Tunable Bound States in the Continuum in All-Dielectric Terahertz Metasurfaces
Authors: Chen Xu , Fan Wenhui
Published: March 2020

In this paper, a tunable terahertz dielectric metasurfaces consisting of split gap bars in the unit cell is proposed and theoretically demonstrated, where the sharp high-quality Fano resonance can be achieved through excitation of quasi-bound states in the continuum (quasi-BIC) by breaking in-plane symmetry of the unit cell structure. With the structural asymmetry parameter decreasing and vanishing, the calculated eigenmodes spectra demonstrate the resonance changes from Fano to symmetry-protected BIC mode, and the radiative quality factors obey the inverse square law. Moreover, combining with graphene monolayer and strontium titanate materials, the quasi-BIC Fano resonance can be tuned independently, where the resonance amplitude can be tuned by adjusting the Fermi level of graphene and the resonance frequency can be tuned by controlling the temperature of strontium titanate materials. The proposed structure has numerous potential applications on tunable devices including modulators, switches, and sensors.

Authors: Oh Ji Soo , Oh Jong Sik , Yeom Geun Young
Published: March 2020

Silver nanowire (AgNW) has been studied as an important material for next-generation wearable devices due to its high flexibility, high electrical conductivity and high optical transmittance. However, the inherently high surface roughness of AgNWs and low adhesion to the substrate still need to be resolved for various device applications. In this study, an embedded two-dimensional (2D) Ag nanomesh was fabricated by mechanical press welding of AgNW networks with a three-dimensional (3D) fabric shape into a nanomesh shape, and by embedding the Ag nanomesh in a flexible substrate. The effect of the embedded AgNWs on the physical and electrical properties of a flexible transparent electrode was investigated. By forming embedded nanomesh-type AgNWs from AgNW networks, improvements in physical and electrical properties, such as a 43% decrease in haziness, 63% decrease in sheet resistance, and 26% increase in flexibility, as well as improved adhesion to the substrate and low surface roughness, were observed.

Published: March 2020

Bi(NO3)3·5H2O and (NH4)6Mo7O24·4H2O were used as precursors to synthesize flaky γ-Bi2MoO6 samples by a hydrothermal method, and Pt/γ-Bi2MoO6 samples with different mass fractions were prepared by an NaBH4 reduction method. Alpha alkylation of benzyl alcohol and acetophenone with photocatalysts under visible light irradiation was performed, and the activity of 4 wt % Pt/γ-Bi2MoO6 (γ-Bi2MoO6 was prepared by a nitric acid method, pH = 9, and reaction temperature 180 °C) was the best. The photocatalytic reaction conditions were optimized by changing various kinds of variables, such as the type of catalyst, solvent, and base, and the amount of base, catalyst, and reactant. The optimal conditions for the organic reaction were 75 mg 4 wt % Pt/γ-Bi2MoO6, 6 mL n-heptane, 1.2 mmol NaOH, 1 mmol acetophenone, and 3 mmol benzyl alcohol. Under the optimal reaction conditions, the effects of different light wavelengths and light intensities on the reaction were measured, and the cycling ability of the photocatalyst was tested. After five cycles, the photochemical properties of the catalyst were relatively stable. Finally, the active substances were identified (such as electrons (e−), holes (h+), hydroxyl radicals (•OH), and superoxide radicals (•O2−).

Published: March 2020

Adolescent pregnancy is an important public health issue, and pharmacist prescribing has the potential to expand contraceptive access and decrease unintended pregnancy. However, little is known about acceptability and uptake of pharmacist prescribing among adolescents, particularly among youth in socially and politically conservative regions of the country. The study objective was to identify how young women in Indiana perceive pharmacist contraceptive prescribing. Participants were recruited from clinics and completed a simulated pharmacist contraception-prescribing encounter; a demographic and behavioral questionnaire; and an in-depth qualitative interview focused on adolescent perspectives on pharmacist prescribing. Data were analyzed using thematic analysis. Sixty young women aged 14–21 years (mean age 17.0 ± 1.7 years) completed in-depth interviews. The majority expressed interest in pharmacist contraceptive prescribing (n = 33, 55.9%). Three overarching themes were identified, focusing on accessibility; quality of care; and pharmacist knowledge and youth friendliness. Subthemes highlighted the need for improved confidential access; a desire for additional pharmacist training in contraception; and interactions with a pharmacist that can relate to the young person. Increased awareness of the perceptions of young people can inform state policies and pharmacy protocols. Pharmacists, because of their accessibility, are well poised and equipped to assist in this public health concern.

