Paleoenvironment of the Late Eocene Chadronian-Age Whitehead Creek Locality (Northwestern Nebraska)
Toward the end of the Middle Eocene (40-37mya), the environment started to decline on a global scale. It was becoming more arid, the tropical forests were disappearing from the northern latitudes, and there was an increase in seasonality. Research of the Chadronian (37-33.7mya) in the Great Plains region of North America has documented the persistence of several mammalian taxa (e.g. primates) that are extinct in other parts of North America. This research aims to investigate the paleoenvironment of the Whitehead Creek locality, Nebraska, one Chadronian-age locality within the Great Plains, in order to better understand the circumstances surrounding the persistence of relict taxa during the late Eocene. To address the paleoenvironment at Whitehead Creek, this research evaluates locomotor guilds of 56 astragalar morphospecies, 43 calcaneal morphospecies, and a sample of 55 terminal phalanges. To evaluate paleoenvironment at Whitehead Creek, locomotor frequencies established for fossil morphospecies were compared with those found in 25 modern sites, representing a wide range of environments, using Sørenson’s similarity index and the Euclidean Distance method. Results indicate that small mammals (\u3c 1,000g) at Whitehead Creek practiced a wide range of locomotor activities including leaping, digging, climbing, and running in both arboreal and terrestrial habitats. Comparisons suggest that a gallery forest in the Cerrado of Brazil is a good modern analog for Whitehead Creek. The mixture of locomotor categories found at Whitehead Creek suggest that Whitehead Creek was a mosaic of water, overbanks, closed canopy forests (with an herbaceous understory), bamboo thickets and open woodlands
Constraining the Inclination of Binary Mergers from Gravitational-wave Observations
Much of the information we hope to extract from the gravitational-waves
signatures of compact binaries is only obtainable when we can accurately
constrain the inclination of the source. In this paper, we discuss in detail a
degeneracy between the measurement of the binary distance and inclination which
limits our ability to accurately measure the inclination using gravitational
waves alone. This degeneracy is exacerbated by the expected distribution of
events in the universe, which leads us to prefer face-on systems at a greater
distance. We use a simplified model that only considers the binary distance and
orientation, and show that this gives comparable results to the full parameter
estimates obtained from the binary neutron star merger GW170817. For the
advanced LIGO-Virgo network, it is only signals which are close to edge-on,
with an inclination greater than that will be distinguishable
from face-on systems. For extended networks which have good sensitivity to both
gravitational wave polarizations, for face-on systems we will only be able to
constrain the inclination of a signal with SNR 20 to be or less,
and even for loud signals, with SNR of 100, the inclination of a face-on signal
will only be constrained to . For black hole mergers observed at
cosmological distances, in the absence of higher modes or orbital precession,
the strong degeneracy between inclination and distance dominates the
uncertainty in measurement of redshift and hence the masses of the black holes
Bibliographic Induction: How KO Systems Optimize Browsing by Supporting Library Users' Prior Knowledge
We investigate category-based induction as an aspect of browsing a library collection. Category-based induction is one of the primary uses of categories that are stored in memory. Knowledge organizing systems represent concepts in broadly the same way as models of category-based induction. Accordingly, it is reasonable to suppose that knowledge organizing systems facilitate category-based inductions about the collections that they organize. The processes of familiarization and differentiation are key aspects of browsing (Ellis 1989). Intuitively, these approaches appear to involve category-based induction in a bibliographic context. By examining induction, we hope to shed new light on the role of knowledge organizing systems in shaping browsing behavior. We also seek to investigate the viability of using inductive confidence as a dependent variable in assessing the utility of a KOS. A system that supports induction is potentially of great benefit to people seeking to browse a collection, whether the collection exists virtually or is part of a library’s physical stacks
Community Isolation Project
Introduction
The authors of this summary are nursing students at Seattle Pacific University, and the project goal is focused on understanding feelings of isolation in elderly communities and whether fostering social activities, such as Bingo, would improve social interaction between residents in this community.
