description: The category of locally compact quantum groups can be described as either Hopf $*$-homomorphisms between universal quantum groups, or as bicharacters on reduced quantum groups. We show how Sołtan's quantum Bohr compactification can be used to construct a ``compactification'' in this category. Depending on the viewpoint, different C$^*$-algebraic compact quantum groups are produced, but the underlying Hopf $*$-algebras are always, canonically, the same. We show that a complicated range of behaviours, with C$^*$-completions between the reduced and universal level, can occur even in the cocommutative case, thus answering a question of Sołtan. We also study such compactifications from the perspective of (almost) periodic functions. We give a definition of a periodic element in $L^\infty(\mathbb G)$, involving the antipode, which allows one to compute the Hopf $*$-algebra of the compactification of $\mathbb G$; we later study when the antipode assumption can be dropped. In the cocommutative case we make a detailed study of Runde's notion of a completely almost periodic functional-- with a slight strengthening, we show that for [SIN] groups this does recover the Bohr compactification of $\hat G$.

description: Water splitting to give molecular oxygen and hydrogen or the corresponding protons and electrons is a fundamental four-electron redox process, which forms the basis of photosynthesis and is a promising approach to convert solar into chemical energy. Artificial water splitting systems have struggled with orchestrating the kinetically complex absorption of four photons as well as the difficult utilization of visible light. Based on a detailed kinetic, spectroscopic and computational study of Milstein's ruthenium complex, we report a new mechanistic paradigm for water splitting, which requires only two photons and offers a new method to extend the range of usable wavelengths far into the visible region. We show that two-photon water splitting is enabled by absorption of the first, shorter wavelength photon, which produces an intermediate capable of absorbing the second, longer wavelength photon (up to 630 nm). The second absorption then causes O–O bond formation and liberation of O2. Theoretical modelling shows that two-photon water splitting can be used to achieve a maximum solar-to-hydrogen efficiency of 18.8%, which could be increased further to 28.6% through photochemical instead of thermal H2 release. It is therefore possible to exceed the maximum efficiency of dual absorber systems while only requiring a single catalyst. Due to the lower kinetic complexity, intrinsic utilization of a wide wavelength range and high-performance potential, we believe that this mechanism will inspire the development of a new class of water splitting systems that go beyond the reaction blueprint of photosynthesis.

description: Evolution operators of certain quantum walks possess, apart from the continuous part, also point spectrum. The existence of eigenvalues and the corresponding stationary states lead to partial trapping of the walker in the vicinity of the origin. We analyze the stability of this feature for three-state quantum walks on a line subject to homogenous coin deformations. We find two classes of coin operators that preserve the point spectrum. These new classes of coins are generalizations of coins found previously by different methods and shed light on the rich spectrum of coins that can drive discrete-time quantum walks.
Depolarization of multiple scattered light in atmospheres due to anisotropy of small grains and molecules

description: Freely oriented small anisotropic grains and molecules depolarize radiation both in single scattering and in the process of multiple scattering. Especially large depolarization occurs for resonant scattering corresponding to the electron transitions between the energy levels with very different quantum numbers. The existence of light absorption also changes essentially the angular distribution and polarization of radiation, outgoing from an atmosphere. In the present paper we consider these effects in detail both for continuum radiation and for resonant lines. Because the term describing the depolarization deals with isotropic radiation, we consider the axially symmetric part of radiation. We derived the formulas for observed intensity and polarization using the invariance-principles both for continuum and resonant scattering. We confine ourselves to two problems - the diffuse reflection of the light beam from semi-infinite atmosphere, and the Milne problem.

title: Des interventions didactiques systémiques en réponse aux conflits sociolinguistiques : quelles dynamiques et (r)évolutions à Berne ?

