Extinction behavior and recurrence of n-type Markov branching–immigration processes
Authors: Li Junping , Wang Juan 
Published: January 2024

AbstractIn this paper, we consider n-type Markov branching–immigration processes. The uniqueness criterion is first established. Then, we construct a related system of differential equations based on the branching property. Furthermore, the explicit expression of extinction probability and the mean extinction time are successfully obtained in the absorbing case by using the unique solution of the related system of differential equations and Kolmogorov forward equations. Finally, the recurrence and ergodicity criteria are given if the zero state 0 is not absorbing.
Challenges of the green transition for the recovery of the Western Balkans
Authors: Ignjatović Jelena , Filipović Sanja , Radovanović Mirjana 
Published: January 2024

Abstract
Background
The aim of this paper is to reconsider the necessity for the green transition and the key preconditions for the implementation of a circular economy in Western Balkan countries. With the objective of the research in mind, the method of analysis and synthesis was applied to determine (1) regulatory and institutional prerequisites for the green transition; (2) the need for the Western Balkan countries to redefine the model of sustainable economic growth towards the green transition; (3) the development opportunities for recovery defined in the Green Agenda for the Western Balkans; and (4) the possibility of implementing the circular economy in the Western Balkans.

Main text
The main findings of the research indicate that: (1) the countries of the Western Balkan region, following the example of the EU, should define a national strategic approach to the green transition with an accompanying action plan and regulatory framework; (2) the biggest challenge of the green transition is the reform of the energy sector and the restructuring of the energy-intensive economy; (3) the countries have untapped potential in renewable energy sources and report the improvement of energy efficiency; (4) the circular economy can boost the green transition, because the countries of the region have a five-time lower value of resource productivity than the average of the EU, while the generation of waste (excluding major mineral wastes) per GDP unit is lower compared to the EU; (5) cross-sectoral governance should be more coordinated.

Conclusions
The green transition might be a development opportunity for the Western Balkans, which should enable sustainable economic growth as well as energy security and environmental protection. However, the implementation of the Green Agenda is not easy, because the region faces the problem of underdeveloped regulatory and institutional capacities that might provide not only the base for long-term planning but also financial resources for the efficient implementation of projects. In addition, it is essential to understand the principles of the Green Agenda and the interaction of all activities that should enable the achievement of defined goals.
“Waste to energy” as a driver towards a sustainable and circular energy future for the Balkan countries
Authors: Bjelić Draženko , Markić Dragana Nešković , Prokić Dunja , Malinović Borislav N. , Panić Andrea Andrejević 
Published: January 2024

Abstract
Background
The main goal of the paper is to review the existing state and propose a model solution for the introduction of the waste-to-energy concept in the Republic of Serbia and Bosnia and Herzegovina, as these Balkan countries are a source of high pollution due to the inefficient use of fossil fuels and the operation of coal-fired power plants. Besides, these countries have very low level of waste management, which results in the uncontrolled disposal of a large amount of waste which consists of plastic and microplastic materials which are difficult to decompose in natural ecosystems.

Methods
Considering the type and objectives of the study, a mixed research method was chosen as a combination of exploratory research, descriptive research, explanatory research, and modeling.

Results
The main result of the research shows the unfavorable situation in the field of waste management in the Republic of Serbia, as well as in Bosnia and Herzegovina. Both countries have adopted adequate strategies and plans, but waste management is not implemented accordingly, Nevertheless, numerous problems create considerable opportunities for improvement, especially regarding the potential for energy production from waste, which is an important approach to implementing the circular economy model. The study showed that the situation is particularly unfavorable in rural areas. Hence, the research proposes (a) a novel model for waste-to-energy governance and (b) a novel model for waste-to-energy management in rural areas. The research was done, and models were developed based on the examples of the Republic of Serbia, and Bosnia and Herzegovina. However, the results can be used in countries with a similar level of waste management and with a larger share of rural areas.

Conclusions
The paper emphasizes the importance of a holistic and systemic approach to waste management, with emphasis on using waste-to-energy concept as particularly applicable in the transition to circular economy. This study proposes a model for the integration of waste management (with emphasis on plastic and microplastic) and energy efficiency, presenting a model of approach that can be used in countries that are at the beginning of introducing a circular economy.

