description: In the almost twenty years since the inception of No Child Left Behind in 2001, the United States has experienced school reform efforts at an unprecedented rate. Federal and State legislatures have attempted to leverage high stakes accountability systems in order to force change with little success. Likewise, grassroots efforts have been attempted by networks of school districts, but have lacked the resources to make systemic reforms. With the literature emphasizing the role of the district in education reform and transformation, the challenge appears to be how school districts can balance the demands of the high stakes accountability system still in place, while providing an environment supportive of the innovation necessary to transform the system. The purpose of this mixed methods study was to explore and understand the perspectives of educators, campus principals, and central office administrators regarding the coherence provided by a district created and implemented learning framework. The following research question guided the study: How do classroom educators, campus principals, and central office administrators of a school district focused on transformation experience coherence through a district created and implemented learning framework? The researcher utilized a mixed methodology study design with a sequential transformative strategy in order to explore and understand the lived experiences of the district’s elementary educators, elementary principals, and central office administrators. The quantitative data tool included a district-wide survey with yes/no, Likert scale, and open response questions. The qualitative methods included individual interviews, a focus group, and the review of district documents. A purposeful sampling strategy was utilized to select 2 central office administrators, and 1 elementary campus principal from each of the 3 middle school feeder patterns. A snowball strategy was utilized to select the classroom educators to participate in the study. The analysis of the quantitative and qualitative data resulted in a narrative supporting the creation of themes relating to how the classroom educators, campus principals, and central office administrators experience and understand the level and impact coherence provided by the district created learning framework. Implications for practice evolving from this study extend to researchers, campus principals, central office administrators, and superintendents.

description: Archival EAS-MSU data are searched for anomalous muonless events which may be caused by primary gamma rays with energies between 10^15 eV and 10^18 eV. We consider a refined sample of high-quality data and confirm the previously reported detection of a non-zero gamma-ray flux at ~5x10^16 eV with a similar flux value but at somewhat lower statistical significance, corresponding to the depletion of the sample. We present upper limits on the flux below and above these energies, including the first constraints in the range (10^17-10^18) eV never studied by any other experiment.

description: We study a method of reducing space dimension in multi-dimensional Black-Scholes partial differential equations as well as in multi-dimensional parabolic equations. We prove that a multiplicative transformation of space variables in the Black-Scholes partial differential equation reserves the form of Black-Scholes partial differential equation and reduces the space dimension. We show that this transformation can reduce the number of sources of risks by two or more in some cases by giving remarks and several examples of financial pricing problems. We also present that the invariance of the form of Black-Scholes equations is based on the invariance of the form of parabolic equation under a change of variables with the linear combination of variables.

Temnothorax terrigena

description: terrigena group overview This group is monotypic, with the nominal Temnothorax terrigena being the only member. The range of T. terrigena small, restricted to the low elevations of the southern United States and northern Mexico (Fig. 170G). Apparently, this species is ground nesting, and the generalized habitus has led to confusion about its relationships historically, but the moderately arched mesosoma dorsum and broad postpetiole are telltale signs of its membership in the salvini clade. Temnothorax terrigena may be confused with members of the andrei and sallei clades, and other members of the salvini clade. See the ‘similar species’ section below to distinguish this species.

Founding Fathers : constitutive rhetoric and discourses of masculinity

description: “Founding Fathers: Constitutive Rhetoric and White Masculinity,” uses archival and digital research methods to assess how contemporary political speakers engage America’s past via reference to the Founding Fathers. Through case studies of different political communities—Democrats, Republicans, and Libertarians—I draw two conclusions. First, most references to the Founding Fathers do not refer to specific persons; that is, references operate as signifier without a signified. Second, while references to the Founding Fathers are unspecific about the persons they summon, they are highly specific in the kinds of bodies they summon. That is, reference to Founding Fathers tends to elicit identification between white men on the basis of their shared race and gender. From these conclusions, I argue that reference to the Founding Fathers tends to establish political authority based on racial and gendered likeness between a rhetor and the mythologized figures of America’s past, such that whiteness and masculinity serve as architypes for American identity.

