Authentic Leadership and Employees’ Innovative Behaviour: A Multilevel Investigation in Three Countries

The innovativeness of individual employees is a vital source of competitive advantage of firms, contributing to societal development. Therefore, the aim of this multilevel study was to examine how entrepreneurial firm owners’ authentic leadership relates to their employees’ innovative behaviour. Our conceptual model postulates that the relationship between business owners’ authentic leadership (as perceived by their employees) and their employees’ innovative behaviour is mediated by employees’ personal initiative and their work engagement. Hypotheses derived from this model were tested on data collected from 711 employees working in 85 small firms from three European countries: the Netherlands, Poland, and Spain. The results of the multilevel modelling confirmed our model, showing that when business owners are perceived as more authentic leaders, their employees show higher personal initiative and are more engaged at work and, in turn, identify more innovative solutions to be implemented in the organization. A cross-national difference was observed: employees from Spain (in comparison to Dutch and Polish employees) reported engaging less frequently in innovative behaviour. These research findings suggest that the innovative behaviour of employees can be boosted through leadership training, improving the quality of relationships between leaders and subordinates, and strengthening employees’ personal initiative and work engagement.
Detection of Voltage Anomalies in Spacecraft Storage Batteries Based on a Deep Belief Network

For a spacecraft, its power system is vital to its normal operation and capacity to complete flight missions. The storage battery is an essential component of a power system. As a spacecraft spends more time in orbit and its storage battery undergoes charge/discharge cycles, the performance of its storage battery will gradually decline, resulting in abnormal multivariate correlations between the various parameters of the storage battery system. When these anomalies reach a certain level, battery failure will occur. Therefore, the detection of spacecraft storage battery anomalies in a timely and accurate fashion is of great importance to the in-orbit operation, maintenance and management of a spacecraft. Thus, in this study, based on storage battery-related telemetry parameter data (including charge/discharge currents, voltages, temperatures and times) downloaded from an in-orbit satellite, a voltage anomaly detection algorithm for spacecraft storage batteries based on a deep belief network (DBN) is proposed. By establishing a neural network (NN) model depicting the correlations between each of the variables of temperature, current, pressure and charge/discharge times and voltage, this algorithm supports the detection of anomalies in the state-of-health of a storage battery in a timely fashion. The proposed algorithm is subsequently applied to the storage battery of the aforementioned in-orbit satellite. The results show the following. The anomalies detected using the proposed algorithm are more reliable, effective and visual than those obtained using the conventional multivariate anomaly detection algorithms. Compared to the classic backpropagation NN-based algorithm, the DBN-based algorithm is notably advantageous in terms of the model training time and convergence.
A New Perspective of the Intellectual Capital Dynamics in Organizations

The concept of intellectual capital (IC) is a fuzzy concept, due to its various definitions and theories developed so far. Although it is a powerful concept, it is difficult to figure out how to measure it, due to its intangible nature. As Sullivan remarked (1998, p.19), “discussing intellectual capital management can be a frustrating experience. Conversations that begin with apparent understanding can soon become confused and unclear”. This explanation comes from the semantic dynamics of the concept in time, and from the spectrum of meanings attached to this concept in different organizational contexts. Although IC studies have an intrinsic interdisciplinary nature, there is little cross-communication between researchers representing different backgrounds. However, despite all of these difficulties, we can intuitively understand the core meaning of this ABSTRACT
GEOCHEMICAL FEATURES, ISOTOPE COMPOSITIONS AND ENVIRONMENTAL IMPACTS OF HOT SPRINGS IN KEJIE FAULT AND CHANGNING-MENGLIAN STRUCTURAL BELT

