Occupational Mobility among Returned Migrants in Latin America: A Comparative Analysis

This article draws on data from the Mexican Migration Project and the Latin American Migration Project to study patterns of occupational mobility among male migrant household heads who have returned from the United States to Mexico, Costa Rica, Guatemala, and Puerto Rico. In general, migration to the United States increases the likelihood of upward mobility relative to nonmigrants if it begins at a relatively young age (before twenty-five), particularly in Costa Rica and Guatemala, where mobility is generally more fluid. In all countries, but especially Mexico, mobility prospects depend on a migrant’s own characteristics and the characteristics of the U.S. trip, as well the context of return. Education generally enhances occupational achievement upon return, as does greater U.S. experience and the holding of a nonmanual U.S. job, but taking more trips and having legal U.S. documents are generally associated with lower odds of occupational achievement at home.
On the fly signatures based on factoring

In response to the current need for fast, secure and cheap public-key cryptography largely induced by the fast development of electronic commerce, we propose a new on the fly signature scheme, i.e. a scheme that requires very small on-line work for the signer It combines provable security based on the factorization problem, short public and secret keys, short transmission and minimal on-line computation. It is the first RSA-like signature scheme that can be used for both efficient and secure applications based on low cost or contactless smart cards.
Priming from the Attentional Blink: A Failure to Extract Visual Tokens but Not Visual Types

When people must detect several targets in a very rapid stream of successive visual events at the same location, detection of an initial target induces misses for subsequent targets within a brief period. This attentional blink may serve to prevent interruption of ongoing target processing by temporarily suppressing vision for subsequent stimuli. We examined the level at which the internal blink operates, specifically, whether it prevents early visual processing or prevents quite substantial processing from reaching awareness. Our data support the latter view. We observed priming from missed letter targets, benefiting detection of a subsequent target with the same identity but a different case. In a second study, we observed semantic priming from word targets that were missed during the blink. These results demonstrate that attentional gating within the blink operates only after substantial stimulus processing has already taken place. The results are discussed in terms of two forms of visual representation, namely, types and tokens.
NBER WORKING PAPER SERIES HOUSEHOLD LEVERAGING AND DELEVERAGING

U.S. households' debt skyrocketed between 2000 and 2007, and has been falling since. This leveraging (and deleveraging) cycle cannot be accounted for by the liberalization, and subsequent tightening, of credit standards in mortgage markets observed during the same period. We base this conclusion on a quantitative dynamic general equilibrium model calibrated using macroeconomic aggregates and microeconomic data from the Survey of Consumer Finances. From the perspective of the model, the credit cycle is more likely due to factors that impacted house prices more directly, thus affecting the availability of credit through a collateral channel. In either case, the macroeconomic consequences of leveraging and deleveraging are relatively minor, because the responses of borrowers and lenders roughly wash out in the aggregate.

Efectos negativos de los deportes acuáticos en el asma

Asthma is a chronic disease that consists of inflammation of the airways. It causes coughs, chest pains and trouble breathing. Asthma still has no cure, but it is possible to control it. Although there are many studies that discuss the benefits of sports practice in asthmatic patients, this review article states that physical activity, depending on what is performed and the conditions under which it is performed, may have adverse effects for asthmatics. In fact, the practice of physical activity can cause asthma in itself, is the so-called exercise-induced asthma or EIA.
Examining the Mediating and Moderating Effects of Engagement and Conscientiousness for the Job Characteristics and Intention to Quit Relationship

Building on the job demands-resources, social exchange, and conservation of resources theories, the present study tests the relationship between job characteristics and intention to quit via work engagement as a mediator, and conscientiousness as a moderator. Based on data collected from a sample of Indian managers (N = 1302), we found that work engagement mediated the relationship between job characteristics and intention to quit. Moreover, personality trait of conscientiousness qualified job characteristics-intention to quit and work engagement-intention to quit relationships such that the negative effects of JC and work engagement on intention to quit were stronger for high conscientiousness than low. Implications for theory and practice are discussed.
Phase II Study of Gemcitabine and Vinorelbine Combination Chemotherapy in Patients With Non–Small-Cell Lung Cancer Not Responding to Previous Chemotherapy

