description: In this paper we propose an iterative method to address the face identification problem with block occlusions. Our approach utilizes a robust representation based on two characteristics in order to model contiguous errors (e.g., block occlusion) effectively. The first fits to the errors a distribution described by a tailored loss function. The second describes the error image as having a specific structure (resulting in low-rank in comparison to image size). We will show that this joint characterization is effective for describing errors with spatial continuity. Our approach is computationally efficient due to the utilization of the Alternating Direction Method of Multipliers (ADMM). A special case of our fast iterative algorithm leads to the robust representation method which is normally used to handle non-contiguous errors (e.g., pixel corruption). Extensive results on representative face databases (in constrained and unconstrained environments) document the effectiveness of our method over existing robust representation methods with respect to both identification rates and computational time.

description: The Hikurangi Subduction Zone (HSZ), New Zealand, accommodates westward subduction of the Pacific Plate. Where imaged seismically, the shallow HSZ décollement (<10–15 km depth) occurs within or along the upper contact of Late Cretaceous-Paleogene (70–32 million-year-old) sediments. The frictional properties of Paleogene sediments recovered from Ocean Drilling Program Leg 181, Site 1124 were measured at 60 MPa effective normal stress and varying sliding velocities (V = 0.3–30 µm/s) and temperatures (T = 25–225 °C). Velocity-stepping experiments were conducted at temperatures of 25 °C, 75 °C, 150 °C, and 225 °C to determine the friction rate parameter (a–b). Paleocene and Oligocene clay-bearing nannofossil chalks (μ = 0.45–0.61) and a middle Eocene clayey nannofossil chalk (μ = 0.35–0.51) are frictionally stronger than smectite-bearing Eocene clays (μ = 0.16–0.31). With increasing temperature, chalks show rate-strengthening to rate-weakening frictional stability trends; clays show rate-weakening and rate-neutral to rate-strengthening frictional stability trends. The results obtained from Site 1124 sediments indicate that: (1) fault-zone weakness may not require pore-fluid overpressures; (2) clays and chalks can host frictional instabilities; and (3) heterogeneous frictional properties can promote variable slip behaviour.

description: Scattered data interpolation schemes using kriging and radial basis functions (RBFs) have the advantage of being meshless and dimensional independent, however, for the data sets having insufficient observations, RBFs have the advantage over geostatistical methods as the latter requires variogram study and statistical expertise. Moreover, RBFs can be used for scattered data interpolation with very good convergence, which makes them desirable for shape function interpolation in meshless methods for numerical solution of partial differential equations. For interpolation of large data sets, however, RBFs in their usual form, lead to solving an ill-conditioned system of equations, for which, a small error in the data can cause a significantly large error in the interpolated solution. In order to reduce this limitation, we propose a hybrid kernel by using the conventional Gaussian and a shape parameter independent cubic kernel. Global particle swarm optimization method has been used to analyze the optimal values of the shape parameter as well as the weight coefficients controlling the Gaussian and the cubic part in the hybridization. Through a series of numerical tests, we demonstrate that such hybridization stabilizes the interpolation scheme by yielding a far superior implementation compared to those obtained by using only the Gaussian or cubic kernels. The proposed kernel maintains the accuracy and stability at small shape parameter as well as relatively large degrees of freedom, which exhibit its potential for scattered data interpolation and intrigues its application in global as well as local meshless methods for numerical solution of PDEs.

Year: 2009

description: This paper answers a speciific research question: whether the child effect on mothers' employment diverged at the turn of the 21st century such that the effect of higher order births on employment became increasingly negative. In other words, did women with multiple children become even less likely to work during the economic recession of the early 2000s relative to women with only one child? I use Current Population Survey data from 1980 through 2007 to show that, indeed, relative to women with only one child in their family, the effect on employment of having multiple children became significantly more negative at the turn of the 21st century. The results detailed below underscore the importance of incorporating a measure of the number of children present when examining trends in women's work behaviors and they indicate that there is a lot to be learned from studying family and work behaviors during times of economic recession.
Novel Radio-Frequency Devices and Systems for Wearable Electronics and Wireless Power Transfer

