This study aims to examine OL as a potential mediating variable in the relationship between IT and organizational performance. Organizational learning (OL) has been proposed as the mechanism to accomplish this task. Existing empirical research demonstrates that OL may indeed act as a mediator for the effect of IT on organizational outcomes. Also, existing literature discusses the use of technology in the organization, and the case for OL as the key knowledge process, and the intersection between technology and OL as a knowledge-based means for improving organizational performance. Many studies use a descriptive measure of OL despite the theory suggesting that a normative measure may be more appropriate. This study aims to address these concerns in a setting by using structural equation modelling (SEM) to compare the effectiveness of descriptive and normative measures of OL as mediating variables in knowledge-intensive organizations. Survey results support OL as a mediator between IT and organizational performance in addition to normative measures of OL outperforming descriptive measures. Implications for research and practice are discussed. To test the model, we will apply (SEM) structural equation modeling in the analysis of a moment structures (AMOS) on the empirical evidence collected from 218 Pakistani CEOs and top managers.

Nifty Bank Index has started trading in futures and options (F&O) segment from 13^th June 2005 in National Stock Exchange. The purpose of the study is to enhance the literature by examining expiration effect on the price volatility and price reversal of Underlying Index in India. Historical data used for the current study primarily comprise of daily close prices of Nifty Bank which is the only equity sectoral index in India which is traded in derivatives market and its Future contract value is derived from the underlying CNX Bank Index during the period 1^st January 2010 till 31^st March 2020. To check stationarity of the data, Augmented Dicky Fuller test was used. The study employed ARMA- EGARCH model for analysing the data. The empirical results revealed that there is no effect on the mean returns of underlying Index and EGARCH (1,1) model furthermore shows there is existence of leverage effect in the Bank Index i.e., negative shocks causes more fluctuations in the Index than positive news of similar magnitude. The outcome of the study specifies that there is no effect on volatility on the underlying sectoral index due to expiration days and also observed no price reversal effect once the expiration days are over.

The study aims to investigate the impact of ownership structure on corporate voluntary disclosure in the listed companies of Bangladesh. While many studies on the impact of ownership structure on voluntary disclosure have looked at developed and developing countries, few studies have been carried out in a transition economy. Using a three-step relative voluntary disclosure index, the study applies a multivariate analysis on the cross-sectional data for the year 2018. The findings indicate that the quality of voluntary disclosure in transition economy is still below average but has improved compared to findings from the previous literature. We found a significant inverse relationship between corporate voluntary disclosure and public ownership, while no significant relationships between voluntary disclosure and institutional ownership, director ownership, and foreign ownership have been found. The empirical findings of the study will provide evidence to promote the voluntary disclosure characterized by the ownership structures. The findings have important implications for both local and foreign investors as they make their investment decisions especially related to a transition economy. Besides, the findings will assist, not only the corporate executives in rearranging their reporting paradigm, but also the regulators and governments in similar transition economy in adopting and formulating their corporate policies and strategies.

This paper offers a critical review of a newspaper argument regarding the problems of high school education assessment for university entrance examination system in the United Kingdom. The media account raises three sets of questioning to hold that the nation's long-standing A-levels have failed and is no longer viable as a high-stakes test. However, it is found that the writer's argumentations involving misleading conceptions can be deconstructed because of invalid reasoning and unreliable evidence. So, it is proposed that a reasonable solution to replace the discredited A-level exams should be to adopt an eclectic approach for assessing candidates' multiple capabilities; performance, potentiality and critical thinking skills. These criteria for component-oriented assessments are designed to measure their high school academic achievements and intellectual capacity for tertiary education; in the process of such measurement, critical-logical reasoning abilities for sound judgment and problem-solving tasks should be incorporated with the basic precondition that each university possesses its own discretion for the determination of adequate proportions to reflect each of the assessment outcomes. It is, therefore, expected that this critical review will inspire the readers to understand aspects of assessment as an educational field and to confirm how seriously they may be misguided by a distorted media argumentation without substantive background knowledge.

Although a considerable amount of research on discourse signaling cues has been conducted in reading, little attention has been paid to such cues in the area of listening. Moreover, despite the solid evidence showing that cues have beneficial effects for reading comprehension, L2 listening research has produced mixed findings about the role of cues. Such discrepancies among these findings might be due in part to inadequate research methodologies as well as the idiosyncratic features of their experimental designs. However, no study, to date, has thoroughly examined the research designs of listening comprehension studies on cues. Consequently, this study critically evaluates the present state of research designs and reporting practices of studies investigating the role of cues in listening comprehension. The present study aims to provide insights into areas that require empirical attention and systematic investigation. It also seeks to encourage improved and refined research practices for future studies. This paper is organized as follows: It will first critically review the empirical findings regarding cues in the area of L1 listening comprehension. Second, it will present a critical evaluation of L2 listening studies on cues. Finally, it will address the major research design issues of currently available listening studies and provide suggestions for improvement in future research.

