Abstract: in morelos, root rot caused by fusarium spp., is one of the main diseases of indoor poinsettia. in order to prevent or control its devastating effect, frequent applications of chemical products are performed, with inherent risks to human health and environment. in quest for alternative biorational options, an essay in which three commercial strains of trichoderma spp., was done, in three different substrates: s1= "organic soil" (70% v/v)+thick tezontle (15% v/v)+thin tezontle (10% v/v)+agrolita (5% v/v); s2= peat moss (80% v/v)+ coconut fiber (20% v/v); s3= "organic soil" (70%)+"tepojal" (30%), in most common commercial varieties, freedom red and prestige red. a factorial design of 4 x 3 x 2 treatment was used and resulting treatments were evaluated in a completely random design with six repetitions. regards root rot incidence, commercial strains of trichoderma spp., did not show differences between them, either with chemical control. root rot was associated with s2, due low aeration capacity, and only it was seen in prestige red. population of trichoderma spp.,(ufc g-1) in the substrate at end of cycle was the same (p< 0.05) between commercial strains and between them and the control (without inoculation), due presence of native strains of trichoderma in organic components of substrates ("organic soil", peat moss and coconut fiber).

Abstract: La variabilidad actual de la calabaza en el sistema milpa en Yucatán ha sido escasamente estudiada. Se caracterizaron 36 poblaciones nativas de calabaza cultivadas en el centro-oriente de Yucatán, de las especies C. moschata (26) y C. argyrosperma (10), durante el 2003 en Yaxcabá, Yucatán, asociadas con una variedad de maíz (Zea mays L.) tipo Xnuc Nal sembrada a 40 000 plantas/ha. Las poblaciones se distribuyeron en un dise o látice simple, con parcela útil de 8 plantas (72 m2 ), a una distancia de 3 m entre plantas; el experimento se condujo con base en las prácticas regionales. Características cualitativas (11) y cuantitativas (14) de planta, fruto y semilla fueron analizadas con componentes principales, correspondencia simple y conglomerados. Ambas especies se separaron con base en sus características morfológicas en forma clara; y dentro de cada especie se formaron subgrupos con características diferenciales. Largo, ancho y peso de 100 semillas, días a floración femenina, grosor de pulpa, y largo y ancho de fruto explicaron mayormente la variación cuantitativa; lóbulo de la hoja, forma longitudinal del fruto e intensidad del moteado de la hoja explicaron mayormente la variación cualitativa. Las poblaciones de C. moschata se caracterizaron por tener semillas peque as de margen delgado, precocidad de intermedia a tardía, diferentes formas y tama os de fruto con mesocarpio grueso y abundante pubescencia en el tallo. En contraste, las poblaciones de C. argyrosperma son más precoces, de semillas más grandes con margen grueso, frutos redondos de tama o peque o a mediano y escasa pubescencia en el tallo.

Abstract: En este escrito pretendo desarrollar la concepción, la metodología, epistemología, la didáctica y la pedagogía que está detras de U jóok'ol t'aan, "La salida del habla", desde y con las voces de algunas madres mayas, obtenidas mediante una investigación etnográfica que forma parte de mi investigación de tesis "La vitalidad del Maaya T'aan. Estudio etnográfico de la comunicación intergeneracional de los mayas de Naranjal Poniente". Por otro lado, también examino la ense anza escolarizada de la lengua maya, específicamente el currículo estatal que se emplea para la ense anza de la lengua maya, y la contrapongo con la adquisición de la misma lengua en las familias para generar caminos hacia una posible interculturalización de la ense anza de las lenguas indígenas.

Dynamical Model with Application to the Analysis of the Sweet Spot on a Baseball Bat  [PDF]
Li Cheng, Zaiqiang Ku
American Journal of Computational Mathematics (AJCM) , 2015, DOI: 10.4236/ajcm.2015.54040
Abstract:

In this paper, we analyze the effect on the ball-bat model of corking the bat, and investigate the relationship between the sweet spot and different materials. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Last but not least, according to different material caused rotary inertia and different recovery coefficient, researches on the different material hitting effect were made.

