Benefits And Costs

The growing importance of cooperative relationships may currently be observed throughout the world. The vast majority of such relationships take the form of coopetition, i.e., the simultaneous existence of cooperation and competition between competitors. Previous research on coopetition characterizes these relationships mostly in the context of the benefits achieved. Researchers emphasize a number of benefits resulting from coopetition, e.g., stimulation of innovations of partners, development of the technology, obtaining complementary resources, entering new markets, or creating new products. However, when deciding to begin coopetition, companies should not only consider the benefits, but also the drawbacks associated with such relationships. This is due to the fact that disadvantages are inherent features of coopetitive relationships between competitors. The relationship between the duration of cooperative relationships in particular areas and the benefits and costs associated with these relationships is scarcely researched. Using a sample of 210 companies operating in the high-tech sector in Poland, we aimed to cover this gap in the knowledge base and to analyze this aspect of coopetition. Several research methods including multidimensional correspondence analysis, correlation analysis of qualitative variables, a chi-square test, multi-table analysis, and association rules were applied. The results of our research showed that coopetition is a viable strategy which contributes to the sustainable development of firms. We also found that the duration of coopetitive relationships in different areas of company activity is related to different types of benefits to collaboration partners.

Research Gap

This article undertakes the research problem of the assessment of the significance of poverty as a social challenge for local self-government units, and the differences in the assessment of the incidence of this phenomenon depending on the type of municipality. The authors also analyse the relationships between the ageing of the population and the assessment of the extent of poverty by municipalities. It must be pointed out that the undertaken problem has not been a subject of in-depth analysis thus far. Hence, this article fills the identified research gap in this field. The empirical part is based on the results of our own research, conducted using the Computer-Assisted Web Interview (CAWI) method on a sample of 144 municipalities of the Małopolskie Voivodship (Poland). In order to verify whether there is a relationship between the researched qualitative variables, the chi-square test of independence was used. In order to determine the relationships occurring between the categories of variables characterising the scale of the incidence of poverty and the remaining variables, a correspondence analysis was conducted. The research enabled us to find the issue of poverty to be one of the most important social problems from the point of view of municipalities. It is also worth noting that the degree of ageing in the population has an impact on the assessment of poverty among the elderly.

ABSTRACT Purpose: to analyze whether deleterious oral habits can influence the number of attempts of forced spirometry maneuvers performed by healthy children. Methods: this observational and cross-sectional analytical study included 149 healthy children aged 6-12 years attending public and private schools in Florianópolis, SC, Brazil. A validated protocol was applied for the analysis of deleterious oral habits. The children were grouped according to the number of spirometry maneuvers needed to achieve successful spirometry results, as follows: G1) children who needed 3 maneuvers; G2) 4 maneuvers; G3) 5-8 maneuvers. Data were analyzed with the Kolmogorov-Smirnov test and the Kruskal-Wallis test was applied to compare quantitative variables between the groups. The Chi-square test was used to assess the association between the groups and qualitative variables. Results: there was no association between the number of attempts and the qualitative variables evaluated by the protocol. There was also no difference between the groups regarding quantitative variables for breastfeeding time, breastfeeding occurrence, use of pacifiers, and thumb sucking. Conclusion: the presence of DOH did not influence the number of forced spirometry maneuvers, performed by the healthy children in this study.

Background: Uterine synechiae refers to a total or partial union of the inner walls of the uterus resulting from endometrial trauma. It is a cause of reproductive failure. Until now, synechia was not optimally treated and has remained understudied in Cameroon. Objective of present study was to Evaluate the diagnostic, therapeutic and prognostic aspects of uterine synechiae treated by hysteroscopy.Methods: We conducted a descriptive cross-sectional study with an analytical component from January 1st 2015 to July 31st 2017 at Yaounde. All patients diagnosed with uterine synechiae and treated with hysteroscopy were our sample. Sampling was consecutive. The chi-square test was used for the comparison of qualitative variables and Fisher's test for ANOVA variance analysis. The comparison of the averages was made by the Student's test. P-value less than 0.05 was considered as statistically significant.Results: Hysteroscopies were indicated for uterine synechiae in 14.50%. Nulliparous were 56.67%. A history of curettage/aspiration was present in 66.66%. All of the patients had a form of infertility and 83.33% had menstrual disorders. Hysterosalpingography showed a better sensitivity (88%). After hysteroscopic treatment, 63.30% had a complete anatomical restitution. There is a significant correlation between the stage of severity of synechia and anatomical restitution (p=0.008; Spearman correlation coefficient=-0.477).Conclusions: Uterine synechiae represent one-sixth of all indications for hysteroscopy and present clinically as menstrual disorder associated with infertility. A past history of uterine curettage is common. Hysterosalpingography has a better preoperative diagnostic sensitivity. Hysteroscopy allows optimal treatment.

