No effect of lack of wood for acorn ant colonies development

2021

Acorn ants mostly inhabit cavities in fallen twigs and hollow acorns. Such places, e.g., dead wood, provide an attractive living resource for many groups of microorganisms, like fungi and bacteria, which can be important for ants. However, during experiments in laboratories, acorn ant colonies are typically kept without dead wood. During laboratory experi-ments, the preferences of the ant Temnothorax crassispinus for nest sites with pieces of dead wood were checked, and whether the presence of such wood influenced productivity. In binary choice tests, colonies had to choose a nest site when presented with two potential nest sites, one empty, or two cavities with different contents. The ant …

Studies in organic mass spectrometry. Part 17—Formation of phenol radical ions by rearrangement of the molecular ions of someN-arylthiophenecarboxami…

1995

It has been shown by exact mass measurements and collision-induced dissociation mass-analysed ion kinetic energy spectra that the structure of the m/z 124 ion observed in the mass spectra of N-(4-methoxyphenyl)thiophene-2-carboxamide, N-(4-methoxyphenyl)thiophene-3-carboxamide, N-(4-methoxyphenyl)-5-nitrothiophene-3-carboxamide and N-(4-methoxyphenyl)benzamide is identical with that of the molecular ion of 4-methoxyphenol. This ion becomes abundant in metastable energy window reactions. A probable mechanism for its formation is discussed.

Estudio de la relación entre miembros del comité editorial de las revistas científicas de Psicología y su producción según diferentes indicadores bib…

2017

[ES]: El objetivo del presente trabajo es estudiar la relación entre los miembros del comité editorial que publican artículos en revistas de las que forman parte y la propia revista. Los resultados apuntan que los miembros del comité editorial publican sus artículos de forma más rápida frente a los autores que no forman parte del comité, y que no existe colaboración entre los miembros con mayor presencia en diferentes comités, sí habiéndola entre miembros de una misma revista. En 6 de las 10 revistas estudiadas el porcentaje de artículos firmados por algún miembro del comité supera el 25%, y en tres de estas revistas el tiempo de publicación de estos artículos es significativamente inferior…

BUSINESS CAPABILITIES AND HR KNOWLEDGE’ AS THE CRITICAL FACTOR OF DUE DILIGENCE IN PRE-ACQUISITION PHASE

2016

Previous theoretical research has argued that due diligence in the pre-acquisition phase is traditionally oriented towards legal and financial matters. However, in the innovation-driven market environment, where firms need to maintain competitive strength, business skills and knowledge play important roles. Despite this difference, the due diligence research continues in traditional areas, e.g., financial history, legal and commercial liabilities, and tax issues. Hence, the problem may arise in acquirers overpaying or mistakenly rejecting a target firm. There is a need for assessing ‘Business Capabilities and Human Resources Knowledge’ for due diligence in the pre-acquisition phase. Based o…

Some Quantitative Aspects of Stability Management Strategy in a Bank

2012

Abstract The stability of commercial bank system is the result of balanced development, which can be characterised by equilibrium and security over a longer period of time. The history of commercial bank system development indicates that reaching and sustaining this qualitative and quantitative state requires regulations and management. One of the most important parts of commercial bank management system is correctly chosen strategy in the circumstances of a changing environment. Strategy gives a possibility to look into the future of the commercial bank, forecast its goals, areas, scale and potential operational results in relation to resource sources and expenses. Nowadays a commercial ba…

On Capturing Rent from a Non-Renewable Resource International Monopoly: A Dynamic Game Approach

2005

In this paper we model the case of an international non-renewable resource monopolist as a dynamic game between a monopolist and n importing countries governments, and we investigate whether a tariff on resource imports can be advantageous for the consumers of the importing countries when the monopolist sets the price and the importing countries governments act in a non-cooperative way. We find that a tariff is advantageous for the consumers even when there is not commitment to the trade policy although the part of the rent that can be reaped by the importing countries decreases substantially with the number of importing countries. The optimality of the tariff in our dynamic game is explain…

Facilitating climate change adaptation through communication:Insights from the development of a visualization tool

2015

Climate change communication on anticipated impacts and adaptive responses is frequently presented as an effective means to facilitate implementation of adaptation to mitigate risks to residential buildings. However, it requires that communication is developed in a way that resonates with the context of the target audience, provides intelligible information and addresses perceived barriers to adaptation. In this paper we reflect upon criteria for useful climate change communication gained over a three year development process of a web-based tool – VisAdapt™ – aimed at increasing the adaptive capacity among Nordic homeowners. Based on the results from continuous user-testing and focus group …

Coordination games with asymmetric payoffs: An experimental study with intra-group communication

2020

Abstract Two alternative modes of reasoning in coordination games are prominently discussed in the literature: level-k thinking and team reasoning. In order to differentiate between the two modes of reasoning, we experimentally investigate payoff-asymmetric coordination games using an intra-group communication design that incentivizes subjects to explain the reasoning behind their decisions. We find that the reasoning process is significantly different between games. In payoff-symmetric games, team reasoning plays an important role for coordination. In payoff-asymmetric games, level-k reasoning results in frequent miscoordination. Our study clearly illustrates how small differences between …

Social Animation in Complex Environments

2007

This work presents a market-based social model to produce good quality behavioral animations for groups of intelligent virtual agents. The social model coordinates the activities of groups of virtual characters and also includes social actions in the agent decision-making. We follow the Multi-Agent Resource Allocation approach presented in [2], where agents express their preferences using utility functions. The dynamics of social interactions is inspired by the theory of Piaget [3] over which we have implemented reciprocal task exchanges.