description: Wearable and implantable systems have transformed the way we monitor and interact with our bodies. These systems are designed to be seamlessly integrated into daily life and have the potential to provide valuable health information to patients and healthcare providers. With the aging population, there is a growing need for remote monitoring and diagnostics, making wearable and implantable systems increasingly important. However, current wearable and implantable systems have limitations, such as the need for batteries or wire connections, which can make the devices bulky and uncomfortable. The use of rigid circuit components can also restrict the application of these systems. Therefore, there is a need for alternative approaches to improve the performance, versatility, and wearing comfort of these systems. In this dissertation, our primary objective is to address the prevalent constraints in wearable and implantable systems. Specifically, our approach leverages harmonic re-radiation and parity-time symmetry to develop wireless and fully passive systems that are compatible with soft nanomaterials such as silver nanowires and liquid metal. We present a series of innovative biomedical systems, including a breathable, reusable and zero-power smart face mask for wireless cough and mask-wearing monitoring, as well as multimodal wireless wound sensors for monitoring wound healing process. Additionally, we explore multi-band parity-time-symmetric wireless power transfer systems for bio-implantable applications, and an ultra-sensitive sensing mechanism grounded in parity-time-reciprocal scaling symmetry. The proposed systems are characterized by their compactness, light weight, battery-free nature, multiplexing capacity, and sensitivity, possessing the capability to meet the demands of healthcare internet-of-things applications. We envision that these systems hold great potential as promising solutions for next-generation wireless wearable devices and smart health monitoring systems.

Eastern American Correspondents and the Othering of Mexicans in the Nineteenth-century Popular Press
Creators: name: Fuhlhage, Michael J.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: American correspondents from distinct regions of the United States brought the cultural strains of those regions with them to areas of the West long settled by Mexicans. This dissertation demonstrates the role these distinct cultural strains played in generating stereotypical notions about Mexicans that reflected American settlers' material needs -- rooted in the doctrine of Manifest Destiny -- and conditioned correspondents to project the inverse of their core values onto Mexicans. As Mexicans from distinct regions of the Southwest were racialized and stripped of their individual distinctiveness in the white Anglo-Saxon mind, regionally specific othering that played a part in the process of Latinos' subordination merged into nationally known stereotypes that have prevailed since the turn of the twentieth century. This dissertation uses the methods of cultural history to examine the ways correspondents' religious and political beliefs, first-hand and second-hand knowledge about Mexicans, and personal trajectories combined to generate media images that othered Mexicans. This othering during the nineteenth century laid the foundations for stereotyping about Latinos in the twentieth century.
O docudrama brasileiro: Cidade de Deus, Carandiru e Tropa de Elite

Year: 2009

description: This dissertation examines the fiction films Cidade de Deus (2002), Carandiru (2003) and Tropa de elite (2007) that can be read as docudramas. With the blend of characteristics taken from documentaries of social representation and melodrama, docudrama claims proximity to actuality and contributes to a new interpretation and representation of events in a given society. Therefore, there is a higher responsibility to accuracy and to truth than in fiction films. To understand the term docudrama the work of Steven Lipkin is studied. Chapter 1 proposes the definition of the term docudrama based on a historical survey of documentary. Chapter 2 contextualizes and discusses the films and their literary sources Cidade de Deus (1997), Estação Carandiru (1999) and Elite da tropa (2005), within the history of Brazilian film industry and its relationship to Cinema Novo. Finally, chapter 3 addresses the relationship between Brazilian cinema and the popular culture phenomenon in the Brazilian social and economic contexts.

An equivariant embedding of quasi-regular Sasakian manifold is also derived.

description: Researchers have suggested that students referred to special education services for specific learning disabilities also experience reading difficulties. Research also suggests that students who experience reading difficulties also tend to have low reading and achievement motivation scores. This study examined the effects of a web-based publishing website Voice Thread have on student reading and achievement motivation. The study specifically addressed two questions. The first question: will students' reading motivation improve after participating in a Voice Thread web-based publishing project? The second question: What aspects of the technology used during the Voice Thread project will students perceive as positively impacting their reading motivation? Findings indicated that through participation in the web-based publishing projects student reading motivation increased. Additionally common themes were established and highlighted as a result of student responses according to the specific aspects of technology that helped increase their motivation.

description: Both the original Temperley-Lieb algebras $\mathsf{TL}_{n}$ and their dilute counterparts $\mathsf{dTL}_{n}$ form families of filtered algebras: $\mathsf{TL}_{n}\subset \mathsf{TL}_{n+1}$ and $\mathsf{dTL}_{n}\subset\mathsf{dTL}_{n+1}$, for all $n\geq 0$. For each such inclusion, the restriction and induction of every finite-dimensional indecomposable module over $\mathsf{TL}_{n}$ (or $\mathsf{dTL}_{n}$) is computed. To accomplish this, a thorough description of each indecomposable is given, including its projective cover and injective hull, some short exact sequences in which it appears, its socle and head, and its extension groups with irreducible modules. These data are also used to prove the completeness of the list of indecomposable modules, up to isomorphism. In fact, two completeness proofs are given, the first is based on elementary homological methods and the second uses Auslander-Reiten theory. The latter proof offers a detailed example of this algebraic tool that may be of independent interest.

