hyDRaCAT Spectral Reflectance Library: Hyperspectral Field Spectroscopy and Field Spectro-Goniometry of Siberian and Alaskan Tundra

hyDRaCAT Spectral Reflectance Library for tundra provides the surface reflectance data and the bidirectional reflectance distribution function (BRDF) of important Arctic tundra vegetation communities at representative Siberian and Alaskan tundra sites. The aim of this dataset is the hyperspectral and spectro-directional reflectance characterization as basis for the extraction of vegetation parameters, and the normalization of BRDF effects in off-nadir and multi-temporal remote sensing data. The spectroscopic and field spectro-goniometric measurements were undertaken on the YAMAL2011 expedition of representative Siberian vegetation fields and on the North American Arctic Transect NAAT2012 expedition of Alaskan vegetation fields both belonging to the Greening-of-the-Arctic (GOA) program. For the field spectroscopy each 100 m2 vegetation study grid was divided into quadrats of 1 × 1 m. The averaged reflectance of all quadrats represents the spectral reflectance at the scale of the whole grid at the 10 × 10 m scale. For the surface radiometric measurements two GER1500 portable field spectroradiometers (Spectra Vista Corporation, Poughkeepsie, NY, USA) were used. The GER1500 measures radiance across the wavelength range of 350-1,050 nm, with sampling intervals of 1.5 nm and a radiance accuracy of 1.2 × 10**-1 W/cm**2/nm/sr. In order to increase the signal-to-noise ratio, 32 individual measurements were averaged per one target scan. To minimize variations in the target reflectance due to sun zenith angle changes, all measurements at one study location have been performed under similar sun zenith angles and during clear-sky conditions. The field spectrometer measurements were carried out with a GER1500 UV-VIS spectrometer The spectrogoniometer measurements were carried out with a self-designed spectro-goniometer: the Manual Transportable Instrument platform for ground-based Spectro-directional observations (ManTIS, patent publication number: DE 10 2011 117 713.A1). The ManTIS was equipped with the GER1500 spectrometer allowing spectro-directional measurements with up to 30° viewing zenith angle by full 360° viewing azimuth angles. Measurements in central Yamal (Siberia) at the research site 'Vaskiny Dachi' were carried out in the late summer phenological state from August 12 2011 to August 28 2011. All measurements in Alaska along the North South transect on the North Slope were taken between 29 June and 11 July 2012, ensuring that the vegetation was in the same phenological state near peak growing season.

Bank restructuring and financial institution reform in Indonesia

The banking sector underwent drastic reform in post-crisis Indonesia. Bank restructuring, driven by IMF conditionalities, resulted in the exit of insolvent banks and ownership changes of major private banks. Through recapitalization and sales of government-held shares, foreign-owned banks emerged as leading actors in the place of business-group-affiliated banks. As part of the restructuring process, an exit rule was created. The central bank, which up to that time had been given only partial authority under the jurisdiction of the Minister of Finance, now gained a full range of authority over banks. The central bank's supervision system on banks, risk management systems at individual banks, and their efforts to build risk management capacities, began to function. This is totally different from the old financial institution under the Soeharto regime, where banks had no incentive to control risks, as the regime tacitly ensured their survival.

Imperfect Competition and Costly Screening in the Credit Market under Conditions of Asymmetric Information

This article provides an analysis of how banks determine levels of information production when they are in imperfect competition and there is a condition of information asymmetry between borrowers and banks. Specifically, the study concentrates on information production activities of banks in duopoly where they simultaneously determine intensity of pre-loan screening as well as interest rates. The preliminary model of this paper illustrates that due to strategic complementarities between banks, banking competition can result in inferior equilibrium out of multiple equilibria and insufficient information production. Policymakers must take into account the possible adverse effects of competition-enhancing policies on information production activities.

Bank Borrowing and Financing of Medium-sized Firms in Indonesia

The improvement of financial intermediation functions is crucial for a robust banking system. When lending, banks have to cope with such problems as information asymmetry and adverse selection. In order to mitigate these problems, banks have to product information and improve their techniques of lending. During the 1998 financial crisis, Indonesia's banking system suffered severe damage and revealed that the country's banking intermediation functions did not work well. This paper examines the financial intermediation functions of banks in Indonesia and analyzes the importance of bank lending to firms. The focus is on medium-sized firms, and "relationship lending", one of the bank lending techniques, is used to examine financial intermediation in Indonesia. The results of logit regressions show that the relationship between a bank and a firm affects the probability of bank lending. The amount of borrowing and collateral are also affected by a firm's relationship with a bank. When viewed from the standpoint of relationship lending to medium-sized firms, Indonesian banks cannot be criticized for any malfunction of financial intermediation.

