This article presents the development, validation and application of an instrument to measure everyday moral distress in different health care settings. The concept of moral distress has been discussed and developed over 20 years. A few instruments have been developed to measure it, predominantly in nursing. The instrument presented here consists of two factors: level of moral distress, and tolerance/openness towards moral dilemmas. It was tested in four medical departments and three pharmacies, where 259 staff members completed a questionnaire. The (...) two factors were found to be reliable. Differences in levels of moral distress were found between pharmacies and clinical departments, and between the youngest and oldest age groups; departmental staff and the youngest group experienced higher levels of moral distress. Departments reported less tolerance/openness towards moral dilemmas than pharmacies. The instrument needs to be tested further, but its strengths are the focus on everyday ethical dilemmas and its usefulness in different health care settings. (shrink)

The article advances a new way of thinking about classifications in general and the classification of mental disorders in particular. By applying insights from measurement practice to the context of classification, I defend a notion of epistemic accuracy that allows one to evaluate and improve classifications by comparing different classifying methods to each other. Progress in classification arises from the mutual development of classification systems and classifying methods. Based on this notion of accuracy, the article illustrates with an example how (...) psychiatric classifications can be improved via circumscribed comparisons of different perspectives on mental disorders, without relying on complete models of their complex aetiology. When applying this strategy, the traditional opposition between symptom-based and causal approaches is of little consequence for making progress in the epistemic accuracy of psychiatric classification.

For the successful achievement of evidence-based practice, clinicians, managers and purchasers need evidence on whether a particular intervention works and ways to judge the appropriateness of the outcome criteria and measures used. Guidance is needed on what outcome measure to use, especially within routine clinical care settings. Beginning with a re-clarification of the difference between a health status and an outcome measure, the paper presents an evaluative checklist for use by clinical audit and research staff to review outcome (...) class='Hi'>measures for use in routine care settings. Central features include the user-centredness of the measure, its psychometric properties, feasibility of use and utility. The applicability of the checklist is illustrated for outcome measurement in diabetes and stroke care. A modified form of the checklist is proposed for use by the busy clinician as an aid to the critical review of research papers within the context of evidence-based practice and to aid health care practitioners' choice of which outcome measure(s) to use within routine clinical care.

This article is about a start-up problem in scientific practice. Specifically, it is about the problem of justifying paleontological correlation—the practice of using fossils to establish time relations among fossiliferous rocks. Paleontological correlation was the key to assembling a geological timescale during the nineteenth century and remains an important practice in stratigraphic geology to this day. Yet contrary to philosophical expectations, this practice lacked a robust theoretical justification during the first half of the nineteenth century. This article examines what this (...) lack of justification amounted to, as well as how the method of paleontological correlation was justified in practice. (shrink)

Motivated by discourses that link early child development and health, nurses engage in seemingly benign surveillance of children. These practices are based on knowledge claims and technologies of developmental science, which remain anchored in assumptions of the child body as an incomplete form with a universal developmental trajectory and inherent potentiality. This paper engages in a critical discursive analysis, drawing on Donna Haraway's conceptualizations of technoscience and figuration. Using a contemporary developmental screening tool from nursing practice, this analysis traces the (...) effects of this tool through production, transformation, distribution, and consumption. It reveals how the techniques of imaging, abstraction, and measurement collide to fix the open, transformative child body in a figuration of the developing child. This analysis also demonstrates how technobiopower infuses nurses' understandings of children and structures developmentally appropriate expectations for children, parents, and nurses. Furthermore, it describes how practices that claim to facilitate healthy child development may inversely deprive children of agency and foster the production of normal or ideal children. An alternative ontological perspective is offered as a challenge to the individualism of developmental models and other dominant ideologies of development, as well as practices associated with these ideologies. In summary, this analysis argues that nurses must pay closer attention to how technobiopower infuses practices that monitor and promote child development. Fostering a critical understanding of the harmful implications of these practices is warranted and offers the space to conceive of human development in alternate and exciting ways. (shrink)

Psychology's tendency to focus on confirmatory analyses before ensuring constructs are clearly defined and accurately measured is exacerbating the generalizability crisis. Our growing use of digital behaviors as predictors has revealed the fragility of subjective measures and the latent constructs they scaffold. However, new technologies can provide opportunities to improve conceptualizations, theories, and measurement practices.

