Electrooptic soft mode response of compounds exhibiting the antiferroelectric phase

We report measurements on the electrooptic response of thin samples (~2-5 μm) of two antiferroelectric liquid crystals. All the phase transitions in these compounds can be very easily detected using this technique. We have been able to measure such an electrooptic effect for the first time in the antiferroelectric and smectic I∗ phases of a tolane compound. The response shows a relaxation at high frequencies (~10 KHz) and is at-tributed to a soft mode which produces an asymmetry in the molecular tilt in successive layers

Crptography based Lifi for Patient Privacy and Emergency Health Service Using IOT

Medical care is one such region, where WIFI is as yet not utilized as the electromagnetic waves influences patients with sicknesses like neurological problems, diseases and so forth. Accordingly, LIFI can be respected the following large thing, as it represents no gamble to patients and offers more advantages than WIFI, such as faster speeds and a larger spectrum. The only issue that hospitals have while exchanging data through it is ensuring confidentiality. The methodology proposed here leverages Secure Hash Algorithms to give maximum security as a solution to this challenge. The Secure Hash Algorithm is a bonus feature that is mostly utilised for authentication. IoT connects physical devices such as sensors and actuators to networks. The programming routines can be visualised from any location thanks to cloud storage. These algorithms can be employed in a variety of applications, including smart homes, digital technologies, and banking systems. This research presents a model that takes into account a human's heart rate, glucose level, and temperature. In the even to fan emergency, adjacent hospitals are alerted to the patient's condition, allowing them to provide timely and correct care. This will save you from having to go to the hospital. Temperature, blood pressure, heart rate, gas sensor, and fall detection are among the vital signs monitored by the system. An Arduino controller and a GSM900Amodule make up the system design. The monitored values can be supplied via mobile phones, and if an abnormal state is detected, the buzzer is activated, and the information is communicated to the concerned members via the mobile app

A global classroom? evaluating the effectiveness of global virtual collaboration as a teaching tool in management education

We evaluate the effectiveness of global virtual student collaboration projects in international management education.Over 6,000 students from nearly 80 universities in 43 countries worked in global virtual teams for 2 months as part of their international management courses.Multisource longitudinal data were collected, including student and instructor feedback, course evaluations, assessment of changes in knowledge, attitudes, and behaviors following the experiential project, and various indicators of individual and team performance.Drawing on experiential learning, social learning, and intergroup contact theories, the effectiveness of the experiential global virtual teambased approach in international management education was evaluated at the levels of reactions, learning, attitudes, behaviors, and performance.The findings show positive outcomes at each level, but also reveal challenges and limitations of using global virtual team projects for learning and education. Implications for international management education and suggestions for future research are discussed

The health care and life sciences community profile for dataset descriptions

Access to consistent, high-quality metadata is critical to finding, understanding, and reusing scientific data. However, while there are many relevant vocabularies for the annotation of a dataset, none sufficiently captures all the necessary metadata. This prevents uniform indexing and querying of dataset repositories. Towards providing a practical guide for producing a high quality description of biomedical datasets, the W3C Semantic Web for Health Care and the Life Sciences Interest Group (HCLSIG) identified Resource Description Framework (RDF) vocabularies that could be used to specify common metadata elements and their value sets. The resulting guideline covers elements of description, identification, attribution, versioning, provenance, and content summarization. This guideline reuses existing vocabularies, and is intended to meet key functional requirements including indexing, discovery, exchange, query, and retrieval of datasets, thereby enabling the publication of FAIR data. The resulting metadata profile is generic and could be used by other domains with an interest in providing machine readable descriptions of versioned datasets

Institutional distance and knowledge acquisition in international buyer–supplier relationships::the moderating role of trust

