Polls, Coalition Signals, and Strategic Voting: An Experimental Investigation of Perceptions and Effects
No full textThe paper investigates how poll information and coalition signals affect strategic voting, defined as casting a vote for a party other than the most preferred party to better influence the election outcome. In particular if the outcome of an election is perceived to be close, voters in multi-party systems with proportional representation and coalition governments should have an incentive to cast a vote for the party that best influences the formation of the next government. The study focuses in particular on voters’ attention to and perception of polls and coalition signals sent by parties before elections. The study used an innovative design that embedded a laboratory experiment in two real election campaigns, allowing the manipulation of poll results and coalition signals in a realistic environment. The findings suggest that political sophistication plays a crucial role for the accurate perception of polls and strategic voting. Coalition signals are found to have a surprisingly strong effect on (apparently) strategic voting.
G.N. Itz: Stadsbouwmeester van Dordrecht 1832-1867
No full textDit boek bespreekt het leven en werk van G.N. Itz, stads bouwmeester van Dordrecht en zijn positie binnen de architectuurstromingen van de eerste helft van de negentiende eeuw. Een tijdvak dat tot nu toe in de architectuurgeschiedenis weinig aandacht heeft gekregen. G.N. Itz heeft vele bouwwerken ontworpen die heden ten dage nog het aanzicht van Dordrecht bepalen. Zo is de Korenbeurs en de Oud-Katholieke Kerk St. Maria Maior van zijn hand. Mede door de vele illustraties geeft dit boek een goed overzicht van de ontwerpen van G.N. Itz.Architectur
Evaluation of the tissue response of organic, metallic, ceramic and osteoceramic tooth roots
No full textFour classes of materials, inert organic, inert metal, inert ceramic and biologically-active osteoceramic were implanted in the edentulous mandibles of dogs. Tissue response was evaluated at 3, 6, 9, 12 and 18 months by light microscopy; microradiography; clinical evaluation for mobility, rotation, bleeding and radiography; and epi fluorescent analysis of bone growth labels. The pyrolytic carbon implants were not osseous integrated. The bone contact area of the sapphire and titanium alloy implants increased to 60 and 80%, respectively, at 12 months; but decreased to 20% and 60% at 18 months. The area for the osteoceramic was 80% at three months and remained at that level. These results indicate superior tissue response for the osteoceramic material, a ceramic composite of Ca-3(PO4)(2) and MgAl2O4.PT: S; CR: ALBREKTSSON T, 1988, J PERIODONTOL, V59, P287 BAGAMBISA FB, 1990, INT J ORAL MAXILLOF, V5, P217 BLOCK MS, 1990, J ORAL MAXIL SURG, V48, P174 BRUNSKI J, 1988, CDAJ, P66 CARLSSON L, 1994, J ORTHOPAED RES, V12, P274 COOK SD, 1987, INT J ORAL MAXILLOF, V7, P485 DEGROOT K, 1980, BIOMATERIALS, V1, P47 DENISSEN HW, 1986, CURRENT PRACTICE SER, V29, P372 GOTTLANDER M, 1992, CLIN ORAL IMPLAN RES, V3, P71 GOTTLANDER M, 1992, INT J ORAL MAXILLOF, V7, P485 JANIKOWSKI T, 1969, P IOWA ACAD SCI, V76, P113 JARCHO M, 1977, J BIOENG, V1, P70 JOHNSON BW, 1992, J CALIF DENT ASSOC, V20, P33 MCGEE TD, 1974, 3787900, US MCGEE TD, 1974, J BIOMED MAT RES S, V5, P137 MCGEE TD, 1995, ENCY HDB BIOMATERIAL, V1, P69 MCGEE TD, 1995, ENCY HDB BIOMATERIAL, V2, P1413 MCKINNEY RJ, 1982, J ORAL IMPLANT, V10, P619 MEFFERT RM, 1985, IOWA SOC PERIOD 0301 MEFFERT RM, 1987, INT J PERIODONT REST, V4, P9 SCHNITMAN PA, 1993, J AM DENT ASSOC, V124, P39 STILLMAN N, 1993, J AM DENT ASSOC, V124, P51 TWEDEN KS, 1987, THESIS IOWA STATE U VERHEYEN CCPM, 1993, J BIOMED MATER RES, V27, P433 WEINLANDER M, 1992, INT J ORAL MAXILLOF, V7, P491; NR: 25; TC: 3; J9: MATER SCI FORUM; PG: 20; GA: BM15ESource type: Electronic(1

No full textEmpathy under arrest? : functional and structural neural correlates of empathy in psychopathy
No full textOm interacties met anderen goed te laten verlopen, is het belangrijk dat we begrijpen wat zij doen en ervaren. Uit onderzoek is gebleken dat een van de mogelijke mechanismen hierachter ligt in het ‘heractiveren’van hersengebieden - die we gebruiken om acties uit te voeren en emoties en aanrakingen te ervaren - wanneer we anderen waarnemen die deze handelingen uitvoeren of emoties en aanrakingen ervaren. Deze ‘heractivatie’ van hersengebieden zou ons een soort privé ervaring van het gevoel van een ander kunnen geven. Neem als voorbeeld van de pijn die we zelf voelen, wanneer we iemand anders zien die zich in de vinger snijdt. In dit proefschrift onderzochten we het neurale mechanisme dat hieraan ten grondslag ligt bij een groep mensen gediagnosticeerd met psychopathie. Een belangrijk kenmerk van deze mentale stoornis is het verminderd vermogen om mee te voelen met de emoties van anderen en deze te herkennen. Wij hebben in dit onderzoek bekeken of dit samenhangt met een vermindere activatie van de hersengebieden voor emoties, acties en sensaties, wanneer mensen met psychopathie kijken naar andere mensen die iets meemaken. De resultaten van dit proefschrift suggereren dat psychopathie niet zozeer een onvermogen is om deze gebieden te activeren, maar wel dat zij dit spontaan minder sterk doen. Aangezien het de eerste keer is dat soortgelijk onderzoek is uitgevoerd bij deze doelgroep, zullen de resultaten nog moeten worden geverifieerd in vervolgonderzoek. Deze informatie zou dan mogelijk kunnen leiden tot alternatieve therapeutische strategieën.
