Application of microfabrication in electrochemical sensing.
In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an electrochemical sensor\u27s capabilities. First, a low temperature adhesive bonding procedure for LOC glass devices was evaluated for capillary electrophoresis (CE) applications. This low temperature method utilizes UV adhesive to bond the glass microchips under the assistance of a mask aligner. The bonding process was carried out at room temperature in \u3c 30 minutes, and provided a near 100% success rate. Microchips exhibited similar electroosmotic flow, separation characteristics, stable long-term performance, excellent chip-to-chip reproducibility, as their thermally bonded counter parts. This bonding approach required new but easily implemented structural features. In addition to cost effective and reliable fabrication techniques, microchips designed for long-term unattended electrochemical sensing have been evaluated. Specific advantages of the micro fabrication approach include the capability to create an intelligent design containing features such as redundant sensing electrodes, on-chip reference and auxiliary electrodes, and in situ electrode regeneration/calibration. One system targeted involves continuous pH monitoring in drinking water at solid-state iridium oxide electrodes. Microchips utilized consist of a flow-through silicon platform containing patterned gold electrodes onto which iridium oxide was deposited electrochemically. To simulate drinking water detection scenarios, sensors were integrated into a flow system. Elven equivalent pH electrodes where evaluated for electrode-to-electrode reproducibility, long-term drift, and response to expected interfering agents. With on-chip voltage treatment, absolute potentials measured for an electrode array are within ± 4 mY, with identical (±1 mY/pH unit) calibration slopes. This performance level is sustainable over weeks. Sensors for exhaustive coulometry were designed, fabricated and evaluated. Microchips contained thin-film gold working and Ag/AgCI pseudo-reference electrodes. A custom flow cell containing a counter electrode chamber was constructed to integrate the sensor and to create an electrolysis chamber with a fixed volume. Different chip designs were evaluated for reproducibility and longevity using Fe(CN)63-/4- as model analytes. The relative standard deviation (RSD) for a chip (over 42 days) was 5.5% whereas the sensor-to-sensor reproducibility was within 6.3%. A more practical application for utilizing exhaustive coulometry by the determination of free chlorine in drinking water is briefly evaluated. Initially studies will outline the challenges involved by analyzing hypochlorite

Caught Between a Rock and a Soft Place: Regulating Legal Ethics to Police Corporate Governance in the United States and Hong Kong
Both the United States and Hong Kong have suffered through corporate governance scandals in recent years. The two nations have tried different methods of regulating legal ethics in order to curtail future corporate governance scandals. The United States, via the Sarbanes-Oxley Act of 2002, empowered the Securities and Exchange Commission ( SEC ) to dictate disclosure requirements to U.S. lawyers who represent listed corporations. This mandate creates conflicts between lawyers\u27 duty to keep clients\u27 secrets and their duty to disclose client information for the protection of public interests. Hong Kong took a completely different approach. The Hong Kong Stock Exchange negotiated the Memorandum of Understanding with the Hong Kong Law Society, which clarifies the scope of a solicitor\u27s duties when practicing before the Stock Exchange. This Comment compares the United States and Hong Kong systems of regulating lawyers, specifically considering issues relating to corporate governance. It concludes that the SEC should adopt Hong Kong\u27s style of negotiation and clarification and Hong Kong should adopt the U.S. enforcement stance and definition of the client in order to more effectively prevent corporate scandals before they start
Have Women State Legislators In the United States Become More Conservative?: A Comparison of State Legislators in 2001 and 1988
Women state legislators in the United States in 2001 are more liberal in their political ideology and policy attitudes than their male colleagues, just as they were in 1988. Nevertheless, a notable change is evident in the ideological predispositions of Republican Party women, especially in the lower houses of the legislatures. Republican women representatives in 2001 are more conservative and more like their male counterparts than they were in the late 1980s.En 2001, Les legislatrices d'etat aux Etats-Unis sont plus liberates dans leur ideologic politique et leur attitude envers les politiques que leurs collegues du sexe oppose, tout comme elles l'etaient en 1988. Cependant, un changement notable est evident dans les predispositions ideologiques. Les representantes Republicaines en 2001 sont plus conservatrices et plus comme leurs homologues masculins qu'elles ne l'etaient vers la fin des annees 80
The social role of design representation
Design representation is a crucial part of all design activity. Representations provide a vehicle through which design ideas and decisions are explored, communicated and recorded. Since representation is so fundamental to design, it follows that a deep understanding of the nature and use of representation has the potential to improve current design practice. While there is recognition in the IS literature of the importance of representation, previous IS research has focused almost entirely on the functional aspects of representation, in particular modelling to support various methodologies or particular aspects of design such as database, object-oriented or process modelling. Since the development of an information system is a socio-technical process, this paper argues that we need to understand how representations can facilitate both the specification of the artefact, and the social aspects of design. This paper explores the use of design representation by real-world practitioners. It identifies two hitherto neglected social purposes of representation employed by designers when interacting with clients or users: selective focus, and promotion. The paper concludes by noting that as IS faces increasingly complex design challenges it is timely to examine our understanding of all aspects of design representation including its role in facilitating the social aspects of design.<br /
Effect of a Computer-Based Decision Support Intervention on Autism Spectrum Disorder Screening in Pediatric Primary Care Clinics: A Cluster Randomized Clinical Trial
Importance:
Universal early screening for autism spectrum disorder (ASD) is recommended but not routinely performed.
