<p>The primary objective of the existing paper deals with to examine the relationship of hockey coaches and team cohesion with the performance of field hockey players of Pakistan and their impact on players’ performance. However the secondary objective was to measure the field performance of hockey players on practical measures. The research methodology is based on both descriptive and inferential statistical approaches. The descriptive data was collected in the form of field performance tests (technical skills and fitness capabilities) while the inferential data perceived by players was collected using survey questionnaire. A number of 296 national field hockey players of Pakistan were selected from 14 national departments of field hockey as samples. Descriptive statistics, correlation and multiple regression analysis were employed through SPSS (version 21.0). The results of the field performance tests were found below than average (weaker) in technical skills and fitness capabilities of national field hockey players of Pakistan. However, the findings of the inferential analysis revealed that hockey coaches and team cohesion have positive and significant relationships with the performance of field hockey players. Implications of existing study were also briefed.<strong></strong></p>

The existing paper deals with a primary objective; to examine the relationship between hockey coaches and performance of field hockey players in socio-interaction approach. The secondary objective was to measure the field performance of hockey players on practical measures. The research methodology is based on both descriptive and inferential statistical approaches. The descriptive data was collected in the form of field performance tests (technical skills and fitness capabilities) while the inferential data perceived by players was collected using survey questionnaire. Adopted field performance test measures and survey questionnaire were employed. 296 national field hockey players of Pakistan were selected from national departments of field hockey as samples. The field performance tests and the relationship were analyzed using descriptive statistics and Pearson’s correlation analysis respectively. The results of the field performance tests were found below than average (weaker) in technical skills and fitness capabilities. However, the findings of the inferential analysis revealed that all constructs of hockey coaches have significant positive relationship with all variables of performance of field hockey players. The significance level was found at the 0.01 (2-tailed).

Agents operating in unstructured environments often create negative side effects (NSE) that may not be easy to identify at design time. We examine how various forms of human feedback or autonomous exploration can be used to learn a penalty function associated with NSE during system deployment. We formulate the problem of mitigating the impact of NSE as a multi-objective Markov decision process with lexicographic reward preferences and slack. The slack denotes the maximum deviation from an optimal policy with respect to the agent's primary objective allowed in order to mitigate NSE as a secondary objective. Empirical evaluation of our approach shows that the proposed framework can successfully mitigate NSE and that different feedback mechanisms introduce different biases, which influence the identification of NSE.

ABSTRACT The professional environment in which accountants operate has, in recent years, become increasingly complex, leading to significant changes within the profession. Intensifying the need for this change are the pressures associated with the recent global financial crisis, changes in information and communication technology, and the continuous introduction of new accounting standards. Employers are calling for the increased development of “non-technical” skills, such as critical thinking and the ability to communicate and engage with clients, within current graduates in order to meet the needs of the evolving and dynamic profession (Kavanagh and Drennan 2008; Hancock et al. 2010). In order for this to occur, real integration of non-technical skills' development into the accounting curriculum needs to take place. This instructional case tries to achieve this, providing students with an opportunity to apply theoretical accounting concepts to the creation of their own business, while actively developing their group processing skills. The primary objective of the case is to provide students with an opportunity to acquire technical accounting skills concurrently with group processing skills and other non-technical skills. A secondary objective of the case is to encourage students to engage with the technical learning material in the introductory accounting curriculum. This paper describes the design of an Industry Perspective Workshop Program that incorporates the comprehensive integration of group processing skills and accounting-related content within an introductory accounting decision-making course.

