A Comprehensive Study on Privacy and Security on Social Media

In many aspects of healthy, science, educational, functional, and social life, social media networks today are part of the human lifestyle. Social media has more impact on human life and introduced significant changes in the way people’s way of communication. People exchange a lot of information across social media networks, starting with the sharing of information with the growth of information sharing at the moment, and the advancement of technology Users create overt networks to reflect their current or new social connections. Users also upload and post a plethora of personal details. Maintaining the privacy and security of the user is a main challenge in social media. Users should feel the importance of preserving the privacy of their data and how valuable information such as banking details and confidential data should be kept away from social media. Users can also post personal information about others without their permission. The problem is exacerbated by users' lack of familiarity and knowledge, as well as the lack of appropriate resources and architecture of social media networks. This paper provides study on many privacy and security challenges encountered by social media networks and the privacy threats they pose, as well as current studies into possible solutions.
Cascaded Multi-Level Inverter Based IPT Systems for High Power Applications

A single phase H-bridge inverter is employed in conventional Inductive Power Transfer (IPT) systems as the primary side power supply. These systems may not be suitable for some high power applications, due to the constraints of the power electronic devices and the cost. A high-frequency cascaded multi-level inverter employed in IPT systems, which is suitable for high power applications, is presented in this paper. The Phase Shift Pulse Width Modulation (PS-PWM) method is proposed to realize power regulation and selective harmonic elimination. Explicit solutions against phase shift angle and pulse width are given according to the constraints of the selective harmonic elimination equation and the required voltage to avoid solving non-linear transcendental equations. The validity of the proposed control approach is verified by the experimental results obtained with a 2kW prototype system. This approach is expected to be useful for high power IPT applications, and the output power of each H-bridge unit is identical by the proposed approach.
STUDYING EMBODIED INTERACTION WITH THE DESIGN ENVIRONMENT: WHAT IS THE ROLE OF PRESENCE IN DESIGN?

This study characterizes the changes in designer's perception of space and interaction within the design environment while they are moving from sketching to non-immersive to immersive 3D designing. The designer's actions and speech are videotaped and analyzed using protocol analysis method. The analysis of the protocols shows that the types of representation afford different perceptual focus on the spatial properties of the design solution. This finding indicates that the designers developed a sense of presence in the the 3D immersive VE that have an impact on visuo-spatial reasoning.
Resource Allocation and Task Scheduling in Fog Computing and Internet of Everything Environments: A Taxonomy, Review, and Future Directions

The Internet of Everything paradigm is being rapidly adopted in developing applications for different domains like smart agriculture, smart city, big data streaming, and so on. These IoE applications are leveraging cloud computing resources for execution. Fog computing, which emerged as an extension of cloud computing, supports mobility, heterogeneity, geographical distribution, context awareness, and services such as storage, processing, networking, and analytics on nearby fog nodes. The resource-limited, heterogeneous, dynamic, and uncertain fog environment makes task scheduling a great challenge that needs to be investigated. The article is motivated by this consideration and presents a systematic, comprehensive, and detailed comparative study by discussing the merits and demerits of different scheduling algorithms, focused optimization metrics, and evaluation tools in the fog computing and IoE environment. The goal of this survey article is fivefold. First, we review the fog computing and IoE paradigms. Second, we delineate the optimization metric engaged with fog computing and IoE environment. Third, we review, classify, and compare existing scheduling algorithms dealing with fog computing and IoE environment paradigms by leveraging some examples. Fourth, we rationalize the scheduling algorithms and point out the lesson learned from the survey. Fifth, we discuss the open issues and future research directions to improve scheduling in fog computing and the IoE environment.
MAGECally invert images for realistic editing

Generative Adversarial Networks (GANs) are now able to generate astonishingly realistic high-resolution images. Recent work has shown the emergence of semantically-meaningful manipulations simply by editing the corresponding latent vector. However, a real image must ﬁrst be inverted into its GAN latent code before editing. Previous work usually achieves accurate reconstruction, but poor-quality latent vectors: applying known editing methods onto these latent codes results in artifacts and erroneous edits. We aim to bridge the gap between reconstruction and editability. We propose a novel instance-optimization based inversion method, which speciﬁcally aims to maximize the semantic information of the latent vector, all while producing an accurate reconstruction. We introduce the i MAG e-lat E nt C onsistency loss (“MAGEC”), which allows supervision in the latent space, encouraging editability of the resulting latent vector. We provide extensive qualitative and quantitative evaluation to validate our method, using the recent state-of-the-art StyleGAN and show that our method outperforms baseline inversion methods, opening the door to new realms of real-image editing.
Next Release Optimization Problem Using Multi-Objective Harris Hawks Optimization Algorithm

