Navigation to Well-being and Work-life Balance for School Principals: Mindfulness-based Approaches
Authors: Kim Dong
Published: March 2022

Objective: The COVID-19 pandemic has posed unanticipated complications for leaders in education. One example involves school principals who have been forced to cope with the pandemic on top of performing their everyday work requirements. In this paper, I review the research on workplace stress and provide suggestions for achieving a good work-life balance based on mindfulness practices, chosen from the experience and added stress of school principals in coping with the unprecedented COVID-19 situation. Methods: I draw upon various sources of information, scientific literature, including more than 130 research journals, empirical studies, and field-based published data to inform the results and conclusion. Results: Various mindfulnessbased practices, which can be done anywhere and in diverse settings, can be valuable options in managing the need for school leaders to achieve emotional and physical equilibrium, an equilibrium to improve their well-being and work-life balance and help to reduce their stress level. Conclusions: To support school leadership and avoid burnout, it is critical that we recognize this increasingly difficult situation and its consequences on them. A nurturing school climate must be established as we commit to advocate for the development of a sound, flexible work-life balance and resilience in education leaders.
Weight Perception and Weight Control Behavior among Florida High School Students
Authors: Pierre Rodrigue , Matthews Kristyn , Tawk Rima
Published: March 2022

Objective: Actions adopted by adolescents to control their weight are motivated by their body weight perception. In this study, we aimed to investigate the association between body weight perception and weight control behavior among Florida public high school students. Methods: We analyzed data from the 2015 Florida Youth Risk Behavior Survey (N = 3798). We used chi-square test to detect group differences among survey respondents and multivariate logistic regression to assess the association between weight perception and weight control behavior. Results: Most survey respondents adopted healthy actions such as exercise and diet, 75.3% and 55.0%, respectively, and few used unhealthy ones as weight control means, such as fasting, use of diet products, and purging, 15.6%, 7.3%, and 6.5% respectively. Compared to respondents who considered themselves as having the right weight, there were higher odds of engaging in healthy activities only in respondents who considered themselves as being overweight while there were higher odds of engaging in unhealthy actions in respondents perceiving themselves as underweight and in those viewing themselves as overweight. Conclusion: High school health education courses should include modules educating students on the importance of having accurate knowledge about body weight and adopting a healthy weight control behavior.

Published: March 2022

Objective: In this study, we estimated the relative contribution of 4 Reasoned Action Approach (RAA) belief determinants in explaining intention to stay home during the COVID-19 pandemic. Methods: Data were obtained from a survey of a nationally representative sample of US adults (N = 942) conducted April 10-20, 2020 (about one-month after initial stay-at-home orders were implemented) using a probability-based Internet household panel (Ipsos KnowledgePanel). Multiple regression analysis tested the association between attitude, injunctive norm, descriptive norm, and self-efficacy and intention to stay home for the next month while controlling for demographic factors. We tested for a moderating effect of worker status on the relationships between the 4 RAA beliefs and intention. Results: Instrumental attitude, injunctive norm, descriptive norm, and self-efficacy demonstrated statistically significant independent associations with intention to stay home. Self-efficacy showed the highest independent association. However, this relation was modified by an interaction between self-efficacy and worker status, revealing that self-efficacy is particularly important for essential workers. Conclusions: These findings suggest that public health strategies to increase individuals’ intention to stay home and encourage adherence to stayat- home policies should focus on enhancing self-efficacy with communication and policy supports. To be most effective, interventions should be targeted based on worker status.

Authors: Antil Harbir , Kubota Shodai , Shirakawa Ken , Yamazaki Noriaki
Published: March 2022

In this article, we consider a class of optimal control problems governed by state equations of Kobayashi-Warren-Carter-type. The control is given by physical temperature. The focus is on problems in dimensions less than or equal to 4. The results are divided into four Main Theorems, concerned with: solvability and parameter dependence of state equations and optimal control problems; the first-order necessary optimality conditions for these regularized optimal control problems. Subsequently, we derive the limiting systems and optimality conditions and study their well-posedness.
A novel similarity measure of link prediction in bipartite social networks based on neighborhood structure
Authors: Sarhangnia Fariba , Mahjoobi Shima , Jamshidi Samaneh
Published: March 2022

Link prediction is one of the methods of social network analysis. Bipartite networks are a type of complex network that can be used to model many natural events. In this study, a novel similarity measure for link prediction in bipartite networks is presented. Due to the fact that classical social network link prediction methods are less efficient and effective for use in bipartite network, it is necessary to use bipartite network-specific methods to solve this problem. The purpose of this study is to provide a centralized and comprehensive method based on the neighborhood structure that performs better than the existing classical methods. The proposed method consists of a combination of criteria based on the neighborhood structure. Here, the classical criteria for link prediction by modifying the bipartite network are defined. These modified criteria constitute the main component of the proposed similarity measure. In addition to low simplicity and complexity, this method has high efficiency. The simulation results show that the proposed method with a superiority of 0.5% over MetaPath, 1.32% over FriendLink, and 1.8% over Katz in thef-measure criterion shows the best performance.
Sophistik, Performanz, Performativ
Authors: Cassin Barbara
Published: March 2022

