Key risks in construction projects in Italy: contractors’ perspective

Purpose Risks play an important role in the success of construction projects. Failure in identification and assessment of risks can lead to inadequacy in the process of managing risks, which in turn can critically affect the projects’ resources. A formal risk management is rarely practised in construction projects due to the lack of contractors’ awareness of key risks. The purpose of this paper is to focus on the investigation of risk factors in construction projects in Italy from contractors’ perspective. Design/methodology/approach Semi-structured interviews were conducted to collect data, based on which a total of ten key risks were ascertained. The identified risks were compared with the findings of the surveys conducted in the Australian and Chinese construction industry to address the unique risks associated with construction projects in Italy. Findings The key risks included delays in payments, client variations, design variations, inaccurate cost estimates, and tight project schedules. The comparison between those three countries specified the delays in payments and project funding problems as the most critical factors that are related to cultural influences and behaviour of clients. The findings assist contractors in the risk identification process, and can be applied to the development of a risk management framework for construction projects. Research limitations/implications The findings of this study cannot be generalised statistically for the whole of Italy as it was constrained geographically, with respondents drawn only from a self-selection sample of construction projects in the Veneto region of Northern Italy. The findings represent a snapshot of the key potential internal and external risks from the perspective of contractors. Originality/value The results of the study specified the key risks of construction projects from the perspective of contractors which can contribute to risk management for construction projects.
Covering the Home Nation at Its Home Games: An Analysis of Australian Nationalistic Broadcast Coverage of the 2018 Commonwealth Games

This study explored how nationalism unfolded within the Australian broadcast of the 2018 Commonwealth Games that were held on the Gold Coast, Australia. Applying social-categorization theory, over 31 hours of the total coverage was content analyzed for name mentions, description of success or failure, and personality and physicality of the athletes. Results of this study underscore large differences in the amount of commentary that was provided to Australians and non-Australians during the broadcasts, with Australians being mentioned more than non-Australian athletes. As Australia performed well at the Commonwealth Games, Australians featured highly on both the top most-mentioned athletes list and the overall percentage of name mentions also favored Australians. The Seven Network emphasized Australian athletes to its viewers, as Australian viewers would share many of the group characteristics with athletes who were featured on television. This study contributes to the literature by uncovering how in-group members were portrayed in the Australian sports context while also providing insight into how consumers’ media consumption could potentially affect how the network broadcasts the Commonwealth Games from a nationally partisan perspective.

A Successful Case of Hepatocellular Carcinoma Treated with Atezolizumab Plus Bevacizumab with Multisystem Immune-related Adverse Events

A 63-year-old man with hepatitis C was treated with atezolizumab plus bevacizumab for unresectable diffuse hepatocellular carcinoma (HCC). After four cycles of atezolizumab plus bevacizumab, the diffuse HCC markedly shrank; however, he complained of general fatigue, loss of appetite, and slight loss of muscle strength in the lower legs. He was diagnosed with isolated adrenocorticotropic hormone deficiency (IAD), hypothyroidism, and myopathy, suggesting multisystem immune-related adverse events (irAEs). After administration of hydrocortisone, the clinical symptoms rapidly disappeared. Patients with multisystem irAEs can have favorable outcomes; thus, to continue immune-checkpoint inhibitors therapy, a correct diagnosis and management of multisystem irAEs are important.
Ibn Taymiyyah’s “Mardin Fatwa” and the Mongols: An Analysis

The so-called “Mardin Fatwa” is Ibn Taymiyyah’s (d. 728/1328) description of Mardin city’s status as an Islamic state and its Islamic population. Yahya Michot (b. 1952) and ‘Abd Allah Bayyah’s (b. 1935) modern day readings of this fatwa emphasise different attitudes towards Mongols: Michot emphasised the word yuqātal (should be fought) in his reading of the text while Bayyah emphasised the word yu’āmal (should be justly treated). This seemingly small difference has had a large impact on Muslims’ understanding of fatwa. For instance, these two readings might alter readers’ perceptions of fatwa as either a literal or metaphorical spiritual battle. This article is grounded in a multidisciplinary approach that combines the selection, translation and critical reading of the selected sources with historical research. The overall approach followed in this article is best described as inductive. This article analyses Michot and Bayyah’s readings through a close reading of the fatwa itself. It concludes by deducing that the Mardin Fatwa text really does represent Ibn Taymiyyah’s opinion and that Yahya Michot’s reading of the text is the correct one.
Election Fraud and Misinformation on Twitter: Author, Cluster, and Message Antecedents

