Employer Review Platforms – Do the Rating Environment and Platform Design affect the Informativeness of Reviews? Theory, Evidence, and SuggestionsDate submitted: December 29, 2019Date accepted after double-blind review: December 2, 2020
Authors: Cloos Janis
Published: October 2021

Online employer review platforms (ERPs) enable employees to evaluate their current and former companies anonymously online. Job-seekers can use the aggregated reviews to obtain information about potentially attractive companies and thus limit the number of suitable companies. However, the matching process between job-seekers and companies can only be effective if the information provided on ERPs is representative and can be trusted. This paper investigates specific characteristics of ERPs using the two large ERPs Kununu and Glassdoor as examples. It is argued that the ERP environment is very different from the well-known and -studied reputation system environment of online marketplaces, and that specific factors can potentially bias reviews on ERPs. Based on a new data set containing the Kununu and Glassdoor reviews of 114 major German employers, it is analyzed if and how design aspects of ERPs and other specific factors affect reviews. Results show that overall (and industry-specific), average review scores on Kununu and Glassdoor differ significantly from each other. Further results indicate that factors such as employees’ awareness of their impact on a company’s reputation also affect reviews. Suggestions are made on how ERPs could reduce the influence of these factors in order to present the aggregated information more effectively.
Disentangling performance outcomes of a firm’s innovativeness: A resource-advantage perspective
Authors: Miočević Dario , Talaja Anita , Alfirević Nikša
Published: October 2021

Inconsistent findings from the literature suggest that the relationship between innovativeness and performance is more complex than it might be presumed. By drawing on the resource-advantage theory, in this study we investigate: 1) the moderating effect of buyer power and competitive rivalry, and 2) the mediating role of customer- and competitor-based positional advantage on the relationship between innovativeness and sales-based and profit-based performance. The findings from the survey on 132 medium- and large-sized industrial firms in Croatia show that buyer power and competitive rivalry positively moderate the relationship between innovativeness and performance outcomes. Moreover, it was found that customer- and competitor-focused positional advantages mediate the link between innovativeness and performance outcomes. The findings of this study contribute to the literature and management practice by shedding new light on the nature of innovativeness in industrial firms.
HR Management and Perceived Effectiveness of Further Education and Training Methods of Millennial Employees in the Czech Republic
Authors: Mikova Irena , Komarkova Lenka , Pudil Pavel , Pribyl Vladimir
Published: October 2021

Investing in Human Resource Management (HRM), particularly in employee development through Further Education and Training (FET) at workplaces is a priority for most organisations. Our paper investigates how the participants perceive the effectiveness of particular FET methods based on an empirical study of 611 respondents from the millennial generation. The investigated sample consists of respondents employed at organisations operating in the Czech Republic. The results reveal that organisations are still regularly using certain traditional methods that do not correspond to the preferences of new employees (millennials) so are perceived as ineffective. The results should be useful for organisations seeking to adopt HRM policy and practice, particularly FET for the changes in the generation of employees.
Tackling undeclared work in Central and East Europe: an evaluation of competing public sector management approaches
Authors: Williams Colin C. , Horodnic Ioana Alexandra
Published: October 2021

To tackle undeclared work in Central and East Europe, the conventional bureaucratic public sector management approach has used the hard-direct controls of penalties and increasing the risk of detection. Recently, an alternative post-bureaucratic public sector management approach has emerged advocating soft indirect controls to improve tax morale and horizontal trust. Evaluating these competing approaches using evidence from Eurobarometer surveys conducted in 2007, 2013 and 2019 in six Central and East European countries, the finding is that both approaches significantly prevent undeclared work. The outcome is a call for a new ‘hybrid’ public sector management approach combining the two.
The effects of paternalistic leadership on task performance: Testing a moderated mediation model in Turkish organizations
Authors: Çetin Fatih , Karabay Melisa Erdilek , Şener İrge , Elçi Meral
Published: October 2021

Drawing on the findings from a serial moderated mediation model, this study aims to expand prior research by investigating the interaction between paternalist leadership and employee task performance. Study also aims to test the indirect effects of perceived person-organization fit and psychological ownership on the relationship between paternalistic leadership and employee task performance, through serial mediation models. Furthermore, the moderating role of organizational size in direct and all indirect relations between paternalistic leadership and task performance, through five different models is tested. Sample consists of 1,652 employees from various industries in İstanbul, Turkey. Hypothesized relationships were tested through structural equation modelling. The findings demonstrated the significant positive direct relationship between paternalistic leadership and employee task performance. Psychological ownership mediated the relationship of paternalistic leadership and task performance while person-organization fit had no mediating effect. Practical implications and further recommendations are also discussed.
Das Dunkelfelddelikt im Namen der Tradition: Genitale Verstümmelung an Mädchen und Frauen
Authors: Özalp Melisa , Kursawe Janet , von Buch Jennifer , Köhler Denis
Published: October 2021

