Koncepcja efektów mnożnikowych w wyznaczaniu wpływu przedsiębiorstw na otoczenie społeczno-gospodarcze
Authors: Wiedermann Krzysztof
Published: March 2021

The subject of this paper is presentation of a method of calculating multiplier effects in order to determine the influence of enterprises on their environment. Emergence or development of economic activity in a given area may bring about an increase in income and employment in many other enterprises, as well as to an increase taxes collected by the local authority. This increase is labelled multiplier effects, and its value enables the evaluation of the enterprise’s activity on the functioning of neighbouring firms.In literature, the most frequently discussed types of multiplier effects are the supply and income effects. The first result from the demand created by the emerging and developing enterprises, which fosters the development of their goods and services suppliers. The second type, the income effects, result from the increase in purchasing power of the inhabitants, owing to the employees’ remuneration, and this means fostering the development of firms that satisfy consumers’ needs. These enterprises create greater demand themselves, thus triggering new cycles of multiplier effects.The calculation of created workplaces for the supply effects was conducted by using a designed algorithm. It allows calculating the new workplaces in the supplier firms on the bases of data concerning income of enterprises, participation of supply in the revenue, and employment-related costs. The growth of employment and payment is correlated with the increase in the income multiplier effects, generated by single enterprises. This work presents a scheme for calculation of new workplaces created as a result of new investments.

Wpływ kryzysu na wielkość pasażerskiego ruchu lotniczego na świecie na podstawie wybranych przykładów
Authors: Rettinger Renata , Staszak Piotr
Published: March 2021

Recent years have witnessed a whole range of changes in the global economic system; the changes have largely resulted from crisis situations in global markets. Air transport is an element of the system that is very sensitive to any kinds of changes. Due to a difficult financial situation the sector is relatively quickly affected. The corporate representatives and individuals in situation of financial crisis can easily resign from air transportation, especially for short distance travel. The main purpose of the paper is to present changes in passenger’s air transport quantity in the largest airports of the world with respect to the selected air carriers. The first part of the article presents the size of passenger’s air transport in the airports with the highest number of passengers (Atlanta Hartsfield-Jackson, London Heathrow, Frankfurt International) in years 2007−2010, i.e. since the moment preceding the global trend of decrease in air transportation till now (in accordance with the current availability of statistic data). Next, the changes in passenger’s air transportation quantity for the selected air carriers operating in various parts of the world have been analyzed with respect to a comparable period of time. In the last part of the paper the authors tried to present the examples of the impact of crisis on particular air carriers as well as to discuss the attempts undertaken to restore the passenger’s transportation rates to the level preceding the crisis.
Usługi edukacyjne na poziomie akademickim w kontekście wymagań rynku pracy
Authors: Piróg Danuta
Published: March 2021

The transformation of the political system in Poland brought, apart from obvious profits, a number of negative consequences. One of the crucial socio-economic problems is unemployment, which also affects the graduates of higher education. One of the most important reasons for this unfavourable situation is traditional concept of academic education, not always correlating with the needs of employers. Previous curricula  strategies resulted in some majors being perceived as a pass to low paid occupations or unemployment. According to many scholars, thinking about academic education mainly as the step for being employed after graduation is oversimplifying the role of higher education. This outlook does not take into consideration very dynamic changes in services (also educational services on an academic level) in socio-economic development and the fact that one of the  principal purposes of modern higher education is to produce graduates who are able to succeed in the workplace and who can make worthwhile contributions to organisations where they are employed. Such aspirations are common for candidates for students who estimate the probability of finding a good job after graduation. The experiences of the West European countries in this area show that in few years it will be very important to design such curricula which provide education as close to employers’ expectations of the graduates as possible. The paper presents the results of the literature studies concerning modern concepts of higher education in reference to the needs of the labour market.

