A Tribute To Frank Delno Holland, Jr. (1924-2023), Sigma Gamma Epsilon National President (1970-1975), Paleontologist, And Friend, John M. Erickson

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Frank Delno Holland, Jr., was born in Leavenworth, Kansas, on March 6, 1924. All family and friends, including his students and professional acquaintances, knew him as Bud. His parents were Frank D. Holland and Francys Bell Holland. His paternal grandparents, O.B. and Laura Holland were North Dakotans who had homesteaded in Sargent County during the 1880s, but had relocated to Kansas in 1903. Bud had a rural upbringing on the outskirts of Leavenworth, graduating in 1942 from Leavenworth High school. It seemed natural that he would follow in his father’s footsteps by attending the University of Kansas (KU) so Bud …

Beyond The Poster Session: Turning A Scientific Poster Into A Publishable Manuscript, Scott R. Beason Oct 2026

Beyond The Poster Session: Turning A Scientific Poster Into A Publishable Manuscript, Scott R. Beason

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Scientific posters are often treated as the final product of an undergraduate research project. After months of fieldwork, laboratory analysis, data processing, and interpretation, a student prepares a poster, presents the work at a departmental symposium or professional meeting, rolls up the poster, and moves on to the next stage of their career. The research, however, does not necessarily need to end with the poster session. A well-developed scientific poster already contains many of the fundamental elements of a scientific manuscript: a research question, scientific context, methods, results, figures, interpretation, discussion, and conclusions. Converting a poster into a manuscript therefore …

Old Rulings, New Reasons, Jack Boeglin Oct 2026

Old Rulings, New Reasons, Jack Boeglin

Michigan Law Review

When the Supreme Court does away with a longstanding legal principle, what should become of the hundreds, if not thousands, of precedents across the judicial system that rely upon it? Does some residual precedential value continue to attach to a decision even after its reasoning has been rejected? Or should it be overturned unless it can be upheld on a new, independently persuasive legal basis?

These are the questions courts must ask when deciding whether to “reharmonize” precedent. A court reharmonizes a past decision by supporting it on alternative grounds that better fit with changing legal or factual understandings.

The …


Two Cheers For Cox V. Sony, Christopher A. Cotropia, James Gibson Oct 2026

Two Cheers For Cox V. Sony, Christopher A. Cotropia, James Gibson

Northwestern Journal of Technology and Intellectual Property

Cox Communications, Inc. v. Sony Music Entertainment marks the first time in twenty years that the Supreme Court has addressed contributory infringement in copyright law. But rather than engage with the extensive appellate case law produced over those years, the Court instead chose to focus exclusively on the two forms of contributory infringement it had discussed in its own decisions: liability for intentionally providing a technology used for infringement by a third party, and liability for intentionally inducing the infringement of a third party. That’s it. The ruling contemplates no other form of contributory liability.

At first blush, then, the …

Climate Change Evidence: Driving Value-Added Use For Better Decisions, Tim Larson, Marina Lahowin, Sarah Hanck Oct 2026

Climate Change Evidence: Driving Value-Added Use For Better Decisions, Tim Larson, Marina Lahowin, Sarah Hanck

The Foundation Review

This article examines the evolving ecosystem of climate solution evidence tools and distinguishes the different functions they serve, including evidence aggregation, assessment of evidence strength, comparison of solution options, spatial targeting, policy benchmarking, and adaptive management.

Drawing from research on evidence-informed policymaking and climate decision science, the authors identify persistent barriers to evidence use, including misalignment with decision needs, deep uncertainty, institutional incentives, and limited capacity for collective sensemaking.

The article argues philanthropy’s greatest leverage lies not in increasing the supply of evidence alone, but in strengthening the systems through which evidence is interpreted, governed, and embedded in decision processes. …


Evidence And Learning Amid A Climate Crisis: Six Promising Frontiers For Advancing Practice, Tim Larson, Shawna Hoffman, Marina Lahowin Oct 2026

Evidence And Learning Amid A Climate Crisis: Six Promising Frontiers For Advancing Practice, Tim Larson, Shawna Hoffman, Marina Lahowin

The Foundation Review

The effects of the climate crisis are intensifying each year, just as the global context for mitigation, adaptation, and resilience efforts grows increasingly complex. Against a backdrop of urgency, resource scarcity, high uncertainty, and politicization, evidence is arguably more crucial than ever for informing climate action.

