the optimal ordering policy in a dcf analysis for deteriorating items when trade credit depends on the order quantity abstract in this paper an inventory system for deteriorating items under the conditions of using the discounted cash flows dcf approach to the permissible to delay payment will be considered as a matter of fact the supplier usually is willing to provide the retailer a permissible delay of payments if the retailer orders a large quantity as a result we consider that the delay in payments depends on the quantity ordered that is when the order quantity is less than that at which the delay in payments is permitted the payment for the item must be made immediately otherwise the fixed trade credit period is permitted this paper incorporates all concepts of a dcf approach and the trade credit linked to ordering quantity and develops a new inventory model for deteriorating items to generalize jaggi and aggarwal int j prod econ 34 1994 151

credit financing in economic ordering policies of deteriorating items this paper presents the economic ordering policies of deteriorating items in the presence of trade credit using a discounted cash flows dcf approach a dcf approach permits a proper recognition of the financial implication of the opportunity cost and out of pocket costs in inventory analysis it also permits an explicit recognition of the exact timing of cash flows associated with an inventory system a comprehensive sensitivity analysis has also been done

optimal economic ordering policy with deteriorating items under different supplier trade credits for finite horizon case abstract this paper develops and solves a general finite horizon trade credit economic ordering policy for an inventory model with deteriorating items under inflation and time value of money when shortages are not allowed the time horizon is divided into different cycles each of which has its own demand rate and its own trade credit period offered from the supplier to his retailer so that the retailer should pay his supplier before or after the end of the permissible trade credit of that cycle up to the end of the trade credit of a cycle the retailer is free of charge but he is charged on an interest for those items not being sold before this end the retailer can also earn the interest of the money from the generated sales revenue in any cycle by depositing such revenue into an interest bearing account the objective of the retailer is then to minimize his net total relevant costs a closed form of this net total cost is derived and the resulting model is solved then rigorous mathematical methods are used to show that under some seemingly possible conditions there exist a unique vector of the relevant decision variables that solve the underlying inventory system a numerical example which shows the applicability of the theoretical results is given

power struggle dispute and alliance over local resources analyzing democratic decentralization of natural resources through the lenses of africa inland fisheries summary this paper is based on a global review of fisheries decentralization programs co management in sub saharan africa partly challenging the current narrative but in line with experience in other sectors e g forestry the review shows that the outcomes of these decentralizations have not been systematically positive in most cases fisheries co management failed to improve governance but simply altered the distribution of power and responsibility amongst the different stakeholders in this new political landscape poorly designed reforms have enabled a variety of usual and new local actors to advance their own agendas often at the detriment of the direct end users fisherfolk

property rights regimes and natural resources a conceptual analysis revisited summary more than two decades ago schlager and ostrom 1992 developed a conceptual schema for arraying property rights regimes that distinguishes among diverse bundles of rights the conceptual framework has profoundly influenced research on natural resource governance common property and community resource management however currently natural resource governance has changed dramatically challenging the applicability of the conceptual schema there are now many more social actors involved in resource management than the local communities at the focus of original analysis additionally resource management increasingly provides access to various kinds of benefits from outside the immediate context including indirect benefits such as payments for environmental services and results based payments for redd these changes demand addition of new property rights to the original framework this paper updates the conceptual schema in reaction to changes in natural resource governance proposing three specific modifications on the focus of use rights control rights and authoritative rights to come up with a framework that distinguishes eight types of property rights we apply the framework to three purposefully selected governance interventions in china and laos that include the provision of indirect benefits in addition to the direct benefits derived by local people from natural resources the empirical application shows how contemporary governance changes may not lead to local people s outright dispossession since they continue to possess direct use rights to natural resources however local people may be excluded from control and authoritative rights which are exercised exclusively by state agencies and international actors the latter make available indirect benefits to local people which may or may not translate into use rights in the sense of policy based entitlements the empirical insights suggest the possibility of a wider trend of compensated exclusions in natural resource governance

replenishment and pricing policy for deteriorating items taking into account the time value of money abstract a deteriorating inventory model taking into account the time value of money is developed for a deterministic inventory system with price dependent demand this study applies the discounted cash flows dcf approach for problem analysis a heuristic approach is presented to derive the near optimal replenishment and pricing policy that tries to maximize the total net present value profit a numerical example is implemented to illustrate the theory

