Abstract Wireworms (Coleoptera: Elateridae) are major economic pests of Florida sugarcane (Saccharum spp. hybrid). The corn wireworm, Melanotus communis (Gyllenhal), is the most important wireworm pest of Florida sugarcane occurring in both sandy and muck soils. The objective of this study was to determine survivability, preference, and dispersal of wireworms in sandy and muck soils. There was no significant difference in starved wireworm survival between the soils after 2 mo. However, the starved wireworms gained more weight in muck soil than in sand. Wireworms dispersed at similar rates toward oat baits in both soil types. Interestingly, in free choice tests wireworms showed a high preference to reside in muck versus sandy soil, which corresponds to the greater wireworm weight change found in muck versus sandy soil. The high preference for muck and greater weight gain in muck found in this study partially explains why M. communis is more abundant in muck soils than in sandy soils in Florida sugarcane.

AbstractThe efficacy of the salt flotation technique using saturated solutions of sodium nitrate (specific gravity 1.30) and zinc sulphate (specific gravity 1.16) for separating Ascaris lumbricoides eggs from clay, loamy and sandy soils has been investigated. Ten samples of each of the egg concentrations of 100, 500, 2500, 5000 and 10,000 eggs/25 g of soil were used for each soil type. Using T-test and ANOVA, the number of eggs recovered from sand was significantly higher than from loam and the number from loam significantly higher than from clay. With sodium nitrate, the maximum egg recovery rate was 25.04% from sandy soil at a concentration of 500 eggs/25 g soil while with zinc sulphate it was 13.88% also from sandy soil and concentration of 500 eggs/25 g soil. While the number of eggs recovered increased with soil egg concentration, the percentage of eggs recovered is inversely proportional to egg concentration. The number of eggs recovered with sodium nitrate was significantly higher than with zinc sulphate solution in the three soil types.

The aim of this study was to investigate the basketball players’, active in Turkey Women’s Basketball Super and 1st Leagues, empathy levels according to their marital status, educational status in addition to age and marital status of their coach; and to evaluate leadership characteristics and behavior of their coaches according to athlete’s perception. Another aim was to analyze the relation between empathy levels of the athletes and athletes’ perception of coaching behavior. 264 (age; 24.61±5.53 year) female athletes playing in Turkey Women’s Basketball Super and 1st Leagues participated in this study. Leadership Scale for Sports (LSS)-version of Athletes’ Perception of Coaching Behavior that developed by Chelladurai and Saleh, and adapted by Tiryaki and Toros in 2006 was used as data collection tool. Athletes’ perceptions of leadership style and behavior of their coach were evaluated in five different factors. A five-factor solution with 40 items describing the most salient dimensions of coaching behavior was selected as the most meaningful. Empathy levels of the athletes were determined by using Emphatic Tendency Scale which was developed by Dökmen (1988) and composed of 20 items. Empathy levels of the athletes showed no statistically significant difference in terms of any variable (p>0.05). There was no statistically significant difference in athletes’ perceptions of coaching behaviors in terms of marital status of the athlete and age of their coach (p>0.05). In terms of educational status of athletes and marital status of their coach, there were statistically significant differences in athletes’ perceptions of coaching behaviors (p<0.05 and p<0.01). Positive and meaningful correlation was found between empathy scores of the athletes and training and instruction behavior (r=.172**) and autocratic behavior (r=.154*) of the coach (p<0.05 and p<0.01). Educational status of the athletes and marital status of their coach are influental in athletes’ evaluation of their perceptions of coaching behavior. Empathy levels of the athletes are related to their perceptions of coaching behavior.

BACKGROUND Gingivitis is a non-painful, inflammatory condition that can be treated with home remedies. Left untreated gingivitis can lead to tooth loss. Periodic dental examinations are important for early diagnosis and treatment of gum diseases. In order to contain the spread of the corona virus, governments, including in Israel, have restricted movements of their citizens which has caused routine dental checkups to be postponed. OBJECTIVE This study aimed to examine the ability of an mHealth app- iGAM to reduce gingivitis. METHODS A prospective observational cohort study was performed, 160 unpaid participants were divided into 2 equal groups and downloaded the iGAM app. Group 1 photographed their gums weekly for eight weeks. Group 2 photographed their gums at the time of recruitment and 8 weeks later. After photo submission, the participants received the message "It is recommended to read the information contained within the app regarding maintaining oral hygiene habits". A single blinded researcher examined the images and scored them according to the Modified Gingival Index (MGI). RESULTS The average age of group 1 was 26.77 (S.D. ± 7.43), and 28.53 (S.D. ± 10.44) for group 2. The majority were male (74.7% in group 1 vs. 66.7% in group 2), most participants described themselves as "secular", most were "single", non-smokers (74.7% vs. 78.4%) and did not take medications (85.3% vs. 78.4%). 126 subjects completed the study. A statistically significant difference (P <.001) was found in the dependent variable (MGI) in a linearly negative manner. As time passed, the gum condition improved, there were significantly lower gingivitis scores in group 1 (M = 1.16, S.D. ± 1.18) compared to group 2 (M = 2.16, S.D. ± 1.49), after eight weeks. Those with more recent dental visits had a lower MGI (p = .037). No association was found between knowledge and behavior, most participants were familiar with the recommendations for maintaining oral health, yet they only performed some. CONCLUSIONS A dental selfie taken once a week using an mHealth app (iGAM) reduced the signs of gingivitis and promoted oral health. During the current pandemic where social distancing recommendations may be causing people to avoid dental clinics, this app can remotely promote gum health. CLINICALTRIAL The protocol was approved by Hadassah research ethics committee (IRB, 0212-18-HMO)

