Applications of Matchmoving for Forensic Video Analysis of a Fatal Sprint Car Accident: Part II
Authors: Ziernicki Richard , Gordon Martin , Knapp Steve , Leiloglou Angelos G.
Published: July 2021

This paper presents the application of the photogrammetric process known as matchmoving to analyze a racetrack video and reconstruction of a fatal Sprint Car race accident. The use of high-definition 3D laser scanning technology made it possible to accurately perform the matchmoving process on racetrack video footage to determine the path, heading, speed, and acceleration of the involved Sprint Cars. In addition to the accident racetrack, another video of a Sprint Car race on a similar racetrack, taken by a drone, was also analyzed using the same matchmoving method to evaluate the speed and yaw angle of a drifting Sprint Car.
Transition Process of Landscape Through Changing Tropical Gardens from Productive Function into Recreational Purpose
Authors: TAFAHOMİ Rahman
Published: July 2021

The urban gardens are under transformation that results in the modification of function, activity, hardscape, softscape of gardens. The aim of this paper is to analyse the transitional process of the gardens from the productive function to recreational purposes in Kigali city, Rwanda. The methodology of the research was designed qualitative methods such as interview, observation, photography, sketching, mapping, and graphical analysis. The findings identified that the transition process has affected both the configuration and composition of gardens. The configuration refers to the hardscape including buildings, walls, paving, and accessibility, and composition includes the softscape such as trees, shrubs, flowers, pots, and furniture. Additionally, this transition resulted in changing functions and activities in the gardens from productive to leisure and from private to semi-private and semi-public. This transition could be addressed to the new generation of social middle classes in the city who are raising new needs, desires, and expectations from the urban area to increase social interaction through semi-public activities.
Sticking Together Six Feet Apart: Testing the Effects of Social Distancing
Authors:   Sherwood High School, Ediriweera Minoli
Published: July 2021

Social distancing - like many other precautions taken during a global pandemic, it is easier said than done. COVID-19 is spread by respiratory droplets through coughing or sneezing (Centers for Disease Control and Prevention, 2020, para. 1). These droplets can land on someone nearby, so experts recommend practicing social distancing or self-isolation techniques to prevent contracting coronavirus. These methods include staying six feet apart from other individuals and staying home from work, school, and other large gatherings.

Abstract. Long-range transport of anthropogenic air pollutants from East Asia can affect the downwind marine air quality during spring and winter. Long-range transport of continental air pollutants and their interaction with sea salt aerosols (SSA) significantly modify the radiative forcing of marine aerosols and influence ocean biogeochemical cycling. Previous studies poorly characterize variations of aerosol particles along with air mass transport from the continental edge to the remote ocean. Here, the research ship R/V Dongfanghong 2 traveled from the eastern China seas (ECS) to the northwestern Pacific Ocean (NWPO) to understand what and how air pollutants were transported from the highly polluted continental air to clean marine air in spring. A transmission electron microscope (TEM) was used to find the long-range transported anthropogenic particles and the possible Cl-depletion phenomenon of SSA in marine air. Primary and secondary anthropogenic aerosols were identified and dramatically declined from 87 % to 8 % by number from the ECS to remote NWPO. For the SSA aging, 86 % of SSA particles in the ECS were identified as fully aged, while the proportion of fully aged SSA particles in the NWPO decreased to 31 %. The result highlights that anthropogenic acidic gases in the troposphere (e.g., SO2, NOx, and volatile organic compounds) were transported longer distances compared to the anthropogenic aerosol and could exert a significant impact on marine aerosols in the NWPO. These results show that anthropogenic particles and gases from East Asia significantly perturb aerosol chemistry in marine air. The optical properties and cloud condensation nucleation of the modified SSA particles should be incorporated into the more accurately modeling of clouds in the ECS and NWPO in spring and winter.

Abstract. We present a statistical survey of large-amplitude, asymmetric plasma and magnetic field enhancements detected outside the diamagnetic cavity at comet 67P/Churyumov–Gerasimenko from December 2014 to June 2016. Based on the concurrent observations of plasma and magnetic field enhancements, we interpret them to be magnetosonic waves. The aim is to provide a general overview of these waves' properties over the mission duration. As the first mission of its kind, the ESA Rosetta mission was able to study the plasma properties of the inner coma for a prolonged time and during different stages of activity. This enables us to study the temporal evolution of these waves and their characteristics. In total, we identified ∼ 70 000 steepened waves in the magnetic field data by means of machine learning. We observe that the occurrence of these steepened waves is linked to the activity of the comet, where steepened waves are primarily observed at high outgassing rates. No clear indications of a relationship between the occurrence rate and solar wind conditions were found. The waves are found to propagate predominantly perpendicular to the background magnetic field, which indicates their compressional nature. Characteristics like amplitude, skewness, and width of the waves were extracted by fitting a skew normal distribution to the magnetic field magnitude of individual steepened waves. With increasing mass loading, the average amplitude of the waves decreases, while the skewness increases. Using a modified 1D magnetohydrodynamic (MHD) model, we investigated if the waves can be described by the combination of nonlinear and dissipative effects. By combining the model with observations of amplitude, width and skewness, we obtain an estimate of the effective plasma diffusivity in the comet–solar wind interaction region and compare it with suitable reference values as a consistency check. At 67P/Churyumov–Gerasimenko, these steepened waves are of particular importance as they dominate the innermost interaction region for intermediate to high activity.
Drought effects on leaf fall, leaf flushing and stem growth in the Amazon forest: reconciling remote sensing data and field observations

