description: At large values of x the parton distribution functions (PDFs) of the proton are poorly constrained and there are considerable variations between different global fits. Data at such high x have already been published by the ZEUS Collaboration, but not yet used in PDF extractions. A technique for comparing predictions based on different PDF sets to the observed number of events in the ZEUS data is presented. It is applied to compare predictions from the most commonly used PDFs to published ZEUS data at high Bjorken x. A wide variation is found in the ability of the PDFs to predict the observed results. A scheme for including the ZEUS high-x data in future PDF extractions is discussed.

HCN Survey of Normal Spiral, IR-luminous and Ultraluminous Galaxies

description: We report systematic HCN J=1-0 (and CO) observations of a sample of 53 infrared (IR) and/or CO-bright and/or luminous galaxies, including seven ultraluminous infrared galaxies, nearly 20 luminous infrared galaxies, and more than a dozen of the nearest normal spiral galaxies. This is the largest and most sensitive HCN survey of galaxies to date. All galaxies observed so far follow the tight correlation between the IR luminosity $L_{\rm IR}$ and the HCN luminosity $L_{\rm HCN}$ initially proposed by Solomon, Downes, & Radford, which is detailed in a companion paper. We also address here the issue of HCN excitation. There is no particularly strong correlation between $L_{\rm HCN}$ and the 12$μ$m luminosity; in fact, of all the four \IRAS bands, the 12$μ$m luminosity has the weakest correlation with the HCN luminosity. There is also no evidence of stronger HCN emission or a higher ratio of HCN and CO luminosities $L_{\rm HCN}/L_{\rm CO}$ for galaxies with excess 12$μ$m emission. This result implies that mid-IR radiative pumping, or populating, of the J=1 level of HCN by a mid-IR vibrational transition is not important compared with the collisional excitation by dense molecular hydrogen. Furthermore, large velocity gradient calculations justify the use of HCN J=1-0 emission as a tracer of high-density molecular gas ($\approxgt 3\times 10^4/τ$ cm$^{-3}$) and give an estimate of the mass of dense molecular gas from HCN observations. Therefore, $L_{\rm HCN}$ may be used as a measure of the total mass of dense molecular gas, and the luminosity ratio $L_{\rm HCN}/L_{\rm CO}$ may indicate the fraction of molecular gas that is dense.

description: Background: It is widely accepted that adversities during development may impact depression in adulthood, but its relations with current depression triggers are unclear. The present research aimed to explore the association between self-reported adverse childhood and adolescent experiences with self-reported depressive triggers, according to interpersonal classification, in depressed women. Methods: The sample consisted of 822 women with Depressive Disorders, who attended Psychotherapy at a Central Hospital in Lisbon (Portugal). Problems in childhood and adolescence and triggering factors were obtained through open-ended questions from a psychotherapy screening questionnaire. Descriptive statistics and Pearson´s correlation coefficients were calculated. Results: The most commonly reported adversities in childhood and adolescence took place in the family context, namely and in order of frequency, family conflicts, relational difficulties between parents and children and family violence. Higher reports of significant problems at an early age were associated with higher reports across development. Higher reports of interpersonal disputes as depressive triggers were associated with higher reports of interpersonal disputes problems during childhood and adolescence. Conclusion: Interpersonal disputes seem a major precursor of depressive symptomatology in women later in life. The classification of childhood and adolescent problems and depression triggers according to interpersonal theory proved to be a consistent association criterion and allowed us to assess priority intervention areas in depressed patients, such as interpersonal disputes and role transitions. This study highlights the unmet needs of families, that could be a target for conflict management and interpersonal communication intervention programs early in parental-child relationships. This is an important contribute to the development of family-friendly public policies and action plans.