Related Lending and Bank Performance: Evidence from Indonesia

After the Asian financial crisis of 1997, it was confirmed that banks lend to their related parties in many countries. The question examined in this article is whether related lending functions to alleviate the problems of asymmetric information or transfers profits from depositors and minority shareholders to related parties. The effects of related lending on the profitability and risk of banks in Indonesia are examined using panel data from 1994 to 2007 comprising a total of 74 Indonesian banks. The effects on return on asset (ROA) varied at different periods. Before and right after the crisis, a higher credit allocation to related parties increased ROA. In middle of the crisis, it turned to negative; and this has also been the case in the most recent period as the Indonesian economy has normalized. Effects of related lending on bank risk measured by the Z-score and non-performing loan is not clear. After undergoing bank restructuring, related lending has decreased and the profit structure of banks has changed.

Seasonal migration and micro-credit in the lean period : evidence from northwest Bangladesh

This paper investigates the relationship between access to micro-credit and temporary seasonal migration, an issue which is largely ignored in the standard rural-urban migration literature. Seasonal migration due to agricultural downturns is a common phenomenon in developing countries. Using primary data from a cross-sectional household survey from the northwest part of Bangladesh, this study quantifies the factors that influence such migration decisions. Among other results, we find that network effects play a significant role in influencing the migration decision, with the presence of kinsmen at the place of destination having considerable impact. Seasonal migration is a natural choice for individual suffering periodic hardship; however the strict weekly loan repayment rules of Micro-credit Institutes can have an adverse effect on this process, reducing the ability of borrowers to react to a shock. Our result suggests that poor individuals prefer the option of not accessing the micro-credit and opt for temporal seasonal migration during the lean period. The results have numerous potential policy implications, including the design of typical micro-credit schemes.

Impact of seasonality-adjusted flexible microcredit on repayment and food consumption : experimental evidence from rural Bangladesh

The mismatch between credit repayments and income seasonality poses a challenge for microfinance institutions (MFIs) working in developing countries. For instance, in northern Bangladesh, income and consumption downfalls during the lean season after the transplanting of major paddy crops are a serious threat to a household's economy. Poor landless agricultural wage laborers suffer the most owing to this seasonality as they face difficulties in smoothing their consumption. However, in designing microcredit products, MFIs do not usually provide flexibility or seasonal adjustment during the lean season. This is mainly because MFIs are afraid that such flexibility might break the repayment discipline of borrowers, resulting in higher default rates. We thus conducted a randomized controlled trial in 2011-12 in northern Bangladesh to empirically test whether seasonality-adjusted flexible microcredit leads to an increase in repayment problems for MFIs as well as whether it can increase and stabilize consumption of borrower households. Our results suggest no statistically discernible difference among the treatment arms in case of default, overdue amount, or repayment frequency. On the other hand, we find no positive impact of repayment flexibility on immediate food consumption during the period of seasonality, except for in-kind full moratorium treatment group. After a year of initial intervention, however, we see positive changes in food intake during the lean season. Thus, our preliminary results are in favor of seasonality-adjusted flexible microcredit.

The asset/liability structure of the Philippine banks and non-bank financial institutions in 2000s : a preliminary study for financial access analyses

Based on the consolidated statements data of the universal/commercial banks (UKbank) and non-bank financial institutions with quasi-banking licenses, this paper presents a keen necessity of obtaining data in detail on both sides (assets and liabilities) of their financial conditions and further analyses. Those would bring more adequate assessments on the Philippine financial system, especially with regard to each financial subsector's financing/lending preferences and behavior. The paper also presents a possibility that the skewed locational and operational distribution exists in the non-UKbank financial subsectors. It suggests there may be a significant deviation from the authorities' (the BSP, SEC and others) intended/anticipated financial system in the banking/non-bank financial institutions' real operations.

