title: Comparing Scaling Approaches to Estimate Unimpaired Streamflow Timeseries and Seasonal Flow Metrics at Ungauged Streams
Creators: name: Christensen, Karl
Publisher: name: Utah State University
Year: 2023

description: River ecosystems are controlled in part by natural variation in the flow regime and streamflow alterations that impair these natural variations often have negative impacts for aquatic species. Flow metrics describing attributes of the natural flow regime can inform environmental water management goals to maintain and restore river ecosystems by mirroring critical aspects of the natural flow regime. However, unimpaired daily streamflow data needed to calculate these flow metrics is not always readily available. Statistical scaling approaches present an opportunity to estimate unimpaired flow metrics at ungauged locations to better address environmental water management objectives. This study evaluates a suite of scaling approaches for their ability to estimate ecologically significant daily unimpaired flow metrics applied across the State of California. Results demonstrate the utility of stratification by hydrologic and water-year-type to improve statistical scaling methods and indicate that different scaling approaches are better suited to estimate certain flow metrics. Aggregated dimensionless reference hydrographs accounted for spatial and inter-annual variability better than a single index site for improved representation across large regions. This is the first known example of combining hydrologic classifications and stream class stratified reference hydrographs to refine scaling streamflow relationships and capture natural streamflow magnitude and timing patterns across a large heterogeneous region. Results are intended to inform selection of appropriate streamflow scaling approaches for a given study region based on the specific flow metrics of interest, stream classes present, and reference gauge density and distribution. Better prediction of unimpaired daily flow metrics will lead to more accurate streamflow regime characterization and better flow management decisions.
Strategies for Trade Liberalization in the Americas: A Report to ECLAC

description: The formation of trading blocks can help or hinder the global liberalization of trade. A determining factor is whether trade within the block is organized around traditional comparative advantages, or around economies of scale. The issue is of particular importance for NAFTA, and for a potential American free trade zone. Regional free trade agreements such as NAFTA can be either complements to, or substitutes for, the GATT negotiations. They are substitutes when the regional agreements are based on traditional comparative advantages, with each regional market developing market power and the corresponding economic incentives to impose tariffs on the rest of the world. Alternatively, regional trade agreements can be complementary to global trade negotiations. This occurs when the trading blocks lead to trade based on the exploitation of economies of scale, rather than to trade based on traditional comparative advantage. Economies of scale produce incentives for expanded trade, and these can defeat the usual "optimal tariff" incentives to impose tariffs and restrict trade. Economies of scale can also mitigate another negative feature of trading blocks: their tendency to divert trade from efficient to inefficient sources. The emergence of regional blocks organized around economies of scale can thus lead to increasingly open international markets. We discuss policy implications for free trade in the Americas.
Optimal phenotypic plasticity in a stochastic environment minimizes the cost/benefit ratio

description: This paper addresses the question of optimal phenotypic plasticity as a response to environmental fluctuations while optimizing the cost/benefit ratio, where the cost is energetic expense of plasticity, and benefit is fitness. The dispersion matrix Σof the genes' response (H = ln|Σ|) is used: (i) in a numerical model as a metric of the phenotypic variance reduction in the course of fitness optimization, then (ii) in an analytical model, in order to optimize parameters under the constraint of limited energy availability. Results lead to speculate that such optimized organisms should maximize their exergy and thus the direct/indirect work they exert on the habitat. It is shown that the optimal cost/benefit ratio belongs to an interval in which differences between individuals should not substantially modify their fitness. Consequently, even in the case of an ideal population, close to the optimal plasticity, a certain level of genetic diversity should be long conserved, and a part, still to be determined, of intra-populations genetic diversity probably stem from environment fluctuations. Species confronted to monotonous factors should be less plastic than vicariant species experiencing heterogeneous environments. Analogies with the MaxEnt algorithm of E.T. Jaynes (1957) are discussed, leading to the conjecture that this method may be applied even in case of multivariate but non multinormal distributions of the responses.
Sensitivity of Seasonal Climate Forecasts to Persisted SST Anomalies

