Monographische Bearbeitung der Serpulidae (Polychaeta sedentaria) aus dem Cenoman (Oberkreide) am Südwestrand des Münsterländer Beckens

Auf Grund erkannter Mängel wurden Systematik und Taxonomie der fossilen Serpuliden einer Revision unterzogen. Ausgehend von zoologischen Untersuchungen wurden neue Kriterien für eine Beurteilung von fossilen Serpuliden geschaffen. Der Schwerpunkt liegt dabei auf einem direkten Vergleich zwischen rezenten und fossilen Formen. Als Fossilmaterial dient eine der reichsten bekannten fossilen Serpulidenfaunen, die aus dem Unter- und Mittelcenoman des SW-Teils des Münsterländer Beckens stammt. In einem ökologischen Teil konnte nachgewiesen werden, daß die sehr reichhaltige Begleitfauna und -flora in strandnahen Flachwasserbereichen mit tropischen bis subtropischen Klimabedingungen gelebt haben. 12 verschiedene Biotope wurden auf ihre Serpulidengemeinschaften hin untersucht. Da Serpuliden Fazies-Fossilien sind, ist ihr stratigraphischer Wert gering. In einem systematischen Teil werden insgesamt 69 Serpulidenarten beschrieben. Dabei konnten 2 neue Gattungen, eine neue Untergattung und 30 neue Arten aufgestellt werden. 7 neue Arten werden unter offener Nomenklatur beschrieben. Durch umfangreiche morphologische Untersuchungen und umfassende Vergleiche mit rezentem Material konnten viele Arten und Gattungen revidiert und ihre verwandtschaftlichen Beziehungen geklärt werden. Es konnte wahrscheinlich gemacht werden, daß von mindesten 13 Gattungen, die ursprünglich nach rezentem Material aufgestellt wurden, in der Oberkreide bereits Arten auftreten. Erstmals in der europäischen Kreide konnte die tertiäre Gattung Paliurus Gabb beobachtet werden.
Low-Complexity Numerical Methods for Nonlinear Model Predictive Control

This thesis presents a novel low-complexity method for the solution of the nonlinear optimization programs arising in Model Predictive Control problems. The optimization method consists of taking a gradient step and projecting it onto a linearization of the constraints around the current iterate. Since this approach does not fall into any of the standard optimization methods, we develop the convergence theory and design numerical algorithms to solve a generic optimization problem. We present several theoretical results. The conceptually simplest implementation of the proposed method is only locally convergent to a local minimum under some technical assumptions. A modification to the method is considered in order to obtain global convergence to a critical point of the problem, i.e., a point satisfying first-order optimality conditions. This is achieved by considering merit functions, whose optimality conditions can be related to the optimality conditions of the original optimization problem. The method introduced in this thesis is particularly efficient for nonlinear Model Predictive Control problems. In fact, for a specific class of nonlinearly constrained optimization programs and via the introduction of appropriately defined slack variables, the projection onto the linearization of the constraints becomes computationally cheap to evaluate. As a result, the complexity of the method is lower than other typical optimization methods applied to the same problem, since it is only linear in the prediction horizon and quadratic in the state and input dimension. We provide the automatic C code generation tool FalcOpt (First-order Algorithm via Linearization of Constraints for OPTimization) to solve custom Model Predictive Control problems via the proposed numerical algorithms. Several applications are presented for the proposed method, ranging from industrial centrifugal compression systems to power electronics. We observe that a small number of iterations is typically sufficient to yield an acceptable level of suboptimality. Therefore, the method is particularly aimed at time-critical applications. Furthermore, its capability to deal efficiently with single precision makes it suited for use on embedded devices.
An extension of the directed search domain algorithm to bilevel optimization

ABSTRACT A method is developed for generating a well-distributed Pareto set for the upper level in bilevel multiobjective optimization. The approach is based on the Directed Search Domain (DSD) algorithm, which is a classical approach for generation of a quasi-evenly distributed Pareto set in multiobjective optimization. The approach contains a double-layer optimizer designed in a specific way under the framework of the DSD method. The double-layer optimizer is based on bilevel single-objective optimization and aims to find a unique optimal Pareto solution rather than generate the whole Pareto frontier on the lower level in order to improve the optimization efficiency. The proposed bilevel DSD approach is verified on several test cases, and a relevant comparison against another classical approach is made. It is shown that the approach can generate a quasi-evenly distributed Pareto set for the upper level with relatively low time consumption.
Dynamics of the Float-Counterweight Type Wave Power Generation System

