description: We show empirically that fits to the color-magnitude relation of Type Ia supernovae after optical maximum can provide accurate relative extragalactic distances. We report the discovery of an empirical color relation for Type Ia light curves: During much of the first month past maximum, the magnitudes of Type Ia supernovae defined at a given value of color index have a very small magnitude dispersion; moreover, during this period the relation between $B$ magnitude and $B-V$ color (or $B-R$ or $B-I$ color) is strikingly linear, to the accuracy of existing well-measured data. These linear relations can provide robust distance estimates, in particular, by using the magnitudes when the supernova reaches a given color. After correction for light curve strech factor or decline rate, the dispersion of the magnitudes taken at the intercept of the linear color-magnitude relation are found to be around 0$^m$.08 for the sub-sample of supernovae with \BVm $\le 0^m.05$, and around 0$^m$.11 for the sub-sample with \BVm $\le 0^m.2$. This small dispersion is consistent with being mostly due to observational errors. The method presented here and the conventional light curve fitting methods can be combined to further improve statistical dispersions of distance estimates. It can be combined with the magnitude at maximum to deduce dust extinction. The slopes of the color-magnitude relation may also be used to identify intrinsically different SN Ia systems. The method provides a tool that is fundamental to using SN Ia to estimate cosmological parameters such as the Hubble constant and the mass and dark energy content of the universe.

description: We show that when one drives a charge current across noncollinear magnetic layers the two electron Coulomb scattering creates a spin flip potential at interfaces. This scattering is found when the interface potential is updated due to the spin accumulation attendant to charge flow, and it contributes in linear response to the current. With this scattering there is an injection of transverse spin distributions in a layer that propagate, and that in the steady state lead to spin currents transverse to the magnetization.

Summarized Guidelines Aid Providers in Caring for Patients with Otitis Media with Effusion
Creators: name: Nordstrom, Neil
Publisher: name: University of Massachusetts Amherst
Year: 2012

Otitis media with effusion (OME) is a disorder that can cause hearing loss in children, which can lead to speech and language delay. There are recommendations within the OME guideline and primary care providers are aware of these guidelines but do not follow them. For this project a suburban outpatient pediatric medical practice with 8 providers (4 MD’s and 4 NP’s) was studied. The 8 providers were educated and presented with an algorithm, designed by the author, organizing the OME recommendations in a flowchart. Over a 2-month period, providers referred to the algorithm and used the recommendations in practice. Then 3 interviews were completed, and providers’ answers were analyzed. There was an 87% approval rating by providers using the recommendations in practice and referring to the algorithm. Providers acknowledged that being educated on the OME guideline and using the algorithm in practice improved management of patients with OME. Educating providers on the OME guideline recommendations and supplying them with the recommendations organized in an algorithm maintains consistency and efficiency when treating patients with OME.

description: We determine the critical equation of state of the three-dimensional O(4) universality class. We first consider the small-field expansion of the effective potential (Helmholtz free energy). Then, we apply a systematic approximation scheme based on polynomial parametric representations that are valid in the whole critical regime, satisfy the correct analytic properties (Griffiths' analyticity), take into account the Goldstone singularities at the coexistence curve, and match the small-field expansion of the effective potential. From the approximate representations of the equation of state, we obtain estimates of several universal amplitude ratios. The three-dimensional O(4) universality class is expected to describe the finite-temperature chiral transition of quantum chromodynamics with two light flavors. Within this picture, the O(4) critical equation of state relates the reduced temperature, the quark masses, and the condensates around T_c in the limit of vanishing quark masses.

Obesity Group Medical Visits
Creators: name: Jaeger, Brenda L
Publisher: name: University of Massachusetts Amherst
Year: 2016

