Splitting and projection: drawing on psychodynamics in educational psychology practice     

Dario W. Pellegrini 《Educational Psychology in Practice》2010,26(3):251-260

This paper reflects the author’s journey into an area of psychology which is not dominant in Educational Psychology discourse, namely psychodynamic psychology. Two psychodynamic mechanisms, namely splitting and projection are explained, and then the author describes and critiques how these mechanisms have proved useful in his practice. Two case studies are presented to illustrate how a reflective stance guided by psychodynamic concepts was fruitful in analysing and, sometimes, removing emotional obstacles in the author’s practice. Finally a hypothesis is formulated to explain the apparent lack of educational psychologists’ interest in psychodynamic psychology.  相似文献   

Microfluidic carbon-blackened polydimethylsiloxane device with reduced ultra violet background fluorescence for simultaneous two-color ultra violet/visible-laser induced fluorescence detection in single cell analysis     

Galla L  Greif D  Regtmeier J  Anselmetti D 《Biomicrofluidics》2012,6(1):14104-1410410

In single cell analysis (SCA), individual cell-specific properties and inhomogeneous cellular responses are being investigated that is not subjected to ensemble-averaging or heterogeneous cell population effects. For proteomic single cell analysis, ultra-sensitive and reproducible separation and detection techniques are essential. Microfluidic devices combined with UV laser induced fluorescence (UV-LIF) detection have been proposed to fulfill these requirements. Here, we report on a novel microfluidic chip fabrication procedure that combines straightforward production of polydimethylsiloxane (PDMS) chips with a reduced UV fluorescence background (83%-reduction) by using PDMS droplets with carbon black pigments (CBP) as additives. The CBP-droplet is placed at the point of detection, whereas the rest of the chip remains transparent, ensuring full optical control of the chip. We systematically studied the relation of the UV background fluorescence at CBP to PDMS ratios (varying from 1:10 to 1:1000) for different UV laser powers. Using a CBP/PDMS ratio of 1:20, detection of a 100 nM tryptophan solution (S/N = 3.5) was possible, providing a theoretical limit of detection of 86 nM (with S/N = 3). Via simultaneous two color UV/VIS-LIF detection, we were able to demonstrate the electrophoretic separation of an analyte mixture of 500 nM tryptophan (UV) and 5 nM fluorescein (VIS) within 30 s. As an application, two color LIF detection was also used for the electrophoretic separation of the protein content from a GFP-labeled single Spodoptera frugiperda (Sf9) insect cell. Thereby just one single peak could be measured in the visible spectral range that could be correlated with one single peak among others in the ultraviolet spectra. This indicates an identification of the labeled protein γ-PKC and envisions a further feasible identification of more than one single protein in the future.  相似文献   

Integrating best evidence into patient care: a process facilitated by a seamless integration with informatics tools     

Nunzia B Giuse  Annette M Williams  Dario A Giuse 《Journal of the Medical Library Association》2010,98(3):220-222

The Vanderbilt University paper discusses how the Eskind Biomedical Library at Vanderbilt University Medical Center transitioned from a simplistic approach that linked resources to the institutional electronic medical record system, StarPanel, to a value-added service that is designed to deliver highly relevant information. Clinical teams formulate complex patient-specific questions via an evidence-based medicine literature request basket linked to individual patient records. The paper transitions into discussing how the StarPanel approach acted as a springboard for two additional projects that use highly trained knowledge management librarians with informatics expertise to integrate evidence into both order sets and a patient portal, tlibrednaV@htlaeHyM.The Vanderbilt University Eskind Biomedical Library (EBL) has a long history of integrating evidence into clinical teams. More recently it has adapted this expertise into a more scalable approach that allows the integration of evidence into existing medical informatics tools. This paper discusses the institution''s experiences in integrating librarian-filtered evidence into informatics tools and processes, using several examples to illustrate how its knowledge management (KM) team has proactively embedded evidence provision services into the clinical care environment.  相似文献   

National vs. international journals: views of medical professionals in Croatia     

Dario SAMBUNJAK  Mirjana HUIĆ  Darko HREN  Milica KATIĆ  Ana MARUŠIĆ  Matko MARUŠIĆ 《Learned Publishing》2009,22(1):57-70

