Using University Library Collections in Teaching
Authors: Rowley Joshua Larkin
Published: October 2022

Abstract: One way scholars research advertising’s history and place in society and culture is through the study of archival materials. Some universities and organizations have preserved documents and objects for scholars and students to use in their research and learning about advertising. This Advertising in the Classroom article discusses how Duke University’s John W. Hartman Center for Sales, Advertising & Marketing History makes its archival collections available for teaching. Joshua Larkin Rowley, one of the Hartman Center’s reference archivists, talks about how he works with faculty to make library collections a central part of students’ learning experience. He shares more about how he uses university library collections to facilitate classes and research workshops. He also gives advice on how instructors can work closely with librarians and archivists to inspire students to be excited about conducting archival research in person.
Burning Out Like Dying Stars: Why Agencies Need to Build More Supportive Work Environments for Women in Advertising
Authors: Tackett Teresa
Published: October 2022

Abstract: Women’s engagement is examined in an advertising agency setting as related to the agency’s leadership, culture, and workplace processes. Inductive analysis found that participants reported fluctuating levels of engagement over time, with the lowest levels of engagement cited during times of overwork or a lack of trust in the leadership team due to receding communication. The results demonstrate the key role agency culture and expectations plays in determining levels of workplace engagement, which is imperative for the recruitment and retention of talent in the advertising industry.

A technology-enhanced scaffolding instructional design for fully online courses
Authors: Yang Juan , Jiang Rui , Su Han
Published: October 2022

The COVID-19 pandemic has forced teachers to implement fully online teaching. This study reviewed the popular technologies that are used in online learning, as well as the advantages and difficulties of applying fully online courses for formal education. Based on this research background, this study proposed a nested scaffolding design of an online course for 215 college students in China with the help of six technological tools, which effectively replaced face-to-face interactions and significantly improved the usage of the supporting learning platform. The inner-outer learning cycles supported by the technological tools improved the quality of the scaffolding conversations, reduced the scaffolding time cost that teachers had to expend and enhanced the effectiveness of the individualised scaffolding instructions.
Implications for practice or policy:

First-year students’ learning outcomes can be improved by the scaffolding support from Web 2.0 resource URLs, a small private online course, and EducCoder resources.
Course leaders should construct at least 3–5 stage-wise evaluations to deconstruct the big learning process into several observable learning cycles, making the Kolb (1984) cycles controllable.
Assessors may need to consider involving various exercises, such as quizzes, online experiments and synthesised tasks to facilitate students’ learning.
CIDADE MENOR E A MAIS ALTA POTÊNCIA DO FALSO
Authors: Vieceli Ana Paula , Lanius Eduardo
Published: November 2022

Este ensaio trata da cidade menor como uma outra cidade dentro da cidade. Da cidade intensiva que se insinua dentro da realidade conceitual ou material da cidade enquanto produto do planejamento ou das forças e valores de mercado. Na busca por vivências e práticas singulares, apresenta Nova Bréscia como cidade pequena, fronteiriça com o campo, que inventa e cultiva um festival para contar mentiras, reunir a comunidade e fazer delirar a colônia. Durante três dias, a cidade inverte os valores subjetivados pela moral servil do trabalho, e transforma o discurso da escassez em abundância a partir de um desvio lúdico e bem-humorado. O ensaio responde ao Festival da Mentira e, inspirado nele, toma a forma de um grande embuste acadêmico, no qual se reflete acerca da arte, junto a Nietzsche e Deleuze, como a mais alta potência do falso.
SOBRE VIVER
Authors: Oliveira Buchebuan Terezinha , Signori Luiza, , Rettore Manuela , Rossini dos Santos Maurício
Published: November 2022

Buscar um urbanismo incorporado que reconheça os muitos sujeitos que habitam o espaço é quebrar o consenso do espetáculo urbano. No conjunto de forças que definem as localizações na cidade, são os grupos sociais excluídos que, na escassez, resistem ao se apropriar do espaço, tempo, obra e festa. Resistir é tensionar através do corpo. É desviar do esperado. O presente trabalho, a partir de outros autores, reflete sobre o papel de arquitetas(os) e urbanistas na (trans)formação dos espaços do cotidiano. Chama atenção a necessidade de uma forma de atuar mais sensível aos conflitos e as diferentes formas de viver a urbanidade. Olhar para as muitas cidades dentro de uma, observar os movimentos ordinários e os espaços menores dos praticantes de cidade é não deixar apagar o protagonismo das comunidades, vilas e favelas. Conclui-se que é no olhar atento às complexidades da vida que poderemos encontrar caminho para uma cidade outra.

