and Fulk, J. Note that it is possible to predict events or behaviors using a set of predictors, without necessarily explaining why such events are taking place. When you do research you are basically trying to answer one of several questions, What, Why and how are the most fundamental ones. (1990). Idiographic explanations are those that explain a single situation or event in idiosyncratic detail. Furthermore, variables may be independent, dependent, mediating, or moderating, as discussed in Chapter 2. However, they explain economically, using only a few explanatory variables. Agency theory also recommends tools that principals may employ to improve the efficacy of behavior-based contracts, such as investing in monitoring mechanisms (such as hiring supervisors) to counter the information asymmetry caused by moral hazard, designing renewable contracts contingent on agent’s performance (performance assessment makes the contract partially outcome-based), or by improving the structure of the assigned task to make it more programmable and therefore more observable. In contrast, nomothetic explanations seek to explain a class of situations or events rather than a specific situation or event. Subjective norm refers to one’s perception of whether people important to that person expect the person to perform the intended behavior, and represented as a weighted combination of the expected norms of different referent groups such as friends, colleagues, or supervisors at work. Nevertheless, all constructs must have clear and unambiguous operational definition that should specify exactly how the construct will be measured and at what level of analysis (individual, group, organizational, etc.). Hence, the goal incongruence. Hence, a criminal’s personal situation (such as his personal values, his affluence, and his need for money) and the environmental context (such as how protected is the target, how efficient is the local police, how likely are criminals to be apprehended) play key roles in this decision making process. New York: The Free Press. Theory can be defined as “a formal logical explanation of some events that includes predictions of how things relate to one another”[1]. Alternatively, concepts are “mental constructs or images developed to symbolise ideas, persons, … Measurable representations of abstract constructs are called variables . It explains how individuals can be influenced to change their attitude toward a certain object, events, or behavior and the relative efficacy of such change strategies. Other examples of quantitative variables include pe… Just as a nuclear explosion requires a critical mass of radioactive material to sustain a nuclear explosion, Markus suggested that a network requires a critical mass of users to sustain its growth, and without such critical mass, users may leave the network, causing an eventual demise of the network. This ability and motivation to elaborate is called elaboration likelihood . All researchers should consider the theoretical basis for their studies very early on in the planning stage. It can be defined as “a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained” (Oxford dictionary). For instance, intelligence quotient (IQ score) is a variable that is purported to measure an abstract construct called intelligence. Theory 1. Much of the skepticism about theory is based on the assumption that education in general, and educational administration in particular, is art, not science, a skepticism that has plagued all social sciences. https://www.differencebetween.com/difference-between-concept-and-vs-theory The two parties in this theory are the principal and the agent; the principal employs the agent to perform certain tasks on its behalf. Theory as orientation. The third building block of a theory is the logic that provides the basis for justifying the propositions as postulated. “Organizational Theories: Some Criteria for Evaluation,” Academy of Management Review (14:4), 496-515. This deductive approach leverages the rich inventory of social science theories developed by prior theoreticians, and is an efficient way of building new theories by building on existing ones. The aim of this paper is to describe and discuss how theory (a ‘comprehensive explanation of some aspect of nature that is supported by a body of evidence’) can inform and improve the quality and relevance of pharmacy-based research. The concepts of a research study relate back to the theory. (1989). Likewise, theories may have implicit cultural assumptions (e.g., whether they apply to individualistic or collective cultures), temporal assumptions (e.g., whether they apply to early stages or later stages of human behavior), and spatial assumptions (e.g., whether they apply to certain localities but not to others). For example, many economic theories assume that human beings are rational (or boundedly rational) and employ utility maximization based on cost and benefit expectations as a way of understand human behavior. Third, theories provide guidance for future research by helping identify constructs and relationships that are worthy of further research. Developed by Petty and Cacioppo (1986) [7], the elaboration likelihood model (ELM) is a dual-process theory of attitude formation or change in the psychology literature. 