    Regardless of the growing importance of communication skills as a core clinical competence, few studies have determined the effects of communication skills courses in undergraduate medical curricula in Asian medical schools. The purpose of this study was to examine the effectiveness of a communication skills program for preclinical medical students. A communication skills course was provided to 111 second-year medical students in a medical college in Korea. Students' self-assessed competency of communication skills was evaluated by a questionnaire survey. To examine the improvement in observed communication skills, the students' encounters with standardized patients (SPs) were assessed at the first session and at the final course assessment. A structured checklist, consisting of 25 communication skills items, was used for the assessment. Students' self-assessed competency of communication skills increased significantly after completion of the course (pcommunication skills scores also improved significantly at the end of the course; the mean scores of the first SPs encounters was 49.6 (standard deviation [SD], 11.1), and those of cases A and B at the final assessment were 61.5 (SD, 8.4) and 69.6 (SD, 7.8), respectively (F61=269.54, pcommunication skills course was beneficial in developing and improving communication skills competency in preclinical medical students. Further studies should be followed to examine whether the acquisition of communication skills during preclinical studies can be sustained into clerkship and actual practice.

    2014-01-01

    Mycobacterium avium ssp. paratuberculosis (MAP) can be present in cow milk and low numbers may survive high-temperature, short-time (HTST) pasteurization. Although HTST treatment leads to inactivation of at least 5 log10 cycles, it might become necessary to enhance the efficacy of HTST by additional treatments such as homogenization if the debate about the role of MAP in Crohn's disease of humans concludes that MAP is a zoonotic agent. This study aimed to determine whether disrupting the clumps of MAP in milk by homogenization during the heat treatment process would enhance the inactivation of MAP. We used HTST pasteurization in a continuous-flow pilot-plant pasteurizer and evaluated the effect of upstream, downstream, and in-hold homogenization on inactivation of MAP. Reduction of MAP at 72°C with a holding time of 28s was between 3.7 and 6.9 log10 cycles, with an overall mean of 5.5 log10 cycles. None of the 3 homogenization modes applied showed a statistically significant additional effect on the inactivation of MAP during HTST treatment. Copyright © 2014 American Dairy Science Association.

    Full Text Available Background and Aim: Kombucha tea is made through fermentation of sweet tea by Kombucha fungus. It has beneficial therapeutic effects in the treatment of many diseases. The present study aimed at examining the effect of Kombucha tea extract on blood sugar and blood lipid profiles in diabetes. Materials and Methods: Twenty-eight Wistar rats weighing about 250g were divided into 4 equal groups and then injected intraperitoneally (IP with alloxan to induce diabetes. The administered concentrations were 20 and 80 mg/kg of Kombucha tea and 20 mg/kg of black ordinary tea for one month. The rats’ blood sugar and weight were tested before and after the intervention period but blood lipid parameters per either administration were also assessed at the end of the period. Results: Mean blood sugar in the diabetic rats receiving Kombucha tea was reduced. Maximum reduction in blood sugar was observed in the group receiving Kombucha tea with concentration of 80 mg/kg. However, black tea significantly reduced blood sugar. Conclusion: Kombucha tea consumption for a month only reduced blood sugar levels in diabetic patients. But increased the weight and not have favorable effects on lipid profile.

    Full Text Available Aim of study: The inoculation of forest seedlings with ectomycorrhizal fungi can improve the morphological and physiological qualities of plants, especially those used for regeneration of arid areas. Rhizopogon roseolus is an ectomycorrhizal fungus (ECM commonly used for reforestation. In this study, the specific objectives were to know some morphophysiological effects of Rhizopogon Roseolus on Pinus halepensis seedlings under standard nursery conditionsArea of study: ETSI Montes and EUIT Forestal, Madrid.Material and Methods: In nursery, under well watered conditions and peat growing substrates, Aleppo pine seedlings were inoculated with R. roseolus. Five months after the inoculations, we examined the growth, water parameters (osmotic potential at full turgor [Ψπfull], osmotic potential at zero turgor [Ψπ0], and the tissue modulus of elasticity near full turgor [Emax], mycorrhizal colonization, and concentration and content of macronutrients in the seedlings. Subsequently, a trial was conducted to assess the root growth potential.Main results: The mycorrhization decreased the height and diameter of mycorrhizal seedlings but increased the root weight and root branching. R. roseolus did not cause any significant effect on the regeneration of new roots or on any of the tested hydric parameters, but it did improve N uptake of the seedlings.Research highlights: The mycorrhizal inoculation increased the N uptake. The mycorrhizal inoculation caused opposite effects on some growth parametersKeywords: Osmotic adjustment; elastic adjustment; mineral nutrition; root growth potential; nursery; Rhizopogon roseolus;  Pinus halepensis.

    The data set consisted of 1,016,856 inseminations of 191,012 first, second, and third parity Holstein cows from 484 farms. Data were collected from year 2001 through 2007 and included meteorological data from 35 weather stations. Nonreturn rate at 56 d after first insemination (NR56) was considered. A logit model was used to estimate the effect of temperature-humidity index (THI) on reproduction across parities. Then, least squares means were used to detect the THI breakpoints using a 2-phase linear regression procedure. Finally, a multiple-trait threshold model was used to estimate variance components for NR56 in first and second parity cows. A dummy regression variable (t) was used to estimate NR56 decline due to heat stress. The NR56, both for first and second parity cows, was significantly (unfavorable) affected by THI from 4 d before 5 d after the insemination date. Additive genetic variances for NR56 increased from first to second parity both for general and heat stress effect. Genetic correlations between general and heat stress effects were -0.31 for first parity and -0.45 for second parity cows. Copyright © 2016 American Dairy Science Association.

  17. Short communication: Effect of active food packaging materials on fluid milk quality and shelf life.

    2014-01-01

    Active packaging, in which active agents are embedded into or on the surface of food packaging materials, can enhance the nutritive value, economics, and stability of food, as well as enable in-package processing. In one embodiment of active food packaging, lactase was covalently immobilized onto packaging films for in-package lactose hydrolysis. In prior work, lactase was covalently bound to low-density polyethylene using polyethyleneimine and glutaraldehyde cross-linkers to form the packaging film. Because of the potential contaminants of proteases, lipases, and spoilage organisms in typical enzyme preparations, the goal of the current work was to determine the effect of immobilized-lactase active packaging technology on unanticipated side effects, such as shortened shelf-life and reduced product quality. Results suggested no evidence of lipase or protease activity on the active packaging films, indicating that such active packaging films could enable in-package lactose hydrolysis without adversely affecting product quality in terms of dairy protein or lipid stability. Storage stability studies indicated that lactase did not migrate from the film over a 49-d period, and that dry storage resulted in 13.41% retained activity, whereas wet storage conditions enabled retention of 62.52% activity. Results of a standard plate count indicated that the film modification reagents introduced minor microbial contamination; however, the microbial population remained under the 20,000 cfu/mL limit through the manufacturer's suggested 14-d storage period for all film samples. This suggests that commercially produced immobilized lactase active packaging should use purified cross-linkers and enzymes. Characterization of unanticipated effects of active packaging on food quality reported here is important in demonstrating the commercial potential of such technologies.

    2014-06-01

    The aim of this research was to study the effect of soybean meal (SBM) heat procedures on growth performance of broiler chickens. A trial was carried out using 200 male Ross 308 strain chickens during 3 feeding periods (starter, grower and finisher, 42 days). The experiment was based on a completely randomized design with 5 treatments giving 4 replications of 10 broilers per treatment. Treatments consisted on: T1 (control, un-processed SBM), T2 (autoclaved SBM: 121 degree centigrade, 20 min), T3 (autoclaved SBM: 121 degree centigrade, 30 min), T4 (roasted SBM: 120 degree centigrade, 20 min) and T5 (microwaved SBM: 46 degree centigrade, 540 watt, 7 min). Growth performance of animals was examined by determining body weight (BW), body weight grain (BWG), feed intake (FI) and feed conversion rate (FCR). Higher BW (p<0.05) and BWG (p<0.05) and lower FCR (p<0.05) were found in broiler chickens fed heat processed SBM diets compared to those fed a raw SBM diet, probably due to higher nutrient availability. However, no differences were found among heat SBM procedures (autoclaving, roasting and microwaving) on growth performance of animals for the starter, grower and finisher periods. From the results of this experiment, it is concluded that further research needs to be developed to establish the effect of temperature-time heat procedures on nutritive value of SBM in terms of levels of anti-nutritional factors (trypsin inhibitor activity and phytic acid) and amino acids profile and its influence on growth performance of broilers.

    Because residual antibiotics in dried distillers grains with solubles (DDGS) could lead to inadvertent feeding of antibiotics to animals, the objective of our study was to determine if a commercial DDGS contained antibiotics. The DDGS used in a feeding study, and milk from cows fed the DDGS, were below the detection limits for at least 17 antibiotics. Additionally, we evaluated if DDGS had any antimicrobial effect against Salmonella Typhimurium, Listeria innocua, Escherichia coli ATCC 25922, Staphylococcus aureus, Pediococcus acidilactici, Lactobacillus casei, Lactobacillus acidophilus, Bacillus licheniformis, Paenibacillus odorifer, Pseudomonas fluorescens, and Paenibacillus amylolyticus using the disk diffusion seeded agar overlay method. Neither the buffered nor nonbuffered water-soluble fractions of DDGS yielded clear zones around disks, indicating that the water-soluble DDGS fraction had no antimicrobial properties against any of the microorganisms tested. The absence of antibiotic residues in DDGS and milk samples in this study confirmed that this source of DDGS can be used as livestock feed without fear of inadvertent feeding of antibiotics.

    Field experiments were conducted to characterize the effects of deficit irrigation on curly lettuce (Lactuca sativa var. Crispa cv. Bohemia) evapotranspiration, water use efficiency, marketable yield, yield components and mineral contents. The experiments were performed under semiarid climatic conditions in Erzurum province (east of Turkey) in the summer periods of 2005 and 2006. Irrigation water levels were selected to be 100% of usable soil water in full irrigation treatment (control) (T-100) and 80%, 60%, 40% and 20% of usable soil water in deficit irrigation treatments (T-80, T-60, T-40 and T- 20, respectively). Average seasonal evapotranspiration was 232 mm in T-100 and 121 mm in T-20. Average marketable yield was 39.49 Mg ha{sup -}1 in T-100 and 14.57 Mg ha{sup -}1 in T-20. A linear relationship (y=0.23x-13.97; R{sup 2}0.94) was found between seasonal evapotranspiration (x) and marketable plant yield (y). According to the regression equation, the yield response factor (k{sub y}) was found to be 1.39, and the coefficient of determination 0.91. Average water use efficiency was 168.88 kg ha{sup -}1 mm{sup -}1 in T-100 and 117.39 kg ha{sup -}1 mm{sup -}1 in T-20. The lowest plant length, width, steam diameter, leaf number, macro and micro element content values were obtained for T-20 in both years. (Author) 21 refs.

    Communication methods based on lasers as carrier are well known. In our work we have made a two way laser based communication system for short range (<2 Km) line of sight communication. A small piece of plane mirror (100% reflector) was mounted on the centre of a speaker cone. The speaker was positioned close to the opening of laser such that He-Ne laser beam (10 mW) after reflection from the mirror is directed towards the receiver. There is a pre-amplifier and an amplifier between a microphone and the speaker. When the diagram of the speaker vibrates, it positionally modulates the laser beam. On the receiving end, there is a photo diode, a pre-amplifier, an amplifier and a head phone. So the man on the receiving end can decode the sound signal. On each stage there is a transmitter and a receiver assembled close to each other. So the two way communication is possible in the range 20 to 20 Khz. (author)

    The verbal communication represents the first human communication, that even more used and one most immediate. History and the development of communication is divided into historical periods, is complex and is bound to the period contingencies and to the social reference community. The oral communication is never isolated but is always taken by the not verbal one, including the silences, the position and the spaces (c.d. proxemics). The good communicator stimulates the cooperation through the conversation rule respect (qualities, amounts, way and relation) and reduces the possible asymmetry between broadcaster and receiver fitting its code to that of the interlocutor.

    The cooling rate of raw milk may influence sensory properties and pasteurized shelf life. Under the Pasteurized Milk Ordinance for grade A milk, raw milk may be cooled instantaneously by on-farm heat exchangers but is also acceptable if "cooled to 10°C or less within four (4) hours of the commencement of the first milking." The objective of this study was to determine the effect of raw milk cooling on consumer perception and shelf life. Raw milk (18-21°C) was obtained and transported within 1h of milking to North Carolina State University (Raleigh). The batch of raw milk was split in 2 portions, and a plate heat exchanger was used to quickly cool one portion to <6°C within 1min. The second portion was stored in a jacketed bulk tank and slowly cooled over 4h to <10°C. Milk from 3 consecutive milkings was collected every 12h, with subsequent milkings added to the previous collections. The bulk milk was kept below 10°C while adding milk for the slow cool milk treatment. After 72h, each whole milk was separated; the skim milk was pasteurized at 73 or 78°C for 20 s, homogenized, and held at 4°C. Difference tests (n=75) and consumer acceptance tests (n=100) were conducted to determine if consumers could detect differences among milks. Descriptive analysis and microbial testing for aerobic, psychrotrophic, and psychrotolerant spore counts were conducted through shelf life. The entire experiment was repeated in triplicate. Raw milks averaged 3.3 logcfu/mL by aerobic plate count, <25cfu/mL coliforms, somatic cell count of 300,000 cells/mL, and 3.15±0.07% protein. Psychrotolerant spores were not found in the raw milk. Consumers could not detect differences between cooling treatments of the same pasteurization temperature or between different temperatures of the same cooling treatment. Milks reached sensory failure 49±4d on average after processing, and aerobic counts were between 5 to 7 logcfu/mL. Cooling treatment had no effect on shelf life. These results suggest

    Full Text Available The aim of the present study was to determine whether any combination of buck effect and melatonin treatment could improve reproductive performance in Payoya female goats during early postpartum. Forty-four pregnant female goats were used. After birth in spring, they were distributed into two major groups: females submitted to the buck effect (BE, N=22 or not such effect (NBE, N=22. In turn, the BE animals were subdivided into: 1 no further treatment (CBE, N=11 and 2 implanted with melatonin (MELBE, N=11. And the NBE animals were subdivided into: 3 no further treatment (CNBE, N=12 and 4 implanted with melatonin (MELNBE, N=10. Melatonin was implanted 10 days after birth. Oestrus activity was tested daily using entire males from day of birth (D0 in the groups NBE and from D55 after birth in the BE groups. Transrectal ultrasonography was performed 10 days after the detection of oestrus and 45 days after mounting to determine pregnancy. Fecundity, fertility and productivity were higher in MELBE animals compared to CNBE animals (fecundity and fertility: 66.7% vs. 0.0%, and productivity: 0.73 vs. 0.00 kids/female for MELBE and CNBE respectively, p<0.05, and CBE animals (fecundity and fertility: 66.7% vs. 14.3%, and productivity: 0.73 vs. 0.09 kids/female for MELBE and CBE respectively; p<0.05. No significant differences were recorded between the subgroups of the NBE animals. The present results show that exogenous melatonin improves the reproductive performances of early post-partum Payoya does exposed to male effect during the seasonal anoestrus.

    The present study was conducted to evaluate the effects of different processing methods of barley grain in starter rations on feed intake, average daily gain, feed efficiency, skeletal growth, fecal score, and rumen pH of dairy calves. Thirty-two Holstein dairy calves (16 female and 16 male) were randomly allocated to 1 of 4 treatments consisting of coarse ground, whole, steam-rolled, or roasted barley from d 4 to 56 of birth in a completely randomized design. Starter diets were formulated to have similar ingredients and composition. All calves had free access to water and feed throughout the study period and received 4 L of milk/d from a bottle from d 4 to 41, 2L/d from d 41 to 45, and weaning occurred on d 45. Feed intake and fecal score were recorded daily. Body weight and skeletal growth measures were recorded on d 4 (beginning of the study), 45, and 56. Rumen fluid and blood samples were collected on d 35, 45, and 56. Data were analyzed using PROC MIXED of SAS (SAS Institute Inc., Cary, NC). The results indicate that different methods of processing barley had no detectable effect on dry matter intake, average daily gain, and feed efficiency and that skeletal growth, health, and rumen pH were not affected by dietary treatments. In conclusion, the results show that different processing methods of barley included in starter diets had no detectable effect on the performance of dairy calves under our experimental conditions. Therefore, feeding whole or coarsely ground barley would be a more economical method compared with steam rolled or roasted barley. Copyright © 2013 American Dairy Science Association.

    Maternal heat stress alters immune function of the offspring, as well as metabolism and future lactational performance, but its effect on the hormonal and metabolic responses of the neonate immediately after birth is still not clear. The objective of this study was to investigate the blood profiles of hormones and metabolites of calves born to cows that were cooled (CL) or heat-stressed (HS) during the dry period. Within 2 h after birth, but before colostrum feeding, blood samples were collected from calves [18 bulls (HS: n=10; CL: n=8) and 20 heifers (HS: n=10; CL: n=10)] born to CL or HS dry cows, and hematocrit and plasma concentrations of total protein, prolactin, insulin-like growth factor-I, insulin, glucose, nonesterified fatty acid, and β-hydroxybutyrate were measured. Compared with CL, HS calves had lower hematocrit and tended to have lower plasma concentrations of insulin, prolactin, and insulin-like growth factor-I. However, maternal heat stress had no effect on plasma levels of total protein, glucose, fatty acid, and β-hydroxybutyrate immediately after birth. These results suggest that maternal heat stress desensitizes a calf's stress response and alters the fetal development by reducing the secretion of insulin-like growth factor-I, prolactin, and insulin.

    The effect of fat supplements (FS) providing different proportions of saturated (SFA) and unsaturated (UFA) fatty acids on supply, apparent ruminal synthesis (ARS), and duodenal flow (DF) of some B vitamins (thiamine, riboflavin, niacin, vitamin B 6 , folates, and vitamin B 12 ) were evaluated in an experiment using 8 ruminally and duodenally cannulated lactating Holstein cows. The experiment was a replicated 4 × 4 Latin square design with 21-d treatment periods. The 4 treatments were a control diet without fatty acid supplement and 3 diets with 2.5% additional fatty acids from supplements containing (1) SFA, (2) an intermediate mixture of SFA and UFA, or (3) UFA. All diets were served as a total mixed ration once daily at 115% of the expected intake. B-vitamin concentrations were analyzed in feed and duodenal digesta. Apparent ruminal synthesis of each B vitamin was calculated as the DF minus the intake. B-vitamin concentrations were similar among the 4 treatments; consequently, daily intake of the vitamins followed the same pattern as dry matter intake. Adding FS decreased B-vitamin intakes (except vitamin B 12 ), as did increasing the proportion of UFA. Riboflavin and niacin DF and ARS, expressed as total daily amount or per unit of dry matter intake, were not affected by FS, but increasing the proportion of UFA decreased riboflavin and niacin DF and ARS. Fat supplements decreased DF of vitamin B 6 , expressed either as total daily amount or per unit of dry matter intake. No treatment effects were observed on total daily folate DF and ARS. However, when expressed per unit of dry matter intake, folate DF and ARS were greater when cows were fed FS and they increased linearly with the proportion of UFA in the supplement. Inclusion of fat supplements into the dairy cow diet had a limited effect on the fate of most B vitamins in the rumen although increasing the proportion of UFA in the FS linearly decreased apparent synthesis of riboflavin and niacin in the rumen

    The strong ropy character of the Scandinavian fermented milk viili is conferred by the exopolysaccharides (EPS) produced by lactococcal strains. These biopolymers can be responsible for some health benefits. We have assessed the influence of the EPS fraction isolated from commercial viili on the adhesion of some probiotics and pathogens to human intestinal mucus. Concentrations of viili EPS greater than 0.1 mg/mL promoted a decrease in adherence of Bifidobacterium lactis Bb12 and Lactobacillus rhamnosus GG and this effect was dose-dependent. However, no modifications were detected on the adhesion levels of the pathogenic strains tested at a concentration of 1 mg/mL of EPS. Results obtained in the present work should be considered in the design of new probiotic products.

    Conjugated linoleic acids (CLA) are well known as milk fat-reducing feed supplements in diets for lactating ruminants. However, their effects on milk concentrations of fat-soluble vitamins are unknown. This study was performed to investigate the hypothesis that CLA affect the concentrations of retinol and tocopherol in ewe milk. For that purpose, group-housed Merino ewes (101 ± 13.7 kg) nursing twin lambs and fed with a hay:concentrate diet were supplemented with either 45 g of a rumen-protected CLA supplement containing 3.4 g of cis-9,trans-11-CLA and 3.4 g of trans-10,cis-12-CLA (CLA group, n=11) or with 45 g of a hydrogenated vegetable fat (control group, n=12) per ewe per day during the first 6 wk of lactation. Feed intake was recorded daily (concentrate) or weekly (hay) per group. Milk spot samples were collected at the beginning of the experiment (5 ± 2.4 d postpartum) and then weekly after lambs had been separated for 2 h from their mothers. The milk fat content was determined and feed and milk were analyzed for concentrations of α-, γ-, and δ-tocopherol and for retinol by HPLC. Dietary intake of tocopherol and retinol was similar in both groups. Feeding CLA decreased milk fat concentration by 23% on average, and during the first 3 wk of the study milk tocopherol concentration tended to be increased by feeding CLA (+17%), but retinol concentrations were not influenced. When related to milk fat, CLA feeding significantly increased both milk tocopherol (+40%) and retinol (+32%) and these effects were evident during the whole experimental period corresponding to the first half of lactation.

    Kefir is a fermented milk traditionally made from a unique starter culture, which consists of numerous bacteria and yeast species bound together in an exopolysaccharide matrix produced by certain lactic acid bacteria. Many health benefits are associated with traditionally produced kefir; however, bulging and leaking packaging, caused by secondary yeast fermentation during storage, has limited large-scale manufacture. Commercial kefir products have been designed to reduce these effects by using a pure starter culture consisting of a mixture of bacteria and yeast species that give a flavor similar to traditional kefir, but some health benefits may be lost in commercial production due to reduced microbial diversity and lack of beneficial exopolysaccharides. In this study, traditional and commercial kefir was frozen to study the effects of frozen storage on the viability of probiotic bacteria over time. Traditional kefir was prepared by inoculating 1L of pasteurized whole goat milk with approximately 30g of kefir grains. Commercial kefir was prepared by inoculating 1L of full-fat, pasteurized goat milk with a commercial kefir starter. The milk was allowed to ferment at room temperature (24-28°C) until pH 4.6 was reached. Samples were frozen (-8 to -14°C) immediately following the completion of fermentation and were thawed and plated for lactobacilli, lactococci, and yeasts on d 0, 7, 14, and 30 of frozen storage. Lactobacilli, lactococci, and yeasts were significantly reduced in number during frozen storage; however, the traditionally produced kefir was shown to have significantly higher counts of bacteria and yeast at each sampling. We concluded that frozen storage and the development of frozen kefir products could eliminate most packaging concerns associated with the large-scale manufacture of traditionally produced kefir, resulting in increased production and marketability of this healthful product.

