description: Excerpts from the report Introduction: Markets in New York (principally New York City) and in northern New Jersey receive their milk supplies from a region that extends more than 400 miles from New York City. This milkshed--the largest of its kind in the world--includes the State of New York and parts of New Jersey, Pennsylvania, Vermont, Connecticut, Maryland, and Delaware. The milkshed provides the New York-New Jersey market with approximately 10 billion pounds of milk each year. This includes the output of more than 50,000 dairy farms. The task of getting this milk from these farms to the final consumers in the right form, at the right time, and at the right place is extremely large and complex. The firms, the plants, and the individuals who do this job comprise the dairy industry of the milkshed. The purpose of this report is to provide a more complete understanding of the organization and structure of the industry, and the functions and services it performs, for the guidance of those responsible for recommending or making changes in the milk marketing order to improve the efficiency of the market.

Creators: name: Shaohua Zhang
Publisher: name: Monash University
Year: 2019
Subjects: Uncategorized

description: Pultruded fibre reinforced polymer (GFRP) composite has been applied as a high-performance material. This research aims to contribute to the understanding of the dynamic response of pultruded GFRP at intermediate strain rates at the material and member scales. The effect of strain rate on the material properties of pultruded GFRP is studied via comprehensive experiments. At member scale, the dynamic response and application of pultruded GFREP are evaluated by experiments and finite element methods. The research outcomes will assist in the development of design guidelines for composite structures, and promote the adoption of pultruded GFRP in civil engineering.
Amplifying Phenomenal Information: Toward a Fundamental Theory of Consciousness
Creators: name: Gabora, L.
Publisher: name: arXiv
Year: 1999
Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)
subject: FOS: Physical sciences

description: Fundamental approaches bypass the problem of getting consciousness from non-conscious components by positing that consciousness is a universal primitive. For example, the double aspect theory of information holds that information has a phenomenal aspect. How then do you get from phenomenal information to human consciousness? This paper proposes that an entity is conscious to the extent it amplifies information, first by trapping and integrating it through closure, and second by maintaining dynamics at the edge of chaos through simultaneous processes of divergence and convergence. The origin of life through autocatalytic closure, and the origin of an interconnected worldview through conceptual closure, induced phase transitions in the degree to which information, and thus consciousness, is locally amplified. Divergence and convergence of cognitive information may involve phenomena observed in light e.g. focusing, interference, and resonance. By making information flow inward-biased, closure shields us from external consciousness; thus the paucity of consciousness may be an illusion.

description: We use the collective field theory known for the Calogero-Sutherland model to study a variety of low-energy properties. These include the ground state energy in a confining potential upto the two leading orders in the particle number, the dispersion relation of sound modes with a comparison to the two leading terms in the low temperature specific heat, large amplitude waves, and single soliton solutions. The two-point correlation function derived from the dispersion relation of the sound mode only gives its nonoscillatory asymptotic behavior correctly, demonstrating that the theory is applicable only for the low-energy and long wavelength excitations of the system.

description: The question of energy transition is one of the key issues in education for Sustainable Development. It is a socioscientific acute issue that is the subject of debate in the scientific, political and social spheres. The aim of this research is to evaluate, via a questionnaire submitted before and after the activity, how a teaching device centered around the energy transition is likely to modify students' representations of this issue. While there was little change in core representations, there was some enrichment in terms of the diversification of renewable energy production methods, with references to economic and environmental impacts.

description: Evapotranspiration has a major control on continental surfaces dynamics in forested boreal environments. For example, it has strong impacts on active layer thickness, mainly because of its effect on water content within the upper layers of the soil column. These are complex processes, depending not only on climate forcings (atmospheric water demand) but also on physical, geo-pedological and biological properties of the considered areas. Here we propose a numerical investigation of evapotranspiration processes in the active layer of slopes of a forested watershed in Central Siberia. The effect on actual evapotranspiration of the spatial contrasts in terms of exposure, root layer thickness and tree stand density within the watershed are simulated using a recently developed high performance computing cryohydrogeological model, permaFoam.
title: Prevalence and characteristics of work-anxiety in medical rehabilitation patients: a cross-sectional observation study