Energetyka odnawialna Unii Europejskiej w warunkach kryzysu gospodarczego
Authors: Pach-Gurgul Agnieszka
Published: March 2021

Współcześnie wykorzystywanie energii odnawialnej zarówno w Unii Europejskiej (UE), jak i na całym świecie wydaje się nieuniknione z wielu powodów. Jednym z podstawowych są korzyści ekologiczne związane z uniknięciem emisji gazów cieplarnianych. Kolejnym jest zwiększenie bezpieczeństwa energetycznego UE poprzez dywersyfikację dostaw energii i decentralizację jej wytwarzania. Ponadto wykorzystanie energii odnawialnej ogranicza zapotrzebowanie na surowce konwencjonalne, takie jak ropa, gaz czy węgiel. W przypadku wykorzystywania odnawialnych źródeł energii nie występuje problem ich wyczerpywania się, a co za tym idzie odnawialności zasobów. Te wszystkie atuty nabierają coraz większego znaczenia w Unii Europejskiej, zwłaszcza w dobie rosnących cen surowców energetycznych, powtarzających się kryzysów gazowych czy dekarbonizacji gospodarki. Kryzys gospodarczy wywołał jednak dyskusję w całej Unii Europejskiej na temat kosztów związanych z produkcją energii elektrycznej z odnawialnych źródeł energii. Walka z bezrobociem i długiem publicznym, a także spadająca konkurencyjność unijnej gospodarki, która powiązana jest z wysokimi kosztami energii elektrycznej, postawiła wiele krajów (nawet liderów w tej branży) w sytuacji przymusu ograniczenia wsparcia dla tych źródeł energii i wyhamowania tempa ich rozwoju.
Europejskie uwarunkowania rozwoju sektora małych i średnich przedsiębiorstw w Polsce
Authors: Wieloński Andrzej , Szmigiel Katarzyna
Published: March 2021

Cechą charakterystyczną gospodarki Unii Europejskiej jest znaczący w niej udział sektora małych i średnich przedsiębiorstw – MSP. Przedsiębiorstwa te, w porównaniu z przedsiębiorstwami dużymi, w tym zwłaszcza spółkami akcyjnymi, są słabszymi podmiotami gospodarczymi. Ich znacznie mniejsze możliwości pozyskiwania kapitału i zaawansowanych technologii powodują, że są w dużym stopniu zagrożone upadłością. Jednak dzięki aktywnej polityce wspierania prywatnej przedsiębiorczości liczba nowo powstających przewyższa liczbę tych, którym się nie powiodło (Leśniewski 2003). Polityka ta opiera się na założeniu, że sektor MSP przyczynia się do powstawania klasy średniej, której istnienie jest warunkiem stabilnej demokracji oraz przeciwdziała procesom koncentracji w gospodarce rynkowej i jej monopolizacji, ograniczającym wolny wybór i konkurencję (Ważniewski 2003).

Sekuritisasi China Fine Dust oleh Pemerintah Korea Selatan terhadap Tiongkok
Authors: Nabila Eryolanda Putri
Published: March 2021

China Fine Dust issue has emerged in 2013 and increase in 2014 so that South Korea suffered from the impact. Meanwhile, China as a contributor of the haze refuses to take responsibility for tackling this issue, so that South Korea must securitize. This study aims to describe the process of securitization of China Fine Dust issue carried out by South Korea to China by using the concept of securitization by Barry Buzan as an analytical framework. The research method used is a qualitative method with a descriptive approach. The data used in this research was collected through literature study. The securitization process carried out by the South Korean Government against China began with South Korea carrying out a scientific agenda to identify a threat with China's initial involvement of 48%. Then political agenda, which are three points; influencing the public to gain support, forming a domestic emergency policy, holding a bilateral meeting to convince China to work together because domestic actions are not enough yet. The continuation of political management shows that the agenda of securitization carried out by South Korea made China accept the issue as a threat and agreed to cooperate in tackling the haze issue by releasing several projects.
En quoi l’histoire de l’être de Heidegger est-elle phénoménologique ?
Authors: Slama Paul
Published: March 2021

Dans cet article, on tente d’expliciter ce qu’il faut entendre par « histoire de l’être » chez Heidegger en termes phénoménologiques, puisqu’il n’a jamais rompu avec cette tradition, même dans la phase la plus radicale de sa pensée. On montre que l’histoire de l’être possède les trois caractéristiques fondamentales de la méthode phénoménologique : donation, intuition, et réduction, et que cela implique une compréhension conceptuelle de l’histoire en général (même la plus matérielle), puisqu’elle est gouvernée par l’histoire de la métaphysique, c’est-à-dire l’histoire des grands concepts de la tradition métaphysique. On met ensuite en évidence cette compréhension de l’histoire au moyen du débat de Heidegger avec Marx, et d’Adorno avec Heidegger : la position phénoménologique trouve son interlocuteur le plus critique dans le matérialisme historique qui fait reposer non seulement l’histoire sur les processus économiques de production, mais également le discours métaphysique (dont celui de Heidegger) sur des processus non moins matériels. C’est ainsi à la lumière de ce débat entre phénoménologie et matérialisme qu’on interprète l’histoire de l’être.
Normativité et intentionnalité : pour un pluralisme normatif
Authors: Desmeules Marie-Hélène
Published: March 2021

