Implications of Activity Classification Aggregation in Urban Freight Trip Generation Linear Models
Authors: Sanchez-Diaz Ivan D. , Gonzalez-Feliu Jesus
Published: June 2019

This chapter studies the implication of aggregating establishments by categories with different levels of detail for modeling FTG. To this effect, the chapter conducts an assessment of freight trip generation (FTG) patterns homogeneity inside activity-based grouping. The method implemented is econometric in nature, which allows the assessment of the statistical significance of variables representing commercial activity sectors and sub-sectors. The results show that for some sectors the traditional high-level aggregation includes sub-sectors with homogenous FTG patterns and thus produces appropriate models; in some other cases (e.g., retail, manufacturing), the sub-sectors have different FTG patterns and thus more detailed data is needed to calibrate accurate models. This research can be used to enhance the efficiency of data collection, as it identifies some sub-sectors that need larger efforts for data collection, and some other categories where FTG homogeneity allows for less detailed data collection without hampering the quality of the models.

Authors: Vargas-Florez Jorge , Alva-Cabrera Rafael A.
Published: June 2019

Natural disasters produce enormous human and material losses. This is amplified if there is poor relief aid humanitarian distribution. Logistics seeks to obtain efficiencies related to response reducing transportation costs; according to humanitarian institutions, they constitute the second largest general expense after labor. Humanitarian distribution challenges are reduce costs, maintaining distribution service, and designing reliable delivery routes in a context where infrastructures may be non-existent, unavailable, or inoperative. This chapter addresses the problem of optimizing the distribution of humanitarian aid by comparing different clustering strategies for the medicines warehouse in charge of the national hospital services entity in Metropolitan Lima and Callao. The chapter is organized as follows. First, a review of the literature on problem of vehicle routing for resilient networks are presented. Then the proposed model will be shown considering those limitations to humanitarian delivery in a post-disaster context; finally, feasible solutions will be compared.

Authors: Junior Irineu de Brito , Guerrero Ernesto , Machuca Juan , Chong Mario
Published: June 2019

This chapter develops a decision support tool with a focus on the humanitarian logistic chain in a crisis environment considering process drivers' constraints such as costs, capacity, and throughput time. For instance, elements to reduce the suffering of the affected families, by using an adequate supply support for the first 72 critical hours. The authors will focus on minimizing the risks of shortages in the first response supplies in a high flood probability zone in Peru. This research presents different scenarios and it analyzes the representative variables (demand, civil defense warehouses, points of distribution, distance and logistics resources), the humanitarian chain value, and the effective distribution of the aid in the affected areas with efficient operations that balance between the economic and operative resources in this recurrent logistical problem. The results present three crisis situations with a distribution plan and a base of a public policy to prevent a crisis.
Comparison of Multi-Criteria Decision-Making Techniques for the Location of Multi-Modal Terminals in an Integrated Public Urban Transport System
Authors: Camargo-Pérez Johanna , Montoya-Torres Jairo R.
Published: June 2019

Multiple actors from both private and public sectors are currently involved in the design and operation of urban passenger transport systems seeking at optimizing their own objectives. Multi-criteria decision-making (MCDM) techniques actually aid this process. In this chapter, the authors consider the problem of locating multimodal terminals of an integrated public passenger transport system (IPPTS). A case study for the city of Bogota, Colombia is evaluated. Majority of works in MCDM does not explicitly justify the choice of the applied technique. This chapter applies three different techniques, AHP (analytic hierarchy technique), ELECTRE II (elimination and choice expressing the reality), and CRITIC (criteria importance through intercriteria correlation), to solve problem. A feature of this study is that traditional economic and logistic criteria are evaluated together with environmental and social criteria not previously evaluated in the literature. Numerical results show that each multi-criteria approach may prefer a different alternative, depending on the intrinsic behavior of each technique.

Published: June 2019

The ubiquity of the internet led to a diverse number of devices referred to as the “things” to have online access. The internet of things (IoT) framework's infrastructure is formed by sensors, actuators, computer servers, and the communication network. Within this framework, the chapter focuses on IoT interoperability challenges through virtualization agility. The use of SDN/NFVs aims to face the 5G interoperability challenge by allowing the automatic deployment and programming of network services. Consequently, virtual gateways need to be used so that interoperability is ensured between various objects and technologies. As a result, experiments will be performed on various IoT platforms which consist of physical and virtual parts. In specific, the process will be on top of a testbed so that MQTT, CoAP, and UDP protocols will be instantiated and set up in order to provide an interoperable layer using a virtual gateway.

