, landing slope angle, and landing attitude are analyzed. A microgravity platform is built to test the landing mechanism, and the consistency between the simulation and the experiment is compared. On the basis of simulation and experiment, some landing suggestions are proposed to improve the landing performance.
KONTEKSTUALISASI DAN RELEVANSI UZLAH DI ERA GLOBALISASI DALAM PANDANGAN ULAMA’

Dizaman modern sekarang ini, seiring dengan semakin majunya zaman, semakin banyak produk-produk elektronik yang canggih. Dengan semakin cangginya teknologi tersebut dunia serasa sempit, semua yang kita inginkan bisa terpenuhi dengan hitungan jam, menit, bahkan hitungan detik. Manusia semakin terbuai dengan kenikmatan duniawi, sehingga tak jarang jika kita temukan kemaksiatan-kemaksiatan diera modern sekarang ini. Seiring dengan semakin majunya zaman, pergaulan juga semakin bebas, tak pandang pria atau wanita yang bukan mahrom bercampur aduk. Dengan semakin bebasnya pergaulan yang tidak dibatasi oleh syariat (agama islam) maka akan menimbulkan rusaknya pergaulan dan meraja lelanya kemaksiatan. Jika kita lihat di era modern sekarang ini, sangat minim sekali orang-orang yang mau menjaga agamanya , serta keimanannya dengan baik dan serius. Dalam mengatasi hal tersebut, satu-satunya cara yang baik  dalam menghadapi era globalisasi sekarang ini ialah dengan melakukan uzlah (menyendiri, menyepi, menghindari, menjauhi serta mengasingkan diri dari pergaulan umumm yang tercela.), karena kualitas keimanan kita menengah kebawah, maka satu-satunya cara untuk menyelamatkan keimanan kita ialah dengan ber’uzlah.

Penelitian ini bersifat kepustakaan (library research), sementara metode yang digunakan adalah studi maudhu’iy/tematik. Proses pengumpulan data dilakukan dengan cara mengumpulkan data-data yang terkait dengan penelitian ini melalui penelitian pustaka. Serta dalam menganalisis kajian ini menggunakan metode tematik, yaitu menghimpun ayat-ayat serta dalil yang berkenaan dengan uzlah dalam pandangan Ulama’ Klasik Hingga kontemporer. Seseorang dalam keadaan ini tidak seperti ber uzlah mengasingkan diri, tetapi membiasakan diri dengan menjaga agar hatinya tidak mengalami kehampaan spritual dan zikir kepada Allah Swt. Hatinya hidup dan mengingat Allah diberbagai kondisi, suasana, waktu dan aktivitasnya berorientasi pada kekhusukannya kepada Allah.

            Inilah memang tuntutan relevansi uzlah dalam tatanan dunia modern, dimana benturan zaman dan peradaban menjadikan seseorang dapat tergoyahkan jika terlena, namun malah sebaliknya jika benturan itu dapat diatasi dengan baik malah menjadi contoh dan konsep yang dapat terintegrasikan dengan baik. Layaknya seperti air dan minyak yang tidak pernah menyatu, tetapi dapat bergandengan, maka seseorang dalam hal ini harus dapat menggandeng peradaban dan nilai uzlah sebagai ajaran spritual Islam.
ISLAM DAN KRITISASI KEBERADAAN PANCASILA DALAM PEMBENTUKAN PERATURAN PERUNDANG-UNDANGAN
Authors: Adri Adri Yanto
Published: August 2023

Pancasila merupakan salah satu media pemersatu dalam  kehidupan bernegara di Indonesia. Dalam konteks hukum, khususnya dalam pembentukan peraturan perundang-undangan, Pancasila semestinya diletakkan dalam wilayah sumber hukum materil dari pembentukkan peraturan undang-undang. Di sisi lain, dalam perkembangan hukum nasional masih ditemui undang-undang yang tidak sesuai dengan nilai-nilai Pancasila. Terjadinya ketidakpastian, disharmonisasi dan dikotomi dalam regulasi terhadap nilai-nilai Pancasila yang akan berimplikasi terhadap implementasinya. Maka diperlukan penambahan pasal atau pencantuman Pancasila secara rinci dan jelas sebagai hierarki tertinggi dalam undang-undang pembentukan peraturan perundang-undangan. Memang secara dasar antara Pancasila dengan Al-Quran tidak bisa disamakan karena berbeda sumber. Akan tetapi dalam Siyāsah dustūriyyah memegang prinsip keadilan, persamaan, toleransi, hak asasi manusia dan musyawarah sehingga memiliki korelasi dan relevansi yang erat dengan sistem pembentukan peraturan di Indonesia. Dengan demikian, setiap hal dalam konteks penyelenggaraan negara, peraturan perundang-undangan, pemerintahan, sistem demokrasi dan lainya harus selaras dan terintegrasi dengan nilai-nilai Pancasila.