Brentano et Husserl reconnurent tous deux que certaines de nos intentionnalités posent des enjeux normatifs. Seulement, Brentano croyait que les intentionnalités ne peuvent être qualifiées normativement que si elles sont incompatibles avec une autre façon opposée de se rapporter intentionnellement à un même objet. Husserl insista pour sa part sur le fait qu’il n’y a des enjeux normatifs que là où il y a une relation intentionnelle et positionnelle. Malgré cette distinction, en imposant ces conditions (incompatibilité et position) pour qu’il soit question de normativité intentionnelle, Brentano et Husserl se trouvèrent tous deux à favoriser un réductionnisme normatif. Je proposerai pour ma part, dans un geste rappelant celui de la pragmatique d’Austin mais sans m’y restreindre pour autant, de dépasser ce réductionnisme normatif en cessant de limiter à ces conditions l’application de normes à nos intentionnalités.
Distillation protocols for Fourier states in quantum computing
Authors: Jones Cody
Published: March 2021

Fourier states are multi-qubit registers that facilitate phase rotations in fault-tolerant quantum computing. We propose distillation protocols for constructing the fundamental, $n$-qubit Fourier state with error $O(2^{-n})$ at a cost of $O(n \log n)$ Toffoli gates and Clifford gates, or any arbitrary Fourier state using $O(n^2)$ gates. We analyze these protocols with methods from digital signal processing. These results suggest that phase kickback, which uses Fourier states, could be the current lowest-overhead method for generating arbitrary phase rotations.
Uselessness for an Oracle model with internal randomness
Authors: Harrow Aram W. , Rosenbaum David J.
Published: March 2021

We consider a generalization of the standard oracle model in which the oracle acts on the target with a permutation selected according to internal random coins. We describe several problems that are impossible to solve classically but can be solved by a quantum algorithm using a single query; we show that such infinity-vs-one separations between classical and quantum query complexities can be constructed from much weaker separations. We also give conditions to determine when oracle problems -- either in the standard model, or in any of the generalizations we consider -- cannot be solved with success probability better than random guessing would achieve. In the oracle model with internal randomness where the goal is to gain any nonzero advantage over guessing, we prove (roughly speaking) that k quantum queries are equivalent in power to 2k classical queries, thus extending results of Meyer and Pommersheim.
Classical simulation complexity of extended Clifford circuits
Authors: Jozsa Richard , Van den Nest Marrten
Published: March 2021

Clifford gates are a winsome class of quantum operations combining mathematical elegance with physical significance. The Gottesman-Knill theorem asserts that Clifford computations can be classically efficiently simulated but this is true only in a suitably restricted setting. Here we consider Clifford computations with a variety of additional ingredients: (a) strong vs. weak simulation, (b) inputs being computational basis states vs. general product states, (c) adaptive vs. non-adaptive choices of gates for circuits involving intermediate measurements, (d) single line outputs vs. multi-line outputs. We consider the classical simulation complexity of all combinations of these ingredients and show that many are not classically efficiently simulatable (subject to common complexity assumptions such as P not equal to NP). Our results reveal a surprising proximity of classical to quantum computing power viz. a class of classically simulatable quantum circuits which yields universal quantum computation if extended by a purely classical additional ingredient that does not extend the class of quantum processes occurring.
On the geometry of stabilizer states
Authors: Garcia Hector J. , Markov Igor L. , Cross Andrew W.
Published: March 2021

