The path to ethnogenesis and autonomy : Kallawaya-consciousness in plurinational Bolivia

The Path to Ethnogenesis and Autonomy: Kallawaya-consciousness in Plurinational Bolivia This thesis examines the construction of ethnic identity, autonomy and indigenous citizenship in plurinational Bolivia. In 2009, the Kallawayas, an Andean indigenous nation, took advantage of legislation in Bolivia’s new constitution to begin a process of legally constituting themselves as autonomous from the state. The objective of Indigenous Autonomy in the constitution is to allow indigenous nations and peoples to govern themselves according to their conceptions of ‘Living Well’. Living well, for the Kallawayas is understood in terms of what it means to be runa, a person living in the ayllu (the traditional Andean community). The Kallawayas are noted as healers, and sickness and health is understood as related to the maintenance of a ritual relationship of reciprocity with others in the ayllu, both living humans and ancestors, remembered in the landscape. Joint ritual relations with the landscape play an important role in joining disparate Kallawaya ayllus with distinct traditions and languages (Aymara, Quechua and the Kallawaya language Macha Jujay are spoken) together as an ethnic group. However, Kallawaya politics has followed the trajectory of national peasant politics in recent decades of splitting into federations divided along class and ethnic lines. The joint ritual practices which traditionally connected the Kallawaya ayllus adapted to reflect this new situation of division between three sections of Kallawaya society. This has meant that the Kallawayas are attempting political autonomy as an ethnic group when they have never been more fractured. This thesis then examines the meaning of autonomy and the Good Life for a politically divided and ethnically diverse indigenous people.
Recommendations for training in pediatric psychology: defining core competencies across training levels.

OBJECTIVE As a field, pediatric psychology has focused considerable efforts on the education and training of students and practitioners. Alongside a broader movement toward competency attainment in professional psychology and within the health professions, the Society of Pediatric Psychology commissioned a Task Force to establish core competencies in pediatric psychology and address the need for contemporary training recommendations. METHODS The Task Force adapted the framework proposed by the Competency Benchmarks Work Group on preparing psychologists for health service practice and defined competencies applicable across training levels ranging from initial practicum training to entry into the professional workforce in pediatric psychology. RESULTS Competencies within 6 cluster areas, including science, professionalism, interpersonal, application, education, and systems, and 1 crosscutting cluster, crosscutting knowledge competencies in pediatric psychology, are presented in this report. CONCLUSIONS Recommendations for the use of, and the further refinement of, these suggested competencies are discussed.
25-nm Gate Length nMOSFET With Steep Channel Profiles Utilizing Carbon-Doped Silicon Layers (A P-Type Dopant Confinement Layer)

Steep channel profiles of scaled transistors are a promising approach for advancing transistor generation in bulk complementary metal-oxide-semiconductor (MOS). In this paper, a carbon-doped Si (Si:C) layer under an undoped Si layer is proposed to form steep p-type channel profiles in n-channel MOS field-effect transistors (nMOSFETs) due to extremely low diffusivity of boron and indium in Si:C layers. This structure with low channel impurity improves mobility and suppresses threshold voltage (VTH) variation. Both items are essential for aggressively scaled MOSFETs with a gate length less than 25 nm. We demonstrated well-controlled, high-performance, and low VTH variability nMOSFETs with a Si:C-Si epitaxial channel structure.
Species distinction and evolutionary relationships of the Italian hare (Lepus corsicanus) as described by mitochondrial DNA sequencing

