SPE Strong: Strengthening Our Core: The Influential Yet Delicate Balance of Mentoring
Authors: Noonan Shauna
Published: February 2020

President's column

“The delicate balance of mentoring someone is not creating them in your own image, but giving them the opportunity to create themselves.”—Steven Spielberg

One of my focus areas as SPE President is strengthening the feedstock of incoming talent into our industry. In my January column, I talked about industrywide initiatives under way to attract and retain this talent. This month, I want to engage with our members on the importance of effectively mentoring these bright, young minds.

While I reflected upon setting my goals for the new year, I began to think about all of the important people in my career who not only helped me set high goals, but also provided support and guidance in achieving those goals. Some people were assigned to be my mentor, while others did it informally by providing advice during opportune moments. Truthfully, it does not matter how they became my mentor. The key point is that they were. Coaching a young professional in a technical position is critical to their success, but developing a person to have the interpersonal skills to navigate this industry is equally important.

For 2020, my goals include being both a mentor and mentee. While I believe I have much to contribute to our younger members, I also have much to learn. I want to encourage more of our members to set goals around mentoring and want to make this the month where we take time to recognize and thank those who have had a positive impact on us as our mentors.

Thank you, Don Patterson (retired Chevron), for mentoring me through my years of supervising workover rigs in northern Alberta. You were tasked with mentoring all the young engineers who were supervising rigs in northern Alberta, and phoning in our morning reports to you was often the most anxious part of our day. After looking back, your critiques were the necessary constructive feedback we needed. Fred Brownlee (retired Chevron) and John Patterson (retired ConocoPhillips) were two of my most influential mentors, both in helping me grow my technical skills and for connecting me with industry peers. Mike Mooney (retired ConocoPhillips) taught me how to be a great manager, how to conduct employee performance assessments properly, and how to set my focus on value-adding goals. Karen Draper (retired S&N Pump) and Carol Magney Grande (Magney Grande) provided mentorship on how to succeed in this industry as a working mother, and also gave me my first opportunity to serve on an SPE committee. Finally, I must thank Dr. Jeff Spath (SPE 2014 President). He became my mentor when I first served on the SPEI Board as a Technical Director and has continued to provide critical guidance and constructive feedback since. Without his help, I would not be writing this column as your 2020 SPE President.

Published: February 2020

Background: The movement of malaria vectors into new areas is a growing concern in the efforts to control malaria. The recent report of Anopheles stephensi in eastern Ethiopia has raised the necessity to understand the insecticide resistance status of the vector in the region to better inform vector-based interventions. The aim of this study was to evaluate insecticide resistance in An. stephensi in eastern Ethiopia using two approaches: 1) World Health Organization (WHO) bioassay tests in An. stephensi and 2) genetic analysis of insecticide resistance genes in An. stephensi in eastern Ethiopia. Methods: Mosquito larvae and pupae were collected from Kebridehar. Insecticide susceptibility of An. stephensi was tested with malathion 5%, bendiocarb 0.1%, propoxur 0.1%, deltamethrin 0.05%, permethrin 0.75%, Pirimiphos-methyl 0.25% and DDT 4%, according to WHO standard protocols. Results: All An. stephensi samples were resistant to carbamates, with mortality rates 23% and 21% for bendiocarb and propoxur, respectively. Adult An. stephensi was also resistant to pyrethroid insecticides with mortality rates 67% for deltamethrin and 53% for permethrin. Resistance to DDT and malathion was detected in An. stephensi with mortality rates of 32% as well as An. stephensi was resistance to pirimiphos-methyl with mortality rates 14%. Analysis of the voltage gate sodium channel gene (vgsc) revealed the absence of kdr L1014 mutations. Conclusion: Overall, these findings support that An. stephensi is resistant to several classes of insecticides, most notably pyrethroids. However, the absence of the kdr L1014 gene may suggest non-target site resistance mechanisms. Continuous insecticide resistance monitoring should be carried out in the region to confirm the documented resistance and exploring mechanisms conferring resistance in An. stephensi in Ethiopia.

