Published: September 2019

El tecolote moteado mexicano (TMM; Strix occidentalis lucida), para mantener comunicación con su pareja y tecolotes vecinos, emite vocalizaciones, las cuales varían con el sexo, la estación del año y condiciones climáticas. El TMM, para protegerse de depredadores y condiciones climáticas adversas, selecciona sitios específicos y establece territorios de descanso. Strix occidentalis lucida es una subespecie amenazada debido a la pérdida y fragmentación de sus hábitats. En México, los estudios sobre esta subespecie se refieren en su mayoría a la caracterización de su hábitat y composición de su dieta. Por ello, los objetivos de esta investigación fueron: a) monitorear la emisión de vocalizaciones, b) determinar el tamaño de los territorios de descanso diurno y c) identificar y describir las cuevas seleccionadas por Strix occidentalis lucida para perchar. Para ello, nueve parejas de TMM de tres regiones de la Sierra Madre Occidental se estudiaron de octubre de 2016 a octubre de 2017. El TMM emitió vocalizaciones durante todo el año, su territorio de descanso diurno promedio fue de 0.81 ± 0.77 ha y utilizó cuevas para descansar con mayor frecuencia en invierno (38.9%) y primavera (33.3%). Los resultados de este estudio son de utilidad para entender el comportamiento diurno del TMM y diseñar planes de manejo y conservación del hábitat del tecolote moteado mexicano en México.
Structural and functional characterization of the dry forest in central Argentine Chaco
Authors: Benedictto Mariana N. , Gómez-Valencia Bibiana , Torrella Sebastián A.
Published: September 2019

Here, we studied the composition, structure and functioning of the woody vegetation of a 1000-ha area of the Central Argentine Chaco. First, we identified, through Landsat satellite image processing, three different vegetation classes: two forest types and a savanna. Each class was field surveyed to analyze the composition and structure of the woody plant community. Functioning was assessed through the enhanced vegetation index – a proxy of productivity – obtained from the MODIS sensor. The forest classes showed no differences in composition but some differences in structural attributes, particularly in the density of the dominant tree species in the area, Aspidosperma quebracho-blanco. As expected, the savanna showed less density and basal area of woody plants, with a relative high proportion of tree species seedlings and heliophilous shrubs. The forest class with less density of A. quebracho-blanco presented higher productivity. This could be related to a higher ability of the shrub layer to intercept radiation because shrubs are under an open canopy, as has been noted for early successional stages. Additionally, we found that annual mean productivity for the three classes showed a negative trend in the period 2000-2014. Our results provide valuable information since there are no studies addressing relationships between structural and functional attributes at local level in the Chaco Region.
Estimación de emisiones de GEI y sus trayectorias en grandes incendios forestales en Cataluña, España
Authors: Balde Bountouraby , Vega-García Cristina
Published: September 2019

A escala global, los incendios forestales son una fuente de emisiones significativas de gases y partículas a la atmosfera, emisiones que llegan a afectar grandes extensiones y pueden transportarse a distancias de escala continental. En este trabajo se han estimado las emisiones de los gases de efecto invernadero (GEI) procedentes de grandes incendios forestales ocurridos en los últimos 10 años en Cataluña, España, una región mediterránea muy afectada por la incidencia de fuegos de origen antrópico. Estas estimaciones se basan en la caracterización y cuantificación de la biomasa total de los combustibles forestales preexistentes en las áreas que se queman, la cuantificación de las pérdidas debidas a la combustión según la severidad del incendio y la aplicación de factores de emisión a la biomasa consumida. Los resultados obtenidos indican que los grandes incendios de la última década consumieron porcentajes variables entre 44,4% y 70,3% de la biomasa total disponible en las zonas incendiadas, con emisiones totales de carbono equivalente de entre 15 013 t y 387 335 t por incendio. Para determinar las trayectorias de los penachos de humo y concentraciones alcanzadas se utilizó el modelo Hybrid Single Particle Lagrangian Integrated Trajectory. Los penachos de humo de los incendios estudiados se desplazaron a grandes distancias, generalmente bajo situación anticiclónica, afectando al Mediterráneo y Norte de África.

