description: Background: Physical activity (PA) improves survival outcomes for several cancer sites, but few studies have examined the relationship with endometrial cancer (EC). Purpose: To evaluate associations between overall and disease-free survival with pre- and post-diagnosis PA by domain, intensity and dose (metabolic-equivalent task [MET]-hours/week/year). Methods: A prospective cohort study was conducted in Alberta of 425 women diagnosed with histologically-confirmed invasive EC between 2002-6 and followed to 2019. The interviewer-administered Lifetime Total Physical Activity Questionnaire recorded pre-diagnosis and post-diagnosis PA (~3.5 years after diagnosis). The association between PA and overall and disease-free survival was assessed with Cox-proportional hazard models adjusted for age, stage, grade, treatments, body mass index, menopausal status, hormone therapy use, family history, co-morbidities. Results: Median follow-up time was 14.5 years, during which 60 overall deaths and 80 EC recurrences/progressions or deaths occurred. Greater pre-diagnosis recreational PA was associated with improved disease-free survival (>14 vs ≤8 MET-hours/week/year; HR=0.54; 95% CI: 0.30-0.96; Ptrend=0.04) and overall survival (HR=0.56; 95% CI: 0.29-1.07; Ptrend=0.06). Post-diagnosis recreational PA was strongly associated with improved disease-free and overall survival (>13 vs ≤5 MET-hours/week/year; HR = 0.33, 95% CI: 0.17-0.64, Ptrend=0.001; HR = 0.33, 95% CI: 0.15-0.75, Ptrend=0.007). When participants maintained their recreational PA at the highest levels from pre- to post-diagnosis, they had high overall (HR = 0.43, 95% CI: 0.20-0.94) and disease-free survival (HR = 0.35, 95% CI: 0.18-0.69). Conclusions: Recreational PA may help to improve survival outcomes in EC survivors. Funding: Canadian Cancer Society Grants.

description: A study was conducted to study the effects of feed on survival and growth of local sarpunti (Puntius sarana) fry in nine glass aquaria (45 x 25 x 24 cm) for a period of 35 days in the Wet Laboratory of Fisheries Faculty, Bangladesh Agricultural University, Mymensingh. Each glass aquarium contained 10L of tap water and the stocking rate was 6L-1 of water. Three feeding treatments such as live feed (Plankton, 8,700/L), SABINCO feed containing 25% protein and formulated feed containing 30% protein were used for T1, T2 and T3, respectively. Each treatment had three replications. The growth performances in terms of length gain, weight gain and SGR (%/day) were 19.1±0.1 mm, 81.5±2.9 mg and 9.9±3.1 respectively in case of Ti and it was followed by T3 (10,9±0.1, 13.5±1.1 and 5.3±1.7, respectively) and T2 (7.8±0.4, 10.2±0.8 and 4.6±1.7, respectively). The highest survival rate was also found in Ti (77%) while the lowest in T2 (56.1%). Ti showed significantly (p<0.05) higher health condition (3.4±1.3) followed by T3 and T2 (1.3±0.1 and 1.2±2.1, respectively) but T2 and T3 did not differ significantly (p<0.05) from each other.

description: We investigate the potential of the galaxy power spectrum to constrain compensated isocurvature perturbations (CIPs), primordial fluctuations in the baryon density that are compensated by fluctuations in CDM density to ensure an unperturbed total matter density. We show that CIPs contribute to the galaxy overdensity at linear order, and if they are close to scale-invariant, their effects are nearly perfectly degenerate with the local PNG parameter $f_{\rm nl}$ if they correlate with the adiabatic perturbations. This degeneracy can however be broken by analyzing multiple galaxy samples with different bias parameters, or by taking CMB priors on $f_{\rm nl}$ into account. Parametrizing the amplitude of the CIP power spectrum as $P_{σσ} = A^2P_{\mathcal{R}\mathcal{R}}$ (where $P_{\mathcal{R}\mathcal{R}}$ is the adiabatic power spectrum) we find, for a number of fiducial galaxy samples in a simplified forecast setup, that constraints on $A$, relative to those on $f_{\rm nl}$, of order $σ_{A}/σ_{f_{\rm nl}} \approx 1-2$ are achievable for CIPs correlated with adiabatic perturbations, and $σ_{A}/σ_{f_{\rm nl}} \approx 5$ for the uncorrelated case. These values are independent of survey volume, and suggest that current galaxy data are already able to improve significantly on the tightest existing constraints on CIPs from the CMB. Future galaxy surveys that aim to achieve $σ_{f_{\rm nl}} \sim 1$ have the potential to place even stronger bounds on CIPs.