Published: February 2020

Background: A retrospective study of patients with repeatedly recurrent spinal chordoma (RRSC) was performed. The objective of this study was to evaluate the independent prognostic factors for RRSC improving life expectancy and discuss the most appropriate treatment modality. Methods: Medical data and follow-up record of patients who were diagnosed as RRSC and were surgically treated in Changzheng hospital between July 2010 and September 2017 were reviewed systematically. Univariate and multivariate analysis were performed to identify possible independent prognostic factors for patients with RRSC. Recurrence-free survival (RFS) and overall survival (OS) were estimated by Kaplan-Meier method. Factors with P < 0.1 were subjected to multivariate analysis by Cox regression analysis. P < 0.05 was considered statistically significant. Results: Sixty-five consecutive patients with RRSC were included in this study. Local recurrence was detected in thirty-three patients, while death was occurred in twenty-one patients. The mean follow-up period was 34.3 months. The statistical results revealed that number of recurrence (NOR), surgical method, and surgical margin were independent prognostic factors for RFS and preoperative Frankel score (PFS) was favorable prognostic factor for OS. Moreover, subtype analysis suggested that treatment method could make significant difference for prognosis of patients with RRSC. Conclusion: Less NOR, total resection, and wide surgical margin could significantly reduce the risk of local recurrence of RRSC. PFS of A-C was adverse prognostic factor for OS. Total en bloc resection or total piecemeal resection with postoperative radiotherapy is recommended as ideal treatment method for prolonging life expectancy.

Published: February 2020

Background: To evaluate the influence of the location of endometrioma (right vs. left ovary) on endometriosis severity, we compared the revised American Society for Reproductive Medicine (ASRM) scores determined by laparoscopic surgery. Methods: The medical records of 151 patients, including 58 right-sided and 93 left-sided cases, who underwent initial laparoscopic surgery for unilateral ovarian endometrioma were reviewed retrospectively. We extracted the ASRM scores determined during surgery and some representative factors relating to endometirosis that are separate from tumour characteristics, such as the coexistence of uterine fibroid, adenomyoma, or other ovarian tumours, a history of assisted reproductive technology (ART), and tumour marker values. Multivariate analysis was performed to assess the impact of each factor. We classified the ASRM scores into 4 categories to compare the tendency towards endometrial lesion spread with a focus on the “sidedness” of the endometrioma. Opposite endometrial lesion (OEL), Douglas pouch endometrial lesion (DEL), same endometrial lesion (SEL) and peritoneal endometrial lesion (PEL) were defined. Results: The ASRM scores of patients with right-sided endometrioma were significantly higher than those of patients with left-sided endometrioma (41.5 ± 22.0 points vs. 33.5 ± 16.3 points, p<0.05). The higher ASRM scores of the patients with right-sided endometrioma may be caused by the frequent detection of endometrial lesions in the left-sided tube, left-sided ovary and Douglas pouch. Multivariate analysis revealed that the coexistence of uterine fibroid or adenomyoma also had significant positive impacts on increasing the ASRM score. Conclusions: Higher ASRM scores are possible in patients with right-sided endometrioma. The laterality of endometriosis severity should be considered.

Authors: Author) Anna Svedlund(New Corresponding , Tubic Bojan , Author) Anders Elfvin(Former Corresponding , Magnusson Per , Swolin-Eide Diana
Published: February 2020

Background: The aim of this prospective study was to investigate the potential influence of the fat mass and obesity-associated gene (FTO), SNP rs9939609, on body mass index (BMI) and body composition in women with severe anorexia nervosa during intensive nutrition therapy and after three years.

Methods: Twenty-five female anorexia nervosa patients (age 20.1±2.3 years, BMI 15.5±1.0 kg/m2) were treated for 12 weeks with a high-energy diet. FTO was genotyped and body composition parameters were assessed by dual-energy X-ray absorptiometry and peripheral quantitative computed tomography at baseline, after 12 weeks and at three-year follow-up.

Results: Patients gained, on average, 9.9 kg and BMI increased to 19.0±0.9 kg/m2 during intensive nutrition therapy. Fat mass increased, p<0.001, but total lean mass was stable. After three years, BMI remained stable, 19.4±3.3 kg/m2, as well as fat mass parameters and total lean mass. Muscle density decreased while the quotient fat/muscle area increased during nutrition therapy, but both then stabilized and remained stable after three years. There were no associations between FTO genotype and BMI or body composition parameters during the nutrition therapy or after three years. A tendency towards more stable BMI was observed in patients with the TT genotype and wider range in BMI for patients with the risk allele A after three years.

Conclusions: Irrespective of the FTO genotype, there was no difference in weight response during nutrition therapy, or at three-year follow-up. Hence, there is limited support for individualized therapy for anorexia nervosa based on FTO genotype.

