The Effect of Various Molotov Cocktails on Different Surfaces and Evaluation of Fire Changes
Authors: Yıldırım Zeliha , Uysal Cem
Published: July 2024

Objective:Molotov cocktails are a classic homemade weapon used over the past 80 years; also known as gasoline bombs. However, there is not enough research in the literature. Molotov cocktail is classified as a mildly explosive substance. But a Molotov cocktail is not an explosive. This is a handmade lighter. It is used to set fire to targets in terrorist attacks.
Methods:In our study, classic homemade Molotov cocktails were used. Oil, diluent, sugar, cologne, epoxy resin, paraffin, egg white, liquid and solid detergent, bleach, wood glue were added to the mixture. Parameters such as burning temperature, burning time, glass and nail spreading diameter, and residues of the Molotov cocktail were investigated. The prepared molotov cocktails were broken on 5 different floors, and the effect of changing the floor on the parameters was investigated.
Results:In our study, 51 (59.3%) of 86 molotov cocktails were broken. Most of the destruction occurred in the wall. According to the results we obtained, a relationship was found between the content of the Molotov cocktail, the burning temperature and the time. It was found that the damage was increased with the addition of substances to the mixture.
Conclusion: In addition, in our study, it was noticed that the Molotov cocktail did not explode by itself and did not cause damage to the environment by throwing nails.

Authors: Onur Hakan , Rahmanali Onur Arzu
Published: July 2024

Objective: Determination of the frequency of Rotavirus and Adenovirus in patients diagnosed with gastroenteritis in the Pediatric Polyclinic of our hospital by immunochromatographic method and retrospective evaluation of the change in the distribution of the agent according to age, gender and vaccination status.
Method: Those patients with complaints of diarrhea, vomiting, dehydration, and fever as well as those diagnosed with acute gastroenteritis were evaluated by taking fresh stool samples between January 2015 and November 2020. The data were presented using descriptive statistics.
Results: The number of acute gastroenteritis patients included in the study was 1,192. The mean age of the patients was 18±SD months (min: 1 month, max: 180 months). Adenovirus and Rotavirus antigens were detected in 10% of all cases (n=119). Rotavirus antigen was positive in 6.6% (n=78) and Adenovirus antigen was positive in 3.1% (n=38) of all cases. The hospitalization rate was 5.1 times higher in Rotavirus positive cases (p<0.001). It was observed that fever and vomiting were statistically higher in patients with Adenovirus or Rotavirus positive. (p=0.001).
Conclusion: It has been shown that Rotavirus should be kept in mind, especially in children with severe vomiting/diarrhea leading to dehydration. Therefore, Rotavirus vaccination is very important in early childhood.

Published: July 2024

Objective: This study aimed to compare the thiol/disulfide balance, myeloperoxidase, and ischemia-modified albumin levels in the follicular fluid (FF) of poor ovarian response (POR) and normal ovarian response (NOR) women who received intracytoplasmic sperm injection (ICSI).Methods: The study was performed between March 2021 and April 2022 at the Department of Obstetrics and Gynecology, Center for Reproductive Medicine, Ankara City Hospital. The study included 27 POR and 35 NOR women who underwent ICSI. FF was obtained after the controlled ovarian stimulation cycle. The FF thiol/disulfide balance was detected using spectrophotometric methods. A correlation analysis was conducted to determine whether these oxidative stress markers could contribute to predicting oocyte quality.Results: Disulfide levels were significantly higher in the NOR group than in the POR group (p=0.014). The number of fertilized egg (2PN) oocytes was positively correlated with the total thiol level (r=0.258, p=0.046). The disulfide level was positively correlated with the anti-Müllerian hormone level (r=0.262, p=0.039) and the total number of retrieved oocytes (r=0.335, p=0.008).Conclusion: The disulfide levels differed significantly between the NOR and POR groups. The statistically significant differences of fewer metaphase II oocytes and lower percentage of good-quality embryos in the NOR group compared to the POR group might have resulted from the NOR group’s elevated disulfide levels. The total thiol levels correlated with the total of 2PN oocytes. Future studies should examine the thiol/disulfide balance at assisted reproductive technology centers to predict which oocytes could be fertilized.

