Abstract Motivated by a real life problem of sharing social network data that contain sensitive personal information, we propose a novel approach to release and analyse synthetic graphs to protect privacy of individual relationships captured by the social network while maintaining the validity of statistical results. A case-study using a version of the Enron e-mail corpus data set demonstrates the application and usefulness of the proposed techniques in solving the challenging problem of maintaining privacy and supporting open access to network data to ensure reproducibility of existing studies and discovering new scientific insights that can be obtained by analysing such data. We use a simple yet effective randomized response mechanism to generate synthetic networks under ε -edge differential privacy and then use likelihood-based inference for missing data and Markov chain Monte Carlo techniques to fit exponential family random-graph models to the generated synthetic Summary .

Large Strain With Ultra-Low Hysteresis and Enhanced Energy Storage Performance of Mn-Doped 0.65Bi0.5Na0.5TiO3-0.35SrTiO3 Lead-Free Ceramics

: In this paper, the electric-field-induced strain behavior and energy storage performance of MnO-doped 0.65Bi 0.5 Na 0.5 TiO 3 -0.35SrTiO 3 (NBT-ST- x Mn) lead-free ceramics has been investigated. After the introduction of MnO into NBT-ST ceramics, pinched and double P-E hysteresis loops with high P max and negligible P r can be observed due to the introduction of defect dipoles. As a result, a relatively high strain of 0.22% with ultra-low hysteresis of 14% was achieved under a moderate electric field of 60 kV/cm at x =1.0 mol. %. Excellent energy storage performance of 1.14 and 1.17 J cm -3 with a high η of 83 and 80% are achieved at x =0.5 and 1.0 mol. %, respectively. Meanwhile, high electrostriction coeffcient of 0.022 m 4 C 2 with pure electrostrictive characteristics was obtained at x =0.5 mol. %. The results illustrate that the proper selection of base composition and effective chemical modifier can made the NBT-ST an outstanding candidate for actuators and energy storage devices.

Conformal window of gauge theories with four-fermion interactions and ideal walking technicolor

We investigate the effects of four-fermion interactions on the phase diagram of strongly interacting theories for any representation as function of the number of colors and flavors. We show that the conformal window, for any representation, shrinks with respect to the case in which the four-fermion interactions are neglected. The anomalous dimension of the mass increases beyond the unity value at the lower boundary of the new conformal window. We plot the new phase diagram which can be used, together with the information about the anomalous dimension, to propose ideal models of walking technicolor. We discover that when the extended technicolor sector, responsible for giving masses to the standard model fermions, is sufficiently strongly coupled the technicolor theory, in isolation, must have an infrared fixed point for the full model to be phenomenologically viable. Using the new phase diagram we show that the simplest one family and minimal walking technicolor models are the archetypes of models of dynamical electroweak symmetry breaking. Our predictions can be verified via first principle lattice simulations.
IMPROVING VOCABULARY MATERY USING INTRALINGUAL SUBTITLE AND VOCABULARY SELF-COLLECTION STRATEGY

: As one of the language components, vocabulary is an essential factor to master language skills. However, learning vocabulary is assumed to be a boring activity that the students are not interested in. This research aims at improving students’ vocabulary mastery using intralingual subtitle and vocabulary self-collection strategy. A classroom action research was carried out to solve the seventh (7 th ) graders’ problems regarding vocabulary mastery. The subjects of the study were 35 students of seventh grade at one of the junior high schools in Malang. The instruments used in this study were an interview guide for the English teacher, observation notes, questionnaire, and vocabulary tests. The researcher set the criteria of success 75% of the students achieved a score equal or higher than 75 in the vocabulary test and 75% of the students showed positive responses toward the implementation of the strategy. The result of the study showed that (1) 83% of the students or 29 out of 35 students achieved score equal or higher than 75, indicating that the use of intralingual subtitle and vocabulary self-collection strategy improved students’ vocabulary mastery, (2) there were 5 (five) major steps in implementing intralingual subtitle and vocabulary self-collection strategy to improve students’ vocabulary mastery, (3) 90% of the students showed the positive responses to the implementation of the strategy.
ORIGINAL Cellular Plasticity of Defa4 Cre -Expressing Paneth Cells in Response to Notch Activation and Intestinal Injury

