Progress in Understanding Color Maintenance in Solid-State Lighting Systems

In this paper, progresses of color maintenance, also known as color shift, in solid-state lighting(SSL) systems are thoroughly reviewed. First, color shift is introduced and a few examples are given from different real-life industrial conditions. Different degradation mechanisms in different parts of the system are also explained. Different materials used as lenses/encapsulants in light-emitting diode(LED)-based products are introduced and their contributions to color shift are discussed. Efforts put into standardization, characterizing, and predicting lumen maintenance are also briefly reviewed in this paper.

Simulation Models for Evaluation and Selection of Depreciation Policy for Agricultural Companies in the Republic of Bulgaria

In the present paper, the results from research on the influence of criteria （factors） such as depreciation method, materiality threshold, and inflation rate on the selection of depreciation policy are shown. The research has been carried out with the help of specifically devised simulation models. The simulation is realized in accounting for the unevenness of money in time and the profitability of the company, the tax rates for corporate tax, and the inflation rate. The models have been devised after analyzing methodology issues, related to depreciation policy and investigating current practices in its implementation in specific agricultural companies in present-day Bulgaria. It has been determined that there is a clear-cut relation between the profitability of the companies and the materiality threshold and depreciation method chosen. The main conclusion is that when the companies develop their depreciation policy, at ceteris paribus they should select higher materiality thresholds and diminishing balance depreciation methods due to the inequality of money in time, the acceleration of obsolescence, and the inflation processes.

Depreciation of Millennials in Organizational Settings: What Underlying Factors in a Traditional Values Context

This study sets out to examine:In a traditional value context,which variables are related to the attitude of depreciation of Millennials by GX in an organizational setting?Through a Factorial Correspondence Analysis,it is postulated that three factors would be at the origin of the depreciation of Millennials in an organizational environment.The analysis shows a correlation between the 10 variables analyzed,but two factors emerge:the GY’s ability to invest or build and the GY’s commitment to starting a household.The hypothesis that there are three latent factors underlying the data analyzed is therefore rejected.

Supporting Innovation Through a Mechanism of Accelerated Depreciation in the Republic of Uzbekistan

The state plays a paramount role in the development of the national economy. In this development process, the state with direct levers, using the available tools as state financial support, banks systems, and tax policy, can provide incentives to identify areas for managing business entities. Obviously, one of the main levers of the state policy is a tax policy. Tax policy plays a crucial role in supporting innovation activities, which in turn provide sustainable economic growth for both the economic entities and the state. Whereas, due to guaranty of sustainable production line in the market economy, the economic entity always needs additional financial resources that ensure the renewal of fixed assets. The present paper focuses on the variation of calculations of the depreciation fund in the Republic of Uzbekistan. Regarding to both the tax rates and interval of the residual value of fixed assets, without attracting financial flows, the economic entities can update fixed assets, which on the same time increases the tax payments to the state budget in case of Uzbekistan.

The Straight-Line Depreciation Method Used by Selected Companies and Educational Institutions in the Philippines

The straight-line method in computing for depreciation expense is the prevailing method used in the Philippines. This paper aims to determine the rationale behind the use of this method. The objective of the study is to determine the length of time within which the depreciation method is used, reasons in using the method, the rate of depreciation used by the companies, and the effects of the depreciation expense on their operating expenses. It also determines if the companies＇ decisions to use the straight-line method are influenced by the factors mentioned by Reynolds （196 I）----expected amount of services over the life of assets, the amount and timing of operating costs, the decline in the physical efficiency of the assets, and the rate of return--and if they considered capital investments and tax reduction in using this method. The study shows that companies and educational institutions use the straight-line method of computing depreciation expenses, because it is easy to use in computing the depreciation expenses, in comparing with previous years＇ computations, and in keeping track of the expenses. It is also convenient for tax administration and financial reporting. The rate of depreciation used varies, because the companies and educational institutions use their past experiences in determining the life of fixed assets. The percentage of depreciation to the operating expenses also varies. The companies and educational institutions adhered to the factors mentioned by Reynolds （1961） in choosing the straight-line method of depreciation. The companies did not consider reduction of tax in using the straight-line method.

