The Human Affectome
Over the last decades, the interdisciplinary field of the affective sciences has seen proliferation rather than integration of theoretical perspectives. This is due to differences in metaphysical and mechanistic assumptions about human affective phenomena (what they are and how they work) which, shaped by academic motivations and values, have determined the affective constructs and operationalizations. An assumption on the purpose of affective phenomena can be used as a teleological principle to guide the construction of a common set of metaphysical and mechanistic assumptions—a framework for human affective research. In this capstone paper for the special issue “Towards an Integrated Understanding of the Human Affectome”, we gather the tiered purpose of human affective phenomena to synthesize assumptions that account for human affective phenomena collectively. This teleologically-grounded framework offers a principled agenda and launchpad for both organizing existing perspectives and generating new ones. Ultimately, we hope Human Affectome brings us a step closer to not only an integrated understanding of human affective phenomena, but an integrated field for affective research
Thermomechanical characterization of on-chip buckled dome Fabry-Perot microcavities
We report on the thermomechanical and thermal tuning properties of
curved-mirror Fabry-Perot resonators, fabricated by the guided assembly of
circular delamination buckles within a multilayer a-Si/SiO2 stack. Analytical
models for temperature dependence, effective spring constants, and mechanical
mode frequencies are described and shown to be in good agreement with
experimental results. The cavities exhibit mode volumes as small as
, reflectance-limited finesse , and
mechanical resonance frequencies in the MHz range. Monolithic cavity arrays of
this type might be of interest for applications in sensing, cavity quantum
electrodynamics, and optomechanics.Comment: \c{opyright} 2015 Optical Society of America. One print or electronic

Testosterone, cortisol, and serotonin as key regulators of social aggression: A review and theoretical perspective
In human and non-human animals the steroid hormones cortisol and testosterone are involved in social aggression and recent studies suggest that these steroids might jointly regulate this behavior. It has been hypothesized that the imbalance between cortisol and testosterone levels is predictive for aggressive psychopathology, with high testosterone to cortisol ratio predisposing to a socially aggressive behavioral style. In this review, we focus on the effects of cortisol and testosterone on human social aggression, as well as on how they might modulate the aggression circuitry of the human brain. Recently, serotonin is hypothesized to differentiate between impulsive and instrumental aggression, and we will briefly review evidence on this hypothesis. The aim of this article is to provide a theoretical framework for the role of steroids and serotonin in impulsive social aggression in humans
The Development and Validation of the Empathy Components Questionnaire (ECQ)
Key research suggests that empathy is a multidimensional construct comprising of both cognitive and affective components. More recent theories and research suggest even further factors within these components of empathy, including the ability to empathize with others versus the drive towards empathizing with others. While numerous self-report measures have been developed to examine empathy, none of them currently index all of these wider components together. The aim of the present research was to develop and validate the Empathy Components Questionnaire (ECQ) to measure cognitive and affective components, as well as ability and drive components within each. Study one utilized items measuring cognitive and affective empathy taken from various established questionnaires to create an initial version of the ECQ. Principal component analysis (PCA) was used to examine the underlying components of empathy within the ECQ in a sample of 101 typical adults. Results revealed a five-component model consisting of cognitive ability, cognitive drive, affective ability, affective drive, and a fifth factor assessing affective reactivity. This five-component structure was then validated and confirmed using confirmatory factor analysis (CFA) in an independent sample of 211 typical adults. Results also showed that females scored higher than males overall on the ECQ, and on specific components, which is consistent with previous findings of a female advantage on self-reported empathy. Findings also showed certain components predicted scores on an independent measure of social behavior, which provided good convergent validity of the ECQ. Together, these findings validate the newly developed ECQ as a multidimensional measure of empathy more in-line with current theories of empathy. The ECQ provides a useful new tool for quick and easy measurement of empathy and its components for research with both healthy and clinical populations
Bootcamp - Longitudinaler „Skills-Kurs“ zur Vermittlung klinischer und operativer Fertigkeiten : Unter Berücksichtigung geschlechtsspezifischer Unterschiede
BACKGROUND: Sex parity of medical students has increased to the degree that approximately 50 % of medical students are women. Orthopedic and trauma surgery, however, has not managed to keep up with this trend and women are still grossly underrepresented.
