En el siglo XIX se utilizaron los distintos géneros que dieron soporte al periodismo. Hasta la llegada de Porfirio Díaz al gobierno de México, los géneros de opinión fueron los que se emplearon principalmente en la prensa, y es entendible tal uso, dado que con ellos se consideraba que la prensa periódica iba delineando los derroteros políticos del país, ya fuera desde una perspectiva conservadora, o bien desde un planteamiento liberal. Así, el artículo, el editorial, la crónica, muchas veces con una estructura literaria, y el boletín (nombre que recibía una pieza textual, similar a lo que es la columna actual, en la que el periodista emitía sus opiniones, que se ubicaba en el mismo lugar dentro del periódico, con título fijo, y que fue empleada durante casi todo el siglo XIX), se usaron con asiduidad y más, frecuentemente, en los momentos de mayor violencia política, sobre todo desde el surgimiento del México independiente y hasta 1876, cuando comenzó una nueva forma de gobierno.
Escritores mexicanos en periódicos españoles: estrategia de opinión y contratación de trabajo intelectual (periodo electoral de 1884)
Authors:   Universidad Nacional Nacional México, Instituto de Investigaciones Bibliográficas, Mexico, Vieyra Sánchez Lilia
Published: August 2022

La presente investigación analiza en qué medida los dueños de periódicos españoles contrataron a escritores mexicanos para ejercer el género de opinión en torno a las disposiciones políticas que frenaban sus empresas y de esa manera evadir el artículo 33 (de censura a la actividad política de extranjeros). Además, ofrece elementos para sustentar que más allá de una estrategia para expresar su postura y defenderse, la contratación de mexicanos era un procedimiento útil para contar con los servicios de intelectuales asalariados que se ocuparan de elaborar una publicación, actividad que para los propietarios peninsulares de esos medios de comunicación era excesiva, ya que debían ocuparse de otros negocios que les demandaban mayor tiempo del que requería la actividad periodística. Aquí se pretende considerar que para los propietarios de periódicos españoles era factible contar con los servicios de escritores mexicanos, porque hablaban y escribían en la misma lengua, mientras que los directores de diarios alemanes, franceses y estadounidenses, que se publicaban en el idioma de esos grupos, debían contratar escritores que redactaran en esas lenguas. La demanda de un periódico escrito en un idioma diferente al español era menor, lo que se traducía en escasos suscriptores y pocos recursos para pagar el servicio de letrados mexicanos que hablaran alemán, francés o inglés, aunque lo más difícil era evitar que los cajistas y otros operarios de imprenta cometieran errores tipográficos por el desconocimiento de otros idiomas.
Mauricio Magdaleno y la memoria de Aguascalientes: entre la prensa periódica y la obra literaria
Authors:   Instituto Tecnológico Autónomo de México, Mexico, Arranz Mínguez Conrado J.
Published: August 2022

Además de que Mauricio Magdaleno emprende un proceso de rememoración de su infancia o juventud, en Aguascalientes y la Ciudad de México, lo hace al calor de la búsqueda de ese fuego que contiene la historia, en concreto, al de dos acontecimientos históricos cuyo cronotopo coincide con la infancia y juventud del autor: la Convención de Aguascalientes y la proclamación de José Vasconcelos como candidato a la Presidencia, además de la sucesiva campaña de la que Magdaleno tomó parte activa. No cabe duda de que en estos dos acontecimientos históricos se tuvo la oportunidad de dar un cambio de rumbo significativo al devenir histórico de la Revolución mexicana. En este trabajo nos limitaremos al análisis más pormenorizado del primero de ellos, dejando el segundo para un estudio posterior.

