Effects of postharvest partial dehydration and prolonged treatments with ethylene on transcript profiling in skins of wine grape berries.
2010
For certain food products, postharvest controlled stresses or treatments with specific elicitors are applied to induce desired physical/chemical changes and/or to positively affect phytochemical content. This is the case of wine grapes where both strategies, singularly applied or coupled, can be used to modulate berry composition and, as a consequence, affect wine quality traits. Since the knowledge of the effects of these postharvest treatments on berry metabolism and the regulation of gene expression is very limited, a large-scale transcriptome analysis has been carried out, using an oligo-based microarray (14,562 probes) on skins of wine grape (Vitis vinifera L.) berries subjected to deh…
Nad kartami prac profesora Witolda Mańczaka. Notatki z marginesów
2017
In the works written in the last period of his life, Professor Witold Mańczak often emphasized the need to formulate a criterion of truth in linguistics. He pursued it in textual reality (in “what is written and what is said”) and in statistical, frequentative and quantitative data which describe it. On the margin of this search, this author shares his own experiences in the field of ethnolinguistics, related to attempts to determine the actual (and, in this sense, true) ontological status of analyzed objects. He postulates that the diversification of the objects of analysis should be complemented by an adequate diversification of how their names are recorded in the narration, i.e. by a pre…
Multi-scale optimisation vs. genetic algorithms in the gradient separation of diuretics by reversed-phase liquid chromatography
2019
Abstract Multi-linear gradients are a convenient solution to get separation of complex samples by modulating carefully the gradient slope, in order to accomplish the local selectivity needs for each particular solute cluster. These gradients can be designed by trial-and-error according to the chromatographer experience, but this strategy becomes quickly inappropriate for complex separations. More evolved solutions imply the sequential construction of multi-segmented gradients. However, this strategy discards part of the search space in each step of the construction and, again, cannot deal properly with very complex samples. When the complexity is too large, the only valid alternative for fi…

Job Characteristics, Recovery Experiences and Occupational Well-being: Testing Cross-lagged Relationships across 1 Year
2013
The aim of the present study conducted among 274 Finnish employees was to examine the relationships between job characteristics, recovery experiences and occupational well-being across 1 year. We hypothesized that these relationships would follow normal causation, that is, job characteristics at T1 predict recovery experiences (detachment, relaxation, mastery and control at off-job time) and well-being (fatigue at work and work engagement) at T2, and recovery experiences at T1 predict well-being at T2. The structural equation modelling analyses lent support to the hypothesized normal causation model compared with the reversed causation and reciprocal models. However, only the longitudinal r…
RNACache: Fast Mapping of RNA-Seq Reads to Transcriptomes Using MinHashing
2021
The alignment of reads to a transcriptome is an important initial step in a variety of bioinformatics RNA-seq pipelines. As traditional alignment-based tools suffer from high runtimes, alternative, alignment-free methods have recently gained increasing importance. We present a novel approach to the detection of local similarities between transcriptomes and RNA-seq reads based on context-aware minhashing. We introduce RNACache, a three-step processing pipeline consisting of minhashing of k-mers, match-based (online) filtering, and coverage-based filtering in order to identify truly expressed transcript isoforms. Our performance evaluation shows that RNACache produces transcriptomic mappings …
Educational Perspectives on Scripting CSCL
2007
This chapter discusses different educational approaches to collaboration scripts. When carefully designed, scripts can push learners to that kind of situations in which meaningful interaction can take place. However, many conditions need to be met for this to happen in authentic classroom contexts. One of the biggest educational challenges in instructional design of computer-supported collaboration scripts is to better integrate them into wider social planes such as overall classroom activities. Scripts could also be considered as contextual and situated resources in collaborative learning environments. Furthermore, a challenge for future research is to explore how external scripts can be g…
Role Scripting as a Tool to Foster Transactivity of Asynchronous Student Discussions
2021
Transactivity of student discussions is crucial in computer-supported collaborative learning (CSCL). However, CSCL learners often lack well-developed argumentation and negotiation skills, which makes it challenging for them to engage in and maintain a transactive discussion. Collaboration scripts have been implemented in CSCL contexts and have demonstrated positive effects on students' collaboration and argumentation skills. Yet, the degree of transactivity of student interactions is rarely addressed directly in CSCL research. Employing a qualitative content analysis approach, this study seeks to understand how a role script affects the transactivity of students' argumentative knowledge co-…
Scripting Computer-Supported Collaborative Learning
2010
In this chapter, we will present a review of theoretical and empirical analyses of Web-based collaboration processes used during a scripted university course. The results refer to a design-based study that involved first-year teacher-education students (N = 30) studying pedagogy over a period of three months. The intervention involved structuring the subjects’ collaborative actions with three different pedagogical scripts. According to the findings, the scripts guided students’ activities by helping them find resources for knowledge construction and work together through a series of steps. However, there were variations among groups in terms of quality of collaboration, and the students mos…
Security Implications of Using Third-Party Resources in the World Wide Web
2018
Modern web pages have nothing in common with the static connotation coming from the word “page” - it is a dynamic unique experience created by active content and executed within browser, just-in-time assembled from various resources hosted on many different domains. Active content increases attack surface naturally exposing users to many novel threats. A popular security advice has been to deploy active content blocker plugins like NoScript, unfortunately they are not capable to effectively stop the attacks. Content Security Policy (CSP) can be effective against these attacks, but we demonstrate how poor decisions made by website administrators or external resource hosters can render CSP in…
