description: Our lack of imagination and involvement with our most neglected and abused spaces represents one of the most serious crises of contemporary living. These overlooked places — from large swaths of toxic desert wastelands to densely populated informal settlements that have literally cemented over entire mountainsides — whose people suffer from intense socio-economic marginalization and environmental degradation, are perceived to hold little value. However, through an exploration of cultural practices, this research demonstrates opportunities to envisage how these kinds of spaces can be seen as platforms for constructive process and creative resilience. Explicitly, it looks at how environmentally-engaged artistic structures can open up physical and conceptual junctures that connect critical political thought to DIY action in regions that are characterized as low income areas, by weak state capacity, or where citizens are vulnerable to a range of distresses that include limited access to public utilities, natural resources, social services, education, information technology, economic stability, and public safety. The first body of research presented in this thesis maps land degradation and reclamation efforts in the expansive desert tribal lands of the SouthwesternUnited States. The second is an urban remediation project located inside someof the largest and most densely populated favelas (slums) in all of Brazil. In bothcases, the extremities of environmental degradation collide with cultural activismin attempts to reclaim space for more ecologically and socially responsible landuse. Both of these projects ask: what happens when the rules and policyboundaries of the socio-political complex are confronted through culturalaction; how does this connect to the material production of knowledge; andfinally, how does this open up potential to redress systems of control?

description: In sub-Saharan Africa, the management of buffer zones around protected areas does not often take into serious account the needs of resource exploitation by the local populations or the conservation needs of these areas. We described the ecological characteristics and management issues affecting the buffer zone around the Fazao-Malfakassa National Park; a 192,000-ha protected area in central-western Togo of utmost conservation importance within the Dahomey Gap region. Within the buffer zone (10 km radius, 334,800 ha), we focussed on four high conservation value areas totalling 65,594 ha (20% of the total buffer zone area). Using 2015 sentinel-2 images we analyzed land cover patterns and described existing ecological zones. We complemented these with field surveys and interviews with 300 people living in 22 villages within the buffer zone to describe the conditions affecting the resident human population. Although over 60% of the total buffer zone area is degraded, we identified four areas of high conservation value (total area = 65,594 ha). Interviewees recognized that slash-and-burn was the most common form of land use, followed by agroforestry practices. Agriculture, charcoal, and firewood production were the main drivers affecting habitats, and land conflicts were recurrent due to the rise in human population. The decline in agriculture, reported by interviewees in some sectors, was attributable to ravages of crops by elephants. Three independent diversity indices showed that, in preserved zones, a greater diversity of animals (with similar utilization frequencies) were hunted than in degraded sites (where grasscutters were the dominant hunted species). There were also significant differences between degraded and preserved zones in terms of plants used for charcoal production and for non-timber forest products. We advocate the development of community-controlled hunting areas to enhance the conservation value of the four well-preserved zones. Instead, promoting sustainable agricultural production systems in the degraded areas can help to further stabilize the agricultural front and reduce land pressure on the park.

description: This collection of papers on phrasal compounding is part of a bigger project whose aims are twofold: First, it seeks to broaden the typological perspective by providing data for as many different languages as possible to gain a better understanding of the phenomenon itself. Second, based on these data which clearly show interaction between syntax and morphology it aims to discuss theoretical models which deal with this kind of interaction in different ways. Models like Generative Grammar assume components of grammar and a clear-cut distinction between the lexicon (often including morphology) and grammar. Other models, like construction grammar, do not assume such components and are rather based on a lexicon including constructs. A comparison of these models on the basis of this phenomenon on the morphology- syntax interface makes it possible to assess their descriptive and explanatory power.

description: We have studied magnetic and transport properties on different manganese oxide based compounds exhibiting phase separation: polycrystalline La5/8-yPryCa3/8MnO3 (y=0.3) and La1/2Ca1/2Mn1-zFezO3 (z = 0.05), and single crystals of La5/8-yPryCa3/8MnO3 (y=0.35). Time dependent effects indicate that the fractions of the coexisting phases are dynamically changing in a definite temperature range. We found that in this range the ferromagnetic fraction f can be easily tuned by application of low magnetic fields (< 1 T). The effect is persistent after the field is turned off, thus the field remains imprinted in the actual value of f and can be recovered through transport measurements. This effect is due both to the existence of a true phase separated equilibrium state with definite equilibrium fraction f0, and to the slow growth dynamics. The fact that the same global features were found on different compounds and in polycrystalline and single crystalline samples, suggests that the effect is a general feature of some phase separated media.

