Residual Income versus Discounted Cash Flow Valuation Models: An Empirical Study

Valuation plays a central role in the financing, investing and operating decisions of companies and many methods are employed to approximate the true value of a company. Although these techniques are based on similar theory, they may generate different results in application. This study incorporates an empirical approach to compare the outcomes of two different methods: residual income and discounted cash flow valuation models. The aim of this study is to test whether these methods result in different values and to contribute to the understanding of why these two valuation techniques, although similar in theory, may generate different results when applied to real life companies. There are a number of studies that compare these two methods theoretically. Some studies claim the superiority of one method over the other and some argue that these two methods should yield the same results when applied properly. In this study, the residual income and discounted cash flow models are applied to nine Turkish companies and the results are compared. We have obtained the data for the study with site visits to the companies and with the help of the managements of the companies.
Western high-performance HR practices in China: a comparison among public-owned, private and foreign-invested enterprises

The current study is a comparison of the status of high-performance human resource (HR) practices and organizational goal priorities (economic and humanistic) in Chinese domestic-owned (public-owned and private-owned) and foreign-invested enterprises. This study also investigates the relationship between organization goal priorities and the adoption of high-performance HR practices. The study sample included 167 different organizations in China. The results indicate that, as predicted, humanistic goals were emphasized most in foreign-owned enterprises, least in Chinese public-owned enterprises and the emphasis in privately owned enterprises fell in between the other two types of enterprises. However, the three types of organizations did not differ from each other on most of the high-performance HR practices, except in their levels of recruitment autonomy. We also found that the link between organizational goals and HR practices was the strongest for private-owned enterprises, followed by foreign-invested enterprises, and then public-owned enterprises. The implications of these results are discussed.
Organizational Citizenship Behavior, Version 2.0: A review and Qualitative Investigation of OCBs for Knowledge Workers at Google and beyond

Organizational citizenship behaviors are discretionary employee behaviors that are helpful but not absolutely required by employers. While a great deal of information has been gleaned about the importance of organizational citizenship behaviors in the workplace, the nature of work has fundamentally changed; with this shift, the nature of organizational citizenship behavior for modern workers is also likely to have changed. Thus, the field is ready for an evolution in how we conceptualize organizational citizenship behavior that considers the contemporary nature of work. We carried out a multistage qualitative study designed to provide an understanding of a new generation of organizational citizenship behaviors as expressed at Google, a high-innovation, fast-paced firm, characteristic of the new form of work common to the high-technology industry and knowledge economy. Our findings indicate that some established organizational citizenship behavior concepts map onto knowledge workers' conceptualizations of .
CONCENTRATION-PROFITS MONOPOLY VS. EFFICIENCY DEBATE: SOUTH AFRICAN EVIDENCE

Using the new official measures of concentration, this study finds a strong and highly significant correlation between concentration and industry profitability for South African manufacturing industries. This correlation is consistent with both the monopoly hypothesis of the traditional structure-conduct-performance paradigm and Demsetz's efficiency hypothesis that concentration of industry reflects the dominance of superior low-cost firms.

Shorter intervals at peak SV vs.V̇O2max may yield high SV with less physiological stress

