On the Solutions of a Third Order Rational Difference Equation

Difference equations, although their forms look very simple, it is extremely difficult to understand thoroughly the global behaviors of their solutions. One can refer to [1–9] and the references therein. Difference equations have always played an important role in the construction and analysis of mathematical models of biology, ecology, physics, economic processes, etc. The study of nonlinear rational difference equations of higher order is of paramount importance, since we still know so little about such equations. In [10], M. Aloqeili has discussed the stability properties and semicycle behavior of the solutions of the difference equation
DECOMPOSING DEFINITENESS IN VIETNAMESE

This paper provides a detailed description of how Vietnamese encodes definiteness in the nominal phrase in the context of the crosslinguistic debate about the existence of lexical articles in classifier languages. We first show that so-called lexical determiners in Vietnamese are not genuine articles in the technical sense. We then scrutinize six different referring expressions in Vietnamese including bare nouns, classifier – nouns, numeral – classifier – nouns, plural – classifier – nouns, focus cái – classifier – nouns while pointing out how Vietnamese differs from other better-studied classifier languages. Based on this thorough investigation, we posit that Vietnamese systematically differentiates six levels of the givenness hierarchy in the sense of Gundel et al. (1993); therefore, Vietnamese contributes to a better understanding of the nature of definiteness and the structure of the nominal phrase.
Feasible Point Pursuit and Successive Convex Approximation for Transmit Power Minimization in SWIPT-Multigroup Multicasting Systems

We consider three wireless multi-group (MG) multicasting (MC) systems capable of handling heterogeneous user types viz., information decoding (ID) specific users with conventional receiver architectures, energy harvesting (EH) only users with non-linear EH module, and users with joint ID and EH capabilities having separate units for the two operations, respectively. Each user is categorized under unique group(s), which can be of MC type specifically meant for ID users, and/or an energy group consisting of EH explicit users. The joint ID and EH users are a part of both EH group and single MC group. We formulate an optimization problem to minimize the total transmit power with optimal precoder designs for the three aforementioned scenarios, under certain quality-of-service constraints. The problem may be adapted to the well-known semi-definite program and solved via relaxation of rank-1 constraint. However, this process leads to performance degradation in some cases, which increases with the rank of solution obtained from the relaxed problem. Hence, we develop a novel technique motivated by the feasible-point pursuit successive convex approximation method in order to address the rank-related issue. The benefits of proposed method are illustrated under various operating conditions and parameter values, with comparison between the three above-mentioned scenarios.
Parenting Stress among Parents of Children with Autism Spectrum Disorder: The Need of Stress Management Guidelines and Policy

This concept paper reviews the issue of parenting stress in mothers and fathers of children with Autism Spectrum Disorder (ASD), and highlights the need for stress management guideline and policy for these parents in Malaysia. Many studies have shown that parents of children with ASD are experiencing a high level of stress. Despite this issue, there has not been any local measures to improve the well-being of the parents. In Malaysia, there is no policy or standard guideline for parents of children with ASD, hence maintaining the risk of mental health cases among them. In order to overcome this issue, this paper reviewed the Lazarus and Folkman’s (1984) problem-focused strategies used by parents of children with ASD from previous studies. The strategies mentioned in this paper had been empirically proven as reducing the parents’ stress level. This paper also recommends the strategies to be included in a local policy to help the parents manage their stress.
Representing a Model to Measure Absorbency of Information Technology in Small and Medium Sized Enterprises

With rapid development of information technology (IT) and further deepening of informationization construction, more and more enterprises have realized the strategic value of IT and made great investments in it. However, during the IT implementation process, decision-making, adaptation degree, and IT performance are often inferior to the anticipation. The assimilation of technology can be defined by the extent to which the use of Information technology spreads across organizational processes and becomes routinized in activities. Capabilities of information technology play crucial role in an ever-changing environment and are considered as one of the most important sources for enterprises while enterprises should acquire some effective capabilities so that they can effectively deploy and utilize information technology. But companies need to increase their Absorbency of IT to accept it for effective use of IT, since the acquisition and use of information technology is simply not feasible and any information technology does not create value. The purpose of this investigation is to represent a model to measure absorbency of information technology in small and medium-sized enterprises. To do so, dimensions of the "absorbency of information technology" was determined through exploratory factor analysis in a survey research and confirmatory factor analysis was used to confirm model validity. Findings show that three dimensions are related to absorbency of information technology including the capability for innovative technology, Inside-Out IT capability and IT management capability, among which the capability for innovative technology has the highest correlation with the concept of absorbency of information technology.
Role of Eddy Diffusion in the Delayed Ionospheric Response to
Solar Flux Changes