Published: February 2020

Background C-reactive protein/albumin ratio (CAR) is a novel prognostic biomarker in several malignancies. This study was aimed to evaluate the clinical significance and prognostic value of CAR in patients with gastric cancer. Methods The data of 205 gastric cancer patients who underwent surgery was retrospectively reviewed. The association with the clinical features and prognostic value of CAR in gastric cancer was analyzed. The data of this study was combined with previous studies to further determine the prognostic value of CAR in patients with gastric cancer. Results Cox analysis revealed that preoperative CAR was an independent prognosis indicator in patients with gastric cancer. High expression of CAR indicated a shorter survival time than those with lower expression. CAR has a higher prognostic value in the 1-, 3-, 5-years of overall survival in patients with gastric cancer. However, CAR has no significant difference regarding the gastric cancer patients’ age, gender and TNM stage. The discriminated value of CAR in TNM stage of gastric cancer was moderate. A meta-analysis by combining previous data and our data showed that preoperative CAR was significantly associated with the overall survival of patients with gastric cancer. Conclusions This study demonstrated that preoperative CAR was an independent prognostic indicator in the patients with gastric cancer who underwent surgery.

Background: Osteoclasts are large terminal-differentiated cells with multiple nuclei and are the only cells with bone resorption activity in the body. The abnormal migration and differentiation of osteoclasts may accelerate bone absorption, a crucial process in the occurrence and development of osteoporosis. Regulating the differentiation and activation of osteoclasts is a breakthrough point for the prevention and treatment of osteoporosis. Coumarin derivative of 3-(4-methoxyl)-1-(2-(4-coumarin) prop)-2-en-1-one (MCPEO) was selected in this study. We aimed to investigate the effects of (MCPEO) on osteoclast differentiation. Methods: Bone marrow mononuclear cells (BM-MNCs) were collected from 6-week-old ICR mice and inoculated in vitro. BM-MNC and RAW264.7 cells were induced by the receptor activator of nuclear factor κ B ligand (RANKL) to differentiate them into osteoclasts. The cells were then added with 0.01, 0.05, 0.1, 0.5, and 1 μM MCPEO. The cell viability of differentiated osteoclasts was analyzed by methylthiazolyldiphenyl-tetrazolium bromide assay. The differentiated osteoclasts were detected by tartrate-resistant acid phosphatase (TRAP) staining. Miuse osteoclast activation was investigated by absorptive activity analysis. Filamentous actin (F-actin) staining was employed to identify the formation of F-actin rings in the differentiated mouse osteoclasts. The change level of critical transcription factors related to osteoclast differentiation was determined by Western blot analysis. Results: Data show that MCPEO affected the cell viability of differentiated osteoclasts, inhibited the formation of TRAP-positive polynuclear cells, and decreased the absorption activity and the formation of F-actin rings in the differentiated osteoclasts. Furthermore, MCPEO influenced the change level of crucial transcription factors related to osteoclast differentiation. Conclusions: MCPEO inhibited the differentiation of RANKL-induced BM-MNC and RAW264.7 cells into osteoclasts.

OBJECTIVE To describe epidemiology of viral hepatitis (including HAV, HBV and HCV) among men who have sex with men (MSM) aged between 18 and 45 years and living in Lazio, an Italian Region with about 5.9 million inhabitants whose main city is Rome. METHODS A sero-survey (cross-sectional study) was conducted as part of a screening and prevention campaign for improving control of viral hepatitis in Lazio. The study enrolled 1,100 MSM people participating to the campaign. Outcome measures were serology for HAV (anti-HAV IgG and anti-HAV IgM), serology for HBV (anti-HBs, anti-HBc and HBsAg), and serology for HCV (anti-HCV). Participants’ epidemiological features were assessed for potential association with outcomes. RESULTS We found a very low prevalence of immunity against HAV and a significant exposure to high-risk behaviours, suggesting that gay community of Lazio is an ideal setting for HAV outbreaks. Prevalence of different serology profiles for HBV suggests that waning immunity and escape to mandatory vaccination still represent a significant issue in patients older than 35 years. Moreover, waning immunity suggests that patients who were vaccinated at birth may show low antibody levels. Consistently with other studies, prevalence of HCV infection was very low among young MSM. CONCLUSION Tailored vaccine programme aimed at immunizing MSM are critical to improve control of HAV in our setting. Findings on HBV epidemiology suggest that there is a need to define a clear strategy to recover patients who escaped vaccination and inform clinicians on the need to booster subjects with low immunity and high risk of exposure, such as MSM. Finally, MSM in Lazio do not represent a special group for HCV neither in terms of risk of infection nor in terms of potential issues for therapy access.
Memes in English classes
Authors: Boa Sorte Paulo
Published: February 2020

