dr0wned - Cyber-Physical Attack with Additive Manufacturing

Additive manufacturing (AM), or 3D printing, is an emerging manufacturing technology that is expected to have far-reaching socioeconomic, environmental, and geopolitical implications. As use of this technology increases, it will become more common to produce functional parts, including components for safety-critical systems. AM's dependence on computerization raises the concern that the manufactured part's quality can be compromised by sabotage. This paper demonstrates the validity of this concern, as we present the very first full chain of attack involving AM, beginning with a cyber attack aimed at compromising a benign AM component, continuing with malicious modification of a manufactured object's blueprint, leading to the sabotage of the manufactured functional part, and resulting in the physical destruction of a cyber-physical system that employs this part. The contributions of this paper are as follows. We propose a systematic approach to identify opportunities for an attack involving AM that enables an adversary to achieve his/her goals. Then we propose a methodology to assess the level of difficulty of an attack, thus enabling differentiation between possible attack chains. Finally, to demonstrate the experimental proof for the entire attack chain, we sabotage the 3D printed propeller of a quadcopter UAV, causing the quadcopter to literally fall from the sky.

Early loading of nonsubmerged titanium implants with a chemically modified sand-blasted and acid-etched surface: 6-month results of a prospective case series study in the posterior mandible focusing on peri-implant crestal bone changes and implant stability quotient (ISQ) values.

PURPOSE The aim of this prospective case series study was to evaluate the short-term success rates of titanium screw-type implants with a chemically modified sand-blasted and acid-etched (mod SLA) surface after 3 weeks of healing. MATERIAL AND METHODS A total of 56 implants were inserted in the posterior mandible of 40 partially edentulous patients exhibiting bone densities of class I to III. After a healing period of 3 weeks, all implants were functionally loaded with a screw-retained crown or fixed dental prosthesis. The patients were recalled at weeks 4, 7, 12, and 26 for monitoring and assessment of clinical and radiological parameters, including implant stability quotient (ISQ) measurements. RESULTS None of the implants failed to integrate. However, two implants were considered "spinners" at day 21 and left unloaded for an extended period. Therefore, 96.4% of the inserted implants were loaded according to the protocol tested. All 56 implants including the "spinners" showed favorable clinical and radiographic findings at the 6-month follow-up examination. The ISQ values increased steadily throughout the follow-up period. At the time of implant placement, the range of ISQ values exhibited a mean of 74.33, and by week 26, a mean value of 83.82 was recorded. Based on strict criteria, all 56 implants were considered successfully integrated, resulting in a 6-month survival and success rate of 100.0%. CONCLUSION This prospective study using an early-loading protocol after 3 weeks of healing demonstrated that titanium implants with the modified SLA surface can achieve and maintain successful tissue integration over a period of at least 6 months. The ISQ method seems feasible to monitor implant stability during the initial wound-healing period.
Persisting side‐to‐side differences in bone mineral content, but not in muscle strength and tendon stiffness after anterior cruciate ligament reconstruction

Tendon stiffness may be involved in limiting peak musculoskeletal forces and thus may constitute an upper limit for bone strength. The patellar tendon bone (PTB) graft, which is harvested from the patellar tendon during surgical reconstruction of the anterior cruciate ligament (ACL), is an ideal scenario to test this hypothesis. Eleven participants were recruited who had undergone surgical reconstruction of the ACL with a PTB graft 1–10 years prior to study inclusion. As previously reported, there was no side‐to‐side difference in thigh muscle cross‐sectional area, in maximum voluntary knee extension torque, or in patellar tendon stiffness, suggesting full recovery of musculature and tendon. However, in the present study bone mineral content (BMC), assessed by peripheral quantitative computed tomography, was lower on the operated side than on the control side in four regions studied (P = 0·0019). Differences were less pronounced in the two sites directly affected by the operation (patella and tibia epiphysis) when compared to the more remote sites. Moreover, significant side‐to‐side differences were found in BMC in the trabecular compartment in the femoral and tibial epiphysis (P = 0·004 and P = 0·047, respectively) with reductions on the operated side, but increased in the patella (P = 0·00016). Cortical BMC, by contrast, was lower on the operated side at all sites except the tibia epiphysis (P = 0·09). These findings suggest that impaired recovery of BMC following ACL reconstruction is not because of lack of recovery of knee extensor strength or patellar tendon stiffness. The responsible mechanisms still remain to be determined.
Quantification of poor menstrual hygiene among women of reproductive age group in a slum of Kolkata

