The purpose of hypothesis testing is to provide the decision maker with an efficient mechanism for reducing uncertainty using an inferential procedure to test the credibility of a potential solution to a strategic challenge. This is done by choosing an initial hypothesis about how to solve a problem and limiting data collection and analysis to those data that either defend or reject this hypothesis. This can be far more efficient than traditional methods of collecting data without purpose and deducing solutions by analyzing relevant data and eliminating irrelevant data along the way. This chapter discusses the underlying theory, core idea, depiction, process, insight or value created, and risks and limitations of hypothesis testing. The chapter also continues the illustration of the DISH Network and applies the steps of hypothesis testing to this case.

The chapter presents a rationale for using visual ethnography as part of the methodology in qualitative research and illustrates what visual ethnography methodology is capable of accomplishing when imagery is included in the investigative process. Visual ethnography offers a venue for collecting and analyzing data that would otherwise be inaccessible and positions imagery as an important, rather than a minimal or occasional, choice for use in qualitative research. Topics include contemporary definitions of visual ethnography and its value in qualitative research, historical applications of visual ethnographic theory that influence the way researchers view visual ethnography today, and contemporary uses of visual ethnography in data collection and analysis. Finally, the conclusion explores the future of visual ethnography.

Wireless sensor networks (WSN) are used by engineers to record the behavior of structures. The sensors provide data to be used by engineers to make informed choices and prioritize decisions concerning maintenance procedures, required repairs, and potential infrastructure replacements. However, reliable data collection in the field remains a challenge. The information obtained by the sensors in the field frequently needs further processing, either at the decision-making headquarters or in the office. Although WSN allows data collection and analysis, there is often a gap between WSN data analysis results and the way decisions are made in industry. The industry depends on inspectors’ decisions, so it is of vital necessity to improve the inspectors’ access in the field to data collected from sensors. This paper presents the results of an experiment that shows the way Augmented Reality (AR) may improve the availability of WSN data to inspectors. AR is a tool which overlays the known attributes of an object with the corresponding position on the headset screen. In this way, it allows the integration of reality with a virtual representation provided by a computer in real time. These additional synthetic overlays supply data that may be unavailable otherwise, but it may also display additional contextual information. The experiment reported in this paper involves the application of a smart Strain Gauge Platform, which automatically measures strain for different applications, using a wireless sensor. In this experiment, an AR headset was used to improve actionable data visualization. The results of the reported experiment indicate that since the AR headset makes it possible to visualize information collected from the sensors in a graphic form in real time, it enables automatic, effective, reliable, and instant communication from a smart low-cost sensor strain gauge to a database. Moreover, it allows inspectors to observe augmented data and compare it across time and space, which then leads to appropriate prioritization of infrastructure management decisions based on accurate observations.

Digital methods allow social researchers and IT professionals to work together to produce instruments to comprehend current social phenomena. To develop these tools, they felt the need to “follow the medium” by reorganizing their data collection and analysis strategies on what they learned from the medium. For many years, digital research has been based on application programming interfaces (APIs) querying, an approach based on the extraction of records of data made available by the platforms through their programming interfaces. But what happens when the way to “follow the medium” changes? This contribution addresses the methodological challenges and the potential alternatives in research activities that affect the researchers' role due to recent restrictions. Two examples of research experience conducted before the APIs' closure are proposed in order to lead towards an initial reflection on its critical effects.

When the research process is viewed not merely as a set of methods for data collection and analysis but, instead, as an integrated series of arbitrary choices made by the researcher, it quickly becomes apparent that the prevailing conceptualization of rigor is much too narrow; indeed, the way rigor is currently conceptualized may well be responsible for the many errors that are commonly made in the research process. An expanded conceptualization of rigor is presented, and its implications for research into some critical health issues are discussed in some detail.

Today’s teenagers have a very close relationship with ICTs and the digital space related to them, as they have impacted the way the youth constructs their sense of self and the tools they use to perform their carefully constructed identity. One key element which influences the way one constructs their views by themselves is within the boundaries set by their biological sex and therefore through the behaviors associated with their asigned gender. Through the symbolic interactionist lense, or more specifically through Goffman's dramaturgical theory on the manner in which one presents him/herself in society, this paper looks at the manner in which teenagers use social media platforms and at the way they consume and create digital content in order to present their gender identity. The way teenagers consume and produce digital content differs and depends on how they interpret their ideals of femininity and masculinity, which are afterwards reproduced in the content they post on their social media pages. Therefore this research is an attempt to understand what are the factors teenagers take in account when consuming and producing content. What gender differences can be observed in regards to new media consumption? What difference can be observed in online activity behaviors between males and females? How do they feel about their gender identity concerning fitting in with their peer group? A mix-methodological approach was engaged in the data collection process. In the first stage of the research highschool students (n=324) from the city of Suceava (Romania) participated in taking an online survey. The initial intent was to meet with the young respondents in person, but due to the COVID-19 pandemic this was deemed impossible. For the second stage of data collection, six of the participants who took the online survey were invited to participate in a focus group designed to grasp a better understanding of the results from the previous stage. The discovered findings uncover engaging gender similarities and differences in social media consumption and the type, subject, matter and style in which they posted their content, but also in regards to the performance of the self between the online and offline space.