The present paper discusses the characteristics of performative speech through three distinct but related episodes: 1. the ancient origins of “convincing speech“ in Homeric and Sophistic discourse; 2. the treatment of linguistic issues through speech by South Africa’s Truth and Reconciliation Commission; 3. present-day language as determined and constituted by the plurality of languages, between the Scylla and Charybdis of “Globish” and “ontological nationalism”. John L. Austin’s theory of performative speech acts as laid down in How to do Things With Words serves as a contemporary frame of reference throughout the argument.
Annäherung an Blumenbergs Philosophieverständnis
Authors: Niehues-Pröbsting Heinrich
Published: March 2022

If one compares Hans Blumenberg with the dominant contemporary German-speaking characters of philosophy and heads of their own schools, Husserl, Heidegger and Adorno, then one sees that Blumenberg’s understanding of philosophy proves tobe emphatically unemphatic, withdrawn, and deeply stacked. He exchanges the big bills of those philosophies for small coins: Philosophy is attention first, thoughtfulness second, consolation third, and memory fourth. – An introduction is evidence of the reorientation that Blumenberg undertook in the 1950s with regard to his Catholic-theological and Heideggerian philosophical beginnings. This led him to redefine the modern age from one of crisis to one of overcoming the crisis.
A Study of Knowledge Spillovers within Chinese Mega-Economic Zones
Authors: Huang Xiaobing , Meng Xinxin , Chen Meng
Published: March 2022

Using a prefectural level data, we shed the light on the knowledge spillovers within three mega-economic zones (MEZs) in China by adopting spatial econometric methods. We first examine the spillovers within all regions, and then the spillovers within the MEZs, and finally the spillovers from core cities. The results show that there are pronounced spillovers between cities in China, which is stronger between cities with high techno-proximity. Moreover, spillovers within the MEZs are found to be stronger but unequal. Spillovers between cities in the Pearl River Delta are the greatest among the MEZs, while the spillovers within Jing-jin-ji are the lowest. Eventually, Shenzhen outperforms Shanghai and Beijing in knowledge spillovers, whereas Beijing may even adversely affect the innovation of neighbors.
Lexical and grammatical collocations in beginning and intermediate L2 argumentative essays: a bigram study
Authors: Xia Detong , Chen Yudi , Pae Hye K.
Published: March 2022

Collocations play an important role in L2 learners’ fluent and idiomatic language production. Previous studies using a frequency-based approach to studying collocations underscored the potential to use association measures for distinguishing L2 writing proficiency. However, studies in this line have largely neglected the syntactic relation of words within a collocation. In addition, most L2 collocation studies have focused on learners at upper-intermediate levels and above, leaving the use of collocations by beginner-level learners understudied. Using the Yonsei English Language Corpus, this study investigated frequency (measured by normalized frequency and normalized deviance of proportions), formulaicity (measured by mutual information andt-scores), and diversity (measured by normalized entropy scores) of seven lexical collocations and four grammatical collocations in argumentative essays from beginning to upper-intermediate levels. Results showed that upper-intermediate L2 learners used more collocations with higher association strength and diversity than did beginning-level learners. In addition, collocations used by upper-intermediate learners were more idiomatic and suitable for L2 academic writing. The findings indicated that specific collocational patterns (i.e. adverb-verb and verb-preposition) could serve as reliable indicators of distinguishing beginning L2 writing from upper-intermediate L2 writing.
The search for new stories to live by: A summary of ten ecolinguistics lectures delivered by Arran Stibbe
Authors: Ma Chen , Stibbe Arran
Published: March 2022

This article is a summary of Professor Arran Stibbe’s ten online lectures on ecolinguistics at Beijing Foreign Studies University. The lecture series begins by asking: Why, from an ecolinguistic perspective, do we need new stories to live by? With theoretical insights and practical analyses of a wide range of discourses, it then illustrates how eight types of stories, including ideology, evaluation, erasure, salience, identity, narrative, framing, and metaphor can work cognitively to influence the way people construe reality, in the hope of encouraging people to use language that can inspire them to protect the planet instead of destroying it.
Simulation of pulsed neutron activation for determination of water flow in pipes
Authors: Mattsson H. , Owrang F. , Nordlund A.
Published: March 2022