description: Schrodinger-type wave equations with logarithmic nonlinearity occur in hydrodynamic models of Korteweg-type materials with capillarity and surface tension, which can undergo liquid-solid or liquid-gas phase transitions. One of the predictions of the theory is a periodic pattern of density inhomogeneities occurring in the form of either bubbles (topological phase), or cells (non-topological phase). Such inhomogeneities are described by solitonic solutions of a logarithmic wave equation, gaussons and kinks, in the vicinity of the liquid-solid phase transition. During the solidification process, these inhomogeneities become centers of nucleation, thus shaping the polycrystalline structure of the metal grains. The theory predicts a Gaussian profile of material density inside such a cell, which should manifest in a Gaussian-like profile of microhardness inside a grain. We report experimental evidence of large-scale periodicity in the structure of grains in the ferrite steel S235/A570, copper C-Cu/C14200, austenite in steel X10CrNiTi18-10/AISI 321, and aluminium-magnesium alloy 5083/5056; and also Gaussian-like profiles of microhardness inside an averaged grain in these materials.

description: The primary purpose is to introduce and explore projective varieties, $\text{GRASS}_{\bf d}(Λ)$, parametrizing the full collection of those modules over a finite dimensional algebra $Λ$ which have dimension vector $\bf d$. These varieties extend the smaller varieties previously studied by the author; namely, the projective varieties encoding those modules with dimension vector $\bf d$ which, in addition, have a preassigned top or radical layering. Each of the $\text{GRASS}_{\bf d}(Λ)$ is again partitioned by the action of a linear algebraic group, and covered by certain representation-theoretically defined affine subvarieties which are stable under the unipotent radical of the acting group. A special case of the pertinent theorem served as a cornerstone in the work on generic representations by Babson, Thomas, and the author. Moreover, applications are given to the study of degenerations.

description: Many planners throughout history have attempted to achieve a holistic society through physical and policy planning. Garden Cities of To-morrow by Ebenezer Howard is a mainstay in planning curriculum, and yet activities today are still considered fringe in the professional field. Howard’s vision of well-connected network of mostly self sustaining towns, provided with local food, jobs, commerce, and recreational space is generally viewed as positive, pleasant, even admirable- but ultimately impractical. Today, no theme is more central to the minds of planners than sustainability. A concept that encapsulates environmental, social, and economic concerns, sustainability is a great challenge. Planners try to find balance between, and often act as intermediaries between competing networks of stakeholders, vying for more power over the two other spheres. However, communities that have self-organized have reached a level of success and sustainability beyond chance. These communities could serve as a model for the wider planning community going forward. This research hopes to address questions surrounding the ways in which communities can increase sustainability through providing services, and if or how these insights may inform planning on a wider scale. This report investigates how these visions and ideals are being attempted in the United States today. There is a range of scales and a variety of approaches to create places that are holistic. Three sites serve as examples of the breadth of communities, ranging from Twin Oaks Ecovillage and Intentional Community, the Greater World Community created by Earthship Biotecture, and the town of Arcosanti. These sites were examined using a two-part matrix including food, water, employment, education, energy, healthcare, entertainment, transportation, and housing in part one and ownership schemes and affordability in part two. Climate and controversies were also considered. This matrix was partially inspired by The Austin Area Sustainability Indicators project. Research revealed that there were common themes among the communities despite their differences, among them being a spirit of revolution, progressive ideals, and novel technology. Further, it was found that the most sustainable or complete community was not necessarily the most applicable to the wider planning field.

description: At leading twist the transverse-momentum dependent parton distributions of the pion consist of two functions, the unpolarized $f_{1,π}(x,\boldsymbol k^{\, 2}_\perp)$ and the Boer-Mulders function $h_{1,π}^{\perp}(x,\boldsymbol k^{\, 2}_\perp)$. We study both functions within a light-front constituent model of the pion, comparing the results with different pion models and the corresponding nucleon distributions from a light-front constituent model. After evolution from the model scale to the relevant experimental scales, the results for the collinear pion valence parton distribution function $f_{1,π}(x)$ are in very good agreement with available parameterizations. Using the light-front constituent model results for the Boer-Mulders functions of the pion and nucleon, we calculate the coefficient $ν$ in the angular distribution of Drell-Yan dileptons produced in pion-nucleus scattering, which is responsible for the violation of the Lam-Tung relation. We find a good agreement with data, and carefully discuss the range of applicability of our approach.