Published: July 2024

We present a rare case of severe ovarian hyperstimulation syndrome (OHSS) in a 19-year-old woman undergoing a second donation cycle of controlled ovarian hyperstimulation. The patient developed severe OHSS despite the implementation of preventive strategies and required hospitalization for 14 days, including treatment in the intensive care unit. The underlying pathophysiology that triggers this extreme systemic response in certain patients, despite the implementation of preventive measures, remains unknown. Continued research efforts are necessary to improve our understanding and management of this condition.
First Report for Painted Globular Frog Uperodon taprobanicus in North Bastar Kanker District of Chhattisgarh, (India)

Published: July 2024

The North Bastar Kanker is full of natural wealth where different types of species are found every year, out of which new species are found the Painted Globular Frog (Uperodon taprobanicus) has been seen for the first time, according to the current study. One year of observation throughout the village badgaon near Khandi Rivershowed this species to be present in this microhabitat. The species' taxonomic validity in the area was aided by morphological and photographsanalysis that validated its identification. The known distribution range of U. taprobanicus, which was previously primarily reported in South India and Sri Lanka, is expanded by this finding. In order to shed light on the state of the species' conservation in this area, ecological characteristics like habitat choice, microhabitat usage and potential threats were also evaluated. The exploration underscores the importance of continued monitoring and conservation efforts to safeguard the diversity of amphibians in Chhattisgarh and highlights the need for further research to elucidate the ecological requirements and population dynamics of U. taprobanicus in its newly identified habitat. This species has been marked in the IUCN data and its conservation is very important in time. If we cannot conserve it, then we will eliminate this species from our ecosystem and we may see natural calamity and loss in the near future.
Developing the green operating room: exploring barriers and opportunities to reducing operating room waste
Authors: Pillay Ludmilla , Winkel Kenneth D , Kariotis Timothy
Published: July 2024

The Australian health care system contributes 7% of the national greenhouse gas emission footprint and generates massive waste streams annually. Operating rooms are a particular hotspot, generating at least 20% of the total hospital waste.

A systematic search of several global academic databases was conducted in mid‐2022 (articles from 1992 to 2022) for peer‐reviewed research relevant to waste management in the operating rooms. We then used thematic analysis to enumerate and characterise the strategies and barriers to sustainable waste management in the operating room.

The waste reduction strategies focused on avoidance of high carbon products; correct waste segregation and reduced overage; reusing, reprocessing, and repurposing devices; and improved recycling. The first barrier identified was a constrained interpretation of the concept of “first do not harm”, ingrained in surgeons’ practices, in prioritising single‐use surgical products. The second barrier was ineffective or insufficient waste education. The third barrier was the immediate cost of implementing waste management compared with the long term realisation of environmental and economic benefits. The last barrier to implementing institutional practice change was the lack of policies and regulations at the local hospital, federal and international levels.

We also evaluated the knowledge gaps in current surgical waste research, including lack of benchmarking data and standardised regulations concerning reusable or reprocessed devices, as well as the methods used to promote pro‐sustainability behavioural change.
Using Stable Nitrogen Isotope Ratios from Human Skeletal Muscle Tissue for Postmortem Interval (PMI) Estimation (Part 1)
Authors: Beasley Melanie , Lesnik Julie , McKee-Zech Hayden , Duncan Anielle
Published: July 2024

Human skeletal muscle tissue was analyzed for stable nitrogen isotope analysis (δ15N) to test the applicability of changes in values (Δ15N) through the putrefaction process for postmortem interval (PMI) estimation. Seasonal differences in Δ15N values of decom-posing skeletal muscle tissue were analyzed from 20 human donors at the University of Tennessee Anthropology Research Facility. This study revealed that change in the δ15N ratios of decomposing muscle tissue has potential as a novel method for PMI estimation. In winter months, when identifiable muscle tissue can be retained on a body for months, the data indicate that there is a systematic increase in Δ15N values with increasing temperatures when putrefaction progresses faster with values shifting as much as 3.0‰. This initial study indicates there is value in further method development of this quantitative approach to PMI estimation for recently deceased individuals, but further work is needed. While the analysis only requires a small amount of tissue, has a user- friendly collection and analysis protocol, and is less subjective than visual methods, there is still significant research to be done prior to widespread applications as a PMI estimation method. Understanding variability in δ15N across decomposing muscle tissue groups, individual variation (i.e., muscle mass, disease, body chem-istry), and an accurate approximation for a perimortem δ15N value necessary to calculate Δ15N all need to be further researched prior to generation of a reliable regression formula and error rates.
Recipe for Identity
Authors: Mohanty Manisha , Satapathy Amrita
Published: July 2024

