description: The aim of this study is to analyse the impact of agricultural output on economic growth in West Africa using the case of Benin. Time series data covering the period of 1961 to 2014 were used. The data were analysed through a Vector Error Correction Model (VECM). The results reveal that there is a long run, or equilibrium, relationship between agricultural output, industrial output, capital and GDP. The error correction model indicates that 21.6 percent of the discrepancy between long run and short run GDP is corrected within a year. The variance decomposition shows that the largest contribution to shocks in GDP is its feedback shocks. The contribution of agricultural output to shocks in GDP is less than 2% for the first three year period and about 6% for the ten year period. Capital contribution to shocks in GDP is about 3% for the first three years and more than 15% for the ten year period. Hence, apart from feedback and capital shocks, GDP is most influenced by agricultural output. Therefore, capital formation is primordial to economic growth in Benin but the economic activity upon which capital should be primarily invested is agricultural production.

description: Axioms for nonunital spectral triples, extending those introduced in the unital case by Connes, are proposed. As a guide, and for the sake of their importance in noncommutative quantum field theory, the spaces $\R^{2N}$ endowed with Moyal products are intensively investigated. Some physical applications, such as the construction of noncommutative Wick monomials and the computation of the Connes--Lott functional action, are given for these noncommutative hyperplanes.

Parent socialization of adolescent rumination
Creators: name: Goldman, Jennifer Lynn
Publisher: name: American University
Year: 2023

description: This study investigated relationships between parent emotion socialization and ruminative responding to sad or depressed affect among a community sample of 205 male and female adolescents at variable risk for psychopathology. This was a cross-sectional study that utilized questionnaire and structured interview data obtained from adolescents and their parents. Rumination was conceived as a maladaptive cognitive style for regulating sadness that has been associated with increased duration, severity, and risk of depression. The Response Styles Questionnaire (RSQ; Nolen-Hoeksema & Morrow, 1991) assessed frequency of rumination. Gender differences in rumination and relationships between adolescent rumination and depression were examined. Consistent with predictions, females reported more rumination than males, and adolescent rumination and depressive symptoms were positively related. Parent socialization of adolescent rumination was also investigated in this study. Parent modeling of ruminative styles was proposed to socialize adolescents' response styles. However, hypotheses predicting similarities in parent-adolescent rumination, particularly among same-sex dyads and in cases where parents were highly ruminative and more depressed, were not supported. Parental responses to children's expressed sadness were also proposed to socialize adolescents' ruminative response styles. Planned and exploratory analyses examined whether parent socialization practices (supportive, unsupportive, magnifying) perceived by adolescents as contingent upon their sadness displays during childhood related to adolescent rumination. Gender differences in adolescent-reported parent practices and the relative contributions of maternal and paternal practices to adolescent rumination were also explored. Unsupportive parent socialization practices and father's magnifying practices were associated with higher adolescent rumination. Adolescent girls, relative to boys, reported greater frequency of paternal supportive socialization in response to their expressed sadness. Generally, female adolescents reported more rumination than males across type, frequency, and agent of parent socialization practice. Parents' unsupportive and magnifying practices predicted adolescent rumination once adolescent sex was controlled, and parents' unsupportive and fathers' magnifying socialization explained variance in adolescent rumination beyond that of other practices. These results suggest that adolescent females, and adolescents of either sex who perceive their parents to have been punitive/neglectful or to have become sad/distressed in response to their sadness displays, may be particularly vulnerable to rumination. Prevention and treatment implications are discussed.

description: This paper conducted cross-sectional and panel census data analysis from year 2005 and 2010 in addition to factor share analysis to consider the regional differences that impact farmland consolidation in three areas of Japan, namely Tohoku, Hokuriku, and Kinki. First, the characteristics of each area indicated differential influences on the performance of the land consolidation policy. Second, organized farm management bodies such as village-based farming organization approved by the government also had positive impacts on farmland consolidation. The results of factor share analysis indicated three points. First, the effect of the number of Non-farmer with farmland ownerships had highest share in all areas. Second, the impacts of regionally differential characteristics on farmland consolidation had individual characteristic effects of municipality and time effect such as Kinki has high contribution rate of farm-work contract farming management body in panel data than cross-sectional data. Third, the factors that characterized the problem of each area showed higher effect on farmland consolidation. The government needs to consider regional differences when making decisions on farmland consolidation policies. . Acknowledgement :

description: With the growing concern for issues related to climate change, the development of sustainable agricultural value chains is of prime concern. Using a Discrete Choice Experiment, we examine both firms and farmers prospective responses to the internalization of sustainability through contract farming in the Vietnamese rice sector. Our findings suggest that farmers are more willing to internalize environmental sustainable production standards in contract farming than agribusiness firms. The latter are found less likely to mandate GlobalGAP/VietGAP production standards due to the cost of implementation and the lack of institutional support. It may be more interesting for firms to invest in standards with lower entry barrier. Furthermore, the internalization of the socio-economic pillar of sustainability in contract farming may require stimulating demand for sustainable rice and providing an enabling institutional environment for both farmers and firms to grasp new market opportunities.