A pressuposição-defeito de Paul Henry e a pressuposição argumentativa de Oswald Ducrot
Authors: Machado Julio Cesar
Published: August 2022

Este artigo apresenta uma abordagem crítica a Paul Henry, em relação à sua contestação ao conceito de pressuposição de Oswald Ducrot, o que Henry fez com base em termos como “psicossocial”, “persuasão” e “influência”, termos esses estranhos à epistemologia ducrotiana. Nossa metodologia explora um melhor tratamento teórico constituinte da noção de pressuposição argumentativa, que, ao contrário do que apresentou Henry, nunca se opera isolada, mas é sempre operável em uma démarche argumentativa composta de pressuposto (pp), posto (p) e encadeamento (→). Conservando seus méritos, defendemos a hipótese de que Henry não desconstruiu porque não abordou a pressuposição argumentativa ducrotiana, mas trabalhou pontos de uma pressuposição-defeito mais limitada, que não resiste a ambiguidades e paradoxos, desconsiderando envergaduras e refinamentos da démarche argumentativa e suas cinco constitutividades, pelas quais a pressuposição ducrotiana insiste e resiste.

Highlights:1. There was a significant relationship between bone age calculated by the Tanner Whitehouse II method (TW2-20) and chronological age.2. There was a slowdown in bone age in pediatric patients at Universitas Airlangga Hospital (RSUA).
AbstractIntroduction: Bone age is an indicator of biological and skeletal maturity in individuals. It is different from chronological age which is calculated based on the time of birth. The differences in chronological age and bone age can indicate abnormalities in bone development. This study aimed to determine the profile of bone age in pediatric patients at Universitas Airlangga Hospital and the relationship between bone ages examined using the Tanner Whitehouse II (TW2-20) method and their chronological ages.Methods: This was a cross-sectional observational analytic study. Secondary data were collected from medical records and X-Ray examination results from Department of Radiology Universitas Airlangga Hospital (RSUA) Surabaya from January 2018 to December 2019. The data of age, gender, and history of illness were taken. From the collected X-ray results, bone age was examined using the TW2-20 method. Then, a normality test was performed using the Shapiro-Wilk for data less than 50 samples. The results showed that the data were normally distributed (p = 0.419). Data processing of the difference between bone age and chronological age was performed using the parametric paired T-test with a confidence level of 95%.Results: 32 samples were obtained from pediatric patients undergoing X-ray examinations from January 2018 to December 2019. The average bone age difference in male patients was 0.64 years old with the highest average difference found in the age range of 9-11.99 years old. The average bone age difference in female patients was 1.1 years old with the highest average difference found in the age range of 12-14.99 years old. There was a significant difference between bone age calculated using the TW2-20 method and chronological age (p < 0.001).Conclusion: Based on the comparison of the average bone age in pediatric patients and their chronological age, all samples showed deceleration of bone age in pediatric patients at RSUA. Based on the analytical study, the TW2-20 method was not suitable for the sample examined.

The gut-immune-brain axis in neurodevelopment and neurological disorders
Authors: Park John Chulhoon , Im Sin-Hyeog
Published: August 2022

The gut-brain axis is gaining momentum as an interdisciplinary field addressing how intestinal microbes influence the central nervous system (CNS). Studies using powerful tools, including germ-free, antibiotic-fed, and fecal microbiota transplanted mice, demonstrate how gut microbiota perturbations alter the fate of neurodevelopment. Probiotics are also becoming more recognized as potentially effective therapeutic agents in alleviating symptoms of neurological disorders. While gut microbes may directly communicate with the CNS through their effector molecules, including metabolites, their influence on neuroimmune populations, including newly discovered brain-resident T cells, underscore the host immunity as a potent mediator of the gut-brain axis. In this review, we examine the unique immune populations within the brain, the effects of the gut microbiota on the CNS, and the efficacy of specific probiotic strains to propose the novel concept of the gut-immune-brain axis.

A Direct Prediction of the Shape Parameter in the Collocation Method of Solving Poisson Equation
Authors: Luh Lin-Tian David
Published: August 2022

In this paper we totally discard the traditional trial-and-error algorithms of choosing acceptable shape parameter c in the multiquadrics $-\sqrt{c^{2}+\|x\|^{2}}$ when dealing with differential equations. Instead, we choose c directly by the MN-curve theory and hence avoid the time-consuming steps of solving a linear system required by each trial of the c value in the traditional methods. The quality of the c value thus obtained is supported by the newly born choice theory of the shape parameter. Experiments show that the approximation error of the approximate solution to the differential equation is very close to the best approximation error among all possible choices of c.

