Climate depression. Critical analysis of the concept
Authors: Budziszewska Magdalena , Kałwak Weronika
Published: March 2022

Celem artykułu jest namysł nad ryzykiem dla zdrowia psychicznego niesionym przez współczesną zmianę klimatu. Refleksja oparta jest o przegląd literatury i własne eksploracyjne badania jakościowe. Analizie poddano dane zastane i dane pozyskane w pogłębionych wywiadach z przedstawicielami takich grup jak: młodzież szkolna, studenci, młodzi rodzice, aktywiści i pacjenci psychoterapii. Zaprezentowano krytyczny przegląd współczesnej terminologii stosowanej na określenie trudności psychicznych i emocji przeżywanych w związku ze zmianami klimatu, a także historię podejmowania tematu w literaturze naukowej. Artykuł koncentruje się na pojęciu i zjawisku depresji klimatycznej, które poddano dyskusji w kontekście wyników badań jakościowych oraz głównych argumentów krytycznych wobec medykalizacji emocji przeżywanych w obliczu kryzysu klimatycznego. Uzupełniająca analiza społeczno-politycznych i kulturowych aspektów styku problemu zmiany klimatu i zdrowia psychicznego pozwoliła sformułować wniosek o konieczności dalszych badań, w celu uzyskania wielowymiarowego rozumienia tego obszaru, które mogłoby stać się podstawą adekwatnej pomocy psychologicznej. Jest bardzo prawdopodobne, że będzie ona w przyszłości coraz bardziej potrzebna.
Ganser syndrome – a dissociative disorder or a factitious disorder? A case report
Authors: Wincewicz Karolina , Sapota-Zaręba Karolina , Nasierowski Tadeusz
Published: March 2022

Zespół Gansera (ZG) jest jednym z niewielu eponimów, które przetrwały w historii psychiatrii do czasów obecnych. ZG jest mało znanym i rzadko występującym schorzeniem. Najczęściej opisywany jest jako odpowiedź na stresogenną sytuację (np. pozbawienie wolności), dlatego stanowi istotne zagadnienie w opiniowaniu sądowo-psychiatrycznym. W etiologii bierze się także pod uwagę podłoże organiczne. Jako podstawowe objawy zespołu wymienia się: przybliżone odpowiedzi, omamy wzrokowe i słuchowe, przymglenie świadomości oraz objawy konwersyjne. Dodatkowo może występować opaczne wykonywanie prostych czynności oraz niewrażliwość na bodźce bólowe. ZG zwykle charakteryzuje się ostrym przebiegiem i spontaniczną remisją. Zazwyczaj występuje niepamięć epizodu chorobowego. Kryteria diagnostyczne ZG są nieprecyzyjne, a jego pozycja klasyfikacyjna ulegała zmianie na przestrzeni lat. W klasyfikacji DSM-5 ZG został całkowicie pominięty, choć w DSM-IV zaliczany był do zaburzeń dysocjacyjnych. Obecnie część autorów skłania się bardziej do klasyfikowania go jako zaburzenia pozorowanego. W klasyfikacjach opracowanych przez WHO (ICD-10 oraz ICD-11) ZG zaliczany jest do zaburzeń dysocjacyjnych (konwersyjnych), co wydaje się być, w świetle obecnej wiedzy, najbardziej właściwe. Przedstawiony opis przypadku dotyczy pacjenta, u którego dwukrotnie wystąpił niemal identyczny schemat pojawienia się pełnoobjawowego ZG. Objawy pojawiły się w krótkim czasie po osadzeniu w zakładzie karnym. Przebieg był przewlekły i nawracający. Pacjent wykazywał niewrażliwość na bodźce bólowe. Przeprowadzona diagnostyka wykluczyła możliwość podłoża somatycznego.