Companies that maintain large and complex software systems are usually facing Next Release Problem (NRP) in determining what requirements and features should be implemented in the next release [4]. Usually, there is a budget for software development, and there is a lot of requirements to be implemented. In this dilemma, the companies must satisfy customers’ requests without exceeding the development budget limit. In such a problem, requirement selection depends on the value, integrity, and dependencies between requirements. In this thesis, a new approach is proposed to tackle NRP. One of the recent Swarm Intelligent (SI) Meta Heuristics algorithms is used to tackle NRP, which is "Harris Hawks Optimization (HHO)" [24]. This algorithm is converted from a Single-Objective to Multi-Objective using two fitness functions, then used to find the best set of requirements that achieve customers’ satisfaction within the development budget. Different datasets from related NRP literature are used to assess the proposed approach’s performance. It contains classic and real instances. Classic datasets were generated in labs to be used for experiments. The realistic datasets were derived from a real open source project. Both types include requirements cost, requirements requested by each customer, and the profit will be gained for implementing customer requirements.
Perceived Associations between Excessive Sugar Intake and Health Conditions

Excessive sugar intake represents an increased risk of developing non-communicable diseases (e.g., obesity, cardiometabolic diseases, and dental diseases). Still, it is unclear whether people are aware of these adverse health outcomes. The current study systematically examined the extent to which people associate health conditions with excessive sugar intake. Participants (N = 1010 Portuguese volunteers) freely reported all health conditions they associated with excessive sugar consumption and rated the strength of these associations for eight specific health conditions. All participants reported health conditions associated with excessive sugar intake, with the most frequent being risk factors for cardiometabolic diseases (e.g., diabetes), cardiovascular diseases, oral problems, oncological and mental health conditions. Moreover, participants considered diabetes, overweight/obesity, and oral problems as being the conditions most related to excessive sugar intake. Women, participants with children in the household, and experts in health/nutrition rated excessive sugar intake as being more strongly linked to some of the health conditions. The identification of the health conditions that people associate with excessive sugar consumption may inform policymakers, educators, and health professionals and support interventions targeting the general public or specific groups (e.g., overweight people) in raising awareness of potential adverse health outcomes and, ultimately, contribute to reducing sugar intake.

Bank competition, interest rate pass-through and the impact of the global financial crisis: evidence from Hong Kong and Macao

PurposeThe authors examine the interest rate pass-through in Hong Kong (HK) and Macao both in the long term and short term.Design/methodology/approachThe authors use time series methodology, i.e. unit root, cointegration and error correction models.FindingsThe results show that in the post-global financial crisis (GFC) period, both the long-run and short-run interest rate pass-through from policy rates to prime rates have disappeared in Macao and are weakened significantly in Hong Kong. The long-term relationship between deposit rates and policy rates no longer exists in either market while the short-term relationship has been reduced significantly.Research limitations/implicationsThe results indicate that the effectiveness of monetary policy in HK and Macao has been seriously undermined in the post-GFC period. New tools are needed in both regions.Practical implicationsMonetary policy transmission via bank interest rates in both HK and Macao are no longer effective after the outbreak of the GFC.Social implicationsEffort to stimulate the economy and/or control inflation will be hampered.Originality/valueTo the best of the authors’ knowledge, this is the first study to examine the impact of the GFC on the effectiveness of monetary policy transmission in HK and Macao.
The Cutoff Value and Prognosis of Anti-PLA2R for Idiopathic Membranous Nephropathy: A Single- Center Retrospective Study From China