title: Effects of Farming Practices on the Transfer of Phosphorus in Rural Catchments
Creators: name: Withers, Paul John Anthony
Publisher: name: The Open University
Year: 2008

description: To better understand the role of agriculture in the eutrophication of surface waters, the spatial and temporal variation in P concentrations in streams and storm runoff was examined in relation to historic and current farming practices (upland pasture improvement, soil P accumulation, soil cultivations and fertiliser and manure inputs) and other sources of P (farmyards, road runoff and wastewater discharge) in a number of small rural catchments in England. In an upland pasture catchment and a lowland mixed farming catchment, soil P was the major source of P export rather than annual field operations which generally did not coincide with the main periods of hydrological connectivity. The majority of P transfer was in particulate form (>0. 45 pm), although field plot investigations suggested this form of P was relatively insensitive to differences in soil P fertility as compared to the dissolved P fraction, and may release P to the watercolumn even at low soil P concentrations. Three mitigation options (early sowing, reduced cultivations and tramline removal) for reducing soil particulate P transfer were compared at the field scale. All three options had positive effects. Early crop establishment was the most effective, but not consistently so, suggesting a combination of measures is required on farms. Analysis of 118 storm runoff samples showed that farmyard and road runoff, and runoff receiving wastewater (septic tank) discharges were more concentrated in P than surface and sub-surface runoff from agricultural fields. These sources also arrive more continuously through the year and therefore are potentially more ecologically damaging than runoff from farmed land. It is concluded that urbanisation maybe a greater threat to eutrophication than agricultural intensification even in small rural catchments and that effective, integrated catchment management requires collective social responsibility to tackle the multiple sources of P entering water and not just the targeting of the farming community.

description: The use of modern technologies as instructional tools is becoming increasingly prevalent in both general and special education. This systematic review examines the effects of computer-assisted and digital training on competency enhancement for adults with intellectual disabilities. As opposed to mere knowledge, “competency” was defined as the ability to apply and employ acquired knowledge to carry out tasks and solve problems in professional, social, and personal life domains. The PRISMA procedure was used to search for records dealing with competency enhancement using computerized training for intellectually disabled adults. Twenty-two articles met the inclusion criteria, showing that contemporary technology, computer-based tools, and digital instruments can positively affect the quality of life of adults with intellectual disabilities, and enhance their personal, professional, and social competencies. Ultimately, fostering computer-based technology to enhance competencies in adults with intellectual disabilities appears to be very promising, in that it allows these individuals to better integrate into society and live more independently, autonomously, and effectively.

description: Background: A growing body of literature shows relationships between behavioral problems and pragmatic abilities in children with neurodevelopmental disorders. However, the link between pragmatic skills, school well-being and psychological health in typically developing children is still under explored. The present study was aimed at an analysis of the relationships between well-being, behavioral problems, and pragmatics in Italian children from the general population. Methods: The sample included sixty typically developing children, their mothers, and their teachers. The mothers completed the Children’s Communication Checklist, second edition, the Questionnaire on School Well-being and the Child Behavior Checklist, questionnaires that evaluate children’s pragmatic abilities, school well-being, and psychopathological symptoms, respectively. The teachers completed the Questionnaire on School Well-being. Results: Close relationships between pragmatic abilities and school well-being were found. In particular, according to both mothers and teachers, Stereotyped language and Use of context were the two pragmatic variables most strongly associated with school well-being. Pragmatic abilities were also linked to externalizing and internalizing symptoms and with specific behavioural problems such as social and attentional problems. Conclusions: This study sheds light on the close relationships between pragmatic abilities and school well-being and psychological health in typically developing children. We discuss the relevance of focusing attention on early pragmatic competences in children and the importance of considering the school as a crucial setting for psychological assessment and interventions.

description: Excerpts from the report: In 1951 the second most abundant crop of fresh western plums on record, combined with low prices, focused attention on the relatively high cost of shipping containers for this fruit. The cost of the standard 4-basket crate and the cost of packing and loading it amounted to only a few cents less than the entire on-tree per crate return to the grower for his plums. The skilled labor required for eye-sizing and hand-packing the plums individually in each of the four baskets not only was costly, but frequently was inadequate to keep the fruit flowing smoothly from the pickers to the waiting refrigerator cars. This research project was undertaken to develop a shipping container which would be less expensive than the one in general use and which also would permit savings in packing and loading costs. An equally important objective was to develop a container which maximized the salability of the plums.

description: Agriculture in South Africa plays a minor role in terms of contribution to gross domestic product. Amongst others for this reason, agriculture is only reflected as a single production activity in the South African input-output tables. This may understate'the possibility that a large number of production activities depend on agriculture. For this purpose the term agribusiness is introduced. A special inputoutput table is presented with particular emphasis on agribusiness in South Africa. This input-output table is used to highlight the relative importance of agribusiness by means of simple linkage analysis. The results show that agribusiness is relatively more important in terms of backward linkages and employment multipliers. Finally, these results are discussed in the context of a possible agriculture-demand-led industrialisation strategy. The relevance of such a strategy for South Africa remains to be seen, although certain elements are supported by the results of the simple linkage analysis.