The Cause Analysis of College Student Human Capital Depreciation in China

Human capital depreciation can be divided into stock depreciation and utility depreciation, which will cause the waste of human capital investment, and let human capital value fail to fully embody, affecting social development. In the critical time of China facing population aging and economic transformation, as the new human capital of the labor market, college students play an important role to social and economic development. Therefore, preventing and mitigating their human capital depreciation is necessary. This article focus on human capital investment and configuration stage, analyze the influence of unreasonable human capital investment system and separate labor market segmentation system to college student human capital depreciation, and put forword the corresponding countermeasures.

China＇s Exchange Rate System——A Policy Perspective

Like most developing countries, China has been adopting a multiple exchange rate regime in its attempt to maintain control and order while liberalizing transactions in the sphere of trade, non-trade and crossborder fund flows. From a very rigid, highly centralized regime in 1979, China has by now advanced to a relatively flexible system under which the official rate, the swap rate, and the ＂free＂ market rate coexist. The tight control of international transfer of funds has also been progressively relaxed, as different parties gain increasing freedom to acquire foreign exchange. The Chinese economy has been reasonably stable during the Asian financial crisis. Although China maintains the exchange rate stability, in near future a real appreciation of the RMB must be necessary element in global adjustment. More flexible exchange rate will give more advantages for Chinese economy.

Depreciation of the Economic Value of Historic Properties

Historic properties are cultural, historic and/or architectural heritage assets that may have legal or statutory protection due to their cultural and economic importance. Often the real estate with a certain historical value is privately owned, and the owners request the estimation of the value of these properties, either for advisory purposes, or to gage the property for the purpose of lending, or for other purposes. In this research, the authors, within the framework of the cost approach, analyze the peculiarities of estimating the depreciation of the economic value of real estate properties with historic/architectural value. The emphasis is placed on the methods of estimating the physical depreciation and it is recommended to apply them depending on the condition of the construction and the use or non-use of the real estate for a long time. Based on a case study, the authors explain the paradox of the value of real estate with advanced age located in compact historical areas.

Depreciation factor equation to evaluate the economic losses from ground failure due to subsidence related to groundwater withdrawal

Subsidence due to groundwater withdrawal is a complex hydrogeological process affecting numerous cities settled on top of fluviolacustrine deposits. The discrete spatial variation in the thickness of these deposits, in combination with subsidence due to groundwater withdrawal, generates differential settlements and aseismic ground failure (AGF) characterized by a welldefined scarp. In cities, such AGF causes severe damages to urban infrastructure and considerable economic impact. With the goal of arriving to a general criterion for evaluating the economic losses derived from AGF, in the present work we propose the following equation: ELi = PVi*DFi. Where PVi is the value of a property “i”, and DFi is a depreciation factor caused by structural damages of a property “i” due to AGF. The DFi is calculated empirically through: . This last equation is based on the spatial relations of coexistence and proximity of property polygons and the AGF axis. The coexistence is valued as the quotient of the affectation area divided by the total area of the involved property;and the proximity to the AGF axis is expressed as the inverse of the perpendicular distance from the centroid of the property polygon to the AGF axis. The sum of these terms is divided by two to determine the percentage that affects the property value (PVi). These equations are relevant because it is the first indicator designed for the discrete assessment of the economic impacts due to AGF, and can be applied to real estate infrastructure from either urban or rural areas.

Policy Recommendations to Prevent Financial Risks Caused by Speculative Capital Flows

There are two inaccuracies to the common belief that hot money flows into China through international trade: "hot money" and "trade channels". First, China’s domestic financial market is still at the initial stage of development, and foreign exchange control has put barriers to entry and exit of overseas capital. Strictly speaking, the short-term highly liquid "hot money" does not exist in China, and is referred to as long-term speculative capital in this paper. Second, such capital does not come from trade alone. International trade is only part of corporate business operations, and a more reasonable and complete description is that "overseas capital flows into China through foreign-funded enterprises". Through analysis of the inflow channels, this paper estimates that the stock of long-term speculative capital between 1999 and 2006 stands at almost US$ 400 billion. The year 2006 saw an increase of US$ 98.09 billion, of which US$ 35.4 billion was formed through international trade, which equals to roughly 20% of trade surplus that year. But this does not mean that 20% of trade surplus is long-term speculative capital.

