Pointwise ergodic theorem for locally countable quasi-pmp graphs

We prove a pointwise ergodic theorem for quasi-probability-measure-preserving (quasi-pmp) locally countable measurable graphs, analogous to pointwise ergodic theorems for group actions, replacing the group with a Schreier graph of the action. For any quasi-pmp graph, the theorem gives an increasing sequence of Borel subgraphs with finite connected components along which the averages of $L^1$ functions converge to their expectations. Equivalently, it states that any (not necessarily pmp) locally countable Borel graph on a standard probability space contains an ergodic hyperfinite subgraph. The pmp version of this theorem was first proven by R. Tucker-Drob using probabilistic methods. Our proof is different: it is descriptive set theoretic and applies more generally to quasi-pmp graphs. Among other things, it involves introducing a graph invariant, a method of producing finite equivalence subrelations with large domain, and a simple method of exploiting nonamenability of a measured graph. The non-pmp setting additionally requires a new gadget for analyzing the interplay between the underlying cocycle and the graph.
Respiration rate of Golden papaya stored under refrigeration and with different controlled atmospheres

Knowledge of the respiration rate during the storage is important in the evaluation of the post-harvest tools that preserve fruit quality, and also for the provision of information for the development of new packages. This work aimed to evaluate the respiration rate of 'Golden' Carica papaya stored under refrigeration and controlled atmosphere conditions. The fruit was kept at 13 °C in controlled atmospheres comprising three levels of O2 (20.8 %, 6 %, 3 %) with a minimum level of CO2 (0.1 %); and three levels of CO2 (0.1 %, 6 %, 12 %) with the lowest level of O2 (3 %). Measurements were taken at intervals of 5 days during the 30 days of storage. The mass loss and the peel color of the fruits were identified at the end of the storage period. The fruit maintained under 'normal' atmosphere conditions (20.8 % O2 and 0.1 % CO2) increased its respiration rate after the 10th day, reaching after 30 days 4.3 times the initial value. After 30 days in 3 % O2, the respiration rate was 2.9 times less than in the normal atmosphere. The decrease in respiration rate minimized the mass loss in fruit stored at 3 % O2, but it was unaffected by increasing levels of CO2.
Anionen-Screening mit Infrarotspektreskopie : ein universelles Verfahren für die Wasseranalyse

Anionen-Screening mit Infrarotspektroskopie ein universelles Verfahren für die Wasseranalyse. Die quantitative Bestimmung von Wasserinhaltsstoffen mit Ionenchromatografie und UV/VIS-Spektroskopie ist seit Jahrzehnten eingeführt. Leistungsfähige GC/MS-Kopplungsmethoden haben die quantitative IR-Spektroskopie in Nischenanwendungen gedrängt. Dabei bieten sich FTIRSensoren sogar für das qualitative Screening von Salzfrachten an – wie unsere Untersuchungen für anorganische Anionen wie Carbonat, Hydrogencarbonat, Nitrat, Sulfat, Phosphat, Chromat und Borat zeigen. Die Nachweisgrenzen liegen unter 0,01– 0,03 mol/l. Die Methode eignet sich auch für Silicate und Arsenate.
Self-Regulatory Processes During Computer Skill Acquisition : Goal and Self-Evaluative Influences

In the studies reported in this article we examined the influence of learning goals and self-evaluation on college students' achievement outcomes during computer skill learning. Our conceptual focus was social cognitive theory, which postulates a critical role for self-regulation (Bandura, 1991a, 1991b; Zimmerman, 1998). Self-regulation refers to self-generated thoughts, feelings, and actions that are planned and cyclically adapted to attain personal goals (Zimmerman, 1989).

