ABSTRACT We derive in the present study a set of equations that yield, through regression analysis, estimates of the elasticity of substitution and of the indexes of technical change attributed to Hicks, Harrod and Solow. On the basis of data drawn from the U.S. non-farm economy, we obtain estimates that are consistent with other findings namely a value for the elasticity of substitution (between labour and capital) that is less than unity and indexes which imply that technology has tended to be Hicks labour-saving, Harrod capital-saving and Solow labour-saving.

We develop a framework to estimate the aggregate capital‐labor elasticity of substitution by aggregating the actions of individual plants. The aggregate elasticity reflects substitution within plants and reallocation across plants; the extent of heterogeneity in capital intensities determines their relative importance. We use micro data on the cross‐section of plants to build up to the aggregate elasticity at a point in time. Interpreting our econometric estimates through the lens of several different models, we find that the aggregate elasticity for the U.S. manufacturing sector is in the range of 0.5–0.7, and has declined slightly since 1970. We use our estimates to measure the bias of technical change and assess the decline in labor's share of income in the U.S. manufacturing sector. Mechanisms that rely on changes in the relative supply of factors, such as an acceleration of capital accumulation, cannot account for the decline.

The U.S

The U.S. was a pioneer in establishing the world's first modern intellectual property system. That system was distinguished by the provision of broad access to, and strict enforcement of, property rights in new inventions, coupled with the requirement of public disclosure, and it was effective at stimulating the growth of a market for technology and technical change more generally. Far from being static, fundamental modifications were introduced over time in response to changing circumstances. That such adjustments so often proved to be constructive owes partly to a private market being a central feature of the system, and partly to the democratic structure of U.S. institutions.

Bullying Behavior

The purpose of this research is to find out: (1) The correlation between self esteem and bullying behavior, (2) The correlation between conformity and bullying behavior, (3) The correlation between self esteem and conformity towards bullying behavior. The subjects of this research were 86 students on VIII grade of SMP Barunawati Surabaya, who are selected using population sampling technique. Data were collected using likert scales of self esteem, conformity, and bullying behavior. Data analysis technique of this research using multiple linier regression analysis. Results of this research are: (1) self esteem has a significant correlation towards bullying behavior with a negative correlation, can be seen from the significance value 0,000 and regression coefficientt -0,526, (2) conformity has a significance correlation towards bullying behavior with a positive  correlation that is shown from the significance value 0,003 and regression coefficientt 0,321, (3) Rsquare value 0,301 means that 30,1% variations on bullying behavior is influenced of self esteem and conformity, the other variable that has a value of 69,9% is caused of other variable that is not measured in this research. Abstrak: Penelitian ini bertujuan untuk menemukan: (1) Hubungan antara harga diri dengan perilaku bullying, (2) Hubungan antara konformitas dengan perilaku bullying, (3) Hubungan antara harga diri dan konformitas dengan perilaku bullying. Penelitian ini menggunakan metode kuantitatif korelasional. Subjek pada penelitian ini ialah 86 siswa kelas VIII SMP Barunawati Surabaya yang dipilih dengan menggunakan teknik sampel populasi. Data skala harga diri, skala konformitas dan skala perilaku bullying diperoleh menggunakan skala likert. Teknik analisis data dalam penelitian ini adalah uji analisis regresi linier berganda. Hasil penelitian menunjukan bahwa: (1) harga diri memiliki hubungan yang signifikan dengan perilaku bullying dengan arah hubungan yang negatif, dapat dilihat dari signifikansi sebesar 0,000 dan koefisien regresi -0,526. (2) konformitas memiliki hubungan yang signifiksn dengan perilaku bullying dengan arah hubungan  positif yang dapat dilihat dari signifikansi sebesar 0,003 dan koefisien regresi sebesar 0,321. (3) nilai Rsquare sebesar 0,301 artinya sebesar 30,1% variasi pada perilaku bullying dipengaruhi oleh harga diri dan konformitas, sisanya sebesar 69,9% disebabkan oleh variabel lain yang tidak diukur dalam penelitian ini.

The contracting process is fraught with difficulties. While successful completion of a contract is the goal, problems and challenges often arise. This requires skills in negotiation or mediation. Dealing with these problems, even if it means recommending contract termination, is part of the job of the contract representatives who oversee the specific projects. Data from the Contracting Officer Representatives survey conducted by the U.S. Merit Systems Protection Board (2005) is used. An index of perceived outcomes (deliverables or services were timely, of high quality, complete, contributed to the agency mission, fair and reasonable, and of good value) was constructed. Roughly, half the respondents indicated that they had had to deal with a problem or challenge. Problem-solving actions (discussions with contactors and other governmental officials, the submission of official documentations, and the recommendation of non-payment or termination sanctions) were submitted to a regression analysis (R2 = .19). From a dozen options, only discussion of the problem with contractors and with their own supervisors along with the recommendation of contract termination registered some meaningful importance (Standardized Betas .1 to .2).

We looked into the statistical association of prothrombin time (PT) and activated partial thromboplastin time (APTT) with disseminated intravascular coagulation (DIC) score calculated using the International society for thrombosis and haemostasis (ISTH) scoring system. The PT, APTT, PT + APTT, and PT/APTT ratios were evaluated against the DIC score by linear regression analysis in fifty inpatients with suspected DIC. The PT, PT + APTT, and PT/APTT ratios were all found to be statistically significant in predicting DIC scores with values of 0.02, 0.03, and 0.02, respectively. The APTT alone was not found to be statistically significant in predicting DIC score and had a value of 0.09. This scoring system does not need d-dimer levels and the platelet count.

A procedure of estimation of the non-regular component of a power consumption schedule is described in this paper. A value of the non-regular component enables to evaluate the minimal error of daily-ahead power consumption forecast based on regression mathematical models. Evaluating calculations are given by the example of 10 regional power systems of Russia.
