Carbon literacy is a key medium to enhance the understanding of an individual's consciousness on reducing carbon emissions in the atmosphere towards addressing the issue of global warming and climate change. This article aims to identify the level of carbon literacy among lower secondary schools students in Malaysia. The study involved 463 Form 2 students from eleven schools in the Federal Territory of Putrajaya. The schools were selected using a systematic sampling and respondents were selected using a simple random sampling. Questionnaire Likert scale of 1 to 5 were used as a research instrument. Carbon literacy variable studies include four variables, namely the carbon footprint knowledge, low carbon attitudes, carbon literate value and low carbon practices. Carbon footprint knowledge variables consist of six sub variables: energy saving, recycling, mode of travel, carbon footprint, air pollution and the greenhouse effect. As for the variables of carbon literacy attitude, sub variables consist of energy saving, recycling and mode of travel followed by sub variables of carbon literacy value of the individual and the society. And for the practice of low-carbon, it consists of sub variables, namely energy saving, recycling and mode of travel. Result showed that the questionnaire reliability obtained with Cronbach alpha values for each variable was greater than 0.7. Meanwhile, the level of knowledge of the carbon footprint, low-carbon attitudes, values and practices of low-carbon literacy carbon is at a high level as a whole except for the variable sub knowledge that air pollution is moderate. These findings demonstrated that carbon literacy level of students at the high level and the situation are clear implications of a positive target inapplicable in Federal Territory of Putrajaya towards a Low Carbon City and Green City in 2025.

The use of incandescent bulbs by the majority of building occupants in Nigeria has complemented high cost of electrical energy consumption and this has informed prevalence of different types of energy efficient lighting bulbs. The study, therefore, identified and examined types of lighting bulbs used, assessed the rate of use of energy efficient bulbs in selected residential buildings and examined factors influencing its use. The study was carried out in Ife Central Local Government Area of Osun State, Nigeria. Residential settlements in core wards in the study area were considered and four wards in the core zone of the Local Government were randomly selected from the total of eleven while data collection was done with the use of primary and secondary data techniques. Simple random sampling technique was used to select 5% sample size from the entire population and systematic sampling procedure was further employed by selecting every 10th building in the direction of movement which indicated selection of 123 houses. A total of 123 structured questionnaires were administered on the respondents on issues associated with the use of lighting bulbs. Data collected were analysed by both descriptive and inferential statistical techniques. The study found that 90.53% and 72.63% of the respondents used incandescent and energy saving bulbs respectively; variation existed in the wattages of different brands of energy saving and non-energy saving bulbs used in the selected buildings: A major proportion of the respondents used an average number of 1-5 lighting bulbs in buildings and its spaces therein; while quality and cost-saving benefit, energy saving benefit and durability of bulb influenced the choice of fluorescent tubes, compact fluorescent bulbs and light emitting diodes with a mean score value of 2.20, 2.29 and 2.85 respectively. In view of the need to enhance visual performance and comfort of buildings and its occupants respectively, efforts must be made by government to ensure that consumers awareness and enlightenment be increased on the types of lighting bulbs to procure and there is also need to strengthen mechanisms through the importation and sales of energy efficient bulbs only so as to enhance its cost-saving and environment–related benefits amongst others.

The aim of the study is to investigate and compare the correlation between energy consumption, air pollution and economic growth in China and the USA. Both countries are powerful economic countries in the world, thus we attempt to know whether energy consumption and air pollution vary as the economy develops. The data for the research spanning from 1970 to 2014 was gathered from an indicator of the World Bank. The time span was decided due to the data availability of both countries. To examine the long-run equilibrium relationship, there was performed the ARDL bound test. Results of unit root indicated that all the variables were integrated of order one. In the case of the ARDL bound test, the values of F-statistics exceeded the upper bound value, which means they are statistically significant. The estimation results substantiated the positive coefficient of energy consumption at the 1% significance level in China, implying that air pollution can increase as the energy consumption rises in China. However, the empirical results of the USA were exactly on the contrary. The outcomes of the CUSUM and CUSUMSQ tests revealed that all coefficients in both the short- and long-run models were stable. Based on the above analysis, the study suggests that China should adopt innovation and environmentally friendly modern technologies. Specifically, China ought to inspire and motivate energy saving and low-carbon research innovations, energy saving industries, green investment and carbon sequester technologies as well as public environmental awareness creations to mitigate environmental deterioration and climate change.

BACKGROUND: This paper deals with territorial distribution of the alcohol and drug addictions mortality at a level of the districts of the Slovak Republic. AIM: The aim of the paper is to explore the relations within the administrative territorial division of the Slovak Republic, that is, between the individual districts and hence, to reveal possibly hidden relation in alcohol and drug mortality. METHODS: The analysis is divided and executed into the two fragments – one belongs to the female sex, the other one belongs to the male sex. The standardised mortality rate is computed according to a sequence of the mathematical relations. The Euclidean distance is employed to compute the similarity within each pair of a whole data set. The cluster analysis examines is performed. The clusters are created by means of the mutual distances of the districts. The data is collected from the database of the Statistical Office of the Slovak Republic for all the districts of the Slovak Republic. The covered time span begins in the year 1996 and ends in the year 2015. RESULTS: The most substantial point is that the Slovak Republic possesses the regional disparities in a field of mortality expressed by the standardised mortality rate computed particularly for the diagnoses assigned to the alcohol and drug addictions at a considerably high level. However, the female sex and the male sex have the different outcome. The Bratislava III District keeps absolutely the most extreme position. It forms an own cluster for the both sexes too. The Topoľčany District bears a similar extreme position from a point of view of the male sex. All the Bratislava districts keep their mutual notable dissimilarity. Contrariwise, evaluation of a development of the regional disparities among the districts looks like notably heterogeneously. CONCLUSIONS: There are considerable regional discrepancies throughout the districts of the Slovak Republic. Hence, it is necessary to create a common platform how to proceed with the solution of this issue.

The negative and persistent impact of the human factor on the statistics of aviation accidents and serious incidents makes proactive studies of the attitude of “front line” aviation operators (air traffic controllers, flight crewmembers) to dangerous actions or professional conditions as a key component of the current paradigm of ICAO safety concept. This “attitude” is determined through the indicators of the influence of the human factor on decision-making, which also include the systems of preferences of air traffic controllers on the indicators and characteristics of professional activity, illustrating both the individual perception of potential risks and dangers, and the peculiarities of generalized group thinking that have developed in a particular society. Preference systems are an ordered (ranked) series of n = 21 errors: from the most dangerous to the least dangerous and characterize only the danger preference of one error over another. The degree of this preference is determined only by the difference in the ranks of the errors and does not answer the question of how much time one error is more dangerous in relation to another. The differential method for identifying the comparative danger of errors, as well as the multistep technology for identifying and filtering out marginal opinions were applied. From the initial sample of m = 37 professional air traffic controllers, two subgroups mB=20 and mG=7 people were identified with statisti-cally significant at a high level of significance within the group consistency of opinions a = 1%. Nonpara-metric optimization of the corresponding group preference systems resulted in Kemeny’s medians, in which the related (middle) ranks were missing. Based on these medians, weighted coefficients of error hazards were determined by the mathematical prioritization method. It is substantiated that with the ac-cepted accuracy of calculations, the results obtained at the second iteration of this method are more ac-ceptable. The values of the error hazard coefficients, together with their ranks established in the preference systems, allow a more complete quantitative and qualitative analysis of the attitude of both individual air traffic controllers and their professional groups to hazardous actions or conditions.