description: Most estimates of the skill of atmospheric general circulation models (AGCMs) for forecasting seasonal climate anomalies have been based on simulations with actual observed sea surface temperatures (SSTs) as lower boundary forcing. Similarly estimates of the climatological response characteristics of AGCMs used for seasonal-to-interannual climate prediction frequently rest on historical simulations using "perfect" SST forecasts. This paper examines the errors and biases introduced into the seasonal climate response of an AGCM forced with persisted SST anomalies, which are generally considered to constitute a good prediction of SST in the first 3-month season. However, the added uncertainty introduced by the predicted SST anomalies weakens, and in some cases nullifies, the skill of atmospheric predictions that is possible given perfect SST forcing. The use of persisted SST anomalies also leads to changes in local signal-to-noise characteristics. Thus, it is argued that seasonal-to-interannual forecasts using AGCMs should be interpreted relative to historical runs that were subject to the same strategy of boundary forcing used in the current forecast in order to properly account for errors and biases introduced by the particular SST prediction strategy. Two case studies are examined to illustrate how the sensitivity of the climate response to predicted SSTs may be used as a diagnostic to suggest improvements to the predicted SSTs.

description: In the present paper the transport of impurities driven by trapped electron (TE) mode turbulence is studied. Non-linear (NL) gyrokinetic simulations using the code GENE are compared with results from quasilinear (QL) gyrokinetic simulations and a computationally efficient fluid model. The main focus is on model comparisons for electron temperature gra- dient driven turbulence regarding the sign of the convective impurity velocity (pinch) and the impurity density gradient R/LnZ (peaking factor) for zero impurity flux. In particular, the scaling of the impurity peaking factors with impurity charge Z and with driving temper- ature gradient is investigated and compared with the results for Ion Temperature Gradient (ITG) driven turbulence. In addition, the impurity peaking is compared to the main ion peaking obtained by a self-consistent fluid calculation of the density gradients corresponding to zero particle fluxes. For the scaling of the peaking factor with impurity charge Z, a weak dependence is obtained from NL GENE and fluid simulations. The QL GENE results show a stronger dependence for low Z impurities and overestimates the peaking factor by up to a factor of two in this region. As in the case of ITG dominated turbulence, the peaking factors saturate as Z increases, at a level much below neoclassical predictions. However, the scaling with Z is weak or reversed as compared to the ITG case. The scaling of impurity peaking with the background temperature gradients is found to be weak in the NL GENE and fluid simulations. The QL results are also here found to significantly overestimate the peaking factor for low Z values. For the parameters considered, the background density gradient for zero particle flux is found to be slightly larger than the corresponding impurity zero flux gradient.

description: Consider an exchange economy with multiple competitive equilibria. Agents know the set of equilibria, but not which will be selected. To insure against unfavorable equilibrium outcomes, they trade on markets for commodities contingent on the equilibrium price vector. Such price-contingent contracts allow agents to insure fully against the risk stemming from uncertainty about the equilibrium to be chosen. However they introduce further uncertainty because there may be several possible equilibrium prices for price-index-contingent commodities. The introduction of higher-order of derivative products removes this uncertainty, but in turn introduces uncertainty about the prices of these products. We prove that in regular economies this process converges in a finite number of steps to a unique fully-insured Pareto efficient allocation. The introduction of price-contingent commodities or securities and further derivative securities removes all endogenous uncertainty associated with lack of knowledge of equilibrium prices. We thus provide a mechanism for resolving non-uniqueness in economies with multiple equilibria and also give an important resource-allocation role to derivative securities based on price indices.

