Authors: Tajpour Mehdi , Salamzadeh Aidin , Salamzadeh Yashar , Braga Vitor 
Published: July 2021

PurposeThe purpose of this paper is to investigate social capital's effect on family business development in selected family media firms.Design/methodology/approachThe statistical population includes 100 individuals who run a family business in this industry. Eighty individuals are selected as the research sample through the stratified random sampling method. The data are collected using a questionnaire. The authors used structural equation modelling method for data analysis.FindingsThe results indicate that social capital affects the development of family businesses in media firms. According to the results obtained from the structural equation test, the effect of the relational dimension of social capital on trust and the effect of the cognitive and structural dimensions of social capital on trust are supported, while the effect of the relational dimension of social capital on commitment as well as the effect of the cognitive dimension of social capital on trust are not supported.Practical implicationsThis research could help family firms in media industries improve trust and commitment by paying attention to different aspects of social capital. Besides, it shows that even the impact of relational and cognitive social capital, respectively, on commitment and trust, are not supported; these two could affect trust and commitment, respectively.Originality/valueThe paper is among the first studies that investigate family firms in media industries. Besides, the relationships between relational, cognitive and structural aspects of social capital and trust and commitment are rarely studied in the literature as two determinants of family business development.

It's our museum too: co-producing research in a university museum through a nursery residency programme
Authors: Noble Kate , Wallis Nicola 
Published: July 2021

PurposeThe authors draw on Howard and Thomas-Hughes' (2020) framework for quality assessment of co-produced research, to interrogate our assumptions and processes and to reflect on our project. They consider if they achieved our planned outcomes around developing practice, enabling a range of voices and perspectives within their research, and enacting change within the university museum.Design/methodology/approachThe authors’ early years residency programme explores the potential of collaborations with community groups to transform knowledge and practice through action research. As museum educators, the authors find synergy between the participatory pedagogies underpinning their practice and the co-construction of knowledge within action research. Both are committed to enabling diverse interpretations within a collective and supportive framework. Within their project, practitioners from the museum and playgroup worked collaboratively to collect video footage, photos, children's artwork and reflective journals and memos.FindingsThe process of action, observation and reflection revealed much about the authors’ different perspectives and they found variations in both pedagogy and practice. Although the authors had a shared commitment to providing high quality, memorable, exciting opportunities for the children, the exploratory nature of the project meant that they did not agree what these experiences might look like in advance, and so they had different understandings of what they saw.Research limitations/implicationsAlthough the authors’ methodological framework was designed to make their research collaborative, structural challenges and the contexts of the art museum and university reinforced long established hierarchies. While some felt supported by the research process and the prestige of working with a university museum to gain legitimacy for their practice, others were disempowered by these same structures. The authors consider their obligations as practitioner-researchers to become aware of the role they play in maintaining, as well as challenging, hierarchies and assumptions.Originality/valueYoung children in museums is a growing area of study and this practitioner-led action research project develop a new strand of enquiry within this field. Through this research the authors can collaborate with community partners to record, analyse and make visible the many different ways in which young children experience the museum. As research led institutions, university museums are ideally placed to develop research in partnership with local public bodies and community groups. However, future work in this area would benefit from a more explicit consideration of the constraints implicit within the institutions within which they all operate.
Structural and electrical study of BLT thin film deposited on different substrates by electron gun evaporation
Authors: Abdallah B. , Nasrallah F. , Tabbky W. 
Published: July 2021

Purpose
The purpose of this study was to deposit Bi4Ti3O12 films by electron gun evaporation technique starting from Bi3.25La0.75Ti3O12 as a target without annealing. The films have been deposited on Si(100), on thin film buffer layer of Pt and glass substrates. X-ray diffraction (XRD) was used to analyze structure of the films, which possesses a good structure with (0010) preferred orientation. Electronic behavior of the samples has been studied.

Design/methodology/approach
The dependence of both the structure and quality of the BLT thin films on different substrates is studied using XRD. The electrical characteristics were determined using capacitance–voltage (C–V) and current–voltage (I–V) measurements at the frequency of 1 MHz. Optical properties of the grown films deposited on glass substrates were characterized by optical transmittance measurements (UV-Vis).

Findings
The XRD analysis approved the crystallographer structure of the prepared Bi4Ti3O12 films. The optical properties of deposited film (transmittance and the band gap value) are extracted by UV-Vis spectrum.