description: Ancrés en didactique des langues et des cultures (DLC), nos travaux sur le rapport au français des étudiants de la Pädagogische Hochschule (PHBern) ont notamment permis de confirmer que de nombreux futurs enseignants germanophones du primaire présentent des résistances à l’encontre d’un de leurs futurs objets d’enseignement: cette langue dite « étrangère » dans les plans d’études alémaniques. Toutefois, les expériences de mobilité imposées en région francophone se révèlent être un lieu-pivot potentiel du rapport au français au sein de la formation initiale.  La formation a récemment fait peau neuve. S’appuyant sur les approches socio-anthropologiques, un dispositif systémique de « didactique de la mobilité » articule désormais contexte social, besoins du public en formation, pratiques réflexives et travail sur les représentations sociales. En parallèle, les Relations Internationales de la PHBern se dotent d’un dispositif de préparation, accompagnement et réinvestissement des semestres d’échange académiques. De plus, deux projets de formation bilingue français-allemand sont actuellement à l’étude : l’administration scolaire communale travaille à la conception de classes bilingues et la Haute École Pédagogique francophone et la PHBern créent conjointement une formation initiale bilingue des enseignants du primaire.  À des niveaux variés du domaine éducatif, on voit ainsi des institutions bernoises proposer des projets apparemment favorables au français, au bilinguisme et au rapport entre les communautés linguistiques cantonales. Quels fondements théoriques et quelles dynamiques liées aux langues, à leurs statuts et à leurs enjeux se cachent derrière ces projets? Les traditionnelles conceptions institutionnelles de la mobilité et du rapport à l’altérité auraient-elles évolué?

Gravitational entropies in LTB dust models

description: We consider generic Lemaitre-Tolman-Bondi (LTB) dust models to probe the gravitational entropy proposals of Clifton, Ellis and Tavakol (CET) and of Hosoya and Buchert (HB). We also consider a variant of the HB proposal based on a suitable quasi-local scalar weighted average. We show that the conditions for entropy growth for all proposals are directly related to a negative correlation of similar fluctuations of the energy density and Hubble scalar. While this correlation is evaluated locally for the CET proposal, it must be evaluated in a non--local domain dependent manner for the two HB proposals. By looking at the fulfillment of these conditions at the relevant asymptotic limits we are able to provide a well grounded qualitative description of the full time evolution and radial asymptotic scaling of the three entropies in generic models. The following rigorous analytic results are obtained for the three proposals: (i) entropy grows when the density growing mode is dominant, (ii) all ever-expanding hyperbolic models reach a stable terminal equilibrium characterized by an inhomogeneous entropy maximum in their late time evolution; (iii) regions with decaying modes and collapsing elliptic models exhibit unstable equilibria associated with an entropy minimum (iv) near singularities the CET entropy diverges while the HB entropies converge; (v) the CET entropy converges for all models in the radial asymptotic range, whereas the HB entropies only converge for models asymptotic to an FLRW background. The fact that different independent proposals yield fairly similar conditions for entropy production, time evolution and radial scaling in generic LTB models seems to suggest that their common notion of a "gravitational entropy" may be a theoretically robust concept applicable to more general spacetimes.

description: We numerically construct asymptotically anti-de Sitter boson star solutions using a minimally coupled $\frac{D-1}{2}$-tuplet complex scalar field in $D=5,7,9,11$ dimensions. The metric admits multiple Killing vector fields in general, however the scalar fields are only invariant under a particular combination, leading to such boson star solutions possessing just a single helical Killing symmetry. These boson stars form a one parameter family of solutions, which can be parametrized by the energy density at their center. As the central energy density tends to infinity, the angular velocity, mass, and angular momentum of the boson star exhibit damped harmonic oscillations about finite central values, while the Kretschmann invariant diverges, signaling the formation of a black hole in this limit.

description: Decisions in the context of Climate Engineering (CE), the deliberate large-scale manipulation of the Earth’s climate, are decisions made under uncertainty. CE options are associated with a broad range of environmental and societal risks that raise complex questions: How can the risks be assessed and evaluated when balanced against the risks of alternative strategies to counteract climate change? What are the strategic implications for climate politics against the background of insufficient scientific knowledge? Can we estimate the ethical implications of the risks involved for society? Uncertainties and risks represent a central aspect of the issue but cannot be reduced to the traditional technical orientation of risk terminologies. The article elaborates on the specific characteristics of the risks and uncertainties associated with CE technology from six different disciplinary viewpoints. It thereby seeks to reveal chances for a mutual enrichment of these individual viewpoints since each discipline experiences boundaries while examining the complex risks of CE. In this way, the article redefines disciplinary boundaries without entirely dissolving them and without disregarding the valuable contribution every individual viewpoint can make. This aim is realized by means of the identification of new approaches to central questions regarding the risks and uncertainties involved in CE that can only be addressed from an interdisciplinary perspective.

