The Pediococcus strains belong to the group of lactic acid bacteria (LAB). This study aims to isolate and identify the Pediococcus spp. from mother’s milk, and investigate their tolerance to low pH and bile salts, antibacterial activity, attachment to HT-29 cells and effect on cholesterol-lowering and digestive enzymes in mice.

Pediococcus species were isolated from mother’s milk, then tested for tolerance to acid and bile salts, their antibacterial effect and attachment to HT-29 cell line. In mice experiment, the levels of triglyceride (TG), total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C) and digestive enzymes such as amylase and lipase in serum of mice were measured after administration of 10⁸ CFU/mL bacterial suspension.

A total of 24 Pediococcus spp. including 16 isolates of Pediococcus pentosaceus and 8 isolates of Pediococcus acidilactici were isolated. Fifteen isolates (62.5%) were able to survive in low pH and bile salt concentration. Ten isolates (41.6%) exhibited the most powerful inhibitory effects against both Gram-positive and Gram-negative bacterial pathogens. A total of four Pediococcus isolates (16.67%) showed strong attachment to HT-29 cells. In contrast to HDL-C and amylase, the serum levels of TC, TG and LDL-C were reduced and lipase was elevated significantly following administration of mother milk-derived Pediococcus isolates.

The Pediococcus isolates demonstrated good probiotic properties in particular cholesterol-lowering ability in mice. Thus, after more studies they can be considered as probiotic strain(s).

The principal aim of this study is to investigate the relationship between technological, marketing, organizational and commercialization risk management on new product development (NPD) performance.

Based on questionnaire, the data were collected from a sample of general automotive industry in Iran. Based on theoretical considerations, a model was proposed and descriptive statistic and hierarchical regression were used to measure the relationship between risk management factors and NPD performance.

Data analysis revealed that if organization can amplify their knowledge and information about risk and main factors that affect NPD process, not only can they do their work better but can also increase their ability to predict future happenings that affect performance.

First, due to the relatively small sample size, caution should be exercised when interpreting the results. Second, the data were collected from automotive producer in Iran, which may restrict to some extent generalizability of the findings.

The results suggest that managers should consider more attention to risk management. If managers spread the risk management in all aspects of the NPD project, total performance will be increased and it can develop the probability of NPD success. Also organizations should perform great market research due to best commercialization.

Past researches have presented complete information about NPD process. But identifying and considering the effect of the risk management parameters that are connected to the NPD process were the main thrusts to perform the study. In this paper, based on past research about risk management of NPD, the extra aspect of process that can improve total performance of NPD has been examined.

This paper experimentally examines the concept of intellectual capital in the Iranian space industries. The first objective of this study is to validate a model for assessing the relationships among some factors of intellectual capital and knowledge management; and organizational performance. The second objective is to evaluate the mediating role of some of them in the relationship between the intangible assets and organizational performance.

The research is designed to utilize a systematic sampling and survey method. Intellectual capital here is decided to be four items of human, structural, innovation and cultural capital while two items of “knowledge development and sharing” and “learning and knowledge application” are considered for knowledge management. The structural equation modeling approach is used to validate the research model.

These analyses suggest that human capital and structural capital are positively associated with organizational performance. The findings also indicate that both cultural capital and knowledge management practices fully mediate the effects of intangible assets on organizational performance while the latter does more.

This study adds to the literature in two valuable ways. First, it validates a model for assessing the associations among organizational performance and adoption of knowledge management and intellectual capital. Second, it offers important results on the identification of mediating role of cultural capital and knowledge management practices.

The purpose of this study is to propose a model to evaluate the performance of organizational units considering intellectual capital (IC) and employee loyalty approach applying principal component analysis and data envelopment analysis (PCA-DEA) method.

Organization units are considered as decision-making units, IC components including human capital (HC), structural capital (SC) and customer capital are inputs and employee loyalty is output. The principal component analysis was used to converts inputs and outputs into the independent variables. As a return to scale is variable, a modified envelopment input-oriented BCC model applied to obtain the efficiency of organization units. Also, all units of organization are ranked. Eventually, sensitivity analysis performed to show how input variables influence on output variable.

Operation, design and construction, production planning, internal affairs, quality control and security were recognized as efficient units. Also, units of operation, internal affairs and quality control ranked first to third, and the human resource unit earned the last rank. In addition, results of sensitivity analysis on input variables showed that the order of impact intensity is: customer capital, HC and SC, respectively.

Existence a framework for the development of human resource strategies and prioritization in the allocation of organizational resources to improve the performance of the organization considering human resources is vital. Most of the previous studies, just have examined the impact of IC on different dimensions of organizational performance. Meanwhile, evaluating the performance of IC with employee loyalty approach, using PCA-DEA simultaneously can evaluate and measure the impact of IC on the performance of the organization and its units regarding employee loyalty, which has a significant impact on improving the organization’s level of IC and human resource management.

This special issue of the Journal of Business & Industrial Marketing, entitled “Business, Industrial Marketing and Uncertainty”, presents selected extended studies that were presented at the European Academy of Management and Business Economics Conference (AEDEM 2012).

