Substantial cognitive skills such reading, writing and learning are dismantled and deformed to suit the nonlinear experience of a digital text that is developed on and transmitted by singular medium — device’s screen. The textuality within digital media urges for new ways of information reproduction, dissemination and consumption. Methods that, simultaneously are dealing with the burden of information overload and the limitations inherited from previous typographic media.

The advent of new typographic standard — OpenType Font Variations appears as a necessary consequence and a natural drive towards a redefinition of digital typography.

The relevance of this study is to speculate about conceptual possibilities that arise, not realistic promises and the implicit theoretical understanding of the processes that are collaterally intertwined.

L’Autore, compiuta una breve sintesi della ‘‘parabola’’ dell’efficacia riflessa del giudicato, ripercorre gli opposti orientamenti della giurisprudenza di legittimità sulla opponibilità del giudicato di condanna nei confronti del danneggiante alla compagnia assicurativa che non ha preso parte al giudizio tra il primo e il danneggiato. Si sofferma, in particolare, sulla soluzione elaborata con la presente decisione, che privilegia l’orientamento (sinora minoritario) secondo cui il giudicato non può essere opposto all’assicuratore rimasto estraneo al giudizio e può, invece, valere come prova documentale nella causa successivamente instaurata tra danneggiato e assicuratore. Ragiona, infine, sulla qualificazione di obbligazione solidale tra assicurato ed assicuratore in ambito R.C. Auto e sulla portata della disposizione dell’art. 1306 c.c., prospettando alcuni possibili sviluppi interpretativi.

RCA is an effective technique for solving production-related problems and used for distinguishing the root causes of significant problems. The present study is conducted to find the root causes of the faulty production line in the automobile industry in Bangladesh that resulted in poor productivity rate and low product quality. Significant QC tools such as Check sheet, Histogram, Pareto diagram, and Cause and Effect diagram are used to collect data and make the analysis to eliminate the defects during the production of Pajero Sport QX automobiles. The outcomes identified that by using Root Cause Analysis (RCA) method, the production line defects can be reduced by about 56.66% on average along with better product quality and productivity.The analysis demonstrated that the procedures can be employed in the automobile assembly plant to mitigate/reduce the faults, in the prioritizing manner. This article presents insight into the possible arisen causes of the faulty production line in an automobile assembly plant and the way to minimize those.

BACKGROUND: Fishbone diagrams have been widely promoted as a systems-focused hazard analysis tool for use in root cause analysis, but they suffer from a number of structural weaknesses, including a unidirectional structure that only takes into account forces that promote an accident (ignoring those that make the accident less likely or less severe) and a means of displaying these forces that does not convey any difference in strength of influence. In a separate but related issue, many healthcare organizations suffer from a lack of change management expertise.

PROPOSED SOLUTION: To address these concerns, I present a novel technique, the Lovebug diagram, which draws from both Fishbone diagrams and force-field analysis (an approach to analyzing planned change). This new technique adds value to both its progenitor methods, while retaining their key strengths and ease of use. It can be used both prospectively, to assess planned changes, and retrospectively to assess unplanned (accidental) departures from the status quo.

DISCUSSION: The Lovebug diagram is a more powerful analytical tool than its progenitor methods; however, overall adoption of systems-focused tools for root cause analysis remains suboptimal. Additional research is needed to determine how best to promote a truly systems-focused approach to healthcare root cause analysis. Beyond this retrospective use of the technique, it represents a simple tool to assist healthcare organizations with prospective change management.

Excerpts:
"The ‘5 whys’ technique is one of the most widely taught approaches to root-cause analysis (RCA) in healthcare. Its use is promoted by the WHO,1 the English National Health Service, [2] the Institute for Healthcare Improvement, [3] the Joint Commission [4] and many other organisations in the field of healthcare quality and safety. Like most such tools, though, its popularity is not the result of any evidence that it is effective. [5–8]"
....
"But the real problem with ‘5 whys’ is not how it is used in RCA, but rather that it so grossly oversimplifies the process of problem exploration that it should not be used at all. It forces users down a single analytical pathway for any given problem,[13] insists on a single root cause as the target for solutions [9 ,13 ,20] and assumes that the most distal link on the causal pathway (the fifth ‘why’) is inherently the most effective and efficient place to intervene."

