This article charts the development of the Palestinian Authority from its creation as an interim authority under the Oslo Accords towards becoming a failed (quasi-)state. By 2009 ¿ 15 years after its inception and ten years after the proposed final status negotiations ¿ the PA was split between a criminalized isolated entity in Gaza under the control of Hamas and an internationally recognized ¿caretaker government¿ in the West Bank under the control of Fatah and donor-supported technocrats. The role of violence ¿ i.e. the power of ¿shock and awe¿ ¿ in the creation of this failed (quasi-)state is emphasized: Israel's 2002 military campaign, Operation Defensive Shield, the sanctions and blockade imposed after the election of Hamas in January 2006, and the violence on the Palestinian street which split the PA in two. The article concludes by arguing that the PA failed (quasi-)state is presiding over the demise of the Palestinian dream of a viable state comprising both the West Bank and Gaza.

The Palestinian Authority (PA) offers an interesting case study of statebuilding in a conflict-country context. Created as an interim administration in the West Bank and Gaza in 1994, the PA has been hampered by the statebuilding framework enshrined in the Oslo Accords, its lack of sovereignty, the lack of final status negotiations, and the 'partners for peace' paradigm which is an attempt by donors and international organisations to support who they regard as the 'right' type of elite - that is, those willing to 'make peace' with Israel (as defined by Israel). This article explores the impacts of this paradigm and argues that it has paralysed the formal political process in Palestine and has securitised democracy.

After nearly 20 years of negotiations and peacebuilding, Palestinians are no nearer to self-determination. This article explains this failure through an analysis of the context and peacebuilding framework created as a product of the Oslo Accords and the assumptions of Western donors about how peace would be achieved. It argues that the occupied Palestinian territory (oPt) is subject to an assemblage of colonial practices - some of which are the product of Western peacebuilding. While the practices of the occupying power, Israel, has constituted one part of the colonial equation (extracting and controlling resources and settling its own people), Western peacebuilding has played another through its pursuit of a modern version of the 'mission civilisatrice'. The ideological discursive framework that binds these two parts of the colonial equation together and gives them common purpose is the 'partners for peace' discourse that has been used to justify a multitude of practices, including the arrest and detention of Palestinian politicians, military action, the withdrawal of aid and regime change.

While social constructionist understandings of the self have stressed the importance of the self—other relation, placing emphasis on what happens in dialogues and relations with others rather than psychological processes “in the head,” I suggest here that we can build on this tradition to reintroduce notions of a dialogue with the self, or micro-dialogue, as an important part of an understanding of persons. I use the term “microdialogue,” rather than the more familiar notion of “internal conversation” or “society of mind,” to refer to a silent and invisible series of dialogues we hold for ourselves with the images and voices of others, which can emerge in surprising and unwilled ways. I suggest that this micro-dialogue is important in understanding the dialogical interactions between persons, as not all aspects of the self will enter into dialogue with others, leading to miscommunication, misunderstanding, and misrecognition. It is also possible for people to fail to articulate all the latent voices or vocal tones in their own micro-dialogue, leading to an understanding of how voices and selves can become divided and allowing us to take a different perspective on a dialogical unconscious.

Theories of reflexivity have primarily been concerned with the way agents monitor their own actions using knowledge (Giddens) or deliberate on the social context to make choices through the internal conversation (Archer), yet none have placed emotion at the centre of reflexivity. While emotion is considered in theories of reflexivity it is generally held at bay, being seen as a possible barrier to clear reflexive thought. Here, I challenge this position and, drawing on the work of C.H. Cooley, argue that feeling and emotion are central to reflexive processes, colouring the perception of self, others and social world, thus influencing our responses in social interaction as well as the way we reflexively monitor action and deliberate on the choices we face. Emotional reflexivity is therefore not simply about the way emotions are reflexively monitored or ordered, but about how emotion informs reflexivity itself.

This work presents a technique for shape modelling of cylindrical and spherical tablets subject to compression. This technique is based on the use of partial differential equations (PDEs), the biharmonic equation in particular. The deformation of the compressed elastic-plastic tablet of both shapes was obtained using the existing contact models found in literature. The mathematical properties of the biharmonic equation have been exploited to achieve simple mathematical expressions characterising the shape of the distorted tablet. Thus, the height, radius and contact area of both configurations due to uniaxial compression are represented by analytic expressions relating the coefficients associated with the solution of the biharmonic equation. The results obtained from the PDE-based simulation are compared with the theoretical ones. It is found that the analytic solution of the elliptic PDE can be utilised to represent the physical changes of the deformed object.