Water Holding

In recent years, plants in sandy soils have been impacted by increased climate variability due to weak water holding and temperature buffering capacities of the parent material. The projected impact spreads all over the world, including New England, USA. Many regions of the world may experience an increase in frequency and severity of drought, which can be attributed to an increased variability in precipitation and enhanced water loss due to warming. The overall benefits of biochar in environmental management have been extensively investigated. This review aims to discuss the water holding capacity of biochar from the points of view of fluid mechanics and propose several prioritized future research topics. To understand the impacts of biochar on sandy soils in-depth, sandy soil properties (surface area, pore size, water properties, and characteristics) and how biochar could improve the soil quality as well as plant growth, development, and yield are reviewed. Incorporating biochar into sandy soils could result in a net increase in the surface area, a stronger hydrophobicity at a lower temperature, and an increase in the micropores to maximize gap spaces. The capability of biochar in reducing fertilizer drainage through increasing water retention can improve crop productivity and reduce the nutrient leaching rate in agricultural practices. To advance research in biochar products and address the impacts of increasing climate variability, future research may focus on the role of biochar in enhancing soil water retention, plant water use efficiency, crop resistance to drought, and crop productivity.

Pragmatic Presupposition

Pragmatic presupposition focuses on the study of the relationship between the speaker and the hearer at the time of communication and the language they used. It can effectively serve advertising language from the linguistic field. In other words, pragmatic presupposition can meet some of the requirements of the advertisements. Nowadays people confront a variety of commercial advertisements, such as food advertisements, drink advertisements, digital product and cosmetic advertisements, etc. In fact, advertising language is the core factor which determines the success or failure of one commercial advertisement. Most domestic and overseas scholars have studied advertising language through cooperative principles，rhetoric and systemic-functional grammar, etc. However, they do not pay enough attention to the pragmatic presupposition manifested in both Chinese and English cosmetic advertisements. Therefore, this paper conducts a comparative study based on previous studies of pragmatic presupposition with new data. The data analyzed in this study are taken from some major fashion magazines in America, United Kingdom and China, such as VOGUE, Cosmopolitan，Trends health，etc. These cosmetic advertisements were advertised in the recent 20 years. Through the analysis, it is found that there is no significant difference between Chinese and English cosmetic advertisements in terms of types of pragmatic presupposition manifested. Both Chinese and English advertisers mainly adopt four types of pragmatic presupposition: existential presupposition, factive presupposition, state presupposition and behavior presupposition, and state presupposition takes up the largest proportion. The present study provides a more comprehensive analysis of pragmatic presupposition and classification of it. In addition, the results of this study also could help advertisers and consumers increase their mutual understanding.

The task of this study was to investigate the level of satisfaction of various categories of crime victims with various aspects of police work and behavior. The aim of this research was to examine whether the police treat all victims of crime equally responsibly, or whether there is a significant difference in the satisfaction of various categories of crime victims with various aspects of police work and behavior. On an occasional sample of 150 examinees, we analyzed the level of satisfaction of crime victims in relation to the expectations of the police regarding the reported criminal offenses and then the level of satisfaction towards different aspects of work and conduct of the police, such as reporting crime to the police, environmental conditions of interview and human compassion/empathy of police officers. The results indicate a significant difference in the satisfaction of specified aspects of police work among different categories of victims. Most dissatisfaction was expressed by members of the LGBT community and convicted persons when they appear in the role of victims. The research makes recommendations for improving the quality of the work and behavior of the police towards victims of crime.

Today the issue of energy saving is acute. The main sources of energy are radiant energy of the Sun, wind energy, energy of moving water. Therefore, the issue of solving alternative energy sources is relevant. The article aims to solve the problem by using low-potential heat of the soil mass by means of energy-efficient building constructions - foundations. It is necessary to know the thermal characteristics of soils for this. At the moment, methods for determining the thermophysical properties of inert materials with subsequent practical application in the field of construction have been widely studied, but no one of these methods takes into account the grain-size composition. Thus, the study of the connection between the thermal conductivity and the grain-size composition of the soil is important. The aim of the work is to Estimation of thermal conductivity of sandy soils based on grain-size composition. This article presents an analysis of the dependence of the thermal conductivity of the sandy soil of its grain-size composition. The matrix of experiment planning is made; the methodology and technological sequence of the experiment were tested. Statistical processing of the obtained experimental data was carried out. Based on a series of test experiments, it was concluded that there are two factors competing in its thermal conductivity: an increase in λ due to an increase in the degree of pore filling and a decrease in total heat conductivity due to a decrease in the degree of pore filling. These results suggest that grain-size composition has an impact on the thermal conductivity of the sandy soil. During the experiment, the dependence of the thermal conductivity of sandy soils on their grain-size composition was experimentally established.

The coconut rhinoceros beetle (CRB), Oryctes rhinoceros (L.) (Coleoptera: Scarabaeidae), has become one of the most important coconut and oil palm pests. This species was detected attacking coconut palms on Oʻahu, Hawaiʻi in December 2013, and an eradication program was initiated. One of the major challenges for eradication has been the identification of new breeding sites. Information on the factors influencing oviposition is needed to aid in finding sites likely to host the immature stages of this insect. In this study, a series of choice tests were conducted to assess the oviposition preferences of both laboratory-reared and wild-caught CRB. Mated females, of both lab-reared and wild-caught beetles, were offered for oviposition a choice between sand and two mulch substrates, one with small and one with large particle sizes. Both types of CRB laid eggs preferentially in substrate of small particle size rather than large and none laid eggs in sand. Lab-reared and wild-caught CRB differed in their oviposition behavior and size. These results can be used to aid in the identification of breeding sites for management programs and eradication efforts.