description: The adoption of food standards to regulate product characteristics or its processing methods is widely widespread. Food economics literature has intensively explored the firm incentives for the adoption of safety and quality standards. A growing body of literature discusses on voluntary standards as alternative forms of governance of vertical relationships due to the increase of information transparency provided. There is a gap in the understanding of the determinants leading food firms to choose such alternative forms of transaction governance. The present study aims at exploring the significant drivers of voluntary standard adoption. To answer the questions we start from Transaction Cost Economic theory and we refer to an extended conceptual framework based on transaction risks, namely, risks arising from the opportunistic behaviour of economic agents (internal risks) and other risks related to unexpected changes in the economic environment (exogenous risks). Data was collected through interviews on an EU representative survey concerning the non-GMO voluntary standard in the soybean supply chain. The survey includes 363 companies from 15 EU countries. Preliminary results of the logit model suggest a positive relationship of transaction internal risks with the adoption of the voluntary non-GMO standard and a negative relationship of exogenous risks with the implementation of the standard.

description: We have obtained new optical imaging and spectroscopic observations of 78 galaxies in the fields of the rich clusters Abell 1413 (z = 0.14), Abell 2218 (z = 0.18) and Abell 2670 (z = 0.08). We have detected line emission from 25 cluster galaxies plus an additional six galaxies in the foreground and background, a much lower success rate than what was found (65%) for a sample of 52 lower-richness Abell clusters in the range 0.02 < z < 0.08. We have combined these data with our previous observations of Abell 2029 and Abell 2295 (both at z = 0.08), which yields a sample of 156 galaxies. We evaluate several parameters as a function of cluster environment: Tully-Fisher residuals, H-alpha equivalent width, and rotation curve asymmetry, shape and extent. Although H-alpha is more easily detectable in galaxies that are located further from the cluster cores, we fail to detect a correlation between H-alpha extent and galaxy location in those where it is detected, again in contrast with what is found in the clusters of lesser richness. We fail to detect any statistically significant trends for the other parameters in this study. The zero-point in the z~0.1 Tully-Fisher relation is marginally fainter (by 1.5 sigma) than that found in nearby clusters, but the scatter is essentially unchanged.

Combining this with a finite-volume analysis, we demonstrate that a lattice calculation of the easier computable connected correlation functions is able to provide valuable information of the noisier disconnected correlation functions, and may serve as a theory guidance for the future refinement of the corresponding lattice techniques.

X-ray time lags from a pivoting power law in black holes

description: Most black hole candidate X-ray binaries show Fourier time lags between softer and harder X-rays. The hard photons seem to arrive up to a few ms after the soft for a given Fourier frequency of the perturbation. The energy dependence of the time lags has a roughly logarithmic behavior. Up to now most theories fail to explain the observed magnitude and Fourier frequency dependence of the lags or fail other statistical tests. We show that the time lags can arise from a simple pivoting power law model, which creates the logarithmic dependence on the photon energy at once. A pivoting power law arises naturally from jet/synchrotron models for the X-ray emission, but may also be applicable to corona models. A hint to the coherence features of the light-curves can be obtained from the power spectral density, which can be decomposed into a few broad Lorentzians that could arise from a couple of strongly damped oscillators with low quality factors below one. Using small variations of the power law index for each Lorentzian separately the lags can be derived analytically. They show the correct Fourier frequency dependence of the time lags. If one assumes variations of the power law index by +- 0.2 the model can account for the observed magnitude of the time lags in Cyg X-1. As a further test we calculated the cross- and auto-correlation functions for our model, which also show qualitatively the observed behavior. The coherence function for the model is in agreement with the observed data in the Fourier regime, where the model is valid.