Published: July 2021

Abstract. Large amounts of carbon flow through tropical ecosystems every year, from
which a part is sequestered in biomass through tree growth. However, the
effects of ongoing warming and drying on tree growth and carbon
sequestration in tropical forest is still highly uncertain. Field
observations are sparse and limited to a few sites, while remote sensing
analysis shows diverging growth responses to past droughts that cannot be
interpreted with confidence. To reconcile data from field observations and
remote sensing, we collated in situ measurements of stem growth and leaf litterfall
from inventory plots across the Amazon region and other neotropical
ecosystems. These data were used to train two machine-learning models and to
evaluate model performance on reproducing stem growth and litterfall rates.
The models utilized multiple climatological variables and other geospatial
datasets (terrain, soil and vegetation properties) as explanatory variables.
The output consisted of monthly estimates of leaf litterfall (R2= 0.71, NRMSE = 9.4 %) and stem growth (R2= 0.54, NRMSE = 10.6 %) across the neotropics from 1982 to 2019 at a high spatial
resolution (0.1∘). Modelled time series allow us to assess the
impacts of the 2005 and 2015 droughts in the Amazon basin on regional
scales. The more severe 2015 drought was estimated to have caused widespread
declines in stem growth (−1.8σ), coinciding with enhanced leaf fall
(+1.4σ), which were only locally apparent in 2005. Regions in the
Amazon basin that flushed leaves at the onset of both droughts (+0.9σ∼+2.0σ) showed positive anomalies in
remotely sensed enhanced vegetation index, while sun-induced fluorescence
and vegetation optical depth were reduced. The previously observed
counterintuitive response of canopy green-up during drought in the Amazon
basin detected by many remote sensing analyses can therefore be a result of
enhanced leaf flushing at the onset of a drought. The long-term estimates of
leaf litterfall and stem growth point to a decline in stem growth and a
simultaneous increase in leaf litterfall in the Amazon basin since 1982.
These trends are associated with increased warming and drying of the
Amazonian climate and could point to a further decline in the Amazon carbon
sink strength.
The 1600 Huaynaputina Eruption as Possible Trigger for Persistent Cooling in the North Atlantic Region
Authors: White Sam , Moreno-Chamarro Eduardo , Zanchettin Davide , Huhtamaa Heli , Degroot Dagomar , Stoffel Markus , Corona Christophe
Published: July 2021

Abstract. Paleoclimate reconstructions identify a period of exceptional summer and winter cooling in the North Atlantic region following the eruption of the tropical volcano Huaynaputina (Peru) in 1600 CE. Numerical climate simulations indicate a possible eruption-induced mechanism for the persistent cooling in a slowdown of the North Atlantic subpolar gyre (SPG) and consequent ocean-atmosphere feedbacks. To examine the possibility of such an eruption-induced cooling mechanism, this study compares simulations with and without volcanic forcing and an SPG shift to reconstructions from annual proxies in natural archives and historical written records as well as contemporary historical observations of relevant climate and environmental conditions. These reconstructions and observations demonstrate patterns of cooling and sea ice expansion consistent with, but not necessarily indicative of, an eruption trigger for the proposed SPG slowdown mechanism. The results point to possible improvements in future model-data comparison studies utilizing historical written records. Moreover, we consider historical societal impacts and adaptations associated with the reconstructed climatic and environmental anomalies.

