    Employee performance is a form of employee achievement after going through various stages in the work process and can be used to find out the extent of employee success and failure in the work. Based on the observations showed that the performance of MSME employees in Kalibawang, Girimulyo and Nanggulan subdistricts was not optimal. This is allegedly because it is influenced by islamic capital, marketing, and motivation. The formulation of problems in this research is whether capital and marketing can affect the performance of employees directly or through the Islamic motivation of MSMEs in three subdistricts in Kulon Progo Regency, Yogyakarta. This study aims to find out the influence of capital and marketing on the performance of employees with islamic motivation covariance on MSMEs Kulon Progo Regency, this study uses the archeal The Posttest Only Control Group with islamic motivation covariance. Data collection techniques use interviews and questionnaires, while sampling techniques use non probability sampling with a sample number of 68 people. The results showed that capital and marketing have a positive and significant effect on employee performance through Islamic motivation. This can be seen from the results of simple linear regression analysis, multiple linear regression, t test, determination coefficient test, sobel test and path analysis. Islamic motivation as a moderator variable mediates between the capital to the performance of employees who are partial mediation and Islamic motivation as moderator variables that mediate between marketing to employee performance, both of which are full mediation

    In rowing, perfect synchronisation is important for optimal performance of a crew. Remarkably, a recent study on ergometers demonstrated that antiphase crew coordination might be mechanically more efficient by reducing the power lost to within-cycle velocity fluctuations of the boat. However, coupled oscillator dynamics predict the stability of the coordination to decrease with increasing stroke rate, which in case of antiphase may eventually yield breakdowns to in-phase. Therefore, this study examined the effects of increasing stroke rate on in- and antiphase crew coordination in rowing dyads. Eleven experienced dyads rowed on two mechanically coupled ergometers on slides, which allowed the ergometer system to move back and forth as one 'boat'. The dyads performed a ramp trial in both in- and antiphase pattern, in which stroke rates gradually increased from 30 strokes per minute (spm) to as fast as possible in steps of 2 spm. Kinematics of rowers, handles and ergometers were captured. Two dyads showed a breakdown of antiphase into in-phase coordination at the first stroke rate of the ramp trial. The other nine dyads reached between 34-42 spm in antiphase but achieved higher rates in in-phase. As expected, the coordinative accuracy in antiphase was worse than in in-phase crew coordination, while, somewhat surprisingly, the coordinative variability did not differ between the patterns. Whereas crew coordination did not substantially deteriorate with increasing stroke rate, stroke rate did affect the velocity fluctuations of the ergometers: fluctuations were clearly larger in the in-phase pattern than in the antiphase pattern, and this difference significantly increased with stroke rate. Together, these results suggest that although antiphase rowing is less stable (i.e., less resistant to perturbation), potential on-water benefits of antiphase over in-phase rowing may actually increase with stroke rate

    Objective: To investigate the comparison between rectovaginal examination (RVT), transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) as diagnostic tools for identifying various Deep Infiltrating Endometriosis (DIE).   Methods: Prospective longitudinal study was done involving 31 women referred for surgical management of DIE. Calculation of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of RVT, TVUS and MRI for DIE were recorded.   Results: The mean age was 35.1 years. DIE were present in 95.45% of women which commonly located at uterosacral ligaments (58.33%), followed by rectovaginal (16,67%), rectosigmoid- colon (16.67%) and bladder-ureter (8.3%). TVUS had the best accuracy (RVT 50.24%; TVUS 88.85%; MRI 75.77%) among other diagnostic tools for nodules located at uterosacral ligaments (RVT 52.63%; TVUS 87%; MRI 40%) and rectovaginal (RVT 76.75%; TVUS 93.34%; MRI 80%), but it poorly identified nodules located at rectosigmoid (RVT 20%; TVUS 65.56%; MRI 88.75%) and bladder-ureteral area (RVT 50.44%; TVUS 87.66%; MRI 93.55%). RVT had good PPV (88.89%) but bad NPV (32.01%) profile, made it worth to be a screening diagnostic tool.   Conclusion: RVT was a good screening diagnostic tools as it could be done easily but was weak in diagnosing anterior DIE. TVUS gave a better diagnosis rates on DIE located at sacrouterina ligaments and rectovaginal area whereas MRI did better on bowel DIE (rectosigmoid- colon area) and urological DIE (bladder-ureteral area).    Keywords: deep infiltrating endometriosis, magnetic resonance imaging, tranvaginal ultrasonograph

    Case Report: Sublingual Microcirculatory Alterations in a Covid-19 Patient With Subcutaneous Emphysema, Venous Thrombosis, and Pneumomediastinum

    The Corona virus disease 2019 (Covid-19) has brought a wide range of challenges in intensive care medicine. Understanding of the pathophysiology of Covid-19 relies on interpreting of its impact on the vascular, particularly microcirculatory system. Herein we report on the first use of the latest generation hand-held vital microscope to evaluate the sublingual microcirculation in a Covid-19 patient with subcutaneous emphysema, venous thrombosis and pneumomediastinum. Remarkably, microcirculatory parameters of the patient were increased during the exacerbation period, which is not a usual finding in critically ill patients mostly presenting with a loss of hemodynamic coherence. In contrast, recovery from the disease led to a subsequent amelioration of these parameters. This report clearly shows the importance of microcirculatory monitoring for evaluating the course and the adequacy of therapy in Covid-19 patients