This paper considers a study of the thermo-elastic behaviour of a disc brake during heavy braking. The work is concerned with working towards developing design advice that provides uniform heating of the disc, and equally important, even dissipation of heat from the disc blade. The material presented emanates from a combination of modeling, on-vehicle testing but mainly laboratory observations and subsequent investigations. The experimental work makes use of a purpose built high speed brake dynamometer which incorporates the full vehicle suspension for controlled simulation of the brake and vehicle operating conditions. Advanced instrumentation allows dynamic measurement of brake pressure fluctuations, disc surface temperature and discrete vibration measurements. Disc run-out measurements using non-contacting displacement transducers show the disc taking up varying orders of deformation ranging from first to third order during high speed testing. This surface interrogation during braking identifies disc deformation including disc warping, 'ripple' and the effects of 'hot spotting'. The mechanical measurements are complemented by thermal imaging of the brake, these images showing the vane and vent patterns on the surface of the disc. The results also include static surface scanning, or geometry analysis, of the disc which is carried out at appropriate stages during testing. The work includes stress relieving of finished discs and subsequent dynamometer testing. This identifies that in-service stress relieving, due to high heat input during braking, is a strong possibility for the cause of disc 'warping'. It is also seen that an elastic wave is established during a braking event, the wave disappearing on release of the brake.

No / Bone morphogenetic protein (BMP) signaling plays a key role in the control of skin development and postnatal remodeling by regulating keratinocyte proliferation, differentiation, and apoptosis. To study the role of BMPs in wound-induced epidermal repair, we used transgenic mice overexpressing the BMP downstream component Smad1 under the control of a K14 promoter as an in vivo model, as well as ex vivo and in vitro assays. K14-caSmad1 (transgenic mice overexpressing a constitutively active form of Smad1 under K14 promoter) mice exhibited retarded wound healing associated with significant inhibition of proliferation and increased apoptosis in healing wound epithelium. Furthermore, microarray and quantitative real-time reverse-transcriptase-PCR (qRT-PCR) analyses revealed decreased expression of a number of cytoskeletal/cell motility-associated genes including wound-associated keratins (Krt16, Krt17) and Myosin VA (Myo5a), in the epidermis of K14-caSmad1 mice versus wild-type (WT) controls during wound healing. BMP treatment significantly inhibited keratinocyte migration ex vivo, and primary keratinocytes of K14-caSmad1 mice showed retarded migration compared with WT controls. Finally, small interfering RNA (siRNA)-mediated silencing of BMPR-1B in primary mouse keratinocytes accelerated cell migration and was associated with increased expression of Krt16, Krt17, and Myo5a compared with controls. Thus, this study demonstrates that BMPs inhibit keratinocyte proliferation, cytoskeletal organization, and migration in regenerating skin epithelium during wound healing, and raises a possibility for using BMP antagonists for the management of chronic wounds.

No / The growing demand for high-quality middle distillates is increasing worldwide, whereas the demand for low-value oil products, such as heavy oils and residues, is decreasing. Thus, maximizing the production of more liquid distillates of very high quality is of immediate interest to refiners. At the same time, environmental legislation has led to more strict specifications of petroleum derivatives. Hydrotreatment (HDT) of crude oil is one of the most challenging tasks in the petroleum refining industry, which has not been reported widely in the literature. In this work, crude oil was hydrotreated upon a commercial cobalt¿molybdenum on alumina (Co¿Mo/¿-Al2O3) catalyst presulfided at specified conditions. Detailed pilot-plant experiments were conducted in a continuous-flow isothermal trickle-bed reactor (TBR), and the main hydrotreating reactions were hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrodeasphaltenization (HDAs), and hydrodemetallization (HDM), which includes hydrodevanadization (HDV) and hydrodenickelation (HDNi). The reaction temperature (T), the hydrogen pressure (P), and the liquid hourly space velocity (LHSV) were varied with certain ranges, with constant hydrogen to oil (H2/Oil) ratio. The effects of T, P, and LHSV on the conversion of sulfur, nitrogen, vanadium, nickel, and asphaltene were studied. The results showed that high T and P and low LHSV in HDS, HDN, HDV, HDNi, and HDAs of crude oil improve the sulfur (S), nitrogen (N), metals [vanadium (V) and nickel (Ni)], and asphaltene (Asph) conversion. The hydrotreated crude oil has been distilled into the following fractions: light naphtha (LN), heavy naphtha (HN), heavy kerosene (HK), light gas oil (LGO), and reduced crude residue (RCR), to compare the yield of these fractions produced by distillation after the HDT process to those produced by conventional methods (i.e., HDT of each fraction separately after the distillation). The yield of the middle distillate showed greater yield compared to the middle distillate produced by conventional methods. The properties of RCR produced using both methods are also discussed.
