An inventory model with reliability in an imperfect production process
No full textThe paper analyzes an economic manufacturing quantity (EMQ) model with price and advertising demand pattern in an imperfect production process under the effect of inflation. If the machine goes through a long-run process, it may shift from in-control state to out-of-control state. As a result, the system produces imperfect items. The imperfect items are reworked at a cost to make it as new. The production of imperfect quality items increases with time. To reduce the production of the imperfect items, the systems have to more reliable and the produced items depend on the reliability of the machinery system. In this direction, the author considers that the development cost, production cost, material cost are dependent on reliability parameter. Considering reliability as a decision variable, the author constructs an integrated profit function which is maximized by control theory. A numerical example along with graphical representation and sensitivity analysis are provided to illustrate the model. �� 2011 Elsevier Inc. All rights reserved
On the Effectiveness of Central Bank Intervention in the Foreign Exchange Market: The Case of Slovakia 1999-2007
No full textThis paper investigates the effect of the National Bank of Slovakia's (NBS) intervention in the SKK/EUR foreign exchange market from 1999 through 2007 (the time period covering Slovakia's preparation for EU accession and euro adoption) on the level of the SKK/EUR exchange rate. The study asks 2 questions. Did the National Bank of Slovakia's sterilized interventions in the market for the koruna and the euro from 1999-2007 have an effect on the level of the koruna's exchange rate with the euro? If so, for how long did this effect last? High-frequency, intraday data on both foreign exchange rates and sterilized NBS interventions in the market for the koruna and the euro is analyzed using OLS to this end. The frequency of this data allows the author to counteract the perennial endogeneity problem of studies on central bank intervention. 3 conclusions are offered. First, NBS intervention from 1999-2007 had a statistically significant impact on the level of the SKK/EUR exchange rate in the short-term. Second, this short-term effect was statistically insignificant after 2 hours and 40 minutes had passed following each NBS intervention trade, implying the effect of intervention dissipates over-time. Third, given the short-term impact of NBS intervention, this tactic could be considered an expensive policy tool for influencing the level of a country's exchange rate, as intervention can require a central bank to draw down substantially on its foreign exchange reserves
Corollary of Marine Eco-system Sustainability by Addressing the Issues of Bycatches
No full textThe issue of bycatch in fisheries sector has been a major concern for the marine biologists over few decades in terms of conservation of marine eco-system and sustainability of the fisheries sector and marine biodiversity. Bycatch generally include species of little commercial importance, which in most cases is dumped overboard either into the sea or after reaching the fish landing sites. The article discusses the ecological, economic, legal, social influences, and the importance in addressing the issue of bycatch. The concept of bycatch is relatively new in the horizon in Indian perspective as it is often considered major issues by developed nations which are characterised by highly mechanised and industrialised fisheries. The problem of bycatch is seen as the depletion of this food source for local consumption and therefore a threat to livelihoods and food security in general and it has environmental, economic, socio-cultural impacts. The adverse effects of by-catch can be mitigated through commercialisation of bycatch and making profits from the sale of bycatch, opening up of new markets for bycatch species or products, uses of fishmeal as feed in the poultry and aquaculture industries and application of bycatch reduction devices (BRDs). The revamping the present monitoring system used to collect fisheries data, strengthening technical know-how, bringing effective policy intervention, efficient co-management, and sincere and honest efforts in reducing bycatch and discards may provide a considerable impact towards sustainability of marine eco-system
Teacher' Attitudes towards Emergency Remote teaching: challenges in Indian academe
No full textThe present study intends to explore the challenges of teachers' attitudes during Emergency Remote Teaching (ERT) in higher educational institutions (HEIs) during the COVID-19 pandemic. It also investigates whether teacher age is in any way a mediating factor for teacher attitude. The transformative sequential research design of mixed methods was employed on a random sample of 90 participants pooled ever since the lockdown had been announced in India (March 23, 2020). The qualitative data (text), thus obtained, has been categorized into six challenges, sorted into categories, and transformed into quantitative data (code) for the Chi-square test and interpretation. The Chi-square test confirms no significant association between challenges in ERT identified by teachers' attitudes and teachers' ages. The study discusses the challenges felt by teachers and the probable ways of mitigation them for running remote teaching during this pandemic
Rural to Urban Migration and Network Effects in an Extended Family Framework
Get PDFLiterature on migration and network effects suggests that the rate of migration is positively related to the extent or degree of personal and community level networks potential migrants have at the destination. However in this particular paper it is shown that when the decision making unit is the extended family and there is a minimum wage induced Harris-Todaro type job rationing in the urban sector having greater numbers of previous migrants at the urban end does not necessarily lead to more migration from the hinterland. This counter intuitive result is generated as a consequence of juxtaposing an extended family framework with urban equilibrium unemployment in the model. A larger stock of previous migrants at the urban end has a positive effect on new migration which comes specifically through a greater flow of remittance income from the migrants to their rural counterparts - the two households comprising the extended family. The increased remittance income provides a positive stimulus to migration as it relaxes the migration cost constraints facing the extended family. On the other hand limited jobs in the urban sector and the resultant job rationing implies that a greater number of previous migrants also crowds out job opportunities for the new ones thus simultaneously reducing incentives to migrate. The direction of the net effect however depends on the economic characteristics of the extended family and the initial employment conditions in the urban sector.Harris-Todaro, Migration, extended family framework
