The main challenge we face in making quantum computing a reality is error control. For this reason it is necessary to study whether the hypotheses on which the threshold theorem has been proved capture all the characteristics of quantum errors. The extraordinary difficulties that we find to control quantum errors effectively together with the little progress in this endeavor, compared to the enormous effort deployed by the scientific community and by companies and governments, should make us reflect on the road map to quantum computing. In this work we analyze error control in quantum computing and suggest that discrete quantum computing models should be explored. In this sense, we present a concrete model but, above all, we propose that Quantum Physics should be taken one step further, in order to allow discretization of the quantum computing model.

This chapter is engaged with photography’s fundamental challenge: it is both documentary evidence, in which the camera is a tool of a technician, and a work of art, in which the click of the shutter is but one step on the road to creating an art photograph. It opens with Baltermants’s soaring career with Izvestiia until June 1942, when he was fired for mislabeling a photograph of a blown-up tank and was sent to a penal battalion that fought at Stalingrad. The experience nearly cost him his life. After the victory by the Allies, photographs were used as evidence in war crimes trials, including Baltermants’s. At the end of the war, he returned to photographic preeminence. After Stalin’s death, he became a leading documenter of global Soviet power under Nikita Khrushchev. He took pictures in Vietnam, India, and China, and his work appeared in domestic and international art exhibitions.

Regional Water Company (PDAM) is a company that is managed by the Local Government to operate as a body of community service that is selling services and trust in society. PDAM has to must still understand the behavior and wishes of the customers in the utilization of services of drinking water and the discretion of the company in the form term of service standards set, so as to provide a good service that causes customers to be satisfied.                One of the PDAM in Indonesia is PDAM Tirta Kahuripan located in Bogor. PDAM Tirta Kahuripan is often get complaints from their customers. Of the Many customers who complained about the poor service system so far is are leaky pipe impact on the high notes of erroneous meter, water quality is still dirty muddy, and sluggish handling of a complaint.                The aim of research is to find out a complaint management system in order to improve customer satisfaction at PDAM Tirta Kahuripan.               The theory used to analyze a system of customer complaints is the referring to the Minister of Administrative Reform and Bureaucratic Reform No. 3 Year of 2015 on the Road Map Development Complaints Public Service Nationwide with 3 sizes of complaint management : outcomes, targets, and programs. While, improving customer satisfaction using Fandi Tjiptono and Gregory Cahndra theory (2006: 130) with four dimensions to measure customer satisfaction : the system of complaints and suggestions, Customer satisfaction Survey, Ghost Shopping (Shadow Customer), and Customer Switching Analysis.               Research methods used in this research is descriptive quantitative method using questionnaires / questionnaire and interviews as the main instrument to collect data.                The results showed that the management of customer complaints in accordance with  to existing procedures with the acquisition of a score of is 3.32 according to the with category of interpretation of the category is as quite good enough (moderate).  Meanwhile, the results of data analysis by increasing customer satisfaction PDAM Tirta Kahuripan obtained a score of is 2.83 in the category with category of interpretation as good enough (moderate).                  Nevertheless, But there is a needs to be have a system or application that can be accessed in to the customer complaints and the organizers therefore PDAM can respond and follow complaint subsequently. Keywords : Complaint Management System , Customer Satisfaction

AbstractWe analyse the importance of legitimacy on public policy support by comparing how drivers of public policy attitudes evolve across the policy process consisting of the input (the processes forgoing acquisition of power and the procedures permeating political decisionmaking), throughput (the inclusion of and interactions between actors in a governance system) and output (the substantive consequences of those decisions) stages. Using unique panel data through three phases of the implementation of a congestion tax in the Swedish city of Gothenburg, we find that legitimacy is indeed important in explaining policy support. Moreover, we find a lingering effect where support in one phase depends on legitimacy both in the present and in previous phases. Hence, our study takes us one step further on the road to understand the complicated dynamic mechanisms behind the interactions between policymaking, policy support, and the legitimacy and approval of politicians and political processes.

This study investigated the effectiveness of the WAIS–R Block Design subtest to predict everyday spatial ability for 65 university undergraduates (15 men, 50 women) who were administered Block Design, the Standardized Road Map Test of Direction Sense, and the Everyday Spatial Activities Test. In addition, the verbally loaded National Adult Reading Test was administered to assess whether the more visuospatial Block Design subtest was a better predictor of spatial ability. Moderate support was found. When age and sex were accounted for, Block Design accounted for 36% of the variance in performance ( r = -.62) on the Road Map Test and 19% of the variance on the performance of the Everyday Spatial Activities Test ( r = .42). In contrast, the scores on the National Adult Reading Test did not predict performance on the Road Map Test or Everyday Spatial Abilities Test. This suggests that, with appropriate caution, Block Design could be used as a measure of everyday spatial abilities.

<p>Throughout the vast majority of its history, hedonism about well-being has been perennially unpopular (Feldman 2004). The arguments in this essay take steps towards reviving the plausibility of hedonism about well-being. The main argument currently used to refute hedonism about well-being, the Argument from False Pleasures, is shown to lack sufficient evidence to be compelling. The main evidence provided for the Argument from False Pleasures comes in the form of two thought experiments, the Experience Machine (Nozick 1974) and the Deceived Businessman (Kagan 1998). These thought experiments typically produce strong intuitive responses, which are used to directly support the Argument from False Pleasures. This essay investigates how theories of well-being are currently evaluated by moral philosophers, with a specific focus on the place our intuitions have in the process. Indeed, the major role that moral intuitions play in evaluating theories of well-being, despite their sometimes dubious epistemic credentials, leads to an in-depth enquiry into their inner workings and potential for containing normatively significant information. The investigation, which draws on the work of Woodward and Allman (2007), concludes that intuitions about unrealistic thought experiments should not play an important role in evaluating theories of well-being. Rather, they should only act as a warning sign, highlighting moral propositions for further analysis. Based on these findings, a new method for assessing theories of well-being is suggested and applied to a specific internalist account of hedonism about well-being to show how the Deceived Businessman and Experience Machine thought experiments lack normative significance, leaving the Argument from False Pleasures without sufficient evidence to be compelling. Indeed, this essay concludes that the Argument from False Pleasures should no longer be thought to provide any good reason to believe that hedonism about well-being is implausible. This result is only one step on the road to reviving hedonism about well-being, but it is a very important one.</p>

Abstract In this paper, we complement proximate or ‘how’ explanations for the origins of language, broadening our perspective to include fitness-consequences explanations, i.e. ultimate, or ‘why’ explanations. We identify the platform of trust as a fundamental prerequisite for the development of a language-like system of symbolic communication. The platform of trust is a social niche in which cheap but honest communication with non-kin is possible, because messages tend to be trusted as a default. We briefly consider the place of the platform of trust on the road map as laid out in the Mirror System Hypothesis. We then turn to recent research on turn-taking in primates, which has been proposed as a precursor of the cooperative structuring of conversation in humans. We suggest, instead, that human turn-taking, in its full richness that makes it an interesting explanatory target, may only appear in a communicative system that is already founded on a community-wide, cooperative platform of trust.