Background: Obesity is a major risk factor associated with multiple chronic diseases, presenting a significant global health challenge. Current evidence supports that group medical visits, an alternative format for the provision of primary care, are effective in disease management. 
Purpose: The goal of this project was to examine the effectiveness of group medical visits for the management of obesity in primary care. 
Methods: Individuals with a BMI greater than 30 participated in a series of six multidisciplinary group medical visits over a 12-week period. Each session included a brief individual medical visit followed by group education and discussion. Topics included; introduction and goal setting, behavior changes, nutrition, physical activity, challenges/struggles, and future goals. 
Results: Data was obtained pre and post 12 week group sessions from health records and from questionnaires.  Nine individuals age 52 to 76, with a variety of chronic medical conditions in addition to obesity, participated. Following with 12-week group sessions, attendees, as a group had a decrease in weight (P=.006), BMI (P=.007) and waist circumference (P=.019). Participants and providers indicated high levels of satisfaction. All participants found that they were able to make better choices about general health, identified group visits as more helpful than individual healthy life style discussions, and would participate in this type of visit again. 
Conclusions: This collaborative model of care needs further evaluation with larger groups; however, the group medical visit appears to be a successful method for educating and supporting lifestyle modifications for individuals with obesity in this clinical setting.
An Evaluation of an Educational Program for Improving the Accuracy of ECG Interpretation in Athletes by Primary Care Clinicians
Creators: name: Segatore, Stephen F
Publisher: name: University of Massachusetts Amherst
Year: 2016

Background: In order to identify athletes at risk for sudden cardiac death (SCD), comprehensive screening that includes ECG interpretation is needed. Many primary care providers, including physicians and nurse practitioners, have reservations about including electrocardiograms (ECG) in the screening process because they lack confidence in their ability to correctly identify normal variants in the ECG of an athlete.
Method: An educational program with previously validated interpretation criteria for normal variants of the athletic heart was presented to providers at a university based healthcare clinic the Northeast. A pre and post design was used to compare the accuracy of ECG interpretation.
Results: A total of 13 providers participated in the study. The educational program increased the accuracy of ECG interpretations. A significant decrease of false positive rates (from 21% +/-14 to 13% +/- 9 (p=0.013) occurred following participation in the educational course.
Conclusions: This study demonstrated the effectiveness of an education intervention in increasing the accuracy of ECG interpretation by primary care providers.

description: A bovinocultura de corte tem suas origens nos primórdios da ocupação do espaço agrário gaúcho e está presente em todas as regiões agroecológicas do Estado do Rio Grande do Sul. Fundamental para a formação da sociedade gaúcha, tanto do ponto de vista econômico como social, esta atividade vive atualmente um período marcado por incertezas e por um importante e vigoroso processo de reestruturação. Apesar da profusão de estudos e pesquisas, raros são os estudos que analisam a sustentabilidade, tanto do ponto de vista econômico como social e ambiental, desta atividade produtiva. Este trabalho busca, através da formatação de indicadores e índices relativos de sustentabilidade, avaliar o grau de sustentabilidade dos sistemas de produção de bovinocultura de corte do Rio Grande do Sul. A partir de entrevistas realizadas junto a 540 produtores de gado de corte no decorrer do ano de 2004, obteve-se um conjunto de informações relativas tanto as dimensões ambiental, social e econômica, como relativas aos critérios de produtividade, estabilidade/resiliência, equidade e autonomia apresentados pelos bovinocultores de corte. A análise conteve-se na comparação entre os Índices Relativos das Dimensões (IRD), dos Critérios (IRC) e de Sustentabilidade (IRS) de cada tipo de sistema de produção. Os resultados apontam a existência de oito tipos de sistemas de produção relevantes para esta análise. Os índices de sustentabilidade apontam o sistema de produção do tipo cinco como mais sustentável, seguido pelos tipos sete, três, seis, quatro, dois, e, por último os tipos oito e um, os quais estão mais próximos do que se poderia chamar de situação de insustentabilidade.
Depression Screening for Adolescents in Primary Care

Publisher: name: University of Massachusetts Amherst
Year: 2016

Depression is a serious problem in the United States with suicide the potential catastrophic result of this disease.  Suicide is the third leading cause of death for youth between the ages of 10 and 24.  At any one time, 5% to 6% of adolescents experience major depressive symptoms, with lifetime rates of major depression among adolescents reaching up to 20%.  Adolescents see their primary care providers on average once or twice a year making this the ideal setting for identification of adolescent depression.  A review of the literature supports the use of instruments to identify depression that can be incorporated during routine health exams and the need for depression screening in primary care.  The goal of this quality improvement project was to implement depression screening into a pediatric primary care setting.  This was accomplished through the development of a process to disseminate and score PHQ-9 questionnaires at all health maintenance visits.

