Looking Out, Looking In: Contemporary Artists from Morocco

This is the catalogue of the exhibition "Looking Out, Looking In: Contemporary Artists from Morocco" held at Faye G., Jo, and James Stone Gallery 855 Commonwealth Avenue from February 8, 2019 – March 31, 2019. The exhibition is curated by Cynthia Becker, Associate Professor of African Art, Boston University Department of History of Art and Architecture and Nadia Sabri, Professor of Art History and curator, Faculty of Education Sciences, University of Mohammed V in Rabat, Morocco. Participating artists are Hassan Darsi, Wiame Haddad, Hassan Hajjaj, Randa Maroufi, Safaa Mazirh, Lamia Naji, and Nour Eddine Tilsaghani.Looking Out, Looking In: Contemporary Artists from Morocco brings together seven diverse Moroccan photographers and videographers for the first time. Each works in a unique style and comes from a different background, but what links them is their exploration of how seeing is not always equated with knowing. They recognize that the process of looking is a political act and seek to emphasize the ambiguity of meaning contained within the visual. Some artists consider how Moroccan society is looked at by outsiders and confront the historical biases inherent in the colonial gaze. Others imagine a world without borders, making sense of the boundaries that divide nation-states. Some consider aspects of Moroccan culture hidden from public view due to political oppression. Each uses their art to contemplate the moral and emotional experiences of looking in at oneself in response to looking out at the complex social issues that impact Morocco today.The exhibition is co-sponsored with Boston University’s African Studies Center, the Boston University Arts Initiative, the Institute for the Study of Muslim Societies & Civilizations, the Department of History of Art & Architecture. The Boston University Art Galleries programs are supported in part through a grant from the Boston Cultural Council and administered by the Mayor’s Office of Arts and Culture

AN ANALYSIS OF THE QUALITY AND QUANTITY OF PARENT/CHILD READING UTTERANCES WHILE READING DIFFERENT GENRES

The purpose of this study was to investigate how different genres affect the quality and quantity of parent/child reading utterances. I analyzed the reading utterances of parent/child dyads with preschool aged child while reading informational and narrative books contributing to this line of research by systematically selecting books based on scholarly criteria to minimize variability within and between genres. I invited families whose children attended preschool at a private school to participate in this study. On a weekly basis, over a six week period, participating families selected an informational book and a narrative book to be read. Each newly selected book was read at least once during that week. Each reading was audio-taped and tapes were transcribed, coded, and analyzed. Results indicate that genre affects both the quality and quantity of parents' and children's reading utterances. Both parents and children generated more total utterances and comprehension related utterances when reading informational books than when reading narrative books. Two parents demonstrated a marked increase in their use of comprehension related utterances while reading informational books than when reading narrative books. Four of the six children demonstrated a marked increase in their use of comprehension related utterances while being read informational books compared to narrative books. I then conducted a more fine-grained analysis to examine the parents' and children's reading utterances while reading specific informational books and specific narrative books. Regardless of genre, the type of book being read affected the number of utterances generated by the parents and children differently. The children demonstrated a preference for narrative books over informational books. Finally, I found that three themes, supported with vignettes, emerged from the data: Lost Opportunities, Grasped Opportunities, and Influences on Reading Behaviors. All three emergent themes addressed parent/child interactions and the affect they had on the reading sessions

Time Allocations and Reward Structures for US Academic Economists from 1955–2005: Evidence from Three National Surveys

Using survey data collected in 1995, 2000 and 2005 from US academic economists, in which respondents were asked to indicate what percentage of their work time they allocate to research, teaching and service activities, and also how their departments and schools weight research, teaching and service in determining annual raises and making promotion and tenure decisions, we find these economists were allocating more time to teaching even though perceived departmental and school incentives provided a clear premium for research. The overall samples did not show major changes in their allocation of time from 1995–2005, but there were different responses at different types of schools, with increased time spent on research by faculty at doctoral schools while at masters' and baccalaureate schools more time was devoted to teaching. We use regression analysis to investigate factors that affect how different faculty members allocate their time between teaching and research. In addition to Carnegie school classifications and related school characteristics, faculty members' gender and rank were significant predictors of how economists allocate their time. Male economists, particularly among assistant professors at research universities, spent less time on teaching and more time on research than female economists.

Real radical initial ideals

We explore the consequences of an ideal I of real polynomials having a real radical initial ideal, both for the geometry of the real variety of I and as an application to sums of squares representations of polynomials. We show that if in_w(I) is real radical for a vector w in the tropical variety, then w is in the logarithmic set of the real variety. We also give algebraic sufficient conditions for w to be in the logarithmic limit set of a more general semialgebraic set. If in addition the entries of w are positive, then the corresponding quadratic module is stable. In particular, if in_w(I) is real radical for some positive vector w then the set of sums of squares modulo I is stable. This provides a method for checking the conditions for stability given by Powers and Scheiderer.Comment: 16 pages, added examples, minor revision

Who Teaches with More Than Chalk and Talk?