Subjects: subject: Workplace, mental health, anxiety, sick leave, work-oriented rehabilitation
subject: 150

description: Objective: To investigate frequency, type and characteristics of work-anxieties in somatic rehabilitation inpatients. Work-anxieties are serious disorders which affect occupational functioning and often go along with long-term sick leave. Somatic patients may suffer from work-related participation problems due to their chronic health condition. Work-anxieties need specific diagnostic and treatment.
Design: This is a cross-sectional observation study.
Setting: We investigated inpatients from a neurological, orthopedic and cardiologic rehabilitation clinic.
Participants: 1610 patients (18-65 years) were investigated for work-anxieties in a short structured interview.
Main outcome measures: Patients who scored high in at least two out of nine work-anxiety leading symptoms and reported impairment were investigated with a differential-diagnostic interview on work-anxieties, and with the MINI interview on non-work-related common mental disorders. Patients also filled in a self-rating on their subjective symptom load and sociodemographic data.
Results: About 20-27% of the investigated somatic rehabilitation inpatients (altogether n=393) got a work-anxiety diagnosis. Orthopaedic patients report highest work-anxiety and have longest preceding sick leave (20.6 weeks in past 12 months). Orthopaedic patients suffer from work-related adjustment anxieties, social anxieties, and workplace phobia, while cardiology patients are more often affected from hypochondriac anxieties. Anxieties of insufficiency and worrying occur equally in all indications.
Conclusions: About one quarter of somatic rehabilitation patients is in need of additional diagnostic attention due to work-anxieties. Differential diagnostic of work-anxiety is needed for initiating adequate therapeutic action. Somatic rehabilitation physicians should be aware of work-anxieties in their patients, especially in orthopaedic patients with preceding long-term sick leave.

description: Objective: To assess the accuracy of noninvasive parameters, fecal calprotectin (FC), increased bowel wall thickening (BWT) at intestinal ultrasound (IUS) and blood inflammatory indexes (BII), alone or in combination, as diagnostic tools for inflammatory bowel disease (IBD) in pediatric patients. Methods: Retrospective data were collected on consecutive children (age 2–18 years) referred to our pediatric gastroenterology clinic, for recurrent abdominal pain and/or altered bowel habit from 2007 to 2013. Subjects who had diagnostic workup: laboratory tests (FC, BII, white blood cell (WBC), C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)) and IUS as initial assessment were eligible. Subjects with known gastrointestinal (GI) diseases, or signs or symptoms highly suggestive for organic diseases necessitating prompt endoscopy (e.g., perianal disease or rectal bleeding), or who had recently performed endoscopy were excluded. The accuracy of noninvasive tests for detecting IBD was assessed using endoscopic and/or radiological investigations, performed in subsequent clinical follow up, as reference gold standard. Results: Seventy-seven patients (mean age 11.3, 44 males) were included, 23 (29.9%) with a final diagnosis of IBD. As single tests, FC gave the highest sensitivity (96%) but lower specificity (72%) and IUS highest specificity (96%) with lower sensitivity (70%). The combination of FC + IUS showed excellent accuracy for detecting children with IBD with positive predictive value: 100%; negative predictive value: 88.5%. The probability of IBD in children with normal FC, BII and IUS was 0.09%. Conclusions: FC and increased BWT at IUS are accurate to guide reassurance or proceeding with further invasive procedures for detecting IBD in children with mild GI symptoms.

description: This paper solves the problem of optimal dynamic consumption, investment, and healthcare spending with isoelastic utility, when natural mortality grows exponentially to reflect Gompertz' law and investment opportunities are constant. Healthcare slows the natural growth of mortality, indirectly increasing utility from consumption through longer lifetimes. Optimal consumption and healthcare imply an endogenous mortality law that is asymptotically exponential in the old-age limit, with lower growth rate than natural mortality. Healthcare spending steadily increases with age, both in absolute terms and relative to total spending. The optimal stochastic control problem reduces to a nonlinear ordinary differential equation with a unique solution, which has an explicit expression in the old-age limit. The main results are obtained through a novel version of Perron's method.

