A Reconceptualization Of Servant-Leadership And Measurement, Lori Doyle, Larry H. Ludlow

International Journal of Servant-Leadership

Servant-Leadership (SL) has been gaining traction as an evidence-based leadership theory and there are a range of existing measurement tools focused on self-report attitudes, beliefs, opinions, and behaviors. Concordia University Irvine has embedded a SL framework throughout all programs of study offered by the School of Education in order to encourage current and future education professionals in their understanding of servant-leadership as an effective way to lead. It was determined that a published instrument did not exist for measuring knowledge growth as a pre- and post-test focused on increased understanding. Work to define SL in terms of four specific virtues …

International Journal of Servant-Leadership

Servant-leadership is an emerging area of study in leadership research that emphasises a people-oriented leader-follower relationship and a humanistic approach to leadership behaviour. Due to the limited research on servant-leadership, this study adopts an exploratory approach to examine the applicability of Cheung’s servant-leadership model in Hong Kong schools. Our research investigates both the practical implementation of this model and the challenges encountered in translating theory into practice. We conducted semi-structured interviews with twelve experienced school leaders who had participated in a long-running servant-leadership training programme. The interview transcripts were analysed to assess the twelve servant-leadership qualities outlined in the model. …

Can Better Transportation Infrastructure Help Bridge The Gender Mobility Gap?: Analysis Of The Dhaka Metro Rail, Prottoy A. Akbar, Tomoki Fujii, Arpita Khanna, Abu S. Shonchoy

Research Collection School Of Economics

Inadequate transportation infrastructure is a pressing challenge in rapidly expanding urban centers globally. However, the differential impacts of infrastructure improvements for women versus men remain inadequately understood and underexplored. This study addresses this knowledge gap by documenting gender-specific travel patterns and perceptions of safety in Dhaka, Bangladesh. Specifically, we analyze how the introduction of Dhaka’s first mass rapid transit (MRT) line has altered modes of transportation, the frequency of travel, and safetyrelated concerns among women. Our empirical findings highlight that the new MRT line has notably influenced women’s travel behaviors, particularly by alleviating safety concerns that previously discouraged regular travel.

Veldman, Forrest Fleischman, Pooja Choksi, Sally Archibald, Mohammed Armani, Matthew E. Fagan, Evan C. Fricke, César Terrer, Natalia Hasler, Christopher A. Williams, Peter W. Ellis, Susan Cook-Patton

Geography

Reforestation is a prominent climate change mitigation strategy, but available global maps of reforestation potential are widely criticized and highly variable, which limits their ability to provide robust estimates of both the locations and total area of opportunity. Here we develop global maps that address common critiques, build on a review of 89 reforestation maps created at multiple scales, and present eight reforestation scenarios with varying objectives, including providing ecosystem services, minimizing social conflicts, and delivering government policies. Across scenarios, we find up to 195 Mha (million hectares) are available (2225 TgCO2e (teragrams of carbon dioxide equivalent) per year total …

Exploratory Innovation: A New Perspective On Family Firms' Under-Diversification Puzzle, Po-Hsuan Hsu, Sterling Huang, Massimo Massa, Yaru Qian, Hong Zhang

Research Collection Lee Kong Chian School Of Business

We propose a new perspective on family firms’ puzzling under-diversification in product spaces: these firms first need to succeed in exploratory innovation so they may diversify into new product markets. We construct a large database of family ownership and patent records of U.S. public firms, and show that family firms produce more exploratory patents than others, a relation that is stronger among under-diversified family firms. In addition, we find that such innovation indeed helps family firms diversify business risks. A causal interpretation of our result is supported by (i) using the property division standard in state-level divorce laws as an …

The Nature Of Scientific Justification, Haixin Dang

Faculty Scholarship

Mikkel Gerken’s book Scientific Testimony is a welcome step in reconnecting contemporary analytic epistemology with the philosophy of science. The central topic of the book—as it says in the title—is testimony, which has been a major area of research for epistemologists for the last couple of decades. Testimony refers to the process by which we can acquire knowledge or justified belief from what others have told us. Roughly speaking, epistemologists agree that testimony is an important source of knowledge but disagree over the exact conditions under which testimony can lead to knowledge. But for philosophers of science, learning from one …

The individual later received a wirelessly connected implanted …

Real Topological Hochschild Homology Via The Norm And Real Witt Vectors, Gabriel Angelini-Knoll

Faculty Scholarship

We prove that Real topological Hochschild homology can be characterized as the norm from the cyclic group of order 2 to the orthogonal group O(2). From this perspective, we then prove a multiplicative double coset formula for the restriction of this norm to dihedral groups of order 2m. This informs our new definition of Real Hochschild homology of rings with anti-involution, which we show is the algebraic analogue of Real topological Hochschild homology. Using extra structure on Real Hochschild homology, we define a new theory of p-typical Witt vectors of rings with anti-involution. We end with an explicit computation of …

Enhanced Dielectric Insulation Of Biaxially Oriented High Temperature Polyester Films For Capacitive Energy Storage, Tianke Chen, Michael Chen, Jiazhen Liu, Eric Baer, Lei Zhu

Faculty Scholarship

Biaxially oriented polypropylene (BOPP) films are widely used in dielectric capacitors due to their ultralow loss, high breakdown strength, and long lifetime. However, their poor temperature tolerance limits applications in emerging high-temperature environments such as wide-band-gap power electronics in electric vehicles. Here, we report significantly enhanced dielectric insulation properties of biaxially oriented poly(ethylene 2,6-naphthalate) (BOPEN) films compared to biaxially oriented poly(ethylene terephthalate) (BOPET) films, despite their similar semicrystalline morphologies. BOPEN exhibits higher DC and AC breakdown strengths and markedly extended lifetimes at elevated temperatures. For instance, at 120 °C, the DC Weibull lifetime of BOPEN exceeded that of BOPET by …

Framerate Sensitivity And Cinemagoing Explain The Soap Opera Effect Of Films: A Preregistered Study Of Undergraduate Students In Singapore., Sonny Rosenthal, Benjamin J. Li

Research Collection College of Integrative Studies

The soap opera effect is an unsettling feeling that some individuals experience while watching films at a high framerate. It has received little scholarly attention, and most explanations of it are speculative or anecdotal. Drawing on the mere exposure effect, this preregistered laboratory experiment provides new evidence of framerate sensitivity and cinemagoing as explanatory factors of the soap opera effect. Undergraduate students (N = 270) reported their cinemagoing and completed a novel task to measure their framerate sensitivity. They also completed a task indicating their framerate preferences. Those with a higher framerate sensitivity and more regular cinemagoing preferred the standard …
