Imagen y creación, grupo de investigación que actúa en el noroeste de México
Authors: Huerta Jiménez Mayra
Published: May 2023

El grupo de investigación Imagen y Creación 1 conformado por profesores de la Universidad Autónoma de Baja California, ha generado durante siete años diversos proyectos. La intención de este ensayo es mostrar los eventos o sucesos académicos, que varían desde una exposición colectiva de gráfica, o fotografía hasta proyectos que involucran a estudiantes en procesos de creación con una serie de convicciones fuera del aula. Es decir, salir del recinto universitario, para abordar problemáticas de un contexto específico en la ciudad. Por nuestra ubicación geográfica, hablamos de un estado con dos ciudades fronterizas completamente distintas: la ciudad de Tijuana y Mexicali ambas con garitas que son los cruces con Estados Unidos, pero ambas mantienen singularidades por densidad de población, por densidad de deportados e inmigrantes que arriban para cruzar cada año. Por esta razón, el término frontera y migración son fenómenos que trascienden a todo el territorio. Mostraremos estos fenómenos con aspectos colaborativos y reflexivos para aportar al campo del arte con la realización de la práctica artística. Por otro lado, conformamos parte de una red temática en el Simposio de Investigación en Arte: Migrando, Interviniendo y Des-localizando con la Universidad Federal do Rio Grande do Sul y la Universidad Federal de Santa en la región de Porto Alegre, Brasil.Palabras clave: Creación; Frontera; Investigación; Acción; Red. Image and creation, a research group operating in northwestern Mexico.Abstract: The research group Image and Creation is made up of professors from the Universidad Autónoma de Baja California and which has generated various projects for seven years. The intention of this paper is to show events or academic productions, which vary from group shows featuring graphic design and photography to projects that involve students and their creative processes, as well as a series of convictions outside the classroom. These practices imply leaving the university campus to address problems in a specific urban context. Due to its geographic location, the paper talks about a state with two different border cities: the city of Tijuana and Mexicali, both having their own United States Customs and Border Protection agencies, serving as the border crossing point, but both maintaining their own unique characteristics, due to population density and the density of deportees and immigrants who arrive each year. For this reason, the term border and migration can be seen as phenomena that transcend the entire territory. We will show the collaborative and reflective aspects of these phenomena, and how they contribute to the field of art and artistic practice. This paper has been produced as part of a thematic network of the Art Research Symposium: Migrating, Intervening and Relocating with the Federal University do Rio Grande do Sul and the Federal University of Santa in the region of Porto Alegre, RS, Brazil. Keywords: Creation; Frontier; Research; Network; Action.

Authors: Zhao Yuhao , Guo Zongsheng , Liu Zheng , Yang Xinchun , Zhao Lei
Published: May 2023

Background: The purpose of this study was to explore whether consideration of FIB levels might improve the predictive value of the ACEF score in patients with ACS.

Methods: A total of 290 patients with ACS were enrolled in this study. The clinical characteristics and MACE were recorded.

Results: Multivariate logistic regression analysis revealed that the FIB level (odds ratio=7.798, 95%CI, 3.44–17.676, P<0.001) and SYNTAX score (odds ratio=1.034, 95%CI, 1.001–1.069, P=0.041) were independent predictors of MACE. On the basis of the regression coefficient for FIB, the ACEF-FIB was developed. The area under the ROC of the ACEF-FIB scoring system in predicting MACE after PCI was 0.753 (95%CI 0.688–0.817, P<0.001), a value greater than those for the ACEF score, SYNTAX score and Grace score (0.627, 0.637 and 0.570, respectively).

Conclusion: ACEF-FIB had better discrimination ability than the other risk scores, according to ROC curve analysis, net reclassification improvement and integrated discrimination improvement.
Listening to Layers of Loss
Authors: Brooks Maegan Parker
Published: May 2023

Reflecting on the recent losses of her sister, father, and mother in the midst of the global pandemic, the author moves from acquaintance-level grief communication encounters through grief communication with friends, family, and, ultimately, the self-communication that has sustained her during this intense period of bereavement. Building upon scholarship in autoethnography, family communication, grief, and trauma studies, moreover, the author shares bereavement practices that have helped her process loss. Following her personal narrative, she provides seven offerings to encourage the bereaved reader and support their grief writing. The essay concludes by challenging assumptions of U.S. culture’s “grief illiteracy,” with a call for white writers, in particular, to interrogate the social scripts and systems of power and privilege manifest in their grief communication. Moreover, the author encourages all autoethnographers to build systemic critique from their multilayered personal considerations of grief and post-traumatic growth.

