Organizational Communication and Burnout Symptoms

Job burnout is a psychological response to work stress. Many studies have been conducted measuring burnout and its causes and consequences. The research into causes of burnout brings up various communication-related constructs, but the relationships with feedback employees receive and communication climate is underexposed. This study investigates these relationships. Data for the current study were collected through a web-based questionnaire held among employees of a Dutch subsidiary of an international financial consultancy firm. The questionnaire included the following clusters of independent variables: (a) background variables, (b) work characteristics, (c) communication, and (d) organizational engagement. Of the four clusters of variables, the organizational engagement variables appeared to be the strongest predictors of job burnout. Still, the communication variables also made an important contribution. Particularly the communication climate and the co-worker social support appeared to be important antecedents of job burnout

Managing work-life policies in the European Workplace: explorations for future research

In this paper we focus on the implementation and management of work-life policies in the workplace and the key role of managers in this context. We review the existing literature, enabling us to set a research agenda focused on explaining managerial attitudes and behaviour toward work-life policies in different organisational and national contexts. The evidence found in several studies suggests that managers often receive mixed messages about the implementation of work/life policies because these policies are not embedded in the workplace; managers are often unaware of such policies and lack training in them, leading to inconsistency in implementation and short-term thinking rather than a long-term perspective that cherishes human capital. Our review points to the need for more research allowing a full understanding of managerial attitudes and behaviour in different organisational and national contexts. Although a few interesting studies do exist, research in the field is still in its infancy. More research is needed, in particular systematic studies with well-developed theoretical frameworks.

Working Parents' Use of Work-Life Policies

In this paper, we examine working parent’s use of work-life policies in three financial sector organizations in the Netherlands. We analyse the barriers and support regarding the actual take up of work-life policies by working parents and to what extent this in turn influence their experienced work-life balance. We collected survey data in three Dutch financial sector organizations: one public sector organization and two private firms. All three differ considerably regarding their organizational culture and working practices. Two of the organizations are characterised by a contradictory work-life culture, and one by an approving work-life culture. Findings point out that household characteristics and the work-life culture in the organization determine the take up of work-life policies. With respect to the work-life balance of working parents, organizational culture is an important determinant, no impact is found of the utilization of policies

Slow Equilibration between Spectroscopically Distinct Trap States in Reduced TiO\u3csub\u3e2\u3c/sub\u3e Nanoparticles

© 2017 American Chemical Society. Understanding the nature of charge carriers in nanoscale titanium dioxide is important for its use in solar energy conversion, photocatalysis, and other applications. UV-irradiation of aqueous, colloidal TiO2 nanoparticles in the presence of methanol gives highly reduced suspensions. Two distinct types of electron traps were observed and characterized by EPR and optical spectroscopies. The relative populations of the states depend on temperature, indicating a small energy difference, ΔH° = 3.0 ± 0.6 kcal/mol (130 ± 30 meV). Interconversion between the electron traps occurs slowly over the course of minutes to hours within the temperature range studied here, 0-50 °C. The slow time scale implies that interconversion involves changes in structure or stoichiometry, not just the movement of electrons. This occurrence of slow structural modification with changes in trap state occupancy is likely a general feature of reduced TiO2 systems at thermodynamic equilibria or photostationary states and should be considered in the design of TiO2-containing devices

Non-invasive Angiographic-based Fractional Flow Reserve: Technical Development, Clinical Implications, and Future Perspectives

New non- and less-invasive techniques have been developed to overcome the procedural and operator related burden of the fractional flow reserve (FFR) for the assessment of potentially significant stenosis in the coronary arteries. Virtual FFR-techniques can obviate the need for the additional flow or pressure wires as used for FFR measurements. This review provides an overview of the developments and validation of the virtual FFR-algorithms, states the challenges, discusses the upcoming clinical trials, and postulates the future role of virtual FFR in the clinical practice

Massively parallel computing on an organic molecular layer

Current computers operate at enormous speeds of ~10^13 bits/s, but their principle of sequential logic operation has remained unchanged since the 1950s. Though our brain is much slower on a per-neuron base (~10^3 firings/s), it is capable of remarkable decision-making based on the collective operations of millions of neurons at a time in ever-evolving neural circuitry. Here we use molecular switches to build an assembly where each molecule communicates-like neurons-with many neighbors simultaneously. The assembly's ability to reconfigure itself spontaneously for a new problem allows us to realize conventional computing constructs like logic gates and Voronoi decompositions, as well as to reproduce two natural phenomena: heat diffusion and the mutation of normal cells to cancer cells. This is a shift from the current static computing paradigm of serial bit-processing to a regime in which a large number of bits are processed in parallel in dynamically changing hardware.Comment: 25 pages, 6 figure

Validation of gait event detection by centre of pressure during target stepping in healthy and paretic gait

Background: Target-stepping paradigms are increasingly used to assess and train gait adaptability. Accurate gait-event detection (GED) is key to locating targets relative to the ongoing step cycle as well as measuring foot-placement error. In the current literature GED is either based on kinematics or centre of pressure (CoP), and both have been previously validated with young healthy individuals. However, CoP based GED has not been validated for stroke survivors who demonstrate altered CoP pattern. Methods: Young healthy adults and individuals affected by stroke stepped to targets on a treadmill, while gait events were measured using three detection methods; verticies of CoP cyclograms, and two kinematic criteria, 1) vertical velocity and position and of the heel marker, 2) anterior velocity and position of the heel and toe marker, were used. The percentage of unmatched gait events was used to determine the success of the GED method. The difference between CoP and kinematic GED methods were tested with two one sample (two-tailed) t-tests against a reference value of zero. Differences between group and paretic and non-paretic leg were tested with a repeated measures ANOVA. Results: The kinematic method based on vertical velocity only detected about 80% of foot contact events on the paretic side in stroke survivors while the method on anterior velocity was more successful in both young healthy adults as stroke survivors (3% young healthy and 7% stroke survivors unmatched). Both kinematic methods detected gait events significantly earlier than CoP GED (p<0.001) except for foot contact in stroke survivors based on the vertical velocity. Conclusions: CoP GED may be more appropriate for gait analyses of SS than kinematic methods; even when walking and varying steps
