Crowdfunding in Europe: Between Fragmentation and Harmonization
2020
AbstractThe European crowdfunding market is growing rapidly, especially in continental Europe. At the same time, cross-border activities are still constrained. Fragmented markets, especially caused by differences in regulation, are an obstacle to growth of crowdfunding platforms. The European Union introduced the European Crowdfunding Service Provider (ECSP) Regime in 2019. This harmonized regime applies to crowdfunding platforms intermediating equity and debt investments between businesses and retail investors. This chapter discusses evidence on the fragmented nature of the European crowdfunding market, while presenting the ECSP directive, as a critical regulatory initiative towards harmon…
Soil interpretation in the context of anthropedogenic transformations and pedotechniques application
2018
Abstract Following a long and vigorous study carried out by the International Committee on Anthropogenic Soils (ICOMANTH), the Soil Taxonomy (ST) classification system recently incorporated a number of changes to include Human-Altered and Human-Transported soils, generally called anthropogenic soils. These changes underwent careful scrutiny as they affect the current classification of existing soil series, and as the proposals and logics are as yet untested against existing data and descriptions. Particular attention was given to the diagnostic characteristics of the anthropogenic soils and to the Subgroups for Human-Altered and Human-Transported soils. In this study, we consider a frequent…

Cognitive behavioural therapy and mindfulness for stress and burnout : a waiting list controlled pilot study comparing treatments for parents of chil…
2018
Background Parents of children with chronic conditions often experience a crisis with serious mental health problems for themselves as a consequence. The healthcare focus is on the children; however, the parents often worry about their children's health and future but are seldom offered any counselling or guidance. Aim The aim of this study was to investigate the effectiveness of two group-based behavioural interventions on stress and burnout among parents of children with chronic conditions. Design, participants and setting After a waiting list control period (n = 28), parents were offered either a cognitive behavioural (CBT, n = 10) or a mindfulness program (MF, n = 9). Results Both inter…

On Language Adequacy
2015
Abstract The paper concentrates on the problem of adequate reflection of fragments of reality via expressions of language and inter-subjective knowledge about these fragments, called here, in brief, language adequacy. This problem is formulated in several aspects, the most general one being: the compatibility of the language syntax with its bi-level semantics: intensional and extensional. In this paper, various aspects of language adequacy find their logical explication on the ground of the formal-logical theory of syntax T of any categorial language L generated by the so-called classical categorial grammar, and also on the ground of its extension to the bi-level, intensional and ex- tensio…
Anterior cervical discectomy and fusion is more effective than cervical arthroplasty in relieving atypical symptoms in patients with cervical spondyl…
2022
Background and purpose Patients with cervical spondylosis often present with concurrent 'atypical symptoms' of unknown etiology that have been associated with cervical spondylotic disease, including dizziness, headache, nausea, tinnitus, blurred vision, palpitations, and memory and gastrointestinal disturbances. Few studies have addressed whether surgical intervention to treat classic symptoms of cervical spondylosis can also effectively alleviate atypical symptoms. Accordingly, the purpose of this study is to compare the ability of cervical arthroplasty (CA) and anterior cervical discectomy and fusion (ACDF) to alleviate atypical symptoms associated with cervical spondylosis. Materials and…
Safety and efficacy of cervical disc arthroplasty in preventing the adjacent segment disease: a meta-analysis of mid- to long-term outcomes in prospe…
2019
Objectives: Cervical disc arthroplasty (CDA) has become an alternative treatment for cervical radiculopathy and myelopathy. This technique preserves appropriate motion at both the index and adjacent disc levels and consequently may prevent adjacent segment degeneration (ASD). The authors performed a meta-analysis to compare the safety and efficacy of CDA to those of the gold standard, anterior cervical discectomy and fusion (ACDF). Both surgical and clinical parameters were employed to verify the hypothesis that CDA can reduce the risk of ASD. Methods: The meta-analysis comprised high-quality randomized controlled trials that compared CDA and ACDF treatments of cervical degenerative disc di…
Modelowanie metodami ab initio i DFT właściwości spektroskopowych wybranych pochodnych ftalocyjaniny
2017
Odkryte na początku XX wieku ftalocyjaniny to interesująca klasa związków chemicznych. Dzięki obecności cyklicznego polienu spełniającego regułę Huckla struktury chemiczne tych związków są bardzo trwałe, a w pierścieniach benzenowych na obrzeżach tych związków można umieścić podstawniki. Można modyfikować w ten sposób właściwości ftalocyjaniny takie jak rozpuszczalność czy zdolność katalityczną. Jednak najważniejszą cechą tych związków są sprzężone wiązania podwójne, dzięki którym wykazują one absorpcję światła w zakresie widzialnym. Ftalocyjaniny i ich pochodne znajdują zastosowanie między innymi jako barwniki, katalizatory, fotouczulacze, sensory chemiczne i komórki światłoczułe w panelac…