Published: May 2023

Objective: to investigate the actions of nurses in regard to lesbian and bisexual women in the context of the National Policy for the Integral Health of Lesbians, Gays, Bisexuals, Cross-Dressers and Transgender Persons. Methods: qualitative study involving 25 nurses from the Family Health Strategy, contacted via electronic means. We applied a form containing sociodemographic data and an investigation of actions in primary health care, as well as a thematic content analysis. Results: we found there are professional capacitation activities, embracing of demands, and enhanced interprofessional work. Nonetheless, there were shortcomings in the knowledge regarding health care towards lesbian and bisexual women. Conclusion: there are still prejudices, difficulty to access, and little attendance of lesbian and bisexual women in health services, as well as a deficit in the support to health actions and lack of monitoring. Contributions to practice: the importance of the scientific, professional, and social experiences stand out, regarding the need to humanize the care to lesbian and bisexual women. It is a supporting material for researchers and nursing professionals, enabling them to direct their care to a holistic and integral care to be provided to these women, in addition to being an encouragement to further comparative studies.

Published: May 2023

Objective: to understand the perception of the LGBTQIA+ elderly person about social and programmatic vulnerability. Methods: qualitative study developed with ten elderly persons. The collection was done through an interview supported by a semi-structured instrument. Elderly people of both sexes and non-binary assisted in a reference center were included. We adopted content analysis through the thematic modality for data systematization. Results: human aging raised discussions about specific needs, such as sexuality. Treated as taboos, elderly individuals who belonged to sexual minority groups suffered double invisibility, especially in health services. Furthermore, the lack of social and family support resulted in psychological suffering and social vulnerability. Conclusion: through the reports, it is possible to identify important gaps in the assistance to the LGBTQIA+ elderly person, such as difficulty of access and generic health practices, which do not consider the particularities of this population, as well as discrimination and lack of spaces for coexistence. Contributions to practice: population aging raises discussions about the adequacy of health services in the face of the specific demands of the elderly, especially regarding sexuality and sexual and gender minorities.
100 years of glucagon anniversary
Authors: Cantley James , Poitout Vincent , Hull-Meichle Rebecca L
Published: May 2023

The year 2023 marks 100 years since publication of the first report of a hyperglycemic factor in pancreatic extracts which C P Kimball and John R Murlin named glucagon (from GLUCose AGONist). Glucagon has a range of profound effects on metabolism including, but not limited to, stimulation of hepatic glucose production. Dysregulation of glucagon secretion is a key feature of both major forms of diabetes, leading to the concept that diabetes is a bihormonal disorder. Still, the work to fully understand the production and biological effects of glucagon has proceeded at a slower pace compared to that of insulin. A recent resurgence of interest in the islet alpha (α) cell, the predominant site of glucagon production, has been facilitated in part by technological innovations. This work has led to significant developments in the field, from defining how alpha cells develop and how glucagon secretion from pancreatic alpha cells is regulated to determining the role of glucagon in metabolic homeostasis and the progression of both major forms of diabetes. In addition, glucagon is considered to be a promising target for diabetes therapy, with many new potential applications arising from research in this field. This collection of reviews, led by Guest Editors James Cantley, Vincent Poitout and Rebecca Hull-Meichle, is intended to capture the field’s current understanding of glucagon and alpha cell biology, as well stimulate additional interest and research on this important hormone.

Published: May 2023

For effective conservation management, it is crucial to comprehend the diversity, abundance, and distribution of the forest as wildlife habitat. The fundamental composition of the forest is significantly influenced by the ecological features of the sites, species diversity, and rate of tree species regeneration. This finding aimed to assess the diversity, abundance, and distribution of tree species as suitable habitat for wildlife species and for sustainable forest management, climate change mitigation, and environmental resilience. The study was conducted in dry season (between 5th September, 2021 and April, 2022). Purposive sampling techniques and systematic line transects were used for data collection and plot delineation. There were laid 8 transects, each 1000 meters long and 500 meters apart. Descriptive statistics such as mean, frequencies, and percentages were used to analyze the data. Correlation analyses and diversity indices were carried out using the R programming software. In the study area, 68 tree species from 34 families were found. Meliacea (6 trees per ha), Caesalpiniceae, and Moracea (5 trees per ha) were the three most common tree species in the study area. Melicia excelsa showed the highest relative frequency (2.256%) and (2.241%). The species Bialonella toxisperma had the highest relative dominance (4.970%). In Melicia excelsa, IVI recorded the highest value (4.970%). The tallest tree and Dbh (Diameter at Breast Height) measured 80.5 cm and 68.3m). The Margelef index was 36.10, the Shannon Wiener index was 5.058, and species richness was 68. However, the high proportion of smaller-diameter trees in the forest reserve implies that, it is strong and healthy. Since natural areas play a critical role in slowing down climate change, strict oversight of these areas should be strongly encouraged.

