A Comparative study of Friendship Therapy Groups for Thais with Colorectal Cancer and Colostomies

Patientswith cancer need strong social support to help them deal with life-threateningaspects of their illness and in Thailand The Friendship Therapy Group wasinitiated for this purpose in 2005. This comparative descriptive study exploredand compared the perceived stress, stress appraisal, coping, and quality oflife of patients with colorectal cancer and colostomies who participated inthis Group compared to those who did not. Of 87 patients with colostomies, 30 participated and 57 did not. Datawere collected in three hospitals via six instruments: the Personal InformationForm, the Perceived Stress Scale, the Stress Appraisal Index, theFunctional Assessment of Cancer Therapy-Colorectal Cancer, the Waysof Coping Questionnaire, and the SocialActivity Participation and Evaluation Tool; and analyzed through descriptivestatistics, and MANOVA. Results showed that there were no significantdifferences in variables between groups. The mutually supportive activity wasthe group activity that they mostly preferred and thought it was helpful. Other activities may have been less relatedto mutual support; therefore the purpose of those activities of truly mutualsupport should not be lost. Understanding the stress, coping, and QOL, of thesegroups will be useful to help nurses guide the development of futureinterventions for these patients.
Corporate Governance and Value in Brazil (and in Chile)

This paper constructs a corporate governance practices index (CGI) from a set of 24 questions that can be objectively answered from publicly available information. The goal is to measure the overall quality of corporate governance practices of the largest possible number of firms. CGI levels have improved over time in Brazil, and an examination of CGI components demonstrates that Brazilian firms perform much better in disclosure than in other aspects of corporate governance. This paper finds very high concentration levels of voting rights leveraged by the widespread use of indirect control structures and non-voting shares. The paper does not find evidence for either entrenchment or incentives in Brazil using ownership percentages, but evidence is found that the separation of control from cash flow rights destroys value. The CGI maintains a positive, significant, and robust relationship with corporate value. A worst-to-best improvement in the CGI in 2002 would lead to a 0. 38 increase in Tobin’s q. This represents a 95 percent increase in the stock value of a company with the average leverage and Tobin’s q ratios. Considering our lowest CGI coefficient, a one-point increase in the CGI score would lead to a 6. 8 percent increase in the stock price of the average firm in 2002. No significant relationship is found between governance and the dividend payout. The results are placed in context by offering a comparative analysis with Chile.

Study of Somatic Embryogenesis Potential of Male Florets and Pistillate Flowers of Persian Walnut (Juglansregia L.)

Male florets and pistillate flowers of cvs.Chandler and Hartley of Persian walnut were cultured on modified Murashige and Skoog medium (MS) supplemented with 0.05 mg l -1 biotin, 0.5 mg l -1 folic acid, 100 mg l -1 glutamine and different concentrations of Naphthalene acetic acid (NAA) and Kinetin (KIN) and for pistillate flowers culture, these concentrations were 0.25, 0.5, 1 and 2 mg l -1 ). After four weeks, the percentage of callogenesis of male florets in cv. Chandler was more than cv. Hartley. In the sixth and tenth weeks, the rate of callogenesis of male florets was depended on cultivars, the ratio of NAA: KIN and interaction between them; so in the sixth week, the highest rate of callogenesis was obtained in the higher ratio of NAA: KIN. In the tenth week, the effect of cultivars was not significant and the highest rate of callogenesis of male florets was obtained in treatments 4 (2.5 mg l -1 NAA with 1.25 mg l -1 KIN), 5 (1.25 mg l -1 NAA with 1.25 mg l -1 KIN), 7 (2.5 mg l -1 NAA with 0.5 mg l -1 KIN) and 8 (1.25 mg l -1 NAA with 0.5 mg l -1 KIN) of cv. Chandler. By culturing pistillate flowers on modified MS medium, nodular compact calli formed on the upper and lower part of flowers. During the next weeks, callogenesis occurred in sepals and leaflets of pistillate flowers and then stigmas and styles swelled and formed nodular calli. Similar to male florets, the rate of callogenesis in pistillate flowers depended on cultivars, the ratio of NAA: KIN and interaction between them. In the sixth and tenth weeks, the highest rate of callogenesis of cv. Chandler pistillate flowers was obtained in treatments including high or same concentrations of NAA: KIN. Callogenesis of pistillate flowers of cv. Hartley was achieved from different ratios of NAA: KIN. The lowest rate of callogenesis in the sixth and tenth weeks was obtained in the low concentrations of NAA and KIN. With increase of callogenesis in treatments 3 (0.5 mg l -1 NAA with 2 mg l -1 KIN), 6 (1 mg l -1 NAA with 1 mg l -1 KIN), 10 (1 mg l -1 NAA with 0.5 mg l -1 KIN), 11 (0.5 mg l -1 NAA with 0.5 mg l -1 KIN), 12 (0.25 mg l -1 NAA with 0.5 mg l -1 KIN), 14 (1 mg l -1 NAA with 0.25 mg l -1 KIN), 15 (0.5 mg l -1 NAA with 0.25 mg l -1 KIN) and 16 (0.25 mg l -1 NAA with 0.25 mg l -1 KIN) of cv. Chandler and treatments 9 (2 mg l -1 NAA with 0.5 mg l -1 KIN) and 11 (0.5 mg l -1 NAA with 0.5 mg l -1 KIN) of cv. Hartley, the tissues of pistillate flowers turned into
Contrasting the effects of adaptation and synaptic filtering on the timescales of dynamics in recurrent networks