    Heat stress (HT) during the dry period compromises mammary gland (MG) growth, thus negatively affecting subsequent milk yield. Cooling during the late dry period, when mammary tissue proliferates, is a common management practice. However, it neglects MG involution during the early dry period, a process that is accomplished by both apoptosis and autophagy. Our objective was to evaluate the effect of HT on MG autophagy during the early dry period. Holstein cows were dried off ~45d before expected calving and randomly assigned to 1 of 2 treatments: HT or cooling (CL). All cows were housed in the same free stall barn during the dry period, but only the stall area for CL cows was equipped with soakers and fans. Rectal temperature and respiration rate were measured daily during the dry period. Mammary gland biopsies were collected from each cow 3d before dry-off and on d 3, 7, 14, and 22±2 after dry-off. Autophagy in the MG was determined by measuring protein expression of 2 autophagic markers, autophagy-related protein 7 and microtubule-associated protein light chain 3 (LC3). The average temperature-humidity index during the dry period was 77.7, which indicated that HT and CL cows were exposed to significant heat stress. However, the cooling system effectively alleviated heat strain in CL cows by decreasing the rectal temperature (39.0 vs. 39.4°C) and respiration rate (47.3 vs. 71.2 breaths per minute) relative to HT cows. Protein expression of autophagy-related protein 7, a marker for early autophagosome formation, did not change within or between groups. In contrast, protein expression of LC3-II, a marker of autophagosomes, and its precursor LC3-I showed a dynamic expression pattern in MG from CL cows during the early dry period. Relative to HT cows, MG from CL cows displayed higher expression of LC3-I and LC3-II on d 7 and lower expression of LC3-II on d 14 and 22 after dry-off. Collectively, our data provide a possible mechanistic explanation for the impairment of

    The objectives of this study were to examine the behavioral effects of providing limit-fed dairy heifers an increased amount of feed bunk space compared with recommended feed bunk allowance, and to determine if the effects of provision of extra bunk space would be comparable to those seen when limit-fed heifers are provided a low-nutritive feedstuff. Twelve Holstein dairy heifers (381.1 ± 44.8 d of age, 417.3 ± 47.9 kg), divided into groups of 4, were exposed to each of 3 treatments using a 3 × 3 Latin square design with 7-d periods. The treatments were (1) 0.68 m of feed bunk space/heifer (TMR-0.68), (2) 0.34 m of feed bunk space/heifer (TMR-0.34), and (3) 0.34 m of feed bunk space/heifer with an additional 0.34 m of feed bunk space available for free-choice straw (TMR-S). The total mixed ration was fed once daily at a restricted level (1.83% of body weight) and contained (dry matter basis) 19.9% alfalfa/grass haylage, 20.1% corn silage, 49.6% high-moisture corn, and 10.4% protein supplement. Group dry matter intake (DMI) was recorded daily. Behavior at the feed bunk was recorded for the last 4 d of each treatment period. Due to the provision of straw, DMI was highest on the TMR-S treatment compared with the other treatments (9.4 vs. 7.8 kg/d). Heifers spent the most time feeding when on the TMR-S treatment (147.7 min/d), with no difference in feeding time between the limit-fed TMR treatments (64.5 min/d). Within the TMR-S treatment, feeding time on the straw was 76.9 min/d; thus, the rate of consumption of only the TMR was similar across all treatments. Unrewarded time at the feed bunk (when no feed was present) did not differ between treatments. Heifers did not differ in competitive behavior when on the limit-fed TMR treatments (13.1 displacements/heifer per day). However, while on the TMR-S treatment, heifers displaced each other more frequently (23.8 displacements/heifer per day) than while on the other 2 treatments. Overall, results suggest that neither

    The primary objective of this study was to determine the effect of straw inclusion levels on the feeding behavior of young, weaned calves adapted to a dry total mixed ration (TMR) composed of a multitextured concentrate and chopped straw. A secondary objective was to determine how developed feeding patterns persist after calves were switched to a conventional silage-based diet. Ten Holstein bull calves (91 ± 2.4d of age, weighing 136 ± 12.3 kg) were assigned to 1 of 2 treatments: a TMR containing [dry matter (DM) basis] either (1) 85% concentrate and 15% chopped straw for 10 wk (wk 1 to 10) or (2) 85% concentrate and 15% chopped straw for 5 wk (wk 1 to 5), then 70% concentrate and 30% chopped straw for 5 wk (wk 6 to 10). After 10 wk, all animals were transitioned to a TMR containing (DM basis) 42.3% corn silage and 57.7% haylage for 2 wk (wk 11 to 12). During wk 1 to 5, all calves had similar DMI (5.5 kg/d), average daily gain (1.7 kg/d), feed efficiency (3.5 kg of DM/kg of gain), and eating time (151.9 min/d). During wk 6 to 10, calves transitioned to the 70% diet ate less DM (5.5 vs. 7.4 kg/d), grew more slowly (1.3 vs. 1.6 kg/d), sorted more against long forage particles (62.8 vs. 103.8%), and had greater feeding times (194.9 vs. 102.6 min/d). The difference in feeding time occurred only during the first 8 h after feed delivery. Despite similar DMI (5.2 kg/d) and average daily gain (1.1 kg/d) in wk 11 to 12, differences in behavior were observed resulting from previous diets. In wk 11 to 12, calves previously fed the 70% diet continued to have a longer meal immediately after feed delivery. Overall, the results indicate that diluting a dry TMR containing a multitextured concentrate and chopped straw with more straw resulted in calves spending more time feeding and having longer meals immediately after feed delivery; this feeding pattern carried over after calves were transitioned to a silage-based ration.

    The use of caustic paste combined with a sedative is one of the least painful methods for disbudding. It is recommended to disbud at as early as 5d of age. However, the sedative xylazine reportedly causes a decrease in core temperature. Furthermore, young calves do not thermoregulate efficiently. We investigated the effects of disbudding calves at 5d of age using caustic paste and xylazine sedation on body temperature, activity, and milk intake of 46 individually housed 5-d-old calves in a 2×2 factorial design, with milk fed at 4.5L/d (low-fed calves) versus 9L/d (high-fed calves), with or without a heat lamp. Body temperature, calf activity (standing time), and barn temperature were monitored continuously using automatic data loggers on the day of, before the day of, and the day after disbudding. All calves were injected intramuscularly with 0.25mL of 2mg/mL xylazine 20min before disbudding (dose: 0.12±0.003mL/kg of BW). We found that the body temperature of 5-d-old calves decreased immediately after the injection of the sedative xylazine. The body temperature of calves decreased 0.9±0.09°C and it took 3.8±0.32h to climb back to the preinjection body temperature. Calves that were fed the lower amount of milk, received a higher dose of xylazine (mL/kg BW), or were disbudded in a colder environment were more affected by body temperature variations (lower and longest decrease in body temperature and higher magnitude). Calf activity recovery followed the pattern of body temperature recovery. Milk allowance and supplemental heat did not help enhance recovery during the 6h following the procedure. The disbudding procedure did not affect milk intake but calves with less body temperature decrease or kept in a warmer environment drank more milk following disbudding. Low-fed calves were overall more affected by the procedure than high-fed calves during the disbudding day and the following day (greater decrease in body temperature and drank less in the colder

    The role of fatty acid synthase (FASN) on de novo fatty acid synthesis has been well established. In monogastrics, unlike acetyl-coenzyme A carboxylase, FASN is primarily controlled at the transcriptional level. However, no data exist on ruminant mammary cells evaluating effects of FASN knockdown on mRNA expression of lipogenic genes. Inhibition of FASN in mammary cells by C75-mediated interference, a synthetic inhibitor of FASN activity, and short hairpin RNA-mediated interference markedly reduced cellular triglyceride content at least in part by decreasing the expression of genes related to triglyceride synthesis (GPAT, AGPAT6, and DGAT2) and enhancing the expression of lipolysis-related genes (ATGL and HSL). Consistent with the markedly lower expression of genes related to lipid droplet formation and secretion (TIP47, ADFP, BTN1A1, and XDH), cellular lipid droplets also were reduced sharply after incubation with C75 or adenovirus-short-hairpin-RNA. The results underscored the essential role of FASN in the overall process of milk-fat formation in goat mammary epithelial cells. Copyright © 2015 American Dairy Science Association.

    2015-01-01

    This brief analyzes the characteristics of a microring resonator (MRR) to perform communication using ultra-short soliton pulses. The raising of nonlinear refractive indices, coupling coefficients and radius of the single microring resonator leads to decrease in input power and round trips wherein the bifurcation occurs. As a result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n2=3.2×10−20 m2/W. Using a decimal convertor system, these ultra-short signals can be converted into quantum information. Results show that multi solitons with FWHM and FSR of 10 pm and 600 pm can be generated respectively. The multi optical soliton with FWHM and FSR of 325 pm and 880 nm can be incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum information is performed.

    2012-11-01

    The aim of this study was to investigate the effect of different feeding proportions of forage ?grazing vs. silage? on milk fatty acids (FA) profile and conjugated linoleic acid (CLA) content of autumn calving Holstein-Friesian cows (n = 61) at CIAM (Galicia, NW Spain). Three treatments (S, 100% silage; G/S, 50% grazing + 50% silage; G, 100% grazing) were set and milk FA profile of dairy cows was determined by gas chromatography-mass spectrometry. The G group showed a decrease in short (p < 0.05) and medium chain FA (p < 0.001), with an increase in long chain FA (p < 0.001) in comparison to the G/S and S groups, which showed the lowest levels (p < 0.001) of mono- and polyunsaturated FA. The CLA content in milk fat increased (p < 0.001) linearly in relation to the increased proportion of fresh grass in the diet of dairy cows from 0.49 and 0.82 to 1.14 g/100 g FA for the treatments S, G/S and G, respectively. During spring and summer, the levels of CLA were three times higher (p < 0.001, +0.76 g/100 g FA) in milk from dairy cows at the G group than in cows at the S group and twice higher (p < 0.001, +0.40 g/100 g FA) than in cows at the G/S group. High proportion of grass in the diet of cows increased CLA content, with the highest levels of unsaturated FA and the lowest levels of saturated FA, increasing the added value of milk on grazing systems using available farm resources.

    Communication is an essential aspect of life, yet it can be taken for granted. Its centrality to being in the world and in professional practice often becomes evident when nurses and older adults encounter communication difficulties. The factors that can affect nurses' communication with older adults relate to the older adult, the nurse, sociocultural considerations and the environment, and the interactions between these factors. In adopting a person-centred approach to communicating with older adults, it is necessary to get to know the person as an individual and ensure communication meets their needs and abilities. Effective communication is essential in nursing practice and requires professional competence and engagement. This article can be used by nurses to support effective communication with older adults across the continuum of care.

    1991-01-01

    When people involved in the power industry think of Solar Magnetic Disturbances (SMD), they normally consider the potential for disrupting power transmission which results form solar-induced disturbances to the earth's magnetic field known as geomagnetic storms. However, in addition to the disruption of power transmission, solar phenomena can interfere with utility communication systems. Utilities use many different types of communication media, some of which can be affected by various solar phenomena. These include wire-based facilities (metallic cables and power line carrier), radio systems (HF, VHF, UHF mobile radio, microwave networks, and satellite transmissions), and fiber optic systems. This paper reports that the solar flares and other solar phenomena can affect these media through different mechanisms: Radio communications can be disturbed by flare-induced changes in the ionispheric layer of the atmosphere; Cable communications can be disrupted by the flare-induced changes in the magnetosphere which surrounds the earth. These changes, in turn, induce currents in the power equipment that energizes long communications cables; Satellite communications can be disrupted by the flare-induced perturbations of satellite orbits and equipment

    Effective communication in dairy farms improves management and herd health, and it is also pivotal for public health in a "from farm to fork" perspective. This paper reports the results of a descriptive study on dairy farmers' perception of veterinarian and other consultants' communication skills. Perceived communication skills showed to be significantly lower than desired ones for all the professional figures considered. Despite these unsatisfactory results, veterinarian were the most appreciated and skilled consultants. The observed farmers' dissatisfaction increases farmers' difficulties in identifying proper targets and proper consultant. An increase in the skill of veterinarian to deliver effective and tailored messages could help to overcome the problem. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Aim of study: To analyze the effect of health status on cork production, analyzing if this influence is uniform or is affected by site conditions.Area of study: Two Western Algerian cork tree forests have been studied: M’Sila located in the coastal plains under semiarid climate, and Zarieffet, located in the mountainous interior under sub-humid climate.Material and Methods: 40 trees were selected in each forest and classified according to their health status as healthy, weakened, or decaying. A sample of cork from each tree has been obtained to measure the key variables related to cork production. A two-way ANOVA was performed considering two factors: site and health status.Main results: Quercus suber L. productivity is affected by the vitality of trees in the same way in both sources, showing values between 5.96 ± 7.1 kg • m-2 (coast, weakened trees and 8.13 ± 0.45 kg • m-2 (mountain, healthy trees.

    2015-08-01

    The objective of this study was to compare the effect of 4 antiseptic compounds on the healing rate and incidence of infection of umbilical cords in newborn calves (n=60). Late gestation Jersey cows were monitored at a commercial farm (Sioux Jersey, Salix, IA) and newborn purebred (n=30) and crossbred (n=30) calves were obtained within 30min after birth. Calves were alternately assigned by birth order to 4 treatment groups: 7% tincture of iodine, 0.1% chlorine created using a novel chlorine disinfectant technology, chlorohexidine gluconate 4.0% wt/vol, and 10% trisodium citrate. Prior to dipping (within 30min of birth), diameter of the umbilical cords (as an indicator of cord drying and healing) were determined using digital calipers. In addition, as an indicator of umbilical infections, surface temperature of the umbilical stump (along with a reference point at the midpoint of the sternum) was determined using a dual-laser infrared thermometer. These measurements were all repeated at 24±1 h of age. All data were analyzed using mixed model methods. All models included fixed effects of breed (Jersey or Jersey cross), sex (bull or heifer), and treatment. Fixed effect interactions were not included in the statistical model due to the relatively small sample size. No treatment differences were noted for healing rate of umbilical cords. Initially, mean umbilical cord diameter was 22.84±3.89mm and cords healed to a mean diameter of 7.64±4.12mm at 24 h of age. No umbilical infections were noted for calves on any treatment during the course of this study. Mean surface temperature of the umbilical stump was 33.1±2.2°C at birth (1.5±1.6°C higher than the sternal reference temperature), and at 24±1 h of age the mean temperature of the umbilical stump was 33.0±4.3°C (0.5±1.8°C lower than the sternal reference temperature). These data suggest that these antiseptic compounds are equally effective for preventing infections and permitting healing of the umbilical cord

    To determine the effect of age at grouping on behavior, health, and production of dairy bull calves, 90 Holstein-Friesian bull calves were housed in individual pens until moved to 1 of 3 treatments. Calves were housed in groups of 3 calves at 3 d old (GH3), 7 d old (GH7), or 14 d old (GH14) until 7 wk of age. Ten groups of 3 calves for each treatment were used, with 5 pens/treatment in each of 2 replications (10 pens/treatment, 3 treatments, 3 calves/treatment; 90 calves total). Direct behavioral observations using instantaneous scan sampling every 10 min were conducted twice per week for 7 wk. At the same times, video data were recorded for continuous observations at feeding time to observe the overall activity of group-housed calves. Hip height, heart girth, and health scores were recorded weekly and body weight was recorded at the start and end of the study. Calves in GH3 spent more time playing and but more time cross-sucking and displacing other calves from milk bottles. Calves engaged in social interaction as early as 3 d of age, and social interactions between 3 to 6 wk of age increased markedly. Calves housed in GH14 vocalized more than did calves in GH7 and GH3. No difference was found between treatments in growth performance. Calf fecal, cough, and nasal and ocular discharge scores, differential leukocyte counts, and plasma cortisol concentrations were not affected by age at grouping. However, during the first week of grouping, when calves were moved from individual pens to group pens, some calves were unable to find their milk bottles and required guidance. In conclusion, these data show no adverse effects on health or performance and some benefits on social behavior for early (d 3) grouping of calves.

    Forty-four Holstein calves were fed a direct-fed microbial (DFM) and 1 of 2 milk replacers to evaluate calf performance and growth. Treatments were (1) a control milk replacer [22:20; 22% crude protein (CP) and 20% fat], (2) an accelerated milk replacer (27:10; 27% CP and 10% fat), (3) the control milk replacer with added DFM (22:20+D), and (4) the accelerated milk replacer with added DFM (27:10+D). Dry matter intake, rectal temperatures, respiration scores and rates, and fecal scores were collected daily. Body weight, hip and withers height, heart girth, blood, and rumen fluid samples were collected weekly. Effects of treatment, sex, week, and their interactions were analyzed. Calves fed an accelerated milk replacer, regardless of DFM supplementation, consumed more CP and metabolizable energy in the milk replacer. No treatment differences were found for starter intake or intake of neutral detergent fiber or acid detergent fiber in the starter. Calves fed the accelerated milk replacer had greater preweaning and weaning body weight compared with calves fed the control milk replacer. Average daily gain was greater during the preweaning period for calves fed the accelerated milk replacer, but the same pattern did not hold true during the postweaning period. Feed efficiency did not differ among treatments. Hip height tended to be and withers height and heart girth were greater at weaning for calves fed the accelerated milk replacer compared with calves fed the control milk replacer. Fecal scores were greatest in calves fed DFM. Overall acetate, propionate, butyrate, and n-valerate concentrations were lower in calves fed the accelerated milk replacer, but DFM did not have an effect. Rumen pH was not different. Blood metabolites were unaffected by DFM supplementation, but calves fed the accelerated milk replacer had increased partial pressure of CO2, bicarbonate, and total bicarbonate in the blood. Direct-fed microbial supplementation did not appear to benefit the calf

    Full Text Available Strategic application of moxidectin pour-on (Cydectin(R was evaluated in Uganda for its effect on pasture larval counts and gastrointestinal nematode faecal egg counts in village cattle kept under tethering (semi-intensive grazing management. The strategic deworming schedule involved treating cattle twice at an interval of 2 months, at the end of the 1st wet season and during the 2nd wet season. Two groups of 30 cattle, each consisting of a treated and a control group, were examined for nematode infections every 4 weeks from June 1999 to January 2000. The treated group had significantly lower mean faecal egg counts than the untreated groups (t-value = 2.47, P < 0.05. Generally, the pasture larval counts on treated farms were lower than on untreated ones, but not significantly so (t-value = 2.22, P = 0.068. Pasture larval counts with different nematode species on treated farms were lower than on untreated ones, but the differences were not significant for Haemonchus spp. (t-value=1.68, P=0.145, Oesophagostomum spp. (t-value= 1.87, P=0.111, Trichostrongylus spp. (t-value=1.93, P=0.102, Dictyocaulus spp. (t-value= -0.74, P=0.485 and Cooperia spp. (t-value=-1.00, P=0.356. Treated farms did , however, have significantly lower pasture larval counts of Bunostomum spp. (t-value=4.64, P<0.05. This study has revealed that the application ofmoxidectin pour-on on cattle has an effect on faecal egg count and pasture contamination under the tethering grazing system. Moxidectin pour-on and the strategic deworming schedule evaluated here could be used for the control of gastrointestinal nematode infections in cattle by small-scale farmers who practise tethering or semi-intensive grazing management in Uganda and other tropical countries, especially where there is a bimodal rainfall pattern.

    The effects of whey protein addition and transglutaminase treatment, alone and in combination, on the physical and sensory properties of reduced-fat ice cream were investigated. Adding whey protein with or without enzyme treatment decreased melting rate, overrun, and hardness of the reduced-fat ice cream; however, the enzyme-treated sample had a higher melting rate and overrun and softer texture. Whey protein-fortified samples showed higher melting resistance, but lower overrun and firmer texture compared with the enzyme-treated sample without added whey protein. Whey protein addition with or without transglutaminase treatment caused an increase in apparent viscosity and a decrease in flow index of the reduced-fat ice cream; nevertheless, the flow behavior of full-fat sample was most similar to the enzyme-treated reduced-fat sample with no added whey protein. Descriptive sensory analyses showed that neither whey protein addition nor transglutaminase treatment significantly influenced the flavor and odor of reduced-fat ice cream, but they both noticeably improved the color and texture of the final product. The results of this study suggest that whey protein addition with transglutaminase treatment improves the physical and sensory properties of reduced-fat ice cream more favorably than does whey protein addition or transglutaminase treatment alone.

    Full Text Available Plant growth promoting rhizobacteria (PGPR containing ACC-deaminase in combination with rhizobia can improve the growth and nodulation in plants by suppressing the endogenous level of ethylene. In the present study, ten strains, each of PGPR and rhizobia from the previously screened cultures were tested for their effect as co-inoculants on growth and nodulation of lentil in growth pouches under axenic conditions. Results showed that most of the combinations improved the lentil growth as compared to the un-inoculated control. Maximum increase in shoot length (1.87 fold, root length (1.97 fold and total biomass (1.98 fold over the un-inoculated control was observed in the treatment where the lentil seedlings were inoculated with the combination Z24P10. Co-inoculation also improved the nodulation in lentil and the maximum number of nodules plant-1 (24 nodules were observed in the combination Z22P10. However, there was no nodulation in few combinations. It is concluded that the co-inoculation with rhizobia and PGPR containing ACC-deaminase has improved the growth and nodulation in lentil under axenic conditions and the selected combinations may be evaluated in pot and field trials

    To evaluate and compare shear bond strengths of composite resins to primary enamel and dentine when the adhesives are pre-cured (light cured before the application of the resin) or co-cured (adhesive and the resin light cured together). Buccal surfaces of 80 caries-free primary molars were wet ground to create bonding surfaces on enamel and dentine and specimens mounted on acrylic blocks. Two bonding agents (Prime and Bond NT® and Xeno III®) were applied to either enamel or dentine as per manufacturer's instructions. In 40 specimens, the bonding agent was light cured immediately after the application (pre-cured). The other 40 specimens were not light cured until the composite resin application (co-cured). Resin composite cylinders were made incrementally using acrylic moulds over the adhesives and light cured. Specimens were stored in deionised water for 24 hours at room temperature. Shear bond strength was measured using an Instron universal testing machine (in MPa) and was analysed with Student's unpaired t test. Light curing the adhesive separately produced significantly higher bond strengths to primary dentine than co-curing (padhesive separately did not produce significantly different bond strengths to primary enamel (p>0.05). Curing sequence had no significant effect on shear bond strength of adhesives on the primary enamel. Pre-curing adhesives before curing composite resins produced greater shear bond strength to primary dentine.

    The aim of this study was to determine the effect of canola meal use as a protein source in a starter mixture (SM) on feeding behavior and performance of calves during weaning transition. A total of 36 female Holstein calves of a mean age 14.9±1.6 d and body weight 40.1±4.2 kg (mean ± SD) were allocated to 1 of 3 treatments differing in the main source of protein for the SM (12 calves per treatment): (1) soybean meal (TSBM); (2) soybean meal and canola meal (TSBM/TCM); and (3) canola meal (TCM). The SM was offered for ad libitum consumption beginning on the first day of the study, whereas milk replacer (MR) was fed in amounts equal to 900 g (as fed) per day from d 1 to 35 and 450 g/d from d 36 to 42 of the study. Calves were completely weaned on d 43 of the study (57.9±1.6 d of age; mean ± SD), and their performance was monitored for an additional 2 wk. Calf body weight was recorded weekly, and MR and SM intake and fecal fluidity were recorded daily. Feeding behavior of calves during weaning transition, including frequency (no./d), time (min/d), and rate (g/min) of eating the SM as well as frequency and time of drinking water, was monitored on 6 calves per treatment for 2 consecutive days before MR step-down (d 34-35), at MR step-down (d 41-42), and after weaning (d 48-49 of study). Starter mixture intake tended to be higher for TSBM calves as compared with TSBM/TCM calves from d 1 to 35 of the study but was not different between TSBM and TCM calves and was not different between treatments in the whole study period. Calves from TCM treatment had reduced average daily gain (ADG) and feed efficiency (g of ADG/kg of dry matter intake) and a higher fecal score in the period from d 1 to 35 of the study and had lower feed efficiency and tended to have lower ADG in the whole study period as compared with TSBM calves. Average daily gain and feed efficiency did not differ between TSBM and TSBM/TCM calves. Frequency of eating the SM and drinking water as well as time

    Full Text Available Aflatoxin B1 (AFB1 is the most toxic form among the mycotoxins. Cytokines are important mediators of the immune system. T-cell subsets play a crucial role in cell-mediated immunity. The aim of present study was to evaluate the effects of dietary AFB1 on the cytokines expression and T-cell subsets in the cecal tonsil of broiler chickens throughout a 21-day experimental period. One hundred and fifty six one-day-old broiler chickens were randomly divided into control group (0 mg AFB1/kg feed and AFB1 group (0.6 mg pure AFB1/kg feed. At 7, 14 and 21 days of age, the levels of seven cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, IFN-γ and TNF-α mRNA expression as well as the proportions of T-cell subsets (CD3+, CD3+CD4+, CD3+CD8+ by qRT-PCR and flow cytometry methods were assessed in the cecal tonsils. The levels of the seven cytokines mRNA expression and the percentages of T-cell subsets significantly decreased at 14 and 21 days of age in the AFB1 group compared with the control group. However, the CD4+/CD8+ ratio was not significantly changed. These results demonstrate that 0.6 mg/kg AFB1 dietary exposure reduced the levels of cytokines mRNA expression and the percentages of T-cell subsets in the cecal tonsils of broiler chickens, suggesting that the cell-mediated immunity of cecal tonsils might be impaired in broilers.

    Full Text Available Peliosis hepatis is a rare liver disease characterized by blood-filled cavities scattered irregularly throughout the liver. Risk factors for peliosis include chronic illness such as AIDS, tuberculosis, cancer also use of some drugs such as anabolic steroids and azathioprine. The aim of the present study was to evaluate the curative properties of crocus sativus petals on induced peliosis hepatis in rats. Thirty two male Wistar rats (weight: 180-220 g were randomly divided into four equal groups: group 1 (healthy group received only IP normal saline, group2 received IP 80mg/kg.bw gentamicin, group3 IP 80mg/kg.bw gentamicin+ 40mg/kg crocus sativus petal extract, and group 4 was given IP 80mg/kg.bw gentamicin+ 40mg/kg crocus sativus petal extract. At the end of the experiment, the rats were anesthetized and their blood samples were collected through cardiac puncture for AST and ALT measurement.Then, the livers of the subjects were excised and fixed in formalin. It was found that AST significantly increased in gentamicin group (P<0.05 compared to the healthy group and groups treated by means of crocus sativus petal extract .Moreover, there was no significant differences between the groups administered the extract and those given gentamicin. Histologically,heterogeneous multiple blood-filled cavities were observed in gentamicin group (2 and the treatment groups (3 and 4. The results of the present study show that doses of hydroalcoholic extract of crocus sativus do not effect on peliosis hepatic and telangiectasis due to gentamicin sulfate in rats

    Full Text Available Nutritional disorders like ruminal acidosis are common in Spanish beef production system, in which animals are fed diets with a high content in starch. This experiment studied the effect of feed presentation form (concentrate and straw offered separately, CD, or mixed in form of briquettes, BR on the pattern of intake, growth and rumen pH of beef cattle fed high concentrate diets. The experiment was performed with 40 Holstein male calves, 32 of them for determining feed intake pattern and productive rates, and the remaining 8, which were previously provided with a ruminal cannula, to monitor rumen pH in two 21-day consecutive periods following a change-over design. Animals fed BR reduced feed intake rate during the first hour after feeding (18.6 vs. 24.0% of daily intake p<0.001, but this diet promoted a lower rumen pH at all sampling times compared with CD (daily average of 5.98 vs. 6.33; p<0.001 and tended to promote a lower total feed intake (7.08 vs. 9.77 kg DM/d; p<0.001 and daily weight gain (1.43 vs. 1.76 kg/d; p=0.056. Offering the concentrate and the straw mixed in form of briquettes is not useful to prevent ruminal acidosis and improve growth, probably due to both a reduced particle size of straw and avoided self-regulation of straw intake along the day.