Authors: Lindner Natália , Lazzarotto Modler Nébora
Published: November 2022

As bibliotecas públicas são equipamentos essenciais para fomentar o desenvolvimento sociocultural, principalmente em cidades pequenas e médias, onde há carência de alternativas voltadas ao lazer e à cultura. No entanto, as instalações das bibliotecas são usualmente precárias, o que compromete a qualidade do serviço oferecido. Além disso, a leitura não é incentivada de maneira efetiva, e muitas vezes não é identificada como prática útil e agradável. O mesmo fenômeno ocorre na cidade de Erechim, onde o espaço dedicado às dependências da biblioteca pública não apresenta atratividade e área suficiente para que a população faça uso dele. Esse trabalho apresenta os resultados de um Trabalho Final de Graduação em arquitetura e urbanismo que teve como objetivo desenvolver uma proposta projetual para a biblioteca municipal de Erechim, de maneira a qualificá-la como equipamento que possa democratizar o acesso à informação e ao conhecimento, bem como ao lazer da população local.

A Case Study of the Use of Sandplay Therapy to Help Kids Feel Better about Starting Kindergarten
Authors: Wu Qiao
Published: October 2022

The purpose of this article is to investigate the efficacy of Sandplay Therapy (SPT) in reducing children’s kindergarten entrance anxiety in an effort to provide front-line preschool teachers with insights and strategies for addressing the emotional distress of children in their first days of nursery school. As a case study, the application of SPT to a 3-year-old boy who struggled with his transition into kindergarten was cited. The differences in his emotions and behaviors before and after six sessions of SPT were evaluated, revealing that the intervention through SPT significantly decreased his anxiety level while increasing his willingness to attend nursery school and that he finally developed a sound adaptation to the school, according to the comments of the observers. Findings showed that SPT could help kids feel less nervous about starting kindergarten and adjust better to new situations.
The relation between mandibular symphysis and the Angle class in orthodontic treatment
Authors: Nobre Ricardina , De Castro Saúl Matos , Ponces Maria João , Lopes Jorge Dias , Ferreira Afonso Pinhão
Published: October 2022

Objectives. Facial perception depends on the different components of the face. The chin is a striking anatomical structure in the individual’s identity and mandibular symphysis (MS) shape influences the adjacent soft tissue, determining facial harmony. In lateral cephalometry, the MS corresponds to the image of the mandibular body in its anterior curvature. It shape, inclination and thickness provide valuable information for orthodontic diagnosis and prognosis. Since facial features are associated with malocclusions, the present investigation aims to relate the height, thickness and inclination of the MS using Angle’s Class.

Methods. 495 lateral incidence cephalograms of an orthodontic population were analyzed using a previously developed and tested software. The sample was randomly selected and the height, thickness and inclination of the MS were measured. The values were statistically analyzed (p ≤ 0.05).

Results. The distribution according to Angle’s Class was 48.9% for Class I, 34.7% for Class II Division 1, 7.4% for Class II Division 2 and 8.9% for Class III. The MS height did not´t show significant differences between the three dental classes. The MS thickness was significantly increased in Class II Division 2 and Class I subjects (p = 0,037). The MS inclination was significantly less in Class III subjects when compared to Class I and Class II Division 1 (p ≤ 0.001).

Conclusions. The MS presented variations, which may be associated with a natural compensation against malocclusion, influencing the position of the teeth and their relationship with the other dento-craniofacial structures and with consequences on the facial harmony.

