    Complaints delivered directly to a firm will not be a problem if they can be handled properly, while the ones that are not disclosed directly to the firm but to a third party or even warnings to others not to use particular products or services, will be negative word-of-mouth communication. It can damage the image of the firm and be very detrimental. The purpose of this study was to analyze the antecedents of intention to engage in negative online word-of-mouth communication that includes dissatisfaction, service importance, success of complaint, complaint benefit, self confidence, altruism, retaliatory intention, and complaint cost. Medical services were selected considering the impact caused by the negligence of the service provider possibly giving rise to negative word-of-mouth communication. The online environment has been considered because of the developments in technology which provide opportunities for consumers to communicate with ach other. In addition, the dissemination of information through online media can spread incredibly widely and rapidly. The samples in this study comprised consumers of medical services who had disappointing experiences in using those services either directly or indirectly. A total of 123 questionnaires were analyzed with multiple regression analysis to test the research hypothesis. The results showed that the factors influencing the intentions behind negative online word-of-mouth communication were success of complaint, altruism, retaliatory intention, and complaint cost.

    The aim of the study is to investigate condition and reproductive activity of Donggala cattles during post-puberty and post-partom periods. The study was carried out for 12 months at Donggala, Palu and Sigi Districts where major populations of Donggala cattles were kept by farmers. A total of 200 heads of Donggala cattles belonged to the local farmers were sampled. The animals were categorized as heifers when they were 10 – 18 months old and cows at 18 – 24 months old. Data colected inthis study were from structured interview and direct observation. Variables measured were body condition score, live body weight, age of puberty, age of first estrus and first mating, days open, service per conception rate, non return rate and conception rate either during post puberty or post partum. Data found in this study were describe descriptively. The results of the study indicated that the age of puberty was late as live body weight body condition score of Donggala were low. First mating of Donngala heifers was much dependant upon live body weight. Heavier cattles tended to mat earlier than the lighter cattles. Heavier catlles had better service per conception rate, non return rate and conception rate either at post puberty or post partum periods. In conclusion, the cows with high body weight had earlier first estrus, first mating and better service per conception rate, non return rate and conception rate than those cows with low live body weight.

    The article aims to discuss teaching effectiveness in relation to teacher demographic factors like teachers’ age and teachers’ gender among Secondary School teachers in Calabar Education Zone of Cross River State, Nigeria. To achieve this aim, two hypotheses were stated and tested. These variables have important role to evaluate teachers’ effectiveness as scholarly proven through literatures. The descriptive survey design was adopted for use. The sample consist of one hundred and sixty-four (164) teachers and three hundred and twenty-eight (328) student from the Calabar Education Zone. Teachers’ Demographic Factors Questionnaire (TDFQ) and Teaching Effectiveness Questionnaire (TEQ) were developed by the researcher and validated by experts in Sociology of Education and Test/Measurement. The descriptive statistics, one-way analysis of variance, a post-hoc scheffe &amp; independent t-test were used. The result revealed that teachers’ age and gender significantly influence teaching effectiveness. Based on the findings, it is recommended among others that Government should see teachers age as an asset thereby put in more resources to train them so that they will be of benefit to the students and the society at large

    Switchgrass Biomass Composition Altered by Six Generations of Divergent Breeding for Digestibility

    Biomass composition of switchgrass (Panicum virgatum L.) can affect its utilization by ruminants and its conversion to liquid fuels in a biorefinery. The objective of this study was to evaluate the effects of six generations of divergent breeding for forage in vitro dry matter digestibility (IVDMD) on switchgrass biomass composition, forage quality traits, and ethanol yield. Initially there was one cycle of selection for both low (C-1) and high IVDMD (C1 = cv. Trailblazer), followed by four additional breeding cycles for high IVDMD. In cycles 4 and 5, winter survival was included as a selection criterion because of decreased winter survival of the C3 population. The experimental populations that were produced by these breeding generations and nine half-sib families from cycle 5 were evaluated for two post-establishment years at the research station in eastern Nebraska, where all the breeding work was conducted. The six breeding generations resulted in significant differences among the populations for all the 28 cell wall and non-cell-wall composition variables measured, forage quality, and ethanol yield traits measured except for total biomass C, cell wall concentration, soluble glucose, and etherified ferulates. These traits included all cell wall and nonstructural carbohydrates. Breeding for the heritable complex trait IVDMD affected a large number of plant biomass characteristics and also adversely affected plant biomass yield and winter survival

    Ethanol yields and cell wall properties in divergently bred switchgrass genotypes

    Genetic modification of herbaceous plant cell walls to increase biofuels yields is a primary bioenergy research goal. Using two switchgrass populations developed by divergent breeding for ruminant digestibility, the contributions of several wall-related factors to ethanol yields was evaluated. Field grown low lignin plants significantly out yielded high lignin plants for conversion to ethanol by 39.1% and extraction of xylans by 12%. However, across all plants analyzed, greater than 50% of the variation in ethanol yields was attributable to changes in tissue and cell wall architecture, and responses of stem biomass to diluteacid pretreatment. Although lignin levels were lower in the most efficiently converted genotypes, no apparent correlation were seen in the lignin monomer G/S ratios. Plants with higher ethanol yields were associated with an apparent decrease in the lignification of the cortical sclerenchyma, and a marked decrease in the granularity of the cell walls following dilute-acid pretreatment

    Three crops of warm-season grasses are being developed for biomass production on northern rain-fed marginal farmland: big bluestem (BBS), switchgrass (SG), and a low diversity mixture of grasses (LDM). In this study, biomass harvested from established fields were compared for pelletization and subsequent conversion to sugars and ethanol. Each biomass was successfully pelletized to similar bulk densities without adding a binder at a commercial feed operation. Pelletizing increased the bulk density by 407% on average and was equally effective on all three biomass samples (528–554 kg/m3). Chemical analysis of the samples indicated that glucan and xylan contents were slightly reduced during pelletizing (by 23 and 16 g/kg, respectively), as well as theoretical ethanol yields, which are based upon total carbohydrate contents. Pellets and milled straws were pre-treated with either liquid hot-water or low-moisture ammonium hydroxide (LMA) and subsequently hydrolyzed with cellulases. Glucose and total sugar yields were similar for non-pellets and pellets using either pre-treatment; carbohydrates present in pellets were more efficiently recovered compared to non-pellets. LMA pretreated samples were separately hydrolyzed and fermented to ethanol using Scheffersomyces stipitis yeast. Hydrolysis recovered 69.7–76.8% of the glucose and 66.5–73.3% of the xylose across all samples. Glucose yields were 251–279 g/kg, db and were significantly lower for SG as compared to the other biomass samples. Recovered sugars were fermented to ethanol at 77.7–86.7% of theoretical yield. Final ethanol yields (245.9–275.5 L/Mg, db) were similar for all of the grasses and estimated to equate to production levels for BBS, LDM, and SG of 1,952, 2,586, and 2,636 l of ethanol per ha, respectively
