The influence of age-based faultlines on team performance: Examining mediational paths
2021
Abstract In a sample of 60 branches of a bank, we examine the influence of age-based faultlines on team performance. Specifically, we propose a model with four mediational paths in the age-based faultline-team performance link. Using a time-lagged design with three data-collection points, we found that task conflict, team reflexivity, and negative team mood mediated the negative relationship between age-based faultline strength and team performance. The results reveal the value of examining different mediational paths to explain the negative impact of teams’ demographic faultlines on team performance, and the need to integrate both task-related and affective aspects of team work in order to…
Accounting for operating environments in measuring water utilities’ managerial efficiency
2009
In this paper adjusted input-specific scores of technical efficiency are computed for a sample of Spanish water utilities. Performance is adjusted by netting out efficiency scores from the effect of operating environments and statistical noise. The results show that computation of adjusted efficiency scores at the input level manifestly improves the assessment of utilities’ performance in our sample of water utilities. In addition, several environmental variables capable of affecting input-specific technical management are discovered, ownership or demand seasonality among them. Finally, distributions of conventional and adjusted scores of technical performance are found to be statistically …
Four Conceptual Perspectives of Innovation Components
2019
The study provides a detailed analysis of high impact to market innovations, without sorting whether these are innovations of low or high technological progress. The research base sample includes a detailed analysis of 58 consumer product innovations that reached a high market impact over the period 2014–2017, i.e. the consumers purchased them considerably more than other innovations. The study examines the components of these innovations in detail; they are also grouped into 4 basic groups. It is concluded in the study that the high impact to market innovations are made up of recurring 34 components. The study also concludes that the open innovation components only partly overlap with the …
'Where Have I Heard It?' Assessing the Recall of Traffic Safety Campaigns in the Dominican Republic
2021
Although traffic crashes are the eighth leading cause of death in the world, and are linked to vehicle and infrastructure-related factors, crash-related fatality rates are much higher in lowincome countries. Particularly, the Dominican Republic is the country with the highest accident rate in the whole American continent. Therefore, in the past few years, public agencies have been developing different measures aimed at reducing traffic fatalities, including road safety campaigns. The aim of the present study was to assess the recalling of such campaigns among the Dominican population, which may serve as an additional indicator to evaluate their effectiveness in this and other countries of t…
Multivariate Assessment of Procedures for Molecularly Imprinted Polymer Synthesis for Pesticides Determination in Environmental and Agricultural Samp…
2021
In the case of quantitative and qualitative analysis of pesticides in environmental and food samples, it is required to perform a sample pre-treatment process. It allows to minimalize the impact of interferences on the final results, as well as increase the recovery rate. Nowadays, apart from routinely employed sample preparation techniques such as solid-phase extraction (SPE) or solid-phase microextraction (SPME), the application of molecularly imprinted polymers (MIPs) is gaining greater popularity. It is mainly related to their physicochemical properties, sorption capacity and selectivity, thermo-mechanical resistance, as well as a wide range of polymerization techniques allowing to obta…
Citizens’ perceptions in relation to transport systems and infrastructures: a nationwide study in the dominican republic
2021
One of the challenges currently faced by emerging countries is to get their citizens to decide to use sustainable transport for their regular trips, in order to reduce the current vehicular pollution rates. The objective of this descriptive research is to examine the perceptions of Dominicans regarding the state of the country’s transport systems and road infrastructure. For this purpose, a nationwide survey procedure was performed. This cross-sectional research used the data retrieved from a sample of 1260 citizens aged over 18, proportional in gender, age, habitat, and province of the Dominican Republic. The results showed how Dominicans believe that, compared to other road features, pede…
A CASE STUDY OF THE APPLICATION OF HAND-HELD MOBILE LASER SCANNING IN THE PLANNING OF AN ITALIAN FOREST (ALPE DI CATENAIA, TUSCANY)
2021
Abstract. Precision forestry is becoming a key sector for forest planning because it allows complex analyses of forest data to be carried out simply and economically. It contributes to the integration between technicians and operators in the sector by guaranteeing the transparency of the forest management operations (Corona et al., 2017). In the context of the progressive development of technology, we investigated the feasibility of using the hand-held mobile laser scanner (HMLS) system in different types of forest sites and comparison of the characteristics of individual trees (tree height, diameters at breast height) with traditional surveys, applied with the aim to validate the performan…
Nitrous oxide fluxes from permafrost regions
2020
This dataset is a synthesis of published nitrous oxide (N2O) fluxes from permafrost-affected soils in Arctic, Antarctic, and Alpine permafrost regions. The data includes mean N2O flux rates measured under field (in situ) conditions and in intact plant-soil systems (mesocosms) under near-field conditions. The dataset further includes explanatory environmental parameters such as meteorological data, soil physical-chemical properties, as well as site and experimental information. Data has been synthesized from published studies (see 'Further details'), and in some cases the authors of published studies have been contacted for additional site-level information. The dataset includes studies publ…
Antidoping Science
2018
The ineffectiveness of antidoping programs in elite sport, largely due to human and political factors, is leading to a new resolve and greater transparency of antidoping authorities and those stakeholders interested in drug-free sport. The perception by the public, athletes, and the World Anti-Doping Agency (WADA) of antidoping science and current drug testing programs in elite sport varies widely from "ineffective" to "robust and reliable." Here, we discuss why a careful and considered reevaluation of the underlying premise of antidoping science is needed to bring this unique application of predictive/diagnostic science more in line with other areas of medicine. We show how the validity of…
The Dynamic Evolution of the Proximity Effect in the Textile Industry
2011
This paper tests the evolution of the relationship between localization and proximity and their effect on firm performance for a sample of 10,490 Spanish textile firms in the period 2001–2006. Using coefficients of specialization two levels of geographical disaggregation are distinguished: (i) the provincial cluster and (ii) the industrial district. The results obtained show a positive and significant impact of the specialization level on productivity, both for industrial districts and provincial clusters (in this case only when the levels of specialization are high enough). In general, the effect is higher for industrial districts than for provincial clusters, although in both cases it dec…