description: Erzählungen bilden einen großen Teil des Gegenstandsbereichs einer Fülle von Wissenschaften; neben den Sozialwissenschaften befassen sich etwa Philosophie, Geschichtswissenschaft, Anthropologie, Psychologie und Rechtswissenschaft mit Narrationen. Zudem hat sich in vielen Disziplinen die Einsicht durchgesetzt, dass die Form von Erzählungen maßgeblichen Einfluss auf die Bedeutung hat, die den erzählten Ereignissen zugewiesen wird. Der Artikel begründet die Relevanz einer interdisziplinären Auseinandersetzung mit dem Schlüsselkonzept der Narrativität anhand von drei Schritten: Zunächst erfolgt eine Begriffsdefinition, danach werden kurze Überlegungen zum interdisziplinären Potenzial der Erzähltheorie angestellt, und zum Schluss werden einige kognitive Funktionen von Erzählungen skizziert, wobei exemplarisch auf Empathie, ‚Theory of Mind‘ und die persuasive Kraft von Erzählungen eingegangen wird.

description: Über das Verhältnis von Natur- und Geisteswissenschaften wurde lange gestritten. Man sprach von zwei Kulturen, die gegeneinander relativ geschlossen seien. Sie hätten sich denn auch wechselseitig wenig zu sagen. Die einen strebten nach exakter Forschung, die anderen eher nach einer Form von Literatur.In dem Essay wird auf den historischen Ursprung der Scheidung zwischen Natur- und Geisteswissenschaften sowie dieser Stereotypen eingegangen. Zudem wird gezeigt, dass wir es heute nicht mit zwei, sondern mit vier Wissenschaftskulturen zu tun haben, die sich gegenseitig fordern. Das Gespräch zwischen ihnen zu ermöglichen, ist deshalb ein Desiderat. Am Beispiel des Verhältnisses der Neurowissenschaften zur Philosophie, hier verbunden mit den Namen John C. Eccles und Karl R. Popper, wird dargelegt, wie voraussetzungsvoll ein solches Gespräch ist, zu welchen interessanten Ergebnissen es aber kommen kann, wenn man neugierig aufeinander ist und die wechselseitige Stereotypierung überwindet. Das setzt freilich außer gutem Willen auch Klarheit in den verschiedenartigen wissenschaftstheoretischen Grundlagen moderner Forschung voraus.

description: We report on the direct observation of the transmission phase shift through a Kondo correlated quantum dot by employing a new type of two-path interferometer. We observed a clear $π/2$-phase shift, which persists up to the Kondo temperature $T_{\rm K}$. Above this temperature, the phase shifts by more than $π/2$ at each Coulomb peak, approaching the behavior observed for the standard Coulomb blockade regime. These observations are in remarkable agreement with 2-level numerical renormalization group calculations. The unique combination of experimental and theoretical results presented here fully elucidates the phase evolution in the Kondo regime.

description: Many of Miguel de Unamuno’s works probe the nature of reality and its boundaries within texts. This preoccupation with the control an author holds or loses over a text provides ample material for a deeper understanding of the complex prologic structure of his novel Niebla, including its various epitexts. This article contextualizes the ways in which the author approaches the reader and the positions that author and reader gain and switch regarding the medium. As the article shows, not only is it clear that the prologues are an integral part of the metafictional construct that Niebla is, but they are also apparent solutions that help explain the contradictions created when the authorship of the prologues turns out not to withstand the complexity of Unamuno's metafictional creation as a whole.

description: Alain Robbe-Grillet and Roland Barthes, two leading figures in post-war French literature and thought, both embark upon their respective projects from a state of semiotic alienation, encapsulated in the concept of écriture. Reality and language both appear governed by ideologically charged systems of signification; only the circumvention of this alienation may provide the means, however provisional, for any utterance to be able to reside beyond the given. Robbe-Grillet’s strategy consists of a return to the mute surface of things that seems to provide access to a reality prior to any imposition of meaning. Barthes’s strategy is more oblique. Despite his relentless critique of the alienating codes at work in quotidian and scientific discourses, his reflections on photography, which form a continual strand in his thinking, seem concerned with the conception of a non-coded access to reality, which photography appears capable of offering. In both cases, however, immediacy and meaning gradually reveal themselves as mutually exclusive. Robbe-Grillets Le miroir qui revient and Barthes’ La chambre claire, thus, both provide forms of discourse that try to negotiate this dilemma.

description: It has recently been noted that the relative prevalence of the various kinds of epistasis varies along an adaptive walk. This has been explained as a result of mean regression in NK model fitness landscapes. Here we show that this phenomenon occurs quite generally in fitness landscapes. We propose a simple and general explanation for this phenomemon, confirming the role of mean regression. We provide support for this explanation with simulations, and discuss the empirical relevance of our findings.

