Although we often are tasked with learning pieces of information that are related in some way in educational settings, the learning conditions that promote learning of and connections across related information are still poorly understood. In this thesis, I asked: Which instruction methods promote learning of and connections across (integration of) related information? In the two experiments in this thesis, participants were presented related information in two different formats, and we assessed their memory for related information, in addition to how well they could integrate related information to derive new knowledge. The two presentation formats incorporated the same number of exposures of related information, but the sequence with which information was presented was manipulated: In one presentation format (blocked) participants strongly learn one set of information, before being confronted with a related set of information, whereas participants learn related information in parallel in the other (interleaved). In Experiment 1, we found that blocked presentation enhanced both memory for and integration of related information. However, given potential effects of testing order on our results, we more closely examined memory for related information in Experiment 2. In Experiment 2, we no longer found a difference in overall memory for related information between the two presentation formats. In fact, we found evidence that presence of shared information enhanced learning of related information after interleaved presentation only. Regardless, the results of both experiments demonstrated that manipulating just the sequence with which information is presented, without increasing the number of exposures, can enhance learning, an impactful finding in an era of increased pressures to maximize instructional time.

Introduction: This study examined effects of two journalistic practices in reporting conflicting scientific evidence, hedging and presentation format, on scientists’ and journalists’ credibility and issue uncertainty. Methods: An online experiment was conducted using students from a western U.S. university. Hedging was manipulated as reporting methodological limitations versus not reporting the limitations in news articles covering the conflict. Presentation format was manipulated as using a single news article to report both sides of the conflict versus using double articles with one side of the conflict in one article and the other side in the other article. Results: The study found that perceived issue uncertainty was higher in hedged news articles than that in non-hedged articles; presentation format did not affect people’s perceived issue uncertainty. For scientists’ credibility (both competence and trustworthiness), this study found that it was lower in the single-article format than that in the double-article format; for journalists’ credibility, this study found that journalists’ trustworthiness in the two formats did not vary, but their competence was lower in the double-article format than that in the single-article format. Conclusion: This study contributes to the field of science and health communication by examining effects of presentation format used in communicating conflicting health-related scientific evidence and by examining effects of communicating scientific limitations in a context where conflicting evidence exists. Keywords: conflicting scientific evidence, hedging, presentation format, scientists’ credibility, journalists’ credibility

We could characterize today's business world with numerous attributes, namely: dynamism, turbulence, complexity, etc. But if we had to give a brief definition of the specific challenges business management will have to face in the next century, the best choice would surely be talking about ‘global market’ and ‘knowledge management’. These are the two concepts we have tried to combine in this paper, trying to emphasize the starring role human resources management must play in this scenario. The globalization of economy is already a reality firms currently have to face, but what is the role of knowledge, or of those who own that knowledge (human resources) within a global framework? If we analyze the human capital in an firm according to the resource-based view of the firm, we can consider knowledge as an intangible resource on which organizations can build up their competitive advantages and keep them with the pass of time; and knowledge management can be seen as a strategic capability as long as the practices being used encourage the development and accumulation of a knowledge stock that will allow the firm to design an operating procedure which no other competitors can imitate. It will have to be the human resources management's task to generate a leverage among individual competences through the construction of an Organizational Learning Scheme. Organizational Learning can be understood as a collective phenomenon in which new knowledge is acquired by the members of an organization with the aim of settling, as well as developing, the core competences in the firm, taking individual learning as the basic starting point. There are various ways an firm can follow when it comes to learning, two of which stand out from the others: through accumulated experience or through experimentation, both of which are compatible with the concept of globalization, or with the decision made by an firm to start working overseas, that is, to become internationalized. An firm can choose to operate in a global market in order to achieve a higher income through the exploitation of its know-how, its brand name, or the management capabilities of the domestic firm in different countries. Thus, if we consider human knowledge as a key strategic factor on which competitive advantages can be built, we could justify the value of human resources in firms which start operating on an international scale through the competences that these human resources can develop, among which we can highlight the role played by the competences of the human capital from the parent company. In this case, the organization would be resorting to learning through accumulated experience. But we cannot forget that if the firm exploits exclusively its core competences, without trying to accumulate new distinctive competences, it will suffer, in the long run, a competitive disadvantage, insofar as it will have to face the competition of firms highly motivated by the learning that their resource basis will have developed, which will alter the competition terms. In this sense, we could consider the firm's internationalization as being, apart from a procedure to strengthen and exploit the firm's strategic competences, as a way of revitalizing or renewing them, reconfigurating the ‘domestic knowledge’ by means of other knowledge, through addition and combination, a new knowledge arising this way. On the other hand, it is in turn not an easy task to exploit and to achieve a return on domestic knowledge (which normally has an implicit nature) in other countries, and it is even more difficult to follow a conversion cycle so that new knowledge can be incorporated. Thus, we can highlight, as possible ways of transferring basic knowledge, imitation through the practical exercise of the head firm's operating procedures (using an ethnocentric approach), carrying out an exchange of experiences and, above all, two of the most commonly used actions in firms having to face internationalization processes, namely, the transfer of employees and the use of expatriates. The way in which that knowledge is later complemented and combined with that of the other entities, will depend on the learning rate reached in each specific unit, although we must point out that one of the critical factors when it comes to the achievement of an Organizational Learning Scheme is the consolidation of a cultural framework which encourages permanent improvement and which is specially characterized by the open attitude towards experimentation, the stimulus to take chances and the will to face failures or mistakes and to try and learn from them. In short, the study of Organizational Learning in a global market is one of the fields to be developed in human resources management, for two main reasons; on the one hand, the globalization of economy is a phenomenon which has an influence on the firms' success and, on the other hand, because competitive advantage currently lies in knowledge, and this can only have one replacement, more knowledge.

