Sustainability Intelligence (SI): A Journey, Not a Destination
No full textThis article, Sustainability Intelligence (SI): A Journey, Not a Destination – A Response to Professor Gail A. Rowntree, addresses the evolving nature of sustainability in organizations. The author, Gurpreet Singh, PhD Candidate at Buckinghamshire New University, responds to a key question posed by Professor Rowntree at the BNU Research and Enterprise Conference 2024: "When is an organization truly sustainable?" Singh argues that sustainability is not a finite goal but an ongoing system of continuous learning, reflection, and adaptation, rooted in systemic thinking. Using the SINGH (Synthesis in Navigation Gathering Holistic view) framework, the article discusses how organizations can embed sustainability into their business models and decision-making processes to navigate complex challenges. This response highlights the importance of adopting a mindset that views sustainability as an iterative process rather than a fixed destination
Stable and efficient Li-ion battery anodes prepared from polymer-derived silicon oxycarbide-carbon nanotube shell/core composites
No full textWe demonstrate synthesis and electrochemical performance of polymer-derived silicon oxycarbide-carbon nanotube (SiOC-CNT) composites as a stable lithium intercalation material for secondary battery applications. Composite synthesis was achieved through controlled thermal decomposition of 1,3,5,7-tetramethyl 1,3,5,7-tetravinyl cyclotetrasiloxane (TTCS) precursor on carbon nanotubes surfaces that resulted in formation of shell/core type ceramic SiOC-CNT architecture. Li-ion battery anode (prepared at a loading of~ 1.0 mg cmˉ²) showed stable charge capacity of 686 mAh gˉ¹ even after 40 cycles. The average coulombic efficiency (excluding the first cycle loss) was 99.6 %. Further, the post electrochemical imaging of the dissembled cells showed no apparent damage to the anode surface, highlighting improved chemical and mechanical stability of these composites. Similar trend was observed in the rate capability tests, where the SiOC-CNT anode (with 5 wt.% loading in TTCS) again showed stable performance, completely recovering the first cycle capacity of ~ 750 mAh gˉ¹ when the current density was brought back to 50 mA gˉ¹ after cycling at higher current densities
MoS2/graphene composite paper for sodium-ion battery electrodes.
No full textWe study the synthesis and electrochemical and mechanical performance of layered freestanding papers composed of acid-exfoliated few-layer molybdenum disulfide (MoS₂) and reduced graphene oxide (rGO) flakes for use as a self-standing flexible electrode in sodium-ion batteries. Synthesis was achieved through vacuum filtration of homogeneous dispersions consisting of varying weight percent of acid-treated MoS₂ flakes in GO in DI water, followed by thermal reduction at elevated temperatures. The electrochemical performance of the crumpled composite paper (at 4 mg cm⁻²) was evaluated as counter electrode against pure Na foil in a half-cell configuration. The electrode showed good Na cycling ability with a stable charge capacity of
approximately 230 mAh g⁻¹ with respect to total weight of the electrode with Coulombic efficiency reaching approximately 99%. In addition, static uniaxial tensile tests performed on crumpled composite papers showed high average strain to failure reaching approximately 2%

Gurpreet is an assistant professor at the Indian Institute of Management, Shillong. Her research interests include destination barnding and destination governance. Destination image has been an important topic in tourism research. The appeal of a destination’s image can contribute to a destination’s competitiveness. A wide range of factors contribute to the strength of the destination image, and the value extends beyond consumers to destination stakeholders. While a range of issues around destination image have been examined, there remains much to be explored. There is a paucity of research on the value created for these stakeholders by the brand image. There is also a gap in our understanding of the impact of destination image on destination stakeholder behavior. It is anticipated that operators in destinations with an image that emphasizes nature, and the environment will be more likely to undertake environmentally sustainable activities. This study aims to understand how the stakeholder perceives the value of the destination image and the impact of image considerations on stakeholders' actions in a destination

No full textAchieving operational excellence in service sector using lean six sigma
No full textLean Six Sigma is a process improvement methodology that has been used in several industries and sectors for years. Even though Lean and Six Sigma come from distinct backgrounds, over a period of time, they have been used in conjunction with each other by companies to solve problems, increase efficiency and reduce waste in the processes. In the traditional schema of things, Lean Six Sigma methodology is more commonly used in a manufacturing setting. Further, the impact of organizational culture and leadership style is often ignored in the deployment of Lean Six Sigma methodologies. The objective of this dissertation is to study the impact of organizational culture and leadership styles on the deployment of Lean Six Sigma and its outcomes in a service sector. In particular, this research focuses on Healthcare sector. In Chapter 1, we provide an introduction to Lean and Six Sigma and provide an insight into the evolution of the methodology from Quality Management.

Name Recognition to Identify Patients of South Asian Ethnicity within the Cancer Registry
No full textObjective: The goal of this project was to develop a list of forenames and surnames of South Asian (SA) women that could be used to identify SA breast cancer patients within the cancer registry. This list was compiled, evaluated, and validated to ensure comprehensiveness, accuracy, and applicability of SA names. Methods: This project was conducted by Canadian researchers who are immersed in conducting behavioral studies with SA women diagnosed with cancer in the province of British Columbia. Recruiting SA cancer patients for research can be a difficult task due to social and cultural factors. Methods used by other researchers to identify ethnicity related unique names were employed to filter surnames and forenames that were not common to this ethnic group. Co-author (Gurpreet Oshan) of SA ethnicity rigorously identified and deleted multiple lists and redundant entries along with common English forenames which resulted in a list of 16,888 SA forenames. All co-authors of Indian ethnicity (Gurpreet Oshan, Savitri Singh-Carlson, Harajit Lail) were involved in critiquing and manually reviewing the names list throughout this process. Comprehensive lists of SA surnames and women′s forenames were reviewed to identify those that were unique to SA ethnicity. Accuracy was ensured by constantly filtering the redundancy by using an Excel program which helped to illustrate the number of times each name was spelled in different ways. Results: The final lists included 9112 surnames and 16,888 forenames of SA ethnicity. On the basis of the surname linkage only, the sensitivity of the list was 76.6%, specificity was 62.9%, and the positive predictive value was 58.5%. On the basis of both the surname and forename linkage, the specificity of the list was 88.6%. These lists include variations in spelling forenames and surnames as well. Conclusions: The list of surnames and forenames can be useful tools to identify SA ethnic groups from large population database in healthcare-related research. Ethnicity-specific population research is important in order to help identify how cancer care should be delivered for the SA population, as well as for planning and provision of other related health services. We are willing to share this list upon request to the authors
Bringing It All Back Home: Boulware and the Unfortunate Demise of the Miller Rule
No full textIn this Note, the author addresses the underlying tension between criminal intent and the complexity of the tax code in criminal tax prosecution in light of the recent Supreme Court opinion in U.S. v. Boulware. The author takes a look at the facts and circumstances of Boulware, the body of precedent supporting the Ninth Circuit\u27s opinion, and the reasoning of the Supreme Court in its subsequent reversal of that opinion. He revisits the oft cited opinion of Judge Learned Hand in Helvering v Gregory, and asks whether the courts have taken Judge Hand\u27s famous approval of tax planning so far out of context that it justifies the very behavior that he reproved. The author then asks if it is time to do away with the actual tax deficiency requirement in tax evasion cases-a rule bom in dictum and forged in repetition
