Robustness Evaluation in Sequential Testing of Composite Hypotheses
Authors: Kharin Alexey
Published: September 2017

The problem of sequential testing of composite hypotheses is considered. Asymptotic expansions are constructed for the conditional error probabilities and expected sample sizes under “contamination” of the probability distribution of observations. To obtain these results a new approach based on approximation of the generalized likelihood ratio statistic by a specially constructed Markov chain is proposed. The approach is illustrated numerically.

Authors: Kukush Alexander , Malenko Andrii
Published: September 2017

A polynomial structural measurement error model is considered. A goodness-of-fit test is constructed based on the quasi-likelihood estimator, which is asymptotically optimal in a large class of estimators. The power of the test is discussed. The test for the linear model with unknown nuisance parameters is studied in more detail. Similar test can be applied to much more general situation, where the estimator is constructed based on a score function.

Robust Independent Component Analysis Based on Two Scatter Matrices
Authors: Nordhausen Klaus , Oja Hannu , Ollila Esa
Published: September 2017

Oja, Sirkiä, and Eriksson (2006) and Ollila, Oja, and Koivunen (2007) showed that, under general assumptions, any two scatter matrices with the so called independent components property can be used to estimate the unmixing matrix for the independent component analysis (ICA). The method is a generalization of Cardoso’s (Cardoso, 1989) FOBI estimate which uses the regular covariance matrix and a scatter matrix based on fourth moments. Different choices of the two scatter matrices are compared in a simulation study. Based on the study, we recommend always the use of two robust scatter matrices. For possible asymmetric independent components, symmetrized versions of the scatter matrix estimates should be used.

A Functional Approach to Configural Frequency Analysis
Authors: Von Eye Alexander , Mair Patrick
Published: September 2017

Standard Configural Frequency Analysis (CFA) is a one-step procedure that determines which cells of a cross-classification contradict a base model. The results are possible types/antitypes depending on whether the observed cell frequencies are significantly lower/higher with respect to the base model. Selecting these cells out does not guarantee that the base model fits. Therefore, the role played by these cells for the base model is unclear, and interpretation of types and antitypes can be problematic. In this paper,  functional CFA is proposed. This model of CFA pursues two goals simultaneously. First, cells are selected out that constitute types and antitypes. Second, the base model is fit to the data. This is done using an iterative procedure that blanks out individual cells one at a time, until the base model fits or until there are no more cells that can be blanked out. In comparison to standard CFA, functional CFA is shown to be more parsimonious, that is, fewer types and antitypes need to be selected out. The methods are illustrated and compared using data examples from the literature.
Model Selection Using Modified Akaike’s Information Criterion: An Application to Maternal Morbidity Data
Authors: Mahbub Latif A.H.M. , Zakir Hossain M. , Ataharul Islam M.
Published: September 2017

The most commonly used model selection criterion, Akaike’s Information Criterion (AIC), cannot be used when the Generalized Estimating Equations (GEE) approach is considered for analyzing multivariate binary response. Recently, a modified version of AIC (mAIC) which is based on quasi-likelihood function is proposed as a model selection criterion. This model selection criterion can be used in the GEE setup. In this study, an application of mAIC is showed in selecting important covariates associated with pregnancy related complications of Bangladeshi women.
Teaching Statistics with Excel A Big Challenge for Students and Lecturers
Authors: Duller Christine
Published: September 2017

This paper has a look on the implementation of basic statistical methods in Excel, in particular in describing data. Often a frequency distribution is the starting point for describing a dataset, but its calculation is not that easy in Excel. Therefore the first section gives some alternatives to the common way. The next part presents some interesting solutions for measures of central tendency and variability provided by Excel. The last important topic is about creating graphs, where Excel has an advantage: creating histograms with unequal interval width is possible.

THE ORIGIN OF WOMEN CREATION IN THE PERSPECTIVE OF SUFI COMMENTARY
Authors: Norhidayat Norhidayat
Published: September 2017

