Learning to Teach in Place: Transforming Pre-service Teacher Perceptions of Science Teaching Through Place Pedagogies
Authors:   Federation University Australia, Ma Hongming
Published: August 2021

Although teaching science outdoors is well established in global circles, its pedagogical value in Australia is less understood. This paper addresses this gap through its investigation of outdoor science teaching in a science method course in a teacher education program at an Australian regional university. As part of their coursework, pre-service teachers designed and delivered science lessons to primary school-aged children in small teaching groups in a wetland setting and wrote reflective essays about the experience. Data collection methods included document analysis of the essays as well as follow-up semi-structured interviews with pre-service teachers. Findings suggest that the outdoor science teaching experience improved pre-service teachers’ general science teaching skills, and significantly contributed to their capacity to teach science outdoors. Considerations regarding how teacher education curriculum and pedagogy can be reconfigured to better equip graduating teachers with the relevant science skills,
Creating Greater Awareness of the Australian Professional Standards for Teachers in Initial Teacher Education
Authors:   Australian Catholic University, Cain Melissa , Campbell Chris ,   Griffith University - Australia
Published: August 2021

Throughout their initial teacher education training in Australia, students are informed about the Australian Professional Standards for Teachers (APST) and the necessity of gathering evidence to achieve these for teacher registration. Whilst the use of digital technologies as tools for reflection has become increasingly popular, there remains a paucity of research around the types of digital technologies that students use to document their ability to achieve accreditation requirements. This study presents details of how PebblePad, a specialised ePortfolio platform, can assist teacher education students to gain increased awareness about the 37 APST descriptors through the use of tagging. Results demonstrate that students found tagging an invaluable practice and that they recognised the importance of using this ePortfolio platform after graduation to build on their growth as educators in alignment with the APST. In this way, the study addresses a significant gap in teacher education literature in this era of accountability.
Conversations with Australian Teachers and School Leaders About Using Differentiated Instruction in A Mainstream Secondary School
Authors:   Griffith University, Gibbs Kathryn , Beamish Wendy ,   Griffith University
Published: August 2021

Circumstances in today’s schools are requiring a rethinking of pedagogical approaches so that equitable learning opportunities are provided to all students. This small-scale, qualitative Australian study reports how some teachers and school leaders viewed differentiated instruction (DI) being applied in their secondary campus to address diverse abilities and needs. Individual semi-structured interviews were conducted using Zoom. The analysis of data identified three themes related to DI: understandings, practices, and concerns. Findings showed that all participants understood many of the important elements of DI. Teachers reported using several well-known DI strategies, with experienced teachers applying a more considered approach. Teachers raised concerns about limited time for planning and instruction while school leaders expressed concerns about the adjustment of assessment tasks and feedback on progress to individual students. These findings provide starting points for more in-depth investigations at secondary schools. Implications linked to teacher preparation and administrative support in schools are presented.
The eﬀect of nickel phytotoxicity on photosystem II activity and antioxidant enzymes in barley
Authors: Doğru Ali , Altundağ Hüseyin , Dündar Mustafa Şahin
Published: August 2021

In this study, the eﬀect of mild (100 µM), moderate (300 µM) and severe (500 µM) nickel (NiSO4.7H2O) toxicity on the photosynthetic activity, photosynthetic pigment content and some antioxidant enzymes in the leaves of a barley cultivars (Hordeum vulgare L. cv. Tarm-92) was investigated. Moderate and severe nickel toxicity decreased root length while shoot length was not aﬀected by nickel stress, probably due to over accumulation of nickel in roots. Similarly, biomass accumulation was declined by moderate and severe nickel toxicity as reﬂected by the lowered fresh and dry weight. Chlorophyll a, chlorophyll b and consequently total chlorophyll content decreased by all nickel applications, presumably because the reduced level of carotenoids. Chlorophyll a ﬂuorescence measurements showed that nickel toxicity blocked electron movement in some speciﬁc points of the photosynthetic electron transport system. The constant Fo value indicated that PSII reaction centers was not damaged in the leaves of barley under nickel toxicity while the reduced Fm value showed that acceptor side of PSII was more sensitive to nickel toxicity as compared to donor side. Changes in JIP test parameters in the leaves of barley showed that primary photochemical reactions are reduced, and thermal dissipation of excess energy is increased. SOD and CAT activity is elevated in the leaves of barley under moderate and severe nickel toxicity which demonstrate an eﬃcient superoxide dismutation. Severe nickel toxicity, however, did not aﬀect SOD and CAT activity. The ascorbate-glutathione cycle was activated in the leaves of barley plants under nickel toxicity, probably indicating an eﬃcient H2O2 detoxiﬁcation. However, considerable H2O2 and MDA accumulation was observed in the leaves of barley under nickel stress. As a result, it may be concluded that the barley genotype Tarm-92 is moderately tolerant to nickel toxicity.
TU-DAMD employment for molecular characterization of Salvia judaica and Salvia palaestina species
Authors: Saleh Basel
Published: August 2021

