This paper investigates how to change the disassortativity of the whole network by connecting nodes of different types in two communities. A model connecting two multi-center networks is studied to see if analytical results are achievable. There are three main methods to connect two multi-center subnetworks depending on whether the connecting nodes are centers: (1) connect the centers of one sub-network to noncenter nodes of the other sub-network, (2) connect the centers of the two sub-networks together, and (3) connect non-center nodes of the two sub-networks. The results show that the disassortative property of a single multicenter network can be maintained in scenarios (1) and (2) above, but the disassortativity is changed in (3). In conclusion, either assortativity or disassortativity is achievable by connecting nodes with different degree properties in an ideal network constructed from two communities with similar network topology.

Abstract Physicians and nurses stand with their back towards the C-arm fluoroscope when using the computer, taking things out of closets and preparing drugs for injection or instruments for intervention. This study was conducted to investigate the relationship between the type of lead apron and radiation exposure to the backs of physicians and nurses while using C-arm fluoroscopy. We compared radiation exposure to the back in the three groups: no lead apron (group C), front coverage type (group F) and wrap-around type (group W). The other wrap-around type apron was put on the bed instead of on a patient. We ran C-arm fluoroscopy 40 times for each measurement. We collected the air kerma (AK), exposure time (ET) and effective dose (ED) of the bedside table, upper part and lower part of apron. We measured these variables 30 times for each location. In group F, ED of the upper part was the highest (p < 0.001). ED of the lower part in group C and F was higher than that in group W (p = 0.012). The radiation exposure with a front coverage type apron is higher than that of the wrap-around type and even no apron at the neck or thyroid. For reducing radiation exposure to the back of physician or nurse, the wrap-around type apron is recommended. This type of apron can reduce radiation to the back when the physician turns away from the patient or C-arm fluoroscopy.

Depression is one of the most commonly observed medical conditions. Studies about the depression and life satisfaction is increasing day by day. Untreated depression may lead to unexpected earlier deaths and has negative impacts on the patient’s general health conditions. On the other hand with the proper treatment, life quality could be enhanced. Moreover life satisfaction level is also seen as an important factor which is related with life quality and which is usually coordinated together with the depression. There are different types and explanations of depression. In this study, we tried to explain the prevalence, diagnosis criterias, risk factors, etiology and description of depression. In addition to this, relationship between depression and life satisfaction is tried to be explained. Purpose of this review study is to explain depression, it’s risk factors and the importance of life satisfaction.

This paper presents data and observations concerning Chamaedaphne calyculata (L.) Moench. (Ericaceae). The branching pattern, the longevity of different types of leaves, and features of flowering are shown to be correlated. The relationship between this complex of features and the habitat is studied, and a few speculations are advanced to explain the physiological basis for the behavior of Chamaedaphne. This study is essentially autecological, and it is hoped that it may constitute a link between the study of soil conditions and the response of plant hormones on the one hand, and phytosociological work in peat bogs on the other hand.

Purpose – The purpose of this paper is to describe how discovery and creation opportunities transition from one to the other and thereby clarify the relationship between opportunity types. This theoretical work will offer insight for studying opportunities and clarify the different practical implications of different opportunity types. Design/methodology/approach – To further the understanding of opportunity types, the paper employs Dubin’s (1978) theory building methodology focussing specifically on the concepts of system states. Approaching opportunity types as system states clarifies the relationship between discovery and creation opportunities. Findings – This research argues that opportunities transition from creation opportunities to discovery opportunities. Furthermore, understanding the opportunity state can clarify the practical implications for entrepreneurs. In particular, entrepreneurs in discovery states employ different processes regarding human resources, strategy, financing, planning, leadership, and potential competitive advantage than entrepreneurs pursuing creation states. Originality/value – This paper offers value to researchers by clarifying the differences between opportunity types. To date, there has been little to no investigation into how opportunity types change from one type to another. This research offers to clarify the debate about the existence of different opportunity types and move the discussion forward theoretically. Additionally, this manuscript offers practical insights for entrepreneurs pursuing different types of opportunities.

