Survival Tour
Survival, or the act of surviving, is the propensity of something to continue existing, particularly when this is done despite conditions that might kill or destroy it. The concept can be applied to humans and other living things (or, hypothetically, any sentient being), to physical object, and to abstract things such as beliefs or ideas. Living things generally have a self-preservation instinct to survive, while objects intended for use in harsh conditions are designed for survivability. Meaning The word, "survival", derives from the Late Latin '' supervivere'', literally meaning "to outlive". Most commonly, "the term 'survival' means physical survival — that is, a struggle to avoid physical extermination". For example, Charles Darwin's theory of natural selection incorporates the concept of the survival of the fittest in the struggle for existence. Darwin defines the biological concept of fitness as reproductive success, so in Darwinian terms the phrase is best understood ...

Surviving Spouse
A widow (female) or widower (male) is a person whose spouse has died. Terminology The state of having lost one's spouse to death is termed ''widowhood''. An archaic term for a widow is "relict," literally "someone left over". This word can sometimes be found on older gravestones. The word "widow" comes from an Indo-European root meaning "widow" and has cognates across Indo-European languages. The male form, "widower", is first attested in the 14th century, by the 19th century supplanting "widow" with reference to men. The term ''widowhood'' can be used for either sex, at least according to some dictionaries, but the word ''widowerhood'' is also listed in some dictionaries. Occasionally, the word ''viduity'' is used. The adjective for either sex is ''widowed''. These terms are not applied to a divorcé(e) following the death of an ex-spouse. Effects on health The phenomenon that refers to the increased mortality rate after the death of a spouse is called the ''widowhood e ...

Natural Disaster
A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Examples of natural hazards include: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane (tropical cyclone), ice storm, landslide, lightning, riverine flooding, strong wind, tornado, typhoon, tsunami, volcanic activity, wildfire, winter weather. In modern times, the divide between natural, man-made and man-accelerated disasters is quite difficult to draw. Human choices and activities like architecture, fire, resource management or even climate change potentially play a role in causing "natural disasters". In fact, the term "natural disaster" has been called a misnom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Getting Lost
Getting lost is the occurrence of a person or animal losing spatial reference. This situation consists of two elements: the feeling of disorientation and a spatial component. While ''getting lost'', ''being lost'' or ''totally lost'', etc. are popular expressions for someone in a desperate situation (perhaps not literally lost), getting lost is also a positive term for a goal some travellers have in exploring without a plan. Getting lost can also occur in metaphorical senses, such as being unable to follow a conversation. Process Psychology and neuroscience help to understand the underlying processes which take place before, during and after getting lost. Getting lost is an aspect of behavioral geography, in which human wayfinding and cognitive and environmental factors play a role. For successful travel, it is necessary to be able to identify origin and destination, to determine turn angles, to identify segment lengths and directions of movement, to recognize on-route and distant ...

Survival Skills
Survival skills are techniques that a person may use in order to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life which include water, food, and shelter. These skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over a period of time. Survival skills are often associated with the need to survive in a disaster situation. Survival skills are often basic ideas and abilities that ancient people invented and used themselves for thousands of years. Outdoor activities such as hiking, backpacking, horseback riding, fishing, and hunting all require basic wilderness survival skills, especially in handling emergency situations. Bushcraft and primitive living are most often self-implemented but require many of the same skills. First aid First aid (wilderness first aid in particular) can help a person survive and function with injuries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Survivalism
Survivalism is a social movement of individuals or groups (called survivalists or preppers) who proactively prepare for emergencies, such as natural disasters, as well as other disasters causing disruption to social order (that is, civil disorder) caused by political or economic crises. Preparations may anticipate short-term scenarios or long-term, on scales ranging from personal adversity, to local disruption of services, to international or global catastrophe. There is no bright line dividing general emergency preparedness from prepping in the form of survivalism (these concepts are a spectrum), but a qualitative distinction is often recognized whereby preppers/survivalists prepare especially extensively because they have higher estimations of the risk (odds) of catastrophes happening. Nonetheless, prepping can be as limited as preparing for a personal emergency (such as a job loss, storm damage to one's home, or getting lost in wooded terrain), or it can be as extensive ...