Genetic diversity in perennial Salvia judaica Boiss (Judean sage) and Salvia palaestina Benth (Palestinian sage) species using touch-up directed amplification of minisatellite region DNA (TU-DAMD) has been performed in two separated sets; in the first set (set A) the initial annealing temperature was increased from 50 °C to 55 °C, whereas, in the second one (set B), it increased from 55 °C to 60 °C by 0.5 °C/cycle during the first 10 PCR amplification cycles. Fifteen DAMD primers have been tested for each set. Set (A) produced 89.39% polymorphism level (P%) with polymorphic information content (PIC) average of 0.33 and marker index (MI) average of 3.96. Whereas, in set (B) these values were recorded to be 94.02%, 0.34 and 3.98 for P%, PIC and MI, respectively. Data showed that the two mentioned sets successfully highlighted high polymorphism level between the two studied Salvia sp. This work studies genetic diversity of S. judaica and S. palaestina species using TU-DAMD test as a novel molecular marker.

Published: August 2021

Our aim was to map the gut region-specific diﬀerences of the mucosa-associated microbiome distribution in a streptozotocin-induced diabetic rat model. Tissue samples from the duodenum, ileum and colon were collected 10 weeks after the onset of hyperglycaemia to analyse the mucosa-associated microbiota using next-generation DNA sequencing. Striking diﬀerences were observed in the mucosa-associated microbiota of the duodenum between diabetic and control rats. A significant invasion of the aerobic genus Mycoplasma was apparent in diabetes, and the abundance of the anaerobic phylum Firmicutes decreased massively. It is noteworthy that insulin treatment eliminated the Mycoplasma invasion in the duodenum and apparently restored the anaerobic environment in the mucosa. In the ileum the abundance of the phylum Firmicutes increased in the diabetic samples. Although the proportion of the phylum Proteobacteria decreased moderately, its composition changed significantly, and insulin treatment induced only minor alterations. In the diabetic samples of colon, the abundance of the phylum Firmicutes decreased slightly, the relative number of the bacteria in the phylum Bacteroidetes increased strongly as compared to the control values, and after insulin treatment this increase was more significant. Chronic hyperglycaemia has the most prominent eﬀect on the mucosa-associated microbiota in the duodenum.

Published: August 2021

Acinetobacter baumannii (A. baumannii) is an important nosocomial pathogen, which may be a causative agent in a wide-range of human pathologies. Carbapenems are usually considered the last safe and eﬀective choice of drugs for the treatment of Gram-negative infections. The emergence of carbapenem-resistant A. baumannii (CRAB) is a critical public health issue as they leave clinicians with limited therapeutic options. In this study, phenotypic methods were used to characterize sixty-two (n = 62) A. baumannii isolates, which were included based on their suspected non-susceptibility to meropenem. Minimum inhibitory concentrations (MICs) of meropenem, levofloxacin, gentamicin, sulfamethoxazole/trimethoprim, tigecycline were determined using E-tests, while colistin MICs were determined using broth microdilution. The isolates were subjected to the modiﬁed Hodge test (MHT), the modiﬁed carbapenem-inactivation method (mCIM) and the imipenem/EDTA combined disk test (CDT). Eﬄux pump overexpression was studied using agar plates containing phenylalanine-arginine β-naphthylamide (PAβN). Assessment of bioﬁlm-formation was carried out using the crystal violet tube-adherence method. 64.5% of the strains showed meropenem MICs in the resistant range (>8 mg/L), resistance rates were similarly high to the other tested antibiotics. The MHT and mCIM assay were positive in 79.0% and 67.7% of cases, respectively; the presence of an MBL was suggested for 29.0% of isolates. Eﬄux-pump overexpression was seen in 12.9% of isolates. 54.8% of the isolates were characterized as strong bioﬁlm-producers. Microbiology laboratories have an important role in diﬀerentiating the distinct mechanisms by which these pathogens develop the CRAB phenotype, as plasmid-borne carbapenemases are signiﬁcant from the standpoint of public health microbiology.
Holidays and Evenings in the Gymnasiums and Progymnasiums of the Tomsk Province in the Second Half of the 19th — Early of the 20th Century
Authors: Goncharov Yu.M. , Bogdanov E.D.
Published: August 2021

