    This paper presents and discusses findings of a cross-country study of small service firm marketing behavior. These findings demonstrate that small service firms are flexible in the marketing approaches that they adopt. They reveal that such firms are transactional and relational orientated in their marketing activities and that for growing firms, marketing activities are used to create short-term transactions and form relations with key stakeholders. This finding implies that transactional and relationship marketing should be regarded as complementary. The findings presented also demonstrate that the marketing approach selected by participating small firms is determined by a range of customer characteristics of which repeat business is only one. An integrated framework containing elements of transactional and relational approaches is proposed as an appropriate way of describing the marketing behaviours of investigated firms

    This study extended previous research on the effect of employer-provided training and development on employee wages and promotions. Also investigated were differences in the amount or kinds of workplace education provided male and female employees. The study went beyond previous research to examine the effect of missed opportunities , defined as nonparticipation in employer-provided training either because the employee was not allowed to participate or because the employee chose not to participate. Participants completed a questionnaire that captured information about the formal training they had received from their current employer at any time and in the past 12 months. Participants were asked similar questions about informal training in the past 12 months;Relationships were detected between employer-provided training and promotions. No relationships were uncovered between increased wages and workplace education, though increased pay and promotions were found to be related. Gender differences in the kind of training were discovered, with men reporting participation in formal computer training and professional/technical training more frequently than women. Women reported receiving more hours of informal professional/technical training. Few instances of missed opportunities were found among any group at any time

    Comparing and characterizing some constructions of canonical bases from Coxeter systems

    The Iwahori-Hecke algebra H\mathcal{H} of a Coxeter system (W,S)(W,S) has a "standard basis" indexed by the elements of WW and a "bar involution" given by a certain antilinear map. Together, these form an example of what Webster calls a pre-canonical structure, relative to which the well-known Kazhdan-Lusztig basis of H\mathcal{H} is a canonical basis. Lusztig and Vogan have defined a representation of a modified Iwahori-Hecke algebra on the free Z[v,v1]\mathbb{Z}[v,v^{-1}]-module generated by the set of twisted involutions in WW, and shown that this module has a unique pre-canonical structure satisfying a certain compatibility condition, which admits its own canonical basis which can be viewed as a generalization of the Kazhdan-Lusztig basis. One can modify the parameters defining Lusztig and Vogan's module to obtain other pre-canonical structures, each of which admits a unique canonical basis indexed by twisted involutions. We classify all of the pre-canonical structures which arise in this fashion, and explain the relationships between their resulting canonical bases. While some of these canonical bases are related in a trivial fashion to Lusztig and Vogan's construction, others appear to have no simple relation to what has been previously studied. Along the way, we also clarify the differences between Webster's notion of a canonical basis and the related concepts of an IC basis and a PP-kernel.Comment: 32 pages; v2: additional discussion of relationship between canonical bases, IC bases, and P-kernels; v3: minor revisions; v4: a few corrections and updated references, final versio

    A reply to “Historical construction costs of global nuclear power reactors”

    Get PDF
    Lovering et al. (2016) present data on the overnight costs of more than half of nuclear reactors built worldwide since the beginning of the nuclear age. The authors claim that this consolidated data set offers more accurate insights than previous country-level assessments. Unfortunately, the authors make analytical choices that mask nuclear power's real construction costs, cherry pick data, and include misleading data on early experimental and demonstration reactors. For those reasons, serious students of such issues should look elsewhere for guidance about understanding the true costs of nuclear power

    Entrepreneurial Orientation as the Determinant of Entrepreneurial Marketing Behaviors

    Get PDF
    Although entrepreneurial marketing (EM) behaviors are widely reported, there is little discussion on what determines the level of a firm’s behaviors. This study contributes to the knowledge in the fields of entrepreneurship and entrepreneurial marketing by proposing EO, entrepreneurial orientation, as an antecedent of EM behaviors and arguing that EO acts as a multidimensional construct when affecting EM behaviors. The relationships between EO and EM behaviors are empirically investigated using multi-group confirmatory factor analysis and structural equation modeling techniques. Results from the analyses support the hypothesis that EM behaviors are driven by EO. Firms with a higher level of EO engaged in EM behaviors more than firms with a lower level of EO. At the dimension level, innovativeness, proactiveness, and risk-taking are found to independently affect EM behaviors. With innovativeness having the strongest impact, this study concludes that innovativeness is the leading essence of EM behaviors. The results support a new consensus among entrepreneurship research scholars who suggest a direction toward multidimensional EO.