Published: September 2019

En México existen especies arbóreas, específicamente, el grupo de las coníferas, las cuales permiten analizar y reconstruir las variaciones climáticas del pasado de una o varias regiones geográficas. El objetivo de este estudio fue determinar el potencial de respuesta dendrocronológica de Abies guatemalensis Rehder a la variabilidad climática en Ixtlán de Juárez, Oaxaca. Se desarrollaron cronologías de madera temprana, de madera tardía y de anillo total de 206 años (1810-2015). El análisis de correlación estacional señaló una relación directa entre la cronología RWI residual con la precipitación de invierno-primavera (r = 0.67, p < 0.01) y una relación indirecta con la temperatura máxima de primavera (r = -0.42, p < 0.01) del año actual de crecimiento. Mediante un modelo de regresión lineal se reconstruyó la precipitación acumulada de febrero a abril, de los últimos 136 años (1880-2015), el modelo explicó 44% de la variabilidad de los registros meteorológicos locales del período de calibración (1952-2010). Los períodos más secos ocurrieron en las décadas 1880, 1900, 1940, 1970, 1980, 1990 y 2000. El análisis espectral de la reconstrucción mostró una periodicidad cuasi-cíclica de 2.2 años y 3.8 años, indicando una asociación con el fenómeno ENSO. La sensibilidad de la especie a variaciones climáticas reflejadas en el grosor de los anillos de crecimiento, sugiere que A. guatemalensis tiene potencial para reconstrucciones hidroclimáticas, lo que permitirá extender en el tiempo los registros instrumentales para análisis más amplios de fluctuaciones en el clima y sus tendencias en esta región del país.
Ecuaciones alométricas para estimar biomasa en especies de encino en Guanajuato, México
Authors: Cortés-Sánchez Bossuet G. , Ángeles-Pérez Gregorio , De los Santos-Posadas Héctor M. , Ramírez-Maldonado Hugo
Published: September 2019

Los bosques de encino son importantes en el equilibrio de los ecosistemas donde estos cohabitan, ya que son un grupo de especies con mayor capacidad para fijar y almacenar carbono atmosférico. El objetivo de este trabajo fue desarrollar ecuaciones alométricas para estimar biomasa aérea de seis especies de encino (Quercus rugosa, Q. obtusata, Q. sideroxyla, Q. coccolobifolia, Q. laurina y Q. candicans) con un muestreo destructivo de 165 árboles. Se ajustaron ecuaciones para estimar biomasa por componentes estructurales (fuste, ramas y follaje), y de forma aditiva se estimó la biomasa total, así como una ecuación generalizada para las seis especies, y ecuaciones para estas divididas en dos grupos. Para mejorar la capacidad predictiva de las ecuaciones se ajustaron modelos que incluyen las variables de diámetro normal, altura total y densidad de la madera. El mayor porcentaje de biomasa se concentró en el fuste con 60.6%, mientras que ramas y follaje representaron 36.1% y 3.28%, respectivamente. Las ecuaciones ajustadas explicaron más de 95% de la variabilidad en la biomasa total del árbol y, comparadas con ecuaciones desarrolladas en otros lugares para el mismo género, presentaron un menor sesgo porcentual. Las ecuaciones alométricas generadas pueden ser utilizadas para la región, así como en bosques con características estructurales y de crecimiento similares a las de las comunidades de encino de la sierra de Guanajuato.
Densidad de la madera de 59 especies del orden Sapindales procedentes de bosques naturales brasileños
Authors: Riesco Muñoz Guillermo , Imaña Encinas José , De Paula José Elías
Published: September 2019