Authors: El Fawal Ahmad Hani , Mansour Ali , Najem Mohamad
Published: June 2019

This chapter envisions the challenges that will face the mobile operators such as sending vehicle-to-vehicle (V2V) payloads in form of synchronized storms, the fast saturation of the limited bandwidth of long-term evolution for machines (LTE-M) and narrow band-internet of things (NB-IoT) with the rise number of machine-to-machine (M2M) devices and V2V devices, V2V congestion overload problem in IoT environments specifically during disaster events. It extends a new solution proposed by the authors named Adaptive eNodeB (A-eNB) for both LTE-M and NB-IoT networks to deal with V2V excessive traffic. The A-eNB can solve gradually V2V overload problem, while keeping the human-to-human (H2H) traffic quality of service (QoS) not to be affected badly. It corroborates a new framework model proposed by the authors called coexistence analyzer and network architecture for long-term evolution (CANAL) to study the impact on V2V, M2M, and H2H and mutual influences, based on continuous-time Markov chain (CTMC) to simulate, analyze, and measure radio access strategies.

Published: June 2019

This chapter highlights the role of universal design for learning in inclusive classrooms. How teachers design instruction to meet the diverse needs of all learners in inclusion classrooms is where the importance of universal design for learning lies. UDL is the “what,” “how,” and “why” of learning; its principles provide for multiple means of engaging students, multiple representations of instructional methods and materials, multiple types of student responses, and multiple means of evaluating performance. Presented from the context of multiple literacies including media literacy, this chapter explains how UDL can be applied in the classroom in concert with response to intervention, mastery learning, and repeated measures strategies. This chapter strongly argues the utility of using universal design for learning and its benefits for teaching in inclusion classrooms.
Media Literacy in a Digital Age
Authors: Saçak Begüm
Published: June 2019

New possibilities of representation through the use of multiple modes has challenged language's power as a dominant means to express meanings. Multimodal communication is now becoming the norm in the modern era of communication and Internet. Diverse forms of media exist and are combined in different ways to create new meanings though what constitutes media (media language or visual grammar), and the motivations behind design often remain transparent to users. The increase and diversity in different forms of representation other than written or spoken language also bring along changes in the field of literacy. In this chapter, the main focus is on Multimodal Social Semiotics —the theory of communication formed by Kress and his colleagues. The new language of multimodality and design builds on what it means to be media literate and has significant implications for media literacy education. This chapter's focus is on the basics of reading multimodal texts and the connection between new literacy and media literacy studies based on Multimodal Social Semiotics Theory.
Media Literacy Education in the Era of Post-Truth
Authors: Friesem Elizaveta , Friesem Yonty
Published: June 2019

In this chapter, the authors use Kuhn's theory of scientific revolutions to examine the development of media literacy as a field of study and practice. More specifically, they focus on the current stage of media literacy, which they believe to be model drift that reveals the emerging crisis of the current paradigm based on epistemological assumptions of modernity. The authors look at this stage against the current social background of the era of post-truth and through the prism of ongoing debates between different media (literacy) scholars and educational practitioners. The era of post-truth can be seen as a logical manifestation of postmodernity, when the idea that truth and facts are relative is becoming part of the public discourse. In this period, different scholars and practitioners offer different ideas on what media literacy is and what its import may be. These debates are not new; yet, today they might have more serious consequences, signaling a need to reevaluate the existing paradigm that has formed the foundation of media literacy education since the field's emergence.
Perception Is (as) Reality
Authors: Knight Catherine , Calemmo Margaux
Published: June 2019

It is the goal of this chapter is to explore the challenges inherent to a “post-fact” society through the lens of the school public information specialist and the library media specialist. The role of the school public information officer (PIO) has changed with the proliferation of opinion as “fact” on the internet and social media. Educating the public on all school-related matters, PIOs must be media-literate, effective content consumers and content generators, with the skills to gauge and predict the opinions of their voting public. Similarly, library media specialists tasked with educating students as consumers of information in the fast-paced, “on demand” digital age requires an understanding of their evolving role as content generators. Effective media literacy instruction encompasses more than simply using technology and electronic media in the educational setting. Rather, it begins with the understanding that students are ill equipped to critically evaluate the electronic mediums they so closely identify with.