description: Gauge theory correlators are potentially more singular in the infrared than those in non-gauge theories. We determine the implications that these singularities have on the spectrum of the theory, proving that the appearance of generalised poles implies the existence of on-shell states with fixed mass, but zero norm. For quantum chromodynamics these poles have direct relevance for the confinement of coloured states. Using lattice data for the Landau gauge gluon propagator we subsequently test for the presence of these poles, establishing that the data is indeed consistent with such a component.

description: The spectral hardenings of cosmic ray nuclei above $\sim 200$ GV followed by softenings around 10 TV, the knee of the all-particle spectrum around PeV energies, as well as the pattern change of the amplitude and phase of the large-scale anisotropies around 100 TeV indicate the complexities of the origin and transportation of Galactic cosmic rays. It has been shown that nearby source(s) are most likely to be the cause of such spectral features of both the spectra and the anisotropies. In this work, we study the anisotropy features of different mass composition (or mass groups) of cosmic rays in this nearby source model. We show that even if the spectral features from the nearby source component is less distinctive compared with the background component from e.g., the population of distant sources, the anisotropy features are more remarkable to be identified. Measurements of the anisotropies of each mass composition (group) of cosmic rays by the space experiments such as DAMPE and HERD and the ground-based experiments such as LHAASO in the near future are expected to be able to critically test this scenario.

description: The Hierarchical Factor Segmentation (HFS) method is a non-parametric statistical method for detection of the phase of a biological rhythm shown in an actogram. The detection accuracy of this method was measured on actograms showing only circadian rhythms with a constant ratio of signal to noise (S/N). In the present study, we generated 84 types of artificial actograms including circadian or circatidal rhythms by using three parameters: α/ρ, S/N and period length τ, and evaluated the effectiveness of our devised adaptation of the HFS method, the cycle-by-cycle adaptation. The results showed the effectiveness of the cycle-by-cycle adaptation was high even though S/N or τ was fluctuating through a whole actogram. These suggested that the cycle-by-cycle adaptation could be effectively applied to various kinds of rhythmic activity data. The C++ source code of the cycle-by-cycle adaptation is available on the website at https://github.com/KazukiSakura/cHFS.git.

description: Quantum Lie algebras are generalizations of Lie algebras which have the quantum parameter h built into their structure. They have been defined concretely as certain submodules of the quantized enveloping algebras. On them the quantum Lie bracket is given by the quantum adjoint action. Here we define for any finite-dimensional simple complex Lie algebra g an abstract quantum Lie algebra g_h independent of any concrete realization. Its h-dependent structure constants are given in terms of inverse quantum Clebsch-Gordan coefficients. We then show that all concrete quantum Lie algebras are isomorphic to an abstract quantum Lie algebra g_h. In this way we prove two important properties of quantum Lie algebras: 1) all quantum Lie algebras associated to the same g are isomorphic, 2) the quantum Lie bracket of any quantum Lie algebra is $q$-antisymmetric. We also describe a construction of quantum Lie algebras which establishes their existence.

