description: The Cape mole-rat (Georychus capensis) is a solitary, strictly subterranean rodent that is responsive to light and entrains to photic cues despite having a reduced visual system. Circadian entrainment is maintained throughout life, but age can alter the amplitude of the response and re-entrainment time. Mole-rats are long-lived for their size which raises questions regarding the robustness of their circadian rhythms and how impacts their locomotor activity rhythms. The locomotor activity rhythms of juvenile and adult Cape mole-rats were investigated. They were exposed to pre-experimental and post-experimental control cycles under fluorescent lights, six 12 h light:12 h dark cycles of decreasing intensities and a constant dark cycle (DD). All animals exhibited more activity during the dark phases of all light regimes. Juveniles were more active than adults and displayed more variable activity during both the light and dark phases. Adults exhibited relatively stable levels of activity under all experimental conditions, whereas juvenile activity decreased as the light intensity was reduced. The amplitude of Cape mole-rat rhythms was consistently low, but similar across light regimes and between adults and juveniles. Cape mole-rats have functional circadian systems, are primarily nocturnal and respond differentially to light intensity depending on their age. Light intensity does not affect the locomotor activity responses of Cape mole-rats in a predictable manner, and could indicate more complex interactions with light wavelengths. The circadian systems of juveniles appear to be more sensitive than those of adults, although the mechanism of the light response remains unclear.

description: This thesis deals with the frequency of evaluations in employment relationships using microeconomic theory. In particular, it analyzes the behavior of a principal with bounded memory who can offer a two-period performance-based contract to one or several agents. After a review of relevant literature, this work contains three detailed models. In the first model, both parties are risk-neutral and the principal can choose whether to evaluate the agent after each period or only at the end of the second period. If the agent is wealth-constrained, the option to evaluate him twice can be profitable. But without the constraint on the part of the agent, the principal will always prefer to evaluate only once in order to reduce evaluation costs. We also consider a modification of the profit function that can be interpreted as depreciation. Again, this leads to a trade-off between more and less frequent evaluations. The second model builds on the first, introducing risk aversion of the agent as additional element. We show that risk aversion on behalf of the agent creates a decision problem concerning the risk-neutral principal's choice on the evaluation frequency. The optimal evaluation frequency will be determined by trading off the efficiency loss induced by the principal's bounded memory against the cost of an additional evaluation. We extend this setup to heterogeneously forgetful principals who compete for an agent. Competition has no impact on the optimal evaluation frequency, but as the agent is risk-averse, the less forgetful principal has a comparative advantage and can make a positive profit when a contract with one evaluation is implemented. The third model investigates whether a differentiation in the frequency of employee evaluations can enhance an employer's ability to offer profitable screening contracts to heterogeneously productive agents. As performance data cannot be perfectly memorized over time, incentives crucially depend on the frequency with which this data is made explicit. The memory-bounded principal offers two-period performance-based contracts to a population of agents who are privately informed about their type. Compared to a situation with symmetric information, optimal screening contracts may include different evaluation frequencies for different types under asymmetric information.

description: The link between vitamin D deficiency (VDD) and sleep disturbances has long been suggested. However, the direct causality between VDD, sleep disturbances, and circadian rhythm remains unclear. We aimed to characterize sleep-wake behavior and circadian rhythms in an animal model of VDD. VDD was induced by feeding vitamin D-deficient chow, and we analyzed sleep and circadian rhythm parameters. During light period, VDD mice exhibited reduced wake with more frequent wake bouts and increased NREM sleep time. However, during dark period, the wake EEG power spectrum peaked at theta band frequency, and slow-wave energy was suppressed in mice with VDD. Rest-activity analyses revealed increased circadian period, lower wheel counts, and more frequent and short activity bouts during VDD. Combining sleep and circadian data, we found significantly suppressed activities during the hours with a wake duration shorter than 30 minutes. Moreover, mice in VDD state exhibited a negative correlation between wake theta power and hourly wheel-running counts during dark period. Our data point to a direct link between VDD and disturbances in sleep and rest-activity circadian rhythm, featuring frequent wake bouts during the sleeping phase, reduced sleep pressure build-up in dark period, and reduced activity levels due to increased susceptibility to sleepiness.

