ABSTRACT Dropstones in lacustrine and marine sediments show a wide range of sizes: from less than a millimeter to many meters. Their size and shape determine the velocity and the acceleration when they settle through the water column, and this, in turn, determines in principle the imprint that they make in the bottom sediment. Although these parameters are crucial for dropstone deposition, the unknown material (sediment) properties (like strength, porosity, pore-water content, viscosity, etc.) of the bottom sediment play a just as important role in this process as the water depth, which can physically be understood as the length of the pathway traveled vertically through a dense medium before the impact. Reconstruction of the principal environmental conditions at the time of dropstone fall and deposition consequently requires considering the variety of factors affecting the final imprint depth of a dropstone, the combination of several numerical methods. Here, we show the results of numerical modeling of dropstones with different sizes that settle through water columns with different depths. Our results show how environmental factors control the deformation structures formed at the sedimentary surface during the impact of a dropstone, and how deep the imprint caused by the settling dropstone will be.

Current research shows that the only hazardous air pollutant of significance emitted from large bore natural gas engines is formaldehyde CH2O. A literature review on formaldehyde formation is presented focusing on the interpretation of published test data and its applicability to large bore natural gas engines. The relationship of formaldehyde emissions to that of other pollutants is described. Formaldehyde is seen to have a strong correlation to total hydrocarbon (THC) level in the exhaust. It is observed that the ratio of formaldehyde to THC concentration is roughly 1.0–2.5 percent for a very wide range of large bore engines and operating conditions. The impact of engine operating parameters, load, rpm, spark timing, and equivalence ratio, on formaldehyde emissions is also evaluated. [S0742-4795(00)01004-8]

AbstractAtopic dermatitis (AD) is a common chronic inflammatory skin condition which impacts psychological wellbeing and social relationships. There have been studies of AD’s impact on quality of life (QoL) in Western countries, but these findings cannot be directly extrapolated to Asian populations with genetic, environmental and cultural differences. Therefore, we aimed to systematically review the literature pertaining to QoL impairment in AD in East and Southeast Asia to characterize the impact of AD on patients and their families, and to identify the factors affecting the degree of QoL impairment. A search of English language papers was conducted on MEDLINE, EMBASE, PSYCInfo, Global Health and Web of Science. Observational studies measuring QoL using single or multi-item instruments in people with self-reported or physician diagnosed atopic dermatitis were included. 27 studies from 29 articles were included and synthesized. There is data documenting QoL impairment in AD sufferers and their families, across a wide range of Asian countries, healthcare settings and ages. Aspects of QoL impacted to a greater extent included symptoms of itch, feelings of embarrassment, and sleep disturbance. Severity of disease affects the degree of impairment of QoL, but there is no apparent link between QoL impairment and patient demographic factors, or other medical factors such as age at diagnosis or duration of illness. Our findings also highlighted the need for clinicians to actively explore the impact of patient’s symptoms, especially in an Asian context where healthcare communications are traditionally doctor-centric.

An issue of Sustainable Environmental Development has occupied a wide range of interests of researchers and economists in some developing countries. The environmental issues are tightly linked to the development policies and the environmental grasp is no longer a matter of social welfare, but rather is a matter of economical; social and human dimensions. The research displays a concept of sustainable development, then estimating the impact of two variables: the economic development and the bio-ecological system on the sustainable development of some countries, including Iraq according to the fact that “increasing demand for foods and products in these countries has led them towards the intensive usage of natural resources which has, eventually, impairs the rates of development and contributes in the deterioration of bio-ecological system and impairs the sustainable development. The results of the analysis showed that the environmental ecosystem variable has a greater impact on sustainable environmental development than the economic development variable, which means that the environmental situation of some countries, especially the developing countries, continue to deteriorate, requiring all specialists and governments to make efforts to preserve the ecosystem for future generations.