a review of trade credit literature opportunities for research in operations abstract trade credit arises when a buyer delays payment for purchased goods or services its nature has predominantly been an area of inquiry for researchers from the disciplines of finance marketing and economics but it has received relatively little attention in other domains in our article we provide an integrative review of the existing literature and discuss conflicting study outcomes we organize the relevant literature into seven areas of inquiry and analyze four in detail trade credit motives order quantity decisions credit term decisions and settlement period decisions additionally we derive a detailed agenda for future research in these areas

can geographical indications modernize indonesian and vietnamese agriculture analyzing the role of national and local governments and producers strategies summary this paper investigates the way geographical indications gis are implemented by national and local governments in indonesia and vietnam the two states are active at all stages of gi development from the selection of the products candidates for gi registration to the supervision of the gi implementation thanks to the involvement of national experts from public agencies in the establishment of the codes of practices cop they are able to push for the substitution of traditional local techniques with good practices i e mostly those recommended by research centers worldwide thus they put gis at the service of agricultural modernization when gis apply more conventionally to specific products based on traditional know how however the implementation of the cops and thus the achievement of this objective of modernization depend on the perceived interest of producers in the whole gi dynamic indeed the cases studied in indonesia and vietnam highlight the variable level of participation of local producers in the gi in the four studied cases the cops are mainly based on expert knowledge which differs from the actual practices of farmers and processors moreover gis are implemented in order to create or reinforce reputations rather than legally protecting preexisting ones for these two reasons producers motivation to invest in gi certification is weak which makes difficult the necessary collective involvement in both countries the involvement of local governments in gi construction and management modifies the situation thanks to their knowledge of local situations and stakes they are more likely than national experts to identify the most strategic supply chains at local level enable participatory approaches in gi construction and facilitate the involvement of local producers in the gi managing group but if competences have been given to local governments in the indonesian and vietnamese legal frameworks the distribution of roles between central and provincial governments in gis are not clearly enough specified the nature and the importance of local public intervention differ from one case to another finally this paper recognizes the legitimacy of state intervention in gi development at least as long as producers awareness of gis is still low however this state intervention should not only let enough space for producers in gi governance but also design a frame for arousing their interest and adhesion and for facilitating their collective involvement that may be facilitated by a concrete and clearly established decentralization of competences in national policies

legal pluralism and decentralization natural resource management in mali summary much recent work on decentralized natural resource management has focused on the institutional arrangements that shape the balance of powers between central and local governments it has given comparatively less attention to relationships between local government and community level institutions in mali decentralization has superimposed modern legal institutions on community institutions the ambiguous relationships between them can undermine both the authority of nascent local governments and the performance of customary institutions legal pluralism the coexistence and interaction of multiple normative orders with different sources of legitimacy and authority helps explain the dynamic nature of local institutions under decentralization this article examines the experiences of three malian communities with decentralized natural resource management one maintains autonomy from government another engaged its local government and a third negotiated a multi stakeholder agreement a local convention they demonstrate that crafting workable relationships between communities and local government requires a pragmatic approach to negotiating and institutionalizing political space for innovation in self governance

impacts of access and benefit sharing on livelihoods and forest case of participatory forest management in ethiopia the introduction of participatory forest management pfm may involve the exclusion of previous forest users from accessing forest resources this is the case for pfm in the two ethiopian pioneer sites dodola and chilimo that represent two distinct pfm approaches in ethiopia this paper analyses how pfm after controlling pre pfm differences affects members of forest user groups fugs and non members total annual incomes forest incomes expenditures and livestock asset holdings income and asset data were collected from 635 randomly selected households data were analysed using propensity score matching models results show that in dodola where commercial timber harvest is allowed the introduction of pfm means that fugs have higher livestock assets and forest income than non members the average total income and the expenditure for members and nonmembers however were not significantly different in chilimo site the result is the opposite the introduction of pfm means that fug members have lower total incomes and assets than non members based on our findings we recommend that the pfm scaling up approaches in ethiopia which currently allow fugs only subsistence use from forest resources need to be revised

