In this paper we take a close look at those strategic incentives arising in a situation where firms share the costs and profits in a multi-firm project, and bargain for their respective (precommitted) split of cost- and profit-shares. We establish that, when each firm's effort contribution to the joint undertaking is mutually observable (which is often the case in closely collaborative operations) and hence can form basis of the contingent cost- and profit-sharing scheme, it is not the gross economic efficiency but the super-/sub-additivity of the nett returns from effort that directly affects the sustainability of a profile of firms' effort contributions. The (in)efficiency result we obtain in this paper is of different nature from so-called “free riding” or “team competition” problems: the set of sustainable outcomes with bargaining over precommitted cost- and profit-shares is generally neither a superset nor a subset of the sustainable set without bargaining.

This paper reviews, summarizes and pieces together scattered information on the newly completed Chicago Riverwalk in Chicago, Illinois. It explains the design process that transformed an outmoded infrastructure and disused river banks into an attractive gathering civic space, a linear urban park and a functional transportation corridor.

Literature review.

Overall, the paper reports on one of the latest projects in Chicago that symbolizes the city's long history and earnest commitment to urban sustainability.

The paper identifies key urban sustainability lessons that are transferable to other cities.

It is the first paper that stitches together scattered information on the topic.

This paper aims to investigate the tribological behavior and online infrared spectra of three types of lubricating oils containing dinonyl diphenylamine (DNDA) antioxidant, which are mineral oil (MO), poly alpha olefin (PAO) and trimethylolpropane trioleate (TMPTO), during the friction process at high temperature (temperature rising at first and isothermal holding afterwards).

A platform of low speed four-ball tribometer equipped with a temperature controller combined with infrared spectrometer was established. MO, PAO and TMPTO base oils were mixed with 1.0 Wt.% DNDA antioxidant, coded as MO_a, PAO_a and TMPTO_a in sequence. The friction coefficient and online infrared spectra of the oils were tested during the friction process of temperature rising at first and isothermal holding afterwards, and the wear tracks of the upper balls were measured using a confocal scanning optical microscope.

The results indicated that the DNDA antioxidant was depleted to reduce the generation of alcohols and carbonyl products, and the depletion rate of DNDA followed the sequence of MO_a > PAO_a > TMPTO_a. In the temperature rising friction process, the critical transition of friction coefficient was confirmed. The addition of DNDA antioxidant reduced the temperature of the oils at the critical transition of friction coefficient, and the temperature followed the sequence of TMPTO_a > PAO_a > MO_a. After the critical transition, the friction coefficient was first increased and then declined to a steady value; the friction coefficient of MO_a increased and declined first, followed by PAO_a and TMPTO_a. In the steady stage of friction, there was no obvious effect of DNDA on the friction coefficient of the oils. Moreover, DNDA enhanced the wear properties of MO_a and PAO_a; no obvious improvement was revealed for the wear property of TMPTO_a.

The established platform of low speed four-ball tribometer combined with infrared spectrometer successfully realized online testing of the structure changes of lubricating oil during high temperature friction, which can give some reference on the oxidation and friction researches of lubricating oil.

Currently, the researches on garment development and wear comfort evaluation mainly focus on the static condition type and seldom involved dynamic condition. Therefore, the purpose of this paper is to develop cycling clothes’ patterns and evaluate their dynamic wear comfort.

First, the 3D-to-2D flattening technology was applied to develop garment patterns of a cycler’s jersey T-shirt. Then, 3D animation technology was used to simulate the scene of cycling. Next, a novel pressure-measuring method was proposed to measure static and dynamic clothing pressures in a virtual environment. Finally, the collected data were used for evaluating wear comfort.

Compared to static conditions, the dynamic wear comfort noticeably improved at the front neck, side neck, upper front chest, around back neck point and front shoulder, and the front neck. Compared to static conditions, the dynamic wear comfort visibly deteriorates at the back neck, below chest, outseam, back except around back neck point and around scapula, and the around scapula area. The dynamic pressure at back neck, below front chest and shoulder fluctuate wildly throughout the whole cycling. On the contrary, the dynamic pressure at the front neck, side neck, front upper chest and at the back cause it to tend to stability during cycling.

The 3D virtual-reality technology was applied to simulate cycling. And a novel method was proposed to measure numerical clothing pressures for evaluating the dynamic wear comfort. The proposed method can not only quantitatively evaluate the wear comfort of cycling clothes and optimize cycling clothes’ patterns, but also can be applied to other tight garment types.

The aim is to identify Henri Fayol's motivations as an accomplished business manager to publish his management theory at the age of 75.

The authors retrace Henri Fayol's private life using primary sources from various French public archives including civil registry records, military and diplomatic archives, schooling records, publications from learned associations and inheritance declarations. They then use a psychological theory, namely equity theory, to interpret this new information about Fayol's private life and construct an explanation of his efforts to theorise his management experience.

Henri Fayol's schooling and his father's military career respectively influenced his perception of mathematics teaching in management training and the functioning of the army. His motivation to found a science of management was not financial but instead most probably a response to the obstacles his father encountered during his career.

It is rarely known what motivates a manager to collaborate with specialists in management science. This research into Henri Fayol's motivations can be replicated for other managers.

The paper dentifies one major practical implication for managers who wish to contribute to management theory as Fayol did. Before they begin such an undertaking, it is important for them to reflect upon their motivations. Their motivations as managers, based on financial and business success are insufficient. Deeper motivations are needed, that are anchored in their own personal history to drive the considerable intellectual investment that is necessary for them to be successful contributors.

The results encourage managers to contribute to building and improving management science. They can theorize their experiences in dealing with the management of contemporary issues such as sustainable development and social responsibility. They must do so as Fayol did: using scientific method and strongly motivated by personal beliefs.

The research question is original: “What motivated Fayol to build his management doctrine?”. Scholars rarely ask why individuals decide to build and organize knowledge. This question is relevant for managers today as they too can bring original contributions to management thought. The paper reports previously unpublished details about Fayol's life to answer the research question, and in doing so completes and corrects the works of Sasaki Tsuneo and Henri Verney.

Batik is a craft in the creative industry, which is the identity of the Indonesian nation. One of the main batik tourism areas in Indonesia is Trusmi, and women entrepreneurs have a strategic role in developing the batik craft industry in the region. The batik industry faced various challenges during coronavirus disease 2019 (COVID-19). Therefore, this study aims to explore the impact and identify strategic options during the COVID-19 period on batik businesses owned by women entrepreneurs in the Trusmi area.

This study uses a qualitative case study method by interviewing ten batik women entrepreneurs in the Trusmi area.

This study elaborates findings about the impact of COVID-19, the technology role, collaboration, the government role and strategic options.

This study provides academic and practical implications, which are discussed further about the role of the craft industry in dealing with economic and social turmoil.
