Learning by hiring and change to organizational knowledge: Countering obsolescence as organizations age

Research summary: This paper investigates the relationship between hiring and the ability of organizations to evolve their capabilities as they age. While prior research establishes that organizations become rigid to change as they age, it underemphasizes measures that they may take to renew their adaptive potential. I address this gap by investigating whether hiring stimulates change to the knowledge organizations possess. Learning by hiring, I argue, helps organizations to evolve their knowledge as they age by disrupting routine, introducing distant knowledge, and facilitating socialization. I test the effectiveness of these mechanisms using 38 years (1970–2007) of data from the U.S. biotechnology industry, and find that hiring stimulates more change as organizations age, enabling them to renew their knowledge and counter the effects of obsolescence. Managerial summary: As organizations age, they become less responsive to the needs of their environment, resulting in a trend for them to become technologically obsolete. Little is known as to how they may reverse this trend and counter obsolescence. I provide evidence that hiring may be used to stimulate change to organizational knowledge and capabilities as they age by disrupting routine activity, introducing new-to-the-firm knowledge, and inducing incumbent members to learn.

Retail financial services: transaction to relationship marketing

Presents the findings of a survey carried out among the financial directors of leading retail companies in Australia, Ireland, New Zealand and the UK. The purpose of the survey was to determine those factors that influence the development of financial services within retail organisations. Considers the introduction of financial services, within the context of retailers’ relationships with their customers, and retailers’ ability to build closer relationships with existing and potential customers. Financial service provision is, therefore, considered in the context of the relationship marketing paradigm. Considers the opportunities which financial services provide for retailers to move from a transactional to relationship approach to marketing.
The influence of accentuation and polysyllabicity on compensatory shortening in German

The aim of this study was to investigate the relationship between compensatory shortening and coarticulation in German tense and lax vowels in trochees and iambs and to determine whether this relationship was influenced by prosodic accentuation. Speakers produced near minimal pairs differing in vowel tensity in monosyllabic and disyllabic words (both trochees and iambs) in accented and deaccented contexts. We found significant effects of polysyllabic shortening, but only in tense vowels of nuclear-accented target words. Both stress patterns (trochaic and iambic) showed equal effects of polysyllabic shortening. Thus, while the duration of tense vowels in this study depended on accentuation and syllabicity, perhaps in order to provide perceptual cues for the listener, lax vowels were immune from lengthening and shortening phenomena. As a result, the durational difference between tense and lax vowels appears to lessen in prosodically weak contexts. The greater overlap of acoustic duration in deaccented contexts may contribute to the origin of the diachronic merger of tense and lax vowels in some languages.
An Efficient Microwave-Assisted Suzuki Reaction using a New Pyridine-Pyrazole/Pd(II) Species as Catalyst in Aqueous Media

A new pyridine-pyrazole N–N ligand has been conveniently synthesized and characterized by 1H-, 13C-NMR, IR spectroscopies, HRMS and X-ray single-crystal crystallography analyses. The ligand adds to palladium(II) under basic conditions to give high yields of an air-stable and water-soluble complex that was fully characterized by NMR and HRMS. The complex was investigated as a catalyst for the Suzuki reaction in aqueous media under microwave irradiation. The compound proved to be an effective catalyst.
Corporate Social Responsibility Incentivization Using Prospect Theory: 'Does Gender Play a Role?'

This study explores the role gender plays in incentivising executives to practice Corporate Social Responsibility (CSR) across various categories. If shareholders’ preferences toward CSR can be modeled using Prospect Theory, this study suggests that, incentives aimed at increasing total CSR should be pursued by separating CSR ‘strengths’ and ‘concerns’. This paper finds that differences exist between male and female executives in how they are incentivised to practice CSR.
Exploitation of Pseudomonas sp. for disease control and productivity in tea

A study was undertaken on exploitation of indigenous Pseudomonas strains isolated from tea rhizosphere for disease control and productivity in tea. This included in vitro studies on plant growth promotion and biocontrol properties like production of phytohormones, siderophore, hydrogen cyanide, phosphate solubilization, and resistance to agrochemicals. The ability of Pseudomonas sp, was determined by production of antimicrobial substances. Moreover, Pseudomonas sp, expressed synergistic activity with other beneficial bioinoculants which shows the way to make consortium. Pseudomonas sp. improved the soil nutrient status when applied integrately with 50% reduction of rock phosphate to provide higher yield of tea. The proposed study would provide the information on exploiting the Pseudomonas sp, as an ecofriendly and sustainable alternative to the existing chemicals for growth promotion and management of tea diseases.
Organizational Climate as a moderator of the Relationship between Transformational Leadership and Creativity