description: Quantum annealing provides a way of solving optimization problems by encoding them as Ising spin models which are implemented using physical qubits. The solution of the optimization problem then corresponds to the ground state of the system. Quantum tunnelling is harnessed to enable the system to move to the ground state in a potentially highly non-convex energy landscape. A major difficulty in encoding optimization problems in physical quantum annealing devices is the fact that many real world optimization problems require interactions of higher connectivity as well as multi-body terms beyond the limitations of the physical hardware. In this work we address the question of how to implement multi-body interactions using hardware which natively only provides two-body interactions. The main result is an efficient circuit design of such multi-body terms using superconducting flux qubits in which effective N-body interactions are implemented using N ancilla qubits and only two inductive couplers. It is then shown how this circuit can be used as the unit cell of a scalable architecture by applying it to a recently proposed embedding technique for constructing an architecture of logical qubits with arbitrary connectivity using physical qubits which have nearest-neighbor four-body interactions. It is further shown that this design is robust to non-linear effects in the coupling loops as well as mismatches in some of the circuit parameters.

description: It was recently shown [G. Albareda, et al., Phys. Rev. Lett. 113, 083003 (2014)] that within the conditional decomposition approach to the coupled electron-nuclear dynamics, the electron-nuclear wave function can be exactly decomposed into an ensemble of nuclear wavepackets effectively governed by nuclear conditional time-dependent potential-energy surfaces (C-TDPESs). Employing a one-dimensional model system we show that for strong nonadiabatic couplings the nuclear C-TDPESs exhibit steps that bridge piecewise adiabatic Born-Oppenheimer PESs. The nature of these steps is identified as an effect of electron-nuclear correlation. Furthermore, a direct comparison with similar discontinuities recently reported in the context of the exact factorization framework allows us to draw conclusions about the universality of these discontinuities, viz. they are inherent to all nonadiabatic nuclear dynamics approaches based on (exact) time-dependent potential energy surfaces.

We study the semigroup $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$ of monotone injective partial selfmaps of $\mathbb{N}^{2}_{\leqslant}$ having cofinite domain and image. We describe properties of elements of the semigroup $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$ as monotone partial bijections of $\mathbb{N}^{2}_{\leqslant}$ and show that the group of units of $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$ is isomorphic to the cyclic group of order two. Also we describe the subsemigroup of idempotents of $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$ and the Green relations on $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$. In particular, we show that $\mathscr{D}=\mathscr{J}$ in $\mathscr{P\!O}\!_{\infty}(\mathbb{N}^2_{\leqslant})$.

description: AbstractWhile the field of youth citizenship has grown in recent years, many ‘gaps’ still exist. This commentary paper takes a critical look at three of these gaps in youth citizenship studies, namely (i) the Global North/Global South gap in understandings about youth citizenship, (ii) the citizenship status and empowerment gap, and (iii) the citizenship opportunity and participation gap. The paper argues that unless these gaps are attended to, we have a distortion in what we know about youth citizenship as the understandings and young people profiled (predominantly the Global North, elite, White and well resourced) represent only a small subsection of the whole, thus ignoring the experiences, knowledge, stories and voices of many diverse young citizens.
Elucidating the roles of the cardiogenic factors TBX20, TBX5 and HSP27 in vertebrate heart development
Creators: name: Brown, Daniel DeWitt
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The development of a functional multi-chambered contractile heart from a simple patterned tube involves a number of interacting transcriptional networks acting within well-defined temporal and spatial parameters. While many of the regulatory transcription factors have been identified and shown to be required for proper cardiogenesis, much remains to be deciphered regarding how these pathways interact at different times and within different cell populations during cardiogenesis. In addition, very little is currently known as to the specific downstream pathways affected by the various transcriptional regulators known to be involved in cardiac morphogenesis. In this dissertation, I describe the identification of several novel Xenopus laevis (X. laevis) genes expressed during heart development, including T-box 20 (Tbx20), titin novex 3 (XTn3), and heat shock protein 27 (XHsp27), thus providing evidence that these genes may be involved in cardiogenesis. By depleting X. laevis embryos of TBX20 and the related T-box protein, TBX5, I demonstrate that these proteins are both critical for proper cardiac morphogenesis. In addition, I provide evidence for a physical and functional interaction between TBX20 and TBX5 in cardiogenesis, thus adding one potential point at which multiple pathways may converge during heart development. Results from a microarray-based screen I conducted to identify genes downstream of Tbx5 function led to the identification of several cell cycle genes putatively misregulated in response to loss of TBX5. This work led directly to a study conducted by Sarah Goetz in which she has demonstrated a requirement for Tbx5 for proper cell cycle progression, thus further elucidating downstream pathways in heart development. A similar screen I performed to identify genes misregulated in response to loss of Tbx20 yielded a host of novel cardiac-specific genes, setting up the basis for future studies to come. This microarray experiment further resulted in the identification of Hsp27, which I subsequently demonstrated is required for proper fusion of cardiac precursors and for actin cytoskeleton integrity. Thus, this dissertation significantly advances our understanding of cardiogenesis at multiple levels, including the identification of factors involved in cardiogenesis, interactions between these factors, and downstream cellular behaviors affected by these factors.

