Extensions of representable linear functionals to unitized quasi *-algebras
2013
This paper starts from noting that, under certain conditions, *-representability and extensibility to the unitized *-algebra of a positive linear functional, defined on a *-algebra without unit, are equivalent. Here some conditions for the equivalence of the same concepts for a hermitian linear functional defined on a quasi *-algebra $(\A,\Ao)$ without unit are given. The approach is twofold: on the one hand, conditions for the equivalence are exhibited by introducing a condition for the *- representability of the extension of a *-representable functional to the unitized quasi *-algebra, on the other hand a *-representable extension to the unitization of a hermitian linear functional by mea…
Developing Students Well-Being and Engagement in Higher Education during COVID-19—A Case Study of Web-Based Learning in Finland
2023
COVID-19 rapidly and extensively changed the normal everyday practices of societies, and there is no going back to the past. Universities also had to adapt and re-establish their normal routines, from policies to practices. In this article, we explore university students’ experiences of web-based learning, their well-being, and engagement during the pandemic. As a theoretical framework, we use the concept of the university student engagement inventory (USEI), which includes behavioral, cognitive, and emotional dimensions. The data were collected during the COVID-19 pandemic from university students (N = 35) via an online survey and analyzed using a thematic content analysis. According to th…
Protective and Educational Effects of Physical Activity Practice on Mental Health in Young Age during COVID-19 Lockdown
2022
Background: The restrictions imposed by the COVID-19 pandemic have modified the lifestyle of young people, worsening their mental health. Although some countries were allowed to practice outdoor physical activity (PA) in cases of lockdown, the PA level in the general population decreased. The current study aims to assess the differences in fear of COVID-19, anxiety, neuroticism, and general self-efficacy between university students who practiced PA during the second wave of lockdown and those who did not practice any PA. Methods: The sample consisted of 276 university students (176 females, 63.8%; mean age: 22.13, SD: ±3.94) who answered an online questionnaire detecting life habits …

IEA EBC Annex83 Positive Energy Districts
2021
At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…
Wybrane przykłady realizacji koncepcji miasta-ogrodu oraz możliwości implementacji ich elementów we współczesnej tkance miejskiej
2020
Praca stanowi przekrój myśli urbanistycznej, jaką jest koncepcja miasta- ogrodu. Celem pracy jest przedstawienie sposobu kształtowania współczesnej tkanki miejskiej w odniesieniu do założeń garden city na przykładzie miasta Opole. Obecne tendencje w planowaniu przestrzennym miast zdają się nie uwzględniać szeroko rozumianego krajobrazu jako waloru. Niniejsza praca powstała z myślą o przybliżeniu założeń opartych na zasadzie połączenia środowiska zbudowanego z naturalnym, pokazując, że mogą być one funkcjonalnymi i kompletnymi tkankami miejskimi
Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
Les villes sahariennes algériennes et le développement urbain durable, ville réelle et ville normative
2005
The Algerian Sahara’s urbanization constitutes today an essential data to apprehend the complex spatial dynamics which animate it. In less than fifty years, the Sahara has massively urbanize, upsetting urban morphologies as well as the practices and socio-space relations of the city’s populations. This exceptional population’s increase had for corollary the appearance of multiform tensions on urban spaces. The central question of the evolutions of these urban entities, located in fragile and constraining spaces, arises today with force. The principles of the policies of regional planning, based on the concept of sustainability, bring certain brief replies for the future of these Saharan cit…
Inhibitors, enablers and social side winds Explaining the use of exercise tracking systems
2014
There has been a vast research interest in exercise tracking systems as they are hoped to boost motivation for exercise and thus improve users’ health. However, research activity on actual use and experiences on using such systems has been mild: one has been more interested in the consequences of use than the use itself. To address this gap, we report a study, in which we examined the use of exercise tracking systems (i.e. physical devices with connected services and information systems) in their contexts of use. The study was based on diary data collected in Finland. Analysis of the data was based on a framework describing various techno-determinant inhibitors and enablers of technology us…
Psychological processes of ACL-patients' post-surgery rehabilitation : A prospective test of an integrated theoretical model
2020
Objectives: The aim of this prospective study was to examine the utility of an integrated model comprising constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) in predicting adherence to a post-surgery rehabilitation program in patients receiving anterior cruciate ligament (ACL) reconstruction. Constructs of the integrated model measured at baseline were expected to predict patients' rehabilitation adherence two months later. Method: Patients (N = 121, M age = 27.62, range = 18–53; 36.66% female) scheduled to have ACL reconstruction surgery within two months were recruited from a Hong Kong public hospital. At baseline and two-month follow-up, patients com…