an eoq model with partial backordering and advance payments for an evaporating item abstract in the classic economic order quantity model the purchasing cost of an order is paid at the time of its receipt in some cases retailers ask purchasers to pay all or a fraction of the purchasing cost in advance and may allow them to divide the prepayment into several equal sized parts in this paper an economic order quantity model for an evaporating item with partial backordering and partial consecutive prepayments is developed with a real case study of a gasoline station real numerical examples illustrate the proposed model and the solution method

stepping into formal politics women s engagement in formal political processes in irrigation in rural india summary gender quotas decentralization of irrigation management and reliance on mgnrega for labor provision challenge the traditional patriarchal canal management system by institutionalizing women as formal decision makers and members of the irrigation labor force in northern india based on a survey of 592 women in rural himachal pradesh this paper quantitatively analyses how these policies affect women s engagement in formal political processes results indicate that factors from the private and individual domains influence female participation in formal political processes most importantly india s gender inclusive policies provide women with the opportunity to legitimately engage in formal political processes governing resource management

recentralizing while decentralizing how national governments reappropriate forest resources summary decentralization initiatives have been launched in the majority of developing countries but these rarely lay the foundations necessary to reach decentralization s purported efficiency and equity benefits this paper uses a comparative empirical approach to show how central governments in six countries senegal uganda nepal indonesia bolivia and nicaragua use a variety of strategies to obstruct the democratic decentralization of resource management and hence retain central control effective decentralization requires the construction of accountable institutions at all levels of government and a secure domain of autonomous decision making at the local level

from exclusion to participation turning senegal s forestry policy around abstract a century of centralized forestry policies has excluded senegal s forest villagers from charcoal production and marketing policies have given access to marketing and labor opportunities to urbanbased merchants who hire guinean migrant laborers while forest villagers neither produce nor consume charcoal commercial production is cutting forests on which villagers rely in 1993 progressive forestry agents ushered in a new participatory forestry code but this new policy may not be equitable nor beneficial and it risks adding control over village labor for forest management to the long list of forest service controls locally accountable representation local decision making powers and simple local management enabling policies could diminish these risks

an eoq model with noninstantaneous receipt and exponentially deteriorating items under two level trade credit abstract this paper considers the impact of the trade credit policy on the classical economic production quantity epq model for an item subject to exponential decays essentially this study focuses on an exponentially deteriorating item under the conditions of the retailer receiving the supplier trade credit and providing the customer trade credit simultaneously so as to minimize the average total cost a theorem is developed to determine the optimal replenishment policies the main contribution to literature is the inclusion of the latter type of payment delay finally through numerical examples sensitive analysis shows the influence of key model parameters

supply chain networks with corporate financial risks and trade credits under economic uncertainty abstract the focus of this paper is to provide an analytical framework which can be used to investigate how financial risks affect the values of interconnected supply chain firms from a network perspective and how financial risks affect the supply chain firms profitability as well as the cash and credit transactions in particular we develop a variational inequality equilibrium model in conjunction with capital asset pricing model capm and the net present value npv to determine the optimal supply chain prices profits and implicit equity values of supply chain firms under financial risks and economic uncertainty we illustrate the analytical framework with computational studies which yield interesting managerial implications to the following questions 1 how do financial risks and economic uncertainty affect the values of interconnected supply chain firms from a network perspective 2 how do financial risks and economic uncertainty affect the supply chain firms profitability as well as the cash and credit transactions 3 how does the effect of financial risks change under different competition scenarios

review of inventory systems with deterioration since 2001 abstract this paper presents an up to date review of the advances made in the field of inventory control of perishable items deteriorating inventory the last extensive review on this topic dates back to 2001 goyal s k and giri b c recent trends in modeling of deteriorating inventory european journal of operational research 134 1 16 since then over two hundred articles on this subject have been published in the major journals on inventory control indicating the need for a new review we use the classification of goyal and giri based on shelf life characteristics and demand characteristics contributions are highlighted by discussing main system characteristics including price discounts backordering or lost sales single or multiple items one or two warehouses single or multi echelon average cost or discounted cash flow and payment delay