Authors: Podrihalo Olha , Xiaohong Guo , Mulyk Viacheslav , Podrigalo Leonid , Galashko Mycola , Sokol Konstantin , Jagiello Wladyslaw
Published: October 2022

Background and Study Aim. The increase in the popularity of sports dances recently has been confirmed. Dancing combines sports and aesthetic components. Dances are used for sports, recreational and rehabilitation purposes. The study aim is an analytical analysis of publications devoted to sports dances and the determination of priority scientific areas in this field. Material and Methods. The bibliometric database Web of Science Core Collection (WoS) is analyzed. For the primary analysis, 618 sources were selected which met the search criteria for 2018–2022. We used bibliometric methods for processing the information received in the context of sports dances for 173 sources. The VOSviewer 1.6.18 program was used: keyword analysis method and direct citation analysis with the construction of bibliometric maps, visualization of cluster density, weights – citations. Results. The constructed bibliometric maps made it possible to identify the leading thematic areas of research, current areas of research in this field. They can be divided into sports, recreational, medical and rehabilitation areas. The sports context is aimed at studying the performance of technical elements, the development of the physical qualities of athletes, the assessment of physical fitness, the dynamics of the morphofunctional state. Psychophysiological studies are aimed at analyzing balance and equilibrium. Publications of a recreational orientation study the health-improving use of dances, their impact on health. The medical and rehabilitation direction explores the features of sports injuries in dancing, injury prevention and the possibility of using dances in the complex rehabilitation. The use of the VOSviewer program, version 1.6.18, made it possible to conduct a comprehensive analysis of the problem, to determine the priority scientific directions in this area. Conclusions. The conducted bibliometric analysis of publications confirms the relevance of the problem of sports dances. A constant research interest in this problem has been determined. Research in this area has a pronounced sports and medical focus. Bibliometric analysis of publications allows identification the three following areas: sports, recreation and rehabilitation. Dancing is being explored as a sport, a form of physical activity, and a form of rehabilitation. A fairly high level of sports injuries has led to interest in the analysis of the prevalence and prevention of injuries. Its characteristic feature is the intersection of these directions. The study of athletes’ state confirmed the lack of works devoted to a comprehensive study of athletes, predicting success and skill growth. There are not enough works studying the physical state of sports dancers. There are practically no studies aimed at studying the psychophysiological state. These types of studies should be assessed as relevant.
Physical fitness of students based on a test used to assess the physical fitness of soldiers of the National Reserve Forces
Authors: Jalowska Pola , Prokopczyk Adam
Published: October 2022

Background and Study Aim.  The purpose of this study was to analyze the physical fitness of students based on a test used to assess the physical fitness of soldiers of the National Reserve Forces.

Material and methods. The study included 30 students majoring in Physical Education, specializing in Physical Education in the Uniformed Services. The average age of the subjects was 23.53 years, where the youngest subject was 21.92 years old and the oldest was 28.67 years old (SD = 1.513). The National Reserve Forces (NSR – abbreviation using in Polish language) physical fitness test was used to assess the level of physical fitness of professional soldiers. Students completed a proprietary research questionnaire to investigate the level and type of additional physical activity of the subjects, their future career plans related to the uniformed services, and their level of satisfaction with their performance on the fitness tests.

Results. It was shown that students who rated their level of preparation for uniformed service and satisfaction with their performance higher scored better on the NSR test. It was proven, equally, that students having a higher weekly volume of additional physical activity obtain higher scores in the fitness test. In addition, it has been demonstrated that better results in the fitness test are achieved by students who engage in physical activity at the level of active athletes.

Conclusions. The recommendation to introduce classes similar to sports training under battlefield conditions into schools and universities preparing future uniformed officers is justified. This would give a simultaneous improvement in physical fitness along with an increase in the level of self-efficacy for combat operations. Those wishing to enter the selection process for uniformed formations should practice regular physical activity, preferably at an intensity and volume close to the competitive level. This significantly affects the result achieved in the fitness test.