The innovation process of a privately-owned enterprise and a state-owned enterprise in China

This study compares the innovation process of a privately-owned enterprise and a state-owned enterprise in China using their patent data. Huawei and ZTE were selected for this study because they experienced the same historical environment in the same industry from the same region in China leaving their owner types as their critical difference. This study investigates the difference in the innovation process in R&D between a privately-owned and a state-owned enterprise by analyzing (1) domestic and international patent application pattern, (2) co-application and co-applicants, (3) knowledge accumulation inside Huawei and ZTE, and (4) knowledge spillover to domestic and foreign firms.

What best transfers knowledge? : capital, goods, and innovative labor in East Asia

This paper compares three knowledge carriers—trade, foreign direct investment (FDI), and inventors—as knowledge mediums, and investigates their effects on knowledge flow in East Asia from 1996 to 2010. Using patent citations as a proxy for knowledge flow, this paper shows that FDI and inventor mobility have positive effects on increasing patent citations in East Asia when the technological portfolios of two countries are less similar. While trade shows statistical significance, the effect is inconsistent according to the regression models.

Excess capital and bank behavior : evidence from Indonesia

The Indonesian banking sector has been restructured since Asian financial crisis and restored to soundness. The capital adequacy ratio (CAR) returned to a sound level; however, the average excess capital has become too high, while credit disbursement has remained low. This paper investigates the determinants of excess capital among Indonesian banks and its effects on credit growth during the 2000s. The results indicate that the determinants of excess capital vary widely depending on bank type. Return on equity (ROE) affects excess capital negatively among domestic banks, and the effect of non-performing loans is mixed, differing for various bank types. Excess capital affects credit growth positively, except among foreign banks.

Influence of cement properties in the reaction rate and mechanical behavior of concrete with high fl y ash content

The use of fly ash (FA) as an admixture to concrete is broadly extended for two main reasons: the reduction of costs that supposes the substitution of cement and the micro structural changes motivated by the mineral admixture. Regarding this second point, there is a consensus that considers that the ash generates a more compact concrete and a reduction in the size of the pore. However, the measure in which this contributes to the pozzolanic activity or as filler is not well defined. There is also no justification to the influence of the physical parameters, fineness of the grain and free water, in its behavior. This work studies the use of FA as a partial substitute of the cement in concretes of different workability (dry and wet) and the influence in the reactivity of the ash. The concrete of dry consistency which serves as reference uses a cement dose of 250 Kg/m 3 and the concrete of fluid consistency utilized a dose of cement of 350 Kg/m 3 . Two trademark of Portland Cement Type 1 were used. The first reached the resistant class for its fineness of grain and the second one for its composition. Moreover, three doses of FA have been used, and the water/binder ratio was constant in all the mixtures. We have studied the mechanical properties and the micro-structure of the concretes by means of compressive strength tests, mercury intrusion porosimetry (MIP) and thermal analysis (TA). The results of compressive strength tests allow us to observe that concrete mixtures with cements of the same classification and similar dosage of binder do not present the same mechanical behavior. These results show that the effective water/binder ratio has a major role in the development of the mechanical properties of concrete. The study of different dosages using TA, thermo-gravimetry and differential thermal analysis, revealed that the portlandite content is not restrictive in any of the dosages studied. Again, this proves that the rheology of the material influences the reaction rate and content of hydrated cement products. We conclude that the available free water is determinant in the efficiency of pozzolanic reaction. It is so that in accordance to the availability of free water, the ashes can react as an active admixture or simply change the porous distribution. The MIP shows concretes that do not exhibit significant changes in their mechanical behavior, but have suffered significant variation in their porous structure

How vague can your patent be? Vagueness strategies in U.S. patents

Patent claims defi ne the protection scope of the intellectual property sought by the patent applicant or patentee. Broad claims are valuable as they can describe more expansive rights to the invention. Therefore, if these claims are too broad a potential infringer will more easily argue against them. But if the claims are too narrow the scope of protection of the intellectual property is greatly reduced. Patent claims have to be, on the one hand, determinate and precise enough and, on the other hand, as inclusive as possible. Therefore patent applicants must fi nd a balance in the broadness of the scope defi ned by their claims. This balance can be achieved by the choice of words with a convenient degree of semantic indeterminacy, by the choice of modifi ers or other strategies. In fact, vagueness in patent claims is a desirable characteristic for such documents. A quantitative and qualitative analysis of a corpus of 350 U.S. patents provides a promising starting point to understand the linguistic instruments used to achieve the balance between property claim scope and precision of property description. To conclude, some issues relating vagueness and pragmatics are suggested as a line of further research.