Background：Analyzing the antibody level of anti-phospholipase A2 receptor (anti-PLA2R) with idiopathic membrane nephropathy (IMN) and its correlation with clinical parameters and prognosis, and to explore optimal cut-off value for Chinese patients. Methods All hospitalized patients with renal biopsy from April 2017 to November 2019 in Peking University Third Hospital whose clinical and pathological characteristics were analyzed, and the level of serum PLA2R antibodies was detected using the method of enzyme-linked immunosorbent assay (ELISA). Result: The sensitivity, specificity, and Youden index of anti-PLA2R in the diagnosis of IMN in the Chinese patients were 85.7%, 88.3%, and 0.740 for the 2.5 RU/ml cut-off value; 77.8%, 96.0%, and 0.737 for the 6.3RU/ml cutoff value, respectively. The area under the ROC curve was 0.916. Compared with the high titer group, the low titer group had a higher serum albumin level (p=0.016), a lower cholesterol level (p=0.025) and a lower low density lipoprotein cholesterol (p=0.010). Multivariable Cox regression analysis showed that just immunosuppressive therapy (adjusted HR=4.656, 95 % CI 1.461-14.839, p=0.006) was associated with higher remission rate of IMN patients. Conclusion: The best cutoff for ELISA method to detect anti-PLA2R antibodies in IMN patients is probably much lower (around 2-7 RU/ml) than that indicated by the manufacturer. The cut-off value of 6.3 RU/ml could get a higher sensitivity and not a lower specificity. If the IMN patients were treated actively, they maybe can get better prognosis.
Animal Welfare and Parasite Infections in Organic and Conventional Dairy Farms: A Comparative Pilot Study in Central Italy

Simple Summary European sustainability-oriented policies aim to encourage organic (ORG) farming practices since they are considered to be more resilient than conventional (CONV) ones and to grant higher animal welfare standards. On the other hand, animals farmed organically are considered at higher risk of parasitic infections, since grazing could expose animals to higher parasite load. Considering the contrasting data present in literature, the present work aims to investigate and compare the animal welfare conditions and gastrointestinal distribution in ORG and CONV dairy farms in central Italy. Animals from ORG farms involved in this study presented significantly less skin damages in the rear legs than animals from CONV farms. No significant differences were found for any of the other welfare-related parameters and for parasite prevalence. Results highlight that ORG farming did not have a negative impact on animal welfare and that pasture access, provided in ORG farms, did not negatively impact parasite prevalence. Abstract The study investigated and compared welfare conditions and gastrointestinal (GI) parasites distribution among organic (ORG) and conventional (CONV) farms in central Italy. Five ORG and five CONV farms were assessed for animal welfare with an adapted version of the AssureWel protocol. Faecal samples collected from the rectum of the animals both in ORG (n = 150) and CONV (n = 150) were analysed using conventional copromiscroscopy. The presence of skin damages in the rear legs was significantly predominant (p < 0.001) in CONV (26.7%) compared with ORG farms (10.0%). No differences were found for lameness, cleanliness, Body Condition Score, hair loss, body lesions and swelling prevalence. Data concerning the productive performances, e.g., total milk, fat and protein yields standardised in mature equivalent (ME) were collected. ME milk yield (ORG: 9656.9 ± 1620.7 kg; CONV: 12,047.2 ± 2635.3) and ME fat yield (ORG: 396.6 ± 66.8; CONV: 450.3 ± 102.8) were significantly lower in ORG farms (p < 0.001). Anthelmintics were used regularly in 4/5 CONV and 0/5 ORG farms. In 2 CONV farms (40%) and 4 ORGs (80%) at least one animal tested positive for GI parasites. No significant differences in parasites prevalence emerged (ORG = 10.7%; CONV = 8%). These data indicate that ORG farming does not influence parasite prevalence and animal welfare status.
Palliative Care in Patients with Advanced Heart Failure: A Systematic Review.

INTRODUCTION Heart failure is a disease with survival estimates of around 10% after 10 years of the disease. Being a chronic and debilitatingillness, it is important to investigate the potential efficacy of a palliative care approach for these patients. The aim of this study is to systematically review the efficacy of integrating palliative care in patients with advanced heart failure, including the outcomes overall quality of life and well-being, overall symptom burden and possible specific symptoms, hospital admission rates and mortality. MATERIAL AND METHODS The MEDLINE, Cochrane, EMBASE and CINAHL databases were searched for articles published between January 2010 and December 2020 about palliative care interventions in patients with heart failure. Clinical studies with humans with symptomatic heart failure were included, comparing the integration of palliative care with usual cardiac care. RESULTS The search protocol resulted in seven eligible studies for review and qualitative synthesis. The overall risk of bias within studies was moderate to high. Most studies demonstrated improvements with the integration of palliative care in terms of quality of life and reduction of admission rates. The evidence to support a significant improvement in overall symptom burden was not so robust among studies. CONCLUSION Palliative care interventions seem, overall, to be significantly effective in patients with heart failure. Future studies with more rigorous study designs are needed, in order, to further develop the role of palliative care in heart failure patients.
A Flow Induced Vertical Thermoelectric Generator and Its Simulation Using COMSOL Multiphysics