Glycosylation and Sialylation During Wound Healing

description: Chronic wounds significantly increase morbidity and mortality and are a consequence of disease including diabetes. Previous studies have demonstrated that glycosylation, a post- translational protein modification whereby carbohydrates are added to proteins, is altered during corneal wound healing and in diabetes. However, no studies have examined whether differential glycosylation occurs during wound healing between different tissue types, in diabetic skin wound healing, and/ or among tissues with different healing potentials. Since the skin exhibits impaired healing when compared to the oral mucosa and diabetic skin is impaired in relation to non-diabetic skin, we hypothesize that glycosylation related gene expression is altered among tissues with differential healing potentials. This study examines the differential regulation of glycosylation related genes and protein sialylation between uninjured tissue and wounds of the skin and oral mucosa using microarray analysis of glycosylation related genes and lectin blot analysis of protein sialic acid carbohydrates. Additionally, differential regulation of glycosylation related genes and glycans from diabetic and non- diabetic skin and wounds were examined via high throughput qualitative polymerase chain reactions and semiquantitative glycomics analysis. Overall, this study demonstrates that 3 glycosylation related genes related to mucins and glycogenolysis respectively are downregulated, while 18 genes associated with neutrophil degranulation, sulfation, and polysialylation among others are upregulated in tissues with impaired healing. Furthermore, time dependent increases in protein sialic acids and polysialic acids and were observed in the skin when compared to the oral mucosa while diabetic skin exhibited increases in N-linked glycan sialic acids and fucosylated, sialosyl-poly-N- acetyllactosamines when compared to non- diabetic skin. Interestingly, increased sialic acid carbohydrates have been observed in other models of acute inflammation and both polysialic acid and fucosylated, sialosyl-poly-N- acetyllactosamine carbohydrate determinant are involved in selectin- selectin ligand mediated inflammatory responses. In conclusion, protein glycosylation is differentially regulated in a tissue and disease specific manner that is associated with the inflammatory response during wound healing. Furthermore, this altered glycosylation likely contributes to the decreased healing potential observed in the skin when compared to the oral mucosa and in diabetic skin when compared to non- diabetic skin respectively, however, further validation is required.

description: In 2013, the U.S. Department of Education published revised guidelines for emergency response planning for colleges and universities in the United States. These guidelines reflect the collective work of numerous government intelligence, law enforcement, and preparedness agencies that have taken into account the past successes and failures of schools in response to natural disasters and man-made disasters such as cyber hacking and targeted violent incidents on campuses. With a collective enrollment of over 20 million students annually and valuable physical resources such as libraries, stadiums, and medical centers at institutions of higher education (IHE), an effort to identify the current safety personnel, practices, and services was conducted.
      The purpose of this research was to identify areas of IHE compliance with the government guidelines and to identify differences, if any, by school enrollment size and region of the country. A cross-sectional design was used to describe compliance with the government guidelines and examine the differences based on a random sample drawn from all accredited 4- year public colleges and universities (n=708) in the United States.
      A sample of 17% of all eligible institutions was selected (n=120), and a 70.8% response rate was obtained (n=85). Directors of public safety were interviewed by telephone and reported information regarding their school’s availability of mental health counseling, crime prevention programs, emergency communications plans, emergency operations plans, and personnel training.
      The major findings of this study revealed that only 64 (75%) schools offered disaster response presentations to new students and staff, while 9 (11%) reported that their written emergency operations plans were not available to their communities, and that only 53 (62.4%) offered presentations regarding cyber-security and safeguarding online information. This study also revealed that 40 (47%) of the respondents either did not have or did not know if their school had an emergency operations plan for dealing with database theft, and 55 (64.7%) either did not have or did not know if there was a plan in place to safeguard the private contact information used in their emergency communications systems. With an estimated 300,000+ college students annually studying abroad, only 44 (51.3%) respondents reported offering travel safety presentations to their communities. Few differences were identified based on enrollment or regional location. The implications are discussed within the context of increasing national trends of gun violence, armed civilians and officers on campuses, cyber hacking, and increased participation by students and researchers traveling abroad.

description: We consider the problem of embedding a symmetric configuration with block size 3 in an orientable surface in such a way that the blocks of the configuration form triangular faces and there is only one extra large face. We develop a sufficient condition for such an embedding to exist given any orientation of the configuration, and show that this condition is satisfied for all configurations on up to 19 points. We also show that there exists a configuration on 21 points which is not embeddable in any orientation. As a by-product, we give a revised table of numbers of configurations, correcting the published figure for 19 points. We give a number of open questions about embeddability of configurations on larger numbers of points.

