description: We demonstrate that a population of Active Galactic Nuclei (AGN) can describe the observed spectrum of ultra-high-energy cosmic rays (UHECRs) at and above the ankle, and that the dominant contribution comes from low-luminosity BL Lacs. An additional, subdominant contribution from high-luminosity AGN is needed to improve the description of the composition observables, leading to a substantial neutrino flux that peaks at EeV energies. We also find that different properties for the low- and high-luminosity AGN populations are required; a possibly similar baryonic loading can already be excluded from current IceCube observations. We also show that the flux of neutrinos emitted from within the sources should outshine the cosmogenic neutrinos produced during the propagation of UHECRs. This result has profound implications for the ultra-high-energy ($\sim$EeV) neutrino experiments, since additional search strategies can be used for source neutrinos compared to cosmogenic neutrinos, such as stacking searches, flare analyses, and multi-messenger follow-ups.

description: This article highlights examples of innovative approaches in regional water problem-solving contained in tribal settlements, providing readers with a sense of the possibilities that tribal participation brings to western water management. Many tribal settlements use economic incentives in ways useful to consider in a broader water management context. The article highlights economic components of several specific settlements and concludes by summarizing ways in the economic principles and incentives they illustrate can be more broadly applied in addressing water challenges. Figure 1 lists the tribal nations that are referred to in this article and shows the area where these tribes’ reservations are located.
The effectiveness of a self-contained special education program for seriously emotionally disturbed secondary level students

description: The benefits of a self-contained special education program offered to seriously emotionally disturbed secondary level students were investigated in relation to: self-concept; outcome measures associated with progress toward graduation; return to a regular mainstream classroom; and the opinions of students, parents or guardians, and the professional staff directly associated with the program. All 108 subjects and their parents or guardians were included in a multimethod, single case study approach, where the case was a single program site. Personal, educational, and demographic characteristics of the 108 students were documented. Data collection and analysis procedures included administration of the Piers-Harris Children's Self-Concept Scale, examination of school records, and surveys of student, parent or guardian, and professional staff opinions. The findings indicated that students maintained adequate self-concept, and outcome measures indicated progress towards graduation, with the exception of attendance. Dropout rates were minimal, students earned passing grades, some students returned to the mainstream of regular education, and all but one senior graduated. Student opinions of the program were similar to school programs rated by regular education students; the parents or guardians and professional staff viewed the program favorably. The National Longitudinal Transition Study identified the seriously emotionally disturbed as the most failure and dropout prone of all disability groups; however, this study demonstrates that when seriously emotionally disturbed students were educated in this self-contained program they remained engaged in the school process indicating progress towards a diploma and successful transition to young adulthood. Benefits of the self-contained program for seriously emotionally disturbed secondary level students were confirmed.

description: For the first time in the physics literature, the Lorentz representations of all 2,147,483,648 bosonic degrees of freedom and 2,147,483,648 fermionic degrees of freedom in an unconstrained eleven dimensional scalar superfield are presented. Comparisons of the conceptual bases for this advance in terms of component field, superfield, and adinkra arguments, respectively, are made. These highlight the computational efficiency of the adinkra-based approach over the others. It is noted at level sixteen in the 11D, N = 1 scalar superfield, the {65} representation of SO(1,10), the conformal graviton, is present. Thus, Adinkra-based arguments suggest the surprising possibility that the 11D, N = 1 scalar superfield alone might describe a Poincare supergravity prepotential in analogy to one of the off-shell versions of 4D, N = 1 superfield supergravity.

