Internal market orientation adoption and new service development (NSD): gearing up the internal performance of NSD teams

Purpose This paper reports on the impact of perceived resource adequacy (PRA) and competence (PRC) on new service development (NSD) teams’ internal performance (IP). This study aims to explore the indirect effect of internal market orientation (IMO) adoption, as a dynamic capability, on both PRA and PRC through the shaping of the emerging dynamics within NSD teams. Design/methodology/approach Using a hierarchical research design, the authors use a meso-theory approach to test a path-analytic framework against 116 NSD managers (offering data at the macro- or organisational level) and 543 NSD team members (offering data at the micro- or team level). Findings Both PRA and PRC are important in explaining NSD teams’ IP at the organisational level, though their explanatory power varies. The adoption of IMO is also an important antecedent to this factor through the (indirect) effect on the team climate and degree of integration. Research limitations/implications IMO is an important dynamic capability that allows management to transform the mindset of employees, even if they do not directly interact with customers. In NSD efforts, this reflects on the team’s perceptions of the adequacy of the resources they have to deliver the project through the managerial interventions at the team level, which (mainly) explains the team’s IP. Practical implications Adopting an IMO allows the development of a dynamic capability that carries wider benefits for the service organisation, as this has positive implications not just for frontline employees. Specifically, NSD efforts are likely to become more resource-efficient as a result of IMO adoption because of the interventions of management during the development effort. Originality/value This empirical study is the first to test the impact of IMO adoption as a dynamic capability and in a context other than frontline employees from a meso-theory perspective. This allows considering the different effects at the appropriate levels (macro and micro), thus enabling a more accurate definition of the mechanism through which companies benefit from IMO adoption.
The use of molecular techniques to resolve relationships among traditional weaving cultivars of Phormium

Abstract Molecular techniques ‐ sequencing of the nuclear internal transcribed spacer region (ITS), and fingerprinting of amplified fragment length polymorphisms (AFLP) and intersimple sequence repeats (ISSR) ‐ were investigated for their potential to characterise genetic variation in harakeke (Phormium spp., family Hemerocallidaceae) in New Zealand. ITS showed no variation between species of Phormium. However, both AFLP and ISSR identified genome regions that were polymorphic among intraspecific accessions of Phormium obtained from the National New Zealand Flax Collection. When used as a direct sequencing marker, one AFLP fragment distinguished two major groups of nuclear haplotypes. The partitioning of taxa into these groups was supported by phylogenetic analysis of ISSR fingerprinting profiles. Split decomposition, a network‐building technique, was shown to be useful in representing the sorts of relationships present in this study of intraspecific variation. Further sampling of natural populations is required to understand the origins and present‐day distributions of these accessions; however, the present results show the usefulness of these methods for addressing such ethnobotanic questions.
Application of Horticultural and Tissue Culture Methods for Ex Situ Conservation of Endangered Primula farinosa L.

Our study aimed at active conservation of the last location of Primula farinosa, an endangered species in Poland, and assessed reproduction by seeds and plant propagation on sterile media in tissue culture conditions. We identified gibberellic acid (GA3) as the key factor stimulating germination of P. farinosa seeds. Growing juvenile plants under controlled temperature of 18/16 °C day/night yielded good quality plant material without mycorrhization. In tissue culture, the most favorable medium for shoot propagation was MS supplemented with the lowest tested concentration of indole-3-butyric acid (IBA; 0.05 mg dm−3) and 6-benzyl-aminopurine (BAP; 0.1 mg dm−3). The rooting ability of shoots was high and comparable for all auxins used. 2C DNA content of seed-derived and micropropagated plants did not indicate any change in the ploidy level during in vitro cultivation. Plants derived from seeds and tissue cultures were compared in a 2-year study. Of all the characteristics compared, only the number of flowers per inflorescence was lower for micropropagated plants when compared with the seed-origin plants in the first year of observation. The difference was of transient nature and was not observed in the second year of the study. Effective protocols for in vivo and in vitro propagation of P. farinosa were developed, which can be used in practical species protection.
Sum-Rate Maximization for UAV-Assisted Visible Light Communications Using NOMA: Swarm Intelligence Meets Machine Learning

As the integration of unmanned aerial vehicles (UAVs) into visible light communications (VLCs) can offer many benefits for massive-connectivity applications and services in 5G and beyond, this article considers a UAV-assisted VLC using nonorthogonal multiple-access. More specifically, we formulate a joint problem of power allocation and UAV’s placement to maximize the sum rate of all users, subject to constraints on power allocation, quality of service of users, and UAV’s position. Since the problem is nonconvex and NP-hard in general, it is difficult to be solved optimally. Moreover, the problem is not easy to be solved by conventional approaches, e.g., coordinate descent algorithms, due to channel modeling in VLC. Therefore, we propose using the Harris hawks optimization (HHO) algorithm to solve the formulated problem and obtain an efficient solution. We then use the HHO algorithm together with artificial neural networks to propose a design that can be used in real-time applications and avoid falling into the “local minima” trap in conventional trainers. Numerical results are provided to verify the effectiveness of the proposed algorithm and further demonstrate that the proposed algorithm/HHO trainer is superior to several alternative schemes and existing metaheuristic algorithms.
SISAR imaging for space debris based on nanosatellites

