Ofsted requires UK schools to help students understand the working world and gain employability skills. However, the aims of education are much broader: Education should enable flourishing long after leaving school. Therefore, students’ career decisions should be conducive to long-term flourishing beyond career readiness and educational attainment. In this mixed-methods study, we asked a representative sample of UK adults to reflect on their career decision-making processes at school and at university. We also measured current levels of self-reported objective (e.g., (...) financial security) and subjective (e.g., subjective well-being) flourishing. The open-ended career decision reflections were coded for three moral reasoning strategies: virtue ethical, consequentialist, and deontological. Using correlations and structural equation modelling, we examined the association between the propensity for using each moral reasoning strategy in past career decisions and current flourishing. Virtue ethical moral reasoning in relation to career decision-making predicted aspects of flourishing most strongly and frequently. Consequentialist reasoning weakly and infrequently positively predicted aspects of flourishing. Deontological reasoning either did not predict flourishing at all, or negatively predicted flourishing. Our results suggest that the reasoning strategy behind career decisions people take in school or university is important to consider in UK careers provision, and current best practice. (shrink)

Social desirability bias is a pervasive measurement challenge in the social sciences and survey research. More clarity is needed to understand the performance of social desirability scales in diverse groups, contexts, and cultures. The present study aims to contribute to the international literature on social desirability measurement by examining the psychometric performance of a short version of the Marlowe-Crowne Social Desirability Scale in a nationally representative sample of teachers in Kazakhstan. A total of 2,461 Kazakhstani teachers completed the MCSDS (...) – Form C in their language of choice. The results failed to support the theoretical unidimensionality of the original scale. Instead, the results of Random Intercept Item Factor Analysis model suggest that the scale answers depend more on the method factor rather than the substantial factor that represents SDB. In addition, an alternative explanation indicates that the scale seems better suited to measuring two SDB correlated factors: attribution and denial. Internal consistency coefficients demonstrated unsatisfactory reliability scores for the two factors. The Kazakhstani version of the MCSDS – Form C was invariant across geographic location, language, and partially across age groups. However, no measurement invariance was demonstrated for gender. Despite these limitations, the analysis of the Kazakhstani version of the MCSDS – Form C presented in this study constitutes a first step in facilitating further research and measurement of SDB in post-Soviet Kazakhstan and other collectivist countries.

Perfectionism is a multidimensional construct with both positive and negative aspects. Recently, the concept of appearance-oriented perfectionism has been introduced, which is associated with body image dissatisfaction and weight and shape control behaviors. The Physical Appearance Perfectionism Scale is a 12-item two-factor instrument developed to assess this new dimension of perfectionism. The aim of the study is to validate the Spanish version of PAPS among a representative sample of 850 male university students in Spain. Exploratory and confirmatory factorial structure, (...) internal consistency, convergent and concurrent validity, and associated predictor variables analyses have been carried out. Results showed that the Spanish version of the PAPS maintains the original factor structure with all items and proves to be a reliable instrument. Physical appearance-oriented perfectionism is associated with general perfectionism, higher body dissatisfaction, Eating Disorders and Muscle Dysmorphia symptomatology, and compulsive exercise, particularly in the Worry about Imperfection subscale. These variables also act as predictors of physical appearance perfectionism. The use of the PAPS-S and the analysis of its subscales is recommended in the context of body image-related pathologies such as Eating Disorders and Muscle Dysmorphia. (shrink)

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being (...) enhancement. Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

Many adolescents use their electronic devices to send each other sexually explicit texts, photos, and videos of themselves—commonly known as sexting. This can be fun and is not usually problematic. However, if the intended recipient decides to share these sexts with a broader audience, the consequences for the depicted can be detrimental. The purpose of this study was to investigate the prevalence of sext-sharing among Dutch adolescents and explore the characteristics of those who do, to gain a better understanding of (...) factors involved in dissemination. We used data from “Sex under the age of 25,” a representative national survey on sexual health among a sample of 20,834 Dutch 12–24-year-olds. The prevalence of sext-sharing was estimated using Complex Samples. Logistic regressions were used to assess associations between demographics, school-based sexting education, sexual- and online behavior, and mental health and sext-sharing. About 4% of the adolescents reported having shared someone else's sext in the last six months. Being male, aged 12–14 years, frequent social media usage, watching online porn, sexual experience, and being subjected to sext-sharing themselves associated most strongly with sext-sharing. Our findings show that the likelihood of sext-sharing is lower in older adolescents and that it associates with the extent of adolescents' sexual curiosity and online activity. The overlap between sharing sexts of others and having one's own sext shared suggests that dissemination of personal sexual content might be normalized or used as an act of retribution. Further research could be helpful to explain the mechanisms underlying this overlap. The results of this study illustrate the importance of exposing adolescents to evidence based preventive educational interventions on sexting from 12 years onwards and not just within the context of traditional school-based sex education, but also as a part of the media-literacy curriculum.

