Winter rye (Secale cereale L.) antioxidant capacity, total phenolic content and quality indices

Rye (Secale cereale L.) grain is an excellent raw material for healthy and tasty foods. Rye products are characterized by their unique composition and properties such as antioxidant capacity and total phenolic. The aim of the study was to assess radical scavenging capacity, total phenolic content, protein, starch content and falling number in rye varieties wholemeal. The trial included population winter rye varieties ‘Kaupo’, ‘Amilo’, ‘Dankowskie Amber’, ‘Dankowskie Rubin’, ‘Inspector’ and hybrid rye varieties ‘SU Drive’, ‘SU Mephisto’, ‘SU Bendix’, ‘Brasetto’, ‘Palazzo’ grown in Latvia. The antioxidant activity was determined using the DPPH (2.2-diphenyl-1-1-picrylhydrazyl radical) assay and total phenolic content was determined spectrophotometrically according to the Folin-Ciocalteou method. The rye grain antioxidant capacity was estimated as Trolox equivalent, while the total phenolic content was expressed as gallic equivalents (GAE). ‘Su Drive’ rye variety contained the largest amount of total phenolic (average 208 mg GAE 100 g -1 DW), but the lowest – ‘Inspector’ rye variety 176 mg GAE 100 g -1 DW. In general, all rye samples tested in this study demonstrated similar level of antioxidant capacity (from 38.5 to 46.2 mmol Trolox eq. 100 g -1 ). Statistically higher (P < 0.05) total phenols content and falling number had hybrid rye grains, compared to the population rye grains. In the present trial, the differences between hybrid varieties grains protein and starch content comparing to population varieties were not observed

The Association of Physical Activity and Academic Behavior: A Systematic Review

BACKGROUNDIn this systematic review, we assessed the existing research describing the effects of physical activity (PA) on academic behavior, with a special focus on the effectiveness of the treatments applied, study designs, outcome measures, and results.METHODSWe obtained data from various journal search engines and 218 journal articles were downloaded that were relevant to PA and academic performance topics. The abstracts of all the articles were independently peer reviewed to assess whether they met the inclusion criteria for further analysis. The literature search was ongoing. Of the reviewed articles, 9 were chosen on the topic of PA effects on academic behavior. Each article was analyzed and summarized using a standard summary template.RESULTSOverall, PA interventions commonly found positive effects on academic behavior, with few exceptions. There were additional unique findings regarding differences in outcome measures and PA treatments.CONCLUSIONSThe findings from these studies are significant and support the implementation or continuation of PA in schools to improve academic behavior and associated performance. More research needs to be conducted using the effective aspects of the treatments from this review with consistent outcome measures.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/136401/1/josh12502.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/136401/2/josh12502_am.pd

The construction of identities in narratives about serious leisure occupations

Engagement in occupation contributes to the shaping of identity throughout the human life. The act of telling about such engagement involves interaction based on symbolic meaning; the speaker constructing an identity by conveying how the occupation is personally meaningful. This study explored meaning in narratives told by people who engage in serious leisure occupations. A total of 78 narratives were extracted from interviews with 17 people who invest considerable time and other resources into their leisure. Analysis focused on the content, structure and performance of each narrative in order to explore meaning. The meanings were organised into a framework based around three dimensions: the located self, the active self and the changing self. Each dimension has facets that the individual might emphasise, constructing a unique identity. The framework offers a structured basis for conceptualising how occupation contributes to the shaping of the internalised self and the socially situated identity

Nursing Facility Residents’ Cardiopulmonary Resuscitation Decisions

Context As many as one-quarter of all residents in nursing facilities have cardiopulmonary resuscitation (CPR) as a documented choice in the medical record, despite the likelihood of limited medical benefit in this setting. Objectives The aim of this study was to understand the perspectives of healthcare providers and nursing facility residents regarding CPR decisions. Methods We used qualitative interviews to examine the perspectives of residents with a documented decision for CPR in the medical record. We then compared residents’ views with those of healthcare providers who routinely conduct advance care planning (ACP) conversations in the nursing facility setting. Results Five themes emerged from the interviews: (a) Resident versus Provider Concerns, (b) Offering Information versus Avoidance, (c) Lack of Understanding of CPR, (d) Lack of Awareness, and (e) ‘Don't Keep Me on Machines'. Residents held misconceptions about CPR and/or exhibited an overall poor understanding of the relationship between their own health status and the likelihood of a successful CPR attempt. Although healthcare providers offer information and health education in an attempt to address knowledge gaps, these efforts are not always successful or even accepted by residents. Resident viewpoints and priorities differed from healthcare providers in ways that affected communication about CPR. Conclusions Unrecognised differences in perceptions between providers and residents affect key aspects of ACP communication that can impact CPR decision-making. The concerns and priorities of institutionalized older adults may differ from those of healthcare providers, creating challenges for engaging some residents in ACP. Implications for Practice ACP communication models and training should be designed not only to explore nursing facility residents' goals, values, and preferences, but also to elicit any underlying differences in perceptions that may affect communication. Healthcare providers can identifying the primary concerns of residents and assist them with integrating or reframing these issues as a part of ACP discussions

Anointed or appointed? Father–daughter succession within the family business

With the focus on events and outcomes shaping most of the existing family business research on intra-family succession, the subtleties of the incumbent-successor relationship and the dynamic nature of succession as a process of becoming is somewhat neglected. In particular, we have limited understanding of how successor identities are constructed as legitimate between incumbent and successor during father-daughter succession. This article addresses this gap in understanding by exploring how the daughter successor engages in identity work with the father incumbent during the process of succession and the role of father-daughter gendered relations in shaping her successor identity. Using a two-stage research design strategy, we draw upon empirical evidence derived from 14 individual and joint semi-structured interviews to present a narrative analysis of five father-daughter dyads. In so doing, we unveil how the daughter’s successor identity was co-constructed as legitimate and how father-daughter gendered relations influenced this process. Although daughters rely on certain father-daughter relations (preparation, endorsement and osmotic credibility) for legitimacy, they also need to develop independently from their father in order to heighten their own visibility and establish credibility

Research in Medical Education: Balancing Service and Science*

Since the latter part of the 1990’s, the English-speaking medical education community has been engaged in a debate concerning the types of research that should have priority. To shed light on this debate and to better understand its implications for the practice of research, 23 semi-structured interviews were conducted with “influential figures” from the community. The results were analyzed using the concept of “field” developed by the sociologist Pierre Bourdieu. The results reveal that a large majority of these influential figures believe that research in medical education continues to be of insufficient quality despite the progress that has taken place over the past 2 decades. According to this group, studies tend to be both redundant and opportunistic, and researchers tend to have limited understanding of both theory and methodological practice from the social sciences. Three factors were identified by the participants to explain the current problems in research: the working conditions of researchers, budgetary restraints in financing research in medical education, and the conception of research in the medical environment. Two principal means for improving research are presented: intensifying collaboration between PhD’s and clinicians, and encouraging the diversification of perspectives brought to bear on research in medical education

COMPUTER-CONTROLLED GAS CHROMATOGRAPH CAPABLE OF ''REAL-TIME'' READOUT OF HIGH-PRECISION DATA.

A gas chromatograph has been assembled which provides computer control of sample injection, column temperature, and flow rate, plus direct computer readout of inlet pressure, mass flow rate, and detector response. Data processing yields, in real-time, a standard deviation of less than 0.05% in retention time, which is comparable to previous results obtained using an off-line computer. However, corrected retention volumes determined in real-time had a standard deviation of about 0.4% which reflected primarily the uncertainty in flow measurement
