A Formal Framework for Strategic Representations and Conceptual Reorganization
No full textIn this paper, we introduce a formal language for modeling the structure of strategic representations and operations that conceptualize change on basis of them. Strategic representations are lower dimensional representations of the world, that underlie the understanding of what business environments are, how they may change, and attempts to shape them. We start from discussing known strategic representations like Porter's five forces model or the strategy canvas. We elicit the conceptual structure underlying these representations by capturing them in our formal language. We demonstrate that our formal language can express operations of conceptual change of strategies such as stretching (the extension of value ranges), lifting (deleting dimensions), extending (adding dimensions), amalgamation (enabling new combinations of features by amalgamating different domains), and transferring structure (exploring analogies). These operations can be the basis for strategizing: for seeing possible reorganizations of strategies and even to become aware of new opportunities. We apply these operations to explain classical business cases, including a detailed study of the conceptual structure underling Steve Jobs' digital hub concept. Our formal language is, to our knowledge, the first attempt to capture the variety of conceptual operations underlying strategic change using one comprehensive mode

An exploratory study of heuristics for anticipating prices
No full textPurpose: this research explores how investment and central bankers cope with strategic uncertainty when they anticipate prices. The uncertainty originates from others’ decisions and their consequences, and cannot be meaningfully reduced to risk. We postulate that, in order to cope with this type of uncertainty, bankers use simple rules, also called heuristics. This study aims to identify such heuristics and the psychological processes that underlie them.Design/methodology/approach: we interviewed 22 managers of teams tasked toanticipate prices, in two leading investment and central banks. The primary data came from indepth, semi-structured interviews lasting 30 to 60 minutes, supplemented by our observations during the on-site visits, emails and phone calls when preparing the interviews, and reports published by the banks. Data was coded and heuristics were induced over multiple rounds by multiple researchers.Findings: bankers (1) construct simple game representations of markets, (2) makeinferences to gauge opponents, (3) become alert when they see too much agreement, and (4) communicate coherent narratives. Heuristics (1)–(3) are employed when the pace of decision making is fast, whereas (4) is used for longer time scales. In sum, bankers exhibit reciprocal bounded rationality, wherein interaction partners are mutually aware of and adapted to the fundamental uncertainty of the task and their limited resources.Originality: heuristics for anticipating prices have not been studied empirically outside the lab. The findings may help integrate conceptualizations of heuristics in the simple-rules and fast-and-frugal-heuristics research programs, and improve market efficiency

Nudge, boost, or design? Limitations of behaviorally informed policy under social interaction
No full textNudge and boost are two competing approaches to applying the psychology of reasoning and decision making to improve policy. Whereas nudges rely on manipulation of choice architecture to steer people towards better choices, the objective of boosts is to develop good decision-making competences. Proponents of both approaches claim capacity to enhance social welfare through better individual decisions. We suggest that such efforts should involve a more careful analysis of how individual and social welfare are related in the policy context. First, individual rationality is not always sufficient or necessary for improving collective outcomes. Second, collective outcomes of complex social interactions among individuals are largely ignored by the focus of both nudge and boost on individual decisions. We suggest that the design of mechanisms and social norms can sometimes lead to better collective outcomes than nudge and boost, and present conditions under which the three approaches (nudge, boost, and design) can be expected to enhance social welfare

Ei-ladattavan hybridiauton esilämmitys : vaikutukset järjestelmän toimintakykyyn
No full textTämän opinnäytetyön tarkoituksena oli tutkia ja selvittää sähköisen esilämmityksen vaikutuksia hybridijärjestelmän toimintaan. Työssä tarkasteltiin erityisesti vaikutuksia matkaan joka ajettiin pelkästään käyttämällä sähköä auton hybridiakustosta. Samalla seurattiin auton polttoaineen keskikulutuksen muutoksia. Nämä vaikutukset saatiin parhaiten näkyviin, ajamalla samoja reittejä esilämmitetyllä ja ilman esilämmitystä olevalla autolla sekä vertailemalla näistä saatuja tuloksia.
Työssä käytettävä hybridiauto on tekijän omistuksessa ja omassa käytössä. Autoa käytetään pääsääntöisesti taajamaliikenteessä, mutta myös maantie- ja moottoritienopeuksissa. Ajaminen koostuu tekijän normaalista auton käytöstä. Työhön kuuluu kolme eri vaihetta. Ensimmäisessä vaiheessa autoa esilämmitettiin ennen jokaista kotona suoritettua liikkeellelähtöä, työn tekemisen aikana voimassa olleiden suosituksien mukaisesti. Toisessa vaiheessa autoa ei esilämmitetty ennen ajoon lähtöä. Kolmannessa vaiheessa tulokset kirjattiin muistiin ja analysoitiin.
Hybridijärjestelmän käyttö vähentää polttoaineen kulutusta ja päästöjä verrattuna pelkästään polttomoottorilla varustettuun autoon. Auton esilämmitys parantaa sekä ajoturvallisuutta että mukavuutta, kun lämpötila on pakkasella tai lähellä nollaa. Esilämmitetty moottori saavuttaa nopeammin normaalin käyntilämpötilan verrattuna moottoriin, jota ei ole esilämmitetty ennen ajoon lähtöä. Kun moottori käy normaalilla käyntilämpötilallaan, päästöt ja polttoaineen kulutus pienentyvät verrattuna kylmänä käyvään moottoriin. Myös käynnistyksen päästöjä saadaan pienennettyä esilämmityksellä.
Autolla on ajettu pääsääntöisesti lyhyitä matkoja, jolloin järjestelmän polttomoottori ei ole saavuttanut normaalia käyntilämpötilaansa. Työn tuloksena havaittiin, että esilämmitys vaikuttaa myönteisesti hybridijärjestelmän kykyyn käyttää pelkästään sähkömoottoria auton liikuttamiseen. Tämä tulos on ennakko-odotusten mukainen.The purpose of the thesis was to study the effects of electronic preheating on the operation of a hybrid system. The impact of the trip, which was driven by using only electricity from the car hybrid battery, was specifically examined in this thesis. At the same time, changes in the average fuel consumption of the car were tracked. The effects were best noticed driving the same routes with a preheated car and the car without preheating, and comparing the results.
The hybrid car used in the work is owned and used by the author. The car is mainly used in urban area but also at highway speeds. Driving consists of the author´s normal car use. The work involved three different phases. In the first phase, the car was preheated before each start-up at home, in accordance with the recommendations in force at the time of the work. In the second phase, the car was not preheated before start-ups. In the third phase, the results were reported and analyzed.
Using a hybrid system in a car reduces fuel consumption and emissions compared to a car with an internal combustion engine only. Car preheating improves both driving safely and comfort when the temperature is low or near zero degrees. A preheated engine reaches faster its normal operating temperature compared to an engine that has not been preheated before driving. When the engine is running at its normal operating temperature, emissions and fuel consumption are reduced compared to a cold engine. Start-up emissions can also be reduced by preheating.
The car has been mainly driven for short distances, whereupon the internal combustion engine of the system has not reached its normal operating temperature. The study shows that preheating has a positive effect on the ability of the hybrid system to use only an electric motor to move the car. This result is in line with the expectations
Cittadinanza amministrativa e democrazia partecipativa
No full textThis paper examines the definition of participation focusing on the idea of
administrative participation and the concept of administrative democracy.
Therefore, the author analyses the alteration of citizenship notion as the result of the change in
the relationship between citizens and public administration: the adoption of the law 241/1990 –
together with other laws – and the gradual opening of administrative institutions give new tools to
citizens to create an administrative democracy
Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
