Moderating Claims and Disputes through Collaborative Procurement Abstract Purpose: Following the global financial crisis in 2008, the construction sector in UAE has been facing emergent criticisms for growing adversarial culture and rising prevalent claims and disputes

Purpose: Following the global financial crisis in 2008, the construction sector in UAE has been facing emergent criticisms for growing adversarial culture and rising prevalent claims and disputes between stakeholders. The complex, large size and fast track nature of construction projects in UAE, make project management very challenging under the commonly used traditional procurement routes. This paper aspires to examine whether implementing collaborative procurement approaches can facilitate resolving the escalating number of claims and disputes in the UAE construction industry. Design/methodology/approach: Considering the nature of the study, a quantitative method was selected to realize the research objectives. The questionnaire was uploaded using online survey facility and distributed through e-mails and professional networks. The questionnaire was piloted with experts to assess whether the questions are unambiguous, easy to respond and intelligible. The feedbacks received were mostly positive with few comments and recommendations. The pilot responses were incorporated and the questionnaire was modified before the final sending out. The questionnaire survey consisted of six main sections to fulfill the research objectives. Findings: Around three-quarters of the experts believe that the relationship is adversarial, with lack of trust, win-lose attitude, with dismissive and opportunistic behavior. The survey reveals that the top causes of claims and disputes comprise: (a) variations due to clients initiated change requests; (b) contractors selection on low bid only rather than including quality and performance considerations; and (c) unfair risk allocation where majority of risks are transferred to contractors. The findings also identify eight collaborative practices which have crucial positive impact such as: (1) early identification of problems; (2) better communication; (3) enhanced trust and teamwork. Originality/value: This research contributes to the enhancement of the management of claims and disputes for construction projects, which encompasses: (a) the key characteristics of collaborative arrangements to improve the adversarial construction culture comprise: mutual respect, openness, fairness and non-opportunistic behaviours; (b) the foremost roles of collaborative procurement in reducing claims and disputes embrace: early identification and resolution of problems, enhanced trust and teamwork spirit, improved relationships and better quality communication; (c) the major practical barriers of implementing collaborative approaches incorporate: lack of awareness of their benefits, primitive legal framework of partnering arrangements, lack of transparency in procurement processes.
Histone methyltransferase SETD2: a potential tumor suppressor in solid cancers

Epigenetic regulation plays an important role in the occurrence, development and treatment of malignant tumors; and a great deal of attention has been paid to the histone methylation level in recent years. As a 230-kD epigenetic regulator, the histone H3 lysine 36 histone (H3K36) methyltransferase SETD2 is a key enzyme of the nuclear receptor SET domain-containing (NSD) family, which is associated with a specific hyperphosphorylated domain, a large subunit of RNA polymerase II (RNAPII), named RNAPII subunit B1 (RPB1), and SETD2 which methylates the ly-36 position of dimethylated histone H3 (H3K36me2) to generate trimethylated H3K36 (H3K36me3). SETD2 is involved in various cellular processes, including transcriptional regulation, DNA damage repair, non-histone protein-related functions and some other processes. Great efforts of high-throughput sequencing have revealed that SETD2 is mutated or its function is lost in a range of solid cancers, including renal cancer, gastrointestinal cancer, lung cancer, pancreatic cancer, osteosarcoma, and so on. Mutation, or functional loss, of the SETD2 gene produces dysfunction in corresponding tumor tissue proteins, leading to tumorigenesis, progression, chemotherapy resistance, and unfavorable prognosis, suggesting that SETD2 possibly acts as a tumor suppressor. However, its underlying mechanism remains largely unexplored. In the present study, we summarized the latest advances of effects of SETD2 expression at the mRNA and protein levels in solid cancers, and its potential molecular and cellular functions as well as clinical applications were also reviewed.
Enhancing school leadership: Meeting the challenges of HIV and AIDS

Over time the role of school leadership in South African schools has become increasingly complex. School leaders, often with very little support or training, are required to respond to and then implement a series of sophisticated education policies. While it has become impossible to ignore the impact of HIV and AIDS on the lives of teachers and learners, school leaders also have to respond to the socio-economic circumstances in their school communities. Research conducted by the South African Institute for Distance Education showed that many school leaders began intuitively to respond to these challenges by creating networks of support for learners around their schools. The research also showed that while the form these networks took unfolded in different ways, many of them resulted in schools implementing learner support programmes around nutrition, aftercare and counselling. While in some schools these initiatives were ad hoc, examples were also found of schools where the approach to implementation and management of these support programmes was more systematic and thus more sustainable. In contrast, this research also showed that while many school leaders were able to respond to learner needs, there was very little evidence to suggest that schools were equally able to respond to the needs of their teachers. Through presenting an analysis of the support strategies, this paper starts to provide an interesting and informative picture of how the landscape of school leadership has begun to evolve in some South African schools.
Natural Convection From an Elliptic Tube with Major Axis Vertical and with Uniform Surface Heat Flux

