Social workers’ perceptions of their peers’ unprofessional behavior

Summary This article explores social workers’ perceptions of their colleagues’ professional mistakes, and the influences of those opinions. Vignettes in a factorial survey helped to determine whether certain variables related to the social worker or the situation influenced the perception of others’ professional errors and ethical violations. The changed variables included personal characteristics of the offending social worker such as perceived race, gender, and sexual orientation of the social worker, and characteristics of the situation, such as the length of time involved in unprofessional behavior. Findings Licensed social workers in six U.S. states (n = 5596) read vignettes based on real cases brought before licensing boards (n = 22,127) and assigned levels of seriousness and importance to discipline. The vignettes rated most highly involved perceived harm to a client or other vulnerable individual. Those on the lower end of seriousness and importance to discipline were those violations against the profession of social work. Analysis of changed variables indicated respondents’ ratings were influenced by several situational factors, but not by personal characteristics of the social worker involved in the vignette. Applications Our findings provide some insight into the decision-making factors important to social workers. The results may be helpful to licensing boards considering the contextual factors of unprofessional behavior and whether to discipline certain actions.
Investigating University Student’s Acceptance of Information and Communication Technology: Applying the Technology Acceptance Model

Building on the technology acceptance model (TAM), this study examines university student’s acceptance of information and communication technology (ICT) as a learning resource outside of the classroom. With the aim of looking more deeply into this subject, the study applied the technology acceptance model to recognize the effect of perceived usefulness on the student’s actual use of ICT with the existence of perceived usefulness as a moderator variable. Data were collected from 376 students from Duhok Polytechnic University in the Kurdistan Region of Iraq using a questionnaire survey consisting of 15 items developed based on the related literature. The results support that both perceived ease of use and perceived usefulness are key determinants of student’s actual use of ICT as a learning resource, and the relationship between perceived ease of use and actual use is moderated by perceived usefulness. Based on the findings, conclusions, implications, limitations, and an outlook for future studies were made. The originality of this study stems from the use of perceived usefulness as a moderator on the relationship between perceived ease of use and actual use of ICT among university students.
Interaction Devices as Assistive Technology: Current Practices about Evaluation Methodologies

ABSTRACT A significant challenge on Assistive Technology (AT) relies on the interaction devices’ evaluation phase. Generally, the gap between users and devices is revealed during the use. This fact highlights the relevance of discussing these barriers early in the design process, mainly, in the evaluation phase. This article explores current practices of evaluation methodologies for AT interaction devices, both considering the usage of computers and TV-sets. Two research stages were performed to achieve this objective: a systematic mapping study of AT evaluation methodologies, and field research in Portugal, with experts in AT Evaluation and end-users. This last step was done through semi-structured interviews, whose results passed by a content analysis process. The findings from these researches suggest that there are vital dimensions that should be addressed when evaluating AT. Firstly, qualification issues remain most important, especially concerning to the developers’ awareness of end-user needs as, for example, difficulty in computer access. Other important points are the economic problems, involved in the acquisition of AT interaction devices, and the emotional issues related to using these devices. Finally, the article concludes with a discussion on directions for evaluation methodologies of AT interaction devices.
Porous Cotton-derived Carbon: Synthesis, Microstructure and Supercapacitive Performance

Biomass materials were widely used to synthesize porous carbon for energy storages considering the simple preparation method and wide availability of raw materials. Herein, we prepared nitrogen doped porous carbon from natural cotton via a simple one-step eco-friendly method. The cotton-derived carbon material delivers a maximum specific surface area of 480 m/g and a high nitrogen content of 6.84% at the carbonization temperature of 750°C. The obtained material shows excellent performance when used as supercapacitor electrode materials, which exhibits a maximal specific capacitance of 252 F/g at 1 A/g in 1 mol/L H2SO4 electrolyte and retains 94% of the capacitance after 10,000 cycles at 15 A/g. The good performance of the low-cost carbon electrode made from cotton provides a potential application for electrochemical capacitors.

Presence of antioxidants and nitric-oxide precursors in Mimosa pudica extract

Blood pressure lowering effect of Mimosa pudica induced by dieresis was reported earlier. As a diuretic it enhances urine outflow, decreases plasma volume, venous return; and thereby, reduce blood pressure. Besides the diuretic agent, some other blood pressure lowering substance may also be present in Mimosa pudica. Present study was undertaken to reveal the presence of antioxidants and nitrite in Mimosa pudica extract, which may help to reduce blood pressure. Methanolic extract of Mimosa pudica (using 80% methanol) was lyophilised to obtain dried Mimosa pudica Extract (MPE). For Total phenolic content estimation Folin’s method and for estimation of flavonoids, Aluminium chloride method were followed. The radical scavenging and superoxide anion radical scavenging activity were measured following standardised methods. Nitrite content of MPE at different dilutions (10-100 µl in methanol) was measured following standardised procedure keeping sodium nitrite as the standard. Present study noted presence of favonoids and phenolic compounds and also noted antioxidant property in the aforesaid extract that exhibited DPPH+ and superoxide scavenging activities. Besides that, this study also revealed formation of nitrites in the extract of Mimosa pudica in a dose dependent manner. Nitrite is the precursor of nitric oxide (NO). NO is a potent vasodilator that decreases blood pressure. Present study indicated the presence of both antioxidants and nitrites in Mimosa pudica extract; both of which have blood pressure lowering properties indicating it as a blood pressure lowering agent; and helpful in the maintenance of vascular health.
Nitrogen-Modified Graphdiyne as a Promising Membrane for Helium Separation: First-Principles and Molecular Dynamics Simulations