description: A 4-month feeding trial was conducted in ponds to evaluate the different diets for the culture of normal and monosex GIFT tilapia (Oreochromis niloticus). Twelve experimental ponds each of 80 m2 were divided into three treatments. Normal and monosex GIFT tilapia were assigned to each treatment in duplicate. Saudi Bangla tilapia feed, mixed feed and no feed but fertilization were considered as Ti, T2 and T3 respectively. The stocking density was 125 fingerlings/decimal. After four months of rearing Ti showed significantly (P<0.05) higher mean final weight of 148.25±2.73 g and 197.20±3.62 g for normal and monosex GIFT" tilapia respectively than those of T2 and T3. Among the treatments, Ti also resulted in significantly (P<0.05) higher specific growth rate than T2 and T3. However, there was no significant difference in survival rate and food conversion ratio between Ti and T2 but in case of T3 the survival rate was significantly (P<0.05) lower than Ti and T2. Again, the production of monosex GIFT tilapia was about 33% higher than that of normal GIFT tilapia. The net profit/ha generated from the 4 months culture period was calculated Tk. 67090.76, 38501.13 and 15906.8 for normal GIFT and Tk..121578.34, 75026.25 and 29396.08 for monosex GIFT in Ti, T2 and T3 respectively. The -results of the present study suggested that the culture of monosex GIFT tilapia is more profitable compared to normal GIFT tilapia and the use of Saudi Bangla tilapia feed is more economic than those of mixed feed and no feed but fertilization of the pond.

description: The present study focuses on studying the psychometric properties of Ethical Climate Questionnaire (ECQ) in Saudi educational milieu. It is a cross-sectional study and the data was collected from 309 educational supervisors from six educational offices of General Department of Education in Jeddah. Confirmatory Factor Analysis (CFA) was carried out to study the psychometric properties of the EC scale. Kuder Richardson's Cronbach's coefficient 'α’ was used to assess the reliability of the nine dimensions of the EC scale. Findings of the study revealed that nine dimensions of the EC scale had a good model fit. Hence, it is suggested that EC scale is valid and reliable for use within the educational context in Saudi Arabia. This study also compares the findings of the current study with previous findings. Results of the present study will provide much-needed impetus for future research in EC particularly, within the educational organizations throughout Saudi Arabia and generally in other Arab countries of the region.

description: Is there any entanglement in the simplest ubiquitous bound system? We study the solutions to the time-independent Schrödinger equation for a Hydrogenic system and devise two entanglement tests for free and localised states. For free Hydrogenic systems, we compute the Schmidt basis diagonalisation for general energy eigenstates, and for a Hydrogenic system localised to a three-dimensional Gaussian wavepacket, we demonstrate that measuring its second moments is sufficient for detecting entanglement. Our results apply to any system that exhibits Hydrogenic structure.

description: We describe a new approach to compute the electron-phonon self-energy and carrier mobilities in semiconductors. Our implementation does not require a localized basis set to interpolate the electron-phonon matrix elements, with the advantage that computations can be easily automated. Scattering potentials are interpolated on dense $\mathbf{q}$ meshes using Fourier transforms and ab initio models to describe the long-range potentials generated by dipoles and quadrupoles. To reduce significantly the computational cost, we take advantage of crystal symmetries and employ the linear tetrahedron method and double-grid integration schemes, in conjunction with filtering techniques in the Brillouin zone. We report results for the electron mobility in Si, GaAs, and GaP obtained with this new methodology.

