This study presents the spatial analysis of the rainfall data over Peninsular Malaysia. 70 rainfall stations were utilized in this study. Due to the limited number of rainfall stations, the Ordinary Kriging method which is one of the techniques in Spatial Interpolation was used to estimate the values of the rainfall data and to map their spatial distribution. This spatial analysis was analysed according to the two indices that describe the wet events and another two indices that characterize dry conditions. Large areas at the east experienced high rainfall intensity compared to the areas in the west, northwest and southwest. The small value that has been obtained in Aridity Intensity Index (AII) reflects that the high amount of rainfall in the eastern areas is not contributed by low-intensity events (less than 25th percentile). In terms of number of consecutive dry days, Northwestern areas in Peninsular Malaysia recorded the highest value. This finding explains the occurrence of a large number of floods and soil erosions in the eastern areas.

Landscape management requires spatially interpolated data, whose outcomes are strictly related to models and geostatistical parameters adopted. This paper aimed to implement and compare different spatial interpolation algorithms, both geostatistical and deterministic, of rainfall data in New Zealand. The spatial interpolation techniques used to produce finer-scale monthly rainfall maps were inverse distance weighting (IDW), ordinary kriging (OK), kriging with external drift (KED), and ordinary cokriging (COK). Their performance was assessed by the cross-validation and visual examination of the produced maps. The results of the cross-validation clearly evidenced the usefulness of kriging in the spatial interpolation of rainfall data, with geostatistical methods outperforming IDW. Results from the application of different algorithms provided some insights in terms of strengths and weaknesses and the applicability of the deterministic and geostatistical methods to monthly rainfall. Based on the RMSE values, the KED showed the highest values only in April, whereas COK was the most accurate interpolator for the other 11 months. By contrast, considering the MAE, the KED showed the highest values in April, May, June and July, while the highest values have been detected for the COK in the other months. According to these results, COK has been identified as the best method for interpolating rainfall distribution in New Zealand for almost all months. Moreover, the cross-validation highlights how the COK was the interpolator with the best least bias and scatter in the cross-validation test, with the smallest errors.

The Government

The government is very concerned about issues related to schooling because the results of education today will shape our generation in the future. In this regard, the government takes seriously the aspect of national education and implements various initiatives to improve the effectiveness and excellence of schools through one of the aspects contained in the strategic thrust of the Malaysian Education Development Plan (PPPM) 2013-2025 which is focused on the quality of student academic achievement as the main agenda of education reform. Therefore, in an effort to improve and enhance work performance among teachers, there are related issues that need to be emphasized. Teacher job performance gaps are examined and given emphasis from the aspect of job satisfaction, Therefore, this study aims to identify the relationship between job satisfaction factors and teacher job performance. The population of this study consisted of teachers at Sekolah Menengah Kebangsaan (SMK) in the education sector in the northern region, Peninsular Malaysia. However, for this study, the focus is given to the two locations of the states involved, are Perlis and Kedah. This location was chosen because the schools involved in this study are under one education system that implements the same policies and policies and the implementation of curricular and co-curricular activities is also the same. In fact, the schools involved in this study also received allocations and financial assistance in almost the same amount for the whole country (Ministry of National Education, MOE). For research purposes, this study used the questionnaire distribution method. While the process to analyze the data is using Statistical Packages for Social Science (SPSS) Version 24. The results of the analysis found that job satisfaction has a significant positive relationship with teacher work performance.

Rainfall data are the most significant values in hydrology and climatology modelling. However, the datasets are prone to missing values due to various issues. This study aspires to impute the rainfall missing values by using various imputation method such as Replace by Mean, Nearest Neighbor, Random Forest, Non-linear Interactive Partial Least-Square (NIPALS) and Markov Chain Monte Carlo (MCMC). Daily rainfall datasets from 48 rainfall stations across east-coast Peninsular Malaysia were used in this study. The dataset were then fed into Multiple Linear Regression (MLR) model. The performance of abovementioned methods were evaluated using Root Mean Square Method (RMSE), Mean Absolute Error (MAE) and Nash-Sutcliffe Efficiency Coefficient (CE). The experimental results showed that RF coupled with MLR (RF-MLR) approach was attained as more fitting for satisfying the missing data in east-coast Peninsular Malaysia.