description: Part-level representations are important for robust person re-identification (ReID), but in practice feature quality suffers due to the body part misalignment problem. In this paper, we present a robust, compact, and easy-to-use method called the Multi-task Part-aware Network (MPN), which is designed to extract semantically aligned part-level features from pedestrian images. MPN solves the body part misalignment problem via multi-task learning (MTL) in the training stage. More specifically, it builds one main task (MT) and one auxiliary task (AT) for each body part on the top of the same backbone model. The ATs are equipped with a coarse prior of the body part locations for training images. ATs then transfer the concept of the body parts to the MTs via optimizing the MT parameters to identify part-relevant channels from the backbone model. Concept transfer is accomplished by means of two novel alignment strategies: namely, parameter space alignment via hard parameter sharing and feature space alignment in a class-wise manner. With the aid of the learned high-quality parameters, MTs can independently extract semantically aligned part-level features from relevant channels in the testing stage. MPN has three key advantages: 1) it does not need to conduct body part detection in the inference stage; 2) its model is very compact and efficient for both training and testing; 3) in the training stage, it requires only coarse priors of body part locations, which are easy to obtain. Systematic experiments on four large-scale ReID databases demonstrate that MPN consistently outperforms state-of-the-art approaches by significant margins.

description: The diagnosis of autism spectrum disorder (ASD) is a complex, challenging task as it depends on the analysis of interactional behaviors by psychologists rather than the use of biochemical diagnostics. In this paper, we present a modeling approach to ASD diagnosis by analyzing acoustic/prosodic and linguistic features extracted from diagnostic conversations between a psychologist and children who either are typically developing (TD) or have ASD. We compare the contributions of different features across a range of conversation tasks. We focus on finding a minimal set of parameters that characterize conversational behaviors of children with ASD. Because ASD is diagnosed through conversational interaction, in addition to analyzing the behavior of the children, we also investigate whether the psychologist's conversational behaviors vary across diagnostic groups. Our results can facilitate fine-grained analysis of conversation data for children with ASD to support diagnosis and intervention.

description: We show that attempts to construct the standard model, or the MSSM, by placing D3-branes and D7-branes at a Z_N orbifold or orientifold singularity all require that the electroweak Higgs content is non-minimal. For the orbifold the lower bound on the number n(H) + n({\bar{H}}) of electroweak Higgs doublets is the number n(q^c_L)=6 of quark singlets, and for the orientifold the lower bound can be one less. As a consequence there is a generic flavour changing neutral current problem in such models.

description: The purpose of the study was to ascertain the perceptions of a sample of professional counselors regarding how important holding five specific credentials is to a counselor's career and how helpful these credentials are in securing each of twelve career benefits presented in the Perceptions of Professional Counselors Inventory (PCCI). The following counselor credentials were considered: (a) Licensed Professional Counselor (LPC), (b) Certified Professional Counselor (CPC), (c) Certified Clinical Mental Health Counselor (CCMHC), (d) Certified Rehabilitation Counselor (CRC), and (e) National Certified Counselor (NBCC). In early 1993, a national sample of 1,604 professional members of the American Counseling Association was surveyed by mail using the PCCI, a self-report instrument, which was developed by the author to obtain the data needed to address five research questions related to the study problem. The data were tallied into frequency distributions; means and ranks of the means were calculated; and chi-square analyses were conducted to determine the significance of differences in responses at the p $\leq$.01 level. A significant relationship was found between the type of credential and its perceived helpfulness to the achievement of each of the twelve benefits of reference, with the LPC eliciting a larger percentage of responses in the "essential" category than did the other credentials. These results strongly indicate that the LPC credential, among those five considered, is seen as both the most important to a counselor's career and most helpful to obtaining the career benefits. In general, credentials other than the LPC were considered less essential but "slightly" to "very helpful" to the achievement of nine of the twelve benefits. However, there were significant differences regarding the LPC's helpfulness to the attainment of eight of the twelve career benefits when comparing study participants who hold some type of credential (not necessarily the LPC) and those who do not. The findings seem to warrant the conclusion that the LPC is the primary credential that counselors should acquire in their attempt to realize the twelve career benefits of reference, especially those related to third-party reimbursement, preferred status in job hiring, and qualifications necessary to be seen as an expert witness.

