description: Background: Obesity and its co-morbidities account for a large proportion of chronic disease in the U.S. In an effort to reduce rates of obesity among children, YMCA of the USA (Y-USA) has developed a program called Healthy Weight and Your Child (HWYC), a multi-session intervention program for children carrying excess weight aged 7-13 years old delivered through local YMCAs. To date, 19 local YMCAs have successfully delivered pilot versions of the program. As Y-USA moves from the validation stage of HWYC to translating and scaling the program, Y-USA hopes to improve the model by identifying factors in program delivery that best lead to successful delivery of the program. This analysis used classification and regression tree (CART) modeling to identify such explanatory factors that predict successful delivery of HWYC in local YMCAs, as measured by Change in child BMI and % Attendance.Methods: Participants in HWYC pilot programs included children with obesity (BMI > 95th percentile for age and gender) (n = 782). Data collection included baseline and session 20 weight, height, and waist circumference measures, as well as demographic information. Attendance was measured at every program session. Bivariate and CART analysis was performed in R using previously collected and de-identified data.Results: CART analysis found that a participants attendance is most predicted by the YMCA site delivering HWYC, as well as demographic factors such as race and eligibility for free/reduced lunch. The baseline BMI of the accompanying adult also influenced attendance. CART also found that class size was a major predictor of change in childs BMI, as were program model (yearlong vs. condensed) and sex.Conclusions: The CART analysis successfully identified several factors 40 that predict both attendance and childs BMI change among participants in the HWYC program. Results suggest that Y-USA should scale HWYC to more YMCAs using the condensed 4-month program model to achieve greater successful outcomes. Additionally, individual YMCAs may need to consider the demographics of their unique communities in order to improve both attendance and BMI reduction. As the sample size of the condensed program was small (n = 120), future studies are required to better understand unique explanatory factors that predict successful delivery of HWYC under this program model.

description: We describe a technique that for the first time measures star formation rates (SFRs) in damped Lyman alpha systems(DLAs) directly. We assume that massive stars form in DLAs, and that the FUV radiation they emit heats the gas by the grain photoelectric mechanism. We infer the heating rate from the cooling rate measured by the strength of CII* 1335.7 absorption. Since the heating rate is proportional to the dust-to-gas ratio and the SFR per unit area, we deduce the SFR per unit area for DLAs in which both quantities have been measured. We consider models in which the the dust comprises carbonaceous or silicate grains. We present two-phase models where the cold neutral medium (CNM) and warm neutral medium (WNM) are in pressuer equilibrium. In the CNM model the the sightline goes throught the CNM and WNM, while in the WNM model it goes only through the WNM. Since the grain photoelectric heating efficiency is at least 10 times higher in the CNM than in the WNM, CII* absorption mainly arises in the CNM in the CNM model. But in the WNM model all of the CII* absorption arises in the WNM. We use CII* absorption lines to derive the SFR per unit area for a sample of ~ 30 DLAs in which the dust-to-gas ratio has been inferred from element depletion patterns. We show that the resulting SFR per unit area corresponds to an average over the star forming volume of galaxy hosting the DLA rather than to local star formation along the line of sight. We find the average SFR per unit area and equals10$^{-2.2}$ M$_{\odot}$yr$^{-1}$kpc$^{-2}$ for the CNM model and 10$^{-1.3}$ M$_{\odot}$yr$^{-1}$kpc$^{-2}$ for the WNM model. The SFR per unit area in the CNM solution is similar to that measured in the Milky Way ISM.

description: This case study deals with The Dow Chemical Company’s (Dow) decision on how to restore a greenbelt area with historical issue that borders a brownfield property owned by the city of Midland, Michigan. Dow has a stated goal to apply a “business-decision process that values nature” and to deliver $1 billion in “value through projects that are good for business and good for ecosystems.” In line with this goal, Dow wanted to restore the greenbelt area by enhancing habitat and ecosystem services to Dow and Midland in a way that was also beneficial to the company’s bottom line. This case study presents three alternative restoration designs along with detailed financial cost and environmental data for each design. Students perform cost-benefit analysis, highlighting potential differences between how costs are calculated in a public setting relative to a private setting. In addition, students assess how the inclusion of important non-financial environmental data may be used to inform decision making.