BACKGROUND Although personal health devices (for example, smartwatches, fitness trackers and intelligent bracelets) offer great potential to monitor personal fitness and health parameters, many users discontinue using them after a few months. Thus, it is critical to study the postadoption behaviors of current users to enhance their engagement with personal health devices and use behaviors. However, there is little empirical research on the factors affecting users’ engagement in beneficial use behaviors. Mindfulness and identity are not new topics, but the applications of these concepts in the field of information systems are emerging themes. Information technology (IT) mindfulness has been conceptualized in previous studies; however, little is known about the antecedents and consequences of IT mindfulness in the mobile health (mHealth) context. OBJECTIVE The main aim of this study is to explore both IT identity and IT mindfulness to develop a new ground for research in the domain of mHealth postadoption. Thus, we aim to explain why users should be fully mindful of their engagement with PHDs and what could be the consequences and implications. METHODS This study proposes that IT mindfulness can play an important role in improving the use behaviors of users. Through a web-based survey with 450 current users of a personal health device, this paper tests the relationship between IT identity and IT mindfulness in the postadoption stage of using personal health devices. RESULTS We found that IT identity significantly shapes IT mindfulness associated with PHDs. Moreover, the IT identity–IT mindfulness relationship is negatively moderated by individuals’ perceived health status (<i>P</i>=.003). Finally, the results of this study show that IT mindfulness can significantly predict automatic use behaviors (eg, continued intention to use), active use behaviors (eg, feature use and enhanced use behaviors), and commitment behaviors in using personal health devices (eg, positive word-of-mouth intention). CONCLUSIONS The findings of this study provide implications for both research and practice. This study can contribute to our current understanding of IT mindfulness by developing and empirically testing a research model that explains the determinants and outcomes of the IT mindfulness construct in the context of personal health devices. The results imply that IT mindfulness significantly helps individuals express their alertness, awareness, openness, and orientation in the present in their postadoption interactions with smart devices used for health care purposes. Finally, our findings may assist practitioners and IT developers in designing mindfulness-supporting PHDs. Owing to the impact of IT mindfulness on postadoption behaviors, its 4 dimensions could be used for developing PHD technologies. Moreover, PHD developers may need to direct their efforts toward increasing IT mindfulness by reinforcing IT identity to serve and retain a wide range of target users.

Purpose Resistance to change (RtC) is widely recognized as the main reason of failure, when it comes to change initiatives. Despite its importance, there is still a rather limited knowledge concerning the factors that trigger this behavior at the workplace. The purpose of this paper is to identify the factors affecting RtC in healthcare organizations (namely, hospitals) and specifically, in emergency departments (EDs). Design/methodology/approach An original conceptual framework (research model) has been developed and empirically tested using primary data collected from EDs of six Greek hospitals. In total, the actual sample incorporates the responses of 158 ED health professionals who completed a structured questionnaire. Findings The findings verified the initial assumption that “disposition towards change (DtC),” “anticipated impact of change (AIC)” and “attitude towards change (AtC)” mediate the impact of various personal and behavioral characteristics on “RtC.” The results suggested that “RtC” is (indirectly) influenced by four main factors (“employee-management relationship,” “personality traits,” “employee participation in the decision-making process” and “job security”). Originality/value This study investigates how several factors affect, both directly or indirectly, employee reactions toward “RtC.” It also examines the mediating effect of three factors (“DtC,” “AtC,” “AIC”) that capture three different dimensions of individual evaluation toward change, something that goes beyond previous work. In addition, the present study examines a wide range of antecedents of RtC, including both personality-related and job-related factors.

The article deals with individual professional diseases of builders and the factors that influence their occurrence and development. The author believes that a wide range of industrial activities of representatives of the construction professions and the impact of the environment plays a vital role in the development and progression of most occupational diseases. However, the harmful effects of these diseases on the body are greatly underestimated, which reduces the effectiveness of preventive measures and complicates treatment. It is also impossible to ignore the occupational diseases of drivers of construction vehicles. The most common of them are diseases associated with the development of cardiovascular pathology, neuropsychiatric disorders, gastrointestinal disorders, diseases associated with problems with the musculoskeletal system, disorders caused by a sedentary lifestyle, as well as allergic and oncological diseases. In addition, drivers are affected by harmful sanitary and hygienic factors: noise, vibration, high temperature, harmful impurities in the bus cabin, nervous tension. Taking into account all the above factors, it is necessary to carry out appropriate prevention of occupational diseases of representatives of construction specialties by conducting educational work and conducting regular medical examinations.

 The progress of this study is to offer and test models that include models of leadership of customer behavior and willingness to deliberately purchase luxury fashion items. The impact of many social, psychological and social emergencies has been identified and recognized. To narrow this gap, the study was conducted to identify key milestones in the readiness to buy counterfeit products in Pakistan. The survey was conducted by 257 people from three major markets in Pakistan, such as Lahore, Faisalabad and Islamabad. In addition, the SEM technique is used to test the hypothesis. The study ends with some contributions and findings. Economic benefits, past experience and materialism of counterfeiting play an important role in the pursuit of counterfeit products. While the hedonic benefits were not as important as hypothetical. The study identifies the leading determinants of lying and willingness to buy fake products by testing a wide range of literature and theories on consumer behavior and marketing. From the point of view of managers, stylish fashion makers will gain insight into the factors that play a key role in counterfeiting. However, a little of this study was revised on the basis of the regional context. From a theoretical point of view the theoretical theory is encouraged to enter into the literary literature relating to purchasing decisions.
