Wireless sensor networks (WSNs) are periodically collecting data through randomly dispersed sensors (motes), which typically consume high energy in radio communication that mainly leans on data transmission within the network. Furthermore, dissemination mode in WSN usually produces noisy values, incorrect measurements or missing information that affect the behaviour of WSN. In this article, a Distributed Data Predictive Model (DDPM) was proposed to extend the network lifetime by decreasing the consumption in the energy of sensor nodes. It was built upon a distributive clustering model for predicting dissemination-faults in WSN. The proposed model was developed using Recursive least squares (RLS) adaptive filter integrated with a Finite Impulse Response (FIR) filter, for removing unwanted reflections and noise accompanying of the transferred signals among the sensors, aiming to minimize the size of transferred data for providing energy efficient. The experimental results demonstrated that DDPM reduced the rate of data transmission to ∼20%. Also, it decreased the energy consumption to 95% throughout the dataset sample and upgraded the performance of the sensory network by about 19.5%. Thus, it prolonged the lifetime of the network.

Collective entrepreneurship is the synergism that emerges from a collective and that propels it beyond the current state by seizing opportunities without regard to resources under its control (Stevenson and Jarrillo 1990). This study provides a conceptual model of collective entrepreneurship and its relationship with leadership and team dynamics in the context of a small family business. It proposes two types of prerequisites for collective entrepreneurship: attitudinal and behavioral. The attitudinal prerequisite is family business members’ commitment to the family business. The behavioral prerequisite includes collaboration and task conflict among family business members. Further, the article argues that leadership behaviors directly affect the attitudinal and behavioral prerequisites, and indirectly affect collective entrepreneurship. Specifically, relations- oriented and participative leadership have positive, indirect effects on collective entrepreneurship. Task-oriented leadership has both positive and negative, indirect effects on collective entrepreneurship. An empirical study of 271 small family businesses in the United States confirmed most of the hypotheses.

The purpose of this paper is to develop a highly miniaturized wireless inertial sensor system based on a novel 3D packaging technique using a flexible printed circuit (FPC). The device is very suitable for wearable applications in which small size and lightweight are required such as body area network, medical, sports and entertainment applications.

Modern wireless inertial measurement units are typically implemented on a rigid 2D printed circuit board (PCB). The design concept presented here is based around the use of a novel planar, six‐faceted, crucifix or cross‐shaped FPC instead of a rigid PCB. A number of specific functional blocks (such as microelectromechanical systems gyroscope and accelerometer sensors, microcontroller (MCU), radio transceiver, antenna, etc.) are first assigned to each of the six faces which are each 1 cm² in area. The FPC cross is then developed into a 1 cm³, 3D configuration by folding the cross at each of five bend planes. The result is a low‐volume and lightweight, 1 cm³ wireless inertial sensor that can sense and send motion sensed data wirelessly to a base station. The wireless sensor device has been designed for low power operation both at the hardware and software levels. At the base station side, a radio receiver is connected to another MCU unit, which sends received data to a personal computer (PC) and graphical user interface. The industrial, scientific and medical band (2.45 GHz) is used to achieve half duplex communication between the two sides.

A complete wireless sensor system has been realized in a 3D cube form factor using an FPC. The packaging technique employed during the work is shown to be efficient in fabricating the final cubic system and resulted in a significant saving in the final size and weight of the system. A number of design issues are identified regarding the use of FPC for implementing the 3D structure and the chosen solutions are shown to be successful in dealing with these issues.

Currently, a limitation of the system is the need for an external battery to power the sensor system. A second phase of development would be required to investigate the possibility of the integration of a battery and charging system within the cube structure. In addition, the use of flexible substrate imposes a number of restrictions in terms of the ease of manufacturability of the final system due to the requirement of the required folding step.

The small size and weight of the developed system is found to be extremely useful in different deployments. It would be useful to further explore the system performance in different application scenarios such as wearable motion tracking applications. In terms of manufacturability, component placement needs to be carefully considered, ensuring that there is sufficient distance between the components, bend planes and board edges and this leads to a slightly reduced usable area on the printed circuit.

This paper provides a novel and useful method for realizing a wireless inertial sensor system in a 3D package. The value of the chosen approach is that a significant reduction in the required system volume is achieved. In particular, a 78.5 per cent saving in volume is obtained in decreasing the module size from a 25 to a 15 mm³ size.

Guided by feminist perspectives, we critique existing approaches to the study of womenʼs entrepreneurship on epistemological grounds and suggest that the entrepreneurship field needs to recognize gendered assumptions in theorizing. Deploying a feminist framework, we suggest that understanding the “gender gap” in entrepreneurship requires focus on institutional and structural barriers women entrepreneurs face. Existing studies of women entrepreneurs often compare women with men without considering how gender and gender relations impact the very concepts and ideas of entrepreneurship. We propose, therefore, a conceptualization of entrepreneurship that illuminates gender bias and calls attention to the interrelated individual, institutional, and structural barriers in the entrepreneurial process that arrive out of societal and cultural gender norms. Through praxis or engaged practice, we redirect scholarship in the entrepreneurship field, while proposing ways that can promote gender equality in entrepreneurial activities. In all, our gender integrative conceptualization of entrepreneurship contributes to the entrepreneurship field by recognizing and addressing a more expansive realm of influential factors within the entrepreneurial ecosystem that have previously been researched separately.

This study comprehensively depicts the state of the art on sustainability research in the meat supply chain to advance the debate on challenges and issues associated with developing sustainable supply chain management practices.