Large-scale quantum computation is likely to require massive quantum error correction (QEC). QEC codes and circuits are described via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them. Such states are obtained by {\em stabilizer circuits} (consisting of CNOT, Hadamard and Phase gates) and can be represented compactly on conventional computers using $\Theta (n^2)$ bits, where $n$ is the number of qubits \cite{Gottes98}. As an additional application, the work in~\cite{Aaron, AaronGottes} suggests the use of superpositions of stabilizer states to represent arbitrary quantum states. To aid in such applications and improve our understanding of stabilizer states, we characterize and count nearest-neighbor stabilizer states, quantify the distribution of angles between pairs of stabilizer states, study succinct stabilizer superpositions and stabilizer bivectors, explore the approximation of non-stabilizer states by single stabilizer states and short linear combinations of stabilizer states, develop an improved inner-product computation for stabilizer states via synthesis of compact canonical stabilizer circuits, propose an orthogonalization procedure for stabilizer states, and evaluate several of these algorithms empirically.
Fault-tolerant renormalization group decoder for abelian topological codes
Authors: Duclos-Cianci Guillaume , Poulin David
Published: March 2021

We present a three-dimensional generalization of a renormalization group decoding algorithm for topological codes with Abelian anyonic excitations that we introduced for two dimensions in \cite{DP09a,DP10a}. We also provide a complete detailed description of the structure of the algorithm, which should be sufficient for anyone interested in implementing it. This 3D implementation extends our previous 2D algorithm by incorporating a failure probability of the syndrome measurements, i.e., it enables fault-tolerant decoding. We report a fault-tolerant storage threshold of $\sim1.9(4)\%$ for Kitaev's toric code subject to a 3D bit-flip channel (i.e. including imperfect syndrome measurements). This number is to be compared with the $2.9\%$ value obtained via perfect matching \cite{H04a}. The 3D generalization inherits many properties of the 2D algorithm, including a complexity linear in the space-time volume of the memory, which can be parallelized to logarithmic time.
A quantum circuit to find discrete logarithms on ordinary binary elliptic curves in depth O(log^2n)
Authors: Rotteler Martin , Steinwandt Rainer
Published: March 2021

Improving over an earlier construction by Kaye and Zalka \cite{KaZa04}, in \cite{MMCP09b} Maslov et al. describe an implementation of Shor's algorithm, which can solve the discrete logarithm problem on ordinary binary elliptic curves in quadratic depth $\bigO(n^2)$. In this paper we show that discrete logarithms on such curves can be found with a quantum circuit of depth $\bigO(\log^2n)$. As technical tools we introduce quantum circuits for ${\mathbb F}_{2^n}$-multiplication in depth $\bigO(\log n)$ and for ${\mathbb F}_{2^n}$-inversion in depth $\bigO(\log^2 n)$.
Long distance entanglement generation through coherent directed transport of Neutral atoms in unmodulated optical lattices
Authors: Rafiee Morteza , Bayat Abolfazl
Published: March 2021

We introduce a fully coherent way for directed transport of localized atoms in optical lattices by regularly performing phase shifts on the lattice potential during the free evolution of the system. This paves the way for realizing a possible cold atom quantum computer in which entangling gates operate by bringing two individual atoms in the proximity of each other and letting them to interact. The speed of our protocol is determined by the tunneling amplitudes of the atoms and thus is much faster than the speed of the dynamics resulted from superexchange interaction in spin chains. Our scheme is robust against possible imperfections and perhaps its main advantage is its simplicity where all of its requirements have been already achieved in recent experiments.
INTERNATIONAL MEASURES TO COUNTERACT THE LAUNDERING OF ILLEGAL INCOME OF THE FIFTH GENERATION – LEGAL CONDITIONS FOR STRENGTHENING THE SECURITY OF THE FINANCIAL MARKET
Authors: Vashchekina I. V. , Vashchekin A. N.
Published: March 2021

The article analyses the development of international agreements on the means of controlling financial activities, concluded to counteract the laundering of proceeds from crime and the financing of terrorism. The study was carried out by analytical methods based on domestic legislation, international agreements and regulations. As a result of thirty years of work on organizing interaction in the developing three-level financial monitoring system, a whole set of measures has developed, the main development trend of which is to reduce information uncertainty. In this regard, the fifth generation of agreements on the limitation of potentially illegal activities in the financial sector, introduced in 2020, is acquiring special importance. The legal entities covered by the restrictive and control measures now include crypto exchange platforms, virtual wallet providers, as well as firms that provide currency exchange services. In a number of areas, information is automatically exchanged about ongoing transactions, as well as about their participants – clients of banks, insurance and brokerage companies, investment funds, in order to prevent aggressive tax planning and make it difficult to access unjustified tax breaks. The paper presents the economic and organizational results of the introduced legal measures.

