Genetic characterization of chestnut (Castanea sativa Mill.) orchards and traditional nut varieties in El Bierzo, a glacial refuge and major cultivation site in Northwestern Spain

This paper presents a detailed genetic study of Castanea sativa in El Bierzo, a major nut production region with interesting features. It is located within a glacial refuge at one extreme of the distribution area (northwest Spain); it has a centenary tradition of chestnut management; and more importantly, it shows an unusual degree of genetic isolation. Seven nuclear microsatellite markers were selected to analyze the genetic variability and structure of 169 local trees grafted for nut production. We analyzed in the same manner 62 local nuts. The selected loci were highly discriminant for the genotypes studied, giving a combined probability of identity of 6.1 × 10−6. An unprecedented density of trees was sampled for this project over the entire region, and nuts were collected representing 18 cultivars marketed by local producers. Several instances of misclassification by local growers were detected. Fixation index estimates and analysis of molecular variance (AMOVA) data are supportive of an unexpectedly high level of genetic differentiation in El Bierzo, larger than that estimated in a previous study with broader geographical scope but based on limited local sampling (Pereira-Lorenzo et al., Tree Genet Genomes 6: 701–715, 2010a). Likewise, we have determined that clonality due to grafting had been previously overestimated. In line with these observations, no significant spatial structure was found using both a model-based Bayesian procedure and Mantel’s tests. Taken together, our results evidence the need for more fine-scale genetic studies if conservation strategies are to be efficiently improved.

Building resilience to water scarcity in Southern Spain: A case study of rice farming in Doñana protected wetlands

Agricultural water management needs to evolve in view of increased water scarcity, especially when farming and natural protected areas are closely linked. In the study site of Don?ana (southern Spain), water is shared by rice producers and a world heritage biodiversity ecosystem. Our aim is to contribute to defining adaptation strategies that may build resilience to increasing water scarcity and minimize water conflicts among agricultural and natural systems. The analytical framework links a participatory process with quantitative methods to prioritize the adaptation options. Bottom-up proposed adaptation measures are evaluated by a multi-criteria analysis (MCA) that includes both socioeconomic criteria and criteria of the ecosystem services affected by the adaptation options. Criteria weights are estimated by three different methods?analytic hierarchy process, Likert scale and equal weights?that are then compared. Finally, scores from an MCA are input into an optimization model used to determine the optimal land-use distribution in order to maximize utility and land-use diversification according to different scenarios of funds and water availability. While our results show a spectrum of perceptions of priorities among stakeholders, there is one overriding theme that is to define a way to restore part of the rice fields to natural wetlands. These results hold true under the current climate scenario and evenmore so under an increased water scarcity scenario.

Analysis of the suitability of existing medical ontologies for building a scalable semantic interoperability solution supporting multi-site collaboration in oncology

Semantic interoperability is essential to facilitate efficient collaboration in heterogeneous multi-site healthcare environments. The deployment of a semantic interoperability solution has the potential to enable a wide range of informatics supported applications in clinical care and research both within as ingle healthcare organization and in a network of organizations. At the same time, building and deploying a semantic interoperability solution may require significant effort to carryout data transformation and to harmonize the semantics of the information in the different systems. Our approach to semantic interoperability leverages existing healthcare standards and ontologies, focusing first on specific clinical domains and key applications, and gradually expanding the solution when needed. An important objective of this work is to create a semantic link between clinical research and care environments to enable applications such as streamlining the execution of multi-centric clinical trials, including the identification of eligible patients for the trials. This paper presents an analysis of the suitability of several widely-used medical ontologies in the clinical domain: SNOMED-CT, LOINC, MedDRA, to capture the semantics of the clinical trial eligibility criteria, of the clinical trial data (e.g., Clinical Report Forms), and of the corresponding patient record data that would enable the automatic identification of eligible patients. Next to the coverage provided by the ontologies we evaluate and compare the sizes of the sets of relevant concepts and their relative frequency to estimate the cost of data transformation, of building the necessary semantic mappings, and of extending the solution to new domains. This analysis shows that our approach is both feasible and scalable.