Memes have been constantly created and shared online, as they appear to be potential sources for portraying different realities. This paper aims at analyzing the use of memes in English classes through the Theory of Multiliteracies (LUKE, 2000; COPE & KALANTZIS, 2000, 2008; ROJO, 2012). Possibilities of working with this digital text, which go beyond the simple linguistic decoding, are pointed out throughout this paper. The research methodology is based on documentary research (LAVILLE & DIONE, 1999) as an extension of literature review (MACHI & McEVOY, 2009). A theoretical overview is presented on the initial conceptions of memes according to the writings of Dawkins (1976) and new readings on this kind of text (LUKE, 2000; COPE & KALANTZIS, 2008; ROJO, 2012; CALIXTO, 2018; AUTHOR, in press). As a result, we have pointed out memes as tools that are geared towards developing critical and reflective English classes.

Improving Clinical Translation of Machine Learning Approaches Through Clinician-Tailored Visual Displays of Black Box Algorithms: Development and Validation
Authors: Wongvibulsin Shannon , Wu Katherine C , Zeger Scott L
Published: February 2020

Background

Despite the promise of machine learning (ML) to inform individualized medical care, the clinical utility of ML in medicine has been limited by the minimal interpretability and black box nature of these algorithms.

Objective

The study aimed to demonstrate a general and simple framework for generating clinically relevant and interpretable visualizations of black box predictions to aid in the clinical translation of ML.

Methods

To obtain improved transparency of ML, simplified models and visual displays can be generated using common methods from clinical practice such as decision trees and effect plots. We illustrated the approach based on postprocessing of ML predictions, in this case random forest predictions, and applied the method to data from the Left Ventricular (LV) Structural Predictors of Sudden Cardiac Death (SCD) Registry for individualized risk prediction of SCD, a leading cause of death.

Results

With the LV Structural Predictors of SCD Registry data, SCD risk predictions are obtained from a random forest algorithm that identifies the most important predictors, nonlinearities, and interactions among a large number of variables while naturally accounting for missing data. The black box predictions are postprocessed using classification and regression trees into a clinically relevant and interpretable visualization. The method also quantifies the relative importance of an individual or a combination of predictors. Several risk factors (heart failure hospitalization, cardiac magnetic resonance imaging indices, and serum concentration of systemic inflammation) can be clearly visualized as branch points of a decision tree to discriminate between low-, intermediate-, and high-risk patients.

Conclusions

Through a clinically important example, we illustrate a general and simple approach to increase the clinical translation of ML through clinician-tailored visual displays of results from black box algorithms. We illustrate this general model-agnostic framework by applying it to SCD risk prediction. Although we illustrate the methods using SCD prediction with random forest, the methods presented are applicable more broadly to improving the clinical translation of ML, regardless of the specific ML algorithm or clinical application. As any trained predictive model can be summarized in this manner to a prespecified level of precision, we encourage the use of simplified visual displays as an adjunct to the complex predictive model. Overall, this framework can allow clinicians to peek inside the black box and develop a deeper understanding of the most important features from a model to gain trust in the predictions and confidence in applying them to clinical care.

Electronic health records (EHRs) offer opportunities for research and improvements in patient care. However, challenges exist in using data from EHRs due to the volume of information existing within clinical notes, which can be labor intensive and costly to transform into usable data with existing strategies. This case report details the collaborative development and implementation of the postencounter form (PEF) system into the EHR at the Road Home Program at Rush University Medical Center in Chicago, IL to address these concerns with limited burden to clinical workflows. The PEF system proved to be an effective tool with over 98% of all clinical encounters including a completed PEF within 5 months of implementation. In addition, the system has generated over 325,188 unique, readily-accessible data points in under 4 years of use. The PEF system has since been deployed to other settings demonstrating that the system may have broader clinical utility.
Online Interventions for the Selective Prevention of Illicit Drug Use in Young Drug Users: Exploratory Study
Authors: Tomazic Tina , Jerkovic Olivera Stanojevic
Published: February 2020

Background

Digital technologies have a major impact on the daily lives of young people and are also used to seek information on and help with drug-related issues online.

Objective

The aim of this article was to analyze current online interventions for young drug users in Slovenia, with the purpose of contributing to the development of guidelines and key recommendations for effective online interventions.

Methods

This study was part of the project Click for Support. We performed a keyword search, received input from national experts in the field of drug prevention, and conducted an assessment of recognized national online interventions through workshop-based discussions with the target group of 20 young drug users.