required for adenoma formation. ADAM10 deletion had no signi ﬁ cant effect on crypt homeostasis. However, after acute doxorubicin-induced injury, Defa4 Cre -expressing cells contrib-uted to regeneration in an ADAM10 – Notch – dependent manner. CONCLUSIONS: Our studies have shown that Defa4 Cre expressing Paneth cells possess cellular plasticity, can dedifferentiate into multipotent stem cells upon Notch activation, and can contribute to intestinal regeneration in an acute injury model.

Control of complex dynamic nonlinear loading process for electromagnetic mill

Electromagnetic mill installation for dry grinding represents a complex dynamical system that requires specially designed control system. The paper presents model-based predictive control which locates closed loop poles in arbitrary places. The controller performs as gain scheduling prototype where nonlinear model – artiﬁcial recurrent neural network, is parameterized with additional measurements and serves as a basis for local linear approximation. Application of such a concept to control electromagnetic mill load allows for stable performance of the installation and assures fulﬁlment of the product quality as well as the optimization of the energy consumption.
Job search during the COVID-19 crisis q

This paper measures the job-search responses to the COVID-19 pandemic using real-time data on vacancy postings and job ad views on Sweden’s largest online job board. First, new vacancy postings drop by 40%, similar to the US. Second, job seekers respond by searching less intensively, to the extent that effective labour market tightness increases during the ﬁrst three months after the COVID outbreak. Third, they redirect their search towards less severely hit occupations, beyond what changes in vacancies would predict. Overall, these job-search responses have the potential to amplify the labour demand shock. (cid:1) 2020 The Author(s). Published by Elsevier B.V.

Effectiveness of Diabetes Self – Management Education in Thais with Type 2 Diabetes

: Diabetes is a major health problem and economic burden around the world including Thailand. Patient self-management is an important key to help patients control their disease and prevent complications. This study aimed to evaluate a self-management education program in Thais with type 2 diabetes. A retrospective cohort study was performed in 488 people with type 2 diabetes attending the diabetes self-management education program by multidisciplinary team and 488 people who did not attend the program. Mean differences in hemoglobin A 1 c and diabetes medication utilization as dispensed from the hospital’s pharmacy (adjusted to define daily dose) between baseline and follow ups were computed using mixed-effect regression analyses. Cost-benefit was analyzed as a difference between the direct cost of conducting the program and the benefit. Satisfaction, diabetes knowledge and behavioral changes were collected in the intervention group. Results revealed that during the two-year follow up, mean differences in hemoglobin A1c reduction were similar between the two groups. However, the intervention group had a statistically significant reduction in diabetes medication utilization, compared to non-intervention group, especially during the second year. Cost-benefit analysis demonstrated that the diabetes self-management education program provided a cost saving. The intervention group increased their diabetes knowledge, changed diabetes self-care behaviors, and had high satisfaction with the program. Thus, this Diabetes Self-Management Education Program in Type 2 Diabetes is effective and associated with cost savings. Self-management program should be integrated as a routine nursing practice to improve outcomes in people with type 2 diabetes. Pacific Rim Int J Nurs Res 2019; 23(1) 74-86
Analysis of Colombian Trade Agreements from 2007 to 2013

I analyze the firm-level effects on Colombia entering into Preferential Trade Agreements (PTAs) between 2007 and 2013. The combination of detailed firm-level data and PTAs make this article unique. In particular, I look at two separate potential trade-promotion effects of the agreements. The first result deals with how exporting firms in Colombia respond to the tariff cuts in the agreements. The tariff cuts from the agreements increase the size of exports by Colombian firms (the intensive margin); however, tariff cuts do not increase the number of exporting Colombian firms (the extensive margin). The second result deals with how the signed PTAs affect how Colombia sets tariffs on the set of the world. I find that the agreements do not affect Colombia’s other tariffs, a result that further complicates the open question of whether trade agreements lead to lower overall tariffs (building-block effect) or higher overall tariffs (stumbling-block effect).