The increasing amount of space debris poses a growing challenge in the development of space travel. In previous work, a proposed system comprising of a low budget space-borne passive radar based on CubeSAT, flying in Low Earth Orbit (LEO), demonstrated promising results in terms of space debris detection performance. In this work, a novel shadow inverse synthetic aperture radar (SISAR) model for space debris imaging based on nanosatellite is presented. An analysis of the received forward scattering signal is provided along with a novel model for moving transmitters and receivers SISAR imaging. Using simulated data and assuming different scenarios, the performance of the new algorithm is assessed; wherein, a classification scheme is applied using the output of the SISAR algorithm for classification between simple target shapes.
Atomic Carbon Spraying: Direct Growth of Graphene on Customized 3D Surfaces of Ultrafast Optical Devices

Despite the long‐standing efforts to develop 3D graphene, which is critical for practical electronic, optoelectronic, and optical devices, the lack of synthetic methods and the use of conventional transfer approaches have limited its realization. Herein, a metal‐free, etching‐free, transfer‐free, direct synthesis of functional graphene is introduced that contours 3D‐structured surfaces of nonlinear optical devices, thereby maximizing the nonlinear interaction of graphene with guided light. Central to this method is the use of γ‐Al2O3, a ceramic catalyst, which generates carbon atoms from the precursor molecules and supplies them for the graphene synthesis on the 3D structures located near the catalyst through spatial diffusion, described as atomic carbon spraying (ACS). The optical nonlinearity facilitated by ACS‐processed 3D graphene is experimentally verified by realizing both passively mode‐locked laser with a pulse width of 770 fs and ultrafast optical switching with 67% enhancement in nonlinear effect over 6 mm interaction length.
Rate, Indications and Fetal Outcome of Cesarean Section Deliveries at a University Hospital in Cairo

Background & Objective(s): Cesarean section (CS) rates increased in different parts of the world. Egypt demographic and Health Survey report (2014) shows that Egypt is the third country worldwide. Caesarean sections are associated with shortand long-term complications. The aim of this study was to measure rate and trend of CS at Ain Shams Maternity Hospital (2011-2015), to identify characteristics of females who delivered by CS during the last two years of the study duration (2014-2015) and to find out risk factors of unfavorable/poor fetal outcome. Methods: A descriptive observational study by record review was performed by randomly selecting 1305 files from hospital archives of 2014 and 2015. Results: Rate of CS increased over 5 years (20112015) from 27.6% to 36.9. CS rate was 36.6% in 2014 and 36.9% in 2015. The majority of cesarean deliveries (80%) were due to maternal causes (out of which 63% were due to previous CS). Half of the fetal causes was due to fetal distress. Multivariate logistic regression revealed that preterm birth (<37 weeks) and maternal health problems necessitating CS, significantly determined fetal outcome. Conclusion: The rate of CS in this study was higher than that recommended by international guidelines. Preterm birth and maternal indications for CS significantly determined fetal outcome. Evidence-based protocols for deliveries should be adopted or updated if present and to have clear criteria as well as a written policy for when a CS should be performed.
Separation of μ-Opioid Receptor Desensitization and Internalization: Endogenous Receptors in Primary Neuronal Cultures

A close relationship between desensitization and internalization of μ-opioid receptors (MORs) has been proposed based on differential actions of series of agonists. The role that these two processes have in the development of tolerance and dependence to opioids has been a controversial subject that has been studied in a variety of model systems. Here, we examine desensitization and internalization of endogenous MORs simultaneously in primary cultures of locus ceruleus neurons using fluorescently tagged peptide agonists. With the use of two fluorescent opioid peptides, dermorphin-Bodipy Texas Red and dermorphin-Alexa594 (Derm-A594), desensitization was measured electrophysiologically and trafficking was followed by the accumulation of intracellular fluorescent puncta. Blocking endocytosis with concanavalin A eliminated the accumulation of fluorescent puncta but desensitization induced by Derm-A594 was unaffected. Likewise, after treatment with concanavalin A, there was no change in either desensitization or recovery from desensitization induced by [Met]5enkephalin. The results demonstrate that desensitization and the recovery from desensitization are not dependent on receptor internalization and suggest that the activity of endogenous MORs in primary neurons can be modulated at the level of the plasma membrane.
Corporate governance and business innovation among listed Moroccan companies

