description: The electronic properties of $π$-conjugated two-dimensional (2D) polymers near the Fermi level are determined by structural topology and chemical composition. Thus, tight-binding (TB) calculations of the corresponding fundamental network can be used to explore the parameter space to find configurations with intriguing properties before designing the the atomistic 2D polymer network. The vertex-transitive \textbf{fes} lattice, which is also called square-octagon lattice, is rich in interesting topological features including Dirac points and flat bands. Herein, we study its electronic and topological properties within the TB framework using representative parameters for chemical systems. Secondly, we demonstrate that the rational implementation of band structure features obtained from TB calculations into 2D polymers is feasible with a family of 2D polymers possessing \textbf{fes} structure. A one-to-one band structure correspondence between fundamental network and 2D polymers is found. Moreover, changing the relative length of linkers connecting the triangulene units in the 2D polymers reflect tuning of hopping parameters in the TB model. These perturbations allow to open sizeable local band gaps at various positions in the Brillouin zone. From analysis of Berry curvature flux, none of the polymers exhibits a large topologically non-trivial band gap. However, we find a particular configuration of semimetallic characteristics with separate electron and hole pockets, which possess very low effective masses both for electrons (as small as $m^*_\mathrm{e} = 0.05$) and holes (as small as $m^*_\mathrm{h} = 0.01$).

description: We consider a disordered spin model with multi-spin interactions undergoing a glass transition. We introduce a dynamic and a static length scales and compute them in the Kac limit (long--but--finite range interactions). They diverge at the dynamic and static phase transition with exponents (respectively) -1/4 and -1. The two length scales are approximately equal well above the mode coupling transition. Their discrepancy increases rapidly as this transition is approached. We argue that this signals a crossover from mode coupling to activated dynamics.

description: The diet and breeding patterns of Mastomys natalensis in semi-arid areas of Isimani division, Iringa region, Tanzania were investigated in maize fields and fallow land. The aim was to investigate the influence of diet on breeding patterns of M. natalensis. Removal trapping was used to capture rodents and analyse diet categories while Capture-mark-release trapping was used to investigate breeding patterns of female M. natalensis. Mastomys natalensis comprised 94% of the total capture, and the remaining 6% comprised of six other species. Statistical analysis of food preferences indicated that both vegetative materials and seeds were significantly higher in the overall diet of M. natalensis compared with other food materials. Significant differences in the proportions of vegetative materials and seeds were found between seasons (dry, wet), but not between habitats (fallow, maize). There was a clear seasonal pattern in the proportion of reproductively active females with peaks in April and troughs in October. The proportion of vegetative materials was highest during the wet season and correlated positively with reproductive activity, suggesting that vegetative materials contain certain compounds (e.g. 6-MBOA) that trigger reproductive activity in M. natalensis. The breeding activity of M. natalensis in semi-arid areas might, thus, be reduced by limiting access to fresh vegetative food (e.g. young sprouting grass).

description: We study the intermittent fluorescence of a single molecule, jumping from the "light on" to the "light off" state, as a Poisson process modulated by a fluctuating environment. We show that the quasi-periodic and quasi-deterministic environmental fluctuations make the distribution of the times of sojourn in the "light off" state depart from the exponential form, and that their succession in time mirrors environmental dynamics. As an illustration, we discuss some recent experimental results, where the environmental fluctuations depend on enzymatic activity.

Ο σκοπός της παρούσας εργασίας είναι να συνεισφέρει στη θεωρητική τεκμηρίωση της μεταβλητής εντοπίζοντας ένα μηχανισμό που να περιγράφει πως οι αρνητικές διαπροσωπικές σχέσεις μεταξύ των εργαζομένων επηρεάζουν την εμπειρία της ακμής. Σε έρευνα που πραγματοποιήθηκε σε υπαλλήλους εννέα διαφορετικών τραπεζικών ιδρυμάτων βρέθηκε πρώτον, ότι η απρεπής συμπεριφορά που προέρχεται από τους συναδέλφους επηρεάζει την ικανότητα του εργαζόμενου να ακμάσει και δεύτερον, ότι η ανάγκη του ανθρώπου για κοινωνική αποδοχή (need to belong, belonging) λειτουργεί ως διαμεσολαβητής (mediator) στη σχέση αυτή.

