Internet Courses: Who Is Doing The Work?
The growth in Internet courses (E courses) and degrees is continuing but controls to insure academic honesty do not seem to be keeping pace with the growth in offerings. Responses to a questionnaire distributed to chairpersons of accounting departments relating to the use of controls for controlling academic dishonesty in E courses indicated that respondents strongly favored requiring students to provide a digital photo ID and audio capabilities when registering for an E course but rejected the idea of requiring them to provide a web cam that might be used for verifying their identity. Respondents strongly believe that students taking an E course should complete some, but not all, examinations on-line and, whenever possible, on the university web site and that they should complete some, but not all, homework assignments on-line and at the university web site whenever possible. They also tended to believe, even though they did not endorse requiring one, that students should use a web cam when completing examinations on-line and that faculty should compare the photo ID with the web cam image. However, they do not believe that students should be required to use a web cam when completing homework assignments or that faculty should compare the photo ID with the web cam image. Respondents believe that students should be required to participate in on-line chat rooms with both the instructor and with the instructor and other students. The use of a web cam and the comparison of a photo ID with a web cam image were not seen as desirable. Overall accounting chairs endorse requiring the student who enrolls in an E course to obtain some existing technology, except for a web cam, that might help control academic dishonesty. They expect the student to be prepared to spend more than $100 to obtain the technology
Analysis of The Town Officer (1791-1815): The earliest American treatise on municipal accounting?
Recent research has produced the earliest known treatise on Accounting written by an American. Samuel Freeman\u27s The Town Officer [1791] is significant in that it recommended double-entry fund accounting for municipalities. The paper analyzes and compares Freeman\u27s objectives of a plain and regular Method to modem municipal accounting concepts as articulated by the GASB. Additionally, the entries and the accounts recommended by Freeman are analyzed and compared to modern municipal accounting evidenced in current textbook material. These analyses show The Town Officer to be a significant contribution to accounting literature not only for its 1791 publication date, but also for the similarity of its content to present day municipal accounting objectives and requirements
The effect of BPIFA1/SPLUNC1 genetic variation on its expression and function in asthmatic airway epithelium
Bacterial permeability family member A1 (BPIFA1), also known as short palate, lung, and nasal epithelium clone 1 (SPLUNC1), is a protein involved in the antiinflammatory response. The goal of this study was to determine whether BPIFA1 expression in asthmatic airways is regulated by genetic variations, altering epithelial responses to type 2 cytokines (e.g., IL-13). Nasal epithelial cells from patients with mild to severe asthma were collected from the National Heart, Lung. and Blood Institute Severe Asthma Research Program centers, genotyped for rs750064, and measured for BPIFA1. To determine the function of rs750064, cells were cultured at air-liquid interface and treated with 11-13 with or without recombinant human BPIFA1 (rhBPIFA1). Noncultured nasal cells with the rs750064 CC genotype had significantly less BPIFA1 mRNA expression than the CT and TT genotypes. Cultured CC versus CT and TT cells without stimulation maintained less BPIFA1 expression. With IL-13 treatment, CC genotype cells secreted more eotaxin-3 than CT and TT genotype cells. Also, rhBPIFA1 reduced IL-13-mediated eotaxin-3. BPIFA1 mRNA levels negatively correlated with serum IgE and fractional exhaled nitric oxide. Baseline FEV1% levels were lower in the asthma patients with the CC genotype (n = 1,016). Our data suggest that less BPIFA1 in asthma patients with the CC allele may predispose them to greater eosinophilic inflammation, which could be attenuated by rhBPIFA1 protein therapy.NIH/NHLBI [R01HL125128, U10HL109257, UL1TR00448, U10HL109168]This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Genetic analyses identify GSDMB associated with asthma severity, exacerbations, and antiviral pathways
Background
The Chr17q12-21.2 region is the strongest and most consistently associated region with asthma susceptibility. The functional genes or single nucleotide polymorphisms (SNPs) are not obvious due to linkage disequilibrium.
