Knowledge sharing facilitators in highly innovative manufacturing firms: Interaction terms shaping employees’ orientation in exchanging information

Knowledge is a critical resource for firms operating in dynamic markets, since their effectiveness strongly depends on internal knowledge exploitation. Accordingly, they need to carefully manage their knowledge assets by implementing appropriate knowledge sharing (KS) activities which allow employees to mutually exchange ideas, contributing to firm’s innovation and superior performance. However, knowledge is usually hard to transfer and employees may be reluctant in sharing what they know as they may lose power. This paper empirically tests a research model trying to expand the contribution of prior researches investigating the microfoundations of KS behaviours. By analyzing survey data of 754 workers from 24 international and highly innovative manufacturing firms, we provide empirical evidence about the important role played by employees’ enjoyment in helping others in supporting KS activities within the firm as well as about the moderation effect that macro-level variables (i.e. extrinsic rewards and organizational integrating mechanisms) have on our dependent variable (i.e. employees’ KS behaviours). We hope this paper may contribute to build a better understanding about the micro-foundations of knowledge processes, which call for first considering the primary role played by the individuals in influencing knowledge creation and knowledge sharing processes within the firm. We conclude the paper by offering managerial implications and directions for future studies.
A moderate reduction in extracellular pH protects macrophages against apoptosis induced by oxidized low density lipoprotein Published, JLR Papers in Press, January 17, 2008.

We investigated the effect of pH on macrophage apoptosis induced by oxidized low density lipoprotein (OxLDL), as human atherosclerotic lesions have regions of low pH. Hydroperoxide-rich and oxysterol-rich LDL caused 38% and 74% apoptosis of J774 macrophages, respectively, at 24 h, as measured by the externalization of phosphatidylserine. Native LDL, however, did not cause apoptosis. Reducing the pH of the culture medium from 7.4 to 7.0 inhibited apoptosis induced by hydroperoxide-rich or oxysterol-rich OxLDL by 61% and 46%, respectively (P < 0.001). These data were confirmed by semiquantitative analysis of cytochrome c release from mitochondria. Decreasing the extracellular pH to 7.0 reduced the uptake of hydroperoxide-rich and oxysterol-rich 125I-labeled LDL by 82% and 42%, respectively, and reduced cell surface binding of oxysterol-rich LDL by 31%. This may explain the reduced apoptosis. Additionally, low pH did not affect OxLDL-induced apoptosis of human monocytes, which do not possess scavenger receptors for OxLDL, but reduced apoptosis of human monocyte-derived macrophages, which do possess them. Our investigations suggest that the presence of areas of low pH within atherosclerotic lesions may reduce the uptake of OxLDL and reduce macrophage apoptosis, thus affecting lesion progression.
Subtle and Ineffable Tree Properties

In the style of the tree property, we give combinatorial principles that capture the concepts of the so-called subtle and ineffable cardinals in such a way that they are also applicable to small cardinals. Building upon these principles we then develop a further one that even achieves this for supercompactness. We show the consistency of these principles starting from the corresponding large cardinals. Furthermore we show the equiconsistency for subtle and ineffable. For supercompactness, utilizing the failure of square we prove that the best currently known lower bounds for consistency strength in general can be applied. The main result of the thesis is the theorem that the Proper Forcing Axiom implies the principle corresponding to supercompactness.
The Sustainability Footprint of Institutional Investors: ESG Driven Price Pressure and Performance

Institutional investors are the single most important class of shareholders in stock markets. Yet, knowledge about their motivations for embedding environmental and social — or more generally — sustainability considerations in their portfolio allocations is at best emerging. In this paper, we propose a novel approach to measure the environmental, social, and aggregate sustainability footprint at the institutional investor portfolio-level. We provide evidence that institutional investors with longer investment horizons — as measured by investors’ legal type or portfolio turnover — exhibit significantly better sustainability footprints. We also document that institutional investors with better sustainability footprints generate higher risk-adjusted performance, primarily through a reduction of portfolio risk. Overall, our results are consistent with the view that institutional investors choose sustainability oriented portfolio allocations with the objective of long-term value maximization.
Tax Complaints Classification on Twitter Using Text Mining

