Impacts of reduced Lepidurus arcticus availability on brown trout life history traits in a mountain reservoir
2020
Lepidurus arcticus (the Arctic tadpole shrimp) is a vulnerable keystone species in Arctic and alpine water bodies where its occurrence and population size may influence the viability and life history traits of resident salmonids. Using data from a Norwegian mountain hydropower reservoir, Aursjoen, we illustrate how reduced availability of L. arcticus as prey resulted in the reduced condition, growth and delayed maturation of resident brown trout (Salmo trutta). We further link changes in the relative abundance of L. arcticus as prey to changing reservoir conditions, e.g. water level changes in the spring period, thereby establishing an indirect link between reservoir operation regimes and b…
Effects of Inequality on Trust and Reciprocity: An Experiment With Real Effort
2021
The purpose of this paper is analyzing whether trust and reciprocity are affected by how rich the partner is or how well the partner performed several tasks with real effort. A trust game (TG) experiment is designed with three treatments. First, a baseline Treatment B in which subjects play a finitely repeated TG. Second, in a Treatment H with history, subjects know the partner’s wealth level reached in the past. Third, in a Treatment E with effort the individual endowment with which the TG is played is endogenous and results from the subject’s performance in three different real effort tasks (maths, cognitive and general knowledge related). The data analysis highlights the importance of pa…
Influence of brand image of a sports event on the recommendation of its participants
2020
The aim of this research is to test the psychometric properties and relationships of a model where, from brand congruence of a sport event, trust and commitment to it can be generated, influencing future behavior of participants and resulting in a higher recommendation also called Word of Mouth (hereinafter WOM). A quantitative approach has been carried out by means of a validated questionnaire with Likert-type responses, and data were analyzed with the EQS 6.4 software. The findings indicated that the model is adequate, and also confirm that from congruence, we can explain, at a theoretical level, 45% of trust, and in the same way, from the congruence and trust, we can explain 67% of the c…
Prejudice and need for relatedness expressed in the narratives of Finnish Roma early school leavers: A multi-case study
2023
AbstractSchool discontinuation in Finland is more common among the Finnish Roma than among the population as a whole. We lack knowledge of the perspective of those of the Roma, representing a minority inside a minority, who have left compulsory school without a leaving certificate. Within a study about school experiences of imprisoned early school leavers in Finland we had six participants with a Finnish Roma background, whose experiences of relatedness, and frustration of it, we examine in this paper. We conducted narrative interviews with the participants, applying a co-operative narrative interpretation to the meanings of what was told. After the field process, we interpreted the narrati…
Revisiting the Narratives of Finnish Early School Leavers: Mapping Experiences of Detachment through a Self-determination Theory Lens
2022
Basic psychological needs and people’s experiences affect the choices they make, and further shape the trajectories followed through school. The present study focuses on the perspectives of people who left school without graduating. Through narrative interviewing processes we collected the storied experiences of eleven imprisoned early school leavers in Finland. We triangulated data-driven themes and used as theory the concept of three basic psychological needs: autonomy, competence, and relatedness. Of these, relatedness was the most common and a shared topic brought forth by the participants. Experiencing dissatisfaction and frustration as a result of the need for relatedness played a cru…
The basic psychological needs in physical education scale in Filipino
2013
The Basic Psychological Needs in Physical Education Scale (BPNPE Scale: Vlachopoulos, Katarzi, & Kontou, 2011) is a short instrument grounded in Self-Determination Theory (Ryan & Deci, 2000; 2002), designed to measure fulfillment of students’ basic needs for competence, autonomy, and relatedness in physical education context. The Greek version of this instrument has been reported to have adequate factor structure and strong internal reliability. Instruments developed in other culture need to be examined using a sample from the target culture in order to establish its cultural utility. The primary aim of this study was to explore the factor structure, construct validity, and reliability of t…
Jättikatkan (Gammaracanthus lacustris) ja jäännehalkoisjalkaisen (Mysis relicta) koko- ja tiheysjakaumat Saimaan Paasivedellä; Vertical size and dens…
2010
The ecology of relict crustaceans in Finnish lakes is quite poorly known. In this study we investigated the vertical distributions of these species in Lake Saimaa in the depth zones between 30 m and 60 m. We found out that Gammaracanthus. lacustris lives mainly in the deepest parts of the lake, while Mysis relicta favours the shallowest zones. The average length of both species increased with the depth in the study area. There were some differences in distributions between years, but the main reasons for that are not known exactly. peerReviewed

2010
We examined the diel vertical migrations of the macroscopic pelagic relict crustaceans Gammaracanthus lacustris, Mysis relicta, Monoporeia affinis and Pallaseopsis quadrispinosa in the deep Lake Paasivesi basin of the Saimaa lake complex. The samples were collected in October 2006 and 2007 using a Hydro-Bios Multi Plankton Sampler onboard the research vessel R/V Muikku. The study provides information about the day-and-night and year-to-year changes in the vertical distribution of these crustaceans. Regarding G. lacustris we explored if body size (length), sex or maturity have bearing on the individuals' depth preference or possible diel migrations. We noticed that G. lacustris females occur…
Behaviours and Beliefs Related to Whistleblowing Against Doping in Sport: A Cross-National Study.
2022
BackgroundWhistleblowing has been recognized as an important deterrent of doping in elite competitive sport. The present study examined athletes’ knowledge of external whistleblowing channels and on how and where to report doping misconduct, perceived trust in different whistleblowing reporting channels, whistleblowing behaviour and athletes’ reasons for reporting (or not) doping misconduct.MethodsAthletes from Greece (n = 480), the Russian Federation (n = 512) and the United Kingdom (n = 171) completed a structured questionnaire on demographics, knowledge of different whistleblowing channels, perceived trust in internal and external whistleblowing channels, past whistleblowing behaviour an…
Strategic Cyber Environment Management with Zero Trust and Cyber Counterintelligence
2022
Organisations need to improve their information security practices, given the volume of successful cyberattacks and crimes. To enhance security in an organisation, information security must be considered a business issue, instead of a technical problem. Hence, organisations must change the security protocol from reactive action to proactive operation; must develop information security strategies that support the business; should implement better controls, systems, and services; and must create a process to proactively gather information about the possible threats and adversaries. This study proposes a novel method for combining a zero-trust strategy with cyber counterintelligence to gain th…