The taxonomic status of the Italian hare Lepus corsicanus has been uncertain since its first description by W. E. de Winton in 1898 (de Winton WE. Annual Magazine of Natural History, London, 1898, 1, 149–158). The distribution range of this species has shrunk severely over the last few decades owing to overhunting and restocking with nonindigenous brown hares (L. europaeus) in central and southern Italy and Sicily. Recently, scanty populations of Italian hares were rediscovered, and samples for morphological and molecular analyses were collected. Nucleotide sequences of the mitochondrial DNA (mtDNA) control region and cytochrome b indicate that L. corsicanus is a phylogenetically distinct species, which can be identified by concordant morphological and mtDNA traits. It seems to be reproductively isolated and apparently does not hybridize with sympatric brown hares. Phylogenetic analyses suggest that Italian and brown hares are not closely related sister taxa, but belong to distinct evolutionary lineages that dispersed in western Europe in different periods during the early Pleistocene. The Italian hare probably differentiated in isolated refuges in southern Italy during the last glaciation. Comparative analyses of mismatch distributions suggest that hares have had different demographic histories during the Pleistocene, which resulted in phylogeographical structuring in Italian hares, but not in brown and mountain (L. timidus) hares. The Italian hare is an endangered endemism and needs urgent conservation efforts.
An 808-nm Diode Laser with a Flat-Top Handpiece Positively Photobiomodulates Mitochondria Activities.

OBJECTIVE Photobiomodulation is proposed as a non-linear process. Only the action of light at a low intensity and fluence is assumed to have stimulation on cells; whereas a higher light intensity and fluence generates negative effects, exhausting the cell's energy reserve as a consequence of a too strong stimulation. In our work, we detected the photobiomodulatory effect of an 808-nm higher-fluence diode laser [64 J/cm2-1 W, continuous wave (CW)] irradiated by a flat-top handpiece on mitochondria activities, such as oxygen consumption, activity of mitochondria complexes I, II, III, and IV, and cytochrome c as well as ATP synthesis. MATERIALS AND METHODS The experiments are performed by standard procedure on mitochondria purified from bovine liver. RESULTS Our higher-fluence diode laser positively photobiomodulates the mitochondria oxygen consumption, the activity of the complexes III and IV, and the ATP production, with a P/O = 2.6. The other activities are not influenced. CONCLUSION Our data show for the first time that even the higher fluences (64 J/cm2-1 W), similar to the low fluences, can photobiostimulate the mitochondria respiratory chain without uncoupling them and can induce an increment in the ATP production. These results suggest that the negative effects of higher fluences observed to date are not unequivocally due to higher fluence per se but might be a consequence of the irradiation carried by handpieces with a Gaussian profile.
Case Report: Standardizing Laboratory Data by Mapping to LOINC

The authors describe a pilot project to standardize local laboratory data at five Indian Health Service (IHS) medical facilities by mapping laboratory test names to Logical Observation Identifier Names and Codes (LOINC). An automated mapping tool was developed to assign LOINC codes. At these sites, they were able to map from 63% to 76% of the local active laboratory tests to LOINC using the mapping tool. Eleven percent to 27% of the tests were mapped manually. They could not assign LOINC codes to 6% to 19% of the laboratory tests due to incomplete or incorrect information about these tests. The results achieved approximate other similar efforts. Mapping of laboratory test names to LOINC codes will allow IHS to aggregate laboratory data more easily for disease surveillance and clinical and administrative reporting efforts. This project may provide a model for standardization efforts in other health systems.
Aperiodic Sampled-Data Sliding-Mode Control of Fuzzy Systems With Communication Delays Via the Event-Triggered Method

This paper studies the aperiodic sampled-data control for the sliding-mode control (SMC) scheme of fuzzy systems with communication-induced delays via the event-triggered method. In practice, it is impossible to update control in continuous manner; thus, an event-based control technique has become popular with the advantage that the control task is executed only if it is triggered by an event. In this paper, the event-based sliding-mode control (ESMC) is designed for each linear subsystem of the global fuzzy model first. Then, the conditions for “fuzzily” amalgamated ESMC are discussed to stabilize the global fuzzy model. This ensures that the SMC is executed only when necessary. Furthermore, the results are extended to the fuzzy systems with communication-induced delays. Finally, case studies are carried out to demonstrate the effectiveness of the derived results.
A Credit Portfolio Framework Under Dependent Risk Parameters: Probability of Default, Loss Given Default and Exposure at Default