INTRODUCTION TOWARDS THE END OF THE PROTAGORAS Socrates suggests that the "salvation of our life" depends upon applying to pleasures and pains a science of measurement (metr$tik~techn~).Whether Plato intended to portray Socrates as putting forward sincerely the form of hedonism that makes these pleasures and pains relevant has been the subject of a detailed and probably (...) interminable debate, to which this paper will not directly contribute. By contrast, it seems to be supposed by almost all who have written on the topic that this hedonism, whoever is espousing it, puts forward pleasure as a single, homogeneous yardstick of value to serve as the basis of a supremely simple standard of choice. This standard simply directs one to seek the maximal amount of pleasure. The underlying supposition is that the hedonism put forward in the Protagorasallows one to define a maximum because all goods are commensurable. But, as I shall emphasize in the sequel, hedonism does not imply commensurability, nor does commensurability imply hedonism. The interpretive thesis of this essay is that the common presumption that the dialogue's hedonism carries commensurability with it has impeded our ability to understand the Protagor~'s relation to the other dialogues, and has distorted the fundamental purpose of Socrates's practical science. These matters are of more than textual interest. My reasons for trying to remain neutral as to the longstanding debate about attributing the dialogue's hedonism are not limited to wanting to avoid quagmires and remove confusions that have resulted from unwarranted interpretive assumptions. To many, the Protagorasis of tremendous importance as an early articulation of a calculative ideal for ethical or practical decisionmaking, whether or not Plato or Socrates was committed to that ideal. Looking [7] 8 JOURNAL OF THE HISTORY OF PHILOSOPHY 28:1 JANUARY x99 o back at the Protagorasfrom our twentieth-century perspective encourages the expectation that we might find there some argument for the crucial features of such a calculative ideal, as we have come to understand it. One such feature, prominent especially in the classical utilitarians, is that of the commensurability of goods, which in turn allows the precise definition of a maximizing rule. If the Protagoraspresented a calculative conception involving commensurability, then we might expect to find in the dialogue some argumentfor the rational necessity of commensurability. My claim will be that since there is no compelling evidence that the idea of commensurability is found in the dialogue, there is'hardly likely to be an argument for it there. In fact, it is of philosophical interest to see how far the arguments against weakness of will and for the unity of virtue (whoever is making them) can proceed without relying upon commensurability; This way of putting the philosophical points at issue here underlines the relative modesty of what I am claiming about commensurability. I argue that there is nothing in the dialogue that requires us to see commensurability as part of its hedonism, that the arguments proceed without relying upon commensurability, and that in some respects the problem of understanding the relationship of the Protagorasto Plato's other dialogues is eased if we refrain from attributing any commensurability here. I will show that a clearer picture of what is doing the argumentative work in the last secdon of the dialogue will result if we thus separate commensurability from hedonism, and that an illuminatingly different way of understanding the role of the science of measurement is thereby suggested. None of this amounts to a compelling argument that the idea of commensurability is not to be found in the dialogue. Rather, my case simply undermines the positive reasons for finding the idea there. Apart from the greater clarity which separating hedonism and commensurability allows, this modest negative case links up with the deeper philosophical moti,~ation I have mentioned by casting cold water on any hopes that the Protagorascould be made to yield an argument specifically linking commensurability to rationality.

Summary This paper explores the legacy of the great French experimental physicist Victor Regnault through the example of Gabriel Lippmann, whose engagement with electrical standardization during the early 1880s was guided by Regnault's methodological precept to measure ‘directly’. Lippmann's education reveals that the theoretical practice of ‘direct’ measurement entailed eliminating extraneous physical effects through the experimental design, rather than, like physicists in Britain and Germany, making numerical ‘corrections’ to measured values. It also provides, paradoxically, exemplars of the qualitative theoretical practices (...) that sustained Regnault's misguided ambition to avoid theory. By considering the largely negative reactions to Lippmann's proposals for selecting suitable electrical units and methods of measuring the ohm, this paper associates these theoretical practices with the ineffectual rhetorical strategies employed by Lippmann to promote his work, and thereby indicates that the practice of direct measurement was limited to French experimental physics. Whilst this result aligns readily with the existence of divergent nineteenth century British and German cultures of precision, it emerges from a very different disciplinary context in which the practice of precision electrical measurement developed independently of submarine telegraphy. This is because, as this paper illustrates, telegraphic engineering and experimental physics remained separate professions in France. (shrink)