COPD_A_288792 519..533

1Woolcock Institute of Medical Research, University of Sydney, Glebe, New South Wales, Australia; 2School of Pharmacy, University of Sydney, Camperdown, New South Wales, Australia Purpose: To evaluate the effectiveness of a pilot community pharmacy care model for patients with chronic obstructive pulmonary disease (COPD) to improve: 1) inhaler technique; 2) medication adherence; and 3) uptake of non-pharmacological treatment and prevention activities. Patients and Methods: Forty “host” pharmacies in Sydney were invited to recruit eligible patients and to provide a counselling room/area in their pharmacy for service provision. Eligible patients were referred to two “consultant” pharmacists, specifically trained to deliver a specialized pharmacy COPD service which involved 3 in-pharmacy visits and 2 follow-up phone calls over a 6-month period. The service consisted of 1) inhaler technique assessment; 2) medication adherence assessment; and 3) referrals to the patient’s general practitioner (GP) to facilitate the uptake of non-pharmacological resources as well as to review COPD medications/devices, as required. Pre-post analyses were conducted using paired Student’s t-test and Wilcoxon Signed Rank Test for independent variables and chi-squared tests for proportional data. Results: Nine “host” pharmacies recruited 40 patients, of whom 37 completed the baseline Visit and 27 completed all Visits. A total of 270 interventions were provided by the “consultant” pharmacists with most provided at Visit 1 (176). The most common interventions were addressing patient gaps in COPD knowledge and inhaler technique. A total of 119 referrals were made to GPs for various reasons, the most common being for a COPD action plan, pulmonary rehabilitation, or pneumonia vaccination. There were significant improvements pre-post intervention in inhaler use competence, COPD knowledge, immunization rate for pneumonia, exacerbation rate and COPD plan ownership. Conclusion: In this pilot study, the specialized pharmacy-based COPD care model delivered by “consultant” pharmacists in community pharmacies provided significant health benefits for patients. Further research is needed to assess the model’s effectiveness in a larger population as well as when measured against standard care.
Determination of Safe Mass of Backpack for Students in Tertiary Institutions

Load carrying using backpacks is common among students from primary schools to tertiary institutions in Nigeria. Backpacks are used for carrying books and other school materials. The aim of this study is to determine the mass of backpack that students in tertiary institutions using strain energy principles of the spine. Ten students in a selected tertiary institution participated in the study. A model was developed using strain energy in terms of chest width, chest depth, Young Modulus of Elasticity of articular cartilage, maximum permissible spinal shrinkage, length of spine and body height of the students. The 5 th , 50 th, ands 95 th percentiles of the data obtained were computed using a SPSS 16.0 statistical package. The study confirmed that the model is valid and showed that the maximum backpack load limit for students in tertiary institutions should be 12% of body mass. Similar studies were recommended to be carried out in primary and secondary schools.

We discuss various improvements of the prediction for the light MSSM Higgs boson mass in the hybrid framework of the public code FeynHiggs , which com-bines ﬁxed-order and effective ﬁeld theory results. First, we discusstheresummationoflogarithmiccontributionspropor-tional to the bottom-Yukawa coupling including two-loop (cid:2) b resummation. For largetan β , theseimprovements canleadto large upward shifts of the Higgs mass compared to the existing ﬁxed-order calculations. Second, we improve the imple-mentedEFTcalculationbyfullytakingintoaccounttheeffect of CP -violating phases. As a third improvement, we discuss the inclusion of partial N 3 LL resummation. The presented improvements will be implemented into FeynHiggs .
Variables A ﬀ ecting Peri-Implant Radiographic Bone Loss-8-23 Years Follow-Up