Jika sebagian kalangan feminis muslim menolak riwayat hadis yang menyebutkan tulang rusuk sebagai asal-usul kejadian perempuan pertama kali karena secara tidak langsung menyimbolkan posisi sub-ordinasi bagi perempuan, sebagian kaum sufi, justru memanfaatkan riwayat tersebut dalam penjelasan mereka dan memaknainya secara positif.  Kaum sufi justru menilainya sebagai simbol saling ketergantungan, cinta kasih, dan keberpasangan antara laki-laki dan perempuan. Penulis dalam tulisan ini menyimpulkan bahwa dalam pandangan kaum sufi, perempuan semenjak awal penciptaannya telah ditakdirkan untuk menjadi pasangan bagi laki-laki, sehingga antara keduanya jadi saling melengkapi dan saling ketergantungan. Pandangan ini, tentu saja menepis anggapan tentang subordinasi bagi perempuan.  Pandangan kaum sufi dalam kasus ini sejalan dengan apa yang dikemukakan oleh kaum feminis muslim kontemporer. Namun demikian, berbeda dengan langkah yang diambil sebagian feminis muslim kontemporer, kaum sufi pada umumnya lebih memilih menggunakan ta’wȋl sehingga memberi makna positif ketika memahami hadis-hadis yang menyebutkan asal usul penciptaan perempuan ketimbang mereka harus mencurigai para periwayatnya atau bahkan menganulir hadis-hadis Nabi yang dinilai sahȋh oleh mayoritas ulama.If some Muslim feminists reject the tradition that argues that the Prophet Adam’s ribs as the origin of the first female event for it indirectly symbolizes the subordinate positions for women, some Sufis instead use the narratives in their explanations and positively interpret them. The Sufis judged the notion as a symbol of interdependence, love, and belonging between men and women. The writer in this paper concludes that in the view of the Sufis, women, since the beginning of their creation, have been destined to become a partner for men, so that between the two become complementary and interdependent. This view, of course, dismisses the notion of women’s subordination. The Sufi’s view in this case is in line with what contemporary Muslim feminists have argued. However, in contrast to the steps taken by some contemporary Muslim feminists, Sufis generally prefer to use the ta'wȋl to provide a positive meaning in understanding the traditions which mention the origin of women's creation rather than to suspect their narrators or even annul The Prophet hadiths considered valid (sahȋh) by the majority of scholars.

This study belongs to library study and is also an intellectual biography study. The nature of the study is qualitative which highlights the contributions of thought in the field of Islamic education. The Islamic education approach was applied in order to identify the contribution of thinking to the character of Islamic education, especially on the material aspects. The data were obtained from Ahmad Fahmi Zamzam's work; Empat Puluh Hadis Penawar Hati, Empat Puluh Hadis Akhlak Mulia, Empat Puluh Hadis Kelebihan Ilmu dan Ulama, Empat Puluh Hadis Peristiwa Akhir Zaman, as well as his audio visual lectures or grand recitation related to the research. The Data are grouped according to the theme of Islamic education further in the analysis. Research findings: (1) Heart education is a conscious effort to cultivate the potential of the heart to achieve perfection into a healthy heart (qalbun salîm) to justify our relationship to Allah swt and fellow human beings. (2) The importance of correcting, changing, and maintaining the heart is one of the foundations for the conduct of heart education. (3) The purpose of the heart education is directed to make the students' hearts become good and right. (4) The approach that can be done in the education of the heart is to pay attention and keep the actions of all the potential of the body from acts that can make the heart becomes dirty, by exploiting the potential of the body, the potential of eye, ear, and the potential of lathîfah ar-Rabbâniyyah. (5) The method of the heart education is grouped into two parts; First, the method of the heart education with charitable deeds, such as; prayer, zakat and alms, fasting, reciting al-Qur'an, dhikr, seeking halal rizki, having social awareness, 'amar ma'rûf and nahî munkar, and ittiba'. Second, the method of the heart education with the spiritual charities, such as; repentance, khauf, zuhud, being patient, gratitude, sincerity, mahabbah, and remembering death. (6) The curriculum of the heart education must be integrated with lathîfah ar-Rabbāniyyah i.e al-Qalbu, al-'Aql, ar-Rûh, and an-Nafs. So the educational content given should be directed to meet the spiritual and emotional material needs. (7) Evaluation of the heart education can only be measured by self-protégé children whose measure is the tranquility within the students themselves and generate noble morality.

KONSEP TASWIYAH AL-NAFS DALAM PENGEMBANGAN PRIBADI MANUSIA
Authors: Hamdie Ilham Masykuri
Published: September 2017

The manifestation of human superiority as ‘ahsan al-taqwim’ can be interpreted as the process of developing the level of "inner aspect" of the human called ‘nafs’. In this context the dimensions of ‘nafs’ or soul that exists in the human still leaves a long discussion to be examined further for the purposes of parsing, forecasting and controlling human behaviour, either individually or in groups, both in relation to the field of ‘da'wah’ or education, for the benefit of mobilizing society in nation-building. Therefore, a research on the concept of ‘taswiyah al-nafs’ in the development of the human person becomes important to be conducted. The results has shown that in the process of ‘taswiyat al-nafs’, besides having the freedom of will and choosing between ‘fujur’ or ‘taqwa’ tendencies, man also have the moral responsibility implied as a subtle command and indirectly to take and choose ‘taqwa’. It is because, the essence of ‘taqwa’ is the mastery, control and self-preservation of ‘al-ahwa'. ‘Taqwa’ as an effort of mastery, control and self-preservation is a prerequisite for the process of human development as a civilized being. The effort is essentially a process of an endless human self-development to reach the ideal of ‘insan kamil’—a perfect man reflecting the names and attributes of God—‘al-asma'ul-husna’.