Importance of Data Management in Digital Media Literacy
Authors: Kömeçoğlu Yavuz , Muftuoglu Zumrut , Umay Can , Tasdelen Aysin , Ozdemir Sebnem
Published: June 2019

A digital literate person is identified as competent person in the three dimensions of digital technologies, defined as technical, cognitive, and socio-emotional. In particular, under the technical dimension, the person is able to use the tools of the digital world in a competent way. Considering this definition given in technical dimension, it is seen that the individual being a good digital literate is also related to the tools of the digital world. However, no matter how good a digital literate can be, she/he is suffocated in the information if there is no tool to help in accessing information in a certain area, because of the size of digital world. The purpose of this study is to strengthen the technical dimension of digital literacy by developing a tool for reaching the correct visuals by using deep learning techniques. In order to fulfill that purpose, transferring cultural heritage to the next generation by avoiding disturbing visuals, was focused.

Authors: Abdullah Suhail , You Kok Yeow , Chong Cheong Yew , Ali Mohamed Sultan Mohamed
Published: June 2019

Mono-mode microwave reactors are usually used to heat substances, especially food. This is because heating using a microwave reactor can sustain the flavor, color, and nutrition of the food. Furthermore, this heating technique is cost-effective and time-saving compared to a conventional heating method. The mono-mode reactor is able to determine the absorption of microwave power accurately on the heated substance versus a multimode reactor. In this chapter, a simple and precise mono-mode microwave reactor is designed and developed especially for research laboratories. The advantage of this reactor is to provide a more accurate calibration process, in order to improve the optimum energy use in the heating process, as well as the temperature of the specimen. The reactor can generate output power from 30 watts to 1500 watts, operating at 2.45±0.03 GHz and capable of accommodating a specimen volume of 780 cm3. Pure water is used as a heated specimen to demonstrate the performance and efficiency of this reactor.

Authors: Royce Christine Anne , German Susan
Published: June 2019

With the continued growth of digital tools and practices, the manner in which instruction is planned and delivered within a middle-level classroom will need to evolve. Science educators have often been in the forefront of technology inclusion. With the current expectations of three-dimensional learning promoted within the Next Generation Science Standards, teachers have additional opportunities for students to utilize digital tools and practices during their instructional process. Through the utilization of carefully selected digital tools and practices, science teachers can engage learners and better assist them in constructing meaning through three-dimensional learning. The authors focus on the intersection of three areas: how middle school students make sense of content and develop understanding, the utilization of strategies for designing and creating a middle school classroom around digital practices, and the challenges and opportunities that this instructional shift encounters.
Lessons Learned
Authors: Bussert-Webb Kathy , Lewis Karin A.
Published: June 2019

The authors focus on digital literacy and community service learning (CSL) strategies from research of Latinx undergraduate teacher candidates (TCs) engaged with technology in CSL courses. The qualitative studies have taken place in a tutorial agency and university classrooms in the Rio Grande Valley, Texas, one of the most economically-strapped U.S. regions. The 60 participants were Bussert-Webb's TCs in Summer 2016 and Summer 2017 (n=28) and Lewis's TCs in Fall 2018 and Spring 2019 courses (n=32). Data sources include participant observations, surveys, focus groups, lessons, and reflections. Using social justice and New Literacies frameworks and thematic data analysis, the authors discuss four concepts that have influenced their practices: 1) risk-taking is more important than our digital expertise, 2) digital literacy connects to social justice contexts, 3) TCs engage in authentic technology experiences, and 4) technology-infused CSL is provided. Implications relate to closing a three-tier digital divide among Latinx teachers and youth.
Multimedia Learning
Authors: Wuerzburger Jared , Henriquez Oscar G.
Published: June 2019

