Mover

Human mobility models typically produce mobility data to capture human mobility patterns individually or collectively based on real-world observations or assumptions, which are essential for many use cases in research and practice, e.g., mobile networking, autonomous driving, urban planning, and epidemic control. However, most existing mobility models suffer from practical issues like unknown accuracy and uncertain parameters in new use cases because they are normally designed and verified based on a particular use case (e.g., mobile phones, taxis, or mobile payments). This causes significant challenges for researchers when they try to select a representative human mobility model with appropriate parameters for new use cases. In this paper, we introduce a MObility VERification framework called MOVER to systematically measure the performance of a set of representative mobility models including both theoretical and empirical models based on a diverse set of use cases with various measures. Based on a taxonomy built upon spatial granularity and temporal continuity, we selected four representative mobility use cases (e.g., the vehicle tracking system, the camera-based system, the mobile payment system, and the cellular network system) to verify the generalizability of the state-of-the-art human mobility models. MOVER methodically characterizes the accuracy of five different mobility models in these four use cases based on a comprehensive set of mobility measures and provide two key lessons learned: (i) For the collective level measures, the finer spatial granularity of the user cases, the better generalization of the theoretical models; (ii) For the individual-level measures, the lower periodic temporal continuity of the user cases, the theoretical models typically generalize better than the empirical models. The verification results can help the research community to select appropriate mobility models and parameters in different use cases.
ChestLive

Voice-based authentication is prevalent on smart devices to verify the legitimacy of users, but is vulnerable to replay attacks. In this paper, we propose to leverage the distinctive chest motions during speaking to establish a secure multi-factor authentication system, named ChestLive. Compared with other biometric-based authentication systems, ChestLive does not require users to remember any complicated information (e.g., hand gestures, doodles) and the working distance is much longer (30cm). We use acoustic sensing to monitor chest motions with a built-in speaker and microphone on smartphones. To obtain fine-grained chest motion signals during speaking for reliable user authentication, we derive Channel Energy (CE) of acoustic signals to capture the chest movement, and then remove the static and non-static interference from the aggregated CE signals. Representative features are extracted from the correlation between voice signal and corresponding chest motion signal. Unlike learning-based image or speech recognition models with millions of available training samples, our system needs to deal with a limited number of samples from legitimate users during enrollment. To address this problem, we resort to meta-learning, which initializes a general model with good generalization property that can be quickly fine-tuned to identify a new user. We implement ChestLive as an application and evaluate its performance in the wild with 61 volunteers using their smartphones. Experiment results show that ChestLive achieves an authentication accuracy of 98.31% and less than 2% of false accept rate against replay attacks and impersonation attacks. We also validate that ChestLive is robust to various factors, including training set size, distance, angle, posture, phone models, and environment noises.

Investment Behavior and Trade Returns of Individual Investor: Mediating Role if Financial Literacy

The main objective of current study was to analyze the impact of representativeness and anchoring on the trade returns of individual investors with the mediating role of financial literacy. In this connection hypotheses were developed on the basis of behavioral finance literature. The data was collected on 5-point likert scale questionnaires which were adopted from various authors. The collected data was checked for reliability and correlation analysis and regression models were run. On the basis of results obtained from analysis the four hypotheses which were developed have been accepted. It was concluded that representativeness and anchoring has significant positive impact while the financial literacy has mediating impact on the trade returns of investors. It is recommended that more the financial literacy less risk of behavioral biases impact on investment thus investors should gain financial literacy for taking rational investment decision and good trade returns.
Contribution of Precision Livestock Farming Systems to the Improvement of Welfare Status and Productivity of Dairy Animals

