This paper studies two dual notions in module theory—namely, radicals and socles—from the standpoint of reverse mathematics. We first consider radicals of Z-modules, where the radical of a Z-module M is defined as the intersection of pM={px:x∈M} with p taken from all primes. It shows that ACA0 is equivalent to the existence of radicals of Z-modules over RCA0. We then study socles of modules over commutative rings with identity. The socle of an R-module M is the largest semisimple submodule of (...) M. We show that the existence of socles of modules over a commutative ring with identity is equivalent to ACA0 over RCA0. Vector spaces are semisimple modules over fields. In general, semisimple modules possess nice properties of vector spaces. Lastly, we study characterizations of semisimple modules over commutative rings using techniques of reverse mathematics. (shrink)

In order to address the influence of unethical leader behaviors in the form of abusive supervision on subordinates’ retaliatory responses, we meta-analytically examined the impact of abusive supervision on subordinate deviance, inclusive of the role of justice and power distance. Specifically, we investigated the mediating role of supervisory- and organizationally focused justice and the moderating role of power distance as one model explaining why and when abusive supervision is related to subordinate deviance toward supervisors and organizations. With 79 independent sample (...) studies, we found that abusive supervision was more strongly related to supervisory-focused justice, compared to organizationally focused justice perceptions, and both types of justice perceptions were related to target-similar deviance. Finally, our results showed that the negative implications of abusive supervision were stronger in lower power distance cultures compared to higher power distance cultures. (shrink)

The regional principle of socioeconomic and political development has always served as the basis of the existence of developed states. The rights of regions have been severely curtailed only in countries with a totalitarian system of government.

The interaction between philosophy and political parties is one of the most lively questions in the discipline of the history of philosophy and in the battle of ideas today. It affects both specialists in philosophy and representatives of other professions, particularly in the broad realm of creative intellectuals. It excites people of different generations living under different social systems and belonging to different and often opposed classes.

In China, there have been numerous reports that doctors or other health care workers have been attacked by patients or members of patient’s families. From 2000 to 2003, there were 502 reports of violence against health care workers in the city of Beijing, in which 90 health care workers were wounded or disabled. From January 1991 to July 2001, in Hubei Province, 568 attacks on health care facilities and workers were reported, and some health care workers were even killed. In (...) Jiangsu Province, from 2000 to 2002, violent events against health care facilities and workers increased by 35% every year, with an average of 177 such events occurring each year. Those acts of violence have been attributed, in part, to the inadequacy of the legal system for handling medical disputes that was in effect prior to 2002. (shrink)

Lead (Pb) contamination of the environment is an important human health problem. Children are vulnerable to Pb toxicity; it causes damage to the central nervous system and, in some extreme cases, can cause death. Lead is widespread, especially in the urban environment, and is present in the atmosphere, soil, water and food. Pb tends to accumulate in surface soil because of its low solubility, mobility, and relative freedom from microbial degradation of this element in the soil. Lead is present in (...) soil as a result to weathering and other pedogenic processes acting on the soil parent material; or from pollution arising caused by the anthropogenic activities; such as mining, smelting and waste disposal; or through the adoption of the unsafe and unethical agricultural practices such as using of sewage sludge, and waste water in production of vegetable crops or cultivation of vegetables near highways and industry regions. Lead concentrations are generally higher in the leafy vegetables than the other vegetables. Factors affecting lead uptake included its concentration in the soil, soil pH, soil type, organic matter content, plant species, and unsafe agriculture practices. Generally, as Pb concentration increased; dry matter yields of roots, stems and leaves as well as total yield decreased. The mechanism of growth inhibition by lead involve: a decrease in number of dividing cells, a reduction on chlorophyll synthesis, induced water stress to plants, and decreased NO 3 - uptake, reduced nitrate and nitrite reductase activity, a direct effect of lead on protein synthesis, a decrease on the uptake and concentration of nutrients in plants. The strategies to minimize Pb hazard can be represented in: (a) Phytoremediation, through natural plants are able to bio-accumulate Pb in their above–ground parts, which are then harvested for removal such as, using Indian Mustard (Brassica juncea), Ragweed (Ambrosia artemisiifolia), Hemp Dogbane (Apocynum cannabium), or Poplar trees, which sequester lead in its biomass. (b) Good and ethical agricultural practices such as cultivation of vegetables crops as far from busy streets or highways and industry regions as well as nonuse of sewage sludge and waste water in cultivated soils. (c) Increasing the absorptive capacity of the soil by adding organic matter and humic acid. (d) Growing vegetable crops and cultivars with a low potential to accumulate lead, especially in soils exposed to atmospheric pollution. (e) Washing of leafy vegetables by water containing 1 % vinegar or peeling roots, tubers, and some fruits of vegetables before consumption may be an important factor in reducing the lead concentration.