Abstract The purpose of this study was to evaluate whether greater and sustainable stroke volume (SV) responses may be obtained by exercise intensities corresponding to peak SV (SVpeak) vs. maximal O2 consumption (), and short vs. long intervals (SI vs. LI). Nine moderate- to well-trained male athletes competing at regional level specialists of cyclist, track and field volunteered to take part in the study (: 59.7 ± 7.4 mL·min−1·kg−1). Following familiarisation sessions, was determined, and then SVpeak was evaluated using exercise intensities at 40%–100% of by nitrous-oxide rebreathing (N2ORB) method. Then each separate participant exercised wattages corresponding to individual and SVpeak during both SI (SI and SISVpeak) and LI (LI and LISVpeak) workouts on a cycle ergometer. Main results showed that both SI and SISVpeak yielded greater SV responses than LI and LISVpeak (p ≤ 0.05). Mean SV responses were greater in LISVpeak than in LI (p ≤ 0.05), but there was no statistical difference between SISVpeak and SI. However, there was significantly less physiological stress based on VO2, respiratory exchange ratio, heart rate and rate of perceived exhaustion in SVpeak than in intensities (p ≤ 0.05). Moreover, SV responses at exercise phases increased in the early stages and remain stable until the end of SI and SISVpeak workouts (p > 0.05), while they were gradually decreasing in LI and LISVpeak sessions (p ≤ 0.05). In conclusion, if the aim of a training session is to improve SVpeak with less physiological stress, SISVpeak seems a better alternative than other modalities tested in the present study.
Inflation and Costs of Price Adjustment

How MUCH? Companies that sell through catalogs run into a pricing problem. Fast rising prices threaten to make catalog quotes out of date. Montgomery Ward & Co. which bought cautiously for its winter catalog, says it is " keeping its fingers crossed " that prices won't surge much in the near future. An official of Oak Supply & Furniture Co., Chicago, complains that the company's catalogs have been obsolete in terms of prices before they got into customers' hands the past two years. Basco Inc., Cherry Hill, N.J. mailed its latest catalog just a few weeks ago but already is reviewing some prices. J. C. Penney Co. says it stands behind prices during the approximately sevenmonth life of its semiannual catalogs. Like other companies, it gets guarantees from many vendors that they won't raise their prices for specified periods. But more catalog sellers tell customers prices are subject to change. Jewelcor Inc. puts such a warning on its catalog's jewelry pages. Some companies, such as Basco, consider putting out catalogs more frequently to keep up with prices. For the last two years Sears Roebuck has issued some 20 special catalogs twice rather than once a year. (Wall Street Journal-10/31/74).
Mammalian transcription factor LSF is a target of ERK signaling

LSF is a mammalian transcription factor that is rapidly and quantitatively phosphorylated upon growth induction of resting, peripheral human T cells, as assayed by a reduction in its electrophoretic mobility. The DNA‐binding activity of LSF in primary T cells is greatly increased after this phosphorylation event (Volker et al. [ 1997 ]: Genes Dev 11:1435–1446). We demonstrate here that LSF is also rapidly and quantitatively phosphorylated upon growth induction in NIH 3T3 cells, although its DNA‐binding activity is not significantly altered. Three lines of experimentation established that ERK is responsible for phosphorylating LSF upon growth induction in both cell types. First, phosphorylation of LSF by ERK is sufficient to cause the reduced electrophoretic mobility of LSF. Second, the amount of ERK activity correlates with the extent of LSF phosphorylation in both primary human T cells and NIH 3T3 cells. Finally, specific inhibitors of the Ras/Raf/MEK/ERK pathway inhibit LSF modification in vivo. This phosphorylation by ERK is not sufficient for activation of LSF DNA–binding activity, as evidenced both in vitro and in mouse fibroblasts. Nonetheless, activation of ERK is a prerequisite for the substantial increase in LSF DNA–binding activity upon activation of resting T cells, indicating that ERK phosphorylation is necessary but not sufficient for activation of LSF in this cell type.

Impact of persistent substance misuse on 1-year outcome in first-episode psychosis.

BACKGROUND Substance misuse is a common comorbid problem in people presenting with first-episode psychosis and is associated with a poor short-term outcome. AIMS The aim of this study is to examine differences in baseline characteristics and 1-year outcome between individuals with first-episode psychosis who have never misused substances, those who stop misusing substances after initial presentation and those who persistently misuse substances over the 1-year assessment period. METHOD Patients were recruited to the Northern Ireland First Episode Psychosis Study (n = 272). Clinical assessments were performed at baseline and at 1 year (n = 194) and data were collected from the case notes. RESULTS Individuals with persistent substance misuse had more severe depression, more positive symptoms, poorer functional outcome and greater rates of relapse at 1 year than those who stopped and those who had never misused substances. There were no differences in outcome between people who had never misused substances and those who stopped misusing after presentation. CONCLUSIONS These results support assertive intervention targeted at comorbid substance misuse in individuals with first-episode psychosis.
Credit Cycles - (Now published in 'Journal of Political Economy', vol.105(2), April 1997, pp.211-248.)

