But with respect to human resources it is not only essential to choose the right employees but also to realize the potential of existing competencies. Therefore it cannot simply be a monetary goal but also an immaterial cultural target to provide an atmosphere that allows the abilities of its organization to unfold. The assumption is made that a culture of trust is the adequate instrument to support employee competence utilization; an aspect being of special interest for strategic management. Based on a new integrative model on the impact of trust on employee competence utilization a survey was directed to employees of selected medium sized organizations with between 49 and 999 employees. For the empirical study a pragmatic mixed methods approach was applied. The purpose of this paper is to test the basic hypothesis whether trust actually has an impact on employee competence utilization was tested with the use of correlation analysis and SmartPLS v. 3.2.3 in various ways. Therefore findings are based on the modelling and testing of trust relations and competence utilization. As a result it can be summarized, that deliberate and elaborate concepts of social capital approaches, with a particular emphasis on trust, provide fundamental impact on and feedback through improved and increased employee performance.

The key advantage of the electrophilic tris(carboxylato) bismuth(III) compounds is the unique low absorption of the resulting doped layers which promotes the efficiency of OLED devices. The combination of these features with their low fabrication cost, volatility, and stability, make these materials very attractive as dopants in organic electronics.

The recoiling ion fragments are probed by time-of-flight measurements and two-dimensional velocity map imaging. Correlation analysis of the emission directions of I+ ions recoiling from each end of the molecules reveals significant deviation from axial recoil, i.e., where the I+ ions leave strictly along the I-I symmetry axis. For isolated molecules, the relative angular distribution of the I+ ions is centered at 180∘, corresponding to perfect axial recoil, but with a full width at half maximum of 30∘. For molecules inside He droplets, the width of the distribution increases to 45∘. These results provide a direct measure of the accuracy of Coulomb explosion as a probe of the spatial orientation of molecules, which is particularly relevant in connection with laser-induced molecular alignment and orientation. In addition, our studies show how it is possible to identify fragmentation pathways of the Coulomb explosion for the isolated 1,4–diiodobenzene molecules. Finally, for the 1,4–diiodobenzene molecules in He droplets, it is shown that the angular correlation between fragments from the Coulomb explosion is preserved after they have interacted with the He environment.

The strongest degree of 1D alignment is obtained with four pulses and gives ⟨cos2θ⟩>0.60. Besides the immediate implications for molecular frame studies, our results pave the way for more general manipulation of rotational motion of molecules in He droplets.

Besides a solvent induced shift of the electronic transition frequency, in many cases, a spectral fine structure can be resolved for electronic and vibronic transitions which goes beyond the expected feature of a zero phonon line accompanied by a phonon wing as known from matrix isolation spectroscopy. The spectral shape of the zero phonon line and the helium induced phonon wing depends strongly on the dopant species. Phonon wings, for example, are reported ranging from single or multiple sharp transitions to broad (Δν > 100 cm−1) diffuse signals. Despite the large number of example spectra in the literature, a quantitative understanding of the helium induced fine structure of the zero phonon line and the phonon wing is missing. Our approach is a systematic investigation of related molecular compounds, which may help to shed light on this key feature of microsolvation in superfluid helium droplets. This paper is part of a comparative study of the helium induced fine structure observed in electronic spectra of anthracene derivatives with particular emphasis on a spectrally sharp multiplet splitting at the electronic origin. In addition to previously discussed species, 9-cyanoanthracene and 9-chloroanthracene will be presented in this study for the first time.

This model warrants an empirical explanation of any helium induced substructure resolved for electronic transitions of molecules in helium droplets. Despite a wealth of such experimental data, quantitative modeling of spectra is still in its infancy. The theoretical treatment of such many-particle systems dissolved into a quantum fluid is a challenge. Moreover, the success of theoretical activities relies also on the accuracy and self-critical communication of experimental data. This will be elucidated by a critical resume of our own experimental work done within the last ten years. We come to the conclusion that spectroscopic data and among others in particular the spectral resolution depend strongly on experimental conditions. Moreover, despite the fact that none of the helium induced fine structure speaks against the empirical model for solvation in helium droplets, in many cases an unequivocal assignment of the spectroscopic details is not possible. This ambiguity needs to be considered and a careful and critical communication of experimental results is essential in order to promote success in quantitatively understanding microsolvation in superfluid helium nanodroplets.