description: One of the poorest areas of Vietnam, the Northern Mountainous Region (NMR) is largely populated by ethnic minorities. Women in these communities produce heritage breeds of pork on a smaller scale, providing them with opportunities and agency. This production also brings alternative sources of revenue outside of the cultivation of rice and corn, maintains genetic diversity, and continues indigenous knowledge systems of livestock management that have contributed to the resiliency of local communities for generations. Drawing on fieldwork in eight villages in Bac Kan and Lao Cai provinces, each populated differently by Hmong, Nung, San Chi, and Tay peoples, this article focuses on new forms of vulnerability brought on by African swine fever. With fieldwork conducted at different stages of the pandemic, African swine fever was found to be not only devastating local pigs but also strongly impacting the sustainable future of smaller-scale farming and the very livelihoods of many ethnic minority populations across the NMR. Overall, this article draws on this moment of crisis to provide strong evidence in support of nuanced policymaking that considers the complex and multi-scale interactions between geography, marginalization, ethnicity, and culture.

description: Background: The diversity of symptoms associated with Parkinson’s and their impact on functioning have led to an increased interest in exploring factors that impact Health-Related Quality of Life (HRQoL). Although the experience of Parkinson’s is unique, some symptoms have a greater impact than others, e.g. depression. Moreover, as the risk of Parkinson’s increases with age, the fnancial and public health impact of this condition is likely to increase, particularly within the context of a globally ageing population. In Ireland, research is ongoing in the pursuit of causes and efective treatments for Parkinson’s; however, its impact on everyday living, functioning, and HRQoL is largely under-examined. This study aims to describe factors that infuence HRQoL for people with Parkinson’s (PwP) in one region of Ireland. Methods: A cross-sectional postal survey was conducted among people living with Parkinson’s (n=208) in one area of Ireland. This survey included socio-demographic questions, Nonmotor Symptoms Questionnaire for Parkinson’s disease (NMSQuest), the Geriatric Depression Scale (GDS-15), and the Parkinson’s disease Questionnaire (PDQ?39). Statistical analysis was conducted using SPSS, IBM version 25 (SPSS Inc., Chicago, II, USA). Results: Participants refected a predominantly older population who were married, and lived in their own homes (91%). Participants diagnosed the longest reported poorer HRQoL regarding mobility, activities of daily living, emo?tional well-being, social support, cognition, communication domains and overall HRQoL. Lower HRQoL correlated with higher depression scores p<0.001 and participants in the lower HRQoL cohort experienced 2.25 times more non-motor symptoms (NMSs) than participants with higher HRQoL. Hierarchical multiple linear regression analysis predicted Geriatric Depression Scale (GDS15) score, NMS burden, and years since diagnosis to negatively impact HRQoL. Principal component analysis (PCA) also indicated that for the population in this study, components measuring 1) independence/dependence 2) stigma 3) emotional well-being, and 4) pain were central to explaining core aspects of participants’ HRQoL. Conclusions: Findings highlighted the negative impact of longer disease duration, NMS burden, depression, mobility impairments, and perceived dependence on HRQoL for PwP. The positive infuence of perceived independence, social engagement along with close supportive relationships were also identifed as key components determining HRQoL. Findings emphasised the importance of long-term healthcare commitment to sustaining social and community supports and therapeutic, rehabilitative initiatives to augment HRQoL for PwP

