Using cross-functional, cross-firm teams to co-create value: The role of financial measures

Increasingly, the involvement of representatives from all major business functions in cross-functional, crossfirmteams is being viewed as a means to develop and maintain profitable business-to-business relationships.However, if the measurements of the value co-created in these relationships with customers and suppliers donot incorporate the financial outcomes of joint cross-functional initiatives, managers can be led to makedecisions that jeopardize the long-term profitability of the two firms. In this paper, the authors explore thedifferences in value co-creation when a company is linked to key customers and key suppliers through crossfunctionalteams and when it is not. Using a case study approach, the authors measured value co-creation infinancial terms and describe how managers changed their behaviors toward customers and suppliers whenthey were able to compare the value that was being co-created in each relationship. In each pair ofrelationships, one involved cross-functional teams and the other did not. The results indicate that crossfunctional,cross-firm involvement leads to increased value co-creation. The research suggests that marketingscholars and managers should emphasize the use of cross-functional teams that involve all major functions tomanage relationships with key customers, and should incorporate financial measures in the evaluation ofrelationship performance

5D Yang-Mills instantons from ABJM Monopoles

In the presence of a background supergravity flux, N M2-branes will expand via the Myers effect into M5-branes wrapped on a fuzzy three-sphere. In previous work the fluctuations of the M2-branes were shown to be described by the five-dimensional Yang-Mills gauge theory associated to D4-branes. We show that the ABJM prescription for eleven-dimensional momentum in terms of magnetic flux lifts to an instanton flux of the effective five-dimensional Yang-Mills theory on the sphere, giving an M-theory interpretation for these instantons.Comment: 29 pages, Latex; v2: added references and a comment on the graviphoton coupling in section 5; v3: typos corrected and references adde

A preliminary test of Abelian D4-M5 duality

We compute the partition function of five-dimension Abelian sYM including a graviphoton term on a five-torus. The result agrees with Abelian M5 brane partition function with zero characteristics on an associated six-torus.Comment: 7 page

Characteristics of emotional disturbance of female and male students in elementary, middle, and high school

Provide data on the five characteristics of emotional disturbance (ED). For 503 students with ED and 2016 without disabilities, teachers rated the characteristics (Inability to Learn; Relationship Problems; Inappropriate Behavior; Unhappiness or Depression; Physical Symptoms or Fears), plus Socially Maladjusted. We applied a 2 (ED, without disabilities) × 2 (female, male) × 3 (elementary, middle, high school) covariance analysis, with follow‐up comparisons. Students with ED showed greater problems than students without disabilities on all five characteristics, and Socially Maladjusted. On Inability to Learn, among students with ED genders did not differ at elementary but males had greater problems at middle school. On Inappropriate Behavior and Physical Symptoms or Fears, students with ED varied across school levels but students without disabilities did not. All five characteristics discriminated students with ED from those without disabilities. Differences between genders and school levels varied across characteristics

(2,0) theory on circle fibrations

We consider (2,0) theory on a manifold M_6 that is a fibration of a spatial S^1 over some five-dimensional base manifold M_5. Initially, we study the free (2,0) tensor multiplet which can be described in terms of classical equations of motion in six dimensions. Given a metric on M_6 the low energy effective theory obtained through dimensional reduction on the circle is a Maxwell theory on M_5. The parameters describing the local geometry of the fibration are interpreted respectively as the metric on M_5, a non-dynamical U(1) gauge field and the coupling strength of the resulting low energy Maxwell theory. We derive the general form of the action of the Maxwell theory by integrating the reduced equations of motion, and consider the symmetries of this theory originating from the superconformal symmetry in six dimensions. Subsequently, we consider a non-abelian generalization of the Maxwell theory on M_5. Completing the theory with Yukawa and phi^4 terms, and suitably modifying the supersymmetry transformations, we obtain a supersymmetric Yang-Mills theory which includes terms related to the geometry of the fibration.Comment: 24 pages, v2 References added, typos correcte

Heterotic AdS_3/CFT_2 duality with (0,4) spacetime supersymmetry

We discuss the AdS_3/CFT_2 duality of a heterotic three-charge model with (0,4) target space supersymmetry. The worldsheet theory for heterotic strings on the AdS_3 x S^3/Z_N x T^4 near-horizon geometry was constructed by Kutasov, Larsen and Leigh in [hep-th/9812027]. We propose that the dual conformal field theory is given by a two-dimensional (0,4) sigma model arising on the Higgs branch of an orbifolded ADHM model. As a non-trivial consistency check of the correspondence, we find that the left- and right-moving central charges of the infrared conformal field theory agree with those predicted by the worldsheet model. Moreover, using the entropy function formalism, we show that to next-to-leading order the central charge can also be obtained from an alpha'-corrected supergravity theory.Comment: 34 pages, 2 figures, references added, to be published in Nucl.

Supersymmetric Gauge Theories on the Five-Sphere

We construct Euclidean 5d supersymmetric gauge theories on the five-sphere with vector and hypermultiplets. The SUSY transformation and the action are explicitly determined from the standard Noether procedure as well as from off-shell supergravity. Using localization techniques, the path-integral is shown to be restricted to the integration over a generalization of instantons on CP^2 and the Coulomb moduli.Comment: 22 pages; v2: a reference adde

Deconstructing graviphoton from mass-deformed ABJM

Mass-deformed ABJM theory has a maximally supersymmetric fuzzy two-sphere vacuum solution where the scalar fields are proportional to the TGRVV matrices. We construct these matrices using Schwinger oscillators. This shows that the ABJM gauge group that corresponds to the fuzzy two-sphere geometry is $U(N)\times U(N-1)$. We deconstruct the graviphoton term in the D4 brane theory. The normalization of this term is fixed by topological reasons. This gives us the correct normalization of the deconstructed U(1) gauge field and fixes the Yang -Mills coupling constant to the value which corresponds to M5 brane compactified on \mb{R}^ {1,2} \times S^3/{\mb{Z}_k}. The graviphoton term also enable us to show that the zero mode contributions to the partition functions for the D4 and the M5 brane agree.Comment: 26 page

Practicing dental hygienists' attitudes toward the proposed Advanced Dental Hygiene Practitioner: a pilot study

The purpose of this pilot study was to assess the attitudes of active registered dental hygienists toward the proposed Advanced Dental Hygiene Practitioner (ADHP). Factors of support/interest in the ADHP concept, level of practice, and socio-demographics were examined. A self-administered questionnaire was mailed to 1562 active registered dental hygienists in Colorado, Kentucky, and North Carolina. Both quantitative and qualitative analyses were performed. The response rate was 29% (n = 442). Overall level of support/interest for the ADHP, indicated by cumulative totals of very and somewhat supportive/interested, was respectively 87%/74% in Colorado, 82%/71% in Kentucky, and 92%/81% in North Carolina. A significant difference was found among respondents interested in becoming an ADHP and those not interested (p<0.05). The overall level of support/interest in the proposed ADHP does not differ among the three states. A revised questionnaire and survey procedures could further improve measurement of dental hygienists' attitudes regarding the ADHP program
