Daily milk weights from 1006 lactations on 775 Holstein-Friesian cows in 42 herds and monthly test-day weights from 102 540 lactations on 73 717 cows in 17 481 herd-year-seasons were used to study the influence of covariances among milk weighings within a lactation on three models for describing the shape of the lactation curve for individual cows. The models included a gamma function, an inverse quadratic polynomial function, and a regression model of yields on day in lactation (linear and quadratic) and on log of 305 divided by day in lactation (linear and quadratic). For each model, several variance-covariance matrices of the observation vector were used. Models were compared on the basis of squared deviations of predicted versus actual milk weights and on the correlation between predicted and actual weights through the lactation averaged over cows. Better predictions were observed when covariances among test-day yields were ignored while models could be ranked regression model, gamma function, and inverse quadratic polynomial function in order of best to worst. Heritability estimates for the parameters of the various models and for 305-d milk yield ranged from 0.11 to 0.30. Genetic correlations were estimated and predictions of correlated responses in 305-d yield from selecting on various combinations of parameters from each method were computed. The best combination of parameters of the gamma function gave a relative efficiency of 74.7% as compared to selection for 305-d yield alone. Key words: Lactation curves, covariances, Holsteins

Abstract. The objective of this study was to determine the genetic and non genetic effects on lactation curve traits determined by the incomplete gamma function of Wood (1967) for Holstein-Friesian cows in Morocco. Data analysed included 49262 monthly records of the test-day milk yield from 4888 lactations of 3932 cows at their 1st, 2nd or 3rd parity collected during 1990 and 1999 in 232 herds enrolled in the official milk recording. In general, lactation curve traits (A, B, C, peak time [Tmax], peak milk yield [Ymax], persistency and 305 day milk yield [MY305]) were affected by herd, parity, age at calving, season of calving and year of calving. Heritability estimates were low and varied from 0.01 for parameter A to 0.10 for Ymax. Genetic and phenotypic correlations among traits varied from −0.79 to 1.00 and from −0.80 to 0.96, respectively. Genetic correlations between MY305 and parameter C were negative, but those between MY305 and all the other lactation curve traits were positive. It was concluded that selection for high peak milk yield and persistency will result in higher 305 day milk yield.

The national total parental nutrition program with an emphasis on pediatrics started before several ago at Ministry of health hospitals In Kingdom of Saudi Arabia. The program covered several regions and consisted from the foundation of Intravenous Admixture and preparation of pediatric parenteral nutrition to administration and follow up of patients outcomes. In addition to the prior system, the new initiative project with the standardized formulation of pediatric’s parenteral nutrition is the complementary project of the parental nutrition for pediatrics. The project initiated to prevent drug-related problems of parental nutrition, improve patient clinical outcome and reduce the unnecessary economic burden on the healthcare system. It is the new system in the Middle East and Gulf counties in additional to Saudi Arabia. The initiatives are the systemic implementation of standardized pediatrics formulation using management project tools of starting new idea until finding in the ground.

The general administration of pharmaceutical care started potential pharmacy practice program. The program is part of accreditation professional’s process of national and international regulations. The adult’s parenteral nutrition was one of the critical programs. The most healthcare professionals are not familiar with the new system. The new initiatives system adult’s standardized concentration formulation of total parental nutrition as complementary to the previous one. The new formulation consisted of all parental nutrition requirements based on national and international standards. The new system can be converted as computerized physician orders. The new initiatives may implement as project management model over one year or less than that’s. The new system prevents nutrition-related problems, and medication errors, and improve clinical outcomes of the adults’ population in the Kingdom of Saudi Arabia.

Filipinos are a major part of the workforce in the Kingdom of Saudi Arabia with a population of almost one million. This article investigates the effects of gender segregation on Filipino workers and how they navigate their lives through systems imposed on them. In particular, it examines the Kafala system (administrative sponsoring system) used for recruiting migrant workers for GCC countries. This article suggests that contrary beliefs about gender segregation and dress codes, Filipinas found it empowering. However, this article also concludes that gender segregation and dress codes also lead to isolation and loneliness. In addition, it is concluded that the fate and contentment of the overseas Filipino workers are directly dependent on who sponsors them.

Patient and Family Rights (PFR) is a common chapter available in the Joint Commission International (JCI) Accreditation[i] (fifth edition) and Central Board for Accreditation of Healthcare Institutions (CBAHI) Standards for hospitals (second edition)[ii]. JCI Accreditation is a USA based international healthcare accrediting organization, whereas CBAHI is the Kingdom of Saudi Arabia based national health care accrediting organization. However, both these standards are accredited by Ireland based International Society for Quality in Health Care (ISQua), which is the only accrediting organization who “accredit the accreditors' in the world. In Patient and Family Rights (PFR) chapter of JCI Accreditation for hospitals, there are nineteen (19) standards and seventy-seven (77) measurable elements (ME) whereas in CBAHI Accreditation there are thirty one (31) standards, ninety nine (99) sub-standards and fifty (50) evidence(s) of compliance (EC). The scoring mechanism is totally different in both these accrediting organizations. The researcher has identified thirty two (32) common parameters from JCI Accreditation and CBAHI standards, intent statement, measurable elements, sub-standard and evidence of compliance. On the basis of these identified common parameters, the researcher has compared the Patient and Family Rights chapter in JCI Accreditation and CBAHI Standards. Methods: This is a comparison study (normative comparison) in which the researcher has critically analyzed and compared the Patient and Family Rights (PFR) standards of JCI (Joint Commission International) Accreditation of USA (United States of America) and CBAHI (Central Board for Accreditation of Healthcare Institutions) of the Kingdom of Saudi Arabia. Data Collection: Primary data are collected from the JCI Accreditation Standards for hospitals, fifth edition, 2013 and CBAHI Standards for hospitals of Kingdom of Saudi Arabia, second edition, 2011. Secondary data are collected from relevant published journals, articles, research papers, academic literature and web portals. Objectives of the Study: The aim of this study is to analyze critically Patient and Family Rights (PFR) Standards in JCI Accreditation and CBAHI Standards to point out the best in among both these standards. Conclusion: This critical analysis of Patient and Family Rights (PFR) Standards in JCI Accreditation and CBAHI Standards for hospitals clearly show that the PFR Standards in CBAHI Standards are very comprehensive than the JCI Accreditation standards.