This paper introduces a credit portfolio framework that allows for dependencies between default probabilities, secured and unsecured recovery rates and exposures at default (EADs). The overall approach is an extension of the factor models of Pykhtin (2003) and Miu and Ozdemir (2006), with respect to differentiated recovery rates and the inclusion of dependent exposures. As there is empirical evidence for dependence between these risk parameters and observations for the EAD, and since the secured and unsecured recovery rates are available only in the case of a default, we propose a multivariate extension of the selection model of Heckman in order to estimate the unknown parameters within a maximum likelihood framework. Finally, we empirically demonstrate the effects of the dependence structure on the portfolio loss distribution and its risk measure for a hypothetical loan portfolio.
Tune in to the Tone: Lexical Tone Identification is Associated with Vocabulary and Word Recognition Abilities in Young Chinese Children

Lexical tone is one of the most prominent features in the phonological representation of words in Chinese. However, little, if any, research to date has directly evaluated how young Chinese children’s lexical tone identification skills contribute to vocabulary acquisition and character recognition. The present study distinguished lexical tones from segmental phonological awareness and morphological awareness in order to estimate the unique contribution of lexical tone in early vocabulary acquisition and character recognition. A sample of 199 Cantonese children aged 5–6 years was assessed on measures of lexical tone identification, segmental phonological awareness, morphological awareness, nonverbal ability, vocabulary knowledge, and Chinese character recognition. It was found that lexical tone awareness and morphological awareness were both associated with vocabulary knowledge and character recognition. However, there was a significant relationship between lexical tone awareness and both vocabulary knowledge and character recognition, even after controlling for the effects of age, nonverbal ability, segmental phonological awareness and morphological awareness. These findings suggest that lexical tone is a key factor accounting for individual variance in young children’s lexical acquisition in Chinese, and that lexical tone should be considered in understanding how children learn new Chinese vocabulary words, in either oral or written forms.
Tandem affinity purification of the Candida albicans septin protein complex

A novel vector was constructed to enable the integrative marking of individual genes and the affinity purification of interacting molecules within protein complexes from Candida albicans using a tandem 6×histidine and FLAG epitope tag. The system was verified by purifying the C. albicans septin complex (a self‐associating complex of cytoskeletal proteins) from both yeast and hyphal cells. One‐step affinity purification was insufficient for purification of the protein complex, whereas tandem affinity purification (TAP) gave an extensively purified protein complex with a very low background. Electrophoretic and mass spectrometry analysis showed that the affinity‐purified C. albicans septin complex, which comprises predominantly CaCdc3p, CaCdc10p, CaCdc11p, CaCdc12p and CaSep7p, was not affected by cell morphology. The purified septin complex appeared to have a stoichiometry of 2 CaCdc3p, 1–2 CaCdc10p, 1 CaCdc11p, 2 CaCdc12p and ≤1 CaSep7p. The successful application of TAP to the purification and analysis of the C. albicans septin complex indicates that this technology will have much wider application to proteomic studies of this pathogenic fungus.

On the influence of the U.S. monetary policy on the crude oil price volatility

Modeling crude oil volatility is of substantial interest for both energy researchers and policy makers. This paper aims to investigate the impact of the U.S. monetary policy on crude oil future price (COFP) volatility. By means of the recently proposed generalized autoregressive conditional hetroskedasticity mixed data sampling (GARCH-MIDAS) model, a proxy of the U.S. monetary policy is included into the COFP volatility equation, alongside with other macroeconomic determinants. Strong evidence that an expansionary monetary policy is associated with an increase of the COFP volatility is found. In particular, an expansionary (restrictive) variation in monetary policy anticipates a positive (negative) variation in COFP volatility. Furthermore, an out of sample forecasting procedure shows that the estimated GARCH-MIDAS model has a superior predictive ability with respect to that of the GARCH(1,1), when the U.S. monetary policy exhibits severe changes in the run-up period.
Corporate Finance and Monetary Policy

