Independent clamps of peripheral and central temperatures and their effects on heat production in the goat.

1. Experiments were performed to study the interaction of skin and core temperatures in the control of heat production. Shorn goats with intravascular heat exchangers to control core temperature were immersed to the neck in a circulating water bath to clamp skin temperature. With bath temperature kept constant at levels between 32 and 42 degrees C, core temperature was varied between 40 and 36 degrees C, and the changes in heat production were measured. 2. With falling core temperature shivering occurred at all bath temperatures, and heat production rose. The threshold of core temperature below which heat production increased varied inversely to the level of skin temperature. Even at a bath temperature of 42 degrees C the slope at which heat production rose exceeded ‐5 W. kg‐1 . C‐1. The results show that in the goat even very high skin temperatures do not abolish the central impulse to shiver which is caused by low core temperature. 3. It is concluded that in the control of heat production, skin temperature and core temperature provide linear and independent inputs which do not replicate any known relationship between temperature and discharge frequency of thermoreceptors.
Una Epistemología Pluralista

El anarquismo epistemologico posee una doble dimension: metodologico-epistemologica y etica-politica. Consecuencia de lo primero es que no existen reglas definitivas ni leyes universales que orienten la practica cientifica, y junto con ello la aceptacion de la concurrencia de elementos no racionales y extra-cientificos en la construccion del conocimiento cientifico. La segunda va en contra de los conceptos universales que devienen totalitarios y excluyentes, lo que traera como consecuencia la apertura a nuevas perspectivas y explicaciones de mundo posibles.
The complex determinants of school intake characteristics and segregation, England 1989 to 2014

The extent of between-school segregation, or clustering of disadvantaged students within schools, in England varies depending on the indicator of interest. For example, the trend over time for segregation by student poverty differs from those for ethnicity or special educational need. Additionally the causes of the level of segregation for any indicator will be different from the causes of changes in that level over time. This new paper uses data for all state-funded schools in England from 1989 to 2014 to identify the possible determinants of segregation. The results are summarised for England and its economic regions, and presented in more detail for local authority areas. The long-term underlying level of segregation of each indicator appears to be the outcome of structural and local geographic factors. However, the annual changes in segregation for most indicators can be explained most simply by changes in the prevalence of each indicator. For example, the UK policy of inclusion has considerably increased the number of students with statements of special needs in mainstream schools, and this has resulted, intentionally, in less segregation in terms of this indicator. Segregation by poverty varies at least partly with the economic cycle. Some of the explanatory factors, such as the global economy or the prevalence of specific ethnic minority groups, are not directly under policy-makers’ control. This means that it is the more malleable factors leading to the underlying levels of poverty segregation that should be addressed by any state wanting a fair and mixed national school system. In England, these controllable factors include the use of proximity to decide contested places at schools, and school diversity as represented by the growth of Academies and Free Schools, and the continued existence of faith-based and selective schools.
Improved Global Soft Decision Incorporating Second-Order Conditional MAP in Speech Enhancement

In this paper, we propose a novel method based on the second-order conditional maximum a posteriori (CMAP) to improve the performance of the global soft decision in speech enhancement. The conventional global soft decision scheme is found through investigation to have a disadvantage in that the global speech absence probability (GSAP) in that scheme is adjusted by a fixed parameter, which could be a restrictive assumption in the consecutive occurrences of speech frames. To address this problem, we devise a method to incorporate the second-order CMAP in determining the GSAP, which is clearly different from the previous approach in that not only current observation but also the speech activity decisions of the previous two frames are exploited. Performances of the proposed method are evaluated by a number of tests in various environments and show better results than previous work.
Identifying Intrusions in Computer Networks based on Principal Component Analysis

Most current anomaly Intrusion Detection Systems (IDSs) detect computer network behavior as normal or abnormal but cannot identify the type of attacks. Moreover, most current intrusion detection methods cannot process large amounts of audit data for real-time operation. In this paper, we propose a novel method for intrusion identification in computer networks based on Principal Component Analysis (PCA). Each network connection is transformed into an input data vector. PCA is employed to reduce the high dimensional data vectors and identification is handled in a low dimensional space with high efficiency and low use of system resources. The normal behavior is profiled based on normal data for anomaly detection and the behavior of each type of attack are built based on attack data for intrusion identification. The distance between a vector and its reconstruction onto those reduced subspaces representing different types of attacks and normal activities is used for identification. The method is tested with network data from MIT Lincoln labs for the 1998 DARPA Intrusion Detection Evaluation Program and testing results show that the method and model is promising in terms of identification accuracy and computational efficiency for real-time intrusion identification.
Peripheral nerve fascicles: Anatomy and clinical relevance

