Does leadership effectiveness correlates with leadership styles in healthcare executives of Iran University of Medical Sciences

Background: Effective leadership is essential to passing through obstacles facing the health field. The current health care system in Iran has major problems and gaps in the field of effective leadership. The aim of this study was to evaluate hospital managers' leadership style through self-assessment and to determine the correlation between leadership styles with healthcare executives' leadership readiness and leadership effectiveness. Methods: In this cross-sectional study a self-administered questionnaire completed by all internal healthcare executives of all teaching and non-teaching hospitals affiliated to Iran University of Medical Sciences. Questionnaire was composed to determine demographic information, leadership style questions, leadership effectiveness and leadership readiness. Descriptive statistics and Pearson correlation coefficient were used for data analysis. Results: According to the findings, the dominant style of healthcare executives was transformational leadership style (with a score of 4.34). The leadership effectiveness was estimated at about 4.36 that shows the appropriate level of leadership effectiveness. There was a significant correlation (correlation coefficient of 0.244) between leadership readiness and transformational leadership style (p<0.05). Also, there was a significant correlation between leadership effectiveness with transformational (0.051) and transactional (0.216) styles. Conclusion: There was a correlation between leadership readiness and leadership effectiveness with leadership styles. Application of this research will be crucial to universities and healthcare executives. This study suggests that strengthening the scientific basis is essential for leadership readiness and leadership effectiveness in healthcare system

Policy analysis of Iranian pharmaceutical sector; A qualitative study

Introduction: Improving public health through providing affordable and accessible pharmaceuticals is among the concerns of governments worldwide. This study aimed to analyze Iran�s pharmaceutical sector policies in order to identify the challenges and suggest some strategic solutions to overcome such challenges. Methods: Top managers (15), middle managers (10), and operational managers (5) working in the Food and Drug Administration of Iranian Ministry of Health along with community pharmacists (5) participated in a qualitative study using semi-structured in-depth interviews. Data were recorded, transcribed, and then analyzed via MAXQDA 10 software. Results: Policies for national pharmaceutical sector were divided into four groups of �research & development�, �import & export�, �pharmaceutical procurement�, and �pharmaceutical supply and distribution�. Then, the challenges faced by each sector were extracted. Considering the challenges, some policy options were recommended for growth and development of national pharmaceutical sector. Conclusion: Iran�s pharmaceutical sector has managerial and administrative differences compared with overseas pharmaceutical sectors. These differences are the main reasons for the current status of Iran�s pharmaceutical sector and have put Iran behind foreign pharmaceutical sectors. Iran�s pharmaceutical sector has endured many critical periods during recent decades and has gained great experience during these stages. Therefore, it is believed that Iran�s pharmaceutical sector, with its experience and potential, is capable of producing world-level medicines. © 2019 Ebadi Fardazar et al

Mixed Wino Dark Matter: Consequences for Direct, Indirect and Collider Detection

In supersymmetric models with gravity-mediated SUSY breaking and gaugino mass unification, the predicted relic abundance of neutralinos usually exceeds the strict limits imposed by the WMAP collaboration. One way to obtain the correct relic abundance is to abandon gaugino mass universality and allow a mixed wino-bino lightest SUSY particle (LSP). The enhanced annihilation and scattering cross sections of mixed wino dark matter (MWDM) compared to bino dark matter lead to enhanced rates for direct dark matter detection, as well as for indirect detection at neutrino telescopes and for detection of dark matter annihilation products in the galactic halo. For collider experiments, MWDM leads to a reduced but significant mass gap between the lightest neutralinos so that chi_2^0 two-body decay modes are usually closed. This means that dilepton mass edges-- the starting point for cascade decay reconstruction at the CERN LHC-- should be accessible over almost all of parameter space. Measurement of the m_{\tz_2}-m_{\tz_1} mass gap at LHC plus various sparticle masses and cross sections as a function of beam polarization at the International Linear Collider (ILC) would pinpoint MWDM as the dominant component of dark matter in the universe.Comment: 29 pages including 19 eps figure

