description: The flora of 88 villages in different regions of Lower Saxony is registered and described. A total of 380 spontaneaus species occurs in the village centres. The Arction, Onopordetalia and Sisymbrion species, in the literature called the "typical village species", are of low importance whereas species of meadows (Molinio-Arrhenatheretea), nitrophilaus skirts (Giechometalia) and weeds of arable land (Stellarietea) are very important for the vegetation cover of the villages. Only 10 ruderal species of the 380 species are high-frequent in all villages of all regions. These species are to be classified as settlement companions, most of them are to be found in towns too; only Lamium album is characteristic for villages. The floristical specialities of the several regions of Lower Saxony were pointed out, whereby the villages in the transition area lowland - hill country are found to be rich in species. In the opposite the village ruderal flora of Eastern Frisia, of the western border of the Harz Mountains and of the Heath is relatively poor in species. Besides the village centres old manors and their parks, new building areas, refuse pits as well as railways stations were investigated. The comparison of the village flora with the flora of 10 old towns in Lower Saxony shows a great similarity, however there are also some differentiating species. The village flora of Lower Saxony is compared also to the village flora of other European regions by the aid of three different methodical approaches. Informations on the village flora of Thiérache, Britanny, Liguria and Andalusia are published for the first time.

description: By using a class of `anyon like' representations of permutation algebra, which pick up nontrivial phase factors while interchanging the spins of two lattice sites, we construct some integrable variants of $SU(M)$ Haldane-Shastry (HS) spin chain. Lax pairs and conserved quantities for these spin chains are also found and it is established that these models exhibit multi-parameter deformed or nonstandard variants of $Y(gl_M)$ Yangian symmetry. Moreover, by projecting the eigenstates of Dunkl operators in a suitable way, we derive a class of exact eigenfunctions for such HS like spin chain and subsequently conjecture that these exact eigenfunctions would lead to the highest weight states associated with a multi-parameter deformed or nonstandard variant of $Y(gl_M)$ Yangian algebra. By using this conjecture, and acting descendent operator on the highest weight states associated with a nonstandard $Y(gl_2)$ Yangian algebra, we are able to find out the complete set of eigenvalues and eigenfunctions for the related HS like spin-${1\over 2}$ chain. It turns out that some additional energy levels, which are forbidden due to a selection rule in the case of SU(2) HS model, interestingly appear in the spectrum of above mentioned HS like spin chain having nonstandard $Y(gl_2)$ Yangian symmetry.

description: Distributed phased arrays based multiple-input multiple-output (DPA-MIMO) is a newly introduced architecture that enables both spatial multiplexing and beamforming while facilitating highly reconfigurable hardware implementation in millimeter-wave (mmWave) frequency bands. With a DPA-MIMO system, we focus on channel state information (CSI) acquisition and hybrid precoding. As benefited from a coordinated and open-loop pilot beam pattern design, all the sub-arrays can perform channel sounding with less training overhead compared with the traditional orthogonal operation of each sub-array. Furthermore, two sparse channel recovery algorithms, known as joint orthogonal matching pursuit (JOMP) and joint sparse Bayesian learning with $\ell_2$ reweighting (JSBL-$\ell_2$), are proposed to exploit the hidden structured sparsity in the beam-domain channel vector. Finally, successive interference cancellation (SIC) based hybrid precoding through sub-array grouping is illustrated for the DPA-MIMO system, which decomposes the joint sub-array RF beamformer design into an interactive per-sub-array-group handle. Simulation results show that the proposed two channel estimators fully take advantage of the partial coupling characteristic of DPA-MIMO channels to perform channel recovery, and the proposed hybrid precoding algorithm is suitable for such array-of-sub-arrays architecture with satisfactory performance and low complexity.

description: Entertainment-education has been touted as a potent delivery channel for health education campaigns. Yet, there is little evidence of its causal effects. This paper aims to fill the gap in the literature by using a field experiment in India to study two questions on the efficacy of health entertainment-education. First, can health entertainment-education, particularly through films that show role models and draw on emotions, lead to lasting, positive change in health knowledge and behavior? Second, can financial incentives for ex-post health literacy boost the effectiveness of health entertainment-education? The results show that health entertainment-education successfully increased health knowledge (e.g. knowledge about cleanliness and hygiene) by 16 percent. These gains persist almost one year later, although there were no observed impacts on health behaviors. Further, financial incentives do not appear to have any effects. These insights contribute to our knowledge of what works for health education in low-income settings, so that future education campaigns can be crafted with more meaningful impact.

