Full textAbstract:
The present study aiming to verify the interference of different conditions (treadmill vs. track) on critical velocity (CV) values, as well as on the correlation to the 3000-meter performance (v3000m), and thus infer about the specificity of each values as training parameter for this distance. Seven runners (15.3±1.4 years) were submitted to a maximal progressive test (1.0 km×h-1 increments per minute until exhaustion) to assess V̇O2max and maximal aerobic velocity (vV̇O2max). Subsequently, CV was estimated from three running performances at each test condition, with exercise intensities adjusted for different time limits (tLim) at 900, 2100 and 3300 meters in track or at 90, 95 and 115% of vV̇O2max in treadmill. From linear adjustments, using stepwise method, CV was assessed on treadmill (CVTREADMILL) and track (CVTRACK), and both compared by the Mann-Whitney test. The sample-adjusted dispersion coefficient (R2 adj) analyzed the varianceof v3000m with CVTRACK, CVTREADMILL and vV̇O2max. In all analyses, significance was set at P≤0.05. In progressive test, V̇O2max reached 54.2±5.2 mLO2×kg-1×min-1 and vV̇O2max reached 16.8±1.9 km×h-1. No differences were observed between CVTREADMILL and CVTRACK (14.0±1.8 vs. 12.3±3.2 km×h-1, P=0.46). Correlations were observed for v3000m with CVTREADMILL (R2 adj ~0.94), CVTRACK (R2 adj ~0.99) and vV̇O2max (R2 adj ~0.90), all showing P=0.001. It could be concluded that no influence was observe on the ability to achieve identical CV values from different assessment conditions. The correlation to the v3000 meters suggested better specificity of CVTRACK than CVTREADMILL for training prescription and performance control.

The purpose of this research is to determine the impact of the turf-only substrate and turf–perlite in the ratio 2:1 and of growth regulators in the quality of adventive roots ( the number and length) of well lignified one-year old branches without fruit buds in the Bluecrop cultivar (Vaccinium corymbosum L.) taken at the end of the latent period before budding at the February 15 th during the -2015 growing season. In order to support the increase of the number of roots and their length the hardwood cuttings are treated with different IBA and NAA concentrations (1500, 3000, 4500 ppm), while a part of cuttings were untreated control. The number and the length of roots have increased in relation to the increase of concentration from 1500 to 3000 ppm followed by a decline of these values in concentrations over 3000 ppm. Respectively, the number of roots (8) and the higher values of root length (4.6 cm) are achieved in the turf–perlite substrate, IBA 3000 ppm (compared to the turf-only substrate). The presence of perlite helps the aeration of the substrate and supports biochemical and physiological processes which lead to the inducing of adventive roots. Regarding the number and length of roots an important variation for (p<0.05) was observed between different concentrations of IBA and NAA. In general the effect of IBA was a lot better than the effect of NAA.

Full textAbstract:
Hydrogen peroxide (H2O2) reactions on platinum nanoparticle-decorated carbon nanowalls (Pt-CNWs) under potential applications were investigated on a platform of CNWs grown on carbon fiber paper (CFP) using plasma-enhanced chemical vapor deposition. Through repeated cyclic voltammetry (CV), measurements of 1000 cycles using the Pt-CNW electrodes in phosphate-buffered saline (PBS) solution with 240 μM of H2O2, the observed response peak currents of H2O2 reduction decreased with the number of cycles, which is attributed to decomposition of H2O2. After CV measurements for a total of 3000 cycles, the density and height of CNWs were reduced and their surface morphology changed. Energy-dispersive X-ray (EDX) compositional mapping revealed agglomeration of Pt nanoparticles around the top edges of CNWs. The degradation mechanism of Pt-CNWs under potential application with H2O2 is discussed by focusing on the behavior of OH radicals generated by the H2O2 reduction.

Full textAbstract:
Security is one of the major concerns in banking sector where we can adapt the latest techniques like face recognition and RFID we can provide better security policies. In this paper we have proposed a model with two major security techniques. The First method provides security for the locker room door by face recognition using OpenCV. Face recognition is a particular type of biometric system that can be used to analyze the obtained information and identify the user uniquely by the trained images. In this proposed model the images of customers are trained. A Microsoft Lifecam HD-3000 is placed outside the locker room. This camera detects the human face using Haar Cascade Classifier and recognizes a customer using LBPH Algorithm. If a trained customer tries to enter then door is unlocked. The customer name is uploaded to cloud. The second method provides security to the cashier cabin by using MFRC522 RFID Module which is very easy to access which consumes less time and more secured compared to the existing system. When an authorized tag is recognized the door is unlocked for certain time period and the userid is uploaded to the cloud. By using these two techniques we can provide security for locker room and cashier cabins in any banking sector.

