Olsson Funding Strategy Dashboard
No full textOlsson’s Funding Strategy Team works with communities to identify critical infrastructure projects in need of funding. The 2024-2025 Olsson Design Studio team developed the Funding Strategy Dashboard to deliver a streamlined process for identifying and assessing discretionary grant funding opportunities for city infrastructure projects. The dashboard leverages the Simpler.Grants.Gov API to quickly search, sort, and filter grant opportunities. Utilizing a custom-designed algorithm to determine similarity scores between funding opportunities and infrastructure projects, the main dashboard will allow the Funding Strategy Team to quickly assess the most applicable funding opportunities for a given project. The Funding Strategy Dashboard centralizes and filters large volumes of grant data and intelligently recommends the funding sources that are the best fit based on project characteristics and eligibility criteria
Effective Subscriber Identity Privacy Protections Within 5G Core Networks Through Ephemeral Identifiers
No full textInside a 5G Core Network, individual subscriber’s SUPIs (Subscriber Permanent Identi- fier) are utilized extensively throughout internal network calls, linking subscribers to their activities on the network. The use of linked identifiers can allow for tracking of subscriber location and behavior, creating significant challenges for protecting user identities and ensuring privacy. This becomes especially apparent in sensitive sectors such as military, government, and healthcare operations over public 5G networks. Relying on these personal identifiers threatens individual privacy rights, which highlights the urgent need for effective safeguards in both current and future cellular network technologies.
This thesis introduces an effective privacy protection scheme, replacing SUPIs with ephemeral IDs; specifically the SUEI (Subscriber Ephemeral Identifier) within Core Net- works. The application of the SUEI into existing 5G infrastructure requires an additional Virtual Network Function (VNF) — the IDPF (Identity Privacy Function) — is also intro- duced in this thesis. Tests of the IDPF are conducted using free5GC, an open-source 5G Core Network along with a simulated Radio Access Network (RAN) and User Equipment (UE) realized in the UERANSIM utility. Results from integration tests demonstrate that the effectively masks SUPIs within the Core Network using ephemeral IDs. While its integration fully adheres to the 5G protocol, it does necessitate a few targeted code migrations from the UDM and AMF to the IDPF in order to support specific key derivations aligned with the identifier stored in the UE. Packet captures which are presented show how the IDPF masks the SUPI in network calls. Further discussions are presented on the structural and trust changes, which are necessary within the Core Network to achieve this implementation.

No full textA toolkit developed to explore scenario-specific strategies and activities that research libraries can undertake to prepare for various possible AI-influenced futures. The toolkit integrates the ARL/CNI AI Scenarios published in spring 2024 along with priorities trialed and refined by strategic thinkers working directly in, or adjacent to, the research library field during a Strategic Implications forum held December 7–8, 2024, in Washington, DC
Pasture, Rangeland, Forage Insurance as a Risk Management Tool
No full textPasture and forage are the backbone of many Nebraska livestock operations, but they are also among the most vulnerable resources. Drought can quickly reduce forage production, leaving ranchers with tough choices of either buying expensive feed or cutting herd numbers.
One tool available to manage this risk is the USDA’s Pasture, Rangeland, and Forage (PRF) Insurance. Unlike traditional crop insurance, PRF doesn’t ensure the actual forage grown on your operation. Instead, it’s based on a rainfall index for your area. If rainfall falls below the long-term average during the months you select, you may receive an indemnity payment

No full textA History of Native People in Nebraska, Part I
No full textThe following isn’t a comprehensive history; the aim is to highlight important events and the ideas of those whose actions brought forth the history of the region and eventually the state of Nebraska. Using an analogy from the book The Nebraska State Constitution, we can think of how the state developed as a sort of fence, a way of separating what is “mine” and “yours”, who is “us” and “them,” and who the “insiders” and “outsiders” are.9 In examining the period leading up to the formation of Nebraska Territory, it is instructive to point to how outside forces desired and then claimed the land, though it was rightfully inhabited by several Indigenous nations, and how the relation of inside/ outside was quickly reversed as white settlers became established within the territory. Neither is this chapter a historical examination of each Nebraska tribe during this historical period. For a definitive treatment of this time period, I urge readers to consult David Wishart’s An Unspeakable Sadness: The Dispossession of the Nebraska Indians.10 Wishart comprehensively covers the histories of the Omaha, Otoe-Missouria, Pawnee, and Ponca Tribes, detailing all the treaties, the deaths resulting from the introduction of disease and alcohol, and the corrupt and unscrupulous Indian agents who were sent to “care for the Indians.
