The development of mobile robot for air pollution data capture (POPOBOT)

In the Modern era, the environmental issues have given significant impact to the human live. The air pollution indoor and outdoor environment sometimes dangerous to the human health and it needs to be justified. To fulfill this purpose, telemeasurement process and technique should be used. Therefore, in this research, the mobile robot with equipped by several air quality parameters sensors is developed. The robot is controlled using remote control and using wireless connection system. The air quality in target area will be monitored by using sensors which will capture data and send it to the Central Control (laptop) for analyzing. And then to be able monitor certain area investigation, the mobile robot is guided by using wireless camera. Result from this project can make user to monitor and navigate the target area by using mobile robot and this can make user know the situation on that area. PIC16F887A has been chosen in this project as the main device which is controlling all activities of the mobile robot. Data capture and robot movement has been done in wireless to make user easy to do the monitoring activities. From result, knowing that the error percentage of the data capture is small compare to the digital meter. So from that knowing this project is effective because it make user easy to do air pollution monitoring process also can prevent the gas poisoning cases from happen

Malaysia and Singapore in the world economy : state, capitalism, and authoritarianism

This dissertation is a comparative historical analysis between Malaysia and Singapore on the relationship between capitalist development and authoritarianism. Both Malaysia and Singapore have recorded remarkable economic growths and rapid industrial development, but both these countries have also shown to be moving toward state authoritarian rule. The rise of authoritarianism in these countries is analyzed through four interactive state development-related variables that shape the nature of politics in these countries. First is the development of institutions that have enabled the state to assume and strengthen its power over all other social forces. This in turn has empowered the state to forge alliances with both foreign and local capitalists in order to survive in the world economy. In this regard, even though so-called democratic institutions such as representative government and electoral processes are seen to exist, their effectiveness as genuine democratic institutions is limited. Second, social and political tensions entrenched in ethnonational-class inequalities have given rise to serious difficulties in the formation of cross-ethnonational popular alliances. These difficulties arise not from the multi-ethnonational character of society but rather from the domination of economic power by one group used to politically subsume other groups. The state also frequently justifies authoritarian rule as a way to suppress ethnonational tensions and enforce coexistence between the various groups. Third, the dependent nature of capitalist development itself aggravates existing wealth concentration, thereby reinforcing statecapital alliances and widening existing disparities. The more dependent the state is, the more repressive is its administration to accommodate capital investments. Fourth, peripheral state development has thrust the state into the leading role of economic planning as well as policy formulation. Thus by exploiting ideologies constructed around economic nationalism, the state often justifies its authoritarian rule as a politically legitimate means of attaining an economically prosperous end. Both Malaysia and Singapore are chosen for this comparative study due to their phenomenal economic growth, their development toward state authoritarian rule, and their unique social-political histories, that in many ways set these countries apart from many capitalist peripheral states

Situation complexity: delineating situational factors affecting individual communicative action in problem solving

The rapid development of new social media technologies has provided today’s individual with a variety of communicative tools that enable the dissemination of information to large groups of people in a very short amount of time. Individuals who converge into collectives are viewed as influential forces in the creation of problem perception, and have the potential to influence society and pressure the organisations within it. For this reason, understanding audiences and managing information is of interest to communications practitioners and scholars alike. Of late, the study of the individual problem solving process has become an important focus; more specifically, the communicative behaviour of individuals and the factors that influence these communicative behaviours. Previous studies have examined three key antecedent factors that determine an individual’s participation in communicative action: problem recognition, involvement recognition, and constraint recognition. This study proposes that the problem solving process is also influenced by contextual factors that may limit or encourage communicative behaviour. The purpose of this study was to delineate the “situation” in the individual problem solving process and construct a quantitative measure of perceived situation complexity. A synthesis of extant literature produced preliminary dimensions and items that were tested through a survey distributed among 152 university students. Exploratory factor analysis yielded six main dimensions: solution complexity, referent criterion, negative feelings toward the problem, environmental salience, problem familiarity, and uncertainty of a solution. These results provide initial guidance into exploring the concept of context in individual problem solving and the consequences on communicative action

Correlation between Soil Organic Matter, Total Organic Matter and Water Content with Climate and Depths of Soil at Different Land use in Kelantan, Malaysia

A total of four sites distributed in different soils of Kelantan State, Malaysia was identified for the study. Soils were collected by depth interval of 0-10cm, 10-20cm and 20-30cm. The correlation of soil organic matter (SOM) content, total organic carbon (TOC) content, water content and soils texture for industrial area at Pengkalan Chepa, township of Kota Bharu district, agricultural area at Banggu and forested area in UMK, Jeli were investigated. These data sets were also correlated to temporal event in Kelantan State. Correlation analysis indicated that,generally, SOM and TOC concentration and soil classes had a positive correlation with temporal patterns and no significance effects with depth of the soils. The relationships between SOM content, TOC content and clay + silt content, were also studied. The results showed that, SOM concentration was lower (P < 0.05) at Pengkalan Chepa area (1.96%) compared to Kota Bharu (2.06%), Banggu (2.77%) and Jeli (7.39%). At the same time, the TOC level also showed that Banggu area recorded the lowest concentration (0.42%) followed by Kota Bharu (0.71%), Pengkalan Chepa (0.76%) and Jeli (3.73%). The temporal factor (p < 0.05) showed that TOC content higher during dry season (1.76%) and lower during pre monsoon (0.48%) and lowest in monsoon season (0.25%). Similar results were obtained for SOM content, higher during dry season (4.00%) followed by pre monsoon (2.12%) and lowest in monsoon season (1.67%). The lowest TOC and SOM content in soil during monsoon season was believed to be due heavy rain which detaches all the organic matter from soil particles into river.J. Appl. Sci. Environ. Manage.

The impact of surplus free cash flow and stock market segmentations on earnings management in Jordan: agency - and institutional - theory perspectives / Ahmad A. Toumeh, Sofri Yahya and Azlan Amran.

The current research aims at providing evidence concerning the influence of surplus free cash flow (SFCF) and stock market segmentations (SMS) on income-increasing earnings management practices in Jordan. The results, based on a sample of all non-financial companies that were listed on the Amman Stock Exchange (ASE) from 2013 to 2017, confirm the research hypotheses. The Huber-White’s sandwich standard errors for randomeffects regression was used as the primary statistical tool for this study. The findings revealed a significant and positive association between SFCF and income-boosting discretionary accruals (DAC). As well, the results found that SMS was significantly and positively associated with the positive DAC. This research adds value to scholarship by investigating the impact of SMS variable on earnings management. To the best available knowledge, this relationship has not been examined either in Jordan or elsewhere in the world. Further, this is the first empirical attempt to investigate the effect of SFCF on earnings management in Jordan, which provides meaningful information for companies seeking to understand and reduce agency problems within the Jordanian context

The Role of Habitat Heterogeneity in Structuring Mangrove Bird Assemblages

Mangrove habitats are under severe land use pressure throughout the world and Australia is no exception. Here we describe the heterogeneity of mangrove habitat and its relationship with mangrove bird diversity. We examined the role of mangrove habitat complexity in determining the richness of avian mangrove dependent species (MDS) and interior species, overall bird species richness and density. High species richness (overall and MDS) and density in the mangroves was associated with plant species richness, the density of the understory and food resource distribution. Furthermore, habitat heterogeneity rather than patch area per se was a more important predictor of species richness in the mangroves. These findings stress the importance of habitat diversity and quality to the diversity and density of birds in mangroves. Thus, habitat heterogeneity within mangroves is a crucial patch characteristic, independent of mangrove patch size, for maintaining diverse avian species assemblages