Neural activity in awake behaving animals exhibits a vast range of timescales that can be several fold larger than the membrane time constant of individual neurons. Two types of mechanisms have been proposed to explain this conundrum. One possibility is that large timescales are generated by a network mechanism based on positive feedback, but this hypothesis requires fine-tuning of the strength or structure of the synaptic connections. A second possibility is that large timescales in the neural dynamics are inherited from large timescales of underlying biophysical processes, two prominent candidates being intrinsic adaptive ionic currents and synaptic transmission. How the timescales of adaptation or synaptic transmission influence the timescale of the network dynamics has however not been fully explored. To address this question, here we analyze large networks of randomly connected excitatory and inhibitory units with additional degrees of freedom that correspond to adaptation or synaptic filtering. We determine the fixed points of the systems, their stability to perturbations and the corresponding dynamical timescales. Furthermore, we apply dynamical mean field theory to study the temporal statistics of the activity in the fluctuating regime, and examine how the adaptation and synaptic timescales transfer from individual units to the whole population. Our overarching finding is that synaptic filtering and adaptation in single neurons have very different effects at the network level. Unexpectedly, the macroscopic network dynamics do not inherit the large timescale present in adaptive currents. In contrast, the timescales of network activity increase proportionally to the time constant of the synaptic filter. Altogether, our study demonstrates that the timescales of different biophysical processes have different effects on the network level, so that the slow processes within individual neurons do not necessarily induce slow activity in large recurrent neural networks.
The Effect of Role Predictability and Word Predictability on Sentence Comprehension

The purpose of this study was to investigate whether the degree of difficulty in the integration of a word into a sentence could be determined by not only how likely the word would be for a given context but also how likely the thematic role associated with the word would be to occur. For our aim, we used dative sentences in Korean in which three arguments (i.e., agent, recipient, and patient/theme) appeared prior to a sentence-final verb. We manipulated 1) the degree of role predictability corresponding to the third argument by scrambling the internal arguments that occurred after an agent and 2) the predictability of words corresponding to the third arguments that was either highly likely or unlikely for a given context. A self-paced moving window reading with a secondary judgment task was conducted. A linear mixed-effect regressions on the reading times of the words corresponding to the third arguments was run while controlling for the effects of lexical frequencies and lengths on the processing of target words. The results from the model revealed that the words were read faster when they were highly likely for given contexts than when they were unlikely, and importantly, that the words were read faster when the roles associated with the words were strongly expected than when they were weakly expected. Our results showed that both role predictability and word predictability had independent effects on the processing of a word in a sentence. We claim that a processing model should be loaded with at least two components that take into account role predictability as well as word predictability.
UCLA Adaptive Optics for Extremely Large Telescopes 4 – Conference

The adaptive module of the 4-m SOAR telescope (SAM) corrects ground-layer turbulence using a UV laser guide star. It has been commissioned in 2013 and in regular science operation since 2014A. SAM works with the CCD imager covering a 3 field or with the speckle camera. The instrument operates routinely and stably, delivering in the I band the image quality equal to the free-atmosphere seeing. Preparation of the observing runs and the operational sequence are covered briefly. Observing programs executed so far are presented, ranging from star clusters and binary stars to deep-space objects and gravitational lenses. Emission-line objects were observed with narrow-band filters and Fabry-Perot etalon. Future science use of SAM and its synergy with wide-field optical sky surveys are outlined. New instruments for SAM and its potential upgrades are considered.
Implicit LOD using points ordering for processing and visualisation in Point Cloud Servers

Lidar datasets now commonly reach Billions of points and are very dense. Using these point cloud becomes challenging, as the high number of points is intractable for most applications and for visualisation.In this work we propose a new paradigm to easily get a portable geometric Level Of Details (LOD) inside a Point Cloud Server.The main idea is to not store the LOD information in an external additional file, but instead to store it implicitly by exploiting the order of the points.The point cloud is divided into groups (patches). These patches are ordered so that their order gradually provides more and more details on the patch. We demonstrate the interest of our method with several classical uses of LOD, such as visualisation of massive point cloud, algorithm acceleration, fast density peak detection and correction.
Announcement Effects on Exchange Rate Movements: Continuity as a Selection Criterion among the REE

