How do Electoral Systems Affect Fiscal Policy? Evidence from State and Local Governments, 1890 to 2005
Using a new data set on Swiss state and local governments from 1890 to today, we analyze how the adoption of proportional representation affects fiscal policy. We show that proportional systems shift spending toward broad goods (e.g. education and welfare benefits) but decrease spending on targetable goods (e.g. roads and agricultural subsidies). Our evidence does not suggest that proportional representation increases the overall size of government. We provide new evidence on the mechanism behind these estimates. We show that proportional elections lead to better political representation of left-wing parties, which are associated with more spending. Furthermore, proportional elections lead to higher political fragmentation. However, since political fragmentation increases spending in a plurality system only, proportional elections reduce spending through its more moderate effects of fractionalized parliaments.electoral system, public finance, political fragmentation, matching
Does direct democracy reduce the size of government? New evidence from historical data, 1890-2000
Using historical data for all Swiss cantons from 1890 to 2000, we estimate the causal effect of direct democracy on government spending. The main innovation in this paper is that we use fixed effects to control for unobserved heterogeneity and instrumental variables to address the potential endogeneity of institutions. We find that the budget referendum and lower costs to launch a voter initiative are effective tools in reducing canton level spending. However, we find no evidence that the budget referendum results in more decentralized government or a larger local government. Our instrumental variable estimates suggest that a mandatory budget referendum reduces the size of canton spending between 13 and 19 percent. A 1 percent lower signature requirement for the initiative reduces canton spending by up to 2 percent.Direct Democracy, Fiscal Policy, Switzerland
Does Direct Democracy Reduce the Size of Government? New Evidence from Historical Data, 1890-2000
Using a new dataset of Swiss cantons from 1890 to 2000, we estimate the causal effect of direct democracy on government spending. Our analysis is novel in two ways: first, we use fixed effects to control for unobserved heterogeneity; second, we combine a new instrument with fixed effects to address the potential endogeneity of institutional reform. We find that direct democracy has a constraining, but modest effect on spending. Our estimates suggest that a mandatory budget referendum reduces canton expenditures by 9 percent. A decline in the signature requirement for the voter initiative by one percent reduces spending by 2.2 percent. We find no evidence that direct democracy at the canton level results in higher local spending or a more decentralized government.
Gender gaps in policy making: Evidence from direct democracy in Switzerland
In spite of increasing representation of women in politics, little is known about their impact on policies. Comparing outcomes of parliaments with different shares of female members does not identify their causal impact because of possible differences in the underlying electorate. This paper uses a unique data set on voting decisions to sheds new light on gender gaps in policy making. Our analysis focuses on Switzerland, where all citizens can directly decide on a broad range of policies in referendums and initiatives. We show that there are large gender gaps in the areas of health, environmental protection, defense spending and welfare policy which typically persist even conditional on socio-economic characteristics. We also find that female policy makers have a substantial effect on the composition of public spending, but a small effect on the overall size of government.Female Policy Makers, Political Gender Gaps, Switzerland
Gender gaps in policy making: evidence from direct democracy in Switzerland
This paper uses a unique data set on individual voting decisions to shed new light on gender gaps in policy making. Our analysis focuses on Switzerland, the world leader in direct democracy, where all citizens directly decide on a broad range of policies at the ballot box. Analysing all federal votes held between 1981 and 2003, we show that there are large gender gaps in the areas of health, environmental protection, defence spending and welfare policy. The gender gaps typically persist even conditional on socio-economic characteristics. We also find that female policy-makers have a substantial effect on the composition of public spending, but a small effect on the overall size of governmen
Subcellular Trafficking and Functional Relationship of the HSV-1 Glycoproteins N and M
