This article presents the findings of the Society for Information Management’s 38th Anniversary IT Trends Study, with responses from IT executives in 793 organizations, including 495 CIOs. Positive trends endure, with IT budgets, salaries, hiring, and CIO time spent in the C-suite all up. The top five IT investments in 2018 were Analytics, Cybersecurity, Cloud, Software Development & Maintenance and ERP. CIOs’ top five most “worrisome” management issues were Cybersecurity, Talent, Perception of

Exploring theoretically plausible alternative models for explaining the phenomenon under study is a crucial step in advancing scientific knowledge. This paper advocates model selection in information systems (IS) studies that use partial least squares path modeling (PLS) and suggests the use of model selection criteria derived from information theory for this purpose. These criteria allow researchers to compare alternative models and select a parsimonious yet well-fitting model. However, as our

Wound healing is an important function of skin; however, after significant skin injury (burns) or in certain dermatological pathologies (chronic wounds), this important process can be deregulated or lost, resulting in severe complications. To avoid these, studies have focused on developing tissue-engineered skin substitutes (TESSs), which attempt to replace and regenerate the damaged skin. Autologous cultured epithelial substitutes (CESs) constituted of keratinocytes, allogeneic cultured dermal

Product reviews are critical high-scope non-marketing cues for consumers to obtain useful product information from various perspectives. However, the effects of inconsistent reviews among multiple sources on new product sales are underexplored. Based on the cue-diagnosticity framework, this research investigates how multi-source review inconsistency (MSRI) affects purchase intention and new product sales in the context of the U.S. automobile industry when firms signal product quality through adv

We examine the impact of product recalls on audit production. Product recalls are events that increase engagement risk associated with greater audit effort, and by extension, greater audit quality. Consistent with this conclusion, we find firm-years with a product recall have a lower likelihood of being subsequently restated and lower levels of accrual error. While a positive association generally exists between audit effort and audit fees, prior literature shows firms experiencing economic stre

ABSTRACT We investigate how investor sentiment influences investor demand for financial information. Using two separate settings—earnings announcements and acquisition announcements—we find that as sentiment decreases, investor demand increases for SEC‐regulated information that is highly detailed and relatively complicated to process. This result is consistent with psychology theory suggesting that during times of negative sentiment (i.e., pessimism), individuals are more likely to make decisio

Abstract Managers of at‐risk firms have incentives to prolong the life of the company or to extract personal wealth prior to firm liquidation, and they can pursue a number of activities in order to achieve these goals. Prior studies have investigated the consequences of managers becoming targets for acquisition. In this study, we examine the consequences of at‐risk firms doing the opposite: buying other firms (i.e., becoming at‐risk acquirers). We find two positive consequences of becoming at‐ri

The purpose of this study was to compare the location of the suture breakage between tying by hand vs with a safety clamp, needle driver. FiberWire No. 2 and 2-0 (Arthrex, Naples, Florida) were fastened onto the hook attachment of the digital force gauge. Sutures were placed under excessive strain using a hand tying technique vs a safety clamp, or instrument tying. Peak forces at which the sutures failed under tension along with locations of the suture breakage, measured from the site of the kno
