Bullying Victimization, Negative Emotions, and Digital Self-Harm: Testing a Theoretical Model of Indirect Effects

ABSTRACT Research on digital self-harm – the anonymous or pseudonymous posting of hurtful or negative information about oneself on the internet and social media platforms – is in the early stages of development. While scholars have started to focus on the correlates of this behavior, there remains a need to anchor the study of digital self-harm within established theoretical frameworks. Herein, we draw on Agnew’s general strain theory to examine whether negative emotions mediate the association between bullying victimization and digital self-harm. Using data collected from adolescents participating in the 2019 Florida Youth Substance Abuse Survey (N = 9,469; M grade level = 8.78; 47% Male; 32% White, non-Hispanic), a strong, positive association between bullying victimization and digital self-harm is observed, as well as an indirect association operating through negative emotions. Discussion centers on the implications of the findings for theory and policy, as well as future directions for research on digital self-harm.
Key Factors Affecting the Deformation and Failure of Surrounding Rock Masses in Large-Scale Underground Powerhouses

The stability of the surrounding rock masses of underground powerhouses is always emphasized during the construction period. With the general trends toward large-scale, complex geological conditions and the rapid construction progress of underground powerhouses, deformation and failure issues of the surrounding rock mass can emerge, putting the safety of construction and operation in jeopardy and causing enormous economic loss. To solve these problems, an understanding of the origins and key affecting factors is required. Based on domestic large-scale underground powerhouse cases in the past two decades, key factors affecting the deformation and failure of the surrounding rock mass are summarized in this paper. Among these factors, the two most fundamental factors are the rock mass properties and in situ stress, which impart tremendous impacts on surrounding rock mass stability in a number of cases. Excavation is a prerequisite of surrounding rock mass failure and support that is classified as part of the construction process and plays a pivotal role in preventing and arresting deformation and failure. Additionally, the layout and structure of the powerhouse are consequential. The interrelation and interaction of these factors are discussed at the end of this paper. The results can hopefully advance the understanding of the deformation and failure of surrounding rock masses and provide a reference for design and construction with respect to hydroelectric underground powerhouses.

Synthesis of novel photoinitiators, spectroscopic (UV vis, fluorescence, steady state and time resolved), electrochemical and EPR studies of their photoinduced radical generation mechanisms, Z-scan measurements of their two-photon absorption cross section, two-photon polymerization at 532 nm, with a pulsed ns laser, material evaluation by scanning electron microscopy
Aegilops tauschii Introgressions Improve Physio-Biochemical Traits and Metabolite Plasticity in Bread Wheat under Drought Stress

With the aim of providing genetic materials for breeding drought-resistant wheat varieties, the physiological and metabolic plasticity of three drought-resistant wheat multiple synthetic derivative lines (MSDLs) and their backcross parent “Norin 61” (N61) were evaluated in response to drought stress. The results indicated that the D-genome introgressions from Aegilops tauschii into the MDSLs improved their drought-adaptive traits. Specifically, MNH5 and MSD345 showed higher photosynthesis rates and triose phosphate utilization than N61 under control conditions, resulting in greater accumulation of glucose and sucrose in the shoots. However, under drought stress, MNH5 and MSD345 had higher intrinsic water use efficiency than MSD53 and N61. The total antioxidant capacity and superoxide dismutase activity increased in all three MSDLs, whereas no significant changes were found in N61 in response to drought stress. Metabolome analysis identified six common drought-induced metabolites in all of the investigated genotypes. However, four metabolites (adenine, gamma aminobutyric acid, histidine, and putrescine) each specifically accumulated in an MSDL in response to drought stress, suggesting that these metabolites are important for MSDL drought resistance. In conclusion, MNH5 and MSD345 showed better adaptive responses to drought stress than MSD53 and N61, suggesting that these two MSDLs could be explored for breeding drought-resistant wheat lines.
State of lipid peroxidation and endogenous intoxication under non-small-cell lung cancer