Correlation and path coefficient analysis of yield and its component characters among different accessions of cluster bean [Cyamopsis tetragonoloba (L.) Taub.].
Authors: Lekshmanan Divya K. , Vahab M. Abdul
Published: September 2017

An experiment was carried out to study the correlation between yield components and their direct and indirect effects on the vegetable pod yield in cluster bean using 100 accessions. The correlation study revealed significant positive association of vegetable pod yield and characters viz., pod weight, pod length, pod girth, pods per plant, pod clusters per plant, plant height, shelf life and 100 seed weight. Pod length, pods per plant, plant height and pod clusters per plant were the characters responsible for maximum vegetable pod yield by imparting highest direct effect in path coefficient analysis. The correlation was also positive for these characters. The direct effect of the traits indicated its true relationship with pod yield. Hence, emphasis should be given for these characters, while making selection for high yielding genotypes in cluster bean.

Field experiments were conducted in 2013 and 2014 with eight treatments consisting of combination of four shading periods (shading during vegetative phase (V), reproductive phase (R), whole growing season and a control treatment) and two irrigation regimes (irrigation after depleting 40 and 80 % of available water). Under limited irrigation conditions, the highest PSII quantum yield, the capacity of electrons move beyond QA and electron move from intersystem to PSI acceptor side reduced, with greater decline degree in sunlight treatment. The minimum seed yield was recorded by plants treated with limited irrigation and whole growing season shade. Changes in the state of the photosynthetic electron transport chain and photorespiration rates in response to different shading treatments were primarily related to leaf water loss. In general, the results revealed that shading caused some shade avoidance responses in soybean, which finally reduced seed production.

Quarantine examination of 13,29,901 imported seed samples of various crops during 1999- 2014 revealed presence of exotic bruchids commonly called seed or pulse beetles in 2,819 samples which were detected by X-ray radiography. Thirteen exotic bruchid species viz., Acanthoscelides desmanthi in Desmanths spp. from Colombia, A. obtectus in Phaseolus vulgaris from Argentina, Colombia Mexico, Peru; Bruchidius atrolineatus in Vigna unguiculata from Nigeria; Bruchus affinis in Vicia faba from Afghanistan; B. dentipes in Vicia spp. from Afghanistan, ICARDA (Syria) and Syria; B. ervi in Lens spp. from Afghanistan, Chile, Cyprus, Ethiopia, Germany, Greece, ICARDA (Syria), Iran, Iraq, Italy, Jordan, Lebanon, Mexico, Morocco, Russian Federation, Syria and Turkey; B. nubilis in V. faba from Ukraine; B. rufimanus in V. faba from Afghanistan, Canada, Spain and Syria; B. signaticornis in L. culinaris from ICARDA (Syria); B. tristis in Lathyrus odoratus from ICARDA (Syria); B. tristiculus in V. narborensis from Portugal; Callosobruchus rhodesianus in Vigna unguiculata from Nigeria and C. subinnotatus in V. subterranea from Ghana were intercepted. Many of the pulse beetles were intercepted repeatedly from the same/ different source(s) year after year. All the infested samples were salvaged using suitable disinfestation treatments. None of the intercepted beetles are yet reported from India, and are therefore, of high quarantine significance.

Published: September 2017

Six basic generations viz., P1, P2, F1, F2, B1 and B2 of five selected crosses viz., LGG-460 × WGG-37, TM-96-2 × WGG-37, TM-96-2 × PM-112, MGG-295 × PM-110 and MGG-351 × PM-115 were studied to assess the nature and mode of gene action for yield and its component traits through generation mean analysis. In general, magnitude of dominance effects (h) has greater value than additive effects (d) for majority of the traits in all the crosses. All the traits are under the influence of duplicate epistasis besides additive type of gene effects for which bi-parental mating or inter-se mating may be adopted followed by pedigree method of selection to modify the genetic architecture of greengram for attaining higher yields with desirable properties.