: The aim of this study is to evaluate factors associated with long-term peri-implant bone-loss and to create a statistical model explaining bone-loss. The dental records in a private periodontal practice were screened for implant-patients with a minimal follow-up period of 8 years with periapical radiographs at implant-placement (T0) and last follow-up (T f ). Collected data included demographics, general health, medications, periodontal parameters, implant parameters, bone augmentation procedures, restoration and antagonist data, number of supportive periodontal appointments (SPT), and radiographic bone-loss between T0 and T f . Bivariate and Mixed Logistic Regression analyses were performed. “Goodness-of-ﬁt” of the model was elaborated with Receiver Operating Characteristic Curve (ROC) analyses. Thirty-seven patients receiving 142 implants were included. Mean clinical follow-up period was 11.7 ± 3.7 years (range 8–23). Most implants 64.4% were SPT-maintained more than twice a year. Patients with osteoporosis and smokers were prone to increased radiographic peri-implant bone-loss. External-hex implants placed without guided bone regeneration (GBR) and implants 10–12 mm long and diameter of 3.7–4 mm showed less peri-implant bone-loss. The model’s Area Under the Curve (AUC) was 76.9% (Standard Error 4.6%, CI 67.8–86%).
Journal of HUMAN RESOURCE MANAGEMENT How HRM and knowledge sharing technologies foster virtual team productivity for globally dispersed workforces: A systematic review

Purpose – Virtual Team (VT) productivity is a ﬀ ected by multiple factors, including knowledge sharing, communication and collaboration due to geographical or temporal dispersion. Th is review spans multiple VT contexts globally to determine the practices that contribute to productive VTs. Th e authors ﬁll a research gap by exploring how, across cultures and contexts, VTs overcome temporal and geographical dispersion barriers to share knowledge and foster productivity. Aim – To reveal and understand critical factors that enhance virtual team productivity across multiple sectors and geographical boundaries. Design/methodology/approach – Th e authors conducted a systematic review of twenty-one articles, which resulted from a comprehensive database search and quality screening of the best available evidence. Inductive thematic coding was used to conduct a mixed-method synthesis of ﬁndings across these studies. Findings – Proper implementation of HRM practices combined with the utilization of technology tools that best ﬁt tasks based on temporal and geographical needs can help organizations overcome dispersion issues among virtual teams. Limitations of the study – Due to limitations of available evidence, this systematic review could not address all possible contexts. As a result, applying these ﬁndings across the broadest range of geographic areas and industry sectors should be exercised cautiously. Additionally, a small number of included articles were conceptual papers of relatively lower academic rigor. Practical implications – Th is study highlights the importance of implementing HRM policies related to hiring, induction, training, and on-going appraisal practices to encourage knowledge sharing and build trust and socialization among teams. Originality/value – By synthesizing evidence across various sectors and geographic boundaries, this paper provides rigorously supported recommendations for increasing VT productivity.

Study design: validation study Place and duration of study: Department of Dermatology Military Hospital and Institute of Pathology Rawalpindi from January 2008 to July 2008. Patients and methods: One hundred clinically diagnosed cases of tinea pedis were subjected to direct microscopy with 10% KOH and fungal culture. Results: Direct microscopic examination was positive in 34% and culture in 60% of the cases. The sensitivity and specificity of direct microscopy were 38.33% and 72.5%, respectively keeping culture as gold standard. Direct microscopy had a positive predictive value of 67.65% and negative predictive value of 43.94%. Conclusion: Direct microscopy with 10% KOH may not be sufficient alone therefore cultures should be used for a definitive diagnosis.
Relativistic runaway electrons in tokamak plasmas

An experimental study of the generation of runaway electrons in TEXTOR has been perfonned. From the infrared synchrotron radiation emitted by relativistic electrons, the number of runaway electrons can be obtained as a function of time. In low density discharges cne < lxl019 m-3) runaways are created throughout the discharge and not predominantly in the start-up phase. From the exponential increase in the runaway population and the ongoing runaway production after increasing the density, it is concluded that the secondary generation, i.e. the creation of runaways through close collisions of already existing runaways with thennal electrons, provides an essential contribution to the runaway production. The effective avalanche time of this secondary process is determined to be leff = 0.9 ± 0.2 s.