The dynamics of a wave power generation system which consists of wire(s), float(s), counterweight(s) and ratchet mechanism is examined in this paper. The model is composed of the several equations: the equation for the generator, the equation for the float and counterweight motion, the equation for the driving pulley motion. The hydrodynamic excitation force is calculated numerically along with the added mass force and damping force, which are then combined with the equation for float motion given by the rigid body dynamics to obtain the float displacement and other physical quantities. Wave tank test results are found to agree closely with the numerical results, thereby validating the proposed numerical model. Key physical quantities, electrical power output and maximum wire tension, are examined for different wave conditions.
E-banking quality and customer loyalty: The mediating role of customer satisfaction

Attaining customer satisfaction and loyalty is seen as a prerequisite for successful bank management. The purpose of the study is to identify and explain the mechanism through which e-banking quality is related to loyalty by including satisfaction as a mediating variable in South Africa. The study adopts a descriptive research design and a quantitative mediation analysis. The data collected through SurveyMonkey comprised a sample of 310 participants who used online banking. The results of the mediation analysis confirm that e-banking quality has a considerable and positive effect on customer satisfaction, which in turn has a significant and positive effect on loyalty in e-banking. The direct effect of e-banking quality on loyalty is also confirmed. Furthermore, the study’s findings show that the quality of e-banking has a significant and favorable indirect effect on loyalty, as mediated by customer satisfaction. Because the direct effect of e-banking quality on loyalty remained significant after the satisfaction intervention/mediation in the model, the mediation is regarded as partial. The findings of this study offer essential marketing guidance for banking professionals who design and implement e-banking solutions for their customers.
Somatotypes of Top Croatian Male Volleyball Players

Situational efficiency of volleyball players depends on many factors, including specific ones in the area of morphology. The specialization of playing roles implies the performance of specific motor tasks, and therefore a specific combination of morphological factors necessary for the player’s efficiency. This study aimed to determine the somatotypes of groups of top-level volleyball players divided according to their playing role. The research was conducted on 40 (body height 192.22±8.58 cm, body weight 86.93±11.22 kg, age 24.18±4.97 years) male volleyball players from the Croatian A1 volleyball league. According to the playing role, 10 setters (body height 191.21±6.39 cm, body weight 84.12±8.76 kg, age 24.12±6.77 years), 10 middle blockers (body height 199.97±4.41 cm, body weight 94.82±6.67 kg, age 26.05±26.05 years), 10 liberos (body height 181.71±5.71 cm, body weight 74.97.21±5.59 kg, age 22.67±2.88 years) and 10 outside hitters (body height 196.06±4.34 cm, body weight 93.80±10.29 kg, age 23.89±5.53 years). Heath-Carter method was used for the somatotype determination. A statistically significant difference between the groups was detected in Body height, Body weight, Flexed arm girth circumference, Flexed calf girth circumference and Calf skinfold. The determined somatotypes for setters (2.8 - 3.8 - 3.4) and middle blockers (2.3 - 3.8 - 3.6) are mesomorph-ectomorph, and liberos (2.4 - 4.6 - 3.0) and outside hitters (2.5 - 4.3 - 3.1) are ecto-mesomorph. The results are in line with previous research. This confirms the importance of the longitudinal dimensionality of the skeleton in volleyball. In the future, we can expect the growth of the ectomorph component, with a stagnation or slight increase in the mesomorph component of the somatotype in top level volleyball.
Intergenerational Differences in Communication Processes with the Homeland: Turkish Immigrants Living in Australia

The focus of this study is the first-generation Turkish immigrants who went to Australia to work after the bilateral agreement signed between Australia and Turkey in 1968 and their second and third generation relatives. The objective is to reveal the communication processes of different generations of Turkish immigrants living in Australia with Turkey in terms of transnationalism. The research was designed as a holistic single case study in accordance with the qualitative method. Accordingly, triangulation was ensured by using data collection tools such as online observation, semi-structured interviews and participant observation. The field research was carried out in Sydney, Australia between September 2018 and January 2019. During the research, semi-structured interviews were held with 30 participants who were reached by snowball sampling. Of the 30 participants, 14 are from the first generation, 13 are from the second generation and 3 are from the third generation. Findings show that the means of communication and engagement with their homeland, which have evolved significantly since the beginning of Turkish immigration to Australia, directly affected the migrants' lives. Additionally, it has been observed that transnational ties are strengthened by the choice of communication tools that provide instant communication. It was also revealed that the developing technology and historical conditions had different effects on different generations of migrants.
ASSESSMENT OF THE CONTRIBUTIONS OF SMALL-SCALE BROILER PRODUCTION TO FARMERS’ FOOD SECURITY IN KADUNA STATE, NIGERIA