Se analiza como se guia a un grupo de escolares en una institucion publica de educacion especial; centrando la mirada en las interacciones conversacionales del debate y preguntandonos que patrones contribuyen mas eficazmente a sus aprendizajes.
A Latent Instrumental Variables Approach to Modeling Keyword Conversion in Paid Search Advertising

The authors present a modeling approach to assess the purchase conversion performance of individual keywords in paid search advertising. The model facilitates estimation of daily keyword conversion and click-through rates in a sparse data environment while accounting for the endogenous position of the text advertisement served in response to a search. Position endogeneity in paid search data can arise from both omitted variables and measurement error. The authors propose a latent instrumental variable approach to address this problem. They estimate their model on keyword-level paid search data containing daily information on impressions, clicks, and reservations for a major lodging chain. They find that higher positions increase both the click-through and conversion rates. When advertisements are served in higher positions, approximately one-third of new conversions is due to increased click-through while approximately two-thirds are due to increased conversion rates. The authors show that the keyword list generated on the basis of their estimated conversion rates outperforms the status quo list as well as lists generated by observed conversion and click-through rates.
Author's response to reviews Title:Increased CCL19 and CCL21 levels promote fibroblast ossification in ankylosing spondylitis hip ligament tissue Authors:

Introduction: It is well-documented that both chemokine (C-C motif) ligand 19 (C CL19) and 21 (CCL21) mediate cell migration and angiogenesis in many diseases. However, these ligands’ precise pathological role in ankylosing spondylitis (AS) has not been elucidated. The objective of this study was to examine the expression of CCL19 and CCL21 (CCL19/CCL21) in AS hip ligament tissue (LT) and determine their pathologi cal functions. Methods: The expression levels of CCL19, CCL21 and their receptor CCR7 in AS (n=31) and osteoarthritis (OA, n=21) LT were analyzed via real-time polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC). The expression of CCL19, CCL21 and CCR7 in AS ligament fibroblasts was also detected. The proliferation of ligament fibroblasts was measured via a cell counting kit-8 (CCK8) assay after exogenous CCL19/CCL21 tr eatment. Additionally, the role of CCL19/CCL21 in osteogenesis was evaluat ed via RT-PCR and enzyme-linked immunosorbent assay (ELISA) in individual AS fibroblas t cultures. Furthermore, the expression of the bone markers alkaline phosphatase (A LP), osteocalcin (OCN), collagenase I (COL1), integrin-binding sialoprotein (IBSP ) and the key regulators runt-related transcription factor-2 (Runx-2) and osterix were inves tigated. Moreover, the CCL19/CCL21 levels in serum and LT were measured via ELISA. Results: The mRNA levels of CCL19/CCL21 in AS hip LT were significantly higher than that in OA LT, and IHC analysis revealed a similar result . Exogenous CCL19/CCL21 treatment did not affect the proliferation of ligament fibroblasts but significantly up-regulated the expression of bone markers, including ALP and OCN, and the key regulators Runx-2 and osterix. In addition, the serum levels of CCL19/C CL21 were apparently elevated in AS patients compared to healthy controls (HC ), and the expression of the two chemokines correlated significantly in AS patients. Conclusions: CCL19 and CCL21, two chemokines displaying significantly associat ed expression in serum, indicating a synergistic effect on AS pathog enesis, may function as promoters of ligament ossification in AS patients.
Studying the Expression Patterns of OCT4 and SOX2 Proteins in Regenerating Rabbit Ear Tissue

Epimorphic regeneration in New Zealand rabbit ear is an interesting example of mammalian wound healing in which blastema formation is involved in replacement of injured tissues. It has been suggested that isolated cells from regenerating rabbit ear possess stem-like properties. In this study, we aimed to determine the expression of stemness markers, OCT4 and SOX2 proteins, in regenerating rabbit tissues by immunohistochemistry. Results indicated that both proteins could be detected in epithelial cells, hair follicle cells and perichondrium cells. Expression pattern analysis of OCT4 and SOX2 proteins showed no clear differences between regenerative and non-regenerative control tissues. According to several reports of OCT4 and SOX2 proteins expression in adult stem cells, it could be proposed that OCT4 and SOX2 expressing cells in regenerating rabbit ear tissues are progenitor/adult stem cells which are resident in these tissues, and other markers should be used for detection of blastema cells.

