    State Immigration Policy and the Economy: Western United States

    Full text link
    States have been influenced by a variety of factors when creating local and state immigration laws. Although the enforcement of federal immigration law should not be enforced by state and local authorities, state legislatures have created their own laws in dealing with the immigrants that reside and work in their states. The research question of this paper is what economic factors influence states to introduce pro-immigrant policies? I will be looking at states in the west including Arizona, California, Colorado, Nevada, New Mexico, Oregon, Utah and Washington from the years 2016 to 2017. The specific factors observed in this paper are the labor union participation, unauthorized immigrants, DACA (Deferred Action for Childhood Arrivals) recipients, state revenue, and the employment increases. These factors are all linked to the economy of the state. I use inferential statistics through bivariate correlations, linear regression analysis, and logit regression analysis, to understand the significant correlations of these specific factors to whether states in the western United States implement pro-immigration policy

    Recently, construction costs have been at a global high – paired with increased global demand, rise in cost of material and limited skilled labor – it has become of utmost paramount to determine the solutions in the Civil Engineering industry to accommodate these changes and relieve these costs. Fastening to concrete has been important part of the construction industry for many years. Several standards have adopted a form of determining the strength of concrete breakout such as: ACI 318, ACI 349, or European code “Design of Fastenings in Concrete.” Many of these codes still reference testing and use equations that were developed in the early 1990’s. As technology in construction moves forward, so must the codes we use to design these new structures. Therefore, this study will evaluate whether the code is too conservative and can be expanded upon. Through the use of an FEA program, the effectiveness of shear anchor reinforcement is investigated. The load-bearing capacity is currently limited to three specific conditions: 1) No reinforcement present, 2) Edge reinforcement present, and 3) Edge reinforcement and stirrups spaced at 4in max. There are significant gaps in between these situations. Expanding condition 3) to include larger spacing would greatly benefit designers and laborers. Finite Element Analysis models will be run with 4 in, 6 in, and 8 in spacing between shear reinforcement stirrups. Peak loads will be extracted from each data and analyzed. Based on comparisons with the results, FE and calculations, recommendations are provided on the modification of existing code equations to expand to more conditions

    This research presents a mobile application framework designed to empower visually impaired individuals in Legazpi City by providing real-time audio feedback for currency identification. Leveraging deep learning techniques, the proposed framework employs a robust model trained on a comprehensive dataset of Philippine currency images. The deep learning model is capable of accurately classifying various denominations of bills and coins, enabling the development of an inclusive solution for the visually impaired community. The researcher employed a qualitative approach in this study, which included a focus group discussion. Respondents were chosen using purposive sampling. Among those who responded were masseuses, chiropractors, herbal street vendors, and students. Through an online meeting, the selected participants contributed to the focus group discussion. In addition, an in-depth informal interview was conducted to gather additional information for the development of an architectural framework. Based on the result of this study, it was discovered that by implementing this architectural framework, these groups would be able to more easily identify money, increasing efficiency and reducing errors in cash transactions. The use of audio labels is particularly helpful for visually impaired individuals, as it provides an accessible way for them to independently handle and identify money

    A Multiscale Observational Case Study of the Development of an Isolated High Plains Tornadic Supercell

    Get PDF
    On 21 May 1995, a strong tornado developed with an isolated supercell in southwestern Nebraska. Largescale conditions were not supportive of a tornadic thunderstorm outbreak; however, evidence suggests significant mesoscale enhancements produced a local environment favorable for strong tornado formation. This case study illustrates the importance of ‘‘situation awareness’’ and illustrates how mesoscale enhancements must be anticipated by forecasters in order to properly assess rapidly changing atmospheric conditions

    Implementation and Outcomes of an Education Focused Professional Development Series for Occupational Therapy Practitioners

