Efficacy of an intravaginal progesterone insert and an injection of PGF2alpha for synchronizing estrus and shortening the interval to pregnancy in postpartum beef cows, peripubertal beef heifers, and dairy heifers.

Abstract: The objective was to test the efficacy of an intravaginal progesterone insert and injection of PGF2α for synchronizing estrus and shortening the inter- val to pregnancy in cattle. Cattle were assigned to one of three treatments before a 31-d breeding period that employed artificial insemination. Control cattle were not treated, and treated cattle were administered PGF2α or an intravaginal progesterone-releasing insert (CIDR) for 7 d and treated with PGF2α on d 6. The treatments were applied in one of three experiments that involved postpartum beef cows (Exp. 1; n = 851; 56 ± 0.6 d postpar- tum), beef heifers (Exp. 2; n = 724; 442.5 ± 2.8 d of age), and dairy heifers (Exp. 3; n = 260; 443.2 ± 4.5 d of age). Luteal activity before treatment was determined for in- dividual cattle based on blood progesterone concentra- tions. In Exp. 1, there was a greater incidence of estrus during the firs t3do f thebreeding period in CIDR+PGF2α-treated cows compared with PGF2α- treated or control cows (15, 33, and 59% for control, PGF2α, and CIDR+PGF2α, respectively; P < 0.001). The improved estrous response led to an increase in preg- nancy rate during the 3-d period (7, 22, and 36% for control, PGF2α, and CIDR+PGF2α, respectively; P <

Achieving relationship marketing effectiveness in business-to-business exchanges

Abstract: Relationship marketing research and practice operate according to the paradigm that firms should invest in relationship marketing to build better relationships, which will generate improved financial performance. However, findings that relationship marketing efforts vary in their effectiveness across customers and may even be detrimental to performance challenge this belief. This article, therefore, offers a theoretical model that addresses three key issues: 1) what factors determine a customer’s need for relational governance (relationship orientation); 2) what mediating mechanism captures the negative effects of relationship marketing on performance (exchange inefficiency); and 3) how does a customer’s relationship orientation determine the effectiveness of relationship marketing, thus allowing for effective segmentation. The authors demonstrate in an empirical study that the trust in the salesperson and exchange inefficiency both mediate the effect of relationship marketing on seller financial outcomes. In addition, customers’ relationship orientation moderates the impact of relationship marketing on both trust and exchange inefficiency.

Measurement of inclusive jet and dijet production in pp collisions at root s=7 TeV using the ATLAS detector

Abstract: Inclusive jet and dijet cross sections have been measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector at the Large Hadron Collider. The cross sections were measured using jets clustered with the anti-kT algorithm with parameters R=0.4 and R=0.6. These measurements are based on the 2010 data sample, consisting of a total integrated luminosity of 37 inverse picobarns. Inclusive jet double-differential cross sections are presented as a function of jet transverse momentum, in bins of jet rapidity. Dijet double-differential cross sections are studied as a function of the dijet invariant mass, in bins of half the rapidity separation of the two leading jets. The measurements are performed in the jet rapidity range |y|<4.4, covering jet transverse momenta from 20 GeV to 1.5 TeV and dijet invariant masses from 70 GeV to 5 TeV. The data are compared to expectations based on next-to-leading order QCD calculations corrected for non-perturbative effects, as well as to next-to-leading order Monte Carlo predictions. In addition to a test of the theory in a new kinematic regime, the data also provide sensitivity to parton distribution functions in a region where they are currently not well-constrained.