Such a space is unique, up to isometries, does contain an isometric copy of each separable $p$-Banach space and has the remarkable property of being "locally injective" amongst $p$-Banach spaces. We also present a nonseparable generalization which is of universal disposition for separable spaces and "separably injective". No separably injective $p$-Banach space was previously known for $p<1$.

Place value system

description: The ancient Greeks used their alphabet also as numerals, using an apostroph, acute accent or prime for the distinction. With α’ = 1 and β’ = 2 and ι’ = 10, then ια’ = 11 and βι’ = 12, since the value of the letters mattered and they did not have a place value system. The 1000s were denoted with the “hasta” (a subscript prime, U + 0375), with ͵α’ = 1000 and ͵β’ = 2000 etcetera. In Mathematica 13.1 the routine IntegerString translates Hindu-Arabic numbers into Greek, e.g. 1101 → ͵αρα´. There is no built-in inverse however. This is provided in the present package. There is the issue of using f ‘ = 6 or ς ‘ = 6. Latin letters might be used for ease of input. An application is the calculation of “the number of the beast” 666, as calculated by the Apostle John in the Book of Revelations. The “word value” of a name of a person can be determined via addition of the values of the separate letters, like Ζ’ + ε’ + υ’ + ς’ = 7 + 5 + 400 + 6 = 418.

description: The purpose of the study was to analyze the impacts of historical and future LULC change on hydrological components and optimal reservoir operations. The historical and future LULC scenarios were developed using the ERDAS Imagine model and Land Change Modeler respectively. In the watershed, the development of agricultural land and the reduction of forest cover were the major contributors to the increase in surface runoff and decline in groundwater flow. To model and optimize the operation of the Nashe hydropower reservoir, the SWAT model and the HEC-ResPRM optimization model were used.

description: This thesis examines the role of the Virgin’s cult at Le Puy amongst the major power struggles and quests for authority from 975 – 1229: through its role in the early Peace of God movement (975-1052), the Investiture Controversy (1056-1080), the First Crusade (1095-1100), the eleventh century Capetian expansion (1130-1182), the Capuchon movement (1182-1185), and the Albigensian Crusade (1209-1229). I draw on the field of border studies to illustrate how Le Puy’s location as a border territory amongst warring kingdoms resulted not only increased tumult but made it an attractive prize for the competing figures of authority in the period.

description: Causes require time to propagate their effects. We can see stars at night because of the light they emitted hundreds of years ago. We can smell the fragrant aroma of baking bread because heat gradually changed the structure of the food, emitting particles that traveled on the breeze. In this thesis, I investigate how people use temporal information to make causal inferences. I propose a rational framework for causal induction based on continuous-time evidence, examine human performance in passive and active continuous-time causal learning tasks, and develop bounded rational accounts that can offer explanations for human causal judgments and intervention strategies. Chapters 2 and 3 review previous theoretical frameworks on causal induction, and empirical work on the role of time in causal induction, respectively. Chapter 4 develops a rational framework for processing temporal evidence. It provides an explanation for how delays shape human causal induction and accounts for human causal judgments across seven different temporal causal learning tasks. Chapter 5 and Chapter 6 test how people passively or actively learn causal structures based on events unfolding in real time. I found people are capable temporal causal learners who successfully identify structures that involve generative and preventative relationships, as well as acyclic and cyclic connections. Nevertheless, the computational demands of normative learning could easily exceed human capacity. People’s causal judgments align better with an algorithm that approximates the normative solution via a simulation and local summary statistics scheme, suggesting the reliance on structurally local computation and temporally local evidence. People’s intervention decisions align better with a resource-rational model that emphasizes a balance between expected information and expected inferential complexity when choosing interventions. Chapter 7 shows that when given a limited period of observation, people not only focus on existing data, but also consider future possibilities, relying on extrapolated data to make inferences. This demonstrates the unique “continuing” feature of time, and how generalization plays a role in the utilization of temporal information. Chapter 8 synthesizes the findings of this thesis and proposes future research directions of causal learning in temporal contexts.

