Job characteristics, burnout and the relationship with recovery experiences

Orientation: Job characteristics (consisting of job demands and job resources) have an impact on burnout. However, it is unclear whether recovery strategies might influence this relationship amongst staff members at a tertiary education institution in South Africa. Research purpose: The primary objective of this study was to determine whether recovery strategies influence and moderate the relationship between job demands, job resources and burnout. Motivation for the study: Recovery strategies may influence and buffer the negative effects of job demands on burnout and may influence and enhance the positive influence of job resources on burnout. Research approach, design and method: Cross-sectional data was collected amongst employees at a tertiary education institution ( N = 366). Main findings: The results of the structural equation modelling revealed significant positive relationships between work pressure, emotional demands and a lack of social support with burnout. Also, work pressure was related to all four recovery strategies and different job resources were associated with different recovery strategies. Finally, mastery experiences were the only recovery strategy that significantly predicted burnout. Practical/managerial implications: Employees are encouraged to engage in recovery strategies that will reduce their burnout levels, especially mastery experiences. Contribution/value-add: This study adds to the body of literature on effort recovery in South Africa. Very little empirical research has been done in South Africa regarding the use and benefits of different recovery strategies. Recommendations for future research are made.

Mediating Effect of Self-worth and Depression on the Relationship between Subjective Age and Subjective Well-being of the Elderly

This paper aims to disclose the mediating effect of self-worth and depression on the relationship between subjective age and subjective well-being of the elderly. For this purpose, 238 questionnaires were issued to elderly in Shaanxi, China. 219 (92.02%) of valid questionnaires were returned. During the survey, the respondents evaluated each item on the questionnaire against the age decade scale (ADS), geriatric depression scale (GDS-11), geriatric self-worth scale (GSWS) and Memorial University of Newfoundland Scale of Happiness (MUNSH). The main conclusions are as follows: Feel age, look age, behavior age and interest age were all lower than the actual age; The old people with a high level of education and a high involvement in leisure activities tend to have a young subjective age; Subjective age had a significant effect on subjective well-being, self-worth and depression, while self-worth and depression mediated the relationship between subjective age and subjective well-being. Therefore, the subjective well-being among the elderly can be promoted by reducing subjective age and enhancing self-worth. This research provides new insights into the research on subjective well-being of elderly.
MEASURING THE DIMENSIONS AND ATTRIBUTES OF LIVEABILITY OF LOW-INCOME HOUSING COMMUNITIES IN NIGERIA

Housing is a basic human need and its liveability transcends beyond the perimeter of the housing unit. The quality of the living environment is important for an individualâ€™s wellbeing. The factors that contribute to the inhabitantsâ€™ satisfaction in a living environment are essential inputs in monitoring the success of housing policies of the government. This paper measured the dimensions and attributes of the living environment of the public low income housing estates in Minna, Niger State. A questionnaire was administered to 400 household heads in the three selected housing estates based on stratified random sampling. 366 questionnaires were returned and the data were analyzed with descriptive statistics and factor analysis. Results showed that residents are satisfied with housing unit and economic vitality, but dissatisfied with neighbourhood facilities, and socialinteraction was lacking among the residents. Also, residents are apprehensive of their safety. This study recommends an immediate improvement of neighbourhood facilities in these housing estates.
The root anchorage ability of Salix alba var. tristis using a pull-out test

The vegetation materials may reduce soil erosion and runoff, create space for breeding and habitat and they are commonly used in river ecological engineering. Therefore, it is important to select the soilbioengineering plant by taking its growth characteristics and the soil solidity of its root system as the major considerations. Because Salix alba var. tristis has a strong capability of keeping moisture, preventing drought and reducing wind, we selected it as a model species for soil bioengineering research and application in Beijing, China. In this study, we aimed to investigate the soil-reinforcing effects by Salix alba var. tristis. We performed a pull-out test on 4 year live stakes and measured their morphological characteristics. Our results showed that, the plant had a satisfactory root development after 4 years, and the pull-out resistive force had the strongest correlations with the morphological parameters of plant, such as height (R 2 = 0.79, P < 0.001) and diameter at shoot base (R 2 = 0.69, P < 0.001
Linking job insecurity to negative decision making: The mediating role of job tension