description: The pion decay constants of the lowest orbitally excited states of the nucleon and the $Δ(1232)$ along with the corresponding axial transition form factors are calculated with Poincaré covariant constituent-quark models with instant, point and front forms of relativistic kinematics. The model wave functions are chosen such that the calculated electromagnetic and axial form factors of the nucleon represent the empirical values in all three forms of kinematics, when calculated with single-constituent currents. The pion decay widths calculated with the three forms of kinematics are smaller than the empirical values. Front and instant form kinematics provide a similar description, with a slight preference for front form, while the point form values are significantly smaller in the case of the lowest positive parity resonances.

description: Early investigators often saw a close relationship between "sleep" and "hypnosis." To many of them, it seemed that the only difference between the two "states" was that someone spoke to the subject during "hypnosis" while no one spoke to the subject during "sleep." However, none of these early investigators attempted a controlled experiment to compare the behavior of their subjects during "sleep" and "hypnosis." All relied simply on observation -- usually in a clinical setting.

description: Background: There is a lack of evidence on treatment of urinary tract infections (UTIs) in male patients in a primary care setting, and whether narrow-spectrum antibiotics are safe and effective. Objectives: To explore antibiotic switch rates after treatment with UTI antibiotics in men over the last 11 years. Material: We analysed data from the Norwegian Prescription Database (NorPD). Men ≥16 years receiving cefalexin, ciprofloxacin, cotrimoxazole, nitrofurantoin, ofloxacin, pivmecillinam or trimethoprim during the period 2008–2018 were included. Antibiotic switch was defined as being prescribed a different antibiotic drug appropriate for UTI within 14 days after initial treatment. We calculated rates of antibiotic switch and corresponding odds ratios for each antibiotic drug. Results: Seven hundred twenty-six thousand and ninety-six (726,096) prescriptions to 429,807 men were defined as possible UTI episodes. Fluoroquinolones, pivmecillinam and cotrimoxazole were most frequently prescribed. Forty-nine thousand five hundred and thirty-one (49,531) (6.8%) of the treatments resulted in antibiotic switch. Compared to cotrimoxazole, the risk of antibiotic switch was higher for pivmecillinam (OR: 2.46; 95% CI, 2.39–2.53) and trimethoprim (OR: 2.12; 95% CI, 2.04–2.20), and lower for fluoroquinolones (OR: 0.40; 95% CI, 0.39–0.42) and cefalexin (OR: 0.28; 95% CI, 0.26–0.30). Treatment duration of ≥7 days and age of ≥50 years were associated with an increased risk of antibiotic switch. Conclusion: Fluoroquinolones and cefalexin were associated with lower antibiotic switch rates than the recommended UTI antibiotics (pivmecillinam, nitrofurantoin and trimethoprim). However, the rates of antibiotic switch following treatment of male patients with first-line empirical UTI antibiotics are relatively low, indicating that the current guidelines are safe.

description: The effect of Richard T. Cox's contribution to probability theory was to generalize Boolean implication among logical statements to degrees of implication, which are manipulated using rules derived from consistency with Boolean algebra. These rules are known as the sum rule, the product rule and Bayes' Theorem, and the measure resulting from this generalization is probability. In this paper, I will describe how Cox's technique can be further generalized to include other algebras and hence other problems in science and mathematics. The result is a methodology that can be used to generalize an algebra to a calculus by relying on consistency with order theory to derive the laws of the calculus. My goals are to clear up the mysteries as to why the same basic structure found in probability theory appears in other contexts, to better understand the foundations of probability theory, and to extend these ideas to other areas by developing new mathematics and new physics. The relevance of this methodology will be demonstrated using examples from probability theory, number theory, geometry, information theory, and quantum mechanics.

