For the clinical nurse specialist CNS engaged in research or evidence-based practice EBP , a concept analysis can provide guidance when a concept of interest does not have sufficient literature, is vaguely defined, or is not understood clearly or when literature and research do not match. There are several approaches to a concept analysis including, but not limited to, the approaches by Chinn and Jacobs, 2 Walker and Avant, 3 Rodgers, 4 and Sartori. A concept represents a symbol or a building block of a bigger spectrum; it is the basis of what the researcher wants to pursue.

An operational definition specifies concrete, replicable procedures that reliably produce a differentiated, measurable outcome. Properties described in this manner must be sufficiently accessible so that people other than the definer may independently measure or test for them at will. The most operational definition is a process for identification of an object by distinguishing it from its background of empirical experience. The binary version produces either the result that the object exists, or that it doesn't, in the experiential field to which it is applied.
The classifier version results in discrimination between what is part of the object and what is not part of it. This is also discussed in terms of semantics , pattern recognition , and operational techniques, such as regression. Operationalize means to put into operation or use. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation or validation  testing, which is repeatable at will.
For example, degrees Celsius may be crudely defined by describing the process of heating water at sea level until it is observed to boil. An item like a brick, or even a photograph of a brick, may be defined in terms of how it can be made. Likewise, iron may be defined in terms of the results of testing or measuring it in particular ways. Despite the controversial philosophical origins of the concept, particularly its close association with logical positivism , operational definitions have undisputed practical applications.
This is especially so in the social and medical sciences, where operational definitions of key terms are used to preserve the unambiguous empirical testability of hypothesis and theory.
Operational definitions are also important in the physical sciences. The Stanford Encyclopedia of Philosophy entry on scientific realism, written by Richard Boyd , indicates that the modern concept owes its origin in part to Percy Williams Bridgman , who felt that the expression of scientific concepts was often abstract and unclear. Inspired by Ernst Mach , in Bridgman attempted to redefine unobservable entities concretely in terms of the physical and mental operations used to measure them.
From the beginning objections were raised to this approach, in large part around the inflexibility. As Boyd notes, "In actual, and apparently reliable, scientific practice, changes in the instrumentation associated with theoretical terms are routine, and apparently crucial to the progress of science.
According to a 'pure' operationalist conception, these sorts of modifications would not be methodologically acceptable, since each definition must be considered to identify a unique 'object' or class of objects.
The special theory of relativity can be viewed as the introduction of operational definitions for simultaneity of events and of distance , that is, as providing the operations needed to define these terms. In quantum mechanics the notion of operational definitions is closely related to the idea of observables , that is, definitions based upon what can be measured.
Operational definitions are often most challenging in the fields of psychology and psychiatry , where intuitive concepts, such as intelligence need to be operationally defined before they become amenable to scientific investigation, for example, through processes such as IQ tests.
The subsequent enquiry found that the failure arose because engineers had specified the supply of a quantity of flat steel plate. The word flat in this context lacked an operational definition, so there was no test for accepting or rejecting a particular shipment or for controlling quality. In his managerial and statistical writings, W. Edwards Deming placed great importance on the value of using operational definitions in all agreements in business. As he said:. As a working method, it does not consider issues related to a domain that are more general, such as the ontological , etc.
Science uses computing. Computing uses science. We have seen the development of Computer Science. There are not many who can bridge all three of these.
One effect is that, when results are obtained using a computer, the results can be impossible to replicate if the code is poorly documented, contains errors, or if parts are omitted entirely. Many times, issues are related to persistence and clarity of use of variables, functions, and so forth. Also, systems dependence is an issue.
In brief, length as a standard has matter as its definitional basis. What pray tell can be used when standards are to be computationally framed? Hence, operational definition can be used within the realm of the interactions of humans with advanced computational systems. In this sense, one area of discourse deals with computational thinking in, and with how it might influence, the sciences.