Full textAbstract:
Root-knot nematodes are obligate parasites, so changes at their feeding sites can limit their development. Alterations to feeding sites is one of the main actions taken by antagonistic plants. The aim of this study was to assess the response and histopathology of interactions between Meloidogyne javanica and the roots of Macrotyloma axillare cv. Java. The penetration and development of the nematode was assessed from 8 to 30 days after inoculation (DAI) with 3000 eggs + second-stage juveniles (J2) of M. javanica. The reproduction factor (RF) was assessed at 60 DAI, with two inoculation levels, 700 and 1000 eggs + J2, and the changes in the development and histopathology of M. javanica was assessed at 10, 15 and 30 DAI. Suscetible soybean was used as a control. The development of nematodes at the third (J3) and fourth juvenile (J4) stages was delay, despite the presence of J2 inside the roots, and no adult females were found in the M. axillare cv. Java roots. RF was 0.31 and 0.39 for M. axillare cv. Java and 3.40 and 4.52 for soybean at inoculation levels of 700 and 1000 eggs + J2, respectively. The feed cells in M. axillare cv. Java could not effectively nourish the nematode, which led to deformed females 30 DAI. The feed cells and nematode development, however, were normal in soybean. M. axillare cv. Java was resistant to M. javanica and had an antagonistic potential, because it did not prevent the nematode from penetrating the roots but had a negative effect on M. javanica due to the inefficiency of the feeding site.

RESUMO A implantação do sistema de sucessão de culturas, possibilitando a inserção de espécies vegetais antagonistas ou não hospedeiras à patógenos da soja no período de entressafra, é uma alternativa sustentável em sistemas de cultivo. Neste contexto, recomenda-se cuidado na seleção de plantas de sucessão que não possibilitem a multiplicação de nematoides, especialmente, os parasitas da soja, Pratylenchus brachyurus e Meloidogyne javanica. Desta forma, objetivou-se avaliar o potencial de redução da população de P. brachyurus e M. javanica, pelo cultivo de espécies utilizadas em sucessão com a soja, comparando-as com o crambe. Sementes de soja cv. 5909RR Nidera foram semeadas em vasos com capacidade para 18 L e após 15 dias foram inoculadas, em experimentos separados, com 1000 espécimes de P. brachyurus e 3000 ovos e eventuais juvenis de segundo estádio (J2) de M. javanica. Aos 60 dias da inoculação, a parte aérea das plantas foi descartada e as culturas de sucessão (milho cv. IPR114, feijão cv. IPR Tangará, nabo forrageiro, aveia-preta cv. IAPAR 61 e crambe cv. MS Brilhante) foram semeadas. As plantas foram cultivadas por 90 dias, quando a parte aérea foi cortada, semeando-se novamente a soja, a qual foi cultivada por mais 60 dias. No final desse período, as plantas foram retiradas dos vasos para determinação de parâmetros vegetativos e nematológicos na soja. A introdução do crambe no sistema de sucessão de culturas reduziu a população de P. brachyurus. A reprodução de M. javanica foi menor na sucessão com o crambe quando comparado com os demais sistemas, entretanto o mesmo apresentou elevado fator de reprodução.

Full textAbstract:
Tissue culture technique can be an important approach for the rapid propagation of Humulus lupulus L. (hop plant). The present study evaluated different culture media for hop plants (cv. Columbus) in vitro shoots multiplication, as well as ex vitro rooting and plantlets establishment under field conditions at Southern Brazil. The culture medium containing the plant growth regulator thidiazuron (TDZ) resulted in greater in vitro shoots multiplications (five shoots per explant). For microcuttings ex vitro rooting, indole-3-butyric acid (IBA) application at a concentration of 3000 mg L-1 resulted in higher rooting and survival percentages during acclimatization. After 90 days of acclimatization, the plantlets were transplanted under field conditions and had their development and productivity evaluated 122 days after transplanting. Micropropagated plants achieved 100% survival under field conditions. Nitrogen supply is highly necessary for hop plants initial development at Southern Brazil. Micropropagation is a viable technique for quality plantlet production of H. lupulus cv. Columbus.

