Dielectric ceramic materials are well-recognized in the semiconductor industry because of their exceptional thermal stability, chemical resistance, and crystallinity. Despite their potential applications, these are also demanded in wireless communication. This paper reports the structural, morphological, and dielectric properties of sol-gel-derived CaZnAl2O4 ceramic nanoparticles. X-ray diffraction (XRD) analysis exhibited the polycrystalline characteristic of the CaZnAl2O4 nanoparticles with their crystallite size of 13 nm. Fourier-Transform infrared spectroscopy (FTIR) analysis confirmed the relevant vibration peaks of various functional groups present in the ceramic nanoparticles. Surface morphology study demonstrated the preparation of spherical grains with their mean diameter of 16 nm. The concentric rings also confirm the crystallinity of the nanoparticles that appeared in the selected area diffraction pattern. Furthermore, dielectric properties investigation showed the variation of dielectric permittivity from 23.76 to 21.67 as a function of increased frequency. Similarly, the dielectric loss is found to decrease from 0.047 to 0.039. As a result, the conductivity increased from 1.324 μS/m to 3.639 μS/m as a function of applied frequency.

An anodizing method was used to produce TiO2 nanotubes (TNTs) on Ti metal bases. These tubes were transformed into lobed nanotubes (LNTs) by heating at 6000C as scanning electron microscopy (SEM) images showed. A rapid break down anodizing (RBA) technique was utilized to produce TiO2 nanoparticles (TNPs). These particles were deposited on LNTs by the electrophoretic deposition (EPD) method. An X-ray diffraction (XRD) test revealed the polycrystalline composition of the formed LNTs and the amorphous structure of TNPs. The bioactivity of LNTs and the deposited TNPs on the LNTs were tested by immersing them in simulated body fluid (SBF) for one month. For the two samples, XRD patterns showed the appearance of small peaks of hydroxyapatite (HAp), which indicates the bioactivity of these samples. SEM images show that the HAp layer on LNTs was in the form of protrusions, while on TNPs it was in the form of crossed filaments.

Published: April 2022

Carbon dioxide-induced stress corrosion cracking (CO2-SCC) is an environmentally assisted corrosion cracking phenomenon that has recently been identified as a new failure mode in flexible pipe armor wires. The phenomenon has been observed to take place notably in severe CO2 environments and is a cause of great concern to the flexible pipe industry. As its detection, a diverse and extensive testing program has been established to develop an understanding of the phenomenon and define safe application limits for carbon steel wires to prevent the initiation of CO2-SCC. Several different testing methodologies have been explored and small-scale laboratory testing has played an instrumental role in this overall effort. This paper focuses on the results from three different small-scale testing methodologies and the impact of different parameters such as CO2 fugacity, temperature, and confinement that play a crucial role in the initiation of CO2-SCC. Furthermore, careful prominence has been given to the test setup and methodology that has been rigorously developed over the last few years. With this developed protocol in place, CO2-SCC has been effectively reproduced on all wire grades in a small-scale testing environment. Results have also shown that for a CO2 fugacity greater than 15 bar and applied stress at 100% of the actual yield strength, all existing wire grades are susceptible to CO2-SCC thus creating significant limitations to flexible pipe design with respect to this new failure phenomenon.

Introduction

Diabetic cardiomyopathy (DCM) is a serious complication that frequently occurs in patients with type 1 diabetes (T1D) necessitating early diagnosis. The aim of the current study was to detect subclinical DCM in Egyptian children and adolescents with T1D and evaluate the effect of antioxidants on myocardial dysfunction.

Material and methods

The current prospective observational cohort study included 81 T1D patients (9-20 years old) with diabetes duration > 4 years compared to 50 age and sex matched non-diabetic controls. Serum N-terminal prohormone of brain natriuretic peptide (NT-proBNP) was assessed in addition to conventional echocardiography, tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE). Patients with myocardial dysfunction were supplemented with vitamin E (α-tocopherol) as an antioxidant for 1 year, then follow up echocardiography was done.

