Description
Americans spend upwards of 90% of their time indoors, hence indoor air quality (IAQ) and the impact of IAQ on human health is a major public health concern. IAQ can be negatively impacted by outdoor pollution infiltrating indoors, the emission of indoor pollutants, indoor atmospheric chemistry and poor ventilation. Energy saving measures like retrofits to seal the building envelope to prevent the leakage of heated or cooled air will impact IAQ. However, existing studies have been inconclusive as to whether increased energy efficiency is leading to detrimental IAQ. In this work, field campaigns were conducted in apartment homes in Phoenix, Arizona to evaluate IAQ as it relates to particulate matter (PM), carbonyls, and tobacco specific nitrosamines (TSNA).
To investigate the impacts of an energy efficiency retrofit on IAQ, indoor and outdoor air quality sampling was carried out at Sunnyslope Manor, a city-subsidized senior living apartment complex. Measured indoor formaldehyde levels before the building retrofit exceeded reference exposure limits, but in the long term follow-up sampling, indoor formaldehyde decreased for the entire study population by a statistically significant margin. Indoor PM levels were dominated by fine particles and showed a statistically significant decrease in the long term follow-up sampling within certain resident subpopulations (i.e. residents who reported smoking and residents who had lived longer at the apartment complex). Additionally, indoor glyoxal and methylglyoxal exceeded outdoor concentrations, with methylglyoxal being more prevalent pre-retrofit than glyoxal, suggesting different chemical pathways are involved. Indoor concentrations reported are larger than previous studies. TSNAs, specifically N'-nitrosonornicotine (NNN), 4-(methyl-nitrosamino)-4-(3-pyridyl)-butanal (NNA) and 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanone (NNK) were evaluated post-retrofit at Sunnyslope Manor. Of the units tested, 86% of the smoking units and 46% of the non-smoking units had traces of at least one of the nitrosamines.

Description
The degree to which adolescents describe themselves as gender typical, as defined by their interests, activities, personal qualities, and other characteristics, is related to a broad range of adjustment indices. The goal of this thesis was to review studies conducted between 2000 and 2017 to provide a summary and critique of this research. A total of 18 studies were reviewed. The majority of findings indicate a positive association between gender typicality and beneficial adjustment outcomes, and a negative association between gender typicality and poor adjustment outcomes. Suggestions for future research and clinical implications of these findings are discussed.

Description
To investigate the impacts of an energy efficiency retrofit, indoor air quality and resident health were evaluated at a low‐income senior housing apartment complex in Phoenix, Arizona, before and after a green energy building renovation. Indoor and outdoor air quality sampling was carried out simultaneously with a questionnaire to characterize personal habits and general health of residents. Measured indoor formaldehyde levels before the building retrofit routinely exceeded reference exposure limits, but in the long‐term follow‐up sampling, indoor formaldehyde decreased for the entire study population by a statistically significant margin. Indoor PM levels were dominated by fine particles and showed a statistically significant decrease in the long‐term follow‐up sampling within certain resident subpopulations (i.e. residents who report smoking and residents who had lived longer at the apartment complex).

Description
Asian Americans are facing unprecedented and growing mental health issues brought by anti-Asian Racism and other forms of hyper-visible oppression (Yellow Horse et al., 2021). In response to racism, one potential solution for bolstering mental health outcomes among Asian Americans is critical reflection. Critical reflection is the process through which oppressed and marginalized people critically analyze oppressive social conditions (e.g., racism, sexism, and more) and consider actions they can take to change them (Watts et al., 2011). Recent research suggests that, overall, there is a strong link between critical reflection and the well-being of youth of color (Maker Castro et al., 2022). However, this relationship may vary based on additional factors, such as strategies used to cope with racism-related stress. For instance, Asian Americans with lower critical reflection about racism (e.g., as evidenced by endorsement of colorblind racial ideology, or the belief that racial differences are irrelevant and racism no longer exists) had a higher tendency to use avoidant coping mechanisms to deal with discrimination (Yi et al., 2022; Lewis et al., 2019). Additionally, there is other evidence to support that Asian Americans who held more colorblind racial attitudes experienced less anxiety when challenged with ambiguous discrimination compared to Asian Americans who held less colorblind racial attitudes (Lee, 2016). Overall, the literature suggests the importance of the relationship between critical reflection and mental health. However, studies have yet to quantitatively explore the impacts of critical reflection and strategies to cope with discrimination on mental health outcomes among Asian Americans (Spanierman et al., 2021) and young adults (Maker Castro et al., 2022).
The current study seeks to address this gap in the literature by examining the role of strategies to cope with discrimination in the relationship between Asian Americans’ critical reflection and mental health outcomes. It is crucial to explore these factors as Asian American students continue to shoulder prejudice, stereotypes, and systemic racism in professional and educational institutions. We hypothesize that the relationship between critical reflection and mental health will be mediated by the strategies used to cope with discrimination. More specifically, we expect that low levels of critical reflection (as indicated by high levels of color-blind racial attitudes) are related to greater use of internalization, substance use, and detachment strategies to cope with discrimination, which is related to greater endorsement of depression, anxiety, and stress symptoms.
Data for this study were drawn from a larger study on college students’ experiences in ethnic studies courses. Participants were 288 Asian Americans recruited from ethnic studies courses at universities in various regions of the United States. During the first two weeks of their ethnic studies course, participants completed an online survey about their racial attitudes, critical consciousness, and psychological well-being. Mediation analyses will be conducted using the PROCESS macro (Hayes, 2022) on SPSS version 27. Critical reflection, as measured by participants’ total mean score on the Color-Blind Racial Attitudes Scale (Neville et al., 2000; Keum et al., 2018) will be included as the independent variable; subscale scores on the Coping with Discrimination Scale (Wei & Alvarez, 2010) will be mediators; and each subscale of the Depression, Anxiety, and Stress Scale (DASS-21; Henry & Crawford, 2005) will be the dependent variable in separate analyses. Relationships between the study variables and Asian subgroup (i.e., East, Southeast, and South Asian) will also be examined.
While analyses are currently ongoing, preliminary findings suggest that strategies to cope with discrimination and mental health outcomes vary between East Asians, Southeast Asians, and South Asians. Additionally, preliminary findings suggest that the use of substance use and detachment to cope with discrimination explains the relationship between low critical reflection and mental health outcomes.
Findings have implications for encouraging mental health specialists and educators to have open conversations about racism while helping those who experience discrimination cope in healthy ways. Thus, this research can contribute to improved psychological well-being of Asian American young adults.

