Streptomyces tardus sp. nov.: A Slow-Growing Actinobacterium Producing Candicidin, Isolated From Sediments of the Trondheim Fjord
Marine environments are home to an extensive number of microorganisms, many of which remain unexplored for taxonomic novelty and functional capabilities. In this study, a slow-growing Streptomyces strain expressing unique genomic and phenotypic characteristics, P38-E01T , was described using a polyphasic taxonomic approach. This strain is part of a collection of over 8,000 marine Actinobacteria isolates collected in the Trondheim fjord of Norway by SINTEF Industry (Trondheim, Norway) and the Norwegian University of Science and Technology (NTNU, Trondheim, Norway). Strain P38-E01T was isolated from the sediments of the Trondheim fjord, and phylogenetic analyses affiliated this strain with the genus Streptomyces, but it was not closely affiliated with other described species. The closest related type strains were Streptomyces daliensis YIM 31724T (98.6%), Streptomyces rimosus subsp. rimosus ATCC 10970T (98.4%), and Streptomyces sclerotialus NRRL ISP-5269T (98.3%). Predominant fatty acids were C16V0 iso, C16V0, and Summed Feature 3, and the predominant respiratory quinones were MK-10(H6), MK-10(H4), and MK9(H4). The main polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, hosphatidylglycerol, and phosphoglycolipid. The whole-cell sugars were glucose, ribose, and in minor amounts, mannose. The cell wall peptidoglycan contained LL-diaminopimelic acid. The draft genome has a size of 6.16 Mb, with a %G C C content of 71.4% and is predicted to contain at least 19 biosynthetic gene clusters encoding diverse secondary metabolites. Strain P38-E01T was found to inhibit the growth of the pathogenic yeast Candida albicans ATCC 90028 and a number of Gram-positive bacterial human and plant pathogens. Metabolites extracted from cultures of P38-E01T were analyzed by mass spectrometry, and it was found that the isolate produced the antifungal compound candicidin. Phenotypic and chemotaxonomic signatures, along with phylogenetic analyses, distinguished isolate P38-E01T from its closest neighbors; thus, this isolate represents a novel species of the genus Streptomyces for which the name Streptomyces tardus sp. nov. (P38-E01T D CCM 9049T D DSM 111582T ) is proposed.publishedVersio
Study Protocol of a factorial trial ECHO: Optimizing a group-based school intervention for children with emotional problems
Background - Youth mental health problems are a major public health concern. Anxiety and depression are among the most common psychological difficulties. The aim of this study is to evaluate an optimized version of a promising indicated group intervention for emotional problems. The program (EMOTION Coping Kids Managing Anxiety and Depression) targets school children 8â12 years with anxious and depressive symptoms and examines three factors. Factor 1 compares the standard EMOTION intervention delivered in 16 group-based sessions (Group), versus a partially-digital EMOTION intervention (DIGGI) delivered as eight group sessions and eight digital sessions. Both versions use virtual reality technology (VR) to improve behavioral experiments. Factor 2 compares parent participation in a 5-session parent group (high involvement) versus sharing information with parents via a brochure (low involvement). Factor 3 compares the use of a measurement and feedback system (MFS) designed to help group leaders tailor the intervention using feedback from children with no MFS.
Methods - Using a cluster-randomized factorial design, 40 schools across Norway will be randomized to eight different experimental conditions based on three, two-level factors. To assess internalizing symptoms in children, children and their parents will be given self-report questionnaires pre-, post-, and one year after intervention. Parents also report on demographics, user satisfaction, personal symptoms and perception of family related factors. Teachers report on child symptoms and school functioning. Group leaders and the head of the municipal services report on implementation issues. The primary outcomes are changes in depressive and anxious symptoms. Some secondary outcomes are changes in self-esteem, quality of life, and user satisfaction. Questions regarding the consequences of the COVID-19 pandemic are included. Treatment fidelity is based on checklists from group leaders, and on user data from the participating children.
Discussion - This study is a collaboration between three regional centers for child and adolescent mental health in Norway. It will provide knowledge about: (1) the effect of school-based preventive interventions on anxiety and depression in children; (2) the effect of feedback informed health systems, (3) the effect and cost of digital health interventions for children, and (4) the effect of parental involvement

Do Perceptions of Fairness Mitigate Managersâ Use of Budgetary Slack During Asymmetric Information Conditions?
