This paper deals with causal analysis in the social sciences. We first present a conceptual framework according to which causal analysis is based on a rationale of variation and invariance, and not only on regularity. We then develop a formal framework for causal analysis by means of structural modelling. Within this framework we approach causality in terms of exogeneity in a structural conditional model based which is based on (i) congruence with background knowledge, (ii) invariance under a large variety of (...) environmental changes, and (iii) model fit. We also tackle the issue of confounding and show how latent confounders can play havoc with exogeneity. This framework avoids making untestable metaphysical claims about causal relations and yet remains useful for cognitive and action-oriented goals. (shrink)

This article analyzes the impact of the rights-oriented business ethics course on student's ethical orientation. This approach, which is predominant in business schools, excludes the care-oriented approach used by a majority of women as well as some men and minorities. The results of this study showed that although students did not shift significantly in their ethical orientation, a majority of the men and an even greater majority of the women were care-oriented before and after a course in business ethics. If (...) business schools are to address society's increasing diversity then the perspective of women and others who are care-oriented must be assimilated into the curriculum. This can only be done by rethinking how the business ethics course (and the entire business curriculum) are taught to include a care-oriented approach. (shrink)

Background We report a randomised controlled clinical trial of neurofeedback therapy intervention for ADHD/ADD in adults. We focus on internal mechanics of neurofeedback learning, to elucidate the primary role of cortical self-regulation in neurofeedback. We report initial results; more extensive analysis will follow. Methods Trial has two phases: intervention and follow-up. The intervention consisted of neurofeedback treatment, including intake and outtake measurements, using a waiting-list control group. Treatment involved $\sim$40 hour-long sessions 2-5 times per week. Training involved either theta/beta or (...) sensorimotor-rhythm regimes, adapted by adding a novel 'inverse-training' condition to promote self-regulation. Follow-up (ongoing) will consist of self-report and executive function tests. Setting Intake and outtake measurements were conducted at University of Helsinki. Treatment was administered at partner clinic Mental Capital Care, Helsinki. Randomisation We randomly allocated half the sample then adaptively allocated the remainder to minimise baseline differences in prognostic variables. Blinding Waiting-list control design meant trial was not blinded. Participants 54 adult Finnish participants (mean age 36 years; 29 females) were recruited after screening by psychiatric review. 44 had ADHD diagnoses, 10 had ADD. Measurements Symptoms were assessed by computerised attention test (T.O.V.A.) and self-report scales, at intake and outtake. Performance during neurofeedback trials was recorded. Results Participants were recruited and completed intake measurements during summer 2012, before assignment to treatment and control, September 2012. Outtake measurements ran April-August 2013. After dropouts, 23 treatment and 21 waiting-list participants remained for analysis. Initial analysis showed that, compared to waiting-list control, neurofeedback promoted improvement of self-reported ADHD symptoms, but did not show transfer of learning to T.O.V.A. Comprehensive analysis will be reported elsewhere. Trial Registration "Computer Enabled Neuroplasticity Treatment (CENT)", ISRCTN13915109.

There is an increasing demand by society that university students demonstrate competitive skills to enable them to achieve greater success when entering the workplace. Creativity and life satisfaction correlate positively with academic performance, productivity, and excellence in the working environment. The presence of creativity and emotional intelligence in the curriculum and teaching methods in Spanish universities, however, is surprisingly lacking. Studies that examine gender differences in these variables provide conflicting results. The purpose of our research is to analyse the changes (...) produced in both creativity and life satisfaction in university students by a positive emotional and creative intervention and explore individual differences by gender. The methodology used was a quasi-experimental pre- test/post- test design with experimental/control groups. Three hundred university students from the Community of Madrid completed three exercises that evaluated creativity and life satisfaction. The results show significantly higher results in creativity and life satisfaction in women, who continued to achieve high results after the intervention. Finally, we discuss the need for emotional and creative education in universities and focus on the employability and the guarantee of equal opportunities through the development of these competencies.

This study employs a pretest-posttest experimental design to extend recent research pertaining to the effects of teaching business ethics material. Results on a variety of perceptual and attitudinal measures are compared across three groups of students — one which discussed the ethicality of brief business situations (the business scenario discussion approach), one which was given a more philosophically oriented lecture (the philosophical lecture approach), and a third group which received no specific lecture or discussion pertaining to business ethics. Results showed (...) some significant differences across the three groups and demonstrated that for a single lecture, the method used to teach ethics can differentially impact ethical attitudes and perceptions. Various demographic and background variables did not moderate the relationship between the teaching method and the dependent variables, but the sex of the student was strongly associated with the ethical attitude and perception measures.