I present a comparative and holistic method for qualitatively measuring sound ecological practice in chemistry. I consider chemicals developed and used by man from cradle to grave, that is, from the moment they are extracted from the earth, biomass, water or air, to their transportation, purification, mixing and elaboration in a factory, to their distribution by means of the market, to waste products both from the factory, packaging, transportations and by the consumer. I divide the locations of the ‘life’ of (...) the chemical into four spatio-temporal areas accordingly. I then use the ‘instituional compass’ method to determine a qualitative reading of the ecological soundness of the practice, where practice means the research, the adoption by industry and the distribution at scale on the market. The qualitative reading is in the form of an arrow on a trisected circle. The arrow holistically represents a table of data. The data can be economic, social or environmental. The arrow has a measurement: a degree and a length. The degrees, represent qualities spaning through: harmony, discipline and excitement. The length represents the importance, momentum or amplitude with which the quality is present. We use the compass method to compare the same product over time, or inter-substitutable, chemicals developed in different places, using different equipment or processes. In the conclusion, I discuss objectivity and science as they apply to the compass. (shrink)

This book addresses the challenges typical technical training managers, and other technical managers face in justifying the return on investment of their programs, particularly for large-scale, investment-intensive programs. This book describes a very intuitive and practical model for the measurement of the effectiveness of technical training programs. The book is based on a 4-tier Return on Effectiveness (ROE) model developed through years of research, observation, and experience. The ROE model uses four simple indices: training reaction index, improvement index, effectiveness (...) index, and impact trends to convey a full picture of the effectiveness of a training program. This feedback-based and data-based approach enables training managers with a step-by-step approach to collect data, measure important indicators and compute the indices to present evidence of the effectiveness of their training programs to the executives.

Non-cognitive dispositions have recently become psychological constructs of interest in the education, economics, philosophy, sociology, and psychology literature. In this article, I draw the distinction between property-first and measurement-first approaches to understanding the meaning of a particular non-cognitive disposition theoretical term, ‘grit’, as well as the relationship between this term and its corresponding measurement procedure. I argue that, depending on which approach one takes, one is confronted with different norms for judging the success of any disposition-measurement procedure pair, meaning that (...) the difference in philosophical approaches may have practical import. I argue that the measurement-first approach is the one educators and educational policy-makers ought to adopt towards grit as it is less likely to lead to over-valuing grit in situations where a gritty disposition may be harmful, better respects scientific virtues and values, and provides a clearer understanding of grit than the property-first approach.

Wisdom, long a topic of interest to moral philosophers, is increasingly the focus of social science research. Philosophers have historically been concerned to develop a rationally defensible account of the nature of wisdom and its role in the moral life, often inspired in various ways by virtue theoretical accounts of practical wisdom (phronesis). Wisdom scientists seek to, among other things, define wisdom and its components so that we can measure them. Are the measures used by wisdom scientists actually (...) measuring what philosophers have in mind when they discuss practical wisdom? I argue that they are not. Contemporary measures of wisdom and its components may pick out some necessary prerequisites of practical wisdom, but they do not measure a philosophically plausible practical wisdom or its components. After explaining the argument and defending it against objections, I consider its implications. Should wisdom scientists ignore the philosophical conception of practical wisdom in favor of other conceptions, revise their methods to try to measure it, or continue the interdisciplinary study of practical wisdom without expecting to measure it? I make a preliminary argument for the third option. (shrink)

In this paper, I argue for a distinction between two scales of coordination in scientific inquiry, through which I reassess Georg Simon Ohm’s work on conductivity and resistance. Firstly, I propose to distinguish between measurement coordination, which refers to the specific problem of how to justify the attribution of values to a quantity by using a certain measurement procedure, and general coordination, which refers to the broader issue of justifying the representation of an empirical regularity by means of abstract mathematical (...) tools. Secondly, I argue that the development of Ohm’s measurement practice between the first and the second experimental phase of his work involved the change of the measurement coordination on which he relied to express his empirical results. By showing how Ohm relied on different calibration assumptions and practices across the two phases, I demonstrate that the concurrent change of both Ohm’s experimental apparatus and the variable that Ohm measured should be viewed based on the different form of measurement coordination. Finally, I argue that Ohm’s assumption that tension is equally distributed in the circuit is best understood as part of the general coordination between Ohm’s law and the empirical regularity that it expresses, rather than measurement coordination.

