description: Information systems development is driven by a variety of stakeholders – each with specific requirements. Modern agile development methods, like Scrum, allocate the vital step of prioritizing requirements to dedicated roles like the product owner. However, this can create a bottleneck and may lead to misunderstandings and conflicts between stakeholders. Enabling stakeholders to cooperatively prioritize requirements frees up product owners while involving stakeholders more closely in a crucial development step, strengthening their ties to the final system. Therefore, stakeholders must form a mutual and shared understanding of requirements. This research in progress utilizes the design science research methodology to propose design principles for a cooperative requirements prioritization system using the MuSCoW method – which classifies requirements in four categories. By transferring the theory of shared understanding to the field of requirements prioritization, we derive design principles for cooperative requirements prioritization systems. We enable a group of heterogeneous stakeholders to identify and discuss differences and come to a mutually-agreed prioritization decision. We introduce design features that instantiate these principles and present promising results of an initial pre-test. This research in progress contribute to information systems development by introducing principles for the under-researched, but important class of requirements prioritization systems.

description: Generalized form factors of hadrons are objects appearing in moments of the generalized parton distributions. Their leading-order DGLAP-ERBL QCD evolution is exceedingly simple and the solution is given in terms of matrix triangular structures of linear equations where the coefficients are the evolution ratios. We point out that this solution has a practical importance in analyses where the generalized form factors are basic objects, e.g., the lattice-gauge studies or models. It also displays general features of their evolution.

description: The phenomenon described as "information criminality" has taken significant proportions in the last decade, fact that carried out towards an international legislative frame, by implementing judicial forms, which might stop its occurrences. As matter of fact, the information criminality represents an information technology aiming towards fraud and prejudicing the users of informational data, by various means to infringement of the law. In this way, some international organizations have dealt with performing a legislative framework, able to punish the phenomenon of information criminality and implicitly to protect the users of computers. The transnational expansions, extremely fast as concerns the computer networks, and extending the access to these networks, by means of mobile telephony, have brought the increasing of these systems' vulnerability and the creating of opportunities of breaking the law. Considering these aspects, the world legislation is continuously changing, due to a more and more accelerated development of the information technology.
Un'indagine sull 'opera letteraria di Scipio Slataper
Creators: name: Aurelio, Vittorio Monti
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to follow the artistic development of Scipio Slataper, a young Italian writer at the dawn of the twentieth century and to discuss his literary achievements from the early writings to the works that mark the peak of his literary career. In chapter one, the activities of Slataper with "La Voce", one of the leading literary journals; of the period, will be discussed. The cultural personalities involved in this journal were responsible for major changes brought about in modern Italian literature. Chapter two will be devoted to Slataper's correspondence with three young ladies of the period. The collection of these letters, destined to become a book, constitutes and interesting document of the intimate life of the artist, his loves, fear, frustration and triumph over disillusionment. The third chapter will focus on the later relationship Slataper had with the writers who contributed to "La Voce" and will show the increasing friction and final rupture of this group. The fourth chapter will deal with "II mio Carso", one of the major works of Slataper and an original contribution to the development of the narrative forms in modern Italian literature. The fifth chapter will offer an evaluation of Slataper's career as a writer and critic which culminates in his major work: "Ibsen". Slataper's essay views the life of the Norwegian dramatist, not through the sharp instruments of the critic, but rather through the sensitivity of another artist.

description: In recent years, technical and theoretical work to detect moons and rings around exoplanets has been attempted. The small mass/size ratios between moons and planets means this is very challenging, having only one exoplanetary system where spotting an exomoon might be feasible (i.e. Kepler-1625b i). In this work, we study the dynamical evolution of ringed exomoons, dubbed "cronomoons" after their similarity with Cronus (Greek for Saturn), and after Chronos (the epitome of time), following the Transit Timing Variations (TTV) and Transit Duration Variation (TDV) that they produce on their host planet. Cronomoons have extended systems of rings that make them appear bigger than they actually are when transiting in front of their host star. We explore different possible scenarios that could lead to the formation of such circumsatellital rings, and through the study of the dynamical/thermodynamic stability and lifespan of their dust and ice ring particles, we found that an isolated cronomoon can survive for time-scales long enough to be detected and followed up. If these objects exist, cronomoons' rings will exhibit gaps similar to Saturn's Cassini Division and analogous to the asteroid belt's Kirkwood gaps, but instead raised due to resonances induced by the host planet. Finally, we analyse the case of Kepler-1625b i under the scope of this work, finding that the controversial giant moon could instead be an Earth-mass cronomoon. From a theoretical perspective, this scenario can contribute to a better interpretation of the underlying phenomenology in current and future observations.