description: This comparative study explores the legal and ethical perspectives on euthanasia in India and Canada. Euthanasia, also known as assisted dying, is a complex and controversial issue that raises questions about autonomy, dignity, suffering, and the role of healthcare professionals in end-of-life decision-making. In Canada, euthanasia is legal under certain circumstances, following the Supreme Court's decision in the Carter case in 2015. The Medical Assistance in Dying (MAID) Act came into effect in 2016, which allows eligible patients to receive medical assistance in dying with the supervision of a medical practitioner. However, the law has strict criteria for eligibility, and there is ongoing debate about expanding its scope. In India, euthanasia is illegal under the Indian Penal Code. However, there have been several high-profile cases in recent years that have brought the issue to public attention, such as the Aruna Shanbaug case in 2011. The debate in India has focused on the right to die with dignity and the need for a legal framework that addresses end- of-life care and decision-making. This study compares the legal frameworks and ethical perspectives on euthanasia in both countries, examining the cultural and historical factors that shape attitudes towards end-of-life care. It explores the role of religion, family, and social values in shaping public opinion and policy and considers the impact of globalisation and changing demographics on the debate.

Literature. Platia (2015a: 11): first record from Pakistan, figures of male habitus, antenna and genitalia.
Remark. The species considered to be A. consobrinus from Pakistan by Platia (2015a) is most probably not conspecific with A. consobrinus lectotype deposited in the Natural History Museum in London, UK (NHMUK). The lectotype of A. consobrinus have pronotum without any elevations. Agrypnus consobrinus sensu Platia (2015a) probably belongs to “ A. binodulus species group”, whose representatives have two tubercles on the pronotal disk. Based on the comparison of images by Platia (2015a) and the photograph of the lectotype of A. orientalis deposited in NHMUK, the species studied by Platia could be A. orientalis Hope, 1843. Unfortunately, the type locality and distribution of this species is rather unclear (Hayek 1973).

description: The first Weyl algebra over $k$, $A_1 = k \langle x, y\rangle/(xy-yx - 1)$ admits a natural $\mathbb{Z}$-grading by letting $\operatorname{deg} x = 1$ and $\operatorname{deg} y = -1$. Paul Smith showed that $\operatorname{gr}- A_1$ is equivalent to the category of quasicoherent sheaves on a certain quotient stack. Using autoequivalences of $\operatorname{gr}- A_1$, Smith constructed a commutative ring $C$, graded by finite subsets of the integers. He then showed $\operatorname{gr}- A_1 \equiv \operatorname{gr}- (C, \mathbb{Z}_{\mathrm{fin}})$. In this paper, we generalize results of Smith by using autoequivalences of a graded module category to construct rings with equivalent graded module categories. For certain generalized Weyl algebras, we use autoequivalences defined in a companion paper so that these constructions yield commutative rings.

description: FAIR-IMPACT is developing guidelines and a prototype to expose relevant information as metadata to facilitate discovery, provide context, support interoperability, and create a sense of trust in service providers and the services they offer. Transparent and linked information between objects, the repositories that hold or interact with them, and the registries and portals that use this information, can be indexed, harvested, reused, and potentially validated against agreed criteria or by designated validation authorities to improve collaboration and trust between stakeholders. The guidelines and technical implementation of them are intended to flexibly fit different use cases and scenarios that occur in the research data landscape, which is why we collect community input during the development of them. This input will directly feed into next iterations of the work.