The present study describes the development of an ongoing and systematic index to measure consumers’ sentiments towards business ethical practices. The Business Ethics Index (BEI) is based on the well established measurements of consumer sentiments, namely the ICS (Index of Consumer Sentiment) and CBCCI (Conference Board Consumer Confidence Index). The BEI is comprised of 4 measurements representing the dimensions of “personal-vicarious” and “past-future.” Data from 503 telephone interviews were used to calculate a BEI of 107. This indicates an overall positive (...) consumer sentiment towards the ethical behavior of business. Future calculations of the BEI are planned which will allow for the estimation of the latent dynamics of trends in consumer sentiments toward American business ethics. (shrink)

Physiological observations or vital sign monitoring is a fundamental tenet of nursing care within an acute care setting. Surveillance of vital signs with algorithmic early warning frameworks aids the nurse in monitoring for early symptoms of clinical deterioration. The nurse must be cognizant of the factors that can influence the vital sign measurements because the framework score is only as reliable as the data inserted. Vital sign technology has made significant progress in its ability to objectify nursing subjective assessments. Early (...) scientists have struggled with its relationship with subjectivity, claiming it has no relevance in true science. Quantitative measurements, regardless of how objectively they were created or obtained, need a subjective lens to interpret and act on the results. The skill of “making” the vital signs can be easily taught or done with technology, but it is the “taking” of the data for analysis of truth and action that requires a higher level of expertise. This paper will examine the truth of vital sign methodology and monitoring to explore the question, “Is true objectivity in the nursing practice of vital sign measurement possible?” The truth in vital sign recognition through a subjective lens will also be explored to challenge the philosophical scientific claims that objective data are the absolute truth.

The instrumental character of Francis Bacon’s natural and experimental histories was often noted, but never fully investigated. In this paper I aim to reconstruct the theoretical and methodological background which supports this feature. I claim that we can read large parts of the second book of Bacon’s Novum organum as a guide to laboratory practices; and that it was read in this manner by some of Bacon’s seventeenth century followers. Key to this guide is Bacon’s theory of prerogative instances which, (...) in turn, provides the grounding for a whole theory of instruments of detection and instruments of measurement. I show, in particular, how Bacon suggested that such instruments can be used for ‘charting’ virtues and powers; a process in which instruments of detection can be transformed into instruments of measurement. I also show that Bacon’s views on instruments entail an elaborated conception of measurement which departs from the ethos of artisanal perfection. Instead of pursuing the ‘best results’, Bacon’s instrumental natural and experimental histories aim to offer a large enough corpus of correlations, estimates and calculations which, taken together, can represent more or less accurately changes and variations of natural virtues and powers.

This paper distinguishes between two arguments based on measurement robustness and defends the epistemic value of robustness for the assessment of measurement reliability. I argue that the appeal to measurement robustness in the assessment of measurement is based on a different inferential pattern and is not exposed to the same objections as the no-coincidence argument which is commonly associated with the use of robustness to corroborate individual results. This investigation sheds light on the precise meaning of reliability that emerges from (...) measurement assessment practice. In addition, by arguing that the measurement assessment robustness argument has similar characteristics across the physical, social and behavioural sciences, I defend the idea that there is continuity in the notion of measurement reliability across sciences.

This paper examines the role existence plays in measurement validity. I argue that existing popular theories of measurement and of validity follow a correspondence framework, which starts by assuming that an entity exists in the real world with certain properties that allow it to be measurable. Drawing on literature from the sociology of measurement, I show that the correspondence framework faces several theoretical and practical challenges. I suggested the validity-first framework of measurement, which starts with a practice-based validation process (...) as the basis for a measurement theory, and only posits objective existence when it is scientifically useful to do so.

ArgumentTwo simultaneous episodes in late nineteenth-century mathematical research, one by Karl Hermann Brunn and another by Hermann Minkowski, have been described as the origin of the theory of convex bodies. This article aims to understand and explain how and why the concept of such bodies emerged in these two trajectories of mathematical research; and why Minkowski's – and not Brunn's – strand of thought led to the development of a theory of convexity. Concrete pieces of Brunn's and Minkowski's mathematical work (...) in the two episodes will, from the perspective of the above questions, be presented and analyzed with the use of the methodological framework of epistemic objects, techniques, and configurations as adapted from Hans-Jörg Rheinberger's work on empirical sciences to the historiography of mathematics by Moritz Epple. Based on detailed descriptions and a comparison of the objects and techniques that Brunn and Minkowski studied and used in these pieces it will be concluded that Brunn and Minkowski worked in different epistemic configurations, and it will be argued that this had a significant influence on the mathematics they developed for those bodies, which can provide answers to the two research questions listed above.