The potential of evidence for climate action has not been fully realized, leaving tremendous value on the table. This article argues that the challenge is not driven by a shortage of evidence, but rather by a mismatch between dominant evidence and learning practices and what decision-makers need.

In response to the question “how can …

From Rhetoric To Reality: Piloting Conversation-Based Reporting On Systems Change, Laura Rana Englert Oct 2026

From Rhetoric To Reality: Piloting Conversation-Based Reporting On Systems Change, Laura Rana Englert

The Foundation Review

The Climate Emergency Collaboration Group (CECG) is a philanthropic regranter aiming to unlock the power of international moments and systems to deliver a step-change in global response to the climate emergency. Both CECG’s work and the systems to which it contributes are characterised by complexity, non-linearity, and unpredictability.

CECG transformed its approach to reporting from traditional written reports using predetermined indicators to a conversation-based reporting (CBR) process prioritising depth over breadth and meaningful two-way exchange. CECG uses CBR to explore collective contributions to system change and drive evidence-informed decision-making.

This article provides a practice-based case study of CECG’s experience piloting …

Philanthropy And The Climate Crisis: Learning And Evaluation To Drive Decision-Making And Identify Emergent Opportunities, Lindsay Hanson, Rosy Kalfus, Courtney Lee Oct 2026

Philanthropy And The Climate Crisis: Learning And Evaluation To Drive Decision-Making And Identify Emergent Opportunities, Lindsay Hanson, Rosy Kalfus, Courtney Lee

The Foundation Review

To us, strategic learning is an adaptive approach to using evaluation and other data to directly affect decision-making and action.

An early focus on building relationships and accountability to specific outcomes and values — including establishing baselines and plans for regular reporting and interpretation — laid the groundwork for decision-making in later stages of the Climate Solutions program’s lifecycle.

Increasingly rapid data feedback loops informed the Climate Solutions program’s strategy pivot, decisions, and collaboration with grantees and funder partners.

Engagement in strategic learning and use of evaluation to drive decision-making improved with practice, as illustrated by the Climate Solutions team’s …


More Than The Sum: A Collective Vision For The Future Of Strategy, Monitoring, Impact, Learning And Evaluation (Smile) In Climate Philanthropy, Marta Arranz, Rees Warne, Olivia Deich, Amelia Abdelrazik Oct 2026

More Than The Sum: A Collective Vision For The Future Of Strategy, Monitoring, Impact, Learning And Evaluation (Smile) In Climate Philanthropy, Marta Arranz, Rees Warne, Olivia Deich, Amelia Abdelrazik

The Foundation Review

Organizations funding climate work must learn quickly and make urgent decisions despite uncertainties and low levels of control. Within climate philanthropy, sharing learnings widely and using evidence for decision-making are crucial.

The authors argue the “evaluation” field is both misdefined and underleveraged. In a shift away from accountability and siloed learning within organizations, they propose redefining the evaluation profession as SMILE (Strategy, Monitoring, Impact, Learning, and Evaluation).

After three years of building field-wide learning infrastructure, the authors reflect on the field’s progress and offer recommendations to the climate philanthropy ecosystem.


Climate Breakthrough's Impact And Learning System: A Case Study, Olivia Deich Oct 2026

Climate Breakthrough's Impact And Learning System: A Case Study, Olivia Deich

The Foundation Review

Climate Breakthrough makes one-time, multi-million-dollar, multi-year, flexible grants to climate strategists. The portfolio is collectively aimed at achieving an outsized emissions reduction goal. There are no strategy pillars, and grantees are from across the globe. This model, paired with Climate Breakthrough’s guiding values, opens the door for impact and learning work focused on iteration and learning.