Emotions of other people are very contagious. Imagine you are a scientist, giving a lecture about the results of your work. While walking up and down the stage, enthusiastically explaining your findings, you forget to pay attention to your feet, stumble, and disappear behind the table. A case-study, completed by the author of this thesis, revealed that gasps will immediately emerge from the audience and when you get up and peer out over the table, many of those that were sitting in the front row will by now have walked a few steps towards you to check whether you are ok (data not published).
The example above indicates that emotions and feelings of others can touch us in a very real way: when someone you see is feeling hurt, there is a big chance that some of this hurt spills over to you as well. In the neuroscientific literature, this phenomenon has been shown at the neural level: When you observe other people perform actions or experience emotions or sensations, this activates brain regions that you would normally use to perform these actions and experience these emotions and sensations yourself.
In this thesis, we examined the mechanism behind this sharing at the neural level, using functional and structural Magnetic Resonance Imaging. More specifically, we were interested in a group of people with a documented lack of responses to emotions of others, namely individuals diagnosed with a disorder called psychopathy. Results from this thesis suggest that psychopathy is not so much an inability to empathize with other people, but a reduced propensity to do so. This information may lead to alternative therapeutic strategies, given that they can be replicated and extended in future research.

No full textDeleting collected digital evidence by exploiting a widely adopted hardware write blocker
No full textAbstractIn this primary work we call for the importance of integrating security testing into the process of testing digital forensic tools. We postulate that digital forensic tools are increasing in features (such as network imaging), becoming networkable, and are being proposed as forensic cloud services. This raises the need for testing the security of these tools, especially since digital evidence integrity is of paramount importance. At the time of conducting this work, little to no published anti-forensic research had focused on attacks against the forensic tools/process. We used the TD3, a popular, validated, touch screen disk duplicator and hardware write blocker with networking capabilities and designed an attack that corrupted the integrity of the destination drive (drive with the duplicated evidence) without the user's knowledge. By also modifying and repackaging the firmware update, we illustrated that a potential adversary is capable of leveraging a phishing attack scenario in order to fake digital forensic practitioners into updating the device with a malicious operating system. The same attack scenario may also be practiced by a disgruntled insider. The results also raise the question of whether security standards should be drafted and adopted by digital forensic tool makers
Process Integration Study of a Poultry Processing Plant
No full textThis paper presents the results of a process integration study of
a poultry processing plant. The Pinch Methodology was utilized
to set targets for process energy use and to critique previous
attempts at energy conservation in poultry plants. It was found
that not all the energy conservation measures previously
implemented in the plant were conducive for minimum energy
design. This study revealed that designing a poultry plant for
minimum energy use is possible with currently available
techniques. Further, existing plants can be retrofitted to improve
process energy use easily. Most significant is the minimum
energy design target for a process that has been studied very
thoroughly in the past. This target answers the question, how
much better could the poultry process be?
The author has also found that the Pinch Methodology can be
easily programmed on a spreadsheet. Many energy conservation
engineers have shied away from Pinch analyses in the past.
However, it is a very useful tool that can be easily applied after
the initial inertia of training is overcome