Published: March 2020

Background: Therapy with oral anticoagulation (OAC) can be challenging, especially in high risk groups such as chronic patients. Gaps in patient knowledge about OAC are linked to reduced effectiveness and safety of treatment. The objectives of this study were i) to assess OAC knowledge gathered during an intermediate medication review (MR) in patients taking vitamin K antagonists (VKA) or non-vitamin K antagonist oral anticoagulants (NOAC); ii) to assess OAC knowledge two weeks after the MR, and iii) to evaluate patient satisfaction with the MR service in community pharmacies. Methods: Chronic OAC patients were invited for a regular MR service in Swiss community pharmacies, the so-called “Polymedication-Check” (PMC). OAC knowledge was assessed with seven newly generated items asked face-to-face during a PMC and by telephone two weeks later. Knowledge gaps, pharmacists’ spontaneous interventions, and patient satisfaction were documented by observing pharmacy students. Treatment groups were compared. Results: Of all patients (n = 81), the number of patients with one or more knowledge gaps decreased from 66% to 31.3% after PMC (p < 0.001). NOAC patients (n = 31) had more knowledge gaps than VKA patients (n = 50; p < 0.05). Most patients (98.6%) were satisfied with the counselling provided by the pharmacists. Conclusion: The majority of chronic OAC patients shows knowledge gaps. Although spontaneous, the provision of tailored education during a PMC increased patient OAC knowledge.

Published: March 2020

A continuing professional development (CPD) program for pharmacists practicing in community and team-based primary care settings was developed and evaluated using Moore’s framework for the assessment of continuing medical education. The program had three components: online lectures, a two-day training workshop, and patient case studies. Knowledge (pre-post multiple choice test); attitudes, readiness, and comfort with applying pharmacogenomics in their practices (pre-post surveys); and experiences of implementing pharmacogenomics in practice (semi-structured interviews) were assessed. Twenty-one of 26 enrolled pharmacists successfully completed the program, and were satisfied with their experience. Almost all achieved a score of 80% or higher on the post-training multiple choice test, with significantly improved scores compared to the pre-training test. Pre- and post-training surveys demonstrated that participants felt that their knowledge and competence increased upon completion of the training. In the follow-up, 15 pharmacists incorporated pharmacogenomics testing into care for 117 patients. Ten pharmacists participated in semi-structured interviews, reporting strong performance in the program, but some difficulty implementing new knowledge in their practices. This multi-component CPD program successfully increased pharmacists’ knowledge, readiness, and comfort in applying pharmacogenomics to patient care in the short-term, yet some pharmacists struggled to integrate this new service into their practices.
Systematic Medication Review in General Practice by an Interdisciplinary Team: A thorough but Laborious Method to Address Polypharmacy among Elderly Patients

Published: March 2020

Polypharmacy increases the risk of hospitalization but may be reduced by medication review. The study objective is to describe and evaluate a method for conducting medication review in general practice by an interdisciplinary medication team of pharmacists and physicians—in this case conducted by a team from the Department of Clinical Pharmacology—based on information concerning medication, diagnosis, relevant laboratory data and medical history supplied by the general practitioner. We discussed the medication review with the patients’ general practitioners and received feedback from them regarding acceptance rates of the recommended changes. Ninety-four patients with a total of 1471 prescriptions were included. A medication change was recommended for nearly half of the prescriptions (48%); at least one change of medication was recommended for all patients. The acceptance rate for recommended medication changes was 55%, corresponding to a mean of 4.2 accepted recommendations per patient. For 18% of all 1471 prescriptions, the general practitioner agreed either to discontinue (stop the medication completely) or reduce the dose of the medication. This method is thorough, but since it requires several healthcare professionals, it is rather time-consuming. There is a need to support medication review in general practice, but although this method may be too time consuming in most cases, it may nevertheless prove to be a useful tool managing the most complicated patients.
Disruptive Garb: Gender Production and Millennial Sikh Fashion Enterprises in Canada
Authors: Khamisa Zabeen
Published: March 2020