The Relationship Between Self-Monitoring and Successful Ingratiation
Creators: name: Johnson, Mark B.
Publisher: name: Digital Repository at the University of Maryland
Year: 2002

description: According to self-monitoring theory, high self-monitors should be more skilled at
self-presentation than low self-monitors. Research has shown that high self-monitors do
possess skills ostensibly related to self-presentation, but there is no empirical evidence
that they are any better at achieving self-presentation goals. Conversely, the selfpresentation
literature has identified self-presentation strategies that do facilitate
achieving interpersonal goals. One component of self-presentation skill, therefore, may
involve knowing what strategy to use in achieving self-presentation success. This
research examines the self-presentation strategies used by high and low self-monitors in
their attempt to achieve the goal of being liked.
Previous research has found that presenting one's positive interpersonal qualities
tend to increase liking, whereas presenting one's abilities and achievements tend to
reduce liking. It was hypothesized that when faced with the goal of being liked, high selfmonitors,
more so than low self-monitors, would choose to emphasize their positive
interpersonal qualities and to be modest in presenting their achievements. It was
hypothesized further that the selection of self-presentation strategies would have actual
interpersonal consequences. It was predicted that the presentation of positive
interpersonal qualities would increase liking, whereas the promotion of abilities and
achievements would decrease liking.
Three studies were conducted to test these hypotheses. In two studies, high and
low self-monitoring participants fabricated personality descriptions they believed another
person would like very much. Contrary to prediction, high self-monitors promoted
abilities and achievements more extensively than low self-monitors. In a third study
designed to examine self-monitors' expectations regarding different self-presentation
strategies, high self-monitors believed that promoting abilities would lead to greater
liking than did low self-monitors. Results indicated that presentations that extolled
interpersonal qualities did produce greater liking than did presentations that extolled
achievements and abilities. Thus, high self-monitors did not use the self-presentational
strategy that was more likely to succeed. The implications of the findings are discussed.
Mixed regression models for discrete data

Publisher: name: University of British Columbia
Year: 2009

description: The dissertation consists of two parts. In the first part we introduce and investigate a class of mixed Poisson regression models that include covariates in both mixing probabilities and Poisson rates. The proposed models generalize the usual Poisson regression in several ways, and can be used to adjust for extra-Poisson variation. The features of the models, identifiability, estimation methods based on the EM and quasi-Newton algorithms, properties of these estimates, model selection criteria and residual analysis are discussed. A Monte Carlo study investigates implementation and model choice issues. Several applications of this approach are analyzed. This analysis is compared to quasi-likelihood approaches. In the second part we introduce and investigate a class of mixed logistic regression models that include covariates in both mixing probabilities and binomial parameters with the logit link. The proposed models generalize the usual logistic regression in several ways, and can be used to adjust for extra-binomial variation. The features of the models, identifiability, estimation methods based on the EM and quasi-Newton algorithms, properties of these estimates, model selection criteria and residual analysis are discussed. A Monte Carlo study investigates implementation and model choice issues. An applications of this approach is analyzed and results compared to those by quasi-likelihood approaches. The dissertation also discusses future research in the areas and provides FORTRAN codes for all computations required to apply the models.

description: It has been established that Gamma-Ray Bursts (GRBs) are connected to Supernovae (SNe) explosions of Type Ib/c. We intend to test whether the hypothesis of Type Ib/c SNe from different massive progenitors can reproduce the local GRB rate as well as the GRB rate as a function of redshift. We aim to predict the GRB rate at very high redshift under different assumptions about galaxy formation and star formation histories in galaxies. We assume different star formation histories in galaxies of different morphological type: ellipticals, spirals and irregulars. We explore different hypotheses concerning the progenitors of Type Ib/c SNe. We find an excellent agreement between the observed GRB local rate and the predicted Type Ib/c SN rate in irregular galaxies, when a range for single Wolf-Rayet stars of 40-100 M_sun is adopted. We also predict the cosmic Type Ib/c SN rate by taking into account all the galaxy types in an unitary volume of the Universe and we compare it with the observed cosmic GRB rate as a function of redshift. By assuming the formation of spheroids at high redshift, we predict a cosmic Type Ib/c SN rate, which is always higher than the GRB rate, suggesting that only a small fraction (0.1-1 %) of Type Ib/c SNe become GRBs. In particular, we find a ratio between the cosmic GRB rate and the cosmic Type Ib/c rate in the range 0.001-0.01, in agreement with previous estimates. Finally, due to the high star formation in spheroids at high redshift, which is our preferred scenario for galaxy formation, we predict more GRBs at high redshift than in the hierarchical scenario for galaxy formation, a prediction which awaits to be proven by future observations.

