In dieser Arbeit wurde der Frage nachgegangen, ob der Arbeitgeber nach ausgewählten Impfungen fragen darf bzw. unter welchen Umständen der Bewerber von sich aus seinen Impfstatus offenlegen muss. Bei den ausgewählten Impfungen handelt es sich um die FSME-Impfung, die Grippeimpfung, die Corona-Impfung und die Masernimpfung. Um hier zu einem Ergebnis zu kommen, wurde ein Überblick über das Fragerecht und die Offenbarungspflicht sowie deren Grenzen gegeben. Mit den daraus gewonnenen Erkenntnissen wurde im Hauptteil dieser Arbeit untersucht, ob der Bewerber ein Geheimhaltungsinteresse hinsichtlich seines Impfstatus hat und ob der Arbeitgeber ein sachliches Interesse am Impfstatus des Bewerbers haben kann. Im letzten Teil der Arbeit wurde anhand der vorstehenden Ergebnisse beurteilt, ob die jeweilige Frage zulässig ist oder nicht. eingereicht von Felix Paul Langergraber Diplomarbeit Universität Linz 2023 Arbeit auf den öffentlichen PCs in den Bibliotheken der JKU+Medizin abrufbar

We numerically study QCD with a single quark flavour on the lattice probing predictions from effective field theories that are equivalent to minimal super-symmetric Yang-Mills theory in the large $N_c$ limit. The hadronic spectrum including excited states is analysed using one gauge coupling and several physical volumes and fermion masses. We use the LapH method and also compute disconnected diagrams. Lattice simulations with an odd number of Wilson fermions give rise to regions of configuration space with a negative fermionic weight entailing a sign problem. We perform a detailed analysis on the spectrum of the Wilson-Dirac operator and report on observed cases of a negative fermion determinant in our ensembles., 9 pages, 10 figures

24th International Spin Symposium, SPIN2021, Matsue, Japan, 18 Oct 2021 - 22 Oct 2021; JPS conference proceedings 37, 021104 (2022). doi:10.7566/JPSCP.37.021104, In recent years, Laser Plasma Acceleration (LPA) has become a promising alternative toconventional RF accelerators. However, so far, it has only been theoretically shown thatgenerating polarized LPA beams is possible. The LEAP (Laser Electron Acceleration withPolarization) project at DESY aims to demonstrate this experimentally for the first time,using a pre-polarized plasma target.The electron polarization will be measured with photon transmission polarimetry, whichmakes use of the production of circularly polarized bremsstrahlung during the passage ofthe electron beams through a suitable converter target. The photon polarization is thenmeasured with the aid of transmission asymmetry arising from reversing the magnetizationdirection of an iron absorber.In this contribution an overview of the LEAP project is presented, detailing the generation ofthe polarized electron beams along with the design and simulation studies of the polarimeter., Published by The Physical Society of Japan, Tokyo