Neural engineering technologies such as implanted deep brain stimulators and brain-computer interfaces represent exciting and potentially transformative tools for improving human health and well-being. Yet their current use and future prospects raise a variety of ethical and philosophical concerns. Devices that alter brain function invite us to think deeply about a range of ethical concerns—identity, normality, authority, responsibility, privacy, and justice. If a device is stimulating my brain while I decide upon an action, am I still the author of the (...) action? Does a device make the interiority of my experience accessible to others? Will the device change the way I think of myself and others think of me? Such fundamental questions arise even when a device is designed for only a relatively circumscribed purpose, such as restoring functioning via a smart prosthetic. We are part of a National Science Foundation-funded Engineering Research Center tasked with investigating philosophical and social implications of neural engineering research and technologies. Neural devices already in clinical use, such as deep brain stimulators for Parkinson's disease or essential tremor, have spurred healthy debate about such implications. Devices currently under development—such as the BrainGate System of implanted brain sensors coupled to robotics in persons with paralysis, exoskeletons for augmented movement, transcranial do-it-yourself stimulators, closed-loop brain stimulating systems, or even brain-to-brain interfacing—promise to extend and deepen these debates. At our center, brain-computer interfaces are the principal focus of work. Even acknowledging that the clinical translation of neural devices and seamless integration by end users may still largely reside in the future, the potential these devices hold calls for careful early analysis. The launching of the Brain Research through Advancing Innovative Neurotechnologies Initiative in April 2013 provides further impetus for this work. (shrink)

With right-wing-extremist and -populist parties and movements on the rise throughout the world, the concept of authoritarianism has proven to be particularly valuable to explain the psychological underpinnings of these tendencies. Even though many scales to measure the different dimensions of authoritarianism exist, no short screening instrument has been tested and validated on a large scale so far. The present study examines the psychometric properties of the screening instrument Authoritarianism – Ultrashort in three representative German samples. Using exploratory (...) and confirmatory factor analysis, the A-US demonstrated acceptable internal consistency. Model fit was good and correlations with related constructs indicated convergent validity in both samples. Construct validity was demonstrated using the original version of the scale. The instrument proved to be invariant across sex, employment status, and education, but not across different age groups. Finally, the analyses showed that differences in the A-US are associated with sociodemographic variables. Potential causes and effects of these findings are discussed. Based on these results, the A-US proved to be a valuable and highly efficient tool to screen for authoritarian tendencies. (shrink)

In this article, the insertion of a two-staged highly interesting question in an online, survey-based field experiment is shown to produce better survey completion rate (i.e., decreases completion refusal by 8%) and sample representativeness (increases the number of moderate answer patterns by 12%) than a typical (same) highly interesting question at the beginning of a survey only. Using nonparametric tests and subgroup probability analysis, measured effects include survey completion rates, response bias and reported demographic differences. In regards to sample representativeness, (...) the results also raise questions about the sensitivity of the conventional practice of comparing early to late respondent means scores as a method of investigating nonresponse bias in marketing research. Alternative approaches to measuring potential non-response bias are compared with the tradition of comparing early-wave verses late-wave mean respondent differences. The results indicate that the conventional mean test fails to identify differences in nonresponse bias; the scores of highly interested or opposed respondents in the first waves produce equivalent means to the scores of the less interested or opposed respondents in the latter wave between the surveys (e.g., 1's and 5's vs. 2's and 4's, both averaging to 3's) that are identifiable through kurtosis and probability analysis.

BackgroundThe aim of the study was to explore symptoms of anxiety and depression, insomnia, and quality of life in a Norwegian community sample of older adults.MethodsA representative sample was drawn from home-dwelling people of 60 years and above, living in a large municipality in Norway.ResultsBased on established cut-off scores, 83.7% of the participants showed no symptoms of anxiety/depression, 12% had mild symptoms, 2.7% moderate symptoms, 1.5% showed severe symptoms of anxiety/depression. A total of 18.4% reported insomnia symptoms. Regarding health-related (...) quality of life, few participants reported problems with self-care, but pain and discomfort were common. Depression/anxiety, insomnia, and health-related quality of life showed moderate to strong associations.DiscussionThe results suggest a close interplay between anxiety/depression, insomnia, and health-related quality of life in older adults.