Background: The problems of optimizing the methods of diagnosis and predicting the course of lung cancer occupying a leading position in the structure of cancer are still relevant. Aims and Objectives: To establish the patterns of changes in the parameters of endogenous intoxication and lipid peroxidation processes in the saliva of patients with non-small-cell lung cancer (NSCLC) depending on the histological type of a tumor. Materials and Methods: A total of 505 people took part in the casecontrol study: The main group (NSCLC, n = 290) and the control one (healthy, n = 215). All participants were questioned and underwent the biochemical examination of saliva and histological verification of the diagnosis. The parameters of endogenous intoxication and lipid peroxidation were determined spectrophotometrically. Results: The results of the study support the hypothesis of association of endogenous intoxication and lipid peroxidation processes with the development of NSCLC. It was shown that against the background of NSCLC; the level of primary lipid peroxidation products decreases. Thereat, the content of triene conjugates and Schiff bases, as well as the MM 280/254 nm distribution coefficient, increases. The growth of these indicators with an increase in the size of the tumor was noted. The differences due to the histological type of NSCLC have been identified. Conclusion: Thus, with squamous cell NSCLC, a higher level of secondary lipid peroxidation products was noted. The presence of distant metastases in lungs significantly contributes to changes in indicators of endogenous intoxication and lipid peroxidation in case of adenocarcinoma.
Agriculture Sector Growth and Inflation in Ethiopia: Evidence from Autoregressive Distributed Lag Model

There is cross country difference about the relationship between economic growth and inflation. Although the issue is the most researched topic, limited studies were undertaken at sectoral level, such as the relationship between inflation and agriculture sector growth. Therefore, this study examines the effect of inflation on agriculture sector growth of Ethiopia from 1980-2018 using Autoregressive Distributed Lag model. Inflation has negative and significant long-run relation with agriculture sector growth suggesting that inflation is harmful to agriculture sector growth than stimulating it. Other regressors such as total factors productivity, arable land and labour force growth have positive and significant long-run relationship with agriculture growth. In the short run, the growth of agriculture sector has positive and significant relationship with its lagged value, capital, labour force, factors productivity, inflation and exchange rate. Thus, to increase the growth of agriculture sector, government should moderate inflation using prudent monetary and fiscal policy. It should also monitor the efficacy and suitability of agriculture investment to countries context. As land is fixed input, intensive agriculture and productivity enhancing technologies should be applied. Increasing labour skill through training could also increase agriculture output.
Timing of mass spawning in corals: potential influence of the coincidence of lunar factors and associated changes in atmospheric pressure from northern and southern hemisphere case studies

Abstract Synchronised multispecies mass spawning events are striking features of reproduction in corals. This synchronous gamete release of thousands of animals over vast stretches of reef is thought to be cued by rhythms of the Moon. However, the mechanisms are not fully understood. We propose an explanation that may contribute to understanding this mechanism, that spawning is triggered by the coincidence of two factors, each in different lunar rhythms. We investigate this proposal in case studies using seven years of coral spawning data from two locations: Kochi, Japan and Lizard Island, Australia. Our calculations show that a feature in a lunar synodic rhythm (the third quarter) will synchronise with a feature in a lunar non-synodic rhythm (the zero declination) usually once, although occasionally twice in a year. Supported by data on the date of spawning from the two locations, we suggest that this coincidence of lunar factors exerts an important influence on the timing of annual mass spawning in corals. This coincidence may be associated with low atmospheric pressure. Spawning at the time of the third lunar quarter may favour fertilisation success due to the reduced currents during neap tides associated with the lower gravitational pressure of the lunar quarters.
Drivers and consequences of customer participation into value co-creation: a field experiment

Purpose This paper aims to analyze value co-creation (VCC) in new product development from consumer’s perspective. It offers a holistic approach to consumers’ VCC behavior with its before (drivers) and after (consequences) stages. Design/methodology/approach Three consecutive studies are carried out to test the hypotheses examining the antecedents and results of co-creation behavior, as well as the behavior itself in a new headphones design context. The experimental data have been collected from 934 university students within a period of six months. Findings Findings suggest that extraversion and openness to experience increase consumers’ willingness to participate in VCC. Celebrity endorsers and product category involvement also affect this tendency. When consumers display co-creation behavior, they intend to purchase the product to be co-created. However, they are especially keen to buy this co-created product when their contributions are embodied in it. Originality/value Previous studies focus on intentions, lacking a detailed analysis of actual VCC behavior. By shedding light on co-creation behavior with its before and after stages, this paper contributes to co-creation literature with a field experiment. Consumers’ co-creation behavior has been observed in the context of new product development, which is mostly occupied by business to business research. Therefore, the results also add to research on new product development in business to consumer contexts.
Leaching and residual activity of imidazolinone herbicides in lowland soils

