Factors affecting the sustainability of educational changes: A mixed method research

Abstract The aim of this study is to determine factors affecting the sustainability of educational changes. With this purpose in mind, exploratory sequential mixed methods design was used. During the first phase of the study, 18 teachers and school administrators were interviewed. In the second phase, a questionnaire was administered to 398 teachers and school administrators and collected data were analysed by Ordinal Logistic Regression Analysis. Results of the study revealed that the sustainability of educational changes that occurred in the Turkish educational system was generally poor. Research results also indicated that the four factors identified had statistically significant effect on the sustainability of educational changes.
Morphometric study of accessions of Sesamum indicum L. collected from Nigeria

Sesamum (Sesamum indicum L.), is a very beneficial plant with manifold implementation in human life hence the identification of different species on the basis of morphological basis is indeed a need especially in less developed parts of the world. Morphometric studies of 12 accessions were carried out in order to find out characters which may be used for the delimitation of the accessions. Both quantitative and qualitative characteristics of the leaves, stems, flowers, stipule, node, fruit pods and growth type were studied and coded. Numerical analysis of these character data using cluster analysis – average linkage, single linkage, complete linkage and centroid method delimit the 12 accessions into five cluster groups which conform to the results of the morphological analysis. The results of these morphological variability analyses may set the foundation to detect promising accessions for mapping out future breeding schemes and also will be helpful for other researchers working on other aspects such as medicinal or nutritive consumption of different accessions of this multi-purpose crop. Key words: Morphology, Sesamum indicum, accessions, taxonomy.
Distribution of heavy metals in the vicinity of a nuclear power plant, east coast of India: with emphasis on copper concentration and primary productivity

Seawater samples collected in the vicinity of MAPS (Madras Atomic Power Station) from 17 stations covering an area of 4 km were analysed for distribution of heavy metals viz. iron, copper, cadmium and mercury. Mercury was analysed by cold vapor Atomic Absorption Spectrometry (AAS) and the other heavy metals by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Water samples were found to have heavy metals such as Fe (26-85 μg l), Cu (0.05-5.1μgl; Cd (0.5-1.7 μg l) and Hg (0.03-1.5 μg l). Samples from the power plant cooling system and condenser outfall were specifically analysed for copper and primary production. Copper concentrations were in the range 1 – 2.2 μg l. Primary productivity was low on passing through the power plant cooling circuit. However, it was found to recover once the effluent mixed with the ambient sea. Present study infers that heavy metal concentrations in the vicinity of the power station outfall are comparable to unpolluted pelagic waters of the Bay.
EFFECTS OF INTEGRATION AND UPSTREAM MARKET STRUCTURES

This paper shows that vertical integration can lower equilibrium prices in a downstream market, whether an upstream market is monopolized or not. However, there is not necessarily a trade-off between competitiveness and market efficiency. In fact, the integration enables an upstream monopolist to exploit leverage in a market and to exclude a rival from that market, but firms other than a monopolist can not drive a rival from a market. Thus, upstream market structure matters. It will be shown when integration promotes efficiency and when it does not, and also that situations of “keiretsu”, found in Japanese industries, emerge.

Sensations of Chinese Ametropia Patients under Laser-Assisted Keratomileusis Surgical Techniques

Purpose: To investigate the sensations experienced by Chinese patients during refractive surgery including the laser in situ keratomileusis (LASIK), Epi-Lasik, and Sub-Bowman keratomileusis (SBK) techniques. A prospective, randomized, and self-matched clinical study was conducted. Methods: The participants included 44 men and 58 women aged 16 to 47 years old (mean 24.3±0.6 years) who underwent bilateral refractive surgery. Data were collected by using a standardized questionnaire regarding intraoperative experiences including light perception, perception of the green fixation light, pain, fear, and so on. Results: A higher proportion of patients experienced temporary loss of light perception in the LASIK group compared with the Epi-Lasik and SBK groups (97% vs. 92% vs. 73%; χ =0.0072, p<0.05). Moreover, 71 patients were frightened by their intraoperative experiences [20 Epi-Lasik patients (71%); 23 LASIK patients (68%); 28 SBK patients (70%)]. These patients were mostly younger, aged ≤ 20 years (χ =0.0182, p<0.05). Moreover, the younger age group was significantly associated with the higher level of fear (χ =0.0011, p<0.05). Patients included in the group who felt pain with a mean duration of surgery ranging from five to 10 minutes (8.471±1.566) were significantly less in number compared with those who did not feel pain (7.100±1.820) (χ =0.0154, p<0.05). Patients also saw colors and movement, but the differences were not significant among the techniques. Patients experienced various visual sensations. Conclusion: Younger age and relatively longer surgical durations were found to be the risk factors for the visual sensations of fear and pain during surgery. Preoperative counseling is an important factor in preparing patients for such visual experiences.
Shear bond strength of orthodontic brackets bonded with conventional and fluoride-releasing bonding materials with and without adhesive application