Zaiqiang Ku, Ting Liao
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.55092
Abstract: Based on the entropy weight method and the gray relational analysis method, we first calculate the weight of each index and the correlation coefficient between the indicators, get the urban intelligent growth index, and then calculate the annual growth rate of the composite index. We find the following results. First, Suzhou to improve its environment, the success rate of 109.67%. Saint Louis to improve its economy, the growth rate of 57.4%. Second, the sensitivity of the data analysis, each of the indicators is increased by 10%, 20%, 30%, other indicators remain unchanged. Recalculate the city’s intelligent growth index, we find that the greater the volatility, the greater the potential. The total population of the city, built green area, the total length of the bus operating a greater potential, built-up area, the smallest regional GDP potential. Finally, we propose an improved model combining remote sensing with GIS to analyze urban expansion and farmland loss from time and space qualitatively and quantitatively.
The Effect of Self-Driving Car on Urban Traffic  [PDF]
Zaiqiang Ku, Ting Liao
American Journal of Computational Mathematics (AJCM) , 2017, DOI: 10.4236/ajcm.2017.72013
Abstract: Based on the idea of infinitesimal analysis, we establish the basic model of relation between speed and flow. Since putting a certain amount of self-driving car will affect the average speed of mixed traffic flow, we choose the proportion of self-driving car to be a variable, denoted by k. Based on the least square method, we find two critical values of k that are 38.63% and 68.26%. When k < 38.63%, the self-driving cars have a negative influence to the traffic. When 38.63% < k < 68.26%, they have a positive influence to the traffic. When k > 68.26%, they have significant improvement to the traffic capacity of the road.
The Shadow Of Past Rivalry: Limits Of Post-1999 Dynamism In Greco-Turkish Relations
Eda Kuku
Caucasian Review of International Affairs , 2008,
Abstract: This essay will enquire whether Turkey and Greece could remove their enduring controversies through confidence building measures, mediation and inter-governmental dialogues which were introduced in the post-1999 détente period. The paper will specifically focus on the recent nature of understanding between the two countries and will endeavour to answer the question of whether there is a divergence in the nature of recent cooperative arrangements from those which were concluded in the former periods of détente and each of which were disrupted by succeeding periods of either armed conflict or cold war. The paper contends that the recent nature of Greek-Turkish relations is not problem-free. Yet, the new cooperative environment facilitated by confidence building measures and growing mutual understanding could help resolve the disputes and dispel reservations in the Aegean and Cyprus which have been very central to national security considerations of both Turkey and Greece. From a security perspective, continuation of previous policies towards one another is counterproductive in the post-1999 period. Improvement of a bilateral dialogue under the EU umbrella is detrimental for the defence considerations of both Turkey and Greece.
Culture and Stigma of Mental Illness: Path Analysis Conducted with Amos in Transcultural Psychiatry in Australia  [PDF]
Tan Kan Ku, Michael Ha
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.36003
Abstract:

Aim: The study was designed to elucidate the relationships between cultural values, contact level, differential nursing practices and stigma towards mental illness among General and Psychiatric Nurses (N = 208) from Anglo and Chinese backgrounds in Australia. The study results aimed at informing education disciplines, health care providers and policy makers to examine strategies that seek to diminish stigma of mental illness and to reflect on cultural sensitive issues associated with mental illness. This paper reports analyses conducted with AMOS-5 within the Chinese sample (n = 84). Method: A cross-sectional survey explored a number of factors such as contact factor, cultural values (Individualism (IND), In group Role Concern (IRC) and In group Interdependence (INT)), “General Stigma” measured by the Social Distancing (STPP) and Negative Stereotyped (DISL) Scales and how these factors might translate into nurses’ endorsement of differential care practices between two vignettes (diabetes versus mental illness), which was termed “Practice Stigma”. “Practice Stigma” was measured by Caring Approach (CARE), Nursing Satisfaction (SATI), Authoritarian Stance (AUTH) and Negativity (NEGA) Scales. Differential practices (DIF_CARE, DIF_SATI, DIF_AUTH and DIF_NEGA) were obtained by subtracting the diabetes case from the mental illness case. Findings: Chinese nurses endorsed more highly collectivist values measured by the variables “In group Interdependence” and “In group Role Concern” when compared with Anglo-Australian nurses, but there was no difference in individualist values measured by “Individualism”. Chinese nurses endorsed more highly general stigma towards mental illness than Anglo nurses when statistically controlled for differences in background demographics and contact factors. Chinese nurses endorsed more care/support and authoritarianism in their clinical approaches than Anglo-Australian nurses, although there was no significant interaction effect between ethnicity and patient type on care and authoritarianism. Chinese nurses endorsed more highly differential negativity than Anglo nurses for the mental illness case than the diabetes case, an effect mediated by differences in general stigma between these two ethnic groups. Within the Chinese sample, higher contact was related to lower differential negativity for the mental illness case than the diabetes case. Several path analyses suggested that Chinese values influenced differential negativity, mediated by general stigma and prior diversified contact with

Negative Stereotyping Attitudes towards Mental Illness: Is It Culturally Related?  [PDF]
Tan Kan Ku, Michael Ha
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.312006
Abstract:

Background: Stigma of mental illness is often related to attitude studies in social science research, cross-cultural psychology and education in social behaviour. Majority of these studies used opinion on mental illness to examine attitudes. Method: A cross-sectional survey was presented to 208 registered nurses in Australia. Principal component analyses (with oblique rotation) were used to identify underlying dimensionality in the correlations of items for negative stereotyping attitudes. Subscale score variations were analysed across nurse type and ethnicity to examine the discriminant validity of the subscales. Results: Principal component analysis (PCA) revealed one dimension accounting for 50.5% of the variations within items for negative stereotyping. Developed as scale, labelled as “Dislike Attributed to Mental Illness (DISL)”, reliability analysis indicated high internal consistency with alpha coefficient of .93. Chinese general nurses scored highest on the DISL scale than the other three groups: Chinese psychiatric nurses, Anglo general and Anglo psychiatric nurses. Conclusion: Psychometric evaluation of the Dislike Attributed to Mental Illness (DISL) indicates that it is a reliable scale for measuring negative stereotyping attitudes towards mental illness. The main statistical significance was due to nurse ethnicity.
