Bullying and organisational politics in competitive and rapidly changing work environments

This paper argues that workplace bullying can in some cases be a form of organisational politics, that is, a deliberate, competitive strategy from the perspective of the individual perpetrator. A cross-sectional study conducted among business professionals revealed that there was a correlation between a politicised and competitive climate and bullying. This finding implies that globalisation, increased pressures for efficiency, and restructuring, which limits the number of management positions and thereby contributes to increased internal competition, may lead to more bullying. The findings have important implications for management, since the possible political aspects of bullying must be taken into account in order to be able to undertake successful prevention and intervention measures.
Untersuchung von strukturbildenden zellulären Prozessen im Kontext des tissue engineerings: alginat-basierte Gerüststrukturen

The combination of (Bio-)materials with therapeutically relevant cells is a challenging field in Tissue Engineering and Regenerative Medicine. Novel cellular environments require a sophisticated design in order to provide an optimal microenvironment for sensitive cell types like human stem cells. This thesis focuses on the study of alginate modifications designing novel cell niches. The initial developments are conducted using twodimensional substrates and are transferred in consequence to three-dimensional scaffolds. Physiological conditions are not only mandatory for the analysis and cultivation of cells, but also for the final recovery. Using a novel parallelized approach for living cell microscopy, systematic studies with respect to the modification of alginate hydrogels were performed. The results demonstrate that covalent coupling of tyramine molecules on alginate to be suitable for direct and indirect adhesion of human stem cells. In addition, gentle teatments for scaffold degradation using alginat lyases as well as first promising approaches for an automated engineering of scaffolds are established in this work. The knowledge gained from performed studies was finally transferred to free-floating, three-dimensional scaffolds.

16. LATE PLIOCENE TO HOLOCENE (2.6Ð0 MA) WESTERN EQUATORIAL ATLANTIC DEEP-WATER CIRCULATION: INFERENCES FROM BENTHIC STABLE ISOTOPES 1

Oxygen and carbon isotope records measured in epibenthic foraminifers ( Cibicides wuellerstorÞ, Cibicides spp., and Nuttalides umbonifera ) are presented for Sites 925 (3041 m water depth), 927 (3315 m), and 929 (4356 m), recovered during Ocean Drilling Program (ODP) Leg 154 at the northeast slope of the Ceara Rise, western equatorial Atlantic. These records comprise the time interval from 2.6 to 0 Ma. Dating is based on tuning variations of the magnetic susceptibility records to orbital parameters using the 1,1 solution of Laskar. The isotope records of all sites are exceptionally coherent and show a cyclicity dominated by a 41-k.y. cycle during the late Pliocene and the early Pleistocene and a 100-k.y. cyclicity during the late Pleistocene. Carbon isotope records show a varying depth gradient during the studied period. For interglacials, a difference of 0.3a resects the modern pattern of admixing of Lower Circumpolar Deep Water into the overlying North Atlantic Deep Water (NADW). During glacials, carbon isotope values of shallow and deep sites differ by up to 1.0a, but converge since 1.6 Ma, and especially since 1.0 Ma. The evolution of Atlantic to PaciÞc carbon isotope gradients is examined using a record of the western equatorial PaciÞc ODP Site 806B (2520 m). From 2.6 to 1.6 Ma glacial reductions in NADW are less than those observed between 1.6 and 0 Ma. During the mid-Pleistocene (0.7Ð0.3 Ma), glacial carbon isotope values of even the shallower Atlantic cores are indistinguishable from PaciÞc values from approximately the same depth.
Semiparametric model averaging of ultra-high dimensional time series

In this paper, we consider semiparametric model averaging of the nonlinear dynamic time series system where the number of exogenous regressors is ultra large and the number of autoregressors is moderately large. In order to accurately forecast the response variable, we propose two semiparametric approaches of dimension reduction among the exogenous regressors and auto-regressors (lags of the response variable). In the first approach, we introduce a Kernel Sure Independence Screening (KSIS) technique for the nonlinear time series setting which screens out the regressors whose marginal regression (or auto-regression) functions do not make significant contribution to estimating the joint multivariate regression function and thus reduces the dimension of the regressors from a possible exponential rate to a certain polynomial rate, typically smaller than the sample size; then we consider a semiparametric method of Model Averaging MArginal Regression (MAMAR) for the regressors and auto-regressors that survive the screening procedure, and propose a penalised MAMAR method to further select the regressors which have significant effects on estimating the multivariate regression function and predicting the future values of the response variable. In the second approach, we impose an approximate factor modelling structure on the ultra-high dimensional exogenous regressors and use a well-known principal component analysis to estimate the latent common factors, and then apply the penalised MAMAR method to select the estimated common factors and lags of the response variable which are significant. Through either of the two approaches, we can finally determine the optimal combination of the significant marginal regression and auto-regression functions. Under some regularity conditions, we derive the asymptotic properties for the two semiparametric dimension-reduction approaches. Some numerical studies including simulation and an empirical application are provided to illustrate the proposed methodology.
AN EMPIRICAL INVESTIGATION INTO THE INFLUENCES OF PSYCHOLOGICAL EMPOWERMENT AND OVERALL JOB SATISFACTION ON EMPLOYEE LOYALTY: THE CASE OF MALAYSIAN FRONT OFFICE RECEPTIONISTS

