The doctrine that the content of the conclusion of a deductively valid argument is included in the content of ITS premises, taken jointly, is a familiar one. It has important consequences for the question of what value valid arguments possess, since it indicates the poverty of three traditional answers: that arguments may and should be used as instruments of persuasion, that they may and should be used as instruments of justification; and that they may and should be used to advance knowledge. The truth is, however, that in each of these cases the argument has only a managerial role and, if there is any work done, it is the premises that do it. It will be maintained that this point has little force against the critical rationalist answer, which I shall defend, that the principal purpose of deductive reasoning from an assemblage of premises is the exploration of their content, facilitating their criticism and rejection. That said, the main aim of the present paper is not to promote critical rationalism but to consider some published objections to the doctrine that a statement asserts every statement that is validly deducible from it. The alleged counterexamples to be considered fall roughly into two groups: statements that emerge with time from a rich mathematical or empirical theory, but were originally unformulated and are deducible from the theory only in a non-trivial way (Frederick 2011, 2014; Williamson 2012); and statements, notably disjunctions, that are easily formulated and are deducible from a theory in a trivial way (Schurz & Weingartner 1987; Mura 1990, 2008; Gemes 1994; Yablo 2014). Each of these counterexamples will be evaluated and dismissed.

After offering an overview of some of the main themes of Popper’s political thought, the paper argues that his account faces two problems relating to institutions. The first is that while Popper stresses the ‘rational unity of mankind’, and the potential for any of us to furnish criticisms of public policy, it is not clear what institutional means currently exist for this to enable this to take place. Second, Popper has stressed the conjectural character of even our best theories. However, at any point, some theories will have fared better in the face of criticism than others, and they may give us important information about constraints on our actions. At the same time, as ordinary citizens we may not be in a good position to understand the theories in question, let alone appraise the state of the specialised discussion of them. There is, it is suggested, a case for thinking of ways to institutionally entrench such fallible theories, especially in the current setting in which social media play an important role

The paper offers a distinctive reading of Popper’s work, suggesting that his Logic of Scientific Discovery (LScD) might be re-interpreted in the light of his Open Society. Indeed, Popper can be interpreted as criticising certain aspects of his first book, and as a result improving upon them, in his second. It suggests translating what Popper says about ‘conventions’ into his later vocabulary of ‘social institutions’. Looking back, I believe that Popper never intended the language of conventions and decisions to be read individualistically. I remain unsure whether Popper was himself quite as clear about this as he could have been.  My reading makes Popper a pioneer in the sociology of science. Scientific institutions are arenas of political power; but Popper did not discuss the structure and inter-relations of the social institutions of science, or offer a politics of science in the context of his methodology. What is missing from the skeletal sociology of LScD is the politics. We could put it in Popperian terms this way: scientific institutions are both open and closed. They are closed, firmly, to the inexpert, to the non-members; supposedly they are open to the qualified, provided the prerogatives of seniority and leadership are acknowledged. Despite these shortcomings, Popper’s critical and rational approach and his insistence on openness and intellectual honesty are still important today.

ITS system architecture includes creating coordination among smart transportation systems and equipment in a framework and in an integrated manner, in such a way that these systems work as a united whole in order to reduce traffic problems. In this paper, a new method to achieve a logical model for ITS architecture in Tehran metropolis is presented for the first time. Based on this method, a model for Tehran’s ITS logical architecture is developed. For this purpose, the architectures of leading countries in this regard such as US, European countries, Japan, and Canada were studied first. Since the United States is the pioneer country in ITS architecture and other countries have developed their ITS architectures based on the experiences of the United States, ITS architecture of US is used as the standard model in this paper. First, the draft of ITS logical architecture for Tehran metropolis was prepared based on the needs and the available sources. Then, this draft was revised using the opinions of twenty ITS experts who filled out two questionnaires. In these questionnaires, the experts were asked to identify the relationships among different processes and the relationships between these processes and external factors. In this way, the ITS logical architecture of Tehran metropolis was shown by plotting DFD diagram.