    Full Text Available Vehicular communication is a widely researched field and aims at developing technologies that may complement systems such as the advanced driver assistance systems. It is therefore important to analyse and infer on the performance of vehicular technologies for different driving and on-road criteria. This study considers the dedicated short range communications technology and more precisely the IEEE 802.11p standard for a performance and practicability analysis. There is also the proposal of a new classification scheme for typical driving conditions, which includes the main categories of Emergency and Safety scenarios while sub-classifications of Critical and Preventive Safety also exist. The scheme is used to build up scenarios as well as related equations relevant to developing countries for practical network simulation. The results obtained indicate that the relative speed of nodes is a determining factor in the overall performance and effectiveness of wireless vehicular communication systems. Moreover, delay values of low order were observed while an effective communication range of about 800 m was calculated for highway scenarios. The research thus indicates suitability of the system for an active use in collision avoidance even though independent factors such as climatic conditions and driver behaviour may affect its effectiveness in critical situations.

    A new spontaneous phenotype of the rice cultivar L-202 was found. Mendelian analysis indicates that it is a monogenic, recessive mutant. Its distinguishing features are: dark blue-green colour, short and narrow leaves, high tillering and relatively short height. The objectives of this study were: to characterize it, to determine if it is heritable and if so, its genetic basis. Its distinguishing features are: dark blue-green colour, short and narrow leaves, high tillering and relatively short height. Selfing the new phenotype resulted in a uniform progeny, with the traits of the parent plant (wild type). Crossing the new phenotype with the normal L-202 cultivar resulted in a uniform F1 hybrid generation, with the wild type. The F2 generation showed a mendelian segregation which did not depart significantly from three normal plants : one new phenotype. It is concluded that it is a monogenic, recessive mutant.

    2012-09-01

    The purpose of this study was to develop a practical mean for clinical evaluation of early pediatric language development by establishing developmental trajectories for receptive and expressive vocabulary growth in children between 6 and 32 months of age using a simple, time-efficient assessment tool. Simplified short form versions of the Words and Gestures and Words and Sentences vocabulary inventories in the Mandarin Communicative Development Inventory [1] were developed and used to assess early language development in developmentally normal children from 6 to 32 months of age during routine health checks. Developmental trajectories characterizing the rate of receptive and expressive vocabulary growth between 6 and 32 months of age are reported. These trajectories allow the equivalent age corresponding to a score to be determined after a brief structured interview with the child's parents that can be conducted in a busy clinical setting. The simplified short forms of the Mandarin Communicative Development Inventories can serve as a clinically useful tool to assess early child language development, providing a practical mean of objectively assessing early language development following early interventions to treat young children with hearing impairment as well as speech and language delays. Objective evidence of language development is essential for achievement of effective (re)habilitation outcomes. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    A strong interest and need exist in the workplace today to master the skills of conducting difficult conversations. Theories and strategies abound, yet none seem to have found the magic formula with universal appeal and success. If it is such an uncomfortable skill to master is it better to avoid or initiate such conversations with employees? Best practices and evidence-based management guide us to the decision that quality improvement dictates effective communication, even when difficult. This brief paper will offer some suggestions for strategies to manage difficult conversations with employees. Mastering the skills of conducting difficult conversations is clearly important to keeping lines of communication open and productive. Successful communication skills may actually help to avert confrontation through employee engagement, commitment and appropriate corresponding behavior

  19. Effects of noise and task loading on a communication task loading on a communication task

    Science.gov (United States)

    Orrell, Dean H., II

    Previous research had shown the effect of noise on a single communication task. This research has been criticized as not being representative of a real world situation since subjects allocated all of their attention to only one task. In the present study, the effect of adding a loading task to a standard noise-communication paradigm was investigated. Subjects performed both a communication task (Modified Rhyme Test; House et al. 1965) and a short term memory task (Sternberg, 1969) in simulated levels of aircraft noise (95, 105 and 115 dB overall sound pressure level (OASPL)). Task loading was varied with Sternberg's task by requiring subjects to memorize one, four, or six alphanumeric characters. Simulated aircraft noise was varied between levels of 95, 105 and 115 dB OASPL using a pink noise source. Results show that the addition of Sternberg's task and little effect on the intelligibility of the communication task while response time for the communication task increased.

  1. Space weather effects on communications

    Science.gov (United States)

    Lanzerotti, Louis J.

    In the 150 years since the advent of the first electrical communication system - the electrical telegraph - the diversity of communications technologies that are embedded within space-affected environments have vastly increased. The increasing sophistication of these communications technologies, and how their installation and operations may relate to the environments in which they are embedded, requires ever more sophisticated understanding of natural physical phenomena. At the same time, the business environment for most present-day communications technologies that are affected by space phenomena is very dynamic. The commercial and national security deployment and use of these technologies do not wait for optimum knowledge of possible environmental effects to be acquired before new technological embodiments are created, implemented, and marketed. Indeed, those companies that might foolishly seek perfectionist understanding of natural effects can be left behind by the marketplace. A well-considered balance is needed between seeking ever deeper understanding of physical phenomena and implementing `engineering' solutions to current crises. The research community must try to understand, and operate in, this dynamic environment.

    2017-10-01

    Science communication is becoming ever more prevalent, with more and more scientists expected to not only communicate their research to a wider public, but to do so in an innovative and engaging manner. Given the other commitments that researchers and academics are required to fulfil as part of their workload models, it is unfair to be expect them to also instantly produce effective science communication events and activities. However, by thinking carefully about what it is that needs to be communicated, and why this is being done, it is possible to develop high-quality activities that are of benefit to both the audience and the communicator(s). In this paper, I present some practical advice for developing, delivering and evaluating effective science communication initiatives, based on over a decade of experience as being a professional science communicator. I provide advice regarding event logistics, suggestions on how to successfully market and advertise your science communication initiatives, and recommendations for establishing effective branding and legacy.

    2010-08-01

    Effective Communication Skills form part of what is being a good doctor. There is a solid evidence base that defines the components of effective communication. This article offers a practical conceptual framework to improve physician patient communication to a professional level of competence. There are six goals that physicians and patients work to achieve through their communication with each other. These are to construct a relationship, structure an interview, start the interview, gather information, explain, plan and close the interview. The outcomes that can be improved with an effective communication and the "first principles" of communication are described. A brief look at the historical context that has influenced our thinking about communication in health care is carried out. Finally, the Calgary Cambridge Guide, an approach for delineating and organizing the specific skills required of an effective communication with patients is described. It is clear from the literature that better communication skills improve patient satisfaction and clinical outcomes.

  14. Short communication: Biochemically active humic substances in contrasting agricultural managements

    Full Text Available Because their crucial role in several soil biochemical cycles and their fast response to changes in soil management, extracellular enzymes activities are widely used as sensitive indicators of ecological change and soil quality. The aim of this work was to determine the effects of soil management on the stable pool of soil carbon cycling enzymes as indicators of essential functions. For this, extracellular β-glucosidase enzymes bounded by humic acids (C higher than 104 Da were used to compare four long-term contrasting agricultural managements in a rainfed olive orchard representative of semi-arid Mediterranean habitats. The study was conducted for 30 years by designing a random-block of four treatments (nude vs. covered soils and four replicates. Maintaining cover crops through fall, winter and early spring provoked a more stable and active pool of extracellular β-glucosidase in soils only if spontaneous vegetation was managed with mechanical methods. When herbicides were used during 30 years, the pattern of the molecular composition and activity of humus β-glucosidase complexes were similar in covered and nude soils, although higher activity was retrieved in the former. Tillage management increased carbon mineralization and the level of humic substances and the activity of β-glucosidase humic-bound were quite lower than in the rest of treatments.

    Lactose is an energy source for culture bacteria. Bile tolerance is an important probiotic property. Our aim was to elucidate the effect of lactose on bile tolerance of yogurt starter culture Lactobacillus bulgaricus LB-12 and Streptococcus thermophilus ST-M5. Bile tolerance of pure cultures was determined using 0.3% oxgall in MRS THIO broth (Difco, Becton Dickinson, Sparks, MD) for L. bulgaricus and 0.3% oxgall in M17 broth (Oxoid, Basingstoke, UK) for Strep. thermophilus. Lactose was added to both broths at 0 (control), 1, 3, and 5% (wt/vol) broth. Dilutions were plated hourly for 12 h. Experiments were replicated 3 times. At 2, 4, and 12 h of incubation, lactose incorporated at all amounts, 1, 3, and 5% (wt/vol), showed higher counts of Strep. thermophilus ST-M5 compared with the control. Lactose use at 5% (wt/vol) significantly enhanced bile tolerance of both L. bulgaricus and Strep. thermophilus compared with control. Copyright © 2018 American Dairy Science Association.

  16. Short communication: Biochemically active humic substances in contrasting agricultural managements

    Because their crucial role in several soil biochemical cycles and their fast response to changes in soil management, extracellular enzymes activities are widely used as sensitive indicators of ecological change and soil quality. The aim of this work was to determine the effects of soil management on the stable pool of soil carbon cycling enzymes as indicators of essential functions. For this, extracellular β-glucosidase enzymes bounded by humic acids (C higher than 104 Da) were used to compare four long-term contrasting agricultural managements in a rainfed olive orchard representative of semi-arid Mediterranean habitats. The study was conducted for 30 years by designing a random-block of four treatments (nude vs. covered soils) and four replicates. Maintaining cover crops through fall, winter and early spring provoked a more stable and active pool of extracellular β-glucosidase in soils only if spontaneous vegetation was managed with mechanical methods. When herbicides were used during 30 years, the pattern of the molecular composition and activity of humus β-glucosidase complexes were similar in covered and nude soils, although higher activity was retrieved in the former. Tillage management increased carbon mineralization and the level of humic substances and the activity of β-glucosidase humic-bound were quite lower than in the rest of treatments. Given the ecological role of extracellular soil carbon cycling enzymes, the characterization of humus β-glucosidase complexes could be an adequate indicator of sustainability of agricultural management systems.

  17. CONSIDERATIONS REGARDING THE EFFECTS OF LEGAL COMMUNICATION

    Directory of Open Access Journals (Sweden)

    Claudiu Ramon D. Butculescu

    2015-11-01

    Full Text Available This article addresses some aspects of legal communication or legal effects of communication. As such, legal communication can have positive and negative effects. Both effects are briefly analyzed, and for the negative effects of legal communication we have also presented proposals to reduce the negative effects of law communication. Thus, the article presents the positive effects of right communication in various branches of law such as civil, constitutional law or tax law. On the other hand, the negative effects of communication leading to the deterioration of the legal message, so that much of the legal message becomes legal noise. Another negative effect of miscommunication of law is the phenomenon of legislative inflation, which has a profound impact on the way in which legal rules are understood and respected by community members. All these negative effects produce serious consequencesin civil law, company law, tax law, and in many other areas of law.

  18. Phonological awareness and short-term memory in hearing and deaf individuals of different communication backgrounds.

    Previous work in deaf populations on phonological coding and working memory, two skills thought to play an important role in the acquisition of written language skills, have focused primarily on signers or did not clearly identify the subjects' native language and communication mode. In the present study, we examined the effect of sensory experience, early language experience, and communication mode on the phonological awareness skills and serial recall of linguistic items in deaf and hearing individuals of different communicative and linguistic backgrounds: hearing nonsigning controls, hearing users of ASL, deaf users of ASL, deaf oral users of English, and deaf users of cued speech. Since many current measures of phonological awareness skills are inappropriate for deaf populations on account of the verbal demands in the stimuli or response, we devised a nonverbal phonological measure that addresses this limitation. The Phoneme Detection Test revealed that deaf cuers and oral users, but not deaf signers, performed as well as their hearing peers when detecting phonemes not transparent in the orthography. The second focus of the study examined short-term memory skills and found that in response to the traditional digit span as well as an experimental visual version, digit-span performance was similar across the three deaf groups, yet deaf subjects' retrieval was lower than that of hearing subjects. Our results support the claim (Bavelier et al., 2006) that lexical items processed in the visual-spatial modality are not as well retained as information processed in the auditory channel. Together these findings show that the relationship between working memory, phonological coding, and reading may not be as tightly interwoven in deaf students as would have been predicted from work conducted in hearing students.

  1. Multimedia Astronomy Communication: Effectively Communicate Astronomy to the Desired Audience

    Science.gov (United States)

    Star Cartier, Kimberly Michelle; Wright, Jason

    2017-01-01

    A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

    Knowledge of contraceptive effectiveness is crucial to making an informed choice. The consumer has to comprehend the pros and cons of the contraceptive methods being considered. Choice may be influenced by understanding the likelihood of pregnancy with each method and factors that influence effectiveness. To review all randomized controlled trials comparing strategies for communicating to consumers the effectiveness of contraceptives in preventing pregnancy. Through February 2013, we searched the computerized databases of MEDLINE, POPLINE, CENTRAL, PsycINFO and CINAHL, ClinicalTrials.gov, and ICTRP. Previous searches also included EMBASE. We also examined references lists of relevant articles. For the initial review, we wrote to known investigators for information about other published or unpublished trials. We included randomized controlled trials that compared methods for communicating contraceptive effectiveness to consumers. The comparison could be usual practice or an alternative to the experimental intervention.Outcome measures were knowledge of contraceptive effectiveness, attitude about contraception or toward any particular contraceptive, and choice or use of contraceptive method. For the initial review, two authors independently extracted the data. One author entered the data into RevMan, and a second author verified accuracy. For the update, an author and a research associate extracted, entered, and checked the data.For dichotomous variables, we calculated the Mantel-Haenszel odds ratio with 95% confidence intervals (CI). For continuous variables, we computed the mean difference (MD) with 95% CI. Seven trials met the inclusion criteria and had a total of 4526 women. Five were multi-site studies. Four trials were conducted in the USA, while Nigeria and Zambia were represented by one study each, and one trial was done in both Jamaica and India.Two trials provided multiple sessions for participants. In one study that examined contraceptive choice, women in

  18. Flexible multimode polymer waveguides for high-speed short-reach communication links

    Multimode polymer waveguides have attracted great interest for use in high-speed short-reach communication links as they can be cost-effectively integrated onto standard PCBs using conventional methods of the electronics industry and provide low loss (30 GHz×m) interconnection. The formation of such waveguides on flexible substrates can further provide flexible low-weight low-thickness interconnects and offer additional freedom in the implementation of high-speed short-reach optical links. These attributes make these flexible waveguides particularly attractive for use in low-cost detachable chip-to-chip links and in environments where weight and shape conformity become important, such as in cars and aircraft. However, the highly-multimoded nature of these waveguides raises important questions about their performance under severe flex due to mode loss and mode coupling. In this work therefore, we investigate the loss, crosstalk and bandwidth performance of such waveguides under out-of plane bending and in-plane twisting under different launch conditions and carry out data transmission tests at 40 Gb/s on a 1 m long spiral flexible waveguide under flexure. Excellent optical transmission characteristics are obtained while robust loss, crosstalk and bandwidth performance are demonstrated under flexure. Error-free (BER<10-12) 40 Gb/s data transmission is achieved over the 1 m long spiral waveguide for a 180° bend with a 4 mm radius. The obtained results demonstrate the excellent optical and mechanical properties of this technology and highlight its potential for use in real-world systems.

    Yamamoto, Naokatsu; Akahane, Kouichi; Umezawa, Toshimasa; Kawanishi, Tetsuya

    2015-04-01

    A monolithically integrated quantum dot (QD) optical gain modulator (OGM) with a QD semiconductor optical amplifier (SOA) was successfully developed. Broadband QD optical gain material was used to achieve Gbps-order high-speed optical data transmission, and an optical gain change as high as approximately 6-7 dB was obtained with a low OGM voltage of 2.0 V. Loss of optical power due to insertion of the device was also effectively compensated for by the SOA section. Furthermore, it was confirmed that the QD-OGM/SOA device helped achieve 6.0-Gbps error-free optical data transmission over a 2.0-km-long photonic crystal fiber. We also successfully demonstrated generation of Gbps-order, high-speed, and error-free optical signals in the >5.5-THz broadband optical frequency bandwidth larger than the C-band. These results suggest that the developed monolithically integrated QD-OGM/SOA device will be an advantageous and compact means of increasing the usable optical frequency channels for short-reach communications.

    The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication. © 2014 by the Society for Personality and Social Psychology, Inc.

    Светлана Валентиновна Ионова

    2015-12-01

    Full Text Available The article discusses the problem of emotional significance of a positive form of speech. Based on the methodology of emotions linguistics, linguoecology, communicative linguistics and the methods of description, comparison and discourse analysis, the author distinguishes some types of speech situations that demonstrate visible differences between positive expression of emotions and their content and the pragmatic effect. The difference between the notions of “positive communication” and “positive form of communication” is demonstrated. Special attention is given to the following types of positive emotional communication: tolerant emotional communication, emotional emphasis, emotional neglect, and emotional tabooing. The utterances in situations of real and textual communication demonstrate negative effects of statements expressed in a positive form and identify the specifics of positive forms of emotional communication in comparison with rational communication.

    2010-01-01

    Full Text Available We discuss how a short-range wireless communication service implemented for modern mobile communication devices can provide additional value for both the consumer and the service/product provider. When used as an information search tool, such systems allow services and products being promoted at the location they are available. For the customer, it may provide a “digitally augmented vision”, an enhanced view to the current environment. With data filtering and search rules, this may provide a self-manageable context, where the user's own personal environment and preferences to the features available in the current surroundings cooperate with a direct connection to the web-based social media. A preliminary design for such service is provided. The conclusion is that the method can generate additional revenue to the company and please the customers' buying process. In addition to the marketing, the principles described here are also applicable to other forms of human interaction.

  9. Neural processing of short-term recurrence in songbird vocal communication.

    Directory of Open Access Journals (Sweden)

    Gabriël J L Beckers

    Full Text Available BACKGROUND: Many situations involving animal communication are dominated by recurring, stereotyped signals. How do receivers optimally distinguish between frequently recurring signals and novel ones? Cortical auditory systems are known to be pre-attentively sensitive to short-term delivery statistics of artificial stimuli, but it is unknown if this phenomenon extends to the level of behaviorally relevant delivery patterns, such as those used during communication. METHODOLOGY/PRINCIPAL FINDINGS: We recorded and analyzed complete auditory scenes of spontaneously communicating zebra finch (Taeniopygia guttata pairs over a week-long period, and show that they can produce tens of thousands of short-range contact calls per day. Individual calls recur at time scales (median interval 1.5 s matching those at which mammalian sensory systems are sensitive to recent stimulus history. Next, we presented to anesthetized birds sequences of frequently recurring calls interspersed with rare ones, and recorded, in parallel, action and local field potential responses in the medio-caudal auditory forebrain at 32 unique sites. Variation in call recurrence rate over natural ranges leads to widespread and significant modulation in strength of neural responses. Such modulation is highly call-specific in secondary auditory areas, but not in the main thalamo-recipient, primary auditory area. CONCLUSIONS/SIGNIFICANCE: Our results support the hypothesis that pre-attentive neural sensitivity to short-term stimulus recurrence is involved in the analysis of auditory scenes at the level of delivery patterns of meaningful sounds. This may enable birds to efficiently and automatically distinguish frequently recurring vocalizations from other events in their auditory scene.

    2014-01-01

    Full Text Available This paper deals with the value or more specifically, the contribution of marketing communications strategy to effectiveness of marketing communications and hypothesizes that marketing communications strategy correlate with the effectiveness of marketing communications. The paper consists of two parts: the theoretical framework for the role of marketing communications strategy for the effectiveness of the marketing communications and the empirical analysis, based on the primary data collected. The concept of the marketing communication effectiveness assumes that there are variables that can have a positive influence on the effectiveness of marketing communications, which incorporates facets of the marketing communication strategy and bidirectional communications. The results suggest that Slovenian organisations which design and implement marketing communication strategy, also have more effective marketing communications. The development of marketing communications strategy was correlated with increased effectiveness of marketing communications in their organisation. Managerial implications are discussed along with directions for further research.

  18. Increasing pandemic vaccination rates with effective communication.

    Science.gov (United States)

    Henrich, Natalie J

    2011-06-01

    Communicating effectively with the public about the importance of vaccination during a pandemic poses a challenge to health communicators. The public's concerns about the safety, effectiveness and necessity of vaccines lead many people to refuse vaccination and the current communication strategies are often unsuccessful at overcoming the public's resistance to vaccinate. Convincing the public to receive a vaccination, especially during a pandemic when there can be so much uncertainty about the vaccine and the disease, requires a revised communication approach. This revised approach should integrate into messages information that the public identifies as important, as well as presenting messages in a way that is consistent with our evolved social learning biases. These biases will impact both the content of the message and who delivers the message to different target populations. Additionally, an improved understanding between media and health communicators about the role each plays during a crisis may increase the effectiveness of messages disseminated to the public. Lastly, given that the public is increasingly seeking health information from on-line and other electronic sources, health communication needs to continue to find ways to integrate new technologies into communication strategies.

    Chiniara, Lyne; Perry, Rebecca J; Van Vliet, Guy; Huot, Céline; Deal, Cheri

    2013-12-01

    In 2001, a chart review of children referred to the authors' endocrine clinic because of short stature revealed that many were referred with insufficient baseline data, had normal height velocity and were within genetic target height. Therefore, a two-way fax communication system was implemented between referring physicians and the authors' service before the first visit. Aspects that were assessed included whether this system increased the information accompanying the patient at referral, resulted in children with nonpathological shortness not being seen in the clinic, and was used differently by paediatricians and general practitioners. Between January and December 2006, 138 referrals for short stature, diagnosed with familial short stature, constitutional delay or idiopathic short stature, were audited (69 with and 69 without previous fax communication). Data collected included source of referral, clinical information provided, available growth measurements, and results from laboratory and imaging studies. Fax communication resulted in growth curves being provided more often (95.6% of cases versus 40.5% of cases without fax communication [Pshort stature being given to 31 children based on the growth curve, laboratory and imaging results, without the children being seen in the endocrine clinic. Fax communication was also used more frequently by paediatricians (84%) than by general practitioners (15%). The fax communication system resulted in a more complete evaluation of referred patients by their physicians and reduced the number of unnecessary visits to the authors' specialty clinic while promoting medical education.

    Smith, Karen

    2014-08-01

    Effective communication requires direct interaction between the hospitalist and the primary care provider using a standardized method of information exchange with the opportunity to ask questions and assign accountability for follow-up roles. The discharge summary is part of the process but does not provide the important aspects of handoff, such as closed loop communication and role assignments. Hospital discharge is a significant safety risk for patients, with more than half of discharged patients experiencing at least one error. Hospitalist and primary care providers need to collaborate to develop a standardized system to communicate about shared patients that meets handoff requirements. Copyright © 2014 Elsevier Inc.

What differs across diverse personalities is the level of communication effectiveness which ascertains the success in the flow of messages not only at the organizational level but also in the classroom where learning takes place. This study, which aimed to disclose correlations between language constructs and communication effectiveness, puts the light to the randomly selected educational management students of a state university in Cagayan Valley. Using a language test and a questionnaire, it was revealed that the level of language proficiency of the respondents as to correct usage, presentation and writing is very satisfactory, and as to subject-verb agreement, vocabulary, reading comprehension, listening comprehension, and action research, satisfactory; while their level of communication effectiveness along using non-verbal language, transmitting messages and receiving messages is high. At 0.05 level analysis, significant correlations exist between communication effectiveness (along using nonverbal language and receiving messages and language proficiency along reading. These findings provided insights in enhancing communication in classroom management, organizational management as well as in communication management instruction..

  6. Resonant communicators, effective communicators. Communicator’s flow and credibility

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Communication studies have been integrating the latest developments in cognitive sciences and acknowledging the importance of understanding the subjective processes involved in communication. This article argues that communication studies should also take into account the psychology of the communicator. This article presents the theoretical basis and the results of a training programme designed for audiovisual communicators. The programme is based on the theories of self-efficacy and flow and seeks to improve students’ communication competencies through the use of presentation techniques and psychological skills to tackle communication apprehension. The programme involves an active methodology that is based on modelling, visualisation, immediate feedback and positive reinforcement. A repeated-measures ANOVA shows that the programme successfully decreases the level of communication apprehension, improves the perceived self-efficacy, improves the psychological state needed to perform better in front of the cameras (flow, and improves students’ communication skills. A path analysis proved that the perceived self-efficacy and anxiety levels predict the level of flow during the communication act. At the end of the training programme, those who experienced higher levels of flow and enjoyment during the communication task achieved higher quality levels in their communication exercise. It is concluded that the concepts of self-efficacy and flow facilitate advancing in the understanding of the factors that determine a communicator’s credibility and ability to connect with the audience.

    Intuition from our everyday lives gives rise to the belief that information exchanged between remote parties is carried by physical particles. Surprisingly, in a recent theoretical study [Salih H, Li ZH, Al-Amri M, Zubairy MS (2013) Phys Rev Lett 110:170502], quantum mechanics was found to allow for communication, even without the actual transmission of physical particles. From the viewpoint of communication, this mystery stems from a (nonintuitive) fundamental concept in quantum mechanics—wave-particle duality. All particles can be described fully by wave functions. To determine whether light appears in a channel, one refers to the amplitude of its wave function. However, in counterfactual communication, information is carried by the phase part of the wave function. Using a single-photon source, we experimentally demonstrate the counterfactual communication and successfully transfer a monochrome bitmap from one location to another by using a nested version of the quantum Zeno effect.

  8. High-precision GNSS ocean positioning with BeiDou short-message communication

    2018-04-01

    The current popular GNSS RTK technique would be not applicable on ocean due to the limited communication access for transmitting differential corrections. A new technique is proposed for high-precision ocean RTK, referred to as ORTK, where the corrections are transmitted by employing the function of BeiDou satellite short-message communication (SMC). To overcome the limitation of narrow bandwidth of BeiDou SMC, a new strategy of simplifying and encoding corrections is proposed instead of standard differential corrections, which reduces the single-epoch corrections from more than 1000 to less than 300 bytes. To solve the problems of correction delays, cycle slips, blunders and abnormal epochs over ultra-long baseline ORTK, a series of powerful algorithms were designed at the user-end software for achieving the stable and precise kinematic solutions on far ocean applications. The results from two long baselines of 240 and 420 km and real ocean experiments reveal that the kinematic solutions with horizontal accuracy of 5 cm and vertical accuracy of better than 15 cm are achievable by convergence time of 3-10 min. Compared to commercial ocean PPP with satellite telecommunication, ORTK is of much cheaper expense, higher accuracy and shorter convergence. It will be very prospective in many location-based ocean services.

