Organizational Change: An Exploratory Study On Organizational Tightness-Flexibility Dilemmas Of Academicians

In the research, it aims to reveal what are the causes of the behaviors that include organizational tightness-flexibility that academicians experience in educational services, research jobs and community service activities according to their duties and responsibilities, and how they can be prevented. In addition, the aim of the study is to determine the behaviors in which they have a dilemma in the context of organizational tightness-flexibility. The semi-structured interview technique, one of the qualitative research methods, was used in the research. The working group consists of 21 academicians working at state universities located in seven different geographical regions of Turkey. In the analysis of the data, inductive content analysis was used. The concept of organizational scholars firmness oppression, fear, restriction, change closure, vertical hierarchical structure, a phenomenon perceived as bureaucratic and organizational flexibility the concept of autonomy, decision making, initiative, change, and considers the specialization of human relations to be an important phenomenon. The behaviors that academicians perceive as organizational tightness-flexibility are firstly in educational and training services, later on in research jobs, and finally in community service activities. The reasons for the organizational tightness-flexibility behavior of academicians are based on the fact that there is a bureaucratic structure and the personnel recruitment criteria are strict. The fact that universities are autonomous, transparent and accountable also minimizes the dilemmas involving organizational tightness and flexibility. The dilemmas experienced by academicians are to a large extent going beyond the definition of the task.
Easier material management - at what cost?

Intelligent Material Management System, IMMS, was developed in a collaboration between Lyngsoe Systems, a commercial company, and public libraries in Aarhus and Copenhagen, Denmark, with the aim to reduce the time staff spend on managing library materials. The aim of this article is to shed light on what IMMS means for the library practices and hence for the librarian profession. Two research questions will guide the analysis: How do librarians and IMMS interplay at the public library in Copenhagen, Denmark? How does the implementation of IMMS impact the library practices at the branch libraries in Copenhagen, Denmark? With the theoretical lens of practice theory, the article shows how new norms and rules as well as new tools and objects are implemented with IMMS. Librarians need to be able to work with the new objects and tools, the new norms and to create an inspiring library room for library users. Their relation to collection management is changed, and their ability to evaluate materials is not needed in the same way when it comes to selection of titles for the collection. This sometimes creates a tension between the librarian and the system, especially when the librarians’ role in the practice is to perform the decision-making by the algorithm, and not to use their skills to evaluate resources.
Tensor operators and Clebsch–Gordan coefficients of the quantum algebra suq(1,1)

Two kinds of suq(1,1) tensor operators are considered. One of them carries a nonunitary finite dimensional representation of suq(1,1), and the other carries a unitary infinite dimensional representation. Explicit formulas of the former tensor operators are constructed and a useful formula to calculate the matrix elements of rank 1 tensors is derived. By making use of the q analog of the Wigner–Eckart’s theorem, the Clebsch–Gordan coefficient can be extracted from the matrix element of a tensor operator. Explicit formulas of three kinds of the suq(1,1) Clebsch–Gordan coefficients are given, that is, the Clebsch–Gordan coefficient which couples two (non) unitary representations to get the third (non) unitary representation, and the one which couples a nonunitary and a unitary representations to get a new unitary representation. It is shown that these Clebsch–Gordan coefficients and the one of suq(2) can transmute one another by the appropriate replacement of their variables. It is further shown that, by usi.
ASYMMETRIC IMPACTS OF MONETARY POLICY SHOCK ON OUTPUT GAP: EVIDENCE FROM REGIONS IN INDONESIA

We examine the impact of the monetary policy on regional output gaps across 33 Indonesian provinces. Heterogeneous regional responses of the output gap to monetary policy shock are captured using the Vector Autoregressive model. Moreover, the idiosyncratic variations across provinces accounted for different responses are observed with the spatial econometric model. The spatial analysis suggests that economic structure and financial depth positively and significantly determine the aforesaid asymmetric responses. On the other hand, economic size and trade openness have a negative impact on them.
Some comments on passive microwave measurement of rain