Several North American Sikh millennials are creating online values-based fashion enterprises that seek to encourage creative expression, self-determined representation, gender equality, and ethical purchasing, while steeped in the free market economy. Exploring the innovative ways young Sikhs of the diaspora express their values and moral positions in the socio-economic sphere, one finds many fashionistas, artists, and activists who are committed to making Sikh dress accessible and acceptable in the fashion industry. Referred to as “Sikh chic”, the five outwards signs of the Khalsa Sikh—the “5 ks”—are frequently used as central motifs for these businesses (Reddy 2016). At the same time, many young Sikh fashion entrepreneurs are designing these items referencing contemporary style and social trends, from zero-waste bamboo kangas to hipster stylized turbans. Young Sikh women are challenging mainstream representations of a masculine Sikh identity by creating designs dedicated to celebrating Khalsa Sikh females. Drawing on data collected through digital and in-person ethnographic research including one-on-one interviews, participant observation, and social media, as well as fashion magazines and newsprint, I explore the complexities of this phenomenon as demonstrated by two Canadian-based Sikh fashion brands, Kundan Paaras and TrendySingh, and one Canadian-based Sikh female artist, Jasmin Kaur.
Improved Strategies for the Maritime Industry to Target Vessels for Inspection and to Select Inspection Priority Areas
Authors: Knapp Sabine , Heij Christiaan
Published: March 2020

Inspection authorities such as the Port State Control Memoranda of Understanding use different policies and targeting methods to select vessels for inspections and rely primarily on past inspection outcomes. One of the main goals of inspections is to improve the safety quality of vessels and to reduce the probability of future incidents. This study shows there is room for improvement in targeting vessels for inspections and in determining vessel-specific inspection priority areas (e.g., bridge management versus machinery related items). For the year 2018, sixty percent of vessels that experienced very serious or serious (VSS) incidents were not selected for inspection up to three months prior to the incident and forty percent of the vessels that were inspected still had incidents of which only four percent were detained. Furthermore, one can observe a very low correlation (−0.04) between the probabilities of detention and incidents (VSS) for the year 2018. The proposed approach treats detention and incident types as separate risk dimensions and evaluates seven targeting methods against random selection of vessels using empirical data for 2018. The analysis is based on three comprehensive data sets that cover the world fleet and shows potential gains (reduction of false negative events) of 14–27 percent compared to random selection. This can be further improved by adding eight inspection priority risk areas that help inspectors to focus inspections by providing insight in the individual risk profile of vessels. Policy makers can further customize the approach by classifying the risk of vessels into categories and by selecting inspection targets and benchmark samples. A small application example is provided to demonstrate feasibility of the proposed approach for policy makers and inspection authorities.
Development of Topical/Transdermal Self-Emulsifying Drug Delivery Systems, Not as Simple as Expected
Authors: van Staden Daniélle , du Plessis Jeanetta , Viljoen Joe
Published: March 2020

Self-emulsifying drug delivery systems (SEDDSs) originated as an oral lipid-based drug delivery system with the sole purpose of improving delivery of highly lipophilic drugs. However, the revolutionary drug delivery possibilities presented by these uniquely simplified systems in terms of muco-adhesiveness and zeta-potential changing capacity lead the way forward to ground-breaking research. Contrarily, SEDDSs destined for topical/transdermal drug delivery have received limited attention. Therefore, this review is focused at utilising principles, established during development of oral SEDDSs, and tailoring them to fit evaluation strategies for an optimised topical/transdermal drug delivery vehicle. This includes a detailed discussion of how the authentic pseudo-ternary phase diagram is employed to predict phase behaviour to find the self-emulsification region most suitable for formulating topical/transdermal SEDDSs. Additionally, special attention is given to the manner of characterising oral SEDDSs compared to topical/transdermal SEDDSs, since absorption within the gastrointestinal tract and the multi-layered nature of the skin are two completely diverse drug delivery territories. Despite the advantages of the topical/transdermal drug administration route, certain challenges such as the relatively undiscovered field of skin metabolomics as well as the obstacles of choosing excipients wisely to establish skin penetration enhancement might prevail. Therefore, development of topical/transdermal SEDDSs might be more complicated than expected.
Are Danes’ Immigration Policy Preferences Based on Accurate Stereotypes?
Authors: Kirkegaard Emil O. W. , Carl Noah , Bjerrekær Julius D.
Published: March 2020