description: This paper introduces a data-adaptive non-parametric approach for the estimation of time-varying spectral densities from nonstationary time series. Time-varying spectral densities are commonly estimated by local kernel smoothing. The performance of these nonparametric estimators, however, depends crucially on the smoothing bandwidths that need to be specified in both time and frequency direction. As an alternative and extension to traditional bandwidth selection methods, we propose an iterative algorithm for constructing localized smoothing kernels data-adaptively. The main idea, inspired by the concept of propagation-separation (Polzehl and Spokoiny 2006), is to determine for a point in the time-frequency plane the largest local vicinity over which smoothing is justified by the data. By shaping the smoothing kernels nonparametrically, our method not only avoids the problem of bandwidth selection in the strict sense but also becomes more flexible. It not only adapts to changing curvature in smoothly varying spectra but also adjusts for structural breaks in the time-varying spectrum.

description: Reaching population immunity against COVID-19 is proving difficult even in countries with high vaccination levels. Thus, it is critical to identify limits of control and effective measures against future outbreaks. The effects of nonpharmaceutical interventions (NPIs) and vaccination strategies are analyzed with a detailed community-specific agent-based model (ABM). The authors demonstrate that the threshold for population immunity is not a unique number, but depends on the vaccination strategy. Prioritizing highly interactive people diminishes the risk for an infection wave, while prioritizing the elderly minimizes fatalities when vaccinations are low. Control over COVID-19 outbreaks requires adaptive combination of NPIs and targeted vaccination, exemplified for Germany for January–September 2021. Bimodality emerges from the heterogeneity and stochasticity of community-specific human–human interactions and infection networks, which can render the effects of limited NPIs uncertain. The authors' simulation platform can process and analyze dynamic COVID-19 epidemiological situations in diverse communities worldwide to predict pathways to population immunity even with limited vaccination.
Job Descriptions and the Recruitment of Female Assistant Principals

Subjects: School management and organization

description: Nationwide school districts are facing challenges with filling administrative vacancies in public schools. Teachers are not willing to transition to administration and assume the increased responsibilities and demands placed upon school principals in today’s high-stakes educational environment. Moreover, policies fail to address the shortage of women in educational leadership or deconstruct the gender issues related to recruitment. This mixed methods study employed critical choice theory and business recruitment models to investigate how hypothetical job descriptions impacted the recruitment of women into assistant principal positions. Previous empirical research and literature from business and educational sectors provided the framework for the design of this study. Certified teachers from one rural school district in North Carolina volunteered for this investigation. All participants completed a demographic survey and a recruitment simulation to assess applicant attraction to hypothetical job descriptions based on the attributes of school management or collaborative leadership. Additionally, female teacher leaders participated in ethnographic interviews to further explore their perception of assistant principal job descriptions. The major findings in this study indicated a teacher’s age and years of teaching experience were the most significant factors that influenced a teacher’s willingness to pursue an assistant principal position. Further, the research denoted gender and the job attribute of collaborative leadership impacted the attraction to an assistant principal job description. These findings revealed potential implications for future research in regards to hiring practices, recruitment policies, and future studies related to the assistant principal position. With a limited resource of qualified personnel, school systems are encouraged to examine their guidelines and procedures for recruiting and hiring personnel and to develop and implement job descriptions that are appealing to applicants.