The placement of recipes in a food memoir serves the unique function of contextualising a life story against culture, tradition, and history. They serve as a form of self-expression that looks at life in its entirety through an amalgamation of the material and abstract aspects of existence. For women in the diaspora, recipes not only enable them to maintain a link to the homeland through the preservation and perpetuation of foodways but also serve as a medium to adapt to the new country. Bengali-American historian and writer Chitrita Banerji’s A Taste of My Life: A Memoir in Essays and Recipes (2021) is structured as a three-course meal and uses recipes to frame liminal moments of existence. The food memoir traces the arc of Banerji’s life over seven decades—from her childhood in India, to her student life in the US, followed by married life in Bangladesh and culminates with her mature years spent dividing her time between the US and India. Banerji reconstructs her life through the food that has defined her with the recipes providing a structure for her transnational life that spans years and continents; they provide unity and coherence across space and time. This paper argues that the inclusion of recipes helps Banerji in constructing an identity that takes the whole gamut of her experiences into account. The recipes show her journey from dislocation to relocation and provide the scaffolding for the construction of a self that is reconciled and empowered. Banerji’s recipes articulate the way in which food anchors her, provides the impetus for her growth and gives her the means to reflect on life with a certain resolve tempered with a hint of nostalgia. Through her narrative we see how a recipe borrows as well as adapts, preserves as well as modifies. There is replication as well as recreation in a recipe, which is similar to a diaspora individual balancing assimilation with adaptation. Every recipe reveals a new facet of her identity and is crucial in her understanding of the self in relation to others.
Dis/Connected in Diaspora
Authors: Natarajan Radhika
Published: July 2024

Reflecting on the nature of my ethnographic research comprising open-ended biographical narrative interviews and participant observation, this article explores what transpires between people who are socialized in broadly similar postcolonial, multilingual, and multireligious environments yet meet for the first time away from “home.” What do they share; what divides them? Where do their paths converge; where do they fork? How do they connect to each other; wherein lies the disconnect? “Home,” in this case, is the Indian subcontinent—India for me and Sri Lanka for my interlocutors—and the new location abroad is Germany. In the context of academic research, both my research subjects and I detected several commonalities and differences, some overt and unwittingly acknowledged, but most covert and left unsaid. I argue that the dissimilarities, the distance perceived, and the disjunct between the life-worlds, real or imagined, enabled my connection to different women from Sri Lanka. Aged between twenty and sixty, they had arrived through various modes as refugees, tourists, or marriage migrants from the 1980s onwards. Subsequently, they settled in Germany and saw themselves as a refugee community connected with fellow exiles across continents. Viewing the narratives and reflections of Tamil women refugees in terms of their diasporic memories and transnational citizenship, a distinction emerges between concrete, transient, and symbolic sites of memory with their own varying shades of gendering. This article takes up encounters with differentinterlocutors and illustrates the wide-ranging connections that materialized in the diaspora context. For the sake of narrative brevity, I shall focus on, firstly, the shared language, Tamil, with different vocabularies, secondly, the insights as a translator and facilitator, and thirdly, the nature of diasporic connections and memories across nation-states.
Racism Learnt and Unlearnt
Authors: Das Damayanti
Published: July 2024