Scholarly journals, especially in non‐English‐speaking countries, may perform very different functions depending on whether they are published for national or international audiences. Four hundred and sixty‐six academic physicians and non‐academic general practitioners in Croatia were surveyed on their knowledge about two Croatian medical journals: Lije?ni?ki vjesnik (published in Croatian) and Croatian Medical Journal (published in English). The physicians were also surveyed about the importance of all national and international journals published in Croatia, and the types of articles they thought should be published in these journals. More respondents rated national (n = 329, 72.6%) than international journals (n = 275, 63.5%, P < 0.001, Wilcoxon test) as very important for the medical profession. On the other hand, publishing in international journals was more often rated as important than publishing in national journals (n = 184, 42.5% vs. n = 125, 27.8%; P < 0.001, Wilcoxon test). Guidelines for clinical practice were rated as the most important publication item in national journals, and original scientific articles in international journals.  相似文献   

The development of a mathematics teacher’s professional identity during her first year teaching     

Leticia Losano  Dario Fiorentini  Mónica Villarreal 《Journal of Mathematics Teacher Education》2018,21(3):287-315

This study is focused on a period that poses several challenges for the development of mathematics teachers’ professional identities and agency: their first year of teaching in schools. During this period, beginning mathematics teachers confront tensions and contradictions among the principles, ideals, and experiences encountered during pre-service education and the demands, and restrictions of their teaching practice in schools. This article approaches this topic by developing an interpretative case study centered on one novice mathematics teacher, Sol. The aim is to describe and understand the development of Sol’s professional identity and agency during her first teaching year. Considering identity development as a diachronic phenomenon, we carry out a narrative analysis of the research data. The findings show that Sol developed her professional identity and agency through a process that gathered together the teaching practices possible inside her school, the positions she could negotiate as a newcomer inside the institution, and the cultural practices and discourses embodied during pre-service education. The results bring to the forefront the profound and tense interactions between the intimate and personal terrain of mathematics teachers and the social and cultural world of the schools where they work. Sol’s case also contributes to understanding the role that a robust pre-service education can play in the development of beginning teachers’ professional identities and in the possibility they could become agents of transformation in their schools.  相似文献   

Longitudinal Relations among Maternal Self-Efficacy,Maternal Warmth,and Early Adolescents’ Prosocial Behavior     

Bernadette Paula Luengo Kanacri  Concetta Pastorelli  Eriona Thartori  Carolina Lunetti  Laura Di Giunta  Dario Bacchini 《Parenting, science and practice》2021,21(1):24-46

SYNOPSIS

Objective. This article examined two-wave longitudinal paths among maternal self-efficacy, maternal warmth, and early adolescents’ prosocial behavior. Design . Participants were 194 Italian mother/child dyads from 9–13 years at the first assessment and 12–15 years at the second assessment. Using a two-wave longitudinal design, the present study tested cross-lagged paths among maternal self-efficacy, warmth, and early adolescents’ prosocial behavior controlling for the stability of these variables and their concurrent associations. Results . Maternal warmth mediated the link between maternal self-efficacy and adolescents’ prosocial behavior, and bi-directional effects between maternal self-efficacy and maternal warmth were found. Conclusions . These findings support a parent-driven model in the promotion of prosocial behaviors across early adolescence and a general need to consider simultaneously parental cognitions (maternal self-efficacy) and actions (maternal warmth) in explaining adolescents’ prosocial behaviors. Implications for parenting program interventions are discussed.  相似文献   

Persistence of innovation and patterns of firm growth     

Dario Guarascio  Federico Tamagni 《Research Policy》2019,48(6):1493-1512

In this work we exploit a long-in-time panel of Spanish manufacturing firms observed during the period 1990–2012 to examine the long-run contribution of innovation persistence to sales growth and market share dynamics. We examine two main research questions. First, do persistent innovators grow more than other firms? Second, do persistent innovators show more persistent growth patterns over time compared to other firms? We find negative answers to both questions: firms that persistently innovate over the first decade, do not grow more and do not display more persistent growth dynamics in the succeeding years, regardless of whether innovation persistence is defined in terms of R&D, patenting activity, or product or process innovation. These findings lend support to luck and random theories of firm growth, in turn challenging innovation persistence theories commonly suggesting that persistent innovators enjoy large and sustained comparative advantages.  相似文献   

