Following up on articles recently published in this journal, the present contribution tells (some of) “the rest of the story” about the value of randomization in single‐case intervention research investigations. Invoking principles of internal, statistical‐conclusion, and external validity, we begin by emphasizing the critical distinction between design randomization and analysis randomization, along with the necessary correspondence between the two. Four different types of single‐case design‐and‐analysis randomization are then discussed. The persistent negative influence of serially dependent single‐case outcome observations is highlighted, accompanied by examples of inappropriate applications of parametric and nonparametric tests that have appeared in the literature. We conclude by presenting valid applications of single‐case randomization procedures in various single‐case intervention contexts, with specific reference to a freely available Excel‐based software package that can be accessed to incorporate the present randomization schemes into a wide variety of single‐case intervention designs and analyses.  相似文献

Bicycles are an environmentally-friendly, energy-saving mode of transportation. Public bike-and-ride is a term used to describe the use of public bicycles combined with transit as a means of transportation. A new stated preference (SP) design scheme based on the factors respondents felt were most important was proposed to augment the traditional SP design under complex multi-factor and multi-level situations. iPads were used to automatically administer the survey under each design scheme and collect the choice behavior data for public bike-and-ride. The concept of perceived psychological distance was further proposed and used to estimate Logit models. Comparative analysis of these models shows for the traditional SP design scheme, some factors, including perceived psychological distance, have reduced statistically significant effects on public bike-and-ride choice relative to the new SP design scheme. This indicates that in scenarios with complex decisions, the decision-makers would reduce their consideration of some factors and simplify their decision process making the new SP survey design scheme more suitable to analyze their choice behavior in those cases. Model analysis showed that perceived psychological distance for each traveler is the most critical factor during the decision process for travel behavior analysis. Finally, sensitivity analysis was conducted to determine which factors in the new survey design were important to increase the share of public bike-and-ride users. Practical findings for promoting public bike-and-ride use are presented in addition to theoretical references for improving the traditional survey methods.  相似文献

While economic downturns have adverse effects on young people's life chances, empirical studies examining whether and to what extent human values, social attitudes and well‐being indicators respond to sudden economic shocks are scarce. To assess the claim that human values are less affected by economic shocks than social attitudes and well‐being, two distinct yet related studies based on the European Social Survey (ESS) are conducted. The first employs a fixed effects pseudo‐panel analysis of the 2008–2014 ESS‐waves to detect whether changes over time in the socio‐demographic group's unemployment risk and national youth unemployment affect individual dispositions to varying degrees. The second study captures micro‐ and cross‐national effects in the 2010 ESS cross‐section. Unique for this set‐up is that we can test whether the findings hold for over‐time changes in youth unemployment within countries (pseudo‐panel), as well as for cross‐country differences in youth unemployment (multilevel). Both studies indicate that political trust, satisfaction with the economy and subjective well‐being are lowered by economic risk and hardship, while social trust and self‐rated health are less affected by changes in youth unemployment. Secondly, human values are immune to economic risk, underscoring that values transcend specific situations and are therefore resistant against sudden economic shocks.  相似文献

The principles and techniques of design education have begun to influence art education in the United States, but their effect so far has been modest, primarily because of a gaping divide in beliefs about creativity and how to stimulate it. With K–12 art education on the chopping block of a culture awash with budget cuts and testing fever, this is a particularly a significant time to examine these disparate conceptions. The argument here is that the division that exists today between pre‐K–12 art education and design education in the United States is not justified and ignores historical perspective. After describing and comparing the two approaches, we examine how conceptions of creativity in the visual arts may have led to this artificial separation of similar disciplines. Because educators in many countries grapple with defining and implementing creative art education curricula, this article will consider international perspectives that offer insights for American art educators.  相似文献

Maternal mind-mindedness has been shown to be a powerful predictor of many developmental outcomes and to buffer the impact of psychosocial risk conditions, but no study has investigated whether this parental feature might support child development in the presence of biological risk, such as preterm birth. The present study addresses this gap, by investigating whether early maternal mind-mindedness contributes to the growth of a child’s linguistic abilities in the following two years of life, and if the contribution of this maternal feature might be stronger in the presence of preterm birth. Forty mother–child dyads (twenty with a preterm infant) were followed longitudinally, with maternal mind-mindedness assessed at 14 months of age and child’s expressive linguistic abilities at 24 and 36 months through observational measures. Multilevel models showed that linguistic abilities increased from 24 to 36 months of age, but that this increase was stronger in full-term infants. Maternal mind-mindedness also contributed to this growth, playing a stronger role in preterm infants than in full-term infants. Altogether, these findings contribute more deeply to the understanding of language development in preterm infants and of the joint contribution made by biological risk and environmental factors; from a practical standpoint, they suggest the importance of addressing mother’s mind-mindedness in order to support child’s language development.  相似文献

In this study we test the Unified Model of Aesthetics (Hekkert, 2014), which posits that the aesthetic sense has evolved to identify and value prospects for safety and accomplishment. The principles of unity-in-variety, most-advanced-yet-acceptable and autonomous-yet-connected are considered manifestations of these conflicting urges at separate levels of stimulus processing. We empirically integrate these principles to gauge their unique contribution to the aesthetic experience, using two distinct surveys (study 1–300 respondents and 20 stimuli, study 2–60 respondents and 24 stimuli). Both surveys confirm the three principles constituting the Unified Model of Aesthetics. The principles are found to operate independently and jointly, although unity-in-variety has the strongest impact on aesthetic pleasure.  相似文献

Newton claims to have proven the heterogeneity of light through his experimentum crucis. However, Olaf Müller has worked out in detail Goethe’s idea that one could likewise prove the heterogeneity of darkness by inverting Newton’s famous experiment. Müller concludes that this invalidates Newton’s claim of proof. Yet this conclusion only holds if the heterogeneity of light and the heterogeneity of darkness is logically incompatible. This paper shows that this is not the case. Instead, in Quine’s terms, we have two logically compatible theories based on mutually irreducible theoretical terms. From a Quinean point of view, this does no harm to the provability of the corresponding statements.  相似文献

The quality of working life under the production system known as lean manufacturing (LM) is a heavily debated topic. Little is known about the engagement level of employees under this system. Our study is concerned with how employees in this context craft their jobs to enhance their own engagement, and we specifically consider how daily skill utilization triggers this process. Using a cross-level perspective, we further consider whether job-level characteristics relevant to the lean context, namely task interdependence and boundary control, restrict or facilitate the effects of daily skill utilization. A daily diary study was conducted over 4 working days with 64 employees in a large company utilizing LM. The results of multilevel structural equation modelling demonstrated that on a given day, skill utilization was associated with seeking resources, and this relationship was stronger when employees had high boundary control and low task interdependence in their general job roles. Results further demonstrated that employees experienced higher work engagement on days when they sought resources and challenges. Our findings illustrate the motivational potential of job crafting under LM and how crafting activities can be facilitated by the design of jobs and allocation of daily tasks.  相似文献
