    Knowledge transfer and management consulting: A look at “The firm”

    Get PDF
    In the authors 'view, a firm's competitive advantage comes from the value it can develop for its customers. Most successful firms today can be considered „intelligent enterprises” because they transform intellectual assets into product and service outputs. It follows that knowledge transfer is especially critical for the functioning of a management consulting firm, because knowledge is the cornerstone of the services such a firm offers its clients

    Strongly Incompatible Quantum Devices

    Full text link
    The fact that there are quantum observables without a simultaneous measurement is one of the fundamental characteristics of quantum mechanics. In this work we expand the concept of joint measurability to all kinds of possible measurement devices, and we call this relation compatibility. Two devices are incompatible if they cannot be implemented as parts of a single measurement setup. We introduce also a more stringent notion of incompatibility, strong incompatibility. Both incompatibility and strong incompatibility are rigorously characterized and their difference is demonstrated by examples.Comment: 27 pages (AMSart), 6 figure

    Common mental disorders in young adults born late-preterm

    Background Results of adulthood mental health of those born late-preterm (34 + 0–36 + 6 weeks + days of gestation) are mixed and based on national registers. We examined if late-preterm birth was associated with a higher risk for common mental disorders in young adulthood when using a diagnostic interview, and if this risk decreased as gestational age increased. Method A total of 800 young adults (mean = 25.3, s.d. = 0.62 years), born 1985–1986, participated in a follow-up of the Arvo Ylppö Longitudinal Study. Common mental disorders (mood, anxiety and substance use disorders) during the past 12 months were defined using the Composite International Diagnostic Interview (Munich version). Gestational age was extracted from hospital birth records and categorized into early-preterm (<34 + 0, n = 37), late-preterm (34 + 0–36 + 6, n = 106), term (37 + 0–41 + 6, n = 617) and post-term (≄42 + 0, n = 40). Results Those born late-preterm and at term were at a similar risk for any common mental disorder [odds ratio (OR) 1.11, 95% confidence interval (CI) 0.67–1.84], for mood (OR 1.11, 95% CI 0.54–2.25), anxiety (OR 1.00, 95% CI 0.40–2.50) and substance use (OR 1.31, 95% CI 0.74–2.32) disorders, and co-morbidity of these disorders (p = 0.38). While the mental disorder risk decreased significantly as gestational age increased, the trend was driven by a higher risk in those born early-preterm. Conclusions Using a cohort born during the advanced neonatal and early childhood care, we found that not all individuals born preterm are at risk for common mental disorders in young adulthood – those born late-preterm are not, while those born early-preterm are at a higher risk. Available resources for prevention and intervention should be targeted towards the preterm group born the earliest

    Molecular Exploration of the First-Century Tomb of the Shroud in Akeldama, Jerusalem

    Get PDF
    The Tomb of the Shroud is a first-century C. E. tomb discovered in Akeldama, Jerusalem, Israel that had been illegally entered and looted. The investigation of this tomb by an interdisciplinary team of researchers began in 2000. More than twenty stone ossuaries for collecting human bones were found, along with textiles from a burial shroud, hair and skeletal remains. The research presented here focuses on genetic analysis of the bioarchaeological remains from the tomb using mitochondrial DNA to examine familial relationships of the individuals within the tomb and molecular screening for the presence of disease. There are three mitochondrial haplotypes shared between a number of the remains analyzed suggesting a possible family tomb. There were two pathogens genetically detected within the collection of osteological samples, these were Mycobacterium tuberculosis and Mycobacterium leprae. The Tomb of the Shroud is one of very few examples of a preserved shrouded human burial and the only example of a plaster sealed loculus with remains genetically confirmed to have belonged to a shrouded male individual that suffered from tuberculosis and leprosy dating to the first-century C.E. This is the earliest case of leprosy with a confirmed date in which M. leprae DNA was detected

    Coverage-dependent structural phase transformations in the adsorption of pentacene on an aperiodically modulated Cu film

    Get PDF
    Surface ordering of pentacene molecules adsorbed on an aperiodic Cu surface has been studied with density functional theory (DFT) and scanning tunnelling microscopy as a function of coverage. Below 0.73 ML (5.3 × 1013 molecules cm−2), the adsorbate structure is row-like with the molecular axes aligned with the rows in the Cu structure. Between this coverage and 1 ML (7.3 × 1013 molecules cm−2), a structural phase with a checkerboard structure is seen. At this coverage region, the molecules are very close to each other which leads to unusual bending. At higher coverages, a further phase transition to a high-density row structure is seen for most of the film. DFT with van der Waals functionals is employed to study how the molecule-molecule and molecule-surface interactions evolve as a function of coverage

    Measurement uncertainty relations

    Get PDF
    Measurement uncertainty relations are quantitative bounds on the errors in an approximate joint measurement of two observables. They can be seen as a generalization of the error/disturbance tradeoff first discussed heuristically by Heisenberg. Here we prove such relations for the case of two canonically conjugate observables like position and momentum, and establish a close connection with the more familiar preparation uncertainty relations constraining the sharpness of the distributions of the two observables in the same state. Both sets of relations are generalized to means of order α\alpha rather than the usual quadratic means, and we show that the optimal constants are the same for preparation and for measurement uncertainty. The constants are determined numerically and compared with some bounds in the literature. In both cases the near-saturation of the inequalities entails that the state (resp. observable) is uniformly close to a minimizing one.Comment: This version 2 contains minor corrections and reformulation

    Dental students’ and patients’ perceived importance and knowledge of dental anxiety

    Abstract Aim: To examine the perceived importance and knowledge of the dental students’ in their treatment of dental anxiety according to their year of study and to find out patients’ perceived importance of the dental students’ knowledge of dental anxiety according to their level on dental fear. Methods: Dental students (N = 219) at the University of Turku and non‐probability convenience sample of 100 of patients attending the Dental Teaching Clinic were given questionnaires with multiple choice and open‐ended questions. Students were categorised into three groups according to the year of study (1–3, 4, 5). Patients were categorised into three groups using the established cut points for Modified Dental Anxiety Scale (no fear = 5–9, low fear = 10–18, high fear = 19–25). The differences between groups were evaluated using cross‐tabulations, chi squared and Fisher’s exact tests. The open‐ended questions were subjected to content analysis. Results: Students’ perceived importance of dental anxiety did not differ between three groups. Students with greater undergraduate education and clinical experience were more likely to have excellent or quite good knowledge (P &lt; 0.001). Patients’ perceived importance of dental students’ knowledge of dental anxiety was greater in patients with high level of fear. The overlapping category that emerged from the open‐ended question analysis was communication skills. This appeared to be important for patients with dental anxiety and for dental students in their management of dental anxiety. Conclusion: Clinical communication skills should be part of dental anxiety management teaching. Dental students should be able to gain sufficient knowledge and skills in treating dental anxiety before graduating