ObjectiveThis study is concerned with helping to improve the health and care of newborn babies in Bangladesh by exploring adverse maternal circumstances and assessing whether these are contributing towards low birth weight (LBW) in neonates.Study designs and settingsData were drawn and analysed from the Bangladesh Demographic and Health Survey, 2014. Any association between LBW and adverse maternal circumstances were assessed using a Chi-square test with determinants of LBW identified by multivariate logistic regression analysis.ParticipantsThe study is based on 4728 children aged below 5 years and born to women from selected households.ResultsThe rate of LBW was around 19.9% (199 per 1000 live births) with the highest level found in the Sylhet region (26.2%). The rate was even higher in rural areas (20.8%) and among illiterate mothers (26.6%). Several adverse maternal circumstances of the women included in the survey were found to be significant for increasing the likelihood of giving birth to LBW babies. These circumstances included the women being underweight (adjusted odds ratio (AOR) 1.26, 95% CI 1.06 to 1.49); having unwanted births (AOR 1.22, 95% CI 1.03 to 1.44); had previous pregnancies terminated (AOR 1.28, 95% CI 1.05 to 1.57); were victims of intimate partner violence (AOR 1.23, 95% CI 1.05 to 1.45) and taking antenatal care <4 times (AOR 1.23, 95% CI 1.03 to 1.48). Other important risk factors that were revealed included age at birth <18 years (AOR 1.42, 95% CI 1.11 to 1.83) and intervals between the number of births <24 months (AOR 1.25, 95% CI 1.01 to 1.55). When taking multiple fertility behaviours together such as, the ages of the women at birth (<18 years with interval <24 months (AOR 1.26, 95% CI 1.02 to 1.57) and birth order (>3 with interval <24 months (AOR 1.68, 95% CI 1.18 to 2.37), then the risk of having LBW babies significantly increased.ConclusionThis study finds that adverse maternal circumstances combined with high-risk fertility behaviours are significantly associated with LBW in neonates. This situation could severely impede progress in Bangladesh towards achieving the sustainable development goal concerned with the healthcare of newborns.

ABSTRACT Background The diagnosis of sarcopenia is based on the analysis of strength, functionality and muscle mass. The objective was to verify the factors associated with sarcopenia in institutionalized elderly. Methods In total, 219 elderly individuals (≥60 years old) living in long-term institutions in Natal/RN were included in the study. After defining the elderly as sarcopenic or non-sarcopenic, anthropometric, biochemical, sociodemographic and health-related were analyzed. The Student t-test and Mann–Whitney test were used to analyze the quantitative, while the chi-square test was used for the qualitative variables. Finally, Poisson regression was used to provide prevalence ratios for those variables that presented differences in the bivariate analyses. Results Physical capacity and anthropometry were associated with sarcopenia. For each 1 cm of knee height, the elderly presented 2.71% more chance of not having sarcopenia, and eutrophic or overweight individuals (according to BMI) presented 37.71 and 91.81% chances, respectively, of not presenting sarcopenia. Elderly individuals who ambulate have a 30.08% chance of not being considered sarcopenic. In addition, biochemical and anthropometric indicators demonstrated a relationship of sarcopenia with malnutrition. Conclusion Sarcopenia is associated with a loss of body mass, not only selective muscle mass, and greater physical inability to ambulate.

Background: Celecoxib is widely used in post-operative cases because of its ability to reduce postoperative opioid drug use. Currently, the use of this drug is common in post-operative cases. In various studies, pregabalin was used for the management of pain after spinal surgery to reduce the need for opioids. Objectives: Since the treatment of tibia fractures and surgery is painful and has a long-term recovery, this study aimed to compare the effect of two drugs (pregabalin and celecoxib) on pain severity at 24 h postoperatively in patients having tibia fracture surgery. This would mark significant progress in taking the proper drug. Methods: In this probability clinical experiment, the sample consisted of 50 patients scheduled for tibia fractures, who were selected from the table of random numbers. Then, the patients were assigned into two groups: celecoxib (Group C) and pregabalin (Group P). In the first group, celecoxib was administered to patients at 1 h pre-operatively at a dose of 200 mg and 1 h post-operatively at a dose of 200 mg. In the second treatment group, patients received pregabalin at 1 h pre-operatively at a dose of 200 mg and 1 h post-operatively at a dose of 200 mg orally. Then VAS (visual analog scale) scores were recorded at 6, 12, and 24 h after surgery. Finally, using SPSS software, qualitative variables were compared according to their percentage by the Chi-square test. For quantitative analysis of variables, the mean value of each group was calculated. The comparison of means was made by t-test. Results: The VAS score was considerably lower at 24 hours after surgery in the pregabalin group than in the celecoxib-treated group. However, after 6 and 12 h of surgery, no statistically meaningful difference was observed. A less analgesic effect was observed in the group treated with celecoxib than pregabalin, which was statistically significant. Conclusion: Pregabalin improves postoperative pain, and it has more analgesic effects than celecoxib.