ANALYSIS OF THE DYNAMICS AND TRENDS IN THE DEVELOPMENT OF MODERN INTERNATIONAL TOURIST MARKET
Authors: Pshenichnyh J. A.
Published: March 2021

Until recently, the tourism sector accounted for a significant share of the world's gross domestic product and provided about 10 % of world employment. In 2020, the global tourism industry faced a serious challenge – a crisis caused by the spread of a new type of virus (COVID-19 pandemic). International tourism has become one of the most affected by COVID-19 pandemic industries. The demand for tourism and hospitality services, which were one of the world's largest sources of foreign exchange earnings and employment in the era of pre-COVID-19, has significantly decreased. Although the future of tourism in an era of COVID-19 pandemic is very uncertain, a study of trends in the international tourism market in a crisis can be used to assess how the industry can recover and survive in the era of COVID-19 pandemic. Based on the statistical data of international organizations, the author studied indicators of international tourist flows, identified the main trends in the development of international tourism at the current stage, assessed the impact on the tourism sector of the COVID-19 pandemic and determined possibilities for its development in the context of the economic crisis, showed prospects for the development of the industry.

Published: March 2021

The vibrational dynamics of pure and methylammonium-doped formamidinium lead iodide perovskites(FAPbI3) has been investigated by high-resolution neutron spectroscopy. For the ?first time, we provide an exhaustive and accurate analysis of the cation vibrations and underlying local structure around the organic moiety in these materials using ?first-principles electronic-structurecalculations validated by the neutron data. Inelastic Neutron Scattering experiments on FAPbI3provide direct evidence of the formation of a low-temperature orientational glass, unveiling thephysico-chemical origin of phase metastability in the tetragonal structure. Further analysis of thesedata provides a suitable starting point to understand and explore the stabilization of the perovskiteframework via doping with small amounts of organic cations. In particular, we ?find that hydrogenbonds in FAPbI3 are strengthened in a synergistic manner as a result of cage deformation inducedby the dynamics of the neighbouring methylammonium cations.

Published: March 2021

Background: Accessing COVID-19 vaccines is a challenge despite successful clinical trials. This burdens the COVID-19 treatment gap, thereby requiring accelerated discovery of anti-SARS-CoV-2 agents. Thus, this study explored the potential of anti-HIV reverse transcriptase (RT) phytochemicals as inhibitors of SARS-CoV-2 non-structural proteins (nsps) by targeting in silico key sites in the structures of SARS-CoV-2 nsps. Moreover, structures of the anti-HIV compounds were considered for druggability and toxicity. 104 anti-HIV phytochemicals were subjected to molecular docking with papain-like protease (nsp3), 3-chymotrypsin-like protease (nsp5), RNA-dependent RNA polymerase (nsp12), helicase (nsp13), SAM-dependent 2’-O-methyltransferase (nsp16) and its cofactor (nsp10), and endoribonuclease (nsp15). Drug-likeness and ADME (absorption, distribution, metabolism, and excretion) properties of the top ten compounds per nsp were predicted using SwissADME. Their toxicity was also determined using OSIRIS Property Explorer. Results: Among the twenty-seven top-scoring compounds, the polyphenolic natural products amentoflavone (1), robustaflavone (4), punicalin (9), volkensiflavone (11), rhusflavanone (13), morelloflavone (14), hinokiflavone (15), and michellamine B (19) were multi-targeting and had the strongest affinities to at least two of the nsps (Binding Energy = -7.7 to -10.8 kcal/mol). Friedelin (2), pomolic acid (5), ursolic acid (10), garcisaterpenes A (12), hinokiflavone (15), and digitoxigenin-3-O-glucoside (17) were computationally druggable. Moreover, compounds 5 and 17 showed good gastrointestinal absorptive property. Most of the compounds were also predicted to be non-toxic. Conclusions: Twenty anti-HIV RT phytochemicals showed multi-targeting inhibitory potential against SARS-CoV-2 nsp3, 5, 10, 12, 13, 15, and 16, and can therefore be used as prototypes for anti-COVID-19 drug design.

Erbium(III) complexes are the most interesting candidates for high-performance single molecule magnets (SMMs) just after dysprosium(III). Herein, we thoroughly explore the underrepresented class of neutral pseudo-tetrahedral erbium(III) SMMs and demonstrate their exceptional slow magnetization dynamics controlled by the Raman relaxation mechanism and the molecular magnetic memory effect in the form of a waist-restricted magnetic hysteresis loop. The influence of the coordinated TEMPO radical on the slow magnetization relaxation performance is also demonstrated and discussed.

