Conceptualizing and Measuring Financial Resilience: A Multidimensional Framework

Financial inclusion has become a policy priority. For many countries, this has meant focusing on the delivery and practical aspects of financial products and services. This paper argues that this approach is not sufficient to improve financial wellbeing more broadly. It suggests a more comprehensive approach moving away from asking whether people are excluded or not to asking whether they have access to accessible, acceptable and appropriate resources and supports in adverse financial circumstances. A better understanding of individuals’ financial resilience: how they bounce back from adverse financial events and the resources and supports they draw on; could help determine where resources can and should be invested to assist people to cope with financial adversity, assist the development of effective policy and, ultimately, improve financial wellbeing. This paper puts forward a definition of financial resilience and a methodology for measuring it. Australia is used as a case country from which to draw conclusions using a survey of 1496 representative adults (18+). The findings indicate that over 2 million Australian adults experienced severe or high levels of financial vulnerability raising very real concerns about financial wellbeing. Implications for academics and policy makers are presented.

     

Online Poker Tilt Scale (OPTS): creation and validation of a tilt assessment in a French population

Tilt in poker implies a deviation from an individual’s usual playing style, at a strategic, emotional and behavioural level. It is a specific characteristic of poker, which can affect all kinds of players with varying degrees of frequency. In addition, tilt could be a transitional form of pathological gambling behaviour and a gateway to addiction. The main objective of this research is therefore the design and validation of a measuring scale for tilt episode frequency in an online poker gamblers’ group. Twenty-one items based on the literature and interviews with 10 poker players were created. An online self-administered questionnaire was completed by 263 poker players to validate this scale. The mean age of the sample was 26.7 (SD = 4.45). The Online Poker Tilt Scale (OPTS) consists of 17 items and is the first validated tool for measuring the frequency of tilt episodes associated with online poker. It is composed of two factors: ‘emotional and behavioural tilt’ and ‘cognitive tilt’. Tilt seems to be an essential part of understanding online poker behaviour. This tool will enable researchers studying online poker addiction to perform research on the mechanisms and processes that lead to tilt and its consequences.     

Intervention sociology: history and foundations

Our intention is to state the main characteristics of intervention sociology, from its origins, the beginnings of which can be situated in Frédéric Le Play's monographic work carried out 150 years ago, to its present forms. Rather seldom mentioned in sociological literature or if so in the course of a paragraph or in methodological appendixes, intervention sociology, although widely practised outside the academic field, today still lacks legibility and institutional recognition. By proposing a thorough reading of the main theories and conceptions developed during the past two centuries, our article aims at explaining, through the sociological prism, the fundamental concepts of intervention sociology.     

Does digitization lead to the homogenization of cultural content?

Using weekly music charts data in 10 countries over the period 1990–2015, we analyze whether digitization leads to a trend of homogenization of music content or conversely to a greater acoustic disparity. We split the digitization era in four periods that correspond to four new emblematic distribution models (Napster, iTunes, YouTube, Spotify). Our main result is that while acoustic diversity decreased during the iTunes and the YouTube periods, the period that begins with the introduction of audio streaming services, such as Spotify, represents a turning point and is marked by a significant increase in acoustic diversity.     

电影工业的文化多样性：一项跨国研究

本文作者提出了一个评估文化多样性的框架。本文得出的主要结果：（1）国家的多样性等级次序高度依赖于其所采用的文化多样性维度;（2）电影产业得到公共支持越强大的国家（法国、欧盟和韩国）,其文化多样性越高;（3）供应多样性（supplied diversity）与消费多样性（consumed diversity）紧密相联,前者始终高于后者。这一现象揭示出对供应文化多样性的支持政策似乎与消费偏向相吻合。     

Evaluating the Move to a Linear Tax System in Germany and Other European Countries

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared. We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments, in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.

The two-sample problem with multivariate censored data: a new rank test family

A new rank test family is proposed to test the equality of two multivariate failure times distributions with censored observations. The tests are very simple: they are based on a transformation of the multivariate rank vectors to a univariate rank score and the resulting statistics belong to the familiar class of the weighted logrank test statistics. The new procedure is also applicable to multivariate observations in general, such as repeated measures, some of which may be missing. To investigate the performance of the proposed tests, a simulation study was conducted with bivariate exponential models for various censoring rates. The size and power of these tests against Lehmann alternatives were compared to the size and power of two other tests (Wei and Lachin, 1984 and Wei and Knuiman, 1987). In all simulations the new procedures provide a relatively good power and an accurate control over the size of the test. A real example from the National Cooperative Gallstone Study is given     

Two-Sample Statistics for Testing the Equality of Survival Functions Against Improper Semi-parametric Accelerated Failure Time Alternatives: An Application to the Analysis of a Breast Cancer Clinical Trial

This paper presents two-sample statistics suited for testing equality of survival functions against improper semi-parametric accelerated failure time alternatives. These tests are designed for comparing either the short- or the long-term effect of a prognostic factor, or both. These statistics are obtained as partial likelihood score statistics from a time-dependent Cox model. As a consequence, the proposed tests can be very easily implemented using widely available software. A breast cancer clinical trial is presented as an example to demonstrate the utility of the proposed tests.