In this study, a new thermoelectric harvester with fluid flow for increased performance. The thermoelectric generator is 3- D vertical configuration with p- and n-doped Silicon thermolegs. There is water flow between channels integrated through the thermoelectric columns, providing forced convection on the heat flow path. By this method, the temperature difference between the hot and cold junctions of the generator is highly increased, resulting in an increased voltage and power output. The Thermoelectric and Navier-Stokes equations are coupled in this work to obtain a whole performance profile of the thermoelectric energy generator.

Simulation results based on PSIM are provided to demonstrate the effectiveness of the system.
Exoticness; High-performance; and Luxury: Design of A Brand-specific Supercar Interior Using the PPE Framework

Purpose: This paper presents a design study undertaken to develop a concept motorcar interior based on the Hulme F1 supercar exterior prototype. The study focused on generating an appropriate visual design proposal with the support of the Perceptual Product Experience (PPE) framework to guide design progress and validate design work. Methodology/approach: Throughout the project, the PPE framework was used as a tool to specify, direct and evaluate design work and to support design decision making. Design research work was categorised in the stages of contextual research, contemporary design analysis, design development, and design evaluation. Evaluation was done using a small quantitative-qualitative survey with external respondents, employing VAS scales, Likert scales and open ended questions. Findings: This paper illustrates how the PPE framework can be applied as an effective tool for establishing an appropriately and creatively managed design direction during the design development process. Providing a number of benefits for design research, the framework helps position, benchmark and develop visual design characteristics within a contemporary market context. The framework also supports the development of appropriate, valid and measurable experience design criteria, which traditionally is difficult due to the subjective nature of design perception. The outcome of the external evaluation indicated that intended experiential design criteria had successfully been transformed as perceived by the respondent group. Originality/value: The structure and tools of the PPE framework to analyse, categorise, specify, direct and evaluate creative design work in an area where design work traditionally relies on intuitive and subjective approaches. This is of value for communicating, managing and direction design work on operational and strategic levels of design, and has the potential to contribute to the quality assurance of design processes.
The Systematic Workplace-Improvement Needs Generation (SWING): Verifying a Worker-Centred Tool for Identifying Necessary Workplace Improvements in a Nursing Home in Japan

This study developed and tested a new measurement instrument, the Systematic Workplace-Improvement Needs Generation (SWING), to identify workplace-improvement needs. The participants were 53 workers in a Japanese nursing home for the elderly. The respondents used the SWING questionnaire to self-generate five ‘cues’ they considered important to improve the workplace. The workers determined each cue’s sufficiency level and weight balance (importance), and then we summarised the 265 cues into 21 categories for workplace improvements. The respondents identified the following items as the most important and the least sufficiently provided areas for workplace improvement: ‘interaction with customers’, ‘physical and psychological harassment’, ‘rewarding and challenging work’, and ‘sharing goals and objectives’. Although the workplace-improvement recommendations differed greatly from person to person, SWING prioritised the items by weight (importance) and sufficiency (current status), allowing organisations to address the needed improvements systematically. The SWING tool effectively elicited and prioritised respondents’ recommendations for improving the workplace. Because its items are self-generated by the respondents, SWING can be used for any occupation or workplace. Visualisation with bubble plots to clarify the improvement needs is incorporated into SWING.
The necessity of optimal design for parallel machines and a possible certified methodology

Although they have many advantages in term of positioning accuracy, stiffness, load capacity parallel machines have also a main drawback: their performances are very sensitive to their dimensioning. Hence although the choice of a given mechanical structure among the numerous possibilities that are offered for parallel machines may influence the performances of the machine the rule of thumb is: a mechanically appropriate but poorly dimensioned machine will present in general largely lower performances than a well designed machine with a mechanical architecture a priori less adequate. Optimal dimensioning of a parallel machine is hence a critical issue but also a complex one, especially if uncertainties in the manufacturing are taken into account. We will present a possible design methodology based on interval analysis and will illustrate this methodology on realistic examples.