Ecologically valid procedures for eliciting and measuring children's anger are needed to enhance researchers' theories of children's emotional competence and to guide intervention efforts aimed at reactive aggression. The purpose of this article is to describe a laboratory-based game-playing procedure that has been used successfully to elicit and measure children's anger across observational, physiological, and self-report channels. Steps taken to ensure that participants are treated ethically and fairly are discussed. The article highlights recently published data that emphasize the importance of (...) provoking and assessing children's anger across multiple channels using laboratory-based procedures. Finally, it presents preliminary data that suggest that the safeguards taken to protect children were successful in making both children and their parents feel well treated and comfortable. (shrink)

Following a detailed review of the accomplishments and aspirations of the Journal of Research Practice, we have undertaken a restructuring of the editorial board, with inputs from people associated with this journal. In designing the new structure, we have taken into account the need for building the journal’s profile in the six focus areas recently clarified: (1) Research Applications, (2) Research Spaces, (3) Research Education, (4) Research Experiences, (5) Research Philosophy, and (6) Research on Research. Focus Editors will ensure that (...) the journal remains well engaged with the developments in these focus areas. The new structure allows us to involve all contributors to the journal in playing a role to enhance the journal’s relevance to researchers and reflective professionals. This restructuring exercise has presented us with an opportunity to build on the strengths of the journal and address areas of concern so as to strengthen the journal’s quality, relevance, and impact. A review of different notions of impact has led us to a set of proposed measures for enhancing the relevance and utilisation of the journal in future. (shrink)

I flesh out the sense in which the informational approach to interpreting quantum mechanics, as defended by Pitowsky and Bub and lately by a number of other authors, is (neo-)Bohrian. I argue that on this approach, quantum mechanics represents what Bohr called a “natural generalisation of the ordinary causal description” in the sense that the idea (which philosophers of science like Stein have argued for on the grounds of practical and epistemic necessity) that understanding a theory as a theory (...) of physics requires that one be able to “schematise the observer” within it is elevated in quantum mechanics to the level of a postulate in the sense that interpreting the outcome of a measurement interaction, as providing us with information about the world, requires as a matter of principle, the specification of a schematic representation of an observer in the form of a ‘Boolean frame’—the Boolean algebra representing the yes-or-no questions associated with a given observable representative of a given experimental context. I argue that the approach’s central concern is with the methodological question of how to assign physical properties to what one takes to be a system in a given experimental context, rather than the metaphysical question of what a given state vector represents independently of any context, and I show how the quantum generalisation of the concept of an open system may be used to assuage Einstein’s complaint that the orthodox approach to quantum mechanics runs afoul of the supposedly fundamental methodological requirement to the effect that one must always be able, according to Einstein, to treat spatially separated systems as isolated from one another.

Measuring the effectiveness of medical interventions faces three epistemological challenges: the choice of good measuring instruments, the use of appropriate analytic measures, and the use of a reliable method of extrapolating measures from an experimental context to a more general context. In practice each of these challenges contributes to overestimating the effectiveness of medical interventions. These challenges suggest the need for corrective normative principles. The instruments employed in clinical research should measure patient-relevant and disease-specific parameters, and should not (...) be sensitive to parameters that are only indirectly relevant. Effectiveness always should be measured and reported in absolute terms (using measures such as 'absolute risk reduction'), and only sometimes should effectiveness also be measured and reported in relative terms (using measures such as 'relative risk reduction')-employment of relative measures promotes an informal fallacy akin to the base-rate fallacy, which can be exploited to exaggerate claims of effectiveness. Finally, extrapolating from research settings to clinical settings should more rigorously take into account possible ways in which the intervention in question can fail to be effective in a target population.

General practice consultation has often been characterized by pragma-dialecticians as an argumentative activity type. These characterizations are typically derived from theoretical insights and qualitative analyses. Yet, descriptions that are based on quantitative data are thus far lacking.

It describes the implementation and preliminary results of a content analysis of seventy videotaped medical consultations of which the extent and type (...) of doctors’ argumentative support for medical opinions and advice are analyzed. Based on the study results, this paper addresses the merits of observational studies using content analysis as a method for the analysis of argumentative discourse in context as well as some of its key challenges and limitations, laying bare the opportunities for future research.

One of the most challenging questions surrounding subjective animal welfare is whether these states are measurable: that is, is subjective welfare an appropriately quantifiable target for scientific enquiry and ethical and deliberative calculation? The availability of several different types of measurement scale raises important questions regarding whether subjective experience has the right properties to be meaningfully represented on the types of scale required for different applications. This methodological question has so far received scant attention in the animal welfare literature. In (...) this paper, I address this omission by examining the types of measurement scale we can reasonably expect to apply to animal welfare measurements, and which we will actually need for our applications. I argue that our different applications will require variously ordinal, interval, and ratio scales, and that we have sufficient reason to believe that subjective welfare is a target with the appropriate characteristics to justify the practice of representing it using each of these types of scales.