The social sciences face a problem of sample non-representation, where the majority of samples consist of undergraduate students from Euro-American institutions. The problem has been identified for decades with little trend of improvement. In this paper, I trace the history of sampling theory. The dominant framework, called the design-based approach, takes random sampling as the gold standard. The idea is that a sampling procedure that is maximally uninformative prevents samplers from introducing arbitrary bias, thus preserving sample representation. I show (...) how this framework, while good in theory, faces many challenges in application. Instead, I advocate for an alternative framework, called the model-based approach to sampling, where representative samples are those balanced in composition, however they were drawn. I argue that the model-based framework is more appropriate in the social sciences because it allows for systematic assessment of imperfect samples and methodical improvement in resource-limited scientific contexts. I end with practical proposals of improving sample quality in the social sciences. (shrink)

The text defines the fundamental terms relevant to the process of sampling, elaborates the characteristics of individual samples, selection strategies, and the key methodological issues and dilemmas of the researchers during the procedures of sampling. The selection of a sample is an essential aspect when planning the methodology of empirical research and has a key role in ensuring the reliability and validity of research results. Researchers should carefully consider the characteristics of the population and the specific research objectives and (...) accordingly choose the sampling strategy. Representative samples minimize bias and provide a higher level of confidence when generalizing results to a larger population. Non-representative samples are valuable when the selection of a representative sample is impractical or impossible. They involve different forms of bias but offer flexibility, cost-effectiveness and practicality. Non-representative samples are applicable in qualitative studies and in the research with populations that are hard to reach. However, it is important to be aware of their limitations and the justification for generalization findings outside the specific sample. Regardless of the used strategy, researchers must strive for transparency, clearly documenting the unit selection procedure and stress the potential limitations as key elements to ensure the reliability and validity of the research results.

In this chapter we offer a reflection on the notion of sample representativeness from an interpretivist-qualitative perspective. Specifically we are looking into the idea of learning about a phenomenon through examining extraordinary individuals characterized by that phenomenon; to describe them we use the term ‘extraordinary’ as a noun, thereby building on Howard Gardner’s notion of ‘extraordinary minds’ (Gardner, 1997). We are looking at the ‘extraordinary’ in their professional socio-historical contexts, as the phenomena we are interested in cannot be divorced from (...) the contexts in which they are embedded. In this particular book chapter we are interested in the phenomenon of creativity, and the two research projects on which we base our argument are also concerned with creativity. However, we do not see any reason why similar considerations could not be made in other areas – but we do not suggest that a simple generalizability is possible. -/- The basis of our reflection are two research projects we have done in the past: In the first one, we conducted ‘insider interviews’ (the second-named author used to be a chef in Michelin-starred restaurants) with 18 extraordinary chefs in order to gain a better understanding of how creativity manifests itself socio-culturally in the culinary domain (Cousins, O’Gorman, & Stierand, 2010; Stierand, 2015; Stierand & Dörfler, 2012b, 2016; Stierand, Dörfler, & MacBryde, 2014; Stierand & Lynch, 2008). In the second one, we interviewed 20 extraordinary scientists, including 17 Nobel Laureates in order to gain a better understanding of cognitive complexity and how cognitive complexity is manifested in the socio-cultural acceptance of creative outcomes in the scientific world (Dörfler & Eden, 2014a, 2014b, 2017). -/- We have presented our research at various conferences, and, perhaps as we were so passionate about it, we have received a great deal of interest from others, mainly PhD students and early career researchers, who were keen to undertake similar research projects. But, although we believe that the methodological journey we have taken can be an excellent path to very interesting and meaningful research, we cannot wholeheartedly recommend it to junior colleagues, knowing the difficulties they will face when trying to justify their findings and methodological choices and the uncertain profits in the form of publication of the results (see an excellent overview of the difficulties and profits in Lebuda, 2014). We made our initial methodological choices, i.e. interviewing extraordinary chefs and scientists, purely intuitively that is, we just knew that the insights we could gain from these people would potentially lead to excellent findings. However, this is not an acceptable justification in the academic world. Therefore, we started to develop a framework for conducting this type of research, but we are not quite there yet. This reflection chapter is a midway point for taking stock of the convincing arguments we have developed over time and of the problems we still need to solve. (shrink)

This article provides insight into one form of audience involvement with celebrities: parasocial relationships. To address several shortcomings in PSR research – focus on TV, confusion between PSI and PSR, use of student samples, neglect of socio-demographic variables – a representative online survey was conducted with 1000 Flemish adults who indicated 382 celebrities as favorites. A new scale reveals that PSR contain two important elements: emotional connections and an analogy with social relationships. Confirming previous research, most favorite celebrities (...) are male, and cultural proximity is especially important for older respondents. In one combined model, respondents’ and celebrities’ characteristics are included as potential PSR predictors. This model nuances previous research and reveals that people who are male, older, more lowly-educated, and interested in celebrity news have stronger PSR. Further, stronger PSR are found for local and religious, political, sports, and music celebrities than for film celebrities. (shrink)