Results

The current online intervention services in Slovenia are satisfactory but are still not sufficiently recognized. The most important issues for young drug users were the design and functionality of the online intervention, presence of a clear structure, possibility of using it on smartphones, comprehensive and quick professional feedback, and data security. Playful elements and the ability to share (experiences) with other or former users were also recognized as important.

Conclusions

With effective online interventions, we can include more young drug users, facilitate access to a more affordable service, provide quick professional feedback on patterns of consumption, increase knowledge about the effects and consequences of drugs, and support the reduction or cessation of drug use. From the public health perspective, it is challenging to provide drug interventions broadly to the target group and, hence, decrease inequities.

Published: February 2020

Perkembangan teknologi internet saat ini yang makin berkembang dengan pesat dari hari ke hari membuat layanan pada jaringan berbasis IP ini semakin diminati. Yang mengakibatkan menipisnya persediaan IPv4 sedangkan kebutuhan akan IP semakin bertambah. Maka dari itu, untuk memenuhi kebutuhan akan IP diciptakanlah IPv6. Dan sama seperti IPv4 untuk saling berkomunikasi di IPv6 dibutuhkan routing protocol. Ada beberapa routing protocol yang bisa digunakan pada IPv6. Beberapa diantaranya adalah Intermediate System-to-Intermediate System (IS- IS) dan IPv6 Open Shortest Path First version 3 (OSPFv3). IS-IS merupakan routing protocol publik yang menggunakan algoritma link state begitu juga dengan IPv6 OSPFv3 routing protocol juga menerapkan algoritma link state. Untuk pengujian dilakukan dengan melakukan akses video streaming yang melewati protocol routing yang diterapkan. Penelitian dilakukan pada network simulator dengan menggambarkan topologi jaringan yang menggunakan IS-IS dan OSPFv3. Dalam hasil simulasi ditemukan bahwa kinerja OSPFv3 lebih baik daripada IS-IS dalam hal delay, packet loss, throughput dan jitter. Tetapi dalam hal routing update IPv6 IS-IS lebih baik dari OSPFv3.

Dalam era data / internet, para operator telekomunikasi  tentu saja mulai memfokuskan bisnis dan layanannya pada data, yang semula hanya sebagai salah satu value added service (VAS) hingga kemudian menjadi bagian core business para operator. Sayangnya pada era data ini, sepertinya resiko yang dihadapi operator adalah harus berbagi “kue” revenue dengan “banyak pemain lain” di luar operator telekomunikasi. Kemungkinan nilai yang didapatkan tidak akan sebesar saat era voice dan SMS yang masih mendominasi layanan telekomunikasi saat itu. Tetapi pertumbuhan pendapatan terus tertekan. Untuk mengatasi resiko tersebut maka operator telekomunikasi perlu manajemen resiko yang lebih handal lagi
Antecedents and Consequences of Materialism: An Integrated Theoretical Framework
Authors: Duh Helen I.
Published: February 2020

Materialism has become an integral part of consumersâ€™ economic activities and modern day living, with mainly negative consequences reported from materialistsâ€™ lifestyle. Some of the reported negative consequences of materialism are increasing consumer debt and bankruptcy, shrinking saving, economic crisis and lower levels of life satisfaction and well-being. Consequently, economic psychologists, consumer researchers, sociologists and family psychologists are studying the antecedents of materialism, but there is yet to be an agreement as to how the construct should be defined and on what causes or predicts materialism. Critics of materialism have often seen only negative consequences and blamed marketing activities for the growth of materialism, but substantial academic literature and empirical studies report biological, social, cultural, socio-economic, psychological and even political factors driving materialism. There is therefore a need to develop an integrated and comprehensive theoretical framework, which delineates the various predictors of materialism. There is also the need to highlight the negative, as well as positive consequences of materialism for the interest of retailers, consumer interest groups and policy makers.

Today, the economic and social effects of the airports on the region they are located are widely accepted throughout the world including Turkey. In developing countries transportation sector is a significant tool of development. Since millennium there has been a great growth in the number of people who prefer air transportation in Turkey. The decrease in the cost of the transportation of both passengers and freight in air transport leads the increase of its accessibility. In this concept when a region has an active airport it helps to increase the regionâ€™s competitiveness and support its economic, social and cultural development. The aim of this study is to analyze whether an active airport and its traffic frequency have an effect on countryâ€™s macroeconomic indicators. In this study region - fixed effect and two stage least square (2SLS) models are applied with using panel data for 26 sub-regions at NUTS 2 level in Turkey period of 2004 - 2011. The results of this study support that increasing in number of active airports and its traffic frequency have a positive effect on regional economic growth.

