New insigths relating to the beginning of the Neolithic in the eastern Spain: Evaluating empirical data and modelled predictions
2018
Abstract In this paper we present recent research concerning the neolithization process in the East of Spain, evaluating the time span between the last hunther-gatherer groups and the first farmers ( c . 5950–5150 cal. BC). To do that we have compiled and filtered current information about radiocarbon dates and sites in order to discuss the state of the art relating to the models used to explain the Neolithic spread in the region. In this sense we compare archaeological data with recent results of virtual model (ABM) in accordance with the scenarios and mechanisms proposed. On this basis we evaluate the empirical data relating to the current model for explaining the Neolithic spread at the …
Studying radical organizational innovation through grounded theory
2000
The main aim of this article is to study the social processes occurring during the implementation of radical organizational innovation. Our aim is to understand the nature of the development of radical innovation by identifying the social processes, that are taking place. The perspective for the analysis stems from grounded theory as a generative and inductive analytical strategy (Glaser & Strauss, 1967). An in-depth case study was thoroughly analysed. A total of 14 indepth interviews were conducted with key informants selected according to theoretical sampling criteria. The systematic use of the constant comparative method allowed us to differentiate grounded theories leading to a c…
Nucleon-to-Delta transition form factors in chiral effective field theory using the complex-mass scheme
2018
We calculate the form factors of the electromagnetic nucleon-to-$\Delta$-resonance transition to third chiral order in manifestly Lorentz-invariant chiral effective field theory. For the purpose of generating a systematic power counting, the complex-mass scheme is applied in combination with the small-scale expansion. We fit the results to available empirical data.
Spectroscopic Properties of Nuclear Skyrme Energy Density Functionals
2014
We address the question of how to improve the agreement between theoretical nuclear single-particle energies (SPEs) and experiment. Empirically, in doubly magic nuclei, the SPEs can be deduced from spectroscopic properties of odd nuclei that have one more, or one less neutron or proton. Theoretically, bare SPEs, before being confronted with experiment, must be corrected for the effects of the particle-vibration-coupling (PVC). In the present work, we determine the PVC corrections in a fully self-consistent way. Then, we adjust the SPEs, with PVC corrections included, to empirical data. In this way, the agreement with experiment, on average, improves; nevertheless, large discrepancies still …
Electromagnetic transition form factors of the Roper resonance in a phenomenological field theory
2014
We analyze the form factors of the electromagnetic nucleon-to-Roper-resonance transition in the framework of a low-energy phenomenological field theory. A systematic power-counting procedure is generated by applying the complex-mass scheme. Within this power counting we calculate the form factors to next-to-next-to-leading order and fit the results to empirical data.
Evolution of strategy narration and leadership work in the digital era
2019
This paper examines the evolution of strategy narration, contributing to ongoing discussions in this field. Our empirical data, gathered from a large Finnish co-operative bank, cover three decades. According to our findings, digitalisation has brought about an epoch change in strategy narration, as top management has strongly adopted digital media in their leadership work, which has replaced ‘traditional’ face-to-face strategy meetings and public presentations by gatherings on digital platforms, including webcasting, intranet and Skype. This has brought about a leadership vacuum, and left organisational members long for their superiors to ‘exercise’ some traditional leadership practices, su…
KAMA: A Temperature-Driven Model of Mate Choice Using Dynamic Partner Representations
2008
KAMA is a model of mate-choice based on a gradual, stochastic process of building up representations of potential partners through encounters and dating, ultimately leading to marriage. Individuals must attempt to find a suitable mate in a limited amount of time with only partial knowledge of the individuals in the pool of potential candidates. Individuals have multiple-valued character profiles, which describe a number of their characteristics (physical beauty, potential earning power, etc.), as well as preference profiles, that specify their degree of preference for those characteristics in members of the opposite sex. A process of encounters and dating allows individuals to gradually bui…
El carácter transdiagnóstico de las intrusiones mentales: una revisión y una propuesta basada en datos.
2018
Abstract: The transdiagnostic nature of mental intrusions: A review and data-based proposal. The objective of a transdiagnostic perspective in psychopathology is to better understand the commonalities among clinically different mental disorders on the basis of a set of shared etiopathogenic dimensions and processes. Unwanted intrusive cognitions (UI) and their functional consequences had been proposed as symptom dimensions in Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Hypochondriasis (HYP) and Eating Disorders (EDs). In this article, we review the empirical data about the putative transdiagnostic nature of UI and their functional consequences in the four mentioned …
The 'Second Wave' of Spanish Clinical Legal Education: Empirical, Pedagogical and Institutional Lessons for a Pilot Course and Program at the Univers…
2019
Spanish clinicians today benefit from the ‘first wave’ of early adopters. We also benefit from decades of clinical scholarship — most recently about the Western European and global clinical legal education movements — and empirical data on what lawyers actually do and need in practice. In this article, the authors summarize key empirical, pedagogical, and institutional lessons to ground the creation of a pilot course and program at the University of Granada.
Catecholamine Response Curves of Male Hypertensives Identified by Lehmacher's Two Sample Configural Frequency Analysis
1997
A new application of LEHMACHER'S (1980) marginal homogeneity sign tests is given by analysis of bivariate response curves (or response surfaces) in two unpaired samples of hypertensive versus normotensive patients. Rationale and computations are illustrated by empirical data from sympathomedullary stress research.
