description: 13. P. Smithii Saussure 1853, P. defectivus Gerstäcker 1870. Es ist mir unmöglich, zwischen diesen beiden Arten einen Unterschied zu finden: ich halte sie daher für svnonym. Bei den meisten Individuen ist die innere Klaue ein klein bißchen größer als die äußere, wodurch diese Art den Übergang bildet von der Gruppe madecassus zur 2. Gruppe. Der Kopfschild des ♀ ist scheinbar deutlich breiter als lang: mit dem Mikrometer gemessen, ist die Breite gleich cler Länge inklusive Spitze: der Kopfschild des 5 ist um weniges breiter als lang, unten breiter als oben: der Unterrand bald gleichmäßig leicht gebogen, bald in der Mitte als abgerundete Spitze vortretend, bald auch ist diese Spitze in der Mitte leicht gebuchtet, und zwar zeigen sich diese Unterschiede bei Individuen, die ein und demselben Neste entstammen.

description: Peerbeziehungen spielen in der Entwicklung und Lebensgestaltung von Schülerinnen und Schülern eine zentrale Rolle. Peers orientieren sich bei schulischen Regelbrüchen in der Klasse an Schulnormen oder an informellen Gruppennormen, die für das Lernsetting und die öffentliche Wahrnehmung von Schule bedeutsam, aber zugleich schwer zugänglich sind. Deshalb untersucht die vorliegende Studie, in welchen Fällen und wie in Schulklassen, als eine Form einer organisierten Peergroup, Regelbrüche legitimiert oder verurteilt werden. Zu diesem Zweck sind Gruppendiskussionen mit 14- bis 15-Jährigen aus vier bezüglich sozialer Lage und Bevölkerungsdichte kontrastierenden Schulen an der Zürcher Volksschule geführt worden. Die Auswertung unter Anlehnung an die dokumentarische Methode verweist auf eine grundsätzliche Orientierung an Schulnormen. Jedoch kommen situativ abweichende und informelle Gruppennormen bei gleichzeitiger Anerkennung der Schulnormen vor. Erstere treten insbesondere bei fehlender oder ungenügender Aufsicht der Lehrperson und bei solidem Klassenzusammenhalt unter den Peers auf.

description: In the era of time-domain, multi-messenger astronomy, the detection of transient events on the high-energy electromagnetic sky has become more important than ever. Previous attempts to systematically search for onboard-untriggered events in the data of Fermi-GBM have been limited to short-duration signals with variability time scales smaller than ~1 min due to the dominance of background variations on longer timescales. In this study, we aim at the detection of slowly rising or long-duration transient events with high sensitivity and full coverage of the GBM spectrum. We make use of our earlier developed physical background model, propose a novel trigger algorithm with a fully automatic data analysis pipeline. The results from extensive simulations demonstrate that the developed trigger algorithm is sensitive down to sub-Crab intensities, and has a near-optimal detection performance. During a two month test run on real Fermi-GBM data, the pipeline detected more than 300 untriggered transient signals. For one of these transient detections we verify that it originated from a known astrophysical source, namely the Vela X-1 pulsar, showing pulsed emission for more than seven hours. More generally, this method enables a systematic search for weak and/or long-duration transients.

description: Amid recent progress in cognitive development research, high-quality data resources are accumulating, and data sharing and secondary data analysis is becoming an increasingly valuable tool. Integrative data analysis (IDA) is an exciting analytical framework that can enhance secondary data analysis in powerful ways. IDA pools item level data across multiple studies to make inferences possible both within and across studies and can be used to test questions not possible in individual contributing studies. Some of the potential benefits of IDA include the ability to study longer developmental periods, examine how the measurement of key constructs changes over time, increase subject heterogeneity, and improve statistical power and capability to study rare behaviors. Our goal in this paper is to provide a brief overview of the benefits and challenges of IDA in developmental research and to identify additional resources that provide more detailed discussions of this topic.

description: Novel and effective analytical calculations of the thermal characteristics of plate heat exchangers have been presented. The basic concept is the use of a reference operation point that is known but must not be necessarily the design point. Three main equations have been established and presented for the heat power and exit temperatures of two flows. They apply to all types of plate heat exchangers in both parallel and counter-flow arrangements and allow the complete thermal characteristics to be calculated by knowing only one reference point. The calculation can be easily performed in tabular form. The conversion equation between parallel and counter-flow arrangements has been provided for calculating the operation points from one arrangement to another. The evidenced thermal relationship between plate heat exchangers with different plate numbers shows that the thermal characteristics of such plate heat exchangers are identical when the proportional reference operating points are applied. The analyses and calculations could be well validated by measurements. Finally, the calculation concept for the thermal characteristics of other heat exchanger types was outlined.

