Cyber-physical systems design for runtime trustworthiness maintenance supported by tools

The trustworthiness of cyber-physical systems is a critical factor for establishing wide-spread adoption of these systems. Hence, especially the behavior of safety-critical software components needs to be monitored and managed during system operation. Runtime trustworthiness maintenance should be planned and prepared in early requirements and design phases. This involves the identification of threats that may occur and affect user’s trust at runtime, as well as related controls that can be executed to mitigate the threats. Furthermore, observable and measureable system quality properties have to be identified as indicators of threats, and interfaces for reporting these properties as well as for executing controls have to be designed and implemented. This paper presents a process model for preparing and designing systems for runtime trustworthiness maintenance, which is supported by several tools that facilitate the tasks to be performed by requirements engineers and system designer

To Affinity and Beyond: Interactive Digital Humans as a Human Computer Interface

The field of human computer interaction is increasingly exploring the use of more natural, human-like user interfaces to build intelligent agents to aid in everyday life. This is coupled with a move to people using ever more realistic avatars to represent themselves in their digital lives. As the ability to produce emotionally engaging digital human representations is only just now becoming technically possible, there is little research into how to approach such tasks. This is due to both technical complexity and operational implementation cost. This is now changing as we are at a nexus point with new approaches, faster graphics processing and enabling new technologies in machine learning and computer vision becoming available. I articulate the issues required for such digital humans to be considered successfully located on the other side of the phenomenon known as the Uncanny Valley. My results show that a complex mix of perceived and contextual aspects affect the sense making on digital humans and highlights previously undocumented effects of interactivity on the affinity. Users are willing to accept digital humans as a new form of user interface and they react to them emotionally in previously unanticipated ways. My research shows that it is possible to build an effective interactive digital human that crosses the Uncanny Valley. I directly explore what is required to build a visually realistic digital human as a primary research question and I explore if such a realistic face provides sufficient benefit to justify the challenges involved in building it. I conducted a Delphi study to inform the research approaches and then produced a complex digital human character based on these insights. This interactive and realistic digital human avatar represents a major technical undertaking involving multiple teams around the world. Finally, I explored a framework for examining the ethical implications and signpost future research areas

A Study on Sustainability of Payment Banks in India using Technology Acceptance Model

Payment banks are new era banks that provide limited services but with simple access. The Reserve Bank of India established it with an aim to offer remittance services to migrant labor workforce, low-income households, small businesses, and other unorganized sector entities. Awareness plays a major role in the mindset of the people towards the digitalized mode of the payment system. Payment banks are currently facing many challenges as they are not allowed to lend money. Their major source of income comes only from the interest of the government securities in which they can invest. Despite all these, payment banks are struggling with huge losses and their existence is in a dubious situation. Six out of eleven payment banks are assessing the option of converting themselves into a small finance bank. In this context, the study focusses to analyze the key factors contributing to sustainability of the of payment banks. A measure of the trust and its role was used to test the relationship along with perceived usefulness and perceived ease of use. Actual usage was observed as a perception of usefulness and ease of use among the respondents. Payment banks offer a paradigm shift in making India a digital economy

Coping Methods of Caregivers Dealing with Patients Suffering from Geriatric Dementia

Dementia is a neurological disorder primarily diagnosed in the geriatric population. A problem for paid caregivers of patients diagnosed with stage-4 dementia is that they may experience caregiving stress while rendering care. However, there was no research that described the lived experiences of paid caregivers. Caregiving stress can be accompanied by behaviors or comorbid conditions and specific symptoms of stress can have a differential wellness impact. This phenomenological study explored the lived experiences of paid caregivers of patients with dementia through Vroom\u27s expectancy theory. Data were gathered through interpretative interviews from a sample of 10 to 15 purposefully selected nursing home paid caregivers. Research questions on the lived experiences and perceptions of caregivers when experiencing stress working with stage-4 dementia patients were explored. Responses to the open-ended questions were recorded and themes emerging from the interview questions were developed. Findings indicated that caregivers cope with their stress in part by coping with challenging patients through empathizing and being ready for anything. Results further showed that caregivers cope with stress by briefly withdrawing from the stress trigger, either physically or mentally. Caregiver stress can be reduced, and health maintained by other caregivers who learn from the coping methods of caregivers involved within this study

Security and Privacy Issues of Big Data

This chapter revises the most important aspects in how computing infrastructures should be configured and intelligently managed to fulfill the most notably security aspects required by Big Data applications. One of them is privacy. It is a pertinent aspect to be addressed because users share more and more personal data and content through their devices and computers to social networks and public clouds. So, a secure framework to social networks is a very hot topic research. This last topic is addressed in one of the two sections of the current chapter with case studies. In addition, the traditional mechanisms to support security such as firewalls and demilitarized zones are not suitable to be applied in computing systems to support Big Data. SDN is an emergent management solution that could become a convenient mechanism to implement security in Big Data systems, as we show through a second case study at the end of the chapter. This also discusses current relevant work and identifies open issues.Comment: In book Handbook of Research on Trends and Future Directions in Big Data and Web Intelligence, IGI Global, 201

African American Women’s Experiences of Parental Discipline Post Residential Substance Abuse Treatment