Authors: Ibrahim Suror Khalil , Hassan Abdullah Athbi
Published: August 2023

Background: Cerebrovascular accident (stroke) frequently results in problems with balance, which increase the risk of falling. Patients with stroke might improve their balance skills and reduce the occurrence of falls by engaging in sitting balance training exercises.     
Objectives: The current study aims to examine the effect of sitting balance exercises on the risk of fall in patients with stroke.    
Methodology: A quasi-experimental design was performed on sixty patients with acute stroke by using a purposive sampling method. The recruited patients were divided to experimental and control groups with 30 patients each. Patients in the experimental group were followed to perform sitting balance exercises two sessions per day for 14th days, whereas the patients enrolled in the control group received a routine conventional care.        
Results: More than half of patients participating in the experimental group were within the age groups of 60-69 years old and accounted for 53.3%, 56.7% of the experimental group were female while 46.7% of the control group were males. Before applying sitting balance exercises, the experimental group's overall mean score for the level of falling incidences risk level was 1.2±0.40 and 2.1 ±0.86 after implementing the intervention. There is a significant statistical difference in the level of falling risk between the two groups after implementing the interventional protocol at a P<0.001.
Conclusion: Performing of sitting balance exercises immediately after diagnosis with stroke was significantly improved stetting balance and decreased the incidence of falling in patients with stroke

Published: August 2023

Sepsis, caused by various bacterial pathogens, is a significant contributor to maternal mortality worldwide. In many developing countries, including Ethiopia, empirical or syndromic treatment is commonly employed for puerperal sepsis, which may promote antimicrobial resistance (AMR). We conducted a cross-sectional study to investigate bacterial pathogens, their antimicrobial susceptibility patterns, and associated factors among women with suspected puerperal sepsis attending Asella Referral and Teaching Hospital from September 2020 to August 2021. A total of 174 participants were enrolled, and the sociodemographic and obstetric data were collected using a pretested structured questionnaire and checklist, respectively. Blood samples (approximately 20 ml) were collected from all study participants and incubated in BacT/ALERT® 3D automated blood culture system. In addition, endocervical swabs were collected in Amies transport media. Bacterial isolation and identification were performed following standard bacteriological methods. Antimicrobial susceptibility profiles of bacterial isolates were determined using the disc diffusion method. Data were entered into EpiData version 4.6 and analyzed using SPSS version 25.0. The overall positivity rate of bacterial isolates among puerperal sepsis-suspected women was 48.9%. Among these, 87.1% of the isolates were Gram-negative bacteria. The most common isolates were Escherichia coli (54.1%), followed by Klebsiella spp. (23.5%) and Staphylococci aureus (10.6%). High resistance rates were observed in E. coli to piperacillin (87%), in Klebsiella spp. to aztreonam (65%) and ceftriaxone (65%), and in S. aureus to trimethoprim-sulfamethoxazole (66.6%). Multidrug-resistant bacterial pathogens accounted for 81.2% of the isolates in this study. Multivariate regression analysis did not reveal any statistically significant association between the presence of bacteria and the sociodemographic and obstetrics factors. Our findings emphasize the urgency of strengthening microbiology services to optimize patient management and combat AMR in puerperal sepsis.
Inhibitory Potential of Chitosan Derivatives against Severe Acute Respiratory Syndrome Coronavirus 2: An In Silico Prospective
Authors: Das Poonam , Sahoo Sabuj , Majhi Sanatan , Kerry Rout George , Singh Anup Kumar , Jena Atala Bihari
Published: August 2023