description: Random Number Generators play a critical role in a number of important applications. In practice, statistical testing is employed to gather evidence that a generator indeed produces numbers that appear to be random. In this paper, we reports on the studies that were conducted on the compressed data using 8 compression algorithms or compressors. The test results suggest that the output of compression algorithms or compressors has bad randomness, the compression algorithms or compressors are not suitable as random number generator. We also found that, for the same compression algorithm, there exists positive correlation relationship between compression ratio and randomness, increasing the compression ratio increases randomness of compressed data. As time permits, additional randomness testing efforts will be conducted.

description: Temporal information is crucial for detecting occluded instances. Existing temporal representations have progressed from BEV or PV features to more compact query features. Compared to these aforementioned features, predictions offer the highest level of abstraction, providing explicit information. In the context of online vectorized HD map construction, this unique characteristic of predictions is potentially advantageous for long-term temporal modeling and the integration of map priors. This paper introduces PrevPredMap, a pioneering temporal modeling framework that leverages previous predictions for constructing online vectorized HD maps. We have meticulously crafted two essential modules for PrevPredMap: the previous-predictions-based query generator and the dynamic-position-query decoder. Specifically, the previous-predictions-based query generator is designed to separately encode different types of information from previous predictions, which are then effectively utilized by the dynamic-position-query decoder to generate current predictions. Furthermore, we have developed a dual-mode strategy to ensure PrevPredMap's robust performance across both single-frame and temporal modes. Extensive experiments demonstrate that PrevPredMap achieves state-of-the-art performance on the nuScenes and Argoverse2 datasets. Code will be available at https://github.com/pnnnnnnn/PrevPredMap.

description: Logistic regression is a standard procedure for real-world classification problems. The challenge of class imbalance arises in two-class classification problems when the minority class is observed much less than the majority class. This characteristic is endemic in many domains. Work by Owen [2007] has shown that cluster structure among the minority class may be a specific problem in highly imbalanced logistic regression. In this paper, we propose a novel relabeling approach to handle the class imbalance problem when using logistic regression, which essentially assigns new labels to the minority class observations. An Expectation-Maximization algorithm is formalized to serve as a tool for efficiently computing this relabeling. Modeling on such relabeled data can lead to improved predictive performance. We demonstrate the effectiveness of this approach with detailed experiments on real data sets.
Guided run-and-tumble active particles: wall accumulation and preferential deposition

description: Bacterial biofilms cost an enormous amount of resources in the health, medical, and industrial sectors. To understand early biofilm formation, beginning from planktonic states of active bacterial suspensions (such as Escherichia coli) to microcolonization, it is vital to study the mechanics of accumulation near surfaces and subsequent deposition. In this study, analytical expressions for the mean orientation, density and angular distributions, and deposition rates in such bacterial suspensions are derived, with and without the effects of external guiding or taxis fields. Simulations of confined active particles, using the run-and-tumble statistics from well-established three-dimensional tracking experiments and a preferential sticking probability model for deposition, closely verify the derived mean orientation, density profiles, angular distributions, and deposition rates. It is found that the size distribution of deposited microcolonies remains unaffected when guiding fields are applied, however, the pair correlation function of deposited structures relatively spreads out. The factor behind the changes in the accumulation patterns, and the changes in the architecture of deposited biomass, turns out to be an asymmetrical rotational drift caused by the guiding fields, and is an important physical mechanism behind the organization in confined active particle suspensions.

description: Continual learning (CL) learns a sequence of tasks incrementally with the goal of achieving two main objectives: overcoming catastrophic forgetting (CF) and encouraging knowledge transfer (KT) across tasks. However, most existing techniques focus only on overcoming CF and have no mechanism to encourage KT, and thus do not do well in KT. Although several papers have tried to deal with both CF and KT, our experiments show that they suffer from serious CF when the tasks do not have much shared knowledge. Another observation is that most current CL methods do not use pre-trained models, but it has been shown that such models can significantly improve the end task performance. For example, in natural language processing, fine-tuning a BERT-like pre-trained language model is one of the most effective approaches. However, for CL, this approach suffers from serious CF. An interesting question is how to make the best use of pre-trained models for CL. This paper proposes a novel model called CTR to solve these problems. Our experimental results demonstrate the effectiveness of CTR

description: This study reports the spontaneous linguistic behaviour of three children acquiring French as a first language. The introductory chapter presents such information as the children's ages and the parents' linguistic background. In Chapter Two, the children's abilities to pose questions, make requests, and give commands are described. Chapter Three discusses the various negative speech actions that the children are able to perform, and the scope or range of each child's negation vocabulary. Chapter Four discusses the children's abilities to initiate, participate, and recognize linguistic play, that is, speech which is in direct contradiction with the facts and is not intended to be serious. Finally, the concluding chapter summarizes the study and points out its significant findings.