Background: Menstruation, a phenomenon unique to the females, is the cyclical shedding of the inner lining of uterus. It is associated with myths and misconceptions and poor knowledge of the normal physiology. Above all, poor menstrual hygiene is a precursor of various morbidities related to the reproductive tract. This study was conducted among women of reproductive age (WRA) group with the aim to assess their socio demographic characteristics, to elicit the knowledge, attitude and practices regarding menstruation and to find the factors associated with the menstrual hygiene practice.Methods: This community based cross-sectional study was conducted among 152 women aged (15-49 years) during December 2017 to January 2018 in Lockgate area of Chetla, Kolkata, West Bengal, India. Data on socio-demographic characteristics, knowledge, attitude and practices towards menstruation were obtained from structured questionnaire. Outcome variable was menstrual hygiene practice. Descriptive statistics and logistic regression were performed to analyze the data by using SPSS 16.0 version.Results: The mean ages of the participants were 27±8 years. Inadequate knowledge, negative attitude and unsatisfactory practice towards menstruation were 73.7%, 65.1% and 62.5% respectively. Significant correlates were Lower level of education [AOR=1.6 (1.3, 2.1)] and less per capita income [AOR=4.7(1.4, 15.5)] for inadequate knowledge. Less per capita income [AOR=4.7(1.9, 11.1)] for negative attitude. Increasing age [AOR=1.1 (1, 1.2)] and lower level of education [AOR=1.3 (1.2, 1.6)] for unsatisfactory menstrual hygiene practice when adjusted with other variables in the multivariate analysis.Conclusions: Women need to be educated about the significance of menstruation, importance of high quality menstrual hygiene management, use of satisfactory absorbent material, proper and hygienic disposal of menstrual absorbent so as to enable them to lead a healthy reproductive life.
Measuring Cohesion and Self-Disclosure in Psychotherapy Groups for Patients with Advanced Cancer: An Analysis of the Psychometric Properties of the Group Therapy Experience Scale

ABSTRACT Objective: Understanding that the group process informs group interventions. However, there is little systematic research on group process variables in psychotherapy groups for patients with cancer. Method: We analyzed the psychometric properties of the Group Therapy Experience Scale (GTES) and evaluated its potential importance in advanced cancer therapy groups. Results: The GTES demonstrated good internal consistency (coefficient alpha = .84). An exploratory factor analysis with varimax rotation yielded four factors. Although all four models were explored, the 1- and 2-factor models appeared to provide the best fit for the data. The GTES total score was negatively correlated with group size and positively correlated with number of groups attended by participants. Further, the GTES total score was correlated with post-intervention spiritual well-being, benefit finding, post-traumatic growth, and quality of life.
Teaching and Learning Supervision, Teachers’ Attitude towards Classroom Supervision and Students’ Participation

This quantitative study aims to identify the supervisory performance in the elements of teaching and learning supervision in secondary schools in the Kubang Pasu district, Kedah. Theory of classroom teaching and learning supervision by Glickman (2004) is the basis of the study. Research instruments are adapted and modified from teaching and learning supervision by Ebmeir (2003), while teacher's attitude towards supervision was taken from the questionnaire by Ramin (2014) and teacher’s teaching competency instruments were taken from the questionnaire by Sayer (1992). The research instrument involved a set of questionnaire consisting of 23 items. The respondents of the study involved 120 teachers in secondary schools in Kedah. The data were analyzed using descriptive statistics and inferential statistics. The results of the analysis showed that there was no significant relationship between the elements of confidence in the classroom teaching and learning supervisor, supervisor support towards teaching with student participation. However there is a significant positive relationship between confidence in the supervisor, supervisor support towards teaching with teacher attitude towards supervision. The findings of this study can be used as a guide for educators to improve classroom teaching and learning supervisory performance in order to improve the teaching profession in the school.
A middle Miocene post‐rift stress regime revealed by dikes and mesoscale faults in the Kakunodate area, NE Japan