Modernization processes in Russia in the second half of the 19th — early of the 20th centuries led to significant changes in the education system. This was also evident in the daily life of secondary educational institutions: gymnasiums and progymnasiums. Holidays and evenings were an important part of the daily life of high schools during this period. The program of holidays, as a rule, they included a solemn part, often prayers, performances, reading poems, singing, performing musical works and distributing awards for academic success. Usually the holidays and evenings ended in an informal part, consisting of a treat, sometimes there could be dancing. Evenings in educational institutions were organized for the purpose of communication and entertainment and were less formal in nature. When arranging evenings and holidays, there could be certain difficulties. For financial help, they had to turn to benefactors, in the role of which merchants most often acted. Events could be organized jointly by different educational institutions, including gymnasiums and real schools. Holidays and evenings organized in educational institutions of secondary education (gymnasiums and progymnasiums) performed educational and socializing functions. The expanding practice of their implementation was a consequence of the modernization processes in the field of education of the Russian Empire in the second half of the 19th — early of the 20th centuries.
The Problem of Regional Identity as a Factor in the Socio-Political Crisis in Ukraine in 2004
Authors: Naumov A.O. , Naumova A.Y.
Published: August 2021

The article is devoted to the role of regional identity in the development of the socio-political crisis in Ukraine in autumn and winter of 2004, known in scientific literature as the “Orange revolution”. The authors analyze the controversial historical past of the territories that were united by the country that gained independence in 1991, and its influence on the development of processes in the field of national-state construction of modern Ukraine. The article considers the attempts of the Ukrainian authorities to develop a single national idea based on the concepts of “ukrainianness”, “sobornost” and unitarity. The leading role in this process was played by the most extreme western regions, which had their own, sometimes radically different from other regions of the country, interpretation of issues of historical memory. In practical terms, this meant the implementation of a policy of Ukrainization, especially in the field of education, which caused discontent among residents of Russian-speaking regions. The authors conclude that the unresolved problem of regional identity during the years of independence played an important role during the “Orange revolution”, which ended with an unconstitutional regime change in this Eastern European country.

O objetivo assumido nesta investigação foi o de colocar em evidência quais tecnologias/técnicas estão em jogo na experimentação de liberdades. Neste recorte, a escrita de si é enfatizada como tecnologia de si. Com base na materialidade discursiva presente nos escritos jornalísticos de Rodrigo Barchi, buscou-se cartografar uma educação ambiental menor, caracterizada pela proximidade com a micropolítica e a microfísica. Tal potência minoritária se constitui por narrativas não assimilacionistas que escapam de ecologias policialescas e normativas incitadas pela ecogovernamentalidade.

Published: August 2021

É possível encontrar ao longo das rodovias federais não conformidades ambientais que se caracterizam como débitos para com a sociedade e ambiente, podendo esses ser chamados de passivos ambientais. Tais passivos, quando de natureza física e/ou material, necessitam de obras da engenharia para mitigação. Devido ao fato desses proporcionarem um perigo instalado ou eminente, principalmente aos usuários da rodovia, à população lindeira e ao meio ambiente, e devido à quantidade de passivos existentes nas rodovias, justifica-se realizar um plano de gestão. Assim, o presente trabalho propõe um modelo de gestão de passivos ambientais rodoviários, através de um método de classificação e um método de priorização. Os métodos são consolidados em um banco de dados de 187 passivos coletados em trechos não concessionados da BR 116, bem como é realizada aplicação detalhada em um estudo de caso. O estudo se destaca por abordar de forma unificada todos os fatores que se julgaram pertinentes em uma priorização de passivos ambientais rodoviários, bem como por realizar uma análise crítica dos resultados. Desse modo, é possível estabelecer um modelo conciso de gestão das não conformidades existentes na malha rodoviária nacional, e, assim, diminuir o risco de acidentes e auxiliar na administração de recursos públicos.
The initialization of initial generating equipment maintenance schedules while a heuristic method is used
Authors: Gubin Pavel Yu. , Oboskalov Vladislav P.
Published: August 2021

