New Records of Aulacigaster neoleucopeza Mathis and Freidberg (Diptera: Schizophora: Aulacigastridae) from Wisconsin
Full text linkIn Wisconsin, Aulacigaster neoleucopeza was previously known from but a single Dane County record dating from April 1951. We report one specimen captured with a flight-intercept trap on private property in Lafayette County, five specimens recovered from Lindgren funnel and Malaise traps at the Hemlock Draw, Nature Conservancy Preserve in Sauk County, and 659 specimens from Malaise traps at the Quincy Bluff State Natural Area in Adams County. The specimens were taken from mid-April 1998, late April to mid-May 2014, and early to mid-April 2010, respectively. A
Seasonal Flight Patterns of Hemiptera in a North Carolina Black Walnut Plantation. 1. Pentatomoidea
Full text linkThe seasonal flight patterns of 35 species and subspecies of Pentatomoidea collected in window traps in a North Carolina black walnut plantation are discussed. Flying height distributions and seasonal activities of the five species that were most frequently collected (i.e., Amnestus basidentatus, A. pallidus, A. spinifrons, Brochymena qltadripustulata and Euschistus servus) are considered in detail
The Biology of the White Pine Sawfly, Neodiprion Pinetum (Hymenoptera: Diprionidae) in Wisconsin
Full text linkThe white pine sawfly, Neodiprion pirletunl. is monophagous on eastern white pine, Pinus strobus, throughout its range in eastern North America. Localized outbreaks occur frequently, and small areas of white pine may be killed. The high population upsurge in Crawford County. Wisconsin, in 1978 was mitigated by the eulophid egg parasite, Closterocerus cinctipennis, when a mean 90.1 t 4.870 parasitization occurred. Larval parasitization in the Grant County infestation averaged 45.05%. and involved the ichneumonid, Olesicampe lophyri, the perilampid Perilamplts l~yalirllcs, and the tachinid Spathimeigenia erecta
Corixid Transients on Stream Riffles (Hemiptera: Corixidae)
Full text linkFive genera and 12 species of corixids were collected from riffle regions of the Forest River, North Dakota, from summer of 1970 to fall 1971. Their occurrence, ecology, succession, and seasonal abundance in headwaters is discussed
Improving Hospital Discharges Before Noon: Implementation of a VIDA (Very Important Discharge Appointment)
Full text linkDelays in hospital discharge can negatively affect hospital throughput and bed capacity, resulting in increased length of stay and boarding of patients in off-unit locations which causes concerns for patient safety and potential harm (Rutherford et al., 2017). The purpose of this DNP project was to determine if the implementation of a very important discharge appointment (VIDA) would increase the number of hospital discharges occurring before noon (DBN) each day. This project was implemented at a 350-bed academic medical center in East Central Indiana. A 25-bed, adult medical unit served as the pilot unit. In total, 538 patients were included for this evidence-based project with 145 (27%) patients receiving the intervention, and 393 (73%) patients not receiving the intervention. Patients were selected to receive the intervention based upon medical stability and transportation availability the day of discharge. The primary intervention consisted of scheduling a VIDA for the patient on the day of discharge to increase the likelihood that the patient would be discharged before noon. Data was collected within the group pre-intervention and post-intervention. VIDA patients were tracked, and discharge time of day was recorded. Data between the two groups were analyzed using the Wilcoxon-Mann-Whitney test and chi-squared test. An odds ratio was then used to quantify the strength of the association between the two groups. Of the 145 patients receiving the intervention, 97 (67%) were discharged before noon. Of the 393 patients not receiving the intervention, 24 (6%) were discharged before noon. There was statistical significance of an association between the intervention and a patient being discharged before noon (p \u3c .001). Patients receiving the intervention were 30.6 times more likely to be DBN as patients not receiving the intervention (95% CI: 18.12 - 53.57). These findings suggest that implementing a structured discharge appointment process, such as VIDA, is an effective strategy for improving hospital patient flow in similar healthcare settings
Diversity and Activity of Ground-Dwelling Spiders (Araneae) in Four Sub-Communities in a Degraded Oak Woodland at the Chicago Botanic Garden, Cook County, Illinois