Introduction: Rasburicase is a urate oxidase enzyme used for prophylaxis and treatment of hyperuricemia associated with TLS. The recommended dose of rasburicase is 0.2 mg/kg/day for 5 days; however, recent studies have demonstrated the effectiveness of a single rasburicase dose in prophylaxis and management of hyperuricemia associated with TLS. Our institution’s TLS guideline was updated to recommend the use of a single rasburicase dose (0.2 mg/kg). The primary objective of this study was to assess the efficacy of a single rasburicase dose in controlling uric acid (UA); the secondary objective was to evaluate the impact of the institutional TLS guidelines update on consumption and cost of rasburicase. Methods: This is a single center retrospective cohort study including all patients who received rasburicase from August 2012 to March 2016 at the National Center for Cancer Care and Research (NCCCR) in Qatar. Patients were divided into 2 groups based on the prescribed number of rasburicase doses (single dose vs multiple doses). Collected data included patients’ diagnosis, laboratory parameters rasburicase dose, duration, and number of dispensed vials. UA levels within 24 hours and on day 5 of initial rasburicase dose were evaluated. Risk stratification was determined according to institutional guidelines based on disease, white blood cell count, lactate dehydrogenase level, renal function, and UA level. Results: A total of 103 patients who received rasburicase were evaluated retrospectively; rasburicase was prescribed as single dose for 65 patients (63%) and multiple doses for 38 patients (37%). The majority of patients who received rasburicase as single or multiple doses were at high risk of developing TLS, representing 68% and 84%, respectively. Baseline mean UA levels were similar in both groups: 5.4±2.9 mg/dL vs 4.7±3.2 mg/L respectively (P=.7). Normal or undetectable UA levels were observed within 24 hours in 98% of patients in the single dose group and 100% of patients in the multiple doses group. All patients in both groups had normal UA on day 5 of rasburicase with relatively similar UA levels: 1.5±1.2 mg/dL vs 0.8±1 mg/dL (P=.18). Rasburicase consumption and cost were reduced by 42.5% after the guidelines update. Conclusion: The single rasburicase dose demonstrated efficacy in controlling serum UA levels. Updating the institutional TLS guidelines had a significant impact on rasburicase consumption and led to significant cost reduction.

e16042 Background: Cetuximab provides a clear clinical benefit in the treatment in patients with RAS wild-type mCRC irrespective of treatment line, but the best sequence is still under investigation. Methods: Patients with RAS wild-type mCRC (2011-2019) who received cetuximab therapy were retrospectively analyzed. They were stratified based on the cetuximab treatment sequence, into the 1st, 2nd, 3rd or later-lines groups. The primary objective was to investigate the impact on Cetuximab sequence (2nd vs. 3rd and later-line) in PFS and OS. As for patients received the 3rd or later-line cetuximab with irinotecan therapy after refractory to the prior 1st and 2nd-line combined chemotherapy with fluoropyrimidine, oxaliplatin, and irinotecan, they will get another PFS of 2nd-line chemotherapy (PFSchemo) besides the PFS of 3rd or later-line cetuximab compared with the cetuximab 2nd-line used patients. We combined the PFSchemo to the PFS of 3rd or later-line cetuximab, then compared with PFS of 2nd -line cetuximab to evaluate the primary objective in PFS. As for the OS of primary objective, we calculated it from start of the 2nd-line of treatment. The secondary objective was to compare the efficacy of cetuximab sequence (1st vs. 2nd and later-lines) in OS calculated from start of the 1st-line of treatment. Results: In total, 193 patients were included: 106 in the 1st, 41 in the 2nd, and 46 in the 3rd-line groups. No difference was observed in baseline characteristics as sex,age,site of primary tumour,number of metastatic sites in the three groups. The median PFS of the 2nd-line and 3rd or later-line groups were 7.1 (95% CI 6.39-7.80) and 13.87 months(95% CI 11.44-16.29) respectively. PFS of the 3rd or later-line group was significantly longer than that of the 2nd-line group (hazard ratio[HR], 0.552; 95% CI, 0.349 to 0.871; P = 0.01). Median OS was 17.8 months (95% CI 13.5-22.1) in the 2nd-line and 27.4 months (95% CI 20.69-34.16) in the 3rd or later-line group (HR, 0.597; 95% CI 0.341 to 1.043; P = 0.07) from start of 2nd-line therapy. The median OS was 28.17 months (95% CI 22.11-34.22) in the 1st-line group and 33.10 months (95% CI 26.88-39.31) in the 2nd and later-lines group (HR, 0.724; 95% CI 0.507 to 1.304; P = 0.075) calculated from the 1st-line of therapy. Conclusions: In a real-world cohort we found that later-line especially 3rd or later-line therapy of cetuximab, may be more benefit for patients with RAS wild type mCRC, as 3rd or later-line use of cetuximab give one more line therapy chance.

