qEEG Analysis in the Diagnosis of Alzheimers Disease; a Comparison of Functional Connectivity and Spectral Analysis

Alzheimers disease (AD) is a brain disorder that is mainly characterized by a progressive degeneration of neurons in the brain, causing a decline in cognitive abilities and difficulties in engaging in day-to-day activities. This study compares an FFT-based spectral analysis against a functional connectivity analysis based on phase synchronization, for finding known differences between AD patients and Healthy Control (HC) subjects. Both of these quantitative analysis methods were applied on a dataset comprising bipolar EEG montages values from 20 diagnosed AD patients and 20 age-matched HC subjects. Additionally, an attempt was made to localize the identified AD-induced brain activity effects in AD patients. The obtained results showed the advantage of the functional connectivity analysis method compared to a simple spectral analysis. Specifically, while spectral analysis could not find any significant differences between the AD and HC groups, the functional connectivity analysis showed statistically higher synchronization levels in the AD group in the lower frequency bands (delta and theta), suggesting that the AD patients brains are in a phase-locked state. Further comparison of functional connectivity between the homotopic regions confirmed that the traits of AD were localized in the centro-parietal and centro-temporal areas in the theta frequency band (4-8 Hz). The contribution of this study is that it applies a neural metric for Alzheimers detection from a data science perspective rather than from a neuroscience one. The study shows that the combination of bipolar derivations with phase synchronization yields similar results to comparable studies employing alternative analysis methods.

MULTIPLE CRITERIA DECISION MAKING ANALYSIS OF THE PORT OF ŠVENTOJI DEVELOPMENT

Port of Šventoji is a maritime facility in the settlement of Šventoji, located within the country Lithuania, near the seaside resort town of Palanga. In this paper five Port of Šventoji development alternatives are overviewed using a multi-criteria decisionmaking (MCDM) method. The results will be compared with the ones found in “Port of Šventoji reconstruction feasibility study” (liet. Šventosios jūrų uosto atstatymo galimybių studija). Criteria weights of the analysed alternatives are determined using the entropy method. Alternative analysis is carried out using the TOPSIS multicriteria method.

Industry 4.0: A Proposal of Paradigm Organization Schemes from a Systematic Literature Review

Currently, the concept of Industry 4.0 is well known; however, it is extremely complex, as it is constantly evolving and innovating. It includes the participation of many disciplines and areas of knowledge as well as the integration of many technologies, both mature and emerging, but working in collaboration and relying on their study and implementation under the novel criteria of Cyber–Physical Systems. This study starts with an exhaustive search for updated scientific information of which a bibliometric analysis is carried out with results presented in different tables and graphs. Subsequently, based on the qualitative analysis of the references, we present two proposals for the schematic analysis of Industry 4.0 that will help academia and companies to support digital transformation studies. The results will allow us to perform a simple alternative analysis of Industry 4.0 to understand the functions and scope of the integrating technologies to achieve a better collaboration of each area of knowledge and each professional, considering the potential and limitations of each one, supporting the planning of an appropriate strategy, especially in the management of human resources, for the successful execution of the digital transformation of the industry.

An ‘Organ of Student Opinion’? Alternative Print, Protest, and the Politics of Education in Salient, 1973-1989

