Do H and O in leaf water reflect environmental drivers differently?

We compiled hydrogen and oxygen stable isotope compositions (δ H and δ O) of leaf water from multiple biomes to examine variations with environmental drivers. Leaf water δ H was more closely correlated with δ H of xylem water or atmospheric vapour, whereas leaf water δ O was more closely correlated with air relative humidity. This resulted from the larger proportional range for δ H of meteoric waters relative to the extent of leaf water evaporative enrichment compared with δ O.

The cholinergic anti-inflammatory pathway in humans: State-of-the-art review and future directions.

The parasympathetic nervous system modulates inflammation through efferent vagus nerve signaling. Tracey (2002) termed this process as the cholinergic anti-inflammatory pathway (CAP). Interest in the potential practical use of this immune-modulatory process is increasing alongside increasing appreciation for the role of systemic inflammation in the etiology of somatic and psychological disease.

Looking into the black box of "Medical Innovation": rising health expenditures by illness type.

There is agreement among health economists that on the whole medical innovation causes health care expenditures (HCE) to rise. This paper analyzes for which diagnoses HCE per patient have grown significantly faster than average HCE. We distinguish decedents (patients in their last 4 years of life) from survivors and use a unique dataset comprising detailed HCE of all members of a regional health insurance fund in Upper Austria for the period 2005-2018.

Stressed in afterthought: Neuroendocrine effects of social self-threat during physical effort are counteracted by performance feedback after stress exposure.

Social self-threat during physical stress, such as exposure to the cold pressor test and isometric handgrip test, has been shown to induce activation of the HPA axis, in addition to autonomic responses. However, previous research has suggested that dysfunctional post-event processing may play a major role in neuroendocrine reactivity at initial as well as subsequent social stress exposure. In the present study, we investigated how the interplay of context (i.

"[Culture] Makes Each Country Unique, It's Kind of like a Trademark." Empirical Results on Students' Perceptions of Culture and Space as Learning Prerequisite for Geography Lessons.

Students' everyday perceptions of culture and space have a significant impact on their social coexistence and should, therefore, be considered in geography lessons. The or is often negatively assessed. This perception is based on an essentialist understanding of cultural space but is inappropriate for a culturally diverse world.

On the role of item encoding mechanisms in associative memory in young and older adults: A mass univariate ERP study.

We examined the role of item encoding mechanisms in older adults' disproportionate deficit in memory for associations and individual differences therein. Young and older adults encoded sequentially presented object pairs via interactive imagery while their EEG was recorded. Compared to the young adults, older adults exhibited a reduction in associative, but not in item memory performance.

Central Mongolian lake sediments reveal new insights on climate change and equestrian empires in the Eastern Steppes.

The repeated expansion of East Asian steppe cultures was a key driver of Eurasian history, forging new social, economic, and biological links across the continent. Climate has been suggested as important driver of these poorly understood cultural expansions, but paleoclimate records from the Mongolian Plateau often suffer from poor age control or ambiguous proxy interpretation. Here, we use a combination of geochemical analyses and comprehensive radiocarbon dating to establish the first robust and detailed record of paleohydrological conditions for Lake Telmen, Mongolia, covering the past ~ 4000 years.

Predicting patients who will drop out of out-patient psychotherapy using machine learning algorithms.

Background: About 30% of patients drop out of cognitive-behavioural therapy (CBT), which has implications for psychiatric and psychological treatment. Findings concerning drop out remain heterogeneous.

Aims: This paper aims to compare different machine-learning algorithms using nested cross-validation, evaluate their benefit in naturalistic settings, and identify the best model as well as the most important variables.

How to choose the size of facial areas of interest in interactive eye tracking.

Advances in eye tracking technology have enabled the development of interactive experimental setups to study social attention. Since these setups differ substantially from the eye tracker manufacturer's test conditions, validation is essential with regard to the quality of gaze data and other factors potentially threatening the validity of this signal. In this study, we evaluated the impact of accuracy and areas of interest (AOIs) size on the classification of simulated gaze (fixation) data.

Proneness to psychotic-like experiences as a basic personality trait complementing the HEXACO model-A preregistered cross-national study.

The goal of the study is to investigate the relationship between the HEXACO personality model and Disintegration-representing a broad spectrum of psychotic-like experiences and behavioral tendencies (Perceptual Distortions, General Executive/Cognitive Impairment, Enhanced Awareness, Paranoia, Mania, Flattened Affect, Apathy/Depression, Somatoform Dysregulation, and Magical Thinking) that are reconceptualized as a personality trait. In this preregistered study, we predicted that the Disintegration factor would separate from HEXACO. The replicability of the factorial structures of HEXACO and Disintegration subcomponents is investigated across the three national samples (UK, Germany, and Serbia), matched on key socio-demographic variables.

Same, but different: Binding effects in auditory, but not visual detection performance.

Responding to a stimulus leads to the integration of response and stimulus' features into an event file. Upon repetition of any of its features, the previous event file is retrieved, thereby affecting ongoing performance. Such integration-retrieval explanations exist for a number of sequential tasks (that measure these processes as 'binding effects') and are thought to underlie all actions.

No transfer effect of a fraction number line game on fraction understanding or fraction arithmetic: A randomized controlled trial.

Fractions are hard to understand for students. According to Siegler's integrated theory, magnitude understanding is central to numerical development. Whole-number magnitude understanding can be improved by serious games that include practicing mapping numbers onto number lines or similar one-dimensional visuospatial representations.