The interest is growing in the influence of transformational leadership on creativity at the organizational level. Transformational leaders increase the performance expectations and creativity levels of their followers. Recent studies showed that leaders' behaviors have important effects on creativity level of the employees. Creativity is consisted of three levels as individual, group and organizational creativity. Transformational leaders have effects on the creativity of the subordinates. Moreover, organizational climate can be important variable for the individual creativity in organizations. In this study, we assumed that the relationship between transformational leadership and followers' creativity moderated by organizational climate. The main purpose of this study is to examine the moderating role of organizational climate on the effect of transformational leadership on creativity. The survey is conducted on 178 employees in Istanbul, Turkey. As a result, there are significant moderating effects of cohesion climate dimension on the relationship between transformational leadership and followers' creativity. In addition pressure factor of the organizational climate has a significant negative moderating effect on this relationship.
A citizen centric framework for business developmnet in the public sector

This paper presents a citizen centric framework for how to conduct business development in the public sector. Our starting point is a case study in which we followed a large strategically important development project in a Swedish municipality. The project has transformed the municipality to large one-stop shop, with a Citizen Service Unit that acts as an important hub in the relationship between citizens and the offices of the municipality. As a result vast amounts of new data about citizens' interactions with the municipality have been generated. An unexpected side effect of the development project is that the framework under which business development takes place has become larger than before and must take data from more sources into account. This raises issues such as ownership of business development, handling of vast amount of data and whether the whole endeavour has made the municipality more effective or not.
CEO Overconfidence and the Impact on M&A Activity

What drives mergers and acquisitions decisions? Can an overconfidence bias affect decisions within the management team? This study complements recent work developed within the behavioral finance analyses of Mergers & Acquisitions and proposes the use of new variable to measure overconfidence. Using a sample of 8,895 takeover transactions completed by 993 CEOs in the United States – between 1992 and 2008 – it can be noticed that overconfident CEOs have 22% higher odds of engaging in corporate takeovers than rational CEOs.
Hepatitis C virus infection in spouses: sexual transmission or common exposure to the same risk factors?

OBJECTIVES:The aim of this study was to evaluate whether the transmission of hepatitis C virus (HCV) between spouses occurs through sexual contact or through other types of exposure.METHODS:We consecutively enrolled 311 chronic HCV carriers and their spouses. The spouses underwent HCV blood testing. Exposure to parenteral risk factors was compared between couples of which both partners were HCV positive and couples with one positive partner. In couples with both partners positive, qualitative detection of serum HCV RNA and genotyping were performed.RESULTS:The prevalence among spouses was 10.3% (32/311). The mean age was higher for HCV-positive spouses (57.7 vs 49.6 yr for HCV-negative spouses; p < 0.01). The prevalence among spouses increased with the duration of marriage, whereas no difference was found in relation to the clinical status of the index case. The 32 HCV-positive spouses reported parenteral exposure (blood transfusion, drug use, and use of multiple-use glass syringes inside or outside the family) more often than the 279 HCV-negative spouses (84.4% vs 26.2%; odds ratio [OR], adjusted for age by multiple logistic regression analysis, 12.4; 95% CI = 4.5–34.0). The percentage of couples sharing glass syringes was significantly higher among those with both partners infected (65.6% vs 12.9%; OR = 12.9; 95% CI = 5.4–31.4). Qualitative serum HCV RNA was determined in 22 couples with both partners infected; in 13 of them, both partners were HCV RNA positive, whereas in the remaining nine, only one partner was positive. In eight of the 13 couples with both partners HCV RNA positive, the same genotype was found for both partners.CONCLUSIONS:The findings that the same genotype was detected for both partners in relatively few couples, and that a history of parenteral exposure was an independent predictor of HCV positivity, suggest that the risk of sexual transmission is low. The sharing of glass syringes may have played an important role in transmission between spouses.
Reclassification of Bacteriovorax marinus as Halobacteriovorax marinus gen. nov., comb. nov. and Bacteriovorax litoralis as Halobacteriovorax litoralis comb. nov.; description of Halobacteriovoraceae fam. nov. in the class Deltaproteobacteria.

