This report examines the decision to not get vaccinated (yet) from the perspective of the unvaccinated. That is, obviously, no one is avoiding vaccination because they do not value their health or the health of others. So: what are the primary reasons for the choice to not get vaccinated (yet), from the perspective of those not getting vaccinated? In order to get at this critical issue, for the two waves of our survey conducted April through July, we included closed and open ended survey questions. We focus on 6 categories of answers that people might provide:Life constraints – For example, unable to get to a location to get vaccinated; employment circumstances do not permit taking time off to get the shot(s), or to accommodate side effects.Perception of benefit – Perception that COVID does not pose a major risk to them.Perception of risk – Affirmative beliefs that the vaccine poses a health risk.Uncertainty regarding the risks the vaccine poses – In particular, because of the newness of the vaccines, faster-than-usual development times, and/or lack of testing.Lack of trust in institutions – That the various institutions attesting to the safety of the vaccines are not to be trusted.Fear of needles – That the respondent’s fear of needles is deterring them from getting vaccinated.

Internet of Things (IoT) learning involves the acquisition of transversal skills ranging from the development based on IoT devices and sensors (edge computing) to the connection of the devices themselves to management environments that allow the storage and processing (cloud computing) of data generated by sensors. The usual development cycle for IoT applications consists of the following three stages: stage 1 corresponds to the description of the devices and basic interaction with sensors. In stage 2, data acquired by the devices/sensors are employed by communication models from the origin edge to the management middleware in the cloud. Finally, stage 3 focuses on processing and presentation models. These models present the most relevant indicators for IoT devices and sensors. Students must acquire all the necessary skills and abilities to understand and develop these types of applications, so lecturers need an infrastructure to enable the learning of development of full IoT applications. A Web of Things (WoT) platform named Labs of Things at UNED (LoT@UNED) has been used for this goal. This paper shows the fundamentals and features of this infrastructure, and how the different phases of the full development cycle of solutions in IoT environments are implemented using LoT@UNED. The proposed system has been tested in several computer science subjects. Students can perform remote experimentation with a collaborative WoT learning environment in the cloud, including the possibility to analyze the generated data by IoT sensors.

The usual development of OE [ɑld] in words such as old in Scots is to auld, reflecting the development of this sequence in northern dialects more generally. But in some Scots dialects other pronunciations of these words, reminiscent of dialects of English south of the Ribble–Humber Line, are found. These forms, of the type owld, are found across Lowland Scotland, with particular concentrations in the far north and southwest. Origins in Irish English and English in England have been suggested for this feature of Scots but these hypotheses have not been explored. Aitken & Macafee (2002: 61–2) instead argue for an endogenous origin of both auld and owld, but this proposed double endogenous development of OE [ɑld] is problematic in a number of ways. In this article, I examine the history of these developments in Scots in comparison to their development in dialects of English in England and Ireland. The lack of evidence for the owld development in Older Scots suggests that these forms are of relatively recent origin. Crucially, the Eighteenth-Century English Phonology Database (ECEP) reveals that the owld pronunciations were in fact a feature of early forms of Standard English. Furthermore, several characteristic features of Irish English have spread into southwest Scotland, and the distribution of owld forms in the area fits this pattern. Thus Scots forms such as owld are not the result of endogenous development, but have their origin in English, in the case of southwest Scotland at least in part from Irish English, and elsewhere in Scotland from early forms of Standard English. These owld forms have been ‘localised’ and reinterpreted as ‘Scots’, alongside or replacing original auld. The analysis of the origins of this feature highlights not only the role of contact with varieties of English in the development of Scots, but also the importance of sources such as the ECEP database for understanding the historical phonology of Scots and English.