Sliding mode regulator as solution to optimal control problem for non-linear polynomial systems   总被引：1，自引：0，他引：1  

Michael Basin  Dario Calderon-Alvarez 《Journal of The Franklin Institute》2010,347(6):910-922

This paper presents the optimal control problem for a non-linear polynomial system with respect to a Bolza-Meyer criterion with a non-quadratic non-integral term. The optimal solution is obtained as a sliding mode control, whereas the conventional polynomial-quadratic regulator does not lead to a causal solution and, therefore, fails. Performance of the obtained optimal controller is verified in the illustrative example against the conventional polynomial-quadratic regulator that is optimal for the quadratic Bolza-Meyer criterion. The simulation results confirm an advantage in favor of the designed sliding mode control.  相似文献   

The impact of heating, lighting and people in re-using historical buildings: a case study     

Dario Camuffo  Emanuela Pagan  Adriana Bernardi  Francesca Becherini 《Journal of Cultural Heritage》2004,5(4):409-416

The impact of lighting, heating and people in re-using historical buildings are discussed for the case study concerning the ceremony room (i.e. the Giant Hall) of a mediaeval palace in Padova. The Hall has substantially four major problems for conservation: (i) the impact of heating, lighting and people when the room is used; (ii) many cracks on the oak panels of the coffered ceiling; (iii) the soiling by dust and soot particles deposited on the frescoes; (iv) the stained glass windows. A microclimate study was performed to know the impact of the environmental variables, and the use of the room, on the artworks preserved inside. The study has proved the impact of the lamps (both incandescence and compact fluorescent lamps) on the ceiling, the penetration of external air in the room, the heat and the moisture released by people, the impact of sunshine through windows and the scatter diagram of the daily cycles in temperature (T) and relative humidity (RH). During winter concerts, the strips of lead which are wrapped round the edge of the cut glass pieces in stained glass windows easily drop below the dew point and form condensation, starting corrosion. A discussion concerns the allowed variability, which should not exceed risk thresholds. A safe interval can be established within the area determined by the most frequent T and RH natural cycles. In fact, both of the cycles were compatible with the artefacts, or the artefacts were already damaged to allow the exceeding dimensional changes. Attention should be paid in the variability external to this area, especially approaching or exceeding a limit equal to twice the mode of the natural variability.  相似文献   

Haemoglobin A1c-based screening for prediabetes and diabetes mellitus: a multi-center study in Croatian adult population

IntroductionBased on the hypothesis that there is a substantial rate of adults with prediabetes and undiagnosed diabetes mellitus (DM), our aim was to perform haemoglobin A1c (HbA_1c)-based screening in a cohort of Croatian adults and estimate the prevalence of prediabetes and undiagnosed DM according to American Diabetes Association criteria.Materials and methodsThis multi-center, cross-sectional study performed in six Croatian hospitals included 5527 patients aged 40 to 70 years admitted to the Emergency Department or undergoing a primary care check-up. Haemoglobin A1c was measured from leftover whole blood samples using the enzymatic method on either Alinity c or Architect c-series analyser (Abbott Laboratories, Chicago, USA). Haemoglobin A1c between 39-47 mmol/mol was classified as prediabetes, while ≥ 48 mmol/mol as undiagnosed DM.ResultsAfter exclusion of 435 patients with known DM, the final cohort included 5092 patients (median age 57; 56% males). A total of 882 (17.3%) patients had HbA_1c values between 39 and 47 mmol/mol. There were 214 (4.2%) patients with HbA_1c ≥ 48 mmol/mol. Prediabetes prevalence ranged from 14.2% to 20.5%, while undiagnosed DM from 3.3% to 7.3%, with statistically significant differences among settings (P < 0.001). Age-stratified analysis showed that prediabetes and undiagnosed DM prevalence increase with age (P < 0.001), being 25.4% and 5.8%, respectively, in patients aged 60 to 70 years.ConclusionUnderlying impairment of glucose metabolism was identified in about one in five adults, with significant number of patients with already overt DM. These results should serve as a starting point for further steps directed towards promotion of preventive measures for DM in Croatia.  相似文献