The taxonomic status of saltwater Bdellovibrio-like prokaryotic predators has been revised to assign species to Halobacteriovorax gen. nov. A reclassification of Bacteriovorax marinus as Halobacteriovorax marinus comb. nov. (type strain ATCC BAA-682(T) = DSM 15412(T)) and Bacteriovorax litoralis as Halobacteriovorax litoralis comb. nov. (type strain ATCC BAA-684(T) = DSM 15409(T)) is proposed. This revision is necessary because a previous proposal to retain saltwater isolates as species of Bacteriovorax and reclassify Bacteriovorax stolpii as Bacteriolyticum stolpii was not approved. The type species of a genus cannot be reassigned to another genus. Bacteriovorax stolpii is thus retained as the type species of Bacteriovorax and Halobacteriovorax marinus is the type species of Halobacteriovorax and of Halobacteriovoraceae fam. nov.
Corporate Governance Structure and Its Impact on Human Resource Management and Financial Performance

In this paper, the authors discuss the impact of corporate governance structure on human resource management and financial performance in the context of Colombian business environment. For this purpose, the paper will analyze the concept of corporative governance and discuss the streams of thought that study both the structure of corporate governance as the behavior of managers, the agency theory and stewardship theory. The methodological development aims to test four models by using regression analysis. The results allow to identify that the structure of corporate governance and distinctive capabilities of human resource are positively related to company performance, but this does not explain the attitude steward of the CEO and collaboration systems.
A Model Based on Support Vector Machine for Early Warning Financial Crisis

Financial indicators and corporate governance variables were sieved separately to get representative variables via factor analysis,mean value test and correlation analysis.Then,an empirical analysis was done by support vector machine(SVM). The results showed that the SVM model is superior in predicting the financial bankruptcy risk to other methods.Comparing the SVM model with the model based on financial indicators,it is found that the model introducing corporate governance variables in it is more predictable,where the variables include the proportions of circulating shares,shares held by the biggest shareholders and share ownership concentration.This method is worthy of practical applications to a certain extent.
Quantifying cardio-respiratory phase synchronization—a comparison of five methods using ECGs of post-infarction patients

Objective: Phase synchronization between two weakly coupled oscillators occurs in many natural systems. Since it is difficult to unambiguously detect such synchronization in experimental data, several methods have been proposed for this purpose. Five popular approaches are systematically optimized and compared here. Approach: We study and apply the automated synchrogram method, the reduced synchrogram method, two variants of a gradient method, and the Fourier mode method, analyzing 24h data records from 1455 post-infarction patients, the same data with artificial inaccuracies, and corresponding surrogate data generated by Fourier phase randomization. Main results: We find that the automated synchrogram method is the most robust of all studied approaches when applied to records with missing data or artifacts, whereas the gradient methods should be preferred for noisy data and low-accuracy R-peak positions. We also show that a strong circadian rhythm occurs with much more frequent phase synchronization episodes observed during night time than during day time by all five methods. Significance: In specific applications, the identified characteristic differences as well as strengths and weaknesses of each method in detecting episodes of cardio-respiratory phase synchronization will be useful for selecting an appropriate method with respect to the type of systematic and dynamical noise in the data.
Aggregate Queries in Wireless Sensor Networks

Recently as efficient processing of aggregate queries for fetching desired data from sensors has been recognized as a crucial part, in-network aggregate query processing techniques are studied intensively in wireless sensor networks. Existing representative in-network aggregate query processing techniques propose routing algorithms and data structures for processing aggregate queries. However, these aggregate query processing techniques have problems such as high energy consumption in sensor nodes, low accuracy of query processing results, and long query processing time. In order to solve these problems and to enhance the efficiency of aggregate query processing in wireless sensor networks, this paper proposes Bucket-based Parallel Aggregation (BPA). BPA divides a query region into several cells according to the distribution of sensor nodes and builds a quadtree, and then processes aggregate queries in parallel for each cell region according to routing. It sends data in duplicate by removing redundant data, which, in turn, enhances the accuracy of query processing results. Also, BPA uses a bucket-based data structure in aggregate query processing, and divides and conquers the bucket data structure adaptively according to the number of data in the bucket. In addition, BPA compresses data in order to reduce the size of data in the bucket and performs data transmission filtering when each sensor node sends data. Finally, in this paper, we prove its superiority through various experiments using sensor data.
Electric Load Forecasting using SVMS

Support vector machines (SVMs) have been proposed as a novel technique and applied to regression recently. In this paper, SVMS are used for load forecasting. The training sample sets are chosen and preprocessed before every forecasting. Then the interference of the non-correlative and bad samples for the forecasting can be avoided. The effectiveness and the feasibility of forecasting of the employed method are examined through some simulations
Inertial delay control based sliding mode control for active suspension with full car model

This paper deals with reducing the vertical oscillations of the vehicle using active suspension. A full car model is considered with pitch and roll motion dynamics. Sliding mode control is used to control the nominal system matrices while the effect of disturbances from the road profile is suppressed through an inertial delay control (IDC) estimation technique. Global asymptotic stability of the controller is proved using Lyapunov criterion. Simulations are carried out in MATLAB/Simulink to evaluate the performance of the controller under parametric uncertainties and external road disturbance.
Hemodynamic actions of insulin.