Instructors, professors, and lecturers are always seeking to provide students with real-world experiences that provide hands-on instruction, particularly in technical, engineering, and professional education environments. Many barriers to providing realistic project-oriented classroom experiences include safety, overall cost, procurement of necessary laboratory components, and available physical space. The study conducted analyzed the two randomly sampled student groupings of digital experiences and real-world experiences at a midwestern university, with groupings named traditional hands-on lab and MultiSim, respectively. Grouping 1 utilized digital labs simulations utilizing MultiSim while Grouping 2 used the traditional form of physical labs. The analysis did not indicate a statistically significant difference in student performance between groups using MultiSim (M=26.38, SD=14.527) and students using traditional hands-on methods (M=21.39, SD=16.284) t(45)=-1.11, p=.274. Implications, and recommendations are featured to provide context.
Learning From Failure
Authors: Bishop Natalie Edwards , Allford Hannah
Published: June 2019

Integrating the research and writing process is a stuck place for many students. Leveraging the collaborative conversation through feedback loops confronts stuck places that are critical to students mastering concepts in composition and information literacy. Instructors and librarians, in turn, are more clearly able to identify “stuck places” where students struggle with concepts and build learning experiences around those places. Implementing the collaborative conversation through Google Drive apps allows students, instructors, and librarians a platform to collaborate through shared editing and commenting. As a result, the process of providing feedback is less linear, shifting to an integrative, conversation-based experience. Google Drive affords stakeholders sufficient wait time to contextualize research, respond to feedback, and revise writing. Instructors and librarians are able to model the reflexive, iterative processes of inquiry, research, and writing alongside their students through implementation of the Research, Writing, and Feedback Integration Model.

Narratives of Erasure
Authors: Issar Lucky
Published: June 2019

This chapter examines R.K. Narayan's novel The English Teacher as a narrative of caste erasure. As he goes on to construct his “authentic,” “brahminical” India, he effectively erases caste-others by creating an exclusive, selective imaginary of Indian nation as upper-caste. This construction requires caste erasure and suppression of “queerness” that constantly poses a threat to caste-based ideological formulations of Indian society as brahminical, Hindu, and hetero-normative. Through the close reading of the text, the author shows that caste not only damages Dalits, but it makes a deleterious impact on the upper castes and by extension on the whole Indian society.
The Metric Structure of Nucleic Acids and the Higher Dimension of Their Constituents
Authors: Zhizhin Gennadiy Vladimirovich
Published: June 2019

The purpose of the study is to build a metric model of the structure of a nucleic acid molecule, taking into account the higher dimension of its components, the actual lengths of chemical bonds, and the angles between them. Calculations by the constructed model showed the closeness of the known experimental characteristic parameters of the nucleic acid (helix diameter, period length) and the calculated values of these parameters. The internal degree of freedom of the nucleic acid molecule is revealed: the angle of rotation of the phosphoric acid residue relative to the chemical bond connecting it to the five-carbon sugar molecule. It is established that the value of this angle determines the shape of the nucleic acid molecule. It is claimed that the process of transmission of hereditary information and protein synthesis occurs in a space of high dimensionality in ribosomes.
Amplitude-Frequency Characteristics of the Oscillations of Methane Gas Bubbles in Oil
Authors: Naghiyev Faig Bakhman Ogli
Published: June 2019

The author presents an analytical solution to the problem of acoustic-wave-induced oscillations of methane gas bubbles in an oil reservoir at bottom-hole conditions. The amplitude-frequency characteristics are computed for realistic reservoir temperature, pressure, and dissolved gas parameters that make the oil compressibility, density, and viscosity quite different from those of the degassed oil at surface conditions. The author compares the damping decrement of these ultrasonic oscillations to those at normal atmospheric-pressure surface conditions. The solution allowed the author to estimate the ultrasonic vibration frequency range that is optimal and most effective for improving the flow characteristics in a producing reservoir in the near-well zone at a realistic bottom-hole regime.

Published: June 2019

Pictures speak louder than words. In this fast-moving world where people hardly have time to read anything, photo-sharing sites become more and more popular. Instagram is being used by millions of people and has created a “sharing ecosystem” that also encourages curation, expression, and produces feedback. Museums are moving quickly to integrate Instagram into their marketing strategies, provide information, engage with audience and connect to other museums Instagram accounts. Taking into consideration that people may not see museum accounts in the same way that the other museum accounts do, the article first describes accounts' performance of the top, most visited museums worldwide and next investigates their interconnection. The analysis uses techniques from social network analysis, including visualization algorithms and calculations of well-established metrics. The research reveals the most important modes of the network by calculating the appropriate centrality metrics and shows that the network formed by the museum Instagram accounts is a scale–free small world network.
On the End-to-End Development of a Cultural Tourism Recommender
Authors: Pavlidis George P.
Published: June 2019