Authors: Shekar G. C. , . Pushpendra
Published: September 2017

Frequency of chlorophyll and viable mutations have been studied following seed treatment of soybean cv.PK 1029 with gamma rays, EMS and their combinations at varying doses. Mutation rate indicated that EMS @ 0.10 % was most potent in inducing the chlorophyll mutations whereas 20 kR was most efficient in inducing the viable mutations. The frequency and spectrum of the induced chlorophyll mutations was in the order of xantha, albino, chlorina and viridis. The frequency and spectrum of the induced viable mutations was in the order of plant type, leaf type, seed type and pod type. Combination of gamma rays and EMS treatment showed high lethality in inducing both chlorophyll and viable mutations.

Authors: Carvalho Carolina , Niedja Martins Maria , Monteiro Carlos
Published: September 2017

En muchos cursos la retroalimentación del profesor es oral, como cuando interactúa con los alumnos, o escrita, como cuando evalúa sus producciones escritas. Pero los recursos tecnológicos y el software educativo están creando nuevos contextos de aprendizaje. En esta comunicación los objetivos son (a) retomar ideas sobre la retroalimentación en situaciones de aprendizaje de contenidos
de Estadística, mediadas por el uso de recursos tecnológicos; (B) reflejar cómo estos recursos generan potencial en la participación con las tareas; (C) revelar la necesidad de que los profesores tengan la oportunidad de trabajar con estos recursos antes de usarlos con los alumnos. Los resultados ilustran que cuando los profesores tienen la oportunidad de explorar contextos donde se recurre a estas herramientas, ellos también desarrollan conocimientos y competencias que les dan confianza para implementarlos en sus clases.

 El objetivo de este trabajo es mostrar un análisis pormenorizado de tareas escolares, que permita comprender potenciales conflictos en el aprendizaje matemático. Se trata de una metodología descriptiva sobre la diversidad de objetos y significados puestos en juego en tareas que involucran gráficos estadísticos, utilizando la noción teórica y metodológica llamada configuración ontosemiótica de prácticas, objetos y procesos. Las tareas que se analizan fueron seleccionadas previamente de libros de texto de Educación Primaria de España. Los resultados que aporta este trabajo reflejan la necesidad de incorporar este tipo de análisis a la formación de profesores de matemáticas, para que puedan comprender la complejidad de los objetos matemáticos que intervienen y emergen en la resolución de problemas y mejorar así, la enseñanza de la estadística.
La dimensión del control en la regla producto en problemas de conteo
Authors: Núñez Vanegas Félix , Sanabria Brenes Giovanni
Published: September 2017

Cuando se realiza la solución de un problema de conteo, por lo general queda la sensación de si se habrá hecho correctamente. Lo anterior se debe entre otros aspectos a que en muchas ocasiones, la solución dada carece del rigor con que se resuelven problemas de otros dominios de la matemática. Cuando estos problemas se resuelven con la rigurosidad matemática, se monitorea el proceso de solución en cada etapa, y se cubren todos los ángulos. Este control, una de las dimensiones que agrega Shoenfeld a las heurísticas que brinda Polya por considerarlas insuficientes para resolver ciertos problemas matemáticos, es sumamente importante en la realización de un correcto conteo y disminuye, o elimina, esa sensación de inseguridad en la solución dada. Empero, en los niveles iniciales, este abordaje no se ajusta, dado que los estudiantes carecen de los conocimientos matemáticos que podrían intervenir en la solución de estos problemas. Una forma alternativa de tener el control del proceso de resolución de ciertos problemas de conteo, es a través de una correcta interpretación y aplicación de la regla del producto. En este trabajo, se exponen una manera de desarrollar la heurística y el control en los estudiantes para resolver ciertos problemas de conteo por medio de la regla del producto. Finalmente, brindaremos un ejemplo de una incorrecta aplicación de esta técnica dada por algunos estudiantes del curso de Métodos Estadísticos de la Carrera de EMAC del Tecnológico de Costa Rica, y la estrategia para advertirlos del error subyacente, mediante una correcta interpretación de la regla del producto.

