Organizational ambidexterity: a critical review and development of a project focused definition

The objective of this paper is to explore a project-focused understanding of contemporary organizational ambidexterity literature. As part of this process, a taxonomical analysis of the elements and components of the concept of organizational ambidexterity is undertaken. Findings suggest that a project-focused notion of organizational ambidexterity involves different levels, dimensions, and mechanisms. The predominant contribution of this study resides within the taxonomy study, which provides a platform for a more holistic understanding of organizational ambidexterity as a multifaceted concept applicable to the project management discipline

Effectiveness of Yoga for Hypertension: Systematic Review and Meta-Analysis

Objectives. To systematically review and meta-analyze the effectiveness of yoga for reducing blood pressure in adults with hypertension and to assess the modifying influences of type and length of yoga intervention and type of comparison group. Methods. Academic Search Premier, AltHealthWatch, BIOSIS/Biological Abstracts, CINAHL, Cochrane Library, Embase, MEDLINE, PsycINFO, PsycARTICLES, Natural Standard, and Web of Science databases were screened for controlled studies from 1966 to March 2013. Two authors independently assessed risk of bias using the Cochrane Risk of Bias Tool. Results. All 17 studies included in the review had unclear or high risk of bias. Yoga had a modest but significant effect on systolic blood pressure (SBP) (4.17 [6.35, 1.99], ) and diastolic blood pressure (DBP) (3.62 [4.92, 1.60], ). Subgroup analyses demonstrated significant reductions in blood pressure for (1) interventions incorporating 3 basic elements of yoga practice (postures, meditation, and breathing) (SBP: 8.17 mmHg [12.45, 3.89]; DBP: 6.14 mmHg [9.39, 2.89]) but not for more limited yoga interventions; (2) yoga compared to no treatment (SBP: 7.96 mmHg [10.65, 5.27]) but not for exercise. Conclusion. Yoga can be preliminarily recommended as an effective intervention for reducing blood pressure. Additional rigorous controlled trials are warranted to further investigate the potential benefits of yoga

Organizational ambidexterity: using project portfolio management to support project-level ambidexterity

The aim of this study is to assess the ability of project portfolio management practices to support the pursuit of ambidexterity at the project level through engagement with specific dimensions and mechanisms. The focus is on examining the operating/business model and challenges that are imposed on the firms, but deemed resolvable through the simultaneous pursuit of multiple projects emphasizing contradictory strategic goals. Data are obtained from multiple exploratory interviews of senior executives involved in project-level activities who were drawn from 12 case organizations in the Middle East. The study finds evidence of four forms of ambidexterity dimensions and mechanisms. Analysis undertaken against operating/business model and challenges of these dimensions and mechanisms of ambidexterity suggests that they are not only inter-related, but do so at various organizational levels

Role of aquatic macrophytes in trophic status of Northwestern Ontario lakes

This research focusses on the development, refinement, and assessment of regional trophic status models for lakes of northwestern Ontario. Two companion papers describe the application of image analysis of aerial photographs as a technique for mapping aquatic plant distribution, and the design of an innovative sampling device to simplify the collection of macrophytes. Trophic status models were developed for lakes of northwestern Ontario, based on empirical relationships between Secchi disk transparency, total phosphorus, and chlorophyll a concentration. Corrective terms were added to the equations to adjust for the effect of water colour on Secchi disk transparency, and the effect of aquatic macrophyte abundance on the chlorophyll - phosphorus relationship. The adjusted models demonstrated an improvement in performance, as measured using standing stock of benthos as a response variable. These models would be expected to have applicability across the Precambrian Shield region of Canada. Distributional maps of aquatic vegetation were produced for area lakes using digital image analysis of aerial photographs. Recent improvements in the price and performance of computer hardware and software make this a viable alternative to the conventional, visual mapping technique. The maps produced are highly detailed, with differentiation to species possible in some instances. Certain species may be further partitioned into density classes. The authenticity of the maps depends on the ability to properly define the spectral 'signatures' for different macrophyte types. These signatures were most easily defined for floating-leafed and emergent forms; submersed vegetation proved more difficult to classify. The main detriment to this approach is the steep learning curve associated with the image analysis software. A thorough description and assessment of this technique is provided, with a discussion of its merits and deficiencies when compared with the conventional visual interpretive method. A portable macrophyte sampler was designed for use in the relatively inaccessible lakes of this region. As such, it was required to be lightweight, easily transportable, and useable by a single person. The device is effective for obtaining quantifiable biomass samples of most rooted aquatic plants over a wide variety of substrates and sampling depths. Details on the design, operation, and performance of the sampler are documented within

Reference to the index of the Marshall and Terry Family Papers.

George Marshall (1791-1881), originally of Ruthven, near Dundee, Scotland, arrived in Van Diemen's Land in 1821, and with his family settled near Sorell. His farm accounts, 1872-1883, have been preserved, together with the will of his son, David Marshall (1919) and miscellaneous notes on family history made by his grandson. One of his grandsons, Gearge Douglas Marshall, married Beatrice Terry, grandaughter of Ralph Terry (1815-1892) of Lachlan Mills, New Norfolk, so some papers of the Terry family are included. Ralph Terry came to Australia as a child early in 1819, with his father, John Terry (1771-1844) who had been a miller in Yorkshire, England. Terry purchased a windmill in Sydney but gave it up when he found he could only have a 21 year lease. The family moved to V.D.L. where, as John Terry said, there were plenty of waterfalls and a need for mills, and was granted land at New Norfolk

Polygraphs and Sex Offenders: The truth is out there

Polygraphs (or lie detectors) have been introduced into the UK for the first time despite continuing concerns about their reliability and the ways in which they will be deployed. The police are enabled to use them on a ‘voluntary’ basis and the probation service on a ‘mandatory’ basis if their use has been made a condition of post-custodial supervision. This article seeks to bring the polygraph story up to date and pose the questions that are still unanswered as the use of the polygraph begin

An examination of cooperative equity certificate transferability and farmer preferences for selected means of financing cooperatives

Farmer cooperatives have often maintained inflexible capital structures which severely restrict members' freedom to allocate their own capital in a most profitable manner. This study was conducted to provide insights into how cooperative finance programs might be modified to provide increased capital and, at the same time, be more acceptable to members. The revolving equity certificate means of finance was examined in depth. Of particular interest was the option of certificate transferability which would allow "capital-short" certificate holders the opportunity to reallocate at least a part of their investment in the cooperative association to more preferred investments on their own farms. An anlysis was designed to determine which types of farmers, according to selected farmer characteristics, would be most likely to 1) possess the highest opportunity costs for capital investments on their farms and 2) buy and/or sell revolving equity certificates at some discounted present value of the certificates' specified face amounts. Cooperative member and nonmember preferences for selected means of finance were also examined. The acceptability of alternatives such as long-term interest-bearing notes, stock certificates, revolving equity certificates, and high member ship fees was rated by the farmers in the sample. Conclusions were then reached regarding the general acceptability among farmers of selected means of cooperative finance. Several groups of farmers, according to selected farmer characteristics, expressed a desire to participate in a market for transferable revolving equity certificates. It was concluded that transferability of certificates would provide an opportunity for many farmers to allocate their own capital in a more profitable fashion. Examination of the potential buyer-side of the equity certificate market revealed a relatively thin participation except at high rates of discount. In general, cooperatives could better serve their memberships by carefully planning their alternative means of finance, with.special consideration of those alternatives which would allow the members a reasonable degree of investment flexibility
