Lifting student engagement in marketing classes

High levels of student engagement have been linked with better student learning outcomes, such as the quality of their output. With marketing students accounting for a high percentage of business school undergraduates, it is important that the level of engagement is determined and drivers of engagement identified. Marketing has traditionally been delivered in a teachercentric model, as opposed to a student-centric model which better encourages independent learning. Important aspects of the latter model are interactivity, active and collaborative learning, and enriching educational experiences. The author conducted focus groups with business students, and preliminary findings reveal that the instructor’s approach and the nature of the assignments do affect student engagement. A preliminary model of student engagement is proposed which will be tested in the quantitative research phase

Engaging students in marketing classes

High levels of student engagement have been linked with better student learning outcomes, such as the quality of their output. Marketing has traditionally been delivered in a teacher-centric model, as opposed to a student-centric model which better encourages independent learning. Important aspects of the latter model are interactivity, active and collaborative learning, and enriching educational experiences. The author has experimented with various aspects of his marketing classes and combined student feedback with findings from focus groups conducted with business students to derive a preliminary model of student engagement. The model was tested via quantitative research and initial analysis reveals tentative support for directly linking elements in the Lecturer’s Approach and Learning Support to the level of student engagement

Process intensification for post combustion CO₂ capture with chemical absorption: a critical review

The concentration of CO₂ in the atmosphere is increasing rapidly. CO₂ emissions may have an impact on global climate change. Effective CO₂ emission abatement strategies such as carbon capture and storage (CCS) are required to combat this trend. Compared with pre-combustion carbon capture and oxy-fuel carbon capture approaches, post-combustion CO₂ capture (PCC) using solvent process is one of the most mature carbon capture technologies. There are two main barriers for the PCC process using solvent to be commercially deployed: (a) high capital cost; (b) high thermal efficiency penalty due to solvent regeneration. Applying process intensification (PI) technology into PCC with solvent process has the potential to significantly reduce capital costs compared with conventional technology using packed columns. This paper intends to evaluate different PI technologies for their suitability in PCC process. The study shows that rotating packed bed (RPB) absorber/stripper has attracted much interest due to its high mass transfer capability. Currently experimental studies on CO₂ capture using RPB are based on standalone absorber or stripper. Therefore a schematic process flow diagram of intensified PCC process is proposed so as to motivate other researches for possible optimal design, operation and control. To intensify heat transfer in reboiler, spinning disc technology is recommended. To replace cross heat exchanger in conventional PCC (with packed column) process, printed circuit heat exchanger will be preferred. Solvent selection for conventional PCC process has been studied extensively. However, it needs more studies for solvent selection in intensified PCC process. The authors also predicted research challenges in intensified PCC process and potential new breakthrough from different aspects

Variable capture levels of carbon dioxide from natural gas combined cycle power plant with integrated post-combustion capture in low carbon electricity markets

This work considers the value of flexible power provision from natural gas-fired combined cycle (NGCC) power plants operating post-combustion carbon dioxide (CO2) capture in low carbon electricity markets. Specifically, the work assesses the value of the flexibility gained by varying CO2 capture levels, thus the specific energy penalty of capture and the resultant power plant net electricity export. The potential value of this flexible operation is quantified under different electricity market scenarios, given the corresponding variations in electricity export and CO2 emissions. A quantified assessment of natural gas-fired power plant integrated with amine-based post-combustion capture and compression is attempted through the development of an Aspen Plus simulation. To enable evaluation of flexible operation, the simulation was developed with the facility to model off-design behaviour in the steam cycle, amine capture unit and CO2 compression train. The simulation is ultimately used to determine relationships between CO2 capture level and the total specific electricity output penalty (EOP) of capture for different plant configurations. Based on this relationship, a novel methodology for maximising net plant income by optimising the operating capture level is proposed and evaluated. This methodology provides an optimisation approach for power plant operators given electricity market stimuli, namely electricity prices, fuel prices, and carbon reduction incentives. The techno-economic implications of capture level optimisation are considered in three different low carbon electricity market case studies; 1) a CO2 price operating in parallel to wholesale electricity selling prices, 2) a proportional subsidy for low carbon electricity considered to be the fraction of plant electrical output equal to the capture level, and 3) a subsidy for low carbon electricity based upon a counterfactual for net plant CO2 emissions (similar to typical approaches for implementing an Emissions Performance Standard). The incentives for variable capture levels are assessed in each market study, with the value of optimum capture level operation quantified for both plant operators and to the wider electricity market. All market case studies indicate that variable capture is likely to increase plant revenue throughout the range of market prices considered. Different market approaches, however, lead to different valuation of flexible power provision and therefore different operating outcomes

