“Knowledge Transfer Within the Firm: A Replication Perspective on Stickiness”

Generative mechanisms underlying stickiness remain largely unspecified in extant research. This constrains the interpretation of available findings and the derivation of normative implications from them. The replication perspective that we suggest in this paper allows us to specify a generative mechanism that underlies stickiness. We hypothesize and test the notion that accuracy mediates the relationship between stickiness and its predictors. Our analysis relies on a sample of 122 transfers of best practices within eight firms. (75 WORDS)
Is audience engagement worth the buzz? The value of audience engagement, comment reading, and content for online news brands

Online audience engagement, such as rating or sharing news, commenting or creating content, can enhance users’ loyalty toward online news brands. Yet recently, uncertainties have been discussed within journalism research and practice concerning the handling of online comment sections and potential negative influences – caused through comment reading – on news brands. From a brand management perspective, audience engagement and comment reading can affect a brand’s equity. This study investigates the value of audience engagement and comment reading for the customer-based brand equity of online news outlets. An online survey with n = 313 users of the digital native cohort revealed that comment reading is neither directly beneficial nor harmful for online news brands. However, for brands providing hard news comment reading seems more likely to have negative than positive relations with CBBE than for brands with other content. Sharing and liking news are associated with a stronger perceived brand quality, loyalty, and associations. User-generated content creation including commenting does not enhance customer-based brand equity. Overall, serious content proved to be a stronger driver of news brand value than any form of audience engagement.
Increasing COPD awareness

Early diagnosis and smoking cessation are the only available methods to stop the progression of chronic obstructive pulmonary disease (COPD). The aim of this study was to evaluate the effects of early detection of airflow limitation (AL) in a population with high risk for COPD, using spirometric screening. Smokers aged 40 yrs with a smoking history of 10 pack-yrs were invited to visit a local outpatient chest clinic for simple spirometry (forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)). Smoking history was recorded, followed by smoking cessation advice relating the results of spirometry to the smoking behaviour. Subjects who did not fulfil the above criteria (younger and/or nonsmokers) were also screened. A total 110,355 subjects were investigated; they were aged 53.5+/-11.5 yrs and 58.2% were males. Of the total amount of subjects, 64% were current smokers, 25.1% were former smokers and 10.9% were lifelong nonsmokers. Spirometry tests were within normal values for 70.3%, and 20.3% showed signs of AL: this was mild in 7.6%, moderate in 6.7% and severe in 5.9%. The remaining 8.3% of subjects presented with a restrictive pattern of ventilatory impairment. Airflow limitation was found in 23% of smokers aged 40 yrs with a history of 10 pack-yrs. This study concluded that large-scale voluntary spirometry screening of the population with high risk for COPD detects a large number of subjects with AL.
The Implications of a High Academic Ability Learning Environment on Third Grade Gifted Students' Academic Achievement in Florida Public Schools

The purpose of this two year study was to investigate the implications of a high academic ability learning environment on the achievement scores of third grade gifted students who attended the Florida Brevard County Public School System. Learning environment was defined by the students' academic ability level, whether high academic ability or heterogeneous academic ability, and for this study was the independent variable. Academic achievement, as measured by the 2011 and the 2012 Florida Comprehensive Assessment Test&"174; 2.0 (FCAT 2.0) Mathematics and Reading Developmental Scale Scores (DSS), was the dependent variable. Other student data such as gender and socioeconomic status were also collected and used along with classroom structure to examine the extent to which third grade gifted students' reading and mathematics performance could be predicted. Random samples of students were drawn from the third grade gifted student population attending Florida Brevard County Public School System in the 2010-2011 and the 2011-2012 school years. Using an independent samples t-test, analysis of the 2011 FCAT 2.0 Reading and Mathematics found a statistically significant difference in both the students' FCAT 2.0 Mathematics and the students' FCAT 2.0 Reading achievement test scores based on the classroom structure. Specifically, there was enough evidence to support the claim that third grade gifted students who learned in a homogeneous high academic ability learning environment scored significantly higher on reading and mathematics standardize tests than did third grade gifted students who learned in a heterogeneous academic ability learning environment. Approximately 14% of the variance in reading and mathematics scores could be accounted for by classroom structure. However, different results were found with the 2012 FCAT 2.0 Mathematics and Reading scores. The results from the 2011-2012 school year indicated that there was not a significant difference in mean reading and mathematics scores between third grade gifted students who learn in a homogeneous high academic ability learning environment and third grade gifted students who learn in a heterogeneous academic ability learning environment. The recommendations include that subsequent studies incorporate a wider range of grade levels, perhaps even include methods of instructional delivery, types of gifted services provided, and teachers' years of experience. In addition, recommendations are that future studies address the academic performance of high academic ability non-gifted students who learn in homogeneous high academic ability classroom environments verses those who learn in heterogeneous academic ability classroom structures.
Justification: a Not Fully Exploited Technique

