Organ characteristics of male growing male pigs fed low crude protein and low energy diets supplemented with multi-enzyme were determined using 36 hybrid (Landrace x Large white) male pigs of 8-10 weeks old. Two metabolizable energy (3000 and 2600 Kcal ME/kg) and three crude protein levels (14, 16 and 18 % CP) were used to formulate six dietary treatments; T1: control (3000 Kcal ME/kg; 18 % CP), T2 (3000 Kcal ME/Kg; 16 % CP), T3 (3000 Kcal ME/kg; 14 % CP), T4 (2600 Kcal ME/kg; 18 % CP), T5 (2600 Kcal ME/kg; 16 % CP) and T6 (2600 Kcal ME/kg; 14 % CP). The enzyme was added to all the treatments at 1g/kg diet except the control. The treatments were replicated three times with two pigs per replicate. The experiment was a 2 x 3 factorial. The pigs were starved for 12 hours but allowed access to drinking water, stunned and bled completely. It was cut open though the thorax region along the underline to the abdomen, exposing the entire internal organs and GIT contents. The heart, lungs, liver, kidneys, spleen and other internal organs were examined, carefully removed and weighed with a sensitive electronic kitchen scale, model SF-400. Higher (P <0.05) live weight (33500.00g), with lower (P <0.05) mean values for heart and viscera were recorded in male growing pigs fed T4. Male growing pigs fed with T3 and T6 had lower (P<0.05) live weight (12200.00g and 11500.00g), and higher (P<0.05) relative internal organs. Male growing pigs fed 14 % CP diets (T3 and T6) with their corresponding metabolizable energy levels (3000kcal and 2600kcal) recorded higher (P<0.05) heart and viscera's values. Keeping growing (male) pigs on low crude protein diets (14 %) supplemented with multi-enzyme, irrespective of the energy levels, did not improve live weight but increased relative organ weight.
Les caractéristiques des organes de porcs mâles en croissance nourris à faible en protéines brutes et en énergie mais plutôt supplémentée en multi-enzymes ont été déterminées en utilisant 36 porcs mâles hybrides (Landrace x Large white) âgés de 8 à 10 semaines. Deux énergies métabolisables (3000 et 2600 Kcal ME / kg) et trois niveaux de protéines brutes (14, 16 et 18% CP) ont été utilisés pour formuler six traitements diététiques ; T1 : contrôle (3000 Kcal ME / kg ; 18% CP), T2 (3000 Kcal ME / Kg ; 16% CP), T3 (3000 Kcal ME / kg ; 14% CP), T4 (2600 Kcal ME / kg ; 18 % CP), T5 (2600 Kcal ME / kg ; 16% CP) et T6 (2600 Kcal ME / kg ; 14% CP). L'enzyme a été ajoutée à tous les traitements à raison de 1 g / kg de régime sauf le témoin. Les traitements ont été répliqués trois fois avec deux porcs par réplica. L'expérience était une factorielle 2 x 3. Les porcs ont été affamés pendant 12 heures mais ont eu accès à l'eau potable, étourdis et saignaient complètement. Il a été ouvert à travers la région du thorax le long du trait de soulignement jusqu'à l'abdomen, exposant l'ensemble des organes internes et le contenu du 'GIT'. Le cœur, les poumons, le foie, les reins, la rate et d'autres organes internes ont été examinés, soigneusement prélevés et pesés avec une balance de cuisine électronique sensible, modèle SF-400. Un poids vif plus élevé (P <0,05) (33500,00 g), avec des valeurs moyennes plus faibles (P <0,05) pour le cœur et les viscères ont été enregistrés chez des porcs en croissance mâles nourris au T4. Les porcs mâles en croissance nourris avec T3 et T6 avaient des organes internes relatifs inférieurs (P <0,05) (12 200,00 g et 11500,00 g) et supérieurs (P <0,05). Les porcs mâles en croissance nourris avec 14% de régimes 'CP' (T3 et T6) avec leurs niveaux d'énergie métabolisables correspondants (3000 kcal et 2600 kcal) ont enregistré des valeurs cardiaques et viscérales plus élevées (P <0,05). Le fait de garder les porcs en croissance (mâles) avec des régimes pauvres en protéines brutes (14%) supplémentés en multi-enzymes, quels que soient les niveaux d'énergie, n'a pas amélioré le poids vif mais augmenté le poids relatif des organes

