Business Process Agility

Business processes are the central building blocks of how individuals, organizations, and industries participate with one another. In a dynamic environment, a firm’s ability to respond and adapt is dependent on the agility of its business processes. However, agility from a business process perspective has yet to be defined and measured. This paper refines the definition of operational agility from the IS literature and tests a conceptual model. A field study is used to evaluate a metric created for measuring business process agility and understanding the relationship between the firm’s system capabilities and management’s factors driving adoption of agile business processes

Temporal Foraging Patterns of Nonnative Frogs (Eleutherodactylus Coqui) in Hawaii

The Puerto Rican Coqui Frog (Eleutherodactylus coqui) is a nocturnal, invasive species that was introduced into Hawaii in the 1980s. Because they reach extremely high densities (up to 90,000 frogs/ha), they have the potential to affect invertebrate prey communities. Previously, researchers used frogs collected only at night to characterize their prey. Because Coquis use retreat sites near the forest floor during the day and understory perch sites at night, frogs collected at night might show different amounts and types of prey than would frogs collected in the morning. We analyzed stomach contents of 435 frogs collected in the morning (0300–0600 h) and at night (1900–2200 h) from five sites on the island of Hawaii. Frogs collected in the morning had 1.7 times more prey items and 2.1 times greater prey volume than those collected at night; however, prey composition did not differ between morning- and evening-collected frogs. Across sites, Formicidae (ants) and Amphipoda (amphipods) were the dominant prey, and at least 61.6% of their prey items were nonnative species. Across sites, morning- and evening-collected stomach contents were not different from environmental samples of leaflitter invertebrates but were different from environmental samples of foliage and flying invertebrates, suggesting that Coquis forage primarily in the leaf litter throughout the night. Previous research that investigated stomach contents of frogs collected only at night greatly underestimated the number and volume of prey items that Coquis consume during the entire foraging period but accurately described their primary prey: nonnative, leaf-litter invertebrates

Invasive coqui frogs are associated with greater abundances of nonnative birds in Hawaii, USA

The global spread of invasive species has created significant challenges for avian conservation. Introduced predators and pathogens have long been recognized for their direct negative effects on birds, but introduced amphibians can reach high densities on islands with no native amphibians, where they interact with native species. The coqui frog (Eleutherodactylus coqui), introduced to the Hawaiian Islands in the late 1980s, could have significant impacts on birds because it is fully terrestrial and achieves high densities. Coquis have been hypothesized to compete with native birds for invertebrate prey, but could also serve as a novel food resource for birds that consume small vertebrates. To test whether coquis measurably affect bird abundance, we conducted point counts of birds in coqui-invaded and adjacent uninvaded plots across 15 sites on the island of Hawaii, USA. We used N-mixture models to estimate the effect of coqui presence and density on the abundances of both native and nonnative birds, while controlling for possible habitat differences between plots with and without coquis. We found that coquis were associated with ∼35% higher abundance of nonnative birds in general, and more specifically generalist birds that sometimes consume small vertebrates. We suggest that generalist birds increase in abundance with coquis primarily because coquis serve as an abundant food resource. While 4 native bird species co-occurred with coquis, native bird abundance (20% of our total observations) did not show a difference across coqui-invaded and uninvaded plots. Coquis do not appear to be important competitors with native birds in Hawaii, but the frogs are associated with increased abundances of some nonnative birds, which could induce undesirable ecosystem impacts

Learning Task Inventories (LTIs) in Introductory Organic Chemistry

University students who are capable of more accurate self-monitoring and self-assessment usually outperform less accurate students. Instructional support is an important tool that can be provided for learners to help them to understand that they should self-monitor and self-assess as well as how they should do this. To assist students in an introductory organic chemistry course in developing or improving self-monitoring and self-assessment skills, we offered scaffolding support through nine Learning Task Inventories (LTIs), completed weekly throughout one term. A class of 289 students were randomly assigned to one of 5 conditions (1 control = C1, and 4 experimental = E2-E5). Each group experienced a set of LTI conditions that differed with respect to feedback received and cognitive load. Specifically, participants in C1 received the LTIs. Condition E2 received LTIs and a metacognitive prompt. Conditions E3-E5 completed a learning quiz with different types of feedback: E3 received no feedback, E4 received brief feedback (i.e. The correct answer is A), and E5 received full feedback explaining specific answers. Participants also completed an introductory survey gathering important demographic information and an end-of-term survey assessing student reactions to the LTIs. Consistent with expectations, preliminary data support improved learning gains for reported test scores (F(2.86) = 4.48 value, p \u3c .02 ), such that students who received full feedback on their quizzes outperformed students who only completed the quiz. This presentation will present the results pertaining to student attitudes and the effects of treatment conditions on final exam grades

Introducing research initiatives into healthcare: What do doctors think?

Background: Current national and international policies emphasize the need to develop research initiatives within our health care system. Institutional biobanking represents a modern, large-scale research initiative that is reliant upon the support of several aspects of the health care organization. This research project aims to explore doctors' views on the concept of institutional biobanking and to gain insight into the factors which impact the development of research initiatives within healthcare systems. Methods: Qualitative research study using semi-structured interviews. The research was conducted across two public teaching hospitals in Sydney, Australia where institutional biobanking was being introduced. Twenty-five participants were interviewed, of whom 21 were medical practitioners at the specialist trainee level or above in a specialty directly related to biobanking; four were key stakeholders responsible for the design and implementation of the biobanking initiative. Results: All participants strongly supported the concept of institutional biobanking. Participants highlighted the discordance between the doctors who work to establish the biobank (the contributors) and the researchers who use it (the consumers). Participants identified several barriers that limit the success of research initiatives in the hospital setting including: the 'resistance to change' culture; the difficulties in engaging health professionals in research initiatives; and the lack of incentives offered to doctors for their contribution. Doctors positively valued the opportunity to advise the implementation team, and felt that the initiative could benefit from their knowledge and expertise. Conclusion: Successful integration of research initiatives into hospitals requires early collaboration between the implementing team and the health care professionals to produce a plan that is sensitive to the needs of the health professionals and tailored to the hospital setting. Research initiatives must consider incentives that encourage doctors to adopt operational responsibility for hospital research initiatives

The effect of body mass index on smoking behaviour and nicotine metabolism : a Mendelian randomization study

Given clear evidence that smoking lowers weight, it is possible that individuals with higher body mass index (BMI) smoke in order to lose or maintain their weight. We performed Mendelian randomization (MR) analyses of the effects of BMI on smoking behaviour in UK Biobank and the Tobacco and Genetics Consortium genome-wide association study (GWAS), on cotinine levels and nicotine metabolite ratio (NMR) in published GWAS and on DNA methylation in the Avon Longitudinal Study of Parents and Children. Our results indicate that higher BMI causally influences lifetime smoking, smoking initiation, smoking heaviness and also DNA methylation at the aryl-hydrocarbon receptor repressor (AHRR) locus, but we do not see evidence for an effect on smoking cessation. While there is no strong evidence that BMI causally influences cotinine levels, suggestive evidence for a negative causal influence on NMR may explain this. There is a causal effect of BMI on smoking, but the relationship is likely to be complex due to opposing effects on behaviour and metabolism.Peer reviewe