The challenges of food insecurity and hunger in Nigeria have continued to receive attention from experts and the government. To increase both protein intake and food security, the government called for urgent need to increase broiler production at both household and commercial holdings. Primary data obtained in year 2020, from 205 randomly selected broiler farmers was analyzed using descriptive statistics and Tobit regression model. This study assessed small-scale broiler production’s contribution to farmers’ food security in Kaduna state, Nigeria. The result showed that mean age was 40 years and majority of the farmers (89.4%) had household size ranged from 1 – 10 persons. In addition, about 73.8% were members of a cooperative society, about 40.5% of the farmers did not have access to extension service while about 78 % of the farmers have access to credit. About 75.10 percent of broiler farming households were found to be food secure. Of the food insecure households, 6.70 % were marginally food insecure, 4.20 % moderately food insecure and 14.00 % severely food insecure. The regression results showed that coefficients of level of education (0.872), access to credit (0.113), membership of association (0.068), cost of day-old chicks (0.363), cost of feed (0812), cost of labour (-2.211), cost of drugs (-0.263) and income from broiler (0.161) were found to be significant contributing to the food security status of the broiler farming households. Finally, broiler farmers attested to the fact that; lack of constant market (95.8%), high cost of feed (92.7%), high cost of input (88%), and price fluctuations (86.9%) are most severe constrains militating the chances of increasing broiler production. Built on the findings of the study it can be concluded that the proportion of food secure broiler farmers are more than the food insecure broiler farmers in the study area. Education, cost of feed and income from broiler production are variables that significantly influences broiler farmers’ food security status. Therefore, farmers should adopt self-feed formulation using locally available resources that will reduce the cost of feeding and increase their profit margin and thereby their food security status.
New physics from a natural electroweak symmetry breaking

Despite its impressive success, the standard model of particle physics does not account for every experimental observations.In addition, it has some theoretical puzzles in its formulation that seem to require more fundamental explanations.Then, instead of an ultra-violet complete theory, the standard model should rather be viewed as an effective description of a more fundamental theory and new physics should be introduced.We follow two different approaches of new physics.In the first one, we extend the standard model by only few new states assuming that the heavier states are decoupled from the electro-weak scale.This approach is mostly phenomenological as by hypothesis the extensions that we consider are a low energy manifestation of a more complete theory.We particularly focus on new fermions as they are a common prediction of a lot of well-motivated beyond the standard model theories.The main purpose is to study the effect of these new fermions in light of the recent Higgs couplings measurements. %The second approach has a more theoretical origin and is based on an ultra-violet complete theory.We focus on composite Higgs models that aim to solve one theoretical puzzle of the standard model, that is, the hierarchy problem of the electro-weak scale.The composite Higgs paradigm being realised by a new strongly interacting sector made of new fundamental fermions, we study the non-perturbative dynamics using the Nambu and Jona-Lasinio model.We derive for instance the spectrum of the lightest resonances which could be observed in a near future at the LHC or at some other colliders.
Ergodic and outage capacity for Ricean fading channel with shadow fading on high-speed railway

In this paper, we discuss the channel characteristics on high-speed railway and discuss the ergodic and outage capacity for Ricean channel with shadow fading. The impacts of dynamic K factor on ergodic and outage capacity are evaluated too. Simulation results show both shadow fading and dynamic K factor have significant impact on outage capacity, but little impact on ergodic capacity.
INDONESIAN ECONOMIC DEMOCRACY: DEBATES, CHALLENGES AND OPPORTUNITIES DEMOKRASI EKONOMI INDONESIA: PERDEBATAN, TANTANGAN DAN PELUANG

The Pancasila Economic Democracy's adoption encountered significant cultural and psychological barriers. Democratic economic models have not yet produced sufficient outcomes. Contrarily, liberal capitalistic democracy is being practiced in this context. This article discusses Economic Democracy as Indonesia’s economic system. This research is a library with a descriptive approach that collects documentation data from various articles and books and analyzed it through content analysis. This research’s results must balance planning between national and decentralization levels in implementing economic activities to reach economic and social justice. In addition, Indonesia can also build a more rational foundation of the peculiarities of economic activity so that it is not limited to religious values but involves cognitive awareness to realize ideals as stated in the Preamble of the UUD 1945. Current capability is viewed as a deficit that could become a tremendous strength in the future so that individuals will not be frightened of being different or taking risks.
Risk Factors for Dengue Shock Syndrome in Children Admitted in Federal Govt. Polyclinic Hospital (FGPC) Islamabad

