Hope and glory: an expanded social strategy diagnosis model to incorporate corporate social responsibility within business strategy
YesCorporate social responsibility has been seen by corporations as a
practice to adopt as an act of philanthropy. There have been attempts to expand
the role of social responsibility to business problems however there has never
been an attempt to consider the strategic alignment of social outcomes to
strategy. This article analyses the role of strategy by providing a review of
strategy using Whittington’s generic strategies model and expanding the same
model to incorporate a social strategy model that supports the anecdotal idea
that social responsibility can be potentially strategic. The paper centres its
argument within the Indian context
Studying the molecular gas towards a bright rimmed cloud at the infrared dust bubble N30
We present a study on the molecular gas towards a bright-rimmed cloud located to the north of theinfrared dust bubble N30. Using the emission from the12CO,13CO, and C18O J=3?2 line, together with infraredand radio continuum data, we characterized the bubble and the related molecular cloud. In addition, we showan analysis of the behaviour of the abundance ratio13CO/C18O towards the bright-rimmed cloud, and we searchfor clues on recent star-formation.Fil: Solernó, A..

Analysis of the enabling environment for delivering land degradation neutrality in Nigeria: perspectives from the sub-national to local level
The discourse around the planning, monitoring, and assessment of land degradation neutrality (LDN) has been communicated strongly on global and national scales; however, there is relatively little information on the enabling environment that will support the achievement of LDN targets locally. Recognising the dearth of studies that apply the LDN concept at the local scale, this study investigated local stakeholders’ perspectives on the progress towards, and challenges around, establishing the enabling environment for achieving LDN. It developed and used an extended LDN enabler framework that incorporates the gender component of LDN. The data for this study were collected from stakeholders from sub-national and local institutions concerned with LDN in Nigeria. The study findings indicate the presence of several relevant institutions and policy instruments to support progress towards LDN. However, this did not create an enabling environment for land users due to the lack of sufficient funding, weak systemic capacities of the relevant institutions, and the operational challenges for delivering policy incentives. Moreover, shortcomings in the regulatory framework give rise to land tenure insecurity and gender-biased land administration systems. Also, the findings indicate that entrenched traditional norms are a major challenge in achieving gender-balanced LDN outcomes. The extended LDN-enabler framework developed in this study will extend the scope of future studies examining progress toward LDN at regional and local scales
Towards stability of food production and farm income in a variable climate
Stable food production is vital for food security. Stability of farm income is also necessary to ensure the sustainability
of food production and to protect livelihoods, in a changing climate. We analyse the relative effects of climate variability, subsidies and farming practices on the stability of food production and farm income. We examine farms in England and Wales between 2005 and 2017, and link farms to climate data at a sub-regional scale. Our results show that variability in temperature and rainfall reduces the stability of farm income and food production. While variability in climate can be largely outside of the farmers control our findings indicate that, under current conditions, farm management can have a larger effect on stability than climate. We identified three key aspects of farm management and policy that improve stability: i) increasing agricultural diversity, ii) increasing the efficiency of agrochemical use and iii) agri-environmental management. These management practices have previously been associated with benefits to natural ecosystems and may therefore increase the stability of agriculture whilst reducing negative impacts of farming on the environment. We also found differences in effect size of climate impacts and adaptation options between farm types, emphasising the need for flexible agricultural policies

Adverse weather conditions for UK wheat production under climate change
Winter wheat is an important crop in the UK, suited to the typical weather conditions in the current climate. In a changing climate the increased frequency and severity of adverse weather events, which are often localised, are considered a major threat to wheat production. In the present study we assessed a range of adverse weather conditions, which can significantly affect yield, under current and future climates based on adverse weather indices. We analysed changes in the frequency, magnitude and spatial patterns of 10 adverse weather indices, at 25 sites across the UK, using climate scenarios from the CMIP5 ensemble of global climate models (GCMs) and two greenhouse gas emissions (RCP4.5 and RCP8.5). The future UK climate is expected to remain favourable for wheat production, with most adverse weather indicators reducing in magnitude by the mid-21st 17 century. Hotter and drier summers would improve sowing and harvesting conditions and reduce the risk of lodging. The probability of late frosts and heat stress during reproductive and grain filling periods would likely remain small in 2050. Wetter winter and spring could cause issues with waterlogging. The severity of drought stress during reproduction would generally be lower in 2050, however localised differences suggest it is important to examine drought at a small spatial scale. Prolonged water stress does not increase considerably in the UK, as may be expected in other parts of Europe. Climate projections based on the CMIP5 ensemble reveal considerable uncertainty in the magnitude of adverse weather conditions including waterlogging, drought and water stress. The variation in adverse weather conditions due to GCMs was generally greater than between emissions scenarios. Accordingly, CMIP5 ensembles should be used in the assessment of adverse weather conditions for crop production to indicate the full range of possible impacts, which a limited number of GCMs may not provide

maternal colonization and neonatal infection with group B Streptococcus
Aim and Objective: During the past three decades, group B Streptococcus (GBS) neonatal infection has
been the subject of little research. The aim of this study was to evaluate the association between maternal
risk factors, as established by the Center for Disease Control and Prevention (CDC), and maternal
colonization. We also analysed the association between risk factors present in newborns and early-onset
GBS disease.
Study design: Cross-sectional study.
Population: All pregnant women admitted for delivery in our institution and their newborns,
between 1st February and 31st July 2005.
Methods: Maternal and neonatal characteristics were collected from hospital clinical data, including
information on risk factors established by the CDC. Descriptive statistics was used to characterize
the study sample. Qui-square and Mantel-haenszel tests were applied to compare proportions and to
measure the strength of associations, respectively, setting significance at p < 0,05.
Results: In this sample only 47% of women were screened for GBS colonization in suitable time and
34,9% of these women were colonized. The incidence of early neonatal infection by SGB was 9/1000
neonates. Significant associations between GBS maternal colonization ant the following parameters
were observed: maternal age [p=0,012; OR=1,659 (IC a 95%, 1,218-2,260)], gestational age at
labour [p=0,001; OR= 2,621 (IC a 95%, 1,641- 4,188)], and urinary GBS infection during pregnancy
(p<0,001). Maternal colonization occurred in women without CDC defined risk factors. Early neonatal
infection by SGB was strongly associated with unscreened women (p=0,014).
Conclusion: In this study, maternal GBS colonization occurred in the absence of CDC defined risk
factors and varied according to maternal age and gestational week. Neonatal GBS infection was more frequent in unscreened women