The aim of this paper is to analyse the announcement effects on exchange rate movements using the basic asset pricing model, where currency trade is partly determined by technical trading in the form of moving averages since it is the most commonly used technique according to questionnaire surveys.Specifically, the announcement and implementation of temporary as well as permanent monetary policy are analysed, where the exchange rate model developed is summarised in a linear difference equation in current exogenous fundamentals, a large number of lags of the endogenous exchange rate and time-t dating of exchange rate expectations. However, since there are a large number of rational expectations equilibria, continuity is proposed as a selection criterion among the equilibria, meaning that the parameter for the time-t - 1 exchange rate should have the limit 0 when there is no technical trading to have an economically meaningful equilibrium.It turns out that there is a unique rational expectations equilibrium that satisfy the continuity criterion, and focusing on this equilibrium, it is shown that the exchange rate is much more sensitive to changes in money supply than when technical trading is absent in currency trade.This result is important since it sheds light on the so-called exchange rate disconnect puzzle in international finance.Key words: asset pricing, exchange rate disconnect puzzle, heterogeneous agents, least squares learnability, monetary policy and technical trading.

Analysis of the timbre of Slovak folk reed aerophones using source‐filter model

Bagpipes are the only group of traditional folk reed instruments that have survived in Slovak folk culture until now. Unlike Scottish highland pipe, gaita, cornemuse etc., all the types of Slovak bagpipes use single reeds in both chanters and drones. Moreover the horns of the drones are partly closed with a plate having only a small opening for air output and sound radiation. This forms a Helmholz‐like resonator ‐ acoustic filter having a strong influence on the acoustic and aesthetic properties of the sound. The ideal of the sound timbre of these pipes is "less open" (compare to open and closed vowels in speech) and, in spite of its relatively high loudness, "less agressive" in comparison to pipes with open horns. This paper presents our approach to study the ideal of sound timbre of the Slovak bagpipe using a source‐filter all‐pole model. To identify resonance frequencies/formants, we applied inverse filtering technique using discrete linear prediction. Some properties of the source (reed) were studied using parameters like amplitude qutient and open quotient. The possible relations between timbre of speech sounds (vowels) and the timbre of the sound of musical instruments are discussed.
Organic super-electron-donors: initiators in transition metal-free haloarene–arene coupling

Recent papers report transition metal-free couplings of haloarenes to arenes to form biaryls, triggered by alkali metal tert-butoxides in the presence of various additives. These reactions proceed through radical intermediates, but understanding the origin of the radicals has been problematic. Electron transfer from a complex formed from potassium tert-butoxide with additives, such as phenanthroline, has been suggested to initiate the radical process. However, our computational results encouraged us to search for alternatives. We report that heterocycle-derived organic electron donors achieve the coupling reactions and these donors can form in situ in the above cases. We show that an electron transfer route can operate either with phenanthrolines as additives or using pyridine as solvent, and we propose new heterocyclic structures for the respective electron donors involved in these cases. In the absence of additives, the coupling reactions are still successful, although more sluggish, and in those cases benzynes are proposed to play crucial roles in the initiation process.
Beautiful Plantations: can intensive silviculture help Canada to fulfill ecological and timber production objectives?

There is growing international agreement that intensive silviculture will play a major role in meeting future demand for wood and wood fibre worldwide. In Canada, however, extensive forest management continues to be the dominant paradigm. Driven by low growth rates in primary forests and the consequent long rotations, current policies support only basic management, with little or no silvicultural intervention between stand initiation and final harvests. By contrast, native conifers and hybrid poplars (Populus spp.) grown in plantations have been shown to achieve increments of 6 to 29 m 3 ha -1 yr -1 in Canada. In this paper, we argue that increased production, economic, and environmental benefits can be realized in Canada by intensifying silvicultural practices over designated parts of the landbase. Indeed, the shift to intensive management may be essential to sustain Canada’s competitiveness in the international forest products sector. In reviewing past work, we demonstrate that intensive silviculture may yield outputs that are competitive with many other regions, even those in the tropics. Achieving wide support for intensive silviculture will require integration of a broader range of silvicultural, environmental, and social objectives into management planning than has traditionally been the case. Such a broad-based strategy, especially where it has gained the support of communities, may be the most balanced and effective means of resolving many of the key forest management issues that face Canada in the 21 st Century.
PREVALENCE OF THEILERIOSIS IN BUFFALOES AND DETECTION THROUGH BLOOD SMEAR EXAMINATION AND POLYMERASE CHAIN REACTION TEST IN DISTRICT LAHORE