description: Sustainable building is one area where innovation is constantly being challenged. Innovation means offering something new or changing what exists in order to achieve new results. At present the hardest goal is transforming the current situation where the construction sector has the highest fossil fuel consumption, is the largest producer of non-reusable waste and the biggest polluter. In fact, the environmental impact of building design and construction is enormous: in Europe buildings are responsible, directly or indirectly, for approximately 40% of total primary energy consumption and for around 36% of CO2 total emissions. Sustainability criteria can minimize or eliminate negative environmental impacts through a conscious choice of design and constructive practices better than those commonly in use. This design approach allows a reduction in operating costs, an increase in market value and users' productivity. ... [edited by Author]

description: Quantum gates and entanglement based on dipole-dipole interactions of neutral Rydberg atoms are relevant to both fundamental physics and quantum information science. The precision and robustness of the Rydberg-mediated entanglement protocols are the key factors limiting their applicability in experiments and near-future industry. There are various methods for generating entangling gates by exploring the Rydberg interactions of neutral atoms, each equipped with its own strengths and weaknesses. The basics and tricks in these protocols are reviewed, with specific attention paid to the achievable fidelity and the robustness to the technical issues and detrimental innate factors.

description: We present optical lightcurves of variable stars consistent with the positions of X-ray sources identified with the Chandra X-ray Observatory for the Chandra Galactic Bulge Survey. Using data from the Mosaic-II instrument on the Blanco 4m Telescope at CTIO, we gathered time-resolved photometric data on timescales from $\sim2$ hr to 8 days over the $\frac{3}{4}$ of the X-ray survey containing sources from the initial GBS catalog. Among the lightcurve morphologies we identify are flickering in interacting binaries, eclipsing sources, dwarf nova outbursts, ellipsoidal variations, long period variables, spotted stars, and flare stars. $87\%$ of X-ray sources have at least one potential optical counterpart. $24\%$ of these candidate counterparts are detectably variable; a much greater fraction than expected for randomly selected field stars, which suggests that most of these variables are real counterparts. We discuss individual sources of interest, provide variability information on candidate counterparts, and discuss the characteristics of the variable population.

description: We ask whether the Eigenstate Thermalization Hypothesis (ETH) is valid in a strong sense: in the limit of an infinite system, {\it every} eigenstate is thermal. We examine expectation values of few-body operators in highly-excited many-body eigenstates and search for `outliers', the eigenstates that deviate the most from ETH. We use exact diagonalization of two one-dimensional nonintegrable models: a quantum Ising chain with transverse and longitudinal fields, and hard-core bosons at half-filling with nearest- and next-nearest-neighbor hopping and interaction. We show that even the most extreme outliers appear to obey ETH as the system size increases, and thus provide numerical evidences that support ETH in this strong sense. Finally, periodically driving the Ising Hamiltonian, we show that the eigenstates of the corresponding Floquet operator obey ETH even more closely. We attribute this better thermalization to removing the constraint of conservation of the total energy.

Ambiguity-Driven Fuzzy C-Means Clustering: How to Detect Uncertain Clustered Records

description: As a well-known clustering algorithm, Fuzzy C-Means (FCM) allows each input sample to belong to more than one cluster, providing more flexibility than non-fuzzy clustering methods. However, the accuracy of FCM is subject to false detections caused by noisy records, weak feature selection and low certainty of the algorithm in some cases. The false detections are very important in some decision-making application domains like network security and medical diagnosis, where weak decisions based on such false detections may lead to catastrophic outcomes. They are mainly emerged from making decisions about a subset of records that do not provide enough evidence to make a good decision. In this paper, we propose a method for detecting such ambiguous records in FCM by introducing a certainty factor to decrease invalid detections. This approach enables us to send the detected ambiguous records to another discrimination method for a deeper investigation, thus increasing the accuracy by lowering the error rate. Most of the records are still processed quickly and with low error rate which prevents performance loss compared to similar hybrid methods. Experimental results of applying the proposed method on several datasets from different domains show a significant decrease in error rate as well as improved sensitivity of the algorithm.