Objective: To evaluate the shear bond strength of a composite resin and a compomer for bonding brackets with and without adhesive application. Methods: Eighty-eight extracted human premolars were divided into four groups: Control group resin (CGR), in which conventional resin Transbond™ XT Light Cure (3M Unitek™, USA) was used to bond the brackets with prior application of the adhesive; Experimental group resin (EGR), in which conventional resin Transbond™ XT Light Cure was used without prior adhesive application; Control group compomer (CGC), in which compomer Transbond™ Plus Color Change (3M Unitek™, USA) was used with prior adhesive application; and Experimental group compomer (EGC), in which compomer Transbond™ Plus Color Change was used without prior adhesive application. A shear debond test was performed using an EMIC machine and results were analyzed by ANOVA and post hoc Tukey multiple comparison test. Results: No statically significant difference was found between control and experimental groups for the conventional resin and compomer (P=0.802 and P=0.837). The compomer presented lower shear bond values than conventional resin (P=0.004 and P=0.003). Conclusion: Considering the shear bond strength, the four groups evaluated presented adequate values, irrespective of using adhesive or not.
Physical Interpretation of the Spectral Radiative Signature in the Transition Zone Between Cloud-Free and Cloudy Regions

Abstract. One-second-resolution zenith radiance measurements from the Atmospheric Radiation Measurement program's new shortwave spectrometer (SWS) provide a unique opportunity to analyze the transition zone between cloudy and cloud-free air, which has considerable bearing on the aerosol indirect effect. In the transition zone, we find a remarkable linear relationship between the sum and difference of radiances at 870 and 1640 nm wavelengths. The intercept of the relationship is determined primarily by aerosol properties, and the slope by cloud properties. We then show that this linearity can be predicted from simple theoretical considerations and furthermore that it supports the hypothesis of inhomogeneous mixing, whereby optical depth increases as a cloud is approached but the effective drop size remains unchanged.
Electric and magnetic radial diffusion coefficients using the Van Allen probes data

ULF waves are a common occurrence in the inner magnetosphere and they contribute to particle motion, significantly, at times. We used the magnetic and the electric field data from the Electric and Magnetic Field Instrument Suite and Integrated Sciences (EMFISIS) and the Electric Field and Waves instruments (EFW) on board the Van Allen Probes to estimate the ULF wave power in the compressional component of the magnetic field and the azimuthal component of the electric field, respectively. Using L∗, Kp, and magnetic local time (MLT) as parameters, we conclude that the noon sector contains higher ULF Pc‐5 wave power compared with the other MLT sectors. The dawn, dusk, and midnight sectors have no statistically significant difference between them. The drift‐averaged power spectral densities are used to derive the magnetic and the electric component of the radial diffusion coefficient. Both components exhibit little to no energy dependence, resulting in simple analytic models for both components. More importantly, the electric component is larger than the magnetic component by one to two orders of magnitude for almost all L∗ and Kp; thus, the electric field perturbations are more effective in driving radial diffusion of charged particles in the inner magnetosphere. We also present a comparison of the Van Allen Probes radial diffusion coefficients, including the error estimates, with some of the previous published results. This allows us to gauge the large amount of uncertainty present in such estimates.
Aggressiveness of Phytophthora boehmeriae and P. capsici isolates from India on hot pepper (Capsicum annum L.)