Probit analysis is used to investigate factors that affect instructors' choices of teaching methodologies in introductory economics. The results show that instructor gender, percent of work time devoted to teaching, and the school's Carnegie classification are important determinants. Also, although class size is not an important determinant in the choice of instructional techniques used in the classroom, it is important in the choice of print materials and out-of-class assignments.Economics; Introductory Economics

Evaluation of the Social Interaction Self-Statement Test with a Social Phobic Population

The convergent and discriminant validity of the Social Interaction Self-Statement Test (SISST) were evaluated in a sample of men and women awaiting treatment for fear and avoidance of social interactions. Partial correlations revealed that negative, but not positive, self-statement scores were generally related to self-report measures of anxiety and depression. Heart rate and subjective anxiety ratings derived from a behavioral simulation of a personally relevant anxiety-provoking situation were unrelated to SISST scores. However, subjects’ reports of negative thoughts obtained via the thought-listing procedure were related to the SISST negative self-statement scores, suggesting that the negative subscale of the SISST and the thought-listing procedure tap similar dimensions. Finally, the negative subscale of the SISST discriminated between social phobics whose primary fear involved social interactions and social phobics whose anxiety was confined to public-speaking situations. The findings support the use of the SISST with clinically socially anxious patients

DSM-III-R Subtypes of Social Phobia: Comparison of Generalized Social Phobics and Public Speaking Phobics

Social phobic patients who fear most or all social interaction situations are labeled generalized social phobics in DSM-III-R. Thirty-five patients who met this criterion were compared with 22 social phobic patients whose fears were restricted to public-speaking situations. Generalized social phobics were younger, less educated, and less likely to be employed, and their phobias were rated by clinical interviewers as more severe than those of public-speaking phobics. Generalized social phobics appeared more anxious and more depressed and expressed greater fears concerning negative social evaluation. They performed more poorly on individualized behavioral tests and differed from public-speaking phobics in their responses to cognitive assessment tasks. The two groups showed marked differences in their patterns of heart rate acceleration during the behavioral test. The implications of these findings for the classification and treatment of social phobic individuals are discussed

The definitive version was published in Aquaculture Environment Interactions 9 (2017): 331-346, doi:10.3354/aei00238.Tropical coral reefs are characterized by low-nutrient waters that support oligotrophic picoplankton over a productive benthic ecosystem. Nutrient-rich effluent released from aquaculture facilities into coral reef environments may potentially upset the balance of these ecosystems by altering picoplankton dynamics. In this study, we examined how effluent from a prawn (Litopenaeus vannamei) farming facility in Al Lith, Saudi Arabia, impacted the inorganic nutrients and prokaryotic picoplankton community in the waters overlying coral reefs in the Red Sea. Across 24 sites, ranging 0-21 km from the effluent point source, we measured nutrient concentrations, quantified microbial cell abundances, and sequenced bacterial and archaeal small subunit ribosomal RNA (SSU rRNA) genes to examine picoplankton phylogenetic diversity and community composition. Our results demonstrated that sites nearest to the outfall had increased concentrations of phosphate and ammonium and elevated abundances of non-pigmented picoplankton (generally heterotrophic bacteria). Shifts in the composition of the picoplankton community were observed with increasing distance from the effluent canal outfall. Waters within 500 m of the outfall harbored the most distinct picoplanktonic community and contained putative pathogens within the genus Francisella and order Rickettsiales. While our study suggests that at the time of sampling, the Al Lith aquaculture facility exhibited relatively minor influences on inorganic nutrients and microbial communities, studying the longer-term impacts of the aquaculture effluent on the organisms within the reef will be necessary in order to understand the full extent of the facility’s impact on the reef ecosystem.This research was supported by a Woods Hole Oceanographic Institution (WHOI) Ocean Life Institute postdoctoral scholar fellowship to A.A., the Semester at WHOI Program supporting C.B., and Award No. USA 00002 to K.H. made by King Abdullah University of Science and Technology (KAUST)

Hydrologic and Agricultural Earth Observations and Modeling for the Water-Food Nexus

In a globalizing and rapidly-developing world, reliable, sustainable access to water and food are inextricably linked to each other and basic human rights. Achieving security and sustainability in both requires recognition of these linkages, as well as continued innovations in both science and policy. We present case studies of how Earth observations are being used in applications at the nexus of water and food security: crop monitoring in support of G20 global market assessments, water stress early warning for USAID, soil moisture monitoring for USDA's Foreign Agricultural Service, and identifying food security vulnerabilities for climate change assessments for the UN and the UK international development agency. These case studies demonstrate that Earth observations are essential for providing the data and scalability to monitor relevant indicators across space and time, as well as understanding agriculture, the hydrological cycle, and the water-food nexus. The described projects follow the guidelines for co-developing useable knowledge for sustainable development policy. We show how working closely with stakeholders is essential for transforming NASA Earth observations into accurate, timely, and relevant information for water-food nexus decision support. We conclude with recommendations for continued efforts in using Earth observations for addressing the water-food nexus and the need to incorporate the role of energy for improved food and water security assessment

The definitive version was published in Proceedings of the Royal Society Open Science 5(12) (2018): 181358. doi: 10.1098/rsos.181358.The settlement of reef-building corals is critical to the survival and recovery of reefs. Recent evidence indicates that coral larvae orient towards reef sound, yet the components of the acoustic environment that may attract coral larvae and induce settlement are unknown. Here we investigated the effects of ambient soundscapes on settlement of Porites astreoides coral larvae using in situ chambers on reefs differing in habitat quality (coral and fish abundance). Mean larval settlement was twice as high in an acoustic environment with high levels of low-frequency sounds, typical of a high-quality, healthy reef; this result was observed in both natural light and dark treatments. Overall, the enhancement of coral settlement by soundscapes typical of healthy reefs suggests a positive feedback where soundscape properties of reefs with elevated coral and fish abundance may facilitate coral recruitment.This study is funded by NSF Biological Oceanography award 15-36782 which supported all authors