In three studies, factors influencing the incidence of fraudulent financial reporting were assessed. We examined (1) the effects of personal values and (2) codes of corporate conduct, on whether managers misrepresented financial reports. In these studies, executives and controllers were asked to respond to hypothetical situations involving fraudulent financial reporting procedures. The occurrence of fraudulent reporting was found to be high; however, neither personal values, codes of conduct, nor the interaction of the two factors played a significant role in fraudulent (...) financial reporting.

The need to align multiple experimental procedures and produce converging results so as to demonstrate that the phenomenon under investigation is real and not an artifact is a commonplace both in scientific practice and discussions of scientific methodology (Campbell and Stanley 1963; Wimsatt 1981). Although sometimes this is the purpose of aligning techniques, often there is a different purpose—multiple techniques are sought to supply different perspectives on the phenomena under investigation that need to be integrated to answer the questions scientists (...) are asking. After introducing this function, I will illustrate it by considering three of the major techniques in cognitive neuroscience for linking cognitive function with neural structure. (shrink)

Solidarity corresponds to virtuous social behavior, including personal freedom and responsibility, civic friendship, benevolence, reciprocity, and cooperation. These attributes are fundamentally good for individual persons and communities of work. Solidarity is therefore vitally important to the practice of humanistic management. This paper aims to provide management insights into the cultivation of solidarity. The paper begins by developing a theoretical framework to understand solidarity in business context, with attention to philosophical and theological connotations. An empirical research model is presented in the (...) form of a survey instrument to test for indications of solidarity in the workplace, and this measure is used to test several hypotheses regarding the positive associations of solidarity with validated measures of workplace engagement. Research results show that it is possible to identify and analyze workplace behaviors associated with solidarity. Data analysis confirms the validity of the model and demonstrates the positive associations of the hypotheses, based on empirical study of 40 workplaces and 399 employees. Moreover, the condition of whether the workplace was a public or private organization was found to affect the main relationship between solidarity and workplace engagement. The paper concludes with suggestions for practicable, tangible workplace behaviors based on the model, offering guidance in the pursuit of humanistic management. (shrink)

The author asks whether there was a “scientific ‘68”, and focuses on aspects of two specific methodological proposals defined in the 1940s and 50s by the terms “action research” and “mixing methods”, applied particularly to social sciences. In the first, the climate surrounding the events of 1968 contributed to heightening the participative element to be found –by definition– in “action research”; that is: the importance of making the research subjects themselves participants in the design, execution and application of the study (...) of which they are the focus. This approach captured the democratic and anti-authoritarian spirit at the heart of the proposal, which was part of the prevailing climate in those days. The repercussions of 1968 on “mixing methods” focused on studying what had actually occurred, especially between the youth and workers, and therefore, particularly from the point of view of sociology and social psychology, using a “mixed methods” approach. The author explores the proposal of Norman Denzin; but traces the recent origins of both “mixing methods” and “action research” back to the proposals of mainly Kurt Lewin and the Chicago School.

In this paper I ask how educational researchers can believe the subjective perceptions of qualitative participant-observers given the concern for objectivity and generalisability of experimental research in the behavioural and social sciences. I critique the most common answer to this question within the educational research community, which posits the existence of two (or more) equally legitimate epistemological paradigms—positivism and constructivism—and offer an alternative that places a priority in educational research on understanding the purposes and meanings humans attribute to educational practices. (...) Only within the context of what I call a transcendent view from somewhere—higher ideals that govern human activities—can we make sense of quantitative as well as qualitative research findings.

How good gets better and bad gets worse: measuring the face of emotion Given the history of the past, black South African students from different settings face unique academic and emotional climate. Using the Differential Emotions Scale which focuses on ten discrete emotions, and building upon Boyle's seminal work, this study reports a repeated-measure multiple discriminant function analysis for individual items across raters. The findings further indicate that majority of the DES items are sensitive indicators of the different innate and (...) universal facial expressions. However, the construct requires revision so that it offers the examiner maximum flexibility in assessment at diverse levels, in terms of more extensive norming and programmatic replication. In brief, the DES potentially has much to offer provided that it is adequately developed for use in non-Western nations or contexts. (shrink)

This Differential Emotions Scale (DES) is an objective pencil-and-paper instrument designed to measure the subjective-experience components of the fundamental emotions, based on the assumption that mood states involved a characteristic pattern. Following Boyle (Boyle, G.J. Reliability and validity of Izard's Differential Emotions Scale, Personality, 56, pp. 747-750, 1984), the present paper reports a repeated-measure multiple discriminant function analysis for individual items across raters. At least, two-thirds of the DES items are sensitive indicators of the different mood states, however, the construct (...) validity of the subscales is not clear. In particular, the profiles for the South African participants indicated that there is need for improving the construct validity and retest reliability of DES in order to be useful in applied psychological contexts in non-Western nations.