    A liquid crystal on silicon (LCoS) based polarization modulated image (PMI) system architecture using red-, green- and blue-based light-emitting diodes (LEDs), which offers simultaneous micro-projection and high-speed data transmission at nearly a gigabit, serving as an alternative short-range communication (SRC) approach for personal communication device (PCD) application in 5G, is proposed and experimentally demonstrated. In order to make the proposed system architecture transparent to the future possible wireless data modulation format, baseband modulation schemes such as multilevel pulse amplitude modulation (M-PAM), M-ary phase shift keying modulation (M-PSK) and M-ary quadrature amplitude modulation (M-QAM) which can be further employed by more advanced multicarrier modulation schemes (such as DMT, OFDM and CAP) were used to investigate the highest possible data transmission rate of the proposed system architecture. The results demonstrated that an aggregative data transmission rate of 892 Mb/s and 900 Mb/s at a BER of 10^(-3) can be achieved by using 16-QAM baseband modulation scheme when data transmission were performed with and without micro-projection simultaneously.

    Enhancing communication as a means of promoting relationship quality has been increasingly questioned, particularly for couples at elevated sociodemographic risk. In response, the current study investigated communication change as a mechanism accounting for changes in relationship satisfaction and confidence among 344 rural, predominantly low-income African American couples with an early adolescent child who participated in a randomized controlled trial of the Protecting Strong African American Families (ProSAAF) program. Approximately 9 months after baseline assessment, intent-to-treat analyses indicated ProSAAF couples demonstrated improved communication, satisfaction, and confidence compared with couples in the control condition. Improvements in communication mediated ProSAAF effects on relationship satisfaction and confidence; conversely, neither satisfaction nor confidence mediated intervention effects on changes in communication. These results underscore the short-term efficacy of a communication-focused, culturally sensitive prevention program and suggest that communication is a possible mechanism of change in relationship quality among low-income African American couples.

  1. Effective Climate Communication with Difficult Audiences

    Denning, S.

    2015-12-01

    Climate communication is often fraught with ideological baggage ("noise") that makes it very difficult to connect to audiences. In these cases, it is helpful to use "best practices" known from other fields of communication. Engaging audiences with authenticity, using plain language, respecting cultural and political differences, and a sprinkling of humor can go a long way toward establishing a connection. It's important to avoid common but polarizing tropes from popular media, and often quite helpful to frame climate issues in novel or unexpected ways that cut across entrenched political discourse. Emerging social science research Beyond ideology, climate change is Simple, Serious, and Solvable. Effective communication of these three key ideas can succeed when the science argument is carefully framed to avoid attack of the audience's ethical identity. Simple arguments from common sense and everyday experience are more successful than data. Serious consequences to values that resonate with the audience can be avoided by solutions that don't threaten those values.

  2. Short communication: Interaction of the isomers carvacrol and thymol with the antibiotics doxycycline and tilmicosin: In vitro effects against pathogenic bacteria commonly found in the respiratory tract of calves.

    Bovine respiratory disease is the major problem faced by cattle, specially calves, leading to reduced animal performance and increased mortality, consequently causing important economic losses. Hence, calves must be submitted to antibiotic therapy to counteract this infection usually initiated by the combination of environmental stress factors and viral infection, altering the animal's defense mechanism, and thus allowing lung colonization by the opportunistic bacteria Mannheimia haemolytica and Pasteurella multocida. Essential oils appear to be candidates to replace antibiotics or to act as antibiotic adjuvants due to their antimicrobial properties. In the present study, we aimed to evaluate the 4 essential oil components carvacrol, thymol, trans-anethole, and 1,8 cineole as antibacterial agents or as adjuvants for the antibiotics doxycycline and tilmicosin against M. haemolytica and P. multocida. Bacteria were cultured according to standard protocols, followed by the determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration. A checkerboard assay was applied to detect possible interactions between components, between antibiotics, and between components and antibiotics. Doxycycline at 0.25 and 0.125 μg/mL inhibited the growth of P. multocida and M. haemolytica, respectively, whereas tilmicosin MIC values were 1.0 and 4.0 μg/mL for P. multocida and M. haemolytica, respectively. Carvacrol MIC values were 2.5 and 1.25 mM for P. multocida and M. haemolytica, respectively, whereas thymol MIC values were 1.25 and 0.625 mM for P. multocida and M. haemolytica, respectively. Trans-anethole and 1,8 cineole did not present any antibacterial effect even at 40 mM against the investigated pathogens. All minimum bactericidal concentration values were the same as MIC, except when thymol was tested against M. haemolytica, being twice the MIC data (i.e., 1.25 mM thymol). Based on fractional inhibitory concentration checkerboard assay, no

    Cardiovascular repair and myocardial contractility may be improved by migration of bone marrow stem cells (BMSC) and their delivery to the site of injury, a process known as BMSC homing. The aim of our study was to examine the dietary effect of a newly patented depurinized milk (DP) that is almost free of uric acid and purine and pyrimidine compounds compared with a standard commercial 1.5% fat UHT milk diet or allopurinol therapy in rat experimental hyperuricemia. Bone marrow stem cell potential (BMCD34(+), CD34-postive bone marrow cells), plasma oxidative stress parameters [advanced oxidation protein products, AOPP) and thiobarbituric acid reactive substances (TBARS)], myocardial damage markers [creatine phosphokinase (CPK), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH)], plasma cholesterol, and high-density lipoprotein cholesterol were investigated. The DP milk diet significantly increased the number of BMCD34(+) stem cells compared with commercial UHT milk. Allopurinol given alone also increased the number of BMCD34(+). Hyperuricemia caused a significant increase in all plasma enzyme markers for myocardial damage (CPK, LDH, and AST). A cardioprotective effect was achieved with allopurinol but almost equally with DP milk and more than with commercial milk. Regarding plasma AOPP, TBARS, and cholesterol levels, the most effective treatment was DP milk. In conclusion, the protective role of a milk diet on cardiovascular function may be enhanced through the new depurinized milk diet, which may improve cardiovascular system function via increased bone marrow stem cell regenerative potential, decreased plasma oxidative stress parameters, and decreased levels of myocardial damage markers and cholesterol. New dairy technology strategies focused on eliminating harmful milk compounds should be completely nontoxic. Novel milk products should be tested for their ability to improve tissue repair and function. Copyright © 2014 American Dairy Science

  4. Short communication: Multi-scale topographic anisotropy patterns on a Barrier Island

    2017-11-01

    Barrier islands exhibit a range of landforms that reflect the complex and varied combination of coastal and aeolian processes realized over the evolution of the island. A detailed analysis of the topography can be used to describe the evolution of a barrier island and provide insight on how it may be affected by a change in sea level, storm activity and wind exposure patterns. Topographic anisotropy, or the directional dependence of relief of landforms, can be used to determine the relative importance of different processes to island evolution at a range of scales. This short communication describes the use of scale-dependent topographic anisotropy to characterize the structure of Santa Rosa Island in northwest Florida. Scale-dependent topographic relief and asymmetry were assessed from a LiDAR-derived DEM from May 2004, a few months before the island experienced widespread erosion and overwash during Hurricane Ivan. This application demonstrates how anisotropy can be used to identify unique scale-dependent structures that can be used to interpret the evolution of this barrier island. Results of this preliminary study further highlight the potential of using topographic anisotropy to controls on barrier island response and recovery to storms as well as island resiliency with sea level rise and storm activity.

  5. Short communication: Effect of casein haplotype on angiotensin-converting enzyme inhibitory and antioxidant capacities of milk casein from Italian Holstein cows before and following in vitro digestion with gastrointestinal enzymes.

    The aim of this work was to investigate the effect of casein haplotype (αS1, β, and κ) on antioxidative and angiotensin-converting enzyme (ACE) inhibitory capacities of milk casein from Italian Holstein cows before and following in vitro digestion with gastrointestinal enzymes. The antioxidant capacity was measured using 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid and ferric-reducing antioxidant power assays, whereas ACE inhibition was determined by ACE-inhibitory assay. The ACE-inhibitory and antioxidant capacities of milk casein increased during in vitro gastrointestinal digestion. Casein haplotype significantly influenced the antioxidative and ACE-inhibitory capacities of digested casein. In particular, BB-A(2)A(1)-AA casein and BB-A(1)A(1)-AA casein showed the highest ACE-inhibitory capacity, BB-A(2)A(2)-AA casein showed the highest antioxidant capacity, whereas BB-A(2)A(2)-BB casein showed the lowest biological capacity. To date, few studies have been done on the effect of casein haplotype on biological capacity of milk casein, thus the present study sets the basis for a new knowledge that could lead to the production of milk with better nutraceutical properties.

    Nitrate decreases enteric CH4 production in ruminants, but may also negatively affect fiber degradation. In this experiment, 28 lactating Holstein dairy cows were grouped into 7 blocks. Within blocks, cows were randomly assigned to 1 of 4 isonitrogenous treatments in a 2×2 factorial arrangement: control (CON); NO3 [21g of nitrate/kg of dry matter (DM)]; DHA [3g of docosahexaenoic acid (DHA)/kg of DM]; or NO3+DHA (21g of nitrate/kg of DM and 3g of DHA/kg of DM). Cows were fed a total mixed ration consisting of 21% grass silage, 49% corn silage, and 30% concentrates on a DM basis. Based on the difference in natural (13)C enrichment and neutral detergent fiber and starch content between grass silage and corn silage, we investigated whether a negative effect on rumen fiber degradation could be detected by evaluating diurnal patterns of (13)C enrichment of exhaled carbon dioxide. A significant nitrate × DHA interaction was found for neutral detergent fiber digestibility, which was reduced on the NO3 treatment to an average of 55%, as compared with 61, 64, and 65% on treatments CON, DHA, and NO3+DHA, respectively. Feeding nitrate, but not DHA, resulted in a pronounced increase in (13)C enrichment of CO2 in the first 3 to 4 h after feeding only. Results support the hypothesis that effects of a feed additive on the rate of fiber degradation in the rumen can be detected by evaluating diurnal patterns of (13)C enrichment of CO2. To be able to detect this, the main ration components have to differ considerably in fiber and nonfiber carbohydrate content as well as in natural (13)C enrichment.

    Scientific, technological and methodological knowledge regarding the risks caused by natural events are in continuous evolution. A careful analysis of the communication and information, practiced by administrations and institutions involved in the decision-making processes, show a peculiar difference between the quality of the theoretical-operating level and the effectiveness of communication systems of the risk obtained. This is the level which involves directly citizens and institutions and needs, therefore, an efficacious and shared system whose aim is to inform the whole community, in a simple and clear way, during the different phases correlated to the environmental risk. The hypotesis is, in fact, to create a distinct typology of message, corresponding to each phase: • prevention of the risk > sensitization > information. If the potential risk is imminent or changes into real emergency, it is necessary to plan a communication aimed at supporting a very fast alarm to the community. • anticipation of the risk > pre-alert > information • imminence of the risk > alert > alarm • post-event /risk > information > precept and rules. The lack of a uniform and coerent planning process, both on the linguistic field (the typology of the message, iconic and verbal) and technical (the typology of supports) it is clear analysing the reference scenario in Italy. This involves the creation of deeply discordant systems which don't communicate the different typologies of risk efficaciously during distinct moments. To come to a systemic vision of the problem we proceed to collect and to obtain documentation about the "alarm" and communication systems existing in Italy nowadays. So we will have a classification of the different typologies about natural risk and communication systems related to them. The aim of this research is to propose a rationalization and a standard coding of signals. The logical conclusion of this course can be the creation of a national

    Credibility can be enhanced and communication can be made somewhat more effective by informally talking to a small group of people as opposed to speaking to large groups. The more informal the situation can be, and the approximation of a one-to-one speaker-to-audience ratio assists the audience in obtaining a feeling they are being treated equitably. This also assists the speaker in getting a feel for the chief concerns of that particular audience. The authors have also found that this same principle has worked rather well in dealing with the media. So far they have experienced fewer mistakes and fewer sensationalisms from the media personnel with which they have had the opportunity to sit down one-on-one and explain the program. The media reaches a much greater segment of the public than any of us as individuals, and an informed media can communicate much more effectively with the public than an uninformed one

    We conducted mental health training incorporating active listening for managers at a site of a general chemical company with 1,400 employees. Our purpose was to clarify the effect of active listening training of 2.5h. All subjects were managers. The mental health training was given to 229 managers, 21 times from May 2007 until March 2008. Surveys were conducted from May 2007 to September 2008. The training sessions were conducted in a company meeting room, starting at 2:00 p.m. The importance and significance of listening as a mental health measure and methods of active listening were explained in the training. Afterward, role-playing and follow-up discussions were done twice each. In summaries, participants wrote down what they noticed about listening and gave group presentations. The instructor commented on the presentations, and ended the session by passing out and explaining a paper summarizing what is important in listening. The training was evaluated with a questionnaire distributed at the completion of training, and questionnaires on implementation of what was learned were distributed 1, 3, and 6 mo later. The Active Listening Attitude Scale (ALAS; composed of two scales for method of listening and listening attitude) developed by Mishima et al. was also used before and 1, 3, and 6 mo after the training. In questionnaires distributed on the same day after training, 60% of the 212 respondents said the training time was just right, and 30.1% felt it was too short. The difficulty level of the training was considered appropriate by 77.8%, and 79.7% intended to implement what they had learned. Overall satisfaction was high at 85.9%. In the questionnaire 6 mo after training, 81.4% of the 145 respondents remembered the content of the training and 49.7% said they were practicing what they had learned. They responded that their conversations with subordinates about non-work topics had increased, and communication and support at work had become smoother. ALAS was

  20. Shared language:Towards more effective communication.

    Science.gov (United States)

    Thomas, Joyce; McDonagh, Deana

    2013-01-01

    The ability to communicate to others and express ourselves is a basic human need. As we develop our understanding of the world, based on our upbringing, education and so on, our perspective and the way we communicate can differ from those around us. Engaging and interacting with others is a critical part of healthy living. It is the responsibility of the individual to ensure that they are understood in the way they intended.Shared language refers to people developing understanding amongst themselves based on language (e.g. spoken, text) to help them communicate more effectively. The key to understanding language is to first notice and be mindful of your language. Developing a shared language is an ongoing process that requires intention and time, which results in better understanding.Shared language is critical to collaboration, and collaboration is critical to business and education. With whom and how many people do you connect? Your 'shared language' makes a difference in the world. So, how do we successfully do this? This paper shares several strategies.Your sphere of influence will carry forward what and how you are communicating. Developing and nurturing a shared language is an essential element to enhance communication and collaboration whether it is simply between partners or across the larger community of business and customers. Constant awareness and education is required to maintain the shared language. We are living in an increasingly smaller global community. Business is built on relationships. If you invest in developing shared language, your relationships and your business will thrive.

  1. Effective communication and supervision in the biomedical engineering department.

    Science.gov (United States)

    Xu, Y; Wald, A; Cappiello, J

    1997-01-01

    It is important for biomedical engineering supervisors to master the art of effective communication. Supervisors who have effective communication skills can successfully initiate creative programs and generate a harmonious working atmosphere. Using effective communication, they can promote good working conditions, such as high morale, worker initiative and loyalty to the department, which are almost impossible to measure but imperative for a successful department. However, effective communication tends to be neglected by supervisors who are either functional specialists or managerial generalists. This paper presents several cases of what effective communication truly is and discusses some potential factors that may lead to ineffective communication.

  2. Short communications published online in the British Journal of Oral and Maxillofacial Surgery during 2010-2011.

    Colbert, S; Southorn, B; Rosenbaum, G; Aldridge, T; Brennan, P A

    2012-09-01

    The British Journal of Oral and Maxillofacial Surgery (BJOMS) publishes many types of papers including original articles, review articles, and short communications. Many of the latter are isolated case reports of rare or interesting diseases or of difficult or unexpected complications. While case reports are sometimes considered to be of little educational or clinical value, and as such do little to advance medical knowledge, they do have an important role, and many trainees begin their publishing careers writing such papers. There is increasing pressure for space in paper medical journals and, for this reason, some journals either limit or do not publish short publications in print copy but instead put them online. Using established criteria, we previously evaluated all 142 short communications published in the BJOMS during 2008-2009 and found that 48% of them had little or no educational value. As a result, the editorial board of BJOMS took the decision to publish most short communications online only. We have now analysed 48 short communications that were published online only during 2010-2011. Most (80%) were single case reports that covered virtually the whole remit of the specialty, and over half (56%) were published by authors based in the UK. While many of these papers did not add important new information to existing knowledge, these types of article are clearly of value both for trainees and for experienced surgeons. We think that these should continue to be supported as, in addition to their educational value, they are an excellent way for trainees to start to write.

    Giroldi, Esther; Veldhuijzen, Wemke; Bareman, Frits; Bueving, Herman; van der Weijden, Trudy; van der Vleuten, Cees; Muris, Jean

    2016-01-01

    Consultations with talkative patients present a challenge to doctors. It is difficult to gather all the necessary information within the available time, without damaging the doctor-patient relationship. Based on the listed existing literature and doctors' experiences, we present ten tips for gathering information from talkative patients in an effective manner whilst maintaining a good therapeutic alliance. In consultations with talkative patients, it is important to explore the cause of patients' talkativeness and to adapt one's communication approach accordingly.- Familiar communication strategies such as 'summarizing' can still be applied. When taking this route, a more directive communication approach--e.g. by means of a 'closed-ended summary'--can prevent the patient interrupting the doctor or departing from his subject. There are strategies aimed at avoiding a damaging effect to the doctor-patient relationship when applying this approach: don't be overly directive, make the patient co-responsible for efficient time management in the consultation, and make use of empathic interrupting and humour.

  5. Effective communications bring greater public acceptance

    Clawson, C.

    1992-01-01

    In 1986, GPU Nuclear Corporation announced a plan to evaporate into the atmosphere 2.3 million gal of water remaining from the Three Mile Island Unit 2 (TMI-2) accident. The water would be processed to remove most of the radioactivity, but still remaining were >1,000 Ci of tritium to be released to the atmosphere during the evaporation process. It was expected that, following regulatory approvals, it would take >2 yr to complete the process. Fed by well-established antinuclear groups, public concern about evaporating the TMI-2-accident-generated water ran high among residents living near the plant. In the years since the TMI-2 accident, GPU Nuclear had developed a highly effective communications program in the communities surrounding TMI. This ongoing program provided a solid foundation on which to create and implement a risk communications approach to community understanding and acceptance of the evaporation process

    Carpentier, Sarah M; Moreno, Sylvain; McIntosh, Anthony R

    2016-10-01

    Musical training is frequently associated with benefits to linguistic abilities, and recent focus has been placed on possible benefits of bilingualism to lifelong executive functions; however, the neural mechanisms for such effects are unclear. The aim of this study was to gain better understanding of the whole-brain functional effects of music and second-language training that could support such previously observed cognitive transfer effects. We conducted a 28-day longitudinal study of monolingual English-speaking 4- to 6-year-old children randomly selected to receive daily music or French language training, excluding weekends. Children completed passive EEG music note and French vowel auditory oddball detection tasks before and after training. Brain signal complexity was measured on source waveforms at multiple temporal scales as an index of neural information processing and network communication load. Comparing pretraining with posttraining, musical training was associated with increased EEG complexity at coarse temporal scales during the music and French vowel tasks in widely distributed cortical regions. Conversely, very minimal decreases in complexity at fine scales and trends toward coarse-scale increases were displayed after French training during the tasks. Spectral analysis failed to distinguish between training types and found overall theta (3.5-7.5 Hz) power increases after all training forms, with spatially fewer decreases in power at higher frequencies (>10 Hz). These findings demonstrate that musical training increased diversity of brain network states to support domain-specific music skill acquisition and music-to-language transfer effects.

    The aim of this study is to evaluate the capacity of a laser, delivering very short pulses in the near infrared spectrum with a high pulse ratio frequency, to induce genetic modification on biological tissues. Chromatid exchanges and chromosomal aberrations studies are used to test potential effect on human lymphocytes. The laser irradiation induces a significant increase of acentric fragments but the absence of dicentric suggests that a repetitive very short pulses irradiation has a relatively low capacity to induce genetic abnormalities.

  14. Short communication: Determination of Salmonella clustered regularly interspaced short palindromic repeats (CRISPR) diversity on dairy farms in Wisconsin and Minnesota.

    Science.gov (United States)

    Wehnes, C A; Rehberger, T G; Barrangou, R; Smith, A H

    2014-10-01

    Salmonella enterica ssp. enterica is a foodborne pathogen able to cause disease in both humans and animals. Diverse serovars of this pathogen exist, some of which are host specific, causing a range of clinical symptoms from asymptomatic infection through morbidity and mortality. According to a 2007 survey by the USDA National Animal Health Monitoring System, fecal shedding of Salmonella from healthy cows occurs on 39.7% of dairy farms in the United States. Certain serovars are frequently isolated from dairy farms and the majority of isolates from the National Animal Health Monitoring System study were represented by 5 serovars; however, genotypic diversity was not examined. The objective of this study was to determine the diversity of clustered regularly interspaced short palindromic repeats (CRISPR) loci in Salmonella collected from 8 dairy farms with a previous history of salmonellosis. None of the cows or calves sampled on 2 of the 8 dairy farms were shedding Salmonella, although Salmonella was detected in a cow bedding sample on 1 of these farms. Salmonella populations were discrete on each farm, according to CRISPR typing, with the exception of an Anatum var. 15+ type on farms 5 and 6 and the Montevideo type on farms 1 and 2. One to 4 distinct CRISPR genotypes were identified per farm. The CRISPR typing differed within serovars, as Montevideo, Anatum var. 15+, and Muenster serovars had no overlap of spacer content, even on the same farm, reflecting between- and within-serovar genetic diversity. The dynamic nature of Salmonella populations was shown in a farm that was sampled longitudinally over 13.5 mo. Changes in serovar from 3,19:-:z27 to Montevideo was observed between the first sampling time and 8 mo later, with concomitant change in CRISPR alleles. The results indicate that Salmonella strains present in smaller dairy herds (<500 head) are specific to that farm and new Salmonella strains may emerge over time.

    2015-04-01

    This study investigated the effect of exposing heifers to individual feed components on the extent and pattern of feed sorting upon transition to a novel ration. Holstein heifers (394 ± 62 d old, weighing 409.8 ± 37.3 kg; mean ± SD), consuming a familiar mixed silage-based ration [55% corn silage and 45% haylage, dry matter (DM) basis], were transitioned to a novel total mixed ration [TMR; 41.6% haylage, 36.5% corn silage, 14.6% high-moisture corn, and 7.3% protein supplement, DM basis] by 1 of 2 treatments: direct transition to novel TMR (DIR; n = 5) or exposure to novel TMR components individually before receiving novel TMR (COM; n = 6). During the baseline period (d 1 to 4), all heifers were offered the familiar silage-based ration. During transition (d 5 to 12), DIR heifers received the novel TMR, whereas COM heifers received the novel TMR components offered separately, in amounts according to TMR composition (target 15% orts). After transition (d 13 to 20), all heifers received the novel TMR. Feed intake and feeding time were determined daily and fresh feed and individual orts were sampled every 2d for particle size analysis and neutral detergent fiber content. The particle size separator consisted of 3 screens (18, 9, and 1.18 mm) and a bottom pan, resulting in 4 fractions (long, medium, short, and fine). Sorting activity for each fraction was calculated as actual intake expressed as a percentage of predicted intake. We detected no effect of treatment on dry matter intake or feeding time. After transition to the novel TMR, COM heifers sorted to a greater extent than did DIR heifers, sorting against long particles (95.4 vs. 98.9%) and for short particles (101.7 vs. 100.6%). Differences in sorting patterns resulted in COM heifers tending to have lower neutral detergent fiber intake as a percentage of predicted intake (98.9 vs. 100.5%). The results of this study suggest that the degree of feed sorting may be influenced by method of transition to a novel

  3. Short communication: Short and long-term efficacy and phytotoxicity of phosphine against Rhynchophorus ferrugineus in live Phoenix canariensis palms

    Directory of Open Access Journals (Sweden)

    Óscar Dembilio

    2015-12-01

    Full Text Available The red palm weevil, Rhynchophorus ferrugineus, is a palm borer native to South Asia which has spread mainly due to the unintended movement of infested planting material. As a result, this species has become the most destructive palm pest in the world. The difficulty of detecting the early stages of infestation due to its cryptic life cycle has led many countries to implement, strict pre- and post-entry quarantine regulations to prevent further spread. However, there are no quarantine protocols to ensure that palm material for planting is free of R. ferrugineus. The aim of this study has been to determine the efficacy of aluminium phosphide as a safe quarantine treatment against different stages of R. ferrugineus and the possible phytotoxic effects on live Phoenix canariensis palms. Our results confirm that a dose of 1.14 g/m3 for 2 days is enough to kill all stages of R. ferrugineus in live palms with no phytotoxic effects on treated palms for up to one year after the treatment. This procedure, which could be easily applied in sealed containers used for palm trade, could drastically reduce risks associated to palm movement worldwide.