We develop a general equilibrium model where entrepreneurs finance random investment opportunities using trade credit, bank-issued assets, or currency. They search for bank funding in over-the-counter markets where loan sizes, interest rates, and down payments are negotiated bilaterally. The theory generates pass-through from nominal interest rates to real lending rates depending on market microstructure, policy, and firm characteristics. Higher banks' bargaining power, for example, raises pass-through but weakens transmission to investment. Interest rate spreads arise from liquidity, regulatory, and intermediation premia and depend on policy described as money growth or open market operations.
Dialysis‐Dependent Changes in Ventricular Repolarization

Background: Epidemiological data suggest increased risk of sudden death during and immediately after hemodialysis. Microvolt T‐wave alternans (mTWA) is an electrocardiogram (ECG) measure of abnormal ventricular repolarization, which can be used in sudden death risk stratification. The aim of this study was to determine whether mTWA measurements during dialysis indicate abnormal repolarization as a potential trigger to dialysis associated arrhythmias.
Akt induces enhanced myocardial contractility and cell size in vivo in transgenic mice

The serine-threonine kinase Akt seems to be central in mediating stimuli from different classes of receptors. In fact, both IGF-1 and IL6-like cytokines induce hypertrophic and antiapoptotic signals in cardiomyocytes through PI3K-dependent Akt activation. More recently, it was shown that Akt is involved also in the hypertrophic and antiapoptotic effects of β-adrenergic stimulation. Thus, to determine the effects of Akt on cardiac function in vivo, we generated a model of cardiac-specific Akt overexpression in mice. Transgenic mice were generated by using the E40K, constitutively active mutant of Akt linked to the rat α-myosin heavy chain promoter. The effects of cardiac-selective Akt overexpression were studied by echocardiography, cardiac catheterization, histological and biochemical techniques. We found that Akt overexpression produced cardiac hypertrophy at the molecular and histological levels, with a significant increase in cardiomyocyte cell size and concentric LV hypertrophy. Akt-transgenic mice also showed a remarkable increase in cardiac contractility compared with wild-type controls as demonstrated by the analysis of left ventricular (dP/dtmax) in an invasive hemodynamic study, although with graded dobutamine infusion, the maximum response was not different from that in controls. Diastolic function, evaluated by left ventricular dP/dtmin, was not affected at rest but was impaired during graded dobutamine infusion. Isoproterenol-induced cAMP levels, β-adrenergic receptor (β-AR) density, and β-AR affinity were not altered compared with control mice. Moreover, studies on signaling pathway activation from myocardial extracts demonstrated that glycogen synthase kinase3-β is phosphorylated, whereas p42/44 mitogen-activated protein kinases is not, indicating that Akt induces hypertrophy in vivo by activating the glycogen synthase kinase3-β/GATA 4 pathway. In summary, our results not only demonstrate that Akt regulates cardiomyocyte cell size in vivo, but, importantly, show that Akt modulates cardiac contractility in vivo without directly affecting β-AR signaling capacity.
The Association between Objectively Measured Neighborhood Features and Walking in Middle-Aged Adults

Purpose. Explore the role of the neighborhood environment in supporting walking. Design. Cross-sectional study of 10,286 residents of 200 neighborhoods. Participants were selected using a stratified two-stage cluster design. Data were collected by mail survey (68.5% response rate). Setting. Brisbane City Local Government Area, Australia, 2007. Subjects. Brisbane residents aged 40 to 65 years. Measures. Environmental: street connectivity, residential density, hilliness, tree coverage, bikeways, and streetlights within a 1-km circular buffer from each resident's home; and network distance to nearest river or coast, public transport, shop, and park. Walking: minutes walked in the previous week: <30 minutes, ≥30 to <90 minutes, ≥90 to <150 minutes, ≥150 to <300 minutes, and ≥300 minutes. Analysis. The association between each neighborhood characteristic and walking was examined using multilevel multinomial logistic regression, and the model parameters were estimated using Markov chain Monte Carlo simulation. Results. After adjustment for individual factors, the likelihood of walking for more than 300 minutes (relative to <30 minutes) was highest in areas with the most connectivity (odds ratio [OR] = 1.93; 99% confidence intervals [CI], 1.32–2.80), greatest residential density (OR = 1.47; 99% CI, 1.02–2.12), least tree coverage (OR = 1.69; 99% CI, 1.13–2.51), most bikeways (OR = 1.60; 99% CI, 1.16–2.21), and most streetlights (OR = 1.50; 99% CI, 1.07–2.11). The likelihood of walking for more than 300 minutes was also higher among those who lived closest to a river or the coast (OR = 2.06; 99% CI, 1.41–3.02). Conclusion. The likelihood of meeting (and exceeding) physical activity recommendations on the basis of walking was higher in neighborhoods with greater street connectivity and residential density, more streetlights and bikeways, closer proximity to waterways, and less tree coverage. Interventions targeting these neighborhood characteristics may lead to improved environmental quality as well as lower rates of overweight and obesity and associated chromic disease.

