Organizational Learning and Organizational Resilience Knowledge Management as a Mediator in Public Organizations of Iran

The purpose of this article is the findings of the mediating effect knowledge management in the relationship between organizational learning and organizational resilience. The study adopts a cross-sectional design to collect data used to carry out mediation analysis. 28 public organizations in Iran were selected as the samples of this study. The survey was conducted among meddle and senior managers and respondents were asked to express the opinions related to the effects organizational learning as mediator in relationship between management and organizational resilience. Knowledge management had an effect on organizational resilience. Organizational learning did not have a direct effect on organizational resilience, except through the full mediation of Knowledge management. This suggests that without Knowledge management, public organizations of Iran may not improve their level of resilience. Utilizing a cross-sectional design with questionnaires is one of the limitations of this study. The results may be different in the private sector. A future research strategy that may overcome this limitation is one that involves longitudinal studies in which flow of study variables can be followed over time. In addition, using objective measures, archival data for some variables, may give results that are more objective.

Knowledge Management and Organizational Resilience Organizational Learning as a Mediator in Iranian Public Organizations

The purpose of this study is to report the findings of the mediating effect of organizational learning in the relationship between knowledge management and organizational resilience. The study adopts a cross-sectional design to collect data used to carry out mediation analysis. As samples of the study 28 Iranian public organizations were selected. The survey was conducted among middle and senior managers and respondents were asked to express their opinions concerning roll of organizational learning as mediator in relationship between management and organizational resilience. Knowledge management and organizational learning as well are effective on increasing organizational resilience. However, in terms of mediating role of organizational learning findings were not similar to the result of previous studies. Organizational learning as mediator cannot have effective roll in increasing organizational resilience. Utilizing a cross-sectional design along with questionnaire is one of the limitations of the study. The results may be different in the private sector. A future research strategy that may overcome this limitation is one that involves longitudinal studies in which flow of study variables can be viewed over time. In addition, applying objective data, measures, archival data for some variables, may lead in more objective results.

A cell-free SDKP-conjugated self-assembling peptide hydrogel sufficient for improvement of myocardial infarction

Biomaterials in conjunction with stem cell therapy have recently attracted attention as a new therapeutic approach for myocardial infarction (MI), with the aim to solve the delivery challenges that exist with transplanted cells. Self-assembling peptide (SAP) hydrogels comprise a promising class of synthetic biomaterials with cardiac-compatible properties such as mild gelation, injectability, rehealing ability, and potential for sequence modification. Herein, we developed an SAP hydrogel composed of a self-assembling gel-forming core sequence (RADA) modified with SDKP motif with pro-angiogenic and anti-fibrotic activity to be used as a cardioprotective scaffold. The RADA-SDKP hydrogel was intramyocardially injected into the infarct border zone of a rat model of MI induced by left anterior descending artery (LAD) ligation as a cell-free or a cell-delivering scaffold for bone marrow mesenchymal stem cells (BM-MSCs). The left ventricular ejection fraction (LVEF) was markedly improved after transplantation of either free hydrogel or cell-laden hydrogel. This cardiac functional repair coincided very well with substantially lower fibrotic tissue formation, expanded microvasculature, and lower inflammatory response in the infarct area. Interestingly, BM-MSCs alone or in combination with hydrogel could not surpass the cardiac repair effects of the SDKP-modified SAP hydrogel. Taken together, we suggest that the RADA-SDKP hydrogel can be a promising cell-free construct that has the capability for functional restoration in the instances of acute myocardial infarction (AMI) that might minimize the safety concerns of cardiac cell therapy and facilitate clinical extrapolation. © 2020 by the authors.

Implementation of policy, planning and institutional framework for sustainable forest management

With the international and national development of sustainable forest management (SFM) for protecting and conserving all forest functions and its biodiversity, also for improving of human wellbeing who related to forest, some criteria and indicators have been present. We used this tools and hierarchical framework, scoring, ranking, and weighting to assess implemented policies at SFM unit. This study has investigated policy, planning of participatory integrated management at Pachat village and adjacent forests. In our study we achieved the principle score (ps) of 0.32 as one of the SFM principles for the studied area. The same process could be introduced for other SFM units to compare the results, in order to find out how close they are to SF

The Effect of Cinnamon Extract on Spermatogenesis and

A total of 300 one-day old male broilers (Cobb 500) were randomly divided into four treatment groups. The groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kGy electron-beam irradiated diets. A total of 5 replicates were performed. The chemical composition of the diet was not affected by irradiation. Irradiation doses of 5 and 7 kGy completely eliminated microbial load in diets (P<0.05) and decreased the total aerobic and coliform counts in ileum and cecum at increasing rate at 14, 28 and 42 days of age (L: P<0.001; Q: P<0.0001). Total coliforms of the ileum decreased with the increased irradiation dose at 21 and 42 days of age (Q: P<0.0001). Lactobacillus counts improved with increased EBI dose, except for lactobacillus in cecum at 42 days of age. There was a linear increase in villus height (duodenum, jejunum, and ileum) with higher irradiation doses at 21 and 42 days of age. Additionally, a linear increase and a decrease in villus height:crypt depth were observed in the jejunum at 21 and 42 days of age, respectively (P<0.05). The villus height:crypt depth of duodenum and jejunum followed a linear increasing rate (Q: P<0.001) with the increased irradiation dose. Feed intake, mortality (all periods), body weight gain, and feed conversion ratio were similar between treatments at 1-14 and 14-28 days of age. Body weight gain, however, increased at a rising rate (Q: P<0.001), and feed conversion ratio decreased at a diminishing rate (Q: P<0.01) with higher irradiation doses during 28-42 and 1-42 days of age. The ileal digestibility of dry matter, organic matter, ether extracts, gross energy, and apparent metabolizable energy increased with the irradiation dose (Q: P<0.001). Our results indicated that electron-beam diet irradiation reduces microbial coliform counts and supports lactic acid producers in the gastrointestinal tract. Moreover, the ileal digestibility of nutrients, body weight gain, and feed conversion ratio improve with irradiation

Evaluating of forest sustainability affected by tribal forestry (Case study: Shoul Abad-Lorestan, Iran)

The Zagros forests, covering approximately 5.2 million hectares of area, is considered as vital part of natural resources in Iran. Regulated and precise management plans to manage the Zagros forests is crucial regarding to its economic and social circumstances. Applying the local forestry, involving people’s participation in a near future, can be rewarding provided by making the possibility of its implementation. In this study, in order to find a transient policy to preparing the Shoul Abad area (Located in Lorestan Province) for the participatory forestry, tribal (local) forestry is considered as the best tool that can help to record, revise, and correct this kind of forestry. A number of three districts including Kamargap (where the tribal forestry is being implemented), Hiyye (where the tribal forestry is not being implemented) and Darre-Dang were selected and analyzed by FAO criteria (e.g. investigating the forest resources, biodiversity etc.). The forest sustainability was calculated by analyzing the data (regeneration, canopy coverage and biodiversity) gathered from the districts, using SAS software. Comparing the mean groups was carried out using SNK test. The results showed that the forest sustainability is higher in Kamargap district. Hence, applying the tribal forestry is now proposed to manage the forests located in Shoul Abad-Lorestan