description: Recent three-dimensional radiation hydrodynamic simulations by Wedemeyer et al. (2004) suggest that the solar chromosphere is highly structured in space and time on scales of only 1000 km and 20-25 sec, resp.. The resulting pattern consists of a network of hot gas and enclosed cool regions which are due to the propagation and interaction of shock fronts. In contrast to many other diagnostics, the radio continuum at millimeter wavelengths is formed in LTE, and provides a rather direct measure of the thermal structure. It thus facilitates the comparison between numerical model and observation. While the involved time and length scales are not accessible with todays equipment for that wavelength range, the next generation of instruments, such as the Atacama Large Millimeter Array (ALMA), will provide a big step towards the required resolution. Here we present results of radiative transfer calculations at mm and sub-mm wavelengths with emphasis on spatial and temporal resolution which are crucial for the ongoing discussion about the chromospheric temperature structure.

description: We study the hydrodynamics of spherical spinners suspended in a Newtonian fluid at inertial regime. We observe a spontaneous condensation of the spinners into particle rich regions, at low but finite particle Reynolds numbers and volume fractions. The particle clusters have a coherent internal dynamics. The spinners form colloidal vortices surrounded by the fluid depleted of the particles. The formation of vortices is observed both in periodic simulation box and when the spinners are confined between two flat walls. The stabilisation of the observed states relies only on hydrodynamic interactions between the spinners and requires a finite amount of inertia. The observations pave the way for the realisation of 3-dimensional spinner materials, where coherent structures and collective dynamics arise only from the rotational motion of the constituents.

It is also suggested that this higher order derivative is of intrinsic interest in that it gives an additional characteristics of the KT transition which might be associated with a universal number akin to the universal value of the helicity modulus at the critical temperature.

description: The marketing of wheat has been controlled by the Wheat Board since 1935 and wheat is currently marketed through a one channel fixed price scheme. In this paper various market scenarios for wheat in South Africa are simulated with the use of a regional linear programming model which incorporates negative-sloping demand functions, substitution in demand between wheat and maize, and income risk. The model is used to predict changes in product prices, production levels, location of production and welfare transfers under the different market scenarios. A free market simulation showed a distortion in production patterns of the major crops caused by the price support policy. The domestic free market equilibrium price of wheat was predicted to be about 15 per cent lower than the mean fixed price. Owing to the strong price relationship between wheat and maize there is no significant decrease in the wheat price in a free market for winter cereals only and when maize is the only crop marketed under a fixed price system. The social cost analysis showed clearly that to reduce social costs a combined marketing policy for wheat and its related industries is required.

description: The purpose of this paper is to conduct an exploratory analysis of certain observable measures associated with farm labour management and to examine factors affecting farm labour remuneration. Data were collected in the Lions River, Lower Tugela and Elliot magisterial districts during January 1987. A principal components analysis extracted a factor common to measures of positive farmer attitude, called a "progressive labour management index", which implied that farmers who use labour training facilities also provide incentive schemes, give generous leave allowances and would consider employing an African farm manager. A regression analysis is used to determine factors affecting remuneration levels. A principal component which extracts 67.4% of variation in remuneration is used as the dependent variable. Variables tested included labourer training, years work experience, farmer's attitude and farm type. Training and years work experience were significant in all three areas and positively correlated with remuneration.

description: The monetary approach to exchange rate determination has been criticised because of the lack of empirical evidence. In this research note, a linear regression equation was estimated according to the monetary approach to explain changes in the nominal United States dollar/rand exchange rate for the years 1960-1988. Results indicate that this exchange rate is determined by relative United States and South African money supplies, nominal interest rates and real incomes. The R2 value was 0.965 percent.

