Matching of concepts against patterns is a new inference task in Description Logics, which was originally motivated by applications of the Classic system. Consequently, the work on this problem was until now mostly concerned with sublanguages of the Classic language, which does not allow for existential restrictions. Motivated by an application in chemical process engineering, which requires a ...

Logotherapy is a meaning-centered p.ychotherapy which focuses on both the meaning of iiuman existence and the personal search for meaning. If the w_11 to search for meaning is frustrated, "existential frustration" may result. This study validates the Existential Anxiety Scale (EAS) developed by Good and Good (1974). Basic principles of logotherapy are discussed and related research is reviewed....

BACKGROUND The experiences of people with cancer and organ disease have been described across different dimensions of need as they approach death. Such information is lacking for frail older people approaching death, but could highlight how a palliative approach might be relevant for this population. METHODS Cognitively intact, community dwelling adults considered to be moderately or severely...

We give the complete picture of the complexity of conjunctive query answering under (weakly-)(frontier-)guarded disjunctive existential rules, i.e., existential rules extended with disjunction, and their main subclasses, linear rules and inclusion dependencies.

Well, it ’s finally happened. I’ve been attacked in the scientific literature ~Salander, 2006!. Well, just to clarify, it wasn’t a personal attack, but rather an attack of the highest and most noble order: an attack on the scientific rigor of the conceptual underpinnings of my recent work on meaning and spirituality in advanced cancer patients ~e.g., Breitbart, 2002!. To be honest, and a bit le...

When a person is diagnosed with a severe disease, it seems plausible that existential questions and death anxiety are easily intensified. The aims of this study were to explore whether this is the case, to what extent patients and their next of kin experience death anxiety, and how these experiences are expressed. Following a purposive sampling technique, 20 patients with brain tumours and 15 o...

A prominent existential concept is that elderly parents should naturally become severely ill or die before a younger person does. If the reverse should happen, it may influence the parent's existential view of life. The aim of this study was to investigate the existential issues during illness time. This was a qualitative study with in-depth interviews and was conducted in a University Hospital...

Existential threat lies at the heart of intergroup conflict, but the literature on existential concerns lacks clear conceptualization and integration. To address this problem, we offer a new conceptualization and measurement of existential threat. We establish the reliability and validity of our measure, and to illustrate its utility, we examine whether different existential threats underlie th...