AbstractWhilst, in many countries, the scale of forest loss from business-as-usual development is immense, in Poland, this problem does not exist. However, obtaining additional land areas for afforestation is a main issue in Poland. In Poland, after the World War II, the forest area has been systematically growing. In 1945, the forest area was about 6.5 million ha, and the forest cover was 21%. In 2016, the forest area reached 9.2 million ha, and forest cover amounted to 29.5%. Today, there are 0.24 ha of forests per one inhabitant of Poland. The size of wood resources in stands is also changing. In 1945, forest resources on the trunk amounted to approximately 906 million m3, and in 2016, it reached 2.4 million m3. The problem, however, is the uneven distribution of forests in Poland. Forests in Poland are very strictly protected by law. There are two most important acts, Forest Act of 2001 and Nature Conservation Act of 2004, that regulate principles for the retention, protection and augmentation of forest resources. Over the past decades in Poland, the social demands regarding non-economical functions of forest such as recreational activities, soil and water protection and mitigation of global warming became an important and constantly growing challenge for forest managers. Thus we suggest that, first of all, it is very important to extract the leading function for a given forest area. Interactions between development and conservations policies are very tied and may suggest the need of their integration. In this article, we present the concept of development policy for forest management and forest protection in Poland.

<p>Schwannomas are benign tumors, usually solitary, encapsulated, slow-growing, which have their origin in differentiated neoplastic Schwann cells with extramedullary intradural usual development related to nerve roots. The melanotic schwannoma is a variant of these tumors whose location in almost one third of cases is on the posterior spinal nerve root, with a nonspecific clinical presentation. Magnetic resonance imaging is the most widely used test for the diagnosis, revealing hyperintense T1-weighted sequences and hypointense T2-weighted sequences. Diagnostic confirmation is obtained by histological and immunohistochemical studies, in which there is intense cytoplasmatic pigmentation. There are two distinct types of melanotic schwannomas: sporadic and psammomatous, the latter related to the called Carney complex, a form of multiple endocrine neoplasm with familiar character. In literature we found few cases of these neoplasms, the largest series consisting of five cases. The objective of this study is to report a rare case of melanotic schwannoma of the lumbar spine of the sporadic type of extramedullary location. We also present a brief review of the literature containing the main characteristics of the tumor, including its different forms, differential diagnoses, data from histological and immunohistochemical studies as well as the currently recommended approach in order to contribute to a better understanding of this neoplasm.</p>

The goal of this study was to test 2 hypotheses about language development in pediatric cochlear implant (CI) users. The “language instinct” hypothesis states that children with CIs will develop language in the same sequence as children with normal hearing, but in a delayed fashion. In other words, noun plurals will develop first, and the use of the uncontractible copula and regular past tense will follow. An alternative hypothesis (the “perceptual prominence” hypothesis) is that the pattern of language development in CI users will be strongly affected by the perceptual prominence of the relevant morphological markers. This hypothesis predicts that the uncontractible copula will develop first, followed by noun plurals, and then by regular past tense. A sentence completion task was used to measure the performance of 9 pediatric CI users and compare it to that of several groups of children with normal hearing. The results from the CI users were consistent with the perceptual prominence hypothesis. In particular, the scores for the copula probe were higher than those for the noun plural probe for 8 of the 9 CI users. This result represents a rather striking inversion with respect to the usual development pattern in children with normal hearing and even in children with specific language impairment. If the perceptual prominence hypothesis receives further support in future studies, clinicians who work in language rehabilitation of CI users may choose to target those aspects of grammar that are less acoustically prominent to these children. In addition, and from a theoretical standpoint, these results suggest that although there may well be an innate language acquisition mechanism, patterns of language development can be strongly affected by the acoustic input.

The usual development of the Lebesgue integral starts with a measure that may have been derived from some simpler set function, its associated class of measurable sets, the corresponding set of measurable functions, and operations which ultimately define the integral of any given function of this class, except for certain ones which are unbounded above and below. Here we propose to define a process of integration with respect to a set function more general than a measure. This process allows us to integrate virtually all functions real-valued on our space. The integrals thus obtained are all completely additive on a certain completely additive class of sets. Under rather mild hypotheses, we are able to delineate this class of sets explicitly.
