The equivalence of fluctuation scale dependence and autocorrelations

We define optimal per-particle fluctuation and correlation measures, relate fluctuations and correlations through an integral equation and show how to invert that equation to obtain precise autocorrelations from fluctuation scale dependence. We test the precision of the inversion with Monte Carlo data and compare autocorrelations to conditional distributions conventionally used to study high-$p_t$ jet structure.Comment: 10 pages, 9 figures, proceedings, MIT workshop on correlations and fluctuations in relativistic nuclear collision

Examining the role of sales-based CRM technology and social media use on post-sale service behaviors in India

Despite the growing recognition of the critical role of post-sale service on the salesperson-customer relationship, few studies have explored how salesperson service behaviors (SSB) are enhanced through tools such as sales-based customer relationship management (CRM) technology and social media. Using dyadic salesperson-customer data within a business-to-business context, this study analyzes the direct effects of sales-based CRM technology on the behaviors of diligence, information communication, inducements, empathy and sportsmanship. Additionally, the study examines the interactive effects of sales-based CRM technology and social media on these behaviors. The results indicate that sales-based CRM technology has a positive influence on SSBs and that salespeople using CRM technology in conjunction with social media are more likely to exhibit higher levels of SSBs than their counterparts with low social media technology use

Applicability of Monte Carlo Glauber models to relativistic heavy ion collision data

The accuracy of Monte Carlo Glauber model descriptions of minimum-bias multiplicity frequency distributions is evaluated using data from the Relativistic Heavy Ion Collider (RHIC) within the context of a sensitive, power-law representation introduced previously by Trainor and Prindle (TP). Uncertainties in the Glauber model input and in the mid-rapidity multiplicity frequency distribution data are reviewed and estimated using the TP centrality methodology. The resulting errors in model-dependent geometrical quantities used to characterize heavy ion collisions ({\em i.e.} impact parameter, number of nucleon participants $N_{part}$, number of binary interactions $N_{bin}$, and average number of binary collisions per incident participant nucleon $\nu$) are presented for minimum-bias Au-Au collisions at $\sqrt{s_{NN}}$ = 20, 62, 130 and 200 GeV and Cu-Cu collisions at $\sqrt{s_{NN}}$ = 62 and 200 GeV. Considerable improvement in the accuracy of collision geometry quantities is obtained compared to previous Monte Carlo Glauber model studies, confirming the TP conclusions. The present analysis provides a comprehensive list of the sources of uncertainty and the resulting errors in the above geometrical collision quantities as functions of centrality. The capability of energy deposition data from trigger detectors to enable further improvements in the accuracy of collision geometry quantities is also discussed.Comment: 27 pages, 4 figures, 11 table

Social media and customer relationship management technologies: Influencing buyer-seller information exchanges

Highlights Social media and CRM technology aid salespeople in market sensing and customer-linking activities. Social media utilization enhance the competitive information collection abilities of the seller. CRM techpositively affects seller product information communication, which enablesbuyer information sharing intentions. Sellers capture value from buyers by CRM utilization. Seller experience has significant moderating and explanatory power regarding the use of sales technology. Abstract Due to the increasing array of sales technology, salespeople must understand how each application assists them. This study examines how business-to-business salespeople use different forms of sales technology to meet their boundary-spanning roles. Our research draws from social exchange theory and task-technology fit theory to test a model that examines how salespeople use CRM and social media technologies differentially to support competitive information collection, product information communication, and buyer information sharing. Dyadic data from industrial buyers and sellers is used to analyze the technology-behavior relationships. Our study\u27s results reveal social media use and CRM technology both positively influence buyer-seller information exchanges; however, each technology takes a distinct route to enable the information exchange between the buyer and the seller. The results also suggest that managers need to champion the use of both technology applications to their salesforce

The design, implementation, and assessment of software for use in the teaching of history

(1) In recent years nine arts-related departments at Glasgow University have been successful in winning funds for the creation of large databases. Although these data are being extensively exploited for research, the great potential they offer for undergraduate teaching remains largely untapped due to the lack of suitably tailored software and hardware provision. (2) Our objective is to give arts-based students access to these complex highly structured data in the classroom without requiring them to master difficult operating systems. In this way they would gain valuable transferable skills in information technology. These will enhance the historians' traditional skills of evaluating, interpreting and presenting evidence, long recognized as useful by employers. (3) The scheme will require the establishment of a centrally sited teaching laboratory comprising sixteen micro-computers and fileserver linked to the mainframe through a communications PAD. Chosen to ensure a maximum degree of compatability, the micro-computers (with the appropriate operating system) will be capable of acting as terminals, as a local area network or as single workstations. A facility technician will be employed to supervise the lab's day-to-day running, leaving a programmer/analyst to concentrate exclusively on applying and developing software for the three designated courses. (4) The software will enable students to access and scan files with ease and submit complex search, correlative, and quantitative requests by means of a friendly user interface. It will be possible to generate output in alphanumeric and graphic format either online or in hard copy. Throughout, priority will be given to transferability and portability, particularly in relation to the complementary project at the University of Edinburgh. (5) The project will be directed by Dr. R.H. Trainor consulting with a committee representing the participants - the departments of Modern History, Scottish History and Economic History, the University Archives, the Wellcome Unit for the History of Medicine - and the Computing Service. The latter will provide overall technical supervision. The department of Computing Science will co-operate in formulating an academic staff development programme. With the help of the University adviser on teaching methods the designated courses will be closely monitored in order to assess the value of the particular software, hardware and teaching methods in the project

Measurements of the Crab Pulsar's Giant Radio Pulse Amplitude Power-Law Index Using Low-Frequency Arecibo and Green Bank Telescope Observations

We report two low-frequency measurements of the power-law index for the amplitudes of giant radio pulses from the Crab pulsar. The two observations were taken with the Arecibo and Green Bank radio telescopes at center frequencies of 327 MHz and 350 MHz, respectively. We find best-fit values for the differential power-law index $\beta$ (where $dN/dS \propto S^\beta$ and $S$ is pulse amplitude) of $-2.63 \pm 0.05$ and $-3.6 \pm 0.5$ from the Arecibo and Green Bank data sets, respectively. Both values are broadly consistent with other values previously measured for the Crab pulsar at low radio frequencies. These reported values may be useful in future giant pulse studies of the Crab pulsar.Comment: 7 pages with 1 table and 1 figure. Accepted by The Astrophysical Journa

Microwave-optical double resonance in a erbium-doped whispering-gallery-mode resonator

We showcase an erbium-doped whispering-gallery-mode resonator with optical modes that display intrinsic quality factors better than $10^8$ (linewidths less than 2 MHz), and coupling strengths to collective erbium transitions of up to 2$\pi\times$1.2 GHz - enough to reach the ensemble strong coupling regime. Our optical cavity sits inside a microwave resonator, allowing us to probe the spin transition which is tuned by an external magnetic field. We show a modified optically detected magnetic resonance measurement that measures population transfer by a change in coupling strength rather than absorption coefficient. This modification was enabled by the strong coupling to our modes, and allows us to optically probe the spin transition detuned by more than the inhomogeneous linewidth. We contrast this measurement with electron paramagnetic resonance to experimentally show that our optical modes are confined in a region of large microwave magnetic field and we explore how such a geometry could be used for coherent microwave-optical transduction.Comment: 8 pages, 6 figure