There is accumulating evidence that insulin has a physiological role to vasodilate skeletal muscle vasculature in humans. This effect occurs in a dose-dependent fashion within a half-maximal response of approximately 40 microU/ml. This vasodilating action is impaired in states of insulin resistance such as obesity, non-insulin-dependent diabetes, and elevated blood pressure. The precise physiological role of insulin-mediated vasodilation is not known. Data indicate that the degree of skeletal muscle perfusion can be an important determinant of insulin-mediated glucose uptake. Therefore, it is possible that insulin-mediated vasodilation is an integral aspect of insulin's overall action to stimulate glucose uptake; thus defective vasodilation could potentially contribute to insulin resistance. In addition, insulin-mediated vasodilation may play a role in the regulation of vascular tone. Data are provided to indicate that the pressor response to systemic norepinephrine infusions is increased in obese insulin-resistant subjects. Moreover, the normal effect of insulin to shift the norepinephrine pressor dose-response curve to the right is impaired in these patients. Therefore, impaired insulin-mediated vasodilation could further contribute to the increased prevalence of hypertension observed in states of insulin resistance. Finally, data are presented to indicate that, via a yet unknown interaction with the endothelium, insulin is able to increase nitric oxide synthesis and release and through this mechanism vasodilate. It is interesting to speculate that states of insulin resistance might also be associated with a defect in insulin's action to modulate the nitric oxide system. (ABSTRACT TRUNCATED AT 250 WORDS)

Analysis of Battery Lifetime Extension in a Small-Scale Wind-Energy System Using Supercapacitors

Due to the variable characteristics of renewable generation, batteries used in renewable-power systems can undergo many irregular, partial charge/discharge cycles. In turn, this can also have a detrimental effect on battery lifetime and can increase project costs. This study presents a method of improving battery lifetime in a small-scale remote-area wind-power system by the use of a battery/supercapacitor hybrid energy storage system. The supervisory control algorithm and hardware implementation are described and projected long-term benefits of the proposed system are assessed by simulation. A representative dynamic model of the overall system, incorporating realistic wind-speed and load-power variations has been developed. An analysis is presented of the potential improvement in battery lifetime that is achievable by diverting short-term charge/discharge cycles to a supercapacitor energy-storage system. This study introduces a method by which supercapacitor energy storage systems and control algorithms can be evaluated and implemented in the application area considered. The composition of a prototype test system is described and experimental results are presented to demonstrate system feasibility.
Managerial Incentives and Investment in R&D in Large Multiproduct Firms

Incentives for division managers in large firms affect their risk orientation and thus their decisions to invest in R&D. This paper reviews theory and hypothesizes that division managers' incentive compensation that is based on financial performance is negatively related to risk taking as measured by R&D intensity. Results of a study of 184 major U.S. firms suggest that incentives based on short-term (annual) division financial performance are negatively related to total firm R&D intensity after controlling for industry R&D intensity, firm diversification, size and group structure. Furthermore, the results suggest that an emphasis on long-term financial incentives may mitigate the negative relationship between these incentives and R&D intensity, but does not promote risk taking. The results suggest the importance of emphasizing strategic controls [evaluating division managers based on operational understanding of strategies proposed (strategic criteria)] as opposed to the use of financial controls [evaluating division managers based on financial performance (often annual ROI)]. However, the use of financial controls becomes more common as firms diversify. Diversification increases the span of control of corporate executives and the diversity among divisions. In highly diversified firms, corporate executives are no longer able to fully understand the operations of the multiple and diverse divisions. Thus, they must not only decentralize operating authority to divisions, but they also cannot use strategic criteria to evaluate division managers. As a result, they begin to emphasize financial controls. The shift toward risk aversion caused by the use of incentives based on short-term financial outcomes can have important implications for long-term firm performance. The results of this study have implications for long-term competitiveness, especially for firms in R&D intensive industries where R&D expenditures may affect a firm's competitive position.