Cihateup (West Java highland) and Rambon (West Java lowland) ducks are two local ducks which are commonly raised by farmers in West Java under extensive systems. The decline of land availability as a result of increasing human population has meant that the ducks should be raised under intensive system. An experimental research was conducted to evaluate the effect of energy-protein balance in the diet on semen characteristic of Cihateup and Rambon drakes under restricted water system (intensive system). The research was designed in Completely Randomized Design; there were six energy-protein balance in the diets as treatment, which were G1 ( 3000 kcal/kg ME, 20 % CP); G2 ( 3000 kcal/kg ME, 16 % CP); G3 ( 3000 kcal/kg ME, 13.5% CP); G4 (2700 kcal/kg ME, 20 % CP); G5 (2700 kcal/kg ME, 16 % CP); and G6 ( 2700 kcal/kg ME, 13.5 % CP); each treatment was replicated three times. Semen was collected when the drakes reached the age of nine months and semen evaluation for volume semen, sperm motility and sperm abnormality was conducted. The results show that semen characteristics show that the highest motility was produced by G5 (2700 kcal/kg ME, 16 % CP) for Cihateup drakes and G6 ( 2700 kcal/kg ME, 13.5 % CP) for Rambon drakes. There was no significant different effect among treatments on abnormality of Cihateup drakes semen; anyhow G5 (2700 kcal/kg ME, 16 % CP) can be considered as the best diet for Rambon drakes based on its semen abnormality. It can be concluded that at feeding diet containing similar Metabolizable Energy level, Cihateup drakes required higher protein level than Rambon drakes to produce a good quality of semen.Keywords: energy-protein balance, west java local drakes, semen

One of the reliable information for evaluating nutritional status, performance and physiological state of farm animals to nutrient utilization is through haematological indices assessment. Haematological parameters of grower pigs fed low crude protein and low energy diets supplemented with multi-enzyme (enziblend plus+) were determined using 36 hybrid (Landrace x Large white) male pigs of 8-10 weeks old. Two metabolizable energy (3000 and 2600 Kcal ME/kg) and three crude protein levels (18, 16 and 14 % CP) were used to formulate Six dietary treatments; T1 (3000 Kcal ME/Kg; 18 % CP), T2 (3000 Kcal ME/Kg; 16 % CP+ 1g of enzyme/kg diet), T3 (3000 Kcal ME/Kg; 14 % CP+ 1g of enzyme/kg diet), T4 (2600 Kcal ME/Kg; 18 % CP + 1g of enzyme/kg diet), T5 (2600 Kcal ME/Kg; 16 % CP + 1g of enzyme/kg diet) and T6 (2600 Kcal ME/Kg; 14 % CP + 1g of enzyme/kg diet). The treatments were replicated three with two pigs per replicate. The experiment was a 2 x 3 factorial, and T1 served as the control. Blood samples were collected (3mls) via the ear vein from one pig in each replicate, three from treatment for haematological analysis. The results of this study recorded significant differences (P<0.05) in most of the hematological parameters evaluated, except in mean corpuscular haemoglobin concentration (MCHC) and basophile counts of the pigs. Grower pigs fed T2 and T4 diets recorded significantly (P<0.05) higher packed cell volume (PCV) (40.15% and 40.22%), hemoglobin (12.25g/dl and 12.00g/dl), red blood cell (7.95 x106 / µl and 8.00 x106 / µl), white blood cell (8.12 x103 / µl and 7.91 x103 / µl) and lymphocyte counts (5.26 x103 / µl and 5.00 x103 / µl). Grower pigs on T6 recorded significantly (P <0.05) lower mean values for PCV (32.55%), hemoglobin concentration (Hb) (9.82g/dl), red blood cell (RBC) (5.32 x103 / µl), white blood cell (WBC) (6.10 x103 / µl), lymphocyte (3.10 x103 / µl) and monocyte (0.31 x103 / µl) counts, respectively. Based on the findings of this study, feeding of growing pigs with low energy and low crude protein diets below 16 % CP with multi-enzyme supplementation adversely effected PCV, hemoglobin, RBC, WBC, lymphocytes and monocytes of grower pigs and therefore should be avoided in pig production.

Full textAbstract:
Medical devices, which enhance the quality of life, have experienced a gradual increase in demand. Various research groups have attempted to incorporate soft materials such as skin into wearable devices. We developed a stretchable substrate with high elasticity by forming a porous structure on polydimethylsiloxane (PDMS). To optimize the porous structure, we propose a manufacturing process that utilizes a high-pressure steam with different viscosities (400, 800, 2100, and 3000 cP) of an uncured PDMS solution. The proposed method simplifies the manufacturing of porous structures and is cost-effective compared to other technologies. Porous structures of various viscosities were formed, and their electrical and mechanical properties evaluated. Porous PDMS (3000 cP) was formed in a sponge-like three-dimensional porous structure, compared to PDMS formed by other viscosities. The elongation of porous PDMS (3000 cP) was increased by up to 30%, and the relative resistance changed to less than 1000 times with the maximum strain test. The relative resistance increased the initial resistance (R0) by approximately 10 times during the 1500-times repeated cycling tests with 30% strain. As a result, patch-type wearable devices based on soft materials can provide an innovative platform that can connect with the human skin for robotics applications and for continuous health monitoring.