Objective: To determine the risk factors for dengue shock syndrome in children admitted in Federal Govt. Polyclinic Hospital (FGPC) Islamabad. Methodology: A cross sectional study, conducted at Pediatric department of FGPC hospital from August 2019 to October 2019, included 102 children of less than 12 years of age. All the children with acute febrile illness, who tested positive for NS1 antigen visiting the outpatient and emergency department, admitted in Pediatric department were considered eligible for enrollment in the study. Demographic and clinical characteristics were reported and correlated with disease prognosis and clinical outcomes. Results: Out of 102 patients, 13 (12.7%) developed dengue shock syndrome (DSS). Patients with capillary refill time of more than 3 seconds were found to be 2.44 times more likely to develop dengue shock syndrome (OR=2.44, 95% CI 1.47 – 4.03, p<0.001). Similarly, patients with thrombocytopenia (platelet count less than 150x103 cells) and leukopenia (TLC less than 4000x103 cells) were found to be at increased risk of developing dengue shock syndrome as compared to others (OR=1.28, 95% CI 1.12 – 1.48, p=0.001 and OR=1.6, 95% CI 1.12 – 5.21, p=0.01 respectively). Out of 13(12.7%) patients with DSS 1 patient (7.7%) died but no mortality observed in DHF. Conclusion: Increased capillary refill time, thrombocytopenia, and leukopenia were found to be significant predictors of DSS in children with dengue fever. Early identification of these risk factors can help in timely management and potentially reduce morbidity and mortality associated with DSS.
Gender diversity in municipal governmental bodies and budgetary solvency

Diverse research has analysed the effects of gender in government on public budgetary outcomes using the gender bias approach – gender trait –; however, studies evaluating the gender effects of municipal governments on budgetary solvency using a gender balance approach – gender diversity – are scarce. Our objective was to determine whether gender diversity in Spanish municipal governments affects institutional budgetary solvency, taking into account that the mayor’s gender and the ideology of the government could impede visualizing the effects of diversity because they create heterogeneity. Using both static and dynamic panel data models on a sample of Spanish municipalities with more than 20,000 inhabitants, we found that gender diversity has a positive effect on budgetary solvency when the municipality has a male mayor. However, the effect of gender diversity is negative if the mayor is a woman, which could be explained by the different arguments provided by social identity or social categorization theories. Diversas investigaciones han analizado los efectos del género en el gobierno sobre los resultados presupuestarios públicos utilizando el enfoque de sesgo de género – rasgo de género –; sin embargo, los estudios que evalúan los efectos del género de los gobiernos municipales sobre la solvencia presupuestaria usando un enfoque de equilibrio de género – diversidad de género – son escasos. Nuestro objetivo es conocer si la diversidad de género en los gobiernos municipales españoles afecta a la solvencia presupuestaria institucional, teniendo en cuenta que el género del alcalde y la ideología del gobierno podrían impedir visualizar los efectos de la diversidad, porque generan heterogeneidad. Utilizando tanto un modelo estático como uno dinámico de datos de panel en una muestra de municipios españoles de más de 20.000 habitantes, nuestro principal hallazgo es que la diversidad de género tiene un efecto positivo en la solvencia presupuestaria cuando el municipio tiene un alcalde. Sin embargo, el efecto de la diversidad de género tiene un impacto negativo si el gobierno municipal está encabezado por una alcaldesa, lo que podría encontrar su explicación en diferentes argumentos aportados por las teorías de la identidad social o de la categorización social.

Stability, bifurcation analysis and chaos control for a predator-prey system

We study qualitative behavior of a modified prey–predator model by introducing density-dependent per capita growth rates and a Holling type II functional response. Positivity of solutions, boundedness and local asymptotic stability of equilibria were investigated for continuous type of the prey–predator system. In order to discuss the rich dynamics of the proposed model, a piecewise constant argument was implemented to obtain a discrete counterpart of the continuous system. Moreover, in the case of a discrete-time prey–predator model, the boundedness of solutions and local asymptotic stability of equilibria were investigated. With the help of the center manifold theorem and bifurcation theory, we investigated whether a discrete-time model undergoes period-doubling and Neimark–Sacker bifurcation at its positive steady-state. Finally, two novel generalized hybrid feedback control methods are presented for chaos control under the influence of period-doubling and Neimark–Sacker bifurcations. In order to illustrate the effectiveness of the proposed control strategies, numerical simulations are presented.