description: The greatest human impact on the forest ecosystems such as loss of forest area, habitat fragmentation, and soil degradation leads to decline biodiversity. These impacts can be addressed by the integration of trees on the agricultural landscape and maintaining the existing forests. In order to determine woody species diversity and density of tree on farmland in relation to the altitudinal gradient, 75 sample quadrats having an area of 100 m × 50 m, 15 sample quadrats in each range of altitude were measured. The result indicates that a total of 42 woody species belongs to 23 families and Fabaceae were the dominant family. There was a significant difference (P < 0.05) in woody species diversity, richness, evenness, tree density and the basal area between the altitudinal gradient ranges. Woody species richness (4.00), diversity indexes (1.11) and tree density (21.34) were higher in the middle altitude (1500–2000 m a.s.l). However, woody species evenness index (0.91) and the basal area (0.80) were highest in the 2000–2500 and 2500–3000 m a.s.l, respectively. Acacia abyssinica subsp. Abyssinica, Croton macrostachyus, and Cordia Africana were found to have the highest IVI (importance value index). Boswellia papyrifera, Acacia abyssinica subsp. Abyssinica and Diospyros mespiliformis were found to have the highest density. It can be generally concluded that the indigenous agricultural practices have been one way of diversifying agroecosystem in a way that has positive effects on ecological stability and can conserve species diversity.

description: It is well known that non-local theories of gravity have been a flourish arena of studies for many reasons, for instance, the UV incompleteness of General Relativity (GR). In this paper we check the consistency of ST-homogeneous Gödel-type metrics within the non-local gravity framework. The non-local models considered here are ghost-free but not necessarily renormalizable since we focus on the classical solutions of the field equations. Furthermore, the non-locality is displayed in the action through transcendental entire functions of the d'Alembert operator $\Box$ that are mathematically represented by a power series of the $\Box$-operator. We find two exactly solutions for the field equations correspondent to the degenerate ($ω=0$) and hyperbolic ($m^{2}=4ω^2$) classes of ST-homogeneous Gödel-type metrics.

description: In this work, we present a federated version of the state-of-the-art Neural Collaborative Filtering (NCF) approach for item recommendations. The system, named FedNCF, enables learning without requiring users to disclose or transmit their raw data. Data localization preserves data privacy and complies with regulations such as the GDPR. Although federated learning enables model training without local data dissemination, the transmission of raw clients' updates raises additional privacy issues. To address this challenge, we incorporate a privacy-preserving aggregation method that satisfies the security requirements against an honest but curious entity. We argue theoretically and experimentally that existing aggregation algorithms are inconsistent with latent factor model updates. We propose an enhancement by decomposing the aggregation step into matrix factorization and neural network-based averaging. Experimental validation shows that FedNCF achieves comparable recommendation quality to the original NCF system, while our proposed aggregation leads to faster convergence compared to existing methods. We investigate the effectiveness of the federated recommender system and evaluate the privacy-preserving mechanism in terms of computational cost.

description: The Kraichnan flow provides an example of a random dynamical system accessible to an exact analysis. We study the evolution of the infinitesimal separation between two Lagrangian trajectories of the flow. Its long-time asymptotics is reflected in the multiplicative large deviation regime of the statistics of stretching exponents. In the flow in a two-dimensional periodic square where the anisotropy persists at small scales, the calculation of the large deviation rate function of the stretching exponents reduces to the study of the ground state energy of an integrable periodic Schroedinger operator of the Lame type. The underlying integrability permits to explicitly exhibit the non-Gaussianity of the multiplicative large deviations, to analyze the time-scales at which the large deviation regime sets in and to identify the general scenario for the appearance of multiplicative large deviations and the restrictions on its applicability.

description: As a rule, a quadratic functional depending on a great number of binary variables has a lot of local minima. One of approaches allowing one to find in averaged deeper local minima is aggregation of binary variables into larger blocks/domains. To minimize the functional one has to change the states of aggregated variables (domains). In the present publication we discuss methods of domains formation. It is shown that the best results are obtained when domains are formed by variables that are strongly connected with each other.