This paper is a theoretical study into how credit constraints intereact with aggregate economic activity over the business cycle. We construct a model of a dynamic economy in which lenders cannot force borrowers to repay their debts unless the debts are secured. In such an economy, durable assets such as land, buildings and machinery play a dual role: they are not only factors of production, but they also serve as collateral for loans. Borrowers' credit limits are affected by the prices of the collateralized assets. And at the same time, these prices are affected by the size of the credit limits. The dynamic interaction between credit limits and asset prices turns out to be a powerful transmission mechanism by which the effects of shocks persist, amplify, and spill over to other sectors. We show that small, temporary shocks to technology or income distribution can generate large, persistent fluctuations in output and asset prices.
Measuring and mitigating oauth access token abuse by collusion networks

We uncover a thriving ecosystem of large-scale reputation manipulation services on Facebook that leverage the principle of collusion. Collusion networks collect OAuth access tokens from colluding members and abuse them to provide fake likes or comments to their members. We carry out a comprehensive measurement study to understand how these collusion networks exploit popular third-party Facebook applications with weak security settings to retrieve OAuth access tokens. We infiltrate popular collusion networks using honeypots and identify more than one million colluding Facebook accounts by "milking" these collusion networks. We disclose our findings to Facebook and collaborate with them to implement a series of countermeasures that mitigate OAuth access token abuse without sacrificing application platform usability for third-party developers. These countermeasures remained in place until April 2017, after which Facebook implemented a set of unrelated changes in its infrastructure to counter collusion networks. We are the first to report and effectively mitigate large-scale OAuth access token abuse in the wild.
New Service Development Process

Abstract To continue to grow, more and more U.S. service firms have looked overseas in recent years to find markets for their offerings. Thus, innovation in the global context has become a strategic imperative for many service firms. While the issue of how to foster service innovation has been an area of extensive research, the cross-national comparison of innovation practices particularly between developed and emerging countries has been only a nascent field of research. To address this gap in the literature we conducted a comparative study of new service development process and stages of the financial service firms in an emerging country, India, and a developed country, the United States. The results support the central argument of the article that significant cross-national differences do exist with regard to a firm's new service development process. The findings should be of value to managers faced with the tasks of selecting and managing service innovation in emerging markets, as well as those firms experiencing international competition.
Survival of Neisseria meningitidis outside of the host: environmental effects and differences among strains

SUMMARY Neisseria meningitidis is a gram-negative bacterium that lives as a commensal in the human nasopharynx. Meningococci are generally non-invasive, but can invade the nasopharyngeal epithelia and enter the bloodstream causing life-threatening illnesses. It is generally thought that meningococci do not survive for long outside the host, and that transmission requires relatively close contact between hosts. There are some reports, however, that meningococci can survive drying on surfaces, including glass, plastic and cloth. Our examination of N. meningitidis strains dried on glass showed differences in survival of isolates belonging to serogroups B, C and W135, including persistence of Cuban, New Zealand, and Norwegian epidemic strains up to 8 days, depending on temperature and humidity. Survival of a New Zealand epidemic strain isolate NZ98/254 under ambient conditions in the laboratory was greatest in winter suggesting that environmental factors impacted survival. For most isolates, including NZ98/254, survival under controlled conditions at 30 °C was greater at 22% than 30% relative humidity. There were also some differences in survival between carriage and invasive strains. The results suggest that N. meningitidis could be transmitted through contact with surfaces outside the host, potentially including contact through shared drinking vessels.
TRF2 and the evolution of the bilateria

Kadonaga and colleagues present novel molecular insights into TATA-box-binding protein (TBP) family members and the evolution of complex animal body plans. They demonstrate that the TBP-related factor 2 (TRF2), which activates TATA-less core promoters, first arose in a common ancestor to the bilaterians and hypothesize that this new TRF2-based transcription system facilitated the evolution of bilateria.
Sequential microdissection and scanning electron microscopy of ciliary microvascular castings.

