A modified method for calibration of polarimetric components using polarizing interferometry

Polarization interferometer technique has been developed for calibration of phase retardation elements such as quarter/half wave plate with known tolerance in each one. In addition, this technique is used to measure unknown retardation elements to identify its phase retardation. A polarizing beam splitter is placed after Sagnac interferometer to split the produced fringes into p and s polarization interferograms to be analyzed. The phase retardation measurements depend on two states, the reference state which includes recording the reference p and s interferogram images without placing the sample then measuring state at which the p and s interferogram images are recorded after placing the sample inside Sagnac interferometer. Six images are recorded for each interferogram under a controlled environment to calculate the repeatability of measurements and for uncertainty estimation. The detected images are mathematically processed to determine the phase retardation of the polarimetric components. The results are found to be in a good consequent with the data measured by Senarmont compensator method.

Purpose – Using an enhanced version of the theory of reasoned action (TRA), this study investigates the antecedents of organic quinoa-based food buying intention. In addition to attitude toward this behavioral intention, the proposed model examines the influence that ecological welfare, political values, and consumerperceived corporate social responsibility (CSR) of the point of sale exert on consumer willingness to purchase organic quinoa-based food. Design/methodology/approach – Structural equation modeling (SEM) was used to analyze the data collected through an intercept survey conducted at specialized organic stores on a convenience sample of 158 individuals in Italy. Findings – Although ecological welfare and a retailer’s CSR image positively influence consumer attitude toward buying organic quinoa-based food, political values negatively affect this attitude. Furthermore, consumer attitude is found to be a crucial predictor of behavioral intention. Research implications – At the theoretical level, the results are useful for demonstrating that other variables, in addition to those used in the traditional TRA, can further explain consumers’ organic food buying intention. Additionally, the findings might be useful for both quinoa producers and retailers in creating and executing their marketing and communication strategies. Originality/value – In addition to contributing to the stream of literature that investigates possible variables that might increase the predictive power of the TRA, this study sheds some light on organic food purchasing consumer behavior.

ARTIFICIAL BANDWIDTH EXTENSION USING A GLOTTAL EXCITATION MODEL

The historical bandwidth of telephone speech (0.3 kHz to 3.4 kHz), which is still used today for speech transmission (e.g. in the AMR-codec [1]) leads to reduced intelligibility and naturalness of the transmitted speech. New mobile devices may use artificial bandwidth extension (ABE) to improve the received narrow-band (NB) speech quality. Aiming to reconstruct missing frequency components of NB speech on the receiving end, ABE often adopts the sourcefilter-model of human speech to reconstruct excitation and spectral envelope of the speech signal separately. In the extension of the excitation, no existing method exploits the fact that the wide-band (WB) excitation for vowel sounds can be modeled by parametric functions with nearly no perceptible differences [2]. This work investigated the possibility to extract optimal model parameters from the NB speech to use them for high quality ABE of the excitation for vowels. The proposed algorithm objectively meets or exceeds a state-of-the-art reference algorithm, but is currently subjectively slightly inferior.
Attitudes of Academic Staff from Different Stages of Their Proficiency in Research and Teaching Activities in Sports Sciences: A Case Study of the University of Montenegro

The goal of this research was the identification of differences between academic staff in sports sciences based on their proficiency from early-career researchers to experts related to different academic activities. A survey of professors from the University of Montenegro from different stages of their proficiency was conducted. Data collection included two standardized tools: 1) a questionnaire (N=23 respondents) and 2) interviews (N=6 respondents) about different academic activities, such as writing, researching, teaching, and learning. The results obtained revealed a lack of formal writing training as a barrier in academic writing, as well as other activities, including workloads (e.g., teaching, administration (54.6%)) and lack of time generally (45.5%) for early-career researchers. In the context of teaching support, early-career researchers confirmed a higher position to develop teaching competencies compared with expert teachers. Generally, the results showed that centralized support for teachers at this institution exists more for research than teaching activities at all career stages, which was expected according to standards and conditions for career progress. The theoretical and practical implications of results are discussed.
TNFa-Induced Mucin 4 Expression Elicits Trastuzumab Resistance in HER2-Positive Breast Cancer