Phytophthora boehmeriae was reported as a dominant pathogen responsible for a severe foliar blight on hot pepper for the first time in India during 2011 and 2012 in Karnataka and Tamil Nadu states of India in addition to P. capsici. In the present study, four susceptible parental lines (Arka lohit,  PI 201232, Yolo Wonder, PB 602) and 28 germplasm collections (IIHR 4519 to IIHR 4549, and IIHR 3449) maintained at Indian Institute of Horticultural Research were screened against Phytophthora isolates using detached leaf technique. The results showed that P. boehmeriae were highly aggressive on all chilli germplasm lines (P < 0.01) when compared to P. capsici isolates and no germplasm line exhibited tolerance. Thus, the studies indicated that P. boehmeriae may emerge as most destructive pathogen on chilies which warrants a vigil on this pathogen.
Do Procedures Matter in Fairness Allocations? Experimental Evidence in Mixed Gender Pairings

Does the procedure of entitlement affect fairness perceptions? We use a dictator game to study the question in mixed gender pairs. In our experiments, we vary the process of entitlement across treatments. Allocators in our dictator game can inherit an amount without any effort, earn an amount with effort, or inherit an amount earned by a randomly matched partner's effort. We find subjects allocate lower amounts to their paired partners when they are dividing an amount that has been earned through their own effort and allocate relatively higher amounts when dividing an amount that has been earned through the paired member's real effort. Results also suggest that female proposers are more sensitive towards variations in entitlement processes.
Wind waves in the Black Sea: results of a hindcast study

Abstract. In this study we describe the wind wave fields in the Black Sea. The general aims of the work were the estimation of statistical wave parameters and the assessment of interannual and seasonal wave parameter variability. The domain of this study was the entire Black Sea. Wave parameters were calculated by means of the SWAN wave model on a 5 × 5 km rectangular grid. Initial conditions (wind speed and direction) for the period between 1949 and 2010 were derived from the NCEP/NCAR reanalysis. According to our calculations the average significant wave height on the Black Sea does not exceed 0.7 m. Areas of most significant heavy sea are the southwestern and the northeastern parts of the sea as expressed in the spatial distribution of significant wave heights, wave lengths and periods. Besides, long-term annual variations of wave parameters were estimated. Thus, linear trends of the annual total duration of storms and of their quantity are nearly stable over the hindcast period. However, an intensification of storm activity is observed in the 1960s–1970s.
An empirical rule for extended range prediction of duration of Indian summer monsoon breaks

Prediction of the duration of the Indian summer monsoon breaks is highly desirable. It will help in planning water resource management, sowing and harvesting. Applicability of the recently discovered regime transition rules for the Lorenz model in predicting the duration of monsoon breaks, is explored in this paper. Using several indices of the observed summer monsoon intraseasonal oscillation (ISO), it is shown that the peak anomaly in an active regime can be used as a predictor for the duration of the subsequent break spell. It is also found that the average growth rate around the threshold to an active condition can be used as a predictor of the peak anomaly in the active spell. Average growth around the threshold to an active condition can give useful prediction of the duration of the following break, on an average, about 23 days (38 days) in advance of its commencement (end).

Factors Affecting Public Transport in Petaling Jaya, Malaysia: An Extension of the Theory of Planned Behaviour

In order to understand travellers’ willingness to use the train in Petaling Jaya, this study adds four predictors situational factors, trust, novelty seeking and external influence to the existing model of theory of planned behaviour (TPB). The study collected research data from employees in Petaling Jaya, Malaysia, resulting in an effective data of 400 participants. Results indicate that attitude, perceived behavioural control, and subjective norm are found to have positive effects on the behavioural intention of taking the train. Furthermore, novelty seeking, trust, and external influence also have positive influences on attitude, the three antecedents of the intention, and the subjective norm in taking the train respectively. While situational factors were found to have a negative influence on attitude towards behavioural intention to take the train.
MASS-LOSS RATES OF OH/IR STARS

We compare mass-loss rates of OH/IR stars obtained from radio observations with those derived from the dust radiative transfer models and IR observations. We collect radio observational data of OH maser and CO line emission sources for a sample of 1533 OH/IR stars listed in Suh & Kwon (2011). For 1259 OH maser, 76 CO(J=1-0), and 55 CO(J=2-1) emission sources, we compile data of the expansion velocity and mass-loss rate. We use a dust radiative transfer model for the dust shell to calculate the mass-loss rate as well as the IR color indices. The observed mass-loss rates are in the range predicted by the theoretical dust shell models corresponding to _ M = 10 i8 Mfl=yr - 10 i4 Mfl=yr. We flnd that the dust model using a simple mixture of amorphous silicate and amorphous Al2O3 (20% by mass) grains can explain the observations fairly well. The results indicate that the dust radiative transfer models for IR observations generally agree with the radio observations. For high mass-loss rate OH/IR stars, the mass-loss rates obtained from radio observations are underestimated compared to the mass-loss rates derived from the dust shell models. This could be because photon momentum transfer to the gas shell is not possible for the physical condition of high mass-loss rates. Alternative explanations could be the efiects of difierent dust-to-gas ratios and/or a superwind.
Identification of Competencies for Professionals in Open Innovation Teams

