What is a Logic

Abstract: This paper builds on the theory of institutions, a version of abstract model theory that emerged in computer science studies of software specification and semantics. To handle proof theory, our institutions use an extension of traditional categorical logic with sets of sentences as objects instead of single sentences, and with morphisms representing proofs as usual. A natural equivalence relation on institutions is defined such that its equivalence classes are logics. Several invariants are defined for this equivalence, including a Lindenbaum algebra construction, its generalization to a Lindenbaum category construction that includes proofs, and model cardinality spectra; these are used in some examples to show logics inequivalent. Generalizations of familiar results from first order to arbitrary logics are also discussed, including Craig interpolation and Beth definability.

An institutional theory of the informal economy: some lessons from the United Kingdom

Abstract: Purpose – The purpose of this paper is to propose a new way of explaining participation in the informal economy as resulting from the asymmetry between the codified laws and regulations of a society’s formal institutions (government morality) and the norms, values and beliefs of the population that constitute its informal institutions (societal morality). The proposition is that the greater the asymmetry between government morality and societal morality, the greater is the propensity to participate in the informal economy. Design/methodology/approach – To evaluate this institutional asymmetry theory, the results are reported of 1,306 face-to-face interviews conducted during 2013 in the UK. Findings – The finding is a strong correlation between the degree of institutional asymmetry (measured by tax morale) and participation in the informal economy. The lower the tax morale, the greater is the propensity to participate in the informal economy. Using ordered logistic regression analysis, tax morale is not fo...

Violence against women by male partners and against children within the family: prevalence, associated factors, and intergenerational transmission in Romania, a cross-sectional study

Abstract: Domestic violence is a public health problem with negative consequences. We aimed to determine the prevalence of violence between parents and by parents against children, types of intimate partner violence against women, the intergenerational transmission of violence, and to identify a profile of beliefs and judgements regarding violent behaviour. The data used for this article were sourced from three cross-sectional studies performed in Romania in 2009–2011. We sampled 869 respondents (male and female) with a homogenous distribution between environment, gender, educational level, and age group (18 to 75). From a 96-item questionnaire regarding family and reproductive health, this article refers to four items: (1) feelings relating to the family in which they were raised; (2) whether they witnessed violence between parents or were victims of violence by parents or other family members during childhood or the teenage years; (3) opinions relating to 10 statements on violence from Maudsley Violence Questionnaire; (4) the manifestation of psychological, emotional, and sexual abuse from the partner in the family of procreation (FOP). The data were analysed by Pearson chi-square tests and latent class analysis. During childhood, 35% of respondents witnessed parental violence and 53.7% were victims of family violence. Psychological abuse by men against women was the most common type of violence reported in the FOP (45.1%). Violence in childhood and adolescence correlated with the perception of the family of origin as a hostile environment and of violence against women as a corrective measure, and that insults, swearing, and humiliation by their partner within the FOP is acceptable (p < 0.05). A profile of beliefs and judgements about violent behaviour indicated that the Impulsive reactive cluster is represented by men in rural areas, and by subjects who witnessed parental violence or were victims of violence during childhood (p < 0.001). In Romania, the use of violence as a form of discipline or instruction of children and women remains a significant problem, with a higher rate of intimate partner violence than in other developed countries. Furthermore, implementing intervention mechanisms for psychological abuse is urgently required, as are education and intervention in high-risk populations.