The SUSY flavor problem can be avoided due to contact terms in the 4D effective Kähler potential peculiar to the multi-moduli case. A detailed phenomenological analysis is provided based on an illustrative model.

description: The paper establishes a clear connection between equilibrium theory and social choice theory by showing that, for a well defined social choice problem, the conditions which are necessary and sufficient to establish existence of a competitive equilibrium. We define a condition of limited arbitrage on the preferences and the endowments of an Arrow-Debreu economy. This bounds the utility gains that the traders can afford from their initial endowments. Theorem 2 proves that limited arbitrage is necessary and sufficient for the existence of a social choice rule which allocates society's resources among individuals in a manner which depends continuously and anonymously on their preferences over allocations, and which respects unanimity. Limited arbitrage is also necessary and sufficient for the existence of a competitive equilibrium in the Arrow-Debreu economy, with or without bounds on short sales, Theorem 7. Theorem 4 proves that any market allocation can be achieved as a social choice allocation, i.e. an allocation which is maximal among all feasible allocations according to a social preference defined via a social choice rule which is continuous, anonymous and respects unanimity.
A comparative life cycle assessment of mid-rise office building construction alternatives : laminated timber or reinforced concrete
Creators: name: Robertson, Adam Blake
Publisher: name: University of British Columbia
Year: 2011

description: The objective of this project aimed to quantify and compare the environmental impacts associated with the construction of a mid-rise office building. Two alternative scenarios were considered; a traditional cast-in-place, reinforced concrete frame and a laminated timber hybrid design, which utilized engineered wood products including glulam and cross-laminated timber (CLT). The study boundary was cradle-to-gate and encompassed the structural support system and the building enclosure. A case study building; Discovery Place – Building 12, was selected to represent a typical five-storey office building constructed in North America. Floor plans, elevations, material quantities and design loads associated with the concrete-framed building design were obtained from issued-for-construction engineering drawings. A functionally equivalent, laminated timber design was then conceived, based on the requirements outlined in CAN/CSA-O86-01. Design values for locally produced CLT panels were established from in-house material testing results. A life cycle assessment of CLT, manufactured in British Columbia with mountain pine beetle killed wood, was developed based on primary inventory data collected from a pilot-scale manufacturing facility. Life cycle inventory and impact assessment data for building materials was obtained from secondary sources including BEES® 4.0, ATHENA® EcoCalculator, CORRIM, and the US LCI. TRACI, an impact assessment characterization methodology, was employed to translate inventory flows into environmental impact indicators. The environmental comparison of building design alternatives was based on 11 impact categories. The results concluded that the laminated timber building design was associated with a lower environmental footprint in 10 of 11 categories. At a minimum, the heavy timber design demonstrated a 14% improvement, when considering acidification potential. At a maximum, the timber design exhibited a global warming potential that was 71% less than the concrete design. Fossil fuel depletion was the only category where the concrete design was superior, displaying a 6% advantage over the timber scenario. The cumulative embodied energy of construction materials was also calculated; with results estimating energy contents of 116 and 66 terajoules for the timber and concrete designs, respectively. The concrete building acquired 20% of its energy from renewable sources, whereas in the timber-framed case, renewables accounted for over 60% of the combined feedstock and process energy.

description: Classroom instruction is influenced by and reflects teachers’ conceptions about their teaching. In elementary Dual Language Immersion (DLI) classrooms, teachers deliver mathematics and target-language instruction with the expectation that both can be developed concurrently. This qualitative study investigated K-3 Spanish DLI teachers’ conceptions about Mathematics-Focused Content-Based Language Teaching (MF-CBLT), which emphasizes the instructional parameters guiding teachers’ integration of content (mathematics), language (Spanish), and teaching (pedagogy).
The study examined 11 teachers’ statements and teaching samples to investigate their knowledge, beliefs, and preferences (i.e., conceptions) about MF-CBLT. A survey and individual teacher interviews provided access to what teachers had to say while video samples of classroom instruction showed what they did. The collected data were analyzed using open codes and the predetermined codes from MF-CBLT Priorities (preparation, comprehensible input, authentic tasks, practice and application, and integration).
Three major research findings summarize the teachers’ conceptions about MF-CBLT. The first two findings reported teachers’ common conceptions as primarily pedagogy-focused and secondarily mathematics-focused. The third major finding revealed more varied and inconsistent conceptions about integrating Spanish language development within mathematics instruction during MF-CBLT.
Possible explanations for teachers’ common and more varied conceptions about MF-CBLT are explored and discussed, including apparent inconsistencies about language integration. With only a few participants and possible bias in interpreting their conceptions, the study nonetheless offers insights that can inform current and future practice. The study contributes to the literature base on MF-CBLT in DLI and offers suggestions for mathematics professional development for DLI teachers.

