A Follower-Centric Approach to Leadership in the Newsroom     

Manuel Goyanes  Alessandro Gentile 《Journalism Practice》2018,12(4):509-525

This article analyses leadership in the newsroom of the Spanish newspaper El País as well as its impact on the craft of journalism more generally. Through 23 in-depth interviews, we try to elucidate how the newsroom constructs its leaders (in the newsroom, what does it mean to be a leader?), paying particular attention to the main skills considered to be necessary. According to our newsroom findings, not all heads of section or editors-in-chief are leaders, a fact that questions formal authority relations and proclaims expertise and know-how as discriminatory skills. This study emphasizes that the collective recognition of a leader is not an ultimate disposition, but can vary over time: consequently leaders who do not achieve the professional requirements of the newsroom can be denied the status, despite their expertise and experience. Our findings indicate that leaders at El País are those journalists (no matter what their positions) with strong capacities and skills (fundamentally experience, expertise and creativity) to manage form (relationships) and substance (contents) in the daily work of the newsroom. In short, journalists seen as leaders combine reiterated and strong qualities and merit, graphically reflected in the texts they have published for years in the newspaper.  相似文献   

Spectroscopic methods for the analysis of celadonite and glauconite in Roman green wall paintings     

Ligia Maria Moretto  Emilio Francesco Orsega  Gian Antonio Mazzocchin 《Journal of Cultural Heritage》2011,12(4):384

One set of samples from wall paintings of the X^th Regio of Italy containing green colours was analysed exploiting different spectroscopic techniques, aiming to identify the pigments used. The possibility to distinguish between glauconite and celadonite, the most common green pigments used in such paintings, was of particular interest. Samples of celadonite from Monte Baldo and glauconite from Belgium were considered as standard materials for comparison. The results obtained using FTIR, EDS, AAS, Colorimetry, Raman and EPR spectroscopies were compared for the identification of the green pigments.  相似文献

Global exact tracking for uncertain MIMO linear systems by output feedback sliding mode control     

Eduardo V.L. Nunes  Alessandro J. Peixoto  Tiago Roux Oliveira  Liu Hsu 《Journal of The Franklin Institute》2014

This paper presents a solution to the problem of global exact output tracking for uncertain MIMO (multiple-input–multiple-output) linear plants with non-uniform arbitrary relative degree using output feedback sliding mode control. The key idea to overcome the relative degree obstacle is to generalize our previous hybrid estimation scheme to a multivariable version by combining, through switching, a standard linear lead filter with a non-linear one based on robust exact differentiators, achieving uniform global exponential practical stability and exact tracking.  相似文献   

Temperament Dimensions in Preschool Children: Links With Cognitive and Affective Theory of Mind     

Emiddia Longobardi  Pietro Spataro  Marta D’Alessandro  Rita Cerutti 《Early education and development》2017,28(4):377-395

Research Findings: The present cross-sectional study investigated the question of whether 6 different temperament dimensions (inhibition to novelty, social orientation, motor activity, positive emotionality, negative emotionality, and attention) influenced cognitive and affective theory of mind (ToM) in 168 children (86 three/four-year-olds and 82 four/five-year-olds). Temperament was measured via a parent-report questionnaire, cognitive ToM via a classical false-belief task, and affective ToM via a comprehensive test tapping 3 levels of emotion comprehension (external, mental, and reflexive). In addition, language competence was assessed with a direct test evaluating both receptive and expressive language. The results showed that after we controlled for language ability, inhibition to novelty predicted higher levels of cognitive ToM in 4/5-year-old children. In addition, higher levels of social orientation predicted better comprehension of the external aspects of emotion in both younger and older children. Practice or Policy: Our results highlight the importance of the early identification of less sociable children, who might benefit from training interventions aimed at increasing their affective ToM abilities. At the same time, they are also consistent with previous evidence indicating that an inhibited approach to social interaction can promote false-belief understanding.  相似文献   

On the Shapley value and its application to the Italian VQR research assessment exercise     

Camil Demetrescu  Francesco Lupia  Angelo Mendicelli  Andrea Ribichini  Francesco Scarcello  Marco Schaerf 《Journal of Informetrics》2019,13(1):87-104

Research assessment exercises have now become common evaluation tools in a number of countries. These exercises have the goal of guiding merit-based public funds allocation, stimulating improvement of research productivity through competition and assessing the impact of adopted research support policies. One case in point is Italy's most recent research assessment effort, VQR 2011–2014 (Research Quality Evaluation), which, in addition to research institutions, also evaluated university departments, and individuals in some cases (i.e., recently hired research staff and members of PhD committees). However, the way an institution's score was divided, according to VQR rules, between its constituent departments or its staff members does not enjoy many desirable properties well known from coalitional game theory (e.g., budget balance, fairness, marginality). We propose, instead, an alternative score division rule that is based on the notion of Shapley value, a well known solution concept in coalitional game theory, which enjoys the desirable properties mentioned above. For a significant test case (namely, Sapienza University of Rome, the largest university in Italy), we present a detailed comparison of the scores obtained, for substructures and individuals, by applying the official VQR rules, with those resulting from Shapley value computations. We show that there are significant differences in the resulting scores, making room for improvements in the allocation rules used in research assessment exercises.  相似文献   

Three-dimensional kinematic analysis of the golf swing using instantaneous screw axis theory,Part 2: golf swing kinematic sequence     

Alessandro Vena  Dave Budney  Tom Forest  Jason P. Carey 《Sports Engineering》2011,13(3):125-133

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique, instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study, the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular velocity relative to that segment’s ISA and verify that ISA theory is a valid tool to analyse segment rotation during the golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore, ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that motion about the ISA is representative of joint motion.  相似文献   

On IT systems and knowledge sharing in MNCs: a lesson from Siemens AG     

Francesco?CiabuschiEmail author 《知识管理研究与实践》2005,3(2):87-96

This explorative case study aims at shedding light on the utilization of a specific Intranet-based knowledge-sharing platform, the ShareNet. This system is part of a €1bn investment campaign to transform Siemens into an e-driven company, and it is an important example of system enabling knowledge sharing between local subsidiaries within large multinationals. By investigating how such company-wide system is structured and employed a theoretical model and three propositions about IT contribution to intra-firm knowledge sharing are formulated. Findings lead to the conclusion that, on one hand, IT systems represent an efficient mechanism for knowledge duplication through imitation between units with similar capabilities and, on the other, as a trigger for direct interaction resulting in knowledge development through joint problem solving between units having complementary capabilities.  相似文献   

The impact of national research funds: A regression discontinuity approach to the Chilean FONDECYT     

José Miguel Benavente  Alessandro Maffioli 《Research Policy》2012,41(8):1461-1475

This paper analyses the role of national research funds in promoting scientific production in emerging economies. The study focuses on the impact of the Chilean National Science and Technology Research Fund (FONDECYT). The analysis uses data drawn from international sources of bibliometric information combined with the administrative records of the program's executing unit. To measure the program's impact, we implement a regression discontinuity (RD) design on principal researchers who applied for funding between 1988 and 1997 considering as outcomes both quantity (publications up to 2002) and quality (citations up to 2005) of their scientific production. Our results show significant and positive impact in terms of publications, but no impact in terms of quality of scientific production in the proximity of the program's threshold ranking.  相似文献