To disclose the exact geochemical features of the hot springs in western Yunnan, China, this paper reviews the geological settings of Changning County, western Yunnan, and analyzes the geochemical features of local hot springs, which are controlled by Kejie Fault and Changning-Menglian (C-M) Structural Belt. On this basis, the author explored the isotopes of H, O, C, recharge source, recharge elevation circulation path and formation age of the geothermal flow, examined the main chemical process in the geothermal flow movement, especially in the mixing process, and determined the geochemical formation model and geological settings of the fault-controlled geothermal field in the research area. The results show that the hot springs are typical fault-controlled geothermal resources; the meteoric water is the main supply source of the hot springs; the hot springs are neither volcanic nor magmatic; despite the slight difference in activities and formation causes, the hot springs in both western and eastern parts of the research area were recharged by paleo-precipitation recharge before Late Pleistocene.
Tunable Fabry-Perot-Interferometer for 3-5 μm wavelength with bulk micromachined reflector carrier

This contribution deals with design, fabrication and test of a micromachined first order Fabry-Perot-Interferometer (FPI) usable as tunable infrared filter in a spectrometer. The approach discussed here minimizes mirror curvature by using relative thick (300 μm Si ) mirror carriers for the fixed and the movable mirror of the FPI. We use thermally grown λ/4 thick SiO2 for antireflection layer at the mirror back side and for the first low refractive layer followed by a λ/4 thick polycrystalline silicon high refractive layer. Second and third λ/4 layer pairs of SiO2 and polycrystalline silicon complete the mirrors. The cavity size is electrostically tuned and capacitively detected by a closed loop control.
Improving Energy Efficiency Through Automatic Refactoring

The ever-growing popularity of mobile phones has brought additional challenges to the software development lifecycle. Mobile applications ought to provide the same set of features as conventional software, with limited resources: such as limited processing capabilities, storage, screen and, not less important, power source. Although energy efficiency is a valuable requirement, developers often lack knowledge of best practices. In this paper, we propose a tool to improve the energy efficiency of Android applications using automatic refactoring — Leafactor. The tool features five energy code smells that tend to go unnoticed. In addition, we study whether automatic refactoring can aid developers to ship energy efficient mobile applications with a dataset of 140 free and open source apps. As a result, we detect and fix code smells in 45 Android apps, from which 40% have successfully merged our changes into the official repository.
The place of somatic embryogenesis in crop improvement through genetic transformation

Plant genetic transformation is an important biotechnological tool for the improvement of many crops and it relies on introducing genetic changes which can add beneficial characteristics or remove undesirable ones. This has become a high throughput platform for cultivar improvement in several crops as well as for studying gene functions in plants. The use of somatic embryogenesis as a means for the practical reality of plant genetic transformation in many crop plants is the focus of this review article.
A structural determinant of mycophenolic acid resistance in eukaryotic inosine 5′‐monophosphate dehydrogenases

Mycophenolic acid (MPA) is a potent natural product inhibitor of fungal and other eukaryotic inosine 5′‐monophosphate dehydrogenases (IMPDHs) originally isolated from spoiled corn silage. MPA is produced by the filamentous fungi Penicillium brevicompactum, which contains two IMPDHs, PbIMPDHA and PbIMPDHB, both of which are MPA‐resistant. The MPA binding sites of these enzymes are identical to MPA‐sensitive IMPDHs, so the structural determinants of resistance are unknown. Here we show that a single residue, Ser267, accounts for the MPA resistance of PbIMPDHA. Substitution of Ser267 with Ala, the residue most commonly found in this position in eukaryotic IMPDHs, makes PbIMPDHA sensitive to MPA. Conversely, Aspergillus nidulans IMPDH becomes MPA‐resistant when the analogous Ala residue is substituted with Ser. These substitutions have little effect on the catalytic cycles of either enzyme, suggesting the fitness costs are negligible despite the strong conservation of Ala at this position. Intriguingly, while only 1% of fungal IMPDHs contain Ser or Thr at position 267, these residues are found in the IMPDHs from several Aspergillus species that grow at the low temperatures also favored by Penicillium. Perhaps Ser/Thr267 is an evolutionary signature of MPA exposure.
Evaluation & Management of Functional Abdominal Pain in Children