In practice, grantees identify a small set of key performance indicators themselves; they share emissions reduction estimates for their work that are important but not dominant; they have abundant impact and learning resources; and the funder gains a wealth of data from which to …

Feedback Loops In Practice: A Case Study On Evaluating A Climate Collaborative, Mansi Shah, Amy Sherwood, Abbie Turiansky, Drew Koleros, Axum Teferra

The Foundation Review

Philanthropic support to address the climate crisis has grown substantially, yet it remains unclear how effectively philanthropies are learning from their investments, from each other, and from other actors about what generates meaningful impact. Evaluations have come under scrutiny, as conventional approaches often struggle to account for complexity and provide the timely insights needed for adaptive management.

In this article, the authors present the learning journey of a complex, systems-focused climate philanthropy initiative that uses structured feedback loops as an evaluation design. They describe how these loops were implemented over a two-year evaluation; discuss the choice of complexity-aware methods; and …


Spend-Down To Scale Up: Limited-Life Giving In The Climate Crisis, Madeleine C. Mckinnon, Samuel Rogers, David Gunsberg, Emma Mcintosh Oct 2026

Spend-Down To Scale Up: Limited-Life Giving In The Climate Crisis, Madeleine C. Mckinnon, Samuel Rogers, David Gunsberg, Emma Mcintosh

The Foundation Review

This article shares first-hand experiences of a charitable foundation operating under a spend-down model, illustrating how a fixed time horizon shapes philanthropic and programmatic behavior. The authors discuss three conditions that a spend-down horizon reliably forces: the imperative to fund quickly, collaboratively, and boldly on shared goals; the discipline to concentrate capital with strategic focus; and the emphasis on learning and collaboration as both a means to optimize for impact now and to sustain and scale impact over the long term.

Authors explore the influence of these conditions in a series of case studies working towards a clean energy transition …


Powerful Pulpits: Black Preachers As Cultish Leaders In The Axman Murders, 1909-1912, Lauren N. Henley Oct 2026

Powerful Pulpits: Black Preachers As Cultish Leaders In The Axman Murders, 1909-1912, Lauren N. Henley

Interdisciplinary Journal of Leadership Studies

Southwestern Louisiana and southeastern Texas experienced a series of disturbingly similar ax murders from November 1909 to August 1912. In nearly every case, a black family living within a mile of the Sunset Limited line of the Southern Pacific Railroad was brutally slaughtered in their own home, victims of a surreptitious assailant. Eventually, a young black woman would take credit for some of the crimes, ushering in the language of “religious fanaticism” as a potential motive. This confession sparked an intense period of criminalization of black male preachers, with a particular focus on Pentecostal leaders in southwestern Louisiana. This article …


Leader-Follower Formation-Based Leader Velocities Estimation Via Adaptive-Τ Tustin Differentiator, Zeyad A. Karam, Mohammed Y. Hassan, Amjad J. Humaidi Oct 2026

Leader-Follower Formation-Based Leader Velocities Estimation Via Adaptive-Τ Tustin Differentiator, Zeyad A. Karam, Mohammed Y. Hassan, Amjad J. Humaidi

Iraqi Journal of Computers, Communications, Control and Systems Engineering

This work develops a leader–follower formation for differential-drive mobile robots with an explicit estimator for the leader's velocities. Firstly, a leader robot position-variance-adaptive, under-rate-limited differentiator provides forward speed and yaw-rate estimate for the leader velocities, using exponentially weighted increment variances that drive a convex one-sided mapping to provide adaptive time constants for this estimator. Secondly, the control stack couples three layers: first layer, a nonlinear body-frame kinematic law for leader tracking, with orientation corrections handled via a smooth bounded function sin(eθ)/eθ to eliminate singularities near zero error. Second layer, a formation-preserving follower controller based on …

Power-Efficient Target Tracking And Coverage In Under-Provisioned Wireless Visual Sensor Networks, Muna M. Jawad

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Due to their ability to detect the physical environment, directional sensors have attracted a lot of attention in wireless visual sensor networks (WVSN). These sensors perform two key functions: communication and sensing. A WVSN comprises numerous configurable limited fields of view sensors, comprising distinct angular sectors, arranged with multiple targets randomly scattered in the same surrounding region. Therefore, there is a critical need to improve the network's lifetime and reduce power demand while providing complete target coverage. This paper looks at under-resourced visual networks with an inadequate number of sensors to match applications' needs and develops a viable model to …