No perfect sleep! A systematic review of the link between multidimensional perfectionism and sleep disturbance.

The view that perfectionists are prone to experiencing sleep disturbance is widely held. Yet, almost three decades of empirical research have yielded conflicting results. Whereas some researchers viewed perfectionism as a risk factor for sleep disturbance, others spoke of "adaptive" or "positive" forms of perfectionism in the context of sleep.

Potential risk groups and psychological, psychosocial, and health behavioral predictors of pharmacological neuroenhancement among university students in Germany.

Aiming to develop and implement intervention strategies targeting pharmacological neuroenhancement (PN) among university students more specifically, we (1) assessed the prevalence of PN among German university students, (2) identified potential sociodemographic and study-related risk groups, and (3) investigated sociodemographic, psychological, study-related psychosocial, general psychosocial and health behavior related factors predicting the 12-month prevalence of PN. Therefore, a cross-sectional online survey was administered to students of the University of Mainz, Germany. A binary logistic regression with stepwise inclusion of the five variable groups was performed to predict PN.

COVID-19 and the -how does the overseas Chinese community react to group criticism?

We conduct an online survey to explore how Chinese people living in Germany perceive and react to group criticism in the context of the debate on the , a chronicle about life during the lockdown in Wuhan. We find that the majority rating of the book is a lukewarm "neither like nor dislike." Most participants are open to criticism in principle and do not agree that the book only spreads so-called "negative-energy".

Temporal stability and change in manifest intelligence scores: Four complementary analytic approaches.

The temporal stability of psychological test scores is one prerequisite for their practical usability. This is especially true for intelligence test scores. In educational contexts, high stakes decisions with long-term consequences, such as placement in special education programs, are often based on intelligence test results.

Psychopathological networks: Theory, methods and practice.

In recent years, network approaches to psychopathology have sparked much debate and have had a significant impact on how mental disorders are perceived in the field of clinical psychology. However, there are many important challenges in moving from theory to empirical research and clinical practice and vice versa. Therefore, in this article, we bring together different points of view on psychological networks by methodologists and clinicians to give a critical overview on these challenges, and to present an agenda for addressing these challenges.

Breaking the anxious cycle of self-criticism: Action orientation buffers the detrimental effects of a self-critical personality style.

Background: A self-critical personality style has been associated with psychological symptoms such as depression and anxiety. Self-critical people also tend to strive more anxiously for basic motives such as affiliation, achievement, power, and autonomy. This anxious motive enactment mediates the relationship between self-critical style and psychological symptoms that may, in turn, reinforce self-criticism.

Conspiracy theories on Twitter: emerging motifs and temporal dynamics during the COVID-19 pandemic.

Unlabelled: The COVID-19 pandemic resulted in an upsurge in the spread of diverse conspiracy theories (CTs) with real-life impact. However, the dynamics of user engagement remain under-researched. In the present study, we leverage Twitter data across 11 months in 2020 from the timelines of 109 CT posters and a comparison group (non-CT group) of equal size.

Clients' Emotional Experiences Tied to Therapist-Led (but Not Client-Led) Physiological Synchrony during Imagery Rescripting.

Imagery rescripting (IR), an effective intervention technique, may achieve its benefits through various change mechanisms. Previous work has indicated that client-therapist physiological synchrony during IR may serve as one such mechanism. The present work explores the possibility that therapist-led vs.

Remote Testing of the Familiar Word Effect With Non-dialectal and Dialectal German-Learning 1-2-Year-Olds.

Variability is pervasive in spoken language, in particular if one is exposed to two varieties of the same language (e.g., the standard variety and a dialect).

Associations Between Fathers' Masculinity Orientation and Anticipated Reaction Toward Their Child's Coming Out.

The present study examined associations between fathers' masculinity orientation and their anticipated reaction toward their child's coming out as lesbian or gay (LG). Participants were 134 German fathers (28 to 60years) of a minor child. They were asked how they would personally react if, one day, their child disclosed their LG identity to them.

Goal-Based Binding of Irrelevant Stimulus Features for Action Slips.

Binding between representations of stimuli and actions and later retrieval of these compounds provide efficient shortcuts in action control. Recent observations indicate that these mechanisms are not only effective when action episodes go as planned, but they also seem to be at play when actions go awry. Moreover, the human cognitive system even corrects traces of error commission on the fly because it binds the intended but not actually executed response to concurrent task-relevant stimuli, thus enabling retrieval of a correct, but not actually executed response when encountering the stimulus again.

Measurement-Based and Data-Informed Psychological Therapy.

Outcome measurement in the field of psychotherapy has developed considerably in the last decade. This review discusses key issues related to outcome measurement, modeling, and implementation of data-informed and measurement-based psychological therapy. First, an overview is provided, covering the rationale of outcome measurement by acknowledging some of the limitations of clinical judgment.

Non-destructive investigation of extracellular enzyme activities and kinetics in intact freshwater biofilms with mineral beads as carriers.

Current procedures for fluorometric detection of extracellular hydrolytic enzyme activities in intact aquatic biofilms are very laborious and insufficiently standardized. To facilitate the direct determination of a multitude of enzymatic parameters without biofilm disintegration, a new approach was followed. Beads made of different mineral materials were subjected to biofilm growth in various aquatic environments.