description: Spectra of molecular hydrogen (H$_2$) are employed to search for a possible proton-to-electron mass ratio ($μ$) dependence on gravity. The Lyman transitions of H$_2$, observed with the Hubble Space Telescope towards white dwarf stars that underwent a gravitational collapse, are compared to accurate laboratory spectra taking into account the high temperature conditions ($T \sim 13\,000$ K) of their photospheres. We derive sensitivity coefficients $K_i$ which define how the individual H$_2$ transitions shift due to $μ$-dependence. The spectrum of white dwarf star GD133 yields a $Δμ/μ$ constraint of $(-2.7\pm4.7_{\rm stat}\pm 0.2_{\rm sys})\times10^{-5}$ for a local environment of a gravitational potential $ϕ\sim10^4\ ϕ_\textrm{Earth}$, while that of G29$-$38 yields $Δμ/μ=(-5.8\pm3.8_{\rm stat}\pm 0.3_{\rm sys})\times10^{-5}$ for a potential of $2 \times 10^4$ $ϕ_\textrm{Earth}$.

description: We analyze the topological and dynamical properties of a system formed by two chains of identical emitters coupled to a waveguide, whose guided modes induce all-to-all excitation hopping. We find that, in the single excitation limit, the bulk topological properties of the Hamiltonian that describes the coherent dynamics of the system are identical to the ones of a one-dimensional Su-Schrieffer-Heeger (SSH) model. However, due to the long-range character of the exchange interactions, we find weakening of the bulk-boundary correspondence. This is illustrated by the variation of the localization length and mass gap of the edge states encountered as we vary the lattice constant and offset between the chains. Most interestingly, we analytically identify parameter regimes where edge states arise which are fully localized to the boundaries of the chain, independently of the system size. These edge states are shown to be not only robust against positional disorder of the atoms in the chain, but also subradiant, i.e., dynamically stable even in the presence of inevitable dissipation processes, establishing the capacity of waveguide QED systems for the realization of symmetry protected topological phases.

description: Nella storia recente dell’Astrofisica le infrastrutture informatiche sia di calcolo che di archiviazione e fruizione degli archivi sono state di crescente importanza per la produzione di risultati scientifici di eccellenza. Infrastrutture di piccola e media scala, dalla workstation individuale al centro di calcolo di struttura, hanno lasciato posto alla necessità di accesso a medie e grandi infrastrutture centralizzate a cui garantire accesso ai ricercatori. L’adesione dell’INAF a grandi infrastrutture di ricerca di livello mondiale, ad esempio SKA e CTA, e il crescente proliferare di iniziative nazionali, europee e mondiali di creazioni di cluster di calcolo o cloud di archiviazione condivisi, ha ulteriormente innalzato il livello di esigenze, correnti e future, della comunità scientifica rendendo opportuno un cambio di passo a livello di Ente nell’approvvigionamento, gestione, offerta e coordinamento delle risorse di calcolo ed archiviazione per l’Astrofisica. Esiste pertanto un generale consenso nella comunità circa la necessità di riformare ed aggiornare l’offerta di Information technology (ICT) interna ad INAF per adeguarla alle nuove sfide che si prospettano all’orizzonte, legate ad un ruolo sempre più crescente della componente informatica nella produzione, qualificazione, conservazione e fruibilità del dato osservativo e teorico in Astronomia e Astrofisica. La via maestra, in linea con le tendenze internazionali, è la centralizzazione della ubicazione ed erogazione delle risorse in un contesto di competenze distribuite. Infatti una proliferazione non coordinata di centri di calcolo di piccole dimensioni, quanto si otterrebbe distribuendo senza criterio le componenti di nuova acquisizione presso le varie strutture di ricerca, implicherebbe una crescita dei costi indiretti ed una riduzione dell'efficienza del sistema complessivo causata dalla frammentazione. Passi importanti in questa direzione sono già stati intrapresi dall’Ente. Tra questi il più rilevante è senza dubbio l’investimento nel “tecnopolo” di Bologna, occasione per una azione integrata in un contesto dinamico e riconosciuto a livello governativo e nazionale ed in una prospettiva di medio-lungo termine. Altri importanti passi intermedi sono resi possibili da opportunità come quella recentemente concretizzata di rilevare in comodato d’uso parti del cluster denominato “Galileo” in via di dismissione da parte del CINECA. Questo documento presenta una analisi di scenario delle esigenze attuali o previste per il prossimo futuro in termini di infrastrutture informatiche, l’offerta attualmente disponibile a copertura di queste esigenze e la prospettiva di evoluzione dell’offerta a copertura delle esigenze previste. Il documento include inoltre una proposta di futura governance del settore, basata su un soggetto attuatore autonomo, la e-infrastructure di INAF, ed un soggetto preposto al coordinamento, controllo e ruolo abilitante per il settore, la UTG “Astrofisica Computazionale”.

