Sentiment Analysis, Quantification, and Shift Detection

This dissertation focuses on event detection within streams of Tweets based on sentiment quantification. Sentiment quantification extends sentiment analysis, the analysis of the sentiment of individual documents, to analyze the sentiment of an aggregated collection of documents. Although the former has been widely researched, the latter has drawn less attention but offers greater potential to enhance current business intelligence systems. Indeed, knowing the proportion of positive and negative Tweets is much more valuable than knowing which individual Tweets are positive or negative. We also extend our sentiment quantification research to analyze the evolution of sentiment over time to automatically detect a shift in sentiment with respect to a topic or entity. We introduce a probabilistic approach to create a paired sentiment lexicon that models the positivity and the negativity of words separately. We show that such a lexicon can be used to more accurately predict the sentiment features for a Tweet than univalued lexicons. In addition, we show that employing these features with a multivariate Support Vector Machine (SVM) that optimizes the Hellinger Distance improves sentiment quantification accuracy versus other distance metrics. Furthermore, we introduce a mean of representing sentiment over time through sentiment signals built from the aforementioned sentiment quantifier and show that sentiment shift can be detected using geometric change-point detection algorithms. Finally, our evaluation shows that, of the methods implemented, a two-dimensional Euclidean distance measure, analyzed using the first and second order statistical moments, was the most accurate in detecting sentiment shift.
Power of Random Choices Made Efficient for Fog Computing

In this article, we consider a load balancing protocol based on the power of random choices that is adapted to a fog deploy in which several independent fog nodes equipped with a set of servers or VM are serving the same geographical area. The protocol is based on a simple but effective mechanism based on a threshold <inline-formula><tex-math notation="LaTeX">$T$</tex-math><alternatives><mml:math><mml:mi>T</mml:mi></mml:math><inline-graphic xlink:href="beraldi-ieq1-2968443.gif"/></alternatives></inline-formula>. When a fog node receives a unit of computation or a job, it immediately executes the job if the number of its occupied servers is lower than <inline-formula><tex-math notation="LaTeX">$T$</tex-math><alternatives><mml:math><mml:mi>T</mml:mi></mml:math><inline-graphic xlink:href="beraldi-ieq2-2968443.gif"/></alternatives></inline-formula>, otherwise the node executes a randomized algorithm by probing <inline-formula><tex-math notation="LaTeX">$F$</tex-math><alternatives><mml:math><mml:mi>F</mml:mi></mml:math><inline-graphic xlink:href="beraldi-ieq3-2968443.gif"/></alternatives></inline-formula> other fog nodes in the area, and delegates the execution of the job to the least loaded one, provided the workload is lower than the probing node. Through a mathematical analysis we show that probing just one node (<inline-formula><tex-math notation="LaTeX">$F=1$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>F</mml:mi><mml:mo>=</mml:mo><mml:mn>1</mml:mn></mml:mrow></mml:math><inline-graphic xlink:href="beraldi-ieq4-2968443.gif"/></alternatives></inline-formula>) when there are less than two free VMs provides the same performance of the well known power-of-two random choices centralized algorithm, but at a much lower delay and control overhead costs. Also, simulations are used to address the node heterogeneity and, with a real testbed, we offer results that prove the effective benefit of the proposed solution in practical applications.
On the Numerical Solution of Ordinary, Interval and Fuzzy Differential Equations by Use of F-Transform

An interesting property of the inverse F-transform f ^ of a continuous function f on a given interval [ a , b ] says that the integrals of f ^ and f on [ a , b ] coincide. Furthermore, the same property can be established for the restrictions of the functions to all subintervals [ a , p k ] of the fuzzy partition of [ a , b ] used to define the F-transform. Based on this fact, we propose a new method for the numerical solution of ordinary differential equations (initial-value ordinary differential equation (ODE)) obtained by approximating the derivative x · ( t ) via F-transform, then computing (an approximation of) the solution x ( t ) by exact integration. For an ODE, a global second-order approximation is obtained. A similar construction is then applied to interval-valued and (level-wise) fuzzy differential equations in the setting of generalized differentiability (gH-derivative). Properties of the new method are analyzed and a computational section illustrates the performance of the obtained procedures, in comparison with well-known efficient algorithms.
GENOTYPING OF LISTERIA MONOCYTOGENES IN IRAQI WOMEN WITH SPONTANEOUS ABORTION USING PULSE FIELD GEL ELECTROPHORESIS