description: Dairy beverages are nutritious and also highly susceptible to bacterial contamination posing a threat to human health. In recent years, production and consumption of dairy beverages are rapidly increasing in Bangladesh; however, the presence of bacteria including human pathogens in commonly consumed dairy beverages has not been evaluated before. Here, we focused on microbiological quality of some dairy beverages available in Dhaka University campus. We examined 25 samples from five different items locally named as Lassi, Labang, Borhani, Pistachio nut sherbet, and Strawberry milkshake. Non-selective medium PCA and different selective agar media such as MacConkey, SS, EMB, and TCBS, and Cooked Meat were used for isolation. Antibiotic resistance was assessed by disk diffusion method against Ampicillin, Colistin, Ciprofloxacin, Levofloxacin, Ceftriaxon, and Gentamycin. In PCA medium, Labang and Strawberry milkshake, respectively, showed the highest (3.6 × 107 CFU/mL) and the lowest (1.76 × 103 CFU/mL) bacterial count. In MacConkey and EMB media, the highest bacterial growths were, respectively, shown by Pistachio nut sherbet (1.22 × 104 CFU/mL) and Lassi (2.96 × 103 CFU/mL) whereas no growth was observed for Borhani. Strawberry milkshake was found with the highest bacterial prevalence such as E. coli, Klebsiella, Proteus, Pseudomonas Bacillus, Micrococcus, and Streptococcus whereas Borhani and Labang contained the lowest variety of bacteria. Isolates such as Shigella, Aeromonas, Micrococcus, Bacillus, Streptococcus, and Proteus were multi-drug resistant to Ampicillin and Colistin. Findings indicated that examined samples contained health risk factor. Findings may help relevant stakeholders to consider food safety issues of dairy beverages during processing, marketing, and consumption.

description: In the noncommutative (Moyal) plane, we relate exact U(1) sigma-model solitons to generic scalar-field solitons for an infinitely stiff potential. The static k-lump moduli space C^k/S_k features a natural K"ahler metric induced from an embedding Grassmannian. The moduli-space dynamics is blind against adding a WZW-like term to the sigma-model action and thus also applies to the integrable U(1) Ward model. For the latter's two-soliton motion we compare the exact field configurations with their supposed moduli-space approximations. Surprisingly, the two do not match, which questions the adiabatic method for noncommutative solitons.

description: This article presents the results of experiments conducted on developing a new resource-saving method for producing quality seeds of the onion variety "Istiqbol" by leaving the bulbs in place and burying them. According to the research, the physiological processes in the onion bulbs did not stop, and due to the developed root system, the emergence of flower stalks, flowering time, and seed ripening period extended by 20-34 days compared to the control group. As a result, yields reached 532 kg on August 30, 515 kg on September 9, and 491 kg on September 19, which is 14.2-23.7% higher than the control variety.

description: The aim of this study was to investigate the response of soil microbial parameters to nutrient management practices involving organic amendments, farmyard manure (FYM), vermicompost (VC), crop residues (CR) and biofertilizers (BF) in rice–wheat and rice–wheat–mung bean cropping system of the Indo-Gangetic Plains, India. Soil microbial biomass C (Cmic), basal respiration, ergosterol, glomalin, soil enzymes (glucosidases, phosphatases and dehydrogenases), FDA activity, organic carbon (Corg), Cmic-to-Corg ratio and metabolic quotient (qCO2) were estimated in soil samples collected at 0–15 cm depth. The highest Corg (0.64%) and Cmic (103.8 μg g−1) soil levels occurred in the treatment receiving a combination of VC, CR and BF. Soil respiration, Corg and Cmic-to-Corg ratio were significantly enhanced by the input of CR to plots receiving FYM and VC. The qCO2 was the highest in plots receiving a combination of FYM, CR and BF followed by control (no nutrient input) and least in plots receiving a combination of VC, crop residue and biofertilizer. These results indicate that the organic practices involving VC, CR and BF improved soil microbial characteristics and Corg in rice–wheat systems.

