description: Product development (PD) includes many activities that must be performed by professionals from different areas, with a pluralist and complimentary perspective. The existing literature presents an important subject that is poorly explored: the points of contact, that is, activities that require cross-functional integration to be carried out. Thus, the purpose of this study is to characterize the crossfunctional integration in the points of contact points of seed development processes, in the agricultural industry. We interviewed 10 employees representing different stages of the PD process, of two multinational seed companies. Based on this it was possible to obtain opinions on the characteristics of the stages: initial, intermediate and final. Through the interpretation of the results, it was possible to create a framework with the following dimensions: cross-functional integration, PD phases, and PD objectives. Depending on the area where the employee works, he/she participated only in a particular phase, decreasing his/her knowledge of the subsequent phases and vice versa. Thus, they do not have a multidimensional view of the PD process, which can be a source of conflicts in the PD process as a whole. There are also cases where, within a given phase, there is a high integration level between functions, however, when the process reaches the next phase, there is a low integration level between the functions of previous and subsequent stages.

description: (Abridged) Projected rotational velocities (vsini) have been measured for a sample of 145 stars with masses between 0.4 and >10 Msun (median mass 2.1 Msun) located in the Orion star-forming complex. These measurements have been supplemented with data from the literature for Orion stars with masses as low as 0.1 Msun. The primary finding from analysis of these data is that the upper envelope of the observed values of angular momentum per unit mass (J/M) varies as M^0.25 for stars on convective tracks having masses in the range ~0.1 to ~3 Msun. This power law extends smoothly into the domain of more massive stars (3 to 10 Msun), which in Orion are already on the ZAMS. This result stands in sharp contrast to the properties of main sequence stars, which show a break in the power law and a sharp decline in J/M with decreasing mass for stars with M <2 Msun. A second result of our study is that this break is seen already among the PMS stars in our Orion sample that are on radiative tracks, even though these stars are only a few million years old. A comparison of rotation rates seen for stars on either side of the convective-radiative boundary shows that stars do not rotate as solid bodies during the transition from convective to radiative tracks.

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We analyze 16 failed filament eruptions observed near 24 solar cycle maximum from May 2013 to July 2014. No significant rotation of filament spines is observed during the ascent in all studied failed eruptions, which does not support kink-instability mechanism of triggering the eruptions. We calculate potential magnetic field distributions in the corona above the initial locations of the filaments to study their height dependence. In seven events, the vertical profiles of the decay index $n$ are monotonic. The other nine events occur in the regions with the switchback or saddle-like n-profiles. The direction of the horizontal field near the saddle bottom is turned through more than 100$^\circ$ relative its direction at the initial filament position, which reveals the quadrupolar magnetic configuration with null points in these regions. The eruptive filaments stop above the null points where the total Lorenz force is directed upward. The most reasonable force that can terminate filament ascending and balance the Lorenz force seems the gravity.

description: This research aims to demonstrate how economic and social impacts may be evidenced by the Statement of Added Value (SAV). To accomplish the objective of the research, a model of Statement Added Value was made and then an empirical research was done by means of a case study. The main changes suggested to the SAV current model were the separation of the cooperative act and the noncooperative act regarding information based on revenues and inputs, and the disclosure of the price differential paid to information acquired from the input member, one of the returns offered by cooperatives omitted in current accounting. Furthermore, this work suggests the inclusion of items related to the remuneration of director and employee educational assistance, insertion of information on fines and offenses committed by the cooperative, inclusion of socio-economic contributions made by the cooperative associates and technical and educational assistance items provided to members. The completion of the case study attested to the possibility of preparing the SAV proposal for agricultural cooperatives based on available financial information, as well as quantifying the socioeconomic impact in the region in which the agricultural cooperatives are inserted, demonstrating benefits to cooperative, society and government agencies.

description: The UBC Food System Project is in its third year and aims to assess and improve the sustainability of the UBC Food System. Building on the best of the general models prepared for this purpose in 2003, we examine the sustainability of one specific part of the UBC Food System, namely Agora, the student-run food outlet in the Faculty of Agricultural Science’s MacMillan Building. We select a total of four indicators to represent and measure economic, social and ecological sustainability, and we assess Agora’s current business model against these indicators. While we find that Agora does well with respect to ecological sustainability, we find significant room for improvement in economic and social sustainability. Several recommendations are made with respect to each indicator, and instruments are provided for measuring and assessing progress over time.