The He separation performance of the N-modified graphdiyne monolayer (N-GDY) was studied by using both the first-principles density functional theory (DFT) and molecular dynamics (MD) simulations. The high cohesive energy of 7.24 eV/atom confirmed the strong stability of N-GDY for a gas separation membrane. Based on the calculations, the N-GDY membrane was found to exhibit extremely high He permeance (4.8 ×10-3 mol/m2·s·Pa at 100 K) and selectivities of He/H2O, He/Ar, He/N2, He/CO, He/CO2, and He/CH4 (102~1012 at 300 K). Therefore, N-GDY should be a good candidate for He separation from natural gas.
Dynamic Characteristics of the Bouc–Wen Nonlinear Isolation System

The Bouc–Wen nonlinear hysteretic model has many control parameters, which has been widely used in the field of seismic isolation. The isolation layer is the most important part of the isolation system, which can be effectively simulated by the Bouc–Wen model, and the isolation system can reflect different dynamic characteristics under different control parameters. Therefore, this paper mainly studies and analyzes the nonlinear dynamic characteristics of the isolation system under different influence factors based on the incremental harmonic balance method, which can provide the basis for the dynamic design of the isolation system.
PHYTOCHEMICAL, ANTI-INFLAMMATORY, ANTIOXIDANT, CYTOTOXIC AND ANTIBACTERIAL STUDY OF CAPPARIS CARTILAGINEA DECNEFROM YEMEN

Objective: To investigate phytochemicals and biological activities of Capparis cartilaginea extracts.Methods: The methanolic extracts of leaves, stem and twigs of C. cartilaginea were screened for their phytochemicals. The essential oil of the leaves was hydrodistilled by a Clevenger apparatus and analyzed by gas chromatography-mass spectrometry (GC-MS). The leaves extract of C. cartilaginea was evaluated for its anti-inflammatory effect, using formalin-induced paw edema. The leaves, stem and twig extracts were assessed for their antioxidant activity, using free radical scavenging assay, cytotoxic activity, using 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay and antibacterial activity, using the microdilution method.Results: All extracts of C. cartilaginea contained alkaloids, carbohydrates, protein, coumarin, phytosterols, bitter principles, phenols and tannins. The essential oil of the leaves was mainly composed of isopropyl isothiocyanate (69.4%), butane,1-isothiocyanate (26.97%) and isobutyl isothiocyanate (3.26%). The leaves extract at doses of 200 and 400 mg/kg, significantly inhibited paw edema at the 3rd h (49.1%, 54.0%, respectively) and this effect was comparable to that of diclofenac (58.87%). The leaves extract showed the highest antioxidant activity with IC50 value of 91.71 µg/ml. The twigs extract exhibited the highest cytotoxic activity against human lung carcinoma (A549) with IC50 of 57.5 µg/ml. The leaves and stem extracts exhibited antibacterial activity against Staphylococcus aureus with minimum inhibitory concentration (MIC) of 5.0 mg/ml. Conclusion: The leaves extract of C. cartilaginea is a potential source of bioactive compounds that could have a role in anti-inflammation. Twigs extract of the C. cartilaginea possesses a potential cytotoxic effect on human lung cell line.
History of Acute Promyelocytic Leukemia

In this article, we discuss the history of acute promyelocytic leukemia (APL) from the pre-therapeutic era, which began after its recognition by Hillestad in 1947 as a nosological entity, to the present day. It is a paradigmatic history that has transformed the “most malignant leukemia form” into the most curable one. The identification of a balanced reciprocal translocation between chromosomes 15 and 17, resulting in fusion between the promyelocytic leukemia gene and the retinoic acid receptor alpha, has been crucial in understanding the mechanisms of leukemogenesis, and responsible for the peculiar response to targeted therapy with all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). We review the milestones that marked successive therapeutic advances, beginning with the introduction of the first successful chemotherapy in the early 1970s, followed by a subsequent incorporation of ATRA and ATO in the late 1980s and early 1990s which have revolutionized the treatment of this disease. Over the past two decades, treatment optimization has relied on the combination of ATRA, ATO, and chemotherapy according to risk-adapted approaches, which together with improvements in supportive therapy have paved the way for cure for most patients with APL.
Once upon a time in the far south: Influence of local drivers and functional traits on plant invasion in the harsh sub-Antarctic islands

