Deciphering Consumer Commitment: Exploring the Dual Influence of Self-Brand and Self-Group Relationships
Consumer-brand relationships are highly valued as brand-committed consumers are thought to deliver many positive outcomes for affiliated brands. However, in addition to connections between individuals and brands, consumer-brand relationships also involve relationships between individuals and other brand users. Little attention has been given to the potential consequences associated with commitment to other brand users as compared to the brand itself. Therefore, our framework establishes two distinct types of consumer-brand relationships (i.e., self-brand relationships vs. self-group relationships) that differentially influence brand commitment versus group commitment, leading to contrasting effects on both desirable and undesirable brand outcomes. Specifically, our studies illuminate that while brand commitment is largely associated with favorable brand-related outcomes, group commitment does not protect against brand switching and is negatively related to willingness to pay price premiums and positive word-of-mouth. Our main contribution is uncovering how consumer-brand relationships face tradeoffs between brand and group attachments, whereby commitment provides both conditional benefits as well as unintended consequences

Manacled to Identity: Cosmopolitanism, Class, and âThe Culture Conceptâ in Stephen Crane
This article begins with a close reading of Stephen Craneâs short story âManacledâ from 1900, which situates this rarely considered short work within the context of contemporary debates about realism. I then proceed to argue that many of the debates raised by the tale have an afterlife in our own era of American literary studies, which has frequently focused on questions of âidentityâ and âcultureâ in its reading of realism and naturalism to the exclusion of the importance of cosmopolitan discourses of diffusion and exchange across national borders. I then offer a brief reading of Craneâs novel Georgeâs Mother, which follows Walter Benn Michaels in suggesting that the recent critical attention paid to particularities of cultural difference in American studies have come to conflate ideas of class and social position with ideas of culture in ways that have ultimately obscured the presence of genuine historical inequalities in US society. In order to challenge this critical commonplace, I situate Craneâs work within a history of transatlantic cosmopolitanism associated with the ideas of Franz Boas and Matthew Arnold to demonstrate the ways in which Craneâs narratives sought out an experience of the universal within their treatments of the particular
Water advance model and sensor system can reduce tail runoff in irrigated alfalfa fields
Surface irrigation, such as flood or furrow, is the predominant form of irrigation
in California for agronomic crops. Compared to other irrigation methods, however,
it is inefficient in terms of water use; large quantities of water, instead of being
used for crop production, are lost to excess deep percolation and tail runoff. In
surface-irrigated fields, irrigators commonly cut off the inflow of water when the
water advance reaches a familiar or convenient location downfield, but this experience-based
strategy has not been very successful in reducing the tail runoff water. Our study
compared conventional cutoff practices to a retroactively applied model-based cutoff
method in four commercially producing alfalfa fields in Northern California, and evaluated
the model using a simple sensor system for practical application in typical alfalfa
fields. These field tests illustrated that the model can be used to reduce tail runoff
in typical surface-irrigated fields, and using it with a wireless sensor system saves
time and labor as well as water
Proton Beam Therapy Versus Conformal Photon Radiation Therapy for Childhood Craniopharyngioma: Multi-institutional Analysis of Outcomes, Cyst Dynamics, and Toxicity
PurposeWe compared proton beam therapy (PBT) with intensity modulated radiation therapy (IMRT) for pediatric craniopharyngioma in terms of disease control, cyst dynamics, and toxicity.Methods and MaterialsWe reviewed records from 52 children treated with PBT (n=21) or IMRT (n=31) at 2 institutions from 1996-2012. Endpoints were overall survival (OS), disease control, cyst dynamics, and toxicity.ResultsAt 59.6 months' median follow-up (PBT 33 mo vs IMRT 106 mo; P<.001), the 3-year outcomes were 96% for OS, 95% for nodular failure-free survival and 76% for cystic failure-free survival. Neither OS nor disease control differed between treatment groups (OS P=.742; nodular failure-free survival P=.546; cystic failure-free survival P=.994). During therapy, 40% of patients had cyst growth (20% requiring intervention); immediately after therapy, 17 patients (33%) had cyst growth (transient in 14), more commonly in the IMRT group (42% vs 19% PBT; P=.082); and 27% experienced late cyst growth (32% IMRT, 19% PBT; P=.353), with intervention required in 40%. Toxicity did not differ between groups. On multivariate analysis, cyst growth was related to visual and hypothalamic toxicity (P=.009 and .04, respectively). Patients given radiation as salvage therapy (for recurrence) rather than adjuvant therapy had higher rates of visual and endocrine (P=.017 and .024, respectively) dysfunction.ConclusionsSurvival and disease-control outcomes were equivalent for PBT and IMRT. Cyst growth is common, unpredictable, and should be followed during and after therapy, because it contributes to late toxicity. Delaying radiation therapy until recurrence may result in worse visual and endocrine function
The VMC ESO Public Survey
The VISTA near-infrared YJKs survey of the Magellanic Clouds system (VMC) has entered its core phase: about 50% of the observations across the Large and Small Magellanic Clouds (LMC, SMC), the Magellanic Bridge and Stream have already been secured and the data are processed and analysed regularly. The initial analyses, concentrated on the first two completed tiles in the LMC (including 30 Doradus and the South Ecliptic Pole), show the superior quality of the data. The photometric depth of the VMC survey allows the derivation of the star formation history (SFH) with unprecedented quality compared to previous wide-area surveys, while reddening maps of high angular resolution are constructed using red clump stars. The multi-epoch Ks-band data reveal tight period-luminosity relations for variable stars and permit the measurement of accurate proper motions of the stellar populations. The VMC survey continues to acquire data that will address many issues in the field of star and galaxy evolution
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficiently to enable an affordable space-based telescope mission capable of discovering and characterizing Earthlike planets orbiting nearby bright sunlike stars in order to search for signs of habitability and biosignatures. Such a mission can also be equipped with instrumentation that will enable broad and exciting general astrophysics and planetary science not possible from current or planned facilities. HabEx is a space telescope with unique imaging and multi-object spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR. These capabilities allow for a broad suite of compelling science that cuts across the entire NASA astrophysics portfolio. HabEx has three primary science goals: (1) Seek out nearby worlds and explore their habitability; (2) Map out nearby planetary systems and understand the diversity of the worlds they contain; (3) Enable new explorations of astrophysical systems from our own solar system to external galaxies by extending our reach in the UV through near-IR. This Great Observatory science will be selected through a competed GO program, and will account for about 50% of the HabEx primary mission. The preferred HabEx architecture is a 4m, monolithic, off-axis telescope that is diffraction-limited at 0.4 microns and is in an L2 orbit. HabEx employs two starlight suppression systems: a coronagraph and a starshade, each with their own dedicated instrument