Within a peripheral nerve, the individual nerve fibers are grouped together in fascicles. Whether there is somatotopic organization within these fascicles has long been of interest, the subject of many investigations, and somewhat controversial. Evidence from diverse sources now points to important somatotopic clustering of nerve fibers within most of the length of the nerve. Information is lacking regarding proximal segments, particularly the plexus and spinal nerve root levels. As a result of this somatotopic arrangement, partial focal nerve lesions can produce restricted clinical deficits that defy the classic rules of localization. Examples of such restricted nerve lesions are provided in this review. Recognition of fascicle somatotopy is also important in the surgical approach to disorders of peripheral nerves.

Digital subtraction angiographic imaging of coronary flow reserve.

Recent studies have demonstrated that subjective assessment of the severity of coronary artery stenoses results in poor interobserver concordance and poor correlation with physiologic significance as determined by Doppler measurements of coronary flow reserve. Use of the coronary flow reserve as an integrated measure of the effect of stenosis geometry has been emphasized within the context of quantitative cinemetric analysis. The comparison of two parametric digital subtraction angiographic flow images obtained before and after hyperemic intervention has led to calculation of flow reserve values that correlate well with electromagnetic flowmeter data in dogs. By means of a similar model relating blood flow and image variables, single flow ratio images have been formed. These parametric images provide a two-dimensional display of the ratio of hyperemic flow to baseline flow. Linear temporal interpolation of data from a sequence of cardiac phase-matched subtraction images is used to improve the resolution of the displayed flow ratios. Summation of flow variables measured within the perfusion bed was used to calculate a value for the overall coronary flow reserve and to characterize the significance of isolated lesions in an open-chest canine preparation. A linear regression calculation relating parametric image flow ratio values to electromagnetic flowmeter measurements resulted in a linear fit of y = . 96x - 0.19 with a correlation coefficient of . 90. The direct visual representation of flow ratio distribution provided by the parametric imaging method may aid in the interpretation of multiple complex lesions as well as of single lesions.
Prevalencia de la depresión infantil en Neiva (Colombia)

The aim of this study is to identify the prevalence of depression symptoms and socio-demographical characteristics among boys and girls with depression symptoms with ages ranged 8 to 11 that attend primary school in Neiva (Colombia). A probabilistic sampling by clusters was made with 95% of reliability. The sampling units are school grades from public and private sector. This sample is formed by 63 sampling groups distributed in a random for a total of 1832 subjects. The measurement instrument is the Kovacs’ Children Depression Inventory (CDI) adapted version to the Spanish population by Victoria Del Barrio. The results show a prevalence of 17.09%, the highest number ever reported in Colombia; most of the cases are found in younger children, which is a different fi nding with respect to other studies. A low socio-demographical status is proper of the most of children with depression symptoms.
No Friends to the Left: The British Communist Party's Surveillance of the Far Left, c.1932–1980

Influenced by developments in the Soviet Union in the 1930s, the British Communist Party (CP) began to treat its rivals on the far left, principally the Trotskyists, as class rather than political enemies. Surveillance, including the maintenance of dossiers, began in 1932, but was greatly heightened in the late 1930s, as international tensions, notably the Nazi threat to the Soviet Union, increased. Less attention was paid to the Trotskyists in the later years of the Second World War and in the immediate post-war period, but was intensified during the Party crisis which followed the Twentieth Congress of the Soviet Party. Later, the CP was faced with additional rivals, the Maoists, to monitor. Surveillance came to an end in the 1970s as sectarian attitudes abated and the CP entered its terminal decline.
End-user development: new challenges for service oriented architectures

Service Oriented Architectures (SOA) evolved as an important architectural concept in software engineering. Although the services of an SOA are loosely coupled and reusable, there have been few considerations of SOA in terms of End User Development (EUD). In this paper we will analyze the potential of SOA for the development of adaptable systems and propose challenges, which have to be solved to reach this goal. Our analysis is based on empirical studies and on requirements for EUD systems, taken from earlier research. If SOAs are extended with structures for in-use-modifications (even beyond software technologies), it will be possible to design a new generation of user-adaptable systems.
Effect of prostaglandin E2 and tumor necrosis factor α on the VEGF‐Receptor system expression in cultured porcine luteal cells

