Paradoksi un maldīgi spriedumi statistikā
2021
Šajā darbā tiek aprakstīti vairāki paradoksi un maldīgie spriedumi statistikā, kurus ir būtiski izprast, lai izdarītu korektus secinājumus par datiem dažādās zinātnēs, piemēram, epidemoloģijā, tiesību zinātnē, sociālajās zinātnēs. Kaut arī liela daļa no šiem fenomeniem tika aplūkoti jau 20. gadsimtā, ar paradoksiem saistītie rezultāti vēl joprojām var būt intuitīvi nesaprotami, kaut arī no statistikas viedokļa tie ir korekti. Savukārt, maldīgie spriedumi, kuri var likties loģiski, bet noved pie nepareiza rezultāta, joprojām ir sastopami rakstos. Darbā fenomeni tiek aprakstīti un doti piemēri.
On Psychological Aspects about Electric Vehicles, Part 1
2021
The high diffusion of electric vehicles is evidenced by every sector magazine or by the catalog of all the manufacturers inserting incessantly new models. But what are the user's most hidden reactions to the new world of vehicles? Is the user ready for the fifth level of automation (fully automatic driving and absence of the driving position)? The purpose of this paper is to present and discuss the psychological aspects that influence the adoption of electric vehicles by users and beyond. Topics such as the egg and chicken paradox (electric vehicles and charging stations, who was born first) but also performance anxiety (range anxiety) will be addressed. Contradictions and irony will charac…
How paradoxical is ‘paradoxical’ outcome? : Different pathways and implications
2021
The present special issue includes single and multiple case studies which report on the phenomenon of ‘paradoxical’ outcomes in psychotherapy, operationalized as discordant outcome assessments within the same case. In an attempt to find ground for my published response, I endeavored to juxtaposition the cases from the different studies, and by doing that gain an overview of the contributions and arguments. As a result of that exercise, I suggest three different types of paradoxical outcome with different pathways and implications. Discussing the concept of ‘illusory mental health’ as a possible explanation for paradoxical outcome, I suggest that self-ratings within a nonclinical range, give…
Taylorism on steroids or enabling autonomy? A systematic review of algorithmic management
2023
AbstractThe use of algorithmic management systems is rapidly changing organizational models and practices, as millions of workers in multiple sectors worldwide are managed by computer software. Despite receiving increasing academic interest, little summarizing literature exist on the ways algorithmic systems are used in management. This article aims to fill this gap by systematically reviewing and qualitatively analyzing 172 articles on the topic. Our research contributes to the existent algorithmic management literature in three ways. First, we provide a descriptive overview of algorithmic management as a field of research. Second, we identify and synthesize the discussion on the key conce…
The complexity of knowledge construction in a classroom setting
2018
International audience; We study a class of mathematics education MA students in an introductory course on Chaos and Fractals, as they grapple with the Sierpinksi triangle, and in particular with the apparent paradox that its area equals 0, while its perimeter is infinitely long. For this purpose, we network an approach for investigating the construction of knowledge in small groups with one for examining how ideas and ways of reasoning function-as-if-shared in a classroom. Our results show complexities: (i) small group work and whole class discussions mutually influence each other; (ii) ideas may function-as-if-shared in the whole class even if the majority of students have not previously …
Distributed Leadership and the Visibility/Invisibility Paradox in On-line Communities
2011
This paper analyzes the role of distributed leadership in three on-line communities, reflecting on an observed visibility/invisibility paradox in leadership within these communities. Leaders who downplay their seniority and assume a degree of invisibility, allocating discretionary powers to subordinate levels in an organizational hierarchy, may facilitate the emergence of distributed leadership. Yet, simultaneously, leader-led relations are enabled by high leadership visibility. This paradox—that leaders need to be both highly visible and also invisible, or hands-off, when the occasion requires it—was derived from prior research into e-learning communities and tested in the analysis of disc…
Correlation Between Smoking Paradox and Heart Rhythm Outcomes in Patients With Coronary Artery Disease Receiving Percutaneous Coronary Intervention
2022
BackgroundThe effect of smoking on short-term outcomes among patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) is controversial. However, little is known about the impact of smoking on long-term outcomes in patients with stable coronary artery disease (CAD) who receive PCI.MethodsA total of 2,044 patients with stable CAD undergoing PCI were evaluated. They were divided into two groups according to smoking status (current smokers vs. non-smokers). Baseline characteristics, exposed risk factors, angiographic findings, and interventional strategies were assessed to compare the long-term clinical outcomes between groups. Predictors for myocardial in…
Compensated transfer entropy as a tool for reliably estimating information transfer in physiological time series
2013
We present a framework for the estimation of transfer entropy (TE) under the conditions typical of physiological system analysis, featuring short multivariate time series and the presence of instantaneous causality (IC). The framework is based on recognizing that TE can be interpreted as the difference between two conditional entropy (CE) terms, and builds on an efficient CE estimator that compensates for the bias occurring for high dimensional conditioning vectors and follows a sequential embedding procedure whereby the conditioning vectors are formed progressively according to a criterion for CE minimization. The issue of IC is faced accounting for zero-lag interactions according to two a…
The paradox of the Italian clinical embryologist in the national public health system: hints towards harmonization of a postgraduate educational curr…
2022
Clinical embryologists are highly trained laboratory professionals with multiple roles, including laboratory, clinical, biobanking and quality system management. In most European countries, clinical embryologists are trained to work in Medically Assisted Reproduction (MAR) centres without a specifically dedicated educational path. The criteria required for employment vary according to the educational structure and the public or private nature of the centre. We have herein described the educational profile required by Italian clinical embryologists to work in MAR centres of the National Health System (NHS). Public centres currently represent 36% of all the Italian MAR clinics. According to t…
Nickel release after implantation of the Amplatzer occluder.
2003
Background Transcatheter closure of atrial septal defects is a new and less traumatic technique than open heart surgery. In recent years, patients with a patent foramen ovale sustaining potential paradoxical embolism have also become candidates for interventional closure devices. One of the more popular occluding devices is the Amplatzer septal occluder, which, like many other occluders, is made of nitinol. Nitinol-based alloys are widely used in medical products, for example, in orthopedics and orthodontics. However, the clinical use of nitinol, which contains 55% nickel, is still controversial because of concerns about its biocompatibility. Therefore, we examined the systemic nickel relea…