Although the effects of human–dairy cattle interaction have been extensively examined, data concerning small ruminants are scarce. The present review article aims at highlighting the effects of management practices on the productivity, physiology and behaviour of dairy animals. In general, aversive handling is associated with a milk yield reduction and welfare impairment. Precision livestock farming systems have therefore been applied and have rapidly changed the management process with the introduction of technological and computer innovations that contribute to the minimization of animal disturbances, the promotion of good practices and the maintenance of cattle’s welfare status and milk production and farms’ sustainability and competitiveness at high levels. However, although dairy farmers acknowledge the advantages deriving from the application of precision livestock farming advancements, a reluctance concerning their regular application to small ruminants is observed, due to economic and cultural constraints and poor technological infrastructures. As a result, targeted intervention training programmes are also necessary in order to improve the efficacy and efficiency of handling, especially of small ruminants.
Wideband‐integrated planar inverted‐F antenna with meander line structures

An improved wideband planar inverted‐F antenna (PIFA) is investigated in this work. The meander line structure is introduced into the conventional PIFA and significant bandwidth improvement can be observed. Two improved PIFA antennas with different meander line structures are designed and fabricated; the measured results show good agreement with the simulations, demonstrating 23.1 and 40% bandwidth at −10 dB return loss, about 131 and 300% bandwidth enhancement, respectively, compared with the original PIFA (less than 10%). Obviously, the proposed antenna demonstrates good performances (especially in bandwidth), compact size, low profile, and low cost; it is thus expected to find possible applications in wireless communication systems. © 2008 Wiley Periodicals, Inc.

The Security File System in Smart TV Operating System

Modern smart TV devices have put a wealth of information and ever increasing opportunities for social interaction at the fingertips of users. At the center of this revolution are smart phone, smart TV and tablet computers, which give people a nearly constant connection to the Internet. As smart TV usage increases, more developers become involved in implementing application for smart TV. Security for application running on the smart TV is important. The smart TV operating system provides great flexibility not only for application developers but also for users. Most of Smart TV Operating Systems are open source operating system designed for Digital TV available on a variety of smart TV devices. As with PCs, there are a variety of security threats that can affect the smart TV device such as application based threat, web based threat, network based threat and file data threat. In this paper, we mainly focus on file data threat, in order to keep the data integrity the information should not be amended, damaged and loss in transmission process. We present the security file system in the Smart TV Operating System.
The role of leaders' paradigm in construction industry change

As in other industries, firms in the construction industry need to become more client‐ and market‐oriented. In the last decade, several initiatives have been taken to change the construction industry in that direction. The changes, however, seem to be slower than other industries and less forthcoming than projected. Old practices and patterns die hard. Fundamental changes in orientation, strategy and strategy deployment require shifts in the management paradigms (i.e. the ‘frames of mind’ that steer individual and collective behaviour). Management is seen as a crucial factor in these change processes, but can the new business be created by old management paradigms? Can the leaders in the construction industry shake off the old paradigms? An explorative quantitative study shows that the mainstream paradigm of construction industry leaders today is much as it was in the past: technology‐ and project‐oriented. Acting out of this paradigm, issues as social‐organizational change and strategic focus on the client – regarded as important for the industry – will probably not be addressed properly. Change initiatives could gain in success, when they create wider awareness of existence and persistence of incumbent and prevailing paradigms.
A Study on the Medication Errors in the Administration of N-Acetylcysteine for Paracetamol Overdose Patients in Malaysia

Introduction N-Acetylcysteine (NAC) has been used to treat paracetamol overdose for four decades. But the administration of NAC regimens is complicated. Therefore, medication errors are an ongoing issue in the acute-care setting and directly impact the safety of patients. Objective To evaluate the rate of NAC-related medication errors during the management of paracetamol overdose at a teaching hospital in Malaysia. Methods This clinical audit study was performed retrospectively between June 2008 and June 2011. Patients who presented to the adult emergency department with paracetamol overdose and had received at least the loading dose of intravenous NAC were eligible. Children below the age of 12 years old were not included. Also, patients displaying chronic excessive paracetamol usage or recurrent paracetamol overdose were excluded. We determined the type and frequency of medication errors during intravenous NAC administration. Results The study population ranged from 13 to 87 years old (mean age: 25.06; median: 23) and was predominantly female. The overall prevalence of intravenous NAC-related medication errors was found to be 84.3%. Moreover, the following frequencies were observed based on error type: 5.9% wrong dose, 37.3% incorrect infusion rate, 8.5% interruption during treatment, and 66.5% unnecessary administration. Conclusion We observe a surprisingly high prevalence of medication errors related to the administration of intravenous NAC. Thus, this emerging issue needs be addressed in order to ensure patient safety as well as to prevent unnecessary hospital admissions and/or burdening treatment costs.