description: This paper studies continual learning (CL) of a sequence of aspect sentiment classification(ASC) tasks in a particular CL setting called domain incremental learning (DIL). Each task is from a different domain or product. The DIL setting is particularly suited to ASC because in testing the system needs not know the task/domain to which the test data belongs. To our knowledge, this setting has not been studied before for ASC. This paper proposes a novel model called CLASSIC. The key novelty is a contrastive continual learning method that enables both knowledge transfer across tasks and knowledge distillation from old tasks to the new task, which eliminates the need for task ids in testing. Experimental results show the high effectiveness of CLASSIC.

description: NH$_{3}$(ammonia) plays a critical role in the chemistry of star and planet formation, yet uncertainties in its binding energy (BE) values complicate accurate estimates of its abundances. Recent research suggests a multi-binding energy approach, challenging the previous single-value notion. In this work, we use different values of NH$_{3}$ binding energy to examine its effects on the NH$_{3}$ abundances and, consequently, in the early evolution of protostellar cores. Using a gas-grain chemical network, we systematically vary the values of NH$_{3}$ binding energies in a model Class 0 protostellar core and study the effects of these binding energies on the NH$_{3}$ abundances. Our simulations indicate that abundance profiles of NH$_{3}$ are highly sensitive to the binding energy used, particularly in the warmer inner regions of the core. Higher binding energies lead to lower gas-phase NH$_{3}$ abundances, while lower values of binding energy have the opposite effect. Furthermore, this BE-dependent abundance variation of NH$_{3}$ significantly affects the formation pathways and abundances of key species such as HNC, HCN, and CN. Our tests also reveal that the size variation of the emitting region due to binding energy becomes discernible only with beam sizes of 10 arcsec or less. These findings underscore the importance of considering a range of binding energies in astrochemical models and highlight the need for higher resolution observations to better understand the subtleties of molecular cloud chemistry and star formation processes.

description: We investigate ground state properties of a quasi-one-dimensional electron-lattice coupled model for quarter-filled molecular conductors. The effective one-dimensional extended Hubbard model coupled to adiabatic lattice degree of freedom is derived by the inter-chain mean-field approximation and solved by Lanczos exact diagonalization method. We find that the critical behavior among lattice tetramerized states with different charge-lattice ordered patterns is sensitively affected by the inter-chain Coulomb interaction, lattice anharmonicity, and intrinsic dimerization. This indicates a subtle balance between these states originating from strong correlation and reduced dimensionality.

description: The structural and electrical characterizations of mechanically-milled (MM) amorphous fast ionic conductors (a-FICs), viz. xAgI (100-x)[0.67 Ag\_2 O-0.33V\_2O\_5] (x = 40, 50, 55 and 70) have been reported. The amorphisation is restricted only to the compositions which are well within the glass forming region and all samples are found to be highly agglomerated and X-ray amorphous in nature. The frequency dependent ac conductivity, σ'(ω), of the amorphous samples investigated in the frequency range 5Hz -13 MHz and temperature range 100- 350 K shows a dc conductivity regime at low frequencies and a dispersive regime at higher frequencies. The spectra can be described by the Jonscher power law (JPL), \simga'(ω) = σ\_dc +A(T) ω\_n. However, the values σ\_dc (T) and A(T) both show two distinct Arrhenius regions and n (< 1) is found to be temperature dependent, i.e., decreasing with increasing temperature.

description: Recent studies have revealed that the interlayer interaction in two-dimensional (2D) layered materials is not simply of van der Waals character but could coexist with quasi-bonding character. Here we classify the interlayer quasi-bonding interactions into two main categories (I: homo-occupancy interaction, II: hetero-occupancy interaction) according to the occupancy of the involved energy bands near the Fermi level. Then we investigate the quasi-bonding-interaction-induced band structure evolution of several representative 2D materials based on density functional theory calculations. Further calculations confirm that this classification is applicable to generic 2D layered materials and provides a unified understanding of the total strength of interlayer interaction, which is a synergetic effect of the van der Waals attraction and the quasi-bonding interaction. The latter is stabilizing in main category II and destabilizing in main category I. Thus, the total interlayer interaction strength is relatively stronger in category II and weaker in category I.