description: Pinnularia sp 1 (Figs 44–47)
Valves linear with parallel or, in larger specimens, weakly undulated margins, and non-protracted, broadly rounded apices. Valve dimensions (n=11): length 25–35 µm, width 5.0– 6.5 µm. Axial area narrow, linear, clearly widening towards the central area. Central area forming a large rhombic fascia, about 1/3 to 1/4 of valve length, expanded to the margins. Raphe slightly curved. Central raphe endings extending into the central area well beyond the last central striae, unilaterally deflected and finishing in relatively distant drop-like pores. Terminal fissures almost indistinct,?-shaped. Striae strongly radiate in the middle, abruptly changing their direction to convergent toward the valve ends, 11–13 in 10 µm. Longitudinal lines absent.
 Habitat and distribution:—This is an extremely rare species on Livingston Island. Only a few valves were found on Hurd Peninsula, in streams, in a vegetation of wet mosses close to streams, brooks or puddles.
 Observations:— These Antarctic specimens belong to the complex of species around P. divergentissima (Grunow in Cleve & Möller 1879: 186) Cleve (1895: 77) sensu Krammer (2000). Pinnularia divergentissima and its varieties can be separated based on a different valve outline, having mostly convex margins and smaller subrostrate to capitate valve ends, as well as by a slightly higher number of striae (according to Krammer 2000: 12–14 vs 11–13 in 10 µm) and a smaller central area. The most similar species is P. krammeri Metzeltin (in Lange-Bertalot & Metzeltin 1996: 98), described from Finland. The main differences between the Antarctic population and P.krammeri include a larger valve width of P. krammeri (6.7–7.8 µm vs. 5.0– 6.5 µm), a comparably smaller central area and more closely spaced proximal raphe endings. Since only a few valves have been observed, it is too early to conclude whether they should be described as an independent species or belong to P. krammeri.

description: The intrinsic nature of glass states or glass transitions has been a mystery for a long time. Recently, more and more studies tend to show that a glass locates at a specific potential energy landscape (PEL). To explore how the flatness of the PEL related to glass transition, we develop a method to adjust the PEL in a controllable manner. We demonstrate that a relatively flat PEL is not only necessary but also sufficient for the formation of a nanoscale glass. We show that: (1) as long as a nanocluster is located in a region of PEL with local minimum deep enough, it can undergo a first-order solid-liquid phase transition; and (2) if a nanocluster is located in a relatively flat PEL, it can undergo a glass transition. All these transitions are independent of its structure symmetry, order or disorder. Our simulations also uncover the direct transition from one potential energy minimum to another below the glass transition temperature, which is the consequence of flat PELs.

The professionalization of law enforcement: The effects of social stratification factors and law enforcement sector on perceptions of professionalization among students at the FBI National Academy
Creators: name: Hunsinger, Dennis Alan
Publisher: name: American University
Year: 2023

description: This study examines how an individual's Social Stratification factors has effected perceptions of how professionalized he or she has become in their law enforcement career. Social Stratification factors are identified as parent's financial/educational background, and the law enforcement officer's race, religion, gender, age, current class, and educational level. Professionalization is measured by a belief in: Altruism (community vs. self interest); ethical standards; need for a lengthy training program and certification process; need for professional associations as opposed to trade unions; need for political agitation to win legal and popular support; sense of calling; and self-regulation or autonomy. In addition, the study reviews what effect an individual's placement within the various sectors of law enforcement (i.e., federal, state, county, etc.) has on his or her (as well as each sector's) perceptions of professionalization. This study relies on responses (through a directly-administered questionnaire) from students in attendance at three sessions of the FBI National Academy. Each session had an enrollment of approximately 250 students. The findings of the study can be summarized as follows: (1) There is a statistically significant relationship between Social Stratification and an individual's perception of how professionalized he or she has become in their occupation. (2) There is statistical evidence that a hierarchy exists among sectors of law enforcement, both in how sectors view themselves and each other. The data clearly supports a hierarchy that puts the Federal sector on top, followed by State, City, Military, County, International, and Campus sectors. (3) In spite of this emerging hierarchy, there is no relationship between Social Stratification and the sector in which an officer works, or sector and how professionalized an officer believes he or she has become.

description: Common groundwater management concerns that are driving policy change worldwide include aquifer depletion, surface water-groundwater interaction, and water quality degradation. This article discusses recent innovations in groundwater quantity management from around the northern and central High Plains region of the United States, where much of the policy change has occurred at a local level. There are several principles underlying the development of new groundwater management tools. Local and stakeholder input are common, generally effective, and are often more politically feasible than top-down regulations. Evidence is emerging that the behavioral and signaling aspects of policy have been effective in changing producer behavior.