Authors: Grandjean-Blanchet Charlotte , Le Cathie-Kim , Villeneuve Stephanie , Cada Michaela , Beck Carolyn E. , Science Michelle , Rosenfield Daniel , Ostrow Olivia
Published: May 2023

OBJECTIVES

There is a lack of guidance on the management of febrile neutropenia in otherwise healthy children, including the need for hospitalization and antibiotic administration, leading to significant practice variation in management. The aim of this initiative was to decrease the number of unnecessary hospitalizations and empirical antibiotics prescribed by 50% over a 24-month period for well-appearing, previously healthy patients older than 6 months presenting to the emergency department with a first episode of febrile neutropenia.

METHODS

A multidisciplinary team of stakeholders was assembled to develop a multipronged intervention strategy using the Model for Improvement. A guideline for the management of healthy children with febrile neutropenia was created, coupled with education, targeted audit and feedback, and reminders. Statistical control process methods were used to analyze the primary outcome of the percentage of low-risk patients receiving empirical antibiotics and/or hospitalization. Balancing measures included missed serious bacterial infection, emergency department (ED) return visit, and a new hematologic diagnosis.

RESULTS

Over the 44-month study period, the mean percentage of low-risk patients hospitalized and/or who received antibiotics decreased from 73.3% to 12.9%. Importantly, there were no missed serious bacterial infections, no new hematologic diagnoses after ED discharge, and only 2 ED return visits within 72 hours without adverse outcomes.

CONCLUSIONS

A guideline for the standardized management of febrile neutropenia in low-risk patients increases value-based care through reduced hospitalizations and antibiotics. Education, targeted audit and feedback, and reminders supported sustainability of these improvements.
Pediatric Antiretroviral Therapy Coverage and AIDS Deaths in the “Treat All” Era
Authors: Rosen Joseph G. , Muraleetharan Ohvia , Walker Allison , Srivastava Meena
Published: May 2023

OBJECTIVES

In 2015, CD4-based clinical staging criteria for antiretroviral therapy (ART) initiation were removed, expanding ART eligibility (“Treat All”) for children, who shoulder an outsized burden of HIV-related deaths. To quantify the impact of “Treat All” on pediatric HIV outcomes, we examined shifts in pediatric ART coverage and AIDS mortality before and after “Treat All” implementation.

METHODS

We abstracted country-level ART coverage (proportion of children <15 years on ART) and AIDS mortality (deaths per 100 000 population) estimates over 11 years. For 91 countries, we also abstracted the year “Treat All” was incorporated into national guidelines. We used multivariable 2-way fixed effects negative binomial regression to estimate changes in pediatric ART coverage and AIDS mortality potentially attributable to “Treat All” expansion, reported as adjusted incidence rate ratios (adj.IRR) with 95% confidence intervals (95% CI).

RESULTS

From 2010 to 2020, pediatric ART coverage tripled (16% to 54%), and AIDS-related deaths were halved (240 000 to 99 000). Compared with the pre-implementation period, observed ART coverage continued increasing after “Treat All” adoption, but this rate of increase declined by 6% (adj.IRR = 0.94, 95% CI: 0.91–0.98). AIDS mortality continued declining after “Treat All” adoption, but this rate of decline decreased by 8% (adj.IRR = 1.08, 95% CI: 1.05–1.11) in the post-implementation period.

CONCLUSIONS

Although “Treat All” called for increased HIV treatment equity, ART coverage continues lagging in children and comprehensive approaches that address structural issues, including family-based services and intensified case-finding, are needed to close pediatric HIV treatment gaps.

