Practicing peace: Psychological roots of transforming conflicts

The practice of sustainable peace is a process that must be initiated, nourished and revised. The
“social energies” of conflict transformation – truth, mercy, justice, peace – offer a useful model to describe the transformative power of this practice. These social energies can be conceptualized as a combination of norms or values, on the one hand, and actions directed toward social reconstruction, on the other. As such, the social energies of conflict transformation are both the guideposts and the engine in the journey of practicing sustainable peace. This article begins by
linking psychological constructs of narrative/voice, empathy/altruism, individual/collective guilt, and security/fear with the social energies, highlighting the interdependence of processes and shifting the focus away from pathology toward an emphasis on harmony. An empirical application of how the four social energies contribute to the mobilization, maintenance and adaptations in on-going peace processes in post-war Guatemala is then presented. By analyzing the interaction among diverse actors and goals in the decade and a half since the signing of the 1996 Peace Accords, current theory is extended in two ways: a) differentiation between elite and grassroots initiatives, and b) specification and evaluation the impact of various efforts on episodic and structural violence. We conclude that although national and local processes have
had limited success, more integrated practices of truth, mercy, justice and peace are necessary if Guatemala is to make sustainable peace a reality. The findings from this case study have policy and practical implications for other countries facing protracted, violent conflict.

Metaphor and Matter(s) Arising: Gongorine Metaphor and the Cultivation of the Imagination

This article focuses on the concept of metaphor as metaphorai, as varied means of transfer and transport, specifically on Góngora's innovative development of the metaphor as a vehicle for experiential transformation and epistemological exploration; ultimately emphasizing a hitherto neglected valorization of affect in the liberation of the imagination. Although Góngora's use of metaphor became a major source of controversy in the debate unleashed by the Polifemo and Soledades during his lifetime, the Generation of 1927 looked to Gongorine metaphor as model and inspiration for their cultivation of imaginary worlds through poetry. By examining the models and concepts that nourished Góngora's innovative engagement with metaphor, shaped readers' responses to the poet's imaginary worlds of metaphor, triggered the recovery and reframing of Gongorine metaphor as springboard for the poetic imagination in the twentieth century, and sheds light on the power of Góngora's metaphor to transform and transmute the world through the exercise of the imagination.

A biogeography-based optimization algorithm with mutation strategies for model parameter estimation of solar and fuel cells

Mathematical models are useful tools for simulation, evaluation, optimal operation and control of solar cells and proton exchange membrane fuel cells (PEMFCs). To identify the model parameters of these two type of cells efficiently, a biogeography-based optimization algorithm with mutation strategies (BBO-M) is proposed. The BBO-M uses the structure of biogeography-based optimization algorithm (BBO), and both the mutation motivated from the differential evolution (DE) algorithm and the chaos theory are incorporated into the BBO structure for improving the global searching capability of the algorithm. Numerical experiments have been conducted on ten benchmark functions with 50 dimensions, and the results show that BBO-M can produce solutions of high quality and has fast convergence rate. Then, the proposed BBO-M is applied to the model parameter estimation of the two type of cells. The experimental results clearly demonstrate the power of the proposed BBO-M in estimating model parameters of both solar and fuel cells.

Poetic Inquiry, Consumer Vulnerability: Realities of Quadriplegia

Alternative forms of research interpretation have been utilised within the social sciences. Poetic inquiry, an area of growing interest influences readership affectively as well as intelligently. Incorporating interview data as a poetic submission, this paper intends to reflexively capture, emotional intensity, hopelessness, liminality, voicelessness and self-transformative realities attendant to those experiencing vulnerability. The unintelligible language that can appropriate the poetic form, supports the elucidation of hidden narratives of more vulnerable inscapes. Consumer vulnerability lends itself to the power of poetry for legitimacy of the moment, where sensory imagery and nonce words attend hiatuses common in scientific discourse. The poetic inquiry, Vulnerability in Parts, is elicited from wider research with homebound consumers conducted over a two-year period, which draws on one homebound consumer’s experience of quadriplegia.

Identifying the relative importance of stock characteristics

There is no consensus in the literature as to which stock characteristic best explains returns. In this study, we employ a novel econometric approach better suited than the traditional characteristic sorting method to answer this question for the UK market. We evaluate the relative explanatory power of market, size, momentum, volatility, liquidity and book-to-market factors in a semiparametric characteristic-based factor model which does not require constructing characteristic portfolios. We find that momentum is the most important factor and liquidity is the least important based on their relative contribution to the fit of the model and the proportion of sample months for which factor returns are significant. Overall, this study provides strong evidence to support that the momentum characteristic can best explain stock returns in the UK market. The econometric approach employed in this study is a novel way to assess relevant investment risk in international financial markets outside U.S. Moreover, multinational institutions and investors can use this approach to identify regional factors in order to diversify their portfolios.