Institutional distance can generate expanded opportunities for multinational firms to facilitate learning and responsiveness. However, such distance can also create obstacles regarding knowledge transfer and integration. A theoretical puzzle concerns the mechanisms and conditions in which international buyers and suppliers can overcome institutional distance and acquire new knowledge. We develop an integrative moderated-mediation model in which institutional distance prevents parties from accessing knowledge but, when knowledge is obtained and mutual trust is developed, it promotes cross-border knowledge acquisition in international buyer-supplier exchange, particularly between international firms and firms from the Asia Pacific region. These findings indicate that firms can overcome the challenges of regulative and cognitive distance and facilitate access to knowledge and knowledge acquisition when they are able to develop and cultivate relationships of mutual trust with foreign partners. While normative distance may create learning incentives and opportunities in international buyer-supplier relationships, its impacts on knowledge accessibility and acquisition are insignificant.fi=vertaisarvioitu|en=peerReviewed

Family Business Restructuring:A Review and Research Agenda

Although business restructuring occurs frequently and it is important for the prosperity of family firms across generations, research on family firms has largely evolved separately from research on business restructuring. This is a missed opportunity, since the two domains are complementary, and understanding the context, process, content, and outcome dimensions is relevant to both research streams. We address this by examining the intersection between research on business restructuring and family firms to improve our knowledge of each area and inform future research. To achieve this goal, we review and organize research across different dimensions to create an integrative framework. Building on current research, we focus on 88 studies at the intersection of family firm and business restructuring research to develop a model that identifies research needs and suggests directions for future research

Cultural Distance and Firm Internationalization:A Meta-Analytical Review and Theoretical Implications

This paper presents the most comprehensive review and meta-analysis of the literature on cultural distance and firm internationalization to date. We analyze the effects of cultural distance on key strategic decisions throughout the entire process of internationalization. For the preinvestment stage, we examine the decisions on where to invest (location choice), how much to invest (degree of ownership), and how to organize the foreign expansion (entry and establishment mode). For the postinvestment stage, we examine the decisions of how to integrate the foreign subsidiary into the organization (transfer of practices) as well as the performance effects of cultural distance at both the subsidiary and the firm level. We find that firms are less likely to expand to culturally distant locations but if they do, they prefer greenfield investments and integrate subsidiaries more through transfer of management practices. Cultural distance does not seem to affect how much capital firms invest and whether they enter through a joint venture or full ownership. Interestingly, cultural distance has a strong negative effect on subsidiary performance but no effect on the performance of the whole multinational company. In addition, we find that the effects of cultural distance are not sensitive to time, but they are sensitive to the cultural framework used (e.g., Hofstede vs. Global Leadership and Organizational Behavior Effectiveness) and the home country of the company (developed vs. emerging market). Based on our study, we feel confident to offer some theoretical insights, recommendations for improving the validity and reliability of cultural-distance research, and ideas for future research

A Selective Complexometric Determination of Palladium

Distribution of nutrients in the Periyar river estuary

49-54Levels of phosphate, nitrate, nitrite and ammonia from 9 stations in the Cochin backwaters in an area extending from barmouth to 21 km upstream, up to an industrial belt at Eloor (Alwaye) were estimated. Inorganic phosphate showed an increasing trend towards upstream from sts 1-8 and decreased at st 9 in all months. Nitrate indicated irregular pattern of spatial and temporal variations. Interface water exhibited maximum fluctuations. Partial distribution of nitrite in the surface and bottom waters revealed a gradual reduction in the nitrite content from st 5 to st 9. High values were recorded only for interface water in most of the months at sts 5 and 6. Nitrite content at the effluent discharge point (st 8) varied from 0.8-2.67-mu-mol.l-1. Levels of ammonia increased towards upstream with low values at sts 1-4 and 9 and high values for surface water (844-mu-mol.l-1) at the effluent discharge point (st 8). Temporal variations were highly irregular. Interface water showed higher values compared to the surface and bottom water. Irregular pattern of distribution of ammonia was recorded at all stations. Early monsoon season showed uniform conditions in this section. Subsequently a build up of nutrients in the mid-reaches was suggested. The fluctuations noticed in the nutrient levels may be the after effect of intermittent discharges of effluents and variations in river flow
