Examining the critical factors that influence the success of construction and demolition waste reverse logistics operations
2022
The reverse logistics (RL) performance of construction and demolition waste (C&DW) differs significantly between countries. Although some countries are successfully circular, other countries are still far behind; with C&DW being largely directed to landfills or being illegally dumped. There is a lack of guidelines on the requirements for transitioning countries towards C&DW diversion, and little attention has been given to the factors that influence the success of C&DW RL and increased circularity. This study aims to develop a framework that helps in structuring and assessing the success of C&DW RL on a regional level and serves as a guide for transitioning developing co…
Qualitative Evaluation of the STOEMP Network in Ghent: An Intersectoral Approach to Make Healthy and Sustainable Food Available to All
2020
The STOEMP network is, to our knowledge, one of the first initiatives to bring different sectors together in a municipality so as to increase accessibility to healthy and sustainable foods for all, with particular attention for the disadvantaged population. This qualitative study aimed to gain an in-depth insight into how the STOEMP network aims to reach its goal of making healthy, sustainable food available to everyone, through an intersectoral, collaborative process, exploring the facilitators and challenges of taking a systems-oriented approach to achieving this. Interviews were conducted among 15 stakeholders of the STOEMP network between March&ndash
Intervāltreniņu programmas ietekme uz kardiovaskulārā riska faktoriem 2. tipa cukura diabēta pacientiem
2019
KOPSAVILKUMS Augstas intensitātes intervāltreniņi (HIIT) 2. tipa cukura diabēta (T2D) pacientiem ievērojami uzlabo glikēmijas kontroli un pozitīvi ietekmē kardiovaskulārā riska faktorus, bet tie ir grūti tolerējami, un par HIIT alternatīvu var kļūt intervālās staigāšanas treniņi ar intermitējošu intensitāti. Mūsdienās viens no veidiem, kā integrēt fiziskās aktivitātes ikdienā, ir treniņi specializēto mobilo aplikāciju vadībā. Pētījuma mērķis bija noskaidrot ar mobilā tālruņa lietotni vadīto augstas intensitātes staigāšanas intervāltreniņu ietekmi uz kardiovaskulārā riska faktoriem T2D pacientiem randomizētā kotrolētā pētījumā. Materiāli un metodes: 56 brīvprātīgie 35- 75 gadus veci T2D paci…
Ultrasensitive and highly specific detection of iodine ions using zirconium (IV)-enhanced oxidation
2022
Nuclear energy has significantly promoted the development of human society. However, nuclear pollution caused by nuclear accidents can lead to significant hazards to the environment and human health. As a major radioactive product, radioactive iodine (mainly existing as I−) detection has attracted significant attentions. In this study, zirconium(IV) is used to enhance the oxidation of environmental I− to form I2. Subsequently, the generated I2 oxidizes the chemical chromogenic substrate 3,3′,5,5′-tetramethylbenzidine, which is used for I− detection and realizes an ultralow limit of detection (LoD) of 0.176 nM. The LoD of our method, to the best of our knowledge, is the lowest among those of…
Power Production from Produced Waters via Reverse Electrodialysis: A Preliminary Assessment
2022
Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because of their environmental impact. An approach widely used in the oil industry is the reinjection of this wastewater into the extraction wells after a suitable treatment. The high salt concentration of such solutions may be used in salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) is one of the most promising. In this work, the application of RED for energy generatio…
Building sustainable contextual ambidexterity through routines: a case study from information technology firms
2020
The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …
Kokeilu kirjoittamisen itsearvioinnista tietokoneella
2001
This article discusses an experiment which we are conducting in the field of Finnish as a second language. We are developing an Internet-based program that learners of Finnish can use to assess their own writing skills. The program code originally comes from the DIALANG project, which is developing a diagnostic language assessment system for 14 languages for the Internet. We selected two new writing tasks for the program, and constructed related sets of benchmark performances to enable the learners to assess their own abilities. In the article, we first discuss the concepts of learner autonomy and self-assessment, in other words the theoretical framework that underlies the program. This is …
Starptautisko tiesību pārkāpumi Aquarius incidentā
2019
Bakalaura darbā tiek apskatīts 2018. gada jūnijā Vidusjūrā notikušais incidents, kad Itālija un Malta atteica ienākt savās ostās nevalstisko organizāciju pārvaldītajam kuģim „Aquarius” ar uz tā izglābtiem 629 migrantiem. Darba ietvaros tiek analizēts starptautisko jūras tiesību regulējums attiecībā uz meklēšanas un glābšanas operācijām ar mērķi konstatēt, vai valsts var atteikt pieeju savām ostām tikko izglābtām personām. Pētījuma rezultātā tiek sniegti priekšlikumi attiecībā uz konstatētajiem trūkumiem regulējumā par valstu rīcību pēc izglābto personu nonākšanas uz palīdzību sniedzošā kuģa. Tāpat darba ietvaros tiek analizētas Eiropas Cilvēka tiesību un pamatbrīvību aizsardzības konvencija…
ASPECTS REGARDING THE OPTIMIZATION OF THE QUALITY OF MANAGERIAL DECISIONS - SOLVING AN OPTIMIZATION PROBLEM IN THE SENSE OF SUSTAINABILITY WITH WINQSB
2012
In this paper we present an optimization problem solving, problem that is mathematically shaped as a linear programming problem. This is made with the purpose of finding an optimal solution which is also a sustainable one. In the present and future society, it is clear that nothing can be done honestly, but only in the sense of a professional and sustainable thinking (Konrad, C., 2011, pp.202-217, Petrescu, I., 2006, p.1). To think sustainable can also mean “to be calculated”, in popular language “to choose wisely”, all for achieving the proposed project, being careful to using non-renewable resources, to pollution, to protection for human resource, etc. Of course that the logical and preci…
PREMISES OF GASTRONOMIC TOURISM
2013
Since the competition among tourism destinations has risen, local culture has developed into a competitive advantage and a priceless resource of new products and services to attract and captivate tourists. Gastronomy plays a vital role in the process of attracting tourists because food has an important part in the tourist experience, plus gastronomy developed over the year's styles and tastes and become a critical source of establishing patterns in postmodern civilization.
