This study examines how accurate young adults in the Iraqi Kurdistan Region, as an emerging democracy in the Middle East, express their core values through social media （Facebook in this context）. It also explores whether privacy affects with value disclosure. Findings show that value disclosure and definition of privacy varied greatly among respondents and from one value to another. Based on in-depth interview with 12 young adults, the study finds that religious, social, and cultural values have been easily and freely expressed on Facebook accounts by the majority of young adults, whereas other values such as honesty, freedom of speech, and political beliefs are being held by others mainly for privacy issues and political reasons. Democracy was a core value for some young adults seeking to make sense of the western principles of democracy and that reflect on their Facebook account. Results suggest that male respondents practice more freedom and less caution about their privacy than the female respondents on Facebook.

The Pushtashan suprasubduction zone assemblage of volcanic rocks, gabbros, norites and peridotites occurs in the Zagros suture zone, Kurdistan region, northeastern Iraq. Volcanic rocks are dominant in the assemblage and consist mainly of basalt and basaltic andesite flows with interlayered red shale and limestone horizons. Earlier lavas tend to be MORB-like, whereas later lavas display island arc tholeiite to boninitic geochemical characteristics. Tholeiitic gabbros intrude the norites and display fractionation trends typical of crystallisation under low-pressure conditions, whereas the norites display calc-alkaline traits, suggesting their source included mantle metasomatised by fluids released from subducted oceanic crust. Enrichment of Rb, Ba, Sr, Th and the presence of negative Nb anomalies indicate generation in a suprasubduction zone setting. Trondhjemite and granodiorite intrusions are present in the volcanic rocks, gabbros and norites. SHRIMP U-Pb dating of magmatic zircons from a granodiorite yields a mean^(206)Pb/^(238)U age of 96.0 ±2.0 Ma(Cenomanian). The initial ε_(Hf) value for the zircons show a narrow range from +12.8 to+15.6, with a weighted mean of + 13.90±0.96. This initial value is within error of model depleted mantle at 96 Ma or slightly below that, in the field of arc rocks with minimal contamination by older continental crust. The compositional bimodality of the Pushtashan suprasubduction sequence suggests seafloor spreading during the initiation of subduction, with a lava stratigraphy from earlyerupted MORB transitioning into calc-alkaline lavas and finally by 96 Ma intrusion of granodioritic and trondhjemitic bodies with juvenile crustal isotopic signatures. The results confirm another Cretaceous arc remnant preserved as an allochthon within the Iraqi segment of the Cenozoic Zagros suture zone. Implications for the closure of Neo-Tethys are discussed.

Laws and policies impose many information handling requirements on business practices. Compliance with such regu-lations requires identification of conflicting interpretations of regulatory conditions. Current software engineering methods extract software requirements by converting legal text into semiformal constraints and rules. In this paper we complement these methods with a state-based model that includes all possibilities of information flow. We show that such a model provides a foundation for the interpretation process.
