On the Neuronal Dynamics of Aesthetic Experience: Evidence from Electroencephalographic Oscillatory Dynamics.

Aesthetic experiences have an influence on many aspects of life. Interest in the neural basis of aesthetic experiences has grown rapidly in the past decade, and fMRI studies have identified several brain systems supporting aesthetic experiences. Work on the rapid neuronal dynamics of aesthetic experience, however, is relatively scarce. This study adds to this field by investigating the experience of being aesthetically moved by means of ERP and time-frequency analysis. Participants' EEG was recorded while they viewed a diverse set of artworks and evaluated the extent to which these artworks moved them. Results show that being aesthetically moved is associated with a sustained increase in gamma activity over centroparietal regions. In addition, alpha power over right frontocentral regions was reduced in high- and low-moving images, compared to artworks given intermediate ratings. We interpret the gamma effect as an indication for sustained savoring processes for aesthetically moving artworks compared to aesthetically less-moving artworks. The alpha effect is interpreted as an indication of increased attention for aesthetically salient images. In contrast to previous works, we observed no significant effects in any of the established ERP components, but we did observe effects at latencies longer than 1 sec. We conclude that EEG time-frequency analysis provides useful information on the neuronal dynamics of aesthetic experience.

Assessing measurement invariance in the EORTC QLQ-C30.

PURPOSE: We aimed to investigate measurement invariance (MI) in the European Organisation for research and treatment of cancer quality of life questionnaire core 30 (EORTC QLQ-C30) in a heterogeneous sample of patients with cancer. METHODS: Data from 12 studies within the PROFILES registry were used for secondary analyses (n = 7007). We tested MI by successive restrictions on thresholds, loadings, and intercepts across subgroups based on primary cancer sites, age, sex, time since diagnosis, and life stage, using multigroup confirmatory factor analysis (MGCFA) for ordered categorical measures. We also evaluated the impact of potentially miss-specified parameter equality across groups on latent factor means by releasing threshold and loading equality constraints for each item at a time. RESULTS: Results showed that the highest level of MI (invariance of thresholds, loadings, and intercepts) was found across groups based on time since diagnosis and life stage and to a lesser extent across groups based on sex, age, and primary tumor site. On item level, however, changes in the item's associated factor means were relatively small and in most cases canceled each other out to some extent. CONCLUSIONS: Given only a few instances of non-invariance in our study, there is reason to be confident that valid conclusions can be drawn from between-group comparisons of QLQ-C30 latent means as operationalized in our study. Nonetheless, further research into MI between other subgroups for the QLQ-C30 (i.e., treatment effects and ethnicity) is warranted. We stress the importance of including MI evaluations in the development and validation of measurement instruments.

A combined epicardial implantation and subsequent extraction strategy in pacemaker device infection in pacemaker-dependent patients.

INTRODUCTION: Treatment infections is challenging in pacemaker (PM) dependent patients. We proposed a novel implantation strategy for this group of patients. METHODS: Patients who were PM dependent and were admitted with a PM infection received a combined procedure of left ventricular (LV) epicardial implantation of a PM lead and subsequent extraction of the infected system. No temporary pacing wire was used and the PM generator was placed in the left flank. RESULTS: Between 2012 and 2015 we treated 16 patients who were PM dependent and with a PM infection. The majority of patients were male (81% [13/16]) and the median age was 71 years (50-91). The cause of infection was valvular endocarditis in 38% (6/16), lead infection in 25% (4/16), and isolated pocket infection in 38% (6/16). All patients underwent epicardial implantation of a LV lead (1084T bipolar lead; St. Jude Medical Myodex, St. Paul, MN, USA) and extraction of the infected device. There was no occurrence of periprocedural mortality and no postprocedural tamponades. There was one complication in the form of a hemorrhage at the infected device extraction site. In the median follow-up period of 17 months there were four of 16 deaths, none of which were attributable to epicardial LV implantation. LV-lead threshold was 1.1V (±0.7V) upon implantation that increased to 1.2V (±0.6V) at 0.4-ms pulse duration. There were no reinfections of the epicardial lead or device. CONCLUSION: Epicardial left ventricle PM implantation and subsequent extraction of an infected PM in PM-dependent patients is feasible and safe with good long-term outcome.