The authors conducted a systematic literature review of 333 articles published in peer-reviewed journals and organized the extant literature into five areas of supply chain management practices: strategic orientation, continuity, collaboration, risk management, and proactivity.

Since 2016, the meat supply chain has received increasing scholarly attention. The literature shows the diffusion of highly heterogeneous sustainability practices related to multiple management areas and levels of analysis (institutional, industry, firm). The need for integrated, multilevel initiatives involving different stakeholders becomes increasingly crucial to the transition towards more sustainable meat supply chains.

This study highlights the importance of regulatory and stakeholder pressures in the sustainability transition. Beyond setting regulatory requirements, policymakers may facilitate the establishment of collaborations within the meat supply chain and foster the development of support services that help firms to integrate sustainability in their business models. The review also alerts entrepreneurs and managers to the benefits from cooperating with their supply chain partners to navigate the industry transition and thus more effectively respond to the demands of stakeholders and to the increasing customers’ awareness of sustainability issues.

This study is the first to systematize the corpus of knowledge on the sustainability of the meat supply chain by adopting a comprehensive approach to analyze relevant management and agriculture literature.

Studies of the first year of infant psychomotor development in cases of maternal postpartum depression are lacking. The mother and baby unit (MBU) is a healthcare system available to infants and their mothers during the postpartum period in a psychiatric hospital, which provides support and preserves the parent's role in the child's daily care. The aim of the paper is to describe the developmental profile of babies of mothers with severe postpartum depression treated in an MBU through the developmental quotients. Using the Brunet-Lézine scale, we studied six-month-old infants whose mothers were hospitalized. The study population consisted of 15 infants. The mean global developmental quotient score was 96.7. A developmental quotient lower than 80 was not observed for any of the children. We found no global psychomotor developmental delays. Despite this, the posture subscore was the area in which we observed the most difficulties. It is possible that the tonic dialogue between the mother and infant is disrupted by maternal depression.

The family's role in patient care was greatly altered by Law 180. This law, introduced in Italy in 1978, led to a gradual phasing out of custodial treatment for psychiatric patients. This different mindset, which views the family as an alternative to institutionalization, leads to it being seen as an essential entity in the setting up of community service dynamics. We interviewed health professionals in order to understand obstacles of collaboration between family members and mental health care workers. The goal was to uncover actions that promote collaboration and help build alliances between families and psychiatric workers. Results showed that health professionals view the family as a therapeutic resource. Despite this view, family members were rarely included in patient treatment. The reasons is: the structures have a theoretical orientation of collaboration with the family but, for nurses not are organized a few meeting spaces with family members. Services should create moments, such as multi-family groups or groups of information, managed by nurses and not only by doctors. These occasions it might facilitate the knowledge between professionals and family members.

As of 2007, there were an estimated 10.4 million businesses in the United States that were owned and operated by women. The number of women-owned firms has continued to grow at around twice the rate of all firms for the past two decades (Center for Women℉s Business Research, 2008). On the other hand, women comprise only 15.4 percent of corporate officers in Fortune 500 companies (Catalyst, 2007b) and, in 2003, held only 14.8 percent of board seats in the Fortune 500 (Catalyst, 2007a).To better understand the glass ceiling faced by both female entrepreneurs and women leaders, the research on women℉s issues is examined from a number of different vantage points. Women℉s entrepreneurship and women℉s leadership research on leadership, decision-making, and gender differences was examined to discover commonalities. Then female single-sex education literature was reviewed for insights on developmental issues that might influence future women entrepreneurs and leaders. In this exploration of research, it was found that both women entrepreneurs and women leaders in the corporate environment tend toward the same leadership styles and ways of interacting with others; they also experience a lack of role models and possible lack of self-efficacy.The literature on single-sex education provides observations that young women may thrive in environments in which there are fewer male competitors, hold less stereotyped views on gender, hold higher aspirations, may have greater opportunities for training of leadership skills, and may have increased self-confidence that may be the result of exposure to successful women role models. Implications for future research are explored and suggestions are provided to meet the needs of developing women entrepreneurs.

Stephen Hodgetts read the e-mail over and over again and still could hardly believe what he had read. He had just come back from his vacation, well rested and refreshed, and this e-mail had dampened his high enthusiasm. It took time to absorb such bad news and for Hodgetts to get over his incredulity.Yet in the end Hodgetts accepted the truth‐a deep, dark terrible truth that would not go away. Robert Davis, his business partner’s son, had confirmed in an e-mail his worst fears about their newest business partner, David Russ.Many thoughts were running through his mind simultaneously yet each screamed to be heard.“How could he and his partner Richard Davis have been so blind, so trusting?” “How could Russ not have heeded the advice of his business partner, Richard Davis, Russ’s former English professor?” And most important, “What was now going to happen to their new business?” Yet the one thought that continued to echo among them all was surprisingly a quote from Sir Arthur Conan Doyle’s beloved character, Sherlock Holmes: “But there are always some lunatics about. It would be a dull world without them.”

David Hartstein started KaBloom in 1998 with the goal of creating “the Starbucks of Flowers.” He successfully built brand recognition for the gardenlike shops, but problems plagued the young organization. Nearly three years and one recession later, KaBloom failed to live up to Hartsteinʼs forecast of exponential growth. This case has been designed for a graduate-level course in entrepreneurship/innovation. Students can compare franchising with other business models, examine the impact of organizational structure and leadership styles on business effectiveness, relate issues of supply chain management and logistics to environmental changes, and recognize the impact of innovation on business sustainability.
