This paper begins by presenting and strengthening the labial-velar hypothesis with a novel interpretation of the allophonic distributions of labials and velars in Lusoga (Hyman 2017). The labial-velar hypothesis is an Element Theory proposal that labial (Lab) and dorsal (Dors) consonants are marked by same ‘dark’ place feature |U| (akin to Jakobson & Halle’s (1956) grave). According to this hypothesis, the only difference between Lab and Dors members of any class (say stops) is that Lab is the headed manifestation of |U|, while Dors is the headless version of the same element (Backley & Nasukawa 2009). This, hypothesis however, leads to the strange statement that labial-velar segments such as the labial-velar ‘double’-stop (KP), which would appear to be headless and headed at the same time. What follows is an exploration of the term ‘headedness’ in phonology. Building on the positives of previous approaches, and pairing back the assumptions to the first principles of combination (Merge), I come up with a novel theory of headedness and segment-internal structure: Bare Element Geometry (BEG). The labial-velar hypothesis in light of BEG will then be applied to KP. In order to obtain the right representation for labial-velar ‘double’-stops (KP), it is necessary to precisely understand KP’s distribution and behaviour. Especially because I will reveal some previously unappreciated facts about these segments. In opposition to the classical literature (and all previous accounts known to me), I will conclude that KP is composed of two ordered root nodes, each with a separate place feature. This is based on a detailed typological study and phonological interpretation of attested and unattested nasal + KP assimilation patterns, as well as a novel interpretation of some obscure nasalization facts of KP in Guere (Western Kru). This conclusion that KP has two ordered root nodes is what allows BEG’s model of headedness to interpret a feature as simultaneously headed and headless in different parts of a segment. Moreover, it correctly predicts Cahill (1999)’s empirical observation that KP is universally headed by Labial.

One of the main activities in psychometrics is to analyze the internal structure of a test. Multivariate statistical methods, including Exploratory Factor analysis (EFA) and Principal Component Analysis (PCA) are frequently used to do this, but the growth of Network Analysis (NA) places this method as a promising candidate. The results obtained by these methods are of valuable interest, as they not only produce evidence to explore if the test is measuring its intended construct, but also to deal with the substantive theory that motivated the test development. However, these different statistical methods come up with different answers, providing the basis for different analytical and theoretical strategies when one needs to choose a solution. In this study, we took advantage of a large volume of published data (n = 22,331) obtained by the Ages and Stages Questionnaire Social-Emotional (ASQ:SE), and formed a subset of 500 children to present and discuss alternative psychometric solutions to its internal structure, and also to its subjacent theory. The analyses were based on a polychoric matrix, the number of factors to retain followed several well-known rules of thumb, and a wide range of exploratory methods was fitted to the data, including EFA, PCA, and NA. The statistical outcomes were divergent, varying from 1 to 6 domains, allowing a flexible interpretation of the results. We argue that the use of statistical methods in the absence of a well-grounded psychological theory has limited applications, despite its appeal.

A novel theory of the healthcare policy of right-wing governments is presented in this article. It posits that the politics of health care is inherently different from the politics of a social policy related to the labour market. Health care protects against risks that are in the main uncorrelated with the income distribution. This implies that median voters will favour public provision, while high-income voters will not. This generates a unique challenge to right-wing governments that have to balance the interests of the two. The solution is marketization via compensation, where public spending is expanded but where public support of private market solutions is given special priority.


The author, having received a male wombat alive from one of the islands in Bass’s Straits, had an opportunity of observing its habits in a domesticated state, and of examining the peculiarities of its internal formation after death, particularly the mechanism of the bones and muscles of its hind legs, which have not been described either by Geoffroy, in his account of its internal form, or by Cuvier, who has described several parts of its internal structure in his Lecons d’Anatomie Comparée . The stomach of the wombat resembles closely that of the beaver, and differs so much from that of the kanguroo, and other animals of the opossum tribe, that it forms an extraordinary peculiarity. An account of the dissection of a female wombat having been received from the late Mr. Bell, Surgeon to the Colony at New South Wales, Mr. Home has inserted Mr. Bell’s description, with remarks especially on the state of the uterus, which was double, and impregnated on each side; that on the right side was as large as a pullet’s egg. The os tincæ was filled with a thick gelatinous substance. When a longitudinal incision was made into its cavity, its coats were found lined with the same jelly, in the centre of which was an embryo wrapped up in very fine membranes, that appeared to have no connexion by vessels with either the uterus or the gelatinous matter. These facts, says Mr. Home, throw considerable light on the mode of propagation of this very curious tribe of animals. They confirm, in the most satisfactory manner, the observations contained in a former paper on the kanguroo, which required further evidence, as the specimen on which the observations were made had been sent to England preserved in spirits, and the parts had become very indistinct, from being coagulated and long kept.

AbstractThis essay examines the process by which Wang Guowei placed Chinese dramatic history into the modern Chinese literary canon. It explores how Wang formed his ideas on literature, drawing on Western aesthetics to explain, through the notions of leisure and play, the impetus for art creation, and on the Chinese notions of the genesis of literature to explain the psychology of literary creation. In order to establish the literary value of Chinese drama, Wang applied these ideas to the first playwrights of the Yuan dynasty, arguing that theirs was a literature created under the right aesthetic and creative circumstances, and that it embodied the value of "naturalness" which he considered a universal standard for good literature. By producing a scholarly critical history of the origins and nature of Chinese drama, Wang placed drama on a par with other literary genres of past dynasties, thus giving it a renewed status and creating at the same time a new discipline of research. Drama had now become an established literary genre.