For the past two years, the COVID-19 pandemic has altered various aspects of social interaction. From masking to social distancing, societal norms and expectations evolved in a manner that promoted isolation and minimal interaction to inhibit the spread of Covid infection between individuals. Of the general populace, the most vulnerable and at risk for infection are the elderly and those with comorbidities. Subsequently, older individuals are more at risk for rigid social isolation precautions due to the risk of infection, affecting many of the individuals in this group who live in community settings such as nursing homes and long-term care facilities. This project ultimately seeks to understand how older individuals might feel after participating in community activities with one another as well as assess for any feelings of depression and social isolation post pandemic. Background
The population worked with is a subsidized living community for individuals over the age of 62. The 200-plus unit apartment complex is located in North Seattle just off the Aurora business district. Social isolation and loneliness in older adults living in communities such as this is a growing concern especially since the pandemic showing upwards of 29% of the elderly population to report being lonely in the U.S. (Taylor, et al., 2018). Although it is hard to precisely measure social isolation and loneliness, the evidence that does exist shows there is an increased risk for dementia alone, by fifty percent, with links to an increase in cardiovascular disease, stroke, anxiety, depression, and suicide (CDC, 2021). More recent studies in populations of older adults residing in senior housing communities seem to experience higher levels of loneliness due to lower-income, being alone due to the death of a spouse/partner, having fewer confiding relationships, depression, and other significant comorbidities as mentioned, as compared to those living in conventional housing (Taylor, et al., 2018). This is attributed to having less contact with family and friends, social anxiety of meeting neighbors, and altogether feeling of not being supported (Taylor, et al., 2018).
The COVID-19 pandemic added more barriers to social isolation and loneliness for the elderly due to early restrictions of in-person gatherings, recreational activities within the community, family gatherings being canceled, spiritual congregations canceled, and many deaths within the community, all adding to the sense of isolation, loneliness, and depression (Webb and Chen, 2021).
As far as interventions to combat loneliness and social isolation, there have been many. It is difficult to analyze due to individual experience surrounding the issues (Fakoya et al., 2020). There is not a “one-size-fits all” standardization to address social isolation and loneliness in the elderly, showing that tailoring interventions to specific community and individual needs as being the best approach (Fakoya et al., 2020).
Activities with Rationale
When discussing what activities or events the project should center around, the team collaborated with the property manager at the senior living community to ensure the provided activity would be both fun and engaging for the residents, as well as beneficial and information-producing for our project and the property manager. After it was determined the project would center around targeting loneliness in elderly communities, an idea was landed on creating an event that would demonstrate the importance of connection and combat isolation. A transtheoretical model of change was used as the basis for this project. This change model states that behavior change takes place through the following stages: precontemplation, contemplation, preparation, action, maintenance, and termination. To measure this, pre- and post- surveys were filled out by residents to gather data to support the health promotion project’s claims. The project at the community included two Bingo days. The specific activity was determined through popular request by the residents who had mentioned playing and enjoying Bingo as a community in the past. A week prior to the first event, pre surveys were distributed asking the residents about their experience of isolation and/or loneliness if they had any. Residents were incentivized to attend the Bingo events with promised coffee, snacks, and small prizes for Bingo winners. Residents were even given a chance to be entered into a randomized drawing for a fifteen-dollar gift card to Sprouts, a local grocery store, which was conducted at the end of each Bingo day. After the events, those who participated in Bingo were then further encouraged to fill out post surveys. These surveys questioned how it felt to engage in the community and if their feelings or loneliness/isolation had changed in order to assess the impact the bingo event had on mood and affect. For the purposes of this project, it was important not only to gather information, but to model what having community events, such as Bingo, could look like and how they would positively impact the community.
Outcomes
To gain a better understanding of how the community felt regarding loneliness, isolation, and their willingness to participate in group activities, pre- and post-bingo surveys were provided utilizing the Likert scale. In return, 30 pre-surveys were returned from the community. Following the event, 30 post-surveys were filled out by the residents who participated in Bingo. After reviewing the results of the pre-surveys, it was concluded that the overall community often feels a sense of loneliness, but they have an ardent desire to participate in group activities. After 2 days of Bingo, residents who joined us were asked to fill out a post-survey to gauge if the group activity had any effect on them. In almost every single post activity survey received, residents answered that playing Bingo with their community positively impacted their mental health, they would play Bingo or attend another event again, and they found it easier to build relationships with their community members while engaging in Bingo together. The community engagement surveys revealed that group activities such as bingo led to an outcome of decreased loneliness and isolation. According to the data collected, hosting and facilitating social events, specifically for older adult populations, post pandemic, is extremely beneficial to mental health and overall wellness.