Background: Despite the many studies on running-related injuries (RRIs), risk factors for injury remain unclear in the literature. Purpose: To investigate the risk factors of RRIs. Study Design: Case-control study; Level of evidence, 3. Methods: An online survey was conducted among 3669 injured and noninjured runners. Injury was defined as pain of various kinds, without attention to its consequences on running practice. The survey included 41 questions on 5 main categories—personal characteristics, daily lifestyle, training and running characteristics, practice of other sporting activities, and prevention habits—as well as information about the occurrence of RRI over the previous 12 months. Continuous and qualitative variables were analyzed by Student t test and chi-square test, respectively. Sixteen variables were selected for multivariate binary logistic analysis. Results: Among the 3669 runners, 1852 (50.5%) reported at least 1 injury over the previous 12 months. Overuse injuries were largely represented (60.6%). The variables associated with RRIs that remained significant in the fully adjusted model were previous injury (odds ratio [OR], 1.62; 95% CI, 1.42-1.86), higher weight (OR, 1.006; 95% CI, 1.00-1.012), competitive running (OR, 1.53; 95% CI, 1.19-1.98), running >2 h/wk (OR, 1.28; 95% CI, 1.01-1.62), running >20 km/wk (OR, 1.25; 95% CI, 1.001-1.55), and stretching before running (OR, 1.46; 95% CI, 1.25-1.71). Conclusion: Previous injury remains the most relevant risk factor for RRIs according to the current study and previous data. Many training characteristics seem to be involved but still have to be confirmed in view of conflicting data in the literature. Further research would help clinicians better understand RRIs and how to prevent them.

Objective: The goal of the study is to check the degree to which the physicians and pediatricians can apply ESPGHAN and WGO criteria of celiac disease (CD) on their patients in Karbala city. Methods: This is a cross-sectional study conducted in Karbala city hospitals (Al-Hussein-medical city hospital, the pediatric teaching hospital) for the period from August 2017 to February 2018. A random selection of one hundred eight CD patients was carried out and the clinical data including the biopsy results were collected directly from patients or their family members via a questionnaire sheets. Statistically, the quantitative variables were analyzed using non-parametric t-test and the qualitative variables were analyzed using Chi-square test. Results: The study shows that of the total 108 patients, only n=43 (39.8%) of candidates who did biopsy even with tTG IgA>10 fold ULN (200 RU/ml and more) due to the shortage in EMA/HLA tests recommended by ASPGHAN to omit duodenal biopsy., while n=51 (47.2%) accomplished only one of the triple tests (only tTG IgA>10 fold ULN) suggested by ASPGHAN and then applied challenge test and n=14 (12.9) achieved non of the triple tests (tTG IgA antibody titer>5 fold ULN, but <10 fold ULN). On the other hand, the WGO guideline is more suitable if properly applied as it considers tTG (IgA) a convenient substituent of EMA test where high tTG (IgA) serum level being diagnostic and to be confirmed by the available DGP (IgA and IgG) antibodies. Conclusion: The WGO guideline for symptomatic and asymptomatic patients is more applicable for the areas with limited facilities, while ESPGHAN guideline for pediatrics can be applied to a less degree. Generally in Iraq there is a delay in disease diagnosis due to many reasons to be evaluated.

The Relationship

As an important part of the sustainable development of agriculture in China, cooperatives have become a hot topic. However, previous literature has mixed results on the relationship between quantity growth and service supply effect of cooperatives. By conducting multiple correspondence analysis, descriptive statistics, and Pearson’s chi-square test on survey data of 785 farmers, this paper aims to describe the characteristics of cooperatives’ members and evaluate the current state of cooperatives’ service supply from a demand-supply perspective. The results of the survey show that male, middle-aged, and middle-class farmers or farmers who plant local optimal crops are more likely to become the members of cooperatives. There is a huge gap between service supply and demand of farmers; cooperatives have a positive effect on reducing the degree of service demand. This effect is only significant when concerning sale, pest control, and mechanization. On the whole, there is a weak correlative relationship between the current service supply of cooperatives and the service demand of farmers in China.