description: Road accidents are a major emergency in Europe, and several studies investigating road trauma victims have demonstrated their serious psychological consequences and their incidence related to several serious psychological disorders (e.g., anxiety disorders, depression, psychoactive substance abuse, Acute Stress Disorder and Post-Traumatic Stress Disorder). The quality of assistance provided to the victims immediately after the event is crucial for both short- and long-term psychological consequences and can often explain the causes of post-traumatic morbidity. Based on these considerations, the paper presents a scientifically grounded early psychological intervention program that is specifically designed for road accident victims: ANIACARES. ANIACARES provides psychosocial support to road trauma victims who suffered serious injuries and/or to their relatives. This model is inspired by the most-investigated protocols related to first-aid psychology, crisis intervention, and trauma-focused psychological interventions. ANIACARES aims to reduce the possible post-traumatic psychological effects, as well as to limit the decline in the life quality of family members, and of the seriously traumatized, by providing psychological counselling and support. The program aims to support the victims during the different phases of the traumatic event to foster better emotion regulation strategies, to facilitate communication between victims and rescue personnel, to promote adherence to medical care, to promote the mourning process, to prevent the onset of post-traumatic psychopathologies, and to promote the resolution of conflicts. The validity of the model was evaluated by presenting the pre-and post-intervention results, focusing on several aspects of the individual’s well-being investigated on 125 road trauma victims categorized as Direct Victims, Indirect Victims with seriously Injured family members, and Indirect Victims with a Deceased family member. Results allow to support the validity of ANIACARES; in fact, an improvement in the general conditions of psychological health and well-being of the victims has been shown and on dimensions which mood and affectivity, memory, and speech. The relevance of ANIACARES does not lie solely in developing “new” clinical techniques or procedures, but rather in structuring a specific model of psychological support and supportive intervention for a population that is too often overlooked and on which the possible outcomes are well known.

description: In a dynamic world of change, promotion of agricultural commodities will inevitably become more important, particularly with respect to intensification in the nature of competition, the complexity in distribution and differences between consumer and producer prices. The impact of advertising as a means of promoting agricultural commodities, have to be evaluated in terms of consumer response and the effectiveness of advertising agricultural products, by assuming that advertising can increase the level of sales at any given price by shifting the demand curve for a specific product to the right, or increase the price or both. Although South Africa is a part of Africa, it has a highly developed and sophisticated marketing structure which necessitates the analysis and decomposition of foreign advertising research done in Europe and America for possible application in South Africa, due to the virtually non-existence of research on generic or brand advertising of agricultural products in South Africa. Empirical research on the effects of advertising generally indicates a positive effect on sales that continues beyond the time of initial advertising. Most analyses considering the effect of advertising on consumer demand for agricultural commodities have pragmatically focused on single-equation demand relations using aggregate data. However, limitations of the single equation approach exists. In general, empirical evidence shows that brand advertising is more efficient than generic advertising.

description: Recent advances in DNA sequencing and fluorescence imaging have made it possible to monitor the dynamics of ribosomes actively engaged in messenger RNA (mRNA) translation. Here, we model these experiments within the inhomogeneous totally asymmetric simple exclusion process (TASEP) using realistic kinetic parameters. In particular we present analytic expressions to describe the following three cases: (a) translation of a newly transcribed mRNA, (b) translation in the steady state and, specifically the dynamics of individual (tagged) ribosomes and (c) run-off translation after inhibition of translation initiation. In the cases (b) and (c) we develop an effective medium approximation to describe many-ribosome dynamics in terms of a single tagged ribosome in an effective medium. The predictions are in good agreement with stochastic simulations.

description: The demand for scientific economic analysis has led to a research emphasis of using empirical procedures on historic phenomena. More rigorous economic analyses are required on the present and emerging problems of society. The challenges facing agricultural economists in South Africa are daunting and more scholarly papers are required on these issues. The rigour of economic discipline, coupled with the refereeing process in scholarly journals, will promote research ethics based on objectivity and the search for truth. These are especially relevant where policy issues are politicized. The availability of sophisticated computer programmes has led to the repetitive application of research technology. The MOTAD technique, for example, now appears to be going out of fashion. More theoretical insight and better research tools are required.