Abstract It is argued that because microwave radiation interacts much more strongly with hydrometeors than with cloud particles, microwave measurements from space offer a significant chance of making global precipitation estimates. Over oceans, passive microwave measurements are essentially attenuation measurements that can be very closely related to the rain rate independently of the details of the drop-size distribution. Over land, scattering of microwave radiation by the hydrometeors, especially in the ice phase, can be used to estimate rainfall. In scattering, the details of the drop-size distribution are very important and it is therefore more difficult to achieve a high degree of accuracy. The SSM/I (Special Sensor Microwave Imager), a passive microwave imaging sensor that will be launched soon, will have dual-polarized channels at 85.5 GHz that will be very sensitive to scattering by frozen hydrometeors. Other sensors being considered for the future space missions would extend our ability to estima.
Targeting immune checkpoints: how to use natural killer cells for fighting against solid tumors

Natural killer (NK) cells are unique innate immune cells that mediate anti‐viral and anti‐tumor responses. Thus, they might hold great potential for cancer immunotherapy. NK cell adoptive immunotherapy in humans has shown modest efficacy. In particular, it has failed to demonstrate therapeutic efficiency in the treatment of solid tumors, possibly due in part to the immunosuppressive tumor microenvironment (TME), which reduces NK cell immunotherapy's efficiencies. It is known that immune checkpoints play a prominent role in creating an immunosuppressive TME, leading to NK cell exhaustion and tumor immune escape. Therefore, NK cells must be reversed from their dysfunctional status and increased in their effector roles in order to improve the efficiency of cancer immunotherapy. Blockade of immune checkpoints can not only rescue NK cells from exhaustion but also augment their robust anti‐tumor activity. In this review, we discussed immune checkpoint blockade strategies with a focus on chimeric antigen receptor (CAR)‐NK cells to redirect NK cells to cancer cells in the treatment of solid tumors.
Self-centered leadership and work alienation: A negative social exchange perspective

This paper demonstrates that self-centered leadership behaviors negatively affect the quality of social exchange between the employee and the organization, thus affecting the employee's experience of work alienation. In particular, it proposes that the employee's perceived organizational obstruction and dehumanization sequentially mediate the association between self-centered leadership behaviors and alienation. It examines work alienation in the rarely tapped context of the Egyptian organization and takes into consideration the cultural specialties of the Arab leadership behaviors. This study has collected primary data through questionnaires and used valid and reliable measurement scales. It conducted confirmatory factor analysis, measurement invariance, common method bias test and structural equation modeling in order to analyze the proposed empirical model. The findings reveal that the personalistic and individualistic behaviors of the self-centered leaders are associated with perceived organizational obstruction, dehumanization and work alienation.
Friendly Group Architecture for Securely Promoting Selfish Node Cooperation in Wireless Ad-hoc Network

— Wireless Ad-hoc Network is characterized by a decentralized communication scheme with self-configuring nodes which has witnessed a wide range of practical wireless applications. However, this characteristic also results in various security threats in vulnerable wireless environment irrespective of presence of various routing protocols. Review of existing literature shows that there is very less emphasis towards securing Dynamic Source Routing (DSR) while majority of solutions uses encryption- based operation. Therefore, this manuscript introduces a novel non-encryption-based scheme called as Friendly Group Architecture which intends to identify the presence of selfish node followed by presenting a method to promote the secure cooperation of it. The complete modelling is analytically designed using probability-based computation and dynamic thresholding. The simulation outcome carried out in MATLAB exhibits that it outperforms existing system with respect to energy, overhead, and security.
Physical origin of observed nonlinearities in Poly (1-naphthyl methacrylate): Using a single transistor—transistor logic modulated laser beam

A thermal lens technique is adopted using a single modulated continuous wave (cw) 532-nm laser beam to evaluate the nonlinear refractive index n2, and the thermo-optic coefficient dn/dT, in polymer Poly (1-naphthyl methacrylate) (P-1-NM) dissolved in chloroform, tetrahydrofuran (THF), and dimethyl sulfoxide (DMSO) solvents. The results are compared with Z-scan and diffraction ring techniques. The comparison reveals the effectiveness and the simplicity of the TTL modulation technique. The physical origin is discussed for the obtained results.
EXPERIMENTAL STUDY OF CO2 FORMATION BY SURFACE REACTIONS OF NON-ENERGETIC OH RADICALS WITH CO MOLECULES