Authors: Guo Liping , Wang Suli , Melnychuk Sergiy , Ma Hanjun
Published: May 2023

Introduction. Maternal vitamin D3 levels have long lasting consequences on meat quality and growth performance. The present study was conducted to investigate maternal vitamin D3 status in sows during pregnancy on meat quality attributes, chemical composition, and low field nuclear magnetic resonance (LF-NMR) T2 relaxation times of longissimus dorsi muscle in offspring pigs.
Materials and methods. A total of 27 sows (41st day of pregnancy) were randomly allotted to low (LD), normal (ND), and high (HD) dietary vitamin D3 groups (containing 200, 800 and 3200 IU of vitamin D3/kg experimental diet, respectively). In each group were 3 replicates with 3 sows per replicate. From parturition to weaning, all lactating sows fed the ND diet. At 150 days of age, six offspring pigs in each group (2 offspring pigs with similar body weight per replicate, gender balanced) were selected and slaughtered to evaluate pork quality characteristics.
Results and discussion. The results showed that maternal vitamin D3 supplementation decreased L*, b* value, shear force, cooking loss, T21 and T22 relaxation times, while increased a* value, pH value, water holding capacity (WHC), crude protein (CP), crude fat (CF), calcium (Ca), and phosphorus (P) content in longissimus dorsi muscle of offspring pigs. These results demonstrated that high-dose maternal vitamin D3 level could improve meat quality characteristics of offspring pigs, and it will provide a scienfific basis for the early nutritional regulation of offspring prok quality.
Conclusions. The findings indicated that maternal vitamin D3 supplementation has positive effects on quality characteristics of longissimus dorsi muscle, and improved eating quality of meat in offspring pigs.
APPLE JUICE CLARIFIED BY THE POLYMERIC FLOCCULANTS
Authors: Pogrebnyak A. , Perkun I. , Korneyev М. , Haponenko S. , Pogrebnyak V.
Published: May 2023

Based on the research, a innovative method for processing apple juice has been proposed, which consists in the use of safe polymeric flocculants – polyethylene oxide and hydrolyzed polyacrylamide, which can increase the speed and degree of transparency and purification of apple juice from heavy metals in conditions of its turbulent flow in channel, which is the gap between the stator with inlet and outlet pipes and the rotor kinematically connected to the electric motor. The mechanism of increasing the flocculating ability of flocculants under conditions of detected turbulent transparency of apple juice makes it possible to develop ways to improve the consumer properties of both the flocculant and apple juices during transparency. A comprehensive assessment of the quality of apple juice illuminated by hydrodynamically activated polyethylene oxide and hydrolyzed polyacrylamide was carried out, namely: the features of changes in mineral, vitamin, physical and chemical composition and safety, which together form the nutritional value and consumer properties of the product, were studied. The results of sensory and qualimetric analysis of apple juice clarified by activated flocculants indicate that when apple juices are illuminated with polyethylene oxide and hydrolyzed polyacrylamide, changes are observed primarily in transparency and color. The obtained quantitative data characterizing the physical and chemical composition of apple juice and the content of heavy metals in apple juice clarified with hydrodynamically activated polyethylene oxide and hydrolyzed polyacrylamide meet the requirements for apple juice producers. The research results allow us to conclude that polymeric flocculants polyethylene oxide and hydrolyzed polyacrylamide are effective reagents that can be used for deep purification of apple juices from heavy metals. Based on the obtained data characterizing the residual concentration of polyethylene oxide in apple juice treated with polyethylene oxide with hydrodynamic activation in a flocculator, it was concluded that the hydrodynamic activation of the flocculant reduces its residual concentration by more than 1.5–2 times.

Authors: Gritsenko O. V. , Chumakova G. A. , Gruzdeva O. V. , Subbotin E. A.
Published: May 2023

Aim. To study the factors preventing the LVDD in obese patients.

Material and methods. The study included 101 obese men who initially did not have LVDD. After 4,7±0,3 years, anthropometric parameters (body mass index (BMI), hip circumference (HC), waist circumference (WC)) and LV diastolic function were reassessed. All patients at the time of enrollment were assessed for the level of neurohumoral (leptin, adiponectin, leptin receptor), pro-inflammatory (tumor necrosis factor-α, interleukin-6, -10, C-reactive protein) and profibrotic factors (collagen type I and III, matrix metalloproteinase-3, vascular endothelial growth factor, transforming growth factor β).