Para estimar la biomasa leñosa a partir de las existencias maderables en volumen obtenidas en inventarios forestales, se determinó la densidad básica de la madera en 59 especies arbóreas, para algunas de las cuales escasea la información publicada sobre las características de su madera. Se trata de especies pertenecientes a las familias Anacardiaceae, Burseraceae, Meliaceae, Rutaceae, Sapindaceae y Simaroubaceae, todas ellas incluidas en el orden Sapindales. La densidad básica se obtuvo a partir de muestras procedentes de inventarios forestales realizados en las dos últimas décadas en diversas regiones del Brasil. Se comprobó que la mayor parte de las especies analizadas (68%) presentan maderas livianas o semipesadas (densidad básica entre 0,51 g/cm3 y 0,80 g/cm3) aunque la densidad se mostró muy variable entre especies, desde 0,38 g/cm3 para Simarouba amara hasta 1,25 g/cm3 para Schinopsis lorentzii. Se encontró información bibliográfica sobre densidad básica de la madera para tres cuartas partes de las especies objeto de estudio, resultando que según referencias bibliográficas la madera analizada en este trabajo es 21% más densa que la procedente de las mismas especies en otras regiones. Este trabajo aporta información sobre especies de maderas poco conocidas hasta el momento. Así mismo, las especies arbóreas del orden Sapindales procedentes de Brasil y que fueron analizadas en este trabajo, destacan por la alta densidad básica de su madera, por lo que contribuyen de forma especialmente eficaz a la acumulación de biomasa y a la correspondiente fijación de carbono.

Authors: De la Garza Cárdenas Manuel Humberto , Sánchez Tovar Yesenia , Zerón Félix Mariana
Published: September 2019

El objetivo de este trabajo consiste en profundizar en la presencia de empresas zombis en la Bolsa Mexicana de Valores (BMV) y los factores que inciden en su existencia. Para ello, a través del método CHK se determinó la presencia de empresas zombis en México y, posteriormente, mediante un modelo logit se evalúa el impacto de la rentabilidad y la cuota de mercado en las empresas zombi. Los datos empleados corresponden a 102 empresas inscritas en el mercado de valores de México en el año 2015, lo cual permitió identificar la presencia de 18 empresas con características zombis. Mientras que el análisis empírico confirmó que la cuota de mercado impacta positivamente a las empresas zombis, mientras que la rentabilidad disminuye la probabilidad de incurrir en esta situación. El modelo empleado representa uno de los trabajos pioneros en América Latina sobre este tipo de empresas y da luz sobre el comportamiento que siguen dichas organizaciones mostrando que las características del mercado pueden ser otros predictores importantes de las empresas zombis y representan futuras líneas de investigación relevantes.
Efectos de la comunicación sobre los errores de pronóstico de inflación: evidencia para Colombia para el período 2008-2016
Authors: Anzoátegui Zapata Juan Camilo , Galvis Ciro Juan Camilo
Published: September 2019

El objetivo de este trabajo es examinar los efectos de la comunicación del banco central sobre los errores de pronóstico de inflación para Colombia en el período 2008 – 2016. La metodología empleada consiste en un análisis econométrico compuesto por: i) La estimación de un modelo EGARCH; ii) El uso de Vector Auto regresivos (VAR); y iii) Un análisis de descomposición de varianza. Los resultados del trabajo muestran que los anuncios de política monetaria generan efectos importantes sobre los errores de pronóstico. La principal recomendación de política es que la comunicación es una herramienta que tiene el banco central para reducir los errores de pronóstico. En particular, la comunicación tiene el potencial para lograr una convergencia entre las expectativas de inflación y los objetivos perseguidos por el banco central. La principal limitación está relacionada con la falta de información más desagregada sobre las expectativas de inflación que no permiten analizar su reacción ante diferentes noticias macroeconómicas. La originalidad del trabajo consiste en analizar los errores de pronóstico de inflación con base en la inflación compensada de los títulos de deuda pública.
Rendimiento y volatilidades de los mercados mexicanos bursátil y cambiario
Authors: López-Herrera Francisco , Mota Aragón Martha Beatriz
Published: September 2019

Se analiza la relación entre los rendimientos del mercado bursátil mexicano y los rendimientos (tasa de apreciación) del dólar estadounidense, así como la relación entre sus volatilidades. La evidencia al respecto, incluyendo el ámbito internacional, no es concluyente. El análisis se lleva a cabo mediante la metodología de cópulas, las cuales se seleccionan con base en los criterios de información de Akaike y Schwarz. Las volatilidades fueron estimadas por medio de modelos GARCH asimétricos con parámetros variantes en el tiempo de acuerdo con un proceso de cambios markovianos. La evidencia sugiere que las dinámicas bursátil y cambiaria no siempre están asociadas, pero existe asociación entre los rendimientos accionarios y la apreciación/depreciación del peso frente al dólar y una asociación positiva cuando las volatilidades son altas en ambos mercados. Una consecuencia obvia es que el riesgo cambiario puede ser un riesgo importante para la inversión bursátil, tal como lo asume la teoría financiera convencional, por lo que, aunque no es posible establecer que las dinámicas bursátil y cambiaria estén siempre asociadas, es conveniente establecer políticas de inversión bursátil considerando dicho riesgo.