Results

NT-proBNP was elevated in 73 (90.1%) patients, 50.6% had left ventricular (LV) diastolic dysfunction, 14.8% had right ventricular (RV) diastolic dysfunction, 84% had LV systolic dysfunction and 91.4% had RV systolic dysfunction with statistically significant difference compared to controls. There was a significant negative correlation between LV global longitudinal strain (GLS) and NT-proBNP (p<0.001, r=-0.796). ROC curve analysis showed that NT-proBNP at a cut-off point ≥ 195 ng/ml detected LV systolic dysfunction function with 89.7% sensitivity and 84.6% specificity. Follow up after one year of α-tocopherol supplementation revealed significant improvement in LV systolic and diastolic functions as well as RV systolic dysfunction.

Conclusions

NT-proBNP and non-conventional echocardiography were useful in early detection of subclinical cardiomyopathy in patients with T1D. Antioxidant treatment improved subclinical myocardial dysfunction in T1D patients.
Who’s Chinese?
Authors: Ang Sylvia
Published: April 2022

This chapter explores how Singapore acts as an important lens to study the
anxieties toward China’s ascent. As a postcolonial hybrid society which
has a majority-ethnic-Chinese population, Singapore is both an insider
and outsider in its relationship to China. It provides an overview of the
Singaporean context and its relationship with China and Chinese identity.
It discusses the institutional and social context of Singapore and analyses
how the state has constructed an imaginary of Chineseness to homogenise
the Singaporean-Chinese population. The arrival of new Chinese migrants
in recent years has forced Singaporean-Chinese to question the state’s
imaginary of Chinese identity and Chinese homogeneity. This chapter
critically explores the assumption that blood and descent predetermine
shared cultural consciousness.
In the new Chinatown
Authors: Ang Sylvia
Published: April 2022

This chapter analyses how Chinatowns and their link to Chinese identity
is imagined. Through a textured description of both the new and old
Chinatowns, it explores Singaporean-Chinese imaginaries of a “new”
Chinatown and how it is linked to racialization discourses. It shows that
the racialization discourse is subtle and reinforced by the media as well
as state structures inherited from the nation’s colonial past. Chinese
migrants’ response of self-orientalisation adds to the complex rubric of
racialization. This chapter offers a broader reflection of how racialization
of migrants can be produced by the intersection of Chinese and global
capital with local modernities.
Introduction: Contesting Chineseness
Authors: Ang Sylvia
Published: April 2022

This chapter introduces the paradox of politics among ethnic Chinese.
It provides a detailed exploration of global anxieties to China’s ascent
and the outflow of Chinese immigrants. The case study of Singapore is
introduced as a mirror of the anxieties faced by cities with new flows
of Chinese immigration. Both Singaporean-Chinese and new Chinese
migrants’ stories are detailed to draw the audience into the cultural
politics of being Chinese. The chapter explains the book’s framework
through critically engaging scholarship across various fields including
migration and ethnic studies. A methodology section justifies the book’s
focus on Chinese subjects’ everyday lives which are shaped, though not
necessarily determined, by global and state discourses. An overview of
the chapters follows.
Vaguely Specific: Resonant Historicity with Chesóls
Authors: Abels Birgit
Published: April 2022

This chapter explores the conceptual ramifications of meaningfulness as
an analytical concept for musical performance. Expounding the concept’s
scope, the chapter introduces the neo-phenomenology of atmospheres
(Schmitz, Böhme) more systematically and proposes ways of thinking
through music with atmospheres. Based on an in-depth analysis
of chesóls, a Palauan solo chant, I flesh out the layered complexity of
musical meaningfulness: it often presents itself as an atmosphere that
will be experienced with the felt body, leveraging both affective and
interpretative frames but exceeding both by way of its primarily corporeal
experiential quality. This finding opens vistas to overcoming several of
the binaries lingering in more dominant scholarly traditions of thinking
through affective publics.
Listening with the Dancing Body: Ruk and Movement’s Incipiency
Authors: Abels Birgit
Published: April 2022