Published: January 2024

Abstract
Background
A high workload may negatively impact the surgical team's performance and jeopardize patient safety. The aim of this study was to measure the workload of the surgical team across different surgical roles, specialties, and techniques in several hospitals.

Methods
This cross-sectional multicenter study was performed in the operating rooms of eight teaching hospitals affiliated with Isfahan University of Medical Sciences, Iran. At the conclusion of each surgical procedure, all members of the surgical team completed the Surgery Task Load Index (SURG-TLX) questionnaire to assess workload levels. Descriptive statistics, analysis of variance (ANOVA), and Pearson correlations, were performed to compare surgical roles, specialties, techniques, and surgical time on workload overall and by subscale.

Results
A total of 409 workload questionnaires were obtained from 76 surgical teams or cases, involving 346 surgical team members. The total workload among all participants was 32.41 ± 17.21. Surgical complexity, physical demands, and mental demands were the highest workload subscales and distraction was the lowest workload subscale. Cardiovascular specialty had a higher workload compared to other specialties. Open techniques resulted in a higher workload compared to minimally invasive techniques. Surgical technologists who act in both the role of circulating and scrub nurse (C&Ss) experienced the highest workload, followed by surgical residents and surgeons.

Conclusions
The results of the study showed that the workload for some members of the surgical team is disproportionately high and is influenced by factors such as specialty, technique, role, and surgical duration. By knowing the distribution of workload among the members of the surgical team, efforts can be made to optimize the team members’ workload.
How staying in a gymnasium affects sleep and bed climate in children
Authors: Okamoto-Mizuno Kazue , Mizuno Koh 
Published: January 2024

Abstract
Background
We investigated the relationship between sleep, ambient climate, and bed climate in school-aged children during a one-night stay in a simulated shelter in a gymnasium to demonstrate the effect of ambient climate, and bed climate on sleep.

Methods
We obtained measurements during a one-night stay in a school gymnasium (C), days before C (BC), on the day after (A1), and on the second day after C (A2) in 13 healthy school-aged children during summer. Sleep was evaluated using an actigraph, and the temperature and humidity of the bedrooms in the participants’ homes and in the gymnasium were monitored for 3 days before and after C. The bed climate of the chest and foot areas was measured for two nights before and after C. The participants were asked to report on their subjective sleep estimations and thermal sensations two nights before and after C.

Results
The ambient temperature in C was significantly higher than that in BC at the initial 180 min, while it significantly decreased compared to A1 and A2 in the last 100 min. The ambient humidity was significantly higher in both C and BC compared to A1 and A2. The sleep efficiency index decreased significantly in C (43±4.8%) compared to other conditions. Sleep time was significantly shorter in C than in other conditions during the initial 195 min. The increase in the bed climate temperature of the chest area in C was significantly delayed compared to that in the other conditions, around the initial 30 min after the lights were off. Subjective estimation revealed that in C, 85% of the participants were out of their sleeping bag at sleep onset, and their sleep was disturbed by heat (77%).

Conclusions
Our study revealed that the disturbed sleep patterns observed with children in a simulated shelter may be related to a delayed increase in bed climate temperature in the chest area. This delayed increase could be related to the children not entering the sleeping bag and a delayed chest skin temperature increase during the sleep onset period.
Alleviation of acute stress response by black pepper aroma administration
Authors: Dilrukshi E. A. Chayani , Nishiyama Yuta , Ito Kanetoshi , Nomura Shusaku 
Published: January 2024

Abstract
Background
Black pepper is one of the most popular spices globally. As black pepper essential oil has not yet been used in the context of aromatherapy, this study examined the effect of black pepper aroma on cardiac and peripheral autonomic nervous system (ANS) activity under stressful conditions using an olfactometer to administer aroma in a precise and controlled manner to ensure reproducibility.

Methods
A within-participant design experiment was conducted with 20 male university students who performed a 30-min calculation task as a short-term stressor under three aroma conditions: black pepper, ginger, and dipropylene glycol (DPG) (scentless air as a control). Each aroma was sporadically delivered (first 20 s of each 1-min interval) with the olfactometer during the task. Electrocardiograms and skin conductance level (SCL) were measured to evaluate ANS's physiological acute stress response. Subjective evaluations for the given stressful task and impressions on the types of aromas were assessed.

