Aso-Ebi (Group Uniform): An Imported Symbolic Culture That Projects Solidarity And Cohesion in Traditional Igbo Cosmology
Authors: Chuks. Madukasi Francis
Published: March 2018

It is a known fact that every culture has the responsibility of describing reality, its origin and models of structural development as well as the hidden knowledge and truth about being. This responsibility is evidently illustrated, addressed or depicted in Igbo paradigm in form of symbols. Devoid of these symbols, signs and images, the traditional life experiences of the Igbo’s will completely be void, abstract and meaningless because some of these symbols represented in tangible visible forms were believed to be real and living. This paper focuses towards understanding Aso-ebi cloth in the Igbo context through the examination of the dynamics of the cloth production, patronage, consumption and social significance of dress projecting high social solidarity and powerful cohesion in traditional Igbo paradigm. The proper underpinning of this social psychology of Aso-ebi cloth on the indigenous people of the Igbo’s will go a long way in the full integration of the Igbo people’s life and their immediate cultural ecology with messages it disseminate. It must be noted also that despite the significance of this integration, it must be informed that such is evidently limited in their transmission of reality. This paper investigates how the Aso-ebi clothe although an imported culture from the Yoruba tradition basically play significant roles in mediating and facilitating religious communication in Igbo Traditional Religion, giving rise to thought, interpretation, and symbolic meanings. In Igbo cosmology and leadership, the Aso-ebi fabrics encapsulate so many things which are very distinctive thereby representing so many things and ideologies.
The Hopeless and the Ict Transformation
Authors: Wilson Cevito
Published: March 2018

Nothing is better than attempting to transform people by boosting their knowledge and improve their living conditions. In Africa and especially in Togo, Elderly people, Artist Painters and Fishermen even though they would like to contribute to their country’s development by their everyday hard-work, are not emerging. Government is not helping and their activities lack efficiency, proper management and appropriate internal communication and with the external world. This is the reason why the ICT in particular People.net, the knowledge charity infrastructure’s potential are proposed as a solution. Communities and various economic sectors could then reinforce their capacity by acquiring the proper knowledge they lack. However, a systemic approach should be considered by the introduction of an efficient and all stakeholders or users accepted ergonomic approach in order to boost the usability of the proposed People.net platform.

Published: March 2018

The objective of the study was to determine the effects of dietary supplementation of fermented extruded corn stover on back fat thickness, reproductive performance and serum hormone in sows during late pregnancy. A total of 48 pregnant sows (24 Landrace and 24 Yorkshire) were randomly assigned into four experimental treatment groups (0%, 10%, 15% and 20% fermented extruded corn stover). Back fat thickness results showed that no significant differences on control group compared to each fermented treatment groups (P>0.05) at 55 and 105 days of gestation, respectively. Reproductive performance results demonstrated that control group had a lower litter size per head than 10% fermented extruded corn stover group (P less than 0.05), respectively. The results showed that leptin hormone was higher in control group than 10%, 15% and 20% treatment groups (P less than 0.05), respectively. Our findings suggested that 10% fermented extruded corn stover increased the litter size per head in pregnant sows.

Published: March 2018

The present study envisaged the effects of different levels of dietary copper supplementation on performance, egg quality parameters, serum and yolk cholesterol and triglyceride levels, and yolk fatty acid profile in laying hens. Total 96 Lohman laying hens (38 weeks old) were randomly divided into four groups (n=24 each). Experimental diets were prepared by adding copper (0, 200, 250 or 300 mg/kg) to basal diet and feeding was lasted 12 weeks. Dietary copper supplementation decreased egg weight and feed intake but did not affect other performance parameters compared to the control diet. Shape index, shell weight, shell thickness, yolk color, yolk index, albumen index, and haugh unit were not influenced by dietary copper supplementation, whereas shell strength increased due to the inclusion of copper in the basal diet. Copper supplementation did not affect the fatty acid profile of the egg yolk. The yolk cholesterol ratio decreased by 7.22% in the presence of 250 mg/kg copper supplementation compared to control diet. Therefore, high levels of dietary copper supplementation in the diet of laying hens can be beneficial for improving shell strength and reducing the cholesterol content of the yolk.