description: Tourism climatology studies relationships among people, business, weather, and climate within the tourism industry. This research tests these interfaces in the southeast United States at the North Carolina Zoo and Zoo Atlanta. Historical weather data are paired with zoo attendance. Weather variables include observed variables of temperature, humidity, cloud cover, and wind speed; derived variables of wind chill and heat index; and biometeorological index variables of Physiologically Equivalent Temperature (PET), Standard Effective Temperature (SET), and Predicted Mean Vote (PMV). Three analyses are used: correlation, multiple regression, and probabilistic. Correlation analysis compares direct relationships between weather variables and attendance. Multiple regression analysis combines standard variables in predictive models. Probabilistic analysis studies seasonal scale climate-attendance relationships. Results indicate weather influences on zoo attendances change by season, social influences, and geography of the zoo. Complex composite weather variables improve attendance predictability as they provide better assessments of how humans sense outdoor environments.
Dynamics of condensate formation in stochastic transport with pair-factorized steady states: Nucleation and coarsening time scales

description: Driven diffusive systems such as the zero-range process (ZRP) and the pair-factorized steady states (PFSS) stochastic transport process are versatile tools that lend themselves to the study of transport phenomena on a generic level. While their mathematical structure is simple enough to allow significant analytical treatment, they offer a variety of interesting phenomena. With appropriate dynamics, the ZRP and PFSS models feature a condensation transition where for a supercritical density the translational symmetry breaks spontaneously and excess particles form a single-site or spatially extended condensate, respectively. In this paper we numerically study the typical time scales of the two stages of this condensation process: Nucleation and coarsening. Nucleation is the first stage of condensation where the bulk system relaxes to its stationary distribution and droplet nuclei form in the system. These droplets then gradually grow or evaporate in the coarsening regime to finally coalesce in a single condensate when the system finally relaxes to the stationary state. We use the ZRP condensation model to discuss the choice of the estimation method for the nucleation time scale and present scaling exponents for the ZRP and PFSS condensation models with respect to the choice of the typical droplet mass. We then proceed to present scaling exponents in the coarsening regime of the ZRP for partial-asymmetric dynamics and the PFSS model for symmetric and asymmetric dynamics.

description: This study will investigate the varying behaviors associated with efforts by teachers to plan, prepare and implement instructional practices for their students. Efforts will be made to distinguish differences in these behaviors in an effort to identify those behaviors that are associated with teachers that have produced high value-added gains scores among the students they teach. This study will explore possible measures that might begin to provide such data for improving teacher effectiveness. Findings from this study provide useful information in exploring the complexities involved in observing effective teaching that promotes student learning. There are factors that, in this study that are proven predictors of teacher effect scores. There are other factors, of this study that have proven to make a difference when experience has been considered. There are, no doubt, other factors that are yet to be explored that may contribute as much or more to the equation of best instructional behaviors proven to increase student progress. It is the belief of the researcher that a perfect observational instrument has not been found. Much more work is necessary before we put children in jeopardy of being recipients of poorly constructed instructional strategies that are not grounded in a series of sound and rigorous scientific inquiries. Without a connection between teaching and learning, the act of teaching becomes negligible. We must continue to ask ourselves if the observational instruments we use explain practices found to promote student learning. It is imperative that educational researchers continue to search and question tools being used to determine instructional practices that are most effective at promoting student learning.

description: We compute the area term contribution to black holes' entanglement entropy (using the conical technique) for a class of local or weakly non-local super-renormalizable gravitational theories coupled to matter. For the first time, we explicitly prove that all the beta functions in the proposed theory, except for the cosmological constant, are identically zero in cut-off regularization scheme and not only in dimensional regularization scheme. In particular, we show that there is no divergence quadratic in cut-off and hence there is no contribution to the beta function of the Newton constant. As a consequence of this result, we argue that in these theories of gravity conical entropy is a sensible definition of physical entropy, in particular, it is positive-definite and gauge-independent. On top of this the conical entropy, being expressed only in terms of the classical Newton constant, turns out to be finite and naturally coincides with Bekenstein-Hawking entropy. Finally, we propose a theory in which the renormalization of the Newton constant is entirely due to the Standard Model matter, arguing that such a contribution does not give the usual interpretational problems of conical entropy discussed in the literature.