Abstract. A better understanding of the hydrological functioning of
irrigated crops using remote sensing observations is of prime importance in semi-arid areas where water resources are limited. Radar
observations, available at high resolution and with a high revisit time since the launch
of Sentinel-1 in 2014, have shown great potential for the monitoring of the
water content of the upper soil and of the canopy. In this paper, a complete
set of data for radar signal analysis is shared with the scientific community
for the first time to our knowledge. The data set is composed of Sentinel-1
products and in situ measurements of soil and vegetation variables collected during
three agricultural seasons over drip-irrigated winter wheat in the Haouz
plain in Morocco. The in situ data gather soil measurements (time series of
half-hourly surface soil moisture, surface roughness and agricultural
practices) and vegetation measurements collected every week/2 weeks
including aboveground fresh and dry biomasses, vegetation water content
based on destructive measurements, the cover fraction, the leaf area index, and plant
height. Radar data are the backscattering coefficient and the
interferometric coherence derived from Sentinel-1 GRDH (Ground Range
Detected High Resolution) and SLC (Single Look Complex) products,
respectively. The normalized difference vegetation index derived from
Sentinel-2 data based on Level-2A (surface reflectance and cloud mask)
atmospheric-effects-corrected products is also provided. This database,
which is the first of its kind made available open access, is described
here comprehensively in order to help the scientific community to evaluate
and to develop new or existing remote sensing algorithms for monitoring
wheat canopy under semi-arid conditions. The data set is particularly
relevant for the development of radar applications including surface soil
moisture and vegetation variable retrieval using either physically based
or empirical approaches such as machine and deep learning algorithms. The database is archived in the DataSuds repository and is freely accessible
via the following DOI: https://doi.org/10.23708/8D6WQC (Ouaadi et al., 2020a).
Comparison of source apportionment approaches and analysis of non-linearity in a real case model application
Authors: Belis Claudio A. , Pirovano Guido , Villani Maria Gabriella , Calori Giuseppe , Pepe Nicola , Putaud Jean Philippe
Published: July 2021

Abstract. The response of particulate matter (PM) concentrations to emission reductions was analysed by assessing the results obtained with two different source apportionment approaches. The brute force (BF) method source impacts, computed at various emission reduction levels using two chemical transport models (CAMx and FARM), were compared with the contributions obtained with the tagged species (TS) approach (CAMx with the PSAT module). The study focused on the main sources of secondary inorganic aerosol precursors in the Po Valley (northern Italy): agriculture, road transport, industry and residential combustion. The interaction terms between different sources obtained from a factor decomposition analysis were used as indicators of non-linear PM10 concentration responses to individual source emission reductions. Moreover, such interaction terms were analysed in light of the free ammonia / total nitrate gas ratio to determine the relationships between the chemical regime and the non-linearity at selected sites. The impacts of the different sources were not proportional to the emission reductions, and such non-linearity was most relevant for 100 % emission reduction levels compared with smaller reduction levels (50 % and 20 %). Such differences between emission reduction levels were connected to the extent to which they modify the chemical regime in the base case. Non-linearity was mainly associated with agriculture and the interaction of this source with road transport and, to a lesser extent, with industry. Actually, the mass concentrations of PM10 allocated to agriculture by the TS and BF approaches were significantly different when a 100 % emission reduction was applied. However, in many situations the non-linearity in PM10 annual average source allocation was negligible, and the TS and BF approaches provided comparable results. PM mass concentrations attributed to the same sources by TS and BF were highly comparable in terms of spatial patterns and quantification of the source allocation for industry, transport and residential combustion. The conclusions obtained in this study for PM10 are also applicable to PM2.5.
Formation, evolution, and drainage of short-lived glacial lakes in permafrost environments of the northern Teskey Range, Central Asia
Authors: Daiyrov Mirlan , Narama Chiyuki
Published: July 2021

Abstract. In the Teskey Range of the Tien Shan (Kyrgyz Republic),
five
outburst flood disasters from short-lived glacial lakes in 2006, 2008, 2013, 2014, and 2019 caused severe damages in the downstream part. Short-lived glacial
lakes in the Teskey Range grow rapidly and drain within a few months, due to
closure and opening of an outlet ice tunnel in an ice-cored moraine complex
at the glacier front. In addition to these factors, summer meltwater from
the glacier can cause rapid growth. Outburst floods of this lake type are a
major hazard in this region and differ from the moraine-dam failures common
to the eastern Himalaya. To clarify how short-lived glacial lakes store and
drain water over short periods, we use results from a field survey and
satellite data to analyze the water level, area, volume, and discharge of Korumdu lake (2017–2019) as well as satellite data to monitor the
appearance of 160 other short-lived lakes (2013–2018). Except in 2016,
Korumdu lake appeared and drained within about 1 month during all the
summers. Water level data recorded by a data logger and time-lapse camera
images show that the lake appeared and expanded suddenly from July to August
in 2017–2019. The timing of lake appearance indicates that the lake formed
when an outlet ice tunnel (subsurface channel) drainage was blocked by
depositions of an ice–debris mixture due to ice melting and not by freezing of
stored water. For 2017, we used uncrewed aerial vehicle (UAV)-derived
digital surface models (DSMs) and water levels, finding that the lake's
volume reached 234 000 m3 within 29 d, and then the water discharged
for 17 d at a maximum rate of 0.66 m3/s. This discharge rate is more
than 20 times smaller than those found earlier (2006–2014) for four
short-lived lakes of tunnel type in this region. We argue that this large variation in
discharge rates is due to variation in the dimensions of the outlet
ice tunnels. For the 160 other short-lived glacial lakes, we found that 117
formed during the ice-melt period from July to September. This timing and
our findings for Korumdu lake show that these 117 lakes likely formed
primarily because deposition of an ice–debris mixture blocked the outlet
tunnel, though increased glacial melt would also have contributed. In the
Teskey Range, the appearance of short-lived glacial lakes on the moraine
complexes at glacier fronts is inevitable in summer when the melting rate is
high. Similar behavior of short-lived lakes may occur in other mountain
regions of Central Asia, such as the Tien Shan and Pamir Mountains, wherever
ice-cored moraine complexes exist within mountain permafrost zone. Moreover,
increasing temperatures may increase both tunnel size and lake-basin size
(lake volume), leading to increased hazard potential from such lakes in the
future.
Comparing estimation techniques for temporal scaling in palaeoclimate time series
Authors: Hébert Raphaël , Rehfeld Kira , Laepple Thomas
Published: July 2021

