Polymer filament–based in situ microrobot fabrication using magnetic guidance
Authors: Li Zhe , Diller Eric
Published: February 2017

In this article, we present a new three-dimensional printing inspired method for in situ fabrication of mobile magnetic microrobots with complex topology by bending a polymer filament on demand directly inside an enclosed operational environment. Compared with current microrobot fabrication methods that typically involve multiple microfabrication steps and complex equipment, the proposed method is simply and fast. The target shape is formed as the filament is fed through a hot needle inserted into the workspace, and the filament bending moment is induced by attaching a tip magnet at the end of the filament and projecting magnetic fields wirelessly from external electromagnetic coils. The filament bending mechanics and the behavior of the bending zone are analyzed and verified through bending experiment. A shape planner is developed for automatically controlling the fabrication process of any desired planar shapes, and the shape creation potential of this method is also studied. Magnetically active millimeter-scale robotic devices of different planar shapes are fabricated using polylactic acid filament with diameter as small as 100 μm. As demonstrations of the in situ formation of functional microrobotic devices, a micro-gripper is fabricated and controlled to assemble a cell cage. A micro-spring is created as a manipulating tool with force sensing capability. We, thus, show the utility of the fabrication method for creating complex microrobot shapes remotely in enclosed environments for advanced microrobotic applications, with the potential for scaled down applications in health care and microfluidics.

Published: February 2017

Many works in the literature have studied the kinematical and dynamical issues of parallel robots. But it is still difficult to extend the vast control strategies to parallel mechanisms due to the complexity of the model-based control. This complexity is mainly caused by the presence of multiple closed kinematic chains, making the system naturally described by a set of differential–algebraic equations. The aim of this work is to control a two-degree-of-freedom parallel manipulator. A mechanical model based on differential–algebraic equations is given. The goal is to use the structural characteristics of the mechanical system to reduce the complexity of the nonlinear model. Therefore, a trajectory tracking control is achieved using the Takagi-Sugeno fuzzy model derived from the differential–algebraic equation forms and its linear matrix inequality constraints formulation. Simulation results show that the proposed approach based on differential–algebraic equations and Takagi-Sugeno fuzzy modeling leads to a better robustness against the structural uncertainties.
Optimal grasp planning for a dexterous robotic hand using the volume of a generalized force ellipsoid during accepted flattening
Authors: Jia Peng , Li Wei li , Wang Gang , Li Song Yu
Published: February 2017

A grasp planning method based on the volume and flattening of a generalized force ellipsoid is proposed to improve the grasping ability of a dexterous robotic hand. First, according to the general solution of joint torques for a dexterous robotic hand, a grasping indicator for the dexterous hand—the maximum volume of a generalized external force ellipsoid and the minimum volume of a generalized contact internal force ellipsoid during accepted flattening—is proposed. Second, an optimal grasp planning method based on a task is established using the grasping indicator as an objective function. Finally, a simulation analysis and grasping experiment are performed. Results show that when the grasping experiment is conducted with the grasping configuration and positions of contact points optimized using the proposed grasping indicator, the root-mean-square values of the joint torques and contact internal forces of the dexterous hand are at a minimum. The effectiveness of the proposed grasping planning method is thus demonstrated.
To change or not to change – That is the question: A qualitative study of lifestyle changes following acute myocardial infarction

Published: February 2017

Objective

The purpose of this study was to investigate key factors related to lifestyle changes following acute myocardial infarction (AMI) by eliciting survivors’ subjective needs for, attitudes towards and experiences with behaviour changes in their everyday life to improve future interventions promoting lifestyle changes.

Methods

Semi-structured interviews were conducted with 21 individuals who had recently experienced an AMI. The interviews were audio-recorded and transcribed verbatim. The data were analysed using qualitative content analysis.

Results

The data analysis revealed that lifestyle changes following AMI are influenced by a combination of individual (physical and psychological) and social factors that can be grouped into facilitators and barriers. The interviews indicated the need for more personalised information regarding the causes and risk factors of illness, the benefits of lifestyle changes and the importance of including significant others in lifestyle advice and education and of individualising support.