Surface reactions between carbon monoxide and non-energetic hydroxyl radicals were carried out at 10 K and 20 K in order to investigate possible reaction pathways to yield carbon dioxide in dense molecular clouds. Hydroxyl radicals, produced by dissociating water molecules in microwave-induced plasma, were cooled down to 100 K prior to the introduction of CO. The abundances of species were monitored in situ using a Fourier transform infrared spectrometer. Formation of CO2 was clearly observed, even at 10 K, suggesting that reactions of CO with OH proceed with little or no activation barrier. The present results indicate that CO2 formation, due to reactions between CO and OH, occurs in tandem with H2O formation, and this may lead to the formation of CO2 ice in polar environments, as typically observed in molecular clouds.
Semiconductor and dielectric microspheres for optoelectronic applications (Invited Paper)

Microspheres possess high quality factor morphology-dependent resonances, i.e., whispering gallery modes. These resonances have narrow linewidths necessary for applications to compact optoelectronic devices for wavelength division multiplexing. The morphology dependent resonances have high quality factors of 104 and 105 with channel spacings of 0.14 nm in glass and 0.05 nm in silicon microspheres.
Colony Transport Affects the Expression of Some Genes Related to the Apis mellifera L. Immune System

Migratory beekeeping can harm the bee colonies if not executed properly. Here, colonies of Apis mellifera were transported (for one or two hours) or not, following proper technical standards. To analyze gene expression (defensin-1, abaecin, and HSP70), forager bees were collected immediately, 24, and 72 hours after transportation. Bee mortality and population growth were measured before and after transportation. This study concludes that transporting honey bee colonies for 2 hours promotes immune system gene expression, although there are no significant changes in bee mortality and population growth of the colonies.
1 0 O ct 2 01 8 Regularized shadowing-based data assimilation method for imperfect models and its comparison to the weak constraint 4 DVar method

We consider a data assimilation problem for imperfect models. We propose a novel shadowing-based data assimilation method that takes model error into account following the Levenberg-Marquardt regularization approach. We illuminate how the proposed shadowing-based method is related to the weak constraint 4DVar method both analytically and numerically. We demonstrate that the shadowing-based method respects the distribution of the data mismatch, while the weak constraint 4DVar does not, which becomes even more pronounced with fewer observations. Moreover, sparse observations give weaker influence on unobserved variables for the shadowing-based method than for the weak constraint 4DVar.
Small signal admittance spectroscopy applied for extraction of charge carrier mobility in thin organic layers

The work presents new way of extraction of charge carrier mobility from small signal spectra of admittance. It can be a useful method for thin organic layers in a sandwich arrangement. It is better than the version of small signal admittance currently applied for getting charge carrier mobility, since the final result is not charged with uncertainty of geometric capacitance and the upper limit of measurable charge carrier mobility is higher.
Change detection of multispectral remote-sensing images using stationary wavelet transforms and integrated active contours

This article presents a change-detection approach for multispectral remote-sensing images. In our approach, we first exploit a wavelet-based, multi-resolution representation of the difference image. For each resolution scale, the multispectral difference image representation is considered as a 2-D Riemannian manifold embedded into a Riemannian manifold with a higher dimensionality. The integrated active contour (IAC) model is then applied to the multiband difference image representation to obtain a change-detection map at a given scale. In order to select a reasonable scale for each pixel, a measurement of regional homogeneity is defined by comparing the determinant of the metric with the average value of the metric’s determinant. For a single pixel, the final change-detection result is generated by selecting the change map on a reasonable scale. Experimental results obtained on multispectral remote-sensing images confirm the effectiveness of the proposed approach, although the time consumption of the approach is somewhat high. Our experiment achieved total error rates of 3.41%, 1.00%, and 1.95% for three data sets, which are comparable to other prevalent algorithms.
Chaos Synchronization of Two Light-Emitting Diode Systems with Complex Dynamics via Adaptive Neural Control

Light-emitting diodes with optoelectronic feedback loop display complex sequences of periodic mixed mode oscillations and chaotic spiking. In this paper, we propose an adaptive neural control scheme for chaos synchronization of two unidirectional coupled LED systems. Based on Lyapunov stability theory, the controller can stabilize the synchronization error dynamics at the origin point, thus chaos synchronization can be obtained. The simulation results demonstrate the effectiveness of the proposed control scheme.
Application of interior point methods to power flow unsolvability

