A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task prioritization in multitasking or multiprogramming environments. All operations must verifiably complete within given time and resource constraints or else fail safe. Real-time operating systems are event-driven and preemptive, meaning the OS can monitor the relevant priority of competing tasks, and make changes to the task priority. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts.
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip may require the bundling of services provided by several firms, agencies and modes.
In economics, a public good is a good that is both non-excludable and non-rivalrous. Use by one person neither prevents access by other people, nor does it reduce availability to others. Therefore, the good can be used simultaneously by more than one person. This is in contrast to a common good, such as wild fish stocks in the ocean, which is non-excludable but rivalrous to a certain degree. If too many fish were harvested, the stocks would deplete, limiting the access of fish for others. A public good must be valuable to more than one user, otherwise, its simultaneous availability to more than one person would be economically irrelevant.
Feminist economics is the critical study of economics and economies, with a focus on gender-aware and inclusive economic inquiry and policy analysis. Feminist economic researchers include academics, activists, policy theorists, and practitioners. Much feminist economic research focuses on topics that have been neglected in the field, such as care work, intimate partner violence, or on economic theories which could be improved through better incorporation of gendered effects and interactions, such as between paid and unpaid sectors of economies. Other feminist scholars have engaged in new forms of data collection and measurement such as the Gender Empowerment Measure (GEM), and more gender-aware theories such as the capabilities approach. Feminist economics is oriented towards the goal of "enhancing the well-being of children, women, and men in local, national, and transnational communities."
Commuting is periodically recurring travel between a place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental and health reasons. In middle-income countries, motorcycle commuting is very common.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, tertiary care, and public health.
Travel behavior is the study of what people do over geography, and how people use transport.
Employment is a relationship between two parties regulating the provision of paid labour services. Usually based on a contract, one party, the employer, which might be a corporation, a not-for-profit organization, a co-operative, or any other entity, pays the other, the employee, in return for carrying out assigned work. Employees work in return for wages, which can be paid on the basis of an hourly rate, by piecework or an annual salary, depending on the type of work an employee does, the prevailing conditions of the sector and the bargaining power between the parties. Employees in some sectors may receive gratuities, bonus payments or stock options. In some types of employment, employees may receive benefits in addition to payment. Benefits may include health insurance, housing, and disability insurance. Employment is typically governed by employment laws, organisation or legal contracts.
Carpooling is the sharing of car journeys so that more than one person travels in a car, and prevents the need for others to have to drive to a location themselves. Carpooling is considered a Demand-Responsive Transport (DRT) service.
Children's culture includes children's cultural artifacts, children's media and literature, and the myths and discourses spun around the notion of childhood. Children's culture has been studied within academia in cultural studies, media studies, and literature departments. The interdisciplinary focus of childhood studies could also be considered in the paradigm of social theory concerning the study of children's culture.
Attention management refers to models and tools for supporting the management of attention at the individual or at the collective level, and at the short-term or at a longer term.
Media multitasking is the concurrent use of multiple digital media streams. Media multitasking has been associated with depressive symptoms and social anxiety by a study involving 318 participants. A 2018 review found that while the literature is sparse and inconclusive, people who do a heavy amount of media multitasking have worse performance in several cognitive domains. One of the authors commented that while the data does not "unambiguously show that media multitasking causes a change in attention and memory," media multitasking is an inefficient practice that requires "task switching" costs including "limitations in auditory and visual processing".
A schedule or a timetable, as a basic time-management tool, consists of a list of times at which possible tasks, events, or actions are intended to take place, or of a sequence of events in the chronological order in which such things are intended to take place. The process of creating a schedule — deciding how to order these tasks and how to commit resources between the variety of possible tasks — is called scheduling, and a person responsible for making a particular schedule may be called a scheduler. Making and following schedules is an ancient human activity.
Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car.
Deviance or the sociology of deviance explores the actions and/or behaviors that violate social norms across formally enacted rules as well as informal violations of social norms. Although deviance may have a negative connotation, the violation of social norms is not always a negative action; positive deviation exists in some situations. Although a norm is violated, a behavior can still be classified as positive or acceptable.
Unpaid labor or unpaid work is defined as labor or work that does not receive any direct remuneration. This is a form of non-market work which can fall into one of two categories: (1) unpaid work that is placed within the production boundary of the System of National Accounts (SNA), such as gross domestic product (GDP); and (2) unpaid work that falls outside of the production boundary, such as domestic labor that occurs inside households for their consumption. Unpaid labor is visible in many forms and is not limited to activities within a household. Other types of unpaid labor activities include volunteering as a form of charity work and interning as a form of unpaid employment. In a lot of countries, unpaid domestic work in the household is typically performed by women, due to gender inequality and gender norms, which can result in high-stress levels in women attempting to balance unpaid work and paid employment. In poorer countries, this work is sometimes performed by children.
Work intensity is defined as activity in relation to the capacity for that work. It is a topic that affects developed and developing countries in different ways. There are many aspects to work intensity including multitasking, time poverty, health implications, and policy considerations. Multitasking is the overlap of many activities, usually care and informal work, that negatively impacts the livelihood of people, especially women, in the developing world. Time poverty is defined as the lack of time for leisure and rest activities after time spent working. High work intensity coupled with multitasking and time poverty has a negative correlation with health outcomes. Work intensity is seldom considered when proposing new policy and legislation. As more women enter the workforce, work intensity and its implications are being brought to the forefront of policy, development, and empowerment debates.
Multi-communicating is the act of managing multiple conversations simultaneously. The term was coined by Reinsch, Turner, and Tinsley, who proposed that simultaneous conversations can be conducted using an array of media, including face-to-face, phone, and email tools for communication. The practice allows individuals to utilize two or more technologies to interact with each other.
Transport divide refers to unequal access to transportation. It can result in the social exclusion of disadvantaged groups.
Work or labor is the intentional activity people perform to support the needs and desires of themselves, other people, or organizations. In the context of economics, work can be viewed as the human activity that contributes towards the goods and services within an economy.