The objective of this paper is to show that justification is a simple technique that can be easily incorporated in diverse algorithms for the resource-constrained project scheduling problem – improving the quality of the schedules generated without generally requiring more computing time. The results of incorporating this technique in 21 different algorithms are shown. Fourteen of the new algorithms that use double justification outperform six of the best heuristic algorithms that do not use justification. The tests have been performed on the standard test set j120 for the RCPSP generated using ProGen.
THE EFFECTS OF BARORECEPTOR STIMULATION ON SHORT-TERM VERBAL MEMORY

Individuals remember arousing, emotional stimuli better than neutral. Vagus nerve stimulation (VNS) has been associated with changes in such 'affective memory' in clinical samples. The current study utilized carotid baroreceptor stimulation (CBS), an indirect method of vagus nerve stimulation, to investigate this association further in normal, college-aged participants. Results showed that CBS marginally enhanced verbal memory for negative words and slowed heart rate, but these effects were not robust. Our findings indicate that physiological manipulations may contribute to differential rates of memory for arousing, emotional stimuli, suggesting that preferential memory for such stimuli might be attributed, in part, to individual differences in physiology. These findings are discussed within both the context of the Laceys' (1974) hypothesis that baro-afferent signaling may be associated with concomitant changes in heart rate and cognitive function and from the perspective that stimulation may affect brain regions involved in emotion and memory processing.
An optimal RAM implementation of catenable min double-ended queues

We consider the implementation of generalized doubled-ended queues. The generalized data structure, which is denoted as mindeque, allows the standard deque operations and also the additional operations of catenation and findmin. We first present a simple RAM algorithm that achieves an amortized O(1) RAM steps per mindeque operation. We then develop a more complex RAM algorithm that performs worst case O(1) steps per mindeque operation, solving an open problem posed by Buchsbaum, et al. We also develop a simple accounting procedure for establishing that bottom-up insert, delete and join operations on balanced binary trees have an 0( 1) amortized speed.
Stochastic Flocculation Model for Cohesive Sediment Suspended in Water

Existing flocculation models for cohesive sediments are classified into two groups: population balance equation models (PBE) and floc growth models. An FGM ensures mass conservation in a closed system. However, an FGM determines only the average size of flocs, whereas a PBE has the capability to calculate a size distribution of flocs. A new stochastic approach to model the flocculation process is theoretically developed and incorporated into a deterministic FGM in this study in order to calculate a size distribution of flocs as well as the average size. A log-normal distribution is used to generate random numbers based on previous laboratory experiments. The new stochastic flocculation model is tested with three laboratory experiment results. It was found and validated with measured data that the new stochastic flocculation model has the capability to replicate a size distribution of flocs reasonably well under different sediment and carrier flow conditions. Three more distributions (normal; Pearson type 3; and generalized extreme value distributions) were also tested. From the comparison with results of different distribution functions, it is shown that a stochastic FGM using a log-normal distribution has a comparative advantage in terms of simplicity and accuracy.
Optimization of microstrip dual-band filter with implicit space mapping algorithm

An effective optimization scheme based on improved implicit space mapping (ISM) algorithm is presented in this paper for the first time to design microstrip dual-band bandpass filters with high performance. The 2.45GHz/5.7GHz and 3.5 GHz/5.25GHz dual-band filters using folded open-loop ring resonators (OLRRs) are implemented with satisfying passband and stopband response. The overall size of the previous filter is 17mm×8mm, nearly one-third smaller than the literature result 26mm×8mm, and the capability is also better. The latter one is 18mm×8mm, both are applicable for miniaturization system
Cooperating Music Teachers’ Opinions Regarding the Importance of Selected Traits as Predictors of Successful Student Teaching Experiences