Published: September 2019

El objetivo del presente trabajo es construir un conjunto de estrategias de trading para capturar la persistencia y memoria de series financieras. Se propone un sistema de trading de baja frecuencia llamado HUELUM, mismo que es probado con el Exchange Traded Fund (EFT) iShares NAFTRAC para precios diarios. La principal contribución de este trabajo es que el sistema de trading HUELUM tiene la capacidad de adaptarse al NAFTRAC, capturando su comportamiento, tendencia y persistencia. El sistema HUELUM es validado a través de un análisis de ventanas móviles, además de que funciona con cualquier activo financiero que registre precios de tipo apertura, máximo, mínimo y cierre (OHLC, por sus siglas en inglés). Cuando nos encontramos en un mercado con poca liquidez y profundidad, HUELUM proporciona señales precisas de compra y venta comparada con una estrategia de buy & hold, asimismo, el sistema de trading propuesto permite la cobertura ante potenciales pérdidas de inversión.
Relating Instructional Design Components to the Effectiveness of Internet-Based Mindfulness Interventions: A Critical Interpretive Synthesis
Authors: Lippmann Marie , Laudel Helena , Heinzle Marlene , Narciss Susanne
Published: September 2019

Background

Internet-based mindfulness interventions are a promising approach to address challenges in the dissemination and implementation of mindfulness interventions, but it is unclear how the instructional design components of such interventions are associated with intervention effectiveness.

Objective

The objective of this study was to identify the instructional design components of the internet-based mindfulness interventions and provide a framework for the classification of those components relative to the intervention effectiveness.

Methods

The critical interpretive synthesis method was applied. In phase 1, a strategic literature review was conducted to generate hypotheses for the relationship between the effectiveness of internet-based mindfulness interventions and the instructional design components of those interventions. In phase 2, the literature review was extended to systematically explore and revise the hypotheses from phase 1.

Results

A total of 18 studies were identified in phase 1; 14 additional studies were identified in phase 2. Of the 32 internet-based mindfulness interventions, 18 were classified as more effective, 11 as less effective, and only 3 as ineffective. The effectiveness of the interventions increased with the level of support provided by the instructional design components. The main difference between effective and ineffective interventions was the presence of just-in-time information in the form of reminders. More effective interventions included more supportive information (scores: 1.91 in phases 1 and 2) than less effective interventions (scores: 1.00 in phase 1 and 1.80 in phase 2), more part-task practice (scores: 1.18 in phase 1 and 1.60 in phase 2) than less effective interventions (scores: 0.33 in phase 1 and 1.40 in phase 2), and provided more just-in-time information (scores: 1.35 in phase 1 and 1.67 in phase 2) than less effective interventions (scores: 0.83 in phase 1 and 1.60 in phase 2). The average duration of more effective, less effective, and ineffective interventions differed for the studies of phase 1, with more effective interventions taking up more time (7.45 weeks) than less effective (4.58 weeks) or ineffective interventions (3 weeks). However, this difference did not extend to the studies of phase 2, with comparable average durations of effective (5.86 weeks), less effective (5.6 weeks), and ineffective (7 weeks) interventions.

Conclusions

Our results suggest that to be effective, internet-based mindfulness interventions must contain 4 instructional design components: formal learning tasks, supportive information, part-task practice, and just-in-time information. The effectiveness of the interventions increases with the level of support provided by each of these instructional design components.

Background

The quality of life (QoL) of patients with osteosarcoma (OS) may be adversely affected by the disease or its treatment. Therefore, it is important to understand the QoL of patients undergoing treatment for OS to improve the QoL. We report on the first prospective international QoL study that was embedded within a large randomized clinical trial from 4 national study groups.

