Presented a paper on Meta-analysis on Pair vs Solo Programming at the 2017 ACM SIGCSE Symposium

Paper Title:
A Meta-Analysis of Pair-Programming in Computer Programming Courses: Implications for Educational Practice.

Abstract:
Several experiments on the effects of pair programming versus solo programming in the context of education have been reported in the research literature. We present a meta-analysis of these studies that accounted for 18 manuscripts with 49 separate effect sizes in the domains of programming assignments, exams, retention, and affective measures. In total, our sample accounts for N=3308 students either using pair programming as a treatment variable or using traditional solo programming in the context of a computing course. Our findings suggest positive results in favor of pair programming across all four of the domains. We provide a comprehensive review of our results, and discuss our findings.

Presented a position paper on Data Analytics for Nonprofits at the 2017 SAIS Conference

Paper Title:
Data Analytics as a Conduit for Progressing Information Systems Research in Nonprofit Organizations

Abstract:
This position paper reviews the existing information systems (IS) research literature related to the nonprofit context and recommends how to significantly progress this research. The conducted literature review shows that very few studies have focused on nonprofit organizations (NPO). Our analysis indicates that IS researchers have investigated a limited number of issues in NPO contexts including potential research frameworks, strategic use of websites, the role of IS leadership, data management, IS adoption, IS use, and information security policies. Non-IS researchers have examined IS adoption, accountability, and social media usage. Studies that address IS use in the nonprofit context lack theoretical reasoning and empirical evidence; thus they cannot explain why and how effective and efficient use of IS can help NPOs achieve their mission goals. In order to motivate and advance our knowledge of the nonprofit context, we present data analytics as an area in which IS researchers could focus as a future path. We suggest ways that IS researchers can apply their expertise in non-NPO contexts to the NPO context.

Presented a paper on Collaborative Information Seeking at the 2016 International Conference on Collaboration Technologies and Systems (CTS)

Paper Title:
A Research Plan to Study Impact of a Collaborative Web Search Tool on Novice's Query Behavior

Abstract:
In the past decade, research efforts dedicated to studying the process of collaborative web search have been on the rise. Yet, limited number of studies have examined the impact of collaborative information search process on novice’s query behaviors. Studying and analyzing factors that influence web search behaviors, specifically users’ patterns of queries when using collaborative search systems can help with making query suggestions for group users. Improvements in user query behaviors and system query suggestions help in reducing search time and increasing query success rates for novices. In this paper, we present an empirical study plan designed to investigate the influence of collaboration between experts and novices as well as use of a collaborative web search tool on novice’s query behavior. In this research-in-progress study, we intend to use SearchTeam as our collaborative search tool. The results of this study are expected to provide information that could help collaborative web search tool designers to find ways to improve the query suggestions feature for group users. Additionally, this study will test the hypothesis that – having domain experts working with non-experts using collaborative search systems would immensely increase the query success rates for non-expert users, and help them learn querying strategies over the course of time. If the above hypothesis is proven, then use of collaborative web search tools during training of interns would be highly recommended.

Presented a Paper on IT Standards and Participated in Panel Discussions on Big Data Analytics and Service Computing at the 2015 Workshop on e-Business (WeB)

Paper Title:
Investigating IT Standardization Process through the lens of Theory of Communicative Action

Abstract:
Developing standards is a social practice wherein experts engage in discussions to evaluate design solutions. In this paper, we analyze processes followed to develop SOAP standard from the theory of communicative action
perspective, which argues that individuals engaged in social discourse would exhibit five possible actions: instrumental, strategic, normatively regulated, dramaturgical, and communicative. Our findings reveal that participants in standardization processes engage in communicative action most frequently with aim of reaching mutual understanding and consensus, engage in strategic action when influencing others towards their intended goals, engage in instrumental action when taking responsibility for solving technical issues, engage in dramaturgical action when expressing their opinions, and engage in normatively regulated action when performing roles they assumed. Our analysis indicates that 60% of activities performed are consensus oriented whereas the rest are success oriented. This paper provides empirical evidence for Habermasian view of social actions occurring in the standardization process setting.

Presented a paper on Nonprofit Organization IT adoption and usage at AMCIS 2015

Paper Title:
A Preliminary Study of Information Technologies Usage in Nonprofit Organizations

Abstract:
In this paper, we present the results of a preliminary survey study to examine the ways in which regional nonprofit organizations (NPOs) in the U.S. adopted and utilized information technologies. The majority of the survey respondents (72.5%) consists of small to medium sized NPOs. The survey findings reveal that most responding organizations don’t have a technology plan even though they consider information technology as an important driving force to achieve organizational missions. A pragmatic approach that adopts mature, proven technologies is the most common approach followed by the respondents. Our findings also provide some empirical insights on how NPOs perform different technological tasks, manage data, and exploit web capabilities.

Paper on Conceptual Model of Website Design Elements that Influences Credibility and Trustworthiness accepted at the 2015 SAIS Conference

Paper title: Conceptual Model of Website Design Elements that Influences Credibility and Trustworthiness

Abstract:
In today’s competitive environment, it is important for web designers to understand what design elements are essential for attracting visitors, making the visitor trust the website, and perform intended actions like placing an order and revisiting the site.  Trustworthiness of a website heavily relies on a good first impression and visitor’s visual perception of the user interface. Therefore, the focus of this research is to investigate the effects of visual design elements on trustworthiness of a site. In this research-in-progress paper, we develop a conceptual model to depict the relationships among website design elements and trustworthiness. This conceptual model aids website designers understand what elements are appealing to the visual senses, and conjures credibility and trust.

Paper on Review of Web Service Specifications for Long-running Conversations accepted at the CONISAR 2014

Paper title: Review of Web Service Specifications for Long-running Conversations

Abstract:
Despite the growing number of standards and interest in web services, support for implementation of long-running conversations is inadequate. Most real world business transactions typically consists of series of business activities. Such transactions originate from different sources which have multiple web services running to achieve a specific result. In this paper, we provide an overview of long-running conversation properties, and a review of relevant web service specifications. Our analysis indicates that WS-Coordination and WS-BusinessActivity specifications are the best option for implementing long-running conversations using web services.
