An Intelligent and Data-Driven Mobile Platform for Youth Volunteer Management using Machine Learning and Data Analytics

In Lewis and Clark High School’s Key Club, meetings are always held in a crowded classroom. The system of eventsign up is inefficient and hinders members from joining events. This has led to students becoming discouraged fromjoining Key Club and often resulted in a lack of volunteers for important events. The club needed a more efficientway of connecting volunteers with volunteering opportunities. To solve this problem, we developed a Volunteer Match Mobile application using Dart and Flutter framework for Key Club to use. The next steps will be toadd a volunteer event recommendation and matching feature, utilizing the results from the research on machine learning models and algorithms in this paper.

Liquor and the Ethnic Cleansing of North America

Chapter 10 continues the focus on Native American temperance by highlighting the tension between US government goodwill and fair trade with native tribes on the one hand, and predatory capitalists—including John Jacob Astor’s American Fur Company—who used liquor to subjugate the tribes on the other. William Clark (of Lewis and Clark fame) became an important mediator in this conflict between native pleas for prohibition and white profits. The role of distancing from predatory white liquor traders gives new perspectives on the Trail of Tears in the South, while the role of disputes over illegal white liquor peddling initiated the Black Hawk War to the North. As native tribes both north and south were relocated to the unsettled lands west of the Missouri and Arkansas territories, they found unscrupulous liquor dealers—including American Fur—waiting to take their tribal annuities in exchange for addictive liquor.

Construction of the Lewis and Clark cable-stayed bridge over the Ohio River

<p>Constructed under a $780 million public private partnership contract (P3), the Lewis and Clark Bridge crosses the Ohio River at approximately 13Km northeast of downtown Louisville, Kentucky, and features a 695.1 m long three-span symmetrical steel composite cable-stayed bridge with a center span of 365.9 m. To meet an aggressive schedule required by the Concessionaire towards earlier collection of toll revenues, the construction of the bridge was accelerated by nearly one year through early staging of the superstructure steel grillage in both the back spans while completing construction of the towers. The steel grillage for the Kentucky backspan was stick-built, while for the Indiana backspan it was incrementally launched into position in a unique such application in a cable-stayed bridge project in the US. Following the simultaneous completion of the two backspans and the towers, the center span construction proceeded in balanced cantilever constructing the two tower cantilevers simultaneously. 104 stay-cables were erected and the center span steel grillage and the 695m long cable-stayed deck (over 800 precast panels) constructed in record time of only five months. The paper provides an overview of bridge structural system and characteristic structural details, and discusses the methods of construction for the substructure, towers, and the superstructure of the cable-stayed bridge.</p>

The representation of the American territory and the controversy between Jefferson and Buffon

The Franco-American confrontation of scientific reports on nature reveals that the Lewis and Clark Expedition was not so essentially a conquering move as previously asserted because it was conceived mostly within the context of a scientific survey with the aim to prove or disprove Buffon’s contention that the American climate was that of paradise (hot and humid), and that the absence of hardship fostered mediocrity if not degeneration. In his admiration for Buffon, Thomas Jefferson strove to bring his observations to the attention of the French naturalist, beginning with his own publication on Virginia botanical surroundings, and with his observations on large American animals that included the Mammoth, whom he thought still alive because of his respect for creationism. The fact that large animals were roaming the continent disproved that degeneration was the fate of its inhabitants, degeneration implying a diminutive size. As well, “Indians” were not any lesser than other human beings (since creationism excluded evolution one way or the other, and he saw no evidence of degeneracy in any kinds of beings from America). He did foresee that they might benefit from their adoption of British forms of governance and religion so that perhaps, in due time, they could establish their own “nations”.

Factors related to age-0 native fish catch per unit effort in the South Dakota Missouri River reservoirs.

The Missouri River in South Dakota was dammed in the 1950s and 1960s, altering the biotic and abiotic factors that potentially affect native species in the mainstem reservoirs. Little research has been conducted regarding what factors regulate age-0 CPUE (catch per unit effort) of native fish species since the damming occurred. Thus, we examined age-0 CPUE for thirteen native fish species in the four Missouri River mainstem reservoirs. We analyzed data from 1995-2015 in Lake Oahe, 2002-2016 in Lake Sharpe, 1998-2008 in Lake Francis Case, and 2000-2013 in Lewis and Clark Lake. Not all species were sampled in all reservoirs. We evaluated potential environmental (inflow, gauge height, peak flow, precipitation, air temperature) and biological (CPUE of other native species, non-native CPUE, predator CPUE) factors that have documented impacts on age-0 native fish CPUE. Significant relationships existed between age-0 native fish CPUE and both biotic and abiotic factors in all four reservoirs, but specific factors related to native fish CPUE were species and reservoir dependent. For all species examined in all reservoirs except age-0 Emerald Shiner Notropis atherinoides CPUE in Lewis and Clark Lake, age-0 CPUE was either stable or increasing. Age-0 Emerald Shiner CPUE in Lewis and Clark Lake was most supported by total age-0 non-native CPUE and adult White Bass Morone chrysops CPUE, and a positive relationship existed between age-0 Emerald Shiner CPUE and both factors. We believe our findings provide valuable insight into successful management of native fish populations.

Now They Will Pretend to Equal Us

This chapter describes Blackfoot responses to increasing colonial activity on the northwest plains and Rocky Mountains between 1806 and 1821. Ascending the Missouri River to their south, the American expedition of Lewis and Clark circumvented the Blackfoot to open ties with Native nations in the intermountain West. British explorer David Thompson did the same in the north, accessing the mountains near the headwaters of the North Saskatchewan River. Blackfoot people responded to these invasions with a targeted campaign of diplomacy and conflict, including blockades of key mountain passes, that severely limited American, Canadian, and British ambitions in the region for a generation. These conflicts also led to an overly simplistic depiction of Blackfoot “hostility” that lingers to this day.