Finding Meaning through Kristen Swanson's Caring Behaviors: A Cornerstone of Healing for Nursing Education
Authors: McKelvey Michele M.
Published: March 2018

Swanson's (1991) middle range theory of caring has traditionally been used to define the care of patients and family members. Swanson's caring theory outlines five caring processes: knowing, being with, doing for, enabling, and maintaining belief (p. 163). Nurse educators can utilize these caring processes to teach nursing students by cultivating meaningful, healing relationships. This article presents an example of a nursing faculty member's application of this theory to her teaching pedagogy. This account serves to guide therapeutic teaching as well as to encourage further scholarly work examining the relationship between Swanson's caring theory and nursing education.
Profiling Pregnant Women at Risk for Domestic Violence in Jamaica: A Pilot Study
Authors: Pitter Cynthia Pearl , Dunn Leith
Published: March 2018

Background:

Domestic violence (DV) is recognized as a priority in maternity care. Data on the prevalence and profile of women experiencing DV during pregnancy are limited in Jamaica. This baseline study has identified the prevalence and provided a profile of pregnant women who are at risk for DV in Kingston, Jamaica.

Method:

A descriptive cross-sectional study was done in 2014. A total of 185 randomly selected pregnant women attending the antenatal clinic completed a self-administered questionnaire. The data were analyzed using SPSS. The study was approved by our local ethical boards and all ethical considerations were adhered to.

Results:

The study identified a prevalence rate of 41% (n= 75/182) which includes all types of DV during pregnancy. Those at risk were 23–29 years old, single (66.6%), employed (44%), had primary education (66.6%), and had unplanned pregnancies (65%). The majority of respondents (98%) were willing to disclose DV, but the clinic does not provide them the opportunity. Only 11% (8/75) reported that they sought professional help.

Conclusion:

This study adds to the body of knowledge on the prevalence of DV and notes that it is high among pregnant women attending the antenatal clinic. The findings can guide the development of a DV screening protocol to identify and treat pregnant women and train health practitioners in Jamaica.
Factors That Affect Sustained Profitability In The Textile Industry Of Tshwane
Authors: Worku Zeleke
Published: March 2018

The textile industry of the City of Tshwane has been overwhelmed by cheap imports from countries such as China, India, Pakistan, Bangladesh, Malaysia, South Korea and Vietnam. Although support is provided to black entrepreneurs in the textile industry of Tshwane by institutions such as the South African National Department of Trade and Industry and the South African Small Enterprise Development Agency, local textile businesses are unable to compete favourably with foreign manufacturers, importers and distributors. The textile industry is a key contributor to the South African GDP and employs about 5% of the South African workforce. One of the key priorities of the City of Tshwane is to transform the textile industry of Tshwane so that it provides sustainable livelihood and career opportunities to black indigenous South Africans. A descriptive, cross-sectional study design was used for collecting data from a stratified random sample of size 250 textile businesses operating in the five geographical zones of Tshwane.  One of the aims of the study was to assess the veracity of the theory proposed by Bansal and DesJardine (2014) in which the authors have argued that changing global circumstances would compel local industries to adapt to global changes at local level as a means of sustained survival. Data analysis was performed by using Structural Equations Modelling (SEM). The results showed that sustained viability in textile businesses was significantly influenced by the degree of entrepreneurial skills, the ability to secure loan needed for operation, and the ability to order merchandise in bulk on credit from suppliers, in a decreasing order of strength. About 32% of business operators had adequate entrepreneurial skills based on the composite index developed by Ács, Szerb and Autio (2011). A repeat of the same study as a 5-yearlong study is recommended in order to estimate theoretically reliable predictors such as hazard ratios for factors that are known to affect viability in the local textile industry.
KEMAMPUAN ARTIKULASI BUNYI BAHASA ARAB PADA ANAK TUNARUNGU (Studi Kasus di SLB Negeri Sampang)
Authors: Adriana Iswah
Published: March 2018