A Framework for Studying Decentralized Bayesian Learning with Strategic Agents
Authors: Vasal Deepanshu , Anastasopoulos Achilleas
Published: March 2022

We study the problem of Bayesian learning in a dynamical system involving strategic agents with asymmetric information. In a series of seminal papers in the literature, this problem has been investigated under a simplifying model where selfish players appear sequentially and act once in the game. It has been shown that there exist information cascades where users discard their private information and mimic the action of their predecessor. In this paper, we provide a framework for studying Bayesian learning dynamics in a more general setting than the one just described. In particular, our model incorporates cases where players can act repeatedly and there is strategic interaction in that each agent’s payoff may also depend on other players’ actions. The proposed framework hinges on a sequential decomposition methodology for finding structured perfect Bayesian equilibria of a general class of dynamic games with asymmetric information. Using this methodology, we study a specific dynamic learning model where players make decisions about public investment based on their estimates of everyone’s states. We characterize a set of informational cascades for this problem where learning stops for the team as a whole. Moreover, we show that such cascades occur almost surely.

Published: March 2022

Profesi aktuaris sangat digemari oleh masyarakat Indonesia karena luasnya prospek kerja yang ditawarkan serta adanya peraturan Menteri Keuangan tahun 2016 yang mewajibkan penugasan dan laporan aktuaris di tandatangani oleh Aktuaris Publik. Seorang aktuaris memiliki syarat yaitu harus lulus pada 10 ujian sertifikasi yang diselenggarakan oleh Persatuan Aktuaris Indonesia (PAI). Tingginya kebutuhan tenaga aktuaris tidak diimbangi oleh peningkatan jumlah aktuaris di Indonesia. Salah satu penyebabnya adalah gagal dalam ujian PAI. Salah satu mata ujian yang diujikan oleh PAI adalah A10, yaitu matematika finansial. Mata ujian A10 merupakan materi paling dasar pada seluruh mata ujian profesi aktuaris. Apabila seorang peserta telah berhasil menyelesaikan mata ujian A10, maka peserta tersebut dapat melanjutkan ujian ke tingkat berikutnya yang lebih tinggi. Oleh karena itu, tim pengabdi mengidentifikasi bahwa salah satu cara untuk mendukung para peserta ujian PAI serta membantu pemerintah dalam meningkatkan jumlah aktuaris di Indonesia adalah dengan menyelenggarakan pelatihan/short course pada mata ujian A10. Metode yang digunakan pada kegiatan ini adalah observasi, bimbingan dan evaluasi yang diikuti oleh peserta selama empat hari dalam bentuk penyampaian konsep dasar materi oleh narasumber, pembahasan soal yang didampingi oleh asisten narasumber serta pre-test dan post-test. Kegiatan ini diharapkan dapat membantu peserta untuk lulus ujian PAI pada subjek A10.
A supraventricular tachycardia with a possible accessory pathway in a young Labrador Retriever
Authors: Crosland Andrew , Love Brian
Published: March 2022

A supraventricular tachycardia was diagnosed in a 3-year-old male Labrador Retriever. Based on patient signalment and characteristic electrocardiographic findings, an accessory pathway bypassing the normal atrioventricular nodal pathway causing an atrioventricular reciprocating tachycardia was a differential diagnosis. However, an alternative diagnosis of a focal atrial tachycardia was another possibility. The dog was successfully treated short-term with intravenous diltiazem, and long-term with modified release oral diltiazem. This report shows the utility of the electrocardiogram in the diagnosis of a supraventricular tachycardia, as well as the medical management for this emergency case.
A surgical approach to the reptile patient
Authors: Miles Sonya
Published: March 2022

Reptile surgery, as well as owner expectations for the care of reptiles, is constantly evolving. It is essential that the unique anatomical and physiological differences between reptiles and mammal patients, as well as between reptiles of different groups, be fully understood before undertaking any surgery. All reptile patients should undergo a full clinical examination and be stabilised wherever possible before surgery, with the patient's preferred optimum temperature being ensured pre-, peri- and postoperatively to optimise drug metabolism and wound healing. It is important to optimise patient and surgeon positioning, use appropriately sized suture material, and maintain haemostasis, magnification and lighting to improve surgical technique, regardless of the procedure or organ system being operated on.