Twitter growth and utilization encourage the emergence of limitless textual information so that people can express their complaints easily This leads the Directorate General of Taxation uses twitter to deal with tax complaints faced by the community. However, the messages on twitter can contain any information, either the tax complaint or not. This will cause difficulties in handling complaints process. It is important to automatically identify so tax complaint handling can be done effectively and efficiently. Given these problems, it is necessary to do the twitter tax complaint classification with the support of text mining. There are several methods of classification such as Naive Bayes classifiers, Support Vector Machine (SVM) and Decision Tree. This research aims to classify the tax complaint on twitter automatically by using text mining. The experimental results show the value of f-measure of SVM, Naive Bayes and Decision Tree, respectively, are 89.3%, 85.6% and 76.9%
The Relationships Among Recruiter Characteristics and Pre-and Post-hire Recruitment Outcomes

Previous research on recruiter characteristics has generally focused on recruitment outcomes related to generating applicants and maintaining their interest. The current study expanded previous research by examining recruitment outcomes at preand posthire stages of the recruitment process. These outcomes included time to fill position, job offer acceptance rate, job fit, job satisfaction, and retention. Findings indicate that recruiter conscientiousness compared to extraversion is most consistently associated with pre-hire outcomes such as time to fill position and accepting hiring recommendations. Conscientiousness was also related to note-taking in the interview. Recruiter informativeness and personableness were associated with hiring managers' and new hires’ satisfaction with the hiring process. Finally, recruiter informativeness was related to new hires’ post-hire attitudes.
Lipopolysaccharide precipitates hepatic encephalopathy and increases blood–brain barrier permeability in mice with acute liver failure

Acute liver failure (ALF) is frequently complicated by infection leading to precipitation of central nervous system complications such as hepatic encephalopathy (HE) and increased mortality. There is evidence to suggest that when infection occurs in ALF patients, the resulting pro‐inflammatory mechanisms may be amplified that could, in turn, have a major impact on blood–brain barrier (BBB) function. The aim of this study was to investigate the role of endotoxemia on the progression of encephalopathy in relation to BBB permeability during ALF.
A brief inventory of sand flies (Diptera, Psychodidae) from the National Forest of the Rio Preto, state of the Espírito Santo, southeastern Brazil

The inventories on sand flies are usually conducted for a long period in leishmaniasis-endemic regions. Thus, there is little data on the sand fly fauna in areas where no leishmaniasis cases have been reported. Therefore, we conducted an inventory to study the sand fly fauna in the National Forest of Rio Preto (NFRP). We carried out a brief inventory by using four CDC light traps in 2009 during winter and summer. We collected 1,403 sand flies belonging to 11 genera and 22 species. As expected, we did not find in the NFRP region sand flies species that have been reported as vectors of Leishmania. However, we found some species of sand flies with few records and that rarely have been reported in southeastern Brazil. Nevertheless, the diversity and species richness of the sand flies in NFRP were similar to those reported in other Atlantic Forest conservation areas. Hence, we drew the following conclusions: (i) it is necessary to carry out inventories not only in leishmaniasis-endemic areas but also in areas with no records of this disease; and (ii) brief inventories can be useful in describing the sand fly fauna in such areas.
Enhancing public project implementation in Botswana during the NDP 11 period

Successful project implementation is critical in development planning. If there is poor project implementation, economic development will be stalled. Generally, public project implementation has a chequered history. This is particularly true in developing countries which are characterised by low levels of project management maturity. The objective of this article is to review public project implementation in Botswana and recommend improvements for the National Development Plan (NDP) 11 period (2017/2018-2022/2023). The article used the survey strategy and adopted the descriptive approach. Data collection sources were mixed, that is, primary and secondary sources. It concluded that public projects are either poorly implemented (i.e. not implemented in accordance with the ‘Project Management Triple Constraint’ of cost, time and scope) or not implemented at all. Given a constrained revenue envelope post 2008, there is a need for improved project implementation. Amongst others, this calls for professional public project implementation so that NDPs become a reality.
- 1-Altered autonomic nervous system activity as a potential etiological factor of premenstrual syndrome and premenstrual dysphoric disorder