Abstract. Simulations of the ionospheric response to solar flux changes driven by the twenty-seven days solar rotation have been performed using the global 3-D Coupled Thermosphere/Ionosphere Plasmasphere electrodynamics (CTIPe) physics- based numerical model. Using the F10.7 index as a proxy for solar EUV variations in the model, the ionospheric delay at the solar rotation period is well reproduced and amounts to about 1 day, which is consistent with satellite and in-situ measurements. From mechanistic CTIPe studies with reduced and increased eddy diffusion, we conclude that the eddy diffusion is a primary factor that influences the delay of the ionospheric total electron content (TEC). We observed the peak response time of atomic oxygen to the molecular nitrogen ratio to solar EUV flux changes quickly during the increased eddy diffusion compared with weaker eddy diffusion. These results suggest that an increase in the eddy diffusion leads to faster transport processes and an increased loss rates resulting in a decrease of the ionospheric time delay. Furthermore, we found that an increase in solar activity leads to an enhanced ionospheric delay. At low latitudes, the influence of solar activity is stronger, as EUV radiation drives ionization processes that lead to composition changes. Hence, the combined effect of eddy diffusion and solar activity lead to longer delay in the low and mid latitude region.

The data analysis techniques were descriptive qualitative and quantitative. The result of this research was a derivative learning media in the form of videos presented through Instagram. The feasibility test results showed that the learning media had met three eligibility criteria for learning media. The assessment of media and material experts showed that learning-based Instagram media was in the good category. Based on students' assessment, learning media's feasibility based on Instagram social media was good to use. The correlation between the students response questionnaire and the learning outcome test also showed a unidirectional and significant correlation. It indicated that there was a correspondence between the questionnaire scores and the learning outcome test scores. Based on these results, learning media through Instagram social media is suitable for the learning process.
Epidemiologic aspects and risk factors associated with infertility in women undergoing assisted reproductive technology (ART) in north of Iran

Objective: This study aimed to investigating of the epidemiological aspects of infertility and related risk factors in infertile women. Materials and methods: This cross-sectional study, carried out on 330 infertile women referred to two infertility treatment center of Imam Khomeini Hospital and Mother center in Sari, Iran, from April 2015 to March 2017. Results: 54.5% of these women were in the age of 30-39 years, infertility duration in 55.2% was 1-5 years, Body mass index (BMI) in 44.5% of samples was 2630 kg/m2, 54.5% had diploma and associate degree. 63.6% lived in urban areas. 74.5 % of patients reported primary infertility. History of polycystic ovarian syndrome (PCOs) and pelvic infl ammatory disease (PID) and poor ovarian reserve were the most common causes and risk factors for the infertility with prevalence 19.42%, 16.81% and 13.91%, respectively. Most underlying disease was thyroid disorders (54.5%). There was found statistically signifi cant relationship between residents of urban areas and infertility duration, endometriosis and educational levels, miscarriage with thyroid. Data analysis performed using IBM SPSS 21 software and Chi-Square test (p < 0.05). Conclusion: The results showed that women with infertility in north of Iran were more likely to be older, less educated, and also had overweight. They are more possible to have ovarian disorders. In these area, thyroid disease more common like Iodine defi cient regions. Future research should be focused on the reasons why majority of women don’t seek treatment for the underline signifi cant diseases that may be eff ects on ovarian function and fertility.

