Nitrite Toxicity

Nitrite is an intermediate in the oxidation of ammonium to nitrate. An elevated ambient nitrite concentration is a potential problem for freshwater fish since nitrite is actively taken up across the gills in competition with chloride. Nitrite is a well-known toxicant for fish as well as a disrupter of multiple physiological functions including ion regulatory, respiratory, cardiovascular, endocrine and excretory processes. One critical consequence of nitrite accumulation is the oxidation of haemoglobin to methaemoglobin, compromising blood oxygen transport. Nitrite toxicity to fish varies considerably and depends on a large number of external and internal factors. Among the most important ones are water quality (e.g. pH, temperature, cation, anion and oxygen concentration), length of exposure, fish species, fish size and age, and individual fish susceptibility. Chloride concentration in water is considered one of the most important factors influencing nitrite toxicity to fish. The importance of individual factors is assessed and re-evaluated continuously.

This literature review summarizes research on member influence in cooperatives conducted in Scandinavia and some of the research conducted in West Germany. The review divides the contents of member influence into three components; individual factors, the cooperative organization’s internal factors and the organization’s external factors. As individual factors, participation, representation and representativeness are considered. Conflicts in cooperative organizations, the effect of the growth of the organization and the rules of decision making are discussed as organizations internal factors. The major interest groups in addition to members (the market, personnel and the society) are presented as external factors. The external factors are increasingly challenging the nature of cooperatives as member interest organizations.

Causal Judgments

Abstract Given the prominence of studies aimed at determining the factors influencing causal judgments, this study attempts to introduce the newly-developed concept of emotioncy as one of the guiding factors pushing attribution judgments toward a certain spectrum. To this end, two scales of attribution and emotioncy were designed using ten hypothetical situations. A total number of 309 participants filled out the scales. The construct validity of the scales was substantiated through confirmatory factor analysis (CFA). Afterwards, structural equation modeling (SEM) was utilized to examine the possible relationships among the sub-constructs of attribution and emotioncy scales. The results indicated that as the participants’ emotioncy level increases, it becomes more likely for them to attribute probable causes to external factors. Moreover, it was revealed that while the involved individuals attribute causes to external factors, the exvolved ones attribute them to internal factors. In the end, implications of the findings were discussed in the realm of judgment and decision making.

Abstract Several studies in the area of third language acquisition (L3A) have considered various factors influencing this process, but the effect of language dominance has not been thoroughly examined. The main goal of this study is to investigate whether the acquisition of relative clauses (RCs) in L3 English is influenced by language internal factors, such as the syntactic features of the target language, or by external factors in the form of cross-linguistic influence (CLI). A total of 90 participants (40 Spanish-dominant, 40 Basque-dominant, 10 L1 Spanish-L2 English) and 10 native speakers of English completed a production and a comprehension task. Findings show that the L3 learners’ production of RCs seems to be driven by language internal factors, whereas their comprehension appears to be influenced by their previously acquired languages, mainly by Spanish. It is concluded that neither language dominance nor other traditionally considered factors play a determinant role in the acquisition of RCs in L3 English by these participants.

Conservation of our global natural resources is one of the most pressing concerns facing our international society. One of these crucial resources is water. The current study sought to understand how individual factors such as experience with water scarcity, message framing, and ideology can impact perceptions, attitudes, and behaviors related to water conservation. Through the utilization of an online experiment, the current findings suggest that higher levels of experience with water scarcity predict more concern, more positive credibility perceptions of water conservation messages, and a higher likelihood of conserving water in the future. Message framing, specifically gain frames, predicted more concern and more positive perceptions of message credibility, and ideology only predicted perceptions of message credibility. Implications for global communities, resource managers, and policy decision-makers are discussed.

<p class="apa">This study was undertaken to explore the critical factors influencing the self-concept of community college graduates in the development of their careers. Individuals with a positive self-concept are often associated with a good career choices and a well-panned career development path. Hence community college students should be girded with a positive self-concept to ensure success in their future careers. This qualitative research using multiple case study methods involved 15 community college graduates who have been relatively successful in their respective careers and were able to generate high incomes. Further data obtained were analysed using NVivo 8.0 to determine the relevant themes that emerged. The study observed the presence of five critical internal factors influencing self-concept: congruence, boldness in facing a challenge, vision, skills and experience.</p>