Accounting Practice in Agricultural Enterprises in Turkey

Agricultural sector is vital for human beings, it provides stuffto the other sectors and it contributes to employment considerably. A large proportion of the exportation of Turkey is made from the agricultural products. Thereby it can be said that the agricultural sector is one of the main sectors contributing to the economy of the country considerably. But it＇s known that the sector is affected by some risks and uncertainities such as： sector＇s being made-up of family-owned companies, its being sensitive to the weather conditions, the long process of buying products, the work＇s being seasonal, self-consumption, the difficulty in accounting the cost, unrecorded agricultural transactions. Within this context to determine the sector＇s contribution to the country＇s economy clearly is related to recording the agricultural transactions properly and choosing the realistic methods and implementations. But despite the importance that agricultural transactions carry, the rules of recognition of the related transactions stay at an area that is not much worked on by the operators and researchers till the accounting postulates published. One reason for this is the sector, which is generally made-up of family-owned companies, and the operators have a general view point that accounting is not the purpose of management but taxation. In recent years with the international development of economy and technology, it＇s seen that big investors have entered the sector. With the changed system of trade, agricultural sector became a strategic sector. In this respect, in-depth data and information, acquired from accounting system, became very important. In this study, the principles and the rules that are applied in the agricultural transactions within the frame of international accounting standards are explained. In which account group should be the biological assets that are agricultured and agricultural products according to their qualities, which accounts are used, and how they are recognitioned are explained. In this context, in the study the examples which are related with the implementation are given over annual plants and prennial plants. The differences between the accounts that are used, are mentioned over by these examples.

A Conceptual Framework for Commercial Property Price Indexes

The paper studies the problems associated with the construction of price indexes for commercial properties that could be used in the System of National Accounts. Property price indexes are required for the stocks of commercial properties in the Balance Sheets of the country and related price indexes for the land and structure components of a commercial property are required in the Income Accounts of the country if the Multifactor Productivity of the Commercial Property Industry is calculated as part of the System of National accounts. The paper suggests a variant of the capitalization of the Net Operating Income approach to the construction of property price indexes and uses the one hoss shay or light bulb model of depreciation as a model of depreciation for the structure component of a commercial property.

A Three-Stage Stochastic Dynamic Pricing Game Model Affected by New Products into the Market

In real-life marketing, a common phenomenon is that the prices of current product will have been cut down even the new product has not gone into market yet. Thus, it is very important for merchant to set the strategy which can make the excepted revenue maximum. So, this paper constructs a three-stage stochastic dynamic pricing game model for analyzing the influence of the uncertainty of entry timing of the new products on pricing of products being sold. By analyzing of the pricing strategy, there are big differences in the predictions of new product going into market between merchant and customers;the merchant will adopt cutting price for promotion strategy to reduce negative influence of the new products on the demand of the products sold now. Otherwise, the merchant will adopt the strategy of maximizing current period’s profit.

Understanding Corporate Costs and Sustainability

This material aspires to start to evaluate every sorts of corporate cost form the view of modem corporation. Traditionally, there are material costs together with depreciation, salary cost, personal cost, financial cost, and other cost. For managerial purposes, this paper distinguishes between standard and nonstandard cost. Special attention is devoted to responsibility costs and division of costs. In this modem age, however it is a question whether the understanding of cost should be so narrow and limited to money that a corporation spends during the course of its production, or whether it should include also the constitution of negative externalities--the damages the company causes to the environment. Therefore, the final part of this contribution part deals with function of cost and attempts to provide an evaluation of basic sorts of cost in modem corporation from a broader societal perspective.