description: The recently measured experimental data of Legnaro National Laboratories on neutron rich even isotopes of $^{62-66}$Fe with A=62,64,66 have been interpreted in the framework of large scale shell model. Calculations have been performed with a newly derived effective interaction GXPF1A in full $\it{fp}$ space without truncation. The experimental data is very well explained for $^{62}$Fe, satisfactorily reproduced for $^{64}$Fe and poorly fitted for $^{66}$Fe. The increasing collectivity reflected in experimental data when approaching N=40 is not reproduced in calculated values. This indicates that whereas the considered valence space is adequate for $^{62}$Fe, inclusion of higher orbits from $\it{sdg}$ shell is required for describing $^{66}$Fe.

description: THz amplitude modulators and switches are considered to be the main building blocks of future THz communication systems. Despite rapid progress, modulation and switching devices in this electromagnetic spectrum lag far behind other frequency ranges. Currently, THz modu-lators face major challenges in consistently producing high modulations depths over large frequency bands. Moreover, a convenient integration for practical applications requires that the modulation/switching properties can be electrically controlled. Devices fulfilling all these con-ditions remain to be demonstrated. In this work we show that W-doped VO2 films grown by direct-current magnetron sputtering can be efficiently used for the development reliable, large-area, broadband THz waves modulators. We demonstrate that W doping not only permits to tune the insulator to metal transition (IMT) temperature of VO2, but also, most importantly, to control the topology of the electrically activated transition. In situ / operando X-ray diffraction and Raman spectroscopy characterizations of the devices, coupled with standard resistivi-ty measurements and time-domain THz spectroscopy, unambiguously demonstrate that the changes in the spatial distribution of the IMT is due to structural distortions induced by W doping.

description: An algorithm is presented for approximating arbitrary powers of a black box unitary operation, $\mathcal{U}^t$, where $t$ is a real number, and $\mathcal{U}$ is a black box implementing an unknown unitary. The complexity of this algorithm is calculated in terms of the number of calls to the black box, the errors in the approximation, and a certain `gap' parameter. For general $\mathcal{U}$ and large $t$, one should apply $\mathcal{U}$ a total of $\lfloor t \rfloor$ times followed by our procedure for approximating the fractional power $\mathcal{U}^{t-\lfloor t \rfloor}$. An example is also given where for large integers $t$ this method is more efficient than direct application of $t$ copies of $\mathcal{U}$. Further applications and related algorithms are also discussed.

description: With the help of Stokes operator S2 squeezed state (also called polarization squeezed state (PSS)) of 795-nm light, rubidium-87 (87Rb) atomic magnetometer based on Faraday rotation has been implemented and characterized.The PSS of Stokes operator S2 of 795-nm light has been prepared by means of coherently combining the polarization coherent state (PCS) of a linearly p-polarized bright 795-nm light beam and a linearly s-polarized squeezed vacuum state (SVS) generated by a 397.5-nm ultraviolet laser pumped sub-threshold optical parametric oscillator (OPO) with a PPKTP bulk crystal inside the OPO cavity.PSS with a squeezing level of -3.7 has been achieved around the analysis frequency of 10 kHz. At different transitions of D1 line, various frequency detuning, and reasonable atomic vapor cells temperature, Faraday rotation has been measured and compared.To decrease absorption (scattering) losses and the back-action from atomic spin noise to the probe beams polarization noise for maintaining the quantum properties of PSS of Stokes operator S2 of 795-nm light, we had to run our magnetometer with 87Rb vapor cells temperature below 60, at which the PSS was almost destroyed.The sensitivities of magnetic field measurement were characterized via measuring signal-to-noise ratio of the alternating current (AC) calibrated magnetic field signal with a balanced polarimeter. Under the conditions of the atomic number density of 5.8*1010 /cm3 and the probe beam with a detuning of - 400 MHz relative to the 5S1/2 (Fg=2) - 5P1/2 (Fe=1) transition of 87Rb D1 line, a typical sensitivity of 19.5 pT/Hz1/2 has been achieved employing PSS of Stokes operator S2 as the probe, compared with a sensitivity of 28.3 pT/Hz1/2 using PCS as the probe.We preliminarily demonstrated that the quantum-enhanced sensitivity in a Faraday-rotation-based 87Rb atomic magnetometer with the help of PSS of 795-nm light.