Job insecurity has increased markedly in the developed economies of the world (Gray, 2002). The effects of job insecurity on individual employees and on organisational outcomes, however, are controversial. For instance, Greenhalgh and Rosenblatt (1984) point out that job insecurity can result in increased work effort, while Dekker and Schaufeli, (1995) argue that insecurity leads to stress and decreased performance. In this paper, we outline a study examining the indirect impact of job insecurity on decision-making, via job-related tension. Based on a web survey involving 217 participants, we found that job insecurity indirectly increased the adoption of negative decision-making strategies by increasing employees’ level of job-related tension. Limitations and implications for theory and managers are also discussed.
Pneumococcal meningitis in Cuban children and adolescents: A fifteen years follow up

Pneumococcal meningitis still remains a serious global threat for children and adolescents. The aim of this study was to assess main epidemiological features of Pneumococcal meningitis, some risks for fatality and major pneumococcal serogroup/serotypes and their potential coverage by the available pneumococcal conjugate vaccines. An observational study of 569 confirmed cases (1998-2012) was completed based on surveillance system. Incidence, case-fatality rate and seasonality were estimated. Association of different variables related with dead was assessed by using Relative Risk and its 95% confidence interval with p 0.05) in 6-11, 12-14 and 1519 years old (Relative Risk=3.61, 3.00 and 3.16 respectively). Proportion of S. pneumoniae isolates covered by commercial pneumococcal conjugate vaccines ranked 53.0-71.4%. Pneumococcal meningitis affects predominantly infants and is particularly lethal in Cuba. Seasonal increase occurs in winter. Hospitalization ≥24 hours may contribute to increase fatality. Main S. pneumoniae serogroups/serotypes circulating among Cuban children and adolescents are included in commercial pneumococcal conjugated vaccines. We emphasize the importance of continuous nationwide surveillance to achieve more comprehensive insights into pneumococcal epidemiology as well as their contribution to the assessment of future immunization strategies.
What Drives Business R&D Intensity Across OECD Countries?

This paper empirically investigates the potential determinants of business-sector R&D intensity using a panel of OECD countries for the period of 1970-2002 with data measured as five-year year averages. Estimates using a system GMM estimator controlling for endogeneity show a high degree of persistence in business-sector R&D. Tax incentives for R&D have a significant and positive impact on business R&D spending regardless of specification and estimation techniques. Furthermore, we find that expenditures on R&D performed by universities are significantly positively related to the business enterprise sector expenditures on R&D indicating that public sector R&D and private R&D are complements. Direct R&D subsidies and the high-tech export share are significantly positively related to business-sector intensity but these effects are only significant using the first-differenced GMM estimator. Static fixed effects results show that countries characterised by a low level mark-up ratio appear to have higher R&D intensities but this effect disappears after controlling for lagged R&D intensity. Similarly, the Ginarte-Park index of patent rights is significantly positively related to
Radiative equilibrium in solar prominences reconsidered

Aims. We reconsider the question which kinetic temperatures can lead to prominence configurations that are in radiative equilibrium. We compare these temperatures to those from other calculations. Methods. For this purpose we solved the full non-LTE radiative-transfer problem for a gas consisting of hydrogen, helium and calcium. We used simple isobaric 1D slabs and began with isothermal models. Then we solved the radiativerelaxation problem and determined the radiative-equilibrium conditions within the whole slab. Results. By adding the calcium radiative losses, we found that these equilibrium temperatures are considerably lower than those obtained for a pure hydrogen gas. This is because the newly calculated CaII line losses appear to play a significant role in the energy balance, similar to chromospheric conditions. The equilibrium temperatures obtained span the range between 4400 - 9500 K, depending on the gas pressure and slab thickness.

Human African Trypanosomiasis causes cardiac rhythm disturbances through hitherto unknown mechanisms. It is known that the pr sence of such protozoan parasites or simply their supernatant has excitator y effects on isolated cardiomyocytes, seen as increased Ca 2+ wave occurrence. We investigated the theory that the protozoa are able to release a cath epsin L-like product into solution which is the initiator of such waves. Adult rat le ft ventricular cardiomyocytes were isolated in solution before [Ca ] was raised to physiological extracellular concentration. The cells were then exposed to pH c ontrolled samples of supernatant, with or without a known cathepsin L-li ke protease inhibitor (K11777), and all were subjected to population stud ies of wave incidence over 60 second timeframes. Results Baseline percentage of spontaneously waving cells i n mock extracellular solution was found to be significantly lower than with the p resence of Trypanosome supernatant. Addition of K11777 led to a significa nt reduction in spontaneity toward baseline. These results suggest that T. b. brucei produces a cathepsin Llike cysteine protease which causes increased incid e e of Ca 2+ waves.
Factors that Influence the Perceived Advantages and Relevance of Facebook as a Learning Tool: An Extension of the UTAUT.