description: Group II intron reverse transcriptases from bacterial thermophiles have high fidelity, processivity and thermostability. With these properties, thermostable group II intron reverse transcriptases are thought to be more advantageous in different biotechnological applications, such as RNA sequencing and qRT-PCR, than widely- adopted retroviral reverse transcriptases. In this dissertation, I begin with evaluating the usage of thermostable group II intron reverse transcriptase end-to-end template-switching activities in rapid preparations of strand-specific, low bias RNA sequencing libraries for the Illumina short-read sequencing platform. By comparing RNA sequencing results from thermostable group II intron reverse transcriptases to that of other widely-adopted commercially-available RNA-seq kits, I demonstrated that this method provided a more accurate and comprehensive measurement of RNA expressions in biological samples. Using RNA sequencing data generated with this novel class of reverse transcriptase, I also showed that current state-of-the-art bioinformatic tools were not optimal for analyzing all RNA classes and biasing against small RNA and RNA with high abundant of mutations and modifications. Finally, I also established an efficient method to prepare high-quality single-stranded DNA sequencing libraries by exploiting the end-to-end template-switching activity and the DNA-dependent, DNA-polymerase activity of this reverse transcriptase and demonstrated its use in liquid biopsies.

description: Recent experimental conductance measurements performed on paramagnetic molecular adsorbates on a superconducting surface, using superconducting scanning tunneling microscopy techniques, are theoretically investigated. For low temperatures, we demonstrate that tunneling current assisted excitations of the local magnetic moment cannot occur for voltage biases smaller than the superconducting gap of the scanning tunneling microscope. The magnetic moment is only excited for voltages corresponding to the sum of the superconducting gap and the spin excitation energies. In excellent agreement with experiment, we show that pumping into higher excitations give additional current signatures by accumulation of density in the lower ones. Using external magnetic fields, we Zeeman split possible degeneracy and thereby resolve all excitations comprised in the magnetic moment.

description: This qualitative, multi-case study examines the classroom interactions between three critical elementary teachers and their students during interactive read-aloud events with multicultural children’s literature. For one school year, I observed and video- and audio- recorded these teachers’ read-alouds and literature discussions in order to consider the following three research questions: 1. How do elementary literacy teachers sustain and grow their enactment of critical pedagogies? 2. During whole-group discussions of multicultural children’s literature, how do teachers address critical sociocultural knowledge and issues of inequity? 3. How do teachers who practice critical pedagogy navigate the critical encounters that arise when they discuss multicultural children’s literature? Drawing on Freire’s (1970/2000) theory of critical literacy, Kumashiro’s (2001; 2009) theory of anti-oppressive education, and Brown’s (2013) theory of humanizing critical sociocultural knowledge, my analysis centered on illuminating the ways that Ms. Smith, Ms. Barker, and Ms. Martinez enacted critical pedagogies within this structure of literacy instruction, as well as gaining insight into how these teachers sustained and grew their work as critical educators. I took an ethnographic approach to data collection; and I used qualitative and discourse analytic methods to analyze within and across multiple data sources, including audio- and video-recordings, transcriptions, classroom artifacts (e.g., students’ reader responses, photos of language charts), memos, and field notes. In response to my first research question, I report that these teachers sustained and grew their enactment of critical pedagogies by designing an all-encompassing curriculum of experiences for themselves (Brown, 2013) in both their professional and personal lives, engaging in [social justice] praxis, and pursuing opportunities to learn new critical sociocultural knowledge. In response to my second and third research questions, I report that teachers address critical sociocultural knowledge and navigate critical encounters with their students by: a) reimagining the possibilities of interactive read aloud in the elementary classroom; b) extending talk towards criticality; c) turning discourse back to the students. These three cases demonstrate that teachers can offer rich literacy instruction, as well as intentional, daily space to collaboratively build humanizing critical sociocultural knowledge towards transformation.