Die weibliche Genitalverstümmelung (englisch: Female Genital Mutilation, FGM) ist ein grausames Jahrtausende altes Phänomen, welches in vielen Teilen der Erde als traditionelle Praxis an Mädchen und jungen Frauen verübt wird. Sie geht für die Betroffenen meist mit gravierenden physischen und psychischen kurzfristigen und Langzeitfolgen einher. Aufgrund der Immigration gibt es auch in Deutschland nicht nur eine Vielzahl von Betroffenen, sondern auch eine steigende Zahl an Mädchen, die von diesem körperverletzenden Ritual bedroht sind. Bereits seit mehreren Jahren besteht die Strafbarkeit bezüglich weiblicher Genitalverstümmelung in Deutschland, wodurch insbesondere Bedrohte vor dem Ritus geschützt werden sollen. Für den langfristigen Schutz ist in erster Linie eine gute Präventionsarbeit essentiell. Diese sollte nicht nur die Arbeit mit betroffenen bzw. bedrohten Mädchen und Frauen umfassen, sondern auch eine Aufklärung von besonders relevanten Berufsgruppen, wie Gynäkologen, Kinderärzten und anderem medizinischen Personal, aber auch Sozialarbeitern, Lehrern, Juristen und Polizei leisten, denen eine Schlüsselrolle im Kontakt zu Betroffenen und Gefährdeten zukommt.

Published: October 2021

Background: It is ensured that nurses’ error reporting and disclosing improve services to patients and are considered a movement toward creating a culture of transparency in the healthcare system. Objectives: This study aimed to investigate the nurses' decisions on reporting and disclosing Medical Errors (MEs). Methods: This research followed a mixed-method embedded design that was performed in five hospitals in Iran in 2018. A total of 491 nurses participated in the quantitative phase of the study with stratified sampling, followed by a simple random sampling technique. Also, 22 nurses joined the qualitative phase. Data were collected using a researcher-made questionnaire and semi-structured interviews through a scenario-based method. Quantitative data analysis was performed using descriptive and analytical statistics by SPSS 21.0 and Expert Choice 10.0 software. The qualitative data were analyzed based on the content analysis approach. Results: The most important perceived barriers with the highest impact coincided with educational (57.17%) and motivational (56.77%) factors based on SEM analysis (ES: 1.33, SE: 0.16). Regression analysis showed that error-reporting mechanisms, educational factors, and reporting consequences were significantly associated with age, sex, and work experience (P-Value ≤0.05). Error scenarios were thematized into three categories: Error perception (including ambiguity and weakness in error definition, the severity of the error, unawareness of guidelines, deviation from standards, and untrained staff), error reporting (including ineffective reporting system, hesitation in reporting to a formal system, increased workload, improper reaction, punitive responses, and concerns about consequences), and error disclosure (including no disclosure, partial disclosure, and full disclosure). Conclusions: The obtained results contributed to a better understanding of the barriers to error reporting and disclosing. In addition, these results can help hospitals encourage error reporting and ultimately make organizational changes, which reduce the incidence of errors.
Cosmopolitanism Without National Consciousness is not Radical
Authors: Valdez Inés ,   Philosophy Documentation Center
Published: October 2021

In this essay, I engage with the methodological contributions and original readings of Fanon and Rousseau contained in Jane Anna Gordon’s Creolizing Political Theory. I build upon one insight in particular––Gordon’s illuminating joint reading of Rousseau’s general will and Fanon’s national consciousness—in order to reflect on Fanon’s ambivalence about Pan-Africanism. In this task, I engage with W.E.B. Du Bois’s transnational thinking in order to parse out the tensions as well as the reciprocal relation between national consciousness and transnational or cosmopolitan engagements.
What is Nature in the Epoch of the Anthropocene?
Authors: Soeiro Diana ,   Philosophy Documentation Center
Published: October 2021

