Text‐based communication is one of the substantial ways of spreading scientific information. While the content and contextual aspects of written words have been widely researched, the impact of font characteristics on text perception is an almost blank page. The following study deals with the influence of serifs on the evaluation of online‐presented scientific abstracts. Yet there is only evidence for faster reading times when texts are presented in sans‐serif fonts, although the opposite is stated in parts of the literature. The present work examines if the presence or absence of serifs also have an impact on the appraisal of scientific texts when all other important font characteristics do not change. For this purpose, 188 university students participated in an online experiment and rated different aspects of scientific abstracts as well as of the research outlined in the abstracts. The results show that missing serifs led to increased reading speed. However, and in contrast to the perceptual fluency hypothesis, the presence of serifs had a positive effect on all evaluation dimensions. The results of a second study with 187 participants also indicated that reading fluency counteracted the liking of texts. Implications for future studies and media production are discussed.  相似文献

Using an empirical data set, we investigated variation in factor model parameters across a continuous moderator variable and demonstrated three modeling approaches: multiple-group mean and covariance structure (MGMCS) analyses, local structural equation modeling (LSEM), and moderated factor analysis (MFA). We focused on how to study variation in factor model parameters as a function of continuous variables such as age, socioeconomic status, ability levels, acculturation, and so forth. Specifically, we formalized the LSEM approach in detail as compared with previous work and investigated its statistical properties with an analytical derivation and a simulation study. We also provide code for the easy implementation of LSEM. The illustration of methods was based on cross-sectional cognitive ability data from individuals ranging in age from 4 to 23 years. Variations in factor loadings across age were examined with regard to the age differentiation hypothesis. LSEM and MFA converged with respect to the conclusions. When there was a broad age range within groups and varying relations between the indicator variables and the common factor across age, MGMCS produced distorted parameter estimates. We discuss the pros of LSEM compared with MFA and recommend using the two tools as complementary approaches for investigating moderation in factor model parameters.  相似文献

Hepatocellular carcinoma (HCC) represents the third leading cause of cancer-related death. Because HCC is multicentric with time, excluding the few transplanted patients, sooner or later it becomes untreatable with loco-regional therapies and, until some years ago, it was not responsive to systemic therapies. In 2005 a randomized trial indicated the efficacy of a product containing stem cell differentiation stage factors (SCDSF) taken from zebrafish embryos during the stage in which the totipotent stem cells are differentiating into the pluripotent adult stem cells. In such a trial the patients, with “intermediate” and “advanced” HCC according to Barcelona Clinic Liver Cancer/American Association for the Study of Liver Diseases (BCLC/AASLD) guidelines, presented benefit in terms of performance status and objective tumoral response, with some cases (2.4%) of complete response, that is, sustained disappearance of the neoplastic areas or blood supply therein, accompanied by normalization of alpha-fetoprotein (AFP) levels (complete response [CR]). A second study reporting the experience of a tertiary referral center on patients with “advanced” stage confirmed the possibility to obtain CR. Out of 38 patients, 5 presented a sustained CR (13.1%). Improvement on PS was obtained in 17 patients (34.6%). No side effects occurred.  相似文献

In social and organizational research, theory is conventionally used to explain social phenomena. However, theory may be transformative in the sense that in using and testing the theory in a practical domain, researchers may attempt to help practitioners transform and improve their social practices and institutions. This idea is illustrated by a research-and-development project in Denmark, headed by the author, which used transformative theory to design professional conferences that are more conducive to participant learning and involvement than is the conventional, lecture-based format. A number of learning techniques were derived from the theory and were tested as hypotheses: When implemented in thirty live conference experiments, did they contribute to learning, as specified by the theory? Used in this manner, transformative theory may supplement the aspirations motivating change agents by some of the well-known qualities of scientific research, including theoretical grounding, a coherent ontology, testable hypotheses, systematic evaluation, external validity, and theory–action consistency.  相似文献

In one of its most urgent folds, Catherine Keller's Cloud of the Impossible juxtaposes negative theology with relational theology for the sake of thinking constructively about today's global climate of religious conflict and ecological upheaval. The tension between these two theological approaches reflects her desire to unsay past harmful theological speech but also to speak into the present silences about the (perhaps im)possibility of a future that is not only to be feared. Suffusing Keller's Cloud is the related (perhaps im)possibility of living out one's life in conversation with a religious tradition having accepted the nonknowing character of its wisdom. Here, I develop the notion of “hypothetical faith” as an epistemic posture that commits itself to some particular religious tradition even as it acknowledges the unverifiability of that tradition's deepest truths. Understood as operating at the opposite end of the testability spectrum from science, religion‐as‐hypothesis provides a way of saying and unsaying one's tradition at the same time.  相似文献

Background and Objectives: Describing emotional experiences using distinct terms, or affect differentiation, has been associated with emotion regulation and adaptive behavior under stress. There is little data, however, examining the association between differentiation and dispositional factors underlying psychopathology. The current study examines the association between differentiation and trait anxiety (TA) given prior evidence of cognitive biases in TA relevant to higher order processing of emotional experiences.