In the open innovation management literature, it is widely acknowledged that individuals play a crucial role in collaborative knowledge creation processes. However, the literature tends not to explore the human side of open innovation teams. The present article therefore examines the competencies that professionals need for working in open innovation teams (specific but not necessarily unique to open innovation) and to cope with the challenges they face. A qualitative study consisting of explorative interviews and focus group discussions was conducted, resulting in a competence profile for open innovation professionals. The profile adds a new perspective to the field of open innovation management by focusing on how individuals involved in open innovation teams can enhance open innovation success. It reveals, among other things, how professionals can generate new knowledge, build trust, and deal with low reciprocal commitment in open innovation teams. Especially, brokering solutions and being socially competent seem to be important for open innovation professionals. Companies should focus on these competencies when supporting their professionals in open innovation teams.
Exploring the Roles of Social Structures, Employees’ Green IS Orientation and Employee Commitment in Routinization of Green IS Practices in Organizations

There is growing recognition of the role of Green IS practices (GISP) in mitigating environmental problems. Research indicates that in addition to contributing towards sustainability, GISP has the potential to contribute to organization’s bottom line and improve stakeholders’ image of the organization. Consequently, there is an upward trend of organizations adopting GISP. However, to realize fully the benefits of GISP, it must be engrained and entrenched into the organizational processes, i.e., GISP needs to be routinized. So far, research on GISP has been limited to one shot adoption decisions while ignoring the process of routinization. Drawing from the literature on structuration and internal market orientation, we examine the impact of organizational meta-structures and internal market Green IS orientation on employee commitment and its subsequent impact on routinization of GISP. Furthermore, addressing the inconsistent findings in the literature, this paper also examines the impact of routinization on tangible and intangible organizational benefits.
EFFECTS OF VISUAL IMAGES IN HEALTH MESSAGE FRAMING

This study examined the effectiveness of visual images and message frames in communicating health risks. Specifically, an experiment (N = 95) was conducted to explore the effectiveness of message frames and message formats on persuasiveness (attitude toward the message, perceived effectiveness, and behavioral intention), fear, and cognitive processing by utilizing a 2 (message frames: gain vs. loss) × 2 (message formats: verbal vs. visual) × 2 (health issues: dental flossing vs. sunscreen use) mixed factorial design. Results indicate that significant message frames × message formats interaction effects on fear and persuasiveness were found with the negative visual conditions generating more fear and persuasiveness. The effects of the message formats on cognitive processing (systematic or heuristic) were not significant. Mediation tests showed that fear mediated the relationship between message format and persuasion. These results suggest that increased fear as generated by negative visual images led to more persuasion rather than increased processing of the messages. Implications and limitations of this study, and the directions for future study were discussed.
Possibilities of using image analysis to estimate the nitrogen nutrition status of apple trees

Precise timing and rate of nitrogen (N) fertilizer application play a major role for crop yield and quality. Prediction of N requirements is necessary for efficient utilization of nitrogen fertilizers. A user-friendly method for estimating foliar nitrogen concentration, based on an analysis of leaf blade colour, was developed in the study. Apple tree (Malus domestica Borkh.) was used as a model species for the validation of the proposed method. Digital recording of adaxial leaf surface was performed using a flatbed scanner. The acquired images were analysed to obtain average values of basic colours: red, green and blue (RGB). Analyses of the relationships between N concentration in the leaves, leaf greenness indices (determined with SPAD-502 and CCM-200 meters) and RGB colour components were performed. The best fitted models were: a multiple regression model based on RGB primary colour values and a model that included the values of the red and blue colours as well as a parameter describing the age of the leaf. The performed tests showed that the analysis of scanned images provided a more precise determination of leaf nitrogen content in apple trees compared to the measurements conducted with leaf greenness meters.