Background: Listeria monocytogenes (L. monocytogenes) is a Gram-positive, facultative intracellular bacterial pathogen that can cause a severe invasive disease (listeriosis) mainly in pregnant women. Based on genetic content, L. monocytogenes can be divided into 3 lineages I, II and III. Several molecular methods have been developed to assist in the characterization of L. monocytogenes, macrorestriction analysis by pulse-field gel electrophoresis (PFGE) is one of the most used methods for the genotyping of L. monocytogenes. Objective: To determine the predominant genotype of L. monocytogenes isolated from clinical cases in a group of aborted Iraqi women. Methods: A study was designed and included 15 clinical isolates of L. monocytogenes and one isolate from locally made cheese. The PFGE protocol was performed as described by Graves and Swaminathan. Briefly, bacterial suspensions adjusted to optical density of 1.3 at 610 nm were embedded in 1.2% Sea Kem Gold agarose plugs. The lysed, washed five times and a 2 mm thick piece was cut, equilibrated and digested with 200 μl of AscI enzyme master mix at 37 °C for 2 h. The macrorestriction fragments were separated by electrophoresis on a CHEF-DRIIBIO-RAD. Images were analyzed with the software Bio Numerics Gel Compar II version 6.6. 11 (Applied Maths). Results: All L. monocytogenes isolates displayed AscI digestion profiles after incubation with the enzyme, about 6-12 majorfragments of 30 to 675 kb were obtained, sixteen isolates have been used in this study, however, 11 different AscI profiles were encountered, the distribution of the isolates according to the restriction profiles showed that two profiles were the most predominant A, A2 with a percentage of similarity of 100%. Conclusion: L. monocytogenes genotyping showed profiles that can be well used in tracing down infection source and outbreak of this bacterium. PFGE represents a great discrimination and reproducibility method for molecular sub-typing of L. monocytogenes and it is considered the gold standard.

Direct Measurement of Rates of Asymptomatic Infection and Clinical Care-Seeking for Seasonal Coronavirus

The pandemic potential of the novel coronavirus (nCoV) that emerged in Wuhan, China, during December 2019 is strongly tied to the number and contagiousness of undocumented human infections. Here we present findings from a proactive longitudinal sampling study of acute viral respiratory infections that documents rates of asymptomatic infection and clinical care seeking for seasonal coronavirus. We find that the majority of infections are asymptomatic by most symptom definitions and that only 4% of individuals experiencing a seasonal coronavirus infection episode sought medical care for their symptoms. These numbers indicate that a very high percentage of seasonal coronavirus infections are undocumented and provide a reference for understanding the spread of the emergent nCoV.
Neck Strength-endurance Assessment: Potential Utility in Sport-related Concussion

Neck strength may modify the risk of sport related concussion by controlling head acceleration during high risk impacts. The majority of literature evaluates maximal neck strength leaving other parameters less-explored. Thus, the purpose of this study was to assess neck strengthendurance in male and female athletes. We hypothesized: (1) females would perform poorer on the neck assessment compared to males; (2) athletes with a history of concussion would perform poorer than those with no history of concussion. Neck strength-endurance (flexion, extension, left and right flexion) was assessed in ninety-seven (n = 97) interuniversity athletes. The majority (68%) of participants failed one or more directions of the neck assessment, and most often in flexion (38%) and bi-lateral flexion (33%). There were no significant differences in neck strength-endurance between participants with and without history of concussion or between sexes. These results support assessing neck parameters in an attempt to reduce direction-specific deficits.
Food Loss and Waste, a global responsibility?!