description: Various methods using machine and deep learning have been proposed to tackle different tasks in predictive process monitoring, forecasting for an ongoing case e.g. the most likely next event or suffix, its remaining time, or an outcome-related variable. Recurrent neural networks (RNNs), and more specifically long short-term memory nets (LSTMs), stand out in terms of popularity. In this work, we investigate the capabilities of such an LSTM to actually learn the underlying process model structure of an event log. We introduce an evaluation framework that combines variant-based resampling and custom metrics for fitness, precision and generalization. We evaluate 4 hypotheses concerning the learning capabilities of LSTMs, the effect of overfitting countermeasures, the level of incompleteness in the training set and the level of parallelism in the underlying process model. We confirm that LSTMs can struggle to learn process model structure, even with simplistic process data and in a very lenient setup. Taking the correct anti-overfitting measures can alleviate the problem. However, these measures did not present themselves to be optimal when selecting hyperparameters purely on predicting accuracy. We also found that decreasing the amount of information seen by the LSTM during training, causes a sharp drop in generalization and precision scores. In our experiments, we could not identify a relationship between the extent of parallelism in the model and the generalization capability, but they do indicate that the process' complexity might have impact.

description: Η υποκινητικότητα αποτελεί ένα σημαντικό πρόβλημα κυρίως στις γυναίκες, οι οποίες παρουσιάζουν ελλιπή φυσική δραστηριότητα σε ποσοστό μεγαλύτερο των ανδρών. Σκοπός της έρευνας ήταν η διερεύνηση της επίδρασης ενός παρεμβατικού συμβουλευτικού προγράμματος έντυπης μορφής, στην αύξηση της φυσικής δραστηριότητας σε ενήλικες γυναίκες, καθώς και η αποτελεσματικότητα της επιπρόσθετης προφορικής καθοδήγησης και παρότρυνσης. Στην έρευνα συμμετείχαν 40 γυναίκες ηλικίας από 25 έως 65 ετών οι οποίες χωρίστηκαν σε δύο ομάδες. Την μία, ομάδα (Α), αποτέλεσαν 24 γυναίκες ηλικίας (ΜΟ=37,6 + 7.7 έτη) και την άλλη, ομάδα (Β) 16 γυναίκες ηλικίας (ΜΟ=45,2 + 10.3 έτη). Οι συμμετέχουσες που ανήκαν στην Α ομάδα δέχονταν κάθε εβδομάδα τις ίδιες γραπτές οδηγίες με την Β ομάδα αλλά επιπρόσθετα δέχονταν προφορικές συμβουλές καθοδήγησης και παρότρυνσης προσαρμοσμένες στις ατομικές ανάγκες της κάθε συμμετέχουσας για αύξηση της φυσικής δραστηριότητας. Οι συμμετέχουσες που ανήκαν στην Β ομάδα δέχονταν κάθε εβδομάδα το ίδιο έντυπο υλικό χωρίς όμως την καθοδήγηση και την παρότρυνση. Το συμβουλευτικό πρόγραμμα αύξησης της φυσικής δραστηριότητας είχε διάρκεια 12 εβδομάδες και το επίπεδο φυσικής δραστηριότητας μετρήθηκε πριν και μετά με τη χρήση του ερωτηματολογίου IPAQ (Craig et al., 2003). Σύμφωνα με την ανάλυση διακύμανσης με επαναλαμβανόμενες μετρήσεις τα αποτελέσματα έδειξαν ότι και οι δύο ομάδες αύξησαν συνολικά τη φυσική δραστηριότητα, χωρίς ωστόσο να υπάρχουν στατιστικά σημαντικές διαφορές μεταξύ των ομάδων (ρ>.05). Διαφορές μεταξύ των δύο ομάδων εντοπίστηκαν προς όφελος της Α ομάδας στο περπάτημα (ρ< .05), και προς όφελος της Β ομάδας στη φυσική δραστηριότητα κατά τον ελεύθερο χρόνο (ρ< .05). Συμπερασματικά και οι δύο ομάδες που ακολούθησαν το παρεμβατικό συμβουλευτικό πρόγραμμα έντυπης μορφής αύξησαν τη φυσική δραστηριότητα τους, ενώ οι επιπρόσθετες προφορικές συμβουλές και παρότρυνση επηρέασαν μόνο τη μορφή της φυσικής δραστηριότητας, με την A ομάδα να αυξάνει σημαντικά το περπάτημα και τη Β τη φυσική δραστηριότητα στον ελεύθερο χρόνο.