  8. Short- and long-term effects of unemployment on fertility

    Science.gov (United States)

    Currie, Janet; Schwandt, Hannes

    2014-01-01

    Scholars have been examining the relationship between fertility and unemployment for more than a century. Most studies find that fertility falls with unemployment in the short run, but it is not known whether these negative effects persist, because women simply may postpone childbearing to better economic times. Using more than 140 million US birth records for the period 1975–2010, we analyze both the short- and long-run effects of unemployment on fertility. We follow fixed cohorts of US-born women defined by their own state and year of birth, and relate their fertility to the unemployment rate experienced by each cohort at different ages. We focus on conceptions that result in a live birth. We find that women in their early 20s are most affected by high unemployment rates in the short run and that the negative effects on fertility grow over time. A one percentage point increase in the average unemployment rate experienced between the ages of 20 and 24 reduces the short-run fertility of women in this age range by six conceptions per 1,000 women. When we follow these women to age 40, we find that a one percentage point increase in the unemployment rate experienced at ages 20–24 leads to an overall loss of 14.2 conceptions. This long-run effect is driven largely by women who remain childless and thus do not have either first births or higher-order births. PMID:25267622

    Effective communication by nursing home staff is related to a higher quality of life and a decrease in verbal and physical aggression and depression in nursing home residents. Several communication intervention studies have been conducted to improve communication between nursing home staff and nursing home residents with dementia. These studies have shown that communication skills training can improve nursing aides’ communication with nursing home residents. However, these studies tended to be time-consuming and fairly difficult to implement. Moreover, these studies focused on the communicative benefits for the nursing home residents and their well-being, while benefits and well-being for the nursing aides were neglected. The current study focused on implementing a brief communication skills training program to improve nursing aides’ (N=24) communication with residents with dementia (N=26) in a nursing home. The effects of the training on nursing aides’ communication, caregiver distress, and job satisfaction and residents’ psychopathology and agitation were assessed relative to a control group condition. Nursing aides in the intervention group were individually trained to communicate effectively with residents during morning care by using short instructions, positive speech, and biographical statements. Mixed ANOVAs showed that, after training, nursing aides in the intervention group experienced less caregiver distress. Additionally, the number of short instructions and instances of positive speech increased. Providing nursing aides with helpful feedback during care aids communication and reduces caregiver burden, even with a brief intervention that requires limited time investments for nursing home staff.

    2014-02-01

    Physicians' ability to effectively and compassionately communicate information is key to a successful patient-physician relationship. The current health care environment demands increasing clinical productivity and affords less time with each patient, which can impede effective patient-physician communication. The use of patient-centered interviewing, caring communication skills, and shared decision making improves patient-physician communication. Involving advanced practice nurses or physician assistants may improve the patient's experience and understanding of her visit. Electronic communication with established patients also can enhance the patient experience in select situations.

    The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. The program is in its third year. More than 75 students participated in a guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Three Colleges were involved in the program: Engineering, Education, and Science.

    An off-the-shelf green laser diode (LD) was measured to investigate its temperature dependent characteristics. Performance of the device was severely restricted by rising temperature in terms of increasing threshold current and decreasing modulation bandwidth. The observation reveals that dynamic characteristics of the LD is sensitive to temperature. Influence of light attenuation on the modulation bandwidth of the green LD was also studied. The impact of light attenuation on the modulation bandwidth of the LD in short and low turbid water channel was not obvious while slight difference in modulation bandwidth under same injection level was observed between water channel and free space even at short range.

  6. THE ARCHITECTURE OF THE STORYTELLING ART: THE SOCIOLOGICAL NATURE AND THE AESTHETIC COMMUNICATION IN THE BRAZILIAN CONTEMPORARY SHORT STORY

    Directory of Open Access Journals (Sweden)

    Márcia Adriana Dias Kraemer

    2016-12-01

    Full Text Available This article presents reflections about studies of real texts belonging to the genre Brazilian contemporary short stories in its sociological and aesthetic nature. To unveil the path of research, we analyzed the production process of literary texts, focusing on the short story. We assessed predominant aspects of the creative context, the thematic approach, the compositional construction, and style of this genre. Under a materialist and dialectics view, we believe that the discursive genre short story constitutes, according to Bakhtin, a historical and real activity of reading and writing; with relatively stable characteristics, it is linked to a typical state of social communication; with its thematic, stylistic, and compositional traits related to individual statements, linked to human activity. The literary aspects of this genre, under the perspective of Applied Linguistics and Dialogic Discourse Analysis, reveal the various movements in the dynamics of verbal interaction. Therefore, when we reflect on the contemporary Brazilian short story, we may measure the importance of its recognition for reading as construction of meanings. This is a theoretical research, with qualitative analysis of data generation, explanatory purposes and dialectical approach method.

    Despite the fact that chlorinated paraffins have been produced in relatively large amounts, and high concentrations have been found in sewage sludge applied to soils, there is little information on their concentrations in soils and the effect on soil organisms. The aim of this study was to investigate the toxicity of chlorinated paraffins in soils. The effects of short-chain chlorinated paraffins (64% chlorine content) on invertebrates (Eisenia fetida, Folsomia candida, Enchytraeus albidus, Enchytraeus crypticus, Caenorhabditis elegans) and substrate-induced respiration of indigenous microorganisms were studied. Differences were found in the sensitivity of the tested organisms to short-chain chlorinated paraffins. F. candida was identified as the most sensitive organism with LC(50) and EC(50) values of 5733 and 1230 mg/kg, respectively. Toxicity results were compared with available studies and the predicted no effect concentration (PNEC) of 5.28 mg/kg was estimated for the soil environment, based on our data.

  8. On cost-effective communication network designing

    Science.gov (United States)

    Zhang, Guo-Qiang

    2010-02-01

    How to efficiently design a communication network is a paramount task for network designing and engineering. It is, however, not a single objective optimization process as perceived by most previous researches, i.e., to maximize its transmission capacity, but a multi-objective optimization process, with lowering its cost to be another important objective. These two objectives are often contradictive in that optimizing one objective may deteriorate the other. After a deep investigation of the impact that network topology, node capability scheme and routing algorithm as well as their interplays have on the two objectives, this letter presents a systematic approach to achieve a cost-effective design by carefully choosing the three designing aspects. Only when routing algorithm and node capability scheme are elegantly chosen can BA-like scale-free networks have the potential of achieving good tradeoff between the two objectives. Random networks, on the other hand, have the built-in character for a cost-effective design, especially when other aspects cannot be determined beforehand.

    The physical examination of patients is an important diagnostic competence, but little is known about the examination skills of final-year medical students. To investigate physical examination skills of final-year medical students. In a cross-sectional study, 40 final-year students were asked to perform a detailed physical examination on standardized patients. Their performances were video-recorded and rated by independent video assessors. Video ratings showed a mean success rate of 40.1 % (SD 8.2). As regards accompanying doctor-patient communication, final-year students achieved a mean of no more than 36.7 % (SD 8.9) in the appropriate use of the corresponding communication items. Our study revealed severe deficits among final-year medical students in performing a detailed physical examination on a standardized patient. Thus, physical examination skills training should aim to improve these deficits while also paying attention to communicative aspects. Copyright © 2015. Published by Elsevier GmbH.

    We investigated implicit communication strategies for anticipatory information sharing during team performance of tasks with varying degrees of complexity. We compared the strategies used by teams with the highest level of performance to those used by the lowest-performing teams to evaluate the frequency and methods of communications used as a function of task structure. High-performing teams share information by anticipating the needs of their teammates rather than explicitly requesting the exchange of information. As the complexity of a task increases to involve more interdependence among teammates, the impact of coordination on team performance also increases. This observation motivated us to conduct a study of anticipatory information sharing as a function of task complexity. We conducted an experiment in which 13 teams of four people performed collaborative search-and-deliver tasks with varying degrees of complexity in a simulation environment. We elaborated upon prior characterizations of communication as implicit versus explicit by dividing implicit communication into two subtypes: (a) deliberative/goal information and (b) reactive status updates. We then characterized relationships between task structure, implicit communication, and team performance. We found that the five teams with the fastest task completion times and lowest idle times exhibited higher rates of deliberative communication versus reactive communication during high-complexity tasks compared with the five teams with the slowest completion times and longest idle times (p = .039). Teams in which members proactively communicated information about their next goal to teammates exhibited improved team performance. The findings from our work can inform the design of communication strategies for team training to improve performance of complex tasks. © 2016, Human Factors and Ergonomics Society.

    Hosoda, Akira; Sadatsuki, Yoshitomo; Oshima, Akihiro; Ishii, Akina; Tsubaki, Tatsuya

    The aim of this research is to clarify the mechanism of controlling plastic shrinkage crack by adding small amout of synthetic short fiber, and to propose optimum polypropylene short fiber to control plastic shrinkage crack. In this research, the effect of the hydrophily of polypropylene fiber was investigated in the amount of plastic shrinkage of mortar, total area of plastic shrinkage crack, and bond properties between fiber and mortar. The plastic shrinkage test of morar was conducted under high temperature, low relative humidity, and constant wind velocity. When polypropylene fiber had hydrophily, the amount of plastic shrinkage of mortar was restrained, which was because cement paste in morar was captured by hydrophilic fiber and then bleeding of mortar was restrained. With hydrophily, plastic shrinkage of mortar was restrained and bridging effect was improved due to better bond, which led to remarkable reduction of plastic shrinkage crack. Based on experimental results, the way of developing optimum polypropylene short fiber for actual construction was proposed. The fiber should have large hydrophily and small diameter, and should be used in as small amount as possible in order not to disturb workability of concrete.

    This paper reports the evaluation of a European funded 3-week summer school which took place in 2013 involving 60 staff and students from five universities. The evaluation looked at one group in detail using a qualitative approach to consider whether students and teachers can work together in multicultural groups in order to achieve their goal. Method: One group was observed during 2 two-hour sessions of group activity; at the beginning and end of the summer school task. Video data was analysed using the Rapport Management framework, a model of cross-cultural communication, to determine what motivated this group's interactions. Results: As the group's deadline became imminent ‘face-threatening acts’ (FTAs) were more apparent. These were tolerated in this group because of the development of a strong social bond. There was inequity in participation with members of the group falling into either high- or low-involvement categories. This was also well-tolerated but meant some students may not have gained as much from the experience. The group lacked guidance on managing group dynamics. Conclusion: Cultural differences in communication were not the main threat to multi-cultural working groups. Potential problems can arise from failing to provide the group with a framework for project and team management. An emphasis on ground rules and the allocation of formal roles is important as is the encouragement of socialisation which supports the group during challenging times

  4. Social Barriers to Effective Communication in Old Age

    Directory of Open Access Journals (Sweden)

    Anna Sanecka

    2014-12-01

    Full Text Available Some communication barriers apply particularly to elderly people. The social barriers to effective communication in old age are the barriers caused by stereotypes of old age/elderly people and the barriers arising from limitations in using mass communication by seniors. Stereotypes of old age/elderly people embrace views regarding old people’s communication skills and the ideas about the correct way of communication with them. Therefore the communication problems of old people are correlated with the little and poor communication processes they are participating in. This seems to be a result of impetuses of poor quality sent to seniors by their communication partners. Not only face to face communication but also mass communication is very important for the elderly population. Therefore limitations in using new technologies and new communication channels as well as a limited presence in the mass media of content created by seniors and for seniors have an impact on their life, their well-being, and their interpersonal relationships. These problems are especially important when we faced with the ever growing population of elderly people.

    2014-09-30

    Use of effective interpersonal communication strategies by nurses in both personal and professional settings, may reduce stress, promote wellness, and therefore, improve overall quality of life. This article briefly explores the concept of interpersonal communication as it relates to Maslow's hierarchy of human needs; describes personal variables and the interaction of internal and external variables that can impact communication; and discusses possible causes and consequences of ineffective communication. Drawing on both the literature and experiences as a longtime provider of care in the mental health field, the author offers multiple practical strategies, with specific examples of possible responses for effective communication. Recommendations in this article are intended for nurses to consider as they seek healthy communication strategies that may be useful in both their personal and professional lives.

    Gorin, Simon; Mengal, Pierre; Majerus, Steve

    2018-07-01

    Recent theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain.

    2007-01-01

    In order to estimate typical radio frequency exposures from indoor used wireless communication technologies applied in homes and offices, WLAN, Bluetooth and Digital Enhanced Cordless Telecommunications systems, as well as baby surveillance devices and wireless headphones for indoor usage, have been investigated by measurements and numerical computations. Based on optimised measurement methods, field distributions and resulting exposure were assessed on selected products and real exposure scenarios. Additionally, generic scenarios have been investigated on the basis of numerical computations. The obtained results demonstrate that under usual conditions the resulting spatially (over body dimensions) averaged and 6-min time-averaged exposure for persons in the radio frequency fields of the considered applications is below ∼0.1% of the reference level for power density according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines published in 1998. Spatial and temporal peak values can be considerably higher by 2-3 orders of magnitude. In case of some transmitting devices operated in close proximity to the body (e.g. WLAN transmitters), local exposure can reach the same order of magnitude as the basic restriction; however, none of the devices considered in this study exceeded the limits according to the ICNIRP guidelines.

    Marketing managers continually struggle with how to maximize the effects of an integrated marketing communications strategy. The growing number of available communication outlets, as well as highly varying competitive landscapes, adds further complexity to this challenge. This empirical study examines the differential impact within a pharmaceutical market therapeutic category where both "push" and "pull" communication strategies operate on consumers and gatekeepers alike, in an atmosphere of unrelenting product innovation and broad competition. Furthermore, we explore how two contingency variables-(a) the competitive landscape, and (b) the product's length of time on the market-interact with these communication efforts and affect brand and category sales.

    Full Text Available Effective communication is essential to the practice of pediatric oncology. Clear and empathic delivery of diagnostic and prognostic information positively impacts the ways in which patients and families cope. Honest, compassionate discussions regarding goals of care and hopes for patients approaching end of life can provide healing when other therapies have failed. Effective communication and the positive relationships it fosters also can provide comfort to families grieving the loss of a child. A robust body of evidence demonstrates the benefits of optimal communication for patients, families, and healthcare providers. This review aims to identify key communication skills that healthcare providers can employ throughout the illness journey to provide information, encourage shared decision-making, promote therapeutic alliance, and empathically address end-of-life concerns. By reviewing the relevant evidence and providing practical tips for skill development, we strive to help healthcare providers understand the value of effective communication and master these critical skills.

    Full Text Available Introduction. The link between patient-clinician communication and its effect on clinical outcomes is an important clinical issue that is yet to be elucidated. Objective. Investigating if communication type (positive or neutral about the expected treatment outcome affected (i participants’ expectations and (ii short-term relaxation effects in response to genuine or sham acupuncture and investigating if expectations were related to outcome. Methods. Healthy volunteers (n=243, mean age of 42 were randomized to one treatment with genuine or sham acupuncture. Within groups, participants were randomized to positive or neutral communication, regarding expected treatment effects. Visual Analogue Scales (0–100 millimeters were used to measure treatment expectations and relaxation, directly before and after treatment. Results. Participants in the positive communication group reported higher treatment expectancy, compared to the neutral communication group (md 12 versus 6 mm, p=0.002. There was no difference in relaxation effects between acupuncture groups or between communication groups. Participants with high baseline expectancy perceived greater improvement in relaxation, compared to participants with low baseline levels (md 27 versus 15 mm, p=0.022. Conclusion. Our data highlights the importance of expectations for treatment outcome and demonstrates that expectations can be effectively manipulated using a standardized protocol that in future research may be implemented in clinical trials.

    The shortening of harvest time attained in hedgerow olive (Olea europaea L.) orchards represents an advantage for the adoption of this cropping system in areas that are prone to suffer frost during the harvest period. To establish an optimal harvesting window, we carried out a study of the fruit ripening process on a hedgerow orchard of Arbequina olive trees, located in Zaragoza (Spain). From 2007 to 2009, oil accumulation on the fruit (% of dry weight) and oil yield (grams of oil per 100 fruits) were monitored, from early September to late November. Over the three years both variables peaked around November 15th, indicating that Arbequina reached full ripening earlier than has been reported previously for this variety. In two of the three seasons the orchard suffered several frosts during November. Long term climatic data from this area indicated that the risk of early frosts (< -2 degree centigrade) increases as November progresses with a high risk after November 20{sup t}h. In conclusion, the optimal harvesting period for Arbequina in this area should not extend beyond November 20{sup t}h. A rapid harvesting before this date is advisable to avoid the risk of damage caused by early frost in Zaragoza. Hedgerow planting provides an additional advantage in frost-prone areas, because mechanization of operations permits a short harvest period, easier to fit into the optimal harvesting window.

  6. A UHF RFID system with on-chip-antenna tag for short range communication

    International Nuclear Information System (INIS)

    Peng Qi; Zhang Chun; Zhao Xijin; Wang Zhihua

    2015-01-01

    A UHF RF identification system based on the 0.18 μm CMOS process has been developed for short range and harsh size requirement applications, which is composed of a fully integrated tag and a special reader. The whole tag chip with the antenna takes up an area of 0.36 mm 2 , which is smaller than other reported tags with an on-chip antenna (OCA) using the standard CMOS process. A self-defined protocol is proposed to reduce the power consumption, and minimize the size of the tag. The specialized SOC reader system consists of the RF transceiver, digital baseband, MCU and host interface. Its power consumption is about 500 mW. Measurement results show that the system's reading range is 2 mm with 20 dBm reader output power. With an inductive antenna printed on a paper substrate around the OCA tag, the reading range can be extended from several centimeters to meters, depending on the shape and size of the inductive antenna.

    The measurement of endogenous allergens is required by the European Commission (EC) as part of the compositional analysis for GM products from host plants that are common causes of food allergy, such as soybean (EC Implementing Regulation No. 503/2013). In each case, the EC Implementing Regulation indicates that analysis be conducted on identified allergens as specified in the Organization of Economic Cooperation and Development (OECD) consensus documents on compositional considerations for new plant varieties. This communication discusses the methods available to measure endogenous allergens as well as the endogenous soybean allergens that should be analyzed. It is suggested herein that in conjunction with the 2012 OECD consensus document on soybean, any list of soybean allergens should be based on clinically relevant data among publicly available allergen databases and peer-reviewed scientific publications, and the ability to measure the identified allergen. Based on a detailed analysis of the scientific literature, the following key points are recommended: (1) the acceptance of serum-free, quantitative analytical method data as an alternative to traditional IgE reactivity qualitative or semi-quantitative data for evaluation of endogenous soybean allergen content; (2) eight of the 15 potential allergens listed in the OECD soybean consensus document (Gly m 3, Gly m 4, Gly m Bd28K, Gly m Bd30K, Gly m 5, Gly m 6, Gly m 8, and Kunitz trypsin inhibitor) have both appropriate supporting clinical data and sufficient sequence information to be evaluated in comparative endogenous soybean allergen studies; and (3) the remaining seven proteins (Gly m 1, Gly m 2, unknown 50kDa protein, unknown 39kDa protein, P-22-25, lipoxygenase and lectin) lack sufficient data for clear classification as confirmed allergens and/or available sequence information and should not be currently included in the measurement of endogenous soybean allergens in the compositional analysis for the EU

    The main aim of the present study is to investigate the short-term cognitive effects of computer games in children with different psychiatric disorders and normal controls. One hundred one children are recruited for the study (aged between 9 and 12 years). All participants played a motor-racing game on the computer for 1 hour. The TBAG form of the Stroop task was administered to all participants twice, before playing and immediately after playing the game. Participants with improved posttest scores, compared to their pretest scores, used the computer on average 0.67 +/- 1.1 hr/day, while the average administered was measured at 1.6 +/- 1.4 hr/day and 1.3 +/- 0.9 hr/day computer use for participants with worse or unaltered scores, respectively. According to the regression model, male gender, younger ages, duration of daily computer use, and ADHD inattention type were found to be independent risk factors for worsened posttest scores. Time spent playing computer games can exert a short-term effect on attention as measured by the Stroop test.

    Pseudomonas species are well recognized as dairy product spoilage organisms, particularly due to their ability to grow at refrigeration temperatures. Although Pseudomonas-related spoilage usually manifests itself in flavor, odor, and texture defects, which are typically due to production of bacterial enzymes, Pseudomonas is also reported to cause color defects. Because of consumer complaints, a commercial dairy company shipped 4 samples of high temperature, short time (HTST)-pasteurized milk with distinctly gray colors to our laboratory. Bacterial isolates from all 4 samples were identified as Pseudomonas azotoformans. All isolates shared the same partial 16S rDNA sequence and showed black pigmentation on Dichloran Rose Bengal Chloramphenicol agar. Inoculation of one pigment-producing P. azotoformans isolate into HTST-pasteurized fluid milk led to development of gray milk after 14 d of storage at 6°C, but only in containers that had half of the total volume filled with milk (∼500 mL of milk in ∼1,000-mL bottles). We conclusively demonstrate that Pseudomonas can cause a color defect in fluid milk that manifests in gray discoloration, adding to the palette of color defects known to be caused by Pseudomonas. This information is of considerable interest to the dairy industry, because dairy processors and others may not typically associate black or gray colors in fluid milk with the presence of microbial contaminants but rather with product tampering (e.g., addition of ink) or other inadvertent chemical contamination.

    Objective This study tested a pathway whereby acupuncturists’ communication of optimism for treatment effectiveness would enhance patients’ satisfaction during treatment, which in turn would contribute to better pain and function outcomes for patients with osteoarthritis of the knee. Methods Secondary analysis from a 2 arm (real vs. sham acupuncture, high vs. neutral expectations) RCT. 311 patients with knee osteoarthritis received acupuncture over 10–12 sessions. Coders rated the degree to which acupuncturists communicated optimism for the treatment’s effectiveness. Satisfaction with acupuncture was assessed 4 weeks into treatment. Pain and function were assessed 6 weeks following treatment. Results Patients experiencing better outcomes were more satisfied with acupuncture during treatment, were younger, and had better baseline pain and function scores. Satisfaction during treatment was greater when patients interacted with more optimistic clinicians and had higher pretreatment expectations for acupuncture efficacy. Conclusion Acupuncturists’ communication of optimism about treatment effectiveness contributed to pain and function outcomes indirectly through its effect on satisfaction during treatment. Future research should model pathways through which clinician-patient communication affects mediating variables that in turn lead to improved health outcomes. Practical Implications While clinicians should not mislead patients, communicating hope and optimism for treatment effectiveness has therapeutic value for patients. PMID:22857778

    Biomarkers that identify prepathological disease could enhance preventive management, improve animal health and productivity, and reduce costs. Circulating extracellular vesicles, particularly exosomes, are considered to be long-distance, intercellular communication systems in human medicine. Exosomes provide tissue-specific messages of functional state and can alter the cellular activity of recipient tissues through their protein and microRNA content. We hypothesized that exosomes circulating in the blood of cows during early lactation would contain proteins representative of the metabolic state of important tissues, such as liver, which play integral roles in regulating the physiology of cows postpartum. From a total of 150 cows of known metabolic phenotype, 10 cows were selected with high (n=5; high risk) and low (n=5; low risk) concentrations of nonesterified fatty acids, β-hydroxybutyrate, and liver triacylglycerol during wk 1 and 2 after calving. Exosomes were extracted from blood on the day of calving (d 0) and postcalving at wk 1 and wk 4, and their protein composition was determined by mass spectroscopy. Extracellular vesicle protein concentration and the number of exosome vesicles were not affected by risk category; however, the exosome protein cargo differed between the groups, with proteins at each time point identified as being unique to the high- and low-risk groups. The proteins α-2 macroglobulin, fibrinogen, and oncoprotein-induced transcript 3 were unique to the high-risk cows on d 0 and have been associated with metabolic syndrome and liver function in humans. Their presence may indicate a more severe inflammatory state and a greater degree of liver dysfunction in the high-risk cows than in the low-risk cows, consistent with the high-risk cows' greater plasma β-hydroxybutyrate and liver triacylglycerol concentrations. The commonly shared proteins and those unique to the low-risk category indicate a role for exosomes in immune function. The data

    The Picture Exchange Communication System (PECS) is a common treatment choice for non-verbal children with autism. However, little empirical evidence is available on the usefulness of PECS in treating social-communication impairments in autism. To test the effects of PECS on social-communicative skills in children with autism, concurrently taking into account standardized psychometric data, standardized functional assessment of adaptive behaviour, and information on social-communicative variables coded in an unstructured setting. Eighteen preschool children (mean age = 38.78 months) were assigned to two intervention approaches, i.e. PECS and Conventional Language Therapy (CLT). Both PECS (Phases I-IV) and CLT were delivered three times per week, in 30-min sessions, for 6 months. Outcome measures were the following: Autism Diagnostic Observation Schedule (ADOS) domain scores for Communication and Reciprocal Social Interaction; Language and Personal-Social subscales of the Griffiths' Mental Developmental Scales (GMDS); Communication and Social Abilities domains of the Vineland Adaptive Behavior Scales (VABS); and several social-communicative variables coded in an unstructured setting. Results demonstrated that the two groups did not differ at Time 1 (pre-treatment assessment), whereas at Time 2 (post-test) the PECS group showed a significant improvement with respect to the CLT group on the VABS social domain score and on almost all the social-communicative abilities coded in the unstructured setting (i.e. joint attention, request, initiation, cooperative play, but not eye contact). These findings showed that PECS intervention (Phases I-IV) can improve social-communicative skills in children with autism. This improvement is especially evident in standardized measures of adaptive behaviour and measures derived from the observation of children in an unstructured setting. © 2012 Royal College of Speech and Language Therapists.