We find that for the typical case of a strong, nonresonant laser field and a weak static electric field complete 3D orientation is induced if the laser field is elliptically polarized and if its major and minor polarization axes are not parallel to the static field. For a linearly polarized laser field solely the dipole moment component along the most polarizable axis of the molecule is relevant resulting in 1D orientation even when the laser polarization and the static field are nonparallel. Simulations show that the dipole moment component perpendicular to the most-polarizable axis becomes relevant in a strong dc electric field combined with the laser field. This offers an alternative approach to 3D orientation by combining a linearly polarized laser field and a strong dc electric field arranged at an angle equal to the angle between the most polarizable axis of the molecule and its permanent dipole moment.

According to the published spectroscopic work including microwave, infrared, and electronic spectroscopy, the latter appears to be particularly promising to study microsolvation because of the appearance of pure molecular transitions and spectrally separated phonon wings. Instead of studying the very details of the influence of the helium environment for one particular dopant molecule as previously done for phthalocyanine, the present study compares electronic spectra of a series of non-polar porphyrin derivatives when doped into helium droplets consisting of 104–105 helium atoms. Thereby, we focus on the helium-induced fine structure, as revealed most clearly at the corresponding electronic origin. The interpretation and the assignment of particular features obtained in the fluorescence excitation spectra are based on additional investigations of dispersed emission spectra and of the saturation behavior. Besides many dopant-specific results, the experimental study provides strong evidence for a particular triple peak feature representing the characteristic signature of helium solvation for all seven related dopant species.

The alignment sharpens as the laser intensity is increased, similar to the behavior in gas phase. For diiodobenzene the highest degree of alignment, ⟨cos2θ2D⟩=0.90, is essentially identical to the value obtained for isolated molecules in a supersonic beam, whereas the highest degrees of alignment for iodobenzene and for methyliodide in helium droplets fall below the values obtained for isolated molecules. We believe this is due to the deviation from axial recoil in the Coulomb explosion process that probes the alignment of the molecules in the He droplets.

Still trust is a resource of strategic relevance since it establishes security, reduces complexity and opens potentials being bigger than simply the reduction of "cost of control". These characteristics are of special interest for management, as competent action is always bound to problem-solving-abilities under circumstances of insecurity. Further to this there are numerous situations where control is not applicable and where we simply don’t have full knowledge. Also trust is particular as it bypasses financial efforts and grows through usage; an investment of high amortization though that deserves closer attention of management especially valid in times of skilled worker shortage and with respect to organizational learning as a valuable competitive advantage. The purpose of this paper is to develop direct and indirect measurable on the impact of trust on employee competence utilization and its subsequent realization in a strategic scorecard approach. This is based on a new integrative model in the organizational context applicable for strategicmanagement. With this the objective of the paper is to answer the question if culture of trust is an adequate instrument for strategic management. The empirical evaluation of the model is based on a survey directed to employees of selected companies in a pragmatic mixed methods application. The selected view considers the trust level of employees with regard to management as another individual and the organization itself; personal and institutional trust mechanisms are affected.Thus the employee evaluates its management. As a result, the empirical study suggests that it is possible to specify frameworks for the establishment of trust, and that its impact on competence utilization is moreover significant. However the concept of trust creates challenging requirements on managers. Based on the assumption that employees basically think and act in the sense of the company, benevolence and goodwill must be involved to avoid an opportunistic approach. Further to this accountability, shared norms and freedom to take responsibility need to be proven by behavior. The allowance of constructive seriously taken criticism, problem solving attitude, the acceptance of decisions are further key points for trust supporting frameworks that have to be accepted and shown through behavior.
