Despite the well-known positive consequences of transformational coaches in sport, there is still little research exploring the mechanisms through which coaches&rsquo

Associations between Adolescents’ Interpersonal Relationships, School Well-being, and Academic Achievement during Educational Transitions

2020

AbstractA youth’s ability to adapt during educational transitions has long-term, positive impacts on their academic achievement and mental health. Although supportive relationships with parents, peers, and teachers are protective factors associated with successful educational transitions, little is known about the reciprocal link between the quality of these interpersonal relationships and school well-being, with even less known about how these two constructs affect academic achievement. This longitudinal study examined how the quality of interpersonal relationships and school well-being worked together to affect academic achievement during the transition from primary school to lower second…

Natural history of the Sprint Fidelis lead: survival analysis from a large single-center study.

2012

The purposes of our study were to: (1) determine lead failure rate in a large single-center cohort of Sprint Fidelis 6949 (Fidelis) leads, (2) define the risk of lead failure over time, (3) assess the impact of the Lead Integrity Alert (LIA) on lead failure presentation, and (4) identify independent predictors of Fidelis lead failure. All patients who underwent implantation of a Fidelis lead between September 2004 and July 2007 were included. Demographic, clinical, and device characteristics at the time of implant and prior to failure were collected and analyzed. A total of 971 Fidelis leads (706 men, 265 women, mean age 68.4 ± 12.8 years) were implanted. Over a mean follow-up of 46.3 month…

Is atrial sensing of ventricular far-field signals important in single-lead VDD pacing?

1998

UNLABELLED In single-lead VDD pacing the atrial sensitivity frequently is programmed to sensitive values. Atrial sensing of ventricular far-field signals should be reduced by differential atrial sensing. The aim of the study was to evaluate the effectiveness of this approach. METHODS The study included 10 patients with a single-lead VDD pacemaker (Thera 8948, Lead 5032). The atrial sensitivity was set to its most sensitive value of 0.18 mV and the telemetered intraatrial EGM was continuously recorded. After atrial tracked ventricular pacing, VVI pacing was performed with pacing rates from 100 to 160 beats/min in steps of 10 beats/min and up to 165 beats/min. The peak-to-peak amplitudes of P…

Paroxysmal atrial fibrillation and high degree AV block: use of single-lead VDDR pacing with mode switching.

1998

Dual chamber rate responsive pacing incorporating a mode switching option is increasingly used in patients with chronic paroxysmal atrial fibrillation and high degree AV block. Single-lead VDDR pacemakers have rarely used for this indication. The purpose of this study was to determine their reliability of atrial sensing during atrial fibrillation, the percentage of atrial synchronous ventricular pacing, and the behavior of the sinus rate outside the phases of atrial fibrillation. We studied ten patients with a single-lead VDDR pacemaker implanted for this indication. Follow-up visits were performed at predischarge and after 1, 3, 6, 12, 18, and 24 months. During the mean follow-up period of…

Transformational capabilities of ICT: A technology management perspective in construction

2008

(1) The construction industry typically lags behind in adopting technology. (2) Given the fact that the process of construction is critically dependent on relevant, accurate and timely information, ICT can play a very important role in the industry. (3) The industry is actually missing out on the crucial advantages offered by ICT. ICT is used by and large as mere enhancement tools, not as agents that can transform and thus revolutionize the process of construction. (4) A new approach based on the technology management principles will enable researchers to formulate new strategic directions. (5) This paper will explore successful technology management strategies in the context of ICT impleme…

Application of geomarketing to coastal tourism areas

2019

Geomarketing allows geographic units to be defined with a certain degree of homogeneity in terms of tourist preferences, behaviours, needs, expectations, buying and consumption patterns, and analogous attitudes. The result is a “territorial segmentation” of the demand in accordance with the geographic characteristics of tourism areas. The objective of this work is to analyse the strengths and weaknesses of applying geomarketing to the territorial segmentation of demand in coastal tourism areas. An empirical analysis of hotels specialising in family tourism in tourist accommodation establishments in Costa Adeje (Spain) is presented. The main conclusion is that the tourist accommodation varia…

Identification and study of research groups in Learning, Teaching and Education Leadership

2016

The bibliometrical indicators, based on the statistical analysis of quantitative data from scientific literature, are currently an essential tool to the study researchers’ activity. In these lasts years, the use of bibliometrical indicators as a complement to other scientific indicators to analyse the research situation of a country, its evolution in time and its position in the international context has been extended.  The objective of this study is to analyse the scientific productivity in Learning, Teaching and Education Leadership throughout the communications presented in all of the World Conference on Learning, Teaching and Education Leadership (WCLTA) included in the database Web …

The human side of leadership: Inspirational leadership effects on follower characteristics and happiness at work (HAW)

2020

Abstract Leadership has received significant attention over the past years. Now is the time to refine how leaders impact on followers and their attitudes. This study examines how inspirational leaders influence follower characteristics (FC), and in turn, their happiness at work. In this study, the mediating effect of follower characteristics in the relationship between inspirational leadership and happiness at work was specifically examined. Data was gathered from 389 frontline banking employees working in Italian and Spanish banks. A confirmatory factor analysis revealed a positive partial mediating role of follower characteristics in the relationship between inspirational leadership and h…