Altered autonomic nervous system activity as a potential etiological factor of premenstrual syndrome and premenstrual dysphoric disorder BioPsychoSocial Medicine 2007, 1:24 doi:10.1186/1751-0759-1-24 Tamaki Matsumoto (tamaki@shitennoji.ac.jp) Takahisa Ushiroyama (t-ushiroyama@ns-t.aino.ac.jp) Tetsuya Kimura (kimura@mmg.mbox.media.kyoto-u.ac.jp) Tatsuya Hayashi (tatsuya@kuhp.kyoto-u.ac.jp) Toshio Moritani (t.moritani@neuro.mbox.media.kyoto-u.ac.jp)
Antenatal Use of Selective Serotonin-Reuptake Inhibitors and QT Interval Prolongation in Newborns

OBJECTIVES. Prolongation of the QT interval is a risk factor for sudden death. Selective serotonin-reuptake inhibitor antidepressants can prolong the QT interval and are widely used by pregnant women. Whether antenatal exposure to selective serotonin-reuptake inhibitor causes QT prolongation in offspring is unknown. The aim of this study was to determine the effect of maternal use of selective serotonin-reuptake inhibitor antidepressants during pregnancy on the QTc interval of the offspring. METHODS. Between January 2000 and December 2005, we collected data on all of the newborns born at a single tertiary care hospital. Electrocardiograms of infants exposed to selective serotonin-reuptake inhibitor antidepressants in utero were compared with those of healthy control newborns matched on gestational age. The tracings were interpreted by a pediatric cardiologist who was unaware of the drug exposure. RESULTS. We identified 52 newborns exposed to selective serotonin-reuptake inhibitor antidepressants in the immediate antepartum period and 52 matched control subjects. The mean QTc was significantly longer in the group of newborns exposed to antidepressants as compared with control subjects (409 ± 42 vs 392 ± 29 milliseconds). Five (10%) newborns exposed to selective serotonin-reuptake inhibitor antidepressants had a markedly prolonged QTc interval (>460 milliseconds) compared with none of the unexposed newborns. The longest QTc interval observed among exposed newborns was 543 milliseconds. All of the drug-associated repolarization abnormalities normalized in subsequent electrocardiographic tracings. CONCLUSIONS. Antepartum use of selective serotonin-reuptake inhibitor antidepressants is associated with QTc interval prolongation in exposed neonates. Additional research using a standardized protocol is needed to determine whether exposure to selective serotonin-reuptake inhibitor antidepressants in late pregnancy is also associated with arrhythmias.
12 . 2 The hand

Hand dysfunction is commonly linked to ligamentous laxity (Murray 2006). The carpometacarpal joint (CMCJ) of the thumb may be particularly susceptible to weakened ligamentous constraints in the Ehlers-Danlos syndrome (Moore et al 1985). Symptoms may only present if the joint has been subject to excessive trauma, overuse or misuse and thus strains of the surrounding muscles and ligaments may have developed (Wynn Parry 2000). In this chapter, assessment and treatment principles for the hypermobile hand will be discussed, including joint protection advice, energy conservation techniques, strengthening exercises, proprioceptive retraining and surgical principles. In particular, the impact of hypermobility in the hand is explored in relation to musicians, who are often hypermobile, and in relation to writing, which can also be significantly affected by the presence of hypermobility in both adults and children. Musical instrument modifications, writing retraining and the relationship between hypermobility and the development of osteoarthritis will be presented.
ALMA Memo No . 410 Designing and Prototyping of 2-4 GHz Bandpass SiGe Digitizers and Associated Test Equipment for the ALMA Project