Stereotypes about 32 country-of-origin groups were measured using an online survey of the adult, non-elderly Danish population (n = 476 after quality control). Participants were asked to estimate each group’s net fiscal contribution in Denmark. These estimates were then compared to the actual net fiscal contributions for the 32 groups, taken from a report by the Danish Ministry of Finance. Stereotypes were found to be highly accurate, both at the aggregate level (r = 0.81) and at the individual level (median r = 0.62). Interestingly, participants over- rather than underestimated the net fiscal contributions of groups from countries with a higher percentage of Muslims. Indeed, this was true at both the aggregate and individual levels (r = −0.25 and median r = −0.49, respectively). Participants were also asked to say how many immigrants from each group should be admitted to Denmark. There was a very strong correlation between participants’ aggregate immigration policy preferences and their estimates of the 32 groups’ fiscal contributions (r = 0.98), suggesting that their preferences partly reflect accurate stereotypes. Most of the analyses were pre-registered.

Published: March 2020

This study contributes to the dissemination of the theoretical and empirical knowledge on the Upper Echelons Theory, considering training and demographic diversity in Top Management Teams (TMTs) as a unique feature of companies, in our case, the IBEX 35 companies. Based on the results, we can confirm that the inclusion of women in management teams positively influences the sales of a company and contributes to increasing financial results. Age and knowledge of two or more languages are important factors in achieving an increase in financial performance. From the point of view of business practice, the results obtained are useful for increasing knowledge of which TMT characteristics are valid, which allows for better results and the establishment of responsible organizational policies that promote the inclusion of gender diversity in TMTs. In addition, the results of this study indicate that the incorporation of members of other non-Spanish nationalities would constitute a distinctive feature of a company and would enrich it not only financially, but also culturally.

Published: March 2020

Recombinant measles AIK-C vaccine expressing the hemagglutinin (HA) protein of influenza A/Sapporo/107/2013(H1N1pdm) (MVAIK/PdmHA) was constructed. Measles particle agglutination (PA) and influenza hemagglutinin inhibition (HI) antibodies were induced in cotton rats immunized with MVAIK/PdmHA. Cotton rats immunized with two doses of the HA split vaccine were used as positive controls, and higher HI antibodies were detected 3 weeks after the first dose. Following the challenge of A/California/07/2009(H1N1pdm), higher viral loads (107 TCID50/g) were detected in the lung homogenates of cotton rats immunized with the empty vector (MVAIK) or control groups than those immunized with MVAIK/Pdm HA (103 TCID50/g) or the group immunized with HA split vaccine (105 TCID50/g). Histopathologically, destruction of the alveolar structure, swelling of broncho-epithelial cells, and thickening of the alveolar wall with infiltration of inflammatory cells and HA antigens were detected in lung tissues obtained from non-immunized rats and those immunized with the empty vector after the challenge, but not in those immunized with the HA spilt or MVAIK/PdmHA vaccine. Lower levels of IFN-α, IL-1β, and TNF-α mRNA, and higher levels of IFN-γ mRNA were found in the lung homogenates of the MVAIK/PdmHA group. Higher levels of IFN-γ mRNA were detected in spleen cell culture from the MVAIK/PdmHA group stimulated with UV-inactivated A/California/07/2009(H1N1pdm). In conclusion, the recombinant MVAIK vaccine expressing influenza HA protein induced protective immune responses in cotton rats.

Published: March 2020

Background: Hepatitis B still represents a health concern, although safe and effective vaccines have been available since 1982. Italy introduced a program of universal vaccination against hepatitis B in 1991. The aim of this study was to assess the immunity levels towards hepatitis B in a sample of sera from the pediatric and adolescent population in the province of Florence, Central Italy, twenty-seven years after the implementation of universal vaccination. Methods: A total of 165 sera samples were collected from the resident population of Florence aged 1–18 years. The anti-HBs and anti-HBc enzyme-linked immunosorbent Assay (ELISA) tests were performed on all samples. The anamnestic and vaccination status data were also collected. Results: Seroprevalence of anti-HBs was approximately 60%, with children aged 1–5 years having the highest positivity rate (81.6%), and decreasing trends in the older age groups. The zero prevalence of anti-HBc shows that the detected protective immunity is mainly due to vaccination, and natural infection was not reported in the studied population. Conclusions: The seroprevalence of anti-HBs and the lack of anti-HBc in this study highlights that immunity levels have been derived mainly from immunization. This confirms how vaccination dramatically reduced circulation of the hepatitis B virus in Italy in the pediatric and adolescent population twenty-seven years after implementation of the mandatory universal program.