The aim of this study was to find out whether the achievement of high school social studies students differs significantly according to whether they are taught by the reflective teaching method or the lecture approach method. A stratified random sample of 215 year three social studies students was randomly assigned to two groups: 107 students into the reflective approach group and 108 into the lecture approach group. An achievement test was used as the pre‐ and the post‐test. The means of (...) the aggregate mean performance scores were compared by the use of Student's t‐test. There was no significant difference between the two groups on the pre‐test scores but there was a significant difference between the post‐test scores, in favour of the group taught by the reflective approach method.

How has sociology framed places of knowledge production and what is the specific power of the laboratory for this history? This article looks in three steps at how sociology and Science and Technology Studies (STS) have historically framed the world as laboratory. First, in early sociology, the laboratory was an important metaphor to conceive of sociology as a scientific enterprise. In the 1950s, the trend reversed and with the emergence of a ‘qualitative sociology’, sociology was seen in opposition to laboratory (...) work. With the ascent of laboratory studies, the laboratory perspective was again applied to many fields, including sociology itself. Based on a definition of a laboratory as aiming at placeless knowledge and being inconsequential this article argues that the two waves of laboratorization were metaphorical and did not really turn the world into a laboratory. Instead, two alternative concepts, those of the unilatory and the locatory, are proposed to gain a more precise understanding of some of these metaphorical uses of the term ‘laboratory’. (shrink)

There are many important methodological decisions that need to be made when examining emotional reactivity in psychopathology. In the present study, we examined the effects of two such decisions in an investigation of emotional reactivity in depression: (1) which (if any) comparison condition to employ; and (2) how to define change. Depressed (N = 69) and control (N = 37) participants viewed emotion-inducing film clips while subjective and facial responses were measured. Emotional reactivity was defined using no comparison condition (i.e., (...) raw scores), baseline comparison condition (i.e., no stimulus presented), and neutral comparison condition (i.e., neutral stimulus presented). Change in emotional reactivity was assessed using four analytic approaches: difference scores, percentage change, residualised change, and ANCOVA. Results differed among the three comparison conditions and among several of the analytic approaches. Overall, our investigation suggests that choosing a comparison condition and the definition of change can significantly influence the presence of group differences in emotional reactivity. Recommendations for studies of emotional reactivity in psychopathology are discussed. (shrink)

While first-person methods are essential for a science of consciousness, it is controversial what form these methods should take and whether any such methods are reliable. I propose that first-person experiments are a reliable method for investigating conscious experience. I outline the history of these methods and describe their characteristics. In particular, a first-person experiment is an intervention on a subject's experience in which independent variables are manipulated, extraneous variables are held fixed, and in which the subject makes a phenomenal (...) judgement about the target experience of the investigation. I examine historical and contemporary examples of first-person experiments: Mariotte’s demonstration of the visual blind spot, Kanizsa’s subjective contours, the Tse Illusion, and investigations of the non-uniform resolution of the visual field. I discuss the role that phenomenal contrast plays in these methods, and how they overcome typical introspective errors. I argue that their intersubjective repeatability is an important factor in their scientific status, however, it is not the only factor. That they control for extraneous factors and confounds is another factor which sets them apart from pseudoscience (e.g., the perception of auras), and hence another reason for classifying them as genuine experiments. Furthermore, by systematically mapping out the structure of visual experience, these methods make scientific progress. Praises of such first-person experimental approaches may not always be sung by philosophers and psychologists, but they continue to flourish as respectable scientific methods nevertheless. (shrink)

Investing in research is a long-term, risky proposition. In agriculture, it could take fifteen years or more for a research finding to show an improvement in a farmer’s field. Yet, research institutions, like other organizations it needs to be evaluated. For more than twenty years, independent panels of outside experts have evaluated each of the international research centers that the Consultative Group of International Agricultural Research (CGIAR) supports. This paper examines the evolution of this review system, outlines the key methodological (...) challenges faced, and draws lessons for others engaged in evaluating research institutions. It notes that the scope of the CGIAR reviews have been broadened over time in response to users’ concerns. Reviews now cover four dimensions of performance: research results, quality and relevance of research, vision and strategic directions, and management efficiency. The methodological challenges faced in measurement, valuation, and attribution are reviewed, along with practices found to be helpful in addressing these concerns. The paper concludes that the panel approach to institutional evaluation has served CGIAR’s needs well, and recommends it as an evaluation technique for integrating quantitative and qualitative dimensions of institutional performance.