natural resources and decentralization in nicaragua are local governments up to the job abstract both decentralization and natural resource management literature suggest that natural resources could benefit from the redistribution of centralized management authority yet neither has sufficiently examined the processes already underway in numerous developing countries to decentralize resource management from central to municipal government authorities this study reviews the role of 21 local governments in forest management in nicaragua it finds that most interventions are economically motivated and that three key factors are needed for local governments to be good resource managers capacity incentive and long term commitment these three factors are part of a process in which civil society can play a critical role

uncertainty and the theory of international trade in long run equilibrium abstract we consider a country with two factors and two industries each of which faces technical and price uncertainty entrepreneurs choose outputs in order to maximize the expected utility of profits they also draw factor payments and purchase consumption goods after the uncertainty isresolved they enter and exit from an industry according to whether participation there increases their expected utility within this model the validity of the propositions of neoclassical trade theory depends on how the entrepreneurs entry decisions are affected by parameter changes via their roles as risk bearers consumers and factor owners

complexities of decentralization in a globalizing world in many developing countries decentralization programmes for natural resource management aim to induce incentives for sustainable resource management at the local level the effectiveness of such programmes has however suffered from weak property rights to the resource and by the presence of externalities growing economic integration among countries has exacerbated these problems by increasing the exposure of local user groups to commercial actors interested in resource extraction in this paper the interplay of decentralization and globalization in affecting environmental outcomes and community welfare is analysed through a game theoretic model of community firm interactions the results highlight the complexities of policy design first by raising the extractive value of the resource globalization may lead to communities negotiating resource extraction agreements with firms second with a lack of effective state enforcement of community resource rights communities may be unable to assume de facto ownership over the resource while commercial actors succeed in exploiting resources without community consent no single policy option provides a panacea to counteracting these negative effects instead a mix of policies combining incentive payments along with the provision of more secure property rights and poverty alleviation is shown to have the potential to improve both environmental outcomes and community welfare

impact of trade credit and inflation on retailer s ordering policies for non instantaneous deteriorating items in a two warehouse environment with the advent of better technologies in manufacturing and retail industry consumer beliefs and needs have been altered supermarkets are expected to sell fresh products in good conditions which have a longer shelf life or do not begin to deteriorate immediately termed known as non instantaneous deteriorating items this characteristic is now usually observed in almost all food stuffs fashionable items electronic products among others in order to sustain in the retail sectors the managers are moving forward to store these items in warehouses moreover due to increasing competition in business world supplier offers a permissible delay in payments to retailer in order to increase demand this encourages the retailer to order a large quantity which in turn entitles the organization to rent out an additional storage space considering the importance of such a scenario the present research work develops a two warehouse inventory model for non instantaneous deteriorating items with permissible delay in payments under inflationary conditions shortages are allowed and partially backlogged since customers willingness to wait decreases over time the objective of this paper is to determine the retailer s optimal replenishment policies that maximize the present worth of total optimal profit per unit time finally the proposed inventory model has been validated with the help of numerical example sensitivity analysis of the optimal solution with respect to key parameters of the inventory system has been also presented which provides important managerial implications

decentralization institutional ambiguity and mineral resource conflict in mindanao philippines based on an analytical framework that builds on theories of incremental institutional change this article interrogates the relationship between decentralization and mineral resource conflict in the philippines here efforts to decentralize control over mineral resource wealth have resulted in a highly ambiguous institutional arena wherein heterogeneous actor coalitions are attempting to influence trajectories of institutional change and the associated distribution of mineral wealth on the ground this institutional renegotiation produces a diverse range of conflicts emerging on top of these institutional struggles are local elected politicians which raises important concerns over elite capture of the decentralization process

an inventory model with deteriorating items under inflation when a delay in payment is permissible abstract this study develops an inventory model for initial stock dependent consumption rate when a delay in payment is permissible in the inventory model shortages are not allowed the effect of the inflation rate deterioration rate initial stock dependent consumption rate and delay in payment are discussed in the study mathematical models are also derived under two different circumstances i e case i the credit period is less than or equal to the cycle time for settling the account and case ii the credit period is greater than the cycle time for settling the account besides expressions for an inventory system s total cost are derived for these two cases moreover a computational procedure and gino lasdon et al acm transactions mathematical software 4 1978 34 50 are proposed to obtain the optimal order size and cycle time the results can help managers determine the optimal total cost finally a numerical example demonstrates the applicability of the proposed model