Conclusion
Although Covid has been around for two years now, it has proven to be very difficult to navigate, especially in community settings such as this subsidized living community. This pandemic has been exceptionally problematic as facilities search for a balance betweenl encouraging social activity, and also promoting physical safety from Covid-19. While preventing the spread of the virus is certainly a priority, mental health, arguably, is just as crucial to one\u27s well-being as their physical health.
The surveys collected in this project revealed that while many individuals had a strong urge to engage in social activities, a sense of loneliness in the community still exists for many people. As mentioned in other studies, there’s no “correct” way to decrease feelings of isolation as the process of overcoming this sense of remoteness may be very specific to the community. Luckily, the staff at this site are very in tune with their population and they disclosed that Bingo is a popular activity among the residents. It was important that the activity was appropriate and engaging for people of all different backgrounds as the intent of the project was to foster community engagement and improve social interactions among the group. Overall, there was a great turnout of people at both the first and second Bingo events, further exemplifying the enthusiasm many individuals shared about wanting to be more engaged in the community.
Because there was such a big turnout, the group had a few challenges to overcome. Firstly, accessibility and navigation within the conference room was a little tight the first time around which the group was able to overcome by rearranging tables to accommodate for walkers and wheelchairs. Secondly, while there was a provided space and Bingo set, the budget for prizes and snacks was also very limited which led to the group contributing personal funds to the project. Lastly, while the post-surveys offered great insight, they provided information on a very small percentage of the population. The results of the surveys are from the perspective of individuals who most likely often attend group activities, which ultimately skews the information as this may not accurately represent the entirety of the population at this senior community. For a more accurate representation of the community, there would need to be a larger sample number.
The project proved to be successful as many of the residents answered in their post-surveys that the Bingo event decreased feelings of loneliness and isolation, therefore positively impacting their mental health. Many of the individuals also stated in their questionnaires that they would attend more Bingo events in the future. In addition, residents were also eager to suggest other fun group activities such as painting, gardening, picnics, and dances. Moving forward, it would be beneficial for future groups to try other activities in addition to Bingo. Different events may motivate social interaction from the individuals who don’t enjoy activities such as Bingo and would facilitate a feeling of excitement in anticipation for a communal gathering that is both entertaining and interactive. This health promotion project found Bingo to be a successful event in which participants were able to maintain a safe social distance, and engage together in a fun, community activity.

Ketogenic diets as an adjuvant therapy for glioblastoma (KEATING): a randomized, mixed methods, feasibility study
This is a post-peer-review, pre-copyedit version of an article published in Journal of Neuro-Oncology. The final authenticated version is available online at: http://dx.doi.org/10.1007/s11060-020-03417-8Purpose We conducted a feasibility study to investigate the use of ketogenic diets (KDs) as an adjuvant therapy for patients
with glioblastoma (GBM), investigating (i) trial feasibility; (ii) potential impacts of the trial on patients’ quality of life and
health; (iii) patients’ perspectives of their decision-making when invited to participate in the trial and (iv) recommending
improvements to optimize future phase III trials.
Methods A single-center, prospective, randomized, pilot study (KEATING), with an embedded qualitative design. Twelve
newly diagnosed patients with GBM were randomized 1:1 to modifed ketogenic diet (MKD) or medium chain triglyceride
ketogenic diet (MCTKD). Primary outcome was retention at three months. Semi-structured interviews were conducted
with a purposive sample of patients and caregivers (n=15). Descriptive statistics were used for quantitative outcomes and
qualitative data were analyzed thematically aided by NVivo.
Results KEATING achieved recruitment targets, but the recruitment rate was low (28.6%). Retention was poor; only four
of 12 patients completed the three-month diet (MCTKD n=3; MKD n=1). Participants’ decisions were intuitive and emotional; caregivers supported diet implementation and infuenced the patients’ decision to participate. Those who declined
made a deliberative and considered decision factoring diet burden and quality of life. A three-month diet was undesirable to
patients who declined and withdrew.
Conclusion Recruitment to a KD trial for patients with GBM is possible. A six-week intervention period is proposed for a
phase III trial. The role of caregiver should not be underestimated. Future trials should optimize and adequately support
the decision-making of patients