Full textAbstract:
Ziel des Dissertationsprojekts war eine differenzierte Betrachtung des akademischen Selbstkonzepts in den naturwissenschaftlichen Fächern. Unter anderen wurden die Abgrenzung des akademischen Selbstkonzepts von Selbstwirksamkeitserwartungen, seine dimensionale Struktur, Geschlechtsunterschiede sowie seine Beeinflussung durch die Konzeption des Naturwissenschaftsunterrichts und durch dimensionale Vergleiche untersucht. Im Mittelpunkt der ersten Teilstudie stand die Frage nach der empirischen Trennbarkeit von akademischem Selbstkonzept und Selbstwirksamkeitserwartung in den Naturwissenschaften. Es konnte gezeigt werden, dass die beiden Konstrukte messtheoretisch klar abgrenzbar sind und differentielle Zusammenhänge zu anderen Konstrukten aufweisen: Das Selbstkonzept wurde stärker durch soziale Vergleiche, Selbstwirksamkeitserwartungen stärker durch Unterrichtscharakteristika beeinflusst. In der zweiten Teilstudie wurde die fachspezifische Ausdifferenzierung naturwissenschaftlicher Selbstkonzepte untersucht. Es konnte gezeigt werden, dass Schüler zwischen den Selbstkonzeptfacetten in Biologie, Chemie und Physik unterscheiden und diese drei Facetten differentielle Zusammenhänge zu Leistungsmaßen und zum Geschlecht aufweisen. Die dritte Teilstudie beschäftigte sich mit interdisziplinärem Naturwissenschaftsunterricht als Einflussfaktor auf die Selbstkonzeptstruktur. Dabei konnte gezeigt werden, dass Schüler, die interdisziplinär beschult werden, deutlich höhere Zusammenhänge zwischen den Selbstkonzeptfacetten in Biologie, Chemie und Physik aufweisen als Schüler, die getrennt in den drei Fächern unterrichtet werden. In der vierten Teilstudie wurde der Einfluss dimensionaler Leistungsvergleiche auf naturwissenschaftliche Selbstkonzepte sowie Mathematik und Deutsch untersucht. Es zeigten sich Kontrasteffekte zwischen Mathematik, Physik und Chemie auf der einen und Deutsch auf der anderen Seite. Die Befunde haben Implikationen für die Theorie dimensionaler Vergleiche.In this dissertation project, academic self-concept in the science subjects is scrutinized. Amongst others, its separability from self-efficacy, its dimensionality, and gender differences were examined. The dissertation includes four research articles. All are based on data from large-scale assessment studies. In the first research article, we examined whether academic self-concept and self-efficacy in the science subjects can be distinguished empirically. We found a moderate positive correlation between self-concept and self-efficacy in science, advocating distinguishable constructs. Furthermore, science self-concept was better predicted by the average peer achievement, whereas science self-efficacy was more strongly affected by inquiry-based learning opportunities. The second research article focused on the internal structure of academic self-concept in the sciences. It could be shown that students differentiate between their abilities in biology, chemistry and physics and that the subject-specific self-concept facets are differentially related to achievement and gender. For example, stereotypical gender differences in favor of boys were found for chemistry and physics. The effect of interdisciplinary science teaching on the structure of academic self-concept in the sciences was examined in the third research article. Students who were taught science as an interdisciplinary subject showed substantially higher relations between the self-concept facets in biology, chemistry, and physics than students who were taught these subjects separately. In the fourth research article, the effects of dimensional comparisons on academic self-concepts in the sciences as well as mathematics and German were scrutinized. We found contrast effects between the German and math, physics, and chemistry as well as assimilation effects between math, physics, and chemistry. The results further advance dimensional comparison theory.

Full textAbstract:
Positive Interaktionen zwischen jüngeren und älteren Erwachsenen scheinen gefährdet, da Untersuchungen einen Mangel an Einfühlungsvermögen gegenüber älteren Menschen nahelegen. Eine Reihe von Faktoren könnte für die Verringerung oder Abwesenheit von Empathie von jüngere Erwachsenen verantwortlich sein: Studie 1 betrachtete die Wirkung von Gesichtsfalten und Stereotypen auf die Dekodierung und Imitation von emotionalen Gesichtsausdrücken und fand heraus, dass Imitationsreaktionen für ältere Erwachsene auftraten, trotz des Einflusses von Falten und Stereotypen auf die Dekodierung. Studie 2 untersuchte den Einfluss des affiliativen Kontextes in Interaktionen zwischen jungen und alten Erwachsenen und nahm an, dass der Emotionsausdruck per se (freudig vs. ärgerlich) sowie die Beziehung zwischen Beobachter und Darsteller (Eigengruppe vs. Fremdgruppe) sich auf Gesichtsmimikry in lebensechten Interaktionen auswirken. Es konnte gezeigt werden, dass Mimikry für freudige Ausdrücke älterer Erwachsener während der beiden emotionalen Ereignisse (freudig vs. ärgerlich) stattfand. Allerdings war Mimikry im freudigen Ereignis stärker gegenüber jungen Erwachsenen im Vergleich zu älteren Erwachsenen ausgeprägt, wohingegen keine Unterschiede in Mimikry im ärgerlichen Ereignis auftraten. Studie 3 untersuchte empathischen Fähigkeiten von älteren im Vergleich zu jüngeren Erwachsenen und fand keine Unterschiede in der affektiven Empathie, obwohl die Dekodierung einiger Emotionen bei den älteren Teilnehmern reduziert war. Insgesamt zeigen die Ergebnisse, dass affektive empathische Reaktionen gegenüber älteren Menschen unabhängig von der reduzierten Akkuratheit der Emotionseinschätzung sowie vom affiliativen Kontext im Wesentlichen intakt sind und dass ältere Erwachsene die über gleichen affektiven Fähigkeiten verfügen. Somit liefert diese Arbeit einen positiveren Ausblick für intergenerationale Interaktionen als bisher gedacht.Positive interactions between younger and older adults seem to be at risk as previous research suggests a lack of empathy to the elderly. A number of elements might be accountable for the reduction or absence of empathy by younger adults: Study 1 focused on the effect of wrinkles and stereotypes on decoding accuracy and facial mimicry of emotional facial expressions. It revealed that wrinkles and stereotypes have an impact on decoding accuracy, however facial mimicry reactions to the emotion expressions of older adults were present regardless of those decoding biases. Study 2 focused on the affiliative context of interactions between younger and older adults, and suggested that the type of emotion display (happy vs. angry) as well as the observer’s relationship to the expresser (in-group vs. out-group member) impacted on facial mimicry in real-life interactions. It revealed that mimicry of happy expressions of older adults was present during the two emotional events (happy and angry). However, mimicry of younger compared to older adults was stronger in the happy event, whereas no difference occurred in mimicry in the angry event. Study 3 investigated empathic capabilities of older compared to younger adults and found no differences in affective empathy, although decoding accuracy was reduced for some emotions in the older participant sample. Collectively, these results indicate that affective empathic responding via facial mimicry toward the elderly is essentially intact regardless of reduced decoding accuracy for older faces and affiliative context. They further indicate that older adults possess the same affective capabilities as younger adults. In sum, this work provides a more positive outlook for intergenerational interactions than previously suggested.