Substance use amongst African American mothers has been linked to a number of adverse effects in parental practices, including higher levels of maltreatment, strained family dynamics, delays with the child’s development, and harsh forms of discipline. There is an abundance of literature on how parenting styles affect children, yet little is known about the influence of parental discipline post discharge from a substance use residential treatment facility, specifically among African American mothers. Examining the impact of substance use on African American mothers’ parenting is important as experts in the field such as behavioral health therapists can tailor therapeutic interventions to improve their parenting skills after discharge from treatment to maintain sobriety. Guided by social cognitive theory, the purpose of this generic qualitative study was to explore the lived experiences of African American women post treatment from a residential facility who completed parenting classes and the outcome of implementing learned discipline practices. Experiential anecdotes of data collected from semistructured interviews with eight participants were hand coded for emergent themes; analysis generated four essential themes and 10 subthemes of experience. This study’s implications for positive social change include contributing to the knowledge base about the process of amending parental discipline experienced by African American mothers who completed substance use treatment at a residential facility. Findings may improve support services to prevent adverse long-term effects of substance use, develop culturally relevant interventions, and promote resilience to avoid relapse

Opening the Black Box: Explaining the Process of Basing a Health Recommender System on the I-Change Behavioral Change Model

Recommender systems are gaining traction in healthcare because they can tailor recommendations based on users' feedback concerning their appreciation of previous health-related messages. However, recommender systems are often not grounded in behavioral change theories, which may further increase the effectiveness of their recommendations. This paper's objective is to describe principles for designing and developing a health recommender system grounded in the I-Change behavioral change model that shall be implemented through a mobile app for a smoking cessation support clinical trial. We built upon an existing smoking cessation health recommender system that delivered motivational messages through a mobile app. A group of experts assessed how the system may be improved to address the behavioral change determinants of the I-Change behavioral change model. The resulting system features a hybrid recommender algorithm for computer tailoring smoking cessation messages. A total of 331 different motivational messages were designed using 10 health communication methods. The algorithm was designed to match 58 message characteristics to each user pro le by following the principles of the I-Change model and maintaining the bene ts of the recommender system algorithms. The mobile app resulted in a streamlined version that aimed to improve the user experience, and this system's design bridges the gap between health recommender systems and the use of behavioral change theories. This article presents a novel approach integrating recommender system technology, health behavior technology, and computer-tailored technology. Future researchers will be able to build upon the principles applied in this case study.European Union's Horizon 2020 Research and Innovation Programme under Grant 68112

Successful Billing Strategies in the Hospital Industry

Failure to collect reimbursement because of changing regulations negatively impacts hospital profitability. A multiple case study approach was used to explore the successful strategies billing managers employed to collect reimbursement for all legitimate Medicare claims. The target population for this study included 5 hospital billing managers from 3 organizations in the Northern New Jersey region. The complexity theory was used as a framework for assessing changing Medicare regulations and how the managers adapted to them. The data collection process for this study involved gathering data from participant interviews, documentation from the organizations of the participants, and government documented regulations and manuals. The logical and sequential order of data analysis for this study embraced Yin\u27s 5-steps data analysis that includes compiling data, disassembling data, reassembling data, interpreting the data, and concluding. The successful strategies billing managers used that emerged as themes were remaining up to date with Medicare changing compliance regulations; enhancing communication with staff, multiple departments, and Medicare; and adopting a robust billing system and other systems that compliment billing. The implications of this study for social change include the potential to ensure access to patient care for benefiting families and communities through the sharing of successful strategies for Medicare claims

Strategies to revitalize immunization service provision in urban settings of Ethiopia

AbstractBackground: Improving routine immunization in the urban population is an essential element to address immunization coverage and equity. In rural areas, deliberate efforts are made to reach the populations using adapted strategies such as outreaches while specificities of urban populations are generally not considered in immunization programs of Ethiopia.Aim: To explore the barriers and alternative strategies for immunization service provision in urban settings of Ethiopia.Methods: A qualitative study with a phenomenological study design was conducted in selected cities of Addis Ababa, Dire Dawa and Mekele from June to August 2020. Data was collected at different levels of the health system and the community by using a piloted interview guide. Thirty-five key informants and nine in-depth interviews were conducted. Audio-records of interviews were transcribed verbatim, coded and thematic analysis was performed using Open code version 4.02. software.Results: Our finding revealed that the routine immunization service provision strategy in Addis Ababa, Dire Dawa and Mekele cities was a static approach. Service inaccessibility, poor defaulter tracking mechanisms, substandard service in private facilities, shortage of supplies, and lack of training were the main barriers. We explored alternative strategies to revitalize the Expanded Program on Immunization (EPI) including, expanding services to marginalized populations, outreach/home to home service provision, expanding services to private health facilities, and inter-facility linkage through digitalization.Conclusions: The existing immunization service provision strategies in urban settings are not adequate to reach all children. Immunization service inaccessibility and substandard services were the main barriers hindering service provision. Program managers should expand routine service access to marginalized populations through outreach services, by strengthening the public-private partnership, and integrating technological innovations (like digitalization of the EPI program and application of mHealth reminders) to facilitate inter-facility linkage.