description: Die Forderung nach Schonung der Ressourcen und Verringern der Abfallmengen führt zu einer Abkehr von der reinen Abfallbeseitigung hin zu einer Kreislaufwirtschaft. Damit stellt sich zunehmend auch die Herausforderung, Altprodukte in einer möglichst wirtschaftlichen Form zu recyceln. Wegen der nicht gegebenen gezielten Schadstoffseparierung sonstiger Techniken zur Wertstofftrennung wird es durch eine vorgeschaltete Demontage erst möglich, hochwertige Stoffkreisläufe zu schließen und drohende Umweltbelastungen zu reduzieren. Untersuchungen in den heutigen Rückbauzentren zeigen eine hohe physische Belastung der Werker sowie eingeschränkte manuelle Demontageleistung infolge der unzureichenden Ar-beitsbedingungen und des geringen Mechanisierungsgrades.Der Handlungsbedarf im Hinblick auf die Weiterentwicklung der Demontage ist daher evi-dent. Die kostenaufwändige manuelle Demontage führt zu Überlegungen, durch flexible Ro-boter die Wirtschaftlichkeit zu verbessern.Das vorliegende Buch leistet hier einen wichtigen Beitrag zur Schaffung wissenschaftlicher Grundlagen und zur Einführung wirtschaftlicher Lösungen für die flexible Automatisierung der Demontage.Es werden die Probleme der Demontageautomatisierung aufgezeigt und Optimierungsansätze innerhalb einer realisierten automatischen Demontagezelle analysiert. Das größte Potential hinsichtlich Prozesszeit und Prozesssicherheit liegt dabei in der Optimierung des Trennens von Schraubenverbindungen. Hierfür werden unterschiedliche Demontagestrategien bewertet. Auf Basis der Analyse von Schraubverbindungen und der Trennprozesse erfolgt die morpho-logische Konzipierung eines Trennwerkzeuges mit Ausgleichsmodul für Schraubverbindun-gen.Der realisierte Prototyp zeigt innerhalb verschiedener Versuchsreihen die Erfüllung des An-forderungsprofils hinsichtlich der Reduzierung der Prozesszeiten und der Verbesserung der Prozesssicherheit.

description: Semidefinite programs (SDPs) can be solved in polynomial time by interior point methods, but scalability can be an issue. To address this shortcoming, over a decade ago, Burer and Monteiro proposed to solve SDPs with few equality constraints via rank-restricted, non-convex surrogates. Remarkably, for some applications, local optimization methods seem to converge to global optima of these non-convex surrogates reliably. Although some theory supports this empirical success, a complete explanation of it remains an open question. In this paper, we consider a class of SDPs which includes applications such as max-cut, community detection in the stochastic block model, robust PCA, phase retrieval and synchronization of rotations. We show that the low-rank Burer--Monteiro formulation of SDPs in that class almost never has any spurious local optima.

description: Returning to the Disc Brooch from Grave 422 in Chiaromonte, San Pasquale (Prov. Potenza / I): Observations and Interpretative Proposals The disc brooch from the Early Medieval cemetery of Chiaromonte, San Pasquale (prov. Potenza / I), represents a valuable goldsmith’s product from Southern Italy and has been known about since the mid-1990s. The extensive study of the technical and decorative analysis of the brooch allowed a broader reflection on the manufacturing process of the piece of jewellery and on the relationship between the craftsman and his client. This information, together with the data from the discovery context, is extremely useful for tracing the effective purchasing power of an elite group who settled and were buried in the central Sinni Valley during the 7th century. A little girl (grave 422) was part of this group and she was buried near an assumed Early Medieval church with the richest funerary assemblage of the cemetery.

description: We determine the non-Abelian version of the four longitudinal form factors of the quark-gluon vertex, using exact expressions derived from the Slavnov-Taylor identity that this vertex satisfies. In addition to the quark and ghost propagators, a key ingredient of the present approach is the quark-ghost scattering kernel, which is computed within the one-loop dressed approximation. The vertex form factors obtained from this procedure are evaluated for arbitrary Euclidean momenta, and display features not captured by the well-known Ball-Chiu vertex, deduced from the Abelian (ghost-free) Ward identity. The potential phenomenological impact of these results is evaluated through the study of special renormalization-point-independent combinations, which quantify the strength of the interaction kernels appearing in the standard quark gap and Bethe-Salpeter equations.

description: Particle swarm optimization (PSO) is one of the metaheuristic optimization methods. Because of its many advantages, it is often used to solve real-world engineering problems. However, in case of complex, multi-dimensional tasks, PSO faces some problems related to premature conver-gence and stagnation in local optima. To eliminate this inconveniences, in this paper, a new learning multi-swarm particle swarm optimization method (LMPSO) with local search operator has been proposed. The presented ap-proach was tested on a set of nonlinear functions and a CEC2015 test suite. The obtained results were compared with other optimization methods.

