Psychological and cultural insights into consumption of luxury western brands in India
Get PDFIndia has always had wealthy elites such as the maharajas, upper class and royalty that consume luxury products throughout its consumption history. The relatively recent economic rise of the middle class with an increase in disposable income is leading to consumption of luxury en mass. This qualitative study examines why consumers buy luxury, what they believe luxury is and how their perception of luxury impacts buying behaviour in the context of India. The present study explores luxury constructs drawn from the literature and provides some explanation for luxury consumption behaviour in India. The findings reveal that psychological and cultural factors in Indian society play a major part in shaping luxury consumption. While the findings suggest little support for homogenous luxury preference, Indian consumers share cultural characteristics of lavish consumption of luxury and display of wealth in social functions. Luxury reflects conspicuous consumption and status, and signals wealth for individuals, and conveys social identity and status in Indian society
The Role of Relationally Embedded Network Ties in Resource Acquisition of British Nonprofit Organizations
No full textAs nonprofit and charity organizations face increasing competition, there have been growing interests in how nonprofit organizations conduct commercial activities to raise funds as well as grow their business. However, there is lack of prior research about market-oriented and/or commercial activities in the context of nonprofit business. This study examines the process of how nonprofit organizations use relationally embedded network ties to acquire financial, human, and human capital resources to fulfill their social mission and achieve business growth. The study investigates commercial activity of three U.K.-based nonprofit organizations using the case study method. The findings contribute to insights into components of network ties for acquiring three different network resources of financial, human, and human capital. Nonprofit organizations leverage social mission to improve their ability to acquire network resources. The findings also suggest the charity and social mission of nonprofit business enhance trustworthiness in relationally embedded network ties for resource acquisition

Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
Get PDFThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Effective integration of mechatronics into the mechanical engineering curriculum: A cooperative, project-based learning model with seamless lab-lecture implementation
No full textIn today's competitive markets, engineers face ongoing challenges to produce complex engineering systems with a high level of performance, reliability, value and price. This requires the integration of a number of technologies, which may be accomplished through mechatronics. This paper presents a model for integrating mechatronics education into the Mechanical Engineering curriculum at the American University of Beirut (AUB). A strong component of the model is collaborative, project-based, learning-by-doing experience in which students realize mechatronics devices, possibly of their own choosing, using various laboratory tools including microcontroller technologies. The implementation strategy involves minimal lecturing, a seamless labllecture interface, and just-in-time learning. An example of a typical student's project is presented and course assessment is briefly discussed. © 2005 TEMPUS Publications.Al-Habaibeh A, 2003, INT J ENG EDUC, V19, P615; Auslander DM, 1996, IEEE-ASME T MECH, V1, P5, DOI 10.1109-3516.491404; BERGH CT, P 1999 IEEE ASME INT; CARRYER JE, 1995, MECHATRONICS, V5, P787, DOI 10.1016-0957-4158(95)00046-8; Carryer JE, 2003, INT J ENG EDUC, V19, P581; Djordjevich A, 2003, INT J ENG EDUC, V19, P610; Djordjevich A, 2003, INT J ENG EDUC, V19, P544; DURFEE WK, 1995, MECHATRONICS, V5, P775, DOI 10.1016-0957-4158(95)00044-6; *ENG ACCR COMM ACC, 1997, ENG CRIT 2000 CRIT A; Friedman T., 1999, LEXUS OLIVE TREE; Geddam A, 2003, INT J ENG EDUC, V19, P575; Grimheden M, 2003, INT J ENG EDUC, V19, P569; GUPTA SK, 2003, INT J ENG EDUC, V19, P537; Kyura N, 1996, IEEE-ASME T MECH, V1, P10, DOI 10.1109-3516.491405; LEIFER L, 1997, SUITE 210 MODEL GLOB; Meek S, 2003, MECHATRONICS, V13, P1, DOI 10.1016-S0957-4158(01)00058-7; Murray W.

Probing of Barrier Induced Deviations in Current-Voltage Characteristics of Polymer Devices by Impedance Spectroscopy
No full textTemperature dependent current-voltage measurements have been performed on poly(3-methylthiophene) based devices in metal/polymer/metal geometry in temperature range 90-300 K. Space charge limited current (SCLC) controlled by exponentially distributed traps is observed at all the measured temperatures at intermediate voltage range. At higher voltages, trap-free SCLC is observed at 90 K only while slope less than 2 is observed at higher temperatures which is quiet unusual in polymer devices. Impedance measurements were performed at different bias voltages. The unusual behavior observed in current-voltage characteristics is explained by Cole-Cole plot which gives the signature of interface dipole on electrode/polymer interface. Two relaxation mechanisms are obtained from the real part of impedance vs frequency spectra which confirms the interface related phenomena in the devic

Measurement of the CP-violating phase phi(s) in the B-s(0) -> J/psi phi(1020) -> mu(+)mu-K+K- channel in proton-proton collisions at root s=13 TeV
Get PDFThe CP-violating weak phase ?s and the decay width difference ??s between the light and heavy B0s mass eigenstates are measured with the CMS detector at the LHC in a sample of 48 500 reconstructed B0s? J/I) d (1020) ?11+11? K+K? events. The measurement is based on a data sample corresponding to an integrated luminosity of 96.4 fb?1, collected in proton-proton collisions at ?s = 13 TeV in 2017?2018. To extract the values of ?s and ??s, a time-dependent and flavor-tagged angular analysis of the 11+11?K+K? final state is performed. The analysis employs a dedicated tagging trigger and a novel opposite-side muon flavor tagger based on machine learning techniques. The measurement yields ?s = ?11 ?50 (stat) ? 10 (syst) mrad and ??s = 0.114 ? 0.014 (stat)? 0.007 (syst) ps?1, in agreement with the standard model predictions. When combined with the previous CMS measurement at ?s = 8 TeV, the following values are obtained: ?s = ?21 ? 44 (stat) ? 10 (syst) mrad, ??s = 0.1032 ? 0.0095 (stat) ? 0.0048 (syst) ps?1, a significant improvement over the 8 TeV result. ? 2021 The Author(s).