Currently, heuristic methods based on iterative changing of feasible solutions set provide a perspective tool for generation equipment maintenance scheduling in power systems. Wherein effectiveness of a heuristic method depends significantly on the initial set of possible schedules or in other words quality of the method initialization. In this case, a widely used methodology of building the initial array of solutions on the basis of pseudorandom uniform generation of control variables seems to be only palliative way to access the problem.
This paper proposes alternative initialization procedure drawing on the example of generating units maintenance planning with heuristic differential evolution method. The principle of this method is to get initial set of solutions utilizing normal probability distribution to generate pseudorandom deviations from the suboptimal maintenance schedule which is to be preliminarily formed using directed search method. Following this approach allows to improve probabilistic characteristics of resultant maintenance schedule in particular to decrease median value of an objective function and its coefficient of variation, and to maximize probability to get the combination of units outage moments completely suiting operational constraints.

Authors: Il’ina Natalya A.
Published: August 2021

The task of organization a closed time-optimal control system of linear object with distributed parameters of parabolic type is considered. The object has two lumped internal controls for the power of heat sources excited in the electromagnetic field of an inductor. The proposed method for the synthesis of optimal controllers uses an alternance method for calculating the optimal program controls for each of the control actions. An example of the construction of a quasi-optimal time control system for the process of periodic induction heating of a metal workpiece with constant values of the feedback coefficients calculated for the most characteristic initial spatial distribution is given.

Teachers as market influencers: Towards a policy framework for teacher brand ambassador programs in K-12 schools
Authors: Saldaña Christopher Michael , Welner Kevin , Malcolm Susan , Tisch Eleanore
Published: August 2021

Marketing in schools has a new twist, and teachers are at the center. Corporate firms, particularly those producing education-technology products, have contracted with teachers to become so-called brand ambassadors and micro-influencers. Scant research, however, has examined these brand ambassador arrangements, leaving policymakers uninformed about the implications for students, teachers, and schools. In this article, we delve into what it means to be a teacher brand ambassador (TBA) and micro-influencer by examining the context in which these programs arose and studying current examples of TBA and TBA-like programs offered by Google, Amazon, Apple, and Microsoft. We review how these recent instantiations of marketing compare to similar practices used to sell prescription drugs to and through doctors, and we explore ethical, legal and policy issues associated with the recruitment and contracting of teachers as brand ambassadors. Further, anticipating the need for the protection of students’ and teachers’ interests as TBA programs grow as a presence in public schools, we offer a model policy framework to regulate the use of these marketing practices in schools.

Two Enfants Terribles in Dutch Exile: The Exilic Posture of Jaroslav Hutka and Ivan Landsmann
Authors: Sedláčková Lucie
Published: August 2021

This article addresses the topic of authorial posture (as defined by Jérôme Meizoz), in particular the exilic posture. Some exiled authors, listed as examples, or prototypes of that posture, were able to achieve a stable place in the Dutch literary or cultural field. This text shows, however, that some exiled authors or artists were not endowed with the crucial qualities and abilities, and it investigates what kind of qualities and abilities they missed. The Czechs Jaroslav Hutka and Ivan Landsmann spent a part of their lives in exile in the Netherlands, where they also created literary texts. The songwriter, poet and prosaist Hutka and the novelist Landsmann did acquire a firm position in the Czech cultural and literary field without really penetrating the Dutch one. This article examines the extent to which they represented the exilic posture, describes it in more detail, and provides more fitting designations. By doing so, it answers the question why these two authors did not or could not acquire an established position in the Dutch cultural field during their exile period
Two Art Exhibitions as Dialogic Events in the History of Czech-Norwegian Cultural Relations
Authors: Juříčková Miluše
Published: August 2021

The article analyses two art exhibitions in the context of Czech-Norwegian relations, presenting both the Czechoslovak book exhibition in Oslo (1937) and the Norwegian painting and applied art exhibition in Prague (1938) as important parts in a bilateral cultural dialogue. The promising initial communication in form of a mutual information exchange was soon disrupted by the beginning of World War II and post-war politics.