Abstract. Many ecosystem processes that influence Earth system feedbacks – vegetation growth, water and nutrient cycling, disturbance regimes – are strongly influenced by multidecadal- to millennial-scale climate variations that cannot be directly observed. Paleoclimate records provide information about these variations, forming the basis of our understanding and modeling of them. Fossil pollen records are abundant in the NE US, but cannot simultaneously provide information about paleoclimate and past vegetation in a modeling context because this leads to circular logic. If pollen data are used to constrain past vegetation changes, then the remaining paleoclimate archives in the northeastern US (NE US) are quite limited. Nonetheless, a growing number of diverse reconstructions have been developed but have not yet been examined together. Here we conduct a systematic review, assessment, and comparison of paleotemperature and paleohydrological proxies from the NE US for the last 3000 years. Regional temperature reconstructions (primarily summer) show a long-term cooling trend (1000 BCE–1700 CE) consistent with hemispheric-scale reconstructions, while hydroclimate data show gradually wetter conditions through the present day. Multiple proxies suggest that a prolonged, widespread drought occurred between 550 and 750 CE. Dry conditions are also evident during the Medieval Climate Anomaly, which was warmer and drier than the Little Ice Age and drier than today. There is some evidence for an acceleration of the longer-term wetting trend in the NE US during the past century; coupled with an abrupt shift from decreasing to increasing temperatures in the past century, these changes could have wide-ranging implications for species distributions, ecosystem dynamics, and extreme weather events. More work is needed to gather paleoclimate data in the NE US to make inter-proxy comparisons and to improve estimates of uncertainty in reconstructions.

4126 Background: GIDEON is a prospective, non-interventional study. Completion of GIDEON creates a large, global database of >3000 Sor-treated unresectable HCC (uHCC) pts, allowing for evaluation of a broad pt population, including Child-Pugh (CP) B pts with more advanced liver dysfunction. Methods: Baseline characteristics were collected in pts for whom a decision to treat with Sor had been made in clinical practice. Adverse events (AEs), dosing, and outcomes data were collected during follow-up. Results: 3,202 pts were evaluable for safety. Overall, the incidence of AEs and drug-related (DR) AEs was similar across CP subgroups, although serious AEs (SAEs) were more common in CP-B than CP-A pts. The rate of DR AEs (event per patient-year) was also comparable between CP-A and CP-B pts. The average daily Sor dose was slightly higher in CP-B than CP-A pts; duration of treatment was longer in CP-A (Table). In the intent-to-treat population (n=3,213), median overall survival (OS) (months [95% CI]) was longer in CP-A (13.6 [12.8-14.7]) than CP-B pts (5.2 [4.6-6.3]); time to progression was similar: CP-A (4.7 [4.3-5.2]); CP-B (4.4 [3.5-5.5]). Median OS was shorter in pts with a higher CP-B score: 7 (6.2 [4.9-8.7]); 8 (4.8 [4.1-6.9]); 9 (3.7 [3.0-5.1]). Conclusions: Sor safety and dosing during treatment are generally consistent across pts irrespective of liver function. As anticipated, CP status is a strong prognostic factor for OS in uHCC pts.

Abstract. The “4.2 ka event” is frequently described as a major global climate anomaly between 4.2 and 3.9 ka, which defines the beginning of the current Meghalayan age in the Holocene epoch. The “event” has been disproportionately reported from proxy records from the Northern Hemisphere, but its climatic manifestation remains much less clear in the Southern Hemisphere. Here, we present highly resolved and chronologically well-constrained speleothem oxygen and carbon isotopes records between ∼6 and 3 ka from Rodrigues Island in the southwestern subtropical Indian Ocean, located ∼600 km east of Mauritius. Our records show that the 4.2 ka event did not manifest itself as a period of major climate change at Rodrigues Island in the context of our record's length. Instead, we find evidence for a multi-centennial drought that occurred near-continuously between 3.9 and 3.5 ka and temporally coincided with climate change throughout the Southern Hemisphere.

Abstract. Three marine sediment cores distributed along the Norwegian (MD95-2011), Barents Sea (JM09-KA11-GC), and Svalbard (HH11-134-BC) continental margins have been investigated in order to reconstruct changes in the poleward flow of Atlantic waters (AW) and in the nature of upper surface water masses within the eastern Nordic Seas over the last 3000 yr. These reconstructions are based on a limited set of coccolith proxies: the abundance ratio between Emiliania huxleyi and Coccolithus pelagicus, an index of Atlantic vs. Polar/Arctic surface water masses; and Gephyrocapsa muellerae, a drifted coccolith species from the temperate North Atlantic, whose abundance changes are related to variations in the strength of the North Atlantic Current. The entire investigated area, from 66 to 77° N, was affected by an overall increase in AW flow from 3000 cal yr BP (before present) to the present. The long-term modulation of westerlies' strength and location, which are essentially driven by the dominant mode of the North Atlantic Oscillation (NAO), is thought to explain the observed dynamics of poleward AW flow. The same mechanism also reconciles the recorded opposite zonal shifts in the location of the Arctic front between the area off western Norway and the western Barents Sea–eastern Fram Strait region. The Little Ice Age (LIA) was governed by deteriorating conditions, with Arctic/Polar waters dominating in the surface off western Svalbard and western Barents Sea, possibly associated with both severe sea ice conditions and a strongly reduced AW strength. A sudden short pulse of resumed high WSC (West Spitsbergen Current) flow interrupted this cold spell in eastern Fram Strait from 330 to 410 cal yr BP. Our dataset not only confirms the high amplitude warming of surface waters at the turn of the 19th century off western Svalbard, it also shows that such a warming was primarily induced by an excess flow of AW which stands as unprecedented over the last 3000 yr.