For centuries, Africans migrated to India in different phases resulting in a significant presence of the African diaspora in this country. The term “African diaspora” gained currency only in the mid-nineteenth century in connection with the study of the people of African origin dispersed all over the world. But in countries like India, the African presence dates as far back as the period of the Indian Ocean slave trade. Historically, India and Africa have shared cordial political and economic relations. Their shared history of anti-colonial struggle, the mutual reverence for political leaders like Mahatma Gandhi and Nelson Mandela, and India’s support for postapartheid South Africa might indicate the peaceful coexistence of Indians and Africans in present-day India. But the on the ground reality hits differently, as depicted in “The Shade of You” by Anushree Majumdar, published in Eleven Ways to Love: Essays by Penguin India. Majumdar thinks herself a modern and enlightened woman until she gets into a relationship with Bryan Ochieng, a Kenyan studying in Delhi. As she gradually explores her relationship with Bryan, she comes to know about different aspects of racism that the African diaspora faces in Delhi in a more intimate way. Getting mocked and ridiculed for dating a black man in the public space makes her critique the racist attitude of her fellow Delhiites. She realizes that Indians have deeply internalized the colonial legacy of racism and colorism. She understands that, since our very childhood, we embrace a culture informed by racist ideology unconsciously. Indians are satisfied with the tokenist acceptance of black culture by celebrating black footballers and pop artists, but they would never let African diasporic people come closer as family and friends. This mindset has sufficiently exoticized and otherized Africans in India. Her proximity to Bryan reveals to her how ignorant she has been about Bryan’s culture despite her love of selective parts of Kenyan culture. The presence of Bryan and his Kenyan friends in her life offers her moments of self-reflexivity. She comes to question how much she has been able to unlearn her racial prejudices, and the answer forces her to confront an aspect of her race–intolerant subjectivity so far buried under her conscious race-sensitive self. Her self-realization makes her feel uncomfortable and apologetic. She feels that the self-realization that has dawned upon her is not enough to help her in the unlearning process overnight. She fails to maintain a long-term relationship with Bryan given their seemingly unbridgeable cultural gap at that point in time. But Bryan’s entry into her life marks the beginning of her anti-racism journey in the true sense of the term and it continues. Years later, she finds that she has become a better version of herself who is no longer troubled by the hidden guilt and shame associated with her relationship with an African.
Social Construction of the Ocean, Sea Power, and Maritime Transformation
Authors: Hou Kuang-hao
Published: July 2024

This review article elucidates concepts related to sea power, the social construction of the ocean, and maritime transformation. It begins with Mahan’s and Mackinder’s classic understanding of sea power, arguably the source of all traditional perspectives on the subject. Although this article accepts Till’s definition of sea power, it maintains that conventional wisdom does not offer a clear distinction between sea power as “a means of social power” and sea power as “states with powerful navies.” Furthermore, this article discusses Lambert’s conception of seapower identity, contending that his perspectives on seapower-state establishment are not based on relationships between the state, military, and the oceans. Lambert’s analysis of seapower states focuses on the activities that people engage in on land for seapower identity. His account suggests that maritime transformation could only occur in cases in which sea states transform into seapower states. However, this article claims that Steinberg’s concepts and theory of the social construction of the ocean provide a useful approach to examining the maritime transformation required for a transition from tellurocracy to thalassocracy.
Serving with Transgender Service Members
Authors: Dietert Michelle
Published: July 2024

Several studies focusing on public attitudes toward transgender people have been conducted, but there has been minimal research on how heteronormativity might influence military-affiliated respondents’ attitudes toward transgender service members. In this qualitative study, seven United States veterans participated in phone interviews from July 2020 to January 2021, in which they shared their thoughts about working with transgender service members. Findings also included their opinions regarding transgender service as it relates to unit cohesion, military effectiveness, and national security. Overall, this study uniquely contributes to the scholarly literature by providing a firsthand account of transgender military service from the service members themselves. The findings also lay the groundwork for future and more extensive studies related to the current integration of transgender service members as they workalongside their cisgender colleagues.

Published: July 2024

E-learning has been a main disruption in teaching and learning in the world, which has no doubt changed the narratives in the education sector. The advancements in the field of information and communication technologies have been a huge leap in the development of e-learning and presented a novel approach to education, with the switch from the conventional learning environment to transfer of knowledge online. During and after the COVID-19 pandemic it became imperative for more institutions of learning to adopt it. Despite the undeniable benefits of e-learning, usability has become the bane of its smooth implementation. This chapter highlights challenges associated with e-learning solutions and buttress the fact that usability will go a long way to give both teachers and learners a good user experience and give e-learning its pride of place in disruptive technologies. To successfully re-image education, more attention should be focused on ensuring usability of software solutions.
Surgical management of aortic dissection with aortic arch involvement
Authors: Pellegrini Giulio , Terzano Lorenzo , Luigi Stefàno Pier
Published: July 2024

The extent of aortic resection for aortic dissection is still debated. Although the resection and replacement of the aortic tract involved by the intimal tear remains the gold standard treatment, the fate and the evolution of the distal false lumen are hardly predictable. In recent years, several techniques and devices have been introduced to reduce the patency of the false lumen with consequent improvement of the positive remodeling of the true lumen, allowing the surgeon to perform a surgical strategy that is the most patient-tailored possible. This chapter aims to discuss hybrid strategies and new devices with related surgical techniques, with a brief literature review, to suggest a management protocol fitting each clinical and anatomical scenario.
Optimizing Initial Resuscitation: Clinical and Perfusion Parameters in Septic Shock
Authors: Yumoto Tetsuya
Published: July 2024