The relationship between the doctor and the patient is a particular type of human relation. On one hand, the word «patient» states that a person is at a disadvantage, because of his/her illness, and therefore is automatically at a disadvantageous position compared to the doctor. On the other hand, the patient has the opportunity to inform him/herself from online sources, to communicate with other patients, to participate as equal and to choose consciously his/her treatment plan.There are many different types of patients depending on their personality and interaction with their doctor. These types constituted a research field in the 80’s which lead to the analysis of patients’ psychology. After an historical flashback, patients are put in categories according to their reaction to their illness. In addition, the verbal way of approaching patients by their doctor, the patients’ expectations and their encouragement by professionals to participate more actively concerning their health care is underlined. As a result, this is the beginning of a new era, where the patient has requirements concerning both the medical and the human aspect of the doctor-patient relationship.

The aim of the current study was to investigate students' mind wandering while reading different types of textual narrations (macroscopic and submicroscopic) in chemistry. Another goal was to determine the relationship between mind wandering and students' reading comprehension. The participants were 65 female ninth grade students in Oman. Using a computer screen, participants were required to read about sodium chloride. A probe-catch procedure was used to measure students' mind wandering. Half of the slides presented textual narrations at the macroscopic level and the other half presented narrations at the submicroscopic level. We gave the students a paper and pencil reading comprehension test at the conclusion of the reading task. The findings indicated that participants' mind wandering while reading submicroscopic textual narrations was significantly higher when compared to reading macroscopic textual narrations. Also, there was a significant negative relationship between mind wandering and reading comprehension for both macroscopic and submicroscopic textual narrations. Implications and future research are discussed.

As the pandemic limited our lives, people engaged in their favorite activities; either in alternative ways or while disregarding the restrictions. These major activities and our engagement in these activities of life are considered to have a significant impact on our mental health. Thus, this study aimed to examine the relationship between two types of passion (harmonious passion and obsessive passion), fear of COVID-19 (emotional fear responses, symptomatic expressions of fear), and mental distress. To this end, 322 Japanese participants completed an online questionnaire. The results showed that harmonious passion (HP) was positively related to emotional fear responses and negatively to mental distress. On the other hand, obsessive passion (OP) was positively associated with symptomatic expressions of fear and negatively with mental distress. Symptomatic expressions of fear have a stronger positive relationship with mental distress than emotional fear reactions. This study evidenced that HP is a protective factor against pandemics as it improves mental health while appropriately recognizing fear of COVID-19. Focusing on different types of passion may prove effective in improving mental health amidst the pandemic.

This chapter examines property rights in land and personal rights that may allow a party to make a particular use of land. It first considers the distinction between personal rights and property rights before addressing the content question: whether the type of right claimed by a party counts as a property right. To answer that question, a distinction is made between different types of property right. The most important distinction is between legal property rights, on the one hand, and equitable property rights, on the other. The chapter also discusses licences to use land and contrasts their operation and effect with those of property rights in land. It highlights the nature of licences and the controversy over contractual and estoppel licences and concludes with an analysis of the relationship between the law of leases and of licence.

Conversion is a key type of word-formation process in English, but the precise nature of the relation between base and derivative in conversion is rarely discussed, even if conversion is considered as a dynamic process. When it is considered explicitly, the relation has been described in terms of paradigmatic relations between lexemes, specifically homonymy or polysemy. This is usually without any specification of how converted words accommodate the conditions set by the definition of each of these relations, and as a special type of one or the other, because conversion-related words violate some of those conditions. This article is intended as a systematic review of the literature that discusses the relation between conversion-related words in English. We show that a wide range of proposals have been made to describe the relation: homonymy, heterosemy, homomorphy, zero-derivation (as a relation), polysemy, lexical extension, synsemy, hyponymy and paronymy. We review the extent to which each of these terms fits the relationship in major types of conversion, and argue that, if a relationship is to be described between conversion-related pairs, then Cruse's (1986) separation of semantic relations of a paradigmatic type from paronymic relations is of special relevance here. We propose that, regardless of the direction and type of meaning, paronymy applies across the various specific semantic patterns that conversion may involve. We emphasize, however, the possibility of several relations according to the type of conversion, i.e. different types of conversion may need description in terms of a different relation.
