The Politics of Budget Consolidation in Britain and Germany: the Impact of Blame-Avoidance Opportunities. CES Germany & Europe Working Papers, No. 05.2, 2005
According to parts of the literature, blame avoidance opportunities, i.e. the necessity and applicability of blame avoidance strategies, may differ among countries according to the respective institutional set-ups and between governing parties according to their programmatic orientation. In countries with many veto actors, a strategy of "Institutional Cooperation" among these actors is expected to diffuse blame sufficiently to render other blame avoidance strategies obsolete. In contrast, governments in Westminster democracies should resort to the more unilateral strategies of presentation, policy design and timing. At the same time, parties of the left are expected to have an easier time implementing spending cuts while right parties are less vulnerable when proposing tax increases. Evidence from the politics of budget consolidation in Britain and Germany does not corroborate these hypotheses. Instead, it seems that party competition conditions the effects institutions and the partisan complexion of governments have on the politics of blame avoidance

From the Field: Mobile Technologies for Mine Action
Breakthroughs in technology development transformed desktop computers into small, powerful mobile units equipped with intelligent software and extensive possibilities to connect and interact. Alternatively, the world of mine action still depends on manual work done with pen and paper, and the process of field data collection is especially exposed. However, field tests show that the use of mobile technology vastly improves safety and increases the effectiveness of field work. Adapting to new mobile technologies for field data collection will also positively affect the ways in which we gather, share, analyze, monitor and evaluate information
A Retrospective Analysis of the Impact of Wind Power Generation on Residential Natural Gas Prices in the United States
Heightened concern over the environmental impact and price volatility of natural gas has led to an increased demand for renewable energy. Wind energy is one of the fastest-growing sources of electricity and is the United States’ top renewable energy source. As a substitute for natural gas, wind energy has a direct impact on the demand for natural gas and consequently, the price. Using data from the U.S. Energy Information Administration, the Bureau of Economic Analysis, and the U.S. NOAA, this paper determines a causal relationship between wind generation and natural gas prices because of the random component of weather. Employing an ordinary least squares regression with a fixed effect controlling for the month and state, I conclude that a one-percent increase in wind generation leads to a 1.80 percent drop in residential natural gas prices
Creating a System for Citizen Participation: How the Nonprofit Sector Can Provide Citizens a Voice in Tokyo\u27s Urban Development System
Recent changes in Japan’s civil society together with the current political and economic environment have created the first opportunity to develop a viable nonprofit sector that represents citizen interests and allows for public participation in Tokyo’s urban development scheme. Tokyo’s urban environment has failed to meet the social and cultural needs of its citizens due to unprecedented economic and industrial growth from the beginning of the Meiji era until the 1990s. Through this extended period of growth, the goal for urban development was solely to increase Tokyo’s economic strength, while social needs were not addressed. While the City Planning Law of 1968 (“CPL”) sought to require citizen participation in urban planning, the law was largely ineffective due to its narrow scope and weak legal remedies. During much of the twentieth century, Tokyo’s governance was controlled by an iron triangle comprised of bureaucracy, government, and big business, which drove Tokyo’s economic growth. This form of governance did not allow citizens to participate in the political process. The iron triangle lost its strength only after the collapse of the economic bubble in the 1990s. With urban development failing to meet the needs of the citizens and the iron triangle having lost its strength, citizens groups began to assert more influence over the city’s governance. Successes for the citizens groups and growing media attention prompted the promulgation of the Nonprofit Organizations Law of 1998 (“NPO Law”). The NPO Law created a framework for a nonprofit sector and began to strengthen its legitimacy. Unlike past attempts to introduce a viable nonprofit sector, the NPO Law came at a time when the political and economic environments of the city allowed for outside influence in the political process. While the foundation has now been laid for a viable nonprofit sector, the sector must gain legitimacy and independence before it is a truly viable means to public participation. With increased legitimacy and independence, Japan’s nonprofit sector will serve to improve the urban development scheme by balancing the interests of citizens and corporations and meet long-standing social goals
Overexpression of Mcl-1 exacerbates lymphocyte accumulation and autoimmune kidney disease in lpr mice
Cell death by apoptosis has a critical role during embryonic development and in maintaining tissue homeostasis. In mammals,
there are two converging apoptosis pathways: the ‘extrinsic’ pathway, which is triggered by engagement of cell surface ‘death