ArgumentMoreau (2019) has raised concerns about the use of DNA data obtained from vulnerable populations, such as the Uighurs in China. We discuss another case, situated in Europe and with a research history dating back 100 years: genetic investigations of Roma. In our article, we focus on problems surrounding representativity in these studies. We claim that many of the circa 440 publications in our sample neglect the methodological and conceptual challenges of representativity. Moreover, authors do not account for problematic misrepresentations (...) of Roma resulting from the conceptual frameworks and sampling schemes they use. We question the representation of Roma as a “genetic isolate” and the underlying rationales, with a strong focus on sampling strategies. We discuss our results against the optimistic prognosis that the “new genetics” could help to overcome essentialist understandings of groups. (shrink)

Intentional sampling methods are non-probabilistic procedures that select a group of individuals for a sample with the purpose of meeting specific prescribed criteria. Intentional sampling methods are intended for exploratory research or pilot studies where tight budget constraints preclude the use of traditional randomized representative sampling. The possibility of subsequently generalize statistically from such deterministic samples to the general population has been the issue of long standing arguments and debates. Nevertheless, the intentional sampling techniques developed in this paper (...) explore pragmatic strategies for overcoming some of the real or perceived shortcomings and limitations of intentional sampling in practical applications.

Many ethical frameworks require artificial intelligence (AI) systems to be explainable. Explainable AI (XAI) models are frequently tested for their adequacy in user studies. Since different people may have different explanatory needs, it is important that participant samples in user studies are large enough to represent the target population to enable generalizations. However, it is unclear to what extent XAI researchers reflect on and justify their sample sizes or avoid broad generalizations across people. We analyzed XAI user studies (N (...) = 220) published between 2012 and 2022. Most studies did not offer rationales for their sample sizes. Moreover, most papers generalized their conclusions beyond their target population, and there was no evidence that broader conclusions in quantitative studies were correlated with larger samples. These methodological problems can impede evaluations of whether XAI systems implement the explainability called for in ethical frameworks. We outline principles for more inclusive XAI user studies.

Sample preparation is the process of altering a naturally occurring object into a representative form that is amenable to scientific inquiry. Preparation is an important preliminary to data collection, ubiquitous in the life sciences and elsewhere, yet relatively neglected in historical and philosophical literature. This paper presents a detailed historical case study involving the preparation and study of blood crystals in the nineteenth century. The case is used to highlight significant features of preparation, which aid our understanding of the (...) epistemology of sciences in which preparations play an important role. First, it shows the role of technical knowledge in efforts to characterize a scientific phenomenon or object of interest. Especially in early stages of characterization, scientists improve their understanding of what they are preparing by better understanding their preparation procedures. Second, this case contributes to recent views of characterization as a relatively autonomous domain of scientific activity. It shows how preparation functions as a site for integrating different experimental methods, and the difficulties that ensue. In light of these considerations, the case shows how characterization is capable of shaping or constraining explanatory pursuits as much as it is guided by them. (shrink)

It is increasingly common in cognitive science and philosophy of perception to regard perceptual processing as a probabilistic engine, taking into account uncertainty in computing representations of the distal environment. Models of this kind often postulate probabilistic representations, or what we will call probabilistic states,. These are states that in some sense mark or represent information about the probabilities of distal conditions. It has also been argued that perceptual experience itself in some sense represents uncertainty (Morrison _Analytic Philosophy_ 57 (1): (...) 15 48, 2016 ). In this article, we will first consider three models of sensory activity from perceptual neuroscience, namely signal detection theory (SDT), probabilistic population codes (PPC), and sampling. We will then reflect on the sense in which the probabilistic states introduced in these models are probabilistic representations. To sharpen this discussion, we will compare and contrast these probabilistic states to credences as they are understood in epistemology. We will suggest that probabilistic representation, in an appropriately robust sense, can be understood as a form of analog representation. In the last part of the paper, we apply this to the issue of whether conscious experience represents uncertainty—we will interpret this as the claim that there are phenomenal features of experience that serve as analog probabilistic representations.