Abstract. Presented here is the first chironomid calibration data set for tropical South America. Surface sediments were collected from 59 lakes across Bolivia (15 lakes), Peru (32 lakes), and Ecuador (12 lakes) between 2004 and 2013 over an altitudinal gradient from 150 m above sea level (a.s.l) to 4655 m a.s.l, between 0–17° S and 64–78° W. The study sites cover a mean annual temperature (MAT) gradient of 25 °C. In total, 55 chironomid taxa were identified in the 59 calibration data set lakes. When used as a single explanatory variable, MAT explains 12.9 % of the variance (λ1/λ2 = 1.431). Two inference models were developed using weighted averaging (WA) and Bayesian methods. The best-performing model using conventional statistical methods was a WA (inverse) model (R2jack = 0.890; RMSEPjack = 2.404 °C, RMSEP – root mean squared error of prediction; mean biasjack = −0.017 °C; max biasjack = 4.665 °C). The Bayesian method produced a model with R2jack = 0.909, RMSEPjack = 2.373 °C, mean biasjack = 0.598 °C, and max biasjack = 3.158 °C. Both models were used to infer past temperatures from a ca. 3000-year record from the tropical Andes of Ecuador, Laguna Pindo. Inferred temperatures fluctuated around modern-day conditions but showed significant departures at certain intervals (ca. 1600 cal yr BP; ca. 3000–2500 cal yr BP). Both methods (WA and Bayesian) showed similar patterns of temperature variability; however, the magnitude of fluctuations differed. In general the WA method was more variable and often underestimated Holocene temperatures (by ca. −7 ± 2.5 °C relative to the modern period). The Bayesian method provided temperature anomaly estimates for cool periods that lay within the expected range of the Holocene (ca. −3 ± 3.4 °C). The error associated with both reconstructions is consistent with a constant temperature of 20 °C for the past 3000 years. We would caution, however, against an over-interpretation at this stage. The reconstruction can only currently be deemed qualitative and requires more research before quantitative estimates can be generated with confidence. Increasing the number, and spread, of lakes in the calibration data set would enable the detection of smaller climate signals.

Full textAbstract:
Teil 1 dieser Dissertationsschrift fasst die Person-Situation Debatte zusammen und definiert stabile Persönlichkeitsmerkmale (Traits) sowie deren temporäre Expressionen (States). Zentrales Element der sogenannten Person-Situation Debatte war unter anderem das Konsistenzproblem, welches in der ersten empirischen Studie weiter beleuchtet wurde. Hierzu unterschieden wir Person- und Situation-Effekte auf Verhalten. Um diese Effekte zu differenzieren schlugen wir die Konzepte simple Konsistenz und residuale Konsistenz vor und zeigten, wie Verhalten in funktional äquivalenten Situationen auch nach Kontrolle des Einflusses von Persönlichkeit konsistent ist.
Teil 2 befasst sich dann mit der Definition und Erfassung von Situationen, da diese zentral sind um Konsistenz im Verhalten zu untersuchen. Im Rahmen von zwei Buchkapiteln beschrieben wir die bisherige Entwicklung der Situationsforschung und zeigten Herausforderungen auf, welche während der Entwicklung von Situationsmaßen zu meistern sind. Anschließend stellten wir sowohl eine neue Taxonomie zur Beschreibung von Situationen vor, die Situation Five, als auch ein Messinstrument zur Erfassung von Situationswahrnehmung vor.
Teil 3 adressiert die Validierung bestehender Situationsmaße und im Besonderen die mögliche Überschneidung von Situationswahrnehmung und Affekt. In zwei Studien wurde untersucht, ob beide Phänomene überlappen und dennoch jeweils Verhalten vorhersagen können. Hierbei konnten wir zeigen, dass dies nicht nur der Fall ist, sondern dass spezifische Verbindungen zwischen Verhalten und Situationswahrnehmung erst nach Berücksichtigung von Affekt sichtbar waren.
Teil 4 diskutiert die Implikationen der vorliegenden Arbeit und zeigt auf, wie insbesondere die Überlappung von Affekt und Situationswahrnehmung durch Einschätzungs-Theorien der Emotionsforschung erklärt werden können.
Teil 5 schlussendlich gibt einen Ausblick auf zukünftige Forschung und zeigt die Bedeutung der vorliegen Arbeit auf.Part 1 of the current work briefly reviews the person-situation debate and addresses the definition of personality traits and states. Central to the person situation debate was the definition of consistency. In the first empirical study presented here, we examined consistency in more detail. We introduced the concepts of simple and residual consistency, and showed how functionally equivalent situations may influence behavior, even after controlling for effects of personality. Part 2 is concerned with the definition and measurement of situations. In two book chapters, we reviewed the past development of situation research and specific challenges that can be faced during the construction of measures for situation dimensions. We then present a new taxonomy for the description of situations, the Situation Five, as well as a measurement tool to assess situation perception, a person’s interpretation and perception of situations. Part 3 addresses the validation of existing situation measures and, more specifically, the potential overlap of affect and situation perception. I the first empirical study, we examined this overlap, which turned out to be substantial. In the second study, we investigated if this overlap threatened the validity of situation measures: Would measures of situation perception predict behavior in daily life after controlling for affect? As it turned out, they did – and more importantly, controlling for affect unveiled specific, logically coherent links between situation perception and behavior. Part 4 then discusses implications of the current work. A special focus is placed on explaining why affect and situation perception were correlated and yet contributed uniquely to the explanation of variance in behavior. To summarize, appraisal theories of emotion may serve well as a general framework for understanding the processes involved in situation perception. Part 5 then briefly discusses implications of the current work for future research.