El recorrido: evaluación de las cualidades sensoriales y formales del medio urbano como parte de los criterios de caminabilidad. La ciudad de Taipei como caso de estudio

La presente investigación aborda el análisis de las cualidades del entorno urbano que inciden en la experiencia perceptiva de su recorrido. Los intereses que la motivan tienen que ver con la recuperación de la ciudad para el viandante y se sitúa dentro de un marco de intereses más amplio como es el de la ciudad sostenible. En primer lugar, se contextualiza el tema de la experiencia del recorrido a través de disciplinas diferentes como son el cine, la literatura, la arquitectura, el urbanismo, la arquitectura del paisaje, la psicología y la estética ambiental. De este modo, se refuerza el argumento en torno al papel que desempeñan la forma y otros estímulos sensoriales en la experiencia del espacio, ya sea éste urbano, arquitectónico o natural. La experiencia que las personas viven al desplazarse por un entorno viene definida por infinitos factores que van desde la configuración física del entorno recorrido, hasta el aprendizaje cultural de la persona que camina; desde los estímulos sensoriales que se reciben, hasta las condiciones físicas que posibilitan la funcionalidad del recorrido; desde las sutilezas de índole secuencial que se desvelan a medida que avanzamos, hasta las condiciones higrotérmicas en el momento en que se lleva a cabo el desplazamiento. Sin embargo, factores como las motivaciones y atenciones personales del que anda, así como sus recuerdos de experiencias anteriores, deseos, imaginación y estado de ánimo, también definen nuestra experiencia al caminar que, indudablemente, se encuentra ligada a nuestra personalidad y, por lo tanto, no puede ser exacta a la de otra persona. Conscientes de que todos estos factores se funden en un fenómeno global, y que no se dan en la vida por separado, nos hemos esforzado por independizar las cualidades sensoriales y formales, únicamente a efectos de investigación. La importancia del tema a investigar reside en las conexiones que existen entre las cualidades del medio construido y la experiencia cotidiana de su recorrido, en la medida en que dicha vinculación establece relaciones con la calidad de vida, la salud de los ciudadanos y sus sentimientos de identidad. En este sentido, el problema clave encontrado es que si la definición de la experiencia del recorrido urbano es demasiado amplia, se vuelve nebulosa e inoperativa, pero si se precisa demasiado, se pueden excluir variables importantes. Hemos concentrado nuestros esfuerzos en buscar un medio que permita hacer operativo el estudio de aspectos que, por su propia naturaleza, son difíciles de controlar y aplicar en la práctica. En este sentido, el campo de estudio que aúna interés en el tema, producción científica y vocación práctica, es el de la caminabilidad de las ciudades. Por esta razón, hemos situado nuestro trabajo dentro del marco de criterios que este campo establece para valorar un entorno caminable. Sin embargo, hemos detectado que los trabajos sobre caminabilidad tienden a desarrollarse dentro de la disciplina del planeamiento de transporte y, con frecuencia, siguiendo las mismas pautas que la investigación sobre el transporte motorizado. Además, la tendencia a proporcionar datos numéricos producto de la medición controlada de variables, para respaldar iniciativas dentro de los ámbitos de toma de decisiones, lleva consigo un progresivo alejamiento de los aspectos más sutiles y próximos de la experiencia de las personas y la especificidad de los lugares. Por estas razones, hemos estimado necesario profundizar en la experiencia peatonal explorando otras líneas de trabajo como son la habitabilidad de las ciudades, políticas llevadas a cabo para mejorar la calidad del espacio público o las certificaciones de sostenibilidad en el ámbito del urbanismo. También se han estudiado las aproximaciones gráficas a la representación y simulación de recorridos urbanos por su importancia en la comunicación y promoción de caminar. Para detectar las problemáticas implicadas en la definición de una herramienta que permita valorar, de manera operativa, la calidad de la experiencia del recorrido urbano, la metodología de valoración propuesta se ha basado en la combinación de distintos métodos y en la conjugación de tres aproximaciones: valoración por parte del investigador en calidad de experto, valoración realizada por el investigador en el papel de usuario y valoración por el ciudadano. El desarrollo de esta investigación se ha visto condicionado por la intención de aplicar lo estudiado en un caso práctico. El marco de criterios que los trabajos sobre caminabilidad de las ciudades establecen para que se dé un entorno caminable, se puede resumir en que concurran los siguientes factores: mezcla de usos, densidad de población y edificación relativamente altas, destinos públicos accesibles a pie, un alto grado de seguridad con respecto al tráfico y actos delictivos, alta funcionalidad (dimensiones, pendientes, etc.) y atractivo. Una vez definido el modelo de ciudad en que es pertinente realizar una