The present work was designed to investigate the antiviral potential of novel monomeric and oligomeric chitosan derivatives through in silico approaches. The goal was to identify potent broad-spectrum antiviral compounds as promising drug candidates against severe acute respiratory syndrome coronavirus 2 and understand their mode of action. Chitosan biopolymer and its derivatives were virtually screened against the spike glycoprotein and human angiotensin-converting enzyme 2 (ACE2) receptor of novel coronavirus-19. Hydroxypropyl trimethyl ammonium chloride chitosan (HTCC), a polymeric chitosan, has been reported to interact with the corona viral spike (S) protein and blocks its interaction with the ACE2 receptor. The enhancement of antiviral activity relies on better biocompatibility, structural correlations, variation in the degree of deacetylation, and molecular weight of modified chitosan derivatives. The chitosan derivatives constructively interact with viral S protein. Among the chitosan derivatives, N-carboxymethyl chitosan (NCMC) displayed efficient binding affinity. Comparing NCMC to mHTCC, monomeric chitosan, for their interaction with the S protein, receptor binding domain site, and ACE2 receptor, NCMC displayed better binding affinity of −7.9, −6.3, and −7.4 with binding energies of −6.2, −4.8, and −5.5 kcal/mol, respectively. Furthermore, through flexible docking, the interactions of the S protein with ACE2 receptor and ligand mHTCC-S protein complex and NCMC-S protein complex with ACE2 receptor were calculated, showing an efficient reduction of binding energy from −901.2 kJ/mol to −765.06 kJ/mol and −814.72 kJ/mol, respectively. This points to the decrease binding affinity of the viral S protein for the ACE2 receptor in the presence of NCMC/mHTCC. For the first time, the computational study envisages the antiviral efficiency of NCMC, mHTCC, and biocompatible chitosan derivatives as a preventive intervention against COVID-19.
Being a Non-Swedish Physician in Sweden: A Comparison of the Views on Work Related Communication of Non-Swedish Physicians and Swedish Health Care Personnel
Authors: Berbyuk Nataliya , Allwood Jens , Edebäck  Charlotte
Published: August 2023

Sweden is rapidly changing from being a monocultural to a multicultural society. The effects of this process can also be seen in health care which has, up till now, been one of the most ethnically and gender segregated working places, compared to the industrial sector. Increasing multiculturality places the issue of intercultural communication on top of the agenda for Swedish society in general and for the health care sector in particular.
This article is based on the results of two interrelated questionnaires, one directed at non-Swedish physicians, a relatively new but rapidly growing group in Swedish heath care, and one directed at Swedish health care personnel, a traditionally ethnically homogeneous group. The respondents’ answers have been summarised and compared in order to get a comprehensive picture of intercultural communication in Swedish health care.
Conscius recognition of the limitations of human knowledge as the foundation of effective intercultural communication
Authors: Zhao Jingjing , Edmondson Nelson
Published: August 2023

In the ever-smaller contemporary world, intercultural communication plays an increasingly important role. This paper discusses how to set the contents of a relevant package of university courses, which, while giving appropriate attention to practical solutions of intercultural communication problems, at the same time strongly emphasizes the final limitations of all human philosophical, religious, ideological, and even scientific comprehension. The paper proposes an educational strategy for dealing constructively with these limitations through raising the consciousness of their nature especially on the part of persons in positions of authority in different cultures. This should produce a greater sense of cultural modesty on the part of those persons, and therewith a reduction in intercultural conflicts. With this goal in mind, the paper proposes that such limitations be made the common platform of intercultural communication, thereby enriching this field of study.

As a background I present a model of resilience developed from a review of a number of studies as well as my own research. This model shows how the various protective factors can be divided into three main groups, and how different combinations of these factors develop resilience through some basic psychological processes. Based on a dynamic definition of culture, the article presents examples of three different cultures and how they generate resilience.The article then briefly discusses four issues in relation to resilience and culture:1. Protective factors – universal or contextual,2. Different ways of creating resilience,3. Resilience and vulnerability from culture,4. Minority and majority cultures, biculturalism and resilience.In the discussion the article make comparisons between Southern African culture and Norwegian culture. Lastly, the article highlights some possible educational implications of the study.
Politeness in Intercultural Email Communication: Australian and Korean Perspectives
Authors: Murphy Margaret , Levy Mike
Published: August 2023

This paper presents initial results from analysis of data collected on the topic of politeness in intercultural email communication from a large cohort of Australian academic and general staff at an established metropolitan university. We were interested in the language used by these staff members while they conducted their initial email communication with their contacts overseas. The contacts overseas were, for example, fellow professional colleagues, representatives from educational institutions and foreign students. The staff members did not know personally their overseas email partners in the sense that they had not previously met face-to-face. In particular, we were interested in if and how the staff members incorporated politeness indicators in their email language and how they interpreted politeness, or lack thereof, in their incoming emails. The paper also describes and analyses the politeness strategies in intercultural emails used by a smaller cohort of Korean academics at seven universities in Korea. Results show differences in politeness, both in expectations and use, between Australian and Korean academics.
Themes and conceptual developments were identified in the primary data-gathering instrument, the questionnaire, using qualitative data analysis. The software package Leximancer was used for text analysis (Smith 2002). The software analysis confirms and strengthens our own qualitative analysis. Results show aspects such as formality in language and use of correct titles are important politeness considerations in intercultural email communication. These politeness considerations however, vary according to culture and results show many discrepancies on these and other aspects between the Australian and Korean data. Figures showing ranked themes display these results visually.
Cultural Fluency as a Guide to Effective Intercultural Communication: The Case of Japan and the U.S.
Authors: Inoue Yukiko
Published: August 2023