Abstract. Characterizing the variability across timescales is important for understanding the underlying dynamics of the Earth system. It remains challenging to do so from palaeoclimate archives since they are more often than not irregular, and traditional methods for producing timescale-dependent estimates of variability, such as the classical periodogram and the multitaper spectrum, generally require regular time sampling. We have compared those traditional methods using interpolation with interpolation-free methods, namely the Lomb–Scargle periodogram and the first-order Haar structure function. The ability of those methods to produce timescale-dependent estimates of variability when applied to irregular data was evaluated in a comparative framework, using surrogate palaeo-proxy data generated with realistic sampling. The metric we chose to compare them is the scaling exponent, i.e. the linear slope in log-transformed coordinates, since it summarizes the behaviour of the variability across timescales. We found that, for scaling estimates in irregular time series, the interpolation-free methods are to be preferred over the methods requiring interpolation as they allow for the utilization of the information from shorter timescales which are particularly affected by the irregularity. In addition, our results suggest that the Haar structure function is the safer choice of interpolation-free method since the Lomb–Scargle periodogram is unreliable when the underlying process generating the time series is not stationary. Given that we cannot know a priori what kind of scaling behaviour is contained in a palaeoclimate time series, and that it is also possible that this changes as a function of timescale, it is a desirable characteristic for the method to handle both stationary and non-stationary cases alike.
TINKERPLOTS MODEL CONSTRUCTION APPROACHES FOR COMPARING TWO GROUPS: STUDENT PERSPECTIVES
Authors: NOLL JENNIFER , KIRIN DANA
Published: July 2021

Teaching introductory statistics using curricula focused on modeling and simulation is becoming increasingly common in introductory statistics courses and touted as a more beneficial approach for fostering students’ statistical thinking. Yet, surprisingly little research has been conducted to study the impact of modeling and simulation curricula on student thinking, nor is there much research on how students make sense of the computer models they construct. The work presented here utilizes a framework developed by Biehler, Frischemeier, and Podworny (2015) for comparing two groups problems via a modeling and simulation approach using TinkerPlotsTM. Our work makes a contribution to the field by delving deeper into student reasoning as students create TinkerPlotsTM models to solve a comparing two groups problem.

Published: July 2021

Connecting data and chance is fundamental in statistics curricula. The use of software like TinkerPlots can bridge both worlds because the TinkerPlots Sampler supports learners in expressive modeling. We conducted a study with elementary preservice teachers with a basic university education in statistics. They were asked to set up and evaluate their own models with TinkerPlots by using a real and open dataset they were given. In this article we present students’ processes of setting up and evaluating their models and focus on their reasoning during this process.

PERSONAL EPISTEMOLOGIES OF STATISTICIANS IN ACADEMIA: AN EXPLORATORY STUDY
Authors: DIAMOND AUREL H. , STYLIANIDES ANDREAS J.
Published: July 2021

In this exploratory study, we investigated the personal epistemologies of statisticians in academia with the aim of offering some insight into what might be an availing epistemology for learning statistics. Findings from in-depth, semi-structured interviews with six academics in the UK currently researching within the field of statistics showed that their statistical personal epistemologies were consistent with constructivist theories of learning. Based on these findings, we proposed an integrated model to represent participants’ beliefs about knowledge and knowing in statistics. Furthermore, we found differences between participants’ mathematical and statistical personal epistemologies, and we offered an argument for domain-specificity of personal epistemologies. The implications of our findings for research in statistics education and statistical misconceptions are discussed.