Investigation of acid hydrolysis for carbohydrate analysis in kraft black liquor
Authors: Maitz Silvia , Kienberger Marlene
Published: August 2021

Black liquor (BL) from the kraft process is considered a promising feedstock for several biorefinery scenarios. Besides lignin and carboxylic acids, this liquor also contains hemicelluloses and their degradation products. A simple and reliable detection of those is of importance for further processing of the liquor. The present paper presents a thorough investigation of quantitative analysis of carbohydrates, by performing acid hydrolysis experiments with a concentrated BL sample of 44% total dry solids. The hydrolysates were then analysed for the four monosaccharides arabinose, xylose, galactose and glucose, by high performance ion chromatography (HPIC) with pulsed amperometric detection. The amount of sulphuric acid needed for complete hydrolysis of the carbohydrates was determined in the range of 3.5–5 mol kg−1 of BL. A lower acid concentration led to insufficient liberation of galactose and glucose, while higher acid concentrations led to degradation of arabinose and xylose. The carbohydrate degradation was also investigated over time for different dilutions and hydrolysis temperatures. These experiments confirmed that the hexoses require considerably harsher conditions for complete liberation compared to xylose and arabinose. The use of internal recovery standards (RSs) was tested; the highest recoveries were obtained by direct spiking of the samples with the RS prior to hydrolysis.

In Lab-On-Chip (LOC) applications, micromixing is the most important step to obtain fast analytical response in many biochemical and biological detections. Design and realization of smaller and shorter mixers with higher efficiency has become a necessity more than a recommendation. In this work, a numerical optimization of a passive mixer with a serpentine-shaped channel is proposed. By considering a laminar flow regime, the continuity and momentum equations, along with the advection-diffusion equation, are solved to evaluate the mixing performance. The optimization of the slanted grooves micromixer with a serpentine channel is achieved using computational fluid dynamics (CFD) and response surface methodology (RSM) based on Box-Behnken design. This method is used to find a second-order polynomial regression model and to obtain the optimal groove design. The considered objective function is the mixing index, while the four design variables are: the number of grooves per half cycle (N), the groove angle (θ), the groove depth to channel height ratio (d/h) and the ratio of groove width to channel width (Wd/W). The optimization results indicate that the highest values of each selected interval of the groove depth to channel height ratio (d/h) and the angle between the radius and the groove (θ), on the other hand, the ratio of groove width to channel width (Wd/W) of about 0.45 are desirable to promote faster mixing. The Flow behaviour in optimized “slanted grooves mixer (SGM) with serpentine channel was tested for low Reynolds number Re ranging between 0.3 and 5, and the results have shown that in the range of Re from 0.3 to 0.7 the mixing index is greater than 85%, for large range of Re from 1 to 4.5, the mixing index reaches the value of 93% in the first cycle of the channel and it approaches 100% for channel length of 1.25 mm from the inlet of the channel. Thus the most important result of this work shows that higher efficiency is obtained for short distance and the required pressure drops decreases. This micromixer can be selected as a good candidate in applications that require a high degree of mixing with relatively small length mixing as polymerase chain reaction (PCR) in the analysis and extraction of DNA.
Acquisition of attributive adjectives and noun adjuncts by L3 learners of French and German: further evidence for the typological primacy model (TPM)
Authors: Jamali Maryam , Jabbari Ali Akbar , Razmi Mohammad Hasan
Published: August 2021

This investigation explored the impact of prior acquired languages in the acquisition of third language (L3) at initial stages. The required data were gathered via two groups of L3 learners: 27 learners of L3 French and 26 learners of L3 German during a grammaticality judgement task (GJT) and an element rearrangement task (ERT) to test the placement of noun adjuncts and attributive adjectives. Both groups had acquired Persian as the first language and English as the second language. The participants were assigned to two L2 proficiency level groups (intermediate and advanced). The findings revealed that L3 German participants outperformed L3 French learners in the attributive adjective placement in both tasks as well as the noun adjunct in the GJT task. The L3 groups showed similar levels of performance in the ERT noun adjunct task. Additionally, the effect of L2 level of proficiency was not significant. The results also indicated that the typological similarity of L2 English to German rather than French rendered a facilitative effect on task performance in the L3 German group and a non-facilitative effect in the L3 French group. This study provides evidence for the Typological Primacy Model (TPM) of L3 acquisition suggesting that L3 learners are influenced by the typological similarities of the previous languages they have already acquired.

Authors: Ng Jeremy Y. , Anagal Mrinal , Bhowmik Trisha
Published: August 2021

Objectives

The purpose of this systematic review of qualitative studies is to explore patients’ perceived effectiveness of utilizing complementary and alternative medicine (CAM) for the treatment and/or management of low back pain (LBP).

Methods

MEDLINE, EMBASE, AMED, and CINAHL were systematically searched from database inception until May 2020. Eligible articles included qualitative data about LBP patients’ perceptions of using CAM.