description: We give elementary derivations of several classical and some new summation and transformation formulae for bilateral basic hypergeometric series. For purpose of motivation, we review our previous simple proof ("A simple proof of Bailey's very-well-poised 6-psi-6 summation", Proc. Amer. Math. Soc., to appear) of Bailey's very-well-poised 6-psi-6 summation. Using a similar but different method, we now give elementary derivations of some transformations for bilateral basic hypergeometric series. In particular, these include M. Jackson's very-well-poised 8-psi-8 transformation, a very-well-poised 10-psi-10 transformation, by induction, Slater's general transformation for very-well-poised 2r-psi-2r series, and Slater's transformation for general r-psi-r series. Finally, we derive some new transformations for bilateral basic hypergeometric series of Chu-Gasper-Karlsson-Minton-type.

description: We analyse in a systematic way the (non-)compact n-dimensional Einstein Weyl spaces equipped with a cohomogeneity-one metric. With no compactness hypothesis, we prove that, as soon as the (n-1)-dimensional space is an homogeneous reductive Riemannian space with an unimodular group of left-acting isometries G 1)a non-exact Einstein-Weyl stucture may exist only if the (n-1)-dimensional homogeneous space G/H contains a non trivial subgroup H' that commutes with the isotropy subgroup H, 2) the extra isometry due to this Killing vector corresponds to the right-action of one of the generators of the algebra of the subgroup H'. We also prove that the subclass with a one-dimensional subgroup H' corresponds to n-dimensional Riemannian locally conformally Kähler metrics, the (n-2)-dimensional space G/(HxH') being an arbitrary compact symmetric Kähler coset space.

description: We initiate a study of maximal subgroups and maximal von Neumann subalgebras which have the Haagerup property. We determine maximal Haagerup subgroups inside $\mathbb{Z}^2 \rtimes SL_2(\mathbb{Z})$ and obtain several explicit instances where maximal Haagerup subgroups yield maximal Haagerup subalgebras. Our techniques are on one hand based on group-theoretic considerations, and on the other on certain results on intermediate von Neumann algebras, in particular these allowing us to deduce that all the intermediate algebras for certain inclusions arise from groups or from group actions. Some remarks and examples concerning maximal non-(T) subgroups and subalgebras are also presented, and we answer two questions of Ge regarding maximal von Neumann subalgebras.

The Culture of Green: The Role of Cultural Worldviews, Psychological Connectedness, Time Discounting, and Social Norms in Environmental Decisions

Publisher: name: Columbia University
Year: 2011
Subjects: subject: Social psychology
subject: Management
subject: Ecology
subject: FOS: Biological sciences

description: In this dissertation, I examine cultural differences in perceptions of time looking at intertemporal decisions, social norms, policy preferences, and behaviors in the environmental domain. Looking closely at the environmental domain allows for a unique opportunity to examine whether or not cultural worldviews or social norms are motivating environmental behaviors (e.g. energy conservation). It is also possible to test whether the uncertain nature of climate change and its impacts over time results in different temporal discounting rates compared to other intertemporal choice domains (e.g. financial gains or financial losses). I draw upon theories of the self to argue that culture affects intertemporal decisions. I describe research supporting culture's effect on how individuals evaluate gains and losses, or benefits and risks, over different temporal horizons. I test whether culture affects temporal orientations, such that cultures that encourage holistic thinking are more likely to view the self and environment as continuous over long time horizons, while those cultures that encourage focused thinking are less likely to see such continuity over time. I next draw on theoretical and empirical evidence from cross-cultural psychology to argue that these country differences in temporal orientations have an effect on intertemporal decisions, examining in particular decisions about environmental policy and energy conservation behaviors. In Study 1, I compare Anglo-Saxon countries with Latin-American countries to look at the role that cultural worldviews (i.e. egalitarian, individualistic, hierarchic, and fatalistic) play in influencing environmental policy preferences and pro-environmental behavioral intentions. In Study 2, I test whether different construals of the self (either independent or interdependent) have an influence, above and beyond worldview effects, on environmental decisions. Finally, in Study 3, I compare Americans and Japanese to look at the effect of psychological connectedness above and beyond its effect on discounting. I also test whether there is cross-cultural variation in expectations in the types of green behaviors (e.g. easy versus hard) to engage in. With the three studies that I summarize in the chapters that ensue, I hope to identify some of the processes by which culture influences environmental decisions.
The Currents of Restless Toil: Colonial Rule and Indian Indentured Labor in Trinidad and Fiji