    The objective of this study was to determine the increase in milk production from supplementation that occurred after supplementation ceased. This portion of the total response (i.e., the deferred response), although accepted, is generally not accounted for in short-term component research projects, but it is important in determining the economic impact of supplementary feeding. Fifty-nine multiparous Holstein-Friesian dairy cows were offered a generous allowance of spring pasture [>45 kg of dry matter (DM)/cow per day) and were supplemented with 0, 3, or 6 kg (DM)/d of pelleted concentrate (half of the allowance at each milking event) in a complete randomized design. Treatments were imposed for the first 12 wk of lactation. Treatments were balanced for cow age (5.4 ± 1.68 yr), calving date (July 27 ± 26.0 d), and genetic merit for milk component yield. During the period of supplementation, milk yield and the yield of milk components increased (1.19 kg of milk, 0.032 kg of fat, 0.048 kg of protein, and 0.058 kg of lactose/kg of concentrate DM consumed), but neither body condition score nor body weight was affected. After concentrate supplementation ceased and cows returned to a common diet of fresh pasture, milk and milk component yields remained greater for 3 wk in the cows previously supplemented. During this 3-wk period, cows that previously received 3 and 6 kg of concentrate DM per day produced an additional 2.3 and 4.5 kg of milk/d, 0.10 and 0.14 kg of fat/d, 0.10 and 0.14 kg of protein/d, and 0.10 and 0.19 kg of lactose/d, respectively, relative to unsupplemented cows. This is equivalent to an additional 0.19 kg of milk, 0.006 kg of fat, 0.006 kg of protein, and 0.008 kg of lactose per 1 kg of concentrate DM previously consumed, which would not be accounted for in the immediate response. As a result of this deferred response to supplements, the total milk production benefit to concentrate supplements is between 7% (lactose yield) and 32% (fat yield) greater

    Hauling is a critical part of the commercial milk supply chain, yet very few studies have aimed to understand its effect on raw milk quality. This study focused on the effect of extended-duration tanker use during hauling on raw milk quality at a commercial facility. Standard tanker use [cleaned-in-place (CIP) once per 24h] served as a control and an incremental between-load water rinse with sanitizer treatment (RS) was evaluated to mitigate any effect from extended duration hauling. During this study, 1 commercial truck with 2 trailers was monitored for 10d. The truck collected milk at a large dairy farm, transported the milk to a manufacturing facility, and then returned to the same farm for a second load. Each round-trip journey took between 10 and 12h, allowing for 2 loads per 24-h use period. Following the second delivery, the truck was cleaned by CIP treatment starting a new treatment day. Producer samples were collected from the raw milk bulk tank on the farm before loading milk into the tanker. The same milk was sampled directly out of the tanker truck before unloading at the manufacturer. Effect on individual bacteria count, thermophilic spore count, and preliminary incubation count was quantified through common industry tests. Surface sponge swabs were also used to monitor tanker sanitation and the efficacy of cleaning treatments. Results did not identify a negative effect on raw milk quality due to extended duration hauling. Whereas the addition of RS did not provide any measurable quality benefits for the microbial milk quality, swab results demonstrated that the RS treatment was able to reduce surface bacteria in the tanker, although not to the same level as the full CIP treatment. Based on this study, current CIP practices for long distance milk hauling appear to be effective in mitigating any measurable effect on raw milk quality.

  18. Short communication: Efficacy of copper sulfate hoof baths against digital dermatitis--Where is the evidence?

    Thomsen, Peter T

    2015-04-01

    Digital dermatitis is a major problem in modern dairy production because of decreased animal welfare and financial losses. Individual cow treatments are often seen as too time consuming by farmers, and walk-through hoof baths have therefore been used extensively to control digital dermatitis. For decades, copper sulfate hoof baths have been used to treat and prevent digital dermatitis. Copper sulfate has been referred to as the industry gold standard when it comes to hoof-bath chemicals. In several scientific studies testing the efficacy of other hoof-care products, copper sulfate has been used as a positive control, thereby indicating that copper sulfate has a known positive effect. However, this may not be the case. A dilemma may exist between (1) copper sulfate generally being perceived as being effective against digital dermatitis and (2) a possible lack of well-documented scientific evidence of this effect. The objective of this study was to evaluate the existing scientific literature to determine whether the efficacy of copper sulfate used in hoof baths against digital dermatitis has in fact been demonstrated scientifically. A systematic literature search identified 7 peer-reviewed journal articles describing the efficacy of copper sulfate in hoof baths as treatment or prevention of bovine digital dermatitis. Only 2 of the 7 studies compared copper sulfate to a negative control; most studies were relatively small, and often no clear positive effect of copper sulfate was demonstrated. In conclusion, the frequent claim that copper sulfate is widely reported to be effective is supported by little scientific evidence. Well-designed clinical trials evaluating the effect of copper sulfate against digital dermatitis compared with a negative control are needed. Until such studies have been made, the efficacy of copper sulfate in hoof baths against digital dermatitis remains largely unproven. Copyright © 2015 American Dairy Science Association.

  19. Effective quantum theories with short- and long-range forces

    International Nuclear Information System (INIS)

    Koenig, Sebastian

    2013-01-01

    At low energies, nonrelativistic quantum systems are essentially governed by their wave functions at large distances. For this reason, it is possible to describe a wide range of phenomena with short- or even finite-range interactions. In this thesis, we discuss several topics in connection with such an effective description and consider, in particular, modifications introduced by the presence of additional long-range potentials. In the first part we derive general results for the mass (binding energy) shift of bound states with angular momentum L ≥ 1 in a periodic cubic box in two and three spatial dimensions. Our results have applications to lattice simulations of hadronic molecules, halo nuclei, and Feshbach molecules. The sign of the mass shift can be related to the symmetry properties of the state under consideration. We verify our analytical results with explicit numerical calculations. Moreover, we discuss the case of twisted boundary conditions that arise when one considers moving bound states in finite boxes. The corresponding finite-volume shifts in the binding energies play an important role in the study of composite-particle scattering on the lattice, where they give rise to topological correction factors. While the above results are derived under the assumption of a pure finite-range interaction - and are still true up to exponentially small correction in the short-range case - in the second part we consider primarily systems of charged particles, where the Coulomb force determines the long-range part of the potential. In quantum systems with short-range interactions, causality imposes nontrivial constraints on low-energy scattering parameters. We investigate these causality constraints for systems where a long-range Coulomb potential is present in addition to a short-range interaction. The main result is an upper bound for the Coulomb-modified effective range parameter. We discuss the implications of this bound to the effective feld theory (EFT) for

    Using responses to questionnaires and results of saliva samples from 40 women, the authors assessed the effects on health of participation in a short leisure trip (2 nights, 3 d) to Kyushu Island in Japan. They addressed transportation, sightseeing, and group activities during the tour, which might differ from participants' usual activities. Levels of the salivary endocrinological stress markers cortisol and chromogranin A (CgA) were determined by enzyme-linked immunosorbent assay (ELISA). In each of the groups with characteristics considered healthy and related to lifestyle, patterns of behavior, perceived stressors, and stress reactions, a decrease in the cortisol levels and an increase in the CgA levels were apparent during the tour. The baseline for stress hormone changes was the levels on awakening on Day 1 (i.e., immediately before the tour). These findings suggest that even short periods of travel can bring about a reduction in di-stress and acquisition of eu-stress, experienced as feeling uplifted or fulfilled.

    The digital revolution affects the environment on several levels. Most directly, information and communications technology (ICT) has environmental impacts through the manufacturing, operation and disposal of devices and network equipment, but it also provides ways to mitigate energy use, for example through smart buildings and teleworking. At a broader system level, ICTs influence economic growth and bring about technological and societal change. Managing the direct impacts of ICTs is more complex than just producing efficient devices, owing to the energetically expensive manufacturing process, and the increasing proliferation of devices needs to be taken into account. © 2011 Macmillan Publishers Limited.

    Full Text Available The paper is intended to raise awareness of some recurrent problems related to cultural and linguistic security in translation alongside strategies of achieving it. Globalisation means global thinking, individual accountability and the development of new sensitivities and capabilities. Different models of Intercultural Communicative Competence are scrutinised in an attempt to identify a common core of generalisable traits, which could be further applied to a wide range of translation situations. The (intercultural load is of paramount importance in translation being, more often than not, the cause of serious misunderstanding if the translator does not adequately equate the two cultures or bridge the cultural gap.

    Barren tip on corn ear is an important agronomic trait in maize, which is highly associated with grain yield. Understanding the genetic basis of tip-barrenness may help to reduce the ear tip-barrenness in breeding programs. In this study, ear tip-barrenness was evaluated in two environments in a F2:3 population, and it showed significant genotypic variation for ear tip-barrenness in both environments. Using mixed-model composite interval mapping method, three additive effects quantitative trait loci (QTL) for ear tip-barrenness were mapped on chromosomes 2, 3 and 6, respectively. They explained 16.6% of the phenotypic variation, and no significant QTL × Environment interactions and digenic interactions were detected. The results indicated that additive effect was the main genetic basis for ear tip-barrenness in maize. This is the first report of QTL mapped for ear tip-barrenness in maize. (Author)

    Full Text Available Oxfendazole is recommended as the drug of choice for treating porcine cysticercosis. The drug does not kill brain cysts and is not registered for use in pigs. Latest its safety in the recommended dose has been questioned. The aim of this study was to investigate two alternative anthelminthics. The efficacy of praziquantel and ivermectin was compared to oxfendazole In Vitro on Taenia solium. Cysts of T. solium were isolated from infected pork and incubated in culture media together with the drugs. The degree of evagination was used as effect measurement and determined after 6 hours. Praziquantel had a half maximal effective concentration (EC50 of value 0.006 ± 0.001 μg/mL. Ivermectin did not show any impact on the evagination in concentrations from 0.001 to 30 μg/mL and neither did oxfendazole in concentrations from 0.001 to 50 μg/mL.

    2009-01-01

    Pregabalin is a newly developed synthetic gamma-aminobutyric acid (GABA) that is approved for the treatment of fibromyalgia and several neuropathy. It has been proven to show analgesic, anxiolytic, anticonvulsant and sleep enhancement effects, which could be applicable in the treatment of a variety of psychiatric disorders. There have been consistent reports that unexplained somatic symptoms (i.e., pain) may be a part of psychiatric disorders such as major depressive disorder (MDD) and anxiety disorders. Previous researches have also suggested the possible therapeutic potential of anticonvulsants as augmentation therapy or monotherapy in the treatment of mood disorders and anxiety disorders. Hence this short perspective tries to prompt and facilitate a shifting of researchers' attention to potential neuropsychotropic drug role of pregabalin to treat a wide range of neuropsychiatric disorders.

    Lyophilization is considered an effective way to preserve the activity of milk starters, such as lactic acid bacteria, in which proper protective agents play key roles. In this study, Lactobacillus casei Zhang, a probiotic bacterium applied as a milk starter in China, was used to investigate the effects of various cryoprotectants according to cell survival rate and physiological characteristics. The result showed a significant survival improvement to 86.6% when glutathione (GSH) was added as an ideal cryoprotectant. Further study revealed that GSH plays a key role on maintaining higher unsaturation ratio of cell membrane and shorter chain length of saturated fatty acids. In this case, the intact cell structure can be obtained. These findings will contribute not only to deepen the understanding of cells during lyophilization but also to improve the industrial performance of certain milk starters such as L. casei Zhang by application of GSH as cryoprotectant.

    In liver hepatocytes, the HFE gene regulates cellular and systemic iron homeostasis by modulating cellular iron-uptake and producing the iron-hormone hepcidin in response to systemic iron elevation. However, the mechanism of iron-sensing in hepatocytes remain enigmatic. Therefore, to study the effect of iron on HFE and hepcidin (HAMP) expressions under distinct extracellular and intracellular iron-loading, we examined the effect of holotransferrin treatment (1, 2, 5 and 8 g/L for 6 h) on intracellular iron levels, and mRNA expressions of HFE and HAMP in wild-type HepG2 and previously characterized iron-loaded recombinant-TfR1 HepG2 cells. Gene expression was analyzed by real-time PCR and intracellular iron was measured by ferrozine assay. Data showed that in the wild-type cells, where intracellular iron content remained unchanged, HFE expression remained unaltered at low holotransferrin treatments but was upregulated upon 5 g/L (p HFE and HAMP expressions were elevated only at low 1 g/L treatment (p HFE (p HFE mRNA was independently elevated by extracellular and intracellular iron-excess. Thus, it may be involved in sensing both, extracellular and intracellular iron. Repression of HAMP expression under simultaneous intracellular and extracellular iron-loading resembles non-hereditary iron-excess pathologies.

    Full Text Available The aim of this study was to estimate the coefficients of heritability and genetic correlations among visual scores (conformation, CPW; precocity, PPW; musculature, MPW and reproductive traits: age at first lambing (AFL and scrotal circumference (SC evaluated at 180 days of age in Suffolk lambs. In the statistical model only the additive genetic effect was considered as random effect. The heritability estimates by univariate analyses for CPW, PPW, MPW, AFL and SC were 0.08, 0.12, 0.09, 0.20 and 0.22, respectively. The genetic correlations among AFL and CPW, PPW, MPW were -0.26, 0.19, and 0.08, respectively. The genetic correlation among SC and CPW, PPW, MPW were, respectively, 0.54, 0.88 and 0.86, and between AFL and SC was 0.26. The direct selection for conformation, precocity and musculature at 180 days of age and age at first lambing will provide slow genetic progress due to low heritability estimates. It is possible to obtain genetic gain in sexual precocity through selection on scrotal circumference in Suffolk rams. The favorable genetic correlation among visual scores and SC and between CPW and AFL, indicated the possibility to gain in genetic progress for reproductive traits through indirect selection of the visual scores in Suffolk sheep.

In previous studies, curcumin has been shown to have anticancer, antioxidant, and anti-inflammatory effects. In this study, the cytotoxicity of different concentrations (5, 10, 25, 50, 75, and 100 µM of curcumin dissolved in dimethyl sulfoxide was compared between MG-63 osteosarcoma and healthy human osteoblast cells. Consequently, the viability of osteosarcoma cells was less than 50% at a concentration of 10 µM compared to the control sample without curcumin, but healthy osteoblast cells had at least 80% viability throughout all the concentrations tested. The results demonstrated that MG-63 osteosarcoma cells were much more sensitive in terms of cytotoxicity to curcumin, while the healthy human osteoblasts exhibited a higher healthy viability after 24 hours of curcumin treatment. Therefore, this study showed that at the right concentrations (5 µM to 25 µM, curcumin, along with a proper nanoparticle drug delivery carrier, may selectively kill bone cancer cells over healthy bone cells.Keywords: curcumin, osteosarcoma, human osteoblast, viability, bone cancer

    The domestication of the Equus genus 5000-6000 years ago has influenced the history of human civilization. As soon as horse and donkey species had been domesticated, they were crossbred, producing humanity's first documented attempt at animal genome manipulation. Since then, the mule (male donkey x female horse) and the reciprocal cross (the hinny, male horse x female donkey) have been the most common equine hybrids in the world. Due to their hybrid vigor, mules and hinnies have been intensively used for carrying loads and people and for tilling the land. Despite their importance, visual distinction of mules and hinnies is difficult due to high phenotypic resemblance. However, the distinction between these two hybrids is of pivotal importance for equid breeders and ranchers. In this study, an easy, low-cost, effective, and fast multiplex-polymerase chain reaction method was developed to distinguish the maternal origin of mules and hinnies, targeting the hyper-variable mitochondrial DNA D-loop region. This methodology can help breeders, ranchers, animal science professionals, and researchers manage their equine herds with more confidence and precision.

    There has been an explosion of knowledge in geotechnical engineering, yet the art and science paradigm remains deeply rooted in the field. Geotechnical engineering students will face today’s prevailing difficulties as well as new and demanding geotechnical challenges such as those associated with energy and the environment. Confronting these situations and needs requires a sound and resourceful foundation. Therefore, geotechnical engineering teachers must review their educational programmes (a) to reconsider the role of empiricism, (b) to prune incorrect concepts and biases (e.g., enduring misnomers, incorrect explanations, superseded graphical approaches, unsound tricks and fragile correlations, and education based on extremes (dry–saturated, clay–sand, drained–undrained)), and (c) to promote a careful understanding of fundamentals (e.g., the particulate nature of soils and fractured rocks, formation history, the essential relevance of effective stress, thermo-hydro-chemo-mechanical coupled processes, repetitive loads and ubiquitous localisations). Finally, they must continue reflecting on the role of the engineer in society, within an ever-changing world as the driver for innovation.

    Despite the increasing knowledge of prevention and control strategies, bovine mastitis remains one of the most challenging diseases in the dairy industry. This study investigated the antimicrobial activity of 13 species of lactic acid bacteria (LAB), previously isolated from the honey crop of the honeybee, on several mastitis pathogens. The viable LAB were first reintroduced into a sterilized heather honey matrix. More than 20 different bovine mastitis isolates were tested against the mixture of the 13 LAB species in the honey medium using a dual-culture overlay assay. The mastitis isolates were identified through bacteriological culturing, followed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Additionally, the mastitis isolates were subjected to antimicrobial susceptibility testing through disk diffusion. Growth of all tested mastitis pathogens, including the ones displaying antimicrobial resistance to one or more antimicrobial compounds, were inhibited to some extent by the honey and LAB combination. The antibacterial effect of these LAB opens up new perspectives on alternative treatment and prevention of bovine mastitis. Copyright © 2016 American Dairy Science Association.

    The amount of the major macro elements required to produce a given crop has been determined for a set of 11 almond (Prunus amygdalus Batsch) cultivars growing in the Middle Ebro Valley (NE Spain). A wide diversity of nutrient exports was found among the different cultivars. Although the production of kernels is the main objective when growing almonds, all the different fruit components: the mesocarp (hull), the endocarp (shell) and the seed (kernel), were taken into account. The different fruit components showed a great variation among cultivars, and the amount of fruit dry matter required for producing 1 kg of kernel ranged from 4.32 kg in Guara to 10.56 kg in Desmayo Largueta. Similarly, the macroelement requirements to produce a given amount of kernels varied among the different cultivars. Guara has proved to be the most effective cultivar in taking advantage of the mineral elements for producing a crop, showing that this efficiency is independent of the shell type. (Author) 9 refs.

    Neutrophil gelatinase-associated lipocalin (NGAL) is a neutrophil-derived protein whose concentration increases in plasma and urine with ongoing renal damage. Urinary leucocytes can be a potential source of urinary NGAL. The aim of this study is to investigate the effects of urinary neutrophil count and other urinary parameters on urinary NGAL values in urine with negative culture. Urinalysis, urine culture, and determination of urinary NGAL were performed on 33 clinically healthy nonproteinuric dogs with negative urinoculture. The median uNGAL concentration in dogs in this study population was 9.74 ng/mL (IQR 1.93-25.43 ng/mL). In samples with WBCs > 5 hpf (mean 15.9, 6-50 leucocytes/hpf), median uNGAL value was significantly higher than that in samples with WBCs dogs with negative urinoculture. The present study suggests that noninfectious pyuria is significantly correlated with urinary NGAL values and might influence uNGAL values.

    The objective of the experiment was to compare the use of a PGF2α analogue (Cloprostenol) IM, with an intravaginal progestagen sponge, flurogestone acetate (FGA), and equine chorionic gonadotropin (eCG) IM application protocol. A total of 30 cyclical hair ewes (54.07 ± 0.5 kg live weight, body condition score 3.5 ± 0.5, and age 3 ± 1 years) were used. For the control group ewes (n = 15), intravaginal sponges (IS) impregnated with 20 mg of FGA were inserted for 12 days with 500 IU of eCG IM at sponges withdrawal. For the PG group ewes (Treatment group n = 15), two injections of Cloprostenol (75 mcg) were given 12 days apart. The presence of estrus was detected using two rams with 8 h interval beginning at the end of the treatment. Progesterone concentrations in blood were measured by solid phase radioimmunoassay. A student's t test was performed to analyze the duration of estrus and the interval between the ends of the treatment and the onset of estrus (ET-OE) presentation. Progesterone levels were compared with two-way ANOVA, with treatment, and day of menstrual cycle as fixed factors. Treatment costs ratio was calculated by dividing the total costs of FGA IS application between total costs of Cloprostenol application. Significant differences (P Progesterone levels in both treatments. Treatment costs of Cloprostenol protocol were 2.63 cheaper than FGA including disposable material, biological products, and labor. It was concluded that Cloprostenol could be an effective tool in estrus synchronization in hair sheep in tropical areas.

    Replacement decisions have a major effect on dairy farm profitability. Dynamic programming (DP) has been widely studied to find the optimal replacement policies in dairy cattle. However, DP models are computationally intensive and might not be practical for daily decision making. Hence, the ability of applying machine learning on a prerun DP model to provide fast and accurate predictions of nonlinear and intercorrelated variables makes it an ideal methodology. Milk class (1 to 5), lactation number (1 to 9), month in milk (1 to 20), and month of pregnancy (0 to 9) were used to describe all cows in a herd in a DP model. Twenty-seven scenarios based on all combinations of 3 levels (base, 20% above, and 20% below) of milk production, milk price, and replacement cost were solved with the DP model, resulting in a data set of 122,716 records, each with a calculated retention pay-off (RPO). Then, a machine learning model tree algorithm was used to mimic the evaluated RPO with DP. The correlation coefficient factor was used to observe the concordance of RPO evaluated by DP and RPO predicted by the model tree. The obtained correlation coefficient was 0.991, with a corresponding value of 0.11 for relative absolute error. At least 100 instances were required per model constraint, resulting in 204 total equations (models). When these models were used for binary classification of positive and negative RPO, error rates were 1% false negatives and 9% false positives. Applying this trained model from simulated data for prediction of RPO for 102 actual replacement records from the University of Wisconsin-Madison dairy herd resulted in a 0.994 correlation with 0.10 relative absolute error rate. Overall results showed that model tree has a potential to be used in conjunction with DP to assist farmers in their replacement decisions. Copyright © 2014 American Dairy Science Association.

    Perfluoroalkyl substances (PFAS) are fully fluorinated compounds widely used during the last 60 yr in the production of multiple industrial and consumer applications, such as food packaging, nonstick cookware, cleaning agents, and many more. These emerging contaminants have recently become of concern for human health because of their potential negative effects. The risk of exposure to PFAS for humans is mainly related to diet, and the increasing interest in food safety has led the European Commission to call Member States to monitor these contaminants in food matrices. The purpose of the present work was to perform the first monitoring on the presence of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), the 2 main and most widely investigated molecules of this family, in cow milk commercially available in Italy. We used an analytical protocol consisting of liquid-liquid extraction followed by 2 purification steps through solid-phase extraction cartridges and injection on an ultra-performance liquid chromatography-tandem mass spectroscopy system. The analysis of 67 samples of different types of cow milk from Italy demonstrated that contamination by PFOS was often present, although at relatively low concentrations (up to 97 ng/L), whereas PFOA was rarely found. On the basis of these results and data reported in the literature on this matrix, milk does not seem to be a major source of PFAS compared with other food categories such as fish and seafood. However, variability among different types of milk must be taken into account, and surveys of milk-derived products would be helpful to better define the risk for consumers.

    An experiment was conducted to compare bacterial counts of mastitis pathogens in deep-packed manure solids bedding with those in manure solids bedding replaced daily from mattresses. Eighteen Holstein cows were housed in 1 pen with 18 stalls. One row of 9 stalls was equipped with mattresses topped with bedding. The back one-third of these stalls toward the alleyway was covered in 25 mm of recycled manure solids, which was removed daily for the next 6 d and replaced with bedding from the brisket board and lunge space areas of stalls. The second row of 9 stalls was bedded for 3 wk with 100 to 150 mm of deep-pack recycled manure bedding from which only fecal matter was removed daily. After 3 wk, bedding treatments were changed between rows in a switchback design. Mean total gram-negative bacterial counts did not differ between treatments throughout the experiment. Coliform and Klebsiella spp. bacterial counts were lower in daily replaced bedding compared with deep pack across the experiment and on each of d 0, 1, 2, and 6. Streptococcal counts were reduced in daily replacement stalls compared with deep-pack stalls on d 0 and greater in daily replacement stalls compared with deep-pack stalls on d 1, 2, and 6. Daily replacement of recycled manure bedding from the back one-third of the stalls appeared to be an effective approach to reducing exposure to coliforms, specifically Klebsiella, but not streptococci. However, bacterial counts in bedding from both treatments were elevated throughout the trial and resulted in considerable risk for exposure to teats and development of intramammary infections.

    A well-managed colostrum program on farms is the most important step in reducing disease in neonatal calves. In the last few years, colostrum replacers have increased in popularity and are designed to be an alternative to colostrum on farms that have poor colostrum quality, limited colostrum reserves, or to break the cycle of transmission for certain infectious diseases. However, it is important to make sure these products are effective and are capable of providing adequate serum immunoglobulin concentrations. The objective of this study was to evaluate the efficacy of a commercially available colostrum replacer product in dairy calves. Holstein calves from a single dairy were randomly assigned to 1 of 3 groups at birth. Group 1 (n = 21) calves were given 4 quarts of colostrum via esophageal feeder within 3 h of birth and served as the control group for this study. Group 2 (n = 21) received 2 packages of a colostrum replacer product, and group 3 (n = 21) received 3 packages of the colostrum replacer product within 3 h of birth. Blood samples from all calves were collected 24 h after colostrum administration and analyzed for serum total protein and IgG concentrations. Calves fed fresh colostrum had significantly higher serum total protein levels and IgG concentrations compared with calves fed the colostrum replacer product. Calves fed the colostrum replacer also had a significantly higher percentage of calves with failure of passive transfer (serum IgG <1,000 mg/dL). The colostrum replacer product evaluated in this study failed to routinely provide adequate IgG concentrations when fed according to label directions.