Food loss and waste remains a big academic and policy concern all over the world. Reduction of flw is one of the ways to enhance the food quality and security as well as environmental sustainability and economic wellbeing. The aim of the article is to tackle the issue of the flw and investigate the results that derive from worldwide implemented projects and strategies. To do so, the paper brings together the findings of the main fieldworks related to the flw issue categorizing them along the several phases of the food supply chain: harvesting, processing, storage, transportation and consumption. Besides the analysis of academic literature on the topic, we have collected and described several good practical cases and initiatives related to flw problem carried out similarly to the results of the authors cited in the theoretical part of the paper. Findings show our point of view on the importance of optimal and sustainable use of resources, as well as the ways through which food related expenditures can be reduced. An aware, bottom-up and crosssectional approach appears to be crucial for facing this global issue and for making it more manageable over time.
DEFENSIVE ROLE OF NITRIC OXIDE (NO) UNDER DROUGHT STRESS IN PLANTS: MINI-REVIEW

There are several physiological implications of Nitric oxide (NO) gas have been reported so far in plants. Among these protection of plants from various abiotic and biotic stresses are gaining attention on priority. Presently, drought stress is the most prevalent abiotic stress in plants that affects their growth, development and overall yield. The role of NO in resisting drought stress has been investigated by many researchers. But it is still unclear about the actual involvement of NO in drought stress responses at a whole plant level. This article reviews the defensive role of NO during drought stress in plants.

Passive flutter suppression of damaged smart laminated composite plate using active fiber composite layer

Abstract This research addresses the effect of damage on flutter characteristics of laminated composite plate and passive control of flutter with active fiber composite (AFC) layer bonded over the substrate. A finite element model coupled with MSC.Nastran is developed to calculate the flutter characteristics of smart laminated composite plate. The damage characterized based on anisotropic damage formulation is incorporated through the finite element model. The effect of orientation and location of damage on flutter characteristics of laminated plate is studied. Further AFC layer with interdigitated electrode, which is more adaptive and efficient than conventional monolithic piezoelectric, is considered over the top of substrate layer to act as actuator. The enhancement of the flutter characteristics lost due to damage, is investigated by activating AFC layer with applied voltage. The AFC layer is observed to have great potential to regain the flutter strength of composite plate. Communicated by Chandrika Prakash Vyasarayani.
Urbanismo de resistencia en Puerta de Tierra. II Workshop de Arquitecturas Colectivas

The collective “taller Creando Sin Encargos”, composed by professors of architecture, has as mission to develop projects that support self-management initiatives in communities in Puerto Rico. The II Workshop: Collective Architectures in Puerta de Tierra, San Juan, supports the work of two artists, residents and community leaders who reacted to the effects of gentrification in their community calling themselves “Brigada PDT”. The “Brigada” rescued abandoned structures by cleaning and painting murals with messages that call for inclusive public spaces. As part of an exercise in participatory design and construction, the Workshop participants, students of architecture and other disciplines should draw inspiration from the work of artists and the daily acts of the inhabitants to intervene one of the structures rescued and converted into a “Plaza Vivero”. Consequently, they had to correct the deficiencies in the urban space that affect these acts. Taking as a starting point the placemaking, the intervention had to be inserted organically as part of the environment and the natural movement of passers-by and residents, but also becoming an icon of urbanism of resistance to developments that do not correspond to the social reality of the place.
Estimating Parameters of Structural Models Using Neural Networks

Machine learning tools such as neural networks see increasing applications in marketing and economics for predictive tasks, such as classifying images and forecasting choices. Instead of these predictive tasks, we explore using neural nets to estimate the parameter values for an economic model. The neural net is trained with model-generated datasets. Through training, the neural net learns a direct mapping from (the moments of) a dataset to the parameter values under which the dataset is generated. We show this Neural Net Estimator (NNE) converges to Bayesian parameter posterior when the number of training datasets is sufficiently large. We examine the performance of NNE in two Monte Carlo studies. NNE incurs substantially smaller simulation costs compared to simulated MLE and GMM, while achieving no worse estimation accuracy. NNE is also easy to implement with the wide availability of neural net training packages.
An integrated system of engaging social workers and community volunteers in social care for the elderly: case studies in Taiwan

