The practices and decision-making of contemporary agricultural producers are governed by a multitude of different, and sometimes competing, social, economic, regulatory, environmental and ethical imperatives. Understanding how they negotiate and adapt to the demands of this complex and dynamic environment is crucial in maintaining an economically and environmentally viable and resilient agricultural sector. This paper takes a socio-cultural approach to explore the development of social resilience within agriculture through an original and empirically grounded discussion of people-place connections amongst UK farmers. It positions enchantment as central in shaping farmers' embodied and experiential connections with their farms through establishing hopeful, disruptive and demanding ethical practices. Farms emerge as complex moral economies in which an expanded conceptualisation of the social entangles human and non-human actants in dynamic and contextual webs of power and responsibility. While acknowledging that all farms are embedded within broader, nested levels, this paper argues that it is at the micro-scale that the personal, contingent and embodied relations that connect farmers to their farms are experienced and which, in turn, govern their capacity to develop social resilience.

P>The aim of this research was to study spray drying as potential action to protect chlorophyllide from environmental conditions for shelf-life extension and characterisation of the powders. Six formulations were prepared with 7.5 and 10 g of carrier agents [gum Arabic (GA), maltodextrin (MA) and soybean protein isolate (SPI)]/100 mL of chlorophyllide solutions. The powders were evaluated for morphological characteristics (SEM), particle size, water activity, moisture, density, hygroscopicity, cold water solubility, sorption isotherms, colour and stability, during 90 days. All the powders were highly soluble, with solubility values around 97%. A significant lower hygroscopicity was observed for GA powders, whilst the lower X(m) values obtained by GAB equation fitting of the sorption isotherms was observed for the 7.5 g MA/100 mL samples. All formulations, but the 1 (7.5 g SPI/100 mL of chlorophyllide), provided excellent stability to the chlorophyllide during 90 days of storage even at room temperature.

This thesis is done to solve two issues for Sayid Paper Mill Ltd Pakistan. Section one deals with a practical problem arise in SPM that is cutting a given set of raw paper rolls of known length and width, and a set of product paper rolls of known length (equal to the length of raw paper rolls) and width, practical cutting constraints on a single cutting machine, according to demand orders for all customers. To solve this problem requires to determine an optimal cutting schedule to maximize the overall cutting process profitability while satisfying all demands and cutting constraints. The aim of this part of thesis is to develop a mathematical model which solves this problem.Second section deals with a problem of delivering final product from warehouse to different destinations by finding shortest paths. It is an operational routing problem to decide the daily routes for sending trucks to different destination to deliver their final product. This industrial problem is difficult and includes aspect such as delivery to a single destination and multiple destinations with limited resources. The aim of this part of thesis is to develop a process which helps finding shortest path.

The main idea of this research to solve the problem of inventory management for the paper industry SPM PVT limited. The aim of this research was to find a methodology by which the inventory of raw material could be kept at minimum level by means of buffer stock level.The main objective then lies in finding the minimum level of buffer stock according to daily consumption of raw material, finding the Economic Order Quantity (EOQ) reorders point and how much order will be placed in a year to control the shortage of raw material.In this project, we discuss continuous review model (Deterministic EOQ models) that includes the probabilistic demand directly in the formulation. According to the formula, we see the reorder point and the order up to model. The problem was tackled mathematically as well as simulation modeling was used where mathematically tractable solution was not possible.The simulation modeling was done by Awesim software for developing the simulation network. This simulation network has the ability to predict the buffer stock level based on variable consumption of raw material and lead-time. The data collection for this simulation network is taken from the industrial engineering personnel and the departmental studies of the concerned factory. At the end, we find the optimum level of order quantity, reorder point and order days.