description: The observed pattern of linear polarization of the cosmic microwave background (CMB) photons is a sensitive probe of physics violating parity symmetry under inversion of spatial coordinates. A new parity-violating interaction might have rotated the plane of linear polarization by an angle $β$ as the CMB photons have been traveling for more than 13 billion years. This effect is known as "cosmic birefringence." In this paper, we present new measurements of cosmic birefringence from a joint analysis of polarization data from two space missions, Planck and WMAP. This dataset covers a wide range of frequencies from 23 to 353 GHz. We measure $β= 0.342^{\circ\,+0.094^\circ}_{\phantom{\circ\,}-0.091^\circ}$ (68% C.L.) for nearly full-sky data, which excludes $β=0$ at 99.987% C.L. This corresponds to the statistical significance of $3.6σ$. There is no evidence for frequency dependence of $β$. We find a similar result, albeit with a larger uncertainty, when removing the Galactic plane from the analysis.

description: Human behavioral studies demonstrate that healthy aging is often accompanied by increases in memory distortions or errors. Here we used event-related functional MRI to examine the neural basis of age-related memory distortions. We utilized the memory conjunction error paradigm, a laboratory procedure known to elicit high levels of memory errors. For older adults, right parahippocampal gyrus showed significantly greater activity during false than during accurate retrieval. We observed no regions in which activity was greater during false than during accurate retrieval for young adults. Young adults, however, showed significantly greater activity than old adults during accurate retrieval in right hippocampus. By contrast, older adults demonstrated greater activity than young adults during accurate retrieval in right inferior and middle prefrontal cortex. These data are consistent with the notion that age-related memory conjunction errors arise from dysfunction of hippocampal system mechanisms, rather than impairments in frontally-mediated monitoring processes.

The Effects of Attention on Age-related Relational Memory Deficits: fMRI Evidence from a Novel Attentional Manipulation

description: Numerous studies have documented that older adults (OAs) do not perform as well as young adults (YAs) when task demands require the establishment or retrieval of a novel link between previously unrelated information (relational memory: RM). Nonetheless, the source of this age-related RM deficit remains unspecified. One of the most widely investigated factors is an age-related reduction in attentional resources. To investigate this factor, previous researchers have tested whether dividing YAs' attention during encoding equated their RM performance to that of OAs. However, results from these studies failed to replicate the age-related RM impairment observed in aging. The current study investigated whether a reduction in attentional resources for processing of relational information (i.e., relational attention) underlies age-related RM deficits. Using fMRI, we examined whether the effect of reduced attentional resources for processing of relational information is similar to that observed in aging at both behavioral and neural levels. The behavioral results showed that reduced attentional resources for relational information during encoding equated YAs RM performance to that of OAs. Furthermore, the fMRI results demonstrated that both aging, as well as reductions in relational attention in YAs, significantly reduced activity in brain areas associated with successful RM formation, namely, the ventrolateral and dorsolateral PFC, superior and inferior parietal regions, and left hippocampus. Such converging evidence from behavioral and neuroimaging studies suggests that a reduction in attentional resources for relational information is a critical factor for the RM deficit observed in aging.
SCREENING OF PATIENT ADHERENCE IN THE TREATMENT OF CHRONIC NON-INFECTIOUS DISEASES
Creators: name: Khodjieva, G.S.

