We show that if an agent reasons according to standard inference rules, the truth and introspection axioms extend from the set of non-epistemic propositions to the whole set of propositions. This implies that the usual axiomatization of partitional possibility correspondences is redundant, and provides a justification for truth and introspection that is partly based on reasoning.  相似文献

Despite proliferation of political protest by migrants in recent years, analyses from a social movement perspective remain scarce. This lacuna is not coincidental, but theoretically grounded. According to dominant movement theories, migrants are unlikely subjects of mobilization due to legal obstacles, scarce resources and closed political and discursive opportunities. The article therefore explores how marginalized migrants organize transnational political protest against all evident odds. Drawing from extensive fieldwork and bridging transnational migration and social movement studies, it is argued that migrants mobilize within transnational social spaces, which link relations and emotions acquired on the move with the relational qualities at the locality of arrival. The article illustrates how the transnational spaces most migrants inhabit can be politicized and transformed into particular social formations, for which the term ‘transnational contentious spaces’ is suggested.  相似文献

Background

Oxytocin is the most widely used drug in the induction of labor, but it could have potential adverse effects that derive from uterine hyperstimulation.

Aim

To determine the benefits and drawbacks of oxytocin continuation versus oxytocin discontinuation after the active phase of induced labor.

Methods

We systematically searched Pubmed, EMBASE, Scopus, ClinicalTrials.gov and Cochrane Library Plus until October 2017, for randomized controlled trials comparing oxytocin continuation with oxytocin discontinuation when the active phase of labor is reached were included. Data was collected by three reviewers and quality of the included studies assessed using the methodology recommended in the Cochrane Handbook. StatsDirect software was used to calculate risk ratios for binary variables and weighted mean differences for continuous variables. A fixed-effects or random-effects model was used as appropriate.

Results

Nine studies were selected including 1538 women, 774 in the oxytocin continuation group and 764 in the oxytocin discontinuation group. The incidence of cesarean sections (14.3% vs. 8.6%; relative risk, 1.67; 95% confidence interval: 1.25–2.23), uterine hyperstimulation (12.4% vs. 4.7%; relative risk, 2.59; 95% confidence interval: 1.70–3.93) and nonreassuring fetal heart rate (19.2% vs.12.5%; relative risk, 1.55; 95% confidence interval: 1.18–2.02) were significantly higher in the oxytocin continuation group. An increase in the duration of the second stage of labor in the oxytocin discontinuation group was observed (pooled mean difference, ?7.03; 95% confidence interval: ?9.80 to ?4.26).

Conclusions

After the active phase of induced labor, oxytocin continuation increases the risk of cesarean section, uterine hyperstimulation and alterations to the fetal heart rate.  相似文献

Focussing on the inclusion of those primarily affected as stakeholders (refugees and other migrants), this article addresses a key ambition of the compacts themselves. We employ an ‘inside‐outside’ perspective and firstly ask: which groups participated in the consultative processes, what agenda did they set ‘inside’ the meetings, what alliances did they establish and how did they influence the outcomes? Secondly, we investigate what kind of advocacy took place ‘outside’ of these formalized spaces and what impact it had? By this, we not only contribute to an evaluation of the processes themselves, but also advance current academic debates on strategies, spaces and political opportunity structures for civil society and particularly migrant involvement in global migration governance from below and the larger debate on democratizing global institutions.  相似文献

Abstract

Feminist studies of political economy have long pointed to the multifaceted ways in which global transformations are constituted by deeply gendered economic practices at the everyday level. Nonetheless, the increased analytical focus on the everyday within the study of international political economy (IPE) frequently fails to connect with feminist theories and gendered approaches. In this introductory essay, we argue that any discussion of a ‘turn’ towards the everyday in IPE must acknowledge the role of feminist contributions that predate, and indeed make possible, this shift in IPE scholarship's analytical gaze towards the everyday. We map out what might be understood as feminist political economies of the everyday—highlighting the points of connection between feminist scholarship on the everyday, as well as the ways in which feminist scholars engage with the notion of an everyday political economy in quite distinct and diverse ways—a diversity that reflects the methodological and theoretical pluralism of feminist political economy scholarship as well as the ever broadening geographical scope of feminist research.  相似文献

Background

The participation of master cross-country (XC) skiers in training and competition has increased during the last decades; however, little is known yet about whether these athletes differ from their younger counterparts in aspects of performance such as pacing. Therefore, the aim of the present study was to examine the combined effect of age and performance (race time) on pacing in cross-country (XC) skiing. We analyzed all finishers (n?=?79,722) in ‘Vasaloppet’ from 2012 to 2017, the largest cross-country skiing race in the world, classified according to their race time into 10 groups: 3-4 h, 4-5 h, ..., 12-13 h.

Results

A trivial main effect of sex on total pace range was observed (p?<?0.001, η2?=?0.002), where women (44.1?±?10.2%) had larger total pace range than men (40.9?±?11.8%). A large main effect of performance group on total pace range was shown (p?<?0.001, η2?=?0.160), where the smallest total pace range was 21.8?±?1.9% (3-4 h group) and the largest 50.1?±?9.9% (10-11 h group). A trivial sex×performance group interaction on total pace range was found (p?<?0.001, η2?=?0.001) with the largest sex difference in pacing shown in 9-10 h group. A trivial and small main effect of age was found in women (p?<?0.001, η2?=?0.005) and men (p?<?0.001, η2?=?0.011), respectively, where the masters had smaller total pace range than their younger counterparts. A trivial age group×performance group interaction on total pace range was observed in both women (p?<?0.001, η2?=?0.008) and men (p?<?0.001, η2?=?0.006) with smaller differences among age groups in the faster performance groups.

Conclusions

In summary, master XC skiers adopted a relatively even pacing independently from their race time and the differences in pacing from the younger XC skiers were more pronounced in the slower masters. These findings suggest that exercise attenuates the decline of performance in master XC skiers as shown by the similar pacing strategies between fast master XC skiers and their younger counterparts.

The authors propose a family of robust nonparametric estimators for regression or autoregression functions based on kernel methods. They show the strong uniform consistency of these estimators under a general ergodicity condition when the data are unbounded and range over suitably increasing sequences of compact sets. They give some implications of these results for stating the prediction in Markovian processes with finite order and show, through simulation, the efficiency of the predictors they propose.  相似文献

The purpose of the current study was to assess whether individuals with intellectual disabilities would emit untrained speaker responses (i.e., signed tacts and mands) after being taught listener behaviors. Listener relations were trained via an automated matching-to-sample (MTS) procedure. Following mastery, the emergence of signed tacts, generalized tacts, and mands was tested. All participants met criterion in listener relations training and showed the emergence of almost all relations. Results suggest that teaching listener relations first, through MTS tasks, is a viable way to produce emergence of speaker relations.  相似文献