Published: October 2022

Background and Study Aim. Low-back pain (LBP) has increasingly been the leading cause affecting work performance, daily activities, and rising the cost of healthcare services. Currently, sitting time increases and walking activity lessens among people. The purpose of this study - identify the effect of Core Stabilization Exercise (CSE) with walking on pain perception and LBP disability among people who suffered from non-specific low-back pain (NSLBP).
Material and Methods. In this study, a total of 36 active people (18-42 years old) with BMI≥24.9 kg.m-2 voluntarily participated and were divided randomly into three groups. Intervention groups included CSE group (CSEG; n=12), CSE with walking (CSEWG; n=12), and control group (CG; n=12). The intervention groups carried out the exercise programs (CSE with and without 30 minutes of walking), three times a week for six weeks. In this study, the pain perception was assessed via the Numerical Pain Rating Scale (NPRS) and LBP disability was measured by using a modified Oswestry Disability (ODI) questionnaire.
Results. A one-way analysis of variance (ANOVA) displayed significant effectiveness of CSEG and CSEWG on pain perception as the interaction between time and group [f (2, 33) = 4.95, p=0.032]. The pain perception significantly decreased in CSEG (p=0.021) and CSEWG (p=0.003) after six weeks of the intervention programs compare to CG. The results also showed a significant effect on LBP disability for the interaction between time and group after six weeks of both intervention programs (f (2, 33) =6.52, p=0.015). Disability function (ODI score) significantly improved in CSEG (p=0.031) and CSEWG (p=0.007). Even though the results revealed no significant difference between CSEG and CSEWG, and both groups proved to reduce pain perception and LBP disability, the disability index improvement was greatest in CSEWG.
Conclusions. In conclusion, CSE with 30 minutes of walking, as an intervention program, has shown greater improvement with a larger effect size in pain perception and LBP disability among people who suffered from NSLBP.

Published: October 2022

Background and Study Aim. Various experimental programs for the development of motor skills are present in sports activities. Explosive strength can be defined as the ability to produce maximum force as soon as possible, and it represents an essential factor in activities where it is necessary to increase the acceleration of the body mass, the mass of specific body parts, or of an external object. The aim of study – to determine the effects of an experimental program on the explosive strength of lower limbs in male adolescents.

Material and Methods. One hundred and one male adolescent (aged 19 years ± 6 months; body height 181.43 ± 7.42 cm; body mass 80.08 ± 10.07 kg) were recruited and randomly divided into two groups: experimental group (E; N=48) and control group (K; N=48). The E group performed the experimental program which lasted fifteen weeks and consisted of three 60-min training sessions per week. All participants were tested on Squat Jump (SJ), Countermovement Jump (CMJ), Countermovement Jump with arms (CMJa) and Continuous Jump with Straight Legs (CJSL). The four tests were performed using a Kistler force platform to measure Quatro Jump Bosco Protocol Version 1.0.9.2 and gave us data about the jump height, number of jumps for 15s, average power jump and peak power jump. The multivariate analysis covariance (MANCOVA) and follow up analysis covariance (ANCOVA) were used to analyze the data.

Results. The results of MANCOVA showed statistically significant differences (p ≤ 0.001) between the E and K groups in all systems of variable lower limb explosive strength in male adolescents. In addition, results of ANCOVA showed statistically significant differences (p ≤ 0.001) in SJ, CMJ, CMJa and CJSL in favor of the E group compared to the K one.

Conclusions. The results of this research show that a fifteen-week experimental program can lead to significant improvements in lower limb explosive strength in male adolescents.

Objective: We report a rare case of salivary duct carcinoma possibly arising from the malignant component of carcinoma ex pleomorphic adenoma.

Methods: A 56-year-old Japanese male complained of swelling in the left side of jaw for 2 years which was painless until 2 days ago. On extraoral examination, the face was bilaterally asymmetrical. An ultrasonography revealed hypoechoic mass of size 1.5x2.5x2.5 cm on left parotid gland. Computed tomography (CT) revealed a slight irregular mass on left parotid gland with no infiltration to adjacent tissues. Based on these findings, a clinical diagnosis of left parotid benign tumor was made.

Results: A surgical excision was performed under general anesthesia. On histopathological examination, the connective tissue was rich in fibrous components and was accompanied by hyaline. Epithelial cells with high atypia proliferating invasively as cords into connective tissue were observed. The intraductal component had Roman-bridge-like architecture with central portion undergoing comedonecrosis. Based on these findings, a final diagnosis of salivary duct carcinoma possibly arising from pleomorphic adenoma was made. p16 hypermethylation is a known phenomenon in oral malignancy. We also checked the methylation status of p16 gene and found high level of methylation in this tumor.

