Preemption of Police Reform: A Roadblock to Racial Justice

In 2020, nearly half of the largest U.S. cities reoriented municipal spending priorities by directing money from their police budgets to social services; for many cities, these budgetary changes reversed decades of increases. Cities began implementing additional police reforms as well: New York City became the first municipality to end qualified immunity for police officers while San Francisco shifted to deploying crisis response teams, rather than police officers, to respond to mental health calls. Instead of supporting these critical reforms, some states targeted cities that prioritized racial justice by preempting those cities’ ability to engage in meaningful change. In the 2021 legislative session, ten states proposed at least twenty-four bills to preempt local governments from reducing their municipal law enforcement budgets, five of which ultimately passed. State leaders were transparent that their aim was to quash police reform and racial justice efforts: when signing House Bill 1 into law, Florida Governor Ron DeSantis stated “[t]his bill actually prevents against [sic] local government defunding law enforcement . . . . We’ll be able to stop it at the state level.” However, these preemption efforts have much broader implications than preventing police reforms: in Florida, as many cities face declining revenue this fiscal year, House Bill 1 allows for the takeover of a local budget if any reduction is made to law enforcement spending, including necessary cost-saving measures such as a voluntary early retirement program to freeze hiring across municipal departments. These new preemption measures bring the state into some of the most fundamental functions of municipal governance. This wave of police reform preemption is relatively new and still limited in scope but should be cause for great concern. These preemption bills are racially targeted, explicitly aiming to stymie collaboration between racial justice activists and local government. And further, these bills are not sound policy, as they directly interfere with local governments’ ability to respond to constituents and manage a municipal department. Rather, these bills are transparently partisan, placing conservative states’ culture wars above the welfare of communities. Now is the time to pay attention to this new trend in preemption. Only a handful of states have targeted municipal police reform, but if left unchecked, such preemption strategies will likely spread to other states. And without scrutiny, some states will feel emboldened to encroach further on the municipal ability to control and reform police departments

Evaluation of Program Satisfaction, Quality of Life, Strength, and Fall Risk of Community-Dwelling Older Adults Participating in a Community Exercise Program: Part 2

Background and Purpose: Bone Builders is an exercise program that incorporates both lower and upper extremities and is specifically designed for the older adult population. It was originally created for those that wanted to reduce their risk of osteoporosis, but currently there is no evidence that demonstrates these effects. However, exercises that are completed in the class are those that target causes of fall risk such as strengthening of hip abductors and balance activities. Participants have also reported that benefits of the class include improved balance, increased energy and mobility, and social support. Our study consisted of testing the fall risk of participants in this program, which were all women aged 65 years and older. This was compared to previous studies done, to determine whether this community exercise program decreases fall risk over time. Methods: Twenty-six participants, with ages ranging from 68-86 that are currently attending the Bone Builder\u27s program volunteered to participate in our study. Tests included were the 30 second sit-to-stand, grip strength, gait speed, TUG, and 4 stage balance tests. They also completed the Functional Efficacy Scale-International and a quality of life questionnaire, which measured subjective views of fall concern and overall satisfaction of attending the program. Results: The majority of participants were within the normative data ranges on all tests. Some assessments showed scores lower than the norms, particularly the 30 second sit-to-stand test. The majority of repeat subject\u27s scores improved or stayed the same, but some did worsen in the assessments, particularly for grip strength and gait speed. Overall, the age group ranging from 70-79 had the most scores above the normative data, and also scored higher on every assessment than the other age groups, except for the TUG. Conclusion: Bone builders has been shown to have a positive effect on participation in exercise, as well as improving the fall risk and safety of the participants. The program has a social aspect that allows for accountability among participants. On average, scores were above the normative data for each age group, which is indicative of a decreased fall risk and higher level of mobility

The economic contribution of third sector initiatives for older people: a systematic review and development of a framework for evaluation

An ageing population has placed strains on health and social care systems. Innovative solutions have been sought to inject capacity and capability in order to deliver services to older people more efficiently and effectively. Over the last two decades, governments have actively encouraged third sector organisations to deliver public services on the assumption that they exhibit higher levels of innovation, efficiency and responsiveness. The evidence base, particularly for whether they provide better value for money, remains poor. We present the results of a systematic literature review on the costs and outcomes of services for older people delivered by third sector organisations. We combine this evidence with a framework for analysing the benefits and costs of third sector-led initiatives, and test this out empirically with a group of initiatives delivered for older people in an urban context. We find that our method may hold considerable promise for the evaluation of third sector initiatives