Aim Here, we aim to: (i) investigate the local effect of environmental and human-related factors on alien plant invasion in sub-Antarctic islands; (ii) explore the relationship between alien species features and their dependence on anthropogenic propagule pressure; and (iii) unravel key traits conferring invasiveness in the sub-Antarctic. Location Possession Island, Crozet archipelago (French sub-Antarctic islands). Taxon Non-native vascular plants (Poaceae, Caryophyllaceae, Juncaceae). Methods Single-species distribution models were used to explore the effect of high-resolution topoclimatic and human-related variables on the occurrence of six of the most aggressive alien plants colonizing French sub-Antarctic islands. Furthermore, the interaction between alien species traits and their response to anthropogenic propagule pressure was analysed by means of a multi-species distribution model. This allowed identifying the features of species that were associated to low dependence on human-assisted introductions, and were thus potentially more invasive. Results We observed two main invasion patterns: low-spread species strongly dependent on anthropogenic propagule pressure and high-spread species limited mainly by harsh climatic conditions. Differences in invasiveness across species mostly related to their residence time, life history and plant height, with older introductions, perennial and low-stature species being more invasive. Main conclusions The availability of high-resolution data improved our understanding of the role of environmental and human-related factors in driving alien species distribution on sub-Antarctic islands. At the same time, the identification of alien species features conferring invasiveness may help anticipating future problematic invasions.
Hydrothermal Carbonization of Oil Palm Pressed Fiber: Effect of Reaction Parameters on Product Characteristics

This work focused on the hydrothermal carbonization (HTC) of oil palm pressed fiber for the production of valuable products, over the reaction temperature (140 to 200 °C), time (1 to 4 h), and biomass to water content (BTW) (1:5 to 1:15). Reaction temperature was a vital key parameter on fuel properties of hydrochar. The combustibility of hydrochar reflected by fuel ratio increased from 0.42 at 140 °C to 0.54 at 200 °C. O/C and H/C atomic ratio decreased from 0.56 and 1.54 to 0.37 and 1.28, respectively, which corresponded to an increase in the estimated HHV from 21.0 to 24.6 MJ/kg. Hydrochar yield decreased from 78.4 to 61.7%. These phenomena were associated with hydrolysis, dehydration, decarboxylation, aromatization, and recondensation reactions. The reaction time and BTW affected slightly the yield and fuel properties of hydrochar. The valuable dissolved organic chemical species in the obtained liquid fraction were furfuryl alcohol, furfural, hydroxymethylfurfural, acetic acid, propionic acid, lactic acid, and formic acid with the maximum yields of 6.95, 2.05, 0.64, 6.91, 4.75, 4.11 and 2.64 wt. % dry raw material, respectively.
Low-cost heuristics for matrix bandwidth reduction combined with a Hill-Climbing strategy

This paper studies heuristics for the bandwidth reduction of large-scale matrices in serial computations. Bandwidth optimization is a demanding subject for a large number of scientific and engineering applications. A heuristic for bandwidth reduction labels the rows and columns of a given sparse matrix. The algorithm arranges entries with a nonzero coefficient as close to the main diagonal as possible. This paper modifies an ant colony hyper-heuristic approach to generate expert-level heuristics for bandwidth reduction combined with a Hill-Climbing strategy when applied to matrices arising from specific application areas. Specifically, this paper uses low-cost state-of-the-art heuristics for bandwidth reduction in tandem with a Hill-Climbing procedure. The results yielded on a wide-ranging set of standard benchmark matrices showed that the proposed strategy outperformed low-cost state-of-the-art heuristics for bandwidth reduction when applied to matrices with symmetric sparsity patterns.

Neuromuscular Inhibitory Effects of the Aqueous and Methanol Extracts of Alchornea laxiflora in Adult Albino Mice

The study investigated the median lethal dose and the effects of the aqueous and methanol extracts of Alchornea laxiflora in two neurobehavioural models of motor coordination, the traction (grip strength) and rotarod tests. This was with a view to providing information on the acute toxicity and the effects of the plant extracts on neuromuscular function. The LD50 for the aqueous and methanol extracts of A. laxiflora in the oral route was > 1600 mg/kg respectively, and found to be safe in animals. However, the LD50 (i.p.), was found to be 400 mg/kg for the methanol extract, which was relatively toxic and > 1600 mg/kg for the aqueous extract. Mice of both sexes (n=6) weighing 18 – 22 g were used for the study, which were randomized into control and test groups, which summed up to seven (VII) groups. The control group (1) received 10 % Tween 80 (vehicle), 0.1 ml/10 g mouse while the test groups (II,III,IV,V,VI) were administered graded doses (100, 200, 400, 800, 1600 mg/kg, p.o.) of the extracts. The standard group (VII) received Diazepam (4 and 10 mg/kg, i.p.). The animals were individually observed for fall off time from the revolving horizontal bar in the rotarod test and for the loss of muscle grip or grip strength in the traction test. They were appropriately scored after observation at intervals of 30, 60, 90, 120 and 150 min post intra-peritoneal and oral administrations of vehicle, extracts or drugs respectively. The results showed that A. laxiflora possesses significant (P ≤ 0.05) inhibitory effect on neuromuscular function due to the increase in the time taken for the animals to grasp the horizontally stretched wire with the hind limbs in the traction test. However, the extracts did not demonstrate any significant (P > 0.05) effects on the fall off time in the rotarod performance test. The study concluded that A. laxiflora possesses skeletal muscle relaxant activity in mice.
