This paper assesses the supply of business advice using new empirical evidence from a large-scale survey of SMEs. The chief focus of the paper is on a comparison of suppliers that operate in different environments of regulation, contract and reputation. The paper argues that interaction intensity varies with the level of information asymmetry of these different environments, between different types of service supplier and their clients. Interaction intensity between suppliers also varies as a result of the level of trust they enjoy: for example, the low trust enjoyed by consultants appears to encourage higher intensity of interaction which improves the tailoring of the service to the client's needs and enhances impact. The paper assesses interaction intensity using the existence of site visits and/or a written brief/contract as indicators. Although these measures have limitations, the paper demonstrates clear and significant differences between suppliers in terms of interaction intensity, use of contracts and impact in three broad categories: private-sector consultancy (low trust, high intensity, high impact), business associations (high trust, low intensity, moderate impact) and government support agencies (moderate trust, moderate to high intensity, moderate or low impact). Multivariate estimation methods demonstrate that significant differences in interaction intensity, use of contracts and impact by client type are much less important than differences in supplier type. This indicates that suppliers generally develop more into niche service fields or groups of services rather than niches related to types of firm. 相似文献

The presence of service-level-dependent demand has been empirically observed in industry and is well-documented in the literature. How does the implicit contractual existence of such service dependency impact the ordering decisions of upstream suppliers? We conduct three controlled laboratory experiments to study the impact a service-reward mechanism may have on the upstream ordering decisions of those charged with inventory ordering decisions. The multistudy approach provides representations of decision dynamics across a variety of scenarios, from one-shot buys to long-term supply-chain relationships. Our combined empirical results consistently suggest that the service-reward mechanism significantly and systematically elevates order levels and order variability in a manner that increases departure from optimal ordering. This effect is observed even when decision-makers have incentives to maintain a steady ordering pattern with their suppliers. Our findings shed much-needed light on individual ordering responses to, and the associated risks of, service-reward mechanisms. 相似文献

The current study examined the effects of institutionalization on the discrimination of facial expressions of emotion in three groups of 42‐month‐old children. One group consisted of children abandoned at birth who were randomly assigned to Care‐as‐Usual (institutional care) following a baseline assessment. Another group consisted of children abandoned at birth who were randomly assigned to high‐quality foster care following a baseline assessment. A third group consisted of never‐institutionalized children who were reared by their biological parents. All children were familiarized to happy, sad, fearful, and neutral facial expressions and tested on their ability to discriminate familiar versus novel facial expressions. Contrary to our prediction, all three groups of children were equally capable of discriminating among the different expressions. Furthermore, in contrast to findings at 13–30 months of age, these same children showed familiarity rather than novelty preferences toward different expressions. There were also asymmetries in children’s discrimination of facial expressions depending on which facial expression served as the familiar versus novel stimulus. Collectively, early institutionalization appears not to impact the development of the ability to discriminate facial expressions of emotion, at least when preferential looking serves as the dependent measure. These findings are discussed in the context of the myriad domains that are affected by early institutionalization. 相似文献

The relations among infant anger reactivity, approach behavior, and frontal electroencephalogram (EEG) asymmetry, and their relations to inhibitory control and behavior problems in early childhood were examined within the context of a longitudinal study of temperament. Two hundred nine infants’ anger expressions to arm restraint were observed at 4 months of age. Infants’ approach behaviors during play with an unpredictable toy and baseline frontal EEG asymmetry were assessed at 9 months of age. Inhibitory control during a Go/No‐Go task and parent report of behavior problems were evaluated at 4 years of age. High anger‐prone infants with left, but not right, frontal EEG asymmetry showed significantly more approach behaviors and less inhibitory control relative to less anger‐prone infants. Although a link between anger proneness in infancy and behavior problems in early childhood was not found, a combination of low approach behaviors and poor inhibitory control was predictive of internalizing behaviors. 相似文献

Twenty-one volunteers tested the usability of revisions to the Texas A&M University Libraries' SFX® OpenURL link resolver menus, including the addition of Ex Libris' new bX™ recommendation service and a plug-in which pulls additional information about the journal into the menu. The volunteers also evaluated the quality and desirability of the bX recommendations and discussed their preferences for help options and full-text format. Results of the usability testing are reported along with the resultant menu changes. This study will be of interest to librarians implementing or redesigning OpenURL menus as well as those interested in the user experience. 相似文献

Abstract “Herpes Simplex Virus Proctitis in Homosexual Men: Clinical, Sigmoidoscopic, and Histopathological Features,” Steven E. Goodell, Thomas C. Quinn, Emmanuel Mkrtichian, Michael D. Schuffler, King K. Holmes, and Lawrence Corey. Acute herpes simplex virus (HSV) infection was detected in 23 of 102 consecutively examined, sexually active male homosexuals who presented with anorectal pain, discharge, tenesmus, or hematochezia, as compared with 3 of 75 homosexual men without gastrointestinal symptoms (P < 0.01). Findings that were significantly more frequent in men with HSV proctitis than in men with proctitis due to other infectious causes included fever (48 per cent), difficulty urinating (48 per cent), sacral paresthesias (26 per cent), inguinal lymphadenopathy (57 per cent), severe anorectal pain (100 per cent), tenesmus (100 per cent), constipation (78 per cent), perianal ulcerations (70 per cent), and the presence of diffuse ulcerative or discrete vesicular or pustular lesions in the distal 5 cm of the rectum (50 per cent). Serologic evidence indicated that 85 per cent of the men with symptomatic HSV proctitis were having their first episode of HSV-2 infection. The diagnosis of HSV proctitis is suggested by the presence of severe anorectal pain, and diffuse ulceration of the distal rectal mucosa. (New England Journal of Medicine 1983;308:868–71.) 相似文献

The present investigation explored risk and protective factors for suicidal ideation and behavior in a sub-sample of African American and Latino adolescents (n = 2,626) who participated in the 2004 Centers for Disease Control Youth Violence Survey. Structural equation modeling was used to explore exposure to violence at the community level as a contextual factor that could potentially influence depressive symptomatology, substance abuse, parental support, social support, and suicidality among study participants. Findings indicated that exposure to violence at the community level was not directly related to suicidality among this population of urban adolescents. However, it was directly related with several other variables under study in the model, which in turn were directly related with suicidality. Tests of invariance revealed several across-group differences, particularly by race and gender, in how the identified risk and protective factors in the model related to suicidality. Implications for research and practice with urban, ethnic minority, adolescent populations are discussed. 相似文献