Considerable efforts have been made in recent years to identify an optimal treatment method for the removal of antibiotics from wastewaters. A series of supramolecular organic-inorganic magnetic composites containing Zn-modified MgAl LDHs and Cu-phthalocyanine as photosensitizer have been prepared with the scope to β-lactam antibiotics removal from aqueous solutions. The characterization of these materials confirmed the anchorage of Cu-phthalocyanine onto the edges of the LDH lamellae, with a negligible part inserted in the interlayer space. The removal of β-lactam antibiotics occurred via a concerted adsorption and photocatalytic degradation. The efficiency of the composites was depending on i) the LDH: magnetic nanoparticle (MP) ratio, that is strongly correlated to the textural properties of the catalysts, and ii) the phthalocyanine loading in the final composite. A maximum of the efficiency was achieved with a removal of ~93% of antibiotics after 2h of reaction.

Coronary artery disease (CAD) represents a modern pandemic associated with significant morbidity and mortality. The multi-faceted pathogenesis of this entity has long been investigated, highlighting the contribution of systemic factors such as hyperlipidemia and hypertension. Nevertheless, recent research has drawn light to the importance of geometrical features of coronary vasculature on the complexity and vulnerability of coronary atherosclerosis. Various parameters have been investigated so far, including vessel-length, cross-sectional area, curvature, and tortuosity, using primarily invasive angiography and recently non-invasive cardiac computed tomography angiography (CCTA). It is clear that there is correlation between geometrical parameters and both the haemodynamic alterations augmenting the atherosclerosis-prone environment and the extent of plaque burden. The purpose of this review is to discuss the currently available literature regarding this issue and propose a potential non-invasive imaging biomarker, the geometric risk score, which could be of importance to allow early detection of individuals at increased risk of developing CAD.

Published: August 2022

Globally, zoonotic diseases have been on the rise in recent years. Predictive modelling approaches have been successfully used in the literature to identify the underlying causes of these zoonotic diseases. We examine the latest research in the field of predictive modeling that verifies the growth of zoonotic pathogens and assesses the factors associated with their spread. The results of our survey indicate that popular mathematical models can successfully be used in modeling the growth rate of these pathogens under varying storage temperatures. Additionally, some of them are used for the assessment of the inactivation of these pathogens based on various conditions. Based on the results of our study, machine learning models and deep learning are commonly used to detect pathogens within food items and to predict the factors associated with the presence of the pathogens.

This article describes 8 guiding principles for the digital transformation of the health sector and identifies their relationship with the COVID-19 pandemic, as well as highlights their importance to countries undergoing digital transformation processes. In the Region of the Americas, among other gaps, 30% of people do not have access to the Internet, which is why it is mandatory to develop policies and actions to deliver public health interventions equitably and sustainably to ensure that no one is left behind. The 8 principles focus on the 4 areas of a sustainable health system—human, social, economic, and environmental—and highlight the broader possibilities for using digital technology to have an impact on the sustainability of health systems.

Contributions of the New Framework for Essential Public Health Functions to Addressing the COVID-19 Pandemic
Authors: Báscolo Ernesto , Houghton Natalia , Riego Amalia Del , Fitzgerald James , Jarboe Rachel
Published: August 2022

This article uses a health stewardship perspective to interpret the strengths of and challenges to national health authorities’ capacities to respond to the COVID-19 pandemic through the renewed essential public health functions (EPHF) framework. Based on a literature review, this article argues that the institutional capacities required by countries to respond to the COVID-19 pandemic in the Americas included all 4 stages of the new EPHF policy cycle: assessment, policy development, allocation of resources, and access. While health authorities provided these key functions (e.g., data analysis, intersectoral policy dialogues, allocation of additional funds), the interventions implemented depended on each country’s own institutional structures. Health authorities faced significant challenges including fragmentation and the lack of institutional and personnel capacities, thus compromising the delivery of an effective and equitable response. In addition, the response to the pandemic has been uneven because of weaknesses in central leadership and coordination capacity, the politicization of the response, and differences in the capacity to respond at subnational levels. Such challenges reflect structural weaknesses that existed before the onset of the pandemic, as well as the low prioritization of public health in agendas for health systems strengthening. A future agenda should prioritize improving structural elements while strengthening the stewardship capacities of health authorities and developing institutional structures that guarantee access to and universal coverage of health services.

