Development and Validation of the Online Antisocial Personality Scale (OAPS) Using the DSM-5 Criteria for Antisocial Personality Disorder (APD)
Authors: Griffiths Mark , Savci Mustafa , Savci Hale
Published: June 2024

Recent studies have consistently demonstrated that antisocial behaviors occur in online environments. Although online antisocial behavior has a long history, it appears to have become more widespread in recent years due to the widespread use of online social networks. Although there are established criteria and instruments assessing antisocial behavior there are few examining such behavior online. Therefore, the present study aimed to develop the Online Antisocial Personality Scale (OAPS). The OAPS was developed using the diagnostic criteria for antisocial personality disorder in DSM-5. The OAPS assesses antisocial behavior in online environments. The present study comprised 447 adolescents (219 girls and 228 boys) from four different samples. The measures used included the Online Antisocial Personality Scale (OAPS), E-Bullyıng Scale (E-BS), and Personality Belief Questionnaire-Short Form (PBQ-STF). The structural validity of OAPS was investigated with Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and criterion validity. When validity and reliability analysis of the OAPS are considered as a whole, it is concluded that the OAPS is a valid and reliable scale that assesses online antisocial personality among adolescents.

Authors: Citir Aysun Guven , Toros Serkan , Ozturk Fahrettin
Published: June 2024

In this study, the delamination resistance of carbon fiber reinforced polymers (CFRP) consolidated with titanium alloy at the interface between the metal and composite was investigated experimentally and numerically. End-notched flexure (ENF) tests were performed to assess the fracture toughness (GIIC) for Mode II crack expansion of Ti6Al4V titanium alloy/CFRP composite parts. The EFN test is applied to Ti6Al4V-carbon fiber/low melt poly (aryl ether ketone) (CF/LM-PAEK) and Ti6Al4V-carbon fiber/poly (ether ketone ketone) (CF/PEKK) composites with the [0°]24 stacking sequence of unidirectional (UD) fibers. Experimental results indicate that the LM-PAEK composites exhibited Mode II strain energy release rate values 27.64 % higher than those of the PEKK composites. The finite element simulation by LS‐DYNA shows good correlations with the experimental results, with an average error of 5.44 % for the PEKK and 10.58 % for the LM-PAEK, respectively.

Published: June 2024

Concrete is the most significant source of construction in the construction industry of the world. However, concrete causes excessive production of cement, which is one of the key contributors of carbon dioxide emissions to the environment. To minimize the use of cement in concrete, various innovative materials are being added in concrete to make it sustainable. In this study, a comparative study between three fibers Carbon Fiber, Glass Fiber, and steel fibers was done to determine which one is the most suitable fiber. For this purpose, testing on specimens was done for tensile and compressive strength at 0.5% addition of each fiber. Testing was done after 3, 7, 14, and 28 days of curing. The results spelled out that the highest compressive strength of 37.53 MPa of cube specimens was found in carbon fiber after 28 days, and Glass fibers exhibited the lowest gain in strength at about 32.335 MPa. Carbon Fiber gained 28% more strength than the control mix. On the other hand, tensile strength was also found highest in carbon fibers i.e. for the cubes the maximum difference between different fibers inducted concrete samples is 28% approximately, and for cylinders it is 27%, respectively. On the other hand, the highest tensile strength of concrete was also gained with the carbon fiber at about 3.61 MPa. The same was found lowest in glass fiber at 3.12 MPa. Carbon fiber got about 44 % improvements in tensile strength.
Dual boundary element method for comparative studies on fatigue crack growth models
Authors: Mantilla Jairo A , Martínez Manuel , Villegas Diego F , Bohorquez Oscar , Díaz Jorge G.
Published: June 2024