Mixed Higgsino Dark Matter from a Large SU(2) Gaugino Mass

We observe that in SUSY models with non-universal GUT scale gaugino mass parameters, raising the GUT scale SU(2) gaugino mass |M_2| from its unified value results in a smaller value of -m_{H_u}^2 at the weak scale. By the electroweak symmetry breaking conditions, this implies a reduced value of \mu^2 {\it vis \`a vis} models with gaugino mass unification. The lightest neutralino can then be mixed Higgsino dark matter with a relic density in agreement with the measured abundance of cold dark matter (DM). We explore the phenomenology of this high |M_2| DM model. The spectrum is characterized by a very large wino mass and a concomitantly large splitting between left- and right- sfermion masses. In addition, the lighter chargino and three light neutralinos are relatively light with substantial higgsino components. The higgsino content of the LSP implies large rates for direct detection of neutralino dark matter, and enhanced rates for its indirect detection relative to mSUGRA. We find that experiments at the LHC should be able to discover SUSY over the portion of parameter space where m_{\tg} \alt 2350-2750 ~GeV, depending on the squark mass, while a 1 TeV electron-positron collider has a reach comparable to that of the LHC. The dilepton mass spectrum in multi-jet + \ell^+\ell^- + \eslt events at the LHC will likely show more than one mass edge, while its shape should provide indirect evidence for the large higgsino content of the decaying neutralinos.Comment: 36 pages with 26 eps figure

Direct, Indirect and Collider Detection of Neutralino Dark Matter In SUSY Models with Non-universal Higgs Masses

In supersymmetric models with gravity-mediated SUSY breaking, universality of soft SUSY breaking sfermion masses m_0 is motivated by the need to suppress unwanted flavor changing processes. The same motivation, however, does not apply to soft breaking Higgs masses, which may in general have independent masses from matter scalars at the GUT scale. We explore phenomenological implications of both the one-parameter and two-parameter non-universal Higgs mass models (NUHM1 and NUHM2), and examine the parameter ranges compatible with Omega_CDM h^2, BF(b --> s,gamma) and (g-2)_mu constraints. In contrast to the mSUGRA model, in both NUHM1 and NUHM2 models, the dark matter A-annihilation funnel can be reached at low values of tan(beta), while the higgsino dark matter annihilation regions can be reached for low values of m_0. We show that there may be observable rates for indirect and direct detection of neutralino cold dark matter in phenomenologically aceptable ranges of parameter space. We also examine implications of the NUHM models for the Fermilab Tevatron, the CERN LHC and a Sqrt(s)=0.5-1 TeV e+e- linear collider. Novel possibilities include: very light s-top_R, s-charm_R squark and slepton_L masses as well as light charginos and neutralinos and H, A and H^+/- Higgs bosons.Comment: LaTeX, 48pages, 26 Figures.

Exploring the BWCA (Bino-Wino Co-Annihilation) Scenario for Neutralino Dark Matter

In supersymmetric models with non-universal gaugino masses, it is possible to have opposite-sign SU(2) and U(1) gaugino mass terms. In these models, the gaugino eigenstates experience little mixing so that the lightest SUSY particle remains either pure bino or pure wino. The neutralino relic density can only be brought into accord with the WMAP measured value when bino-wino co-annihilation (BWCA) acts to enhance the dark matter annihilation rate. We map out parameter space regions and mass spectra which are characteristic of the BWCA scenario. Direct and indirect dark matter detection rates are shown to be typically very low. At collider experiments, the BWCA scenario is typified by a small mass gap m_{\tilde Z_2}-m_{\tilde Z_1} ~ 20-80 GeV, so that tree level two body decays of \tilde Z_2 are not allowed. However, in this case the second lightest neutralino has an enhanced loop decay branching fraction to photons. While the photonic neutralino decay signature looks difficult to extract at the Fermilab Tevatron, it should lead to distinctive events at the CERN LHC and at a linear e^+e^- collider.Comment: 44 pages, 21 figure

Mixed Higgsino Dark Matter from a Reduced SU(3) Gaugino Mass: Consequences for Dark Matter and Collider Searches