Published: August 2022

The existence and content of water will certainly affect the effective pore space of shales and therefore is a key point for the evaluation of in-situ gas content and gas flow capacity of shale reservoirs. In order to reasonably evaluate the gas storage and flow capacities of water-bearing shale reservoirs, the effect of water on the effective pore space of shales needs to be understood. In this study, the Upper Permian Longtan shale in the southeastern Sichuan Basin, China, was selected as an example to conduct nuclear magnetic resonance cryoporometry (NMRC) measurements under different water saturation levels. The gas-accessible effective pore spaces in shales under different water saturation levels were quantified, and the effect of water saturation on gas-accessible effective pore space in shales was investigated. The results show that water plays an important role in the gas-accessible effective pore space of shales. When the Longtan shale increases from a dry state to a water saturation of 65%, 75%, and 90%, the gas-accessible effective pore volume decreases by 35%-60% (average 46.3%), 50%-70% (average 58.8%), and 65%-82% (average 75.8%), respectively. Water has an effect on the gas-accessible effective pore space regardless of pore size, and the effect is the strongest in the 4-100 nm range, which may be mainly due to the high content of clay minerals in the Longtan shale. Our studies are of important theoretical significance and application prospects for accurately evaluating the gas-accessible effective pore space of gas shales under actual geological conditions.
Is It Possible to Run at High Speed Rotation, Above 3600 RPM, Asynchronous Electrical Submersible System? Myth, or Reality
Authors: Escobar Carlos , Valencia Victor , Castro Jhon , León Carlos , Pérez Laura , Serrano Juan , Ariza Iván
Published: August 2022

Over the years, Electro-Submersible Pumps have been considered one of the main Artificial Lift Methods in different fields of the world due to their versatility in handling different well fluids and wide ranges of flow production. However, in many cases, it is not possible to reach the maximum potential of a well due to the perception of avoiding operating the Asynchronous Motors of the ESP system above 3600 RPM because it may induce failures.

During the operation of ESP systems, situations may occur during which it may be necessary to operate the motor above the standard frequency 50/60 Hz (3000/3600 RPM) and take advantage of the maximum potential of the well without requiring an immediate intervention. These situations include but are not limited to well productivity index differing from the expected, loss of mechanical transmission in some of the system components, or decrease in efficiency due to wear associated with equipment operation.

In the ESP industry there is a design practice of operating frequencies no higher than 60 Hz (3600 RPM) to avoid possible equipment failures associated with rotational instability, high temperatures or poor lubrication in the internal components due to greater friction at higher speeds. The recommended practices or international standards do not have an operating speed limit reference apart from the restrictions that can normally occur in the system, so there is uncertainty in the operating limits of these systems.

The main objective of this paper is to verify or disprove the theory of the high speed rotation in 500-series ESPs with Asynchronous Motors (standard technology) with a specific number of wells that were operated at speeds above 4000 RPM.

Published: August 2022

Human epidermal growth factor (hEGF) has multiple biological functions, and it is a very expensive polypeptide with attractive market prospects. However, the production of hEGF needs for high cost to manufacture polypeptide demands reinvestigations of process conditions so as to enhance economic benefits. Improving the expression of soluble hEGF is the fundamental method to reduce the cost. In this study, a non-secretion engineered strain of biosynthesized hEGF was constructed, using plasmid pET-22b(+) in Escherichia coli. Preliminary fermentation and high cell density cultivation were carried out in shake flasks and in a 5 L bioreactor, respectively. A high yield of 98 ± 10 mg/L of soluble hEGF and a dry cell weight (DCW) of 6.98 ± 0.3 g/L were achieved in shake flasks. Then, fermentation conditions were optimized for large-scale production, while taking into consideration the expensive equipment required for cooling and conforming to industrial standards. A yield of 285 ± 10 mg/L of soluble hEGF, a final cell density of 57.4 ± 2 g/L DCW (OD600 = 141.1 ± 4.9), and hEGF productivity of 14.3 mg/L/h were obtained using a bioreactor at 32 ℃ for 20 h. The production method developed in this study for the biosynthesis of soluble hEGF is efficient and inexpensive.
Organic geochemistry characteristics of the Permo-Carboniferous coals from the Huainan coalfield, East China: implications for paleoenvironmental changes
Authors: Cai Jiawei , Wang Ruwei , Huang Qing , Cai Feixuan , Yang Qiling
Published: August 2022