Herbal medicines like Esberitox (TOX, wild indigo root stock, echinacea root, thuja tips and leaves) are used to treat common colds. Several randomized, controlled trials (RCT) document the efficacy and safety of TOX in this indication. So far its efficacy and safety has not been evaluated meta-analytically.

We included individual patient data from all 825 patients from 3 RCTs. 693 patients had been treated with TOX, 132 with placebo (PLA) (7-9 days). All symptom scores were adjusted to baseline and meta-analyzed regarding area under the curve (AUC), time to response (≥50% decrease of symptom score), response rate and duration of the cold.

The AUCs of the rhinitis score were 19.05 with TOX superior to 20.57 with PLA (p=0.020), bronchitis score 14.92 versus 16.16 (p=0.039) and well-being 208.4 versus 216.4 (p=0.008). Response rates were higher in TOX than PLA in all scores. The times to response showed an acceleration of the healing process of rhinitis (1.5 days, p=0.049), bronchitis (2 days) and pain (2 days, p=0.008). The duration of the cold was shortened by TOX by up to 2.3 days. The ADR-rate did not differ significantly (2.7% vs. 1.5%, p=0.41). Tolerability was good to very good in 98.4% (TOX) and 99.2% (PLA) (p=0.34). In conclusion, this meta-analysis confirmed the efficacy and tolerability of Esberitox at a higher level of evidence. It accelerates the improvement of cold symptoms by up to 2 days and shortens the duration of colds by up to 2.3 days.

Stress Analysis of the Cylinder Block in an Axial Piston Pump
Authors: Baus Ivan , Rahmfeld Robert , Schumacher Andreas , Pedersen Henrik C.
Published: March 2022

For axial piston units, product optimisation plays an essential role in the development phase, where an efficient and price-attractive product design and manufacturing process is the key to the success of a product. Moreover, the market needs are on lighter, more compact, efficient, and reliable products designed to the limit. Therefore, reliability is the focus of this work, where the research includes method analysis of the material stress calculation applied to the cylinder block implemented in an axial piston pump. A simplified calculation model is presented and evaluated concerning load while remaining accessible for users without deep technical knowledge or access to expensive Finite Element (FE) simulation tools. The analytical calculation method delivers a stress distribution intended for different purposes like design evaluation or as load spectrum for lifetime calculation. Additionally, the developed calculation method is generalised, enabling the methodology to be used on any standard axial piston pump. The methodology utilises the stress determination model, which includes the load as a sum of forces caused by the external and internal influencing factors. To show the method’s success, a comparison demonstrates strong positive agreement between the calculated and simulated stress results obtained by Finite Element Analysis.
Performance Analysis of Orthogonal Gradient Sign Algorithm Using Spline-based Hammerstein Model for Smart Application
Authors: Sitjongsataporn Suchada , Prongnuch Sethakarn
Published: March 2022

This paper presents a spline-based Hammerstein model for adaptive filtering based on a sign algorithm with the normalised orthogonal gradient algorithm. Spline-based Hammerstein architecture consists of an interpolation spline-based adaptive lookup table in the part of nonlinear filter and an adaptive finite impulse response filter used in the part of linear filter. Hammerstein spline adaptive filter (HSAF) is a nonlinear filter for the nonlinear systems among the advantages in the low computational cost and high performance. An adaptive lookup table and spline control points are determined and derived with the orthogonal gradient-based mechanism. Performance analysis in terms of convergence properties and mean square analysis based on the mean square error (MSE) constraint are proven by using the Taylor series expansion of the estimation error in the form of the excess MSE. Experimental results indicate the robust performance of the proposed algorithm can provide the better performance than the other models based on the conventional least mean square Hammerstein spline adaptive filtering algorithm.
Effect of annealing on properties and performance of HfO2/SiO2 optical coatings for UV-applications
Authors: Falmbigl Matthias , Godin Kyle , George Jason , Mühlig Christian , Rubin Binyamin
Published: March 2022