Social media technologies are becoming a fundamental component of education. This study extends the Unified Theory of Acceptance and Use of Technology (UTAUT) to identify factors that influence the perceived advantages and relevance of Facebook as a learning tool. The proposed model is based on previous models of UTAUT. Constructs from previous models were used such as performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation and habit. Additionally, two new perspectives were added: perceived advantages and perceived relevance of Facebook as a social media platform. It provides some insights into students' behavioural intentions, and such an understanding can help faculty to examine their assumptions about the role of social media technologies in the teaching and learning process. The study participants were students enrolled in a Spanish public university. Data from 956 usable questionnaires were tested against the research model. Our results provide support to the model and reveal a good model fit. In light of these findings, implications for theory and practice are discussed.
Entanglement Entropy in Lifshitz Theories

We discuss and compute entanglement entropy (EE) in (1+1)-dimensional free Lifshitz scalar field theories with arbitrary dynamical exponents. We consider both the subinterval and periodic sublattices in the discretized theory as subsystems. In both cases, we are able to analytically demonstrate that the EE grows linearly as a function of the dynamical exponent. Furthermore, for the subinterval case, we determine that as the dynamical exponent increases, there is a crossover from an area law to a volume law. Lastly, we deform Lifshitz field theories with certain relevant operators and show that the EE decreases from the ultraviolet to the infrared fixed point, giving evidence for a possible c-theorem for deformed Lifshitz theories.
The Effect of Occlusal Loading on the Periodontal Tissues. A Literature Review. Part I – Occlusion and Periodontitis

The aim of this study was to review the literature concerning the association between occlusal loading and the presence and progression of periodontal diseases. The results of the work will be discussed in two parts. The first part of the study presents the latest research on the impact of occlusal disharmony on periodontal tissue changes during periodontitis. The second section reviews the literature on the relationship between the occlusal trauma and changes in the healthy periodontal tissues and formation of gingival recession. The results of some studies allow to conclude that occlusal interferences may correlate with periodontal tissue destruction during periodontitis and the presence of gingival recession, although some studies deny this findings. Hovever, despite these various reports assessing occlusion and the response of periodontal tissues it is noted that untreated abnormal occlusal contacts exacerbate periodontal diseases. Confirmed in research impact of occlusal adjustment on an improvement in periodontal parameters suggests the desirability of occlusive therapy in patients with periodontal diseases and the need a multidisciplinary approach to patients and their treatment team. The studies suggest occlusal therapy as an effective management of these pathologies. Therefore, a thorough diagnosis and comprehensive treatment, properly scheduled and carried out in cooperation with periodontists and prosthodontists, play an important role to achieve the intended therapeutic success (Dent. Med. Probl. 2015, 52, 2, 215–221).
Is it Easier to Escape from Low Pay in Urban Areas? Evidence from the UK

In this paper we compare periods of low pay employment between rural and urban areas in the UK. Using the British Household Panel Survey, we estimate the probability that a period of low pay employment will end allowing for a number of possible outcomes, namely to a "high pay" job, self-employment, unemployment and out of the labour force. The results show that there are statistically significant differences in the dynamics of low pay across urban and rural labour markets, particularly in terms of exits to high pay and out of the labour force. After controlling for different personal and job characteristics across markets, rural low pay durations are slightly longer on average, with a lower probability that rural workers will move to high pay. However, the results suggest that the most significant urban-rural differences in the typical low pay experience are concentrated among certain types of individuals, e.g. young workers, women without qualifications.
Bonding and structural changes in siderite at high pressure

Abstract Understanding the physical and chemical properties of carbonate minerals at extreme conditions is important for modeling the deep carbon cycle, because they represent likely hosts for carbon in the lower mantle. Previous high-pressure studies have identified a structural and electronic phase transition in siderite using X-ray diffraction and X-ray emission spectroscopy. The Fe end-member of the carbonate group, siderite (FeCO3), exhibits unique high-pressure behavior that we investigated using a combination of in situ Raman spectroscopy, synchrotron X-ray diffraction, and theoretical methods. In this Raman spectroscopy study, we observed the appearance of a new CO3 symmetric stretching mode at 20 cm−1 lower frequency beginning at approximately 46 GPa. This softening is due to the lengthening of the C-O bonds as a result of a combination of rotation and volume shrinkage of the FeO6 octahedra while siderite undergoes the isostructural volume collapse and electronic spin transition.
Transport of colloids in unsaturated porous media: Explaining large‐scale behavior based on pore‐scale mechanisms