Recommenders are systems that employ some knowledge on items and user preferences, along with sophisticated algorithms to provide personalised content and services. They have been around to tackle the information overload and personalisation demand in today's always-connected world. This technology appeared in the cultural heritage domain relatively recently, but the bibliography is already rich, as cultural tourism plays an important role for regional economies. From the technical perspective, different approaches, like collaborative filtering, content-based, knowledge-based and hybrid approaches, have been adopted. From the intuition perspective, the approaches are influenced by current conceptualisation and specific application domains and demands. The museum has been one of the main target applications, either as a part of visit support or in the context of cultural tourism initiatives. This article presents a review of the domain and draws a generic blueprint for the end-to-end development of a recommender for cultural tourism that outperforms a baseline popularity-based approach.

IT Project Communication
Authors: Bigbee Jo Ann Starkweather , Stevenson Deborah H.
Published: June 2019

The critical nature of information flow as a precursor to project success has been affirmed by both scholars and project management professionals. The data analyzed in this study represent the perceptions of 91 IT project professionals regarding the importance of 18 different aspects of project communication to project success. The relationship of these data vis-a-vis project manager demographics and project/organizational characteristics is explored. Despite a relatively high level of agreement across the respondents regarding which communications are perceived critical to project success, there are clear project and stakeholder circumstances that warrant consideration. The data reveal both statistical and practical dimensions of communication that attribute importance to project success differently for internal as compared to external communication. Furthermore, the emergence of average project duration as a consistently strong correlate of perceived importance of communication to project success is an area of research deserving greater attention.
Enhancing Rating Prediction by Discovering and Incorporating Hidden User Associations and Behaviors
Authors: Pradhan Ligaj
Published: June 2019

Collaborative filtering (CF)-based rating prediction would greatly benefit by incorporating additional user associations and behavioral similarity. This article focuses on infusing such additional side information in three common techniques used for building CF-based systems. First, multi-view clustering is used over neighborhood-based rating predictions. Secondly, additional user behavior knowledge discovered by mining user reviews are infused into non-negative matrix factorization (NMF) techniques. Finally, the article explores how to infuse such additional behavioral knowledge into a Deep Neural Network (DNN) based DF architecture. The article also explores using term frequency-inverse document frequency (TF-IDF) vectors as the input to DNN. Since TF-IDF does not directly capture the conceptual contents of the text or the behavioral aspects of the writer, the article also proposes a novel scheme called topic proportions-inverse entity frequency (TP-IEF) that uses topics discovered from reviews instead of words to better capture semantic associations between users and items.

Authors: Muliawaty Lia , Alamsyah Kamal , Salamah Ummu , Maylawati Dian Sa'adillah
Published: June 2019

The implementation of bureaucratic reform in Indonesia is not optimal and faces various obstacles. At present, public services demand excellent service and meet public satisfaction. The obstacles are rigid bureaucracy, incompetent bureaucrats or apparatuses, not professional, and there are technological gaps. Rapid technological development, such as digital technology and big data, has not been responded to positively by most bureaucrats. Big Data has a great potential for improving bureaucratic and public services. With a qualitative method and a waterfall software development life cycle, this article provides the design of a bureaucracy sentiment analysis application which implements Big Data technology for analyzing the opinions about bureaucratic service in Indonesia. This is for the purpose that the bureaucratic services can be improved based on societal opinion. The results of the experiment using RapidMiner showed that sentiment analysis as a Big Data technique for bureaucratic service based on societal opinion can be used to evaluate performance better.

This paper discusses an environmentally-friendly destination for the residual ashes resulting from the firing of biomass (wood wastes) at the Engie Brasil Cogeneration Power Plant located in Lages, Santa Catarina, Brazil. The study proposes reusing the residue as a substitution for crushed stones in the production of concrete. Environmental, physical, and chemical analyses were performed for characterization of the ashes. Specimens prepared with ash and subjected to testing presented a compressive strength of around 18.63 Mpa (2700 psi), which is in compliance with the ACI-213R and ASTM C330-5 specifications. With pretreatment and proper mixing ratios, biomass ashes may be employed as an aggregate in the manufacture of lightweight structural concrete.