In this first paper we describe the approach followed to design and experimentally test the high speed and broad band analog-to-digital converters (ADC's or digitizers) required for the ALMA project. Our prototypes are based on monolithic digitizers implemented in a BiCMOS 0.35 or 0.25 μm SiGe process with 3 or 8 quantization levels and 4 giga samples per second rate for an input signal from 2 to 4 GHz under full Nyquist condition. We have adopted a conventional flash converter architecture to design three different 2-bit digitizers and one 3-bit digitizer. The experimental results obtained with our first 2-bit digitizer ASIC show that sinusoidal input signals are properly sampled for clock rates up to 4.9 GHz. The design details and high dynamic range tests of our ADC's will be reported in forthcoming papers. A specific digitizer test equipment providing the auto-correlation and spectral analysis of the digitized signal has been developed to characterize our designs and provide the necessary feedback to the ASIC design team. It includes a broad band noise generator, a demultiplexing unit following the digitizer under test, a 16-lag auto-correlator, and FFT and display units. This equipment will also play a major role at the pre-production stage and for qualification/acceptance at the production stage. We suggest that the demultiplexing scheme developed for the digitizer test equipment could be used as a basis for multi-bit synchronization of the demultiplexed signal in front of the ALMA fiber optic transmitter system.
Strontium disodium hexathiodiphosphate(IV) octahydrate

The crystal structure of SrNa2(P2S6)·8H2O is isotypic with that of its calcium analogue. The asymmetric unit consists of one Sr2+ cation (2 symmetry), two Na+ cations (2 and symmetry, respectively), one-half of a centrosymmetric (P2S6)4− anion with a staggered confirmation and four water molecules. The crystal structure is built up from layers of cations and anions extending parallel to (101). Each SrO8 polyhedron is connected via edge-sharing to two NaO4S2 octahedra and to one NaO2S4 octahedron. The NaO4S2 octaedra are, in turn, connected with two (P2S6)4− anions through common corners. Adjacent layers are held together by several O—H⋯S hydrogen-bonding interactions.
Protective Effects of Aqueous Extracts of Cinnamon and Ginger Herbs Against Obesity and Diabetes in Obese Diabetic Rat

The effects of cinnamon aqueous extract (CAE) and ginger aqueous extract (GAE) on body weight and fats, serum levels of liver enzymes, blood lipids, glucose, leptin and insulin and on the activity of tissue antioxidant enzymes in obese diabetic rats were evaluated. Fifty four male Sprague Dawley rats were randomized into 6 equal groups. Group (1) was fed on basal diet, while the other 5 groups were fed on high-fat diet (HFD) for 6 weeks to induce obesity and acute hyperlipidemia. The obese rats were then rendered diabetic by intraperitoneal injection of alloxan (120 mg/kg/day) for 5 days. After induction of diabetes, group (2) was kept obese diabetic and the other 4 groups were orally given CWE in doses 100 and 200 mg/kg or GWE in doses 100 and 200 mg/kg, respectively, for 6 weeks. Blood samples were collected for separating the serum for biochemical analyses. Kidneys were dissected out and prepared to assay activities of tissue antioxidant enzymes. The results showed that oral administration of CAE and GWE to obese diabetic rats significantly reduced body weight and fats; decreased serum levels of aspartate aminotransferase, alanine aminotransferase and gamma-glutamyl transpeptidase enzymes, total cholesterol, triglycerides and low density lipoprotein and reduced atherogenic index (LDL-c/HDL-c). There were significant decreases in blood glucose and leptin hormone and increase in insulin in obese diabetic rats given CAE and GWE. The extracts also increased activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) antioxidant enzymes in kidney tissues of obese diabetic rats. In conclusion, cinnamon and ginger extracts produce anti-obesity, antidiabetic, hypolipidemic and antioxidant effects in obese diabetic rats. These results provide scientific evidence to substantiate the traditional use of cinnamon and ginger as a drink in treating obesity, hyperlipidemia and diabetes.
Male reproductive health--what is the GP's role?

BACKGROUND Male reproductive health issues cause considerable morbidity, as well as mortality, in our community. Although 'women's health' has been a separate and important subject of medical interest for many years, it is only recently that the study of male health, andrology, has gained impetus as an area of research and clinical importance. OBJECTIVE This article outlines the current issues and recent advances in men's reproductive health. DISCUSSION Despite publicity in the popular press about erectile dysfunction it remains an under treated, treatable condition, with close association with increased cardiovascular risk. The advent of intracytoplasmic sperm injection has significantly improved the management of male infertility. Testicular cancer now has an excellent prognosis and, while screening for prostate cancer remains a controversial area, prostate cancer mortality appears to be declining. As general practitioners we need to keep abreast of developments in male reproductive health, know how to sensitively question our male patients about their concerns and to deal effectively with the answers we receive.
Private Equity and the Resolution of Financial Distress