Inhibition of cyclooxygenase activity by diclofenac attenuates varicose remodeling of mouse veins

Aim: The development of varicose veins is driven by risk factors that support the progression of venous hypertension, specifically, by chronically augmenting the circumferential tension of the venous wall. We have previously verified the relevance of this biomechanical stimulus for the activation of venous cells and the structural remodeling of the vein wall. Recent transcriptome analyses revealed an increase in the expression of the gene encoding prostaglandin-endoperoxide synthase 2 [cyclooxygenase 2 (COX-2)] in biomechanically stressed human vein endothelial cells. This observation prompted us to investigate the functional relevance of COX activity for the onset of pressure-induced venous remodeling. Methods: For the in vitro experiments, isolated mouse veins were exposed to elevated intraluminal pressure levels to study the markers of cellular activation. For the in vivo experiments, pressure-dependent varicose remodeling of veins was induced by ligation of an efferent vein in the mouse auricle. Diclofenac was applied to inhibit the activity
Achieving drought resilience in the grazing lands of northern Australia: preparing, responding and recovering

Northern Australia is characterised by high rainfall variability and extended droughts that challenge sustainable and profitable management of grazing properties. To achieve drought resilience, emphasis must be placed on supporting livestock managers to prepare for drought as well as implementing appropriate drought response and recovery actions. Here we describe insights and learnings gained from working with scientists, industry development and extension officers, and property managers, to enable more profitable and drought resilient extensive livestock production systems across northern Australia. We provide examples from the modelling and analysis of hypothetical grazing properties representative of enterprises across northern Australia. To prepare for drought, we principally propose the application of the farm-management economics framework to identify investment strategies which can improve enterprise resilience through building wealth over the longer term. The critical first step in drought preparedness for beef businesses was the implementation of management strategies to achieve the optimal herd structure, steer sale age, and breeder body condition. Other key strategies to improve profitability across northern Australia were (1) addressing a phosphorus deficiency for cattle through effective supplementation and (2) establishing adapted perennial legume-grass pastures to improve steer nutrition. In addition, we identify the benefits of working closely with livestock managers and industry to gain adoption of proven technologies that effectively improve decision-making capacity and the drought preparedness of extensive livestock production systems. The usefulness of the farm-management economics approach to assess the relative value of alternative tactical destocking and restocking decisions during drought response and recovery is also discussed. These latter analyses can highlight important differences between options in terms of future profit and cash flow, as well as the ability to rapidly return the property to the most profitable herd structure and age of turnoff, with consideration of production and financial risk. Additionally, integrating pasture growth models with herd or flock economic models can provide insights into the effects, on profitability and sustainability, of alternative destocking and later restocking strategies over the longer term. Combined, the farm-management economics framework approach can support more informed decision-making by livestock producers and hence enable more profitable and drought resilient extensive livestock production systems. However, achieving drought resilience in the grazing lands of northern Australia will require emphasis on drought preparation, in addition to appropriate action in response and recovery phases of drought. Key to this approach is increasing the adoption of strategies that enhance drought preparedness.
Effect of lignin on the co-pyrolysis of sludge and cellulose

ABSTRACT In order to investigate the role of the lignin in the co-pyrolysis process of the sludge and the cellulose, the co-pyrolysis process was carried out in a thermogravimetry analyzer. The result shows that when the proportion of the sludge:cellulose:lignin was 1:1:0.4, the main co-pyrolysis temperature range was narrower, the ultimate pyrolysis weight loss was more, and the synergistic effect had a longer duration time. When the pyrolysis temperature was below 400°C, the addition of the lignin could promote the co-pyrolysis process of the cellulose and the sludge, such as the decrease of the activation energy E.
Investigation of Secondary Organic Aerosol Formation from Different Sources and Ambient Environments

To investigate atmospheric processing of direct urban and biomass burning emissions, I modified and deployed an oxidation flow reactor with submicron aerosol size and chemical composition measurements during FLAME-3, a biomass-burning study at USDA Fire Sciences Laboratory in Missoula, MT, and CalNex, a field study investigating the nexus of air quality and climate change at a receptor site in the LA-Basin at Pasadena, CA. The reactor produces OH concentrations up to 4 orders of magnitude higher than in ambient air, achieving aging by OH reactions in less than 5 minutes that is equivalent to ~2 weeks in the atmosphere. The OH exposure (OHexp) was stepped every 20 min in both field studies. Results show the value of this approach as a tool for in-situ evaluation of changes in OA concentration and composition due to photochemical processing. In FLAME-3, the average OA enhancement factor was 1.42 ± 0.36 of the initial POA. Reactive VOCs, such as toluene, monoterpenes, and acetaldehyde, decreased with increased OHexp; however, formic acid, acetone, and some unidentified OVOCs increased after significant exposure. Net SOA formation in the photochemical reactor increased with OHexp, typically
Impact of Improved Rice Variety on Productivity and Crop Diversity: A Case of Singye Gewog (Block) in Sarpang District of Southern Bhutan