Full textAbstract:
Visuell-räumliche Aufmerksamkeit spielt eine Schlüsselrolle in der Wortverarbeitung und der Augenbewegungskontrolle beim Lesen. Dennoch bleibt die räumliche und zeitliche Dynamik von Aufmerksamkeitsbereitstellung innerhalb einer Fixation ungeklärt. Die vorliegende Dissertation nutzt drei Ansätze in der Ko-Registrierung von Augenbewegungen und EEG um diese Forschungslücke zu untersuchen und direkte Einblicke in die Aufmerksamkeitsverteilung zwischen Fovea und Parafovea, ihre Anpassung an Verarbeitungsansprüche und Sakkaden sowie ihre Auswirkungen auf Wortverarbeitung zu liefern. In Studie 1 wurde das Probe Paradigma als Maß zur Abbildung räumlicher Aufmerksamkeit ohne Augenbewegungen implementiert. Die vergrößerte, Probe-bezogene N1 zwischen Wortpräsentationen deutet auf eine Bereitstellung und Umverteilung zusätzlicher Ressourcen zur simultanen fovealen und parafovealen Wortverarbeitung hin. Studie 2 untersuchte den Preview Benefit und seine Modulation durch Sakkaden und Verarbeitungsschwierigkeit und zielte darauf ab, das elektrophysiologische Korrelat als indirektes Maß für parafoveale Aufmerksamkeit in ERPs und FRPs zu etablieren. Es zeigte sich ein Effekt des orthographischen Previews auf die N1. Interaktionen mit Lesemodus und Verarbeitungsschwierigkeit implizieren, dass dem Preview Effekt Aufmerksamkeitseffekte zugrunde liegen. In Studie 3 wurden zwei Datensätze hinsichtlich der Lateralisierung von Oszillationen im Alpha-Band untersucht um die in Studie 2 generierten Hypothesen zu unterstützen. Alpha war im sakkadischen Lesen stärker rechts-lateralisiert als in RSVP und eine stärkere Lateralisierung sagte eine kürzere Fixationsdauer vorher, was die Rolle von parafovealer Aufmerksamkeit und ihre Verbindung zu Sakkaden betont. Trotz der Einschränkungen der drei Ansätze stellt die Kombination von Augenbewegungen, ERPs, FRPs und EEG-Oszillationen geeignete Maße für Aufmerksamkeitsprozesse in der Wortverarbeitung dar, die traditionelle Forschungsmethoden ergänzen.Visuo-spatial attention is a key contributor to word processing and oculomotor control in reading. Yet, the spatial and temporal dynamics of attention allocation within a fixation remain unclear. The present dissertation uses three approaches in the co-registration of eye movements and EEG to investigate this gap and provide direct, online insights into attention distribution across fovea and parafovea, its adaptation to processing load and saccadic behavior, as well as its effects on word processing. In Study 1, the probe paradigm was implemented as a mapping tool of spatial attention adaptation in the absence of eye movements, yielding ERPs. The enhanced probe-related N1 in-between trials indicates a recruitment and redistribution of additional resources to achieve simultaneous foveal and parafoveal word-recognition. Study 2 tested the preview benefit and its modulation by saccades and foveal load, thereby aiming at establishing its electrophysiological correlate as an indirect index of parafoveal attention allocation in ERPs and FRPs. There was an effect of orthographic preview on the N1. Interactions with reading mode and foveal load indicate underlying attention effects. In Study 3, two datasets were reanalyzed with regard to the lateralization of oscillatory activity in the alpha-band in order to directly support the assumptions generated in Study 2. Alpha was more strongly right-lateralized in saccadic reading compared to RSVP, and moment-to-moment lateralization predicted shorter subsequent fixation duration, emphasizing the role of parafoveal attention allocation and its relation to saccades. Despite the limitations of the three approaches at this point, the combination of eye movements, ERPs, FRPs, and EEG oscillations provides suitable online markers of attention processes in word recognition that complement traditional research methods.