description: This article focuses on the acquisition of knowledge and the development of skills in technical drawing for learners of the first year of secondary school in technology class. It is a question of designing and testing a didactic engineering based on the investigation approach with the use of the SolidWorks volume modeler allowing learners to overcome obstacles and develop their knowledge and know-how. We have developed a learning project in two sequences whose validation is internal based on the confrontation between a priori analysis and a posteriori analysis with two groups of learners. This is a control group who attended a "hand" or traditional drawing course and another experimental group who benefited from a course integrating the 3D modeler. The analysis of the results showed the significant improvement in the level of the test group, supported by the 3D simulator SolidWorks, and made it possible to highlight the strong involvement of the learners allowing the construction of their knowledge and know-how in technical drawing.

description: Our work falls within the scope of research into the didactics of the physical sciences, and consists of the development of a filmed teaching sequence, integrating a classroom debate situation in a laboratry with third-year secondary school students in the context of teaching universal gravitation. Using video recordings and a cognitive didactics approach, our study aims to characterize the forms of interaction implemented in language productions enabling students to problematize and present reasoning likely to construct knowledge. This analysis has led us to better define the way in which gravitation theory is presented, while taking into account the learning problems encountered by the teacher during interactions with and between students on the subject, and highlighting the important role of language interactions as a socio-cognitive tool. It will also suggest ways of helping students to adopt a critical approach that breaks with their naïve conceptions.conceptions.

In contrast to other situations that describe the dynamics in Ising-like systems such as models A and B, we find that the dynamic exponent z=2 that governs the domain wall relaxation function is not equal to the inverse of the exponent n=1/4 that describes the coarsening process that leads to the steady state.

description: The root system architecture (RSA) has been reported to be determined by several root traits such as branching, elongation, and growth angle. This study aimed to evaluate the genotypic variation of plasticity in RSA in response to different soil water distributions in a soil profile. IR64 (shallow root system), YTH183 (adapted to rainfed lowland conditions due to high plasticity in root elongation), and Kinandang Patong (KP – deep root system) were grown in PVC root boxes for 34 days under continuously waterlogged conditions and with soil moisture fluctuations (SMF). For SMF, watering was done from the top of the root box (TI-SMF) or from the bottom of the root box (BI-SMF). A water gradient was observed more clearly in BI-SMF than in TI-SMF, while mean soil moisture content in the root box was kept at around 23% (v/v) after first irrigation in both SMF treatments. RSA changed drastically with SMF in all cultivars, all of which tended to shift root distribution to deeper soil layers in response to SMF. Such changes in RSA resulted from different degrees of plasticity exhibited mainly in nodal root and L-type lateral root development. YTH183 showed a greater ability to change its root growth angle and thus its root distribution in the deeper soil layer compared to IR64 and KP under SMF, indicating that YTH183 could help to improve RSA in cultivars adapted to SMF.
Designing teaching activities based on the precursor model for electricity in early childhood education

Subjects: Early Childhood Science Education, precursor model, teaching activities, electricity

description: The aim of this study is to describe a context for developing teaching activities for electricity in early childhood education. It leverages the concept of the precursor model, which comprises mental representations exhibiting characteristics of naive knowledge while also incorporating elements compatible with scientific models. Data from three studies are utilized, demonstrating that the precursor model of preschool-aged children for electricity exhibits phenomenological features, where children: a) empirically approach electricity as an entity that causes specific effects, b) perceive it as something that can be transported, c) conceptualize the technical components of an electric circuit, and d) construct simple electric circuits. For this reason, a framework for developing instructional activities is proposed, emphasizing technology and children's actions on objects rather than the construction of pre-scientific mental models based on a microscopic level.

