Modern Thoughtography: Mind Interaction at a distance with digital camera sensors: a pilot study

The aim of this pilot study was to determine the possibility of mentally producing, from a geographical distance, predefined images on modern digital sensors of professional commercial photographic cameras, and to do it sufficiently well for the images to be recognized by a special software. Three participants experienced in distant mind-matter interaction techniques took part in a total of 49 trials. In 6 out of 49 trials (12.2%) the value of the Structural Similarity Index of the target image chosen by the participant for the distant mental influence trial on the camera’s sensor was greater than that obtained when the target was different.Although still preliminary, these results suggest that it may be possible to use modern professional cameras to study the effects of distant mind-matter interactions.
Preanalytical variables and its impact on total quality management of clinical biochemistry laboratory- A tertiary referral rural hospital study

Introduction: Advances in science and Technology have led to transformation of laboratory diagnostics from manual, cumbersome testing methods to fully automated science, ensuring accuracy and speed. Quality is the core issue for all laboratories and this requires total quality management in the laboratory process in the preanalytical, analytical and post analytical phases. Objectives: To study and evaluate the types, frequency and magnitude of errors in our tertiary health care clinical Biochemistry Laboratory in the preanalytical testing process and its overall impact on Total Quality Management System of our laboratory. Materials and Methods: A prospective observational study, samples received for analysis between Jan 2015 to Dec 2015 in the clinical biochemistry section was evaluated for various preanalytical errors. We evaluated the frequency and types of preanalytical errors found in our laboratory by monitoring specimes requested for laboratory analyses from both inpatient and outpatient divisions and statistically analyzed. Results and Discussion: Of the total 1,38,275 analytical requests, 6446 (4.66%) samples were rejected due to various errors in preanalytical variables. For the inpatient samples, preanalytical error rate was 4.20% (4107 samples), the preanalytical variable with highest frequency of occurrence was specimen hemolysis/ Lipemic sample (1.00%) 980 samples. For the outpatient sample preanalytical error rate was 5.75% (2339). The variable with highest frequency was requisitions with incomplete patient treating physician information 1.37% (559). Preanalytical errors in laboratories are very common and play a very important role in patient care and treatment. Lipemic/hemolytic samples are known to affect the parameter to be analysed and incomplete patient information leads to error in reporting the patient’s results, which means the post analytical error becomes unavoidable and incomplete treating physician information leads to delayed reporting
ETHICAL CLIMATE, ETHICAL BEHAVIOR AND PROFESSIONAL VALUES AS PERCEIVED BY STAFF NURSES' AT TWO DIFFERENTHOSPITALS

ETHICAL CLIMATE, ETHICAL BEHAVIOR AND PROFESSIONAL VALUES AS PERCEIVED BY STAFF NURSES’ AT TWO DIFFERENT HOSPITALS Background: Assessment of staff nurses' perception regarding ethical climate, ethical behavior and professional values can help nursing administrators to discover more successful strategies toward improving their well-being and decreasing work-related stress. Aim: The present study was conducted to investigate the relationship among ethical climate, ethical behavior and professional values as perceived by staff nurses at two different hospitals. Design: Descriptive correlation for comparative design was utilized to achieve the aim of the present study. Setting: The present study was conducted at two different health care (private and teaching) sectors. Subjects: Convenient sample of staff nurses (n=194) who agreed to share in this study. They were divided as follows: (n=89) from private hospital and (n=105) from teaching hospital. Tools: Data were collected using three questionnaires: ethical climate (26 items), ethical behavior (12 items) and nurses' professional value (26 items). Results: The study illustrated that there was no statistically significant difference among total perception of staff nurses' regarding ethical climate, ethical behavior and professional values at private and teaching hospitals (p=0.16, p=0.34 and p=0.28) respectively. Staff nurses had high mean % regarding their perception of professional values (87.66%), ethical behavior (86.74%), and ethical climate (83.32%). There was a strong positive statistically significant relation between total perception of ethical climate, ethical behavior and professional values (p=0.00). Finally, a strong positive statistically significant relation among total staff nurse's perception of ethical behavior and professional values (p = 0.00). Conclusion: There were no statistically significant deference among total perception of staff nurses toward ethical climate, ethical behavior and professional values at private and teaching hospitals. There was a strong positive statistically significant relation between total perception of ethical climate, ethical behavior and professional values. Recommendations: Nursing administrators should support achievement of ethical climate, nurses should update their knowledge regarding professional nursing ethics, through engaging periodically in workshop and training programs and nursing educator should integrate ethical practice into nursing curricula.
Resolving Ambiguity Using Word Embeddings for Personalized Information Retrieval in Folksonomy Systems

