Mapping For Impact: Actionable Spatial Literacy Through Counter-Mapping, Rachel Hansen

Dissertations and Theses @ UNI

Counter-mapping is a technique that young people can use to take informed action on community issues through the mapping process. This mixed-methods study examined how ninth-graders in a large urban district in Iowa developed spatial thinking skills while engaging in counter-mapping in their community and the extent to which they used those maps to take informed action. A nine-week learning progression for counter-mapping scaffolded progress variables across three different spatial thinking standards and one inquiry standard. Findings indicated that students improved throughout the learning progression, but some needed teacher support to conduct spatial inquiries. Chances of reaching the upper anchor …

“I Can’T Do This Anymore, But I Have 1000 More Kids To Serve”: A Qualitative Study Of Full-Time Residential Summer Camp Staff Burnout, Sarah Cohen

Dissertations and Theses @ UNI

Early pioneers of burnout defined it as “to fail, wear out, or become exhausted by making excessive demands on energy, strength, or resources'' (Freudenberger, 1974, p. 159; Freudenberger, 1977; Schaufeli & Enzmann, 1998). The traditional structures and activities of summer camps play a large role in creating experiences for staff and campers alike, but can lead to full-time staff working long hours with little time off and a culture of being overworked as a symbol of dedication to the program. While burnout research has become more popular over the past few decades, little is known about how burnout is experienced …

No Need To Set The Alarm, I’Ve Been Up Since 2:30am! Why My Teaching Job Keeps Me Up At Night: A Phenomenological Research Study On Empathic Strain Of Iowa Educators, Lindsey Cornwell

Dissertations and Theses @ UNI

Empathic strain describes a stressor on individuals in professions in which one cares for others who have endured their own trauma or stress (Mathieu, 2021). While previous studies have looked mainly at medical, social work and law enforcement fields as being some of the most impacted by empathic strain, more recently educators have been identified as those challenged with this phenomenon.

Through a phenomenological qualitative study, which included a Facebook marketed Qualtrics survey on empathic strain, four individual interviews and a metaphorical data analysis focus group experience, the lived experiences of educators with empathic strain were collected. Each of the …

Observer-Based Model Predictive Control With Continuous Control Set For Single-Phase Rectifiers, Milad Dehghanzadeh, Rui Bo, Kamal Al-Haddad

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a model predictive controller (MPC) is designed for a single-phase rectifier. The proposed MPC works with a continuous control set (CCS) that addresses variable switching issues in finite control set (FCS) MPCs. The observe-ability of the rectifier enables the design of a full-state observer to measure only output voltage in which the AC current of the rectifier is estimated. Both the proposed controller and observer are assessed with simulation studies and the results show the acceptable performance of the observer and CCS-MPC as well as good disturbance rejection in load and network parameter variations.

Delivering Broadband Light Deep Into Diffusive Media, Rohin Mcintosh, Nicholas Bender, Alexey Yamilov, Arthur Goetschy, Chia Wei Hsu, Hasan Yilmaz, Hui Cao

Physics Faculty Research & Creative Works

Waves propagate diffusively through disordered media, such as biological tissue, clouds, and paint, due to random scattering. Recent advances in optical wavefront shaping techniques have enabled controlling coherent light propagation in multiple-scattering samples. We overcome wave diffusion to deliver optical energy into a target region of arbitrary size and shape anywhere inside a strong-scattering system. This is particularly important for applications such as photoacoustic microscopy and optogenetics, where light needs to be deposited deep into biological tissue. For monochromatic light, we previously introduced the deposition matrix (DM) Z(ω), which maps its input wavefront to the field distribution in the target …

Nanomaterial Payload Delivery To Central Nervous System Glia For Neural Protection And Repair, Jayant Saksena, Adelle E. Hamilton, Ryan J. Gilbert, Jonathan M. Zuidema

Chemical and Biochemical Engineering Faculty Research & Creative Works

Central nervous system (CNS) glia, including astrocytes, microglia, and oligodendrocytes, play prominent roles in traumatic injury and degenerative disorders. Due to their importance, active pharmaceutical ingredients (APIs) are being developed to modulate CNS glia in order to improve outcomes in traumatic injury and disease. While many of these APIs show promise in vitro, the majority of APIs that are systemically delivered show little penetration through the blood–brain barrier (BBB) or blood-spinal cord barrier (BSCB) and into the CNS, rendering them ineffective. Novel nanomaterials are being developed to deliver APIs into the CNS to modulate glial responses and improve outcomes in …