The epoch of the Anthropocene is on the verge of becoming scientifically acknowledged by the science of Geology. In what way does this concern Philosophy? In this paper, we evaluate how the new concept of the Anthropocene contrasts with the classical concept of Nature, aiming to identify the territory of both. In order to do this we take as our starting point the approach of Francis Bacon (1561-1626) which separates God and Nature. This later translated into the separation of Nature and Culture. The latter dualism is contested by Philippe Descola (b.1942) who defends the convergence of both. Bruno Latour (b.1947) and Timothy Morton (b.1968) consider the concept of nature as obsolete. Ulrich Beck (1944-2015), Erie C. Ellis and Mark Lynas (b.1973) claim that science will be able to cope with whatever changes the Anthropocene brings. We consider that all these claims, albeit apparently contrasting, are grounded in belief and as a counter-proposal we aim to bring to the table the concept of spirituality as essential to re-evaluate what Nature is today in the light of the Anthropocene.
The Kinship Model
Authors: Spaid Sue ,   Philosophy Documentation Center
Published: October 2021

Until Speculative Realism’s arrival a few years back, few philosophers found it problematic to view nature as a cultural construct, circumscribed and dependent on human attitudes (Berleant, 1992: 53). While I share speculative realists’ goal to strengthen philosophy’s mind-independence (Immanuel Kant’s goal as well), I worry that isolating nature as beyond human minds not only absolves human responsibility, but eradicates “kinship” relations, which capture non-hu­man nature providing for and sustaining human beings, and vice versa. To develop an environmental philosophy that affords mind-independence and offers evidence, unlike Positive Aesthetics, which idealizes wilderness, I discuss: 1) the pro/cons of nature’s mind-independence, 2) the implications for aspection, 3) the need for assessment tools that guide human action, 4) the reasons for grounding ethical action in kinship, and 5) recent research that suggests biodiverse cities exemplify the kinship model. Inseparable from nature, human beings are kindred participants in shared eco-systems.
John McDowell e o Naturalismo da Segunda Natureza
Authors: Sampaio da Silva Rui ,   Philosophy Documentation Center
Published: October 2021

John McDowell gave an important contribution to the debate on naturalism in the contemporary philosophy by proposing a “naturalism of the second nature”, which distinguishes itself by setting aside the conception of nature promoted by the modern science and for being based on the idea of second nature, reinterpreted in the light of the Sellarsian notion of the “logical space of reasons”, understood as the horizon of our world experience. He argues, accordingly, for the unboundedness of the conceptual sphere, which allows him to claim, in Mind and World, that experience justifies our beliefs because it is already conceptually articulated. The naturalism of the second nature extends to the domain of moral philosophy, gaining the form of a virtue ethics. The article points out some of the main problems of McDowell’s naturalism, like the difficulties underlying the experience conceptualism and the charge of idealism, offering also answers, inspired by McDowell himself, to these problems.
Que nada se sabe
Authors: Martinho Luís ,   Philosophy Documentation Center
Published: October 2021

Avid critic of the knowledge dependent of the old masters, Francisco Sanches strikes a direct blow at the heart of Aristotelic philosophy with the aim of demystifying the author par excellence of Scholasticism. Francisco Sanches, in this context, attempts to show that the human mind, for as sharp as it may be, is always fallible. In fact, shadows of truth show themselves if we search carefully. The whole history of philosophy proves this assertion, or had it not been more than a history of what was humanly capable of investigating. Some authors, possibly the most distinguishable, transcended the humanly capable of other authors, being therefore, unfortunately, treated as masters of knowing. Unfortunately indeed, as this dogmatic acceptance stagnates knowledge. Francisco Sanches visits exactly the classic masters of knowledge, and humbly shows the fallibility of the sapient assertions of Aristoteles.
Political Corrections: The Revolutionary Context and English Retranslations of Johann Georg Zimmermann’s Vom Nationalstolze [On National Pride] (1768)
Authors: Tarkka Laura
Published: October 2021

This article concerns the English translations of a popular eighteenth-century work on national pride. Originally entitledVon dem Nationalstolze[On National Pride], it was first published in 1758 and then twice revised by the author, Johann Georg Zimmermann (1728-1795). A physician by profession, the Swiss-born Zimmermann treated patriotism as a collective sentiment and soon attracted interest across Europe. Accordingly, the second revised editionVom Nationalstolze(1768) also appeared in a number of translations, including in English asAn Essay on National Pridefor the first time in 1771. Since an English retranslation by Samuel Hull Wilcocke was published in 1797 and yet another anonymous retranslation in 1805, the article examines these as attempts to correct the first English translation and to demonstrate the perceived relevance of the source text in the context of the French Revolutionary Wars. Starting from the premise that Zimmermann himself wrote about national pride in order to correct the false preconceptions of his readers, I argue that each translation also participated in the negotiation of a “healthy” form of patriotism. In so doing, the retranslation by Wilcocke in particular took considerable liberties in relation to the source text, while the second retranslator appears to have aspired to produce the most precise and transparent rendition of Zimmermann’s original words. However, as revealed by an examination of the linguistic transformations which the work underwent in Britain, all of the English translations adjusted its political meaning in ways that were significant to contemporary readers.