description: The impact of sugarcane production versus the production of other foods has been globally discussed, with emphasis on the fairness of land use in supplying these products - food and fuel. This approach also interferes in the composition of land structure that houses the products offered and demanded by individuals. In this sense, the objective of this research was to analyze whether the change in land use – from food to biofuels - affects food security. To achieve the proposed objective, the Shift-Share model, , which examines the cultures that have the ability to replace certain crops, was used. Subsequently, the Spearman correlation was used to investigate the relations between cultures. Specialization indicators and a time series analysis for formatting the number of establishments and their areas, we also used to monitor the evolution of land ownership. The results showed that, although the expansion of cultivation of sugarcane in the state of MatoGrosso do Sul has affected the food production areas, it does not compromise food safety.

description: This article aims at analyzing the exportation agenda of the soybean complex and its changes with the advent of the Kandir Law and the participation of China, under the hypothesis that these events can generate negative externalities for Brazilian economy in terms of reprimarization of the country’s exportation agenda. For this, we analyzed the production and trade data of the soybean complex in Brazil and in the world, and researched the factors that influence the commercialization of these products. As a result, there was a decrease in the exports of products with higher added value, such as oil and bran, and a significant increase in the export of in natura soybean. The Kandir Law, China’s trade profile and the use of tariff scale practices contributed for such an occurrence.

description: This is Part II of a four-part opinion review on traditional neuropsychological assessment methods and findings associated with mild traumatic brain injury (mTBI). This Part II review focuses on historical, psychometric and statistical issues involving traditional neuropsychological methods that have been used in neuropsychological outcome studies of mTBI, but demonstrates the critical limitations of traditional methods. This is an opinion review. Traditional neuropsychological tests are dated and lack specificity in evaluating such a heterogenous and complex injury as occurs with mTBI. In this review, we demonstrate traditional neuropsychological methods were never developed as standalone measures for detecting subtle changes in neurocognitive or neurobehavioral functioning and likewise, never designed to address the multifaceted issues related to underlying mTBI neuropathology symptom burden from having sustained a concussive brain injury. For neuropsychological assessment to continue to contribute to clinical practice and outcome literature involving mTBI, major innovative changes are needed that will likely require technological advances of novel assessment techniques more specifically directed to evaluating the mTBI patient. These will be discussed in Part IV.

description: Oxide heterojunctions made of p-type L0.8Sr0.2MnO3 (LSMO) and niobium-doped n-type SrTiO3 (STO:Nb) have been fabricated by the pulsed laser deposition (PLD) technique and are characterized under UV light irradiation by measuring the current-voltage, photovoltaic properties and the junction capacitance. It is shown that the heterojunctions work as an efficient UV photodiode, in which photogenerated holes in the STO:Nb substrate are injected to the LSMO film. The maximum surface hole density Q/e and external quantum efficiency gamma are estimated to be 8.3x1012 cm-2 and 11 % at room temperature, respectively. They are improved significantly in a p-i-n junction of LSMO/STO/STO:Nb, where Q/e and gamma are 3.0x1013 cm-2 and 27 %, respectively.

description: This study aimed to analyze the economic viability of tilapia farming (Oreochromis niloticus) using a small-scale recirculating water system in the municipality of Parnaiba-PI, Brazil. We verified the marketing data regarding the economic viability of two production cycles, using three 2.5 x 5.7 x 0.7 meter tankss, with a final weight of 500 grams. With the data obtained, the annual production of 660 kg after two cycles of fattening of 165 days were estimated. Indicators such as gross revenue, operating income, gross margin, profitability index, leveling point, net present value, benefit cost ratio, payback, internal rate of return and sensitivity analysis were analyzed. The implementation cost was of R$ 9,370.94. Given that the return investment will occur in the sixth month of the fifth year, the Net Present Value (NPV) is of R$ 2.759.55, the leveling point is of 38.20% and the Internal Rate of Return (IRR) will be of 19.40%. With this, the project can be considered economically viable, provided it is not the only source of family income, since it is able to generate a monthly income equivalent to R$ 226.91.