The effect of the asymmetric distribution of activated water in PNA (pulsed neutron activation) measurements has been investigated experimentally by depositing a small amount of colour, simulating the activated water, in a transparent Plexiglas pipe. Based on the colour experiments, a semi-empirical model has been developed that describes the distribution of the activated water at different distances from the activation point. The model shows that the combination of inhomogeneous activation and a radial velocity profile makes the mean velocity of the activity lower than the mean velocity of the water. It can also be seen that the velocity of the activity increases as the distance from the activation point increases. The model has been compared with experimental values from PNA measurements and the measured mean velocity shows a similar dependence on the distance from the activation point.
Analytical study of flow instability behaviour in a boiling two-phase natural circulation loop under low quality conditions
Authors: Nayak A. K. , Kumar N. , Vijayan P. K. , Saha D. , Sinha R. K.
Published: March 2022

Analytical investigations have been carried out to study the flow instability behaviour in a boiling two-phase natural circulation loop under low quality conditions. For this purpose, the computer code TINFLO-S has been developed. The code solves the conservation equations of mass, momentum and energy and equation of state for homogeneous equilibrium two-phase flow using linear analytical technique. The results of the code have been validated with the experimental data of the loop for both the steady state and stability. The study reveals that the stability behaviour of low quality flow oscillations is different from that of the high quality flow oscillations. The instability reduces with increase in power and throttling at the inlet of the heater. The instability first increases and then reduces with increase in pressure at any subcooling. The effects of diameter of riser pipe, heater and the height of the riser on this instability are also investigated.
Alerting procedures for scenarios without warning times
Authors: Baggenstos M.
Published: March 2022

For purposes of emergency planning for Swiss nuclear power plants the following scenarios were selected from among a great variety of possible sequences: scenarios without core damage, scenarios with core damage and correct functioning of the containment and the filtered venting system, and scenarios with core damage and without correct functioning of the containment – medium up to long pre-phase. The selection of these scenarios serves as basis for establishing measures to protect the population. This contribution presents alerting procedures for scenarios without warning time.
Conative calls to animals: From Arusa Maasai to a cross-linguistic prototype
Authors: Andrason Alexander , Karani Michael
Published: March 2022

Abstracct

The present article expands our empirical and theoretical knowledge of conative animal calls (CACs) in the languages of the world. By drawing on canonical typology and prototype theory – and by contrasting the original evidence related to the category of CACs in Arusa Maasai with the evidence concerning CACs in other languages that is currently available in scholarship – the authors design a cross-linguistic prototype of a CAC and enumerate its 18 prototypical non-formal (semantic-pragmatic) and formal (phonetic, morphological, and syntactic) features.
Bankers communicating wrongdoing and failure: Apologies or apologetics?
Authors: Breeze Ruth
Published: March 2022

This paper analyses letters to shareholders by bank presidents in the ten years after the financial crisis to establish whether apologies for corporate wrongdoing and mismanagement are present, and if not, how these negative aspects are communicated. Apologies and quasi apologies are shown to be part of a wider repertoire of strategies including alignment with those affected, disassociation from negative events, scapegoating of perpetrators, and promises of future good conduct. These findings are discussed in terms of the banks’ ongoing relationship with shareholders, and their wider reputation management endeavours.
Anti-Chinese sentiment in the Czech public service media during the COVID-19 pandemic
Authors: Sedláková Renáta
Published: March 2022

This paper focuses on Sinophobia which is usually not expressed openly in the public service media. The Sinophobia discourse intensified in 2020 in connection with the coverage of the pandemic. How are anti-Chinese attitudes expressed in the news discourse of the Czech Radio and Czech Television? Examples from a broader analysis of the representation of the SARS-COV-2 pandemic in news and journalism programmes are given. Inductive qualitative research methods (discourse and semiotic analysis) were used to detect subtle nuances of meaning and reveal implicit presuppositions. This study focuses on the manifestations of bias, e.g., the ideologically grounded attitudes of the speakers. The anti-Chinese statements (about poor hygiene habits and eating wild animals) were most often mentioned in connection with the origin of the coronavirus, vaccination, and China expansive policy. Sinophobic messages were built on the opposition of Us and Them, which is, according to van Dijk (2000), the core of new racism. In spite of the fact that the open hate speech and systematic bias (intentional implications, obvious evaluation or signposting) were not found in the researched sample, the analysis identified the presence of Sinophobic statements in both public service media.
Metaphor in the written discourse of Arab students at a College of Education in Israel
Authors: Shakkour Aadel , Qasim Nader
Published: March 2022

This article shows how Arab students at an Arab college in Israel, majoring in teaching of mathematics, English, and science, rely on metaphor as an important rhetorical tool for the advancement of their ideological positions and for criticism of the policies of the Israeli government, which discriminates against and disenfranchises Arab Israelis. The underlying hypothesis of the article is that the way Arab students in Israel use metaphor in their writing has unique rhetorical aspects that help to sharpen their message in pursuit of the broader goal of emphasizing Arab Israelis’ suffering and changing for the better the Israeli government’s discriminatory patterns of action against them.
ZPD-based mediation of L2 learners’ comprehension of implicatures: An educational praxis framework
Authors: Mirzaei Azizullah , Naseri Farshad , Jafarpour Aliakbar , Eslami Zohreh
Published: March 2022