Herbicides used in the Clearfield® rice (Oryza sativa L.) production system have a potential for leaching. This can result in contamination of underground water resources and cause injury to not tolerant crops that are sown in a succession and/or crop rotation. The objective of this study was to determine the leaching potential and the residual activity of the herbicides used in the Clearfield® rice system. The experiment was conducted over a period of two years and consisted of conducting a field test to be followed by two bioassays with a year of difference between their implementation. Initially an experiment was conducted in lowland area where it was planted the cultivar of rice ‘PUITA INTA CL’. Approximately one and two years thereafter, soil samples from each plot were collected at intervals of 5cm to a depth of 30cm (B factor) for the bioassay to evaluate persistence of herbicides. Factor A was composed of mixtures formulated of imazethapyr + imazapic (75 + 25g a.i. L-1), imazapyr + imazapic (525 + 175g a.i. kg-1) in two doses, imazethapyr (100g a.i. L-1) and treatment control without application. Basing on results, it was concluded that the mixtures imazethapyr + imazapic, imazapyr + imazapic and imazethapyr leached into the soil, reaching depths of up to 25cm in lowland soil. Imidazolinone herbicides used today in the irrigated rice Clearfield® system are persistent in soil, and their phytotoxic activity can be observed up to two years after application.
Analytical model for concrete cover separation of FRP strengthened RC beams with multiple steel bolts

In this paper, analytical models for concrete cover separation (CCS) of FRP strengthened reinforced concrete (RC) beams with multiple steel bolts were developed based on concrete tooth model for strengthened RC beams without anchors. The derivation of the models involved three major steps: (a) determination of the crack spacing (width of the concrete teeth); (b) determination of the pull‐out strength of steel bolt considering the effect of shear crack; and (c) determination of the peak load of FRP strengthened beams when CCS occurs based on the concrete tooth model. Validation test on five RC beams was conducted to investigate the effect of anchorage systems on the premature debonding of FRP strengthened RC beams. Results showed that steel bolts with enough embedding length can effectively suppress the initiation and propagation of CCS, thus improve the performance of FRP strengthened RC beams. Moreover, a database of FRP strengthened RC beams with mechanical fasteners (MFs) and failed in CCS or FRP fracture (FR) was assembled from the literature. The analytical predictions agreed well with the experimental results.
Effects of high-intensity interval training associated to microcurrent on localized adiposity: protocol of randomized clinical trial

Background: High-intensity interval training promotes body weight loss, while microcurrent electrical stimulation has therapeutic potential toreduce localized abdominal fat. However, there are no studies that have investigated the association of the two forms of intervention in reducinglocalized adiposity. Objectives: To verify the effects of high-intensity interval training, associated or not, with microcurrent therapy, in reducinglocalized abdominal fat. Methods: A randomized controlled clinical study will be conducted with 60 women aged 18 to 40 years, with localizedabdominal adiposity. Participants will be randomized into 3 groups: Control Group (without physiotherapeutic intervention), Exercise Group(high-intensity interval training for 30 minutes) and Exercise Group associated with Microcurrent (application of 30 minutes of microcurrent priorto high-intensity interval training). The intervention will take place twice a week for 5 weeks. The clinical outcomes evaluated and their respectivemeasuring instruments will be: body composition (bioimpedance scale and adipometry), anthropometric measurements (perimetry), level ofphysical activity (International Physical Activity Questionnaire - IPAQ, short version), quality of life (IWQol-Lite, short version), body satisfaction(Stunkard figure rating scale), degree of satisfaction with the performance of the intervention (questionnaire adapted by the researchers) andevaluation of the lumbopelvic complex. These outcomes will be measured in 4 moments: before the intervention, after the 5th and 10thintervention, and with a follow-up of 1 month. Discussion: A previous study has already shown the positive result of the association of moderateintensity exercise, associated with the previous application of microcurrent, in reducing localized abdominal adiposity. These findings raised thehypothesis that the association of this electrical therapy with high-intensity interval training may present positive results in the search for thereduction of abdominal fat, with the clinical advantage of enhancing the achieved results and/or reducing the time spent by the patient in therapy.
Broadleaf Weed Control in Safflower (Carthamus tinctorius) with Sulfonylurea Herbicides

Safflower (Carthamus tinctorius L. ‘Hartman’) in the rosette growth stage or early bolting stage tolerated thiameturon {3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino] carbonyl] amino] sulfonyl]-2-thiophenecarboxylic acid} at 5, 10, and 15 g ai/ha. Safflower also tolerated chlorsulfuron {2-chloro-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino] carbonyl] benzenesulfonamide} at 18 g/ha if safflower was taller than 15 cm at time of application. The fresh weight of above-ground biomass of common sunflower (Helianthus annuus L. #3 HELAN), treated at two plant sizes with thiameturon, was reduced more than 88%. Soil activity of thiameturon also reduced the seedling vigor of common sunflower, but thiameturon in soil was not as lethal to common sunflower as were foliar applications.
Morphometry, length-weight relationship and biology of Sepia aculeata (d'Orbigny, 1848) from Mumbai coast, India