Objective

This paper aimed to describe the QoL study development, methodology, accrual details, and characteristics of the QoL cohort.

Methods

A total of 2260 patients registered in the EURopean AMerican Osteosarcoma Study-1 (EURAMOS-1), of whom 97.92% (2213/2260) were eligible for the optional QoL assessment and could participate in terms of questionnaire availability. Overall, 61.86% (1369/2213) of patients and/or proxies completed the QoL evaluation at the first assessment time point (E1) after the start of preoperative treatment. The QoL measures used (self- and/or proxy reports) depending on the patient’s age and national study group. Participants and nonparticipants in the ancillary QoL study were compared regarding relevant demographic and disease-related characteristics at registration in the trial.

Results

The participation rate at time point E1 did not differ with regard to age, gender, the occurrence of pathological fracture, or the presence of any metastases at diagnosis. No differences were found regarding the primary tumor site. Only the national study group affiliation had an influence on participation. Participation decreased linearly with trial progress up to 20% at the final time point of QoL assessment.

Conclusions

This study demonstrates the feasibility of international cooperation for the purpose of assessing and understanding the QoL of pediatric and adolescent/young adult patients with cancer. Future outcomes of this QoL substudy will help to adapt interventions to improve QoL.

Published: September 2019

BACKGROUND

Home-based noninvasive ventilation has proven cost-effective. But, adherence to therapy still constitutes a common clinical problem. We hypothesized that a behavioral intervention supported by a mobile health (mHealth) app could enhance patient self-efficacy. It is widely accepted that mHealth-supported services can enhance productive interactions among the stakeholders involved in home-based respiratory therapies.

OBJECTIVE

This study aimed to measure changes in self-efficacy in patients with chronic respiratory failure due to diverse etiologies during a 3-month follow-up period after the intervention. Ancillary objectives were assessment of usability and acceptability of the mobile app as well as its potential contribution to collaborative work among stakeholders.

METHODS

A single-blind, single-center, randomized controlled trial was conducted between February 2019 and June 2019 with 67 adult patients with chronic respiratory failure undergoing home-based noninvasive ventilation. In the intervention group, a psychologist delivered a face-to-face motivational intervention. Follow-up was supported by a mobile app that allowed patients to report the number of hours of daily noninvasive ventilation use and problems with the therapy. Advice was automatically delivered by the mobile app in case of a reported problem. The control group received usual care. The primary outcome was the change in the Self Efficacy in Sleep Apnea questionnaire score. Secondary outcomes included app usability, app acceptability, continuity of care, person-centered care, and ventilatory parameters.

RESULTS

Self-efficacy was not significantly different in the intervention group after the intervention (before: mean 3.4, SD 0.6; after: mean 3.4, SD 0.5, P=.51). No changes were observed in adherence to therapy nor quality of life. Overall, the mHealth tool had a good usability score (mean 78 points) and high acceptance rate (mean score of 7.5/10 on a Likert scale). It was considered user-friendly (mean score of 8.2/10 on a Likert scale) and easy to use without assistance (mean score of 8.5/10 on a Likert scale). Patients also scored the perception of continuity of care and person-centered care as high.

CONCLUSIONS

The integrated care intervention supported by the mobile app did not improve patient self-management. However, the high acceptance of the mobile app might indicate potential for enhanced communication among stakeholders. The study identified key elements required for mHealth tools to provide effective support to collaborative work and personalized care.