The field of ultraviolet (UV)-laser applications is currently experiencing rapid growth in the semiconductor processing, laser micromachining and biomedical markets. Key enablers for these technologies are optical coatings used to manipulate and guide laser beams in a targeted manner. As laser power, laser fluence and pulse frequencies increase, the demands on the physical properties of the coating materials become more stringent. Ion beam sputtering is a technique that allows producing optical coatings with the low losses required in these applications. In this study, we investigate the influence of ion beam sputtering (IBS) parameters on the optical properties of HfO2 and SiO2 single layers as well as the impact of annealing duration at 475 °C for anti-reflective (AR) and highly reflective (HR) optical coatings at 355 nm. For HfO2 sputtered from a metal target the O2 flow during the coating process is a key parameter to reduce absorption. SiO2 single layers exhibit improved transmission in the UV-range as the ion beam energy for the sputtering process is reduced. Furthermore, a complex behavior for film stress, absorption, surface roughness and coating structure was unraveled as a function of annealing duration for AR- and HR-coatings at 355 nm. The reflectance of the HR-mirror after optimized annealing exceeded 99.94% at 355 nm and a high laser induced damage threshold (LIDT) of 6.9 J/cm2 was measured after 2 hours of annealing. For the AR-coating a LIDT-value of 15.7 J/cm2 was observed after 12 hours of annealing.
Efficacy of PEGylated ciliary neurotrophic factor superagonist variant in diet-induced obesity mice

Published: March 2022

Ciliary neurotrophic factor (CNTF) is a neurotrophic cytokine able to induce appetite reduction, weight loss and antidiabetic effects. However, its susceptibility to neutralizing anti-CNTF antibodies in patients hampered its use for treatment of human obesity and diabetes. In addition, CNTF has a very short plasma half-life, which limits its use as a therapeutic agent. Solutions, directed to prolong its in vivo effects, vary from the implantation of encapsulated secreting cells to identification of more active variants or chemical modification of the protein itself. PEGylation is a widely used modification for shielding proteins from circulating antibodies and for increasing their plasma half-life. Here, we have selected DH-CNTF, a CNTF variant which has a 40-fold higher affinity for the CNTF receptor α accompanied by an increased activity in cellular assays. The PEGylated DH-CNTF retained the biological activity of native protein in vitro and showed a significant improvement of pharmacokinetic parameters. In an acute model of glucose tolerance, the PEG-DH-CNTF was able to reduce the glycemia in diet-induced obese animals, with a performance equaled by a 10-fold higher dose of DH-CNTF. In addition, the PEGylated DH-CNTF analog demonstrated a more potent weight loss effect than the unmodified protein, opening to the use of CNTF as weight reducing agent with treatment regimens that can better meet patient compliance thanks to reduced dosing schedules.
Soliman’s legacy: What Mozart has to teach us about race in musical theatre
Authors: LaReau Brandon
Published: March 2022

This article serves to describe and activate conversations about racial representation in the musical theatre by expanding the musical theatre’s traditional boundaries to include Mozart, his operas and his collaborations as origins of the genre. By examining in particular the exemplary and understudied life of Angelo Soliman, the Enlightenment’s views on race come into sharp focus, raising the questions: how deep is the gap between fetishization and fascination – and what can theatre practitioners learn from Mozart’s history?

The two waves of virtual reality in artistic practice
Authors: Doyle Denise
Published: March 2022

As the title of this article suggests, there appears to be two distinct waves of artistic engagement with virtual reality (VR) in artistic practice: the first during the initial technological development in the 1990s that enabled VR to become accessible to artists such as Char Davies and Toni Dove among others and the current second wave that has been based on a much greater accessibility of immersive headsets for artists and a wider general public, driven by both market forces and technological development. The term ‘virtual reality’ has been interchangeably used to mean virtual environments and virtual worlds, but here the aim is to solely examine the use of VR in artistic practices, where the intention is for the participant to largely experience the virtual space through total immersion, reserving the analysis of the mixed use of VR within mixed-reality environments to another study. The article begins with a brief history of the development of VR and an analysis of the key works created in what can be termed the first wave, before discussing the current use of VR in contemporary practices through the notion of affect in VR.
FCS Teacher Recruitment and Retention As Related to Classroom Environment and Teacher Productivity
Authors: Pulay Alana , Tripp Paula J.
Published: March 2022