investigación sobre las cualidades del entorno urbano responsables de que éste se perciba como atractivo, se escogió la ciudad de Taipei, entre otras razones, por cumplir con los requisitos restantes. Con respecto al caso práctico, el objetivo es detectar fortalezas y debilidades del área central de la ciudad de Taipei en cuanto a la experiencia perceptiva que proporciona a los viandantes. ABSTRACT This research addresses the analysis of the qualities of the urban environment that affect the perceptual experience of walking. The interests lying behind it are related to the recovery of the city for pedestrians, and is framed within the sustainable city framework of interests. Firstly, the issue of the experience of walking is contextualized through different disciplines such as film, literature, architecture, urban planning, landscape architecture, environmental psychology and aesthetics. This way, the argument about the role that form and other sensory stimuli play in the experience of space, whether it is urban, architectural or natural, is strengthened. The walking experience of people is defined by factors ranging from the physical configuration of the environment to the cultural background of the person who walks, from the sensory stimuli that are perceived to the physical conditions that enable the functionality of the walk, from the subtleties of sequential nature that are revealed as we move around to hygrothermal conditions at the specific time of walking. Nevertheless, factors such as personal motivations and attentions of the walker, as well as memories of past experiences, desires, imagination and mood, also define our walking experience that is undoubtedly linked to our personality and, therefore, it cannot be exactly the same as other people's experience. Being aware that all these factors come together in a total phenomenon and that, in real life, they do not exist separately, we focused on separating sensory and formal qualities only for research purposes. The importance of the research topic lies in the connections between the qualities of the built environment and the quotidian experience of walking through it, to the extent that such link establishes relationships with the quality of life, health and feelings of identity of citizens. In this sense, the key problem encountered is that, if the definition of urban walking experience is too broad, it becomes nebulous and non‐operational, but if it is too precise, important variables can be excluded. We concentrated our efforts on finding a way to operationalize the study of questions that, by their very nature, are difficult to control and apply in practice. In this regard, the field of study that combines interest in the topic, scientific production and practical purpose, is the walkability of cities. For this reason, we placed our work within the framework of the set of criteria that this field establishes for assessing an environment as walkable. However, we found that works on walkability tend to be developed within the discipline of transportation planning and often following the same guidelines that research on motorized transport. Furthermore, the tendency to provide numerical data as a result of the controlled measurement of variables in order to support initiatives in decision making areas, involves a progressive distancing from the proximity and the most subtle aspects of the experience of people, and from the specificity of places. For these reasons, we considered it was necessary to deepen into the study of pedestrians experience, by exploring other lines of work such as the livability of cities, implemented policies to improve the quality of the public space or sustainability certifications in urbanism. Graphic representation and simulation of urban walks are also studied due to their important role in communication and promotion of walking. In order to find the issues involved in defining a tool to assess, in an operational way, the quality of urban walking experience, the proposed assessment methodology is based on the combination of different methods and the synthesis of three approaches: assessment by the researcher as expert, assessment by the researcher playing the role of user and assessment by the citizens. The development of this research has been conditioned by our intention of applying it in a case study. The framework of criteria that works on walkability of cities set to define a walkable environment, can be summarized in the following factors: mix of uses, population and building density rather high, public destinations accessible on foot, high levels of safety in terms of traffic and crime, high functionality (dimensions, slopes, etc.) and attractiveness. After defining the model of city in which it is relevant to conduct an investigation on the qualities that are responsible of the attractiveness of the environment; Taipei City was selected because it meets the remaining requirements, among other reasons. Regarding the case study, the goal is to identify strengths and weaknesses in the central area of Taipei City in terms of the perceptual experience of pedestrians.

