Applied synectics to teach community development for living and learning communities to resident advisors and community assistants at California State University Monterey Bay
This action research investigated the use of the synectics instructional model to teach community development to Resident Advisors and Community Assistnats at California State University Monterey Bay. Feedback from participants of the trainings was collected using online surveys and focus groups. The teacher-researcher also maintained a reflective journal of the training sessions. Findings supported that synectics promoted concept development and creative thinking and was a useful problem solving tool to organize training sessions and schedules. The research suggested combining the synectic models and adding more learning strategies improved the effectiveness of the model for teaching and learning
Geographic Variation in Temperature Tolerance as an Indicator of Potential Population Responses to Climate Change
The temperature tolerances of individuals in geographically separated populations of a single species can be used as indicators of each population\u27s potential to persist or become extinct in response to climate change. We evaluated the population-level variation in temperature tolerance in populations of several marine invertebrate taxa, including bryozoans, tunicates, bivalves, and gastropods, separated by distances of \u3c 200 km to \u3e 5000 km. We then combined physiological thermotolerance data with current temperature data and climate change predictions to predict which of these populations may be most vulnerable to future changes. In a trans-continental comparison of four subtidal epibenthic species, we show that populations on the east coast of the United States, which experienced higher habitat temperatures than those on the west coast, had higher thermal tolerances but lived closer to individuals\u27 tolerance limits. Similarly, temperature tolerances varied between western and eastern Atlantic populations of the mussel Mytilus edulis; however, these differences only emerged after repeated exposures to high temperatures. Furthermore, the less thermotolerant M. edulis population in the western Atlantic was more susceptible to temperature increases, as evidenced by a recent range contraction. Thus, for both the subtidal epibenthic and intertidal mussel species, we identified the western Atlantic as a âhot spotâ of populations susceptible to climate change compared to those in the eastern Pacific and eastern Atlantic, respectively. Finally, because current tolerances are not the sole indicators of individuals\u27 abilities to cope with temperature increases, we also assessed the possibility for acclimatization to facilitate the persistence of populations via the buffering of temperature effects. We show that, for four populations of intertidal Littorina snail species in the northwest Atlantic, most populations were able to overcome geographic differences in temperature tolerance via acclimation. When acclimation capacity is low, the potential for ârescueâ may depend on the particular species\u27 life-history strategy and dispersal ability. For example, although individuals from the coldest-adapted population of Littorina littorea were unable to acclimate as quickly as those from more southern populations, this species has a pelagic larval stage and, thus, the greatest dispersal potential of these littorines. Together, these studies highlight the importance of considering variation in temperature tolerance between populations within species to improve the forecasting of changes in the abundances and distributions of species in response to climate warming
Accommodation Use by Individuals with Disabilities in Occupational Therapy Fieldwork
The number of individuals enrolling in postsecondary education with a diagnosed disability is rising. However, the literature reflects a gap between mandated institutional policies and the extent of accommodation use and success. This study examines the use, type, and prevalence of accommodations used by students with disabilities completing occupational therapy fieldwork rotations, as well as the common barriers to accommodation access. Snowball sampling methodology was utilized to send out a 26-item questionnaire to occupational therapists and occupational therapy assistants. Two hundred and ninety-two occupational therapists and occupational therapy assistants answered the questionnaire to identify disability type, disclosure of disabilities, and types of accommodations used during fieldwork. Results indicated that 47 respondents (16.91%) reported having either a visible and/or invisible disability but of those respondents, only 25 (55.56%) disclosed their disability during postsecondary education. Of the respondents who identified having a disability during fieldwork, 22 (51.16%) perceived that their disability presented challenges, while only 17 (38.64%) requested accommodations. As more than half of respondents felt their disability presented challenges during their fieldwork, strategies are suggested to encourage students to feel more comfortable disclosing their disability. Through creating a culture of openness to disabilities and understanding individual student needs, there is a potential to help increase the rate of disclosure of disability and potentially decrease some of the challenges experienced by students with disabilities on fieldwork. Further research is needed to develop guidelines and programming for fieldwork educators on how to best incorporate accommodations into their programs

Divas negras, feminismos negros: el âhabla de negrosâ y el cuerpo de las mujeres negras en Lope de Rueda