description: Recent advances in high-throughput biotechnologies have provided an unprecedented opportunity for biomarker discovery, which, from a statistical point of view, can be cast as a variable selection problem. This problem is challenging due to the high-dimensional and nonlinear nature of omics data and, in general, it suffers three difficulties: (i) an unknown functional form of the nonlinear system, (ii) variable selection consistency, and (iii) high-demanding computation. To circumvent the first difficulty, we employ a feed-forward neural network to approximate the unknown nonlinear function motivated by its universal approximation ability. To circumvent the second difficulty, we conduct structure selection for the neural network, which induces variable selection, by choosing appropriate prior distributions that lead to the consistency of variable selection. To circumvent the third difficulty, we implement the population stochastic approximation Monte Carlo algorithm, a parallel adaptive Markov Chain Monte Carlo algorithm, on the OpenMP platform that provides a linear speedup for the simulation with the number of cores of the computer. The numerical results indicate that the proposed method can work very well for identification of relevant variables for high-dimensional nonlinear systems. The proposed method is successfully applied to identification of the genes that are associated with anticancer drug sensitivities based on the data collected in the cancer cell line encyclopedia study. Supplementary materials for this article are available online.
Commodity-Price Destabilizing, Commodity Price Stabilization
Creators: name: McLaren, John
Publisher: name: Columbia University
Year: 1993
Subjects: Economics

description: In buffer stocks established by International Commodity Agreements, typically the buffer stock manager (BSM) is given: (i) inadequate resources to defend the price floor on her own; (ii) considerable discretion in day-to-day operations. These two features are shown to imply that the buffer stock can as easily add volatility to the market as remove it. Fact (i) implies that the BSM needs to use speculators: the floor will be defended only if speculators "bet" on the buffer stock's success can become self-fulfilling prophecies. This open the way for the price to fluctuate in response to "sunspots," or intrinsically irrelevant phenomena, which would have been impossible without the buffer stock. The theory is given anecdotal support from the markets for tin and natural rubber.
The recent transformation of participatory employment practices in Japan

description: Using both quantitative data from national surveys and qualitative data from our own field research, this paper provides evidence on the responses of Japanese firms in their use of participatory employment practices to the economic slowdown in the 1990s in general and the recent financial crisis in particular. Overall, consistent with the complementarity of such practices and the long-term nature of their effects, evidence points to their enduring nature. The exceptions are small to medium size firms with no union; with them we find evidence for management to try to weaken the role of employee participation. There are, however, a few early signs of trouble even for large, unionized firms, which might eventually result in the breakdown of the system if left untreated. First, while the number of full time union officials has been falling substantially as a result of continued downsizing of the firm's labor force, the amount of time and effort that union officials need to put into participatory employment practices have not been falling. This often results in an uncompensated increase in workload for union officials. If this trend continues, union officials who have been playing a key role in Japanese participatory management will become less effective and less committed to the interest of the rank and file. Second, top management sometimes finds its participatory management system detrimental to timely and efficient management, and hence tries to streamline the system. Overloaded union officials may offer less resistance to this kind of initiative. Third, the current system tends to produce a gap in the quantity and quality of information acquired from management between top union officials and their general membership. It is conceivable that such a gap may eventually result in the breakdown of the system.
From cozy regulation to competitive markets: The regime shift of Japan's financial system

