The literature on formative modelling (“formative measurement”) in the information systems discipline claims that measurement model misspecification, where a reflective model is used instead of a more appropriate formative model, is widespread. In this research, we argue that this cannot be true because models misspecified in this way would fail th...

Computer self-efficacy (CSE) has captured the interest of researchers from widely diverse knowledge domains for over four decades. During that time, the realm of computer adoption and use has evolved and flourished. Along with this evolution, our understanding of CSE, its utility in behavior modeling and training development, and its relationship t...

AI has paved the way to an unprecedented pace of change in work processes across several industries. As individuals and organizations increasingly employ AI to improve performance, investigating the link between AI-enabled systems characteristics, AI reliance, and resulting performance benefits remains largely overlooked in IS research so far. The...

While there is a proliferation of research on emotion detection, little research has focused on emotion induction in HCI literature. We propose an emotion-induction model that points out the two fundamental design goals (i.e., sensemaking vs. exploration) as antecedents of the four different types of emotions, which, in turn, introspectively reinfo...

Even though there is a rich and extensive literature on the individual adoption of technologies, limited attention has been placed on the choice of one among competing alternatives, which the authors posit as an essential antecedent to the individual acceptance decision that has been considered in the past. In this chapter, they compare two levels...

This study develops a technology category framework to enable the investigation of a possible moderating effect of technology type on adoption behavior by extracting and analyzing the technology descriptions from 950 papers covering over 20 years of technology acceptance research. We utilize both human judgment and statistical techniques by using t...

One of the central assumptions of the causal indicator literature is that all causal indicators must be included in the model and that the exclusion of one or more relevant causal indicators would have severe negative consequences by altering the meaning of the latent variable. In this research we show that the omission of a relevant causal indicat...

Researchers surveyed software professionals on their views regarding the effectiveness of pair programming compared to traditional solo programming. The survey produced three main findings. First, the respondents believed that project complexity and pair composition (the individual programmers' expertise and pair-programming experience) affect pair...

Information systems researchers have recently begun to propose models that include formatively specified constructs, and largely rely on partial least squares (PLS) to estimate the parameters of interest in those models. In this research, we focus on those cases where the formatively specified constructs are endogenous to other constructs in the re...

We appreciate the interest shown by Rigdon et al. [Rigdon EE, Becker J-M, Rai A, Ringle CM, Diamantopoulos A, Karahanna E, Straub DW, Dijkstra TK (2014) Conflating antecedents and formative indicators: A comment on Aguirre-Urreta and Marakas. Inform. Systems Res. 25(4):780-784.] in our recent work and for the time and effort spent in carefully cons...

The accurate estimation of reliability is of great importance to the conduct and interpretation of empirical research as it is used to judge the quality of reported research, often plays a role in publication decisions, and is a key element of meta-analytic reviews. When employing partial least squares (PLS) as the method of analysis, the reliabili...

In this chapter, they compare two levels...

Researchers in a number of disciplines, including Information Systems, have argued that much of past research may have incorrectly specified the relationship between latent variables and indicators as reflective when an understanding of a construct and its measures indicates that a formative specification would have been warranted. Coupled with the...

In this paper, the authors conduct a study to explore the evaluation and choice between candidate software applications. Using business professionals, technology adoption is investigated by presenting participants with an alternative choice set using software applications relevant to the professional domain of the subjects. Results from this study,...

Research examining the formative specification of constructs has highlighted the need for researchers to capture all relevant causes of a construct of interest. However, the consequences of omitting a formative indicator have not been thoroughly examined. Given that one of the commonly employed techniques for modeling formatively specified construc...

This study aimed to answer two research questions. First, is pair programming more cost effective than solo programming in all situations? Second, in what situations is pair programming more cost effective than solo programming? We adopted and extended economic models specified by prior researchers. We examined two different scenarios and conducted...

The study investigates the mediating role of emotional states and perceived interactivity in the formation of preference for website by revisiting the Landscape Preference Model (LPM) recently introduced to IS literature (Kaplan 1988; Singh, Dalal et al. 2005; Singh, Todd Donavan et al. 2008; Lee and Kozar 2009). We hypothesize that, in HCI context...

A recent development in the technology acceptance literature is the inclusion of gender as a moderator of the relationships between intention and its antecedents, such that some are stronger for men than women, and vice versa. While the effects have been well established, the mechanisms by which they operate, that is, which specific gender differen...

To investigate a generalizable moderating effect of the type of technology tested upon its acceptance, a classification of technologies is needed. This study aims to develop a preliminary framework to describe information technologies based upon 200 randomly selected technology descriptions taken from a comprehensive TAM meta-analysis effort curren...

Usability flaws found in the later stages of the software development process can be extremely costly to resolve. Accordingly, usability evaluation (UE) is an important, albeit usually expensive, part of development. We report on how the inexpensive UE method of heuristic evaluation (HE) can benefit from collaborative software (CSW), implicit coord...

This study aims to answer the following research question: compared to solo programming, is pair programming a more cost effective method for developing software? This paper proposes a research model based on theories and previous empirical studies. It discusses a multi-study approach to address the question in hand. The first study is a survey of...