Originality/value
High crystalline quality Bi4Ti3O12 films have been obtained using different substrates at room temperature by means of electron gun deposition. The electrical and ferroelectric properties of thin films were studied using I–V and C–V measurements. The band gap has been found to be about 3.62 eV for the studied film deposited on glass substrate. Electron beam evaporation technique is the most interesting methods, once considering many advantages; such as its stability, reproducibility, high deposition rate and the compositions of the films are controlled.

AbstractA 52‐year‐old man underwent pneumonectomy of the left lung for previously diagnosed primary spindle cell carcinoma (pT4aN1M0, stage III B) with programmed death‐ligand 1 expression (tumor proportion score ≥95%) and without epidermal growth factor receptor gene mutation and anaplastic lymphoma kinase fusion gene. However, brain metastasis and chest wall tumor relapse occurred. Considering insufficient improvement with gamma knife treatment for brain metastasis and combination chemotherapy (paclitaxel, carboplatin, and bevacizumab), pembrolizumab monotherapy and palliative irradiation therapy for chest metastases were started after brain tumor volume reduction using craniotomy. Brain edema and chest wall metastases markedly improved following a pseudoprogression of the brain edema accompanied by a performance status decline; this effect continued until 11 cycles of pembrolizumab administration.
Three methods to measure parasite aggregation using examples from Australian fish parasites
Authors: Lester Robert J. G. , Blomberg Simone Phillipa 
Published: July 2021

Abstract

The distribution of parasites in host populations is integral to simulations of parasite populations.

We compared three methods to measure parasite aggregation, namely the Hoover, coefficient of variation and I10 indices, using field data from a range of fish parasites. These included anisakid nematodes, trypanorhynch cestodes and polyopisthocotylean monogeneans from 10 previously published studies and one unpublished study.

Positive correlations among the three methods were high. Standard errors and estimated biases obtained by bootstrap methods were smallest for the Hoover index. There was no evidence for a bias–variance trade‐off.

The analyses suggest that the Hoover index is to be preferred as a measure of aggregation although difficulties remain in deriving theoretical and operational definitions of aggregation.
Oestrogen receptors: A potential therapeutic target in oesophageal adenocarcinoma?
Authors: Due Steven L. , Watson David I. , Hussey Damian J. 
Published: July 2021

AbstractOesophageal cancer is the seventh most common cancer in the world and adenocarcinoma is the dominant subtype in Western industrialised nations. The global 5‐year relative survival rate for oesophageal adenocarcinoma is 12%. Chemotherapy is a standard treatment offered to patients with both resectable and unresectable disease. However, there are only a few established chemotherapeutic drug options and progress in this area is limited. Recent efforts have focused on targeted molecular therapies. Epidemiological evidence points towards hormonal influences on disease development, particularly sex hormones. Several research studies have demonstrated oestrogen receptor (ER) expression in oesophageal adenocarcinoma tissue, making them a possible option for targeting with ER modulating agents. ERs are also present in laboratory models of the disease and experiments in ER‐positive cell lines suggest that ER modulator therapy may be effective. A deeper understanding of the roles of ERα and ERβ in this disease would be valuable for future translation into clinical practice. In this review, we discuss the association between oestrogens and the development of oesophageal adenocarcinoma and the potential to modulate ER signalling networks for therapeutic benefit.
Analytical investigation of the original painted canvas of Santa Irene, by Giuseppe Verrio (Church of Sant'Irene, Lecce, Italy)*
Authors: Rizzo Daniela , Casciaro Raffaele 
Published: July 2021

AbstractThe object of this study is unusual for both its material and technique. It is an oil painting on sheets of paper glued to a canvas made of linen fibres, thereby showing some execution peculiarities. It depicts the Virgin of Thessalonica in a hieratic attitude. The painting is attributed to the Salento‐born artist Giuseppe Verrio (1639) for the church of the Theatine religious Order in Lecce, Italy, in which it is still placed, on the left altar of the transept. To truly understand and appreciate a work of art, it is important to have a basic knowledge of the materials and techniques used by the artist. For a better understanding of the execution techniques and to study the original materials and those that have been added over time, the painting was examined using the following analytical techniques: microscopic examination of cross‐sections, μ‐Raman spectroscopy and pyrolysis gas chromatography‐mass spectrometry (Py‐GC‐MS). The data indicate that Verrio used different earthy, mineral and manufactured pigments, an organic dye used only on the paper, oil as a binder, and varnish as a protectant. The results demonstrate that the latter are both original and due to a subsequent restoration.
How harmful are cuts in public employment and wage in times of high unemployment?
Authors: Betti Thierry , Coudert Thomas 
Published: July 2021