    Get PDF
    As new educational programs emerge and student enrollment increases, the demand for new academicians, fieldwork educators, and capstone mentors is growing rapidly within the occupational therapy (OT) profession. Academic programs must prepare practitioners to teach and supervise their students who will become OTs and occupational therapy assistants (OTA). In conjunction with the state OT association, one university doctoral OT program created and implemented a free education-focused professional development series for community partners who were interested in developing their teaching knowledge and skills. The series covered unique aspects of OT and OTA education: fieldwork, the doctoral capstone experience and project, and how to become an academic educator. In total, 131 participants attended the three-part professional development series: 10% attended all three sessions, 12% attended two sessions, and 78% attended just one session. A post course evaluation found the majority of participants agreed they will apply the information learned into their practice, they valued the free professional development opportunities, and they were interested in attending future professional development opportunities. Participants had a high level of agreement that they achieved the specific learning objectives of the course. Not only did the community partners find the sessions to be beneficial, but the university OT program noted benefits to hosting it, with 83% of the participants reporting wanting to take a capstone student and 73% reporting a desire to become an academic educator. The purpose of this educational innovation article is to disseminate the content, objectives, and outcomes of the professional development series, in addition to sharing implications for OT and OTA educational programs

    The formation of small-scale atmospheric vortices via horizontal shearing instability

    Motivated by recent high-resolution observations of small-scale atmospheric vortices along near-surface boundaries, this study presents a series of simulations that attempt to replicate the dynamics of the dryline and surrounding boundary layer with special emphasis on misocyclones. The first simulation was a real data case, initialized and forced through time-dependent lateral boundary conditions via analyses of temperature, moisture, and momentum from the 22 May 2002 IHOP dataset. The second series of simulations were barotropic runs, initialized with a north-south oriented constant vorticity shear zone and north-south periodic boundary conditions. The third series of simulations were baroclinic, where the shear zone also contained and east-west temperature gradient. The barotropic and baroclinic simulations had varying magnitudes of shear and shear zone widths (corresponding to differing initial vorticity values) across the runs. Additionally, several barotropic simulations were rerun with moisture included to assess preferred could formation regions. The real data simulation produced several misocyclones with characteristics consistent with those observed along near-surface boundaries in the atmosphere. Several of these misocyclones also had features resembling those observed in many laboratory studies and other numerical studies. Many of these features were also found in the barotropic simulations (i.e. instabilities developed into elliptical cores that precess, contain pressure perturbations in their centers, and evolve with cores connected by vorticity braids). To assess the instability mechanism, the results were compared to linear theory. Excellent agreement was found between predictions from linear theory in terms of wavenumber of maximum growth as a function of shear zone width and growth rate as a function of shear zone vorticity, suggesting to a very good first approximation, horizontal shearing instability (HSI) is responsible for the growth of initial small perturbations. It was also found that predictions of linear theory tend to extend well into the nonlinear regime. The baroclinic simulations were more complicated and allowed for tilting and stretching of vorticity not seen in the barotropic simulations. As the shear zones contract due to frontogenesis, vorticity increases, thus increasing the growth rates and the wavenumber of maximum growth. An attempt was made to model the contraction and apply a “modified linear theory” to the results, by allowing linear theory to have a time-varying shear zone width. This modified model provided excellent agreement with the simulated results in terms of growth rate and wavenumber of maximum growth. Finally, an attempt was made to assess preferred regions of cumulus formation by including moisture in the real data case and in several barotropic simulations. It was found that maximum updrafts and simulated cumuli tend to form along the periphery of cores and/or along the braided regions adjacent to the cores. Due to the important modulating effect of misocyclone development via HSI and subsequent moisture transport, cumulus spacing and size/depth was also dependent on the shear zone width and vorticity

    The theory  of mental model  by Johnson-Laird will be used  as a framework for the development  of this qualitative study. The main purpose of the study was to examine college students’ individual and group mental models of Electrostatic Force and understand how these mental models evolved through instruction and group negotiation. Using a case study approach, this study utilized 6 case participants in a group of students enrolled in algebra based electromagnetism class. The primary data sources were video-taped interviews, focus group discussions, and in-depth analysis of concept maps, drawings, and other student-generated  outputs. Major finding of the study showed that majority of the constructed mental models of the students was anchored to the attraction – repulsion concept. Such mental model took center stage in understanding the concept of electrostatic force. The study also revealed that classroom instruction and group negotiation greatly impacted the development of college students’ mental models of Electrostatic Force. This study has made contribution to the knowledge of the evolution of mental models in understanding the concept of Electrostatic Force. &nbsp