description: The Japanese banking and financial systems arc substantially along the transformation process of shifting from one regime to a new one. The "postwar" financial regime was characterized by extraordinarily high priority placed by the Japanese regulators on financial system safety. To that end they restricted capital market development, and established the conditions in which no bank could fail: deposits and loans to business as the predominant financial instruments; wide interest rate spreads; no entry and no exit mechanisms; close, informal, opaque, administrative guidance by the Ministry of Finance with little disclosure, is what evolved into a cozy, collusive, nontransparent relationship between regulator and those regulated... in other words, the cliche "bank convoy system." This protected system gradually dissolved once growth in the Japanese economy in the mid 1970s shifted from being supply constrained to inadequate aggregate demand constrained. With credit becoming easily available, deregulation began its very slow, piecemeal, gradual process, evolving to the new financial system regime today based in principle on open, free, competitive financial markets. The transformation was complicated and made much more expensive by the stock and urban real estate bubbles of the late 1980s, the bursting of which destroyed the collateral value of loans, compounded by Japan's miserable economic performance of the 1990s. Today Japan's financial system rests on highly competitive capital and loan markets, with Japanese financial institutions weak and engaged in consolidation, and many major foreign financial institutions as active players in many Japanese wholesale financial markets.

description: We study the morphology of a fluid membrane in spherical confinement. When the area of the membrane is slightly larger than the area of the outer container, a single axisymmetric invagination is observed. For higher area, self-contact occurs: the invagination breaks symmetry and deforms into an ellipsoid-like shape connected to its outer part via a small slit. For even higher areas, a second invagination forms inside the original invagination. The folding patterns observed could constitute basic building blocks in the morphogenesis of biological tissues and organelles.

description: O presente trabalho é um estudo dos usos sociais das previsões climáticas no Estado do Ceará, Nordeste Brasileiro. Inicialmente textos importantes e de publicação recente em língua inglesa são apresentados e sumarizados. A bibliografia é em geral consensual em argumentar que as expectativas sociais com relação aos benefícios provenientes da aplicação de previsões climáticas são inconsistentes com fatores limitantes existentes nas circunstancias em que prognósticos de clima são utilizados. Tais fatores podem ser classificados como restrições ligadas a incompatibilidades de modelos mentais e esquemas de pensamento, e incompatibilidades operacionais e organizacionais. Dentro da primeira classe encontramos questões como formas locais específicas de entendimento de fenômenos climáticos, dificuldades no uso de informações probabilísticas, ruídos comunicativos provenientes do uso de jargão técnico na disseminação massificada de prognósticos, e formas distintas e mesmo antagônicas de conceber os benefícios sociais e econômicos provenientes do uso da informação do clima. Dentro das incompatibilidades operacionais e organizacionais encontramos problemas de descompasso entre escalas e padrões espaciais e temporais de decisão, a inerente variabilidade de fenômenos climáticos como o El Niño, a manipulação política de prognósticos de clima, dificuldades em transformar prognósticos de clima em prognósticos de impacto, incompatibilidades entre os graus de incerteza com que fornecedores e usuários da informação do clima trabalham, e a existência de múltiplos prognósticos inconsistentes a gerar crises de confiabilidade e legitimidade ligadas à atividade meteorológica. Argumentamos que as análises são geralmente demasiado superficiais no tratamento de formas locais estabelecidas de interpretação e contextualização das informações de clima, mais especificamente em dois níveis principais: por um lado, no que se refere aos discursos e narrativas religiosos sobre clima, fator presente de forma decisiva na forma como as populações do sertão nordestino se relacionam com o meio ambiente; e por outro, na forma como as dinâmicas sociopolíticas desta região semi-árida, através da "naturalização" da miséria e da vinculação desta aos fenômenos climáticos (isto é, através da explicação da pobreza através de fatores naturais como eventos de seca), criaram através da história uma forma específica de entender o papel social da meteorologia e a responsabilidade desta no gerenciamento do bem estar da população mais vulnerável. Através do uso de material etnográfico, analisamos estas duas questões, e concluímos que a meteorologia deve atuar de forma ativa para alterar padrões coletivos de entendimento de sua missão, seu papel e suas capacidades reais de contribuição com os esforços de adaptação da população às condições do semi-árido.
The Japanese Employment System after the Bubble Burst: New Evidence