A young science serves its purpose if it leads not only to new knowledge, but to new insights and concepts. This article opens with examples to illustrate some former thinking that the introduction of pharmacogenetic has overcome. Pharmacogenetic case histories from discovery to the present illustrate the interlocking of observations, technical advances, and changing concepts. There are striking biological similarities between pharmacogenetics and those inborn factors that cause resistance to infectious disease: Both represent person-to-person variations that may help the survival of populations, one when facing massive toxic exposures, the other when facing plagues and epidemics. Thus pharmacogenetics represents a biologically necessary variability of the defenses against chemical intruders, and this includes drugs. While this variability is desirable, drug toxicity occurring on the basis of this variability must be avoided. The most successful defendants against toxicity due to polymorphic (ie, high incidence) variants should be the designers of new drugs. The only defender concerned with rare variants can be the attentive clinician.

AbstractIn this study, we investigated whether the use of smartphone games while reading a text reduces learning performance or reading speed. We also examined whether this is affected by push notifications. Ninety-three students were randomly assigned to three learning conditions. In the gaming group (G), participants played a game app for 20 s at 2-min intervals while reading. In one subgroup, the game app sent push notifications (GN+); in the other subgroup, no notifications (GN−) were sent. In the control group (C), participants did not play a game. After the reading, participants took a multiple-choice quiz. We compared quiz scores and reading times of the groups (G) and (C) and within the gaming group (GN+, GN−) and observed no differences. Since the statistical non-significance of these tests does not entail the absence of an effect, we conducted equivalence tests, which did not demonstrate equivalence either. The experiment ensured high internal validity, yet remained inconclusive. Reasons for the similarity of performance in all groups could be non-specific exercise effects (all participants owned a smartphone), low similarity between the tasks, low variance of participants’ ability and motivation (high achieving, low ADHD scores) or low game complexity. Future research should address these questions.

<p>Online learning has been used in the literature to cover diverse learning contexts ranging from blended learning, distance learning, virtual learning and web-enhanced learning. Many aspects of online learning have become the focuses of research and teacher roles are one of them. The present study, therefore, intends to examine how 153 university students perceived the roles of their teachers in online learning of a blended English course by using a 27-item and 5-Likert-scale questionnaire (the STRI). Results of statistical analyses showed that the Cronbach’s Alpha value of the entire questionnaire was .955 and those of the three sub-roles were all above .891, indicating that both the questionnaire and the three factors of sub-roles were reliable and valid. Further analyses revealed that the three sub-roles of teachers, i.e., the cognitive role, the affective role and the managerial role, were significantly different from each other. Among them, the means of the managerial role was significantly higher than that of the cognitive role while the means of the affective role was the lowest. Results of descriptive statistics also revealed that keeping a record of students’ learning in the managerial role was quite notable for students. The findings suggest that the roles of teachers in online learning as a whole were reduced. However, the managerial role was more notable than the other two roles and the affective role was the least impactful in the online learning context in this study. The researcher believes that these findings may offer some insights to classroom implications and provide the basis for future studies of comparing teacher roles across different educational contexts.</p>

