Psychological Ownership and Insecure Adult Attachment
Full text linkPsychological ownership (PO) pertains to individual feelings of being psychologically tied to and possessive of an object or a target. PO has been studied as a factor related to workplace outcomes-for example, a sense of PO in one\u27s organization is associated with work performance and job satisfaction. The motives for PO come from human fundamental needs: efficacy, self-identity, and belongingness. Other dimensions include accountability and territoriality. The study investigates the relationship between PO and insecure adult attachment dimensions: avoidance and anxiety. Avoidantly attached individuals tend to be self-reliant and autonomous, use work as a distraction, and are thus hypothesized to have more PO. Anxiously attached adults tend to have lower self-esteem than non-anxious individuals, prefer to work with others, have interpersonal concerns interfering with productivity, and are thus hypothesized to have lower levels of PO. Analyses were conducted on 288 full-time employees. Results revealed that anxiously attached individuals tend to have higher levels of overall PO. Both anxious and avoidant attachment positively relate to the territoriality subscale of PO. Anxious attachment is positively associated with the self-efficacy subscale whereas avoidant attachment is negatively associated. Avoidant attachment is negatively correlated with accountability and belongingness subscales. Ultimately, this study provides more information about the personality traits associated with PO, which is in turn associated with work performance and job satisfaction. The results can be used to implement interventions to improve the dynamic of the workplace
Non-Invasive, Acute Treatment of Supraventricular Tachycardia for Pediatric Patients
No full textSupraventricular tachycardia (SVT) is a heart condition in which an individual experiences unexpected episodes of an irregular resting heart rate, up to 200 bpm. SVT affects people of all ages, but is the most common heart arrhythmia diagnosed in the pediatric population. Currently, there are no non-invasive devices designed for the acute treatment of SVT, resulting in an increased amount of hospital staff to implement invasive treatments. These invasive methods have adverse effects that include temporarily stopping the patient\u27s heart in hopes it will return to a normal rhythm. Therefore, we developed a pediatrics-oriented, non-invasive device to slow down the patients\u27 heart rate and prevent a traumatic experience for the patient, decrease the hospital staff required, and decrease patient risk
Constant Velocity Joints for the 2023 Union College Baja Racing Team Car
No full textConstant velocity (CV) joints have a long history of development. They are designed to transmit angular velocity from one axle shaft to another when they are not collinear. The Union College Baja racing team decided to use CV joint axles as outboard drive shafts (half shafts), which deliver the power from the engine to the wheels, in the 2023 car. Due to the geometries of the joints\u27 components, they are difficult to manufacture without specialized equipment. Therefore an axle assembly was ordered. However, it was very difficult to find a CV axle to purchase and without a car it is near impossible to test. Dynamic analysis is a useful tool which could be used to study potential selections and whether they would fail
Dame sexo o vete: Cómo la adición de mujeres crean una narración heteronormativa y sexista en Fresa y Chocolate
No full textThis work examines the differences between the short story El lobo, el bosque y el hombre nuevo by Senel Paz (1990) and its film adaptation Fresa y Chocolate de Tomás Gutiérrez Alea y Juan Carlos Tabío Cuba (1993), with a focus on the expansion on and inclusion of two female characters. It argues that these differences build and promote a heterosexual narrative that was not intended in the original story. The context regarding the LBGTQ community, specifically the discrimination they faced during the Communist Revolution in Cuba, is given as a precursor to the subsequent analysis of the works. The focus then shifts to the comparison of these works, primarily regarding the expansion of the character Vivían and the creation of the character Nancy in the film adaptation. The inclusion of these women in the film pushed a heterosexual narrative by defining the sexuality of the main character, David. Both women are utilized as pawns, included only to advance the storyline of the men, and presented only as objects to define and appeal to male sexuality. This presents a heteronormative, sexist view that the original work did not seek to promote and actively worked against. This heteronormative narrative silences the voices of the LGBTQ community by depriving them of representation. This new film narrative promotes problematized views and beliefs surrounding these marginalized communities
Wage Dispersion and Individual Performance: MLB Pitchers
Full text linkMajor League Baseball is one of the most valuable sports leagues valued at 7 million US dollars. The disparity between the max starting pitchers and the minimum relief pitchers is $20.5 million US dollars. Previous studies find that there is much evidence to support that as wage dispersion among a team increases, the overall team performance is negatively affected. In addition, there are some studies which find no correlation, or positive correlation between salary inequality and efficiency. Jewell and Molina (2004) find that salary inequality does not appear to be correlated with efficiency in the MLB. This paper analyzes how wage dispersion and salary inequality affect individual performance among pitchers in Major League Baseball (MLB). To answer this question, we examine the relationship between wage dispersion and individual performance of the rostered pitcher on all 30 MLB teams across 10 seasons using seasonal statistics which include team and player specific metrics. The economic goals of the study is to further the research surrounding two competing salary theories: tournament theory and cohesion theory. The results of this study show that with larger wage dispersions or pay inequality across teams and the pitching specific positional payroll, there is statistically significant negative impact on individual performance
Association Between Previous Mental Health Disorders and Post- COVID-19 Conditions
