Changes In Personality Functioning Following The End Of Psychotherapy [data]
No full textAbstract of the Study:
Introduction: Although personality functioning has a long psychodynamic tradition and has received renewed interest in psychotherapy research with the DSM-5 and ICD-11, almost nothing is known about its course and influencing factors following psychotherapy.
Methods: In a sample of 1208 completed psychotherapies from the Heidelberg Institute for Psychotherapy, we examined changes in personality functioning in the 1-year follow-up. We then used machine learning to filter out the probable predictors from all 277 possible predictors for changes in personality functioning following psychotherapy.
Results: On average, the improvement in personality functioning remained stable following psychotherapy. However, it was found that patients whose personality functioning worsened during psychotherapy improved again following psychotherapy. Patients who improved particularly well during psychotherapy worsened slightly following psychotherapy. In total, we found 14 predictors for improved personality functioning following psychotherapy.
Discussion: All the influences found suggest that the change in psychotherapy is in part influenced by how well the patient succeeds in internalising the insights gained in psychotherapy or the therapist. If this does not succeed, the patient cannot compensate for the loss of co-regulation by the therapist at the end of therapy and some of the improvements in psychotherapy are lost. For example, we found that with fewer than 20 hours of psychotherapy, it must be assumed that the patient will worsen in personality functioning following psychotherapy. From 20 hours onwards, the improvement remains stable and from 95 hours onwards, a subsequent improvement can be expected.

An Overview of: Prosopographic Digital Data in Classics (Persons and Names)
No full textThe here offered compilation forms the basis for an article within the Brill’s Companion to Roman Prosopography (Horster, M., Hurlet, F., Fower, R., Mathisen, R. edd., forthcoming 2025), on the topic of “Data Repositories and Sustainability: Their Significance for Prospographical Data Archives” by Feraudi-Gruénais, F. and Grieshaber, F.
There is only a comparatively modest number of online-accessible digital collections concerning personal names from the ancient world, especially if we consider only the segment that concerns Roman names. Yet a detailed comparison of the databases, projects, portals and tools for this topic presents a very heterogeneous picture, making it difficult at first glance to gain an overview and so to evaluate their usefulness as a whole.
As always, the reasons for this are complex and arise primarily from the different historical genesis of the data collections, but also from the variety of ways they are designed in terms of content, and the different kinds of ancient sources on which they are based. Other issues are the non-homogeneous origin and creation of the digital data (were they born digital or not?), the often thoroughly non-uniform project goals (genuinely prosopographic or not? relating more to persons or more to names?) and the variety of focuses chosen in date, geography or cultural regions; and also the degrees of digital depth pursued in metadata, inconsistency in including normed and/or controlled vocabularies and the selectively implemented allocation of unique person-IDs. Finally, a factor not to be underestimated is that time and funding for projects are usually limited, with effects on the afterlife of the data (is it active, paused, completed?).
The here presented compilation therefore pursues two goals: It aims firstly to review the variety, characteristics and differences of the digital data archives on persons or personal names in the Roman empire that are currently well known and accessible online, and secondly to visualize at a glance the existing potentials and the needs for optimisation in the efforts made so far in the sphere of digital prosopographical data collections
4D Printing of thermoresponsive OEGMA-based hydrogels with tunable response [data]
No full textHydrogels, particularly those exhibiting responsive behaviors, have gained significant attention, especially with the advent of 4D printing. Among thermoresponsive hydrogels, poly(N-isopropylacrylamide) (PNIPAM)-based materials remain a benchmark for 4D microprinting featuring typical lower critical solution temperatures (LCSTs) ranging from 32 to 37 °C. However, precise tuning of the LCST to a broader temperature range is necessary to expand the application window. This study introduces thermoresponsive poly(oligo(ethylene glycol)methacrylate) (POEGMA)-based polymers as alternative printable materials for two-photon laser printing (2PLP). First, a library of prepolymers with LCSTs ranging from 33 to 66 °C is synthesized and characterized. By formulating these prepolymers with a suitable photoinitiator in water, inks compatible with 2PLP are created. The printing performance of each ink is evaluated by fabricating complex 4D microstructures, including various platonic solids exhibiting LCSTs ranging from 33 to 66 °C, surpassing the constraints of PNIPAM. The actuation performance of each material is evaluated quantitatively by monitoring volume changes at different temperatures. Finally, arrays of “twistable” tetrahedrons are fabricated in multi-material fashion, showcasing temperature selective actuation. Thus, we demonstrate that the careful design of the macromolecular architecture offers precise LCST adjustment in final printed microstructures, a feature highly beneficial for applications like soft microrobotics among others
Ligand-Induced Crystallization Control in MAPbBr3 Hybrid Perovskites for High Quality Nanostructured Films [Research Data]
No full textControlling the formation of hybrid perovskite thin films is crucial in obtaining high-performance optoelectronic devices, since factors like morphology and film thickness have a profound impact on a film’s functionality. For light-emitting applications grain sizes in the sub-micrometer-range have previously shown enhanced brightness. It is therefore crucial to develop simple, yet reliable methods to produce such films. Here, a solution-based synthesis protocol for the on-substrate formation of MAPbBr3 (MA = methylammonium) nanostructures by adding the bifunctional rac-3-aminobutyric acid to the precursor solution is reported. This synthesis route improves key optical properties such as photoluminescence quantum yields and life times of excited states by inducing a controlled slow-down of the film formation and suppressing agglomeration effects. In-situ spectroscopy reveals a delayed and slowed down crystallization process, which achieves synthesis of perovskite structures with much reduced defect densities. Further, aggregation can be controlled by the amount of amino acid added and adjusting the synthesis protocol allows to produce cubic crystallites with targeted size from nanometer to micrometer scales. The nanocrystalline MAPbBr3 samples show enhanced amplified spontaneous emission (ASE) intensities, reduced ASE thresholds and purer ASE signals, compared to pristine films, even under intense optical driving, making them promising structures for lasing applications