Purpose This paper aims to clarify the relationship between corporate governance (GOV) and business innovation (INOV). Does it provide the empirical evidence of how different GOV mechanisms affect INOV within listed Moroccan companies? Design/methodology/approach The paper opted for a confirmatory quantitative study using a closed-ended questionnaire using a fifth-degree Likert scale. The questionnaire was administered to 54 listed Moroccan firms represented by their senior management having mainly a finance and economics background. Findings The paper provides empirical insights and evidence about how mechanisms of GOV impact INOV within listed Moroccan companies. It suggests that effective mechanisms of GOV foster and incubate INOV. Research limitations/implications There have been very empirical studies that investigate the relationship between GOV and innovation. As such, the authors’ conceptual framework relies more on the theoretical aspect of this subject than empirical one. Therefore, researchers are encouraged to test the proposed propositions further. Originality/value A review of the few existing empirical studies shows mitigated results regarding the relation between GOV and innovation. The findings of this study show a significant positive relation between GOV and its mechanisms and INOV.
SHORT-TERM FORECASTING OF BELEXLINE AND BELEX15 MOVEMENTS

At the onset of 2019, global economy has been facing a number of macroeconomic issues, which significantly multiplied in the course of the past ten-year period. Slow-moving rate of economic growth, increased fiscal deficits, enormous public and private debt – these are just some of the issues which led to the plunge of the leading stock market indices at the end of 2018. Bearing in mind that S&P 500, DJIA and NASDAQ Composite stopped the multiannual growth trend which started on March 22, 2009, new quakes on the global financial market may well be expected. Unlike developed global stock markets, which hugely recovered from the 2008 crash, the Belgrade Stock Exchange showed no significant growth trend in the observed period. In this respect, regardless of the detected declines of the world’s best known stock market indices, it is not realistic to expect any significant change in the Belgrade Stock Exchange share market, which the conducted empirical research should confirm. The basic goal of the research is to establish the monthly tendencies of BELEXline and BELEX15 movements in the forthcoming one-year period. The basic hypothesis of the research is that there will be no significant changes in the movement of the values of selected stock market indicators in the Belgrade Stock Exchange share market during the one-year period to come.
Characteristics of Radiation of a round Waveguide through a Flat Homogeneous Heat Shield

The problem of obtaining an analytical description of the radiation characteristics of a circular waveguide closed by a flat homogeneous dielectric plate is solved. The radiation characteristics include: the radiation field; the conductivity of the aperture radiation; and the fields of surface, flowing, and side waves, as well as energy characteristics. In such a statement, a strict solution of Maxwell ’ s equations is required. The paper uses the method of integral transformations and the method of eigenfunctions. In this case, the assumption is used that the electrical parameters of the dielectric plate (thermal protection) and the geometric dimensions do not depend on time. The relations describing the directional diagram of a circular waveguide with dielectric thermal protection and taking into account the electrical parameters of thermal protection and its thickness are obtained. Expressions are also obtained for the fields of lateral, surface, and outflow waves, from which it is possible to calculate the power taken away by these fields. Numerical calculations were made for some of the obtained relations. The results showed that the power of the side waves is zero. It also follows from the calculations that the radiation field of surface and flowing waves is absent, that is, their contribution to the directional diagram is not.
First-line immune-chemotherapy combination for squamous NSCLC is already a reality