Results. During 4,7±0,3 years of follow-up, 26,7% of the total number inclu­ded in the study registered a decrease in body weight. A tendency to a de­crease in epicardial fat thickness (EFT) by 0,5 mm (7,49 (6,00; 9,00) mm at the time of inclusion and 7,04 (6,00; 9,00) mm over time (p=0,13)). According to echocardiography, LVDD was detected in 20 patients (19,8% after 4,7±0,3 years). Comparative analysis of baseline anthropometric parameters, EFT and after 4,7±0,3 years in groups of patients with (DD+) and without (DD-) LVDD revealed a significant decrease in body weight (p=0,03), BMI (p=0,02), WC (p=0,04) and EFT (p=0,002) only in the DD- group. Patients who developed LVDD initially had increased tumor necrosis factor-α (p=0,02), interleukin-6 (p=0,01), free fatty acids (p=0,001), type I collagen (p=0,001), type III collagen (p=0,02) and a decrease in adiponectin level (p=0,001).

Conclusion. Thus, in patients with a decrease in weight, BMI, WC and EFT during the follow-up period of 4,7±0,3 years, LVDD did not develop, which is associated with a reduced risk of myocardial lipotoxicity against the background of epicardial obesity.

Published: May 2023

Aim. To study the prognostic role of neutrophil gelatinase-associated lipocalin (NGAL) as a marker of adverse cardiovascular events (CVEs) in patients with coro­nary artery disease (CAD) associated with abdominal obesity (AO).

Material and methods. This 12-month prospective study included 68 patients diagnosed with CAD who were hospitalized for elective percutaneous coronary intervention (PCI). The median age was 61 [55;65] years. Depending on the presence of obesity according to the World Health Organization (1999) criteria, patients were divided into 2 groups. The 1st group included 30 patients with AO, while the 2nd group — 38 patients without obesity. Patients were measured for waist circumference and hip circumference, and waist-to-hip ratio was calculated. Lipid profile and NGAL concentration were determined. During the study, body mass index (BMI), visceral adiposity index (VAI), triglycerides (TG)/glucose index, lipid accumulation product (LAP), metabolic index (MI), TG to high-density lipoprotein cholesterol ratio (HDL-C). During this period, data was collected on the disease course and intervention outcome. After 12 months an extended examination was performed to assess the endpoints.

Results. During the follow-up period, unfavorable cardiovascular events in the 1st group of patients were registered in 33,3% of patients, and in the 2nd group — in 26,3%. In the group of patients with obesity, higher values of anthropometric indices and NGAL were established. The concentration of NGAL has the highest correlation with BMI, MI, LAP and slightly less with total cholesterol and VAI levels. The analysis showed that NGAL >47,1 ng/ml is a predictor of adverse CVEs in patients with CAD and obesity after PCI.

Conclusion. Thus, NGAL has the highest correlation with the following indices: BMI, MI, LAP, total cholesterol, and VAI. NGAL >47,1 ng/ml is a predictor of adverse CVEs in patients with CAD and obesity after PCI. NGAL may serve as a promising marker for predicting adverse CVEs. This biomarker already at the stage of hos­pitalization can assess the risk adverse outcomes in patients with CAD and AO, including those who underwent PCI.

Purpose – Business groups in Korea and Japan have different national environments. It will be possible to examine how their corporate governance affects performance and finance, and how it affects economic development and innovation through literature research related to the field of international management. Design/Methodology/Approach – This study reviewed domestic and foreign papers related to keiretsu and chaebol from 2001 to 2020. As a result, we selected and analyzed 39 foreign journals and 6 domestic journals, a total of 45 papers. Findings – It was found that interest in the impact of each factor on corporate performance, such as internationalization, resources and capabilities, business group attributes, and corporate governance, was high. It was found that research related to Asian business groups, especially chaebol and keiretsu, is so closely related to corporate performance that it cannot be considered separately. However, domestic journals only focused on chaebol research, and there was no research on keiretsu. Research Implications – It is expected that the roles and discussions of business groups will be expanded by reviewing existing literature on Korea’s chaebol and Japan's keiretsu among business groups, and reviewing comparative literature under different corporate governance structures. In addition, it will serve as an opportunity to identify the direction of academic research through a literature review of business groups in the two countries.
Lexical comprehension within and across sign languages of Belgium, China and the Netherlands
Authors: Börstell Carl
Published: May 2023