Published: October 2021

Development of Agricultural and allied activities can be achieved through various approaches of Information and communication (ICT) tools. Kisan Mobile Advisory system (KMAS) is one of ICT approaches for dissemination of agricultural technologies to the farming community through SMSs. KVK, Nagaon created a registered farmers group and information related to crop production, insect pest control, dairy and poultry farming, fishery and other marketing related information was sent to users in monthly basis for many years. A sample size of 100 registered farmers were selected for the study in order to examine the impact of KMAS for technology dissemination in Nagaon district.  With the help of Pretested scheduled with Simple Random sampling data were collected and analyze in percent analysis. The survey showed that majority of the farmers found agricultural information as increase in knowledge (41.00%), partially applicable (73.00%).  The overall impact of the KMAS was low About at 55 percent, medium at 38 per cent and high at 7 per cent. Further they suggested that messages on latest technologies should be served flowed by local language, voice messages.
Fighting for the Video Marketing against Its Weakness
Authors: (TF) Yen Tsai-Fa
Published: October 2021

As the market size of the video industry continues to grow by 3.6 times increased in the past five years, more and more companies adopt video marketing. Under this circumstance, it is meaningful and important to discuss the marketing issues in this industry. The objective of this study is to clarify the definition, problems and countermeasures of video marketing. Literature was obtained through data retrieval, and the data was aggregated and analyzed by induction. Findings show that the problems of video marketing cover the laws, suppliers, buyers, competitors, and content technical issues. And we suggest that the future research can try to verify the key points of STP analysis (segmentation, targeting, and positioning), marketing mix, as well as the cost-benefit analysis in video marketing.

Prospective Study: Optic Nerve Sheath ‎Diameter in Prediction of Fluid ‎Responsiveness in Sepsis Patients
Authors: Elsagheir Hadeel Ibraheim , Badawy Abd Elaziz Hamed El , Alrahman Reda Sobhi Salama Abd , Ghafar Mohamed Samir Abd El
Published: October 2021

Background: Sepsis is a life-threatening disease caused by the body's reaction to infection, which results in tissue destruction, organ failure, and death. Sepsis affects at least 30 million people worldwide each year, with 6 million people dying as a result. The goal of the research was to see whether the measurement of the Optic Nerve Sheath Diameter (ONSD) could be used to predict fluid responsiveness in hemodynamically unstable individuals.‎

Patients and Methods: This prospective observational (cohort) study was conducted at Tanta ‎University Hospitals in the Surgical Intensive Care Unit for 6 months at least ‎after approval from institutional ethics committee‎.

Results: Demographic data (sex, illiteracy, height, BMI) in our patients of the study there ‎were 34 (81%) male, 8 (19%) female, the age was average from 50.33 (±8.63 ‎SD) with range (25-65), 9 (21.4%) illiterate, 10 (23.8%) primary, 18 (42.9%) ‎secondary, 5 (11.9%) university, the mean value of weight 80.29 (±9.45 SD) ‎with range (60.7-98.8), the mean value of height 170.57 (±7.24 SD) with ‎range (157-182), the mean value of BMI 27.54 (±2.19 SD) with range (24.3-‎‎32).‎

Conclusion: In patients with sepsis, ocular ultrasonography appears to be a non-invasive and simple-to-learn technique for assessing overall fluid status. It may be particularly effective in finding those septic individuals who should avoid further fluid intake since it could cause pulmonary edema or other fluid-related problems.
High Normal Thyrotropin (TSH) is Associated with Higher Needed Dose of Erythropoietin in Hemodialysis Patients
Authors: Elsalam Rady Ibrahim Ali Abd , Elhamid Elkhateeb Mervat Abd , Mohamed Mabrouk Maaly , Elsayed Esheba Noha
Published: October 2021

Background: Recombinant human erythropoietin demonstrated an impressive ability to improve hematocrit, raising hematocrit of hemodialysis patients, eliminating the need for transfusions, and in patients with iron overload, decreased serum ferritin. Thyrotropin could affect hematopoiesis by binding to a functional thyrotropin receptor, which is found in both erythrocytes and some extrathyroidal tissues. The aim of this study was to evaluate the relationship of Thyrotropin level within normal reference range (in euthyroid state) on erythropoietin dose in end-stage renal disease patients on hemodialysis.