Students in 80 kindergarten to grade six classrooms photographed and captioned experiences in class which they identified as examples of democratic citizenship education. With the assistance of a teacher candidate placed in their classroom for a semester, students chose and captioned five of the photographs they considered to best represent demonstrate citizenship education. Four main categories of citizenship events emerged describing key elements associated with democratic citizenship education; shared decision making, participating in a learner-oriented classroom context in which students have (...) some individual choice of daily activities, equality of opportunity, and activities extending into the community and integrating community and classroom. Early grades students (K-3) identified activities they associated with democratic citizenship education while upper grades (4-6) students additionally presented rationales and gave evidence to support their representations. Empowerment, problem solving, and contributing to the common good were additional elements associated with democratic citizenship education in the classes sampled, although these were not strongly represented as were the four key elements. This study provides an initial portrait indicating a need for deeper investigation of K-6 students' own representations of the democratic citizenship education they experience. (shrink)

We advance a theory of the representational role of Euclidean diagrams according to which they are samples of co-exact features. We contrast our theory with two other conceptions, the instantial conception and Macbeth’s iconic view, with respect to how well they accommodate three fundamental constraints on theories of the Euclidean diagrammatic practice— that Euclidean diagrams are used in proofs whose results are wholly general, that Euclidean diagrams indicate the co-exact features that the geometer is allowed to infer from them (...) and that Euclidean diagrams play the same role in both direct proofs and indirect proofs by reductio—and argue that our view is the one best suited to account for them. We conclude by illustrating the virtues of our conception of Euclidean diagrams as samples by means of an analysis of Saccheri’s quadrilateral. (shrink)

Subjective probability plays an increasingly important role in many fields concerned with human cognition and behavior. Yet there have been significant criticisms of the idea that probabilities could actually be represented in the mind.

The resulting view answers to some of the most well known criticisms of subjective probability, and is also supported by empirical work in neuroscience and (...) behavioral psychology. The repercussions of the view for how we conceive of many ordinary instances of subjective probability, and how it relates to more traditional conceptions of subjective probability, are discussed in some detail.

University students are at elevated risk for psychological distress, especially during the COVID-19 pandemic. The aim of this study was to warmly contact our students and investigate the psychological impact of the COVID-19 pandemic on the subjective wellbeing and levels of psychological symptoms of university students in Belgium. All bachelor and master students of the Vrije Universiteit Brussels were invited for a brief structured telephone interview in March, 2021. In total, 7,154 students were assessed by a structured interview, based on (...) the Kessler Psychological Distress Scale and the Anamnestic Comparative Self-Assessment. Compared to a representative sample, students considered their life during the pandemic as less satisfying compared to their life before the pandemic. Overall, all students have suffered from COVID-19 and the measures taken to contain the pandemic. Twenty percent of our sample of 7,154 VUB students scored above the K6 cutoff, indicating a heightened risk for having a diagnosable mental illness severe enough to cause functional limitations and to require treatment. This study highlights the need for psychological support for all students, during the COVID-19 pandemic. (shrink)

Why was Hensen unsuccesful in the quantification of ecological sampling? No aspect of plankton research itself seems to have hindered quantification; both collecting methods and taxonomy were sufficiently advanced. The reason is probably that at the time he began sampling, Hensen had to devise his own statistical methods for expressing the reproducibility and validity of samples. Hensen might have succeeded in this if he had overcome prevalent nineteenth-century attitudes toward randomness.The statistical literature of medicine and physics with which Hensen (...) was probably familiar gave methods for expressing reproducibility and for comparing differences between means of different sets of observations. For example, a student of Poisson writing on medical statistics advocated using Poisson's limit (standard error 2√2) to test the difference between two means56. Other authors suggested that differences between means were most meaningful if very large numbers of observations were used.57 In his laboratory subsampling, Hensen used the propable error as a limit about means. In this and other ways, he seems most indebted to the physicist Ernst Abbe for statistical methods.58 However, all the methodology available to Hensen had been developed for situations in which errors are a property of the measurement or sampling process, and not of the phenomena themselves. The available methods for measuring reproducibility were based on the assumption that differences from the average were small and that they tended to accumulate about the mean in a bell-shaped pattern. Hensen constantly reinvestigated the distribution of plankton numbers about the average using a different method each time. Westergaard points out that medical statisticians did not make such investigations with their biological data.59To a considerable extent, biological sampling problems forced development of theory because samples afforded the only information on a pattern in water or soil which could not be directly observed. The sampling methods of Laplace and the late nineteenth-century government statisticians contrasted strongly with Hensen's because, either through subjective knowledge of the population sampled or through censuses, they attempted to choose representative or typical samples.60 The high reproducibility and validity of representative sampling is attained by knowing more about a population than a biologist can ordinarily know. The uncertain reproducibility and validity of biological sampling spurred the development of formal sampling theory.A formal sampling theory developed only after change in the general intellectual attitude toward randomness, which was reflected in nineteenth-century statistics.61 The ninteenth-century attitude that randomness is not part of nature changed in the twentieth century to a view of randomness as a property of nature.62 The physicist's incorporation of randomness into physical models in response to this intellectual change late in the nineteenth-century is discussed by Bork.63 In biology, the change was initiated by the attention Darwin focused on morphological variation. The English biometricians — Francis Galton and W. F. R. Weldon, for example — were prominent in developing methods for the analysis of biological variation.64 Most pertinent to the development of sampling theory was Karl Pearson's use of frequency distributions as models of biological variation. In ecology, quantification was brought about by Ronald Fisher more than by anyone else; he incorporated randomness into sampling plans and built upon the methods developed earlier for analysis of individual variation. Fisher's use of random sampling allowed comparison between the sample collections and the collections expected from a model population of known patterning (calculated with a frequency distribution). This is a much more efficient method of determining the validity of a sample than Hensen's comparison of collections with a model uniform collection. Intellectual background and accumulated biological information caused Fisher to find variability where Hensen had seen uniformity.In summary, Victor Hensen became interested in fisheries research because of the economic importance of fishing to Germany. Hensen had considerable understanding of the prerequisites for valid sampling, but the value of his quantitative approach was limited by the general preconceptions shared by most nineteenth-century biologists. Through Hensen's efforts many other biologists were stimulated to undertake quantitative samples, even though the statistical methods for analyzing variation among populations developed only after methods for analyzing variation among individuals had been developed. *** DIRECT SUPPORT *** A8402011 00003.