: Intracarotid injection of methylmethacrylate followed by tissue corrosion produces detailed replicas of the ocular microvasculature that can then be studied with the scanning electron microscope. The resultant photographs allow careful scrutiny of even the finest capillaries. However, when applied to the ciliary body, a complicated three dimensional system, we found stereo scanning electron micrography essential to fully appreciate its arteriolar and capillary interconnections. These stereoscopic analyses indicated that specific superficial vessels required excision to visualize deeper, previously hidden microvascular relationships. Using a pneumatically powered ultra microscissors guided by a micromanipulator we successfully removed these vessels. Deeper views were then obtained through repeat stereo scanning electron microscopy. This sequential microdissection and stereo scanning electron microscopy revealed that the major ciliary processes are supplied by two types of arterioles arising from the major arterial circle. Constricted anterior arterioles supply anterior and marginal aspects of the processes as well as interprocess capillary beds. Less constricted posterior arterioles feed capillaries confined to the base of the major processes as well as minor ciliary processes via posterior interprocess connections. Choroidal veins were seen to directly drain both anterior and posterior interprocess capillary beds.
ANTISOCIAL BEHAVIORAL SYNDROMES AND RETURN TO DRUG USE FOLLOWING RESIDENTIAL RELAPSE PREVENTION/HEALTH EDUCATION TREATMENT

This study compared residential addiction treatment clients meeting full DSM-III-R criteria for antisocial personality disorder (ASPD) with those reporting syndromal levels of antisocial behavior only in adulthood (AABS) on time to and severity of first posttreatment drug use. Antisocial syndrome and selected other mental disorders were assessed using the Diagnostic Interview Schedule, Revised for DSM-III-R, and validity of self-reported posttreatment drug behavior was measured against results of hair analysis. Among subjects followed within 180 days after treatment exit, individuals with ASPD were at modestly increased risk of a first lapse episode compared to those with AABS. However, the two groups did not differ in severity of lapse. Participants with ASPD demonstrated poorer agreement between self-reported posttreatment drug behavior and hair data. These results add to the evidence suggesting that the DSM requirement for childhood onset in ASPD may be clinically important among substance abusers in identifying a severely antisocial and chronically addicted group at elevated risk for early posttreatment recidivism. Our findings support the importance of careful classification of antisocial syndromes among substance abusers and the identification of characteristics of these syndromes that underlie clients’ risks for posttreatment return to drug use to provide optimally individualized treatment planning.
Maturation promoting factor destabilization mediates human chorionic gonadotropin induced meiotic resumption in rat oocytes

Human chorionic gonadotropin (hCG) mimics the action of luteinizing hormone (LH) and triggers meiotic maturation and ovulation in mammals. The mechanism by which hCG triggers meiotic resumption in mammalian oocytes remains poorly understood. We aimed to find out the impact of hCG surge on morphological changes, adenosine 3′,5′‐cyclic monophosphate (cAMP), guanosine 3′,5′‐cyclic monophosphate (cGMP), cell division cycle 25B (Cdc25B), Wee1, early mitotic inhibitor 2 (Emi2), anaphase‐promoting complex/cyclosome (APC/C), meiotic arrest deficient protein 2 (MAD2), phosphorylation status of cyclin‐dependent kinase 1 (Cdk1), its activity and cyclin B1 expression levels during meiotic resumption from diplotene as well as metaphase‐II (M‐II) arrest in cumulus oocyte complexes (COCs). Our data suggest that hCG surge increased cyclic nucleotides level in encircling granulosa cells but decreased their level in oocyte. The reduced intraoocyte cyclic nucleotides level is associated with the decrease of Cdc25B, Thr161 phosphorylated Cdk1 and Emi2 expression levels. On the other hand, hCG surge increased Wee1, Thr14/Tyr15 phosphorylated Cdk1, APC/C as well as MAD2 expression levels. The elevated APC/C activity reduced cyclin B1 level. The changes in phosphorylation status of Cdk1 and reduced cyclin B1 level might have resulted in maturation promoting factor (MPF) destabilization. The destabilized MPF finally triggered resumption of meiosis from diplotene as well as M‐II arrest in rat oocytes.
The use and determinants of credit derivatives in Italian banks