One referenced project pulled together fluid experts, including some who were expert in the numeric modeling related to computational fluid dynamics, in a team with computer scientists. Essentially, it turned out that the computer guys did not know enough to weigh in as much as they would have liked. Thus, their role, to their chagrin, many times was "mere" programmer. Some knowledge-based engineering projects experienced similarly that there is a trade-off between trying to teach programming to a domain expert versus getting a programmer to understand the intricacies of a domain.
That, of course, depends upon the domain. In short, any team member has to decide which side of the coin to spend one's time. The International Society for Technology in Education has a brochure detailing an "operational definition" of computational thinking. At the same time, the ISTE made an attempt at defining related skills. A recognized skill is tolerance for ambiguity and being able to handle open-ended problems. For instance, a knowledge-based engineering system can enhance its operational aspect and thereby its stability through more involvement by the subject-matter expert , thereby opening up issues of limits that are related to being human.
As in, many times, computational results have to be taken at face value due to several factors hence the duck test 's necessity arises that even an expert cannot overcome.
The end proof may be the final results reasonable facsimile by simulation or artifact , working design, etc. In advanced modeling, with the requisite computational support such as knowledge-based engineering, mappings must be maintained between a real-world object, its abstracted counterparts as defined by the domain and its experts, and the computer models.
Mismatches between domain models and their computational mirrors can raise issues apropos this topic. Techniques that allow the flexible modeling required for many hard problems must resolve issues of identity, type, etc. Many domains, with a numerics focus, use limit theory, of various sorts, to overcome the duck test necessity with varying degrees of success.
Yet, with that, issues still remain as representational frameworks bear heavily on what we can know. In arguing for an object-based methodology, Peter Wegner  suggested that "positivist scientific philosophies, such as operationalism in physics and behaviorism in psychology" were powerfully applied in the early part of the 20th century.
However, computation has changed the landscape. He notes that we need to distinguish four levels of "irreversible physical and computational abstraction" Platonic abstraction, computational approximation, functional abstraction, and value computation. Then, we must rely on interactive methods, that have behavior as their focus see duck test. This is all highly abstract and unsuited for the day-to-day world of science and trade. In order to make the idea concrete, temperature is defined in terms of operations with the gas thermometer.
However, these are sophisticated and delicate instruments, only adapted to the national standardization laboratory. For day-to-day use, the International Temperature Scale of ITS is used, defining temperature in terms of characteristics of the several specific sensor types required to cover the full range.
One such is the electrical resistance of a thermistor , with specified construction, calibrated against operationally defined fixed points. Electric current is defined in terms of the force between two infinite parallel conductors, separated by a specified distance.
This definition is too abstract for practical measurement, so a device known as a current balance is used to define the ampere operationally. Unlike temperature and electric current , there is no abstract physical concept of the hardness of a material. It is a slightly vague, subjective idea, somewhat like the idea of intelligence. In fact, it leads to three more specific ideas:. Of these, indentation hardness itself leads to many operational definitions, the most important of which are:.
In all these, a process is defined for loading the indenter, measuring the resulting indentation, and calculating a hardness number. Each of these three sequences of measurement operations produces numbers that are consistent with our subjective idea of hardness.
The harder the material to our informal perception, the greater the number it will achieve on our respective hardness scales. Furthermore, experimental results obtained using these measurement methods has shown that the hardness number can be used to predict the stress required to permanently deform steel, a characteristic that fits in well with our idea of resistance to permanent deformation. However, there is not always a simple relationship between the various hardness scales. Vickers and Rockwell hardness numbers exhibit qualitatively different behaviour when used to describe some materials and phenomena.
The constellation Virgo is a specific constellation of stars in the sky, hence the process of forming Virgo cannot be an operational definition, since it is historical and not repeatable.
Nevertheless, the process whereby we locate Virgo in the sky is repeatable, so in this way, Virgo is operationally defined. In fact, Virgo can have any number of definitions although we can never prove that we are talking about the same Virgo , and any number may be operational. New academic disciplines appear in response to interdisciplinary activity at universities. An academic suggested that a subject matter area becomes a discipline when there are more than a dozen university departments using the same name for roughly the same subject matter.

