This note contributes to the discussion of decision problems with imperfect recall from an empirical point of view. We argue that, using standard methods of experimental economics, it is impossible to induce (or control for) absent–mindedness of subjects. Nevertheless, it is possible to test Gilboa's (1997) agent–based approach to games with imperfect recall. We implement his model of the absent–minded driver problem in an experiment and find, if subjects are repeatedly randomly rematched, strong support for the equilibrium prediction which coincides with Piccione and Rubinstein's (1997) ex ante solution of the driver's problem.

It is of importance to include the appropriate costs and outcomes when evaluating a health intervention. Sweden is the only country where the national guidelines of decisions on reimbursement explicitly state that costs of added life years should be accounted for when presenting health economic evaluations. The aim of this article is to, from a theoretical and empirical point of view, critically analyze the Swedish recommendations used by the Dental and Pharmaceutical Benefits Agency (TLV), when it comes to the use of costs of added life years in economic evaluations of health care. The aim is furthermore to analyze the numbers used in Sweden and discuss their impact on the incremental cost‑effectiveness ratios of assessed technologies. If following a societal perspective, based on welfare economics, there is strong support for the inclusion of costs of added life years in health economic evaluations. These costs have a large impact on the results. However this fact may be in conflict with ethical concerns of allocation of health care resources, such as favoring the younger part of the population over the older. It is important that the estimates of production and consumption reflect the true societal values, which is not the case with the values used in Sweden.

In Rajasthan state the ground waters of some areas like Ramganj-mandi, Morak, Barmer, Jaisalmer, Chittor and Udaipur etc. are susceptible from drinking point of view.To test the quality of groundwater in Chittor district 14, ground water samples were collected from various places and analyzed for pH, E.C., Fluoride and Nitrate parameters by standard methods (A.P.H. A., Washington, USA, 1995). The study revealed that none of the ground waters was found suitable completely from drinking point of view. Some are having electrical conductivity > 1.4 dS/m, some are having pH >8.5, some area having fluoride >1.5 ppm and some are having nitrate>45 ppm. These are the limits of various parameters permitted by various International authorities like Bureau of Indian Standard, Indian Council of Medical Research,world health Organization etc. for drinking waters. So, it is recommended to the residents of above areas to use water for drinking purpose only after reverse osmosis or adopting suitable method of removing excess of Fluoride and Nitrate for drinking water to avoid unwanted pathogenic diseases harmful for human health.

This paper focuses on the Information Packaging notion of linkhood and provides a structural definition of this notion for Greek. We show that a combination of structural resources – syntactic (left dislocation), morphological (clitic duplication) and phonological (absence of nuclear accent) – are simultaneously exploited to realize linkhood in Greek, a generalization that can be captured in a constraint-based grammar such as HPSG, which permits the expression of interface constraints. We assume Vallduví's (1992) approach to Information Packaging, and Engdahl & Vallduví's (1996) implementation of the latter in HPSG, but deviate from Vallduví's work in adopting Hendriks & Dekker's (1996) revised definition of linkhood that relies on non-monotone anaphora. From an empirical point of view, our approach directly accounts for the invariable association of Clitic Left Dislocated NPs with wide scope readings, as well as a number of systematic differences in felicity conditions between Clitic Left Dislocation and other apparently related phenomena (Topicalization and Clitic Doubling). From a theoretical perspective, our analysis departs from syntax-based notions of topichood or discourse-linking and supports a definition that unifies linkhood with other anaphora phenomena. As such, it arguably overcomes previously noted problems for Vallduví's treatment of links as the current-locus-of-update in a Heim-style file-card system.

Purpose of the study: The purpose of this study is to make sure that the Bird valley’s quarry water is suitable for drinking purposes or not and to monitor the seasonal variations in the physico-chemical parameters of this quarry water. Methodology: Water samples from the quarry were collected in clean and sterilized polyethylene bottles. Water samples were collected from different points and mixed together to get an integrated sample. Some of the selected physico-chemical parameters of the quarry water have been analyzed. Results were compared with standard limits of IS: 10500-2012. All the parameters were analyzed in the laboratory by using standard methods and techniques. Main Findings: As per the obtained results this quarry water contains a very large number of Coliforms detected in the months of September and December and in June month Coliform count was 33 CFU/ml. This overall result for coliform is making this quarry water unfit for domestic purposes. Applications of this study: This study helps us to understand the current condition of this quarry water and also enables us to know whether the quarry water is fit for drinking purposes. It also enables us to know whether this quarry water can be used for domestic purposes after the treatment. Novelty/Originality of this study: Bird valley’s quarry water has not been analyzed from this point of view till date. This study will help us to understand the present condition of the water.

This study empirically investigates the “relative tax gap hypothesis,” which posits that the greater the size of the relative tax gap, the greater the degree to which the U.S. Treasury must borrow from domestic and/or other credit markets and hence the higher the ex ante real interest rate yield on the Bellwether 30 year U.S. Treasury bond. The study uses the most current data available for computing what is referred to here as the “relative tax gap,” which is the ratio of the aggregate tax gap (the loss in federal income tax revenue resulting from personal income tax evasion) to the GDP level. For each year of the study period, the nominal value of the tax gap is scaled by the nominal GDP level and expressed as a percentage. The study period runs from 1982 through 2016, reflecting data availability for all of the variables. The estimation results provide strong support for the hypothesis. In addition, in separate estimations, evidence is provided that the relative tax gap also acts to elevate the ex ante real interest rate yield on Moody’s Baa-rated long-term corporate bonds. It logically follows, then, that to the extent that a greater relative tax gap leads to higher ex ante real interest rates, it may contribute to the crowding out of corporate investment in new plant equipment associated heretofore with government budget deficits per se.

Abstract Background and Purpose: This paper analyses the strategic aspects of knowledge management in organizations in Serbia, from the theoretical and empirical point of view. In its theoretical part, the paper analyzes the latest literature in the fields of knowledge management, relations between communications strategyes and knowledge management, generations of knowledge management and organizational culture. Design/Methodology/Approach: In its empirical part, the paper deals with determining the level of knowledge management in Serbian organizations through diffrent generations of knowledge management, as well as the problem with explicit and tacit knowledge management. The hypotheses were tested using data colleted from organizatons in Serbia via questionnaire, which consisted of 50 questions to examine five key factors in knowledge management. Results: The results showed that out of 41 indicators, only eight are rated positively. Results of t-test indicate significant distinctions within factors affecting the quality of knowledge management, as well as differences in quality of explicit and tacit knowledge management, therefore they confirmed both hypotheses. Conclusion: The knowledge management projects in organizations in Serbia are initiated, as well as that belonging to the first generation of knowledge management can be defined.

The idea prevailing in mainstream environmental law literature is that ex ante safety regulation is preferable to tort law remedies to deal with environmental issues. The main reason usually invoked to prefer ex ante regulation is that generally, tort law takes its part only after the harm has already been done; and that is considered not compatible with the objective of avoiding environmental harm. On the contrary, from the law and economics point of view, I will argue that tort law systems have some important properties that make it compatible with the goal of reducing environmental risks, and that it can be superior to ex ante regulation in avoiding environmental harm. Consequently, the purpose of this paper is drawing up a general framework to describe the relative advantages of tort law and their related conditions to deal with environmental harm.