Human being using language through hearing by imitating language sound spoken by another people, but not all human beings born in a perfect condition. Some of them have weaknesses on their hearing which we called hearing impaired/ deaf. It is so because they lack and partly or totally loss their hearing ability because their hearing device does not work properly. The direct effect of hearing impaired/ deaf is the delaying verbal/ aural communication with other people, because we need a clear articulation or pronunciation to communicate with others so that the message can be well-delivered. As it has already known that there are some Arabic sounds that cannot be found in Indonesian, they are ح، خ، ز،ض،ص،ذ، ظ، ط،،ش therefore, as Moslems, the students with hearing impaired should not only be taught to pronounce clear indonesian sounds, but they also need to be trained to read al-Qur’an with the correct makharijul huruf. This study is trying to find out how well the students with hearing impaired pronounce Arabic sounds (both vowel and consonant) and also investigate the factors affecting the pronunciation. The result of the research is, (1) the majority of Arabic sound articulation pronounced by a student with hearing impaired (Lia) is not clear. Some of the consonants are ز،ر، س، ص, ع، ح   ث، ذ، ظ, ق, ك، غ، خ, ف.. While in the vowel sound, it majority happenned in the short vowel sound I (kasrah), long vowel (mad), Harakat sukun and tasydid, while (2) some causing factors of the above problems are distortion, nasality (unclear sound production), and general and plural dyslalia.

Authors: Ko David , Ge Cindy
Published: March 2018

This research explores the phenomenon of firm performance as it relates to the business strategy, characteristics of Chinese Family Business (CFB) in Hong Kong's Electronic Companies, and technology strategy adopted by these firms. The motive to do this research is that there has been very little work on business strategy in export-oriented "developing economies - latecomer economies" as referred by Zahra and Covin (1993). There has also been little work on technology policy/strategy in Hong Kong, although there have been many suggestions that Hong Kong firms "need" to change and up-grade their business strategies. Added to this, Hong Kong firms have interesting characteristics (Chinese Family Business, CFB), which may be related to their business and technology strategies. Performance may be determined by the strategies they adopt. In this research, the key dimensions of "technology strategy/policy" are identified, including Imitation, Original Equipment Manufacturing (OEM) and Original Design Manufacturing (ODM), which are important in Hong Kong, but which have not been explored much in the literature. Hong Kong firms were selected in this topic since as China is found to become the world's manufacturing base and a lot of that industry, especially in Electronics Industry that this is an important topic.

Published: March 2018

The effects of different priming techniques were evaluated to improve the dormancy and germination of wild seeds of “Piquín” chili pepper. Three experiments were designed for pre-sowing treatment of seeds: a) chemical seeds digestion; b) halopriming (with K+ or NH4+ of NO3-, SO42- or Cl-) at different priming times (24, 48 or 72 h) and osmotic potential (-5, -10 or -15 atm) and c) previously selected halopriming (KNO3 and NH4NO3) + Gibberellic acid (GA3, at 100 or 200 ppm) were tested. Digestion treatments did show a negative effect on seed germination. Recommended values of osmotic potential (Ψs), to improve Piquín chili seed germination, must be between -10 and -15 atm (-1.0 and -1.5 MPa) and the priming time must be between 48 and 72 hours. Priming techniques can considerably reduce Capsaicinoids content on seeds, improve dormancy, seed germination performance, and increase the rate and uniformity of seedling establishment. KNO3 and secondly GA3 treatments may improve rapid and uniform germination and seedling emergence. The results provide basic information to develop guidelines for commercial establishment of Piquín pepper crops.

Comparing Methods of Rocky Desertification Monitoring at the Sub-pixel Scale in a Highly Heterogeneous Karst Region
Authors: Qi Xiangkun , Zhang Chunhua , Wang Kelin
Published: March 2018