In this work, we address the challenge of developing statistical shape models that account for the non-Euclidean nature inherent to (anatomical) shape variation and at the same time offer fast, numerically robust processing and as much invariance as possible regarding translation and rotation, i.e. Euclidean motion. With the aim of doing that we formulate a continuous and physically motivated notion of shape space based on deformation gradients. We follow two different tracks endowing this differential representation with a Riemannian structure to establish a statistical shape model. (1) We derive a model based on differential coordinates as elements in GL(3)+. To this end, we adapt the notion of bi-invariant means employing an affine connection structure on GL(3)+. Furthermore, we perform second-order statistics based on a family of Riemannian metrics providing the most possible invariance, viz. GL(3)+-left-invariance and O(3)-right-invariance. (2) We endow the differential coordinates with a non-Euclidean structure, that stems from a product Lie group of stretches and rotations. This structure admits a bi-invariant metric and thus allows for a consistent analysis via manifold-valued Riemannian statistics. This work further presents a novel shape representation based on discrete fundamental forms that is naturally invariant under Euclidean motion, namely the fundamental coordinates. We endow this representation with a Lie group structure that admits bi-invariant metrics and therefore allows for consistent analysis using manifold-valued statistics based on the Riemannian framework. Furthermore, we derive a simple, efficient, robust, yet accurate (i.e. without resorting to model approximations) solver for the inverse problem that allows for interactive applications. Beyond statistical shape modeling the proposed framework is amenable for surface processing such as quasi-isometric flattening. Additionally, the last part of the thesis aims on shape-based, continuous disease stratification to provide means that objectify disease assessment over the current clinical practice of ordinal grading systems. Therefore, we derive the geodesic B-score, a generalization of the of the Euclidean B-score, in order to assess knee osteoarthritis. In this context we present a Newton-type fixed point iteration for projection onto geodesics in shape space. On the application side, we show that the derived geodesic B-score features, in comparison to its Euclidean counterpart, an improved predictive performance on assessing the risk of total knee replacement surgery., Die vorliegende Arbeit beschäftigt sich mit der Herausforderung der Entwicklung statistischer Formmodelle, welche die inhärente nichteuklidische Struktur (anatomischer) Formvariation berücksichtigen, gleichzeitig eine effiziente, numerisch robuste Verarbeitung erlauben und zusätzlich möglichst viel Invarianz unter euklidischen Bewegungen der verwendeten Daten bieten. Dazu schlagen wir einen kontinuierlichen und physikalisch motivierten Formenraum basierend auf Deformationsgradienten vor. Wir verfolgen zwei verschiedene Ansätze, um auf diesem eine Riemannsche Struktur und damit ein statistisches Formmodell zu etablieren. (1) Wir entwickeln ein Modell für die differentiellen Koordinaten als Elemente in GL(3)+. Zu diesem Zweck adaptieren wir den Begriff des biinvarianten Mittelwerts bezüglich eines affinen Zusammenhanges auf GL(3)+ und führen Statistik zweiter Ordnung basierend auf einer Familie maximal invarianter, d.h. GL(3)+-links- und O(3)-rechts-invarianter, Riemannscher Metriken durch. (2) Wir versehen die differentiellen Koordinaten mit einer nichteuklidischen Struktur, die angelehnt an die Lie-Produktgruppe aus Streckungen und Rotationen ist. Diese lässt eine biinvariante Metrik und damit eine konsistente Analyse mittels mannigfaltigkeitswertiger Statistik im Riemannschen Rahmen zu. Die vorliegende Arbeit präsentiert überdies die fundamentalen Koordinaten, eine neue Formrepräsentation basierend auf diskreten Flächenfundamentalformen, welche auf natürliche Weise invariant unter euklidischen Bewegungen ist. Wir versehen diese Repräsentation mit einer Lie-Gruppenstruktur, die eine biinvariante Metrik und somit Riemannsche Statistik erlaubt. Darüber hinaus entwickeln wir einen einfachen, effizienten, robusten, sowie akkuraten (d.h. ohne Rückgriff auf Modellapproximationen) Löser für die Rückabbildung von den Koordinaten zur Form im Raum. Neben der statistischen Formanalyse erlaubt der beschriebene Ansatz auch Anwendungen in der Geometrieverarbeitung, insbesondere zur quasi-isometrischen Oberflächenverflachung. Der letzte Abschnitt der Arbeit befasst sich mit der Entwicklung kontinuierlicher formbasierter Erkrankungsstratifikationen, um die Krankheitsbewertung über die aktuelle klinische Praxis ordinaler Bewertungssysteme hinaus zu objektivieren. Hierzu entwickeln wir den geodesic B-score in gekrümmten Formenräumen zur Bewertung von Kniegelenksarthrose als Generalisierung des euklidischen B-scores. In diesem Rahmen beschreiben wir eine Newton-Typ-Fixpunktiteration zur Bestimmung der Projektion auf Geodätische im Formenraum. Als Anwendung zeigen wir, dass der geodätische B-score gegenüber seinem euklidischen Gegenstück eine verbesserte Vorhersageleistung hinsichtlich der Risikobewertung bezüglich einer totalen Kniearthroplastie besitzt.

As part of the 2019 Southern oCean seAsonal Experiment (SCALE) Winter Cruise of the South African icebreaker SA Agulhas II first-year ice was sampled at the advancing outer edge of the Antarctic marginal ice zone along a 150 km-Good Hope Line transect. Ice cores were extracted from four solitary pancake ice floes of 1.83–2.95 m diameter and 0.37–0.45 m thickness as well as a 12 × 4 m2 pancake ice floe of 0.31–0.76 m thickness part of a larger consolidated pack ice domain. The ice cores were subsequently analyzed for temperature, salinity, texture, anisotropic elastic properties and compressive strength. All ice cores from both, solitary pancake ice floes and consolidated pack ice, exhibited predominantly granular textures. The vertical distributions of salinity, brine volume and mechanical properties were significantly different for the two ice types. High salinity values of 12.6 ± 4.9 PSU were found at the topmost layer of the solitary pancake ice floes but not for the consolidated pack ice. The uniaxial compressive strength for pancake ice and consolidated pack ice were determined as 2.3 ± 0.5 MPa and 4.1 ± 0.9 MPa, respectively. The Young’s and shear moduli in longitudinal core direction of solitary pancake ice were obtained as 3.7 ± 2.0 GPa and 1.3 ± 0.7 GPa, and for consolidated pack ice as 6.4 ± 1.6 GPa and 2.3 ± 0.6 GPa, respectively. Comparing Young’s and shear moduli measured in longitudinal and transverse core directions, a clear directional dependency was found, in particular for the consolidated pack ice.