description: Given a finite set $X$ and a function $f:X\to X$, we define the degree of noninvertibility of $f$ to be $\displaystyle\text{deg}(f)=\frac{1}{|X|}\sum_{x\in X}|f^{-1}(f(x))|$. This is a natural measure of how far the function $f$ is from being bijective. We compute the degrees of noninvertibility of some specific discrete dynamical systems, including the Carolina solitaire map, iterates of the bubble sort map acting on permutations, bubble sort acting on multiset permutations, and a map that we call "nibble sort." We also obtain estimates for the degrees of noninvertibility of West's stack-sorting map and the Bulgarian solitaire map. We then turn our attention to arbitrary functions and their iterates. In order to compare the degree of noninvertibility of an arbitrary function $f:X\to X$ with that of its iterate $f^k$, we prove that \[\max_{\substack{f:X\to X\\ |X|=n}}\frac{\text{deg}(f^k)}{\text{deg}(f)^γ}=Θ(n^{1-1/2^{k-1}})\] for every real number $γ\geq 2-1/2^{k-1}$. We end with several conjectures and open problems.

description: The term “wicked problems” is not well recognized in the field of applied economics. Normally used to describe situations or scenarios that are difficult to solve using standard modeling methods, these problems are often highly complex and span multiple disciplines. As a result, traditional methods for teaching economists how to problemsolve may not suffice. In this paper, we assess whether or not the case study method is an possible strategy to better equip students to deal with, account for, and solve wicked policy problems in applied economics. We focus on a single, but highly timely and relevant wicked-type policy problem: “Whether or not to change the designation and/or size of the Bear’s Ears National Monument in Utah.” The Bears Ears issue has all the hallmarks of a wicked-type problem. There are many sides to the issue and thus many diverse key stakeholders involved. To address this issue we ask students in an advanced applied economics course to role-play as members of a private a consulting firm hired to and to determine the “socially optimal” size of the Bears Ears National Monument, using economics criteria discussed throughout the semester. Based on their results, students are asked to offer policy recommendations and explain in detail the limitations of their results. We assess student learning outcomes using a pre- and post-survey, a take-home assignment, and an in-class group presentation. To discourage the free-rider problem, we assess individual contributions by having students complete individual evaluations.

description: There is signiﬁcant interest in the use of market mechanisms for controlling nutrient pollution, one of the most challenging threats to water quality in the United States and elsewhere. This type of pollution often is characterized by considerable lag times between discharge from the pollution source and delivery to the impaired waters. We investigate the implications of these lags for eﬃcient pollution reduction markets and compare two alternative market designs: 1) forward markets where participants trade pollution deliveries directly and 2) a trading ratio system where they trade contemporaneous discharges. While a system of ﬁrst-best trade ratios is complex in early periods, this system can produce the optimal steady state loads using a simple trading rule. We also ﬁnd that while ﬁrst-best trade ratios are greater than one when there are lag disparities between trading partners, second-best trade ratios under the same lag disparities may be less than one when the overall cap on discharges is set suﬃciently small.

We describe an inspiral search code and results from hardware injection tests and demonstrate that injected signals can be recovered by the data analysis pipeline. The parameters of the recovered signals match those of the injected signals.

description: Credit stacking involves the sale of multiple types of environmental credits from a single, spatially defined project. The practice is controversial because environmental advocates suspect (a) producers may undermine the principle of additionality by extracting unearned profits through the sale of by-products from actions taken based on the incentives for a single credit-type, (b) society may lose the opportunity for free environmental improvements when complementary or joint production creates such by-products, or (c) broader environmental quality may decline by allowing polluters’ cheaper or easier compliance with off-set requirements, weakening incentives to avoid initiating degradation. Previous research ignores producers’ potential responses when the credit stacking policy changes. This paper offers a framework to analyze the interaction between credit stacking policy and producers’ choices—especially regarding their choice of production technology—and the implications for the relative advantages of alternative stacking policies for environmental markets.

description: Hate-speech detection on social network language has become one of the main researching fields recently due to the spreading of social networks like Facebook and Twitter. In Vietnam, the threat of offensive and harassment cause bad impacts for online user. The VLSP - Shared task about Hate Speech Detection on social networks showed many proposed approaches for detecting whatever comment is clean or not. However, this problem still needs further researching. Consequently, we compare traditional machine learning and deep learning on a large dataset about the user's comments on social network in Vietnamese and find out what is the advantage and disadvantage of each model by comparing their accuracy on F1-score, then we pick two models in which has highest accuracy in traditional machine learning models and deep neural models respectively. Next, we compare these two models capable of predicting the right label by referencing their confusion matrices and considering the advantages and disadvantages of each model. Finally, from the comparison result, we propose our ensemble method that concentrates the abilities of traditional methods and deep learning methods.