Height preferences reflecting positive assortative mating for height—wherein an individual’s own height positively predicts the preferred height of their mate—have been observed in several distinct human populations and are thought to increase reproductive fitness. However, the extent to which assortative preferences for height differ strategically for short-term versus long-term relationship partners, as they do for numerous other indices of mate quality, remains unclear. We explore this possibility in a large representative sample of over 500 men and women aged 15–77 (...) from Canada, Cuba, Norway and the United States. Participants’ own heights were measured, and they indicated their height preferences for a long-term and short-term mate using graphic stimuli containing metric indices. Replicating the “male-taller norm,” participants on average preferred taller-than-average male mates, and shorter-than-average female mates. Positive assortative preferences for height were observed across sexes and samples, however the strength of these height preferences varied with relationship context for men, and not for women. Taller men preferred relatively shorter women for short-term relationships than for long-term relationships, indicating stronger assortative preferences for height in a long-term context. These results provide preliminary evidence that, in addition to mate preferences for other physical traits related to mate quality such as masculinity in the body, face, and voice, assortative preferences for height do vary as a function of expected relationship length, but this was surprisingly only observed in preferences for female height.

Previous research into film preferences and functions has looked above all at teenagers and younger to middle-aged adults. There is a lack of information in this area with respect to the behavior and preferences of older adults. In this study, for the first time, the fifty-and-older cohort was questioned in a representative sample about their film preferences. The analysis shows that the film preferences of the majority of those questioned were formed before the age of thirty. These early preferences (...) remain relatively stable. Older people generally prefer films set in a time period or dealing with historic events that they themselves experienced and with which they therefore have a certain expertise. With increasing age, older men prefer film genres that otherwise tend to be preferred by female viewers. Women, as they are older, tend to increasingly prefer female film content. (shrink)

Several studies have shown that our visual system may construct a “summary statistical representation” over groups of visual objects. Although there is a general understanding that human observers can accurately represent sets of a variety of features, many questions on how summary statistics, such as an average, are computed remain unanswered. This study investigated sampling properties of visual information used by human observers to extract two types of summary statistics of item sets, average and variance. We presented three models of (...) ideal observers to extract the summary statistics: a global sampling model without sampling noise, global sampling model with sampling noise, and limited sampling model. We compared the performance of an ideal observer of each model with that of human observers using statistical efficiency analysis. Results suggest that summary statistics of items in a set may be computed without representing individual items, which makes it possible to discard the limited sampling account. Moreover, the extraction of summary statistics may not necessarily require the representation of individual objects with focused attention when the sets of items are larger than 4. (shrink)

In a series of recent papers, Randall and Foulis report the development of a generalized theory of probability which is based on the concept of a physical operation. A central concept in this theory is that of a generalized sample space. In this paper, we introduce a generalized sample space, which for historial reasons we shall call the Poincaré sphere sample space. We investigate the relationship between this nonclassical sample space and its classical analogs, and find that the key to (...) this relationship is found in the use of idealized (Gedanken) experiments. The Poincaré sphere sample space is seen to describe a “photon” description of polarization, and the classical analogs represent different classical descriptions. We also discuss superposition and entropy for the Poincaré sphere sample space and its classical analogs, and we comment on the application of this generalized theory of probability to problems in the foundations of quantum theory.