<p>This thesis explores Victoria University of Wellington’s student newspaper, Salient, in the 1970s and 1980s. Salient covered a wide array of issues, performing its role as a campus newspaper while closely engaging with and informing students of wider political issues during a period of significant student protest. As a publication, it consistently and deliberately set itself apart from the mainstream media, a position which placed it alongside other alternative or radical publications. Furthermore, the thesis demonstrates that the connections between Salient and the Wellington Marxist-Leninist Organisation (MILO) were profound and enduring in the 1970s, with significant implications for the kinds of analysis and issues that Salient presented to its readers. While individual editors did have unique editorial policies, the nature of Salient’s journalism in the 1970s was notably socialist and activist in its outlook. In the 1980s, while Salient maintained a progressive political outlook, the direct association with MILO (by then the Workers’ Communist League) loosened. The paper’s political content still covered a range of contemporary social issues, and its editors took political stances, but its content was more akin to political commentary than an extension of political activism. The exception was Salient’s opposition to user pays tertiary education, which was seriously considered by David Lange’s Labour Government as part of its neoliberal reforms. As the possibility of a user-pays tertiary education system became more likely, Salient dedicated more space to covering, opposing, and organising action against this disruptive policy which had major implications for its student readership. Salient often did not speak for all students, but provided a platform for alternative analysis of social and political issues, pushing the boundaries of the purpose of student media and its place within the print landscape of New Zealand.</p>

A social media-based framework for tourist behaviour analysis and characterization in urban environments

Tourism is a very important and fast growing industry worldwide that has generated 25% of all global net new jobs during the last 5 years. New tools can be valuable for relaunching the sector and provide alternative analysis and segmentation capabilities to organizations involved. We present an analysis and visualization framework for tourist behaviour study and segmentation based on tested methods and technologies, combined and extended in an innovative way. Our framework uses Flickr data as input and classifies users according to country of origin. Then, urban distribution patterns are obtained in two different spatial levels by using [Network] Kernel Density Estimation in 1D and 2D spaces, as well as spatial clustering with HDBSCAN. Basic Natural Language Processing is applied to extract and visualize semantics generated in the social media platform and a visualization of typologies of Points of Interest by nationality is proposed for the development of tourism dashboards. We have applied our framework to three European cities of different size to test the segmentation capabilities of the approach. Results suggest a good potential for tourism management in urban environments.

New Perspectives on the Urban–Rural Dichotomy and Dialect Contact in the Arabic gələt Dialects in Iraq and South-West Iran

This paper reevaluates the ground on which the division into urban and rural gələt dialects, as spoken in Iraq and Khuzestan (south-western Iran), is built on. Its primary aim is to describe which features found in this dialect group can be described as rural and which features tend to be modified or to emerge in urban contexts, and which tend to be retained. The author uses various methodical approaches to describe these phenomena: (i) a comparative analysis of potentially rural features; (ii) a case study of Ahvazi Arabic, a gələt dialect in an emerging urban space; and (iii) a small-scale sociolinguistic survey on overt rural features in Iraqi Arabic as perceived by native speakers themselves. In addition, previously used descriptions of urban gələt features as described for Muslim Baghdad Arabic are reevaluated and a new approach and an alternative analysis based on comparison with new data from other gәlәt dialects are proposed. The comparative analysis yields an overview of what has been previously defined as rural features and additionally discusses further features and their association with rural dialects. This contributes to our general understanding of the linguistic profile of the rural dialects in this geographic context.

Polish Deadjectival Nouns as Nominalized Adverbs

Wedle tradycyjnego opisu, polskie abstrakcyjne rzeczowniki odprzymiotnikowe (nomina essendi), takie jak np. lekkość czy jasność, są zbudowane z przymiotnikowego tematu i przyrostka -ość. Artykuł rozważa alternatywną analizę, wedle której -o-ść jest przyrostkiem złożonym, a tworzone z nim rzeczowniki odprzymiotnikowe przechodzą przez etap przysłówkowy, czyniąc je formami o strukturze [[[ A ] Adv ] N ]. Możliwość złożoności -o-ść sugeruje fakt, że -o jest przyrostkiem tworzącym przysłówki. ABSTRACT The traditional description of Polish abstract nouns such as lekkość‘ lightness’or jasność ‘brightness’ holds that they are formed with an adjectival root and the nominalizing suffix -ość. The paper considers an alternative analysis where -o-ść is a complex marker and such nominals go through an adverbial stage in their formation, rendering them [[[ A ] Adv ] N ] structures, a possibility suggested by the fact that the -o itself is an adverbial marker.