Exclusion from the Good Life: The Impact of Anti-Asian Racism on Asian Nebraskans
No full textTo understand how Americans of Asian descent experienced, adjusted, and overcame negative experiences in Nebraska, recognizing the external forces on their lives is paramount. The experiences of Asians in their diaspora across the U.S. and Nebraska during a 150-year span have been shaped by both external (global and domestic) and internal (personality and resilience) factors. The presence of stereotypes specifically targeted toward Asian Americans due to exotic imaginings, pseudoscience, and economic fears, in addition to the images created by national media, gave rise to society’s acceptance of stereotypes. These external factors contributed to a belief that continues to this day by non-Asians that Asian-looking people do not fit the image of who an American is. Government policies enacted over the past couple centuries seemed to cement the impression that careful diligence must be directed toward this group of people – based solely on their genetic inheritance and society’s preconceived notions. This chapter provides the background to realizing the impact of anti-Asian racism on Asian Nebraskans
Research Report: Confidence in Institutions
No full textThis report details 943 responses to the 2025 Nebraska Rural Poll, the 30th annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions about their confidence in institutions. Trends for some of the questions are examined by comparing data from the 2017 Poll and 2021 Poll to this year’s results. In addition, comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: Rural Nebraskans’ confidence in many institutions did not change much during the past eight years. However, more rural Nebraskans have a great deal of confidence in the presidency than they did in both 2017 and 2021. The proportion stating that they have a great deal of confidence in the presidency increased from 4 percent in 2021 to 17 percent this year. Conversely, fewer rural Nebraskans express a great deal of confidence in both the public safety agencies in their community and the public schools (K–12) in their community compared to four years ago. The proportion saying they have a great deal of confidence in the public safety agencies in their community decreased from 36 percent in 2021 to 25 percent this year. A similar trend occurred with the public schools in their community. The proportion having a great deal of confidence in the public schools in their community declined from 23 percent in both 2017 and 2021 to 17 percent this year. Overall, most rural Nebraskans have confidence in their local institutions (public safety agencies in their community, public schools in their community, and voting and election systems in their county). Most rural Nebraskans also have confidence in public libraries, community colleges, and public institutions of higher education. However, many express very little confidence in many national institutions (the Presidency, the U.S. House of Representatives, the U.S. Senate, and voting and election systems across the nation). Over one-half of rural Nebraskans have quite a lot or a great deal of confidence in public safety agencies in their community (68%), public libraries (68%), community colleges (62%), voting and election systems in their county (58%), public schools (K–12) in their community (56%), and public institutions of higher education (four-year colleges and universities) (51%). On the other hand, many rural Nebraskans have very little confidence in the following national institutions: U.S. House of Representatives (42%), U.S. Senate (42%), the Presidency and executive branch of government (38%), and voting and election systems across the nation (33%). Residents of the Panhandle are the regional group least likely to have confidence in the governor and state executive branch of government. Only 13 percent of Panhandle residents have quite a lot or a great deal of confidence in the governor and state executive branch of government, compared to at least one-quarter of residents of the other regions of the state. Conversely, over four in ten Panhandle residents have very little confidence in the governor and state executive branch of government. Older persons are more likely than younger persons to have confidence in the public safety agencies in their community. Almost eight in ten persons age 65 and older have quite a lot or a great deal of confidence in their public safety organizations, compared to one-half of persons age 19 to 29
An Economic Comparison of Crop Share vs. Cash Rent on a Southeast Nebraska Farm: A Case Study from Gage County (Dryland, Corn–Soybean Rotation, No-Till)
No full textIf you have recently inherited or purchased farmland in Nebraska, one of your first questions may be: How should I lease it? Two of the most common arrangements are cash rent and crop share. Each option comes with its own advantages and risks. More information on the difference between crop share and cash rental leases can be found here: UNL Extension — Considerations for Leasing: Cash Rent vs. Crop Share.
This article presents a case study of a dryland farm in Gage County, Nebraska, managed under a corn–soybean rotation with no-till practices. Entire fields may be planted to a single crop in one year and switched to the other crop the following year, or large fields may be divided between both crops and then alternated annually. Using 14 years of local data, we compare landowner returns under a 60/40 crop share lease versus typical-for-the-region, cash rent rates. Elements in the leases presented here are intended to highlight the essence of the lease. Leases are highly customizable to specific conditions faced by each landlord and tenant.
The results show how dramatically the choice of lease structure can affect average income over time and variations in yearly rental income. For the landlord, the decision boils down to a guaranteed rental payment, cash rent, or a variable rental share where income is based upon yearly yields and prices