The hotel industry has the responsibility and role of increasing guest satisfaction with its services and products. This can be carried out through efficient service by frontline employees, particularly the Front Office receptionists. Developing an efficient workforce may depend on their sense of belonging or loyalty to the organization. There are many ways and means of developing employees’ levels of loyalty to their organization. Empowering employees and high job satisfaction levels are among the studied factors that influence positive employee outcomes. This study was conducted to examine the influences of psychological empowerment and overall job satisfaction on the employee loyalty of Front Office Receptionists in Kuala Lumpur 5-star hotels. A total of 210 questionnaires were distributed at 21 hotels rated as 5-star hotels in Kuala Lumpur, Malaysia. Results showed that employee psychological empowerment does not have any significant impacts on loyalty. However, the findings suggested that overall job satisfaction did have a significant influence on loyalty. Hotel managers might consider more competitive solutions in their effort to increase the employee’s loyalty, for example by enhancing participation in the departmental decision making, encourage creativity, implementing a better work environment and employment packages.
Lecithin soybean phospholipid nano‐transfersomes as potential carriers for transdermal delivery of the human growth hormone

Pharmaceutical molecules such as peptides and proteins are usually injected into the body. Numerous efforts have been made to find new noninvasive ways to administer these peptides. In this study, highly flexible vesicles (transfersomes [TFs]) were designed as a new modern transdermal drug delivery system for systemic drug administration through the skin, which had also been evaluated in vitro. In this study, two growth hormone‐loaded TF formulations were prepared, using soybean lecithin and two different surfactants; F1_sodium deoxycholate and F 2_sodium lauryl sulfate. Thereafter, the amount of skin penetration by the two formulas was assessed using the Franz diffusion cell system. TF formulations were evaluated for size, zeta potential and in vitro skin penetration across the rat skin. Results indicated that vesicle formulations were stable for 4 weeks and their mean sizes were 241.33 ± 17 and 171 ± 12.12 nm in the F 1 and F 2 formulation, respectively. After application to rat skin, transport of the human growth hormone (hGH) released from the TF formulations was found to be higher than that of the hGH alone. Maximum amounts of transdermal hormone delivery were estimated to be 489.54 ± 8.301 and 248.46 ± 4.019 ng·cm−2 , for F 1 and F 2, respectively. The results demonstrate the capability of the TF‐containing growth hormone in transdermal delivery and superiority of the F 1 to F 2 TFs.
Linking particle properties to dense suspension extrusion flow characteristics using discrete element simulations

Extrusion is a widely used process for forming suspensions and pastes into designed shapes, and is central to the manufacture of many products. In this article, the extrusion through a square-entry die of non-Brownian spheres suspended in Newtonian fluid is investigated using discrete element simulations, capturing individual particle-particle contacts and hydrodynamic interactions. The simulations reveal inhomogeneous velocity and stress distributions, originating in the inherent microstructure formed by the constituent particles. Such features are shown to be relevant to generic paste extrusion behavior, such as extrudate swell. The pressure drop across the extruder is correlated with the extrudate flow rate, with the empirical fitting parameters being linked directly to particle properties such as surface friction, and processing conditions such as extruder wall roughness. Our model and results bring recent advances in suspension rheology into an industrial setting, laying foundations for future model development, predictive paste formulation and extrusion design. © 2016 American Institute of Chemical Engineers AIChE J, 63: 3069–3082, 2017

Quantum cluster theories

Quantum cluster approaches offer new perspectives to study the complexities of macroscopic correlated fermion systems. These approaches can be understood as generalized mean-field theories. Quantum cluster approaches are non-perturbative and are always in the thermodynamic limit. Their quality can be systematically improved, and they provide complementary information to finite size simulations. They have been studied intensively in recent years and are now well established. After a brief historical review, this article comparatively discusses the nature and advantages of these cluster techniques. Applications to common models of correlated electron systems are reviewed.
Does bulk-needle (cid:14) 13 C reflect short-term discrimination?

