“Dissociation, posttraumatic stress symptoms, emotional dysregulation, and invalidating environments as correlates of NSSI in borderline personality …

2020

Theoretical models have proposed that inadequate caregiving environments undermine the development of adaptive regulation strategies at early stages and can lead children to inadequate regulation skills for coping with distress, such as dissociation, posttraumatic stress, and NSSI. The main aim of this work was to examine NSSI types and functions and the relationship between the aforementioned variables and lifetime NSSI in 102 patients with BPD diagnoses or BPD subthreshold symptoms. In addition, we explored the moderator role of dissociation between invalidating environments and NSSI. Results showed that 83.7% of the sample self-injured more than 5 times during their lifetime; 62.7% swall…

Trajectories of stress biomarkers and anxious-depressive symptoms from pregnancy to postpartum period in women with a trauma history

2019

Background: Cross-sectional studies have found that a trauma history can be associated with anxious-depressive symptomatology and physiological stress dysregulation in pregnant women. Methods: This prospective study examines the trajectories of both anxiety and depressive symptoms and salivary cortisol and alpha-amylase biomarkers from women with (n = 42) and without (n = 59) a trauma history at (i) 38th week of gestation (T1), (ii) 48 hours after birth (T2), and (iii) three months after birth (T3). Results: The quantile regression model showed that trauma history was associated with higher cortisol levels at T1 and this difference was sustained along T2 and T3. Conversely, there were no si…

The negative interpretation of body sensations (e.g., as sign of a severe illness) is a crucial cognitive process in pathological health anxiety (HA). However, little is known about the nature and the degree of automaticity of this interpretation bias. We applied an implicit association test (IAT) in 20 subjects during functional magnetic resonance imaging (fMRI) to investigate behavioral and neural correlates of implicit attitudes towards symptom words. On the behavioral level, body symptom words elicited strong negative implicit association effects, as indexed by slowed reaction times when symptom words were paired with the attribute “harmless” (incongruent condition) relative to a contro…

Prevalence and determinants of secondary posttraumatic growth following trauma work among medical personnel: a cross sectional study.

2021

ABSTRACT Background: People helping trauma victims as a part of their work may experience positive results, known as Secondary Posttraumatic Growth (SPTG). Aim: The present study aimed to determine the prevalence and determinants of SPTG among medical personnel, considering occupational load, job satisfaction, social support, and cognitive processing of trauma, understood as cognitive coping strategies. Methods: Subjects comprised 419 representatives of the medical profession, including paramedics and nurses. The age of the subjects varied from 19 to 65 (M = 39.60; SD = 11.03). Four standard measurement tools were utilized: the Secondary Posttraumatic Growth Inventory, the Job Satisfaction …

Loan loss provisions. A study by economic cycles

2017

Este trabajo estudia los determinantes de las dotaciones para provisiones del deterioro de los créditos en las entidades de crédito españolas desde 1983 al segundo trimestre de 2013. Resultan significativos, además de la morosidad, las provisiones genéricas, el margen de interés, la estacionalidad centrada en el cuarto trimestre y los periodos de crisis. Al ser un periodo extenso se estudian cómo actúan los determinantes en cada uno de los 4 ciclos económicos que se han dado. Se encuentran similitudes importantes en los periodos de crisis y en los periodos de crecimiento, junto a las singularidades de los propios ciclos. Las aportaciones de esta investigación son: i) el diferente comportami…

Informal, formal institutions and credit: complements or substitutes?

2019

AbstractThis paper analyses the relationship between informal institutions measured by social trust and the provision of private credit. Research on the trust–finance relationship abounds, although most of it is confined to the micro-level, with far fewer contributions from a wide, cross-country perspective. Considering a sample of 119 economies in the period 1993–2015, results suggest that social trust is an important determinant of private credit, and that its effects are transmitted indirectly via some particular aspects of the quality of economic-judicial institutions. In addition, and contrary to previous findings in related areas, substitutive effects for informal and formal instituti…

Contributions to Branch-and-Price-and-Cut Algorithms for Routing Problems

2019

This article deals with new exact branch-and-price-and-cut algorithms for the solution of routing problems. Specialized methods for the pickup-and-delivery problem (PDP), the truck-and-trailer routing problem (TTRP), the periodic vehicle routing problem (PVRP) and a service network design and hub location problem (SNDHLP) are presented. We develop a new technique for the acceleration of bidirectional labeling algorithms by a dynamic choice of the merge point. Moreover, for variants of the PDP, the bidirectional labeling can be effectively applied for the first time. In the TTRP, we model the extension to a 2 days planning horizon and the consideration of a quantity-dependent transfer time. …

Branch-and-Price-and-Cut for the Periodic Vehicle Routing Problem with Flexible Schedule Structures

2019

This paper addresses the periodic vehicle routing problem with time windows (PVRPTW). Therein, customers require one or several visits during a planning horizon of several periods. The possible visiting patterns (schedules) per customer are limited. In the classical PVRPTW, it is common to assume that each customer requires a specific visit frequency and offers all corresponding schedules with regular intervals between the visits. In this paper, we permit all kinds of schedule structures and the choice of the service frequency. We present an exact branch-and-price-and-cut algorithm for the classical PVRPTW and its variant with flexible schedules. The pricing problems are elementary shortes…

The periodic rural postman problem with irregular services on mixed graphs

2019

Abstract In this paper, we deal with an extension of the rural postman problem in which some links of a mixed graph must be traversed a given number of times over a time horizon. These links represent entities that must be serviced a specified number of times in some subsets of days (or periods) of the time horizon. The aim is to design a set of minimum-cost tours, one for each day/period of the time horizon, that satisfy the service requirements. We refer to this problem as the periodic rural postman problem with irregular services (PRPP–IS). Some practical applications of the problem can be found in road maintenance operations and road network surveillance, for example. In order to solve …