Full textAbstract:
Die Dissertation präsentiert ein konzeptuelles Rahmenmodell zur Untersuchung von Narzissmus in sozialen Interaktionen. Es differenziert zwischen situations-invarianten (z.B. Narzissmus) und situations-variierenden Variablen (z.B. positives Feedback) zur Vorhersage narzisstischen Verhaltens. Es bildete die Grundlage für drei Studien entlang der Zeitlinie von sozialen Interaktionen (d.h., zu Beginn, im täglichen Verlauf, innerhalb von langjährigen Freundschaften). Studie 1 untersuchte, ob sich der Einfluss von Narzissmus in Situationen reduziert, die starke Hinweisreize für die Angemessenheit von Selbstdarstellung beinhalten, wie die Trait Activation Theory (Tett & Burnett, 2003) vermuten würde. Es wurde geschlussfolgert, dass der grandiose Kern von Narzissmus unempfindlich gegenüber dem Einfluss situations-variierender Variablen war (hinsichtlich der Reizstärke für Selbstdarstellung). Studie 2 erforschte Narzissmus innerhalb sozialer Interaktionen im Alltag mit Hilfe eines experience-sampling Designs in drei aufeinander aufbauenden Teilstudien. Im Gegensatz zu den Befunden aus Studie 1 zeigten die Ergebnisse der zweiten Studie, dass es einen starken situativen Einfluss auf die Expression von State Narzissmus gab - unabhängig vom individuellen Narzissmus-Niveau. Zum Beispiel erhöhten sowohl positives als auch negatives Feedback das State Narzissmus Level aufgrund von Selbsterhöhungs- oder Selbstschutzmechanismen. Die Ergebnisse stellen die Rolle von Trait Selbstwert auf State Narzissmus infrage, unterstreichen aber die Wichtigkeit von State Selbstwert. Studie 3 demonstrierte, dass mit einer zunehmenden distinktiven Ähnlichkeit (d.h., die Ähnlichkeit in den normabweichenden Aspekten der beiden Freunde) im Narzissmus zweier bester Freunde die distinktive Ähnlichkeit in deren Big Five Profilen ebenfalls ansteigt. Es werden Implikationen für situations-spezifische Aspekte von Narzissmus innerhalb von langjährigen Freundschaften diskutiert.The present dissertation presents a conceptual framework for the study of narcissism in social interactions (NARCissism In Situations: NARCIS). This framework differentiates between situation-invariant variables (e.g., trait narcissism) and situation-varying variables (e.g., positive feedback) for the prediction of narcissistic behavior. It built the theoretical basis for three studies that were placed along the time line of social interactions (i.e., at the beginning, in the daily intercourse, and within long-term friendships). Study 1 examined whether the manifestation of individual differences in narcissism reduce in situations that include strong cues for the appropriateness of self-promotional behavior, as trait activation theory (Tett & Burnett, 2003) would expect. It was concluded that the grandiose core of narcissism was insensitive to the influence of situation-varying variables in terms of cue strength for self-promotion. Study 2 investigated narcissism within social interactions in everyday life following an experience-sampling design in three consecutive substudies. In contrast to the findings from the first study, results of Study 2 showed that there was a strong situational influence on the expression of state narcissism - regardless of the individual’s narcissism trait level. For example, both negative social feedback and positive feedback increased state narcissism levels due to ego protection or ego boosting mechanisms. The results question the role of trait self-esteem but underscore the importance of state self-esteem on state narcissism. Last but not least, Study 3 demonstrated that with increasing distinctive similarity (i.e., the similarity in the two friends’ norm-deviating parts) in narcissism of two best friends’ their distinctive similarities in their Big Five profiles augmented as well. Implications for situation-specific aspects of narcissism within long-term friendships are discussed.