Prognosis
Prognosis (Greek: πρόγνωσις "fore-knowing, foreseeing") is a medical term for predicting the likely or expected development of a disease, including whether the signs and symptoms will improve or worsen (and how quickly) or remain stable over time; expectations of quality of life, such as the ability to carry out daily activities; the potential for complications and associated health issues; and the likelihood of survival (including life expectancy). A prognosis is made on the basis of the normal course of the diagnosed disease, the individual's physical and mental condition, the available treatments, and additional factors. A complete prognosis includes the expected duration, function, and description of the course of the disease, such as progressive decline, intermittent crisis, or sudden, unpredictable crisis. When applied to large statistical populations, prognostic estimates can be very accurate: for example the statement "45% of patients with severe septic shock w ...

Survival Rate
Survival rate is a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy. The survival period is usually reckoned from date of diagnosis or start of treatment. Survival rates are based on the population as a whole and cannot be applied directly to an individual. There are various types of survival rates (discussed below). They often serve as endpoints of clinical trials and should not be confused with mortality rates, a population metric. Overall survival Patients with a certain disease (for example, colorectal cancer) can die directly from that disease or from an unrelated cause (for example, a car accident). When the precise cause of death is not specified, this is called the overall survival rate or observed survival rate. Doctors often use mean overall survival ...

Statistics
Statistics (from German language, German: ''wikt:Statistik#German, Statistik'', "description of a State (polity), state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of statistical survey, surveys and experimental design, experiments.Dodge, Y. (2006) ''The Oxford Dictionary of Statistical Terms'', Oxford University Press. When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey sample (statistics), samples. Representative sampling as ...

Survival Analysis
Survival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology. Survival analysis attempts to answer certain questions, such as what is the proportion of a population which will survive past a certain time? Of those that survive, at what rate will they die or fail? Can multiple causes of death or failure be taken into account? How do particular circumstances or characteristics increase or decrease the probability of survival? To answer such questions, it is necessary to define "lifetime". In the case of biological survival, death is unambiguous, but for mechanical reliability, failure may not be well-defined, for there may well be mechanical systems in which failure is partial, a matter of ...

Life After Death
The afterlife (also referred to as life after death) is a purported existence in which the essential part of an individual's identity or their stream of consciousness continues to live after the death of their physical body. The surviving essential aspect varies between belief systems; it may be some partial element, or the entire soul or spirit of an individual, which carries with it and may confer personal identity or, on the contrary, nirvana. Belief in an afterlife is in contrast to the belief in eternal oblivion, oblivion after death. In some views, this continued existence takes place in a Supernatural, spiritual realm, while in others, the individual may be Reincarnation, reborn into World (theology), this world and begin the life cycle over again, likely with no memory of what they have done in the past. In this latter view, such rebirths and deaths may take place over and over again continuously until the individual gains entry to a spiritual realm or otherworld. Maj ...

Spirit (animating Force)
In folk belief, spirit is the vital principle or animating essence within all living things. As recently as 1628 and 1633 respectively, both William Harvey and René Descartes still speculated that somewhere within the body, in a special locality, there was a "vital spirit" or "vital force", which animated the whole bodily frame, just as the engine in a factory moves the machinery in it. Overview People have frequently conceived of spirit as a supernatural being, or non-physical entity; for example, a demon, ghost, fairy, or angel. In ancient Islamic terminology however, the term ''spirit'' (''rūḥ''), applies only to "pure" spirits, but not to other invisible creatures, such as jinn, demons and angels. Historically, spirit has been used to refer to a "subtle" as opposed to "gross" material substance, as put forth in the notable last paragraph of Sir Isaac Newton's ''Principia Mathematica''. In English Bibles, "the Spirit" (with a capital "S"), specifically denotes the Hol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