Implementation of a cogeneration plant for a food processing facility. A case study

The present work presents an investigation regarding the feasibility analysis of a cogeneration plant for a food processing facility with the aim to decrease the cost of energy supply. The monthly electricity and heat consumption profiles are analyzed, in order to understand the consumption profiles, as well as the costs of the current furniture of electricity and gas. Then, a detailed thermodynamic model of the cogeneration cycle is implemented and the investment costs are linked to the thermodynamic variables by means of cost functions. The optimal electricity power of the co-generator is determined with reference to various investment indexes. The analysis highlights that the optimal dimension varies according to the chosen indicator, therefore it is not possible to establish it univocally, but it depends on the financial/economic strategy of the company through the considered investment index.

The reception of British literature under dictatorships in Hungary and Portugal

Esta tese tem como objectivo comparar aspectos da recepção da literatura britânica durante o Estado Novo em Portugal, e na Hungria durante a era comunista. Na primeira parte da dissertação fica contextualizada e analisada a alteração da posição da literatura britânica nos dois países, enquanto na segunda parte se comparam facetas da recepção da mesma, contrastando as traduções literárias publicadas em Portugal e na Hungria entre 1949 e 1974, altura em que ambos os países foram dirigidos simultaneamente por regimes autocratas. Este estudo faz-se, em parte, através da comparação de manuais escolares e seletas, a fim de examinar os diferentes métodos usados pelos dois regimes ditatoriais politicamente opostos na tentativa de moldarem os seus leitores. É dada especial atenção à literatura proibida e aos motivos para as atitudes restritivas diferenciadas em relação a certos escritores na era de Salazar e na Hungria durante o período de Bloco de Leste. A tese conclui que a abordagem divergente em relação às obras literárias britânicas, bem como à literatura em geral, é principalmente enraizada na ideologia de governação diametralmente oposta dos dois regimes ditatoriais. A crença idealista no poder educativo da literatura em estabelecer o socialismo na Hungria está em nítido contraste com a política de cultura obscurantista do Estado Novo. Mesmo quando o apoio à literatura britânica não era uma das principais prioridades da esfera cultural húngara, parece evidente que a literatura canónica britânica teve uma recepção mais favorável na Hungria comunista do que no Estado Novo.

Derivation of soil screening values for metals in Portuguese natural soil

The increasing human activity has been responsible by profound changes and a constinuos degradation of the soil compartment in all the European territory. Some European policies are appearing focusing soil’s protection and the management of contaminated sites, in order to recover land for other uses. To regulate the risk assessment and the management of contaminated soils, many European member states adopted soil guideline values, as for example soil screnning values (SSV).These values are particularly useful for the the first tier of the Ecological Risk Assessment (ERA) processes of contaminated sites,especially for a first screening of sites requiring a more site-specific evaluation. Hence, the approriate definition of regional SSVs will have relevant economic impacts in the management of contaminated sites. Portugal is one of European Member States that still lack these soil guideline values. In this context, this study gaves a remarkable contribution in the generation of ecotoxicological data for soil microbiological parameters, terrestrial plants and invertebrates for the derivation of SSVs for uranium (U), cadmium (Cd) and copper (Cu), using a Portuguese natural soil, representative of a dominant type of soil in the Portuguese territory. SSVs were derived based on two methods proposed by the the Technical Guidance Document for Risk Assessment of the European Commission; namely the assessment factor method (AF) and the species sensitivity distribution (SSD) method (with some adaptations). The outputs of both methods were compared and discussed. Further, this study laid the foundation for a deeper reflection about the cut-off (hazard concentration for a given percentage of species - HCps) to be estimated from the SSDs, and to be selected for the derivation of SSVs, with the adequate level of protection. It was proven that this selection may vary for different contaminants, however a clear justification should be given, in each case. The SSvs proposed in this study were for: U (151.4 mg U kg-1dw), Cd (5.6 mg Cd kg-1dw), and Cu (58.5 mg Cu kg-1dw) These values should now be tested for their descriminating power of soils with different levels of contamination. However, this studies clarifies the approach that should be followed for the derivation of SSVs for other metals and organic contaminants, and for other dominant types of Portuguese natural soils.

