Characteristics of learning computer-controlled mechanisms by teachers and students in a common laboratory environment

Growing popularity of robotics education motivates developing its didactics and studying it in teacher training programs. This paper presents a study conducted in the Department of Education in Technology and Science, Technion, in which university students and school pupils cope with robotics challenges of designing, building and operating computer-controlled mechanisms. The university students were involved in developing robot prototypes and related instructional materials, and assisted in teaching robotics and guiding projects to middle school and high school pupils. The study focused on behaviors of the two groups of learners and aimed to elicit and analyze typical characteristics of learning in the developed robotics environment. We collected qualitative data on learning through robot design and experimentation activities and, by means of the ground theory method, elicited and analyzed typical behavioral characteristics of students’ and pupils’ learning: self-confidence, help, collaboration, interest, seriousness, self-dependence, learning effort, responsibility, coping with learning pressure, learning through observation, and perseverance. As found, the behavior characteristics evolve in the course of robotics studies and their evolution can give indication on the development of the desired competences.     

Absorptive capacity, its determinants, and influence on innovation output: Cross-cultural validation of the structural model

The main purpose of this study is to provide stronger quantitative evidence in the field of organizational absorptive capacity research by using a more direct measure of absorptive capacity and a wide range of variables in a cross-nationally tested structural model. The results show that there exist two kinds of absorptive capacity: demand-pull and science-push. Their most important determinants proved to be internal R&D, training of personnel, innovation co-operation and attitude toward change. Both kinds of absorptive capacity are positively related to product and process innovation output. Therefore, absorptive capacity is to be given more attention in the future research and innovation policy considerations.     

When Kamay Met Hill: Organisational Ethics in Practice

The Kamay and Hill insider trading conviction in Australia highlights many of the issues and problems involved in the prevention, detection and prosecution of insider trading. The case uniquely highlights how ethical behaviour is instilled at home, in school and in society, and the need for ethical responsibility at the personal and organisational level to complement legal rules and enforcement. We use the Kamay and Hill case to explore the reasons behind the failure of the traditional top-down approach to insider trading prevention, where institutional ethical codes of conduct largely reflect and rely upon national rules, norms, and regulation. We propose a bottom-up approach to ensure that individual and organisational behaviour is ethical, where emphasis is not on compliance but on a set of core ethical values that allow individual and corporate expression. It is our strong belief that compliance cannot replace ethics.

Oil and ethnic inequality in Nigeria

Although it is known that ethnic biases exist in Africa, less is known about how these respond to natural resource prices. Many ethnically fragmented African countries depend on a small number commodities for their export base. Oil prices experienced in early life predict differential adult outcomes across Nigerian ethnic groups. Our difference-in-difference approach compares members of southern ethnicities to other Nigerians from the same birth cohort. This North-South distinction mirrors several economic, political, and religious cleavages in the country. Greater prices in a southern individual’s birth year predict several relative outcomes, including reduced fertility, delayed marriage, higher probabilities of working and having a skilled occupation, greater schooling, lower height, and greater BMI. These microeconomic impacts are explained by macroeconomic responses to oil prices; relatively, urban incomes increase, food production declines, and maternal labor intensifies in the South.     

Healthcare costs among men with favorable risk prostate cancer managed with observation strategies versus immediate treatment in an integrated healthcare system

Objective: This study explored short-term healthcare costs of men managed with observation strategies (OBS) vs immediate treatment (IMT) for favorable risk prostate cancer (PCa) from the Geisinger Health System, a single integrated health system in Pennsylvania, as evidence from the community setting is limited.

Methods: A retrospective cohort study was conducted using electronic health records from men aged ≥40 years diagnosed with favorable risk PCa (T1 or 2, PSA ≤15?ng/mL, Gleason ≤7 [3?+?4]) between January 2005 and October 2013. Prostate-specific healthcare costs were compared between the OBS and IMT cohorts in men with ≥3 years of follow-up and available linked claims data. Sub-group analyses focused on those men with low-risk PCa (T1-2a, PSA ≤10?ng/mL, Gleason ≤6). Sensitivity analysis stratified the study sample in three cohorts: OBS, switched from OBS to definitive treatment (OBS switch), and IMT.

Results: A total of 352 patients were included (OBS?=?70 and IMT?=?282). Compared with IMT, OBS resulted in significantly lower cumulative PCa-related healthcare costs for the first 3 years ($15,785 vs $23,177; p-value <.001). The main cost drivers were outpatient procedures. The OBS cohort had the lowest incremental PCa-related healthcare costs in the first 3 years (OBS: $5,011 vs OBS switch: $26,040, net cost savings?=?$21,029, p?p?Conclusions: In favorable risk PCa, half of the patients who initially chose OBS eventually underwent treatment after their PCa diagnosis. As expected, OBS was associated with reduced disease management costs compared with IMT.     

Pension Reform,Factor Mobility and Trade with Country-Specific Goods

This paper studies the effects of pension reform in a two-country model with country-specific goods. It shows that in the case of dynamic efficiency, a switch from a pay-as-you-go to a more-funded pension scheme leads to an inflow of labour to the reforming country. Reallocation of capital depends on the degree of substitutability between goods produced in the countries. If the goods produced in the countries are substitutes (complements), capital stock grows (declines) in the reformed country relative to the neighbouring country. Social security reform makes goods produced in the reformed country cheaper; this has an additional negative effect on the old generation in the reformed country, but compensates the old generation in the neighbouring country with cheaper imports due to a reduction in the tax base arising from emigration.     

Unintended Consequences of Changing Accounting Standards: The Case of Fair Value Accounting and Mandatory Dividends

A growing body of literature investigates the interaction of changes in accounting standards with institutions such as investor protection laws and corporate governance mechanisms. We examine the unintended consequences of fair value accounting in determining mandated preferred dividends. We study the case of Russian energy conglomerate UES, which had a good corporate governance track record and a consistent dividend history. Following its adoption of fair value accounting, UES reported the highest quarterly profit in world corporate history, but it subsequently omitted dividends for all its shareholders. The case analysis suggests that the transitory nature of fair value adjustments and the interaction with the investment policy were important considerations in justifying the dividend omission. The reduction in preferred dividends was not offset by any capital gains, and led to a wealth transfer from preferred to ordinary shareholders. Thus, requiring the use of fair value accounting when determining the dividend distribution base can lead to unintended consequences and increase agency costs for minority shareholders.     

The effects of corporate governance and audit and non-audit fees on IPO Value

This paper examines the effects of non-executive board members, audit committee composition and financial expertise, and fees paid to audit firms on the value of 375 UK initial public offerings (IPOs). Empirical findings show that underpricing decreases in audit fees whereas it increases in non-audit fees. A higher proportion of non-executive directors on the firm’s board and audit committees with a higher proportion of non-executive directors and financial accounting expertise of their members positively moderate the inter-relationships between underpricing and both audit and non-audit fees paid by companies going through an IPO. Further investigations using the adjusted price-to-book value as a proxy for firm value at IPO confirm our main findings that internal governance mechanisms may complement services provided by the auditors in terms of generating higher valuations. Controlling for the simultaneous determination of audit and non-audit fees, our results remain consistent.
