Informacja w zarządzaniu strategicznym
2016
Istotą zarządzania strategicznego jest zapewnienie bezpieczeństwa państwa w horyzoncie strategicznym. Strategia bezpieczeństwa państwa powinna gwarantować stabilny jego rozwój poprzez klasyczne racjonalne zarządzanie, to znaczy świadome i planowe stosowanie różnych metod i technik, które wpływają na decyzje podejmowane przez instytucje i organizacje państwowe. Informacje, odgrywając rolę niezależnego czynnika w środowisku bezpieczeństwa państwa, stopniowo stają się głównym ogniwem każdego konfliktu. Informacje wpływają na zdolności zarządzania w prowadzonych działaniach, zmniejszają lub zwiększają możliwości.
Production and energetic performance of Carthamus tinctorius L. in the Mediterranean environment
2012
One of the most important aspects when managing an agro-energy crop is the energy gain factor, that is, the surplus in energy which remains following an appraisal of the relevant inputs and outputs. This aspect is of fundamental importance when choosing a species in a particular growth environment as it gives crucial information on the economic and energetic feasibility of a species and allows us to evaluate potential costs in order to obtain a given production and energy performance. In the agro-energy sector, this indicator is not always included in the evaluation process, making the agronomic and energy results obtained often incomplete. In the Mediterranean area, one potential crop for …
Harnessing Molecular Fluorophores in the Carbon Dots Matrix: The Case of Safranin O
2022
The origin of fluorescence in carbon dots (C-dots) is still a puzzling phenomenon. The emission is, in most of the cases, due to molecular fluorophores formed in situ during the synthesis. The carbonization during C-dots processing does not allow, however, a fine control of the properties and makes finding the source of the fluorescence a challenging task. In this work, we present a strategy to embed a pre-formed fluorescent molecule, safranin O dye, into an amorphous carbonaceous dot obtained by citric acid carbonization. The dye is introduced in the melted solution of citric acid and after pyrolysis remains incorporated in a carbonaceous matrix to form red-emitting C-dots that are strongl…
Homophobic bullying and preventive actions at school: from laws to gender studies in Italy
2019
The evolution of thought relating to sexual orientation and the greater visibility of gay and lesbian people, at media level also, haven’t been efficient for the revisiting of homosexual rendering from public acceptance and for a cultural transformation. The violent events on young homosexual students urge to reflect on the need that trainers should introduce educational models capable of providing different models of gender identification, fighting the stereotype that tries to substitute the reality itself. The homophobic bullying is intended as a fight to safety and well-being of young students. A multi-disciplinary and network approach seems to be for health practitioners a valid startin…
Vanadium Toxicity Monitored by Fertilization Outcomes and Metal Related Proteolytic Activities in Paracentrotus lividus Embryos
2022
Metal pharmaceutical residues often represent emerging toxic pollutants of the aquatic environment, as wastewater treatment plants do not sufficiently remove these compounds. Recently, vanadium (V) derivatives have been considered as potential therapeutic factors in several diseases, however, only limited information is available about their impact on aquatic environments. This study used sea urchin embryos (Paracentrotus lividus) to test V toxicity, as it is known they are sensitive to V doses from environmentally relevant to very cytotoxic levels (50 nM; 100 nM; 500 nM; 1 µM; 50 µM; 100 µM; 500 µM; and 1 mM). We used two approaches: The fertilization test (FT) and …
Leveraging National Auditing Criteria to Implement Cybersecurity Safeguards for the Automotive Emergency Response Vehicles : A case study from Finland
2017
A modern Emergency Response Vehicle (ERV) is a combination of emergency services and functional mobile office on the wheels. The mobile office is aiming to leverage the benefits of fixed office while moving on the wheels. Researchers have observed that emergency response personnel including Law Enforcement Authorities (LEAs), Police and border guards, could be on the duty while having possibility to use same services compared to fixed office. On the one hand, demand of mobile office has significantly improved the emergency response services. On the other hand, emergency vehicle designers should rethink the demand of users. This resulted into modern standard emergency response vehicle with t…
Preventing occupational injury among police officers: does motivation matter?
2017
Background: Injury prevention is an important issue for police officers, but the effectiveness of prevention initiatives is dependent on officers’ motivation toward, and adherence to, recommended health and safety guidelines. Aims: To understand effects of police officers’ motivation to prevent occupational injury on beliefs about safety and adherence to injury prevention behaviours. Methods: Full-time police officers completed a survey comprising validated psychometric scales to assess autonomous, controlled and amotivated forms of motivation (Treatment Self-Regulation Questionnaire), behavioural adherence (Self-reported Treatment Adherence Scale) and beliefs (Safety Attitude Questionnaire…
Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists
2018
The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…
Time domain symmetry parameters analysis for series arc fault detection
2022
This paper presents a feasibility study of exploiting the symmetry of some parameters for series arc fault detection in electrical circuits. The considered parameters are defined in the time domain and they are based on the current signal derivative and the evaluation of cross-correlation between subsequent observation windows. The analysis is carried out for AC systems, starting from an experimental characterization, which has been carried out in accordance with the Standard UL 1699 requirements for "unwanted tripping tests"and "operation inhibition tests"of arc fault circuit interrupters (AFCIs). The results obtained in different load conditions show that the proposed parameters can be us…
Valorization of Side Stream Products from Sea Cage Fattened Bluefin Tuna (Thunnus thynnus): Production and In Vitro Bioactivity Evaluation of Enriche…
2022
The valorization of side streams from fishery and aquaculture value-chains is a valuable solution to address one of the challenges of the circular economy: turning wastes into profit. Side streams produced after filleting of sea cage fattened bluefin tuna (Thunnus thynnus) were analyzed for proximate composition and fatty acid profile to evaluate the possibility of producing tuna oil (TO) as a valuable source of ω-3 polyunsaturated fatty acids (PUFA) and testing its bioactivity in vitro. Ethyl esters of total fatty acids (TFA), obtained from TO, were pre-enriched by urea complexation (PUFA-Ue) and then enriched by short path distillation (SPD) up to almost 85% of the PUFA fraction (PU…
