Research on degraded and restituted towns: Overview and state-of-the-art

Both current and historical settlement forms experience evolutionary, permanent changes to their spatial and socio-economic attributes, not seldom accompanied by dynamic functional transformations. The linkage between functionalism and dynamism, in turn, is one of those elements of conventional geographical theory used to explain the phenomena of urbanization and urbification. While urbanization r

Degraded and restituted towns in numbers

Degraded and restituted towns constitute an important element of the contemporary settlement system in Poland. This significance stems from two basic facts: firstly, the relatively large number of such places, and, secondly, the role of restituted towns within the formal-legal dimension of urbanization. The importance of degraded and restituted towns is also shown in the variety of topics undertak

Degraded and restituted towns on maps

The large number of degraded (828) and restituted (240) towns in Poland formed the basis for crafting a chapter on the spatial and temporal distribution of these special settlement forms. By focusing on these two aspects has helped, for one, uncover historical regularities, and, for another, reveal geographical patterns of national urbanization processes. This is largely due to the fact that degra

The concept of urban hibernation: Scientific note

This scientific note aims to briefly introduce the concept of urban hibernation, published recently (September 2015) in an article with the same name in European Planning Studies (Routledge). By outlining some general characteristics, the purpose of this note is merely to put the reader’s attention to this concept, whom we remit to the original article for a comprehensive walk-through. The reason

Flexibility in contract design - is that possible?

Public procurement is widely used in order to incorporate competition into public services. Competition in procurement often leads to efficiency but the process can also raise some problems. While providing the procurement documents you do not know who will be your upcoming partner. Another aspect is how flexibility can be managed in contract design while maintaining a high service quality. The ai

‘Doing it in the right order’ : childless men’s intentions regarding family formation

In high-income countries, parental age at first birth has increased and this postponement increases the risk of involuntary childlessness or having fewer children than desired. This interview study was conducted in Denmark and Sweden among childless men (n = 29) in their last year of an education. The aim was to explore the role of individual and societal factors on fertility decision-making and m

Topology optimization of compliant mechanisms considering strain variance

In this work, compliant mechanisms are designed by using multi-objective topology optimization, where maximization of the output displacement and minimization of the strain are considered simultaneously. To quantify the strain, we consider typical measures of strain, which are based on the p-norm, and a new class of strain quantifying functions, which are based on the variance of the strain. The t

Digital Predistortion for Multiuser Hybrid MIMO at mmWaves

Efficient mitigation of power amplifier (PA) nonlinear distortion in multi-user hybrid precoding based broadband mmWave systems is an open research problem. In this article, we carry out detailed signal and distortion modeling in broadband multi-user hybrid MIMO systems, with a bank of nonlinear PAs in each subarray, while also take the inevitable crosstalk between the antenna/PA branches into acc

Navigating in a Misty Landscape–Perceptions of Supporting a Relative Residing in Supported Housing for People with a Psychiatric Disability

The aim was to explore informal carers’ perceptions of supporting the everyday life of a relative who has a psychiatric disability and resides in supported housing (SH). A qualitative study based on interviews with 12 informal carers was performed, and the data was analyzed with qualitative content analysis. The theme “Navigating in a misty landscape when striving to support a relative with a psyc

Co-introduction of native mycorrhizal fungi and plant seeds accelerates restoration of post-mining landscapes

Grasslands are among the most threatened terrestrial biomes, and habitat conservation alone will be insufficient to meet biodiversity goals. While restoration of indigenous grasslands is a priority, conflict with economic objectives means that incorporation of alternative habitats is necessary to offset grassland loss. With up to 800,000 km2 of land affected by mining globally, there is an opportu

Unveiling the complex effects of direct oral anticoagulants on dilute Russell's viper venom time assays

Introduction: Dilute Russell viper venom time (dRVVT) assays can be affected by direct oral anticoagulants (DOACs), which may cause false-positive results. However, there are conflicting results indicating significant differences between different reagents and DOACs. Objectives: To evaluate the effect of DOACs on dRVVT assays. Material and Methods: Samples were prepared by adding DOAC (dabigatran,

Climate anomalies affect annual survival rates of swifts wintering in sub-Saharan Africa

Several species of migratory swifts breed in the Western Palearctic, but they differ in reproductive traits and nonbreeding areas explored in Africa. We examined survival and recapture probabilities of two species of swifts by capture–mark–recapture data collected in northern Italy (Pallid Swift Apus pallidus in Carmagnola, Turin, and Common Swift Apus apus in Guiglia, Modena) in the breeding seas

Treatment of age-related macular degeneration after cataract surgery : a study from the Swedish National Cataract and Macula Registers

Purpose: To characterize pre- and perioperative factors associated with treatment for wet age-related macular degeneration (wet AMD) after cataract surgery. Methods: This register-based cohort study with data from the Swedish National Cataract Register (NCR) and the Swedish Macula Register (SMR) from 2010 to 2017 compared eyes with and without preoperative AMD that had undergone cataract surgery a

How Can We Make Disaster Management Evaluations More Useful? An Empirical Study of Dutch Exercise Evaluations

The evaluation of simulated disasters (for example, exercises) and real responses are important activities. However, little attention has been paid to how reports documenting such events should be written. A key issue is how to make them as useful as possible to professionals working in disaster risk management. Here, we focus on three aspects of a written evaluation: how the object of the evaluat

Spherical Wave Array Based Positioning for Vehicular Scenarios

Smart vehicles are emerging as a possible solution for multiple concerns in road traffic, such as mobility and safety. This work presents radio localization methods based on simultaneous direction of arrival (DOA), time-delay, and range estimation using the SAGE algorithm. The proposed methods do not rely on external sources of information, such as global navigation satellite systems (GNSS). The p

Measuring the migration of surgical specialists

Background: The lack of access to essential surgical care in low-income countries is aggravated by emigration of locally-trained surgical specialists to more affluent regions. Yet, the global diaspora of surgeons, obstetricians, and anesthesiologists from low-income and middle-income countries has never been fully described and compared with those who have remained in their country of origin. It i

Psychometric evaluation of the Chinese version of the Person-Centred Care Assessment Tool : Evaluation of the Chinese version of P-CAT

Objective: This study aims to test a Chinese cross-cultural adaptation of the English version of the Person-Centred Care Assessment Tool (P-CAT)and evaluate its psychometric properties. Design: P-CAT was translated/back-translated using established procedures before the psychometric evaluation of the Chinese version was made. Setting: Two hospitals covering urban and suburban areas of Kunming in tOBJECTIVE: This study aims to test a Chinese cross-cultural adaptation of the English version of the Person-Centred Care Assessment Tool (P-CAT) and evaluate its psychometric properties.DESIGN: P-CAT was translated/back-translated using established procedures before the psychometric evaluation of the Chinese version was made.SETTING: Two hospitals covering urban and suburban areas of Kunming in th