Methods: Prospective cross-sectional study was carried out at the hemodialysis units. It included 60 patients who had end-stage renal disease on hemodialysis. The selected patients were classified into 2 groups: Group A: included 30 end-stage renal disease patients on hemodialysis with Thyrotropin level (0.4-<2.5 miu/L) and Group B: included 30 end-stage renal disease patients on hemodialysis with Thyrotropin level (2.5-4.2 miu/L).

Results: the hemoglobin level and the hematocrit level showed a highly statistically significant difference between both groups. The needed Erythropiotin dosage was higher in group B than in group A with highly statistically significant difference. Weighted Erythropiotin dosage was calculated (weighted Erythropiotin=Erythropiotin dosage/weight) and the mean required dose was less than the required dose in group B and there was a highly statistically significant difference between the two groups. There was a significant negative correlation between the Thyrotropin level and hematocrit level and that leads us to conclude that the higher the Thyrotropin, the lower hematocrit will be and subsequently the higher Erythropiotin dose needed.

Conclusions: There is a relationship between Thyrotropin level even within normal reference range (in euthyroid state) on erythropoietin dose in end-stage renal disease patients on hemodialysis. In other words, the higher Thyrotropin level is, the more Erythropiotin dose needed. The required erythropoietin stimulating agent dose can be predicted by measuring Thyrotropin level.
Recovery of Nigerian Heavy Oil: Application of Steam Flooding
Authors: Evans Okoro Emmanuel , Onyekonwu Mike , Ajienka Joseph
Published: October 2021

Aims: Nigeria has a lot of conventional and heavy oil resources. Although much of the conventional oil resources have been developed since independence, the heavy oil resources have remained underdeveloped due to low recovery based on primary production and consequently doubts about economic viability based on the current fiscal regime. This paper examines the application of Steam Flooding enhanced oil recovery (EOR) method to suitable Nigerian heavy oil reservoirs, seeks to develop a diagnostic model to predict the performance, evaluates the economics to determine the viability of the EOR method. The development of heavy oil will increase Nigeria’s oil reserves and production.

Study Design:  Data was collected for two heavy oil reservoirs from two oil companies in Nigeria following a Non-disclosure Agreement (NDA).

Place and Duration of Study: Emerald Energy Institute, University of Port Harcourt Nigeria, 2016 - 2021.

Methodology: The screening criteria of commercially effective EOR methods were applied to select steam flooding for the studied reservoirs. Design of Experiment (DoE) was used to evaluate the reservoirs and operating parameters and to determine their optimum values, which were then used to predict the performance of the reservoirs. The economics of the steam flood technique endorsed for the reservoirs considered were also evaluated using Discounted Cash Flow Analysis (DCFA).

Results: These assessments confirmed that steam flooding technique was technically and economically viable for the heavy oil reservoirs considered. The steam flood was observed to have a good recovery efficiency of 24%, as against the waterflooding technique which had 13% OOIP and natural depletion of 9% for the offshore reservoir. For the onshore reservoir, the recovery efficiency was 20% for steam flood, and 4% for natural depletion. The economic analysis showed that even at a worst-case heavy oil price of US$15, the project was viable.

Conclusion: Steam flooding is viable, can be applied to develop heavy oil reservoirs in Nigeria that meet the screening criteria, and thus increase national oil reserve and production.

Recommendation: The fiscal policy should be adjusted, especially the petroleum profit tax from 85% to 50% as an incentive to operators and investors to embark on steam flooding and other EOR methods.
Lag Screws in Maxillofacial Trauma- A Review
Authors: Ramasubbu Subhashini
Published: October 2021

The etiology of mandibular fractures includes mainly assaults and road traffic automobile accidents. Additionally, fall and sports injuries are the foremost common causes for mandibular fractures. Mandibular fractures outnumbered zygomatic and maxillary fractures by a ratio of 6:2:1, respectively. Road traffic accidents is that the most typical etiology, followed by assaults and sport-related injuries. For the management of maxillofacial trauma, the treatment commonly done is open reduction and Internal Fixation using miniplates. Lag screws as compared with plates, have a plus of the necessity of minimum implant material which they also provide maximum stability. The lag screw placement is a simple method of rigid fixation. The choice of the lag screw technique depends on patient factors, kind of fracture, site of fracture, and thus the skill of surgeon. The aim of this review is to assess the efficiency of Lag Screws for the management of maxillofacial trauma.
Formulation and Evaluation of Vaginal Bioadhesive Drug Delivery System of Acyclovir
Authors: Mohite Bhaskar , Patel Rakesh , Kayande Nandu
Published: October 2021