Significant advances were made in the last century in the investigations of the Neogene stress history of the NE Japan arc. However, previous studies have failed to fully resolve middle Miocene post‐rift stress conditions owing to their assumption of Andersonian faulting and an inability to determine maximum and intermediate stress axes from dike orientations. We applied the latest methods of paleostress analysis in this study to igneous dikes and mesoscale faults in the Kakunodate area of the NE Japan arc to elucidate post‐rift stress conditions. Stratigraphic constraints and U–Pb dating indicate that the doleritic and dacitic dikes were formed at 16–12 Ma and 15–12 Ma, respectively. Dolerite and dacite dikes yielded NW–SE extensional stresses with intermediate and low stress ratios, respectively. Mesoscale faults in the middle Miocene formations of the studied area indicated similar stresses. We suggest the sluggish deformations resulting in the dike intrusion and faulting in the normal‐faulting stress regime after the termination of intra‐arc rifting at ca. 15 Ma.
Are Chinese Imports Sensitive To Exchange Rate Changes

Estimating the price elasticity of China's imports is difficult because many imports are used to produce exports and because the real effective exchange rate has remained fairly stable. To circumvent the first problem, we control for re-exports, and to increase the discriminatory power of the tests, we employ a panel data set including imports from 25 countries. The results indicate that a 10% RMB appreciation would increase imports for processing and ordinary imports by 3%–4%. As China climbs the value chain, the potential for import substitution and hence the import price elasticity should increase. Thus a renminbi appreciation should help to raise China's imports and rebalance its economy.
Methods Versus Substance: Measuring the Effects of Technology Shocks on Hours

In this paper, we employ both calibration and modern (Bayesian) estimation methods to assess the role of neutral and investment-specific technology shocks in generating fluctuations in hours. Using a neoclassical stochastic growth model, we show how answers are shaped by the identification strategies and not by the statistical approaches. The crucial parameter is the labor supply elasticity. Both a calibration procedure that uses modern assessments of the Frisch elasticity and the estimation procedures result in technology shocks accounting for 2% to 9% of the variation in hours worked in the data. We infer that we should be talking more about identification and less about the choice of particular quantitative approaches.
Professional Development for TESL Teachers: A Course in Transcultural Pragmatics.

Awareness of transcultural pragmatics serves as the foundation for intercultural communicative competence. Explicit teaching of pragmatics in conjunction with intercultural communication training can contribute to the professional development of non-native English-speaking teachers. This article reports on an interdisciplinary attempt to develop a short-term professional development course for TESL teachers. The four-week course in transcultural pragmatics aimed to bring about efficient, learner-driven, experiential, and contextualized professional development through short-term immersion in an intercultural English-speaking environment. The goals of the designed course, introduced to TESL teachers from South Korea, were to (1) introduce pragmatics learning to teacher participants, (2) support participants’ development of intercultural communicative competence during an immersion experience, and (3) facilitate preparation for teaching transcultural pragmatics. The authors conducted classroom research to evaluate the extent to which the course fulfilled the goals set forth. Nearly all of the twenty-five participating teachers self-reported an increase in pragmatics awareness and intercultural communicative competence by the end of the training. They also discovered new approaches for teaching transcultural pragmatics to their elementary students. This report concludes with insights for enhancing the effectiveness of a transcultural pragmatics course that fills a gap in English language teacher education.
Industry Perspective on Journalism Education Curriculum in Malaysia

Purpose -This study investigated media and communication practitioners’ perspectives on the journalism education curriculum in Malaysia. Curriculum plays an important role in providing quality education for students. Journalism is a dynamic field that integrates industrial experience and fundamental knowledge in the field from higher educational institutions. Scholars in the field are divided on the issue of whether it is important for academia to consider input from industrial players in shaping the curriculum on journalism education in higher institutions of learning.Methodology - Drawing from the researchers’ experiences and guidelines from the Malaysian Qualifications Agency, the Taba Model was adapted as the theoretical framework for the study. The study used a semi-structured interview method. Fifteen experts were interviewed. They have served more than 10 years in the media industry and have held various executive positions. The interview protocol was developed based on the literature review and guidelines from the curriculum review of Communication and Media Studies. The interviews were conducted at the offices or homes of interviewees. Each interview ranged from 1 to 2 hours. The data was analysed using thematic analysis.Findings - The findings revealed four main themes, namely 1) Strong general knowledge requirement, 2) the right skills matter, 3) Interest in the field – ability to adapt and learn, and 4) Specialised knowledge. The analysis of interviews indicated that curriculum needs to be revised based on academic convention and industrial needs.Significance - Thus, these findings lend further support to the clarion call for industry and academia to collaborate extensively in nurturing high quality graduates in journalism.
Optimizing MLC-based STT-RAM caches by dynamic block size reconfiguration

