Maia Campbell, Ally Lankford | Temperature Controls on Microcystin Degradation

symposium_cyanotoxin degradation poster.pdf

Toxic cyanobacteria blooms are increasing in frequency and severity with rising surface-water temperatures. Warming generates a positive feedback on harmful algal bloom  development by promoting toxic cyanobacteria over non-toxic strains, stimulating toxin synthesis, and subsequently triggering toxin release. The release of cyanotoxins into the water column poses a serious threat to water quality and human health. Yet, cyanotoxins rarely accumulate in the water column long-term, suggesting that biodegradation by heterotrophic bacteria may play a role in the removal process. Owing to increased metabolic rates at higher temperatures, microbial-mediated degradation of cyanotoxins may be influenced by warming. However, the effect of warming on the uptake and subsequent biodegradation of cyanotoxins has not yet been evaluated. In this study, we evaluated the ability for heterotrophic bacteria to degrade microcystin produced by a common cyanobacterium, Planktothrix agardhii, across a natural temperature gradient (from 5 to 20° C) during a laboratory incubation experiment. We measured microcystin concentration and bacterial abundance at 0, 6, 12, 24, 48, 96, and 192 hours. We found that microcystin concentration declined over time in all temperature treatments and degradation increased with warming. Patterns of microcystin degradation corresponded with increases in bacterial cell density over time that were enhanced by warming. Bacterial cell density increased most rapidly in the 20°C treatment resulting in the greater microcystin degradation than all other treatments. Degradation of microcystin was lowest in the 5°C treatment where the increase in bacterial cell density was the slowest. Bacterial density and microcystin degradation were similar between 10°C and 15°C treatments throughout the experiment and were consistently between 20°C and 5°C treatments. These results suggest that cyanotoxins can be reduced by microbial-mediated degradation and the rate of cyanotoxin degradation increases with water temperature.

Mariah Bowman | Eliminating Mental Health Stigma on Ball State's Campus

https://i.ytimg.com/vi/0KjN718uRrk/default.jpg

The stigma associated with mental illness describes the shame placed on those experiencing a mental disorder or seeking help for distress. The three types of stigma help spread stereotypes and prejudices to individuals facing these issues, which results in reduced hope, lower self-esteem, and more difficulties with relationships and every-day activities. The community needs to continue focusing on the education of mental illness, as well as provide resources for those experiencing a disorder. By addressing both parties, society becomes more accepting of mental disabilities, which ends in more people openly seeking help without embarrassment.

Mariah Grange, Lauren Wake | Infant Hearing and Postpartum Depression/Anxiety Screening: An Inter-Professional Approach

SS6.png

Abstract: Postpartum depression (PPD) is a condition that people know little about. One in every seven women experience PPD postnatally. Health professionals and family members may be unaware of specific signs, symptoms, red flags, and risk factors that occur with PPD. In the United States, mothers do not usually see their primary doctor until about six weeks after giving birth. This means that for many of these mothers with PPD, they could potentially be going up to six weeks without receiving any care for their depression. Before COVID-19, our original study was to identify mothers who may be experiencing PPD during their infant's follow-up hearing appointment, and guide them to seek help. The second goal was to educate other health professions on the importance of screening mothers for PPD. Due to COVID-19 we continued with the Inter-Professional Education Event (IPE) portion of our original project, which included other professions in the College of Health.

Martina Schiavo | Benefits on Listening and Speaking in Learning English through International Programs’ Activities

The paper discusses the alignment of learning objectives with speaking and listening skills, materials, and assessments. They are developed through participation in international students' presentations with their faculty studying at the Intensive English Institute (IEI). These presentations are part of social events organized by the International Office called Rinker Center for International Program (RCIP) at Ball State University in Muncie, Indiana. The goal is to improve speaking and listening skills, the most difficult to develop in classroom activities. The methodology was based on a survey measuring the efficacy of the objectives addressing speaking and listening skills. The survey results conducted among instructors provided clear evidence that future participation in these events will consolidate cultural knowledge, pronunciation, and taking notes skills in front of a speaker despite time constraints of the IEI. These results were valid in alignment with the learning objectives of speaking and listening. Regarding the material to prepare ahead and the assessments, relevant ideas were pointed out both in the close-ended and open-ended questions. This research is framed in the more general importance of a collaboration between the English Institute of a university and the International Office because many international students attending a university in the US at least in Indiana attend the English Institute. This collaboration becomes essential in building students’ intercultural competence and communicative skills to succeed both in real life and at the academic level.

