Quantifying the landscape pattern change can effectively demonstrate the ecological progresses and the consequences of urbanization. Based on remotely sensed land cover data in 1994, 2000, 2006 and a gradient analysis with landscape metrics at landscape- and class- level, we attempted to characterize the individual and entire landscape patterns of Shanghai metropolitan during the rapid urbanization. We highlighted that a roadscape transect approach that combined the buffer zone method and the transect-based approach was introduced to describe the urban-rural patterns of agricultural, residential, green, industrial, and public facilities land along the railway route. Our results of landscape metrics showed significant spatiotemporal patterns and gradient variations along the transect. The urban growth pattern in two time spans conform to the hypothesis for diffusion–coalescence processes, implying that the railway is adaptive as a gradient element to analyze the landscape patterns with urbanization. As the natural landscape was replaced by urban landscape gradually, the urban fringe expanded radically. The results also showed that the desakota region expanded its extent widely. Satellite towns witnessed the continual transformation from the predominantly rural landscape to peri-urban landscape. Furthermore, the gap between urban and rural areas remained large especially in public service. More reasonable urban plans and land use policies should push to make more of an effort to transition from the urban-rural separation to coordinated urban-rural development. This study is a meaningful trial in demonstrating a new form of urban–rural transects to study the landscape change of large cities from a strategic viewpoint. By combining gradient analysis with landscape metrics, we addressed the process of urbanization both spatially and temporally, and provided a more quantitative approach to urban studies.

In much of the Greater Mekong Sub-region, malaria is now confined to patches and small foci of transmission. Malaria transmission is seasonal with the spatiotemporal patterns being associated with variation in environmental and climatic factors. However, the possible effect at different lag periods between meteorological variables and clinical malaria has not been well studied in the region. Thus, in this study we developed distributed lagged modelling accounting for spatiotemporal excessive zero cases in a malaria elimination setting. A multivariate framework was also extended to incorporate multiple data streams and investigate the spatiotemporal patterns from multiple parasite species via their lagged association with climatic variables. A simulation study was conducted to examine robustness of the methodology and a case study is provided of weekly data of clinical malaria cases at sub-district level in Thailand.

This paper reevaluates the ground on which the division into urban and rural gələt dialects, as spoken in Iraq and Khuzestan (south-western Iran), is built on. Its primary aim is to describe which features found in this dialect group can be described as rural and which features tend to be modified or to emerge in urban contexts, and which tend to be retained. The author uses various methodical approaches to describe these phenomena: (i) a comparative analysis of potentially rural features; (ii) a case study of Ahvazi Arabic, a gələt dialect in an emerging urban space; and (iii) a small-scale sociolinguistic survey on overt rural features in Iraqi Arabic as perceived by native speakers themselves. In addition, previously used descriptions of urban gələt features as described for Muslim Baghdad Arabic are reevaluated and a new approach and an alternative analysis based on comparison with new data from other gәlәt dialects are proposed. The comparative analysis yields an overview of what has been previously defined as rural features and additionally discusses further features and their association with rural dialects. This contributes to our general understanding of the linguistic profile of the rural dialects in this geographic context.

The paper deals with the value-based segmentation conducted on Millennials generation in Serbia. It presents the research findings of the five segments of the Serbian Millennials according to their values and life style. The subject of defining the set of segments was processed by conducting a cluster and factor analysis on the representative national sample of Millennials in Serbia. Once the cluster analysis discovered the segments, the next step was to understand the essence of the clusters or segments. The sample is consisted of 1000 respondents, reflecting the population structure of the Serbian generation Y according to gender, age, region and type of settlement (urban / rural). The analysis showed some quite interesting and in some parts contradictory results. The results of this survey are relevant for sociologists, strategists, communications professionals and managers who are interested in this generation of voters, consumers, employees, leaders and entrepreneurs.

Remote Sensing Techniques

One of the most relevant applications of Remote Sensing (RS) techniques is related to the analysis and the characterization of Land Cover (LC) and its change, very useful to efficiently undertake land planning and management policies. Here, a case study is described, conducted in the area of Avellino (Southern Italy) by means of RS in combination with GIS and landscape metrics. A multi-temporal dataset of RS imagery has been used: aerial photos (1954, 1974, 1990), Landsat images (MSS 1975, TM 1985 and 1993, ETM+ 2004), and digital orthophotos (1994 and 2006). To characterize the dynamics of changes during a fifty year period (1954-2004), the approach has integrated temporal trend analysis and landscape metrics, focusing on the urban-rural gradient. Aerial photos and satellite images have been classified to obtain maps of LC changes, for fixed intervals: 1954-1985 and 1985-2004. LC pattern and its change are linked to both natural and social processes, whose driving role has been clearly demonstrated in the case analysed. In fact, after the disastrous Irpinia earthquake (1980), the local specific zoning laws and urban plans have significantly addressed landscape changes.
