Firewood consumption in a Nepali village

Abstract: People's dependence on firewood as a primary source of energy is causing serious deforestation problems in many developing countries. Reliable information on firewood consumption rates is needed to develop afforestation plans and to control deforestation. This study compares three methods used to determine firewood consumption in a Nepali village. Cultural and environmental factors that affect firewood consumption in the village are also examined. Theweight survey proved to be the most accurate method used. The less precisedaily recall andannual recall surveys overestimated actual firewood consumption by factors of 1.76 and 1.95, respectively. Overestimates are attributed to both physical and social factors. In view of the good agreement between daily and annual recall surveys, and the much greater ease of conducting the latter, annual recall surveys are recommended as the most practical method of monitoring firewood consumption rates. Validating the survey with occasional weighed measurements is suggested as a means of improving accuracy.

A review of missing values handling methods on time-series data

Abstract: Missing values becomes one of the problems that frequently occur in the data observation or data recording process. The needs of data completeness of the observation data for the uses of advanced analysis becomes important to be solved. Conventional method such as mean and mode imputation, deletion, and other methods are not good enough to handle missing values as those method can caused bias to the data. Estimation or imputation to the missing data with the values produced by some procedures or algorithms can be the best possible solution to minimized the bias effect of the conventional method of the data. So that at last, the data will be completed and ready to use for another step of analysis or data mining. In this paper, we will explain and describe several previous studies about missing values handling methods or approach on time series data. This paper also discuss some plausible option of methods to estimate missing values to be used by other researchers in this field of study. The discussion's aim is to help them to figure out what method is commonly used now along with its advantages and drawbacks.

Fairness in performance evaluation and its behavioural consequences

Abstract: A recent paper in Accounting and Business Research by Lau et al. (2008) offers systematic evidence to explain whether managers’ perceptions on fairness of performance evaluation procedures affect attitudes such as job satisfaction; and if it does, the different behavioural processes involved. Our paper re‐examines Lau et al.’s model and hypotheses to assess the external validity of their findings, based on a very different sample of managers. Drawing on recent organisational justice literature, it further develops the model and examines the potential interaction effects of fairness of performance evaluation procedures and other variables on job satisfaction. Finally, it extends the outcome variable to include manager performance. Using survey responses from 165 managers, supported by 24 interviews, drawn from three major organisations in the manufacturing and financial services sectors, we find that Lau et al.’s results on the indirect effects of fairness of performance evaluation procedures on j...

Performance measurement in Indonesia: The case of local government

Abstract: Purpose: The purpose of this paper is to investigate the implementation of performance measurement systems (PMSs) in Indonesian local government (ILG) using Smart PLS Couched within an institutional theory framework, it explores a conceptual model developed to explain the hypothesised relationships between technical and organisational factors and the development and use of performance indicators and accountability practices Design/methodology/approach: Surveys were sent to senior finance officers in all local governments (457) across Indonesia with a response rate of 214 percent being achieved Smart PLS was used to assess the quality of the data and analyse the research model proposed Findings: Findings revealed that ILGs developed performance indicators more to fulfil regulatory requirements than to make their organisation more effective and efficient As a way of increasing the success of PMS implementation management commitment through good leadership was found to be a major contributor Coercive pressure from central government impacted on the result as did normative isomorphism by way of widespread training by universities (and others) and the subsequent sharing of this knowledge

Unsupervised primaquine for the treatment of Plasmodium vivax malaria relapses in southern Papua: A hospital-based cohort study.

Abstract: Background Primaquine is the only licensed drug for eradicating Plasmodium vivax hypnozoites and, therefore, preventing relapses of vivax malaria. It is a vital component of global malaria elimination efforts. Primaquine is efficacious when supervised in clinical trials, but its effectiveness in real-world settings is unknown. We aimed to determine whether unsupervised primaquine was effective for preventing re-presentation to hospital with vivax malaria in southern Papua, Indonesia. Methods and findings Routinely-collected hospital surveillance data were used to undertake a pragmatic comparison of the risk of re-presentation to hospital with vivax malaria in patients prescribed dihydroartemisinin-piperaquine (DHP) combined with primaquine versus those patients prescribed DHP alone. The omission of primaquine was predominantly due to 3 stock outages. Individual clinical, pharmacy, and laboratory data were merged using individual hospital identification numbers and the date of presentation to hospital. Between April 2004 and December 2013, there were 86,797 documented episodes of vivax malaria, of which 62,492 (72.0%) were included in the analysis. The risk of re-presentation with vivax malaria within 1 year was 33.8% (95% confidence Interval [CI] 33.1%–34.5%) after initial monoinfection with P. vivax and 29.2% (95% CI 28.1%–30.4%) after mixed-species infection. The risk of re-presentation with P. vivax malaria was higher in children 1 to <5 years of age (49.6% [95% CI 48.4%–50.9%]) compared to patients 15 years of age or older (24.2% [95% CI 23.4–24.9%]); Adjusted Hazard Ratio (AHR) = 2.23 (95% CI 2.15–2.31), p < 0.001. Overall, the risk of re-presentation was 37.2% (95% CI 35.6%–38.8%) in patients who were prescribed no primaquine compared to 31.6% (95% CI 30.9%–32.3%) in those prescribed either a low (≥1.5 mg/kg and <5 mg/kg) or high (≥5 mg/kg) dose of primaquine (AHR = 0.90 [95% CI 0.86–0.95, p < 0.001]). Limiting the comparison to high dose versus no primaquine in the period during and 12 months before and after a large stock outage resulted in minimal change in the estimated clinical effectiveness of primaquine (AHR 0.91, 95% CI 0.85–0.97, p = 0.003). Our pragmatic study avoided the clinical influences associated with prospective study involvement but was subject to attrition bias caused by passive follow-up. Conclusions Unsupervised primaquine for vivax malaria, prescribed according to the current World Health Organization guidelines, was associated with a minimal reduction in the risk of clinical recurrence within 1 year in Papua, Indonesia. New strategies for the effective radical cure of vivax malaria are needed in resource-poor settings.