It is unclear whether the regulatory distinction between non-identifiable and identifiable information—information used to determine informed consent practices for the use of clinically derived samples for genetic research—is meaningful to patients. The objective of this study was to examine patients' attitudes and preferences regarding use of anonymous and identifiable clinical samples for genetic research. Telephone interviews were conducted with 1,193 patients recruited from general medicine, thoracic surgery, or medical oncology clinics at five United States academic medical centers. Wanting (...) to know about research being done was important to 72% of patients when samples would be anonymous and to 81% of patients when samples would be identifiable. Only 17% wanted to know about the identifiable scenario but not the anonymous scenario. Curiosity-based reasons were the most common among patients who wanted to know about anonymous samples. Of patients wanting to know about either scenario, approximately 57% would require researchers to seek permission, whereas 43% would be satisfied with notification only. Patients were more likely to support permission in the anonymous scenario if they had more education, were Black, less religious, in better health, more private, and less trusting of researchers. The sample, although not representative of the general population, does represent patients at academic medical centers whose clinical samples may be used for genetic research. Few patients expressed preferences consistent with the regulatory distinction between non-identifiable and identifiable information. Data from this study should cause policy-makers to question whether this distinction is useful in relation to research with previously collected clinically derived samples. (shrink)

Pharmaceutical sales representatives (PSRs) are one of the most frequently used drug information sources for physicians in both the United States and China. During face-to-face interactions, PSRs use various promotional strategies to impact the prescribing behavior. In the United States, PSRs provide physicians small gifts, free drug samples, and “sincere friendships”, whereas in China, they played an indispensable role in medical corruption over the past three decades. To cope with the undue influence of PSRs, both these countries have taken (...) positive but insufficient measures to eliminate the effect thus far. By comparing the strategies of American and Chinese PSRs, it was found that building a friendly personal relationship with physicians in a relatively closed private environment (such as physician’s office) is a key factor to exert an individualized influence on physicians, even in different social backgrounds and healthcare contexts. Therefore, this essay suggests that it is necessary to limit the establishment of personal relationships and maintain a more professional interaction to reduce the personalized psychological and emotional influences on physicians’ professional judgment. To achieve this goal, it is proposed to transfer the physician-PSR interaction to a professional public space as a supplement to current countermeasures and suggestions. The presence of others and the possibility of third party participation will stimulate more ethical and reputational concerns. It is hoped that the increased transparency of the interaction will promote participants to consider more professional norms and mitigate the undue influence of PSRs’ individualized strategies.

Vast research has sought to better understand the origins and development of rape myth beliefs given the problematic influence of such misconceptions throughout global societies and criminal justice pathways. The current research aims to build on this body of literature by examining the contribution that psychopathic personality traits (affective responsiveness, cognitive responsiveness, interpersonal manipulation, egocentricity) and emotional intelligence may have upon rape myth beliefs. Furthermore, this study will investigate the extent to which sociodemographic characteristics (age, gender, ethnicity, education), and prior (...) experience of sexual victimisation, contribute to variance in rape myth acceptance scores. In total 251 participants (M Age = 31.66) completed an online, self-report questionnaire which included contemporary measures of psychopathy and rape myth acceptance, never previously tested in combination. Results of a hierarchical multiple regression analysis indicate that egocentricity, age, and gender were significantly associated with rape myth beliefs. Emotional intelligence, as well as affective and interpersonal traits of psychopathy, were not directly related with rape mythology. Findings are interpreted alongside previous research, where we suggest there is an urgent need for larger, nationally representative samples, systematically recruited from the general population to help clarify uncertainty in existing literature emerging from small-scale opportunistic datasets.

Facebook research has proliferated during recent years. However, since November 2017, Facebook has introduced a new limitation on the maximum amount of page posts retrievable through their Graph application programming interface, while there is limited documentation on how these posts are selected. This paper compares two datasets of the same Facebook page, a full dataset obtained before the introduction of the limitation and a partial dataset obtained after, and employs bootstrapping technique to assess the bias caused by the new limitation. (...) This paper demonstrates that posts with high user engagement, Photo posts and Video posts, are over-represented, while Link posts are under-represented. Top-term analysis reveals that there are significant differences in the most prominent terms between the full and partial dataset. This paper also reverse engineered the new application programming interface’s ranking algorithm to identify the features of a post that would affect its odds of being selected. Sentiment analysis reveals that there are significant differences in the sentiment word usage between the selected and non-selected posts. This paper has significant implications for the representativeness of research that use Facebook page data collected after the introduction of the limitation. (shrink)