The study was motivated by the need to harness technological advancement to enhance agricultural production in Osun State. The study assessed the utilization of Information and Communication Technologies (ICTs) tools for sharing of agricultural related information in Osun State, Nigeria. The study illustrated the socio economic characteristics of the Respondent, identified the available ICT tools for sharing of various agricultural related information, identified agricultural related information shared through various available ICT tools, measured the frequency of utilization of the identified ICT tools and assessed the severity of challenges encountered by Respondent in the utilization of ICT tools in the study area. Sixty percent of Extension Agents in each of the three zones in the study area were sampled. The data collected were examined using descriptive statistics tools while regression analysis was used to test the significant relationship between the socio-economic characteristics of Respondents and their frequency of utilization of ICT Tools for sharing of agricultural related information in the study areas. The analysis of the data was carried out with the use of SPSS version 22. The findings revealed that the average age of Respondents was 39 years; more than half of the respondent (67.1%) were male; most (81.4%) of the respondent were married; majority (68.6%) of the respondent were Christian; about (70%) of the respondent had tertiary education. The mean household size was 5 members per household; majority of the respondents belonged to one association or the other and they access the internet with their own data plan. Radio (wms 2.7) was ranked first as most available ICT tools for sharing information in the study area. Furthermore, information on availability and sources of farm inputs (wms2.3) was ranked most shared information while information on storage facilities (wms1.0) was ranked the least shared information by the Respondents. Also, the initial cost of procurement of ICT gadgets, cost of maintenance, risk of theft of gadget, and fluctuating power supply were the major challenges encountered with the use of various ICT tools. Regression analysis identified a significant relationship between selected socio-economic characteristics of the Respondents and frequency of Utilization of ICT Tools for sharing Agriculture related information. The study recommended use of Radio as medium through which agricultural related information should be shared bearing in mind its ease of access, little cost of procurement and maintenance, extent of reach and frequency of usage among the respondents. Provision of access to internet facility was recommended in order to afford respondents a limitless right to use information on the World Wide Web. Finally, alternative source of power to enable respondents recharge their ICT gadgets was recommended to make up for unreliable electricity supply.

Individual differences in resource availability, and the patterns of cognitive abilities they contribute to, are important to:• explaining variation between learners in the effectiveness of second language (L2) instructional treatments;• describing differences in implicit, incidental and explicit L2 learning processes; and• explaining child-adult differences in acquisition processes, and therefore to any general theory of second language acquisition (SLA).In this article I describe a framework for research into the effects of cognitive abilities on SLA which is based on four interlocking hypotheses. These hypotheses are drawn from research in psychology, education and SLA and, where possible, I present evidence to support each of them. The hypotheses are:1) the Aptitude Complex Hypothesis;2) the Ability Differentiation Hypothesis;3) the Fundamental Difference Hypothesis; and4) the Fundamental Similarity Hypothesis.The hypotheses, and the relationships between them, define an Aptitude Complex/Ability Differentiation framework for further examining the influence of individual differences in cognitive abilities on SLA, and for developing a theoretically motivated measure of language learning aptitude. I argue that such research should adopt the interactionist approach described by Snow (1994) to identifying individual difference/learning condition interactions at a number of levels. I illustrate some of these interactions.

Being complex systematically, Knowledge Management (KM) has always been challenging in the healthcare industry (HCI) of developing countries like Pakistan due to gap in acquiring and implementing KM processes. Despite the fact that extensive data and related information is available, the Pakistani HCI has been facing a major challenge due to the absence of a sound and solid KM process framework. Hence, the existing healthcare information systems in Pakistan lack the ability to control and cater the diversified nature of new knowledge creation and innovation. Consequentially, it results in inefficient and ineffective organization of knowledge along with inability to properly utilize important resources that are used for decision making activities. In this study, the researchers present and suggest an integrated and inter-operable KM process framework that helps to streamline and integrate a KM process in a phased comportment that identifies, defines, analyzes, collects and manages knowledge along with its innovation, dissemination, sharing and storage in an appropriate way.