    Optimal Pacing for Running 400 m and 800 m Track Races

    Full text link
    Physicists seeking to understand complex biological systems often find it rewarding to create simple "toy models" that reproduce system behavior. Here a toy model is used to understand a puzzling phenomenon from the sport of track and field. Races are almost always won, and records set, in 400 m and 800 m running events by people who run the first half of the race faster than the second half, which is not true of shorter races, nor of longer. There is general agreement that performance in the 400 m and 800 m is limited somehow by the amount of anaerobic metabolism that can be tolerated in the working muscles in the legs. A toy model of anaerobic metabolism is presented, from which an optimal pacing strategy is analytically calculated via the Euler-Lagrange equation. This optimal strategy is then modified to account for the fact that the runner starts the race from rest; this modification is shown to result in the best possible outcome by use of an elementary variational technique that supplements what is found in undergraduate textbooks. The toy model reproduces the pacing strategies of elite 400 m and 800 m runners better than existing models do. The toy model also gives some insight into training strategies that improve performance.Comment: 14 pages, 4 figures, submitted to the American Journal of Physic

    Risk of suicide among operated and non-operated patients hospitalised for peptic ulcers

    Background: Some small studies have reported high risk of suicide after surgical treatment for peptic ulcer. The aim of the present study was to explore the risk of suicide in hospitalised gastric ulcer and duodenal ulcer patients separately among operated and non-operated cohorts. Methods: Retrospective cohorts of 163 579 nonoperated patients with gastric ulcer or duodenal ulcer and 28 112 patients with surgical treatment for ulcer, recorded in the Swedish Inpatient Register since 1965, were followed from the first hospitalisation, or operation for the surgery cohort, until death, any cancer, emigration, or 31 December 2003. Standardised mortality ratios (SMRs) were calculated, and Poisson regression produced adjusted relative risk estimates among operated and non-operated patients. Results: Non-operated patients hospitalised for peptic ulcer showed a 70% excess risk of suicide (SMR 1.7, 95% CI 1.6 to 1.9) and those who underwent operation had a 60% increased risk (SMR 1.6, 95% CI 1.4 to 1.8). The risk of suicide was very high during the first year after hospitalisation (SMR 4.0, 95% CI 3.4 to 4.7) and more marked among women, patients under 70 and patients hospitalised without complications of ulcer. Both gastric ulcer and duodenal ulcer patients had high risk of suicide completion. Conclusion: Hospitalised patients with gastric ulcer or duodenal ulcer have an increased risk of suicide regardless of surgical treatment. These patients, especially women, are at very high risk during the first year after first hospitalisation/operation. The evaluation and management of suicidal thoughts in patients in medical settings should be further considered

    HydromerR-coated polyurethane (Erythroflex)R catheters, unused, or intravenously inserted for 2-20 days, were studied by scanning electron microscopy (SEM). Both unfixed and fixed (2% glutar-aldehyde in phosphate buffer), and air-or critical-point dried (CPD) specimens were investigated. The catheter segments were sputter-coated with approx. 20 nm gold and studied at an accelerating voltage of 20 kV. The specimens were examined for surface depositions, thickness and structure of the HydromerR layers, and occurrence of adhering and embedded bacteria. The outer HydromerR layer showed, in the un-used specimens, scratches and fissures, as well as adhering foreign bodies. In used specimens, the layer was swollen, with cracks (like dried earth ), and, occasionally , amorphous substances and coccoid bacteria were seen adhering. Damage to the layer, or even its total disappearance was also noted in some specimens. The inner (luminal) HydromerR layer was, in unused specimens, clean and slightly wavy. In used catheters, it was thicker, possibly swollen, with small, isolated or agglomerated protrusions, like a lunar landscape . Adhering platelets and amorphous substances were also occasionally seen. The results suggest that the HydromerR is a fragile material in both its dry and wet forms. Thus, the HydromerR-coated catheters should neither be stored in flexible packs, nor inserted by the Seldinger technique. The findings do not support the belief that the HydromerR-coating can prevent either thrombus formation, or intraluminal occlusion of the in-situ catheters

    Electronic structure and chemical bonding of nc-TiC/a-C nanocomposites

    Full text link
    The electronic structure of nanocrystalline (nc-) TiC/amorphous C nanocomposites has been investigated by soft x-ray absorption and emission spectroscopy. The measured spectra at the Ti 2p and C 1s thresholds of the nanocomposites are compared to those of Ti metal and amorphous C. The corresponding intensities of the electronic states for the valence and conduction bands in the nanocomposites are shown to strongly depend on the TiC carbide grain size. An increased charge-transfer between the Ti 3d-eg states and the C 2p states has been identified as the grain size decreases, causing an increased ionicity of the TiC nanocrystallites. It is suggested that the charge-transfer occurs at the interface between the nanocrystalline TiC and the amorphous C matrix and represents an interface bonding which may be essential for the understanding of the properties of nc-TiC/amorphous C and similar nanocomposites.Comment: 13 pages, 6 figures, 1 table; http://link.aps.org/doi/10.1103/PhysRevB.80.23510
