Making Competitive Cities in the Light of the Meta-SWOT Tool: A Case Study of Tehran,Iran

ABSTRACT

While there is a growing body of scholarship on regional competitiveness, little attention has been paid to the planning methods that can pursue this objective. Public planners are mainly relying on conventional methods that have come under increasing criticism. This study aims to introduce Meta-SWOT as a novel planning tool in urban and regional studies. Meta-SWOT provides competitive and realistic strategies for planners. It systematically tries to present strategies rooted in internal resources and capabilities while acknowledging the challenges posed by the external environment. Nevertheless, it has several limitations that should be considered when applying to urban and regional planning.     

How a Divorcee’s Sexual Life Is Socially Constructed and Understood in the Iranian Culture

Sexual well-being is an important factor in postdivorce adjustment and presents various challenges for divorced women in Iran. With an alarming number of marriages ending in divorce in Iran, the postdivorce sexuality adjustment process has become a major concern. Meanings attached to the sexuality of a divorcee necessitate different adjustment and coping strategies among women. How these meanings are generated, negotiated, and modified in Iranian contexts has yet to be explored. We used a grounded theory approach to analyze the extensive, rich data obtained through sustained interaction with the informants as well as through in-depth individual interviews and focus group discussions. “Sociosexual problems” was found to be one of the main domains in our study. Participants experienced a negative impact from divorce on their sexual lives, including sexual interactions. Social isolation and social exclusion resulted from the avoidance of stereotypic interactions and were often a consequence of difficulties with concealment of sexual needs due to stigma. Women discussed a range of negative experiences arising in response to their sexual needs in postdivorce life. The analysis revealed the complexities of gendered postdivorce sexual trajectories. Based on the findings, articulating a sexual health model specific for divorced women seems important.     

The Role of Metacognition in the Development of EFL Learners’ Listening Skill

This study investigated the impact of metacognitive instruction on the listening skill, and metacognitive knowledge of a group of male students (N = 30) who were learning English as a Foreign Language (EFL) in Iran. The study participants spoke Persian as a first language and were high-intermediate EFL learners. The participants received a guided lesson plan in metacognition (planning, monitoring, and evaluation) through a pedagogical cycle approach over a semester (eight weeks). International English Language Testing System listening tests (practice) were used to track the participants’ listening performance. Participants also completed a Metacognitive Awareness Listening Questionnaire, which examined their use of metacognitive awareness when engaged in listening tasks. Results indicated that the students improved their listening skill after being taught about metacognition; however, no significant use of metacognitive awareness was reported. This study concludes with a discussion of some potential implications, and provides scope for future research.     

A simplified algebraic method for system of linear inequalities with LP applications

In this pedagogical note we present an improved method to solve and analyze linear programming (LP) problems. The method depends on solving a system of equations and is free of any slack, surplus or artificial variables. The proposed method eliminates the need to manipulate linear inequalities to introduce additional variables and works only within the original decision variables space. We present applications of the method to handle linear optimization with varying objective function. The proposed method is easy to implement and enhances understanding of the simplex method and LP solvers transparent. We believe it is a useful alternative approach to present LP in the class room during the first few hours of introducing the subject.     

Bounding the total domination subdivision number of a graph in terms of its order

The total domination subdivision number \(\mathrm{sd}_{\gamma _{t}}(G)\) of a graph G is the minimum number of edges that must be subdivided (each edge in G can be subdivided at most once) in order to increase the total domination number. In this paper we prove that \(\mathrm{sd}_{\gamma_{t}}(G)\leq \lfloor\frac{2n}{3}\rfloor\) for any simple connected graph G of order n≥3 other than K ₄. We also determine all simple connected graphs G with \(\mathrm{sd}_{\gamma_{t}}(G)=\lfloor\frac{2n}{3}\rfloor\).
