Constant Connectivity and Boundary Management Behaviors: The role of Human agency

The surge of remote and hybrid work in the post-pandemic era reinforced the blurred boundaries between work and non-work responsibilities. Thus, how people manage the boundaries between work and non-work domains has become more complicated. This study advances the previous studies on constant connectivity by focusing on how employees’ perception of constant connectivity might actualize their boundary management behaviors. Additionally, we concentrated on contextual factors, including IT/internet policies, informal social norms, and work flexibility, to investigate how these factors could influence employees’ perception of constant connectivity. This paper reports a two-phase study. In the first phase, we used sentiment analysis to rank 38 internet use policies of Australian universities for grading their strictness toward ICT/internet use. Next, building on the first phase, we interviewed 28 academics. We identified three perceptions of constant connectivity, including constant connectivity as a resource, a challenge, and a duality. We also found five distinct boundary management behaviors connected to three different perceptions

Digital intrusions or distraction at work and work-Life conflict

Internet usage for non-work activities during work hours is an increasingly common concern among management scholars and practitioners as well as for employees, particularly in relation to its impact on work-life conflict and individual well-being. Drawing on memory for goals theory, this study investigates the distinction between digital intrusions and digital interruptions during work and their concomitant impact on work-life conflict. Using a set-theoretic approach to analyse data gathered from information technology (IT) professionals in Germany and Australia, we explain how a 2 * 2 matrix comprising non-work online messaging, or personal digital communication, during work and intrusion contributes to work-life conflict. A key finding is that employees reported work-life conflict only if they perceived private messaging as a source of intrusion rather than as a distraction. From a practical perspective, this finding suggests that employers may provide employees with micro-breaks to attend to perceived intrusions and thus reduce sources of work-life conflict. Contributions and suggestions for future studies are discussed

Comparison of knowledge, attitude and practice of Urban and rural households toward iron deficiency anemia in three provinces of Iran

Background: Lack of nutritional knowledge is one of the most important reasons of nutritional problems and consequently improper practice, which can lead to several complications. This study has been designed in order to compare knowledge, attitude and practices of the urban and rural households regarding iron deficiency anemia (IDA) in Boushehr, Golestan and Sistan & Balouchestan provinces in 2004. Methods: The sampling method at household's level in each province was the single-stage cluster sampling with equal size clusters. The necessary data were gathered with a structured questionnaire and via the interviews between the questioners and the eligible people in each household. Comparison of frequency of variables between urban and rural areas were tested by chi square test. Results: A total of 2306 households were selected as overall sample size. In urban areas, people recognized iron food sources better than rural areas. Knowledge level of respondents about vulnerable group for IDA and the favorite attitude of households toward IDA were better in urban areas of Sistan & Blouchestan and Golestan provinces. In Sistan & Balouchestan and Golestan, rural households who drank tea immediately before or after meal was more than urban ones. The majority of pregnant and lactating mothers (except for rural areas of Bushehr) did not take iron supplement regularly. Less than 60 percent of children used iron drop regularly. Conclusion: Knowledge, attitude, and practice levels of households toward IDA were not acceptable. One of the best ways of improving nutritional practice is nutritional education with focus on applying available food resources

Gastric hibernoma: a novel location and presentation of a rare tumor.

We present a case of gastric hibernoma, an unusual tumor with a location novel to the literature. A 39-year-old female presented with one year of upper gastrointestinal bleeding and dysphagia. Gastroenterology performed an esophagogastroduodenoscopy with ultrasound and identified a 6 cm mass within the muscularis propria of the antrum. Computed tomography demonstrated a 9.7 × 7.8 × 4.8 c

Should I stay or should I go? Skilled immigrants' perceived brain-waste and social embeddedness

Purpose: Drawing on embeddedness theory, we examine how skilled immigrants' perceived brain-waste affects their social embeddedness. Social embeddedness facilitates the acquisition of host country-specific human capital, which, in return, can accelerate the transfer of immigrants' human capital in the workplace. Design/methodology/approach: In total, 397 skilled immigrants in Australia participated in this study. We applied a set-theoretic approach to decode the complexity and interplay among the key concepts used in this study. Findings: We found the impacts of psychological workplace wellbeing and workplace discrimination on social embeddedness differ between skilled immigrants who experience perceived brain-waste and skilled immigrants whose skills were recognized by employers. The results suggest that job satisfaction is the most critical factor contributing to social embeddedness among skilled immigrants who did not report brain-waste. Furthermore, we found that married skilled male immigrants who reported brain-waste still could embed socially if they did not directly experience workplace discrimination. Originality/value: The majority of previous studies have compared skilled immigrants with their local-born colleagues, but we compared two groups of skilled migrants in the current study. We adopted fuzzy-set qualitative comparative analysis to test how unique configurations of several variables can ease their social embeddedness into the host society