Results
The physiological acute stress response induced by the short-term stressor, which is characterized by the enhancement of the heart rate (HR) and SCL and decreases in the heart rate variability (HRV), was suppressed with black pepper: the increase in HR and reduction in HRV from the baseline were 38.9% (p = 0.048 when compared with DPG) and 32.9% smaller (p = 0.002 for multiple comparisons) than those in DPG, respectively, and the increase of SCL was 15.5% smaller (p = 0.005 for multiple comparisons) than that in ginger. However, there was no significant difference in subjective scores among the conditions.

Conclusion
Although black pepper is a stimulative agent, the study findings showed that black pepper aroma alleviated the physiological acute stress response, which can be beneficial in aromatherapy under stressful conditions.
Impact of an oligosaccharide-based polymer on the metabolic profiles and microbial ecology of weanling pigs experimentally infected with a pathogenic E. coli
Authors: Kim Kwangwook , Jinno Cynthia , Li Xunde , Bravo David , Cox Eric , Ji Peng , Liu Yanhong 
Published: January 2024

Abstract
Background
Our previous study has reported that supplementation of oligosaccharide-based polymer enhances gut health and disease resistance of pigs infected with enterotoxigenic E. coli (ETEC) F18 in a manner similar to carbadox. The objective of this study was to investigate the impacts of oligosaccharide-based polymer or antibiotic on the host metabolic profiles and colon microbiota of weaned pigs experimentally infected with ETEC F18.

Results
Multivariate analysis highlighted the differences in the metabolic profiles of serum and colon digesta which were predominantly found between pigs supplemented with oligosaccharide-based polymer and antibiotic. The relative abundance of metabolic markers of immune responses and nutrient metabolisms, such as amino acids and carbohydrates, were significantly differentiated between the oligosaccharide-based polymer and antibiotic groups (q < 0.2 and fold change > 2.0). In addition, pigs in antibiotic had a reduced (P < 0.05) relative abundance of Lachnospiraceae and Lactobacillaceae, whereas had greater (P < 0.05) Clostridiaceae and Streptococcaceae in the colon digesta on d 11 post-inoculation (PI) compared with d 5 PI.

Conclusions
The impact of oligosaccharide-based polymer on the metabolic and microbial profiles of pigs is not fully understood, and further exploration is needed. However, current research suggest that various mechanisms are involved in the enhanced disease resistance and performance in ETEC-challenged pigs by supplementing this polymer.

Mental health disparities in young adults with arrest history: a survey-based, cross-sectional analysis
Authors: Baser Onur , Rodchenko Katarzyna , Zeng Yixuan , Endrizal Amy 
Published: January 2024

Abstract
Background
Over 4.53 million arrests were made in 2021 in the United States. People under 26 years of age were more likely to be arrested than older people. Although mental health disparities are prominent in the incarcerated population, the subject has not been closely examined among young adults specifically.

Objectives
This study examines how criminal justice involvement, specifically arrests, affects the mental health of adults between 18 and 25 years of age.

Methods
We analyzed secondary data using the 2021 National Survey on Drug Use and Health (NSDUH). The study used a subsample of 13,494 people aged 18 to 25 years, including 7,330 women and 6,164 men. History of arrest was the key independent variable. Depression, serious mental illness (SMI), substance use, suicidal ideation, and suicide attempt were the outcome variables. We performed five multivariate logistic regression models for each outcome variable, controlling for race/ethnicity, income, and education level for men and women separately.

Results
Of 13,494 respondents, 6.63% had a history of arrest. Among young women, a history of arrest was associated with significantly higher adjusted odds ratios for all mental health concerns. Most notably, a history of arrest increased the likelihood of substance use by a factor of 15.19, suicide attempts by 2.27, SMI by 1.79, suicidal ideation by 1.75, and depression by 1.52. Among young men, a history of arrest was associated with increased adjusted odds ratios (AORs) for substance use (AOR, 13.37; p < .001), suicidal ideation (AOR, 1.45; p = .011), and suicide attempt (AOR, 1.82; p = .044).