are the modified Rayleigh number, Ra Prandtl number, Pr and axis ratio, Ar. The Ra is considered up to lo7 , the Pr is considered up to 10 while the axis ratio is varied from 0.05 (almost flat plate) to 0.998 ( almost circular cylinder). Results are presented for the local and average Nusselt numbers and local and mean surface temperatures. The study revealed that as Rayleigh number andlor Prandtl number increase the average Nusselt number increases, resulting in a decrease in mean surface temperature. On the other end, the study showed that the effect of axis ratio on the average Nusselt number is not significant with only smaller decrease in average Nusselt number as the axis ratio i increases. 5
Unusual Metastatic Thyroid Carcinoma to the Liver and the Kidneys: A Case Report

Papillary Thyroid Carcinoma (PTC) is the most common differentiated histological entity of thyroid cancer occurring for approximately 80% of all primary thyroid cancers [1]. In the majority of cases, PTC is a localized disease confined to neck with a high spread of regional cervical lymph nodes involvement [2]. Hematogenous distant metastases from PTC are rare, occurring in less than 10% and primarily include lungs and bones [3].
Internationalization effects on financial performance: The case of Portuguese industrial SMEs

The objective of this paper is to empirically examine the relationship between the firms’ degree of internationalization and their financial performance. The literature about performance determinants is abundant however, the relation between internationalization and profitability in the context of Small and Medium Enterprises (SMEs) is much less studied. It used an unbalanced panel data of 4.133 Portuguese industrial SMEs for the period from 2010 to 2016 and applied a random effects model. The results indicate that internationalization, measured as export intensity/diversity/distance, influences firm profitability, in particular when exports are directed to distant markets and conducted by small firms. Also, the presence of a non-linear relationship between internationalization and profitability calls for managers’ attention to its dysfunctional consequences for firm performance, especially at intermediate levels of internationalization. Due to SMEs relevance in the majority of the economies, our results and its implications can be generalized to other countries.
Disturbance cues as a source of risk assessment information: Effects of sender identity and experience with risk on the response of Trinidadian guppies (Poecilia reticulata)

Chemical cues are commonly used by aquatic vertebrates to assess local threats and facilitate behavioural decision-making. Disturbance cues are ‘early warning signals’ common among aquatic vertebrates, that warn conspecific and heterospecific prey guild members of potential risks. Recent studies suggest that disturbance cues may play an important role in the predation sequence, providing prey with valuable information that affords the opportunity to interrupt the predation sequence and successfully avoid predator encounters. However, little is known about the informational content of disturbance cues and what factors influence the response patterns to these cues. Therefore, we assessed the role of species-specificity and prior experience with predation risk on the information content conveyed by disturbance cues. First, we tested whether receivers exhibit graded antipredator responses to cues from either 10 or 20 conspecific and heterospecific senders. Receivers increased the intensity of their antipredator response to cues from 20 compared to 10 conspecific donors. However, we found that while receivers respond to heterospecific disturbance cues, there was no effect of donor group size, suggesting that there may be a degree of species-specificity of disturbance cues. Second, using wild-caught and laboratory-reared fish, we tested whether senders and receiver responded differentially to disturbance cues if they had prior experience with predation risk. The response of high-risk fish was dependent upon the source of disturbance cue senders (high vs. low risk). However, guppies collected from a low-risk site exhibited similar responses to disturbance cues, regardless of the sender population. Combined, our results demonstrate that disturbance cues may serve as a more elaborate form of risk assessment information than previously thought, and that the response to these cues is, at least in part, dependent upon both the sender’s and receiver’s recent experience with predation.
Assessing global water mass transfers from continents to oceans over the period 1948–2016