A Study of Family Risk Contexts and Child Conduct Problems Among Rural, Low-Income Families

description: This dissertation research is comprised of three studies using data from a larger study, the Family Life Project, aimed at examining the role of family functioning in the development of conduct problems in young children within high-risk contexts. Specifically, study 1, using propensity-matched controls, explores long-term adjustment of women in terms of individual functioning, parenting behavior, and relationship quality as a function of childhood sexual trauma status. Study 2 focuses attention on the pathways by which a mother's childhood sexual trauma may exert influence on her parenting behavior and thereby influence the behavioral development of her children, including her depressive symptomatology, parenting behavior, and alcohol and substance use using the same propensity matched sample as in study 1. Using a subsample of resident fathers from the larger Family Life Project, the focus of study 3 was on mothers' adaptive parenting strategies of maternal gatekeeping behaviors in the prediction of conduct problems in her children in the context of a home environment with an alcohol-and substance-using father and intimate partner violence. Data for these analyses were obtained from mother reports and coding from observational protocols from the Family Life Project. The use of propensity-matched controls to create a control group matched on family of origin variables, study 1 provides evidence that when women with childhood sexual trauma are compared with the matched comparison women, females who experienced childhood sexual trauma show poor functioning, across many domains including interpersonal functioning, relationship quality and parenting. Study 2 provides evidence to support the notion that mothers' childhood sexual trauma is related to child conduct problems in her children. The findings from study 2 reveal that maternal childhood sexual trauma, her depressive symptoms, intimate partner violence, and maternal parenting are closely linked to child conduct problems. The findings from study 3 suggest that intimate partner violence and fathers' alcohol and substance use are related to his harsh intrusive parenting, which in turn is related to child conduct problems. There was evidence that maternal gatekeeping moderates the association between fathers' harsh intrusive parenting and child conduct problems, such that mothers encouragement of fathers high in harsh intrusive parenting to spend greater, as compared to less time with their children, was related to higher levels of conduct problems. In sum, this research highlights the importance of examining multiple family contexts to understanding conduct problems in young children.

description: Die Zahl der Scheidungen nimmt sowie in Deutschland als auch in Korea zu. Das heißt, es wird für mehr Menschen wichtig, mit welchen finanziellen und anderen Folgen ein geschiedenes Paar zu rechnen hat. Sehr oft ist die Ehefrau in einer sozial schlechteren Position, weil sie wenige Beschäftigungsmöglichkeiten auf dem Arbeitsmarkt hat als der Mann und weil sie sich um die Kinder kümmert. Die Gesetze hinsiehtlich der Scheidungsfolgen wurden in Deutschland genauer ausgearbeitet als in Korea. In Korea sind sie häufiger Ermessensentscheidungen des Gerichts als in Deutschland. Drei wichtige finanzielle Möglichkeiten im deutschen Recht sind Zugewinnausgleich, der nacheheliche Unterhaltsanspruch und der Versorgungsausgleich. Zwei wichtige finanziellen Möglichkeiten im koreanischen Recht sind der Vermögensteilungsanspruch und der Schmerzensgeldanspruch. Das Rechtssystem von beiden Länder sind unterschiedlich. Ein Unterschied zwischen Deutschland und Korea ist, daß der Ausgleich der Rentenversorgung in Deutschland eine wichtige Scheidungsfolge ist und in Korea wenig entwickelt ist. Die unterschiedlichen Rechtssysteme werden verglichen.
description: The number of divorces increases both in Germany and in Korea. That means that it is important for a larger number of people to know what financial and other consequences a divorced couple have to face. Very often the wife is in a socially worse situation, because she has fewer job opportunities and she cares for the children. The law of consequences after a divorce is more exactly worked out in Germany than in Korea. In Korea it is more often a matter of opinion of the court than in Germany. Three important financial possibilities in Germany are equalization of the surplus, maintenance after divorce and equalization of the pension. Two important financial possibilities in Korea are claim of propertyshares and claim of damages for pain and suffering. Both systems of law are different. A difference between Germany and Korea is that in Germany the equalization of the pension ist very important and not worked out in Korea. I compare both the German and Korean law system.
This miserable kingdom: Indian and European alliances in the Central Plains, 1692-1730

description: In the early eighteenth century, many Indian and European powers sought to establish control of the Central Plains. To do so, these powers struck alliances with other contending powers to varying degrees of success. Though the Plains Apaches saw benefits in a commercial alliance with the French to the northeast, and the Spanish initially tried for complete imperial dominance of the region, both groups ultimately needed an alliance with each other to check the growing rival alliances between the Comanches and the Utes from the Great Basin and the French and the Pawnees in the Eastern Plains. The 1720 Villasur Expedition was the culmination of this Plains Apache-Spanish alliance and resulted in immediate military defeat and long-term prevention of either group's expansion into the Central Plains.