The study tries to determine the association among corporate strategy, social structure and firm performance. In this regard, the monetary reports of 78 companies listed in Karachi Stock Exchange since 2007 to 2014 were scrutinized. In this research, firm strategy (sales growth, liquidity) and capital structure (debt ratio) were used as sovereign variables, and firm performance (return on equity, return on assets, free cash flow for the firm, free cash flow per share) were functional and are used as dependent variables, so to study the affiliation between corporate strategy, capital structure and firm performance within a 8-years period from 2007 to 2014. Secondary data has been used to test the hypotheses; single variable linear regression method was used and their significance was evaluated using Statistics T (t-test) and F (Fisher). The study results indicate that there is a significant positive relationship between sales growth variables and two types (among four types) of performance criteria in the study, namely return on equity and return on assets. And there is a positive significant relationship between firm liquidity and three criteria of firm's performance in the study namely return on equity, free cash flow per share and return on assets. Also, debt ratio has a positive significant relationship with free cash flow for firm and a negative significant relationship with return on assets.
The Economic Impacts of Tourism on the Local Community of Bergville, Kwazulu Natal, South Africa
Authors: Mabaso Simiso Lindokuhle
Published: February 2020

Tourism is playing an increasingly important role in the local and national economy. The outstanding beauty of the northern Drakensberg is a prime tourist attraction in KwaZulu-Natal, attracting a regular flow of tourists throughout the year (Okhahlamba Municipality, 2013). The primary objective of this research is to investigate whether the benefits of tourism that are supposed to be reaped by the local community of Bergville, exist. If so, what are these benefits? There might be people from the local community, who are working within the tourism sector, but what are the types of jobs that they do, their level of job-satisfaction, and the extent to which they are able to earn a living from employment within the tourism sector? Do they have the necessary skills and training to allow them to make a successful career within the tourism sector? The White Paper on the Development and Promotion of Tourism (DEAT, 1996), states that with any tourism development in the local communities, local people should be involved in the decision making. They should be trained if they lack the necessary skills required to participate in that development. All these issues are relevant to Bergville as the region has a lot of tourism development, and it is a place that integrates tourism and conservation.
Structural Breaks, Stability and Demand for Money in South Africa
Authors: Malumisa Sambulo
Published: February 2020

The paper tests the null hypothesis of a stable long-run money demand in South Africa over the period 1970-2013. We employ the Gregory-Hansen (GH) method to test for the possibility of structural breaks in the money demand function. The Johansen Maximum likelihood procedure is carried out to determine the cointegration vector from which existence of one cointegrating vector is supported. Also based on the GH criterion, there is existence of one cointegrating vector. GH proposes three structural breaks for the money demand function. Results suggest that endogenous breaks occurred in 1991 and 1994. The GH cointegration equations reject M1 whilst M2 and M3 pass and we proceed to estimate the error-correction model. Complemented by the CUSUM and CUSUM of squares, the tests carried out suggest that monetary policy shifts did not introduce instability.
Investigating the Relationship between Organizational Culture and Organizational Justice among Health Workers in Turkey
Authors: KAYA Servet
Published: February 2020

To achieve profits, management has to put in place several inputs. Of all the inputs, human resources or the employees are the most important and yet, the most unpredictable. Research has identified organizational culture and organizational justice as two factors enabling employee satisfaction. Upon, their identification, research has continued into these areas as two separate fields and has come up with several results. However, little is known on how these two interrelate and their effect on one another. This study sought to provide this information by investigating the correlation between these two factors. To do this, a cross-sectional survey was carried out among 223 health workers from a public hospital in Malatya, Turkey during May and June 2014. Out of a maximum of 20, organizational culture and organizational justice received mean scores of 11.4 Â± 2.3 and 14.0 Â± 4.8 respectively. Correlation analysis showed that almost all the domains of organizational culture had a statistically significant moderately positive relationship (0.434 â‰¤ r â‰¤ 0.636) with the domains of organizational justice with the exception of the power domain. This study finds a statistically positive correlation between overall justice scores and overall culture scores. However the correlation between them is moderate indicating that it is possible that other factors are equally or even more important in their determination. Thus, while managers can use organizational culture as an indication of organizational justice, they should not totally rely on one as a measure of the other.