Discussion

Lifestyle change is a continuous process that is not completed within a few months after a cardiac event. Considering the identified themes when developing interventions to promote lifestyle changes following AMI may enhance the effectiveness and sustainability of such interventions.
One Forest Is Not Like Another

Agricultural expansions and unsustainable resource extraction increasingly threaten biodiversity worldwide. Thus, knowledge on landscape management opportunities that contribute to biodiversity conservation and provide the necessary natural resources is urgently needed. Community-based natural resource management can be one solution to achieve sustainable resource provisioning and biodiversity conservation. However, evidence on the effectiveness of the management transfers to local communities for biodiversity conservation is scarce. We use a case study from south-western Madagascar to discuss the integration of community-managed forests, including forests protected by local taboos, into measures for biodiversity conservation. In particular, we compared reptile community composition and species diversity between differently managed forest sectors (used and less-used) in two community forests. We hypothesized that forest use affects biodiversity depending on the people’s acceptance of management regulations. Our results show that reptile community composition was affected by forest management if the less used forest part was protected by traditional taboos. If the people did not respect regulations for resource extraction, habitat protection failed which led to a homogenization of reptile community composition across different forest parts. This highlights that the type of forest management and use and its acceptance in the rural communities determines the contribution of community forests to biodiversity conservation.

Step Up & Be Counted! (Step Up!) is a joint initiative of the National Association of School Nurses (NASN) and the National Association of State School Nurse Consultants (NASSNC). The aim of Step Up! is for all school nurses across the nation to collect and submit specific, uniform data points for all their students. The program was initiated in 2014. In the second year of data collection, 2015-16, school nurses from more states contributed data, and many states reported on a larger number of school nurses reporting data. This article reports the progress we have made in data collection and reporting in year two.
Temporal Dimensions of Social Change in Sustainable Communities
Authors: Botta Marta
Published: February 2017

This article offers a macrohistory perspective on sociocultural change to reveal a wide spectrum of diverse approaches to time across cultures and history. The Causal Layered Analysis explores three distinct concepts of time: the cyclic, linear, and eternal views of time. The cyclic concept of time was dominant in tribal groups of primitive communism in the Palaeolithic period, and linear time is intrinsic to the goal-oriented late capitalist era. As a reaction to the accelerating pace of life in the twentieth century, a slow living movement develops in various models of sustainable communities. Thus, a changed worldview and a different approach to time can be observed in emerging alternative cultures. The case study of Damanhur, a sustainable community promoting time travel as a tool of cultural transformation, provides an example of a transmodern culture embracing eternal time. The path of evolution of the concept of time across history was established through literature, as well as by empirical evidence of select examples. Thus, the hypothesis that social change can be traced by observing culture-dependent approaches to time through history has been confirmed. The analysis of the changing concept of time across historic dimensions revealed sociocultural implications of the current linear concept, as well as indicated emerging changes of consciousness reflected in novel ways of regarding time and space, as a function of alternative futures.
Time and the Ontology of the Future
Authors: Staley David J.
Published: February 2017

Ontology is the philosophical inquiry into what exists, and whether or not the phenomenon under consideration exists. The ontology of the future, then, means an examination of the nature and existence of the future. To inquire into the ontology of the future is not to ask “what is the future?” or “what will happen in the future?” but to, instead, consider the nature of the container that is the future. Is the future a kind of container of events? Is it a space that contains all future happenings? If so, this implies that the future already exists, like a distant land toward which we might travel. Perhaps the future is a container that holds only potential occurrences, and is thus not fully in existence. The future might not exist at all, as there are no preexisting occurrences and, thus, nothing to contain such occurrences. The future is a void, and only comes into existence when we experience it, but there is nothing that preexists. The future might already exist because it is a repetition of events that have previously occurred. The goal of the present article is to situate the problem of the ontology of the future within a wider historical context. It has been a commonplace since the Scientific Revolution to view time as linear and the future as an ontologically existent realm linked to past and present. Our understanding of the ontology of the future has a history, meaning that there have been differing ideas about the nature and existence of the future. Generally speaking, how a society understands the shape of time frequently determines how that society views the reality of the future. There is every reason to expect that our view of the nature and actuality of the future will change alongside changes in our understanding of time.