The survey was conducted in 2019 to generate baseline information for rice yield and varietal diversity, involving 54 experienced rice farmers of Singye Gewog (block) under Sarpang Dzongkhag (district) in Southern Bhutan. A total of 9 varieties were found under cultivation, of which 2 and 7 were assessed to be improved varieties and landraces respectively. The mean yield of improved varieties was 1253.2 kg acre, whereas landraces yielded 777.1 kg acre (P=.006). The chronological varietal diversity revealed that 47.05% of farmer-named varieties were either lost or replaced over 20 years. However, landrace such as Choti Mahsino was popular, covering 24.6% of the rice cultivated area. Further, taste, yield stability, and utility for festivals were the main reasons for perpetuating landraces’ cultivation. The study showed the positive impact of improved varieties on productivity while it has narrowed varietal diversity. On the flip side, the current research found that only one improved variety was adopted which shows a need to promote improved varieties, while the improvement of landraces should also be given priority.

Maturity and Well-Being: Consistent Associations Across Samples and Measures

Among the earliest questions posed by philosophers around the world was how to live a fruitful and ultimately satisfying life. Millennia later, psychologists find themselves tackling the same question, focusing their answers primarily on the psychological precursors of well-being [1]. Despite an abundance of different psychological models of well-being, it is often construed as consisting of two broad dimensions [2-4]. The first dimension represents subjective well-being: A person’s self-reported feelings of happiness, satisfaction with life, optimism, and self-esteem. The second dimension represents growth and evidence of one’s well-being, including self-actualization, self-improvement, positive relations with others, and evidence of having a sense of purpose or direction. Various researchers have used different terms to describe these two dimensions, including subjective and psychological well-being [4], subjective well-being and growth [2], and hedonic and eudaimonic well-being [1]. Despite these differences in terminology, however, they all construe well-being as multifaceted and aim to understand the precursors to well-being. In the present research we aim to contribute to this ever-increasing list of precursors to well-being by examining a relatively under-studied, but conceptually relevant variable, perceived maturity, and its association with a well-being indicators.
The Second International Conference on Humanities ORGANIZATIONAL COMMITMENT AMONG KNOWLEDGE WORKERS: A REVIEW

This paper presents a series of literature review on organizational commitment among knowledge workers and discusses other factors which influences organizational commitment but are usually given little attention to. Despite of all the studies that have been conducted in the past decade, researchers have yet to come to an agreement on the characteristics of organizational commitment and how it develops among employees. With that in mind, it is necessary to define organizational commitment clearly and how it plays a role in retaining employees as well as augmenting organization performance. This paper includes a figure that encompasses of the antecedents of organizational commitment among knowledge workers. These antecedents were categorized into five categories; specifically, personal characteristics, job satisfaction, organizational justice, role states and employee perceptions. Thus, this paper proposes to function as a modern review, analysis and synthesis of the organizational commitment. Along with that, this paper intends to prepare a foundation for future researchers and practitioners studying organizational commitment among knowledge workers. © 2019 Published by Future Academy www.FutureAcademy. org.UK
Relationship between gastroesophageal reflux disease and laparoscopic sleeve gastrectomy: a narrative review

This paper aims to revisit the relationship between gastroesophageal reflux disease and laparoscopic sleeve gastrectomy in obese patients by reviewing the recent available literature, in the form of a narrative review. The interpretation of the current evidence is challenged by the fact that published data are contradictory and comparison between studies is difficult. Most studies investigate the presence of gastroesophageal reflux disease by assessing only the symptoms reported by patients. A few studies have objectively investigated gastroesophageal reflux disease by functional tests and endoscopic evaluation. Also, the surgical technique of laparoscopic sleeve gastrectomy plays an important role in the incidence of postoperative gastroesophageal reflux disease. In conclusion, surgeons must be aware of the existence of gastroesophageal reflux disease and, at the same time, patients should be informed regarding the possible effect of laparoscopic sleeve gastrectomy on gastroesophageal reflux disease.