Conversations with remarkable teachers an exploration of teaching as healing

Through analysis and interpretation of transcribed taped conversations with two remarkable University teachers, Joel Shack and Harry Whittier, an articulation of perception and metaphor that exists in effective teaching, emerges as life giving or transformational. Creative insight and interpretation connect teaching to life. This work demonstrates how insightful conversations about teaching relate to poetic essence (Joel), energy (Harry), and healing (Ray), all aspects of a similar perceptual, creative and transformative process. Teachers shape education and excellent teaching inspires insofar as it is inspirited. Effective teaching is highly conscious and intentional. So much depends on how aware the teacher is, how the teacher sees what s/he is doing and how this doing/teaching is received. The effective teacher, attentive to how this energy works, can provoke positive change in consciousness both in the student, in education and in society. My study draws attention to the healing power of the teacher as he/she teaches and to the process of dialogue as teachers talk about what they do and don't do. For inherent in conversation and dialogue is the desire to affirm whole perceptions of existence. Dialogue and conversation is necessary to creating the kind of consciousness that will aid the reflective and conscientious teacher. The effective teacher attempts to effect change, to make things better. I call this transforming process, healing. And what creates this healing is the life, the attitude and approach of the teacher. The teacher's energy and consciousness, the teacher's perception of meaning, is the active but implicit ingredient in this transformative and healing process. These conversations are creative, theoretical, illuminating and even practical. It is my hope that the contents of these conversations will inspire potential teachers who can consider the vocation of teaching as a healing process that promises to generate positive growth in mind, body and spirit.

Automatic parallelization of matricial algorithms

The introduction of parallel processing architectures allowed the real time impelemtation of more sophisticated control algorithms with tighter specifications in terms of sampling time. However, to take advantage of the processing power of these architectures the control engeneer, due to the lack of appropriate tools, must spend a considerable amount of time in the parallelizaton of the control algorithm.

Introduction: the impact of the 'War on Terror' on executive–legislative relations: a global perspective

In democratic polities, constitutional equilibria or balances of power between the executive and the legislature shift over time. Normative and empirical political theorists have long recognised that war, civil unrest, economic and political crises, terrorist attacks, and other events strengthen the power of the executive, disrupt and threaten constitutional politics, and damage democratic institutions: crises require swift action and executives are thought to be more capable than parliaments and legislatures of taking such actions. The terrorist attacks on New York and Washington on 11 September 2001 and the ensuing so-called 'war on terror' declared by President Bush clearly constituted a crisis, not only in the United States but also in other political systems, in part because of the US's hegemonic position in defining and shaping many other states' foreign and domestic policies. Dicey, Schmitt, and Rossiter suggest that critical events and political crises inevitably trigger the concentration of (emergency) powers in the hands of the executive. Aristotle and Machiavelli questioned the inevitability of this process. This article and the articles that follow in this Special Issue utilise empirical evidence, through the use of case studies of the United States, the United Kingdom, Russia, Australia, Israel, Italy and Indonesia, to address this debate. Specifically, the issue explores to what extent the external shock or crisis of 9/11 (and other terrorist attacks) and the ensuing 'war on terror' significantly changed the balance of executive-legislative relations from t (before the crisis) to t+1 (after the crisis) in these political systems, all of which were the targets of actual or foiled terrorist attacks. The most significant findings are that the shock of 9/11 and the 'war on terror' elicited varied responses by national executives and legislatures/parliaments and thus the balance of executive-legislative relations in different political systems; that, therefore, executive-legislative relations are positive rather than zero-sum; and that domestic political contexts conditioned these institutional responses.

From dispersed to monopolized violence: expansion and consolidation of the Primeiro Comando da Capital's hegemony in São Paulo's prisons

The present work aims to understand the process of expansion and consolidation of the organized criminal group the Primeiro Comando da Capital (PCC) in São Paulo’s prison system over the past 20 years, and the social configuration that has formed as a result of the PCCs monopolization of opportunities of power. To this end, the work of Norbert Elias is utilized to analyze empirical data collected from various sources. The article consists of two lines of analysis. First, the PCC phenomenon is approached from a macro-sociological point of view, focusing on the social, political and administrative problems that are directly or indirectly linked to the PCCs social development. Second, a figurational analysis is used to explore the social dynamics produced from this process. In comparison to the “pre-PCC” situation, it is shown that the new social configuration produced from the hegemony of the PCC consists of a complexity of interdependencies, including greater functional division and social integration. Given this intensification of mutual dependencies, the social controls on individual behavior have been expanded and centralized. Here, the structure and organization of the PCC, its political dynamics, and individual self-control are central issues. The article concludes by calling into question the view that the most significant effect of the PCCs consolidation has been social pacification of São Paulo’s prison system. Fragilities in the power of the PCC are explored, principally the precarious nature of the relationship between the PCC and state authorities, and the extent to which the PCC’s authority is imposed.