This chapter inquires into the bodily dimensions of the interlacing
of world with self, into the role of bodily experience in negotiating
historical and cultural configurations, and further into the imbrication
of bodily practices and complex social systems. I show how the
ruk (Palauan men’s dance) is a cultural practice enacting the already
motion-laden body. Beyond the flesh, it actualises the human body
in movement, allowing it to continually transform in sound while
recomposing along historical, social and cultural configurations. When
musical movement acts on bodily movement in this way, it creates
resonances that travel back and forth between emotion, discourse
and memory as they correlate with Palauan temporo-spatiality via
felt-bodily attunement to traditional chant repertoire. These resonances
are intrinsically atmospheric.
“Rak, Where Is He Now?” Presence | Present
Authors: Abels Birgit
Published: April 2022

This chapter explores how meaningfulness and meaning relate in music,
and how, structurally and texturally, music may ‘have meaning’ and
yet mean far more beyond this meaning. Presenting an exploration of
omengeredákl, a type of women’s group chant, and exploring Palauan
notions of temporality, I single out “effects of meaning” and “effects of
presence” (Gumbrecht 2003), showing how the dynamics arising between
them lead to the emergence of a distinctly sonic atmosphere. There is no
such thing as binary oppositions in atmospheres.
Of Magic and Meaningfulness : Chelitákl Rechuódel and the Feltbodily Dimensions of Spiritual Practice
Authors: Abels Birgit
Published: April 2022

This chapter explores musical ólai (magic) practices. The practice of magic
in traditional Palau required for spells not only to be recited but to resound
as chelitákl rechuódel, traditional chant repertoire. The reason for that
is that the magic could be implemented only through the repertoire’s
capacity to link, via the felt body, the present moment experientially with
Palauan ‘deep time’. This shows to what extent the meaningfulness of
chelitákl rechuódel resides in music’s capacity to connect the categories
of time, space and sociality into a whole; that whole will then emerge as
a deep sense of Palauanness. Chelitákl rechuódel make Palauanness felt
in an encompassing sense. This is how “music worlds”.

Effect of the implementation of the Progression Education Policy at public institutions : a case study of Pinetown district in KwaZulu-Natal, South Africa
Authors:   , Makhanya Philasande Dedictus
Published: April 2022

The purpose of the study is to investigate the effect of the implementation of the progression of education policy at public institutions. It sought to explore the factors that qualify a student for advancement, examine the behaviour and academic performance of progressed students in a classroom and seek ways of resolving the unintended consequences the policy has caused within the schooling system. A qualitative interpretive paradigm was adopted. Data was collected using semi structured interview questionnaires administered to teachers and learners from conveniently selected four schools in the Pinetown District Department of Education from a sample of 80 participants. The outcomes of this systematic inquiry have revealed massive and complex effects of the implementation of the progression of education policy. Concerning learners, these include the inability to cope with the next level, future poor performance and capabilities, lack of interest in learning, students’ reliance and entitlement. Regarding teachers, these include teacher frustration, delusion and false confidence, poor performance in Grade 12, and lack of key attributes amongst many others. As recommendations to the implementation challenges of the PPP and future educational policy matter, bottom-up consultation, monitoring and evaluation, and alternative ways of pedagogy were seen as integral strategies to remedy the implementation thereof. Whilst a plethora of interventions and recommendations were made, immediate interventions include extra classes, practical and technical skills, experimental work, repetitive teaching, knowledge and understanding, reducing over-crowded classes, identification of learner difficulties at an early stage, and parental involvement featured prominently
The role of Green Campus Initiative (GCI) as integral part of environmental and sustainable resources utilization : a case study of Durban University of Technology
Authors:   , Shange Hlanganani Siduduzo
Published: April 2022

