The purpose of this paper is to argue that the tactic of granting a fetus the legal status of a person will not, contrary to the expectations of opponents of abortion, provide grounds for a general prohibition on abortions. I begin by examining two arguments, one moral (J. J. Thomson's 'A Defense of Abortion') and the other legal (D. Regan's 'Rewriting Roe v. Wade'), which grant the assumption ...

Conventional techniques for combating phishing have focused primarily on detecting phishing web sites and preventing users from revealing their passwords to such sites. This passive form of defense is by its nature incomplete and does nothing to protect users that do reveal their passwords. Combating the phishing threat requires more than simple avoidance—it requires a more active approach to d...

On October 18, 2003, the Defense Meteorological Satellite Program (DMSP) successfully launched DMSP F16 satellite with the first Special Sensor Microwave Imager Sounder (SSMI/S) instrument aboard. The SSMI/S is a conically-scanning passive microwave radiometer that includes seven temperature-sounding channels peaking below 30 km (channels 1-7), and six peaking between 30 km and 80 km (channels ...

the occurrence of natural and human disasters can create heavy casualties in cities and urban areas and such a critical issue makes it inevitable to pay a great deal of attention to the vulnerability and safety aspects of cities and the accessibility to the urban welfare standards from the perspective of passive defense. the geostrategic location of koohdasht city in iran and its vulnerability ...

Automatic defense responses promote survival and appropriate action under threat. They have also been associated with the development of threat-related psychiatric syndromes. Targeting such automatic responses during threat may be useful in populations with frequent threat exposure. Here, two experiments explored whether mental imagery as a pre-trauma manipulation could influence fear bradycard...

The popularity of reactive worms, whose attacking behavior inherits characteristics from both active worms and passive worms, has brought great threat to P2P networks in recent years. Most existing defense models only focus on the effects of P2P churn on reactive worm's propagation, but neglect the impact of user behaviors on the spread of worms. This paper proposes a defense model of reactive ...

Inking by marine molluscs such as sea hares, cuttlefish, squid, and octopuses is a striking behavior that is ideal for neuroecological explorations. While inking is generally thought to be used in active defense against predators, experimental evidence for this view is either scant or lacks mechanistic explanations. Does ink act through the visual or chemical modality? If inking is a chemical d...

Background Allergy is an increasing autoimmune disease in the developed world. Current consensus is that allergy is the result of a misdirected immune response directed towards ‘seemingly innocuous antigens’. Many of the allergens have similarities with parasite proteins and it is generally accepted that the IgE (Immunoglobulin E) response is a normal defense mechanism against parasitic infesta...

Dynamic response of underground structures has always been a topic of concern for designers and researchers. The behavior of these complicated systems under blast loading is affected by various factors and parametric studies are required to investigate their significance. The importance of soil density around the underground structure through which, the waves of explosion of a penetrator bomb i...