Blood lactate assessment is standard for diagnosing suspected sepsis, though its use for guiding therapy is supported by weak, low-quality evidence, as elevated levels do not always indicate tissue hypoperfusion. Trials of early goal-directed therapy focusing on central venous oxygen saturation have shown no benefit over standard care. Alternatives, ranging from physical examination markers like capillary refill time and mottling to objective parameters or biomarkers such as the veno-arterial carbon dioxide gap, near-infrared spectroscopy, and active renin, are emerging. Given the variability in effective perfusion markers, this section will summarize the evidence to better understand the role of lactate levels and identify which other markers are suitable for guiding initial resuscitation in septic shock.

Published: July 2024

The article highlights the absence of ESG criteria in financial education, risking economic, and ethical implications by neglecting future well-being. The bibliometric situation regarding financial education and ESG is assessed. Within this framework, the need to incorporate ESG factors in profitability evaluation is emphasized, particularly in adjusting discount rates to account for their impact. Moreover, it is possible to incorporate available data from Refinitiv to work with empirical material in academic processes. Including ESG variables in cash flow evaluation is crucial for comprehensive assessment. The article concludes by advocating for corporate governance standards that reflect the long-term sustainability impacts and the full integration of ESG factors into financial education.
Diabetic Macular Edema
Authors: Patelli Fabio , Lisa Carauni Ana , Rissotto Roberta , Chacra Lily , Laura Scopelliti Maria , M. Rossetti Luca
Published: July 2024

Diabetic macular edema (DME) is defined as the buildup of fluid within the retina in the extracellular space, specifically at the level of the macula in the inner nuclear, outer plexiform, Henle’s fiber layer, and subretinal space. Diabetes mellitus is one of the leading causes of visual impairment in industrialized countries and DME is the main reason for vision drop in diabetic patients. Several diagnostic methods are available for the characterization and staging of diabetic retinopathy (DR) and DME; the principal one for DME is optical coherence tomography (OCT), a quick and non-invasive technique that helps in decision-making for therapeutic choices based on biomarkers. Various classifications have been suggested over the years to aid in treatment management for DME. Current therapeutic options include laser photocoagulation, anti-VEGF (vascular endothelial growth factor) intravitreal injections or corticosteroids, and surgery. Recently, a surgical approach has been proposed with pars plana vitrectomy (PPV) in case vitreomacular traction is present together with DME. Refractory DME is a challenging scenario, and it may be managed by switching to a different class of intravitreal medications or with surgical intervention or micropulse laser. Future perspectives include artificial intelligence algorithms based on OCT and OCT-angiography images which may improve diagnosis and treatment of DME with better preservation of visual acuity in diabetic patients.
Removed: Dynamic Model History Matching and Testing in Petroleum Reservoir Simulation
Authors: Andino Saint Antonin Jose
Published: July 2024

When transition from static to dynamic reservoir modeling, historical field performance serves as a crucial benchmark. Unfortunately, freshly constructed geological models often fall short of accurately reproducing this historical behavior. To bridge this gap, the industry relies on a practice known as “history matching.” This chapter outlines essential principles of history matching, emphasizing not only the need to fit to historical data but also, more importantly, assessing the model’s ability to predict unseen data. A discussion on sources of error is followed by a review of classical history matching techniques, along with advanced methods available in modern software packages. Additionally, the chapter briefly explores neural networks as a potential avenue for improvement. It is important to recognize that history matching remains a challenge. As an inverse problem, it involves finding model parameters to align model responses with observed data. The under-determined nature of this problem adds complexity and is often compounded by data inconsistencies due to uncertainty or error. The chapter advocates viewing reservoir simulation not as a purely scientific endeavor but as a tool for informed business decision-making. Rather than aiming for exhaustive representation, models should focus on correctly forecasting critical characteristics relevant to field development decisions and reserves quantification.
Critical Image Detection (CiD) and Single Image Detail Analysis (SiDA) – A practical approach to AI in NDT
Authors: Topp Maximilian ,   Sentin GmbH, Nestler Dominik , Els Christian ,   Sentin GmbH,   Sentin GmbH
Published: July 2024