description: EMPIS (COPTOPHLEBIA) HYALEA -GROUP
 References: Daugeron (2002); Daugeron & Grootaert (2003a, b).
 Monophyly: In previous papers (Daugeron, 2002; Daugeron & Grootaert, 2003a, b) the monophyly of the E. (C.) hyalea -group has been established on the basis of two characters: labella with an unsclerotized zone in the middle [character 2 (1)], and epandrial lamellae linked dorsally by a broad sclerite [26 (2)]. At present we can add a third autapomorphy: epandrium with pair of long dorsal projections [27 (2)], even if this character has reduced within the group into two small protuberances [27 (1)] or modified into a single median protuberance [27 (3)].
 Description: MALE: HEAD Ocellar triangle prominent with pair of distinct bristles; holoptic, upper ommatidia enlarged; proboscis at least as long as head, strongly sclerotized, with distinct unsclerotized zone in middle of labella. THORAX. Scutum with at least the following strong, long bristles: 1 basal postpronotal, 1 pre- and 2 postsutural supraalars, 3 notopleurals, 1 postalar, 2 apical scutellars; acrostichals absent in prescutellar depression, laterotergite with fan of strong, long bristles. LEGS. Fore tibia often deformed, more or less S-shaped or narrowed at base [E. (C.) hyalea and E. (C.) jacobsoni clades]; mid and hind legs with strong, long bristles. WING with Sc, M1 generally abbreviated, M2 complete, cell dm truncate, radial fork (R4 + 5) at right angle, anal lobe well developed. HYPOPYSIUM. Cercus with characteristic concave shape in dorsal view; epandrium with 2 long, dorsal projections or at least 2 small dorsal protuberances, unpaired with lateral lamellae linked dorsally by broad sclerite (epandrial lamellae remain feebly separated dorsally in E. (C.) nahaeoensis clade), always with strong, long bristles; hypandrium rather short, pointed apically, reduced more or less membranous in E. (C.) aspina and E. (C.) nahaeoensis clades; phallus generally quite long, slender, sometimes entirely thick.
FEMALE: Similar to male except for the following characters: entire chaetotaxy generally shorter. Dichoptic. Legs often with pennation, fore tibia unmodified. Abdomen pointed at tip with cercus longer than wide bearing some short bristly hairs.
 According to the phylogenetic analysis, the E. (C.) hyalea -group can be divided in six welldefined clades, namely E. (C.) acris, E. (C.) aspina, E. (C.) atratata, E. (C.) hyalea, E. (C.) jacobsoni and E. (C.) nahaeoensis, keyed below.

description: This dissertation examines the emergence of the 1978 Camp David Accords and the consequences for Israel, the Palestinians, and the wider Middle East. Utilizing archival sources and oral history interviews from across Israel, Palestine, Lebanon, the United States, and the United Kingdom, Camp David’s Shadow recasts the early history of the peace process. It explains how a comprehensive settlement to the Arab-Israeli conflict with provisions for a resolution of the Palestinian question gave way to the facilitation of bilateral peace between Egypt and Israel. As recently declassified sources reveal, the completion of the Camp David Accords—via intensive American efforts— actually enabled Israeli expansion across the Green Line, undermining the possibility of Palestinian sovereignty in the occupied territories. By examining how both the concept and diplomatic practice of autonomy were utilized to address the Palestinian question, and the implications of the subsequent Israeli and U.S. military intervention in Lebanon, the dissertation explains how and why the Camp David process and its aftermath adversely shaped the prospects of a negotiated settlement between Israelis and Palestinians in the 1990s. In linking the developments of the late 1970s and 1980s with the Madrid Conference and Oslo Accords in the decade that followed, the dissertation charts the role played by American, Middle Eastern, international, and domestic actors in curtailing the possibility of Palestinian self-determination.

description: Here we present the analysis of multi-epoch secondary eclipse observations of HD 189733b and HD 209458b as a probe of temporal variability in the planetary climate using both Spitzer channels 1 and 2 (3.6 and 4.5 um). Constraining temporal variability will inform models and identify physical processes occurring at either length scales too small to directly observe or at pressure levels that are inaccessible to transit observations. We do not detect statistically significant variability and are able to place useful upper limits on the IR variability amplitudes in these atmospheres. There are very few planets with multi-epoch observations at the required precision to probe variability in dayside emission. The observations considered in this study span several years, providing insight into temporal variability at multiple timescales. In the case of HD 189733b, the best fit eclipse depths for the channel 2 observations exhibit a scatter of 102 ppm about a median depth of 1827 ppm and in channel 1 exhibit a scatter of 88 ppm about a median depth of 1481 ppm. For HD 209458b, the best fit eclipse depths for the channel 2 observations exhibit a scatter of 22 ppm about a median depth of 1406 ppm and in channel 1 exhibit a scatter of 131 ppm about a median depth of 1092 ppm. The precision and scatter in these observations allow us to constrain variability to less than (5.6% and 6.0%) and (12% and 1.6%) for channels (1,2) of HD 189733b and HD 209458b respectively. There is a difference in the best fit eclipse timing compared to the predicted time consistent with an offset hotspot as predicted by GCMs and confirmed in previous phase curve observations.

