Urban research on segregation and integration has been dominated by an obsessive focus on ethno-racial residential patterns, obscuring the multidimensional facets of separation versus encounter that define contemporary urban experience. In this study, we develop an explicitly multidimensional theoretical perspective that relates segregation/integration not only to residential location, but also to daily activity spaces, social networks, transnational media and communications environments, and aspects of identity and sense of place. To disentangle residential location from other facets of segregation/integration, we use GPS and interview data to analyze the socio-spatial experiences of 60 Arab-Palestinian citizens of Israel who live in ethnically homogenous Arab towns—divided equally between “localists” versus “commuters” who spend most of their daytime hours working in Jewish-Israeli spaces. While results highlight many important consequences of commuters’ long hours of daily exposure to Jewish urban mileux, daily activity spaces are only marginally associated with other dimensions of socio-spatial integration. Our analysis reveals evidence of complex relations amongst the multiple dimensions of segregation and integration. Partial integration on a few of these dimensions is insufficient to overcome the structural stratification of Arabs in contemporary Israeli society. 相似文献

ABSTRACT. The tendency to reduce the role of places in the formation of sociospatial identities and to emphasize the impact of sociopolitical structures on place making is growing. We argue that, under certain conditions, places may become salient sources of identity formation. In addition, we suggest viewing different types of places on a continuum from mythical “big places,” to everyday‐life places, to parochial “little places.” We further suggest a distinction between mythical and everyday‐life senses of place. Following Zali Gurevitz, who describes the characteristics of West Bank Jewish settlers' mythical sense of place, we demonstrate how Gaza settlers only partially internalized their conception of place, adopting an everyday‐life conception of thereof. Yet place became a main source of identity for Gaza settlers, who viewed their experience in the settlements as an empowering process that helped them escape their marginality and join the national elite. 相似文献

Zionist geographers in Israel were highly involved in institutionalizing Israel's national identity. In search for interpretative schemes, they were highly committed both to Western paradigms and to Zionist narratives. Until the 1970s, organicist models of regional geography were popular despite contradictions between the use of tragic and comic narratives in Western models and the need to adopt romantic narratives for Zionist purposes. The emergence of historical geography in the 1950s helped to solve these contradictions by adopting a contextual mode of explanation in which the national story has been described in terms of a unique one and as an example for the power of Zionist civilization to transform bewildered nature. During the last two decades, new forms of criticism have emerged that changed the discourse from a particularistic story of nation building to a more general story of colonization and territorial control. 相似文献

[Agrarians] are asking what is the best way to farm in each one of the world's numberless places, as defined by topography, soil type, climate, ecology, history, culture, and local need…. The agrarian standard, inescapably, is local adaptation, which requires bringing local nature, local people, local economy, and local culture into a practical and enduring harmony. 相似文献

Abstract Climatological characteristics of the low‐level tropospheric temperature inversion in the Canadian Arctic are examined using 10–40 year records of upper‐air meteorological data. Inversions at the northern sites are primarily surface‐based in winter, and elevated from mid‐spring through summer. At the southern sites, a bimodal pattern is observed with surface‐based inversions occurring during late summer, as well as during winter. From comparisons of our results with other published climatologies, it appears that this bimodal pattern reflects interactions between short‐ and long‐wave radiation, synoptic activity and snowmelt. Maxima in inversion depth and temperature difference across the inversion layer occur in February and March; minima occur in August and September. The annual progression of inversion characteristics closely follows the annual pattern of clear‐sky percentages, reflecting the controlling influence of cloud and clear‐sky radiative forcings on the inversion layer. 相似文献

Entrepreneurship in the northern periphery in Israel should be viewed as a response to the crisis in rural agriculture during the 1980’s. Most entrepreneurs left their farms for salaried employment for a few years and they took professional courses in order to learn necessary skills before they opened their enterprises. They have developed new small entreprizes using local resources at times informally as means to reduce risks and they specialize mainly in internal tourism and construction related branches. While Jewish entrepreneurs develop mainly tourism activities oriented toward the national market, Arab entrepreneurs develop mainly construction related branches to local and home regional markets. Both represent two styles of peripheral activities. It seems that both styles has only limited potential to overcome their marginality. 相似文献

The purpose of the palaeolimnological research project carried out at Øvre Neådalsvatn was to apply a number of physical and biological proxy-climate analyses to recent sediments and to compare the results of these analyses with instrumental records of climate. Using a radiometric chronology to match the sediment core with the calendar ages of the reconstructed instrumental record, and by time-averaging the instrumental record, the statistical significance of the relationships between each of the sediment-climate proxies and the reconstructed instrumental-climate measurements were evaluated.Acid deposition at Øvre Neådalsvatn has been low and its impact limited. Whilst there has been an overall rise in mean annual temperature of about 1 °C since 1900, the physical and biological sediment records studied appear to be insensitive to climate warming of this magnitude. On the one hand, this may be a result of the loss in temporal resolution caused by time-averaging the instrumental data; on the other hand, the lake may be insensitive to the impact of this climate change. 相似文献

The impact of errors in polar motion and nutation on UT1 determinations from VLBI Intensive observations 总被引：2，自引：2，他引：0
The earth’s phase of rotation, expressed as Universal Time UT1, is the most variable component of the earth’s rotation. Continuous
monitoring of this quantity is realised through daily single-baseline VLBI observations which are interleaved with VLBI network
observations. The accuracy of these single-baseline observations is established mainly through statistically determined standard
deviations of the adjustment process although the results of these measurements are prone to systematic errors. The two major
effects are caused by inaccuracies in the polar motion and nutation angles introduced as a priori values which propagate into
the UT1 results. In this paper, we analyse the transfer of these components into UT1 depending on the two VLBI baselines being
used for short duration UT1 monitoring. We develop transfer functions of the errors in polar motion and nutation into the
UT1 estimates. Maximum values reach 30 [μs per milliarcsecond] which is quite large considering that observations of nutation
offsets w.r.t. the state-of-the-art nutation model show deviations of as much as one milliarcsecond. 相似文献

A palaeoecological study of an oligotrophic alpine lake, Paione Superiore (Italy), provided a record of historical changes in water quality. Historical trends in lake acidification were reconstructed by means of calibration and regression equations from diatoms, chrysophycean scales and pigment ratios. The historical pH was inferred by using two different diatom calibration data sets, one specific to the alpine region. These pH trends, together with the record of sedimentary carbonaceous particles and chironomid remains, indicate a recent acidification of this low alkalinity lake.Concentration of total organic matter, organic carbon, nitrogen, biogenic silica (BSiO2), chlorophyll derivatives (CD), fucoxanthin, diatom cell concentration and number of chironomid head capsules increased during the last 2–3 decades. When expressed as accumulation rates, most of these parameters tended to decrease from the past century to c. 1950, then all except P increased to the present day. A marked increase in sedimentary nitrogen may be related to atmospheric pollution and to the general increases in output of N in Europe. High C/N ratios indicate a prevailing allochthonous source of organic matter.Finally, the increase in measured air temperature from the mid-1800's appeared to be related to lake water pH before industrialization: cold periods generally led to lower pH and vice-versa. The more recent phenomenon of anthropogenic acidification has apparently decoupled this climatic-water chemistry relationship. 相似文献