Artificial Intelligence (AI) is gaining momentum in consumer and business applications

and many approaches have changed the perspective on AI in Non-Destructive Testing

(NDT). Most current discussions about AI in NDT revolve around automated defect

detection / recognition (ADR), leaving the enormous potential of AI-based automation in

other areas of the inspector's work process unexplored. It is in the nature of NDT that

the human inspector's attention should be primarily focused on the parts that show

indications or defects. These usually make up only a fraction of the components to be

tested, as it is unknown which components actually show defects. This leads to a highly

inefficient process that requires an evaluation of all components and thus ties up massive

inspection capacities of human experts. The researchers of the German software company

sentin have developed a system to process critical findings first and present those to the

human inspector. NDT data such as images can be processed as batches leading to a

(pre-) sorted dataset considering various indicators such as potential defects, duplicates,

missing labels or references and many more. Such a resource-saving, high accuracy

Critical Image Detection (CiD) system allows evaluators to find anomalies in complex and

extensive datasets fast. After identification further automation can be achieved using a

Single Image Detail Analysis system (SiDA), which is more resource intensive, but gives

detailed information about the findings, potential defects and their location. The

integration of these systems holds significant promises for the future application of AI in

NDT. By streamlining the inspection process, they can generate substantial business value

through time and cost savings.

Authors: Sharova Tetiana , Voronov Volodymyr , Sharov Sergii , Kolomoiets Halyna , Voronova Anna
Published: July 2024

The study highlights the stages of organizing distance learning advanced training courses. It is a quantitative analysis of preschool teachers who have completed advanced training courses under the «Education Care» educational program. For this research, theoretical empirical methods and the quantitative analysis of statistical data were used. It has been revealed that preschool teachers are responsible for teaching children in preschool and must periodically improve their skills. Most advanced training courses in Ukraine are held in a distance format. The article describes the stages that need to be implemented to organize advanced training courses in a distance format. For the quantitative analysis, Google Forms were used, which contained information about the registered participants. The data for the period July-September 2023 was analyzed. It has been found that 13456 people (preschool educational institution principals, methodologists, preschool teachers) have completed advanced training courses on the "EducationCare" educational program in Ukraine within three months. Most advanced training course participants are preschool teachers (9498 participants), 71% of the total participants. Based on the results of the advanced training courses, 958 participants received certificates, which is 7% of the total number of participants in three months. We believe that a survey of preschool education staff who have completed advanced training on the "EducationCare" educational program is a prospective study.

Published: July 2024

Technology-enhanced assessment (TEA) means all types of assessments that use technological aid either online or offline, either during or after learning with the objective of improving or assessing the process of learning. Aims: This study assessed the effectiveness and influence of TEA on the academic performance of medical students in a Malaysian private university. A cross-sectional study was conducted and convenience sampling was applied to recruit participants. A validated online questionnaire was used and the participants were required to report their demographic characteristics, academic performance before and after using TEA, and their attitudes towards the TEA. Paired-t-test was performed to assess the difference in medical students’ mean CGPA before and after using TEA. Study findings showed that medical students have positive attitudes towards TEA and believe that TEA offers value to their learning. TEA was found to have a positive impact on the academic performance by which there is a significance difference in medical students’ mean CGPA before and after using TEA (p0.05). TEA is an effective tool that can enhance the learning process among medical students. Nevertheless, the sample studied need to be more diverse to be able to generalize the results for all medical students along different universities and countries.

Starting with a small group of enthusiastic school librarians, APISI now maintains hundreds of members nationwide and actively seeks opportunities to collaborate and partner with schools, businesses, government, not-for-profit organizations, etc. However, after seventeen years of serving school librarians in Indonesia, the APISI leader decided it was time for a change.
This article aims to help leadership teams in similar associations conduct change in their organization, especially those dealing with library and librarianship: the preparation for change and the steps to be taken.