This article proposes a unified threat landscape for participatory crowd sensing (P-CS) systems. Specifically, it focuses on attacks from organized malicious actors that may use the knowledge of P-CS platform's operations and exploit algorithmic weaknesses in AI-based methods of event trust, user reputation, decision-making, or recommendation models deployed to preserve information integrity in P-CS. We emphasize on intent driven malicious behaviors by advanced adversaries and how attacks are crafted to achieve those attack impacts. Three directions of the threat model are introduced, such as attack goals, types, and strategies. We expand on how various strategies are linked with different attack …

Preserving Privacy In Image Database Through Bit-Planes Obfuscation, Vishesh K. Tanwar, Ashish Gupta, Sanjay Kumar Madria, Sajal K. Das

Computer Science Faculty Research & Creative Works

The recent surge in computer vision applications has caused visual privacy concerns to people who are either users or exposed to an underlying surveillance system. To preserve their privacy, image obfuscation lays out a strong road through which the usability of images can also be maintained without revealing any visual private information. However, prior solutions are susceptible to reconstruction attacks or produce non-trainable images even by leveraging the obfuscation ways. This paper proposes a novel bit-planes-based image obfuscation scheme, called Bimof, to protect the visual privacy of the user in the images that are input into a recognition-based system. By …

Lasa: Location-Aware Scheduling Algorithm In Industrial Iot Networks With Mobile Nodes, Marco Pettorali, Francesca Righetti, Carlo Vallati, Sajal K. Das, Giuseppe Anastasi

Computer Science Faculty Research & Creative Works

The Synchronized Single-hop Multiple Gateway (SHMG) is a framework recently proposed to support mobility into 6TiSCH, the standard network architecture defined for Industrial Internet of Things (IIoT) deployments. SHMG supports industrial applications with stringent requirements by adopting the Shared-Downstream Dedicated-Upstream (SD-DU) scheduling policy, which allocates to Mobile Nodes (MNs) a set of dedicated transmission opportunities for uplink data. Such allocation is performed on all the Border Routers (BRs) of the network without considering the location of MNs. Transmission opportunities are reserved also in BRs far from the current location of the MN, resulting in a waste of resources that limits …

After ionic crosslinking, the 3D-printed dressings were characterized for mechanical properties, degradation rate, hydration …

Judging Better Together: Understanding The Psychology Of Group Decision-Making On Panel Courts And Tribunals, Brian M. Barry Dr

Articles

While the psychological phenomena that affect group decisionmaking have been thoroughly investigated for decades, how these phenomena apply to decision-making by judges on panel courts is under-examined. This article examines the main psychological phenomena of group decision-making, both positive and negative, and considers their implications for panel courts and other groups of professional legal decision-makers such as adjudicators serving on tribunals. This article argues that experimental studies on judges and adjudicators testing the effects of these phenomena would improve understanding of legal decision-making by these groups and could help to devise ways to improve their decision-making processes to reach higher …

Gender Inequality In Contracts Casebooks: Representations Of Women In The Contracts Curriculum, Deborah Zalesne

FIU Law Review

Gender has always explicitly or implicitly played a critical role in contracting and in contracts opinions—from the early nineteenth century, when married women lacked the legal capacity altogether to contract, through the next century, when women gained the right to contract but continued to lack bargaining power and to be disadvantaged in the bargaining process in many cases, to today, when women are present in greater numbers in business and commerce, but face continued, yet less overt, obstacles. Typical casebooks provide ample offerings for discussions of the ways in which parties can be and have been disadvantaged because of their …

"Covid-19 Was The Publicist For Homeschooling" And States Need To Finally Take Homeschooling Regulations Seriously Post-Pandemic, Kristia Hoffman

FIU Law Review

Homeschooling was rapidly growing in the U.S. even before COVID-19. The pandemic accelerated this growth by quickly exposing nearly every American family to homeschooling in some form. The pandemic has ushered in a new age of homeschooling characterized by flexibility, technology, collaboration, and alternative forms of schooling beyond the traditional parent-teaching-child framework. Although the Supreme Court has never recognized a fundamental right of parents to homeschool their children, it has repeatedly recognized that parents have the right to direct their children’s education and to choose to educate them in the way they deem fit. There is debate as to what …