description: Taking advantage of our first access to micro data from the 2002 Employment Status Survey (ESS) as well as previous years of the ESS, we provide new evidence on changes in the "lifetime employment" practice which serves as a foundation for a variety of complementary practices of the Japanese employment system. Overall, we find evidence for the resilience of the Japanese employment system. Job stability of regular employees did not fall even after the Japanese economy went deep into prolonged stagnation following the bubble burst. Our cohort analysis of narrowly-defined "lifetime employment" workers (new school graduate hires) also points to the stability of the size of the "lifetime employment" pool over time. To be consistent with the enduring nature of the "lifetime employment" system, we also find some evidence for the buoyancy of other complementary elements of the Japanese employment system. This, however, does not mean the complete rigidity of the Japanese employment system. Apparently the Japanese employment system has evolved in response to Japan's prolonged stagnation. First, job stability of regular employees eventually fell during the final years of the Great Recession. It took years yet the magnitude of the fall turned out to be not negligible and for some groups of workers it was large. Second, the burden of downsizing during Japan's prolonged stagnation fell disproportionately on women as opposed to men and on high-school graduates as opposed to college graduates. The largest fall in job stability was found for female regular employees who were mid-career hires and working for large firms. We interpret our findings as a rational response of Japanese firms that are in dire need for downward employment adjustment yet concerned about the cost of reneging on their implicit long-term employment contracts.

The dominance of this conceptual apparatus in recent decades has left, as its legacy, the worst global financial crisis since the Great Crash of 1929, the worst recession since the Second World War and a collapse of international trade. As a result, the world is also experiencing a mounting social crisis, reflected in particular in escalating unemployment and underemployment, and significant reductions in the value of pension funds. The developing world, which had been experiencing in recent years one of its best growth records in history, has also been dragged into the crisis.
Japan's Economic Recovery Stalled

description: While Japan's economy performed reasonably well in 2007 and through the first quarter of 2008, as of mid-2008 it had, dismayingly, slowed so much and so rapidly that it very likely is now in a recession. The extended recovery and expansion since 2002 has come to an end, and recovery may well not resume until late 2009. Given Japan's increased interdependence with the global economy, as well as domestic factors, uncertainty is greater than usual. At issue are the severity of the downturn and its length before satisfactory growth resumes. Inadequate domestic demand is the major constraint on growth.
Studies investigating evolutionary transitions in plant reproduction

description: In this thesis I explore several topics related to the evolution of plant reproductive characters. First, I consider mating system evolution at a single locus that simultaneously affects multiple fitness components, including pollen export, selfing rate, and viability (i.e., survival or a similar change in male and female function). I use two approaches. First, I assume frequency-independent mating, so the model characterizes prior selfing (Chapter 2). Second, I assume that selfing rates are determined by a "mass action" process, which characterizes several additional modes of selfing (Chapter 3). For both approaches, pleiotropy between increased viability and selfing rate reduces opportunities for the evolution of pure outcrossing, can favor complete selfing despite high inbreeding depression, and notably, can cause the evolution of mixed mating despite very high inbreeding depression. These results suggest that selection by non-pollinating agents may help explain mixed mating, particularly in species with very high inbreeding depression. Second, I analyze the potential for different genome regions to harbor intra-locus sexually-antagonistic polymorphism. Such polymorphism, involving one allele that benefits fitness in males but decreases fitness in females, and a second allele with opposite effects, is believed to influence the evolution of sexual dimorphism and sex chromosome evolution; both have evolved repeatedly among plant lineages, so understanding the potential for sexually-antagonistic variation informs the evolution of dioecy. Numerical analyses confirm the previous major conclusion that sexually-antagonistic polymorphisms are generally maintained in a larger region of parameter space if the locus is in the pseudo-autosomal region than if it is autosomal. Finally, I consider the effect of two stressors on time to flowering to address hypotheses regarding the evolution of flowering time in heterogeneous environments. A greenhouse experiment using Mimulus guttatus revealed that low water and herbivory had opposite effects on time to flowering, although these effects were weak. These stressors had stronger influences on plant height and the number of flowers produced. These data, combined with previously published results, suggest that a stressor's effect on non-phenological traits may influence the evolution of flowering time through mechanisms not considered by previously published theoretical studies.
Irrelevance of the $1-a-Day Poverty Line