description: The dynamics of wave packets in a relativistic Dirac oscillator is compared to that of the Jaynes-Cummings model. The strong spin-orbit coupling of the Dirac oscillator produces the entanglement of the spin with the orbital motion similar to what is observed in the model of quantum optics. The collapses and revivals of the spin which result extend to a relativistic theory our previous findings on nonrelativistic oscillator where they were known under the name of `spin-orbit pendulum'. There are important relativistic effects (lack of periodicity, zitterbewegung, negative energy states). Many of them disappear after a Foldy-Wouthuysen transformation.

description: Recent advances in deep learning have markedly improved the quality of visual-attention modelling. In this work we apply these advances to video compression. We propose a compression method that uses a saliency model to adaptively compress frame areas in accordance with their predicted saliency. We selected three state-of-the-art saliency models, adapted them for video compression and analyzed their results. The analysis includes objective evaluation of the models as well as objective and subjective evaluation of the compressed videos. Our method, which is based on the x264 video codec, can produce videos with the same visual quality as regular x264, but it reduces the bitrate by 25% according to the objective evaluation and by 17% according to the subjective one. Also, both the subjective and objective evaluations demonstrate that saliency models can compete with gaze maps for a single observer. Our method can extend to most video bitstream formats and can improve video compression quality without requiring a switch to a new video encoding standard.
Roy Haynes: the early years

description: In four parts, this thesis covers the early years of the life, development, and career of Roy Haynes beginning with his ancestry and family history in Boston, to the early 1950's in New York, by which time he had become an established fixture on the scene of New York’s new evolution of African American music called bebop. The purpose of this study is to magnify the genesis of one of America’s treasured artists – taking a glimpse into the dawning of his influences and musical exposure, and later highlighting his gift in expressive versatility which carried him throughout his career, displaying the gradual making of an internationally renowned artist.Part one is comprised of four chapters, and includes an introduction and biographical information. Chapter one covers his genealogy, taking a step back to identify the sources of his African and Caribbean roots that help to inform who he is personally and musically.Chapter two sheds light upon his social and familial development in the historical context around and between World War I and The Great Depression. It touches upon the social, cultural, and economic existence of the immigrants who found themselves in and around the communities of Lower Roxbury. This section shows when and how Haynes’s talent emerged, and how through his gift he was able to build a sound reputation as a solid musician around New England. From that reputation, which traveled all the way to New York, chapter three continues with Haynes’s professional career in Boston, then leaps to New York City via a one-way train ticket to join the famed Luis Russell Orchestra. In chapter four, the author explains plans for additional research, and the continued synthesis and distillation thereof toward the eventual publication of biographical literature for both adults and children.Continuing with part two of this work, chapter five includes musical analyses highlighting Haynes’s contributions on three particular recordings between 1945 and 1949. In part three, chapters six through fourteen feature interview transcripts from nine individuals who provide an overview of expert insight spanning several generations on a variety of cultural, musical, and stylistic influences and contributions of Haynes’s artistry.Finally, in part four, there are several appendices which represent visual images on topics approached throughout, and in support of the narrative.

description: Blockchain is a distributed ledger, which is protected against malicious modifications by means of cryptographic tools, e.g. digital signatures and hash functions. One of the most prominent applications of blockchains is cryptocurrencies, such as Bitcoin. In this work, we consider a particular attack on wallets for collecting assets in a cryptocurrency network based on brute-force search attacks. Using Bitcoin as an example, we demonstrate that if the attack is implemented successfully, a legitimate user is able to prove that fact of this attack with a high probability. We also consider two options for modification of existing cryptocurrency protocols for dealing with this type of attacks. First, we discuss a modification that requires introducing changes in the Bitcoin protocol and allows diminishing the motivation to attack wallets. Second, an alternative option is the construction of special smart-contracts, which reward the users for providing evidence of the brute-force attack. The execution of this smart-contract can work as an automatic alarm that the employed cryptographic mechanisms, and (particularly) hash functions, have an evident vulnerability.