AbstractSince 2010, and in line with austerity measures, public employment and public‐sector compensations to employees have been significantly reduced in most Euro Area member states and particularly in Spain and Greece. At the same time, unemployment in these two economies was greatly increasing. In a dynamic and stochastic general equilibrium (DSGE) model, we demonstrate that these cuts in public employment and wages are more damaging in terms of output and employment losses in periods of high unemployment. The model is able to produce significant state dependence of fiscal multipliers. Main results can be summarized as follows: (1) Public‐sector wages shocks produce larger multipliers than public‐sector employment shocks; (2) with a higher steady‐state unemployment, response of non‐Ricardian consumption to fiscal shocks are worse while Ricardian households consumption is better off, thanks to lower inflation following fiscal shocks and a higher marginal utility of consumption at the high‐unemployment steady state; (3) a larger share of non‐Ricardian households, a higher job separation rate, and a lower matching efficiency amplify fiscal multipliers; (4) a passive monetary policy increases fiscal multipliers in the case of public vacancy shocks but dampens multipliers associated with cuts in public‐sector wages; and (5) fiscal multipliers are larger when demand and supply shocks hit the economy, to a greater extent in the case of a negative shock on aggregate demand.
Enhancing dye adsorption of wool by controlled and facile surface modification using sodium bisulphite

Published: July 2021

AbstractWool is a natural biopolymer with special properties, including warmth retention and skin‐friendliness. However, its application in the textile industry is limited by the scale layer that covers its surface, which prevents the efficient diffusion of dye into the interior of its fibres, and increases wool's susceptibility to shrinkage during washing. Here, dissolution with sodium bisulphite is used for wool surface modification. The properties of surface dissolved wool are comprehensively characterised, including strength loss, shrinkage rate and dyeability. The three‐dimensional images indicated that scale layer was etched. Coupled with Fourier‐transform infrared (FTIR) spectra, the test results of strength loss and shrinkage rate indicated that surface dissolution degree can be controlled by time and temperature, and that the process does not break the fibre's main body structure. Dyeability properties, including dye absorption rate, deepness and uniformity at a lower temperature were enhanced, indicating amenability to industrial production. Our findings highlight a novel, efficient method of modifying protein fibre surface for enhancing properties with potential for large‐scale application.

Published: July 2021

AbstractAimsPatients with heart failure (HF) and with diabetes experienced significantly worse outcomes than those without diabetes. However, data on the prognostic impact of prediabetes in HF are inconclusive. This meta‐analysis aimed to explore the association between prediabetes and the risk of all‐cause mortality and adverse cardiac outcomes in patients with HF.Materials and methodsWe searched multiple electronic databases (PubMed, Embase and Google Scholar) for relevant studies up to 31 March 2021. Studies were included for analysis if multivariable adjusted relative risks of adverse outcomes were reported in patients with prediabetes and with HF compared with those with normoglycaemia. Random‐effects models were used to calculate the pooled hazard ratios (HRs) and 95% confidence intervals (CIs).ResultsTwelve studies comprising 28 643 patients with HF reported the risk of all‐cause mortality and cardiac outcomes associated with prediabetes. The prevalence of prediabetes ranged from 9.6% to 37.2%. After a median follow‐up duration of 2.3 years, patients with HF and with prediabetes were associated with an increased risk of all‐cause mortality (HR 1.29, 95% CI 1.06‐1.58), cardiovascular mortality (HR 1.59, 95% CI 1.09‐2.32), HF hospitalization (HR 1.33, 95% CI 1.09‐1.61), all‐cause mortality and/or HF hospitalization (HR 1.22, 95% CI 1.01‐1.47), as well as cardiovascular mortality and/or HF hospitalization (HR 1.21, 95% CI 1.07‐1.37).ConclusionsPrediabetes is associated with a worse prognosis in patients with HF. Further risk stratification and effective treatment strategies are needed in patients with prediabetes and with HF to improve the prognosis.