Published: March 2020

Introduction. The process of predicting infrasound exposures in residential areas is difficult due to the lack of methods of mathematical modeling and calculating probable infrasound levels in an open area. The assessment of infrasound exposures in residential areas can be only performed using direct instrumental studies. The purpose of the study was to determine the prospects for organizing and monitoring infrasound exposures in residential areas. Materials and methods. We analyzed federal and departmental regulations on infrasound measurements. Low-frequency noise pollution in residential areas of various parts of St. Petersburg was studied. The objects of experimental research were selected in the immediate vicinity of road junctions, railways, air transport trajectories, and in the zones of large industrial enterprises. Results. More than 1,000 instrumental measurements were taken. We analyzed infrasound test reports, which were part of environmental engineering surveys, over a 10-year period and found significant discrepancies between the results obtained under similar conditions by various laboratories. Conclusions. We established that the infrasound levels produced by the main anthropogenic sources in St. Petersburg did not exceed permissible levels. We also substantiated inexpediency of conducting comprehensive studies and monitoring the parameters of infrasound in residential areas.

Hence, it can be concluded that the source of encouragement, technology facilities, and personal tendencies influence the students’ tendency to do business online.
Space-borne radar observation of near-surface wind effect on anomalously highly-directional backscattering of radio waves from Aeolian processes of sand and dust transporting in desert regions
Authors: Bychkov Dmitro , Ivanov Viktor , Matveyev Aleksandr , Tsymbal Valeriy , Yatsevich Sergey
Published: March 2020

Aeolian process of sand and dust transporting is known to form the near-ground surface structures over vast territories and fill the atmosphere up with suspended aerosols-like dust particles which are spread then by winds over long distances. The presence of atmospheric dust in the planet's environment is one of the factors affecting the temperature and climatic conditions of vast regions of the Earth. A number of publications (Ivanov et al., 2015; Ivanov et al., 2016; Ivanov et al., 2016; Ivanov et al., 2018) analyze the revealed effect of anomalously highly(narrow) directed backscattering of radio waves which manifests itself in radar remote sensing (in range of local irradiation angles θ ≈ 31°÷32°) in areas covered with deep sand. At the same time, there is no specific data available from published studies investigating the impact of the near-surface wind on anomalously highly-directional backscattering of radio waves based on the results of radar remote sensing researches of Aeolian sand and dust transport processes in desert regions that, in turn, could have been used later to determine the parameters of such transport process. This article presents the results of analysis of the data obtained from long-term studies of desert regions of El-Djuf, Akshar and Trarza in Mauritania by means of space-borne SAR Envisat-1. The purpose of the analysis was actually to identify the specifics of the effect that the near-surface wind has on the anomalously highly-directional backscattering of radio waves which is identified by radar based researches of Aeolian processes of sand and dust transport in desert regions, so can be used for remote determination of such transportation parameters.
Configurable Defected Ground Structures for Low Profile Antenna Performance Enhancement
Authors: Zhang Yujie , Han Zixiang , Shen Shanpu , Chiu Chi Yuk , Murch Ross
Published: March 2020

Versatile configurable defected ground structures

(CDGSs) for enhancing the performance of low profile antennas are introduced. It is shown that CDGS can significantly reduce mutual coupling (MC) between multiple antennas and suppress cross-polarization (XP) and enhance circular polarization (CP) excitation in single port low profile antennas for example. The key idea of CDGS is to construct defected ground structures (DGSs) from a grid of slots, which can be either opened or shorted with hardwires, so that they can be configured and optimized to enhance desired antenna performance characteristics. The

importance and versatility of the CDGS approach is that it

overcomes the issue of having to design bespoke DGS for each individual antenna design. Three design examples are provided to demonstrate the versatility of CDGSs for MC reduction, XP suppression and CP excitation. Experimental results demonstrate that MC can be reduced by up to 43 dB, XP can be suppressed by 15 dB and CP can be excited with 78 MHz (2.2%) 3-dB axial ratio (AR) bandwidth. The compactness and ease of fabrication also make the CDGS well suited to compact low profile internet of things (IoT) and wireless communication applications.

