        As teachers we take delight and pride in seeing our learners succeed, not just in our classes but also in their personal lives and into the future. Much of this depends on their ability to ‘see the bigger picture’. Learning is hard and to stick with it, even when there is no teacher around, requires finding reasons to put in the effort. Learners are not often asked to do this and so don’t develop the skill to question why they are doing what they are doing. It is therefore important to consider ways to give learners greater control over their learning, and to do so in such a way that prepares, supports and ultimately empowers them to become more autonomous (Reinders, 2020). In this article we will look at practical ways to help learners become aware of their own and teachers’ reasons for learning and see how this focus on personal learning aims forms an ongoing, iterative (recurring) part of the autonomous learning process.

        The Dromedary camel (Camelus dromedaries) is an important species because of its ability to produce good quality meat, milk, and fibers under harsh environmental conditions. Camels are also crucial for transportation, racing, and as draft animals in agriculture. Therefore, dromedary camels play a critical role in the economy for millions of people living in the arid part of the world. The inherent capability of camels to produce meat and milk is highly correlated with their reproductive performance. Compared with other domestic species, the reproductive efficiency in camelids is low. Although recent reproductive technologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) have been successfully applied to camelids and the birth of live offspring following these technologies has been reported; in vitro embryo production (IVP) has lagged in this species. The development of the IVP system for dromedary camels may be a useful tool for the genetic improvement of this species. IVP in farm animals includes three main steps; in vitro maturation (IVM) of an oocyte, IVF of a matured oocyte, and in vitro culture (IVC) of fertilized oocyte up to the blastocyst stage. This review aims to summarize various factors that influence oocyte quality, IVM, and in vitro embryo development in dromedary camel.

        Colibacillosis, which is caused by Escherichia coli (E. coli), is one of the most common infectious diseases affecting poultry and causes the great economic losses to poultry production worldwide. The present study investigated the presence of E. coli in broiler chickens affected by colibacillosis and reared at various locations in Tiaret Province as well as evaluated the susceptibility of isolated E. coli strains to various antimicrobial agents. A total of 110 samples collected from 55 broiler chickens representing liver (n=55) and spleen (n=55) showing lesions suspected to be colibacillosis were analyzed by conventional methods, and 33 E. coli isolates were tested on a panel of seven antimicrobial agents using the disk diffusion method. The overall isolation rates of E. coli were 60% (33/55) and 50.9% (56/110) in whole chickens and organs, respectively. There was no variation in the isolation rate between organs: 50% (28/56) for liver and 50% (28/56) for spleen. All E. coli isolates tested showed 100% resistance to Nalidixic acid and Ofloxacine, followed by 93.93%, 90.90%, and 51.51% resistance to Tetracycline, Trimethoprim-sulfamethoxazole (Co-trimoxazole), and Chloramphenicol, respectively. However, low resistance to Gentamycin was observed (12.12%), whereas all E. coli isolates were susceptible to Colistin sulfate. Multidrug resistance was observed in 96.96% (32/33) of the isolates tested. We conclude that E. coli was largely present in broiler chickens affected by colibacillosis in Tiaret Province, and multidrug-resistant E. coli isolates showed high resistance to multiple antibiotics.

        Fluctuation in the price of oil has been an international concern for decades, because oil is the primary export and main economic driver for many States. OPEC as an international organization is practicing its role in controlling oil prices and oil market under the rules and norms of international law. In 2014, the price of oil decreased tremendously in a way that shocked the international market. OPEC tried to stem the losses and prevent prices from falling even further, and tried to facilitate international law in the current crisis. World markets were further shocked when OPEC announced that it would not cut production, and that the market would be supplied by the usual average amount of oil exports. In contrast, WTO cut its global trade in an attempt to shore up prices in the international markets, since low oil prices affected international trade as well. In this article, I analyze the oil crisis that hit the world from 2014 to the early year of 2016 period, and the role of international organizations such as OPEC and WTO in facing international economic crises, as well as the role of international politics to assure the implementation of law.