description: This article discusses the theme of sustainability from the point-of-view of Agroindustrial Systems (AGSs). For this, we used an analysis model for sustainable AGSs. The New Institutional Economy, specifically the Transition Costs Economy, is the theoretical framework of the research. Presuppositions and hypothesis are evaluated by means of a multicase study on the sustainability of the transaction between the producer and the industry within the AGS of beef from Mato Grosso do Sul, Brazil. Cases relevant to the theme were chosen: Mato Grosso do Sul Association of the producers of precocious calf, Good agricultural practices program – EMBRAPA cattle, and Brazilian Association of Organic Livestock. In short, the analyses of the cases allowed for the characterization of these AGSs and the identification of risks associated to capturing the value generated by the investment in specific assets dedicated to sustainability. Furthermore, we suggest a set of hypotheses to be tested and validated in future researches regarding the efficiency and stability of sustainable AGSs.

description: Leading companies of the industry sector demonstrate their competencies through performance. The biggest challenge of the nonleading companies is to understand the difference in the actions of the leading companies in order to maintain this position, that is, mimic them or develop new capabilities. This paper aimed at identifying which are the factors that make the companies reach and maintain competitive advantage in the biodiesel industry. For this, we applied an exploratory qualitative methodology in which five different data collection tools were used. We identified five factors related to the creation of competitive advantage in the biodiesel sector. These factors are: supply chain management focused on the anticipated or postponed purchase and on the diversification of raw-material; supply chain management focused on the reduction in the costs of inputs; cost and industrial yields management; ICMS tax pickups; and proximity of customers and differentiated logistics structures. After identifying the factors, six companies, recognized in the market by their industrial capacity usage and market share, were chosen. In all these companies, there was at least one of the factors that generates competitive advantage. This paper has academic and practical implications since it clearly delimitates the factors that are capable of leading companies toward a leadership position.

We adopted the historiographical review as analytical method, following the efforts of the movement for more history in Organizational Studies. Therefore, the landmarks pointed out in our review were evaluated from the prevailing conception of each season. In this sense, we reveal distinct conceptions of water: as an abunudat and inexhaustible reource, a strategic issue for industrialization, an exclusive resource in charge of Federal Administration, and a good with multiple use and interests.

description: In this paper, the holographic p-wave superfluid model with charged complex vector field is studied in dRGT massive gravity beyond the probe limit. The stability of p-wave and p+ip solutions are compared in the grand canonical ensemble. The p-wave solution always get lower value of grand potential than the p+ip solution, showing that the holographic system still favors an anisotropic (p-wave) solution even with considering a massive gravity theory in bulk. In the holographic superconductor models with dRGT massive gravity in bulk, a key sailing symmetry is found to be violated by fixing the reference metric parameter $c_0$. Therefore, in order to get the dependence of condensate and grand potential on temperature, different values of horizon radius should be considered in numerical work. With a special choice of model parameters, we further study the dependence of critical back-reaction strength on the graviton mass parameter, beyond which the superfluid phase transition become first order. We also give the dependence of critical temperature on the back reaction strength $b$ and graviton mass parameter $m^2$.

description: This paper seeks to investigate the official communicative activities among Nigerian paramilitary formations in Akwa Ibom State, with a view to determining the peculiar forms generated through morphological processes that occur in their interactions. The agencies selected for the study are: the Nigeria Police Force, the Federal Road Safety Corps and the Nigeria Security and Civil Defence Corps. The theoretical framework adopted for, and considered relevant to the study is Lieb’s Theory of Process Model of Word Formation. The theory offers a comprehensive approach which accounts for all processes of word formation in a unified way. Data used for the study were collected through participant observation and unstructured interview of personnel while on duty within the office environment using random sampling method. The findings indicate that the operatives used English language for their formal conversations to communicate paramilitary ideology. In addition, they were found to have used unique lexical choices created specifically to serve the communication needs of the interlocutors. It is therefore recommended that operatives of these agencies should ‘simplify’ their morphologically-conditioned terminologies in particular, and the language in general, such that the public which they are meant to serve could understand. Keywords: Paramilitary formations, English language, Communication needs, Words formation, Lexical choices.