Reliability and external validity are two fundamental values that pose incompatible constraints on neurobiological experiments. The more reliability an experimental result achieves, the less external validity it earns, and vice versa. In this article, I propose an externalist interpretation of external validity: the external validity of an experimental result depends not only on how much complexity is built into an experimental design, but also on the relationship between the experimental result and other related experiments. This externalist interpretation, which explains how (...) a neurobiological experiment can be reliable and externally valid simultaneously, suggests a new way to understand the epistemology of neurobiological experimentation.

Deception is common in the marketplace where individuals pursue self-interests from their perspectives. Extant research suggests that perspective-taking, a cognitive process of putting oneself in other’s situation, increases consumers’ ethical tolerance for marketers’ deceptive behaviors. By contrast, the current research demonstrates that consumers who take the dishonest marketers’ perspective become less tolerant of deception when consumers’ moral self-awareness is high. This effect is driven by moral self-other differentiation as consumers contemplate deception from the marketers’ perspective: high awareness of the “moral (...) self” motivates consumers to distance themselves from the “immoral other.” The findings shed new light on how self-morality can vicariously shape social consideration in ethical judgments.

The purpose of this research report is twofold: First, we analyze a complex of attitudes about rape myths, adversarial sexual beliefs, and gender-role conservatism; and second, we evaluate the impact of rape-education intervention strategies on American college students' attitudes. Using the Solomon four-group design, we randomly assigned 14 classes of Sociology 101 students to three different treatment conditions: a live rape-education workshop, a video of the workshop, and a control group. We found significant gender differences in students' attitudes on all (...) the scales, with women being more knowledgeable about rape, less likely to blame the victim, and less accepting of adversarial sexual beliefs and gender-role conservatism. Most important, we found that within the limits of the study, rape-education intervention works in changing some attitudes about rape for both men and women students. We examine the impact of the different educational strategies and explore curricular implications, including the need to teach about rape within a feminist context. (shrink)

Skepticism toward the existence of neonatal differential imitation is fostered by views that assign it an excessive significance, making it foundational for social cognition. Moreover, a misleading theoretical framework may generate unwarranted expectations about the kinds of findings experimentalists are supposed to look for. Hence we propose a theoretical analysis that may help experimentalists address the empirical question of whether early differential imitation really exists. We distinguish three models of early imitation. The first posits automatic visuo-motor links evolved for sociocognitive (...) functions and we call it Genetically Programmed Direct Matching. The second is Meltzoff and Moore’s Active Intermodal Matching, which postulates a comparison between the acts of self and other. The third is the alternative we propose and we call it “Association by Similarity Theory”, as it relies on the tacit functioning of this domain-general process. AST describes early imitation merely as the differential induction or elicitation of behaviors that already tend to occur spontaneously. We focus on the contrast between AIM and AST, and argue that AST is preferable to AIM for two reasons. First, AST is more parsimonious and more plausible, especially because it does not require infants to be able to recognize self-other similarities. Second, whereas the extant findings tend to disqualify AIM, AST can account for them adequately. Furthermore, we suggest that AST has the potential to give new impulse to empirical research because it discriminates promising lines of inquiry from unproductive ones. (shrink)

How are we to appraise new technological developments that may bring revolutionary social changes? Currently this is often done by trying to predict or anticipate social consequences and to use these as a basis for moral and regulatory appraisal. Such an approach can, however, not deal with the uncertainties and unknowns that are inherent in social changes induced by technological development. An alternative approach is proposed that conceives of the introduction of new technologies into society as a social experiment. An (...) ethical framework for the acceptability of such experiments is developed based on the bioethical principles for experiments with human subjects: non-maleficence, beneficence, respect for autonomy, and justice. This provides a handle for the moral and regulatory assessment of new technologies and their impact on society. (shrink)