description: We consider the minimal supersymmetric SO(10) model, where only one {\bf 10} and one $\bar{\bf 126}$ Higgs multiplets have Yukawa couplings with matter multiplets. This model has the high predictive power for the Yukawa coupling matrices consistent with the experimental data of the charged fermion mass matrices, and all the Yukawa coupling matrices are completely determined once a few parameters in the model are fixed. This feature is essential for definite predictions to the proton decay rate through the dimension five operators. We analyze the proton decay rate for the dominant decay modes $p \to K^{+} \barν$ by including as many free parameters as possible and varying them. There are two free parameters in the Yukawa sector, while five in the Higgsino sector. It is found that an allowed region exists when the free parameters in the Higgs sector are tuned so as to cancel the proton decay amplitude. The resultant proton lifetime is proportional to $1/\tan^2 β$ and the allowed region eventually disappears as $\tan β$ becomes large.

description: Food waste represents an inefficiency along the supply chain that can hamper food system productivity. As countries align national targets with the United Nations’ Sustainable Development Goal to halve per capita food waste at the retail and consumer, addressing consumer food waste is regarded as one of the key channels to achieve these goals in developed countries. Acquisition of knowledge, such as organizational learning-by-doing, has been shown to be a significant source of productivity growth in a variety of industries. This paper investigates the role of incidental learning in reducing consumer plate waste during all eating occasions over approximately one week based on a unique data source with food-item level data collected from 50 adults from the United States using the Remote Food Photography Method.® Aligning with existing literature, we find subject behavior is consistent with significant incidental learning. As observed plate waste experience accumulates, subjects accomplished significant plate waste reduction by cleaning their plates, which also increased calorie intake. No evidence is found that learning from the past alters the amount of food that subjects’ select. Given that habitual plate cleaning has been associated with overweight and obesity, social welfare maximizing public policy interventions should consider explicit information to help consumers switch the focus from the intentions not to waste (i.e., minimize food waste by cleaning plate after food was over-selected) to improvements in the ability to reduce food waste (i.e., selecting an appropriate amount of food).

The Dual Role of Convergent Natural Selection and Evolutionary History in the Morphology of Gammarus minus Populations
Creators: name: Popa, Radu
Publisher: name: American University
Year: 2023

description: An important subject of study in the field of evolutionary· biology is the relationship between phylogeny and adaptation. Many researchers are involved in studies regarding the evolutionary significance of different phenotypic patterns. In environments where strong ( and similar) selective pressures exist many characters display convergence. The similarities between populations from geographically distant but environmentally similar milieu can mislead phylogenetic considerations. This is why the identification and elimination of characters affected by convergent evolution is important before any understanding of evolutionary history is possible. Four Grammarus minus populations from West Virginia were studied. Two populations were cave inhabitants and two populations were spring inhabitants. Each spring population selected was phylogenetically related to a cave population from the same hydrologic basin. However, since both cave and spring environments offer very specific environmental conditions it was expected that many characters to display convergence between populations living in different hydrologic basins. The phylogenetic (basin) effect was surveyed based on characters that display differences between basins while the convergence was surveyed based on resemblances between populations living in similar habitats. Identification of characters displaying convergence only and phylogeny only was also done.Measurements were done on 46 characters, mostly appendages. Since a consistent difference in size exists between cave and spring organisms, a correction for size was done so that the observed differences represented shape differences.The results show that significant differences exist between the investigated populations. Many differences also exist between sexes. Most characters display a habitat effect and only a few show basin effects. After all ch8.1:acters showing habitat x basin interactions were eliminated, eleven characters ( out of 46) show convergence (habitat effect), and only four characters (out of 46) show phylogeny (basin effect). Seven characters shoved convergence only and none showed phylogeny only. Only one character displayed interaction between sex and habitat and non showed interaction between basin and sex. Many characters, ( 12 for males and 34 for females, out of 46), show interaction between habitat and basin suggesting the possible significance of such interactions in adaptation.

description: Fuelwood collection is often cited as the most important cause of deforestation in developing countries. Use of fuelwood in cooking is a leading cause of indoor air pollution. Using household data from India, we show that households located farther away from the forest spend more time collecting. Distant households are likely to sell more fuelwood and buy less. That is, lower access to forests increases fuelwood collection and sale. This counter-intuitive behavior is triggered by two factors: lower access to forests (a) increases the fixed costs of collecting, which in turn leads to more collection; and (b) drives up local fuelwood prices, which makes collection and sale more profitable. We quantify both these effects. Using our estimates we show that a fifth of the fuelwood collected is consumed outside of rural areas, in nearby towns and cities. Our results imply that at the margin, fuelwood scarcity may lead to increased collection and sale, and exacerbate forest degradation.