description: We report a simple protocol for the transition metal-free, visible-light-driven conversion of 1,3-diketones to tetra-substituted furan skeleton compounds in carbon dioxide (CO2) atmosphere under mild conditions. It was found that CO2 could be incorporated at the diketone enolic OH position, which was key to enabling the cleavage of a C–O bond during the rearrangement of a cyclopropane intermediate. This method allows for the same-pot construction of two isomers of the high-value tetra-substituted furan scaffold. The synthetic scope and preliminary mechanistic investigations are presented.

description: First-principles calculations within the weighted density approximation (WDA) were performed for ground state properties of ferroelectric perovskites PbTiO$_3$, BaTiO$_3$, SrTiO$_3$, KNbO$_3$ and KTaO$_3$. We used the plane-wave pseudopotential method, a pair distribution function $G$ based on the uniform electron gas, and shell partitioning. Comparing with the local density approximation (LDA) and the general gradient approximation (GGA), we found that the WDA significantly improves the equilibrium volume of these materials in cubic symmetry over both the LDA and GGA; Ferroelectric instabilities calculated by the WDA agree with the LDA and GGA very well; At the experimental ferroelectric lattice, optimized atom positions by the WDA are in good agreement with measured data; However the WDA overestimates the strain of tetragonal PbTiO$_3$ at experimental volume; The WDA overestimates the volume of fully relaxed structures, but the GGA results are even worse. Some calculations were also done with other models for $G$. It is found that a $G$ with longer range behavior yields improved relaxed structures. Possible avenues for improving the WDA are discussed.

title: Studies of light perception in marine diatoms and discovery of a novel blue light cryptochrome photoreceptor
Creators: name: Mangogna, Manuela
Publisher: name: The Open University
Year: 2007

description: The research project has focused on the structural and functional characterization of a gene denoted PtCPF1 (Cryptochrome/Photolyase Family 1) that encodes a putative photoreceptor in the diatom Phaeodactylum tricomutum. Cryptochromes (cry) are blue light receptors that share sequence similarity with photolyases, flavoproteins that catalyze the repair of UV light-damaged DNA.
 In order to characterize the diatom PtCPF1 gene, expression at both transcriptional and translational levels have been performed in time course experiments designed to study circadian rhythmicity and acute light induction responses. From this analysis PtCPF1 was shown to be strongly induced under blue light and to be expressed diurnally. In order to understand better the function of the gene product, the protein has been expressed and purified in E. coli. Spectral and biochemical analyses of the purified protein have shown that PtCPF1 is a blue-light-absorbing protein with DNA repair activity. On the other hand, localization studies in diatom cells have evidenced the constitutive nuclear localization of the protein.
 Interestingly, comparative analysis of the diatom PtCPF1 protein has revealed it to be more similar to the animal cryptochromes than to plant counterparts. Since animal crys act as components of the circadian clock controlling daily physiological and behavioural rhythms and as photoreceptors that mediate entrainment of the circadian clock to light, it was important to elucidate the function of the PtCPF1 protein both in a heterologous system and in an in vivo system. Remarkably, transcription assays developed in mammalian cells have evidenced a repressor activity of the PtCPF1 protein within the clock machinery, mimicking the function of animal crys. Furthermore, gene expression studies of transgenic diatom lines overexpressing PtCPF1 have indicated that the protein acts as a blue light photoreceptor because it can modulate several blue light-dependent responses.
 Therefore, this research project has identified a novel protein that displays both blue light photoreceptor activity as well as DNA repair activity. This protein could, in fact, be considered the missing link in the evolutionary history of the Cryptochrome/Photolyase family.
A New Derivation of the CPT and Spin-Statistics Theorems in Non-Commutative Field Theories

description: We propose an alternative axiomatic description for non-commutative field theories (NCFT) based on some ideas by Soloviev to nonlocal quantum fields. The local commutativity axiom is replaced by the weaker condition that the fields commute at sufficiently large spatial separations, called asymptotic commutativity, formulated in terms of the theory of analytic functionals. The question of a possible violation of the CPT and Spin-Statistics theorems caused by nonlocality of the commutation relations $[\hat{x}_μ,\hat{x}_ν]=iθ_{μν}$ is investigated. In spite of this inherent nonlocality, we show that the modification aforementioned is sufficient to ensure the validity of these theorems for NCFT. We restrict ourselves to the simplest model of a scalar field in the case of only space-space non-commutativity.

