Many orthographies include syntactic markers not represented in phonology. In general, to correctly use these syntactic markers, learners have to analyze and understand the syntactic context of the word to be written. Capitalization of nouns, a syntactic marker in German, involves marking heads of noun phrases and is challenging for learners. The aim of this intervention study was to evaluate the effects of syntactic and lexical based trainings on capitalization of nouns. 114 Luxembourgish fifth-graders were assigned to two syntactic groups, a lexical group and a passive control group. The syntactic groups focused on two variants of training syntactic structures within the noun phrase. The lexical group focu-sed on lexical characteristics of nouns and the control group received reading input. The posttest results show that the students in the intervention groups profited from the syntactic-based training. The follow-up test shows that the intervention was sustainable, as the improvement remains stable. The study indicates that a greater focus on syntactic structures can effectively enhance the use of syntactic markers of capitalizations. Although this approach is initially harder to acquire, it covers all cases of capitalization. [less ▲]

This paper addresses the optimization problem of symbol-level precoding (SLP) in the downlink of a multiuser multiple-input multiple-output (MU-MIMO) wireless system while the precoder's output is subject to partially-known distortions. In particular, we assume a linear distortion model with bounded additive noise. The original signal-to-interference- plus-noise ratio (SINR) -constrained SLP problem minimizing the total transmit power is first reformulated as a penalized unconstrained problem, which is referred to as the relaxed robust formulation. We then adopt a worst-case design approach to protect the users' intended symbols and the targeted constructive interference with a desired level of confidence. Due to the non-convexity of the relaxed robust formulation, we propose an iterative algorithm based on the block coordinate ascent-descent method. We show through simulation results that the proposed robust design is flexible in the sense that the CI constraints can be relaxed so as to keep a desirable balance between achievable rate and power consumption. Remarkably, the new formulation yields more energy-efficient solutions for appropriate choices of the relaxation parameter, compared to the original problem. [less ▲]

What is the relationship between the economy’s long-run growth rate, its capital-income ratio, and its factor income distribution? We argue that a satisfactory answer must be derived in an analytical framework that treats the growth and the savings rate as endogenous. From this perspective we scrutinize Piketty’s (2014) theory put forth in his book Capital in the Twenty-First Century in a richly parameterized variant of Romer’s (1990) seminal model with and without population growth. The economy’s growth and its savings rate are exogenous in Piketty’s theory and endogenous in Romer’s. We find that a smaller long-run growth rate may be associated with a smaller capital-income ratio. Hence, the key implication of Piketty’s Second Fundamental Law of Capitalism does not hold. Moreover, in contrast to Piketty’s theory, a smaller long-run growth rate may go together with a greater or a smaller capital share. [less ▲]

Cytosolic caspase-8 is a mediator of death receptor signaling. While caspase-8 expression is lost in some tumors, it is increased in others, indicating a conditional pro-survival function of caspase-8 in cancer. Here, we show that tumor cells employ DNA-damage-induced nuclear caspase-8 to override the p53-dependent G2/M cell-cycle checkpoint. Caspase-8 is upregulated and localized to the nucleus in multiple human cancers, correlating with treatment resistance and poor clinical outcome. Depletion of caspase-8 causes G2/M arrest, stabilization of p53, and induction of p53-dependent intrinsic apoptosis in tumor cells. In the nucleus, caspase-8 cleaves and inactivates the ubiquitin-specific peptidase 28 (USP28), preventing USP28 from de-ubiquitinating and stabilizing wild-type p53. This results in de facto p53 protein loss, switching cell fate from apoptosis toward mitosis. In summary, our work identifies a non-canonical role of caspase-8 exploited by cancer cells to override the p53-dependent G2/M cell-cycle checkpoint. [less ▲]

In the Greater Region SaarLorLux, which consists of Lorraine, Luxembourg, Rhineland-Palatinate, Saarland and Wallonia, the beginnings of beer date back to the Roman occupation. At first, beer was brewed mainly in monasteries. The oldest evidence of a monastic brewery is found in Lorraine, dating from 771 BC, and in Luxembourg only from around 1300. In both regions, religious institutions were the main type of brewery until the industrialization. The first evidence of a municipal brewery dates back to the 12th century; in the beginning, these breweries did not compete with the monasteries. In Wallonia, too, monastic breweries developed until the French occupation, and hence secularisation, brought the business to a halt from 1794. Today, most of the remaining breweries in the Greater Region are part of international groups. There are still a few independent breweries, such as in Rhineland-Palatinate and Saarland, where one of Germany's largest brewing groups, the Karlsberg Group, dominates the industry. In addition to these national companies, since the 1980s, microbreweries have begun to emerge with an exclusively local scope. They ensure that local brewing techniques are not lost. [less ▲]

This paper examines how practice-theoretical considerations can be linked with those of a spatial-theoretical nature and translated into a heuristic of spatial analysis from a cultural studies perspec-tive. This question focus results from the understanding that space should be regarded as an emer-gent aspect of the social and that it is still largely insufficiently defined in Border Studies. Drawing on a number of different spatial concepts, the paper first presents an action-theoretical notion of space and reformulates it in a practice-theoretical framework. It constitutes the point of departure for the development of the spaces of the border model with its analytical categories of social practices, practical knowledge as well as physical-material and social-structural aspects. The diversity of con-nections between these analytical categories have proven to be heuristically particularly useful. [less ▲]

We examine the role of institutional investors in initial coin offerings (ICOs). Taking a financial investor's perspective, we assess the determinants of post-ICO performance via buy-and-hold abnormal returns (BHAR) in a sample of 565 ICO ventures. Conceptually, we argue that institutional investors' superior screening (selection effect) and coaching abilities (treatment effect) enable them to partly overcome the information asymmetry of the ICO context and extract informational rents from their ICO investments. We find that institutional investor backing is indeed associated with higher post-ICO performance. Disentangling selection and treatment effects econometrically, we find that both of these effects explain the positive impact institutional investors have on post-ICO performance. Overall, our results highlight the importance of institutional investors in the ICO context. [less ▲]