description: In this article, we introduce a novel backward method to model stochastic gene expression and protein level dynamics. The protein amount is regarded as a diffusion process and is described by a backward stochastic differential equation (BSDE). Unlike many other SDE techniques proposed in the literature, the BSDE method is backward in time; that is, instead of initial conditions it requires the specification of endpoint ("final") conditions, in addition to the model parametrization. To validate our approach we employ Gillespie's stochastic simulation algorithm (SSA) to generate (forward) benchmark data, according to predefined gene network models. Numerical simulations show that the BSDE method is able to correctly infer the protein level distributions that preceded a known final condition, obtained originally from the forward SSA. This makes the BSDE method a powerful systems biology tool for time reversed simulations, allowing, for example, the assessment of the biological conditions (e.g. protein concentrations) that preceded an experimentally measured event of interest (e.g. mitosis, apoptosis, etc.).

description: Clinical adoption of human genome sequencing requires methods with known accuracy of genotype calls at millions or billions of positions across a genome. Previous work showing discordance amongst sequencing methods and algorithms has made clear the need for a highly accurate set of genotypes across a whole genome that could be used as a benchmark. We present methods to make highly confident SNP, indel, and homozygous reference genotype calls for NA12878, the pilot genome for the Genome in a Bottle Consortium. We minimize bias towards any method by integrating and arbitrating between 14 datasets from 5 sequencing technologies, 7 mappers, and 3 variant callers. Regions for which no confident genotype call could be made are identified as uncertain, and classified into different reasons for uncertainty. Our highly confident genotype calls are publicly available on the Genome Comparison and Analytic Testing (GCAT) website to enable real-time benchmarking of any method.

description: The overarching objective of the FarFish project is to provide knowledge, tools and methods to support responsible, sustainable and profitable EU fisheries outside European waters, both within the jurisdiction of non-EU nations as well as international waters. In order to achieve this, the FarFish project has explored the applicability of implementing self-sampling programmes within EU long-distance fisheries and initiated a pilot self-sampling program as “proof of concept”.
 The pilot self-sampling programme was implemented on board three Sustainable Fisheries Partnership Agreement (SFPA) trawlers fishing for black hake (Merluccius poli and Merluccius senegalensis) in Mauritanian waters and Senegalese national vessels (Industrial and Artisanal). Sampling protocols and kits were provided by FarFish. The data collected includes fishing locations, dates, depth, visual identification of the species, sex and length. Fin clips were taken and stored in 100% ethanol. A total of 867samples were obtained from three SFPA trawlers belonging to OPROMAR, the fishing vessel Kanbal of the SOPERCA company in Senegal, and artisanal longline vessels from Senegal. DNA analysis was carried out at the University of Oviedo.
 Self-sampling was successfully carried out for all the fleets. However, results of the DNA analysis showed that mislabelling (misidentification) of black hake species is significant and variable, with differences between vessels of the same fleet (SFPA) and between the different sampled fleets (SFPA, Senegal Industrial and Senegal Artisanal). These differences may be explained in part by the geographic area and depth of the sampling location, with higher probabilities of misidentification in areas and depths where both species co-exist and are found together in the catches.
 These preliminary results, along with the results of a follow-up questionnaire to eight self-samplers from Senegal suggest that self-sampling on board SFPA vessels is viable, cost-effective and can provide valuable data for improving stock assessment and management. However, in the case of the black hakes, training of self-samplers in morphological identification is essential if reliable fisheries and biological data is to be collected by self-samplers.

description: We use numerical simulations to investigate the effect of different dissipative models on the shearing rheology of massive soft-core frictionless disks in two dimensions. We show that the presence of Newtonian (overdamped) vs Bagnoldian (inertial) rheology is related to the formation of large connected clusters of disks, and that sharp transitions may exist between the two as system parameters vary. In the limit of strongly inelastic collisions, we find that rheological curves collapse to a well-defined limit when plotted against an appropriate dimensionless strain rate.

description: We compute the properties of a sample of 221 local early-type galaxies with a spectral energy distribution (SED) modeling software, CIGALEMC. Concentrating on the star forming activity and dust contents, we derive parameters such as the specific star formation rate, the dust luminosity, dust mass and temperature. 52 % of our sample is composed of elliptical (E) galaxies and 48 % of lenticular (S0) galaxies. We find a larger proportion of S0 galaxies among galaxies with a large specific star formation rate (sSFR) and large specific dust emission. The stronger activity of S0 galaxies is confirmed by larger dust masses. We investigate the relative proportion of active galactic nuclei (AGN) and star-forming (SF) galaxies in our sample using spectroscopic SDSS data and near-infrared selection techniques, and find a larger proportion of AGN dominated galaxy in the S0 sample than the E one. This could corroborate a scenario where blue galaxies evolve into red ellipticals by passing through a S0 AGN active period while quenching its star formation. Finally, we find a good agreement comparing our estimates with color indicators.