Publisher: name: Zenodo
Year: 2025

description: Today, the problem of chronic non-communicable diseases (CND) in modern society remains socially and medically relevant due to significant prevalence, high level of disability and mortality. The studied data of long-term studies indicate insufficient secondary prevention of CND both at the population level and among individuals with a high risk of its development. Among the reasons for this situation, a special place is given to insufficient patient adherence to drug and non-drug therapy. The study of patients' attitudes to the prescribed therapy and the degree of its compliance is a fairly new area of scientific research. The development of this area is due to the large role of the paradigm of interaction between doctor and patient, the transition from a paternalistic model to partnerships and the patient's awareness of his own active role in therapy.

description: In this paper we develop a hybrid version of the encounter-based approach to diffusion-mediated absorption at a reactive surface, which takes into account stochastic switching of a diffusing particle's conformational state. For simplicity, we consider a two-state model in which the probability of surface absorption depends on the current particle state and the amount of time the particle has spent in a neighborhood of the surface in each state. The latter is determined by a pair of local times $\ell_{n,t}$, $n=0,1$, which are Brownian functionals that keep track of particle-surface encounters over the time interval $[0,t]$. We proceed by constructing a differential Chapman-Kolmogorov equation for a pair of generalized propagators $P_n(\x,\ell_0,\ell_1,t)$, where $P_n$ is the joint probability density for the set $(\X_t,\ell_{0,t},\ell_{1,t})$ when $N_t=n$, where $\X_t$ denotes the particle position and $N_t$ is the corresponding conformational state. Performing a double Laplace transform with respect to $\ell_0,\ell_1$ yields an effective system of equations describing diffusion in a bounded domain $Ω$, in which there is switching between two Robin boundary conditions on $\partial Ω$. The corresponding constant reactivities are $κ_j=D z_j$, $j=0,1$, where $z_j$ is the Laplace variable corresponding to $\ell_j$ and $D$ is the diffusivity. Given the solution for the propagators in Laplace space, we construct a corresponding probabilistic model for partial absorption, which requires finding the inverse Laplace transform with respect to $z_0,z_1$. We illustrate the theory by considering diffusion of a particle on the half-line with the boundary at $x=0$ effectively switching between a totally reflecting and a partially absorbing state. Finally, we indicate how to extend the analysis to higher spatial dimensions using the spectral theory of Dirichlet-to-Neumann operators.

description: We start a systematic investigation of possible isometries of the asymptotically de Sitter solutions to Einstein equations. We reformulate the Killing equation as conformal equations for the initial data at $\mathcal{I}^+$. This allows for partial classification of possible symmetry algebras. In particular, if they are not maximal, they may be at most $4$-dimensional. We provide several examples. As a simple collorary it is shown that the only spacetime in which the Killing horizon intersects $\mathcal{I}^+$ (after a conformal completion) is locally the de Sitter universe.

description: To accurately calculate efficiencies $η$ of experimentally produced multijunction solar cells (MJSCs) and optimize their parameters, we offer semi-analytical photoconversion formalism that incorporates radiative recombination, Shockley-Read-Hall (SRH) recombination, surface recombination at the front and back surfaces of the cells, recombination in the space charge region (SCR) and the recombination at the heterojunction boundaries. Selfconsistent balance between the MJSC temperature and efficiency was imposed by jointly solving the equations for the photocurrent, photovoltage, and heat balance. Finally, we incorporate into the formalism the effect of additional photocurrent decrease with subcell number increase. It is shown that for an experimentally observed Shockley-Read-Hall lifetimes, the effect of re-absorption and re-emission of photons on MJSC efficiency can be neglected for non-concentrated radiation conditions. A significant efficiency $η$ increase can be achieved by improving the heat dissipation using radiators and bringing the MJSC emissivity to unity, that is closer to black body radiation rather than grey body radiation. Our calculated efficiencies compare well with other numerical results available and are consistent with the experimentally achieved efficiencies. The formalism can be used to optimize parameters of MJSCs for maximum photoconversion efficiency.

