This paper has been developed in the IEA SHC Task 61 Integrated Solutions for Daylighting and Electric Lighting scope. Task 61 aims at developing and testing strategies and solutions combining daylighting, electric lighting, and the most suitable control systems. Some of the planned activities, especially in the Subtask A: User perspective and requirements, were not possible due to the Coronavirus pandemic restrictions. On the other side, new challenges emerged, for example, the migration of workplaces to homes. It occurred both for professionals and students, and the lighting conditions in these new improvised workplaces are unknown. In this context, the article presents the part of the home office survey aiming to understand lighting conditions for students in home offices in different countries: Brazil, Italy, Japan, Columbia, Denmark, and Poland. The paper also seeks to define the current limitations of a home office in providing a resilient visual environment.

A measure to mitigate the spread of the COVID-19 virus during the first year of the pandemic was to stay home. Thus, working and learning activities have migrated to dwellings under the so-called home office scheme. In this context, exploring the lighting conditions in home offices from the occupant's perspective is vital for understanding the quality of the perceived visual environment at home. Based on data collected in Brazil and Colombia, this preliminary study aimed to investigate occupant’s perception of the luminous environment in home offices and the influence of regional and personal characteristics. This study is part of broader research related to Subtask A of IEA Task 61, "Integrated Solutions for Daylighting and Electric Lighting." Occupant's subjective assessments were collected from December 2020 to March 2021 through an online survey with professionals working from home. The results show that most professionals have an entire room for the home office, and these are more satisfied with the visual environment. In general, higher satisfaction was achieved when the lighting level was perceived as brighter and strong reflections were associated with disturbing glare situations. Most of the occupants perceived the light and colours as neutral. Daylight is more appreciated than artificial light. Participants located between 20°S and 34°S latitude were less satisfied with the visual environment in the home office. The first approach is part of comprehensive research, generating new data about lighting in home offices to subside guidelines for improving housing projects.

New technologies and so-called communication and information technologies are transforming our society, the way in which we relate to each other, and the way we understand the world. By a wider extension, they are also influencing the world of law. That is why technologies will have a huge impact on society in the coming years and will bring new challenges and legal challenges to the legal sector worldwide. On the other hand, the new communications era also brings many new legal issues such as those derived from e-commerce and payment services, intellectual property, or the problems derived from the use of new technologies by young people. This will undoubtedly affect the development, evolution, and understanding of law. This Special Issue has become this window into the new challenges of law in relation to new technologies.

Several methodologies in user centered research lead to the collection of large amounts of comments about a product or system. The growth of social media research has led to the development of sentiment analysis algorithms that computationally analyze the meaning of text. This paper utilized the Valence Aware Dictionary for sEntiment Reasoning (VADER) sentiment analysis technique to assess comments from a user centered design study for a rotorcraft degraded visual environment mitigation system. The sentiment analysis findings mirror results from the other measures of the user centered design study. This paper supports the use of sentiment analysis for large volumes of comment data from user centered design studies.

The equivalence of two conditions, condition (3) and condition (4) stated in Problem Statement section, regarding the existence of stabilizing switching laws between two unstable linear systems first appeared in (Feron 1996). Although Feron never published this result, it has been referenced in almost every survey on switched systems; see, for example, (Liberzon and Morse 1999). This paper proposes another way to prove the equivalence of two conditions regarding the existence of stabilizing switching laws between two unstable linear systems. One is effective for theoretical derivation, while the other is implementable, and a class of stabilizing switching laws have been explicitly constructed by Wicks et al. (1994). With the help of the equivalent relation, a condition for the existence of controllers and stabilizing switching laws between two unstabilizable linear control systems is then proposed. Then, the study is further extended to the issue concerning the construction of quadratically stabilizing switching laws among unstable linear systems and unstabilizable linear control systems. The obtained results are employed to study the existence of control laws and quadratically stabilizing switching laws within a class of unstabilizable linear control systems. The numerical examples are illustrated and simulated to show the feasibility and effectiveness of the proposed methods.