Objectives
We sought to comprehensively investigate whole-genome sequence and RNA sequence from human bronchial epithelial cells to dissect functional genes/SNPs for asthma severity in the Severe Asthma Research Program.
Methods
Expression quantitative trait loci analysis (n = 114), correlation analysis (n = 156) of gene expression and asthma phenotypes, and pathway analysis were performed in bronchial epithelial cells and replicated. Genetic association for asthma severity (426 severe vs 531 nonsevere asthma) and longitudinal asthma exacerbations (n = 273) was performed.
Results
Multiple SNPs in gasdermin B (GSDMB) associated with asthma severity (odds ratio, >1.25) and longitudinal asthma exacerbations (P < .05). Expression quantitative trait loci analyses identified multiple SNPs associated with expression levels of post-GPI attachment to proteins 3, GSDMB, or gasdermin A (3.1 × 10−9 < P < 1.8 × 10−4). Higher expression levels of GSDMB correlated with asthma and greater number of exacerbations (P < .05). Expression levels of GSDMB correlated with genes involved in IFN signaling, MHC class I antigen presentation, and immune system pathways (false-discovery rate–adjusted P < .05). rs1031458 and rs3902920 in GSDMB colocalized with IFN regulatory factor binding sites and associated with GSDMB expression, asthma severity, and asthma exacerbations (P < .05).
Conclusions
By using a unique set of gene expression data from lung cells obtained using bronchoscopy from comprehensively characterized subjects with asthma, we show that SNPs in GSDMB associated with asthma severity, exacerbations, and GSDMB expression levels. Furthermore, its expression levels correlated with asthma exacerbations and antiviral pathways. Thus, GSDMB is a functional gene for both asthma susceptibility and severity
The Precision Interventions for Severe and/or Exacerbation-Prone (PrecISE) Asthma Network: an overview of Network organization, procedures and interventions
Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation prone asthma, who contribute disproportionately to disease burden. Extensive deep phenotyping has revealed the heterogeneous nature of severe asthma and identified distinct disease subtypes. A current challenge in the field is to translate new and emerging knowledge about different pathobiologic mechanisms in asthma into patient-specific therapies, with the ultimate goal of modifying the natural history of disease. Here we describe the Precision Interventions for Severe and/or Exacerbation Prone Asthma (PrecISE) Network, a groundbreaking collaborative effort of asthma researchers and biostatisticians from around the U.S. The PrecISE Network was designed to conduct phase II/proof of concept clinical trials of precision interventions in the severe asthma population, and is supported by the National Heart Lung and Blood Institute of the National Institutes of Health. Using an innovative adaptive platform trial design, the Network will evaluate up to six interventions simultaneously in biomarker-defined subgroups of subjects. We review the development and organizational structure of the Network, and choice of interventions being studied. We hope that the PrecISE Network will enhance our understanding of asthma subtypes and accelerate the development of therapeutics for of severe asthma
Ethics Principles, Personal Values, And Ethical Judgment
Researchers have conducted various studies in an attempt to gain insights into the ethics of business leaders to postulate possible reasons for unethical behavior. Recent scandals such as Enron, Worldcom, and Adelphia indicate an ethical problem still exists in the business community. Business ethics are typically discussed at length in university business programs, sometimes with one or more courses devoted to the topic. Very often students are used as surrogates for business leaders. One such study by Ahmad and Fadzly (A & F, 2004) posited that when a person observes what they consider to be an unethical act they will try to explain (ethical judgment) why the individual acted unethically. The person would then either endorse the action as acceptable in the circumstances or reject it as unacceptable. Their ethics principles and personal values would supposedly influence that decision. Additionally, the authors suggest that the perceived consequences of the unethical act would have an influence. This study is an attempt to replicate the A & F study, using accounting and business students in the United States (their study was conducted with Malaysian students). Ahmad and Fadzly’s questionnaire was modified and administered to 418 university business and accounting students. The questionnaire contained 19 questions, randomly arranged, that related to five factors. Respondents in the present study indicated a high level of ethics principles and personal values, and females displayed higher level personal values. The ethical judgment scale reflects the level of acceptance of (making excuses for) unethical acts and less than 20% of the participants in the present study indicated that they would agree that the unethical acts contained in the scale were acceptable in the environment described. Almost 60% of the respondents in the present study believed that they would experience positive consequences from unethical actions and a similar number, 56.13%, believed that they would experience negative consequences from unethical actions

Determinants of lung function across childhood in the Severe Asthma Research Program (SARP) 3.