Changes in the governance system for higher education in Peru to meet the challenges of the 21st century

The competition in markets, the distribution of limited resources based on productivity and performance, and the efficient management of universities are changing the criteria of trust and legitimacy of the educational system in Peru. Universities are perceived more as institutions of the public sector, while the services they offer must rather contribute to the modernization of the emerging society and the knowledge economy. Higher Educations reforms - initiated in the 1980s - have been inspired by the successful university organizations that have managed to change their governance and addressed to transform certain bureaucratic institutions into organizations capable of playing active role in this global competition for resources and best talent. Within this context, Peruvian universities are facing two major challenges: adapting themselves to new global perspectives and being able to develop a better response to society demands, needs and expectations. This article proposes a model of governance system for higher education in Peru that gives a comprehensive solution to these challenges, allowing dealing with the problems of universities for their development and inclusion within the global trends. For this purpose, a holistic and qualitative methodologic approach was developed, considering an integrated method which considered educational reality as a whole, understanding its facts, components and elements that affects its outcomes. It is proposed to define a policy for university education in Peru that permeates society, by changing the planning model from a social reform model to a policy analysis model, where the Peruvian State acts as sole responsible for responding to the demanding society as its legal representative complemented with some external and independent bodies that define the basis of best practice, as it is being done in many university models worldwide.

Ol-Prx 3, a member of an additional class of homeobox genes, is unimodally expressed in several domains of the developing and adult central nervous system of the medaka (Oryzias latipes)

Large-scale genetic screens for mutations affecting early neurogenesis of vertebrates have recently been performed with an aquarium fish, the zebrafish. Later stages of neural morphogenesis have attracted less attention in small fish species, partly because of the lack of molecular markers of developing structures that may facilitate the detection of discrete structural alterations. In this context, we report the characterization of Ol-Prx 3 (Oryzias latipes-Prx 3). This gene was isolated in the course of a large-scale screen for brain cDNAs containing a highly conserved DNA binding region, the homeobox helix-three. Sequence analysis revealed that this gene belongs to another class of homeobox genes, together with a previously isolated mouse ortholog, called OG-12 [Rovescalli, A. C., Asoh, S. & Nirenberg, M. (1996) Proc. Natl. Acad. Sci. USA 93, 10691–10696] and with the human SHOX gene [Rao, E., Weiss, B., Fukami, M., Rump, A., Niesler, B., et al. (1997) Nat. Genet. 16, 54–62], thought to be involved in the short-stature phenotype of Turner syndrome patients. These three genes exhibit a moderate level of identity in the homeobox with the other genes of the paired-related (PRX) gene family. Ol-Prx 3, as well as the PRX genes, are expressed in various cartilaginous structures of head and limbs. These genes might thus be involved in common regulatory pathways during the morphogenesis of these structures. Moreover, this paper reports a complex and monophasic pattern of Ol-Prx 3 expression in the central nervous system, which differs markedly from the patterns reported for the PRX genes, Prx 3 excluded: this gene begins to be expressed in a variety of central nervous system territories at late neurula stage. Strikingly, it remains turned on in some of the derivatives of each territory during the entire life of the fish. We hope this work will thus help identify common features for the PRX 3 family of homeobox genes.

Glucose-induced Autophagy of Peroxisomes in Pichia pastoris Requires a Unique E1-like Protein

Cytosolic and peroxisomal enzymes necessary for methanol assimilation are synthesized when Pichia pastoris is grown in methanol. Upon adaptation from methanol to a glucose environment, these enzymes are rapidly and selectively sequestered and degraded within the yeast vacuole. Sequestration begins when the vacuole changes shape and surrounds the peroxisomes. The opposing membranes then fuse, engulfing the peroxisome. In this study, we have characterized a mutant cell line (glucose-induced selective autophagy), gsa7, which is defective in glucose-induced selective autophagy of peroxisomes, and have identified the GSA7 gene. Upon glucose adaptation, gsa7 cells were unable to degrade peroxisomal alcohol oxidase. We observed that the peroxisomes were surrounded by the vacuole, but complete uptake into the vacuole did not occur. Therefore, we propose that GSA7 is not required for initiation of autophagy but is required for bringing the opposing vacuolar membranes together for homotypic fusion, thereby completing peroxisome sequestration. By sequencing the genomic DNA fragment that complemented the gsa7 phenotype, we have found that GSA7 encodes a protein of 71 kDa (Gsa7p) with limited sequence homology to a family of ubiquitin-activating enzymes, E1. The knockout mutant gsa7Δ had an identical phenotype to gsa7, and both mutants were rescued by an epitope-tagged Gsa7p (Gsa7-hemagglutinin [HA]). In addition, a GSA7 homolog, APG7, a protein required for autophagy in Saccharomyces cerevisiae, was capable of rescuing gsa7. We have sequenced the human homolog of GSA7 and have shown many regions of identity between the yeast and human proteins. Two of these regions align to the putative ATP-binding domain and catalytic site of the family of ubiquitin activating enzymes, E1 (UBA1, UBA2, and UBA3). When either of these sites was mutated, the resulting mutants [Gsa7(ΔATP)-HA and Gsa7(C518S)-HA] were unable to rescue gsa7 cells. We provide evidence to suggest that Gsa7-HA formed a thio-ester linkage with a 25–30 kDa protein. This conjugate was not observed in cells expressing Gsa7(ΔATP)-HA or in cells expressing Gsa7(C518S)-HA. Our results suggest that this unique E1-like enzyme is required for homotypic membrane fusion, a late event in the sequestration of peroxisomes by the vacuole.