re election incentives and deforestation cycles in the brazilian amazon abstract despite expansive research on amazonian deforestation and its drivers the role of local politics is not well understood using a panel data set that combines municipal level deforestation and election data from 2002 to 2012 i estimate the effect of an incumbent mayor running for re election on deforestation rates in election periods i find that deforestation rates increase 8 10 in election years when an incumbent mayor runs for re election an amount equivalent to four percent of the total forest lost since the 2004 elections electoral deforestation cycles do not appear to be driven by changes in agricultural policy implementation and activity but are linked to corruption and campaign finance suggesting that weak institutional constraints facilitate electoral manipulation of forest resources this phenomenon is not likely limited to amazonian forests re election incentives could very well lead to misallocation of other natural resources in alternate geographies

governance institutions resource rights regimes and the informal mining sector regulatory complexities in indonesia summary this study examines how shifting resource governance regimes affect labor inequities in the small scale mining sector in indonesia it focuses on the implications of governance decentralization processes and mining regulation reforms for indigenous and migrant populations who rely on informal unlicensed mining for income in central kalimantan while the findings illustrate the territorially uneven impacts of recent reforms they highlight how dominant paradigms that prioritize the enforcement of property rights schemes have contributed to problems of livelihood insecurity and poor environmental governance the article urges for more nuanced attention to contested articulations of power as well as local resource rights and institutional arrangements to assist rural communities in reversing marginalization

optimal price discounting and lot sizing policies for perishable items in a supply chain under advance payment scheme and two echelon trade credits abstract many researchers have assumed that a retailer announces price discount to motivate market sales when he has competition in markets unanticipated surplus in inventory or change in the production run of a product but in real life situations there are retailers who announce price discount offer under advance payment ap scheme prior to the selling period due to the advancement of internet and on line money transactions the ap scheme is common and useful to decrease the estimation error in demand and to increase the market sales when the items are arrived to the inventory the priority will be given to the customers who use ap scheme this paper considers a supply chain where the supplier provides the retailer a full trade credit period for payments whereas the retailer offers the partial trade credit to his customers i intend to develop an economic order quantity eoq based model with perishable items in order to investigate the retailer s inventory system as a cost minimization problem under ap scheme and two echelon trade credit option mathematical theorems are developed to determine optimal price discounting and lot sizing policies and a lot of managerial phenomena are obtained through numerical examples

participatory processes in the soy conflicts in paraguay and argentina abstract within emerging environmental conflicts different participatory processes have developed as alternatives to the top down models that have dominated policy making in this paper we focus on conflicts over the expansion of soy production we analyze three issues related to top down vs bottom up participatory processes and how they affect the proposals coming out of these processes who counts as stakeholder the role of social movements what counts as participation the role of mobilization and who has power to select stakeholders and issues make decisions and influence preferences to explore these issues we present a case study of two parallel participatory processes in rural areas of paraguay and argentina one of these the roundtable on responsible soy is top down created by large agri business multinationals and international conservation ngos with the support of the governments in the region and has focused on establishing criteria for responsible soy the other is bottom up self organized by peasant and civil society organizations and focused on stopping soy expansion and promoting food sovereignty the findings highlight the potential of bottom up processes to promote true agricultural sustainability while at the same time emphasizing the need for more research on grassroots participatory processes and their potential and limitations in different contexts

inventory models with variable lead time and present value the figures for inventory make up a huge proportion of a company s working capital because of this we formulated the optimal replenishment policy considering the time value of money to represent opportunity cost in this article we provide a mixed inventory model in which the distribution of lead time demand is normal to consider the time value first the study tries to find the optimal reorder point and order quantity at all lengths of lead time with components crashed to their minimum duration secondly we develop a method to insure the uniqueness of the reorder point to locate the optimal solution finally some numerical examples are given to illustrate our findings