The Green Campus Initiative (GCI) is quite an old movement around the world, but it was only initiated in South Africa in 2012 by the Minister of Higher Education and Training, Dr Blade Nzimande. The reason behind the initiating this movement was to make institutions of higher learning mindful of the negative natural effects that are brought about by their everyday socio-economic activities. Moreover, the GCI movement looked to provide a platform for students to gain information and get involved in the movement for change and sustainability. Numerous universities in South Africa participate in GCI, but encounter numerous challenges and limitations, which curtail full-scale implementation and beneficiation. The objectives of this study were to assess the progress on the Green Campus Initiative programs, examine the impact that the GCI has had at DUT, determine the challenges of implementing GCI at the DUT and investigate mechanisms of promoting GCI at DUT. Extensive literature review was conducted to locate the study within existing research. This study used qualitative research method, conducting interviews with some stakeholders and questionnaires to others. Data were analysed using qualitative techniques such as themes, words, word cloud, word trees and others. The study found that while quite a number of activities had been done in the past to promote GCI and prizes won at interuniversity competitions, GCI at DUT was still facing a number of challenges. These challenges emanated mainly from the lack of environmental policy, which would enable the university to develop a fully-fledged GCI office. The study also discovered that academic departments were involved on an ad hoc voluntary basis resulting in some not promoting GCI.
A comparison of symptoms derived from a C4 trituration and the materia medica of an existing, well-proven homoeopathic remedy
Authors:   , Goote Chryso
Published: April 2022

C4 trituration provings are a somewhat controversial method of uncovering the therapeutic value of homoeopathic remedies. The key advantage of this method over traditional proving methods is that a substance can be proved in a matter of hours, rather than weeks or months. However there is a lack of research to show whether the results of the two methods are comparable. AIM The aim of this study is to establish whether symptoms elicited in a C4 trituration proving are comparable to symptoms produced in traditional provings of the same substance. If a similarity can be demonstrated – even on a single substance – it may encourage further studies to determine the extent to which C4 provings can be used in association with, or instead of, traditional provings as a means of developing homoeopathic remedies. METHOD Ten triturators were recruited from an existing group of experienced triturators to prove an unknown substance. Data were harvested from debriefing sessions and from notes kept by triturators during the sessions, and these were transcribed and converted to rubrics. An unprejudiced repertorisation was undertaken in an (unsuccessful) attempt to identify the substance before unblinding. After the substance was revealed to be Borax, the rubrics from the C4 proving were statistically compared to rubrics associated with Borax in Radar 9.0, the electronic version of the repertory Synthesis: Repertorium Homoeopathicum Syntheticum (2004), which reflects traditional provings of this substance. The statistical comparison of rubrics was performed in SPSS; a Pearson Chi-Square test was applied to establish statistical significance; and a Cramer's V test was used to determine the strength of that association. RESULT The comparison failed to find a significant correlation between the rubrics from the C4 proving of Borax and traditional provings of the same substance. At a chapter level, there were significant associations between symptoms relating to Hearing and Kidneys but, for reasons discussed at length in the report, these results must be treated with circumspection. CONCLUSION While C4 provings are faster than the traditional method, as refined by Sherr, in view of the above findings it cannot be recommended that C4 provings be considered as a means of developing homoeopathic remedies instead of traditional provings, because C4 provings would not produce a complete symptom picture. RECOMMENDATIONS Recommendations arising from the study include that the exercise should be repeated with a different substance and group of provers, preferably with confidential debriefing of participants (as opposed to group debriefing, which is the norm for C4 provings), to verify these findings.

Seguridad con IP seguro en internet (IPSEC)
Authors: Aparicio-Izurieta Viviana Vanessa
Published: April 2022

Antes de IPSec, las soluciones disponibles en el mercado para lograr una transmisión segura de datos a través de Internet sobre IP dependían de la aplicación del fabricante; En otras palabras, son decisiones aisladas. Aunque generalmente funcionan bien, tienen el problema de que los protocolos estables de diferentes fabricantes no son compatibles entre sí o son difíciles de conciliar; Si la organización y todos los actores con los que interactúa están utilizando la misma solución tecnológica, no debería haber ningún problema. Sin embargo, el punto común es que existe algún tipo de heterogeneidad relacionada con los dispositivos de comunicación, sistemas operativos, facilidades de transmisión de datos, etc., lo que significa que utilizar una solución de estabilización propietaria no es muy conveniente.IPSec, publicado en 1994 en RFC 1636, ha superado ingeniosamente esta incompatibilidad, ya que se basa en estándares, lo que supone una ventaja a su favor. Su diseño es completamente independiente del sistema operativo, plataforma informática y tecnologías subyacentes utilizadas, por lo que la interoperabilidad está garantizada. Además, está lo suficientemente abierto para incorporar los desarrollos tecnológicos y criptográficos necesarios en el futuro. Tanto es así que está incluido en el marco íntegramente en IPv6.
Towards improved analysis of short mesoscale sea level signals from satellite altimetry
Authors: Quilfen Yves , Piolle Jean-François , Chapron Bertrand
Published: April 2022