description: We consider the singular behaviour of one-loop QCD matrix elements when several external partons become simultaneously parallel. We present a new factorization formula that describes the singular collinear behaviour directly in colour space. The collinear singularities are embodied in process-independent splitting matrices that depend on the momenta, flavours, spins and colours of the collinear partons. We give the general structure of the infrared and ultraviolet divergences of the one-loop splitting matrices. We also present explicit one-loop results for the triple collinear splitting, $q \to q {\bar Q} Q$, of a quark and a quark--antiquark pair of different flavours. The one-loop triple collinear splitting is one of the ingredients that can be used to compute the evolution of parton distributions at the next-to-next-to-leading order in QCD perturbation theory.

description: A study was conducted from January-May 2007 to know some biological aspects i.e. gonadosomatic index (GSI), gamete sizes (egg diameter and sperm-head length), fecundity, condition factor (CF), relationship of body weight-fecundity and ovary weight-fecundity of Thai koi Anabas testudineus. The highest gonadosomatic index (19.50 ± 0.54), ova diameter (654.10 ± 6.37 pm) and sperm head-length (3.18 ± 0.08 pm) were found in 17th April. The mean fecundity was estimated to be 5,53,708 ± 41,041/kg with a range between 1,13,285 and 10,25,423/kg. The ovary weight ranged from 2.86 to 20.50g/100g with a mean of 11.16 ± 0.696g/100g, whereas the average numbers of eggs/g body and ovary weight were 526 and 4480 respectively. The highest condition factor (CF) 1.005 ± 0.12 indicated good health condition of fish in April than in the other months. The regression analysis showed that the relationship between body weight-fecundity and ovary weight-fecundity were linear. Co-efficient of correlation (r) of ovary weight-fecundity was highly significant (P<0.01) and stronger than the correlation (r) of body weight-fecundity. From the results it can be concluded that the peak spawning period of Thai koi might be in April.

description: It is widely believed and in part established that exact global symmetries are inconsistent with quantum gravity. One then expects that approximate global symmetries can be quantitatively constrained by quantum gravity or swampland arguments. We provide such a bound for an important class of global symmetries: Those arising from a gauged $U(1)$ with the vector made massive via Higgsing with an axion. The latter necessarily couples to instantons, and their action can be constrained, using both the electric and magnetic version of the axionic weak gravity conjecture, in terms of the cutoff of the theory. As a result, instanton-induced symmetry breaking operators with a suppression factor not smaller than $\exp(-M_{\rm P}^2/Λ^2)$ are present, where $Λ$ is a cutoff of the 4d effective theory. We provide a general argument and clarify the meaning of $Λ$. Simple 4d and 5d models are presented to illustrate this, and we recall that this is the standard way in which things work out in string compactifications with brane instantons. The relation of our constraint to bounds that can be derived from wormholes or gravitational instantons and to those motivated by black-hole effects at finite temperature are discussed, and we present a generalization of the Giddings-Strominger wormhole solution to the case of a gauge-derived $U(1)$ global symmetry. Finally, we discuss potential loopholes to our arguments.

description: A field experiment was conducted at Bangladesh Agricultural University Farm, Mymensingh, during the Boro season 2006 to evaluate the response of transplanted Boro rice (BRRIdhan29) under different irrigation practices. Five irrigation treatments viz. 5 cm standing water was maintained throughout the growing season (Ti), 5 cm standing water was applied as soon as water disappeared from the field i.e. saturation was reached (T2), 5 cm standing water was applied 3 days after disappearing of standing water (T3), 5 cm standing water was applied 5 days after disappearing of standing water (T4) and 5 cm standing water was applied 7 days after disappearing of standing water (T5) were used. Each treatment was replicated thrice. Triple super phosphate (TSP) and muriate of potash (MP) fertilizers were applied before transplanting at the rate of 77 kg/ha and 59 kg/ha, respectively and urea fertilizer was applied thrice, namely, before transplanting, 20 days after transplanting (DAT) and 35 DAT equally in all treatment plots at the rate of 304 kg/ha. BRRIdhan29 was transplanted on 3 February and harvested on 27 May 2006. Irrigation treatments showed significant effects on the yield and—yield contributing characters of Boro rice (BRRIdhan29). The results showed that the highest grain yield of 9.56 t/ha was obtained in treatment T2 followed by T1 (9.51 t/ha) and T5 gave the lowest grain yield of 7.06 t/ha. It was also found that the reduction in grain yield in T3 was 1.79% in comparison to treatment T1, whereas, the water productivity was increased by 25% more than that of Ti. The application of irrigation water 3 days after disappearing of standinvNater (T3) together with T4 and T5 will considerably save the water but reduced the grain yield significantly. Therefore, from the experimental findings, it may be inferred that 5 cm standing water applied 3 days after disappearing of standing water (T3) produced the satisfactory yield for BRRIdhan29.

