Social work and information and communication technologies: the tortoise and the hare?
No full textBoth social welfare and learning delivery are changing, but they do not mirror each other in terms of their progress. The Human Services have been undergoing a business redesign process but have taken limited account of the role of communication and information technologies for training; or for external networking purposes. The more traditional tertiary education institutions have been integrating C&IT by harnessing it, but for traditional teaching methodologies and could be in danger of losing their students to more progressive teaching and learning businesses. This paper explores the impact of communication and information technologies (C&IT) on human service teaching and learning
Changing to learn: learning to change
No full textThis paper provides an overview of the use of 'communication and information technologies' (C&IT) in social work education in Britain. It outlines the development of the use of 'learning technologies' generally, and focuses specifically, on the impact of 'learning technology' in social work education and training. It looks at various factors influential in achieving, or blocking, cultural change in higher education, which may be of interest to social work educators in other countries
Changing climate drives divergent and nonlinear shifts in flowering phenology across elevations
No full textUsing a 33-year-long dataset spanning a 1267-meter semi-arid elevational gradient in the southwestern United States, we test whether flowering phenology diverged among subpopulations within species and among five communities comprising 590 species. Applying circular statistics to test for changes in year-round flowering, we show flowering has become earlier for all communities except at the highest elevations. However, flowering times shifted at different rates across elevations likely due to elevation-specific changes in temperature and precipitation, indicating diverging phenologies of neighboring communities. Subpopulations of individual species also diverged at mid-elevation but converged in phenology at high elevation.
phenology_data: Data on flowering phenology of 590 taxa collected by C. David Bertelsen over 33 years (1984-2016). A total 169,030 observations were recorded during 1,639 surveys. Data were collected along an 8.05-km trail in Finger Rock Canyon ascending from 945-2212 m, to Mt. Kimball in the Santa Catalina Mountains of Arizona, USA. The trail was partitioned into five elevation bands with distinct flowering assemblages (communities) during the growing seasons: 1) 945-1079 m, 2) 1079-1372 m, 3) 1372-1671 m, 4) 1671-1939 m, and 5) 1939-2212 m. Every species seen in anthesis (angiosperms) or releasing pollen (gymnosperms), together referred to as “flowering,” was recorded for each community along each 1.6-km-long trail segment on every survey.
temperature_precipitation_data: Temperature and precipitation data for three locations within Finger Rock Canyon in the Santa Catalina Mountains of Arizona, USA. The 1930-2016 Parameter-elevation Regressions on Independent Slopes Model (PRISM) data was downloaded from the PRISM Climate Group, Oregon State University, (http://www.prism.oregonstate.edu/explorer/), created October 25, 2017. The gauge data was collected by C. David Bertelsen
Combining social network analysis and the NATO Approach Space to define agility. Topic 2: networks and networking
No full textThis paper takes the NATO SAS-050 Approach Space, a widely accepted model of command and control, and gives each of its primary axes a quantitative measure using social network analysis. This means that the actual point in the approach space adopted by real-life command and control organizations can be plotted along with the way in which that point varies over time and function. Part 1 of the paper presents the rationale behind this innovation and how it was subject to verification using theoretical data. Part 2 shows how the enhanced approach space was put to use in the context of a large scale military command post exercise. Agility is represented by the number of distinct areas in the approach space that the organization was able to occupy and there was a marked disparity between where the organization thought it should be and where it actually was, furthermore, agility varied across function. The humans in this particular scenario bestowed upon the organization the levels of agility that were observed, thus the findings are properly considered from a socio-technical perspective
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Persistent fetal vasculature and severe protein C deficiency