Design: We examined cross-sectionally, via lab-based repeated assessment, the association between differentiation of negative and positive experiences and TA.

Methods: Two hundred twenty-two adults completed an emotion reactivity task including repeated assessments of affect. We hypothesized that individuals higher in trait anxiety (HTA) would have greater difficulty differentiating their experiences.

Results: HTA individuals exhibited lower levels of negative affect (NA) differentiation even when controlling for depression. Although negative emotion intensity was consistently associated with lower differentiation, this did not account for the influence of HTA on differentiation.

Conclusions: These data suggest that HTA individuals have greater difficulty differentiating negative emotions, regardless of negative emotion intensity and depression. As HTA is common to many emotional disorders; this evidence suggests that poor differentiation may also be an important transdiagnostic consideration in models of risk and of affective disease.  相似文献

The goal of this project has been to explore the characteristics of the self as a complex adaptive system. It began with the effort to provide a foundation for a developmental theory based on principles from self psychology that also permitted the incorporation of some of the recent findings from neuroscience. Part I (Palombo, 2013a Palombo, J. (2013a). The self as a complex adaptive system part I: Complexity, metapsychology, and developmental theories. Psychoanalytic Social Work, 20(1), 125.[Taylor &; Francis Online] [Google Scholar]) outlined some features of nonlinear dynamic systems theory and complexity science that provided the basis for a critique of traditional psychodynamic developmental theories. This critique was followed in Part II (Palombo, 2013b Palombo, J. (2013b). The self as a complex adaptive system part II: Levels of analysis and the position of the observer. Psychoanalytic Social Work, 20(2), 119.[Taylor &; Francis Online] [Google Scholar]) with the proposal of a levels-of-analysis perspective as a methodology to organize the data on development, the three levels of analysis being the neuropsychological, the introspective, and the interpersonal. This article, Part III, outlines the trends that contributed to the revised view of development and proposes a set of processes that are consistent with a nonlinear dynamic perspective that govern human beings' mental activities during development. These processes are the progression from lower to higher levels of complexity, the movement from lesser to greater differentiation, and advancement from lesser to greater individuation.  相似文献

The authors tested three theoretical models linking self, stress, and psychopathological distress in emerging adulthood. The vulnerability model posits that self-concept pathology leads to distress. The scarring model postulates that distress and stress lead to self-concept pathology. The stress generation model stipulates that distress and self-concept pathology lead to the experience of episodic and chronic life stress. Change in ruminative brooding was examined as a potential mechanism in all models. One-hundred and seventy Israeli freshmen (M[age]?=?23.19, 68% females) were followed up three times over the duration of one year. Distress and six dimensions of the self (self-criticism, self-concept inadequacy, hated sense of self, self-esteem, generalized self-efficacy, and self-concept clarity) were assessed repeatedly. Acute and chronic stresses were measured at Time 2 using the University of California, Los Angeles (UCLA) Stress Interview. Distress prospectively predicted self-concept pathology pertaining to all of the dimensions, except self-concept clarity, which was adversely affected by chronic stress. Change in ruminative brooding mediated scarring for self-criticism, a hated self, and self-concept clarity. Low self-esteem emerged as a powerful chronic stress generator. Self-concept clarity was as the only dimension leading to change in distress. In emerging adulthood, psychological distress and—to a lesser extent—chronic stress might “scar” the self.  相似文献

Ninety-one dreams collected during the Covid-19 pandemic (the epidemic-situation sample) were compared with ninety-one dreams collected before the start of the epidemic (the non-epidemic-situation sample). The dreams were classified according to their content, using methods based on previous studies. The frequency of themes was compared to predictions that would be anticipated by three contemporary theories of dreaming: 1) threat simulation theory (TST); 2) incorporation continuity hypothesis (ICH); and 3) social simulation theory (SST). The epidemic-situation sample dreamed more of threatening events than the non-epidemic-situation sample (supporting the TST) and more of non-aggression threatening events, possibly due to the hyperassociation during sleep. However, the epidemic-situation sample did not show a greater prevalence of illness events in dreams (not supporting the ICH). Additionally, there was no significant difference in social neutral and positive events in dreams between the two samples as would have been predicted by the SST.  相似文献