Acyclovir is an anti-viral, which has been used in the treatment of vaginal disorder. Acyclovir is almost completely absorbed after oral administration but has low bioavailability of about 10-15% because of first pass metabolism. As first pass metabolism removes approximately 85-90% of the drug, so for clinical efficacy of the drug it should be frequently administered. Hence an attempt has been made to produce sustained release dosage form of the acyclovir which can be specifically employed for the treatment of vaginal disordered by Herpes simplex virus. The Mucoadhesive tablets of acyclovir has been prepared by direct compression methods and evaluated for various parameter such as thickness, friability, hardness, drug content, weight variation, swelling index, surface pH, bioadhesive force, bioadhesive time, drug release etc. The kinetic data was applied to the optimized formulations. So formulation of acyclovir in a vaginal mucoadhesive tablet dosage form will decrease the frequency of administration, which can lead to an improvement in patient adherence and thereby improving its clinical efficacy.

Authors: Peluri Kalyani , Rajasekaran S.
Published: October 2021

Aim: The foremost purpose of this research work is to diminish the analysis time and to establish cost effective method for estimation of Vildagliptin by RP-UPLC.

Study Design: UPLC based Quantification studies.

Place and Duration of Study: Department of Pharmacy, Bhagwant University, Ajmer, Rajasthan, Indiabetween June 2020 and August 2020.

Methodology: A simple, responsive and precised RP-UPLC method with good robustness was developed and validated as per ICH for the analysis of Vildagliptin in drug substance and separation of degradants generated by different forced degradation conditions. Productive separation of Vildagliptin was attained by the use of Luna C18 column (100x2.6mm and 1.6µm) with a mobile phase composition of 0.1% v/v Trifluoroacetic acid and Acetonitrile in 80:20 v/v, which was pumped with 0.5 ml/min flow rate. The eluted substances were examined with PDA detector at 239nm. Stressed degradation studies were performed with proposed method to determine the percentage degradation of Vildagliptin.

Results: The RT of Vildagliptin was observed at 1.56 min. The developed method was validated as per ICHQ2B and proved that the method was precise, sensitive, specific and accurate.The lowest concentration of limit of detection (0.05µg/ml) and limit of quantification(0.5µg/ml) of Vildagliptin make obvious about the sensitivity of the method. The correlation coefficient found to be 0.9997 for given range of linear concentrations. The calculated average percentage recoveries of Vildagliptin in spiked solutions were found to be in the range of 99.1-100.5. The calculated % RSD was determined to be less than 2. Determination of degradation of amount of Vildagliptin by forced degradation studies representing the stability indicating nature of the proposed method.

Conclusion: The developed method said to be highly sensitive, accurate, specific and robust, therefore this method has high probability to adopt in pharmaceutical industry for regular analysis of Vildagliptin.

Published: October 2021

COVID-19 has had a worldwide impact that is unprecedented and catastrophic. Infection with COVID-19 can cause various neuropsychiatric complications, including delirium, which is commonly reported with the acute phase of illness with COVID-19 infection. However, delirium after complete recovery from mild COVID-19 infection has never been reported. Here we present the first case for a 58-year-old male diagnosed with a positive COVID-19 infection with a PCR test after a 1-day history of headaches and loss of taste and smell. By 10 days after the positive PCR test, the patient recovered completely without any recurrence of symptoms. However, the patient was observed to be unaware of their surroundings and displayed changes in their behaviour 11 days after recovery from mild COVID-19 infection. Physical examinations were abnormal, while the lab tests and the brain images showed normal results. The patient started to improve on the second day of admission without presenting any decline in health. Delirium that develops after recovering from COVID-19 infection should be investigated thoroughly to determine the reason; if no clear cause can be identified, the delirium may be secondary to COVID-19 infection.
Psychotherapy for end times
Authors: Romanyshyn Robert
Published: October 2021

The broken connections between us and nature have left us feeling homeless in a world not only imperiled by multiple ecological crises and their political, economic, medical and social consequences, but also orphaned by the increasing turn to the allures of the digital world with its loss of place and embodied presence. In this context, this essay proposes that psychotherapy can be a place for homecoming in a fractured world. Exploring the key role of the grieving process in homecoming, I draw on my work in Jungian psychology, phenomenology, poetry and storytelling to show that our engaged, embodied presence with nature can re-mind us of the miracles in the mundane, the extraordinary in the ordinary, and can open our hearts to the wonder, mystery, beauty and sacred dimensions of human life.
Thinking and not being able to think
Authors: Hirschfeld Alisa
Published: October 2021