Imperialism

description: The study of Indian indentured servitude in the British Empire has largely been confined to the histories of slavery or free labor. Few scholars have connected indenture to larger processes in the British Empire. This dissertation examines the global nature of Indian indenture to find how trends in colonial power were inflected in the relationship between the state and the indentured worker. This dissertation uses the colonial experience in South Asia as a basis for its global history. It contends that the history of the colonial rule of law in the subcontinent was of deep importance to the mechanisms of indenture.
      By looking at archival records from the United Kingdom, Trinidad, Fiji, and elsewhere, this dissertation finds that officials in the indenture colonies were attempting to transform indebted Indian peasants into indentured workers. This process was inflected by the experience of colonial rule elsewhere. At first, this meant the implementation of ideas tied to imperial liberalism.
      Following the challenges to British colonialism in the mid-nineteenth century, the indenture colonies mirrored a wider movement towards conservative governance. The ways in which the colonial state attempted to control and manipulate workers underwent a dramatic shift. In the indenture colony, colonial power exerted both authoritarian and paternalist tendencies. This dissertation uses the governorships of Arthur Hamilton-Gordon in Trinidad and Fiji to explore this shift.
      This dissertation makes its argument by focusing on the indenture colonies of Trinidad and Fiji. In doing so, it moves beyond the model of studying indenture that has looked at the British Empire as a whole, or otherwise in specific colonies or sub-regions. Using Trinidad and Fiji allows for a deep understanding of continuity and change. For example, Trinidad can be used to examine indenture’s beginnings, as the colony began to import Indian indentured labor in 1842, while Fiji can be used to understand late indenture. Furthermore, colonial officials, ideas of authority, capital, labor, and goods were always circulating throughout this global empire. The study of Trinidad and Fiji allows for a critical understanding of such exchanges and this dissertation uses both to explore bureaucratic offices, law, financial systems, governance, protest, medicine and health, and global agitation in Indian indenture.
       “The Currents of Restless Toil” is an in-depth study into the nature of colonial governance in the indenture colonies of Trinidad and Fiji. It explores the nuances of colonial power, providing a window into the theory and practice that shaped the restless toil of Indians across the world.

description: This paper provides a political-economic analysis of policy evaluation. We focus on Randomized Controlled Trials (RCTs) as a subset of policy evaluations and argue that they are used instrumentally by decision-makers in order to improve perceptions of reforms and help secure policy legacy. We theorize that this ’credibility premium’ is more valuable for incumbents in politically polarized societies, which we empirically examine using two methods. First, we provide a series of vignettes of prominent randomized evaluations embedded by governments in policy roll-outs and a detailed case study of the Liberian government’s decision to commission a third-party RCT evaluation of a proposed primary school privatization reform. Second, we have compiled a unique cross-country panel data set on RCTs in development policy since 1996, with which we demonstrate that RCTs are more likely to occur in polarized societies, and that the effect is amplified by the degree of political competition.

description: Large, unexpected shocks are becoming more frequent, making the design of robust social transfer programs more vital than ever. We evaluate the performance of the Food Friendly Program (FFP), the largest in-kind social transfer program in Bangladesh, before and during the nation-wide COVID-19 lockdown. Using two-rounds of nationally representative household surveys combined with administrative data, we document that high leakages and large welfare losses are related to corruption. This contrasts with the performance of the pre-lockdown FFP, when leakage was low and coverage high. We then compare the performance of the FFP with two initiatives launched following the pandemic: an in-kind and cash transfer program, respectively. These programs have markedly higher levels of leakage than the FFP. Our findings are relevant to other large shocks, such as those caused by climate change, and have important policy implications for the design and delivery of transfer programs in developing countries characterized by institutional weaknesses.