2) Descriptive - gathers descriptive data to describe what is really happening. Attitude is defined as the individual’s overall positive or negative feelings about performing the behavior in question, which may be assessed as a summation of one’s beliefs regarding the different consequences of that behavior, weighted by the desirability of those consequences. The concept was first studied by French sociologist Gabriel Tarde, but the theory was developed by Everett Rogers in 1962 based on observations of 508 diffusion studies. The concept of the theory is significant in any discipline that considers itself scientific or scholarly. It presumes that individual behavior represents conscious reasoned choice, and is shaped by cognitive thinking and social pressures. The process of contemplative and rational thinking often is associated with such processes like observational study, research. INTRODUCTION AND CONCEPT OF RESEARCH Presenter Name Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The chosen major of the students is also a variable as long as not everyone in the class has declared the same major. We will discuss the grounded theory approach in a later chapter on qualitative research. How can we evaluate the “goodness” of a given theory? This theory has interesting implications not only for traditional crimes, but also for contemporary white-collar crimes such as insider trading, software piracy, and illegal sharing of music. On the other hand, … Role of Theory in Research. Swiftness, severity, and certainty of punishments are the key constructs in GDT. This approach relies on reasoning by analogy, and is probably the most creative way of theorizing using a deductive approach. This unit shows how facts can be subordinated to general principles or laws and how they relate to them. Agency Theory. For example, the height of the students enrolled in a university course is a variable because it varies from student to student. This is somewhat an inductive method or approach. [1] Zikmund, W.G., Babin, J., Carr, J. Alternatively, concepts are “mental constructs or images developed to symbolise ideas, persons, things, or events”[3], Model can be defined as “a set of ideas and numbers that describe the past, present or future state of something”[4], A framework is “a system of rules, laws, agreements, etc. Note that propositions may be conjectural but MUST be testable, and should be rejected if they are not supported by empirical observations. A scientific theory must be consistent with the facts, otherwise it is mere fiction. Recall from Chapter 2 that constructs may be unidimensional (i.e., embody a single concept), such as weight or age, or multi-dimensional (i.e., embody multiple underlying concepts), such as personality or culture. A developmental psychologist begins a research study after developing ideas from a theory, or an integrated set of statements, that explain various phenomena. Theory is a natural extension of the philosophy of science, and a theoretical framework(s) will typically underpin most research studies. There are many benefits to using theories in research. Unfortunately, theorists rarely state their implicit assumptions clearly, which leads to frequent misapplications of theories to problem situations in research. Theories can be verified by experiments or by methodological observation. The last two characteristics have since been dropped from many innovation studies. “The Theory of Planned Behavior,” Organizational Behavior and Human Decision Processes (50), 179-211. The procedure for good theory-building research follows the definition of theory: it defines the variables, specifies the domain, builds internally consistent relationships, and makes specific predictions. It is a science of studying how research is to be carried out. [1] Bacharach, S. B. For instance, a doctor may employ the central route for diagnosing and treating a medical ailment (by virtue of his or her expertise of the subject), but may rely on peripheral cues from auto mechanics to understand the problems with his car. In the sphere of education, a theory can be defined as a pool of principle and concepts purposed to explain a given phenomenon (Cooper et al., 2004). A major function of a theoretical system is that it narrows the range of facts to be studied. The four key elements in this theory are: innovation, communication channels, time, and social system… The difference between these two objectives is grounded in the purpose of the research. “Toward a ‘Critical Mass’ Theory of Interactive Media: Universal Access, Interdependence, and Diffusion,” Communication Research (14:5), 491-511. The following are the most popular ones listed in alphabetical order: Some of the above (hyperlinked) are explained in this portal. theory: A set of logically consistent ideas about the relationships between empirical phenomena (i.e., concepts) that permits those ideas to be tested using observations. Theory: A Scientific Concept Theory is one of those words that makes people uncomfortable, largely because of their misconceptions of the term. Some experts say that grounded research separates theory and data, while others say it combines the two. For example, you did poorly on an exam because: (1) you