Full textAbstract:
Empathische Reaktionen auf emotionale Gesichtsausdrücke werden vom Alter beeinflusst. In Bezug auf die kognitive Komponente der Empathie wurde eine Einschränkung bei der Erkennung emotionaler Gesichtsausdrücke sowohl für ältere Beobachter als auch für ältere Gesichter berichtet. Manche Studien berichten auch einen Effekt der Alterskongruenz, d.h. eine bessere Erkennung von Emotionen bei der eigenen Altersgruppe. Das erste Ziel der vorliegenden Dissertation war es, Mechanismen, die diesen Effekten zugrunde liegen könnten, zu untersuchen. Das zweite Ziel war es, zu untersuchen, ob auch die affektive Komponente der Empathie vom Alter beeinflusst wird. Studie 1 gibt einen Überblick über frühere Forschungsarbeiten. Studie 2 beschäftigte sich mit der Rolle von altersbezogenen Antwortverzerrungen, d.h. Altersunterschieden bei der Attribuierung bestimmter Emotionen. Effekte des Alters der Beobachter und der Gesichter auf die Erkennung von Trauer waren auf Antwortverzerrungen zurückzuführen. Allerdings trat eine bessere Erkennung von Trauer bei der eigenen Altersgruppe auf, die unabhängig von Antwortverzerrungen war. Studie 3 untersuchte neuronale Prozesse, die diesem Effekt der Alterskongruenz zugrunde liegen könnten. Bei traurigen Gesichtern wurde ein Effekt der Alterskongruenz für späte Verarbeitungsstadien gefunden, der möglicherweise eine höhere Relevanz trauriger Gesichter der eigenen Altersgruppe widerspiegelt. Studie 4 untersuchte, ob auch affektive Reaktionen, gemessen mit Gesichtsmimikry, vom Alter beeinflusst werden. Ältere Beobachter zeigten eine Beeinträchtigung in der Emotionserkennung, nicht jedoch in den affektiven Reaktionen. Insgesamt weisen diese Ergebnisse auf altersbezogene Defizite bei kognitiven und neuronalen Reaktionen hin; allerdings gab es kaum Alterseffekte auf affektive Reaktionen. Also lassen die Ergebnisse insgesamt trotz Schwierigkeiten bei der Emotionserkennung Optimismus bezüglich der intergenerationalen Empathie zu.Empathic reactions to emotional facial expressions differ according to age. Concerning the cognitive component of empathy, decoding of emotional facial expressions was reported to be impaired both for older observers and older faces. Some studies also reported an own-age advantage, i.e., higher decoding accuracy for the own compared with other age groups. The first aim of the present dissertation was to explore possible mechanisms underlying these age effects. The second aim was to explore whether the affective component of empathy is affected by age as well. Study 1 summarizes previous research. Study 2 explored the role of age-related response bias, that is, age differences in the attribution of specific emotions. It showed that effects of the observers'' and the faces'' ages on decoding sadness were due to age-related response bias. However, an own-age advantage on decoding sadness occurred, which was independent of response bias. Study 3 explored the neurofunctional processes underlying this own-age advantage. It revealed an own-age effect on late processing stages for sadness, which may be due to an enhanced relevance of sad own-age faces. Study 4 explored whether affective responding in terms of facial mimicry is affected by age as well. It revealed an age-related decline in decoding accuracy, but not in affective responding. Taken together, these results suggest age-related deficits in cognitive and neural responses to emotional facial expressions. However, age had little influence on affective responding. Thus, despite difficulties in emotion decoding, these results allow for some optimism regarding intergenerational empathy.

Achtsamkeit wird mit vielen positiven Effekten für das psychische Wohlbefinden assoziiert, wobei Fähigkeiten wie Emotionsregulation (ER) und soziale Kognition (SC) zu den wichtigsten Mechanismen gehören. In der vorliegenden Doktorarbeit wurde die Beziehung zwischen Achtsamkeit, ER und SC mit verschiedenen methodischen Ansätzen untersucht. In Studie I wurde mithilfe von Literatur und empirischen Modellen die Beziehung zwischen Achtsamkeit und ER ausgearbeitet und verschiedene psychologische und neurokognitive Mechanismen diskutiert. Studie II zielte darauf ab den ER-Mechanismus bei „Trait-Achtsamkeit“ zu entschlüsseln. Hier zeigte sich, dass es sowohl bei Probanden mit einer Borderline-Persönlichkeitsstörung als auch bei gesunden Teilnehmern einen mediierenden Effekt von Selbstmitgefühl gab, der Achtsamkeit mit ER-Merkmalen verband. Studie III untersuchte den Zusammenhang zwischen ER und SC mit Hilfe von Verhaltens- und Neuroimaging-Experimenten, mit Fokus auf dem Konzept der sozialen ER (die Fähigkeit, die Emotionen anderer zu modulieren). Es zeigte sich, dass bei der Regulierung der Emotionen anderer der eigene Stress reduziert wird, wobei wichtige "soziokognitive" Hirnregionen (z.B. Precuneus) an der Vermittlung dieser Effekte beteiligt sind. Studie IV untersuchte im Rahmen einer Neuroimaging-basierten randomisierten Kontrollstudie ER-Mechanismen während einer achtsamkeitsbasierten Intervention (MBI). Die Studie zeigte eine durch die MBI induzierte ER-Verhaltensplastizität im Gehirn, sowohl für die Eigen- als auch für die soziale ER. Ein Effekt im Vergleich zu SC (kognitive und emotionale Empathie) wurde nicht gezeigt. Unter Einbezug aller Ergebnisse wurde ein Modell postuliert, das den Austausch und die Regulierung von Emotionen im Kontext von sozialen Interaktionen integriert. Die Dissertation bietet neue Einblicke in die ER-Mechanismen der Achtsamkeit und beleuchtet die individuellen Determinanten sozialer Prozesse durch das Zusammenbringen von ER und SC.Mindfulness, the capacity to fully attend to the present experience, has been linked to a myriad of mental health benefits, being abilities such as emotion regulation (ER) and social cognition (SC) of the main potential active mechanisms. The current doctorate thesis investigated the relationship between mindfulness and ER and SC using a range of methodological approaches from trait level individual differences to behavioral and brain mechanisms. Study one explored the relationship between mindfulness and ER by examining the diverse literature and empirical models, discussing different psychological and neuro-cognitive mechanisms. Study two intended to unravel the ER mechanism of trait mindfulness, showing in both borderline personality and healthy subjects the mediating effect of self-compassion linking mindfulness and ER traits. Study three further investigated the link between ER and SC using behavioral and neuro-imaging experiments, addressing the notion of social ER (the capacity to modulate others’ emotions). It showed that when regulating others’ emotions, an individual’s own distress is reduced, being key ‘sociocognitive’ brain regions (i.e. precuneus) engaged in mediating these effects. Study four investigated the fine-grained ER mechanisms of a mindfulness-based intervention (MBI), comparing the MBI with a reading group (READ), in the context of a neuroimaging-based randomized controlled trial. This study revealed ER brain behavioral plasticity induced by the MBI, for both self and social ER. It also showed a lack of effect over SC (cognitive and emotional empathy). Articulating overall findings, a model that integrates exchanges and regulation of emotions in the context of social interactions is proposed. The dissertation offers new insights into mindfulness’ ER mechanisms, from dispositions to neuro-behavioral levels, and also sheds light onto individual level determinants of social processes, linking ER and SC.