Human aspartic protease memapsin 2 cleaves the β-secretase site of β-amyloid precursor protein

The cDNAs of two new human membrane-associated aspartic proteases, memapsin 1 and memapsin 2, have been cloned and sequenced. The deduced amino acid sequences show that each contains the typical pre, pro, and aspartic protease regions, but each also has a C-terminal extension of over 80 residues, which includes a single transmembrane domain and a C-terminal cytosolic domain. Memapsin 2 mRNA is abundant in human brain. The protease domain of memapsin 2 cDNA was expressed in Escherichia coli and was purified. Recombinant memapsin 2 specifically hydrolyzed peptides derived from the β-secretase site of both the wild-type and Swedish mutant β-amyloid precursor protein (APP) with over 60-fold increase of catalytic efficiency for the latter. Expression of APP and memapsin 2 in HeLa cells showed that memapsin 2 cleaved the β-secretase site of APP intracellularly. These and other results suggest that memapsin 2 fits all of the criteria of β-secretase, which catalyzes the rate-limiting step of the in vivo production of the β-amyloid (Aβ) peptide leading to the progression of Alzheimer's disease. Recombinant memapsin 2 also cleaved a peptide derived from the processing site of presenilin 1, albeit with poor kinetic efficiency. Alignment of cleavage site sequences of peptides indicates that the specificity of memapsin 2 resides mainly at the S1′ subsite, which prefers small side chains such as Ala, Ser, and Asp.

Identification of bdm-1, a gene involved in G protein β-subunit function and α-subunit accumulation

Targeted disruption of Gα and Gβ genes has established the requirement of an intact G protein signaling pathway for optimal execution of several important physiological processes, including pathogenesis, in the chestnut blight fungus Cryphonectria parasitica. We now report the identification of a G protein signal transduction component, beta disruption mimic factor-1, BDM-1. Disruption of the corresponding gene, bdm-1, resulted in a phenotype indistinguishable from that previously observed after disruption of the Gβ subunit gene, cpgb-1. The BDM-1 deduced amino acid sequence contained several significant clusters of identity with mammalian phosducin, including a domain corresponding to a highly conserved 11-amino acid stretch that has been implicated in binding to the Gβγ dimer and two regions of defined Gβ/phosducin contact points. Unlike the negative regulatory function proposed for mammalian phosducin, the genetic data presented in this report suggest that BDM-1 is required for or facilitates Gβ function. Moreover, disruption of either bdm-1 or cpgb-1 resulted in a significant, posttranscriptional reduction in the accumulation of CPG-1, a key Gα subunit required for a range of vital physiological processes.

Selective binding of perfringolysin O derivative to cholesterol-rich membrane microdomains (rafts)

There is increasing evidence that sphingolipid- and cholesterol-rich microdomains (rafts) exist in the plasma membrane. Specific proteins assemble in these membrane domains and play a role in signal transduction and many other cellular events. Cholesterol depletion causes disassembly of the raft-associated proteins, suggesting an essential role of cholesterol in the structural maintenance and function of rafts. However, no tool has been available for the detection and monitoring of raft cholesterol in living cells. Here we show that a protease-nicked and biotinylated derivative (BCθ) of perfringolysin O (θ-toxin) binds selectively to cholesterol-rich microdomains of intact cells, the domains that fulfill the criteria of rafts. We fractionated the homogenates of nontreated and Triton X-100-treated platelets after incubation with BCθ on a sucrose gradient. BCθ was predominantly localized in the floating low-density fractions (FLDF) where cholesterol, sphingomyelin, and Src family kinases are enriched. Immunoelectron microscopy demonstrated that BCθ binds to a subpopulation of vesicles in FLDF. Depletion of 35% cholesterol from platelets with cyclodextrin, which accompanied 76% reduction in cholesterol from FLDF, almost completely abolished BCθ binding to FLDF. The staining patterns of BCθ and filipin in human epidermoid carcinoma A431 cells with and without cholesterol depletion suggest that BCθ binds to specific membrane domains on the cell surface, whereas filipin binding is indiscriminate to cell cholesterol. Furthermore, BCθ binding does not cause any damage to cell membranes, indicating that BCθ is a useful probe for the detection of membrane rafts in living cells.