Nonbelievers represent an understudied population in Greece. This investigation reports on the translation, cultural adaptation, and initial validation of the Nonreligious-Nonspiritual Scale, a measure designed to assess nonbelief. Data from 1754 participants were collected to examine the psychometric properties of the Greek version of the instrument and to assess the nationwide interpretability of the measure. Factor analyses suggested that the 16-item scale retained its bifactor model. Convergent validity was supported through associations with additional measures, namely, the Meaning in Life Questionnaire (...) and the Connor–Davidson Resilience Scale, which were used as reference criteria. Potential utility of the measure and future directions for ongoing development are discussed. (shrink)

Surveys are used extensively in social research and, despite a lack of conclusive evidence of their ‘representativeness,’ probability internet panel surveys are being increasingly used to make inferences about knowledge, attitude and behavior in the general population regarding a range of socially relevant issues. A large-scale survey of Australian public attitudes and behavior toward the red meat industry was undertaken. Samples were obtained using a random digit dialing telephone survey and a PIP survey to examine differences between the two (...) samples regarding attitudes and behavior relating to livestock use and welfare. There was little difference in demographics between the CATI and the PANEL surveys apart from highest level of education. However, there were differences between the two samples in both attitudes and behavior toward the red meat industry after controlling for education levels. The PANEL respondents gave generally more conservative responses than did the CATI respondents in the sense that they were more positive toward the livestock industries and animal welfare within these industries. Differences were also found between the respondents of the two samples regarding behavior that relates to the red meat industry, both community and consumer behavior. PANEL respondents were less engaged in community behaviors performed in opposition of the red meat industry when compared with the CATI sample. The majority of CATI and PANEL respondents were red meat eaters and there was no difference between respondents of the two samples in relation to red meat consumption, however, there were fewer vegetarians and vegans in the PANEL survey. Possible reasons for the observed differences are discussed, however, a definitive answer will depend on further research to identify the specific psychological factors that differ between samples derived from different survey methodologies.

Objective: Individually, vision and hearing impairments have been linked to higher levels of anxiety and depression. We investigated the effect of dual sensory impairment in a large representative sample of Spanish adults. Methods: Data from a total of 23,089 adults from the Spanish National Health Survey 2017 were analyzed. Self-reported difficulty of seeing and hearing, and depression and chronic anxiety were analyzed. Multivariable logistic regression was assessed for difficulty with vision alone, hearing alone and with difficulty with both, adjusting (...) for gender, age, marital status, living as a couple, education, smoking, alcohol consumption, BMI, physical activity, use of glasses/contact lenses, and hearing aid. Results: Visual difficulty, hearing difficulty, and dual difficulties were all associated with significantly higher odds for depression and for chronic anxiety. Dual sensory difficulty was associated with higher odds ratios for depression and anxiety when compared to either impairment alone. Conclusion: Dual sensory difficulty is associated with significantly higher odds of anxiety and depression when compared to either vision or hearing difficulty alone. Appropriate interventions are needed to address any reversible causes of vision and hearing as well as anxiety and depression in people in these specific groups. (shrink)

Remote work became the new normal during COVID-19 as a response to restrictions imposed by governments across the globe. Therefore, remote work’s impact on employee outcomes, well-being, and psychological health has become a serious concern. However, the knowledge about the mechanisms and outcomes of remote work is still limited. In this study, we expect remote work to be negatively related to bullying and assume that bullying will mediate remote work’s impact on work engagement and loneliness. To test our hypothetical model, (...) we applied a cross-sectional design using data from a large representative sample of 1,511 Norwegian workers. The data were collected in September 2021 during a period of COVID-19 restrictions in Norway. The results confirmed our hypotheses: remote work was positively related to loneliness and work engagement but negatively related to bullying. Further, bullying was positively related to loneliness and negatively related to work engagement. Moreover, bullying was also found to play a partial mediating role, supporting our hypothesis. This study suggests that remote work is related to both positive and negative mechanisms in the workplace. Remote work can potentially reduce bullying and have a protective function in preventing bullying. However, since remote work has positive relations with both loneliness and work engagement, this study illustrates that organizations should be cautious and perhaps consider a moderate level of remote work. Hence, the results have several implications for HR policies and management. (shrink)

The small sample properties of estimators and tests are frequently too complex to be useful or are unknown. Much econometric theory is therefore developed for very large or asymptotic samples where it is assumed that the behaviour of estimators and tests will adequately represent their properties in small samples. Refined asymptotic methods adopt an intermediate position by providing improved approximations to small sample behaviour using asymptotic expansions. Dedicated to the memory of Michael Magdalinos, whose work is a major (...) contribution to this area, this book contains chapters directly concerned with refined asymptotic methods. In addition, there are chapters focusing on new asymptotic results; the exploration through simulation of the small sample behaviour of estimators and tests in panel data models; and improvements in methodology. With contributions from leading econometricians, this collection will be essential reading for researchers and graduate students concerned with the use of asymptotic methods in econometric analysis.