Intercultural communication serves a vital role in that it can forestall miscommunication and misunderstanding. Because of increased intercultural contact and interdependence, people in the world are forced to "rethink" intercultural communication in order to acquire effective intercultural communication competence. The present paper provides a critical discussion of the conceptualization of intercultural communication and the commonly acknowledged challenge of intercultural communication. With a focus on Japan and the U.S. (since both countries have remarkably different forms of communication in terms of nonverbal communication particularly), the paper defines culture and explores the following: (1) origin of intercultural communication research; (2) cultural fluency and willingness to communicate; and (3) words versus haragei (a Japanese concept), touching upon intercultural (business) communication.

Published: August 2023

ccording to a study conducted in 2014 by Pusat Penyelidikan Wanita dan Jantina (KANITA) at Universiti Sains Malaysia (USM), 9% of women who have ever had a partner in Peninsular Malaysia had domestic violence at one compilation in their lives. In 2010, there were 3,173 cases of domestic violence reported. However, this number increased to 5,014 cases in 2015. According to the Corporate Communication division of Kementerian Pembangunan Wanita, Keluarga dan Masyarakat, calls to Talian Kasih have increased by 57 percent since Perintah Kawalan Pergerakan (PKP).  However, calls and WhatsApp messages to the Women’s Aid Organization (WAO) helpline were reduced to 73% of calls a week during the PKP.  Before PKP were enforced, WAO received an average of 77.5% of calls and message via WhatsApp in a week. This reduction does not mean that there is a reduction in cases because it is feared that the victim will not be able to make calls due to the situation where they are always with the abuser during the period of PKP. This study aims to develop a mobile application to aid and guide people facing domestic violence. The primary function of this application is to help the victim; 1) to record their evidence in audio/video recording, 2) to help the victim to alert the polis in case of emergency, 3) to get help and find the nearest shelter whenever needed. This mobile application is developed using the Flutter framework. Firebase is used as the back-end component to store all the records. The result of this study is the improvement of the existing mobile application for domestic violence in Malaysia.

The Sustainable Development Goals (SDGs) are in trouble half-way towards their target date of 2030. With increasing global inequalities, and reversal in developmental gains because of the COVID-19 pandemic, as well as financial and political instability, achieving the goals in the next seven years seems difficult. We undertake an exercise in defining an ecological system of the SDGs to argue that focusing on two sentinel goals of SDGs 5 & 12 (‘gender equality’ and ‘responsible consumption and production’) could be key to achieving the other goals. The linkages posited in the SDG ecosystem are based upon our reading of the literature from a political economic and political ecological perspective. Prioritising SDGs 5 and 12 requires more of political rather than a financial commitment. The paper proposes a pathway to achieving some success in realising SDGs during their remaining half-life.

The theory of dynamical systems of conflict in the framework of functional analysis
Authors: Koshmanenko Volodymyr
Published: August 2023

In this article, we give an introduction to the mathematical setting of problems related to the phenomenon of conflict in terms of constructions in Hilbert spaces. The struggle (conflict, game) between opponents (adversaries, players) will be represented by operator transformations of vectors in Hilbert spaces and probabilistic distributions on the territory of life resources. The phenomenon of conflict as a contradiction between opponents appears in mathematical terms as an intersection the domains of definition for operators and overlapping of corresponding measures. Conflict interaction between opponents in the physical sense is described by the specific transformation of states in a Hilbert space. In turn, this is a mapping that changes the spectral measurements. Thus, a complex dynamical system arises, which we call a dynamical system of conflict. Then the following main problems arise as fundamental questions. What reasonable law of engagement (game or war) should be adopted to resolve the initial intersections? What is a fair limiting distribution of the resource territory? In a more general formulation, solving conflict problems means the detailed describing of all possible outcomes on opponents states of the type: victories, defeats, states of equilibrium, compromises as fixed points together with their basins of attraction.
DIFFERENT TYPES OF INTUITION AT THE WORKPLACE: AN INTEGRATIVE REVIEW

To make good decisions, employees must manage their own intuitions and be able to anticipate decision-making in their work environment. How well this is accomplished has significant consequences for the workplace. A closer examination indicates that individuals utilize various types of intuition. People’s work context is frequently omitted from studies on the use of intuition, resulting in a literature that omits vital aspects of decision-making. To assist applicable research in the workplace, our contribution to the management literature is a comprehensive overview of intuitive decision-making types. Current psychological assessment scales constitute a mature discipline, but they frequently lack the professional applications needed in business administration and economics. Considering this, the primary objective of this article is to assemble and assess many types of intuition and combine them into a new lens for research in the theory and practice of business using a multidimensional approach. It is comprised of rational choice theory, classical intuitive decision making, emotional decisions (gut feelings), fast heuristic decisions, unconscious thought, and anticipation. The overview of several scientifically proven measuring scales produces a theoretical foundation for future empirical study in business administration and economics based on these findings.