The Standardized Precipitation Index

Drought is an extended period when a region notes a deficiency in its water supply. The Standardized Precipitation Index (SPI) method was used in this study to analyze drought. Northern region of Bangladesh was the area of study. Monthly rainfall data of northern region of Bangladesh was obtained from the Meteorological Department of Bangladesh. Obtained rainfall data was from 1991 to 2011 and values from 2012 to 2026 were generated using Markov model. Then SPI values from 1991 to 2026 were calculated by using SPI formula for analyzing drought. Analysis with SPI method showed that droughts in northern region of Bangladesh varied from moderately dry to severely dry conditions and it may vary from moderately dry to severely dry conditions normally in future but in some cases extreme drought may also take place. From the study, it is observed that the northern region of Bangladesh has already experienced severe drought in 1991, 1992, 1994, 1995, 1997, 1998, 2000, 2003, 2005, 2007, 2009 and 2010. The region may experience severe drought in 2012, 2015, 2016, 2018, 2019, 2021, 2022, 2023, 2024, 2025 and 2026 and extreme drought in 2012, 2014, 2016, 2023 and 2024. J. Environ.

Purpose The purpose of this study was to examine the effects of soft skill integration in the curriculum on quality of college life of diploma business students in Malaysian private higher educational institutions. Design/methodology/approach Descriptive quantitative survey research was used to assess the views and relationship between variables from 429 business students in Peninsular Malaysia. The adapted self-administered questionnaires were distributed through stratified random sampling method. Descriptive analysis, correlation and regression analysis were used in the findings. Findings The results advocated significant influence from soft skill integration on quality of college life. Soft skill integration in critical thinking and problem solving especially has significant positive influence on quality of college life in all the aspects from academic, social and also facilities. Research limitations/implications Generalizability of the research as it was conducted in the northern region of Peninsular Malaysia only. It was also limited by subjectivity bias of the students who responded to the questionnaire. Practical implications The implication of this study was that it serves as an evidence-based information of soft skill integration and effects on college quality. In this way, it provides an empirical reference to the authorities for better guidelines, evaluation, control and development in the curriculum, delivery approaches, co-curriculum, campus environment or facilities. Social implications Local education in particular is closely linked to the neighboring community and also dependent on the socio-economic needs of the state or region. According to Kayrooz and Parker (2010), greater engagement with local issues and higher local autonomy for spending could lead to greater effectiveness and efficiencies. Originality/value The study was a pioneering research in the context of Malaysian private higher education, guided by Devadason et al.’s (2010) soft skill integration study in Malaysian public higher education, plus Sirgy et al.’s (2007) study on quality of college life.

Purpose The purpose of this paper is to examine the structural relationships between the job itself (i.e. job characteristics), employee well-being and job performance in light of the new administrative reform called the Government Transformation Program in Malaysia that stresses on measurable performance outputs. Design/methodology/approach A total of 208 public sector employees from various public agencies and departments in the northern region of Peninsular Malaysia were surveyed. Some of the agencies that took part in the study include state departments, the fishery department, agriculture-related agencies and the rural development agency. Findings The authors observed that feedback positively influenced employee well-being, which served as a significant mediator in the relationship between feedback and job performance. The results indicated that 26.4 percent of the variance that explained employee well-being was accounted for by the different characteristics of a job. The authors also demonstrated that employee well-being accounted for 41.8 percent of job performance. Research limitations/implications The authors recommended that public sector managers consider the element of feedback and enhance employee well-being to improve job performance. Originality/value This study offers an insight into the effect of perceived changes in the job itself on employee well-being and subsequent job performance in light of government reforms.

The inconsistency in inter-seasonal rainfall due to climate change will cause a different pattern in the rainfall characteristics and distribution. Peninsular Malaysia is not an exception for this inconsistency, in which it is resulting extreme events such as flood and water scarcity. This study evaluates the seasonal patterns in rainfall indices such as total amount of rainfall, the frequency of wet days, rainfall intensity, extreme frequency, and extreme intensity in Peninsular Malaysia. 40 years (1975-2015) data records have been interpolated using Inverse Distance Weighted method. The results show that the formation of rainfall characteristics are significance during the Northeast monsoon (NEM), as compared to Southwest monsoon (SWM). Also, there is a high rainfall intensity and frequency related to extreme over eastern coasts of Peninsula during the NEM season.