BACKGROUND: Children with asthma are at risk for low lung function extending into adulthood, but understanding of clinical predictors is incomplete. OBJECTIVE: We sought to determine phenotypic factors associated with FEV1 throughout childhood in the Severe Asthma Research Program 3 pediatric cohort. METHODS: Lung function was measured at baseline and annually. Multivariate linear mixed-effects models were constructed to assess the effect of baseline and time-varying predictors of prebronchodilator FEV1 at each assessment for up to 6 years. All models were adjusted for age, predicted FEV1 by Global Lung Function Initiative reference equations, race, sex, and height. Secondary outcomes included postbronchodilator FEV1 and prebronchodilator FEV1/forced vital capacity. RESULTS: A total of 862 spirometry assessments were performed for 188 participants. Factors associated with FEV1 include baseline Feno (B, -49 mL/log2 PPB; 95% CI, -92 to -6), response to a characterizing dose of triamcinolone acetonide (B, -8.4 mL/1% change FEV1 posttriamcinolone; 95% CI, -12.3 to -4.5), and maximal bronchodilator reversibility (B, -27 mL/1% change postbronchodilator FEV1; 95% CI, -37 to -16). Annually assessed time-varying factors of age, obesity, and exacerbation frequency predicted FEV1 over time. Notably, there was a significant age and sex interaction. Among girls, there was no exacerbation effect. For boys, however, moderate (1-2) exacerbation frequency in the previous 12 months was associated with -20 mL (95% CI, -39 to -2) FEV1 at each successive year. High exacerbation frequency (≥3) 12 to 24 months before assessment was associated with -34 mL (95% CI, -61 to -7) FEV1 at each successive year. CONCLUSIONS: In children with severe and nonsevere asthma, several clinically relevant factors predict FEV1 over time. Boys with recurrent exacerbations are at high risk of lower FEV1 through childhood
Mixed Sputum Granulocyte Longitudinal Impact on Lung Function in the Severe Asthma Research Program.
Rationale: Some reports indicate longitudinal variability in sputum differential cell counts, whereas others describe stability. Highly variable sputum eosinophil percentages are associated with greater lung function loss than persistently elevated eosinophil percentages, but elevated neutrophils are linked to more severe asthma.Objectives: To examine sputum granulocyte stability or variability longitudinally and associations with important clinical characteristics.Methods: The SARP III (Severe Asthma Research Program III) cohort underwent comprehensive phenotype characterization at baseline and annually over 3 years. Adult subjects with acceptable sputum levels were assigned to one of three longitudinal sputum groups: eosinophils predominantly <2%, eosinophils predominantly ≥2%, or highly variable eosinophil percentages (>2 SDs determined from independent, repeated baseline eosinophil percentages). Subjects were similarly assigned to one of three longitudinal neutrophil groups with a 50% cut point.Measurements and Main Results: The group with predominantly <2% sputum eosinophils had the highest lung function (prebronchodilator FEV1% predicted, P < 0.01; FEV1/FVC ratio, P < 0.001) at baseline and throughout 3 years compared with other eosinophil groups. Healthcare use did not differ, although the highly variable eosinophil group reported more asthma exacerbations at Year 3. Longitudinal neutrophil groups showed few differences. However, a combination of predominantly ≥2% eosinophil and ≥50% neutrophil groups resulted in the lowest prebronchodilator FEV1% predicted (P = 0.049) compared with the combination with predominantly <2% eosinophils and<50% neutrophils.Conclusions: Subjects with predominantly ≥2% sputum eosinophils in combination with predominantly ≥50% neutrophils showed greater loss of lung function, whereas those with highly variable sputum eosinophils had greater healthcare use