Abstract. Satellite altimeters routinely supply sea surface height (SSH)
measurements, which are key observations for monitoring ocean dynamics.
However, below a wavelength of about 70 km, along-track altimeter
measurements are often characterized by a dramatic drop in signal-to-noise
ratio (SNR), making it very challenging to fully exploit the available altimeter
observations to precisely analyze small mesoscale variations in
SSH. Although various approaches have been proposed and applied to identify
and filter noise from measurements, no distinct methodology has emerged for
systematic application in operational products. To best address this
unresolved issue, the Copernicus Marine Environment Monitoring Service
(CMEMS) actually provides simple band-pass filtered data to mitigate noise
contamination of along-track SSH signals. More innovative and suitable noise
filtering methods are thus left to users seeking to unveil small-scale
altimeter signals. As demonstrated here, a fully data-driven approach is
developed and applied successfully to provide robust estimates of noise-free
sea level anomaly (SLA) signals (Quilfen, 2021). The method combines empirical mode
decomposition (EMD), used to help analyze non-stationary and non-linear
processes, and an adaptive noise filtering technique inspired by discrete
wavelet transform (DWT) decompositions. It is found to best resolve the
distribution of SLA variability in the 30–120 km mesoscale wavelength band.
A practical uncertainty variable is attached to the denoised SLA estimates
that accounts for errors related to the local SNR but
also for uncertainties in the denoising process, which assumes that the SLA
variability results in part from a stochastic process. For the available
period, measurements from the Jason-3, Sentinel-3, and SARAL/AltiKa missions
are processed and analyzed, and their energy spectral and seasonal
distributions are characterized in the small mesoscale domain. In anticipation
of the upcoming SWOT (Surface Water and Ocean Topography) mission data, the
SASSA (Satellite Altimeter Short-scale Signals Analysis, https://doi.org/10.12770/1126742b-a5da-4fe2-b687-e64d585e138c, Quilfen
and Piolle, 2021) data set of denoised SLA measurements for three reference altimeter
missions has already been shown to yield valuable opportunities to evaluate global small
mesoscale kinetic energy distributions.
Comparing the transport-limited and ξ–q models for sediment transport
Authors: Braun Jean
Published: April 2022

Abstract. Here I present a comparison between two of the most widely used reduced-complexity models for the representation of sediment transport and deposition processes, namely the transport-limited (or TL) model and the under-capacity (or ξ–q) model more recently developed by Davy and Lague (2009). Using both models, I investigate the behavior of a sedimentary continental system of length L fed by a fixed sedimentary flux from a catchment of size A0 in a nearby active orogen through which sediments transit to a fixed base level representing a large river, a lake or an ocean. This comparison shows that the two models share the same steady-state solution, for which I derive a simple 1D analytical expression that reproduces the major features of such sedimentary systems: a steep fan that connects to a shallower alluvial plain. The resulting fan geometry obeys basic observational constraints on fan size and slope with respect to the upstream drainage area, A0. The solution is strongly dependent on the size of the system, L, in comparison to a distance L0, which is determined by the size of A0, and gives rise to two fundamentally different types of sedimentary systems: a constrained system where LL0. I derive simple expressions that show the dependence of the system response time on the system characteristics, such as its length, the size of the upstream catchment area, the amplitude of the incoming sedimentary flux and the respective rate parameters (diffusivity or erodibility) for each of the two models. I show that the ξ–q model predicts longer response times. I demonstrate that although the manner in which signals propagates through the sedimentary system differs greatly between the two models, they both predict that perturbations that last longer than the response time of the system can be recorded in the stratigraphy of the sedimentary system and in particular of the fan. Interestingly, the ξ–q model predicts that all perturbations in the incoming sedimentary flux will be transmitted through the system, whereas the TL model predicts that rapid perturbations cannot. I finally discuss why and under which conditions these differences are important and propose observational ways to determine which of the two models is most appropriate to represent natural systems.