Conclusion: We reported a rare case of salivary duct carcinoma possibly arising from pleomorphic adenoma and also demonstrated high methylation level of p16 gene in the tumor.

Published: November 2022

Temporary henna tattoos have become increasingly popular, particularly among children and teenagers. The word “henna” is of Persian origin, and it is prepared from the plant Lawsonia inermis belonging to the family Lythraceae. Concerning allergic reactions, natural henna paste is rarely responsible for contact dermatitis, which is more frequent if paraphenylenediamine (PPD) is added to the paste. The authors present a case of female child with erythematous exanthems that appeared after the application of black henna tattoo. A diagnosis of contact dermatitis to black henna tattoo was hypothesised. Epicutaneous tests were performed at the Immunoalergology Department of the Coimbra University Hospital using standard European battery and natural henna paste. The tests revealed positive reaction to PPD.
Finding Sensitive Accounts on Twitter: An Automated Approach Based on Follower Anonymity
Authors: Peddinti Sai , Ross Keith , Cappos Justin
Published: November 2022

We explore the feasibility of automatically finding accounts that publish sensitive content on Twitter, by examining the percentage of anonymous and identifiable followers the accounts have. We first designed a machine learning classifier to automatically determine if a Twitter account is anonymous or identifiable. We then classified an account as potentially sensitive based on the percentages of anonymous and identifiable followers the account has. We applied our approach to approximately 100,000 accounts with 404 million active followers. The approach uncovered accounts that were sensitive for a diverse number of reasons.
State of the Geotags: Motivations and Recent Changes
Authors: Tasse Dan , Liu Zichen , Sciuto Alex , Hong Jason
Published: November 2022

The widespread adoption of smartphones has made it possible for large numbers of people to geotag their social media posts. Past work has studied the reasons people tag their location and the ways they do so on location-based social networks like Foursquare. But it is unclear how well these findings generalize to other social media not centered on location, such as Twitter or Flickr. Through an analysis of public data and two surveys, we investigate why people geotag their photos, tweets, and other non-location-based social media. We found that their reasons are similar to those in location-based social networks. We also found several surprises due to the different nature of these platforms and the changes since location-based social networks were introduced. For example, people usually consciously geotag, though a significant portion geotags unintentionally; coordinate geotagging is changing to placetagging; and job-posting bots constitute a growing portion of public geotags.
Detecting Social Bots on Facebook in an Information Veracity Context
Authors: Santia Giovanni C. , Mujib Munif Ishad , Williams Jake Ryland
Published: November 2022

Misleading information is nothing new, yet its impacts seem only to grow. We investigate this phenomenon in the context of social bots. Social bots are software agents that mimic humans. They are intended to interact with humans while supporting specific agendas. This work explores the effect of social bots on the spread of misinformation on Facebook during the Fall of 2016 and prototypes a tool for their detection. Using a dataset of about two million user comments discussing the posts of public pages for nine verified news outlets, we first annotate a large dataset for social bots. We then develop and evaluate commercially implementable bot detection software for public pages with an overall F1 score of 0.71. Applying this software, we found only a small percentage (0.06%) of the commenting user population to be social bots. However, their activity was extremely disproportionate, producing comments at a rate more than fifty times higher (3.5%). Finally, we observe that one might commonly encounter social bot comments at a rate of about one in ten on mainstream outlet and reliable content news posts. In light of these findings and to support page owners and their communities we release prototype code and software to help moderate social bots on Facebook.
RAFFMAN: Measuring and Analyzing Sentiment in Online Political Forum Discussions with an Application to the Trump Impeachment
Authors: Tachaiya Jakapun , Gharibshah Joobin , Esterling Kevin E. , Faloutsos Michalis
Published: November 2022

