How Do We Assess How Agentic We Are? A Literature Review of Existing Instruments to Evaluate and Measure Individuals' Agency

Social Indicators Research - The importance and centrality of the construct of agency is wellknown amongst social scientists. Yet, there is still little agreement on how this construct should be...     

Patterns of age‐based linguistic variation in American English1

In prior sociolinguistic research, speaker age has been considered the principal correlate of language change, but it ‘has not yet been explicitly studied as a sociolinguistic variable’ ( Eckert 1997 : 167). Consequently, little is known about how language varies across the life span. The present study employs key word analysis on a large corpus of casual conversation in American English to explore age‐based linguistic variation in spontaneous conversation. Analyses of the key words point to two major patterns of age‐based lexico‐grammatical variation: use of slang, and use of stance and involvement markers. Younger speakers' talk is characterized by an unusually frequent use of slang and swear words, and by a marked use of features indexing speaker's stance and emotional involvement, including intensifiers, stance adverbs, discourse markers, personal pronouns, and attitudinal adjectives; older speakers favor modals. These patterns are suggestive of functional differences in the discourse of youth and adults. It is argued that the expression of personal stance is more explicit and plays a key role in younger speakers' discourse.

A Generalized Bayes Rule for Prediction

In the case of prior knowledge about the unknown parameter, the Bayesian predictive density coincides with the Bayes estimator for the true density in the sense of the Kullback-Leibler divergence, but this is no longer true if we consider another loss function. In this paper we present a generalized Bayes rule to obtain Bayes density estimators with respect to any α-divergence, including the Kullback-Leibler divergence and the Hellinger distance. For curved exponential models, we study the asymptotic behaviour of these predictive densities. We show that, whatever prior we use, the generalized Bayes rule improves (in a non-Bayesian sense) the estimative density corresponding to a bias modification of the maximum likelihood estimator. It gives rise to a correspondence between choosing a prior density for the generalized Bayes rule and fixing a bias for the maximum likelihood estimator in the classical setting. A criterion for comparing and selecting prior densities is also given.     

Agro‐Food Preferences in the EU's GSP Scheme: An Analysis of Changes Between 2004 and 2006

This article examines the extent to which the 2006 revisions to the EU's Generalised System of Preferences improved market‐access opportunities for developing‐country agro‐food exports. It shows that they resulted in only a slight increase in the percentage preferential margin, but that there has been a significant increase in the value of preferential trade and of the preferential margin enjoyed by exporters. This was accompanied by changes in the ranking of beneficiaries. Countries such as China, Brazil, Argentina, India and South Africa maintained their significant shares of GSP agro‐food exports, but other countries such as Thailand and Vietnam have now emerged as major GSP beneficiaries.     

Diffracting the rays of technoscience: a situated critique of representation

This essay focuses on the possibility of adopting a representational approach for technoscience, in which representation is considered as a situated process of dynamic "intra-action" (Barad 2007). Re-elaborating the recent critiques of representationalism (Thrift 2008), my analysis begins by analysing Hayles's situated model of representation from an early essay where she explains her definition of constrained constructivism (Hayles [1991] 1997). The essay then discusses the notions of figuration and diffraction and the way they are employed by Haraway in many of her writings for her critique of technoscience (Haraway 1991, 1997). Finally, after considering diffraction through Barad's reading of this practice in the context of her theory of agential realism (2007), it shows the links that relate constrained constructivism, situated knowledge and agential realism, and the way all of them work at "diffract[ing] the rays of technoscience" (Haraway 1997: 16) through an alternative representational practice.     

A Systems View of Companies’ Communication in Online Social Environments

In order to enrich previous contributions interested in the identification of possible pathways to improve companies’ capabilities to better face the challenges imposed by increasing social and economic variety, this paper focuses attention on the role of companies’ communications in online social environments. Thanks to the adoption of systems thinking, the paper enlarges existing contributions on companies’ online communication by combining the research streams of signalling theory, capital need theory, and legitimacy theory. By building on a multi-disciplinary literature review, this paper identifies three variables to analyse the effectiveness of companies’ communication based on the use of social networks: the frequency, the instability, and the previous activities. Empirical research is proposed with reference to a sample composed by the 50 best performing European companies in terms of return on sales (ROS) (USD) in 2015 via the use of structural equation modelling (SEM). SEM is applied to explore the relationships among identified variables in companies’ online communication on Facebook and Instagram, and how those communications influence companies’ economic performance in terms of ROS.     

Effects of placentophagy on maternal salivary hormones: A pilot trial,part 1

Background

Recent studies show that human placenta, processed and encapsulated for postpartum consumption, contains a host of trace minerals and hormones that could conceivably affect maternal physiology. Our objective was to investigate whether salivary hormone concentrations of women ingesting their own encapsulated placenta during the early postpartum differed from those of women consuming a placebo.

Citalopram-Associated Gambling: A Case Report

Pathological gambling behaviour is a side effect of dopaminergic drugs used in Parkinson’s disease, but has seldom been reported with selective serotonin reuptake inhibitors. A 58-years-old woman with somatisation disorder since the age of 20 and recent-onset major depression (at 54 years) received 40 mg/day intravenous citalopram, thereafter switching to the same dose of oral citalopram to treat her comorbid psychiatric disorders after showing poor response to paroxetine for one year. Her anxious and depressive symptoms were moderately reduced after 7 months of oral citalopram, but simultaneously, the patient admitted gambling. We gradually discontinued citalopram and introduced pregabalin and alprazolam; this was followed by a reduction of gambling compulsions, but the somatisation and depressive symptoms did not further improve. Pathological gambling may be mediated by an interplay of 5-HT_1A serotonergic and D₂ dopaminergic mechanisms. Citalopram affects both these mechanisms in areas that were shown to be involved in gambling behaviour, but while dopaminergic effects of citalopram appear to be consistent with the induction of gambling, its serotonergic mechanisms are rather inconsistent. In our patient, mood destabilisation induced by citalopram may have contributed to the first onset of pathological gambling.     

A note about calibrated prediction regions and distributions

In this work we address the problem of the construction of prediction regions and distribution functions, with particular regard to the multidimensional setting. Firstly, we define a simple procedure for calculating the predictive distribution function which gives improved prediction limits. Secondly, with a multivariate generalization of a result presented in Ueki and Fueda (2007), we propose a method for correcting estimative prediction regions, to reduce their coverage error to the third-order accuracy. The improved prediction regions and the associated distribution functions are easy to calculate using a suitable bootstrap procedure. Examples of application are included, showing the good performance of the proposed method, even if we consider an approximated model for prediction purposes.