Both gemcitabine and vinorelbine are new anticancer drugs that have shown activity in the treatment of chemonaïve non–small-cell lung cancer (NSCLC). Their role in the second-line treatment of NSCLC is less clear. We conducted a phase II study of gemcitabine and vinorelbine combination chemotherapy in patients with NSCLC who had not responded to previous platinum-based chemotherapy, to assess the response and toxicity of this regimen. Seventeen patients were enrolled from September 1998 to February 2001. Treatment consisted of vinorelbine 20 mg/m2 and gemcitabine 800 mg/m2 intravenous infusion on days 1, 8, and 15 every 4 weeks. Sixty-five cycles of treatment were given, with a median of four cycles. All patients were evaluable for the toxicity profile, and 16 patients were evaluable for the response rate. The major toxicity was myelosuppression. Grade III or IV neutropenia occurred in 9 patients (52.9%) during treatment. Febrile neutropenia occurred in only 1 patient (5.9%). Grade III anemia and thrombocytopenia occurred in two and three patients, respectively. Other toxicities were few and mild in severity. After 2 cycles of treatment, 5 of 16 patients (31.3%) had a partial response (95% CI 8.6–64%). The median time to disease progression was 4.6 months and the median survival was 8.3 months. The 1-year survival rate was 34.3%. In conclusion, gemcitabine and vinorelbine salvage chemotherapy produces a relatively high response rate, low toxicity profile, and good survival in Chinese patients with NSCLC who have not responded to previous platinum-based chemotherapy. Further study is needed to confirm its activity.
New Tools for Coronary Risk Assessment: What Are Their Advantages and Limitations?

The concept of risk assessment and reduction, introduced initially by the Framingham Heart Study and refined in other models, forms the cornerstone of preventive cardiology. Risk factor assessment determines the therapeutic strategy, because the intensity of preventive intervention is tailored to the patient’s risk of coronary heart disease. The conventional risk factors for coronary heart disease include elevated serum total cholesterol and LDL cholesterol, low HDL cholesterol, elevated blood pressure, cigarette smoking, diabetes, vascular disease, menopausal status (women only), and age. Aggressive risk factor reduction, formerly used exclusively in secondary prevention, may be pivotal to optimal patient management in high-risk primary prevention. A number of noninvasive imaging modalities have the potential to measure and to monitor atherosclerosis in asymptomatic individuals and include exercise ECG testing, electron beam computed tomography, magnetic resonance coronary angiography, positron emission tomography, ankle-brachial index, and B-mode ultrasound. Novel serum markers, including C-reactive protein and homocysteine, have the ability to gauge risk in the individual patient. Systemic therapy for risk reduction in primary prevention may be preferable to local therapy (eg, angioplasty and bypass) and may more effectively prevent acute coronary events than these more invasive approaches.
Cultivating Passion in Teaching English Language Learners: A Critical Analytical Inquiry.

In this theoretical dissertation my aim is to research the academic literature in the field of second language acquisition (SLA), compare it to the life experiences of past and/or present students, colleagues, children and myself to reflect and summarize my learning in the form of a conceptual framework that I have named, Framework for Understanding the Teaching and Learning of English Language Learners. The ever increasing number of diverse students in US schools along with the demand for standardized learning and assessments has created a range of challenges for educators that I seek to attend to with the writing of this dissertation. I use the terms second language learners (L2), English Language Learners (ELLs), diverse learners and linguistically and culturally diverse students interchangeably to conform to the terms appearing in the larger academic field of Second Language Acquisition (SLA) and to vary the academic discourse. These labels refer to students who know a language other than English at varied levels of proficiency; have prior knowledge dissimilar to that of the mainstream population and share differing cultural worldviews. My inquiry revolves around the question: How does Framework for Understanding the Teaching and Learning of English Language Learners, reflect current findings in SLA research to assist educators in making effectual instructional decisions when planning and delivering teaching for ELLs? I selected critical pedagogy for my
P y NP , and the quantum field computer

The central problem in computer science is the conjecture that two complexity classes, P (polynomial time) and NP (nondeterministic polynomial time—roughly those decision problems for which a proposed solution can be checked in polynomial time), are distinct in the standard Turing model of computation: P (cid:222) NP . As a generality, we propose that each physical theory supports computational models whose power is limited by the physical theory. It is well known that classical physics supports a multitude of implementation of the Turing machine. Non-Abelian topological quantum field theories exhibit the mathematical features necessary to support a model capable of solving all [ P problems, a computationally intractable class, in polynomial time. Specifically, Witten [Witten, E. (1989) Commun. Math. Phys. 121, 351–391] has identified expectation values in a certain SU (2)-field theory with values of the Jones polynomial [Jones, V. (1985) Bull. Am. Math. Soc. 12, 103–111] that are [ P -hard [Jaeger, F. , Vertigen, D. & Welsh, D. (1990) Math. Proc. Comb. Philos. Soc. 108, 35–53]. This suggests that some physical system whose effective Lagrangian contains a non-Abelian topological term might be manipulated to serve as an analog computer capable of solving NP or even [ P -hard problems in polynomial time. Defining such a system and addressing the accuracy issues inherent in preparation and measurement is a major unsolved problem. It
Clinical outcomes of ABO‐ and HLA‐incompatible kidney transplantation: a nationwide cohort study