Family and consumer sciences (FCS) educators were surveyed in the state of Oklahoma to gather information regarding their satisfaction with the classroom interior environment to reveal whether classroom satisfaction is related to the educators' productivity levels. Past research suggests
that teachers who are satisfied with their working environments have higher levels of productivity and tend to stay in their jobs longer. Results of this study indicated that the FCS educators are mostly satisfied with their classrooms and have high levels of productivity, although statistical
associations between satisfaction with interior environments and productivity were not detected. This information can be applied in both recruiting new FCS teachers and retaining current FCS teachers.
Experiential Learning in a Family Systems Course: Integrating the FCSfit KIDS Curriculum
Authors: Williams -Wheeler Meeshay , Burwell Jawan M. , Gravely Gabrielle S. , Summers-Dawkins Raleta
Published: March 2022

Experiential learning is a pedagogical tool that aligns with the mission of family and consumer sciences (FCS) university programs because it emphasizes the role of formal education in the development of individuals, family members, and global citizens (Brooks & Simpson, 2014).
College students benefit from experiential learning and field-based experiences through enhanced integration of course materials and enhanced perceptions of learning and actual learning (Langlais, 2018). There are many positive outcomes of experiential learning activities in the college classroom
including high retention rates of students during and after these semesters (Darling & Cassidy, 2014), improved employability (Brooks & Simpson, 2014), and a broader global perspective (Smith & Yang, 2017). Within FCS courses, experiential learning often provides skills that prepare
college students to succeed in their work with children, youth, and families (Brooks & Simpson, 2014; Taylor & Xia, 2018). This paper highlights an experiential activity provided in a Family Systems course in which students learn about family dynamics and the systematic approach of
familial well-being. With its focus on the application, creativity, and linking theory to practice, the FCSfit KIDS curriculum was implemented in a Family Systems course to provide varied interactive learning activities to enhance students' understanding of the role of families on preschoolers'
health and well-being.

Objectives: We surveyed 287 American women from April 2020 until the November 2020 presidential election to evaluate their primary news source, beliefs on the constitutionality of mask-wearing and stay-at-home orders, government’s ability to implement public health orders, and political affiliation. Methods: Qualtrics surveys were distributed on social media. Using a chi-square test of independence, we evaluated differences by age groups, ethnicity, and education. Results: Age, ethnicity, and education were all statistically related to beliefs about public health initiatives. Conclusions: These results can help tailor public health interventions, policies, and laws focused on compliance with public health initiatives aimed at reducing the spread of the virus.
Detecting Deepfakes with Deep Learning and Gabor Filters
Authors: Jameel Wildan J. , Kadhem Suhad M. , Abbas Ayad R.
Published: March 2022

The proliferation of many editing programs based on artificial intelligence techniques has contributed to the emergence of deepfake technology. Deepfakes are committed to fabricating and falsifying facts by making a person do actions or say words that he never did or said. So that developing an algorithm for deepfakes detection is very important to discriminate real from fake media. Convolutional neural networks (CNNs) are among the most complex classifiers, but choosing the nature of the data fed to these networks is extremely important. For this reason, we capture fine texture details of input data frames using 16 Gabor filters indifferent directions and then feed them to a binary CNN classifier instead of using the red-green-blue color information. The purpose of this paper is to give the reader a deeper view of (1) enhancing the efficiency of distinguishing fake facial images from real facial images by developing a novel model based on deep learning and Gabor filters and (2) how deep learning (CNN) if combined with forensic tools (Gabor filters) contributed to the detection of deepfakes. Our experiment shows that the training accuracy reaches about 98.06% and 97.50% validation. Likened to the state-of-the-art methods, the proposed model has higher efficiency.