Prior research demonstrates a positive relationship between information asymmetry and managersâ use of budgetary slack and thereby suggests that minimizing managersâ private information is a potential tactic for reducing slack in budgets. Asymmetric information, however, often cannot be avoided when specialized technical expertise is required to operate a particular responsibility area. This study contributes to the literature by investigating whether favorable perceptions of fairness mitigate managersâ use of budgetary slack during participative environments in which managers hold private information. Overall, the findings demonstrate the benefits of fair budgeting practices. In particular, survey results suggest that the presence of budgetary slack in efficiency targets is lower for managers who hold favorable fairness perceptions. A gender effect is also demonstrated between perceptions of fairness and the presence of budgetary slack in spending targets. Factor analytical evidence toward the development of a more refined measure of budgetary slack is provided
The Influence of Fairness Perceptions and Goal Commitment on Managers\u27 Performance in a Budget Setting
Recent budgeting research suggests that fairness perceptions play a role in performance. In particular, prior work demonstrates a positive relation between fairness and performance during budgeting. The process by which fairness perceptions translate into improved performance, however, remains unaddressed. This study contributes to the accounting literature by investigating whether fairness perceptions improve performance via participation by increasing managers\u27 commitment to budgetary goals. Structural equation models are proposed in which both fairness perceptions and goal commitment influence managers\u27 performance during budgeting. Questionnaire data collected from one field site in the midst of downsizing were used to test the models. The results suggest that increased participation during budgeting fosters a sense of fairness, which, in turn, increases managers\u27 commitment to budgetary goals and subsequently enhances performance ratings. The direct path between fairness perceptions and performance, however, appears to be insignificant when goal commitment is considered
New Linkages: Integrating Managerial Accounting and Fundamentals of Financial Management
The influence of attributions and budget emphasis on framing and risk preferences under conditions of unfavorable budget variances
The purpose of this study is to examine the influence of causal attributions and budget emphasis on individuals\u27 framing perceptions and risk preferences under conditions of unfavorable budget variances. Prospect theory maintains that risk preferences are domain-specific; individuals tend to be risk-averse in gains and risk-seeking in losses. Prior accounting research has found that while individual actions clearly reflect prospect theory propositions during situations of gain, individuals demonstrate risk indifference when faced with situations of loss. We investigate potential explanations for this lack of strict adherence to prospect theory during situations of loss. Our study uses internal and external attributions and pressure to meet budget targets for performance appraisals to create salient loss conditions. The results demonstrate that budget decisions vary depending on the casual factors of the unfavorable variance and on the degree of emphasis placed on achieving time budget targets. As expected, subjects exhibited relatively more risk seeking behavior when faced with internal attributions and when they expected a greater emphasis on meeting budgetary goals in performance assessment. Our results also demonstrate the importance of controlling for framing effects in prospect theory related tests
A Service Learning Approach to Teaching CVP Analysis in Cost Accounting
This chapter describes a service learning (SL) project implemented in an upper-level undergraduate Cost Accounting course to enhance the coverage of costing concepts. Employing a variation of Lafond, Leauby, and Wentzel (2017) SL task, students actively gather cost data for a business venture by preparing peanut butter and jelly sandwiches which are then donated to a local soup kitchen. Comparison of scores on pre- and post-tests suggests that the SL assignment enhances studentsâ understanding of key cost accounting concepts. More specifically, improvements in mean post-test scores proved significantly greater in the experimental group after completion of the SL activity than in the control group. Feedback further suggests that students appreciated the opportunity to engage in SL by helping others less fortunate. Active SL tied to course objectives meets The Association to Advance Collegiate Schools of Business (AACSB, 2013) suggestions for honing studentsâ critical thinking skills, while also helping to instill SL values in future business leaders
Cost Accumulation in Small Businesses: Experiential Learning Project
Purpose: The subject area of the assignment is cost accumulation. This instructional tool enhances coverage of cost accumulation topics in graduate level Introductory to Management Accounting courses.
Methodology/approach: The assignment entails visiting a small business and interviewing the owner to learn about the companyâs process for determining costs of products and/or services. Such active learning hones leadership and critical thinking skills by requiring students to employ interviewing and listening techniques as they act as business advisors to discuss cost accumulation processes with small business owners. The assignment provides flexibility since a range of business types can be used from a landscaping business operated out of oneâs garage to a mid-size manufacturing company.
Findings: Students see how a small business accumulates costs and gain experience analyzing the effectiveness of cost accumulation systems and providing recommendations.
Practical implications: A list of supplementary materials is included, covering teaching notes, assessment data, and grading rubrics.
Originality/value: Student feedback suggests that students value the opportunity to engage in a realistic exercise that allows them to draw linkages between textbook material and the real world, while also acting in a consulting role to apply class concepts to small businesses. Furthermore, assessment data based on grading rubrics indicate that all students meet or exceed instructor expectations, thus increasing the viable use of this course project
Encouraging service learning and entrepreneurial thinking: PB&J sandwiches in a managerial accounting course
This paper describes an easy-to-implement service learning project developed to enhance the coverage of costing concepts in an introductory Managerial Accounting course. The course-specific assignment utilizes an entrepreneurial scenario which requires students to examine the viability of opening a sandwich stand in the student union. Students actively gather cost data for their business venture by preparing peanut butter and jelly sandwiches which are then donated to a local soup kitchen. Comparison of scores on pre- and post-tests suggests that the service learning assignment enhances studentsâ understanding of key managerial accounting concepts. More specifically, improvements in mean post-test scores proved significantly higher in the experimental group after completion of the service learning activity than in the control group. Feedback further suggests that students appreciated the opportunity to engage in service learning by helping others less fortunate and that the project encouraged them to think entrepreneurially