Psychological Review 42 6 : — Only those constructs based upon operations which are public and repeatable are admitted to the body of science. A term or proposition has meaning denotes something if, and only if, the criteria of its applicability or truth consist of concrete operations which can be performed.

Toward an Understanding of Wisdom in Nursing
Susan A. This article addresses wisdom-in-action for nursing practice. We briefly describe nursing theory , review the wisdom literature as presented in various disciplines, and identify characteristics of wisdom by analyzing four models of wisdom from other disciplines. We also present the ten antecedents of wisdom and the ten characteristics of wisdom identified in our analysis of the wisdom literature, discuss and summarize these antecedents, and conclude that understanding these ten antecedents and the ten characteristics of wisdom-in-action can both help nurses demonstrate wisdom as they provide nursing care and teach new nurses the process of becoming wise in nursing practice. Citation: Matney, S. Keywords: wisdom, knowledge, informatics, concept analysis, antecedents of wisdom, characteristics of wisdom, wisdom-in-action. Where is the wisdom we have lost in knowledge?

Concept analysis is a strategy used for examining concepts for their semantic structure. Although there are several methods for conducting concept analysis, all of the methods have the purpose of determining the defining attributes or characteristics of the concept under study. Some uses of a concept analysis are refining and clarifying concepts in theory, practice, and research and arriving at precise theoretical and operational definitions for research or for instrument development.
Health Services Research, Part 4: Conceptual and Operational Definitions
Since nursing has come of age both as a profession and as a scholarly discipline, there has been increasing concern with delineating its theory base. In Chinn and Jacobs asserted that "the development of theory is the most crucial task facing nursing today. Concept formation begins in infancy, for concepts help us to categorize and organize our environmental stimuli.
Do conceptual and operational definitions matter? A major flaw of most surveys utilized in health services research is failure to develop an appropriate level of specificity in defining what is to be measured. This causes healthcare organizations to use instruments that can be vague or confusing for both survey administrators — and for respondents. The resulting data is often difficult to analyze and a significant amount of time and resources may have been wasted if the final survey results are of minimal use to the organization. After the survey design team has crafted a clear statement of research purpose, they must create data collection questions that will allow them to gather information that accurately reflects the assessment domains or variables indicated in the research questions. However, this is deceptively difficult because few assessment domains are easily measurable. In addition, any given area to be assessed may have several dimensions discussed in Part 2 of this series.

Grounded theory - conceptual and operational aspects: a method possible to be applied in nursing research. This is a descriptive-reflective study based on literature and qualitative design. It aimed to discuss conceptual aspects of Grounded Theory GT and to present the applicability of this methodology within the nursing field. GT consists of an interpretative and systematic framework that extracts significant aspects from experiences of social actors and which enables researchers to construct theoretical frameworks and intensify expansion of knowledge. It has been shown to be an important and consistent framework for objects of study that involve human interactions and which include phenomena concerning professional practice and which have not yet been properly examined and understood according to the rigor required for the construction of knowledge in qualitative designs. Descriptors: nursing; research nursing; nursing methodology research. Grounded Theory GT aims to understand reality from the conception or meaning people hold about a certain context or object, so as to generate knowledge, improve understanding and provide a meaningful guide for action 1.
Шеф внезапно замолчал и растворился во тьме. Это пугало Хейла. Он понимал, что времени у него. Агенты могут появиться в любую минуту. Собрав все силы, Хейл, сильнее обхватив Сьюзан за талию, начал пятясь подниматься по лестнице.
Он все рассказал, нажал клавишу PRINT и застрелился. Хейл поклялся, что никогда больше не переступит порога тюрьмы, и сдержал слово, предпочтя смерть. - Дэвид… - всхлипывала. - Дэвид. В этот момент в нескольких метрах под помещением шифровалки Стратмор сошел с лестницы на площадку. Сегодняшний день стал для него днем сплошных фиаско. То, что началось как в высшей степени патриотическая миссия, самым неожиданным образом вышло из-под контроля.
Дэвид на экране застыл в глубокой задумчивости. - Разница, - бормотал он себе под нос. - Разница между U235 и U238. Должно быть что-то самое простое. Техник в оперативном штабе начал отсчет: - Пять.
Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах. Она снова прошлась по кнопкам. Они не реагировали. - Выключите ТРАНСТЕКСТ! - потребовала. Остановка поисков ключа Цифровой крепости высвободила бы достаточно энергии для срабатывания дверных замков.
Si, senor, - засмеявшись, ответила Мидж с подчеркнутым пуэрто-риканским акцентом и, подмигнув Бринкерхоффу, направилась к двойной двери директорского кабинета. Личный кабинет Лиланда Фонтейна ничем не походил на остальные помещения дирекции. В нем не было ни картин, ни мягкой мебели, ни фикусов в горшках, ни антикварных часов. Здесь все было подчинено одному требованию - эффективности.