Published: July 2021

This paper describes a qualitative survey of professional statisticians carried out in New Zealand in 2014. The aim of the study was to find out if the issues this group faced were consistent with those identified in the literature. The issues identified were integrity, legitimacy, isolation, workforce shortage, communication, and marginalisation. They represent points of frustration for statisticians that may impact on the future of the profession as it responds to increasing demands and higher expectations. We found that these issues resonated for many of the statisticians included in our study and we have discussed a number of strategies to address them. They include raising our profile, attracting a broader range of people to the profession, increasing our communication skills, raising the statistical literacy of the people we work with, and a commitment to making it easy to engage with our colleagues.

THE IMPACT OF A FLIPPED CLASSROOM MODEL OF LEARNING ON A LARGE UNDERGRADUATE STATISTICS CLASS
Authors: NIELSEN PERPETUA LYNNE , BEAN NATHAN WILLIAM , LARSEN ROSS ALLEN ANDREW
Published: July 2021

We examine the impact of a flipped classroom model of learning on student performance and satisfaction in a large undergraduate introductory statistics class. Two professors each taught a lecture-section and a flipped-class section. Using MANCOVA, a linear combination of final exam scores, average quiz scores, and course ratings was compared for the two groups after controlling for the effects of students’ previous achievement, gender, teacher, degree of learner autonomy, and attitudes about math and statistics. The results show significant improvement in the students’ performance and course satisfaction with the flipped classroom. Overall, the results showed that the flipped classroom model can be used in large lecture classes with the help of undergraduate teaching assistants and the use of additional labs.

FACILITATING LANGUAGE-FOCUSED COOPERATIVE LEARNING IN INTRODUCTORY STATISTICS CLASSROOMS: A CASE STUDY
Authors: CAREY MICHAEL D. , DUNN PETER K.
Published: July 2021

With the GAISE emphasis on prioritising concept development over mathematical calculation in statistics education, statistical language has increasingly become the focus of research. Yet, there is a dearth of research investigating techniques to teach statistical language. To redress this gap, we introduced a group of statistics tutors to some cooperative learning techniques commonly used to teach language and concepts in other disciplines (Jigsaw and Think-Pair-Share). The twofold aim was to explore the tutors’ uptake of the techniques and how to improve their proficiency in implementing the techniques. The techniques were delivered experientially with tutors through a professional development session followed by implementation of the techniques in their tutorials. A semester-long exploratory case study was conducted using surveys, focus group sessions and shared self-reflection on a digital discussion board. From the tutors’ reported experience and feedback, areas for improvement in the implementation of the techniques were identified, pertaining to the effectiveness of the techniques, expectations of teacher and student roles in learning, and classroom management. Plans for addressing these areas for improvement in future studies are presented, which include enhancing the professional development and adding in-class mentoring of tutors.

USING ATTITUDES AND ANXIETIES TO PREDICT END-OF-COURSE OUTCOMES IN ONLINE AND FACE-TO-FACE INTRODUCTORY STATISTICS COURSES
Authors: ZIMMERMAN WHITNEY ALICIA , AUSTIN STEFANIE R.
Published: July 2021

An abbreviated form of the Statistics Anxiety Rating Scale (STARS) was administered to online and face-to-face introductory statistics students. Subscale scores were used to predict final exam grades and successful course completion. In predicting final exam scores, self-concept, and worth of statistics were found to be statistically significant with no significant difference by campus (online versus face-to-face). Logistic regression and random forests were used to predict successful course completion, with campus being the only significant predictor in the logistic model and face-to-face students being more likely to successfully complete the course. The random forest model indicated that self-concept and test anxiety were overall the best predictors, whereas separately test anxiety was the best predictor in the online group and self-concept was the best predictor in the face-to-face group.

Published: July 2021

A growth mindset emphasizes the malleability of intelligence. The purpose of this pilot study was to implement and evaluate a growth mindset intervention for graduate students. Participants were twenty graduate students recruited from an introductory public health biostatistics class. Students were assessed three times during one semester. At each time point, students completed assessments of growth mindset, grit, social and emotional health, and attitudes toward statistics. Student grades were collected from the course instructor. Descriptive results indicate that growth mindset, grit, and social and emotional health fluctuated little over time. Mean scores for four attitudes toward statistics components improved over time. We found limited relationships between growth mindset and final grades. Growth mindset-based strategies may be more impactful at a persona, rather than academic, level.