description: Whether or not an individual is deemed to be poor depends not merely on that individual's economic and non-economic endowments but also, equally, if not more importantly, the place of that individual in the socio-economic-political processes of the country of which he or she is a citizen. An important implication of this is that any meaningful indicator that distinguishes the poor from non-poor has to be multidimensional. Nonetheless, most widely used indicators, including the $1 a day poverty line, are unidimensional and are usually defined as a person's expenditure on consumption or, less often, income.
Sealing the fate of a fourth generation of fermions

description: The search for the effects of heavy fermions in the extension of the Standard Model with a fourth generation is part of the experimental program of the Tevatron and LHC experiments. Besides being directly produced, these states affect drastically the production and decay properties of the Higgs boson. In this note, we first reemphasize the known fact that in the case of a light and long-lived fourth neutrino, the present collider searches do not permit to exclude a Higgs boson with a mass below the WW threshold. In a second step, we show that the recent results from the ATLAS and CMS collaborations which observe an excess in the $γγ$ and $4\ell^\pm$ search channels corresponding to a Higgs boson with a mass $M_H \approx 125$ GeV, cannot rule out the fourth generation possibility if the $H \to γγ$ decay rate is evaluated when naively implementing the leading ${\cal O}(G_F m_{f'}^2)$ electroweak corrections. Including the exact next-to-leading order electroweak corrections leads to a strong suppression of the $H \to γγ$ rate and makes this channel unobservable with present data. Finally, we point out that the observation by the Tevatron collaborations of a $\gsim 2σ$ excess in the mass range $M_H = 115$-135 GeV in the channel $q\bar q \to WH \to Wb\bar b$ can definitely not be accommodated by the fourth generation fermion scenario. All in all, if the excesses observed at the LHC and the Tevatron are indeed due to a Higgs boson, they unambiguously exclude the perturbative fermionic fourth generation case. In passing, we also point out that the Tevatron excess definitely rules out the fermiophobic Higgs scenario as well as scenarios in which the Higgs couplings to gauge bosons and bottom quarks are significantly reduced.

The impact of the post Cold War crises on the political economy of Japan

Subjects: Economics

description: The three major security crises in the last decade in Japan- the response to the Gulf War, the earthquake in Kobe, and the Sarin chemical attack on Tokyo subway lines- provided the major turning points of Japanese security policy of the post cold war era. These events have also greatly affected Japanese fiscal policy and politics. The lessons from the failed attempt to send Self Defense Forces to the Gulf led to the act of allowing the SDFs' participation in international peacekeeping operations and the new Guideline for "the situation in areas surrounding Japan". The new political coalition which was formed to pass the tax increases in order to finance the Gulf War paved the way to the era of coalition governments in the 1990s and today. The earthquake in Kobe and the Sarin chemical attack made the Japanese people realize the importance of the SDFs in times of catastrophic events. These events, combined with the changes in the international situation, led to the revision of the National Defense Program Outline. These catastrophic events also led to the strengthening of the prime minister's office and some improvements of the law enforcement system. The "construction bonds" principle for fiscal policy was finally broken on the occasion of the Kobe earthquake, and the issuance of government bonds has been accelerated since then. All of these changes relate to the current response of the Koizumi Cabinet to the recent terrorist attacks in America and the Japanese budget deficit. As to the future of both security policy and fiscal policy, the preparedness of the Japanese people to "sacrifice" is important.