In this paper I focus on black feminist theory and offer a racially gendered analysis attuned to the intersectional discourse of gender, language, and race on display in early modern Spanish representations of black women in Lope de Ruedaâs Eufemia (1542/1554) and Los enganÌados (1538/1558). I treat the two black female charactersâEulalla and Guiomarâas authoritative black female subjects, or âdivas.â As divas, these charactersâ notoriety and marketability enables them to access the (Spanish) nation as so-called royalty and queens, which hinges on a somatic Blackness that is fluid and performative yet deceptive and paradoxical. Manifested in their habla de negros speech, Eulalla and Guiomar speak with witty verbal puns and exhibit audacious bodily performances representative of Renaissance self-fashioning in relationship to cosmetics, female agency, and material objects such as books, makeup, and exotic animals. I suggest that Ruedaâs portrayal of these characters might serve as a beacon for todayâs scholars of early modern Spain to augment their initial critical approach to analyzing black women in the literature of Renaissance Europe. Just as Eulalla and Guiomar marveled sixteenth-century Spanish audiences with their contestatory power, they will also illuminate black womenâs claims to female authorship for present-day readers.En este trabajo utilizo teorĂa feminista negra para ofrecer un anĂĄlisis racial y de gĂ©nero âen sintonĂa con los discursos de interseccionalidad lingĂŒĂstica, feminista y racialâ de las representaciones de mujeres negras en la modernidad temprana española. EspecĂficamente, analizo las obras Eufemia (1542/1554) y Los enganÌados (1538/1558), del dramaturgo Lope de Rueda. Considero a sus dos protagonistas negras âEulalla y Guiomarâ como sujetos negros femeninos autorizados o âdivasâ. En su calidad de divas, la notoriedad de estos personajes les permite acceder a la naciĂłn (española) como si fueran parte de la ârealezaâ, dependiente esta de una negritud somĂĄtica que es fluida y performativa, pero tambiĂ©n engañosa y paradĂłjica. El habla de negros caracterĂstica de Eulalla y Guiomar se despliega en ingeniosos juegos de palabras y audaces representaciones corporales de autofiguraciĂłn renacentista, agencia que se sostiene mediante el uso de cultura material como los libros, los cosmĂ©ticos y los animales exĂłticos. Sugiero que la representaciĂłn que Rueda hace de estos personajes puede servir como guĂa para ampliar la aproximaciĂłn crĂtica de los estudios sobre la temprana modernidad española mediante un anĂĄlisis crĂtico de las mujeres negras en la literatura renacentista europea. Del mismo modo en que Eulalla y Guiomar maravillaron al pĂșblico español del siglo XVI con su poder contestatario, tambiĂ©n pueden reivindicar su agencia femenina como mujeres negras a ojos de los lectores actuales

Relief of the Dma1-mediated checkpoint requires Dma1 autoubiquitination and dynamic localization
© 2018 Jones, Chen, et al. Chromosome segregation and cell division are coupled to prevent aneuploidy and cell death. In the fission yeast Schizosaccharomyces pombe, the septation initiation network (SIN) promotes cytokinesis, but upon mitotic checkpoint activation, the SIN is actively inhibited to prevent cytokinesis from occurring before chromosomes have safely segregated. SIN inhibition during the mitotic checkpoint is mediated by the E3 ubiquitin ligase Dma1. Dma1 binds to the CK1-phosphorylated SIN scaffold protein Sid4 at the spindle pole body (SPB), and ubiquitinates it. Sid4 ubiquitination antagonizes the SPB localization of the Polo-like kinase Plo1, the major SIN activator, so that SIN signaling is delayed. How this checkpoint is silenced once spindle defects are resolved has not been clear. Here we establish that Dma1 transiently leaves SPBs during anaphase B due to extensive autoubiquitination. The SIN is required for Dma1 to return to SPBs later in anaphase. Blocking Dma1 removal from SPBs by permanently tethering it to Sid4 prevents SIN activation and cytokinesis. Therefore, controlling Dma1âs SPB dynamics in anaphase is an essential step in S. pombe cell division and the silencing of the Dma1-dependent mitotic checkpoint
Adolescent Positivity and Future Orientation, Parental Psychological Control, and Young Adult Internalising Behaviours during COVID-19 in Nine Countries
The COVID-19 pandemic disrupted many young adultsâ lives educationally, economically, and personally. This study investigated associations between COVID-19-related disruption and perception of increases in internalising symptoms among young adults and whether these associations were moderated by earlier measures of adolescent positivity and future orientation and parental psychological control. Participants included 1329 adolescents at Time 1, and 810 of those participants as young adults (M age = 20, 50.4% female) at Time 2 from 9 countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). Drawing from a larger longitudinal study of adolescent risk taking and young adult competence, this study controlled for earlier levels of internalising symptoms during adolescence in examining these associations. Higher levels of adolescent positivity and future orientation as well as parent psychological control during late adolescence helped protect young adults from sharper perceived increases in anxiety and depression during the first nine months of widespread pandemic lockdowns in all nine countries. Findings are discussed in terms of how families in the 21st century can foster greater resilience during and after adolescence when faced with community-wide stressors, and the results provide new information about how psychological control may play a protective role during times of significant community-wide threats to personal health and welfare
