Adult Lactose Tolerance Is Not an Advantageous Evolutionary Trait
2004
To the Editor. I read with great interest the recent article from Fomon1 in which he refers to the well-known hypothesis that views the variable frequencies of lactase persistence in different human populations and, consequently, the possibility for some adults to feed on milk (lactose tolerance) as an advantageous evolutionary trait that has been genetically determined and brought about through centuries of natural selection. This notion stands as a common statement in current medical literature, and most authors have accepted its validity since the 1970s.2,3 Because adult mammals are lactose-intolerant, this hypothesis is, moreover, based on the low percentage of lactose malabsorption and…
Recognition and Civic Selection
2021
Large-scale immigration and the refugee crisis have caused many states to adapt ever stricter civic selection processes. This paper discusses the challenges arising from civic selection from the perspective of recognition theories. The argument is that recognition theories provide good conceptual tools with which to critically analyze civic selection and immigration. However, the paper also aims to highlight that many current institutional practices are problematic from the perspective of recognition. In the context of civic selection, it is helpful to understand recognition as something that comes in two analytically distinct modes: horizontal (or interpersonal) and vertical (or institutio…
Will collaborative partners’ selection enhance sustainability performance of firms? An empirical study
2015
Main purpose of this paper is to study the role of collaboration for sustainability, in success of business performance. Businesses can have collaborations with many players such as suppliers, logistics operators, clients, intra- and inter-departmental collaborations, for various purposes including the sustainability. We use qualitative approach, mainly semi-structured interviews to understand various dimensions of collaboration namely sharing of valuable information, physical resources both tangible and intangible. We try to understand the collaborative relationships of focal companies under study with its suppliers, buyers and logistics partners. Further, we will study the impact of colla…
Polish local democracy in crisis? Non-competitive elections and the supply of candidates for councillors
2022
Competitive elections are the basis of democracy; without them there is no freedom of choice. Elections without competition are associated with the façade nature of elections in undemocratic systems. There are, however, exceptions to the belief that in a democratic system every election must be competitive. We can also observe them in Poland, particularly in small communes with up to 20,000 inhabitants. They take two forms: non-competitive elections of commune leaders and councillors. The latter case is known in the literature under the legal term of filling seats without voting. In 2018, as many as 8% of Polish councillors obtained their mandate without votes. In 2018 compared to 2014, the…
One-Dimensional Convolutional Neural Networks Combined with Channel Selection Strategy for Seizure Prediction Using Long-Term Intracranial EEG
2022
Seizure prediction using intracranial electroencephalogram (iEEG) has attracted an increasing attention during recent years. iEEG signals are commonly recorded in the form of multiple channels. Many previous studies generally used the iEEG signals of all channels to predict seizures, ignoring the consideration of channel selection. In this study, a method of one-dimensional convolutional neural networks (1D-CNN) combined with channel selection strategy was proposed for seizure prediction. First, we used 30-s sliding windows to segment the raw iEEG signals. Then, the 30-s iEEG segments, which were in three channel forms (single channel, channels only from seizure onset or free zone and all c…
Winter male plumage coloration correlates with breeding status in a cooperative breeding species
2007
The function of colored ornaments is usually related to the signaling of individual quality in intra- and intersexual interactions. In cooperative breeding species, where only a fraction of the male population access the breeding status and the other fraction has the option to help breeding pairs, colored traits might provide the females with a reliable information on the quality of potential mate. Males of the cooperative breeding azure-winged magpies (Cyanopica cyanus) display conspicuous blue plumage coloration. Here we explored the role played by structural blue coloration of males and the probability of becoming a breeder or a helper. Birds were trapped during 4 consecutive years, and …
Market Entry and Priority of Small and Medium-Sized Enterprises in the Software Industry: An Empirical Analysis of Cultural Distance, Geographical Di…
2007
This paper investigates the influence of cultural distance, geographical distance, and three market size variables to the target country preference of SMEs in the software industry. In addition, we examine the shift of priorities in SMEs’ country selection by analyzing how these factors impact the selection of the first, second, and third target countries. Empirical findings of this study suggest that almost 70% of country choices can be explained by software market size and geographical distance alone. The findings adduced also that entry priority of SMEs shifts very fast from countries within a short geographical distance to countries with high purchasing power and within a greater geogra…
Criteria for selecting children with special needs for dental treatment under general anaesthesia
2007
Objective: To study criteria for helping to select children with special needs for dental treatment under general anaesthesia. Materials and methods: Group of 30 children (aged under 18) examined on the Course at the Universidad Complutense de Madrid (UCM) (Specialisation on holistic dental treatment of children with special needs) and subsequently referred to the Disabled Children’s Oral Health Unit (DCOHU) within Primary Health Care Area 2 of the Madrid Health Service (SERMAS) where dental treatment under general anaesthesia was given during 2005. Relevant data were taken from their case histories with regard to their general health, oral health and behaviour. Results: In most of the chil…
