Information and anti-terrorist security of Poland. A critical analysis exemplified with the tasks and activity of the Internal Security Agency

The subject matter of the analysis conducted in the text is information and anti-terrorist security of Poland, which has been presented within the context of a clash between two spheres – the state and the private sphere. Furthermore, the issues of security have been supplemented with a description of the tasks and activity of the Internal Security Agency, as well as a synthetic appraisal of a terrorist threat to Poland. The main parts of this work are concerned with: (1) the state and the private sphere, (2) " terrorism " and terrorist offences, (3) the tasks and activity of the Internal Security Agency, (4) an appraisal of a terrorist threat to Poland. Given the necessity to elaborate the research problem, the text features the following research questions: (1) To what extent does referring to a threat to security influence a limitation on rights and freedoms in Poland (with regard to the clash between the state and the private sphere)?, (2) To what extent do the tasks and activity of the Internal Security Agency influence the effectiveness of anti-terrorist security in Poland?

Rediscovering the King of Woodpeckers: Exploring the Implications

The Ivory-billed Woodpecker has long held a special place in the psyche of North American conservation, eliciting unusually colorful prose, even from scientists, as an icon of the wild. The reverence in which it was held did little to slow the habitat loss that led to its apparent extinction 60 years ago. A consequence of the emotion and attention associated with the amazing rediscovery of this species is that conservation biologists will be under considerable pressure to make good on this “second chance.” This poses a challenge to conservation paradigms that has important political consequences. First, the decline of the species is due to habitat loss, recovery from which has been much more seldom achieved than recovery from declines due to impacts on vital rates. This challenge is exacerbated by the enormous area requirements of the species. Second, the species at best exists as a critically small population. It will be difficult to make the case that a viable population can be established without undermining the small population paradigm that underlies conservation strategies for many other species. This has already resulted in some political backlash. Conservation of this species is best based on the one point of clear scientific consensus, that habitat is limiting, but this may result in additional political backlash because of conflicts with other land uses.

EspJ is a prophage-carried type III effector protein of attaching and effacing pathogens that modulates infection dynamics

Enterohemorrhagic Escherichia coli, enteropathogenic E. coli, and Citrobacter rodentium are highly adapted enteropathogens that successfully colonize their host's gastrointestinal tract via the formation of attaching and effacing (A/E) lesions. These pathogens utilize a type III secretion system (TTSS) apparatus, encoded by the locus of enterocyte effacement, to translocate bacterial effector proteins into epithelial cells. Here, we report the identification of EspJ (E. coli-secreted protein J), a translocated TTSS effector that is carried on the 5' end of the cryptic prophage CP-933U. Infection of epithelial cells in culture revealed that EspJ is not required for A/E lesion activity in vivo and ex vivo. However, in vivo studies performed with mice demonstrated that EspJ possesses properties that influence the dynamics of clearance of the pathogen from the host's intestinal tract, suggesting a role in host survival and pathogen transmission.

Mercury(II) and thallium(III) organometallic derivatives of 2-Mercaptobenzoxazole

Some derivatives of 2-mercaptobenzoxazole (HL) of the type MRnL [M = Hg or Tl, R = Me or Ph and n = 1 (Hg) or 2 (Tl)] have been prepared. The structure of HgMeL has been determined by an X-ray diffraction study; in the crystal there are two independent planar molecules in each asymmetric unit, with the ligand in its thiolic form and an almost linear CHgS linkage. Weak intramolecular and intermolecular secondary interactions complement the mercurysulphur bond. The spectroscopic (IR, Raman, mass, 13C-NMR), conductimetric, and dipolar properties of this and the other compounds are discussed. © 1991.