In gravity-mediated SUSY breaking models with non-universal gaugino masses, lowering the SU(3) gaugino mass |M_3| leads to a reduction in the squark and gluino masses. Lower third generation squark masses, in turn, diminish the effect of a large top quark Yukawa coupling in the running of the higgs mass parameter m_{H_u}^2, leading to a reduction in the magnitude of the superpotential mu parameter (relative to M_1 and M_2). A low | mu | parameter gives rise to mixed higgsino dark matter (MHDM), which can efficiently annihilate in the early universe to give a dark matter relic density in accord with WMAP measurements. We explore the phenomenology of the low |M_3| scenario, and find for the case of MHDM increased rates for direct and indirect detection of neutralino dark matter relative to the mSUGRA model. The sparticle mass spectrum is characterized by relatively light gluinos, frequently with m(gl)<<m(sq). If scalar masses are large, then gluinos can be very light, with gl->Z_i+g loop decays dominating the gluino branching fraction. Top squarks can be much lighter than sbottom and first/second generation squarks. The presence of low mass higgsino-like charginos and neutralinos is expected at the CERN LHC. The small m(Z2)-m(Z1) mass gap should give rise to a visible opposite-sign/same flavor dilepton mass edge. At a TeV scale linear e^+e^- collider, the region of MHDM will mean that the entire spectrum of charginos and neutralinos are amongst the lightest sparticles, and are most likely to be produced at observable rates, allowing for a complete reconstruction of the gaugino-higgsino sector.Comment: 35 pages, including 26 EPS figure

Medical records standards in selected countries and Iran: a comparative study.

Studies conducted in Iran showed that the absence of specific and applied standards relating to medical records, and the absence of a custodian organization, resulted in an incompatibility of medical records with standards and a deviation in the path of the activities of medical records departments from their main goals. Today's medical record professionals identified the development of a mechanism for establishing medical records standards as a reform priority. So, conducting a comparative study of related medical records standards in developed countries with Iran, is important in order to facilitate a nationwide standardization movement in Iran's medical record departments

The relationship between hospital managers' leadership style and effectiveness with passing managerial training courses

Background: Effective leadership that rises from managerial training courses is highly constructive in managing hospitals more effectively. This study aims at investigating the relationship between leadership effectiveness with providing management training courses for hospital managers. Methods: This was a cross-sectional study carried out on top and middle managers of 16 hospitals of Iran University of Medical Sciences. As a sample, 96 participants were selected through census method. Data were collected using leadership effectiveness and style questionnaire, whose validity and reliability were certified in previous studies. Pearson correlation coefficient and linear regressions were used for data analysis. Results: Leadership effectiveness score was estimated to be 4.36, showing a suitable status for managers' leadership effectiveness compared to the set criteria. No significant difference was found between leadership effectiveness and styles among managers who had passed the training courses with those who had not (p > 0.05). Conclusion: Passing managerial training courses may have no significant effect on managers' leadership effectiveness, but there may be some other variables which should be meticulously studied

Effect of educational intervention based on PRECEDE-PROCEED model combined with self-management theory on self-care behaviors in type 2 diabetic patients

Aims: Diabetes mellitus is a chronic and progressive disease which requires ongoing medical care as well as patient's self-care skills to prevent acute complications. The purpose of this study is to determine the effect of the PRECEDE-PROCEED model combined with self-management theory on self-care behaviors in type 2 diabetic patients. Methods: In this semi-experimental study, 86 type 2 diabetic patients referred to the diabetes clinic of Ardabil were randomly selected and divided into two groups (n = 43). Patients in group 1 received educations based on PRECEDE-PROCEED model combined with self-management theory while patients in group 2 received only educations based on PRECEDE-PROCEED model. The self-made questionnaire was used to measure demographic information and PRECEDE-PROCEED model variables at baseline and one month after the intervention. Results: The mean scores of knowledge, attitude, self-efficacy (p = 0.001), self-care (p = 0.001), enabling factors, and reinforcing factors had significant differences in both groups before and after the intervention (p < 0.05). In addition, one month after the intervention, the mean scores of attitude, self-efficacy, self-care, and reinforcing factors were significantly higher in group 1 compared to group 2. Conclusion: The results indicate the effectiveness of an educational intervention based on PRECEDE-PROCEED model combined with self-management theory to improve self-care behaviors in patients with type 2 diabetes. © 2018 Diabetes Indi