description: Rules about water use in the West evolved independently from those meant to improve water quality. Sometimes rules governing use have a negative effect on water quality and vice versa. We look at the interaction of use and quality rules in the Lower Arkansas River Valley (LARV) in Southeast Colorado. The adoption of water-saving sprinkler irrigation systems has lagged behind adoption in similar regions. The lag is primarily because the LARV has unique use rules that require replacing water savings to the river when a more efficient system is adopted. At the same time, several studies have found that sprinklers can help with pollution problems from nitrogen, selenium and salinity. We show that economists, working with other sciences, can make sophisticated estimates about the impacts conservation systems. However, it is difficult to present those complex results in a way that helps stakeholders examine the options. An example is presented that allows farmers and others to compare the impacts of different conservation systems across multiple objectives in a simple and meaningful way. Researchers are now better equipped than ever to work with local stakeholders to evaluate conservation systems and address multiple objectives.

description: We consider a color octet scalar particle and its exotic decay in the channel gluon-$γ$ using an effective Lagrangian description for its strong and electromagnetic interactions. Such a state is present in many extensions of the Standard Model, and in particular in composite Higgs models with top partial compositeness, where couplings to photons arise via the Wess-Zumino-Witten term. We find that final states with one or two photons allow for a better reach at the LHC, even for small branching ratios. Masses up to $1.2$ TeV can be probed at the HL-LHC by use of all final states. Finally, we estimate the sensitivity of the hadronic FCC.

description: For space-based laser communications, when the mean photon number per received optical pulse is much smaller than one, there is a large gap between communications capacity achievable with a receiver that performs individual pulse-by-pulse detection, and the quantum-optimal "joint-detection receiver" that acts collectively on long codeword-blocks of modulated pulses; an effect often termed "superadditive capacity". In this paper, we consider the simplest scenario where a large superadditive capacity is known: a pure-loss channel with a coherent-state binary phase-shift keyed (BPSK) modulation. The two BPSK states can be mapped conceptually to two non-orthogonal states of a qubit, described by an inner product that is a function of the mean photon number per pulse. Using this map, we derive an explicit construction of the quantum circuit of a joint-detection receiver based on a recent idea of "belief-propagation with quantum messages" (BPQM) (arXiv:1607.04833). We quantify its performance improvement over the Dolinar receiver that performs optimal pulse-by-pulse detection, which represents the best "classical" approach. We analyze the scheme rigorously and show that it achieves the quantum limit of minimum average error probability in discriminating 8 (BPSK) codewords of a length-5 binary linear code with a tree factor graph. Our result suggests that a BPQM-receiver might attain the Holevo capacity of this BPSK-modulated pure-loss channel. Moreover, our receiver circuit provides an alternative proposal for a quantum supremacy experiment, targeted at a specific application that can potentially be implemented on a small, special-purpose, photonic quantum computer capable of performing cat-basis universal qubit logic.

description: Virtual radiative corrections due to the long range Coulomb forces of heavy nuclei with charge Z may lead to sizeable corrections to the Born cross section usually used for lepton-nucleus scattering processes. An introduction and presentation of the most important issues of the eikonal approximation is given. We present calculations for forward electroproduction production of rho mesons in a framework suggested by the VDM (vector dominance model), using the eikonal approximation. It turns out that Coulomb corrections may become relatively large. Some minor errors in the literature are corrected.

description: Based on a survey of graduating PhD students in the U.S., we study the determinants of location of their first jobs. We consider how locating in Canada versus the U.S. for all graduates is influenced by both their background and time­varying factors that af-­ fect international mobility. We also study the choice of European graduates between North America and returning to Europe. We find that in many cases macro factors have the expected effect of choices after controlling for biases for home, which depend upon background variables in expected ways.
Testing linearity with applications to clines
Creators: name: Kondelis, Euripides C.
Publisher: name: American University
Year: 2023