description: To investigate the relationship between on-road driving remediation and achieving fitness to drive following acquired brain injury. Randomized controlled trial. Tertiary hospital outpatient driver assessment and rehabilitation service, Australia. Thirty-five participants (54.3% male), aged 18–65 years, 41 days-20 years post-acquired brain injury (including stroke, aneurysm, traumatic brain injury) recommended for on-road driving remediation following occupational therapy driver assessment were randomly assigned to intervention (n = 18) and waitlist control (n = 17) groups. Intervention group received on-road driving remediation delivered by a qualified driving instructor in a dual-control vehicle. The waitlist control group completed a 6 week period of no driving-related remediation. Fitness to drive rated following the conduct of an on-road occupational therapy driver assessment with a qualified driving instructor where outcome assessors were blinded to group allocation. The intervention group were significantly more likely to achieve a fit to drive recommendation than no driving specific intervention (p = 0.003). Following comprehensive assessment, individualized on-road driving remediation programs devised by an occupational therapist with advanced training in driver assessment and rehabilitation and delivered by a qualified driving instructor are significantly associated with achieving fitness to drive after acquired brain injury.

description: Manipulating the atomic and electronic structure of matter with strong terahertz (THz) fields while probing the response with ultrafast pulses at x-ray free electron lasers (FELs) has offered unique insights into a multitude of physical phenomena in solid state and atomic physics. Recent upgrades of x-ray FEL facilities are pushing to much higher repetition rates, enabling unprecedented signal to noise for pump probe experiments. This requires the development of suitable THz pump sources that are able to deliver intense pulses at compatible repetition rates. Here we present a high power laser-driven THz source based on optical rectification in LiNbO3 using tilted pulse front pumping. Our source is driven by a kilowatt-level Yb:YAG amplifier system operating at 100 kHz repetition rate and employing nonlinear spectral broadening and recompression to achieve sub-100 fs pulses at 1030 nm wavelength. We demonstrate a maximum of 144 mW average THz power (1.44 uJ pulse energy), consisting of single-cycle pulses centered at 0.6 THz with a peak electric field strength exceeding 150 kV/cm. These high field pulses open up a range of possibilities for nonlinear time-resolved experiments with x-ray probing at unprecedented rates.

Our framework uses a dual reputation model where consumers have a quality expectation based on the reputation of the platform and the reputation of the seller. We also analyze the benets and costs of various types of fees associated with online platforms. We nd that the optimal fee structure may depend upon weighing quality concerns with market power concerns. The optimal quality standard may also depend upon the fee structure, as well as the level of compliance to that standard.

description: The Brain Injury Guidelines (BIG) categorize the severity of Traumatic Brain Injury (TBI). The efficacy of BIG in predicting radiological deterioration and the necessity for neurosurgical intervention remains uncertain, as there is a lack of examination of pooled data from current literature despite validation in numerous single and multi-institutional studies. The aim of this study was to analyze existing studies to determine the diagnostic accuracy of BIG scoring criteria. A systematic review and meta-analysis was conducted in accordance with PRISMA guidelines (PROSPEROID CRD42021277542). Three databases were searched, and articles published from 2000 to October 2022 were included (last search date: 25 November 2022). Pooled sensitivity and specificity were calculated using random effects meta-analysis. Of the 1130 articles identified, 13 were included in the analysis (9032 patients – 1433 BIG1, 2136 BIG2 & 3189 BIG3). A total of 2274 patients were not classified under either group. Pooled sensitivity for predicting neurosurgical intervention was 1.00 (95%CI:1.00–1.00), and 0.98 for radiological deterioration (95% CI: 0.927–0.996). The specificity in predicting radiological deterioration was 0.18 (95% CI: 0.16–0.21) and 0.05 for neurosurgical intervention (95% CI 0.05–0.05). The BIG score is highly sensitive at excluding TBI cases that do not require neurosurgical intervention; however, BIG-2 and BIG-3 might not be useful for ruling in TBI patients who require neurosurgical intervention.