Germination and seedling establishment in cashew (Anacardium occidentale L.): An interaction between seed size, relative growth rate and seedling biomass
Authors: M.G. Nayak and G.S. Mohana Babli Mog, J.D. Adiga
Published: September 2017

Seeds of cashew were used to determine the effect of seed mass (5.2 to 7.8 g) on germination, seedling emergence and growth
under nursery conditions. Germination percentage and germination time showed significant correlation with seed mass. Large
sized seeds had higher germination percentage (81.6%) and produced more vigorous seedlings. Per cent seedling emergence was
related to seed mass with large sized seeds exhibited faster emergence. Seed mass significantly affected seedling survival and
survival rate was high in seedlings arising from large sized seeds (62.9%). Seedling vigor expressed in terms of shoot and root
length, leaf number, leaf area and total dry matter was significantly affected by seed mass. Seedlings that emerged from large sized
seeds showed better growth and produced heavier seedlings as compared to medium sized seeds. RGR showed significant variation
(0.152 to 0.240 g g-1day-1) among two seed size classes positively correlated with seed mass, leaf area (LA), unit leaf rate per unit
leaf area (ULRM), root to shoot ratio (R/S) and root mass ratio (RMR) and negatively with stem mass ratio (SMR). The study
concluded that the seed mass and RGR have influence on seedling growth and success of seedling establishment in cashew.

Published: September 2017

An investigation was carried out at Deha Tea Estate, Jorhat, Assam during 2015-16 by using different indigenous technical
knowledge (ITK) prevalent among different small tea growers. Fish extract at (0.25, 0.5 and 1%), Polygonum hydropiper at (2.5,
5 and 7.5%) and Azadirachtin (Neemazal-F 5%) were evaluated in field conditions against tea mite. The result showed that fish
extract in combination with cow dung, cow urine and water when sprayed at one per cent concentration, significantly reduced red
spider mite population (96.5%), percentage of leaves infestation (5.2%) and leaf area infested by the mite (11.6%). P. hydropiper
in combination with cow urine and water when sprayed at 7.5 per cent concentration significantly reduced red spider mite
population (87.5%), percentage of infestation (9.1%) and leaf area infested by the mite (12.9%). Among all the ITKs, fish extract
at one per cent caused higher reduction of infestation of red spider mite followed by P. hydropiper extract at 7.5 per cent.
Influence of both the treatments on the management of red spider mite was at par with that of commercial Azadirachtin.

Introduction/Objectives: To assess the efficacy and correlation of MDCT scans in the clinical staging of patients with HNCs prior to therapeutic intervention. Methodology: Thirty-four HNCs were studied according to the 2005 WHO. Clinical AJCC 6th edition & radiological staging. Results: 14 Squamous Cell Carcinoma (SCC 41.2%) mean age 49.4 + 14.7 years, 13 Nasopharyngeal Carcinoma (NPC 38.2%) mean age 37.1 + 20.5 years, 3 Odontogenic Carcinoma (ODC 8.8% made up of 2 cases ameloblastic carcinoma 5.9% and 1 case of ameloblastic carcinosarcoma 2.9%). Others cases were 3 Adenocarcinoma (8.8%) and 1 Sinonasal Carcinoma NC (2.9%). Mean age insignificant according to gender (p = 0.342). Sensitivity, specificity, positive & negative predictive values and accuracy of clinical and radiological nodal involvements were: (47.4%; 80%; 61.8%; 75%; 54.5%) & (78.9%; 93.3%; 85.3%; 93.8%; 77.8%) respectively. Difference between clinical and radiological stages was statistically significant (X2= 260.8; p=0.01). There was a low but positive correlation between the clinical and radiologic stages (Pearson’s correlation r = 0.6). Conclusion: MDCT was significantly more accurate than clinical examination in the TNM of HNCs using AJCC/UICC TNM guidelines. Authors recommend MDCT as first line imaging technique in resource limited settings.

Authors: Lira Ana de Lourdes Sá de , Portela Sabrynna Gonçalves Candeira
Published: September 2017

Aim: Determine the prevalence and incidence of dental caries in children´s deciduous teeth, who were treated with ART technique. Methods: In T1, 62 children were examined for being between 3 and 6 years of age. A questionnaire was applied to the parents or guardians of the children involved in the research, to analyze their knowledge about eating habits and oral hygiene. An intra-oral examination of children from 3 to 6 years old was carried out and dental treatment was performed by the ART technique. Six months after,(T2), the clinical examination was redone to investigate the restorations´stability. Results: In T1, 94 carie cavities were found in 19 children and 86 were recommended for restoration with ART. In T2, 58 restorations were damaged or lost and 15 children had 20 new carie cavities. Conclusion: The prevalence of dental caries in the deciduous dentition was 38.8% and the incidence was 31.9%. In T2, the majority restorations class I and II were damaged or lost. ART technique is an option, despite the high failure in ART, especially for child population with deciduous teeth that has limited access to dental services. However, restorations should be supervised and healthy eating habits implemented.