Full text linkGround-dwelling spiders were sampled using pitfall traps over a twelve-month period from four sub-communities within a 40-ha oak woodland complex in northern Cook County, Illinois. Mesic and dry mesic oak woodland, mesic upland forest, buckthorn dominated mesic oak savanna and a mesic woodland control, where no restoration management is planned, were sampled. Fifty-five species within 44 genera and 18 families were trapped. The results suggest negative correlations between non-native spider abundance and spider species richness. Also, phenology of the various species indicates that a year-round inventory is necessary to adequately sample ground-dwelling spider assemblages. Possibilities of using Bathyphantes concolor (Wider) abundance as an indicator of oak woodland recovery are discussed. Three species, Linyphiidae: Oreonetides vaginatus (Thorell), O. rotundus (Emerton), and Thomisidae: Ozyptila praticola C. L. Koch), never before recorded for Illinois were documented. The non-native species, Ozyptila praticola, is also a new regional record
Discovering New Plant-Based Compounds To Treat Oral Diseases: An Independent Research Project
Full text linkInfectious diseases are cited as one of the main causes of death worldwide. Many drugs to treat such illnesses were discovered in the mid-1900s, but this type of research has declined in recent years. At the same time, antimicrobial-resistant “superbug” infections are on the rise, including superbug biofilms present in the oral cavity, which are responsible for diseases such as tooth decay, gum disease, and implant failure. Therefore, I have been working to explore various plants from a medicinal garden on the Valparaiso University campus to screen extracts against common disease-causing oral bacteria with the goal of discovering novel compounds to fight these illnesses. Several of these extracts have shown promising antimicrobial effects specifically against Gram-positive bacteria, and the results will be presented in this poster. Future work will focus on separating several promising extracts using column chromatography to identify novel plant compounds relevant in dental health. This is a self-proposed project that I have received internal funding to work on via a CWR Guild Undergraduate Research Expense grant from my institution. I am very excited about this work due to my ambition to attend dental school
Reported Bias Incidents in Northwest Indiana: An Examination of Newspaper Accounts
No full textThis exploratory study investigates bias-motivated incidents in and around the City of Valparaiso, Indiana, over the past 30 years. The study aims to examine patterns and trends in such incidents, defined broadly as bias-motivated incidents rather than the more narrowly defined hate crimes. While hate crimes, according to the FBI, involve criminal offenses motivated by bias against race, religion, disability, sexual orientation, or ethnicity/national origin, bias-motivated incidents encompass any behavior expressing hostility toward individuals or property based on these characteristics, regardless of whether they rise to the level of criminal activity. The research analyzes reports of these incidents as documented in regional newspaper coverage, focusing on the frequency, location, type, and severity of incidents. The study does not include other sources and is therefore exploratory in nature, suggesting that further research using a broader range of data sources is necessary for a more comprehensive understanding. This investigation seeks to highlight patterns in bias-motivated incidents and encourage future studies to develop a more complete database of such occurrences
Crisis at the Stand and on the Streets: Understanding the Intersections Between Substance Abuse and Criminalization in Competency Outcomes Amongst People Experiencing Homelessness
No full textThe criminalization of homelessness is a phenomenon that took root in the United States during the late 20th century, making people experiencing homelessness more likely to face legal issues. Because people experiencing homelessness are more likely to experience a myriad of mental health problems, they sit at the intersection of the criminalization of poverty and of mental illness. As such, when they make contact with the criminal justice system, they may have more involvement with competency to stand trial (CST) cases– an evaluation used to determine if a defendant is able to defend themselves and to comprehend the charges they face. This is one of the factors hypothesized to contribute toward the national competency crisis– where there are too few evaluators for the number of CST cases. This study aims to investigate the relationship between homelessness, CST referrals, and CST outcomes. Using the Odyssey Public System, this study had access to a population of over 4000 CST evaluations in one Midwestern state and sampled 139 of these evaluations for the current research question. Using mycase.in.gov, student research assistants coded additional data about the case (including specific charges, whether the defendant was homeless, and the outcome of CST in those cases). This presentation will review the background of this growing problem, identify how many CST evaluations involve homeless individuals, and examine the outcomes of those cases. The study anticipates that people experiencing homelessness will both be more likely to experience CST referrals and incompetent evaluations