We conducted column‐scale experiments to study the transport of colloids (latex particles and bacteriophage MS2) under water‐unsaturated conditions. The objective was to draw connections between observations at the pore scale and the results obtained from column‐scale experiments. The same system had been previously operated under saturated conditions to determine colloid collision efficiency. Breakthrough of colloids was first evaluated under unsaturated but steady water content conditions, with constant trickling flow. After monitoring the steady breakthrough of the colloids, the column was flushed with water at higher flow rate to increase the water content up to a saturated condition. Colloid breakthrough was monitored during the entire experiment, as water content increased. Colloid removal increases significantly with decreasing initial water saturation, reflecting retention at the air‐water interface and straining in thin‐water films. Colloid breakthrough occurs earlier than a conservative tracer even under unsaturated conditions, although the colloid concentrations are much lower than the tracer. After flushing at similar flow rates, there is increased colloid retention under unsaturated conditions even as the system approaches water saturation, indicating that additional removal is occurring, due possibly to the formation of colloidal clusters. These results can be explained to a great extent by pore‐scale observations of retention and remobilization mechanisms.
Job Satisfaction as a Reflection of Disposition: A Multiple Source Causal Analysis

Abstract Dispositional sources of job satisfaction have been the subject of recent research in the organizational sciences. Problems in much of this research, which limit the conclusions one can draw from the results, are discussed. This study makes a distinction between affective disposition, defined as the tendency to respond generally to the environment in an affect-based manner, and subjective well-being, the level of overall happiness and satisfaction an individual has with his or her life. Affective disposition was hypothesized to lead to subjective well-being, and subjective well-being and job satisfaction were hypothesized to be mutually causal. A causal model was tested employing two different sources of data: self-reports and "significant other" evaluations. This biangulation of sources of data and estimation of nonrecursive relationships removes some problems often assumed to plague results based on single-source data. Results indicated support for the overall hypothesized causal model and supported a dispositional influence on job attitudes. The influences are more complex than past research has suggested.
Walking and Jogging: Quantification of Muscle Activity of the Lower Extremities

Basmajian (1967) defined locomotion as “the translation of the centre of gravity through space along a path requiring the least expenditure of energy”. Taking as reference the centre of gravity (CG) of the body, it has been already established that the trajectory while walking or jogging follows a sinusoidal course (Inman 1968), with two vertical summits per stride (one cycle of locomotion). During locomotion, the movement of translation of the body is produced by the spatial angular movement of the lower extremities that shows support and non-support phases. The basic unit of measurement in gait analysis is the gait cycle (GC) or stride. The gait cycle is commonly divided into two phases: 1) stance phase, and 2) non-support phase. In walking, in the stance phase there are two periods of double support. In jogging cycle (JC) the phase of non support is composed of two float periods (when both feet are airborne) and between both periods there is one period of swing of the ipsilateral leg. Walking and jogging present differences at: 1) the velocity pattern, which is higher in jogging, as it implies joint movements of higher amplitude and speed; 2) the duration of cycles and of their respective phases; 3) the kinematics of: a) the peaks of the body CG trajectory (its amplitude and time of appearance), and b) of the joints, as there are wider angular joints displacements and different distribution of arches movements during cycle phases (Novacheck, 1998); 4) the kinetic: a) amplitude, duration, and evolution of the ground reaction force (Mann, 1982), external moments of force, and muscle power (Winter, 1983a and 1983b); b) misalignment of CG between the segments of the leg and of the upper part of the body (head, trunk, and arms); c) inertia; and 5) the mechanisms for saving energy structures (Cavagna & Kaneko, 1977; van Ingen Schenau et al., 1987). Several studies have compared the muscle activity of the legs during walking and jogging or running. In the works of Mann & Hagy (1980), and Mann (1982), the subjects were trained athletes, and in the work of Ounpuu (1994) they were children. In all the above-mentioned papers the muscle activity was recorded from only one leg, and the muscular activity was qualitatively described rather than quantified. Nilsson et al. (1985) and Gazendam and Hof (2007) quantified the profiles of averaged rectified EMGs at different speeds of locomotion and mode of progression in humans on motor-driven treadmill.