There are hundreds of known sign languages around the world today, distinct languages each with its own historical and cultural context. Nevertheless, it is well known among signers who move through international spaces and across signing communities that a certain degree of mutual intelligibility is achievable during so-called cross-signing, even between historically unrelated sign languages. This has been explained by shared experiences, translanguaging competence and a higher degree of iconicity in the lexicons of sign languages. In this paper, I investigate one aspect of mutual intelligibility between four different sign languages: Sign Language of the Netherlands (NGT), Flemish Sign Language (VGT), French-Belgian Sign Language (LSFB) and Chinese Sign Language (CSL). Through a comprehension task with NGT signs, I analyze how accurately signers of the four sign languages identify NGT signs in an experimental sign-to-picture matching task, matching one target sign to one of four meaning choices: one target meaning and three distractors based on either form-similarity or plausible iconicity-mapping to the target sign. The results show that signers of VGT and LSFB perform better than CSL signers on this task, which may be attributed to lexical overlap, shared iconic mappings and experiences, as well as language contact due to geographic proximity. It is found that misidentification of target meanings is mostly caused by distractors with iconically plausible mappings between form and meaning. Across the four languages, signers’ self-evaluations of their performance on the lexical comprehension task correlate with test scores, demonstrating that they generally judge their level of comprehension accurately.

Simple TCA/acetone protein extraction protocol for proteomics studies. v1
Authors: José Rinaldi Angelo
Published: May 2023

Protein extraction with TCA (trichloroacetic acid) and acetone is a widely used method to precipitate proteins from biological samples. This method is useful for obtaining proteins of interest for proteomic studies or biochemical analyses. Here are some reasons why TCA/acetone protein extraction is important: Selective Protein Precipitation: TCA/Acetone is effective in selective protein precipitation, allowing the removal of contaminants and unwanted components present in the sample. This is especially important in proteomic studies, where protein purity is critical for subsequent analyses. Removal of lipids and carbohydrates: TCA/acetone is efficient in removing lipids and carbohydrates, which can interfere with proteomic and biochemical analyses. These compounds are precipitated together with the proteins, facilitating their removal and improving the quality of the samples. Preservation of protein structure and function: The use of TCA/acetone for protein extraction can preserve protein structure and function. These precipitating agents do not denature proteins, allowing analysis of proteins in their native or active form. Simplified sample processing: Protein extraction with TCA/acetone is relatively simple and fast, providing a convenient approach to processing biological samples. This is especially advantageous when working with large numbers of samples or in situations where time is critical. In summary, protein extraction with TCA/acetone is an important and versatile method that allows obtaining high quality proteins for various analyzes and studies. Its efficiency in removing contaminants, preserving protein structure and simplicity make it an essential technique in biomedical and biotechnological research.

6.Taxon Group: Colonial Ascidiacea v1
Authors: Bishop John
Published: May 2023

This is part of the collection "DToL Taxon-specific Standard Operating Procedures (SOPs) for Marine Metazoa", lead by the Other Metazoa Working Group. The SOP collection contains guidance on how to process the various marine Metazoa species within the scope of the Darwin Tree of Life project. The guidance specifically refers to the tissue samples needed for DNA barcoding (which takes place at the Natural History Museum (NHM) and at the Marine Biological Association (MBA)) and outlines the dissected tissues required for whole genome sequencing, which takes place at the Wellcome Sanger Institute. Every specimen is submitted for DNA barcoding first before potentially being sent to the Wellcome Sanger institute. Definition: Colonial ascidians are when multiple individual ascidians live and interact closely with each other. Each individual in the colony has its own intake siphon for feeding, but several individuals may combine to share one exit siphon. Including: Families Didemnidae, Polyclinidae, Polycitoridae, Holozoidae,Clavelinidae, Perophoridae, Diazonidae, colonial Styelidae Excluding: Unitary (= ‘solitary, non-colonial) Ascidiacea; for this, see separate SOP in the collection.

