Pengaruh Kepemimpinan Transformasional, Budaya Organisasi, Dan Kepuasan Kerja Terhadap Komitmen Organisasi Pada Perawat Rumah Sakit Islam Ibnu Sina Pekanbaru
This research conducted to analyze The Influence of Transformasional Leadership, Organizational Culture and Job Satisfaction on Nurse Organizational Commitment (Study at Islam Ibnu Sina Hospital Pekanbaru.) There are independent variables in this research such as Transformasional Leadership (X1), Organizational Culture (X2), Job Satisfaction (X3) and Nurse Organizational Commitment (Y) as dependent variabel. The population of this study were nurse at Islam Ibnu Sina Hospital Pekanbaru and total sample were 108 peoples. Multiple regression method are chosen for data analysis by SPSS version 21. The result of this research shows that Transformasional Leadership, Organizational Culture and Job Satisfaction both simultaneously and partially had effects with Nurse Organizational Commitment at Islam Ibnu Sina Hospital Pekanbaru.. Organization Culture were dominant factor towards Nurse Organizational Commitment. The expectation of this research is Islam Ibnu Sina Hospital Pekanbaru should improve Transformasional Leadership, Organizational Culture and Job Satisfaction among nurse in order to improve Nurse Organizational Commitment
Constraints on Natural MNS Parameters from |U_e3|
The MNS matrix structure emerging as a result of recent neutrino measurements
strongly suggests two large mixing angles (solar and atmospheric) and one small
angle (|U_e3| << 1). Especially when combined with the neutrino mass hierarchy,
these values turn out to impose rather stringent constraints on possible flavor
models connecting the three active fermion generations. Specifically, we show
that an extremely small value of |U_e3| would require fine tuning of Majorana
mass matrix parameters, particularly in the context of seesaw models.Comment: 21 pages, ReVTeX, 2 .eps figure files, updated references and

From Big Data to Rich Theory: Integrating Critical Discourse Analysis with Structural Topic Modeling
Structure, Atomistic Simulations, and Phase Transition of Stoichiometric Yeelimite
ABSTRACT: Yeelimite, Ca4[Al6O12]SO4, is outstanding as an aluminate
sodalite, being the framework of these type of materials flexible and dependent
on ion sizes and anion ordering/disordering. On the other hand, yeelimite is also
important from an applied perspective as it is the most important phase in
calcium sulfoaluminate cements. However, its crystal structure is not well
studied. Here, we characterize the room temperature crystal structure of
stoichiometric yeelimite through joint Rietveld refinement using neutron and Xray
powder diffraction data coupled with chemical soft-constraints. Our structural
study shows that yeelimite has a lower symmetry than that of the previously
reported tetragonal system, which we establish to likely be the acentric
orthorhombic space group Pcc2, with a √2a × √2a × a superstructure based on
the cubic sodalite structure. Final unit cell values were a = 13.0356(7) Å, b =
13.0350(7) Å, and c = 9.1677(2) Å. We determine several structures using
density functional theory calculations, with the lowest energy structure being Pcc2 in agreement with our experimental result.
Yeelimite undergoes a reversible phase transition to a higher-symmetry phase which has been characterized to occur at 470 °C by
thermodiffractometry. The higher-symmetry phase is likely cubic or pseudocubic possessing an incommensurate superstructure,
as suggested by our theoretical calculations which show a phase transition from an orthorhombic to a tetragonal structure. Our
theoretical study also predicts a pressure-induced phase transition to a cubic structure of space group I43m. Finally, we show that
our reported crystal structure of yeelimite enables better mineralogical phase analysis of commercial calcium sulfoaluminate
cements, as shown by RF values for this phase, 6.9% and 4.8% for the previously published orthorhombic structure and for the
one reported in this study, respectively.Universidad de Málaga. Campus de Excelencia Internacional. Andalucía Tech
Partially composite two-Higgs doublet model
In the extra dimensional scenarios with gauge fields in the bulk, the
Kaluza-Klein (KK) gauge bosons can induce Nambu-Jona-Lasinio (NJL) type
attractive four-fermion interactions, which can break electroweak symmetry
dynamically with accompanying composite Higgs fields. We consider a possibility
that electroweak symmetry breaking (EWSB) is triggered by both a fundamental
Higgs and a composite Higgs arising in a dynamical symmetry breaking mechanism
induced by a new strong dynamics. The resulting Higgs sector is a partially
composite two-Higgs doublet model with specific boundary conditions on the
coupling and mass parameters originating at a compositeness scale .
The phenomenology of this model is discussed including the collider
phenomenology at LHC and ILC.Comment: 20 pages, 7 figure
Systematic review of current efforts to quantify the impacts of climate change on undernutrition
The World Health Organization and the Intergovernmental Panel for Climate Change propose undernutrition as the most significant impact of climate change on child health. The question then arises: Where does the empirical evidence to back this claim come from? Current evidence for the impacts of climate on childhood undernutrition draws on a limited number of heterogeneous studies with methodological limitations and is based predominantly on secondary data. Establishing and validating causal pathways among complex confounding factors remain the main challenge in quantifying the climate-attributable fraction of undernutrition. Systematically generating evidence from long-term, high-quality primary data on a range of factors (agricultural, environmental, socioeconomic, and health) at the household level is critical for designing adaptation strategies, particularly for subsistence farmers