Factors That Impact the Success of Interorganizational Health Promotion Collaborations: A Scoping Review

© 2017, © The Author(s) 2017. Objective: To explore published empirical literature in order to identify factors that facilitate or inhibit collaborative approaches for health promotion using a scoping review methodology. Data Source: A comprehensive search of MEDLINE, CINAHL, ScienceDirect, PsycINFO, and Academic Search Complete for articles published between January 2001 and October 2015 was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study Inclusion and Exclusion Criteria: To be included studies had to: be an original research article, published in English, involve at least 2 organizations in a health promotion partnership, and identify factors contributing to or constraining the success of an established (or prior) partnership. Studies were excluded if they focused on primary care collaboration or organizations jointly lobbying for a cause. Data Extraction: Data extraction was completed by 2 members of the author team using a summary chart to extract information relevant to the factors that facilitated or constrained collaboration success. Data Synthesis: NVivo 10 was used to code article content into the thematic categories identified in the data extraction. Results: Twenty-five studies across 8 countries were identified. Several key factors contributed to collaborative effectiveness, including a shared vision, leadership, member characteristics, organizational commitment, available resources, clear roles/responsibilities, trust/clear communication, and engagement of the target population. Conclusion: In general, the findings were consistent with previous reviews; however, additional novel themes did emerge

Healthy Eating and Active Living: Rural-Based Working Men's Perspectives.

There is a pressing need for health promotion programs focused on increasing healthy eating and active living among "unreached" rural-based men. The purpose of the current study was to describe rural-based working men's views about health to distil acceptable workplace approaches to promoting men's healthy lifestyles. Two focus group interviews included 21 men who worked and lived in northern British Columbia, Canada. Interviews were approximately 2 hours in duration; data were analyzed using thematic analysis. Themes inductively derived included (a) food as quick filling fuels, (b) work strength and recreational exercise, and (c) (re)working masculine health norms. Participants positioned foods as quick filling fuels both at work and home as reflecting time constraints and the need to bolster energy levels. In the theme work strength and recreational exercise, men highlighted the physical labor demands pointing to the need to be resilient in overcoming the subarctic climate and/or work fatigue in order to fit in exercise. In the context of workplace health promotion programs for men, participants advised how clear messaging and linkages between health and work performance and productivity and cultivating friendly competition among male employees were central to reworking, as well as working, with established masculine health norms. Overall, the study findings indicate that the workplace can be an important means to reaching men in rural communities and promoting healthy eating and active living. That said, the development of workplace programs should be guided by strength-based masculine virtues and values that proactively embrace work and family life

Precise probing of residue roles by post-translational β,γ-C,N aza-Michael mutagenesis in enzyme active sites.

Biomimicry valuably allows the understanding of the essential chemical components required to recapitulate biological function, yet direct strategies for evaluating the roles of amino acids in proteins can be limited by access to suitable, subtly-altered unnatural variants. Here we describe a strategy for dissecting the role of histidine residues in enzyme active sites using unprecedented, chemical, post-translational side-chain-β,γ C-N bond formation. Installation of dehydroalanine (as a "tag") allowed the testing of nitrogen conjugate nucleophiles in "aza-Michael"-1,4-additions (to "modify"). This allowed the creation of a regioisomer of His (iso-His, Hi

Measurement and evaluation practices of factors that contribute to effective health promotion collaboration functioning: A scoping review

The purpose of this scoping review was to identify promising factors that underpin effective health promotion collaborations, measurement approaches, and evaluation practices. Measurement approaches and evaluation practices employed in 14 English-language articles published between January 2001 and October 2015 were considered. Data extraction included research design, health focus of the collaboration, factors being evaluated, how factors were conceptualized and measured, and outcome measures. Studies were methodologically diverse employing either quantitative methods (n = 9), mixed methods (n = 4), or qualitative methods (n = 1). In total, these 14 studies examined 113 factors, 88 of which were only measured once. Leadership was the most commonly studied factor but was conceptualized differently across studies. Six factors were significantly associated with outcome measures across studies; leadership (n = 3), gender (n = 2), trust (n = 2), length of the collaboration (n = 2), budget (n = 2) and changes in organizational model (n = 2). Since factors were often conceptualized differently, drawing conclusions about their impact on collaborative functioning remains difficult. The use of reliable and validated tools would strengthen evaluation of health promotion collaborations and would support and enhance the effectiveness of collaboration