The purpose of the present study was to investigate the effects of prostaglandin (PG) E2 and tumor necrosis factor (TNF) α on expression of vascular endothelial growth factor (VEGF) and its receptors, fms‐like tyrosine kinase (Flt‐1) and fetal liver kinase‐1/kinase insert domain‐containing receptor (Flk‐1/KDR), in cultured porcine luteal cells. Real‐time PCR was used for quantification of VEGF and its receptors mRNA, whereas VEGF release by luteal cells was determined by radioimmunoassay (RIA). Only the highest dose of PGE2 (1 µM) after 6 hr of incubation stimulated VEGF release by luteal cells collected in the mid‐luteal phase (P < 0.05). Moreover, PGE2 (100 nM, 1 µM) significantly stimulated VEGF secretion by luteal cells in the late phase and during pregnancy on Days 10–12 (P < 0.05). Elevated mRNA expression of both VEGF 120 and VEGF 164 isoforms was found in luteal cells cultured with PGE2. The lack of an effect of PGE2 on VEGF receptors mRNA expression was observed. TNFα was able to significantly stimulate VEGF release from cells obtained in the mid‐ and late luteal phase or during early pregnancy. All tested doses enhanced mRNA levels of VEGF 120 isoform, but not VEGF 164. Additionally, TNFα was able to decrease Flk‐1/KDR mRNA expression, whereas Flt‐1 mRNA levels were not affected. These results indicated that PGE2 and TNFα influenced VEGF ligand‐receptor system expression in porcine luteal cells and may therefore play an important role in regulation of luteal functions during the estrous cycle and pregnancy in pigs.

Tourism Entrepreneurship – Review and Future Directions

Abstract Entrepreneurship has received increased attention within tourism research, reflecting the important role of entrepreneurs and new firm start-ups within the tourism industry for innovation and value creation. Although it is expanding, the literature on tourism entrepreneurship remains dispersed. It embraces a number of different issues, perspectives and approaches, and thus far, little congruent knowledge has been developed. This paper addresses this gap by reviewing and analysing the current literature on tourism entrepreneurship. We examine the development in published articles from 2000 to 2012 and discuss how the literature on tourism entrepreneurship relates to the mainstream entrepreneurship literature in terms of research questions, theoretical perspectives and applied methods. We differentiate between a convergent approach in which studies build on mainstream entrepreneurship theorising to examine the context of tourism and a divergent approach in which studies consider tourism entrepreneurship to be different from other types of entrepreneurship, thus needing specific theoretical insights. Trends reflecting convergent and divergent approaches are identified. Furthermore, we discuss potential contributions from tourism entrepreneurship research to the mainstream entrepreneurship literature and vice versa. Based on the findings from the review and analysis, we suggest future directions for research on tourism entrepreneurship.
Ultrasonic backscatter from rat blood in aggregating media under in vitro rotational flow

Ultrasonic backscatter from flowing and static rat red blood cells (RBCs) in autologous plasma and in 360 kDa polyvinylpyrrolidone (PVP 360) solution was measured as a function of hematocrit. The flow speed was varied by a stirring magnet in a cylindrical chamber. The radio-frequency (RF) signals backscattered by RBC samples were measured over 5 min in a pulse-echo setup with a 5 MHz focused transducer. Although the intact rat blood has poor RBC aggregability, RBC aggregation of rat blood was enhanced by replacing its plasma with a higher molecular weight polymer solution. The experimental results showed that the nonlinear relationship between hematocrit and ultrasonic backscatter from rat RBCs in plasma and aggregating media is affected by flow speed, which may provide a unified insight into hematocrit dependence of RBC aggregation under flowing and static conditions.
Trafficking Risks for Refugees

This paper will provide an overview of both the constant and emerging facets of the refugee condition contributing to trafficking risk, and will offer policy and practice recommendations for risk reduction. The perspective offered is that of a national non-profit organization Lutheran Immigration and Refugee Service which resettles refugees from around the world in forty-five communities across the United States, serves asylum-seekers and other at-risk migrants in detention, and works with smuggled and trafficked migrant children. LIRS is a national faithbased nonprofit organization, founded in 1939, which works to engage communities in service to and advocacy for migrants and refugees. Our primary expertise in the area of refugees and trafficking comes from two decades of experience working with migrant children, the insights we have gained in serving “women at risk”, and our knowledge of the vulnerabilities within refugee populations in the post-resettlement period.
Expressing Constitutively Active Rheb in Adult Neurons after a Complete Spinal Cord Injury Enhances Axonal Regeneration beyond a Chondroitinase-Treated Glial Scar