description: Der Produktentwicklungsprozess ist zu einem der wesentlich Faktoren und Stellschrau-ben für den wirtschaftlichen Erfolg heutiger Produkte und deren Lebenszyklen gewor-den. Mittels Integrität und Standardisierung muss ein hoher Prozessüberlappungsgrad realisiert werden, um schneller, mit gesicherter Qualität und zu wirtschaftlichen Kosten ein Produkt auf den Markt bringen zu können. Das Freigabemanagement wird als das maßgebliche Instrumentarium im Zuge des Simultaneous Engineering zur Verkürzung der Produktentstehungszeit durch Prozessparallelisierung genutzt und individuellen Entwicklungsszenarien angepasst. Der präventiven Methodik des Freigabemanagements wird zudem das Änderungsmanagement als reaktive Vorgehensweise adaptiert. Durch zunehmend räumlich verteilte Entwicklungsvorhaben muss mit Prozessparallelisie-rungsbestrebungen eine Kommunikationsintensivierung einhergehen. Zu diesem Zweck wird ein Assistenzsystem entwickelt, dass es dem Entwickler erlaubt, Kommunikati-onsinstanz, -art und -intervall für einen individuellen Entwicklungsfall bestimmen zu können. Ein abschließendes Anwendungsbeispiel stellt den Praxisbezug her.
description: The product development process became a substantial factor and adjustment for the economic success of today's products and their life cycles. By means of integrity and standardization, a high process parallelization degree must be realized, in order to re-lease products faster, with secured quality and economic market prices. The release management is used as the most relevant method in the course of Simultaneous Engi-neering for the shortening of the product development time by process parallelization. Releases, as a preventive method, and changes with a reactive character have to be adapted to individual development cases. By increasingly distanced development proj-ects, process parallelization requires communication intensification. For this purpose an assistance system is developed that permits the developer to define communication in-stances, communication kinds and communication intervals for an individual case of development. A case study establishes a practical purchase.

Als Ergebnis lässt sich festhalten, dass die Lage der Fundstellen in unmittelbarer Nähe eines Vorfluters – in drei von vier Fällen überdeckt von kolluvialen Ablagerungen – ihre Detektion anhand von Oberflächenfunden erschwerte bzw. unmöglich machte. Diese Maskierung der Fundstellen bietet einen Erklärungsansatz für die Tatsache, dass wir bislang vergleichsweise wenige aussagekräftige archäologische Fundstellen des Frühmittelalters anhand von (keramischen) Oberflächenfunden erfassen konnten. Darüber hinaus ist die damals genutzte Handaufbauware von Keramik aus älteren Perioden nur schwer zu unterscheiden, sodass eine Datierung der Fundplätze in allen Fällen nur durch größtenteils importierte Drehscheibenware (aus dem Rheinland oder hessischen Raum) möglich war. Die Durchsicht des keramischen Materials erbrachte zudem erste Hinweise darauf, dass im südwestfälischen Schiefer­gebirge unter Nutzung der lokalen Ressourcen (u. a. Schiefer als Magerung) im Frühmittelalter drehscheibengefertigte Wölbwandtöpfe produziert wurden.

Specification of Tools with GTSL

description: The definition of software development methods encompasses the definition of syntax and static semantics of specification languages. These languages determine documents to be produced during the application of a method. Developers demand language-based tools that provide document production support, check syntax and static semantics of documents and thus implement methods. A number of methods are used in the different tasks of software construction and a need arises for their integration. This method integration must determine inter-document consistency constraints between documents produced in the various tasks. The various tools that are used during the process must, therefore, be integrated in a way that they implement the required method integration. Unfortunately, the particular mix of methods that is used in one software process need not be appropriate for another. Method integration must, therefore, become part of process modelling and tool integration must be adjusted for each different process. The focus of this paper is on the specification of integrated tools. We outline the main concepts of a dedicated, object-oriented tool specification language, namely GTSL. The language was defined, implemented and evaluated in the GOODSTEP project. Part of the evaluation was the construction of a set of integrated tools for C++ class library maintenance for British Airways, an industrial project partner.