description: We consider $(3+1)$-dimensional, Dirac electrons of arbitrary mass, propagating in the presence of electric and magnetic fields which are both parallel to the $x^3$ axis. The magnetic field is constant in space and time whereas the electric field depends arbitrarily upon the light-cone time parameter $x^+ = (x^0 + x^3)/\sqrt{2}$. We present an explicit solution to the Heisenberg equations for the electron field operator in this background. The electric field results in the creation of electron-positron pairs. We compute the expectation values of the vector and axial vector currents in the presence of a state which is free vacuum at $x^+ = 0$. Both current conservation and the standard result for the axial vector anomaly are verified for the first time ever in $(3+1)$-dimensional light-cone QED. An interesting feature of our operator solution is the fact that it depends in an essential way upon operators from the characteristic at $x^- = -L$, in addition to the usual dependence upon operators at $x^+ = 0$. This dependence survives even in the limit of infinite $L$. Ignoring the $x^-$ operators leads to a progressive loss of unitarity, to the violation of current conservation, to the loss of renormalizability, and to an incorrect result for the axial vector anomaly.

The D-Day Series: Robert Capa and His Iconic Images of War

description: From the outbreak of World War II, photographers, cameramen, and journalists flooded Europe in an effort to capture images of the ongoing battles. For many Americans, one particular battle has become an icon of the European theater: the invasion of D-Day. In the early morning hours of June 6, 1944, an armada of Ally ships made the turbulent journey across the English Channel to Normandy. Operation Overlord, as D-Day was formally called, was designed to open the western front and push the Germans out of France and back east. Due to the German machine guns strategically perched on the cliffs above, thousands of men died before they even made it onto the beaches. On one section of the coast, referred to as Omaha Beach, nothing seemed to go as planned. A LIFE magazine photographer named Robert Capa “managed to bring back from Omaha Beach the most frequently reproduced film of the D-Day landings.”  His photographs are raw and expressive in their depiction of the extreme chaos of the invasion.
The Cycle of Gaseous Baryons Between the Disk and Halo

description: The gaseous halo surrounding a galaxy disk is often referred to as the circum-galactic medium (CGM). The boundary of the CGM is loosely defined as the virial radius of the galaxy. Recent observations and simulations have shown that the CGM is massive, multiphase, clumpy, and metal-enriched. The CGM plays an important role in galaxy formation and evolution – it serves as a massive baryonic reservoir, from which the disk accretes gas fuel to sustain the star-formation activities, and to which the disk deposits feedback material. This dissertation focuses on the gas distribution in the CGM of the Milky Way (MW) and the baryon cycle between the CGM and disk of our neighbor – the Triangulum Galaxy (M33).
      Observations of the MW’s CGM are unavoidably contaminated by foreground gas since we reside in the MW’s disk. Conventionally, a velocity cut at |VLSR|~100 km/s is used as a proxy for distance, with low-velocity (|VLSR|<100 km/s) gas being more nearby to the Galactic disk than high-velocity gas. Using both a MW-mass simulation and all-sky QSO observations, I show that the low-velocity gas in the MW’s CGM is as massive as their high-velocity counterpart, and that the MW most likely hosts a massive CGM reservoir as those L~L* galaxies at z~0.2.
      I further study how baryons are cycled between the disk and CGM by observing gas accretion in M33. Using HST/COS to observe seven UV-bright stars in M33’s disk, I find that there is a layer of metal-enriched inflow moving towards M33 at a rate of dM/dt=2.9 Msun/yr. The gas inflow may be related to galactic fountain process or debris falling back down due to the potential past M31-M33 interaction. This work is among the first to unambiguously reveal the existence of a disk-wide, ionized galactic inflow beyond the Milky Way. In addition, with the same set of HST/COS sightlines, I make a serendipitous discovery of an ionized very-high-velocity cloud towards M33.

We show that, unlike a commutative MOG black hole, in the coherent state picture of non-commutativity MOG black holes are thermodynamically stable. At the final stage of evaporation, a stable remnant with zero temperature and finite entropy is left in this noncommutative framework. Also, we consider Parikh-Wilczek tunneling mechanism of massive particles from non-commutative MOG black holes and demonstrate that information leaks out of non-commutative MOG black holes in the form of some non-thermal correlations.

description: Since the early 2000s, some Indian states started allowing private traders to buy directly from farmers outside the state-regulated market system. The experience of these states can shed light on the impact of market-oriented reforms and the role of public procurement. Using individual-level National Sample Survey Data on agricultural wages and a new dataset on state-level average real farm income per cultivator for 18 major Indian states between 1987–2012, this paper shows, using both a difference-in-difference and a triple difference framework, that marketing reforms alone did not contribute to higher farm incomes and agricultural wages. However, when these reforms were coupled with public procurement at the minimum support price, farm incomes and agricultural wages significantly improved. Our results suggest that market-reforms and public procurement at minimum support prices were complements which together contributed to raising rural incomes in states like Haryana, Madhya Pradesh, and Andhra Pradesh.