description: The dielectric properties of CaCu3Ti4O12, a material showing colossal values of the dielectric constant, were investigated in a broad temperature and frequency range extending up to 1.3 GHz. A detailed equivalent circuit analysis of the results and two crucial experiments, employing different types of contacts and varying sample thickness, provide clear evidence that the apparently high values of the dielectric constant in CaCu3Ti4O12 are non-intrinsic and due to electrode polarization effects. The intrinsic properties of CaCu3Ti4O12 are characterized by charge transport via hopping of localized charge carriers and a relatively high dielectric constant of the order of 100.

description: The present paper examines the stability of self-enforcing International Environmental Agreements (IEAs) among heterogeneous countries in a twostage emission game. In the first stage each country decides whether or not to join the agreement, while in the second stage the quantity of emissions is chosen simultaneously by all countries. We use quadratic benefit and environmental damage functions and assume k types of countries that differ in their sensitivity to the global pollutant. We find that the introduction of heterogeneity does not yield larger stable coalitions. In particular, we show that, in the case of two types, when stable coalitions exist their size is very small, and, if the asymmetry is strong enough, they include only one type of countries. Moreover, heterogeneity can reduce the scope of cooperation relative to the homogeneous case. We demonstrated that introducing asymmetry into a stable, under symmetry, agreement can disturb stability.

description: We demonstrate how the interplay of a future e^+e^- LC at its first stage with sqrt{s} sim 500 GeV and of the LHC could lead to a precise determination of the fundamental SUSY parameters in the gaugino/higgsino sector without assuming a specific supersymmetry breaking scheme. We demonstrate this for the benchmark scenario SPS1a, taking into account realistic errors for the masses and cross sections measured at the LC with polarised beams, including errors coming from polarisation measurements, and mass measurements at the LHC. The results clearly demonstrate the complementarity of the LHC and LC, and the benefit from the joint analyses of their data.

description: Graph convolutional networks (GCNs) are a family of neural network models that perform inference on graph data by interleaving vertex-wise operations and message-passing exchanges across nodes. Concerning the latter, two key questions arise: (i) how to design a differentiable exchange protocol (e.g., a 1-hop Laplacian smoothing in the original GCN), and (ii) how to characterize the trade-off in complexity with respect to the local updates. In this paper, we show that state-of-the-art results can be achieved by adapting the number of communication steps independently at every node. In particular, we endow each node with a halting unit (inspired by Graves' adaptive computation time) that after every exchange decides whether to continue communicating or not. We show that the proposed adaptive propagation GCN (AP-GCN) achieves superior or similar results to the best proposed models so far on a number of benchmarks, while requiring a small overhead in terms of additional parameters. We also investigate a regularization term to enforce an explicit trade-off between communication and accuracy. The code for the AP-GCN experiments is released as an open-source library.

description: When minimum equity stakes in durable goods constrain a household’s debt, a persistent wage increase generates a liquidity shortage. This temporarily limits the income effect, so hours worked grow. This is the financial labor supply accelerator, which links labor supply decisions to limits on household borrowing. This paper examines its implications for the comovement of hours worked and household debt by comparing model-generated data with evidence from the PSID. The drastic deregulation of household debt markets in the early 1980s effectively reduced required equity stakes in durable goods. Since then, the estimated regression effect of mortgage debt on hours worked, interpreted as comovement rather than causality, has dropped dramatically. Analogous estimates from model-generated data display a quantitatively comparable fall after a calibrated reduction in equity requirements.

description: This paper provides a new explanation for the long-run decline in fertility, the narrowing of the gender educational gap and its reversal, which has recently occurred in many countries. It highlights the indirect effect of technological progress on the bias in parents’ preferences for sons and the impact of this bias on the demand for children and their education. We extend a standard household decision model regarding the quantity and quality of its offspring along two dimensions. First, we explicitly allow parents to value daughters and sons differently. Second, we model fertility choice as a sequential process. It is assumed that males have relative advantage in physical labor tasks and females have relative advantage in mental labor tasks, which are associated with education. For a low technological level, returns to mental labor are low and returns to physical labor are relatively high, which implies a high gender wage gap. Consequently, bias in parents’ preferences towards sons is high, which implies that families with daughters are larger and left with less education. As technology progresses, the returns to mental labor increases, gender wage gap declines, fertility becomes less uncertain, causing households to choose smaller families. As a result, relative advantages of women in education becomes more important until it dominates differences in family sizes, which, ultimately, triggers the reversal in gender educational gap.

