On psychological growth and vulnerability: basic psychological need satisfaction and need frustration as an unifying principle

Humans have a potential for growth, integration, and well-being, while also being vulnerable to defensiveness, aggression, and ill-being. Self-determination theory (R. M. Ryan & E. L. Deci, 2000, Self-determination theory and the facilitation of intrinsic motivation, social development and well-being, American Psychologist, Vol. 55, pp. 68–78) argues that satisfaction of the basic psychological needs for autonomy, competence, and relatedness both fosters immediate well-being and strengthens inner resources contributing to subsequent resilience, whereas need frustration evokes ill-being and increased vulnerabilities for defensiveness and psychopathology. We briefly review recent research indicating how contextual need support and the experience of need satisfaction promote well-being and different growth manifestations (e.g., intrinsic motivation, internalization), as well as a rapidly growing body of work relating need thwarting and need frustration to ill-being, pursuit of need substitutes, and various forms of maladaptive functioning. Finally, we discuss research on differences in autonomous self-regulation and mindfulness, which serve as factors of resilience

A Multiplicative Model for Learning Distributed Text-Based Attribute Representations

In this paper we propose a general framework for learning distributed representations of attributes: characteristics of text whose representations can be jointly learned with word embeddings. Attributes can correspond to document indicators (to learn sentence vectors), language indicators (to learn distributed language representations), meta-data and side information (such as the age, gender and industry of a blogger) or representations of authors. We describe a third-order model where word context and attribute vectors interact multiplicatively to predict the next word in a sequence. This leads to the notion of conditional word similarity: how meanings of words change when conditioned on different attributes. We perform several experimental tasks including sentiment classification, cross-lingual document classification, and blog authorship attribution. We also qualitatively evaluate conditional word neighbours and attribute-conditioned text generation.Comment: 11 pages.

UK QE reconsidered: the real economy effects of monetary policy in the UK, 1990-2012 – an empirical analysis

Empirical studies of so called ‘unconventional’ monetary policy – ‘Quantitative Easing’ or ‘Large Scale Asset Purchases’ - since the North Atlantic Financial Crisis of 2007-2009 in the United Kingdom and elsewhere have mainly focussed on the effect of policy on intermediate variables rather than the stated ultimate goal of such policies, boosting nominal demand and GDP growth. Secondly and relatedly they tend to focus on the crisis and post-crisis period, a time of extraordinary economic and financial dislocation, which creates counterfactual and attribution problems and fails to capture typical macroeconomic lag dynamics. Adopting the approach of Voutsinas and Werner (2010), and building on Lyonnet and Werner’s (2012) study of UK QE, this paper addresses these weaknesses by 1) examining the impact of various different monetary policy instruments (including Quantitative Easing) directly on UK nominal GDP growth; and 2) using a quarterly time series beginning in the first quarter of 1990 and up to the last quarter of 2012 (92 observations in total). We use the Hendry ‘general-to-specific’ econometric methodology to estimate a parsimonious model. The results show that disaggregated bank credit to the real economy (households and firms) has the most significant impact on nominal GDP growth. Changes to the central bank’s interest rate, central bank reserves, and total central bank asset ratios drop out of the model as insignificant. The policy implication it that, as private banks continue to shrink their balance sheets in the UK and Europe following the North Atlantic Crisis of 2008, central banks might wish to consider ‘unconventional’ monetary policies that more directly boost credit to the real economy and thus nominal GDP growt