In this setting we describe the SOC attractor, and discuss its fractal structure. We show how the Lyapunov exponents, the Hausdorff dimensions, and the system size are related to the probability distribution of the avalanche size, via the Ledrappier-Young formula.

description: We consider four-dimensional dyonic single-center BPS black holes in the $N=2$ STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars $S, T, U$ are taken to be large, we evaluate the quantum entropy function for these BPS black holes. In this regime, the subleading corrections point to a microstate counting formula partly based on a Siegel modular form of weight two. This is supplemented by another modular object that takes into account the dependence on $Y^0$, a complex scalar field belonging to one of the four off-shell vector multiplets of the underlying supergravity theory. We also observe interesting connections to the rational Calogero model and to formal deformation of a Poisson algebra, and suggest a string web picture of our counting proposal.

description: Objective: Cervical cancer is a huge public health issue in Morocco which represents the second most frequent and fatal cancer among women. Countries that have not yet introduced the HPV vaccine could benefit greatly, but before implementation it is necessary to perform country-specific economic assessments that include current screening practices. Methods: A Markov model was developed to simulate the natural history of HPV and cervical cancer so as to calculate the long-term health benefits and costs of HPV vaccination and current screening by visual inspection with acetic acid (VIA). Starting from a previous transition probability matrix used for a model from Spain, the present model was calibrated to cervical cancer incidence from Morocco. Cost survey data was used to estimate the cost of screening and clinical procedures from the public healthcare perspective. Incremental cost-effectiveness ratios were calculated as 2018US$ per additional year of life saved (YLS) and both costs and health outcomes were discounted at 3%. Results: The expected reduction in lifetime risk of cervical cancer for current screening would be 14% at a cost of US$551/YLS compared with no intervention, assuming VIA every 3 years in women aged 30–49 at 10% coverage. HPV vaccination of pre-adolescent girls at 70% coverage would reduce the lifetime risk of cervical cancer by 62% at a cost of US$1,150/YLS, compared with no intervention. When implementing HPV vaccination in combination with current screening, vaccination would be dominated, and the combined strategy would provide a 69% reduction at a cost of US$2,843/YLS, compared with screening alone. Current screening would be dominated by vaccination when screening coverage is higher than 15%, whereas the combined strategy rapidly exceeds US$4,000/YLS. Conclusions: HPV vaccination could be highly effective and cost-effective in Morocco. Current screening would be good value for money compared with no intervention, but scaling-up screening coverage would make it inefficient compared with vaccination.
A new A_n extension of Ramanujan's 1-psi-1 summation with applications to multilateral A_n series

description: In this article, we derive some identities for multilateral basic hypergeometric series associated to the root system A_n. First, we apply Ismail's argument to an A_n q-binomial theorem of Milne and derive a new A_n generalization of Ramanujan's 1-psi-1 summation theorem. From this new A_n 1-psi-1 summation and from an A_n 1-psi-1 summation of Gustafson we deduce two lemmas for deriving simple A_n generalizations of bilateral basic hypergeometric series identities. These lemmas are closely related to the Macdonald identities for A_n. As samples for possible applications of these lemmas, we provide several A_n extensions of Bailey's 2-psi-2 transformations, and several A_n extensions of a particular 2-psi-2 summation.