Accounting ethics failures have seized headlines and cost investors billions of dollars. Improvement of the ethical reasoning and behavior of accountants has become a key concern for the accounting profession and for higher education in accounting. Researchers have asked a number of questions, including what type of accounting ethics education intervention would be most effective for accounting students. Some researchers have proposed virtue ethics as an appropriate moral framework for accounting. This research tested whether Smithian virtue ethics training, based on (...) Adam Smith’s “The Theory of Moral Sentiments”, is effective in improving accounting student’s cognitive moral development. This research used a pre-test, treatment, post-test, quasi-experimental design utilizing the Defining Issues Test 2 instrument to measure students’ CMD. Analysis of DIT-2 gain scores did show a significant improvement in subjects’ personal interest scores and a significant improvement in an overall measure of CMD, the DIT N2 index, whereas their DIT-2 post-conventional scores did not improve significantly. This research supports the proposition that the concepts contained in Smithian virtue ethics can contribute to an effective accounting ethics education intervention. However, further research is required to determine what concepts should be included to improve accounting students’ post-conventional moral reasoning. (shrink)

Computer simulations show that an unstructured neural-network model [Shultz, T. R., & Bale, A. C. (2001).

Science, 283, 77–80], and generalizes to examples both outside and inside of the range of training sentences. Knowledge-representation analyses confirm that these networks discover that duplicate words in the sentences are nearly identical and that they (...) use this near-identity relation to distinguish sentences that are consistent or inconsistent with a familiar grammar. Recent simulations that were claimed to show that this model did not really learn these grammars [Vilcu, M., & Hadley, R. F. (2005). Minds and Machines, 15, 359–382] confounded syntactic types with speech sounds and did not perform standard statistical tests of results. (shrink)

Recent interest in the external validity of prediction models has produced many methods for finding predictive distributions that are invariant to dataset shifts and can be used for prediction in new, unseen environments. However, these methods consider different types of shifts and have been developed under disparate frameworks, making it difficult to theoretically analyze how solutions differ with respect to stability and accuracy. Taking a causal graphical view, we use a flexible graphical representation to express various types of dataset shifts. (...) Given a known graph of the data generating process, we show that all invariant distributions correspond to a causal hierarchy of graphical operators, which disable the edges in the graph that are responsible for the shifts. The hierarchy provides a common theoretical underpinning for understanding when and how stability to shifts can be achieved, and in what ways stable distributions can differ. We use it to establish conditions for minimax optimal performance across environments, and derive new algorithms that find optimal stable distributions. By using this new perspective, we empirically demonstrate that that there is a tradeoff between minimax and average performance. (shrink)

External validity is typically regarded as the downside of case study research by methodologists and social scientists; case studies, however, are often aimed at drawing lessons that are generalizable to new contexts. The gap between the generalizability potential of case studies and the research goals demands closer scrutiny. I suggest that the conclusion that case study research is weak in external validity follows from a set of assumptions that I term the "traditional view," which are disputable at best. In this (...) view, external validity is treated as a matter of mere representativeness. I argue that it is best understood instead as a problem of inference and that the emphasis should be placed on the comparability of the study rather than on the typicality of the case. By making case studies highly comparable, their external validity can be reliably and efficiently assessed and, in this way, their generalizability potential enhanced. (shrink)

A shared problem across the sciences is to make sense of correlational data coming from observations and/or from experiments. Arguably, this means establishing when correlations are causal and when they are not. This is an old problem in philosophy. This paper, narrowing down the scope to quantitative causal analysis in social science, reformulates the problem in terms of the validity of statistical models. Two strategies to make sense of correlational data are presented: first, a 'structural strategy', the goal of which (...) is to model and test causal structures that explain correlational data; second, a 'manipulationist or interventionist strategy', that hinges upon the notion of invariance under intervention. It is argued that while the former can offer a solution the latter cannot. (shrink)

Studies of knowledge utilization in public policy-making have important practical and theoretical implications. Accordingly, a voluminous work has been done on understanding and explaining the process of knowledge utilization (see Rich and Oh, 1993). However, we can easily find that there is the conspicuous absence of a greatly expanded understanding of the use of knowledge from those studies (Mandell and Sauter, 1984). Taken as a whole, empirical studies in the area of knowledge utilization have suffered from several critical problems (see (...) Rich, 1991; Oh, 1996a). More importantly, there appears to be serious conceptual and methodological gaps which need to be filled. This article focuses on one of the most significant methodological problems: measuring “knowledge utilization” from an evaluation perspective and offers some suggestions for future studies. (shrink)