Non-organic or functional, abdominal pain is pain that exists free of a pathologic state. This is the most common type of chronic abdominal pain in children. It interrupts a child’s normal daily activities and causes stress and anxiety amongst families. In the past, it has been poorly treated due to misconceptions and inadequate knowledge of evaluation and application of treatment. A proper history and physical evaluation of the abdominal pain is required for accurate diagnosis. ROME IV criteria is the diagnostic criteria used for children once organic chronic abdominal pain is ruled out. Treatments that are available for use in non-organic chronic abdominal pain in children consist of behavioral therapies, diet changes, and recently approved pharmaceutical medications.

We introduce the game of Surrounding Cops and Robber on a graph, as a variant of the traditional game of Cops and Robber. In contrast to the traditional game in which the cops win by occupying the same vertex as the robber, they now win by occupying each of the robber’s neighbouring vertices. We denote by σ(G) the surrounding copnumber of G, namely the least number of cops required to surround a robber in the graph G. We present a number of results regarding this parameter, including general bounds as well as exact values for several classes of graphs. Particular classes of interest include product graphs, graphs arising from combinatorial designs, and generalised Petersen
The upper frequency limit of dynamic cerebral autoregulation

Dynamic cerebral autoregulation (CA) is expressed by the temporal pattern of cerebral blood flow (CBF) recovery following a sudden change in arterial blood pressure (BP). Transfer function analysis of BP as input and CBF velocity as output can express dynamic CA through its amplitude (or gain) and phase frequency responses. The upper frequency limit (FupLim) at which dynamic CA can operate is of considerable physiological interest and can also provide additional information about worsening CA due to disease processes. In healthy subjects FupLim was strongly dependent on arterial PCO2 changes induced by four different breathing manoeuvres. The considerable intersubject variability in FupLim suggests that fixed frequency bands should not be adopted for averaging values of gain and phase in studies of dynamic CA.
Development of Instruments to Assess Shame and Guilt in Adolescents: Empirical Differences Between the Constructs

Shame and guilt are terms easily mixed in everyday life and often used as synonyms. Although they are words of similar use, they represent theoretically different moral emotions. The aims of this study were to develop and validate instruments to assess shame and guilt and to test the empirical independence of the constructs. Five hundred and eighty high school students from three Brazilian states participated in this study, 55% of them female, with an average age of 16.0 years. The participants answered a questionnaire containing socio demographic questions and scales designed for this study in order to assess shame and guilt. The scales developed gave appropriate evidence of validity and reliability. A single factor was extracted to assess shame and two factors to assess guilt (recognition of mistake and regret). The constructs revealed to be correlated, but independent. It is considered that there is sufficient evidence to affirm that shame and guilt are emotions with distinctive peculiarities and can be measured using the instruments developed in this research.
TITLE: Tumor Microenvironment and Progression to Invasion after a Diagnosis of Ductal Carcinoma In Situ

Randomized trials have demonstrated the efficacy of radiation and tamoxifen in reducing risk of second events after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS), but the comparative effectiveness of mastectomy, BCS, and adjuvant treatments have not been established in community practice. We examined disease-free survival (DFS) among 1,676 DCIS cases diagnosed during 1995–2006 in the population-based Wisconsin In Situ Cohort study. Information on patient and tumor characteristics, treatments, and second breast cancer events were collected via a comprehensive review of data from patient interviews, the statewide cancer registry, and pathology reports. Breast cancer DFS was evaluated according to treatment while adjusting for patient and tumor characteristics. After an average of 7.1 years of follow-up, 143 second breast cancer events occurred. Overall 5-year DFS was similar among women treated with ipsilateral mastectomy (95.6 %; 95 % CI 93.5–97.0) compared to women treated with BCS and radiation (94.8 %; 95 % CI 92.8–96.1), though women receiving BCS without radiation experienced poorer overall DFS (87.0 %; 95 % CI 80.6–91.5). Women treated with tamoxifen in addition to BCS and radiation had a similar risk of a second breast event, although the hazard ratio (HR) suggested a potential benefit (0.70, 95% CI 0.411.19). Women treated with BCS, radiation, and tamoxifen had comparable risk of a second event as those treated with ipsilateral mastectomy (HR = 1.20; 95 % CI 0.71–2.02). In this population-based sample, the use of BCS with radiation and tamoxifen resulted in high DFS rates comparable to those achieved by ipsilateral mastectomy.
4 2010 2 December Face Identification Algorithm using Two Dimensional Principal Component Analysis Based on Wavelet Transform