This study determined the antecedents of diffusion scope (total audience), speed (number of adopters/time), and shape (broadcast vs. person-to-person transmission) for true vs. fake news about a falsely claimed stolen 2020 US Presidential election across clusters of users that responded to one another’s tweets (“user clusters”). We examined 31,128 tweets with links to fake vs. true news by 20,179 users to identify 1,069 user clusters via clustering analysis. We tested whether attributes of authors (experience, followers, following, total tweets), time (date), or tweets (link to fake [vs. true] news, retweets) affected diffusion scope, speed, or shape, across user clusters via multilevel diffusion analysis. These tweets showed no overall diffusion pattern; instead, specific explanatory variables determined their scope, speed, and shape. Compared to true news tweets, fake news tweets started earlier and showed greater broadcast influence (greater diffusion speed), scope, and person-to-person influence. Authors with more experience and smaller user clusters both showed greater speed but less scope and less person-to-person influence. Likewise, later tweets showed slightly more broadcast influence, less scope, and more person-to-person influence. By contrast, users with more followers showed less broadcast influence but greater scope and slightly more person-to-person influence. These results highlight the earlier instances of fake news and the greater diffusion speed of fake news in smaller user clusters and by users with fewer followers, so they suggest that monitors can detect fake news earlier by focusing on earlier tweets, smaller user clusters, and users with fewer followers.
Spray-Drying Hen Eggs: Effects of the Egg Yolk to Egg White Ratio and Sucrose Addition on the Physicochemical, Functional, and Nutritional Properties of Dried Products and on Their Amino Acid Profiles

Manufactured egg powders can be formulated to produce food products that vary in their properties. The present study aims to determine the effect of egg white content on the physicochemical characteristics and on the functionality and nutritional value of dried whole egg (WE), egg white (W), and an egg yolk/white mixture in a 1:3 ratio (M1:3). These fresh egg products were spray-dried using sucrose—an agent recognized for its effect of protecting the protein in the egg during the drying process. Experiments were conducted in a laboratory-scale spray dryer, operated under controlled conditions, with an air inlet temperature of 120 °C. In the dried products, water activity, water solubility index, color, and pH were affected significantly as a function of the fresh egg component ratio and the added sucrose. The wettability and dispersibility in water of egg powder were improved when sucrose was added to the WE. The water-holding capacity was highest in dried egg white, and higher in the M1:3 mixture without sucrose added than in the WE with 5% sucrose. The results suggest that modifying the ratio of fresh egg yolk to egg white could lend some control over the protein and fat contents of dried egg products and over their functional properties.
Structural Characteristics of Insoluble Dietary Fiber from Okara with Different Particle Sizes and Their Prebiotic Effects in Rats Fed High-Fat Diet

Dietary fiber, which is utilized to make functional meals, is an important component for promoting human health and managing calorie consumption. In this study, three different particle sizes of OIDF (Okara insoluble dietary fiber) were characterized. Their lipid-lowering effects and the impacts on gut microbiota were determined by OIDF intervention in high-fat diet rats. Scanning electron microscopy (SEM) results showed that the three particle sizes of OIDF have different morphologies. Fourier transform infrared spectroscopy (FT-IR) results showed that the three sources of IDF samples have similar active groups, but the thermogravimetric analysis/differential scanning calorimetry (TGA/DSC) and X-ray diffraction (XRD) showed that three different particle sizes of OIDF have different retention and crystallinity. Among the three OIDFs, OIDF-10 exhibited the stronger WSC, OHC, CAC, and SCAC. The results after the feeding showed that the OIDF of three particle sizes could improve the elevation of blood lipids and the disturbance of gut microbiota caused by the high-fat diet. Therefore, this study demonstrated the functional significance of the three particle sizes of OIDF and provided a reference for its application in functional food processing, aiming at maintaining healthy blood lipid and intestinal flora levels.
A Comprehensive Analysis of Today’s Malware and its Distribution Network: Common Adversary Strategies and Implications

Malware has plagued the internet and computing systems for decades. The war against malware has always been an arms race. Researchers and industry have constantly improved detection and prevention methodologies against increasingly more evasive malware. Keeping up with the constantly changing adversary tactics for evading defensive efforts and maintaining an efficient malware supply chain is imperative to stay ahead in the competition. In this paper, we present a large-scale and comprehensive analysis of the current state of malware distribution. For the analysis, we accumulated a dataset that contains 99,312 malware binary samples from 38,659 malware distribution sites over 287 days. Using our dataset, we perform a comprehensive analysis of the collected malware binaries and URLs to provide up-to-date statistics and insights into the adversary strategies. We analyze both malware distribution sites and malware binaries collected from them. Regarding binary analysis, we perform a multifaceted analysis on the characteristics on the collected binaries, including malware family label classification and file similarity-based clustering. With distribution site analysis, we analyze the IP addresses, domains, AS registration distribution and URL lexical distribution of malware distribution sites. We further discuss the statistical relationship between malware families and their distribution domains. Most importantly, we discuss the current trends in malware distribution today and reveal adversary strategies through our extensive amount of analysis results. Then, we suggest future directions for fight against malware distribution.
Using formal and informal formative assessment to support bilingual argument mapping in university bilingual science courses