Conversational implicatures (CIMs) are implied by the speaker in context rather than being linguistically encoded, and learners’ inability to infer the intended meaning, if not remedied through instruction (or mediation), leads to communication breakdowns. Given this premise, the current study aimed to examine effects of classroom praxis-based instruction adjusted to EFL learners’ Zone of Proximal Development (ZPD) on their comprehension of CIMs. Participants were 36 Iranian high school students in 2 classrooms, assigned to experimental and comparison groups. A 20-item CIM test was administered at pretest and posttest times to collect the data. Microgenetic trajectories were also traced through audio-recorded role-plays and social interactions within the ZPD setting. ZPD-adjusted mediational instruction on CIMs was given based on a multi-level regulatory scale and a view of microgenetic development along an other-to self-regulated functioning continuum. In the non-ZPD setting, mainstream teacher-fronted instruction was employed. ANCOVA results revealed differential instructional effects in favor of the praxis-based mediational setting. Microgenetic learning episodes also portrayed how collectively-mediated, ZPD-activated learning led to L2 learners’ progressively improved comprehension of CIMs. The findings suggest that comprehension (and perhaps production) of L2 CIMs can be improved through praxis-oriented co-construction of pragmatic knowledge through collaborative engagement with communicative activity.

Narrowband diffuse thermal emitter based on surface phonon polaritons
Authors: Ma Binze , Huang Yun , Zha Weiyi , Qin Bing , Qin Rui , Ghosh Pintu , Kaur Sandeep , Qiu Min , Li Qiang
Published: March 2022

Thermal emission engineering with ability to realize spectral and spatial selection has attracted great attention in recent years. Nanophotonic control of thermal radiation has demonstrated narrowband thermal emitter but with high angle-sensitivity and diffuse thermal emitter but with low quality factor (Q). Here, we demonstrate a simultaneous narrowband, diffuse thermal emitter consisting of 80 nm (<λ/100) thick Ge nanostructures on a silicon carbide (SiC) phononic material. Based on surface phonon polaritons, a spectral coherent emission with a high Q factor of 101 is achieved at ∼10.9 μm wavelength in experiment. Furthermore, this phonon-mediated nanostructure provides spatial control with strong diffuse thermal emission with a full angle at half maximum of 70°. Additionally, the emission wavelength and intensity are tuned by replacing Ge with phase change materials (Ge2Sb2Te5 and In3SbTe2). The designed narrowband diffuse thermal emitter offers new perspectives for the engineering of emission and paves the way for infrared applications, including thermal sources, radiative cooling, infrared sensing, and thermal photovoltaics.
Evaluation of 11 potential trap crops for root-knot nematode (RKN) control under glasshouse conditions
Authors: Samara Rana
Published: March 2022

A preliminary study of the development and growth of lettuce crops trap cropped with 11 trap crops for root-knot nematode (RKN) control was studied under glasshouse conditions in Kadoorie Agriculture Research Centre in Palestine Technical University. Main crop growth parameters were evaluated by measuring the shoot height, lateral root length, wet and dry weight, ash percentage, and chlorophyll content. The total RKNs recovered from both main and trap crops from root systems were counted 6 weeks post RKN artificial inoculation. The first screening of the potential trap crops against RKNs showed a significant reduction in nematode numbers in lettuce and the average number of galls per gram fresh root when trap cropped with canola, B.G. pumpkin, mustard, and vetch cv. 976. No eggs were found by the end of the experiment. These trap crops attracted more nematodes and kept them from infecting the main crop. The effect of these trap crops on the growth and development of the main crop was variable. Trap cropping lettuce with canola, mustard, Armenian cucumber, and bottle gourd pumpkin caused a significant reduction of the total wet weight and dry weight compared with the control. Still, trap cropping did not significantly affect the lateral root length and wet weight. Removing the trap crops from the field after 6–8 weeks could be applied to reduce the competition between the main crop and the trap crops.
Electroosmotic flow for Eyring fluid with Navier slip boundary condition under high zeta potential in a parallel microchannel
Authors: Zhang Tiange , Ren Meirong , Cui Jifeng , Chen Xiaogang , Wang Yidan
Published: March 2022

The electroosmotic flow of non-Newtonian fluid–Eyring fluid in microparallel pipes under high zeta potential driven by the combination of pressure and electric force is studied. Without using the Debye–Hückel (DH) linear approximation, the numerical solutions of the fluid potential distribution and velocity distribution obtained using the finite difference method are compared with the analytical approximate solutions obtained using the DH linear approximation. The results show that the numerical method in this article is effectively reliable. In addition, the influence of various physical parameters on the electroosmotic flow is discussed in detail, and it is obtained that the velocity distribution of the Eyring fluid increases with the increase in the electric potential under the high zeta potential.
Refusing invitations and offers in second language Chinese: effect of proficiency at the actional and interactional levels
Authors: Su Yunwen
Published: March 2022