Ferulate-5-hydroxylase from Arabidopsis thaliana defines a new family of cytochrome P450-dependent monooxygenases.

The fah1 mutant of Arabidopsis is defective in the accumulation of sinapic acid-derived metabolites, including the guaiacyl-syringyl lignin typical of angiosperms. Earlier results indicated that the FAH1 locus encodes ferulate-5-hydroxylase (F5H), a cytochrome P450-dependent monooxygenase (P450) of the general phenylpropanoid pathway. We have cloned the gene encoding this P450 by T-DNA tagging and have confirmed the identity of the cloned gene by complementation of the mutant phenotype. F5H shows 34% amino acid sequence identity with the avocado ripening-induced P450 CYP71A1 and 32% identity with the flavonoid-3',5'-hydroxylases of Petunia hybrida. In contrast, it shares much less homology with cinnamate-4-hydroxylase, a P450 that catalyzes the hydroxylation of cinnamic acid three steps earlier in the general phenylpropanoid pathway. Since the highest degree of identity between F5H and previously sequenced P450s is only 34%, F5H identifies a new P450 subfamily that has been designated CYP84.

The Vernacular Discourse of the "Arab Spring:" An Analysis of the Visual, the Embodied, and the Textual Rhetorics of the Karama Revolution

The Vernacular Discourse of the "Arab Spring" is a project that bridges the divide between the East and the West by offering new readings to Arab subjectivities. Through an analysis of the "Arab Spring" through the lens of vernacular discourse, it challenges the Euro-Americo-centric legacies of Orientalism in Western academia and the new wave of extremism in the Arab world by offering alternative representations of Arab bodies and subjectivities. To offer this new reading of the "Arab Spring," it explores the foundations of critical rhetoric as a theory and a practice and argues for a turn towards a critical vernacular discourse. The turn towards critical vernacular discourse is important as it urges the analyses of different artifacts produced by marginalized groups in order to understand their perspectives that have largely been foreclosed in traditional cultural studies research. Building on embodied/performative critical rhetoric, the vernacular discourses of the Arab revolutionary body examines other forms of knowledge productions that are not merely textual; more specifically, through data gathered in the Lhbib Bourguiba, Tunisia. This analysis of the political revolutionary body unveils the complexity underlining the discussion around issues of identity, agency and representation in the Middle East and North Africa, and calls for a critical study towards these issues in the region beyond the binary approach that has been practiced and applied by academics and media analysts. Hence, by analyzing vernacular discourse, this research locates a method of examining and theorizing the dialectic between agency, citizenry, and subjectivity through the study of how power structure is recreated and challenged through the use of the vernacular in revolutionary movements, as well as how marginalized groups construct their own subjectivities through the use of vernacular discourse. Therefore, highlighting the political prominence of evaluating the Arab Spring as a vernacular discourse is important in creating new ways of understanding communication in postcolonial/neocolonial settings.

The Importance of the First Psychotherapy Case in the Development of the Therapist's Professional Self as Viewed Through the Lens of Self Psychology

This paper explores the gap in the literature between what is herein referred to as the "first psychotherapy case" and its impact on the development of the trainee psychotherapist's professional self. The self psychology concepts of identity development, selfobject needs and fulfillment, narcissism, shame, countertransference, and structuralization are incorporated into the theoretical framework from which this developmental milestone is viewed. The theory's emphasis on early experiences and the development of self highlight the distinctiveness of the first case for the therapist. The beginning psychotherapy case poses a unique context for selfobject experiences and the developing self, involving both the therapist's presumably mature needs (assuming an existing cohesive nuclear self) and more infantile needs as the professional, peripheral self develops. As a result, the potential and important implications for the psychotherapist, the patient, training implications for the supervisor, and the ensuing treatment through termination are identified. The intent is to shed light on an area that is understudied thus far, and to begin a conversation as to why and how the impact of the first case on the psychotherapist should be examined. Implications, limitations, and ideas for future exploratory and qualitative research are also discussed.