[EN] Sea ice growth in the Marginal Ice Zone of the Antarctic is one of the largest annual changes on earth with a huge impact on the global climate and ecology system. The principles of sea ice growth and melting in the MIZ of the Antarctic is yet not as well researched as its polar counterpart in the north.For this study, pancake ice, consolidated ice and floe ice were analyzed with a compression test in July, October and November 2019 in the marginal ice zone of the Antarctic. Newly formed pancake ice in July showed the highest compressive strength in the bottom layer (3 MPa), whereas consolidated ice was strongest at the top (5 MPa). Consolidated ice in October and November had the highest compressive strength in a middle layer with up to 13.5 MPa, the maximum strength at the top was 3 MPa. Floe ice, consisting of destroyed pack ice, did not show a clear strength development over sea ice depth., The SCALE cruises are funded by the South African National Research Foundation (NRF) through the South African National Antarctic Programme (SANAP), with contributions from the Department of Science and Innovation and the Department of Environmental Affairs. We are very grateful to the teams that have contributed to the success of the SCALE cruise in particular under the guidance of Marcello Vichi and J¨org Schröder.

Frazil ice, consisting of loose disc-shaped ice crystals, is the very first ice that forms in the annual cycle in the marginal ice zone (MIZ) of the Antarctic. A sufficient number of frazil ice crystals forms the surface grease ice layer taking a fundamental role in the freezing processes in the MIZ. As soon as the ocean waves are sufficiently damped, a closed ice cover can form. In this brief communication we investigate the rheological properties of frazil ice, which has a crucial influence on the growth of sea ice in the MIZ. Grease ice shows shear thinning flow behavior.

In this thesis we study strongly correlated quantum systems in extreme temperature and density conditions. A prominent example is the quark-gluon plasma produced in ultra- relativistic heavy-ion collisions. Since the degrees of freedom in the systems of interest are strongly coupled the use of non-perturbative methods is required. Our working method is lattice field theory allowing for high precision ab-initio calculations of physical quan- tities based on Monte Carlo simulations. We study QCD-like theories at finite density. This introduces the sign problem to the lattice preventing the applicability of importance sampling algorithms. Promising methods to tackle the sign problem are the Complex Langevin evolution on the one hand and Lefschetz Thimbles on the other hand. In this work we propose novel algorithmic ideas to both approaches which are put to work in simple models with a sign problem as well as in lattice gauge theories. Moreover, we in- vestigate real-time properties of quantum systems at finite temperature which is necessary for the computation of transport coefficients. To that end we conduct lattice simulations in imaginary time which are aimed at improving the spectral reconstruction of thermal features. Moreover, we study simulations directly in real-time by means of the Complex Langevin evolution equipped with variable transformations.

In this work, the complex structure of ionization and dissociation pathways on the potential energy curves in small molecules were investigated that are initiated by the absorption of a sequence of multi-color pulses in the XUV, VUV, and IR spectrum. Femtosecond pump-probe spectroscopy was used to track the evolution of nuclear dynamics in neutral hydrogen molecules. Previously unpublished excitation and ionization pathways leading to the dissociative ionization of hydrogen molecules were investigated by employing 3D momentum imaging spectroscopy. These studies were extended to oxygen molecules where an XUV attosecond pulse train coherently ionized several electronic states of O2+ followed by the dissociation of the molecule via multiple pathways. The infrared electric field of the driving laser was then used to couple the electronic and nuclear wave-packets, thus, manipulating the dissociation dynamics of the molecule on an attosecond time scale. In order to perform the experiments presented here, a novel experimental setup was developed and constructed. It combines an existing high-flux High Harmonic Generation light source that delivers attosecond pulse trains in the VUV and XUV spectrum with a state-of-the-art 3D momentum imaging apparatus (COLTRIMS), as well as a beamline consisting of several experimental tools enabling the selection, characterization, and propagation of the photon spectrum.