A Clinicopathological Study of Seven Cases of Primary High-Grade Malignant Non-Hodgkin's Lymphoma of the Central Nervous System

Seven cases of primary non-Hodgkin's lymphomas of the central nervous system are described. Six cases were diagnosed after pathologic examination of surgical material; in one case, a patient with acquired immunodeficiency syndrome, the diagnosis was made at autopsy. The mean age of the patients was 52 years. The lesions were supratentorial in all cases, and unifocal in 6: the autopsy case had multicentric lesions. The cytologic examination of the cerebrospinal fluid was performed in 3 cases and was negative. The most common histologic type was immunoblastic lymphoma. The mean postoperative survival time was 12 months; in 2 cases, surgery combined with radiotherapy prolonged the survival for more than 2 years. Leptomeningeal involvement was considered to indicate a poor prognosis.
Progeny of Olig2-Expressing Progenitors in the Gray and White Matter of the Adult Mouse Cerebral Cortex

Despite their abundance, still little is known about the rather frequent, constantly proliferating progenitors spread throughout the adult mouse brain parenchyma. The majority of these progenitors express the basic-helix-loop-helix transcription factor Olig2, and their number further increases after injury. Here, we examine the progeny of this progenitor population by genetic fate mapping using tamoxifen-inducible Cre-recombination in the Olig2 locus to turn on permanent reporter gene expression in the adult brain. Consistent with Olig2 expression in proliferating NG2+ progenitors, most reporter+ cells seen shortly after initiating recombination at adult stages incorporated BrdU and contained the proteoglycan NG2 in both the gray (GM) and the white matter (WM) of the cerebral cortex. However, at longer time points after induction, we observed profound differences in the identity of reporter+ cells in the WM and GM. Whereas most of the Olig2+ progenitors had generated mature, myelinating oligodendrocytes in the WM, hardly any reporter+ cells showing mature oligodendrocyte characteristics were detectable even up to 6 months after recombination in the GM. In the GM, most reporter+ cells remained NG2+, even after injury, but stopped proliferating rather soon after recombination. Thus, our results demonstrate the continuous generation of mature, myelinating oligodendrocytes in the WM, whereas cells in the GM generated mostly postmitotic NG2+ glia.
Liquidity commonality in order-driven trading: evidence from the Athens Stock Exchange

ABSTRACT We examine the presence of liquidity commonality in the order-driven Athens Stock Exchange (ASE). Unlike the majority of liquidity commonality studies that focus on the bid–ask spread, our analysis extends deeper in the Limit Order Book, providing insight on the price impact of both small and large trades. We utilize a 6-month FTSE/ATHEX-20 intraday data set to estimate the liquidity factor model of Chordia et al. (2000). To this end, we conduct single-equation analysis as well as panel data analysis with the use of two-way clustered errors, correcting for simultaneous firm and time correlations. Moreover, we apply standard principal component analysis on stock liquidities to extract the marketwide liquidity component. We find that liquidity commonality is low at the bid–ask spread, whereas it increases deeper in the book; consequently, large traders face liquidity risks associated with both individual stock and marketwide illiquidity. Moreover, our empirical evidence hints that liquidity commonality is asynchronous, suggesting that the ASE trading process includes various levels of information speed. Our analysis contributes to the understanding of liquidity commonality in order-driven trading, especially in emerging markets like the ASE where trading activity is limited and information speed is low.