Blood samples (336) were collected record prevalence of Theileriosis in buffaloes from twenty one villages of District Lahore. High fever, lacrimation, swelling of sub mandibular and sub scapular lymph nodes, weakness, increased respiration & pulse, corneal opacity, anorexia, loss of condition, pale conjunctiva, anemia, in-coordination and rough hair coat were observed in buffaloes suffering from theileriosis during summer months. Packed cell volume, haemoglobin concentration, total erythrocytic count, and blood smear examination showed presence of macrocytic hypochromic anemia in buffaloes infected with the disease. Based on microscopic examination 39.9 (134/336) prevalence was recorded as compared to 53.3% (179/336) with polymerase chain reaction (PCR) test.
Control strategy based on equivalent fundamental and odd harmonic resonators for single-phase DVRs

In this paper, a digital control strategy based on equivalent fundamental and odd harmonic resonators is proposed for single-phase DVRs. By using a delay block, which can be equivalent to a bank of resonators, it rejects the fundamental and odd harmonic disturbances effectively. The structure of the single closed-loop control system consists of a delay block, a proportional gain and a set of zero phase notch filters. The principle of the controller design is discussed in detail to ensure the stability of the system. Both the supply voltage and the load current feedforwards are used to improve the response speed and the ability to eliminate disturbances. The proposed controller is simple in terms of its structure and implementation. It has good performances in harmonic compensation and dynamic response. Experimental results from a 2kW DVR prototype confirm the validity of the design procedure and the effectiveness of the control strategy.
Biparental crosses confirmed by SSR with Mendelian inheritance in sugarcane breeding

En los programas de mejoramiento de caña de azúcar (Saccharum spp.), los progenitores empleados en los cruzamientos se clasifican como masculinos o femeninos según las cantidades relativas de polen viable producido. La alta producción de polen, favorecida por las condiciones ambientales, reduce la disponibilidad de inflorescencias femeninas y restringe la posibilidad de combinación en los cruzamientos. Sin embargo, los progenitores masculinos pueden ser empleados como progenitores femeninos cuando se aplica un tratamiento de emasculación efectivo. Una aproximación ideal para determinar la hibridez consiste en la utilización de marcadores moleculares, especialmente los microsatélites (SSR). Para determinar la efectividad de un tratamiento de emasculación (inmersión de la panoja en agua a 50oC durante cinco minutos), utilizado en el Programa de Mejoramiento Génetico de Caña de Azúcar (PMGCA) de la Estación Experimental Agroindustrial Obispo Colombres (EEAOC), en Tucumán, R. Argentina, seis combinaciones de cruzamientos (autofecundaciones y recíprocos) entre dos variedades comúnmente usadas como progenitores masculinos, LCP 85-384 and RA 87-3, fueron evaluadas mediante SSRs. Las muestras fueron amplificadas con un par de cebadores que produjeron siete bandas polimórficas y tres monomórficas entre los dos progenitores. Mientras que la segregación mendeliana puede ser difícil de observar en la progenie de un poliploide complejo como la caña de azúcar, el análisis mostró que cada marcador presentó herencia mendeliana (tal como se evaluó por pruebas χ 2 , P≤0,05) para cada combinación de cruzamiento. Los resultados indicaron que el tratamiento de emasculación fue exitoso y que los SSRs hicieron posible la identificación rutinaria de los verdaderos híbridos en la progenie obtenida por mejoramiento en caña de azúcar.
Regression Equation from Dual Energy X Ray Absorptiometry (DEXA) for Estimating Muscle Mass Segment

Metodos antropometricos eran usados para estimar la masa muscular (MM) no especificando valores para segmentos de cuerpo, un hecho critico para individuos que practican actividades fisicas o el diagnostico clinico. En este estudio, 60 atletas recreacionales son evaluados antropometricalmente y por absorciometria de energia dual de Rayos X. La estadistica de regresion lineal posteriormente es usada para establecer el constante el permiso de la obtencion del mm de segmento. Tres ecuaciones fueron obtenidas, un para los miembros superiores: MMUL = (0.533*FAP) - (0.176*RAP) + (0.42*WP) + (0.282*SRL) - 19,985; una segunda ecuacion para la masa muscular de los miembros superiores: MMLL = (0.186*H) - (0.158*LTTL) - (0.024*LTL) + (0451*LP) ­ 24.535; y una tercera para la masa muscular del tronco: TrMM = (0.026*W) + (0.046*H) + (0.154*TTD) + (0.025*NP) ­ (0.025*AP) ­ 5.839. Estas ecuaciones permiten la adquisicion de la informacion detallada sobre la distribucion de MM por una tecnica de acceso facil y rapido, como la antropometria, de un Metodo de Gold Estandar como DEXA.