After a spinal cord injury (SCI), CNS axons fail to regenerate, resulting in permanent deficits. This is due to: (1) the presence of inhibitory molecules, e.g., chondroitin sulfate proteoglycans (CSPG), in the glial scar at the lesion; and (2) the diminished growth capacity of adult neurons. We sought to determine whether expressing a constitutively active form of the GTPase Rheb (caRheb) in adult neurons after a complete SCI in rats improves intrinsic growth potential to result in axon regeneration out of a growth-supportive peripheral nerve grafted (PNG) into the SCI cavity. We also hypothesized that treating the glial scar with chondroitinase ABC (ChABC), which digests CSPG, would further allow caRheb-transduced neurons to extend axons across the distal graft interface. We found that targeting this pathway at a clinically relevant post-SCI time point improves both sprouting and regeneration of axons. CaRheb increased the number of axons, but not the number of neurons, that projected into the PNG, indicative of augmented sprouting. We also saw that caRheb enhanced sprouting far rostral to the injury. CaRheb not only increased growth rostral and into the graft, it also resulted in significantly more regrowth of axons across a ChABC-treated scar into caudal spinal cord. CaRheb+ neurons had higher levels of growth-associated-43, suggestive of a newly identified mechanism for mTOR-mediated enhancement of regeneration. Thus, we demonstrate for the first time that simultaneously addressing intrinsic and scar-associated, extrinsic impediments to regeneration results in significant regrowth beyond an extremely challenging, complete SCI site. SIGNIFICANCE STATEMENT After spinal cord injury (SCI), CNS axons fail to regenerate, resulting in permanent deficits. This is due to the diminished growth capacity of adult neurons and the presence of inhibitory molecules in the scar at the lesion. We sought to simultaneously counter both of these obstacles to achieve more robust regeneration after complete SCI. We transduced neurons postinjury to express a constitutively active Rheb to enhance their intrinsic growth potential, transplanted a growth supporting peripheral nerve graft into the lesion cavity, and enzymatically modulated the inhibitory glial scar distal to the graft. We demonstrate, for the first time, that simultaneously addressing neuron-related, intrinsic deficits in axon regrowth and extrinsic, scar-associated impediments to regeneration results in significant regeneration after SCI.
Circinus X-1: survivor of a highly asymmetric supernova

We have analyzed the kinematical parameters of Cir X-1 to constrain the nature of its companion star, the eccentricity of the binary and the pre-supernova parameter space. We argue that the companion is most likely to be a low-mass (< 2.0 M_sun) unevolved star and that the eccentricity of the orbit is 0.94 +/- 0.04. We have evaluated the dynamical effects of the supernova explosion and we find it must have been asymmetric. On average, we find that a kick of 740 km/s is needed to account for the recently measured radial velocity of +430 km/s (Johnston, Fender & Wu) for this extreme system. The corresponding minimum kick velocity is 500 km/s. This is the largest kick needed to explain the motion of any observed binary system. If Cir X-1 is associated with the supernova remnant G321.9-0.3 then we find a limiting minimum age of this remnant of 60000 yr. Furthermore, we predict that the companion star has lost 10% of its mass as a result of stripping and ablation from the impact of the supernova shell shortly after the explosion.
Self and Social Judgments of Ability: Beyond Distributional Information

ABSTRACT In a given domain, low-skill individuals typically evaluate the ability level of other people more favorably than high-skill individuals. The current study tests whether this tendency continues to occur even when people have unambiguous distributional information available through which to judge others. Students received distributional information detailing their percentile rank in a statistics course and the percentile rank of another student in the course. Then, students were asked to evaluate their own and the other students' statistics ability. Students evaluated the other person's ability more favorably when their own rank in the course was low rather than high. Therefore, people may use themselves as a standard of comparison when they judge others even when more diagnostic sources of information are available.
Reservoir optimization in recurrent neural networks using kronecker kernels

In this paper, using the mathematical properties of self-kronecker-production of small size random matrices, a simple but effective method is presented to optimize the reservoir of an echo state network given a certain task. The experimental results investigating the NARMA system show that few steps of the proposed optimization process can lead to a near optimum solution.
Psychometric properties of the volunteer functions inventory with Chinese students

The authors report an evaluation of the psychometric properties of a Chinese version of the Volunteer Functions Inventory on a sample of university student volunteers. Reliabilities were high for four out of the six scales of the Inventory (Values, Career, Social, and Understanding) in terms of internal consistency. Items in these four scales also yielded a clean structure in an exploratory factor analysis. Making new friends was found to be a motive, which was separate from sustaining friendships and separate from other motives captured by the Inventory. Confirmatory factor analysis supported the superiority of a 6-factor model over other measurement models such as unitary, bipartite, and second-order factor models. Implications for the measurement of motives in volunteerism in general and refinement of the Inventory in particular, are discussed. © 2009 Wiley Periodicals, Inc.