Seventeen morphometric characters of Sepia aculeata of Mumbai coast have been studied and the relationships of morphometric characters with dorsal mantle length (DML) were established. The characters compared showed a fair to high degree of correlation ('r' 0.63-0.99). Number of arm suckers and shell rings were related with DML. The shell rings also showed high degree of correlation with DML ('r' 0.79-0.95). However, the relationship between arm suckers and DML was not so good ('r' 0.1-0.4). The length-weight relationship is described as W=0.1821336 L sub(2.801102). Food and feeding analysis confirm the carnivorous feeding behaviour of the species. Mature females found in all months indicate that it has prolonged spawning season with two peaks, september and march-april. Absolute fecundity ranged from 214 to 4143 eggs.
Mediating effect of cognitive load in song learning with visually presented lyrics

The purpose of this study was to ascertain whether seeing the lyrics while learning a difficult song aurally induces less cognitive load in learners compared to not seeing the lyrics, leading to better recall accuracy of the learned song. Cognitive load was assessed through a reaction time measure based on a dual-task paradigm. Recall accuracy of the learned song was measured regarding lyrics, pitches, and rhythm. Thirty-six non-music majors individually learned two songs through prerecorded aural instruction; for one song they saw the lyrics and for the other song they did not see the lyrics. The presentation order of instructional condition and song were counterbalanced. Results showed instructional condition affected cognitive load but not recall accuracy. A path analysis revealed a mediating effect of cognitive load regarding lyrics and rhythm, suggesting seeing the lyrics indirectly increases recall accuracy of lyrics and rhythm through its positive effect on cognitive load. Given limited instructional time, several strategies should be considered to prevent learners from experiencing cognitive overload while learning a difficult song aurally. Showing the lyrics of the difficult song could be one strategy for that purpose, at least for young adults with low levels of musical expertise.
Growth Pattern, Mortality and Exploitation Rate of the Giant African Threadfin, Polydactylus quadrifilis (Cuvier, 1829) from Ebrié Lagoon (Potou Sector, Côte d’Ivoire)

The study evaluated some population parameters of Polydactylus quadrifilis within Ebrié lagoon (Potou sector). Samples were obtained using artisanal gillnet fishery from April 2004 to March 2006. A total of 741 individuals of P. quadrifilis ranged from 11 to 70 cm were examined. Population parameters were estimated where asymptotic length (L∞) was found 60 cm, growth rate (K) 0.33 per year, the longevity (T max) 9.09 years, and growth performance index (Φ′) 3.06. The length at first capture (Lc50 = 10.60 cm) was lower than the length at first maturity (Lm50 = 40 cm). Total mortality rate (Z) was calculated as 1.10 per year including natural mortality and fishing mortality. The exploitation rate (E=0.36) was found to be less than the maximum exploitation rate (E max = 0.44) and indicated that P. quadrifilis is not overexploited. The current exploitation rate should be maintained by sustainable fisheries measures including monitoring of fishing effort.

Introduction: Soft tissue expansion with percutaneous distensible expanders gained popularity for reconstructive surgery in the face and neck. Purpose: The aim of this study was to compare by using tissue expander with autogenous bone graft versus autogenous bone graft only for reconstruction of anterior region of the mandible. Materials and Methods: The study included 20 patients with anterior mandibular bony defects. Patients were randomly divided into 2 groups. Patients in group I, underwent mandibular augmentation with tissue expander followed by autogenous bone graft. While in group II, autogenous bone graft was used only. Preoperative and six months postoperatively; computed tomography and lateral cephalometric views had been performed in all cases in both groups. Cephalometric points, landmarks and measurements are recoded to compare between both groups regarding pre and post-operative results. Results: In both groups, comparison between pre and post-operative variables showed; significant difference of the mandible in the anteroposterior direction and non-significant change in the vertical measurements. Soft tissue profile showed significant increase in the position of the upper and lower lip and soft tissue pogonion. While, the nasolabial angle, the pronasale, and soft tissue A point showed non-significant changes. Comparison between both groups showed significant improvement of the horizontal direction of the mandible, mandibular length and soft tissue profile in group I than group II. P-value (> 0.05) was considered non-significant. Conclusion: Tissue expansion has become a popular procedure in the reconstruction of face and neck lesions.
