Abstract:
We prove that for every distribution D on n bits with Shannon entropy ≥ n − a , at most O (2 d a log d +1 g )/γ 5 of the bits D i can be predicted with advantage γ by an AC 0 circuit of size g and depth D that is a function of all of the bits of D except D i . This answers a question by Meir and Wigderson, who proved a corresponding result for decision trees. We also show that there are distributions D with entropy ≥ n − O (1) such that any subset of O ( n / log n ) bits of D on can be distinguished from uniform by a circuit of depth 2 and size poly( n ). This separates the notions of predictability and distinguishability in this context.

Abstract:
Unpredictability in robot behaviour can cause difficulties in interacting with robots. However, for social interactions with robots, a degree of unpredictability in robot behaviour may be desirable for facilitating engagement and increasing the attribution of mental states to the robot. To generate a better conceptual understanding of predictability, we looked at two facets of predictability, namely, the ability to predict robot actions and the association of predictability as an attribute of the robot. We carried out a video human-robot interaction study where we manipulated whether participants could either see the cause of a robot’s responsive action or could not see this, because there was no cause, or because we obstructed the visual cues. Our results indicate that when the cause of the robot’s responsive actions was not visible, participants rated the robot as more unpredictable and less competent, compared to when it was visible. The relationship between seeing the cause of the responsive actions and the attribution of competence was partially mediated by the attribution of unpredictability to the robot. We argue that the effects of unpredictability may be mitigated when the robot identifies when a person may not be aware of what the robot wants to respond to and uses additional actions to make its response predictable.

Abstract:
The present study sought to investigate whether perceived family unpredictability affects the development of life history strategies in both the reproductive and somatic domains by evaluating the ages at which life milestones occurred. In this study 211 young Brazilians answered a 10-item instrument that contained future milestones, the Family Unpredictability in Childhood, and a sociodemographic questionnaire. Not all participants had already achieved the milestones. Earlier ages of giving birth to the first child, marrying, starting a family, and at first formal employment were correlated with greater unpredictability scores. Significant correlations were found more frequently for the participants who had already met the milestones. Data support the importance of the childhood environment for later development. Results suggest that data obtained based on the ages at which milestones occurred and ages at which milestones are expected to occur may present important differences with regard to the influence of environmental factors.

Abstract:
This paper aims to identify the inflection point in financial discourse, the moment of explosion and unpredictability in the 2007–2008 economic crisis, through an analysis of metaphors, and its relation to the concept of jumps in finance. The corpus is formed by articles dating from 2007–2008 published in The Wall Street Journal and related to the movements of the Standard & Poor’s 500 index (S&P500) of the United States. For the purposes of this paper, two texts are analysed: “Traders in Lehman, AIG held out hope – Friday”, and the speech “Four questions about the financial crisis” by Ben S. Bernanke. What is of particular interest is the transformation of unpredictability to predictability, as incorporated in this type of discourse to indicate a predetermined chain of events, chosen from a wide spectrum of possibilities. The theoretical framework draws on Juri Lotman’s views on the concepts of explosion, unpredictability, inflection point and predictability.

Abstract:
The debate covering stock return predictability is now shifted towards the investigation of changing patterns of return predictability as suggested by the adaptive market hypothesis (AMH). The present article inspects the varying return predictability pertaining to the equity market in Pakistan under AMH framework. A nonlinear autoregressive neural network (NARNN) model is employed to investigate the nonlinear dependency of returns over a period of eighteen years. NARNN is a robust and flexible technique that is free from any restrictive assumptions. Under a rolling window framework, the repeating patterns of predictability and unpredictability are observed. This finding confirms the idea of AMH.

Abstract:
Research findings and clinical observations suggest that families with an alcoholic parent are more unpredictable. Alcoholic parents ( n = 25, 68% men, 68% Euro-American, M age = 38.6 yr.) and community parents ( n = 27, 52% men, 70% Euro-American, M age = 38.8 yr.) completed the self-report Family Unpredictability Scale of Ross and Hill. Alcoholic parents reported significantly higher (less predictability) scores on the subscales of Nurturance, Finances, and Discipline, as well as on the Total Family Unpredictability Scale ( ps < .01). This appears to be the first study on family unpredictability and parental alcoholism in which parental reports of multiple dimensions of unpredictability are used. We provide suggestions for research and clinical uses of the scale, especially pertaining to families with an alcoholic parent.

Abstract:
This article re-examines the return predictability of eight African stock markets. When returns of stocks are predictable, arbitrageurs make abnormal gains from analyzing prices. The study uses a non-parametric Generalised Spectral (GS) test in a rolling window approach. The rolling window approach tracts the periods of efficiency over time. The GS test is robust to conditional heteroscedasticity and it detects the presence of linear and nonlinear dependencies in a stationary time series. Our results support the Adaptive Market Hypothesis (AMH). This is because, indices whose returns were observed to be predictable by analyzing them in absolute form and therefore weak - form inefficient showed trends of unpredictability in a rolling window.