While there had still been an increasing flow of foreign direct investment (FDI) into China during the 2002 downturn in FDI globally, such investments have historically been only sporadically successful. Much writing has detailed and discussed problems associated with China FDI but several costs remain dangerously overlooked. One such cost is that of micro-monitoring plants for work conditions and employee treatment in violation of local Chinese laws and possible home country ethics. Further, a more personal cost is presented – the (...) personal cost associated with maintaining an investment in a facility that violates standards of ethical employee treatment. Background information related to these issues is presented, along with a general overview of FDI in China. (shrink)

OBJECTIVE: To report and analyse the pattern of end-of-life decision making for terminal Chinese cancer patients. DESIGN: Retrospective descriptive study. SETTING: A cancer clinical trials unit in a large teaching hospital. PATIENTS: From April 1992 to August 1997, 177 consecutive deaths of cancer clinical trial patients were studied. MAIN MEASUREMENT: Basic demographic data, patient status at the time of signing a DNR consent, or at the moment of returning home to die are documented, and circumstances surrounding these events evaluated. RESULTS: (...) DNR orders were written for 64.4% of patients. Patients in pain (odds ratio 0.45, 95% CI 0.22-0.89), especially if requiring opioid analgesia (odds ratio 0.40, 95% CI 0.21-0.77), were factors associated with a higher probability of such an order. Thirty-five patients were taken home to die, a more likely occurrence if the patient was over 75 years (odds ratio 0.12, 95% CI 0.04-0.34), had children (odds ratio 0.14, 95% CI 0.02-0.79), had Taiwanese as a first language (odds ratio 6.74, 95% CI 3.04-14.93), or was unable to intake orally (odds ratio 2.73, 95% CI 1.26-5.92). CPR was performed in 30 patients, none survived to discharge. CONCLUSIONS: DNR orders are instituted in a large proportion of dying Chinese cancer patients in a cancer centre, however, the order is seldom signed by the patient personally. This study also illustrates that as many as 20% of dying patients are taken home to die, in accordance with local custom. (shrink)

The problem considered in the article that follows has a long and complicated history. The many different solutions proposed reflect the process of development, deepening, and broadening of knowledge as a whole. They correspond to particular levels of knowledge, determining the character of thought both of the times and of particular individuals. Specifically, it is the understanding of the essence of contradiction that governs the entire theoretical exposition that follows, its substance and approximation to truth. Here we shall consider for (...) analysis only one aspect of this fundamental theme — dialectical contradiction in the evolution of knowledge. Thus, for the most part the discussion will be of the laws of thought; only when necessary will we turn to analysis of contradictions in the objective world. It is quite understandable that the process of thought should occur according to the same, more general laws that are operative in the objective world; nevertheless, the manifestation of these laws has its own special features. Therefore, the questions posed by philosophers of antiquity concerning the degree to which reality itself corresponds to the understanding thereof in terms of the exactness, comprehensiveness, and depth of reflection of the objective world by a subject have not lost their timeliness. Such questions include those associated with the phenomenon of contradiction. For example, is contradiction in thought adequate to the contradictions among things ? How does contradiction in thought take shape, and what are its forms and structures? Is the relationship between opposites always a contradiction? Is it possible to solve antinomies, and so forth? An extensive literature has been published on these subjects. There is hardly a philosopher who can avoid them and not express his attitude toward them. As it is impossible, within the confines of an article, to adduce a full list of published works on contradictions, the authors, with an eye to what has been achieved in this sphere, also regard it as undesirable to analyze the diversity of points of view, and will confine themselves to presenting their own understanding of the problem under consideration.