Fatigue crack growth studies require models that accurately predict component life with low uncertainty. Despite the large number of proposed models, there is no clarity on their applicability, which justifies a comparative analysis between some of them. The dual boundary element method (DBEM) was applied for cracked bodies, whereby the stress intensity factors (SIF), the growth rate, and the number of cycles were computed. Three crack increment models were studied under constant amplitude fatigue loads: the Paris, the Klesnil-Lucas, and the Forman models. Results were validated with experimental literature and through the finite element method, indicating that each model represents a specific zone of the crack growth curve. Klesnil-Lucas model reproduces the region near the fracture threshold, Paris fits the controlled crack growth zone, whereas Forman’s model recreates the unstable fracture zone, i.e., when the stress intensity factor approaches the material’s fracture toughness. The J-integral with stress field decomposition gave errors below 0.8% for mode I. Results were similar for the propagation path and the number of cycles to those obtained with the finite element method, with errors of about 3% considering different K-effective approaches. Klesnil-Lucas accurately predicts the number of cycles with an error margin below 3%, considering the curved region in the growth rate at the propagation onset, while the Paris model becomes very conservative, predicting values up to 50% lower than experimental data. The Klesnil-Lukas model is advised for simulating the entire crack propagation.

Published: June 2024

Adhesive joints play a vital role in different industries owing to their advantages and ease of application compared to other joining methods. This research focuses on enhancing the mechanical properties of epoxy adhesives by incorporating graphene nanoplatelets (G) and iron-oxide nanofillers (Fe3O4). Single-lap adhesive joints, including both G and Fe3O4 nanoparticles, are fabricated at 2%, 3%, and 4% weight percentages and tested under tensile load at ambient, 45°C, and 88°C. The results reveal that adding G and Fe3O4 nanofillers enhances shear strength at elevated and room temperatures without altering the epoxy glass transition temperature (Tg). Furthermore, G nanofiller performs better in improving shear strength than Fe3O4. The optimal weight percentage is identified as 3 wt% for G and Fe3O4, as higher percentages lead to decreased shear strength due to agglomerations. This study provides insight into tailoring epoxy adhesives for improved mechanical performance under varying temperature conditions.

Pancreatic cancer, often described as the most devastating among cancers, characterized by a malignant tumor with a grim prognosis and a limited response to systemic therapy. Its characterization is common in old age and very rare and unusual in the young age. We present an unusual case of a male patient, 35 years old. A case of diabetes and of pancreatic cancer in the head of the pancreas with stomach and bone metastases, highlighting its diagnostic challenges and management. The patient presented with changed bowel habits for a month, generalized body aches for a week, hip joint pain with decreased mobility for a week, decreased oral intake for three to four days, and hematuria for two days. The patient complained of irregular bowel habits, which included fatty and oily feces, minor abdominal discomfort, and intermittent constipation. According to the patient, he developed generalized bone pain in upper as well as lower back unlike usually present in pancreatic cancer. A contrast-enhanced CT scan of the abdomen and pelvis revealed indications of a heterogeneously enhancing lesion in the pancreatic head, with an interior necrotic component measuring 32x31 mm and generating a substantial dilatation of the pancreatic duct and CBD. A tentative diagnosis of pancreatic cancer in the head of the pancreas with stomach and bone metastases was made based on clinical history and testing. Given the poor prognosis associated with pancreatic cancer patients, the patient was admitted for conservative and palliative care. This case emphasizes the rarity of pancreatic cancer in young patients and that further research is needed to understand its epidemiology and etiology.

Published: June 2024

The halal food control system is one of the critical aspects that need attention in sustaining the Malaysian halal industry. In practice, the existing halal food control system involves the roles of several stakeholders and is implemented independently according to their respective jurisdictions. No integrated control mechanism coordinates the roles of all stakeholders, thus resulting in fraud cases to easily happen in the industry. To effectively coordinate these roles, an integrated halal food control system must be developed. Therefore, this concept paper aims to discuss the roles of stakeholders involved in the halal food control system and to propose a conceptual halal food stakeholder control system model based on the objectives of the Islamic law framework. Information for this paper is gathered based on a literature review of previous studies related to the halal food control system. The conceptual model is expected to be a reference and guideline for all stakeholders involved and will serve as a theoretical foundation for future research in this area. Additionally, it can enhance consumer trust in Malaysia’s halal certification and support the country’s goal of becoming a leader in the global halal food industry.