planning for shortages net present value analysis for a deteriorating item with partial backlogging abstract this paper develops inventory models to help answer strategic questions concerning whether planning for shortages offers financial benefits a production inventory system producing a deteriorating product in batches at a finite production rate with partial backordering is considered customers pay a deposit when placing a backorder backordered items receive a discount on the sales price as lost sales may lead to customers not returning the demand rate may depend on the fraction of lost sales we develop a cash flow based profit maximising net present value npv model without the inventory cost parameters commonly used in this context unit holding cost unit backorder cost unit deterioration cost and unit lost sales cost the model finds the optimal inventory policy just like npv models that discount the traditional parameters but has the advantage of not needing to estimate the value of the traditional parameters it is shown that in models based on discounting the traditional parameters the parameters are not exogenously determinable but are non trivial functions of non financial endogenous system parameters such as the production rate annual demand rate and backorder rate extensive numerical experiments illustrate how cash flow npv models provide insights into the value of planning for shortages and strategic choices about the design of the production inventory system it also provides insight into the classical problem of how to interpret unit backorder cost and unit lost sales cost the study indicates that these insights cannot be reliably obtained from npv models based on discounting unit backorder costs and unit lost sales costs

production and inventory model using net present value using the net present value is the standard methodology in theoretical analysis and the most frequently used method for making financial decisions however net present value is rarely used in production and inventory decisions the main reasons appear to be the complexity of the formulae and the robustness of the eoq model we investigate the general multiproduct multistage production and inventory model using the net present value of its total cost as the objective function a power of two heuristic gives us a near optimal solution to this problem if the base period is fixed or varied the solution based on the best power of two heuristic will be within 6 2 or 2 1 of the optimal this result is surprisingly similar to models using the long term average cost the average cost does not reflect the time value of money does this mean that decisions based on average cost are significantly inferior to those based on net present value the answer is quite surprising if we include discounted production cost in the holding cost it turns out that the decision based on average cost is only 9 6 in terms of the net present value of the total cost worse than the decision based on the net present value however the reorder interval based on the average cost could be much longer than that derived using net present value this result shows that average cost is a good approximation to the net present value when the demands are deterministic

effects of inflation and time value of money on an inventory model with time dependent demand rate and shortages abstract in a recent paper datta and pal investigated the effects of inflation and time value of money on an inventory model with linearly increasing demand and finite shortage cost however their models are formulated under the assumption of equal inventory carrying time during each replenishment cycle in this paper we redevelop the models of datta and pal by relaxing this assumption and modifying their mathematical formulations our models can be applicable to both growing and declining markets with general continuous time dependent demand rates numerical examples are provided to illustrate the developed models

holding costs under push or pull conditions the impact of the anchor point holding costs are traditionally determined from the investment in physical stock during a cycle an alternative approach instead derives holding costs from net present value npv functions it is known that applying both frameworks to the same system can lead to different holding cost valuations but little explanation has been offered by introducing the anchor point in a model this paper shows for four different systems that traditional holding cost models implicitly assume pull conditions while current npv approaches model push conditions this explains in part the differences between the methods it is shown that the anchor point concept allows the construction of npv models under pull conditions giving results in better correspondence with traditional models the traditional framework is restricted to pull conditions and important considerations could be easily overlooked leading to wrong valuations of holding costs npv seems superior as such considerations are automatically incorporated the application to multi echelon inventory systems provides interesting insights on the roles of echelon stocks and lead times and offers potential for future research

an integrated vendor buyer inventory model with order processing cost reduction and permissible delay in payments trade credit plays an important role in financing for many businesses and industries for the buyers purchased inventory can be considered to be financed in whole or in part with permissible delay in payments during the purchasing process on the other hand both the vendor and buyer take part in order processing cost reduction by applying information technologies such as edi electronic data interchange the order processing cost can also be reduced by adding certain capital investments and this will affect the lot size decisions this article develops an integrated inventory model to determine the optimal inventory policy under conditions of order processing cost reduction and permissible delay in payments and shows that the total annual variable cost function possesses some kinds of convexities a solution procedure is provided to determine the optimal order policy finally a numerical example is presented to illustrate the solution procedure