description: Increasingly, firms need to develop strategies to cope with unanticipated events and challenges in a rapidly changing external environment. Whether a firm can keep up with a high-velocity, complex market is determined by whether it adopts appropriate marketing strategies. In my dissertation, I examine how firms can effectively use marketing to achieve strong financial performance in the presence of sweeping institutional changes. In the first essay in my dissertation, I examine incumbent firms’ marketing mix responses to turbulence in their environment in the form of liberalization. Many governments are opening up their economies to foreign competition, with the expectation that it will increase economic growth. While foreign competitors with superior technology and management practices pose serious threats to incumbent firms, they also provide them an opportunity to gain new knowledge. In this essay, I explore the following two questions. First, how do incumbent firms, who have thus far operated in a highly protected market, respond to liberalization? Second, how do incumbent firms’ responses affect their performance? The findings suggest that incumbent firms’ knowledge significantly shapes their marketing mix responses to liberalization and that their performance outcomes are significantly affected by their marketing mix responses. In the second essay in my dissertation, I examine the effect of environmental turbulence in the form of CSR mandates on firms’ performance. While firms’ CSR initiatives have been traditionally considered voluntary, in an attempt to achieve inclusive development, some governments are enacting policy to encourage firms to engage in CSR initiatives. Can firms make strategic use of CSR mandates? CSR mandates affect two types of firms – those that were already engaging in CSR spending before the mandate (already-compliers), and those that are doing so for the first time (first-time compliers). The findings suggest that both already-compliers and first-time compliers can increase their shareholder value through their mandated CSR spending by increasing their advertising and research and development (R&D) spending. In addition, while already-compliers can increase their shareholder value through their mandated CSR spending by introducing mechanisms to alleviate agency concerns, first-time compliers can do so by decreasing their promotion spending

description: Discriminatory trade liberalization policies are becoming more popular among world economies. Countries are motivated to enter for regional trade agreements to capture faster economic growth for alleviating poverty. In developing economies like most of the member countries of the Association of South East Asian Nations (ASEAN), a sizeable portion of people are suffering from poverty by exposing them to food insecurity. Low level of income and low productivity of agricultural sector have augmented the severity of food insecurity of those people. Discriminatory trade liberalization policies are expected to reduce poverty and strengthen the food security. The objective of this paper is to examine the effect of ASEAN Free Trade Agreement (AFTA) on food security of its member countries. The multiple regression analysis in panel data was employed to disentangle the impacts of trade liberalization on food securit y with use of regional trade agreement dummy variable. The finding of the study supports that AFTA has influenced positively on food security of its member nations. After the formation of AFTA, the level of per-capita daily dietary energy supply of the member countries has been increased moderately over time.
title: Charakterisierung von benetzbaren Systemen mittels Beschreibung des Kapillarverhaltens unter Rotationsbedingungen