The diversity and high volume of available information on the web make data retrieval a serious challenge in this environment. On the other hand, obtaining user satisfaction is difficult, which is one of the main challenges of data retrieval systems. Depending on their information about interests and needs for the same keyword, different people expect different responses from Information Retrieval (IR) systems. Achieving this goal requires an effective method to retrieve information. Personalized Information Retrieval (PIR) is an effective method to achieve this goal which is considered by researchers today. Folksonomy is the process that allows users to tag in a specific domain of information in a social environment (tags are accessible to other users). Folksonomy systems are made collaborative tagging systems. Due to the large volume and variety of tags produced, resolving ambiguity is a severe challenge in these systems. In recent years, word embedding methods have been considered by researchers as a successful method to fix the ambiguity of texts. This study proposes a model which, in addition to using word embedding methods to remove tag ambiguity, provides search results in a personalized approach by fixing ambiguity and sentiment analysis combination tailored to users' interests. In this research, different models of word embeddings were applied. The experiments' results show that after applying the fixing ambiguity, the mean accuracy criterion improved by 1.93% and the mean MRR (Mean Reciprocal Rank) by 0.38%.
High-pressure high-temperature behaviour of the lanthanide metals

The high-pressure behaviour of the lanthanide series of metals has been the subject of study since the work of Percy Bridgman in the 1940s. Differences in said behaviour between the different lanthanide metals are attributed to the increasing occupation of the 4f electron shell as Z increases. Upon compression, or as Z decreases, the trivalent lanthanides (La to Lu, excluding Eu and Yb) undergo a common phase transformation sequence through various close packed structures: hcp → Sm-type (the structure adopted by samarium at ambient conditions) → dhcp → fcc → distorted fcc (d-fcc). Upon further compression, the lanthanide metals experience a first order transition to a “volume collapsed” phase. Many studies have focused on the low-Z members of the series, since the various phase transitions occur at much lower pressure where it is comparatively easy to collect high quality data. By contrast, the other members of the series have received comparability little attention, and there are even fewer reports of the structural behaviour of the lanthanide metals at high pressure and high temperature. This thesis contains the results of angle-dispersive x-ray powder diffraction experiments at high pressure and high temperature of the various members of the lanthanide metals. Ce has been the subject of many previous studies, but a systematic x-ray diffraction study of the fcc/d-fcc phase boundary has never been attempted. Furthermore, the location in P -T space of the high temperature fcc/bct/d-fcc triple point has only been inferred, due to the lack of data on the fcc/bct phase boundary at high temperature. The high-pressure high-temperature phase diagram of Ce is presented and discussed. La is unique amongst the lanthanide metals due to its empty 4f shell at ambient conditions. Despite this, La undergoes the common lanthanide transformation sequence up to the d-fcc phase, after which it undergoes a re-entrant transition back to the fcc phase at 60 GPa. The diffraction peaks of d-fcc La are shown in this thesis to undergo changes in intensity upon compression, indicating a
The Utilization of the Valid Rubric to Improve High School Students' Real-world Problem-solving Skills in STEM Education

: Nowadays, students confront challenges with high-level technology. Thus, they need to learn how they can appropriately use technology. Students learn every subject, such as science, technology, engineering, and mathematics at school separately. Then, when they must find a solution that requires to combine two different subject matters, such as engineering and mathematics, they have difficulties to solve the problem because they do not know how to combine two subjects as one discipline. If a school provides Science Technology Engineering and Mathematics (STEM) education in their curriculum, students will learn how to apply their knowledge to solve the problem. Besides, teachers still use the conventional method to teach students and separate every subject as one independent subject. To analyze students' problem- solving skills, teachers use a rubric to assess students' ability in problem-solving. Even though the teachers use a rubric, the rubric is probably not valid because the rubric cannot analyze students' performance continuously. This research explains the usage of a valid rubric to improve students' problem -solving skills in STEM education. The researcher does a comprehensive literature review as a research method by using more than fifteen sources about STEM education, problem-solving, and a valid rubric of problem- solving skills in the results of this study indicate that students can improve their real -world problem- solving skills in STEM education after they getting feedback based on the proposed rubric.
Emerging Trends and Thematic Evolution of Breast Cancer: Knowledge Mapping and Co-Word Analysis