The main focus of this year was reflected in the slogan: “Creating new opportunities in an uncertain environment”. The objective was to show the importance that uncertainty has in our current world, strongly affected by many complexities and modern developments, especially through the new technological advances.

One fundamental reason that explains the economic crisis is that the government and companies were not well prepared for these critical situations. And the main justification for this is that they did not have enough information. Otherwise, they would have tried any possible strategy to avoid the crisis. Usually, uncertainty is defined as the situation with unknown information in the environment.

From a theoretical perspective, the problem here is that enterprises and governments should assess the information and the uncertainty in a more appropriate way. Usually, they have some studies in this direction, but many times, it is not enough, as it was proved in the last economic crisis.

This paper aims to inform the readers about the existing financial intelligence tools that are being used by financial intelligence units. It tries to demonstrate, with the help of a literature review, what the limitations of these tools are and how these limitations hinder the potential of the financial intelligence tools for early detection of terrorist financing activities.

The literature review method was adopted to discuss the financial intelligence tools, their limitations and the implications of the limitations for early detection of terrorist financing activities.

It was found that although the financial intelligence tools were introduced with a view to detect terrorist financing activities early, there are some inherent limitations of the tools relating to technical design features and operational procedures that hinder early detection of terrorist financing activities.

The existing financial intelligence tools need to be repaired by removing the inherent limitations of the tools.

The financial intelligence units should take into cognizance the importance of early detection of terrorist financing activities for preventing terrorist attacks and need to redesign the existing tools in such a way that make these tools effective for early detection of terrorist financing activities.

Peace will be established in society by preventing terrorist attacks through early detection of terrorist financing activities.

The originality of the paper lies in identifying the limitations of the existing financial intelligence tools for the early detection of terrorist financing activities.

In uncertain and emerging conditions, businesses must adopt new strategies to compete and survive the changing and unstable environment. This research seeks to investigate the role of dynamic capabilities in the competitiveness of startups, emphasizing resilience and strategic alignment.

Isfahan Scientific and Research Town has always been a pioneer in the field of science and technology in Iran and is known as the most extensive technology and knowledge-based complex in Iran. The sample size of 300 companies active in the startup field was selected using a simple random sampling method. Questionnaires were collected from the managers of technological startup companies in Isfahan, and the SEM model was used to analyze the data.

This research shows that dynamic capabilities in terms of coordination, flexibility and integration significantly impact competitiveness. Resilience and strategic alignment also increase the organization’s performance and strengthen the organization in gaining a more competitive advantage in the industry.

Finally, dynamic capabilities indirectly affect competitiveness through resilience and strategic alignment. This shows a need for strategic alignment and resilience to change advantage shape in dynamic conditions.

This paper aims to present a critical analysis of placemaking by the urban poor based on the Right to the City, Henri Lefebvre’s influential theory regarding the production of space and placemaking.

This study reflects Lefebvre’s production of space and the right to the city theories and containing three main pillars including holism, the urban and praxis, and the use of spatial dialectics. Also, for collecting information in this research, along with scrutiny of documents and books, residents of the poor settlements of Sanandaj have also been interviewed.

In Sanandaj, urban poor who lack formal housing reclaim the Right to City by creating informal settlements. Such settlements, such as Shohada, Baharmast and Tagh Taghan, cover 23% of the city’s area but house 69% of the urban population.

This research seeks to understand placemaking in urban slums by low-income inhabitants using Henry Lefebvre’s critical theory of social production of space and the Right to the City. This case study examines the city of Sanandaj, Iran, where most residents are poor and live in cooperative informal settlements. It illustrates how the urban poor, as marginalized inhabitants, overcome the constraints of conventional planning and property ownership to creatively and cooperatively develop communities that reflect their needs. This indicates a schism between formal and informal sectors.

The aim of this paper is to explain that what main characteristics financial technologies should have so that lead to improve the transparency of institutions and whether the integrated monetary banking system deployed in free-interest institutions has affected the transparency of these institutions in terms of those characteristics or not? In this study, the integrated monetary banking system will be studied subject to implementation of the Shafagh project.

Based on the literature review and the experts' opinions, the principles of the research questions were explained. Then, according to the dimensions of the research conceptual model, questions related to research questions were considered as the item for analysis in the modeling of structural equations. In the next step, 278 employees and managers of interest-free institutions were selected, by simple random sampling method, to answer the questionnaire. Data collected is analyzed by using structural equations method.

The results of the analysis indicates that the impact of the dimensions of strategic, technical, organizational and cultural factors – identified as the main characteristics of a financial system in this study – on the transparency of the transactions of the interest-free institutions is significant.

The results were obtained by focusing on the qualitative factors and also on the culture on free-interest institutions.

By investigating the issues and factors that the developers, consultants and institutions’ managers need to address and also giving a conceptual model, this study assists managers and generally financial institutions in developing an integrated banking system in a way that will be more likely to improve transparency in those organizations.

This study pioneers a comprehensive conceptual model, surpassing prior research that focused on isolated criteria. This novel approach enriches understanding of core banking systems' impact on financial transparency. This groundbreaking study uniquely focuses on free-interest institutions, traditionally presumed to be transparent but never before studied.