Subjects: Taxation law

description: Base Erosion and Profit Sharing is a strategy of tax avoidance in which the taxpayer makes an arrangement to shift profits from high tax countries to lower ones. The non-uniformity of rules in different jurisdiction creates a gap which is utilised by the taxpayers to minimize the tax payment which the jurisdiction would be entitled to receive. After the arrival of the report, OECD members and G20 countries formulated a BEPS Action Plan. To give effect and implement the plan, the countries went ahead and on each item a report was prepared called BEPS Action Reports.The endeavour in the present paper is to analyse the plan in the light of requirement of adequate tax framework in the international tax system. To accomplish this, the researcher would initially understand the compelling reasons to bring BEPS into action. For this, the Pre-BEPS era is described then there is brief discussion on action plans. Further to this, the researcher attempts to analyse the short-coming and appraisals of the introduced plan. The researcher also describes the position of India in implementation of the BEPS Action Plan. The researcher has also presented certain arguments in relation to different impacts of BEPS on developing and developed nations. Also, in the contemporary time, the BEPS Action Plan implementation has suffered with many set-backs. Hence, the researcher has attempted to present certain recommendations to tackle the emerging issues.
IDENTIFICAZIONE DI NUOVI BIOMARKER E METODI ANALITICI INNOVATIVI IN PATOLOGIA CLINICA VETERINARIA

description: Diagnostic test validation is challenge for the clinical pathologist when a new instrument or a new analyzer is introduced in the lab. The aim of this work is to assess the analytical and/or clinical performances of novel biomarker to evaluate a possible application as a useful marker in veterinary medicine. Four different objectives are investigate: 1. Haematological parameters: two new gates are draw, in particular a ?high fluorescent region? to identify canine blood samples with cell of probable neoplastic origin that need further investigation and a gate to identify ?high fluorescent platelet fraction? in macrothrombocytopenic Norfolk terrier. Both gates are useful to perform a correct diagnosis with a better outcome for the patients. 2. Inflammatory markers: the measurement of dROMs (derivative of reactive oxygen metabolites) in serum of dogs with leishmaniasis showe a strong involvement of these compounds in the symptomatic or the asymptomatic Leishmania infections, and could be use to identify dogs with sub-clinical forms. Another studies involve the validation of a new test for IFN-? measurement after incubation of feline leukocytes with immunogenic peptides. This study is from one side a draw up of a new test with consequently assessment of analytical performances, and from another side a pathogenic study about FIP infection in cats. The paraoxonase 1 activity in dogs is the last inflammatory maker investigated, and results show a probable biological behaviour as a negative acute phase protein. 3. Hypertension markers: homocysteine and entothelin-1 (ET-1). Hypertension usually is secondary to diseases that indirectly could affect the systemic pressure, mainly renal and heart diseases. Homocysteine appears increased in dogs with both heart and kidney disease, but the clinical usefulness and the sensibility is not enough for positive impact on patient management. ET-1 appeared with higher sensibility and specificity in dogs with chronic kidney diseases and with hypertension, and its related with the severity of disease and could be a useful marker for the monitoring the follow up. 4. Development of new methods to investigate sialic acid characteristics and to assess if the different molecules bind to sialic acid molecules could interact with the development of the pathology. Results show an increased metastatic potential when sialic acid has ?2,6 conformation in dogs with mammary tumour, and in cats the total sialic acid serum concentration is related to the immune response of cats during Coronavirus infections. 5. At last, evaluation of analytical performances of urine protein-to-creatinine ratio: it?s a commonly used test, but this study revealed a high imprecision that could affect test results.

So zwingen weniger Geld und Personal bei gleichzeitig erheblichen neuen Aufgaben durch elektronische Medien die Bibliotheken zu einem Richtungswandel hinsichtlich ihrer Aufgaben, Funktionsweisen und Organisationsstruktur. Die Bibliotheksmitarbeiter sollen dabei hoch motiviert und leistungsbereit sein. Voraussetzung dafür ist aber, dass die Mitarbeiter ausreichend geschult sind, um mit den modernen Arbeitsmitteln richtig umgehen und die neuen Aufgaben umsetzten zu können. An dieser Stelle wird die Wichtigkeit von Personalentwicklung deutlich. Anhand eines konkreten Personalentwicklungskonzepts werden Möglichkeiten, aber auch Grenzen eines Personalentwicklungskonzepts in Bibliotheken erörtert.