The Day After Tomorrow: Waiting for the Future in Contemporary Rwanda

description: This dissertation argues that the operating temporal logic at the core of the state sanctioned models of forgiveness and reconciliation is a view of the past as apocalyptic in the future. The past as an apocalyptic imaginary hovers over the present like a ghost threatening repetition. In this political conception of the past, it is not simply a matter of chronology i.e. genocide and its aftermath. Rather, in the injunction to overcome the past through continuous remembrance, the past is made agentive in the present. This animation of the past in the present renders it continually dangerous lest it return as the future: the present must be continually mobilized, watchful and cautious so that the violent past does not return as the future. This temporal logic is reflected in the juridical demand for apologies and pardons, as mandated by the Rwandan state. The state attempts to control both ends of the equation: it demands collective catharsis on the grounds that without it Rwanda cannot overcome its past, but it simultaneously fixes in advance, and by law, the outcome of catharsis: forgiveness and reconciliation. Using fieldwork, individual and group interviews conducted in labour camps for perpetrators (Travaux d'Intérêt Général) as well as participant observation in 'unity' associations (cooperatives), this dissertation demonstrates how this model for apologies and reconciliation collapses under the weight of the internal contradiction of both demanding catharsis and controlling its result: the necessity for reconciliation. Individuals publicly perform a demonstration of affect that they circumvent and push against in their everyday experiences away from the audience. When the performances themselves fail—as they do on occasion—the language of ‘trauma’ (in the case of the victim) and ‘genocide denial’ (in the case of the perpetrators) is mobilized in order to secure the impossible demand to perform private feelings in public ceremonies wherein the meaning of such performances is juridically defined in advance. The result, I argue, are public scenes of unity, in which individuals perform a socially shared code of acting in public that they often push against away from an audience. In their lives, Rwandans constantly wrestle with this past and its traces in the everyday, sometimes in accordance to the public narrative of reconciling but also in opposition to it. There is in other words messiness on the ground, which suggests that the predominant models for thinking about post-conflict spaces along the binaries reconciliation or violence miss this complexity. I propose, the notion of an afterlife of violence as a conceptual tool. This allows us to move away from the possibility of resolvability and redemptive narratives and instead opens up the possibility of irresolvabilty: that of living with tension.

description: We estimate the community-level impact of foreign aid projects on women’s empowerment in the country with the most complete recent record of geo-coded aid project placement, Malawi. Our estimates can thus be interpreted as the average impact of aid from many different donors and diverse projects. We find that aid in general has a positive impact, in particular on an index of female agency and women’s sexual and fertility preferences. Gender-targeted aid has a further positive impact on women’s sexual and fertility preferences, and more tentatively on an index focusing on gender-based violence. However, the positive impact of gender-targeted aid disappears in patrilineal communities, and men’s attitudes towards female agency in the areas of sexuality and fertility are even negatively affected. This suggests that donors need to consider that the impact of aid on female empowerment can depend on the community context when they decide on aid project design and placement.

description: We show that an automaton group or semigroup is infinite if and only if it admits an $ω$-word (i. e. a right-infinite word) with an infinite orbit, which solves an open problem communicated to us by Ievgen V. Bondarenko. In fact, we prove a generalization of this result, which can be applied to show that finitely generated subgroups and subsemigroups as well as principal left ideals of automaton semigroups are infinite if and only if there is an $ω$ -word with an infinite orbit under their action. The proof also shows some interesting connections between the automaton semigroup and its dual. Finally, our result is interesting from an algorithmic perspective as it allows for a reformulation of the finiteness problem for automaton groups and semigroups.

description: When Our Lady Queen of Angels closed as a part of routine parish reorganization in 2007, parishioners formed a weekly protest and prayer group that met outside the church on Sunday mornings. This group has continued for over eight years now. Through participant-observation and interviews, this study looks at the causes of the longevity of the protest group, as well as their alienation from the institutional Catholic church. Thanks to networks formed through in-church participation, parishioners were able to find and activate a protest group. The group's continued existence owes itself to the transition of the group's goals from protest to praise. The implications of its longevity represents an institutional failure on the part of the archdiocese to maintain parishioners through changing times, and the experiences of these parishioners can be used to develop better policies in the future.

description: We investigate, if the cosmic ray positron fraction, as reported by the HEAT and AMS collaborations, is compatible with the annihilation of neutralinos in the supergravity inspired Constrained Minimal Supersymmetric Model (CMSSM), thus complementing previous investigations, which did not consider constraints from unification, electroweak symmetry breaking and the present Higgs limits at LEP. We perform a global fit of all SUSY parameters to low energy constraints and find that in the acceptable parameter regions the neutralino annihilation into b-bbar quark pairs is the dominant channel and improves the fit to the experimental positron fraction data considerably with respect to a fit with background only. These fits are comparable to the fit for regions of parameter space, where the annihilation into W^+ W^- pairs dominates. However, these latter regions are ruled out by the present Higgs limit of 114 GeV from LEP in combination with b->s gamma data.