Given an online forum, how can we quantify changes in user
affect towards a person or an idea over time? We argue that
online political forums constitute an untapped opportunity
for understanding sentiment toward aspects under discussion.
However, the analysis of such forums has received little attention
from the research community. In this paper, we develop
RAFFMAN, a systematic approach to quantify the impact of
external events on the affect of forum users towards a concept,
such as a person or an entity. First, we develop an approach
to capture and quantify the observed activity: we identify related
keywords, filter threads, and establish correlations between
events and spikes in the activity. Second, we modify
and evaluate state-of-the-art NLP techniques to achieve high
accuracy (74%) in a three-class sentiment classification problem.
As a case study, we deploy our method to quantify the
effect of President Trump’s impeachment on several concepts
including: President Trump, Speaker Pelosi, and QAnon. Our
data consists of 32M posts from Reddit and 4chan over a span
of 6 months from September 2019 to February 2020. This initial
analysis hints at an increase in political polarization, especially
for people’s affect towards the President. Overall, our
work is a building block towards mining the affect of online
forum user towards a concept, which constitutes a untapped,
massive, and publicly-available source of information.
Improving Zero-Shot Cross-Lingual Hate Speech Detection with Pseudo-Label Fine-Tuning of Transformer Language Models
Authors: Zia Haris Bin , Castro Ignacio , Zubiaga Arkaitz , Tyson Gareth
Published: November 2022

Hate speech has proliferated on social media platforms in recent years. While this has been the focus of many studies, most works have exclusively focused on a single language, generally English. Low-resourced languages have been neglected due to the dearth of labeled resources. These languages, however, represent an important portion of the data due to the multilingual nature of social media. This work presents a novel zero-shot, cross-lingual transfer learning pipeline based on pseudo-label fine-tuning of Transformer Language Models for automatic hate speech detection. We employ our pipeline on benchmark datasets covering English (source) and 6 different non-English (target) languages written in 3 different scripts. Our pipeline achieves an average improvement of 7.6% (in terms of macro-F1) over previous zero-shot, cross-lingual models. This demonstrates the feasibility of high accuracy automatic hate speech detection for low-resource languages. We release our code and models at https://github.com/harisbinzia/ZeroshotCrosslingualHateSpeech.

Microblogging websites such as Twitter are increasingly being used by businesses/campaigners for timely dissemination of information to their followers. The diffusion of a tweet depends on several factors: the activity of the follower nodes, the responsiveness of follower nodes to tweets from the source node, the out-degree of the follower nodes, the content of recent related tweets seen by the follower node, etc. Using such factors, in this paper, we propose a framework to measure the effectiveness of an information campaign over Twitter. We consider a positive as well as a negative metric to measure the impact of a tweet: while retweets are used to measure the positive impact, the lack of a timely response from an active follower node is taken as a potential negative impact. We investigate the scheduling of tweets to increase the net positive impact while keeping the net negative impact below a desired level. We propose and study several scheduling algorithms by casting the problem in a Markov Decision Process (MDP) framework. In order to compare our algorithms, we estimate the model parameters from tweet data collected using the Twitter API from an arbitrarily selected node and its 6837 followers over several months. For this dataset, we find that if successive tweets in the campaign are novel, then substantial gains over user activity based scheduling can be obtained by scheduling tweets in time slots where the ratio of the expected positive and negative metrics is high. We call this the MaxRatio policy and we show that it is optimal under certain conditions. In cases where we are not certain about the response of users to successive related tweets, we identify another algorithm (which we call MaxReach) as a robust alternative.
Reconstruction of Threaded Conversations in Online Discussion Forums
Authors: Aumayr Erik , Chan Jeffrey , Hayes Conor
Published: November 2022

Online discussion boards, or Internet forums, are a signiﬁcant part of the Internet. People use Internet forums to post questions, provide advice and participate in discussions. These online conversations are represented as threads, and the conversation trees within these threads are important in understanding the behaviour of online users. Unfortunately, the reply structures of these threads are generally not publicly accessible or not maintained. Hence, in this paper, we introduce an efﬁcient and simple approach to reconstruct the reply structure in threaded conversations. We contrast its accuracy against three baseline algorithms, and show that our algorithm can accurately recreate the in and out degree distributions of forum reply graphs built from the reconstructed reply structures.
Is the Sample Good Enough? Comparing Data from Twitter's Streaming API with Twitter's Firehose
Authors: Morstatter Fred , Pfeffer Jürgen , Liu Huan , Carley Kathleen
Published: November 2022