Current-Account Imbalances, Real Exchange-Rate Misalignments, and Output Gaps
Authors: Camba-Crespo Alfonso , García-Solanes José , Torrejón-Flores Fernando
Published: March 2022

This study analyzes the relationships between domestic and foreign output gaps, current-account imbalances, and real effective exchange-rate (REER) misalignments. We first set up a theoretical framework based on the elasticities and absorption approaches of the balance of payments to derive and clarify these relationships. Next, we perform panel VAR estimates in a sample of 18 advanced economies between 1986 and 2017. We find an inverse relationship between domestic output gaps and current accounts with reciprocal influences between the two variables. Moreover, we observe that increases in current accounts generally boost both temporary and structural growth. Additionally, our results indicate that REER misalignment shocks cause reactions of the opposite sign on the current account and on cyclical economic growth. We also find evidence of higher growth resulting in a real exchange-rate appreciation, which supports the Balassa–Samuelson hypothesis.

A series of 2,2-difluoro-2-arylethylamines was synthesized as fluorinated analogs of octopamine and noradrenaline with the expectation of bioisosteric OH/F exchanges. The syntheses of these compounds were performed by a Suzuki–Miyaura cross-coupling reaction of 4-(bromodifluoroacetyl)morpholine with aryl boronic acids to produce the intermediate 2,2-difluoro-2-arylacetamides, followed by transformation of difluoroacetamide to difluoroethylamine.
Regularizing ill-posed problem of single-epoch precise GNSS positioning using an iterative procedure
Authors: Fischer Artur , Cellmer Sławomir , Nowel Krzysztof
Published: March 2022

This paper analyses the regularization of an ill-conditioned mathematical model in a single-epoch precise GNSS positioning. The regularization parameter (RP) is selected as a parameter that minimizes the criterion of the Mean Squared Error (MSE) function. The crucial for RP estimation is to ensure stable initial least-squares (LS) estimates to replace the unknown quadratic matrix of actual values with the LS covariance matrix. For this purpose, two different data models are proposed, and two research scenarios are formed. Two regularized LS estimations are tested against the non-regularized LS approach. The first one is the classic regularization of LS estimation. In turn, the second one is its iterative counterpart. For the LS estimator of iterative regularization, regularized bias is significantly lower while the overall accuracy is improved in the sense of MSE. The regularized variance-covariance matrix of better precision can mitigate the impact of regularized bias on integer least-squares (ILS) estimation up to some extent. Therefore, iterative LS regularization is well-designed for single-epoch integer ambiguity resolution (AR). Nevertheless, the performance of the ILS estimator is studied in the context of the probability of correct integer AR in the presence of regularized bias.

Objectives

Wilm’s Tumor (WT) is the most common pediatric kidney cancer. Whereas most WTs are isolated, approximately 5% are associated with syndromes such as Denys-Drash (DDS), characterized by early onset nephropathy, disorders of sex development and predisposition to WT.

Case presentation

A 46,XY patient presenting with bilateral WT and genital ambiguity without nephropathy was heterozygous for the novel c.851_854dup variant in WT1 gene sequence. This variant affects the protein generating the frameshift p.(Ser285Argfs*14) that disrupts a nuclear localization signal (NLS) region.

Conclusions

This molecular finding is compatible with the severe scenario regarding the Wilm’s tumor presented by the patient even though nephropathy was absent.

Authors: Arcimavičienė Liudmila , Mastandrea Adam , Snukiškienė Irena , Marčiulionytė Lina , Burbaitė Rūta
Published: March 2022

This study aims to establish ideological effects of the pre-pandemic metaphor use in the mainstream media on users’ perceptions of their relationship with technologies during the COVID-19 pandemic. To achieve that, 120 media articles from global mainstream media sources during the pre-pandemic period were collected and analysed at three levels: (1) metaphor identification; (2) deconstruction of conceptual source domains; (3) the coding of metaphorical expressions into psychological types of interpersonal relationships that are projected on technologies. The established metaphorical patterns were tested in an online survey with 100 young adults and adults from Lithuania during the COVID-19 pandemic period of 2019-2020. The research findings resulted in the ideological perceptions of Reversed Agentivity and Mechanised Action characterising our relationship with technology and pointing out to the loss of individual autonomy, a lack of personal growth and more fragmented personal identity during the pandemic.