The purpose of the study was to determine the perceptions of cooperating mentor teachers regarding the importance of certain teacher traits as predictors of a successful student teaching experience. The data collection tool used in this study was an online survey which participants could complete online in approximately 10-15 minutes. The entire survey included 91 total questions; however, participants were presented with 54 questions to answer based on their responses to previous questions. The 54 questions included a consent statement, 40 four-point Likert-type scale responses, three multiple-selection questions, three open-ended responses, and seven demographic questions. The population targeted for this study was cooperating mentor teachers for preservice music education majors throughout the United States. Recruitment methods for this study included a combination of snowball sampling and an email soliciting participation that was sent nation-wide to music educators across the United States through the National Association for Music Education (NAfME). The snowball iv sampling method resulted in approximately 100 participants and the rest were recruited through the solicitation sent email by NAfME. Surveys from participants who either did not complete the survey fully, or who did not fit the inclusion criteria were discarded, resulting in a total of 519 surveys analyzed for this study. A combination of descriptive and inferential statistics was used to analyze participant data. Descriptive data were utilized to construct ranked lists of teacher traits based on the mean importance ratings of each respondent group. Inferential statistics used in this study included Analysis of Variance (ANOVA) tests and post-hoc protected t-tests. Cooperating teachers assigned highest importance ratings to the following teacher traits: demonstrating appropriate social behavior, stress management, fostering appropriate student behavior, establishing a positive rapport with others, and enthusiasm. Comparisons among band, orchestra, choral and general music teachers yielded the most variability when examining teacher traits as ordered lists based on the mean ratings of cooperating teachers. All participant groups rated personal traits as most important, followed by teaching traits, then musical traits. Content analyses of open-ended questions revealed that no teacher traits had a universal meaning or description among participants in this study.
“Let Me Take a Selfie”: Associations Between Self-Photography, Narcissism, and Self-Esteem

The proliferation of social media in day-to-day life has raised numerous questions about how individuals present themselves in these arenas. The present study examined the associations of narcissism and self-esteem with the posting of self-photographs (“selfies”) on a popular photo sharing social networking site (i.e., Instagram). Participants were 128 undergraduate students (19 males, 109 females) ranging in age from 18 to 43 (M = 20.46, SD = 3.59). Selfies were coded according to their frequency relative to participants’ nonselfie posts and their apparent themes (i.e., physical appearance, activity/event/location, affiliation with others, collage, other/undifferentiated). The hypothesized relations of narcissism and self-esteem with the posting of selfies independent of theme were not significant. However, there was a significant relation between some dimensions of narcissism and specific categories of selfies (e.g., vulnerable narcissism with physical appearance selfies). The limitations of the present study, particularly in terms of sampling and other issues that may influence online presentations, as well as the implications for future research on social media photographic displays are discussed.
Interleukin (IL)-1 Receptor–associated Kinase (IRAK) Requirement for Optimal Induction of Multiple IL-1 Signaling Pathways and IL-6 Production

Interleukin (IL)-1 is a proinflammatory cytokine with pleiotropic effects in inflammation. IL-1 binding to its receptor triggers a cascade of signaling events, including activation of the stress-activated mitogen-activated protein (MAP) kinases, c-Jun NH2-terminal kinase (JNK) and p38 MAP kinase, as well as transcription factor nuclear factor κB (NF-κB). IL-1 signaling results in cellular responses through induction of inflammatory gene products such as IL-6. One of the earliest events in IL-1 signaling is the rapid interaction of IL-1 receptor–associated kinases, IRAK and IRAK-2, with the receptor complex. The relative roles of IRAK and IRAK-2 in IL-1 signaling pathways and subsequent cellular responses have not been previously determined. To evaluate the importance of IRAK in IL-1 signaling, IRAK-deficient mouse fibroblast cells were prepared and studied. Here we report that IL-1–mediated activation of JNK, p38, and NF-κB were all reduced in embryonic fibroblasts deficient in IRAK expression. In addition, IL-6 production in response to IL-1 was also dramatically reduced in IRAK-deficient embryonic fibroblasts and in skin fibroblasts prepared from IRAK-deficient mice. Our results demonstrate that IRAK plays an essential proximal role in coordinating multiple IL-1 signaling pathways for optimal induction of cellular responses.
Re-ranking for person re-identification

Person Re-Identification problem aims at matching people across a network of non-overlapping cameras. When multiple probe people appear concurrently, human could compare them together to give a more accurate matching. However, existing approaches treat each probe person independently, skipping the concurrent information. In this paper, we propose a re-ranking method which utilize that kind of information to refine ranked lists produced by any person re-identification method to create more precise ranked lists. The experimental results on VIPeR dataset show the improved performance when our method is applied.
American-Style Indexed Executive Stock Options

This paper develops a new pricing model for American-style indexed executive stock options. We rely on a basic model framework and an indexation scheme first proposed by Johnson and Tian (2000a) in their analysis of European-style indexed options. Our derivation of the valuation formula represents an instructive example of the usefulness of the change-of-numeraire technique. In the paper's numerical section we implement the valuation formula and demonstrate that not only may the early exercise premium be significant but also that the delta of the American-style option is typically much larger than the delta of the otherwise identical (value-matched) European-style option. Vega is higher for indexed options than for conventional options but largely independent of whether the options are European- or American-style. This has important implications for the design of executive compensation contracts. We finally extend the analysis to cover the case where the option contracts are subject to delayed vesting. We show that for realistic parameter values, delayed vesting leads only to a moderate reduction in the value of the American-style indexed executive stock option. JEL classifications: G13, G34, J33.
High School Students Are a Target Group for Fight against Self-Medication with Antimalarial Drugs: A Pilot Study in University of Kinshasa, Democratic Republic of Congo