Objective: There is limited data on the effect of post-COVID-19 syndrome on functional outcomes compared with healthy uninfected individuals. This study aimed to compare the muscle function, exercise capacity, and quality of life of patients with post-COVID-19 syndrome with that of healthy controls.
Method: Twenty patients with post-COVID-19 syndrome and twenty healthy controls participated in the study. The Incremental Shuttle Walk Test (ISWT) was used to measure exercise capacity, and the Timed Up and Go Test (TUG) was used to assess functional balance. Quadriceps muscle strength (QMS) and handgrip strength (HGS) were measured. Assessment tools included the McGill Pain Questionnaire (SF-MPQ) for pain, the Tampa Scale for Kinesiophobia (TSK) for movement fear, the Modified Medical Research Council Dyspnea Scale (mMRC) for dyspnea, the Fatigue Severity Scale (FSS) for fatigue perception, and the Cognitive Failures Questionnaire (CFQ) for cognitive status.
Results: The mMRC dyspnea, TSK, FSS, SF-MPQ total scores, and pain severity of patients with post-COVID-19 syndrome were higher than those of healthy controls (p<.05). Compared to the healthy group, the ISWT and %ISWT distances were significantly lower in the post-COVID-19 group (p<.05).
Conclusion: Exercise capacity is negatively affected; anxiety, pain, fatigue severity, dyspnea, and kinesiophobia levels are increased in patients with post-COVID-19 syndrome compared with healthy groups. However, muscle strength, balance, and cognitive function are preserved in individuals with mild-to-moderate COVID-19 infection. Pulmonary rehabilitation programs should be designed on the basis of these multiple influences with a multidisciplinary approach in the long-term rehabilitation of individuals with COVID-19 infection.

Pine Marten
Authors: Bagur Dan
Published: June 2024

Offering new insights into how they grow, learn and live, this book delves deep into the secretive behaviour of one of our rarest and most elusive mammals. It covers Pine Marten social interactions, courtship, mating, nesting and kit rearing, feeding and diet, as well as relationships with other wildlife. It also examines the considerable advantages of having these animals around and why it is in our interest to help them. Pine Martens are slowly starting to increase their numbers and expand their range in Britain and Ireland as conservation efforts help them recover. There are now more sightings, while interest in what these animals do and why is greater than ever. This book uniquely uses photography to show (not tell) the reader all aspects of Pine Marten behaviour – uncovering these mammals’ private life and shining light into the darkness of the night. The candid images allow the reader to experience this magnificent animal close up as never before. Aimed at amateur naturalists and experts alike, this groundbreaking book provides fascinating observations and a wealth of information.
European Deserts
Authors: Stone Chris
Published: June 2024

This is the untold story of the deserts of Europe. Scattered across the lowlands of this green subcontinent, these sandy, arid and infertile wildernesses are ‘cold deserts’. In existence for millennia and formerly much more extensive, today they present landscapes profoundly different from their surroundings and offer refuge for scarce flora and fauna with nowhere else to go. Fascinating and often magical, though frequently largely barren – or apparently so – they provide a rare glimpse of our planet in its raw form, a collective object lesson about the impact of humanity upon the natural environment. Individual chapters cover sites in Spain, France, the Netherlands, Britain, Romania, Germany, Poland and Iceland, many of the places in question being remote and unknown to many. The specialised wildlife of these badlands and heathlands is integral to their unique character, from the great bustard and the stone-curlew to the adder and tiger beetle, from juniper to Corsican pine. Invisible in plain sight and often under threat, few recognise or value Europe’s deserts as the relict environments that they are. Unknown, uninhabited and seldom regarded as places of beauty, our knowledge of their origins and the roles that these ‘wastelands’ once played in economies and societies is remarkably scant. Frequently poverty-stricken regions, many had reputations as undesirable and even dangerous places. Vast expanses of these unique habitats have been ‘reclaimed’ for farming and forestry. This groundbreaking book reveals their remnant wonders and makes an indisputable case that any remaining fragments must be preserved and treasured.