Karst rocky desertification (KRD) is a process where strong anthropogenic disturbances and exposure of carbonate bedrock occurs in fragile karst ecosystems. The fractional cover of rocky outcrops is a key indicator and mechanistic driver of KRD and can be accurately assessed using remote sensing technology. Nevertheless, rugged karst terrain relief can cause shadow effects on satellite imagery and combine with high heterogeneity of karst landscapes to prevent fractional cover retrievals. In this study, we explored the feasibility of applying multispectral high spatial resolution ALOS imagery for fractional cover extraction of rocky outcrops. We selected the dimidiate pixel model (DPM), which has been applied in previous studies, and spectral mixture analysis (SMA; including simple endmember spectral mixture analysis (SESMA) and multiple endmember spectral mixture analysis (MESMA)) to explore the feasibility of using remote images for KRD monitoring and improve accuracy for estimating fractions. Results from MESMA achieved high overall accuracy (76.4%) in monitoring percentage of rocky outcrop fraction in the study area. SESMA appears to underestimate percentage of rocky outcrop likely because the development of KRD was driven by complex factors (soil erosion, dissolution and anthropogenic disturbances). This results in spectral reflectance of rocky outcrop being variable in different settings. Predicted exposed bedrock coverage using SESMA and MESMA was similar in sun-lit and shaded areas although predictions from SESMA were smaller than reference data. DPM underestimated the fractional cover of rocky outcrops on south-facing slopes and overestimated it in shaded areas. Furthermore, SESMA and MESMA effectively reduced topographic effects. We conclude that it is better to extract percentage of rocky outcrop using MESMA in the karst region of southwestern China. Remote sensing is emerging as a feasible method to extract surface condition information in heterogeneous and rugged landscapes.
Disabled People in Brazil: Risk Question
Authors: de Oliveira Paulo
Published: March 2018

Throughout the world, disabilities people have worse health prospects, lower education levels, lower economic participation, and higher poverty rate in comparative terms to people without disabilities. For disabilities people achieve better, more long-lasting prospects, we must empower these people and remove barriers that restrict them from participating in the community have access to quality education, to find decent work and have their voices heard. In statistical terms, a very useful alternative that can provide support and monitoring of public policies in this area is proposing to be used continuously. A risk index called risk index disabled person who is to assess which factors are associated to this risk, as well as the intensity and direction of each of these factors, yielding a final score that can be sorted or classified according to the probability of people acquire a certain disability. In the Brazilian case, we propose the use of techniques such as binary and ordinal logistic regression to select the most significant factors using criteria such as AIC, BIC and DIC. Calculate the risk probability for different disabilities (see, hear, move and intellectual) and number of disabilities to the dataset Sample of respondents for Full Questionnaire at IBGE 2010 Census. In this work, by using stereotype ordinal logistic model with ordinal response, it was possible to improve the fit quality, to be compared with binary response logistic model. By using ordinal response merged the disability risk for different severity degree and amount of deficiencies. Mains conclusions were: i)the model required a smaller number of explanatory variables was intellectual or mental and greater number was disabilities; ii) the most sensitive adjust was using stereotype ordinal logistic; iii) different disabilities aren´t homogenous as the different predictor variables, and finally; iv) higher incidence of risks were noted visual disability, living in the northeast, female, age 80, yellow race, instruction level until incomplete fundamental, works production form their own consumption and high number of children.

Published: March 2018

Various type of soils have been identified based on their electrical and magnetic properties, especially with regards to peat soils. Peat soils are commonly considered as partly decomposed vegetation. In this study, electrical and magnetic properties have been used in K-means clustering to identify layers of peat soils. K-means clustering is a partitioning method that treats observations in the data. Data cores were obtained at every centimeter and examined for their electrical conductivity (σ) and magnetic susceptibility (χm) properties. A 291 cm core was obtained at Tegal Arum Village in South Kalimantan, Indonesia. The K-means clustering results indicate two different layers at 148 cm, and this is supported by loss on ignition (LOI) measurements. In the first layers, a 87.65% LOI was found associated with peat soils (above 248 cm). Whereas, in the second layers, there was a 26.11% LOI associated with mineral soils (below 248 cm). The results of this study using K-means clustering can be used to delineate soil layers.

This study examines whether information about the winners of the Sustainability Reporting Award (SRA) contributes to the usefulness of the information in the financial statements. This study used a sample consisting of 110 winners of SRA (SRA firms) and 110 companies that did not receive SRA (non-SRA firms) from 2008 to 2016. The study found that earnings per share (EPS), book value per share (BVPS), and earnings per share change (EPSC) are value relevant information. Results of comparison between SRA firms and non-SRA fimrs, this study found that EPS positive association with stock price and with returns for SRA firms is higher than that for non-SRA firms. Findings of this study also show that, value relevance of BVPS for non-SRA firms is higher than that for SRA firms. When mesures of Price and BVPS are transformed into natural logarithm, the value relevance of BVPS for SRA firms is higher than that for non-SRA firms. Thus, the results are sensitive to measures of the variables. The findings of this study indicate that information about the winners of SRA contributes to the usefulness of financial statements.