description: We report on an X-ray observation of the Seyfert 1.5 galaxy Mrk 6 obtained with the EPIC instruments onboard XMM-Newton. Archival BeppoSAX PDS data from 18-120 keV were also used to constrain the underlying hard power-law continuum. The results from our spectral analyses generally favor a double partial-covering model, although other spectral models such as absorption by a mixture of partially ionized and neutral gas cannot be firmly ruled out. Our best-fitting model consists of a power law with a photon index of 1.81+/-0.20 and partial covering with large column densities up to 10^{23} cm**-2. We also detect a narrow emission line consistent with Fe Kalpha fluorescence at 6.45+/-0.04 keV with an equivalent width of ~93+/-25 eV. Joint analyses of XMM-Newton, ASCA, and BeppoSAX data further provide evidence for both spectral variability (a factor of ~2 change in absorbing column) and absorption-corrected flux variations (by ~60%) during the ~4 year period probed by the observations.

description: For each compact almost Kahler manifold $(X,\om,J)$ and an element A of $H_2(X;Z)$, we describe a closed subspace $\ov{\frak M}_{1,k}^0(X,A;J)$ of the moduli space $\ov{\frak M}_{1,k}(X,A;J)$ of stable J-holomorphic genus-one maps such that $\ov{\frak M}_{1,k}^0(X,A;J)$ contains all stable maps with smooth domains. If $(P^n,\om,J_0)$ is the standard complex projective space, $\ov{\frak M}_{1,k}^0(P^n,A;J_0)$ is an irreducible component of $\ov{\frak M}_{1,k}(P^n,A;J_0)$. We also show that if an almost complex structure $J$ on $P^n$ is sufficiently close to J_0, the structure of the space $\ov{\frak M}_{1,k}^0(P^n,A;J)$ is similar to that of $\ov{\frak M}_{1,k}^0(P^n,A;J_0)$. This paper's compactness and structure theorems lead to new invariants for some symplectic manifolds, which are generalized to arbitrary symplectic manifolds in a separate paper. Relatedly, the smaller moduli space $\ov\M_{1,k}^0(X,A;J)$ is useful for computing the genus-one Gromov-Witten invariants, which arise from the larger moduli space $\ov\M_{1,k}(X,A;J)$.

description: By restricting to a class of localic open groupoids $G$ which, similarly to Lie groupoids, possess appropriate covers $\widehat G\to G$ by étale groupoids, we extend results about groupoid actions and quantales that were previously proved for étale groupoids but do not seem to work for arbitrary open groupoids. In particular we obtain a characterization of the category of $G$-actions as a category of quantale modules on $\mathcal O(\widehat G)$ that satisfy a condition related to the quantale $\mathcal O(G)$. This leads to a simple description of $G$-sheaves and the classifying topos of $G$ in terms of Hilbert $\mathcal O(\widehat G)$-modules. The bicategory whose 1-cells are the groupoid bi-actions is bi-equivalent to a corresponding bicategory of quantales and bimodules.

