Research on the effectiveness of educational inputs, particularly research on teacher effectiveness, typically overlooks teachers’ potential impact on behavioral outcomes, such as student attendance. Using longitudinal data on teachers and students in North Carolina I estimate teacher effects on primary school student absences in a value-added framework. The analysis yields two main findings: First, teachers have arguably causal, statistically significant effects on student absences that persist over time. Second, teachers who improve test scores do not necessarily improve student attendance, suggesting that effective teaching is multidimensional and teachers who are effective in one domain are not necessarily effective in others.

Abstract Noble Research Institute initiated a cow/calf best management practices (BMP) and marketing program in 2000. Over time, the Integrity Beef Alliance program has matured into a producer-run stand-alone Alliance that has received much favorable attention in the industry. The objectives of the program are: 1.) implement BMP’s, 2.) increase selling weights of calves, 3.) increase calf quality and uniformity, 4.) improve marketing efficiencies, 5.) utilize producer records for improvement, and 6.) educate producers to use of BMP’s. This program has developed stringent protocols that must be adhered to throughout the calf production phase. Protocols and requirements center on cow and bull genetics, herd health, preconditioning criteria, and record keeping. Producers who complete all required documentation and pay an annual membership fee are allowed to sell their calves through a value added calf sale, receive a letter of certification to provide to potential direct market buyers, or market through Superior Livestock Video utilizing the Integrity Beef Alliance logo. Through the utilization of financial and production records, members are able to benchmark themselves against other similar operations in the program and against their own performance over time to determine areas of needed improvement and areas of efficiency. Compared with the 2008 NAHMS data, producers have averaged a 28.6 kg increased weaning weight. Many producers have indicated a higher increase in weaning weight compared to their previous protocols. The program has grown from 11 producers in 2005 to 51 members in 2018.

Due to the high amount of low-quality hardwoods harvested during selection cuts, the forest industry has been facing a decline in profit margins. One possible solution for utilizing the low-quality raw material is the production of extracts. The objective of this work was to estimate to what extent the inclusion of betulin in the traditional wood products portfolio could extend the profitability of a hardwood value chain. The profitability of a selection cut was assessed from the sawmill perspective, followed by an evaluation of the potential financial gain of producing betulin. Finally, the inclusion of betulin in a value chain was assessed. Results showed that the profitability of selection cuts was very low in some forest stands. The sensitivity analysis demonstrated that, among selected costs and revenues, profit was more sensitive to variations in the value of coproducts. If a fraction of coproducts volume was used to extract betulin, it would be sufficient to generate enough revenue to offset the total costs; however, a major constraint was the small size of the current betulin market, with annual sales not exceeding 1000 kg. Despite that, results demonstrate the potentially strong contribution of high value added extracts to the profitability of the forest value chain.

Surveys of teacher preparation program (TPP) completers have become one widely used measure for program accountability and improvement, yet there is little evidence as to whether perceptions of preparation experiences predict the workforce outcomes of teachers. In the present study, we use statewide completer survey data from North Carolina to assess whether perceptions of preparation quality and opportunities to learn during teacher preparation predict completers’ value-added estimates, evaluation ratings, and retention. We perform multiple analyses to address validity concerns—that is, selection into TPPs, sorting into K-12 schools, simultaneity in survey and outcome measures, and differential survey response rates across TPPs. Results are not always consistent across these analyses; however, evidence suggests that completer perceptions are modestly associated with teacher effectiveness and retention. Continued research can further address validity concerns and build a body of evidence on completer perceptions and teacher outcomes.

Quasi Experiment

Chetty, Friedman, and Rockoff (2014a, b) study value-added (VA) measures of teacher effectiveness. CFR (2014a) exploits teacher switching as a quasi-experiment, concluding that student sorting creates negligible bias in VA scores. CFR (2014b) finds VA scores are useful proxies for teachers' effects on students' long-run outcomes. I successfully reproduce each in North Carolina data. But I find that the quasi-experiment is invalid, as teacher switching is correlated with changes in student preparedness. Adjusting for this, I find moderate bias in VA scores, perhaps 10–35 percent as large, in variance terms, as teachers' causal effects. Long-run results are sensitive to controls and cannot support strong conclusions. (JEL H75, I21, J45)

For more than 150 years postcards all over the world have three main roles: a value-added receipt for a postage payment in advance, a means of celebrating and promoting national heritage and a collection of pieces. But above all, the postage stamp is a true ambassador of human history, culture and civilization, because its form and function give it freedom of movement and the ability to transmit information all over the world. Through this paper, the authors want to open a series of presentations of what has given valuable, over time, the philately of civilization and human culture and which is reflected in philatelic collections. There are fractions of images - as far as a stamp can be - with people and places, with flowers and landscapes, animals and protected habitats, with what we want to remain alive in the memory of our descendants - as an essential component of environmental policy And sustainable development.

Value added is a measure of the increase in wealth of a company. The question posed in this paper, is whether there was a change over time; firstly in the percentage of added value by companies as a proportion of sales and secondly in the distribution of the added value between the different stakeholder groups.The ratio VA/sales and the VA distribution ratios were calculated for three samples:A full sample from 1990 to 2002, consisting of all the listed South African companies preparing a value added statement; A constant sample of 36 companies that existed from 1990 to 2002; and A constant sample of 55 companies that existed from 1994 to 2002.Although a slight downward trend was found in VA/sales from 1997/1998, there is not enough evidence to infer that there was a change over time in VA/sales as the differences in the central location for at least two years were not significant.It was determined that there was only one distribution ratio in each constant sample with a significant difference in the central locations between at least two of the years. These ratios were retention/VA for the constant sample from 1990 to 2002 and depreciation/VA for the constant sample from 1994 to 2002.The change over time in depreciation was probably caused by the change in accounting treatment for amortisation of intangible assets. Retention is a balancing figure – the leftovers after the other allocations have been done – it can therefore be expected that this ratio will be influenced by the changes in all the other allocations. The general prosperity of the company and the economy will also influence retention, as the total value added will change accordingly and that will determine what is being left for retention in the company. As the growth in the GDP increased during the period under review, it was no surprise to find an increase in the ratio retention/VA.