description: Excerpts from the report Summary: This study evaluates the effect of tandem lint cleaning on the grade of cotton and hale values at different levels of premiums and discounts, and the effects of this cleaning on bale weight and average price per pound. The study was undertaken as part of a broad marketing research program aimed at increasing marketing efficiency and expanding the market for farm products. The study was conducted in east-central Arkansas during the ginning seasons of 1957-58 and 1958-59. During these two seasons, 413 bales of cotton were sampled at 4 gins. Samples of lint were taken from each bale before any lint cleaning, after one lint cleaning, and after two lint cleanings. The classification of these samples, together with the weight of waste removed by the lint cleaners, provided the basis for evaluating the effects of these machines. The gins were similarly equipped, with fairly elaborate overhead cleaning and conditioning equipment.

description: Modern information and communication systems have become increasingly challenging to manage. The ubiquitous system logs contain plentiful information and are thus widely exploited as an alternative source for system management. As log files usually encompass large amounts of raw data, manually analyzing them is laborious and error-prone. Consequently, many research endeavors have been devoted to automatic log analysis. However, these works typically expect structured input and struggle with the heterogeneous nature of raw system logs. Log parsing closes this gap by converting the unstructured system logs to structured records. Many parsers were proposed during the last decades to accommodate various log analysis applications. However, due to the ample solution space and lack of systematic evaluation, it is not easy for practitioners to find ready-made solutions that fit their needs.
 This paper aims to provide a comprehensive survey on log parsing. We begin with an exhaustive taxonomy of existing log parsers. Then we empirically analyze the critical performance and operational features for 17 open-source solutions both quantitatively and qualitatively, and whenever applicable discuss the merits of alternative approaches. We also elaborate on future challenges and discuss the relevant research directions. We envision this survey as a helpful resource for system administrators and domain experts to choose the most desirable open-source solution or implement new ones based on application-specific requirements.

description: Objective: Up to 29% of the working population suffer from (chronic) mental disorders and work disability. As different professions pose different psychological capacity demands, one core aspect for describing work disability is psychological capacity limitations. The distribution of capacity limitations in patients with chronic mental disorders (CMD) from different professional fields is unknown, as well as their relation with sick leave.
Objective: Are there different work ability limitations in CMD patients working in different professions?
Methods: 263 CMD patients from different professions were investigated cross-sectionally in a thorough medical and psychological assessment by a trained psychosomatic study physician. Besides CMD diagnostic (MINI) and subjective work ability limitations (IMET), an observer rating on capacity limitations was conducted with Mini-ICF-APP.
Results: No relevant differences in perceived work ability limitations were found between the professions. Differences of capacity limitations were better explained by psychopathology than by profession. But capacity limitations were differently related with sick leave in different professions and there are differences in sick leave duration.
Conclusions: The variance of capacity limitations was explained by psychopathology. The variance of sick leave duration was explained by profession. Similar capacity limitations are associated differently with sick leave in different professions. Different professional fields may have different tolerances towards the same capacity limitations. Therefore, similar capacity limitations are more or less strongly associated with sick leave in different professions.

description: We investigated herb and woody species at rehabilitated forests planted by mahogany and teak, and original, not rehabilitated forests in Yogyakarta, Indonesia. Plant species were classified into five use categories: medicine, food, fodder, ornament, and construction. We registered 142 species belonging to 54 families known as useful species with at least one, often more, use categories. The number of useful species was highest for medicine use (107 species). There was a dominance of exotic herb species used for food and annual herbs used for fodder. The number of useful herbs and exotic woody species was highest in teak stands. The number of woody species used for medicine, food, and construction was higher than those for ornament and fodder. All herb species decreased with time, except annual native, that increased. Around 50% of the useful species occurred only once in one site, and some species showed a distribution restricted to one type of stands. Overall, our results seem to show that rehabilitated stands are doing well with regard to useful herb and woody species. We suggest strategies for plant and ecosystem conservation, especially for rare native plant species and species with restricted distribution.

