Quantifying and easing conflicting goals between interest groups in natural resource planning

2019

Management of natural resources at the regional level is a compromise between a variety of objectives and interests. At the local level, management of the forests depends upon the ownership structure, with forest owners using their forests as they see fit. A potential conflict occurs if the forest owners’ management decisions are counter to the interests of society in general or the industry that relies on the forest resource as their raw material. We explore the intensity of this conflict at the regional level in several large boreal forest production landscapes. To explore the conflict, we investigate three main interest groups: (i) economically oriented forest owners; (ii) industry grou…

Cost-efficiency assessments of marine monitoring methods lack rigor—a systematic mapping of literature and an end-user view on optimal cost-efficienc…

2021

Global deterioration of marine ecosystems, together with increasing pressure to use them, has created a demand for new, more efficient and cost-efficient monitoring tools that enable assessing changes in the status of marine ecosystems. However, demonstrating the cost-efficiency of a monitoring method is not straightforward as there are no generally applicable guidelines. Our study provides a systematic literature mapping of methods and criteria that have been proposed or used since the year 2000 to evaluate the cost-efficiency of marine monitoring methods. We aimed to investigate these methods but discovered that examples of actual cost-efficiency assessments in literature were rare, contr…

Precision, Applicability, and Economic Implications: A Comparison of Alternative Biodiversity Offset Indexes

2021

AbstractThe rates of ecosystem degradation and biodiversity loss are alarming and current conservation efforts are not sufficient to stop them. The need for new tools is urgent. One approach is biodiversity offsetting: a developer causing habitat degradation provides an improvement in biodiversity so that the lost ecological value is compensated for. Accurate and ecologically meaningful measurement of losses and estimation of gains are essential in reaching the no net loss goal or any other desired outcome of biodiversity offsetting. The chosen calculation method strongly influences biodiversity outcomes. We compare a multiplicative method, which is based on a habitat condition index develo…

A survey on handling computationally expensive multiobjective optimization problems with evolutionary algorithms

2017

Evolutionary algorithms are widely used for solving multiobjective optimization problems but are often criticized because of a large number of function evaluations needed. Approximations, especially function approximations, also referred to as surrogates or metamodels are commonly used in the literature to reduce the computation time. This paper presents a survey of 45 different recent algorithms proposed in the literature between 2008 and 2016 to handle computationally expensive multiobjective optimization problems. Several algorithms are discussed based on what kind of an approximation such as problem, function or fitness approximation they use. Most emphasis is given to function approxim…

DESDEO: The Modular and Open Source Framework for Interactive Multiobjective Optimization

2021

Interactive multiobjective optimization methods incorporate preferences from a human decision maker in the optimization process iteratively. This allows the decision maker to focus on a subset of solutions, learn about the underlying trade-offs among the conflicting objective functions in the problem and adjust preferences during the solution process. Incorporating preference information allows computing only solutions that are interesting to the decision maker, decreasing computation time significantly. Thus, interactive methods have many strengths making them viable for various applications. However, there is a lack of existing software frameworks to apply and experiment with interactive …

Hitaan opiskelijan analyysi

2013

Tutkimuksen tarkoituksena oli tutkia luokanopettajaopiskelijan kokemusta opiskelusta ja ymmärtää opiskelussa koettuja jännitteitä. Niitä syntyi ympäristön odotusten ja oman kokemuksen välillä, kun opiskeluissa kesti suunniteltua pidempään. Opiskelun hitaus tuntuu ongelmalliselta, sillä yliopisto-opintoja on pyritty nopeuttamaan ja tehostamaan. Opiskelijoiden haluttaisiin valmistuvan nykyistä nopeammin. Hidas opiskelija määrittyy herkästi epäonnistujaksi, vaikka oma kokemus opiskelusta olisi toinen. Tutkimuksessa kuvattiin autoetnografisella otteella tutkijan omaa opiskelukokemusta. Tutkimusteksti muodostui aineiston ja analyysin vuoropuheluksi; kokemuksen näkyväksi tekeminen, analysointi ja…

A comparative study on campus sustainability in higher education sector in Hong Kong and Finland

2015

This thesis presents a comparative study examining the practices of campus sustainability in Higher Education Sectors between Hong Kong and Finland. Campus sustainability is a trend during the last decade as a result of numerous declarations and meetings for sustainable development in Higher education all over the world. In this thesis, the investigated areas are focused on environmental sustainability and Social sustainability. This study used the content analysis method to analyze public available documents from the selected fifteen Higher education institutions in Hong Kong and Finland. The first stage was a description of the current overall situations of campus sustainability in the tw…

Compression Methods for Microclimate Data Based on Linear Approximation of Sensor Data

2019

Edge computing is currently one of the main research topics in the field of Internet of Things. Edge computing requires lightweight and computationally simple algorithms for sensor data analytics. Sensing edge devices are often battery powered and have a wireless connection. In designing edge devices the energy efficiency needs to be taken into account. Pre-processing the data locally in the edge device reduces the amount of data and thus decreases the energy consumption of wireless data transmission. Sensor data compression algorithms presented in this paper are mainly based on data linearity. Microclimate data is near linear in short time window and thus simple linear approximation based …

The effect of (negative) emotion on pro-environmental behavior : an application of the theory of planned behavior

2016

With climate change becoming ever-present as a huge environmental issue for the modern era to address, pro-environmental behavior (PEB) is becoming an increasingly relevant area. There seems to be a divergence between how different actors try and encourage PEB when using emotion as the motivational tool. Therefore, the current study aimed to explore this effect of (negative) emotion on decision making. The Theory of Planned Behavior (TPB) was used as the theoretical framework, with the primary research aim testing whether emotion affects the theory, and if this is a direct effect on intentions. Within the existing research, environmental values are also found to be potentially linked with t…