Mimicking DNA Functions with Abiotic, Sequence-Defined Polymers

Abstract Advances in synthetic chemistry have enabled abiotic, sequence defined polymers to imitate the structures and functions once exclusive to DNA. Indeed, the vast library of accessible backbones and pendant-group functionalities afford synthetic polymers an advantage over DNA in emerging applications as they can be tailored for stability or performance. Moreover, novel methodologies for sequencing and conjugation have been leveraged to elevate the versatility of discrete macromolecules. This review highlights abiotic, sequence-defined polymers in their capacity to mimic the primary functions of DNA – data storage and retrieval, sequence-specific self-assembly of duplexes, and replication and synthetic templating of new macromolecules.
Medication compliance in schizophrenic out patients with psychoactive substance use co-morbidity: a cross-sectional study

Background: Medication adherence is an important issue in the treatment and management of persons with psychiatric disorders including schizophrenia. Apart from side effects and inefficient outcomes of psychiatric medications, substance abuse also complicates the adherence pattern to the prescribed medications. Present study was designed to estimate the magnitude of medication non-adherence and its correlates in patients with schizophrenia having co-morbid psychoactive substance use.Method: The 60 schizophrenic patients with active substance use were taken from OPD of institute of mental health and hospital, Agra. Positive and negative syndrome scale (PANSS), alcohol, smoking and substance involvement screening test (ASSIST), medication adherence rating scale (MARS) and Morisky 8-item medication adherence questionnaire (MMAQ-8) were used to gather relevant clinical data along with a proforma for recording socio-demographic characteristics.Results: The results revealed an alarming level of medication adherence. The 91.7% sample (55 patients) met the criteria for medication non-adherence. Majority of the patients were using alcohol (58.3%) and cannabis (51.7%). Conclusions: Given the high rate of medication non-compliance it is suggested that specific intervention aimed at compliance to prescribed medication is needed in this population.

Modeling the value of remanufacture in an integrated manufacturing-remanufacturing organization

In recent years, the concept of reusing products has received significant attention in academia as a means for reducing society’s negative impact on the environment. In fact, due to a number of both economic and environmental advantages to product reuse, some authors have proposed a larger role for reuse within society. In order to achieve an expanded role for product reuse, it will first be necessary to integrate remanufacturing capabilities into original equipment manufacturers (OEMs) such that reuse can be carefully planned by both product and process design. However, the implementation of OEM reuse is currently limited to the few examples that exist today by several barriers. These barriers include the problem of incomplete incentives due to the product disposal externality, the trends in production towards rapid innovation and mass customization, and the fact that remanufacture presents a fundamentally new set of challenges that producers are not prepared to deal with. It is our belief that reuse will not play a larger role in society until producers have both the incentives and ability to implement remanufacture given their business conditions. Providing this capability and these incentives will require a better understanding of how different factors impact remanufacturing operations within an OEM. This understanding can be provided through the improved modeling of remanufacture. In this work, a motivation and an algorithm for modeling how product design characteristics, product development strategies, and different business conditions impact remanufacturing viability is presented. The authors’ implementation of this model is described and the model is used to study a family of single use camera products over an eleven-year period in order to gain insight from a successful OEM remanufacturer.
Societal-Equity-Enhancing Criteria and Facility-Host Incentives Supporting Five Key Elements in the January 2012 Blue Ribbon Commission Report - 13015