Modelling Collective Opinion Formation by Means of Active Brownian Particles

Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)

description: The concept of active Brownian particles is used to model a collective opinion formation process. It is assumed that individuals in community create a two-component communication field that influences the change of opinions of other persons and/or can induce their migration. The communication field is described by a reaction-diffusion equation, the opinion change of the individuals is given by a master equation, while the migration is described by a set of Langevin equations, coupled by the communication field. In the mean-field limit holding for fast communication we derive a critical population size, above which the community separates into a majority and a minority with opposite opinions. The existence of external support (e.g. from mass media) changes the ratio between minority and majority, until above a critical external support the supported subpopulation exists always as a majority. Spatial effects lead to two critical ``social'' temperatures, between which the community exists in a metastable state, thus fluctuations below a certain critical wave number may result in a spatial opinion separation. The range of metastability is particularly determined by a parameter characterizing the individual response to the communication field. In our discussion, we draw analogies to phase transitions in physical systems.

Subjects: Responsible technological innovation, technological education, curriculum, didactic

description: This article presents two small-scale exploratory studies that aim to investigate how technological innovation is approached in secondary technological education, both in the curriculum prescribed by educational programs and in the declared practices of teachers. Two complementary methodological approaches are used: curriculum analysis and semi-structured interviews with six teachers. Computerized textual data analysis was employed in both studies. The curriculum study reveals that technological innovation, despite being established as a curricular organizer, struggles to find a place in the specific expectations of the program. The notion of technological innovation also remains implicit. In response to these findings, the semi-structured interviews shed light on a variety of declared practices among teachers regarding the teaching of technological innovation. The article suggests the possibility of expanding education on technological innovation towards responsible technological innovation education.

description: A model for the motion of ring-shaped DNA in a gel is introduced and studied by numerical simulations and a mean-field approximation. The ring motion is mediated by finger-shaped loops (hernias) that move in an amoeba-like fashion around the gel obstructions. This constitutes an extension of previous reptation tube treatments. It is shown that tension is essential for describing the dynamics in the presence of hernias. It is included in the model as long range interactions over stretched DNA regions. The mobility of ring-shaped DNA is found to saturate much as in the well-studied case of linear DNA. Experiments in polymer gels, however, show that the mobility drops exponentially with the DNA ring size. This is commonly attributed to dangling-ends in the gel that can impale the ring. The predictions of the present model are expected to apply to artificial 2D obstacle arrays (W.D. Volkmuth, R.H. Austin, Nature 358,600 (1992)) which have no dangling-ends. In the zero-field case an exact solution of the model steady-state is obtained, and quantities such as the average ring size are calculated. An approximate treatment of the ring dynamics is given, and the diffusion coefficient is derived. The model is also discussed in the context of spontaneous symmetry breaking in one dimension.

description: We report the BeppoSAX observations of 6 Flat Spectrum Radio Quasars. Three of them have a clear detection up to 100 keV with the PDS instrument. For 4 objects the X-ray spectrum is satisfactorily fitted by a power-law continuum with Galactic absorption. 2251+158 show the presence of absorption higher than the galactic value, while the spectrum of the source 0208-512 shows a complex structure, with evidence of absorption at low energy. We construct the Spectral Energy Distributions adding historical data to the broad band X-ray spectra obtained with $Beppo$SAX and reproduce them with a one-zone Synchrotron-Inverse Compton model (including both SSC and External Compton). The implications are briefly discussed.

