ANALISIS PENGARUH RETURN ON ASSETS (ROA), RETURN ON EQUITY (ROE) DAN NET PROFIT MARGIN (NPM) TERHADAP RETURN SAHAM PADA PERUSAHAAN MANUFAKTUR YANG TERDAFTAR DI BURSA EFEK INDONESIA

Title "The Analysis Return on assets (ROA), return on equity (ROE), net profit margin (NPM) of the return on the stock of manufacturing companies listed in Indonesia Stock Exchange." This research aims to influence the performance tester manufacturing company (ROA, ROE, and NPM) of the shares and return of these three variables (ROA, ROE, and NPM) where the most significant return to shareholders registered at the Indonesian Stock Exchange. In this research, data analysis technique that is used is to perform calculations find ROA, ROE, NPM, stock return from year 2005,2006,2007, perform statistical testing, test the assumption of classical regression analysis and berganda. Research results indicate that simultaneously calculated F = 0.609 less than the F table = 3.80 means ROA, ROE, and NPM does not affect the stock return. And that the partial calculating ROA T = 0.899 T is less than the table means = 1.77 ROA does not affect the stock return. ROE calculated T = -0.437 is less than the table T = 1.77 does not mean ROE barpangaruh return to shareholders. NPM calculated T = -1.123 is less than Q = 1.77 means that the table NPM does not affect the stock return. This condition indicates that the ROA, ROE and NPM has contributed to a low return on shar

On Coarse Spectral Geometry in Even Dimension

Let $\sigma$ be the involution of the Roe algebra \Roe{\RR} which is induced from the reflection \RR\to\RR; x\mapsto -x. A graded Fredholm module over a separable $C^*$-algebra $A$ gives rise to a homomorphism \tilde{\rho}:A\to\Roe{\RR}^\sigma to the fixed-point subalgebra. We use this observation to give an even-dimensional analogue of a result of Roe. Namely, we show that the $K$-theory of this symmetric Roe algebra is K_0(\Roe{\RR}^\sigma)\cong\ZZ, K_1(\Roe{\RR})=0, and that the induced map \tilde{\rho}_*:K_0(A) \to \ZZ on $K$-theory gives the index pairing of $K$-homology with $K$-theory

Habitat Selection and Risk of Predation: Re-colonization by Lynx had Limited Impact on Habitat Selection by Roe Deer

Risk of predation is an evolutionary force that affects behaviors of virtually all animals. In this study, we examined how habitat selection by roe deer was affected by risk of predation by Eurasian lynx - the main predator of roe deer in Scandinavia. Specifically, we compared how habitat selection by roe deer varied (1) before and after lynx re-established in the study area and (2) in relation to habitat-specific risk of predation by lynx. All analyses were conducted at the spatial and temporal scales of home ranges and seasons. We did not find any evidence that roe deer avoided habitats in which the risk of predation by lynx was greatest and information-theoretic model selection showed that re-colonization by lynx had limited impact on habitat selection by roe deer despite lynx predation causing 65% of known mortalities after lynx re-colonized the area. Instead we found that habitat selection decreased when habitat availability increased for 2 of 5 habitat types (a pattern referred to as functional response in habitat selection). Limited impact of re-colonization by lynx on habitat selection by roe deer in this study differs from elk in North America altering both daily and seasonal patterns in habitat selection at the spatial scales of habitat patches and home ranges when wolves were reintroduced to Yellowstone National Park. Our study thus provides further evidence of the complexity by which animals respond to risk of predation and suggest that it may vary between ecosystems and predator-prey constellations

Financial crisis and the effect of corporate governance practices on banks’ financial performance

This paper aims to identify whether the selected corporate governance practices of Malaysian Banks, affect either positively or negatively, its rate of return on equity (ROE).Descriptive research design has been used for this research to describe the characteristic of the banks’ compliance to corporate governance and the impact on its ROE. Data from all ten listed local banks in Malaysia were obtained to measure against four independent variables, ie. the proportion of non-executive directors, the proportion of institutional investors, the level of gearing and the concentration of ownership. It was found that the higher the level of gearing of the bank, the higher is the monitoring role of the lenders and the better would be the bank’s ROE. Future research can also compare pre and post-financial crisis corporate governance practices and its impact on Banks’ financial performances

DETERMINANT OF PROFITABILITY AND ITS IMPACT ON FIRM VALUE: EVIDENCE FROM INDONESIA STOCK EXCHANGE

Firm value is experiencing a downward trend is a problem that must be resolved. It is not firm’s main objective of maximizing shareholder wealth. This study aimed to analyze the effect of the debt to equity (DER), sales growth (SG), current ratio (CR), and total asset turnover (TATO) to the price to book value (PBV) with return on equity (ROE) as a variable intervening. Population in this research using manufacturing companies in Indonesia Stock Exchange in the period 2010-2015. Sampling technique used is purposive sampling with 34 companies selected according to predetermined criteria. The analysis technique used is the analysis using SPSS program, which previous research data has passed the test classic assumptions. The first regression model showed that the DER has a negative effect on ROE and significantly affect ROE. Sales Growth and TATO has a significant and positive effect on ROE. Meanwhile, CR does not have an impact on ROE. The second model shows that ROE has a significant and positive effect on the level of 5% on PBV.CR significant and positive effect on the level of 10% on PBV. Meanwhile, SG, TATO, and DER does not have effect on PBV, the study also showed that the ROE mediating influence between SG and TATO on PBV