Exertional dyspnoea in interstitial lung diseases: the clinical utility of cardiopulmonary exercise testing
Authors: Bonini Matteo , Fiorenzano Giuseppe
Published: February 2017

Interstitial lung diseases (ILDs) represent a heterogeneous group of pathologies characterised by alveolar and interstitial damage, pulmonary inflammation (usually associated with fibrosis), decreased lung function and impaired gas exchange, which can be attributed to either a known or an unknown aetiology. Dyspnoea is one of the most common and disabling symptoms in patients with ILD, significantly impacting quality of life. The mechanisms causing dyspnoea are complex and not yet fully understood. However, it is recognised that dyspnoea occurs when there is an imbalance between the central respiratory efferent drive and the response of the respiratory musculature. The respiratory derangement observed in ILD patients at rest is even more evident during exercise. Pathophysiological mechanisms responsible for exertional dyspnoea and reduced exercise tolerance include altered respiratory mechanics, impaired gas exchange, cardiovascular abnormalities and peripheral muscle dysfunction.

This review describes the respiratory physiology of ILD, both at rest and during exercise, and aims to provide comprehensive and updated evidence on the clinical utility of the cardiopulmonary exercise test in the assessment and management of these pathological entities. In addition, the role of exercise training and pulmonary rehabilitation programmes in the ILD population is addressed.

Background

HPV infection causes cervical cancer, mediated in part by the degradation of Scribble via the HPV E6 oncoprotein. Recently, Scribble has been shown to be an important regulator of the Hippo signaling cascade. Deregulation of the Hippo pathway induces an abnormal cellular transformation, epithelial to mesenchymal transition, which promotes oncogenic progression. Given the recent rise in oropharyngeal HPV squamous cell carcinoma we sought to determine if Hippo signaling components are implicated in oropharyngeal squamous cell carcinoma.

Methods

Molecular and cellular techniques including immunoprecipiations, Western blotting and immunocytochemistry were used to identify the key Hippo pathway effector Yes-Associated Protein (YAP) 1. Oropharyngeal tissue was collected from CO2 laser resections, and probed with YAP1 antibody in tumor and pre-malignant regions of HPV positive OPSCC tissue.

Results

This study reveals that the Scribble binding protein Nitric Oxide Synthase 1 Adaptor Protein (NOS1AP) forms a complex with YAP. Further, the NOS1APa and NOS1APc isoforms show differential association with activated and non-activated YAP, and impact cellular proliferation. Consistent with deregulated Hippo signaling in OPSCC HPV tumors, we see a delocalization of Scribble and increased nuclear accumulation of YAP1 in an HPV-positive OPSCC.

Conclusion

Our preliminary data indicates that NOS1AP isoforms differentially associate with YAP1, which, together with our previous findings, predicts that loss of YAP1 enhances cellular transformation. Moreover, YAP1 is highly accumulated in the nucleus of HPV-positive OPSCC, implying that Hippo signaling and possibly NOS1AP expression are de-regulated in OPSCC. Further studies will help determine if NOS1AP isoforms, Scribble and Hippo components will be useful biomarkers in OPSCC tumor biology.

Published: February 2017

Circular RNAs (circRNAs) are highly stable, covalently closed RNAs that are regulated in a spatiotemporal manner and whose functions are largely unknown. These molecules have the potential to be incorporated into engineered systems with broad technological implications. Here we describe a switch for inducing back-splicing of an engineered circRNA that relies on the CRISPR endoribonuclease, Csy4, as an activator of circularization. The endoribonuclease activity and 3′ end-stabilizing properties of Csy4 are particularly suited for this task. Coexpression of Csy4 and the circRNA switch allows for the removal of downstream competitive splice sites and stabilization of the 5′ cleavage product. This subsequently results in back-splicing of the 5′ cleavage product into a circRNA that can translate a reporter protein from an internal ribosomal entry site (IRES). Our platform outlines a straightforward approach toward regulating splicing and could find potential applications in synthetic biology as well as in studying the properties of different circRNAs.
Splenic Vein Thrombosis as a Rare Complication of Disseminated Tuberculosis – Imaging Diagnosis and Case Report
Authors: Roy Satarupa , Bhatt Shuchi , Rawal Rajesh , Tandon Anupama , Meena Neha
Published: February 2017

Background: Venous thromboembolism is a known but rare complication associated with Mycobacterium tuberculosis infection. The reported incidence of venous thromboembolism is 1.5–3.4% of infected patients, and it occurs due to a hypercoagulable state induced by the associated inflammation.