Producción cultural huachafa
Authors:   Universidad de Lima, Dreifuss Serrano Cristina
Published: March 2021

La producción cultural contemporánea en nuestro medio se caracteriza por tener múltiples influencias, que dan como resultado productos finales diversos, eclécticos y, en muchos casos, percibidos como inadecuados. Los términos chicha o huachafo designan actitudes, bienes de consumo, productos culturales e, incluso, obras de arte, cuya imagen se remite a las características mestizas de nuestra sociedad. La combinación de tradiciones, caracteres locales, afanes modernizadores y la búsqueda de pertenencia a un entorno global son algunas de las fuerzas que confluyen en los productos mencionados. Al analizar lo huachafo desde un punto de vista tanto formal como social, se busca entender, a través de las manifestaciones cotidianas, culturales y artísticas, cuáles son las razones de fondo y los mecanismos detrás de estas creaciones. Se manifiesta un proceso de adecuación a nuevas condicionantes, así como la construcción de nuestras ciudades contemporáneas. Los productos huachafos son, por un lado, una clave de lectura de quiénes somos. Por otro, se vuelven parte de nuestra cotidianidad y en este diálogo puede darse la construcción de una nueva identidad: la identidad del peruano contemporáneo, que tiene de inga y tiene de mandinga.
¿Por amor al arte? Creación artística y mercado, oportunidades y dificultades
Authors:   Instituto Superior de Artes Visuales Edith Sachs, Laredo María del Carmen
Published: March 2021

En nuestra época, la creación artística local se ha diversificado dejando atrás su uniformidad para dar pase a lo variado y heterogéneo, y a la vez ha visto multiplicado los espacios para su difusión. Estos fenómenos obedecen a múltiples factores, entre los que se encuentra la concepción de los productos artísticos como ofertas que entran en la dinámica del mercado o que se conciben y expresan para comunicar, apoyándose, además, en la tecnología disponible. Basándome en mi experiencia como artista plástica peruana, pretendo reflexionar acerca de los diferentes tipos de arte, específicamente el actual, y las dificultades, límites y exigencias que esta situación plantea a la creación artística local, pero también sobre las oportunidades que ofrece el contacto abierto entre artistas y sociedad, que puede o debería enriquecer los procesos creativos. En suma, las preguntas renovadas son qué es arte y qué se requiere para crear objetos artísticos.
Transitioning Service Design within Government: An exploration of how the role of Service Design within Central Government agencies might benefit from Transition Design as a key artbiter of social change
Authors:   , Westwater Logan
Published: March 2021

This research considers how Transition Design, an emergent design provocation, could be used to grow the role of Service Design within New Zealand Central Government. Leading this investigation is the assertion that currently within Central Government agencies a re-evaluation and re- scoping of the contributions that Service Design can make towards the resolution, mitigation or navigation of the complex social, cultural, political and economic issues these agencies now face is required. This study also asserts that Service Design could play a more impactful role within Central Government as an arbiter of change. To achieve this, the role of Service Design needs to be redefined and service designers’ skills recalibrated. This research considers how Transition Design could be used to achieve this aim.

Transition Design, as a provocation not a manifesto, challenges the existing paradigms which characterise Service Design and illuminates radical pathways for societal transitions to more sustainable futures. This study identifies opportunities within New Zealand Central Government structures, systems and processes to use Transition Design as a model to challenge existing modes and having done so, enable more radical social and environmental change.

A critical component of this research is a series of interviews conducted with Service Design practitioners currently working within or alongside New Zealand Central Government. These interviews were analysed and used to help define areas or stages of Service Design that Transition Design interventions could be tested against. Importantly, these interviews also served to develop new models that illustrated areas in which Transition Design methods or ideologies could be applied within the Central Government context. A second round of interviews critiqued the practical application of Transition Design within current and towards future Service Design practice. Having identified many of the key barriers currently limiting the effectiveness of Service Design and service designers working within Central Government, this research posits that the provocations exhibited within Transition Design will go a long way to enabling the expansion of both Service Design’s role and service designer’s capacities, capabilities in the resolution, mitigation and navigation of the complex social, cultural, political and economic issues that need to be addressed by New Zealand Central Government.