Social epistemology in information studies
Authors: Martínez-Ávila Daniel , Zandonade Tarcísio
Published: March 2020

The present paper aims to provide new details and information on the intellectual context in which social epistemology was born, including aspects such as its theoretical influences, intellectual contexts, and main characteristics. As methodology it presents an analysis of the writings on social epistemology by Jesse Shera and Margaret Egan selected from different and sometimes rare sources and collection. After an the analysis, the paper addresses the relationship between the historical social epistemology proposed by Margaret Egan and Jesse Shera as a discipline to investigate the foundations of librarianship and the contemporary social epistemology proposed by Steve Fuller as a program of a “naturalistic approach to the normative questions surrounding the organization of knowledge processes and products.” Both these proposals are outlined as an interdisciplinary project that is based on both philosophical epistemology and the scientific sociology of knowledge.

Published: March 2020

Soybeans are one of the most produced grains in the world, and because of the high cost of nitrogen fertilizers, new technologies in the inoculation of diazotrophic bacteria have been developed. The objective of this study was to evaluate the effect of Bradyrhizobium-based inoculant doses and Lipo-chito-oligosaccharide molecules (LCOs), together with bacterial protector as an additive, compared to a conventional inoculant in the inoculation of soybean seeds. The experiment was carried out in a greenhouse, with soil from a Red Oxissol of sandy texture. The experimental design was in randomized blocks with 3 replicates, the treatments being distributed in a 5 x 2 factorial scheme (2 inoculants and 5 inoculant doses). The seeds of the soybean cultivar M8866 were inoculated and seeded in the pots containing 11 L of substrate, where two plants remained for 45 days. Nine biometric-productive parameters were evaluated. Increasing the dose, regardless of the inoculant, provided an increase in root length and probably active nodules. In general, it was possible to observe statistical superiority of the inoculant with technologies integrated in relation to the conventional one, independent of the dose, when comparing the inoculants with respect to these two variables. Furthermore, the inoculant with integrated technologies provided a higher mass of fresh and dry matter of the nodules with the application of the highest inoculant dose (3.6 billion UFC mL-1). It was noted that increasing the dose of conventional inoculant did not cause the increase of fresh and dry matter mass of the nodules such as the inoculant with integrated technologies, suggesting the beneficial action of the bioprotectant and of the LCOs molecules.
Weed infestation and growth of cowpea in soil managed with solarization and mulching

Published: March 2020

The growth and production of agricultural crops are greatly hampered by weed interference. The objective of this study was to evaluate weed infestation and growth and dry mass of cowpea cultivated in soil with solarization and mulching. The research was carried in the Agricultural Sciences Center of the Federal University of Alagoas, Rio Largo, AL. A completely randomized experimental design was used, with eight treatments and four replications. The treatments consisted of the combination of soil with and without solarization together with different mulching, such as T1: Os tratamentos consistiram da combinação de solo com e sem solarização junto a diferentes coberturas mortas, como sendo T1: solarized soil with mulching of castor bean, T2: solarized soil with mulching of rattlepod, T3: solarized soil with mulching of spontaneous vegetation, T4: solarized soil without mulching, T5: non-solarised soil with mulching of castor bean, T6: non-solarised soil with mulching of rattlepod, T7: non-solarised soil with mulching of spontaneous vegetation and T8: non-solarised soil and without mulching. The number of weeds was higher in treatments without mulching, independent of solarization, T4 and T8. Already, the growth of the plants and the number of bean leaves were higher in the solarized soil with mulching of castor bean, T1, and lower in the non-solarized soil and without mulching, T8, in contrary to the dry mass of the root. Solarization with solar collector when associated with mulching inhibits the infestation of weeds in cowpea, while its growth is benefited by solarization + mulching, by mulching without solarization, as well as the solarization without mulching.