Sustainable Business Practices for Biodiversity: Leveraging Landscape Approaches
Authors: Nishi Maiko , Subramanian Suneetha M. , Varghese Philip
Published: June 2024

Drawing from first-hand experiences managing productive landscapes and seascapes, this brief provides insights on how landscape approaches can promote biodiversity-friendly business through local stewardship, cross-level collaboration and peer learning. Landscape approaches are collaborative strategies that promote biodiversity-friendly business practices. These approaches involve diverse stakeholders, such as local communities and other actors along the value chain, working together at a landscape or seascape scale. Leveraging landscape approaches to advance sustainable business practices for biodiversity is an iterative process, involving adaptation and course correction to accommodate diverse needs and interests among stakeholders. This enhances collaboration across and beyond a value chain. These approaches also capitalize on traditional knowledge, which has been embodied through augmenting local experiences and wisdom to help integrate different knowledge systems that are complementary, creating new business opportunities for biodiversity-friendly innovation. Recommendations: (i) Bolster local stewardship to build and pursue a common vision with enhanced recognition of the livelihood and business values of biodiversity; (ii) Institutionalize a participatory approach to cross-level collaboration that incorporates review and monitoring and capacity development elements; and (iii) Promote biodiversity elements in education and peer-learning to mainstream biodiversity in business in alignment with global policy goals for sustainability.
Analysis of Even Pricing in Real Estate Markets: Different Asset Types and Implications
Authors: Morali Orcun , Yilmaz Neslihan
Published: June 2024

This study examines price clustering in different real estate markets. Using a novel data set, we document that prices are clustered around even figures, and exact prices are not common in the residential, commercial and land markets. Prices increase in multiples of five hundred, five thousand or fifty thousand depending on the market, and particular digits can predict the prices. The magnitude of even pricing is comparable to months’ worth of disposable income and has potential implications on the financial well-being of the market participants.
Purchase Intention of Apartments in a Metropolitan Area in Vietnam: The Mediating Role of Attitude Toward Behavior
Authors: Pham Dinh Han , Vo Thanh Hai , Dao The Son , Le Mai Trang , Nguyen Ngoc Diep
Published: June 2024

This study aims to investigate the intention to purchase an apartment to better understand the actual situation of the real estate market in the metropolis areas of Vietnam, like Ho Chi Minh City. Eight constructs are identified based on extending the theory of planned behavior (TPB), and eight hypotheses are proposed. A questionnaire is conducted with buyers of apartments which provided a total of 517 responses for a data analysis with the structural equation model in Bloemer and Kasper (1995), and used to validate the proposed hypotheses. Attitude toward behavior (ATB) is found to be the most important determinant, followed by subjective norms and perceived behavioral control. In addition, project facilities, location, environmental issues, and price and credit have positive effects on ATB and indirect effects on behavioral intention through ATB. Meanwhile, the relationship between physical quality and ATB is insignificant. Thus, ATB plays an important role in enhancing the purchase intention of buyers of apartments at this stage. The findings of the study have valuable implications for the government and real estate developers in order to meet consumer demand. Besides, the competitiveness and sustainability of the real estate industry in Vietnam might be enhanced through practical activities.

Published: June 2024

The human resources (HR) department is among the most human-centric departments in every organization, primarily focusing on supporting and developing the workforce that ensures long-term growth and viability of businesses. This is why HR is a key area where data is particularly valuable. Data is an integral part of the HR landscape. Its data repository captures the dynamics of the organization’s people and their workplace interactions. HR data can help organizations uncover more effective strategies for team management, enhance overall company performance, and yield improved business results, especially during times marked by uncertainty and change. A 2022 report by Harvard Business Review Analytic Services found that progressive organizations utilize people data beyond the HR department, and they often combine this people data with business data to deliver critical insights to their decision-makers.