Full textAbstract:
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:
Aktuelle Affektforschung betont die Bedeutung mikrolängsschnittlicher Daten für das Verstehen täglichen affektiven Funktionierens, da sie es erlauben affektive Dynamiken und potentiell zugrunde liegende Prozesse zu beschreiben. Dynamische Längsschnittmodelle werden entsprechend attraktiver. In dieser Dissertation komme ich Forderungen nach einer Integration kontextueller Informationen in die Untersuchung täglichen affektiven Funktionierens nach. Speziell modifiziere ich populäre dynamische Modelle so, dass sie kontextuelle Variationen einbeziehen. In einem ersten Beitrag werden Personen als in Kontexte eingebettet begriffen. Der vorgeschlagene Ansatz der festen moderierten Zeitreihenanalyse berücksichtigt systemische Reaktionen auf kontextuelle Veränderungen, indem Veränderungen in allen Parametern eines dynamischen Zeitreihenmodells auf kontextuelle Veränderungen bedingt schätzt werden. Kontextuelle Veränderungen werden als bekannt und assoziierte Parameterveränderungen als deterministisch behandelt. Folglich sind Modellspezifikation und -schätzung erleichtert und in kleineren Stichproben praktikabel. Es sind allerdings Informationen über den Einfluss kontextueller Faktoren erforderlich. Anwendbar auf einzelne Personen erlaubt der Ansatz die uneingeschränkte Exploration interindividueller Unterschiede in kontextualisierten affektiven Dynamiken. In einem zweiten Beitrag werden Personen als mit Kontexten interagierend begriffen. Ich implementiere eine Prozessperspektive auf kontextuelle Schwankungen, die die Dynamiken täglicher Ereignisse über autoregressive Modelle mit Poisson Messfehler abbildet. Die Kombination von Poisson und Gaußscher autoregressiver Modellierung erlaubt eine Formalisierung des dynamischen Zusammenspiels kontextueller und affektiver Prozesse. Die Modelle sind hierarchisch aufgesetzt und erfassen so interindividuelle Unterschiede in intraindividuellen Dynamiken. Die Schätzung erfolgt über simulationsbasierte Verfahren der Bayesschen Statistik.Recent affect research stresses the importance of micro-longitudinal data for understanding daily affective functioning, as they allow describing affective dynamics and potentially underlying processes. Accordingly, dynamic longitudinal models get increasingly promoted. In this dissertation, I address calls for an integration of contextual information into the study of daily affective functioning. Specifically, I modify popular dynamic models so that they incorporate contextual changes. In a first contribution, individuals are characterized as embedded in contexts. The proposed approach of fixed moderated time series analysis accounts for systemic reactions to contextual changes by estimating change in all parameters of a dynamic time series model conditional on contextual changes. It thus treats contextual changes as known and related parameter changes as deterministic. Consequently, model specification and estimation are facilitated and feasible in smaller samples, but information on which and how contextual factors matter is required. Applicable to single individuals, the approach permits an unconstrained exploration of inter-individual differences in contextualized affective dynamics. In a second contribution, individuals are characterized as interacting reciprocally with contexts. Implementing a process perspective on contextual changes, I model the dynamics of daily events using autoregressive models with Poisson measurement error. Combining Poisson and Gaussian autoregressive models can formalize the dynamic interplay between contextual and affective processes. It thereby distinguishes not only unique from joint dynamics, but also affective reactivity from situation selection, evocation, or anticipation. The models are set up as hierarchical to capture inter-individual differences in intra-individual dynamics. Estimation is carried out via simulation-based techniques in the Bayesian framework.

