Long COVIDLong COVID or long-haul COVID is a series of health problems persisting or developing after an initial COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. The World Health Organization defines long COVID to start three months after infection, but other definitions put the start of long COVID at four weeks. Long COVID is characterised by a large number of symptoms. Symptoms sometimes disappear and reappear. Commonly reported symptoms of long COVID are fatigue, memory problems, shortness of breath, and sleep disorder.
Workplace bullyingWorkplace bullying is a persistent pattern of mistreatment from others in the workplace that causes either physical or emotional harm. It can include such tactics as verbal, nonverbal, psychological, and physical abuse, as well as humiliation. This type of workplace aggression is particularly difficult because, unlike the typical school bully, workplace bullies often operate within the established rules and policies of their organization and their society.
Employee engagementEmployee engagement is a fundamental concept in the effort to understand and describe, both qualitatively and quantitatively, the nature of the relationship between an organization and its employees. An "engaged employee" is defined as one who is fully absorbed by and enthusiastic about their work and so takes positive action to further the organization's reputation and interests. An engaged employee has a positive attitude towards the organization and its values.
Public Health Agency of CanadaThe Public Health Agency of Canada (PHAC; Agence de la santé publique du Canada, ASPC) is an agency of the Government of Canada that is responsible for public health, emergency preparedness and response, and infectious and chronic disease control and prevention. The PHAC was formed because of a series of official inquiries about the SARS crisis in Canada which was particularly severe. For example, the province of Ontario inquiry and the National Advisory Committee on SARS and Public Health both recommended that a new organisation be formed.
Google AssistantGoogle Assistant is a virtual assistant software application developed by Google that is primarily available on mobile and home automation devices. Based on artificial intelligence, Google Assistant can engage in two-way conversations, unlike the company's previous virtual assistant, Google Now. Google Assistant debuted in May 2016 as part of Google's messaging app Allo, and its voice-activated speaker Google Nest.
Sequential analysisIn statistics, sequential analysis or sequential hypothesis testing is statistical analysis where the sample size is not fixed in advance. Instead data are evaluated as they are collected, and further sampling is stopped in accordance with a pre-defined stopping rule as soon as significant results are observed. Thus a conclusion may sometimes be reached at a much earlier stage than would be possible with more classical hypothesis testing or estimation, at consequently lower financial and/or human cost.
Employee retentionEmployee retention is the ability of an organization to retain its employees and ensure sustainability. Employee retention can be represented by a simple statistic (for example, a retention rate of 80% usually indicates that an organization kept 80% of its employees in a given period). Employee retention is also the strategies employers use to try to retain the employees in their workforce. A distinction should be drawn between low-performing employees and top performers, and efforts to retain employees should be targeted at valuable, contributing employees.
Facial recognition systemA facial recognition system is a technology potentially capable of matching a human face from a or a video frame against a database of faces. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image. Development began on similar systems in the 1960s, beginning as a form of computer application. Since their inception, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics.
Statistical inferenceStatistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population. Inferential statistics can be contrasted with descriptive statistics. Descriptive statistics is solely concerned with properties of the observed data, and it does not rest on the assumption that the data come from a larger population.
Publicly funded health carePublicly funded healthcare is a form of health care financing designed to meet the cost of all or most healthcare needs from a publicly managed fund. Usually this is under some form of democratic accountability, the right of access to which are set down in rules applying to the whole population contributing to the fund or receiving benefits from it. The fund may be a not-for-profit trust that pays out for healthcare according to common rules established by the members or by some other democratic form.
