Ketoksikan Beberapa Racun Hamama dan Piretroid Timan terhadap Hamama Lelabah Merah, Tetranychus urticae Koch Kompleks

The toxicity of four acaricides and five synthetic pyrethroids against red spider mite, Tetranychus urticae Koch complex, was evaluated in the laboratory using the slide-dip technique. Mortality was recorded at 48 h post treatment and data were subjected to probit analysis. Based on the LC50 values, the order of toxicity of the chemicals tested was as follows: amitraz > deltamethrin = cypermethrin (CymbushR ) = fenvalerate > cypermethrin (RipcordR) > permethrin > bromopropylate = chinomethionate > azocyclotin. The LC50 value for amitraz was 2.5 ppm while for chinomethionate it was 37.5 ppm. Repeated tests on the toxicity of the pyrethroids using leaf dip technique at the LC50 and LC95 values obtained earlier from the slide-dip technique revealed a lower level of mortality. The highest mortality obtained was 21.0% from fenvalerate treatment at the LC95 value. Thus test techniques were found to give different toxicity values on the red spider mite

The impact of logistics service quality (LSQ), relationship marketing (RM) and relationship power (RP) on customer satisfaction in the Jordanian third party logistics (3PL) industry from customers’ perspective.

Logistics Service Quality (LSQ), Relationship Power (RP) and Relationship Marketing (RM) are regarded as the most important criteria leading to customer satisfaction in the third-Party Logistics (3PL) industry. This research investigates the impact of trust and commitment as the major relationship marketing constructs used to examine the quality of relationship between the 3PL provider and the 3PL customer, namely business-to-business context. Also, the study explores the effect of coercive power and reward power as the major dimensions of relationship power on customer satisfaction. In addition, the study investigates the effect of ordering procedures and personnel contact quality as the main variables of logistics service quality on customer satisfaction. The objectives of this study are to investigate the effects of personnel contact quality, ordering procedures, trust, commitment, coercive power and reward power on customer satisfaction in the third-party logistics industry in Jordan. A quantitative approach has been conducted in this study, using questionnaires to collect data from 243 third-party logistics customers in Jordan. The findings of the research indicate that there is a positive relationship between relationship marketing (trust, commitment) and customer satisfaction in the Jordanian third-party logistics industry. The same goes for logistics service quality (personnel contact quality, ordering procedures). For the relationship power, the results demonstrate that reward power has a positive impact on customer satisfaction, whereas there is a negative relationship between coercive power and customer satisfaction. The dimensions of relationship marketing (trust and commitment) have the strongest impact on customer satisfaction in the third-party logistics market in Jordan and it is followed by reward power. The study contributes to knowledge as it is the first study that explores the effect of relationship power on customer satisfaction in the third-party logistics industry. The managerial implications resulting from this study are beneficial to practitioners willing to work in the third-party logistics in Jordan or those working currently in this industry in Jordan

The role of a trustee in Sukuk: the Malaysian perspective

In Malaysia, the legal and regulatory framework governing Islamic Capital Market industry provides for trust structure insukuk. Trustee plays an important role in sukuk. In fact in everysukuk issuance save for the issue or offer which comes under the exceptions provided for under Schedule 8 of the Capital Market Services Act 2007 (“CMSA”), a trustee is required to be appointed and a trust deed to be executed. Thus, trust structure is central in sukuk, so far as Malaysia is concerned. This paper studies the important roles of trustees in sukuk, its nature and the extent of powers and duties of trustees appointed therein. Itexamines the categories of trustees in sukuk and their designated functions as well the nature and extent of powers and duties of a trustee with an insight on the current practices in the Malaysian Islamic Capital Market industry dealing with trust structure insukuk. The study will also look at other relevant aspects in trust structure, which include the trust deed as the constitutive document and the role of trustee in the event of default of sukuk

Students` Islamic personality on amanah: a structural modelling approach

The purpose of this study is to investigate the factorial structure of the Ummatic Personality Inventory (UPI). One of the constructs in UPI, Amanah was measured to understand the relationship among the factors namely, Amar Maaruf, Nahi munkar, Accountability to Allah and Accountability to Society. The sample of this study was a group of female students (n= 287) in a government school. Data were analysed using the Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM). The findings for the structural model revealed that Khalifah and Accountability correlated to the Amanah. The percentage of variance accounted for by the independent variable was 63% accordingly, which indicated a very good effect size. This reflects that accountability of people for enjoining good deeds is moderately related to accountability towards society. The act of forbidding evil has a strong direct effect on accountability towards Allah. Thus, more efforts should be put on educating students to forbid evil-doing (nahi munkar). In future, a deeper analysis of this nature could be made on the other two constructs of UPI

The relationship between lactate dehydrogenase (LDH) level in blood and the duration of transient tachypnea of the newborn.