description: Spatial and geographic measures of biological diversity are often represented by clines. A cline has been described as a gradient in a measurable character. Means of morphometric characters studied at different locations are plotted to provide a graphical representation of a cline often displayed as an S-shaped curve. Of special interest is testing whether two clines based on different morphometric measures are identical. By graphing one cline against another in a cline-cline plot, testing equality can be reduced to testing linearity. We consider several tests of the equality of clines by testing linearity of the cline-cline plot against S-shaped alternatives. Many of these tests are based on third differences of the cline-cline graph. The criterion of Asymptotic Relative Efficiency is used to compare the tests. Theoretical results show that a least-squares t-test performs better than the others considered. Simulations show that the one-sample t-test performs quite well when the errors used are normally distributed while the two nonparametric tests considered are likely more appropriate alternatives especially when the errors are not normally distributed. Simulations also show that in terms of power, the performance of the third-difference-based tests is very satisfactory once specific conditions and assumptions are satisfied. These conditions are equal sample sizes from each location, constant error variability, equally distanced means for these groups and independence of variables. However when these third-difference-based tests are applied to data in which some or all of these conditions are violated, the result is a considerable loss of power.

description: The continued increase in areal densities in magnetic recording makes it crucial to understand magnetization reversal in nanoparticles. We present finite-temperature micromagnetic simulations of hysteresis in Fe nanopillars with the long axis tilted at angles from 0 degrees to 90 degrees to the applied sinusoidal field. The field period is 15 ns, and the particle size is 9 x 9 x 150 nm. The system is discretized into a rectangular pillar of 7 x 7 x 101 spins each with uniform magnetization. At low angles, reversal begins at the endcaps and proceeds toward the center of the particle. At ninety degrees, reversal proceeds along the entire length of the particle (save at the ends). The switching field was observed to increase over the entire range of angles, consistent with recent experimental observations. A second, lower-resolution micromagnetic simulation with 1 x 1 x 17 spins, does not agree with experiment, but shows behavior very similar to that of the Stoner-Wohlfarth model of coherent rotation.

Influence on smoothness in penalized likelihood regression for binary data

description: Penalized likelihood is a nonparametric regression technique that can be used to estimate a mean function for binary data. This fitting procedure incorporates a penalty for roughness in the fitting function; the weight given to the penalty is controlled by a 'smoothing parameter'. As part of the fitting procedure, the optimal value of the smoothing parameter and the optimal function estimate are determined from the data. We wish to measure the sensitivity of the smoothing parameter to gross changes in the data. Since penalized likelihood curve fitting requires both a grid search to determine the optimal value of the smoothing parameter and iterative solution for each grid point, naive calculations that determine the change in the optimal value of the smoothing parameter when each data value is modified are computationally intensive and time-consuming. We have developed techniques based on analytical and numerical approximations for measuring sensitivity in penalized likelihood regression with binary data. These techniques have been applied to selected data sets to compute changes in the smoothing parameter resulting from changes in individual data values.

description: Standard models of international risk sharing with complete asset markets predict a positive association between relative consumption growth and real exchange-rate depreciations across countries. The striking lack of evidence for this link — the consumption/ realexchange- rate anomaly or Backus-Smith puzzle — has prompted research on risk-sharing indicators with incomplete asset markets. That research generally implies that the association holds in forecasts, rather than realizations. Using professional forecasts for 28 countries for 1990-2008 we find no such association, thus deepening the puzzle. Independent evidence on the weak link between forecasts for consumption and real interest rates suggests that the presence of ‘hand-to-mouth’ consumers may help to explain the evidence.

description: This paper examines the role of cultural factors in driving the politics and shape of migration policy. We show that there exists a broad political failure that results in inefficiently high barriers restricting the import of temporary foreign workers and also admitting an inefficiently large number of permanent migrants, but not enough to fill any labor shortage in the economy. We show that countries that are poor at cultural assimilation are better positioned to take advantage of shortterm foreign worker programs than more culturally diverse and tolerant countries. A striking implication is that relaxing restrictions on the mobility of migrant workers across employers has the potential to raise host country welfare even though it increases migrant wages and lowers individual firm’s profits. We also demonstrate the existence of multiple equilibria: some countries have mostly temporary migration programs and see a low degree of cultural assimilation by the migrants, while other countries rely more on permanent migrants and see much more assimilation.
