Soil And Water

Excessive boron (B) in soil and water is a problem for pistachio (Pistacia vera L.) production in the San Joaquin Valley (SJV) of California. Although amenable, leaching of B requires more water than chlorine (Cl) or sodium (Na) and is increasingly difficult as B in irrigation water increases. The lack of subsurface drainage to the ocean increases soil salinity in many growing areas, especially on the west side of the SJV where B is often excessive natively in the soil and water. Pistachio rootstocks that can tolerate or exclude B may be a partial solution. For the past decade in California, the dominant rootstock has been seedlings and clonal selections of University of California Berkeley 1 (UCB-1), which is a hybrid of P. atlantica × P. integerrima. This reliance on a genetically similar pool of rootstocks has constrained Pistacia’s genetic potential for adapting to high-salt environments. This study compared scion and rootstock leaflet B concentration of novel hybrid experimental rootstocks with variable percentages of P. vera and P. integerrima heritage with UCB-1. Rootstocks with P. vera heritage limited B in both rootstock and scion leaflets compared with UCB-1. In six trials conducted over several years, leaflet B in ungrafted hybrid rootstocks having 62.5% to 75% P. vera and 25% to 37.5% P. integerrima heritage had 27.6% to 43.1% lower B leaflet concentration than did UCB-1. Depending on the experiment and year, grafted rootstocks having 37.5% P. vera and 62.5% P. integerrima heritage had 46.8% to 70.8% lower B scion leaflet concentration than did UCB-1. Genetic variation in B uptake in Pistacia species and interspecific hybrids, and among individual seedlings within populations, allows the breeding of pistachio rootstocks more tolerant of excess B.

The University

Richard J. K. Taylor of the University of York employed (Tetrahedron Lett. 2011, 52, 2024) the Jørgensen protocol to add 2 to 1, to give the enantiomerically enriched cyclohexenone 3. Condensation of 3 with aqueous ammonia led directly to (-)-mearsine 4. Wei-Dong Z. Li of Nankai University found (Org. Lett. 2011, 13, 3538) that the intermediate from Dibal reduction of the lactone 5 underwent Nazarov cyclization, giving the α-hydroxy cyclopentenone 6. After acetylation, deprotection gave an amine that cyclized with high diastereocontrol, leading to (±)-cephalotaxine 7. Tony K. M. Shing of the Chinese University of Hong Kong cyclized (Org. Lett. 2011, 13, 2916) the aldehyde 8 by exposure to 9. The product 10 was carried on to (-)-cocaine 11, as well as several hydroxylated cocaine derivatives. Susumi Hatakeyama of Nagasaki University found (Tetrahedron Lett. 2011, 52, 923) that exposure of the simple prochiral aldehyde 12 to catalytic proline transformed it, after reduction, into the cyclized diol 13 in high ee. The diol 13 was readily carried on to quinine 14. M.-Lluïsa Bennasar of the University of Barcelona devised (Org. Lett. 2011, 13, 2042) Pd-catalyzed conditions for the cyclization of 15 that selectively delivered the unstable kinetic product 18. Selective hydrogenation of the more reactive bridgehead alkene then led to cleavamine 17. The alkene 16 is also prochiral, so it is possible that a catalyst could be found that would deliver 17 in high ee. The synthesis of the heptacyclic alkaloid strychnine 23 would, in the past, have been a major undertaking. Christopher D. Vanderwal of the University of California, Irvine, prepared (Chem. Sci. 2011, 2, 649) 23 in just six linear steps. The dienyl aldehyde 18 was available in two steps from tryptophyl bromide. Exposure to t -BuOK cyclized 18 to 19. N-deallylation followed by alkylation with 20 provided 21, setting the stage for a truly spectacular Brook rearrangement/conjugate addition, to give the Wieland-Gumlich aldehyde 22. The known condensation with malonic acid completed the preparation of 23.

Behavioural economics is a research agenda, which gradually has moved from the periphery to the centre of the discipline of economics. The rise of behavioural economics has fostered a burgeoning number of studies dealing with the past, present and future of the field. In contrast to these studies which focus on predestinated scholars, outlets and key concepts, this article uses exploratory bibliometric approaches to map behavioural economics. Utilising a novel data set, comprising 104,558 references across 1,872 articles published in the period 1956–2016, the article systematically illuminates the historical foundations, development and interdisciplinary nature of behavioural economics. The article shows (a) the overlooked role of several behavioural psychologists in shaping the field; (b) the influence of the Anglo-Saxon universities, such as University of California Berkeley, Harvard University and University of Pennsylvania; and that (c) behavioural economics mainly draws knowledge from five disciplinary clusters: (a) economics and policy, (b) psychology, (c) pharmacology, (d) health and (e) law.

The Grotesque

In this article Richard Hornby argues that Ibsen's plays are badly performed today, or not performed at all, because of directors' refusal to take them with appropriate seriousness. The tendency is to stage the plays' reputation as simplistic social problem plays rather than as the complex, challenging, bizarre dramas that Ibsen actually wrote. In particular, directors avoid the grotesque elements that are the true ‘quintessence of Ibsenism’, and that are often remarkably similar in style to that of avant-garde playwrights today. Richard Hornby is Emeritus Professor of Theatre at the University of California, Riverside. For the past twenty-eight years he has been theatre critic for The Hudson Review, and is author of six books and over two hundred published articles on various aspects of theatre. This essay was delivered as the keynote address at the fourteenth annual Ibsen Festival of the Commonweal Theatre Company, Lanesboro, Minnesota, in April 2011.

Geobiologist Dawn Sumner, known for her research on early life in Antarctica, her contributions to the Mars Curiosity science team, and for co-founding KeckCAVES at the University of California Davis, has also spent the past decade working in collaboration with artists. This paper addresses the relevance of these art/science collaborations to her scientific practice through an analysis of four of her projects: Collapse (suddenly falling down) with Sideshow Physical Theater; Dream Vortex with Meredith Tromble; Life Extreme with Philip Alden Benn; and The Vortex with Donna Sternberg and Meredith Tromble. The experiences gained by Sumner and her collaborators show that there are many different ways in which artists and scientists can learn from each other. Echoing throughout the collaborations is the realisation that turning ideas into form yields a result that can stimulate the next cycle of creativity.

In this article, we present our teen leadership group and projects. We describe our “I’m a Student, Too!” campaign and why it is important to raise awareness about Latino/a children and families that live in Isla Vista, California, which has the reputation of being a college town. We outline our group’s mandate to create a better, safer, and healthier place where youth and families can grow up. We then describe how we collected data on people’s opinions of Isla Vista over the past two years and how we shared this information at town halls, University of California Santa Barbara orientations, and community conferences to make positive changes in our community.