Objective: Transient tachypnea of the newborn TTNB is a common cause of respiratory distress in postnatal period.  Although TTNB is a self-limited condition in most times , there are rare cases of more serious complications. We cannot predict the course of the case since the earlier hours of hospitalization , so this study importance is to investigate the relationship between LDH level in blood and the course  of TTNB (the duration of  hospitalization , and the incidence of complications). Material and methods: The study included 120 infants with TTNB which was diagnosed clinically and on the basis of laboratory  and chest-x rays results, patients were divided into two subgroups: the first one included infants with a normal LDH level in blood, and the other one included infants with a high LDH level in blood, the duration of hospitalization and the incidence of complications were compared between the two groups. Results: The duration of hospitalization in infants with a high LDH level is longer than the duration of hospitalization in infants with a normal LDH level, and the duration of hospitalization increases as the value of LDH increases. The incidence of complications in infants with a high LDH level is more than the incidence of complications in infants with a normal LDH level, and the frequency of complications increases as the value of LDH increases. Conclusions: There is a positive correlation between the LDH level in blood and the duration of hospitalization and the incidence of complications in infants with TTNB هدف الدراسة : تعتبر الـزلة التنفسية العابرة عند الوليد (TTNB (Transient tachypnea of the newborn  سبباً شائعاً للاضطراب التنفسي عند الولدان بفترة بعد الولادة ، وعلى الرغم من أن الـ TTNBحدثية محددة لذاتها بأغلب الأحيان إلا أنه هناك حالات نادرة لاختلاطات أخطر، وبما أننا لا نستطيع التنبؤ بسير الإصابة منذ الساعات الأولى للاستشفاء تأتي أهمية الدراسة في تقييم العلاقة بين مستوى الـ LDH(Lactate dehydrogenase) في الدم مع تطور الزلة التنفسية العابرة عند الولدان (مدة الاستشفاء _حدوث الاختلاطات ). المواد و الطرائق : شملت الدراسة 120 وليداً تم استشفاؤهم باستطباب زلة تنفسية عابرة TTNB مشخصة سريرياً ومخبرياً وشعاعياً ، تم تقسيمهم إلى مجموعتين : الأولى (ولدان قيمة LDH الدم لديهم طبيعية ) والثانية (ولدان قيمة LDH الدم لديهم مرتفعة) وتمت مقارنة مدة الاستشفاء وحدوث الاختلاطات بين المجموعتين. النتائج : مدة الاستشفاء عند الولدان مع معدل LDH فوق الطبيعي هي أطول من مدة استشفاء الولدان مع معدل LDH  طبيعي ، مع ازدياد مدة الاستشفاء كلما كانت قيمة LDH الدم أعلى ، والاختلاطات عند الولدان مع معدل LDH فوق الطبيعي هي أكبر منها عند الولدان مع معدل LDH طبيعي ، ويزداد تواتر حدوث الاختلاطات مع ارتفاع قيمة LDH الدم عند الولدان. الاستنتاجات : توجد علاقة إيجابية بين مستوى LDH الدم مع مدة الاستشفاء عند ولدان الزلة التنفسية العابرة وكذلك مع حدوث الاختلاطات عنه

The relationship between Meconium stained amniotic fluid and early neonatal sepsis.

