Temporal Changes of Land Use Pattern in Batticaloa Municipal Council, Sri Lanka Mathanraj, S.; Ratnayake, R.M.K; Rajendram, K. Batticaloa, one of the fastest-growing cities in Sri Lanka, is the most vital urban agglomeration that should concentrate on the temporal changes in land use. Seven (7) land use categories, namely commercial, residential, agricultural, scrubland, mangroves, water bodies, and barren land in Batticaloa, have changed by the different purposes of utilization. This study aims to identify the landuse changes of the Batticaloa Municipal Council from 1980 to 2018. Primary and secondary data collection methods were used to gather the data for analysis. Maximum likelihood classification method was used to interpret the maps. The comparison was made to the various land use categories in 1980, 1990, 2000, 2010, and 2018. The temporal pattern of land-use change was presented via a comparison of those periods of land use maps. ArcGIS 10.4.1 and MS Excel 2013 were used to interpret the maps and analyze data. The study revealed that there were major land-use changes identified in the study area between 1980 and 2018. Commercial and residential areas increased by 20.17 ha and 1148.57 ha, respectively. Barren land and agricultural land lost 769.54 ha and 301.99 ha, respectively. The certain extent of rest land use categories was converted into some other land use category during these periods. The effects of human activities are immediate and often radical, while the natural effects are relatively long. However, the recommendations are to the future land use planning, protecting mangrove resources through land-use strategies by the government, community participation, and encouraging the approval of urban planners to make decisions about urban development.

PANOPTIC TENSIONS ON RHIZOME: UNDERSTANDING THE IDEOLOGICAL MODEL OF SOCIAL MEDIA Bandara, N. Among many different views and interpretations on the socio-technical underpinnings of social media in new media literature, clarifying two specific standpoints is important for the understanding of ideological model peculiar to social media. As a social phenomenon, the function of the social web, which encompasses social media, has two major concerns. While it is identified through the lens of egalitarianism as ever democratic media, which facilitate decentralized power dynamics and resistance to the dominant hierarchy, it is recognized that social media strengthen the centralized control by facilitating the surveillance of authority along with the technological advancement. Applying the methods of concept analysis, this paper first identifies three basic assumptions -social media, rhizome and panopticism- which are related to the said phenomenon. Then it critically scrutinizes how the concepts of rhizome and panopticism feature in the key facets of social media and their paradoxical functioning in the social media sphere. Dissecting the governing and end-user sides, it finally attempts to reveal the dyad and enigmatic ideological model of social media.
