Impact of the Intensive Program of Emotional Intelligence (IPEI) on middle man-agers’ emotional intelligence

Background: This study aimed to evaluate the effect of the Intensive Program of Emo-tional Intelligence (IPEI; Fernández, 2015) on middle managers’ emotional intelligence, as this variable may have a significant impact on personal satisfaction, task performance, and work environment. Method: The intervention was applied on work team supervisors from a big call center, as it is an overlooked sector in this topic. Two-hundred and eighty-two supervisors from a Spanish multinational Madrid-based company (51.4% males and 48.6% females) participated in this study. Participants were assigned to the experimental group (n = 190) or the control group (n = 92) by availability, according to management decision. All supervisors filled in two questionnaires to evaluate the differ-ent components of intrapersonal emotional intelligence (i.e., attention, clarity, and repair; TMMS-24; Fernández-Berrocal, Extremera, & Ramos, 2004) and cognitive and affec-tive empathy (i.e., perspective taking, emotion understanding, empathic joy, and person-al distress; TECA; López-Pérez, Fernández, & Abad, 2008). Results: The findings showed an increase in the studied variables for the experimental group. Conclusions: The obtained results support middle managers’ training on emotional competences through short, efficient, and economic programs, and it was discussed potential limita-tions and implications of the obtained results

Особенности создания импульсных магнитных полей для магнитоуправляемой электрошлаковой плавки

Рассмотрены некоторые особенности создания импульсных магнитных полей для воздействия на кристаллизацию металла в процессе магнитоуправляемой электрошлаковой плавки. Предложены способы интенсификации электромагнитного воздействия на металлургическую ванну, основанные на использовании энергии электрических разрядов емкостных накопителей на внешний магнитный контур. Разработана экспериментальная аппаратура, включающая источник питания для генерирования электрических разрядов энергией до 1850 Дж, и магнитный контур в виде соленоида с дисковыми обмотками, охватывающими кристаллизатор. Изучены характеристики электрических разрядов при различном количестве витков магнитного контура. Показана целесообразность комплексного подхода к интенсификации электромагнитного воздействия посредством оптимизации параметров как источника разрядов, так и соответствующих магнитных контуров. Проведены экспериментальные исследования влияния импульсных магнитных полей на режимы плавки и кристаллизацию металла в процессе выплавки слитков титановых сплавов. Показана возможность при достаточной энергии разрядов и оптимальном количестве витков магнитного контура управлять порционными тепловложениями в процессе плавки, а также кристаллизацией металла слитков. При этом для улучшения качества поверхности слитков предложено воздействие осуществлять сериями импульсов, чередующихся с паузами.Some features of inducing pulsed magnetic fields for acting on metal solidification during magnetically-controlled electroslag melting are considered. Methods of intensification of electromagnetic impact on metallurgical bath are proposed, which are based on application of energy of capacitive storage electric discharges to external magnetic circuit. Experimental system has been developed, including a power source for generation of electric discharges with up to 1850 J energy, and a magnetic circuit in the form of a solenoid with disc windings enclosing the mould. Characteristics of electric discharges at different number of magnetic circuit turns have been studied. The paper shows the rationality of an integrated approach to electromagnetic impact intensification through optimization of parameters of both the discharge source and the respective magnetic circuits. Experimental investigations of the influence of pulsed magnetic fields on metal melting and solidification modes during melting of titanium alloy ingots have been performed. Ability to control discrete heat input during melting, as well as ingot metal solidification at sufficient discharge energy and optimum number of magnetic circuit turns, is demonstrated. To improve ingot surface quality, it is proposed to apply the impact in the form of series of pulses alternating with pauses

Is there a tensionless Kardar-Parisi-Zhang universality class above one dimension? An Ising model approach

The Kardar-Parisi-Zhang (KPZ) equation is a paradigm of generic scale invariance, for which it represents a conspicuous universality class. Recently, the tensionless case of this equation has been shown to provide a different universality class by itself. This class describes the -- intrinsically anomalous -- scaling of one-dimensional (1D) fronts for several physical systems that feature ballistic dynamics. In this work, we show that the evolution of certain 1D fronts defined for a 2D Ising system also belongs to the tensionless KPZ universality class. Nevertheless, the Ising fronts exhibit multiscaling, at variance with the continuous equation. The discrete nature of these fronts provides an alternative approach to assess the dynamics for the 2D front case (for a 3D Ising system), since the direct integration of the tensionless KPZ equation blows up in this case. In spite of the agreement between the 1D scaling of the Ising fronts and the tensionless KPZ equation, the fluctuation statistics in 1D and the full behavior in 2D are strongly conditioned by boundary effects.Comment: 9 pages, 9 figure

TEMPORAL AND SPATIAL DISTRIBUTION OF POACEAE POLLEN IN AREAS OF SOUTHERN UNITED KINGDOM, SPAIN AND PORTUGAL

Overall, longer Poaceae pollen seasons coincided with earlier pollen season start dates. Winter rainfall noticeably affects the intensity of Poaceae pollen seasons in Mediterranean areas, but this was not as important in Worcester. Weekly data from Worcester followed a similar pattern to that of Badajoz and Évora but at a distance of more than 1500 km and 4-5 weeks later

Secular variations of magma source compositions in the North Patagonian batholith from the Jurassic to Tertiary: Was mélange melting involved?

This study of Sr-Nd initial isotopic ratios of plutons from the North Patago nian batholith (Argentina and Chile) revealed that a secular evolution spanning 180 m.y., from the Jurassic to Neogene, can be established in terms of magma sources, which in turn are correlated with changes in the tectonic regime. The provenance and composition of end-member components in the source of mag mas are represented by the Sr-Nd initial isotopic ratios (87Sr/86Sr and 143Nd/144Nd) of the plutonic rocks. Our results support the interpretation that source compo sition was determined by incorporation of varied crustal materials and trench sediments via subduction erosion and sediment subduction into a subduction channel mélange. Subsequent melting of subducted mélanges at mantle depths and eventual reaction with the ultramafic mantle are proposed as the main causes of batholith magma generation, which was favored during periods of fast conver gence and high obliquity between the involved plates. We propose that a parental diorite (= andesite) precursor arrived at the lower arc crust, where it underwent fractionation to yield the silicic melts (granodiorites and granites) that formed the batholiths. The diorite precursor could have been in turn fractionated from a more mafic melt of basaltic andesite composition, which was formed within the mantle by complete reaction of the bulk mélanges and the peridotite. Our proposal follows model predictions on the formation of mélange diapirs that carry fertile subducted materials into hot regions of the suprasubduction mantle wedge, where mafic parental magmas of batholiths originate. This model not only accounts for the secular geochemical variations of Andean batholiths, but it also avoids a fundamental paradox of the classical basalt model: the absence of ultramafic cumulates in the lower arc crust and in the continental crust in general