description: Der Einsatz poröser Materialien wie bspw. für Verpackungen sind sowohl die mechanischen Eigenschaften als auch insbesondere die Interaktion mit Fluiden, besonders Wasser, von größter Bedeutung. Die Optimierung der mechanischen Papiereigenschaften für den vorgesehenen Einsatz erfolgt meist durch eine Vorbehandlung der Fasern vor der Herstellung. So wird z.B. durch die Erhöhung der Fibrillierung des ausgewählten Zellstoffs durch Mahlen die Zugfestigkeit des Papiers deutlich erhöht. Wird das Fasernetzwerk jedoch in einer wässrigen Umgebung eingesetzt, wie z. B. in mikrofluidischen Experimenten, wirkt sich die erhöhte Aufrauhung der Fasern auch erheblich auf das Flüssigkeitsverhalten aus, was sowohl auf die Porenstruktur als auch auf Reibungseffekten zurückgeführt werden kann. Trotz zahlreicher mathematischer Modelle, die in den letzten Jahren entwickelt wurden, ist die Zahl der verschiedenen intrinsischen und extrinsischen Parameter, die die Flüssigkeitsströmung in Papier beeinflussen können, zu groß, um eine angemessene Beschreibung zu liefern. Insbesondere die Reibungskräfte, die als Gegenkraft zur kapillargetriebenen Flüssigkeitsströmung wirken, sind in diesen komplexen Systemen schwer zu quantifizieren. Im Rahmen dieser Arbeit wurden die Reibungskraft durch die wohldefinierte Zentrifugalkraft als Gegenkraft ersetzt, welches ermöglichte, sowohl den mittleren Porenradius des Fasernetzes als auch einen quantitativen Wert, welcher mit dem Druckabfall korreliert, zu bestimmen. Auf diese Weise können die Einflüsse der Fasermorphologie, wie z.B. die Wahl des Zellstoffs, des Mahlgrads, des Fraktionierungsgrads, sowie die Auswirkungen der Fluidströmung durch verschiedene komprimierte Papiere und die Einflüsse der hydrophilen Kanalbreite bestimmt werden. Neben der Anwendung an verschiedenen Substraten wird ebenso die Konstruktion solche eines Rotationsgerätes beschrieben.
Interculturalism in Italy: Is it merely a Language and Communication Problem?

description: It is unthinkable today not to promote or encourage intercultural communication, it being the only alternative to conflict: a dialogic interaction designed to promote all the instances in the game and to achieve equilibrium points that are recognized by the parties involved. It is necessary to activate transformation processes in the subjects' cognitive system, so that they experience occurrences as a synthesis and reinterpretation of several cultures. Indeed, the presence of different cultures leads to the construction of new cultural identities, either multi- or trans-ethnic ones, and multiculturalism is a multidimensional process of interaction between people with different cultural identities, who, through the meeting of cultures, live a deep and complex conflict/reception experience, as a valuable opportunity for their personal growth, from the standpoint of changing everything that creates an obstacle to the construction of a new civil society.

description: Στα πλαίσια της παρούσας εργασίας επιχειρείται η παρουσίαση της μεθοδολογίας της Balanced Scorecard (Εξισορροπημένης Κάρτας Αποτελεσμάτων), ως ένα σύγχρονο και ευέλικτο εργαλείο Διαχείρισης της Απόδοσης στο Δημόσιο τομέα. Αρχικά, γίνεται μια εκτενής αναφορά στους λόγους που επέβαλλαν τη μετάβαση από την απλή μέτρηση της απόδοσης στη 'Διαχείριση της απόδοσης'. Περιγράφονται τα χαρακτηριστικά των αποδοτικών συστημάτων Διαχείρισης της απόδοσης, και αναπτύσσεται η φιλοσοφία αυτών των συστημάτων που τα καθιστά εξίσου αποτελεσματικά τόσο στον ιδιωτικό όσο και στο δημόσιο τομέα. Κατόπιν, παρουσιάζεται η θεωρία της Balanced Scorecard, η οποία περιλαμβάνει πολλά στοιχεία άλλων θεωριών σχετικά με τη μέτρηση της απόδοσης, αλλά αποτελεί μια ολοκληρωμένη διαδικασία, που περιλαμβάνει στοχοθέτηση, αξιολόγηση και λήψη αποφάσεων για τη βελτίωση των επιδόσεων σε όλα τα επιμέρους τμήματα των επιχειρήσεων ή οργανισμών, κατά τρόπο που να υπάρχει ευθυγράμμιση και εστίαση στη στρατηγική. Στη φάση αυτή γίνεται διεξοδική αναφορά στη φιλοσοφία της εν λόγω θεωρίας, με έμφαση στις τέσσερις βασικές συσχετισμένες προοπτικές που τη συνθέτουν, περιγράφονται οι στόχοι και η μεθοδολογία της και αιτιολογείται η αναγκαιότητα εφαρμογής της ως ένα σύγχρονο εργαλείο διοίκησης των επιδόσεων. Επίσης, περιγράφεται η αρχιτεκτονική μιας Balanced Scorecard και ο τρόπος δημιουργίας και υλοποίησής της. Στη συνέχεια, γίνεται μια αναφορά στη Δημόσια Διοίκηση και στα χαρακτηριστικά της διοίκησης με βάση την απόδοση στο Δημόσιο τομέα. Στο κεφάλαιο αυτό δίνεται ιδιαίτερη έμφαση στους παράγοντες διαφοροποίησης της στρατηγικής του δημόσιου τομέα σε σχέση με τον ιδιωτικό, και στη συμβολή του ανθρώπινου κεφαλαίου στη αλυσίδα αξίας ενός δημόσιου οργανισμού. Παρουσιάζονται επίσης, οι τέσσερις βασικοί άξονες (προοπτικές) της Balanced Scorecard, όπως διαμορφώνονται για την εφαρμογή της στο δημόσιο τομέα. Ακολουθεί μια πρόταση εφαρμογής της Balanced Scorecard στις Δημόσιες Οικονομικές Υπηρεσίες (Δ.Ο.Υ) του Υπουργείου Οικονομικών, όπου παρουσιάζεται ο σχεδιασμός της Balanced Scorecard στην πράξη, ενώ επισημαίνονται οι παράμετροι που θα πρέπει να ληφθούν υπόψη στην υλοποίησή της, καθώς η τελευταία δεν ήταν εφικτό να πραγματοποιηθεί στα πλαίσια της παρούσας εργασίας. Τέλος, η εργασία καταλήγει στην αποτίμηση του Συστήματος Διαχείρισης της Απόδοσης 'Balanced Scorecard' αναφέροντας τη χρησιμότητα, τα πλεονεκτήματά της και τις αδυναμίες της και ολοκληρώνεται με την παράθεση των κύριων συμπερασμάτων που προέκυψαν
Monad Transformers for Backtracking Search