Aim. To assess the self-medication against malaria infection in population of Congolese students in Kinshasa, Democratic Republic of Congo (DRC). Methods. A cross-sectional study was carried out in University of Kinshasa, Kinshasa, Democratic Republic of Congo. Medical records of all students with malaria admitted to Centre de Santé Universitaire of University of Kinshasa from January 1, 2008, to April 30, 2008, were reviewed retrospectively. Results. The median age of the patients was 25.4 years (range: from 18 to 36 years). The majority of them were male (67.9%). Artemisinin-based combination treatments (ACTs) was the most used self-prescribed antimalarial drugs. However, self-medication was associated with the ingestion of quinine in 19.9% of cases. No case of ingestion of artesunate/artemether in monotherapy was found. All the medicines taken were registered in DRC. In this series, self-prescribed antimalarial was very irrational in terms of dose and duration of treatment. Conclusion. This paper highlights self-medication by a group who should be aware of malaria treatment protocols. The level of self-prescribing quinine is relatively high among students and is disturbing for a molecule reserved for severe disease in Congolese health care policy in management of malaria.
Rescaling the local: multi-academy trusts, private monopoly and statecraft in England

ABSTRACT For the past six years successive UK governments in England have introduced reforms intended to usher in less aggregated, top-down, bureaucratically overloaded models of service delivery. Yet the ‘hollowing out’ of local government has not resulted in less bureaucracy on the ground or less regulation from above, nor has it diminished hierarchy as an organising principle of education governance. Monopolies and monopolistic practices dominated by powerful bureaucracies and professional groups persist, albeit realised through the involvement of new actors and organisations from business and philanthropy. In this paper I adopt a governmentality perspective to explore the political significance of large multi-academy trusts (MATs) – private sponsors contracted by central government to run publicly funded schools – to the generation of new scalar hierarchies and accountability infrastructures that assist in bringing the gaze of government to bear upon the actions of schools that are otherwise less visible under local government management.
Cheap Talk Games: Comparing Direct and Simplified Replications

To study strategic information transmission in organizations, we conduct a simplified version (with only three states) of the sender-receiver game experiment designed by Wang, Spezio, and Camerer (2010), in which an informative sender advises an uninformed receiver to take an action (to match the true state), but has incentives to exaggerate. We also have the same subjects play the original five-state game. We find similar “overcommunication” behavior with Taiwanese subjects – messages reveal more information about the true state than what equilibrium predicts – that let us classify subjects into various level-k types. However, results from the simplified version are closer to equilibrium prediction, with more senders robustly classified as level-2.
Bayesian Networks for Fault Detection under Lack of Historical Data

In this paper we propose a Bayesian Network approach as a promissory data fusion technique for surveillance of sensors accuracy. We prove the usefulness of this method even in case when there is not enough feasible data to construct the model in traditional way. In presence of this data constrains we suggest an inversion of the causal relationship. This approach proves to be a possible solution to help the expert in the conditional probabilities assessment process. As a result a working model is constructed what would not be possible using traditional Bayesian Network approach.
Comparison of Mobile-Bearing and Fixed-Bearing Designs in High Flexion Total Knee Arthroplasty: Using a Navigation System

Purpose We compared and analyzed the short term results of high flexion total knee arthroplasty (TKA) with mobile-bearing and fixed bearing designs. Materials and Methods We studied 32 patients that had undergone TKA with LPS-Flex Mobile and 34 patients with LPS-Flex Fixed using an electromagnetic navigation system between January 2010 and June 2010, and were followed up for at least 1 year. Results Knee Society Functional Score (KSFS) and Knee Society Knee Score (KSKS) of the mobile-bearing group were 94.5 and 93.8 points, respectively, and were 48.2 and 45.3 points preoperatively, whereas those of the fixed-bearing group were 95.1 and 94.2 points, respectively, and were 49.5 and 46.9 points preoperatively. Postoperative mechanical axis deviation and implant position of the femoral and tibial component both on the coronal and sigittal planes showed no significant differences between the two groups. Range of motion (ROM) and maximal flexion angle (MFA) of the knee joint also showed no significant differences between the two groups. The possibility of crossed-legged sitting and kneeling position also showed no significant differences between the two groups. Conclusions Clinical and radiologic parameters, ROM and MFA of knee joints showed no significant differences in both the groups, but long term follow-up results may be necessary, including survival rate.