EXPLORING THE VALUE OF INSTALLED BASE:PRICING INFORMATION GOODS UNDER VALUE DEPRECIATION AND CONSUMER SOCIAL LEARNING

While last decade has witnessed a rapid growth of digital economy, there is limited understanding in literature on whether the conventional wisdom on pricing strategy still holds for information goods. On one hand, information goods, similar to durable goods, are subject to value depreciation; on the other, they differ from traditional goods in negligible marginal cost and the sensitivity to social influences. This paper develops a two-period, game-theoretic model to investigate optimal pricing strategy of information goods. On one dimension, two different depreciation mechanisms （self- and time-depreciation） are considered; on the other, two prevalent pricing schemes （perpetual licensing and subscription-fee models） are studied. We obtain closed-form solutions in all scenarios. Our findings suggest that vendors of time-depreciation information goods should adopt subscription-fee model to attract early adopters and exploit social influences, while the vendors of self-depreciation information goods should strategically balance between depreciation and social influences. Interestingly, as social influences become strong enough, the difference between pricing schemes diminishes and the tradeoff between candidate strategies vanishes. We also extend the model to static pricing in which the vendor commits to future price. We discover that the superiority of subscription-fee model might be overturned under static pricing. Our results above also imply that building consumer feedback and interaction systems could be helpful for minimizing the potential loss of a suboptimal pricing scheme.

Coping and rumination as predictors of posttraumatic growth and depreciation

Purpose: The present study examined the joint impact of coping and rumination after trauma on posttraumatic growth (PTG) and posttraumatic depreciation (PTD) based on the PTG model. Methods: A cross-sectional study was conducted between October 2017 and May 2018. A sample of 253 individuals who had experienced a traumatic event in the last two years, was included. Participants completed an online self-reported survey, including demographic variables, trauma characteristics, the German Posttraumatic Growth and Depreciation Inventory — Expanded, the Brief COPE Inventory, and the Event Related Rumination Inventory. An analysis of correlation, a principal component analysis and hierarchical regression analyses were conducted. Statistical analyses were undertaken on SPSS (version 25.0;IBM, New York, USA). Results: After controlling for the effects of personal and trauma characteristics, self-sufficient coping and socially supported coping were found to favor the emergence of PTG. Event-related and recent deliberate rumination were positively related to PTG. Avoidant-focused coping and recent intrusive rumination were positively associated with PTD. Overall, the final models accounted for 46% and 58% of the variance in PTG and PTD. Conclusion: Our findings confirm the PTG model and support the central role of deliberate rumination, self-sufficient coping and socially supported coping in the development of PTG. Our results indicate that a similar model of PTD with comparable influencing factors can be assumed: if the individual is stuck in ongoing intrusive rumination and uses more avoidance-focused coping, it might lead to more reports of PTD.

Depreciation of the Yen and its Impact on the Chinese Economy——Interview with Yu Yongding,Director,Institute of World Econnomics and Politics,CASS

Since early January this year,the Japanese yen has beendepreciating steadily, from 128 and 129 to 130 yen perdollar,which is the lowest in the last 38 months. It seemsJapan is finally playing its exchange rate card after fail-ing to revive its econmy through interest rate cuts andexpanding govemment expenditure. Do you think this"exchange rate card" can be the savior for Japan’seconomy? Is the yen depreciation the best choice to pre-vent its economy from falling further?

Optimization of depreciation subsidy policy strategies for electric two-wheelers for improving traffic safety

To improve the traffic safety of electric two-wheelers(ETW),China has promulgated ETW standardization policies.This policy requires local governments to take measures to guide the illegal ETWs out of use.Governments have implemented a depreciation subsidy scheme to encourage users to scrap illegal ETWs early.When designing the subsidy scheme,effectively improving the ETWs’traffic safety at the road network level while saving government expenses is essential for the sustainable implementation of the policy.This study proposes an optimization method for depreciation subsidy design incorporating traffic safety evaluation.Based on the policy scheme,this study formulates a risk assessment model for the ETW traffic network to characterize the effect of the subsidy on improving safety.Then,we use the bi-level programming approach to model the subsidy strategy design problem.The upper-level problem reflects the goal of policymakers to maximize safety improvement and minimize government expenses.The lower-level problem describes the route choices of ETW users.The optimal subsidy design under different safety-expense trade-offs is analysed based on the Nguyen and Dupuis network and a real network extracted from Changsha City in China.The results show that specific subsidy schemes effectively improve road safety without a large government spending.When themarket price or service life of ETWs increases,the government spending on the same safety goal increases.The government should comprehensively consider the safety effect of financial expense and the situation of the local ETW market before selecting reasonable subsidy strategies.