description: We report calculations of oscillator strengths for the far infrared absorption of light by the excitonic complexes Xn- (the excess charge, n, ranging from one to four) confined in quantum dots. The magnetic field is varied in an interval which corresponds to ``filling factors'' between 2 and 3/5. Electron-hole interaction effects are seen in the deviations of the peak positions from the Kohn lines, and in the spreading of the oscillator strengths over a few final states. Transition densities are used as an additional tool to characterize the absorption peaks.

description: Proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD) are two complementary singular-value decomposition (SVD) techniques that are widely used to construct reduced-order models (ROMs) in a variety of fields of science and engineering. Despite their popularity, both DMD and POD struggle to formulate accurate ROMs for advection-dominated problems because of the nature of SVD-based methods. We investigate this shortcoming of conventional POD and DMD methods formulated within the Eulerian framework. Then we propose a Lagrangian-based DMD method to overcome this so-called translational issues. Our approach is consistent with the spirit of physics-aware DMD since it accounts for the evolution of characteristic lines. Several numerical tests are presented to demonstrate the accuracy and efficiency of the proposed Lagrangian DMD method.
Saturation and parton level Cronin effect: enhancement vs suppression of gluon production in p-A and A-A collisions

description: We note that the phenomenon of perturbative saturation leads to transverse momentum broadening in the spectrum of partons produced in hadronic collisions. This broadening has a simple interpretation as parton level Cronin effect for systems in which saturation is generated by the "tree level" Glauber-Mueller mechanism. For systems where the broadening results form the nonlinear QCD evolution to high energy, the presence or absence of Cronin effect depends crucially on the quantitative behavior of the gluon distribution functions at transverse momenta kt outside the so called scaling window. We discuss the relation of this phenomenon to the recent analysis by Kharzeev-Levin-McLerran of the momentum and centrality dependence of particle production in nucleus-nucleus collisions at RHIC.

Moving Beyond the Ask: Improving Tobacco Cessation Intervention Delivery in Primary Care
Creators: name: Johnston, Joan D
Publisher: name: University of Massachusetts Amherst
Year: 2016

Background: Quitting smoking at any time benefits health. Primary care visits provide the opportunity to advise current tobacco users to initiate a quit attempt, explain available quit options and arrange for adequate follow-up care. Purpose: The purposes of this DNP project were to provide a staff development educational activity and introduce a workflow modification intended to extend the effectiveness of a tobacco cessation intervention delivered during an office visit. Methods: Medical Assistant staff members responsible for patient recruitment completed a pre-test, viewed an online tobacco educational module and completed a post-test.  Using convenience sampling methodology, a cohort of self-identified current tobacco users after being asked if they were contemplating quitting, were recruited, provided consent and became eligible to participate in follow up phone call(s) and an experience survey. Staff members were provided an anonymous staff experience survey. Results:  33% of the nine patients who enrolled, consented and participated in follow up telephone call(s) decided on a quit date (but may not have actually quit) by the end of the project period.  Conclusion: Identifying current smokers who are thinking about quitting, providing information and resources to them and arranging for ongoing support may extend the impact of tobacco cessation activity beyond simply asking about tobacco use during the office visit. This process shows promise as a technique to move interested patients towards selecting a quit date while providing the practice with a method to develop sustainable practice-based interventions that integrate positive health behavior change as one of their components.

Using a Delayed Antibiotic-Prescribing Education Intervention to Prevent Antibiotic Overuse in the Treatment of Respiratory Tract Infections
Creators: name: Muhia, Catherine L
Publisher: name: University of Massachusetts Amherst
Year: 2016

Background: Antibiotics have been overprescribed to patients with respiratory infection in outpatient clinics in the United States. Antibiotic overuse has led to increased risk for antibiotic resistance and complications related to side effects. A review of the literature suggests that delayed antibiotic prescribing is an effective intervention that can be used to prevent antibiotic overuse. Delayed antibiotic prescribing is an evidence-based strategy where a patient is either issued with an antibiotic prescription and advised to delay filling it or to pick it up at an agreed location only if symptoms persist beyond the expected natural history of illness or deteriorate. Purpose: The purpose of this quality improvement project was to improve primary care providers’ knowledge about delayed antibiotic prescribing strategy and decrease inappropriate prescribing of antibiotics in the treatment of respiratory tract infections. The study used a one-group pre- and posttest design to measure providers’ knowledge of delayed antibiotic-prescribing strategy. Results: A convenience sample of 30 providers participated in the project. After the education intervention, there was a significant improvement in knowledge test questionnaire scores: Paired t (30) = 13.24, p < .001. 77% (n=23) of the prescribers expressed their likelihood to adopt delayed prescribing in their practice. Discussion: The findings indicate that the delayed antibiotics educational intervention can improve providers’ knowledge, increase their likelihood to adopt intervention in practice, which may prevent complications related to antibiotic overuse. This project had limitations related to implementation and evaluation time constraints, small sample size, and lack of a control group. Ongoing education of providers and patients is an essential intervention for preventing inappropriate antibiotic use in the treatment of respiratory tract infections.