Mitchell Kissick, Anthony Milesi | Noise Induced Hearing Loss in Recreational Firearm Users

Ball State Logo.png

Recreational firearm users are exposing themselves to prolonged and repeated sound intensity levels that are considered dangerous to human hearing. While many shooting ranges and gun clubs require shooters to wear hearing protection while shooting is going on, often the type of hearing protection devices appropriate to the sound levels shooters are exposed to are not clear. Another consideration is that while someone may use hearing protection devices (HPDs) while at shooting ranges or gun clubs, they may be less likely to do so on their own property. This study sought to determine what attitudes of local recreational shooters are towards hearing protection devices and noise induced hearing loss, as well as to determine if there were differences in the attitudes of different age groups through the use of a survey. Another goal of this study is to use information obtained from survey responses to aid the researchers in catering hearing conservation information for shooters that is more finely focused on local attitudes and any adjustments that may need to be made to these attitudes. The hearing conservation information will then be distributed to local shooting ranges and gun clubs, as well as through social media. In general, survey responses indicate that there are some differences between age groups, though further research is needed.

Nicholas Burrell, Brayden Gates, Joshua Johannsen, Eli Sokeland | A Design on Rating Apprentices and Analyzing Growth

LoginPage.png

Through the use of this project, an individual in a company will be able to create new users (designating them as an apprentice, full-time employee, or admin) on the service, add new ratings to each user in specific categories that an admin or a full-time employees creates, view the overall ratings of all users, and will allow admins and full-time employees the ability to view a specific apprentice's individual ratings in each category with a graph that shows the ratings over time to see if an apprentice is getting better at the skills they are developing in the workplace.

Nicholas L. Mundell, Anna Harp, Audrey Hasser, Lauryn Jones, Mary Scott, Jon Sorgenfrei | Gender Differences in MMPI-2-RF Scale Scores in College Students

Internalizing disorders are characterized by several negative symptoms including stress, anxiety, and mood instability (Ben-Porath, 2012; Duffy et al., 2017). The literature suggests that more women than men are diagnosed with internalizing disorders like depression (Nolen-Hoeksema, 1994). One mechanism that has been supported as influencing this difference is gender stereotypes, which encourage women and men to express emotions differently (Rosenfield et al., 2000). One specific area within the internalizing spectrum where we may see these gender differences is anger proneness. Anger proneness (ANP) is the tendency to become easily angered, upset, or impatient with others (Ben-Porath, 2012). Indeed, there is evidence to suggest that men tend to express anger more externally whereas women tend to express anger more internally (Dawson et al., 2010).

Despite past research on gender differences in internalizing disorders, previous literature has not examined gender differences in specific scales like the MMPI-2-RF ANP scale. Thus, the current study examined whether gender differences exist on the MMPI-2-RF ANP scale. We hypothesized that men would score higher than women. To achieve this goal, we used an archival dataset of college students who scored higher than average on the MMPI-2-RF Emotional/Internalizing Dysfunction scale. The assumption of normality for an independent samples t-test was violated so, we conducted an independent samples Mann-Whitney U test. The independent samples Mann-Whitney U test indicated that women and men endorsed similar levels of anger proneness, p=.72.

The MMPI-2-RF ANP scale captures negative emotional experiences of anger, but not how individuals act on these emotions. So, gender differences in anger may be better captured by the MMPI-2-RF Aggression scale which measures aggressive behaviors in response to feelings of anger. It may be that women and men experience feelings of anger similarly, but act on these emotions differently. For example, one’s culture and adherence to stereotypes affects the extent to which they engage in stereotype-consistent behaviors (Eagly et al., 2019). Thus, we may have a sample who more loosely adheres to gender stereotypes and therefore engages in fewer stereotype-consistent behaviors. Future research should investigate the effect of stereotypes on anger-related behaviors when other characteristics are accounted for.

Nilima Hakim Mow | Bangla-English Code-switching on Facebook: Features and Frequency

The world has been exposed to English in wider measure than ever before due to its huge role in technology and electronic communication. Due to this extensive contact with English, variation in the language in social media has resulted. Code-switching is one such result.

The focus of this exploratory study is to analyze the nature of Bangla-English code-switching in language use in the social medium Facebook, by Bangla speakers from Bangladesh. In order to do that, this study examines the features and frequency of Bangla-English code-switching on Facebook. Specifically, it analyzes the use of lexical items, phrases, and the frequency of switching. 

Bangla-English code-switching has been explored very little. Alam (2006) points out a few factors that motivate code-switching. Khadim (2014) investigates the motivation behind this practice focusing on the specific situations that might encourage code-switching. Tasnim (2018) investigates the frequency of code-switching based on a very small amount of data. My study aims to fill some gaps in previous research by examining the main features of code-switching along with the frequency of the words and phrases used.

A mixed methodology has been used to fulfill the objectives of the research. Data was collected through a survey questionnaire and close observation. Ten active users of Facebook have been chosen as participants through the snowball method for close observation. 

The data analysis yields result suggestive of the frequency and types of code-switching and their patterns of switching in language use on Facebook in terms of lexical, morphological, and syntactical properties.
