“…Random assignment is the process of assigning individuals at random to different groups in an experiment (Webster and Sell, 2012). Experiments that involve random assignments are considered to provide the most rigorous evidence that a specific intervention produces a certain outcome.…”

“…Experiments that involve random assignments are considered to provide the most rigorous evidence that a specific intervention produces a certain outcome. Webster and Sell (2012) argues that providing random assignment of participants of various groups is the quality that differentiates true experiments from less rigorous quasiexperiments. The main purpose of random assignments is to make sure that different assignments provided to different groups in experimental research are similar to the extent that it may impact the outcome of the experiment (Slavin, 2007).…”

“…Experiments can powerfully test hypotheses and focus evidence about causal relationships. An experiment's purpose is to satisfy the three conditions for causality: first, the sequence in which the independent variable precedes the dependent variable, second to identify the evidence of an association, and finally ruling out alternative causes (Webster and Sell, 2012).…”

Contracts are important for employment in any organization. In order to reach a common point of agreement, both employer and employees’ negotiate important aspects of the contract. Objective of this study are: to find out sources of conflict during employment contracts and to eradicate or minimize the conflict by means of negotiations. In current study, negotiating contracts of employment is investigated through experimental research methodology. Data about negotiating employment contracts are collected through structured observations from Pre-test and Post-test experimental groups. Analysis of the collected data is done through one-sample T-test the results of which and the P-value showed that important concepts are included in structured observations about negotiating employment contracts. It is concluded that pay is an important factor in negotiating employment contracts. It is recommended that such negotiations may be used in other types of contracts like business contracts, and other methods can be used in such studies.

“…a calving interval of 12 months. Ideally this is achieved with few inseminations per conception and with a low number of cows being culled for infertility (Ball and Peters, 2004b;Webster, 2020). A dairy bull optimally produces a consistently high amount of healthy sperm, and has the physical fitness and libido to achieve intromission and deposit semen in the vagina (Penny, 2009).…”

Good cattle reproductive performance is essential for livestock productivity. Farmers are highly dependent on the success of productive outputs to support their livelihoods. In low- and middle-income countries (LMICs), however, optimal reproduction of cows and bulls is comparatively less well defined, with information on key reproductive parameters and reproductive management often not available. The aim of this study was to collate and synthesise the recent published evidence on cattle reproductive performance in selected sub-Saharan countries.Systematic mapping methodology was used, with searches conducted for both cow and bull reproductive performance in Eritrea, Ethiopia, Kenya, Nigeria, Somalia, South Sudan, Sudan, Tanzania and Uganda, for the period 2012-2022, in English language. Search returns were screened for relevance at title and abstract, and full-text levels, based on the research question criteria.A substantial number of studies were identified for cows (n = 133), but only very few for bulls (n = 11). A large proportion of reported studies have been conducted in Ethiopia, with relatively few from the other countries, and most studies published between 2014 and 2016, and in 2021. Certain reproductive parameters received more attention than others; calving interval was reported in 86 studies, while culling due to infertility was reported in eight studies.The study highlights where research is being conducted in this area, and importantly where there is a gap, in particular on bull reproductive performance. While there were a range of values reported for cow reproductive parameters, the values were reasonable, indicating that it is possible to have good reproductive performance in LMICs. The synthesis of studies in the map should help to inform farmers and their advisors, at farm and national levels.
