General Theory: Topological Aspects
2009
In Chapter 1, we have analyzed the structure of pip-spaces from the algebraic point of view only, (i.e., the compatibility relation). Here we will discuss primarily the topological structure given by the partial inner product itself. The aim is to tighten the definitions so as to eliminate as many pathologies as possible. The picture that emerges is reassuringly simple: Only two types of pip-spaces seem sufficiently regular to have any practical use, namely lattices of Hilbert spaces (LHS) or Banach spaces (LBS), that we have introduced briefly in the Introduction. Our standard reference on locally convex topological vector spaces (LCS) will be the textbook of Kothe [Kot69]. In addition, fo…
Using VIS/NIR and IR spectral cameras for detecting and separating crime scene details
2012
Detecting invisible details and separating mixed evidence is critical for forensic inspection. If this can be done reliably and fast at the crime scene, irrelevant objects do not require further examination at the laboratory. This will speed up the inspection process and release resources for other critical tasks. This article reports on tests which have been carried out at the University of Jyväskylä in Finland together with the Central Finland Police Department and the National Bureau of Investigation for detecting and separating forensic details with hyperspectral technology. In the tests evidence was sought after at an assumed violent burglary scene with the use of VTT's 500-900 nm wave…
Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
2022
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of …
Sosiaalinen pääoma ja yksilötason tulokehitys Suomessa
2018
Tässä tutkimuksessa tarkastelemme yksilön sosiaalisista verkostoista muodostuvan sosiaalisen pääoman yhteyttä yksilötason tulokehitykseen. Analyysimme perustuvat vuoden 1986 elinolotutkimukseen osallistuneisiin 20–44 vuotiaisiin työllisiin ja rekisteritietoihin heidän palkkatuloistaan vuosilta 1987–1997. Tutkimuksessa erottelemme toisistaan sitovan ja silloittavan sosiaalisen pääoman muodot. Sitovan sosiaalisen pääoman mittarimme perustuu yksilön mahdollisuuteen saada apua verkostoistaan erilaisissa arkielämän tilanteissa. Silloittavaa sosiaalista pääomaa mittasimme yksilöiden yhdistysjäsenyyksien monipuolisuuden kautta. Analyysit suoritettiin paloittain jatkuvalla linea…