Purpose of the research/paper: The views and values of managers are typically noted as being wedded to unitarist or pluralist ideals. This paper disaggregates these views and values by looking at the impact of various managerial styles on employment relations in different sized organisations.
Methodology: Conceptual with applied support from the secondary literature.
Findings: The paper concludes that large organisations confront conditions and contingencies which allow them to make certain choices about employment relations in ways that are not always available to small to medium sized organisations.

ln this paper, we discuss methodological issues that emerged as we worked through a small empirical research project, 'Engaging Aboriginal students in education through community empowerment'. Recent national policy statements (see, for example, MCEETYA 2000,. NBEET 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self-determination and improve educational outcomes. In keeping with these recommendations, our project aimed to challenge assimilationist frameworks and sought to 'empower' members of the local Aboriginal community through participation in the project. 'Research as dialogue' was a guiding principal and a primary aim was to listen actively to all key stakeholders in the remote community setting, particularly to lndigenous parents, students and teachers, in order to identify current strengths and concerns regarding the provision of culturally inclusive schooling. A proposed second stage of the project is to develop, on the basis of these consultations and in collaboration, community-based education projects that engage non-attending Aboriginal students. Here we discuss the consultative processes undertaken in stage one of the project, and critically analyse the difficulties as well as potential strengths of trying to form collaborative partnerships as researchers across cultural differences and with diverse community groups.

The 'rescuing' of Indigenous children (from their communities) through education, and the notions of assimilation associated with that, is an aspect of colonialism that has persisted into the so-called 'post-colonial' era. Recent national policy statements (eg. MCEETYA, 2000; NBEET, 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self determination and improve educational outcomes. In this paper, we report on the initial stage of a small empirical research project, Engaging Aboriginal Students In Education Through Community Empowerment.

'Research as dialogue' was a guiding principal and a primary aim was to listen actively to all key stake holders in the remote community setting, particularly to Indigenous parents, teachers and service providers, in order to identify current

strengths and concerns regarding the provision of culturally inclusive schooling; and then, to develop, on the basis of these consultations and in collaboration, community-based education projects that engage non-attending Aboriginal students.

In this paper, we critically analyse the difficulties as well as potential strengths of trying to form collaborative partnerships as researchers, across cultural differences and with diverse community groups. For example, what does 'acknowledging' very different cultural perspectives actually mean to/in this kind of research process? The ways in which relations of power amongst all parties are played out in/through such an approach is also opened up for scrutiny and further discussion.

Collectives and their interrelations are central to international law. Legal relations between collectives can be analysed with reference to the classic account of Hohfeld without reducing those collectives to mere aggregates of individuals and without recourse to the legal fiction of treating the collective, for example the state, as a quasi-individual. The rights of collectives have been widely if not conclusively explored within international law, but Hohfeld’s ‘field’ approach to legal relations enables the scrutiny of the range of relations, including immunities, liberties, powers, and disabilities, as well as claim-rights and the corresponding obligations in others. The main substantive topics for discussion are the legal relations of collective entities such as peoples and minorities, and closely related matters such as self-determination. Applying Hohfeldian analysis to international law highlights the centrality of international collective entities of which the state represents only one variety. The approach described here therefore takes account of the dethroning of the state within contemporary international law and contributes to the theorization of that development. Nearly one hundred years after its
first appearance, Hohfeld’s analytic scheme continues to generate insights for international law.

Nanostructured and ultra-fine grained metals have higher strength but extremely limited ductility compared to coarse grained metals. However, their ductility can be greatly improved by introducing a specific range of grain sizes in the microstructures. In the paper, multiscale unit cell approach (UCA) is developed and applied to predict the averaged stress-strain relations of the multiscale microstructure metals. The unit cell models are three-phase structured at different scale lengths of 100 nm, 1 μm and 10 μm with different volume fractions and periodic boundary conditions. The contributions of multi-scale microstructures to the macroscopic structural properties of metals are also studied using a analytic approach—two-step mean-field method (TSMF), where three microstructural parameters are introduced and thus mechanical properties such as strength and ductility are presented as a function of these parameters. For verification of these proposed numerical and theoretical algorithms, the structural properties of the pure nickel with three-grain microstructures are studied and the results from FEA and the proposed theory have good agreement.