Full textAbstract:
Das Konzept der interpersonellen Fähigkeiten bezieht sich auf Leistungsaufgaben der sozialen Kognition. Diese Aufgaben messen die Fähigkeiten Gesichter zu erkennen und sich diese zu merken sowie Emotionen zu erkennen und diese auszudrücken. Ziel dieser Dissertation war die Untersuchung des Einflusses von interpersonellen Fähigkeiten auf soziale Entscheidungen. Ein besonderer Fokus lag auf der Quantifizierung von individuellen Unterschieden in zugrundeliegenden neuronalen Mechanismen. Studie 1 erweiterte bestehende Evidenz zu Beziehungen zwischen psychometrischen Konstrukten der Gesichterkognition und Ereigniskorrelierten Potentialen, welche mit den verschiedenen Stadien der Gesichterverarbeitung (Enkodierung, Wahrnehmung, Gedächtnis) während einer Bekanntheitsentscheidung assoziiert sind. Unsere Ergebnisse bestätigen eine substantielle Beziehung zwischen der N170 Latenz und der Amplitude des frühen Wiederholungseffektes (ERE) mit drei Faktoren der Gesichterkognition. Je kürzer die N170 Latenz und je ausgeprägter die ERE Amplitude, umso genauer und schneller ist die Gesichterkognition. Studie 2 ergab, dass die Fähigkeit ängstliche Gesichter zu erkennen sowie die generelle spontane Expressivität während der sozialen Interaktion mit prosozialen Entscheidungen korreliert. Sensitivität für das Leid anderer sowie emotionale Expressivität scheinen reziproke Interaktionen mit Gleichgesinnten zu fördern. Studie 3 bestätigte das Modell der starken Reziprozität, da Prosozialität die negative Reziprozität im Ultimatum Spiel beeinflusste. Unter der Verwendung von Strukturgleichungsmodellen entdeckten wir, dass Menschen mit ausgeprägter Reziprozität eine größere Amplitude der relativen feedback-negativity auf das Gesicht von Spielpartnern zeigen. Insgesamt sprechen die Ergebnisse dafür, dass die etablierten individuellen Unterschiede in den Verhaltensmaßen der interpersonellen Fähigkeiten zum Teil auf individuelle Unterschiede in neuronalen Mechanismen zurückzuführen sind.The concept of interpersonal abilities refers to performance measures of social cognition such as the abilities to perceive and remember faces and the abilities to recognize and express emotions. The aim of this dissertation was to examine the influence of interpersonal abilities on social decisions. A particular focus lay on the quantification of individual differences in brain-behavior relationships associated with processing interpersonally relevant stimuli. Study 1 added to existing evidence on brain-behavior relationships, specifically between psychometric constructs of face cognition and event-related potentials associated with different stages of face processing (encoding, perception, and memory) in a familiarity decision. Our findings confirm a substantial relationship between the N170 latency and the early-repetition effect (ERE) amplitude with three established face cognition ability factors. The shorter the N170 latency and the more pronounced the ERE amplitude, the better is the performance in face perception and memory and the faster is the speed of face cognition. Study 2 found that the ability to recognize fearful faces as well as the general spontaneous expressiveness during social interaction are linked to prosocial choices in several socio-economic games. Sensitivity to the distress of others and spontaneous expressiveness foster reciprocal interactions with prosocial others. Study 3 confirmed the model of strong reciprocity in that prosociality drives negative reciprocity in the ultimatum game. Using multilevel structural equation modeling in order to estimate brain-behavior relationships of fairness preferences, we found strong reciprocators to show more pronounced relative feedback-negativity amplitude in response to the faces of bargaining partners. Thus, the results of this dissertation suggest that established individual differences in behavioral measures of interpersonal ability are partly due to individual differences in brain mechanisms.