DEVELOPING A STATISTICAL LITERACY ASSESSMENT FOR THE MODERN INTRODUCTORY STATISTICS COURSE
Authors: ZIEGLER LAURA , GARFIELD JOAN
Published: July 2021

The purpose of this study was to develop the Basic Literacy In Statistics (BLIS) assessment for students in an introductory statistics course, at the postsecondary level, that includes, to some extent, simulation-based methods. The definition of statistical literacy used in the development of the assessment was the ability to read, understand, and communicate statistical information. Multiple instruments were available to assess students in introductory statistics courses; however, there were no assessments available that focused on statistical literacy. Evidence of reliability and validity were collected during the development of the assessment. Evidence of reliability and validity was high; however, more items with high difficulty levels could increase the precision in estimating ability estimates for higher achieving students.

Teaching undergraduate psychology statistics poses challenges to instructors and students due to the perceived complexity of the material and lack of student motivation. With the goal of boosting student competency and engagement in statistics, our study introduced a gamified learning environment into the laboratory portion of the undergraduate psychology statistics course in which the gamified learning group was compared to the traditional group. Changes in intrinsic motivation, perceived competence, and objective pre- and post-test course content were assessed. Objective posttest scores were positively associated with perceived competence in statistics for the gamified learning group. Perceived competence is a strong predictor of achievement and foundational prerequisite of intrinsic motivation, suggesting that in contrast with the traditional group, students in the gamified group were further on the path towards developing intrinsic motivation and improved scholastic achievement.

On representing autism and the altruism of self-reflexive writing
Authors: Sutherland Katie
Published: July 2021

Autoethnographic stories about illness and disability are usually written for, and with,

readers in mind, engaging in the ’reciprocity that is storytelling (whereby) the teller

offers herself as a guide to the other’s self-formation’ (Frank 1995: 17–8). While selfreflexive narratives can be immensely healing for the writer, they also invite readers

to reflect upon the issues at hand and bring about a shift in their own thinking. As

such, self-reflexive writing can be a powerful tool for advocacy and for challenging

the status quo. By allowing readers to empathise and connect with the subject matter

at a very personal level, it can illuminate nuanced moments of adversity or insight,

and capture a depth of understanding that more traditional texts may not always

depict. This article draws on interviews with families living with high functioning

autism and the exemplar text _Far from the tree: Parents, children and the search for

identity_ (Solomon 2014). Following Solomon, the article’s author reflects upon

personal experiences and embraces self-reflexivity as a way of better understanding

herself, representing her subjects, and helping to illuminate a common theme that

difference is a value worth nurturing.
Nurse as wounded healer in The English Patient
Authors: McAllister Margaret
Published: July 2021

The English Patient, a novel by Michael Ondaatje (1993), is a romantic drama set in the

chaos of Europe at the end of World War II. In the ruins of an Italian church, a terribly

burned man is being tended to by Hana, a young nurse too traumatised from her own war

experiences to return home. Ondaatje’s acclaimed novel contains rich imagery, complex

characters and interactions, as well as a story that weaves back and forward in time. The

novel is a writerly text; the meaning needs to be unravelled by the reader and, due to this

feature, it also makes for interesting reading about nursing. Too often texts about nursing

are reductionist and stereotyped – nurse characters are often angels or lovers, sometimes

villains and sleuths. Rarely are they portrayed as a wounded healer – an ancient,

intriguing and illuminating myth. Within this paper, Hana’s struggles are read as a

metaphor for those that similarly confront many nurses. She is a vulnerable young person

thrust, because of the nature of her work, into the harsh realities of adulthood. She aspires

to a kind of nursing that is attendant and gentle, and able to meet all of her patient’s

needs. Yet the world she is forced to work in is chaotic, unpredictable and stripped of

resources. The patient she tries to comfort is moribund and he endures agony and loss.

In her interactions with him she learns about love, beauty, humility and, ultimately,

resilience. In this way the written, literary narrative connects to a cultural narrative that

at once embodies a profession’s struggles and illuminates more general transcendence.

Narratives of mental health nursing in the emergency department
Authors: Price Toby , McAllister Margaret
Published: July 2021

The telling, listening to, and re-telling of stories is a fundamental human activity. In the

mental health context, storytelling can take on another layer of meaning, when clinicians

begin to be more conscious of the stories they hear, recall these, and then re-tell them to

their clients and carers. This process has many benefits. It helps to clarify communication

between someone who may not be very trusting, with another who may not fully

understand; and it can reconnect mental health clinicians with a deeply embedded

cultural value that can be overwhelmed by the bio-medical approach – professional

empathy. This article argues that the conscious use of re-storying, an aspect of Story

Theory, can extend mental health nursing practice, deepening the quality of the

interpersonal relationship so that the patient, family and nurse can mutually achieve

greater understanding of needs and goals, and transform a crisis into a turning point. This

suggests that stories shared, reflected upon and re-storied are not only relevant in creative

practice terms, but can also contribute to health and wellbeing.
Integrarea socială – factor al securității și stabilității dinamice al sistemului politic european
Authors:   Academia de Administrare Publică, Republica Moldova, Roșca Ludmila
Published: July 2021