Climate–vegetation interactions belong to the most intriguing relationships in Earth’s history, especially for the late Paleozoic ice age with multiple icehouse-greenhouse climate transitions. Biomarkers preserved in coals provide evidence for potential taxonomic relationships among taxa with large scale paleoclimatic and paleofloral interpretations. In this study, we decipher the interactions among Permo-Carboniferous paleoclimate change and floral turnovers in the North China Craton. This is achieved by comprehensive investigation of the stratigraphic distribution of biomarkers in cored coals from Huainan coalfield, North China. Results indicated that the concentration and composition of biomarkers in coal, though irrevocably altered by diagenetic transformation and epigenetic activities, are closely related to the source of organic matter, depositional environment, and/or post-depositional change. The estimated molecular parameters of aliphatic and aromatic compounds are consistent with the maturity stage determined by Rock-Eval and organic petrology, which characterized the coals as high volatile bituminous A/B primarily consisting of mixed organic matters originating from marine algae and terrestrial higher plants. Enhanced maturity of coal results in the isomerization reactions of sterane isomers, tricyclic and tetracyclic diterpanes due to thermal stress and obscures the relationships between biomarker parameters and their biological precursors. The n-alkane distributions, though profoundly affected by thermal maturation, point towards the terrestrial higher plant inputs reflecting by the odd predominance of long-chain n-alkanes. The parallel stratigraphic patterns of C30 βα/(αβ + βα) with those of Pr/Ph ratios suggest that redox conditions is likely responsible for epimerization reactions of the hopane that converting βα to geologically preferred αβ isomers. The abrupt increase of 4- to 7-ring PAHs at the boundary of Lower and Upper Shihezi formations argue for a period of enhanced wildfire frequency. Moreover, the stratigraphic distribution patterns of biomarker parameters are consistent with the floral turnovers from initial warm and humid climate adaptive plant groups to semi-arid adaptive plant groups, and finally to dry climate adaptive plant groups.
The integration of rapid qualitative research in clinical trials: Reflections from the ward-based goal-directed fluid therapy (GDFT) in acute pancreatitis feasibility trial

Published: August 2022

Purpose
There has been an increase in the integration of qualitative studies in randomised controlled trials. However, many of these studies do not produce findings at a time when they can be used to inform decision-making processes on trial design and delivery, allowing for changes in real time. The purpose of this article is to address this gap by reflecting on our experience of carrying out a rapid qualitative study during a feasibility trial of goal-directed fluid therapy (GDFT) in patients with acute pancreatitis.
Methods
The study was designed as a rapid feedback evaluation and combined interviews with staff and patients who took part in the trial with a telephone audit of patients who declined participation.
Findings
: The rapid qualitative study pointed to common problems in trial recruitment among multiple sites, where lack of engagement of clinical teams across sites might impact negatively on patient recruitment. The study also pointed to issues encountered while implementing the trial that will be useful for informing the potential scale-up of the trial in the near future.
Conclusions
The rapid qualitative design can generate findings at a time when these can be used to inform changes in trial design and delivery. Additional research is required to explore the implementation of this research design in other settings and trial designs.
Capital Control and Heterogeneous Impact on Capital Flows
Authors: sanyal Anirban
Published: August 2022

Capital control is used as policy toolkit for safeguarding domestic economy from the volatility of capital flows. However, the effect of capital control is rather far fetched as the signaling effect of capital control can moderate investor’s outlook about domestic economy and thereby outweighs the intended effect. The spillover effect, on the other hand, modulates the capital flows to other countries when one country increases capital account restrictions. Further, the effect of capital control can have varying impact on capital inflows to different sectors as recent studies indicate heterogeneity in the drivers and nature of capital inflows to different institutional sectors. With the background, the paper analyzes the heterogeneous direct and spillover effect of capital control on gross capital flows across three major institutional sectors namely public, banks and corporate. The paper validates the possible heterogeneity in the effect of capital control on the capital inflows to these institutional sectors using spatial econometric models. The paper observes that the direct effect of capital control moderates portfolio inflows to public sector whereas the effect is insignificant on portfolio inflows to banks and corporate sector. Further, the paper observes that the spillover effect of capital control is broad-based i.e. equally prevalent on all sectors. The paper explains the heterogeneity in the capital control effects by introducing signaling effect in a portfolio choice model. The paper argues that the heterogeneous direct effect is driven by private signals of capital control received by the investors about the state of economy whereas the spillover effect of capital control is mainly driven by the hedging and search for better returns. The paper extends the existing literature of capital controls by reviewing the sectoral heterogeneity in the capital flows.