Face is the most common biometric used by humans, its applications range from static, mug-shot verification to a dynamic, uncontrolled face identification in a cluttered background. The main objective of this paper is to construct an effective human face identification system. The presented algorithm combines the scaling process, histogram equalization process, wavelet transform process, two dimensional principal component analysis (2DPCA) process, and support vector machine (SVM) methods to construct a human face identification algorithm. In the presented algorithm, the size normalized and histogram equalized human face images are divided into smaller sub-images by the wavelet transformation, the 2DPCA scheme is applied on LL sub-images to extract the features of human face image, and the SVM classifier is used to do the final identification. The experimental results show that the presented algorithm has good efficiency for human face identification.
An e-commerce facility location problem under uncertainty

Facility location problem is a branch of operational research and computational geometry. It involves the best allocation of facilities to minimize transportation costs, while considering factors such as avoiding placing dangerous materials near the premises and the facilities of competitors. According to B2C e-commerce unique customer characteristics and fierce market competition, two facility location models in e-commerce under uncertainty are proposed, i.e., expected value model and pessimistic value model. It is proved these models can be converted into equivalent models based on inverse uncertainty distribution method. A hybrid algorithm is proposed to solve these models. Some numerical experiments are used to demonstrate the effectiveness of the proposed models and approach.
Morphological variation of Ridged Frogs of the Taita Hills, Kenya

Comparing of morphological character variation within taxa continues to play an important role in improving species inventories. Using morphometrical and non-meristic morphological adult characters, the diversity of the genus Ptychadena in Taita Hills was studied. Comparative material from elsewhere was not used, and therefore species names were only provisionally allocated to the taxa identified. Avail- able names were discussed on the basis of comparisons with morphological data from other regions. The results revealed that female species are larger in size than males. Two species were identified and for each a standardized diagnosis of 32 characters is provided. Comparison of results with morphological data from related studies done elsewhere reveals that certain characters are of critical importance in differentiating the two Ptychadena species. The power of these morphological characters is discussed, especially for the background of rapid and easy identification of Ptychadena species in the field for conservation purposes.
Women's agricultural practices and their effects on soil nutrient content in the Nyalenda urban gardens of Kisumu, Kenya

Abstract. In Kisumu up to 60 % of the inhabitants practice some form of urban agriculture, with just under 50 % of the workers being female. On average, women spend more hours a day in the gardens than men. Therefore women's knowledge is pivotal for effective agricultural management. To enhance and better use women's knowledge, gender-related sociocultural obstacles linked to land ownership, investment, and farm inputs have to be taken into account. We aimed to determine how the agricultural knowledge and motivations of female farmers working in the Nyalenda urban gardens in Kisumu (Kenya) influence the soil nutrient status as reflected by the total soil C and N; available soil N and P; and exchangeable soil Na, K, Mg, and Ca. Two prevailing practices were compared to determine how the agricultural management practice influences soil nutrient content: (1) applying manure only and (2) applying manure while intercropping with cowpeas. Interviews and focus group discussions were held to explore the agricultural knowledge and motivations of the women working in Nyalenda. Soil analysis showed that the soil in Nyalenda was rich in nutrients overall but that the intercropped fields contained significantly lower total soil nutrients than fields where only manure was applied. While theoretically intercropping with a legume such as cowpeas should increase soil N content, due to socioeconomic factors, such as poverty, intercropping was applied in a way that did not increase soil nutrient contents; rather it diversified revenue. The knowledge of the female farmers was found to be limited to practical and sensory knowledge. This shows that when aiming to improve soil nutrient status and agricultural yields through agricultural training, socioeconomic conditions, cultural context, and gendered knowledge differentiation have to be acknowledged.
The receptor‐receptor interaction between mGluR1 receptor and NMDA receptor: a potential therapeutic target for protection against ischemic stroke