ABSTRACT The rise in university bilingual science courses is explained by a certain phenomenon, the internationalization of higher education. Bilingual Argument Mapping (BAM) – the ability to construct argument maps using two languages – is a key aspect of bilingual scientific literacy. An argument map is a visual representation of argument structure. The problem is that little is known about how to foster BAM in this type of course. The goal of this study was to explore the possibility of using formal and informal formative assessment (FIFA) – a type of assessment for learning in which feedback is both preplanned and instantaneous –, to support undergraduates’ BAM. The data consist of the bilingual argument maps constructed by forty-four students (27 females and 17 males, 18–23 years old) in Colombia during a university Spanish-English bilingual science course. Results indicate that FIFA helped the participants’ creation of valid and coherent argument maps in Spanish, in English and in a hybrid version using code-switching as response to argumentative questions related to the scientific topics covered in the course. The potential contributions of FIFA and its implications are discussed in light of research and theory of bilingual science education.
Distributed Antittack Fault-Tolerant Tracking Control for Vehicle Platoon Systems Under Cyber-Physical Threats

Vehicle platoon systems are considered as automatous vehicles in a platoon-based driving pattern in which a following vehicle follows the preceding vehicle and maintains the desired vehicle spacing. This article investigates the leader-following tracking issue of vehicle platoon systems under cyber-physical threats with the distributed antiattack fault-tolerant tracking control strategy. In this study, vehicle platoon systems, complicated actuator faults in physical layer, and connectivity-mixed attacks in the cyber layer are modeled, respectively. Decentralized fault-estimation unknown input observer and distributed antiattack fault-tolerant tracking control designs are developed in an integrated control framework to guarantee the robust and resilient tracking property of estimation errors and platoon tracking errors as well as the reliable intervehicle spacing by virtue of attack activation rate and attack frequency metrics. Simulations validate the proposed distributed antiattack fault-tolerant tracking control algorithm in pernicious cyber-physical threatened scenarios.
Regulation of the Actin Cytoskeleton-Linked Ca2+ Signaling by Intracellular pH in Fertilized Eggs of Sea Urchin

In sea urchin, the immediate contact of the acrosome-reacted sperm with the egg surface triggers a series of structural and ionic changes in the egg cortex. Within one minute after sperm fuses with the egg plasma membrane, the cell membrane potential changes with the concurrent increases in intracellular Ca2+ levels. The consequent exocytosis of the cortical granules induces separation of the vitelline layer from the egg plasma membrane. While these cortical changes are presumed to prevent the fusion of additional sperm, the subsequent late phase (between 1 and 4 min after fertilization) is characterized by reorganization of the egg cortex and microvilli (elongation) and by the metabolic shift to activate de novo protein and DNA syntheses. The latter biosynthetic events are crucial for embryonic development. Previous studies suggested that the early phase of fertilization was not a prerequisite for these changes in the second phase since the increase in the intracellular pH induced by the exposure of unfertilized sea urchin eggs to ammonia seawater could start metabolic egg activation in the absence of the cortical granule exocytosis. In the present study, we have demonstrated that the incubation of unfertilized eggs in ammonia seawater induced considerable elongations of microvilli (containing actin filaments) as a consequence of the intracellular pH increase, which increased the egg’s receptivity to sperm and made the eggs polyspermic at fertilization despite the elevation of the fertilization envelope (FE). These eggs also displayed compromised Ca2+ signals at fertilization, as the amplitude of the cortical flash was significantly reduced and the elevated intracellular Ca2+ level declined much faster. These results have also highlighted the importance of the increased internal pH in regulating Ca2+ signaling and the microvillar actin cytoskeleton during the late phase of the fertilization process.
Classification of Huntington’s Disease Stage with Features Derived from Structural and Diffusion-Weighted Imaging