Case Report: A young woman with pulmonary tuberculosis was found to have disseminated tuberculosis and a clinically unsuspected partial thrombus in the splenic vein on imaging. Ultrasound demonstrated hepato-splenomegaly with multiple granulomas as well as ascites and a left-sided pleural effusion.

An increased calibre of the splenic vein with a hyperechogenicity within it raised the suspicion of a thrombus, which was confirmed on a contrast-enhanced CT examination. CECT of the abdomen also showed a small peripheral splenic infarct, while CECT of the chest revealed bilateral military lesions in the lungs along with necrotic mediastinal lymphadenopathy. The final imaging diagnosis was disseminated tuberculosis complicated by splenic vein thrombosis. A timely institution of anti-coagulant and anti-tubercular treatment led to a complete resolution of the splenic vein thrombosis.

Conclusions: Contrast-enhanced CT serves as a useful imaging tool for the detection of venous thrombosis and for the estimation of a complete burden of the disease. This condition should be kept in mind by both clinicians and radiologists and looked for in order to prevent life-threatening complications.

Cross-Sided Liquidity Externalities
Authors: Tham Wing Wah , Sojli Elvira , Skjeltorp Johannes A.
Published: February 2017

We study the empirical relevance of the participation externality between liquidity suppliers (makers) and demanders (takers), i.e., whether liquidity demand attracts or reduces liquidity supply, and vice versa. We use exogenous shocks to exchange fees and technology as experiments to identify cross-sided complementarities between liquidity suppliers and demanders in the U.S. equity market. We find that the externality is large and positive, on average. However, the externality is negative in periods of high adverse selection. We quantify the economic significance of the externality by evaluating an exchange’s revenue after a fee change.

Information Sharing in Competing Supply Chains with Production Cost Reduction
Authors: Ha Albert Y. , Tian Quan , Tong Shilu
Published: February 2017

We consider the problem of sharing demand information in two competing supply chains, each consisting of one manufacturer and one retailer. Information sharing allows a manufacturer’s wholesale price to respond to demand signal, which benefits the supply chain if the manufacturer is efficient in cost reduction and hurts it otherwise. It also allows a manufacturer’s cost reduction level to respond to demand signal, which always benefits the supply chain. A supply chain that engages in information sharing triggers a reaction from the rival chain. Such a reaction may benefit or hurt the first supply chain, depending on whether the retailers compete on quantity or price, and whether or not the manufacturers are efficient in cost reduction. With quantity competition, information sharing occurs when the manufacturers are efficient in cost reduction. It is more likely to occur when either information is less accurate or competition is less intense. With price competition, information sharing occurs when either competition is intense or the manufacturers are efficient in cost reduction. It is more likely to occur when information is more accurate. When information sharing is beneficial to a supply chain, a manufacturer can buy information from a retailer with a side payment, which is zero if the manufacturer is sufficiently efficient in cost reduction.

Published: February 2017

This study aimed to find out, empirically, the effect of myopic loss aversion and accounting information on the behavior of investors. The method used is pure experiment by using a 2×2 factorial design between subjects. The results show that myopic loss aversion and accounting information positively affects investor behavior. Another result reveals that there is a difference in treatment (frequent and infrequent) that was equally given accounting information. There is a difference of treatment (frequent and infrequent) that was not given accounting information, but the results return obtained by investors with the treatment of frequent is higher than investors with the treatment of infrequent, it indicates that investors that were treated frequently to be more willing to take a risk, and investors proved not to experience MLA. It was not found the difference in treatment (frequent and infrequent) with accounting information with those that were not given accounting information. It can be caused by a lack of understanding of investors (in this case by the students) in interpreting and analyzing accounting information as well as private signals that still dominate the investors.

Ideological Heterogeneity and the Rise of Donald Trump
Authors: Carmines Edward G. , Ensley Michael J. , Wagner Michael W.
Published: February 2017

In the days after the 2016 election, a variety of explanations has been offered to explain Donald Trump’s unique ascendancy in American politics. Scholars have discussed Trump’s appeal to rural voters, his hybrid media campaign strategy, shifts in voter turnout, Hillary Clinton’s campaign advertising strategy, economic anxiety, differences in sexist and racist attitudes among Trump voters and so forth. Here, we add another key factor to the conversation: Trump’s appeal to a smaller, often ignored, segment of the electorate: populist voters. Building upon our previous work – demonstrating that while American political elites compete across a single dimension of conflict, the American people organize their attitudes around two distinct dimensions, one economic and one social – we use 2008 American National Elections Study (ANES) data and 2016 ANES primary election data to show that populist support for Trump, and nationalist policies themselves, help us to understand how Trump captured the Republican nomination and the White House.