Automated distal coronary bypass with a novel magnetic coupler (MVP system)

AbstractObjectiveWe sought to assess the feasibility of performing sutureless distal coronary artery bypass anastomoses with a novel magnetic coupling device.MethodsFrom May 2000 to April 2001, single-vessel side-to-side coronary artery bypass grafting on a beating heart was performed in 39 domestic white pigs (35-60 kg) without the use of mechanical stabilization, shunts, or perfusion bridges. Animals were divided into 2 groups. Seventeen pigs underwent right internal thoracic artery to right coronary artery bypass grafting through a median sternotomy (group 1) with a novel magnetic vascular positioning system (MVP system; Ventrica, Inc, Fremont, Calif). Twenty-two pigs underwent left internal thoracic artery to left anterior descending artery grafting with the MVP anastomotic device through a left anterior minithoracotomy (group 2). This system consists of 2 pairs of elliptical magnetic implants and a deployment device. One pair of magnets forms the anastomotic docking port within the graft; the other pair forms an identical anastomotic docking port within the target vessel. The anastomosis is created when the 2 docking ports magnetically couple. Anastomotic patency was evaluated by means of angiography during the first postoperative week and at 1 month. Histologic studies were performed at different time points as late as 6 months.ResultsRight internal thoracic artery to right coronary artery anastomoses and left internal thoracic artery to left anterior descending artery anastomoses were successfully performed with the system in all animals. The self-adherent and self-aligning properties of the implants allowed for immediate and secure approximation of the arteries (total anastomotic time between 2-3 minutes). Anastomoses were constructed without a stabilization platform. Five nondevice-related deaths occurred postoperatively. One-week angiography, performed in 35 surviving animals, showed a patent graft and anastomosis in all cases. The patency rate at 1 month was 97% (33/34). Histologic studies as late as 6 months demonstrated neointimal coverage of the magnets without any significant luminal obstruction. Histology also confirmed the presence of viable tissue between magnets.ConclusionThe MVP anastomotic system uses magnetic force to create rapid and secure distal coronary artery anastomoses, which might facilitate minimally invasive and totally endoscopic coronary artery bypass surgery

Extended Functionalities of Photovoltaic Systems with Flexible Power Point Tracking:Recent Advances

The power system is experiencing an ever-increasing integration of photovoltaic power plants (PVPPs), which leads demand on the power system operators to force new requirements to sustain with quality and reliability of the grid. Subsequently, a significant quantity of flexible power point tracking (FPPT) algorithms have been proposed in the literature to enhance functionalities PVPPs. The intention of FPPT algorithms is to regulate the PV power to a specific value imposed by the grid codes and operational conditions. This will inevitably interfere the maximum power point tracking (MPPT) operation of PV systems. Nevertheless, the FPPT control makes PVPPs much more grid-friendly. The main contribution of this paper is to comprehensively compare available FPPT algorithms in the literature from different aspects and provide a benchmark for researchers and engineers to select suitable FPPT algorithms for specific applications. A classification and short description of them are provided. The dynamic performances of the investigated algorithms are compared with experimental tests on a scaled-down prototype. Directions for future studies in this area are also presented.MOE (Min. of Education, S’pore)Accepted versio

Liver regeneration in dogs: Morphologic and chemical changes

Forty-four percent and 72% hepatectomy were carried out in dogs and the animals were sacrificed for biochemical and pathologic studies from 0.5 to 6 days later. Compensatory hypertrophy and hyperplasia ("regeneration") were evident within 1 day, reached a maximum in 3 days, and were almost complete by 6 days. Coincident with the histologic events of regeneration were decreases in responsiveness of receptor adenyl cyclase to glucagon stimulation, increases of cyclic AMP, inconsistent changes in plasma insulin, and increases in plasma glucagon. These studies have standardized hepatic resection in dogs and they have focused attention upon some possible mechanisms that will require further study. © 1978 Academic Press, Inc.