description: Entanglement is one of the most prominent features of quantum mechanics and serves as an essential resource in quantum information science. Therefore, the certification of entanglement is crucial for quantum information processing tasks. While entanglement witnesses are the most frequently used method for entanglement certification in experiments, recent research shows that even tiny errors in measurements may significantly undermine the effectiveness of a witness. In this work, we propose a randomized-measurement-based method to solve this problem. Through this method, the errors in measurement results can be substantially suppressed, thereby restoring the certification capability of entanglement witnesses. Our method is not only applicable to general types of witnesses, including multi-party entanglement and high-dimensional entanglement witnesses, but also experimentally friendly in the sense that only slight modifications are needed to the original measurement settings.

description: The mass and effective density of black carbon (BC) particles generated from aque-ous suspensions of Aquadag and fullerene soot was measured and parametrized asa function of their mobility diameter. The measurements were made by two indepen-dent research groups by operating a differential mobility analyser (DMA) in series with an aerosol particle mass analyser (APM) or a Couette centrifugal particle mass anal-yser (CPMA). Consistent and reproducible results were found in this study for differentproduction lots of Aquadag, indicating that the effective density of these particles isa stable quantity and largely unaffected by differences in aerosol generation proce-dures and suspension treatments. The effective density of fullerene soot particles from one production lot was also found to be stable and independent of suspension treat-ments. Some difference to previous literature data was observed for both Aquadagand fullerene soot at larger particle diameters. Knowledge of the exact relationshipbetween mobility diameter and particle mass is of great importance, as DMAs arecommonly used to size-select particles from BC reference materials for calibration of single particle soot photometers (SP2), which quantitatively detect the BC mass insingle particles.

title: Behind the Silk Screen a Critical Analysis of Translators, (In)visibilty, and Alternative Translation Environments
Creators: name: Sprague, Justin Charles

description: The act of translation is one that is riddled with difficulties, and the labor that the translator performs is equally as difficult. Translators must simultaneously grapple with linguistic issues from languages being incongruent as well as the aspects of language embedded with culture. These complexities have given rise to the study of translation and the struggles that translators face. What often goes unnoticed, however, are the ways in which the habitus of translators informs their cultural labor. Likewise, their position as cultural intermediaries between a target and source culture illuminate challenges that are not explicitly answered or even addressed in traditional translation theory.

This thesis examines the way that translators are situated within institutional contexts and the subsequent effects that has on their labor. By positioning them in the middle of the various intersections that complicate the process of translation, I argue that it is possible to discern ways that translators may ameliorate issues of invisibility and more efficiently address concerns over culture, gender, and post-colonialism. I locate this discussion in a Korean context, including an analysis of the overlap of Korean studies with translation studies. Likewise, a discussion of two Korean memoirs translated into English addresses issues of function and habitus. Lastly, an analysis of a digital fansubbing community challenges the traditional habitus of translators and reimagines the ways in which their labor is performed.

Description of peasantry in the main works of Russian prose literature from the mid-nineteenth century to 1917
Creators: name: Rosovsky, Sophia
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this paper is to observe and discuss the description of peasantry in Russian prose literature from the second half of 1840's to 1917. In the introduction is given an outline of the peasant theme before the forties. For that purpose all material is sub-divided into chapters; each chapter discusses an individual writer, except the fourth chapter which considers the raznochintzy writers. The initial chapter discusses the first works of Grigorovich which are concerned with peasant life in the forties. Chapter Two deals with Turgenev's stories from A Sportsman's Sketches which show the spiritual and poetical side of the peasantry. The Third chapter discusses the works of Pisemsky of the fifties; here the realistic description of peasantry reaches its height. Chapter Four is a detailed analysis of the works of the raznochintzy writers of the sixties and seventies: Sleptzov, Levitov, Reshetnikov and mainly Gleb Uspensky. They are compared with their predecessors as well as compared among themselves. Chapter Five discusses the main works of Korolenko who acquaints the reader with the way of life of the Yakuts, Tartars, the Siberian and Russian peasants, and nomads. The Sixth chapter deals with the main works of Chekhov concerned with the peasantry. His works retain in themselves the sober truth of both the portrayal of the raznochintzy writers of the sixties and the artistic beauty of Turgenev. The Seventh chapter considers the works of Bunin where they are compared with those of Chekhov. With Bunin's works ends the period of critical realism before 1917. This is followed by a short conclusion, where some works of Tolstoy are discussed.