The present study investigates the role of proficiency in the development of second language (L2) Chinese learners’ ability to negotiate refusals of invitations and offers in conversational interactions. Fifty-four American English learners of L2 Mandarin Chinese at three proficiency levels, and 22 native speakers, completed a four-item naturalized roleplay task. Findings suggest positive effects of proficiency on L1 American English L2 Chinese learners’ production of refusals at both actional and interactional levels, though different aspects of their pragmatic competence may not develop in parallel. NSs and learners across proficiency levels had access to a similar range of refusal strategies, but learner production showed a more target-like context-specific combination of refusal strategies with increasing proficiency. The effect of proficiency can also be observed on learners’ acquisition of sequential organization of refusals, in terms of delay and discourse patterns, in various context. Nevertheless, it is still unclear at what point along the developmental trajectory learners are sociopragmatically competent enough to show consistent orientation towards the hearer in their refusals as NSs do.
Unique transport behaviour of Am(III)/Eu(III) ions across a supported liquid membrane containing a TREN-based diglycolamide dendrimer ligand
Authors: Mahanty Bholanath , Verma Parveen K. , Mohapatra Prasanta K. , Leoncini Andrea , Huskens Jurriaan , Verboom Willem
Published: March 2022

Appropriately functionalized dendrimers are exotic ligands and are expected to give rise to better extraction/transport results than the corresponding monofunctional ones. Diglycolamide- (DGA) based dendrimers and their transport studies are rarely reported. Transport of Am(III) and Eu(III) was studied across a PTFE- (polytetrafluoroethylene) based flat sheet supported liquid membrane containing a tris(2-aminoethyl)amine (TREN) dendrimer ligand containing six DGA pendent arms (termed as TREN-G1-DGA) in 5% isodecanol modified n-dodecane. The transport results were compared with those of the monofunctional ligand TODGA (N,N,N′,N′-tetra-n-octyl diglycolamide). In case of a 5.75 × 10−4 M TREN-G1-DGA solution, Am(III) transport was slower than that of Eu(III) under identical conditions. In case of TREN-G1-DGA the role of acid on the metal ion transport was less important than that while using TODGA as a carrier. However, a nitric acid medium is much more suitable for metal ion transport than a mixture containing sodium nitrate as the major component. Insight into the extraction and transport of the Eu(III) complexes was obtained from luminescence spectroscopic studies.
Normal development of the brain: a survey of joint structural–functional brain studies
Authors: Namiranian Roxana , Rahimi Malakshan Sahar , Abrishami Moghaddam Hamid , Khadem Ali , Jafari Reza
Published: March 2022

Joint structural–functional (S-F) developmental studies present a novel approach to address the complex neuroscience questions on how the human brain works and how it matures. Joint S-F biomarkers have the inherent potential to model effectively the brain’s maturation, fill the information gap in temporal brain atlases, and demonstrate how the brain’s performance matures during the lifespan. This review presents the current state of knowledge on heterochronous and heterogeneous development of S-F links during the maturation period. The S-F relationship has been investigated in early-matured unimodal and prolonged-matured transmodal regions of the brain using a variety of structural and functional biomarkers and data acquisition modalities. Joint S-F unimodal studies have employed auditory and visual stimuli, while the main focus of joint S-F transmodal studies has been resting-state and cognitive experiments. However, nonsignificant associations between some structural and functional biomarkers and their maturation show that designing and developing effective S-F biomarkers is still a challenge in the field. Maturational characteristics of brain asymmetries have been poorly investigated by the joint S-F studies, and the results were partially inconsistent with previous nonjoint ones. The inherent complexity of the brain performance can be modeled using multifactorial and nonlinear techniques as promising methods to simulate the impact of age on S-F relations considering their analysis challenges.

Published: March 2022

The second and third order elastic constants (SOECs and TOECs) of 4d-transition metal mononitrides XN (X: Zr and Nb) have been computed in the temperature range 0 K–500 K using Coulomb and Born–Mayer potential up to second nearest neighbours. In order to investigate the mechanical stability of XN, the computed values of SOECs have been utilized to find out Young’s modulus, bulk modulus, shear modulus, Zener anisotropy and Poisson’s ratio. Furthermore, the SOECs are applied to compute the wave velocities for shear and longitudinal modes of propagation along ⟨100⟩, ⟨110⟩ and ⟨111⟩ crystallographic orientations in the temperature range 100 K–500 K. Temperature dependent Debye average velocity, ultrasonic Grüneisen parameters (UGPs) and Debye temperature have been evaluated. In present work the thermal conductivity of chosen materials has also been evaluated using Morelli-Slack’s approach. Specific heat and total internal thermal energy have been calculated in the temperature range 100 K–500 K on the basis of Debye theory. Thermal relaxation time, acoustic coupling constants and attenuation of ultrasonic waves due to thermo-elastic relaxation and phonon–phonon interaction mechanisms have been calculated in the temperature range 100 K–500 K. The obtained results of present investigation have been compared with available other similar type of materials.