Published: April 2022

Background: Heat strokes are predictable and preventable, so sufficient public awareness of the condition and preventative practices are essential in hot and humid countries such as the United Arab Emirates (UAE). This study aims to assess the level of awareness (knowledge, prevention, and management) of heat stroke among UAE residents.
Methods: Survey-based study of a random sample of adults (?18 years) in four different cities of UAE. The questionnaire included 37 questions on knowledge and practices. Correct answer was equal to one point and total scores were calculated. The average of participants’ total scores was taken as cut-off point. Multivariate logistic regression was used to identify associated factors with below-average awareness.
Results: A total of 402 people participated in the study, with age average 33±12 years and 48.5% were female. Only 1 person achieved a perfect score and 0.7%, 10%, and 17.7% achieved above average scores in knowledge, practices, and management, respectively. Seven percent of participants had never heard of a heat stroke before. A third of participants (32%) did not know that severe heat strokes can lead to death. Males are at higher risk of having a poor level of knowledge (Odds ratio [OR]=1.65; 95% confidence interval [95%CI]=1.10-2.47). The older the population the poor was the knowledge about heat stroke (OR=1.39, 95%CI=1.03-1.89).
Conclusion: The results of this study show that a huge proportion of the population in the UAE does not have sufficient knowledge about heat stroke, its prevention, and management. Governmental institutes should increase awareness of heat stroke.
Teaching introductory statistics for evidence-based practice: integration of context
Authors:   Mercy College, Hassad Rossi
Published: April 2022

The ability to critically evaluate quantitative research outcomes is an essential skill for effective decision-making, particularly in the health and behavioral sciences, where the focus is on evidence-based practice and clinical judgment. Introductory college-level statistics courses can serve as a vehicle for engendering these competencies. In this regard, the first course in statistics has been targeted for reform, aimed at building a meaningful foundation for statistical thinking. There is a consensus among educators that the goal of the introductory statistics course should be to foster statistical literacy by emphasizing concepts and applications rather than mathematical procedures and computations; an instructional method that embodies active- learning. Underpinning this pedagogical approach is the constructivist philosophy which regards context knowledge as central to meaningful and appropriate analysis, interpretation and use of data. This paper presents a model for conceptualizing an introductory statistics course to foster evidence-based practice (EBP). It depicts a unifying and holistic view of statistics, and posits that meaningful evidence results from the interaction of statistical methods with the data context, which refers to the research design, the underlying theory, and the practice domain.
Application of ICTS to teaching statistics to non statisticians

Published: April 2022

The expansion of the university system coupled with the changes introduced by the new information and communication technologies (NICT), have a direct effect on the traditional methods of education. In fact, ICTS have significantly increased the available information, altering the methodology of statistical treatment. These transformations are progressively being incorporated into the university education, which should take up the challenge of training individuals prepared to efficiently developed its activity in the field of the new information society. This work assesses the experiences in the application of new technologies to the teaching of statistics, describing the role of the software used for practical work and analyzing the possibilities of the Internet in a dual perspective: as a supplement to classroom teaching and as a support for a virtual classroom based on the foregoing of a methodological proposal that tries to adapt the use of technology to different curricular proposals belonging to private and public universities, in different educational establishments, and in situations of marked difference in the amount of students in charge of each professor.
E-learning or blended learning – enriching statistics for business students
Authors:   University of Klagenfurt, Borovcnik Manfred
Published: April 2022

There has been much interest within the scientific community to use the potential of new technol- ogies for teaching since they have become widely available. We will deal with two questions: What has emerged out of e-learning endeavours? What are vital issues for their success? The specific situation for learners within an e-learning setting will be analysed in the light of two “events”: First, the general discussion of the impact of technology on teaching at the ISI con- gress in Lisboa in 2007, and second, a series of papers on blended learning in the International Statistical Review published in the same year. Our long-term experience with a blended learning course on introductory statistics for business students will serve as background to respond to key questions for the success of e-learning. As an interactive exchange of feedback between students and staff has proved to be essential in the evaluation of our course, this paper gives support for blended learning enrichment of courses to assist the students in their learning process.
Vamos contar: a communication channel between ibge and brazilian educators
Authors:   Instituto Brasileiro de Geografia e Estatística, Miranda Tatiana
Published: April 2022