This paper describes an application of an optimal power flow, solved by a direct interior point (IP) method, to restore system solvability. Using the P-Q load representation, power flow unsolvability occurs when, for a given set of active and reactive bus injections, the power flow equations have no real solution. The set of control actions in the IP algorithm includes rescheduling of active power of generators, adjustments on terminal voltage of generators, tap changes on LTC transformers, and as a last resort, minimum load shedding. The IP formulation allows observation of the impact of each control optimization in system solvability. Also described is a framework to calculate probabilistic indicators of solvability problems taking into account the probability of contingencies. The role of control optimization is illustrated in a real 11-bus power system and the probabilistic approach is applied to a 1600-bus power system derived from the Brazilian South/Southeast/Central West system.
Phase-space energy of charged particles with negligible radiation: Proof of spontaneous formation of magnetic structures and new effective forces

The phase-space energy of a system of charged particles in the negligible radiation (Darwin) nonrelativistic limit is derived. The usefulness of the second-order approximation to this Hamiltonian, previously found by the present author, is discussed and given a stronger theoretical foundation. As a result a typical length scale for magnetic structures is found. The virial theorem is then applied to the second-order Hamiltonian. Together with the assumption that magnetism is a first-order perturbation it proves that magnetic interaction lowers the energy of a plasma. This proves that net currents must flow in a plasma and a simple estimate indicates that the spontaneously forming magnetic structures are resistant to thermal disruption. The effective one-particle Hamiltonian implied by the second-order Hamiltonian is calculated. It predicts a new effective many-body force that accelerates charged particles near a large plasma. It is conjectured that this effective force could give a simpler explanation for stellar wind and other large scale plasma phenomena. {copyright} {ital 1997} {ital The American Physical Society}
TESTING THE SIGNIFICANCE OF THE DEPARTURES FROM UTILITY MAXIMIZATION

This paper introduces a general procedure that tests the significance of the departures from utility maximization, departures defined as violations of the general axiom of revealed preference (GARP). This general procedure is based on (i) an adjustment procedure that computes the minimal perturbation in order to satisfy GARP by using the information content in the transitive closure matrix and (ii) a test procedure that checks the significance of the necessary adjustment. This procedure can be easily implemented and programmed, and we run Monte Carlo simulations to show that it is quite powerful.
(Dis-)engaged older men? Hegemonic masculinity, fashion and ageing

Recently, we have witnessed an intensified interest from various fashion scholars on the subject of men and masculine identities. However, while most of the existing research initiatives explore various aspects of masculinity and fashion, they also seem to be limited in their choices of subjects to homosexual and/or young male adults. In this vein, Julia Twigg argues that older men remain ‘largely disengaged from fashion as a cultural field’ (2013a: 19). This article explores the nature of this theoretical disengagement when it comes to older heterosexual men’s lived experience of fashion by drawing on in-depth, semi-structured interviews and personal inventories with a small sample of British men (n=5) based in, or strongly linked to, Nottingham, United Kingdom. In-depth qualitative analysis of the research material revealed various contradictions displayed by the participants in relation to their ageing masculine identities and their often lifelong interest in fashionable clothing. We inspect these discrepancies from two perspectives in which such a disengagement might emerge: between men and fashion and between fashion and ageing. By analysing the findings through Connell’s (2005) influential concept of hegemonic masculinity, we argue that some men both resist and reproduce such a stereotypical disengagement.
2-D multiple reflections

Starting with a 1-D subsurface model, a method is developed for modeling and inverting the class of multiple reflections involving the near‐perfect reflector at the free surface. A solution to the practical problem of estimating the source waveform is discussed, and application of the 1-D algorithm to field data illustrates the successful elimination of seafloor and peg‐leg multiples. Extending the analysis to waves in two dimensions, we make the approximation that the subsurface behaves as an acoustic medium. Based on several numerical and theoretical considerations, the scalar wave equation is split into two separate partial differential equations: one governing propagation of upcoming waves and a second describing downgoing waves. The result is a pair of propagation equations which are coupled where reflectors exist. Finite difference approximations to the initial boundary value problem are developed to integrate numerically the surface reflection seismogram. Use of the 2‐D algorithm for modeling free‐.