description: We present results on the environmental dependence of the star-forming galaxy main sequence in 11 galaxy cluster fields at $1.0 < z < 1.5$ from the Gemini Observations of Galaxies in Rich Early Environments Survey (GOGREEN) survey. We use a homogeneously selected sample of field and cluster galaxies whose membership is derived from dynamical analysis. Using [OII]-derived star formation rates (SFRs), we find that cluster galaxies have suppressed SFRs at fixed stellar mass in comparison to their field counterparts by a factor of 1.4 $\pm$ 0.1 ($\sim3.3σ$) across the stellar mass range: $9.0 < \log(M_{*} /M_{\odot}) < 11.2$. We also find that this modest suppression in the cluster galaxy star-forming main sequence is mass and redshift dependent: the difference between cluster and field increases towards lower stellar masses and lower redshift. When comparing the distribution of cluster and field galaxy SFRs to the star-forming main sequence, we find an overall shift towards lower SFRs in the cluster population, and note the absence of a tail of high SFR galaxies as seen in the field. Given this observed suppression in the cluster galaxy star-forming main sequence, we explore the implications for several scenarios such as formation time differences between cluster and field galaxies, and environmentally-induced star formation quenching and associated timescales.

description: We investigate the spatial distribution of the baryonic and non-baryonic mass components in a sample of 66 virialized systems. We have used X-ray measurements to determine the deprojected temperature and density structure of the intergalactic medium and have employed these to map the underlying gravitational potential. In addition, we have measured the deprojected spatial distribution of galaxy luminosity for a subset of this sample, spanning over 2 decades in mass. With this combined X-ray/optical study we examine the scaling properties of the baryons and address the issue of mass-to-light (M/L) ratio in groups and clusters of galaxies. We measure a median mass-to-light ratio of 224 h70 M/L (solar) in the rest frame B_j band, in good agreement with other measurements based on X-ray determined masses. There is no trend in M/L with X-ray temperature and no significant trend for mass to increase faster than luminosity: M \propto Ł_{B,j}^{1.08 +/- 0.12}. This implied lack of significant variation in star formation efficiency suggests that gas cooling cannot be greatly enhanced in groups, unless it drops out to form baryonic dark matter. Correspondingly, our results indicate that non-gravitational heating must have played a significant role in establishing the observed departure from self-similarity in low mass systems. The median baryon fraction for our sample is 0.162 h70^{-3/2}, which allows us to place an upper limit on the cosmological matter density, Omega_m <= 0.27 h70^{-1}, in good agreement with the latest results from WMAP. We find evidence of a systematic trend towards higher central density concentration in the coolest haloes, indicative of an early formation epoch and consistent with hierarchical formation models.

description: An important subject of study in the field of evolutionary· biology is the relationship between phylogeny and adaptation. Many researchers are involved in studies regarding the evolutionary significance of different phenotypic patterns. In environments where strong ( and similar) selective pressures exist many characters display convergence. The similarities between populations from geographically distant but environmentally similar milieu can mislead phylogenetic considerations. This is why the identification and elimination of characters affected by convergent evolution is important before any understanding of evolutionary history is possible. Four Grammarus minus populations from West Virginia were studied. Two populations were cave inhabitants and two populations were spring inhabitants. Each spring population selected was phylogenetically related to a cave population from the same hydrologic basin. However, since both cave and spring environments offer very specific environmental conditions it was expected that many characters to display convergence between populations living in different hydrologic basins. The phylogenetic (basin) effect was surveyed based on characters that display differences between basins while the convergence was surveyed based on resemblances between populations living in similar habitats. Identification of characters displaying convergence only and phylogeny only was also done.Measurements were done on 46 characters, mostly appendages. Since a consistent difference in size exists between cave and spring organisms, a correction for size was done so that the observed differences represented shape differences.The results show that significant differences exist between the investigated populations. Many differences also exist between sexes. Most characters display a habitat effect and only a few show basin effects. After all ch8.1:acters showing habitat x basin interactions were eliminated, eleven characters ( out of 46) show convergence (habitat effect), and only four characters (out of 46) show phylogeny (basin effect). Seven characters shoved convergence only and none showed phylogeny only. Only one character displayed interaction between sex and habitat and non showed interaction between basin and sex. Many characters, ( 12 for males and 34 for females, out of 46), show interaction between habitat and basin suggesting the possible significance of such interactions in adaptation.