Full text linkThe COVID-19 pandemic has proven to be challenging to many scientists and physicians due to its rapid spread and long lasting effects. The objective of this study is to determine whether high levels of psychological distress leads to increased risk of developing post-COVID-19 conditions (long COVID). A total of 55 participants from a small family practice in New York State were the sample for this study. Patient charts were reviewed to gather PHQ-9 scores and look for diagnoses of long COVID symptoms. The results did not reveal any significant relationship between mental health conditions and long COVID symptomatology
Prediction of Future Workload in Cloud Datacenter
No full textCloud computing provides various types of computing utilities where clients pay for services depending on their requirements and consumption. The resources used by machines in a cloud datacenter oscillate over time, which can affect application performance. As the number of users for cloud computing has increased significantly, load balancing has become a crucial factor cloud service providers need to consider. Load balancing is a technique for dynamically shifting tasks between machines in order to reduce the workload of machines whose capacities are reached and increase the workload of machines that are idle. Load balancing can be improved when used with accurate predictions of future resource usage. Such predictions help identify potentially overloaded machines before it occurs. I present a Machine Learning-based approach to evaluate how accurately we can predict the future workload of these machines, using Google Cluster Trace 2011. The results show that a simple Machine Learning model like Linear Regression can improve the accuracy of workload prediction for the next 5 minutes by 7.5%, the next 10 minutes by 6%, and the next 15 minutes by 3.5% over that of a baseline method
The effect of weight gain on the neuromechanics of locust jumps (Schistocerca americana)
Full text linkDuring the adult reproductive stage, female locusts (Schistocerca americana) experience multiple ovigerous cycles during which they undergo significant weight gain. The magnitude of their weight change is thought to negatively impact the kinematics of the locust jump during the gravid phase. We hypothesized that this decrease in performance would result in an evolutionary pressure for female locusts to develop an intrinsic means to detect increases in body mass and respond with a modulation in their movement. Based on this hypothesis, we predicted that the female locusts would display a consistent jump performance in response to weight change, facilitated by a change in the contraction time of their extensor tibiae muscles. Conversely, this type of control is not expected in male locusts since they do not experience the same cycles of weight. These predictions were tested using an artificial weight gain system to induce weight gains similar to natural changes. Simultaneous high-speed video capture (1500 frames per second) and bilateral electromyogram (EMG) recordings were obtained from nine female and five male locusts during evoked escape jumps. Multiple jumps were recorded for each individual, corresponding to different artificial weight gain conditions. The peak angular velocity of the jumping legs was calculated using position tracking software (DeepLabCut) and subsequent kinematic analysis of the leg rotation using custom scripts in R. Contraction time was calculated from the extensor tibiae muscle EMG recordings. Female and male locusts maintained consistent peak angular velocity during extensions of their jumping legs in response to weight gain, indicating that both sexes modulate jump performance for different body masses. Furthermore, both sexes displayed increased contraction times for small weight increases, but contraction times for large weight increases were comparable to those of their natural body mass
Evolving Difficulty Targeted Bouldering Routes
Full text linkThe challenge of utilizing artificial intelligence to generate indoor rock climbing routes with a specific grade is an interesting and unsolved problem due to its complexity and subjectivity. We use MAP-Elites, an evolutionary, quality-diversity algorithm, in conjunction with GradeNet [8] to produce a set of disjoint MoonBoard climbing routes that sufficiently challenge a climber without exceeding their physical and technical limitations. We evaluate these routes through visual a assessment survey by climbers as well as an in-person study in which climbers attempt to climb the generated routes. While our algorithm generally performs well in producing complete or near-complete archives of diverse climbs at every difficulty level as assessed by GradeNet, they fall short when it comes to in person trials. Additionally, the data from user surveys, while supporting the claims of Duh and Chang [8] about GradeNet\u27s superiority to human grad- ing ability, is inconclusive in determining the success of our algorithm. These results leave open the path for future work to leverage the relative success of quality-diversity while accounting for the shortcomings of route quality and difficulty present in our system\u27s design
The Relationship Between Hospital Affiliation and Patient Welfare
No full textHealthcare is a unique industry due to the high-level of governmental involvement and its importance to national economies and wellness. Policies that result in low reimbursement rates, low patient volumes, staffing shortages, and strict regulations have led many hospitals, primarily rural ones, to precipice of closure. Losing a hospital can be damaging for a community as it can greatly reduce access to care, worsen the quality of care, and increase healthcare costs overall. Many hospitals choose to affiliate with other provider organizations in order to avoid closure and/or improve their finances. While agreements can supply hospitals with additional resources, affiliation can also rob rural hospitals of their autonomy. This hinders hospitals\u27 ability to address the needs of the communities that they serve. Additionally, health systems using hospital affiliation to expand into new markets exhibit, monopolistic behavior through horizontal integration. The effects of the affiliation trend have been studied more commonly from the hospital\u27s perspective, as opposed to the patient\u27s. Thus, this paper will investigate how hospital affiliation affects patient welfare. Patient welfare is defined along three axes, cost, access, and quality. A panel regression analysis was used to uncover the result of hospital affiliation on these three categories. The analysis showed that costs increase, access increased, and quality decreased