This article presents the objectives and format of Vamos Contar, a project by the Brazilian Institute of Geography and Statistics. In order to fulfill the Institute’s mission “to portray Brazil by providing the information required to the understanding of its reality and the exercise of citizenship”, it is not enough to only produce and disseminate geographic and statistical information. In a country such as Brazil, in which the population faces major difficulties in the educational field, the Institute realized it could play an active role as a contributor to people’s qualification so as to enable them to autonomously read and interpret data concerning their reality. Targeted at providing informative material and teaching resources for the pedagogical work based on data produced by the Institute, Vamos Contar was born as an educational project aimed at communication with teachers.
Enabling learners to discover real stories in official statistics with a new synthetic unit record file of the new zealand income survey 2011
Authors:   Statistics New Zealand, Keegan Alan , Tideswell Andrew ,   Statistics New Zealand
Published: April 2022

Learners of statistics need datasets reflecting real life contexts. Unit record datasets have interesting properties and contain stories that could engage learners. However, NSOs have legal and ethical duties to protect unit records. To enable access to these stories, Statistics New Zealand has published Synthetic Unit Record Files (SURFs) produced using several methods. With a new SURF based on the New Zealand Income Survey 2011 (NZIS 2011), we enable learners to access a new unit record dataset. Learners have an opportunity to discover and tell the stories about their region or country that are in the actual sample dataset. Learners can experience for themselves interesting aspects, such as: disaggregated data, semi-continuous distributions, and formal classifications. We hope learners will welcome the value of official statistics, as contributors of data and consumers of information from it.
Statistics education in new zealand, and its influence on the iase
Authors:   Victoria University of Wellington, Forbes Sharleen
Published: April 2022

For some time, New Zealand has been leading the world in terms of the focus and scope of its statistics curriculum in schools. The curriculum is characterised by its data handling, and in more recent years, data visualisation approach. In 2013 bootstrapping and randomisation will be added to the curriculum achievement objectives for the senior secondary school (Ministry of Education, 2012). This paper gives an historical perspective of the people and groups that have influenced the development of the New Zealand curriculum and outlines the influence and impact of some of these New Zealanders, such as Professors David Vere-Jones and Chris Wild together with Maxine Pfannkuch and John Harraway, on the International Association for Statistical Education (IASE). The roles of both the IASE and the local professional statisticians’ association, the New Zealand Statistical Association (NZSA), are discussed together with the possible long-term impact of new statistical literacy based school curriculum in New Zealand on tertiary statistics teaching.

Published: April 2022

Providing practical and relevant experience with the data investigative process is known to help engage students in quantitative research methods courses; however, limited student experience, time constraints, and ethical concerns present serious challenges to this goal. Recent advances in technology may provide innovative solutions. This paper reports on the development and implementation of a series of two-hour weekly computer laboratories that simulated the data investigative cycle in a research methods course for psychology students. The technologies included an online virtual human world, known as the Island, cloud collaboration technology and a statistical package. Each laboratory session aimed to engage students in all stages of the data investigative cycle, specifically: stating a problem, planning a study, gathering and analysing data and drawing conclusions. Student feedback from the sessions was overwhelming positive, which highlights the potential of combining innovative technologies to actively engage students in learning research methods and statistics.
Statistics education and human rights monitoring
Authors:   University of Education Ludwigsburg, Engel Joachim
Published: April 2022

The paper discusses the role of statistical knowledge for promoting and monitoring human rights. It is based on the assumption that skills to understand and analyze trends in quantitative data are needed to evaluate situations involving civil, political, economic, social and cultural rights. For educators, the topic of human rights and statistics involves issues of value clarification, understanding and embracing the principles of human equality and dignity as well as skills for analyzing situations in human rights terms - topics that address the mind and the heart. Moreover, it lets students experience that statistical analyses play a role in understanding the pressing social and political issues of our time.