În prezentul articol, autorul cercetează diferite posibilităţi de integrare socială a persoanelor, grupurilor sociale, indicând cauza marginalizării – nivelul redus al culturii, al capacităţii de comunicare, al cunoaşterii de sine. Indiferent de statutul social al persoanei: om sărac, angajat, şomer sau imigrant, incluziunea socială este stimulată de interesul persoanei de a cunoaşte, de a acţiona, de a se manifesta. Integrarea socială poate şi trebuie stimulată și de instituţiile statului. În caz contrar, nemulţumirea marginalizaţilor va conduce la destabilizarea sistemului politic, la conflicte sociale. Integrarea socială a imigranţilor este o modalitate de diminuare a crizei sociale, pe care fenomenul l-a produs în statele europene. Obiectivele-cheie ale investigației sunt: analiza provocărilor la securitatea şi instabilitatea sistemului politic al statelor europene; definirea integrării şi incluziunii sociale ca factor al stabilităţii dinamice a sistemului politic; Interpretarea marginalizării ca factor destabilizator; analiza integrării sociale a imigranţilor prin cunoaştere şi comunicare.
Identificări conceptual-teoretice ale relației ,,paradiplomație - politică externă”
Authors:   Universitatea de Stat din Moldova, Cebotari Svetlana
Published: July 2021

Deși fenomenul paradiplomațe a apărut în anii 1970, abia la începutul sec. XXI acest concept a devenit prezent în cercetările științifice și în discursurile politicienilor. Acest termen a fost inventat pentru a desemna activitățile internaționale ale instituțiilor necentrale ale unui stat: municipalități, regiuni, companii private etc. Pornind de la raționamentul conform căruia politica externă reprezintă activitatea statului în afacerile internaţionale sau activitatea statului pe arena internaţională, fenomenul ,,paradiplomație” la fel desemnează activitatea internațională a regiunilor sau blocurilor regionale transnaționale, companiilor private, municipalităților, etc. Prezentul articol are drept scop reliefarea corelației prezente între conceptul de ,, paradiplomație” și ,,politică externă”.
Provocările conflictului transnistrean pentru securitatea națională și vectorul de dezvoltare european al Republicii Moldova
Authors:   Academia de Administrare Publică, Republica Moldova, Ciobanu Natalia
Published: July 2021

În acest studiu autorul își propune să cerceteze eventuale amenințări ce afectează securitatea națională a Republicii Moldova în contextul ignorării statutului de neutralitate al țării de către Federația Rusă, fapt argumentat de tergiversarea procesului de reglementare politică a conflictului transnistrean, determinat de existenţa ilegală a forţelor militare ruse, finanţarea instituțiilor nelegitime din stânga Nistrului și a structurilor militare separatiste, inclusiv cu armament şi tehnică militară. Analizând aceste aspecte, autorul subliniază în mod deosebit faptul că procesul consolidării stabilității și securității unui stat vulnerabil pe interior este migălos și necesită atât eforturi din partea instituțiilor statului, a întregii societăți, cât și susținere internațională. În acest sens, Republica Moldova s-a angajat să aprofundeze relațiile cu Uniunea Europeană, semnând în iunie 2014 Acordul de Asociere, care prevede printre altele și intensificarea formatelor de colaborare axate pe interese comune în domeniul promovării securităţii, cooperării în domeniul apărării şi gestionării crizelor, acceptând astfel provocările alinierii la standardele de dezvoltare a spațiului comunitar, beneficiind totodată de suportul partenerilor de dezvoltare în diverse dimensiuni: politice, economice, sociale etc. În concluzie, autorul constată faptul că în parcursul de colaborare, pentru Uniunea Europeană este relevant să-i fie asigurată securitatea. Astfel, interesele interne al Republicii Moldova ce țin de anumite riscuri și amenințări la securitatea națională sunt convergente cu cele ale uniunii. Uniunea Europeană susține politic și financiar acțiunile ce sunt întreprinse pentru elucidarea acestora, dar responsabile de rezultatele acestor acțiuni/inacțiuni sunt în exclusivitate instituțiile statului moldovenesc.
Cultura de securitate dezvoltată prin educație
Authors:   Academia de Administrare Publică, Republica Moldova, Curoș Ludmila
Published: July 2021