description: As the Internet help us cross cultural border by providing different information, plagiarism issue is bound to arise. As a result, plagiarism detection becomes more demanding in overcoming this issue. Different plagiarism detection tools have been developed based on various detection techniques. Nowadays, fingerprint matching technique plays an important role in those detection tools. However, in handling some large content articles, there are some weaknesses in fingerprint matching technique especially in space and time consumption issue. In this paper, we propose a new approach to detect plagiarism which integrates the use of fingerprint matching technique with four key features to assist in the detection process. These proposed features are capable to choose the main point or key sentence in the articles to be compared. Those selected sentence will be undergo the fingerprint matching process in order to detect the similarity between the sentences. Hence, time and space usage for the comparison process is reduced without affecting the effectiveness of the plagiarism detection.

description: Audio-driven one-shot talking face generation methods are usually trained on video resources of various persons. However, their created videos often suffer unnatural mouth shapes and asynchronous lips because those methods struggle to learn a consistent speech style from different speakers. We observe that it would be much easier to learn a consistent speech style from a specific speaker, which leads to authentic mouth movements. Hence, we propose a novel one-shot talking face generation framework by exploring consistent correlations between audio and visual motions from a specific speaker and then transferring audio-driven motion fields to a reference image. Specifically, we develop an Audio-Visual Correlation Transformer (AVCT) that aims to infer talking motions represented by keypoint based dense motion fields from an input audio. In particular, considering audio may come from different identities in deployment, we incorporate phonemes to represent audio signals. In this manner, our AVCT can inherently generalize to audio spoken by other identities. Moreover, as face keypoints are used to represent speakers, AVCT is agnostic against appearances of the training speaker, and thus allows us to manipulate face images of different identities readily. Considering different face shapes lead to different motions, a motion field transfer module is exploited to reduce the audio-driven dense motion field gap between the training identity and the one-shot reference. Once we obtained the dense motion field of the reference image, we employ an image renderer to generate its talking face videos from an audio clip. Thanks to our learned consistent speaking style, our method generates authentic mouth shapes and vivid movements. Extensive experiments demonstrate that our synthesized videos outperform the state-of-the-art in terms of visual quality and lip-sync.

description: We constrain the primordial non-Gaussianity parameter of the local model f_{NL} using the skewness power spectrum associated with the two-to-one cumulant correlator of cosmic microwave background temperature anisotropies. This bispectrum-related power spectrum was constructed after weighting the temperature map with the appropriate window functions to form an estimator that probes the multipolar dependence of the underlying bispectrum associated with the primordial non-Gaussianity. We also estimate a separate skewness power spectrum sensitive more strongly to unresolved point sources. When compared to previous attempts at measuring the primordial non-Gaussianity with WMAP data, our estimators have the main advantage that we do not collapse information to a single number. When model fitting the two-to-one skewness power spectrum we make use of bispectra generated by the primordial non-Gaussianity, radio point sources, and lensing-secondary correlation. We analyze Q, V and W-band WMAP 5-year data using the KQ75 mask out to l_{max}=600. Using V and W-band data and marginalizing over model parameters related to point sources and lensing-secondary bispectrum, our overall and preferred constraint on f_{NL} is 11.0\pm23.7 at the 68% confidence level (-36.4 < f_{NL} < 58.4 at 95% confidence). We find no evidence for a non-zero value of f_{NL} even marginally at the 1σlevel.

description: The ICT sector, responsible for 2% of global carbon emissions, is under scrutiny calling for methodologies and tools to design and develop software in an environmentally sustainable-by-design manner. However, the software engineering solutions for designing and developing carbon-efficient software are currently scattered over multiple different pieces of literature, which makes it difficult to consult the body of knowledge on the topic. In this article, we precisely conduct a systematic literature review on state-of-the-art proposals for designing and developing carbon-efficient software. We identify and analyse 65 primary studies by classifying them through a taxonomy aimed at answering the 5W1H questions of carbon-efficient software design and development. We first provide a reasoned overview and discussion of the existing guidelines, reference models, measurement solutions and techniques for measuring, reducing, or minimising the carbon footprint of software. Ultimately, we identify open challenges and research gaps, offering insights for future work in this field.