Clickbait has been widely employed by news journalists as a strategy of viral journalism aimed at grabbing attention and generating high click-through rates. It is common for news journalists to imitate the tactics used by media influencers. However, the true cost of this practice remains unknown, especially in the context of journalism as a professional field, because clickbait is often associated with sensationalised headlines aimed at enticing readers. This research aims to examine the prevalence of clickbait practices as a form of viral journalism among journalists in Malaysia and investigate their impact on the media landscape. A qualitative approach was employed, involving interviews with 10 experienced journalists. The collected data was analysed using thematic analysis. Several themes emerged from the analysis: 1) Technological adaptation, 2) Shifts in Writing Style, 3) News Organisation’s Sustainability, and 4) Catering to Reader Demands. The findings reveal that journalists could not afford to ignore the trend as they would be unable to compete in the news market. It also shows that clickbait news is predominantly focused on soft news topics, amidst changing technology and reader interests. The study also reveals themes related to 1) Blurring boundaries between sensationalism and media ethics, and 2) News credibility and future news sense. The clickbait phenomenon has forced mainstream news outlets to pivot away from hard news coverage to maintain relevance. The emphasis on clickbait and entertainment-driven news may overshadow the importance of hard news, which typically covers significant events that provide a deeper understanding of the country’s current affairs. Nonetheless, some journalists emphasise the potential risks of excessive sensationalism, which can lead to misleading information as well as undermine the professionalism and credibility of journalism. This study underscores the importance of striking a balance between practising media ethics in writing and reporting news while remaining highly competitive in the online environment.

This study aims to investigate the influence of factors on the entrepreneurial intentions of students after graduation. This study conducted a survey of 388 students studying at universities in Hanoi (Vietnam) from January 2023 to March 2023. The PLS- SEM model is used to test the research hypotheses and proposed research model. Research results show that the Capital factor has the strongest influence on students’ intention to start a business after graduation, followed by Perceived behavioral control, then Attitude, Knowledge and experience. Subjective standards and finally the Entrepreneurship education factor. Based on the results of this analysis, relevant organizations such as ministries, departments, and universities can provide appropriate solutions to arouse and promote students’ entrepreneurial intentions after graduation.
The impact of market power on bank stability: Empirical evidence from Vietnam
Authors: Nguyễn Nhật Minh ,   Banking Academy of Vietnam, Trần Thị Phương Anh , Nguyễn Thị Minh Trang ,   National Economics University, Vietnam
Published: July 2024

This paper investigates the impact of market power on the stability of Vietnamese commercial banks using a quarterly unbalanced panel data set of 22 commercial banks in the period from Q2:2015 to Q3:2023, combined with panel data analysis models. Research results show that market power has a negative impact on the stability of Vietnamese commercial banks, implying that a more competitive banking market will have higher stability. In addition, a higher non-performing loan ratio, loan-to-deposit ratio and inflation also make banks less stable, as these factors increase bankruptcy risk, liquidity risk, and credit risk. On that basis, this paper proposes some policy recommendations to improve the stability of Vietnamese commercial banks, including creating a favorable banking business environment, encouraging diversification and innovation in the banking market (such as supporting small banks to increase capital or establish FinTech in a controlled manner). In addition, commercial banks need to proactively manage their internal factors such as credit risk and loan to deposit ratio to ensure stability.

Introduction: Dental implantation is a process of implanting dental implants into the bone of a patient, in places where one or more teeth are missing. For successful implantation, the process of osteointegration has to happen, which means that the dental implant placed in the bone should create a connection with it. The success of the osteointegration process depends on several factors, one of which is a biological modification of the material from which the implant is made. As a failure, it can occur during periimplantitis. Aim: The present study aimed to prove the influence of the foreign body on osteointegration during dental implantation, that is, the cause of peri-implantitis. The subject of our research was the analysis of new, sterile implants and their comparison with fallen, lost implants Materials and methods: For this scientific research we used a scanning electron microscope, which allows a detailed analysis of the implant surface. The analysis was performed on brand new, as well as on failed implants. A Scanning Electron Microscope (SEM) is a type of electron microscope that produces images of a sample by scanning its surface with a focused beam of electrons. Results: As a consequence of the deposition of many minerals (like Mg, and P), a higher wear resistance occurs on the implant surface. Traces of contaminant Na along with carbon, N, Ca, Al and O were also detected on the Ti surface of the failed implants, which are fallen implants. All these elements negatively affect the implantation success and are the cause of unsuccessful implant treatment. Conclusion: Dental implant contamination is a key factor for the success/failure of implantation. Traces of organic and inorganic contaminants can be found, despite the implant cleaning process and surface treatment of Ti, substances such as acid and sand.