Purpose: Although trastuzumab administration improved the outcome of HER2-positive breast cancer patients, resistance events hamper its clinical benefits. We demonstrated that TNFa stimulation in vitro induces trastuzumab resistance in HER2positive breast cancer cell lines. Here, we explored themechanism of TNFa-induced trastuzumab resistance and the therapeutic strategies to overcome it. Experimental Design: Trastuzumab-sensitive breast cancer cells, genetically engineered to stably overexpress TNFa, and de novo trastuzumab-resistant tumors, were used to evaluate trastuzumab response and TNFa-blocking antibodies effectiveness respectively. Immunohistochemistry and antibody-dependent cell cytotoxicity (ADCC), together with siRNA strategy, were used to explore TNFa influence on the expression and function of its downstream target, mucin 4 (MUC4). The clinical relevance of MUC4 expression was studied in a cohort of 78 HER2-positive breast cancer patients treated with adjuvant trastuzumab. Results: TNFa overexpression turned trastuzumab-sensitive cells and tumors into resistant ones. Histopathologic findings revealed mucin foci in TNFa-producing tumors. TNFa induced upregulation of MUC4 that reduced trastuzumab binding to its epitope and impaired ADCC. Silencing MUC4 enhanced trastuzumab binding, increased ADCC, and overcame trastuzumab and trastuzumab-emtansine antiproliferative effects in TNFa-overexpressing cells. Accordingly, administration of TNFa-blocking antibodies downregulated MUC4 and sensitized de novo trastuzumab-resistant breast cancer cells and tumors to trastuzumab. In HER2-positive breast cancer samples, MUC4 expression was found tobe an independent predictor of poor disease-free survival (P 1⁄4 0.008). Conclusions: We identified TNFa-induced MUC4 expression as a novel trastuzumab resistancemechanism.We proposeMUC4 expression as a predictive biomarker of trastuzumab efficacy and a guide to combination therapy of TNFa-blocking antibodies with trastuzumab. Clin Cancer Res; 23(3); 636–48. 2016 AACR.
Exploring Fruit Tree Species as Multifunctional Greenery: A Case of Its Distribution in Indonesian Cities

Planting multifunctional trees (e.g., fruit species) in cities can promote genetic conservation, economic activity, ecosystem services, and social cohesion. However, in Indonesia, the relationship between the abundance of fruit tree species and different city characteristics, including their involvement in the national smart city project, is still unknown. In this study, published reports and field surveys were used to evaluate the fruit tree distribution and its relationship with the characteristics of 224 of 514 Indonesian cities in order to identify tree species for multifunctional city greenery. This is the first study on the distribution of fruit tree species at the national level. The study identified 151 fruit species of 90 genera and 40 families, including large-sized fruits, such as avocados, breadfruit, coconuts, durians, jackfruit, and mangos. On average, cities contained 54 tree species, of which 21 (38.9%) were fruit trees. These findings indicate that cities are important contributors to the genetic conservation of local fruit trees, which can be further evaluated as new city greenery. However, a city’s involvement in the smart city project bore no relationship (p > 0.05) with the number of identified fruit species. Conversely, non-fruit species tended to be more diverse in smart cities. Since the presence of fruit species is associated with the city population, geographic position, climate, altitude, and attitude towards the fragility of sustainable conservation, introducing and maintaining these species as city greenery requires advocacy to city stakeholders.
STUDY OF THE INHIBITORY EFFECT OF SALIX ACMOPHYLLA BOISS LEAF AND BARK EXTRACT ON (E. COLI) BACTERIA

This study was done to investigate the effect of secondary metabolites in willow bark and leaf extracts of “Salix Acmophylla Boiss” in its raw form and its effect on one of the bacteria’s types that infect the external venereal areas of females, the study proceeded to prepare two types of extracts: aqueous and alcoholic extracts of willow leaves and bark. This study showed the existence of different compounds included (glycosides, phenols, alkaloids, carbohydrates, soaps, flavonoids, and titanates), as these active compounds were detected for the extracts by using the preliminary detectors. The effectiveness of the raw extracts on E. Coli bacteria was tested and the experiment was repeated three times, and the results showed a clear significant inhibitory effect of the extracts, which differed according to the concentration, and the best of them was willow bark extract. The toxicity test of the extracts was also studied and it was found that the aqueous bark was free of toxicity, while the aqueous and alcoholic willow leaf and the alcoholic bark were toxic with varying degrees.
Evaluation of an online training for healthcare workers on the health information management system (HIMS) for screening of Non-Communicable Diseases (NCD)