description: Στην παρούσα έρευνα μελετήθηκε η επιρροή που ασκεί το χιούμορ στον εργασιακό χώρο στην προσαρμογή των νεοεισερχόμενων μελών σε έναν οργανισμό. Συγκεκριμένα, το εργασιακό χιούμορ όπως χρησιμοποιείται από τα καθιερωμένα μέλη του οργανισμού και κατά κύριο λόγο από τον άμεσα προϊστάμενο και τους συναδέλφους βρέθηκε να επηρεάζει θετικά την προσαρμογή των νεοεισερχόμενων και πιο ειδικά την κοινωνική αποδοχή τους. Επιπλέον, το χιούμορ βρέθηκε να επιδρά θετικά στην ταύτιση των νεοεισερχόμενων με τη σχέση που δημιουργούν με τον προϊστάμενο και τους συναδέλφους αντίστοιχα, και μέσω αυτής της διαδικασίας να αισθάνονται αρεστοί και αποδεκτοί από το νέο εργασιακό περιβάλλον. Επιβεβαιώθηκε, δηλαδή η βασική υπόθεση της έρευνας ότι το χιούμορ που χρησιμοποιούν είτε ο προϊστάμενος είτε οι συνάδελφοι μέσω της ταύτισης με τη σχέση με αυτούς αντίστοιχα, οδηγεί στην κοινωνική αποδοχή των νεοφερμένων. Η παρούσα εργασία συνεισφέρει στη κατανόηση της διαδικασίας κοινωνικοποίησης των νέων μελών του οργανισμού και στην επίδραση του εργασιακού χιούμορ στην κοινωνική αποδοχή τους μελετώντας τη προεξέχουσα θέση της ταύτισης με τη σχέση.
description: In this research, we studied the influence of humor in the workplace in the adjustment of newcomers in an organization. Specifically, humor in the workplace as used by the established members of the organization and primarily from the immediate supervisor and coworkers was found to positively influence the adjustment of newcomers and more specifically their social acceptance. Moreover, humor was found to positively influence the identification of new entrants to the relationship created with the supervisor and coworkers respectively, and through this process newcomers feel liked and accepted by the new working environment. This confirms the underlying assumption of the research that humor from either the supervisor or coworkers through relational identification with them respectively, leads to social acceptance of newcomers. This work contributes to the understanding of the socialization process of new members of the organization and the impact of humor in the workplace in social acceptance, studying the prominence of the relational identification.

description: In this paper, we propose and study a hybrid mechanism for coherent transmission of photons in the coupled resonator optical waveguide (CROW) by incorporating the electromagnetically induced transparency (EIT) effect into the controllable band gap structure of the CROW. Here, the configuration setup of system consists of a CROW with homogeneous couplings and the artificial atoms with $Λ$-type three levels doped in each cavity. The roles of three levels are completely considered based on a mean field approach where the collection of three-level atoms collectively behave as two-mode spin waves. We show that the dynamics of low excitations of atomic ensemble can be effectively described by an coupling boson model. The exactly solutions show that the light pulses can be stopped and stored coherently by adiabatically controlling the classical field.

description: The aim of the present thesis was to study the perspective of English Language and Literature teachers, as well as parents of students, on the work that public elementary schools and private language schools offer for learning English in the “Basic User” level. The thesis consisted of two parts: the theoretical and the empirical. In the first part, which covered the theoretical part, there was a brief presentation of the English language internationally, followed by a review of the teaching of foreign languages and teaching theories. Finally, there was a reference in the English language generally in Greek education and more specifically in Greek private education. In the empirical part, we cited the origin, objectives, research questions, methodology and analysis of the research data. This was followed by a discussion of the findings of the research and the bibliography.

description: We investigated the effects of increasing physical activity (PA) and reducing sedentary behaviour (SB) of mental health professionals on their attitudes towards and practices in recommending more PA and less SB to their clients. A 4-week pre-post intervention trial was conducted involving 17 mental health professionals. The participants who increased their own physical activity during the intervention increased the frequency of recommending more PA (p = 0.009) and less SB (p = 0.005) to their clients. A relatively simple, low-cost intervention, consisting of group behaviour change counselling, goal setting and positive feedback, may improve the practices of mental health professionals.

description: The increasing penetration of technology in our student’s lives and the advent of leisure

computing among students of AU creates a fertile environment for successful thriving of an

online based food ordering system. AU Food Court is an application designed primarily for use

among Amity University Students. The system will allow food vendors to showcase their

daily menu, which will enable users to quickly and easily scan through an online menu which

they can use to place orders with just a few clicks. The respective administrators of each food

vendor on the platform can then use these orders through an easy to navigate graphical user

interface for efficient processing. The application provides convenience for the users. The online

food ordering app sets up menus online and the customers easily place the order with a simple

click. Also, with a food menu online you can easily track the orders, maintain the customer's

database and improve the food delivery service. This system allows the user to select the desired

food items from the displayed menu. The user orders the food items. The user’s data is

maintained with confidentiality as the system has a separate account for each user. An id and

password are provided for each user. Therefore, it provides a more secure ordering.
Optimal two-qubit gate for generation of random bipartite entanglement

description: We numerically study protocols consisting of repeated applications of two qubit gates used for generating random pure states. A necessary number of steps needed in order to generate states displaying bipartite entanglement typical of random states is obtained. For generic two qubit entangling gate the decay rate of purity is found to scale as $\sim n$ and therefore of order $\sim n^2$ steps are necessary to reach random bipartite entanglement. We also numerically identify the optimal two qubit gate for which the convergence is the fastest. Perhaps surprisingly, applying the same good two qubit gate in addition to a random single qubit rotations at each step leads to a faster generation of entanglement than applying a random two qubit transformation at each step.