Purpose - – This paper aims to answer the following research questions: To what extent do banks use credit derivatives (CDs)? What are the differences between users and non-users? What are the main underlying motivations? Design/methodology/approach - – The annual reports of 112 Italian banks are analysed during the 2005-2011 period. By estimating a probit regression model, two incentives for using CD are tested: managing credit risk, and increasing a bank’s income composition/diversification. Different sub-samples are considered. The motivations are further investigated to understand whether they vary before and after the crisis. Findings - – A limited number of banks use CD and larger and listed banks are more likely to do so. The results do not support the hedging hypothesis. Signals pointing towards the financial distress hypothesis emerge. Less capitalised banks are more likely to use CD. For listed banks, the findings support the hypothesis that economies of scale exist. After the financial crisis, a number of determinants tend to gain significance, and a speculative driver emerges. Originality/value - – Previous studies focus primarily on the USA, and single-country studies do not exist in the literature. Given the importance of risk management that the crisis has reinforced, investigating whether CD use has changed before and after the crisis is of interest. Given the incompleteness of the information on CDs, the paper contributes to increasing the available information on CDs by hand-collecting data from banks’ financial statements.
Robust Photogeneration of H2 in Water Using Semiconductor Nanocrystals and a Nickel Catalyst

Robust Reduction A major challenge in the design of artificial photosynthesis catalysts has been their instability under the reaction conditions—a problem that plants and other autotrophs address by perpetually reproducing their biochemical machinery. Han et al. (p. 1321, published online 8 November) now demonstrate a system for photoreductive hydrogen generation in water that manifests undiminished activity for weeks at a time. Semiconductor nanoparticles for light absorption were combined with a soluble nickel complex for the catalytic chemistry. The system currently requires a sacrificial electron donor, but its robustness shows promise for future pairing with an integrated oxidation catalyst. A photoreduction system combining nanoparticulate light absorbers with a soluble molecular catalyst proves stable for weeks. Homogeneous systems for light-driven reduction of protons to H2 typically suffer from short lifetimes because of decomposition of the light-absorbing molecule. We report a robust and highly active system for solar hydrogen generation in water that uses CdSe nanocrystals capped with dihydrolipoic acid (DHLA) as the light absorber and a soluble Ni2+-DHLA catalyst for proton reduction with ascorbic acid as an electron donor at pH = 4.5, which gives >600,000 turnovers. Under appropriate conditions, the precious-metal–free system has undiminished activity for at least 360 hours under illumination at 520 nanometers and achieves quantum yields in water of over 36%.
Logic Macroprogramming for Wireless Sensor Networks

It is notoriously difficult and tedious to program wireless sensor networks (WSNs). To simplify WSN programming, we propose Sense2P, a logic macroprogramming system for abstracting, programming, and using WSNs as globally deductive databases. Unlike macroprograms in previous works, our logic macroprograms can be described declaratively and imperatively. In Sense2P, logic macroprogrammers can easily express a recursive program or query that is unsupported in existing database abstractions for WSNs. We have evaluated Sense2P analytically and experimentally. Our evaluation result indicates that Sense2P successfully realizes the logic macroprogramming concept while consuming minimal energy as well as maintaining completeness and soundness of the answers.