The preferred role and perceived performance of the welfare state: European welfare attitudes from a multidimensional perspective.

Welfare state support has two core dimensions: attitudes about what the welfare state should do and beliefs about its actual performance. People can combine any position on one dimension with any position on the other, yielding four opinion clusters: people can combine preferences for a relatively strong role of the welfare state with a perception of a relatively low or high welfare state performance; likewise, people preferring a small role of the welfare state can perceive a high or low performing welfare state. We apply Latent Class Factor Analysis to data of 22 European countries from the 2008/9 European Social Survey. We find that each of the four clusters contains a substantial proportion of respondents that differs between welfare regimes. In addition, cluster membership is also related to covariates that measure people's structural positions and ideological preferences.

Bayes factor testing of equality and order constraints on measures of association in social research.

Measures of association play a central role in the social sciences to quantify the strength of a linear relationship between the variables of interest. In many applications researchers can translate scientific expectations to hypotheses with equality and/or order constraints on these measures of association. In this paper a Bayes factor test is proposed for testing multiple hypotheses with constraints on the measures of association between ordinal and/or continuous variables, possibly after correcting for certain covariates. This test can be used to obtain a direct answer to the research question how much evidence there is in the data for a social science theory relative to competing theories. The stand-alone software package 'BCT' allows users to apply the methodology in an easy manner. The methodology will also be available in the R package 'BFpack'. An empirical application from leisure studies about the associations between life, leisure and relationship satisfaction and an application about the differences about egalitarian justice beliefs across countries are used to illustrate the methodology.

Quality of life and quality of care as experienced by patients with advanced cancer and their relatives: A multicentre observational cohort study (eQuiPe).

AIM: This study aims to assess the quality of life and quality of care as experienced by patients with advanced cancer and their relatives while taking their interdependency into account. METHODS: A prospective multicentre observational study (eQuiPe study) was conducted. Quality of life scores (EORTC QLQ-C30) was compared to a matched normative population and logistic regression analyses were conducted to assess the relation between high emotional functioning (EF, measured with the EORTC QLQ-C30) and experienced quality of care (IN-PATSAT32, CQ-index PC). RESULTS: In total, 1103 (65%) patients and 831 (71%) relatives completed the baseline questionnaire, including 699 unique patient-relative couples. Patients experienced lower EF than the normative population (78 versus 87, p < .001). Compared to patients, relatives reported clinically relevantly lower EF (69 versus 78, p < .001). Being more satisfied with care in general (p < .05) and clarity about the key health-care provider (p < .05) was positively associated with high EF in patients. For relatives, experienced continuity of care (p < .01) and information for the patient (p < .05) were positively associated with high EF. The EF of patients (p < .001) and relatives (p < .001) were positively associated with each other and continuity of care as perceived by relatives was positively associated with high EF in patients (p < .01). CONCLUSIONS: Patients with advanced cancer reported low levels of EF but their relatives reported even lower levels of EF. Experienced integrated organisation and satisfaction with care were positively related to EF. The interdependent relation between patients' and relatives' EF and their care experiences suggests that a family-centred approach can optimise palliative cancer care. TRIAL REGISTRATION: The eQuiPe study is registered as NTR6584 in the Netherlands Trial Register.

From Experience to Memory: On the Robustness of the Peak-and-End-Rule for Complex, Heterogeneous Experiences.