Aplicações sucessivas de dejetos suínos podem promover mudanças nos atributos físicos do solo, com ênfase nas vias de formação dos agregados solo. O objetivo deste trabalho foi separar e quantificar os agregados conforme sua via de formação e avaliar a estabilidade desses agregados em área com histórico de aplicações de dejeto líquido de suínos (DLS) e cama sobreposta de suínos (CSS), em sistema plantio direto (SPD). Após 10 anos do uso de dejetos suínos (DS) na sucessão aveia/milho sob SPD, coletaram-se amostras indeformadas de solo nas camadas de 0-5 e 5-10 cm, nos tratamentos sem DS (testemunha), com aplicação de DLS e CSS em doses equivalentes a uma e duas vezes a recomendação de N para o milho e a aveia (DLS1X, DLS2X, CSS1X e CSS2X, respectivamente). Os agregados foram separados conforme os seus padrões morfológicos e vias de formação em biogênicos e fisiogênicos. Em seguida, avaliaram-se o diâmetro médio ponderado (DMP) dos agregados e a distribuição dos agregados nas classes de diâmetro para macroagregados (8,00 > Ø ≥ 2,0mm), mesoagregados (2,0 > Ø ≥ 0,25mm) e microagregados (Ø < 0,25mm), em cada tipo de agregado. A adição de dejetos suínos aumentou a formação de agregados biogênicos. Na área testemunha prevalece a via de formação de agregados fisiogênicos. A aplicação de DLS não alterou o DMP e os macroagregados em relação à testemunha, enquanto a aplicação de CSS aumentou esses parâmetros quando comparada aos tratamentos DLS e Testemunha.

El desconocimiento que tienen las comunidades de las especies que poseen en los huertos mixtos, así como el poco valor que le dan a los usos, llevó a desarrollar la investigación tuvo lugar en la vereda Concepción Alto, una localidad del municipio de Pasto, ubicada a 1,09º8`8” de latitud; -77º30`11” de longitud y a una altura de 2520 msnm. El objeto de la investigación fue recopilar, valorar y sistematizar desde la percepción local el uso y manejo de las especies que componen los huertos mixtos, para ello se seleccionaron a 10 familias como informantes claves, siendo necesario estratificarlas por edad, para determinar en qué estrato se concentra el mayor conocimiento; para ellos se aplicó una entrevista semiestructurada. El análisis del conocimiento se hizo por medio de la metodología AKT 5 (Agroecological Knowledge Toolkit). Entre las variables evaluadas se destacan el uso específico de las especies, manejo y coeficiente de importancia, a las cuales se les realizó un análisis estadístico (prueba de t-student) complementado con un análisis de correlación complementada con una correlación entre las variables edad, escolaridad y número de frases. Los resultados indican que el conocimiento entre los estratos I (µ=94±27), II (µ=127±22) y III (µ=75±13) no mostró diferencias estadísticas significativas (p-value=0,3988 >0,05), es decir, que todos los estratos comparten el mismo conocimiento, obteniendo una correlación negativa entre las variables edad y número de frases (r= -0,31). En cuanto al uso que hacen de los componentes del huerto se destacan los medicinales, alimenticios, forrajeros, leña, madera, sombra y regulación hídrica. El manejo del huerto está condicionado por la experiencia, creencias y nuevos conocimientos adquiridos. En este sentido, los huertos mixtos presentes en la vereda Concepción Alto, son un reservorio de biodiversidad y conocimiento tradicional.

Los principales problemas de la producción de plántulas de tomate en las regiones tropicales residen principalmente por la afectación de los factores climatológicos y el bajo empleo de los biofertilizantes, por lo cual, es importante buscar alternativas eficientes de manejo de los biofertilizantes en estas regiones que aumente la racionalidad y sustentabilidad. El objetivo del trabajo fue evaluar diferentes formas de aplicación de microorganismos en la producción de plántulas de tomate. El diseño fue en Bloques al Azar, en esquema factorial 4x3, el tamaño de las parcelas fue de 2m2 y los factores de estudios fueron la aplicación de microorganismos eficientes en cuatro niveles: sin (0), inoculación de la semilla a 100mL L-1 (S), aplicaciones foliares a 100mL L-1 (F) y la inoculación a la semilla más aplicaciones foliares (S+F) y tres variedades (Amalia, Rilia y Seen-2), con tres repeticiones. Los descriptores evaluados fueron el porcentaje de germinación (%), diámetro del tallo (cm), altura de planta (cm), número de hojas, rendimiento (plántulas m-2) y el ciclo de producción de las plántulas (días). Los resultados mostraron que en las tres variedades de tomate, la combinación de la inoculación a las semillas con las aplicaciones foliares de microorganismos eficientes incrementó el diámetro del tallo, la altura de la planta, el número de hojas y el rendimiento en las variedades Amalia y Rilia en 26,0 % y en la Seen-2 un 25,0% con relación al tratamiento control y el ciclo de producción de plántulas fue reducido en las variedades Amalia y Seen-2 un 24,0% y en la Rilia un 22,0%.