Objective:
To determine whether computer-automated screening and clinical decision support can improve ASD screening rates in pediatric primary care practices.
Design, Setting, and Participants:
This cluster randomized clinical trial, conducted between November 16, 2010, and November 21, 2012, compared ASD screening rates among a random sample of 274 children aged 18 to 24 months in urban pediatric clinics of an inner-city county hospital system with or without an ASD screening module built into an existing decision support software system. Statistical analyses were conducted from February 6, 2017, to June 1, 2018.
Interventions:
Four clinics were matched in pairs based on patient volume and race/ethnicity, then randomized within pairs. Decision support with the Child Health Improvement Through Computer Automation system (CHICA) was integrated with workflow and with the electronic health record in intervention clinics.
Main Outcomes and Measures:
The main outcome was screening rates among children aged 18 to 24 months. Because the intervention was discontinued among children aged 18 months at the request of the participating clinics, only results for those aged 24 months were collected and analyzed. Rates of positive screening results, clinicians' response rates to screening results in the computer system, and new cases of ASD identified were also measured. Main results were controlled for race/ethnicity and intracluster correlation.
Results:
Two clinics were randomized to receive the intervention, and 2 served as controls. Records from 274 children (101 girls, 162 boys, and 11 missing information on sex; age range, 23-30 months) were reviewed (138 in the intervention clinics and 136 in the control clinics). Of 263 children, 242 (92.0%) were enrolled in Medicaid, 138 (52.5%) were African American, and 96 (36.5%) were Hispanic. Screening rates in the intervention clinics increased from 0% (95% CI, 0%-5.5%) at baseline to 68.4% (13 of 19) (95% CI, 43.4%-87.4%) in 6 months and to 100% (18 of 18) (95% CI, 81.5%-100%) in 24 months. Control clinics had no significant increase in screening rates (baseline, 7 of 64 children [10.9%]; 6-24 months after the intervention, 11 of 72 children [15.3%]; P = .46). Screening results were positive for 265 of 980 children (27.0%) screened by CHICA during the study period. Among the 265 patients with positive screening results, physicians indicated any response in CHICA in 151 (57.0%). Two children in the intervention group received a new diagnosis of ASD within the time frame of the study.
Conclusions and Relevance:
The findings suggest that computer automation, when integrated with clinical workflow and the electronic health record, increases screening of children for ASD, but follow-up by physicians is still flawed. Automation of the subsequent workup is still needed
Five minutes with Susan J. Carroll on women in politics: “There’s no question that some of the barriers are starting to come down, but others still remain”
With the seeming inevitability of Hillary Clinton’s nomination in 2016, the next presidential election may be the first in history to result in a woman president. To coincide with an recent event at the LSE,USAPP editor, Chris Gilson and Democratic Audit’s Sean Kippin, spoke to Professor Susan Carroll, author of ‘More Women Can Run: Gender and Pathways to the State Legislatures’ on the likelihood of a Clinton presidency and on the challenges faced by aspirant female politicians and established woman leaders
Feasibility of Mindfulness at Work: A Continuing Education Program for Occupational Therapy Practitioners Experiencing Burnout
Healthcare professionals, including occupational therapy practitioners, are experiencing epidemic levels of burnout. Professional organizations have prioritized research and programming to address burnout. This study evaluated the feasibility of an evidence-based virtual mindfulness continuing education program, Mindfulness at Work, and the mindfulness strategies participants learned and embedded into their workday. This program was developed and facilitated by an occupational therapist who is also a registered advanced yoga teacher. A total of 11 occupational therapy practitioners experiencing burnout met with the facilitator for once-weekly synchronous sessions over three weeks. OT practitioners were taught mindfulness strategies to use throughout their workday. Participants practiced the strategies at work between sessions and discussed their experiences during subsequent sessions. Aspects of the feasibility of both the program and the mindfulness strategies were measured post-only. Participant burnout was measured pre and post. Participants rated the virtual mindfulness continuing education program and mindfulness strategies as acceptable, appropriate, and feasible. There were significant decreases in pre- and post-test burnout scores during this preliminary evaluation. Attendance and retention rates were high. Eligibility criteria challenged recruitment capability