description: This paper extends Escardo and Oliva's selection monad to the selection monad transformer, a general monadic framework for expressing backtracking search algorithms in Haskell. The use of the closely related continuation monad transformer for similar purposes is also discussed, including an implementation of a DPLL-like SAT solver with no explicit recursion. Continuing a line of work exploring connections between selection functions and game theory, we use the selection monad transformer with the nondeterminism monad to obtain an intuitive notion of backward induction for a certain class of nondeterministic games.

description: This dissertation explores the narratives of Tommaso Buscetta (Italy’s first pentito from Cosa nostra) as an exemplum of historically dominant discourses on organized crime. Departing from Buscetta’s 1984 Depositions, this dissertation aims to fill a void in existing scholarship on the representation of organized crime across media. The author argues that Tommaso Buscetta, both in his own self-modelling and in the subsequent narratives that arose from his collaboration with the Italian State, can be read as a continuity with literarily produced narratives of a noble mafia and in which the mafioso represents honor, dignity, and respect. Based on archival research on Buscetta’s depositions, print news media during the 1986 Maxi Trial of Palermo, and on literary and media research into the offspring narratives (biographies and docudramas, mainly), this dissertation provides an analysis of the tenacity of apologist mafia narratives and their implications in the historical world. Through theoretical engagement with recent studies on autobiography, co-authorship, celebrated criminality, and docudrama, the author of this dissertation provides the first study of Tommaso Buscetta as a transmedia icon.

description: Recently, the domination vertex degree concept was defined in Chemical Graph Theory. In this paper, we introduce the first and second hyper Gourava domination indices and their corresponding polynomials of a graph. Furthermore, we compute these newly defined hyper Gourava domination indices and their corresponding polynomials for some standard graphs, book graphs, French windmill graphs and friendship graphs.

description: Interfaces advancing through random media represent a number of different problems in physics, biology and other disciplines. Here, we study the pinning/depinning transition of the prototypical non-equilibrium interfacial model, i.e. the Kardar-Parisi-Zhang equation, advancing in a disordered medium. We analyze separately the cases of positive and negative non-linearity coefficients, which are believed to exhibit qualitatively different behavior: the positive case shows a continuous transition that can be related to directed-percolation-depinning while in the negative case there is a discontinuous transition and faceted interfaces appear. Some studies have argued from different perspectives that both cases share the same universal behavior. Here, by using a number of computational and scaling techniques we shed light on this puzzling situation and conclude that the two cases are intrinsically different.
