This article concerns identity work—both the semiotic processes through which it is accomplished and the motivation behind it. Specifically, this article focuses on ethnolinguistic identity: how ...ethnolinguistic grouping is sustained by linguistic ideologies and how rigid categorization is toned down in everyday practice. Using an empirical study of the relations of sameness and distinction established with the Siwan group by non-members through their use—or non-use—of the Siwi language, this article will attempt to show that, based on Siwi's acquired status as an icon of group identity, the language is used as a resource for identity work by non-members to express their position vis-à-vis the Siwan group.
•Ethnolinguistic grouping is sustained by essentialist ideologies.•Portrayed as central to ‘Siwanness’, Siwi becomes an icon of group identity.•Ethnic Siwi is exploited as a way to identify with the ethnolinguistic Siwan group.•Identity inheres in actions—it is fluid and circumstantial.•Analysing situated language–identity relations enriches minority languages studies.
Across the millennia, agricultural activity in the oases of the Sahara was made possible thanks to the shallow water table. However, with the recent agricultural expansion, unsustainable practices ...were introduced with the result that a significant proportion of the areas under cultivation are waterlogged and salinized, of which the case of Siwa oasis is the most severe, where all the solutions implemented to date proved to be unsustainable. The present study suggests an “out-of-the-depression” solution, whereby the excess drainage water could be accommodated in a nearby depression without sacrificing a valuable land. To this end, remote sensing products and geographical information systems were used to assess the capacity of Al ‘Araj Depression, as a candidate sink for the drainage water flowing out of Siwa Depression, and to conduct a suitability analysis, which classifies the lands of the floor of Siwa Depression for the sake of digging a main west-to-east drain that ultimately leads to Al ‘Araj. The results show that Al ‘Araj would be sufficient to accommodate the extra drainage water of Siwa, and the suitability analysis reveals two possible alternatives for a proposed arterial west-to-east drain cutting through Siwa Depression. Moreover, the results are quite applicable to similar problems in the wider context of the African Sahara.
The Siwa region located in the Western Desert of Egypt has 30,000 acres available for reclamation as a part of a national project to increase agricultural production. This study addressed the climate ...change-driven long-term concerns of developing an agricultural project in this region where groundwater from the non-renewable Nubian Sandstone Aquifer System (NSAS) is the only source of water. Different climate models were used under two representative concentration pathways (RCPs); RCP 4.5 and RCP 8.5. Projected seasonal temperatures show that the maximum increase in summer is 1.68 ± 1.64 °C in 2060 and 4.65 ± 1.82 °C in 2100 under RCP 4.5 and RCP 8.5, respectively. The increase in water requirement for crops is estimated around 6–8.1% under RCP 4.5 while around 9.7–18.2% under RCP 8.5. Maximum reductions of strategic crop yields vary from 2.9% to 12.8% in 2060 under RCP 4.5, while from 10.4% to 27.4% in 2100 under RCP 8.5. Project goals are feasible until 2100 under RCP 4.5 but only until 2080 with RCP 8.5. When an optimization analysis was conducted, these goals are possible from 2080 to 2100 by modified land allocation. The proposed methodology is useful to project impact of climate change anywhere such that management and adaptation options can be proposed for sustainable agricultural development.
Abstract: This research was aimed to describe the function of teacher’s motivation speech in SMA Katolik Diponegoro Blitar. The function of speech is divided into three categories, those are the ...function of fact information exchange, function f emotion exchange, and function of convicing of affecting. These three functions appear when the teacher gives the motivation speech in learning process, especially on Bahasa subject. The existence of those functions in the teacher’s motivation speech shows that in the learning process is not only focus on the material delivery, but also giving motivation from the teacher to students with purposed function.
Abstrak: Penelitian ini bertujuan untuk mendeskripsikan tentang fungsi tuturan motivatif guru dalam pembelajaran di SMA Katolik Diponegoro Blitar. Fungsi tuturan ini terbagi menjadi tiga kategori, yakni fungsi tukar-menukar informasi faktual, fungsi tukar-menukar emosi, dan fungsi meyakinkan atau memengaruhi. Ketiga fungsi tersebut muncul pada saat guru tengah memberikan tuturan motivasi dalam pembelajaran, khususnya dalam pembelajaran bahasa Indonesia. Terdapatnya fungsi-fungsi dalam tuturan motivatif guru tersebut menandakan bahwa dalam pembelajaran guru tidak hanya berfokus pada pemberian materi saja, melainkan guru juga memberikan motivasi kepada peserta didik dengan fungsi atau tujuan tersendiri sesuai dengan apa yang dikehendaki guru tersebut.

New media and communication technologies, heritage tourism and new reproductions of local identity are forms of globalization characteristic of the peripheries (Wang, Spotti, Juffermans, Kroon, ...Cornips and Blommaert, 2014:30). This article discusses some effects of globalization in a peripheral area of Egypt, where relative isolation delayed Arabization and favoured the maintenance of the indigenous Berber language, called Siwi. Globalization materialized in important socioeconomic changes that affected the linguistic attitudes and practices of the oasis dwellers. Following Milroy’s (1980) social network approach and Gumperz’ (1982) further elaboration, it is argued that such variation is not related to socioeconomic changes directly, but connected to the structural variation of the community’s social network they provoked. Based on qualitative attitudinal data collected through interviews and participant observation, the study shows that although Egyptian Arabic is widespread and acquires prestige, Siwi not only remains a strong marker of group solidarity but is also becoming a symbol of the Siwan identity.
