Institutional framework for quality and safety assurance of aquaculture products in Bosni And Herzegovina

One of the major characteristics of Bosnia and Herzegovina (B&H) aquaculture production is its long tradition. However, the war that happened in B&H (1992-1995) resulted in destruction of the most of the production infrastructure. Since then, modern !sh production and processing facilities have been reestablished and trade in !sh and !sh products has recommenced. Further expansion of the B&H aquaculture has been o"cially identi!ed as an important source of overall agriculture development, as well as the key sector able to ful!ll the international, particularly the European Union (EU) requirements for trade, faster than other sectors in B&H agriculture. During the negotiation of export license to the EU, the proper authorities, in particular the State Veterinary O"ce of Bosnia and Herzegovina (SVO) of the Ministry of Foreign Trade and Economic Relations (MoFTER), and other stakeholders identi!ed the lack of capacity in ful!lling some of the EU requirements on aquatic animal health management and food safety issues. In order to overcome the problem, the SVO and the MoFTER asked for FAO assistance, which resulted in o"cial approval of the FAO project “Strengthening capacity on aquaculture health management in Bosnia and Herzegovina”. In this paper authors present institutional framework for quality and safety assurance of aquaculture products in B&H as a part of mentioned problems

Measuring the importance of communication skills in tourism

Tourism service providers need to have expressive communication skills to be able to offer a better tourism product and create a pleasant tourist experience. To better understand, conceptualize, and achieve the multidimensional concept of communication skills, this paper aims to investigate the literature and propose a measurement scale adapted to the modern tourism workplace. Results, based on a literature review and questionnaire survey, show that five communication skill dimensions emerge: written, oral, listening, digital, and non-verbal communication skills. The paper’s theoretical contribution is the systematization of the literature and the conceptualization of communication skills up to date, while its empirical contribution is based on the examination of collected data related to the validated scale measurement. The scale presented in this paper will assist future empirical research on communication skills required in the field of tourism. The paper will help generate novel research questions for identifying and analyzing acquired communication skills

CONSUMER SEGMENTS IN BLOCKCHAIN TECHNOLOGY ADOPTION

Recent research has highlighted the adoption of blockchain technology (BCT) and the increasing recognition of its multiple capabilities for users. The main objective of this paper is to delineate different consumer segments based on their BCT beliefs and attitudes. Using a survey method, 934 questionnaires were collected and subjected to hierarchical and K-Means cluster analysis and contingency analysis. The results reveal four identifiable user segments with respect to BCT adoption: Innovators (enthusiastic about BCT), Cautious (careful about BCT), Sceptics (doubtful about BCT), and Suspicious (very distrustful about BCT). These results provide valuable insights into understanding behavioral intentions and serve as a basis for future research

Recommendations for the preservation of environmental samples in diatom metabarcoding studies

Implementation of DNA metabarcoding for diatoms for environmental monitoring is now moving from a research to an operational phase, requiring rigorous guidelines and standards. In particular, the first steps of the diatom metabarcoding process, which consist of sampling and storage, have been addressed in various ways in scientific and pilot studies and now need to be rationalised. The objective of this study was to compare three currently applied preservation protocols through different storage durations (ranging from one day to one year) for phytobenthos and phytoplankton samples intended for diatom DNA metabarcoding analysis. The experimental design used samples from four freshwater and two marine sites of diverse ecological characteristics. The impact of the sample preservation and storage duration was assessed through diatom metabarcoding endpoints: DNA quality and quantity, diversity and richness, diatom assemblage composition and ecological index values (for freshwater samples). The yield and quality of extracted DNA only decreased for freshwater phytobenthos samples preserved with ethanol. Diatom diversity was not affected and their taxonomic composition predominantly reflected the site origin. Only rare taxa (< 100 reads) differed among preservation methods and storage durations. For biomonitoring purposes, freshwater ecological index values were not affected by the preservation method and storage duration tested (including ethanol preservation), all treatments returning the same ecological status for a site. This study contributes to consolidating diatom metabarcoding. Thus, accompanied by operational standards, the method will be ready to be confidently deployed and prescribed in future regulatory monitoring

Pandrug-Resistant Acinetobacter baumannii Causing Nosocomial Infections in a University Hospital, Taiwan

The rapid emergence (from 0% before 1998 to 6.5% in 2000) of pandrug-resistant Acinetobacter baumannii (PDRAB) was noted in a university hospital in Taiwan. To understand the epidemiology of these isolates, we studied 203 PDRAB isolates, taken from January 1999 to April 2000: 199 from 73 hospitalized patients treated at different clinical settings in the hospital and 4 from environmental sites in an intensive-care unit. Pulsed-field gel electrophoresis analysis and random amplified polymorphic DNA (RAPD) generated by arbitrarily primed polymerase chain reaction of these 203 isolates showed 10 closely related genotypes (10 clones). One (clone 5), belonging to pulsotype E and RAPD pattern 5, predominated (64 isolates, mostly from patients in intensive care). Increasing use of carbapenems and ciprofloxacin (selective pressure) as well as clonal dissemination might have contributed to the wide spread of PDRAB in this hospital

The future for Mediterranean wetlands: 50 key issues and 50 important conservation research questions

Wetlands are critically important for biodiversity and human wellbeing, but face a range of challenges. This is especially true in the Mediterranean region, where wetlands support endemic and threatened species and remain integral to human societies, but have been severely degraded in recent decades. Here, in order to raise awareness of future challenges and opportunities for Mediterranean wetlands, and to inform proactive research and management, we identified (a) 50 key issues that might affect Mediterranean wetlands between 2020 and 2050, and (b) 50 important research questions that, if answered, would have the greatest impact on the conservation of Mediterranean wetlands between 2020 and 2050. We gathered ideas through an online survey and review of recent literature. A diverse assessment panel prioritised ideas through an iterative, anonymised, Delphi-like process of scoring, voting and discussion. The prioritised issues included some that are already well known but likely to have a large impact on Mediterranean wetlands in the next 30 years (e.g. the accumulation of dams and reservoirs, plastic pollution and weak governance), and some that are currently overlooked in the context of Mediterranean wetlands (e.g. increasing desalination capacity and development of antimicrobial resistance). Questions largely focused on how best to carry out conservation interventions, or understanding the impacts of threats to inform conservation decision-making. This analysis will support research, policy and practice related to environmental conservation and sustainable development in the Mediterranean, and provides a model for similar analyses elsewhere in the world

The Mediterranean Island Wetlands (MedIsWet) inventory: strengths and shortfalls of the currently available floristic data

MedIsWet (Conservation of the island wetlands of the Mediterranean Basin) is a MAVA funded project which aims at investigating all seasonal or permanent island wetlands both natural and artificial, with a minimum extent of 0.1 hectares. More than 16,000 wetlands from almost all the Mediterranean, including islands from France, Italy, Malta, Croatia, Cyprus, Tunisia, Turkey, Greece and Spain were mapped. Over 2,500 of them were inventoried in the field and more than 500 scientific contributions catalogued. In total, more than 35,000 plant occurrences were uploaded, in a standardised and comparable way, on the national open-source web portals. These can be related to the recorded threats, uses and other spatially retrievable information. Here, we show strengths and shortfalls of the already available information about the floristic records. Although further improvements are needed, we discuss how these data can be used for research and policy actions and to develop conservation projects