We present the results of ALMA-ACA 7 m array observations in 12CO(J = 2–1), 13CO(J = 2–1), and C18O(J = 2–1) line emission toward the molecular-gas disk in the Local Group spiral galaxy M33 at an angular resolution of 7.″31 × 6.″50 (30 × 26 pc). We combined the ACA 7 m array 12CO(J = 2–1) data with the IRAM 30 m data to compensate for emission from diffuse molecular-gas components. The ACA+IRAM combined 12CO(J = 2–1) map clearly depicts the cloud-scale molecular-gas structure over the M33 disk. Based on the ACA+IRAM 12CO(J = 2–1) cube data, we cataloged 848 molecular clouds with a mass range from 103–106
M
⊙. We found that high-mass clouds (≥105
M
⊙) tend to associate with the 8 μm bright sources in the spiral arm region, while low-mass clouds (<105
M
⊙) tend to be apart from such 8 μm bright sources and to exist in the inter-arm region. We compared the cataloged clouds with GMCs observed by the IRAM 30 m telescope at 49 pc resolution (IRAM GMC), and found that a small IRAM GMC is likely to be identified as a single molecular cloud even in ACA+IRAM CO data, while a large IRAM GMC can be resolved into multiple ACA+IRAM clouds. The velocity dispersion of a large IRAM GMC is mainly dominated by the line-of-sight velocity difference between small clouds inside the GMC rather than the internal cloud velocity broadening.

We present the results of an unbiased 12CO/13CO/C18O (J = 1–0) survey in a portion of the third Galactic quadrant (TGQ): 219.°75 ≤ l ≤ 229.°75 and −5.°25 ≤ b ≤ 5.°25. The high-resolution and high-sensitivity data sets help to unravel the distributions and physical properties of the molecular clouds (MCs) in the mapped area. In the LSR velocity range from ∼−1 to ∼85 km s−1, the molecular material successfully traces the Local, Perseus, and Outer arms. In the TGQ, the Outer arm appears to be more prominent than that in the second Galactic quadrant (SGQ), but the Perseus arm is not as conspicuous as that in the SGQ. A total of 1,502 12CO, 570 13CO, and 53 C18O molecular structures are identified, spanning over ∼2 and ∼6 orders of magnitude in size and mass, respectively. Tight mass–radius correlations and virial parameter–mass anticorrelations are observable. Yet, it seems that no clear correlations between velocity dispersion and effective radius can be found over the full dynamic range. The vertical distribution of the MCs renders evident pictures of the Galactic warp and flare.

We present five far- and near-ultraviolet spectra of the Type II plateau supernova, SN 2022acko, obtained 5, 6, 7, 19, and 21 days after explosion, all observed with the Hubble Space Telescope/Space Telescope Imaging Spectrograph. The first three epochs are earlier than any Type II plateau supernova has been observed in the far-ultraviolet revealing unprecedented characteristics. These three spectra are dominated by strong lines, primarily from metals, which contrasts with the featureless early optical spectra. The flux decreases over the initial time series as the ejecta cool and line blanketing takes effect. We model this unique data set with the non–local thermodynamic equilibrium radiation transport code CMFGEN, finding a good match to the explosion of a low-mass red supergiant with energy E
kin = 6 × 1050 erg. With these models we identify, for the first time, the ions that dominate the early ultraviolet spectra. We present optical photometry and spectroscopy, showing that SN 2022acko has a peak absolute magnitude of V = − 15.4 mag and plateau length of ∼115 days. The spectra closely resemble those of SN 2005cs and SN 2012A. Using the combined optical and ultraviolet spectra, we report the fraction of flux as a function of bluest wavelength on days 5, 7, and 19. We create a spectral time-series of Type II supernovae in the ultraviolet, demonstrating the rapid decline of flux over the first few weeks of evolution. Future observations of Type II supernovae are required to map out the landscape of exploding red supergiants, with and without circumstellar material, which is best revealed in high-quality ultraviolet spectra.