This was a nationwide cohort study to investigate the impact of anti‐A/B and donor‐specific anti‐HLA (HLA‐DSA) antibodies on the clinical outcomes in kidney transplant recipients (KTRs). We classified a total of 1964 KTRs into four groups: transplants from ABO‐incompatible donors (ABOi, n = 248); transplants in recipients with HLA‐DSA (HLAi, n = 144); transplants from combined ABOi and HLAi donors (ABOi + HLAi, n = 31); and a control group for whom neither ABOi nor HLAi was applicable (CONT, n = 1541). We compared the incidence of biopsy‐proven acute rejection (BPAR), allograft and patient survival rates. The incidence of BPAR was higher in the HLAi and ABOi + HLAi groups relative to the CONT group; in contrast, it was not higher in the ABOi group. Death‐censored graft survival rates did not differ across the four groups. However, relative to the CONT group, patient survival rate was reduced in the ABOi and ABOi + HLAi groups, and with infection being the most common cause of death. Further, multivariable analysis revealed that desensitization therapy because of ABOi or HLAi was independent risk factors for patient mortality. HLAi was a more important risk factor for BPAR compared with ABOi. However, pretransplant desensitization therapy for either ABOi or HLAi significantly increased the risk of infection‐related mortality.
Commitment to Newspaper-TV Partnering: A Test of the Impact of Institutional Isomorphism

This study uses institutional theory from the study of organizations to explore the degree to which newspapers and TV stations pursue partnerships for concrete benefits, and the degree to which they pursue them to keep up with perceived trends in the industry. Findings from a national survey of newspaper and TV news managers revealed that availability of resources and the goal-oriented pursuit of concrete benefits best predict initiation of partnerships. However, strength of commitment to partnering correlated more strongly with institutional factors—i.e., managers' professional involvement and the level of partnering of nearby “flagship” news institutions and competitors. This was the case even when controlling for business factors such as competition, penetration, and public ownership.
Characterization of the Host Immune Response in Human Ganglia after Herpes Zoster

ABSTRACT Varicella-zoster virus (VZV) causes varicella (chicken pox) and establishes latency in ganglia, from where it reactivates to cause herpes zoster (shingles), which is often followed by postherpetic neuralgia (PHN), causing severe neuropathic pain that can last for years after the rash. Despite the major impact of herpes zoster and PHN on quality of life, the nature and kinetics of the virus-immune cell interactions that result in ganglion damage have not been defined. We obtained rare material consisting of seven sensory ganglia from three donors who had suffered from herpes zoster between 1 and 4.5 months before death but who had not died from herpes zoster. We performed immunostaining to investigate the site of VZV infection and to phenotype immune cells in these ganglia. VZV antigen was localized almost exclusively to neurons, and in at least one case it persisted long after resolution of the rash. The large immune infiltrate consisted of noncytolytic CD8+ T cells, with lesser numbers of CD4+ T cells, B cells, NK cells, and macrophages and no dendritic cells. VZV antigen-positive neurons did not express detectable major histocompatibility complex (MHC) class I, nor did CD8+ T cells surround infected neurons, suggesting that mechanisms of immune control may not be dependent on direct contact. This is the first report defining the nature of the immune response in ganglia following herpes zoster and provides evidence for persistence of non-latency-associated viral antigen and inflammation beyond rash resolution.
Legal Treatment of the Victim-Offender Relationship in Crimes of Violence

Prior theory and research indicate that the victim-offender relationship is an important factor in determining how an offender is treated at various stages of the criminal justice system, with stranger offenders faring worse than nonstranger offenders in all stages of legal processing. This study investigates whether the victim-offender relationship plays a role in determining the original charge, the crime conviction, and the sentence length of inmates in prison for violent crimes. Data consist of interview and official record information of 273 sentenced and incarcerated violent male offenders. The results indicate that the victim-offender relationship is related to the legal processing, but in paradoxical ways. Thus, although nonstranger offenders are charged with and convicted of more serious crimes, stranger offenders receive significantly longer sentences. Implications for policy and future research are discussed.
A Repeated Lie Becomes a Truth? The Effect of Intentional Control and Training on Deception

