Major Depressive Disorder (MDD) is often associated with high levels of stress and disturbances in the Hypothalamic Pituitary Adrenal (HPA) system, yielding high levels of cortisol, in addition to cognitive dysfunction. Previous studies have shown a relationship between cortisol profile and cognitive functioning in recurrent MDD in general. More specifically, the association between hypercortisolism and cognitive functioning, such as memory and Executive Functioning (EF), and also more recently cortisol suppression has been explored. However, no studies have investigated these relationships in patients diagnosed with first episode MDD. The aim of the present study was to examine the relationship between cortisol levels before and after the Dexamethasone suppression test (DST) and cognitive function in first episode MDD patients. Twenty‐one patients meeting the DSM‐IV criteria for a first episode of MDD diagnosis were included in the study. The control group was matched for age, gender and education level. Cortisol was measured in saliva collected with Salivette sampling devices. Saliva samples were collected 4 times during a 24 hours period over two consecutive days: at awakening, after 45 minutes, after 7 hours and at 11 pm. Dexamethasone (1.0 mg) was given orally on Day 1 at 11 pm. The neuropsychological test battery consisted of standardized tests measuring executive functioning (EF) and memory functioning. Cortisol levels did not differ significantly between patients and controls on Day 1, except for the last sample before Dexamethasone administration, where the control group showed higher levels. Both groups showed suppression after Dexamethasone. On Day 2 there was a significant difference between groups at the third sample, showing a significantly lower level in the control group, suggesting that the controls have a more effective suppression profile than the patients. There were no significant correlations between cortisol levels before or after Dexamethasone and cognitive measures. The results indicate impairment on HPA‐axis functioning in first episode MDD patients, with less suppression functioning compared to healthy controls, but no relationship between cortisol profile and cognitive functioning in EF or Memory. 相似文献

Eradication is a radical form of contraction that removes not only a sentence but also all of its non-tautological consequences from a belief set. Eradication of a single sentence that was included in the original belief set coincides with full meet contraction, but if the sentence is external to the belief set then the two operations differ. Multiple eradication, i.e. simultaneous eradication of several sentences, differs from full meet contraction even if the sentences to be contracted are all included in the original belief set. Eradication is axiomatically characterized and its properties investigated. It is shown to have close connections with the recovery postulate for multiple contraction. Based on these connections it is proposed that eradication rather than full meet contraction is the appropriate lower limiting case for multiple contraction operators. 相似文献

Humanitarian aid professionals frequently encounter situations in which one is conscious of the morally appropriate action but cannot take it because of institutional obstacles. Dilemmas like this are likely to result in a specific kind of stress reaction at the individual level, labeled as moral stress. In our study, 16 individuals working with international humanitarian aid and rescue operations participated in semistructured interviews, analyzed in accordance with a grounded theory approach. A theoretical model of ethical decision making from a moral stress perspective was developed. The practical implications of the study are discussed. 相似文献

We can often specify how we would contract by a certain sentence by saying that this contraction would coincide with some other contraction that we know how to perform. We can for instance clarify that our contraction by p&q would coincide with our contraction by p, or by q, or by {p, q}. In a framework where the set of potential outcomes is known, some contractions are “self-evident” in the sense that there is only one serious candidate that can be the outcome of such a contraction. Contraction by a specific contractee (sentence or set of sentences to be contracted) is bootstrapped if it is specified by saying that it coincides with some such self-evident contraction. For a wide range of (multiple) contraction operators, contractions by any contractee can be bootstrapped. This means that the selection mechanism (selection function, incision function, etc.) can be replaced by a function called a bootstrapping selector that assigns to each contractee some “self-evident” contractee that yields the same outcome. With bootstrapping we can eliminate traditional extralogical components in contraction (e.g., selection functions) and replace them by bootstrapping selectors that reflect more closely the ways in which we actually reason and argue about belief contraction. 相似文献

Abstract : Phil Zuckerman argues in his book Society without God that Scandinavian secularity is strongly correlated to Scandinavian prosperity. In this article, we argue that such usage is premature. First, there are methodological issues that are not properly dealt with. Second, providing a causal narrative in addition to mere correlation is needed. Third, we argue that the causes of Scandinavian prosperity are found in close connection to Scandinavian Lutheranism. 相似文献

Increasing evidence suggests a role of the immune system in modulation of cognition, but details on affected memory systems are largely lacking. We therefore aimed to study the relation between selected cytokines and subsets of memory, and the impact of age in these relations. From a random population-based sample (the Betula Prospective Cohort Study), 298 women (age 45-90) were studied in terms of episodic recall and recognition, semantic fluency and knowledge, and prospective memory. Circulating cytokines of relevance for cognition and aging were measured with ELISA. Levels of interleukin (IL)-6 and sIL-2R were significantly and negatively associated with most cognitive variables, while the opposite was true for IL-1β. Age shared substantial variance with both cytokines and memory, and turned most correlations non-significant when controlled for together with education, BMI and presence of disease. Interactions between age and cytokines were further analyzed in multiple regressions. For IL-6, significant negative interactions with age were found for semantic fluency (p<0.05) and prospective memory (p<0.01), and for sIL-2R in predicting semantic knowledge (p<0.05), indicating an increased negative impact of these cytokines on memory with increasing age. In conclusion, the study indicates a relation between cytokines and memory that appears to be largely mediated by age, and supports the suggestion that cytokine dysregulation with higher age may interact with cognitive aging. 相似文献

The Church of Sweden was democratized in the 1930s when party politics was introduced into church elections. Since then, party politics have more and more been part of the governing style of the Church of Sweden. In 2000 the church was disestablished and a new election system was introduced with direct elections to the General Synod. The system of political parties remained. This article questions the democracy of the church using criteria for democratic structures. It also focuses on the role of the ordained ministry in the governance of the church, as the bishops have not been full members of the Synod since 1982. The conclusions are that the Church of Sweden is not fully democratic since participation in elections is at about 10% and the electorate has few chances to understand what the elections are about. The bishops’ weak formal position in the Synod is not in accordance with the teachings of the church on episcopacy. The conflict between democratic principles, inherited from the Swedish constitution, and church teaching on the ordained ministry and its role has not been fully resolved so far. 相似文献

The ideal world semantics of standard deontic logic identifies our obligations with how we would act in an ideal world. However,
to act as if one lived in an ideal world is bad moral advice, associated with wishful thinking rather than well-considered
moral deliberation. Ideal world semantics gives rise to implausible logical principles, and the metaphysical arguments that
have been put forward in its favour turn out to be based on a too limited view of truth-functional representation. It is argued
that ideal world semantics should be given up in favour of other, more plausible uses of possible worlds for modelling normative
subject-matter. 相似文献