Subjects: Power generation systems, virtual reality, immersive learning environment, pre-service teachers' conceptions

description: Virtual environments offer innovative and promising solutions for natural science education, benefiting both students and teachers. Research indicates that pre-service teachers struggle to visualize and describe power generation processes, potentially passing on alternative conceptions to students. This study focuses on the design, development, and evaluation of a 3D virtual reality learning environment for large-scale power generation systems, specifically steam power plants. Following an "innovative" teaching framework, the study aimed to explore and reconstruct pre-service teachers' conceptions through interaction with the immersive virtual environment. The research procedure involved four parts of a semi-structured interview with pre-service teachers exploring their ideas and whose analysis results confirm  existing literature on alternative conceptions. The study highlighted cognitive progress, especially in the technological dimension of power generation systems using the virtual reality learning environment.

description: We report on the experimental study and numerical analysis of chiral light-matter coupling in deterministically fabricated quantum dot (QD) waveguide structures. We apply in-situ electron beam lithography to deterministically integrate single InGaAs/GaAs QDs into GaAs-DBR waveguides to systematically explore the dependence of chiral coupling on the position of the QD inside the waveguide. By a series of micro-photoluminescence measurements, we determine the directionality contrast of emission into left and right traveling waveguide modes revealing a maximum of 0.93 for highly off-center QDs and an oscillatory dependence of this contrast on the QD position. In numerical simulations we obtain insight into chiral light-matter coupling by computing the light field emitted by a circularly polarized source and its overlap with multiple guided modes of the structure, which enables us to calculate directional $β$-factors for the quantum emitters. The calculated dependence of the directionality on the off-center QD position is in good agreement with the experimental data. It confirms the control of chiral effects in deterministically fabricated QD-waveguide systems with high potential for future non-reciprocal on-chip systems required for quantum information processing.

Massless and quantized modes of kinks in the phase space of superconducting gaps

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We investigated quantized modes of kinks in the phase space of superconducting gaps in a superconductor with multiple gaps. The kink is described by the sine-Gordon model in a two-gap superconductor and by the double sine-Gordon model in a three-gap superconductor. A fractional-flux vortex exists at the edge of the kink, and a fractional-flux vortex will be stable in a three-gap superconductor with time-reversal symmetry breaking. The kink and fractional-flux vortex exhibit massless modes as a sliding motion. We show further that there are one zero-energy mode (massless mode) and quantized excitation modes in kinks, which are characteristic features of multi-gap superconductors. The equation of quantized modes for the double sine-Gordon model is solved numerically. The correction to the ground-state energy is calculated based on the renormalization theory.

description: Work perception is an important predictor for work ability and therefore of interest for rehabilitation. Until now it is unclear to which extent different psychological aspects explain work perception. This study investigates in which way workplace problems on the one hand, and mental health and coping on the other hand, contribute to work perception.
A heterogeneous sample of 384 persons in working age with and without mental health problems was recruited. Participants gave self-reports on workplace problems, mental health problems, work-coping, work-anxiety, and work perception.
Persons with mental health problems and workplace problems (M+W) perceive the highest degree of work demands, followed by persons with workplace problems but without mental health problems (NM+W). Work-anxiety appeared as the strongest factor explaining perception of high work demands, whereas general mental health problems did not contribute significantly to variance explanation.
Persons with specific mental health problems in terms of work-anxiety may be expected to perceive higher work demands. They may be detected when asking for work perception, e.g. within the frame of return-to-work interventions in rehabilitation, or in occupational health settings by mental hazard analysis.

description: Given a set system $\mathcal{X} = \{\mathcal{U},\mathcal{S}\}$, where $\mathcal{U}$ is a set of elements and $\mathcal{S}$ is a set of subsets of $\mathcal{U}$, an exact hitting set $\mathcal{U}'$ is a subset of $\mathcal{U}$ such that each subset in $\mathcal{S}$ contains exactly one element in $\mathcal{U}'$. We refer to a set system as exactly hittable if it has an exact hitting set. In this paper, we study interval graphs which have intersection models that are exactly hittable. We refer to these interval graphs as exactly hittable interval graphs (EHIG). We present a forbidden structure characterization for EHIG. We also show that the class of proper interval graphs is a strict subclass of EHIG. Finally, we give an algorithm that runs in polynomial time to recognize graphs belonging to the class of EHIG.