We examine the role private equity (PE) sponsors play in the resolution of financial distress of portfolio companies. PE-backed firms have higher leverage and default at higher rates than other companies borrowing in leveraged loan markets. But, PE-backed firms restructure more quickly, avoid bankruptcy court more often, and liquidate less often compared to other highly leveraged firms experiencing financial distress. PE owners are also more likely to retain control post-restructuring, often by infusing capital as firms approach distress. While default frequencies are higher among PE-backed firms, PE investors appear to manage financial distress at lower cost compared to other owners.
The MEP2 ammonium permease regulates pseudohyphal differentiation in Saccharomyces cerevisiae

In response to nitrogen starvation, diploid cells of the budding yeast Saccharomyces cerevisiae differentiate into a filamentous, pseudohyphal growth form. This dimorphic transition is regulated by the Gα protein GPA2, by RAS2, and by elements of the pheromone‐responsive MAP kinase cascade, yet the mechanisms by which nitrogen starvation is sensed remain unclear. We have found that MEP2, a high affinity ammonium permease, is required for pseudohyphal differentiation in response to ammonium limitation. In contrast, MEP1 and MEP3, which are lower affinity ammonium permeases, are not required for filamentous growth. Δmep2 mutant strains had no defects in growth rates or ammonium uptake, even at limiting ammonium concentrations. The pseudohyphal defect of Δmep2/Δmep2 strains was suppressed by dominant active GPA2 or RAS2 mutations and by addition of exogenous cAMP, but was not suppressed by activated alleles of the MAP kinase pathway. Analysis of MEP1/MEP2 hybrid proteins identified a small intracellular loop of MEP2 involved in the pseudohyphal regulatory function. In addition, mutations in GLN3, URE2 and NPR1, which abrogate MEP2 expression or stability, also conferred pseudohyphal growth defects. We propose that MEP2 is an ammonium sensor, generating a signal to regulate filamentous growth in response to ammonium starvation.
Field measurement of nickel sediment toxicity: Role of acid volatile sulfide

A field experiment was performed in four freshwater systems to assess the effects of Ni on the benthic macroinvertebrate communities. Sediments were collected from the sites (in Belgium, Germany, and Italy), spiked with Ni, and returned to the respective field sites. The colonization process of the benthic communities was monitored during a nine‐month period. Nickel effect on the benthos was also assessed in the context of equilibrium partitioning model based on acid volatile sulfides (AVS) and simultaneously extracted metals (SEM). Benthic communities were not affected at (SEM − AVS) ≤ 0.4 µmol/g, (SEM − AVS)/fraction of organic carbon (fOC) < 21 µmol/g organic carbon (OC). Sediments with (SEM − AVS) > 2 µmol/g, (SEM − AVS)/fOC > 700 µmol/g OC resulted in clear adverse effects. Uncertainty about the presence and absence of Ni toxicity occurred at (SEM − AVS) and (SEM − AVS)/fOC between 0.4 to 2 µmol/g and 21 to 700 µmol/g OC, respectively. The results of our study also indicate that when applying the SEM:AVS concept for predicting metal toxicity in the field study, stressors other than sediment characteristics (e.g., sorption capacity), such as environmental disturbances, should be considered, and the results should be carefully interpreted.

Dynamically Managing a Profitable Email Marketing Program

Although email marketing is highly profitable and widely used by marketers, it has received limited attention in the marketing literature. Extant research has focused on either customers’ email responses or the “average” effect of emails on purchases. In this article, the authors use data from a U.S. home improvement retailer to study customers’ email open and purchase behaviors by using a unified hidden Markov and copula framework. Contrary to conventional wisdom, the authors find that email-active customers are not necessarily active in purchases, and vice versa. Furthermore, the number of emails sent by the retailer has a nonlinear effect on both the retailer's short- and long-term profitability. Through a counterfactual study, the authors provide a decision support system to guide retailers in making optimal email contact decisions. This study shows that sending the right number of emails is vital for long-term profitability. For example, sending four (ten) emails instead of the optimal number of seven emails can cause the retailer to lose 32% (16%) of its lifetime profit per customer.