The empirical literature comparing entity relationship and object-oriented modeling techniques, while vibrant, has often yielded equivocal findings. This review employs Norman's (1986) Theory of Action to distinguish between model creation and comprehension studies, and applies and extends the theoretical framework proposed by Gemino and Wand (2004...

Using data from 1216 students and professionals, this research developed a new construct focusing on beliefs about the social role and capabilities of computing technology, the computing technology continuum of perspective (CP). Results indicated that individuals have different beliefs about the social role and capabilities of computing technology...

Partial Least Squares (PLS) is a popular technique with extensive adoption within the Information Systems research community. However, the statistical performance of PLS has not been extensively studied, and recent research has questioned some of its purported advantages. The simulation study reported here analyzed the performance of PLS with regar...

Technology acceptance is one of the most extensive streams of research in the information systems literature. Building on previous work, it has recently been proposed that the gender of information system users moderates the relationships between intention to use a technology and its most important determinants, perceived usefulness and perceived e...

Partial Least Squares (PLS) has become an increasingly popular approach to testing research models with multiple proposed causality links. Moreover, recent interest in the specification of constructs in a formative manner has accentuated this tendency, given the purported ability of PLS to handle this methodological development. While a review of t...

Requirements elicitation has been recognized as a critical stage in system development projects, yet current models prescribing particular elicitation techniques are still limited in their development and application. This research reviews efforts aimed at addressing this issue, and synthesizes a common structure consisting of project contingencies...

Researchers have found that some system design activities for users are effective in terms of satisfaction and commitment (13), user involvement and user attitude (12) and performance (12, 13). As Markus and Mao (19) suggest, activities in different stages of the life cycle and participants should be clearly defined and studied. Many researchers (7...

A debate exists as to whether social cues should be intentionally designed into the user interface. Some have argued that such interfaces will improve comfort with the interface, create a more natural interaction and improve productivity, although others have argued that these interfaces will lead individuals to ascribe characteristics and responsi...

The question of why individuals adopt a particular information system is an important issue in IS research. While extensive prior research has established that the Technology Acceptance Model (TAM) (1) does a good job of predicting a user's intention to adopt an information system through the constructs Perceived Ease of Use (PEOU) and Perceived Us...

Commitment to an information system (IS) development project is essential for system success. However, some projects exhibit escalation of commitment, i.e. allocation of additional resources to a failing course of action. This paper describes two simulated longitudinal experiments examining the effects of project, psychological, social, and structu...

Advances in information and communication technologies have fueled rapid growth in the popularity of technology-supported distributed learning (DL). Many educational institutions, both academic and corporate, have undertaken initiatives that leverage the myriad of available DL technologies. Despite their rapid growth in popularity, however, alterna...

Recent empirical work by Compeau and Higgins (1995) investigated the role of behavioral modeling training in the development of computer skills. Their efforts have provided insight into our understanding of the role of computer self-efficacy (CSE) and behavioral modeling (BM) techniques with regard to training effectiveness. Contrary to their expec...

This paper explores the use of metaphorical personification (anthropomorphism) as an aid to describing and understanding the complexities of computing technologies. This common and seemingly intuitive practice (it “reads”, “writes”, “thinks”, “is friendly”, “catches and transmits viruses”, etc.) has become the standard by which we formulate our dai...

Despite the recent empirical interest and advances in research with regard to the construct of computer self-efficacy (CSE), the results obtained to date have, in some cases, been either equivocal or contradictory. We suggest that such results may be attributable to a general lack of attention to the dynamic, multileveled, and multifaceted nature o...

The determination of information requirements is one of the most crucial stages in the software design and development process (Montezemi 1988). It is during this stage that the greatest degree of interaction occurs between the analyst and the user (Lauer et al. 1992). Despite the system development method employed, the functional success of many a...

This paper reports the results of a controlled laboratory experiment in which the work of Elam and Mead (Elam, J. J., M. Mead. 1990. Can software influence creativity? Inform. Systems Res. 1(1) 1--23.) was both replicated and extended to explore how knowledge and use of a creativity-enhancing process employed both manually and delivered via compute...

A major postulate in many theoretical perspectives of information technology (IT) implementation is the rational assumption that resistance to change is an observable behaviour and that it is mutually exclusive of supportive behaviour. This perspective assumes that any resistance manifesting itself in a covert manner is generally dysfunctional and...

Information technology will be the most pervasive and important influence on individuals and organizations in the next 10 years. Impression management is a growing field of study in the management and organizational sciences, which studies the self-presentational approach of individuals and the organizations. This collection of papers is both explo...

Conceptual data modelling (CDM) refers to the phase of the information systems development process that involves the abstraction and representation of the real world data pertinent to an organization. When CDM is properly and rigorously performed, the delivered system is expected to be functionally richer, less error-prone, more fully attuned to me...

This paper describes an approach to DSS design and use intended to enhance the development of both general and specific problem-solving skills of the user by encouraging the use of discovery as a tool for learning. The basic philosophy of discovery learning, often referred to as errorful learning, is to present the user with a microworld in which t...