description: We relate the local specification and periodic shadowing properties. We also clarify the relation between local weak specification and local specification if the system is measure expansive. The notion of strong measure expansiveness is introduced, and an example of a non-expansive systems with the strong measure expansive property is given. Moreover, we find a family of examples with the $N$-expansive property, which are not strong measure expansive. We finally show a spectral decomposition theorem for strong measure expansive dynamical systems with shadowing.

Arme ou symbole: étude d’une singulière pointe de flèche en os de la période mérovingienne découverte en Alsace

description: Arme ou symbole: étude d’une singulière pointe de flèche en os de la période mérovingienne découverte en Alsace Lors d’une fouille d’archéologie préventive réalisée en 2014 à Merxheim (dép. Haut-Rhin / F), un ensemble funéraire du haut Moyen Âge (6e - 10e siècles) a été mis au jour. Dans la sépulture 55, une pointe de flèche en os rattachée par sa forme à la période mérovingienne a été découverte. Lors de l’étude, aucun parallèle de pointe de flèche en os n’a été identifié dans le monde mérovingien. Il était donc nécessaire de comprendre cette absence de parallèles et les raisons qui ont poussé à façonner une pointe de flèche en os. La principale problématique était de savoir s’il y a pu avoir un intérêt balistique quelconque dans le choix de ce matériau, notamment pour la chasse au petit gibier. Pour ceci, les différents facteurs, de l’arc aux éléments constitutifs d’une flèche, ont été pris en compte. L’utilisation de l’os pour une pointe de flèche n’apparaît ainsi pas comme contre-indiquée. Cependant, l’absence de parallèles et la relative facilité de façonnage de ce type d’objet dans de l’os plutôt que dans du fer amènent également à envisager la probabilité d’un objet symbolique, dont le rôle aurait été de représenter la pratique de la chasse dans la sépulture.

description: We investigate similarities between non-deterministic and probabilistic ways of describing a system in terms of computation trees. We first show that the construction of traces for both kinds of relations follow the same principles of construction (which could be described in terms of monads, but this does not happen here). Finally representations of measurable trees in terms of probabilistic relations are given.

Hydrodynamization in kinetic theory: Transient modes and the gradient expansion

description: We explore the transition to hydrodynamics in a weakly-coupled model of quark-gluon plasma given by kinetic theory in the relaxation time approximation with conformal symmetry. We demonstrate that the gradient expansion in this model has a vanishing radius of convergence due to the presence of a transient (nonhydrodynamic) mode, in a way similar to results obtained earlier in strongly-coupled gauge theories. This suggests that the mechanism by which hydrodynamic behaviour emerges is the same, which we further corroborate by a novel comparison between solutions of different weakly and strongly coupled models. However, in contrast with other known cases, we find that not all the singularities of the analytic continuation of the Borel transform of the gradient expansion correspond to transient excitations of the microscopic system: some of them reflect analytic properties of the kinetic equation when the proper time is continued to complex values.

Embracing the Gray of Digital Preservation

description: Digital preservation is not a destination, but an on-going journey. As such, we need to take steps along that journey, no matter how imperfect, to at least attempt to preserve those objects entrusted to us. For too long we had been frozen on our journey at Ohio State, when confronted with born digital collections at scale; stuck in the binary of how do we describe these collections at the item level to ingest them into our existing digital perseveration repository, Digital Collections, or doing nothing at all. We had simply embraced the latter.