CSR gain local community development. However, its practice is contradictive, partially not only beneficial but also it does not bring significant benefits. CSR planning as an integration tool for the interest between corporate and local community is the main driving factor for its effectivity implementation. The article presents a communicative approach in CSR planning by combining both the concept of CSR and transactive planning. The general view that Corporate dominating CSR planning is the main criticism which causes its policy has not a significant impact. How is the conceptualization of CSR planning approach, which communicates with the beneficiary community, this article aims to reveal its understanding. The study evaluates the transactive process on CSR planning, through descriptive qualitative analysis of literature. The result proposes a CSR planning model based on transactive planning approach. The article also initiates that CSR planning is a transactive process which raised through knowledge transaction between planner and community toward towards legitimacy in increasing community support for company operations.
The geopolitical dimensions of the TurkStream pipeline
Authors: Smoleń Kinga
Published: March 2020

The empirical goal of this paper is to conduct an analysis of the geopolitical dimensions of the TurkStream pipeline, with special consideration given to its determinants as well as a diagnosis of the geopolitical implicationsof its geographical extent. To explore this problem, the following hypotheses are offered. First, the inauguration of the second branch of the TurkStream pipeline in the beginning of 2020 will strengthen the monopolistic positionof Russia as a supplier of natural gas to the countries of the European Union.This will increase the dependency of the EU on Russia and severely hamper itsability to formulate a unified, cohesive energy policy. Second, two factors that underlie the geopolitical importance of the TurkStream pipeline are Turkey’s and Southern Europe’s natural gas needs on the one hand and the political and economic interests of Russia, Turkey, and Ukraine on the other. Third, theTurkStream project should be seen as an instrument that serves to build a tactical partnership between Turkey and Russia – a partnership underpinned by the strategic interests of both countries in the Middle East. Fourth and finally, Russia’s gradual withdrawal from directing its natural gas through Ukraine will generate serious economic problems and potential energy shortages in that country. In the long term, this pressure is geared toward forcing Ukraine to re-evaluate the pro-Western trajectory of its foreign policy.

Objectives. Health care-related infections are a public health problem, among them surgical site infection (SSI) are the most frequent in hospitals. The objetive of this study was to assess the effect of the compliance to antibiotic prophylaxis protocol on the incidence of surgical site infection in hysterectomized patients.
Material and methods. A prospective cohort study was carried out between October 2009 and December 2018. The incidence of SSI was studied after a maximum period of 30 days from the moment of surgery. The degree of adequacy of antibiotic prophylaxis in hysterectomy and the effect of its inadequacy on the incidence of infection was evaluated using relative risk (RR) adjusted with a logistic regression model.
Results. A total of 1,025 interventions were studied in 1,022 women. The cumulative incidence of SSI was 2,1% (n = 22). The most frequent etiology of infection was Escherichia coli (23.1%) and Proteus mirabilis (23.1%). Antibiotic prophylaxis was indicated in 1,014 interventions (98.9%) being administered in 1,009 of them (99.5%). The adherence to the protocol was 92,5%. The main cause of non-compliance was the time of onset (40.9%), followed by the choice of the antibiotic (35.2%). The effect of inadequate prophylaxis on the incidence of infection was RR = 0.9; 95% CI 0.2-3.9; p> 0.05.
Conclusions. The adequacy of antibiotic prophylaxis was very high, with a low incidence of surgical site infection. No association was found between adequacy of prophylaxis and incidence of infection in hysterectomy. The continuous improvement of epidemiological surveillance in gynecology should be emphasized.
Presencia del Mediterráneo y Capri en la escritura de Neruda // The Presence of the Mediterranean and Capri in Neruda's Writing
Authors: Donoso Aceituno Arnaldo Enrique
Published: March 2020