description: Short-timescale microlensing events are likely to be produced by substellar brown dwarfs (BDs), but it is difficult to securely identify BD lenses based on only event timescales $t_{\rm E}$ because short-timescale events can also be produced by stellar lenses with high relative lens-source proper motions. In this paper, we report three strong candidate BD-lens events found from the search for lensing events not only with short timescales ($t_{\rm E} \lesssim 6~{\rm days}$) but also with very small angular Einstein radii ($θ_{\rm E}\lesssim 0.05~{\rm mas}$) among the events that have been found in the 2016--2019 observing seasons. These events include MOA-2017-BLG-147, MOA-2017-BLG-241, and MOA-2019-BLG-256, in which the first two events are produced by single lenses and the last event is produced by a binary lens. From the Bayesian analysis conducted with the combined $t_{\rm E}$ and $θ_{\rm E}$ constraint, it is estimated that the lens masses of the individual events are $0.051^{+0.100}_{-0.027}~M_\odot$, $0.044^{+0.090}_{-0.023}~M_\odot$, and $0.046^{+0.067}_{-0.023}~M_\odot/0.038^{+0.056}_{-0.019}~M_\odot$ and the probability of the lens mass smaller than the lower limit of stars is $\sim 80\%$ for all events. We point out that routine lens mass measurements of short time-scale lensing events require survey-mode space-based observations.

description: The HEGRA Cherenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive stellar association known in the Galaxy, estimated to contain ~2600 OB type members alone. It has been previously argued that the large scale shocks and turbulence induced by the multiple interacting supersonic winds from the many young stars in such associations may play a role in accelerating Galactic cosmic rays. Indeed, Cyg OB2 also coincides with the non-variable MeV-GeV range unidentified EGRET source, 3EG 2033+4118. We report on the near-simultaneous follow-up observations of the extended TeV source region with the CHANDRA X-ray Observatory and the Very Large Array (VLA) radio telescope obtained in order to explore this possibility. Analysis of the CO, HI, and IRAS 100 micron emissions shows that the TeV source region coincides with an outlying sub-group of powerful OB stars which have evacuated or destroyed much of the ambient atomic, molecular and dust material, and which may be related to the very high-energy emissions. An interesting SNR-like structure is also revealed near the TeV source region in the CO, HI and radio emission maps. Applying a numerical simulation which accurately tracks the radio to gamma-ray emission from primary hadrons as well as primary and secondary e+/-, we find that the broadband spectrum of the TeV source region favors a predominantly nucleonic - rather than electronic - origin of the high-energy flux, though deeper X-ray and radio observations are needed to confirm this. A very reasonable, ~0.1%, conversion efficiency of Cyg OB2's extreme stellar wind mechanical luminosity to nucleonic acceleration to ~PeV (10^15 eV) energies is sufficient to explain the multifrequency emissions.

Use of the Geriatric Depression Scale to Improve Screening, Identification and Intervention for Depression Among Older Adults in the Primary Care Setting
Creators: name: Glorighian, Christina
Publisher: name: University of Massachusetts Amherst
Year: 2016

The purpose of this quality improvement project was to determine whether increased use of an age-specific depression screening tool, the Geriatric Depression Scale (GDS 15-item), improved screening for depression in elderly patients and improved identification of and intervention for depression among elderly patients in a selected primary care setting.  Depression affects approximately two million older adults and has been found to be a common yet frequently undiagnosed condition among geriatric patients in the primary care setting.  The extent of undiagnosed depression helps to justify the need to improve geriatric depression screening in the primary care setting.  A review of the literature demonstrates the efficacy of the GDS tool in screening for geriatric depression.  Theoretical frameworks used to underpin the structure and guide this project include the Shannon-Weaver Model of Communication and Lewin’s Change Theory as they provide the elements vital to effective communication and change, respectively.  The project design and methods included a pre- and post-intervention data analysis to examine the implementation of the GDS 15-item tool into the primary care practice setting.  The results of this project support the importance of screening for depression in patients 65 years and older more frequently (ideally at six month intervals) and utilizing an age-specific depression screening tool such as the GDS-15 in the selected primary care setting.  Future work should focus on increasing the frequency and standard use of the GDS 15-item in geriatric patients in primary care settings.

