How supervisors can support employees' needs and motivation? an experimental study based on SDT.

Supervisors and managers have an increasingly significant role in employees' motivation. The applied framework in this field research was the Self-Determination Theory (SDT). In this way, it was assessed that whether supervisors can be trained in order to support employees' basic psychological needs including autonomy, relatedness, and competence. As a result, their need satisfaction and autonomous motivation were promoted, at the same time, the controlled motivation and amotivation were reduced. The training was provided to 15 supervisors then employees' need satisfaction, amotivation, controlled motivation, and autonomous motivation were investigated, pre- and post-intrvention. Performing a multilevel regression analysis revealed that employees in the intervention group showed an increment in autonomous motivation and need satisfaction, as well as a significant reduction in amotivation than those of the control group. Furthermore, increasing autonomous motivation and decreasing amotivation were moderated via increasing need satisfaction. An added value has been provided for the mentioned theory on need satisfaction by the current study. It was also indicated that a relatively brief intervention for supervisors may affect creating employees need support, and autonomous motivation increment, and amotivation reduction.

Medical educators' beliefs about learning goals, teaching, and assessment in the context of curriculum changes: a qualitative study conducted at an Iranian medical school.

BACKGROUND: Achieving changing needs, advancing knowledge, and innovations in higher education require the constant changes of medical school curricula and successfully applying the new reforms requires some modifications in the medical educators' core beliefs. The purpose of this study was to describe the medical educators' beliefs about the alignment of the learning goals with teaching and assessment processes in the context of the curriculum changes. METHOD: A qualitative method was used to study the medical educators' beliefs through selecting the faculty participants via a purposeful sampling strategy. The study was conducted at a Medical School in Iran. For the individual interviews, we invited both the professors of the basic sciences and the clinical professors who had thought medical students for at least 5 years. Ten educators were interviewed. RESULT: The results of the research showed that, in the professors' viewpoints, the development of competencies in the students has been abandoned and this is due to the priority of treatment to education in the clinical courses and the limited learning experiences. Moreover, the gap between the content and the context and the attendance of the students in the hospitals instead of the clinics to pass their internship courses has reduced the provision of authentic learning experiences. These conditions have affected the quality of education negatively. The non-systematic assessment has also worsened the situation. CONCLUSION: Despite the changes in the curriculum, the compartmentalization of the curriculum and the structure of the medical education have caused the professors' beliefs to be in line with the past perspectives. Some modifications in the structure of the curriculum seem to be necessary.

Growth performance and carcass characteristics of finishing male lambs fed barberry pomace-containing diets.

Barberry (Berberis vulgaris) fruits contain bioactive compounds with antimicrobial, antioxidant and hepatoprotective effects. The inclusion of barberry pomace (BP) in finishing diets could potentially enhance growth performance and carcass characteristics of sheep. To test this hypothesis, 21 male Balouchi lambs (24.5 ± 4 kg initial live weight; 5 ± 0.6 months of age) were randomly assigned to three BP-containing experimental diets to determine their effects on feed intake, live weight gain and carcass characteristics. The experimental diets were formulated to meet nutrient requirements for a targeted daily weight gain of 200 g as follows: (1) control diet (BP0), (2) control diet in which 7.5% of alfalfa hay and wheat straw were replaced with BP (BP75), (3) control diet in which 15% of alfalfa hay and wheat straw were replaced with BP (BP150). Lambs were fed the experimental diets for 75 days during which feed intake and live weight changes were recorded. At the end of the feeding period, lambs were fasted for 16 h, weighed and then slaughtered in order to determine carcass characteristics. Experimental diets had no effect on feed intake and growth performance of lambs. Similarly, diets had no effect (p > 0.05) on weight of carcass, commercial cuts (neck, shoulder, loin, leg, fat-tail, brisket, flank) and non-carcass components (head, skin, feet, lung and trachea, heart, liver, spleen, gastro-intestinal, kidney, bladder and testicles) but linearly increased (p < 0.05) warm and cold dressing percentage as well as heart weight. These results do not support the hypothesis that feeding BP-containing diets enhances growth performance and carcass characteristics of male Balouchi lambs. However, inclusion of BP had no negative effects on animal performance and carcass characteristics.