– When bulk needle material is analysed for its carbon isotope signal, the net d 13 C underlies variation of the biochemical composition of the needle. Bulk needle material can be categorized into two different types of carbon pools, differing in the time period of assimilation: structural carbon and carbon with a rapid turnover. The bulk needle d 13 C is influenced by the relative amounts of the two pools. In the present study the d 13 C of rapid turnover carbon was estimated using gas exchange measurements. When these were compared to the respective bulk needle d 13 C, a significant linear correlation was found (raw data: p < 0.0005; R 2 = 0.25 / daily means: p < 0.05; R 2 = 0.39), indicating that the rapid turnover carbon pool influences the overall d 13 C. Therefore one has to be aware that bulk-needle d 13 C measurements can have the tendency either toward reflecting the d 13 C of structural carbon or toward reflecting the d 13 C of rapid turnover carbon. R 2 = 0,25 / moyenne journalière: p < 0,05 ; R 2 = 0,49) a été trouvée, montrant que le pool de carbone à rotation rapide influence le d 13 C total. Par conséquent, si on utilise des mesures de d 13 C d'une aiguille entière il faut être conscient que les résultats peuvent refléter la composition isotopique du carbone structurel ou à renouvellement rapide. aiguille / discrimination / isotope du carbone / échange du gaz / Pinus sylvestris
Mechanical and Structural Properties of Zinc – Sodium - Phosphate Glasses Doped with Cu 2 O

Ternary Zinc-Sodium-Phosphate glasses doped with copper of the composition 40ZnO-(20-x) Na 2 O-40P 2 O 5 -xCu 2 O where x =0, 2, 4, 6, 8 mol % were prepared by the tradition quenching method. The effect of Cu ions on density, molar volume and microhardness has been investigated. FTIR was measured in the range (400-1600) cm-1 to investigate the effect of Cu ion on the structure of the studied glass. Longitudinal and shear velocities were measured for the studied glass using pulse echo technique. Elastic properties such as longitudinal modulus, shear modulus, bulk modulus, and Young’s modulus, Poisson’s ratio) and some physical parameters such as softening temperature, hardness, Debye temperature have been calculated. The ultrasonic results and the other measured parameters indicate the Cu ion increase the cross-link density by the formation of P-O-Cu. All the measurements are measured at room temperature.
Robust platform for engineering pure-quantum-state transitions in polariton condensates

We report on pure-quantum-state polariton condensates in optical annular traps. The study of the underlying mechanism reveals that the polariton wave function always coalesces in a single pure quantum state that, counter-intuitively, is always the uppermost confined state with the highest overlap with the exciton reservoir. The tunability of such states combined with the short polariton lifetime allows for ultrafast transitions between coherent mesoscopic wave functions of distinctly different symmetries, rendering optically confined polariton condensates a promising platform for applications such as many-body quantum circuitry and continuous-variable quantum processing.

Modeling the Liquid Water Transport in the Gas Diffusion Layer for Polymer Electrolyte Membrane Fuel Cells Using a Water Path Network

In order to model the liquid water transport in the porous materials used in polymer electrolyte membrane (PEM) fuel cells, the pore network models are often applied. The presented model is a novel approach to further develop these models towards a percolation model that is based on the fiber structure rather than the pore structure. The developed algorithm determines the stable liquid water paths in the gas diffusion layer (GDL) structure and the transitions from the paths to the subsequent paths. The obtained water path network represents the basis for the calculation of the percolation process with low calculation efforts. A good agreement with experimental capillary pressure-saturation curves and synchrotron liquid water visualization data from other literature sources is found. The oxygen diffusivity for the GDL with liquid water saturation at breakthrough reveals that the porosity is not a crucial factor for the limiting current density. An algorithm for condensation is included into the model, which shows that condensing water is redirecting the water path in the GDL, leading to an improved oxygen diffusion by a decreased breakthrough pressure and changed saturation distribution at breakthrough.

Ranking of Five Star Hotels from the Perspective of Corporate Social Responsibility Dimensions

The present study aims to rank the five-star hotels in Iran from the perspective of cooperate social responsibility (CSR) dimensions. The study is descriptive, and the population includes all of the Iranian five-star hotels, the number of which has been determined to amount to 26. Due to the limited number of hotels as well as the aim of the study, sampling has not been done, and the whole population has come under investigation. For data collection, a questionnaire, designed by the researcher, has been used. To validate the questionnaire, its face validity has been taken into consideration, and the reliability of the questionnaire has been calculated separately for each CSR dimension using Cronbach’s alpha coefficient. To analyze the data, the fuzzy TOPSIS method has been used. The results show that Homa Hotel in Bandar Abbas ranks first among the hotels in regard to CSR dimensions.
Mechanical properties of inorganic nanowire reinforced polymer–matrix composites

The mechanical properties of poly(vinyl alcohol) matrix composites incorporating SiC and Al2O3 nanowires (NWs) have been investigated. A marked increase in the elastic modulus (up to 90%) has been observed even with the addition of a small quantity (0.8 vol%) of nanowires. This observation cannot be explained by iso-stress analysis, which is appropriate for describing the variation of properties with the reinforcement volume fraction in discontinuously reinforced composites. Crystallization of the polymer induced by the NWs, the high aspect ratio and the surface-to-volume ratio of the NWs as well as the possible in-plane alignment of the NWs during processing are considered to be responsible for the increase in the stiffness. A significant increase in the strength of the composite with the addition of NWs is also observed. This is due to the significant pull-out of the NWs and the corresponding stretching of the matrix due to the complete wetting of the NW surface by the polymer. The increase in tensile strength is found to saturate at higher vol% of NW addition due to the reduced propensity for shear-band induced plastic deformation.
