Introduction: Conflict Resolution and Social Justice

A daunting obstacle to clarity in formulating ideas about conflict resolution and social justice is the fact that each of these terms has multiple meanings. There is widespread recognition that social justice is a multivalent phrase. Commentators since Aristotle have written of distributive, restitutive, retributive, procedural, and relational justice, and each of these types has been further subdivided to reflect differences in social philosophy and in common usage. Less well recognized is the ambiguity of conflict resolution, a term that refers to a mélange of theories and practices that, although interrelated, do not constitute a cleanly demarcated and coherently defined whole. To name a few large subdivisions in this evolving field, we are accustomed to speak of alternative dispute resolution, principled negotiation, relational transformation, public dispute resolution, analytical conflict resolution, and individual or communal reconciliation processes

Methodology for urban rail and construction technology research and development planning

A series of transit system visits, organized by the American Public Transit Association (APTA), was conducted in which the system operators identified the most pressing development needs. These varied by property and were reformulated into a series of potential projects. To assist in the evaluation, a data base useful for estimating the present capital and operating costs of various transit system elements was generated from published data. An evaluation model was developed which considered the rate of deployment of the research and development project, potential benefits, development time and cost. An outline of an evaluation methodology that considered benefits other than capital and operating cost savings was also presented. During the course of the study, five candidate projects were selected for detailed investigation; (1) air comfort systems; (2) solid state auxiliary power conditioners; (3) door systems; (4) escalators; and (5) fare collection systems. Application of the evaluation model to these five examples showed the usefulness of modeling deployment rates and indicated a need to increase the scope of the model to quantitatively consider reliability impacts

Role for TGF-beta superfamily signaling in telencephalic GABAergic neuron development.

Signaling mechanisms mediated by the Transforming Growth Factor-beta (TGF-beta) superfamily regulate a variety of developmental processes. Here we show that components of both bone morphogenetic protein/growth differentiation factor and TGF-beta/activin/Nodal branches of TGF-beta superfamily signaling are expressed in the developing subpallium. Furthermore, Smad proteins, transcriptional effectors of TGF-beta signaling, are co-expressed and physically interact in the basal ganglia with Dlx homeodomain transcription factors, which are critical regulators of the differentiation, migration and survival of telencephalic GABAergic neurons. We also show that Dlx and Smad proteins localize to promoters/enhancers of a number of common telencephalic genes in vivo and that Smad proteins co-activate transcription with Dlx family members, except with certain mutated human DLX proteins identified in autistic individuals. In agreement with these observations, expression of dominant-negative Smads in the developing basal ganglia phenocopies the cell migration defects observed in Dlx1/2-deficient mice. Together, these results suggest that TGF-beta superfamily signaling plays a role in telencephalic GABAergic neuron development through functional interactions with Dlx transcription factors.

Conflict Resolution and Distributive Justice: Reflections on the Burton-Laue Debate

Excerpt From its inception, the field of conflict resolution has appealed strongly to practitioners, researchers, and theorists interested in social betterment. Most conflict resolvers would probably agree that their efforts are motivated, at least in part, by the conception of a Good (or at least a Better) Society considerably less violent and contentious, more peaceful and cooperative, than the existing social order. Many would also affirm that in order to reach this goal, the sources of violence and contention, which include cultural norms sanctioning or glorifying violence, invidious and discriminatory isms (racism, sexism, etc.), gross socioeconomic and political inequities, and over-reliance on formal, adversarial decision-making procedures need to be eliminated or, at least, mitigated. And many would assert, in addition, that the methods of making these changes should be consistent, so far as possible, with the aims sought to be achieved: that is, they should rely on nonviolent conflict resolution.

Unfolding cross-linkers as rheology regulators in F-actin networks

We report on the nonlinear mechanical properties of a statistically homogeneous, isotropic semiflexible network cross-linked by polymers containing numerous small unfolding domains, such as the ubiquitous F-actin cross-linker Filamin. We show that the inclusion of such proteins has a dramatic effect on the large strain behavior of the network. Beyond a strain threshold, which depends on network density, the unfolding of protein domains leads to bulk shear softening. Past this critical strain, the network spontaneously organizes itself so that an appreciable fraction of the Filamin cross-linkers are at the threshold of domain unfolding. We discuss via a simple mean-field model the cause of this network organization and suggest that it may be the source of power-law relaxation observed in in vitro and in intracellular microrheology experiments. We present data which fully justifies our model for a simplified network architecture.Comment: 11 pages, 4 figures. to appear in Physical Review

Research Investments and Market Structure in the Food Processing, Agricultural Input, and Biofuel Industries Worldwide

Meeting growing global demand for food, fiber, and biofuel requires robust investment in agricultural research and development (R&D) from both public and private sectors. This study examines global R&D spending by private industry in seven agricultural input sectors, food manufacturing, and biofuel and describes the changing structure of these industries. In 2007 (the latest year for which comprehensive estimates are available), the private sector spent 19.7 billion on food and agricultural research (56 percent in food manufacturing and 44 percent in agricultural input sectors) and accounted for about half of total public and private spending on food and agricultural R&D in high-income countries. In R&D related to biofuel, annual private-sector investments are estimated to have reached 1.47 billion worldwide by 2009. Incentives to invest in R&D are influenced by market structure and other factors. Agricultural input industries have undergone significant structural change over the past two decades, with industry concentration on the rise. A relatively small number of large, multinational firms with global R&D and marketing networks account for most R&D in each input industry. Rising market concentration has not generally been associated with increased R&D investment as a percentage of industry sales.agricultural biotechnology, agricultural chemicals, agricultural inputs, animal breeding, animal health, animal nutrition, aquaculture, biofuel, concentration ratio, crop breeding, crop protection, farm machinery, fertilizers, Herfindahl index, globalization, market share, market structure, research intensity, seed improvement, Productivity Analysis,

Child health in Syria: recognising the lasting effects of warfare on health

The war in Syria, now in its fourth year, is one of the bloodiest in recent times. The legacy of war includes damage to the health of children that can last for decades and affect future generations. In this article we discuss the effects of the war on Syria's children, highlighting the less documented longer-term effects. In addition to their present suffering, these children, and their own children, are likely to face further challenges as a result of the current conflict. This is essential to understand both for effective interventions and for ethical reasons