description: One trend in the recent healthcare transformations is people are encouraged to monitor and manage their health based on their daily diets and physical activity habits. However, much attention of the use of operational research and analytical models in healthcare has been paid to the systematic level such as country or regional policy making or organisational issues. This paper proposes a model concerned with healthcare analytics at the individual level, which can predict human physical activity status from sequential lifelogging data collected from wearable sensors. The model has a two-stage hybrid structure (in short, MOGP-HMM) -- a multi-objective genetic programming (MOGP) algorithm in the first stage to reduce the dimensions of lifelogging data and a hidden Markov model (HMM) in the second stage for activity status prediction over time. It can be used as a decision support tool to provide real-time monitoring, statistical analysis and personalized advice to individuals, encouraging positive attitudes towards healthy lifestyles. We validate the model with the real data collected from a group of participants in the UK, and compare it with other popular two-stage hybrid models. Our experimental results show that the MOGP-HMM can achieve comparable performance. To the best of our knowledge, this is the very first study that uses the MOGP in the hybrid two-stage structure for individuals' activity status prediction. It fits seamlessly with the current trend in the UK healthcare transformation of patient empowerment as well as contributing to a strategic development for more efficient and cost-effective provision of healthcare.

description: Quantum theory is formulated as the uniquely consistent way to manipulate probability amplitudes. The crucial ingredient is a consistency constraint: if the amplitude of a quantum process can be computed in two different ways, the two answers must agree. The constraint is expressed in the form of functional equations the solution of which leads to the usual sum and product rules for amplitudes. An immediate consequence is that the Schrodinger equation must be linear: non-linear variants of quantum mechanics violate the requirement of consistency. PACS: 03.65.Bz, 03.65.Ca.

description: Reaction systems are discrete dynamical systems inspired by bio-chemical processes, whose dynamical behaviour is expressed by set-theoretic operations on finite sets. Reaction systems thus provide a description of bio-chemical phenomena that complements the more traditional approaches, for instance those based on differential equations. A comprehensive list of decision problems about the dynamical behavior of reaction systems (such as cycles and fixed/periodic points, attractors, and reachability) is provided along with the corresponding computational complexity, which ranges from tractable problems to PSPACE-complete problems.

description: Die wissenschaftliche Haltung gegenüber der Welt gilt als vorbildlich für die moderne Zivilisation. Oft wird von der modernen als einer wissenschaftlichen Zivilisation gesprochen. Wozu dann Versuche zur Zivilisierung wissenschaftlichen Wissens? Weil beispielsweise die medizinischen Menschenversuche im Nationalsozialismus oder die militärische Nutzung der Kernspaltung für ein Bild der modernen Wissenschaften als Werkzeuge des »Zusammenbruchs der Zivilisation« stehen. Manche Sozialwissenschaftler sagen sogar, eben der Zusammenbruch sei die Zivilisation. – Ein zutiefst gespaltenes Bild! Solche gespaltenen und spaltenden Fragestellungen unterlaufend setzt dieses Buch in Mikrostudien und theoretischen Überblicken anders an: Es geht nicht mehr um die wissenschaftliche Haltung gegenüber der Welt, sondern um die wissenschaftliche Haltung in der Welt. Zivilisationsprozesse gehen durch Menschen hindurch, sie finden nicht nur zwischen, sondern auch in Menschen statt. So auch Entzivilisierungsprozesse. Beide – Zivilisationsprozesse und Entzivilisierungsprozesse – sind früh an Veränderungen des Sprechens ablesbar. Das Denken von Zivilisationsprozessen erfordert Zivilisationsprozesse des Denkens. Dieser Zusammenhang ist nirgends besser sichtbar zu machen als an Reichweite und Grenzen der zivilisationstheoretischen und der wissenssoziologischen Arbeit von Norbert Elias. Elias selbst hat den Zusammenhang zwischen seiner Zivilisationstheorie und seiner Wissenssoziologie nicht ausgearbeitet. Waldhoffs Arbeit an der Wissenssoziologie als Zivilisationstheorie führt zwei bisher unverbundene Wissensströme zusammen. Ausgangspunkt ist das Elias’sche Konzept von Engagement und Distanzierung. In diesem Modell geht es um menschliche Phantasie, die gesellschaftlichen Standards ihrer Kontrollen und die sehr unterschiedlich entwickelte Fähigkeit der Steuerung naturaler im Vergleich zu sozialen Beziehungen. Warum, fragt Elias, ist immer mehr menschlichen Gesellschaften mit dem historischen Durchbruch zu den Naturwissenschaften ein zunehmend klarer Blick auf natürliche Zusammenhänge geglückt, während ihr Blick auf gesellschaftliche Zusammenhänge noch immer von wenig kontrollierten Phantasien verhangen ist?