description: Group 15 was assigned to scenario 7, “Identifying a Direction of Food System Education Outreach at Sprouts.’’(UBCFSP, 2010) The group met with Sprouts Coordinators, who identified the Sprouts Box and the Buying Club for the group to work on. The task for Sprouts box was to expand cliental base and help to expand box program. The main focus in regards to the Buying Club was to attract more customers. The group did the on-line research of other box program and buying clubs. Group members sent emails to some clubs at UBC to introduce Buying Club. The main findings in regards to these two programs were that outreach was lacking, and several aspects of these programs make them inaccessible to some people: Sprouts boxes come in 2 sizes only; all boxes contain the same food items, which may not be appropriate for everyone; the buying club is for large groups only and is not appropriate for individuals. Communication between both the Sprouts Box and Buying Club members was lacking. We have the following recommendations: Sprouts Box can make the program convenient by offering more than one pick-up time; offer a variety of both box sizes and content variety; and increase the communication among its customers by online communication tools. Our recommendations in regards to the buying club and Sprouts box outreach initiatives are to distribute flyers around campus, develop a short presentation for a pre-class lecture and set up a promotional booth around campus to advertise these two programs.

description: Conventional optical synthesis, the manipulation of the phase and amplitude of spectral components to produce an optical pulse in different temporal modes, is revolutionizing ultrafast optical science and metrology. These technologies rely on the Fourier transform of light fields between time and frequency domains in one-dimensional space. However, within this treatment it is impossible to incorporate the quantum correlation among photons. Here we expand the Fourier synthesis into high dimensional space to deal with the quantum correlation, and carry out an experimental demonstration by manipulating the two-photon probability distribution of a biphoton in two-dimensional time and frequency space. As a potential application, we show manipulation of a heralded single-photon wave packet, which is never explained by the conventional one-dimensional Fourier optics. Our approach opens up a new pathway to tailor the temporal characteristics of a biphoton wave packet with high dimensional quantum-mechanical treatment. We anticipate such high dimensional treatment of light in time and frequency domains could bridge the research fields between quantum optics and ultrafast optical measurements.

description: We show that for all very special quaternionic manifolds a different N=1 reduction exists, defining a Kaehler Geometry which is ``dual'' to the original very special Kaehler geometry with metric G_{a\bar{b}}= - \partial_a \partial_b \ln V (V={1/6}d_{abc}λ^a λ^b λ^c). The dual metric g^{ab}=V^{-2} (G^{-1})^{ab} is Kaehler and it also defines a flat potential as the original metric. Such geometries and some of their extensions find applications in Type IIB compactifications on Calabi--Yau orientifolds.

description: Background: Research has found that parental failures of care during childhood and insecure attachment styles are positively associated with problematic gaming. From a developmental framework, it is possible to hypothesize that attachment styles mediate the relationship between parental bonding and problematic gaming. Methods: This hypothesis was tested in a sample of 598 videogame players (410 males, 68.56%) aged between 18 and 61 years old (M = 26.68, SD = 7.23). Participants were recruited through an online survey. Self-report instruments were administered to assess problematic gaming, parental bonding, and adult attachment styles. Results: Positive paternal care was a direct and negative predictor of problematic gaming, whereas maternal overprotection indirectly predicted problematic gaming through preoccupied attachment. Conclusions: These findings suggest that positive paternal care represents a protective factor for problematic gaming; in contrast, maternal overprotection might foster a negative view of the self in the child, which increases the risk to excessively use videogames, perhaps as a maladaptive coping strategy to regulate negative feelings. Prevention programs might be aimed to improve the responsiveness of parents towards the child’s emotional needs, to prevent the development of problematic gaming. Also, clinical intervention with problematic gamers might foster their feelings of security toward relationships, to promote both a healthier use of videogames and a better quality of life.

The Italian version of the Questionnaire for the Assessment of Self-Disgust
Creators: name: Schienle, Anne
name: Wabnegger, Albert

Publisher: name: Mediterranean Journal of Clinical Psychology
Year: 2021
Subjects: Self-disgust; Questionnaire; Depression; Anxiety; Somatization; Body image concerns.