    Creating spaces: testimonio, impossible knowledge, and academe

    Get PDF
    Postprint upload.This article examines what it means to engage seriously with speech and writing events, such as testimonio, articulated by people whose theoretical base lies primarily in experience outside the walls of academe. I argue that we dismiss such unfamiliar scholarship to the detriment of all involved. If we are truly committed to learning, then we must expose ourselves to language forms and cultural norms that are different from those with which we are familiar. We must learn from them how to acknowledge the limits of our analysis and how to find “impossible knowledge” in unaccustomed places

    Disparities in Healthcare Utilisation Rates for Aboriginal and Non-Aboriginal Albertan Residents, 1997-2006: A Population Database Study

    Background: It is widely recognised that significant discrepancies exist between the health of indigenous and nonindigenous populations. Whilst the reasons are incompletely defined, one potential cause is that indigenous communities do not access healthcare to the same extent. We investigated healthcare utilisation rates in the Canadian Aboriginal population to elucidate the contribution of this fundamental social determinant for health to such disparities. Methods: Healthcare utilisation data over a nine-year period were analysed for a cohort of nearly two million individuals to determine the rates at which Aboriginal and non-Aboriginal populations utilised two specialties (Cardiology and Ophthalmology) in Alberta, Canada. Unadjusted and adjusted healthcare utilisation rates obtained by mixed linear and Poisson regressions, respectively, were compared amongst three population groups - federally registered Aboriginals, individuals receiving welfare, and other Albertans. Results: Healthcare utilisation rates for Aboriginals were substantially lower than those of non-Aboriginals and welfare recipients at each time point and subspecialty studied [e.g. During 2005/06, unadjusted Cardiology utilisation rates were 0.28% (Aboriginal, n = 97,080), 0.93% (non-Aboriginal, n = 1,720,041) and 1.37% (Welfare, n = 52,514), p = ,0.001]. The age distribution of the Aboriginal population was markedly different [2.7%$65 years of age, non-Aboriginal 10.7%], and comparable utilisation rates were obtained after adjustment for fiscal year and estimated life expectancy [Cardiology: Incidence Rate Ratio 0.66, Ophthalmology: IRR 0.85]. Discussion: The analysis revealed that Aboriginal people utilised subspecialty healthcare at a consistently lower rate than either comparatively economically disadvantaged groups or the general population. Notably, the differences were relatively invariant between the major provincial centres and over a nine year period. Addressing the causes of these discrepancies is essential for reducing marked health disparities, and so improving the health of Aboriginal people

    Developing an interatomic potential for martensitic phase transformations in zirconium by machine learning

    Interatomic potentials: predicting phase transformations in zirconium Machine learning leads to a new interatomic potential for zirconium that can predict phase transformations. A team led by Hongxian Zong at Xi’an Jiaotong University, China, and Turab Lookman at Los Alamos National Laboratory, U.S.A, used a Gaussian-type machine learning approach to produce an interatomic potential that predicted phase transformations in zirconium. They expressed each atomic energy contribution via changes in the local atomic environment, such as bond length, shape, and volume. The resulting machine-learning potential successfully described pure zirconium’s physical properties. When used in molecular dynamics simulations, it predicted a zirconium phase diagram as a function of both temperature and pressure that agreed well with previous experiments and simulations. Developing learnt interatomic potentials in phase-transforming systems could help us better simulate complex systems

    Laterally focused attention modulates asymmetric coupling in rhythmic interlimb coordination.

    Peters (J Motor Behav 21:151-155, 1989; Interlimb coordination: neural, dynamical and cognitive constraints, Academic, Orlando, pp 595-615, 1994) suggested that expressions of handedness in bimanual coordination may be reflections of an inherent attentional bias. Indeed, previous results indicated that focusing attention on one of the limbs affected the relative phasing between the limbs in a manner comparable to the effects of hand dominance. The present study extended the comparison between the effects of attentional focus and handedness by testing their impact on the interactions between the limbs. Both left-handed and right-handed participants performed rhythmic bimanual coordination tasks (in-phase and antiphase coordination), while directing attention to either limb. Using brief mechanical perturbations, the degree to which the limbs were influenced by each other was determined. The results revealed that the non-dominant limb was more strongly affected by the dominant limb than vice versa and that, in line with Peters' proposition, this handedness-related asymmetry in coupling strength was reduced when attention was focused on the non-dominant limb, thereby highlighting the potential relation between inherent (handedness-related) asymmetries and voluntary attentional asymmetries. In contrast to previous findings, the (commonly observed) phase lead of the dominant limb was attenuated (rather than accrued) when attention was focused on this limb. This unexpected result was explained in terms of the observed attention-related difference in amplitude between the limbs. © 2006 Springer-Verlag