AIAA Design, Build, Fly Team - MULLET Competition Aircraft 2021-2022

MULLET, the Medical Unmanned Low-Level Electric Transport, is Embry-Riddle Aeronautical University Daytona Beach’s aircraft for the 2021–2022 AIAA Design, Build, Fly competition. This UAV was designed to perform four missions, including a ground mission and three flight missions. Mission 1 is a deployment flight that demonstrates the aircraft’s flight capability; Mission 2 is a staging flight for the transportation of vaccine syringes; Mission 3 is a delivery flight for the transportation and deployment of vaccine vial packages; and the Ground Mission is a demonstration of the ability to rapidly prepare the aircraft for flight. The aircraft was designed, manufactured, and flown by a team of 40 undergraduate aerospace engineering students. The design process comprised three phases: conceptual, preliminary, and detail design. Initially, the conceptual design focused on analyzing the requirements with a scoring analysis to select the optimal payload that maximized the mission scores. After the aircraft and subsystem configurations were selected, the weight, wing, tail, and propulsion system were sized during the preliminary design. A detail design then focused on the aircraft’s structural characteristics and systems integration. The manufacturing process followed with the goal of fabricating the aircraft to the designed specifications and weight. A detailed schedule was developed and was continuously refined to manufacture each aircraft iteration in a timely manner, enabling rapid prototyping throughout the design, build, and fly process. Finally, a testing plan was established to evaluate a series of test objectives essential to the aircraft’s mission performance

TOI-1728b: The Habitable-zone Planet Finder confirms a warm super Neptune orbiting an M dwarf host

We confirm the planetary nature of TOI-1728b using a combination of ground-based photometry, near-infrared Doppler velocimetry and spectroscopy with the Habitable-zone Planet Finder.TOI-1728 is an old, inactive M0 star with \teff{} $= 3980^{+31}_{-32}$ K, which hosts a transiting super Neptune at an orbital period of $\sim$ 3.49 days. Joint fitting of the radial velocities and TESS and ground-based transits yields a planetary radius of $5.05_{-0.17}^{+0.16}$ R$_{\oplus}$, mass $26.78_{-5.13}^{+5.43}$ M$_{\oplus}$ and eccentricity $0.057_{-0.039}^{+0.054}$. We estimate the stellar properties, and perform a search for He 10830 \AA absorption during the transit of this planet and claim a null detection with an upper limit of 1.1$\%$ with 90\% confidence. A deeper level of He 10830 \AA ~ absorption has been detected in the planet atmosphere of GJ 3470b, a comparable gaseous planet. TOI-1728b is the largest super Neptune -- the intermediate subclass of planets between Neptune and the more massive gas-giant planets -- discovered around an M dwarf. With its relatively large mass and radius, TOI-1728 represents a valuable datapoint in the M-dwarf exoplanet mass-radius diagram, bridging the gap between the lighter Neptune-sized planets and the heavier Jovian planets known to orbit M-dwarfs. With a low bulk density of $1.14_{-0.24}^{+0.26}$ g/cm$^3$, and orbiting a bright host star (J $\sim 9.6$, V $\sim 12.4$), TOI-1728b is also a promising candidate for transmission spectroscopy both from the ground and from space, which can be used to constrain planet formation and evolutionary models.Comment: 21 pages, 12 figures, 4 tables: Accepted for publicatio

The Habitable Zone Planet Finder Reveals a High Mass and Low Obliquity for the Young Neptune K2-25b

Using radial velocity data from the Habitable Zone Planet Finder, we have measured the mass of the Neptune-sized planet K2-25b, as well as the obliquity of its M4.5 dwarf host star in the 600–800 Myr Hyades cluster. This is one of the youngest planetary systems for which both of these quantities have been measured and one of the very few M dwarfs with a measured obliquity. Based on a joint analysis of the radial velocity data, time-series photometry from the K2 mission, and new transit light curves obtained with diffuser-assisted photometry, the planet's radius and mass are 3.44 ± 0.12 R_⊕ and 24.5_(-5.2)^(+5.7) M_⊕. These properties are compatible with a rocky core enshrouded by a thin hydrogen–helium atmosphere (5% by mass). We measure an orbital eccentricity of e = 0.43 ± 0.05. The sky-projected stellar obliquity is λ = 3° ± 16°, compatible with spin–orbit alignment, in contrast to other "hot Neptunes" that have been studied around older stars

We confirm the planetary nature of TOI-1728b using a combination of ground-based photometry, near-infrared Doppler velocimetry and spectroscopy with the Habitable-zone Planet Finder. TOI-1728 is an old, inactive M0 star with T_(eff) = 3980⁺³¹₋₃₂ K, which hosts a transiting super-Neptune at an orbital period of ~3.49 days.

The Habitable-zone Planet Finder Reveals A High Mass and a Low Obliquity for the Young Neptune K2-25b

Using radial-velocity data from the Habitable-zone Planet Finder, we have measured the mass of the Neptune-sized planet K2-25b, as well as the obliquity of its M4.5-dwarf host star in the 600-800MYr Hyades cluster. This is one of the youngest planetary systems for which both of these quantities have been measured, and one of the very few M dwarfs with a measured obliquity. Based on a joint analysis of the radial velocity data, time-series photometry from the K2 mission, and new transit light curves obtained with diffuser-assisted photometry, the planet's radius and mass are $3.44\pm 0.12 \mathrm{R_\oplus}$ and $24.5_{-5.2}^{+5.7} \mathrm{M_\oplus}$. These properties are compatible with a rocky core enshrouded by a thin hydrogen-helium atmosphere (5% by mass). We measure an orbital eccentricity of $e=0.43 \pm 0.05$. The sky-projected stellar obliquity is $\lambda=3 \pm 16^{\circ}$, compatible with spin-orbit alignment, in contrast to other "hot Neptunes" that have been studied around older stars.Comment: Accepted for publication in AJ, 31 pages, 14 figure