description: We revisit statistical wavefunction properties of finite systems of interacting fermions in the light of strength functions and their participation ratio and information entropy. For weakly interacting fermions in a mean-field with random two-body interactions of increasing strength $λ$, the strength functions $F_k(E)$ are well known to change, in the regime where level fluctuations follow Wigner's surmise, from Breit-Wigner to Gaussian form. We propose an ansatz for the function describing this transition which we use to investigate the participation ratio $ξ_2$ and the information entropy $S^{\rm info}$ during this crossover, thereby extending the known behavior valid in the Gaussian domain into much of the Breit-Wigner domain. Our method also allows us to derive the scaling law for the duality point $λ= λ_d$, where $F_k(E)$, $ξ_2$ and $S^{\rm info}$ in both the weak ($λ=0$) and strong mixing ($λ= \infty$) basis coincide as $λ_d \sim 1/\sqrt{m}$, where $m$ is the number of fermions. As an application, the ansatz function for strength functions is used in describing the Breit-Wigner to Gaussian transition seen in neutral atoms CeI to SmI with valence electrons changing from 4 to 8.
Robust Principal Component Analysis

description: In multivariate analysis, principal component analysis is a widely popular method which is used in many different fields. Though it has been extensively shown to work well when data follows multivariate normality, classical PCA suffers when data is heavy-tailed. Using PCA with the assumption that the data follows a stable distribution, we will show through simulations that a new method is better. We show the modified PCA can be used for heavy-tailed data and that we can more accurately estimate the correct number of components compared to classical PCA and more accurately identify the subspace spanned by the important components.

We examine the effects of three groups of variables (economic, social/demographic, and geography) on job growth, poverty, and median income. To this end, we split the time period before and after the Great Recession and use standard regression analysis augmented by quantile regressions to assess the heterogeneity in economic performance. The results suggest an increasing role played by economic factors including the benefits of having a fast-growing industry structure. Perhaps more importantly, measures of economic dynamics—the ability of a local economy to “rewire” by reallocating resources in response to economic shocks—emerge as important predictors of performance.

description: We construct a new family of N-fold supersymmetric systems which is referred to as ``type B''. A higher derivative representation of the N-fold supercharge for this new family is given by a deformation of the type A N-fold supercharge. By utilizing the same method as in the sl(2) construction of type A N-fold supersymmetry, we show that this family includes two of the quasi-solvable models of Post-Turbiner type.

title: Becoming a disabled mother: A qualitative longitudinal study
Creators: name: Hadfield, Lucy
Publisher: name: The Open University
Year: 2014

description: This thesis seeks to make sense of the complexity of the experience of becoming a disabled mother as made and lived in a dynamic process that is social, embodied, emotional, and temporal. There is limited empirical research that has investigated the experience of disabled motherhood and a relative absence of research that has followed disabled women's processes of identity over the course of the first year of motherhood. This thesis seeks to fill that gap. The empirical base for this thesis includes material collected from six longitudinal case studies, with disabled women interviewed three times in the first-year transition to becoming a mother. By focusing on what women do with their bodies, or their pursuit of distinct body projects, I reveal insights into my participants' experience and understanding of disability at this stage in the life-course, during which the embodied experience is subject to change and transformation. Drawing on post-structural concepts of power and agency, I explore the possibilities and limitations within my participants' strategies of sense-making for engineering a liveable life in relation to dominant social norms. These in sights speak to a debate within the disability movement about the nature of disability (as experience) as the basis of individual and collective identity and the kind of support disabled mothers need, which can inform social and healthcare practice. Methodologically, I utilise an innovative psycho-social longitudinal research design and method to enrich and develop my understanding of this process. Researcher subjectivity, difference and temporality are all regarded as important tools for revealing emotional dynamics and processes of intelligibility.
Sheaf Morphisms Induced by Dynamical Systems