Conclusions
We found a strong relationship between young people having an arrest history and mental health concerns. More specifically, a history of arrest was associated with all mental health concerns among young women, while it was associated with only substance use and suicide among young men. Providing arrestees with appropriate mental health care would benefit them and the criminal justice system by decreasing the odds of recidivism.
Time perspectives and procrastination in university students: exploring the moderating role of basic psychological need satisfaction
Authors: Codina Nuria , Castillo Isabel , Pestana José Vicente , Valenzuela Rafael 
Published: January 2024

Abstract
Background
Research on procrastination, regarding time perspective factors and basic psychological need satisfaction (BPNS) has placed this problem at the meeting point of individual and contextual variables. The present study focused both on the individual, given that time perspectives can be defined as a person’s attitude to an object (time) at three moments (present, past, future); and on contextual aspects, because the satisfaction of basic psychological needs (competence, autonomy, relatedness) is facilitated or made difficult by social contexts. Based on this, the aim of this study was to analyse the relationships between time perspectives and inter-subject procrastination variations, testing the moderating role of BPNS in this relationship.

Method
A total of 1,188 undergraduate students, aged 17–50 years (M = 20.02, SD = 2.63), completed three questionnaires containing the variables of interest.

Results
Regression analyses showed significant negative (thus, potentially protective) association of future time perspective with all three procrastination dimensions (decisional procrastination, implemental delay, and lateness). Conversely, past-negative time perspective showed a positive (thus, potentially adverse) association with procrastination. Satisfaction of the need for competence also showed a negative (thus, potentially protective) association with all procrastination dimensions. On eight occasions, the relationships between time perspectives and procrastination dimensions were moderated by psychological need satisfaction.

Conclusions
These findings show that BPNS may play relevant roles in the negative (favourable) relationships between procrastination dimensions and positive time perspectives, as well as in the positive (adverse) associations between negative time perspectives and procrastination dimensions. Contextual interventions fostering enhanced levels of perceived autonomy, competence, and relatedness, as well as future time perspective, are thus strong candidates to consider for use and evaluation by policy makers, pedagogues, teachers, coaches and other professionals interested in counteracting procrastination tendencies.
Wow, I cannot stop: a concentration on vocabulary learning via instagram and its effects on informal digital learning of english, technostress, and on-line engagement
Authors: Almohesh Ali Rashed Ibraheam , Altamimi Jinan Abdulaziz Hamad 
Published: January 2024

AbstractThe proliferation of social media in contemporary society presents a compelling impetus for scholars to explore the untapped capabilities of social networking platforms with the aim of enhancing educational practices. Despite the notable impact of social media on the acquisition of second or foreign languages, there is a scarcity of empirical research investigating the influence of Instagram feed-based activities on the development of vocabulary in language learning at under-intermediate level. In order to address this research gap, the present study aimed to investigate the impact of Instagram feed-based activities on the acquisition of vocabulary among individuals studying English as a foreign language (EFL). As a result, a cohort of 79 intermediate EFL learners was subjected to random assignment, leading to the formation of both experimental and control groups. The participants in the control group were provided with conventional online teaching using webinar platforms. The participants in the experimental group, on the other hand, were instructed via the use of webinar platforms and were required to participate in exercises that were based on Instagram feeds respectively. The results of the data analysis using one-way Multivariate Analysis of Variance (MANOVA) revealed that the learners in the experimental group (EG) demonstrated superior performance compared to their counterparts in the control group (CG). The findings underscored the notable impact of using Instagram feed-based activities in promoting the acquisition of vocabulary knowledge. Additionally, it was shown that EFL learners had favorable views towards the use of Instagram Feed-based Tasks for the purpose of learning vocabulary. Due to treatment, EG achieved higher state in informal digital learning of English and on-line engagement. Moreover, they felt less technostress after treatment. The findings of this research have potential consequences for language learners, instructors, curriculum designers, and policy makers. Specifically, they suggest that incorporating Instagram feed-based activities into language learning and teaching may provide valuable chances for further practice.