We have shown that the cross ratio parameter space \mathcal{C}_τassociated with τ, which can be identified with the set of all pairs of a projective structure and a circle packing on it with nerve isotopic to τ, is homeomorphic to \mathbb{R}^{6g-6}, and moreover that the forgetting map of \mathcal{C}_τto the space of projective structures is injective. In this paper, we show that the composition of the forgetting map with the uniformization from \mathcal{C}_τto the Teichmüller space \mathcal{T}_g is proper.

description: se and What Chatter Matters? The Effect of Tweets on Movie Sales Abstract: Social broadcasting networks such as Twitter in the U.S. and "Weibo" in China are transforming the way online word of mouth (WOM) is disseminated and consumed in the digital age. In the present study, we investigated whether and how Twitter WOM affects movie sales by estimating a dynamic panel data model using publicly available data and well-known machine learning algorithms. We found that chatter on Twitter does matter; however, the magnitude and direction of the effect depends on whom the WOM is from and what the WOM is about. Measuring Twitter users' in uence by how many followers they had, we found that the effect of WOM from more in fluential users is signifcantly larger than that from less in uential users. In support of some recent findings about the importance of WOM valence on product sales, we also found that positive Twitter WOM increases movie sales, whereas negative WOM decreases them. Interestingly, we found that the strongest effect on movie sales comes from those tweets in which the authors expressed their intention to watch a certain movie. We attribute this finding to the dual effects of such intention tweets on movie sales: the direct effect through the WOM author's own purchase behavior, and the indirect effect through either the awareness effect or the persuasive effect of the WOM on its recipients. Our findings provide new perspectives to understand the effect of WOM on product sales and have important managerial implications. For example, our study reveals the potential values of monitoring people's intentions and sentiments on Twitter and identifying in uential users for companies wishing to harness the power of social broadcasting networks.

description: The quality of datasets is a critical issue in big data mining. More interesting things could be mined from datasets with higher quality. The existence of missing values in geographical data would worsen the quality of big datasets. To improve the data quality, the missing values are generally needed to be estimated using various machine learning algorithms or mathematical methods such as approximations and interpolations. In this paper, we propose an adaptive Radial Basis Function (RBF) interpolation algorithm for estimating missing values in geographical data. In the proposed method, the samples with known values are considered as the data points, while the samples with missing values are considered as the interpolated points. For each interpolated point, first, a local set of data points are adaptively determined. Then, the missing value of the interpolated point is imputed via interpolating using the RBF interpolation based on the local set of data points. Moreover, the shape factors of the RBF are also adaptively determined by considering the distribution of the local set of data points. To evaluate the performance of the proposed method, we compare our method with the commonly used k Nearest Neighbors (kNN) interpolation and Adaptive Inverse Distance Weighted (AIDW) methods, and conduct three groups of benchmark experiments. Experimental results indicate that the proposed method outperforms the kNN interpolation and AIDW in terms of accuracy, but worse than the kNN interpolation and AIDW in terms of efficiency.

Risk and Uncertainty

description: After synthesizing the results of the economic analyses carried on market risk management in agriculture, a complex and recurring object in the agricultural policy debates, we propose some thoughts to help guide political action. To begin with, this action must be directed towards the regulation (control) of market risk management rather than the physical markets. The implementation of this general recommendation requires the continuation of specific economic works.

description: We present numerical evidence for the hypothesis that, in the planar limit, four dimensional Euclidean Yang-Mills theory on a finite symmetrical four-torus breaks chiral symmetry spontaneously when the length of the sides l is larger than a critical value l_c with a bilinear condensate whose value is independent of l. Therefore spontaneous symmetry breaking occurs at finite volume and infinite N_c reduction holds for the chiral condensate.