Twitter is a social media giant famous for the exchange of short, 140-character messages called "tweets". In the scientific community, the microblogging site is known for openness in sharing its data. It provides a glance into its millions of users and billions of tweets through a "Streaming API" which provides a sample of all tweets matching some parameters preset by the API user. The API service has been used by many researchers, companies, and governmental institutions that want to extract knowledge in accordance with a diverse array of questions pertaining to social media. The essential drawback of the Twitter API is the lack of documentation concerning what and how much data users get. This leads researchers to question whether the sampled data is a valid representation of the overall activity on Twitter. In this work we embark on answering this question by comparing data collected using Twitter's sampled API service with data collected using the full, albeit costly, Firehose stream that includes every single published tweet. We compare both datasets using common statistical metrics as well as metrics that allow us to compare topics, networks, and locations of tweets. The results of our work will help researchers and practitioners understand the implications of using the Streaming API.
Modeling Response Time in Digital Human Communication
Authors: Navaroli Nicholas , Smyth Padhraic
Published: November 2022

Our daily lives increasingly involve interactions with other individuals via different communication channels, such as email, text messaging, and social media. In this paper we focus on the problem of modeling and predicting how long it takes an individual to respond to an incoming communication event, such as receiving an email or a text. In particular, we explore the effect on response times of an individual's temporal pattern of activity, such as circadian and weekly patterns which are typically present in individual data. A probabilistic time-warping approach is used, considering linear time to be a transformation of "effective time,'' where the transformation is a function of an individual's activity rate. We apply this transformation of time to two different types of temporal event models, the first for modeling response times directly, and the second for modeling event times via a Hawkes process. We apply our approach to two different sets of real-world email histories.The experimental results clearly indicate that the transformation-based approach produces systematically better models and predictions compared to simpler methods that ignore circadian and weekly patterns.

A growing number of people are changing the way they consume news, replacing the traditional physical newspapers and magazines by their virtual online versions or/and weblogs. The interactivity and immediacy present in online news are changing the way news are being produced and exposed by media corporations. News websites have to create effective strategies to catch people’s attention and attract their clicks. In this paper we investigate possible strategies used by online news corporations in the design of their news headlines. We analyze the content of 69,907 headlines produced by four major global media corporations during a minimum of eight consecutive months in 2014. In order to discover strategies that could be used to attract clicks, we extracted features from the text of the news headlines related to the sentiment polarity of the headline. We discovered that the sentiment of the headline is strongly related to the popularity of the news and also with the dynamics of the posted comments on that particular news.
Understanding Musical Diversity via Online Social Media
Authors: Park Minsu , Weber Ingmar , Naaman Mor , Vieweg Sarah
Published: November 2022

Musicologists and sociologists have long been interested in patterns of music consumption and their relation to socioeconomic status. In particular, the Omnivore Thesis examines the relationship between these variables and the diversity of music a person consumes. Using data from social media users of Last.fm and Twitter, we design and evaluate a measure that reasonably captures diversity of musical tastes. We use that measure to explore associations between musical diversity and variables that capture socioeconomic status, demographics, and personal traits such as openness and degree of interest in music (into-ness). Our musical diversity measure can provide a useful means for studies of musical preferences and consumption. Also, our study of the Omnivore Thesis provides insights that extend previous survey and interview-based studies.
Culture, Networks, Twitter and foursquare: Testing a Model of Cultural Conversion with Social Media Data
Authors: Joseph Kenneth , Carley Kathleen
Published: November 2022

Social network research often takes the view that networks chiefly influence the spread of culture, with few reciprocal effects. While some network scholars have implied a coevolutionary relationship between the two, cultural sociologists have provided increasingly convincing evidence that it is in fact cultural preferences which mediate network structure, rather than the other way around. In the present work, we attempt to validate one such model of the conversion of cultural capital to network position. We use Twitter data to extract the ego networks of individuals and foursquare check-ins to understand their cultural preferences. Our results are indicative of the importance of considering sociological models in which culture influences network structure.
Explainable Problem in clingo-dl Programs
Authors: Nguyen Van , Son Tran Cao , Yeoh William
Published: November 2022

Research in explainable planning is becoming increasingly important as human-AI collaborations become more pervasive. An explanation is needed when the planning system’s solution does not match the human’s expectation. In this paper, we introduce the explainability problem in clingo-dl programs (XASP-D) because clingo-dl can effectively work with numerical scheduling, a problem similar to the explainable planning.