description: Objectives: While disgust directed at potential disease elicitors constitutes an adaptive mechanism for health protection, disgust directed against the own person is dysfunctional, particularly when it becomes an enduring cognitive-affective orientation toward the self. Self-disgust is associated with several mental disorders, such as depression, borderline personality disorder, eating disorders, obsessive-compulsive and related disorders, and posttraumatic stress disorder. Therefore, the assessment of this construct in the clinical context is very important. Since a Questionnaire for the Assessment of Self-Disgust (QASD) in Italian did not exist, such a scale was developed. Methods: A total of 1053 individuals (mean age = 32 years; 76% female) participated in an online survey. They completed questionnaires for the assessment of self-disgust (the translated version of the German QASD, Schienle, Ille, Arendasy, 2014), psychological problems, and overall mental well-being. An exploratory factor analysis (principal axis estimation with oblique (oblimin) rotation; n = 526) and confirmatory factor analysis (n = 527) were computed. Moreover, correlation analyses were carried out to assess the relationship between self-disgust and different indicators of mental wellbeing and psychological disorders. Results: The QASD has a single factor structure. The questionnaire assesses disgust directed against the own body, personality, and behavior with 12 items. The QASD has very good reliability (McDonald´s omega = .92). The mean self-disgust scores correlated positively with reported symptoms of depression, anxiety, somatization, and body image concerns, and negatively with overall mental wellbeing. Conclusion: The results point to the association between elevated self-disgust and psychological problems. Therefore, the scale should now be administered in clinical samples.

Sensitivity of the lower-edge of the pair instability black hole mass gap to the treatment of time dependent convection

description: Gravitational-wave detections are now probing the black hole (BH) mass distribution, including the predicted pair-instability mass gap. These data require robust quantitative predictions, which are challenging to obtain. The most massive BH progenitors experience episodic mass ejections on timescales shorter than the convective turn-over timescale. This invalidates the steady-state assumption on which the classic mixing-length theory relies. We compare the final BH masses computed with two different versions of the stellar evolutionary code \texttt{MESA}: (i) using the default implementation of \cite{paxton:18} and (ii) solving an additional equation accounting for the timescale for convective deceleration. In the second grid, where stronger convection develops during the pulses and carries part of the energy, we find weaker pulses. This leads to lower amounts of mass being ejected and thus higher final BH masses of up to $\sim$\,$5\,M_\odot$. The differences are much smaller for the progenitors which determine the maximum mass of BHs below the gap. This prediction is robust at $M_{\rm BH, max}\simeq 48\,M_\odot$, at least within the idealized context of this study. This is an encouraging indication that current models are robust enough for comparison with the present-day gravitational-wave detections. However, the large differences between individual models emphasize the importance of improving the treatment of convection in stellar models, especially in the light of the data anticipated from the third generation of gravitational wave detectors.

description: Fiberboids are active filaments trapped at the interface of two phases, able of harnessing energy (and matter) fluxes across the interface in order to produce a rolling-like self-propulsion. We discuss several table-top examples and develop the physical framework for understanding their complex dynamics. In spite of some specific features in the examples studied we conclude that the phenomenon of fiberboids is highly generic and robust across different materials, types of fluxes and timescales. Fiberboid motility should play a role from the macroscopic realm down to the micro scale and, as recently hypothesized, possibly as a means of biological self-propulsion that has escaped previous attention.

description: This article concentrates on the optimal replacement of seedling tea by higher yielding clonal varieties. A hypothetical 500ha tea estate under seedling tea is used for this purpose. Representative yields, revenues, costs and replacement data with respect to the hypothetical 500ha tea estate are discussed first. This is followed by a gross margin analysis. However, as this produces only partial answers which may be misleading, a whole farm approach to the replacement problem is subsequently taken. Dynamic linear programming is used to derive economically optimal replacement strategies over a 30 year planning horizon, given certain yield and price scenarios. Some conclusions are also drawn.

description: The Riemann problem is one of the basic building blocks for numerical methods in computational fluid mechanics. Nonetheless, there are still open questions and gaps in theory and modeling for situations with complex thermodynamic behavior. In this series, we compare numerical solutions of the macroscopic flow equations with molecular dynamics simulation data. To enable molecular dynamics for sufficiently large scales in time and space, we selected the truncated and shifted Lennard-Jones potential, for which also highly accurate equations of state are available. A comparison of a two-phase Riemann problem is shown, which involves a liquid and a vapor phase, with an undergoing phase transition. The loss of hyperbolicity allows for the occurrence of anomalous wave structures. We successfully compare the molecular dynamics data with two macroscopic numerical solutions obtained by either assuming local phase equilibrium or by imposing a kinetic relation and allowing for metastable states.