A combination of mesenchymal stem cells (MSCs) and scaffolds seems to be a promising approach for meniscus repair. To facilitate the search for an appropriate scaffold material a reliable and objective in vitro testing system is essential. This paper introduces a new scoring for this purpose and analyzes a hyaluronic acid (HA) gelatin composite scaffold and a polyurethane scaffold in combination with MSCs for tissue engineering of meniscus. The pore quality and interconnectivity of pores of a HA gelatin composite scaffold and a polyurethane scaffold were analyzed by surface photography and Berliner-Blau-BSA-solution vacuum filling. Further the two scaffold materials were vacuum-filled with human MSCs and analyzed by histology and immunohistochemistry after 21 days in chondrogenic media to determine cell distribution and cell survival as well as proteoglycan production, collagen type I and II content. The polyurethane scaffold showed better results than the hyaluronic acid gelatin composite scaffold, with signs of central necrosis in the HA gelatin composite scaffolds. The polyurethane scaffold showed good porosity, excellent pore interconnectivity, good cell distribution and cell survival, as well as an extensive content of proteoglycans and collagen type II. The polyurethane scaffold seems to be a promising biomaterial for a mesenchymal stem cell-based tissue engineering approach for meniscal repair. The new score could be applied as a new standard for in vitro scaffold testing.