On the morning after, the aggregate story of the American elections of 2016 was one of surprise. Professional pundits – not to mention the pollsters, those masters of disaggregation – had been rather strikingly wrong. So, one of the major products of the elections of 2016 was a major research project for these professional disaggregators. But can those who treat elections as aggregate phenomena – as patterned wins and losses across time – fit these results into an ongoing pattern? Within this pattern, what looks familiar and what looks anomalous? Or, said the other way around, when

Rectangular slots are etched on signal transmission line (TL) to suppress the spurious band without altering the performance and size of filter. The filter is designed for low pass frequency band with cut-off frequency of 3.5 GHz. The proposed metamaterial structure has several prominent advantages in term of selectivity up to 34 dB/GHz and compactness with average insertion loss less than 0.4 dB. It has multiple applications in wireless communication (such as GSM900, global navigation satellite system (1.559–1.610 GHz), GSM1800, WLAN/WiFi (2.4–2.49 GHz) and WiMAX (2.5–2.69 GHz)). The design parameters have been measured and compared with the simulated results and found excellent agreement. The electrical size of proposed filter is 0.14λ
Studies on the Parametric Effects of Plasma Arc Welding of 2205 Duplex Stainless Steel
Authors: Selva Bharathi R. , Siva Shanmugam N. , Murali Kannan R. , Arungalai Vendan S.
Published: February 2017

This research study attempts to create an optimized parametric window by employing Taguchi algorithm for Plasma Arc Welding (PAW) of 2 mm thick 2205 duplex stainless steel. The parameters considered for experimentation and optimization are the welding current, welding speed and pilot arc length respectively. The experimentation involves the parameters variation and subsequently recording the depth of penetration and bead width. Welding current of 60–70 A, welding speed of 250–300 mm/min and pilot arc length of 1–2 mm are the range between which the parameters are varied. Design of experiments is used for the experimental trials. Back propagation neural network, Genetic algorithm and Taguchi techniques are used for predicting the bead width, depth of penetration and validated with experimentally achieved results which were in good agreement. Additionally, micro-structural characterizations are carried out to examine the weld quality. The extrapolation of these optimized parametric values yield enhanced weld strength with cost and time reduction.

Acinetobacter baumannii, a non-fermenting Gram-negative bacterium, is a common pathogen in intensive care units (ICU) that is easily spread through contact and can cause nosocomial outbreaks. This study investigated the risk factors associated with outbreaks of pan-drug resistant Acinetobacter baumannii (PDR-Ab) infection by studying a suspected nosocomial outbreak in a comprehensive ICU in a teaching hospital in China, and discusses the effectiveness of current prevention and control measures.

Pathogen detection methods involving pulsed field gel electrophoresis (PFGE) were employed to survey patients infected or colonized with PDR-Ab. An epidemiological investigation was conducted to determine the risk factors for infection or colonization with PDR-Ab between 1 October 2014 and 16 January 2015.

The rate of PDR-Ab infection in the ICU was higher during the period from 1 October 2014 to 16 January 2015 than it was between 1 October 2013 and 16 January 2014. Only two cases were confirmed to have the same genotype. Risk factors were explored and the rate of infection was found to be controlled by interventions targeting these risk factors.

A decrease in the number of infections was observed after multiple prevention and control measures were implemented, preventing the outbreak of a nosocomial infection.
Numerical Analysis of Exhaust Emission from an Aero Gas Turbine Combustor under Fuel-Rich Condition
Authors: Mishra R. K. , Chandel Sunil
Published: February 2017

Emission characteristic of an aero gas turbine combustor has been studied under fuel-rich condition. The combustor has been designed to operate at rich fuel-air mixture and may experience very high mixture up to equivalence ratio of 3.0 in the primary zone in the event of atomizer deterioration and flow passage distortion or during some maneuver. The concentration of major engine emission/pollutant constituents at combustor exhaust such as CO, NOx, soot, unburned hydrocarbons and atmospheric pollutants such as CO2 and water vapor has been analyzed at fuel-rich high equivalence ratio using computational model in CFX. The pollutant concentrations are found to be increased with increase in equivalence ratio. Atomization quality in terms of fuel droplet size is found to have a significant contribution in the concentration of various species at combustor exit.

