Community Based

This research attempts to identify the existing condition of the community managed forest based on the assumption that it will serve as a proxy for the condition of other forests in the mid hills region of Nepal. The research area has an atypical variation in altitude and diverse pattern of vegetation. This study mainly focuses on estimating carbon content in the forest and identifying the species that has more carbon storage capacity. The research signifies the role of forests in mitigation of ‘Global warming’ and ‘Climate change’ by storing carbon in tree biomass. These types of community based forest management programs are significant for their additional carbon sequestration through the avoidance of deforestation and degradation. The carbon sequestration have a significant contribution to environmental benefits, any shrinkage of forests have an enormous impact on CO2 emission with long term consequences. Thus, the development and expansion of community managed forests provide many benefits to the adjacent community and globally at large.DOI: http://dx.doi.org/10.3126/njst.v12i0.6490 Nepal Journal of Science and Technology 12 (2011) 127-32

Intensively Managed

The nature of society's wood supply is changing. Traditionally, industrial wood has been harvested from natural forests created by nature. In the recent past, however, this situation has been changing. Planted forests have become common in some regions, e.g., much of Europe, over the past 200 years. Recently, since about 1960, intensively managed forest plantations have become increasingly common in a number of regions, including North America, Latin America, Oceania and parts of Asia. This paper explores some of the forces driving plantation forestry and some of the impacts. The experience of the U.S. is given as a type of "case study" of the types of changes that have occurred, and then a broader global discussion is undertaken. The effects of policy, technology and public attitudes on forestry are examined, both as they have influenced the past and as they are likely to impact forestry in the future. Key words: plantations, intensive management, forest policy, technology, public attitudes

Provisioning Services

Provisioning services from forests play a very significant role in sustaining livelihood of rural communities in the Himalayan region. Continuous flow of these services depends on the health of forest ecosystem. The present study identifies basic provisioning services flowing from a community managed forest in the Dhauladhar mountain range (North-west Himalaya) and analyses socio-ecological threats on them. Participatory rural appraisal method and structured interviews were used to collect data. Energy (fuel wood), food (fodder and wild edible plants) and water have been identified as three major provisioning services for the upstream rural communities as well as downstream urban population. A total of 98 species are used from the forests for various purposes. Socio-ecological threats identified for the sustenance of services include spread of invasive species, lack of ecological monitoring and ignorance of stakeholders.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