Background: Rapid rise in non-communicable diseases (NCD) has become a major public health challenge in Sri Lanka. Healthy lifestyle centers (HLCs) were established in 2011 for screening of NCDs and risk factors with majority of them functioning at primary care institutions. A web based HIMS-HLC module was developed to gather screening data from HLCs. Objective of the study was to assess the post-training status of the Healthcare workers (HCW) conducting HLCs trained on HLC-HIMS module in Sri Lanka. Materials and Methods: A descriptive cross-sectional study was carried out in June 2021 among 119 HCW attached to the HLC trained on HLC-HIMS module selected using simple random sampling. The questionnaire was formulated based on Kirkpatrick model covering four domains i.e., reaction, learning, behaviour and result. Data were collected by using a pre-tested self-administered questionnaire by the means of a google form shared via online platforms; e mail and WhatsApp and Viber after obtaining informed written consent. Data were analyzed by using descriptive statistics and associations were determined by using chi square test. Results: The response rate was 87.3% (n=104). Mean age 40.4 years (SD = 8.0 years) with majority in 36-50 years group (52.9%, n=55), Of participants, females 73.1% (n=76), nursing officers 70.2% (n=73) good computer literacy 61.5% (n=64). Only one third had overall good knowledge (37.5%, n=39) regarding the HIMS-HLC module. However, 74.0% (n=77) had favourable reactions, 78.8% (n=82) had favourable behaviour and 83.7% (n=87) had favourable results following HIMS training. Younger age and good computer literacy were significantly (P<0.05) associated with favourable reactions, behaviour and results. Conclusion: HIMS training has given favourable outcomes in majority of the participants especially in reaction, behavior and results following training. The concept of e-training can be adopted for the in-service training of HCW including those working at PHC level to combat the difficulties in conducting physical trainings during a pandemic. A special emphasis should be added for participant’s age and computer literacy when such trainings are designed.

Parageneses and Crystal Chemistry of Arsenic Minerals

The labyrinthine world of arsenic minerals has piqued the curiosity of many researchers in mineralogy, geochemistry, chemistry, and environmental sciences. Arsenic was known to the ancient civilizations; there are written Greek, Roman, and Chinese reports about minerals and substances of this element (Emsley 2001). The discovery of elemental arsenic is attributed to Albertus Magnus (1193–1280) who prepared it by reduction of As2O3. The common public association of arsenic and poison is the heritage of a long history of eliminating unwanted and unloved ones with compounds of this element. Mary Ann Cotton (1832–1873) was charged with murder of her mother, three husbands, a lover, eight of her own children, and seven stepchildren, all of them with an arsenic-based de-worming compound (Emsley 2005). Kořinek (1675) gave a vivid and frightening account on how a natural ferric sulfo-arsenate (bukovskýite) was used to poison the German armies of Albrecht Habsburg who invaded Bohemia in 1304. An arsenic derivative called lewisite (2-chlorovinyl-dichloroarsine) was used in the World War I (Emsley 2001). On the other hand, brightly-colored arsenic compounds were used in all imaginable products well into the 20th century. Arsenic whetted the appetite of many children as green arsenical chemicals were used as cake decorations and coatings of sugar sweets (Emsley 2005). The death of Napoleon Bonaparte has been regarded for a long time as a consequence of ingested or inhaled arsenical compouds (e.g., Aldersey-Williams 2011), however there are alternative interpretations (Lugli et al. 2011). Accidental mass arsenic poisoning occurred in Manchester in 1900 when many men drank beer contaminated with arsenic. The arsenic was tracked back to pyrite which was used to produce sulfuric acid which was employed in the manufacture of glucose for this batch of beer (Emsley 2005). Despite its toxicity, arsenic finds a few uses in …
weak-topology on certain group algebras

We investigate possible preduals of the measure algebra M(G) of a locally compact group and the Fourier algebra A(G) of a separable compact group. Both of these algebras are canonically dual spaces and the canonical preduals make the multiplication separately weak∗-continuous so that these algebras are dual Banach algebras. In this paper we find additional conditions under which the preduals C0(G) of M(G) and C ∗(G) of A(G) are uniquely determined. In both cases we consider a natural coassociative multiplication and show that the canonical predual gives rise to the unique weak∗-topology making both the multiplication separately weak∗-continuous and the coassociative multiplication weak∗-continuous. In particular, dual cohomological properties of these algebras are well defined with this additional structure.