Relevance Feedback within CBIR Systems

— We present here the results for a comparative study of some techniques, available in the literature, related to the relevance feedback mechanism in the case of a short-term learning. Only one method among those considered here is belonging to the data mining field which is the K-nearest neighbors algorithm (KNN) while the rest of the methods is related purely to the information retrieval field and they fall under the purview of the following three major axes: Shifting query, Feature Weighting and the optimization of the parameters of similarity metric. As a contribution, and in addition to the comparative purpose, we propose a new version of the KNN algorithm referred to as an incremental KNN which is distinct from the original version in the sense that besides the influence of the seeds, the rate of the actual target image is influenced also by the images already rated. The results presented here have been obtained after experiments conducted on the Wang database for one iteration and utilizing color moments on the RGB space. This compact descriptor, Color Moments, is adequate for the efficiency purposes needed in the case of interactive systems. The results obtained allow us to claim that the proposed algorithm proves good results; it even outperforms a wide range of techniques available in the literature.
Indiscretions: at the intersection of queer and postcolonial theory

In the West, once apparently progressive causes such as sexual equality and lesbian and gay emancipation are increasingly redeployed in order to discipline and ostracize immigrant underclass subjects, primarily Muslims. Gender and sexuality on the one hand and race, culture, and/or ethnicity on the other are more and more forced into separate, mutually exclusive realms. That development cannot but bear on the establishment of queer and postcolonial studies as separate academic specializations, among whom relations usually are as cordial as they are indifferent. This volume inquires into the possibilities and limitations of a parceling out of objects alternative to the common scheme, crude but often apposite, in which Western sexual subjectivity is analyzed and criticized by queer theory, while postcolonial studies takes care of non-Western racial subjectivity. Sex, race: always already distinguished, yet never quite apart. Roderick A. Ferguson has described liberal pluralism as an "ideology of discreteness" in that it disavows race, gender and sexuality's mutually formative role in political, social, and economic relations. It is in that spirit that this volume advocates the discreet, hence judicious and circumspect, reconsideration of the (in)discrete realities of race and sex.

For All Time狗狗的邮票情缘

The Conference of Mayors tracks long-term trends in local water and sewer utility infrastructure and finances because continuity of utility services provided by the City are critical to protect public health, environmental quality and the economic base of communities. Annual Census reports provide financial information on expenditures and revenues that taken together offer a national aggregate measure of local utility infrastructure investment and budget performance. This report examines several financial aspects of public utility expenditures and revenues over the period 1993 to the recently released Census data for 2020. Widespread concern over the 2020 pandemic, a national unemployment spike from under 4% in 2019 to 8.1%, and travel restrictions caused budget planners to reconsider impacts that could reduce both expenditures and revenues – that didn’t happen. Contrary to those concerns, both expenditures and revenues increased in 2020 rather than decreased. The 2020 financial data for local utilities does not yet fully reflect impacts of the first year of pandemic related restrictions, but does reflect historic levels of financial support for families and businesses that rely on local utilities in the $2.2 trillion Coronavirus Aid, Relief, and Economic Security (CARES) Act, and that made a fiscal difference for local utilities.

A Perceptual Object Based Attention Mechanism for Scene Analysis

The object-based selective attention has been given increasingly importance in psychology domain in recent years,whereas most of the existing models of selective attention in computer vision field are either feature-based or space-based.In this paper,an object-based computational model of selective attention is proposed where "perceptual object" is postulated as the basic attention unit.The proposed attention model consists of following two steps:(1) how to select the first focus of attention in a given image;(2) how to shift the attention within the whole image.Under this model,the contrast,defined as the absolute gray difference between the "perceptual object" and its neighborhood,is used as the measure of the object's salience,by which the attention is determined and shifted.The advantages of this model lie in: Firstly,the model is entirely based on perceptual objects,its results can be easily applied to object detection,image segmentation,and scene analysis.Secondly,the model is of multi-scale,flexible enough to be easily adjusted according to the specific applications.Extensive experiments on real images show that the proposed attention model works reasonably.
Enough Is Enough! Or Is It? Factors That Impact Switching Intentions in Extended Service Transactions

