The purpose of this paper is to examine whether analysts’ cash flow forecasts improve the profitability of their stock recommendations and whether the positive effect of cash flow forecasts on analysts’ stock recommendation performance varies with firms’ earnings quality.

To test the authors’ predictions, they identify a sample of 161,673 stock recommendations with contemporaneous earnings forecasts and/or cash flow forecasts and regress market-adjusted stock returns on a binary variable that proxies for the issuance of cash flow forecasts while controlling for contemporaneous earnings forecast accuracy, earnings quality, analysts’ forecast experience and capability and certain firm characteristics. The authors’ test results are robust to alternative measures of recommendation profitability, earnings quality and the use of recommendation revisions instead of recommendation levels.

The authors find that when analysts issue cash flow forecasts concurrently with earnings forecasts, their stock recommendations lead to higher profitability than when they only issue earnings forecasts, after controlling for analysts’ forecast capability. Moreover, the authors document that the contemporaneous positive relationship between cash flow forecasts and recommendations profitability is stronger for firms with low earnings quality than for firms with high earnings quality. The findings suggest that cash flow forecasts issued by analysts in response to market demand likely play a more important role in firm valuation than cash flow forecasts issued by analysts mainly because of supply-side considerations.

Future research could build on these findings to conduct further investigation on the alternative incentives for analysts’ forecasts of sales growth and long-term growth rates.

These findings may also help investors to better assess the quality of analysts’ research outputs and to identify superior stock recommendations.

This study provides insight into the role of cash flow forecasts in firm valuation and adds fresh evidence to the debate on the usefulness of cash flow forecasts. It extends the stream of research on the characteristics of analyst forecasts and increases our knowledge about the role of analysts in the financial market.

In this work, minimum energy based interpolation has been done for an optimal well path and effects of energy and fitting coefficients have been studied. An optimal well path also maintains the given radius of curvature and satisfies drilling requirements. Interactive incremental design concept has been used in this work which, controls length and other geometric properties of well path. In the first part of the research, whole well segment has been taken for optimization. Geometric constraints are put to satisfy the drilling requirements. In the second part of the research only the curved portion of well segment has been taken for optimization. Geometric perspective of the well has been considered in this formulation.

Enterprise activities are often harmful to the natural environment or societal fabric, yet approaches that are environmentally constructive or socially responsible can be challenging and may not be rewarded by the marketplace. Enterprises that are not sufficiently financially successful perish. The purpose of this paper is to present a model and methodology referred to as sustainable enterprise excellence, resilience and robustness (SEER2) that provides enterprises with a means of balancing financial, social, and environmental considerations. These considerations form the classic elements of the triple bottom line and are central formation of enterprise responses to climate change and social strain.

A model referred to as the Springboard to SEER2 is introduced. SEER2 explicitly considers societal and environmental performance and impacts that are driven by strategy and implemented through processes. As such criteria associated with the Springboard that address strategy, processes, performance, and impact are also introduced.

Humanity is at individual, enterprise, and societal levels partially or wholly responsible for many critical and time-sensitive social and environmental challenges. Due to their vast collective resource consumption and resource base, enterprises should also contribute to solving such challenges. The presented Springboard to SEER2 model and associated criteria provide a rigorous, yet defined path for enterprises that have the determination to confront such challenges.

This is among the first explorations of enterprise self-assessment in general and SEER2 in particular that explicitly consider strategies, processes and activities important to mitigation of climate change and social strain.

This research aims to focus on developing a customized support surface using additive manufacturing (AM) for effective pressure relief for patients who are in bed or wheelchair suffering from pressure ulcers (PU).

A novel customized support surface is developed using AM technology incorporated with magnetic levitation and ball and socket mechanisms. Magnetic levitation provides cushioning effect for the developed cushion to users who are sitting in a wheelchair and increases the rate of healing. The ball and socket mechanism provides the user body's self-adaptive mechanism and reduces shear and friction forces between the surfaces of the additive manufactured cushion and the human buttocks.

From the results of ISO 16480-6 biomechanical standardized tests, the additive manufactured support surface performed better than, or on par with, the most widely available commercial cushions. It is evident that the developed cushion’s peak pressure values are lower when compared with other cushions. The overall efficiency of the developed cushion was qualitatively reported; 67% of people felt it was excellent and 22% of people responded as good and 11% were satisfactory. Henceforth, the overall effectiveness of the developed support surface provides a better experience to the end-user in the view of PU reduction.

A developed additive manufactured customized support surface will be an alternative approach for the reduction of PU, and it overcomes the drawbacks faced by the currently available cushions.

The purpose of this study is to conceptualize the paradigm of meaningful innovation (MI) by exploring the theoretical basis, identifying its core concepts and key processes, and supporting it with evidence from leading world-class enterprises.

Based on a systemic literature review on the evolution of innovation paradigms, this study builds a conceptual framework to explicate the core concepts and process of MI. Moreover, a horizontal embedded case study of GREE electric appliances is conducted to further enrich, refine and support the proposed framework.

The main finding of this study is that MI could be regarded as a process of integrating innovation elements (resources, capabilities, systems, etc.) with internal and external innovation meaning to obtain outcomes with both economic value and social significance. As a “long-termism” paradigm with meaning identification and conversion as its core, MI is driven by the collaboration of “deductive mechanism” and “reflective mechanism.”

Based on the previous studies concerning innovation paradigms on the internal and external meaning, this paper proposes an integrated framework of MI. In this framework, enterprises can consider internal and external meanings through deductive and reflective mechanisms, to better coordinate resources, capabilities, institutions, markets and other factors to achieve higher innovation performance.

This paper studies how Chinese consumers respond to foreign goods in the post‐WTO era. Specifically, it examines brand sensitivity as a mediator and product cues as moderator of purchase intention. Additionally, it examines consumer preferences for different products and consumption plans for the subsequent five years. The survey sample is drawn from a population of foreign product users from 34 cities in 18 provinces in China. Results provide evidence that brand sensitivity mediates the relationship between consumer ethnocentrism and purchase intention; product cues moderate the effect of ethnocentrism on purchase intention. As the first study to link consumer ethnocentrism directly to brand sensitivity and purchase intention, this research provides some managerial implications. Global marketers can offset the negative effect of ethnocentrism by emphasizing brand image of its products, taking advantage of specific product cues, or by providing more comprehensive after‐sale service to reduce the perceived risk of purchasing imports. Also, price is still a hurdle that prevents Chinese consumers from mass consumption of foreign products. Global firms should not overestimate the purchasing power of Chinese consumers. This study represents a “snapshot” of Chinese consumers’ decision making at a time when their economic system is undergoing rapid change.

This paper delineates a literature review on fire-induced progressive collapse on structures and the effect of high temperature on structures and elements. After the occurrences of fire in the World Trade Center in the USA, the researchers started concentrating on the progressive collapse that happens due to high temperature. Currently, most of the researchers are working on fire-induced progressive collapse on structures using high-temperature behavior on materials which are used for construction. The researchers have been doing an intensive study to find a better strategy to prevent the building from structural fire damage or collapse with available codes and guidelines throughout the world. This paper aims to provide a better understanding and analytical solutions on the basis of the recent works done by researchers in fire-induced progressive collapse and methods adopted to find the collapse mechanism.

This paper is written by studying different literature papers of 109 related to progressive collapse on structures and fire-induced progressive collapse.

The behavior of structures due to high temperature and collapse conditions due to fire in different scenarios is identified.

This paper fulfills an identified need to study how the structure can withstand high-temperature conditions in our day-to-day lives.