Object The primary objective of this study was to measure the incidence of concussion according to a relative number of athlete exposures among 25 male and 20 female varsity ice hockey players. The secondary objective was to present neuropsychological test results between preseason and postseason play and at 72 hours, 2 weeks, and 2 months after concussion. Methods Every player underwent baseline assessments using the Sport Concussion Assessment Tool-2 (SCAT2), Immediate Post-Concussion Assessment and Cognitive Test (ImPACT), and MRI. Each regular season and postseason game was observed by 2 independent observers (a physician and a nonphysician observer). Players with a diagnosed concussion were removed from the game, examined in the team physician's office using the SCAT2 and ImPACT, and sent to undergo MRI. Results Eleven concussions occurred during the 55 physician-observed games (20%). The incidence of concussion, expressed as number of concussions per 1000 athlete exposures, was 10.70 for men and women combined in regular season play, 11.76 for men and women combined across both the regular season and playoff season, 7.50 for men and 14.93 for women in regular season play, and 8.47 for men across both the regular season and playoff season. One male player experienced repeat concussions. No concussions were reported during practice sessions, and 1 concussion was observed and diagnosed in an exhibition game. Neuropsychological testing suggested no statistically significant preseason/postseason differences between athletes who sustained a physician-diagnosed concussion and athletes who did not sustain a physician-diagnosed concussion on either the ImPACT or SCAT2. The athletes who sustained a physician-diagnosed concussion demonstrated few reliable changes postinjury. Conclusions Although the incidence of game-related concussions per 1000 athlete exposures in this study was half the highest rate reported in the authors' previous research, it was 3 times higher than the incidence reported by other authors within the literature concerning men's collegiate ice hockey and 5 times higher than the highest rate previously reported for woman's collegiate ice hockey. Interestingly, the present results suggest a substantively higher incidence of concussion among women (14.93) than men (7.50). The reproducible and significantly higher incidence of concussion among both men and woman ice hockey players, when compared with nonphysician-observed games, suggests a significant underestimation of sports concussion in the scientific literature.

The research makes it possible to recognize the judgments of the users who are enrolled in the zero to always family modality and, in turn, establish the relationship they give to the program in the training of their children. The use of qualitative research for this proposal contributes or it establishes the relationship of describing and giving points of view to problems of the social educational and experiential context, the primary objective was to determine the degree of use by users of the program from zero to always family modality, in the municipality of Pamplona. It can be said that the application of this research contributes in part to diagnosing from a personal point of view the impact generated by the program in the training of minors, evidencing in it the theoretical, political and real positions in order to make them aware of the importance of training of children. The instruments used for families in certain rural areas who are the objects of study were semi-structured interviews; validated by experts from the area, they managed to produce key information for the analysis and triangulation. Thanks to the analysis units and the categories established in the interview, it was possible to focus and provide solutions to the objectives set, demonstrating the perception that the beneficiaries of the program of zero They always have in relation to the operation in rural areas of Pamplona. With the information obtained it is clear to establish the conformity of the operation of the program in terms of the role of care for families, the training of minors and the integration of society is thus how the show is getting on the right tide.

Many studies rely on air pollution modeling such as land use regression (LUR) or atmospheric dispersion (AD) modeling in epidemiological and health impact assessments. Generally, these models are only validated using one validation dataset and their estimates at select receptor points are generalized to larger areas. The primary objective of this paper was to explore the effect of different validation datasets on the validation of air quality models. The secondary objective was to explore the effect of the model estimates’ spatial resolution on the models’ validity at different locations. Annual NOx and NO2 were generated using a LUR and an AD model. These estimates were validated against four measurement datasets, once when estimates were made at the exact locations of the validation points and once when estimates were made at the centroid of the 100m×100m grid in which the validation point fell. The validation results varied substantially based on the model and validation dataset used. The LUR models’ R2 ranged between 21% and 58%, based on the validation dataset. The AD models’ R2 ranged between 13% and 56% based on the validation dataset and the use of constant or varying background NOx. The validation results based on model estimates at the exact validation site locations were much better than those based on a 100m×100m grid. This paper demonstrated the value of validating modeled air quality against various datasets and suggested that the spatial resolution of the models’ estimates has a significant influence on the validity at the application point.

Purpose: The primary objective of this study was to determine the change in the adherence questionnaire score from the initial pharmacist intervention to 60 to 90 days follow-up. The secondary objective of this study was to investigate the impact of the type of pharmacist intervention on questionnaire scores. Methods: Administration of an adherence questionnaire to guide interventions has become the standard of care for patients during appointments with clinical pharmacy specialists at 3 primary care clinics. Subjects who received a questionnaire between November 4, 2013, and January 15, 2014, were included. These subjects received a second questionnaire 60 to 90 days after the first questionnaire to identify changes resulting from the pharmacist’s interventions. A scoring system was utilized to quantify patients’ responses to both the preintervention and postintervention questionnaires. The type of intervention completed was determined at each pharmacist’s clinical discretion. Results: Adherence scores increased significantly 60 to 90 days after administration of the questionnaire with a pharmacist’s intervention. Medication reminders, simplifying medication regimens, discount program referrals, disease-state information, medication information, and therapeutic interchanges, all increased adherence scores. Conclusion: A standardized tool to assess and address adherence was effectively utilized by 9 pharmacists at 3 clinics. The use of a standardized tool to guide adherence interventions is an effective way to increase adherence to medication therapy.