description: Soft Gamma Repeaters (SGRs) undergo changes in their pulse properties and persistent emission during episodes of intense burst activity. Both SGR 1900+14 and SGR 1806-20 have shown significant changes in their spin-down rates during the last several years, yet the bulk of this variability is not correlated with burst activity. SGR 1900+14 has undergone large changes in flux and a dramatic pulse profile change following burst activity in 1998. The flux level of SGR 1627$-$41 has been decreasing since its only recorded burst activity. Here, we review the global properties of SGRs as well as the observed dynamics of the pulsed and persistent emission properties of SGR 1900+14, SGR 1806-20 and SGR 1627-41 during and following burst active episodes and discuss what implications these results have for the burst emission mechanism, the magnetic field dynamics of magnetars, the nature of the torque variability, and SGRs in general.

description: In a context of extensive discussion about the occupation of agricultural areas in Brazil, the contribution of the present study is to analyze changes in use of land in the 558 Brazilian microregions from 1990-2016 as the objective of verifying agricultural activities that most won or lost area and identify the main factors that fueled the agricultural production of the country during the period. We analyzed 35 permanent and 33 temporary cultures using the Shift-share method, dividing the growth of each activity into five effects: yield, geographic location and area, the latter being subdivided into scale and substitution. The total harvested area grew 49.05%, from 50.5 to 75.3 million hectares. In the permanent activities there was 18.90% and temporary activities increased by 60.01%. Growth in the area of temporary crops was due to the expansion of agricultural frontier, as well as to the incorporation of previously occupied areas by permanent crops. The only two cultures, with positive substitution effects, were sugarcane and soybeans, which together were responsible for incorporating 96.14% of the entire area yielded by other activities. Coffee, orange, cassava, wheat, rice, beans, cotton and maize had a negative substitution effect, yielding 85.98% of area incorporated by other cultures. Acknowledgement :

description: In this paper we study the phase of self-similar solutions to general Nonlinear Schrödinger equations. From this analysis we gain insight on the dynamics of nontrivial solutions and a deeper understanding of the way collective coordinate methods work. We also find general evolution equations for the most relevant dynamical parameter $w(t)$ corresponding to the width of the solution. These equations are exact for self-similar solutions and provide a shortcut to find approximate evolution equations for the width of non-self-similar solutions similar to those of collective coordinate methods.

description: We study the formation of massive Population III binary stars using a newly developed radiation hydrodynamics code with the adaptive mesh refinement and adaptive ray-tracing methods. We follow the evolution of a typical primordial star-forming cloud obtained from a cosmological hydrodynamics simulation. Several protostars form as a result of disk fragmentation and grow in mass by the gas accretion, which is finally quenched by the radiation feedback from the protostars. Our code enables us, for the first time, to consider the feedback by both the ionizing and dissociating radiation from the multiple protostars, which is essential for self-consistently determining their final masses. At the final step of the simulation, we observe a very wide ($\gtrsim 10^4\,\mathrm{au}$) binary stellar system consisting of $60$ and $70\,M_\odot$ stars. One of the member stars also has two smaller mass ($10\,M_\odot$) companion stars orbiting at $200$ and $800\,\mathrm{au}$, making up a mini-triplet system. Our results suggest that massive binary or multiple systems are common among Population III stars.

description: This study investigated relationships between parent emotion socialization and ruminative responding to sad or depressed affect among a community sample of 205 male and female adolescents at variable risk for psychopathology. This was a cross-sectional study that utilized questionnaire and structured interview data obtained from adolescents and their parents. Rumination was conceived as a maladaptive cognitive style for regulating sadness that has been associated with increased duration, severity, and risk of depression. The Response Styles Questionnaire (RSQ; Nolen-Hoeksema & Morrow, 1991) assessed frequency of rumination. Gender differences in rumination and relationships between adolescent rumination and depression were examined. Consistent with predictions, females reported more rumination than males, and adolescent rumination and depressive symptoms were positively related. Parent socialization of adolescent rumination was also investigated in this study. Parent modeling of ruminative styles was proposed to socialize adolescents' response styles. However, hypotheses predicting similarities in parent-adolescent rumination, particularly among same-sex dyads and in cases where parents were highly ruminative and more depressed, were not supported. Parental responses to children's expressed sadness were also proposed to socialize adolescents' ruminative response styles. Planned and exploratory analyses examined whether parent socialization practices (supportive, unsupportive, magnifying) perceived by adolescents as contingent upon their sadness displays during childhood related to adolescent rumination. Gender differences in adolescent-reported parent practices and the relative contributions of maternal and paternal practices to adolescent rumination were also explored. Unsupportive parent socialization practices and father's magnifying practices were associated with higher adolescent rumination. Adolescent girls, relative to boys, reported greater frequency of paternal supportive socialization in response to their expressed sadness. Generally, female adolescents reported more rumination than males across type, frequency, and agent of parent socialization practice. Parents' unsupportive and magnifying practices predicted adolescent rumination once adolescent sex was controlled, and parents' unsupportive and fathers' magnifying socialization explained variance in adolescent rumination beyond that of other practices. These results suggest that adolescent females, and adolescents of either sex who perceive their parents to have been punitive/neglectful or to have become sad/distressed in response to their sadness displays, may be particularly vulnerable to rumination. Prevention and treatment implications are discussed.

