From Large Urban to Small Rural Schools: An Empirical Study of National Board Certification and Teaching Effectiveness Final Report

The National Board for Professional Teaching Standards (NBPTS) is a professional organization that provides national certification to teachers who apply for and meet the Board's standards of performance for "accomplished" educators. This study responds to a request from the NBPTS to analyze National Board certification among high school teachers in understudied subject areas and locales to help fill gaps in the research literature. The research team selected two new locales for this analysis, the Commonwealth of Kentucky and the Chicago public schools. Chicago, a racially and ethnically diverse city with a population of more than 2.8 million, has one of the largest urban school districts in the country. Kentucky, by contrast, is a largely rural state with some suburban and urban areas, including the Louisville/Jefferson County metro area, population 750,000. Together, these two locales encompass a full range of public school settings

Implementing Performance Measurement Innovations: Evidence From Government

Using data from a government-wide survey administered by the US General Accounting Office, we examine some of the factors influencing the development, use, and perceived benefits of results-oriented performance measures in government activities. We find that organizational factors such as top management commitment to the use of performance information, decision-making authority, and training in performance measurement techniques have a significant positive influence on measurement system development and use. We also find that technical issues, such as information system problems and difficulties selecting and interpreting appropriate performance metrics in hard-to-measure activities, play an important role in system implementation and use. The extent of performance measurement and accountability are positively associated with greater use of performance information for various purposes. However, we find relatively little evidence that the perceived benefits from recent mandated performance measurement initiatives in the US government increase with greater measurement and accountability. Finally, we provide exploratory evidence that some of the technical and organizational factors interact to influence measurement system implementation and outcomes, often in a complex manner

Tracking indoor basato su beacon: Trauma Tracker come caso di studio

L'obiettivo del progetto è la realizzazione di un sistema di tracciamento della posizione in ambienti indoor utilizzando i beacon partendo dai requisiti di Trauma Tracker, che richiede un sistema in grado di determinare la posizione corrente di una persona che si muove con un dispositivo android all'interno di un ambiente in cui sono stati posizionati dei beacon. Nel primo capitolo viene definito il tracciamento indoor, con esempi e le principali caratteristiche. Nel secondo vengono trattate le principali tecnologie utilizzate. Il terzo capitolo approfondisce la tecnologia dei beacon Bluetooth. Il quarto capitolo introduce Trauma Tracker e gli obiettivi del progetto. Il quinto capitolo si descrive la progettazione e l'implementazione di un'applicazione per il monitoraggio della posizione e dei beacon nelle vicinanze utilizzando la libreria Android Beacon Library, con i test e i risultati ottenuti. Infine nell'ultimo capitolo espone come è stata eseguita l'implementazione del suo core di tracciamento all'interno di Trauma Tracker

Alternative Information Sources and Information Asymmetry Reduction: Evidence From Small Business Debt

We examine whether more sophisticated accounting methods (in the form of accrual accounting) interact with other information sources to reduce information asymmetries between small business borrowers and lenders, thereby lowering borrowers׳ probability of loan denial and cost of debt. We find that higher third party credit scores, but not the use of accrual accounting, decrease the likelihood of loan denial. However, firms using accrual accounting exhibit statistically lower interest rates after controlling for many factors associated with the cost of debt. Further, the interest rate benefits from accrual accounting are greatest when the borrower׳s credit score is low and/or the length of its banking relationship with the lender is short. This evidence indicates that accrual accounting can benefit small business borrowers, but that the information contained in third-party credit scores and obtained through ongoing banking relationships can substitute for the incremental information provided by accrual accounting

Tackling hepatocellular carcinoma with individual or combinatorial immunotherapy approaches.

Abstract Hepatocellular carcinoma (HCC) is the third leading cause of death from cancer globally. Indeed, there is a single drug approved as first-line systemic therapy in advanced unresectable HCC, providing a very limited survival benefit. In earlier stages, 5-year survival rates after surgical and loco-regional therapies are extremely variable depending on the stage of disease. Nevertheless, HCC is considered an immunogenic tumor arising in chronically inflamed livers. In such a scenario, immunotherapy strategies for HCC, in particular combinations including cancer vaccines, may represent a key therapeutic tool to improve clinical outcome in HCC patients. However, a lot of improvement is needed given the disappointing results obtained so far

Discrimination, social capital, and financial constraints: the case of Viet Nam

This paper examines the relationship among gender, social capital, and access to finance of micro, small,and medium enterprises in the manufacturing sector in Viet Nam. Our dataset is from the 2011, 2013, and2015 results of the Micro, Small, and Medium Enterprise Survey in Viet Nam. Using the Heckman technique to control for sample selection bias, the estimates do not provide evidence for discriminationagainst female-owned enterprises in the formal lending market. Specifically, female entrepreneurs havea higher probability of getting a loan and they pay lower interest rates in comparison with male entrepreneurs. No discrimination in formal credit markets may arise from the preference for informal loansover formal loans as entrepreneurs tend to borrow informal loans before applying for formal ones.Further analysis shows that social capital could facilitate loan applications: firms that have a closer relationship with government officials and other business people can get loans of longer duration