Abstract Integrating volunteers into social care is widely expected but rarely successful in practice. This paper discusses how the Community Care Centre Plan organising community volunteers to provide services to the elderly in Taiwan. This plan successfully integrated social workers and volunteers in a national system to offer service in local communities, showing a systemic practice of community care and a unique case of community-based and volunteer-based service. The purposes of this paper are to introduce the programme design and to understand how to integrate the mission of social workers and volunteers’ performance. The governmental policy and requirements, the role of social workers and the provision of voluntary community service which contributed to form the system were examined in this paper.
Electronic Customer Relationship Management in Tourism

Tourism companies, like other companies producing goods and/or services, practice different strategies to achieve competitive advantage and satisfy the needs and wants of customers/guests. The most important recent strategy is electronic customer relationship management (e-CRM). In today's competitive environment, a successfully implemented e-CRM enhances a customer centric culture that is key to tourism growth and competitive advantage. For tourism companies, e-CRM succeeds only if it is totally integrated strategically and operationally in the business and in the information system of the company. This chapter focuses on e-CRM concept, its importance in tourism, dimensions of e-CRM, major challenges of e-CRM and its opportunities for companies, its implementation in tourism, e-CRM Technologies used in tourism, e-CRM success factors, and the reasons of e-CRM failures.
Dynamic Crosstalk-Cancellation with Room Compensation for Immersive CAVE-Environments

Auralization of virtual scenes using binaural synthesis enables a realistic reproduction of auditory events, which provides the feeling of immersion in Virtual Reality applications. Headphones are usually used with binaural synthesis; however, they tend to constrain the users immersion. To retain the immersion, a loudspeaker setup with a preceding Crosstalk-Cancellation (CTC) filter can be used. In large CAVE-VR-Systems with acoustically hard projection surfaces, which partly or completely surround the user, challenging acoustical conditions are to be expected. Not only is the speaker’s placement limited to positions above the hard projection surfaces but furthermore, due to the non-absorbent surfaces, distinct early reflections superimpose the useful signal. This results in a significant change in the overall reverberation time. Therefore a CTC filter design is proposed which compensates those early reflections. Based on the room geometry, sound transmission paths can be estimated. These estimations can then be used to integrate early reflections into the design of a dynamic CTC-system and lead to an improved playback quality for rooms with challenging acoustical conditions. The proposed algorithm shows promising results in it’s theoretic evaluation while measurements in the aixCAVE reveal a discrepancy in CTC quality between calculated channel separation and subjective perception.
Father of the Bride, or the Biologization of Social Animosity in Nazi Germany, 1937–1941*

In 1937, to his great dismay, Nazi ethnologist Otto Reche discovered that his daughter’s suitor came from a family ‘hereditarily burdened’ with mental diseases. A strong proponent of eugenics, Reche was determined to thwart the looming wedding. He turned to the highest authority on such matters, genetic-psychiatrist Ernst Rüdin, and asked him to furnish the evidence that the planned marriage was biologically undesirable. Reche’s daughter, however, was resolute in her choice, and the familial dispute soon escalated to involve the highest echelons of the Nazi state. A detailed micro-historical reconstruction of the affair exposes the way in which racial-hygienic doctrine, class resentment, inter-generational conflict and personal animosity became interwoven in the daily lives—and loves—of Germans under the Nazi regime.

c14bazAAR: An R package for downloading and preparing C14 dates from different source databases

Radiocarbon dating is one of the most important methods for absolute and relative chronological reconstruction of cultural development in prehistoric archaeology (Taylor & Bar-Yosef, 2016). This is true for the intrasite level, for regional comparisons and also in cases, where processes that have a large spatial and temporal reach are to be investigated. Prominent examples for the latter include the ‘neolithization’ of Europe or the ‘Bantu expansion’ in subSaharan Africa. They have been extensively analysed with radiocarbon data (e.g. Ammerman & Cavalli-Sforza (1971), Garcin et al. (2018), Jerardino, Fort, Isern, & Rondelli (2014), Lemmen, Gronenborn, & Wirtz (2011), Oslisly et al. (2013), Pinhasi, Fort, & Ammerman (2005), Russell, Silva, & Steele (2014), Weninger et al. (2009)).