Introduction: Meconium stained amniotic fluid can either occur as a physiologic event due to increasing gestational age or it may be pathological, indicating fetal distress, and because of the prevalence of early neonatal sepsis and the risk of late diagnosis, the study aims at determining the prevalence of early neonatal sepsis with amniocentesis, determining the risk factors for amniotic fluid suspension, and the possible association between these predisposing factors and early bacterial neonatal sepsis . Patients and methods: 46 neonates with meconium stained amniotic fluid were investigated for sepsis and dividing them into two groups according to the presence or absence of risk factors and studying the association of sepsis with these factors. Results :There was a strong positive correlation between the presence of possible fetal factors for the occurrence of congenital infection and early neonatal sepsis, a moderately strong relationship between the presence of parental factors to meconium stained amniotic fluid and early neonatal sepsis. Conclusions: The prevalence of amniocentesis in neonates is associated with the presence of potential fetal and parental factors for amniocentesis and early neonatal sepsis المقدمة : يحدث تعقي السائل الأمنيوسي ( Meconium stained amniotic fluid) بشكل فيزيولوجي عند زيادة العمر الحملي أو يكون مؤشراً على وجود الشدة حول الولادة ، وبسبب انتشار الإنتان الباكر عند الوليد (Early neonatal sepsis) وما يترتب عليه من مخاطر بسبب التأخر في التشخيص ، تهدف الدراسة إلى تحديد نسبة شيوع الإنتان الباكر لدى الولدان مع حالة تعقي سائل أمنيوسي ، تحديد عوامل الخطورة المؤهبة لتعقي السائل الأمنيوسي وإمكانية وجود ارتباط بين هذه العوامل المؤهبة وبين الإنتان الجرثومي الباكر عند الوليد . المواد والطرائق : 46 وليداً مع حالة تعقي سائل أمنيوسي تم تحري وجود الإنتان عندهم وتقسيمهم إلى مجموعتين وفقاً لوجود أو غياب عوامل الخطورة ودراسة ارتباط حدوث الإنتان مع تلك العوامل . النتائج : نسبة انتشار الإنتان عند ولدان تعقي السائل الأمنيوسي كانت 32.6% ، هناك علاقة طردية قوية بين وجود العوامل الجنينية المحتملة لحدوث التعقي وبين حدوث الإنتان الباكر عند الوليد ، علاقة متوسطة القوة بين وجود العوامل الوالدية لتعقي السائل الأمنيوسي وبين حدوث الإنتان الباكر عند الوليد . الاستنتاجات : شيوع تعقي السائل الأمنيوسي لدى حديثي الولادة ، هناك ارتباط بين وجود العوامل الجنينية والوالدية المحتملة لحدوث تعقي السائل الأمنيوسي وبين حدوث الإنتان الوليدي الباكر

A reputation-based routing protocol for wireless sensor networks

In the last decade Wireless Sensor Networks (WSNs) have been gaining recognition due to the fact that they provide inexpensive solutions for a diversity of sensitive applications. However, these networks are at high risk to many routing attacks due to the nature of their deployment as well as their device characteristics. They are usually deployed in a distributed manner, unattended for a long period of time with limited network resources such as memory, bandwidth, energy and computation power. Therefore, security plays an important role. In this paper, we propose a reputation-based routing protocol that is sufficient to thwart the routing attacks in the neighborhood for WSNs. The proposed protocol maintains neighbors reputations based on their locations and packet transmission information to select the well-behaved forwarding node to transmit the data packets through multiple hops toward the destination. Our results illustrate the enhancement of network performance in terms of packet delivery as well as a reduced amount of attack selection in the process of transmitting packet to the destination

Keberkesanan kurikulum pendidikan sains sosial di Malaysia: kajian perspektif guru siswazah dan pengetua sekolah di UPSI

Kesan globalisasi, liberalisasi dan perkembangan teknologi maklumat memerlukan penyesuaian dan penambahbaikan terhadap sistem pendidikan di peringkat pengajian tinggi demi menghasilkan modal insan yang mempunyai keupayaan pengetahuan, kemahiran dan ciri-ciri peribadi seorang pelajar yang unggul lagi holistik dari segi keilmuan itu sendiri, sahsiah peribadi atau kerohanian diri . Kajian ini bertujuan menilai keberkesanan kurikulum sains sosial di Fakulti Sains Kemanusiaan (FSK), Universiti Pendidikan Sultan Idris (UPSI) dalam melahirkan pendidik yang seiring dengan matlamat Kementerian Pendidikan Malaysia dan institusi pendidikan lain di Malaysia. Kajian ini menggunakan kaedah kualitatif, iaitu kaedah temu bual mendalam ke atas lima orang guru siswazah FSK UPSI dan lima orang majikan (pengetua). Data temu bual di analisis secara induktif dan deduktif dengan menggunakan perisian ATLAS.ti. Hasil kajian mendapati bahawa keberkesanan kurikulum di FSK, UPSI dari perspektif siswazah berada pada tahap yang memuaskan bagi tema keberkesanan kurikulum dan keberkesanan kokurikulum. Namun respons bagi tema keberkesanan kemahiran dan kemahiran kerjaya adalah kurang memuaskan dan perlu diberikan perhatian. Secara keseluruhan pihak pengetua turut mengakui keberkesanan guru sains sosial UPSI dengan penambahbaikan terhadap aspek kemahiran berfikir, etika dan nilai. Kedua-dua ini pada pandangan pengetua amat penting difahami dan dilaksanakan oleh guru dengan sebaiknya. Justeru, semakan semula kurikulum di peringkat universiti wajar mengambil kira perkara tersebut dan seterusnya menyediakan pelan tindakan bagi memantapkan kurikulum pendidikan sains sosial di UPSI