description: This study examines the professional lives of a group of public high school teachers and a group of teachers working in a private, Pentecostal high school in order to comprehend exactly how neoliberal education reforms and the de-facto privatization of educational services in El Salvador are unfolding in the spaces of the local school. How, it asks, are high school teachers attempting to construct their professional lives just as the secondary education system is undergoing considerable transformation?; In addressing this question, the study compares teachers' daily life as it unfolds behind the classroom door, during staff meetings and in the teachers' lounge in two very different settings. Close examination of teachers' classroom practices recounts how teachers appropriate---according to their own personal histories---the new curricular forms and pedagogical ideals being introduced by education reform. The research explores the varied ideas that teachers bring from other social and historical contexts to their educative work and demonstrates how they actively engage particular aspects of national educational policy within the classroom. In this way, the study makes a case for seeing the classroom as a space wherein teachers still maintain a degree of occupational autonomy in the midst of changing and demanding working conditions. At the same time, the study demonstrates that teachers do not construct their professional lives exactly as they would have them. The conditions within which they work are shaped powerfully by the decisions of others and in ways that often contradict their own moral economies of work. The study describes how teachers draw on different class, religious and occupational histories and social relationships to engage the contradictions they confront at the local level. While this study demonstrates that education reform and the ongoing processes of privatization are circumscribing and problematizing teachers' contexts for deliberative social action, it offers an important reminder that teachers are not powerless in the face of change. The study calls for further critical exploration of how the commodification of educational activities worldwide are challenging teachers' efforts to improve their working conditions and to broaden their occupational autonomy beyond the four walls of the classroom.

description: We used treatment effect models to assess the effect of the women-centric community-based programme on intra-household decision making in agriculture. Using the data collected from an intra-household survey of 815 targeted and non-targeted households of a programme, we assessed the impact of women membership in a Self Help Group on dynamics of 14 farm and household related decisions by the primary decision maker and SHG member in the household. The study shows that though the role of women in decision making increased (8-10%), the effects vary according to the level of intervention and type of decision. Our results show that unlike micro-finance based SHGs, the conflicts were lesser in seed SHGs. Our study concludes that engagement of women in agriculture-based interventions could encourage joint decision making. Our finding suggests that development agencies engaged in interventions targeted to empower women should engage them in enterprising activities.

description: We propose an effective Hamiltonian approach to investigate decoherence of a quantum system in a non-Markovian reservoir, naturally imposing the complete positivity on the reduced dynamics of the system. The formalism is based on the notion of an effective reservoir, i.e., certain collective degrees of freedom in the reservoir that are responsible for the decoherence. As examples for completely positive decoherence, we present three typical decoherence processes for a qubit such as dephasing, depolarizing, and amplitude-damping. The effects of the non-Markovian decoherence are compared to the Markovian decoherence.

description: This paper examines the degree of mechanization in farm operations using household level data from four Indian states. It further explores the differential returns to farming and assesses the direct and indirect welfare distributional outcomes produced by mechanization. Findings suggest that the marginalized groups as defined in the study (those with limited factor endowments; those belonging to disadvantaged social groups and those who are subsistence oriented) exhibit lower levels of agricultural mechanization and earn substantially lower farm and off-farm incomes compared to others. The objective of the paper is to investigate how a technological change can generate major economic benefits but at the same time provoke adverse effects on the marginalized section of society. Decomposition of displaced labor as a result of mechanization shows that the displaced hired labor mainly belongs to the most vulnerable social groups of STs and SCs which forms the bulk of the rural labor force. The results demand undertaking development approaches that have the potential of bridging the productivity gaps promoting inclusive growth in the agriculture sector and to formulate strategies that can overcome the constraints faced by the marginalized farmers, thereby making farming more resilient and equitable.