Purpose of the study: The main purpose of this study is to explore the suitability of the self-service technology (SST) factor in transportation marketing research. SST is a novel theory that initially was developed for technology devices. Thus, SST is carry on to examine their usefulness on customer satisfaction and loyalty. Methodology: This research paper is conceptually based on a critical review of self-service technology, customer satisfaction and loyalty toward the Grabcar services in East Coast Malaysia. Main Findings: The researchers propose a model where the self-service technology is accounted for from two different dimensions (Functionality and Enjoyment). This study also makes an attempt to relate all these factors in determining the loyalty of the customers. Applications of this study: This study will enable the decision-maker to understand better ways to increase the satisfaction of the customer. Novelty/Originality of this study: This study offers a theoretical framework for applied researchers who are interested in transportation marketing. As SST becomes popular during Industrial Revolution4.0, this is the right time to promote a new model for investigation purposes.

This chapter focuses on the productive role of government in improving the environment for doing business. Improvements in the performance of government are measured as total factor productivity and differences in income across countries can be explained by differences in the quality of their economic institutions. This makes it essential to understand why some countries make the right investments in legal institutions and deploy such legal capacity effectively. A running theme of the chapter is the possibility of a complementarity between the extractive (taxation) and the productive (supporting markets) roles of government. This is at the heart of the empirical observation that market development and state development move hand in hand. But the key insight from this is that we have to understand the incentives of a government to make investments to improve the workings of the economy.

Abstract We propose a planar model heterojunction based on α-borophene nanoribbons and study its electronic transport properties. We respectively consider three types of heterojunctions. Each type consists of two zigzag-edge α-borophene nanoribbons (Z αBNR), one is metallic with unpassivated or passivated edges by a hydrogen atom (1H-Z αBNR) and the other is semiconducting with the edge passivated by two hydrogen atoms (2H-Z αBNR) or a single nitrogen atom (N-Z αBNR). Using the first-principles calculations combined with the nonequilibrium Green’s function, we observe that the rectifying performance depends strongly on the atomic structural details of a junction. Specifically, the rectification ratio of the junction is almost unchanged when its left metallic ribbon changes from ZBNR to 1H-Z αBNR. However, its ratio increases from 120 to 240 when the right semiconducting one varies from 2H-Z αBNR to N-Z αBNR. This rectification effect can be explained microscopically by the matching degree the electronic bands between two parts of a junction. Our findings imply that the borophene-based heterojunctions may have potential applications in rectification nano-devices.

Background. The keratorefractive surgeries (KRS) are one of the most common ocular surgeries. One of the dangerous complications of these surgeries is infectious keratitis (IK), which is the second cause of blindness after cataract surgery. The purpose of this study was to estimate the prevalence of IK after KRS in different parts of the world. Methods. In order to obtain relevant studies, all national and international databases including IranMedex, SID, Magiran, IranDoc, Medlib, ScienceDirect, PubMed, Scopus, Cochrane, Embase, Web of Science, and Google Scholar were searched using standard keywords. Results. IK prevalence after KRS was 0.000496% (0.000145% for the left eye and 0.000149% for the right eye). IK prevalence after KRS in the United States, Europe, and Asia was 0.000667%, 0.000473%, and 0.000045%, respectively, in all of which the common microorganisms were Staphylococci. Meta-regression showed no significant association between IK after KRS and either sample size or publication year of the studies. IK prevalence after KRS in the right eye was more than that in the left one. Also, the probability of IK incidence after LASIK surgery was more than PRK and LASEK. In the evaluation of continents, IK after KRS in the United States was more frequent compared with Europe and Asia. Conclusions. This study provided data as to the overall prevalence of IK following KRS and its variations according to the types of eye, surgery, pathogenic microorganism, and geographical location.


The author remarks, that Mr. Ware’s observations with regard to short-sightedness, being in general merely the consequence of habit acquired at an early age, is conformable with his own experience in general, and that he himself is a particular instance of natural long-sightedness gradually converted into confirmed short sight. He very well remembers first learning to read, at the common age of four or five years, and that at that time he could see the usual inscriptions across a wide church; but that at the age of nine or ten years he could no longer distinguish the same letters at the same distance, without the assistance of a watch-glass, which has the effect of one slightly concave. In a few years more the same glass was not sufficiently powerful; but yet his degree of short-sightedness was so inconsiderable, that he yielded to the dissuasion of his friends from using the common concave glasses till he was upwards of thirty years of age, when No. 2 was barely sufficient; and he very shortly had recourse to No. 3. In the course of a few years an increase of the defect rendered it necessary for him to employ glasses still deeper, and his sight soon required No. 5, where it has remained stationary to the present time. From the progress which Sir Charles Blagden has observed in his own short-sightedness, he is of opinion that it would have been accelerated by an earlier use of concave glasses, and might have been retarded, or perhaps prevented altogether, by attention to read and write with his book or paper as far distant as might be from his eyes. In this communication he takes the same opportunity of adding an experiment made many years since on the subject of vision, with a view to decide how far the similarity of the images received by the two eyes contribute to the impression made on the mind, that they arise from only one object. In the house where he then resided, was a marble surface ornamented with fluting, in alternate ridges and concavities. When his eyes were directed to these, at the distance of nine inches, they could be seen with perfect distinctness. When the optic axes were directed to a point at some distance behind, the ridges seen by one eye became confounded with the impression of concavities made upon the other, and occasioned the uneasy sensation usual in squinting. But when the eyes were directed to a point still more distant, the impression of one ridge on the right eye corresponded with that made with an adjacent ridge upon the left eye, so that the fluting then appeared distinct and single as at first, but the object appeared at double its real distance, and apparently magnified in that proportion. Though the different parts of the fluting were of the same form, their colours were not exactly alike, and this occasioned some degree of confusion when attention was paid to this degree of dissimilarity.
