Logistics work to isolate local consumers from global economic violence. Under permanent threat from offshoring and automation, workers often lack the leverage to challenge wage stagnation, unsustainable production practices and labor abuses. But could we imagine a logistics that reverses this dynamic to build social power in our communities? By tracing the evolution of Just In Time logistics from Project Cybersyn, our panel will highlight practical supply chain mapping and policy tools capable of driving positive organizational change.

All that’s left of the Gospel Mission’s Christmas dinner are remnants of its beloved leftover casserole and some fresh memories of another cheerful event.
At the Mission’s annual Christmas dinner, kitchen manager Mandy Phillips said they fed nearly 700 people a total of five turkeys, 16 hams, 500 lbs of potatoes, 50 litres of gravy, eight cases of frozen vegetables, 15 cases of juice, three cases of cranberries, and 600 to 700 desserts.
“That’s all,” said Phillips, as though it didn’t take a gargantuan effort to co-ordinate a dinner that large.
The Mission always holds its Christmas dinner a week or so before the official occasion, and despite lower attendance, it’s always a well appreciated event by both the clientele and volunteers who make it work.
Politicians and members of the business community are staples of the Mission’s events, and it’s something Phillips says their clientele really appreciate.
“Some of them come again and again and people get to know them, and that’s special,” she said.
Former MP Ron Cannan proved that point as he circulated through the dining area offering up cups of coffee or tea to people he referred to by first name.
In turn, they showed they were familiar with him by engaging in cheerful banter.
One regular of the annual dinner is Arnold August. He figures he’s been going to the Mission for the last 10 years, and said that its programs as well as events like this act as a beacon of hope to those in need.
“It lets people feel loved, and puts home in their lives,” August said.
In the days to come it also puts more food in their bellies.
Phillips said once the Christmas dinner was done she’d be busily making the leftover casserole, so as not to disappoint her regulars.
“The Gospel Mission Special is the turkey, the ham, the stuffing, the mixed veggie and the potato on top and served up with gravy,” she said.
New Online Shunt Acidification for Water Injection Increasing Technology and Its Application in Huanjiang Oilfield

Introduction
e main development layer of Huanjiang oilfield is the Triassic Yanchang formation, the average porosity of the reservoir is 10.9%, and the average permeability is 0.43 × 10 −3 μm 2, so Huanjiang oilfield belongs to the ultra-low-permeability sandstone reservoir. Due to poor physical properties of the reservoir and injected water not up to standard, as well as other reasons, many problems such as uneven water absorption, increasing water injection pressure, and more and more injecting wells underinjection have arised. In recent years, aiming at the problem of underinjection of Huanjiang oilfield, a series of measures have been carried out to reduce water injection pressure and increase water injection and have achieved great efforts; however, the effective period of these measures is short (average 79 days) and effective rate is low (average 73%). e main reasons are as follows: (1) because of the repeated acidification of wells, the damaging radius is getting bigger; (2) after acidification, the acid solution produced secondary damage and caused secondary blockage to the reservoir, and (3) due to strong heterogeneity of the reservoir, acid absorption of different layers varies and low-permeability layers absorb fewer acid, resulting in poor acidification effect [1].
Based on the geological characteristics of Huanjiang oilfield, an online shunt acidification and augmented injection technology with not stopping water injection, not pulling out the original production strings, and continuous injection of acid have been proposed. e field test results showed that the technology behaves well, which could greatly reduce the water injection, improve the water injection volume, and effectively improve the profile of the wells. It has a good application prospect, and there is a bright future of the technology [2, 3].

Analysis of the Theory and Adaptability of
Online Diversion Acidification 2.1. Shunt Acidizing eory. Generally, acid flows through the small layers linearly should obey Darcy law. In order to make the acid move into the per small layer (or small section) and reach the goal of plugging removal in each layer (section) proportionately, it must obey the rule that the acid injection rate on per unit area of small layers (or small section) is the same [4], which means it should meet the following relation: In the relation, K-permeability, 10 −3 μm 2 ; ΔP-pressure difference, MPa; μ-injection viscosity, mPa·s; L-distance of pressure differential, m 3 ; and N-total amount of layers.
Due to the affect of damage degree, reservoir pressure, fluid compressibility, fluid viscosity, and natural seam hole development of small layers (or small section) [5], when measures are not taken, the relation is not met; therefore, temporary plugging or shunt technology should be considered. e online shunt acidification is an injection process which does not need to pull the original pipes out during acidification; meanwhile, acid and diverting agent are injected together with water. In the early stage, the acid prefers to enter the high-permeability layer, as the effect of the diverting agent, permeability of high permeability layer would decrease with increase entering of diverting agent, therefore, the subsequent acid would rather enter other layers with low permeability, and finally, the goal of acid entering into all layers proportionally is achieved [6].

Performance Evaluation of Chelating Acid.
Chelate acid (COA-1S) is a kind of multivariant organic acid, with 24 O 2−, 12 OH − and 6 PO 3 −, and N and O heteroatoms which contain unshared electron pairs with the greater electronegativity, and when the groups encounter Ca 2+, Ba 2+, Sr 2+, Fe 3+, and other high-valence metal cations, stable complexes are easily generated, which are very stable in the wide range of pH value [7]. Table 1 shows the chelating performance of the acid solution. It can be seen that compared with mud acid and multihydrogen acid, chelate acid (COA-1S) is superior in inhibiting precipitation, with the pH value of the solution increased from 3 to 7, the precipitation inhibition rate of COA-1S to Ba 2+ increases rapidly, indicating the increase of pH value caused by acid consumption does not reduce chelating ability, and the resulting complex are stable enough to prevent the secondary precipitate. e hydrolysis equilibrium constant of chelate acid (COA-1S) is only about 1.2 × 10 −6 ; therefore, the concentration of chelating acid is very low when hydrolysis equilibrium is reached, and the hydrolysis reaction process is slow. In the process of acidizing and plugging removal, in order to maintain the equilibrium of hydrolysis, the ionized H + generally reacts with sandstone minerals, thus slowing down the reaction rate of acid and rock and achieving the goal of plugging removal in the deep area. Comparing with conventional mud acid, the superior performance in retardation of CO
