    The large amplitude tunneling motion of the HCl dimer has been directly studied with a tunable farā€infrared laser sideband/two-dimensional free jet expansion spectrometer at hyperfine resolution. Rotationless tunneling rates for the three common chlorine isotopic forms are v(35ā€“35)=463ā€‰979.2(1) MHz, v(35ā€“37)=463ā€‰357.7(1) MHz, and v(37ā€“37)=462ā€‰733.7(3) MHz. Both the rotational constants and hyperfine parameters indicate that the vibrationally averaged structure shows little variation within a given tunneling state, with both HCl bond angles giving an average projection on the a-axis of 47Ā° in all states with resolved hyperfine patterns

    Respect in Organizations: Feeling Valued as ā€œWeā€ and ā€œMeā€

    Research suggests that organizational members highly prize respect but rarely report adequately receiving it. However, there is a lack of theory in organizational behavior regarding what respect actually is and why members prize it. We argue that there are two distinct types of respect: generalized respect is the sense that ā€œweā€ are all valued in this organization, and particularized respect is the sense that the organization values ā€œmeā€ for particular attributes, behaviors, and achievements. We build a theoretical model of respect, positing antecedents of generalized respect from the senderā€™s perspective (prestige of social category, climate for generalized respect) and proposed criteria for the evaluation of particularized respect (role, organizational member, and character prototypicality), which is then enacted by the sender and perceived by the receiver. We also articulate how these two types of respect fulfill the receiverā€™s needs for belonging and status, which facilitates the self-related outcomes of organization-based self-esteem, organizational and role identification, and psychological safety. Finally, we consider generalized and personalized respect jointly and present four combinations of the two types of respect. We argue that the discrepancy between organizational membersā€™ desired and received respect is partially attributable to the challenge of simultaneously enacting or receiving respect for both the ā€œweā€ and the ā€œme.

    High rates of female breeding success and offspring survival are the two major factors in productivity of any commercial livestock industry. To im prove breeding success and offspring survival, the herd m anager will establish selection criteria and choose which males and females will breed. The genetics or characteristics of future animals will reflect their parentage. Selection pressure is evident in both wild and captive populations of herbivores. Predators, environment, and human harvest strategies are a few forces which influence the characteristics of freeranging populations of reindeer, caribou, moose, wapiti, etc. In livestock production systems, herd managers often breed for specific characteristics such as larger body size, high birth and growth rates, leanness, etc. A single color or combination of colors has been another characteristic often selected by purebred cattle producers as well as reindeer herders

    Near-Infrared Spectroscopy of the Bright Kuiper Belt Object 2000 EB173

    Get PDF
    We have obtained a near-infrared spectrum of the bright Kuiper Belt object 2000 EB173; the spectrum appears featureless. The spectrum has a sufficient signal-to-noise ratio to rule out the 1.5 and 2.0 Ī¼m absorption from water ice even at the low level seen in the Centaur Chariklo. In addition, we can rule out a 2.3 Ī¼m absorption at the level seen in the Centaur Pholus

    Emissions of Volatile Organic Compounds Inferred From Airborne Flux Measurements over a Megacity

    Toluene and benzene are used for assessing the ability to measure disjunct eddy covariance (DEC) fluxes of Volatile Organic Compounds (VOC) using Proton Transfer Reaction Mass Spectrometry (PTR-MS) on aircraft. Statistically significant correlation between vertical wind speed and mixing ratios suggests that airborne VOC eddy covariance (EC) flux measurements using PTR-MS are feasible. City-median midday toluene and benzene fluxes are calculated to be on the order of 14.1±4.0 mg/m<sup>2</sup>/h and 4.7±2.3 mg/m<sup>2</sup>/h, respectively. For comparison the adjusted CAM2004 emission inventory estimates toluene fluxes of 10 mg/m<sup>2</sup>/h along the footprint of the flight-track. Wavelet analysis of instantaneous toluene and benzene measurements during city overpasses is tested as a tool to assess surface emission heterogeneity. High toluene to benzene flux ratios above an industrial district (e.g. 10ā€“15 g/g) including the International airport (e.g. 3ā€“5 g/g) and a mean flux (concentration) ratio of 3.2±0.5 g/g (3.9±0.3 g/g) across Mexico City indicate that evaporative fuel and industrial emissions play an important role for the prevalence of aromatic compounds. Based on a tracer model, which was constrained by BTEX (BTEXā€“ Benzene/Toluene/Ethylbenzene/m, p, o-Xylenes) compound concentration ratios, the fuel marker methyl-tertiary-butyl-ether (MTBE) and the biomass burning marker acetonitrile (CH<sub>3</sub>CN), we show that a combination of industrial, evaporative fuel, and exhaust emissions account for >87% of all BTEX sources. Our observations suggest that biomass burning emissions play a minor role for the abundance of BTEX compounds in the MCMA (2ā€“13%)

    ā€œI Identify with Her,ā€ ā€œI Identify with Himā€: Unpacking the Dynamics of Personal Identification in Organizations

    Get PDF
    Despite recognizing the importance of personal identification in organizations, researchers have rarely explored its dynamics. We define personal identification as perceived oneness with another individual, where one defines oneself in terms of the other. While many scholars have found that personal identification is associated with helpful effects, others have found it harmful. To resolve this contradiction, we distinguish between three paths to personal identificationā€”threat-focused, opportunity-focused, and closeness-focused pathsā€”and articulate a model that includes each. We examine the contextual features, how individualsā€™ identities are constructed, and the likely outcomes that follow in the three paths. We conclude with a discussion of how the threat-, opportunity-, and closeness-focused personal identification processes potentially blend, as well as implications for future research and practice