Ischemic stroke is one of the leading causes of long‐term disability worldwide. It arises when the blood flow to the brain is severely impaired, causing brain infarction. The current therapies for ischemic stroke are tissue plasminogen activator and mechanical thrombectomy, which re‐establishes blood circulation to the brain but offers no neuroprotective effects. Excitotoxicity, particularly through the N‐methyl‐D‐aspartate receptor (NMDAR), has been heavily implicated in the pathophysiology of brain infarction resulting from ischemic stroke. Here we investigated the interaction between NMDAR and metabotropic glutamate receptor 1 (mGluR1) as a novel target to develop potential neuroprotective agents for ischemic stroke. Through coimmunoprecipitation and affinity binding assay, we revealed that the interaction is mediated through 2 distinct sites on the mGluR1 C terminus. We then found that the disruption of mGluR1‐GluN2A subunit of NMDAR (GluN2A) protected the primary mouse hippocampal neurons against NMDAR‐mediated excitotoxicity and reversed the NMDAR‐mediated regulation of ERK1/2 in rat hippocampal slices. The same protection was also observed in an animal model of ischemic stroke, alleviating brain infarction and yielding better motor recovery. These findings confirmed the existence of a receptor‐receptor interaction between NMDAR and mGluR1, implicating this interconnection as a potential treatment target site for ischemic stroke. —Lai, T.

This study contributes towards the efficient design of biosensors based on 2D materials and DNA-coated upconversion nanoparticles.
Adenosine Depletion as A New Strategy to Decrease Glioblastoma Stem-Like Cells Aggressiveness

Glioblastoma is the brain tumor with the worst prognosis. This is mainly due to a cell subpopulation with an extremely aggressive potential, called glioblastoma stem-like cells (GSCs). These cells produce high levels of extracellular adenosine, which are increased even more under hypoxic conditions. Under hypoxia, adenosine signaling is related to HIF-2α expression, enhancing cell aggressiveness. Adenosine can be degraded using recombinant adenosine deaminase (ADA) to revert its pathological effects. The aim of this study was to degrade adenosine using ADA in order to decrease malignancy of GSCs. Adenosine depletion was performed using recombinant ADA. Migration and invasion were measured by transwell and matrigel-coated transwell assay, respectively. HIF-2α-dependent cell migration/invasion decreased in GSCs treated with ADA under hypoxia. MRPs-mediated chemoresistance and colony formation decreased in treatment with ADA. In conclusion, adenosine depletion using adenosine deaminase decreases GSCs aggressiveness.
The Proton Density of States in Confined Water (H2O)

The hydrogen density of states (DOS) in confined water has been probed by inelastic neutron scattering spectra in a wide range of its P–T phase diagram. The liquid–liquid transition and the dynamical crossover from the fragile (super-Arrhenius) to strong (Arrhenius) glass forming behavior have been studied, by taking into account the system polymorphism in both the liquid and amorphous solid phases. The interest is focused in the low energy region of the DOS (E<10 meV) and the data are discussed in terms of the energy landscape (local minima of the potential energy) approach. In this latest research, we consider a unit scale energy (EC) linked to the water local order governed by the hydrogen bonding (HB). All the measured spectra, scaled according to such energy, evidence a universal power law behavior with different exponents (γ) in the strong and fragile glass forming regions, respectively. In the first case, the DOS data obey the Debye squared-frequency law, whereas, in the second one, we obtain a value predicted in terms of the mode-coupling theory (MCT) (γ≃1.6).