Background One of the requirements for scientists and researchers to enter any field of science is to have a comprehensive and accurate understanding of that discipline. Objective This study aims to draw a science map, provide structural analysis, explore the evolution, and determine new trends in research articles published in the field of breast cancer. Methods This study comprised a descriptive survey with a scientometric approach. Data were collected from MEDLINE using a search strategy based on Medical Subject Heading (MeSH) terms. This study used science mapping, which provides a visual representation and a longitudinal evolution of possible interrelations between scientific areas, documents, or authors, thus reflecting the cognitive architecture of science mapping. For this scientometric evaluation of the topic of breast cancer research, a very long period was considered for data collection. Moreover, due to the availability of numerous publications in the database, the assessment was divided into three different periods ranging from 1988 to 2020. Results A total of 12,577 records related to scientometric studies were extracted. The field of breast cancer research demonstrated three diagrams containing the most relevant themes for the three chronological periods evaluated. Each diagram was plotted based on the centrality and density linked to each research topic. The research output in the field was observed to revolve around 8 areas or themes: radiation injury, cardiovascular disease, fibroadenoma, antineoplastic agent, estrogen antagonistic, immunohistochemistry, soybean, and epitopes, each represented with different colors. Conclusions In the strategic diagrams, the themes were both well developed and important for the structuring of a research field. The first quadrant comprised motor themes of the specialty, which present strong centrality and high density (eg, corticosteroid antineoplastic age, stem cell, T-lymphocyte, protein tyrosine kinase, dietary, and phosphatidyl inositol-3-kinase). In the second quadrant of diagram, themes have well-developed internal ties but unimportant external ties, as they are of only marginal importance for the field. These themes are very specialized and peripheral (eg, DNA-binding). In the third quadrant, themes are both weakly developed and marginal. The themes in this quadrant have low density and centrality and mainly represent either emerging or declining themes (eg, ovarian neoplasm). Themes in the fourth quadrant of the strategic diagram are considered important for a research field but are not fully developed. This quadrant contains transversal and general, basic themes (eg, immunohistochemistry). Scientometric analysis of breast cancer research can be regarded as a roadmap for future research and policymaking for this important field.
Factors Affecting Behavioural Intentions in the Use of Mobile Learning in Higher Education

The technological revolution in the recent era is adding up means of learning. The launch of 3G/4G technologies supplementing with the latest applications and software have made mobile devices an effective medium for learning. The portable devices are facilitating the newest trends of learning such as e-learning and online learning. This study aimed to explore factors affecting students’ behavioural intentions regarding the use mobile learning and to investigate the moderating role of age, gender and programs of studies in the use of mobile learning at higher education level. Data were collected from 45 students through a questionnaire. Statistical techniques like frequencies, mean, correlation coefficient, t-test and one-way ANOVA were used to analyze data. It was concluded that all respondents possessed behavioural intentions to learn through mobile devices. There was no significant difference between the behavioural intentions of male and female respondents for using mobile learning. No significant difference was observed in behavioural intensions of respondents from different age groups and respondents enrolled in different programs to use mobile learning. It is recommended that management of higher education may design and implement the use of mobile devices in learning at higher education.
Colostrum avoidance and associated factors in Ethiopia: A systematic review and meta-analysis

Background: Colostrum is the first milk produced by the mammary glands during the second half of pregnancy for a few days (3-4) after birth. However, colostrum is a normative standard for infants’ complete form of nutrition, most mothers' giving prelacteal food such as honey, butter, sugar water, and plain water instead of colostrum to their newborn. In Ethiopia, colostrum was seen as abnormal milk causing abdominal problems, and to mitigate this problem most mothers were discarding the portion of the colostrum. Although studies have been conducted on colostrum avoidance and associated factors in Ethiopia, their report was inconsistent regarding the prevalence and associated factors. The main aim of this systematic review and meta-analysis was to estimate the pooled prevalence of colostrum avoidance and associated factors in Ethiopia.Methods: In this systematic review and meta-analysis databases such as Google, Google Scholar, PubMed/Medline, Science Direct, and Hinari were searched. We found a total of 327 records, of which 292 records were excluded due to duplication and unrelated to our objective. Finally, 35 studies were included in this systematic review and meta-analysis. The data were extracted in Microsoft Excel format and exported to STATA Version 14.0 statistical software for analysis. Heterogeneity was checked by the I2 test. A random-effect meta-analysis model was used to estimate the pooled prevalence of colostrum avoidance and associated factors. Egger’s weighted regression and Begg’s rank correlation test were used to assess publication bias. Result: This review revealed that the pooled prevalence of colostrum avoidance in Ethiopia was 20.5% (95% CI; 16.46, 24.45). Ante-natal care (ANC) visits [OR= 0.274 (95% CI; 0.175, 0.428)], place of delivery [OR= 3.8 (95% CI; 2.9, 4.9)], breastfed counselling [OR= 0.261(95% CI; 0.147 - 0.462), timely initiation of breast feeding [OR = 3.8 (95% CI; 1.9, 7.4)] and prelacteal feeding [OR= 5.77 (95% CI; 4.03- 8.22)] were significant factors for colostrum avoidance. Conclusion: This meta-analysis showed that one of five mothers discarded colostrum in Ethiopia. Colostrum avoidance was higher in rural mothers than in urban mothers. Strengthening ANC visits, institutional delivery, breastfed counseling, early initiation of breastfeeding, and avoidance of prelacteal feeding are recommended interventions to reduce colostrum avoidance in Ethiopia. Furthermore, promoting the health benefit of colostrum and its nutritional value also emphasizes to improving colostrum feeding in the community.
Is Serum Vasohibin 1 Level Associated With the Development of Nephropathy in Diabetic Patients?