OBJECTIVES: Description of an innovative longitudinal gender-based surgical and clinical skills training course.
METHODS: An elective 5-day modular skills course is offered for third to fifth year medical students. Module 1 aims at teaching basic surgical and communication skills involving local and regional anesthesia, initial experience with arthroscopy, fracture fixation, emergency measures as well as communication skills training using standardized patients. The subsequent modules cover surgical knowledge and skills of increasing complexity. The main goals are to increase the interest in orthopedic trauma surgery and to reduce concerns regarding discrimination and gender-related issues. Learning outcomes are assessed using a 6-item multiple choice questionnaire (MCQ) and a 3-stage objective structured clinical examination (OSCE) regarding induction of anesthesia, arthroscopy simulation and communication skills.
RESULTS: A total of 52 second year medical students (39 females, 13 males) completed module I. There were no differences between men and women with regard to the MCQ and anesthesia and communication skills; however, male students scored significantly higher in the arthroscopy test. All students rated the course as being highly effective in terms of acquisition of knowledge and skills. Almost all participants would recommend the course to fellow students and 70 % of participants stated they would participate in the advanced courses. Female participants in particular reported a marked increase in interest in orthopedic trauma surgery and less concerns regarding discrimination and gender-related issues.
CONCLUSION: The effectiveness of the approach will have to be proven by further evaluation, especially with respect to assessment of career development and application rates of participants. Adaptation of environmental and working conditions to suit women's needs seem to play an important role in promoting new surgery residents
The impact of social exclusion vs. inclusion on subjective and hormonal reactions in females and males
ILDE: community environment for conceptualizing, authoring and deploying learning activities
Comunicació presentada a: 9th Open Learning and Teaching in Educational Communities, EC-TEL 2014, celebrada del 16 al 19 de setembre de 2014 a Graz, Austria.This demonstration paper presents the Integrated Learning Design Environment (ILDE). ILDE is being developed in the METIS project, which aims at promoting the adoption of learning design by providing integrated support to teachers throughout the whole design and implementation process (or lifecycle). ILDE integrates existing free- and open-source tools that include: codesign support for teacher communities; learning design editors following different authoring and pedagogical approaches; interface for deployment of designs on mainstream Virtual Learning Environments (VLEs). The integration is designed so that teachers experience a continuous flow while completing the tasks involved in the learning design lifecycle, even when the tasks are supported by different tools. ILDE uses the LdShake platform to provide social networking features and to manage the integrated access to designs and tooling including conceptualization tools (OULDI templates), editors (WebCollage, OpenGLM), and deployment into VLEs (e.g., Moodle) via GLUE!-PS.This work has been partially funded by EACEA, METIS Project 531262-LLP-2012-ES-KA3-KA3MP and the Spanish EEE project (TIN2011-28308-C03-03).

Social Cognition, the Male Brain and the Autism Spectrum
Behavioral studies have shown that, at a population level, women perform better on tests of social cognition and empathy than men. Furthermore Autism Spectrum Disorders (ASDs), which are characterized by impairments in social functioning and empathy, occur more commonly in males than females. These findings have led to the hypothesis that differences in the functioning of the social brain between males and females contribute to the greater vulnerability of males to ASD and the suggestion that ASD may represent an extreme form of the male brain. Here we sought to investigate this hypothesis by determining: (i) whether males and females differ in social brain function, and (ii) whether any sex differences in social brain function are exaggerated in individuals with ASD. Using fMRI we show that males and females differ markedly in social brain function when making social decisions from faces (compared to simple sex judgements) especially when making decisions of an affective nature, with the greatest sex differences in social brain activation being in the inferior frontal cortex (IFC). We also demonstrate that this difference is exaggerated in individuals with ASD, who show an extreme male pattern of IFC function. These results show that males and females differ significantly in social brain function and support the view that sex differences in the social brain contribute to the greater vulnerability of males to ASDs.Publisher PDFPeer reviewe