receptors’ such as Fas/APO-1; and the ‘intrinsic’ pathway, which is triggered by diverse cellular stresses, and is regulated by prosurvival
and pro-apoptotic members of the Bcl-2 family of proteins. Pro-survival Mcl-1, which can block activation of the proapoptotic
proteins, Bax and Bak, appears critical for the survival and maintenance of multiple haemopoietic cell types. To
investigate the impact on haemopoiesis of simultaneously inhibiting both apoptosis pathways, we introduced the vavP-Mcl-1
transgene, which causes overexpression of Mcl-1 protein in all haemopoietic lineages, into Faslpr/lpr mice, which lack functional
Fas and are prone to autoimmunity. The combined mutations had a modest impact on myelopoiesis, primarily an increase in the
macrophage/monocyte population in Mcl-1tg/lpr mice compared with lpr or Mcl-1tg mice. The impact on lymphopoiesis was
striking, with a marked elevation in all major lymphoid subsets, including the non-conventional double-negative (DN) T cells
(TCRβ+
CD4–
CD8–
B220+
) characteristic of Faslpr/lpr mice. Of note, the onset of autoimmunity was markedly accelerated in Mcl-1tg/lpr
mice compared with lpr mice, and this was preceded by an increase in immunoglobulin (Ig)-producing cells and circulating
autoantibodies. This degree of impact was surprising, given the relatively mild phenotype conferred by the vavP-Mcl-1 transgene
by itself: a two- to threefold elevation of peripheral B and T cells, no significant increase in the non-conventional DN T-cell
population and no autoimmune disease. Comparison of the phenotype with that of other susceptible mice suggests that the
development of autoimmune disease in Mcl-1tg/lpr mice may be influenced not only by Ig-producing cells but also other
haemopoietic cell types
B cell-intrinsic function of TAPP adaptors in controlling germinal center responses and autoantibody production in mice
Control of B-cell signal transduction is critical to prevent production of pathological autoantibodies. Tandem PH domain containing proteins (TAPPs) specifically bind PI(3,4)P2, a phosphoinositide product generated by PI 3-kinases and the phosphatase SHIP. TAPP KI mice bearing PH domain-inactivating mutations in both TAPP1 and TAPP2 genes, uncoupling them from PI(3,4)P2, exhibit increased BCR-induced activation of the kinase Akt and develop lupus-like characteristics including anti-DNA antibodies and deposition of immune complexes in kidneys. Here we find that TAPP KI mice develop chronic germinal centers (GCs) with age and show abnormal expression of B cell activation and memory markers. Upon immunization with T-dependent Ag, TAPP KI mice develop functional but abnormally large GCs, associated with increased GC B cell survival. Disruption of chronic GCs in TAPP KI mice by deletion of the costimulatory molecule ICOS abrogate anti-DNA and anti-nuclear antibody production in TAPP KI mice, indicating an essential role for GCs. Moreover, TAPP KI B cells are sufficient to drive chronic GC responses and recapitulate the autoimmune phenotype in bone marrow chimeric mice. Our findings demonstrate a B cell-intrinsic role of TAPP-PI(3,4)P2 interaction in regulating GC responses and autoantibody production and suggest that uncontrolled Akt activity in B cells can drive autoimmunity.

Long-Run Effects of Dynamically Assigned Treatments:A New Methodology and an Evaluation of Training Effects on Earnings
We propose and implement a new method to estimate treatment effects in settings where individuals need to be in a certain state (e.g., unemployment) to be eligible for a treatment, treatments may commence at different points in time, and the outcome of interest is realized after the individual left the initial state. An example concerns the effect of training on earnings in subsequent employment. Any evaluation needs to take into account that some of those who are not trained at a certain time in unemployment will leave unemployment before training while others will be trained later. We are interested in effects of the treatment at a certain elapsed duration compared to "no treatment at any subsequent duration." We prove identification under unconfoundedness and propose inverse probability weighting estimators. A key feature is that weights given to outcome observations of nontreated depend on the remaining time in the initial state. We study effects of a training program for unemployed workers in Sweden. Estimates are positive and sizeable, exceeding those obtained with common static methods. This calls for a reappraisal of training as a tool to bring unemployed back to work
Innate immunodeficiency following genetic ablation of Mcl1 in natural killer cells
The cytokine IL-15 is required for natural killer (NK) cell homeostasis; however, the intrinsic mechanism governing this requirement remains unexplored. Here we identify the absolute requirement for myeloid cell leukaemia sequence-1 (Mcl1) in the sustained survival of NK cells in vivo. Mcl1 is highly expressed in NK cells and regulated by IL-15 in a dose-dependent manner via STAT5 phosphorylation and subsequent binding to the 3'-UTR of Mcl1. Specific deletion of Mcl1 in NK cells results in the absolute loss of NK cells from all tissues owing to a failure to antagonize pro-apoptotic proteins in the outer mitochondrial membrane. This NK lymphopenia results in mice succumbing to multiorgan melanoma metastases, being permissive to allogeneic transplantation and being resistant to toxic shock following polymicrobial sepsis challenge. These results clearly demonstrate a non-redundant pathway linking IL-15 to Mcl1 in the maintenance of NK cells and innate immune responses in vivo