The herpes simplex virus type 1 (HSV-1) glycoprotein N (gN/UL49.5) is a type I transmembrane protein conserved throughout the herpesvirus family. gN is a resident of the endoplasmic reticulum that in the presence of gM is translocated to the trans Golgi network. gM and gN are covalently linked by a single disulphide bond formed between cysteine 46 of gN and cysteine 59 of gM. Exit of gN from the endoplasmic reticulum requires the N-terminal core of gM composed of eight transmembrane domains but is independent of the C-terminal extension of gM. Co-transport of gN and gM to the trans Golgi network also occurs upon replacement of conserved cysteines in gM and gN, suggesting that their physical interaction is mediated by covalent and non-covalent forces. Deletion of gN/UL49.5 using bacterial artificial chromosome (BAC) mutagenesis generated mutant viruses with wild-type growth behaviour, while full deletion of gM/UL10 resulted in an attenuated phenotype. Deletion of gN/UL49.5 in conjunction with various gM/UL10 mutants reduced average plaque sizes to the same extent as either single gM/UL10 mutant, indicating that gN is nonessential for the function performed by gM. We propose that gN functions in gM-dependent as well as gM-independent processes during which it is complemented by other viral factors

Alternative Key Schedules for the AES
The AES block cipher is today the most important and analyzed symmetric algorithm. While all versions of the AES are known to be secure in the single-key setting, this is not the case in the related-key scenario. In this article we try to answer the question whether the AES would resist better differential-like related-key attacks if the key schedule was different. For this, we search for alternative permutation-based key schedules by extending the work of Khoo et al. at ToSC 2017 and Derbez et al. at SAC 2018. We first show that the model of Derbez et al. was flawed. Then, we develop different approaches together with MILP-based tools to find good permutations that could be used as the key schedule for AES-128, AES-192 and AES-256. Our methods permitted to find permutations that outperform the permutation exhibited by Khoo et al. for AES-128. Moreover, our new approach based on two MILP models that call one another allowed us to handle a larger search space and thus to search for alternative key schedules for the two bigger versions of AES. This method permitted us to find permutations for AES-192 and AES-256 that provide better resistance to related-key differential attacks. Most importantly, we showed that these variants can resist full-round boomerang attacks
Nuclear egress of TDP-43 and FUS occurs independently of Exportin-1/CRM1
TDP-43 and FUS are nuclear proteins with multiple functions in mRNA processing. They play key roles in ALS (amyotrophic lateral sclerosis) and FTD (frontotemporal dementia), where they are partially lost from the nucleus and aggregate in the cytoplasm of neurons and glial cells. Defects in nucleocytoplasmic transport contribute to this pathology, hence nuclear import of both proteins has been studied in detail. However, their nuclear export routes remain poorly characterized and it is unclear whether aberrant nuclear export contributes to TDP-43 or FUS pathology. Here we show that predicted nuclear export signals in TDP-43 and FUS are non-functional and that both proteins are exported independently of the export receptor CRM1/Exportin-1. Silencing of Exportin-5 or the mRNA export factor Aly/REF, as well as mutations that abrogate RNA-binding do not impair export of TDP-43 and FUS. However, artificially enlarging TDP-43 or FUS impairs their nuclear egress, suggesting that they could leave the nucleus by passive diffusion. Finally, we found that inhibition of transcription causes accelerated nuclear egress of TDP-43, suggesting that newly synthesized RNA retains TDP-43 in the nucleus, limiting its egress into the cytoplasm. Our findings implicate reduced nuclear retention as a possible factor contributing to mislocalization of TDP-43 in ALS/FTD
Differential analysis of the ternary hash function Troika
Troika is a sponge-based hash function designed by Kölbl, Tischhauser, Bogdanov and Derbez in 2019. Its specificity is that it is defined over in order to be used inside IOTA’s distributed ledger but could also serve in all settings requiring the generation of ternary randomness. To be used in practice, Troika needs to be proven secure against state-of-the-art cryptanalysis. However, there are today almost no analysis tools for ternary designs. In this article we take a step in this direction by analyzing the propagation of differential trails of Troika and by providing bounds on the weight of its trails. For this, we adapt a well-known framework for trail search designed for KECCAK and provide new advanced techniques to handle the search on . Our work demonstrates that providing analysis tools for non-binary designs is a highly non-trivial research direction that needs to be enhanced in order to better understand the real security offered by such non-conventional primitives