description: EMPIS (COPTOPHLEBIA) ATRATATA CLADE
 Monophyly: The monophyly of this clade is supported by two characters: epandrium with a dorsal double brush of spine-like bristles [character 30(1)], and epandrium with at least 1 very strong, long bristle at tip [32 (1)].
 Distribution (Fig. 16): This group of three species is typically South-east Asian, recorded from Myanmar and Thailand.
 Remarks: Although E. (C.) velutinella Frey is not included in the phylogenetic analysis and not reviewed taxonomically, a preliminary morphological study allows inclusion of this species in the E. (C.) atratata clade as well as in the key given below. A fourth species from China (Yunnan) with 2 very strong, long bristles at the tip of the epandrium seems to also belong to this clade. It is known from 1 male and 2 females (KBIN–IRScNB) but not described here because of the poor condition of the specimens.

description: A supermanifold M is canonically associated to any pseudo Riemannian spin manifold (M_0,g_0). Extending the metric g_0 to a field g of bilinear forms g(p) on T_p M, p\in M_0, the pseudo Riemannian supergeometry of (M,g) is formulated as G-structure on M, where G is a supergroup with even part G_0\cong Spin(k,l); (k,l) the signature of (M_0,g_0). Killing vector fields on (M,g) are, by definition, infinitesimal automorphisms of this G-structure. For every spinor field s there exists a corresponding odd vector field X_s on M. Our main result is that X_s is a Killing vector field on (M,g) if and only if s is a twistor spinor. In particular, any Killing spinor s defines a Killing vector field X_s.

Can Cash Flow Expectations Explain Momentum and Reversal

description: This dissertation delves into the relation between asset returns, risks, and cash flow expectations. The first chapter uses the model-implied patterns of cash flow expectations to differentiate among the three most prominent behavioral theories explaining stock return momentum and reversal. Using analyst earnings forecasts as a proxy for cash flow expectations, I trace the dynamics of the expectation errors for winner and loser stocks in a 24-month holding period, during which returns are characterized by a momentum phase followed by a reversal phase. The large positive cross-sectional difference in expectation errors between winner and loser stocks gradually shrinks to zero over the holding period. This pattern is most consistent with the underreaction hypothesis in Hong and Stein (1999), in which cash flow expectation errors can only explain momentum, and price extrapolation is needed to explain reversal.
      The second chapter examines carry trade returns formed from the G10 currencies. Performance attributes depend on the base currency. Spread-weighting and risk-rebalancing positions over time improve performance. Hedging with options reduces profitability. Equity, bond, FX, and volatility risks cannot explain profitability. Time-varying dollar exposure produces abnormal excess returns. Dollar-neutral carry trades exhibit insignificant abnormal returns, while the dollar exposure part of the carry trade earns significant alphas and little skewness. Downside equity market betas of carry trades are not significantly different from unconditional betas. Distributions of drawdowns and maximum losses from daily data indicate the importance of autocorrelation in determining the negative skewness of longer horizon returns.
      The third chapter investigates the question of whether sovereigns pay a premium on their own borrowing as a result of (implicitly or explicitly) guaranteeing  sub-entities' debt has been explored only little. We use an event study approach with separate equations for two levels of government to test for a simultaneous increase in sovereign risk premia and decrease in sub-national risk premia--or a de facto transfer of risk from the latter to the former--on the day a sovereign bailout is announced. Using daily financial market data for Spain and its autonomous regions from January 2010 to June 2013, we find support for our risk transfer hypothesis.  We estimate that the Spanish sovereign's spread may have increased by around 70 basis points as a result of the central government's support for fiscally distressed comunidades autónomas.