The present study examined the role of dialogue journaling in Korean students' English writing development. Thirteen Korean middle school students participated in a five-week dialogue journal writing program. The participants' English writing skills before and after their dialogue journaling were compared in terms of holistic and analytical scores of their English essays. The study also examined the changes in the participants' language use, as manifested in their dialogue journals. The results indicated the positive influence of dialogue journal writing on the participants' English writing skills in the areas of content and lexical fluency. As for the linguistic evidence that related dialogue journaling to English writing development, the three patterns of change in language use emerged from the participants' dialogue journals: a) raised awareness on grammar conventions, b) raised awareness on discourse conventions, and c) increased depth and richness in idea development. There were also three unhelpful factors associated with little improvement of English writing: a) lack in basic writing skills, b) repetitive use of identical sentence patterns, and c) lack in grammatical and lexical awareness. Overall, the results suggested that dialogue journaling could facilitate Korean students' English writing development when it creates authentic communicative interactions between the teacher and students.

Purpose: The purpose of this study is to analyze the trend of research on intervention using adiponectin and to find the utilization in nursing. Methods: A systematic literature review was conducted. From 2005 to 2009, the articles were searched electronically using the data base with the key words of adiponectin. The criteria for inclusion in review were 1) an randomized clinical trial (RCT), 2) human, 3) English or Korean language. Finally, 89 articles (41 domestic studies, 48 foreign studies) were included in the review. Results: The major findings of this study were as follows: 1) In domestic studies, subjects of obesity were 80.5%, and the most frequently used intervention were exercise (95.1%). 2) In foreign studies, there were interventions for subjects of obesity (55.1%), and diabetes (25.0%). 66.7% of studies were in medicine including 56.3% on medicine/hormone therapy. 3) Adiponectin was significantly increased in 31 domestic studies and 33 foreign studies. Conclusion: It needs to understand the influence of Adiponectin in nursing research and practice. The practical use of Adiponectin has to be considered in a sense that it may help determining the direction of the nursing research to provide more objective evidence for nursing practice.

Purpose: The purpose of this study was to provide a concept analysis of nursing leadership. Methods: The concept analysis process of Walker and Avant (2011) was used. A review of the literature was conducted using several databases, including PubMed, CINAHL, Ovid-Medline, DBpia, and KISS. The databases were searched using the following terms 'nursing leadership', 'nursing' & 'leadership', and 'nurse & 'leadership', and for studies published from January 2000 to March 2015. Strict inclusion and exclusion criteria were applied. Results: Analysis of these studies indicated nursing leadership attributes were individual growth, collaboration, nursing excellence, creative problem solving, and influence. The antecedents of nursing leadership were the individual maturity level, construction of mutual trust and confidential relationships, and a job requirement. The consequences were improvement in nursing productivity, development of a supportive work environment, and satisfaction with the nursing profession. Conclusion: The findings in this study provide a definite concept of nursing leadership. The findings also provide the theoretical evidence for the development of nursing leadership competencies in nursing students and professional nurses.

Ameloblastic carcinoma is a malignant form of ameloblastoma defined by histological evidence of malignancy in primary, recurrent, or metastatic tumor. Such a tumor is rare, and the maxilla is an unusual site. Due to its rarity, the characteristics of this tumor in the maxilla have not been well described. Case 1: A 55-year-old, ill-appearing Nigerian male presented to our center with left maxillary swelling of seven-year duration. The swelling had been slow-growing and painless until one year prior, when the growth became rapid and was coupled with severe pain. The swelling affected both oral function and facial esthetics, and the patient reported difficulty breathing. There was a maxillary, ulcerated swelling extending from teeth 12 to 18 and blocking the left nostril. The involved teeth were moderately mobile. Case 2: A 32-year-old male farmer presented with recurrent right maxillary swelling of six-year duration. Prior to this episode, he had undergone surgery for ameloblastoma (follicular type). The present swelling was fungating through the skin and protruding into the right nostril. Ameloblastic carcinoma is an aggressive odontogenic tumor that requires aggressive surgical treatment.

Objectives This study aimed to review studies in Korean medicine for fibromyalgia syndrome (FMS). Methods We conducted search across 3 electronic databases (Korean traditional knowledge portal, RISS, Oasis) to find studies for FMS in Korean medicine. Studies of Korean medicine for FMS were included and analysed. Results 15 studies were included. 2 studies were reviews and 13 studies were case reports. Total numbers of patients in case studies were 15. In case studies, acupuncture (100%), herbal medicine (76.9%), Korean physical therapy (69.2%), pharmacopuncture (53.8%), Chuna (46.1%) and moxibustion (30.7%) etc. were used. BL23 in acupuncture and CV12 in moxibustion were most frequently used. Gamisoyo-san in herbal medicine and visual analogue scale (VAS) in outcome measure were most frequently used. Conclusions This systematic review found encouraging but limited evidence of Korean medicine for FMS. I expect various trials such as randomized clinical trial or animal experimentation and more case reports. And systemic review for FMS in other national journals is needed.