This means that the propagation constants of modes of the corresponding complex optical potential are real. A class of such waveguides is found from a relation between two spectral problems. A particular example of an asymmetric waveguide, described by the hyperbolic functions, is analyzed. The existence and stability of linear modes and of continuous families of nonlinear modes are demonstrated.

description: Researching and addressing “radicalization” within smaller European countries is particularly challenging. Not only is it incumbent that research and approaches take into account analyses, findings, strategies, and measures from other contexts, they must also work to craft their own national understanding of the extent and nature of the phenomena and approaches to address it. This chapter discusses the author’s reflections on experiences conducting two studies on violent jihadist1 radicalization in Switzerland at a time of heightened concern over potential jihadist violent extremist threats.2 In doing so, the chapter focuses on the ethical and methodological challenges specific to the Swiss context, as well as issues impacting research on violent extremism more generally. The two studies—both of which the author served a role in—additionally navigated the tension inherent in researching a topic of heightened public interest and media coverage.
Given the context and the focus on jihadist extremism specifically, the research processes themselves carried risks, including the risk of inadvertently enhancing social polarization and Islamophobia in the very act of examining a phenomenon focused on minority populations in a small country. Methodological challenges additionally complicated the research, but also provided opportunities brought on by the diverse backgrounds of the researchers in terms of their disciplines, the nature of their work on violent extremism, and their sociocultural and linguistic backgrounds (from German-, French- and Italian-speaking parts of Switzerland). The researchers also faced demanding timelines, undertaking research during a time when concerns over a possible terrorist attack were heightened, placing additional pressure on the researchers in charge of making decisions focused on both handling emergency and ethical concerns in an accurate, institutionally prescribed manner and addressing societal concerns pragmatically. Additional issues specific to the Swiss context included: (1) the challenge of managing and safeguarding data and anonymity in a country with a relatively small population; and (2) gaining and maintaining access to the trust of research participants.
This chapter reflects on approaches to mitigate these challenges and examines the research process in retrospect from the perspective of the author. It concludes with recommendations based on the research projects focused on mitigating potential risks, particularly those to research participants and their associated demographic populations, when researching violent extremism and other sensitive topics in the Swiss context. While the chapter focuses on research conducted on violent extremism in Switzerland, its insights may have utility in addressing similar challenges elsewhere.
Reduced Specificity of Hippocampal and Posterior Ventrolateral Prefrontal Activity during Relational Retrieval in Normal Aging

description: Neuroimaging studies of episodic memory in young adults demonstrate greater functional neural activity in ventrolateral prefrontal cortex and hippocampus during retrieval of relational, as compared to item, information. We tested the hypothesis that healthy older adults – individuals who exhibit behavioral declines in relational memory – would show reduced specificity of ventrolateral prefrontal and hippocampal regions during relational retrieval. At study, participants viewed two nouns and were instructed to covertly generate a sentence that related the words. At retrieval, functional magnetic resonance images were acquired during item and relational memory tasks. In the relational task, participants indicated whether the two words were previously seen together. In the item task, participants indicated whether both items of a pair were previously seen. In young adults, left posterior ventrolateral PFC and bilateral hippocampal activity was modulated by the extent to which the retrieval task depended on relational processing. In older adults, activity in these regions was equivalent for item and relational memory conditions, suggesting a reduction in ventrolateral PFC and hippocampal specificity with normal aging.
Effects of Acute Dopamine Precusor Depletion on Immediate Reward Selection Bias and Working Memory Depend on Catechol- O -methyltransferase Genotype

description: Little agreement exists as to acute dopamine (DA) manipulation effects on intertemporal choice in humans. We previously found that catechol-O-methyltransferase (COMT) Val158Met genotype predicts individual differences in immediate reward selection bias among adults. Moreover, we and others have shown that the relationship between COMT genotype and immediate reward bias is inverted in adolescents. No previous pharmacology studies testing DA manipulation effects on intertemporal choice have accounted for COMT genotype, and many have included participants in the adolescent age range (18–21) as adults. Moreover, many studies have included female subjects without strict cycle phase control, although recent evidence demonstrates that cyclic estradiol elevations interact with COMT genotype to affect DA-dependent cognition. These factors may have interacted with DA manipulations in past studies, potentially occluding detection of effects. Therefore, we predicted that among healthy adult males (ages 22–40), frontal DA tone, as indexed by COMT genotype, would interact with acute changes in DA signaling to affect intertemporal choice. In a double-blind, placebo-controlled design, we decreased central DA via administration of an amino acid beverage deficient in the DA precursors, phenylalanine and tyrosine (P/T[−]), and tested effects on immediate reward bias in a delay-discounting (DD) task and working memory (WM) in an n-back task. We found no main effect of beverage on DD or WM performance, but did find significant beverage*genotype effects. These results suggest that the effect of DA manipulations on DD depends on individual differences in frontal DA tone, which may have impeded some past efforts to characterize DA’s role in immediate reward bias in humans.