Results

Of 1,567 items, 1,542 items were excluded; the remaining 25 articles were included in this review. Three themes emerged as follows: physical benefits; mental health benefits; and negative or no perceived effectiveness of CAM on patients with LBP.

Conclusions

This study explores perceptions of CAM effectiveness among patients with LBP. These findings provide valuable information to CAM and non-CAM practitioners regarding the importance of individualized patient care based on their preferences, values, needs, and perspectives. Further exploration could include practitioners’ perceptions of CAM and their impact on the patient-practitioner relationship.
Some Thoughts Evoked by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021
Authors: Froehlich Thomas
Published: August 2021

The paper offers some thoughts prompted by the research paper published by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-Thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021. It highlights two significant contributions, an analysis of the misinformation in the COVID-19 pandemic and the notion of alethic rights, the right of truth of patrons based on the work of D’Agostini. This reflection then situates the COVID-19 misinformation campaign within the broader disinformation ecology within which it exists. While it agrees that alethic rights are an important ethical framework, it wonders whether it practically advances work beyond that libraries and librarians are already doing, e.g., in collection decisions, approaches to reference questions, or library programming. It looks at the debate between John Swan and Noel Peattie on the inclusion of books representing outright lies in the collection (e.g., Holocaust denial). It then contrasts a right to information and authorities propagating and validating that information with a right to misinformation and authorities for propagating and validating that misinformation that exists within disinformation ecologies. The problem of truth, its authorities and its context appears to be more complicated than an appeal to alethic truths: for example, liberals and conservatives differ on the meaning of a rational consensus on contentious political matters, such as climate change. Given the dire consequences of misinformation on democracies and public health, an appeal to professional neutrality is woefully inadequate. There must be proactive resistance, if not outright repudiation.

Influences of poling temperature and elongation ratio on PVDF-HFP piezoelectric films
Authors: Jin Zhaonan , Lei Dan , Wang Yang , Wu Liangke , Hu Ning
Published: August 2021

Poly(vinylidene fluoride) (PVDF) and its copolymers exhibit excellent piezoelectric properties and are potential materials for high efficiency energy harvesting devices. In this study, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) films are prepared by the solution casting method. The prepared film is then subjected to mechanical stretching and poling process. By adjusting the temperature of the poling process and the elongation ratio of the mechanical stretching process, the relative content of β-phase F(β) increases significantly, leading to high piezoelectric performance. The maximum output voltage of the PVDF-HFP films poled at 40°C reaches 3.67 V, 71% higher than that of the films poled at room temperature. Fourier transform infrared spectroscopy analysis (FTIR), XRD (X-ray diffraction), and differential scanning calorimetry are used to investigate the influences of mechanical stretching and poling process on the crystal structure to discover the enhancement mechanism. This work provides a straightforward and low-cost route to prepare high piezoelectric PVDF-HFP-based materials.
Exploring the Craft of Exilic Thinking/Becoming
Authors: des Bouvrie Nicole
Published: August 2021

Being-at-home in a particular, determined, world is dangerous for thinking. For thinking to be thinking/becoming, one should not get too comfortable. For thinking is to not arrive back home, in the same place one begins. But how to escape the world that has created who you are, gave you purpose and a past? How to make sure the future is not a repetition of the Same? How to break away from something that you need? In this article, my aim is not to give one more solution to this fundamental problem that is in essence an ethical problem. For providing a refuge, a new theory, a new methodology, would be providing a new island for those who realise that a flood is endangering their own island. My aim is to exercise the craft of exilic thinking as a way to deal with the contradiction already pointed out by Heraclitus and Parmenides – “We both step and do not step in the same rivers. We are and are not.” Exilic thinking as a craft of fragilising the self establishes a matrixial borderspace through which the impossible becomes possible.
Competition and Schedule Padding in the US Airline Industry
Authors: Yimga Jules
Published: August 2021

Disclosure programs can help consumers with limited information about product quality make better purchase decisions. A quality disclosure mandate such as the On-Time Disclosure Rule in the U.S. that requires airlines to provide information on the quality of their products can be beneficial, but can also be counterproductive if it encourages airlines to act deceptively by “gaming” the system. If airlines care about public perceptions of their on-time record, they have an incentive to improve their on-time performance ranking by resorting to unscrupulous means such as padding their schedules beyond normal time required to absorb scheduling stochastic fluctuations. This study investigates the impact of competition on airline schedule padding. We construct a measure for schedule padding under different optimal flight time choices. Using different measures of market structure, we find that more competitive (concentrated) markets are subject to less (more) schedule padding.