The purpose of the present study was to compare differential functioning of Iranian English versus Persian teachers in responding to compliments and to investigate the possibility of sociolinguistic transmission of speech act of responding to compliments from English culture to native Iranian Persian speakers. Following Chen and Yang (2010), we hypothesized that exposure to English would affect the complimenting behavior of Persian speakers, leading to more acceptance of compliments compared to those with little or no exposure to English. Participants of the study were 50 English teachers, regarded as “exposed-to-English” or E group, and 50 Persian teachers, considered as “unexposed-to-English” or U group. The participants’ age ranged from 20 to 35 and they were selected through non-randomized convenience sampling. A Discourse Completion Test (DCT) comprising eight complimenting situations was developed in two versions, i.e. English and Persian, in light of Mane’s (1983) taxonomy. The results revealed a significant difference in performance between groups and that Iranian English teachers’ Compliment Response (CR) behavior changed due to exposure to English and approached English culture. Further findings and implications are discussed in the paper.
Madeiran emigration to South Africa since the 1960s: A sociocultural and linguistic perspective
Authors: Pereira Bruna Micaela Freitas , Nunes Naidea Nunes
Published: March 2022

This article focuses on a study of historical emigration from the 1960s onwards, showing the importance of intercultural interaction. Due to the poverty, hunger and precarious living conditions that existed in Madeira Island, many young people saw emigration to South Africa as a means of escaping a difficult life. Arduous jobs due to their limited qualifications, as well as legal constraints and an inability to understand the language, were just some of the barriers encountered by these emigrants. By interviewing 15 persons from different generations of emigrants (first and second-generation), it was possible to gather information about the reality Madeirans have faced in South Africa. The graphematic transcription of semistructured interviews plays a very important role in the effective recording of these data, guaranteeing their comparability, analysis and discussion. The compilation of the empirical corpus, with the informed consent obtained from the interviewees, respecting their privacy and guaranteeing their anonymity allows us to perform a sociocultural and linguistic study. The study took into account intercultural personal reports of informants coming from different locations of the Island, age groups, genders, and schooling. Even though the impact of the South African culture, language and society was noticeable, the presence of the Portuguese language, music, religion, tradition, and Madeiran food were very strong, due to the fact that the Portuguese community was united.

Surface plasmons, the collective oscillation of electrons, enable the manipulation of optical fields with unprecedented spatial and time resolutions. They are the workhorse of a large set of applications, such as chemical/biological sensors or Raman scattering spectroscopy, to name only a few. In particular, the ultrafast optical response configures one of the most fundamental characteristics of surface plasmons. Thus, the rich physics about photon–electron interactions could be retrieved and studied in detail. The associated plasmon-enhanced electric fields, generated by focusing the surface plasmons far beyond the diffraction limit, allow reaching the strong field regime with relatively low input laser intensities. This is in clear contrast to conventional optical methods, where their intrinsic limitations demand the use of large and costly laser amplifiers, to attain high electric fields, able to manipulate the electron dynamics in the non-linear regime. Moreover, the coherent plasmonic field excited by the optical field inherits an ultrahigh precision that could be properly exploited in, for instance, ultraprecision spectroscopy. In this review, we summarize the research achievements and developments in ultrafast plasmonics over the last decade. We particularly emphasize the strong-field physics aspects and the ultraprecision spectroscopy using optical frequency combs.