description: A non-negligible fraction of binary neutron star mergers are expected to form long-lived neutron star remnants, dramatically altering the multi-messenger signatures of a merger. Here, we extend existing models for magnetar-driven kilonovae and explore the diversity of kilonovae and kilonova afterglows. Focusing on the role of the (uncertain) magnetic field strength, we study the resulting electromagnetic signatures as a function of the external dipolar and internal toroidal fields. These two parameters govern, respectively, the competition between magnetic-dipole spindown and gravitational-wave spindown (due to magnetic-field deformation) of the rapidly-rotating remnant. We find that even in the parameter space where gravitational-wave emission is dominant, a kilonova with a magnetar central engine will be significantly brighter than one without an engine, as this parameter space is where more of the spin-down luminosity is thermalised. In contrast, a system with minimal gravitational-wave emission will produce a kilonova that may be difficult to distinguish from ordinary kilonovae unless early-epoch observations are available. However, as the bulk of the energy in this parameter space goes into accelerating the ejecta, such a system will produce a brighter kilonova afterglow that will peak on shorter times. To effectively hide the presence of the magnetar from the kilonova and kilonova afterglow, the rotational energy inputted into the ejecta must be $\lesssim 10^{-3}-10^{-2} E_{\rm rot}$. We discuss the different diagnostics available to identify magnetar-driven kilonovae in serendipitous observations and draw parallels to other potential magnetar-driven explosions, such as superluminous supernovae and broad-line supernovae Ic.

description: Die Customer Management Studie zeigt die wichtigsten Trends im Kundenmanagement im DACH-Raum aus Unternehmenssicht auf. Die aktuellen Krisen haben teilweise als weitere Beschleuniger des Wandels gewirkt und die Notwendigkeit, die wichtigen Trends für das eigene Unternehmen zu erkennen und darauf zu reagieren, nochmals erhöht. 219 Unternehmensvertreterinnen und -vertreter aus der Schweiz, Deutschland und Österreich haben für diese Studie ihre Einschätzungen geteilt und ermöglichen den Lesenden ein Benchmarking für ihr Unternehmen. Namhafte Expertinnen und Experten der Partnerunternehmen und Verbände bereichern die Studie durch Statements und Praxiscases und ordnen die Ergebnisse ein.
Unternehmen legen in diesem Jahr den Schwerpunkt im Kundenlebenszyklus mehrheitlich auf die Kundenbindung. Betreffend Digitalisierung der Kundenbeziehung befindet sich rund die Hälfte der befragten Unternehmen noch eher am Anfang, obwohl es einen wichtigen Faktor für die individuelle Kundenkommunikation darstellt und kundenorientiertes Verhalten ermöglicht. Dahingegen wird CRM-Software wie in den bisherigen Jahren von über zwei Dritteln der Unternehmen zur Sammlung von Kundendaten eingesetzt. Ein aufkommendes Thema heisst dabei Customer Data Platform (CDP). Lediglich die Hälfte der Befragten gab an von CDPs gehört zu haben. Diese Hälfte ist häufig schon an konkreten Einführungsschritten. Das überrascht nicht, denn die potenziellen Vorteile von CDPs sind für die meisten Unternehmen sehr attraktiv.
Künstliche Intelligenz (KI) wird in den Kundenbeziehungen bereits in vielen Anwendungen eingesetzt und die Kommunikation verläuft Mensch zu Maschine zu Mensch. Insbesondere die digitale Kommunikation und Werbung wird häufig von Algorithmen gefiltert und gesteuert. Dies ist jedoch vielen teilnehmenden Unternehmen bisher nicht bewusst. Der nächste Level wäre der bewusste und gezielte Einsatz von KI, um die jeweiligen Vorteile von Mensch und Maschine in den Kundenbeziehungen optimal zu nutzen.
Nachhaltigkeit gilt als einer der wirkmächtigsten Megatrends der Gegenwart. Das erzeugt Handlungsdruck: Unternehmen müssen Stellung beziehen, wie sie zur Nachhaltigkeit stehen. Die grosse Mehrheit wird mit Nachhaltigkeitsforderungen von Kundinnen und Kunden und sogar noch stärker von Mitarbeitenden konfrontiert.
Die vorliegende Studie zeigt auf, dass der Wandel im Kundenmanagement ungebrochen ist und die Unternehmen auch hier agil sein müssen. Insbesondere muss das Gleichgewicht von Daten und Emotionen sowie Mensch und Maschine immer wieder neu austariert werden.
Genetic Polymorphisms Regulating Dopamine Signaling in the Frontal Cortex Interact to Affect Target Detection under High Working Memory Load