Tuberculosis (TB) is a potentially fatal infectious disease that, in Aotearoa New Zealand (NZ), inequitably affects Asian, Pacific, Middle Eastern, Latin American, and African (MELAA), and Māori people. Medical research involving genome sequencing of TB samples enables more nuanced understanding of disease strains and their transmission. This could inform highly specific health interventions. However, the collection and management of TB isolate samples for research are currently informed by monocultural biomedical models often lacking key ethical considerations. Drawing on a qualitative kaupapa (...) Māori–consistent study, this paper reports on preliminary discussions with groups of Māori, Pacific, and Afghan people in NZ, whose communities have been harmed by TB and TB stigma. Participants’ discussions highlight key concerns and meanings that ought to inform the development of guidelines and a more robust consultative process for the governance of how TB isolate samples are collected and used both retrospectively and in future research. We argue for ethical processes to be culturally nuanced and community-generated, flexible and meaningful, and situated in relation to the physical and symbolic effects of TB. We discuss the significance of Indigenous data sovereignty, rights, and kāwanatanga (governorship) in shaping a multicultural data sovereignty model. (shrink)

Research investigating the underlying mechanisms and boundary conditions under which leader humility influences employee voice remains underdeveloped. Drawing from approach–inhibition theory of power and leader humility literature, we developed a moderated-mediation model in which personal sense of power (i.e., employees’ ability to influence other individuals such as their leader) was theorized as a unique mechanism underlining why employees feel motivated to speak up under the supervision of humble leaders. Additionally, the cultural value of power distance was proposed to be a (...) relevant boundary condition to influence such relationship. We tested the model using time-lagged supervisor–subordinate matched data. Results of mixed models analyses provided support for our hypotheses confirming that employees’ personal sense of power mediates the relationship between leader humility and employee voice, and such relationship was found to be stronger when employees’ power distance was lower rather than higher.

© 2019 The Author. Background: The phenomenon of being 'with woman' is fundamental to midwifery as it underpins its philosophy, relationships and practices. There is an identified gap in knowledge around the 'with woman' phenomenon from the perspective of midwives providing care in a variety of contexts. As such, the aim of this study was to explore the experiences of being 'with woman' during labour and birth from the perspective of midwives' working in a model where care is provided by (...) a known midwife. Methods: A descriptive phenomenological design was employed with ten midwives working in a 'known midwife' model who described their experiences of being 'with woman' during labour and birth. The method was informed by Husserlian philosophy which seeks to explore the same phenomenon through rich descriptions by individuals revealing commonalities of the experience. Results: Five themes emerged 1) Building relationships; 2) Woman centred care; 3) Impact on the midwife; 4) Impact on the woman; and 5) Challenges in the Known Midwife model. Midwives emphasised the importance of trusting relationships while being 'with woman', confirming that this relationship extends beyond the woman - midwife relationship to include the woman's support people and family. Being 'with woman' during labour and birth in the context of the relationship facilitates woman-centred care. Being 'with woman' influences midwives, and, it is noted, the women that midwives are working with. Finally, challenges that impact being 'with woman' in the known midwife model are shared by midwives. Conclusions: Findings offer valuable insight into midwives' experiences of being 'with woman' in the context of models that provide care by a known midwife. In this model, the trusting relationship is the conduit for being 'with woman' which influences the midwife, the profession of midwifery, as well as women and their families. Descriptions of challenges to being 'with woman' provide opportunities for professional development and service review. Rich descriptions from the unique voice of midwives, provided insight into the applied practices of being 'with woman' in a known midwife model which adds important knowledge concerning a phenomenon so deeply embedded in the philosophy and practices of the profession of midwifery.