Published: May 2023

On 6 February 2023, southeastern Türkiye experienced two Mw 7.7 and 7.6 earthquakes. The earthquake sequence caused widespread damage and tens of thousands of casualties in Türkiye and Syria. We analyze mainshocks and aftershocks, combining complementary source characterization techniques, relying on local, regional, and teleseismic data. Backprojection analysis and finite source inversion for the mainshocks resolve coseismic slip, rupture length, and propagation mode along the main faults, whereas centroid moment tensor inversion for 221 aftershocks resolves details of the fault network. The first mainshock nucleated on a splay fault and activated the neighboring East Anatolian fault zone (EAFZ). It ruptured bilaterally along ∼500 km first toward northeast and later to south-southwest on multiple, previously partly dormant fault segments. The second mainshock ruptured the east–west-oriented Sürgü-Misis fault zone (SMFZ), reaching a slip of 7 m. The analysis of aftershocks with heterogeneous moment tensors retrospectively reconstructs rupture details. Along the main strand of the EAFZ, they map the geometry of different segments in unprecedented detail, whereas along the SMFZ they illuminate the geometry and behavior of large structures for the first time. Our work sheds light on multiple aspects of rupture evolution and provides new insights into the devastating earthquake sequence.

The Relationship between Transformational Leadership, Educators’ Confidence in their Heads of Schools and Educators’ Dedication at Work in Secondary Schools of Mauritius
Authors: Ibrahim Codaboccus Mohammud Khalil
Published: May 2023

In Mauritian secondary schools (colleges), very limited studies exist regarding the influence of transformational leadership applied by rectors on educators’ trust in their leaders and their degree of commitment to their work. Objectives: to determine (a) (i) the levels of transformational leadership applied by rectors of secondary schools in Mauritius, (ii) the degree of trust of these educators in their rectors, (iii) the degree of educators’ commitment to their duties; (b) the relationship and influence of transformational leadership applied by schools leaders over (i) educators’ trust in their rectors, (ii) educators’ degree of commitment toward their work; (c) the existence of any relationship between educators’ trust and their commitment toward their duties. Method: Data was collected from 394 respondents across Mauritius during December 2022 using simple random sampling through an online survey. Analysis on SPSS 25 was carried out for correlations. Results: All three variables’ levels were rated as “high” and were significantly and positively correlated: (i) there was a significant positively moderate correlation between the level of transformational leadership applied in colleges and the degree of educators’ trust in their heads of schools; (ii) there was a significant positively low correlation between the level of transformational leadership applied in colleges and the degree of educators’ commitment to their work. Additionally, it was found that there was a significant positively weak correlation between the degree of educators’ trust in their heads of schools and the degree of educators’ commitment to their work.
GLAMPİNG İŞLETMELERİNDE ASGARİ STANDARTLARIN BELİRLENMESİ: KEŞFEDİCİ BİR NİTEL ÇALIŞMA
Authors: Gök Burcu , Özhasar Yunus
Published: May 2023

Son yıllarda özellikle yoğun geçen iş yaşamından uzaklaşmak, salgın hastalık riskinden korunmak gibi nedenlerle insanların doğayla iç içe olan konaklama işletmelerine yönelmektedir. Bu sebeple glamping işletmeleri sıklıkla tercih edilmeye başlanmıştır. Kısaca lüks kampçılık olarak adlandırılabilecek glampinglerle ilgili standartların oturmamış olması turizm sektöründe bir belirsizlik yaratmaktadır. Bu çalışmada Türkiye’deki glamping işletmelerinin sahip olması gereken asgari standartların yerli turistlerin bakış açısına göre belirlenmesi amaçlanmıştır. Buna bağlı olarak amaca yönelik örnekleme yöntemi kullanılmış ve daha önce Türkiye’de faaliyet gösteren glamping işletmelerinde en az bir kez konaklamış olan 12 katılımcıyla yarı yapılandırılmış çevrimiçi görüşmeler yapılmıştır. Bu görüşmelerden elde edilen veriler tema kategori ve kodlara ayrılarak betimsel bir analize tabii tutulmuştur. Çalışmada glamping işletmeleri katılımcılar tarafından oda, banyo, mutfak, ortak kullanım alanları, konum, sunulan hizmetler gibi unsurlar bakımından değerlendirilmiştir. Araştırma sonuçlarına göre katılımcıların glamping işletmelerinden öncelikli olarak kamp ve lüks deneyimini birleştirecek şekilde konaklama sırasında ihtiyaç duyulacak konforlu yatak, ücretsiz ikram, klima, banyo, havlu gibi ürün ve hizmetleri talep ettiği görülmüştür. Bunun yanı sıra katılımcıların glamping işletmelerinin ağırlıklı olarak organik besinlerden oluşan yeme-içme imkânı, kolay ulaşılabilirlik, güvenli olma, denize sıfır ya da orman konumunda yer alma gibi hizmetleri sunmaları beklentisinde oldukları anlaşılmaktadır.
