The recent history of Sherpas demonstrates how identities can be scarce goods. While ‘Sherpa’ refers to an ethnic identity, ‘Sherpa’ refers to a crucial occupation in the trekking industry.i Their privileged position in Nepal’s international tourist industry is related to their common reputation. Their collective use of identity seems to help them getting access to an economic niche, and work in tourism seems to be an aspect of being Sherpa. Thus, an individual that operates in the tourist market does not only manage material assets but also identity assets to maintain the Sherpa reputation. Consequently, one can expect it to be a collective concern to husband their image, ie to control each member’s behaviour which could affect the Sherpa image. This article on Sherpa identity in encounters with outsiders analyses Sherpaness as a manageable resource that constitutes a collectively sanctioned commons. My point of departure is Barth’s analysis of ethnic boundary dynamics (1969, 1994) combined with Bourdieu’s concept of ‘capital’ and Hardin’s perspective on commons.DOI: 10.3126/dsaj.v1i0.288Dhaulagiri Vol.1 (2005) pp.176-192

Abstract Checkpoint gene function prevents meiotic progression when recombination is blocked by mutations in the recA homologue DMC1. Bypass of dmc1 arrest by mutation of the DNA damage checkpoint genes MEC1, RAD17, or RAD24 results in a dramatic loss of spore viability, suggesting that these genes play an important role in monitoring the progression of recombination. We show here that the role of mitotic checkpoint genes in meiosis is not limited to maintaining arrest in abnormal meioses; mec1-1, rad24, and rad17 single mutants have additional meiotic defects. All three mutants display Zip1 polycomplexes in two- to threefold more nuclei than observed in wild-type controls, suggesting that synapsis may be aberrant. Additionally, all three mutants exhibit elevated levels of ectopic recombination in a novel physical assay. rad17 mutants also alter the fraction of recombination events that are accompanied by an exchange of flanking markers. Crossovers are associated with up to 90% of recombination events for one pair of alleles in rad17, as compared with 65% in wild type. Meiotic progression is not required to allow ectopic recombination in rad17 mutants, as it still occurs at elevated levels in ndt80 mutants that arrest in prophase regardless of checkpoint signaling. These observations support the suggestion that MEC1, RAD17, and RAD24, in addition to their proposed monitoring function, act to promote normal meiotic recombination.

Collaboration plays a critical role in fostering innovation and value creation in the aviation sector. However, how factors and connections relate to the achievement of innovative outcomes in aviation require further investigation. This study investigates the key factors that create a conceptual framework by conducting a literature review and an archival analysis of news articles. The model proposed involves factors such as strategic decision-making; networking and partner choice; cultural context, values, behaviour and compatibilities; collaboration configuration; issues and risks shared; skills, capacities and experience; infrastructure and resources available; engagement activities; knowledge transfer, absorption and appropriation; collaboration management; communication flows; external environment and demand; and expectations and outcomes. Promising collaborations are also indicated in areas where the framework could be adopted to increase partnerships and outcomes. Also, we highlight best practice examples from leading organizations, such as International Airlines Group (IAG), Emirates Airline, Singapore Airlines, Boeing and JetBlue, to provide insights into existing collaborations that have led to innovation and value creation in this sector.

Abstract We study conformal boundary conditions for the theory of a single real scalar to investigate whether the known Dirichlet and Neumann conditions are the only possibilities. For this free bulk theory there are strong restrictions on the possible boundary dynamics. In particular, we find that the bulk-to-boundary operator expansion of the bulk field involves at most a ‘shadow pair’ of boundary fields, irrespective of the conformal boundary condition. We numerically analyze the four-point crossing equations for this shadow pair in the case of a three-dimensional boundary (so a four-dimensional scalar field) and find that large ranges of parameter space are excluded. However a ‘kink’ in the numerical bounds obeys all our consistency checks and might be an indication of a new conformal boundary condition.

Abstract We compute the deficiency spaces of operators of the form $H_A{\hat {\otimes }} I + I{\hat {\otimes }} H_B$ , for symmetric $H_A$ and self-adjoint $H_B$ . This enables us to construct self-adjoint extensions (if they exist) by means of von Neumann's theory. The structure of the deficiency spaces for this case was asserted already in Ibort et al. [Boundary dynamics driven entanglement, J. Phys. A: Math. Theor.47(38) (2014) 385301], but only proven under the restriction of $H_B$ having discrete, non-degenerate spectrum.