Background: Glomerular filtration surface area and glomerular filtration rate (GFR) are increased in patients with diabetic nephropathy, especially in the early phase of the disease. Glomerular neoangiogenesis contributes to this increased GFR. Increased GFR is associated with glomerular neoangiogenesis. Vasohibin-1 is an inhibitor of neoangiogenesis. The aim of this study is to evaluate serum vasohibin-1 levels of diabetic patients with and without diabetic nephropathy (DN). Methods: One hundred and five diabetic patients and 39 healthy controls matched for age and gender were included in the study. Diabetic patients with eGFR<60 ml/min/1,73m2 and/or those who had persistent proteinuria (>200 mg/gr) measured by urine protein/creatinine ratio (UP/C) were diagnosed as overt diabetic nephropathy (DN) if they haven’t any other known kidney diseases. Serum vasohibin-1 levels were measured by ELISA. Serum creatinine, eGFR, UP/C and vasohibin-1 levels were recorded.Results: Thirty-four percent of diabetic patients had DN. Systolic blood pressure and UP/C were higher in diabetic patients than healthy controls and age, sex, eGFR were similar. Diabetic patients have nonsignificantly lower serum vasohibin-1 levels than healthy controls. Patients with DN had higher UP/C, lower eGFR and long-standing diabetes compared to diabetic patients without nephropathy. Serum vasohibin-1 levels were similar between diabetic patients with and without DN. There was no correlation between vasohibin-1 levels and eGFR or UP/C.Conclusions: In this study for the first time we showed that diabetic patients have slightly lower vasohibin-1 levels than healthy subjects but there was no difference between diabetic patients with and without nephropathy in terms of serum vasohibin levels. Because, vasohibin-1 exhibits its anti-angiogenetic properties by acting via autocrine-paracrine pathways; local vasohibin activity at the tissue level may be more important than the circulating levels.
Enhanced 5-µm emission in Tm,Tb: KPb2Br5 and Tm,Nd:KPb2Br5 for mid-infrared laser applications

We report on the 5 μm emission characteristics and energy transfer properties of Tb3+ doped KPb2Br5 and Nd3+ doped KPb2Br5 sensitized by Tm3+ ions. A series of co-doped samples of Tm,Tb: KPb2Br5 and Tm,Nd: KPb2Br5 samples were prepared from purified starting materials of PbBr2, KBr, and rare earth halides. Resonant excitation into the 3H6 → 3F4 absorption transition of Tm3+ at ~1760 nm resulted in an enhanced 5 μm emission from Tb3+ and Nd3+ ions in Tm,Tb: KPb2Br5 and Tm,Nd: KPb2Br5, respectively. The existence of energy transfer between Tm → Tb and Tm → Nd was further evidenced by the quenching of the emission decay times of the 3F4 → 3H6 transition of Tm3+ in doubly doped Tm,Tb: KPb2Br5 and Tm,Nd: KPb2Br5 compared to singly doped Tm: KPb2Br5.

Boosting Purchase Intention and Online Participation Through Passion

This study analyzes the role of passion in engaging users and how it affects purchase intention and participation in social commerce contexts. Based on marketing research, the engagement generation process is studied through the interactions among social presence,interactivity, enjoyment, sPassion, purchase intention and spread of sWOM. The results have empirically confirmed that social interactions and information exchange derived from the process boost user participation and the intention to purchase. At the core of the process, sPassion positively affects the spreading of sWOM. The introduction of the new concept sPassion brings new challenges and opportunities to marketing research, helping to develop the concept of engagement and furthering research on WOM valence. Knowing how sPassion is formed and what factors are key to its creation enable companies to understand the necessary steps to enhance user participation in social commerce contexts.