However, in the summer of 2021 we began to scheme the development of a lightweight, cloud-based digital preservation platform that could complement our existing digital preservation repo. One that would be based upon the archival principle of more product, less processing (MPLP). As we began to engage stakeholders, as well as architect, build and test the repository, we actually realized that this new repo was much more in alignment with our collecting and accessioning practices. We were essentially building a digital version of archival and special collections stacks. A digital preservation platform that contains minimally described objects that are tied to their finding aids, where they are discoverable by our users; while being stored in a secure space where only the curators can “wander” just like our secured stacks. Therefore, we have created a “gray” or “dim” repository, which is neither “light” (allows patron access) nor “dark” (essentially no access). Launched in January 2024, the Gray Digital Preservation Repository, is now our default repo for born digital content.

This poster will document the journey we have embarked upon, along with the workflow and tools, open source and proprietary, that we have used to build and sustain this new environment. While acknowledging the priviledge of our institution, we feel there are lessons learned from this journey that may benefit institutions of all sizes and resources.
Bestimmung c-optimaler Versuchspläne in Modellen mit zufälligen Effekten, mit Anwendungen in der Pharmakokinetik

description: Medizinische Studien im Bereich der Pharmakokinetik basieren in vielen Fällen auf speziellen Modellen mit zufälligen Effekten, den sogenannten Populationsmodellen. In solchen Studien werden jeweils mehrere Messungen an einer Anzahl verschiedener Patienten durchgeführt. Aus dem Blickwinkel der optimalen Versuchsplanung führt dies zu methodischen Schwierigkeiten, da der zufällige Effekt sowohl eine parameterabhängige Varianz der Beobachtungen als auch teilweise korrelierte Daten zur Folge hat. Auf diese Weise sind zwei der Schlüsselannahmen klassischer Versuchsplanungsliteratur verletzt. Es ist das Ziel dieser Arbeit, die bestehende Methodik so anzupassen und zu ergänzen, dass auch diese Situationen betrachtet werden können. Da die wichtigsten zu schätzenden Kenngrößen in der Pharmakokinetik bestimmte Summengrößen der Parameter sind (z.B. die Fläche unter der Konzentrationskurve eines Präparates) wird der Schwerpunkt dieser Arbeit auf c-optimalen Designs liegen, die die optimale Schätzung solcher Größen erlauben. Im einzelnen wird zunächst die geometrische Repräsentation optimaler Designs nach Elfving (1952) so verallgemeinert, dass die beschriebene Situation abgedeckt ist. Im zweiten Schritt wird die Äquivalenztheorie nach Kiefer (1974) und Pukelsheim (1993) auf das spezifische Modell angewendet. Dritter Schritt ist die Anpassung multplikativer Algorithmen zur numerischen Bestimmung optimaler Designs in dieser Situation, und als letztes Ergebnis wird das Konzept asymptotisch optimaler Designs auf einen speziellen Fall korrelierter Beobachtungen angewendet.

description: Einer oder zwei? Ein Stabgürtelhaken der Form Traunstein vom Gräberfeld Brzyno, Fundplatz 7 (woj. pomorskie / PL) In einem Brandgrab der Oksywie-Kultur im Gräberfeld von Brzyno, Fpl. 7 wurde ein Gürtelhaken der Form Traunstein aus Bronze entdeckt. Nach der Restaurierung zeigte sich, dass das Stück repariert worden war. Aller Wahrscheinlichkeit nach wurde dafür eine zweite derartige Schließe desselben Typs verwendet. Diese Annahme wird gestützt von Spuren auf dem Objekt selbst, aber auch durch metallkundliche Analysen. Die Beobachtung bezeugt, dass derartige prestigeträchtige Bestandteile der Frauentracht in Pommern häufiger verwendet wurden als bislang angenommen. Ferner scheint die Kenntnis von solchen importierten Gürtelhaken einheimische Schmiede zur Fertigung ähnlicher Gürtelschließen inspiriert zu haben. Den Rahmen dafür bildeten überregionale Kontakte mit Mitteldeutschland, die für die Phasen A2 und A3 erkennbar sind.