Virtual Reality Based Passive and Active Distraction Methods for the Treatment of Chronic Pain
Authors:   , Wang Jiaheng
Published: March 2021

Chronic pain is ongoing pain lasting for long periods after the initial injury or disease has healed. Chronic pain is difficult to treat and can affect the daily lives of patients. Distraction therapy is a proven way of relieving pain for patients by taking their attention away from the pain. Virtual reality is a platform for distraction therapy by immersing the user visually, aurally, and even somewhat physically in a virtual world detached from reality. There is little research done regarding the effects virtual reality's physical interactions have on pain management. This project aims to evaluate different types of virtual reality interactions for chronic pain patients to determine which is most effective for pain relief. The results found that physical and mental activities in virtual reality are equally effective as each other at reducing pain while the patients are engaged in the content, while the effects of observing relaxing content persists outside of virtual reality. These results inform the design of future virtual reality games targeted at pain management.
Personal Use of Handheld Fetal Doppler Monitors by Women in New Zealand
Authors:   , Honeyman Lyndal
Published: March 2021

This qualitative descriptive study explores what factors are driving women in New Zealand to use handheld fetal Doppler monitors during their pregnancy. This is a little explored phenomenon in the literature, and consensus among health professional bodies is that pregnant women should be discouraged from using a handheld fetal Doppler. One concern health professionals hold is that a pregnant woman may be falsely reassured about the condition of her unborn baby and would delay presentation to her lead maternity carer, culminating in stillbirth or neonatal morbidity and mortality that potentially could have been avoided.

Six women from a major New Zealand city who were between 20- and 39-weeks’ gestation participated in semi-structured interviews. Thematic analysis, as described by Braun and Clarke, was used to generate five main themes and six subthemes. Control was a strong overarching

theme with subthemes of Fertility and Pregnancy Loss, Ultrasound and Doppler anxieties. Fetal feedback with the subtheme of Bonding was another strong theme. The third and fourth themes were Peer-to-peer education and support and Lay knowledge versus professional knowledge with a

subtheme of Lack of research. The final theme was the Woman-Midwife relationship with a subtheme of More support.

Women’s reasons for using a handheld fetal Doppler is for control of their response to the potential of miscarriage. This response is largely one of anxiety, particularly prior to the quickening of the fetus when there is little feedback to prove ongoing fetal life outside of symptoms such as morning sickness. Whilst women gain their information to underpin use of a handheld fetal Doppler via their peer groups in online forums and other internet-based repositories, they are

wanting to enact partnership and shared decision-making with their lead maternity carer (LMC) regarding their use of handheld fetal Doppler monitors in pregnancy.

As technologies advance and become more available to non-health professionals, further exploration of use of handheld fetal Doppler monitors by pregnant women is needed in order to better inform women and midwives around the potential benefits and risks.
Reef: Drawing in the Expanded Field
Authors: Twose Simon , Globa Anastasia , Harvey Lawrence , Moloney Jules
Published: March 2021

In this article we introduce a body of research on drawing in the extended field and discuss a recent outcome – Reef, an installation at the Tin Shed gallery, Sydney. The research agenda has evolved from architectural sketch drawing. The research extends the open, evocative capacity of drawing through experimental installation art works, deploying sculptural sketch objects, VR, AR and soundscapes. Reef is the second in a series exploring the landscape phenomena of seismic shock. It is a sketch of a section of seabed in Kaikōura, Aotearoa New Zealand.
Emergência e reconhecimento de um problema a investigar em modelagem matemática por alunos do Ensino Fundamental
Authors: Santos Silvia Regina Potulski dos , Veronez Michele Regiane Dias
Published: March 2021

No presente estudo direcionamos o nosso olhar para o modo como emerge um problema a ser investigado em atividades de modelagem matemática, e consideramos que a problematização de uma situação de interesse dos alunos oportuniza ao professor debater acerca de aspectos da realidade deles e de conhecimentos diversos, para além de conceitos matemáticos, ao buscarem por soluções para o problema que rege o desenvolvimento da atividade de modelagem matemática. Com o propósito de investigar que aspectos levam os alunos a reconhecerem um problema a investigar em atividades de modelagem matemática, além de apresentarmos nossas considerações sobre a Modelagem Matemática com alusão ao problema, trazemos para discussão duas atividades de modelagem matemática desenvolvidas por alunos do Ensino Fundamental. A opção metodológica que fundamenta nosso estudo é a abordagem qualitativa, sendo os materiais de análise constituídos das transcrições das gravações em áudio das aulas e dos registros escritos dos alunos e da professora. Com base nas ações e argumentações dos alunos inferimos que, em uma atividade de modelagem matemática, o problema emerge e se sustenta segundo dois aspectos: pela curiosidade dos alunos associada ao envolvimento deles para com o tema em estudo; pela intervenção do professor durante o desenvolvimento das atividades.
Investigating Market and Regulatory Forces Shaping Artificial Intelligence Adoptions
Authors: R. Ruehle Chrissann
Published: March 2021