Mestrado em Economia e Gestão da Ciência, Tecnologia e InovaçãoA pesquisa desenvolvida, no âmbito do mestrado, visa estudar a mobilidade dos cientistas enquanto dimensão chave do processo de produção e circulação de conhecimento. A formação de recursos humanos em ciência e a mobilidade desses recursos são, actualmente, questões prioritárias nas agendas políticas nacionais e internacionais. O fenómeno da mobilidade não é contudo linear. A mobilidade é actualmente apresentada como um mecanismo útil e encorajador de excelência e mecanismo decisivo para a difusão do conhecimento e sua integração nos Sistemas Nacionais de Inovação (CEC, 2001), onde o impacto do desenvolvimento e incorporação de recursos humanos altamente qualificados em ciência e tecnologia tem vindo a ser, nas últimas décadas, um factor de crescente valor estratégico (Godinho, 1999). Com este quadro de referência procura-se explorar a mobilidade científica enquanto fenómeno multi-dimensional e multi-direccional e a sua relação com a produtividade, enquanto activo económico. Nesta dissertação é explanado o mapeamento do fenómeno da mobilidade, enquanto objecto de análise das ciências sociais, sendo um objectivo expresso desta tese demonstrar tanto o carácter complexo do fenómeno como as várias dimensões em jogo. É também corpo desta dissertação mostrar a utilidade e a necessidade de uma aproximação empírica da abordagem. Tendo em conta o carácter pouco explorado do fenómeno, avança-se com um de estudo de caso que utiliza uma abordagem exploratória. A recolha de dados utilizados assenta em Curricula Vitae (CVs) de investigadores e em entrevistas biográficas. O objectivo final deste estudo é contribuir com conhecimento empírico, relativo ao caso português, sobre as trajectórias de mobilidade dos investigadores, abordando as motivações individuais dos actores inerentes às suas opções de mobilidade, e sobre a relação entre a mobilidade e produtividade científica.
This research aims to study the scientists' mobility as a key dimension in the process of knowledge creation and circulation. Training human resources in science and the mobility of these resources are a priority nowadays, raising discussions in national and international political agendas. Nevertheless, the mobility phenomenon is not linear. Mobility is presented as a useful and inspiring mechanism of excellence, decisive for the dissemina¬tion and integration of the knowledge in the National Innovation Systems (CEC, 2001). The impact of the development and incorporation of highly qualified human resources in science has been fore¬seen, in the last decade, as a key factor supporting an increasing strategic value. Having this frame¬work in mind, the aim of this research is to explore the scientific mobility as a multi-directional and multi-dimensional phenomenon and its relation with productivity, as an economic asset. In this research, the mobility phenomenon is mapped as an object of analysis for social science. Therefore, a goal in this work is to express the role of multiple variables supporting the phenomenon. Additionally, this research also demonstrates the requirement for an empirical approach towards the mobility phenomenon. Due to the unexplored character of the phenomenon, a case study proposal using an exploratory ap¬proach is brought forward. This approach employs and analyzes data sets collected from researcher's Curriculum Vitae (CVs) and biographical interviews. Finally, the goal is to add empirical knowledge, to the Portuguese scenario, regarding scientific mobility trajectories, exploring actor's individual moti¬vations regarding their personal mobility choices, and the relation between mobility and scientific productivity.