Published: March 2022

The synthesis of bis(diphenylphosphino)ethane (dppe) and PMe3 mono-adducts [(dppe)BeCl2]n and [(PMe3)BeCl2]2 is described and their spectroscopic properties discussed. Hydrolysis of these two compounds and of the bis(diphenylphosphino)propane (dppp) adduct to BeCl2 gave [dppeH2][BeCl4], [Me3PH]n[Be4Cl9]n and [dpppH2][Be2Cl6], which have been isolated and structurally characterized by single crystal X-ray diffraction. The reactions of [(PMe3)BeCl2]2 with p-cresole gave [Me3PH]2[Be2Cl4(OC7H7)2]. This phenoxide together with [(Me3PO)2Be2Cl4], the oxidation product of [(PMe3)BeCl2]2, have also been structurally characterized.
Whole transcriptome analysis of breast tumors during neoadjuvant chemotherapy: association with response to preoperative chemotherapy
Authors: Ibragimova M. K. , Tsyganov M. M. , Litviakov N. V.
Published: March 2022

Introduction. Treatment of breast cancer often includes systemic neoadjuvant chemotherapy. The frequency of complete morphological response varies significantly depending on the molecular subtype of tumor. However, even in triple negative breast cancer, which is considered the most sensitive, it does not exceed 50 %. Therefore, the search for new genetic predictors of tumor response to preoperative treatment, as well as the assessment of tumor changes during neoadjuvant chemotherapy are highly relevant.Objective – to perform whole-transcriptome analysis of breast cancer during neoadjuvant chemotherapy depending on tumor response to preoperative treatment.Materials and methods. This study included 39 patients with luminal B HER2-positive (human epidermal growth factor receptor 2) breast cancer who received 6 to 8 cycles of neoadjuvant chemotherapy. We performed whole-transcriptome analysis of paired biopsy and surgical specimens using the Clariom™ S Assay, human (Affymetrix, USA).Results. We observed significant differences in the pretreatment expression of 166 genes (13 were up-regulated and 153 were down-regulated) between patients with objective response to therapy and those without it. Comparison of preand post-treatment expression profiles demonstrated 680 differentially expressed genes in patients with complete and partial response and 3240 differentially expressed genes in patients with stable or progressive disease. Venn diagram showed that patients with and without objective response to neoadjuvant chemotherapy shared 105 differentially expressed genes.Conclusion. We performed primary screening of genes in breast tumors before therapy and identified genes whose pretreatment expression differed significantly between patients with objective response to neoadjuvant chemotherapy and those without it. Further validation of these genes in an independent sample will allow the development of a genetic panel to evaluate the response to neoadjuvant chemotherapy. Assessment of changes in the expression of tumor genes during treatment depending on patient’s response to therapy can be useful for further development of a panel of genes, which will enable the evaluation of clinical response to chemotherapy, as well as identification of key cellular processes that change the activity of genes during therapy.

Published: March 2022

Introduction. Uveal melanoma ability to metastasize depends on a few prognostic factors. The genetic ones are considered to be the most significant. The role of disorders of the short arm of chromosome 8 (8p), as well as a combination of changes in 8p and the long arm of this chromosome (8q) in the development of metastatic lesions in this pathology remains insufficiently studied.The study objective – to evaluate the prognostic value of chromosome 8 abnormalities in patients with uveal melanoma.Materials and methods. We analyzed 2 retrospective groups of patients who underwent enucleation for uveal melanoma, statistically homogeneous in the main clinical parameters. Group 1 included patients without signs of metastases (n = 41) with an average follow-up period of 71 months, Group 2 included patients with detected metastases (n = 51) and an average follow-up period of 21 months Chromosome abnormalities were tested by multiplex ligation-dependent probe amplification.Results. Three- and five-year survival in patients with uveal melanoma without 8p deletion were 64 and 54 %, respectively; with 8p deletion significantly lower – 25 and 6 %, respectively. The same survival rates in patients with uveal melanoma with 8q amplification were 43 and 26 %, respectively, whereas in patients without 8q amplification they were significantly higher – 80 and 74 %, respectively. In patients with uveal melanoma harbouring both abnormalities, 3- and 5-year survival rates were 26 and 7 %, whereas isolated 8q amplification was associated with 47 and 35 % survival, respectively. These survival rates differ greatly and significantly: hazard ratio 3,26 (95 % confidence interval 1,86–5,69) and 6,89 (95 % confidence interval 2,67–17,73), respectively (р <0,0001).Conclusion. The findings support comprehensive evaluation of chromosome 8 abnormalities as a substantial part of uveal melanoma prognostication. 8q amplification, 8p deletion, combination of these abnormalities and its role in uveal melanoma malignity should be further discovered. Further research in this direction is needed.