Memory forms the input for future behavior. Therefore, how individuals remember a certain experience may be just as important as the experience itself. The peak-and-end-rule (PE-rule) postulates that remembered experiences are best predicted by the peak emotional valence and the emotional valence at the end of an experience in the here and now. The PE-rule, however, has mostly been assessed in experimental paradigms that induce relatively simple, one-dimensional experiences (e.g., experienced pain in a clinical setting). This hampers generalizations of the PE-rule to the experiences in everyday life. This paper evaluates the generalizability of the PE-rule to more complex and heterogeneous experiences by examining the PE-rule in a virtual reality (VR) experience, as VR combines improved ecological validity with rigorous experimental control. Findings indicate that for more complex and heterogeneous experiences, peak and end emotional valence are inferior to other measures (such as averaged valence and arousal ratings over the entire experiential episode) in predicting remembered experience. These findings suggest that the PE-rule cannot be generalized to ecologically more valid experiential episodes.

Partnership in health care: views of family caregivers on sharing care responsibility with government, clients and health insurers.

In this study, we asked family caregivers about their opinion on division of care responsibility between the government, family caregivers, clients, and health insurers. We investigated whether different clusters of respondents could be distinguished, using Latent Cluster Analysis, and what is the relation is with perceived stress and joy and with several background characteristics. Three clusters of respondents could be distinguished: a 'caring together', a 'caring individually', and a 'government-responsible caring' cluster. Family caregivers in cluster 1 attach great importance to both governmental responsibility and individual responsibility. Family caregivers who belong to cluster 2 want themselves to take full responsibility for caregiving, and caregivers in cluster 3 want the government to take most of the responsibility for caregiving. Unemployed caregivers and caregivers with lower educational attainment have a higher chance to belong to the 'caring individually' cluster and this group has relatively more self-reported stress. Policymakers and professionals should bear these three clusters in mind when developing care policy and care guiding practice.

Clusters of cultures: diversity in meaning of family value and gender role items across Europe.

Survey data are often used to map cultural diversity by aggregating scores of attitude and value items across countries. However, this procedure only makes sense if the same concept is measured in all countries. In this study we argue that when (co)variances among sets of items are similar across countries, these countries share a common way of assigning meaning to the items. Clusters of cultures can then be observed by doing a cluster analysis on the (co)variance matrices of sets of related items. This study focuses on family values and gender role attitudes. We find four clusters of cultures that assign a distinct meaning to these items, especially in the case of gender roles. Some of these differences reflect response style behavior in the form of acquiescence. Adjusting for this style effect impacts on country comparisons hence demonstrating the usefulness of investigating the patterns of meaning given to sets of items prior to aggregating scores into cultural characteristics.

The Multidimensionality of Welfare State Attitudes: A European Cross-National Study.

When evaluating the various aspects of the welfare state, people assess some aspects more positively than others. Following a multidimensional approach, this study systematically argues for a framework composed of seven dimensions of the welfare state, which are subject to the opinions of the public. Using confirmatory factor analyses, this conceptual framework of multidimensional welfare attitudes was tested on cross-national data from 22 countries participating in the 2008 European Social Survey. According to our empirical analysis, attitudes towards the welfare state are multidimensional; in general, people are very positive about the welfare state's goals and range, while simultaneously being critical of its efficiency, effectiveness and policy outcomes. We found that these dimensions relate to each other differently in different countries. Eastern/Southern Europeans combine a positive attitude towards the goals and role of government with a more critical attitude towards the welfare state's efficiency and policy outcomes. In contrast, Western/Northern Europeans' attitudes towards the various welfare state dimensions are based partly on a fundamentally positive or negative stance towards the welfare state.

Ranked motives of long-term care providing family caregivers.

Family caregivers provide long-term care to their chronically ill loved ones and as a consequence they experience physical, relational and financial problems. This study investigates how long-term family caregivers rank 12 motives for caregiving. Motives are derived from the views of four philosophical anthropologists and are related to self-reported stress and joy and to several different background characteristics of respondents. Motives that focus on feelings concerning the relationship between caregiver and care recipient are more popular as a first choice than motives stemming from feelings of obligation or a general feeling of happiness and are also more popular than more self-directed motives. An analysis of full ranking data shows that two groups can be distinguished, one group of family caregivers with mixed motives and one group of family caregivers with motives that focus on reciprocal mutually equal relationships. The latter are mainly women taking care for a partner or a child, the former report high levels of stress. Implications for intervention programmes and health policy are being discussed.