The use of STT-RAM as on-chip caches has been widely studied. However, existing works focused mainly on single-level cell (SLC) design while the potential of multi-level cell (MLC) STT-RAM has not yet been fully explored. It is expected that MLC STT-RAM can achieve 2× the storage density of SLC and thus improves system performance. Unfortunately, at the device level, the two-step read/write scheme introduces performance and energy overhead. In this paper, we propose an architectural design to dynamically reconfigure the cache block size for a MLC STT-RAM last-level cache. Our approach place certain hot data chunks in smaller blocks so as to benefit from the lower latency and energy, while keeping the rest in larger blocks to maintain an overall hit rate. Experiment shows that our strategy reduces the performance and energy penalty of MLC STT-RAM caches with a slightly higher miss rate. On average, IPC is increased by 4.6% while energy consumption is reduced by 23.5% compared to the conventional MLC STT-RAM cache.
Demography and Democracy: A Global, District-level Analysis of Electoral Contestation

According to the classical perspective, polity size and democracy are inversely related. In this article, we argue that there is an important exception that manifests itself at the district level in settings where multiparty competition is allowed. Specifically, we find that larger districts encourage greater contestation. This results from a little-noticed mechanical effect as well as from several features of constituencies that are affected by size and have direct repercussions for contestation. To demonstrate this thesis we assembled a unique dataset, the Multi-level Election Archive (MLEA), which unites electoral contests across a variety of districts (national, regional, and local) and elective offices from the eighteenth century to the present, including a total of 88 countries, 2,344 elections, 79,658 districts, and more than 400,000 contests. With this evidence we were able to conduct a broad array of statistical tests, some global and others focused on particular countries or election types, all of which support our general argument.
Universality Classes of Self-Avoiding Crystalline Membranes

We present an analysis of extensive large-scale Monte Carlo simulations of self-avoiding fixed-connectivity membranes for sizes (number of faces) ranging from 512 to 17672 (triangular) plaquettes. Self-avoidance is implemented via impenetrable plaquettes. We simulate the impenetrable plaquette model in both three and four bulk dimensions. In both cases we find the membrane to be flat for all temperatures: the size exponent in three dimensions is nu=0.95(5) (Hausdorff dimension d_H=2.1(1)). The single flat phase appears, furthermore, to be equivalent to the large bending rigidity phase of non-self-avoiding fixed-connectivity membranes - the roughness exponent in three dimensions is xi=0.63(4). This suggests that there is a unique universality class for flat fixed-connectivity membranes without attractive interactions. Finally we address some theoretical and experimental implications of our work.
Female and male youth sport coaches’ perceptions of teaching sportspersonship to female and male athletes

According to the positive youth development framework, sportspersonship and character development is an expected outcome from participation in youth sport. Previous studies have shown mixed results in terms of how gender affects young athletes’ sportspersonship, suggesting it is important to explore how boys and girls are taught about sportspersonship by their coaches. In this study, we interviewed six female and six male youth sport coaches who had coached both girls’ and boys’ teams at recreational and competitive levels to examine coaches’ expectations regarding sportspersonship, with a specific focus on those beliefs associated with gender. Our analysis indicated that gender does matter, as represented in the two emergent higher-order themes—(a) Observations of Athletes’ Sportspersonship Behaviors and (b) Teaching Sportspersonship to Girls and Boys—representative of two and four lower-order themes, respectively. Results showed that gender mattered in terms of coaches’ reported strategies for teaching about sportspersonship, suggesting that youth sport participation builds gendered character.
The Role of Extrinsic Rewards and Cue-Intention Association in Prospective Memory in Young Children

The current study examined, for the first time, the effect of cue-intention association, as well as the effects of promised extrinsic rewards, on prospective memory in young children, aged 5-years-old (n = 39) and 7-years-old (n = 40). Children were asked to name pictures for a toy mole, whilst also having to remember to respond differently to certain target pictures (prospective memory task). The level to which the target picture was associated with the intention was manipulated across two conditions (low- or high-association) for all participants, whilst half of the participants were promised a reward for good prospective memory performance. Results showed a main effect of age, with the 7-year-olds outperforming the 5-year-olds. Furthermore, there was a main effect of reward, with those promised a reward performing better than those who were not. No effect was found for cue-association, with the participants of both age groups performing equally well in both association conditions. No significant interactions were found between any of the variables. The potentially important role of reward in young children’s everyday prospective memory tasks, and possible reasons for the lack of a reflexive-associative effect, are discussed.
