Longitudinal associations between causal sexual relationships and stressful life events in emerging adults

Findings on the consequences of casual sexual relationships (CSR) are inconsistent and range from positive to negative outcomes. The longitudinal association between stressful live events and CSR was investigated in a random sample of 2844 Swiss emerging adults. Cross-lagged panel models with baseline, two- and five-year follow-up data showed that life events predicted more subsequent CSR across emerging adulthood. In contrast, CSR predicted life events only from the first to the second wave. Results suggest that the link between stressful life events and CSR was mainly explained by romantic breakups as stressful life event. Environment-related life events were not substantially associated with casual sexual relationships. Thus, engaging in CSR did not seem to be a general emotion-focused coping strategy in the context of life events nor can the engagement in casual sex be seen as a result of stressful life events affecting general self-regulation.

Topology of the ambient boundary and the convergence of causal curves

We discuss the topological nature of the boundary spacetime, the conformal infinity of the ambient cosmological metric. Due to the existence of a homothetic group, the bounding spacetime must be equipped not with the usual Euclidean metric topology but with the Zeeman fine topology. This then places severe constraints to the convergence of a sequence of causal curves and the extraction of a limit curve, and also to our ability to formulate conditions for singularity formation.

Quantifying the improvement in sepsis diagnosis, documentation, and coding: the marginal causal effect of year of hospitalization on sepsis diagnosis.

PURPOSE To quantify the coinciding improvement in the clinical diagnosis of sepsis, its documentation in the electronic health records, and subsequent medical coding of sepsis for billing purposes in recent years. METHODS We examined 98,267 hospitalizations in 66,208 patients who met systemic inflammatory response syndrome criteria at a tertiary care center from 2008 to 2012. We used g-computation to estimate the causal effect of the year of hospitalization on receiving an International Classification of Diseases, Ninth Revision, Clinical Modification discharge diagnosis code for sepsis by estimating changes in the probability of getting diagnosed and coded for sepsis during the study period. RESULTS When adjusted for demographics, Charlson-Deyo comorbidity index, blood culture frequency per hospitalization, and intensive care unit admission, the causal risk difference for receiving a discharge code for sepsis per 100 hospitalizations with systemic inflammatory response syndrome, had the hospitalization occurred in 2012, was estimated to be 3.9% (95% confidence interval [CI], 3.8%-4.0%), 3.4% (95% CI, 3.3%-3.5%), 2.2% (95% CI, 2.1%-2.3%), and 0.9% (95% CI, 0.8%-1.1%) from 2008 to 2011, respectively. CONCLUSIONS Patients with similar characteristics and risk factors had a higher of probability of getting diagnosed, documented, and coded for sepsis in 2012 than in previous years, which contributed to an apparent increase in sepsis incidence.

English and French causal connectives in contrast

Discourse connectives are often said to be language specific, and therefore not easily paired with a translation equivalent in a target language. However, few studies have assessed the magnitude and the causes of these divergences. In this paper, we provide an overview of the similarities and discrepancies between causal connectives in two typologically related languages: English and French. We first discuss two criteria used in the literature to account for these differences: the notion of domains of use and the information status of the cause segment. We then test the validity of these criteria through an empirical contrastive study of causal connectives in English and French, performed on a bidirectional corpus. Our results indicate that French and English connectives have only partially overlapping profiles and that translation equivalents are adequately predicted by these two criteria.

Car, parce que, puisque’ revisited: Three empirical studies on French causal connectives

In French, a causal relation is often conveyed by the connectives car, parce que or puisque. Since the seminal work of the Lambda-l Group (1975), it has generally been assumed that parce que, used to relate semantic content, contrasts with car and puisque, both used to connect either speech act or epistemic content. However, this analysis leaves a number of questions unanswered. In this paper, I present a reanalysis of this trio, using empirical methods such as corpus analysis and constrained elicitation. Results indicate that car and parce que are interchangeable in many contexts, even if they are still prototypically used in their respective domain in writing. As for puisque, its distribution does not overlap with car, despite their similar domains of use. I argue that the specificity of puisque with respect to the other two connectives is to introduce a cause with an echoic meaning.

Expanding Our Grasp: Causal Knowledge and the Problem of Unconceived Alternatives

I argue that scientific realism, insofar as it is only committed to those scientific posits of which we have causal knowledge, is immune to Kyle Stanford’s argument from unconceived alternatives. This causal strategy (previously introduced, but not worked out in detail, by Anjan Chakravartty) is shown not to repeat the shortcomings of previous realist responses to Stanford’s argument. Furthermore, I show that the notion of causal knowledge underlying it can be made sufficiently precise by means of conceptual tools recently introduced into the debate on scientific realism. Finally, I apply this strategy to the case of Jean Perrin’s experimental work on the atomic hypothesis, disputing Stanford’s claim that the problem of unconceived alternatives invalidates a realist interpretation of this historical episode.