In this paper I draw on valuable perspectives from a range of psychoanalysts in the British psychoanalytic tradition to understand a particular transference-countertransference dynamic, namely one in which the therapist is rendered unable to think. I explore what makes the capacity to think possible and what gets in the way of thinking.
In person online

Published: October 2021

During the 2020 lockdown in response to COVID-19, students in the Master of Psychotherapy at the Auckland University of Technology (AUT) were required to rapidly move their clinical work online. We surveyed these students about their experience of working clinically online. We used a mixed-methods approach and analysed qualitative data using grounded theory methods. Students found the move online difficult, with technological challenges, the loss of a professional clinical space, and having to establish and maintain the therapeutic alliance in the unfamiliar online setting. They showed a strong preference for in-person clinical work, along with scepticism about the efficacy of online therapy, though some acknowledged its convenience and others its currency and relevance. Most expressed a need for more specific training in online therapy. Students rated their technological skill level higher than their levels of interest in online communication. This suggests that preferences, rather than technical skill, influenced their hesitancy for working clinically online. While online therapy can impose increased strain on clinicians and directly impact their capacity to manage online clinical work, the literature finds strong and consistent evidence that online therapy has equivalent outcomes to in-person therapy. There is significant emphasis in the literature on the disjunct between the outcomes evidence and therapist expectations. This is modified somewhat by training and experience in online therapy. We recommend that research- active psychotherapists engage actively and collaboratively with the profession, through professional bodies, to encourage research-informed professional development and practice for clinicians; and that further research is conducted into effective strategies for training in online clinical delivery.

Spin defects in hexagonal boron nitride, and specifically the negatively charged boron vacancy (VB‐) centers, are emerging candidates for quantum sensing. However, the VB‐ defects suffer from low quantum efficiency and, as a result, exhibit weak photoluminescence. In this work, a scalable approach is demonstrated to dramatically enhance the VB‐ emission by coupling to a plasmonic gap cavity. The plasmonic cavity is composed of a flat gold surface and a silver cube, with few‐layer hBN flakes positioned in between. Employing these plasmonic cavities, two orders of magnitude are extracted in photoluminescence enhancement associated with a corresponding twofold enhancement in optically detected magnetic resonance contrast. The work will be pivotal to progress in quantum sensing employing 2D materials, and in realization of nanophotonic devices with spin defects in hexagonal boron nitride.

An acoustic liquefaction approach to enhance the flow of yield stress fluids during Digital Light Processing (DLP)‐based 3D printing is reported. This enhanced flow enables processing of ultrahigh‐viscosity resins (μapp > 3700 Pa s at shear rates  = 0.01 s–1) based on silica particles in a silicone photopolymer. Numerical simulations of the acousto–mechanical coupling in the DLP resin feed system at different agitation frequencies predict local resin flow velocities exceeding 100 mm s–1 at acoustic transduction frequencies of 110 s–1. Under these conditions, highly loaded particle suspensions (weight fractions, ϕ = 0.23) can be printed successfully in complex geometries. Such mechanically reinforced composites possess a tensile toughness 2000% greater than the neat photopolymer. Beyond an increase in processible viscosities, acoustophoretic liquefaction DLP (AL‐DLP) creates a transient reduction in apparent viscosity that promotes resin recirculation and decreases viscous adhesion. As a result, acoustophoretic liquefaction Digital Light Processing (AL‐DLP) improves the printed feature resolution by more than 25%, increases printable object sizes by over 50 times, and can build parts >3 × faster when compared to conventional methodologies.

Electromagnetic (EM) absorbers play an increasingly essential role in the electronic information age, even toward the coming “intelligent era”. The remarkable merits of heterointerface engineering and its peculiar EM characteristics inject a fresh and infinite vitality for designing high‐efficiency and stimuli‐responsive EM absorbers. However, there still exist huge challenges in understanding and reinforcing these interface effects from the micro and macro perspectives. Herein, EM response mechanisms of interfacial effects are dissected in depth, and with a focus on advanced characterization as well as theoretical techniques. Then, the representative optimization strategies are systematically discussed with emphasis on component selection and structural design. More importantly, the most cutting‐edge smart EM functional devices based on heterointerface engineering are reported. Finally, current challenges and concrete suggestions are proposed, and future perspectives on this promising field are also predicted.
Effects of surface species and homogeneous reactions on rates and selectivity in ethane oxidation on oxide catalysts