description: Early investigators often saw a close relationship between "sleep" and "hypnosis." To many of them, it seemed that the only difference between the two "states" was that someone spoke to the subject during "hypnosis" while no one spoke to the subject during "sleep." However, none of these early investigators attempted a controlled experiment to compare the behavior of their subjects during "sleep" and "hypnosis." All relied simply on observation -- usually in a clinical setting.

description: The study is concerned with the kinetics of osmotic dehydration and development of jam from hogplum. Dehydration process was performed using sucrose and sodium chloride as osmotic agents. The study showed that the rate and extent of water loss, moisture content, solid gain and normalized solid content (NSC) were strongly influenced by concentration of osmotic solution and immersion time. Among the different solution concentration of sucrose and/oF salt, 55/10% sucrose/salt solution gave the highest NSC (4.11) for 6 hours contact time, while 60% sucrose solution also gave an NSC value of 3.36 for similar contact time. Two equations were developed using Fick's diffusion equation from which the value of mass transfer co-efficients were calculated and found to be 0.1263 Mir1-112 and 0.1616 min-1/2 for 60% sucrose and 55/10% sucrose/salt solution respectively. Organoleptic taste testing using 1-9 hedonic scale showed that all the developed jams (from different hogplum samples) were acceptable by the panelists. Jam from 55/10% sucrose/salt osmosed solution was ranked as 'Like very much' and that from mechanically dried hogplum slices was ranked as 'like moderately' while jam from fresh hogplum was adjudged 'Like slightly'.

description: Background: The link between physical activity (PA) and cognitive function, behaviour, academic achievement and wellbeing in children is strong. Data, however, suggests that children and young people do not meet PA guidelines. Purpose: To gain a school’s perspective on the implications and utility of a whole-school approach to physical activity in a primary school setting. Methods: The PESSPA (Physical Education, School Sport, Physical Activity) toolkit was designed by primary school professionals and researchers to demonstrate the importance and best practice for PESSPA. A qualitative design (interviews) was utilised with primary school staff to understand the school PA culture and initial impressions of a whole-scool approach to PA, PESSPA toolkit. Data were analysed thematically. Participants (N = 13) were primary school PE leads (n = 10) and senior leadership team members (n = 3). Interviews utilised face-to-face and telephone methods, followed a semi-structured interview schedule, and averaged 41.76minutes in length. Results: Analysis revealed that schools saw the importance of an active school, highlighted both facilitators and barriers to supporting child PA, and evaluated the PESSPA toolkit positively. Overarching themes and implications of a whole-school approach to PA will be discussed. Conclusions: The PESSPA toolkit was well received by primary school staff, highlighting the utility of a whole-school approach to support a positive PA structure at school. The next stage of the project includes investigation of the long-term tool impact on primary school PESSPA provision. Funding: Local funding: National Centre for Sport and Exercise Medicine.

description: An experimental investigation was carried out to study the flexural strength and punching shear resistance of some selected ferrocement slab elements. Ferrocement slabs were made with expanded metal mesh having three different thicknesses of 15 mm, 20 mm and 25 mm. For each thickness the number of mesh layer varied from one to three. The dimensions of the specimens were selected as 300x100x15 mm, 300x100x20 mm and 300x100x25 mm for flexural strength, and 300x300x15 mm, 300x300x20 mm and 300x300x25 mm for punching shear resistance. Cement mortar having cement, sand and water ratios of 1: 2 : 0.5 was used for casting the slabs. After 28 days of water curing, the specimens were tested for flexural strength and punching shear resistance. It has been found that with the increase in the number of layers the flexural strength increased. Among the selected slabs, the 15 mm thickness slabs with three layers of wire mesh exhibited the highest load bearing capacity in flexure. Similarly, the increase in the number of wire mesh layers resulted in an improvement in resisting the cracking load and the ultimate punching load of ferrocement slabs.

description: We include the treatment of quadrupolar fields beyond the Fröhlich interaction in the first-principles electron-phonon vertex in semiconductors. Such quadrupolar fields induce long-range interactions that have to be taken into account for accurate physical results. We apply our formalism to Si (nonpolar), GaAs, and GaP (polar) and demonstrate that electron mobilities show large errors if dynamical quadrupoles are not properly treated.