No full textPersistent fetal vasculature (PFV) is most often a condition of unknown cause. It represents persisting elements of fetal ocular vessels including the hyaloid arterial network. Protein C is a vitamin K-dependent serine protease, which regulates coagulation. Deficiency of protein C leads to a prothrombotic state. We report the case of a male infant born at 34 weeks gestation to non-consanguineous parents. Ophthalmic examination found bilateral PFV, microphthalmia and vitreoretinal dysplasia. He also suffered bilateral renal vein thrombosis and purpura fulminans and was diagnosed with severe protein C deficiency. Genetic analysis of the PROC gene revealed two separate pathogenic mutations, confirming compound heterozygote status. Both parents were found to be heterozygous. While ocular manifestations (commonly haemorrhages) are often seen in protein C-deficient patients, a search of the literature reveals very few recorded cases of PFV in severe protein C deficiency. We hypothesise that protein C deficiency was the cause of PFV in this patient. Intraocular thrombotic events in utero could affect the normal development of ocular vessels and lead to persistent elements of fetal vasculature in the eye. Consideration should be given to the possibility of protein C deficiency in patients presenting with PFV, particularly if bilatera
The history of ministerial workforce policy and planning in British nursing, 1939-1960
No full textThis thesis examines the government's tripartite
approach to
workforce policy and
planning in British nursing from 1939 until
1960. Emerging histories have
placed
emphasis on the ministries and their effect upon the
development
of nursing.
However,
there remains no examination of their
distinctive
and
interrelated
roles
in
managing
nursing workforce policy and planning,
This thesis
examines the
contribution
of
three
of
these ministries from initial workforce
involvement in the
early
1940s, through to the
1950s and the advent of the Committee on
Senior
Nursing
Staff Structure
(the Salmon
Report). It concludes that three distinct roles
emerged
from
each of
the
ministries.
The
Ministry of Labour and National Service (MLNS)
dealt
with nurse
recruitment,
the
Ministry of Health addressed retention through
conditions
of service,
while
the
Colonial
Office represented replenishment. Such division
of ministerial
roles
and
any
limited
collaboration, however, did not appear to
be
a
part of
any
conscious workforce
policy.
The thesis argues that although the Ministry of
Health
and the
MLNS
viewed
nursing
as
less prestigious than a traditional profession, strategies
appealing to
nurses'
aspirations
were used to promote a sense of professional value
in
an
occupation
of
many
countervailing tensions. Nursing appeared to
occupy
its
own
unique
space
between
professions and industrial labour.
i The post-war management of the nursing workforce emerges as a
highly
reactive
policy,
focusing upon diverse groups for recruitment.
It
covered the
use
of part-time
nurses
to fit
into the social expectations of post-war women,
the
recruitment
of male
nurses and
a
manipulation of colonial legislation to the
clear
benefit
of
British
nursing.
Nurse
shortages are explored against government unease
in the immediate
post-war period with
the effects of increasing colonial immigration of
black
workers,
which
was uncontrolled
due to their status as British subjects.
The
ultimate
inadequacy
of
workforce
policies
in
nursing to deal with the recruitment of
black
nurses
remains
a
current
and controversial
workforce issue
Existential place-making : the dialogical realms of design for dwelling with disability
No full textThe world of disability is often neglected or taken for granted in able-bodied society. Apart from the challenge that disability is a social construct (Linton, 1998, 2006; Longmore, 2003; Thompson, 1997) there is an impact on the people with disability that they either feel left out or they don’t belong in the larger community. The able-bodied community is also left with very little knowledge or no sensitivity towards people with disability. These internal whirlpools do not contribute to any community only to create larger gaps and higher differences between the groups of people. \ud

Peace (2010) claims that disability is something imposed on to a person on top of a physical impairment. Nord (2008) advocates that while environmental barriers and social attitudes are crucial aspects of a person’s experience, they can indeed disable a person. \ud

The study reported high-lights what is home for people with disability and their family members. The way the person with disability and family members without disability share the same home and nurture personal relationships with each other demands greater attention. This research sheds light on the intricate relationships that exists between the family members including person with disability and their built environment. These existential connections provide a holistic viewpoint and the glimpse into the lived experiences of homes for people with disability and their care-givers. \ud

Concepts of universal design or barrier free design have not been successful (Connell and Sanford, 1999) in revealing in-depth the nature of place-making for people with disability and their care-givers. Such studies fail to incorporate the holistic needs of individuals with disability and their family members in terms of their bodily, visceral, emotional, social, psycho-social, intuitive, spiritual and temporal needs, to name a few (Franz, Bitner, 2010). This paper reports on some preliminary findings on phenomena of dwelling for people with different kinds of disability and their care-givers sharing the same home from an interior design perspective