En este artículo se analiza la presencia material del Mediterráneo y la Isla de Capri en un conjunto acotado de poemas y memorias del poeta chileno Pablo Neruda (1904-1973), a través de las nociones de territorio y agenciamiento, desarrolladas por Deleuze y Guattari en Mil mesetas. En el imaginario nerudiano, el Mediterráneo adquiere la categoría de espacio vital durante el periodo europeo de exilio político del poeta (1950-1952). La escritura exiliar de Neruda es una “escritura en movimiento” que a su paso agencia con los territorios y naturalezas mediterráneas. Nos interesa la escritura mediterránea producida en relación con la estadía de Pablo Neruda y Matilde Urrutia en Capri, en 1952, específicamente, los poemarios Los versos del Capitán (1952), Las uvas y el viento (1954), La barcarola (1967), y algunos fragmentos de las memorias Confieso que he vivido (1974) y Para nacer he nacido (1978). Abstract This article analyses the material presence of the Mediterranean and the Isle of Capri in a bounded set of poems and memoirs written by the Chilean poet Pablo Neruda (1904-1973), from the notions of territory and assemblage developed by Deleuze and Guattari in A Thousand Plateaus. In Nerudian imagery, the Mediterranean acquires the category of vital space during the poet’s period of political exile in Europe (1950-1952). Neruda’s writing during his exile is a “writing in movement” which assembles, in its path, with the Mediterranean territories and nature. We are concerned with the Mediterranean writing produced in relation to Pablo Neruda and Matilde Urrutia’s stay on Capri, in 1952, specifically the poem collections Los versos del Capitán (1952), Las uvas y el viento (1954), La barcarola (1967), and some excerpts from the memoirs Confieso que he vivido (1974) and Para nacer he nacido (1978).
Environmental Imaginations of the California Channel Islands and Ecological Crisis in T.C. Boyle's When the Killing's Done // Imaginaciones medioambientales de las Islas del Canal y la crisis ecológica en When the Killing’s Done
Authors: Leikam Susanne
Published: March 2020

This article explores T.C. Boyle’s thirteenth novel When the Killing’s Done (2011) in regard to its representation of ecological crisis and the ensuing environmental activism. In particular, it argues that the distinctly urban background and way of life of the two main protagonists, National Park Service staff member Alma Boyd Takesue and radical eco-hipster Dave LaJoy, foster environmental imaginations of the California Channel Islands that underestimate the centuries-long agricultural uses of the islands and romanticize the islands’ ecosystems as pristine ‘wilderness.’ While this perception in the tradition of the ‘American cult of wilderness’ prompts Alma and the National Park Service to reestablish a historical state of the islands’ ecosystems through the calculated extermination of invasive species, eco-activist Dave fiercely fights for the right of every non-human animal to live. Ultimately, the novel deconstructs both these endeavors to biodiversity and animal rights as highly flawed and environmentally as well as ethically inconsistent.   Resumen   Este artículo explora la decimotercera novela de T. C. Boyle con el título When the Killing’s Done (2011) en cuanto a la representación de la crisis ecológica y al consiguiente activismo ecologista. En particular, afirma que el fondo y la forma de vida claramente urbanos de los dos protagonistas principales, Alma Boyd Takesue, miembro del personal del Servicio de Parques Nacionales, y Dave LaJoy, un eco-hipster radical, fomentan imaginaciones medioambientales de las islas California Channel Islands que subestiman los largos siglos de uso agrícola de las islas e idealizan los ecosistemas de las islas como ‘naturaleza virgen.’ Mientras esta percepción en la tradición del “culto americano de naturaleza virgen” anima a Alma y al Servicio de Parques Nacionales a restablecer un estado histórico de los ecosistemas de las islas a través del exterminio deliberado de especies invasoras, el eco-activista Dave lucha decididamente por el derecho de todos los animales no-humanos a vivir. En última instancia, la novela deconstruye ambos esfuerzos por la biodiversidad y los derechos de los animales como muy imperfectos e inconsistentes tanto ambiental como éticamente.
Unpacking Business Model Innovation Through an Attention-Based View
Authors: Laszczuk Alexis , Mayer Julie C.
Published: March 2020

Attention is considered as a critical driver for business model (BM) innovation in established firms, where existing activities already absorb internal actors’ time and effort. Although previous studies acknowledge the role of attention to detect opportunities or to generate new ideas, we still need to understand how actors deal with attentional tensions inherent in the development of a new additive BM. This article addresses this issue by adopting an attention-based view of BM innovation, that is, by examining the forms of attention involved in the process of developing a new BM. Through a longitudinal study in a small consulting company, we unfold an incremental and ongoing process of new BM development. Our findings identify three attentional stages triggered by specific mechanisms that drive BM innovation, from detecting new ideas to their implementation. The attentional perspective we use in this study revises the role of a prevailing BM in the emergence of new business logics in established firms. While previous studies consider it as an impediment for BM innovation, we reveal that actors can develop new BMs by navigating between differentiation and consistency with the prevailing BM.