Abstract:
AbstractThere is a tendency in contemporary contract law for judges to “never say never” and permit an open-ended exception from the rule. This nebulous exception is designed to cater for the rare instance where application of the rule would be undesirable in the interests of justice. However, this kind of imprecise exception is deleterious in terms of the unpredictability it generates, as well as the attendant increases in time and costs that result. The “never say never” approach is to be discouraged in contract law where commercial predictability, while certainly not inviolable, nonetheless remains a weighty goal deserving of continued deference.

Abstract:
The aim of this experiment was to study the role of (un)predictability in a fear conditioning paradigm: analyzing the differences in both cue and context conditioning. For this reason, we manipulated the presentation of the unconditional stimulus (US) using two conditions: a paired presentation of the US-CS (predictable) and an unpaired presentation of the US (unpredictable). We manipulated the context using the lightning of the experimental room: dark and light conditions. Our dependent variables were the skin conductance response (SCR) and the startle reflex measurement. Participants were 65 students from the University of Leuven. Results showed more context conditioning in the unpaired block (unpredictable) compared to the paired one and cue conditioning in the paired block (predictable).
El objetivo de este estudio fue investigar el rol de la (im)predictabilidad en el paradigma de condicionamiento de miedo, al analizar las diferencias tanto en el condicionamiento específico (cue) como en el contextual. Por consiguiente, se manipuló la presentación del estímulo incondicionado (EI) utilizando dos condiciones: una presentación apareada del EI con el estímulo condicionado —EC en adelante— (predecible) y una presentación no apareada del EI (impredecible). Se manipuló el contexto utilizando la luz central del cuarto experimental: condiciones de oscuridad y claridad. Las variables independientes fueron la respuesta de conductancia de la piel y la medición de la respuesta de sobresalto. Los participantes fueron 65 alumnos de primer año de psicología. Los resultados muestran más condicionamiento contextual en el bloque no apareado (impredecible) comparado con el apareado, y condicionamiento específico en el bloque apareado (predecible).

Abstract:
Background: Primary Healthcare Centers [PHC] represent the first healthcare contact that patients have, unless they are critically ill or their state is life-threathening. Distric nurse´s work in PHC requires preparedness to meet people in different ages and varying cultural and ethnical backgrounds. This preparedness includes an independent and person-centred workway. The study´s theoretical framework therefore proceeds from person-centred care. Challenging encounters occur in district nurse´s meetings with patients. The concept complex healthcare encounters exists in the competence description of the district nurses and in educational regulatory contexts. Despite of this, there is no general definition of the concept and what it is characterized by. Aim: The aim of this study is to describe district nurse´s experiences of complex healthcare encounters. Method: A qualitative, descriptive, inductive content analysis is used as the analysis method. Six focusgroup-interviews were contucted with nurses and districs nurses working in PHC. Results: District nurse´s experiences of complex healthcare encounters contains to balance unpredictable encounters with predictable organizational terms. This is described as: To meet people with varying lifesituations and To care professionally within organizational conditions. Conclusion: District nurses experience complex healthcare encounters characterized by the coexistence of unpredictable meetings with people and predictable organizational terms. By developing the knowledge about complex healthcare encounters, district nurses can streamline the care simultaneously as the mission of the district nurse can be explicated.
Bakgrund: Vårdcentraler är vårdsökandes första vårdinstans om inte vårdbehovet är akut eller livshotande. Distriktssköterskors arbete på vårdcentraler medför beredskap att möta människor i olika åldrar och med varierande kulturella och etniska bakgrunder. Denna beredskap inrymmer ett självständigt och personcentrerat arbetssätt. Examensarbetets teoretiska referensram utgår därmed från personcentrerad vård. Utmanande vårdsituationer uppstår i distriktssköterskors möten med vårdsökande människor. Begreppet komplexa vårdsituationer förekommer i distriktssköterskors kompetensbeskrivande och utbildningsreglerande dokument. Dock saknas en gemensam bild av vad detta begrepp karaktäriseras av. Syfte: Syftet är att beskriva distriktssköterskors erfarenheter av komplexa vårdsituationer på vårdcentral. Metod: En kvalitativ, deskriptiv innehållsanalys med en induktiv ansats har används som analysmetod. Sex fokusgruppsintervjuer med distriktssköterskor och sjuksköterskor som arbetar på vårdcentral har genomförts. Resultat: Distriktssköterskors erfarenheter av komplexa vårdsituationer på vårdcentral innehåller att balansera mellan oförutsägbara möten med människor och förutsägbara organisatoriska villkor. Detta beskrivs som: Att möta människor i varierande livssituationer och Att vårda professionellt med givna organisatoriska förutsättningar. Slutsats: Distriktssköterskorna erfar komplexa vårdsituationer som karaktäriseras av att oförutsägbara möten med människor och förutsägbara organisatoriska villkor samexisterar. Genom kunskapsutveckling om komplexa vårdsituationer kan distriktssköterskor effektivisera vården samtidigt som distriktssköterskors uppdrag förtydligas.

