Copular Complements: Closed or Open?

In this paper, we present some preliminary observations on the syntactic analysis of copular constructions in LFG. We suggest several conclusions and directions for future research. First, the open analysis is appropriate for some copular constructions but not for others, even within the same language. Second, the same construction can be open in some languages and closed in others. Third, we c...

Firms as Incubators of Open-Source Software

Many successful open source projects have been developed by programmers who were employed by firms but worked on the open source projects on the side due to economic incentives like career improvement benefits. Such side work may be a good thing for the employing firms too if they get some strategic value from the open source software and/ or if the productivity of the programmers on these proj...

Intensive Care Units: Open or Closed?

Mitosis, not just open or closed.

During cell division, eukaryotic cells must faithfully pass on their genetic material to the next generation during mitosis. It has long been known that lower eukaryotes and higher eukaryotes achieve this in strikingly different ways. Higher eukaryotes undergo an open mitosis in which the nuclear envelope is completely disassembled at the G2/M transition and is not reassembled until after DNA s...

An open or closed case for HMGA

An open or closed case for HMGA S enescence turns a chromatin-activating protein towards the dark side. Upon senescence induction, high mobility group A (HMGA) protein helps to make silent heterochromatin, report Masashi Narita, Scott Lowe, and colleagues (Cold Spring Harbor Laboratory, NY). HMGA proteins promote open and active chromatin, are highly expressed in the early embryo, and can promo...