A complex digital circuit comprises of adder as a basic unit. The performance of the circuit depends on the design of this basic adder unit. The speed of operation of a circuit is one of the important performance criteria of many digital circuits which ultimately depends on the delay of the basic adder unit. Many research works have been devoted in improving the delay of the adder circuit. In this paper we have proposed an improved carry increment adder (CIA) that improves the delay performance of the circuit. The improvement is achieved by incorporating carry look adder (CLA) in the design of CIA contrary to the previous design of CIA that employs ripple carry adder (RCA). A simulation study is carried out for comparative analysis. The coding is done in Verilog hardware description language (HDL) and the simulation is carried out in Xilinx ISE 13.1 environment.

Root cause analysis is perhaps the most widely used tool in healthcare risk management, but does it actually lead to successful risk control? Are there categories of risk control that are more likely to be effective? And do healthcare risk managers have the tools they need to support the risk control process? This systematic review examines how the healthcare sector translates risk analysis to risk control action plans and examines how to do better. It suggests that the hierarchy of risk controls should inform risk control action planning and that new tools should be developed to improve the risk control process.

In this study a comparative life cycle assessment (LCA) was conducted according to a ‘cradle-to-laid’ approach to evaluate the potential environmental impacts related to the use of recycled concrete aggregates (RCAs) as a partial replacement of coarse natural aggregates in the production of Hot Mix Asphalt (HMA). Specifically, three percentages of RCA replacements were analyzed: 15, 30 and 45%. Primary data collected mainly through surveys performed in Colombian contractors from the region of Barranquila were used to model the foreground system. The SimaPro 8.4.0 software was used for modelling the processes analyzed in the case study and all the life cycle inputs and outputs related to the functional unit were characterised during life cycle impact assessment (LCIA) phase into potential impacts according to the TRACI v.2.1 impact assessment methodology. The results of the case study showed that the mixtures incorporating 15 and 30% of RCA can be considered as eco-friendly alternatives to the conventional mixture (i.e. no RCA content), as both allow reductions in all impact categories scores. On the contrary, the mixture that contains 45% of RCA denoted a lower environmental performance than that of the conventional mixture

In this paper, GDI technique implementation of modified Carry Select Adder is presented for the low power applications. The proposed Carry Select Adder can be used RCA using GDI and same size of BEC (binary to excess-1) and Multiplexer. Simulation is performed in T-SPICE using 45nm technology parameters. The results have been compared with 16-bit Regular SQRT-CSA BK using BEC and proposed 16-bit CSA using GDI technique. The performance of the designs is compared in terms of area, power and delay. Comparative analysis shows that the proposed CSA using GDI technique has reduced area and consumes less power.

Risk assessment is widely used to improve patient safety, but healthcare workers are not trained to design robust solutions to the risks they uncover. This leads to an overreliance on the weakest category of risk control recommendations: administrative controls. Increasing the proportion of non-administrative risk control options (NARCOs) generated would enable (though not ensure) the adoption of more robust solutions. Experimentally assess a method for generating stronger risk controls: The Generating Options for Active Risk Control (GO-ARC) Technique. Participants generated risk control options in response to two patient safety scenarios. Scenario 1 (baseline): All participants used current practice (unstructured brainstorming). Scenario 2: Control group used current practice; intervention group used the GO-ARC Technique. To control for individual differences between participants, analysis focused on the change in the proportion of NARCOs for each group. Proportion of NARCOs decre...

Awarded Writing Prize for Final Major Project 'Ethical Portraits'

Abstract:

The representations of individuals within penological structures are intrinsically linked to how ‘criminals’ are portrayed, perceived and have their selfhood removed by these frameworks. Conceptually Ethical Portraits considers the function of autonomy, agency and empowerment for the incarcerated, and questions the ethical duty of representation by the artist implicated in and by their depiction. What does it mean for these subjects who are detained to be represented and assert their identity when marginalised within the prison industrial complex? How do ‘criminals’ and non criminals exhibit this loss of agency via modes of artistic freedom?

Conducted through interviews with Alicia Neal (Chelsea Manning portrait artist) Priscilla Coleman (Courtroom artist), Alyse Emdur (Prison Landscapes Author) and Andrew Tider and Jeff Greenspan (Captured Project) Ethical Portraits considers the representations of individuals through the lens of Visibility, Empathy, Accountability and Freedom. As political advocates, and depictions within the criminal justice system, these artists influence and control the societal perception of ‘criminality’ and the implementation of how portraiture functions within this the context of justice and the carceral system. It is my contention through acts of care, via the written form we can create new knowledge systems to disrupt such systems of representational violence, gesturing towards renewed definitions of selfhood.