Abstract. Ocean mass and thus sea level is significantly affected by water storage on the continents. However, assessing the net contribution of continental water storage change to ocean mass change remains a challenge. We present an integrated version of the WaterGAP global hydrological model that is able to consistently simulate total water storage anomalies (TWSAs) over the global continental area (except Greenland and Antarctica) by integrating the output from the global glacier model of Marzeion et al. (2012) as an input to WaterGAP. Monthly time series of global mean TWSAs obtained with an ensemble of four variants of the integrated model, corresponding to different precipitation input and irrigation water use assumptions, were validated against an ensemble of four TWSA solutions based on the Gravity Recovery and Climate Experiment (GRACE) satellite gravimetry from January 2003 to August 2016. With a mean Nash–Sutcliffe efficiency (NSE) of 0.87, simulated TWSAs fit well to observations. By decomposing the original TWSA signal into its seasonal, linear trend and interannual components, we found that seasonal and interannual variability are almost exclusively caused by the glacier-free land water storage anomalies (LWSAs). Seasonal amplitude and phase are very well reproduced (NSE=0.88). The linear trend is overestimated by 30 %–50 % (NSE=0.65), and interannual variability is captured to a certain extent (NSE=0.57) by the integrated model. During the period 1948–2016, we find that continents lost 34–41 mm of sea level equivalent (SLE) to the oceans, with global glacier mass loss accounting for 81 % of the cumulated mass loss and LWSAs accounting for the remaining 19 %. Over 1948–2016, the mass gain on land from the impoundment of water in artificial reservoirs, equivalent to 8 mm SLE, was offset by the mass loss from water abstractions, amounting to 15–21 mm SLE and reflecting a cumulated groundwater depletion of 13–19 mm SLE. Climate-driven LWSAs are highly sensitive to precipitation input and correlate with El Niño Southern Oscillation multi-year modulations. Significant uncertainty remains in the trends of modelled LWSAs, which are highly sensitive to the simulation of irrigation water use and artificial reservoirs.
Evaluation of Ashwagandha (Withania Somnifera) and its Extract to Protecting he Liver From Damage

This study was achieved to the safety evaluation of the ashwagandha (Withania somnifera) and total phenolic acid and total flavonoids compounds were determined, as well as ABTS and DPPH radical scavenging activities assay were studied. In addition, the biological experimental and histological assay was an examination of hepatitis rats. The results observed that the ashwagandha root extract was safety due to do not evidence of toxic effect or mortality in mice. This safety from the ashwagandha root extract caused the extract had contained high amounts of phenolic and flavonoids compounds which directly role of in free radical scavenging, thus the extract from ashwagandha root is a source of antioxidant activity. At the end of biological experimental after eight weeks the results were found that the effects of ashwagandha roots extract on carbon tetrachloride CCl4-treated induced alterations in serum hepatic enzymes were decreased than control CCl4 positive and give nearly equal control negative at level 400mg/kg body weight for a rat. Moreover, the results found that the effect ashwagandha roots extract on antioxidant enzymes hepatic as glutathione (GSH), superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GPx), and catalase (CAT) parameters showed that the ashwagandha roots extract was improvement the antioxidant enzymes. Furthermore, different concentrations extract alleviated histopathological changes in rats' liver treated with CCl4. Ashwagandha root extracts confirmed that the protection of the rats' liver CCl4induced hepatotoxicity. This influence may be due to activated, the antioxidant activities of these extracts. In recommending that the obviously results supported that the possible anti hepatic damage effect of ashwagandha root extract against CCl4-induced hepatic damage. This anti hepatic damage influence may be due to activated, the antioxidant activities
Wu, Q and Edensor, T and Cheng, J (2018)Beyond Space: Spatial (Re)production and Middle Class Remaking Driven by Jiaoyufication in Nan-

As an extension of gentrification, high quality education-driven jiaoyufication not only displaces previous lower class as jiaoyufiers, but also replaces former jiaoyufiers with newcomers, as well as blenching former blue collar neighborhoods. New middle class communities are emerging as spatially limited education-apartment zones attract social groups who attempt to occupy these spaces to facilitate social mobility and consolidation, causing tension between them. Consequently, jiaoyufication has narrowed down opportunities for intra-generation-based social mobility and exacerbated social polarization, gradually replacing traditional social hierarchies with an intergeneration-based neoliberal stratification.
Nutrition assessment of patients with AMD

The aim of the study was to assess the nutritional habits of AMD patients from the Szczecin region. Age-related macular degeneration (AMD) is a chronic, progressive eye disease that results in loss of central vision. The study was conducted in the Ophthalmology Clinic of the Independent Public Teaching Hospital No. 2, Pomeranian Medical University (PUM) in Szczecin among 46 subjects. The interview method was used using the author's questionnaire, which contained questions about age, body weight and height, sex, composition of the three-day menu and the form of AMD. Insufficient intake of numerous nutrients (with lutein and zeaxanthin among them) has been shown, which may accelerate the progression of the disease. In addition, patients were underweight, which may increase the risk of protein-energy malnutrition that may affect the development of AMD.
Evaluation of the methods used for impression making for different implant systems in prosthetic dentistry Avaliação dos métodos usados para moldagem em diferentes sistemas de implantes em prótese dental