Selective alkane oxidations on metal oxide catalysts involve complex mechanisms with multiple reactions in series and parallel, different types of reduced and oxidized surface species, and potential contributions from gas‐phase reactions. Here, kinetics and thermodynamics of elementary steps involved in C2H6‐O2 reactions on SiO2‐supported small vanadium oxide domains are determined using density functional theory. These surface reactions together with gas‐phase mechanisms are incorporated in kinetic simulations to determine how surface and gaseous reactions interact and contribute to rates and selectivity. The results show that gas‐phase reactions within pore volumes in contact with the catalyst contribute significantly to C2H6 activation rates, even at conditions where gas‐phase reactions in empty volumes without catalyst are negligible. The majority of C2H6 activations occur on the surface, via H abstraction by vanadium oxo species present at terminal lattice oxygens. The gas‐phase activations via H‐abstraction by OH radicals also exhibit significant contributions. The reduced centers formed by reactions at vanadium oxo species are re‐oxidized rapidly and, therefore, are present in very small concentrations at reaction conditions. The re‐oxidation steps lead to the formation of HO2 radicals and surface peroxo species that are also rapidly consumed and are present in small concentrations. The peroxo species preferentially convert C2H4 to its epoxide product and influence selectivity even at low concentrations. The gas‐phase reactions decrease the concentrations of peroxo species and improve selectivity slightly. The effects of reaction conditions and catalyst site density provide further insights into how factors beyond conversions at lattice oxygens influence rates and selectivity in alkane oxidation reactions of significant industrial importance.

In this work, the efficiency of partially hydrophobized hyperbranched polyglycerols (HPG11 and HPG12) as cetyltrimethylammonium bromide (CTAB) carriers was evaluated to prevent surfactant losses by adsorption on reservoir rocks surface during enhanced oil recovery (EOR) processes. Interactions between surfactant and polymers were studied by conductivity, zeta potential, and particle size measurements showing that complexes were formed between the components. The ability of PG, HPG11, HPG12 and those complexes to reduce the interfacial tension (IFT) was verified and one of the complexes was able to reduce the IFT to values under 1.0 mN/m, suggesting the occurrence of a synergy between the components. Molecular dynamics simulations indicated the preferential sites of interaction between surfactants and HPGs. HPG11:CTAB and HPG12:CTAB complexes' ability to permeate an unconsolidated porous medium and deliver the surfactant at the water–oil interface, increasing oil production, was evaluated through transport and oil displacement tests, and the results showed that the HPG12:CTAB complex led to almost 90% of oil recovery.
Assisting researchers in bibliographic tasks: A new usable, real‐time tool for analyzing bibliographies
Authors: Dattolo Antonina , Corbatto Marco
Published: October 2021

The amount of scientific papers is growing together with the development of science itself; but, although there is an unprecedented availability of large citation indexes, some daily activities of researchers remain time‐consuming and poorly supported. In this paper, we present Visual Bibliographies (VisualBib), a real‐time visual platform, designed using a zz‐structure‐based model for linking metadata and a narrative, visual approach for showing bibliographies. VisualBib represents a usable, advanced, and visual tool, which simplifies the management of bibliographies, supports a core set of bibliographic tasks, and helps researchers during complex analyses on scientific bibliographies. We present the variety of metadata formats and visualization methods, proposing two use case scenarios. The maturity of the system implementation allowed us two studies, for evaluating both the effectiveness of VisualBib in providing answers to specific data analysis tasks and to support experienced users during real‐life uses. The results of the evaluation are positive and describe an effective and usable platform.

Objectives

This study explores the factors involved in the intention to seek support from mental health services among students, emphasising the role of subjective norms in this process.

Methods

Factors involved in students’ intentions to seek support from mental health services were explored using regression analysis, based on survey data from 1,494 Russian students (from high schools, vocational schools and universities). Independent variables included perceived injunctive and descriptive norms towards mental health help‐seeking, previous experience of utilising mental health services and mental health symptoms.

Findings

Less than a quarter of students had the intention to seek psychological help in case of distress. Just half of the students felt that others would support them in seeking psychological help (injunctive social norms), although only 10% believed their peers would seek help when needed (descriptive norms). Only injunctive, but not descriptive, social norms were associated with the intention to seek help. Experience of visiting a psychologist (only in the case of self‐referral) was another important predictor of intention to seek help. Male students and those who considered their mental health to be bad or perfect showed less intention to seek help.

Conclusion

Provision of mental health services for students should be accompanied by interventions aimed at establishing positive attitudes towards mental health‐seeking among the general population, particularly those whose opinion is important for students. A gender‐specific approach should be introduced in delivering and promoting mental health care since male students are more hesitant to accept care and might face strong negative feedback from their social environment when doing so.