A novel abrasive-free planarization method named catalyst-referred etching (CARE) was developed. A polishing pad is coated with a catalytic material to promote chemical etching of the work substrate. During processing, the topmost areas of the work substrate, which are in contact with the catalyst surface, are selectively etched off. Atomically highly ordered surfaces are obtained for many types of work substrates. In this paper, the removal characteristics and mechanism of CARE for single crystalline 4H-SiC are reviewed.

The polishing of 4H-SiC wafer processed under ultraviolet (UV) irradiation was investigated to verify the phenomena and effectiveness of ultraviolet-ray aided machining (U-RAM). Inductively coupled plasma spectrometry (ICPS) analysis was conducted to quantitatively determine the oxidation/dissolution volume of SiC. X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS) were used to qualitatively analyze the 4H-SiC surfaces. These analyses were used to clarify the compounds that are formed/removed by the decomposition of cathilon dye and water during the polishing of 4H-SiC using TiO2-, cathilon- and TiO2-cathilon (mixed) slurries, all of which contained diamond particles. ICPS measurements indicate that a small amount of Si dissolves in aqueous solutions of cathilon- and TiO2-cathilon. XAS and XPS measurements indicate that SiC composes the bulk of the as-received 4H-SiC, and the surface and thin surface form an interface oxide inside SiC. The chemical-mechanical polishing of 4H-SiC using the TiO2-cathilon slurry forms an oxide, interface oxide, oxynitride and nitride. Diamond particles easily remove these compounds by mechanical scratching. It is possible to attain smaller surface roughness and higher polishing efficiency by combination with chemical reaction of TiO2-cathilon slurry and mechanical action of diamond particles under UV irradiation.

Published: March 2018

This study was conducted to compare the use of two types of feed on production performances of laying hen (feed consumption, egg production, feed conversion ratio, and population depletion) in Blitar Regency. Data were collected from several laying hen farms in Blitar Regency with survey method. All data were then analyzed both qualitatively and quantitatively. The average feed price of semi self-mixed feed and total self-mixed feeds were Rp 5,031 and Rp 4,752 per kg. Hen received semi self-mixed feed in one period showed 117.5 g/hen/day of feed intake, 70.38% of egg production, 2.62 of feed conversion ratio, and 20.50% of population depletion. Meanwhile, the total self-mixed feed resulted 118.23 g/hen/day of feed consumption, 71.75% of egg production, 2.39 of feed conversion ratio, and 15.94 of population depletion in one period. The proximate analysis showed that the total self-mixed feed had better nutrient balance compared to semi self-mixed feed, based on SNI 01-3929-2006 standard. As conclusion the total self-mixed feed showed more optimal production performances than semi self-mixed feed.

This study was conducted to find the best linear regression equation to estimate the body weight (BW) of female Bali cattle in Banyumulek Techno Park, West Nusa Tenggara based on three morphometric parameters, i.e. withers height (WH), body length (BL), and heart girth (HG). Data collection was conducted by random sampling of female Bali cattle (1-5 years of age) in Banyumulek Techno Park. A total of 63 female Bali cattle were used in this study. The parameter of WH (distance from the ground level to the highest point of withers) and BL (distance from the shoulder joint (later tuberosity of humerus) to the pelvic bone) were measured with a measuring stick. The HG data (circumference around the chest at the fourth rib) was measured with a measuring tape. Identification of age was carried out based on the animal recording book and incisors condition. The descriptive statistic analysis (mean value, standard deviation, the coefficient of variation, minimum and maximum value) of the morphometric and BW data were performed using MS Excel 2017 program. The linear regression equation analysis and the comparison between actual and estimated BW values (Independent sample T-test) were performed using SPSS 16.0 program. The BL and BW parameters had the highest correlation coefficient (r) value (0.86). The test result showed that the predicted BW value of female Bali cattle was not significantly different with the actual BW when using G model of linear regression equation (three variables used). The G model of linear regression equation had the highest R2 value (0.84). However the R2 value in the F model with two variables (BL and HG) was also high (0.83). It can be concluded that the simple linear regression equation BW=(0.96)(WH)+(1.26)(BL)+(1.57)(HG)-284.92 are the best model to estimate the BW value of female Bali cattle in Banyumulek Techno Park.