Peptide Boronic Acids by Late-Stage Hydroboration on the Solid Phase [Research data]
No full textOrganoboron compounds have a wide range of applications in numerous research fields, and methods to incorporate them in biomolecules are much sought after. Here, on-resin chemical syntheses of aliphatic and vinylogous peptide boronic acids are presented by transition metal-catalyzed late-stage hydroboration of alkene and alkyne groups in peptides and peptoids, for example on allyl- and propargylglycine residues, using readily available chemicals. These methods yield peptide boronic acids with much shorter linkers than previously reported on-resin methods. Furthermore, the methods are regio- and stereoselective, compatible with all canonical amino acid residues and can be applied to short, long, and in part even “difficult” peptide sequences. In a feasibility study, the protected peptide vinylboronic acids are further derivatized by the Petasis reaction using salicylaldehyde derivatives. The ability of the obtained peptide boronic acids to reversibly bind to carbohydrates is demonstrated in a catch-release model experiment using a fluorescently labeled peptide boronic acid on cross-linked dextran beads. In summary, this highlights the potential of the target compounds for drug discovery, glycan-specific target recognition, controlled release, and diagnostics
Legislative bargaining with private information: Experimental evidence comparing unanimity and majority rule [Dataset]
No full textThis paper experimentally investigates behavior in a legislative bargaining game with private information. A single proposer is seeking to pass a proposal. In each of two rounds, she attempts to buy the necessary votes by offering payments. Between rounds, the game ends in breakdown with a certain probability. The two responders hold privately known disagreement values. We compare behavior under majority (one vote needed) vs. unanimity (both votes needed) rule. The main theoretical prediction is that responders are more ``expensive'' in round 1 under unanimity rule because there exists a signaling incentive to vote ``no''. Under majority rule, this incentive is absent and in fact, responders should fear being excluded after voting ``no''. Our experimental findings confirm the presence of signaling incentives under unanimity rule, resulting in lower agreement probabilities than under majority rule. In contrast, the experimental evidence under majority rule is mixed and does not fully coincide with the theoretical predictions
Usage of a German prevention and health promotion web portal and cost per pageview: a life-cycle assessment [research data and code]
No full textBackground: Web portals providing health information online have the potential to reach large numbers of people. Yet few studies have assessed usage and costs of health portals, especially over an extended period of time.
Objectives: First, to assess the usage of a web portal on prevention and health promotion that was initiated by the German states of Berlin and Brandenburg. Second, to estimate average cost per pageview over the full web portal life-cycle.
Methods: Usage data were gathered through Google Analytics. The main usage metric assessed was pageviews originating from an IP address in Berlin or Brandenburg. Project cost data were reported by the local government and from own records. Descriptive and regression analyses were used to determine time trends in pageviews.
Results: The redesigned web portal Praeventionsatlas.de launched August 2011 and was discontinued March 2018. Analyzing the full calendar years only, the annual pageview number increased from 2012 (8492) to its peak in 2014 (11,876) and steadily decreased to its minimum in 2017 (7232). Pages of the web portal were most often viewed around lunchtime (12 to 1 p.m.), in the middle of the week (Wed to Thu), and at the beginning of the year (Jan to Feb). Adjusting for year, month, and weekday, the number of daily pageviews dropped on major public holidays (Easter −9, Pentecost −12, Christmas −12 and New Year’s Eve and Day −20; P<.001) and increased during the fasting period before Easter (+6; P<.001). Average cost per page viewed from relaunch until the web portal went offline was estimated to be €0.38 (€0.33 to €1.67) per pageview.
Conclusion: Usage of the web portal showed temporal variation and peaked before the middle of its 6.5 year life-cycle. Development and need for updates may require substantial investment in a web portal, such that a pageview can come at a considerable expense, even in small-scale projects. Assessing and discussing the cost-effectiveness of a web portal is therefore desirable
Hormonal synchrony in older couples' everyday life [Research data and script]
No full textSynchrony in physiology in romantic couples has been suggested to be a result of joint interaction and co-regulation of stress and affect. However, it is subject of debate whether synchrony in endocrine levels - especially in oxytocin - is generally beneficial or if a reciprocal transmission of stress may even be stress-increasing. The aim of this study was to investigate hormonal synchrony in older couples in relation to situational mindfulness, relationship conflict (quarreling), as well as situational resilience and subjective stress levels. A total of N = 26 individuals (i.e., N = 13 couples) aged between 52 and 75 years provided saliva samples and self-report measures 12 times over the course of 2 days (312 measures in total). Superior to randomly scrambled dyads, multilevel models predicted cortisol, alpha-amylase, and oxytocin levels from one partner for the other. Synchrony was higher at times of high levels of quarreling but mitigated in moments of high mindfulness. Moreover, oxytocin synchrony was reduced in couples exerting higher average levels of stress. We interpret this finding as buffering personal factors to protect against the transmission of dyadic stress. To draw implications for clinical interventions to promote these factors and given the preliminary character of the sample and the effects, future studies need to systematically expand this field of research and application