Water Water deficit especially after heading is one of the most effective factors of wheat yield loss in Iran and across the world and identifying the physiological traITS related to plant resilience is of great importance in screening for tolerant varieties. The objective of this study was to evaluate the variation in stem reserves accumulation capacity and ITS relationship with remobilization in some wheat cultivars. 22 wheat cultivars were cultivated in a split plot design with three replications, full irrigation and 40% of field capacity being main plots. The amount of accumulation and remobilization was estimated by measuring internodes weight and stem soluble carbohydrates content (WSC). Significant genotypic variation among cultivars was observed under both normal and drought conditions. Maximum accumulation was found in lower internodes followed by peduncle and penultimate using dry weight measurement method. In WSC measurement method, however, maximum accumulation was observed in penultimate followed by lower internodes and peduncle. Cultivars ranking based on accumulation was also different in two methods. Drought stress caused decline in internodes weight, WSC and yield and remobilization efficiency. The specific stem weight had the highest correlation with remobilization. Significant correlation was found between grain yield and remobilization, specific stem weight and WSC.

One may say that The Open Society and ITS Enemies (OS) offered in 1945 the first complete elaboration of the general approach proposed by Karl Popper, namely his ‘critical rationalism’, a bold generalization of the fallibilist falsificationism in the domain of the empirical sciences masterly proposed in Logik der Forschung (1934). The political content of The OS has been critically discussed. Nevertheless, not all people insist on the equally important moral dimension of the book, giving it ITS unity, I submit. Without morality, no critical discussion, no reason, no open society, let us say in a nutshell. I would argue that according to Popper, a strictly Christian morality of love would not be the appropriate emotional companion of critical rationalism, but that the less demanding moral emotion of sympathy or compassion is perhaps necessary to give it ITS force against violence. I give some support to this line of argument. In my view, Popper proposed a somewhat unarticulated critical rationalist ‘emotivism’ of sorts. The emotion of compassion is necessary for triggering our moral decisions and values, which are the ultimate basis of the choice for a reason against violence.

The importance of female heads of households in providing the basic needs of household members on the one hand and the limitations they face in most socio-economic fields have made it necessary to pay attention to the issues of female heads of households in most societies including our country. The purpose of this study is to use the systematic review method to review and evaluate the policy proposals that have been proposed in Iran for women heads of households. A total of 296 articles and 5 reports were identified. In the review and eligibility phase, the total number of selected texts was considered to be 79 texts, of which 62 studies used the quantitative method and 17 studies used the qualitative method. Based on the studies that proposed policy proposals, the characteristics of female heads of the household, the axes of vulnerability, the evaluation of policies and proposals were determined. The findings showed that more policy proposals were made based on the characteristics of low literacy, being unemployed, and being middle-aged. Based on the axes of vulnerability, women heads of households are more vulnerable psychologically and socially than they are materially vulnerable in many cases. The evaluation of policies for women heads of households showed that the most interventions for the empowerment of women heads of households were focused on the economic field and were mainly pursued in the form of financial payments and did not pay enough attention to other aspects of women's empowerment, while the empowerment of women heads of households was successful when It is expected to simultaneously pay attention to their mental health and improve their social and economic status.

Absidia is a genus in the family Absidiaceae in the order Mucorales some species of which are causative agents of mucormycosis in humans and animals. To study phylogenetics and population biology of the genus and ITS species, some some soil samples were collected from agricultural areas of Mazandaran. Following isolation and purification of isolate an Rose-bengal containing medium, 20 isolates of Absidia were obtained. DNA was extracted from using a CTAB method and subjected to PCR using the primers ITS4 and ITS5 and the amplified fragments were sequenced. The sequences were analyzed by Chromas Pro and MEGA5 softwares and compared with those deposited in GenBnak. Dendrograms derived from the similarity of nucleotide sequences separated Absidia repens isolates, which formed a distinct calde, from the rest of the species.
