Adaptation and psychometric data of the Exploration of Natural Metalinguistic Skills in Aphasia Protocol (MetAphAs) - Chilean version.
2019
This study aimed to cross culturally adapt the Protocol for the Exploration of Natural Metalinguistic Skills in Aphasia (MetAphAs), contributing to the future application in the aphasic Chilean population.The sample corresponds to 72 healthy subjects in the region of Valparaíso, between the ages of 50 to 85. The MetAphAs measures natural metalinguistic skills and presents the basic elements on which to base the exploration of the metacognitive dimensions involved in verbal behavior. The validity was ascertained by means of Cronbach's Alpha Coefficient, including the values of each of the 6 sections; the correlations between variables were analyzed by the Pearson coefficient.We observed that…
Quality of Life in Dementia: Impact of Cognition and Insight on Applicability of the SF-36
2011
Comparability of measures of quality of life in dementia and in other diagnostic groups, such as mild cognitive impairment, normal aging, or other diseases, is highly desirable. However, the impact of cognitive deficits and impaired insight on applicability and validity of generic instruments is sparsely studied.Sixty patients with dementia [38 women; age: mean (SD) = 78.7 (6.4) years; Mini-Mental State Examination (MMSE): mean (SD) = 20.2 (6.0)] recruited as part of the start-modem study, a multicenter care research study in Germany, completed the generic instrument SF-36 and the specific instrument Quality of Life-Alzheimer's Disease (QOL-AD).QOL-AD self-rating scores [mean (SD) = 32.8 (5…
Multidimensional Sexual Well-being Scale for Older Adults: Validity Evidence from a Polish Sample
2021
Here, we report the results of a Polish adaptation of the Multidimensional Sexual Well-being Scale (MSWBS) for older adults. The MSWBS is a short self-report scale for assessing the five dimensions of an individual's sexual well-being: frequency of caressing, sexual intimacy, sexual compliance, sexual satisfaction, and sexual distress. The aim of our adaptation was to examine the utility of the scale in a country with conservative views on the sexuality of older people, which will help health care providers and researchers to better understand the sexual needs of older people. The study included 507 participants, aged 60-92. We found the reliability of the scale to be satisfactory (Cronbach…
Threshold rule and scaling behavior in a multi-agent supply chain
2010
In this paper an agent-based model of self organized criticality is developed in a network economy characterized by lead time and a threshold behavior of firms. Instead of considering the aggregate production of the economy as a whole, we focus on both the propagation and amplification effects of a demand shock in the sectorial productions of a multi-agent supply chain. We study a static network structure representing a relation of firms in a lower-upper stream in an industrial organization. In our model, the individual (R, nQ) policies play an important role in generating a propagation effect across the different layers of the economy, and the propagation turns into the large fluctuations …
The effect of agglomeration economies and geography on the survival of accommodation businesses in Sicily
2021
The study explores the geographical pattern of the accommodation industry in the Italian insular region of Sicily, focusing on the determinants of the risk of market exit. We adopt a standard framework of business survival analysis where agglomeration economies play an important role. We then extend the analysis by considering the role of geography to explore whether the risk of market exit depends on nearness to desirable amenities. The geography is here measured by the distance from the coast and the altitude of the place where the firm is located. When we look at the entire population of accommodation firms that started between 2010 and 2014, we find evidence that the risk of failure inc…
Job contact networks, inequality and aggregate output
2005
In this paper we study the effects of social networks on wage inequality and aggregate production. In particular, we consider a simplified version of the model by Calvo'-Armengol and Jackson (2003), with good and bad jobs and skilled and unskilled workers. Our findings are: i) increasing the number of social links increases aggregate output and may reduce inequality; ii) given a number of social connections, output increases if the average distance among worker decreases; iii) a more mixed and well-integrated society, that is a society in which heterogeneous workers share social links, produces more output and less inequality than a society in which some workers are isolated, when productiv…
Personality and the gender wage gap
2012
In this study, we investigate whether personality traits contribute towards a better understanding of the reasons for the gender wage gap. We explore whether two of the personality factors put forward by Bowles et al. (2001) as likely to be incentive enhancing in the employer–employee relationship can explain the difference in wages for women and men. These are (1) personal self efficacy (Locus of Control (LoC)) and (2) time preference. We also study the role of the so called Big Five personality traits (extraversion, emotional stability, agreeableness, openness intellect and conscientiousness), which have been associated with earnings in several recent studies. Using a sample of Dutch empl…
The effects of personality on earnings
2005
Abstract The purpose of this paper is to investigate the influence of personality dimensions on wage settings. The study was inspired by the model proposed by Bowles, Gintis, and Osborne [American Economic Review 91 (2001) 155], which shows how psychological characteristics may be rewarded or punished in the labour market due to a so-called incentive-enhancing property. Additionally, two meta-studies show that there are robust relationships between some personality dimensions and productivity [Barrick & Mount, Personnel Psychology 44 (1991) 1; Salgado, Journal of Applied Psychology 82 (1997) 30]. We used data from the DNB Household Survey (DHS) to test the extent to which certain personalit…
The effects of personality, risk and other-regarding attitudes on trust and reciprocity
2022
Abstract This paper reports experimental results on the determinants of trust and reciprocity in the context of a genuinely sequential, binary Trust Game. Apart from behavior in the main experiment, subjects’ risk attitudes and inequality aversion are elicited, as well as the traits of neuroticism and agreeableness, captured through the five-factor model. The findings suggest that trustors’ (first movers) behavior is affected by their loss aversion, while trustees’ (second movers) reciprocal behavior is not explained by any of their other-regarding attitudes, but, rather, by their agreeableness.
Methods matter: Testing competing models for designing short-scale Big-Five assessments
2015
Abstract Many psychological instruments are psychometrically inadequate because derived person-parameters are unfounded and models will be rejected using established psychometric criteria. One strategy towards improving the psychometric properties is to shorten instruments. We present and compare the following procedures for the abbreviation of self-report assessments on the Trait Self-Description Inventory in a sample of 14,347 participants: (a) Maximizing reliability/main loadings, (b) Minimizing modification indices/cross loadings, (c) the PURIFY Algorithm in Tetrad, (d) Ant Colony Optimization, and (e) a genetic algorithm. Ant Colony Optimization was superior to all other methods in imp…
