Several studies have posited that authentic leadership (AL) and transformational leadership (TFL) imply ethical behaviour that can mitigate tendencies towards low engagement at work. However, there is a lack of studies analysing, for the same sample, the effect of both styles as a job resource and their effects on employees’ engagement as a means of facilitating their work goals and reducing their job demands. This study addresses this shortcoming by analysing the relations of both leadership styles to vigor, an affective construct, and engagement at work, a motivational outcome. Moreover, the possible mediation effect of vigor at work on the relationship between both leadership styles and engagement is considered. Finally, we explore the differential contributions of both styles to employees’ resources. A sample of Spanish employees (N = 215; 48.8% female) under the supervision of a direct leader responded concerning the TFL and AL of their closest supervisor and their own vigor at work and engagement. Our results show that vigor increases the effect of both leadership styles on engagement. Moreover, TFL, to a greater extent than AL, relates to higher engagement. Thus, vigor as an affective dimension mediates the effect of positive leadership on engagement. This study considers, for the same sample, the effects of two related, albeit different, leadership styles. The results indicate that AL and TFL are positively perceived by employees as creating a climate of energy that acts as a resource (both organizational and personal). Practitioners could enhance employees’ vigor at work and engagement by promoting these two leadership styles., This research was supported by theSpanish Ministry of Science and Innovation MCIN/AEI/10.13039/ 501100011033 project number PID2020-116521RB-I00 and by a predoctoral fellowship (FPU18/00302)

A favorable ecological orientation does not guarantee specific knowledge or its translation into sustainable behaviors. The objective was to analyze environmental awareness, ecological beliefs, and behaviors among healthcare professionals and their relationships with individual, professional, and institutional characteristics. METHODS Cross-sectional observational study in 450 healthcare professionals and managers. Environmental awareness and behaviors were assessed using the Healthcare Environmental Awareness Tool (HEAT), and ecological beliefs using the New Ecological Paradigm for Health (NEP-Health). Overall, scale and subscale scores, associations between instruments, and associations with sociodemographic and professional variables were analyzed. RESULTS The mean HEAT score was 173.35 ± 26.44 (69.30% of the theoretical maximum) and the NEP-Health score was 60.20 ± 8.22 (80.30%). The HEAT scales related to beliefs about the health impact of knowledge (HAS-2) and professional (HPEB-2) and personal (PEB-2) ecological behaviors reached 81% of their theoretical maxima, compared with 55–60% for knowledge (HAS-1) and the frequency of professional and personal ecological behaviors (HPEB-1 and PEB-1). HEAT and NEP-Health were positively correlated (r = 0.28; p < 0.001), particularly in belief subscales. Training and knowledge of the existence of a hospital environmental management system showed consistent associations with HEAT. CONCLUSION Professionals showed a favorable ecological orientation, with relative scores higher than those for knowledge and behavior frequency. The gap between ecological orientation and its translation into applied knowledge and sustainable practices supports the development of educational and institutional strategies aimed at addressing it.

To achieve carbon neutrality by 2050, many companies have started implementing sustainability policies. The aim of this work, as result of collaboration between Universities and companies, is to assess the environmental impacts associated with the production of alternative formulations of porcelain stoneware. The proposed formulations contain extraction scraps and chamotte and have promising technological properties. A comparative analysis of the life cycle in three different scenarios was carried out to assess the environmental footprint of the final products. The analyzed scenarios were a glazed porcelain stoneware (which was taken as a reference and is commercially available), a porcelain stoneware containing pumice scraps, and one containing volcanic lapillus scraps. It was observed that the transportation of raw materials has the largest environmental impact, followed by the production and extraction of the raw materials themselves. From the performed analysis, it was possible to observe that by replacing the currently used materials by the ones hereby studied, environmental benefits can be obtained. In particular, depending on the considered pollutant, the environmental impact can be reduced between a minimum of about 8 % (Freshwater Aquatic Ecotoxicity category) to a maximum of 48 % (Acidification category). In a time when raw materials supply is difficult, the use of scraps, which would otherwise be disposed of, is particularly interesting and can lead to the production of an environmentally friendly product.

This spreadsheet includes the final databases obtained in the process described in the article "Optimizing rule weights to improve FRBS clustering in wireless sensor networks". The optimized weights for each of the analyzed scenarios can be found in the file., Wireless sensor networks (WSNs) are usually composed of tenths or hundredths of nodes powered by batteries that need efficient resource management to achieve the WSN goals. One of the techniques used to manage WSN resources is clustering, thus nodes are grouped into clusters around a cluster head (CH) which must be chosen carefully. In this article, it is presented a new centralized clustering algorithm based on a Type-1 fuzzy logic controller that infers the probability for each node of becoming a CH. The main novelty presented is that the fuzzy logic controller employs three different knowledge bases (KBs) during the lifetime of the WSN. The first KB is used from the beginning to the instant when the first node depletes its battery, the second KB is then applied from that moment to the instant when half of the nodes are dead, and the last KB is loaded after that point until the last node runs out of power. These three KBs have been obtained from the original KB designed by the authors after an optimization process. It is based on a Particle Swarm Optimization algorithm that maximizes the lifetime of the WSN in those three periods by adjusting each rule in those KBs through the assignment of a weight value ranging from 0 to 1. This optimization process is used to obtain better results in complex systems where the number of variables or rules could make it unaffordable. The results of the present optimized approach improve significantly upon those from other authors with similar methods. Finally, the paper presents an analysis on why some rule weights change more than others in order to design more suitable controllers in the future.

We sampled the diversity of pollen dispersed by solitary bees by using bee trap nests in 12 paired olive farms located in 6 localities from Andalusia in 2020. On the one hand, each paired olive farm is constituted by an olive farm with low-intensive herb cover management and an olive farm with intensive herb cover management. The low-intensive management consists of the maintenance of herb cover during most of the year being only removed in late spring by mechanic mowing or cattle. Conversely, intensive management consists of removing the herb cover permanently by using pre-emergence and/ or post-emergence herbicides sometimes in combination with ploughing the ground several times a year. On the other hand, each paired farm in each locality is surrounded by the same landscape complexity. We classified each paired farm in three categories of landscape complexity (simple, intermediate, and complex) according to the proportion of semi-natural area estimated within a 2 km radius buffer around the centroid of each pair of farms. We use 144 bee trap nests in total, using two different materials and four cavity diameters (40× ca. 9 mm bamboo, 20× ca. 12 mm reed internodes, 20× ca. 15 mm reed internodes and 4× ca. 20 mm reed internodes), providing a total of 84 nesting cavities per nest. On each farm, six nests were set in March, matching the period of activity in the phenology of these solitary bees and the flowering plants they pollinate. Bee trap nests were set in different microhabitats (i.e. olive orchard matrix and non-productive areas). Trap nest colonization was monitored monthly, from April to September. For every cavity colonized, samples of three different pollen packs were extracted and dyed using fuchsine. Samples were identified under microscope to species.