local government fiscal reform in developing countries lessons from kenya abstract local government fiscal reform is emerging clearly as a major development issue of the 1990s as central governments of developing countries cut back their budget growth in response to economic reality and donor pressure many are attempting to tap the underutilized potential of local authorities to help meet rising service demands drawing on a case study of the local finance system in kenya and that country s attempts at reform the challenging economic institutional and political issues that must often be confronted in such reform efforts are highlighted

a deterministic eoq model with delays in payments and price discount offers abstract it is the purpose of this paper to model the retailer s profit maximizing strategy when confronted with supplier s trade offer of credit and price discount on the purchase of merchandise generally retailers have to face many types of demands for different kinds of goods in real situation retailers have to correlate between the selling price and supplier s trade offer keeping in mind profit maximization strategy in the proposed model all increasing deterministic demands are discussed analytically numerically and graphically in the environment of permissible delay in payment and discount offer to the retailer

in search of alternatives pro poor entrepreneurship in community forestry abstract community forestry is quite likely the most prominent form of development intervention in the present era it has gained momentum since the 1970s and now covers more than 25 per cent of the total forestlands globally however the introduction of commercialisation into community forestry controlled by private capital has not only undermined the livelihood requirements of poor people but also swiftly deteriorated forest conditions by unfolding the nature of commercialisation in community forestry in nepal this article argues that pro poor entrepreneurship models of producing forest resources through a partnership between poor people and community groups could be an appropriate alternative to develop economic opportunities and forest conservation

on a finite horizon production lot size inventory model for deteriorating items an optimal solution abstract a generalized production lot size inventory model for deteriorating items over a finite planning horizon is considered the demand production and deteriorating rates are assumed to be known and continuous functions of time shortages are allowed and completely backlogged the conditions under which the system total cost attains its unique global minimum are derived an example which illustrate the applicability of theoretical results is also introduced

retailer s optimal replenishment decisions with credit linked demand under permissible delay in payments abstract usually it is assumed that the supplier would offer a fixed credit period to the retailer but the retailer in turn would not offer any credit period to its customers which is unrealistic because in real practice retailer might offer a credit period to its customers in order to stimulate his own demand moreover it is observed that credit period offered by the retailer to its customers has a positive impact on demand of an item but the impact of credit period on demand has received a very little attention by the researchers to incorporate this phenomenon we assume that demand is linked to credit period offered by the retailer to the customers this paper incorporates the concept of credit linked demand and develops a new inventory model under two levels of trade credit policy to reflect the real life situations an easy to use algorithm is developed to determine the optimal credit as well as replenishment policy jointly for the retailer finally numerical example is presented to illustrate the theoretical results followed by the sensitivity of various parameters on the optimal solution

an inventory model for deteriorating items with shortages and time varying demand abstract a deterministic inventory system for items with a constant deterioration rate is studied demand varies in time and it is assumed that it follows a power pattern shortages are allowed and backlogged the ordering cost the holding cost the backlogging cost the deteriorating cost and the purchasing cost are considered in the inventory management an approach is proposed to minimize the total cost per inventory cycle this cost depends on two decision variables the time at which the inventory level falls to zero and the length of the scheduling period numerical examples illustrate the theoretical results

leadtime management in a periodic review inventory system a state dependent base stock policy we examine a single item periodic review inventory system with stochastic leadtimes in which a replenishment order is delivered immediately or one period later depending probabilistically on costly effort the objective is to determine a joint inventory policy and effort choice strategy that minimizes the expected total costs our analytical and computational analysis suggests that i a state dependent base stock policy is optimal ii the optimal effort strategy is such that the marginal cost of effort is equal to the value of immediate delivery and iii the cost impact of leadtime reduction can be very large we also provide some counter intuitive results compared with the traditional multi period newsvendor model

voter response to conservation policies in madagascar summary international conservation groups pour millions of dollars into developing countries to help preserve resources and set conservation priorities but critics argue that affected populations are often excluded from the decision making process in 2003 many in the international community praised the president of madagascar for his pledge to more than triple the area under protection this paper examines how voting patterns in the president s re election bid differed in communities affected by these policies the results suggest less support for the president in regions with new protected areas but that these policies would be unlikely to change the outcome of an election