Die Abhängigkeit des Alveolarknochens von der Präsenz der Zähne und die entsprechend komplexe knöcherne Struktur des Alveolarfortsatzes sind allgemein bekannt. Schon vor der Eruption besteht eine enge Beziehung zwischen den sich entwickelnden Zahnanlagen und dem sie umgebenden Knochen. Über die genaue pränatale Entwicklung des Knochens im Bereich der Zahnanlagen und die räumliche Anordnung der beteiligten Strukturen ist allerdings wenig bekannt. Intensiver untersucht ist dagegen die molekulare Steuerung des Knochenumbaus im sogenannten Tooth-Bone-Interface. Jedoch stößt die Fülle der entdeckten Faktoren auf eine mangelnde räumliche Zuordnung. Erst durch die dreidimensionale Darstellung können morphologisch bedeutsame Wachstumsvorgänge untersucht werden. In diesem Zusammenhang stellte sich die Frage nach der morphologischen Entwicklung des Kieferknochens während der Zahnentwicklung. Hierfür wurde im Rahmen des Projektes „Interaktionen zwischen Zahnanlage und Kieferknochen bei der Bildung des Alveolarfortsatzes“ die menschliche Mandibula anhand von 14 Schnittserien von Feten der Scheitel-Steiß-Länge (SSL) 68 bis 160 mm (Glockenstadium der Zahnentwicklung) mikroskopisch untersucht. Davon wurden vier Schnittserien exemplarisch mit Hilfe der Software AnalySIS® dreidimensional rekonstruiert, der Knochen im Bereich der Zahnanlagen histomorphologisch auf Knochenumbauvorgänge (Resorptions-, Appositions- und Ruhezonen) untersucht sowie systematische Abstandsmessungen durchgeführt. Die ermittelten Ergebnisse führen zu folgenden Schlussfolgerungen: 1\. Die Zahnanlagen entwickeln sich in knöchernen Krypten: Bereits pränatal besteht eine ausgeprägte Beziehung zwischen Zahnanlagen und Knochen. Diese unterscheidet sich strukturell zu den Verhältnissen im späteren Alveolarfortsatz. Da der Alveolarknochen und das Desmodont noch nicht gebildet sind, muss nomenklatorisch differenziert werden: Die Zahnentwicklung findet nicht in den Alveolen des Aleolarfortsatzes statt, sondern es bildet sich an der Mandibula zunächst eine knöcherne Rinne, welche die Zahnanlagen im Laufe der Entwicklung zunehmend umgibt, bis schließlich jeweils eine knöcherne Krypte entsteht. Diese bleiben bis zur SSL von 160 mm (18. Woche) unvollständig. Die labiale knöcherne Begrenzung der Milcheckzahnanlage fehlt in allen untersuchten Stadien. Mesial und distal dieser Anlage entstehen hingegen die ersten knöchernen Septen. Die Milchmolaren- und Milchschneidezahnkeime entwickeln sich jeweils in einem gemeinsamen Kompartiment, in welchem eine unvollständige Separation in Form von Knochenvorsprüngen, Knochenfortsätzen und Knochengraten zu erkennen ist. 2\. Die Zahnanlagen senken sich in den Kieferknochen ein: Die knöchernen Krypten wachsen zentrifugal durch ein Zusammenspiel aus Knochenapposition und -resorption. Unterhalb der Zahnanlage finden intensive Knochenresorptionsvorgänge statt, vorzugsweise dort, wo der Abstand zwischen wachsender Zahnanlage und Mandibula geringer wird. An den Außenseiten der Krypten sowie marginal findet appositionelles Knochenwachstum statt. Knöcherne Septen sind ebenfalls Ergebnisse aktiven Knochenwachstums, wobei sie einem intensiven Umbau unterliegen. 3\. Anteile der knöchernen Krypte entstehen durch chondrale Ossifikation: Der Kieferknochen im Bereich der Zahnanlagen weist alle drei Formen der Knochenbildung auf. Hauptsächlich findet desmale Ossifikation statt. Durch perichondrale Ossifikation des Meckelschen Knorpels bilden sich große Teile des Knochens lingual sowie kaudal der Zahnanlagen. Außerdem entwickelt sich an einigen Stellen sekundärer Knorpel in unmittelbarer Nähe der Zahnanlagen. Diese Anteile der Krypte sind vom Meckelschen Knorpel unabhängig und ossifizieren enchondral. 4\. Der Kieferknochen entwickelt sich samt knöcherner Krypten als zusammenhängendes Gebilde: Separate knöcherne Anteile, die sich aus dem Zahnsäckchen bilden, sind nicht zu erkennen. Das Zahnsäckchen lässt sich innerhalb der Zahnanlage erst ab dem Glockenstadium topografisch und histologisch vom verdichteten Ektomesenchym differenzieren. Es umschließt in konzentrischen, kollagenreichen Lagen Schmelzorgan und Papille, wird zunehmend filigraner und ist schließlich kaum mehr zu erkennen. Die vorliegenden 3D-Modelle mit Charakterisierung der Knochenoberfläche entsprechend des Umbauverhaltens bilden die Grundlage für weiterführende Untersuchungen zur Ermittlung mechanischer und molekulargenetischer Abhängigkeiten der Knochenbildung und des Knochenumbaus während der Zahnentwicklung., The dependence of the alveolar bone to the presence of teeth and the corresponding complex bony structure of the alveolar bone are well known. Even before the eruption of teeth, there is a close relationship between the developing tooth germs and surrounding bone. However, little is known about the exact prenatal development of the surrounding bone and the spatial arrangement of involving structures. In comparison, the molecular regulation of bone remodeling within the so-called tooth-bone-interface has been studied intensively. However, although there is an abundance of identified factors on the aforementioned area, unfortunately, there is still a lack of examination of spatial association. Only through three-dimensional reconstructions it is possible to examine the important morphological growth processes that occur. Within this context, the morphological development of the jaws during tooth development is of high interest. Over the course of the project "Interactions between tooth germs and jaw during formation of alveolar process" the human mandible was examined microscopically in 14 serial sections of fetuses of crown-rump-length (CRL) 68 to 160 mm (bell stage of the tooth development). Four representative serial sections of these were reconstructed three- dimensionally using the software AnalySIS®. The bone was studied histologically on bone modeling processes (resorption, apposition and resting areas) and systematic distance measurements were conducted. The results obtained lead to the following conclusions: 1\. The tooth germs develop in bony crypts: There is a pronounced relationship between tooth germs and bone already in prenatal stages, but it differs structurally from the conditions in future alveolar process. Alveolar bone and periodontal ligament are not formed yet. Therefore, a differentiated nomenclature should be used. The tooth development does not take place in the alveoli of the alveolar process. First it starts with the formation of a bony groove in the mandible, which surrounds the tooth germs increasingly during development, until finally each one gets a bony crypt. They remain incomplete until CRL of 160 mm (18th week). The labial bony wall of the crypt of the deciduous canine germ is missing in all examined stages. But mesial and distal to this germ arise the first bony septa. The deciduous molar and incisor germs develop each in a common compartment in which is recognizable an incomplete separation in form of bony protuberances, bony processes and bone ridges. 2\. The tooth germs lower into the jaw: The bony crypts grow centrifugally through a combination of bone apposition and resorption. Below the tooth germs intensive bone resorption takes place, particularly where the distance between growing tooth germ and mandible gets reduced. Appositional bone growth takes place on the outer sides of the crypts and marginal. Bony septa are also results of active bone growth, though they undergo extensive remodeling. 3\. Some parts of the bony crypt arise from chondral ossification: The tooth germs surrounding bone shows all three types of bone formation, although this bone occurs primarily through intramembranous ossification. Large parts of the bone lingual and caudal to the tooth germs are formed by perichondral ossification of Meckel's cartilage. In addition, in some places secondary cartilages develop in close vicinity to the tooth germs. These parts of the crypt are independent of the Meckel's cartilage and ossify endochondrally. 4\. The jaw with its bony crypts develops as a coherent entity: Separate bony parts, which arise from the dental follicle, are not visible. The dental follicle can be differentiated topographically and histologically from dense ectomesenchyme only at the beginning of bell stage. It encloses in concentric and collagen-rich layers enamel organ and papilla, becoming increasingly intricate, and finally is hardly recognizable. These present 3D-models with the characterization of bone surface according to bone remodeling form the basis for further studies especially determining mechanical and molecular genetic dependencies of bone formation and bone remodeling during tooth development.