Demand and Price Analysis

description: The stakes of the Common Agricultural Policy (CAP) after 2013 are closely linked with the situation which will prevail on the Community and international agricultural markets in the next decade. Here we propose a summary and discussion on the existing information regarding the markets for agricultural products after 2010, relying on three projections proposed by international bodies, by 2020 or 2025: i) “prospects for agricultural markets and incomes in the European Union” centred on the projections (2010-2020) of the Community markets for major agricultural products and followed by an analysis of the development induced from agricultural incomes, produced by the European Commission (EC); ii) the 2010-2020 projections of the world agricultural markets achieved by the OECD and the FAO with the model AGLINK/COSIMO; and iii) the projections 2011-2025 provided by the American Institute FAPRI with the eponymous model. The main results indicate a moderate increase in agricultural prices with a greater risk of variability, growth in plant productions supported by the demand for biofuels, and a high exposure to competition in animal productions of the community. These results are weakened by the uncertain economic environment and are mainly sensitive to assumptions concerning productivity reserves and demand performances.

description: The emergence of extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae has been increasing rapidly across the world. The presence of virulence factors in ESBL producers further adds to the pathogenicity and severity of infection, which often complicate empirical therapy and sometimes result in treatment failures. In the present study, 227 non-repeated clinical isolates of K. pneumoniae obtained from different clinical specimens from a tertiary care hospital in India were analyzed to detect the genes responsible for ESBL production (blaTEM, blaCTX-M, and blaSHV), virulence (fimH-1, mrkD, entB, irp-1), and capsule production (K1-K2). Phenotypically identified 72 ESBL producing K. pneumoniae isolates were further subjected to PCR based genotypic analysis but only 20 were found to have at least one of the ESBL producing genes. blaTEM was the most predominant gene (100%), followed by blaSHV (90%), and blaCTX-M (85%). Similarly, the most common virulence genes were fimH-1 (70%), entB (65%), markD (55%), irp-1 (25%), K1 (25%), and K2 (20%). REP-PCR profile separated them into five major clusters (I-V), indicating the existing heterogeneity among the isolates. The resistance profile data obtained from the present study can serve as the information base to understand the infection pattern prevailing in the hospital and for physicians to recommend suitable antibiotics for the patients.

description: The aim of this paper is to analyse algorithms for constructing presentations of graph braid groups from the point of view of anyonic quantum statistics on graphs. In the first part of this paper, we provide a comprehensive review of an algorithm for constructing so-called minimal Morse presentations of graph braid groups that relies on discrete Morse theory. Next, we introduce the notion of a physical presentation of a graph braid group as a presentation whose generators have a direct interpretation as particle exchanges. We show how to derive a physical presentation of a graph braid group from its minimal Morse presentation. In the second part of the paper, we study unitary representations of graph braid groups that are constructed from their presentations. We point out that algebraic objects called moduli spaces of flat bundles encode all unitary representations of graph braid groups. For $2$-connected graphs, we conclude the stabilisation of moduli spaces of flat bundles over graph configuration spaces for large numbers of particles. Moreover, we set out a framework for studying locally abelian anyons on graphs whose non-abelian properties are only encoded in non-abelian topological phases assigned to cycles of the considered graph.

description: We explore how the estimated star formation rate (SFR) of a sample of isolated, massive dusty star-forming galaxies at early cosmic epochs ($1.5 < z < 3.5$) changes when their ultraviolet (UV) to near-infrared (NIR) spectral energy distribution is extended to longer wavelengths by adding far-infrared/sub-millimeter data to trace the reprocessed radiation from dust heated by young massive stars. We use large-area surveys with multi-wavelength datasets that include DECam UV-to-optical, VICS82 NIR, Spitzer-IRAC NIR, and Herschel-SPIRE far-infrared/sub-millimeter data. We find that the inclusion of far-infrared/sub-millimeter data leads to SFRs that span $\sim$100-3500 $M_{\odot} yr^{-1}$ and are higher than the extinction-corrected UV-based SFR by an average factor of $\sim$3.5, and by a factor of over 10 in many individual galaxies. Our study demonstrates the importance of far-IR/sub-millimeter data for deriving accurate SFRs in massive dusty galaxies at early epochs, and underscores the need for next-generation far-IR/sub-millimeter facilities with high sensitivity, field of view, and angular resolution.