Fabrication of an implant supported fixed or removable-partial-denture requires precise transfer of the intraoral structures and the implant components to the plaster model. With the increase in the number of implant systems, impression making procedures also increased depending on each system. This article summarizes and describes the procedures and factors that affect adequate impression making for several implant systems based on the information from English peer-reviewed journals identified by a Medline search covering the years from 1979-2005, text books, and the information obtained from the manufacturers of the most commonly used implant systems. Clinical relevance: since impression making methods vary depending on each implant system, clinicians should study the procedures for each system in order to achieve successful implant supported fixedor removable-partial-dentures.
Accident Analysis and Prevention

Background: Much of the driver distraction and inattention work to date has focused on concerns over drivers removing their eyes from the forward roadway to perform non-driving-related tasks, and its demonstrable link to safety consequences when these glances are timed at inopportune moments. This extensive literature has established, through the analyses of glance from naturalistic datasets, a clear relationship between eyes-off-road, lead vehicle closing kinematics, and near-crash/crash involvement. Objective: This paper looks at the role of driver expectation in influencing drivers’ decisions about when and for how long to remove their eyes from the forward roadway in an analysis that consider the combined role of onand off-road glances. Method: Using glance data collected in the 100-Car Naturalistic Driving Study (NDS), near-crashes were examined separately from crashes to examine how momentary differences in glance allocation over the 25-s prior to a precipitating event can differentiate between these two distinct outcomes. Individual glance metrics of mean single glance duration (MSGD), total glance time (TGT), and glance count for off-road and on-road glance locations were analyzed. Output from the AttenD algorithm (Kircher and Ahlström, 2009) was also analyzed as a hybrid measure; in threading together onand off-road glances over time, its output produces a pattern of glance behavior meaningful for examining attentional effects. Results: Individual glance metrics calculated at the epoch-level and binned by 10-s units of time across the available epoch lengths revealed that drivers in near-crashes have significantly longer on-road glances, and look less frequently between onand offroad locations in the moments preceding a precipitating event as compared to crashes. During on-road glances, drivers in near-crashes were found to more frequently sample peripheral regions of the roadway than drivers in crashes. Output from the AttenD algorithm affirmed the cumulative net benefit of longer on-road glances and of improved attention management between onand off-road locations. Conclusion: The finding of longer on-road glances differentiating between safety-critical outcomes in the 100-Car NDS data underscores the importance of attention management in how drivers look both on and off the road. It is in the pattern of glances to and from the forward roadway that drivers obtained critical information necessary to inform their expectation of hazard potential to avoid a crash. Application: This work may have important implications for attention management in the context of the increasing prevalence of in-vehicle demands as well as of vehicle automation.
Perceptions of education quality in the context of the Bologna process in a regional university

This article considers perceptions of quality in higher education (HE). This work examines the academic staff perceptions of how education quality is affected by the engagement of the country’s HE in the Bologna Process; particular attention is paid to a regional university. The study was conducted to understand academic staff perception of education quality in relation to Kazakhstani integration into European higher education area (EHEA). The article provides an analysis of the interviews with academic staff at a regional university in order to learn about the realisation process and the challenges faced by the university due to its accession to the Bologna Process and how the process affects the overall quality of HE. The perceptions of academic staff on HE quality and the extent to which the quality of HE has changed with the engagement in the new system are analysed.
Posaconazole versus Itraconazole as Prophylactic Antifungal Agents during Induction Chemotherapy for Acute Myeloid Leukemia: A Real-World Single Center Comparison

Objective: To prevent invasive fungal disease (IFD) in acute myeloid leukemia (AML) patients, the use of posaconazole as a prophylactic antifungal agent has become standard in patients undergoing induction chemotherapy. However, there are few data comparing itraconazole and posaconazole as prophylactic antifungal agents in the real world. Methods: Patients at the Soonchunhyang University Seoul Hospital, who were treated with itraconazole or posaconazole for preventing IFD during induction chemotherapy for AML from January 2009 to April 2018, were included in the study. The collected clinical data were reviewed, and IFD was diagnosed using the revised definition of IFD from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group. Results: A total of 53 patients were recruited to receive either posaconazole (n= 29) or itraconazole (n= 24). IFD occurred in seven patients (29.1%) who used posaconazole and in six patients (20.6%) who used itraconazole for antifungal prophylaxis (P= 0.475). The 100-day mortality rate was 4 (13.8%) in the posaconazole group and 2 (8.3%) in the itraconazole group (P= 0.535). Conclusion: There was no significant difference in the incidence of IFD and 100-day mortality between the patients with induction chemotherapy for newly diagnosed AML who received posaconazole and itraconazole as prophylactic antifungal agents. These results suggest that it would be worthwhile to ascertain whether posaconazole is widely known as a better approach than itraconazole as prophylactic antifungal agents in the real-world.