A cellular construction, in particular a supporting or sound insulating construction capable of being greened, is filled with earth, rocks or bulk materials (EG) in cells (Z) arranged in particular in layers. The cells are at least partially delimited by a flexible, liquid-permeable, in particular net or grid-like flat material (F) and have at least one dimensionally stable, grid-like front element (F) connected to an anchoring tie (ZA) which is also made of a net or grid-like flat material and extends into the cell filling material. The grid-like front element (F) is also connected to an anchoring prop (ZV) which ensures the predetermined front inclination and front position of the construction. The anchoring prop (ZV) for the individual front elements has at least one elongated anchoring member (AS) with one end connected to a front element (FG) and another end that extends into the filling material. The cellular construction is characterised in that traction forces are transmitted only through the flat material (F) in the area of an anchoring prop (ZV), between the connection point (K1) of the anchoring tie flat material (F) to the anchoring prop (ZV) on the one hand and the connection point (K2) of said flat material (F) to the front element (FG) on the other hand.

El presente trabajo de investigación tiene por objetivo mejorar el proceso de priorización de las inversiones en saneamiento rural que realiza el sector saneamiento, hecho que generará eficiencia en el gasto público. Para lo cual, se revisa información referente a las inversiones en materia de saneamiento rural que viene realizando el Ministerio de Vivienda Construcción y Saneamiento, analizando los avances en mejora de cobertura, así como su evaluación en el cumplimiento de lo programado en el Plan Nacional de Saneamiento 2017-2021. Como resultado, se verifica que las inversiones hechas por el sector en infraestructura de saneamiento rural durante los años 2017 al 2019 son insuficientes para el cumplimiento de las metas incluidas en el Plan Nacional. De esta manera, se concluye que la implementación de los procesos de priorizacón presentan deficiencias, recomendándose actualizar el DATASS, instrumento que permite un diagnóstico certero del estado de los servicio. Asimismo, se propone la repotenciación de las oficinas desconcertadas y el aprovechamiento de la información técnica que se cuenta de los 281 expedientes aprobados en la PRESET (Plataforma de Registro, Evaluación y Seguimiento de Expedientes Técnicos), en diferentes regiones del país.

El trabajo tiene como objetivo identificar los puntos críticos y posibilidades de mejora en el proceso de asignación del Bono Familiar Habitacional, a través del programa Techo Propio, perteneciente al Fondo Mivivienda, que busca que los peruanos puedan acceder a una vivienda digna con la participación del promotor inmobiliario y constructor. En tanto, se evidencia que existen grupos familiares que demuestran, luego de recepcionar sus viviendas, que no encajan en el perfil establecido por el Programa en mención. La revisión de documentos oficiales y entrevistas confirman un vacío legal que no penaliza la no recepción inmediata por parte de los beneficiarios, ocasionando perjuicios económicos a las empresas constructoras, así como el no aprovechamiento por parte de otra familia que necesite de la misma. De la información recogida del trabajo de campo, se encontó que el 11% de los beneficiarios no han recepcionado sus viviendas o hicieron modificaciones en las mismas. Asimismo, se demuestra que parte del proceso de asignación consiste en la revisión de la información presentada por el postulante en plataformas del Estado como: SUNARP, SUNAT y RENIEC; sin embargo, estos filtros son insuficientes en algunos casos, ya que no permite revisar el perfil financiero de las personas que postulan. Por lo que, se recomienda incluir un seguimiento post-entrega de los grupos beneficiados, teniendo como objetivo corroborar el nivel socioeconómico declarado. Trabajo de investigación
