Relevance of trade facilitation in emerging countries exports

2012

The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.

Mismatch negativity (MMN) in freely-moving rats with several experimental controls.

2014

Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…

Burnout, work engagement and workaholism among highly educated employees: Profiles, antecedents and outcomes

2014

The present study examined the longitudinal profiles of burnout, engagement and workaholism among highly educated employees. First, the latent profile modeling indicated two latent classes: Engaged and Exhausted-Workaholic. Second, the results revealed that employees with the Engaged profile experienced high levels of energy and dedication, whereas employees with the Exhausted-Workaholic profile experienced exhaustion, cynicism and workaholism. Social pessimism in the transition from high education to work predicted poor subjective well-being at work. Further, workaholism decreased during the career among members of the Exhausted-Workaholic profile suggesting positive direction during caree…

Influence of Nanoparticle Exposure on Nervous System Development in Zebrafish Studied by Means of Light Sheet Fluorescence Microscopy

2016

Zebrafish has a remarkable similarity in the molecular signaling processes, cellular structure, anatomy and physiology to other higher order vertebrates, making it an excellent vertebrate model organism (1). Recently, zebrafish has been used for neurotoxicity screening of numerous nanomaterials with a focus on the developmental effects due to the possibility of in vivo visualization of specific neurons and axon tracts by injecting dyes in live animals as well in fixed ones (2). Here we propose Light Sheet Fluorescence Microscopy (LSFM) (3) (4) to perform neurotoxicity studies, in order to study the nervous system architecture and to image 3D structures in the brain of live larvae during the…

Effectuation Logic in Digital Business Model Transformation : Insights from Japanese High-Tech Innovators

2019

Purpose The purpose of this paper is to study how digital business models evolve when entrepreneurs move to new digital platforms and how this evolution is related to effectuation and causation logics. Design/methodology/approach This study applies a multiple case study approach to investigate how digital business models change in small, Japanese high-tech firms providing their innovations through different digital platforms. To investigate digital business models, this study considers the elements that comprise general business models. The case firms were selected based on size, products and transitions from physical to various digital platforms. Semi-structured interviews were conducted …

Thinking about industry decline : A qualitative meta-analysis and future research directions

2018

We analyze historical and longitudinal research focusing on industry decline. Our analysis suggests that the literature’s general reliance on a few meta-theoretical arguments has important consequences for how decline is framed and explained. We identify four meta-theoretical clusters in the literature: politics and market dynamics are seen as exogenous factors with deterministic features, whereas technology and management capabilities are framed as firm-internal failures with causally questionable explanations of how firm-level characteristics explain industry-level decline. We propose that it is important to understand the limitations of distinct meta-theoretical arguments for an enhanced…

Investing in strategic development : Management control of business model and managerial innovations

2018

Purpose This paper aims to explore management control in the strategic development of business model and managerial innovations. The issue is approached from the perspective of managerial work, aiming to outline what managers consider as essential elements of management control in these often iterative and learning-intensive developmental activities. Design/methodology/approach The study is based on the views of 20 managers engaged in strategic development and its control in various organisations. The interview data consist of the respondents’ experiences and project cases involving non-technological innovations. Qualitative content analysis is used to identify three key concepts of manage…

On a Robin (p,q)-equation with a logistic reaction

2019

We consider a nonlinear nonhomogeneous Robin equation driven by the sum of a \(p\)-Laplacian and of a \(q\)-Laplacian (\((p,q)\)-equation) plus an indefinite potential term and a parametric reaction of logistic type (superdiffusive case). We prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter \(\lambda \gt 0\) varies. Also, we show that for every admissible parameter \(\lambda \gt 0\), the problem admits a smallest positive solution.

Nie każdy nosił w plecaku buławę… hetmańską. Kilka uwag o karierze wojskowej i politycznej Aleksandra Hilarego Połubińskiego w związku z pracą Andrze…

2020

Celem artykułu recenzyjnego jest ocena biografii i Aleksandra Hilarego Połubińskiego pióra Andrzeja A. Majewskiego. Dokonano w nim analizy następujących jej elementów: wykorzystanej bazy źródłowej i literatury, właściwości doboru bohatera, konstrukcji pracy oraz postawionych w niej tez. W przypadku tych ostatnich największe zastrzeżenia wzbudziły: sposób przedstawienia Połubińskiego jako dowódcy wojskowego; sprowadzenie na dalszy plan rozważań jego kariery politycznej; zmarginalizowanie działalności gospodarczej; sposób przedstawienia klienteli Połubińskiego. W połączeniu z przyjętą konstrukcją pracy — chronologiczną, z nadmiernie rozbudowanymi opisami działań wojennych, obniża to ocenę rec…