Bu araştırmada, okul öncesi öğretmen adaylarının pandemi süreci boyunca uzaktan yürütülen müzik eğitimi dersine yönelik öğrenci tutumlarının belirlenmesi, öğrenci görüşleri doğrultusunda uzaktan eğitimin olumlu ve olumsuz yönlerinin ve yaşanan sorunların ortaya çıkarılması amaçlanmıştır Araştırmanın çalışma gurubunu, 2020-2021 eğitim öğretim yılı bahar döneminde “Erken Çocuklukta Müzik Eğitimi” dersini alan ve Ziya Gökalp Eğitim Fakültesi Okul Öncesi Öğretmenliği Bölümünde öğrenim görmekte olan toplamda 42 öğrenci oluşturmaktadır. Araştırmada karma yöntem kullanılmıştır. Araştırmanın nicel boyutunda öğretmen adaylarının tutumlarının belirlenmesi amacıyla, Ağır, Gür ve Okçu (2008) tarafında geliştirilen “Uzaktan Eğitime Yönelik Tutum Ölçeği” kullanılmıştır. Araştırmanın nitel boyutunda ise araştırmacı tarafından hazırlanan yarı yapılandırılmış görüşme formu kullanılmıştır. Araştırmadan elde edilen nicel veriler SPSS 22.0 paket program kullanılarak analiz edilmiştir. Araştırmanın nitel verilerinin analizinde ise içerik analizi kullanılmıştır. Araştırmanın sonucunda; okul öncesi öğretmen adaylarının uzaktan müzik eğitimi dersine yönelik tutumlarının orta düzeyde olduğu ve tutum puanlarının cinsiyet değişkenine göre anlamlı bir farklılık oluşturmadığı saptanmıştır. Öğrenciler uzaktan eğitim sürecinde uygulama yapılamaması, etkileşimin sınırlı olması ve verimin düşük olması gibi olumsuz yönde görüş bildirmişlerdir. Bilgiye ulaşmanın kolay olması ve zaman-mekân kısıtlamasının olmaması ise olumlu olarak görülmüştür. Ayrıca, kullanılan uzaktan eğitim sisteminin yetersizliği ve İnternetle ilgili sorunlardan söz edilmiş ve uzaktan müzik eğitiminin derse olan motivasyonu olumsuz yönde etkilediği belirtilmiştir.
Digitization in Agriculture: A Timely Challenge for Ecological Perspectives
Authors: Adusumalli Harshini Priya
Published: March 2022

The main focus of political debates on digital agriculture has been on environmental sustainability. So far, the literature has primarily ignored social sustainability, notably labor issues. This is worrisome because digitization may fundamentally alter farming techniques and labor processes, potentially affecting rural development, rural communities, and migratory workers. It examines how digital technology affects labor in horticulture and agricultural fields. To incorporate labor into the debates around agriculture and digitalization, this article provides a detailed picture of how digital technologies affect agricultural labor. Results suggest new forms of labor management, intensification of work processes, and risks of working-class fragmentation along age lines. Digitalization has not resulted in worker or farmer deskilling. The claim of greater worker dependency due to reduced agricultural employment possibilities is disputed. The importance of creating agricultural policies that promote fair and equitable working conditions.
SOSYOLOJİNİN PENCERELERİ, PENCERELERDEN SOSYOLOJİ: PANDEMİ SÜRECİNDE İSTANBUL’DA SOSYAL KIRILGANLIK VE ÇOKLU-AFET ÜZERİNE NİTEL ARAŞTIRMA DENEYİMİ

Pandemi deneyimleri; toplumsal cinsiyet, yaş, etnisite, sosyo-ekonomik seviye gibi etkenlere bağlı olarak değişmekte ve derinleşmektedir. COVID-19 pandemisi ve fiziksel mesafe tedbirleri ise bu süreçte yürütülen sosyal araştırmalar için önemli sınırlılıklar doğurmuştur. Bu sınırlılıkları aşmak için araştırmacılar tarafından geliştirilen stratejilerin gelecek araştırmalar için sağlayabileceği yeni olanaklar da tartışılmaktadır. Bu makale, pandeminin erken döneminde İstanbul ilinde sosyal kırılganlık ve çoklu-afet kapsamında gerçekleştirilmiş iki saha araştırmasına dayanarak, bu süreçte çevrimiçi nitel araştırma yapmanın olanak ve sınırlılıklarını, yöntemsel çerçevesini ve özgün dinamiklerini ele almaktadır. Birinci araştırma kapsamında, İstanbul ilinin farklı sosyal kırılganlık seviyelerine sahip dört ilçesinin farklı mahallelerinde görev yapan 20 muhtarla görüşmeler gerçekleştirilmiştir. İkinci araştırma kapsamında ise İstanbul’un Sancaktepe ilçesinin sekiz mahallesinden sosyal kırılganlık statüsünü karşılayan 20 kişiyle görüşülmüştür. Her iki araştırmada da yarı-yapılandırılmış çevrimiçi görüşmeler gerçekleştirilmiş ve Google Haritalar Sokak Görünümü uygulamasından yararlanılmıştır. Pandemi sürecinde bu özgün koşullarda oluşan sınırlılıklar ve bu sınırlılıkları aşma stratejileri; örneklem tasarımı ve örnekleme erişim, zaman ve maliyet, araştırmacı-katılımcı arasındaki mesafe ve etik sorunlar, değişen mekân ve saha kavramı başlıklarıyla ele alınmıştır. Son olarak, bu çalışma kapsamında elde edilen tecrübelerin gelecek araştırmalar içindeki konumu tartışılmış; dijital pencerelerden yapılan sosyolojinin, sosyoloji disiplini içerisinde açabileceği pencereler üzerinde durulmuştur.