Full textAbstract:
Ein gesundes Alter(n) ist sowohl auf individueller Ebene als auch auf gesellschaftlicher Ebene von großer Relevanz. So wächst die Bedeutung von Prävention und Gesundheitsförderung bis ins hohe Alter – einerseits, um die Autonomie, Selbstbestimmtheit, soziale Teilhabe und Lebensqualität des älteren Menschen aufrecht zu erhalten und andererseits, um den durch den demografischen Wandel bedingten gesundheitspolitischen Herausforderungen begegnen zu können. Dabei weist der gesundheitliche Status im Alter neben hoher Vulnerabilität eine Vielzahl an Ressourcen und somit Ansatzpunkte für präventive und gesundheitsförderliche Interventionen auf. Technische Innovationen bieten hier ein wachsendes Potenzial, um Maßnahmen dieser Art zu stützen. Zur Erschließung des neuartigen Themenfeldes werden die Ergebnisse dreier Einzeluntersuchungen berichtet, in welchen sowohl qualitative als auch quantitative Methoden angewandt werden. Mit Hilfe der Durchführung von Expertinneninterviews werden Bedarf und Potenzial innovativer Technik in Prävention und Gesundheitsförderung für Ältere und erste Anforderungen an eine solche Technik erfasst. Eine innovative Möglichkeit zur Umsetzung präventiver und gesundheitsförderlicher Interventionen bieten digitale Bewegungsspiele. So werden darauffolgend im Rahmen einer quasi-experimentellen Kohortenstudie gesundheitsbezogene Veränderungen durch das Spielen sog. Serious Games im Setting (teil-)stationäres Pflegewohnen evaluiert. Die Ergebnisse zeigen erste gesundheitsförderliche Tendenzen. Innerhalb einer Fokusgruppe werden abschließend drei digitale Bewegungsspielsysteme unter Beachtung zielgruppenspezifischer Bedarfe bewertet und notwendige Ressourcen für den erfolgreichen Einsatz im Anwendungskontext erarbeitet. Um die neugewonnenen Erkenntnisse in nachhaltiger Form nutzbar zu machen, werden diese in einem Anforderungskatalog für die erfolgreiche Implementierung eines digitalen Bewegungsspiels im Kontext der Pflege zusammengefasst.Being healthy in old age and aging healthily is of great relevance at both the individual and societal level. Thus, the importance of prevention and health promotion even in an old age is growing - on the one hand, to maintain the autonomy, self-determination, social participation and quality of life of the elderly and, on the other hand, to be able to meet the health policy challenges caused by demographic change. Health in old age is not only highly vulnerable but also offers a multitude of resources and starting points for preventive and health-promoting interventions. Technical innovations offer a growing potential to support measures of this kind. In order to open up this new field of research, the results of three individual studies are reported, in which both qualitative and quantitative methods are applied. By conducting expert interviews, the need and potential of innovative technology in prevention and health promotion for the elderly as well as first requirements for such a technology are identified. Digital exercise games offer an innovative possibility for the implementation of preventive and health-promoting interventions. Subsequently, health-related changes caused by playing digital exercise games, so-called serious games, in the setting of nursing care are evaluated within the framework of a quasi-experimental cohort study. The results show first health-promoting tendencies through playing serious games. Last, three digital exercise game systems will be evaluated in a focus group on the basis of the needs of the target group. Additionally, the necessary resources for successful use of such systems in a real application context are developed in a participatory way. In order to make the newly gained knowledge usable in a way that is sustainable and relevant for practical use, it is then summarized in a catalogue of requirements for the successful implementation of a digital exercise game in the nursing environment.

Full textAbstract:
Abstract Several improvements to the mathematical model of the indicator process taking place at a diesel engine cylinder are proposed. The thermodynamic behavior of working medium is described by the equation of state, valid for real gases. Mathematical dependencies between thermal parameters (P, T, v) and caloric parameters (u, h, cv, cp) have been obtained. An improved mathematical model, based on the first law of thermodynamics, has been developed, taking into account working medium imperfections. The numerical solution of the simultaneous differential equations is made by a method of Runge-Kutta type. The computing procedure is iterative. Calculations in respect to the caloric parameters (u, h, cv and cp) for various gases under pressure up to 25 MPa and temperature up to 3000°C have been carried out. The results show, that there are significant differences between the values, calculated by equations for ideal gases, and the proposed equations for real gases under high pressure and temperature. Actual applied problems for two-stroke turbocharged engines Sulzer-RLB66 and 8DKRN 74/160 have been solved. The comparison between the experimental data and numerical results show very good agreement. The numerical experiments show that if the pressure is above 8–9 MPa, the working medium imperfections must be taken into consideration.

Full textAbstract:
PS is bound to one (C4bp) and possibly two (protein S binding protein) other proteins in plasma, necessitating the validation of any assay, both by standard criteria and for its ability to measure the different forms of PS in plasma. Murine monoclonal antibody PS-2a was adsorbed to solid phase microtiter plate wells at 10 ug/ml, pH 9.6. For the assay, affinity purified PS standard, free of C4bp, or plasma samples were incubated with 125 I labelled PS.Serial dilutions of pooled normal plasma paralleled the standard curve. Competition studies with other vitamin K dependent coagulation proteins, anti-thrombin III, C4bp and bone Gla protein showed no significant crossreactivity. When 5.7 ug of PS was added to 10 normal plasmas the mean recovery was 5.86 ± 0.8 ug/ml. Sensitivity was 0.03 ug/ml at the working plasma dilution (1/64). Normal pooled plasma had a mean of 15 ug/ml with an intra-assay CV of 5.7%. The normal range based on 61 normal plasmas is 9.5-24 ug/ml. The mean of 24 warfarinized plasmas was 8.9 ug/ml (1 SD = 3.5)Normal pooled plasma was totally depleted of PS using anti-PS-2a coupled to sepharose 4B at 5mg/ml. Depleted and undepleted normal pooled plasmas were then compared to a standard curve of purified PS in a reduced, SDS PAGE Western Blot utilizing a rabbit polyclonal anti PS. This experiment demonstrated that the monoclonal antibody used in the assay totally depleted the pooled plasma of all forms of PS and therefore appears to recognize an epitope on PS not involved in its binding interactions with other plasma proteins.PS and C4bp were measured following HPLC using a Beckman TSK-3000 column for rapid separation. In pooled plasma 70% of PS appeared bound to C4bp.(Supported by NIH Grant HL 35058)