Full textAbstract:
Die Psychologie der Lebensspanne und die Soziologie des Lebensverlaufs betonen die Bedeutung von Kontexten für den Erwerb individueller Fähigkeiten und die Entwicklung im Leben. In Übereinstimmung mit diesen konzeptionellen Annahmen zeigen Studien, dass verschiedene Kontexte die Entwicklung individueller Bereiche beeinflussen. Jedoch ist wenig darüber bekannt, wie kontextuelle Faktoren in der zweiten Lebenshälfte Wohlbefinden formen und wie Wohlbefinden in diesen Lebensphasen von sich schnell verändernden Kontexten beeinflusst wird. In dieser Dissertation werden unter Anwendung des Ökosystemischen Ansatzes von Bronfenbrenner drei Kontexte unterschiedlicher Proximität untersucht, in die die Entwicklung des individuellen Wohlbefindens eingebettet ist. Als erster Kontext wird die vielfältige Ökologie des Lebens und Sterbens in den ehemaligen Regionen Ost- und Westdeutschland herangezogen, um herauszufinden wie dieses Makrosystem Wohlbefinden in den letzten Lebensjahren gestaltet. Als zweiter Kontext wird die Bedeutung des Exosystems von Gesundheitseinrichtungen in Landkreisen (z.B. Anzahl stationärer Pflegereinrichtungen) auf Wohlbefindensverläufe am Lebensende beleuchtet. Als dritten Kontext untersuchen wir, wie das Mikrosystem sozialer Ökologien und Situationen momentanes, affektives Wohlbefinden gestaltet, sowie Altersunterschiede in diesen Assoziationen. Gemeinsam zeigen die drei Studien dieser Dissertation, dass Ökologien auf regionaler, dienstleistender und sozialer Kontextebene Entwicklung von Wohlbefinden in der zweiten Lebenshälfte beeinflussen. Diese Arbeit zeigt, dass Kontexte sowohl kognitives als auch affektives Wohlbefinden und innerhalb des letzteren sowohl Valenz und Aktivierung beeinflussen, und untersucht länger- und kurzfristige Kontext-Wohlbefindens-Assoziationen in späteren Lebensphasen. Die Ergebnisse liefern erste Vorschläge für Interventionen und veränderbare regionale Faktoren für die Erhaltung oder Verbesserung von Wohlbefinden.Lifespan psychology and life course sociology have long acknowledged the role of context for individual functioning and development throughout life. Consistent with these conceptual notions, empirical studies show that various contextual factors influence development of individual-level outcomes. However, we know little about how contextual factors shape individual-level well-being and how well-being is influenced by fast changing contexts in the second half of life. Applying Bronfenbrenner’s model of human ecology as the overarching theoretical frame, this dissertation examines three sets of contexts that differ in the degree of proximity in which individual well-being and its development is embedded in. As a first context, the multifaceted ecology of living and dying in former regions of East and West Germany is used to investigate how the macrosystem shapes individual well-being in the last years of life. For a second context, the role of the exosystem of county-level health care features (e.g., number of inpatient care facilities) on late-life trajectories in well-being is examined. As a third context, we examine how the microsystem of social ecologies and situations influences momentary affective well-being and how these associations differ across age. Jointly, the three studies in this dissertation show that regional, service, and social ecologies profoundly shape development in well-being during the second half of life. To conclude, this dissertation shows that these contexts influence both cognitive and affective components of well-being, among the affective domain two facets (valence and arousal), and investigates long-term and short-term contextwell- being associations in later life phases. Results provide initial suggestions for interventions and malleable regional factors to maintain or improve well-being.

However, under conditions of extreme or chronic stress, the stress response can become maladaptive and can negatively impact the brain, behavior, and cognition. Combat exposure is a specific instantiation of prolonged stress, and one that is growing in relevance due to an increasing number and escalating intensity of military conflicts across the globe. In this dissertation, I investigate stress-related losses and recovery-related gains in gray matter volume, mainly in combat-exposed military populations. The present dissertation contributes to knowledge about the relationship between stress and the brain in four ways: (a) it investigates the relationship between stress exposure and the brain in subclinical populations, (b) it investigates potential functional mechanisms for the development and maintenance of combat-related posttraumatic stress disorder (PTSD), (c) it investigates alterations in grey matter volume following therapeutic interventions for combat-related PTSD, and (d) it investigates the neural correlates of symptom exaggeration in PTSD. The dissertation is publication-orientated and consists of six papers. At the time of submission, Paper I, Paper II, Paper III and Paper IV have been published. Paper V and Paper VI have been submitted and are currently under review.

Full textAbstract:
Die vorliegende Arbeit geht der Frage nach, wie Gutachterinnen und Gutachter im Rahmen von Gruppenbegutachtungen zu einer gemeinsamen Bewertungsentscheidung finden. Untersucht wird diese Frage am Beispiel von Gruppenbegutachtungen zur Förderung von Sonderforschungsbereichen (SFB). Die Ergebnisse der Arbeit zeigen, dass sowohl die organisatorischen Rahmenbedingungen der Begutachtungssitzungen als auch die Organisation des gesamten Peer-Review-Prozesses, in welchem die Gruppenbegutachtung in der Regel nur einen Verfahrensschritt darstellt, maßgeblichen Einfluss auf den Prozess der Entscheidungsfindung innerhalb des Panels nehmen, wie auch auf die letztendliche konsensuale Entscheidung der Gutachtergruppe und die (unerwünschten) Gruppenphänomene, die während der Panelbegutachtung auftreten können. Die Ergebnisse zeigen darüberhinaus, dass Gutachtende den Prozess der Begutachtung sowohl als Subjekt ihrer eigenen Entscheidungsfindung (Rolle: Gutachter) als auch als Objekt des Entscheidungsfindungsprozesses anderer (Rolle: Antragsteller) wahrnehmen. Deshalb ist es für sie zentral, als Subjekt an einem Prozess teilzunehmen, der so fair ist, dass sie ihn auch als Objekt der Entscheidung anderer als fair erleben können. Dieser persönlichen Forderung nach Fairness kommt die Gruppenbegutachtung, den Ergebnissen zu Folge, stärker entgegen als die Einzelbegutachtung. Methodisch wurde ein exploratives Vorgehen gewählt und drei SFB-Beratungsgespräche sowie vier SFB-Einrichtungsbegutachtungen mit Hilfe der Methode der nicht-teilnehmenden Beobachtung analysiert. Zusätzlich wurden 80 Leitfadeninterviews mit Beteiligten der Begutachtungssitzungen und ausgewählten Antragstellenden sowie Dokumentenanalysen von Begutachtungsunterlagen durchgeführt.The study addresses the question of how peer review committees come to a consensual decision. Therefore the decision making process of review committees to promote collaborative research centres (CRC, in German: Sonderforschungsbereiche, SFB) was analyzed. The results show that the organizational framework of the evaluation sessions as well as the organization of the entire peer review process (whereby the group evaluation is only one step in the whole process) have a great influence on: (1) on the decision making process within the panel, (2) on the final consensual decision of the panel group and (3) on the (unwanted) group phenomena that may occur during panel reviews. In addition the results illustrate that reviewers perceived the process of evaluations as both the subject of their own decisions (role: reviewer) as well as the object of the decision-making process of others (role: applicant). Therefore, for them it is central as a subject to participate in a process that is so fair that they can also experience the process as being wholly fair as an object of the decision of others. This personal call for fairness is stronger in relation to group evaluations than for individual peer review evaluations. Methodologically, an exploratory approach was chosen and three CRC preliminary review session (SFB Beratungsgespräch) and four CRC on-site reviews (SFB Einrichtungsbegutachtungen) were analyzed using the method of non-participant observation. In addition, 80 semi-structured interviews were conducted with evaluation session participants and selected applicants and a content analysis of review documents were done.