Introduction:
Breast cancer, the most common cancer in women, affects young women. Advance directives allow the expression of one's wishes concerning end of life wishes but they are poorly drafted. General practitioners report, in fact, real difficulties in talking about the end of life.
Purpose
This study aims to propose a model of advance directives that facilitates the exchange between the doctor and a breast cancer patient.
Methods
It is the result of a consensus of experts, obtained by the Delphi method. Twenty-one experts were included. A Delphi survey consisting of three rounds. The panel of experts were caregivers in contact with breast cancer patients, a Doctor of Sociology, deputy director of the National Center for Palliative Care and End of Life, as well as a former patient in remission from cancer. breast, association president. This new innovative model obtained takes into account in a more intimate way the moral values, the wishes of care and their environment.
Results
The first round lasted three weeks. Of the 29 questions posed to the experts, 20 were deemed relevant by over 70% of the experts. The second round lasted four weeks. Nine reworded questions were addressed to the experts. Eight of them were validated. The last question was validated in the third round. All experts responded to all three rounds.
Conclusion
The model created is a tool to create a more efficient dialogue between the physician and the patient. It is intended to be a faithful testimony of the patients’ wishes.

The metal additive manufacturing (AM) industry is actively developing instruments and strategies to enable higher productivity, optimal build quality, and controllable as-built microstructure. One of the beam controlling techniques, laser oscillation has shown potential in all these aspects in laser welding; however, few attempts have been made to understand the underling physics of the oscillating keyholes/melt pools which are the prerequisites for the these strategies to become a useful tool for laser-based AM processes. To address this gap, we utilized a synchrotron-based X-ray operando technique to image the dynamic keyhole oscillation in Ti-6Al-4V using a miniature laser powder bed fusion setup. We found good agreement between the experimental observations and simulations performed with a validated Lattice Boltzmann multi-physics model. The study revealed the continuous and periodic fluctuations in the characteristic keyhole parameters that are unique to the oscillating laser beam processing and responsible for the chevron pattern formation at solidification. Despite the intrinsic longer-range fluctuation, the oscillating technique displayed potential for reducing keyhole instability, mitigating porosity formation, and altering surface topology. The results provide important insights about the dynamics of the oscillating keyholes which are valuable guidelines for the future development and application of this technique.

The woody legume,Albizia lebbeck, is native to tropical Asia, Africa and Northern Australia. Owing to its multi utility, it is widely planted as block plantation and in boundary across community lands. A field study was conducted by measuring biometric value of trees,viz., height, diameter at every 2 meters height using tree telescope. Besides biometric attributes, age was assessed in order to correlate the age-wise yield. The study was carried out in western agro-climatic zone of Tamil Nadu in different age classes of trees,viz., 1–5 years, 6–10 years, 11–15 years, 16–20 years, 21–25 years, 26–30 years and 31–35 years. The uniqueness of the present study is that, the yield model construction for Albizia was done for standard stem timber (Volume at diameter 20 cm overbark) and standard stem small wood (Volume between diameter limits of 20cm and 5cm both measured overbark). After computing the data and subjected for multiple linear regression analysis, the model was constructed, so as to develop yield table accurately for Albizia without the help of form factor. The study result developed two exclusive yield models namely standard stem timber yield model for Albizia was Y= (-1.212) + (-0.012* Age) + (6.506*Diameter) and standard stem small wood was Y= (-0.945) + (-0.045*Age) + (2.769*Diameter) + (0.262* No. of Branches). The prominence of the present study is that yield table computation for Albizia is possible accurately without destructive analysis and the cumbersome process of developing form factor.