Deception has been demonstrated as a task that involves executive control such as conflict monitoring and response inhibition. In the present study, we investigated whether or not the controlled processes associated with deception could be trained to be more efficient. Forty-eight participants finished a reaction time-based differentiation of deception paradigm (DDP) task using self- and other-referential information on two occasions. After the first baseline DDP task, participants were randomly assigned to one of three groups: a control group in which participants finished the same task for a second time; an instruction group in which participants were instructed to speed up their deceptive responses in the second DDP; a training group in which participants received training in speeding up their deceptive responses, and then proceeded to the second DDP. Results showed that instruction alone significantly reduced the RTs associated with participants’ deceptive responses. However, the differences between deceptive and truthful responses were erased only in the training group. The result suggests that the performance associated with deception is malleable and could be voluntarily controlled with intention or training.
Two distinct metacommunities characterize the gut microbiota in Crohn's disease patients

Abstract The inflammatory intestinal disorder Crohn's disease (CD) has become a health challenge worldwide. The gut microbiota closely interacts with the host immune system, but its functional impact in CD is unclear. Except for studies on a small number of CD patients, analyses of the gut microbiota in CD have used 16S rDNA amplicon sequencing. Here we employed metagenomic shotgun sequencing to provide a detailed characterization of the compositional and functional features of the CD microbiota, comprising also unannotated bacteria, and investigated its modulation by exclusive enteral nutrition. Based on signature taxa, CD microbiotas clustered into 2 distinct metacommunities, indicating individual variability in CD microbiome structure. Metacommunity-specific functional shifts in CD showed enrichment in producers of the pro-inflammatory hexa-acylated lipopolysaccharide variant and a reduction in the potential to synthesize short-chain fatty acids. Disruption of ecological networks was evident in CD, coupled with reduction in growth rates of many bacterial species. Short-term exclusive enteral nutrition elicited limited impact on the overall composition of the CD microbiota, although functional changes occurred following treatment. The microbiotas in CD patients can be stratified into 2 distinct metacommunities, with the most severely perturbed metacommunity exhibiting functional potentials that deviate markedly from that of the healthy individuals, with possible implication in relation to CD pathogenesis.
Age, stratigraphy, sedimentology and tectonic setting of the Sigri Pyroclastic Formation and its fossil forests, Early Miocene, Lesbos, Greece

The Petrified Forest of Lesbos comprises silicified tree fossils at multiple stratigraphic levels within the Lower Miocene Sigri Pyroclastic Formation. Our objective was to understand the interplay of tectonic setting, structural evolution, volcanological setting and basin evolution in the preservation of this remarkable natural monument. Sections were logged for lithology, sedimentary structures and hydrothermal alteration. Orientations of fallen fossil trees were measured. Samples were taken for mineralogical and geochemical analysis. 40Ar/39Ar dating was carried out on mineral separates from four samples. Widespread andesite‐dacite domes, the Eressos Formation, intrude and overlie metamorphic basement and are overlain by the Sigri Pyroclastic Formation, which comprises several hundreds of metres of pyroclastic flow tuffs (unwelded ignimbrites) interbedded with fluvial conglomerate and volcaniclastic sandstone. The Sigri Pyroclastic Formation ranges in age from 21.5 to 22 Ma, where it overlies the lacustrine Gavathas Formation, to younger than 18.4 Ma. Tuffs and fluvial conglomerates in the Sigri Pyroclastic Formation coarsen eastwards, and petrified trees and soil horizons occur throughout the Formation. The recurrence of pyroclastic flows was approximately one every 20 ka, so destructive flows were relatively infrequent, allowing the development of climax vegetation between most eruptions. Conglomerate‐filled channels show that rivers flowed westwards. Tree fall directions indicate NW to N movement of pyroclastic flows, implying a source near the younger Mesotopos–Tavari caldera to the south. The basin, which formed in a NNE‐trending dextral strike‐slip regime, provided some topographic steering. Following the Sigri Pyroclastic Formation at ca. 18 Ma, there was a rapid increase in the pace of volcanic activity, with the eruption of thick lava sequences and welded ignimbrites, and intrusion of dykes and laccoliths in SW Lesbos. Rapid burial by permeable tuffs, silica from alteration of volcanic ash, and later hydrothermal circulation all contributed to the preservation of the petrified trees.
