Burnout-related ill-being at work : Associations between mindfulness and acceptance skills, worksite factors, and experienced well-being in life
2018
The aim of this paper was to investigate the associations between mindfulness and acceptance (MAA) skills and burnout-related ill-being at work (ILLB) after eliminating the impact of worksite (WS) and general well-being in life (WELLB) factors. The results were derived from data on employees (n = 168) of varying professional backgrounds, who experienced relatively high levels of burnout. Analyses were conducted using structural equation modelling (SEM) and the Cholesky decomposition method, since these allow for the investigation of multiple measures and multiple factors in relation to one another. In relation to ill-being at work, the analyses revealed a general MAA factor as well as a spe…
Structural validity of the Spanish Wechsler Intelligence Scale for Children–Fourth Edition in a large sample of Spanish children with attention-defic…
2018
The factorial structure of the WISC-IV for 859 Spanish children diagnosed with ADHD was examined. A bifactor model with the four factors first identified by Wechsler (2003a) was the best fit to the...
Structure of Arabic Scale of Death Anxiety With Chinese College Students: A Bifactor Approach
2018
The Arabic Scale of Death Anxiety (ASDA), as one of the most widely used measures of death anxiety (DA), has increasingly been applied in many studies. However, the structures derived from different studies are highly inconsistent. In this study, both traditional and novel (bifactor) modeling approaches were used, to investigate the most optimal structure of the ASDA in a sample of 984 Chinese college students. After a series of comparisons, the results showed that the bifactor model, with a dominant general DA factor and three distinct sub-dimensions, was the most optimal measurement structure, and measurement invariance of this bifactor model between sexes was also confirmed. Based on the…
The Italian Version of the Inventory of Interpersonal Problems (IIP-32): Psychometric Properties and Factor Structure in Clinical and Non-clinical Gr…
2018
All versions of the Inventory of Interpersonal Problems (IIP) are broadly used to measure people's interpersonal functioning. The aims of the current study are: (a) to examine the psychometric properties and factor structure of the Italian version of the Inventory of Interpersonal Problems-short version (IIP-32); and (b) to evaluate its associations with core symptoms of different eating disorders. One thousand two hundred and twenty three participants (n = 623 non-clinical and n = 600 clinical participants with eating disorders and obesity) filled out the Inventory of Interpersonal Problems-short version (IIP-32) along with measures of self-esteem (Rosenberg Self-Esteem Scale, RSES), psych…
The Impact of Intellectual Capital on the SMEs Performance: A Study of the Romanian Central Region SMEs
2021
Abstract The 21st century is the century of change and maybe one of the most important changes in the organizations’ life is the transition from focusing on the development of the tangible assets to the development of the intangible assets and the interest for attracting human resources capable to generate performance. The survival of many companies depends on their willingness and capacity to adapt to such changes. (Abdulaali, 2018) In this dynamic and complex economic system, the intangible assets of organizations become primary, being decisive for the organizations’ performance. In the new economic competition, intangible assets provide a sustainable competitive advantage, intellectual c…
A Framework to Measure Intellectual Capital
2016
New technologies have changed the structure of companies shifting the focus of creating value from material resources to intangibles. The competitive advantage is increasingly reliant on the presence of specific intangibles such as knowledge, experience, communication skills that are the main source of competitive advantage. Among the intangibles based on knowledge, intellectual capital certainly occupies a prominent place. In recent years the increasing complexity that characterized the business management influenced companies to adopt new models of reporting and accounting, taking into account issues and intangible factors not considered so far with the right attention. The objective of t…
Variable Fixing for Two-Arc Sequences in Branch-Price-and-Cut Algorithms on Path-Based Models
2020
Variable fixing by reduced costs is a popular technique for accelerating the solution process of mixed-integer linear programs. For vehicle-routing problems solved by branch-price-and-cut algorithms, it is possible to fix to zero the variables associated with all routes containing at least one arc from a subset of arcs determined according to the dual solution of a linear relaxation. This is equivalent to removing these arcs from the network used to generate the routes. In this paper, we extend this technique to routes containing sequences of two arcs. Such sequences or their arcs cannot be removed directly from the network because routes traversing only one arc of a sequence might still b…
The facility location problem with capacity transfers
2020
Abstract This paper explores the concept of capacity transfer in the context of capacitated facility location problems. This is accomplished by assuming that facilities with surplus capacity/production can cooperate with those facing shortage by transferring part of that capacity/production. Such a transfer incurs a cost that nonetheless may be compensated by savings both in the installation costs and in the distribution costs. Mixed-integer mathematical programming models are proposed for the problem. A distinction is made between the case in which the triangle inequality holds for the transfer costs and the case in which it does not. We present compact models, which are enhanced with vali…
From bus to tramway: Is there an economic impact of substituting a rapid mass transit system? An empirical investigation accounting for anticipation …
2018
Abstract Hedonic pricing models and price equations have been extensively used to retrieve the implicit prices of urban externalities through real estate markets. Many applications have been devoted to investigating the impact of new mass transit systems, such as rail infrastructures. However, the implementation of such infrastructures usually takes some time and markets can react with an anticipation effect that can vary according to the different development phases. Moreover, the impact may be different if it acts as a substitute to existing rapid transit services. This paper focuses on the impact of substituting bus rapid transit (BRT) for light rail transit (LRT) services, taking into a…