Focusing on a sample of U.S. retailers, I study the management control systems (MCS) that firms introduce when they first invest in controls, and identify four categories of initial MCS, which are defined in terms of the purposes these MCS fulfill. The first category, “Basic MCS,” is adopted to collect information for planning, setting standards, and establishing the basic operations of the firm. The other three categories are contingent on more specific purposes: “Cost MCS” focus on enhancing operating efficiencies and minimizing costs; “Revenue MCS” are introduced to foster growth and be responsive to customers; and “Risk MCS” focus on reducing risks and protecting asset integrity. I hypothesize and find that the choice among these categories reflects the firms' strategy, and that firms that choose initial MCS better suited to their strategy perform better than others.

Management control systems-strategy, performance measures, and incentives-play a vitally important role in the success or failure of organizations. As such, management control systems represent one of the foundational topics in managerial accounting. However, as the case illustrates, developing, implementing, and continuously enhancing a management control system to be effective often proves very challenging. Therefore, the case develops students' ability to critically assess the interrelationships between these three management control system elements. In particular, students are immersed into two dysfunctional management control systems-one at W. T. Grant in the 1970s and the other at Wells Fargo in the 2010s-to highlight the complexities, challenges, and power of such systems to elicit both positive and negative behavioral and decision impacts on employees, customers, regulators and, ultimately, shareholders. In so doing, the case also increases students' interest in studying managerial accounting, as well as their realization of its importance to an organization's success or failure.

Unmanned factories became a topic of discussion after the concept of Industry 4.0 was first introduced in the Hannover Fair in 2001, and increasing the computerization level in business life and supporting the production processes with advanced technology were determined as targets. In this regard, artificial intelligence and increased automation are expected to create new kinds of jobs in the coming years; however, a significant problem is predicted considering that these changes will invalidate a high number of job types exist today. Thus, the workforce will face a severe unemployment threat. As a result of all of this, radical changes in the work methods, along with means of seeking employment, are now considered. The qualities of the work and the workforce are being transformed along with the organization methods of the production. While on the other hand, it becomes evident that education also has to adapt to this transformation. In this study, the issues the labor might have to face during this period will be discussed, along with what could be done to solve these problems.

Abstract There is an ongoing scientific debate regarding the merits and shortcomings of P4 Medicine (predictive, preventive, personalized, and participatory) and O4 Medicine (overtesting, overdiagnosis, overtreatment, and overcharging). P4 Medicine promises to revolutionize scientific wellness through longitudinal big data collection, denoted as “dense phenotyping,” which could uncover early, actionable signs of disease, thus allowing earlier interventions and possible disease reversal. On the other hand, O4 Medicine draws attention to the potential side effects of P4 Medicine: overtesting, overdiagnosis, overtreatment, and overcharging fees. Preliminary data from the P4 Medicine concept have been recently published. A novel biotechnology company, Arivale, provided customers with services based on P4 Medicine principles; however it could not sustain its operations and closed its doors in April 2019. In this report, we provide our own insights as to why Arivale failed. While we do not discount that in the future, improved testing strategies may provide a path to better health, we suggest that until the evidence is provided, selling of such products to the public, especially through the “direct to consumer” approach, should be discouraged. We hope that our analysis will provide useful information for the burgeoning fields of personalized medicine, preventive medicine, and direct to consumer health testing.

Humans have the capability to flexibly adapt to visual stimulation, such as spatial inversion in which a person wears glasses that display images upside down for long periods of time (Ewert, 1930; Snyder and Pronko, 1952; Stratton, 1887). To investigate feasibility of extension of vision and the flexible adaptation of the human visual system with binocular rivalry, we developed a system that provides a human user with the artificial oculomotor ability to control their eyes independently for arbitrary directions, and we named the system Virtual Chameleon having to do with Chameleons (Mizuno et al., 2010, 2011). The successful users of the system were able to actively control visual axes by manipulating 3D sensors held by their both hands, to watch independent fields of view presented to the left and right eyes, and to look around as chameleons do. Although it was thought that those independent fields of view provided to the user were formed by eye movements control corresponding to pursuit movements on human, the system did not have control systems to perform saccadic movements and compensatory movements as numerous animals including human do. Fluctuations in dominance and suppression with binocular rivalry are irregular, but it is possible to bias these fluctuations by boosting the strength of one rival image over the other (Blake and Logothetis, 2002). It was assumed that visual stimuli induced by various eye movements affect predominance. Therefore, in this research, we focused on influenced of patterns of eye movements on visual perception with binocular rivalry, and implemented functions to produce saccadic movements in Virtual Chameleon.