Farm productivity in most developing countries remains low, hence the need to enhance technical efficiency (TE) of producers. This study evaluates the TE of maize production in rural Ghana, using primary data from a survey of smallholder producers. A two-stage double bootstrap data envelopment analysis (DEA) approach was used to assess TE and its determinants. The results revealed a bias-corrected mean TE of 68% (as opposed to 81% using the traditional DEA approach). Hence, with the prevailing technology and current input levels, farmers can increase their TE of maize production by 32%. TE increased with adoption of improved varieties, weeding frequency, and herd size but decreased with producer’s age, household size, educational status, and group membership. Subsequently, these factors need to be carefully considered in targeting policies for increasing maize productivity. The study observed increased adoption of improved varieties and training in efficient methods of weed control as important measures to enhance TE of maize farmers.
Determination of shear stresses in the measurement area of a modified wood sample

The purpose of the experiment was to determine the distribution of shear stresses in the measurement area of a natural and modified wood sample. Previous wood shear tests conducted on a typical Iosipescu specimen have shown that a complex stress state exists at the bottom of the notch. With transverse loading of the samples, flexure occurs and normal stresses arise from the bending moment and thus fibers are deformed. For the investigations oriented on shear, shear with stretching, and shear with compression, a special specimen was prepared which differed by notch geometry from a typical Iosipescu specimen. A new test machine is described in the article, which is equipped with special specimen holders to perform investigations in complex stress conditions. Crack patterns recorded for natural and modified wood are presented. For all tests, numerical finite element model simulations were performed to obtain stress distributions inside the specimens. The calculated stress distributions were visualized as contour line projections for natural and modified wood. Transverse shear strength values for the modified Iosipescu sample were found to exceed the magnitude of previously published ASTM D1037-87 test results. The test results proved that the strength properties of anisotropic materials in a complex state of stress can be assessed with great accuracy. This is very important in engineering applications.
Metaphors we are robbed by: a critical discourse analysis of ‘the national cake’ and Nigeria’s prebendal elite
Authors: Bello Umar
Published: March 2022

This paper focuses on aspects of Nigerian corrupt practices and how perceptions of public service and leadership responsibilities are framed linguistically, or discursively, around predatory elitist interests. It is based on two premises. The first pertains to the ways in which the national wealth is metaphorically called the national cake, and how it is viewed as an object that elicits consumption. Textual data is generated from 19 national newspapers and blogs that show 85 occurrences of the term the national cake. The surrounding contexts of the term indicate that national wealth is eatable, shareable and is spatially located. The second premise relates to how the Nigerian elite use metonymic associations to make themselves serve as the aggregate of, or shorthand to, the geographical, partisan and religious interests of the country. This stand-for relationship plays a prominent role in establishing contiguous representations which aid (conceptual) proximity to the national cake. This study uses critical metaphor analysis, corpus linguistics and critical discourse analysis to demystify the facts about Nigeria’s national life otherwise overlaid by ideology.

Darbuotojų pasitikėjimą savimi mažinančių veiksnių valdymas neapibrėžtumo sąlygomis
Authors: Ramašauskienė Virginija
Published: March 2022

Šiame straipsnyje siekiama apibrėžti darbuotojų pasitikėjimą savimi mažinančius veiksnius neapibrėžtumo sąlygomis skirtingą veiklą vykdančiose organizacijose. Atliktas tyrimas trijose Lietuvos verslo organizacijose atskleidė, kad net ir skirtingos darbuotojų pasitikėjimą savimi mažinančios priežastys lemia panašias pasekmes. Nustatyta, kad įtampa, perdegimas, nusivylimas ir kitos darbuotojų savivertės mažėjimo išraiškos tiesiogiai veikia darbuotojų įsitraukimą į organizacijos veiklą ir jos efektyvumą. Darbuotojas nepajėgus atstovauti įmonės interesams, jeigu negeba atstovauti pačiam sau. Būtent pasitikėjimas savimi, kitaip savivertė, yra veiksmingos individo ir organizacijos sąveikos pagrindas. Savivertės mažėjimo priežastis – neapibrėžtumo nulemti savęs atstovavimo apribojimai. Šiandiena tai aktualu visoms organizacijoms, nes visas paveikė užsitęsusi COVID-19 pandemija, globalūs ekonominiai pokyčiai, socialinio bendravimo ir komunikacijos iššūkiai.