In February 2009, the Obama Administration announced it would abandon USA’s only candidate SNF/HLW-disposal facility since 1987. In 2010, all related activities were stopped and the Blue Ribbon Commission on America’s Nuclear Future was established “to recommend a new strategy for managing the back end of the nuclear fuel cycle”, which it did in January 2012, emphasizing eight key elements. However, Key Element 1, “A new, consent-based approach to siting future nuclear facilities”, is qualitative/indeterminate rather than quantitative/measurable. It is thus highly-susceptible to semantic permutations that could extend rather than, as intended, expedite the siting of future nuclear facilities unless it also defines: a) Whose consent is needed? ; and b) What constitutes consent? The following “generic”, radiation-risk- and societal-equity-based criteria address these questions: 1. Identify areas affected by projected radiation and other health risks from: a. The proposed nuclear facility (facility stakeholders); and b. The related nuclear-materials-transportation routes (transportation stakeholders); then 2. Surround each stakeholder area with a buffer zone and use this enlarged foot print to identify: a. Stakeholder hosts; and b. Areas not hosting any stakeholder category (interested parties). 3. Define “consent-based” as being at least 60 percent of the “population” in the respective stakeholder category and apply this yardstick to both “in favor” and “against” votes. Although criteria 1 and 2 also need facility-based definitions to make Key Element 1 measurable, the described siting approach, augmented by related facility-host incentives, would expedite the schedule and reduce the cost for achieving Key Elements 4-6 and 8, politics permitting.
P16 expression and clinicopathological features of oral and oropharyngeal squamous cell carcinoma

Background: There is an epidemiological shift in head and neck squamous cell carcinoma (HNSCC) attributable to HPV infection. HPV positive HNSCC has unique biology, risk factors, clinicopathological characteristics and outcome. There is a large variation in the published prevalence of HPV-related HNSCCs in India ranging from 7 to 78.7%. This study aims to find the P16 expression in the oral cavity and oropharyngeal SCC, thereby prevalence of HPV in our setting and to define the clinicopathological characteristics of HPV positive tumours in our setting.Methods: 210 specimens of primary Oral squamous cell carcinoma (OSCC) and Oropharyngeal Squamous cell carcinoma (OPSCC) were included. Immunohistochemistry was done using monoclonal mouse p16 antibody. Clinical details of each case were collected. Analysis was done using SPSS software and the association of P16 and clinicopathological variables were calculated using Fishers exact test.Results: P16 positive expression is observed only in 1/122 (0.82%) of OSCC and 8/88 (9%) of OPSCC. P16 positivity showed significant association with Grade of tumor (p= 0.008) and histological variant of SCC (p=0.00). 77.7% of P16 positive tumours are Grade 2 and 66.6% of Basaloid SCC was P16 positive. There is no significant association between p16 expression and other variables (subsite, age, gender, alcoholism, smoking, betel chewing and stage). Conclusions: P16 positivity was higher in oropharyngeal than in oral cancer. However, the HPV positivity rates are lower than other parts of India.
Role of Diversity in Enhancing Cognitive Learning and Performance

N. Ravichandran Faculty member, Jamia Hamdard, New Delhi drnrav@gmail.com DoI: 10.23862/kiit-parikalpana/2021/v17/i2/210547 both are working towards improving its constituent. This includes making policies and programs that are essential to attain and retain the most competent human resources. Hence, managing a diverse workforce has become one of the biggest HRM challenges to survive in the neck to neck competition. The organizations that except new challenges and are ready with new plans and policies have more chances to get a competitive advantage (Eugene Chew Weiliang, 2011). With the retention of skilled workers, workplaces have become more diverse in terms of capabilities, knowledge, and behavior. The purpose of the study is to analyze the key factors with respect to the organizations’ progress towards better sustainability. The study also attempts to study the association between diversity acceptance and cognitive learning. The paper contributes to the emerging literature linking diversity and cognitive learning.