Description
The relationship between user experience, learning, and psychology is complex. There are many rules and concepts that guide experience design. It is likely that some of the guidance is valid whereas other guidance is not. This explores some of that guidance and evaluates how they are linked to learning. Do the guidance’s made 25, 50, 100 years ago still hold true today? Additionally, the psychological background behind the way someone holds memory is important. Knowing how information is stored and processed helps educators provide the best learning experience possible. With an eye toward perception and cognition, this paper examines the relevance of the various pieces of guidance. The results suggest that, overall, this guidance is still valid and valuable to current learning trends and designs. This suggests that user experience designers for education need to pay attention to the guidance provided by psychology when designing learning management systems, placing content in a course, and choosing which aesthetics to follow.

Description
Music and emotions have been studied frequently in the past as well as music and memory. However, these three items don’t have as much research grouped together. Further, this research does not also encompass culture. In my research, the aim was to examine the relationship between music, memory, emotion, and culture of gender. The hypothesis was that women had more emotions linked to music than men. We gave 416 students an animal fluency task, a letter fluency task, six cultural fluency tasks, and a cultural identity survey. We used a t-test and created a graph to analyze my data. After administering my tasks, we found that women had recalled more adjectives linked to music than men. However, there was not a statistically significant difference between the number of adjectives with emotional valence between men and women, indicating that there was no relationship between gender and emotion in regards to music. The limitations on this study included the descriptions on how to complete the task, the cultural norms of the participants, and the disparity between the number of female and male participants. In a future study, it is necessary to be more specific in what is desired from the participants and to pay close attention to shifting gender norms. Further, we would also like to see how the results from future research can impact music therapy for memory-related mood disorders.

Description
Particulate matter (PM) air pollution is a known factor to exacerbate cardiopulmonary diseases. We previously demonstrated that PM mediated endothelial injury and barrier disruption via modulation of the endothelial cytoskeleton and cell-cell junctions, while the effects of PM exposure on cell-cell communication and gap junction activity are still unknown. This study is focused on the characterization of PM-mediated endothelial dysfunction via Connexin 43 (Cx43), the most abundant Gap junction protein expressed in lung endothelial cells (ECs). PM exposure induces a time-dependent elevation of Cx43 in human lung ECs, at both mRNA and protein levels. N-acetyl-cysteine (NAC), an ROS scavenger, significantly suppresses PM-induced Cx43 expression. Membrane-associated and ER/ Golgi apparatus Cx43 protein are elevated upon PM challenge. In addition, PM also activates the gap junction activity, indicated by the transportation of green fluorescence dye between two adjacent ECs. Moreover, GAP27, a selective Cx43 channel inhibitor, attenuates PM-reduced human lung EC barrier disruption, measured by trans-endothelial electrical resistance (TER) with an electric cell-substrate impedance sensing system. Moreover, knock-down the expression of Cx43 by its selective siRNA alleviates PM-induced MLC phosphorylation. These results highly suggest that Cx43 plays a key role in PM-mediated endothelial barrier disruption and signal transduction. Cx43 may deputy as a therapeutic target in PM-mediated cardiopulmonary disorders.