forgot that you had an exam on that day, (2) you arrived late to the exam due to a traffic jam, (3) you panicked midway through the exam, (4) you had to work late the previous evening and could not study for the exam, or even (5) your dog ate your text book. Theory’s pivotal importance has been emphasized in the information systems (IS) dis-cipline since its inception. In contrast, political science theories assume that people are more political than rational, and try to position themselves in their professional or personal environment in a way that maximizes their power and control over others. A theory is an explanation of some aspect of reality. They begin as a conceptual framework and with much research, develop into a research-based framework The latter route is less cognitively demanding, and the routes of attitude change are typically operationalized in the ELM using the argument quality and peripheral cues constructs respectively. All adopters are not identical, and adopters can be classified into innovators, early adopters, early majority, late majority, and laggards based on their time of their adoption. It unpacks the meaning of the two terms, and how they are related, making the case for theory as ‘tool’ in research that needs to be firmly connected to methodology, and data analysis. An employee stock option plans are is an example of an outcome-based contract while employee pay is a behavior-based contract. In a theory, concepts are knitted together into a coherent system to describe or explain some aspect of the world. [7] Petty, R. E., and Cacioppo, J. T. (1986). [3] Markus, M. L. (1987). In contrast, explanations require causations , or understanding of cause-effect relationships. A is a quantity or quality that varies across people or situations. 2. In this section, we present brief overviews of a few illustrative theories from different social science disciplines. As noted earlier, scientific research proceeds along two planes: a theoretical plane and an empirical plane. A collection of facts is not a theory, just as a pile of stones is not a house. Compounding the nature of the problem may be information asymmetry problems caused by the principal’s inability to adequately observe the agent’s behavior or accurately evaluate the agent’s skill sets. Development of theories 1) Speculative - attempts to explain what is happening. Because people naturally choose utility-maximizing behaviors, deviant choices that engender personal gain or pleasure can be controlled by increasing the costs of such behaviors in the form of punishments (countermeasures) as well as increasing the probability of apprehension. To that end, “target hardening” such as installing deadbolts and building self-defense skills, legal deterrents such as eliminating parole for certain crimes, “three strikes law” (mandatory incarceration for three offenses, even if the offenses are minor and not worth imprisonment), and the death penalty, increasing the chances of apprehension using means such as neighborhood watch programs, special task forces on drugs or gang -related crimes, and increased police patrols, and educational programs such as highly visible notices such as “Trespassers will be prosecuted” are effective in preventing crimes. Because a theory is too general to test, the investigator devises a hypothesis —a testable prediction—from the theory and tests the hypothesis instead of a general theory. The theoretical framework is the structure that can hold or support a theory of a research study. Conceptual research doesn’t involve conducting any practical experiments. These theories explain different types of social behaviors, using a set of constructs, propositions, boundary conditions, assumptions, and underlying logic. Elaboration Likelihood Model . Likewise, a collection of constructs (e.g., a typology of constructs) is not a theory, because theories must go well beyond constructs to include propositions, explanations, and boundary conditions. Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. [6] Rogers, E. (1962). `Good' theory-building research's purpose is to build an integrated body of knowledge to be applied to many instances by explaining who, what, when, where, how and why certain phenomena will occur. “According to the theory, enhanced comfort strengthens recipients….to engage in activities necessary to achieving health and remaining healthy” ( Kolcaba & DiMarco, 2005, p.189 ). Finally, all theories are constrained by assumptions about values, time, and space, and boundary conditions that govern where the theory can be applied and where it cannot be applied. A theory is a contemplative and rational type of abstract or generalizing thinking about a phenomenon, or the results of such thinking. This is also an inductive approach that relies heavily on the inductive abilities of the researcher, and interpretation may be biased by researcher’s prior knowledge of the phenomenon being studied. The distinction between constructs (conceptualized at the theoretical level) and variables (measured at the empirical level) is shown in Figure 4.1. The focus of GDT is not how to rehabilitate criminals and avert future criminal behaviors, but how to make criminal activities less attractive and therefore prevent crimes.