BigLaw Identity Capital: Pink and Blue, Black and White

This Article advances a new capital framework for understanding the bargain between large law firms and their lawyers, depicting BigLaw relationships not as basic labor-salary exchanges but rather as complex transactions in which large law firms and their lawyers exchange labor and various forms of capital — social, cultural, and identity. First, it builds on the work of Pierre Bourdieu regarding economic, cultural, symbolic, and social capital by examining the concepts of positive and negative capital, exploring the meaning of capital ownership by entities, and developing the notion of identity capital — the value individuals and institutions derive from their identities. Then, the Article advances a capital theory of BigLaw, in which large law firms and their lawyers engage in complex transactions trading labor, social, cultural, and identity capital for economic, social, cultural, and identity capital. Capital analysis sheds new light on the well-documented and troubling underrepresentation of diverse lawyers at BigLaw. It shows that the underrepresentation of women and minority lawyers is not solely the result of exogenous forces outside the control of large law firms such as implicit bias, but rather the outcome of the very exchanges in which BigLaw and its lawyers engage. Specifically, large law firms take into account the capital endowments of their lawyers in making hiring, retention and promotion decisions, and derive value from their lawyers’ capital, for example, by trading on the identity of women and minority lawyers in marketing themselves as being diverse and inclusive to clients and potential recruits. Yet, while BigLaw trades for the identity capital of women and minority lawyers, it fails to offer them opportunities in return to acquire the social and cultural capital necessary for attaining positions of power, resulting in underrepresentation. Moreover, these labor-capital exchanges are often implicit and made by uninformed participants, and therefore unjust. Exactly because the capital framework describes the underrepresentation of diverse lawyers at BigLaw as an endogenous outcome within the control of BigLaw and its lawyers, however, it is a cautiously optimistic model that offers hope for greater representation of diverse lawyers in positions of power and influence. The Article suggests policies and procedures BigLaw can and should adopt to improve the quality of the exchanges it offers to women and minority attorneys and to reduce the underrepresentation of diverse lawyers within its ranks. Employing the concepts of capital transparency, capital boundary, and capital infrastructure, it demonstrates how BigLaw can (1) explicitly recognize the roles social, cultural, and identity capital play in its hiring, retention and promotion apparatuses and (2) revise its policies and procedures to ensure that all of its lawyers have equal opportunities to develop the requisite capital and compete on equal and fair terms for positions of power and influence.

Identity Entrepreneurs

In my previous article Racial Capitalism, I examined the ways in which white individuals and predominantly white institutions derive value from non-white racial identity. This process flows from our intense social and legal preoccupation with diversity. And it results in the commodification of non-white racial identity, with negative implications for both individuals and society. This Article picks up where Racial Capitalism left off in three ways. As a foundation, it first expands the concept of racial capitalism to identity categories more generally, explaining that individual in-group members and predominantly in-group institutions — usually individuals or institutions that are white, male, straight, wealthy, and so on — can and do derive value from out-group identities. Second, the Article turns from the overarching system of identity capitalism to the myriad ways that individual out-group members actively participate in that system. In particular, I examine how out-group members leverage their out-group status to derive social and economic value for themselves. I call such out-group participants identity entrepreneurs. Identity entrepreneurship is neither inherently good nor inherently bad. Rather, it is a complicated phenomenon with both positive and negative consequences. Finally, the Article considers the appropriate response to identity entrepreneurship. We should design laws and policies to maximize both individual agency and access to information for out-group members. Such reforms would protect individual choice while making clear the consequences of identity entrepreneurship both for individual identity entrepreneurs and for the out-group as a whole. A range of legal doctrines interact with and influence identity entrepreneurship, including employment discrimination under Title VII, rights of privacy and publicity, and intellectual property. Modifying these doctrines to take account of identity entrepreneurship will further progress toward an egalitarian society in which in-group and out-group identities are valued equally.
