The Acceptable Alternative Vehicle Fuel Price
2019
Historically, petroleum fuels have been the dominant fuel used for land transport. However, the growing need for sustainable national economics has urged us to incorporate more economical and ecological alternative vehicle fuels. The advantages and disadvantages of them complicate the decision-making process and compel us to develop adequate mathematical methods. Alternative fuel (compressed natural gas, liquefied petroleum gas, and ethanol fuel mixtures), the standard prices and their ratios were investigated. A mathematical model to determine a critical ratio between alternative and conventional fuel prices had already been developed. The results of this were investigated. The results sho…
Minimally Invasive Video-Assisted Thyroidectomy: Analysis of Complications From a Systematic Review
2019
Background. Nowadays, minimally invasive video-assisted thyroidectomy (MIVAT) is considered a safe and effective option. However, its complication rate has not been specifically discussed yet. The aim of this systematic review was enrolling a large number of studies to estimate early and late complications (transient and definitive, uni- and bilateral laryngeal nerve palsy; transient and definitive hypocalcemia; cervical hematoma; hypertrophic or keloid scar) of MIVAT compared with conventional technique. Methods. The review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria in PubMed and Embase. Search terms were “minimally inva…
Dynamic Potential of Feedback in Self-Regulated Learning and Motivation of Children with Mathematical Learning Difficulties
2017
The present study was designed to examine the effects of feedback conditions on learning and motivation of children identified with mathematical learning difficulties (MLDs). The performance of 76 fifth grade children on computational math skills and related task motivation was assessed. The groups of children were randomly assigned to one of two treatment conditions: immediate corrective feedback or delayed conventional feedback on two occasions. Results showed that children performed significantly better when they were provided with the immediate corrective feedback than when they were provided with the delayed conventional feedback. The findings suggest that provision of the immediate co…
What makes a citrus farmer go 'organic'? Empirical evidence from Spanish citrus farming
2012
Organic farming is increasing its share of total world food output and receiving grow-ing support from policymakers concerned with agricultural sustainability issues. This paper studies the characteristics of citrus farmers in the Spanish region of Valencia that affect their probability of becoming organic farmers. A fair understanding of these characteristics may help policymakers improve the design of agricultural policies aimed at supporting organic citrus practices. As regards the methodology, a probit model is estimated with information from a sample of conventional and organic citrus farmers obtained from a survey designed for a larger research project aimed at analysing Valencian cit…

Substrat jako fundament konwencjonalizacji wtórnej sielanki staropolskiej
2022
Artykuł pt. Substrat jako fundament konwencjonalizacji wtórnej staropolskiej sielanki jest analizą najważniejszej zasady tworzącej konwencję tego gatunku, a mianowicie reguły dwupłaszczyznowości kompozycyjnej. Autorka na przykładach utworów takich poetów, jak: Szymon Szymonowicz, Szymon Zimorowicz, Jan Gawiński, Samuel Twardowski czy Adrian Wieszczycki omawia etap kształtowania się konwencji gatunku sielankowego. Następnie ukazuje zależność pomiędzy zmianami w warunkach literackich i kulturowych oraz tych, które zaszły w percepcji czytelników, a ich wpływem na ewolucję ustalonej konwencji. Obserwowane zmiany w obrębie konwencji zostały opracowane w odniesieniu do koncepcji substratu gatunko…
ENVIRONMENTAL FOOTPRINT REDUCTION FOR WASTEWATER TREATMENT BY MULTI-OBJECTIVE OPTIMIZATION AND MODELLING
2020
The current challenge faced by researchers and managers is minimize the environmental footprint of wastewater treatment plants (WWTPs). To accomplish this goal, other than respect legal requirements, WWTPs must provide better responses regarding consumption of energy and resources, greenhouse gas (GHG) emissions, among others. The research hereby presented is based on the application of mathematical modelling with the aim to propose a framework for the minimization of WWTP’s environmental footprint towards optimization techniques. A literature review was held to gain knowledge regarding the main decision support systems (DSS) that are applied to WWTPs since they allow selecting the most app…
Viittomakielet hybridisysteemeinä - hämärärajaisuus ja epäkonventionaalisuus osana viittomakielten rakennetta
2018
Tässä artikkelissa tarkastellaan hämärärajaisuutta ja epäkonventionaalisuutta osana joitakin kaikista viittomakielistä löydettyjä yksiköitä ja rakenteita ja niiden käyttöä. Täsmällisemmin artikkelin fokuksessa ovat tietyt muodoltaan ja merkitykseltään tilanteisesti muuntuvat viittomat (erityisesti niin kutsutut osittain leksikaaliset viittomat) sekä eräänlainen vaihteleva-asteinen näytteleminen (niin kutsuttu konstruoitu toiminta), jota viittojat käyttävät tuottamiensa syntaktisten rakenteiden osana ja niiden sijaan. Käytännössä artikkeli esittelee näkemyksen, jonka mukaan molemmissa tarkastelun kohteena olevissa ilmiöissä on kyse samasta asiasta eli kielen diskreettien ja konventionaaliste…

Globalization and Trade: An Unfortunate Tangle
2019
Globalization disrupted the seemingly solid construction emerged in the aftermath of WW II, called the international trade system. For over fifty years, the system grew constantly thanks to the increasing number of countries that joint it as well as to its ubiquitously-accepted rules. For better and for worse the system has worked according to traditional theory principles, whose core credo was that all participating countries would gain more if engaged in trade than if in autarchy. Globalization has muddied the waters. The contemporary order in which multinational companies make the rules has made these predictions look elusive. One serious implication is today’s unorthodox approach of tra…