The purpose of this study was to classify Huntington’s disease (HD) stage using support vector machines and measures derived from T1- and diffusion-weighted imaging. The effects of feature selection approach and combination of imaging modalities are assessed. Fourteen premanifest-HD individuals (Pre-HD; on average > 20 years from estimated disease onset), eleven early-manifest HD (Early-HD) patients, and eighteen healthy controls (HC) participated in the study. We compared three feature selection approaches: (i) whole-brain segmented grey matter (GM; voxel-based measure) or fractional anisotropy (FA) values; (ii) GM or FA values from subcortical regions-of-interest (caudate, putamen, pallidum); and (iii) automated selection of GM or FA values with the algorithm Relief-F. We assessed single- and multi-kernel approaches to classify combined GM and FA measures. Significant classifications were achieved between Early-HD and Pre-HD or HC individuals (accuracy: generally, 85% to 95%), and between Pre-HD and controls for the feature FA of the caudate ROI (74% accuracy). The combination of GM and FA measures did not result in higher performances. We demonstrate evidence on the high sensitivity of FA for the classification of the earliest Pre-HD stages, and successful distinction between HD stages.
Ankle and Knee Joint Kinematics Differ between Flat, Slice and Topspin Serves in Young Tennis Players

The present study aimed to examine the differences in ankle and knee joint kinematics between the flat, slice, and topspin tennis serves. Twelve young tennis players (six boys, and six girls) aged 12-16 years old, performed flat, slice and topspin serve whilst three-dimensional body kinematics were recorded using an optoelectronic camera system. Ankle plantarflexion/dorsiflexion and knee extension/flexion angular positions were recorded at two-time instants: first, at the time of maximum knee flexion and, second, at time of ball to racket contact. Analysis of variance designs showed that the knee flexion angle of the back leg differed significantly between the three service types (P < 0.001). Further, the rear leg ankle angle at maximum flexion also significantly differed between the three serves (P < 0.004). It was observed that tennis players perform topspin and slice serves with smaller joint angles than flat serves, probably, because the former is being used as a second serve in the game. Τhe ankle, which is the closest point of the kinetic chain at the start of power generation, plays an important and different role in the performance of the three serve types. Therefore, the synergy of the ankle joint is very important in the initial phase of serve for the transfer of forces. Coaches should review the technical issues of serve movement based on the flexibility of the ankle joint because the limited ankle range of motion does not help to transfer forces from the ground.
Empowering Citizen Science: A GenericData Collection Framework

Citizen Science (CS) is collaboration between scientists and citizens to expand opportunities for scientific data collection and problem solving. Recent advancements such as the Internet, social networks and smart devices have created a technological platform for CS to engage more citizens to work on a wide range of scientific problems. Due to technical, financial and management resource constraints many organisations struggle to develop effective tools to collect scientific data in CS projects. A robust web and mobile interface for scientific data collection will ensure collection of higher quality scientific data. While web and mobile applications have been developed for some CS projects many CS projects are hindered by the complexity and intrinsic costs of implementing these applications. This thesis describes a web-based model for CS data collection suitable for both small CS communities and larger scientific organisations. Offering features commonly used in CS projects, this model reduces costs associated with software implementation and management in CS. A CS campaign is undertaken as a case study that validates our model in a real world scenario. Overall the generic data collection framework presented will empower communities and organisations to engage and use CS in more ways and on large scales.
The first appointment with a nephrologist: Brazilian patients’ demographic and kidney function characteristics. A retrospective study

ABSTRACT BACKGROUND: The number of nephrologists has risen slowly, compared with the prevalence of chronic kidney disease (CKD) in Brazil. Data on patients referred to nephrology outpatient clinics remains scarce. OBJECTIVE: To determine the demographic and kidney function characteristics of patients at their first appointment with a nephrologist. DESIGN AND SETTING: Retrospective study conducted at three nephrology outpatient clinics (public and private services), in São Paulo, Brazil. METHODS: From December 2019 to February 2020, we collected patient data regarding demographics, kidney function parameters and comorbidities. We then analyzed data on 394 patients who met a nephrologist for their first appointment. RESULTS: The main comorbidities were hypertension (63.7%), diabetes (33.5%) and nephrolithiasis (22.3%). Regarding CKD stages, 24.1%, 9.1%, 13.7%, 15.2%, 15.2% and 2.3% of the patients were in stages 1, 2, 3a, 3b, 4 and 5, respectively. Proteinuria was absent or mild, moderate and high in 17.3%, 15.2% and 11.7%, respectively; and 16.2% had not undergone previous investigation of serum creatinine or proteinuria (55.8%). For 17.5%, referral to a nephrologist occurred late. Patients in public services were older than those in private services (59 years versus 51 years, respectively; P = 0.001), more frequently hypertensive (69.7% versus 57.5%; P = 0.01) and reached a nephrologist later (22.4% versus 12.4%; P = 0.009). CONCLUSION: Referrals to a nephrologist were not being made using any guidelines for CKD risk and many cases could have been managed within primary care. Late referral to a nephrologist happened in one-fifth of the cases and more frequently in the public service.