Detecting and monitoring changes in soil salinity through remote sensing provides an opportunity for field assessment in regions where on-site measurements are limited. This research, conducted in ...Siwa Oasis, Egypt, aimed to assess the effectiveness of remote sensing techniques in detecting and monitoring changes in soil salinity. Using Landsat 5 and Landsat 7 satellite images, the researchers evaluated various soil salinity indices based on 56 on-site ground measurements. The study aimed to improve the correlation between electrical conductivity (EC) and index values and explore the relationship between salinity and changes in land cover. Eleven spectral indices were calculated for nine scenes captured in different months. Different approaches were employed, including stacking the data, categorizing EC measurements into salinity levels, analyzing data temporally, and conducting spatial correlation analysis. The initial approach revealed a weak correlation, due to substantial variation in EC values. However, the salinity index SI demonstrated the highest correlation coefficient of 0.38. In the second scenario, the salinity index 2 S2 index exhibited the highest correlation of 0.96 for moderate salinity samples. The third scenario showed that the salinity index 1S1 achieved the highest correlation value of 0.99 for moderately saline areas. In the fourth scenario, the SI index exhibited the strongest correlation among all four ponds, with correlation coefficients of 0.23, 0.23, 0.18, and 0.61. Notably, the correlations observed in the second and third scenarios demonstrated higher correlation coefficients than those of both the first and fourth scenarios. Additionally, remote sensing methods detected a 48% increase in total vegetated area over 17 years, showing the potential of remote sensing techniques in salinity monitoring for expanding agriculture and improving land management.
A concentration of heavy, thick-shelled, large-sized, and elongated population of the oyster Crassostrea gryphoides (Schlotheim, 1813) was recorded in shallow-marine deposits of the basal Oasis ...Member of the Middle Miocene Marmarica Formation exposed at Siwa Oasis, Egypt. The oyster assemblage is resedimented as a lens-shaped bank up to 80–100 cm thick and about 220 m long. Crassostrea gryphoides specimens are embedded in a yellowish green, soft marl matrix. This is the first documented occurrence of this lens at Siwa Oasis. The lensoid structure is bounded by a lower marl and an upper shale beds of about 2 m and 1.5 m thick, respectively. Assemblage within this lens is characterized by extreme variations of Crassostrea gryphoides, forming an almost monotypic assemblage. The shell packing was dense (shell percentages higher than 75%) at the base and the center of the lens, whereas it exhibits loose packing at the top and right and left sides of the lens (shell percentage less than 15%). Valves are poorly sorted and randomly orientated (both in surface and cross section views). Encrustation and bioerosion have observed on both sides of the left and right valves. The relatively limited varieties of encrusters together with moderate frequency of borings indicate moderate to high sedimentation rate. On the other hand, the low abundance of fragmented and abraded shells indicates good preservation and minimal transport. The studied lens concentration is interpreted as proximal tempestites assemblage.

In this study, the distribution of the chemical constituents (major, minor, and trace elements) is determined in different localities in Egypt’s western desert oases, i.e., Bahariya, Farafra, ...Bahrean, Siwa, El-Gara, and Al-Jaghbub oases. The Nubian Sandstone Aquifer (NSA) is shared between all oases; however, the Limestone Aquifer (LA) is shared only between the western oases, i.e., Bahrean, Siwa, El-Gara, and Al-Jaghbub. The LA is usually located above NSA in Egypt’s western desert. The results indicate notable difference in chemical characteristics between the LA and the NSA waters. Under furrow surface irrigation systems that are commonly used in the Bahariya and Farafra oases, negligible potential for harmful effects on soils and plants is anticipated. However, in case of using drip or sprinkler irrigation systems, the iron and manganese identified in groundwater may precipitate, causing blockages to occur. The LA waters salinity is found to be higher than NSA and above acceptable level for irrigation. Besides, salinity, chloride, and water sodicity make this water unsuitable for irrigation. Durov and piper diagrams reveal that the majority of investigated waters were calcium–magnesium sulfate water type corresponding the Bahariya and Farafra, and sodium, chloride, and sulfate water type corresponding the Siwa, Bahrean, El-Gara, and Al-Jaghbub waters. The saturation indices for minerals indicated that most studied LA waters were undersaturated for halite; however, the NSA waters were saturated with respect to aragonite, calcite, and dolomite.
Siwa Oasis is a tectonically induced depression located in the northern part of the Western Desert. It is intensively characterized by salt mineralization and salt pans. This paper aims to ...investigate the evaluation of salts from the near-surface underground water in Siwa Oasis to assess the quality of salt for several uses. The study results show that the precipitated minerals identified by XRD are halite, sylvite, gypsum, carnallite, magnesium sulfate hydrate, sodium chlorate, and bischofite. More than 90% of NaCl present in the solution precipitate alone in the first stages. Analysis of heavy metals and trace elements indicated that all the salt samples were found at very low concentrations below the allowable limits. The study indicates that the type of Siwa salt is a very good quality salt, which needs a very simple refining process to meet and exceed the international standards of edible (food) salt.