    Full Text Available Worldwide cooperation between laboratories working with classical swine fever virus (CSFV requires exchange of virus isolates. For this purpose, shipment of CSFV RNA is a safe alternative to the exchange of infectious material. New techniques using desiccation have been developed to store RNA at room temperature and are reported as effective means of preserving RNA integrity. In this study, we evaluated the stability and integrity of dried CSFV RNA stored at room temperature. First, we determined the stability of CSFV RNA covering CSFV genome regions used typically for the detection of viral RNA in diagnostic samples by reverse transcription-polymerase chain reaction (RT-PCR. To this end, different concentrations of in vitro-transcribed RNAs of the 5’-untranslated region and of the NS5B gene were stored as dried RNA at 4, 20, and 37oC for two months. Aliquots were analyzed every week by CSFV-specific quantitative real-time RT-PCR. Neither the RNA concentration nor the storage temperature did affect CSFV RNA yields at any of the time evaluated until the end of the experiment. Furthermore, it was possible to recover infectious CSFV after transfection of SK-6 cells with dried viral RNA stored at room temperature for one week. The full-length E2 of CSFV was amplified from all the recovered viruses, and nucleotide sequence analysis revealed 100% identity with the corresponding sequence obtained from RNA of the original material. These results show that CSFV RNA stored as dried RNA at room temperature is stable, maintaining its integrity for downstream analyses and applications.

    Our aim was to assess the effect of pasteurization temperature on inactivation of staphylococcal enterotoxins (SE). Milk samples were inoculated with log 4.38 to 5.18cfu/mL of 40 different Staphylococcus aureus strains having the ability to produce types A, B, or C SE and incubated at 37°C for 24h to develop SE. This incubation was followed by heat treatment for 15 s at 72, 85, and 92°C. Samples were analyzed for Staph. aureus count by plate method and, specifically, for SE presence. An enzyme-linked immunofluorescent assay on a MiniVIDAS analyzer (bioMérieux, Marcy l'Étoile, France) was used to detect SE, which were determined semiquantitatively based on test values. The Staph. aureus count in milk before pasteurization did not affect the amount of SE. Before pasteurization, SEB was detected in the lowest amount compared with other SE types. Staphylococcal enterotoxins were markedly reduced with pasteurization and inactivated at pasteurization temperatures to an extent depending on the amount in the sample before pasteurization. After pasteurization at 72°C, SE were detected in 87.5% of samples (35/40), after pasteurization at 85°C in 52.5% of samples (21/40), and after pasteurization at 92°C in 45.0% of samples (18/40). We determined that SE may still persist in milk even when Staph. aureus bacteria are inactivated through pasteurization. Although pasteurization may partially inactivate SE in milk, a key measure in the prevention of staphylococcal enterotoxicosis linked to pasteurized milk consumption is to avoid any cold chain disruption during milk production and processing.

    To conduct a systematic review of the literature to identify, describe and assess interventions of information and communication technology on the processes of communication and associated patient outcomes within hospital settings. Studies published from the years 1996 to 2010 were considered and were selected if they described an evaluation of information and communication technology interventions to improve clinical communication within hospitals. Two authors abstracted data from full text articles, and the quality of individual articles were appraised. Results of interventions were summarized by their effect. There were 18 identified studies that evaluated the use of interventions that included alphanumeric paging, hands-free communication devices, mobile phones, smartphones, task management systems and a display based paging system. Most quantitative studies used a before and after study design and were of lower quality. Of all the studies, there was only one prospective randomized study, but this study used only simulated communication events. Quantitative studies identified improved perceptions of communication and some improvement in communication metrics. Qualitative studies described improvements in efficiency of communication but also issues of loss of control and reliability. Despite the rapid advancement in information and communications technology over the last decade, there is limited evidence suggesting improvements in the ability of health professionals to communicate effectively. Given the critical nature of communication, we advocate further evaluation of information and communication technology designed to improve communication between clinicians. Outcome measures should include measures of patient-oriented outcomes and efficiency for clinicians. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Several factors affect the success of students in college classes. The objective of this research was to determine what factors affect success of undergraduate students in an anatomy and physiology class. Data were collected from 602 students enrolled in the Agriculture and Life Sciences (ALS) 2304 Animal Physiology and Anatomy course from 2005 through 2012. The data set included 476 females (79.1%) and 126 males (20.9%). Time to complete exams was recorded for each student. For statistical analyses, students' majors were animal and poultry sciences (APSC), agricultural sciences, biochemistry, biological sciences, dairy science, and "other," which combined all other majors. All analyses were completed using the GLIMMIX procedure of SAS (SAS Institute Inc., Cary, NC). Gender, major, matriculation year, major by year interaction, gender by year interaction, and time to complete the exam affected final course grade. The significant gender effect was manifested in the final grade percentage of 75.9 ± 0.4 for female students compared with 72.3 ± 0.6 for male students. Junior males had final course grades comparable with those of females, but sophomore and senior males had lower final course grades than other combinations. Biology majors had a final grade of 82.4 ± 0.6 and this grade was greater than all other majors. Students classified as "other" had a final score of 74.4 ± 0.8, which was greater than agricultural science majors (69.5 ± 0.9). The APSC grade (72.6 ± 0.5) was higher than the agricultural science majors. Junior students had significantly greater final grades (76.1 ± 0.5) than sophomores (73.3 ± 0.6) and seniors (72.9 ± 0.9). All biology students had greater final grades than all other majors, but biochemistry juniors had greater final course grades than APSC, agricultural science, and dairy science juniors. "Other" seniors had greater final course grades than agricultural science seniors. The regression for time to complete the exam was

    Mastitis remains a critical disease in the dairy industry and the use of intramammary antibiotics plays a critical role in mastitis treatment. Hetacillin is currently approved as an intramammary antibiotic that is used to treat mastitis in dairy cows. It is approved for once a day administration and can be used for a total of 3 d. An increasing number of dairy farms are milking 3 times per day (instead of the traditional 2 times per day) and very little pharmacokinetic data exists on the use of intramammary drugs in a 3×system. The primary purpose of this study was to determine if once a day intramammary infusion of hetacillin is sufficient to maintain therapeutic drug concentrations in cattle milked 3 times per day. Eight Holstein cattle milked 3 times per day were used in this study. After collecting a baseline milk sample, each cow received intramammary infusions of hetacillin in the left front and right rear quarters once a day for 3 d. Milk samples from each of the treated quarters were collected at each milking and frozen until analysis. Milk samples were analyzed for ampicillin concentrations using an ultra-performance liquid chromatography method. All treated quarters had antibiotic concentrations well above the minimum inhibitory concentration (MIC) for gram-positive mastitis pathogens at 8 and 16 h postinfusion. Milk concentrations had fallen well below the MIC by the 24-h period (before the next infusion). All 8 cows in this study consistently had individual quarter milk ampicillin concentrations below the FDA tolerance of 0.01 μg/mL (10 ppb) within 48 h of the last infusion. Based on this study, milk ampicillin concentrations exceed the minimum inhibitory concentration required to inhibit the growth of 90% of organisms (MIC90) for at least 65% of the dosing interval, which is sufficient for once-daily dosing with most cases of gram-positive mastitis. Therefore, intramammary hetacillin should be an effective treatment for the vast majority of gram

    The intestinal tract of the newborn is particularly sensitive to gastrointestinal disorders, such as infantile diarrhea or necrotizing colitis. Perinatal development of the gut also encompasses the maturation of the enteric nervous system (ENS), a main regulator of intestinal motility and barrier functions. It was recently shown that ENS maturation can be enhanced by nutritional factors to improve intestinal maturation. Bioactivity of milk proteins is often latent, requiring the release of bioactive peptides from inactive native proteins. Several casein-derived hydrolysates presenting immunomodulatory properties have been described recently. Furthermore, accumulating data indicate that milk-derived hydrolysate can enhance gut maturation and enrichment of milk formula with such hydrolysates has recently been proposed. However, the capability of milk-derived bioactive hydrolysate to target ENS maturation has not been analyzed so far. We, therefore, investigated the potential of a recently described tryptic β-casein hydrolysate to modulate ENS growth parameters in an in vitro model of rat primary culture of ENS. Rat primary cultures of ENS were incubated with a bioactive tryptic β-casein hydrolysate and compared with untreated controls or to cultures treated with native β-casein or a Prolyve β-casein hydrolysate (Lyven, Colombelles, France). Differentiation of enteric neurons and enteric glial cells, and establishment of enteric neural network were analyzed using immunohistochemistry and quantitative PCR. Effect of tryptic β-casein hydrolysate on bone morphogenetic proteins (BMP)/Smad pathway, an essential regulator of ENS development, was further assessed using quantitative PCR and immunochemistry. Tryptic β-casein hydrolysate stimulated neurite outgrowth and simultaneously modulated the formation of enteric ganglia-like structures, whereas native β-casein or Prolyve β-casein hydrolysate did not. Additionally, treatment with tryptic bioactive

    Smoke from plastics can cause immediate problems in electrical equipment in the form of shorting and increased leakage currents, as well as long-term corrosion (metal loss). The short-term problems can be especially serious for critical control instrumentation such as that found in nuclear reactors or telecommunications systems. The US Nuclear Regulatory Commission and Sandia National Laboratories are sponsoring a program to determine the modes and probabilities of digital equipment failure during exposure to smoke and up to 24 hours after the exposure. Early tests on computer systems have shown that the most common immediate problems are temporary and are likely to be caused by increased leakage currents. High-voltage circuits are especially vulnerable since the charged particles in smoke are drawn to those surfaces. To study failure probabilities, smoke exposure tests with real-time measurements will be carried out to determine how the electrical properties of the environment are affected by smoke concentration and content. Digital communication cable will be included in the tests because temporary shorts that cannot be detected through dc measurements may cause interruptions in communications between computers. The reaction of the equipment to changed electrical properties of the environment will be modeled. Equipment that can be used for testing and modeling is being solicited

    2012-01-01

    The purpose of this study was to examine the communication dynamics leading to the adoption of new attitudes and cognitions in health education sessions. We examined the verbal interactions at work in persuasive communication in 16 health education sessions. The study found that the medical expertise of the educator and the initial level of commitment of the participants had a positive effect on adherence to recommendations. However, persuasive communication in health education sessions appears to involve a paradoxical process in which criticism of the message can go hand in hand with the expression of an intention to implement new risk-reducing behaviors.

    The primary purpose of the project was to evaluate the effectiveness of two techniques for improving organizational communication: (1) an Automated Maintenance Management System (AMMS) and (2) Interdepartmental Coordination Meetings. Additional objectives concerned the preparation of functional requirements for an AMMS, and training modules to improve group communication skills. Four nuclear power plants participated in the evaluation. Two plants installed AMMSs, one plant instituted interdepartmental job coordination meetings, and the fourth plant served as a control for the evaluation. Questionnaires and interviews were used to collect evaluative data. The evaluation focused on five communication or information criteria: timeliness, redundancy, withholding or gatekeeping, feedback, and accuracy/amount

    2017-01-01

    Physics students graduate with a huge array of transferrable skills, which are extremely useful to employers (particularly in the private sector, which is the largest employment base of physicists at all degree levels). However, the key to successfully connecting with these opportunities lies in how well graduates are able to communicate their skills and abilities to potential employers. The ability to communicate effectively is a key professional skill that serves scientists in many contexts, including interviewing for jobs, applying for grants, or speaking with law and policy makers. In this interactive workshop, Crystal Bailey (Careers Program Manager at APS) and Gregory Mack (Government Relations Specialist at APS) will lead activities to help attendees achieve their goals through better communication. Topics will include writing an effective resume, interviewing for jobs, and communicating to different audiences including Congress, among others. Light refreshments will be served.

    Health workers' experiences and understanding of the myths, misconceptions, beliefs about TB, and patients in the community (and effective communication methods) can be useful in designing effective IEC materials and strategies. To study the perceptions and experiences of health workers regarding TB disease, patients, and effective communication strategies in TB control. A survey was conducted among health workers involved in Directly Observed Treatment Short (DOTS) course. Data regarding general health beliefs, prevalent myths and misconceptions about TB in their respective localities, knowledge level among patients, and utilization of various communication strategies were collected. There is a significant increase in knowledge about TB during DOTS among patients, as observed by about half of the health workers. TB patients are aware about how TB spreads to others and their responsibilities. Regular interaction with patients is required for treatment adherence. Two thirds of the health workers believe that media-mix strategy can be very effective in creating awareness among the patients as well as the public. Health workers realized that the video player facility on their mobile phones is useful for showing health-related videos. A combination of mass media and interpersonal communication could be effective for TB control. Face-to-face communication with community members, patient-provider discussions, and information through television could be very effective techniques. Exclusive communication materials should be designed for family members of the patients. Smart phones can be used for effective implementation of TB control programs.

    The aim of this study was to examine the longitudinal effects of communication styles on marital satisfaction and distress of parents of children treated for cancer. Marital dissatisfaction (Maudsley Marital Questionnaire), intimacy, avoidance, destructive and incongruent communication (Communication Skills Inventory) and psychological distress (General Health Questionnaire) were assessed in 115 parents of pediatric cancer patients shortly after diagnosis (T1) and 5 years later (T2). Only mothers' marital dissatisfaction increased significantly over time. No gender differences in dissatisfaction were found. Mothers had a significantly higher lack of intimacy score than fathers. All T1 communication styles were significantly univariately related to fathers' and mothers' T2 marital dissatisfaction, while not to T2 distress. Mothers' T1 marital dissatisfaction accounted for 67% and fathers' for 12% in the explained variance of T2 dissatisfaction. T1 destructive communication uniquely affected fathers' T2 marital dissatisfaction and T1 avoidant communication that of mothers. Five years after cancer diagnosis in their children, the quality of parents' marital relationships seemed largely unchanged. Parents' use of communication skills at diagnosis appeared to have limited effect on their marital dissatisfaction and no effect on their distress 5 years later. While avoidant communication seemed indicative of mothers' marital distress, fathers' seemed affected by destructive communication. Copyright © 2014 John Wiley & Sons, Ltd.

    Full Text Available Background: “Sleep-low” consists of a sequential periodization of carbohydrate (CHO availability—low glycogen recovery after “train high” glycogen-depleting interval training, followed by an overnight-fast and light intensity training (“train low” the following day. This strategy leads to an upregulation of several exercise-responsive signaling proteins, but the chronic effect on performance has received less attention. We investigated the effects of short-term exposure to this strategy on endurance performance. Methods: Following training familiarization, 11 trained cyclists were divided into two groups for a one-week intervention—one group implemented three cycles of periodized CHO intake to achieve the sleep-low strategy over six training sessions (SL, CHO intake: 6 g·kg−1·day−1, whereas the control group consumed an even distribution of CHO over the day (CON. Tests were a 2 h submaximal ride and a 20 km time trial. Results: SL improved their performance (mean: +3.2%; p < 0.05 compared to CON. The improvement was associated with a change in pacing strategy with higher power output during the second part of the test. No change in substrate utilization was observed after the training period for either group. Conclusion: Implementing the “sleep-low” strategy for one week improved performance by the same magnitude previously seen in a three-week intervention, without any significant changes in selected markers of metabolism.

    A single quantum well semiconductor laser based on wurtzite-nitride is designed and analyzed for short distance communication wavelength (at around 1300 nm). The laser structure has 12 Å well layer of InN, 15 Å barrier layer of In0.25Ga0.75N, and 54 Å separate confinement heterostructure layer of GaN. To calculate the electronic characteristics of the structure, a self-consistent method is used where Hamiltonian with effective mass approximation is solved for conduction band while six-bands Hamiltonian matrix with k · p formalism including the polarization effect, valence-band mixing effect, and strain effect is solved for valence band. The interband optical transition elements, optical gain, differential gain, radiative current density, spontaneous emission rate, and threshold characteristics have been calculated. The wave function overlap integral is found to be 45.93% for TE-polarized structure. Also, the spontaneous emission rate is found to be 6.57 × 1027 s - 1 cm - 3 eV - 1 at 1288.21 nm with the carrier density of 5 × 1019 cm - 3. Furthermore, the radiative current density and the radiative recombination rate are found to be 121.92 A cm - 2 and 6.35 × 1027 s - 1 cm - 3, respectively, while the TE-polarized optical gain of the structure is 3872.1 cm - 1 at 1301.7 nm.

    The small intestinal (SI) microbiota has an essential role in the maintenance of human health. However, data about the indigenous bacteria in SI as affected by probiotics are limited. In our study, the short-term and long-term effects of a probiotic candidate, Lactobacillus plantarum ZDY2013, on the SI microbiota of C57BL/6J mice were investigated by the Illumina HiSeq (Novogene Bioinformatics Technology Co., Ltd., Tianjin, China) platform targeting the V4 region of the 16S rDNA. A total of 858,011 sequences in 15 samples were read. The α diversity analysis revealed that oral administration with L. plantarum ZDY2013 for 3 wk led to a significant increase in the richness and diversity of the SI bacterial community. Principal coordinate analysis and unweighted pair-group method with arithmetic means analysis showed a clear alteration in the SI microbiota composition after 3 wk of L. plantarum ZDY2013 treatment, although these changes were not found 6 wk after ceasing L. plantarum ZDY2013 administration. Species annotation showed that the dominant phyla in SI microbiota were Firmicutes, Bacteroidetes, Proteobacteria, and Verrucomicrobia. Interestingly, operational taxonomic unit cluster analysis showed that administration with L. plantarum ZDY2013 for 3 wk significantly increased the abundance of Proteobacteria, but decreased that of Bacteroidetes. Linear discriminant analysis coupled with effect size identified 18 bacterial taxa (e.g., Ruminococcus spp. and Clostridium spp.) that overgrew in the SI microbiota of the mice administered with L. plantarum ZDY2013 for 3 wk, and most of them belonged to the phyla Bacteroidetes and Proteobacteria. However, only one bacterial taxon (e.g., Nocardioides spp.) was over-represented in the SI microbiota of mice 6 wk after L. plantarum ZDY2013 administration. Overall, this study shows that oral administration with probiotic results in an important but transient alteration in the microbiota of SI. Copyright © 2016 American Dairy

    Full Text Available An argument that many foreign language students encounter oral communication problems while they try to express their meaning to their partners has encouraged a number of eminent scholars to analyze the use of communication strategies based on the type of the task activity and the level of proficiency. In this paper, the task type effect and the students’ proficiency levels on the communication strategies employed by Kosovan and Bosnian speakers of English were investigated. The purpose of the study was to determine if the students’ proficiency levels and the task type influenced the choice and the number of communication strategies at lexical degree in verbal communication. The study numbered 20 participants in total; Kosovan and Bosnian languages that use English as a foreign language. The subjects were selected upon their degree of proficiency (i.e. Elementary and Intermediate levels and were asked to carry out three different types of the tasks: ten minutes of oral communication, picture story narration and photographic description. The data of the assigned tasks came from audio and video-recording. Thus, the current study used the taxonomy of communication strategies employed by Tarone (1977. Likewise, the communication strategies used by both levels of the students were observed and compared in special instances. It was summarized that the task type and the level of proficiency influenced the number and the choice of different communication strategies in verbal performances. To indicate the present observable facts, two main aspects of the nature of the given tasks were pointed out: context in the task and task demands, respectively.

    The aim of the study was to determine the effects of a simulated communication training course on nurses' communication competence, self-efficacy, communication performance, myocardial infarction knowledge, and general satisfaction with their learning experience. A randomized controlled trial was conducted with a pre-test and two post-tests. The experimental group underwent simulated communication training course and the control group received a case-based communication training course. The experimental group made more significant improvement in competence and self-efficacy in communication from pre-test to the second post-test than the control group. Although both groups' satisfaction with their learning experience significantly increased from the first post-test to the second post-test, the experimental group was found to be more satisfied with their learning experience than the control group. No significant differences in communication performance and myocardial infarction knowledge between the two groups were identified. Scenario-based communication training can be more fully incorporated into in-service education for nurses to boost their competence and self-efficacy in communication and enhance their communication performance in myocardial infarction patient care. Introduction of real-life communication scenarios through multimedia in communication education could make learners more motivated to practice communication, hence leading to improved communication capacity.

  6. Short-term effect of antibiotics on human gut microbiota.

    Directory of Open Access Journals (Sweden)

    Suchita Panda

    Full Text Available From birth onwards, the human gut microbiota rapidly increases in diversity and reaches an adult-like stage at three years of age. After this age, the composition may fluctuate in response to external factors such as antibiotics. Previous studies have shown that resilience is not complete months after cessation of the antibiotic intake. However, little is known about the short-term effects of antibiotic intake on the gut microbial community. Here we examined the load and composition of the fecal microbiota immediately after treatment in 21 patients, who received broad-spectrum antibiotics such as fluoroquinolones and β-lactams. A fecal sample was collected from all participants before treatment and one week after for microbial load and community composition analyses by quantitative PCR and pyrosequencing of the 16S rRNA gene, respectively. Fluoroquinolones and β-lactams significantly decreased microbial diversity by 25% and reduced the core phylogenetic microbiota from 29 to 12 taxa. However, at the phylum level, these antibiotics increased the Bacteroidetes/Firmicutes ratio (p = 0.0007, FDR = 0.002. At the species level, our findings unexpectedly revealed that both antibiotic types increased the proportion of several unknown taxa belonging to the Bacteroides genus, a Gram-negative group of bacteria (p = 0.0003, FDR<0.016. Furthermore, the average microbial load was affected by the treatment. Indeed, the β-lactams increased it significantly by two-fold (p = 0.04. The maintenance of or possible increase detected in microbial load and the selection of Gram-negative over Gram-positive bacteria breaks the idea generally held about the effect of broad-spectrum antibiotics on gut microbiota.

  7. Environmental effects of energy forest (short rotation willow)

    Frank, K.

    1994-01-01

    This paper deals with environmental effects of producing and combusting energy forest fuel. Energy forest means short rotation willow (Salix). Supposed effects of sewage sludge application are discussed as well. Energy forestry on agricultural land implies both advantages and disadvantages for the environment. Leaf litter (humified leaves) increases the humus content in the top soil. The soil fauna is also positively affected. Until now performed studies about nitrogen leakage from fields cultivated with energy forest (Salix), have not given any distinct results. A retarded drainage within energy forest fields is on the other hand noticed. While the root system of Salix is active during a long period of the year, the nitrogen leakage become less compared to traditional cultivation. The content of plant nutrients and organic matter in sewage sludge make a resource that can be useful for agricultural purposes, especially for energy forest cultivation. The content of heavy metals and organic emissions contradicts sludge application to agricultural land. Sewage sludge with todays quality increases somewhat the content of heavy metals in the soil. This condition can be counteracted to a certain extent by growing energy forest. It has been established that Salix has high ability to heavy metal uptake, especially cadmium. Growing energy forest on drained farm land is connected with a risk for root penetration into the drainage system. With enough water and plant nutrients in the top soil the risk is reduced. Shallow depth of the pipes increases the risk. Combustion of wood chip from energy forests (and other types of biomass) gives especially two advantages. It does not give any net contribution of carbon dioxide to the atmosphere. The sulphur discharge will be minimal since the sulphur content in wood fuels is low. Discharge of nitrogen oxide and hydrocarbons may give some problems. These can be reduced by technological measures when combusting. 27 refs, 4 tabs

    Full Text Available The effect of communicating social psychology research findings on ingroup bias in a classroom setting has been investigated. Two hundred and twenty one high school students either read or did not read a brief report about three classical social psychological studies, then completed evaluation scales for the ingroup and the outgroup. Participants’ motivation was manipulated, and the messages were different as regards the congruency between the content and participants’ actual intergroup experience. Results showed that communication exerted a significant effect in reducing ingroup bias for participants in the high motivation/high congruency condition, that is, the communication effect was moderated by the individual’s level of motivation and the content of the arguments proposed in the report. Practical implications of results for education work and stereotype change, limitations of the study, as well as possible directions for future research are discussed.

    The Idaho National Engineering and Environmental Laboratory (INEEL) received ISO 14001/EMS certification in June 2002. Communication played an effective role in implementing ISO 14001/EMS at the INEEL. This paper describes communication strategies used during the implementation and certification processes. The INEEL achieved Integrated Safety Management System (ISMS) and Voluntary Protection Program (VPP) Star status in 2001. ISMS implemented a formal process to plan and execute work. VPP facilitated worker involvement by establishing geographic units at various facilities with employee points of contact and management champions. The INEEL Environmental Management System (EMS) was developed to integrate the environmental functional area into its ISMS and VPP. Since the core functions of ISMS, VPP, and EMS are interchangeable, they were easy to integrate. Communication is essential to successfully implement an EMS. (According to ISO 14001 requirements, communication interacts with 12 other elements of the requirements.) We developed communication strategies that integrated ISMS, VPP, and EMS. For example, the ISMS, VPP, and EMS Web sites communicated messages to the work force, such as “VPP emphasizes the people side of doing business, ISMS emphasizes the system side of doing business, and EMS emphasizes the systems to protect the environment; but they all define work, identify and analyze hazards, and mitigate the hazards.” As a result of this integration, the work force supported and implemented the EMS. In addition, the INEEL established a cross-functional communication team to assist with implementing the EMS. The team included members from the Training and Communication organizations, VPP office, Pollution Prevention, Employee and Media Relations, a union representative, facility environmental support, and EMS staff. This crossfunctional team used various communication strategies to promote our EMS to all organization levels and successfully implemented EMS

  10. Teamwork and communication: an effective approach to patient safety.

    2014-01-01

    Teamwork and communication failures are leading causes of patient safety incidents in health care. Though health care providers must work in teams, they are not well-trained in teamwork and communication skills. Health care faces the problems of differences in communication styles, communication failures and poor teamwork. There is enough evidence in the literature to show that communication failure is detrimental to patient safety. It is estimated that 80% of serious medical errors worldwide take place because of miscommunication between medical providers. NUH recognizes that effective communication and teamwork are essential in the delivery of high quality safe patient care, especially in a complex organization. NUH is a good example, where there is a rich mix of nationalities and races, in staff and in patients, and there is a rapidly expanding care environment. NUH had to overcome these challenges by adopting a multi-pronged approach. The trials and tribulations of NUH in this journey were worthwhile as the patient safety climate survey scores improved over the years.

    Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

    Combat resiliency is the ability of a commander to prosecute, control, and consolidate his/her's sphere of influence in adverse and changing conditions. To support this, an infrastructure must exist that allows the commander to view the world in varying degrees of granularity with sufficient levels of detail to permit confidence estimates to be levied against decisions and course of actions. An infrastructure such as this will include the ability to effectively communicate context and relevance within and across the battle space. To achieve this will require careful thought, planning, and understanding of a network and its capacity limitations in post-event command and control. Relevance and impact on any existing infrastructure must be fully understood prior to deployment to exploit the system's full capacity and capabilities. In this view, the combat communication network is considered an integral part of or National communication network and infrastructure. This paper will describe an analytical tool set developed at ORNL and RNI incorporating complexity theory, advanced communications modeling, simulation, and visualization technologies that could be used as a pre-planning tool or post event reasoning application to support response and containment.

  13. Dember effect photodetectors and the effects of turbulence on free-space optical communication systems

    Science.gov (United States)

    Dikmelik, Yamac

    High-speed free-space optical communication systems have recently utilized components that have been developed for fiber-optic communication systems. The received laser beam in such a system must be coupled into a single-mode fiber at the input of a commercially available receiver module or a wavelength division demultiplexer. However, one effect of propagation through atmospheric turbulence is that the spatial coherence of a laser beam is degraded and the percentage of the available power that can be coupled into the single-mode fiber is limited. This dissertation presents a numerical evaluation of fiber coupling efficiency for laser light distorted by atmospheric turbulence. The results for weak fluctuation conditions provide the level of coupling efficiency that can be expected for a given turbulence strength. In addition, the results show that the link distance must be limited to 400 m under moderate turbulence conditions if the link budget requires a coupling efficiency of 0.1. We also investigate the use of a coherent fiber array as a receiver structure to improve the fiber coupling efficiency of a free-space optical communication system. Our numerical results show that a coherent fiber array that consists of seven subapertures would increase fiber coupling efficiency by a significant amount for representative turbulence conditions and link distances. The use of photo-emf detectors as elements of a wavefront sensor for an adaptive optics system is also considered as an alternative method of reducing the effects of turbulence on a free-space optical communication system. Dember and photo-emf currents are investigated in silicon photoconductive detectors both theoretically and experimentally. Our results show that Dember photocurrents dominate the response of high-purity silicon samples with top surface electrodes to a moving interference pattern. The use of surface electrodes leads to shadowed regions beneath the electrodes and Dember photocurrents appear

    A self-propelled artificial microswimmer is often modeled as a ballistic Brownian particle moving with constant speed aligned along one of its axis, but changing direction due to random collisions with the environment. Similarly to thermal noise, its angular randomization is described as a memoryless stochastic process. Here, we speculate that finite-time correlations in the orientational dynamics can affect the swimmer’s diffusivity. To this purpose, we propose and solve two alternative models. In the first one, we simply assume that the environmental fluctuations governing the swimmer’s propulsion are exponentially correlated in time, whereas in the second one, we account for possible damped fluctuations of the propulsion velocity around the swimmer’s axis. The corresponding swimmer’s diffusion constants are predicted to get, respectively, enhanced or suppressed upon increasing the model memory time. Possible consequences of this effect on the interpretation of the experimental data are discussed.

  15. Short communication: Influence of labeling on Australian and Chinese consumers' liking of milk with short (pasteurized) and long (UHT) shelf life.

    Sixty percent of milk consumed in China has a long shelf life (UHT), presumably because milk with a short shelf life (pasteurized) is comparatively expensive. This in contrast to Australia, where 10% of consumed milk is UHT and the price between UHT and pasteurized milk is equivalent. Whether UHT is actually more liked than pasteurized milk by Chinese consumers is unknown. However, the potential positive halo around the expensive pasteurized milk might result in Chinese consumers liking milk more when it is labeled as "short shelf-life milk." To test these hypotheses, Chinese (n=48, 20 males, 28 females, 23 ± 7.2 yr) and Australian (n=93, 11 males, 82 females, 24 ± 5.6 yr) consumers tasted and rated (9-point hedonic scale), in a randomized order, 3 × 30-mL samples of UHT milk (labeled as "long shelf-life milk," "short shelf-life milk," or "milk") and 3 × 30-mL samples of pasteurized milk (also labeled as "long shelf-life milk," "short shelf-life milk," or "milk"). Australian participants' liking of milk was not influenced by labeling. Regardless of what the label stated, they always preferred the taste of pasteurized milk over the taste of UHT milk. This was different for Chinese participants, who preferred the taste of UHT milk over the taste of pasteurized milk, but in general had a higher liking for any milk that was labeled "short shelf-life milk." Both Australian and Chinese were more positive about pasteurized than UHT milk. In conclusion, Chinese, but not Australian, consumers' liking of milk was guided by the positive expectations of pasteurized milk and the negative expectations of UHT milk. Further research is needed to investigate if the present findings can be extrapolated to a larger and more varied group of Chinese and Australian consumers.

    Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

    Intra-team communication plays an important role in team effectiveness in various domains including sport. As such, it is a key consideration when introducing new tools within systems that utilise teams. The difference in intra-team communication of Australian Rules Football (AFL) umpiring teams was studied when umpiring with or without radio communications technology. A cross-sectional observational study was conducted to analyse the verbal communication of seven umpiring teams (20 participants) grouped according to their experience with radio communication. The results identified that radio communication technology increased the frequency and altered the structure of intra-team communication. Examination of the content of the intra-team communication identified impacts on the 'Big Five' teamwork behaviours and associated coordinating mechanisms. Analysis revealed that the communications utilised did not align with the closed-loop form of communication described in the Big Five model. Implications for teamwork models, coaching and training of AFL umpires are discussed. Practitioner Summary: Assessing the impact of technology on performance is of interest to ergonomics practitioners. The impact of radio communications on teamwork is explored in the highly dynamic domain of AFL umpiring. When given radio technology, intra-team communication increased which supported teamwork behaviours, such as backup behaviour and mutual performance monitoring.

    Limited disease knowledge is frequently the cause of disease-related anxiety in myocardial infarction patients. The ability to communicate effectively serves multiple purposes in the professional nursing practice. By communicating effectively with myocardial infarction patients, nurses may help reduce their anxiety by keeping them well informed about their disease and teaching them self-care strategies. This research evaluates the communication skills of nurses following scenario-based simulation education in the context of communication with myocardial infarction patients. This study used an experimental design and an educational intervention. The target population comprised nurses of medicine (clinical qualified level N to N2 for nursing) working at a municipal hospital in Taipei City, Taiwan. A total 122 participants were enrolled. Stratified block randomization divided participants into an experimental group and a control group. The experimental group received clinical scenario-based simulation education for communication. The control group received traditional class-based education for communication. Both groups received a pre-test and a Communication Skills Checklist post-test assessment. Results were analyzed using SPSS 17.0 for Windows software. A t-test showed significant increases in communication skills (p skills following the education intervention. The results indicate that clinical scenario-based simulation education for communication is significantly more effective than traditional class-based education in enhancing the ability of nurses to communicate effectively with myocardial infarction patients.

  1. Chaos-based wireless communication resisting multipath effects

    In additive white Gaussian noise channel, chaos has been shown to be the optimal coherent communication waveform in the sense of using a very simple matched filter to maximize the signal-to-noise ratio. Recently, Lyapunov exponent spectrum of the chaotic signals after being transmitted through a wireless channel has been shown to be unaltered, paving the way for wireless communication using chaos. In wireless communication systems, inter-symbol interference caused by multipath propagation is one of the main obstacles to achieve high bit transmission rate and low bit-error rate (BER). How to resist the multipath effect is a fundamental problem in a chaos-based wireless communication system (CWCS). In this paper, a CWCS is built to transmit chaotic signals generated by a hybrid dynamical system and then to filter the received signals by using the corresponding matched filter to decrease the noise effect and to detect the binary information. We find that the multipath effect can be effectively resisted by regrouping the return map of the received signal and by setting the corresponding threshold based on the available information. We show that the optimal threshold is a function of the channel parameters and of the information symbols. Practically, the channel parameters are time-variant, and the future information symbols are unavailable. In this case, a suboptimal threshold is proposed, and the BER using the suboptimal threshold is derived analytically. Simulation results show that the CWCS achieves a remarkable competitive performance even under inaccurate channel parameters.

    In this study, the impact of including a bone conduction transducer in a three-channel spatialized communication system was investigated. Several military and security forces situations require concurrent listening to three or more radio channels. In such radio systems, spatial separation between three concurrent radio channels can be achieved by delivering separate signals to the left and right earphone independently and both earphones simultaneously. This method appears to be effective; however, the use of bone conduction as one channel may provide both operational and performance benefits. Three three-channel communication systems were used to collect speech intelligibility data from 18 listeners (System I, three loudspeakers; System 2, stereo headphones; System 3, stereo headphones and a bone conduction vibrator). Each channel presented signals perceived to originate from separate locations. Volunteers listened to three sets of competing sentences and identified a number, color, and object spoken in the target sentence. Each listener participated in three trials (one per system). Each trial consisted of 48 competing sentence sets. Systems 2 and 3 were more intelligible than System I. Systems 2 and 3 were overall equally intelligible; however, the intelligibility of all three channels was significantly more balanced in System 3. Replacing an air conduction transducer with a bone conduction transducer in a multichannel audio device can provide a more effective and balanced simultaneous monitoring auditory environment. These results have important design and implementation implications for spatial auditory communication equipment.

JNES has developed the information system specified as Protection of Nuclear Power Plants against Tsunamis and Post Earthquake considerations in the External Zone (TiPEEZ) as part of IAEA International Seismic Safety Centre (ISSC) Extra Budgetary Programme (EBP). The EBP is currently preparing technical documents (TECDOC) regarding the implementation of the TiPEEZ. After the Fukushima accident, there has been increasing demand for disaster mitigation systems to share risk information between nuclear organizations and local municipalities. JNES and Niigata Institute of Technology conduct implementation of TiPEEZ for the practical use based on the corroborative works with Kashiwazaki city and citizens. (author)

    Patients are increasingly attracted to homeopathy despite the unproven effectiveness of homeopathic remedies. Clinical benefit of homeopathy may be due to communication. This review aims to identify and assess effective communication patterns in homeopathy. Narrative review and synthesis of published communication patterns, patient narratives and the author's professional experience as a homeopathic practitioner. In the biomedical model, where the focus is on disease, communication is physician-centered with early redirection of patients' concerns, and associated with reduced compliance, increasing risk of malpractice claims and low professional fulfillment. The biopsychosocial and the developing integrative medicine models are based on biomedicine but aim to include the whole person. Patient-centeredness is a behavior that elicits, respects and incorporates patients' wishes, allows active patient participation and is related to improved outcomes. The homeopathic model is based on holism and comprehension of the totality of the patient and uses patient-centered communication with a high degree of physician co-operation, empathy, hopefulness, enablement and narrative competence, all of which can improve outcomes. Both biopsychosocial and homeopathic models rely on patient-centered communication. Regardless of conceptual differences, they overlap in their common respect for the totality and individuality of the patient. The study of the homeopathic model shows that respect for the whole person is a basic requirement to entrench patient-centeredness more firmly in medicine. Medical education should include values such as individual coping strategies, the benefits of a sound and healthy life-style and the necessity of hope and enablement. Health care should be redesigned to honor physicians who practice these values.

    Many children with autism require intensive instruction in the use of augmentative or alternative communication systems, such as the Picture Exchange Communication System (PECS). This study investigated the use of PECS with three young boys with autism to determine the impact of PECS training on use of pictures for requesting, use of intelligible words, and maladaptive behaviors. A multiple baseline-probe design with a staggered start was implemented. Results indicated that all of the participants quickly learned to make requests using pictures and that two used intelligible speech following PECS instruction; maladaptive behaviors were variable throughout baseline and intervention phases. Although all of the participants improved in at least one dependent variable, there remain questions regarding who is best suited for PECS and similar interventions.

    Communication is essential to safe flight, as evidenced by several accidents in which crew communicates was found to have contributed to the accidents. This chapter documents the essential role of explicit efficient communication to flight safety with a global context. It addresses communication between flight crews and air traffic controllers in regions a the world where pilots and controllers speak different native languages, as well as cases in which crew members within the flight deck represent different native languages and cultures. It also addresses problems associated with "exporting" crew resource management training programs to parts of the world which values and norms differ from those of the United States, where these programs were initially developed. This chapter is organized around several central questions: (1) What are various kinds of communication failures and what are their consequences; (2) What are the causes of communication failure; (3) What are features of effective crew communication; (4) What can be done to enhance communication success? To explore a wider range of communication failures than available from accident reports, we examined a set of incident reports from the Aviation Safety Reporting System. These could be classified into three major categories: those in which language actually interfered with transmission of a message; those in which transmission was adequate but the context was not expressed unambiguously and thus the message received was not the same as the message intended; and those in which the message was received as intended, but was not adequately understood or acted upon, mainly because of cultural factors. The consequences of failed communication can be flight errors (such as when a clearance is not received correctly), loss of situation awareness, or failure of crew members (or ATC and pilots) to build a shared understanding of a situation. Causes of misunderstanding can be traced to a number of sources, often

    Full Text Available Artists in Nigeria perceived effective communication differently irrespective of the socio-economic status.Communication effectiveness depends largely on the understanding of the message being passed between a sender and a receiver. Painting has been used over time to express emotion and feeling to the perceiving audience. The study is audience’s perception of communication in Nigeria painting and how it varies with the socio-economic characteristics such as age, education, gender, and being professional artist or art lovers. Questionnaires were distributed and administered to examine how the status of the art audience makes or mars effective communication in painting. The inferential statistics that were employed include “chi-square test” to test the relationship between different variables. The data were taken in ordinal form using Likert’s scale, and transformed into interval data. This was done by attaching statistical weights to the responses in the order of importance which were summed up for the parametric testing. Findings show that gender factor has nothing to do with the understanding of paintings. Also, the level of education obtained by the audience does not have much to do with understanding of contemporary Nigerian painting but a better exposure to the issue concerning the stylistic development of Nigerian painting. Art practitioners must adequately be guided on stylistic trend in painting, art education should be more intensified in educational curriculum in Nigeria. The paper concludes that audience requires a better exposure to the issues concerning the stylistic development of Nigerian painting for effective communication to take place.

    Effective communication between nurses and patients with dementia promotes the quality of patient care by improving the identification of patient needs and by reducing the miscommunication-related frustration of patients and nurses. This study evaluates the effects of an advanced innovative Internet-based communication education (AIICE) program on nurses' communication knowledge, attitudes, frequency of assessing patient communication capacity, and communication performance in the context of care for patients with dementia. In addition, this study attempts to evaluate the indirect effects of this program on outcomes for patients with dementia, including memory and behavior-related problems and depressive symptoms. A quasi-experimental research design with a one-group repeated measure was conducted. Convenience sampling was used to recruit nurses from long-term care facilities in southern Taiwan. Data were analyzed using general estimating equations to compare changes over time across three points: baseline, fourth-week posttest, and 16th-week posttest. One hundred five nurses completed the AIICE program and the posttest surveys. The findings indicate that nurses' communication knowledge, frequency in assessing patients' communication capacity, and communication performance had improved significantly over the baseline by either the 4th- or 16th-week posttest (p < .01). However, communication attitude showed no significant improvement in the posttest survey (p = .40). Furthermore, the findings indicate that the memory and behavior-related problems and the depressive symptoms of patients had decreased significantly by the 16th-week posttest (p = .05). This study showed that the AIICE program improves nurses' communication knowledge, frequency to assess patients' communication capacity, and communication performance and alleviates the memory and behavior-related problems and depressive symptoms of patients. The continuous communication training of nurses using the

    This study evaluated a pilot workshop for teaching communication skills to dental students. The methodology is based on an experiential learning approach, the use of realistic clinical scenarios, simulated patients, and an integrated teaching team of both educational researchers and dentists. Furthermore, the methodology was adapted for short workshops, which is thought to offer better possibilities for frequent and effective training of communication skills throughout the curriculum. The work-shop was piloted with groups of six to ten students from the sixth and tenth semesters (n=94). Results show that the majority of students found the tasks meaningful and well aligned with how they perceived their future profession as dentists. Most students also thought that they learned from the task. An interesting finding is that students not only found it instructive to practice how to communicate in authentic situations, but that they generally found the workshop to be thought-provoking while at the same time providing structure and intellectual tools for the future. A possible explanation for this finding is the sharing of explicit criteria for high-quality communication.

    To characterize the effects of caregiver mental health and coping strategies on interactions with an injured adolescent acutely after traumatic brain injury (TBI). Multi-site, cross-sectional study. Outpatient setting of 3 tertiary pediatric hospitals and 2 tertiary general medical centers. Adolescents (N = 125) aged 12-17 years, 1-6 months after being hospitalized with complicated mild to severe TBI. Data were collected as part of a multi-site clinical trial of family problem-solving therapy after TBI. Multiple regression analyses were used to examine the relationship of caregiver and environmental characteristics to the dimensions of effective communication, warmth, and negativity during caregiver-adolescent problem-solving discussions. Adolescent and caregiver interactions, as measured by the Iowa Family Interaction Rating Scales. Caregivers who utilized problem-focused coping strategies were rated as having higher levels of effective communication (P teen interactions. Problem-focused coping strategies are associated with higher levels of effective communication and lower levels of caregiver negativity during the initial months after adolescent TBI, suggesting that effective caregiver coping may facilitate better caregiver-adolescent interactions after TBI.

    Bright lines in environmental risk communication refer to the specific levels at which an environmental risk becomes a serious health threat and action should be taken to mitigate its effects. This study examined the effect of ''bright lines'' in risk communication by emphasizing the radon exposure threshold level of 4 picocuries per liter. Specifically, the authors developed a computer-assisted interview containing bright-line versions of risk information. The bright-line version contained a range of possible radon levels, the corresponding number of estimated lung cancer cases, the relative health risk from radon compared to other health risks, and the EPA guidelines for mitigating levels above 4 picocuries in the home. The non-bright line version was identical to the bright-line version, except it did not include the EPA's mitigation recommendations. Effect measures included respondents' change in perceived risk after reading their materials, intended testing behavior, and advice to their neighbor for a specified radon level either above or below the 4 picocury threshold level. This paper discusses broader policy implications for designing effective risk communication programs

    Hugman, Bruce; Edwards, I Ralph

    2006-07-01

    Rational use of drugs and patient safety are seriously compromised by a lack of good information, education and effective communication at all stages of drug development and use. From animal trials through to dispensing, there are misconceptions and opportunities for error which current methods of drug information communication do not adequately address: they do not provide those responsible for prescribing and dispensing drugs with the data and information they need to pass on complex and often changing messages to patients and the public. The incidence of adverse reactions due to the way drugs are used; the variable impact of regulatory guidelines and warnings on prescribing behaviour; drug scares and crises suggest a great gap between the ideals of the safe use of medicines and the reality in homes, clinics and hospitals around the world. To address these challenges, the authors review the several levels at which safety information is generated and communicated, and examine how, at each stage, the content and its significance, and the method of communication can be improved.

    Many type 2 diabetes mellitus patients have difficulties reaching optimal blood glucose control. With patients treated in primary care by nurses, nurse communication plays a pivotal role in supporting patient health. The twofold aim of the present review is to categorize common barriers to nurse-patient communication and to review potentially effective communication methods. Important communication barriers are lack of skills and self-efficacy, possibly because nurses work in a context where they have to perform biomedical examinations and then perform patient-centered counseling from a biopsychosocial approach. Training in patient-centered counseling does not seem helpful in overcoming this paradox. Rather, patient-centeredness should be regarded as a basic condition for counseling, whereby nurses and patients seek to cooperate and share responsibility based on trust. Nurses may be more successful when incorporating behavior change counseling based on psychological principles of self-regulation, for example, goal setting, incremental performance accomplishments, and action planning. © The Author(s) 2014.

    Not only neurologists but also ENT-physicians and phoniatricians have to prescribe speech and language therapy for patients with communication disorders. Complementary and alternative medicine (CAM) has gained increasing popularity among patients. Many studies have investigated these procedures and positive effects on certain physical e. g., chronic pain and anxiety disorders could be validated. Unfortunately only few empirical investigations have targeted the use of CAM to treat neurogenic disorders of communication or cognition. In this review we provide an overview over general therapeutical principals of two widely used approaches, relaxation therapy and acupuncture. Then we survey the literature and summarize existent research literature regarding the effects of the treatment of neurogenic disorders including dementia.

    This paper connects the effects of social media on terror/anti-terror communication with dynamics and consequences of surveillance. Citizens become via social media more independent from mass media and more interconnected. This is also valid when citizens engage in terror/anti-terror communication...... that social media contribute to extending surveillance: by being a temptation for intelligence services, by not resisting state authorities and via constructing threat perceptions among populations which in effect deliver security politicians ‘windows of opportunity’ in order to implement ever more....... However, via social media citizens also become targets of the ‘collect-it-all’ surveillance, which was revealed to the global public in 2013. I argue that due to such surveillance some citizens might start to censor themselves and that surveillance inflicts with a number of human rights. I further argue...

    The purpose of this study was to examine the effects of short-term GSM (Global System for Mobile Communications) cellular phone base station RF-EMF (radiofrequency electromagnetic fields) exposure on psychological symptoms (good mood, alertness, calmness) as measured by a standardized well-being questionnaire. Fifty-seven participants were selected and randomly assigned to one of three different exposure scenarios. Each of those scenarios subjected participants to five 50-min exposure sessions, with only the first four relevant for the study of psychological symptoms. Three exposure levels were created by shielding devices in a field laboratory, which could be installed or removed during the breaks between sessions such that double-blinded conditions prevailed. The overall median power flux densities were 5.2 microW/m(2) during "low," 153.6 microW/m(2) during "medium," and 2126.8 microW/m(2) during "high" exposure sessions. For scenario HM and MH, the first and third sessions were "low" exposure. The second session was "high" and the fourth was "medium" in scenario HM; and vice versa for scenario MH. Scenario LL had four successive "low" exposure sessions constituting the reference condition. Participants in scenarios HM and MH (high and medium exposure) were significantly calmer during those sessions than participants in scenario LL (low exposure throughout) (P = 0.042). However, no significant differences between exposure scenarios in the "good mood" or "alertness" factors were obtained. We conclude that short-term exposure to GSM base station signals may have an impact on well-being by reducing psychological arousal. (c) 2008 Wiley-Liss, Inc.

    The degradation of the performance of digital communication systems because of ionospheric scintillation effects can be reduced either by diversity techniques or by coding. The effectiveness of traditional space-diversity, frequency-diversity and time-diversity techniques is reviewed and design considerations isolated. Time-diversity signaling is then treated as an extremely simple form of coding. More advanced coding methods, such as diffuse threshold decoding and burst-trapping decoding, which appear attractive in combatting scintillation effects are discussed and design considerations noted. Finally, adaptive coding techniques appropriate when the general state of the channel is known are discussed.

    Makely, S

    1990-07-01

    Teaching students to communicate effectively with patients has always been part of the radiography curriculum in the USA. However, developing these skills has become even more important in recent times due to several factors. Patients who have been well versed in what to expect from the examination being conducted are in a better position to co-operate with the radiographer. This increases the chances of producing optimal results from an examination at the first attempt, thus reducing radiation exposure, patient discomfort and the overall cost of conducting the procedure. Also, increased competition among health care providers has resulted in more emphasis being placed on patient, or customer, satisfaction. Radiographers are in the 'front line' of patient care. Patients often have more interaction with radiographers than with physicians or other medical specialists. Radiographers who practise effective communication techniques with their patients can alleviate anxiety and make an important contribution to the overall satisfaction of the patient with respect to the quality of service and care they receive. This article describes instructional methods being used in the USA to help develop effective patient communication techniques, and reports the findings of a study among radiography educators as to which of these methods are thought to be most successful.

    Full Text Available Aim of study: The main aim of this study was to analyse the post-fire recruitment and growth of Pinus pinaster seedlings during the first five years after wildfire and also to analyse the effects of climatic conditions on the survival of P. pinaster seedlingsArea of study: The study area was located in a P. pinaster stand in León province (NW Spain burned in 1998.Material and Methods: Three sites in the burned area were selected. In each site three permanent transects of 20m x 1m were placed. In each transect, twenty 1m2 sampling units were marked and the number and height of each pine seedlings was recorded at 7, 8, 9, 10, 11, 12 months and 2, 3, 4 and 5 years after the wildfire. The soil of study area is Cambisol.Mean results: Mean Pinus regeneration densities varied between 33.2 seedlings/m2 after 7 months and 6 seedlings/m2 five years after wildfire. In this P. pinaster stand, maximum mortality appeared during the summer months in the first year of regeneration. There was a significant increase in seedling height associated with a decrease in density.Research highlights: The post-fire recruitment is considered enough to ensure good natural Pinus pinaster forest regeneration. In the short term post-fire management strategy in this type of forest could be the remaining branches with cones of burned trees that allow the dissemination of the seeds during the first few years after fire and ensure natural regeneration.Keywords: Fire effects; natural regeneration; León province (NW Spain; seedlings density; growth and survival.

    Those responsible for state and local radon programs often express frustration about the small share of homes that have been tested for radon, and the small share of those with high readings that have been mitigated. Several recent studies have examined how well alternative ways of communicating about radon's risk have accomplished the goals of motivating appropriate testing and mitigation. Unfortunately, the results of these studies have not reached practitioners. This paper is for them. It summarizes the practical implications that are most crucial for planning and implementing an effective radon risk communication program--a program that will motivate people to test for radon and mitigate when radon levels are high, without unduly alarming those whose radon levels are low