description: Frontal-dependent task performance is typically modulated by dopamine (DA) according to an inverted-U pattern, whereby intermediate levels of DA signaling optimizes performance. Numerous studies implicate trait differences in DA signaling based on differences in the catechol-O-methyltransferase (COMT) gene in executive function task performance. However, little work has investigated genetic variations in DA signaling downstream from COMT. One candidate is the dopamine- and cAMP-regulated phosphoprotein of molecular weight 32 kDa (DARPP-32), which mediates signaling through the DA D1-type receptor, the dominant DA receptor in the frontal cortex. Using an n-back task, we used signal detection theory to measure performance in a healthy adult population (n=97) genotyped for single nucleotide polymorphisms in the COMT (rs4680) and DARPP-32 (rs907094) genes. Correct target detection (hits), and false alarms were used to calculate d' measures for each working memory load (0-, 2-, and 3-back). At the highest load (3-back) only, we observed a significant COMT×DARPP-32 interaction, such that the DARPP-32 T/T genotype enhanced target detection in COMTValVal individuals, but impaired target detection in COMTMet carriers. These findings suggest that enhanced dopaminergic signaling via the DARPP-32 T allele aids target detection in individuals with presumed low frontal DA (COMTValVal) but impairs target detection in those with putatively higher frontal DA levels (COMTMet carriers). Moreover, these data support an inverted-U model with intermediate levels of DA signaling optimizing performance on tasks requiring maintenance of mental representations in working memory.

description: Resumo:

O artigo trata da relação entre religião e política na definição de comportamentos políticos em debate na esfera pública institucional brasileira, procurando mostrar como o tema da secularização do Estado pode ser trabalhado sob a perspectiva da diferenciação funcional, tal qual utilizada na teoria social de Niklas Luhmann. Na busca de uma compreensão sistêmica da comunicação religiosa e de sua complexa aliança com a moral socialmente difundida, levantar-se-á a hipótese da reprodução de uma seletividade dos discursos sobre o secularismo no Brasil, que, longe de garantir a equidistância estatal em relação às diversas crenças, possibilita uma ocupação privilegiada do espaço público por determinados grupos religiosos na pauta discursiva sobre diversas políticas públicas.

 Abstract:

The paper discusses the relationship between religion and politics in the definition of political behavior in institutional public sphere in Brazil, trying to show how the theme of secularization of the state can be worked from the perspective of functional differentiation, conceptual categories used in Niklas Luhmann’s social theory. In search of a systemic understanding of religious communication and its alliance with the complex moral socially pervasive, it will raise the chance of playing a selectivity of discourses on secularism in Brazil, which, far from guaranteeing the impartiality state in relation the diverse beliefs, enables a privileged occupation of public space by certain religious groups in discursive agenda on various public policies.

description: The challenge in deploying computer vision workloads is the decision as to where the computation of the video streams occurs across the edge-to-cloud continuum. The decisions are based on business, technical and workload variables, which may be dynamic in nature. This thesis proposes a Computer Vision Workload Manager, which will provide an open framework for deploying and managing active workloads across physical and virtualised environments. The benchmarking tests demonstrated that edge devices with higher powered processing capabilities delivered superior performance in terms of MIPS/watt and using virtualisation techniques can also provide increased CPU processing performance by up to 22%. The video analytics workload testing demonstrated the significant difference in processing requirements with different video stream bitrates and how video stream saliency affects processing requirements on edge devices by up to 15%. Using the test results, use cases from two industries were then used to demonstrate how the computer vision workload manager provides power management, load balancing, and deployment of new and prioritised workloads. The computer vision workload manager is designed as a framework to bring together a group of edge devices and cloud instances to deliver computer vision workloads. The ability and flexibility for the system to be extended to ensure the business, technical and workload requirements of different workloads and its ability to use current and emerging edge platform technologies are critical to its successful implementation.