The Artificial Intelligence (AI) industry has experienced tremendous growth in recent years. Consequently, there has been considerable hype, interest, and even misinformation in the media regarding this emergent technology. Practitioners and academics alike are interested in learning how this market functions in order to make evidence-based decisions regarding its adoption. The purpose of this manuscript is to perform a systematic examination of the current market dynamics as well as identify future growth opportunities for the benefit of incumbents in addition to firms seeking to enter the AI market. The primary research question is: how do market and governmental forces reportedly shape AI adoptions? Drawing on predominantly practitioner focused literature, along with several seminal academic sources, the article begins by examining and mapping stakeholders in the market. This approach allows for the identification and analysis of key stakeholders. Semiconductor and cloud computing firms play a substantive role in the AI adoption ecosystem as they wield substantial power as revealed in this analysis. Subsequently, the TOE framework, which includes the technology, organization and environmental contexts, is applied in order to understand the role of these forces in shaping the AI market. This analysis demonstrates that large firms have a significant competitive advantage due to their extensive data collection and management capabilities in addition to attracting data scientists and high performing analytics professionals. Large firms are actively acquiring small and medium sized AI businesses in order to expand their offerings, particularly in dynamic emerging fields such as facial recognition technology and deep learning.
What Impact Does Cultural Integration Have on Strategic Acquisitions?
Authors: Cintron Ruben
Published: March 2021

Strategic acquisitions continue to emerge as a critical business strategy to expand an organization’s sales, customer bases, and growth opportunities. However, research and anecdotal evidence highlights that many of the strategic acquisitions fail to achieve their stated financial and non-financial goals (Mirvis & Marks, 2011). Many theories constructed to explain this phenomenon. However, there are still no clear explanations for the high failure rate (Stahl & Voigt, 2008). Post-merger activities consist of many moving parts, and researchers have cited cultural integration as an area of impacting the success or failure of an acquisition.
EVALUATION OF HYDROPONIC FODDER PERFORMANCE OF DIFFERENT VARIETIES OF SORGHUM
Authors: Gurmessa Kassahun , Garuma Zelalem
Published: March 2021

The hydroponic fodder yield performance evaluation of different varities of sorghum was conducted in green house of Wollega University.. Three experiments were conducted. The first was to observe effects of irrigation frequency. The second one was undertaken to evaluate four sorghum varieties (Lalo, Chemeda, Gamadi and Dano) on fodder yield, yield related components and nutritive values. The third experiment was done to determine the appropriate date of harvest for biomass yield and agronomic traits. Complete randomized design (CRD) was employed to conduct the experiment with three replications. The results showed that there was no significant difference (p>0.05) between treatments on   Dry matter yield (t/ha), Leaf Weight (t/ha), Root weight (t/ha) and Plant height (cm) as effect of frequency of watering at 2hr, 3hr and 4hr interval but, significant difference (p<0.05) among varieties of sorghums as an effect of frequency of irrigation on Fresh yield(t/ha), Plant height (cm) and leaf to root ratio (LRR%).The lowest average fresh yields were harvested at 7th days after planting and consistently increased until 17th days of planting. The highest plant heights were observed at 17 days while the lowest was observed at 7th days of harvesting. Except for dry matter (DM), Ash and crude protein (CP), there were significant differences (P<0.05) in neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and in vitro dry matter digestibility contents of the sorghum varieties. The Sorghum variety, Gamadi contained the highest CP (13.29%) and lowest Acid detergent lignin contents. The Sorghum variety, Chemeda showed best in vitro DM digestibility (73.24%). Harvesting hydroponic sorghum at 17 days after planting gave the best biomass yield (t/ha), LRR and Plant height (cm); showing the increase in biomass as time of harvesting increases. Among the tested varieties of sorghum a variety, Dano best for biomass yield among the others.