© Translational Lung Cancer Research. All rights reserved. Immune checkpoint inhibitors (ICI) have improved the prognosis and redefined the treatment strategy of metastatic non-small cell lung cancer (NSCLC) patients. In the firstline setting, ICI have become standard of care (SoC) either as monotherapy (pembrolizumab for tumours with high programmed cell death ligand-1 (PD-L1) expression (≥50%) in Europe or with PD-L1 ≥1% in the United States of America) (1-3) regardless of histologic subtype, or in combination with chemotherapy regardless of PD-L1 expression in non-squamous (pembrolizumab/atezolizumab plus platinum-doublet chemotherapy, or atezolizumabcarboplatin-paclitaxel-bevacizumab) (4-7). In contrast to non-squamous histology where personalised treatment approaches along with ICI have improved the outcome (2,4,8), survival improvements in squamous NSCLC have been quite limited or without any meaningful clinical impact so far (9). However, based on the KEYNOTE-407 trial, the introduction of ICI in the first-line treatment of metastatic squamous NSCLC has marked a step forward in the therapeutic strategy of this patient population, improving both the outcome (1,2,10) and quality of life (11,12). The phase III, placebo-controlled, KEYNOTE-407 trial assessed the progression free survival (PFS), assessed by independent radiological review, and overall survival (OS) benefit of adding pembrolizumab to carboplatin plus (nab)-paclitaxel in 559 treatment-naive metastatic squamous NSCLC patients. In case of no disease progression after four cycles of the combination strategy, maintenance treatment either with pembrolizumab or placebo was administered for up to 35 cycles. Stratification factors included PD-L1 expression (≥1% versus <1%), choice of taxane (paclitaxel versus nab-paclitaxel) and geographic region (East Asia versus rest of the world). Of note, crossover was allowed: 32% of patients in the control arm received an ICI at the time of progression, whereas for those who discontinued treatment for any reason the crossover percentage reached 43%. Baseline characteristics were well balanced between the two groups (median age 65 years, approximately 80% male, approximately 2/3 Eastern Cooperative Oncology Group Performance Status (ECOG PS) 1, majority current or former smoker, approximately 2/3 PD-L1 expression ≥1%). Pembrolizumab compared to placebo significantly improved both co-primary endpoints: the OS (15.9 versus 11.3 months (HR 0.64, 95% CI: 0.49–0.85, P<0.001) and the PFS (6.4 versus 4.8 months, HR 0.56, 95% CI: 0.45–0.70, P<0.001) (10). In a secondary interim analysis, after a median follow-up of 14.3 months, the OS benefit with pembrolizumab was maintained (17.1 versus Editorial Commentary
ANALYSIS OF PARTICLE DISTRIBUTION IN A DOUBLE LAYER BEAM SHAPING ASSEMBLY RESULTED FROM 30 MEV-PROTON REACTIONS WITH BERYLLIUM TARGET USING THE PHITS PROGRAM

An analysis on the distribution of particle flux emanating from reactions of 30 MeV-proton with beryllium target in a double layer beam shaping assembly (BSA) has been carried out using the PHITS program. It studies important parameters relating to the distribution of proton, neutron, and gamma. It is revealed that reactions of proton and beryllium in double layer BSA produce fast neutrons and other protons, resulting from certain reactions, and recoil protons from the interactions of fast neutrons and hydrogen atoms. Fast neutrons are distributed around beryllium target, moderator, reflector, and collimator. They are moderated by Al and LiF material. Epithermal neutrons spread along the moderator, with a distribution that is tapering down as it approaches the end of the collimator (aperture). During its travel along the moderator, an epithermal neutron decreases in energy to become a thermal neutron. The spectrum of neutron beam produced by the double layer BSA is wide, which indicates that the neutron beam exiting the aperture consists of three kinds of neutrons, dominated by epithermal neutrons with energy range 1 eV – 10 keV.
The Inclusionary Populist Communication Style on Facebook: The Case of Ada Colau in Barcelona

Communication is one of the core elements of populism, especially in social media. Through such digital platforms, political leaders can communicate directly with citizens and build both their discourse and their political leadership. Although the literature has so far identified the existence of a populist political communication style, the expansion of populism and its connection with social media are extending and diversifying the concept, as well as adding new repertoires. In order to analyse this, we propose a study of the communication strategy of the mayor of Barcelona, Ada Colau who, with a background of citizen activism, became mayor of the city in 2015 thanks to a political organisation situated as left populist. The methodology is based on quantitative and qualitative analysis of the content of Colau’s Facebook profile. A total of 226 posts between 2015 and 2017 are analysed. The results make it possible to identify a new specific modality within the populist style of political communication, namely the inclusionary populist type. This focuses on issues related to defense of the rights of the weakest social groups and works within a framework of social justice and solidarity with others. Likewise, the study confirms how Facebook is configured as a preferred platform for the construction of political leadership.

The application and utility of DNA relatedness to bacterial taxonomy are discussed in order to stimulate greater awareness and use of this technique. Applications include: (i) the recognition of new taxa; (ii) the identification of grossly atypical strains in a taxon; (iii) the classification of poorly studied groups of organisms; and (iv) changes in existing classifications. Also discussed are the identification and differentiation of bacteria in the clinical laboratory. Guidelines for the molecular definition of species are presented.
Recent advances on hybrid integration of 2D materials on integrated optics platforms

Abstract The burgeoning research into two-dimensional (2D) materials opens a door to novel photonic and optoelectronic devices utilizing their fascinating electronic and photonic properties in thin-layered architectures. The hybrid integration of 2D materials onto integrated optics platforms thus becomes a potential solution to tackle the bottlenecks of traditional optoelectronic devices. In this paper, we present the recent advances of hybrid integration of a wide range of 2D materials on integrated optics platforms for developing high-performance photodetectors, modulators, lasers, and nonlinear optics. Such hybrid integration enables fully functional on-chip devices to be readily accessible researchers and technology developers, becoming a potential candidate for next-generation photonics and optoelectronics industries.