Several zeolite membrane types, including Mordenite (MOR), Linde Type A (LTA), and Faujasite (FAU), have been developed. Among these membranes, FAU zeolite membranes have a variety of applications, especially in the separation of mixtures that contain large molecules. The goal of this study is to use zeolite membranes (Y/alumina) to separate suspensions of oil-in-water emulsion. Two ceramic supports were prepared from the alumina at different sintering temperatures (700°C and 1200°C) to obtain gamma-alumina and alpha-alumina, respectively. The materials prepared, zeolite Y membranes/alpha-alumina and Y/gamma-alumina, were characterized using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The powder pressing method was used to compact the alpha-alumina and gamma-alumina ceramic support and the dip-coating method was used to prepare the zeolite Y membranes. The XRD pattern showed that the zeolite Y membrane/alumina obtained by the secondary growth dip-coating method, independent of the ceramic support used, showed no trace of the phases characterized as impurities. It was possible to observe a significant reduction in the concentration of oil in the permeate for the zeolite Y membranes, thus showing their potential for use in this application.

Swede midge (Contarinia nasturtii (Kieffer); Diptera: Cecidomyiidae) is a serious invasive pest of Brassica Linnaeus (Brassicaceae) oilseed and vegetable crops in Canada and the United States of America. Pheromone mating disruption is a promising new tactic for managing this difficult pest, but research is needed to determine how pheromone delivery can be optimised. With an understanding of swede midge diel mating patterns, pest managers could limit pheromone release to periods when midges are sexually active. We conducted a series of 24-hour trials to test whether swede midge exhibit diel periodicity of emergence, female calling, and male capture in pheromone traps. We found that females began releasing pheromones almost immediately following emergence within the first five hours after dawn. In the field, we found that males were most active from dawn until late morning, indicating that midges mate primarily during the first five hours of photophase. Low levels of reproductive activity during midday and nighttime hours present opportunities to turn off dispensers and reduce the cost of pheromone inputs in a swede midge mating disruption system.

Evaluating operationalisation of integrated monitoring and evaluation system in Kisumu County: Implications for policy makers
Authors: Warinda Enock
Published: June 2019

Background: Evaluation findings are increasingly becoming valuable for policy makers in Kenya. The Directorate of Monitoring and Evaluation is responsible for providing reliable data findings for decision-makers. They are in turn expected to access the data and information through the National Integrated Monitoring and Evaluation System (NIMES). Unfortunately, the directorate hardly receives timely data as required, thus is unable to make timely decision within the ministry of agriculture, livestock and irrigation in Kisumu County.Objectives: The aim of this study was to assess the extent of operationalisation of NIMES through utilisation of the electronic project management information system (e-ProMIS) within the three agricultural departments.Methods: Through single-point face-to-face interviews using semi-structured questionnaires, mixed methods approach and Likert scale were applied to assess the level of operationalisation of, staff competences in, and satisfaction with NIMES. Both random and purposive sampling was used. Using mixed methods approach, primary and secondary data were collected from 10 key indicators and fitted in a binary logistic regression model to assess the level of operationalisation of NIMES.Results: This article shows that operationalisation of NIMES is unsatisfactory, and data collected are incorrectly formatted. None of the departmental personnel charged with uploading relevant data in e-ProMIS neither accessed nor utilised the platform. There were no champions supporting NIMES, thus no reports generated from the system.Conclusions: Factors hindering operationalisation of NIMES were: dysfunctional monitoring and evaluation (M&E) systems, limited human capacity on M&E, lack of NIMES champions, limited availability of data, unclear information flow to decision makers and inadequate integration of NIMES in planning and budgeting.
A life design-related career development intervention for working adults in the manufacturing, engineering and related sectors
Authors: Taylor Nicola , Beukes Chris
Published: June 2019

This study examined the potential usefulness of a life design-related career development intervention to enhance the career adaptability of working adults in a business sector most likely to be disrupted by technology and robotics. Participants were employed at a manufacturing workshop in a South African correctional centre. A mixed-methods intervention study design was implemented. The participants completed a number of career-based assessments during the intervention. The results indicated that the participants were well prepared to face the career challenges presented by Industry 4.0 and that the intervention shows promise in improving career adaptability in working adults. More longitudinal research with diverse participants is needed.