New antidepressant pharmacotherapies that provide rapid relief of depressive symptoms are needed. The NMDA receptor antagonist ketamine exerts rapid antidepressant actions in depressed patients but also side effects that complicate its clinical utility. Ketamine promotes excitatory synaptic strength, likely by producing high-frequency correlated activity in mood-relevant regions of the forebrain. Negative allosteric modulators of GABA-A receptors containing α5 subunits (α5 GABA-NAMs) should also promote high-frequency correlated electroencephalogram(EEG) activity and should therefore exert rapid antidepressant responses. Because α5 subunits display a restricted expression in the forebrain, we predicted that α5 GABA-NAMs would produce activation of principle neurons but exert fewer side effects than ketamine. We tested this hypothesis in male mice and observed that the α5 GABA-NAM MRK-016 exerted an antidepressant-like response in the forced swim test at 1 and 24 h after administration and an anti-anhedonic response after chronic stress in the female urine sniffing test (FUST). Like ketamine, MRK-016 produced a transient increase in EEG γ power, and both the increase in γ power and its antidepressant effects in the forced swim test were blocked by prior administration of the AMPA-type glutamate receptor antagonist 2,3-dioxo-6-nitro-1,2,3,4-tetrahydrobenzo[f]quinoxaline-7-sulfonamide (NBQX). Unlike ketamine, however, MRK-016 produced no impairment of rota-rod performance, no reduction of prepulse inhibition (PPI), no conditioned-place preference (CPP), and no change in locomotion. α5 GABA-NAMs, thus reproduce the rapid antidepressant-like actions of ketamine, perhaps via an AMPA receptor (AMPAR)-dependent increase in coherent neuronal activity, but display fewer potential negative side effects. These compounds thus demonstrate promise as clinically useful fast-acting antidepressants.

Research indicates that student learning of science, student attitudes toward science, and their motivation to learn science and pursue science-related careers is related to classroom instruction. This study examined anatomy and physiology (A&P) classes in a south Texas high school where 97 percent of students are Hispanic bilingual learners. Classes were assigned to control or treatment groups, with the treatment group receiving instruction designed to help students develop a deeper understanding of anatomy vocabulary related to brain structures by making connections to these words in everyday life as well as to their understanding of Spanish. Main effects between group and test scores were significant, with the control group reporting higher test scores than the treatment group. We attribute this finding to a bleed-over of the treatment group instructional design to the control group. In addition, significant differences in mean and median scores were observed with respect to intrinsic motivation and self-efficacy. The statistically significant increases in learning for both groups suggests the activity-, problem-, and project-based (APB) curriculum has the potential to be an effective type of instruction, especially for bilingual learners.

Transpiration is one of the most important water-related phenomena in plant physiology. Various types of semi-quantitative methods for demonstrating this process are available, one of which is the potometer. We offer here a better design for the single-leaf potometer resulting in an easy-to-make, unbreakable, and basic instrument that can reduce the cost of laboratory work in biology instruction and provide a tool that students might use for science fair projects.
Botanical Phylo-Cards: A Tree-Thinking Game to Teach Plant Evolution
Authors: Gibson J. Phil , Cooper Joshua T.
Published: February 2017

Students often have limited understanding of the major innovations in plant evolution. We developed a card sorting activity based on tree thinking that is suitable for students with a wide range of abilities and experience. Through this activity, students learn how scientists organize taxa into biologically meaningful, natural groups that illustrate important events in terrestrial plant evolution. The activity corresponds to several NGSS standards and is suitable for use in classroom or laboratory settings and as a public educational outreach activity.

The Botanical Phylo-Card Game addresses several components of Next Generation Science Standards (NGSS Lead States, 2013) such as Inheritance/Variation in Traits (3-LS3-1, HS-LS3-1, HS-LS4-2) and Natural Selection/Evolution (MS-LS4-2, HS-LS4-1). The game involves disciplinary core ideas about biodiversity, evolution, and common ancestry; crosscutting concepts regarding identification and interpretation of patterns; and scientific practices of constructing explanations and engaging in arguments from evidence that can guide individualized implementation and assessment of the activity by different instructors.