Published: July 2021

AbstractBackgroundAdolescence describes the age group between 10 and 19 years. This is the transitional stage of physical and physiological human development generally occurring between puberty and adulthood. Hormonal changes occurring during puberty result in various physical and psychological changes, affecting their social relationship. At this stage, external appearance is of immense concern to them. As such, any dermatological condition can extremely affect their psychological status. This study was conducted to give an insight on the various dermatological conditions of the adolescent age groups and their incidence.MethodsStudy design: Descriptive study – Cross‐sectional study. Three hundred patients between the ages of 10 and 19 years, attending the tertiary care center in South India, were included in the study. A detailed history, clinical examination, and appropriate laboratory investigations were carried out.ResultsOut of 300 patients, females (52.7%) more commonly presented with dermatoses than males (47.3%). Most of the 300 patients belonged to the age group of 17–19 years (50.33%). Infections/infestations (39%) were the most predominant dermatoses followed by acne (17.67%), eczema (9.67%), insect bite reactions (IBRs) (7%), keratinization disorders (6.67%), polymorphic light eruptions (PLEs) (4.33%), urticaria (4.33%), and pigmentary disorders (4.33%).ConclusionThis study gives an insight of various dermatological conditions among the adolescent age groups. Females more commonly presented with dermatoses. The most common dermatoses were infections. Since very few studies regarding dermatoses in adolescents are available in the literature, this study is distinctive in this regard.

AbstractPrevious evidence suggests that sialic acid‐binding Ig‐like lectin 7 (Siglec‐7) protein is significantly increased in patients with chronic hepatitis C virus (HCV) infection and directly correlates with clinical parameters of liver inflammation and fibrosis. The aim of this study was to determine the diagnostic value of Siglec‐7 as a non‐invasive tool to assess liver fibrosis in patients with chronic hepatitis C in a cross‐sectional study. Serum levels of Siglec‐7 were retrospectively tested in 1007 consecutive patients with chronic HCV infection recruited at three different European sites and data examined by the ‘imperfect gold‐standard’ statistical analysis. Liver stiffness obtained by transient elastography (TE) was considered the standard reference. Liver fibrosis was staged according to published cut‐offs of liver stiffness measurement by TE. Accuracy of detection of liver fibrosis stage was not increased by Siglec‐7 alone. However, we developed a new index (SiGAP) including Siglec‐7, γ‐glutamyl transferase, age and platelet count which showed increased sensitivity and specificity in predicting fibrosis compared with APRI or FIB4 indices. The AUROC of SiGAP for the diagnosis of significant (≥F2) and advanced liver fibrosis (≥F3) showed significantly higher values than those of APRI and FIB‐4. Siglec‐7 may be useful as a complementary tool to assess liver fibrosis stage in patients with chronic hepatitis C when included in a specifically designed algorithm, which showed high level of accuracy in the detection of F2 and F3 fibrosis stage.

AbstractSeveral studies have showed that combining peg‐interferon alpha (Peg‐IFNα) with nucleotide analogues has complementary effects in chronic hepatitis B (CHB), but the optimal regimen and potential mechanisms remain unclear. This was a prospective, longitudinal and multicentre clinical trial (NCT03013556). HBeAg‐positive CHB naïve patients were randomly assigned to three groups: tenofovir disoproxil fumarate (TDF) monotherapy for 96 weeks, TDF alone for 48 weeks and sequentially Peg‐IFNα added for 48 weeks, TDF de novo combination with Peg‐IFNα for 48 weeks then TDF alone for 48 weeks. The primary endpoint was HBeAg seroconversion at week 96 and HBsAg loss as the secondary endpoint. Furthermore, the levels of 12 cytokines in serum were assessed at different time points. A total of 133 patients were included in the analysis. The rates of HBeAg seroconversion at 96 weeks were not significant different among the three groups (p = 0.157). Interestingly, patients in the Peg‐IFNα add‐on group showed markedly lower HBsAg level compared with the other two groups at week 96. In addition, only three patients in the Peg‐IFNα add‐on group achieved HBsAg loss. For the following 24 weeks from week 96, no HBsAg reappearance in the three patients and no new patients with HBsAg loss were observed in the three groups. Serum cytokine analysis showed that the baseline level of interferon‐inducible protein‐10 (IP‐10) was strongly higher in HBeAg conversion patients and HBsAg loss patients. Compared with de novo combination and TDF alone, the addition of Peg‐IFNα in TDF‐treated group might be an effective strategy for HBsAg loss in HBeAg‐positive CHB naïve patients.