Abstract:
This chapter develops testable hypotheses of when Navigation by Judgment will be more or less successful. It develops theory as to why environmental predictability and project external verifiability play important mediating roles in the relationship between navigation strategy and success. The chapter argues that returns to Navigation by Judgment will rise as environmental unpredictability rises and as task verifiability falls. The chapter also introduces the quantitative and qualitative data that will be used in chapters 6 and 7 and discusses quantitative and qualitative data-collection methods at some length. The chapter also operationalizes for quantitative analysis the key variables, including Project Success, the propensity of international development organizations to Navigate by Judgment, and environmental unpredictability.

Abstract:
This chapter brings quantitative and qualitative empirics to bear on the relationship between environmental predictability, navigation strategy, and international development organization (IDO) Project Success. The chapter first examines quantitative data on IDO Project Success, as environmental unpredictability varies along with the role that the Navigation by Judgment propensity plays in this relationship. It then turns to qualitative cases, which compare U.S. Agency for International Development (USAID) and U.K. Department for International Development (DFID) performance in Liberia’s unpredictable environment as both IDOs attempt to achieve similar goals in health and government capacity-building interventions. The discussion draws on the quantitative Project Performance Database and two pairs of case studies comparing USAID and DFID projects in relatively unpredictable Liberia. The chapter finds that Navigation by Judgment is associated with relatively better project performance in unpredictable contexts.

Abstract:
The unpredictability of Australia’s climate poses real challenges for practices that were developed based on the relative predictability of a European climate. More recently, policy has been moving towards accepting drought as a reality, rejecting the notion that it is a natural disaster in favour of an approach based on risk management. However, the level of public debate during a drought event suggests that this policy approach has not been widely understood or accepted. Media reporting of drought rapidly adopts disaster-related language and the organisation of relief appeals reinforces the impression that drought is an aberration rather than a normal part of Australia’s climate patterns. Beyond Drought provides a multi-disciplinary discussion aimed at increasing the level of understanding of drought’s many facets and its impact on the environment, communities and the economy. It introduces a range of perspectives in order to emphasise the complexity of drought policy. The book cuts through the often emotional debate that occurs during a drought event, aiming to stimulate reasoned discussion about the best way that Australian farmers and the broader community can live with the vagaries of an uncertain climate.

Abstract:
Artificial intelligence evolves rapidly and will have a great impact on the society in the future. One important question which still cannot be addressed with satisfaction is whether the decision of an intelligent agent can be predicted. As a consequence of this, the general question arises if such agents can be controllable and future robotic applications can be safe. This chapter shows that unpredictable systems are very common in mathematics and physics although the underlying mathematical structure can be very simple. It also shows that such unpredictability can also emerge for intelligent agents in reinforcement learning, especially for complex tasks with various input parameters. An observer would not be capable to distinguish this unpredictability from a free will of the agent. This raises ethical questions and safety issues which are briefly presented.

Abstract:
This concluding chapter reviews the central arguments of the book and reflects critically on living with uncertainty and unpredictability as a form of critical mobility for urban living. It considers how the focus on efficiency, data-driven predictability, and control in the narrative about cities over the past two decades strikingly recalls the early days of the twentieth century. What then was the idealized new and modern has become the smart of today. The development of technology has long pursued the superlatives of faster, higher, bigger, cleaner, stronger, better, and safer. This was a promising strategy when the scope and reach of technologies were limited. Today, however, networked information technologies pervade not only cities but also large and intricate parts of our everyday practice.

Abstract:
We present an experimental study on nonlinear dynamics of combustion instability in a lean premixed gas-turbine model combustor with a swirl-stabilized turbulent flame. Intermittent combustion oscillations switching irregularly back and forth between a burst and pseudo-periodic oscillations exhibit the deterministic nature of chaos. This is clearly demonstrated by considering two nonlinear forecasting methods: the extended version [1] of the Sugihara & May algorithm [2] as a local predictor, and the generalized radial basis function network as a global predictor [3], [4]. The former enables us to extract the short-term predictability and long-term unpredictability nature of chaos, while the latter can produce surrogate data to test for determinism as a free running approach. Permutation entropy is estimated by a symbolic sequence approach for the surrogate data to test for determinism and is also used as an online detector to prevent lean blowout.