Articolul dat aduce argumente în necesitatea dezvoltării culturii de securitate, care trebuie să constituie un reper de conduită, moral, educativ și formativ; promovării ansamblului de informații, atitudini, convingeri și valori prin care individul le raportează la sistemul politic, militar și economic, care caracterizează nivelul de asigurare a securității fiecărui individ în parte și a întregii societăți. Nevoia dezvoltării culturii de securitate și a educării populației în acest spirit derivă din diversificarea amenințărilor la adresa securității naționale și a modului de propagare a acestora. Educarea și promovarea unei culturi de securitate solidă va preveni transformarea vulnerabilităților în amenințări la adresa securității naționale. Din motivul că la baza dezvoltării culturii de securitatea stau cetățenii, educația în domeniul dat aduce un aport considerabil în promovarea corectă a culturii respective la toate nivelele de învățământ, bazându-ne pe principiul învățământului pe tot parcursul vieții. Actorii preocupați de realizarea educației de securitate, utilizează mai multe mijloace de instruire prin intermediul unor acțiuni concrete, precum: întâlniri cu reprezentanți ai societății civile, mese rotunde, conferințe, dezbateri sau diverse parteneriate cu instituții academice sau de cercetare, sesiuni de comunicări științifice, întâlnirii cu elevii și studenții din instituțiile de învățământ de orice nivel, treninguri cu tinerii activi, introducerea unităților de curs privind dezvoltarea culturii de securitate , cu toate componentele sale, de la modul sănătos de viață și dezvoltarea personală la protecția munci, protecția civilă, educație pentru societate, etc. Așadar, cultura de securitate este vitală în era informațională pe care o traversăm, în care cu toții avem nevoie de repere de orientare atât la nivel personal, cât și la nivel statal. Un cetățean cu o înaltă cultură de securitate este partenerul natural și de neprețuit pentru comunitatea din care face parte și pentru națiune.

Published: July 2021

В статье рассматриваются вызовы, угрозы и риски продовольственной безопасности Молдовы в контексте обеспечения населения страны продовольствием. Отмечается, что угрозы обеспечения продовольственной безопасности в Молдове в настоящее время возросли и сопряжены с политическими и макроэкономическими, социальными и торгово-экономическими, природными и техногенными, технологическими и агроэкологическими вызовами и угрозами. Делается вывод, что продовольственная безопасность Молдовы на современном этапе не обеспечена; требуются качественное преобразование молдавского сельскохозяйственного производства, повышение его эффективности производства сельскохозяйственной продукции и продовольствия с целью обеспечения потребностей внутреннего рынка в собственном продовольствии.
Experiența româniei în gestionarea politicilor migraționiste

Published: July 2021

Numărul românilor de pretutindeni este estimat în prezent la aproape 10 milioane - inclusiv românii care trăiesc în comunitățile din diaspora și cei care trăiesc în comunitățile istorice/ tradiționale ale țărilor din vecinătatea României. Statisticile oficiale ale României și ale altor state sau ale instituțiilor internaționale sunt indicatori utili, dar nu surprind statisticile realității, fie din cauza periodicității cu care sunt realizate, fie din cauza reticenței autorităților față de prezentarea cifrelor reale privind minorități.
Aspecte conceptuale privind domiciliul și reședința persoanei fizice (partea II)
Authors:   Universitatea de Stat din Moldova, Curchin Renat CURCHIN
Published: July 2021

Conceptul de domiciliu urmează a fi cercetat atât prin prisma reglementărilor naționale, cât și a celor internaționale, deoarece acest termen nu are aceiași semnificație, or aplicarea termenului este mult mai largă și nu urmează a fi identificată cu noțiunea de „locuință” în sensul dreptului de proprietate asupra unui imobil. Importanța stabilirii domiciliului sau a reședinței temporare este determinată de efectele juridice pe care le produce din punct de vedere a dreptului constituțional, civil, penal, familiei ș.a. Prezentul demers științific, divizat în două părți, reprezintă o încercare de definire a termenilor de bază, identificarea situațiilor de determinare a domiciliului în cazul persoanelor minore, a persoanelor ocrotite, regulile și excepțiile reglementate atât la nivel național, cât și internațional.
Social integration as security and dynamic stability factor of the European political system
Authors:   Academy of Public Administration, Republic of Moldova, Rosca Ludmila
Published: July 2021

In the article, the looks into different possibilities of social integration of people, social groups, pointing to the cause of marginalization – the low level of culture, communication capacity, selfknowledge. Regardless of the social status of the person: poor, employed, unemployed or immigrant, social inclusion is stimulated by the individual’s interest in knowing, acting, and manifesting himself. Social integration can and must be stimulated by state institutions, as well. Otherwise, dissatisfaction among the marginalized will lead to destabilization of the political system and social conflicts. The social integration of immigrants is a way of mitigating the social crisis that has occurred in European countries. The key objectives of the investigation are: to analyze the challenges to the security and instability of the political system of the European States; to define social integration and inclusion as a factor of the dynamic stability of the political system; to interpret marginalization as a destabilizing factor; to analyze the social integration of immigrants through knowledge and communication.