Bu makalede, COVID-19 pandemisi sürecinde nitel araştırma yöntemiyle gerçekleştirilmiş sosyolojik bir araştırmanın, araştırma tasarımı sürecine ve üç ay süren saha çalışması deneyimlerine yer verilecektir. Makaleye konu olan araştırmada, çok mevkili saha araştırması yöntemi kullanarak Gaziantep (Suriyeli), Muğla (yerli ve Britanyalı) ve Zonguldak (yerli) olmak üzere üç farklı ilde yalnız yaşayan yaşlı kadınlarla Ağustos 2020-Ekim 2020 tarihleri arasında yüz yüze derinlemesine görüşmeler yapılmıştır. Pandemi koşulları, araştırma sahasının, saha çalışmasını yürütecek araştırmacıların ve araştırma yönteminin belirlenmesinde ve saha çalışmasının planlanmasında, başka deyişle araştırma tasarımı sürecinde belirleyici olurken; araştırmanın başlangıcından tamamlanmasına kadar olan tüm aşamalarda öngörülemeyen durumlarla karşılaşılmasına da neden olmuştur. Katılımcılara erişim imkânlarının daralması ve araştırmacı-katılımcı-aracı arasındaki güven tesisinin zorlaşması öngörülemeyen durumların başında gelmektedir. Bunun karşısında araştırmacılar, araştırmanın bütününe yayılan risk yönetimi çerçevesinde, zorluklar karşısında çeşitli stratejiler geliştirmiştir. Görüşmelerin tek seferlik ve uzun süreli planlanması ile kartopu tekniğinin çalışmaması ve kurumsal aracıların çoğu durumda işlevsiz kalması karşısında mahalli aracıların çeşitlendirilmesi bu stratejilerden bazılarıdır. Makalede, pandemi döneminde gerçekleştirilen bir araştırmada hâlihazırda mevcut eşitsizlik ve kırılganlıkların salt katılımcılardan elde edilen verilerle sınırlı kalmadığı, bunların araştırmacıların saha deneyimlerine de yansıyan belirleyiciler olduğu ortaya konmaktadır.

COVID-19 pandemisi, dünya çapında toplumları ve toplulukları etkileyen önemli bir eşik ve kırılma noktası olmuştur. Bu çalışmanın amacı küresel bir kriz olarak yaşanan pandeminin bireyin gündelik hayatına dair etkilerini anlamaktır. Özellikle gençler üzerine odaklanan araştırmanın genel çerçevesi yaşanan değişimin üç farklı dönemde boylamsal olarak incelenmesine dayanır. Bu makale ise araştırmanın ikinci dönemi olarak belirlenen Mayıs-Temmuz 2021 yılında sürdürülen ve nitel verilerin elde edilmesine dayanan dönemi kapsar. Pandeminin neden olduğu en belirgin etki olarak makine/araç etrafında yeniden kurgulanan “yeni” toplumsallıkların ve yaşam biçimlerinin varlığıdır. Bu durum insan sonrası yaklaşımlar çerçevesinde minör bilim ve yeni materyalizm kavramları ile tartışılmış ve açıklanmaya çalışılmıştır. Yaşanan pandemi krizi, makro sistemlerden gündelik hayat pratiklerine kadar birçok alanda kırılganlıklara neden olmuştur. Bir diğer önemli kırılganlık etkisi ise sosyal bilimsel çalışmalarda yaşanmıştır. Çalışmanın bir diğer tartışılan odak noktası ise kriz anlarında sosyal bilimsel çalışmaların nasıl sürdürüleceğine dair temel sorunsaldır. Bu nedenle sosyal bilimlerin pandemide araştırma yapmanın zorlukları ve imkanları da deneyimlenen bir araştırma pratiği olarak sunulmuştur.