In this paper I look at causality in the context of intervention research, and discuss some problems faced in the evaluation of causal hypotheses via interventions. I draw attention to a simple problem for evaluations that employ randomized controlled trials. The common alternative to randomized trials, the observational study, is shown to face problems of a similar nature. I then argue that these problems become especially acute in cases where the intervention is complex (i.e. that involves intervening in a complex (...) system). Finally, I consider and reject a possible resolution of the problem involving the simulation of complex interventions. The conclusion I draw from this is that we need to radically reframe the way we think about causal inference in complex intervention research. (shrink)

Francesco Guala once wrote that ‘The problem of extrapolation is a minor scandal in the philosophy of science’. This paper agrees with the statement, but for reasons different from Guala’s. The scandal is not, or not any longer, that the problem has been ignored in the philosophy of science. The scandal is that framing the problem as one of external validity encourages poor evidential reasoning. The aim of this paper is to propose an alternative—an alternative which constitutes much better evidential (...) reasoning about target systems of interest, and which makes do without consideration of external validity.

In The Poverty of Historicism, Karl Popper attacked a number of anti?naturalistic doctrines while advocating a program of piecemeal social reform. However, recent work in social science, and especially in the evaluation of social programs and social reforms, has exposed difficulties that have led many scientists to fall back on one or other of these same anti?naturalistic positions. It is suggested that Popper's strategy for dealing with anti?naturalism is no longer efficacious, although the difficulties in contemporary social science do not (...) warrant the abandonment of naturalism.

Insecticide resistance management (IRM) programme was launched in 26 cotton-growing districts of India in 2002 to rationalize the use of pesticides. The IRM strategy is presented within a full Integrated Pest Management (IPM) context with the premise that unless full-fledged efforts to understand all aspects of resistance phenomenon are made, any attempt to implement IPM at field level would not bear results. Unlike earlier IPM programmes, this programme is directly implemented by the scientists of state agricultural universities; thus the information (...) flow is directly from research subsystem to farmers. The extension methodology is different from IPM-farmer field school model, but much the same information is provided in didactic form, through active participation of the farmers throughout the cotton-growing season, by deploying scouts in villages. The knowledge gain of the farmers covered under IRM programme was measured by employing before/after quasi-experimental research design. The overall knowledge gain was significant in terms of identification of insect pests and natural enemies of cotton crop, proper use of insecticides and timely sowing of the crop, but farmers did not reach the desired level of knowledge with respect to other cultural practices, which result in suppression of pest buildup. In the absence of any effective bio-agents, the level of IPM integration is limited to cultural practices, thresholds, agro ecosystem analysis and use of insecticides according to good agricultural practices.

BACKGROUND: Representing is about theories and theory formation. Philosophy of science has a long-standing interest in representing. At least since Ian Hacking's modern classic Representing and Intervening analytical philosophers have struggled to combine that interest with a study of the roles of intervention studies. With few exceptions this focus of philosophy of science has been on physics and other natural sciences. In particular, there have been few attempts to analyse the use of the notion of intervention in other disciplines where (...) intervention studies are important, such as in nursing research. One unintended consequence of this is that the relations between representing and intervening tend to be less understood outside the natural sciences. OBJECTIVES AND DESIGN: This article highlights a number of possible topics on which nursing science and analytic philosophy of science can fruitfully interact. The basic idea is simple. Building on a characterisation of interventions in terms of what is intervened on and with respect to what, we suggest that interventions in nursing research typically are a blend of varieties belonging to the three dimensions of agency, epistemology, and ontology. The details of the blend determine the relation of the particular intervention study to traditional representational categories such as inductivism and hypothetico-deductive method, and have a bearing on its explanatory power and other more theory independent features of research as well. The framework we suggest should be relevant for nurse researchers who want to adopt a more general and analytically entrenched perspective on representing and intervening than the methodological boundaries in nursing research typically allow.

Recent advances in causal reasoning have given rise to a computational model that emulates the process by which humans generate, evaluate, and distinguish counterfactual sentences. Contrasted with the “possible worlds” account of counterfactuals, this “structural” model enjoys the advantages of representational economy, algorithmic simplicity, and conceptual clarity. This introduction traces the emergence of the structural model and gives a panoramic view of several applications where counterfactual reasoning has benefited problem areas in the empirical sciences.