In this paper we propose interrelationships between length of core service failure, time of core service failure, and satisfaction with service recovery efforts. These inter-relationships are hypothesized to impact customers’ decisions to dissolve a service relationship. We find that as the length of the core service delay increases and as that delay occurs later in the extended service transaction, satisfactory recovery efforts are less likely to negate subsequent switching intentions. We also examine the components of recovery satisfaction, and how the impact of those components may vary in the case of extended service transactions. Compensation and service provider apology are found to have a greater impact on customer satisfaction than organizational initiation or response speed.
ELECTRICAL STIMULATION OF THE SUBTHALAMIC NUCLEUS IN ADVANCED PARKINSON’S DISEASE ELECTRICAL STIMULATION OF THE SUBTHALAMIC NUCLEUS IN ADVANCED PARKINSON’S DISEASE

A BSTRACT Background In many patients with idiopathic Parkinson’s disease, treatment with levodopa is complicated by fluctuations between an “off” period (also referred to as “off medication”), when the medication is not working and the motor symptoms of parkinsonism are present, and an “on” period, when the medication is causing improved mobility (also referred to as “on medication”), often accompanied by debilitating dyskinesias. In animal models of Parkinson’s disease, there is overactivity in the subthalamic nucleus, and electrical stimulation of the subthalamic nucleus improves parkinsonism. We therefore sought to determine the efficacy and safety of electrical stimulation of the subthalamic nucleus in patients with Parkinson’s disease. Methods We studied 24 patients with idiopathic Parkinson’s disease in whom electrodes were implanted bilaterally in the subthalamic nucleus under stereotactic guidance with imaging and electrophysiologic testing of the location. Twenty were followed for at least 12 months. Clinical evaluations included the Unified Parkinson’s Disease Rating Scale, a dyskinesia scale, and timed tests conducted before and after surgery, when patients were off and on medications. Results After one year of electrical stimulation of the subthalamic nucleus, the patients’ scores for activities of daily living and motor examination scores (Unified Parkinson’s Disease Rating Scale parts II and III, respectively) off medication improved by 60 percent (P<0.001). The subscores improved for limb akinesia, rigidity, tremor, and gait. In the testing done on medication, the scores on part III improved by 10 percent (P<0.005). The mean dose of dopaminergic drugs was reduced by half. The cognitive-performance scores remained unchanged, but one patient had paralysis and aphasia after an intracerebral hematoma during the implantation procedure. Conclusions Electrical stimulation of the subthalamic nucleus is an effective treatment for advanced Parkinson’s disease. The severity of symptoms off medication decreases, and the dose of levodopa can be reduced, with a consequent reduction in dyskinesias. (N Engl J Med 1998;339:1105-11.)

Prisoner Disenfranchisement: Prisoner and Public Views of an Invisible Punishment

A prison sentence is often geared toward punishment of offenders, reduction of crime, and/or protection of the public. However, in many jurisdictions, those in prison may suffer from collateral or “invisible” consequences such as denial of their voting rights. Despite the growing global social and legal debates on prisoner disenfranchisement policy, there have been few empirical studies of this issue. We explored and compared a sample of the prisoners’ and the public's views of prisoner disenfranchisement policy in the United Kingdom. Although the public were more likely than prisoners to consider voting as important, they were less aware of prisoner disenfranchisement. A high proportion of prisoners said they would vote in prison, however, only a third had voted in the past (outside prison). Prisoners and the public held different attitudes toward prisoner disenfranchisement, and the public were more likely to view this policy as fair. Prisoners were more likely to believe that their vote could influence elections, and this best predicted their intentions to vote. These findings are further considered in relation to political party affiliation, prisoner populations, and offense types. We identify future directions for research on prisoner disenfranchisement.
