Abstract

Purpose

Teachers can be regarded as key figures in climate change education (CCE). Therefore, the purpose of this study is assessment of Iranian lower secondary teachers? level of knowledge, attitudes and practices toward CCE in a less-touched-upon context.

Design/methodology/approach

The present study used a cross-sectional survey design, which used a specially designed questionnaire administered in ten high schools (five boys’ and five girls’ lower secondary schools). A sample of 108 lower secondary school teachers was selected through a multistage stratified random sampling technique. The gender structure of the sample was 48.1 per cent male and 51.9 per cent female subjects. To determine the status of teachers’ knowledge, attitudes and practices, the obtained quantitative data were classified into three categories on a scale of 100 per cent: good status (more than 75 per cent), moderate status (50-75 per cent) and weak status (less than 50 per cent).

Findings

The findings revealed that the involved teachers were equipped with an appropriate knowledge, i.e. 22.2 per cent good and 52.8 per cent moderate levels of knowledge. Furthermore, the subjects’ level of attitude was moderate (44.5 per cent); however, their level of practice was weak (52.8 per cent). In terms of gender, male subjects’ knowledge and attitude levels were higher than those of female subjects. However, female subjects reported higher levels of practice in comparison with male subjects. Overall, the results of this study highlighted the necessity of improving lower secondary teachers’ CCE in general and of the level of their attitudes and practices in particular.

Originality/value

The present study sheds more light on the change management and environmental education within the Iranian context. The results of this study accentuate the necessity of presenting more CCE programs for teachers. Furthermore, curriculum planners can take advantage of the obtained results to carry out curriculum reforms.

Abstract

Purpose

Strategic planning is the best tool for managers seeking an informed presence and participation in the market without surrendering to changes. Strategic planning enables managers to achieve their organizational goals and objectives. Hospital goals, such as improving service quality and increasing patient satisfaction cannot be achieved if agreed strategies are not implemented. The purpose of this paper is to investigate the factors affecting strategic plan implementation in one teaching hospital using interpretive structural modeling (ISM).

Design/methodology/approach

The authors used a descriptive study involving experts and senior managers; 16 were selected as the study sample using a purposive sampling method. Data were collected using a questionnaire designed and prepared based on previous studies. Data were analyzed using ISM.

Findings

Five main factors affected strategic plan implementation. Although all five variables and factors are top level, “senior manager awareness and participation in the strategic planning process” and “creating and maintaining team participation in the strategic planning process” had maximum drive power. “Organizational structure effects on the strategic planning process” and “Organizational culture effects on the strategic planning process” had maximum dependence power.

Practical implications

Identifying factors affecting strategic plan implementation is a basis for healthcare quality improvement by analyzing the relationship among factors and overcoming the barriers.

Originality/value

The authors used ISM to analyze the relationship between factors affecting strategic plan implementation.

Abstract

Purpose

This paper aims to examine the investigations made on the corrosion behaviour of magnesium (Mg) substrate electrodeposited using different nano-materials.

Design/methodology/approach

This study uses nano-materials such as those of reduced graphene oxide (r-GO), titanium-di-oxide (TiO2) and also r-GO/TiO2 nano-composites (dispersed through ultra-sonication process) at 3-min time interval. Crystalline nature of synthesized TiO2 is studied through X-ray diffraction and its pore volume is measured to be approximately 0.1851ccg-1 by Brunauer Emmett Teller analysis.

Findings

Surface morphology of the developed set of specimens inspected through scanning electron microscopy and energy dispersive spectroscopy establishes a clean surface coating and further witnesses for only minimal defects. Electrochemical behaviour of the developed coating is studied exhaustively using Tafel polarization and electrochemical impedance spectroscopy in 0.1 M Na2SO4 solution.

Originality/value

Incremental corrosion resistance exhibited by developed composite coating owes to the factors viz. chemical stability and hydrophobic tendency of TiO2 and r-GO; these known engineering facts resist the flow of ions into the corrosive media and thereby reduce the rate of corrosion.

Abstract

Purpose

The purpose of this paper is to recommend a validated numerical model for simulation the flue gases heat recovery recuperators. Due to fulfill of this demand, the influences of ash fouling characteristics during the transient/steady-state simulation and optimization of a 3D complex heat exchanger equipped with inner plain fins and side plate fins are studied.

Design/methodology/approach

For the particle dispersion modeling, the discrete phase model is applied and the flow field has been solved using SIMPLE algorithm.

Findings

According to obtained results, for the recuperator equipped with combine inner plain and side plate fins, determination of ash fouling characteristics is really important, effective and determinative. It is clear that by underestimating the ash fouling characteristics, the achieved results are wrong and different with reality.

Originality/value

Finally, the configuration with inner plain fins with characteristics of: di =5 mm, do = 6 mm, dg = 2 mm, dk = 3 mm and NIPFT = 9 and side plate fins with characteristics of: TF = 3 mm, PF = 19 mm, NSPF = 17·2 = 34, WF = 10 mm, HF = 25 mm, LF = 24 mm and ß = 0° is introduced as the optimum model with the best performance among all studied configurations.