The Driver Behavior Questionnaire (DBQ) is one of the most used tools for measuring self-reported aberrant driving behavior. Several versions of the DBQ exist varying in terms of the item number and factor structure. This study aimed to investigate the psychometric properties and the factorial structure of the DBQ for assessing aberrant behavior among Lebanese drivers and to examine the relationship between DBQ subscales and socio-demographic characteristics and traffic-related variables. A cross-sectional study was conducted among Lebanese drivers aged more than 18 years old from all Lebanese governorates. Using a convenience sampling technique, data were collected using an anonymous Arabic, self-administered questionnaire that includes socio-demographic characteristics, and the Arabic Lebanese version of the DBQ (DBQ-L). Statistical analyses were performed using SPSS version 24 and Amos software. Exploratory factor analysis (N = 568) and confirmatory factor analysis (N = 534) were performed to test the factorial structure of the DBQ-L. Linear regression analyses were performed to examine the association between DBQ-L, sociodemographic and relevant traffic variables. A total of 1102 drivers aged between 18 and 82 years participated in this study with an average age of 34.64 (SD = 12.33). Of the total, 68.4% of participants were male having an average driving experience of 3.46 years (SD = 12.33). The DBQ-L total scale revealed high internal consistency (Cronbach’s α = 0.892). Exploratory and confirmatory factor analysis supported the original four-factor structure reflecting aggressive violations, ordinary violations, errors, and lapses dimensions. Aggressive violations had the highest mean among all the DBQ subscales. Men were found to have a higher tendency to commit aggressive and ordinary violations than females. Besides, the ordinary violation score was positively associated with younger age and increased mileage. All DBQ subscales decreased with the highest educational level. Being a professional driver increased the likelihood of drivers reporting violations, errors, and lapses, and increased mileage amplified the tendency of displaying aggressive violations and lapses when driving. However, errors decreased for young drivers and increased with age and larger driver experience. The cross-cultural adapted version of the DBQ was found to be a reliable and valid tool for assessing aberrant behaviors among Lebanese drivers. Further studies are needed to examine the ability of DBQ to predict road accidents.

Toona is a critical genus in the Meliaceae, and the plants of this group are an asset for both restorative and restorative purposes, the most flexible of which are Toona sinensis and Toona ciliata. To concentrate on the advancement of mitochondrial genome variety in Toona sinensis and Toona ciliata, the mitochondrial genomes of the two species were sequenced in high throughput independently, after de novo assembly and annotation to construct a mitochondrial genome map for comparison in genome structure, along with ML phylogenetic analysis with seven other Toona relatives. Results show:(1)The mitochondrial genome of Toona ciliata is 683,000 bp in length, with 45.40% GC content and circular structure, and contains 38 protein genes plus 33 transfer RNA genes, of which 33 tRNAs encode 20 amino acids. AT preference exists for MtDNA, TTT is the most frequently encountered codon, appearing 413 times, as well as the largest codon corresponding to The codon encoding the equivalent of Phe, which had the maximum content. (2)Mitochondrial genome of Toona sinensis is 638482bp in entire length, with 45.56% GC content and a circumscribed architecture, it encodes 38 protein genes and 34 transfer RNA genes, among 34 tRNAs embodying 20 amino acids. AT is preferred by mtDNA, whereas TTT, which is utilized 412 times quite often and seems to have the maximum Phe concentration, is the most frequently employed codon. (3)Both the mitochondrial genomes of Toona sinensis and Toona ciliata are highly preserved in terms of structural and functional genes, while the main variability is reflected in the length of tRNA and the number of genes. (4) In the ML evolutionary tree, Toona sinensis and Toona ciliata clustered individually into a small branch with 100% support, reflecting two species of Toona are very similarly related to each other. This research provides a basis for the exploitation of Toona sinensis and Toona ciliata in terms of medicinal, edible, and timber resources to avoid confusion; at the same time, it can explore the evolutionary relationship between the Toona and related species, which does not only have an important practical value, but also provides a theoretical basis for future hybrid breeding of forest trees, molecular markers, and evolutionary aspects of plants, which has great scientific significance.