Purpose – Given the importance of immigration and immigrant entrepreneurs in advanced economies, the authors take an entrepreneurial ecosystem perspective to study the home-country benefits possessed by immigrant entrepreneurs and how home-country entrepreneurial ecosystem factors affect immigrant entrepreneurial motivations, activities and outcomes. Design/methodology/approach – This conceptual research paper follows McGaghie, Bordage and Shea’s (2001) four-step new theory creation process, which suggests that new theories can be created through facts extraction from the extant literature. Findings – The authors propose that although immigrant entrepreneurs are unable to take full benefit of the host-country entrepreneurial ecosystem due to blocked mobility, they do have capabilities to access and use their home-country entrepreneurial resources and opportunities. The authors further propose that homecountry entrepreneurial capital can be systemically analyzed through the framework of the entrepreneurial ecosystem. The results imply that immigrant entrepreneurship as a social and economic phenomenon can be studied more holistically from both hostand home-country perspectives compared to the traditional research boundary of the host-country only. Research limitations/implications –The research focuses on the identification of home-country effects on immigrant entrepreneurship through the lens of the entrepreneurial ecosystem. Testable propositions provide directions for future empirical research on the field of immigrant entrepreneurship from a home-country perspective. The research concludes that a holistic immigrant entrepreneurship study should consider dual (hostand home-country) entrepreneurial ecosystems. Practical implications – Immigrant entrepreneurs benefit from both hostand home-country entrepreneurial ecosystems. This paper suggests co-effects of dual entrepreneurial ecosystems lead to a high rate of entrepreneurship and business success within some immigrant groups. Policymakers can increase economic activities by developing and deploying programs to encourage immigrants to embed in hostand home-country entrepreneurial ecosystems. Originality/value – Based on the framework of the entrepreneurial ecosystem, this paper brings a novel perspective to examining home-country effects on immigrant entrepreneurship. It theoretically conceptualizes that immigrants have higher entrepreneurship rates than native-born populations because they have access to extra home-country entrepreneurial capital.
Report of 22 unrecorded bacterial species in Korea belonging to phylum Bacteroidetes, discovered during surveys in 2018

The phylum Bacteroidetes was first proposed by Krieg et al. (2012) to accommodate phenotypically diverse groups of Gram negative rods that do not form endospores, and currently includes 6 classes, 6 orders, 33 families and 380 genera as of August 2019 (Euzéby, 2019). Bacteroidetes encompasses aerobic and anaerobic heterotrophs, hydrogen utilizing chemolithotrophs and methylotrophs, and some members are capable of nitrogen fixation. Their habitats are also diverse, including terrestrial and aquatic environments, environments with extreme physicochemical conditions, and animal and plant hosts. There have been reports of unrecorded species of this phylum in Korea, and recent studies indicate that members of the genera Chryseobacterium, Flavobacterium, Mucilaginibacter, and Pedobacter have been recovered as main taxa (Cho et al., 2018; Lee et al., 2018; Maeng et al., 2018). In a series of extensive surveys on the prokaryotic diversity in Korea in the year 2018, novel strains belonging to the phylum Bacteroidetes were isolated from various environmental sources, and their taxonomic properties were analyzed. As a result, a total of 22 unrecorded species of Bacteroidetes were identified, and their taxonomic properties are presented. Journal of Species Research 9(1):26-34, 2020
Mobile Pedestrian Navigation Framework for Multi-factors Resources Allocation

Although it is possible for pedestrian to walk to unfamiliar places, familiarizing and finding a way out of new environments is quite challenging unless a pedestrian navigation system (PNS) is used. Most existing PNS solutions are employing vehicle navigation framework, however, such systems are designed to work efficiently for vehicular systems and not suitable for finding shortest path in environment with poor geospatial mapping. This study designed pedestrian navigation framework for PNS that supports resource allocations in environment with poor geospatial mapping. Mixtures of qualitative and quantitative methods have been used to interview prospective users for requirement specifications and experimental research for designing the framework, respectively. Prototyped route network framework with routing data were implemented using Open source QGIS software, and a route analysis achieved using QGIS shortest path network analysis. The resulted framework shows more than 3.5% improvement between optimal routes established by PNS on proposed framework as compared to optimal route established by existing systems.

Stimulating Root Regeneration of Landscape-Size Red Oak With Auxin Root Sprays

Sprays of 3000 ppm indole-3-butyric acid (IBA) and napthaleneacetic acid (NAA), applied to freshly cut roots of 250-300 cm tall red oaks (Quercus rubra L) dug by tree spade, increased the number of roots regenerated from medium (5-1 5 mm) and large (15-25 mm) diameter roots. IBA stimulated more new roots than NAA on large roots only. As root diameter increased there was a trend to more regenerated roots. The root spray method may be more practical than others recommended and may be commercially feasible.