Reasons, rationality, and motivation
Authors: Milevski Voin
Published: September 2019

According to one of the most influential and popular theories in the
contemporary theory of action, an agent S is motivated to perform a certain
act A if and only if she endorses some set of reasons R on the basis of which
it follows that she should perform A, and given that she does not suffer from
some sort of practical irrationality (e.g. depression, weakness of will,
psychopathy, mental or physical exhaustion etc.). At least at first glance,
this theory - which is known as the rationalist motivational internalism -
appears to be uncontroversial and unproblematic. Yet, over the past ten
years, this popular position has faced numerous very serious objections. In
the course of this work, I intend to present some of these objections, in
order to justify the claim that the concept of practical irrationality - i.e.
the concept that plays the central role in this particular version of
internalism - should be left out from the philosophical explanation of
motivation. I will then attempt to defend the conclusion that the rationalist
motivational internalism represents a completely inadequate theory of
motivation.
Self-defence and excuse
Authors: Trajkovski Miroslava
Published: September 2019

The text deals with the difference between two types of defence in
litigation: justifications and excuses. These two defences, according to
John Austin (?A Plea for Excuses?, 1956-57), are mutually exclusive because
justification means accepting responsibility for the act in question and
claiming that it is not bad, while excuse involves accepting that the act in
question is bad, but denies responsibility. I will present arguments against
Austin?s viewpoint that are presented by Douglas Husak in ?On the Supplied
Priority of Justification for Excuse? (2005) and Andrew Botterell in ?A
Primer on the Distinction between Justification and Excuse? (2009). I will
show that their reasons are inconsistent with the basic standards of
self-defence, which is a paradigmatic case of justification.
The evolutionary model of empathy: Do non-human primates have building blocks of morality?
Authors: Zivanovic Igor
Published: September 2019

Empathy represents the capacity of an individual to directly experience
others? emotional states. Psychologist Stephanie Preston and primatologist
Frans de Waal proposed the evolutionary model of empathy based on the
common-coding theory of perception and action. In this paper, I will examine
the emotional and cognitive aspects of their account of empathy, as well as
its significance for the evolution of psychological altruism and morality.
In the same context, I will also examine the experimental evidence on
empathy based altruistic helping in children and non-human primates whose
behavioral patterns indicate the presence of what de Wall calls the building
blocks of morality. Finally, I will try to answer how the building blocks of
morality relate to morality as a full-blown phenomenon.

Published: September 2019

In this paper I will investigate different models of democracy for the
European Union. I focus on the solutions that stress the importance of trust
and mechanisms of democratic control at the supranational level. In that
regard, I will consider different models of democracy for the European
Union, both those that are state-centered and cosmopolitan. I defend the
cosmopolitan model which includes the conception of deliberative democracy.

The learning device functions as a guide in carrying out the learning process in the classroom. Javanese language teachers in SMP in Karanganyar Regency, in general, have been aware of the importance of renewal in developing and implementing learning tools, in accordance with the applicable curriculum. However, in reality there are still many teachers who do not understand, even still find it difficult to arrange learning tools, so there are still inaccuracies in the learning tools. Training on the preparation of learning tools for Javanese junior high school teachers, especially in Karanganyar Regency based on the applicable curriculum, was felt to be necessary. To support the effectiveness of training activities, it is necessary to innovate in its implementation. One model that can be applied is the tutorial model, with peer tutors and providing feedback. The purpose of implementing the activity by applying the model is that teachers can exchange knowledge, experience, and strengthen cooperation between peers, so that they can provide input and correction if there is inaccuracy. In addition, through giving feedback teachers can find out firsthand the deficiencies in the learning implementation plan that they put together. After applying these methods the ability of Javanese junior high school language teachers in developing learning tools in accordance with the curriculum can be increased. This can be seen from the results of the lesson plans that have been revised by the training participants.