description: We present resonant ultrasound elastic constant measurements of the clathrate compounds Eu8Ga16Ge30 and Sr8Ga16Ge30. The elastic response of the Eu clathrate provides clear evidence for the existence of a new type of four-well tunneling states, described by two nearly degenerate four level systems (FLS). The FLS's are closely linked with the fourfold split positions of Eu known from neutron diffraction density profiles. Using a realistic potential we estimate the tunneling frequencies and show that the energy gap between the two FLS's is of the same order as the Einstein oscillator frequency. This explains why the observed harmonic oscillator type specific heat is not modified by tunneling states. In addition the quadrupolar interaction of FLS's with elastic strains explains the pronounced depression observed in elastic constant measurements. In the case of the Sr clathrate, we show that the shallow dip in the elastic constant c44 is explained using the same type of quadrupolar interaction with a soft Einstein mode instead of a FLS.

description: Corner solution problems are pervasive in micro-econometric acreage choice models because farmers rarely produce the same crop set in a considered sample. These crop choice problems raise significant modelling issues. The main aim of this paper is to propose an endogenous regime switching model specifically designed for empirically modeling acreage choices with corner solutions. Contrary to models based on censored regression systems that have been used until now, this model is fully coherent from a micro-economic point of view. It also includes regime fixed costs accounting for unobserved costs which only depend on the set of crops grown simultaneously. We illustrate the empirical tractability of this model by estimating an endogenous regime switching multi-crop model for a panel dataset of French farmers. The estimated model considers yield supply, input demand and acreage share models for 7 crops and considers 8 production regimes. It also accounts for unobserved heterogeneity in farmers behaviors through the specification of random parameters. We assume that most model parameters are farmer specific and estimate their distribution across the farmers population represented by our sample. Our results show that farmers production acreage choice mechanisms strongly depend on the production regime in which this choice takes place. Acknowledgement :

description: Rural e-commerce has developed rapidly in China, but it has presented big regional differences. This paper aims to empirically examine what determines the development of rural e-commerce in China. It is further hoped to contribute to reduce the gap of regional differences in e-commerce development and prompt the e-commerce development in underdeveloped areas. The emerging and rapid growth of Taobao Villages is a typical example of rural e-commerce development. We therefore focus on exploring the major driving forces of emerging Taobao Villages in China. The data used in this study are generated through Geography Information System with location of each Taobao Village and data mining with web crawler, which includes the data for a total sample of 2018 Taobao Villages over 2013-2017. The random-effect probit and bivariate probit models with robust standard errors and clustering standard errors are estimated. The results show that the economic condition of a village and its surrounding areas and the distances to national way and highway impact the development of rural e-commerce at different extents. The area with developed e-commerce promotes rural e-commerce development of the nearby areas, which reflects there are spillover effects on developing rural e-commerce. The paper concludes with several policy implications. Acknowledgement : Funding for this research was supported by a grant from the Asian Development Bank (2017X127.CCA).

description: For early symbolic communicators, acquisition of an initial vocabulary is a critically important achievement that sets the stage for future language development. Children who require augmentative and alternative communication (AAC) rely on others to select and provide these important first words for them. One resource to help guide this process includes published lists of words that may contribute to a core vocabulary for individuals who require AAC. Although some clinicians report that they consider or prioritize core words during the vocabulary selection process, it is not known whether an emphasis on core words will best meet the expressive vocabulary needs of early symbolic communicators. The purposes of this narrative review were to (a) review studies that have developed word lists to inform selection of a core vocabulary for young children who require AAC, (b) compare the words on these lists to the early words used by children with typical development, and (c) consider the implications for vocabulary selection and language development for early symbolic communicators who require AAC. Results suggest that core word lists may under-emphasize many of the types of words that predominate in early expressive vocabulary; these lists may not be the most appropriate resources to guide AAC system design and instruction for early symbolic communicators.