description: Interrelated sets of data can be modeled in the form of a mathematical object called a sheaf. Essentially, a sheaf over a collection of sets represents a hypothesis about exactly how the data in those sets affect one another. This structure has many useful properties for data analysis and is the optimal way to think about the relationships between all sorts of data sets. Now similarly, a dynamical system acting on a set is a way of modeling relationships within a set of data and how they progress over time. Dynamical systems model many physical events or other patterns that can be found in the real world and can be used to make predictions about the future state of a set of data or even of many related sets of data. Bringing these two modeling concepts together we will demonstrate how, firstly, a dynamical system over a set of data can be represented in the form of a sheaf, and that doing so will provide all the analytic tools of sheaf theory to the study of that dynamical system. Secondly we will show that when such a sheaf is constructed, the progression of the time parameter of the dynamical system induces functions on the stalks of that sheaf and this set of new functions is in fact a sheaf morphism. Lastly we will show a few examples of this construction being done and how in some cases it can be done in more than one way.
Correlation exponent K_rho of the one-dimensional Kondo lattice model

description: We present results for the correlation exponent K_rho of the Tomonaga-Luttinger liquid description of the one-dimensional Kondo lattice as a function of conduction electron density and coupling constant. It is obtained from the first derivative of the Fourier transform of the charge-charge correlation function. We also show that the spin correlation function can only be described in this picture if we include logarithmic corrections, a feature that had been previously overlooked. A consistent description of both charge and spin sectors is then obtained. Finally, we show evidence that the spin sector of the dimerized phase at quarter-filling is gapless.

description: This paper examined the imbalances created by social situations and captured in the English language usage by the characters in Wole Soyinka’s The beatification of area boy. The play, set in the busy city of Lagos, is a theatrical typification of the Nigerian society that creates variety differentiation in language use. The sociolinguistic data for the analysis were extracted from the primary text. The findings indicate that, in the play, Soyinka succinctly displays characters as linguistic pointers to showcase the peculiarities in Nigerian English usage that differentiate the linguistic behaviours of Nigerians from other Englishes. The study reveals the categorisation of the ‘spoken’ varieties into Nigerian Pidgin, Incipient bilingual, Local colour variety and the Nigerian literary variety. These features which manifest at the phonological, semantic, lexical, syntactic and pragmatic levels altogether combine to represent the typical linguistic situation in a non-native speaker environment. The linguistic variations, when juxtaposed with sociolinguistic variables, explicitly express the domestic adaptations and modifications in English language usage suggestive of the playwright’s representation of the Nigerian multilingual society. Keywords: Nigerian English, English usage, varieties of English, sociolinguistic study, literature, wole soyinka
Computing the renormalization group flow of two-dimensional $ϕ^4$ theory with tensor networks

description: We study the renormalization group flow of $ϕ^4$ theory in two dimensions. Regularizing space into a fine-grained lattice and discretizing the scalar field in a controlled way, we rewrite the partition function of the theory as a tensor network. Combining local truncations and a standard coarse-graining scheme, we obtain the renormalization group flow of the theory as a map in a space of tensors. Aside from qualitative insights, we verify the scaling dimensions at criticality and extrapolate the critical coupling constant $f_{\rm c} = λ/ μ^2$ to the continuum to find $f^{\rm cont.}_{\rm c} = 11.0861(90)$, which favorably compares with alternative methods.

description: The purpose of this study was to assess the true cost of food at UBC. To do this, we created a set of indicators to evaluate negative externalities within the food system, using the model provided by 2003’s group 9 as a framework for our study. We determined that measuring externalities is a complex process. However, it is an important component of research into sustainability at UBC. Thus, we chose six indicators that we felt covered some of the most significant externalities associated with our food system. It will be important for future AGSC 450 classes to acknowledge the existence of these externalities, and our indicators will provide a basis upon which to analyze food system externalities in future studies.

description: Net farm income and net cash farm income, as well as the farm household’s income or loss from the farm business, are commonly used measures of farm financial performance. However, other factors may affect the household’s economic return from farming. Almost half of all farm households face a loss from the farm business in any given year, and those households can benefit from offsetting these tax losses. Households may also gain from appreciation of their assets, particularly farmland, depending on how much of their operated land is owned. This paper analyzes farm returns after adjusting for these factors, estimating the additional gains households receive from offsetting tax losses and asset appreciation. Economic returns are found to be higher for larger farms, and those with higher debt.