Full textAbstract:
Abstract In this study, a compressible low-Reynolds number flow over a circular cylinder was investigated by schlieren visualization and the force measurement. A Reynolds number based on freestream quantities and a diameter of a cylinder is set to be 1000 ≤ Re ≤ 5000 and a Mach number is set to be 0.1 ≤ M ≤ 0.5 by using the low-pressure wind tunnel. From the schlieren visualization, frequency of the vortex shedding was obtained by performing frequency analysis on the time series schlieren images. Near wake structure by the circular cylinder is measured by time-averaged schlieren image. Even though M is less than 0.5, the structure of the flow fields changes depending on M. The effect of M on the scale of wake structure depends on Re. Under the condition at Re of 1000–3000, the scale becomes large as M increases more than 0.2. On the other hand, under the condition that Re is 4000–5000, it becomes small as M increase 0.3 or more St is revealed to be decrease for Re of 2000–3000 with increasing M, and St increases at Re of 4000–5000. From the force measurement, drag coefficient (Cd) and pressure distribution on a circular cylinder (Cp) obtained. The effect of M on Cd does not depend on Re, and Cd also increases as M increases. The effect of Re on Cd is also observed that Cd increases as Re increases and this trend doesn’t depend on M. The Cp decrease with Re increase. The M effect on Cp is that the range of Cp is enlarged with M increase.

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:
In this work, a novel liquid bridge based microstereolithography (LBMSL) was proposed and developed. The liquid bridge was first introduced into the MSL process by replacing the vat, allowing the entire fabrication process to occur within the liquid bridge. The liquid bridge was studied theoretically and experimentally in order to obtain the stable equilibrium shape and the relationship between the height and the volume of the liquid bridge. Using the LBMSL process, the fabrication layer thickness of 0.5 μm was reached. This could not be easily achieved in the vat-based MSL due to the oxygen inhibition to the photopolymer. Fabrication of a photopolymer with a viscosity of 3000 cP was tested and significant results were obtained. Compared with the vat-based MSL, the material consumption in LBMSL was reduced and the fabrication time was improved greatly, in particular, when using higher viscous materials.

Abstract Individuals with foot drop caused by stroke or cerebral palsy (CP) have a particular need for robotic ankle exoskeleton. This paper proposes an untethered soft robot using an origami actuator to lift the toes of the wearer. The weight, connections, and complex control of the system are reduced through mechanical design. A compact and portable pneumatic system is designed to perform suction and compression with a single pump. The load test of the actuator shows the capability of 300N in 30 kPa. An untethered, simple and affordable robotic ankle exoskeleton is developed with the pneumatic actuator. The wearer can finish its simple 3-step donning procedure within 1 min.

Full textAbstract:
In this paper, we examine, computationally, a uniform flow past a rotating circular cylinder. The objective is to determine the effect the rotation has on the lift and drag acting on the cylinder, on the vortex structures and on the vortex-shedding frequency. A streakline calculation illustrates the effect the rotation has on the vortex-structure in the wake. A combination of finite-difference and spectral methods is used to calculate the three-dimensional incompressible unsteady Navier-Stokes equations in primitive variable form in nonorthogonal curvilinear coordinates. A second-order accurate in time fractional-step method is used to decouple pressure and velocity components. High-order compact-difference schemes are used to avoid the problem of the so-called checker-board behavior. The calculated lift coefficient (CL), drag coefficient (CD) and pressure coefficient (CP) of the flows at a Reynolds number of 200 and α = 1 to 5 (α is the nondimensional ratio of the rotating speed-to-free stream speed) agreed very well with results in the literature. However, streak line patterns were not presented in these earlier studies. We also have drag and lift results at Re = 1000 for the same range of α values. These results are found to follow the same trends as at Re = 200. These results have a practical application in offshore drilling.
