Coordinate Structures

This paper takes into account some asymmetries found in Medieval Portuguese coordinate structures containing infinitival clauses. These are cases of coordination of a non-inflected infinitive with an inflected one and cases of apparent extraction of an element from the first clause of a coordinate structure. Both asymmetries can be eliminated if we assume that the coordination takes place at a higher structural level than that of the infinitival clauses; however, this solution entails that we have to postulate a gap in the second conjunct with the ellipsis of some elements (and/or the presence of some abstract elements) recoverable on the basis of elements expressed in the first conjunct. We show that only this more abstract hypothesis can explain in a direct manner the data examined in this work.

In this paper, we introduce what we consider to be a new problem for syntactic analysis. We show that German allows for discontinuous coordination of DPs, where material that is not part of the coordinate structure may intervene between the DP-coordinates. We further argue that discontinuous coordination of DPs differs from standard DP-coordination in one important aspect: The coordinate structure as a whole is not accessible to material c-commanded by the first coordinate in overt syntax. This difference is a non-trivial problem for any analysis of discontinuous DP-coordination. Keywords: coordinate structures; discontinuous constituents; DP-coordination; German syntax; linear order

Coordinate Structure Constraint

Abstract This paper proposes that adjunct island effects (Ross, 1967; Cattell, 1976) receive a discourse-semantic explanation. The exact formulation of this explanation builds upon previous work (e.g. Kehler, 2002) on island effects of conjuncts (Ross, 1967), which explains asymmetrical extraction from coordinate structures in English (that is, violations of the coordinate structure constraint) in terms of certain coherence relations (Hobbs, 1979). I show that asymmetric extraction from adjuncts in Chinese (that is, violations of the adjunct island constraint) is also sensitive to coherence relations. I argue that such similarities exist because coherence relations may be expressed by either a coordinative or a subordinative structure, and the variation in the syntactic realizations of coherence relations can be characterized through an independently motivated interclausal relations hierarchy that governs the mapping between semantics and syntactic linkage (van Valin, 2005).

On the Nonexistence of Asymmetric DOM in Spanish

Kalin and Weisser (2019) observe that Spanish, among other differential-object-marking (DOM) languages, allows for what they call asymmetric DOM in coordination, that is, a DP coordinate structure in which an unmarked DP and a marked DP are conjoined. Given that coordinate structures are islands, asymmetric DOM challenges movement analyses for DOM. Yet we show that alleged cases of asymmetric DOM in Spanish do not involve DP-coordination; rather, they involve coordination of a larger structure plus TP-ellipsis. Evidence involves binding, extraction, fragment answers, and association with focus. We conclude that asymmetric DOM does not exist in Spanish, a fact consonant with movement analyses.

Oncogenic viruses, like viruses in general, can be divided into two classes, those that contain deoxyribonucleic acid (DNA) and those that contain ribonucleic acid (RNA). The RNA viruses have been recovered readily from the tumors which they cause whereas, the DNA-virus induced tumors have not yielded the virus. Since DNA viruses cannot be recovered, the bulk of present day investigations have been concerned with RNA viruses.The Lucké renal adenocarcinoma is a spontaneous tumor which occurs in northern leopard frogs (Rana pipiens) and has received increased attention in recent years because of its probable viral etiology. This hypothesis was first advanced by Lucké after he observed intranuclear inclusions in some of the tumor cells. Tumors with inclusions were examined at the fine structural level by Fawcett who showed that they contained immature and mature virus˗like particles.The use of this system in the study of oncogenic tumors offers several unique features, the virus has been shown to contain DNA and it can be recovered from the tumor, also, it is temperature sensitive. This latter feature is of importance because the virus can be transformed from a latent to a vegetative state by lowering or elevating the environmental temperature.

This article analyses the relationship between migrant entrepreneurship, marginalisation and social innovation. It does so, by looking how their ‘otherness’ is used on the one hand to reproduce their marginalised situation in society and on the other to develop new living and working arrangements promoting social innovation in society. The paper is based on a qualitative study, which was carried out from March 2014- 2016. In this period, twenty semi-structured interviews were conducted with migrant entrepreneurs and experts. As the results show, migrant entrepreneurs are characterised by a false dichotomy of “native weakness” in economic self-organisation against the “classical strength” of majority entrepreneurs. It is shown that new possibilities of acting in the context of migrant entrepreneurship are mostly organised in close relation to the lifeworlds and specific needs deriving from this sphere. Social innovation processes initiated by migrant entrepreneurs through their economic activities thus develop on a micro level and are hence less apparent. Supportive networks are missing on a structural level, so it becomes difficult for single innovative initiatives to be long-lasting.

This study aimed to identify the proportion of diversity and suitability of narrative mathematical questions with SOLO taxonomy level and mathematical power ability. The research was conducted through quantitative descriptive. Sources of data in the forms of narrations contained in mathematics textbooks. The research procedure was conducted by making the classification and determining the percentage of the narrations based on the compatibility of SOLO taxonomy and the mathematical power ability. The results showed that, the narrative mathematical questions with uni-structural level are of 7.5%, multi-structural of 33.8%, relational of 46.6% and extended abstract of 12.1 %. In terms of compatibility of the narrative  questions were able to measure 23% reasoning aspect, 18% problem solving, 8.3% connection, 28% communication and 22.6% mathematical representation. In general, mathematics textbooks as the object of research should be revised, since they have not yet achieved the ideal alignment between SOLO taxonomy based on grade level and the objective of learning develop mathematical power

AbstractDespite the immense importance of enzyme–substrate reactions, there is a lack of general and unbiased tools for identifying and prioritizing substrate proteins that are modified by the enzyme on the structural level. Here we describe a high-throughput unbiased proteomics method called System-wide Identification and prioritization of Enzyme Substrates by Thermal Analysis (SIESTA). The approach assumes that the enzymatic post-translational modification of substrate proteins is likely to change their thermal stability. In our proof-of-concept studies, SIESTA successfully identifies several known and novel substrate candidates for selenoprotein thioredoxin reductase 1, protein kinase B (AKT1) and poly-(ADP-ribose) polymerase-10 systems. Wider application of SIESTA can enhance our understanding of the role of enzymes in homeostasis and disease, opening opportunities to investigate the effect of post-translational modifications on signal transduction and facilitate drug discovery.
